Description

The invention relates to a system for processing round parts in the manufacture of coins.

Coins are known in different designs. There are coins that are minted from a one-piece, disc-shaped disc. Other coins are composed of two or three round parts. For example, the 1-euro coins or the 2-euro coins each consist of two round parts, namely a round outer ring and a round core. Two or more round parts from which a coin is to be made are inserted into one another before the coin is minted. For example, they can have different colors or consist of different materials.

Known coin minting systems are set up for the production of certain types of coins or coin types. If one-piece coins are minted, the correspondingly preformed rounds can, for example, only be fed to a minting press, minted there and then removed again. In the case of multi-part circular blanks, the circular part must first be inserted into one another and then embossed. The systems required for different coin types differ in terms of effort and size. These types of plants are used in the GB 2493059 A , US 4,287,748 A and EP 0 511 551 A described. Based on this, it can be considered an object of the present invention to simplify the production of different types of coins.

This task is carried out by a system with the Features of claim 1 solved.

• die Art und/oder die Anzahl der Arbeitsschritte zur Herstellung der Münze verschieden ist und/oder
• die Anzahl der Rondenteile verschieden groß ist und/oder
• eine Münze nur Rondenteile aus metallischen Materialien bzw. Legierungen aufweist, während die andere Münze wenigstens ein Rondenteil aufweist, das Kunststoff enthält.

The system according to the invention is set up for processing and / or measuring and / or testing round parts in the production of coins of different coin types. A coin can be minted from at least one round part. The system is set up to be able to manufacture one, two or more coin types or to process, measure or test round parts for two or more coin types. Two coins belong to different coin types if:

• the type and / or the number of work steps for producing the coin is different and / or
• the number of round parts is of different sizes and / or
• one coin has only round parts made of metallic materials or alloys, while the other coin has at least one round part that contains plastic.

For example, in the case of multi-part blanks, the individual parts of the blanks have to be inserted into one another (additional work step), which is not necessary in the case of another type of coin comprising only a one-piece, disc-shaped blank. Thus there are different coin types in the sense of the present application. Two three-part coins are also different types of coins if one coin only has metallic round parts, while the other coin e.g. contains a plastic inner ring.

The system has several stations, each of which is set up to have at least one part of a round Machining and / or measuring and / or checking the circular blank for producing a coin type. At least one station can also be used to feed a round part for further transport to one or more other stations of a first transport device or to discharge it from the first transport device.

The first transport device has at least one receptacle for the at least one round part of the round to be transported, by means of which the round part in question can be transported in the receptacle between the existing stations. Several separate transport devices can also be present. The at least one transport device can be formed by a gripper or manipulator, by a transport device which can be driven rotatably about an axis of rotation, by a linear transport device or a combination thereof.

The system has a control device. This is set up to control the existing stations depending on the coin type to be produced and to activate the stations required for the production of the coin type, while the other stations are deactivated. If a coin type of the maximum possible complexity is thus produced, all existing stations can be activated and used in the production of the coin. If a different coin type is to be produced, one or more of the existing stations can remain unused and are deactivated accordingly. The stations themselves remain arranged on the first transport device. A complete dismantling or reconstruction of a station when converting production to another coin type is not necessary.

The control device is also set up to control the first transport device as a function of the coin type of the coin to be produced and to thereby specify the transport sequence in which the at least one round part used to produce the coin type is transported between the active stations. If several blank parts are required for a blank, each blank part can run through different stations or stations in different orders. It is possible that a round part is also fed to a passive station, but is not processed, measured or checked there, but only remains in a passive station until further transport.

The system can be used very flexibly to produce different types of coins. The control device is given the type of coin to be produced and this then controls the first transport device and the stations as a function thereof. Processing and / or measurement and / or testing of at least one round part takes place in the active stations, while no processing, measurement or testing of a round part takes place in passive stations.

The passive stations are brought into a passive state or in an idle state in which they enable unimpeded transport of the round parts by means of the first transport device.

In one embodiment, the number of active stations for two types of coins that can be produced is different.

