Description

Title of the Invention APPARATUS FOR FEEDING AND ACCELERATING SHEETS
Field of the Invention The invention is in the field of sheet handling apparatus and, more particularly, the field of high speed currency counters.
Background of the Invention There are known in the prior art various forms of sheet handling devices which are adapted, for example, to count sheets of currency or the like at a high rate of speed. One such device is shown in DiBlasio patent 4,474,365 issued October 2, 1984. In the arrangement shown in this patent, sheets of currency or the like are removed from the bottom of the stack and fed one by one by means of feed rollers and cooperating stripper shoes along a curved path formed by a curved guide mounted adjacent to the feed rollers. An idling accelerating roller which is coaxial with the feed rollers and a driven accelerator roller form a nip adjacent to the lower end of the curved guide for receiving advancing sheets and feeding them to a stacker or the like.
In operation of the apparatus described above, under the action of the feed rollers and strippers sheets being advanced are pushed against the curved guide as they advance toward the accelerating roller nip. When the sheets are picked up by the accelerating rollers, they are snapped against the feed rollers, producing a popping noise which at high speeds of operation is both annoying and distracting.
In the arrangement shown in the DiBlasio patent, the

improved currency counter having a predetermined presettable stripper shoe adjustment.
A still further object of my invention is to provide an improved currency counter having a stripper adjustment which can be operated without removing the cover of the machine.
Other and further objects of my invention will appear from the following description.

Description of the Preferred Embodiment
Referring now to FIGURES 1 and 2, my improved currency counter indicated generally by the reference character 10, includes a cabinet 12 provided with a cover 14 which may be opened or removed in any manner known in the art. The apparatus includes an input tray 16 on which a stack of currency notes or the like to be counted are placed. A pair of pickers 18, one of which is shown in the drawings, are carried by a shaft 20 which is driven in a manner to be described to cause the pickers 18 to remove the lowermost sheet in the stack.
Sheets removed from the stack by the pickers 18 are received by feed rolls 22 and 24 carried by a shaft 26 which is driven in a manner to be described to advance the sheets along a curved guide 28 having respective pivot supports 30 and 32 by means of which the guide is pivotally supported in the cabinet 12.
Sheets being advanced along the curved guide by the feed roll 22 and 24 are received by the nip between an accelerator idler roller 34 supported on a bushing 36 on shaft 26 and a driven accelerator roll 38 carried by a shaft 40.

Shaft 40 is driven in a manner to be described hereinbelow to cause the sheets to be advanced along a stationary guide 42 to stacker wheels 44, one of which is shown carried by a shaft 46. Referring now to FIGURES 3 and 4, one form of drive system which may be used with my improved currency counter includes a motor 48 driving a shaft 50 carrying a double pulley 52 connected by belts 54 and 56 to a double pulley 58 on the shaft 40 carrying the driven accelerator wheel 38. A smaller gear 60 carried by shaft 40 meshes with a relatively larger gear 62 on the feed wheel shaft 26 to drive the feed wheels 22 and 24.
A pulley 64 on shaft 26 drives a pulley 66 on picker shaft 20 by means of a flat belt 68 to rotate pickers 18. A pulley 70 on shaft 40 drives a belt 71 to drive a pulley 72 on an idler shaft 74. A smaller diameter pulley 76 on shaft 74 drives a pulley 80 on stacker shaft 46 by means of a belt 78.
It is to be noted that the parts of the drive system just described are so constructed and arranged in a manner known to the art as to drive the various parts of the system at the proper speeds to achieve the desired result of moving the sheets from the input tray 16 through the apparatus so as to be deposited by the stacker wheels 44 on a suitable output tray (not shown) .
Referring now to FIGURES 1, 6 and 7, my apparatus includes respective stripper supports indicated generally by the reference characters 82 and 84 molded from a suitable

synthetic resin. Each of the stripper supports 82 and 84 is formed with an integral resilient arm 86 having a shoe carrier 88 provided with suitable slots or the like for supporting a stripper shoe 90 so that the respective shoes 90 cooperate with the feed wheels 22 and 24 to assure that only one sheet at a time is advanced by the feed wheel 22.
As has been explained hereinabove, in operation of feeders of the prior art, the feed wheels move the sheets in such a way that the” sheets tend to follow the guide 28 as they move toward the nip between the accelerating wheels 34 and 38. When they are picked up by the accelerating wheels the sheets are snapped against the feed wheels 22 and 24 with a popping action which is both distracting and annoying, particularly at the speed at which devices of this nature operate. Referring now to FIGURES 2 and 5, I provide my apparatus with means for inhibiting the popping action just described which occurs as sheets are snapped against the feed wheels in the prior art. More specifically, I provide the guide 28 with a rib 92 located between the two feed rollers 22 and 24 and extending along the feed path over the portion of the guide 28 from the point at which it leaves the nip between the feed wheels 22 and 24 and the strippers 90 and the point at which it is picked up by the accelerating rolls 34 and 38. In order to facilitate the passage of sheets between the idler accelerator roller 34 and the guide 28 while accomplishing the object just described, I provide the idler accelerator roller with a peripheral groove 94 for accommodating the rib 92.

