Definitions

  • the invention relates to a device for guiding a web from a first position to a second position, in particular from an unwinding station to a winding section of a reel winder, with an auxiliary device which engages the web at the first full-width position.
  • a web in particular a paper web, withdrawn from a supply roll, passed through a longitudinal cutting device and then fed to a winding section, where the then present in partial webs web is wound on partial web rolls.
  • These partial web rolls can be wound, for example, in a double take-up roll winder or in a support or contact roll winder.
  • the web must be guided from the unwinding station to the winding section.
  • German patent application 10 2004 049 720 proposed to detect the web with an auxiliary device and then to guide the auxiliary device along the predetermined path. For this purpose, it is necessary that the auxiliary device can detect the web over its full width.
  • the invention has for its object to easily detect a web in the region of its beginning in full width.
  • the auxiliary device comprises a tube which encloses an interior, which is acted upon by negative pressure, wherein the tube has on a part of its circumference a flat outer surface through which a Saugö Stammsan extract with at least a suction opening is led to the interior.
  • the auxiliary device is inexpensive to manufacture as a pipe.
  • the tube In the tube is the interior, in which the negative pressure can spread evenly across the width of the web available.
  • This Flat surface can be accommodated accordingly relatively large suction openings, so that the web can be applied over a correspondingly large area with negative pressure.
  • the web does not have to deform in the system at the auxiliary device. This keeps the risk of damage small.
  • the suction forces applied to the web via the suction opening assembly can be fully utilized to hold the web. If the flat outer surface is parallel to the web, then gaps between the web and the outer surface can be avoided. Compared with a tube having a cylindrical cross-section, significantly improved holding forces result.
  • the tube is held at both ends in each case a carrier. So you can decouple the function of the tube to hold the track, and decouple the transport properties.
  • the tube is used exclusively for the temporary attachment of the track.
  • the guidance of the tube along the path of movement is then taken over by the carriers. Accordingly, it is sufficient to use the tube in the carrier. Further processing of the pipe is not required.
  • at least one carrier has a rotary drive acting on the tube. This makes it possible to put the tube with sucked web start in rotation, so that the web start is wound one or more times around the pipe.
  • the forces required to move the web along the trajectory between the first position and the second position then no longer have to be applied exclusively via the negative pressure become.
  • the vacuum rather serves to hold the beginning of the web during winding on the pipe. By winding forces then arise in the manner of a rope friction, which in any case sufficient to pull the web along the trajectory.
  • the tube has a curved shell with an opening into which an insert with a flat contact surface is inserted.
  • This facilitates the production on the one hand.
  • shell a half-shell or a shell which extends over a correspondingly larger or smaller circumferential angle.
  • Such a shell can be easily bent from a sheet or cut from a tube semi-finished.
  • the insert can be used. It is then possible to design the insert exclusively for cooperation with the web, in particular in view of the fact that the web should not be damaged when sucked to the auxiliary device.
  • the insert projects beyond the edge of the opening.
  • the insert thus covers the rest of the tube so far that the web comes into contact with the tube only insofar as it is wound around the circumference of the tube.
  • the insert is formed of a plastic.
  • a plastic is arbitrarily malleable in many areas. So you can easily adapt it to the required requirements. In particular, in a plastic, which is usually softer than a metal, there is less risk of damage to the web when pulling.
  • a sealing arrangement is arranged in the region of the suction opening.
  • a sealing arrangement may be formed of an elastic material, which is formed for example moss rubber-like. If a seal arrangement is present, then the web can better conform to the auxiliary device. The air loss during suction is lower.
  • the flat outer surface has a lower roughness than the curved portion of the outer surface.
  • the contact surface, which is formed by the flat outer surface may be ground, for example. This also reduces the loss of air when the web is sucked once.
  • the auxiliary device cooperates with a pressure device.
  • a pressure device presses the web against the flat contact surface. Thereafter, the negative pressure can be generated.
  • webs with a larger basis weight, such as cardboard sheets it is achieved so that the negative pressure holds the web securely to the auxiliary device.
  • Fig. 1 shows a schematic representation of a roll winding device 1 with an unwinding station 2 and a winding station 3. Between the unwinding station 2 and the winding station 3, a longitudinal cutting device 4 is arranged.
  • an unwinding position 5 is provided in the unwinding station 2 in the unwinding position 5 .
  • a master roll 8 To the spool 7, a master roll 8 Towikkelt, of which a remainder is still visible in Fig. 1.
  • a web 9 is withdrawn.
  • This web 9 is cut in the slitter 4 in several sub-webs and wound in the winding station 3 to several bobbins 10, of which in Fig. 1, only one can be seen because these bobbins 10 are in a direction perpendicular to the plane behind the other.
  • the unwinding 6 is suitable for higher speeds.
  • the web 9 can be withdrawn at a speed of 2000 to 3000 m / min.
  • the winding rollers 10 rest on two support rollers 11, 12, of which at least one is driven.
  • a loading roller 13 may be provided to control the winding process.
