Description

The invention relates to techniques for the automated reception of banknotes. Machines for receiving banknotes are widely used when accepting cash from organizations and individuals. A user who passes notes identifies himself with a bank plastic card, password and / or biometric parameters of his body. Then, the machine, through the user interface, asks to place the banknotes in the receiving pocket or in the receiving slot, then moves them into its housing, checks them for solvency, and then stores them in the drive for the received money. A banknote or several banknotes deemed insolvent are returned to the user either through the receiving pocket or slot, or through a special pocket or slot for rejected banknotes. Information about banknotes received from the user and placed in the drive is transmitted by the machine to the processing data center serving this machine. As a result, funds received from the user and deposited in the drive for received money are credited to the user's bank account, or are counted as payment for any service or product.

According to the principle of accepting banknotes, such machines are divided into machines with a bill accepting method, or with a bundle method. In machines with an up-and-coming reception, only one banknote can be placed in the receiving slot, which is further processed by the machine, and only after processing it can the user pass the next banknote. In machines with a bundle, a bundle of banknotes is inserted into the receiving pocket or slot. Then, the machine divides the bundle into single banknotes, which are then processed individually. Machines with a pack reception have a higher productivity, and are used where the user needs to deposit a large number of banknotes.

When using machines for receiving banknotes, a stable practice has developed with regard to the interpretation of the right of ownership for banknotes being handed over. Banknotes located in all parts of the machine, except the drive for received money, are considered to belong to the user. Banknotes transferred to the drive for received money belong to a bank or other financial institution that is the operator of the machine and is responsible for it. The process of receiving banknotes, therefore, is interpreted as the transfer of ownership of banknotes from the user to the operator of the machine, which is accompanied by the simultaneous transfer of non-cash funds in the same amount from the operator to the user. In case of various malfunctions in the operation of the machine, they try to immediately return to the user all the banknotes that are in the machine outside the drive for received money in order to avoid financial claims. Obviously, the most important operation from the point of view of transferring ownership of banknotes is the mechanical transfer of banknotes into the drive for received money. The financial reliability of the machine is largely determined by the absence of failures during this critical operation.

From the point of view of components, banknote reception machines usually refer to systems, because in them the drive for received money, as a rule, has a removable capacity in the form of a cartridge or bag. Such a container is filled with banknotes as the machine operates, and then, during collection, it is removed from it and replaced with an empty container of the same type. The filled capacity is transported to the cash settlement center, where banknotes are removed from it and counted. The empty tank is reused in the machine. In the patent literature often do not pay attention to the removable nature of this capacity, and call the described machine a device for receiving banknotes.

The drive for received money may contain more than ten thousand banknotes, which attracts criminals. As a rule, the drive itself is enclosed in a safe with a high degree of protection, breaking it requires considerable time and special technical means. However, in the wall of the safe there is always a weakly protected opening through which the banknotes move into the drive. If this hole is large, then the criminals manage to steal significant amounts of banknotes through it in a short time without breaking the safe. Therefore, reducing the size of the holes in the safe is an important technical task. An ideal type of hole is a slot so narrow that it would still be possible to pass a banknote into the bank, but it would be difficult to extract a substantial amount of banknotes from the bank through this slot. In reality, taking into account the dimensions of the necessary elements of the banknote path, we can talk about the minimum achievable slit width equal to one or several millimeters. Such a gap provides a sheet-like movement of banknotes. Through it, even with the use of special devices, the offender can get banknotes only in sheets, which sharply reduces the financial attractiveness of the attack.

In machines for receiving banknotes, it is usually necessary to realize the return of a banknote or several banknotes at the request of the user, before they are transferred to the drive for received banknotes. This function is implemented with the help of the so-called temporary storage device, which is commonly called “escrow” in international terminology. Banknotes are placed in the temporary storage device after the successful completion by the machine of a check of their solvency. From a temporary storage device, banknotes can either be transferred by the machine to the storage device for received money, or the machine must return them to the user. Thus, the critical operation of transferring ownership of banknotes is performed as, moving banknotes from a temporary storage device to a storage device for received money.

The invention relates to a temporary storage device for use in machines with a bill accepting package. All known designs of temporary drives can be conditionally divided into drives with direct user access, and internal drives to which user access is not provided. Most often, internal drives are used. An internal temporary storage device is built into the banknote path of the machine and provides two types of actions: receiving banknotes from the path to the drive, and issuing banknotes from the drive to the path. By their design, internal temporary storage devices are almost identical to cassettes for receiving and issuing banknotes, which are used in ATMs with a cash turnover (recirculating ATMs). Two principles are widely applied: roll storage and pack storage.

An example of a roll drive can be found in patent RU 2491642, 08/27/2013 IPC G07D 11/00. In this drive, banknotes are received from the path and clamped between two layers of thin polymer tape that are wound onto a drum in the form of a roll. To issue banknotes, the layers of the tape are wound from the drum, as a result of which the banknote between them is sequentially released from the roll and removed from the drive into the path.

An example of a pack drive is the device described in patent RU 2638133, 12/11/2017, IPC G07D 11/00. It has a single port for receiving and issuing banknotes, and a box for storing a bundle with a motorized drive of the moving bottom. Received banknotes are introduced through the port parallel to the bottom surface, and are attached to the bundle using a wheel with flexible blades. This wheel provides a sliding movement of the banknote over the bundle, so that it does not have the ability to rest against the other banknotes already in the bundle and get stuck. For issuance, a friction sheet mechanism is used, directing the extreme banknote in the bundle to the port and blocking the movement of the remaining banknotes. The movable bottom moves with a change in the number of banknotes in the bundle, providing the necessary free clearance of the extreme banknote in the bundle when receiving the banknote, and the necessary effort to press the bundle against the friction laminating mechanism when issuing. Bundle devices provide large capacity and small dimensions, but have a complex mechanism and control algorithms.

Let us consider in more detail the structure and operation of the shearing mechanism. It is designed to separate banknotes from the bundle and sheet feed them into the banknote path. Flashing mechanisms are widely used in various banknote processing machines. So, in counters and sorters, the folding mechanism leafly sends banknotes from a bundle located in the input pocket to the detection unit, which scans the banknote, determines its currency and denomination, and also verifies authenticity. In ATMs, the folding mechanism is used to issue single banknotes to the path from the stack located in the cassette. In addition, if the ATM implements the function of the packet reception, then the leafing mechanism is used to separate the bundle placed by the user in the receiving pocket into single banknotes. In general, the folding mechanisms are used in the technology for processing a variety of sheets, which includes not only banknote processing devices, but also printing machines, printers, and copy machines. According to the physical principle of operation, most of the used folding mechanisms are frictional, that is, they use friction force to move and separate banknotes. Some flashing mechanisms use a vacuum, they are rarely used and will not be considered here.

