EP3349992B1 - Transport device for transporting coin blanks and method for producing a coin - Google Patents

Description

The invention relates to a transport device for transporting coin blanks, which are referred to as blanks, and/or their components to a minting station. The invention also relates to a method for producing coins from blanks. In particular, these are multi-part blanks with at least one ring and a disc-shaped core.

DE 100 57 000 A1 shows a transport device according to the preamble of claim 1, with two transport parts, each having transport pockets. Round cores for the multi-part coin are placed in the transport pockets of the first transport part. Outer rings for a multi-part coin are placed in the transport pockets of the second transport part. The blank cores are inserted into the outer rings at a joint and the assembled multi-part blank is transported to a stamping station via the second transport part. Nothing is disclosed about the play between the inner discs or the outer rings and the transport bags.

Out of GB 2 493 059 A a method and a device for producing a bimetallic coin is known. Outer rings are transported via a belt to a joining station for inserting blank cores and, together with the inserted blank cores, to a transport disc with transport bags.

DE 3742745 A1 describes a minting machine for ring-core coins. In doing so, rings are in a first place fed to a revolver plate. At another point, cores are inserted into the rings on the turret plate. The blanks, consisting of a ring and a core, are then fed to a stamping station via the turret plate.

DE 10 2013 06375 A1 also describes a transport device for transporting blanks with a ring and a core to a stamping station. At one point, the core is inserted into the hole in the ring via a pressing device and then transported further to the stamping station via the transport device.

Insertion of a blank core into the blank ring requires precise alignment of the core to the ring to allow for insertion. In the case of non-circular blanks that are processed before embossing, precise positioning and/or orientation of the rotational position of the blank about its blank axis is also required, for example if a hole and in particular an out-of-round hole is made.

It can therefore be regarded as an object of the invention to enable improved positioning and/or orientation of the blanks at a pre-processing station before embossing when the blanks are being transported to an embossing station.

This object is achieved by a transport device having the features of patent claim 1. The invention also proposes a method for producing a coin using the transport device according to claim 7.

The transport device according to the invention has a drivable first transport part. The first transport part can preferably be formed by a first turret plate. The first transport part has a plurality of first transport pockets, with exactly one blank being able to be transported in each first transport pocket. There is a first clearance between the outer contour of the blank and the inner contour of the first transport bag. As a result of this first play, the blank can move in one plane, ie in two dimensions, within the first transport bag.

The transport device also includes a second transport part, which can preferably be formed by a second turret plate. The second transport part has a plurality of second transport pockets, with exactly one round blank being able to be transported in each second transport pocket. There is a second clearance between the outer contour of the blank and the inner contour of the second transport bag. The second game is bigger than the first game. Thus, the movement of the blank in a plane in a second transport bag relative to the transport part is greater than in a first transport bag.

The first and/or second transport pockets can be partially or completely closed around the blank in the circumferential direction. They grip the blank in such a way that the blank is held in the respective transport bag during transport. The transport pockets are preferably open at right angles to the circular blank on both sides in a vertical direction. During the movement of the relevant transport part, the blanks slide on a corresponding one support along its trajectory.

The movement path or transport path of the blanks in the first transport part and/or in the second transport part preferably corresponds to a circular path. The movement along such a circular path can be easily synchronized with the processing of the blanks, for example the embossing of the blanks by an embossing press at the embossing station or the introduction of a hole by a punching device at a punching station or the insertion of a core in a ring of the blank by a Joining device at a joining station.

At a transfer point, the blanks are transferred from the first transport part to the second transport part. The embossing station, where the blanks are embossed to produce the coins, is assigned to the second transport part. The second transport part is set up to transport the blanks from the transfer point to the embossing station or the embossing press and out of the embossing station. The second game of the second transport pockets is large enough to accommodate the embossed coin, the area of which is larger than that of the blank. Due to the fact that the first play between the blanks and the first transport pockets of the first transport part is smaller, the blanks are positioned more precisely in the first transport pockets and can be processed easily and precisely, for example at a punching station for making the hole in a blank disc or a forming station for forming an inner edge of a blank ring or a joining station for joining a core in the ring of a blank. This simplifies the pre-processing of the blank before embossing. A high output when minting coins can also be achieved by means of the transport device.

