The company's automatic bar loader is designed to automatically load and feed round bars to multi-spindle screw machines. The principal advantage of the stock reel is that it only needs replenishing occasionally to provide the screw machine with a continuous supply of stock, eliminating the downtime caused by manual loading. The loader consists of a bar magazine that is a stock reel and a bar loader. The complete assembly is positioned behind and in line with the multi-spindle screw machine. The magazine contains a sufficient supply of bars to ensure a continuous production. The reel is made up of longitudinally split reel tubes, the number of which equals the number of spindles in the automatic. As a bar is fed into the machine by a roller feed system, it passes a depletion switch sending an empty reel tube, the tube will be open through a pneumatic/mechanical system, and a bar will be metered into the tube by an escapement mechanism. The tube will then close preparatory to feeding, when indexed in the feeding station. This loading sequence takes place during the machine working cycle. As the bar is indexed into the feeding station it is fed forward into the screw machine by the feed rolls that are closed on the the bar pneumatically. The roll feed system is an integral part of the bar loader. The signal to the roll closing pneumatics is provided by a cam operated switch.
