Definitions

  • the invention relates to a method for processing a substrate with a punch and a processing tool for processing a substrate.
  • Documents such as value or security documents are usually made up of one or more substrate layers.
  • the selection of the materials used here and the special structure, in particular of multi-layer documents, is often made in such a way that subsequent copying or falsification of the document is made considerably more difficult.
  • One way of increasing the counterfeit security of a document is that individual or multiple substrate layers are not made of the same material over the entire area, but at least in sections different materials are used. For example, it is possible for a document to have a transparent window.
  • the DE 10 2014 000 133 B4 discloses a method for processing a flat, at least single-layer substrate, in that the substrate is guided through a processing tool together with a film material on different levels and a punch produces an opening at a predetermined point in the substrate.
  • the punch is then moved to an area outside the opening and in a further stroke of a filling material, an element corresponding to the cross-section of the opening is punched out by the punch, then moved by the punch in the direction of the opening of the fixed substrate and the element through the punch inserted into the opening of the substrate.
  • the object of the invention is to provide a method for processing a substrate and a corresponding processing tool for processing a substrate.
  • a substrate is generally understood to be a single-layer layer made from one material or a multi-layer layer made from one or more materials, with paper, cardboard or plastic and also metal foils being able to be used as the material.
  • the substrate can generally be the carrier material of a valuable or security document or at least one layer of the carrier material of a valuable or security document.
  • the carrier material can in turn be a card body, for example, if the value or security document is a card-shaped document.
  • a document is generally understood to mean paper-based and/or plastic-based documents, such as ID documents, in particular passports, identity cards, visas and driving licenses, vehicle registration documents, vehicle registration documents, company ID cards, health cards or other ID documents as well as chip cards, means of payment, in particular bank cards and Credit cards, bills of lading or other proof of entitlement. Documents of value can also be banknotes in particular.
  • Embodiments of the invention could have the advantage that with a mechanically simple tool structure, which is therefore less error-prone during use, of the machining tool used to carry out the method a filling element can be inserted into a substrate with high precision.
  • the filling material used for this purpose can in turn have a single-layer or multi-layer structure and consist of different layers of material and can also be based on paper, cardboard, metal or plastic.
  • substrate and filling material are not arranged one above the other, but next to one another. This could eliminate the need for moving anvil strips, for example.
  • a further advantage could be that the first and second punching positions can be selected flexibly parallel to the plane. So instead of, as in the prior art DE 10 2014 000 133 B4 described to process the substrate and filling material at exactly predefined points with the punch, the method described could make it possible to flexibly and even individually define the respective punching positions for each substrate and/or filling material.
  • the punching out of the opening results in a substrate element that corresponds to the cross section of the opening, the substrate element being removed from the punch before the filling element is punched out.
  • a ram could be used here, which pushes the substrate element located therein downward through the punch through the punch.
  • the punch is preferably located above a corresponding container for receiving the substrate element that results as a waste product.
  • the punch is subjected to ultrasound when the opening is punched out and/or when the desired filling material is punched out.
  • the application of ultrasound could cause an ultrasound-induced softening of the material to be punched out, so that the force required by the punch for the actual punching out is reduced.
  • a material that has been softened by the ultrasound is punched out due to the impact of the ultrasound.
  • This could mean that the performance requirements of the robot guiding the punch can be reduced in terms of the forces to be applied.
  • This could, for example, enable the punch to be guided by a robot that does not have to have extreme requirements in terms of force and high precision.
  • a relatively simple robot could therefore be used, the only main requirement of which is high precision, since the forces to be applied by the robot via the punch could be reduced due to the application of ultrasound.
  • the part of the substrate extending in the plane is supported by a stationary stop in the direction perpendicular to the plane.
  • a stationary stop in the direction perpendicular to the plane.
  • the substrate element is therefore not removed as in the prior art DE 10 2014 000 133 B4 described through the opening produced in the substrate, but here there is almost any freedom as to the punching position at which the removal of the substrate element has to take place. This could also change the geometric structure of the device used to carry out the method, in particular with regard to the removal of the substrate elements as a waste product.
  • the punch has an outer cutting surface, the punching angle of the cutting surface being less than 90°.
  • this could be realized by moving different elements of the punch. In the case of a rectangular punch, this would require four movable elements which carry out the punching process individually at a punching angle of ⁇ 90°.