• eine Zuführstation für ein Rondenteil;
• eine Station zum Ineinandersetzen bzw. Ineinanderfügen von wenigstens zwei Rondenteilen;
• eine Station zum Umformen eines Innenrandes eines Rondenrings oder eines Außenrandes eines Rondenkerns;
• eine Station zum Stauchen eines Randes eines Rondenteils;
• eine Station zum Glühen wenigstens eines Rondenteils;
• eine Station zum Reinigen der Oberfläche wenigstens eines Rondenteils;
• eine Station zum Stanzen oder Lochen eines Ausgangsteils zur Herstellung eines Rondenrings und/oder Rondenkerns;
• eine Station zum Messen oder Prüfen wenigstens einer Abmessung wenigstens eines Rondenteils;
• eine Station zum Bedrucken wenigstens eines Rondenteils;
• eine Station zum Kalibrieren der Position oder Ausrichtung eines Rondenteils gegenüber einem anderen Rondenteil oder gegenüber einem sonstigen Bezugssystem;

• eine Station zum Spritzgießen wenigstens eines Rondenteils;
• eine Prägestation zum Prägen der Münze aus einer einteiligen oder mehrteiligen Ronde.

One or more of the following stations can be used as stations:

• a feed station for a round part;
• a station for the interlacing or intermeshing of at least two round parts;
• a station for reshaping an inner edge of a round ring or an outer edge of a round core;
• a station for upsetting an edge of a round part;
• a station for annealing at least one part of the blank;
• a station for cleaning the surface of at least one round part;
• a station for punching or punching an initial part for producing a blank ring and / or blank core;
• a station for measuring or checking at least one dimension of at least one round part;
• a station for printing at least one round part;
• a station for calibrating the position or orientation of a part of the round with respect to another part of the round or with another reference system;
• a station for dispensing or discharging at least one part of the blank;
• a transfer station for transferring at least one round part to a second transport device different from the first transport device;
• a station for injection molding at least one blank part;
• a minting station for minting the coin from a one-piece or multi-piece blank.

Preferably at least one embossing station is Minting a coin available. It can be provided that there is a separate minting station for two different coin types. The different coin types can then be minted using an assigned minting station. Alternatively or additionally, it is also possible for an embossing station to have an interchangeable - for example automatically interchangeable - embossing tool. It is possible for the control device to be set up to cause the minting tool to be exchanged automatically, depending on the type of coin to be produced.

It is advantageous if a second transport device is present. The second transport device has at least one receptacle for the at least one round part to be transported. The second transport device is in particular provided and set up to transport the at least one blank part to the stamping station. As an alternative or in addition, the second transport device can also be set up to remove the coin minted in the minting station from the minting station.

The first transport device and / or the second transport device can each be set up to transport the round parts to be transported in each case on a predetermined circular path. For this purpose, the first and / or second transport device can be formed, for example, by a respective turntable. The turntables can be arranged in planes aligned parallel to one another or in a common plane, for example in a horizontal plane. Each turntable can preferably be driven by means of a rotary drive about an axis of rotation, in particular can be driven step by step.

The first and / or second transport device can accommodate a plurality of receptacles for each or a plurality of blank parts. In the case of execution by a turntable in question, receptacles or pockets for one or more round part portions can be present evenly distributed along a circular path.

It can be advantageous if the first and / or second transport device can be adapted to the type of coin to be produced. For example, one or more receiving parts of the transport device in question, which have the at least one receptacle, can be adaptable or exchangeable and can therefore be adapted to the type of coin to be produced or exchanged depending on the type of coin to be produced.

It is preferred if a station is designed as a transfer station which is set up to transfer the at least one round part from the first transport device to the second transport device.

The temporal characteristic of the transport movement of the first transport device can be different from the second characteristic of the transport movement of the second transport device. In the case of a clocked transport, the respective time cycles can be of different sizes. Depending on the design of the transfer station for transferring the round parts arranged in a receptacle of the first transport device into a receptacle of the second transport device, the transport movements of the two transport devices can also be carried out completely independently of one another.

In one embodiment, the control device is set up to design the first transport device in this way to control that the at least one round part is transported between the stations in a first time cycle. Alternatively or additionally, the control device can be set up to control the second transport device in such a way that the at least one round part, which is transported by means of the second transport device, is transported in a second time cycle, in particular to the embossing station.