The friction sheet mechanism comprises advancing surfaces as well as stopping elements. The moving surface, which is in motion, is pressed against the extreme banknote in the bundle and, due to the friction force that has arisen, shifts this banknote from the bundle towards the banknote path. Due to the frictional force between the sheets in the bundle, the extreme banknote carries with it one or more neighboring banknotes, which we will further call attached. To ensure a sheet feed, attached banknotes cannot be allowed to enter the banknote path. For this, a stopping element is placed opposite the advancement surface so that the banknote passes between them. The restraining element comes into contact with an extreme banknote or an attached banknote, if any. Due to the frictional force, the stopping element stops further advancement of the attached banknote, but it should not interfere with the moving surface to bring the extreme banknote into the path. For this, it is ensured that the friction force between the banknote and the advancing surfaces is higher than the friction force between the banknote and the restraining elements, and both of these forces would be greater than the friction force between the banknotes. When the end note is sandwiched between the advancing surfaces and the restraining elements, the total force advances the bill in the direction of the bill path. When a packet of an end and attached banknote is caught between the advanced surfaces and the stopping elements, the extreme banknote moves together with the advancement surfaces, the attached banknote is stopped by friction against the stopping elements, and a slip occurs between the extreme and attached banknote. The configuration of the delaying element is selected so that it touches the edges of the banknotes and can stop not only one but also several attached banknotes in the bag.

There are many known design solutions sluzhivaya mechanism. Some of them use a fixed stop element. As a rule, the difference in the frictional forces needed to delay the attached banknote is achieved due to different coefficients of friction on the paper for the materials of which the advancement surface and the retention element are made. For example, in US patent US 5,102,116, 04/07/1992, IPC B65H 3/52, the moving surface of a rotating rubberized wheel and a fixed concave-shaped retaining element are used. Between the restraining element and the advancing surface, a small pressing force is created due to the weight of the restraining element. In US patent US 5,335,899, 04/14/1994, IPC B65H 1/02, both the surface of the rubberized wheel and the surface of the belt are used to advance the sheet. The stopping element is a fixed protrusion of the tract, opposite which there is a stretched belt. The clamping force is provided due to the deflection of the belt, but the belt itself does not come into contact with the stopping element. In the patent RU 2171769, 08/10/2001, IPC В65Н 3/00, an advancement surface in the form of a belt is also used, and the stopping elements are fixed rollers. There is no contact between the advance belt and the retention rollers, and the force of pressing their surfaces against the paper is achieved due to the elasticity of the deformed sheet. In the described solutions, the stopping element may touch the advancement surface (as in US 5,102,116), or contact between the delaying element and the advancement surface is excluded (as in US 5,335,899, RU 2171769).

There are also solutions in which the restraining element is made in the form of a movable surface, creating a normalized force applied to the sheet and aimed at returning the attached banknote to the bundle. This force is created using a belt, as in US Pat. No. 4,978,114, 12/18/1990, IPC B65H 3/04, or using a roller, as in US Pat. No. 5,006,903, 04/09/1991, IPC B65H 3/04, driven separate brake engine. The holding force here is determined not by the coefficient of friction, but by the normalized torque of the brake engine. Such solutions do not imply slipping of the retaining element relative to the surface of the sheet. When a single banknote passes through the lamination unit, the brake motor rotates in the direction opposite to its torque.

In leafing mechanisms, which are used in temporary storage units of the pack type, use a motorized clip of the pack to the moving surface. This achieves the operation of the folding mechanism at the optimum values of the friction forces, in order to exclude the supply of double banknotes or delayed folding. However, in other types of banknote processing machines, such as counters and sorters, motorized clip tacks are very rarely used. As a rule, in these machines high-quality flipping is achieved by pressing the banknote against the promoting element by weighing the banknote itself or a bundle of banknotes.

It is possible to conditionally divide laminating mechanisms into continuous and periodic. If the advancement surface is uniform and moves continuously, then such a folding mechanism feeds banknotes continuously, at a constant speed and with almost no gaps. Examples of a continuous mechanism are given in US 5,102,116. The estimated performance of the continuous mechanism, in banknotes per second, can be obtained by dividing the linear velocity of the moving surface by the size of the banknote in the direction of folding. In the patent RU 2484001, 06/10/2013, IPC B65H 7/06, an example of a flapping mechanism is described, where the advancing surface has the form of sector friction linings on a rotating flaking roller. This folding mechanism feeds banknotes periodically, once per revolution of the roller, when the friction lining comes into contact with the banknote. The estimated performance of the periodic sizing mechanism is equal to the number of revolutions of the sizing roller. The actual performance of the peeling mechanism is usually somewhat lower than the calculated one, since sometimes the promoting surface cannot immediately feed a banknote, and a skipping skipping occurs.

The issuance of banknotes from the internal drive to the path is used both when moving banknotes to the drive for received banknotes, and when it is returned to the user. This organization of the machine determines the high complexity of the banknote path and the entire mechanism as a whole. In order to implement both types of operations (moving to a drive for received money or returning to the user), a branched path equipped with an electromechanical redirection element is required. The return to the user of a bundle of banknotes requires an additional, rather complex unit for forming and / or issuing the bundle from the machine. Using an internal temporary storage device not only leads to high complexity and cost of the machine, but also increases the likelihood of banknote jam when moving through a branched path and when forming a bundle for return. That is, the probability of failure during the critical operation of transferring ownership of banknotes increases, which reduces the reliability of the machine and entails additional difficulties for both the user and the operator organization.

To solve this problem, the design of the machine is further complicated to reduce the likelihood of failure at each node. An example is a banknote processing machine described in US Pat. No. 7,487,874, 02/10/2009, IPC B07C 5/00. It uses a pack-in temporary storage device, separate pockets for receiving and issuing banknotes in a bundle, a complex banknote path with a looped structure and many redirection elements, and several cassette drives for received banknotes. Due to the looped structure and backup use of drives, the machine remains operational even with some jams in the banknote path. The machine also provides the function of issuing banknotes from certain cassette drives. The scope of such machines, due to their complexity, is limited by locations with large amounts of daily processing of banknotes.

As an alternative to an internal temporary storage, direct access storage devices are known in the art. Such a drive combines the functions of both a temporary drive and a unit for forming and issuing a returned packet. A key element of a direct-access drive is a pack driver. When it is necessary to accept a banknote in a temporary drive, the shaper attaches it to the bundle formed inside the drive. When it is necessary to return a pack from the drive to the user, then access to the pack is opened to the user from outside the machine. To do this, open the barrier that previously hid the drive from the user. This approach is simple and reliable, since it does not require any mechanism actions on banknotes to return them. After opening the barrier, the user only has to manually remove the bundle of banknotes from the drive. Actually, the name “drive with direct access” is conveyed by the fact that, when the obstacle is opened, the user gets full visual and tactile access to the pack and can pick it up from the car.

The movement of banknotes into the drive for the received money is the only type of movement from a temporary drive with direct access, which must be implemented by the machine mechanism. Therefore, there is no need for branching the path of movement of banknotes, and this path itself can have a simple design with a small number of elements. In this description, we will use the term “transportation route” to denote the way of transferring banknotes from a temporary storage device with direct access to the storage device for received money. Thus, the transportation path is different from the banknote path, which provides the movement of banknotes between the remaining nodes of the machine for receiving banknotes.

Historically, the first known direct-access drives for moving banknotes use the free fall of banknotes under their own weight. As a bundle former, they use a stacking mechanism with a wheel equipped with curved blades, which was entirely borrowed from the banknote counter. An example of such a stacking mechanism is shown, for example, in US patent US 9,695,005, 04/02/2015, IPC B65H 33/00. A stack in such a stacker is formed from banknotes in a vertical or close to vertical position. The thickness of the bundle is limited by the width of the pocket of the drive, and the stacking mechanism is functional only when there is no noticeable compression between the banknotes in the bundle. Due to the lack of compression, and the non-flatness of real banknotes, the width of the bundle turns out to be much larger than could be obtained by multiplying the banknote thickness by the number of banknotes. Therefore, the structural width of the drive’s pocket is usually several tens of millimeters.

Consider how the transport route is implemented in the above patent. To move banknotes into the drive for received money, the bottom of the pocket, on which the bundle rests, is movable and can be moved outside the pocket by an electric drive. Directly below the moving bottom is a hole leading to the drive for received money. This drive is made in the form of a so-called free fall bag or a free fall box placed in a safe. Banknotes are transferred to the accumulator for received money under their own weight. We will call this type of drive gravitational. The described design is simple and high speed, because, even in the case of a large bundle of banknotes, the fall process is completed in a few seconds. The user’s access to the temporary storage pocket necessary to return the bundle of banknotes is limited by a sliding door with a motorized drive, such as that described in the aforementioned US patent 9,695,005. This door is located on the side of the front wall of the pocket facing the user.

The design of the temporary free fall drive shown here, in various versions, is represented by the products of many manufacturers and can be considered well known. As far as the authors were able to establish, it belongs to the public domain and is not subject to patent protection.

The main disadvantage of the described design is the need for a large inlet of the drive received money. To ensure that all banknotes fall inside the drive without being stuck, you have to make the width of this hole equal to the width of the pocket, that is, several tens of millimeters. Due to such a large size of the hole, machines of this design often become the target of robbers who can get banknotes out of the safe in a short time and without complicated devices. As a protection measure, the opening in the safe is sometimes covered with an additional sliding door made of relatively thin metal. However, experience has shown that this door can be quickly removed using a simple tool. As another measure of protection, attempts were made to establish, directly behind the inlet, a labyrinth barrier preventing direct access to the contents of the drive for received money. Unfortunately, such a labyrinth fence is often clogged with freely falling banknotes, and the car crashes.

The temporary storage device described here is designed to work with gravity storage devices for received money, operating on the principle of free fall, moreover, the banknotes fall into the storage device in a vertical orientation or close to it. The main disadvantage of this type of gravity storage device is the low density of banknote stacking, due to the chaotic arrangement of banknotes in it. With a low packing density, the drive requires a very large size to ensure high capacity.

A special combination of a temporary storage device and a gravity storage device for received money is known, devoid of such a drawback. It is described, for example, in Japanese patent JP 3868677, 03.16.2001, IPC G07D 11/00. Both in the temporary storage device and in the storage device for received money, banknotes in horizontal orientation are stacked. When moving from a temporary storage device, a stack of banknotes, without changing orientation, falls into the storage device for received money and joins the foot already in it. This special combination has two drawbacks. Firstly, the free fall of one stack of banknotes to another while maintaining a horizontal orientation is possible only for hard banknotes that are almost wear-free and have a high degree of flatness. A similar state of banknotes in circulation is characteristic of Japan, and is almost never found anywhere else in the world. If the banknotes do not have rigidity and flatness, then when the foot falls, it often turns and / or crumbles, which leads to malfunctions of the device. Another disadvantage is associated with the very large size of the hole through which the banknotes are fed into the store for received money. Such a hole should have a size slightly larger than the size of the largest banknote. This makes penetration into the drive through the hole very convenient and attractive to criminals. Therefore, in practice, the described special combination is almost not used, and in gravitational storage devices, banknotes are dropped in a vertical or close orientation.

In the prior art, various drives for received money are known in which banknotes are forcibly, sheet by sheet, stacked using a special stacking mechanism. Compared with gravity storage devices with falling banknotes in a vertical orientation, they provide a high banknote density due to the ordered arrangement and small gaps between the sheets. Unlike the special combination indicated above, a drive with forced sheet laying in the foot can securely stack banknotes of almost any quality. Such a drive is described, for example, in US patent application US 2018137712, 05.16.2018, IPC B65H 29/50. In it, banknotes are sent to the cassette drive one at a time, and enter the gaps between the curved blades of the stacking wheel. When the stacking wheels rotate, they abut against a stationary ejector and are pushed out of the gaps, and then lie in the stack that accumulates on the moving bottom of the drive. The bottom has a motorized drive that moves it away from the stacking wheel as the foot grows.

For forced sheet laying in the foot, banknotes must be submitted one at a time. Therefore, accumulators for received money with forced sheet laying of banknotes in the stack are used together with temporary stack or roll type accumulators, which were briefly described above. This limits their use by banknote machines of increased complexity. In simpler machines for bundled reception of banknotes, gravitational drives are used with falling banknotes in a vertical orientation, which determines the low density of banknotes and the increased dimensions of these devices.

In US patent US 9,311,765, 05/12/2011, IPC G07D 9/00, a special transport mechanism is used instead of the principle of free fall to transfer banknotes from a temporary storage device to a storage device for received money. It is a grip that tightly compresses the bundle formed in the temporary drive and pushes it through the drive inlet for received money. Further movement of the pack in this drive is already under its own weight. Due to the fact that the pack is pushed through the hole in a tightly compressed form, the width of the hole was significantly reduced. This width, as experience shows, should be at least 15 millimeters for every 100 banknotes of a pushed bundle. So, for a pack of 200 banknotes, you need to have an opening at least 30 mm wide. This turns out to be a significant improvement in protection against criminal access to banknotes, in comparison with those machines where only free fall is used. Nevertheless, the hole width of 15-30 mm leaves criminals with the opportunity to grab and pull out small bundles of banknotes using specially made devices. As already mentioned, from the point of view of security, the leafy movement of banknotes into the drive through a slot with a width of one millimeter or several millimeters can be considered optimal.

Another drawback of the aforementioned temporary storage device is the increased likelihood of failure when transferring a stack of banknotes to the storage device for received money. The fact is that the formation of the pack in the drive occurs under the influence of gravity. After being pushed out of the gap between the blades of the stacking wheel, the movement of the banknote occurs exclusively under its own weight or under the influence of other banknotes in the bundle. For various reasons, sometimes a malfunction of the stacking wheel occurs when the banknote does not fully enter the bundle or does not enter the bundle at all (for example, it rests on top of the bundle edge). This often happens due to the banknote entering the stacker wheel with a significant skew, or when the banknote loses its stiffness and / or flatness due to wear. Bundle capture works correctly when the banknotes in the bundle are stacked evenly. When the bundle has an irregular shape, when it is transferred to the accumulator for received money, a jam or damage to the banknote may occur. A banknote not attached to the bundle, after moving the bundle, may remain in the pocket of the temporary storage device. The design of the temporary drive provides a vision system that allows you to notice the incorrect formation of the pack. This complicates the device and avoids a critical failure, but, however, cannot ensure the movement of an improperly formed packet.

Banknotes in the said device fall into the gravity storage device for received money in the form of a tightly compressed bundle, in an orientation close to vertical. As it falls, the bundle crumbles into separate banknotes, which are randomly stacked in the lower part of the drive. Therefore, the described device is characterized by a low density of banknotes in the drive for received money, which requires an increase in the volume of this drive. This drawback, as already mentioned above, is characteristic of all decisions where banknotes fall into the gravitational accumulator in a vertical orientation.

US patent 9,311,765 was selected as a prototype of the claimed invention. The technical result of the claimed invention is safer, from the point of view of protection against criminal access, pairing a temporary drive with a drive for received money. An additional technical result is a higher reliability of transferring banknotes from a temporary storage device to a storage device for received money.

