 Processing of circular workpieces, coins or the like.

description

The invention relates to a device for processing round-shaped workpieces, in particular for canceling coins, according to the preamble of claim 1. Furthermore, the invention relates to a method and a device for unrolling round-shaped workpieces packed in rolls according to the preamble of claims 25 and 28, a device for unpacking circular-shaped workpieces according to the preamble of claim 42 and systems for unpacking and devaluing circular-shaped workpieces according to the preamble of claims 50 and 51, respectively.

The processing of circular-shaped workpieces is of particular importance in the production of coins or other means of payment in the form of hard cash, whereby circular-shaped workpieces in the sense of this application are used both in the actual production in the form of coin blanks and after the minting process up to the delivery of the finished coins as well as the money-emitting institutions may take back damaged or otherwise debited coins. In general, especially when exchanging coin systems, which may become necessary due to decisions of a political or technical nature, a very large amount in the amount of thousands of tons of coins intended for circulation may have to be withdrawn from the market and thus be devalued . In the context of this application, circular-shaped workpieces are to be understood as both unprinted coin blanks and embossed and possibly damaged pieces of money, and this can also be understood to mean medals of any kind and badges or the like.

In the context of the production and redemption of coins, the fact is, in addition to the intended use of proper coins important that, on the one hand, damaged pieces of money that are no longer suitable for circulation are devalued and therefore no longer have to be made marketable in the sense of a means of payment. In addition to this pure devaluation, the devalued coins should be able to be returned to the material cycle after the devaluation, without having to make it impossible for the coins to be put back on the market by unauthorized security measures. A devaluation may also be necessary, for example, for coin blanks that have not yet been minted and which should not be used for minting due to material properties or the like that have not been fulfilled, but which could offer a point of attack for possible improper use if the material is returned unprotected.

A direct return to the material cycle could take place through an immediate melting of such debased or still valuable disc-shaped workpieces. However, it is not always guaranteed, in particular in the case of larger quantities of coins to be melted down, that the optimum melting capacities are always available at short notice for certain coin alloys. Therefore, larger quantities of coins in particular can only be melted in successively, which means that the problem of storing coins that have not yet been canceled remains.

Another possibility, which is already used occasionally in practice, is to devalue coins or other round-shaped workpieces that are to be devalued by passing them under roller-shaped embossing dies in one pass, the roller-shaped embossing dies, for example, groove-shaped impressions in at least one Insert the surface of the coins to be devalued and thereby withdraw the treated coins from being used as a means of payment. Such embossing rollers have previously been used sporadically by minting institutions in order to devalue the coins withdrawn from the money supply due to minor damage. A disadvantage of these known minting devices is that a reliable devaluation of the coins is not guaranteed, since the minting generally leaves only relatively small impression depths in the treated coins and, when more than one layer of coins passes through one another through such a minting device, a reliable all-round devaluation not every single coin is guaranteed. In addition to the low capacity of such systems, the loads on the embossing tools are very high due to the high surface pressures to be achieved in order to achieve sufficient embossing depths, which means that in addition to the relatively short service life of these embossing devices, problem-free capacity expansion is not possible.

Due to the constantly increasing capacity requirements for the devaluation of coins, especially due to the upcoming changeover from eleven national currencies to the euro and the resulting large quantities of old coins, such a project cannot be carried out with the known devaluation devices. Even the problem of the safe storage of old coins withdrawn from circulation up to their gradual devaluation cannot be guaranteed with the known devices.

It is therefore an object of the present invention to provide devices, methods and systems for the various necessary processing stages of circular-shaped workpieces, in particular coins, medals, badges or the like, which, in addition to having a large processing capacity, ensure reliable processing of a wide variety of circular-shaped workpieces in the sense of devaluation enable, in addition to a high level of operational reliability of such systems, a user-friendly and cost-effective system concept for the various machining processes is to be realized.

The object of the invention is achieved with respect to a device for processing circular-shaped workpieces, in particular for devaluing coins, from the characterizing features of claim 1 in cooperation with the features of the associated preamble.

The invention relates to a device for processing round-shaped workpieces, in particular for canceling coins according to claim 1, from at least one processing device provided with profiling, which can be brought into contact for processing round-shaped workpieces under pressure with at least one surface of each round-shaped workpiece. Such a device is further developed in the manner according to the invention in that Processing device are provided at least two profiled rollers, which are rotatably arranged with respect to one another and opposite one another with the setting of a gap which essentially forms a gap, the rotary movement of the rollers being coupled to one another and the disc-shaped workpieces to be machined forming the gap which essentially forms a gap between the rollers pass through and change in the shape and / or dimensions of the interacting profiles of the rollers. In this case, unlike in the case of embossing rollers of known machining devices which have only flat grooves, at least two rollers which are opposite one another and form a gap are profiled in such a way and their rotational movement is coupled to one another in such a way that the cooperating profiles of the rollers have the circular-shaped workpieces in their Change shape and / or their dimensions. The profiling of the rolls allows the essentially gap-forming distance between the rolls to be designed such that the circular-shaped workpieces not only have superficial flat impressions after passing through the gap, but are also changed in their shape and / or their dimensions, that even an approximate restoration of the original shape, which would be a prerequisite for a new re-circulation, for example for coins, is no longer possible. As a result, generally round-shaped workpieces, but in particular also minted coins, can be safely canceled, which means that the canceled coins can be fed back into the material cycle via normal recycling routes without any problem and without special security measures.

