Definitions

  • the invention relates to a method for winding a goods tree in a transport device for a weaving mill.
  • the winding of a new goods tree is necessary when changing the goods tree on a weaving machine, since the fabric between the full goods tree and the weaving machine has to be severed if the goods tree is to be removed from the weaving machine by the transport device.
  • the goods tree and wrapping tree are pressed against one another with the interposition of the folding device and the fabric to be wound up. While the free end is folded in a V-shape, the V-shape being formed on the inside by the folding device and on the outside by the fabric tree and wrapping tree, the web of fabric to be wound up is tangentially transferred from the wrapping tree to the new fabric tree at the free end of the folding device.
  • the V-shaped free end of the fabric web between the surface of the new goods tree and the next fabric layer is pulled off the folding device and pressed firmly against the circumference of the goods tree. This ensures that the cut fabric is wound onto the new fabric tree without slipping.
  • the wrapping can also be carried out without a V-fold if the free end of the folding device lies practically congruent with the free end of the fabric web on the new fabric tree, so that no wrinkling occurs.
  • Fig. 1 the structure of the transport device 102 is partially shown schematically. It is divided into driving units 1a and 1b with wheels for carrying the entire device and a carrying unit 2 arranged between them.
  • the travel units each contain a travel drive, which Transport device leads through the weaving mill along a lane in the weaving room floor.
  • the carrying unit is drawn with a full goods tree 50, an empty goods tree 51, a winding tree 70 and with gripping arms 40a, 40b.
  • a cutting device 10 is indicated, which is movable in the longitudinal direction of the transport device 102.
  • a cross member 21 connects the right side part 20a to the left side part 20b, the cross member 21 being displaceable relative to the side part 20b.
  • telescopic rods 225 Between the side parts 20a and 20b there are several telescopic rods 225, with which the length of the transport device can be adapted for the type of weaving machine to be operated.
  • extendable supports 30a, 30b At the bottom of the side parts 20a and 20b are extendable supports 30a, 30b, by means of which the support unit 2 is supported on the weaving room floor while the goods tree is being changed.
  • the transport device 102 is located in a view in the longitudinal direction next to a weaving machine 500a.
  • warp threads 512 are fed to a sley 503, where the weft insertion takes place.
  • the fabric 510 is directed to a goods tree 50 via a goods take-off 504 and deflecting rods 505 and is wound up there.
  • the elements of the weaving machine mentioned are mounted between cheeks 506, which are held together by tubular cross members 507b and angular cross members 508b.
  • the cheeks 506 are supported on foot rails 509.
  • the fabric is wound onto the fabric tree 50 up to a maximum permissible diameter of the cloth roll.
  • a logistic control device of the weaving mill orders the transport device 102 to the relevant weaving machine 500a.
  • FIG. 2 shows the state in the transport device 102 after the full goods tree 50 has been removed from the weaving machine and shown before starting a new goods tree 51.
  • the gripping arms 40a, 40b with the legs 42 and 43 which are movable relative to one another have taken the full goods tree out of the weaving machine from the dashed position and inserted it into a carrying device 52a in the transport device 102.
  • the winding tree 70 has been raised from the lower position 70 'and is just released in the extended position by the gripping arms 40a and 40b.
  • the fabric 510 has formed a loop because it has been pulled up by the winding tree.
  • the winding tree is taken over by a manipulator 71 in the position shown.
  • a housing 710 of the manipulator is rotatably mounted about the axis of the new goods tree 51.
  • a lever 711 is rotatably mounted on the housing 710, the right end of which is pressed downwards or outwards by a compression spring 712.
  • the roller 713 at the right end of the lever 711 runs on the cam segment 714 when the housing 710 rotates clockwise, the lever 711 is pivoted about its axis relative to the housing 710 in a counterclockwise direction.
  • a trough 715 at the other end of the lever 711 comes into a position in which it can take over the winding tree 70.
  • the manipulator 71 is arranged on both sides 20a and 20b of the transport device.
  • the take-up tree After the take-up tree has been taken over by the manipulator 71, it rotates counterclockwise around the axis of the goods tree 51. As soon as the roller 713 is out of contact with the cam segment 714, the lever 711 is moved again clockwise by the spring 712. As a result, the surface of the winding tree 70 comes to the surface of the new goods tree 51. Now, the manipulation tree 70 is guided around the goods tree 51 counterclockwise by the manipulator 71.
  • the sequence of figures 3a - 3h shows the winding process.
  • the goods tree 51 is briefly driven clockwise, whereby the winding tree in contact with it forms a cloth reserve towards the weaving machine.
  • the tissue required for the formation of the cloth reserve is unwound from the full fabric tree 50 (FIG. 3b).
  • a cutting device 10 is brought up to the right from the tissue, which is then severed at this point. The cutting device 10 is then moved back to its original position while the winding tree 70 is moved further to the left.
  • the free end 510 'of the fabric then falls over the new fabric tree 51, whereupon it rotates clockwise until a certain free length of fabric 510' hangs from the fabric tree.
  • the winding tree 70 is still in contact with the fabric tree 51, which is why it makes a counter-rotation (FIG. 3d).
  • the winding tree 70 is pivoted back in a clockwise direction (FIG. 3e), whereby it rolls on the goods tree 51.
  • a cloth folding device 11 is moved downward until the free end 110 of a sword on the folding device touches the fabric tree 51 and the fabric presses against the fabric tree at this point.
  • the winding tree is now pivoted further clockwise with the aid of the manipulator 71 until it touches the free end 110 of the sword on the side opposite the fabric tree 51 (FIG. 3f).
  • the free end 510 'of the fabric and that above the winding tree 70 lying fabric is raised so that the free end 510 'of the fabric lies in a V-shape between the fabric tree 51, the sword 110 and the winding tree 70, and that the fabric 510 is tangential in the region of the free end of the sword 110
  • the winding tree 70 merges with the goods tree 51 (FIG. 3f '). Wrapping is also possible if the free end of the fabric web 510 ′′ protrudes only slightly over the free end of the folding device 11.
  • the wound goods tree 51 is then gripped by the gripper arms 40a, 40b and brought down into the storage location in the weaving machine.
  • the loosened part of the fabric section between the weaving machine and the new goods tree is tightened in an intermediate position of the goods tree, in which it is briefly driven counterclockwise.
  • the gripper arms 40a, 40b in the transport device move up again in order to grip the winding tree 70 and into the original position 70 'in the lower one Bring part of the transport device according to FIG. 2.
  • a manipulator to be described below is used for this.
  • FIG. 4 shows exemplary embodiments for the method of winding.
  • FIG. 4 is a partial perspective rear view of the side part 20b of the transport device shown in FIG. 1. 4 only individual elements of the side part 20b and the driving unit 1b are shown.
  • the driving unit 1b is supported on the weaving floor, among other things, by means of rollers 154. During the winding-up process, the otherwise rigid connection between the driving unit 1b and the side part 20b is released. The latter is supported in a lowered position on feet 23 on the weaving room floor, among other things.