These results are achieved due to the fact that the temporary banknote stacker contains a pocket for temporary storage of banknotes formed by the front wall, back wall and bottom, a door from the front wall side to prevent access to the pocket from the outside, a banknote stacking wheel equipped with curved blades, a stationary banknote ejector providing pushing banknotes from the gap between the blades of the stacking wheel as the wheel rotates, and a transport path for transferring banknotes from the temporary storage pocket to the drive l for accepted banknotes, wherein the entrance to the transport path is located between the back wall and the bottom of the pocket, and at the entrance to the transport path there is a flashing mechanism comprising at least one advance surface and at least one delay element located on the side of the transport path, facing the rear wall of the pocket, while the specified at least one advancing surface is placed in the bottom of the pocket with the possibility of movement in the direction from the front wall to the rear wall of the pocket and made to protrude from the bottom of the pocket along the entire length of the bottom from the front wall to the rear wall, while the back wall of the pocket passes below the location of the edge of the banknote when it leaves the gap between the blades of the stacking wheel, and is configured to ensure that when falling under its own weight of a single banknote that came out of the gap between the blades of a rotating wheel for stacking banknotes, this banknote touched the advancement surface in the position in which its edge was facing the entrance to the folding mechanism ism, and the front wall is made with the ability to provide a slope of the specified banknote, necessary for the advancement of banknotes by the folding mechanism into the transport path.

In the claimed invention, the banknotes are coalesced with a folding mechanism and are transferred to the storage device for received money through the transport path. Therefore, the transport path for sheet transport should have a width only slightly exceeding the thickness of the banknote. Unlike the prototype, this requires a small width of the hole in the drive for received money, equal to one or several millimeters. Thus, leaf transfer of banknotes to the bank for received money allows you to pair this bank with a temporary bank more secure. Security is increased, since the small width of the transportation path and, correspondingly, the holes for its passage make it difficult for criminal money to enter the drive.

When the bundle is accumulated in the pocket, the first banknote is tilted, leaning on the advancing surface and on the front wall of the pocket so that its lower edge is near the entrance to the folding mechanism. In fact, it covers the entire bottom with the advancing surface, and is pressed to this surface under its own weight. The banknotes following it lay in a bundle on the first banknote. The edges of the banknotes in the stack are facing the front and back walls, in contrast to the prototype, in which the edges are facing the bottom of the pocket. The weight of the banknotes in the stack is applied to the first banknote and additionally presses its surface against the advancement surface, thereby increasing the friction force between these surfaces. When the folding mechanism begins to move, the first banknote is fed into the transport path. The advancing surface in contact with it, due to the frictional force, advances the banknote to the entrance to the transport path, and the stopping element prevents several banknotes from entering the transport path with it. Banknotes lying in a bundle on the first banknote are fed in order to the transportation path after it. Thus, due to the orientation of the banknotes in the pocket, the force of gravity ensures the creation of friction between the promoting surface and the single banknote, or the lowest banknote in the bundle, which ensures reliable lamination.

A case is possible when the bundle is formed incorrectly and some banknote partially went beyond its limits, or the banknote from the very beginning turned out to be outside the bundle due to improper stacking. As the pocket is emptied, the banknote, under the action of gravity, will lower toward the bottom until it touches the advancement surfaces, since these surfaces protrude from the bottom all the way from the front wall of the pocket to the back. The movement of the advancing surfaces will carry the banknote to the folding mechanism and it will be fed into the transport path. It can be concluded that the configuration of the pocket elements ensures that the banknote does not have the opportunity to avoid contact with the advancing surface and pulling it into the transport path. Thus, unlike the prototype, the claimed invention provides the movement of banknotes in the drive for the received money, even in the case when the banknote entered the bundle only partially or lay on top of the bundle.

The claimed invention does not limit the choice of technical implementation of the sheathing mechanism. Any suitable type of capping mechanism may be used, a non-exhaustive list of examples of which has been given above in this description. However, the folding mechanism must be oriented in relation to the first banknote so that the folding of the banknote is possible. Therefore, the configuration of the front wall should provide the inclination of this banknote, necessary for feeding the banknote with a folding mechanism into the transport path. For each type of folding mechanism, there is a certain range of allowable banknote tilt angles, the edge of which is at the entrance to the folding mechanism, in which this mechanism ensures reliable feeding of the banknote into the transport path. We are talking here about how to submit a single banknote, and the filing of a banknote, on top of which lies a bundle of other banknotes. If the angle of inclination is out of the acceptable range, feeding the banknote becomes unreliable or impossible. Accurate calculation of this angle is a rather complicated task and, as a rule, requires computer simulation. However, in practice it is easy to verify whether a certain angle of inclination of banknotes is acceptable for a certain type of coater. If the banknote, the edge of which is located at the entrance to the leafing mechanism, is located at a certain angle of inclination and at the same time reliably coalesces with any allowable number of banknotes lying in the bundle on it, then this angle is valid for this mechanism. Reliable peeling refers to the feeding of banknotes into the transport path without jamming and without a significant decrease in real productivity in relation to the estimated performance of the coater. For definiteness, we can arbitrarily assume that a decrease in the productivity of lamination in relation to the calculated value of less than 50% is acceptable.

Slotting mechanisms, as a rule, are used in banknote processing machines to solve the problem of feeding banknotes strictly on one sheet. For example, when banknotes from a bundle are fed to the sensor unit for authentication, it is not allowed to supply double banknotes or several banknotes moving with partial overlap (in the form of a chain). In addition, as a rule, significant distortions of banknotes exceeding 7-10 degrees are not allowed. Therefore, in normal practice, slicking mechanisms require careful tuning and are sources of a number of machine operation errors, such as a twin error, a chain feed error, or a skew error. However, in the claimed invention, the supply of double banknotes, the supply of banknotes with overlapping, as well as a significant distortion of the banknote do not interfere with the operation of the transport route and are quite acceptable. Therefore, the stringing mechanism does not have such stringent requirements, and it can rarely cause any failure in the transportation of banknotes. That is, the use of the slitting mechanism does not lead to a decrease in the reliability of the transfer of banknotes from the temporary storage to the storage for received money. On the other hand, the use of gravitational pressing of the banknote to the promoting surface, and the location of such a surface or surfaces all the way from the front wall of the pocket to the back, increase the reliability of the transfer of banknotes.

As the promoting surface, both the outer surface of the wheel mounted rotatably on an axis placed longitudinally along the bottom of the pocket and the surface of the belt mounted with the possibility of longitudinal movement can be applied.

The advancement surface on the wheel can be made of elastomeric material and equipped with notches. This provides increased frictional force between the advancing surface and the banknote, which improves the operation of the caking mechanism.

In one possible implementation, a restraining element is used made of an elastomeric material and separated by a gap from the advancement surface. The use of an elastomeric material makes it possible to obtain a sufficiently large friction force, such that it exceeds the friction force between sheets of paper passing through the aforementioned gap. The resulting ratio of the friction forces allows you to separate the attached sheets of paper and prevent them from going into the transportation path. It is known that the coefficient of friction of an elastomeric material can be controlled over a wide range by changing the formulation. In particular, it is possible to select the coefficient of friction necessary for the correct operation of the sizing mechanism, in which the friction force between the moving surfaces and the banknote will be higher than the friction force between the holding elements and the banknote. Criteria for selecting characteristics of elastomeric materials for parts of the sheeting mechanism are well known to specialists in the design of banknote processing machines.