In a first embodiment, the profiling of the rollers of the device can be designed in such a way that the original surface and / or the embossing on the two flat sides of the circular-shaped workpieces which have passed through the gap has been completely or substantially destroyed. This can ensure that even with otherwise insignificant dimensional or shape changes, for example, minted coins can be recognized as devalued at first glance, with the choice of the profiling causing the surfaces of the flat sides of such circular-shaped workpieces to be destroyed to a greater or lesser extent can be. A further embodiment provides that the profiling of the rollers is designed such that the circular-shaped workpieces are changed by local deformations in such a way that the dimensions of the circular-shaped workpieces which have passed through the gap are larger perpendicular to their original flat sides than those of the undeformed circular-shaped workpieces . Such a deformation in the form of a thickening of, for example, devalued coins aims primarily at coins that are devalued in this way no longer being capable of being vending machines and can only be replaned by straightening processes by causing large changes in shape, in particular changes in diameter. However, such a change in shape would be reliably recognized in automatic machines and would inevitably lead to the sorting out of such manipulated coins. The local deformations introduced into the round-shaped workpieces to be devalued for this purpose can be caused, for example, by bending areas of the round-shaped workpiece, local compressions or flow processes are also conceivable, which, moreover, can also change, for example, the electrical conductivity of the materials of the coins in such a way that a there is a further selection criterion for illegally returned canceled coins in machines or the like.

A further embodiment provides that the profiling of the rollers is designed in such a way that the edges of the round-shaped workpieces which have passed through the gap are changed compared to those of the unformed round-shaped workpieces. This can in particular contribute to the fact that the round-shaped workpieces are deformed locally or unevenly in certain directions due to the passage through the gap between the rollers, this being able to be achieved, for example, by strong local deformations or different throughput speeds in partial areas of a round-shaped workpiece or different gap widths . As a result, the outer shape of such circular-shaped workpieces can be changed so that such workpieces can no longer be returned to the cash cycle.

It is particularly advantageous that the circular-shaped workpieces are approximately perpendicular to the axes of rotation of the rollers through the gap which essentially forms

Distance between the rollers. In this way, order of the profiles of the rollers substantially transversely to the direction of the circular disc-shaped workpieces are ensured that the profiles of the rollers not only carry out a shape-changing or dimensionally changing processing of the circular-shaped workpieces, but also that the profiles for the transport of the disc-shaped workpieces take care of the gap between the rollers themselves and do not allow the circular-shaped workpieces to slip, as can occur in the known embossing devices.

In a particularly advantageous embodiment, the profiles of the rollers are arranged so that they interlock in the area of the gap, which essentially forms a gap, such that walls defined by the profiles for zigzagging are formed between the rollers for the passage of the circular workpieces. This zigzag arrangement of the walls predetermined by the profiling of the rollers now leads to a likewise zigzag change, in particular the thickness of the round workpieces, as a result of which these approximately zigzag bends can cause a particularly large change in the thickness of the round workpieces.

In a further embodiment, the rollers can have approximately groove-shaped profiles that extend longitudinally parallel to their central axis and remind of teeth of gear wheels. Profiles of this type are simple to introduce into the rollers and, by changing the angular spacing and the groove depth of the profiles, can produce almost any changes in the circular-shaped workpieces to be machined, which in particular also cause strong changes in thickness.

In another embodiment, the rollers can have approximately groove-shaped profiles which are inclined longitudinally to their central axis and resemble teeth of helical teeth or the like gear wheels. Profiles of this type, which have profile shapes which mesh in a manner corresponding to inclined gears or gears which are not straight-toothed in some other way, can significantly improve the running behavior of the rollers as they pass through the circular-shaped workpieces.

It is particularly advantageous that the approximately groove-shaped profiles have sharply delimited cross-sectional shapes. This can ensure that also sharply delimited impressions and changes in shape are introduced into the circular-shaped workpieces, the transport of the circular-shaped workpieces through the gap between the rollers also being improved by the higher grip of these sharp-edged profiles.

It is particularly advantageous if the radial angular spacing of the approximately groove-shaped profiles is selected such that one or more impressions of the profiles can be determined on each round-shaped workpiece that has passed through the gap. A finer toothing can, for example, improve the impairment of the surface of the flat sides of the round-shaped workpieces, while coarser profiles, on the other hand, can increase the change in thickness of the round-shaped workpieces after the passage.

It is also conceivable that the approximately grooved profile of the rolls has interruptions arranged in the longitudinal direction, which, for example, press punctiform or small-area depressions into the circular-shaped workpieces. As a result, a differently embossed pattern can be produced on the flat sides of the circular-shaped workpieces not only in the direction of passage of the circular-shaped workpieces, but also perpendicularly thereto. This can also be used, for example, to impress coded information about the arrangement and distribution of such interruptions in the circular-shaped workpieces, which allow a conclusion to be drawn about the device used or its operator. This can make it easier to identify possible weaknesses in the safety concept if round-shaped workpieces machined in this way should come back into circulation in violation of the intended purpose.

The assignment of the profiles of the rollers is advantageously achieved in that a mechanical gear mechanically couples the two rollers to one another and thus always ensures a uniformly intermeshing interaction of the spaced profiles as the round-shaped workpieces pass through.

It is particularly advantageous that the distance between the rollers, which essentially forms a gap, at least in regions has the same or less ren distance based on the original thickness dimension of the circular-shaped workpieces. As a result, in addition to pure bending or other shaping operations on the round-shaped workpieces, embossing can also take place at the same time if the distance between two interacting surfaces of the rollers is less than the original thickness of the round-shaped workpieces. In this context, it is a further advantage that the width of the essentially gap-forming distance between the rollers can be adjusted. As a result, the gap width can be adapted to different coin types and coin dimensions, which can be, for example, at a distance between 0.6 mm and 5 mm or even more, depending on the currency used. This gap-forming distance between the rollers can advantageously be adjusted by means of an adjusting gear, preferably a wedge thrust gear, which acts on the bearings of at least one roller and displaces them relative to the other roller. It goes without saying that any other relative position of the rolls which is familiar to the person skilled in the art is also encompassed by the invention. In particular for checking the reliability of the devaluation of coins, it is advantageous that the setting of the size of the essentially gap-forming distance between the rollers can be checked, read and, if necessary, logged, so that each type of coin to be validated, for example, is guaranteed that the distance between the rollers that is really necessary for 100 percent validation is guaranteed during the entire processing. This avoids the setting of too large gaps between the rollers due to unauthorized manipulation, which can cause the coins to slip and are not sufficient for the coins to be processed to be safely canceled.

