  • Apparatus for dispensing documents typically include a supply of the documents to be dispensed located within the apparatus; some form of feeding mechanism for feeding the documents from the supply, normally individually; and means to transport the documents as they are fed from the supply to some remote issue point such as a slotted opening in the dispenser housing or facade.
  • the dispenser typically includes means to prevent the feeding of more than one bill at a time. If a machine'designed to feed bills on a sequential basis is not prevented from dispensing more than one bill at a time, a user will be given more money than is desired, with resultant loss to the dispensing organization.
  • This objective has been accomplished in accordance with certain principles of this invention by providing, in a currency dispenser having a storage compartment configured to house a vertical stack of superimposed, horizontally disposed bills, the unique combination of a feeder mechanism for horizontally feeding the lowermost bill of the stack, a bill transport for transporting a feed bill upwardly alongside the'stack and thence horizontally back over the stack to an issue point, and a diverter in the transport path above the stack for diverting multiple bills into the storage compartment atop the stack of bills.
  • This invention by virtue of the fact that the bills are fed from the bottom of the stack and thence up and over the. stack past a diverter atop the stack results in an extremely compact dispenser. In effect, the dispenser need not be much larger than the stack itself. Additionally, since the rejected bills are diverted to a point atop the currency stack, it is unnecessary to have a separate hopper or storage compartment located, for example, at some point along a feed path between the stack of currency and the exit point of the bill.
  • Another objective ofthis invention has been to provide a simple and reliable feeder for removing, on a one-by-one basis, bills from the bottom of the stack for ultimate transport to the dispenser exit slot via suitable currency transport means.
  • This objective has been accomplished in accordance with further principles of this invention by, first, supporting the currency stack in the storage compartment in a manner such that approximately 50 percent of the bottom of the stack is unsupported and, hence, exposed from below; second, locating beneath the exposed portion of the stack an agitator mechanism which intermittently engages the exposed portion of the stack, displacing it upwardly on an intermittent basis; and, third, providing a horizontal force to the bottom of the stack in the exposed region thereof.
  • the combination of partial support, upward agitation and horizontal feeding motion serves to flex and separate the bills in a manner which enhances the likelihood that bills will be fed from the stack bottom on a one-ata-time basis.
  • the agitator takes the form of a wheel mounted below the unsupported region of the stack for rotation about a horizontal axis, and a plurality of circumferentially spaced, radially disposed studs mounted in the periphery of the wheel.
  • the studs engage the bottom of the stack as the studs travel in an arcuate path, simultaneously agitating the stack upwardly and applying a horizontal feeding motion to the bottommost bill.
  • This horizontal feeding action of the studded wheel in the preferred form of the invention, is supple mented by a horizontal feed belt which underlies the exposed, unsupported region of the stack for concurrently applying a horizontal feeding action to the bottom bill, supplementing the agitating and feeding action of the studded wheel.
  • This objective has been accomplished in accordance with certain additional principles of the invention by providing a strip ping assembly between the feeder and transport means which includes a rotating lower wheel having a relatively soft friction surface, and a nonrotatable upper wheel into engagement with the lower wheel, which upper wheel has a relatively hard outer friction skin and a relatively soft inner liner, with the coefficient of friction of the outer skin of the upper wheel being less than the coefficient of friction of the surface of the lower wheel.
  • the lower wheel and inner liner of the upper wheel are fabricated of 40 durometer urethane, while the outer skin of the upper wheel is fabricated of durometer urethane. This particular construction has been found to provide excellent stripping qualities while exhibiting a minimum of wear.
  • a further and equally important objective of this invention has been to provide a single bill detector which 'is simple, yet reliable.
  • a bill detector satisfying these requirements has been constructed utilizing first and second magnetically conductive elements located proximate one side of a bill as it is being transported along its path to the exit slot, and a third magnetically conductive element located proximate the other side of the bill opposite the first and second elements.
  • the magnetic coupling between the first and second elements is dependent upon the distance between the third element and the first and second elements, which in turn is dependent upon the thickness of the bill or bills being transported at any given time, which bills pass between the second elements, which can be done utilizing known inductive, or transformer, techniques, it is possible to generate a bill reject. signal when the displacement of the third element from the first and second elements exceeds a predetermined threshold associated with passage of a single bill. This bill reject signal can then be used to divert the multiple bills into a reject hopper or the like.

Also included is a bill feeder mechanism 25 which advances the bottom bill of the stack 12, a stripper assembly 40 which retards the movement of all but the bottom bill and assures the continued advancement of only that bill, and a transport system including belts 43 and 45 which transport a bill from the stripper assembly 40 to the exit 49 along metal plates 37, 57, 58 and 59.

