Definitions

  • the invention relates to a method for introducing a material web into a processing machine, in particular into a machine for winding paper or cardboard webs into winding rolls, according to the preamble of claim 1 and a device for carrying out the method. .
  • the invention has for its object to provide a generic method that enables safe introduction of a new material web with little design effort. Another object is to provide a device for carrying out a method according to the invention.
  • the first task is solved with the measures of claim 1. It has been shown that a belt can be transported by means of a laminar flow of compressed air along a guide element through a route provided with curves. Only a narrow web guiding element, preferably a channel, and flat jet nozzles arranged at regular intervals are required.
  • the guide element can have interruptions at the points crossing the web guide so that the path of the web is not impaired.
  • the elastic, tensile band is first introduced into the web guide section by means of compressed air, then it is pulled with the material web attached to it through the web guide section and thus removed again from the latter.
  • the feature of claim 3 ensures a safe transport of the tape through the web guide
  • the feature of claim 4 enables a reduction in the time required for the introduction, since the new supply roll can be prepared beforehand and only the tape to the during the downtime at the beginning of the material web attached connecting part must be coupled.
  • FIG. 1 shows a longitudinal section in the web running direction through a winding machine with a web insertion device according to the invention
  • Fig. 2 shows an enlarged section of the . Guide trough.
  • the winding machine shown schematically in FIG. 1 is a so-called back-up roll rolling machine, in which the material web 1, an up to 8 m wide paper or cardboard web, arriving from a roll 2 is divided lengthways into individual webs which are wound into winding rolls 3.
  • the winding rolls 3 are alternately arranged on both sides of the apex line on a driven support roller 4 during the winding.
  • the web 1 is brought up to the support roller 4 from below, so that it is partially wrapped around it.
  • a longitudinal cutting device 5 which divides the web 1 into individual webs.
  • a guide element preferably a guide channel 13 is arranged along the web guide path at a short distance from it.
  • the guide trough 13 has a U-shaped cross section and is open towards the web guide plane. Their width is between 50 mm and 100 mm, the height of the legs about 20 mm.
  • the trough 13 is located in the approximately horizontal part of the web guide section below it and extends to the last deflecting roller 11 in front of the longitudinal cutting device 5.
  • There is above the guide roller 8 a part 13.1 of the guide trough 13 which is curved in the shape of an arc of a circle and which is open at the bottom, wherein 1 spaces for the trough 13 have been left free for the crossing path.
  • the guide trough 13 is interrupted at regular intervals, approximately every 0.5-1 m.
  • flat jet nozzles 14 are arranged in each case, which blow compressed air flowing in the web running direction into the channel 13, the distance of the blow-out openings from the bottom of the channel 13 is less than 10 mm, preferably 0.5 mm - 1 mm.
  • the structure of such flat jet nozzles is described in DE-PS 24 13 614. In this way, the entire channel 13 is flooded by a laminar compressed air flow which is approximately parallel to its base.
  • a liftable and lowerable channel piece 13.2 is arranged, which can be raised between the extended knives of the slitter 5 to the upper guide roller 12 and lowered to below the lower guide roller 11.
  • a correspondingly curved guide trough part 13.3 In the area of the guide roller 12 there is a correspondingly curved guide trough part 13.3, at a distance from this - since at this point the web 1 again crosses the guide trough 13 - there follows a guide trough part 13.4 which reaches the support roller 4 approximately tangentially.
  • part 13.2 of the guide trough is first raised so that the vertical path between guide rollers 11 and 12 is bridged. Then the compressed air is switched on so that the entire guide channel 13 is flowed through by the unwind 2 to the support roller 4 of laminar flowing compressed air. Thereafter, a light, but tensile tape 15 made of paper, textile or plastic of a smaller width than the width of the guide trough 13 is introduced into the guide trough 13 during unwinding 2.
  • the belt 15 has a greater length than the belt guide section running under the floor and is transported by the compressed air through the channel 13 until its beginning emerges from the underfloor area on the support roller 4. At the end of the band 15 there is an attachment option for a connecting part to the material web.
  • kite is used as the connecting part, a trapezoidal connecting part which can be detachably fastened to the beginning of the new track 1, for example with an adhesive strip.
  • the kite is attached to the prepared web start of the new supply roll 2.1. After its end has been coupled to the kite, the band 15 in the region of the support roller 4 is pulled out of the guide trough 13 manually or mechanically and wound up in the process. In order to keep the tensile load as low as possible, the drive of the unwind 2 is switched on. The belt 15 thus pulls the new web start through the underfloor web guide section until the new web start emerges from the underfloor area on the support roller 4 and is taken over by the support roller 4 designed as a suction roller.
  • the end of the drag belt 15 is then released from the start of the web, the gutter part 13.2 is lowered, and the knives of the longitudinal cutting device 5 are moved to the web 1.
  • the transport of the new start of the web to the winding stations and the attachment of the individual webs to the respective winding cores is then carried out in a known manner with the support roller 4, on which the beginning of the web is sucked up.
  • the wound drag belt 15 is conveyed to the unwind 2 and is thus ready for the introduction of the next start of the web.
  • the belt 15 can already be guided through the guide trough 13 during the unloading of the full winding rolls 3.
  • the new supply roll is prepared outside the unwinding station by sharpening the beginning of the web and attaching a kite to it. After the new supply roll has been hooked into the unwind, only the end of the drag belt 15 needs to be attached to the kite.
  • the exemplary embodiment described above shows the introduction of a new web through the underfloor area of a winding machine which is difficult to access.
  • the method according to the invention is not restricted to these embodiments. It is beneficial on all processing machines - ⁇

Abstract

Pour l'introduction d'une bande de matière (1) dans une machine de traitement, en particulier dans une machine pour enrouler des bandes de papier ou de carton sous forme de rouleaux (3), un ruban (15) élastique et résistant à la traction est introduit dans le trajet de guidage de la bande par air comprimé soufflant essentiellement en écoulement laminaire et parallèlement à un élément de guidage (13) disposé le long du trajet de guidage. Ensuite, le début de la bande de matière (1) est fixé au ruban (15) et la bande (1) est entraînée avec le ruban (15) à travers le trajet de guidage de la bande. Un dispositif pour la réalisation du procédé présente un guide de trajet (13) s'étendant parallèlement et à faible distance le long du trajet de guidage de la bande (13), en particulier une goulotte en forme de U, sur lequel sont disposées à des intervalles réguliers des buses à jet laminaire (14).
