IMPROVED CONVEYOR BELT TAKE-UP ASSEMBLY AND METHOD

摘要

An improved take-up assembly used on spiral conveyor belt with interconnecting links. The improved take-up assembly includes a pivoting swing arm assembly coupled to an obstruction sensor that automatically shuts-off the drive motor used to move the conveyor belt when an obstruction is detected upstream from the take-up assembly. An optional obstruction sensor can also be used on the upper portion of the take-up assembly to detect obstructions downstream from the take-up assembly. Also disclosed is a buckling arm located above and longitudinally aligned with the belt and pivotally attached to the distal end of the lower swing arm assembly. The swing arm is also designed to pivot beyond the position where the first obstruction sensor is activated so that the amount of belt that continues to be drawn into the stack as the stack coasts to a stop.
