APPARATUS AND METHOD FOR MOVING FRAMEWORKS BETWEEN WORKSTATIONS

摘要

An apparatus and a method for moving frameworks such as window frames or sashes from a plastic frame welding machine to a work station for further processing of the frameworks are disclosed. Two tracks are mounted at an elevated position so they extend horizontally from the welding machine to the workstation and an arm assembly is mounted for movement along each track. Preferably each arm assembly has gripping devices arranged one above the other each capable of releasably engaging and gripping one of the frameworks. An actuator is provided to move each arm assembly along its track from a position where the arm assembly can engage the frameworks when they are in the welding machine and then move them to a position where the grippers can grip the frameworks at the workstation.
