Conveyors 14-3
The part enters the dispense zone.
Stop pins in the dispense zone block the conveyor path to stop the part. A lift table underneath the heating
plate rises up to the part. Tooling on the conveyor rails hold the part in place during the dispensing
process.
The second part loaded into the pre-dispense zone.
While dispensing is being performed on the first part in the dispense zone, a second part can enter the pre-
dispense zone.
The part moves out of dispense zone.
Once dispensing is complete, the stop pins withdraw, the lift table descends or the clamp bar releases,
after which the part is conveyed into the post-dispense zone, to a downstream machine, or to an unloader.
The part enters the post-dispense zone.
Stop pins block the conveyor path, stopping the part. If the system is so configured, a lift table or clamp
bar rises to hold the part in place, continuing to heat it if necessary. The dispenser sends a “Ready”
message to the conveyor, after which the second part is conveyed to the dispense zone.
Conveyor Maintenance
Routine conveyor maintenance is essential for optimal system performance. To prevent problems with the
conveyor rails or belt, or with part sensors, follow the basic procedures below on a regular basis. These
procedures may be performed by either an operator or a service technician.
WARNING! Before performing the following maintenance procedures, either press the
EMO button or turn the Main Circuit Breaker OFF (0).
CAUTION! These procedures should be performed only by Asymtek-trained
personnel.
Clean the Part Sensors
Use an air gun or air blower attachment to blow off dust or debris that may have settled upon the part
sensors. You may also use a dry cloth to wipe the sensors, if preferred. Clean sensors work better and last
longer than dirty ones. If application includes the use of thermal grease, do not use an air blower
attachment to clean the part sensors. Use a soft cloth to remove dust and debris.
Check the Conveyor Rails and Belts
Make sure that the conveyor rails are in good working condition by testing them before each production
run. Move the conveyor rail forward and backwards. If it does not respond, see Table 14-1. Check the
conveyor belt for cracks or splits. Notify an Asymtek service technician immediately if you notice a
cracked or broken belt. Use an air gun or air blower attachment to remove any dust or debris that may
have settled on the conveyor rails and belts.

NOTE If a conveyor belt or rail needs to be replaced, consult the dispensing system Installation
and Service Manual for removal and replacement instructions, or contact Asymtek
Technical Support.
