OPTIMISING CLEAN-IN-PLACE PROCESSES IN FOOD AND BEVERAGE OPERATIONS PART 1 Benjamin Jude and Eric Lemaire*

4 WHAT'S NEW IN PROCESS TECHNOLOGY - OCTOBER 2014

www.ProcessOnline.com.au

Clean-in-place (CIP) processes are often intensive and waste large amounts of energy, water, and chemicals. New innovations in CIP technology allow plant operators to cut costs in an environmentally friendly manner while still conforming to regulatory safety standards.

Many manufacturers are unsure of how their CIP systems are performing. Therefore additional steps are often introduced as a safeguard to ensure adherence to sanitation standards. This practice results in higher consumption of water, chemicals, and energy than is necessary in order to avoid the contamination issues. A number of companies have addressed CIP improvements with small modifications such as altering the chemical concentration, or by adjusting the time taken for each stage of the CIP process. However, very few food and beverage manufacturers have put tools in place that render the CIP process efficient. In fact, in an informal poll conducted by Schneider Electric on food and beverage clients in France, only 12% thought that their CIP systems were efficient yet only 18% of those surveyed had commenced a study around CIP optimisation. Yet industry leaders are clearly indicating that progress needs to be made in the areas of waste reduction and water and energy efficiency (see Figure 1). Recent innovations in technology now enable plant operators to calculate the optimal mix of water, chemicals, temperature and flow required to achieve safety standards while saving at least 20% in energy cost and by reducing the downtime for cleaning by at least 20%. In addition, all the steps in the process can be easily traced and auto-

matically documented, which simplifies any auditing requirements that need to be performed by regulatory inspectors.

Risks of inefficient and ineffective CIP systems Food safety and litigation With many hundreds of metres of pipework, and a multitude of valves, pumps and instrumentation that make up a typical CIP system (see Figure 2), the risk of equipment failure is high and can happen at any stage of the process with a potential impact on food safety. It is quite difficult to verify that all aspects of the cleaning process have been taken into account. Consider the instance of an operator who runs a cleaning process and does not even realise that a particular component (such as a pump) did not work because no alarm was generated. The result of improper cleaning is costly to a plant in violation of food and beverage industry safety regulations. The all-too-frequent incidences of food safety disasters around the globe are often caused by simple mistakes or faulty processes in a food or beverage factory which lead to sickness, injury, and even death for those who consume contaminated products. In addition to the human tragedy, these contamination incidents lead to the expense of product recalls, loss of confidence in a company’s brand, and ultimately loss of revenue. Food safety authorities conduct plant audits to ensure that the critical control points identified as HACCP (hazard analysis and critical control points) are monitored and reviewed for regulatory compliance and continuous improvement. In the event of a contamination incident, full traceability (enabled by software) and ‘proof of clean’ will reduce the legislative and legal impact. The company involved will be in a better position to identify the contamination impact and to minimise the effort required to implement a withdrawal or recall procedure.

OCTOBER 2014 - WHAT'S NEW IN PROCESS TECHNOLOGY 5

typical clean-in-place (CIP) process requires large amounts of water, chemicals and energy. It is estimated that, on average, a food and beverage plant will spend 20% of each day on cleaning equipment, which represents significant downtime for a plant. Energy usage varies depending on the process. For example, a milk plant is likely to use 13% of its energy on CIP, whereas a powdered milk, cheese and whey process is likely to use 9% of its energy on CIP1. In a fruit jam manufacturing facility in Manchester, England, cleaning hoses in the fruit room were identified as one of the highest end users of water in the facility (17% of total site water consumption)2.

Automation

A 20% REDUCTION IN CLEANING TIME WILL DELIVER APPROXIMATELY AN EXTRA HOUR OF PRODUCTION TIME TO EACH DAY.

Figure 1: Top sustainability priorities of food and beverage, and consumer products industries.

Production downtime Lowering operational expenditure and reducing waste to lower the cost of production without impacting product quality are universal goals of food and beverage enterprises. However, when a CIP process is in operation, production is stopped. This impacts profitability. As a result, two tendencies manifest themselves which are both negative to the business: 1. When a problem occurs, there is a natural reaction to avoid seeking the root cause of the problem. Such an intervention could involve even more time-consuming maintenance work. 2. With the risk of contamination at the forefront of most operators’ minds, the tendency of the CIP operator is to overcompensate with increased cleaning time. Fortunately, new CIP technologies alleviate the above problems because of significant improvements in efficiency: • More advanced CIP automation enables dramatic reductions in troubleshooting time in the event of a problem, cutting what once took hours to perform into minutes of diagnostics. • An optimised CIP process can reduce cleaning times by up to 20%. If CIP currently takes around five hours of each day, a 20% reduction in cleaning time will deliver approximately an extra hour of production time.