In one exemplary embodiment, the at least one receptacle of the first transport device and / or the second transport device is clocked or moved intermittently between predetermined positions, for example rotational positions. Each existing recording is thus moved on at the specified time interval. A standstill is provided between two gradual movements. The downtimes for the first transport device and the second transport device can be of different sizes. The downtime is required for processing, measuring, testing, etc. at least one part of the round present in a station.

As an alternative to the intermittent movement, the transport device concerned can also be moved without a stop. For example, a continuous movement can be carried out with a constant speed or with a speed that changes depending on the position. The speed can be lower, for example, in the area of the stations or the predetermined positions and the at least one round part can be transported between the stations or the predetermined positions at a higher speed.

It is possible for at least one of the stations assigned to a transport device to be the master the time control for the transport device specifies and the control of the other stations is adapted to it.

It is also advantageous if at least one stamping station is assigned to the second transport device and the second timing or the time characteristic of the transport movement is adapted to a lifting movement of a press ram of a stamping press of the at least one stamping station. Such embossing presses run fast and must be operated with a minimum number of strokes. It is important that during the operation of the embossing press there is always a blank to be embossed in the embossing tool of the embossing press. A working stroke of the embossing press without a workpiece is avoided. For this purpose, either a new blank to be stamped is fed in at each stroke or, if this is not possible, the blank is left in the stamping press over two or more strokes until a new blank can be fed.

Each of the existing stations is preferably arranged at a fixed station location of the first transport device and / or the second transport device. The assignment of a station to a station location cannot be changed and is retained regardless of the coin type to be produced.

The stations are preferably arranged adjacent to one another along a circular path.

In a preferred embodiment, there are at least four or five stations.

Preferred exemplary embodiments of the invention are described in detail below with reference to the attached drawing explained. Show it:

• Figure 1 2 shows a basic circuit diagram of a system with two transport devices, each of which is assigned a number of stations,
• Figure 2 1 shows a schematic representation of an exemplary embodiment of a system with several stations,
• Figure 3 1 shows a schematic representation of an embossing press that can be used in an embossing station of the system,

• Figure 5 a cross-section and a plan view of a second type of coin consisting of some disc-shaped circular part and
• Figure 6 a cross section and a plan view of a third coin type consisting of two round parts.

In Figure 1 is a highly schematic illustration of a basic example of an embodiment of a system 10 for producing coins 11 illustrated. Coin types differ in particular in that they require a different number of work steps or processing steps and / or a different type of processing.

In Figure 4 a first coin type T1 is illustrated. The coin shown there is produced from a round blank which consists of three round parts 12. In the first coin type T1, the three round parts 12 are separated by one Blank core 13, formed by a blank inner ring 14 and a blank outer ring 15. The blank rings 14, 15 are arranged coaxially to the blank core 13, the blank inner ring 14 being arranged between the blank core 13 and the blank outer ring 15.

A second coin type T2 is in Figure 5 illustrated. The coin 11 of the second coin type T2 shown there is made from a single circular part 12 which is formed by a circular disk 16.

A third coin type T3 is in Figure 6 illustrated. The coin 11 of the third coin type T3 is produced from two round parts 12, namely from a round core 13 and a round outer ring 15. In contrast to the first coin type T1, there is no round inner ring and the round core 13 and the round outer ring 15 are connected directly to one another.

The connection of several round part 12 can, as in the Figures 4 and 6 is illustrated, take place non-positively and / or positively. The form fit can be achieved when the coin is minted using an appropriate material flow.

While the coin of the coin type T2 consists of a uniform material, in particular of a metallic alloy, in particular of a metallic alloy, depending on the material used, further coin types can be formed on the basis of the illustrated multi-part coin types T1 and T3, for example the round parts 12 made of different materials exhibit. A circular part 12 can each be made of a metallic alloy or of plastic or a composite material. The in Figure 4 The first coin type T1 shown has, for example Blank outer ring 15 and a blank core 13 each made of a metallic alloy, while the blank inner ring 14 consists of plastic. In another type of coin, the inner ring 14 of the disc could be made of a metallic alloy.

The coins 11 are illustrated here only as examples as circular coins. It goes without saying that other external contours can also be used, for example polygonal contours. The radial dimensions of the round parts 12 can also vary.