-6- Referring again to FIGURES 1, 6 and 7, each of the stripper supports 82 and 84 is secured to the back of the guide 28 by means of a pair of threaded studs 96 and 98 which are threaded through suitable bores in the supports and into threaded holes in the guide 28. It will of course be appreciated that the ends of the studs do not extend beyond the inner surfaces of the guideplate 28.
The position of the resilient arm 86 of a support, such as support 84, can be adjusted relative to the rest of the support by means of a set screw 100 which extends through a bore in the support and into engagement with the arm 86.
The supports 82 and 84 have respective heads 102 and 104 which are connected by a bar 106. A rod 108 extending across the housing 12 between sides thereof is formed with a flat 110 to which one end of a latch spring 112 is secured by a screw 114. The other end of the latch spring 112 is hooked over the bar 106 so that the spring normally urges the assembly of the guideplate 28 and supports 82 and 84 to rotate in a clockwise direction around its pivot axis as viewed in FIGURE 1. Rod 108 receives a sleeve 116 for axial movement therealong and for rotary movement therearound. I form sleeve 116 with a cutout 118 which permits the spring 112 to be snapped over the bar 106. Cutout 118 also permits limited lateral movement of sleeve 116 on rod 108. I form the sleeve 116 with respective tapered cam surfaces 120 and 122 which cooperate with surfaces 124 and 126 on the heads 102 and 104. I so shape surfaces 124 and 126 as to be inclined at the same degree as that to which the surfaces 120 and 122 are tapered, so that the surfaces 124 and

126 contact the cams 120 and 122 along lines of contact.
I form the sleeve 116 with a handle 128 extending radially outwardly from the sleeve. A bore 130 in the handle receives a detent ball 132 which is urged by a spring 134 toward the rod 108. I form the rod 108 with four detent grooves 136a to 136d adapted selectively to be engaged by the ball 132. It will thus be seen that there are four adjusted positions of the sleeve 116 along the rod 108. It will readily be appreciated that each step of adjustment represented by a groove 136 may be a predetermined amount.
For example, in one embodiment each step may be 0.004 inch in the radial direction.
Referring now to FIGURE 8, preferably we form the cover 14 with an opening 138 through which the handle 128 extends. Moreover, we provide indicia alongside the opening so that the user knows which of the adjusted positions is occupied by the sleeve 108.
In operation of our improved currency counter, bills from a stack placed on the tray 16 are fed by the pickers 18 to the nips between the strippers 90 and the feed rolls 22 and
24. The feed rolls and the strippers cooperate to- feed the sheets one at a time along the curved path provided by guide
28 until they reach the nip between accelerator rollers 34 and
38. Owing to the presence of the rib 92, there is no snapping action of the sheets as they are picked up by the accelerator rollers. Moreover, the groove 94 accommodates the rib 92 so that there is no interference with the passage of sheets along the curved guide path.

If for any reason it is desired to change the adjusted position of the stripper shoes 90 relative to the feed rollers
22 and 24, handle 28 is operated to position the sleeve 108 at the desired position. If the user wishes to have this adjustment readily accessible, sleeve 108 can be rotated to a position at which the handle 128 extends outward and through the opening 138. Alternatively, if this adjustment is not to be under the control of the operator, the cover can be removed and the sleeve rotated to a position at which the handle 128 is not accessible as indicated in broken lines in FIGURE 1.
Individual adjustment of the respective stripper shoes 90 relative to the carriers 82 and 84 can be accomplished by means of the set screws 100.
It will be seen that I have accomplished the objects of my invention. I have provided an improved currency counter which overcomes the disadvantages of currency counters of the prior art. My counter eliminates the annoying popping action present in operation of counters of the prior art. I provide my counter with a very precise adjustment of the stripper shoes relative to the feed wheels. This adjustment may be readily either made accessible to the operator or not.
It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of my claims. It is further obvious that various changes may be made in details within the scope of my claims without departing from the spirit of my invention. It is, therefore, to be understood

that my invention is not to be limited to the specific details shown and described.
Having thus described my invention, what I claim is:
