EP2441693A1 - Method and device for opening coin rolls - Google Patents

Abstract

The method involves forming a stack from multiple coins (10) of equal measurement. A coin roll (4) is supported on two bearings (2,3), where the force (7) is applied on the coin roll against the bearings. The coin roll is bent in its longitudinal axis. A cover (9) is ruptured by applying shear stress for emptying the coin roll. An independent claim is also included for a device for opening of a coin roll.

Description

The invention relates to a method and apparatus for opening coin rolls, which are formed from a finite number of coins and provided with a sheath made of a material of low tensile strength.

It is known that such coin rolls accept coins of almost the same value in finite quantities. In particular, such coin rolls serve simplified handling, counting, storage and transportation.

However, if such coin rolls are opened, this results in a considerable amount of manual work. The coin rolls, which are usually wrapped in paper, can only be opened by opening the paper wrapper and dislodging the stack of coins. This is a purely manual activity, whereby the executives have to handle significant masses working days, especially in banks, in case of a correspondingly high rate of seizure of coin rolls. This can lead to high labor costs and health problems.

Another problem is that performers usually open the coin rolls on a work surface in the form of a desk or countertop, whereby the coins released from the coin rolls form a heap, which must then be placed in a transport container to ensure further processing of the coins , This also increases the labor costs.

Although it seems possible to empty coin rolls manually in containers standing on the ground. However, the problem arises that individual coins can fall next to the container and subsequently a time-consuming search of these coins is necessary. For the further processing steps, the containers but again be brought into working height of the subsequent machinery and equipment, which leads to increased physical stress or makes corresponding lifting and conveying devices necessary.

After a proposal in DE 198 55 888 A1 the problem should be solved in that the wrapped coin roll is detected at its periphery by a holding device and is subsequently ejected from the packaging casing with a force acting coaxially to the stack.

This method has significant disadvantages. It must be found a balance of power between the holding device, the packaging wrapper and the wrapped coins of the shape that the holding device on the one hand holds only the packaging casing while the stack of coins to move out of the packaging casing. Even minor changes in the friction conditions due to wear, deformed coins, changes in paper texture and the like can cause that no successful emptying of the coin rolls is possible. The most significant disadvantage, however, is that for each diameter of a roll of coins own holding device and under certain circumstances, a separate stamp must be provided. It follows that when changing the diameter of the coin rolls considerable expenses for the conversion of such a device must be made.

An equally effective solution is, for example, also in US 3,781,987 A contain.

In processes which provide for emptying coin rolls by axial thrust, it is a hindrance if there is an impact or a crimp on the cladding on the front side. Therefore, there are a number of proposals to eliminate an impact or flanging on coin rolls in advance. So is in DE 199 48 70 U describes a lever tool with which a flange can be torn open, in order then to be able to manually empty the opened coin roll.

Solutions for cutting with fixed, movable blades or roller blades included DE 81 28 520 U1 and DE 199 01 493 A1 ,

A major disadvantage of these solutions is that the coins contained in the end of the stack can be damaged in the cutting process and also the cutting tools are subject to high wear as soon as they have contact with the coin metal. On the other hand, a coin roll opened at the end is not yet emptied, with some of the solutions anyway providing only a subsequent manual emptying. Thus, the main problem of the complete emptying of the coin rolls is not solved.

Other proposals relate to the cutting of the coin rolls in the longitudinal direction, such as US 4,106,196 A . US 5,964,388 A and US Pat. No. 6,401,339 B1 suggest. In these solutions, there is a risk of damaging all the coins contained in the stack and, moreover, the cutting tools are subject to high wear as soon as they come into contact with the coin metal.

After a proposal in DE 100 80 018 B4 coin stacks are to be given in the longitudinal direction in an opposite pair of profiled rollers and broken up therein. The roll profiles are sharp-edged. With this method, the coins contained in the coin rolls are highly likely to be damaged and therefore this solution is only suitable for purposes in which the coins removed from the coin rolls are subsequently destroyed.

A proposal in DE 200 21 189 U1 provides to bring to opening coin rolls in a drum, which has inside the drum so designated shell breaker elements. The shell breaker elements should always be aligned in the direction of the drum axis. The process for opening the coin rolls introduced into the drum then proceeds in such a way that the shell break-up elements take the intermediate coin rolls with their rotational movement so far upwards that they come to a labile state of equilibrium and fall down. When dropped, the coin rolls should then hit the faces of the shell breaker elements and the dead weight of the coin rolls should lead to break it up. Damage to the coins is not excluded here.

