8.3 Pneumatic tape cutter

8.3.1 Structure and function of the pneumatic tape cutter

The tapes guided into the slot (3) of the tape cutter via the empty tape duct (Pos.3 in Fig. 8.3 - 1).

The tape cutter is based on a horizontal frame (Pos.1) with a fixed cutting blade(6) and a moving

cutting blade that is driven by two pneumatic cylinders (Pos. 2). With every in and out movement,

the device cuts off the tape.

Proximity switches (Pos. 5) signal the position of the pneumatic cylinder pistons, and thus the

cutting blade. The electronic control unit (4) thus registers, for example, that a component that

remained in the tape was not cut. Cutting only takes place during placement. For operational

safety reasons, the tape cutter is integrated into the emergency stop circuit.

The pneumatic tape cutter is fixed on the frame of the docking unit with four screws and this, to-

gether with the empty tape duct is a complete unit.

The Tape cutter is activated when the gantry is moving to the placement position. Alternating one

of the cylinders start to front position. The signal ’in front’ from the first cylinder start the cylinder

on the other side. Both signals ’blade in front position’ trigger control unit to withdraw both cylin-

ders at the same time.

8.3.2 Jumper setting on the control unit at the tape cutter

The jumper for the CAN bus addressing must be set according to the corresponding location in

the machine.

Please Note:

The pneumatic hose of the actuator cylinders at both side are crossed. This is due to the electrical

actuator of the 5/2 way valves were mounted with the nose side facing the outer side of the cutter

unit. (At HS machines, the right actuator is mounted with the tube facing the inner side and there-

fore the hoses are NOT crossed).