  • a trapezoidal punching could be made possible, which, due to the trapezoidal shape and with regard to the filling element to be inserted into the opening, limits the possible degrees of freedom of the filling element in the opening to a single degree of freedom. Due to the trapezoidal shape, the filling material is held in the opening both laterally and downwards.
  • the punch touches the edge of the opening of the substrate.
  • the punch is subjected to ultrasound.
  • the edge of the opening softens, e.g. is plasticized, when the filling element is inserted.
  • the edge softened in this way can now enter into a preferably materially bonded connection with the filling element when the punch is withdrawn. In this way, the filling element could not only be mechanically “clamped” in the punched-out opening, but could even be welded into the opening.
  • the substrate is held by a processing tool when the opening is punched out and the filling element is inserted, the relative movement taking place when the punch is transferred between the first punching position and the second punching position by moving the punch relative to the machining tool.
  • the machining tool could therefore be designed to be rigid and the punch could be moved along the machining tool, for example by a robot.
  • the punch is arranged on an arm, the movement of the punch comprising rotating the arm about an axis of the machining tool extending perpendicular to the plane.
  • This could also simplify the mechanical structure of the device used to carry out the method, so that a corresponding device could be produced in a cost-effective manner: it would have to be ensured, for example, that the arm can be rotated about an axis, in addition in the direction perpendicular to the plane mobility of the punch either together with the arm or relative to the arm would be necessary.
  • this could also be implemented with a robot arm that can be moved as desired in all three dimensions and a punching die located thereon, it is at significantly higher costs and possibly with less precision in carrying out the method.
  • a first magazine has a set of filling materials, the filling materials of the set of filling materials being arranged in series in the first magazine, the method further comprising, before punching out the filling element, moving the first magazine so that the desired filling material Seen in the direction of the plane comes to rest in the second punching position.
  • the first magazine comprises a first turntable, the filling materials of the set of filling materials being arranged in a circle one behind the other on the first turntable, the movement of the magazine comprising rotating the first turntable.
  • the use of the magazine with the filling materials arranged one behind the other in it could have the advantage that a flexible availability of filling materials can be guaranteed with the same mobility and movement of the punch. Especially with regard to Industry 4.0 and the associated need for flexibility, this could require, for example, the substrate-specific or document-specific filling materials are to be used.
  • the individual filling materials of the set of filling materials can be arranged one behind the other on a carriage, so that the carriage only has to be moved along a linear path into the appropriate second punching position, so that the desired filling material can be fed in the direction of the Seen level comes to rest in the second punching position.
  • a second magazine can have a set of substrates, the substrates of the set of substrates being arranged one behind the other in the second magazine and the substrate comprising an opening to be punched out, the method further comprising moving the opening before the opening is punched out second magazine in such a way that the substrate with the opening to be punched out does not come to lie in the first punching position, seen in the plane.
  • the second magazine can comprise a second turntable, the substrate and the set of substrates being arranged in a circle one behind the other on the second turntable and the movement of the magazine comprising rotating the second turntable.
  • the substrates could be positioned in the second magazine at a punching position that differs from the first punching position.
  • laminated or partially laminated substrates provided in a prepared work step could be prefixed in a suitable manner in the second magazine in a punching position that differs from the first punching position.
  • the substrate pre-fixed in this way is then conveyed to the first punching position in order to then be subjected to the method described above.
  • the removal of the substrate processed in this way for inserting the filling element into the opening produced could take place by conveying the processed substrate further into a further punching position, preferably different from the first punching position.
  • the onward conveyance means that a substrate which has subsequently been made available in the meantime is automatically conveyed back into the first punching position. In this way, a supply of substrates and a removal of processed substrates could be ensured in a mechanically simple and space-saving manner.
  • the substrate is the carrier material, for example the card body, of a valuable or security document or at least one layer of a carrier material of a valuable or security document.
  • the filling material is transparent and the substrate element is opaque in the wavelength range of visible light.
  • transparent is understood to mean a transmission t>0.7 and an opaque material is understood to mean a transmission t ⁇ 0.1.
  • the figure 1 shows a schematic view of a security document, for example an identity card.
  • the badge has a body which is referred to as substrate 100 hereinafter.
  • the ID card In addition to various security features and identification features such as a photo of the owner of the ID card and his name and address, the ID card also has an element 102, e.g. a transparent window 102. It is both possible that the transparent window 102 is only provided as a purely transparent window in the ID card or it is also possible that the transparent window itself carries various security features. It is possible, for example, that when looking through the transparent window, structures contained in the window become visible, which are intended to ensure that the ID card is protected against forgery. In addition to directly visible structures, the transparent window 102 can also have various microstructures which only reveal corresponding defined information by projecting laser light shining through the window onto a surface.
