Definitions

  • the invention relates to a support roller winding machine for winding material webs, in particular paper or cardboard webs, onto cores according to the preamble of patent claim 1.
  • roll ejection and sleeve insertion devices which eject the full rolls from the roll bed when a roll is changed and insert new sleeves into the roll bed.
  • DE-OS 40 03 504 describes a support roller winding machine which contains an ejection roller as ejection device, which is on the side, around the axis the swivel arms on the inlet side, which pivot the web from below into the roller bed and are freely rotatable.
  • a device for applying an adhesive and a perforating device with which the web can be weakened are arranged in front of the feed roller on the inlet side.
  • the web is first weakened and the weakened point is moved into the roller bed.
  • the web is then severed by increasing the tension by rotating the winding roller with the outlet-side support roller, while the ejection roller raises the winding roller somewhat from the inlet-side support roller.
  • the full winding rolls are then ejected from the discharge roller via the discharge roller on the outlet side.
  • the ejection roller can eject full winding rollers with a larger diameter (e.g. 1000 mm) via the outlet-side support roller, it is necessary to arrange them at a certain radial distance from the inlet-side support roller. However, then it will not be able to lift winding rolls with a smaller diameter (e.g. 200 mm) from the infeed roller to cut the web.
  • a larger diameter e.g. 1000 mm
  • it will not be able to lift winding rolls with a smaller diameter (e.g. 200 mm) from the infeed roller to cut the web.
  • a carrier roller winding machine for winding material webs with two driven carrier rollers is known, in which the material web is deflected from the inlet-side carrier roller and guided from below into the roller bed.
  • a pushing device is arranged so that it can pivot about the inlet-side support roller.
  • the pressing device consists of a box-shaped part which is pivotally attached to swivel arms and to which two pressure rollers are fastened at the front, one of which is mounted so as to protrude somewhat from the box-shaped part.
  • the pressure rollers which are guided in a side link guide, lift the winding roll from the inlet-side support roller and press it over the outlet-side support roller. Winding rolls with very little diameter are lifted by a web holding device that can be raised between the support rollers so that they can be pushed by the front pressure roller over the outlet-side support roller.
  • the invention has for its object to improve the winding reel ejecting device in a generic carrier roller winding machine so that it is able to lift winding rollers with widely different diameters both from the inlet-side carrier roller for severing and to eject from the roller bed via the outlet-side carrier roller.
  • an ejection device with an ejection surface is used for ejecting a full winding reel from the roller bed, which is arranged for ejecting winding reels with a large diameter at a sufficient distance from the inlet-side support roller.
  • a lifting roll is arranged in the free space between the ejection surface and the supporting roller, which is as close as possible to the supporting roller and is thus able to lift small-diameter winding rolls.
  • the freewheel lock which only acts in one direction of rotation, enables winding rollers to be removed from the roller bed, the diameter of which is too small for ejection. These winding rollers can be clamped between the support roller on the outlet side and the lifting roller and can be lifted by rotating this support roller until they are clamped between the ejection surface and the support roller and are raised further.
  • the new sleeves can be inserted simultaneously with the ejection of the full winding rolls.
  • a separate sleeve insertion device according to claim 3 enables the use of sleeves with a very large diameter.
  • the carrier roller winding machine has two driven carrier rollers 1, 2, between which a roller bed 3 is formed, in which the winding rollers 4 rest on the carrier rollers 1, 2 during winding.
  • Such double carrier roll winding machines are widely known and z. B. described in DE-OS 32 07 461, so that individual parts, insofar as they do not relate to the invention, are not dealt with.
  • a downwardly angled pivot lever 8 is pivotally mounted in the machine frame by means of a piston-cylinder unit about an axis coaxial with the axis of rotation of the support roller 1.
  • the levers 8 carry on their upper side a roller lifting and ejecting device with an integrated sleeve insertion device, which is described in more detail below.
  • each swivel lever 8 On the upper side of the radially extending part of each swivel lever 8 there is an extension of the working width outside the cross-sectional area of the support roller 1 extending ejector 9 attached.
  • the ejection device 9 consists of a bearing part 10 which is approximately fork-shaped in cross section and which is open in the direction of the pivoting-in movement to the roller bed 3.
  • a lifting roller 11 At the free end of the arm of the bearing part 10 adjacent to the supporting roller 1, a lifting roller 11 extending over the working width of the machine, that is to say over the axial length of the supporting rollers 1, 2, is mounted with the smallest possible distance from the supporting roller 1.
  • the lifting roller 11 is freely rotatable in the same direction as the direction of rotation of the supporting roller 1 - in the exemplary embodiment counterclockwise - rotation in the opposite direction - ie clockwise - prevents a freewheel lock, not shown.
  • a lever 12 is articulated to which the ejection surface 13 is attached.
  • the ejection surface 13 can be folded about an axis parallel to the support roller axis 1 by means of a piston-cylinder unit 14 attached to the angled part of the swivel arm 8 and is supported in the folded-down position on the arm of the bearing part 10 adjacent to the support roller 1.
  • the piston-cylinder unit 14 is only indicated in FIGS. 1 to 6 and is shown in more detail in FIGS. 7 to 9.
  • the ejection surface 13 extends in the radial direction to the support roller 1 from the area of the lifting roller 11 to the extent that heavy winding rollers 4 can be easily ejected via the support roller 2 from the support roller bed onto a pivotable lowering platform 15 arranged next to the support roller 2.
