Definitions

  • the invention relates to a method for winding webs of material, in particular paper or cardboard webs, onto cores according to the preamble of patent claim 1 and a carrier roller winding machine according to the preamble of patent claim 2.
  • 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.
  • a generic method and a support roller winding machine with the features of the preamble of claim 2 is described in DE-PS 31 51 256. There, the roller ejection and the sleeve insertion device are structurally separate and each can be pivoted separately in the direction of the support roller bed.
  • a carrier roller winding machine with a combined ejection and insertion device according to the preamble of claim 5 is described, which consists of an ejection bar and a collet, which are attached to a common lever and so together from the outside a support roller can be pivoted to the roller bed.
  • the ejection surface of the ejection bar extends approximately radially to the pivoted support roller. It ends at a distance from the support roller that is larger than the sleeve diameter so that the collet integrated in the ejection bar can take up the sleeves through the space and insert them into the support roller bed.
  • the ejection and insertion device of this winding machine additionally has a holding device between the clamping jaws of the collet, with which the winding sleeves can be lowered onto the support rollers without twisting after swiveling over the roller bed.
  • a disadvantage of all these known carrier roller winding machines is that the winding rollers must have a minimum diameter so that they can be ejected from the ejection bar, since the winding rollers must be pushed up to the apex line of the second carrier roller during ejection.
  • the minimum diameter is more than twice as large as the distance between the lower end of the ejecting surface of the ejecting bar and the supporting roller, which is pivoted, for the function of the inserting device.
  • rollers In practice, it can happen for various reasons that a complete set of rollers must be declared as a scrap and removed from the roller bed shortly after the winding. For rolls that have not yet reached the minimum diameter, they must then be lifted out of the roller bed manually. Since the rollers already have a considerable weight, this places a considerable burden on the operating personnel.
  • the invention has for its object to provide a generic method with which wound rolls with a small diameter can be removed from the roll bed.
  • Another object is to provide a generic support roller winding machine which is capable of removing coiled rolls with a small diameter from the roll bed.
  • the first object is achieved with the measures of claim 1.
  • the second object is achieved both with the features of claim 2 and with the features of claim 5.
  • the ejecting and inserting device according to claim 5 can be converted to eject rolls with a small diameter, at the same time protecting the sleeve inserting elements against damage.
  • the elastically attachable ejection surface according to claims 3, 4 and 10 ensures constant contact at approximately the same pressure between the ejection surface, the pinched roller and the support roller.
  • the carrier roller winding machine has two 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.
  • the material web which is divided lengthways into individual webs, preferably a paper or cardboard web, is guided from below - deflected by the support roller 1 - between the support rollers 1, 2 into the support roller bed 3 and wound onto sleeves 5 aligned.
  • Such double carrier roller winding machines are known, so design details are not discussed.
  • a lever 6 is pivotally articulated coaxially to the axis of rotation of the support roller 1.
  • the pivoting movement is carried out by means of an adjusting unit - in the present example a hinged piston-cylinder unit 7.
  • the piston-cylinder unit 7 is designed to be somewhat flexible in both pivoting directions, so that the levers 6 are elastically coupled within limits.
  • the free ends of the levers 6 are angled in the direction of the roller bed 3 and carry a roller ejection and sleeve insertion device 8, which is described in more detail below.
  • an ejection bar 9 extending across the working width is attached.
  • the ejection bar 9 is fastened to additional swivel arms 10 which are articulated on the levers 6 and which can be swiveled relative to the levers 6 in the direction of the supporting roller 1 by means of a piston-cylinder unit 11.
  • the ejection bar 9 is firmly connected to the levers 6.
  • the ejection bar 9 is used to eject a finished winding roller 4 via the support roller 2 onto a lowering platform 12. Its ejection surface 13 facing the support roller 2 is shaped approximately to match the circumference of a winding roller 4 and extends approximately radially to the support roller 1. 1-3, dash-dotted lines), the ejection surface 13 extends to the vicinity of the apex line of the support roller 2.
  • the roller ejection and sleeve insertion device 8 contains a collet 14 for inserting new sleeves 5 into the roller bed 3, the clamping jaws of which are located in the area between the ejection bar 9 and the supporting roller 1.
  • the collet 14 is attached to the angled part of the lever 6.
  • the construction of such collets is known and e.g. described in DE-OS 35 27 377 or in DE-PS 29 48 877.
  • the ejection surface 13 is extended to the area of the collet 14 to such an extent that when the swivel arm 10 (FIG. 2) is swiveled forward, it extends to just before the support roller 1.
  • the swivel arm 10 (FIG. 2) is swiveled forward, it extends to just before the support roller 1.
  • a machine-wide extension plate 15 is articulated on the end of the ejection surface 13 facing the support roller 1 about a pivot axis 16 parallel to the support roller axes.
  • the sheet 15 can be pivoted back so far that it bears against the ejection surface 13 and thus releases the required space for the supporting roller 1 for inserting sleeves 5.
  • the sheet 15 can be folded down to just before the support roller 1 in order to extend the ejection surface 13 to the support roller 1.
  • the double carrier roll winding machine described above works as follows:
  • empty sleeves 5 are placed in the chuck 14 in the waiting position and held by the latter.
  • the ejection bar 9 is pivoted in the direction of the roll bed 3 and thereby pushes the full roll 4 from the roll bed 3 onto the lowering platform 12.
  • the collet 14 with the empty sleeves 5 is simultaneously moved in the direction of the roll bed 3, where the tongs 14 opens and the sleeves 5 are placed on the support rollers 1, 2.
  • the support rollers 1, 2 are set into a rotational movement for winding up.
  • rollers 17 with such a small diameter have to be removed from the roller bed 3, in which the ejection and insertion device 8 is no longer functional in the manner described above, the swivel arms (10) are in the waiting position relative to the levers 6 in the direction of the roller bed 3 pivoted ( Figure 2) or the extension plate 15 is folded down towards the support roller 1. In this way, a surface extending to the support roller 1 is created in each case.
  • the levers 6 with the piston-cylinder unit 7 are then pivoted in the direction of the roller bed 3 until the ejection surface 13 (FIG. 2) or the extension plate 15 (FIG. 3) on the Rollers 17 abuts and presses them against the support roller 2.
  • the support roller 2 is now driven clockwise (arrow 18).
  • the rollers 17 are conveyed up between the support roller 2 and the ejection surface 13 or the extension plate 15 up to the apex line of the support roller 2, from where they roll automatically onto the lowering platform 12.
  • the roller ejection device 8 and thus the ejection surface 13 is designed to be flexible in both pivoting directions, so that the contact between the support roller 2, the rollers 17 and the ejection surface 13 is constantly maintained with approximately the same pressure.