Each blank has several components, in particular at least one ring with a hole and a core that is inserted into the hole. A blank can also consist of more than two components and can have, for example, an outer ring, an inner ring and a core. The materials of the components can be different. A metal or a metal alloy or plastic can be used for each component of the blank.

At least one preparation station is arranged adjacent to the first transport part and is set up to prepare the blanks for a subsequent embossing process. The at least one preparation station has a joining station which is set up to join at least two components of the blank, for example a core and a ring or an outer ring and an inner ring. In addition or as an alternative, a preparation station can also be a perforation station, in which a hole is made in a round disk in order to be able to insert an inner ring or a core there. A corresponding punching or cutting device or another suitable separating device can be provided at the punching station in order to make a hole in the blank disc. Additionally or alternatively, a preparation station can also be a forming station for forming an inner edge of a blank ring, to which a blank ring is fed for forming and which can follow a punching station, for example.

It is also advantageous if a control device is present. The control device can be used, for example, to coordinate the different stations and/or drives of the transport parts. The control device is set up in particular to control and in particular to synchronize a first drive for the first transport part and a second drive for the second transport part. In particular, the embossing press at the embossing station and/or a separating device at the punching station and/or a joining device at the joining station and/or a forming device at a forming station are controlled in a coordinated manner with the two drives.

In an advantageous embodiment, the two drives are set up as stepper drives. They are rotated by the control device stepwise or intermittently by a predetermined angle of rotation about the respective axis of rotation.

As an alternative to this, it is also possible for the two drives for the transport parts to have a common drive motor and for each gear to produce the desired movement to be present between the drive motor and the relevant transport part. The synchronized movement is achieved through a mechanical coupling.

The number of first transport pockets on the first transport part is preferably greater than the number of second transport pockets on the second transport part. For example, the diameter of the first turret plate can be larger than the diameter of the second turret plate, so that a larger number of first transport pockets can be arranged on the first turret plate. Several preparation stations can also easily be arranged on the first transport part.

The method of making a coin according to the invention is as follows:
First, a blank is transported to the transfer point in a first transport pocket of the first transport part. At the transfer point, the blank is transferred to the second transport part and picked up there in one of the second transport pockets. The blank is then moved to the embossing station in a second transport pocket of the second transport part. A coin is minted from the blank at the minting station. The minted coin is moved out of the minting station with the aid of the second transport part.

During transport, the blank is prepared by means of the first transport part at at least one preparation station for the subsequent embossing. In particular, an inner component, for example a core or an inner ring, is inserted into an outer component, for example an inner ring or an outer ring, at a joining station. In order to produce a ring, a punching station can also be present in order to produce a ring of the blank from a blank disk.

In the 1 and 2 is a schematic of an embodiment of a transport device 15 for transporting blanks 16 ( 10 ) to an embossing station 17 with an embossing press 18 and from the embossing station 17. The transport device 15 has a first transport part 19 with a plurality of first transport pockets 20 . The first transport part 19 is formed, for example, by a first turret plate 21, which can be driven step by step about a first axis of rotation D1 by means of a first drive 22. The first transport pockets 20 are distributed uniformly around the first axis of rotation D1 in the circumferential direction.

The transport device 15 also includes a second transport part 26 with a plurality of second transport pockets 27. The second transport part 26 is formed by a second turret plate 28 which can be driven in steps about a second axis of rotation D2 via a second drive 29. The two axes of rotation D1, D2 are aligned parallel to one another. The second transport pockets 27 are distributed uniformly in the circumferential direction about the second axis of rotation D2 on the second turret plate 28 . The number of second transport pockets 27 is smaller than the number of first transport pockets 20. The diameter of the second turret plate 28 is smaller than the diameter of the first turret plate 21.

The circular path along which the first transport pockets 20 are arranged has a larger diameter than that Circular path along which the second transport bags are arranged. The first transport bags 20 are smaller than the second transport bags 27.

The two drives 22, 29 would be controlled and coordinated by a control device 30, so that the indexing movements of the two turret plates 21, 28 are synchronized.

