Definitions

  • the invention relates to a separating device for separating a material web, in particular a paper or board web, in the web running direction into a plurality of sub-webs, with a means for arc-shaped separation of the sub-webs.
  • a material web produced from a machine for producing a fibrous web from a pulp suspension is cut by cutting devices in the longitudinal direction into a plurality of side webs running in parallel.
  • a device for cutting elastic web-like material is known.
  • the knife can be fixed in various positions along the guide.
  • Each knife is mounted by means of a bearing block on a carriage which is displaceable along the guide.
  • a CCD camera such that it is capable of observing the cutting point created by the knife in the web.
  • the CCD camera is, for example, such a camera which scans its field of view line by line and is able to distribute each line into individual areas.
  • the camera is mounted on the carriage so as to be fixed so that the image taken by it can capture the cutting point and a small part of its surroundings; in the detection field, the cutting edges and parts of the knife should appear.
  • a position detection by the camera is achieved that the camera via a Control device may give a command to move the carriage serving to move the carriage a command for moving the carriage.
  • the part webs Before the partial webs can be wound up in a winding device comprising two winding rolls and lying flush in one of the roll beds formed by them, the part webs must be sufficiently separated in order to avoid mutual interference during the winding process. In addition, the individual coils must be separated from each other after completion of the winding process.
  • a means for arcuate separation of the partial webs serve, for example, rollers which are convexly bent over its entire width, so that the partial webs, which are guided over such a roller, are separated in the range of a few tenths of a millimeter from each other.
  • the same effect can also be achieved by a so-called Röllchenstreich instrumental.
  • many rolls are rotatably arranged on a transversely extending to the web running bar, which are movable by motor drives in the direction of the partial webs and can press against them so that the partial webs diverge slightly.
  • a further separating device for winding devices for longitudinally divided into several partial webs webs is known.
  • at least two rollers arranged substantially parallel to one another and bent in the same direction are provided with a stand for the pivotable mounting of the rollers about a common pivot axis.
  • the stand takes a support frame for rotatably supporting the two rollers about their respective axis of rotation and for pivoting the two rollers relative to the stator about the common pivot axis.
  • EP 0 829 438 B1 describes a back-up roll winding machine.
  • a material web is supported on a support roller, wound on a winding tube as it passes through a gap formed between the support roller and the winding roll to be produced, the winding roller being additionally supported by another device comprising two small rollers.
  • either only a single winding roll may be wound or a plurality of winding rolls each held in winding stations by individual tensioning devices, the tensioning devices alternating the winding rolls to both sides from a vertical axis passing through the center of the backing roll hold, wherein the connecting lines between the centers of the winding rollers and the support roller are inclined in each case to both sides of the vertical at an acute angle.
  • this object is achieved in a separating device of the type mentioned above in that at least one monitoring device is arranged in the region of the means, by which the distance of the partial webs can be monitored.
  • the invention can be used both in a double carrier roll winding machine and in a backup roll winding machine.
  • the invention enables automated operation of separating devices.
  • the separation of the sections of the material web, in particular the paper web, is now detected by the monitoring device.
  • the components required for the web separation can now be adjusted until the desired separation of the cuts is achieved. Even with fluctuating quality of the material of the fibrous web, the rejects are reduced by a fully automatic monitoring of the separating devices.
  • a plurality of monitoring devices are arranged side by side, each of which monitors two adjoining cut edges of partial webs.
  • the at least one monitoring device is preferably movable in the web running direction and / or transversely to the web running direction, in particular pivotable, so that all partial webs can be monitored with a single monitoring device and the monitoring device can be swiveled as required to critical points in the course of the part webs.
  • the at least one monitoring device is arranged to be movable in the web running direction or transversely to the web running direction on a carriage.
  • a single monitoring device can already be sufficient to determine different setting positions for the separating devices.
  • a separating device it is advantageous if signals generated and evaluated by the monitoring device, in particular those corresponding to the positions of the cut edges of the partial webs, are fed to a control or regulating device, so that a motorized adjustment of the separating device serving as the actuator, ie the rolls in the separating device, takes place automatically. In this way, the distances of the partial paths can be adjusted due to control or regulating signals.
  • a plurality of rolls may also be a spreader roll or a combination of several spreader rolls each having a convexly curved lateral surface, wherein the sheet height and / or the axial position of a spreader roll or the plurality of spreader rolls due to signals from a control or control device can be adjusted or leave.
  • the at least one monitoring device can thus be used in the region of a roller coating strip, a spreader roll or an arrangement comprising two spreader rolls arranged pivotably on a support frame.
  • both spreader rollers can be adjusted on the basis of optical signals obtained according to the invention.
  • the monitoring device is an optical device which can be embodied in various ways, for example as a camera, in particular as a CCD camera.
  • the monitoring device can also work with electromagnetic waves in the non-visible range or with ultrasound.
  • This shows a perspective view of a separating device with a roller coating.
  • a fibrous web 1 (FIG. 1) produced in a machine for producing a fibrous web from a pulp suspension is guided over a spreader roll 2.
  • the spreader roller 2 has a cambered shape, d. H. it has a convexly curved jacket 3, which serves to stretch the fibrous web 1 transversely to the web running direction.
  • the fibrous web 1 is cut by a respective lower blade and an upper blade comprehensive cutting devices 4, 5, 6 in mutually parallel partial webs 7, 8, 9, 10.
  • the partial webs 7 to 10 before being fed to a winding device, are fed to a single web separating device 11, by means of which they each receive a spacing of between 0 and 3 mm, preferably between 0.5 and 1 mm.
  • the separating device 11 either has a second spreader roll, which has the same shape as the spreader roll 2, or there is a roller coating strip 12, which comprises a multiplicity of rolls 13, which are juxtaposed over the entire web width of all sub-webs 7 to 10. These are individually adjustable by motor adjustment 14 to compensate for partially occurring web errors in the sub-webs 7 to 10, in particular at the edges, by readjustment of the sheet adjustment, which form the rolls 13 with each other.
  • cameras 15, 16, 17 are arranged as optical monitoring devices above or below the course of the partial webs 7 to 10 in the region of the separating device 11.
  • the cameras 15 to 17 are preferably arranged on a traverse (not shown).
  • the cameras 15 to 17 are additionally pivotable in the web running direction, so that they can observe the area of the cut edges between the part webs 7 to 10 over a large length. Additionally or alternatively, they are pivotable transversely to the web running direction.
  • the cameras 15 to 17 can be displaced on guide rails parallel to the cut edges of the partial webs 7 to 10.
  • the cameras 15 to 17 may additionally be pivotable in the transverse direction.
  • the cameras are arranged 15 to 17 on their own guides, for example, offset from one another, transversely to the web running direction.
  • the cameras 15 to 17 can each be moved individually and / or pivot.
  • the cameras 15 to 17 generate from the sub-webs 7 to 10, in particular from the areas of their cutting edges, recorded images of electronic signals which are supplied to a control or regulating device as a guide in which they are evaluated. By comparison with nominal values, control variables or control variables are obtained in the control or regulating device which are fed to the rollers 13 in order to adapt their position in accordance with the path of the partial webs 7 to 10. In this way, the invention ensures a continuous and uninterrupted monitoring of the separating device. It is understood that the cameras 15 to 17 can also be moved or pivoted in such a way that the cutting blades or the cutting devices 4 to 6 are additionally monitored in their function. According to the present invention, in addition to other optical devices, it is also possible to use the same optical devices as are already known from DE 295 04 644 U1.
