VACUUM

The atmosphere and its effects on the vacuum technology The (ambient) air pressure depends on the altitude of the place where it is measured. As illustrated here beside, the pressure at sea level is 1013 mbar. At an altitude of 600 m the air pressure is 938 mbar. At an altitude of 2000 m the air pressure drops to only 763 mbar

Vacuum - Basics The definition of vacuum Vacuum is the term for air pressures which lie below normal atmospheric pressure. The vacuum values used depend on the specific application.

For vacuum handling, relatively low vacuum values are sufficient. The values for vacuum lie in the range between 1 mbar and atmospheric pressure (1013 mbar).

This pressure drop naturally affects the use of vacuum. As the air pressure drops with increasing altitude, the maximum pressure difference which can be achieved also drops, which means that the maximum possible holding force of a vacuum gripper is also reduced. For each 100 m height increase, the air pressure drops by about 12,5 mbar. A vacuum generator which achieves a vacuum of 80% (-800 mbar) at sea level can thus generate a vacuum of only -610 mbar (80 % of the ambient air pressure of 763 mbar) at an altitude of 2000 m. The maximum possible holding force of a vacuum gripper decreases proportionally. Operation at sea level is thus the ideal situation.

Important: In the catalogue, the holding forces of the suction pads are always specified at the most economical vacuum level of -600 mbar!

Holding force Energy required

Widely used typical vacuum values - for air-tight surfaces (e.g. metals, plastics, etc.): from 60% to 80% vacuum (from -600 to -800 mbar). - for porous materials (e.g. cardboard, chipboard and MDF sheets, etc.): from 20% to 40% vacuum (from -200 to -400 mbar); in this range the necessary holding force is generated by increasing the suction rate of the vacuum generator and by increasing the effective area of the vacuum grippers.

blow-off valve 2/2-way NC (compressed air)

control valve 2/2 N.O. (compressed air)

The energy required for the generation of vacuum increases much faster than the vacuum value which is achieved. When increasing the vacuum from -600 mbar to -900 mbar, the holding force is increased by factor 1,5 while the evacuation time and the energy needed to achieve this value increases by a factor of 3! It is thus clear that the maximum achievable vacuum value is not he optimum value for vacuum handling tasks.

VACUUM

Specification as a relative value. In the vacuum handling sector, the vacuum is specified in the form of a relative value, i.e. referred to the ambient pressure. These vacuum values always have a negative sign, because the ambient pressure is used as the reference point, which is defined as 0 mbar.

VACUUM

A vacuum blower - principle function

Functioning of the main components

In a vacuum pump, the rotating blades (A) draw air in from the outside and accelerate and compress it. This means that kinetic energy is transferred from the impeller to the air. Since the air is pulled in by the blades, a vacuum is created at the inlet side (B). The compressed air leaves the pump through the outlet (C). Vacuum pumps have a high suction capacity, but the vacuum value is not as good as those generated by ejectors and vacuum pumps.

how does a suction pad work? When the ambient pressure (atmospheric pressure) is higher than the pressure between the suction pad and the workpiece, the ambient air pressure presses the suction pad against the workpiece.

Principle of operation of a vacuum blower

This pressure difference is achieved by connecting the suction pad to a vacuum generator, which evacuates the air from the space between the pad and the workpiece. If the suction pad is in contact to the surface of the workpiece no air can enter it from the sides and a vacuum is generated. The holding force of the suction pads increases proportionally to the difference between the ambient pressure and the pressure inside the pad.

VACUUM

a vacuum ejector - principle function Ejectors generate a vacuum on the basis of the so-called Venturi principle. Compressed air enters to the ejector at A and flows through the nozzle B. This results in a pressure drop (vacuum) just behind the tip of the nozzle and air is drawn in through the vacuum inlet D.

This air, and the compressed air passing through the nozzle, leaves the ejector through the silencer C.

Important: The suction capacity of all vacuum generators is specified in l/min or m3/h. These specifications refer to an ambient pressure of 1000 mbar and to an ambient temperature of 20 °C.