  • the bearing part 10 carries between its arms a sleeve groove 16 which extends over the working width, wherein the outlet opening of the sleeve groove 16 between the lifting roller 11 and the lever 12 can be opened and closed by pivoting the ejection surface 13. So that the lifting roller 11 can lift a winding roller 4 slightly from the support roller 1 without the winding roller 4 immediately contacting the ejection surface 13, it protrudes somewhat from the ejection surface 13 when it is folded down in the ejection position with the outlet opening of the sleeve channel 16 closed . In the folded-down position, the ejection surface 13 thus extends at an acute angle to the tangent to the outer side of the lifting roller 11 which runs through the axis of the support roller 1.
  • the web 6 On the inlet side, just before the web 6 touches the support roller 1, there are a perforating device 17 and subsequently in the area wrapped by the web 6 Carrier roller 1 arranged a number of tape dispensers 18 across the working width. With the perforating device 17, the web 6 can be weakened along a transverse line.
  • the adhesive web dispensers 18 apply a series of double-sided adhesive tapes to the web 6, with which the newly created beginning of the web after the web 6 has been cut through is glued to the new sleeves 7 and the web ends to the finished winding rolls 4.
  • a machine-wide support 19 is arranged, to which a number of free-running belts 20 are fastened over the working width, which are moved by moving the support 19 up to the inlet-side support roller 1 to hold the newly created web start after cutting put on.
  • FIGS. 2 to 6 In the carrier roll winding machine shown in FIG. 1 during winding, a winding roll change is carried out as shown in FIGS. 2 to 6.
  • a set of new winding tubes 7 is inserted into the tube channel 16 and this is closed by folding down the ejection surface 13.
  • the machine is then stopped and the web 6 with the perforating device 17 is weakened along a weakening line 21.
  • tape strips 22 are applied by the tape dispensers 18 on both sides of the weakening line 21, and the support 19 is raised with its tip through the support roller nip, so that the strips 20 hold the web 6 on the support roller 1.
  • the lowering platform 15 is pivoted upward to accommodate the full winding rolls 4 on the support roller 2 (FIG. 2).
  • the swivel arms 8 are then swiveled further upward, so that the ejection surface 13 presses the winding rollers 4 away over the support roller 2 onto the lowering platform 15.
  • the sleeve channel 16 moves with the set of new sleeves 7 into the roller bed 3 (Fig. 4). In this position, the ejection surface 13 is opened up so that the sleeves 7 roll into the roller bed 3 from the inside of the ejection surface 13 (FIG. 5).
  • the sleeves 7 roll into their winding position in the roller bed 3.
  • the winding machine is started.
  • the beginning of the web provided with an adhesive strip 22 adheres to the sleeves 7 (FIG. 6).
  • the support 19 is lowered with the belts 20 and the winding machine can be accelerated to full winding speed.
  • the swivel arms 8 With a new set of sleeves 7 resting in the sleeve groove 16, the swivel arms 8 are swung over the supporting roller 1 until the lifting roller 11 bears against the winding rollers 4 to be ejected and presses them against the supporting roller 2 with a defined force (FIG. 7).
  • the support roller 2 is then driven clockwise.
  • the rollers 4 are raised by the rotational movement of the support roller 2, since the free-wheel lock of the lifting roller 11 does not permit a clockwise rotational movement.
  • the piston-cylinder unit permanently presses the swivel arms 8 in the direction of the support roller 2, so that the ejection surface 13 rests on the rollers 4 as soon as these have lifted so far that they are no longer held by the lifting roller 11.
  • the winding rollers 4 between the support roller 2 and the ejection surface 13 are conveyed up into the region of the apex line of the support rollers 2 (FIG. 8), where they are opened by opening the ejection surface 13 over the apex of the support roller 2 Lowering platform 15 can be pushed.
  • the ejection surface 13 is opened, the new winding tubes 7 are simultaneously placed in the roller bed (FIG. 9). The track starts will be then attached to the new sleeves 7 in the manner explained under the description of FIG. 6.
  • FIGS. 1 to 9 show a carrier roller winding machine with a separate sleeve insert device 24 which can be pivoted about the outlet-side carrier roller 2.
  • the components which correspond to the exemplary embodiment according to FIGS. 1 to 9 are identified by the corresponding reference numbers.
  • a separate sleeve insertion device 24 may be required if sleeves 7 with such a large diameter (z. B. greater than 230 mm) are used that there is not enough space available for installing the insert device in the ejection device 9.
  • the sleeve trough 16 is attached to the end of two swivel arms 25 which can be swiveled counterclockwise around the axis of the outlet-side support roller 2 from a lowered sleeve receiving position to an approximately vertical position, in which the sleeves 7 from the sleeve trough 16 into the roller bed 3 roll.
  • the ejection device 9 carries the lifting roller 11 in the extension of the ejection surface 13. In this embodiment, too, the lifting roller 11 protrudes somewhat against the ejection surface 13, and thus the ejection surface 13 extends at an acute angle to the tangent extending through the axis of the support roller 1 to the outer side of the lifting roller 11.
  • the upper limit of the ejection surface 13 extends in the forward pivoted position into the region of the apex line of the outlet-side support roller 2, so that winding rollers 4 with very little diameter are clamped between the ejection surface 13 and the support roller 2 and removed from the roller bed 3 by a rotary movement of the support roller 2 can be.
  • a winding roll change is carried out analogously to the process according to FIGS. 2 to 6, with the difference that after the winding rolls 4 have been ejected and lowered with the lowering platform 15, the ejection device 9 with the lifting roll 11 is pivoted back into the waiting position and then the new ones Sleeves 7 are inserted into the roller bed 3 by pivoting the swivel arms 25. Already during the pivoting back of the sleeve channel 16 the new web beginnings can be glued to the new sleeves 7. In the embodiment according to FIG. 10, a roll change takes a little more time, since the new sleeves 7 are not inserted into the roll bed 3 at the same time as the full winding rolls 4 are ejected, but in a separate step.
