Description

  The present invention relates to a sample warper and a sample warping method used for warp sample warping, and more particularly to a sample warper and a sample warping method using a rotary creel, and a rotation used therefor. It relates to the expression creel.

  Conventional sample warpers are roughly classified into a method using a fixed creel, a method using a rotary creel, and a method using both a fixed creel and a rotary creel.

  The fixed creel method uses a fixed creel that stands up a plurality of bobbins wound with different types of yarn (different colors or different twists), and the yarn is selected by a yarn selection guide according to preset pattern data (yarn order). A yarn is wound around a warping drum by a yarn guide while exchanging (for example, see Patent Document 1 and Patent Document 2). The fixed creel has a plurality of bobbins wound with the same type and / or different types of yarns (mainly different types of yarns), and can warp one yarn at a time. Although there is an advantage that the warping work can be performed, there is a disadvantage that it takes much time for the warping work to sequentially wind one yarn around the warping drum.

  In addition, the method using a rotary creel uses a rotary creel and omits the yarn changing process, eliminates time loss during yarn replacement, and allows multiple yarns to be wound around a warping drum at the same time. Furthermore, the warping work time can be shortened. A conventional sample warping machine using a rotary creel will be described with reference to FIG. 8. In FIG. 8, reference numeral 200 denotes a conventional rotary creel type sample warping machine. The basic structure includes a substantially cylindrical warping drum 214 (for example, a drum outer peripheral length of 7 m) and a base 212 that supports the warping drum 214, and the outer periphery of the warping drum 214 is arranged in the longitudinal direction thereof. A plurality of movable conveyor belts 217 are provided, and on both sides of the warping drum 214, weaving bars 218a to 218g which are weaving means for forming a predetermined weave in the longitudinal direction are provided. A plurality of (eight in the illustrated example) yarn guides 206 a are provided on the front surface of the warping drum 214 so as to be rotatable about the drum axis of the warping drum 214 and wind the warp Y on the outer peripheral surface of the warping drum 214. ~ 206h are provided. Further, the sample warper 200 is arranged on the front outer side corresponding to the yarn guides 206a to 206h, a plurality of bobbins B are detachably mounted, and the rotation of the yarn guides 206a to 206h is electrically or mechanically. The rotary creel 230 is operated synchronously. Then, the warp Y is wound around the outer peripheral surface of the warping drum 214 while the rotation of the yarn guides 206a to 206h and the rotary creel 230 are synchronously operated, and the warp Y is continuously warped in a multiple number. (See Patent Document 3 and Patent Document 4).

  In such a rotary creel type sample warper, the rotary creel has a plurality of bobbins wound with the same type and / or different types of yarns, and has a plain warp (for example, one red yarn), 1 to 1 pattern warping (for example, 1 red and 1 white repeat, 1 S twist and 1 Z repeat), 2 to 2 pattern warping (eg 2 red and 2 white) Can be used only for warping of a very limited pattern such as 2 repetitions, 2 repetitions of S twist and 2 repetitions of Z twist). The rotary creel type sample warper has the disadvantage that it cannot perform the warping work of the pattern warp other than the warping of the limited design, but winds multiple yarns around the warping drum at the same time. Therefore, there is an advantage that the warping work time is greatly shortened.

In addition, there is Patent Document 5 as a method of using a fixed creel and a rotating creel together, and Patent Document 6 as a method of combining a plurality of rotating creels.
Japanese Patent No. 1529104 Japanese Patent No. 2854789 Japanese Patent No. 1767706 Japanese Patent No. 3420526 Japanese Patent No. 3418562 JP 2002-339183 A JP 2004-156185 A

  The present invention has been made in view of the above problems, and has the disadvantage that it takes a long time for the warping work of the method using the fixed creel and the warping of the limited pattern of the method using the rotating creel. A new sample warping machine, sample warping method and rotary creel that can eliminate the disadvantage of being impossible at the same time, in other words, warp in a very short time without limiting warping design. Is intended to provide.

  In order to solve the above-mentioned problems, the present inventors have intensively studied. As a result, the rotary creel is provided with a yarn joining mechanism, and the yarn joining mechanism according to preset pattern data (yarn order) has a predetermined length in the longitudinal direction of the warp. If the warp length is changed to a different color or different warp for each warp length, simultaneous warping of a plurality of yarns is not required, and there is no need to change the warp with a yarn select guide, and there is no restriction on the warp design. It has been found that warping can be made possible. Since there is no need to change the yarn during the warping operation, it is possible to eliminate any trouble that has occurred at the time of changing the yarn, and if the yarn guide is integrated with the rotary creel, The trouble for synchronously rotating the rotation of the rotary creel can be eliminated.