Compact ejectors The compact ejectors are also single-stage ejectors, but they also have two valves for direct control of functions “grip” and “blow off”. In addition, these ejectors are also available with vacuum switches or system monitoring and regulation. The combination of the “grip” valve and a vacuum switch permits implementation of an automatic air-saving function which ensures that compressed air is consumed only when the vacuum measured by the vacuum switch drops below a value defined by the customer.

Suction with the pad not covered

The advantages of compact ejectors are their compact design, which results in lower space requirements and a lower weight, combined with the many integrated functions.

Evacuation with a workpiece attached

Calculation examples System design - the procedure In this section the design procedure is described for a complete system step by step. The below exercise is based on a typical design example.

Multi stage ejectors Besides single-stage ejectors, there are ejectors which have several Venturi nozzles arranged in series. These multi-stage ejectors have a higher suction capacity than single-stage ejectors.

Ext. vacuum switch signal

2. Suction pads 1. Calculation of the forces Flowchart for system design

a vacuum pump - principle function A vacuum pump contains an eccentrically mounted impeller with vanes which seal off parts of the cylindrical space in which the impeller turns. These vanes are pressed against the walls of the internal space by centrifugal force. Due to the eccentric mounting of the impeller, the spaces between the vanes have different volumes. The large volume of space B permits the incoming air to expand, which results in a pressure drop. In space C the volume is smaller and the air in this space is compressed. Pumps generate a very high vacuum and provide, depending on the type, suction capacities which can be very high.

The calculations in the example are based on the following data: Principle of operation of a vacuum pump Workpiece

portal transfer unit 8 bar 24 V DC horizontal - horizontal X and Y axes: 5 m/s2 Z axis: 5 m/s2 30 s for picking up: <1s for releasing: <1s

Calculating the weight of the workpiece

Vacuum switches - principle function Vacuum switches operate mechanically, pneumatically or electronically. In the mechanical and pneumatic versions, a diaphragm reacts to changes in the air pressure and actuates a mechanical switch or a valve. In the electronic version, the pressure is measured by means of a piezo-resistive sensor and an electrical, digital (on/off) output signal is generated. It is also possible to generate an electrical analogue signal which is proportional to the measured pressure.

Handling system

steel sheets, stacked on a pallet smooth, flat, dry length: max.2500 mm width: max.1250 mm thickness: max.2,5 mm weight: circa 60 kg

Vacuum switches can be used to monitor and control processes. Most vacuum switches permit adjustment of the switching point, and some also permit adjustment of the hysteresis.

For all subsequent calculations, it is important to know the mass of the workpiece to be handled. This can be calculated with the following formula:

Mass m [kg ]:m = L x B x H x ρ L = length [m] B = width [m] H = height [m] ρ = density [kg/m3] Example:

Forces - how high forces do the suction pads have to support? Important: In the following simplified representations of the load cases I, II and III, the worst case with the highest theoretical holding force must always be used for the subsequent calculations.

Load case i: horizontal suction pads, vertical force

The suction pads are placed on a horizontal workpiece which is to be lifted vertically.

The suction pads are normally selected on the basis of the following criteria: Operating conditions: the operating conditions (single or multiple shift operation, expected lifetime, aggressive surroundings, temperature etc.) at the point of use are decisive for the selection of the suction pads.

Example: In this example, where steel sheets are to be handled, we will use the flat suction pads, Mod. VTCF in NBR. This is the best and most efficient solution for the handling of smooth, flat workpieces.

FTH = 61,33 x (9,81 +5)x 1,5 FTH = 1363 N

Example: For medium sized (2500 x 1250 mm) steel sheets, normally 6 to 8 suction pads would be used. The most important criterion for deciding the number of suction pads in this example, is the flexing of the steel sheet during transport. Calculation of the suction force FS [N]

According to the Technical Data as shown on page 9 for Series VTCF, 8 pcs. of suction pads Mod. VTCF-800N are needed with a suction force of 260 N each.