It is particularly advantageous if at least one roller can be deflected elastically against the other roller and can be displaced relative to this roller in such a way that the distance between the rollers increases when the two or more completely or partially overlapping circular workpieces overlap to the common thickness which can adapt to overlapping circular workpieces. This prevents the rollers from being overloaded by overlapping, circular-shaped workpieces entering the gap, since in this case the elastic roller shrinks a little from the fixed roller and thus the roller surface is not overloaded. With appropriate adjustment of the elastic mounting, it is further ensured that the completely or partially overlapping circular-shaped workpieces are pressed together so strongly as they pass through the gap that they combine with one another due to the high deformations and high local deformations, or at least the surfaces of the overlapping coins that do not come into contact with the rollers are also securely leveled or otherwise destroyed. Such an elastic deflection of the rollers with respect to one another can be achieved on the one hand by hydraulic media acting on the adjustment of the elastically mounted roller or also by a mechanical, for example spring-loaded, preloading of the bearing of one of the rollers.

To produce changes in shape of the circular-shaped workpieces passing through the gap, it is advantageous if the essentially gap-forming distance between the rollers at least once reaches a maximum value and a minimum value during the passage of each circular-shaped workpiece and each round-shaped workpiece after passage is lengthened in the direction of flow due to the cyclically changing distance. This results in different degrees of deformation in the direction of passage and transverse to the direction of passage, which leads to an elliptization e.g. leads from previously circular coins. This can be achieved, for example, by a cyclical change in the gap width between the rolls by means of a cyclical lifting movement of at least one of the rolls, and it is also conceivable for the intermeshing profiles of the rolls to be made non-circular in opposite directions.

A particularly good safeguarding of the device against malfunctions by completely or partially overlapping circular-shaped workpieces entering the gap can be achieved if a scraper device, a doctor blade arrangement, a vibratory conveyor or the like is provided between the rollers before the circular-shaped workpieces enter, the one or the feeds the round-shaped workpieces to the rollers only in a single-layer arrangement. Devices of this type for producing a single-layer arrangement are well known to the person skilled in the art and can be designed in many different forms. In addition to the actual devaluation of round-shaped workpieces, it is of particular importance for the processing of large quantities of round-shaped workpieces that the round-shaped workpieces usually packaged in rolls or sacks are brought into a state in which the round-shaped workpieces can be fed to a devaluation device for processing. For example, pieces of money withdrawn from circulation are often counted at the withdrawing institutions and are usually packed in roll-shaped packaging, so that the disc-shaped workpieces on the one hand return packed in roll-shaped paper packaging, which in turn, for example, is packed in bags made of textile materials or plastic bags to bundle the Rolls are packed. It is also conceivable that after counting back the pieces of money they are not packed in rolls and filled directly into such money bags. Due to the large amount of coins or other round-shaped workpieces that are to be returned or to be devalued, the round-shaped workpieces have to be transferred automatically into a condition that can be separated and can be fed to a validation device, since otherwise the personnel costs would be too high for manual unpacking and separation.

It is therefore an object of the present invention to propose devices for unpacking and optionally unrolling round-shaped workpieces, with which large quantities of round-shaped workpieces to be devalued, for example, are automatically transferred from a packaged state to a state which is accessible for validation during a validation.

The object of the invention is achieved with regard to a method and a device for unrolling from the features of claims 25 and 28, with regard to a device for unpacking from the features of claim 42 and with regard to possible systems for packaging and devaluation, the features of claims 50 and 51. The associated subclaims indicate advantageous configurations of the respective devices or systems.

The invention according to claim 25 relates to a method for unrolling round-shaped workpieces packed in rolls. A method of this type is distinguished by the fact that the rolls are placed on a conveyor in an unordered manner. those on which the rollers are aligned with one another and in this arrangement are conveyed to an output point, from which the rollers are placed in a defined orientation in a gap formed between profiled rollers, the rollers being so loaded by the profiles of the rollers when the gap passes through Steady or kinked that the packaging of the rolls breaks open and the circular workpieces emerge from the packaging. According to this method, it is possible, for example, to align emptied rolls from a sack with disc-shaped workpieces on the conveyor so that the rolls are output via a delivery point on the conveyor in a defined orientation in the gap formed between the profiled rollers and by profiling the Rolling the packaging of the rolls, which is usually designed as paper packaging, is loaded in a defined manner in such a way that the packaging is torn open or damaged at least in some areas and the round-shaped workpieces can fall out of the now destroyed packaging, for example by the action of gravity, and thus the bundle of the round-shaped workpieces in shape a role is dissolved. The loading of the rollers through the profiling of the rollers can take place in that the profiling is essentially at a gap to one another and the role of the circular-shaped workpieces, which is quite rigid due to the packaging, is bent and bent between adjacent profiling. As a result, the packaging tears open, advantageously when a plurality of profiles on each roll attack when the roll passes through the gap between the rolls and thus cause several locations to destroy the packaging. It is also conceivable for the rollers to rotate at different speeds of rotation, so that the packaging is torn open and also destroyed by different relative speeds of the profiles of the rollers which act on the packaging of the rollers.

In a first embodiment of the method according to the invention, the rollers are aligned with one another and with the rollers in such a way that the rollers extend into the nip with their longitudinal extension approximately perpendicular to the axis of rotation of the roller. To this end, in an advantageous embodiment, the profiles of the rollers can be aligned approximately parallel to the axis of rotation of the roller, so that each roller passes through the gap between the rollers at several points by other interfering profiles of the rollers can be damaged and the disc-shaped workpieces can fall out of the destroyed packaging immediately after passing through the gap.

A further embodiment provides that the rollers with their longitudinal extension enter the gap approximately parallel to the axis of rotation of the rolls, the profiles of the rolls advantageously being arranged radially on the outer circumference of the rolls transversely to the axis of rotation of the rolls. As a result, each roll is simultaneously gripped in several places by adjacent profiles and the packaging is destroyed, as a result of which the circular-shaped workpieces can be omitted simultaneously in several places.