To improve the operation of the separation mechanism, an additional fixed stop surface made of smooth metal and placed in the immediate vicinity of the retaining element can be introduced into this mechanism, so as to ensure that it is touched by a banknote in the gap. An additional fixed stop surface assumes part of the force, which in its absence, the surface of the banknote applies to the restraining element. A smooth metal surface has a small coefficient of friction, which is significantly less than the coefficient of friction of the elastomeric material. Due to this, with the introduction of an additional fixed fixed surface, the total frictional retarding force acting on the banknote is reduced. Thus, it is possible to control the friction force over a wider range than is possible by changing the formulation of the elastomeric material.

Several propelling wheels located on a common propelling shaft may be used. This provides a more reliable movement of the banknote due to the application of advancing efforts at many points along the entire width of the banknote.

Additional propelling wheels may be added to this design, placed on an additional shaft that is connected by transmission to the propelling shaft. The use of advance wheels placed on several shafts allows the advance surfaces to protrude from the bottom of the pocket along the entire length of the bottom from the front wall to the rear wall, and if necessary, increase the length of the bottom.

In some implementations of the invention, it is further envisaged that the advancement surface may move in a direction from the rear wall to the front. Movement in this direction can be used for two purposes. Firstly, when a packet of several banknotes becomes jammed in the folding mechanism, the advancement surface can be returned a short distance back to eliminate jamming, after which the attempt to move the banknotes into the bank for received money can be repeated. Jamming a bag of several banknotes is a very rare event and is usually associated with excessive wear or damage to a banknote. Secondly, moving the moving surface backward by the length of the bottom transfers the stack of banknotes from an inclined position to a vertical one. At the same time, the edges of banknotes, previously aligned on the back wall, are installed on the advancement surface, and the lowest banknote in the bundle rests against the front wall with its surface. This situation, in the case of the return of banknotes, creates a convenience for the user to remove the bundle from the pocket.

The advantages of a temporary storage device according to the claimed invention are realized in a system for receiving banknotes, comprising an input pocket for receiving banknotes from a user in the form of a bundle, a reject pocket for returning rejected banknotes to a user, a banknote validator, a temporary banknote store made in the manner described above and configured to arrange banknotes in the form of a bundle, and containing a door designed to prevent user access to the bundle of banknotes located in the temporary storage, banknote path, providing movement of banknotes from the input pocket to the validator, from the validator to the reject pocket, and from the validator to the temporary storage device, as well as a storage device for received banknotes, and a transportation path for moving banknotes from the temporary storage device to the storage device for received banknotes, and the storage device for Received banknotes contains a removable cartridge made with the possibility of sheet laying of banknotes in the foot.

The removable performance of the cartridge in the drive for received money is necessary for the implementation of unloading the system from the money accepted by it using the generally accepted collection technology. In this conventional technology, collectors remove a cassette of money from a machine for receiving banknotes and deliver it to a cash settlement center, and instead of it, an empty cassette is installed in the machine. In the cash settlement center, banknotes are removed from the cassette and counted. The generally accepted collection technology implies the lack of direct access of collectors to banknotes.

The use of a slitting mechanism provides a sheet-fed supply of banknotes to the transport path, which makes it possible to pair a temporary storage device made according to the claimed invention with a storage device for received money, which uses forced sheet formation of the foot. Note that the prototype uses a drive for received money, working on the principle of free fall, and does not allow the use of a drive with a sheet stacking banknotes in the stack. Through the use of a drive with forced sheet formation of the foot, a higher banknote density can be achieved and the size of the entire banknote reception machine can be reduced. In addition, when unloading the contents of a drive for received money, randomly lying banknotes in a gravitational drive require significantly more labor costs from the cash settlement center staff than banknotes folded in a pile. The advantages indicated here, that is, the increased density of the stacking of banknotes and the convenience of maintaining the drive for received money, are the technical result of the system according to the claimed invention. Along with this, the system implements all of the above technical results inherent in the temporary drive according to the claimed invention.

In FIG. Figure 9 shows an implementation of a temporary drive with forwarding wheels located on an additional shaft.

In FIG. 10 shows the pairing of a temporary storage device with a storage device for received money, in which forced formation of the foot is applied.

As shown in FIG. 1, the temporary storage device includes an input port 1, a stacking wheel 2 with curved blades, a fixed banknote ejector 3, a front wall 4 of the pocket made of polished stainless steel, and a bottom 5 of the pocket. The input port 1 is a slit-like hole through which banknotes are fed into the drive from the banknote path, at a certain speed and in a certain direction. From the bottom 5, the advancement surface of the advancement wheel 6 located on the advancement shaft 7 extends in the direction of the width of the pocket. The device uses several identical wheels 6 placed at regular intervals on the advance shaft 7 along the width of the pocket (not shown in the figure). The outer surface of the wheel 6 has a notch and is made of soft rubber having a very high coefficient of friction on paper. It is preferable to use special grades of rubber having a coefficient of friction on paper of approximately equal to one.

The pocket is also limited by the rear wall 8, on which a stop element 9 made of hard rubber with a lower coefficient of friction is placed, and a fixed abutment surface 10 made of polished stainless steel. The retaining element 9 is separated from the wheel 6 by a narrow gap, and a recess is made in the place of closest proximity to the wheel in the delaying element. In more detail, the configuration of the linking mechanism formed by the rear wall 8, the retaining element 9 and the fixed abutment surface 10 and the wheel 6 is shown in FIG. 6. The wedge-shaped free space between the advancing surface of the wheel 6 and the thrust surface 10 form the entrance to the laminating mechanism. The rear wall 8 and the continuation of the bottom of the pocket 5 form a transport path 11 leading from the sheeter mechanism to the entrance to the accumulator 12 for received banknotes.

From the front wall, access to the pocket is closed by a movable door 18, which can be moved from the upper position to the lower to allow access. On top of the pocket is closed from user access by a fixed wall 19.

The banknote path of the banknote receiving machine feeds banknotes 13 to the temporary storage device through the input port 1 (the feeding direction is shown by an arrow). The laying wheel 2 is rotated (the direction is indicated by the arrow). The rotation speed of the stacking wheel 2, the speed of movement of the banknotes 13 at the entrance to the input port 1, and their feed frequency are mutually agreed so that in the gap between each pair of blades of the stacking wheel 2 passing by the input port 1, one banknote from the banknote path . When the wheel 2 rotates, several banknotes 14, previously included in the gaps between the specified blades, are held between its blades. The held banknotes 14 are moved in the direction of the rear wall 8. Their edges abut against the ejector 3, so that the held banknotes 14 are gradually pushed out of the gap between the vanes of the stacking wheel 2. At point 15, located near the interface between the ejector 3 and the rear wall 8, the banknote indicated by pos. 16 (hereinafter, the pushed out banknote), is completely ejected from the stacking wheel and begins to fall freely under its own weight (the direction is indicated by the arrow).

The held banknotes 14, as they move, by the time they are completely ejected from the stacking wheel 2, occupy an inclined position, which is maintained at the popped out banknote 16 and immediately after ejection. Under the influence of air resistance, acting during falling on the lower surface of the ejected banknote 16, the lower edge of this banknote is pressed against a fixed thrust surface 10.