The schematically in Figure 1 The illustrated system 10 has at least one transport device and, in the exemplary embodiment, a first transport device 20 and a second transport device 21. Each transport device 20, 21 has at least one receptacle 22. In the receptacle, a circular blank consisting of at least one circular part 12 or a single circular part 12 can be accommodated and transported. In the exemplary embodiment, the transport devices 20, 21 each have a plurality of receptacles 22. The receptacles 22 are immovable relative to one another. In the exemplary embodiment, the receptacles 22 of each transport device 20, 21 are arranged along a circular path and, according to the example, are evenly distributed. The receptacles 22 of the first transport device 20 are arranged, for example, on a first turntable 23 and the receptacles 22 of the second transport device 21 on a second turntable 24. The dimensions of the receptacles 22 of the various transport devices 20, 21 can be of different sizes. According to the example, the recesses 22 of the second transport device 21 or the second turntable 24 have a larger cross-sectional area or a larger diameter than the receptacles 22 of the first transport device 20 or the first turntable 23.

The first transport device 20 has a first drive 25 and the second transport device 21 has a second drive 26. The two drives 25, 26 are, for example, as rotary drives for rotating the respective turntables 23, 24 about a first axis of rotation D1 or a second axis of rotation D2 ( Figure 2 ) set up. The drives 25, 26 can be controlled by a control device 27. The control device 27 generates a first drive signal A1 for the first drive 25 and a second drive signal A2 for the second drive 26. The drives can have electrical servo or stepper motors.

Instead of the two separate drives, it is also possible to provide only one drive which is mechanically coupled to both transport devices 20, 21. This mechanical coupling can coordinate the movements of the two transport devices 20, 21 instead of the control device 27.

In the exemplary embodiment, the drives 25, 26 are set up to move the receptacles 22 clocked or intermittently. For example, the turntables 23, 24 are moved by a rotary step movement about the respective axis of rotation D1 or D2 in one time cycle. The first time cycle for the movement of the first turntable 23 can be different in size than a second time cycle for moving the second turntable 24. After each rotation step movement, the turntables 23, 24 remain in their rotational position for a predetermined period of standstill. The standstill period in which the receptacles 22 of the first transport device 20 remain in their position can be different from the standstill period in which the receptacles 22 of the second transport device 21 in Stand still.

A plurality of stations 30 are arranged on the first transport device 20. The blank or the at least one blank part 12 can be moved in a receptacle 22 into each station 30 on the first transport device 20. The stations 30 on the first transport device 20 are preferably used to prepare the round blank for embossing. Each station 30 on the first transport device 20 serves to feed at least one round part 12 to the first transport device 20 and / or to remove it from the first transport device 20 or to process the at least one round part or to measure the at least one round part or to test the at least one Round part. Machining a round part is to be understood as any process that changes the shape of at least one round part 12 and / or changes the surface. The following processing steps can be carried out, for example, in one or more stations 30:

• Inserting or inserting several round part 12 into one another,
• Reshaping at least one round part 12, for example by molding a recess into an inner edge or outer edge of a round part 12 or by compressing a round part,
• Annealing at least one round part 12,
• Cleaning the at least one round part 12,
• Printing or coloring at least one blank part 12,
• Coating at least one round part 12,
• Cutting and / or punching and / or punching an initial part, for example for producing a round ring 14, 15 and / or a round core 13 from the initial part,
• Aligning or positioning two blank parts 12 relative to one another or with respect to the recess 22,
• Injection molding of a round part 12,
• Measuring and / or checking at least one round part 12.

If a station 30 is used for measuring or testing, contacting or non-contact measuring methods or sensors can be provided in this station. For example, at least one dimension or surface condition of a round part 12 can be determined and compared with predetermined target values.

In the exemplary embodiment, at least one feed station 31 is present. At least one round part 12, which is required for producing the relevant coin type T1, T2, T3 of the coin 11, can be fed via each feed station 31. It is also possible to feed round parts 12 already nested or nested into one another via a feed station 31 to the first transport device 20. At least one station 30 can also be designed at the same time as a feed station for a further round part 12 and for interlacing this further round part 12 with a round part 12 already present in a receptacle 22.