The invention further relates to a device for unrolling disc-shaped workpieces packaged in rolls according to claim 28. Such a device is characterized in that the device has a conveyor device which aligns the rolls to one another and in this arrangement conveys them to an output point, and profiled rollers has, between which a gap is formed, through which the rollers pass and the profiles break up the packaging of the rollers. The interaction of the pre-orientation of the rollers in the conveyor and the defined passage of the rollers through the gap formed between the rollers ensures that the profiles of the rollers act in a defined manner on the packaging of the rollers and destroy them as intended so that the round-shaped ones Workpieces can fall out of this packaging. This ensures that the packaging of the rolls is damaged so that the coins can fall completely out of the packaging and fed to the subsequent processing stations in a separated state by the passage of the gap between the rollers and without significant impairment of the shape and dimensions of the circular-shaped workpieces can be.

It is of great advantage if the delivery point of the conveyor device has a tipping edge facing the rollers, on which the rollers tip over due to the action of gravity into the gap between the rollers after an end position has been exceeded, since this ensures that after the rollers have been aligned to one another the rollers enter the gap between the rollers in a defined position and orientation and thus the profiles of the rollers interact with the packaging of the circular workpieces in a uniform manner in such a way that the packaging is damaged as intended. A further development can provide that between the tipping edge and the nip of the rollers for guiding the rollers, slideways are provided which also feed the rollers tipped over from the tipping edge of the conveyor in a defined orientation to the nip between the rollers when falling. This ensures that, for example, by means of approximately tubular slideways, the rollers reach their intended orientation even when they fall from the conveying device, without the orientation being changed, for example by colliding adjacent rollers, in such a way that the package is not torn open as intended or no longer is sufficiently guaranteed.

In a first embodiment, the device provides that the rollers have profiles reminiscent of toothing, which extend essentially in the longitudinal direction on the outer circumference of the rollers. In a further embodiment, the conveyor device for interacting with the rollers profiled as above can have a vibration conveyor in which channels for receiving and aligning the rollers in lines are formed approximately coaxially with one another, so that the rollers arranged in lines in the longitudinal direction of the vibration conveyor in the Channels are aligned and then conveyed to the tipping edge at which the rollers also enter the gap between the rollers in their longitudinal direction and approximately coaxially with one another.

Another embodiment provides that the profiling of the rollers is arranged essentially transversely to the longitudinal direction of the rollers radially on the outer circumference of the rollers, in a further embodiment the conveying device has a vibration conveyor which aligns the rollers approximately parallel to one another and transversely to the conveying direction, so that the rollers arranged approximately parallel to one another, with their longitudinal extension approximately parallel to the axis of rotation of the rollers, enter the gap between the rollers. As a result, the roles on several Places captured simultaneously by the profiles of the rollers and thus the packaging damaged or torn at several places at the same time.

It is particularly advantageous if the rolls are adjustable relative to one another in such a way that the width of the gap formed between the rolls or the profiles can be adapted to the diameter of the rolls. As a result, both small circular-shaped workpieces and large-diameter circular-shaped workpieces can be processed in the same device within wide limits, in particular if, in a further development, the gap between the rollers can be adjusted continuously by means of an adjustment gear. This significantly increases the flexibility of the device according to the invention.

It is also important that the profiles of the rollers have at most such a profile height that even with the smallest adjustable roller diameter, the profiles of the rollers do not touch each other. In this way it can be ensured that, even in the case of round-shaped workpieces of small diameter, the packaging is torn open reliably without touching the profiles of the adjacent rollers.

The effect of tearing open the packaging of the rolls can be improved in that the rolls rotate at different rotational speeds, so that in addition to the kinking and bending effects, additional effects of the relative speed play a role in opening the packaging.

The invention further comprises a device according to claim 42 for unpacking round-shaped workpieces which are packaged in sack-like packaging made of plastic, linen, paper or the like. Such a device is further developed in that the disc-shaped workpieces can be packed in the sack-like packaging and brought into the tear-open station, which grips the packaging at the opening end of the sack-like packaging and transports it on a conveyor in a hanging state to a slitting device which tears open the sack-like packaging that the round-shaped workpieces fall out of the sack-like packaging. The tearing open of the packaging in the hanging state has the advantage that the slitting device is small Withdrawal of the hanging packaging bag, even with differently shaped packaging bags, is only loaded to the extent that the packaging is torn open safely without load peaks affecting or destroying the slitting device, as is the case with, for example, essentially rigidly arranged packaging containers. Due to the high weight of the circular-shaped workpieces located in the sack-like packaging, a sufficiently high resistance is guaranteed when the packaging is slit open, so that a large-area slitting or large-area tearing of the packaging can take place.

It is of further advantage if the conveyor transports the sack-like packaging after tearing the packaging to a tapping station, in which the sack-like packaging can be completely emptied, for example by vibrations, eccentrically rotating hammers or the like, even if, for example, in folds of the sack-like packaging individual round-shaped workpieces should still be held. Such a tapping station thus ensures a 100% emptying of the sack-like packaging, even if, for example, after the sack-like packaging has been torn open, residual stocks of the round workpieces should remain in the sack-like packaging.

It is a further advantage if, after passing the knocking station, the conveyor transports the sack-like packaging to an output point, where the sack-like packaging can be collected according to type. As a result, the packaging material can be recycled and thus of higher quality.

In one embodiment, two endless chain chains, or the like, which move over a common section of the circulating web and which are in contact with one another, can be provided as conveyors, which, in the region of the common section of their circulating web, hold the sack-like packaging between them and in transport hanging condition. Such a conveyor consisting of two individual chains is constructed in an uncomplicated and trouble-free manner. At the same time, spring tension of the link chains moving in contact with one another can ensure that the contact pressure between the links chains or the like is sufficient for securely holding the sack-like packaging.

In a further embodiment it is provided that the slitting device has a disc or roller equipped with diamond or hard metal, which slashes or tears open the sack-like packaging over a large area. Such a slitting device, which for example can also be arranged in a height-adjustable manner in the Aufre ß station to adapt to different sizes of the sack-like packaging, engages in the material of the sack-like packaging with a multitude of local edges and ensures that the sack-like packaging is securely caught and torn - kung.

It is a further advantage if the conveyor chains e.g. B. can be stopped under sensor control in such a way that the sack-like packages in the slitting device and the tapping station can be processed with sufficient exposure time.

