device for storing and individual dispensing of banknotes

The invention relates to a device for storing and individually dispensing bank notes.

Automatic counting machines / those taking their many punctures also include the distribution of banknotes to the recipient are known. Banknobe.a have very different Properties due to age, country, nature, environmental conditions, etc. These different Properties between currency types based on denomination and country and between individual banknotes within of a currency make it extremely difficult to design a single device, all types of banknotes and all Can process (store, separate, transport) banknotes of a given type.

State-of-the-art automatic counting machines for distributing means of payment dispense prepackaged bundles of banknotes. While these machines the difficulties over-Iwinden associated with the processing of banknotes with very different characteristics, they do not have the flexibility to spend cash in any amount that ^one is divisible by the denomination of the currency issued.

Other prior art automatic machines for distributing currency have devices for Separating the individual banknotes from a stack that is in

a container has been loaded. Many methods of separating banknotes, including suction, are in State-of-the-art cash distributors been. One of the most reliable works with a friction separating belt to separate a document from the Pull off the end of the stack, and a reverse drive belt, which prevents the second from the top Banknote with the top one being issued. Such a dispensing device is described in U.S. Patent 3,937,925. Such j currency distributors require the loading of loose stacks of banknotes, in devices that are often far away from the security area Bank are arranged, which requires that the means of payment by people transported there and correctly in the hopper of the Device.

It has been suggested that bills be loaded into semi-secure bins for distribution from a bin loading station to the remote automatic counters and that the bills be removed from the bin as individual sheets for delivery to the automatic counter operator. A serious problem with this has been difficulty to remove the individual sheets from such a container without disturbance in the container or without transportation outside the container and without multiple sheets sticking together. Another serious problem arises when, in the course of removing one of its sheets from such a bin, subsequent sheets already extend somewhat through the output door or the output slides for subsequent removal and do so when it is desired to have the bin off the automatic counting machine remove. The partially peeled sheets can then remain in the transport device of the automatic counting machine or can easily be fraudulently removed from the container.

The problems mentioned were only mentioned as representative of the many problems associated with processing banknotes or

Such a delivery operation is made by the OR slied 31 prevents, if the switch 156 signals that pine cassette with the correct denomination is open when the The dispensing opening 76 is not in its place, or when the sensor 122, which indicates the lack of cash, is addressed has what will be described in more detail. The control device 21 also responds to a signal from the sensor 120, the only reports a low supply of cash to signal the need for maintenance of the cassette 20. !

The motor 27 drives the separating belt 54 in the interior of the cassette via the coupling 23 and 228 and the motor 25 via The clutch 272 and the inhibitor belt 62, which will be described in more detail will.

JFig. 2 to 4 refer to the cassette whose (Housing 20 from an upper and a lower wall and the

Side and end walls are made to enclose a stack 40 of banknotes. The stack 40 is within the The cassette 20 is held securely by the upper guide rails 46, the side guide rails 48, 50 and the support plates 52 for the documents, the feeder assembly 22, the device 30 for counting the documents and the separating belt The side guide rail 48 is fixedly connected to the cassette housing 20 and the side guide rail 50 with it the closure cover 64 and the size of the documents 40 adapted for which the cassette is designed.

The document platen 52 is fixed to the bottom plate tied together. This is wedged in order to be in projections 58 of the Housing 20 to engage and snap into place over pin 6O so that bottom plate 56 can be removed to release the escapement strap 62 to be exposed for maintenance purposes.

The closure cover 64 is part of the top wall and a side wall of the cassette housing 20. Cranked projections of the closure cover 64 engage elongated holes 68 of the housing 20 to form a hinge about which the closure cover 64 can be rotated to open the cassette 20 for document loading or unloading and for maintenance purposes. Lugs 70 are attached to the closure lid, which will be explained in more detail. The handle 74 is attached to the closure cover 64 for the transport of the Cassette to and from the associated device.

