7.1.2.3 Position of the nozzle changers for the C&P12 head on the X2 machine
1 or 2 nozzle changers may be installed at locations 1 and 3 for the 12 segment Collect&Place
head (items 1 and 2 in Fig. 7.1 - 13
). A nozzle changer may be installed at locations 2 and 4. This
gives a total capacity of 6 nozzle changers with 30 magazines and a total of 360 nozzle holders.

7.1.2.5 Assembly
"Row 1" nozzle changers (see Figs. 7.1 - 11, 7.1 - 12 and 7.1 - 13) are each fixed to the component
trolley docking unit. There is an additional assembly kit for the "row 2" nozzle changer. This kit
consists of the take-off device and the nozzle reject bin (see section 7.1.2.10
).

7.1.2.6 Description of the functions
The nozzles are seated in nozzle holders and are held in place by a movable locking plate.
A pneumatic cylinder moves the locking plate 6 mm. All the nozzles are either clamped or re-
leased, depending on the position of the locking plate. The default position of the locking plate,
i.e. if there is no nozzle change in progress, is "closed".
Every magazine of the nozzle changer has a positioning fiducial for position detection. The mag-
azine locations are numbered consecutively from 1 - 5 for the "row 1" nozzle changers and from
6 - 10 for the "row 2" (see Figs. 7.1 - 11
, 7.1 - 12 and 7.1 - 13). The 12 nozzle garages in the mag-
azines are also numbered consecutively (see Fig. 7.1 - 15
).
PLEASE NOTE 7
Special magazines are available upon request (contact SIEMENS A&D for details) and will be
numbered differently.
Picking up a nozzle 7
– The Collect&Place head Z axis moves down.
– The locking plate (item 2 in Fig. 7.1 - 15
) opens and releases the nozzles.
– The nozzle is picked up by the sleeve of the Collect&Place head.
– The Z axis moves up.
Setting down a nozzle 7
– The locking plate (item 2 in Fig. 7.1 - 15) opens and releases the nozzles.
– 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 7
– The Collect&Place head Z axis moves down 14 mm towards the discarding device (item 4 in
Figs. 7.1 - 11
, 7.1 - 12 and 7.1 - 13) 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 reject bin.