In this example we decide to use 6 pcs. of suction pads Mod. VTCF-950N since this number is sufficient and helps to keep the costs down.

Normally, the manner in which the suction pads are mounted is defined to meet the customer’s needs. However, there may be special reasons which make a specific mounting element mandatory in certain cases:

We decide to use: Spring plunger Mod. NPM-FM-1/4-75 We need the largest possible stroke to cope with the hanging ends of the steel sheets. The 1/4 thread is needed for connection to the flexible nipple.

Uneven or sloping surfaces The suction pad must be able to adapt itself to the slope: » flexible nipple NPF

Flexible nipple Mod. NPF Optimum flexibility for inclined workpiece surfaces.

Different heights or thicknesses The suction pads must be spring-mounted in order to compensate for varying heights: » spring plunger

The suction pads are placed on a vertical or horizontal workpiece which is to be moved vertically or turned to the other orientation.

How to select the suction pads

In order to determine the necessary holding forces, the above mass calculation is needed. In addition, the suction pads must be capable of handling the acceleration forces which, in a fully automatic system, are by no means negligible. In order to simplify the calculation, the three most important and most frequent load cases are shown graphically and described below.

Check valves Mod. VNV These are used on vacuum gripper systems containing multiple suction pads in order to shut off indivual suction pads which are not covered by the workpiece, (when handling work pieces of different sizes). Note: When selecting the mounting elements, please make sure that these can be screwed onto the suction pads, i.e. that they have threads of the same size. Also note the load-carrying capacities of the mounting elements.

Selection of vacuum hoses The size of the vacuum hose should match the suction pads which are used. For selection of suitable tube dimension, see recommendations under Technical Data.

FTH = 61,33 x (9,81 +5/0,5)x 1,5 FTH = 1822 N

Example: For exampe, from the table with Technical Data we choose a TRN 8/6 hose in polyammide.

For the example used for this description, load case III can be ignored, since the workpieces are to be handled only in a horizontal orientation.

Comparison: A comparison of the figures for load cases I and II results, in this example, in a maximum value for FTH =1822 N in load case II, and this value is therefore used for further design calculations.

Universal suction pads in NBR or Silicone, ideal for a wide range of applications. Diameters from 3.5 to 95 mm with thread size M3, M5, G1/8, G1/4, both male and female.

Calculation of the required suction rate V [M3/H, L/MIN]

V n VS

= n x VS = number of suction pads = required suction rate for a single suction pad [m3/h, l/min]

The suction rate values of the different vacuum generators can be found in the table Technical Data.

Example:

V = 6 x 16,6 V = 99,6 l/min

» Wide range of diameters, all available in materials NBR or Silicone. » Low profile, with reduced intrinsic volume which enables short cycle times and/or the use of smaller vacuum generators. » Compact design for good resistance towards transversal forces at high accelerations, thus suitable for applications with fast movements. » Supports on the bottom of the suction pad which reduce the risk for permanent deformation of thin-walled objects.

Required suction rate as a function of the suction pad diameter

Suction pad Ø up to 20 mm up to 40 mm up to 60 mm up to 90 mm up to 120 mm

Required suction rate Vs 0,17 m3/h 0,35 m3/h 0,5 m3/h 0,75 m3/h 1 m3/h

2,83 l/min 5,83 l/min 8,3 l/min 12,7 l/min 16,6 l/min

Note: The indicated values apply to all types of vacuum generators. The recommended suction rate is for a single suction pad and is valid only for smooth, air-tight surfaces. For porous surfaces we recommend the execution of a suitable test before selection of the vacuum generator.

We choose a compact ejector Mod. VEC-20 with a suction rate of 116 l/min.