High consumption of energy and water Efficiency improvement does not only focus on reducing cycle time, as well as energy, water, and chemical consumption. The primary purpose of the CIP system is to remove fouling from the equipment. When

production equipment is not completely clean, expensive raw materials have to be thrown out. Effective cleaning results in fewer instances of contamination and therefore improved production efficiency. The cleaning function, however, is energy intensive. Almost half of a milk-processing facility’s energy is used to clean the processing lines and equipment4. Calculating the precise temperature needed to clean equipment is critical to reducing the energy consumption. For every 1°C reduction in CIP temperature there will be a 1/60th reduction in the energy needed to heat the fluid5. The amount of water or chemicals used can also be reduced by introducing recovery tanks so that the liquid can be re-used instead of sent down the drain.

Loss of innovation and flexibility Food and beverage manufacturers must innovate in order to remain competitive. Recipes need to be improved and new product lines developed. Therefore, CIP systems need to be flexible in order to adapt to different types of fouling on the equipment as product lines evolve. Operators need to be able to alter cleaning recipes to suit particular types of fouling, whether product (sugar, fat, protein, or minerals) or microbial (vegetative microorganisms, or spore forming microorganisms) and ensure that the CIP system is operating in an efficient manner. Chocolate, for example, will require a different cleaning recipe for butter than it will for flour. Modern CIP systems, equipped with automation software enable a simple drill down into any aspect of the process. This traceability of the system offers a number of benefits:

6 WHAT'S NEW IN PROCESS TECHNOLOGY - OCTOBER 2014

1. Operators can check each CIP operation to verify whether it has worked correctly 2. Diagnostics are simple to perform and deliver detailed information on each element of the cleaning cycle 3. Faults and issues can quickly be highlighted and rectified 4. Plant managers can generate detailed operational reports 5. Food security reporting to regulators is easy to assemble and more comprehensive

Incremental process improvements Equipment manufacturers ensure that CIP systems are installed and in good working order but these systems need to be finetuned based upon the environment of the particular plant. Some food and beverage manufacturers have tried to improve the efficiency of their CIP systems. The process usually involves a manual, trial-and-error approach which does not consider a holistic view of the system. These efficiency improvement techniques involve the following: • Modifying chemicals: New chemicals can be experimented with or the concentration of existing chemicals can be altered to see if cleanliness is achieved more easily. The risk is that new versions may prove to be more costly. • Altering cleaning times: Increasing or decreasing the time taken for rinse or for chemical solution cycles may result in some efficiency gains although the balance of downtime to production output and impact on safety tolerance levels will need to be reconsidered.

Automation

A HOLISTIC APPROACH INCORPORATING AUTOMATION SOFTWARE MAKES THE BIGGEST IMPACT ON COST SAVINGS AND SAFETY IMPROVEMENT.

Figure 2: Example of a simple single line CIP system.

• Adjusting water temperature: Increasing the temperature of water to decrease the cleaning time or conversely decreasing the temperature to lower energy costs are also possible options. • Reconfiguring settings: A study of CIP line usage can be a useful way to improve production efficiency. For example if line 1 is at 100% capacity and line 2 is rarely used, a simple rebalancing would be to move some equipment cleaning to line 2. • Maximising chemical effectiveness: The introduction of enzyme-based detergents to speed up chemical reactions or membranes to filter chemicals and enable them to be re-used for longer helps save resources. • Implementing eco-friendly solutions: Bio-decontaminants eliminate the need for the use of harsh chemicals and can help reduce the amount of energy, time and water for the cleaning process. • Using ozonated water: Disinfection with ozonated water is effective on a range of microorganisms and can save on water, chemicals, and energy. The typical five-tank process is reduced to just three and it is extremely safe for the environment because its by-product is oxygen. However it may be more costly to implement into an existing CIP system as it requires the addition of an ozone station and other equipment on site. • Developing a conservation mindset: The replacement of faulty valves and fittings, switching off water sprays and hoses when not in use, and disconnecting or removing redundant pipework help to improve efficiency. Installing meters on equipment will help to monitor water

consumption. An example of this is installing flowmeters on inlet and outlet pipes to verify the volume of liquid sent and received. This can be analysed to identify any unusual losses through the leak chamber of the valve. Each of these above strategies is often performed in isolation and the outcomes documented. The downside of this trial-anderror approach is that it is time consuming and much waste is generated in trying to determine the proper mix of water, chemicals, and energy. This tweaking of the CIP system can deliver some benefits, however a holistic approach incorporating automation software makes the biggest impact on cost savings and safety improvement. The complexity of finding the optimal combination for cleaning the equipment while meeting required standards is simplified thereby saving time, reducing errors, and lowering water use and energy consumption.