The invention further relates to a system for unpacking and devaluing circular-shaped workpieces according to claim 50, in which the system has a device for unpacking circular-shaped workpieces packed in sack-like packaging, which tears open the sack-like packaging, a device for devaluation subsequently being provided can, in which the circular-shaped workpieces can be changed in their shape and / or their dimensions such that circular-shaped workpieces designed as coins are devalued as a means of payment. As a result, both the tearing open of the packaging of the round-shaped workpieces themselves and the separation and validation can be carried out in one pass, no further manual operations being required in this pass. Merely the sack-like packaging can advantageously be placed on the unpacking station by hand, after which this sack-like packaging or the individual round-shaped workpieces are automatically further processed.

The invention further provides an installation for unpacking and devaluation of round-shaped workpieces according to claim 51, in which the installation unrolls a device for unpacking packaged in sack-like packaging. has summarized disc-shaped workpieces, which tears open the sack-like packaging, furthermore a device for unrolling the disc-shaped workpieces combined into rolls and, downstream, a device for devaluation. As a result, disc-shaped workpieces packed in rolls similar to sacks can be unpacked fully automatically from the sacks and from the rolls and automatically fed to a validation station, without the need for manual operations with the exception of placing the sack-like packaging on the unpacking station.

It is particularly advantageous if the systems according to claims 50 and 51 are transportable in their entirety, for example arranged on a transport trailer or the like, and can be brought to their respective place of use, since then the entire system is to be devalued and closed, for example at the location of the collection unpacking workpieces and there the unpacking and validation can be carried out directly. This avoids extensive transport processes for the round-shaped workpieces, and safety aspects during validation and unpacking are easier to ensure.

Such a mobile system makes it possible for the money-emitting institutions to take advantage of the unpacking and devaluation as a service without large investments and to only incur costs for the devaluation when required.

In the description, the structure and the mode of operation of the devices according to the invention or the system according to the invention are mainly described on the basis of the devaluation of coins, whereby whenever a coin is mentioned, any type of circular workpiece 4 can be expressly meant. In the context of this application, both blank coin blanks and embossed and possibly damaged coins or the like to be understood, medals of any kind and badges or the like can also be understood here.

1 to 4 show the structure and the mode of operation of a validation station according to the invention, which is designated as a whole by the item number 2. Such a validation station 2 consists first of all of a roller arrangement of the rollers 1, 1 ^' , which are arranged in a housing on a platform 13 and in the manner not shown in FIG. 1. The two rollers 1, 1 ^' rotate in opposite directions in the direction of the arrow 1 1, so that coins which have not yet been canceled and entered into a gap 18 between the two rollers 1, 1 ^' are drawn into the gap 18 and after that Pass through the pair of rollers 1, 1 ^' as devalued coins 3 are issued down into a collecting container 10. The rollers 1, 1 ^' are each driven in the direction of rotation 11 in a manner shown in more detail by a drive motor 9, which is also arranged on the platform 13. Above the roller arrangement 1, 1 ^' there is a filling funnel 8 which, in the case of larger quantities, of coins 4 which have not yet been canceled and which have been transported over an inclined conveyor 5, ensures that the coins 4 which have entered the filling funnel 8 are fed into the gap 18 which forms a gap. The feeder 5, which is provided at its lowest point with a feed point 12 for coins 4, overcomes the height distance between the entry point of the coins 4 into the hopper 8 and the floor level, so that any upstream processing of the coins 4 or a manual task the coins 4 on the feed point 12 for the operating personnel is easy and without great physical effort. The inclined conveyor 5, which can be designed in various forms, for example as a bucket elevator, as a conveyor belt with corresponding drivers or the like, transfers the coins 4 conveyed vertically to a horizontal conveyor 6, which then transfers the coins 4 into the filling opening of the filling funnel 8 issues. A scraper 7 is provided in front of the filling opening of the filling funnel 8, which ensures that the coins 4 enter the filling funnel 8 in a single-layer arrangement on the horizontal conveyor 6, which can also be a vibration conveyor or the like, for example. This has the advantage that in the gap 18 forming a gap in almost all cases only exactly one coin 4 or one a series of individual coins 4 occurs and the gap 18 forming a gap for the passage of the respective coins 4 can be set precisely without the gap 18 forming the gap for such a match in the event of partial or complete covering of individual coins 4. other arrangement would be too small. As a result, the result of the cancellation is always such that all coins 4 on both flat sides are safely canceled, moreover the load on the rollers 1, 1 'is always in the design range and the rollers 1, 1 ^' are partially arranged one above the other or overlapping coins are not suddenly charged.

FIG. 2 shows a top view of the drive and the mounting of the rollers 1, 1 ^' . The rollers 1, 1 ^' are rotated by the drive motor 9 via a gear 14 and a chain drive 16 in the directions of rotation 11, a mechanical assignment of the rotational position of the two rollers 1, 1' being realized via a gear transmission 15 arranged on the side. Such an assignment of the rotational positions is necessary due to the profiling arranged on the rollers 1, 1 ^' with profile teeth 21, since these profile teeth 21 do not touch when the rollers 1, 1 ^' are rotated, but they mesh with one another without contact such that a gap is formed Distance 18 between the rollers 1, 1 ^'is maintained. The coins 4, which are only indicated schematically and are still to be devalued, can enter this gap 18, the profile teeth 21 of the rollers 1, 1 ^' deforming and devaluing the coins 4 in a manner which is shown in more detail in relation to FIG. So that the profile teeth 21 always exactly maintain the predetermined distance 18, the rotational orientation of the rollers 1, 1 ^' must be coupled with each other at any moment. This is also possible, for example, by electrically coupling the two rollers 1, 1 ^′ , which can be driven by separate drive motors 9.

