Self contained drum dumping and hot melt holding tank and method of unloading, melting and dispensing a slug of hot melt material

摘要

A method and device for quickly, easily, efficiently and safely dispensing hot melt from a container includes a dumper for receiving a container of hot melt. The dumper has removable smooth inner sheeting for receiving and holding canisters of different materials. The dumper has a heater heated by overlapping conducting coils for heating the hot melt in the container. The dumper receives the hot melt container at floor level and thereafter is actuated to move the dumper over and about a hopper to invert the container above the hopper. Additionally, the dumper forms a hermetic seal about the container and the hopper for firmly holding the container within the dumper to allow the hopper and the bottom of the container to be subjected to a controlled atmosphere. In operation, the bottom of the container may be punctured and an inert gas inserted within the dumper, and into the container under a relatively low pressure to force the hot melt slug from the container upon minimal heating of the sides of the container. After the slug of hot melt material is removed from the container and in the hopper of the processing machine, the dumper is returned to its level at the floor and the empty container safely removed.