At a transfer point 34 , the transport device 15 is set up to transfer the blanks 16 transported by means of the first turret plate 28 to the second turret plate 21 . In the exemplary embodiment, the transport of the blanks 16 at the transfer point 34 is carried out or supported by gravity. In addition, a transfer device that can be controlled by the control device 30 can also be present. For example, the two turret plates 21, 28, viewed parallel to the axes of rotation D1, D2, can be offset in different planes and overlap at the transfer point 34 in such a way that a blank 16 can be transported or dropped from a first transport pocket 20 into a second transport pocket 27 can. Optionally, the movement can be supported or carried out by a transfer device.

In contrast to what is illustrated in the drawing, there can also be a transfer device that can be controlled by the control device 30 in order to transport the circular blank 16 from a first transport pocket 20 into a second transport pocket 27 . This can also be done against gravity. The first revolver plate 21 can also be located vertically below the second revolver plate at the transfer point 34 28 can be arranged. A ram or the like, which lifts the blank 16 from the first transport pocket 20 into the second transport pocket 27, can serve as the transfer device at the transfer point 34.

Below each revolver plate 21, 28 there is a support surface 35 for the blanks 16 or embossed coins in the transport pockets 20, 27. The turret plates 21, 28 rotate relative to the respective support surface 35, as a result of which the blanks or coins are moved in a sliding manner on the support surfaces 35. The support surfaces 35 are present on suitable sides of corresponding support parts 36, which are assigned to the transport bags 20, 27 and which are in 2 are only illustrated in a very schematic way.

The second transport part 26 or the second turret plate 28 is used to transport the blanks 16 from the transfer point 34 to the embossing station 17 and to transport finished coins from the embossing station 17 to a removal point 40. At the removal point 40, the finished coins are removed from the second transport part 26 released.

The first transport part 19 or the first turret plate 21 transports the blanks to the transfer point 34. Depending on the design of the blanks 16, one or more feed points 41 for components of the blanks 16 are present. In the exemplary embodiment, two feed points 41 are present. A blank disc 42 is fed in at one feed point 41 . A core 43 is fed to the blank 16 at a further feed point 41 . Between the two feed points 41 there is a punching station 44 on the one hole 45 ( 8 ) is introduced into the round disk 42 in order to produce a ring 46 from the round disk 42 . Following the piercing station 44 there is a joining station 47 at the feed point 41 for the cores 43 . The cores 43 are inserted into the rings 46 of the blank 16 at the joining station 47 . The blanks 16 with the cores 43 ( 10 ) transported to the transfer point 34 by means of the first transport part 19 and the first turret plate 21. The first transport part 19 therefore transports the multi-part blanks 16 and also individual components thereof (rings 46) in the first transport pockets 20.

In 8 It can be seen schematically that in the piercing station 44 an annular concave indentation can be made on the inside of the ring 46 ( 8 ). This forming process can also be carried out in a separate forming station. When the blank 16 is embossed, material of the core 43 is displaced and flows into this depression, so that a form-fitting connection is created between the core 43 and the ring 46 . Instead of an annular all-round indentation, other types of indentations or recesses could also be present on the inside of the ring 46 in order to create the positive connection between the core 43 and the ring 46 . As a result of this form fit, the forces that are necessary to press the core 43 of a minted coin out of the ring 46 are sufficiently large and meet the requirements of the mints.

In the Figures 3 to 6 are exemplary embodiments for a first transport bag 20 ( 3 and 5 ) and for a second transport bag 27 ( 4 and 6 ) illustrated. The transport bags 20, 27 at the Figures 3 and 4 each have a circular shape. The shape of the transport bags can vary depending on the shape of the blanks 16. In the embodiment according to the Figures 5 and 6 the transport bags 20, 27 have a polygonal shape and are designed as regular hexagons, for example.

There is a first clearance S1 between an inner contour 50 of the first transport pocket 20 and an outer contour 51 of the blank 16 or blank ring 46 . Likewise, there is a second play S2 between an inner contour 52 of the second transport pocket 27 and the outer contour 51 of the blank 16 or blank ring 46 before the embossing process. The second game S2 is larger than the first game S1. In the embodiment according to FIG Figures 3 and 4 the respective play S1, S2 results from the difference between the first inner diameter ID1 of the first transport pocket 20 or the second inner diameter ID2 of the second transport pocket 27 and the blank diameter RD (before the embossing process). The blank ring 46 or the blank 16 can move in two dimensions within the first transport bag 20 around the first clearance S1. These two dimensions of the relative movement are oriented at right angles to a blank axis A, around which an edge surface 53 of the blank disk 44 or the blank ring 46 runs ( Figures 7 to 10 ).