The main problem is to find a balance between drop height and weight of the coin rolls, so that they break up at all. Since coins of different sizes are usually in use and an opening success has to be achieved even with smaller and lighter coin stacks, there is a risk of damage for coins with larger coins. Another disadvantage is the fact that the falling of the coin rolls on the height of fall, position upon impact and position of the shell breaker elements is not predictable and therefore the probability of breaking the coin rolls is significantly reduced. The result is that the corresponding facilities are designed to be large and the residence time of the coin rolls or coins is correspondingly large. As a result, such devices are inapplicable to facilities with less revenue to open coin rolls. Further, the moving and falling coin rolls as well as the coins in the drum produce an unacceptable level of noise.

It is therefore an object of the invention to provide a method and a process exporting device for opening of coin rolls that work reliably, can be performed with little effort on material and costs, take up little space and, moreover, are easy and simple to manufacture and operate ,

This object is achieved by a method for opening coin rolls according to the features of the characterizing part of claim 1 in conjunction with the features of the preamble of this claim. Likewise, the above object is achieved by a device for opening coin rolls according to the characterizing features of claim 9 in conjunction with the features of the preamble of this claim.

Secondary and subordinate claims relate to modifications of the method and the device and do not limit the scope of protection of the reproduced in claims 1 and 9 invention in this respect.

• Münzrolle — ist ein Stapel mit einer endlich begrenzten Anzahl von Münzen mit zumeist gleichem Geldwert, der von einer Umhüllung aus einem Werkstoff geringer Reißfestigkeit umgeben ist und bei dem die Umhüllung den Stapel stabilisiert.
• Umhüllung — ist eine den Münzstapel stabilisierende Hülle aus einem Werkstoff, der eine geringe Reißfestigkeit besitzt. Bevorzugt ist eine Umhüllung mit einem endseitigen Einschlag an beiden Enden. Weiter bevorzugt ist eine Umhüllung aus Papier.

In the following description, the embodiments and the claims, the terms used are used with the following meaning:

• Coin Roll - is a stack with a finite number of coins, mostly of the same monetary value, surrounded by a sheath of low tear strength material and in which the sheath stabilizes the stack.
• Envelope - is a shell that stabilizes the coin stack and is made of a material that has low tear resistance. Preferred is an envelope with an end-side impact at both ends. Further preferred is a wrapping made of paper.

Impact - is a fold at the end, which limits the envelope almost without play.

Support - are one or more points on the circumference of the coin roll on which the coin roll rests or is held.

Radial force - is a force acting radially on a coin roll.

Separation position - is the position at which a roll of coins can be detected by the transport or working organs of a device.

Working Position - is the position or area where one or more radial forces act on the coin roll and destroy the coin roll.

The method according to the invention is based on the fact that the coin rolls to be opened consist of a stack with a finite number of coins and an envelope enveloping this stack and are inherently stable in this combination. Such kind of coin rolls are manageable and especially rollable items.

According to the invention, at least one coin roll is deformed by at least one force acting on the circumference thereof and in interaction with holding means of the shape that the coin roll is subjected to either flexing or shearing, rupturing its wrapping and emptying the burst coin roll.

For this purpose, the coin roll is placed on spaced supports, so that it is cantilevered or fixed in at least one fixing component so that at least one offset force in turn causes the coin roll to burst and this empties.

Thereafter, at least one coin roll is placed on at least two supports, so that it is cantilevered. In the area of the cantilevered lengths one or more rectified forces are then radially applied to the coin roll, whereby the coins move laterally within the stack. This creates between the coins, the stack of coins and the wrapper a state of tension, the enclosure no longer withstand and tear with appropriate magnitude of the forces acting. After the tearing of the wrapper, this is no longer able to get the stack of coins, which is why the individual coins fall out of the envelope by their own weight.

In another embodiment of the invention, the coin roll can also be picked up by at least one fixing component and held after picking. A force acting on the coin roll from any direction leads to its bursting and emptying, after which the fixing component can open again and release the remains of the envelope of the coin roll.

The method according to the invention can be varied in various ways.

In the bottom of the device, a recess may be provided so that the coins fall into a container disposed thereunder.

For example, the coin roll can be moved with the supports on fixed elements that break up the coin rolls, or vice versa, the breaker elements are moved towards the quiescent roll of coins.

Likewise, the direction of the counteracting forces relative to the perpendicular can vary.

Also possible is a form of the method in which both the supports and the force that initiates the coin roll are moved.

It is also possible to deviate the forces acting on the opposition position from the supports, provided that they can still hold the coin rolls securely.

Furthermore, the method can be designed so that the coin roll over its length has several areas in which it undergoes a bending stress by interaction between supports and stamps. It is advantageous that without additional measures in a device coin rolls of different lengths can be broken and in the implementation of the method always at least a portion of the deflection of the coin roll, but preferably at least 2 areas occur.

