Definitions

  • the invention relates to a Tambourablagestation with a winding drum comprising a wound with a winding of a web winding core, and with a unilaterally fixed and fixed winding mandrel.
  • a material web in particular a paper, board, tissue or another fibrous web
  • an endless web is usually produced and rolled up on winding reels until a desired diameter is reached.
  • the wound-up material web is transported further for subsequent treatment in a processing machine, for example in a slitter-winder, a rerolling machine, a calender or a coater, and unwound again in a corresponding unwinding device. Both when winding and unwinding these winding tubes, certain amounts of reject material are produced. its treatment and return to the production process often leads to major obstacles to the production process.
  • Abrolling devices are known with a brake in which the Committee is passed web width in a resolver.
  • the unrolling of broke in a special unwinding device of the processing machine is also known.
  • the skinning of scrap layers or ply packages by hand in a roll-off device of a processing machine belongs to the state of the art. Also in Volltambourablagestationen is intervened manually to wait for layer packages.
  • the DE 41 41 242 A1 discloses a method and apparatus for preparing the start of a replacement roll for a flying reel change.
  • the web start is wound onto a wastepaper roll, brought by means of this in a processing position for the aforementioned steps, there applied the perforation in the web running direction another perforation transversely to the web direction, led the wastepaper to create the web start to the replacement winding roll and then by a Relative movement between the two separated the web at the latter perforation and finally removed after most each preparation cycle, the wound waste paper.
  • the DE 38 11 138 A1 discloses an apparatus and method for treating the end portion of a paper roll mounted on a paper feeder of a paper processing machine.
  • the device is moved towards the paper roll, until a pinch roller applies to the paper roll.
  • a cutter is applied against the peripheral surface of the paper roll and traversed transversely to sever a plurality of paper turns as a scrap.
  • the committee is picked up by a reception facility.
  • Another cutter is brought into contact with the central portion of the paper portion rolled up with the broke to form a center cut.
  • a cutout is formed. The upper part of a tab is pressed over the cutout to the paper end section.
  • Two knives seated on both sides of the paper end portion are moved transversely to the center while the paper is being rewound to form a V-cut leading to the cutout.
  • Adhesive is applied along the paper cutting edge.
  • the paper end is wound back onto the paper roll.
  • the tab is pressed against the paper roll.
  • the committee is issued.
  • the manual reject treatment is often associated with special risks for the personnel performing and makes, for example, the stay at the discharge chute required.
  • the staff can also be endangered by falling ropes. Likewise, only the train, which carries the web, a danger to the staff who must stay near the web.
  • this object is achieved in that the winding mandrel is drivable by a drive means that the winding mandrel is arranged in the rolling region of the winding drum at an angle to the longitudinal axis of the winding drum, wherein the angle has a value in the range of greater than 0 and less than 90 °, preferably in the Range of 5 and 45 °, that on the winding mandrel, the material web of the winding drum by means of a winding device is wound helically, and that the helically wound and sliding down from the winding mandrel web of a crushing unit, in particular two interacting knives or with teeth or spikes provided rolls, can be fed.
  • the material web is thus wound around the mandrel in the manner of a surrounding a cigar outer tobacco leaf.
  • Tambourablagestation comprises a rotating device for driving the winding drum, for example, a geared motor with an acting on the outer surface of the wound on the winding drum winding friction wheel.
  • the winding drum has a core drive, for example, with a slidable toothed coupling introduced in the drive shaft or the like.
  • the drum storage station is either fed by a spool transport system or by a tambour crane.
  • the wound on the reel spool web is disposed of by a preferably provided with a low-friction surface mandrel, a drive means for helically wrapping the winding mandrel with the material web and an asymmetrically slotted guide channel or a guide trough are used, which surrounds the helically wound material web from the outside and conduct.
  • the web start is preferably detected by a drive belt, which wraps around the winding dome at the largest possible angle, with the aid of an insertion aid, for example a vacuum belt.
  • the insertion aid consists for example of a drive roller with a drive device and a deflection roller with a corresponding storage.
  • the drive device may be, for example, an electric motor or a fluid-operated motor.
  • an air-permeable and circulating endless belt made of a flexible material, for example a perforated plastic web, a mesh or the like, out.
  • a loading device for example, a fluiddruckbeetzyerter actuator, for producing the contact between the endless belt and the material web on the winding core.
  • a vacuum channel which is the belt strand on the side of the expiring Material web is open.
  • This vacuum channel is provided with a device for generating a negative pressure, which acts on the open side of the vacuum channel through the circulating endless belt and for the detachment of the web start from the winding core and its reliable transport to an inlet point of a waste treatment device.
  • the belt guide is arranged opposite to the material web and / or the mandrel entangled.
  • a web of material to the winding mandrel pressing drive roller is provided. The web tension is kept approximately constant by a brake acting on the winding drum.
  • the material web is wound on the winding mandrel by a pneumatic drive, in particular by a cyclone.
  • the winding axes of the winding cylinder and the winding mandrel are arranged at an acute or obtuse angle and also by the entanglement of the belt guide a feed of the material web is generated, the resulting helical material web sleeve along the axis of the winding mandrel continuously in the direction of an ever greater center distance between the winding drum and the winding mandrel moves.
  • the winding mandrel is surrounded by a, in particular asymmetrically equipped with slots, guide channel for guiding the helically wound material web or that, in particular asymmetrically equipped with slots, guide trough is arranged on the underside of the winding mandrel.
  • the guide channel is arranged either on the inside of the sleeve formed by the material web or on the outside of the material web sleeve.
  • the guide channel or the guide trough has a circular or helical cross-section.
  • the lateral surface of the winding core is characterized by a low coefficient of friction in order to promote the sliding of the inside of the material web sleeve surrounding it.
  • the length of the winding mandrel extends substantially from its one-sided attachment region outside the winding device, that is outside of the range in which the material web is received helically, at least over the wrap around by the drive or drive belt or the attack region of the drive roller. Another measure to reduce the friction is that the winding mandrel has an inner channel, from the shell-side holes compressed air against the winding mandrel-side inner surface of the material web is pressed.
  • the material web slides on a conveyor belt, in a leading to a dissolver shaft or is fed to a suction device.
  • the drum storage station is either arranged separately or it is integrated in a magazine for full, reject or residual reboots; However, it can also be integrated into an overall transport system for wound or empty reels. Due to the compact design and the lateral material web discharge also the installation in a spool magazine can be realized on a machine scooter.
  • the advantages of the solution is that a relatively small installation space is required, that there is little need for manual intervention and that the site of the Abschwart raised is not directly tied to the installation of the resolver.
  • the web run speed can be controlled according to demand. Due to the continuous processing of the existing waste quantity, there is only a small requirement for the maximum dissolving capacity.
  • the invention is applicable regardless of the respective winding diameter and can be easily combined with Tambourtransportsystemen.
  • a reel storage station 1 comprises a winding drum 3, which is rotatably mounted on a storage rack 2 and is driven by a drive (not shown here), for example a core drive.
