Definitions

  • Each suction head may have another arcuate surface adapted to minimize the oscillatory motion imparted to the stack of already separated sheetsv 3 Claims, 9 Drawing Figures PATENTED SEP 91975 3. 904, 189 SHEET 3 [1f FIG. 6 PRIOR ART PATENTEDSEP 91975 3.904.189
  • This invention relates generally to counters for counting bills, tickets, cards, and other sheets having a definite size (referred to as sheet counters throughout this specification and the appended claims). More specifically, the invention is directed to improvements in suction heads used in such sheet counters.
  • a plurality of suction heads are ro tatably mounted on a rotary disk in an annular arrangement.
  • suction heads are rotated on their own axes and revolved around the axis of the rotary disk, sheets held in a stack by a sheet holding mechanism are successively separated into another stack by suction applied through ports formed in each suction head.
  • a suction head having an arcuate surface through which at least one port is formed to apply suction to the successive sheets held in a stack by a sheet holding mechanism.
  • the arcuate surface is such that the distance between the arcuate surface and the axis of rotation of the suction head gradually increases from one edge of the arcuate surface,
  • the suction head first contacts each foremost one of the sheets held by the sheet holding mechanism, to the opposite edge thereof, whereby the suction head is permitted to rotate both on its own axis and around the axis ofa rotary disk while imparting substantially no oscillatory motion to the sheets held by the sheet holding mechanism.
  • FIG. 1 is a schematic top plan view showing some essential parts of a sheet counter of the type to which the present invention is directed;
  • FIG. 2 is an elevational view of a suction head constituting a preferred embodiment of the invention
  • FIG. 3 is an clevational view of the suction head shown in FIG. 2 as viewed from the left;
  • FIG. 4 is a top plan view of the suction head shown in FIG. 2;
  • FIG, 5 is a schematic top plan view explanatory of the sheet counting operation by the suction head shown in FIGS. 2, 3, and 4;
  • FIG. 6 is also a schematic top plan view explanatory of the sheet counting operation by a prior art suction head
  • FIG. 7 is an elevational view of a suction head of a construction according to another preferred embodiment of the invention.
  • FIG. 8 is a top plan view of the suction head shown in FIG. 7;
  • FIG. 9 is a schematic top plan view explanatory of the sheet counting operation by the suction head shown in FIGS, 7 and 8.
  • suction heads I are rotatably mounted on a rotary disk 3 in an annular arrangement. These suction heads are rotatable clockwise about their respective axes, and the rotary disk revolves counterclockwise, as indicated by the arrows respectively in the drawing,
  • a stationary disk 4 is provided below the rotary disk 3 in coaxial relationship therewith, and a plurality of projections 5 are disposed circumferentially around the stationary disk so as to correspond to respective suction heads. These projections coact with a switch S in a known manner to count bills or other sheets 2 held in a neat stack by a sheet holding mechanism 6 comprising a support plate 7 and a bar 8.
  • a pipe 9 is provided below the stack of sheets 2 to separate the successive sheets by a blast of air supplied through its ports 10.
  • the suction heads 1 are communicated with a suction port of a vacuum pump through their respective valves in a manner such that a desired degree of vacuum is produced in each suction head only during its travel from position I to position II indicated in FIG. 1.
  • each of the suction heads I is constructed as illustrated in greater detail in FIGS. 2, 3, and 4.
  • a surface 12 of the suction head through which are formed a plurality of suction ports 11 and which is adapted for direct contact with each foremost one of the sheets 2 held by the sheet holding mechanism 6 is arched when the head is viewed cross-sectionally.
  • the distance between this arched surface and the axis of rotation of the suction head gradually increases from leading edge 12a, where the head first comes into contact with each foremost me of the sheets 2, to trailing edge 12b.
  • the rate of this gradual increase is determined in accordance with the change in the distance between the surface of the foremost sheet 2 and the circle A followed by the axis of the suction head during its revolution around the axis of the disk 3, as depicted schematically in FIG. 5.
  • the line connecting the outermost points of the suction head traveling adjacent the stack of sheets 2 and rotating on its own axis and around the axis of the disk 3 becomes substantially parallel to the surface of the foremost sheet.
  • Portion 12c of the arched surface 12 on which are formed the aforesaid suction ports 11 is rendered flat to make neat contact with the surface of each foremost sheet, and the upper edge of this flat portion 12c gradually rises to the arched surface 12.
  • a surface 13 of the suction head opposite to the arched surface 12 is of exactly the same shape as the surface 12, so that the suction head is symmetrical with respect to the line C-C passing the axis of the head and the aforesaid trailing edge 12b.
  • a surface 14 between the leading edge 12a of the first mentioned surface 12 and a corresponding edge 13a of the second mentioned surface 13 is also slightly arched.
  • surface I4 is formed to have a gently arched surface having a large radius adapted to impart minimum oscillatory motion to the sheet 2a separated from the stack of sheets 2 and transferred to a position of the countcompleted sheets.
  • each of the suction heads 1 is adapted to make three complete revolutions on its own axis during each complete revolution of the rotary disk 3.
  • the suction heads, IA When one of the suction heads, IA, is in position a, where the leading edge of the suction head abuts against the foremost one of the stack of sheets 2, the succeeding suction head IB is in position u,,.
  • This suction head 13 moves to position b when the leading suction head IA moves to position b to contact the foremost sheet at its trailing edge.
  • the succeeding suction head 18 moves to position c, to contact the next foremost sheet at its leading edge
  • the suction heads I mounted in an an nular arrangement on the rotary disk 3 as shown in FIG. 1 successively separate each foremost one of the stack of sheets 2.
  • the pipe 9 shown in FIG. I may produce currents of air under pressure through its ports 10 to prevent two or more sheets from being separated simultaneously. This objective can be accomplished more easily if, as shown in FIGS. 2 and 3, an overhanging step is formed under the portion of the arched surface 12.
  • the sheets successively separated by the suction heads as above stated are counted as the projections 5 strike against the switch S in accordance with the prior art.
  • FIG. 6 schematically illustrates the track followed by each suction head I, of the prior art as it revolves clockwise on its own axis and counterclockwise around the axis of the rotary disk 3, as indicated by the arrows in the drawing.
  • FIGS. 7 and 8 illustrate another preferred embodiment of the invention, which also is calculated principally to minimize the oscillatory motion imparted to the stack of already separated sheets 2a.
  • the suction head shown in FIGS. 7 and 8 also includes arched surfaces 12, 13 and 14, the arched surface 12 including a concave portion 121' through which are formed an array of suction ports II.
  • each of said suction heads being rotated on its own axis while revolving about the axis of said rotary disk and having at least one suction port adapted to successively suck up a sheet from said sheet stack; the improvement wherein each of said suction heads is generally triangularly shaped and includes as one of its sides an arched sheet suction surface'through which said suction port is formed, said arched sheet suction surface acting to provide direct contact with each foremost one of the sheets held by the sheet holding mechanism, and further includes as another of its sides a convexly arched sheet contact surface provided with a gently arched surface having a large radius and adjacent to said sheet suction surface, said convexly arched sheet contact surface being adapted to cause transfer of the portion of said sheet contact surface positioned
  • said sheet suction surface includes a recessed portion, said at least one suction port being formed through said recessed portion.
