ABSTRACT:
A load push-pull slipsheet handler is disclosed having automatic features adapting it particularly for use with driverless, automatically-guided vehicles. These features include proximity sensors which sense the distance between the slipsheet handler and a vertically-oriented external surface so as to deposit a load in a predetermined relationship to the surface either on the floor or atop another load. Load contact sensors also are provided for enabling the device to gauge the distance to a load to be picked up so as to control the approach thereto. Further sensors sense the transversely-opposite extremities of a load prior to engagement, and transversely center the push-pull assembly relative to the load. Other features include a system associated with the slipsheet clamp for sensing the presence or absence of a slipsheet tab prior to clamping, and means for permanently deforming the tab to facilitate subsequent regrasping after the load has been deposited. A vertical height sensor ensures proper elevation of the slipsheet handler for depositing a load atop another load.