In addition to at least one feed station 31, at least one transfer station 32 is present, by way of example, by means of which a one-piece or multi-piece blank is transferred from the first transport device 20 to the second transport device 21.

At least one stamping station 33 is present on the second transport device 21. The embossing station is made up of one or more round parts 12 Round is fed via the second transport device 21, minted to the coin 11 of the relevant coin type T1, T2, T3 and removed again via the second transport device 21. At the second transport device 21, a station 30 can also be designed as a delivery station 34, at which the minted coins 11 are delivered or removed.

As it is shown schematically in Figure 1 is illustrated, all stations 30 are controlled by a control signal Si (i = 1, 2, 3, ..., n). The number of control signals corresponds to the number of stations 30 present Figure 1 eleven stations 30 are driven, so that correspondingly eleven control signals S1 to S11 are used for driving.

It is also possible to assign sensors to one or more stations, which transmit their measurement or sensor signals to the control device 27. The control device 27 can then control the relevant station 30 or another station 30 depending on the at least one measurement signal or sensor signal. For example, round parts 12 which are assessed as faulty can be conveyed into a station 30 for removal from the relevant transport device 20 or 21.

At least one embossing station 33 with an embossing press 40 is present on the second transport device 21. A highly schematic illustration of an embossing press 40 is shown in FIG Figure 3 shown. The embossing press 40 has a press drive 41 for driving a press ram 42 which is linearly movable in a stroke direction. An upper tool 43 for minting a coin 11 is arranged on the press ram 42. On a press table 44, a lower tool 45 is opposite in the stroke direction arranged to the upper tool 43. The upper tool 43 and the lower tool 45 form the embossing tool 46 for embossing the coin 11.

For each coin type T1, T2, T3 that can be produced in the system 10, there can be an assigned minting station 33. Additionally or alternatively, it is also possible to carry out a preferably automatically executable tool change of an embossing tool 46 of an embossing press 40, so that coins 11 of different coin types T1, T2, T3 can be minted in an embossing press 40 by a corresponding tool exchange of the embossing tool 46. In this case, a single stamping station 33 is sufficient.

As explained, the system 10 is set up to be able to produce coins 11 of different coin types T1, T2, T3. For this purpose, all stations 30 are available which are required for the production of coin types T1, T2, T3. Each station 30 is arranged at a fixed station location Pi (i = 1 to n) and remains set up there regardless of which coin type T1, T2, T3 is produced. The stations 30 are therefore not completely set up or completely dismantled depending on the type of coin to be produced. Rather, stations 30, which are not required in the production of a specific coin type, are deactivated by the control device 27 and, as it were, switched to an idle state. The stations 30 required depending on the coin type T1, T2, T3 to be produced are activated by the control device 27 and used in the production of the coins 11 of this coin type.

The control device 27 controls the two transport devices 20, 21 in such a way that the at least one round part required for producing the coin type 12 runs through a predetermined transport sequence through the stations 30. It can happen that at least one round part 12 is also transported to passive stations 30, but is neither measured nor processed there, but only remains in the passive station 30 between the two transport steps during the standstill phase in question, in order to then be transported further.

The second drive signal A2 for the second transport device 21 is adapted to the number of strokes of the stamping press 40 of the stamping station 33 on the second transport device 21. The blanks are transported in time into the embossing press 40 and out of the embossing press 40 in such a way that a round blank is arranged between the upper tool 43 and the lower tool 45 during each working stroke of the press ram 42. An idle stroke without a blank in the embossing tool 46 is avoided. With each working stroke of the press ram 42, a blank to be minted can be fed and a minted coin 11 can be removed. It is also possible for the press ram 42 to carry out two or more working strokes on the same round blank before it is removed again from the stamping press 40. According to the example, the embossing press 40 must always be operated with a certain minimum number of strokes in order to provide sufficient kinetic energy in the press ram 42. For example, 300 to 400 strokes / min. required.

The two transport devices 20, 21 are mechanically decoupled and can be moved independently of one another in time via the two drive signals A1, A2. Therefore, the stations 30 and the first transport device 20 can be timed independently of the set and required number of strokes of the embossing press 40 can be controlled, which enables a high degree of flexibility. The first transport device 20 and the stations 30 arranged thereon are controlled by the control device 27 depending on the coin type T1, T2, T3 of the coin 11 to be produced, and are clocked accordingly.

