  • the distance between the punching punches/perforating needles is relatively large due to the chosen geometry, so that punching/perforation patterns with a small grid dimension cannot be produced.

Furthermore, there is a first pressure accumulator 28.1 and a second pressure accumulator 32.1, which communicate with the valve device 26.
  • the first pressure chamber 28 provides a pressure P1
  • the second pressure chamber 32 provides a pressure P2 that is greater than the pressure P1.
  • Each perforating needle 16 is assigned a locking slide 22 with an associated controllable piston-cylinder unit.
  • the locking slide 22 is spaced from the upper head end of the perforating needle 16.
  • Below the locking slide 22 is an extension profile 48 in the control block 14 in a corresponding guide, the extension profile 48 resting on the underside of the head of the associated perforating needle 16 and the upper end face of the extension profile 48 is arranged at the height level of the underside of the locking slide 22. In the extended state of the locking slide 22, it rests on the extension profile 48, so that when the lifting movement H of the control block 14 is carried out, the perforating needle 16 is moved downwards and triggers a perforation on the material unit/web M.
  • the locking slide 22 has in its free end region a contour 52 which is inclined against the punching/perforation stroke direction H, which ensures that if the extension profile 48 or the perforating needle 16 has a protrusion upwards when the locking slide 22 is extended, the extension profile 48 protrudes downwards pushed and not sheared off or damaged. This ensures long-term, reliable functionality.
  • the first pressure chamber 28 and second pressure chamber 32 are individually controlled as follows via the valve device 26 and the control device 30, taking into account the stored punching/perforation pattern data.
  • the first pressure chamber 28 is permanently pressurized with the pressure P1 via the first pressure accumulator 28.1, that is, under the effect of the pressure P1, the locking slide 22 is in the retracted position Position so that when the punching/perforation stroke H is carried out, the associated perforating needle 16 does not perform any perforation.
  • the control device 30 causes, via the valve device 26, that the second pressure chamber 32 is pressurized via the second pressure accumulator 32.1 with the pressure P2, which is greater than the permanently existing pressure P1 in the first pressure chamber 28, so that the locking slide 22 extends and when the punching/perforation stroke H is carried out, the associated perforating needle 16 in conjunction with the extension profile 48 carries out a punching/perforation stroke H and produces a perforation on the material unit/web M.
  • Piston-cylinder units are therefore individually controlled on the control block 14 and are under a permanent first pressure P1, which essentially forms an air spring in the return stroke, with a piston rod 20 of the corresponding piston-cylinder unit for each perforating needle 16 to be controlled in the punching/perforating tool 12 is assigned, which is activated, that is extended, by applying the pressure P2.
  • the extension profile 48 is arranged between the head of the individual perforating needles 16 and the locking slide 22.
  • the extension profile 48 consists, for example, of a hardened round material with a reduced diameter, which rests loosely on the head of the perforating needle 16.
  • the offset outer diameter prevents movement of the vertically installed extension profile 48 in the control block 14 when the tool is removed.
  • the extension profile 48 is held in a fixed, defined position above the needle head by this shoulder.
  • these mechanical extension profiles 48 are used in different lengths in the control block 14 and assigned to the locking slides 22 accordingly.
  • the individual piston-cylinder units are present as special cylinders on both sides of the control block 14 and are individually controlled by control valves 26.
  • These special cylinders are arranged within the machine, for example in housings 38, each with four piston-cylinder units, to protect them from damage or access.
  • These housings 38 contain the complete electronic and pneumatic control (valve islands, pressure regulators, pressure monitoring, etc.).

    - le dispositif de commande (30) se trouve en communication avec le dispositif de mémoire (40),
    - le dispositif de commande (30) se trouve en liaison active avec un bloc de commande (14) des poinçons/aiguilles de perforation (16) afin de commander/activer/désactiver les poinçons/aiguilles de perforation (16) lors de l'opération de poinçonnage/perforation,
    - le dispositif de commande (30) se trouve en liaison de communication avec les moyens (70, 72) afin de générer un mouvement relatif simultané de l'unité/bande de matériau (M) et
    - le dispositif de commande (30) ordonne l'activation correspondante des moyens (70, 72) en fonction des données enregistrées dans le dispositif de mémoire (40).
  6. Machine de poinçonnage/perforation selon l'une des revendications précédentes,
    - caractérisée en ce que
    - l'outil de poinçonnage/perforation (12) possède des poinçons/aiguilles de perforation (16) de différents diamètres.
  7. Machine de poinçonnage/perforation selon l'une des revendications précédentes,
    - caractérisée en ce que
    - un bloc de commande (14) est présent, lequel possède des unités piston/cylindre, dont les mouvements peuvent être commandés individuellement par le biais du dispositif de commande (30) lors d'une course de poinçonnage/perforation, et qui sont associées individuellement à chaque poinçon/aiguille de perforation (16),
    - un coulisseau d'arrêt (22), lequel est raccordé à une tige de piston (20) correspondante de l'unité piston/cylindre, le coulisseau d'arrêt (22) pouvant être déplacé dans une position d'activation ou de désactivation par le mouvement de la tige de piston (20),
    -- le coulisseau d'arrêt dans la position d'activation agit directement ou indirectement sur le poinçon/l'aiguille de perforation (16) lors de l'exécution de la course (H),
    -- le coulisseau d'arrêt dans la position de désactivation n'exerce aucun effet sur le poinçon/l'aiguille de perforation (16),
    -- de sorte que dans la position d'activation du coulisseau d'arrêt (22), celui-ci agit sur le poinçon/l'aiguille de perforation (16) lors du mouvement de course (H) et une perforation est effectuée, et dans la position de désactivation du coulisseau d'arrêt, aucun poinçonnage / aucune perforation de l'unité/bande de matériau (M) n'est effectué.
  8. Machine de poinçonnage/perforation selon la revendication 7,
    - caractérisée en ce que
    - l'unité piston/cylindre est réalisée sous la forme d'une unité piston/cylindre à double effet comprenant une première chambre de pression (28) et une deuxième chambre de pression (32), la première chambre de pression (28) étant soumise en permanence à une première pression (P1) par le biais du dispositif de commande (30), laquelle a pour effet que le coulisseau d'arrêt (22) se trouve ou est maintenu dans la position de désactivation et, lors de la réalisation d'un poinçonnage ou d'une perforation, le dispositif de commande (30) en cas d'activation soumet la deuxième chambre de pression (32) à une deuxième pression (P2), qui est supérieure à la première pression (P1), de sorte que le coulisseau d'arrêt (22) sort en position d'activation et ce mouvement est de ce fait transmis au(x) poinçon(s) / à (aux) aiguille(s) de perforation associé(s) lors du mouvement de course (H), de sorte qu'un poinçonnage ou une perforation de l'unité/bande de matériau (M) est effectué.
