Definitions

  • the invention relates to a device for optionally cutting, cutting or perforating paper, cardboard or similar, preferably film or tape-like wound materials, consisting of a cutting tool guided in a frame and possibly a paper guide or support for the substantially perpendicular to the direction of movement materials fed to the cutting tool.
  • Cutters are known for paper strips that are supplied as roll-shaped material and separated into cards, stamps or similar paper sections. For example, tickets, stamps or tickets of different sizes and with different cuts are separated in automatic cutters.
  • the feed of the paper material is interrupted during the cutting process, so that a straight separating cut can be carried out. This prevents the material from running quickly and the cutter's mechanics are subject to heavy wear due to high acceleration and deceleration forces.
  • the object of the present invention is to develop an automatically operating cutter or a device for selective cutting, cutting or perforating of the type mentioned in such a way that different cutting positions can be achieved without retrofitting the machine and a fast passage of the materials with an angle of rotation of 360 ° without stopping / starting in the cutting position.
  • the cutting tool 10 is movably arranged in lateral guides 12, 13 of the housing 1.
  • the housing 1 can be designed as an almost closed housing.
  • paper guides (not shown in FIG. 1) and slots 17 or 26 (FIG. 4-6) or guide rollers formed correspondingly perpendicular to the image plane are provided.
  • the housing 1 there is also an eccentric axis 9 on which an eccentric wheel 4 is rotatably mounted.
  • the eccentric axis 9 runs parallel to the material web, so that the eccentric wheel 4 rotates parallel to the direction of movement of the cutting tool 10.
  • rocker 3 On an extension 15 of the movable cutting tool 10 there is a rocker 3 attached via an axis of rotation 2.
  • the rocker 3 extends from the lower part of the extension 15 of the cutting tool 10 to the area of the eccentric axis 9.
  • a link in the rocker 3 6 molded in, which receives the eccentric pin 5 and guides almost without play.
  • the rocker 3 is raised or lowered over the link 6.
  • the extent of the lifting movement depends on the direction of rotation of the eccentric bolt 5, since the link 6 is designed asymmetrically in its upper end regions 6.1, 6.2 with respect to the central axis M.
  • Figure 2 shows the conditions on the rocker in a cross-section according to Figure 1.
  • the rocker 3 and the eccentric pin 5 are in the central position M.
  • the eccentric wheel 4 is turned clockwise, the eccentric pin 5 is in the upper position 6.1 Backstage 6 brought.
  • the eccentric bolt 5 moves counterclockwise, it is brought into the position 6.2 of the link 6. It can be seen that the stroke difference between the positions 6.1 and 6.2 results from the change in the direction of rotation of the eccentric pin 5.
  • the cutting tool 10 is taken along via the axis of rotation 2, so that the change in the direction of rotation and thus the stroke difference also affects the movement of the cutting tool 10.
  • FIG. 3 shows the cutting tool 10 with lateral guide sections 10.1, 10.2 and the lower extension 15 as a section from FIG. 1.
  • the movement of the rocker 3 about the axis of rotation 2 can also be seen, the movement of the rocker 3 being stabilized by an additional spring 16 in the central axis M.
  • the spring pressure also achieves a play-free, form-fitting contact between the eccentric pin 5 and the link 6.
  • the eccentric wheel 4 can be driven by a motor 7 and a worm 8.
  • the motor can be set up for clockwise or counter-clockwise rotation or for both directions of rotation, or it can be connected to the worm or the eccentric wheel via a clutch and possibly via a gear.
  • FIG. 4 A variant of the device according to the invention according to FIGS. 1 to 3 is shown in FIG. 4, an additional straight guide in the housing 34 being used for the power transmission from the worm wheel or link wheel 22 to a rocker 36. If necessary, the use of a straight guide allows the use of low-friction sliding films between the moving parts.
  • the material to be cut e.g. Roll paper or plastic films is moved through a slot 26 in the housing 34, the paper or film guide being carried out perpendicular to the plane of the illustration.
  • the positions of the cutting tool 27 which can be seen from FIGS. 4 and 5 represent the maximum depth of cut with the largest stroke.
  • FIG. 5 shows the maximum depth of cut of the alternative cutting device with a small stroke in the counterclockwise direction.
  • the different stroke movement is brought about by the formation of the semicircular groove 28 in the link wheel 22.
  • the semicircular groove 28 has a left and right end point 28a, 28b, so that, depending on the direction of rotation, the pin 29 strikes either one or the other end point. This results in the different stroke movements.
  • FIG. 6 shows the position of the cutting tool 27 in the lower position, in which the paper slot 26 is completely released is.
  • the pin 29 has now reached its lower position, so that it bears in a form-fitting manner against the groove boundary 28b. Further details, in particular the position of the attachment point 30 in the cutting tool 27, the spacer 30 and the counterpart 33 can be seen in FIG.
  • the power transmission from the worm wheel or link wheel 22 to the rocker 36 takes place via a pin 29 which is firmly connected to the rocker.
  • the rocker 36 is rotatably connected to the cutting tool 27 via the rocker bearing 38.
  • the rocker bearing 38 also serves in connection with the shoulder screw 30 as a fastening point of the cutting tool 27 with a straight guide, consisting of a spacer 39 and a counterpart 33.
  • the spacer 39 slides in a recess 31 of the housing 34.
