Title: System comprising a number of rolls to produce multiple objects from a blank made of metal and/or plastic and a method

Description

The invention relates to a system comprising a number of rolls to produce multiple objects from a blank made of metal and/or plastic.

The invention also relates to a method for producing multiple objects from a blank made of metal and/or plastic. The invention further relates to a computer program product.

In addition, the invention relates to a roll to produce multiple objects from a blank made of metal and/or plastic.

It is an object of the invention to provide a system able to produce objects, such as for example coins or tokens, from a blank made from metal and/or plastic in an efficient manner. It is also an object of the invention to provide a system able to produce non-identical objects.

These objects have been achieved in the system defined in claim 1.

The system uses a number of rolls to produce objects from a blank made of metal and/or plastic. Each object has at least one surface provided with at least an area with a three-dimensional relief, wherein the at least one area is constituted of at least two sub-areas. The rolls comprise at least two distinct relief portions for rolling the blank and each of the at least two distinct relief portions produces one of the at least two sub-areas of the area to be formed on the object. The system further comprises a mechanism for moving the blank and at least one roll with respect to each other such that the area obtained on a first object comprises a different combination of sub-areas than the area obtained on a second object. By means of the mechanism it is possible to make different combinations of sub-areas in each area of different objects by means of the distinct, i.e. non-identical, relief portions of the rolls.

In this way it is possible to produce unique objects, in particular unique coins or unique tokens. It is also possible to use the different areas on each object to track and identify the object.

The distinct relief portions of the rolls for the sub-areas are engraved on at least one roll or on at least two rolls, i.e. a first roll having a first one of the two distinct relief portions and a second roll having the second one of the two distinct relief portions.

The system can be configured as a rolling minting press for coins and tokens which is capable to roll and imprint separately different figures, letters, reliefs, numbers or symbols onto each coin or token, and therefore making the coins different to each other and/or unique. A different combination of sub-areas also includes a different order of the at least two sub-areas of the area. For example, a relief portion configured to provide a first sub-area “A” can be combined with a distinct relief portion providing a second sub-area “B” such that it is possible to produce on a first object an area with the combination “AB” and, after using the mechanism, to produce on a second object an area with the combination “BA”. The combination “AB” is different from the combination “BA”, because the order of the letters has changed.

Each roll may comprise more than one relief portion, and at least a portion of these relief portions on the roll may be identical, i.e. non-distinct. It is further possible that all the relief portions on a single roll are identical, in which case there is another second roll with at least one distinct, i.e. different, relief portion than the relief portions on the first roll.

In the system the rolls will imprint a different part of the area to be formed on the object in successive order, i.e. in different steps in time. For example, a first roll can provide a first sub-area and another roll or the same roll can provide a second sub-area of the area of the object in a second step.

Each relief portion of the at least one rolls is engraved in such a way that its printing or forming surface (for producing a sub-area) only provides a part of the design of the area to be rolled on the object, wherein the other part of the design is engraved and formed by a different relief portion that can be provided on the same roll or on another roll. These engraved relief portions can be distributed along the cylindrical surface of the at least one roll, preferably in a grid pattern. Relief portions (identical and/or distinct relief portions) on at least one roll are situated on a distance with respect to each other on the cylindrical surface of the roll.

If a large quantity of unique objects is desired, the number of distinct relief portions on the roll(s) can be increased. The rolls may comprise at least four distinct relief portions, or at least six distinct relief portions.

The centres of (identical and/or distinct) relief portions on the at least one roll may be connected by a virtual circular line around the circumference of the cylindrical surface of the roll and/or the centres of (identical and/or distinct) relief portions on the at least one roll may be connected by a virtual straight line extending over the circumference of the cylindrical surface of the roll parallel to the centre of the roll. Such a configuration of the relief portions improves the ability for the mechanism to control the movement between the blank and the at least one roll or between the rolls to obtain a maximum number of different combinations of subareas on the objects. However, the relief portions may also be distributed over the cylindrical surface of the roll in a different pattern, such as for example the centres of the relief portion may form a honeycomb pattern.

