Information/Introduction

This specific information will allow for a quicker and more efficient action on the machinery. - Duplicate copies of this instruction handbook can be obtained by quoting the “serial number” of the machinery. Maintenance on the machinery must be compulsorily carried out by authorized staff, only. NOTE: "RIGHT" and "LEFT" indications refer to the operator positioned as defined in the herewith enclosed "Operatorís Work Station" lay-out.

1.4 Description The feeding device is a machine to be attached to vertical band saws in order to obtain the steady feed of the material to be cut. The feed is obtained thanks to a power-driven roller which, due to the contact, drives and transmits the motion to the workpiece to be cut up. A roller fence with appropriate length is essential to define the size of the cut up workpiece, ensure the workpiece stability while it is being cut and allow to apply the force for the feed. The drive system comprises a motor coupled with a continuous speed variator, which is keyed directly to the reduction unit that is in turn mated with the drive roller. All the machine is enclosed in a robust safety casing made of sheet steel, which also features a baffle board as a hand guard for the handling lever. Model supplied with spring The contact force exerted between the feeding device and the workpiece is given by the load of a spring located lengthwise in relation to the feeding device. The feeding device is engaged to and disengaged from the workpiece by the operator. He acts on a lever which is integral with the head of the feeding device itself. A pivot to lock in place ensures the permanent stop in the disengaged positioning. Pneumatic model The contact force exerted between the feeding device and the workpiece depends on the action of a double acting pneumatic cylinder located lengthwise in relation to the feeding device. The feeding device is engaged to and released from the workpiece by means of the double acting cylinder. For all the models the feeding roller can be either of rubber or of toothed steel.

1.5

Uses of the machinery for its intended purposes

The machinery was designed and constructed to be applied onto the work table of the stationary-table vertical band saws. This machinery must be fitted by pre-setting the work table as described in the chapter relating to the installation contained in this manual and by making use of the fitting material the machinery comes supplied with. The machinery is apt to feed workpieces of a wooden material featuring at least two parallel, opposed surfaces: the roller fence and the feeding roller will refer on them. The people involved in its design stage considered its use in a working environment with the specifications of temperature, moisture and lighting provided for by the Decree Law No. 626/1994 Title II.

1.6

Uses falling outside the intended purposes

Its use with materials other than wood or its by-products is not envisaged. You also fall outside its intended purposes when you use a non-homogeneous material which does not feature two parallel, opposed faces the roller fence and the feeding roller can refer on

â&#x2DC;&#x17E;

Connection: First make sure that the voltage shown on the rating plate fixed on the machine exactly matches the mains voltage, then connect the feeding device to the electrical system of the band saw by means of a cable of appropriate dimensions and protected by a reinforced-type flexible sheath. In order to safeguard the motor, the saw electrical system must be supplied with an overcurrent protection device (thermal sensor) complying with the technical provisions governing accidental startings and the electrocution protection. Ascertain whether the short-circuit current intensity envisaged at the connecting terminals of the mains switch is compatible with its cut-off power. Hook up the contacts of the safety electrical interlock switch relating to the door allowing to gain access to the internal parts so as to cut out the power supply to the feeding device when the access door is open and so as to avoid its automatic restart as soon as the access door is closed (Short-circuit in compliance with CEI 44-5 standards).

â&#x2DC;&#x17E;

Installation/Connections

Pneumatic feeding device The feeding device with pneumatic opening/closing comes supplied with a safety solenoid valve: In the event of a power failure or of an emergency, the latter opens the feeding device or disengages it from the workpiece, unless there is a failure in the compressed air supply. Connect the power supply of the safety solenoid valve by withdrawing power from a power supply source inside the band saw control unit. This source must provide for the power supply cut-out as a result of a stop or of an emergency command. See the wiring diagram of the pneumatic feeding device for the power supply specifications of the safety solenoid valve. See the wiring diagram of the band saw to select the exact connection location for the power supply of the solenoid valve itself.

CAUTION!!! Make some functional tests before using the machinery.

Position the opening command lever so that it might be easily controlled, either directly or by means of the workpiece to be machined. You must avoid approaching dangerous areas such as the blade or taking unstable or twisted positions. This lever is usually fitted on one side of the roller fence, at the material entry section, so that the workpiece might operate it directly, while it is being inserted.

4.4

Pneumatic connection

Connect the compressed air supply line with the entry section of the FilterRegulator Lubricator (FR+L) assembly by means of a quick coupling for 1/2" tubes. The supply line must be fitted with an ON-OFF valve so that the machinery might be insulated from the supply line in the event of maintenance work or operations on the feeding device which are not directly related to its standard use.