In Part 2 In Part 2 of this article, the benefits of using an automated CIP system will be discussed, along with examples of the efficiencies that are gained by doing so.

OVERMOULDED SPLITTER Turck has announced the availability of a redesigned VB2 splitter with LEDs. The updated VB2 features a translucent black, overmoulded design, which encapsulates the LEDs and protects them from physical damage while also complimenting visibility. The design enhancement also enables the LEDs to be visible from both sides of the splitter, allowing it to be mounted on either side - the previous version only allowed mounting on one side for the LEDs to be visible.

DIGITAL VALVE CONTROLLERS Emerson Process Management has introduced the Fisher Fieldvue DVC6200p series of digital valve controllers. The DVC6200p series is a suitable solution for applications in which accessibility, extreme temperatures (up to 120Â°C), extreme vibration or confined space make integral mounting difficult or impractical. Industries such as pulp and paper, and metals and mining, have typically preferred to isolate valve-mounted instruments from harsh environments.

CASE STUDY

Australia’s largest palletising system

George Weston Foods (GWF) new production facility in Castlemaine, Victoria, is now home to Australia’s largest robotic palletising system. GWF is one of Australia and New Zealand’s largest food manufacturers, employing around 8000 people at nearly 60 sites. Producing a wide range o f s m a l l g o o d s w h i c h a re supplied to consumers through the retail food service and small distributor networks, the factory is divided into four key plants: ham, bacon, salami and continental smallgoods. Each of these production areas is serviced by a shared palletiser and distribution service. The system palletises over 450 different products at the rate of about 9000 cartons/h, coming from four different packing areas. Some 27 lines and more than a kilometre of conveyors bring products into the palletising cell, which has 16 ABB robots serving 32 pallet stations and another robot at the front of the station preparing the pallets. Finally, two rail systems with four shuttles deposit the finished pallets at two stretch wrapper stations, which wrap more than 100 loaded pallets an hour and feed them to the automated guided vehicles (AGVs). Melbourne-based Andrew Donald Design Engineering (ADDE) designed and installed the system for GWF. Barry Hendy, ADDE general manager, knew that ABB robots were a perfect fit for the food producer: “We chose ABB’s IRB 4600 robot because the orientation and positioning of the cartons needed a sixth axis, so we needed the extra dexterity of a six-axis robot to ensure the stations would be able to handle all of the palletising tasks coming in from the conveyors.” Line configuration was chosen based on the speed of the individual lines. Each automated row is able to look after two lines and maintain the rates on those two lines, which dictates the line configuration of 16 robots, serving the 32 pallet stations.

16 WHAT'S NEW IN PROCESS TECHNOLOGY - OCTOBER 2014

“Before implementing the robots the problems we experienced were from manual handling, including occupational, health and safety (OHS) issues, downtime, not getting the products out fast enough and labour costs,” said GWF packaging team leader Troy T h o m a s . “ I t h i n k t h e defining factor was in knowing that we could eliminate a lot of manual handling and remove a fair bit of the labour costs associated with the manual handling.” Kim Martin, GWF’s supply chain manager, agreed: “We had challenges with retailers in terms of making sure the consistency and quality of the pallets were what they required for their automated networks. And like everyone else, we also had increasing labour costs and concerns about our ability to reach the productivity targets we needed in order to remain competitive.” The market trend is towards smaller, more shelf-ready pack sizes. “Obviously that increases the repetitiveness of the tasks the team here needed to do, therefore increasing our OHS risk as well, which is probably the main risk that we have onsite,” said Martin. He also revealed that the company upgraded its ability to manage production speed a n d vo l u m e a t i t s c e n t ra l distribution space, and that the installation also brought improvements to worker safety. “Other improvements include significantly reduced levels of pallet rejections from customers and the ability to deal smoothly with the production volume now being processed out of this site as each of the facilities has come online,” he said. “We have also seen a huge improvement in OHS injuries associated with palletising, because we have largely eliminated that task.” ABB Australia Pty Ltd www.abbaustralia.com.au