The sub-area of the area to be rolled on the objects represents partial information such as at least a portion of a figure, of a letter, of a symbol, and/or of a number, wherein the area represents the information comprising a combination of at least two sub-areas. Further, it is possible with the system to produce an area with the three-dimensional relief representing optical variable information which changes when viewing from a different angle.

The roll with at least one relief portion allows to have straight angles between the walls of the rolled relief (forming the sub-area) and the surface of the object, wherein the straight angles of the walls with respect to the surface of the object improve the visibility of the information represented in the area. This is in particular advantageous when the information represents optical variable information.

These individual parts (sub-areas) of the area engraved in the rolls can, for example, display a pre-established sequence, order or relation of symbols or numbers.

As mentioned above, to obtain different combinations of sub areas, the mechanism of the system is used. The mechanism may be configured for moving the at least one roll with respect to another roll and/or the mechanism may be configured for moving the blank with respect to the at least one roll. By moving the at least one roll with respect to the blank or by moving one roll with respect to another roll, it is possible to obtain objects displaying individual combinations of different symbols or numbers once it has passed under each of the different rollers, and the different relief portions, carrying the different symbols or numbers.

Further, the mechanism can be configured for turning the at least one roll with respect to another roll over a predetermined angle around the centre of the roll to provide different combinations of the sub-areas forming the area with the three-dimensional relief and/or the mechanism can be configured to displace the at least one roll in its longitudinal direction with respect to another roll over a predetermined distance to provide different combinations of the sub-areas forming the area with the three-dimensional relief.

Each object has two opposite surfaces and preferably each surface of the two opposite surfaces is to be provided with at least an area with a three-dimensional relief. It is possible that the two opposite surfaces are provided with identical areas or different areas.

Further, it is an object of the invention to provide a method able to produce objects such as coins or tokens from a blank made from metal and/or plastic in an efficient manner. It is also an object of the invention to provide a method able to produce non-identical objects.

These objects have been achieved in the independent method claim and advantageous aspects have been claimed in the dependent claims. The method for producing multiple objects from a blank made of metal and/or plastic, uses rolls to produce the objects and each object to be produced has at least one surface with at least an area with a three-dimensional relief. This area is constituted of at least two sub-areas. The rolls comprise at least two distinct relief portions for rolling the blank and each of the at least two distinct relief portions produces one of the at least two sub-areas of the area to be rolled on the object, wherein the blank and the at least one roll are moved with respect to each other such that the area obtained on a first object comprises a different combination of sub-areas than the area obtained on a second object. In this way it is possible to produce non-identical objects, i.e. at least one area produced on at least one surface of a first object represents different information (different combination sub-areas) than at least one area produced on at least one surface of a second object. In addition, the invention relates to a computer program product, comprising a readable storage medium comprising instructions which, when executed on at least one processor, cause the at least one processor to carry out the method claimed in the method claims.

It is also an object of the invention to provide a roll able to produce objects such as coins or tokens from a blank made from metal and/or plastic in an efficient manner. It is also an object of the invention to provide a roll able to produce non-identical objects. These objects have been achieved in the independent claim claiming a roll and advantageous aspects of such a roll have been claimed in the dependent claims. The roll comprises at least two distinct relief portions and each of the two distinct relief portion produces one of the at least two sub-areas of the area to be rolled on the object. The roll further comprises a mechanism for turning and/or moving the roll such that the area obtained on a first object comprises a different combination of sub-areas than the area obtained on a second object. Non-identical objects as described above can be produced with such a roll. For example, it is possible to produce a first object with such a roll. This first object has at least one surface with an area comprising at least two distinct (non-identical) sub-areas. The first sub-area may for example represent a first symbol and the second sub-area may represent a second symbol. Then, before or during the production of the second object, the roll is turned or moved by means of the mechanism for turning and/or moving the roll with respect to the blank such that at least one area produced on at least one surface of the second object comprises a different combination of sub-areas, i.e. for example the first sub-area represents the second symbol and the second sub-area represents the first symbol. If a large quantity of unique objects is desired, the number of distinct relief portions on the roll can be increased such that it is possible to produce more different (unique) combinations.

