Definitions

  • the present invention concerns a method according to the preamble of claim 1.
  • Fig. 1 shows four views of cores during different stages whil carrying out an embodiment of the method according to the present invention.
  • Fig. 2 shows three views of cores during different stages while carrying out an embodiment of the method according to the present invention.
  • Fig. 3 shows three views of cores during different stages while carrying out another embodiment of the method according to the present invention.
  • Fig. 4 shows three views of cores during different stages while carrying out yet an embodiment of the method according to the present invention.
  • Fig. 5 shows a layout of a device for carrying out the method according to the present invention .
  • the method according to the present invention will now be described in connection with the preparation or gluing of large cores, e.g. 2540 mm long and having a diameter of 305 mm, onto which non-self-supporting material is wound, e.g.
  • a used core is cleaned of residual material and glue residues.
  • Such an initial core 1 is shown in Fig. 1, and at both ends of the initial core 1, a core piece 2 and 3 is cut off.
  • the length of the core pieces 2,3 may be 50-100 mm.
  • a lengthening core 4 is machined in one of the ends for forming a joint surface 5, which is internal and conical.
  • One of the ends of the cut off initial core 1 is machined for forming a joint surface 6, which is external and conical.
  • the conicity of the joint surfaces 5 and 6 fits to each other.
  • a suitable glue is put on one of or both joint surfaces 5 and 6.
  • the glue may be a cold-water glue or a combination of a cold- water glue and a hot-melt glue.
  • the initial core 1 is assembled with the lengthening core 4 for compression of the joint surfaces 5 and 6 with each other. Compression is effected for a predetermined period of time, e.g. from a number of seconds (e.g. 30 s) to a number of minutes (20 min) depending on the type of glue.
  • the length of the initial core 1 provided with the lengthening core 4 is adjusted to the correct and desired length. If the lengthening core 4 has a length of the total length of the core pieces 2 and 3 plus the horizontal joint surface length, it may be possible to avoid the adjusting cutting of the new reusable core 1 with the glued-on
  • a combination 7 of an initial core with a glued-on lengthening core is shown. From the combination 7, a core piece 8 and a core piece 9 are cut off. The end of the
  • combination 7 which lacks a lengthening core piece, is machined for forming a joint surface 6, which, as in the preceding embodiment, is external and conical for co-operation with a lengthening core 4 having a corresponding joint surface 5.
  • the combination 7 is assembled with the lengthening core 4 for compression of the joint surfaces 5 and 6 with each other for a predetermined period of time. After confirmation of whether the combination 7 with a new lengthening core 4 has the correct length, it can be reinstalled into the reeling machine.
  • the embodiment shown in Fig. 3 is in principle the same as the embodiment disclosed in connection with Fig. 2 except that the combination 7 is turned or rotated half a turn so that the end, which is provided with the lengthening core 4, points in the opposite direction.
  • FIG. 4 there is shown an embodiment, according to which core pieces 8 and 9 are cut off from a combination 7, and the lengthening core end of the combination 7 is machined for forming a joint surface 6 for assembling with a joint surface surfaces 5 and 6, the parts are pressed together for a
  • FIG. 5 there is shown a layout of a machine for carrying out the method according to the present invention.
  • the lengthening cores are moved by means of the discharger 4 and are placed on a conveyor 6 for lengthening cores by means of a transfer robot 5.
  • This robot 5 also transfers cut off core pieces
  • a transfer robot 7 moves lengthening cores from the conveyor 6 to a processing and gluing unit 11 for forming a joint surface.
  • An end-cut core is moved by the discharger 4 to a table 9 having means for zero line adjustment and further to a feed unit 10, by which the core is fed into the processing and gluing unit 11 for forming a joint surface.
  • glue application the joint surfaces are being pressed together and held pressed together for a predetermined period of time.
  • the core provided with lengthening core is placed on the table 12 for further transfer to the grinding unit 13 and a core cutter 14 for removal of surplus glue and length correction.
  • the machine is controlled from an operator console 15.
  • a suction unit 17 is arranged for dust extraction. Furthermore, the machine is surrounded by a protection fence 18, and in the machine, a number of electric cabinets 16 are also included.
