Definitions

  • the invention relates to a reel winding device for winding a tapered Material web to a winding roll with a first support member having a circumferential Supporting surface, and a second support member by at least one Band is formed, which is guided over at least two pulleys whose axes of rotation are arranged parallel to the axis of the winding roll.
  • Such a reel winding device is known from DE 36 39 244 C2.
  • the first Support element is formed by a Tragwaize. Between the carrier roll and the Band is formed a winding bed in which the winding roll to a predetermined Diameter rests. As the diameter of the winding roll increases beyond that, The weight of the winding roll is increasingly on the upper run of the tape relocated. So you want to reduce the compressive stress, which is between the winding roll and the support elements results.
  • the band represents with its upper Trum an enlarged contact surface available, so that the compressive stresses accordingly lose weight.
  • the compressive stresses in the support chips are one of the criteria for the winding hardness of the winding roll. The winding hardness should be from the inside out decrease or at least remain constant.
  • the invention is based on the object, the printability of a in such Roll winding device wound paper web to Improve.
  • the printability problems include, among others Dust that results from winding.
  • Dust that results from winding.
  • causes of the dust development There may be microtractions between the reel and the belt. This dust not only settles uncontrollably on the reel winder, but he also gets between the individual layers of the winding roll. If now the tape makes it permeable to dust, then creates a path through which the Dust can be removed. The dust removal is by the dust removal device still encouraged.
  • the band can also have more than two pulleys be guided. Even in such cases but you will see the dust below the top Runs of the band can dissipate, i. the part of the tape on which the winding roll during winding rests.
  • the band has a flat perforation.
  • a flat perforation consists of a large number of holes or other openings, at least Almost uniform over the band are distributed. The dust can through this Holes and thus pass through the tape. The distance between the holes and the size of the holes are coordinated so that the tape the necessary Maintains strength and at the same time produces no markings on the web become.
  • At least the deflection roller which is the first support element adjacent to a gas impermeable surface. So long as the tape on this deflection roller rests, a dust passage is not possible. But at the same time Gas passage is not possible, so that, if necessary, between the first Support element and the pulley can produce a compressed air cushion, which also for weight relief of the winding roll is used
  • the dust removal device is designed as a suction device with Help a suction device can suck the dust through the tape and at the same time remove from the space below the upper run of the tape.
  • the required negative pressure must not be very large. He can even lower be as a negative pressure, which is used to suck the web on a roller or a another transport element needed to transport the web in its winding position.
  • the suction device has at least one suction box, which is arranged between the upper run and the lower run of the band is and the upper strand of the band facing top at least having a suction opening.
  • the suction box Through the suction box, the volume can be limited, in which the negative pressure must be generated. By the suction box so is the Air consumption while sucking the dust kept small.
  • the suction box the pulleys adjacent side walls has, which are adapted to the shape of the pulleys. In this case, you can maximize the size of the suction port or ports.
  • suction means comprises a lateral connecting piece for connection a suction line.
  • the dust is thus from the side of the reel winding device led out. This has the advantage that in the axial length of the reel winder no interruptions must be provided.
  • a plurality of bands are arranged at an axial distance from each other, and
  • the suction is also effective in the range of distances.
  • the second support element Thus, not only can a band have that over the entire axial extent passes through the reel winder, but it can from a variety of be formed narrower bands whose width is for example 200 mm. These Ribbons should not abut against each other during operation, in order to generate additional dust to avoid. Accordingly, smaller distances between the bands whose size ranges from 5 mm to about 20 mm. If you too through these distances between the bands can suck through, then will there dust removed. The dust is sucked out even without hindrance, so that the suction effect can be improved.
  • Fig. 1 shows a reel winding device 1 for winding a paper web 2 to a winding roll 3.
  • the winding roll is supported during winding on a roll 4, which forms a first support element 5, and on a belt 6, via two pulleys 7, 8 is guided, and a second support member 9 forms the band 6 can of course also be guided over more than the two pulleys 7, 8 shown, as is known for example from DE 36 39 244 C2.
  • the winding roll 3 is with increasing diameter on the upper run 10 of the belt 6 on. As the diameter of the winding roll 3 increases, its weight increases. This would lead without additional measures thatlielie compressive stresses in the bearing surfaces the winding roller 3 on the two support members 5, 9 increases. The compressive stresses but are decisive for the winding hardness. Accordingly, would the winding hardness of the winding roll 3 rise, which is not desirable. As a result of that you can support the winding roll 3 by means of the belt 6 on a larger area, an undesirable increase in compressive stresses is avoided.
  • the paper web 2 before the winding still be divided by longitudinal sections into several partial webs, which are then each wound to partial web roles. All bobbins have then essentially the same winding axes 11.
  • a suction box 12 which is open at its upper side 13, i. at least one ⁇ ffiung 14 (Fig. 2)
  • the suction box 12 has side walls 15,16 on which the pulleys 7, 8 are adjacent.
  • the side walls 15, 16 are so curved so that they follow the circumference of the pulleys 7, 8. This makes it possible make the top 13 and thus the opening 14 aslithzu.
  • the opening 14 can thereby cover almost the entire length of the upper run 10 in the circumferential direction.
  • the suction box 12 has on a front end on a connection piece 19 which with a suction line can be connected. Accordingly, air is continuously sucked through the opening 14
  • each Band 6, 6a-6e has an extension in the axial direction (relative to the deflection rollers 7, 8) of about 200 mm. Between adjacent bands 6, 6a-6e is a distance 17 present, which is about 5 to 20 mm.
  • the bands 6, 6a-6e are perforated flat, i. they have a multiplicity of passage openings 18 on, through the air and dust can occur.
  • This dust is created during winding. This may be due to microfriactions between the winding roll 3 and the bands 6, 6a-6e.
  • the dust is beating uncontrolled on the winding device 1 down, which is disadvantageous in itself.
  • you perforate the webs 6, 6a-6e, as shown, and at the same time sets the suction box 12 under negative pressure then you can see the dust through the bands 6, 6a-6e and by the distances 17 between aspirate the tape. It prevents not only that the dust in the Surrounding the reel winder 1 spreads. It also prevents the Dust is wrapped up with.
  • the paper web 2 remains "cleaner" and can later better be printed because the dust does not hinder printing.
  • the vacuum required to extract the dust is relatively small. He does not have to once as large as a pressure needed to hold on to a web start is, if you start the web with the help of a suction roller in the winding bed between wants to transport the two support elements 5, 9. Required is only one Underpressure capable of removing dust particles. Because these dust particles They are sucked off practically at the moment of their formation not fixed to other parts, so that basically no higher suction required is. This is especially true when the upper run 10 of the belt 6 moved away from the first support member 5 and the web 2 above the first support member 5 is supplied. In this case, the dust is mainly produced at the exit a Auflagenips 19 between the winding roll 3 and the upper run 10. There is the dust but immediately removed.
