The invention relates to compact apparatus for accumulating and dispensing of bank notes of various length, width and condition without appreciable deformation of current note and displacement of previously stacked notes, preferably having a device connected in series to verify genuineness of bank notes inserted.
Bank notes handling devices are well known and ubiquitous in everyday life. These devices are most often seen in automatic teller machines that can take in paper banknotes and return change, vending and gaming machines that take paper banknotes of various denominations, kinds and sizes. These devices are not only capable of accepting bank notes but also currency keeping, returning or payout (dispensing) of sum required.
Most of handy bank notes dispensing devices comprising primary internal accumulation of note bundle (a little stack of notes) with subsequent its conveyance to customer. So the note stacking mechanism is a common device for note dispensing and note storage apparatus.
Various devices are known for forming stacks of notes. For a long time it is known (U.S. Pat. Nos. 4,052,053; 4,420,153; 4,660,822; 4,728,096; 4,877,230; 4,936,564; 5,163,672; 5,267,826; 5,597,996; 5,975,273; 6,123,327; 6,196,464; 6,276,678; 6,422,458; 6,540,090; 6,824,046) and is widely used in note processing and calculating machines fast-acting rotary stacker. It comprises revolving stacker drum or wheel which has around its cylindrical surface several blades secured at their inner root parts to the drum and extending tangentially in the direction opposite to the drum rotational direction to their outer ends. Notes fed to and entering respective spaces between the blades to be accumulated into a neat stack. Variety of such devices is cash dispensing apparatus (U.S. Pat. No. 6,966,485) with single-gap stacker drum. A cash dispensing unit commonly includes several cooperating endless groups of belts for feeding a stack of bank notes to an exit location. Sometimes a cash dispensing unit is a simple open-sided or open-top cash container. However this drum is large (its diameter is approximate note width) and stacks good-quality notes along their transverse direction. Therefore it is impossible to use such device to stack notes (especially “street bills”) along their longitudinal direction into compact box accumulating and dispensing devices.
The most commonly used stacking box devices (U.S. Pat. Nos. 4,512,263; 4,540,081; 4,678,072; 4,809,966; 4,834,230; 4,858,744; 4,880,096; 5,195,739; 5,209,395; 5,254,841; 5,286,017; 5,322,275; 5,372,361; 5,388,817; 5,419,423; 5,421,443; 5,641,157; 5,662,202; 5,836,435; 6,244,589; 6,585,260; 6,712,352; 6,827,347) are based on transposition method and comprise various pusher plate, pistol, arms, rollers and so on with which a note may be pushed from the plane along which the note is transported to the stacking mechanism (transport plane), into a cashbox situated adjacent to the banknote plane. The pusher transposes the note into the cashbox against the action of a restoring spring and convex notes stack surface. The notes are retained in a stack in the cashbox, when the pusher is withdrawn, by flanges which abut the sides of the uppermost surface of the banknote stack.
Although this type of arrangement provides an efficient method of stacking notes, the required depth of stroke of the pusher is linked to the note width and size of the aperture through which the banknote is pushed. Thus, a short depth of stroke is only possible if the aperture is slightly smaller than note width. The cashbox aperture must be substantially smaller than narrowest note this courses the increasing of pusher depth of stroke. An increased depth of stroke results in an increased cashbox depth for any given size of notes stack and an increased power consumption because of raising of performed work P=F×s (F—averaged force, s—pusher travel). Such devices are relatively slow because of retarded forward trace under which pusher bends the note and shifts the big mass of stacked notes. In order that the flanges should retain the stack of notes, it may be important that the notes are presented for stacking in a predetermined orientation and position. As cashboxes used with such devices often incorporate a restoring spring mounted under notes stack against which a pusher must work, a further problem may arise in such devices. Namely, despite successfully pushing the note into the cashbox, the note may not completely flatten against the stack and may become crumpled causing an interference with next inserted note.