  • a back-up roll winder in which the winding rollers 10 are held centrally and bear against a support or contact roller.
  • the unwinding station 2 also has a preparation position 14, in which a further reel 15 with a new master reel 16 is kept ready.
  • the preparation position has a preparation bearing 17, which also allows a rotation of the main cylinder 15, but is less expensive, because the necessary rotation speeds are much lower.
  • the preparation bearing 17 and the unwinding bearing 6 are interconnected by a track 18 on which the spool 15 in the preparation position 14 to the unwinding position 5 can roll when a reel change is required.
  • the mother roll 16 is prepared. As a rule, some layers of the web are handled and disposed of in preparation. This process is also referred to as "stalling".
  • a pulper opening 19 is provided, which is arranged below the preparation position 14 in such a way that under the action of gravity hanging down web 9 hits the pulper opening 19. Because the mother role 16 does not always have the same radius, the position of the drooping web 9 will move slightly. However, the pulper opening 19 is so large that it can catch the falling web.
  • a hopper 20 may be additionally provided.
  • the roll winding device 1 For insertion, the roll winding device 1 an auxiliary device 21, which is shown in Fig. 1 at different positions. In different positions, the auxiliary device 21 is provided with small letters (a, b, c) for distinction.
  • the auxiliary device 21 is guided on a movement path 22, which is shown as a dashed line.
  • the trajectory is realized by rails or guides, which are arranged on both sides of the web 9 outside its width.
  • a chain, a belt or a rope can be performed, these devices are driven in a manner not shown by a common drive, so that the auxiliary device 21 in an orientation perpendicular to the direction of movement of the web 9 of the unwinding station. 2 can be performed to Aufwickelstation 3.
  • the auxiliary device 21 is now moved from the left (relative to the illustration of Fig. 1) to the under the action of gravity vertically hanging down web 9 and attached to the web.
  • auxiliary device 21 in an embodiment which differs slightly from the illustration of FIG. 1.
  • the auxiliary device 21 is namely driven from the other side against the web 9.
  • the auxiliary device 21 detects the web 9 in the area of the jumbo roll 16. Otherwise, however, the auxiliary device 21 is in principle just as usable as in the embodiment according to FIG. 1.
  • Fig. 3 shows the auxiliary device 21 in cross section.
  • the auxiliary device 21 has a tube 30 which surrounds an inner space 31.
  • the tube 30 is formed from a half-shell 32 into which an insert 33 is inserted.
  • the half-shell 32 engages in grooves 34 which are formed on the two longitudinal sides of the insert 33.
  • the insert 33 is slightly up and down on the half-shell 32, so that it covers the end face of the half-shell 32, so to speak, completely.
  • the insert 33 has a height which corresponds approximately to the diameter of the tube 30, if this had a completely circular cross-section.
  • a plurality of suction openings 35 are formed. If now the interior 31 with a negative pressure is acted upon, then this negative pressure acts on the suction ports 35 to the outside. Now, if the web 9 rests against the outside of the insert 33, then it is sucked through the suction openings 35 on the insert 33 and thus on the tube 30. As can be seen from the right half of FIG. 5, one can surround the suction openings 35, each with a seal 36.
  • This seal 36 is formed of an elastomeric material. It can for example be formed mousse-like.
  • the suction openings 35 are not surrounded by a seal. It is also possible to provide the surface of the insert 33 with increased smoothness, for example by grinding, so that the web 9 rests smoothly and no gaps are created through which air could penetrate into the interior 31.
  • the auxiliary device 21 is to be arranged approximately at the height of the axis of the jumbo roll 16.
  • auxiliary device 21 with a Allow pressure device 37 to interact.
  • the pressure device 37 has a punch 38, which can be displaced under the action of a drive 39 in the direction of a double arrow 40, ie in the direction of the auxiliary device 21 to or away from it. You can then use the punch 38 to press the web 9 against the insert 33.
  • the tube 30 is mounted at its two ends in carriers 41, 42. The one carrier 42 is shown in dashed lines, so as not to obscure the view of other elements of FIG.
  • the carriers 41, 42 are then movable along the movement path 22.
  • the tube 30 is rotatably mounted in the carriers 41, 42.
  • the carrier 41 has a rotational drive 43 shown only schematically, with which the tube 30 can be rotated to wind the web 9.
  • the suction force is sufficient to hold the web 9 during the winding on the tube 30 on the pipe 30.
  • a cross-cutting device 23 can still be provided which separates a section 24 of the web 9, which then falls into the pulper opening 19. If only a short piece of the web 9 projects down over the auxiliary device 21, then it is easier to wind the web 9 on the auxiliary device 21.
  • the auxiliary device 21 has a width which is greater than the width of the web 9.
  • the tube 30 is thus at the two longitudinal edges of the web 9 slightly over the web 9 on. The supernatant does not have to be large. But it should be sufficient to prevent a conflict between the web 9 and the two carriers 41, 42. This also applies if the carriers 41, 42, which are shown only schematically in FIG. 2, are made smaller.
