[Prior art]
Conventionally, textiles with patterns are roughly classified into pre-dyed products that have been woven using already-dyed warp and weft yarns, and post-dyed products that are dyed after weaving. In the case of woven fabrics that are woven in the cocoon pattern, that is, a cocoon pattern that looks hazy in some places, they are woven using dyed yarn.
[0003]
The conventional method for dyeing a leopard pattern on the weft yarn using the dyed yarn as described above is to make a seed yarn that will be used as a measure of the portion of the weft yarn that will not be dyed. There is a tie-dye pattern dyeing method in which, using this seed yarn, a portion of the weft yarn that is not dyed is bundled with cotton yarn to prevent dyeing, and then this is dyed by dyeing in a dye solution. On the other hand, there is a so-called rubbing leopard pattern dyeing method in which a dye is rubbed into a portion to be dyed, and there is a method of drawing a leopard pattern by molding.
[0004]
Further, a colorful printed silk tone spun yarn is also known in which different color portions formed from at least two types of fibers having different colors with respect to the longitudinal direction of the yarn are randomly arranged. (For example, see Patent Document 1)

[0021]
A method for producing a special kite string according to the present invention will be described with reference to FIG. The yarns Y1, Y2, and Y3 are pulled out from the packages P1, P2, and P3 mounted on the creel 10 and inserted through the tension applying member 11, and pass through the yarn selecting device 20, the yarn joining device 12, and the yarn length measuring storage device 30. In the drawing, a special yarn winding package PW is manufactured by the winding drum 14 via the second tension applying member 13. Reference numeral 15 denotes a cradle that supports the yarn supply package PW.
[0022]
The packages P1, P2, and P3 are packages having different colors and yarn types, and are continuously supplied to the yarn length measurement storage device 30 while being spliced by the yarn splicing device 12. Further, packages of color types and yarn types necessary for forming a special kite winding package PW are mounted on the creel 10, and are not limited to the three illustrated, but six or twelve There is no limit on the quantity because it may be installed.
[0023]
The yarn selecting device 20 has yarn guides 21a, 21b, and 21c (see FIG. 3) arranged for the packages P1, P2, and P3, respectively, and guides the yarn Y to the yarn joining device 12 as will be described later. It is configured to be movably controlled to a yarn guide position (corresponding to 21A in the figure) and a position for guiding the yarn Y to the suction member 16 (corresponding to 21B in the figure).
[0024]
The yarn joining device 12 cuts and joins the yarn Y, and the yarn selected by the yarn selecting device 20 is guided by the guide guide 26 shown in FIG. It is configured. As the yarn splicing device 12 may be a splicing device for piecing by air vortex, or in the knotter device for performing knotting. Whether to adopt a splicer device or a knotter device is selected depending on the type of yarn to be used and the required yarn joining mode.
[0025]
The yarn selection device 20 will be described in detail with reference to FIGS. As the yarn guide 21, a yarn guide 21a that guides the yarn Y1, a yarn guide 21b that guides the yarn Y2, a yarn guide 21c that guides the yarn Y3, and the like are arranged by the cylinder 27. By swinging the member 28 with the fulcrum 28a as the center of rotation, the push-up bar 28b disposed at the other end of the swing member 28 comes into contact with the rear guide plate 22B of the thread guide 21 and swings the thread guide 21. The yarn guide position is such that the yarn Y is guided to the yarn joining device 12 (corresponding to 21A in the drawing) and the position where the yarn Y is guided to the suction member 16 (corresponding to 21B in the drawing).
[0026]
The yarn guide 21 has a boss portion 22 and is configured to be rotatable around a rotation shaft 22A. The boss portion 22 is provided with a rear guide plate 22B extending rearward. The yarn guide 21 guides the yarn Y to the yarn joining device 12 by a spring member 23 attached to the rear guide plate 22B. It is configured to bias in the direction of the guide position (corresponding to 21A in the figure).
[0027]
The yarn Y sucked by the suction member 16 is sandwiched between the yarn holding roller 17 and the yarn holding plate 18. The yarn holding roller 17 is a roller member whose outer peripheral surface is coated with an elastic material such as urethane, and the yarn holding plate 18 is configured to abut against and separate from the yarn holding roller 17 by a cylinder 19.
[0028]
When the yarn guide 21 is swinging during the selection of the yarn, the yarn holding plate 18 is separated from the yarn holding roller 17 so that the suction member 16 can suck the yarn Y. When a predetermined yarn is selected and a predetermined yarn guide 21 is positioned at 21A, the yarn holding plate 18 is brought into contact with the yarn holding roller 17 by the cylinder 19 to hold the yarn Y sucked by the suction member 16. Has been.
[0029]
The rear guide plate 22B has a configuration in which a notch is formed at the rear end thereof and the locking piece 24 is locked, and the cylinder 27 guides the yarn guide 21 to the suction member 16 through the push-up bar 28b. When pressed down (corresponding to 21B in the figure), the cylinder 25 causes the locking piece 4 to lock into the notch at the rear end of the rear guide plate 22B, so that the position of the thread guide 21 is brought to the position of 21B in the figure. It is to be fixed. The locking piece 24 is configured to be rotatable by a cylinder 25 with a fulcrum 24A as a rotation center.