  That is, the first aspect of the sample warping machine of the present invention includes a warping drum, a plurality of conveyor belts movably provided in the longitudinal direction of the outer peripheral portion of the warping drum, and the warping drum side. A weaving means which is provided in the longitudinal direction of the section and forms a predetermined twill, and is arranged in front of the warping drum, and is provided with one or a plurality of yarn joining mechanisms, and a plurality of yarn joining mechanisms corresponding to the yarn joining mechanisms. A rotary creel having a bobbin detachably attached thereto, and a plurality of yarns fixed to ends of the rotary creel opposite to the front surface of the warping drum and winding warp on the outer peripheral surface of the warping drum A guide is provided, and a plurality of warps are simultaneously warped while being replaced with different or different warps for each predetermined warping length in the longitudinal direction of the warp.

  A second aspect of the sample warping machine of the present invention includes a warping drum, a plurality of conveyor belts provided movably in the longitudinal direction of the outer peripheral portion of the warping drum, and a side portion of the warping drum. A weaving means which is provided in the longitudinal direction and forms a predetermined twill; and a plurality of yarns which are rotatably supported around the drum axis on the front surface of the warping drum and wind warp on the outer peripheral surface of the warping drum A guide and one or more yarn splicing mechanisms are provided in front of the yarn guide, and a plurality of bobbins are detachably mounted corresponding to the yarn splicing mechanism, and are synchronized with the rotation of the yarn guide. A rotary creel that rotates is used, and a plurality of warps are simultaneously warped while being replaced with different colors or different warps every predetermined warp length in the longitudinal direction of the warp.

  The difference between the second aspect of the present invention and the first aspect of the present invention lies in the location where the yarn guide is installed, that is, the yarn guide is provided on the rotary creel side (the first aspect of the present invention). 1) or provided on the warping drum side as in the prior art (second aspect of the present invention), when the yarn guide is provided on the rotary creel side (first aspect of the present invention). Since the yarn guide and the rotary creel rotate integrally with each other, there is no need for synchronous operation. On the other hand, when the yarn guide is provided on the warping drum side as in the past (second aspect of the present invention), it is necessary to synchronize the rotation of the yarn guide and the rotation of the rotary creel as in the conventional case. .

  Further, the sample warping method of the present invention is a sample warping method using the sample warping machine, wherein a plurality of warp yarns are replaced with different or different warps every predetermined warp length in the longitudinal direction of the warp. It is characterized by simultaneous warping.

  Furthermore, the rotary creel according to the present invention corresponds to each of the creel drum provided rotatably, the single or plural yarn joining mechanisms provided on the outer periphery of the creel drum, and the yarn joining mechanisms. A bobbin stand on which a plurality of bobbins can be detachably mounted is provided. If a plurality of yarn guides corresponding to the yarn splicing mechanism are fixed to one end of the creel drum in the longitudinal direction, the yarn guide can be integrated with the rotary creel. The trouble of synchronizing the rotation of the guide and the rotary creel can be eliminated.

  According to the present invention, simultaneously solving the disadvantage that it takes a long time for the warping work of the method using the fixed creel and the warping that only the limited pattern warping of the method using the rotary creel can be performed, In other words, the great effect of being able to provide a new sample warping machine, a sample warping method and a rotary creel that can warp in a very short time without causing limitations on the warping design. Play.

FIG. 7 is an explanatory side view showing a second embodiment of the sample warping machine of the present invention.

  First, the 1st aspect of the sample warper of this invention is demonstrated based on FIGS. In the figure, reference numeral 10 is a sample warping machine according to the first aspect of the present invention, and reference numeral 30 is an example of a rotary creel. The sample warper 10 is roughly divided into a warping drum 14 side (AA portion) and a rotary creel 30 side (BB portion) (see FIG. 1).

  A substantially cylindrical warping drum 14 (for example, a drum outer circumference length of 7 m) is provided with drum frames 15 and 16 and is pivotally supported on the base 12 by the main shaft pipe 11 and main shaft pipe metals 13a and 13b. A plurality of conveyor belts 17 and their drive rollers 17a that are movable in the longitudinal direction are provided on the outer peripheral portion of 14 (see FIG. 1). Further, on both sides of the warping drum 14, there are provided weaving bars 18a to 18f which are weaving means for forming predetermined weirs in the longitudinal direction, and are provided with guide means 21 for performing aligned winding warping (FIG. 2). Since this guide means 21 is described in detail in Patent Document 2, a re-explanation thereof is omitted.

  In the conventional sample warper 200, the front surface of the warping drum 214 is rotatable about the drum axis of the warping drum 214, and the warp Y is wound on the outer peripheral surface of the warping drum 214. In the sample warper 10 according to the first aspect of the present invention, the yarn guide is integrated with the rotary creel 30 as will be described later. Therefore, it is not necessary to provide a yarn guide on the front surface of the warping drum 14.

