Definitions

  • the invention relates to a support roller winding machine for winding a material web, in particular a paper or cardboard web, on winding cores, with a device for inserting a new winding core into the carrier roller bed and for separating the material web, in which a receiving element for the sleeve and a web separating element on a double articulated lever are attached, which is pivotable about an axis parallel to a support roller axis.
  • Carrier roll winding machines are used, in particular, for winding paper or cardboard webs from a supply roll onto individual smaller rolls, at the same time the web drawn off from the supply roll being cut into individual webs in the longitudinal direction. They have two or more support rollers, the winding rollers being wound up in the axial direction next to one another in the support roller bed between two support rollers on sleeves. After the winding rolls have reached the desired diameter, the ones coming from the supply roll are cut lengthways Separate individual webs, unload the full winding rolls and insert new winding tubes in the carrier roller bed, to which the newly formed start of the individual webs are wound.
  • a carrier roller winding machine in which a perforating strip is fastened to a shell segment held between two shields, which can be pivoted about an axis which is parallel to the carrier roller axis but is arranged eccentrically.
  • Levers are pivotally mounted on the shields and carry a trough-shaped receptacle for a new winding core between them.
  • the lever and thus the receiving trough with the new winding core can be pivoted relative to the shields until the receiving trough is located above the gap between the two support rollers.
  • the web is severed by ejecting a full winding roll from the carrier roller bed, the web tearing at the perforated point. While the newly formed start of the web is clamped onto the support roller, a new winding tube is inserted into the support roller bed.
  • a disadvantage of this device is that the point at which the web is severed cannot be varied. It has been shown that when using sleeves with different diameters problems arise when attaching the new web start to the new winding tube if the length of the web start up to the line of contact of the winding tube with the support roller is not adapted to the respective tube diameter. In the case of cores with a larger diameter, the length of the beginning of the web between the severing line and the line of contact of the winding core with the support roller must be greater than in the case of winding cores with a smaller diameter.
  • DE-A 36 40 724 shows a generic carrier roller winding machine in which a receiving element for the new sleeve and a separating element are pivoted about the wrapped carrier roller. Since the sleeve crosses the path of the web on its way to the end position in the carrier roller bed, it must be severed before the sleeve is inserted. An additional holding device is required to hold the web when it is cut. There are no means of adapting the dividing line of the web depending on different sleeve diameters.
  • the invention has for its object to provide a generic carrier roll winding machine with a sleeve arming element and web separation element fastened to a common swivel arm, in which the position of the dividing line of the web can be changed in a structurally simple manner depending on the tube diameter.
  • the support roller winding machine has two support rollers 1, 2, between which a roller bed 3 is formed, in which the winding rollers rest on the support rollers 1, 2 during winding.
  • the material web 4 - preferably one Paper or cardboard web - is guided from below, deflected by the support roller 1 through the gap between the support rollers 1, 2 into the winding bed 3.
  • Such double carrier roller winding machines are known, so design details are not discussed in detail.
  • a pivoting lever 5 is articulated in the frame of the winding machine about an axis parallel to the support roller axis; In the present example, the pivot axis runs coaxially to the axis of rotation of the support roller 2.
  • a further pivot lever 6 is articulated, which can be pivoted relative to the pivoting lever 5 by means of a piston-cylinder unit 7 fastened between it and the pivoting arm 5, the pivoting movement in the direction of the pivoting lever 5 being limited by adjustable stops 8.
  • a sleeve groove 9 extending across the working width is fastened in an adapted recess.
  • the side of the free end of the pivoting lever 6 facing away from the support roller 2 has an extension 10, at the end of which a guide tube extending transversely across the working width is attached for a separating knife 11 movable parallel to the support roller axis.
  • the extensions 10 extend approximately to the area of the apex line of a winding tube of maximum diameter inserted into the tube groove 9.
  • the pivoting movement of the pivoting-in levers 5 is carried out by means of chain wheels 12 which are fastened coaxially to their pivot axis and which are driven by chains 13 by a driven pivot shaft 14 with chain wheels 15 at both ends which extends across the working width.
  • the shaft 14 also ensures a synchronous pivoting-in movement on both end faces of the support roller 2.
  • a swiveling inspection platform 18 is arranged next to the winding machine for manual fastening of the newly formed path start to the new winding tubes 16, 17.
  • 1 shows the loading position in which sleeves 16 with a small diameter or sleeves 17 with a large diameter are inserted manually or automatically into the sleeve groove 9.
  • the pivoting arms 5 are inclined downward by approximately 45 degrees and the pivoting arms 6 are approximately vertical, which was brought about by completely extending the cylinders of the piston-cylinder unit 7.
  • the completely wound rolls are ejected from the winding bed 3. They are on a half-lowered lowering platform, not shown.
  • the material web 4 is not yet severed. It therefore connects the finished rolls to the supply roll, the web 4 being under tension.
  • the cutting edge of the axially movable cutting knife 11 is in the rest position outside the area of the material web 4, and the inspection platform 18 is placed vertically.
  • the swivel arms 6 are first swiveled in the direction of the swivel arms 5 by means of the piston-cylinder unit 7. This pivoting movement is limited by the stops 8. With sleeves 17 with a large diameter, this swiveling movement is minimal, with sleeves 16 with a small diameter, the swivel path is longer (FIG. 3).
  • the pivoting arms 5 are then pivoted counterclockwise about the axis of the support roller 2 by means of the drive device 12-15, that is to say in the direction of the roller bed 3.
  • the rollers 16 and 17 roll over the inclination of the sleeve trough 9 against the support roller 2, whereby they are carried along by the part of the sleeve trough 9 adjacent to the support roller 2.
  • the guide tube After the guide tube has reached the material web 4, it begins to press it with increasing pivoting movement in the direction of the support roller 1 and thus creates space between the material web 4 and the support roller 2, so that the sleeves 16 and 17 respectively can roll further and further in the direction of the roller bed 3 until they have reached the roller bed 3, that is to say they rest on both support rollers 1, 2.
  • the pivoting movement is stopped in this position (FIGS. 2, 4).
  • the cutting knife 11 is then moved across the entire width across the material web 4, the tensioned web 4 being severed.
  • the length of the newly created free path start a or b is determined by the previously set angle between the swivel arms 5 and the swivel arms 6.
  • the distance a between the cutting position of the cutting knife 11 and the line of contact of the winding sleeve 17 in the roller bed 13 is greater than the corresponding length b for sleeves 16 with a small diameter (FIG. 4).
  • the complete device - as shown in FIG. 5 - is pivoted back into a lower parking position.
  • the swiveling inspection platform 18 is then folded into a horizontal position so that the operating personnel can enter it in order to fasten the newly created start of the material web 4 to the sleeve set.
  • This attachment is problem-free since a free path start adapted to the respective sleeve diameter has been created.
  • the inspection platform 18 is again folded vertically and then the tube insertion device is pivoted back into the starting position according to FIG. 1 for receiving a new tube set.