  • the agitator/feeder 26 The theory of operation ofthe agitator/feeder 26 is not entirely understood. However, its success is believed accounted for, at least partly, by the fact that the studs 29 intermittently flex the bills in the bottom region of the stack to effectively break-up the frictional forces existing between adjacent bills, particularly the lowermost two bills, facilitating feeding of the bottom bill. Additionally, the agitating action of studs 29, which intermittently move the stack upwardly an appreciable displacement d, is believed to momentarily take the weight of the stack off the lowermost bill, breaking contact between the bottommost two bills, and thereby enhancing feeding of the bottom bill.

Toothed belt 112 also engages toothed pulleys 160 and 161 keyed to shafts 89 and 158, and drives roll 86 over which transport belts 43 and 45 are trained, thereby driving the belts.
  • the belts 43, 45 via roll 80 over which the belts train, drive transport roll 611 whose liner 1011 is secured to the periphery of roll 80.
  • a toothed pulley 163 rotatably mounted to the end of a bar 164 engages the belt 112.
  • the bar 164 which is slotted to receive a pair of spaced threaded studs 1641a extending from the side wall 9, can be locked in selectively adjustable positions by nuts 16 1b threaded on the studs, adjusting the position of the idler pulley 163 and, hence, the tensioning of the upper drive belt 112.
  • the lower drive belt 113 engages a toothed pulley 169.
  • Pulley 169 is connected to the shaft 35 via an electrically-operated clutch 169a. Keyed to shaft 35 is the roll 34 over which the feed belts 32 and 33 train and to which the friction skin 44 of the lower stripper wheel 42 is secured.
  • driving movement of the toothed pulley 169 imparted by driven toothed belt 113, rotates the roll 34, in turn rotating the lower stripper skin 44 and the feed belts 32 and 33 trained thereon. Movement of belts 32 and 33 in turn rotate the studded agitator/feeder 26.
  • the motor 121 In operation, when it is desired to dispense a bill from exit slot 49, the motor 121 is energized. Energization of motor 121 initiates movement of tooth drive belts 113 and 112 in the direction of arrows 113a and 112a. Concurrent with energization of motor 121, clutch 169a, which selectively interconnects pulley 169 driven by belt 113 with shaft 35 which drives the feed belts 32 and 33 and the lower stripper 12 via roll 34, is energized to initiate motion of the feeding belts 32 and 33 and the lower stripper 12. Movement of the feed belts 32 and 33 rotates the agitator/feeder 26 in a clockwise direction as viewed in H0. 4, initiating feed of the bottommost bill from stack 12.
  • a signal is generated to energize the solenoid 125 of the bill reject mechanism 105.
  • Energization of the solenoid 125 places the combs 106 and 107 in the non-reject position shown in FIG. 5. With combs 106 and 107 in this position, continuing transport action of belts 43 and 45 successively drives the bill over guide plates 57 and 58, the upper surfaces of the combs 106 and 107, and thence over guide plate 59. At this point the leading edge of the bill is sensed by the combination of light source 135 and transducer 136.
  • the bill continues to be transported along guide plate 59 by the transport belts 43, 45 until the bill has passed through exit 49. in the process, the trailing edge of the bill passes between the light source 135 and the transducer 136, permitting the sensing of the trailing edge of the bill. Assuming both the leading edge of the bill and the trailing edge of the bill have been sensed by source l35/transducer 136 in the course of transporting the bill along guide plate 59 and eventually through exit 49, an electrical signal is generated by suitable circuitry (not shown) to again enable the engagement of the. clutch 169a, permitting the bill feeder 25 to feed the third bill from the stack 12 and the stripper wheel 42 to resume feeding the second bill.
  • the electrical signal also deactivates the solenoid to return the reject combs 106 and 107 to their normal reject condition. If both the leading and trailing edge of a non-rejected bill are not sensed by the light source and phototransducer 136 in a predetermined interval, it is assumed the bill has become jammed and the dispenser is rendered inoperative.
  • a reject signal is generated.
  • the reject signal effectively prevents the solenoid 125 from being energized, in turn leaving the combs 106 and 107 in their normal reject position shown in FIG. 4.
  • the partially or fully overlapped bills, as they are transported by the transport belts 43, 45 are diverted into the reject compartment 11b via combs 106 and 107 and drive rolls 115 and 116 upon reaching the bill reject mechanism 105.
  • the light source 119 and phototransducer 120 like light source 135 and photocell 136 at exit 49, function to sense the leading and trailing edge of the rejected bill.
  • a document dispenser for sequentially issuing at a dispenser exit documents initially in a stack, comprising a storage compartment configured to store a vertical stack of superimposed horizontally disposed documents, said compartment having a bottom, and at least first and second oppositely disposed spaced substantially vertical side walls, i
  • feed means disposed proximate said stack bottom to feed the bottom document in said stack in a horizontal direction to advance the leading edge thereof to a first point exteriorly of said first side wall adjacent the lower edge thereof,