The multiple arrangement of regions of bending stress in a single coin roll also has the advantage that the bending stress is further displaced into the end regions of the coin roll to be broken. In this way, it is ensured that in the end regions of the wrapper after breaking up still contained coins are removed by the forces introduced and thus takes place a complete emptying of the coin rolls. Further, the bending required to break the coin roll is less, so that the envelope of the broken coin rolls is highly likely to remain integral. As a result, a separation between the remnants of the wrappings and the emptied coins is much easier.

A preferred embodiment of the method provides per se known elements for feeding and separating the coin rolls, wherein the respectively to be broken up coin roll is in a singling position, in which it can be taken over by working organs of a device.

A further embodiment of the method can provide that the separating position is at the same time the working position.

A further preferred embodiment of the method is to separate the last separating position and the working position from each other. In this case, the separated coin roll is conveyed from the singling position to the working position, wherein the used conveying device generally already has two or more supports, while in the working position the breaking up takes place only with the aid of one or more punches.

For example, the transport element can convey the coin roll linearly or along a movement path. The movement can be continuous, circulating or oscillating. The transport element may be arranged in the form of discs or arms on a shaft which carries isolated coin rolls on a circular path to the working position.

It is possible to provide a plurality of separating and / or a plurality of working positions over the circumference of the circular path, whereby the productivity of the method can be increased.

Particularly advantageous is an embodiment of the method in which isolated coin rolls are moved on a circular path and the necessary for the introduction of force punch are stationary. While moving on the circular path, the coin roll approaches the punches and is broken open. With appropriate positioning of the stamp, it is possible to break up coin rolls with different diameters.

The punches can be designed so that their active surface describes an arc shape that steadily approaches the path of the transported coin rolls and finally cuts through them. This ensures that the coin rolls, after they have come into contact with the stamp, can break when the minimum force is reached, thus keeping the burden, in particular of the coins, low becomes. By the appropriate arrangement all sizes of coin stacks can be edited with the same process design at the same time.

The device required for carrying out the method according to the invention is constructed such that it enables the above-described method steps.

It consists at least of a first and a second support, which protrude from a base plate. First and second supports are preferably arranged at a distance such that they can support the usually processed coin rolls approximately in the region of the roll ends.

About midway between two supports can act through the device, a force on the coin roll, so that it is subjected to bending or shear, thereby tearing the envelope of the coin roll and the coin roll ultimately breaks, loses its inherent stability and the coins contained emptying.

It is also possible to move the supports from the ends of the roll of coins towards the center and at the same time to arrange additional punches in the region of the ends in opposition to the supports 2. Thus, the bending area is divided into several smaller bending areas and the breaking up of the coin rolls can be done with less force and less deflection.

First and any further supports can be material-integral part of a base plate.

Both supports can also be arranged on movable bodies, in which case a separation between a separating position for the coin rolls and the working position at which the breaking is provided, is provided.

Depending on the type of device, the supports may be part of a carriage that performs a horizontal linear movement or a movement in 2 axes. The carriage movement can also be vertical with a corresponding structure of the device.

All variants described here can also be designed so that more than two supports are used. In the further description, preferably only a first and a second support is mentioned.

A preferred embodiment provides to arrange first, second and optionally further supports on rotatable parts and to move the recorded coin rolls on a circular path. This makes it possible to realize the drive in a simple manner with a motor. To achieve a certain speed, a transmission can be interposed.

The arrangements described above allow a magazine feeder or other types of machine feeders to be located at the singulation position. It is possible to provide known from the prior art supply, storage and separation solutions.

The forces acting radially on the coin roll are applied in the device according to the invention by one or more punches.

These stamps are like the supports in the field of active parts free of sharp or protruding edges and therefore do not lead to markings on the coin roll or the coins. In addition, the stamp can be made according to the invention of a viscoelastic material or coated with such a material that excludes damage to the coins. The coating material can also reduce friction and thus reduce the energy consumption of the device.

Preferred is an embodiment of the device with a plurality of fixed punches, wherein the coin rolls are moved towards the punches.

A further embodiment of the device provides one or more stationary punches, which have an arcuate contour in the contact region. With this contour, the punches are arranged to cooperate with a conveyor which conveys the coin rolls on a path of travel to the workstation. The arcuate contour of the punch cuts it the trajectory of the coin rolls, resulting in a steadily decreasing gap. This makes it possible to break coin rolls of different diameters in the same device. In this case, only varies the contact area between the circumference of the coin roll and the contour line of the punch.

The use of several stamp brings the advantage that the coin roll breaks not only in two parts by the breakage of the envelope, but by further punch the number of break points is increased. This destroys the wrapper in such a way that the wrapper and coins are largely separated and the coins fall out of the wrapper.

