Abstract:
A cutting machine for cutting an elongate workpiece having first and second ends, comprising:(a) a frame;(b) a first cutting mechanism supported on the frame and defining a first rotational axis;(c) a second cutting mechanism defining a second rotational axis and supported on the frame and spaced from the first cutting mechanism;(e) a transfer conveyor supported on the frame for conveying the workpiece along a first path of travel, the first path of travel including a location that is adjacent to the first and second cutting mechanisms;(f) a feeding device supported on the frame for receiving the workpiece from the location on the transfer conveyor and moving the workpiece along a second path of travel which includes the location and the first and second cutting mechanisms so that a workpiece on the feeding device is moved along the second path of travel so that the workpiece contacts the cutting mechanisms to cut the workpiece in two locations, the second path of travel extending along a plane extending through an axis extending through the first rotational axis;(g) a plurality of transfer conveyors for moving the workpiece along the first path of travel for receipt by the feeding device, a first one of the transfer conveyors being slidably mounted to the frame so that sliding the first one of the transfer conveyors moves the first one of the transfer conveyors in a direction orthogonal to the first path of travel; and(h) an input conveyor supported on the frame for conveying the workpiece to the transfer conveyor and a switching mechanism having an air cylinder for shifting the workpiece from the input conveyor to the transfer conveyors.
