Harrington, Vestal, N.Y., assignor to International Business Machines Corporation, New York, N.Y., a corporation of New York Filed Feb. 26, 1962, Ser. No. 175,468 13 Claims. (Cl. 271-76)
  • This invention relates to sheet handling apparatus, and more particularly to apparatus which is capable of driving and reorienting sheets of random varying sizes and thicknesses.
  • One object of this invention is therefore to provide an improved sheet handling apparatus which is more compact and less expensive than those heretofore proposed.
  • Another object is to provide an improved sheet han dling apparatus in which sheets initially move in one direction and are twice diverted so they will be dropped into a selected stacker pocket while moving in the opposite direction and with a different edge foremost than had L been foremost during movement in said one direction.
  • a further object is to provide an improved sheet handling apparatus wherein, as sheets are advancing along a predetermined path with one part foremost, they will be diverted obliquely from said path and, without stoppage or interruption, be reoriented so that a different part of the sheet is foremost.
  • Still another object is to provide an improved sheet handling apparatus which provides continuous control of the movement of sheets despite substantial random variations in their sizes and thicknesses.
  • the improved sheet handling apparatus comprises means for advancing sheets one edge foremost along one path, and means for driving sheets at an oblique angle from said path into another path and concurrently reorienting the sheets so that another edge is foremost.
  • the driving means comprises endless means providing bites at points spaced transversely across said one path so as to be substantially simultaneously engaged by said one edge While a sheet is still moving in the direction of said one path.
  • the driving means conveys the sheets in a U-shaped course thus turning each sheet upside down and at the same time turning it through an angle substantially double said oblique angle.
  • Stacker pockets are disposed along a third path which diverges at an obtuse angle from the exit end of said other path.
  • the speeds at which the sheets move along said other path and third path are so related to the exit speed of the sheets from said one path as to prevent overlapping of sheets at any point. For example, if sheets are diverted at an oblique angle of 45 from said one path while traveling at a certain speed, they will be driven at 1.414 times said certain speed while in said other path; and if said third path diverges at an angle of. from said other path, the sheets will be driven along said third path at a speed .707 times the speed the sheets had upon leaving said other path. As a result, the speeds of the sheets while moving in said one path and third path will be substantially identical.
  • FIG. 1 is a plan view of a portion of a sheet hand-ling apparatus embodying the invention
  • FIG. 2 is a fragmentary elevational view, to enlarged scale, taken in the direction of arrow 2 in PEG. 1;
  • FIG. 3 is a fragmentary elevational view, to enlarged scale, taken in the direction of arrow 3 in FIG. 1;
  • FIG. 4 is a fragmentary section, to enlarged scale, taken along the line 4-4 of FIG. 1;
  • FIG. 5 is a simplified perspective view, to reduced scale, of the apparatus embodying the invention.
  • sheets suchas bank checks 10 are advanced from a hopper (not shown) over a stationary bed plate 11 by a plurality of suitably driven radial-1y slotted discs 12.
  • These discs are of the type disclosed and claimed in the co-pending application of D. W. Brearley, U.S. Serial No. 172,463, filed February 12, 1962, and assigned to the assignee of the present invention.
  • these discs 12 are spaced along, and at a slight oblique angle to, a registration edge 13 that is provided by the upturned rear edge of bed plate 11.
  • the discs 12 drive each successive check at said oblique angle until it strikes edge 13.
  • each successive sector of a particular slotted disc 1-2 is rotated into contact with a check, such sector will yield laterally and thereby limit the aligning component of force on the check substantially to that necessary to efiect lateral deflection of a single sector.
  • the discs 12 serve to drive the sheets forward and at the same time align them laterally against the registration edge.
  • each sheet After each sheet is laterally aligned against edge 13, and while it is moving forward at a preselected speed, it will pass a work station which, in the embodiment illustrated, is a read station R.
  • a read station R At this station, means (not shown) is provided to read from each check 10 magnetic ink indicia that is contained in a line or lines parallel to the long edge of the check and hence parallel to the registration edge 13.
  • each check passes station R, it will enter between a suitably driven roll 14 and a suitably driven belt 15; and thereafter said edge will pass under a plate 16 that is downpath of said roll and overlies the belt.
  • the plate 16 has a plurality of holes arranged in two longitudinally extendng rows. Extending upwardly through each such hole is an annular member 17 having a flange 18 that rests against the under side of the plate. The space between flange 18 and belt 15 always exceeds the thickness of any check.
  • a plastic retainer ring 20 preferably is inserted in the lower or flanged end of each member 17 to prevent the associated ball 19 from dropping through the annular opening when plate 16 is raised or removed.
  • One retain- 3 ing bar 21 preferably extends through all members of each particular row at a point above the respective balls 19 to prevent them from being ejected upward out of the members.
  • each check lltl exits from under plate to, its leading edge simultaneously enters the transversely spaced bites of two sets of endless members.