Selection of vacuum switches Vacuum switches and pressure gauges are normally selected on the basis of the functions required in the application and on the switching frequency. The following functions are available: - adjustable switching point - fixed or adjustable hysteresis - digital and/or analog output signals - status LED - display with keypad - connection with M5 Female thread, G1/8 Male flange or plug-in tube Example: - vacuum switch SWD-V00-PA with digital display, adjustable switching point and adjustable hysteresis (already integrated in the compact ejector) - pressure gauge.

The flat suction pads Series VTCF have a very robust and wear resistant design and consist of a nipple and rubber part. On suction pads with diameter up to 50 mm, the nipples are inserted directly into the rubber part. From diameter 60 mm and up, a mounting plate is vulkanised into the rubber part to which the nipple should be mounted. The suction pads can also be ordered separately without nipples as spare parts. The suction pads Series VTCF are generally used for handling of objects with smooth or slightly curved surfaces such as sheets of different materials, extruded profiles, cardboard boxes, plastic components, wood panels etc.

Applications - Handling of flat parts with smooth or slightly rough surfaces - Version in silicone for the handling of parts at high temperatures.

General data Selection of the vacuum switches and pressure gauges Even if you are confident that the results of the system-design work are correct, you should still carry out tests with original workpieces to be on the safe side. However, the theoretical system design will give you a good idea of the general parameters for the intended application.

Technical information

SUCTION PAD VTCN male thread

When designing a vacuum circuit and selecting suitable suction pads it is necessary to follow certain calculations to select each individual component in a correct way. Listed below is a summary of the most common data to take into consideration.

G1 dn

LG1

SW1

Lateral force The measured value in N at a vacuum of -0,6 bar on a dry or oily, flat and smooth workpiece surface. These values do not include a safety factor.

Minimum workpiece curvature radius This specifies the minimum radius at which the workpiece can be gripped securely by the suction pad.

Theoretical suction force Theoretical force (N) at a -0,6 bar measured at sea level. Since this is a theoretical value, it is necessary to reduce this value by adding a safety factor to compensate for friction or loss of vacuum, depending on the application (from rough workpiece surface or porous material etc.)

Internal volume This is used to calculate the total volume of the gripper system. With this value, it is also possible to calculate the evacuation time

Suction pad stroke This is the lifting effect which occurs during evacuation of a bellows type suction pad.

Selection and configuration Planning check-list for selection of suction pads What are the workpiece dimensions and weight?

This is important data for the suction force calculation and to establish the required suction force and number of suction pads, (see technical information).

How is the workpiece surface (rough, structured, smooth)?

It determines the kind of suction pad (material, shape, dimensions).

Could the workpiece be dirty? If so, what kind of dirt?

This is important information to select the suction pad dimensioning (see technical information) and also for the design of the dust filter.

What is the highest workpiece temperature?

Temperature is important to select the suction pad material. At temperatures above 70°C the use of silicone versions should be considered.

Is an accurate gripping/placing/positionining required? What is the cycle time?

Determines the structure, the type and the version of the suction pad. This data is important for the dimensioning and plays a part in the calculations (for instance the vacuum generator suction capacity calculation); (see the technical information).

What is the maximum acceleration during handling?

This is important for the dimensioning and design of the suction force, together with the related calculations (for instance the suction capacity and the moment of inertia); (see the technical information).

Which kind of handling is needed (moving, slewing, turning over)?

This data is important to establish the dimension and the suction force calculation.

Principle function: Compact ejectors Series VEC-…R.. are equipped with an optional automatic air-saving system. This air-saving system consists of a set of cables with an integrated control circuit. When gripping an object, (vacuum on), the ejector remains active until a preset vacuum value is reached. Once reached the preset vacuum value, the ejector is shut OFF. The ejector remains OFF as long as the vacuum value lies within the set hysteresis range, (the ejector consumes no compressed air in this phase). If the vacuum level drops (e.g. due to a leakage in the vacuum system) below the preset limit value, the ejector is re-activated (vacuum on) by the electronic control circuit until the preset vacuum value is reached again. NB The compact ejectors with air-saving system are delivered complete with connectors and cables. Applications example: calculation of air consumption - comparison
