Definitions

  • a conveying device for conveying sheets of cardboard, paper, or synthetic plastic foil upon a table of a sheet processing machine and into abutment with front and/or side stops on the table effects correct location of the sheets with respect to the stops by airflows directed upon the sheets from below.
  • These airflows constitute moving air cushions supporting and conveying the sheets toward the stops and retaining the sheets in abutment therewith.
  • the invention relates to a conveying device for sheets made of cardboard, paper, synthetic plastic foils, etc., for moving said sheets either following each other or in overlapped or shingled arrangement, and more particularly, to a conveying device for moving the sheets into abutment with stops on a table of a sheet-processing machine.
  • the invention also provides that the direction of the airflow with respect to the locations of the stops is adjustable by means of varying the angular positions of the nozzles from which the airflows emanate, either singly or jointly.
  • FIG. 1 is an elevational diagrammatic sectional view of a sheet-conveying device according to the invention
  • FIG. 2 is a plan view ofFlG. 1;
  • FIG. 3 is a diagrammatic elevational view, partly in section showing movements of sheets from a stack of sheets to the conveying device.
  • FIG. 4 is an edge view seen in the direction of an arrow in FIG. 1.
  • FIG. 3 shows a sheet stack table assembly 20, which should be visualized as being equipped with conventional means for lifting and lowering the stack, and also with a suction head for supplying sheets l8, 19 to a sheet table 1 in a conventional fashion.
  • This sheet table coacts with the sheet-conveying device according to the invention which comprises a table 2 on which front stops 3 and side stops 4 are mounted, either rigidly or movably.
  • Side stops 4 are preferably provided with a guide such as a guide 5 made of sheet metal to assure that sheets such as sheet 19 are guided toward the front stops.
  • Table 2 has fitted therein two or more nozzle assemblies, four nozzle assemblies 6, 7, 8 and 9 being shown by way of example.
  • the airflows emanating from the nozzle assemblies are directed toward front stops 3 and if desired also toward side stops 4.
  • the nozzle assemblies should be visualized as being of conventional design and connected to suitable pressure air conduits (not shown). They are preferably rotatably mounted within the table so that the angular positions of the nozzle assemblies can be adjusted. Adjustment can be effected for each nozzle assembly individually, or all or some of the nozzle assemblies can be ganged for joint adjustment.
  • Suitable adjustment means can be readily visualized.
  • a common shaft 12 which, via a gear 10 and a worm I1 is coupled to each of the four nozzle assemblies.
  • a hand wheel 13 serves to turn the shaft and thus I the nozzle assemblies as desired. The hand wheel is advantageously so placed that the nozzle assemblies can be adjusted when and while they are in operation.
  • the exits of the noule assemblies are preferably so ar ranged that air emanates from each nozzle assembly in the manner of an air sheet, as it is indicated at l4, l5, l6 and 17.
  • the nozzle assemblies may be disposed in one or more rows and such rows may be parallel to each other.
  • Sheets are conveyed either one after the other or in overlapping or shingled arrangement by suitable and conventional conveying means toward front stops 3.
  • a sheet such as sheet 18 comes within the range of airflows l4, 15, I6 and 17, it is carried by these airflows in the manner of moving air cushions toward the front stops 3 and also toward abutment with side stops 4.
  • the continuing moving action of the airflows maintains the sheets in abutment with the stops until the sheets are gripped by gripping means of the printing press.
  • a table having stationarily mounted thereon front stops and side stops for respectively lengthwise and sidewise locating sheets fed upon the top surface of the table and conveyed thereon toward the stops;
  • nozzle means rotatably mounted in said table substantially flush with the top surface thereof and disposed anteriorly of said stops as seen in the direction of conveyance of the sheets, said nozzle means being oriented to direct airflows substantially parallel to the plane of the table surface and toward the front stops and the side stops for floatingly conveying sheets along the table surface into engagement with said front stops and side stops and retaining the sheets in said engagement;
  • nozzle means comprise a plurality of spaced-apart nozzles disposed crosswise of the width of the table surface.
