9.4.2 Structure and Function of the Pneumatic Tape Cutter
9-9: Pneumatic tape 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.

9.4.3 Function Test for Tape Cutter in the Machine
Since the noise of the tape cutter does not indicate whether the cutting procedure is being performed
correctly, the function of the tape cutter can only be checked by inserting a piece of paper with the
relevant length into the cutting channel.
X To prepare the test, use an adhesive strip to attach a sheet of DIN A4 paper lengthwise into the
empty tape duct.
X Now start the SITEST menu Component Table and activate the option "Actuate tape cutter".
X You can then examine the cutting quality on the sheet of paper.

9.4.5 Empty Tape Duct
The empty tape duct acts as a base for further modules:
The removable nozzle reject container (3)
The installation surface (5) for the C&P nozzle changer
The nozzle stripping unit (4)
NOTE:
For jumper setting details, refer to the service manual for the respective machine.

5. assembly surface for the nozzle changer
The empty tape duct receives empty tapes from
the feeders at the inlet gap (1) and guides these
from the outlet gap (2) to the cutting position of the
pneumatic cutter. This is where the tape is cut up
and falls down the waste slide, into the component
trolley waste tape container.
The empty tape duct is fixed to the pneumatic tape
cutter with four screws.
