Description

  The present invention relates to a bead weaving machine used for producing a bead fabric in which beads are woven.

  Conventionally, a bead weaving machine for producing a bead fabric in which beads are woven is known (see, for example, Patent Document 1). The bead weaving machine described in Patent Document 1 is a pair of left and right side plates opposed to each other at an interval in the left-right direction and a pair of thread winding rods (first 1 and a second thread fixing shaft) and a pair of spiral spring holding rods (first and second thread support shafts) rotatably connected to both side plates and spaced apart in the front-rear direction. One thread fixing shaft fixes one end of a plurality of warp threads, and the other thread fixing shaft fixes the other end of the plurality of warp threads. One yarn support shaft supports one end side intermediate portion of a plurality of warp yarns in parallel, and the other yarn support shaft supports the other end side intermediate portion of a plurality of warp yarns in parallel. . When the bead weaving machine having such a configuration is used, as shown in FIG. 1 of the same document, wefts inserted through the beads are woven into a plurality of warp yarns each extending in the front-rear direction and arranged in the left-right direction. Thus, a bead fabric can be produced.

  When producing a bead fabric having a long overall length of warp, first, the warp is wound around one thread fixing shaft. Next, a weft weaving operation is performed between the first and second yarn support shafts to form a fabric portion (see FIG. 2 of Patent Document 1). Next, while rotating one of the yarn fixing shafts to feed out the warp yarn, the other yarn fixing shaft is rotated to wind up the fabric portion. Then, weft weaving work is carried out on the newly drawn warp. By repeating such operations, a long bead fabric can be produced.

  As shown in FIG. 4 of Patent Document 1, both ends of the thread fixing shaft are provided with mandrels formed with screws. Screwed stoppers are engaged with these mandrels outside the left and right side plates. When the weaving operation is performed, when the stopper is tightened, the thread fixing shaft is sandwiched and fixed by the left and right stoppers via the left and right side plates. When the thread fixing shaft is rotated, the thread fixing shaft can be rotated by loosening one of the left and right stoppers.

  However, according to the above configuration, both the right and left stopcocks can rotate with respect to the mandrel when the stopcock is loosened. For this reason, in order to reliably rotate the thread fixing shaft, it is necessary to directly grip and rotate the thread fixing shaft itself. A warp yarn or a fabric portion is wound around the yarn fixing shaft. The work of rotating the yarn fixing shaft in such a state has been poor in workability.

  The connecting portion 4A connects the left front side plate 1C and the left rear side plate 1A, and the connecting portion 4B connects the right front side plate 1D and the right rear side plate 1B.

  Next, the structure of the thread fixing shaft 2A and the connection structure of the thread fixing shaft 2A to both rear side plates 1A and 1B will be described. Since the structure of the thread fixing shaft 2B and the connection structure of the thread fixing shaft 2B to the front side plates 1C and 1D are the same as those of the thread fixing shaft 2A, the thread fixing shaft 2A will be mainly described. Description of 2B will be omitted as appropriate.

  As shown in FIG. 5, cylindrical rotating shafts 211 and 212 are provided at both ends of the thread fixing shaft 2A. The rotating shafts 211 and 212 are inserted into holes 11 and 11 formed in both rear side plates 1A and 1B. Thereby, the thread fixing shaft 2A is rotatably supported by both the rear side plates 1A and 1B. A shaft end portion 213 is provided on the outer side in the axial direction of the rotation shaft 211 on the left rear side plate 1A side of the thread fixing shaft 2A.

  Next, a method of performing a bead weaving operation using the bead weaving machine A will be described with reference to FIGS.

  A case where a bead woven fabric having a relatively short overall warp length will be described. In this case, first, the thread hook 34 is attached to the attachment holes 341 of the thread support shafts 3B and 3A. Next, for example, one end of the yarn is fixed to the yarn hooking rod 34 of the yarn support shaft 3B, and the yarn is fitted into the groove portion 322 of the yarn support shafts 3B and 3A while extending forward and backward. Next, the yarn is wound around the yarn hooking rod 34 of the yarn support shaft 3A, and the yarn is extended in the front-rear direction and fitted in the groove portion 322 adjacent to the groove portion 322 in which the yarn is already fitted. This operation is repeated, and the other end of the warp T1 is fixed to the yarn hooking rod 34. In this way, as shown in FIG. 16, a plurality of warp threads T1 are supported side by side by the thread support shafts 3B and 3A. In the present embodiment, a plurality of thread hooks 34 are arranged along the axial direction (left and right direction) of the thread support shafts 3B and 3A, and the warp thread T1 supported by the thread support shafts 3B and 3A is the thread hook. It is divided into a plurality of areas corresponding to the bars 34.

  Next, as shown in FIG. 17, rod-like stoppers 39 are inserted into all the through holes 323 of the thread support portion 32.

  Next, the weft thread inserted from the needle tip into the bead is woven into the warp thread. Here, as shown in FIG. 18A, first, the weft T2 is lifted from the lower side so as to cross the warp T1, and each bead B is sandwiched between the adjacent warps T1. Next, as shown in FIG. 18B, the weft T2 is folded back with the warp T1 at one end in the left-right direction and passed through the hole of the bead B so as to pass above the warp T1. In this way, two wefts T2 are passed through each bead B, and the warp T1 is sandwiched between the two wefts T2 up and down. Next, the weft thread is inserted into the bead from the needle tip, and the weft thread is folded back again with the warp thread located at the other end in the left-right direction. The weft is then lifted from below so as to cross the warp and each bead is sandwiched between adjacent warps. By repeating such an operation a predetermined number of times, a bead fabric having a predetermined length in the direction (front-rear direction) in which the warp T1 extends is produced.

  Next, the stopper 39 is removed from the through-hole 323, the yarn support shafts 3B and 3A are slightly rotated, the warp yarn T1 is removed from the yarn hooking rod 34, and the bead fabric is removed from the bead weaving machine A. Then, by pulling out both ends of the warp T1, the portion that has been hung around the yarn hooking rod 34 passes through the beads and is in a completed state.

A pair of engaging portions 291 bulging in directions facing each other are provided at both end portions of the thread fixing tool 29. The thread fixing tool 29 is attached by elastically deforming the thread fixing tool 29 so that the dimension between the pair of engaging parts 291 is large, and engaging the engaging part 291 with the recess 215. When the thread fixing tool 29 is attached, the warp thread T1 is fixed by being sandwiched between the thread fixing shaft 2B and the thread fixing tool 29. Next, the yarn fixing shaft 2B is rotated to wind the warp yarn. Next, the warp yarn T1 is fitted in the groove portion 322 of the yarn support shafts 3B and 3A while extending backward. Next, the other end of the warp T1 is fixed to the yarn fixing shaft 2A. The warp yarn T1 is fixed to the yarn fixing shaft 2A in the same manner as the warp yarn T1 is fixed to the yarn fixing shaft 2B. In this way, as shown in FIG. 19, a plurality of warp threads T1 are supported side by side by the thread support shafts 3B, 3A.

  Next, as shown in FIG. 17, rod-like stoppers 29 are inserted into all the through holes 323 of the yarn support portion 32.

  Next, weaving work of the weft thread inserted into the beads is performed. The weaving work here is performed in the same manner as described above with reference to FIG. The weaving operation of the weft is advanced, and a fabric portion is formed between the yarn support shafts 3B and 3A. Next, the yarn fixing shaft 2B is rotated to feed the warp yarn, while the yarn fixing shaft 2A is rotated to wind the fabric portion around the yarn fixing shaft 2A. Then, weft weaving work is carried out on the newly drawn warp. By repeating such operations, a long bead fabric can be produced.
