Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the device can in one Longitudinal continuous sheets, individual sheet layers, Sheet ply stack or the like processed, e.g. precisely controlled be promoted. This allows successive sheet layers converted into a mutual relative movement, e.g. following sheets are quickly delayed and with slowly leading sheet layers are overlapped to then form flush stack from these sheet layers.
  • the sheet layers can be made of substrate material, e.g. Paper, exist or through sheet-like flat and flexible Layers.
  • fluid or pneumatic controls are used, which is a very gentle treatment, e.g. Fixing or mounting the Allow sheet layers by differential pressure. This can the respective sheet layer against a fluid-permeable system or contact surface sucked in and simultaneously by moving this facility will be promoted.
  • the fluid flow through the System or the like is due to narrowing or tight closing and expanding or opening a single or a plurality controllable by passages, which simultaneously on the respective Leaf position act.
  • the control takes place via a closing element, which compared to changing the passage cross sections the passage is movable, e.g. like a slide valve approximately parallel and / or across the sheet layer plane.
  • the closing element is suitably smaller than that for detecting the sheet position intended field of work, so that e.g. across and / or parallel for the control stroke, several locking members of the same size with one would fit next to each other, which is about half the distance Corresponds to the width of the individual closing member.
  • the individual Closing member controls a single passage.
  • GB-A-2 026 446 which corresponds to the preamble of claims 1, 5, 7, 10, 12 and 14, a device can be found at which each closing member has only a single control passage controls, in the closed position coaxial with this control passage lies, the cage can swing freely when unloaded, no protection is provided against dust pollution, each flow opening only communicating with a single additional port opening Cover is available and the locking elements are not available Lubricate the moving parts.
  • the invention has for its object a device to create the disadvantages of known training avoided or to achieve advantages of the type mentioned are and especially when there is little wear simple and compact training, high control accuracy or has a long service life.
  • the only one Passage gives way e.g. in axial view from a shape like it would be through a single circular opening. This means that this view is within a narrow range the perimeter of the perimeter circle at least one additional area, which at least partially slightly compared to that penetrated by the passage Control surface or the like. Transversely offset or in the plane this control surface can lie.
  • the additional area is partial or completely in one piece with the limitation of one or several passage openings and / or the control surface adjoining the boundary or envelope circle to the outside educated.
  • the passage can be through a single one, from the Circular deviating opening or through only two or more adjacent openings are formed, the clear distance is smaller than its width.
  • the closing member immediately after the passage opening limit and safely guided it prevents the unbroken sharp boundary edges this opening is the pressure-tight sliding on the control surface Wear the link surface too quickly.
  • the closing member can be proportionate be strongly pressed against the control surface and be Stroke can at most 0.9 or 0.8 times its width or its diameter.
  • the tax movement can be circular and / or back and forth, as a control stroke the path between two successive stoppages, e.g. one open position and one immediately following Closed position or vice versa can be seen.
  • the control stroke can be smaller than half the outer width of the Closing member or about the same size as the width of the above Envelope circle or at most by half or one One third larger than the width of the individual passage opening be. All mentioned widths can each have the minimum Maximum or medium width. Furthermore, the hub be at most half or a third larger than that Extension of the individual passage in the stroke direction. Appropriately this extension is smaller than the extension of the Passage perpendicular to the stroke direction. The greatest distance of the closing member or of its closing surface transversely or perpendicular to the stroke direction can be lower than the 1.8 or 1.5 times the corresponding extension of the culvert be.
  • the closing surface also needs the in the open position Passage not to release completely, but it can be in Axial view slightly into one or more passage openings protrude into it.
  • the additional area is advantageous one or both ends or over their entire length over the smaller extension of the passage continuously or in one piece up to the connection to the control surface in the area of Envelope circle and forms a section of the continuous one-piece control surface.
  • the effects described and other effects can also be achieved in that the closing member in the closed position relative to one or more associated Passage openings are eccentric.
  • the closing member in the closed position relative to one or more associated Passage openings are eccentric.
  • an axial plane parallel to the closing member in the stroke direction be offset.