POWER SUPPLY DECOUPLING DIODE The Phoenix Contact Uno Power diode, which is 22.5 mm wide, decouples power supplies connected in parallel, thereby increasing operational reliability. Due to their high power density, the power supply units in the Uno Power power supply range are suitable for loads up to 100 W, especially in compact control boxes. When used in sensitive applications that require high availability, redundant power supplies are recommended. If the power supplies, which are operated in parallel, are also decoupled by the diode, a short circuit at the output of one of the power supply units or in the supply line from the power supply unit to the diode will have no effect on the load. The diode operates with an input voltage range of 4.5 to 30 VDC and nominal input currents of 2 x 10 A or 1 x 20 A. The module is snapped onto the DIN rail without spacing either side and operates at ambient temperatures from -25 to +70째C, making it suitable for industrial use. There are 15 corresponding Uno Power power supplies with output voltages from 5-48 VDC currently available. The power supply units reduce energy consumption through low idling losses below 0.3 W and optimised efficiency of over 90%. Phoenix Contact Pty Ltd www.phoenixcontact.com.au

CASE STUDY

Project Magnet extends the life of Whyalla Steelworks Arrium Mining is a leading Australian resources company, currently exporting at a rate of 12 million tonnes of hematite ore to China per annum from its Middleback Ranges and Peculiar Knob mining operations in South Australia. The company has three key businesses: mining, mining consumables, steel and steel recycling. A significant milestone in the company’s history occurred in 2005 when Arrium decided to diversify into the resources sector through Project Magnet which would convert the Whyalla Steelworks to a magnetite iron ore feed, creating a new revenue stream for the company by making hematite iron ore available for export sales. A project of this magnitude would require a completely integrated control system, enabling visibility for any operator station across the pit-to-port operations. To achieve this, Arrium Mining called on the expertise of LogiCamms together with Rockwell Automation to deliver a solution that would not only extend the life of the Whyalla Steelworks but also reduce the cost of steelmaking while incorporating environmental improvements. With the mine site located approximately 60 km from the Whyalla Steelworks, a slurry pipeline was built to allow magnetite to be transported through the pipe to Whyalla. Concurrently, hematite ore continued to be transported by rail to the port for shipping. The three main areas of the operation that required complete control system integration were the materials handling area, which involves the handling and storage of hematite for export; the filter/flux area which receives magnetite from the slurry pipeline and prepares it for feeding to the existing pellet plant; and the mine concentrator area. A challenging aspect of this project was the distance involved in connecting the concentration plant which was near the mine site to the filter/flux which is located at the steelworks more than 60 km away. “This was addressed by utilising Ethernet across a large fibre-optic network. FactoryTalk View provided visibility at any operator station across the whole of the pit-to-port operation,” said Greg Schultz, executive account manager - mining, Rockwell Automation. To provide reliable and secure control system integration based on the ControlLogix platform, multiple redundant control systems were used. Low- and medium-voltage drives were also provided for the pumping and crushing equipment, and safety components including Guardmaster safety relays were incorporated into the motor control centre design.

22 WHAT'S NEW IN PROCESS TECHNOLOGY - OCTOBER 2014

“This application was one of the largest FactoryTalk View applications to be completed at the time and high-level support from the Software Business Unit of Rockwell Automation was invaluable in the success of the solution,” said Andrew Thompson, senior engineer - control systems for LogiCamms. According to Jonathon Deluao, principal control systems engineer, Arrium Mining, “The solution has provided full integration and a high level of process control which gives us the ability to control and modify the system according to the production needs.” “We now have a fully automated plant that is flexible enough to cater to our needs both production wise and process wise,” continued Deluao. The transition of the Whyalla Steelworks from hematite to magnetite feed has changed the iron ore pellet process from a dry to a wet process. As the magnetite ore is pumped via a slurry pipeline from the mine to the steelworks, the level of fugitive dust emissions are reduced, which greatly benefits the Whyalla community. Project Magnet has also fostered the use of covered facilities for loading iron ore and the relocation of the crushing and screening area to the mine site, which has resulted in further improvements in environmental conditions for Whyalla. A trans-shipping service has also been introduced to avoid major dredging of the Whyalla Port and a new fleet of high-sided wagons has been put into service. The benefits from Project Magnet play an important part in enhancing the sustainable competitiveness of the Whyalla Steelworks. The successful implementation of Project Magnet has essentially provided a new lease of life for the Whyalla steelworks by extending the life span from the expected 2020 constraint imposed by hematite ore reserves, to at least 2027. Based on the success of Project Magnet, Arrium Mining has opened another mine using a complete solution from Rockwell Automation. “We have migrated to a completely integrated Ethernet network with advanced segregation and security components,” said Deluao. Through combining leading technology with high-level domain expertise, Project Magnet has resulted in a completely integrated pit-to-port solution that continues to provide many benefits to the Whyalla and South Australian communities.