In order to decrease stroke depth and displacement of notes stack certain devices apply a movable flanges in combination with a movable pusher which each move toward the other for pushing of a note received in the guide and adding this note to a stack (U.S. Pat. No. 6,241,240) or a stationary central support (punch) and movable flanges having slots therein adapted for receiving the note inserted thereto (U.S. Pat. No. 6,698,751). The outer support surface is provided with a durable frictional material along lateral edges thereof to prevent the note from sliding or otherwise moving upon the said surface under note banding. Said devices causes strong note banding during stacking process, are relatively slow in operation and have complicated shock unstable constriction. Additionally, it is complicated to thrust “street bill” into narrow long lateral channels in the movable flanges.
U.S. Pat. No. 5,624,017 discloses a compact low power cassette stacker with moveable stacker bars to stacking of bills rather than fixed flanges and a pusher plate thereby achieving an appreciable saving of space and permitting greater stacking capacity for notes. However this device is complicated and can't stacks notes with various width. Additionally, convex surface of notes received in a stacker projects into a bank-note transfer passage interfering with the next processing bill.
U.S. Pat. No. 5,564,691 describes stacking device comprising in a main validator body a pair of bill guide drums rotatably provided along both sides of a down-stream portion of the bill transport passage, each bill guide drum has groove along the axial direction thereof for inserting thereinto side edges of the inserted bill transported though the bill transport passage so that rotation of the pair of bill guide drums in opposite directions moves the inserted bill toward the removable cashbox. Each bill guide drum further has respective inner notches to engage a bill pushing plate provided in a space between the pair of said drums to push the inserted bill toward the received note stack during one drums turn. This device has complicated drums with variable cross-section along note length and belt transport system and can't stocks notes with various width and position across passageway. As stated above, convex surface of notes received in a stacker projects into a bank-note transfer passage interfering with the next processing bill. Additionally, it is hard to separate and to lock the removable cashbox from main validator body. A lot of devices operated similarly above mentioned are described in U.S. Pat. Nos. 5,639,081; 5,887,695; 6,217,021; 6,394,444; 6,543,763; 6,609,661; 6,641,047; 6,708,889. This devices try to avoid said disadvantages by incorporation various pressing levers, arms, rollers, shutters etc. In spite of significant device complication it is impossible as before to stock notes with various width and position across passageway. Furthermore the pressing stage decelerates the device operation and increases power consumption.
U.S. Pat. No. 6,607,189 describes stacking device wherein reception, storage and extraction of the documents are controlled by coordinated motions between a drive roller, a diverter, and special flaps. Said device is complicated, requires a bending of document stack and specified note surface frictional force. It is impossible to use said device for stacking “street bills’ and notes with various length into compact box accumulating and dispensing devices.
Some dispensing devices (U.S. Pat. Nos. 6,032,948; 6,196,457; 6,241,150; 5,247,693; 6,484,938) employing high speed note bundle formation in free space chamber using note motion inertia, additional raping wheels or belts. Said devices commonly includes cooperating endless groups of belts for feeding a stack of bank notes to an exit location. Dispensers of this type are relatively large and can't operates with “street bill” because of its jamming and banding.
It is known (U.S. Pat. Nos. 4,337,864; 4,822,018; 5,735,516) notes bundle accumulating and dispensing devices of rotary or drum type. The notes bundle is accumulated and stored between outer cylindrical surface of rotating drum and driving belts system. The drum is rotated from certain initial position in one direction for storing notes as a bundle, and in a reverse direction of discharging the bundle. A special guide is biased towards the drum to lift sheets off the drum when the drum is rotated in the reverse direction. Said device is characterized by increased energy consumption at the start-stop operational mode, needs the exact speed and phase matching of inserted and accumulated notes, and is relatively slow and heavy.
With the foregoing in view, it is a primary object of the present invention to provide an energy efficient simple compact device for accumulating and dispensing bank notes of various condition, length, width and position in the passageway.
It is a general object of the present invention to decrease power consumption of stacking mechanism.
It is another object of the present invention to enhance durability of note handling units.
It is still another object of the present invention to minimize note banding during stacking process.
It is a yet another object of the present invention to provide a note stacking device which can prevent a note stored in the stacker from sticking out into the note intake passageway and interfering in the processing of the note to be transported next as much as possible.
