Definitions

  • the present invention relates to a sample warper with an idle running preventing mechanism of a yarn guide which has a plurality of yarn guides for winding yarns on a warper drum and automatically exchanges yarns in a preset yarn order to wind the yarns on the warper drum, wherein yarns to be wound can be very effectively exchanged by utilizing the plural yarn guides, and a high speed warping method.
  • the fixed creel has a plurality of bobbins on which the same kind and/or different kinds (mainly different kinds) of yarns are to be wound, wherein since yarns can be warped for each yarn while yarn exchanging is freely performed by the selection device, a warping operation for pattern warping can be advantageously performed, but since yarns are sequentially wound on the warper drum for each yarn, much time is disadvantageously required for a warping operation.
  • the rotary creel has a plurality of bobbins on which the same kind and/or different kinds of yarns are to be wound, and it can be applied to repetition warping for an extremely limited number of patterns such as solid color warping (for example, one color of a red color yarn), one to one warping (for example, repetition of one red yarn and one white yarn, or repetition of one S-twisted yarn and one Z-twisted yarn), two to two warping (for example, repetition of two red yarns and two white yarns, or two S-twisted yarns and two Z-twisted yarns) and the like.
  • a warping operation for pattern warping except for the extremely limited number of patterns can not be disadvantageously performed but a warping time can be advantageously reduced to a great extent because the plural yarns are wound on the warper drum simultaneously.
  • the present applicant has already proposed a sample warper provided with a plurality of yarn selection devices corresponding to a fixed creel and a rotary creel, which can perform jointly pattern warping and repetition warping and reduce a warping time of a warping operation requiring solid color warping and pattern warping to achieve an extremely high efficiency (refer to JP2000-136456A and EP933455A2).
  • the present applicant has also proposed a novel yarn removing mechanism that can prevent a yarn from loosing in the above-described sample warper to perform yarn exchanging efficiently (refer to JP11-293536A, EP955399A2 and US Patent 5,970,591).
  • yarn exchanging using a fixed creel in a current sample warper that is, feeding a yarn from a yarn selection guide to a yarn guide, or storing a yarn from the yarn guide to the yarn selection guide
  • yarn exchanging using a fixed creel in a current sample warper has been performed by using one yarn guide in a sample warper having one yarn guide, or by selecting one yarn guide to be used in a sample warper having a plurality of yarn guides.
  • a yarn guide when yarn exchanging is performed from a red yarn to a white yarn, a yarn guide must perform idle running of at least one rotation between storing of a yarn and feeding of another yarn in order that the red yarn is removed from the yarn guide to store the removed red yarn in a yarn selection guide for the red yarn and the white yarn is fed from a selection guide for the white yarn to the yarn guide.
  • the present inventors have solved the above-described problem and have reached to the present invention as a result of the repeated research about a mechanism for reducing the idle running time of the yarn guide during yarn exchanging to the least possible level.
  • a first object of the present invention is to provide a sample warper with an idle running preventing mechanism of a yarn guide which can reduce an idle running time during yarn exchanging to the least possible level so as to improve a speed of yarn exchanging remarkably and hence can shorten a warping time largely as compared with a case of using a conventional yarn exchanging mechanism where an idle running is performed.
  • a second object of the present invention is to provide a high speed warping method which realizes a sharp increase in warping rate and can reduce an idle running time of a yarn guide to the least possible to perform yarn exchanging while maintaining a high warping rate, that is, without lowering the warping rate, thereby reducing the warping time considerably.
  • a sample warper with an idle running preventing mechanism of a yarn guide comprising: a plurality of yarn guides each rotatably mounted on a side surface of a warper drum for winding yarns on the warper drum; a yarn selection device provided with a plurality of yarn selection guides which are in correspondence with the yarn guides, each of the yarn selection guides being pivotally moved to project to a yarn exchanging position when exchanging yarns and retract to a standby position when storing yarns; a fixed creel for supporting a plurality of bobbins on which the same kind and/or different kinds of yarns are to be wound and which are in correspondence with the plural yarn selection guides; and yarn removing guides which are provided such that one of the yarn removing guides corresponds to each of the plural yarn selection guide, wherein yarns are automatically exchanged and successively wound on the warper drum according to a preset yarn order by passing the yarns between the yarn guides and the yarn selection guides, and where