VISION SYSTEMS WHAT YOU NEED TO KNOW

Christopher Chalifoux, International Applications Engineer, Teledyne DALSA

Vision systems are a primary consideration for any manufacturer who is looking to improve quality or automate production, but choosing systems that match your application and ownership requirements can be confusing.

ision systems can be thought of as computers with eyes that can identify, inspect and communicate critical information to eliminate costly errors, improve productivity and enhance customer satisfaction through the consistent delivery of quality products. Primarily used for online inspection, vision systems can perform complex or mundane repetitive tasks at high speed with high accuracy and high consistency. Errors or deviations in the manufacturing process are immediately detected and relayed, allowing control modifications to be made on the fly to reduce scrap and minimise expensive downtime. Vision systems are also deployed for non-inspection tasks, such as guiding robots to pick parts, place components, dispense liquids or weld seams. Vision systems come in all shapes and sizes to suit any application need, but they all have the same core elements. Every vision system has one or more image sensors that capture pictures for analysis and all include application software and processors that execute user-defined inspection programs or recipes. Additionally, all vision systems will provide some way of communicating results to complementary equipment for control

28 WHAT'S NEW IN PROCESS TECHNOLOGY - OCTOBER 2014

or operator monitoring. That said, it is important to know that there are significant and important differences between vision systems that make one more suitable than another for any given application. It is equally important to know and appreciate the importance of choosing the optimal sensor, lighting and optics for the job. Failure to do so may result in unexpected false rejects or, even worse, false positives. There are many variants of vision systems on the market, but for the purpose of this article we will classify them all into two categories - those with a single embedded sensor (also known as smart cameras) and those with one or more sensors attached (multicamera vision systems). The decision to use one or the other is dependent not only on the number of sensors needed, but also on a number of other factors including performance, ownership cost and the environment where the system needs to operate. Smart cameras, for example, are generally designed to tolerate harsh operating environments better than multicamera systems. Similarly, multicamera systems tend to cost less and deliver higher performance for more complex applications. Another way to differentiate the two classes of systems is to think in terms of

Vision systems

capabilities (such as pattern matching, feature finding, barcode/2D recognition, OCR) and can interface with complementary devices using standard factory protocols. If your needs are more complex and you are comfortable with programming, you might look for a more advanced software package that offers additional flexibility and control. In either case, make sure that the software you choose is available across vision system platforms in case you need to migrate due to changing inspection requirements.

Implementation factors to consider

Image sensor resolution

processing requirements. For many applications, such as in car manufacturing, it is desirable to have multiple independent points of inspection along the assembly line. Smart cameras are a good choice as they are self-contained and can be easily programmed to perform a specific task and modified if needed without affecting other inspections on the line. In this way processing is distributed across a number of cameras. Similarly, other parts of the production line may be better suited to a centralised processing approach. For example, it is not uncommon for final inspection of some assemblies to require 16 or 32 sensors. In this case, a multicamera system may be better suited as it is less costly and easier for the operator to interact with. Perhaps the most important consideration when selecting any vision system is software. The capabilities of the software must match the application, programming and runtime needs. If they don’t, you will find yourself investing more time and expense than you anticipated in trying to make the system conform to your expectations. If you are new to machine vision or if your application requirements are straightforward, you should select software that is easy to use (doesn’t require programming), includes core

www.ProcessOnline.com.au

Image sensors convert light collected from the part into electrical signals. These signals are digitised into an array of values called ‘pixels’, which are processed by the vision system during the inspection. Image sensors can be integrated into the system, such as in the case of a smart camera, or into a camera that attaches to the system. The resolution (precision) of the inspection depends in part on the number of physical pixels in the sensor. A standard VGA sensor has 640 x 480 physical pixels (width x height) and each physical pixel is about 7.4 microns square. From these numbers, resolution can be estimated for your real-world units. Image sensors used by vision systems are highly specialised, and hence more expensive than, say, a webcam. First, it is desirable to have square physical pixels. This makes measurement calculations easier and more precise. Second, the cameras can be triggered by the vision system to take a picture based on a part-in-place signal. Third, the cameras have sophisticated exposure and fast electronic shutters that can ‘freeze’ the motion of most parts as they move down the line. Image sensors are available in many different resolutions and interfaces to suit any application need. In many cases, multiple image sensors are deployed to inspect large parts or different surfaces of the same part.

Sensor lens selection Each sensor needs a lens that gathers light reflected (or transmitted) from the part being inspected to form an image on the sensor. The proper lens allows you to see the field of view (FOV) you want and to place the camera at a convenient working distance from the part. The working distance is approximately the distance from the front of the sensor to the part being inspected. A more exact definition takes into account the structure of the lens and the camera body. Consider this example: If a part to be inspected is 100 mm wide by 50 mm long, you would need an FOV that is slightly larger than 100 mm, assuming you can position the part within this FOV. In specifying the FOV you need to also consider the camera’s aspect ratio - the ratio of the width to length view. The sensors used with vision systems typically have a 4:3 aspect ratio, so the example 100 mm x 50 mm part would match the sensor dimension, but a 100 mm x 90 mm part would require a larger FOV to be seen in its entirety.