  • one set of these endless members consists of two rolls 22, 23; and the other set consists of a roll and a large roll or drum 25.

  • Each pulley 3? drives a fiat belt 38 having a run which impinges upon a substantial portion of the periphery of drum and diverges from the drum into a path that extends beneath belt 15 and at an angle equal to the angle 0 toward a series of side-by-side arranged stacker pockets 39.
  • Each belt 38 passes around idler pulleys dll and a tensioning pulley 41.
  • Each pulley it? is adjacent the first stacker pocket 39, and each pulley all is interposed between the associated driven pulley 3'7 and pulley 40.
  • the roll or drum 25 is rotatably mounted on a stud 42 and is rotated by the belts 38; however, if preferred, a driven shaft may be substituted for the stud 42 for driving the drum and thereby driving the belts.
  • a plate 43 is spaced somewhat above those portions of the flat belts 38 that extend from drum 25 to the respective pulleys 40.
  • Plate 4-3 has two rows of holes, each row being disposed above a respective one of the belt 33.
  • a member 17 is inset into each hole to retain a corresponding steel ball 19.
  • each of these sets comprises a belt 44 and a spring-biased idler roll 45 that are disposed directly above the nearest side Wall 46 of the first stacker pocket.
  • the belts 44 are transversely spaced and flat; and they move in planes that are parallel to each other and to the registration edge 13. Assuming that the check is not to be stacked in the first pocket 39, it will be advanced by the belts 44 successively past rolls 45 and then past rolls 4-7, 48, 49 and 50 (FIG. 3).
  • the rolls 47, d8 are driven by the belts 44 to frictionally drive an intervening speed-reducing pulley 51.
  • Pivotally supported on the supporting stud for pulley 51 is an arm 52 that carries a grooved wheel 53; and a belt 54. is driven by said pulley and runs around said wheel to urge the leading edges of all checks into flush contact with the leading side wall as of the pocket 39.
  • the checks are supported on a platform 55 which preferably it tilted, as shown in FIG. 3, and is resiliently biased upward by a spring 56.
  • the belts 44 are driven from a common driven shaft 57 through respective pulleys 5t and around respective tensioning pulleys 41a.
  • the rolls 49 preferably are rotatably carried on a common fixed stud; and the rolls Stl are spring-biased toward the respective rolls 45-9 to keep the belts 44 in effective contact with rolls 4-? to assure proper driving of the checks.
  • rolls 49, 5t willbe disposed'at the entry side of the pocket (as shown in FIG. 3) in place of the pulleys 55S and rolls l5; and within each pocket there are provided the elements 47, 48 and 51 to 56 just described.
  • a plurality of stacker magnets 60 is provided, one for each pocket 39, although only one is shown in FIG. 1. These magnets are selectively energized according to the information read at read station R to select the particular pocket 39 into which a check is to be diverted. More specifically, upon energization of a particular magnet 60, a deflector member 61 will be caused to rock clockwise about a fixed pin 62 to an upper limit position in which it is shown in FIG. 3 and which is defined by contact with a stop surface 63. When the deflector member till is in its upper or deflecting position, a check will be diverted from contact with the belts 44 and will be advanced along the inclined lower side of deflector member el and toward the stack in that particular pocket.
  • the belt will drive the check forward relative to vthe platform 55 and stack until the leading edge of the check is flush against the side wall l! of that particular pocket.
  • the platform 55 will drop a corresponding degree by compressing spring 56; and in this way, the height of the stack will be maintained reasonably uniform.

  • the angle 0 is 45 and the check is driven 180 around the drum 25.
  • the check will be turned over; and its long edge (rather than the short edge) will now be foremost.
  • the check will traverse its former path parallel to edge 13 and then head along a straight course in a direction defined by the complement of the angle 0. That is, the check will now be moving horizontally but angularly toward the side-by-side arranged stacker pockets 39 at the front of the apparatus.
  • peripheral speed of the various endless members are so controlled and related as to prevent undesirable overlapping or shingling of the checks.
  • the check is moving at a velocity V parallel to the registration edge 13 at the time it enters between the'bites of rolls 22, 23 and 24, 25.
  • each belt 38 should be driven at a lineal speed V that is at least equal to V divided by the cosine of the angle 0; and each belt 44 should be driven at a lineal speed V that is at least equal to the product of speed V and the cosine of angle 0.
  • V would be at least 1.414 times V and V would be at least .707 times V If V were exactly equal to 1.414 times V and V were exactly equal to .707 times V then V would, of course, be equal to V
  • a sheet such as a check, initially moves longitudinally right to left, as shown in FIG. 1, until it reaches the turning or reorienting station at drum 25. Then, after leaving the drum, it moves angularly forward at a different elevational level for a short distance until it reaches the belts 44. Then, it moves longitudinally left to right.
