Abstract:

In a machine for strapping a skid and a supported load by the use of a strap passing through aligned openings in the skid runners, a conveyor is provided for conveying the skid through a feeding zone. A turntable including powered rollers is provided for receiving the skid and the supported load from the conveyor, for positioning same within a strapping zone, and for rotating same within. A vertical scanner comprising a vertical array of photoelectric transmitters spaced from one another, on one side of the feeding zone, and a vertical array of photoelectric receivers spaced from one another, on the other side of the feeding zone, is provided for scanning the skid being conveyed. Two horizontal scanners, each comprising a single photoelectric transmitter and a single photoelectric receiver on each side of the strapping zone, are provided for scanning the skid being conveyed after it has been scanned by the vertical arrays. Two strap guides are provided, each extending transversely and each being movable along a transverse between an extended position, in which it extends across the strapping zone, and a withdrawn position, in which it does not interfere with the skid being conveyed. The horizontal scanners and the strap guides are adjustable vertically and conjointly in response to the vertical scanners.
