Conveyor track switch

摘要

Track switch for diverting load carriers from a main trackway into a branch trackway in a "power-and-free" or "free" type conveyor system. Switch comprises a frog connected between the main and branch trackways, and a load-carrier diverter pivotally mounted externally of the frog. Diverter has vertical plates on each side of the frog with inwardly-directed bottom margins having opposed guide edges for action on carrier guide elements projecting through a slot in the base of the frog. A pneumatic cylinder and ram device pivots the diverter between straight-through position and a divert position.