The invention will now be explained in more detail with reference to the drawings and by means of a description of an exemplary embodiment of a system, a roll and the objects to be produced therewith, wherein:

Figures 1a,b show a schematic side view respectively a schematic front view of a system with rolls for producing multiple objects from a blank;

Figures 2a-e show details of a roll for producing multiple objects from a blank;

Figure 3 shows a possible combinations of areas to be formed on the objects to be produced with the system;

Figure 4 shows different viewing angles of an object to be produced.

In the following description identical or corresponding parts have identical or corresponding reference numerals.

The purpose of the figures 1a, 1 b is to show schematically a system 1 where two rolls j, j’ are able to rotate and stamp a metal or plastic blank m and to spin or turn the position of the rolls j, j’ with respect to the blank m and/or with respect to each other or with respect to another roll (not shown) depending on the inputs given from a processor (not shown) to the system 1. In other words, the system 1 is electronically controlled by a computer program product, and the rolls are rotated in a pre-determined order by means of a mechanism as will be explained later. The different combinations of sub-areas to be rolled on each object are preferably stored in a database which can be accessed by the computer program product for instructing the processor.

The schematic figures 1a, 1b do not represent the correct proportions, and do not show other possible mechanisms for moving the blank and at least one of the rolls with respect to each other. In particular, other mechanisms (not shown) for moving the rolls with respect to each other or for moving the blank and the roll(s) with respect to each other are possible.

The system 1 comprises a frame A in which the different parts of the system 1 are arranged.

These parts include inter alia a wedge b supported by the frame A. The wedge b controls the pressure of a lower roll j by tightening or untightening the screw b1 which moves an axle d in the directions indicated by arrows P1 and P2. Hence, the wedge b may elevate a block v which then elevates the axle d which is supported by a bearing v1 in block v. The block v has a paddle w which slides up and down inside the groove x provided in the frame A.

The frame A has hole c which allows the axle d to move up and down.

The axle d is attached to a Reuleaux cam e and when this axle d rotates, the cam e transfer its rotary movement to a follower f, resulting in two linear movements: up (arrow P1) and down (arrow P2) and left (arrow P3) to right (arrow P4). These two linear movements allow the follower f to describe (follow) the shape of a square.

The follower f slides along the guide G which has two parts, one is a horizontal guide g1 and the other one is an upright or vertical guide g2. The groove f1 in the follower f allows the follower f to move sideways in the direction of arrows P3 or P4 when the reuleaux cam e rotates and causes the follower to move sideways. The groove i inside the block v allows the vertical part g2 of the guide G to move upside-down when the Reuleaux cam e causes the follower f to move upwards in the direction of P1 or downwards in the direction of P2.

Axles d, d’ pass through frame A and are connected to an external drive mechanism (not shown in drawings). The axles d and d’ are synchronized in their rotations so the dies k or engravings (i.e. the relief portions) on the rolls j, j’ print (roll) on different sides of the blank m at the same time.

The lower roll j is attached to the follower f by holders n 1, n2. The roll j has two shafts j 1, j2 on both sides of the roll j wherein the shafts j 1, j2 are located inside bearings N which are positioned in the holders n 1, n2, allowing the roll j to roll freely. The roll j comprises the engraving or the die k in relief.

The inner shaft j2 of the roll j is attached to a roll axle o which is connected or disconnected from an wheel axle q connected to the centre of a Geneva driven wheel r by a clutch mechanism p.

The clutch mechanism p is in a disengaged position when the follower f is moving upwards towards its upper position and the roll j is coining the blank m. Then, the roll j is rolling. The rolls j, j’ are attached to the followers f, f by holders n 1, n2, n’1, n’2 and the rolls j, j’ are driven (rotated) for coining by the followers f, f moving as a result of the reauleaux cams e, e’, such that when the follower f is in the upper position, the roll j is touching the blank m and when the follower f moves sideways rotates the roll j, which is pressing the plate, and imprint the die k with the engraving. The upper roll j’ does the same.

When the follower f moves downwards and the roll is no longer contacting the metal plate blank m anymore, the clutch mechanism p will be engaged. The clutch mechanism p is then connected and forms a shaft to a Geneva mechanism formed by the Geneva driven wheel r and a drive wheel s which are supported by a support t which is attached to the follower f.

