Definitions

  • material webs are often processed.
  • paper webs are fed to a further processing, individual pieces of material being cut, folded, printed or otherwise processed from the paper webs.
  • a pulp fiber web is subjected to further processing steps, from the pulp fiber web handkerchiefs or other hygiene articles cut to the desired size and the resulting pieces of material then suitably folded and packaged, for example.
  • the material is usually guided in the plant provided for processing via a multiplicity of transport or processing devices.
  • functional rollers are used, over which the material webs or pieces of material guided and thereby deflected or possibly only supported. If required, such functional rollers can be provided with cutting devices, embossing devices or the like, in order to be able to process them as required during the course of the respective material via the roller to make the material.
  • Such a functional roll or functional roll can be embodied as a so-called suction roll system, with which the material draining off the roll is sucked as needed onto the functional roll or functional roll, so that a good adhesion of the material guided over the roll or roll can be ensured.
  • Saugwalzensystem as for example from the DE 10 2009 033 575 A1 is known, usually comprises a rotatably mounted cylindrical suction roll whose cylinder jacket is provided with a number of forming a perforation suction holes or suction slots, which are individually or groupwise selectively connected to a vacuum system via a control system.
  • a control system By means of a suitable control, individual suction holes or selected groups of suction holes are purposefully connected to the vacuum system, so that in the region of the respectively controlled suction hole, the material piece is sucked onto the suction roll and held thereon.
  • suction holes are usually via a system of suction channels, which are guided within the roller body in the longitudinal direction and branch off at the location of the respective suction hole radially outward and open into the respective suction hole, connected to the end face of the roller body.
  • a so-called control head is arranged in the holding frame of the suction roll, which has a number of control openings, which in turn are connected to a vacuum system.
  • an overlap of the frontal outlet of the respective suction channel with a control opening in the control head may then occur, so that in this case the corresponding suction hole is connected to the vacuum system.
  • the negative pressure at the respective suction hole can be switched on and off again as required, so that it is possible to act on the respective suction hole under vacuum with exact timing.
  • the suction passages connecting the suction holes to the control head on the vacuum side usually have a comparatively unfavorable length-cross-section ratio, so that the gas exchange in the respective suction channel is subject to a comparatively high flow resistance when switching between negative pressure mode and normal pressure mode.
  • the switching times achievable with such a system are therefore only limited, as are the degrees of freedom in the group-wise common or simultaneous activation of a plurality of suction holes.
  • a suction roll system in which within a rotatably mounted suction roll a provided with a number of control slots vacuum cylinder is arranged.
  • this system also has no flexibility in the group-wise control of suction holes.
  • the invention is therefore based on the object of specifying a Saugwalzensystem of the above type, with the reliable way particularly short switching times and also a high degree of flexibility in the group-wise control of a plurality of suction holes can be achieved.
  • the invention is based on the consideration that the switching times achievable in the control of the suction holes or suction slots and thus the possible process speeds in the overall system depend to a considerable extent on the channel geometry in the connection of the suction holes with the vacuum system.
  • the aim should be to keep the connection channels as short as possible and the channel cross sections as far as possible.
  • it is provided to consistently position the space area (in the case of previous systems the control head in the support frame of the suction roll) as close as possible to the area of the suction holes so that the connection channels between the suction hole and the permanent negative pressure can be kept particularly short.
  • a projecting into the suction roll hollow cylinder is provided, the interior of which should be permanently exposed to negative pressure during operation of the system.

  • the hollow cylinder has in its cylinder jacket on a number of control slots. A control, so a vacuum-side connection of the respective suction hole with the vacuum chamber, is given when the respective suction hole sweeps over one of the control slots in consequence of the rotation of the suction roller.

Due to the position of the respective control slot, ie in particular its start and end point and its length in the circumferential direction, Thus, the desired timing for the respective suction hole can be preset properly. In particular, it is thus possible by the appropriate positioning of a plurality of such control slots, which may differ from each other in relation to their starting and / or end points, the specification of a control pattern for the totality of the suction holes, so that a particularly suitable for the respective plant process control pattern the suction holes is made possible via the appropriate attachment of suitable control slots in the cylinder wall of the hollow cylinder.

  • an additional storage on a at the end of the Hohlzylin ders arranged storage system may be provided.
  • the suction holes to attach in a particularly simple manner possible by the suction roll and, if appropriate, the distributor casing arranged therein are drawn off from the free end of the hollow cylinder and optionally replaced by replacement parts.
