Definitions

  • the invention relates to a method for processing a substrate with a punch and a machining tool for processing a substrate.
  • Documents such as value or security documents are usually constructed from one or more substrate layers.
  • the choice of the materials used in this case and the special structure, in particular of multilayer documents, is frequently such that a subsequent copy or forgery of the document is made considerably more difficult.
  • One possibility for increasing the security against forgery of a document is that individual or multiple substrate layers do not consist of the same material in a planar manner, but that at least in sections different materials are used. For example, it is possible for a document to have a transparent window.
  • DE 10 2014 000 133 B4 discloses a method for processing a planar, at least single-layered substrate by passing the substrate through a processing tool together with a film material at different levels and by producing a punch at a predetermined location of the substrate. The punch is then moved in an area outside the opening and in a further stroke of a filling material is stamped by the punch a cross-section of the opening corresponding element, 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 invention has for its object to provide a method for processing a substrate and a corresponding processing tool for processing a substrate.
  • the punch again performing a relative movement of the punch and the substrate in a direction parallel to the plane, the punch, as a result of the relative movement in the direction of the plane, being located above the opening of the substrate in the first punching position,
  • a substrate is generally understood to be a single-layer layer of a material or a multilayer layer of one or more materials, it being possible to use paper, cardboard or plastic as well as metal foils as the material.
  • the substrate may generally be the substrate of a value or security document or at least one layer of the substrate of a value or security document.
  • the carrier material may in turn be, for example, a card body, if the security document is a card-shaped document.
  • a document Under a document are generally paper-based and / or plastic-based documents understood, such as identity documents, in particular passports, identity cards, visas and driving licenses, vehicle registration documents, vehicle registration documents, company cards, health cards or other ID documents, as well as smart cards, means of payment, especially bank cards and Credit cards, bills of lading or other credentials. Value documents can also be bills in particular.
  • Embodiments of the invention could have the advantage that, with a mechanically simple and thus, in the case of use, error-prone tool construction of the machining mechanism used for carrying out the method. With high precision, a filling element can be inserted into a substrate.
  • the filling material used for this purpose can in turn be constructed in one or more layers and in this case consist of different material layers and likewise be paper-, cardboard-, metal- or plastic-based.
  • the substrate and filling material are not arranged one above the other but next to one another. This could, for example, eliminate the need to use movable anvil strips. Another advantage could be that a flexible selectability of the first and second punching position is parallel to the plane.
  • a substrate element corresponding to the cross section of the opening results, the substrate element being removed from the punching punch before the filling element is punched out.
  • a ram could be used here, which pushes the substrate element located therein through the punch through downwards through the punch.
  • the punch is preferably located above a corresponding receptacle for receiving the substrate element resulting as a waste product.
  • the punch is subjected to the punching of the opening and / or the punching of the desired filling material with ultrasound.
  • the ultrasound application 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. So instead of punching out a hard material, a material softened by the ultrasound is punched out due to the application of ultrasound.
  • the requirements for the performance of the punching robot can be reduced with regard to the forces to be applied. This could, for example, allow the punch to be guided by a robot that does not have to impose extreme demands on efficiency and high precision. It could thus be used a relatively simple robot, which only has a high precision as the main requirement, since the forces to be applied by the robot on the punch could be reduced due to the ultrasound.

  • the in-plane portion of the substrate is supported by a stationary stop in the direction perpendicular to the plane.
  • a stationary stop in the direction perpendicular to the plane.
  • the punch has an outer cut surface, wherein the punch angle of the cut surface is smaller than 90 °.
  • this could be realized by moving various elements of the punch. In the case of a rectangular punch, this would require four movable elements, which individually perform the punching operation in a punching angle ⁇ 90 °.
  • a trapezoidal cut could be made possible which limits the possible degrees of freedom of the filling element in the opening to a single degree of freedom due to the trapezoidal shape and with respect to the filling element to be inserted into the opening. Both side and down the filler material is held in the opening due to the trapezoidal shape.
  • the punch touched when inserting the filling element of the punch the edge of the opening of the substrate.
  • the punch is subjected to ultrasound.
  • This could have the advantage that, in particular in the case of plastic substrates, when the filling element is inserted, the edge of the opening is softened, e.g. is plasticized. The thus softened edge can now enter into a preferably cohesive composite with the filler when retracting the punch.
  • the filling element in the punched-out opening could not only be mechanically “clamped", but even be welded into the opening.
  • the substrate is held during the punching of the opening and insertion of the filling element by a machining tool, wherein the relative movement with the transfer of the punch between the first punching position and the second punching position by a method of the punch stem is relative to the processing tool.
  • the machining tool could therefore be designed to be rigid and the punch could, for example, be moved along by a robot on the machining tool.
  • the punch is arranged on an arm, wherein the method of the punch comprises a rotation of the arm about an axis of the machining tool extending perpendicular to the plane. This, too, could simplify the mechanical construction of the device used for carrying out the method, so that a corresponding device could be produced in a cost-effective manner.
  • a first magazine comprises a set of filling materials, wherein the filling materials of the set of filling materials are arranged one behind the other in the first magazine, the method further comprising moving the first magazine so that the desired filling material prior to punching out the filling element seen in the direction of the plane to lie in the second punched position.

  • flexible availability of filling materials can be ensured.
  • stratindividuell or document-individual filler materials are used.
  • the individual filling materials of the set of filling materials are arranged on a carriage one behind the other, so that the carriage must be moved along a linear path only in the appropriate second punching position, so that the desired filling material in the direction of Level seen in the second punching position comes to rest.
  • a second magazine may comprise a set of substrates, wherein the substrates of the set of substrates are arranged in the second magazine one behind the other and the substrate comprises an opening to be punched out, the method also entering before punching out the opening Moving the second magazine so includes that the substrate with the punched-out opening does not come to lie in the first punching position as seen in the plane.