The gap 18 forming a gap is adjusted with a setting device 20 (not shown in further detail) which, for example, shifts at least one of the two rollers 1 or 1 ^' relative to the other roller 1 ^' or 1 by means of a wedge thrust gear or the like. This allows the gap 18 forming a gap to be adapted to different dimensions of coins 4 or also different desired deformation states of the devalued coins 3 can be achieved. In order to secure the roller arrangement against overload, in order, for example, to achieve a single-layer arrangement of coins 4 entering the gap 18 forming a gap, which is not set by the scraper 7 or a squeegee device or a vibration conveyor, the adjustable roller 1 is shown in FIG Hydraulic cylinder 17 biased so that it can move against the force of the hydraulic cylinder 17 from its normal position set by the adjusting device 20 in the direction of arrow 57. If, for example, two completely or partially overlapping coins 4 run into the distance 18, the roller 1 can dodge exactly one additional coin thickness in the direction of the arrow 57, as a result of which the bearing of the roller 1 cannot be overloaded. Due to the elastic bias due to the action of the hydraulic cylinder 17, however, a very large contact pressure of the roller 1 against the roller 1 ^{'will continue to be} present, which in this case too will surely or completely overlap with one another in such a way that a two- or multi-layer arrangement of this type is reliably canceled Coins 4 ensures.

The exact functioning of the adjustment of the adjustable roller 1 is shown once again in FIG. 4, in which it can be seen that the roller 1 is held in a slide-like adjusting device 19, the adjustment being able to be carried out, for example, by means of a wedge-push mechanism in the adjusting device 20. This adjusting device 20 shifts the roller 1 in the horizontal direction in the slide-like adjusting device 19, wherein a pressing force against the flexibility 57 is applied by the hydraulic cylinder 17 via an adjusting tappet 27 to the roller 1, which presses the roller 1 against the roller 1 ^' up to that Presses on the value of the distance 18, which is predetermined by the adjusting device 20. The hydraulic cylinder 17 is actuated by a pump 24 via a throttle device 25, a pressure reservoir 23 being additionally provided which, after the throttle device 25 has been closed, is connected as a buffer to the pressure chamber of the hydraulic cylinder 17. If, for example, a multi-layer arrangement of coins 4 occurs at a distance 18, the adjusting plunger 27 can move back against the compressibility of the pressure space in the hydraulic cylinder 17 and the pressure medium in the pressure reservoir 23 without any significant change in the contact pressure of the roller 1 against the roller 1 ^' . A pressure gauge 26 is also provided, which allows the pressing force of the roller 1 against the roller 1 ^' to be adjusted and at the same time permits monitoring whether inadmissible values occur in the hydraulic system, for example due to larger objects which have entered the distance 18.

In Figure 3a is shown in a very schematic representation of how a coin 4 ^'enters formed distance 18 and the profile of teeth 21 of the rolls 1, ^1' in between the rolls 1, 1 is deformed. The profile teeth 21 of the rollers 1, 1 ^' are reminiscent in their shape and in their relative rotational position to each other of a toothing of a pair of gears, the profile shapes of the profile teeth 21, since they do not mesh with each other, can be selected almost arbitrarily. The profile shape of the profile teeth 21 can therefore have very different shapes, which are favorable in terms of deformation technology and, moreover, also allow identification on which station 2, for example, a coin 4 has been canceled. Such a coding of the arrangement of the profile teeth 21 can be helpful, for example, in order to trace coins 3 that have actually been devalued but have nevertheless returned to the money cycle to their devaluation location and thus to determine whether there was an unreliability in the devaluation.

The coin 4 entering from above into the gap 18 forming a gap, which until then has been essentially undeformed according to the outline shape with the item number 4, can be seen, as in FIG. 3, between the profile teeth 21 of the rollers 1, 1 ^' in the range from Bends 22 deformed in such a way that there are local bends and embossing zones which greatly increase the thickness of the coin 3 compared to the initial thickness of the undeformed coin 4. Figuratively speaking, in the embodiment of the profile teeth 21 shown here, the coin 4 is bent or embossed approximately in a zigzag shape and is therefore no longer suitable for automatic use due to the greatly increased thickness. At the same time, local deformations 22 can also ensure that the thickness of the coin 4 is reduced entirely or in certain partial areas of the cross-section by the distance between the intermeshing profile teeth 21 being less than the original thickness of the coin 4. Thus, an in 3b shown separately, devalued coin 3, which is unfolded zigzag, additionally strong in the direction of thickness pressed and thus the material of the coin 4 become thinner. It is understood by the person skilled in the art that a large number of designs of the profile teeth 21 is conceivable and the assignment of the profile teeth 21 forming the respective distance 18 can be varied within wide limits in order to achieve the best possible and task-oriented devaluation of coins 4.

In the description, the structure and the mode of operation of the devices according to the invention or of the systems according to the invention are mainly described on the basis of the devaluation of coins, whereby whenever a coin is mentioned, any type of circular workpiece 4 can be expressly meant. In the context of this application, circular-shaped workpieces 4 are to be understood as meaning both unprinted coin blanks and embossed and possibly damaged coins or the like. Also, medals of any kind and badges or the like can be understood here.

In FIGS. 5a and 5b, a schematic representation of a first embodiment of an unrolling device 128 according to the invention is shown, in which coins 4 packaged into rolls 114 are released from the roll packaging 115 and essentially separated. For this purpose, a number of rollers 114 are fed via a conveyor (not shown further) to a vibration conveyor 119 designed as a vibration table, which, in a generally known manner, sets the rollers 114 in oscillating motion via spring elements 122 and a drive 123 (not shown) a roller pair 116, 116 'explained later. This vibration conveyor 119 has channel-like depressions 127 which are essentially parallel to one another and into which the rollers 114 of the coins 4 lie due to the oscillating movement and thereby come to lie in a line within the depressions 127. In a manner not shown, rollers 114, which cannot insert into the recesses 127 or which want to insert into the recesses 127 at a location that is already occupied, are stripped and realigned.