Corresponding to this, the second play S2 results from the difference between the inner diameter ID2 of the second transport pocket 27 ( 4 ) and the blank diameter RD. Again, the blank 16 can be in two dimensions perpendicular to the blank axis A according to the second Move game S2 relative to the second transport part 26 or the second turret plate 28 . With the polygonal transport bags 20, 27 and the polygonal outer contour 51 ( Figures 5 and 6 ) the first game S1 and the second game S2 result accordingly. In contrast to the embodiment according to the Figures 3 and 4 However, one cannot speak of a blank diameter and an inner diameter here, but the blank 16 or the blank ring 46 has a blank dimension RA between two opposite sides and the first transport pocket 20 has a first inside dimension IA1 between two opposite sides. Analogous to this, the second transport bag 27 has a second internal dimension IA2.

Other shapes of blanks are also possible due to the transport of the blanks according to the invention. For example, the contour of the hole 45 can deviate from the outer contour 51 . For example, a polygonal hole 45 can have more or fewer corners than a polygonal outer contour 51. It is also possible to design the outer contour 51 without corners, in particular circular, and to design the hole 45 polygonally or vice versa. The radial alignment of the corners of a hole 45 can also deviate from the alignment of the corners of the outer contour 51, so that the two polygonal contours—even if there are the same number of corners—are twisted against one another, so to speak.

As in the Figures 3 to 6 can be seen, the first game S1 is smaller than the second game S2. Preferably, the second clearance S2 is at least 10% or at least 15% larger than the first clearance S1.

The larger second clearance S2 ensures that the embossed coin, the diameter or dimension of which increases as a result of the embossing compared to the blank 16, can be received again in a second transport pocket 27 after the embossing process, in order to be transported further from the embossing station 17 to the removal point 40. In contrast, the first game S1 is significantly less. As a result, the positioning of the blank 16 or the blank ring 46 or the blank disk 44 in a first transport pocket 20 is specified more precisely. This simplifies the preparation of the blank 16 before it is transferred to the second transport part 26 or the second turret wheel 28.

In the exemplary embodiment, the piercing station 44 and the joining station 47 are provided as preparation stations. The first transport part 19 or the first turret wheel 21 is used to transport the blank disks 42 to and from the punching station 44 and/or to transport the blank rings 46 to the joining station 47 and/or to transport the blanks from a blank ring 46 and an inserted core 43 to transport from the joining station 47 to the transfer point 34. The small first play S1 makes it easier to make the hole 45 and to fit the core 43 into the ring 46, since the positioning within the first transport pockets 20 is already very precise.

In 11 is an example and highly schematized a way to provide a blank disk 42 with a hole 45. For example, a punch 56 can be arranged above the punching station 44 in alignment with a first transport pocket 20 . A ram 57 can be arranged below the transport pocket, aligned with the punch 56, which lifts the round disc 42 out of the first transport pocket 20 and against the punch ram 56 pushes. A hole is punched in the round disk 42 . The ram 57 has a recess 58 into which the punch ram 56 engages during the punching process. The punched-out part can also be removed through this recess 58 . A spring-loaded counter-retaining ring 59 can be present around the punching ram 56, which is moved during punching by the ram 57 against the spring force and presses the blank disk 42 or the blank ring 46 against the ram 57. If necessary, the counter-retaining ring 59 can also be used to move the round blank ring 46 back into the first transport pocket 20 .

As in 11 is illustrated schematically, an alignment channel 60 can be present between the first transport pocket 20 and the punch 56 . In the alignment channel 60, the round disk 42 can be brought into a desired rotational position before punching. This is expedient in particular when it is a round disk 42 with a non-round outer contour. For this purpose, for example, the cross-sectional shape of the alignment channel 60 can change, starting from the end associated with the first transport pocket 20 to the end associated with the punch 56 and specifying the rotational position of the circular blank 42 . It can be expedient if the ram 57 simultaneously executes a rotary movement about its own axis during its lifting movement towards the punch 56, whereby the blank disk 42 can also be set in rotation about its blank axis A when it is lifted, so that the rotational alignment within the Alignment channel 60 is simplified or improved by stops present there or other guidance or alignment means.

