Abstract
A conveying system for moving load carrying units, such as carts or pallets, along a predetermined conveying path includes an endless moving conveyor chain traveling in a chain guide channel defining the conveying path. The carts to be conveyed each have a depending movable conveyor chain engagement pin which is selectively movable between a conveyor chain engaged position coupling the cart to the conveyor chain so that the cart moves with the conveyor chain, and a conveyor chain disengaged position uncoupling the cart from the conveyor chain so that the cart remains stationary. The carts also include a fixed depending cart guide finger spaced from the conveyor chain engagement pin which cart guide finger also remains out of contact with the conveyor chain. Further, the conveyor system also includes a load carrying unit and a unit guide channel located over and in alignment with the chain guide channel along at least portions of the length of the chain guide channel. Both the fixed depending cart guide finger and the movable conveyor chain engagement pin, regardless of whether the conveyor chain engagement pin is in the chain engaged or disengaged position, are disposed within the load carrying unit guide channel as the cart moves along the portions of the conveying path including the load carrying unit guide channel to prevent the cart from skewing relative to the conveying path.
