Definitions

  • the invention relates to a cutting and creasing device for paper or cardboard webs with at least two rotatably driven shafts, on which at least one tool carrier for a cutting or creasing tool is arranged, the tool carrier at least one radially movable, engageable with the shaft Has clamping jaw and an actuating device for the clamping jaw which can be controlled from outside the shaft.
  • Machines for longitudinal cutting and longitudinal creasing of paper or cardboard webs normally have at least one pair of rollers with an annular cutting or creasing mechanism testify to cut or creasing the continuous web in the longitudinal direction.
  • the position of the tools on the shafts must be readjusted.
  • the tools can be clamped on the shafts and can be removed again if necessary. So that the tools can be adjusted as quickly as possible, the aim is to automatically loosen and clamp the tools without manual intervention.
  • the shafts it is known to design the shafts as so-called expanding shafts, which can be expanded radially with the aid of a pressure medium in order to clamp the tools (DE-OS 2 250 508).
  • expandable hoses in the grooves of the tool shafts in order to clamp the tools.
  • the grooves are either ring-shaped or helical. Such a method has proven itself. However, wear is a disadvantage.
  • the invention has for its object to improve the cutting and creasing device mentioned above in such a way that the cutting and / or creasing tools can be clamped and released again in a particularly simple manner on a shaft.
  • the jaw is magnetically actuated via a power supply.
  • a plurality of magnetically actuated clamping jaws arranged radially and at the same circumferential distance are used.
  • the clamping jaw can itself be magnetic.
  • the clamping jaw can be actuated by an electromagnet. It is essential to the invention that the actuating force for clamping a tool on the shaft is applied electromagnetically. This requires a power supply to the individual jaws. However, this can easily be transferred to the movable shaft via slip rings.
  • One embodiment of the invention provides in this connection that two busbars rotate with a shaft and each tool holder is movable in the axial direction relative to the busbars and is insulated from the busbars and has two spring-loaded contact elements which are in contact with the busbars.
  • the busbars rotate with the shaft and extend through openings or recesses in the tool carrier. This means that the tool carriers can be moved freely on the shaft.
  • the Busbars can also be embedded in the shaft.
  • the contact elements for example carbon brushes, are in constant contact with the busbars in order to transmit the current from the busbars to the individual magnetic arrangements in the clamping jaws.
  • the busbars can be connected at one end to a slip ring arrangement.
  • the shaft itself can be used as a ground conductor, so that a busbar is in conductive contact with the shaft.
  • Another possibility is to assign a movable contact to each tool carrier instead of a busbar, which is constantly in engagement with the shaft and which is connected via a line to the individual magnetic arrangements in the jaws. In this case only one track is used.
  • the clamping jaws are assigned springs to the clamping jaws.
  • One possibility is to preload the clamping jaws radially away from the shaft with the aid of the springs, in order to achieve a quick release of the tool holder from the shaft when the magnetic excitation is switched off.
  • the clamping jaws are biased by a spring arrangement in the direction of the shaft. The springs ensure that the tools are clamped on the shaft, while the magnetic actuation is only used to temporarily release the tools.
  • pairs of shafts are used in such devices.
  • a counter tool for a cutting or creasing tool sits on the second shaft. Both shafts are rotated by a suitable drive device.
  • radial recesses 7 are formed in the tool carrier 1, in each of which a clamping jaw 2 is movably mounted.
  • the clamping jaws 2 are shaped to match the recesses, but can be adjusted to a limited extent in the radial direction without great effort.
  • the clamping jaws are adapted to the contour of the shaft 3.
  • Each jaw 2 is acted upon by springs 8 which press the jaws into engagement with the circumference of the shaft 3. As a result, the tool carrier 1 is clamped firmly on the shaft 3.
  • the clamping jaws can also be actuated by a magnetic actuation device, not shown, in such a way that when the magnetic arrangement is excited, the clamping jaws 2 are displaced radially away from the shaft 3 against the springs 8. As a result, the tool carrier 1 can be freely moved on the shaft 3.
  • the shaft 3 can be used as a ground conductor.
  • one of the two busbars 9, 10 can be electrically connected to the shaft 3.
  • a movable contact can be assigned to each tool holder 1, which is conductively engaged with the shaft 3. In all cases, it is ensured that the tool carrier 1 can be adjusted freely in the axial direction of the shaft 3. In the direction of rotation, however, the tool carrier 1 is fixed by the busbars 9, 10.
  • the system shown can also be used advantageously.
  • the springs serve to overcome any residual magnetism that may be present when the tool holder is released.
  • clamping jaws can be moved radially to a certain extent, as shown in the drawing. In this way it is possible to compensate for different transverse stresses on the tool.
  • two tool shafts 20, 2l are provided, on which a plurality of tool carriers with tools are arranged.
  • an upper tool carrier 22 and a lower tool carrier 23 are shown.
  • they contain an upper knife 24 or lower knife 25, which interact in a known manner.
  • Upper and lower tool carriers 22, 23 each contain four magnet arrangements 25 arranged at the same circumferential distance.
  • each magnet arrangement has a holding magnet 26, which is slidably mounted in a suitable housing of tool carrier 22 or 23 by means of a rubber sleeve 27 .
  • a flat rubber spring 28 is arranged on the side facing away from the tool shaft, which presses the holding magnet 26 against the shaft 2l with a certain pressure.
  • Busbars 29 and 30 are arranged insulated in a groove of the shafts 20, 2l.
  • a further busbar 3l, 32 is attached to the shaft 20 or 2l.
  • Each tool holder 22 or 23 has a brush arrangement 33 with brushes which are connected to the busbars 29 to 32 work together. As is not shown in FIGS. 2 and 3, the brush arrangement is connected to each magnet arrangement 25.
  • slip rings 35, 36 are fastened to the shaft 20 and 2l in an isolated manner.
  • the slip rings 35, 36 are connected to the busbars 29 to 32 via lines, not shown.
  • a brush arrangement 36 cooperates with the slip rings 34, 35, the brushes of which are connected to conductors which are connected to a voltage source of 24 volts.