The supporting banknote 17 was fed into the drive first and earlier lowered to touch with the advancement surface of the wheel 6, and its lower edge stopped at the entrance to the flailing mechanism. The upper part of the support banknote 17 rests on the front wall 4, so that the height of the front wall 4 defines the angle of inclination of the support banknote 17. The configuration of the front wall 4 is selected so that the touch point of the support banknote 17 and the front wall 4 is near the edge of the support banknote 17, therefore, the weight of the banknote is distributed approximately equally between the wheel 6 and the front wall 4.

As shown in FIG. 2, when the banknotes are further fed into the banknote collector 12, they continue to exit the stacking wheel 2 and fall down along the back wall 8, similarly to the popped banknote 16. In this case, they form a bundle 20, at the base of which is a supporting banknote 17. Pack 20 maintains the same tilt angle that was at the supporting banknote 17 at the time of completion of the fall. The lower edges of the banknotes in the bundle 20 are aligned with a fixed thrust surface 10.

Upon completion of banknote feeding, as shown in FIG. 3, all banknotes from the stacking wheel 2 are stacked in the stack 20, and the stacking wheel drive 2 is turned off. At this point, the machine, in accordance with the maintenance scenario, may enable the user to pick up a stack of 20 banknotes from his pocket. To do this, she lowers the door 18 (the door drive is not shown in the figure).

If the user confirms to the machine the need to transfer the bundle 20 to the accumulator 12 for the received money, the door 18 remains closed, and the process of transferring banknotes from the bundle 20 to this accumulator 12 begins (see Fig. 4). The machine includes a shaft drive 7 (not shown in the figure) for counterclockwise rotation. The lower supporting banknote 17 in the bundle 20, under the action of the frictional force between its surface and the surface of the wheel 6, is carried away in the direction of the stationary abutment surface 10. The lower edge of the supporting banknote 17 abuts against the stationary abutment surface 10 and bends down. With further movement of the supporting banknote 17, this edge enters the gap between the wheel 6 and the retaining element 9. One and the same pressing force perpendicular to the surface of the supporting banknote 17 acts between the banknote and the wheel 6, as well as the banknote and the holding element 9. This force generates friction forces in pairs “supporting banknote 17 -wheel 6” and “supporting banknote 17 - restraining element 9”, proportional to the corresponding coefficients of friction. The material of the wheel 6 has a higher coefficient of friction than the material of the stopping element 9, therefore, the advancing friction force from the side of the wheel 6 is greater than the restraining force of friction from the side of the element 9. As a result of this correlation of forces, the support banknote 17 advances towards the transport path 11 and is output to the accumulator 12 for received banknotes.

The attached banknote 21, lying in the stack next to the supporting banknote 17, is carried along with it to the holding element 9 by the frictional force between the two banknotes. On the surface of this attached banknote 21, located in the gap between the wheel 6 and the retaining element 9, the same pressing force acting along the normal acts. It generates frictional forces in pairs of "supporting banknote 17 - attached banknote 21" and "attached banknote 21 holding element 9", proportional to the corresponding coefficients of friction. In this case, the coefficient of friction of paper on paper is significantly lower than the coefficient of friction of paper on rubber. Therefore, the supporting note 17 cannot further entrain the attached note 21, and this note stops at the entrance to the folding mechanism. However, as soon as the supporting banknote 17 completely leaves the gap in the transport path 11, the attached banknote 21 will come into contact with the wheel 6. After that, the friction force in the pair “attached banknote 21 - wheel 6” will exceed the friction force “attached banknote 21 holding element 9 ", and the attached banknote 21 will move after the supporting banknote 17 in the transport path 11.

Thus, the folding mechanism ensures a continuous supply of banknotes from the bundle 20 to the transport path 11. The drive of the advancing shaft 7 rotates the shaft until the bundle 20 is completely transferred to the transport path 11 and then turns off. The drive is switched off by the signal of the optical sensor of the empty pocket (not shown in the figure).

The mechanism of the flail mechanism is shown in more detail in FIG. 6. In this figure, in stereometric projection, only one wheel is shown for better visualization 6. In fact, as already mentioned, several such wheels are located on the advance shaft 7, and, opposite each wheel, there is a cutout in the stop member 9. Thus, the supporting banknote 17 when passing the gap is deformed by the wheel 6 and partially immersed in the specified cutout. The deformation leads to an increase in the pressing force, and, hence, the friction forces, which determine the movement of the banknote in the gap of the laminating mechanism. This increase in friction forces favorably affects the quality of lamination, as it reduces the parasitic effect of other friction forces acting on the supporting banknote 17 and the attached banknote 21 outside the gap - in the stack 20 and at the point of contact of the supporting banknote 17 and the front wall 4. Note that there is no direct contact between the wheel 6 and the retaining element 9, which explains the low wear of the friction elements of the mechanism and the low power consumption of the drive of the propelling shaft 7.

The fixed abutment surface 10 has a dual function in the leaf mechanism. Firstly, it takes on some of the pressing force when the banknote passes through the gap. Therefore, part of the frictional restraining force is created by friction against the retaining element 9, and part is due to friction on the stationary abutment surface 10. Since the immovable abutment surface 10 is made of polished stainless steel, it has a very small coefficient of friction on paper. Therefore, the distribution of the pressing force leads to a decrease in the friction holding force. This allows, due to changes in the geometric parameters of the retaining element 9 and the fixed thrust surface 10, to establish the optimal ratio between the advancing and retarding frictional forces in the gap of the laminating mechanism.

The second function of the fixed abutment surface 10 is associated with the formation of a bend of the lower edge of the supporting banknote 17. In order to enter the gap of the folding mechanism, the banknote must be bent. In FIG. 5A and 5B, using numbers 24-26, various positions are shown that the support note could take depending on the angle a between the support note and the abutment surface 10. The note 26 is hereinafter referred to as being promoted, since the corresponding angle a, as will be shown below, creates Necessary conditions for advancing to the transportation route.

The advance note 26, under the action of the initial advance friction force from the side of the surface of the wheel 6, abuts against the abutment surface 10. In the initial position 26A, the advance note is not bent. Further, it begins to bend, and due to the deformation of the paper, a force is applied to the edge of the banknote.

Let us consider in more detail the forces arising in this case, as shown in FIG. 5B. The banknote 26 being advanced lies on the rotating wheel 6, so that there is a normal component of the banknote weight P at the point of contact. The coefficient of friction of the banknote on the wheel is K _w , due to which there is an advance force equal to F _a until the banknote edge 26 and the abutment surface 10 touch. _dv = PK _w and directed tangentially (along the banknote). The promoted banknote 26 is acted upon by a force F ₀ , also directed tangentially, which combines additional factors acting on the banknote and not shown in FIG. 5B: a tangential component of the weight of the banknote that is promotional; the friction force on the front wall 4, which inhibits the banknote, and the braking force of friction on the bundle 20 of banknotes lying on top (when the bundle 20 is present). The front wall 4 is made of polished stainless steel having a very low coefficient of friction, and the total weight of the banknote or bundle is distributed approximately equally between the touch points of the wheel 6 and the front wall 4. Therefore, the sum of the forces PK _W + F ₀ is generally promotional, since the friction force between the bill being advanced 26 and the wheel 6 is greater than the friction force against the front wall 4. If the bill stack 20 is on top of the bill being advanced 26, then the braking force of friction is added with bundle banknotes. However, this friction force, nevertheless, is insufficient to block progress, since the coefficient of friction in the "paper - paper" pair is significantly less than the coefficient of friction "promoted banknote 26 - wheel 6". Thus, until the contact of the abutment surface 10, the promoted banknote 26 confidently advances due to the rotation of the wheel 6.

