Definitions

  • the invention relates to a cutting and transport roller according to the preamble of claim 1 and a method for influencing the support behavior of a material web on the peripheral surface of the roller.
  • Such a cutting and transport roller is from the US-A-5109741 known.
  • a cutting and transport roller is out of the EP 0 698 671 A1 known.
  • the roller described there has an inner cavity into which a separating body is inserted.
  • This separator and the outer shell of the roller limit pressure chambers.
  • the pressure chambers are in contact with the environment via passage holes in the circumferential surface of the roller.
  • the pressure chambers are connected via pressure medium lines arranged outside the roller overpressure or vacuum sources, so that if necessary in the pressure chambers, a negative pressure or an overpressure is generated, which acts on the running on the peripheral surface of the roller material web. As a result, the material web is held on the roller (negative pressure) or repelled by it (overpressure).
  • the described roller is usually used in winding devices for winding the material webs.
  • the web must be severed after the formation of a complete roll and the new web start to be applied to a new winding tube.
  • For cutting the web serve separation devices, which are also integrated in newer winding devices in the roll.
  • Such a separation device is for example in the DE 100 47 545 A1 described.
  • the Separating elements of these separators occur briefly through the peripheral surface of the roller and thus cut through the material web.
  • the pressure chambers are subjected to a negative pressure, so that the material web is held on the roller. If the web start now reaches the new winding tube, the pressure chambers are subjected to overpressure. The material web is now pushed away from the roller and onto the winding tube. This process is referred to as Anwickelvorgang.
  • the DE 4000078 A1 shows a knife roller for the production of window letter envelopes.
  • the knife roller On a squeegee with suction ports, wherein the squeegee is angularly fixed in its phase relation to the incoming and outgoing roller.
  • the WO 00/71332 A2 shows a device for processing web material.
  • the apparatus comprises a cutting roll which includes vacuum-charged holes to hold the material on the surface.
  • the US 5,918,518 discloses a device for cutting sheet material.
  • the device comprises two winding and cutting rollers, which are each mounted opposite to the device.
  • the cutting rollers comprise holes that can be acted upon by means of a pressure chamber with positive or negative pressure.
  • the DE 43 08 710 A1 and WO 02/070213 A1 describe a method for removing blank debris from a punching knife on a rotating punching drum.
  • the waste pieces are removed from the punching knife of the drum by means of a blast of compressed air.
  • the punching drum is hollow. Their interior is pressure tight and is connected via a compressed air line with a compressed air compressor - which is located outside the drum - in conjunction. The compressor ensures a constant pressure of 6 bar in the drum.
  • the WO 02/070213 A1 shows a punching drum for punching paper from paper webs.
  • a suction hood is provided, which sucks the knife outside the drum.
  • the suction hood is pressurized by a compressor with negative pressure.
  • the in the EP 0698 671 A1 described cutting and transport roller has voluminous cavities in its interior, through which the pressure mediating media - of course usually air - are supplied to the media outlet openings.
  • these media of so-called “pressure sources”, ie any pumps, which are located outside the roller, the roller supplied.
  • the object of the present invention is to propose a cutting and transporting roller with which the setting and / or repelling of the material web, even at high peripheral speeds, can be accomplished more reliably.
  • the media outlet openings can be subjected to the desired pressure virtually instantaneously.
  • pumps require a lead time.
  • the valve which delimits the pressure reservoir is mounted as close as possible to the media outlet openings. This is particularly the case when voluminous chambers are provided as pressure supply lines as in the EP 0698 671 A1 ,
  • Such a valve can be designed as a changeover switch, with which you can switch between the different pressures back and forth. However, it can also be provided several valves, which operates as a circuit breaker can be. It is advantageous in both embodiments, that already on one side an excess or negative pressure applied to the valves and upon actuation of the valve in a very short time a pressure change occurs at the media outlet openings. In this way, the support behavior of the material web on the peripheral surface of the roller can be influenced much more precisely in terms of time than in the described prior art.
  • air is used as the media.
  • the cutting and transport roller comprises a pressure reservoir, which is arranged in the roller and whose connection with the media outlet openings with the at least one valve is interruptible.
  • a pressure reservoir which is arranged in the roller and whose connection with the media outlet openings with the at least one valve is interruptible.
  • two pressure reservoirs are used, each for overpressure and underpressure.
  • both the positive or negative pressure is available immediately when needed.
  • An arrangement within the roller also offers the advantage that the media supply system does not include rotary unions, which can lead to media loss. As a result, higher pressures can be provided.
  • the at least one pressure reservoir is designed as a media tank, which is introduced as a separate component in the roller. Such a roll construction minimizes the production costs considerably.
  • the media tanks can be designed, for example, as a cylinder.
  • the roller and the pressure reservoirs have independent walls.
  • the media tanks can be arranged so that their main axes of inertia coincide with the axis of rotation of the roller.
  • the pressure medium tanks can then be pressurized via pipes from the outside with the pressure media of different pressures. This process can also be done at a time where the media is not retrieved from the media reservoirs. It then also plays essentially no role when media are lost through the necessary rotary joints.
  • the invention further comprises a method according to claim 3 for influencing the support behavior of a material web on the peripheral surface of a cutting and transporting roller.
  • This method is generally used to carry out the Anwickelvorgangs already described in the introduction to this time more precise and thus more reliable especially at high speeds than with the above-discussed known method according to EP 0698 571 A1 to design.
  • a static pressure is initially built up in components of the pressure supply system by the means for providing media of different pressure, and the media outlet openings are acted upon by the opening of valves with this pressure.
  • FIG. 1 shows a cutting and transport roller 1, whose ends have journals 2. Between the two bearing journals 2 there are two fluid tanks 3, 4 which together with the bearing journals 2 represent components of the axis of the cutting and transporting roller 1. The journals 2 are traversed in the axial direction with pipe penetrations 5, via which the media tanks 3, 4 can be acted upon with media. On the media tanks 3, 4 circular disk-shaped web plates 6 are pushed, which carry the outer shell 7 of the roller. The web plates 6 have flats 8, on which a maintenance flap, not shown, can be attached. The web plates 6 continue to carry the cutting device 9, of the example, some cutting blades 10 are shown. For a more detailed description of the cutting device is on the DE 100 47 545 A1 directed.
  • valves 11 are arranged on both sides, which are each connected to two fluid tanks 3, 4 via lines 12. About these valves 11 so the media from both media tanks 3, 4 have been forwarded to the media outlet openings 14.
  • An arrangement of valves 11 on both sides of the cutting device 11 allows the operation of the cutting and transport roller in both directions of rotation.
  • the valves 11 direct the media, as already mentioned, to the media outlet openings 14, which are introduced as radial bores in the media strips 13, which may be formed as a hollow body.
