Bottom saw blade height adjustment

摘要

The invention provides a device for use in the extraction of bottles or the like from cartons travelling in a stream on a conveyor, each carton having a bottom wall and associated side walls. The device has a saw blade adapted to extend across the conveyor to cut the associated side walls just above the base which is thereby severed. The saw blade is vertically adjustable so as to accommodate cartons having bases of different thickness' and thereby ensure avoidance of damage to the bottles sitting on said bottom wall. A sensor positioned upstream of said blade determines the vertical position required for each passing carton and transmits a signal which results in the blade being positioned as required.
