ABSTRACT:
One or more hot melt tanks are each periodically supplied by an air conduit which automatically transfers pellets from a storage container. A transducer assembly, positionable in the container, includes a vacuum transducer for the pick up of glue pellets for transfer via the air conduit. A vibrator imparts motion to the pellets to prevent bridging of same. Each hot melt tank includes a level switch with a probe which provides a signal to a control panel having relays which in turn actuate solenoid valves for the delivery of a pressurized air flow to one or more vacuum transducers. A portion of the pressurized air flow is bled off for supplying the vibrator in place on a base of the transducer assembly.