Vision systems

THE CAPABILITIES OF THE SOFTWARE MUST MATCH THE APPLICATION, PROGRAMMING AND RUNTIME NEEDS. IF THEY DON’T, YOU WILL FIND YOURSELF INVESTING MORE TIME AND EXPENSE THAN YOU ANTICIPATED IN TRYING TO MAKE THE SYSTEM CONFORM TO YOUR EXPECTATIONS. SELECTING THE PROPER LIGHTING REQUIRES SOME KNOWLEDGE AND EXPERIENCE THAT MOST SUPPLIERS CAN PROVIDE DURING APPLICATION EVALUATION.

Figure 1: Resolution affects quality. Left: Image taken with 640x480 image sensor. Right: Same image taken with 1600x1200 sensor.

From the FOV, working distance and the camera specifications, the focal length of the lens can be estimated. The focal length is a common way to specify lenses and is, in theory, the distance behind the lens where light rays ‘from infinity’ (parallel light rays) are brought to focus. Common focal lengths for lenses in machine vision are 9, 12, 16, 25, 35 and 55 mm. When the calculations are done, the estimated focal length will probably not exactly match any of these common values. The way around this is to pick a focal length that is close and then adjust the working distance to get the desired FOV. Most vision suppliers have tools that will help you calculate the closest lens to match your FOV and working distance. There are other important specifications for lenses, such as the amount and type of optical distortion the lens introduces and how closely the lens can focus.

Lighting source The human eye can see well over a wide range of lighting conditions, but a machine vision system is not as capable. You must therefore carefully light the part being inspected so that the vision system can clearly ‘see’ the features you wish to inspect. Ideally, the light should be regulated and constant so that the light changes seen by the vision system are due to changes in the parts being inspected and not changes in the light source. While some vision algorithms can tolerate some variation in light, a well-designed implementation will remove any uncertainty. When selecting a light source, the goal is to amplify the elements of the part that you want to inspect and attenuate elements that you don’t care about. Proper lighting makes inspection faster and more accurate, whereas poor lighting is a major cause of inspection failure. Generally it is recommended to avoid using ambient light, such as overhead light, as this can vary over time. Factory lights can beat, burn out, dim or get blocked. Similarly, if there are windows near the inspection station, outside light changes can have a negative effect on system robustness. Selecting the proper lighting requires some knowledge and experience that most suppliers can provide during application evaluation.

Predictable part presentation It is important to consider how parts will be presented to the vision system for inspection. If the part is not presented in a consistent way, you will not achieve the desired result. Therefore,

30 WHAT'S NEW IN PROCESS TECHNOLOGY - OCTOBER 2014

you will need to ensure that the surface of the part you want to inspect is facing the sensor at runtime. Next you will need to decide whether the part is to be inspected while in motion or stationary. If the part is moving, the motion will likely need to be ‘frozen’ by turning the light on briefly (strobing) or by using the high-speed electronic shutter feature of the sensor (standard on most industrial vision sensors). In this case you will need to provide a trigger to the sensor to let it know when to take a picture. The trigger is typically generated by a photoelectric sensor that detects the front edge of the part as it moves into the inspection area. If the part is stationary, for example indexed or positioned in front of the sensor by a robot, the sensor can be triggered to take a picture from a PLC or the robot itself. Finally, if you are inspecting parts at very high speed, you will likely need to optimise part positioning to reduce processing time. Keep in mind when designing your system that everything consumes processing bandwidth. So, when considering a vision system for high-speed inspection, you should try to determine which of your requirements are critical or just ‘nice to have’. Armed with knowledge, support and a reputable supplier, the cost of implementing vision solutions on the factory floor will be returned many times over through increased quality, production efficiency and scrap reduction.

The absolute position is recognised right after power-on, eliminating the need for jogging during initialisation of the robot arm. The safety settings of the latest generation of the company’s lightweight robots allow the robot arm to run in two operating modes; a normal and a reduced speed. A switch between safety settings during the robot’s operation is also possible. To achieve this, eight safety functions are monitored by the safety system: joint positions and speeds; TCP positions; orientation; speed and force; as well as the momentum and power of the robot. The settings can only be changed in a password-protected area. The UR Safety 3.0 safety system is certified by TÜV Nord and tested in accordance with EN ISO 13849:2008 PL d and EN ISO 10218-1:2011, Clause 5.4.3. Sixteen additional digital I/Os are available, which are easy to configure either as digital signals or as safety signals. The six-jointed, cost-efficient robot arms UR5 and UR10 are especially suited for small and medium-sized businesses, due to their light weight and their easy programming and user-friendly handling via touchpad.

