Definitions

  • the present invention relates to an apparatus for moving bobbins and tubes for a textile plant, and a textile plant comprising such apparatus for moving bobbins and tubes.
  • the Multilink type textile plants comprise a plurality of spinning machines which feed a winding machine, and a transport system for the bobbins for sending the bobbins from a spinning machine to the winding machine, and a transport system for the empty tubes arriving from the winding machine and destined for a specific spinning machine.
  • These systems provide a plate, arranged with a protruding portion, called collar, suitable for being partially inserted into a tube.
  • the plate is guided by the transport system which essentially comprises a conveyor belt on which the plate is placed, and a guide suitable for coupling with the portion of the collar which is not contained inside the tube.
  • the guide may be made, for example, by means of two portions of sheet metal placed side by side but spaced apart, in such a way as to identify a slot just wider than the diameter of the collar.
  • the spinning machines are arranged parallel, with one end aligned, so that they may face a single shared transport system.
  • the shared transport system is substantially composed of two conveyor belts, onto which the empty bobbins or tubes are loaded automatically.
  • a first conveyor belt takes care of transporting the bobbins from the respective spinning machine to the winding machine, and a second conveyor belt takes care of transporting the empty tubes from the winding machine to the destination spinning machine.
  • conveyor belt or conveyor we mean a system suitable for transporting the bobbins from one position to another.
  • the conveyors may be of the type indicated above, and may comprise lanes on which the plates may be inserted, and a movable element such as a belt or a chain suitable for moving the plates from one position to another.
  • the tube thus freed is positioned on the shared transport system and sent to the destination spinning machine.
  • thread or monofilament or continuous thread means a single filament or continuous strand (for example in the case of silk, artificial, or synthetic fibers), while the term “yarn” means the set of fibrils of variable length that are parallelized and joined by twisting. In the following, either term will be used indistinctly, it being understood that the applications of the present invention are not limited to one or the other type.
  • Each bobbin in order to be assigned correctly, is associated with a plate, on which a tracking device is generally placed which allows said plate and therefore the relative bobbin or tube to be associated to a specific winding unit or to a specific spinning machine.
  • Figure 1 schematically shows an apparatus 12 for moving bobbins and tubes in a textile plant 14 essentially comprising at least one group of at least two spinning machines 100; 200 and at least one winding machine 300.
  • the apparatus 12 comprises an outward conveyor 102; 202, and a return conveyor 104; 204 for each spinning machine 100; 200, wherein the outward conveyor 102; 202 is adapted for transporting bobbins in output from the respective spinning machine 100, 200; and the return conveyor 104, 204 is adapted for transporting tubes entering the respective spinning machine 100, 200.
  • the apparatus comprises a sorting device 400, which comprises a conveyor station 402 at which the outward conveyors 102; 202 converge, and a redistribution station 404 at which the return conveyors 104; 204 converge.
  • a sorting device 400 which comprises a conveyor station 402 at which the outward conveyors 102; 202 converge, and a redistribution station 404 at which the return conveyors 104; 204 converge.
  • the conveyor station 402 and the redistribution station 404 are connected by means of a conveyor 406 and a redistribution conveyor 408, respectively, to a bobbin input line 302 to the at least one winding machine 300 and to a bobbin output line 304 from the at least one winding machine 300.
  • the conveyor station 406 and the redistribution station 408 are adapted for redistributing the bobbins or tubes respectively to the conveyor 406 or to the return conveyors 104; 204 based on predetermined operating parameters of the bobbins and tubes to be redistributed.
  • the spinning machines 100; 200 may be substantially aligned with each other.
  • substantially aligned spinning machines means that the respective spinning heads of the spinning machines are substantially aligned with each other. In other words, the spinning machines are aligned with each other in a direction longitudinal to them.
  • the outward 102 and return 104 conveyors of the spinning machine 100 placed in proximity to said sorting device 400 may be arranged internally with respect to the outward 202 and return 204 conveyors of the spinning machine 200 distal with respect to the sorting device 400.
  • outward conveyors 102, 202 and the return conveyors 104, 204 may be arranged substantially parallel to each other.
  • the spinning machines 100, 200 may have 300-600 heads.
  • FIG. 2 shows an alternative embodiment of the apparatus of the present invention.
