5.9.3 Mode of operation
The nozzles are seated in nozzle garages and are held in place by a movable locking plate. The
locking plate can be moved 12 mm by a pneumatic cylinder. All the nozzles are either clamped or
released, depending on the position of the plate. The default position of the locking plate, i.e. if
there is no nozzle change in progress, is "closed". 5
There is a positioning fiducial for position detection on each magazine of the nozzle changer. The
magazine locations are identified by numbers 1 to 5 on the nozzle changer. The nozzle garages
in the magazines are numbered consecutively from 1 to 6 (see Fig. 5.9 - 2
). 5
PLEASE NOTE 5
Special magazines are available upon request (contact Siemens PL EA 1E for details) and will be
numbered differently. 5
Picking up a nozzle 5
– The collect&place head Z axis moves down.
– The locking plate (item 2 in Fig. 5.9 - 2
) opens and releases the nozzle garages.
– The nozzle is picked up by the sleeve of the collect&place head.
– The Z axis moves up.
Setting down a nozzle 5
– The locking plate (item 2 in Fig. 5.9 - 2) opens and releases the nozzle garages.
– The collect&place head Z axis moves down and sets the nozzle down.
– The locking plate closes.
– The collect&place head Z axis moves up.
Discarding defective nozzles 5
– The collect&place head Z axis moves down 14 mm towards the discarding device (item 4 or 5
in Fig. 5.9 - 1
) and thus moves the defective nozzle into the hole in the discarding device.
– The Z axis moves up again and the nozzle is stripped from the sleeve by spring wires.
– The nozzle drops into the container (item 6 in Fig. 5.9 - 1
).

5.9.4 Notes on operation
Å
You can fill the nozzle magazine with different types of nozzles from the same family, e.g. fill
no. 8 magazines with nozzle types 821, 822, 823, etc., and no. 9 magazines with nozzle types
911, 914, etc.
PLEASE NOTE 5
Fill the magazines off the machine and always replace complete magazines. 5
Å Open the locking plate and place the nozzles in the nozzle garages.
Å Close the locking plate so that the nozzles cannot drop out of the magazines.
CAUTION 5
Before you fill magazine, make sure that all the nozzles on the collect&place head have been
returned to their magazines. 5
Å See the UNIX line computer operating instructions for programming the nozzle changers on
the line computer.
PLEASE NOTE 5
Å Do not allow components to drop onto the magazines. If they do, they could jam the locking
plate.
Å Do not allow components to drop onto free feeder module locations because they will stick to
the magnetic bar. Production may have to be interrupted if the feeder modules are not placed
on the component table correctly. You should therefore regularly clean the magazines and free
locations.
