ABSTRACT:
A shingle stacking machine including a shingle stacking station, a shingle bundling station, and a conveyor for removing bundled shingles from the machine. The shingle stacking station includes a pair of parallel and elongated wheel assemblies rotatably mounted to a frame of the machine. A drive mechanism is provided for rotatably indexing each wheel assembly during a drive mode of operation and permits free wheeling of the wheel assemblies during a jam mode of operation. The drive mechanism includes a motor for continuously driving a vacuum operated clutch assembly. The clutch assembly includes a pair of electromagnetic valves for controlling operation of a drive shaft which is connected to the wheel assemblies through an elastomeric belt drive. The shingle bundling station is disposed beneath the shingle stacking station and includes a pair of shelf-like supports pivotally carried on the machine frame. The shelf-like supports are interconnected by an intermeshing gear arrangement driven by a linear actuator. A series of drivers are also provided to align the end and side edges of the shingles deposited at the bundling station. The conveyor apparatus is disposed beneath the bundling station for removing bundles of shingles to an area remote from the shingle stacking machine.
