Definitions

  • the present invention relates to a false twist texturing machine. More specifically, the present invention relates to a false twist texturing machine for synthetic yarn comprising a creel for supporting supply package, a first feed roller means for feeding a yarn withdrawn from the supply package on the creel, a heater for heat set the yarn fed by the first feed roller means, a cooling plate for cooling the yarn heated by the heater and for advancing the yarn stably, a false twisting device for twisting the yarn leaving from the cooling plate, a second feed roller means for forwarding the false twisted yarn, and a take-up means for winding the yarn forwarded from the second feed roller means to a yarn package, whereby the take-up means is arranged by the creel sandwiching an operator's aisle therebetween, known, for instance, from document EP-A-0 469 763.
  • the present invention is not limited to but is especially suitable for a false twist texturing machine for false twisting a nylon yarn having small denier which is used for stockings or panty hose.
  • the false texturing machine of the present invention may be a draw texturing machine, wherein the yarn Y is drawn at a predetermined draw ratio before or while it is imparted with twists by the false twisting device.
  • a thin synthetic yarn i.e., a synthetic yarn having a small denier, such as a nylon yarn used for stockings or panty hose
  • a single heater is used since especial control of bulk properties or stretch properties of the yarn is not required.
  • the yarn withdrawn from the creel by means of a first feed roller means is subjected to a false twisting operation by means of a false twisting device. Twists run back along the yarn from the false twisting device toward the upstream direction and are heat set by means of a heater disposed upstream the false twisting device.
  • the false twisted yarn leaving the false twisting device is fed to a take-up device by means of a second feed roller means, and the yarn is wound into a yarn package by means of the take-up device.
  • the yarn take-up devices are arranged at the opposite sides of a machine frame, the second feed roller means and the false twisting devices are disposed at the top of the winding portions of the take-up devices, the first feed roller means are disposed facing the take-up devices having operator's aisles therebetween, the creels constructed in four or six rows are stationary arranged below the first feed roller means in such a manner that they faces the take-up devices, respectively, sandwiching the operator's aisles therebetween, and the heaters are arranged from positions above the first feed roller means to the second feed roller means (for example, Japanese Patent Publication No. Sho 55-31213).
  • the take-up devices which have been arranged at the opposite sides of a machine frame in the above-mentioned Japanese Patent Publication No. Sho 55-31213, are separated from each other having an operator's aisle therebetween, and the creels are also separated from each other corresponding to the respective take-up devices, and a heater extending above and over the two take-up devices and two creels (see Japanese Patent Application Laid-open No. Sho 57-11222).
  • the take-up devices are arranged at the opposite sides of a machine frame as disclosed in Japanese Patent Publication No. Sho 55-31213, upon doffing of full packages wound on the take-up device, the full package has to be taken up toward the operator's aisle and then to be loaded manually, or in some case, automatically by means of a doffing apparatus, to a transfer truck located near the take-up device, and the transfer truck has to be moved to the outside of the texturing machine.
  • the transferring operation has to be done together with the doffing operation of the full packages, and accordingly, the time schedule for operators become very complicated.
  • the doffing and transferring operations have to be concentrated in a short time, and labor consumption is very large.
  • a false twist texturing machine for synthetic yarn comprising a creel for supporting supply package, a first feed roller means for feeding a yarn withdrawn from the supply package on the creel, a heater for heat setting the yarn fed by the first feed roller means, a cooling plate for cooling the yarn heated by the heater and for advancing the yarn stably, a false twisting device for twisting the yarn leaving from the cooling plate, a second feed roller means for forwarding the false twisted yarn, and a take-up means for winding the yarn forwarded from the second feed roller means to a yarn package, whereby the take-up means is arranged by the creel sandwiching an operator's aisle therebetween, characterized in that
  • the height of the creel per se can be reduced. Accordingly, an operator can perform the operation for supplying packages to the creel from the operator's aisle. Therefore, an especially large creel truck with steps for supplying packages is unnecessary, and operation efficiency becomes good.
  • the first feed roller means is disposed above the rotary creel.
  • the yarn is not bent excessively while it is withdrawn from the central top of the rotary creel to the first feed roller means. Accordingly, the tension in the yarn is reduced, and the variation in the yarn tension is also reduced.
  • the heater and the cooling plate is arranged in a substantially straight line while they are inclined downwardly, there is no substantial deflection between the cooling plate and the heater.