[0030]
In the thread switching method, first, the cylinder 27 is slightly extended and the rear guide plate 22B is lifted to release the engagement state with the locking piece 24. Next, only the cylinder 25 corresponding to the selected thread type is driven to move the locking piece 24, so that the locking piece 24 does not come into contact regardless of the position of the rear guide plate 22B. Thereafter, when the cylinder 27 is contracted and the thread guide 21 is rotated by the spring member 23, only the locking piece 24 corresponding to the selected thread type is in a position where it does not engage with the rear guide plate 22B. The yarn guide 21 corresponding to the selected yarn type moves to the yarn guide position (corresponding to 21A in the figure) for guiding the yarn Y to the yarn joining device 12, and the other yarn guide 21 has the locking piece 4 at the rear portion. It is configured to engage with the guide plate 22B and stop at the guide position 21B in the figure.
[0031]
The yarn inserted through the selected yarn guide 21 is in a state where one end thereof is held by the suction member 16, and is indicated by YA indicated by a broken line. The yarn YA is guided in the direction of the yarn splicing device 12 by turning the guide guide 26 in the direction of the arrow in the drawing, and the yarn YA is spliced with the yarn Y that has been wound around the winding yarn package PW so far and starts winding. It is configured to
[0032]
At this time, the number of selected yarns is not limited to one, and two yarns (for example, yarns Y1 and Y2) may be simultaneously selected and spliced .
[0033]
The yarn length measurement storage device 30 will be described with reference to FIG. When the yarn length measurement storage device 30 is driven and winding is started, the yarn Y having a predetermined length is stored in the storage drum 33. A rotating shaft 32 having a yarn passage 32b along the central axis inside the apparatus main body 31 is rotationally driven by a pulse motor 37 (or a servo motor capable of angle control). The pulley 34 mounted on the rotating shaft 32 is driven to rotate via the pulley 36 and the driving belt 35 disposed in the pulse motor 37, whereby the rotating shaft 32 is rotated and branched from the rotating shaft 32. The winding tube 32 a is configured to turn around the storage drum 33.
[0034]
When the winding tube 32a is driven to rotate around the storage drum 33, the yarn Y inserted through the yarn passage 32b disposed so as to penetrate the winding tube 32a from the central shaft portion of the rotating shaft 32 is Is wound around and stored in a storage drum 33 formed in a tapered shape with a slightly reduced diameter in the traveling direction. Since the yarn Y that has come out of the winding tube 32a is wound around the outer diameter portion of the tapered portion of the storage drum 33, the yarn Y moves toward the front that is slightly reduced in diameter by sliding along the tapered portion. When the yarn Y is wound around the storage drum 33 while the winding tube 32a rotates, the yarn sliding action is continuously performed. Therefore, the yarn Y extends over substantially the entire outer diameter of the tapered portion of the storage drum. Are stored in a state of being arranged in a spiral.
[0035]
The selected yarn length is controlled by controlling the rotation angle of the pulse motor 37 (or a servo motor capable of controlling the angle) by a control device (not shown). Therefore, it is possible to control the length of minute dimensions (1 cm or less). In conjunction with the rotation angle of the pulse motor 37 driven by a control program determined in consideration of the pattern after weaving (corresponding to the yarn length determined in consideration of the pattern after weaving), Since the winding tube 32a rotates by a predetermined angle, the yarn length wound around the storage drum 33 and stored is accurately controlled to the yarn length that forms the pattern after weaving. The presence of the yarn Y stored in the storage drum 33 is performed by a detection sensor such as a photoelectric sensor. In the present embodiment, a leading end detection sensor 39a and a rear end detection sensor 39b are provided.
[0036]
When winding of the yarn Y around the storage drum 33 is started and the leading portion detection sensor 39a detects the yarn Y, the rotational drive of the winding tube 32a is temporarily stopped. When the winding operation is continued in a state where the winding of the yarn Y around the storage drum 33 is stopped and the storage is interrupted, the yarn gradually decreases from the storage drum 33, and the yarn Y is detected by the rear end detection sensor 39b. Therefore, the pulse motor 37 is driven again and the winding by the yarn length measuring storage device 30 is resumed. When the winding is resumed, the wound yarn Y is wound while moving forward toward the slightly reduced diameter so as to slide on the tapered outer diameter portion of the storage drum 33, so that the entire length of the storage portion is again The leading end detection sensor 39a detects the yarn Y.
[0037]
The speed at which the winding tube 32a is rotated and the yarn Y is stored is higher than the speed at which the winding drum 14 winds up the wound package PW. This absorbs an error between the winding speed of the yarn Y wound by the rotation of the winding drum 14 and the storage speed, and takes into consideration the time for selecting the yarn and the time for splicing. In this configuration, the yarn is stored quickly, so that the winding operation can be continued even while the yarn storage is stopped, the yarn is selected and the yarn is joined.
[0038]
FIG. 5 shows a special bobbin winding package PW. The package PW is a package in which various colored yarns of the yarns Y1, Y2, Y3,... Are wound in a predetermined order and with a predetermined length to be wound as a single yarn Y. Therefore, as shown in FIG. 5B, a yarn Y having a color distribution such as a red thread having a length L1, a yellow thread having a length L2, a blue thread having a length L3, and a black thread having a length L4 is obtained. be able to. Further, the arrangement is not limited to the color of the yarn, and the arrangement may be such that the thickness of the yarn and the number of components (single yarn, twin yarn, triplet yarn, etc.) are changed. Furthermore, the thread types can be changed and arranged.
[0039]
According to the present invention, when at least one yarn is selected from a plurality of packages and continuously spliced , a plurality of yarns are simultaneously selected and spliced so that the constituent ratio of the yarn in the longitudinal direction is increased. Since the yarn having the replaced arrangement portion is produced, a special kite yarn having the arrangement portion that correctly represents the pattern after weaving can be produced. In addition, a special yarn winding package that can produce a woven fabric or a knitted fabric having a predetermined pattern by winding each array portion to a predetermined length while measuring the length. Can be obtained.
