Abstract
Vehicles supporting a load are propelled between a load receiving station and a pallet unloading station. When the loaded vehicle is in a predetermined location, the pallet unloader is actuated causing the unloader ram element of the pallet unloader to contact the load and urge the load off the support vehicle and onto the load receiving station. This unloading is accomplished while the vehicle continues to move through the unloading station. The rate of unloading is coordinated with the speed of the vehicle through the unloading station.
Claims5
Apparatus for transferring a palletized load from a moving load supporting vehicle as said load supporting vehicle moves through an unloading station, said palletized load moving with said load supporting vehicle comprising:
- a load receiving station for receiving said palletized load from said moving load supported vehicle;
- an unloader ram having a leading edge for contacting said palletized load, said unloader ram mounted for extension along a predetermined path;
- drive means for driving said unloader ram along said predetermined path;
- actuator means responsive to the position of said load supporting vehicle relative to said unloading station for actuation of said drive means urging said unloader ram to discharge said palletized load from said moving load supporting vehicle while said palletized load continues to move with said moving load supporting vehicle to said load receiving station without relative motion between said palletized load and said leading edge of said unloader ram.