  • At least one further spinning machine 250 may be arranged downstream of the sorting device 400, i.e. between the sorting device 400 and the at least one winding machine 300.
  • the apparatus 14 therefore comprises an outward conveyor 252 and a return conveyor 254 for the at least one further spinning machine 250.

  • the second sorting device 401 may be entirely similar to the sorting device 400.
  • the conveyor station 403 and the redistribution station 405 of the second sorting device 401 are connected by means of a conveyor 407 and a redistribution conveyor 409, respectively, to a bobbin input line 302 to the at least one winding machine 300 and to a bobbin output line 304 from the at least one winding machine 300.
  • the conveyor station 402 of the sorting device 400 may comprise a conveyor disc 410.
  • the redistribution station 404 may also comprise a redistribution disc 412.
  • the conveyor disc 410 and the redistribution disc 412 comprise at least one side seat 414, 416 adapted to engage a collar of a plate of a bobbin, and by rotating they move the plate from an input position to the relative station 402, 404 and an output position from the station 402, 404.
  • the rotation of the conveyor disc 410 and of the redistribution disc 412 may take place in a manner known per se to those skilled in the art, for example through an actuator (not shown) operated by the central control unit 500 of the textile plant, or through a dedicated control unit (not shown).
  • the conveyor disc 410 and/or the redistribution disc 412 may comprise six side seats 414, 416, as shown in the examples of Figures 4-7 .
  • the conveyor disc 410 and/or the redistribution disc 412 may comprise three side seats 414, 416.
  • the side seats 414, 416 are adapted to be engaged by a collar of a plate, so as to be able to be repositioned through a rotation of the conveyor disc 410 or of the redistribution disc 412.
  • the disc with six side seats 414, 416 may be adapted to rotate in one direction only.
  • control unit 500 of the textile plant may be adapted to manage these rotations, so that they are, for example, as short as possible, in terms of time or displacement.
  • the conveyor station 402 and the redistribution station 404 may be of different types in the same sorting device 400.
  • the conveyor station 402 may be provided at each outward conveyor 102, 202 with stops 209, 211 adapted to selectively block a plate.
  • Said stops 209, 211 may be of a mechanical type, electrically or pneumatically actuated. In any case, said stops 209, 211 may be of a type known per se to those skilled in the art and therefore will not be further explored.
  • the redistribution station 404 may comprise a diverter 213 adapted to divert the plates arriving from the winding machine to one of the return conveyors 104, 204.
  • the diverter 213 may be, for example, of a mechanical type, and electrically or pneumatically operated. In any case, the diverter 213 may be of a type known per se to those skilled in the art and therefore will not be further described.
  • a stop 203 may be provided on the outward conveyor 202 of the most distant spinning machine 200.
  • Such stop 203 is suitable for preventing jams being created in proximity to the sorting disc and, at the same time, uses the same outward conveyor 202, which is longer, as a temporary storage system for the bobbins.
  • the stop 203 may be of the pneumatic type.
  • the stop 203 may be managed directly by the control unit 500.
  • the return conveyor 104 of the spinning machine 100 closest to the sorting station 400 may be provided with a bypass conveyor 105 adapted to directly connect the return conveyor 104 to the outward conveyor 102 of the spinning machine 100.
  • a diverter 107 is arranged in the vicinity of the fork between return conveyor 104 and bypass conveyor 105 suitable to divert the plates towards the return conveyor 104, or towards the bypass conveyor 105.
  • the diverter 107 may be of a type known per se to those skilled in the art and therefore will not be further described.
  • the operation of the bypass conveyor 105 provides that in the event that the spinning machine closest to the sorting station 400 is not able to receive empty tubes, these are sent to the conveyor station 402 to be sent back to the winding machine 300.
  • the winding machine 300 detecting the presence of an empty tube, will send it back to the spinning machine.
  • the process may be repeated until the spinning machine returns to operate to receive a tube.
  • the winding machine will recirculate the empty tubes inside the winding machine itself until the spinning machine returns to operate.
  • overflow sensors 205, 207 may be arranged, adapted to detect the presence of spools and to send this information to the central control unit 500 to stop the feeding of the bobbins to the relative conveyors, if necessary.