The stamp or stamps can also be arranged to be movable with a suitable design of the device, wherein a linear, circular or a movement on a curved path with the aid of the prior art known drive means is possible.

A further preferred embodiment of the device arises when the separating and the working position are identical. Then, without moving the coin roll, it can be broken open with one or more movable punches, which can also be roll punches, in the singling position of a feeder.

Such type devices, in which the method according to the invention is used, can be constructed with little effort, low costs and without requiring much space. This makes it possible to inexpensively provide small-sized devices that operate with high productivity.

The invention will be explained in more detail below with reference to some embodiments and drawings. Showing:

• Fig. 1 - The basic arrangement for a device for carrying out the method according to the invention.
• Fig. 2 - An embodiment in which separating and working position are spatially separated from each other and a punch is used for breaking, which has an arcuate line of contact.
• Fig. 3 - the same arrangement, the Fig. 2 shows, in a front view with not shown stamp.
• Fig. 4 - A further improved arrangement for carrying out the method according to the invention and for the configuration of a device for carrying out the method.

On a base plate 1, a first 2 and a second support 3 are arranged. On the supports 2 and 3, a coin roll 4 is arranged with their ends 5 and 6. In about the middle of the coin roll 4, a force 7 acts from above on the coin roll 4 a. Exceeds the force 7 a certain amount, forms on the bottom 8 of the coin roll 4 a state of tension, the tensile stress is greater than the tensile strength of the envelope 9 of the coin roll 4. The envelope 9 ruptures on the underside 8 of the coin roll 4, wherein the existing stress state dissolves and at the same time the envelope 9 is largely destroyed. Coins 10 contained in the coin roll 4 are emptied after blasting the envelope 9 due to their own weight.

First 2 and second supports 3 are designed with an edged edge in order to avoid damage to the coins 10 contained in the coin roll 4. The same applies to the force 7 in the coin roll 4 introductory stamp.

In the base plate 1, a recess 11 may be arranged below the coin roll 4 through which the coins fall. These can be collected by an arbitrary container arranged underneath.

The method can be carried out such that the coin rolls 4 are initially conveyed via a feed device 12 to a singling position 13. There removes a transport member 14, with a in Fig. 2 not shown Drive 15 is coupled, the coin roll and transported on a circular path in the working position 16th

In the working position 16, the coin roller 4 comes into contact with a punch 17, which has a curved contour line 18. The arcuate contour line 18 is located so that it intersects the center of movement of the coin rolls 4, which lies on a circular path 19. Thus, the existing gap 20 decreases continuously and the incoming coin roll 4 comes inevitably in contact with the contour line 18 of the punch 17. When forwarding the coin roll 4 is broken by the punch 17 and the coin roll 4 can be emptied.

The transport members 14 are spaced from each other and therefore are able to receive the coin rollers 4 at their ends 5 and 6 and to convey. The feeding device 12 has the task of providing in its separating position 13 in each case the next following coin roll 4 for takeover by the transport members 14.

It is possible to make the provision of the coin rolls 4 by gravity, by separating organs or by associated with the device conveyors. Feeding by hand is of course possible.

A preferred embodiment of the method according to the invention provides, as described above, to position a coin roll 21 on a first 22 and a second support 23 as known. However, the supports 22 and 23 are no longer disposed in the region of the ends 25 and 26 of the coin roll 21, but shifted by an amount toward the center of the coin roll 21.

In opposition to the supports 22 and 23, a first force 24 attacks approximately centrally of the coin roll 21 to this and causes a deflection of the same. A second 27 and a third force 28 additionally act in the region of the ends of the coin roll 21, the coin roll being bent twice. It is also possible to provide even more bends over shorter distances.

The second 27 and the third force 28 engage in the region of the ends 25 and 26 of the coin roll 21 to the same, so that there a greater deflection or a greater displacement of the coins can be achieved in the coin roll 21. This makes it possible to ensure a tearing of the envelope of the coin roll 21 into the end regions and in this way to achieve a complete emptying of all contained coins.

In this embodiment of the method and the device, the tearing of the coin roll is already achieved with smaller deflections in terms of amount and thus limits the destruction of the envelope in such a way that it remains predominantly integral and yet all coins contained in the coin roll 21 are emptied.

The first 22 and the second support 23 are designed so that they are truncated in their contact areas 29 and 30, to avoid mechanical damage to the coins.

In the same way, this applies to the contact areas 31, 32 and 33 of FIG Fig. 4 not shown elements that transmit the forces required for the deflections on the coin roll 21.

The invention thus has the advantage that it makes it possible to break up the casings of coin rolls quickly and easily and thus to make the construction of simple, highly efficient and cost-effective devices for carrying out the method possible.
