ABSTRACT:
An expandable modular housing is adjustably positioned with its open entrance side adjacent the output end of a conveyor feeding one or more lanes of parts. Affixed to the undersurface of the top of the housing are a pair of normally open jaws aligned with each lane. Each pair of jaws is movable along guide rails, in the direction of conveyor movement, between a first position where the jaws are opened and situated to receive a part from the conveyor, the presence of which is sensed to close the jaws and cause movement of the jaws through a second position, wherein the jaws are caused to open to release the part, to a third position, spaced from the second position, along the same direction. Below the path of movement of each pair of jaws is a position adjustable stacking table having interchangeable surfaces of different shapes onto which each part is placed in succession. The second position of the jaws is adjustable with respect to the first position to accommodate different length parts. The mechanism is adjustable to permit off-loading of parts of a large variety of different sizes, styles and materials from conveyors of different dimensions. In addition, the mechanism can be altered to accommodate different numbers of lanes of parts simultaneously.
