Definitions

  • PNEUMATIC TRANSPORT DEVICE Filed July 25, 1966 2 Sheets-Sheet 2 INVENTOR JONG-DOK KIM av I ATTORNEYS United States Patent 3,403,904 PNEUMATIC TRANSPORT DEVICE Jong-Dok Kim, Kunststoff, Germany, assignor to Siemens Aktiengesellschaft, Kunststoff, Germany, a corporation of Germany Filed July 25, 1966, Ser. No. 567,621 Claims priority, applicatigo; Gsrmany, July 27, 1965,
  • the present invention relates to a pneumatic transport device for sheet-like record carriers and the like.
  • the problem exists of withdrawing or segregating individual record carriers which are fed into a magazine in the form of stacks or piles, and to subsequently feed them to a transport device.
  • a known arrangement solves this problem by a rotating suction drum which, on its circumference, has a number of openings. Vacuum is applied to the drum whereby the record carriers are retained against the drum by the external air pressure carried along in the direction of rotation by the resulting frictional force.
  • roller to which the respective record carriers to be transported are drawn by suction
  • the roller is provided on its circumference with at least one annular groove, which can be selectively connected with a suction device, with the roller being so disposed in a stationary casing or housing, closely surrounding the roller, that the latter is rotatable.
  • the casing is provided with an opening on its side facing the record carrier, of such size and proportions that the roller is presented, for direct contact with the record carrier, over the exposed area.
  • FIG. 1 is a perspective view of a roller drum embodying the invention.
  • FIG. 2 is a side elevational view, with portions in section, of a transport device embodying the drum structure illustrated in FIG. 1.
  • the transport device illustrated comprises a roller W which is enclosed in a casing or housing G.
  • the inner diameter of the casing G is sufficiently greater than the outer diameter of the roller W that the roller may freely rotate within the housing.
  • the roller body is provided with two grooves N1 and N2 which are operatively connected with a suction device by means of tubular connections S1 and S2, respectively.
  • the case 3,403,904 Patented Oct. 1, 1968 is provided with an opening which is so proportioned that the surface of a record carrier to be transported may be brought into engagement with the outer plane of the roller W.
  • the transport device preferably, is so arranged with respect to a stack of record carriers that when vacuum is applied, the front end, in transport direction, of the record carrier is drawn close to the roller.
  • the roller is driven by suitable means, which for reasons of simplicity and clearness, is not illustrated in FIG. 1, and transports the record carrier forward by approximately one sheet-length, whereupon it is picked up by a transport device of customary construction, for example, by a pair of cooperable feed rollers.
  • the roller is provided, in the central portion, with another groove N3 in which is disposed a flat suction finger F extending tangentially.
  • the forward end of the suction finger is curved with the radius and center of curvature of its outer surface facing the record carrier coinciding with that of the suction roller. That part of the suction finger F disposed within the groove has, in its lower face, a number of openings L through which air is drawn prior to the beginning of the transport process.
  • the casing or housing that it is closed at the respective ends of the roller, or to vary the section facing the record carrier without respect to the width of the record carrier.
  • tubular suction connections S1 and S2 one or several channels, arranged on the inner face of the casing G and accessible from the exterior, may be employed.
  • FIG. 2 illustrates the application of-the invention to a machine, for example, a sorting machine wherein the record carrier may be deposited in either of several filling trays.
  • the record carriers are initially disposed in a stack within a container suitably constructed to maintain the top sheet of the stack at a predetermined elevation, from which it is withdrawn by roller means.
  • Numerous nozzles or orifices for the withdrawal or discharge of air are utilized, the direction of air flow being indicated by arrows associated therewith.
  • the leading edge portion of the top sheet of the stack is drawn upwardly by an air-withdrawal nozzle positioned thereabove into engagement with the roller drum, which is constructed in accordance with the disclosure of FIG.
  • a similar nozzle being disposed at the opposite side of the roller to raise the edge of the record carrier for engagement between two feed rollers.
  • Three air-withdrawal nozzles are disposed at the discharge side of the rollers, two being disposed above the transport path and one therebelow. The latter nozzle is operative to draw the leading edge portion of the record carrier downwardly, whereby the carrier may be deposited in the first tray, while the other two nozzles are operative to maintain the leading edge portion of the carrier in elevated position for transport to the next tray.
  • Both trays may be provided with a suitable brake plate and air-withdrawal orifice.
  • a similar angleshaped lever Associated with the second tray is a similar angleshaped lever, additional feed rollers, and respective air nozzles or orifices for controlling the movement of the record carrier in accordance with the desired operation.
  • a record carrier can be deposited in either tray, the carrier being efiectively braked in a suitable manner.
  • a pneumatically operated transport device for moving sheet-like record carriers having a roller, a housing substantially enclosing the roller, a cordal section of said roller projecting from said housing, and pneumatic rneans associated with the roller to retain the record carriers on a portion of the roller when the roller is rotating, the improvement of: a circumferential groove around said roller and means extending into a portion of the said groove in the said cordal section effective to attract the said record carriers to the said roller and conform portions of the said record carriers to the surface of the said roller.
  • a transport roller for moving sheets of material comprising: a cylindrical roller, a housing substantially enclosing said roller, a cordal section of said roller projecting from said housing, pneumatic means associated with said roller for retaining said sheets on a portion of said cordal section, a circumferential groove in said roller intermediate the ends thereof, a stationary finger extending into said groove adjacent said cordal section, and said stationary finger pneumatically actuatable to attract said sheets thereto.
