Title: Improvements in and relating to means for feeding pieces of magnetizable sheet metal to machine tools
IPC: B65G47/92
Filed: 1920-06-23
Abstract: 146,270. Werner, F. Feb. 26, 1916, [Convention date]. No Patent granted (Sealing fee not paid). Pile tables and supports for sheet feeds; separators; carriers. -A device for feeding magnetiza.ble pieces of sheet-metal to a machine includes electro-magnetic means for ensuring the feed of only one piece at a time. The pieces are piled up in a receptacle A and are fed to the machine by a device C mounted on a lever g having a lost-motion connexion through a pin i and slot k with a twoarmed lever f, f<1>. Both levers rotate on a fixed shaft e. the arm f<1> of the two-armed lever being connected to a mechanical drive J. The lever f carries a pivoted wedgeshaped member h of insulating-material, on one side of which are contacts s, t adapted to bridge sucessively pairs of contact rails 1, 2 and 3, 4 when the lever is moved from the receptacle A towards the machine. In the return movement to the receptacle, the insulating face of the member h rides over the contact rails and no circuits are completed. The receptacle A comprises a tube a and a screw-spindle c which, at each operation of the feeding-device, is raised a distance equal to the thickness of one of the work pieces by a trip gear b operated from the machine tool. A small roller n carried by the lever g engages a projection o<1> in order to lift the device C over the edge of the receptacle A. Owing to the lost motion connexion between the levers f, g, the device C remains over the receptacle A for a short time after the lever f commences its return movement; during this period the contact s engages the contact-rails 1, 2 and completes the circuit of an electro-magnet x whose armature y forms the end boards of a bellows z. The attraction of the armature causes a partial vacuum in the chamber 14, and at the same time an air cushion w in the mouth of the device C is inflated through a tube 6 connected to the bellows. The top workpiece is thereby attracted and, when the lost motion has been taken up, is lifted off the receptacle. The contact t then engages the rails 3, 4 and completes the circuit of an electro-magnet F, through the core 7 of which extends a brass rod 8 terminating in a brass disk 9 which is pressed on to the work piece by an adjustable spring 10. Immediately afterwards the contact s leaves the contact rails 1, 2 and the electro-magnet x is deenergized. The suction then ceases and the air cushion w is deflated. If more than one workpiece has been attracted, the magnetic attraction between the work-pieces and the core 7 is sufficiently great to overcome the spring 10, and the work-pieces are drawn towards the core. The rod 8 thereupon closes contacts 11, 12, and short circuits the electro-magnet F and the work-pieces drop off the brass disk 9 before reaching the machine.