CASE STUDY

Airport baggage receives an upgrade

It’s a scene that is repeated thousands of times daily, in airports all around the world. Collect the boarding pass. Drop the bag at the check-in counter. Proceed to the departure lounge, sometimes with time to spare and sometimes in a last- minute dash. Not so familiar to most travellers, though, is the technology that delivers baggage to the aircraft once the items disappear from view at the check-in point. Behind the scenes is a sophisticated system of conveyor lines, sortation, storage facilities and controls, all designed to ensure that each bag proceeds efficiently to the right aircraft at the right time. By improving these systems, terminal operators are able to increase capacity, cut costs and improve service to their customers. Keeping the conveyor lines rolling is clearly fundamental to the smooth running of the terminal. Consequently, choosing the most appropriate motors and drives to power the conveyors is a major requirement for any new system. As Qantas geared up for the end-of-year rush in 2013, Rainer Dinkelmann, Projects Manager at ICM Airport Technics Australia, oversaw the design and installation of such a baggage handling upgrade in one of the airport’s busiest departure terminals. ICM chose the latest version Movigear DAC drive system from SEW-Eurodrive for the upgrade, based on its power-saving features and reduced requirements for spares holding. Following the upgrade, the resulting increase in capacity has dramatically increased throughput at the terminal. This has contributed to facilitating the Qantas Group moving the operations of QantasLink from Terminal 2 to Terminal 3, within the existing building’s constraints. Key to the increased capacity was the installation of an automated bag store. Dinkelmann says that because of the new storage facilities, which can accommodate 200 bags at a time, capacity has been extended to over 10,000 bags per day. Bags that have been checked in well before flight time are held in the new automated bag store on ‘early arrival’ conveyor lanes. There are a number of ways of configuring automated bag stores at airports. “We use standard conveyors, with bags packed tightly together on storage lanes using smart technology,” says Dinkelmann. Prior to the upgrade, early arrival bags were manually removed from the conveyors, stored on a trolley, and then manually returned to the conveyors in time for departure. “It was a lot more handling,” says Dinkelmann. “In fact, each item would be handled three times instead of once.”

36 WHAT'S NEW IN PROCESS TECHNOLOGY - OCTOBER 2014

At the departure point the baggage is placed in unit load devices (ULDs), which are the aluminium containers familiar to passengers who watch their baggage brought out on trolleys and loaded in to the aircraft hold. The new storage facilities include an integrated batch building ball deck, consisting of a large array of steel balls that can rotate in any direction. The ball deck allows the ULDs to be positioned easily, both for storage and in readiness for assembly for the appropriate flight. This also allows preloading of batches of bags into ULDs well before flight departure. In addition to the automated bag store, the upgrade included a set of general improvements, with ICM’s team replacing the high-level control and SCADA systems. The supervisors can see how many bags are in the store for each flight and, while the store will automatically eject the bags according to their flight times, the supervisors can override the auto setting and call bags down in batches to specific destinations. This gives them far greater control and also means that the double handling of early bags is greatly reduced. In essence, this gives the supervisors the ability to tightly manage the baggage system and making the whole process far more efficient. With more than 10,000 bags being handled each day, reliability of the conveyor system is all important. To ke e p t h e co n ve y o rs rolling, ICM required around 100 of the Movigear DAC drive units. The design calculations confirmed a short payback period for the drives, which combine the motor, gears and drive electronics within a single unit and provide control communications via a standard AS-interface. This high level of integration resulted in fewer components being necessary for the conveyor system. In turn, this led to the reduction in spare parts requirements and a corresponding increase in the calculated availability figures. Designed for maximum energy efficiency, the selected drives provide up to 50% improvement over traditional systems. “Power consumption is very important for these projects. Power costs money. Both the calculations and results for the drives have been fantastic to date,” says Dinkelmann. “Delivery time was an important factor in the project too. SEW bettered their delivery time estimate, which helps immensely on tight project time lines.” A slightly longer and more detailed version of this article can be read online at: http://www.processonline.com.au/case_studies/69958 SEW-Eurodrive Pty Ltd www.sew-eurodrive.com.au

