9.4 Pneumatic Tape Cutter
9.4.1 Overview of Pneumatic Cutter with Empty Tape Duct
The pneumatic cutter is fixed to the machine frame with four screws and forms a unit with the empty tape
duct. It separates plastic, aluminum and paper tapes up to a maximum pocket depth of 25 mm. The tape
clippings fall down the waste slide, into the waste tape container of the component trolley.
The empty tape duct is designed to cover the cutting edges of the cutter (to avoid risk of injury), to guide
the empty component tapes to the cutter, to integrate the component reject container and accommodate
the C&P12 nozzle changer.
NOTE:
The D4 machine is used as an example to describe the pneumatic cutter.

Legend
The empty tape duct guides the empty tapes through the opening (3) in the cutter.
The cutter is based on a horizontal frame (1) with a fixed cutting edge and a flexible blade, which is
moved by two short-stroke cylinders (2). At each forwards movement, the device cuts off the tape..
The proximity switch (5) signals the position of the short-stroke cylinder pistons and therefore of the
cutter blade. The control electronics (4) (under the cutter) register, for example, any components in the
tape which have not been cut. Cutting is only performed during the placement procedure. For operational
safety reasons, the tape cutter is integrated into the emergency stop circuit.
The tape cutter is activated when the gantry is moving to the placement position. Alternating one of the
cylinders start to front position. Once the first cylinder reaches the front position, the second cylinder is
started. Both signals ’blade in front position’ trigger control unit to withdraw both cylinders at the same
time.

NOTE:
The cutter can be removed within about 15 minutes for service purposes. For detailed
information about dismantling, refer to the service manual.