It is a further object of the present invention to minimize note sticking to stacking mechanism.
The above and other objects and advantages of this invention will become more readily apparent when the following description is read in conjunction with the accompanying drawings.
The invention is based on the idea of inserting note of various lengths, widths and passageway positions into opened spring claw attached to driving belts with simultaneous fast start of belt drive means and gripping of note leading edge by said spring claw. Then gripped note is pulled into temporarily intake due to conveyance of said belts. Said temporarily intake under note inserting and conveyance is formed between driving belts on corresponding pulleys and flat longitudinal revolving panels on side segments of swivel frames. Said panels press the existing notes bundle to spring loaded pallet and so prevent said bundle from sticking out into the note intake passageway and interfering with the currently transported note. Finite phase of insertion procedure is note releasing from spring claw at the end of said intake with note simultaneous breaking by said claw and note stoppage on stop plate. Next stage of note handling is the fast transfer of inserted stopped note to existing bundle by fast pivoting motion on the opposite directions of swivel frames with simultaneous rotation of longitudinal revolving panels under the action of smoothly banded transferred note. The finite phase of note transfer is pressure of note bundle to spring loaded roll pallet by backward pivoting motion of said swivel frames with corresponding simultaneous rotation of longitudinal revolving panels. With this operation completed the temporarily note intake is formed again and device is ready to the next note insertion. Low inertia of belt drive means provides fast driving motor speeding-up and reliable capture of inserted note leading edge. Firm grip of said note end takes away the note frictional sliding across driving belts thus decreases influence of note condition and enhances durability of belt driver. Smooth banding of transferred note longitudinal sides and note bundle shifting motion about 5-6 mm results in low mechanical power dissipation during stacking phase. Slack pressure of banded note to longitudinal revolving panels and their fast relative motion under transferring phase minimizes note sticking to said panels. Pivoting motion on the opposite directions of swivel frames instead of traditional liner pusher shift allows decreasing stacker thickness about √{square root over (2)} times.
Issue of ready note bundle from dispenser is performed by cooperative motion of driving belt coupled with spring loaded roll pallet towards the dispenser outlet gate. Said coupling is performed by roll pallet salient tail arrester meshing with claw on inlet pulley under one-way fast pivoting motion on the opposite directions of swivel frames. After note bundle withdrawal said spring loaded roll pallet at said coupled state returned to initial position due to reversing motion of said driving belt.
Also provided, in accordance with preferred embodiment of present invention, is a method for note stacking including note insertion into note entering slit, fast start of belt drive means with simultaneous gripping of note leading edge by spring claw, note drawing into note temporarily intake, note releasing from spring claw at the end of said intake with note simultaneous breaking by said claw and note stoppage on stop plate, fast note transfer to existing notes bundle by fast pivoting motion on the opposite directions of swivel frames with simultaneous rotation of longitudinal revolving panels, pressing of note bundle to spring loaded roll pallet by reversible pivoting motion of swivel frames with corresponding simultaneous rotation of longitudinal revolving panels.
In dispenser embodiment method further comprises note bundle and spring loaded roll pallet pressure to belt drive means under one-way fast pivoting motion on the opposite directions of swivel frames with longitudinal revolving panels, fast start of belt drive means with simultaneous coupling of salient tail arrester of spring loaded roll pallet with belt claw, opening dispenser outlet gate, moving out of note bundle clumped between spring loaded roll pallet and belt drive means, backward moving of swivel frames with longitudinal revolving panels for pressure to spring loaded roll pallet and holding in dispenser the notes bundle rear part, return of belt drive means with spring loaded roll pallet to initial position after notes bundle withdrawal from dispenser.