The rollers 114 with pieces of money 4 inserted into the recesses 127 are caused by the oscillating movement and the micro-throwing movements caused thereby

Directed onto the rollers 116, 116 'until the foremost rollers 114 in the Area of a tipping edge 131 can no longer be supported by the vibration conveyor 119. After reaching a tipping position, the rollers 114 will fall off the vibrating conveyor 119 due to the force of gravity, the tipping edge 131 being arranged relative to the rollers 116, 116 ′ such that the rollers 114 with their longitudinal extension are essentially perpendicular between the rollers 116, 116 'occur. Here, the rollers 114 come into the gap-forming distance 118 between the rollers 116, 116 ′, wherein in this gap-forming distance 118 the packaging material 115 of the rollers 114 is damaged in a manner which is explained in more detail in FIG. 6, and the coins 4 are thus released.

The rollers 116, 116 'are driven by two drive units 117, which are schematically identified as electric motors, a funnel 126 being provided below the rollers 116, 116' to catch the coins 4 falling out of the rollers 114. The coins 4 or the damaged packaging material 115 with the remaining coins 4 arranged therein falls in the direction of failure 125 due to the force of gravity and can then be fed from the hopper 126 again via downstream processing stages which are not shown. The entire system is constructed schematically on a frame 124, which frame 124 can be adapted both in height and in extent to an overall system described later.

In FIG. 6, the mode of action of the rollers 116, 116 'when the rollers 114 are unrolled with coins 4 arranged therein can be seen better. The rollers 116, 116 'carry profiled toothings 121 on their upper side, which remind, for example, of the toothing of gear wheels or the like. In the embodiment according to FIG. 6, these profiles 121 run approximately parallel to the axis of rotation of the rollers 116, 116 ', the two rollers 116, 116' each rotating relative to one another in the direction of rotation 120. A gap 1 18 is set between the rollers 116, 116 ', which essentially corresponds to the outside diameter of the rollers 114, the gap 118 forming the gap being selected to be somewhat smaller than the diameter of the rollers 114. As a result, the tips of the profiles 121 interact with the packaging material 115 of the rollers 114 when the rollers 114 pass through, as a result of which the packaging material 115 is locally is torn and the coins 4 arranged in the roll 1 14 can fall out of the roll 114. For this purpose, the roller 114 indicated on the upper side of the roller pair 116, 116 ', which passes through the rollers 116, 116' with its longitudinal axis essentially vertically from top to bottom, is passed through in the region of the rollers 116, 116 'which is closest to one another the profiles 121 are gripped and at the same time thereby conveyed through the area 1 18 forming the gap. The tips of the profiles 121 press into the packaging material 115 of the rollers 114, the opposing profile teeth of the profiles 121 forming a kink of the approximately rod-shaped roller 114. Figuratively speaking, the roller 114 is bent once or several times between the adjacent profile teeth of the profiles 121, as a result of which the packaging material 115 of the rollers 114 is damaged at at least one of the engagement points of the profiles 121. At the same time, the effect of tearing open the packaging material 115 of the roller 114 can be improved by rotating one of the rollers 116 'or 116 at a higher rotational speed than the other roller, as a result of which the packaging material 115 of the rollers 114 is additionally torn. When the roller 114 passes through the gap 118 forming a gap, such a roller 114 usually connects several times to successive profiles 121 of the rollers 116, 116 ', so that the packaging material 115 tears open repeatedly on a roller 114 . The pieces of money 4 tightly bundled in the form of the roll 1 14 can easily fall out of the packaging material 115 after this narrow formation of the container has been released, as is shown below the passage point with a roll 114 that has already passed through. This roller 114 has several kinks at which the packaging material 115 is torn in whole or in part, so that the coins 4 can easily fall out of this torn packaging material 115.

The degree of destruction of the package 115 can easily be influenced by the ratio of the size of the gap-forming distance 118 and the outer diameter of the rollers 114. For this purpose, the position of the rollers 116, 116 'is continuously adjustable relative to one another, for which purpose an adjusting mechanism (not shown) can be provided. This adjustment gear can then be used, for example, depending on the diameters of the rollers 114 of different pieces of money 4 to form the gap stood 1 18 between the rollers 1 16, 16 'can be changed so that, for example, the best possible degree of tearing of the packaging material 115 can also be set as part of tests.

It is of course also conceivable, but not shown in FIGS. 5 to 7, that the rollers 114 are not aligned in line alignment with one another on the vibration conveyor 119, but rather that they are arranged relative to one another such that they are approximately parallel to one another and when Incident in the gap forming distance 118 between the rollers 116, 116 'are arranged approximately parallel to the axis of rotation of the rollers 116, 116'. For this purpose, the profiles 121 of the rolls 1 16, 1 16 'are then arranged not parallel, but transversely to the axis of rotation and approximately radially on the outer circumference of the rolls 1 16, 116', so that again a configuration for the bending of the rolls 1 14 results. However, the various sections of the rollers 114 simultaneously pass through the effective area between the rollers 116, 116 ′ and are bent at several points at the same time.

FIG. 7 shows, in a variation to improve the positionally stable entry of the rollers 114 into the gap 118 forming the gap between the rollers 116, 116 ', a slide-like intermediate member 132 between the tipping edge 131 and the rollers 116, 116', which the rollers 114 assisted when falling from the vibration conveyor 119 until shortly before entering the gap 118 between the rollers 116, 116 'and thus prevents that, for example, rollers 114 which tilt over the tipping edge 131 collide with one another and their orientation in relation to the gap forming the gap 118 change.

FIGS. 8 and 9 show, in a side view and in a top view, an unpacking station 129, designated as a whole with the item number 167, for sack-like packages 135, with both individual coins 4 and packages 114 packed in rolls 114 in the sack-like packages 135 4 can be included. The money bags 135 are unpacked here by means of a slitting device 138, which can consist, for example, of a hard-metal or diamond-tipped disc or roller which rotates at high rotational speed and against which the money bags 135 are counter-conveyed by a conveyor device 133, which is described in detail. The cutting of the roller or Discs penetrate into the material of the money bag 135 and slit it open over a large area or tear this money bag 135 completely in the lower region. As a result, the money bags 135 suspended in the conveyor 133 can no longer hold their contents, which falls down under the influence of gravity into a drop hopper 143 arranged below the device, from which the coins 4 or rolls 114 are then, for example, a validation station 2 or an unrolling station. can be fed on 128.

