When it comes to the automatic loading and unloading of billets, shafts, casting parts and bars at a floor area requirement of only 2.25m x 2.25m there's nothing to beat "Winning Sam" which was developed by Samsys in Germany.
This innovative universal loader concept allows the automatic loading / unloading of slugs, shafts and form parts. "Winning Sam" multi-task loader also provides the option to reverse the parts over in order to machine the other side on single-spindle lathes.
"Winning Sam" also allows you to feed round or profiled bar stock with the same multi-task loader, with the additional option of recovering the machined parts, separating chips and stocking fragile parts in a part magazine. The "Winning Sam" multi-task loader recovers end of bar scrap, and separates it from chips and machined parts. It is still, however, possible to pass parts on to a part control station interfaced with the lathe in automatic mode.
The concept is based on a 3-axis gantry to which a bar loader and one or several part / bar storage magazines have been integrated. The gantry deals with feeding the slugs and unloading and storing of machined parts. The bar loader is mounted on horizontal and vertical axes, which allow easy pick-up and positioning of bar stock.
The third axis manages the insertion of the bars into the spindle and material feeding. The gantry recovers the parts and end of bar scrap. With the gantry's rapid feed, up to 90 m/min and 60 m/min for the bar loader, "Winning Sam" allows quick loading / unloading of parts and bar stock. A large touch-screen and teach-in mode for initial and final positions make programming easy and facilitate fast start-up and change over, thus making the "Winning Sam" suitable for small and medium-sized production batches.