In 12 a joining device 65 is illustrated, which can be used in a joining station 47. A counter-holder 66 is arranged flush above the first transport pocket 20 in the joining station 47 . Analogously to the punching device 55 according to FIG 11 an alignment channel 60 can be present between the counter-holder 66 and the first transport pocket 20 . The core 43 is fed in below the first transport pocket 20 and positioned above a ram 57 which can lift the core 57 and move it from below against the circular blank ring 46 located in the first transport pocket 20 . As soon as the blank ring 46 rests against the counter-holder 66, the core 43 is pressed in. Optionally, a further alignment channel 60 for the core 43 can be present between the supply of the core 43 and the first transport pocket 20, so that it is oriented in a desired rotational position when it comes into contact with the circular blank ring 46. As with the punching device 55 from 11 the plunger 57 can simultaneously perform a rotary movement about its longitudinal axis during its lifting movement in order to set the core 43 or the ring 46 in a rotary movement until the desired rotary position is reached. This can be advantageous in connection with the alignment channels 60.

The punching device 55 and the joining device 65 according to the 11 and 12 are only examples. Other devices could also be used in the stations 44 and 47 assigned to the first transport part 19 and the first turret wheel 21, respectively. The advantage here is that due to the small first game S1, the position of the blank disk 42 or the blank ring 46 in the first transport pocket 20 can be specified very precisely, so that the preparation of the blank 16 before embossing or before the transfer to the second Transport part 26 or the second Turret wheel 28 is very easy.

Specifically, the illustrated embodiment of the transport device 15 works as follows during the production or minting of a coin:
Blank discs 42 are fed in at the first feed point 41 . In each case one blank disc 42 is inserted into a first transport pocket 20 of the first turret wheel 21 . The first turret wheel 21 is rotated intermittently in stepping motions about the first rotation axis D1. The hole 45 is made in the circular blank 42 in a piercing station 44 so that a ring 46 is formed. This ring 46 is reinserted into the same first transport pocket 20 and transported further out of the perforating station 44 to the joining station 47 are in the first transport bags 20. The two-piece, assembled blank 16 is reinserted into the first transport pocket 20 and transported on from the joining station 47 to the transfer point 34.

At the transfer point 34 the blank 16 is transferred from a first transport pocket 20 into a second transport pocket 27 of the second turret wheel 28 . In this second transport pocket 27, the blank 16 is moved into the embossing station 17 and embossed there to form a coin. Because of the large second clearance S2, there is sufficient space to reinsert the minted coin, which has larger external dimensions than the blank 16, into the second transport pocket 27 and to transport it out of the minting station 17. At a removal point 40, the minted coins removed.

As a modification to the illustrated exemplary embodiments, blanks 16 or blank discs 42 or blank rings 46 with any other outer contour could also be used. It is also possible to provide any other core peripheral contours instead of a circular or polygonal core 43, for example cores 43 with a wavy edge or with an edge that is concave and/or convex in sections. When defining the contours, the coin designer has a great deal of creative freedom.

The invention relates to a transport device 15 and a method for producing a coin using the transport device 15. The transport device 15 is used to transport blanks 16 to an embossing station 17. A drivable first transport part 19 with a plurality of first transport pockets 20 is provided for this purpose. There is a first play S1 between the outer contour 51 of the circular blank 16 and the inner contour 50 of the first transport bag 20 . The transport device 15 also has a second transport part 26 with several second transport pockets 27. Between the outer contour 51 of the blank 16 and the inner contour 52 of the second transport pocket 27 there is a second play S2. The second game S2 is larger than the first game S1. The blanks 16 are transferred from a respective first transport bag 20 into a second transport bag 27 at a transfer point 34 . In the second transport pocket 27, the blanks 16 are transported to the embossing station 17, where a coin is minted from the blank 16. The embossed coin is then transported further from the embossing station 17 in the first transport pocket 27 of the first transport part 26 and to a removal point 40 removed from the first transport part 26.