  • the running back of the twists imparted by the false twisting device is not prevented, and unevenness in the twists is prevented from occurring.
  • the heater is a high temperature heater of a non contact type, which is heated to a temperature higher than a melting point of the yarn, for example, more than 300 o C, and which heat sets the yarn under a condition substantially without contacting with the yarn.
  • the length of the heater can be shortened to about 1 m, and this contributes to the reduction of the machine height.
  • a cradle turning device may be provided for discharging the package wound on the take-up device to a position opposite to the operator's aisle. If it is the case, the wound package can be temporarily stored at a package stocker which is disposed at a position opposite to the operator's aisle upon doffing operation, and then the full packages may be gradually collected after the doffing operation is completed.
  • the time schedule for an operator can be set with ample time, and since the various operations by the operator can be distributed, the number of the operators can be reduced. If it is desired, the full package may be collected from the package stocker. It is expected that automation can be done readily if the full packages are collected from the package stockers.
  • reference numeral 10 denotes a rotary creel. More specifically, the creel 10 is turnable about a vertical spindle 11, and the creel 10 is supported by the spindle 11 and the bracket 13 located above the creel 10.
  • the creel 10 has a plurality of pegs 12 for mounting supply packages.
  • yarns withdrawn from the supply packages mounted on the creel 10 are taken out upwardly from the center.
  • the yarn Y withdrawn from the creel 10 is taken up by a first feed roller means 20 disposed above the creel 10 and fed to a heater 30 for heat setting.
  • the heat setting heater 30 is of non contact type, and is heated to a temperature higher than a melting point of the yarn Y, for example, a temperature higher than 300 o C, and it heats the yarn in a substantially non contacting state.
  • a cooling plate 40 is arranged in such a manner that the cooling plate 40 and the heater 30 are aligned in a substantially straight line.
  • the yarn passing through the heater 30 and the cooling plate 40 is not subjected to a large bending operation there, i.e., it is guided along a substantially straight line, and enters into a false twisting device 50.
  • the false twisting device 50 may be constructed with multiple spindles and multiple discs attached thereto or a rotary spindle with a twisting pin.
  • a take-up device 70 is disposed at the downstream of the false twisting device 50.
  • a second feed roller means 60 is disposed above the take-up device 70.
  • the yarn Y is drawn at a predetermined draw ratio before or while it is imparted with twists by the false twisting device.
  • the false texturing machine of the present invention constitutes a draw texturing machine.
  • the yarn Y fed from the second feed roller device 60 is wound in the take-up device 70.
  • the rotary creel 10 and the take-up device 70 face to each other via an operator's aisle 90 sandwiched therebetween.
  • the operator's aisle 90 is a place where an operator stands when a threading operation to the take-up device 70 is carried out by the operator.
  • the take-up device 70 comprises a traverse device for traversing the yarn Y, cradles 72 for supporting a wound package, and a drive roller 73, being in contact with a bobbin supported by the cradles 72 or a yarn layer wound on the bobbin, for driving the bobbin at a predetermined speed, and the construction itself has been well known.
  • Cradle arms 72 of the take-up device 70 are so constructed that they make the bobbin contact with a drive roller 73 under the winding condition and that they turn to a position opposite to the operator's aisle 90, i.e., to the left in the illustrated embodiment, after completion of the winding operation so that the full packages are doffed onto the package stockers 80 disposed correspondingly to the winding stations of the take-up device 70.
  • the yarn Y is withdrawn from the supply package which is mounted on the peg 12 of the rotary creel 10 and is taken up by the first feed roller means 20 which is disposed above the rotary creel 10, and then, the yarn is fed to the heater 30.
  • the yarn Y passes through the heater 30 and the cooling plate 40, and then it reaches the false twisting device 50, where twists are imparted to the yarn Y.
  • the twists imparted to the yarn Y run back along the yarn Y toward the heater 30, where they are heat set.
  • the yarn Y heated by the heater 30 is cooled by the cooling plate 40, and enters into the false twisting device 50. Leaving the false twisting device 50, the yarn Y is de-twisted.
  • the thus obtained false twisted yarn is fed to the take-up device 70 by means of the second feed roller device 60, and the yarn is traversed by a traverse device 71 in the take-up device 70 and is wound on a bobbin which is driven by the drive roller 73 to form a yarn package.
  • the cradles 72 are turned to a position opposite to the operator's aisle 90, and the package is discharged on the package stocker 80.
