Abstract
The present invention comprises devices for receiving a plurality of elongated workpieces, devices for automatically raising the workpieces, devices for forming a single layer of a predetermined number of workpieces, devices for controlling the height and width of a stack, devices for assembling layers of workpieces into a stack of predetermined height and width, and devices for supporting and positioning the stack during formation. The self-contained machine of this invention is designed for producing a stack of elongate, stackable workpieces. The machine comprises devices for receiving the elongate, stackable workpieces and for conveying the workpieces in a generally vertical upward direction to an elevated point above the surface on which the stacking machine is supported. Vertical conveyance of the work pieces requires the use of a minimum lateral space for conducting that operation as opposed to armtype hoisting stackers in which the arm is extended and takes up a significant amount of lateral space. The devices for receiving the workpieces are at the elevated point and devices for infeeding the workpieces to a stackable layer formation device are also provided. The lateral ar…
