Abstract

Wheeled carts are pushed onto an inlet end of a conveyor and are automatically advanced, one at a time, to a cross conveyor for delivery to a cart loader conveyor. A cart loader is provided near the outlet end of the cart loader conveyor for automatically loading bundles into a wheeled cart. The input conveyor advances wheeled carts one cart position at a time. Cart positions along the input conveyor are monitored by sensors to automatically control advancement of wheeled carts therealong. A cart delivered from the outlet end of the input conveyor to the cross conveyor activates a cross conveyor limit switch advancing the cart delivered thereto to a position for feeding a wheeled cart onto the cart loader conveyor. A limit switch is actuated when the wheeled cart reaches this position where upon a push bar pushes the cart activating the limit switch onto the cart loader conveyor. The conveyor system in cart handling are preferably operated by hydraulic devices due to their compactness.
