Definitions

  • the invention relates to a transport device for a weaving mill according to the preamble of claim 1.
  • the warp threads are wound onto so-called warp beams for weaving on a weaving machine, whereby the warp beams can have considerable dimensions and a large mass.
  • the woven cloth is wound onto a fabric tree, which is removed from the weaving machine from time to time when the wound fabric has reached its maximum permissible diameter.
  • the fabric beam usually has to be changed several times, whereby the weaving machine should preferably not be taken out of operation.
  • a transport device which is intended for two-man operation and which is divided into two driving units and a carrying unit.
  • the carrying unit can on the one hand be arranged displaceably relative to the driving units and on the other hand can be rigidly coupled.
  • the driving units can be arranged in front of and behind the carrying unit in the direction of travel or longitudinal direction of the device.
  • the carrying unit can have an articulated arm on both sides facing the driving units, each of which is connected to a further articulated arm of a driving unit via a joint, as a result of which the carrying unit can be displaced in all horizontal directions with respect to the driving units.
  • a lifting device can be arranged between the carrying unit and the driving units, with which the carrying unit can be raised and lowered relative to the driving units.
  • the device should be able to carry out its transport tasks quickly and safely even in tight spaces.
  • the carrying unit can be lowered to the floor of the weaving mill within a certain range of motion, independently of the driving units after having made a precise position with respect to the weaving machine using so-called docking elements.
  • the docking elements are attached on the one hand to extendable arms of the carrying unit and on the other hand are located in certain positions in front of the weaving machine.
  • the transport device can independently drive to a weaving machine, for example, in which the goods tree has to be changed.
  • An exact position of the transport device in relation to the weaving machine does not have to be aimed for when approaching it, so that simple guidance, for example by a wire laid in the ground, which is scanned without contact, is sufficient for steering the transport device.
  • the adjustability of the carrying unit in relation to the driving units enables the carrying unit to be precisely aligned on the weaving machine without the driving units moving and without exertion of force.
  • the functional elements of the support unit consist of gripping elements, bearing elements and auxiliary drives, with which the warp or fabric change is carried out on the weaving machine.
  • the carrying unit rests on the weaving room floor or on docking elements which are assigned to the weaving machine.
  • the driving units are relieved of the load on the carrying unit.
  • the carrying unit becomes rigid again through coupling elements connected to the travel units, so that the load of the entire transport device can be supported on the weaving room floor via wheels of the travel units.
  • Fig. 1 the structure of the transport device is partially shown schematically. It is divided into driving units 1a and 1b and a support unit 2 arranged between them.
  • the travel units each contain a travel drive and support rollers.
  • the carrying unit is drawn with a full goods tree 50, an empty goods tree 51, a winding tree 70, which can be manipulated by gripping arms 40a, 40b. Furthermore, a so-called sword 11 of a cloth folding device and a cutting device 10 are indicated.
  • 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.
  • the transport device 102 between two weaving machines 500a, 500b is shown in FIG. 1a.
  • the yarn is guided from a warp beam 501 via tensioning and deflecting rods 502 to the sley 503, where the weft insertion takes place.
  • the fabric is fed to a fabric tree 50 via a fabric take-off 504 and deflecting rods 505.
  • the parts of the weaving machine mentioned are mounted between cheeks 506, which are held together by tubular cross members 507a, 507b and angular cross members 508a, 508b.
  • the cheeks 506 are supported on foot rails 509.
  • the fabric becomes the fabric tree 50 following the arrow 510 fed and wound on this until a maximum permissible diameter of the cloth wrap on the fabric tree 50 is reached.
  • a logistic control device of the weaving mill then orders the transport device 102 to the relevant weaving machine.
  • the goods tree 50 is removed from the weaving machine 500a by the grippers 40a, 40b and placed in a holder in the transport device 102.
  • the winding tree 70 is then moved from the lower extended position in the transport device to the new, yet empty goods tree 51, the non-cut fabric lying between the goods tree 50 in the transport device and the deflecting rod 505 around the winding tree 70. This is then rolled counterclockwise around the new goods tree 51 by a device, not shown. In the position 70 ′ of the winding tree shown in FIG. 1a, the tissue is cut by a cutting device 10.
  • the free end of the fabric above the cutting device 10 is completely wound onto the fabric tree 51 in a further rolling of the winding tree 70 'on the fabric tree 51.