  The rotary creel 30 corresponds to each of the creel drum 34 that is rotatably provided, the plurality of yarn joining mechanisms 100a to 100h provided on the outer periphery of the creel drum 34, and the yarn joining mechanisms 100a to 100h. A bobbin stand 110 on which a plurality of bobbins B1 to B5 can be detachably attached, and one end in the longitudinal direction of the creel drum 34 (the end opposite to the warping drum 14) correspond to the yarn splicing mechanisms 100a to 100h. A plurality of yarn guides 6a to 6h are provided, and the yarn guides 6a to 6h are integrally provided with the rotary creel 30 (see FIGS. 1 and 3).

  The creel drum 34 is a cylindrical member having a diameter smaller than that of the warping drum 14, and is provided with drum frames 35, 36, and 37, and is rotatable to the base 42 by the drive shaft 31 and the drive shaft metals 33a and 33b. It is pivotally supported. A timing belt 45 is wound between the drive pulley 44 of the drive shaft 31 and the motor pulley 43 of the motor 48, and the drive shaft 31 is rotated by the drive of the motor 48. It can be turned (see FIG. 3).

  Further, on the outer peripheral portion of the creel drum 34, bases 40a to 40h are provided so as to be provided with yarn joining mechanisms 100a to 100h via the bases 40a to 40h, and one end of the creel drum 34 in the longitudinal direction (warping drum). A plurality of (for example, eight) yarn guides 6 a to 6 h for winding the warp Y on the outer peripheral surface of the warping drum 14 via the tip yarn guide member 2 are fixed to the end of the warp drum 14. A bobbin stand 110 to which a plurality of bobbins B1 to B5 are detachably mounted is provided at the other end in the longitudinal direction of the creel drum 34 (see FIGS. 3 and 4). 5). Therefore, as the creel drum 34 rotates, the yarn guides 6a to 6h, the yarn joining mechanisms 100a to 100h, the bobbin stand 110, and the like also rotate.

  Here, the yarn joining mechanism 100 used in the present invention will be described with reference to FIG. Reference numeral 100 denotes a yarn splicing mechanism. In addition, as the yarn joining mechanism 100, a yarn joining mechanism of a known winder (winding machine) can be used.

  The yarn joining mechanism 100 includes a bobbin stand 110 on which bobbins B1, B2, and B3 are detachably mounted, and a tension applying member that applies tension to the original yarns Y1, Y2, and Y3 drawn from the bobbins B1, B2, and B3, respectively. 111, a yarn selection device 120 that selects a desired yarn Ys from among the original yarns Y1, Y2, and Y3 tensioned by the tension applying member 111 and waits for the other yarn Yw, and the preceding and succeeding yarns The yarn joining device 112 performs yarn joining when the running yarns are different, and the yarn length measuring and storing device 130 that stores the warped yarn Y that has been spliced and measures the yarn length.

  Bobbins B1, B2, and B3 are bobbins around which original yarns Y1, Y2, and Y3 of different colors and types are wound, and the original yarns Y1, Y2, and Y3 pass through the tension applying member 111 and are selected by the yarn selecting device 120. And continuously supplied to the yarn length measuring storage device 130 while being spliced by the yarn joining device 112. In the illustrated example, three bobbins B1, B2, and B3 are shown mounted on the bobbin stand 110. However, the bobbins of the color types and thread types necessary for performing desired pattern warping are shown. It is attached to the bobbin stand 110, and there is no limit on the quantity.

  The yarn selection device 120 has a yarn guide 121 disposed for each of the bobbins B1, B2, and B3, and appropriately selects the yarns Y1, Y2, and Y3 and guides them to the yarn joining device 112 (selection). Position) 121A or warp Y is controlled to be movable to a yarn guide position (standby position) 121B for guiding the suction yarn 116 to the suction member 116.

  The yarn joining device 112 performs cutting and yarn joining of the original yarns Y1, Y2, and Y3. The yarns Y1, Y2, and Y3 selected by the yarn selecting device 120 are guided to the yarn joining device 112, and the yarn joining is performed. And the warp Y is formed. The yarn splicing device 112 may be a splicer device that splics yarn by an air vortex or a knotter device that performs yarn knotting.

  The yarns Y1 to Y3 sucked by the suction member 116 (on standby not guided to the yarn joining device 112) are held between the yarn holding roller 117 and the yarn holding plate 118. The yarn holding roller 117 is a roller member whose outer peripheral surface is covered with an elastic material such as urethane, and the yarn holding plate 118 is freely contactable with and separated from the yarn holding roller 117.