The conveyor 133 for the hanging transport of the money bags 135 here consists of two essentially symmetrically arranged link chains or the like, which circulate endlessly via deflection pinions 161. In a substantially parallel portion of the path of the link chains 133, the link chains 133 are pressed against one another by means of press bars 163 elastically preloaded with springs 164 in such a way that a money bag 135 entering this area of the path is clamped between the link chains 133, which are pressed approximately parallel to one another and under pressure and is conveyed in the direction of flow 165. In this case, the money bag 135 hangs on its end, which is closed but intended for opening, in which usually no coins 4 or rolls 114 are also filled up to this fill level.

The money bags 135 are conveyed to the link chains 133 via a conveyor belt 134 after they have been set up in an approximately upright position in a feed station 136 on the conveyor belt 134. This is particularly advantageous if the money bags 135 can be set by hand at an ergonomic height in the loading station 136, for which purpose a height adjustment 137 is provided for the conveyor belt 134. After reaching the essentially horizontal section of the conveyor belt 134, the money bags 135 enter a separating funnel 166, which opens into a section of the conveyor belt 134 delimited by approximately parallel walls. This section, delimited by parallel walls, then conveys a single money bag 135 in the direction of flow 165 into a tapered area between the inlet-side pinions 161 and deflection pinions 162, whereby each money bag 135 is gripped by the link chains 133 and into the then approximately parallel area of the press bars 163 be promoted. The money bag 135 hanging in this way is detected on its path by a sensor 168, the money bag 135 remaining after passing through this sensor 168 in front of the slitting device 138 or being conveyed only slowly. The protective device 138 can then tear open the packaging material of the money bag 135 in the manner already described, whereupon a large part of the money pieces 4 or the rolls 114 from the money bag 135 will be omitted. For complete emptying, the money bag 135 can then be transported further to a knocking station 140, which, for example, processes the slashed money bag 135, which may also contain coins 4 or rolls 114, via an eccentrically rotating element in such a way that any coins 4 or coins 4 that may still be present Rollers 114 also fall out. The completely emptied money bag 135 is then transported up to the rear sprockets 161 in the direction of flow 165, where it is released by the chains 133 and can fall onto a slide 157, behind which, for example, a collecting container for emptied money bags 135 is arranged.

It should also be pointed out that both the slitting device 138 and the tapping device 140 can be arranged in a height-adjustable manner in the adjustment direction 158 in order, for example, to be able to slit or knock out different money bags 135 at their intended location and thus different sizes or degrees of filling of money bags 135 can be compensated.

The link chains 133 are driven by a drive motor 139 and a gear 141, which transmits to a drive shaft 142, on which the driven pinion 161 is then arranged. The entire unpacking device 129 can be constructed on a frame 144, which can also be adapted to an overall system as required.

FIG. 10 shows a very schematic representation of a basically conceivable structure of a system for unpacking and devaluation, which in particular may also include the devices shown in FIGS. 5 to 9. Unpacking begins in the unpacking station 129, into which money bags 135 are filled and torn open, and these rolls 114 are fed via a conveyor belt 134 to the unrolling station, designated 128 as a whole. At the exit of the unrolling station 128, the batch of money coins zen 4 and parts 159 of the packaging material 115 placed on a vibration conveyor 130, which produces an arrangement of the coins 4 and the packaging parts 159 in a few layers from the pile. This arrangement is then placed on an inclined conveyor 149, which feeds the coins 4 and the packaging parts 159 to a drop tower 147, in which a separation between coins 4 and packaging parts 159 takes place by means of baffles 148 and a vacuum generated by a cyclone 146. Before this, the coins 4 run past the inclined conveyor 149 past a selection station 150, which for example in the batch still pulls out magnetically active residual substances, such as wires for binding the money bags 135 or the like, for example by means of an electromagnet.

Within the drop tower 147, which causes the zigzag-shaped falling movement of the coins 4 with internal chicanes 148, a flow of the air passing through is generated vertically from bottom to top by a cyclone 146, so that the specifically lighter packaging parts 159 during the falling movement of the batch in the drop tower 147 can be separated from the coins 4 and withdrawn into a collecting container 160 via a corresponding suction arrangement. An exhaust air filter 151 can also be provided, which cleans the exiting air again from dust and small packaging pieces 159. Such separation techniques are fundamentally known and are therefore not to be described further here. It is also conceivable to use an also known NE separator or a station for wet flotation at this point in order to separate the packaging parts 159 from the coins 4. At the end of the drop tower 147, the coins 4 largely freed from packaging parts 159 fall onto a feed point 12 of an inclined conveyor 5, which feeds the coins 4 here to a parallel arrangement of two cancellation stations 2. These cancellation stations 2 are formed in the manner already described, for example by rollers 1, 1 ^' , the coins 4 being brought into a single-layer arrangement by means of a stripper 7 and being fed to the two cancellation stations 2 via a horizontal conveyor 6. Below the devaluation stations 2, the devalued coins 3 fall onto a discharge belt 152 and can, for example, be fed to a weighing device (not shown). Such a continuous The general structure of a system according to the invention permits largely automatic unpacking and devaluation of circular-shaped workpieces 4, in particular of coins 4, free of manual operations. It is also conceivable that such a system has only parts of the devices shown here, depending on the task and the type and number of processing operations required. It is also conceivable that each of the individual devices is present several times in order to increase the throughput of the system as a whole.

FIG. 11 shows an arrangement of a system according to the invention according to FIG. 10 on a trailer 154 which, for example, makes the entire system transportable and easy to bring to the respective installation and deployment location. In addition to the system components already shown in FIG. 10, a forklift 153 for transporting containers and coins 4 is also provided, as well as a weighing station 156, on which quantity checks of the processed coins 3, 4 can be carried out, for example, before and after processing and devaluation. The autonomous power supply can be recognized by means of a power supply cabinet 155, which enables the entire system to be operated largely independently of the mains. With a transportable device of this type, it is also conceivable, for example, to offer the devaluation service only when required on site at money-emitting institutions, without these having to invest large sums in the acquisition and operation of corresponding systems.