Figure 2 shows an exemplary selection of stations 30 for an exemplary embodiment of a system 10. At the first station location P1 there is a first feed device 31 for feeding a circular outer ring 15. Viewed clockwise, there is a station 30 adjacent to it at the second station location P2 for reshaping the outer ring 15 of the blank. At a third station location P3, a station 30 is provided for feeding and inserting a plastic inner ring 14 into the outer ring 15 already supplied. At a fourth station location P4, a station 30 is provided for feeding and inserting a metallic blank inner ring 14 into the supplied blank outer ring 15. Since plastic rings and metallic rings behave completely differently during transport and fitting together due to the different mass and the different spring stiffness, there are two separate stations 30 here, which can be activated as an alternative to one another depending on the coin type.

A station 30 for testing is then present at a fifth station location P5, in which it is checked whether the inner ring 14 has been correctly inserted into the outer ring 15. If this is not the case, incorrectly inserted rings 14, 15 can be removed at this station 30.

There is a station at a sixth station location P6 30 for feeding and inserting a round core 13. The blank core 30 is inserted into the at least one blank ring 14, 15.

At a seventh station location P7 there is a station 30 for checking whether the round core 13 has been correctly inserted into the at least one round ring 14, 15. This part of the station can also be used to remove incorrectly inserted round parts.

At an eighth station location P8, the transfer station 32 is provided, by means of which the one-part or multi-part blanks are transferred to the second transport device 21.

An embossing station 33 is provided on the second transport device 21 at a ninth station location P9 and at a tenth station location P10. The minting stations 33 are provided for minting different types of coins. A delivery station 34 is present at an eleventh station place P11.

The stations 30 specified above serve only to illustrate a possible configuration of a system 10 and are only examples. Depending on which different coin types T1, T2, T3 are to be produced, the system 10 can also have more or fewer stations 30 or other stations 30. The stations for testing can be omitted, for example. It is also possible to provide only one checking station for checking the minted coins 11. This can be arranged in front of the dispensing station 34 or can be integrated into the dispensing station 34 and can separate the defective coins separately.

Is by means of the Figure 2 illustrated system 10, a three-part coin with a round inner ring 14 made of plastic, the control device 27 activates the stations 30 at the station locations P1, P2, P3, P6, P8, P10 and P11. As an option, the stations can also be activated for testing at station positions P5 and P7. If, for example, a one-piece coin of the coin type T2 is to be produced, the disk 16 can be fed via the feed station 31 at the first station location P1 and transferred via the transfer station 32. All other stations 30 on the first transport device 20 can then be deactivated. To mint this coin, for example, the embossing station 33 is activated at the station location P9 and the embossing station 33 is deactivated at the station location P10.

The first transport device 20 and / or the second transport device 21 can be modified to transport different types of coins in which the round parts 12 have different diameters or dimensions. For example, the dimensions of the receptacles 22 can be adapted to produce coins of different sizes. For example, it is possible to design the first turntable 23 and / or the second turntable 24 interchangeably, or to carry out receiving parts of the turntables 23 and / or 24, which contain the receptacle 22, interchangeably. Depending on the type of coin to be produced, the structural modifications can then be made to the transport devices 20 or 21.

The invention relates to a flexible system 10 for producing at least two coin types T1, T2, T3 from coins 11 to be produced. In particular, the different coin types T1, T2, T3 have different numbers of round parts 12 and / or round parts 12 from different ones Materials on. In the case of the different coin types T1, T2, T3, the type and the number of work steps which are necessary for producing the coin 11 of the coin type T1, T2, T3 in question differ. The system 10 has a number of stations 30, in each of which a round part 12 is fed and / or delivered and / or processed and / or measured and / or checked. At least one transport device 20, 21 serves to transport the at least one round part 12 between the stations. Preferably, there are two independently controllable transport devices 20, 21 which work together for the at least one round part 12 via a transfer station 32. A control device 27 controls the at least one transport device 20, 21 and the stations 30 depending on the type of coin to be produced.
