Definitions

  • Another object of the invention is to provide a novel interrelated arrangement and control for a group of fluid actuating motors of a stock feeder whereby producing an operative indexing stroke and then a stock advancing stroke of the feeder in sequence is accomplished by supplying fluid pressure to all of said fluid motors simultaneously and then exhausting fluid pressure from all of said fluid motors simultaneously.
  • FIGURE 1 is a plan view of the instant stock feeder.
  • FIGURE 3 is a right hand end elevational view in partial section with some elements omitted and illustrates the construction of the movable feed head.
  • a sealing means such as annular ring gasket 155 is secured to the said shoulder 154 so that when the cooperating face portion 153 of the main piston 152 engages said gasket at the end of each stock feeding stroke any fluid pressure leakage past the piston 152 is cut off from and cannot reach the forward or left end of the cylinder 60 and thus escape through bore 64 which is of course then connected to the valve exhaust port 114.
  • the effective inside diameter of ring gasket 155 is made greater than the effective outside diameter of the piston rod 150 so that the effective area on the leftside of the main piston is still greater than that on the right side thereof when the :parts are in their said normal positions.
  • the sealing gasket 155 may be carried by the piston 152.
  • a first continuously acting biasing means normally operative to move said feed head in said stock feeding direction
  • a first fluid motor means operable to move said feed head in said indexing direction against the action of said first biasing means
  • a stock gripping means mounted on said feed head and movable to stock gripping and releasing positions;
  • a first fluid conduit means for conducting fluid pressure to the stock feeding side of said first double acting fluid motor and to the stock gripping side of said double acting fluid motor on said feed head so as to thereby grip said stock and advance an incremental length thereof;
  • a feed head reciprocally mounted on said frame for movement in forward and rearward directions;
  • control valve means for controlling the simultaneous supply of fluid pressure to said first fluid motor for actuating said feed head and to the other end of said second fluid conducting means for operating said double acting fluid motor against the continuous fluid action at said one side of said double acting fluid motor on said feed head for operating said stock gripping means.
  • valve control means for controlling the flow of fluid pressure to said first fluid conduit means
  • valve control means comprising means defining a valve bore in said main body
  • closure member for closing an end of said bore, said closure member having a valve stem bore formed therethrough which communicates with said valve bore;
  • valve stem means movably disposed in said valve stem bore
  • valve head disposed in said valve bore and coupled to the inner end of said valve stem means
  • a second fluid conduit means formed in said closure member and communicating at one end thereof with the radial inner side of said sealingly engaged face portions and at the other end thereof with said first fluid conduit means;
  • a device for feeding stock comprising a frame
  • a first double acting fluid motor in said body member for reciprocating said feed head
  • At least one double acting fluid motor mounted on said feed head for operating said stock gripping means
  • a third fluid motor on said frame for operating said retainer means so as to grip said stock
  • stock clamping means mounted on said frame for movement between stock clamping and release positions
  • a main fluid motor for actuating said feed head
  • At least one additional fluid motor mounted on said feed head for operating said stock gripping means
  • valve control means for controlling the operation of said feed head and stock gripping means
  • said additional fluid motor on said feed head comprising a double acting fluid motor
  • a stock feeding apparatus operable through alternate feed and indexing strokes for intermittently advancing stock material into a work station: comprising a main frame including a main body member; H