Documents are fed through the slot 76 in the lower wall of the cassette 20 to a conveyor for delivery to the Customer supplied »

The stack of bills 40 is supported by the document carrier 78 pressed against the separating belt 54. The document carrier 78 is moved by a spring 80 with constant spring force, which is assisted by the force of gravity emerging from the Angle results at which the cassette 20 is attached to the base of the housing 38 relative to the horizontal. the Spring 80 with constant spring force is wound around the shaft 82 of the feeder 22, lies on top of the base plate 56 and is attached to it by screw 84. The spring 80, which has a constant spring force, has the property that regardless of the horizontal distance between the shaft and the fastening screw that exerted by the spring 80 Force which presses the shaft 82 in the feeder 22 against the separating belt 54 is essentially constant. The document j Carrier 78 is attached to frame 86 on which wheels 88 are rotatably mounted. The wheels 88 run in a track between the! (Bottom plate 56 and the surface 90 of the document carrier plate 52 I and thereby allow the movement of the feeder 22 along ' the longitudinal axis of the stack of documents.

he the friction of the document stack 40 on the document carrier plate 52 compensates, reaches the constant spring force having spring 80 that the document carrier urges the stack of documents 40 against the separation belt 54 with a force that is substantially constant and independent on the number of documents in the batch is 40. Also, the material for the document support plate 52 is chosen so that the frictional force between the document support plate 52 and the documents 40 is substantially constant over a wide range Range of environmental conditions (including document material, temperature, and humidity). These Conditions are essentially met by using an acetate homopolymer as the friction surface of the document support plate 52 and by choosing an angle 33 from 12.

Reference is made to FIGS. 3 and 10 below. Magnetic field generators 110, 112 are on the document carrier fastened by screw 114 so that they pass a path along the inside of the rear wall of the cassette housing 20, when documents of the stack 40 are output and the feeder 22 moves on the separation belt 54. River concentrators Metal pieces 116 and 118 are mounted in the rear wall of the cassette 20 along this path and operate with magnets 110 and 112 together to make the hall effect sensor 120, 122 to activate the generation of signals that report a low and an exhausted supply of money. One The condition referred to as an exhausted cash supply is when the stack 40 no longer contains enough documents to an expected transaction to be completed and a condition known as low cash is when the stack is so low that maintenance personnel should be advised to replace the supply or the cassette to exchange for another.

The Hall-effect sensors 120 and 122 are attached outside of the cassette 20 in the machine frame so that they can with the Flußkonzen-

indicating signal. The Hall effect sensor 120 remains on (due to its inherent hysteresis and the
Field of the magnet 110) until the magnet 112 reaches the flux concentrator 116 and the Hall effect sensor 122 switches on. The distance between the concentrators 116 and 118 is greater:

than the distance between magnets 110 and 112. However, i

In connection with FIGS. 2 and 3, the document counter 30 is described, which is located on the front panel 204 by the Screw 206 is attached. In the vertical direction it is adjusted so that the surface 210 of the counter finger 208 is extending slightly lower than the top of the stack. Document skew influencing guides 212 are so arranged on both sides of the upper end of the stack 40 that they prevent the misalignment of the Dokuriente when this extends beyond the document support plates 52 and through the narrowed guide 214 between the separation belt 54 and the Escapement strap 62 arrive. As the documents are ejected from the cassette, the pressure difference between the Documents that press against surface 210 and those closer to separation belt 54 until it is sufficient that (a few documents beyond the area 210 into the distribution area fall under the guides 212 influencing the misalignment. In this way, the pressure on the JDocument 42 does not grow excessively, which would make it difficult to move the top document 42 from the next Document 44 can be separated by the cooperation of the separating strap 54 and the escapement strap 62.

The cassette contains the separation belt 54, which is driven by the drive pulley 216 and from the idler pulley 218 is worn.

Alternatively, the separating belt 54 can be part of the transport device 29 and extend through a door, not shown, into the cassette when it is in place is located. The drive pulley 216 is on a shaft

The faceplate 204 is j sized to fit into cassette 20 and is also held in place by the tension of belt 54. j Otherwise fastened by screws (not shown).

) the escapement belt 62 is moved by the pulley 234 in the direction of the tension vector 236 via the tensioning rollers 238, 240, 242 and 244. The tension rollers 240, 242 and 244 are mounted on the inhibitor arm 246 by means of shafts 248, 250 and 252. The jam arm 246 is rotatably mounted to rotate the shaft 60 in the cartridge wall 20 and is urged by the leaf spring 256 in the direction of the arrow 254 to press the jam belt 62 on the roller 244 against the separation belt 54. The] 51attfeider 256 is firmly connected to the inhibiting arm 246 on the holder 158 and is pressed against the reaction pillar 260 in the cassette housing 20 by spring force.