  • the sword 11 of a cloth folding device is lowered until it lies tangentially on the fabric tree 51 and thus guides the fabric on the fabric tree 51 during winding.
  • a steering device 16 for the drive roller 150 comprises a steering motor 161 which is connected to the drive roller 150 via a toothed belt 162.
  • the steering motor 161 is controlled on the basis of information from a scanning unit 151 which tracks a lane 152 in the floor of the weaving room. If the scanning unit 151 of a position deviating symmetrically to the lane 152, the drive roller 150 is controlled so that the desired position of the scanning unit 151 above the lane 152 is achieved within certain tolerances.
  • the transport device is carried by support rollers 154.
  • a motor 220 can set telescopic tubes 224, 225, 226 in rotation via belt drives 221, 222, 223, which are seated at their respective right ends via ball bushings on telescopic spindles 224 ', 225', 226 '.
  • the transport device 102 can be used for weaving machines or goods trees of different widths.
  • Fig. 3 the drive of the gripping arm 40b and surrounding parts are shown.
  • the gripping arm 40b is driven to rotate about the axis 41 by a motor 402.
  • a motor 403 provides an axial adjustment of the gripping arm in a small frame via the toothing 403 '.
  • the vertical movement of the entire gripper arm 40b is vertically adjusted by a motor 401 and a spindle covered by a spiral spring 401 '.
  • a mechanism for opening and closing the gripper arm is located within a gripper arm 40b.
  • the gripping arm 40b is drawn in the position in which it places the goods tree on pins 52, 52 '.
  • This storage of the goods tree 50 is adjustable in the direction of the axis 41 with the gripping arm 40b when the rollers 53 'move in the region of the guide rod 53.
  • Fig. 3 is the adjustability of the support unit 2 or the side part 20b with respect to the driving unit 1b to see.
  • An articulated bracket 1 ' is articulated on the driving unit 1b, on which a second articulated bracket 2' can be supported.
  • the link plate 2 ' is connected to the side part 20b via a link rod 202.
  • the joint rod 202 also serves as a piston against which the cylinder part 201 can be displaced vertically. The entire carrying unit 2 can thus be moved horizontally and vertically with respect to the driving unit 1b. If, as shown in FIG.
  • the carrying unit is lowered relative to the driving unit 1b, it partially rests on a plate foot 23.
  • the gripping arm 40b sits together with the drives 402 and 403 on a carriage 404 'which is guided vertically by a sliding guide 404 and can be adjusted vertically by means of the drive motor 401.
  • the same arrangement as shown in FIG. 3 is mirrored.
  • Fig. 4 shows the device for lifting and lowering the support unit with respect to the driving unit and the positioning unit for the support unit on a weaving machine.
  • a shaft 283 can be driven via a drive motor 281 and a belt drive 282, with which a spindle 283 'pushes a piston 284' back and forth within a cylinder 284 which is filled with hydraulic oil.
  • the displaced hydraulic oil reaches the cylinder 201 via a line 285, as a result of which the cylinder 201 is lifted vertically relative to the piston 202 and thus the entire support unit 2 relative to the driving unit 1b.
  • bolts 26 'and 27' can also be seen, which are seated in the side part 20b and in the cylinder part 201 and, when the support unit 2 moves vertically relative to the driving unit 1b, move on the driving unit 1b within the scenes 26 and 27. While the scenes 26 and 27 guide the bolts 26 'and 27' exactly in the upper part, they give them enough leeway in their lower part
  • the treg unit 2 can move relative to the driving unit 1b during the positioning process.
  • the mobility of the support unit 2 relative to the driving unit 1b is made possible as described above by the articulated mounting 1 ', 2'.
  • the driving units are stopped after the transport device 102 approaches a weaving machine 500, whereupon supports 30a and 30b are moved out of the foot of the side part 20a and 20b with the aid of the drive 31.
  • the support unit 2 is lowered relative to the driving units 1a and 1b as described until the feet 24 and 25 come into contact with the cone 24 'and the prism 25'.
  • the exact positioning of the support unit 2 in front of a weaving machine 500a is achieved by centering the funnel foot 24 on the cone 24 'or the prism foot 25 on the prism 25'.
  • the extended supports 30a and 30b increase the stability of the transport device.