In note accumulator embodiment method comprises note insertion into note entering slit, fast start of belt drive means with simultaneous gripping of note leading edge by spring claw, note drawing into note temporarily intake, note releasing from spring claw at the end of said intake with note simultaneous breaking by said claw and note stoppage on stop plate, fast note transfer to existing notes bundle by fast pivoting motion on the opposite directions of swivel frames with simultaneous rotation of longitudinal revolving panels, pressing of note bundle to spring loaded roll pallet by reversible pivoting motion of swivel frames with corresponding simultaneous rotation of longitudinal revolving panels, one-way fast pivoting motion on the opposite directions of swivel frames with longitudinal revolving panels for note stack pressure to belt drive means by spring loaded pallet. At that note storage in keeping position is performed without loading of movable stacking mechanism up to next note insertion to validator or notes withdrawing from cashbox.
Further provided is a method for note redirection comprises note insertion into note entering slit and note conveying to dispatcher or next accumulating device throw note directional switch wherein the commutation of said switch is performed by spring claw on belt drive means under its appropriate position at the driving pulley. Under subsequent note drawing edgewise to the temporarily intake chamber.
Still further provided is a method for driving means braking and exact positioning including note braking at the end of note intake by slow brake mode with recuperation of mechanical energy and stoppage of spring claw at the driving pulley by exact positioning mode.
Several embodiments of the present invention will now be described by way of example with reference to the accompanying drawings.
Preferred embodiments of the invention are shown in the drawings, wherein:
The note handling apparatus shown on
The bank note removable storage stacker 4 is designed to receive bank notes which have been previously accumulated and forwarded to the stacker from one of the accumulators 3 along path 602. Thus, the drive paths 209, 501-505, 601, 602 are by-directional. A received just now bank note can also be directly processed to the removable banknote storage stacker 4. In this case the banknote is not returnable to the pathway and is removed from the apparatus when the storage stacker is removed.
The note dispenser 2 in accordance with the preferred embodiment of the present invention comprises plastic case 201 with outlet port 212 locked by gate member 202, note stacking means 204, note transfer means 205, note directional switch 206, input sensor 206, stop sensor 207 and note withdraw sensor 211. Said gate valve 212 is in cooperative coupling with spring loaded roll pallet 203 in order to open said gate under note bundle 210 moving out. Structure of note stacking means 204, note transfer means 205 and note directional switch 206 will be described in details below.
The removable note storage stacker 4 comprises lockable metal-plastic case 401 with door 407 and lock 408, note stacking means 402, note pallet 403 with restoring springs 404, note transfer means 411 with two spring claw 405a and 405b at the opposite sides of driving belt, input sensor 406 and stop sensor 409. Construction and operation of note transfer and note stacking means at note dispenser 2 and note stacker 4 is a similar. The said storage stacker 4 is removable from the apparatus and a replaceable bank note stacker is easily inserted or said stacker can be emptied and reinstalled.
The temporarily bank note accumulators 3a-3d are of an identical design and are replaceable, one with the other. Said accumulators form an opposed pair appropriately positioned on opposite sides of the pathway 601 and pathway 602. Banknotes forwarded from the validator 1 move downwardly through passageways 209, 601 and the validator 1 provides information with respect to the denomination of the particular bank note received and accepted. Bank note accumulator 3a may accumulate $5.00 bank notes, accumulator 3b may accumulate $1.00 bank notes, accumulator 3c may accumulate $10.00 bank notes and accumulator 3d may accumulate $20.00 bank notes as one example. The apparatus can be programmed to change the denomination of the bank notes stored. In the case of gaming machines it may be desirable for one accumulator to store large denomination bills which can be dispensed if there is a large payout. It is also possible to use one of the bank note accumulators, such as accumulator 3a as an escrow accumulator. For example, a user might enter several bank notes into the validator for a particular transaction and these bank notes are fed from the validator to the escrow accumulator 3a. The apparatus keeps track of the number of bank notes fed to the accumulator and the value thereof. If the transaction is terminated, either due to insufficient funds or based on instructions from the user, the same bank notes received from the user and stored in the escrow accumulator 3a are sequentially returned to path 601 and transported upward to the dispenser 2 throw diverted note directional switch 209. The dispenser 2 receives the bank notes from the escrow accumulator, stacks them one atop of the other and dispenses the note bundle through port 212. In this way, the identical bank notes are returned to the user.