SMALL ROBOT FAMILY ABB has introduced the IRB 1200 robot family to address the needs of the material handling and machine tending industries for flexibility, ease of use, compactness and short cycle times while still maintaining large working envelopes. The IRB 1200â&#x20AC;&#x2122;s smooth surfaces make it easy to keep clean. Both electrical and air connections can be made to the robot via side ports or from beneath the base. In addition, an Ethernet port makes it easy to integrate with other equipment like the ABB Integrated Vision. These connections are routed internally on the robot from very close to the wrist flange, all the way to the foot, thus enhancing the compactness of the package. The IRB 1200 comes in two variants which can handle a wide range of applications and are cost effective due to commonality of parts. The 700 mm reach variant can carry a payload of up to 7 kg, while the longer reach 900 mm variant can carry up to 5 kg of payload. Both variants can be mounted at any angle. By design, the IRB 1200 has no offset in axis two. This innovation results in a longer stroke than other robots, meaning the IRB 1200 can be placed very close to the work piece and still be functional. One particular benefit of this long stroke is that it allows for a much more compact installation when the robot is mounted on the ceiling inside a small cell, such as in electronics machining or polishing applications.

EDDY CURRENT SENSOR The Micro-Epsilon eddyNCDT SGS 4701 eddy current sensor is suitable for measuring the thermal extension of high-frequency spindles in order to minimise positioning errors in machine tools. The spindle is at the heart of a machine tool and so plays a decisive role in the dimensional accuracy and surface quality of the respective workpiece. High speeds and the heat generated result in axial extension of the workpiece spindle and therefore to positioning error during finishing of the workpiece. The miniature sensor measures the thermal and centrifugal force extension of high-frequency spindles by measuring on the labyrinth ring. The measured values are fed into the CNC machine tool as correction values and compensate for any positioning errors. The miniature eddy current sensors have dimensions of 4.5 x 10 x 12 mm3 or 4 x 4 x 10 mm3 and can be integrated with the controller into the machine tool spindle. For ease of handling and in order to achieve maximum accuracy, the device is factory calibrated for ferromagnetic and non-ferromagnetic materials used by the customer. The temperature of the sensor is measured via the resistance of the eddy current coil for temperature compensation. This signal is also available to the user, which can eliminate the need for any additional temperaturesensing technology. Bestech Australia Pty Ltd www.bestech.com.au

bjects around you are increasingly being embedded with a myriad of sensors and actuators - from your roadway, to your body, to industrial processes. Kevin Ashton (from Proctor & Gamble) used the term â&#x20AC;&#x2DC;internet of thingsâ&#x20AC;&#x2122; to refer to everyday objects autonomously communicating with each other. There are incredible opportunities opening up in engineering and industry to apply these technologies and data to your work. When formerly inanimate objects can sense the environment and communicate, they become tools for discerning what is happening in remote environments and making decisions on the data. You are already probably aware of the tiny microcameras that you can swallow to view your gut to pick up sources of illness. Or cars that brake automatically when detecting an object ahead. The IoT will undoubtedly impact your life in the next decade - no matter whether you are a plumber, plant operator, R&D scientist or CEO of a blue-chip company. And today, the Internet of Things has finally come into its own. Technology costs have been steadily falling and the field is now enjoying wide support from the business community. Recent research has identified a number of key features of the growth of the IoT. Firstly, most organisations are well aware of the IoT, but investment is still slow, and new skills are required to unlock the full potential. In addition, cooperation between companies (including competing companies) is required to make it work, but consumers will soon be swamped with IoT products and services (even though many will not know it). The result will be that everyone from businesses to consumers will be overwhelmed with data from the IoT. According to McKinsey there are six types of applications that suit the IoT: behaviour tracking; situational awareness; mass data gathering for decision making; process optimisation; smart metering and the smart grid; and complex autonomous systems.

Sensors can track usage of equipment ranging from cars to the level of thrust of a jet engine to products moving through supply chains (using RFID). This behaviourtracking data is then relayed back to make decisions on such things as fees to charge for usage of a jet engine, or instructions to adjust shipments of goods. Data from sensors can indicate soil moisture, ocean currents, weather, rain, traffic intensity or intruders in a particular zone. Masses of sensors can also gather data - for example for oil and gas, or mining exploration (to locate high-grade deposits) - and feed this back for mapping, analysis, and decision making. As for process optimisation, we have been monitoring data from instrumentation for years, but the lowering cost and smaller size makes for even better process control and optimisation of flow, level, temperature and pressure - and more effective ways of processing previously inaccessible or slowchanging data. Smart meters are also increasingly being used to provide details of energy usage and real-time costs to consumers and power companies. Application of sensors and actuators to the car industry means that we are now seeing complex automation systems in which automatic braking is now available - and eventually self-driving cars, perhaps allowing us to cut down on the million deaths per year due to car accidents. These technologies are not pie in the sky - they are being rolled out today. See if you can apply them in your next project. *Steve Mackay, PhD CPEng, has worked mainly in the industrial automation and data communications fields across the world for the past 30 years and is currently technical director with worldwide engineering education business IDC Technologies (www.idc-online.com).
