An optional purge station can be used to collect the purged adhesive. Parame-
ters are set up to centre the needle in the wiper target. The needle is fed into
the purge station and purging commences when the start purge button is
selected, and continues until the stop purge button is selected. If a purge station
isn’t used, purging takes place on a suitable area on the product.

OVERVIEW
Chapter Issue 2, Aug 14 Technical Reference Manual 38.5
Operation Regulated air is supplied to the rear of the syringe, forcing an internal plunger
to compress the adhesive. The auger body fills with adhesive and the auger
valve screw (Archimedes screw) is rotated, providing a stirring motion that
‘works’ the adhesive; this action disperses any air bubbles that may be present.
Figure 38-2 Exploded View of the Dispense Mechanism
The unit can be programmed to purge the contents of the syringe, ensuring
consistency, prior to a production run. Externally, a consumable level sensor
detects the level of the adhesive in the syringe and warns the operator when
the level is low. A laser can be programmed to take height readings across the
top surface of the product; the information gained, is used to adjust the dispense
height, thereby increasing the consistency during the dispense cycle.
For detailed set up and operation procedures refer to manual, Stinger, a guide
to adhesive dot dispensing - Part Number 198825.