The Geneva drive wheel s has an axle s1 which pass through the support t and is driven by a drive unit (not shown in the drawings). The drive unit turns the drive wheel s depending on the inputs from a processor (not shown) to the system 1. The drive Geneva wheel s turns the Geneva driven wheel r when the follower f is at its most downward position, in which position the roll j is turned by the transmission of the clutch mechanism p.

Once the roll j has been turned over a predetermined angle by means of the Geneva mechanism, the clutch disengage, such that after the blank m is moved another die (not shown) with another engraving (another distinct relief portion) on the roll j is positioned in the correct new position for a new rolling (stamping) step onto the blank m to provide a different sub-area of an area to be rolled on an object to be produced by the system 1 such that an area obtained on a first object comprises a different combination of sub-areas than the area obtained on a second object.

The Geneva mechanism shown in figures 1a,b is an example of a mechanism for moving the blank and at least one roll with respect to each other as defined in the appended claims.

The upper roll mechanism comprising roll j’ is symmetrical to the lower roll mechanism comprising roll j, with the exception that the upper Reuleux cam e’ is attached to an axle d’ passing through the frame and the axle d’ is supported into a bearing y without any possible upside-down movement. Corresponding elements have been identified in the upper frame part with the same reference sign provided with a mark

The main frame A has openings I, I’ in its sides to allow the blank m to pass through the holes and the blank m is displaced by a feeder (not shown in the drawings) after an imprint (coining) is made and the rolls j, j’ are moving from each other. In other words the blank m does not move when the rolls j, j’ are coining. The feeder displaces the blank m in a direction indicated by arrow P5. If there are no other rolls than the rolls j, j’ shown in figures 1a,b than it is possible to displace the blank m in a direction opposite to the direction indicated by arrow P5 such that each roll j, j’ is able to provide the area of the object to be formed comprising at least two sub-areas, i.e. the two sub-areas of one area are formed by rolling the blank m twice with the same roll j, j’, but with different dies k, k’, i.e. two distinct relief portions, to provide two distinct sub-areas of the area to be rolled on the first object. Then, before or during the production of the second object the Geneva mechanism is used to provide a different combination of sub-areas of the area to be rolled on the second object.

The follower f and the follower counterpart f have grooves F, F’ to allow the relief portion k of the rolls to pass through them when the rolls j, j’ rotate.

Blank rollers y1, y’1, y2, y’2 can be provided as guides for carrying and transporting the blank. These rollers y1, y’1, y2, y’2 are not shown in FIG.2.

It is also possible to use a different system to rotate the roll j, j’ with respect to the blank m. Further, it is also possible to use a number of rolls which provide the sub-areas of the area in a stepwise manner, i.e. the first roll j, j’ provides a first sub-area, whereas a second roll (not shown) provides a second sub-area of the area with a three dimensional relief on the object and so on. Then, it is also possible to displace the blank m in a single direction only, for example only in the direction of arrow P5.

Figures 1a,b show a system 1 comprising a roll j and a (counter) roll j’ to produce multiple objects from a blank m made of metal and/or plastic. Each object produced by the rolls j, j’ has two surfaces, wherein each surface is to be provided with at least an area with a three-dimensional relief. At least one roll j comprises at least two distinct relief portions (only a single die k with a relief portion is shown in the drawings) and one of the at least two distinct relief portions provides a sub-area of the area to be rolled on the object. The system 1 further comprises the Geneva mechanism for moving the blank m and the at least one roll j with respect to each other such that it is possible to produce a first object with a surface having at least a first area and to produce a second object with a surface having at least a second area comprising a different combination of sub-areas than the first area.

The relief portions on each roll j, j’ are provided by dies k, k’, wherein at least one other relief portion (not shown) is provided on the other side of each roll.

It is also possible that one of the rolls j, j’ is provided with a flat die (not shown) such that one side of the object does not receive an imprinted area with a three-dimensional relief, and only one side of the object to be produced has an imprinted area with a three-dimensional relief. Further, it is possible that the object is rolled on one side with non-distinct relief portions of the rolls j, j’ and the other side of the object is rolled with at least two distinct relief portions of the rolls j, j’.