, проекция которой F_rK_scosα на направление банкноты затормаживает ее продвижение. Таким образом, после касания упорной поверхности 10 на банкноту начинают действовать дополнительно возникшая сила F_C, складывающаяся из продвигающих и тормозящих компонентов:After the moment of contact, a reaction F _{r of the} thrust surface occurs, 10 directed normal to this surface. It creates the tangential component F _r sinα acting against the promoting force, and the normal component F _r cosα, bending the banknote from the abutment surface 10. This normal component creates a pair of forces together with P, resulting in an increase in the promoting force: F _{a dv} = (P + F _r cosα) K _w . On the other hand, when touched, the friction force of the promoted banknote 26 against the abutment surface 10

, the projection of which F _r K _s cosα on the direction of the banknote inhibits its progress. Thus, after touching the thrust surface 10 on the banknote, the additional force F _C starting from the moving and braking components begins to act:

F _C = F _r cosαK _w -F _r K _s cosα-F _r sinα = F _r ((K _w -K _s ) cosα-sinα)

This force can, on the whole, be both advancing and inhibiting, and is proportional to the reaction of the abutment surface 10. It is advancing at angles α <α ₀ , where tgα ₀ = (K _w -K _s ). When there is still a bundle of many banknotes 20 on top of the promoted banknote 26, the promoting force, generally proportional to the weight of the bundle, is very large in comparison with F _C and ensures reliable promotion of the banknote regardless of F _C. Most importantly, the effect of F _C when the promoted banknote 26 does not have a stack of 20 of many banknotes above it.

Thus, in order to increase F _C and thereby improve the advancement of the banknote, it is necessary to reduce the angle between the banknote and the thrust surface 10, and also to ensure a minimum coefficient of friction K _s between the banknote and the thrust surface 10. This determines the choice of polished steel as the material for the thrust surface 10. Reducing the angle leads to an increase in the moving component of the force and a decrease in the braking component. Even if F _C is negative, advancement of the banknote is still possible as long as F _C + PK _w + F ₀ > 0 (1), albeit with a decrease in the promoting force. This explains the fact that the banknote can also be promoted with α _MAX ≥α≥α ₀ . When α <α _{0, the} banknote touching the abutment surface 10 leads to an increase in the advancement force along with an increase in the reaction F _{r of the} abutment surface 10.

As you move further from the starting position 26A, the advance note continues to bend at the first position 26B and the second position 26C. In the third position 26D, the edge of the advance note goes into the gap between the wheel 6 and the stop element 9. The excess of the advance force over the delay when the note is in the gap has already been described above. In the subsequent fourth 26E and fifth 26F positions, movement in the gap continues, accompanied by the immersion of the promoted banknote in the cutout, its deformation and an increase in the pressing force. Further, the edge of the promoted banknote 26 goes into the transport path 11, and the banknote continues to move under the influence of mainly advancing forces in the gap. Thus, only if the promoted banknote 26 reaches the gap, it will be picked up by the promoting force in the gap and will be able to enter the transport route.

When a bundle of many other banknotes is on top of the supporting banknote 17, the weight of this bundle, as already mentioned above, determines a sufficiently large amount of the initial promoting force. As a rule, it is enough to bend the banknote even with a large angle between the banknote and the abutment surface 10, and bring the banknote to the gap. The angle is most important for the case of a single supporting banknote 17, the initial promoting force of which is small, since this force arises only because of the own weight of the banknote. If the angle between the supporting banknote 17 and the abutting surface 10 is such that when the banknote 17 abuts against the abutting surface 10, the braking force component exceeds the propelling force, then the banknote may not bend to the right extent and may not reach the gap.

Consider the possible options for the undesirable location of the supporting banknote, in which sustainable progress cannot be guaranteed. The first undesired banknote 24 and the second undesirable banknote 25 differ from the promoted banknote 26 by the angle α. For undesired banknotes 24 and 25 in FIG. 5, due to the large angle α, the condition F _C <0 is satisfied, that is, F _C has an inhibitory effect. The first undesirable banknote 24 is directed to the surface 10 at such a large angle that it can hardly bend, and immediately stops. The second undesirable banknote 25 forms a slightly smaller angle with the surface 10 and forms a slight bend at position 25B. However, in an attempt to further advance, the braking force F _C increases with the reaction F _r and completely compensates for the promoting force PK _w + F ₀ acting on the banknote until it touches the abutment surface 10, so that the second undesirable banknote 25 stops. Only the advance bill 26, forming the maximum allowable angle α _MAX , can reach the clearance in position 26D. At angles less than α _MAX , the banknote also reaches the gap. The angle α _MAX slightly exceeds α ₀ due to relation (1). In practical experiments, it was found that α ₀ is 35-45 degrees, depending on the type of rubber used on the surface of the wheel 6, and the _MAX is approximately 55 degrees. The slope of the supporting banknote 17, which is determined by the configuration of the front wall 4 of the pocket, must be selected with some additional margin from this value to guarantee advancement of even a single banknote to the gap.

Our calculations are simplified, they do not take into account many factors, such as the stiffness of a banknote during bending. The purpose of these calculations is to show the key relationships that indicate the possibility of advancing the supporting banknote through a folding mechanism. For banknotes with great rigidity, bending near the leading edge causes the opposite edge of a single banknote to rise above the point of contact with the front wall 4, and the weight of the banknote is fully transferred from the back wall to the point of contact with the promoting wheel 6. This is increases the advance force more due to the increase in the frictional force between the wheel 6 and the advance bill 26. In the figure of FIG. 5A shows the possible position of the opposite edge 26G of the promoted banknote 26. This banknote, due to its high stiffness, after the leading edge enters the gap of the folding mechanism, straightens with elastic force and assumes a position close to vertical.

The reasoning given here shows how to select the angle of inclination necessary for feeding banknotes with a folding mechanism into the transport path. The described design of the folding mechanism is simple, does not require precise adjustment and provides reliable tightening of the banknote in the gap between the promoting surface and the retaining element. Possible implementations of the invention are not limited to the described design of the linking mechanism.

In FIG. 7 shows the folding of a single banknote 27, which was not packed in the bundle 20 due to some malfunction of the stacking wheel 2. This could happen, for example, if a single banknote 27 entered the input port 1 with a large skew and was not securely fixed in the gap between the blades of the wheel 2 laying. Such a single banknote 27, until the complete folding of all banknotes of the bundle 20 will remain inside the temporary storage, and shift in the direction of the bottom 5 under the action of gravity. The design of the temporary drive is made in such a way as not to create obstacles to such a lowering. In particular, the front wall 4 and the rear wall 8 are oriented at a large angle to the horizontal, so that the banknote slides along them in the direction of the bottom 5, until it touches, in position 27A, the moving surface of the wheel 6. By touching the moving moving surface, it forces Friction against this surface is carried away in the direction of entry into the laminating mechanism, to position 27B. The configuration of the front wall 4 provides an angle of inclination necessary for supplying banknotes with a flashing mechanism to the transport path 11. The banknote 27 enters the gap of the flail mechanism and then, through the transport path 11, is sent to the bank 12 for received banknotes.

From the above description, it becomes obvious that when designing the internal elements of the temporary storage device, it is necessary to avoid the formation of surface areas for which the banknote could accidentally catch and avoid falling onto the moving surfaces. In addition, it is desirable to ensure the rotation of the stacking wheel 2 during the rotation of the advancement wheel 6, in order to eliminate the already unlikely jam of the banknote in the upper part of the temporary storage.