  • the substrate 100 is the substrate, ie the card body or a part of a card body of an ID card, and that the element 102 is a transparent see-through window.
  • the substrate 100 can represent any carrier material of a valuable or security document or a layer of the carrier material of a valuable or security document.
  • the element 102 can be any type of filling element, which, however, preferably represents a specific security feature of the valuable or security document. A corresponding transparency of the filling element 102 is not absolutely necessary.
  • the substrate 100 extends in one plane.
  • this plane is a horizontal plane.
  • “Extend in the plane” is generally understood in the context of the entire description to mean that in the case of a three-dimensional body, the largest extension and expansion of the body in terms of surface area lies in the said plane.
  • Said level is in the figure 2 indicated by the reference numeral 206 and extends in the horizontal direction.
  • the punch 204 reciprocates toward the substrate 100 and punches an opening in the in-plane portion of the substrate.
  • the punch 204 is seen in the direction of the plane 206 in a first punching position.
  • the result of the punching process is in the Figure 2b 1, where the punched opening 208 in the substrate 100 can now be seen.
  • the substrate element 200 still located in the punch 204 due to the punching process is now removed from the punch 204 in the next step.
  • a ram 201 be used, which pushes the substrate element 200 still located in the punch downwards through the punch.
  • the punch 204 is then moved further parallel to the plane 206 to a second punching position.
  • the substrate element is therefore ejected at a punching position of the punch which differs from the first punching position and the second punching position of the punch.
  • the filling material and the substrate extend along a common plane 206, this is not absolutely necessary to implement the method described. It is also possible for the substrate and filling material to be on different, preferably parallel planes. They should, however, be positioned spatially next to each other as seen with respect to the plane 206 and not one above the other or overlapping.
  • the filling element 102 Due to the punching process of the filling element, the filling element 102 is located in the punch 204. In this state, the punch 204 is moved from the second punching position (to the figures 2 the right punching position) back to the first punching position (left punching position). The punched-out filling element 102 leaves an opening 210 in the filling material 202, but this is not relevant to the present description ( Figure 2d ).
  • the punch 204 is subjected to ultrasound in such a way that the substrate touched by the punch or the filling material softens. Because the punch is subjected to ultrasound, when the punch touches the substrate or the filling material, ultrasonic energy is transmitted to the substrate or the filling material, so that the contact area between the punch and the substrate or the filling material is heated and the material touched by the punch is softened .
  • a first advantage could be that due to the lower required punching force, the tool part required to guide the punching die also only has to be mechanically designed for the correspondingly lower force input. Therefore, a robot in particular could be used for guiding the punching die, which has a high positioning accuracy but a reduced ability to apply the required punching force. This results in the possibility of choosing correspondingly more cost-effective robots.
  • a second advantage could be that due to the reduced forces that prevail, the compression of the material to be punched that results during the punching process is also reduced. A corresponding punching process could thus deliver significantly more precise punching results than would be possible with direct processing of the material in the hard state.
  • a further advantage could be that a reduction in mechanical tool wear is possible, resulting in a better service life of the punching tool.
  • the aim of the method is to reinsert the punched-out filling element into the opening of the substrate, a precise punching result is particularly useful here both for the substrate opening and for the filling element.
  • the figure 3 shows a schematic plan view of a processing tool for processing the substrate 100.
  • the punch 204 which is arranged on an arm 302, is used again.
  • the arm can be pivoted about an axis 310 so that the punch 204 can be moved from its in figure 3 left first punching position in the right second punching position (shown in phantom) is pivotable.
  • the left punching position corresponds to the figure 2 that punching position of the punch 204 in which both the opening 208 can be punched and the filling element 102 is inserted into the substrate 100.
  • the right-hand punching position of the punch 204 in FIG figure 3 that punching position in the figure 2 , in which the punch punches out the filling element from the filling material.
  • FIG 3 different substrates 100 are now arranged in a circle one behind the other on a turntable.
  • the turntable 301 can be rotated as desired in a direction of rotation 304, so that the desired substrate 100 of the set of substrates located on the turntable 301 comes to rest in the first punching position. It is conceivable, for example, that the turntable 301 can rotate clockwise.