Figures 2a and 2c show a top view and a cross section of the first roll 10 carrying a first relief portion 1.1 of the engraving or die 11. This first relief portion 1.1 is in relief with respect to the cylindrical surface 12 of the roll 10, i.e. the first relief portion 1.1 is located further from the centre of the roll 10 than the cylindrical surface 12.

The die 11 has further an indentation 1.2, 1.2’ forming a rim around the first relief portion 1.1, wherein the indentation 1.2 is located below the surface 12 of the roll 10 (closer to the centre of the roll 10) to absorb the material of the blank g (figure 2c), for example a metal plate, displaced by the pressure of the first relief portion 1.1 forming the first sub-area 15 on the object to be produced.

The portion 1.6 corresponds to a sub-area 16 of the object, for example a coin, which is not going to be rolled in the first step. Hence, the portion 1.6 does not have any engraving/relief and this portion 1.6 is flush with the surface 12 the roll 10. It is also possible to raise this portion 1.6 minimally with respect to the surface 12, such that a pre-shape for the next rolling step (not shown in the drawings) can be obtained.

The die 11 on the roll 10 has a rim 1.3 in relief encircling the above mentioned first relief portion 1.1, the indentation 1.2, 1.2’, and the portion 1,6.

The rim 1.3 in relief is an edge with a slope or draft 1.4. This rim 1.3 can be used to cut the object, i.e. coin, out from the metal strip g in different subsequent steps, by increasing the height of the rim 1.3 with respect to the surface 12 of the roll 10 in each subsequent roll used for rolling the object. The rim 1.3 and the slope 1.4 provide a beginning (hole with a first depth) 17 of the outer circumference of the coin to be produced

The roll 10 further has shafts 1.5 on both sides to be attached to a holder (not shown). The roll 10 may be driven as explained in the example shown in figure 1a,b, but it is also possible that the rolls can be driven (rotated) in a different manner.

Figure 2c also shows a counter roll 10’ which is provided with an identical die as the die 11 of the roll 10, i.e. the die of the counter roll 10’ comprises a first relief portion, the indentation 1.2, 1.2’, the rim 1.3 with the slope 1.4 and the portion 1.6. The roll’s 10, 10’ are aligned such that in use the metal strip g is stamped on opposite sides simultaneously with the dies 11 of the rolls 10, 10’.

In use the roll 10 and the counter roll 10’ roll the metal strip g to produce a coin with two opposite surfaces to be provided with the same area with a three-dimensional relief, wherein the roll 10 and the counter roll 10’ provide the first sub-area 15 of that area.

Figures 2b and 2d show a top view and a cross section of a second roll 20 with a second die 21 with a second relief portion 2.1 for providing a second sub-area 25 on the coin aside the first sub-area 15 provided by the die 11 of the roll 10. The second relief portion 2.1 is distinct (not shown) from the first relief portion 1.1.

The portion 2.6 is identical to portion 1.6 and corresponds to a sub-area of the object for example a coin which is not going to be imprinted with the roll 20, 20’. Hence, the portion 2.6 does also not have any engraving/relief and this portion 2.6 is flush with the surface 22 of the roll 20.

The second relief portion 2.1 is also encircled by an indentation 2.2, 2.2’ in the surface 22 of the roll 20. A rim 2.3 in relief is provided around the second relief portion 2.1, the portion 2.6. and the indentation 2.4, 2.4’.

The rim 2.3 has a greater height measured from the surface 22 of the roll 20 than the height of the rim 1.3 measured from the surface 12 of the first roll 10. Hence, the rim 2.3 will deepen the beginning 17 to produce a deeper hole 27 and therefore further reduce the thickness of the metal strip 9, so it will help and reduce the pressure needed in a later cutting of the coin from the metal strip g. By means of the rims 1.3, 2.3 provided on the dies 11, 21 it is possible to reduce the wear of cutting tools (not shown).

Figure 2d shows a cross section of the second rolls 20, 20’ and the metal stripe g showing both impressions 15; 25, the one from the first rolls 10, 10’ and the one from the second rolls 20, 20’. Hence, after the rolls 20, 20’ have rolled the metal strip g the second sub-area 25 is formed and the area of the object/coin is produced. In this example shown two identical areas on opposite surfaces of the object/coin.

