Method of indexing conveyor pallets at high speeds

摘要

A pallet accelerator transfers workpiece pallets at high speeds from a pre-stop to a work stop in a conveyorized manufacturing line. While a workpiece is being processed in the work stop position, a pallet is released from a release stop into the pallet accelerator at the pre-stop position. The pallet accelerator has two fingers which engage the pallet. The pallet accelerator is pneumatically actuated to accelerate the pre-stop pallet forward while simultaneously pushing the work stop pallet downstream out of the work stop. The pallet accelerator resets for the next pallet released from the release stop while the pallet at the work stop is processed.