  The yarn length measurement storage device 130 rotates the rotation shaft 132 through a pulley and a drive belt by a motor 137, and a winding tube (not shown) branched from the rotation shaft 132 turns around the storage drum 133. The warp Y is stored in a spirally aligned state on the storage drum 133 while measuring and controlling the yarn length from the rotational speed of the motor 137 and the like. Then, the warp Y stored in the storage drum 133 of the yarn length measuring storage device 130 is supplied to the yarn guides 6a to 6h.

  The warp Y supplied to the yarn guides 6a to 6h is a warp Y because various colored yarns of the original yarns Y1, Y2, Y3 are spliced in a predetermined order and with a predetermined length to form a single warp Y. According to the length, it is possible to obtain warp Y having different colors such as red, yellow, blue and yellow. Further, not only the arrangement of the colored yarns but also an arrangement in which the yarn types and different count yarns are appropriately changed can be used.

  In this way, the warp Y is supplied to the yarn guides 6a to 6h while the yarn splicing mechanisms 100a to 100h are spliced by the yarn splicing mechanisms 100a to 100h so that the original yarns drawn from the bobbins B1 to B5 mounted on the bobbin stand 110 are in a desired arrangement. The warp layer Yd warped to a desired pattern is obtained by continuously winding the warp Y on the outer peripheral surface of the warp drum 14 via the tip yarn guide member 2 at the tip of the yarn guides 6a to 6h. Can be formed. However, by providing the rotary creel 30 with the yarn splicing mechanism 100 and the corresponding yarn guides 6a to 6h, a sample warper using a rotary creel that has conventionally been able to warp only a limited pattern. Even so, there is no time loss due to thread exchange, etc., and complex pattern warping can be performed freely without limitation, and a rotary creel that can warp complex patterns in a very short time. A sample-type warping machine 10 can be obtained. Further, since the yarn guides 6a to 6h are integrated with the rotary creel 30, there is no trouble of synchronizing the rotation of the yarn guide and the rotary creel as in the conventional sample warping machine 200 (see FIG. 8).

  Next, a second aspect of the sample warping machine of the present invention will be described with reference to FIG. In the figure, reference numeral 10A is a sample warping machine according to the second aspect of the present invention, and reference numeral 30A is another example of a rotary creel.

  In the sample warper 10 according to the first aspect of the present invention, the example in which the yarn guides 6a to 6h are provided integrally with the rotary creel 30 has been described. However, the yarn guide is not a rotary creel, but a conventional one. Similarly to the sample warping machine 200 (see FIG. 8), the warping drum can be provided. That is, on the front surface of the warping drum 14A, the yarn guide main shaft 53 and the yarn guide support portion 54 are made rotatable about the drum shaft of the warping drum 14A, and the warp Y is placed on the outer peripheral surface of the warping drum 14A. A plurality of (for example, eight) yarn guides 56a to 56h for winding via the yarn guide member 52 are provided. The yarn guides 56a to 56h are the same as those of the sample warper 10 according to the first aspect of the present invention except that the yarn guides 56a to 56h are not provided on the rotary creel 30A and are provided on the front surface of the warping drum 14A. The repeated description will be omitted.

  Even in this case, there is no time loss due to thread exchange, etc., and complex pattern warping can be performed freely without restriction, and a rotary creel system that can perform sample warping of complex patterns in an extremely short time. Sample warping machine 10A can be obtained. However, in the rotary creel 30A according to the second aspect of the present invention, the sample warping according to the first aspect of the present invention must be performed in synchronism with the rotation of the yarn guides 56a to 56h electrically or mechanically. Although it is somewhat complicated as compared with the machine 10, the synchronous operation technology of the yarn guides 56a to 56h and the rotary creel 30A is already established for many years (see Patent Document 3 and Patent Document 4). There is no particular difficulty. Rather, since the warping drum 14A has the same structure as the warping drum 214 (see FIG. 8) of the conventional sample warping machine 200, the conventional one can be used as it is, which is an advantageous aspect in terms of manufacturing cost. For the conventional sample warping machine 200 already installed in a factory or the like, it is only necessary to replace the rotary creel 230 with the rotary creel 30A in the present invention, so that the convenience is extremely high.

  In the above description, the case where the same number (eight in the illustrated example) of the yarn joining mechanisms 100a to 100h is provided corresponding to the yarn guides 6a to 6h has been described. However, the yarn joining mechanism is used for all the yarn guides 6a to 6h. If it is not necessary to perform the above, it is sufficient to provide the necessary number of yarn joining mechanisms 100a to 100h, for example, only one. In the first and second aspects, the yarn joining mechanisms 100a to 100h are not installed on the outer periphery of the creel drum 34, but are arranged on the base 42 of the rotary creels 30 and 30A. It is also possible to provide one or a plurality of 100h and stop the creel drum 34 when the yarn needs to be changed to change the yarn.
