ABSTRACT:
A bar end dropper for forging machines or the like is disclosed which automatically operates to reject blanks cut from the end of the piece of stock which are of unsatisfactory length and to adjust the feed when necessary to ensure that the ends of pieces of stock being fed into the machine are a sufficient distance from the shear plane of the cutter to ensure a clean cutting operation. As sequential pieces of stock are fed to the machine, they are positioned in the measuring position and the measuring carriage moves in to position a sensor a distance from the shear plane determined by the length of the stock. This automatically positions the sensor. The sensor operates to sense the passage of the rearward end of the stock and determines (1) if the portion of the stock extending past the shear plane is of insufficient length to produce a usable blank and operates controls to cause automatic rejection of such piece or (2) that the ends of the pieces of stock will be an insufficient distance from the shear plane to produce a clean cut. In the latter event, the sensing assembly initiates a short feed operation to locate the interface between the two ends of stock a sufficient distance from the shear plane to ensure a proper cut.