Empty pockets, as indicated above, are monitored by an optical sensor. If, after turning on the drive of the wheel 6, the emptying does not occur for a long time, then the machine stops working and gives a fault message.

If the user wants to pick up the banknotes from the temporary bank instead of transferring them to the bank 12 for received banknotes, then he needs to take a stack of 20 from the bank with his fingers. Due to the movement of the wheel 6 in the direction opposite to the direction of lamination, it is possible to change the inclined position of the pack 20 to close to vertical, which is more convenient for the user to remove from the temporary storage, as shown in FIG. 8. After the user makes a decision about the need to return banknotes from the temporary drive, the wheel drive 6 is started to rotate in a counterclockwise direction. The lower edges of the banknotes in the bundle 20 sequentially, starting from the lower banknote, come into contact with the ribbed surface of the wheel 6, and advance towards the front wall 4. At the same time, they change orientation and line up parallel to the wall 4 in the form of the returned bundle 28. Wheel 6 slips relative to the edges of the banknotes that have already taken their position in the returned bundle 28. The drive of the wheel 6 is turned off after the surface of the wheel 6 rotates counterclockwise enough to fully form the returned bundle 28. Then, lower the door 18 and enable the user to pick up the returned pack 28.

If it is necessary to enable the accumulation of a bundle with an increased number of banknotes, it is more preferable to use two groups of advance wheels 6 and 6 'located on the advance shaft 7 and the additional shaft 7', as shown in FIG. 9. The groups of wheels 6 and 6 'are overlapped, so that their surfaces completely cover the entire length of the bottom 5 from the front wall 4 to the rear wall 8. The shafts 7 and 7' are connected by a belt drive (not shown in the figure), so that the surfaces of the wheels 6 and 6 'move at the same speed. Covering the entire length of the bottom with 5 advancement surfaces ensures that any banknote in the pocket is advanced before entering the folding mechanism and further into the transport path 11. The wheels 6 and 6 'have a reduced size, which is seen when comparing the configuration of the pockets in FIG. . 1 and FIG. 9. Due to this, the depth of the pocket and the available height of the back wall 8, along which an enlarged bundle 29 is formed, increase. The increased length of the bottom 5 allows you to place on the bottom of the bundle 29 of an increased size in a position close to vertical, which is important for convenient return of banknotes to the user. To put the pack in this position, turn the wheels 6 and 6 'counterclockwise.

In FIG. 10 shows a part of a system for receiving banknotes, consisting of a temporary storage device and a storage device for received money. The figure does not show: an input pocket for receiving banknotes from the user in the form of a bundle, a reject pocket for returning rejected banknotes to the user, a banknote validator, and a banknote path that ensures the movement of banknotes from the input pocket to the validator, from the validator to the reject pocket, and from the validator to temporary storage. These elements have a generally accepted design, well known to specialists and described, for example, in the prototype of the claimed invention.

The transport path 11 leads to the entrance slit 41 in the cassette 40 located in the drive 12 for received money, made in the form of a safe. Immediately behind the slit 41, the banknote 36 leaving the transport path 11 passes between the transport roller 31 pressed to each other and the pressure roller 32. When a bundle of banknotes 20 is transferred from the temporary bank to the bank 12 for received money, a common drive (not shown ) is used to rotate the advancement wheel 6, the transport roller 31, and the stacking wheel 33. The rotation of the transport roller 31 is synchronized with the rotation of the advancement wheel 6, so that the linear velocities of the surfaces of these oles match. The transport roller 31 pushes the banknote 36 into the gap between the petals of the stacking wheel 33 located in the cassette 40. The rotation speed of the wheel 33 is synchronized with the rotation of the wheel 6 and the roller 31 so that during the passage of one banknote between the rollers 32 and 31, the wheel 33 is rotated by an angle slightly exceeding the pitch of the petals of this wheel. Due to this, the placement of one banknote 37-38 in the gap between the petals is provided, moreover, the gap between the petals sometimes remains blank. Banknotes 37 move with the wheel 33 and are stationary relative to this wheel. Banknotes 38, which entered the wheel earlier than banknotes 37, come into contact with the ejector 34.

The stationary ejector 34 provides the ejection of banknotes 38 from the stacking wheel 33 during rotation of the wheel. Banknotes 38 are pushed over the stack of banknotes 39 located on the movable table 35. The paddle wheel blades protects the edges of the banknotes 38 from abutting against the edges of the banknotes in the stack 39. Table 35 has a motorized drive (not shown) that lowers the table 35 and with it the pack 39 as new banknotes 36 are received in the cassette.

When the table 35 reaches the low position, a signal is issued to fill the cassette 40, and the system is temporarily stopped. Then, the cassette 40 is removed by collectors from the safe 12, and instead of it is inserted an identical empty cassette, in which the table 35 is in the initial, highest position. After that, the system is again ready to receive banknotes in the cassette 40. The filled cassette is delivered by the collectors to the cash settlement center, where the banknotes are removed and counted, and the table 35 is raised to its initial position. After that, the empty cartridge 40 can again be installed in the system.

The movement of banknotes into the cassette is controlled by optical sensors (not shown in the figure). These sensors detect jamming of banknotes on the way from the advancement wheel 6 to a pair of rollers 31.32. In the event of a jam, the machine stops accepting banknotes and issues a malfunction message.

It should be noted that the described mechanism of forced stacking in the cassette 40 remains operational if a double bill or a slant banknote comes out through the transport path 11, or when the banknotes come with an overlap. The width of the gap between the petals of the wheel 33 is enough to accommodate, in extreme cases, several banknotes, which solves the problem of dual feed. During the movement of a pair of banknotes with overlapping, in connection with the location of the advancement wheel 6 on the right side (hereinafter the conditional arrangement in Fig. 10 is indicated) of the transport path 11, the lagging banknote in this pair is braked by the delaying element 9, and is on the left side of the transport ways 11. Accordingly, when it passes into the gap between the petals of the stacking wheel 33, it is protected from falling out of the gap between the petals, due to those banknotes 37 that had previously entered the wheel 33 and turned out to be Ava. One way or another, the lagging banknote will be inserted by the rollers 31, 32 into any of the gaps between the petals of the wheel 33. The same applies to the skewed banknote. Therefore, there is no strict requirement for sheet feeding to the operation of the coater, and the supply of double, skewed or overlapping banknotes is allowed without reducing the reliability of stacking.

When designing a sheeting mechanism, there is always a tradeoff between the reliability of sheet separation and the reliability of picking up sheets at the entrance to the mechanism. This compromise is decided by the efficiency of the delay element. For example, increasing the gap between the advancing surface and the retaining element increases the reliability of picking up sheets at the entrance, thereby dramatically reducing the likelihood of idle operation of the coater without picking up sheets. The flip side of this phenomenon is the increased frequency of filing of double, overlapping or skewed banknotes. Usually, a compromise is chosen in the direction of increasing the efficiency of the delaying element in order to reduce the likelihood of double, overlapping or skewed banknotes. However, when implementing the claimed invention, it makes sense to slightly reduce the effectiveness of the delay element in order to guarantee the pickup of all banknotes located in the temporary storage device. The concomitant increase in the number of doubled, overlapping or skewed banknotes, as already indicated, will not lead to a decrease in the reliability of the entire system or device for receiving banknotes.