  • a substrate located in the 1 o'clock position can be subjected to the punching process, whereas a substrate located in the 3 o'clock position with inserted filling element can be removed there and fed to further processing, for example lamination or personalization.
  • a substrate blank can be fed to the turntable 301 at the 5 o'clock position.
  • a turntable 303 for various filling materials arranged in a circle on the turntable 303 one behind the other.
  • This turntable can also be rotated as desired about an axis (direction of rotation 306), for example again clockwise here.
  • Those skilled in the art will be able to transfer the principle explained with regard to the turntable 301 to the turntable 303 and the filling materials 202 located there.
  • the 1 o'clock position would be the removal position of the filling material subjected to the stamping process and the 3 o'clock position would be the feeding position at which new filling material can be fed to the turntable 303 .
  • a rigid arm 302 which can be rotated about an axis 310
  • a three-dimensionally movable robot which guides the punch 204 is used.
  • the arm 302 it is possible, for example, for the arm 302 to also be movable in the direction in which the arm extends, so that any desired punching position on the substrate 100 or the filling material 202 can be approached before the punching process in connection with the rotation about the axis 310 .
  • this can also be controlled individually for each substrate, so that the flexibility required with regard to Industry 4.0 is guaranteed when processing any substrates and filling materials.
  • the filling materials 202 on the turntable 303 it should also be noted that it is possible for the filling materials 202 on the turntable 303 to have partially different material compositions or different security features. It is also possible here to punch out the desired substrate element from the filling material rotated to the right-hand punching position and insert it into the opening previously created in the substrate by rotating the turntable 303 accordingly. It could be of great use here if the punch is fully movable in all directions, since then with one and the same filling material (e.g. a sheet of material) it is possible to punch out the filling elements at different points and thus a given filling material (a given sheet of filling material) used several times and can be used correspondingly often.
  • a given filling material a given sheet of filling material
  • the figure 4 12 shows a variant in which, in the simplest form, the arm 302 is rigid and in particular immobile with respect to the axis 310.
  • FIG. In order to nevertheless realize the first and second punching position, substrate 100 and filling material 202 are located on a turntable 400 and are thus brought into the corresponding punching position by any rotation in direction 402, seen from the perspective of the substrate or filling material. In the position of the turntable 400 shown in the figure, the process of punching the opening in the substrate 100 and inserting the filling element into the opening can thus take place, whereas punching out the filling element requires that the filling material 202 be rotated to the punching position in which the figure 4 currently the substrate 100 is located.
  • the arm 302 could again be able to move both in the direction of extension of the arm, i.e. in the radial direction to the axis 310, as well as a mobility of the arm in any direction 300, i.e. a rotation of the arm around the axis 310 can be helpful.
  • the punching positions are limited to a relatively small area within the substrate, the mobility of the punch required for this purpose is limited to just that area and a corresponding robot guidance of the punch can be restricted to precisely this area. This could significantly simplify the mechanical structure of the robot used for this purpose.
  • a robot is generally understood to mean a device which is able to bring the punch into a desired punching position. This can be a robot in the conventional sense, which may have a number of different joints around which corresponding robot arms are pivoted or rotated to position the punch.
  • a robot is also understood to mean a device such as that described above with regard to figure 3 and the figure 4 with an axis of rotation 310 and an arm 302.
  • the figure 5 shows a cross-sectional view through a substrate 100 with a trapezoidal opening 208.
  • the filling element 102 has a trapezoidal shape with a sloping edge 500.
  • the punching angle ⁇ the cutting surface is less than 90°.
  • the case of a rectangular cross-section of opening or substrate or filling element seen in plane 206 could be realized by four punching cutters, which carry out the punching process at said angle ⁇ on the four edges of this rectangle. The punching blades thus cut into the substrate or the filling material at an angle ⁇ in order to punch out and obtain trapezoidal openings or the corresponding trapezoidal filling element.
  • a trapezoidal shape for example, or generally a cut surface ⁇ 90° would be advantageous in that after inserting the filling element 302 into the opening 208, the degrees of freedom of movement of the filling element 102 are restricted to only one direction opposite to the direction of insertion. This could increase the mechanical stability with which the filling element is held in the substrate.
  • the edge of the opening 208 and the filling element 102 are touched by the ultrasonic punch of the stamping die, which is acted upon by ultrasound Material connection after inserting the filling element 102 into the substrate 100 is made possible. This further increases the force with which the filling element 102 is fixed in the substrate 100 .