The rolls 10, 10’, 20, 20’ shown in figures 2a-2e only show rolls 10, 10’, 20, 20’ having a single die 11, 21 with a single relief portion 1.1,2.1. These rolls 10, 10’ in combination with rolls 20, 20’ are able to provide two distinct relief portions 1.1, 2.1.

The rolls 10, 10’, 20, 20’ of the system may have more than one relief portion, wherein the relief portions on a single roll may be identical or distinct. Further, it is possible that each roll comprises at least two distinct relief portions or more such as at least four or at least six distinct relief portions.

Figure 3 shows a matrix of fifteen possible combinations when one of the rolls R1, R2 are rotated by a mechanism (for example by the mechanism shown in figures 1a,b) over a predetermined angle with respect to another roll R1, R2.

The first roll R1 and the second roll R2 comprise different dies with different relief portions, for example each roll R1, R2 has five different dies with relief portions for providing the letters “a”, “b”, “c”, “d”, and ”e” on an object to be rolled.

When the rolls R1, R2 roll side by side, it will make the coins 1 to 5, and these coins carry the same letter side to side, i.e. roll R1 provides sub-area with the letter “a” on the first coin and roll R2 provides sub-area with the letter “a” on the first coin to obtain five different combinations (“bb”, “cc”, “dd” and “ee”) on five coins 1 to 5.

In the second column of the matrix, R2 has been rotated over a predetermined angle of for example 72 degrees by the electronic input of the machine, such that different combinations of letters are obtainable. Hence, rolling the rolls R1, R2 side by side in a second run will provide the coins shown in the second column, of which the first coin (6) displays the area of the coin with the combination “a” and “b”.

In the third column, R2 has been rotated again over the same predetermined angle which results in the combination of sub-areas in the area of the coins as shown.

The rolls R1, R2 can be rotated until all possible combinations have been used.

Instead of turning roll R2 with respect to roll R1 after rolling five subareas, it is also possible that the system turns the roll R2 with respect to roll R1 or vice versa after rolling a single sub-area with each roll R1, R2 such that the system produces the coins with a different combination of sub-area in a random order. Each sub-area represents a letter in the embodiment shown in figure 3 and a area is a combination of two letters in this example.

Instead of using a mechanism configured for turning the at least one roll R2 with respect to another roll R1 over a predetermined angle around the centre of the roll to provide different combinations of the sub-areas forming the area with the three-dimensional relief, it is also possible to use a mechanism configured to displace the at least one roll in its longitudinal direction with respect to another roll over a predetermined distance to provide different combinations of the sub-areas forming the area with the three-dimensional relief.

The centres of the relief portions (producing the letters shown in figure 3) on the rolls R1, R2 are preferably connected by a virtual circular line around the circumference of the cylindrical surface of the roll R1, R2 and/or the centres of the relief portions (producing the letters shown in figure 3) on the rolls R1, R2 are connected by a virtual straight line extending over the circumference of the cylindrical surface of the roll parallel to the centre (rotation axis) of the roll R1, R2. In this way, the mechanism for providing different combinations of sub-areas can be controlled.

The sub-area may also represent different (partial) information than a letter such as at least a portion of a figure, at least a portion of a symbol, and/or at least a portion of a number, wherein the area represents the information comprising a combination of at least two sub-areas.

In order to increase the possible combinations, the engraving in relief can carry an optical variable device which is able to display information which is shown when the coin is viewed from different angles. This information can be set up as an optical variable device (3d multi view). The design on the coin is the mirror image in the roll or vice versa.

Figure 4 shows how a coin 100 constructed as an optical variable device can be tilted and the edges of the pattern shining in different angles. The coin 100 comprises four areas. Each area is provided by using the system 1 shown in figures 1a,b and/or the rolls 10, 20 shown in figure 2a-e, wherein the dies to be used are configured for rolling the areas of the optical variable device.

It is also important the system using rolls can provide images with a relatively low relief. This is advantageous because less pressure will be needed to mint the coin which also results in less distortion of the design to be provided on the coin.

In the system the objects such as for example coins can have any shape.
