This invention relates to a weft sub-length device for a loom, in which the measured weft is temporarily wound and stored, and the wound and stored culm yarn is pulled out at the time of weft insertion.

る。In general, shuttleless looms, especially fluid jet looms, are equipped with a weft length measuring device that measures the length of the weft for one weft insertion in advance and temporarily stores the measured weft. . This type of weft sub-lengthening device winds and measures the weft supplied from the weft supply section, stores the measured weft by wrapping it in -H, and when inserting the weft, pulls out the weft that has been wound and stored. A weft length measuring device has been proposed.

(-) controlled by at least one pair of weft locking bins.

回分の緯入れ長さだけ測長され、交互に緯入れされる。Now, when a woven fabric is woven by inserting one type of weft supplied from only one weft supply section, only one weft sub-length device is required; In the case where the weft yarn is supplied from the yarn supplying sections, as many weft sub-length devices as the number of yarn supplying sections are required. For example, when weft yarns are alternately supplied from the weft supply section in 2-), two weft length measuring devices are used, but in this case, the feeding speed of each weft yarn is The winding speed of the weft on the weft length measuring unit is the winding speed when only one weft sub-length device is used (hereinafter referred to as normal winding speed)
, and both wefts each have one half between two weft insertions.
The length of each weft insertion is measured, and the weft insertion is carried out alternately.

緯糸を供給することを２キシジグという）。This weft insertion method is used not only for supplying two colors of weft yarns, but also for supplying the same type of weft yarn from the weft supply section 2-] in order to make the woven fabric uniform with one type of weft yarn. (Feeding the same type of weft from multiple weft supply units is called a two-kiss jig).

ぁ−）だ。The weft insertion pattern described above can also be applied when there are three or more weft supply sections. In other words, when there are three weft supply sections, the winding speed of each weft is 9, which is the normal winding speed, and each of the three wefts has one winding speed during three weft insertions. The weft insertion length is measured and the weft insertion is performed sequentially. In addition, when there are four weft supply sections, the winding speed of each weft is the normal winding speed (= 1 of J speed, and each of the four wefts has one weft insertion between four weft insertions. Only the length is measured, and the weft is sequentially inserted.This is exactly the same when the weft supply section is 5-) or more. However, this weft insertion method is ineffective when the wefts supplied from each weft supply section are all different and are inserted sequentially, or when mixing is performed to make the woven fabric uniform. However, when inserting the same type of weft yarn a certain number of times in succession, it is necessary to prepare at least as many weft length measuring devices as the number of weft insertions just for this weft yarn.)Is it a defect? -).

が特開昭５６−５９７４０シＪ公報に開示されている。In order to eliminate this defect, in addition to the weft locking bin that is used in the conventional weft sub-length device, we have added an auxiliary locking pin that controls the transition of the measured weft in the weft insertion direction -3 from the weft outstanding bin. Japanese Patent Laid-Open No. 56-59740 discloses a weft sub-length device which is provided on the weft insertion side and is capable of inserting the same type of weft a certain number of times in succession.

なる。In this weft sub-length device, the weft yarn supplied from the two weft supply sections is continuously wound at a constant speed onto the winding surface of each weft sub-length device. For example, if one weft thread is inserted twice in succession, and then the other weft thread is inserted once, the winding speed of one weft thread will be the normal one, and the winding speed of the other weft thread will be the normal one. It becomes 1.

ばよい。In this weft insertion pattern, at the point when the weft on the - side is released from the auxiliary locking bin and inserted, the same weft is locked by the weft locking bin and the weft insertion length is Assuming that the other weft is being wound by one of the weft insertion lengths while being held by the weft handler 1 bin, then at the next weft insertion, the The weft yarn is wound by the weft insertion length while being held out by the weft locking bin, and the weft yarn that has been wound is released from the weft locking bin and inserted. At this time, the other weft has been wound by 1 of the weft insertion length, and at the next weft insertion, the same weft has been wound by the weft insertion length, and is released from the weft locking bin. The weft is inserted. Then, one weft yarn is pulled by -9 of the weft insertion length, and at the next weft insertion, the weft insertion length is held by the auxiliary locking bin and stored for winding.
The weft insertion length 1 is wound while being locked by the weft locking bin. Therefore, 1) It is only necessary to provide the auxiliary locking pin No. 11 in the weft sub-length device for measuring the length of one of the wefts (1-).

倍分巻（Ｊけられていなければならない。However, if the number of consecutive insertions of weft yarns supplied from one weft supply section increases, it becomes necessary to provide a plurality of auxiliary locking pins in a weft length measuring device that measures the length of the same weft yarn. For example, when one weft is inserted 4 times in a row, and then the other weft is inserted 3 times in a row (in this case, the winding speed of one weft is the same as the normal speed). A weft speed of 7゜ is a normal weft), and the weft on the - side is at least 23゜ of the weft insertion length at the time when the same weft starts to be inserted consecutively.

ない。This is because the amount of weft yarn that is kerbed by -1 is 13!- times the weft insertion length at the second weft insertion, 11 times the weft insertion length at the third weft insertion, and exactly the weft insertion length at the fourth weft insertion. Therefore, one of the weft yarns must be separately wound and stored by a pair of auxiliary locking pins for two weft insertions at the time when continuous weft insertion is started.

ることはできない。As the number of times that the weft yarns supplied from one weft supply section are continuously inserted increases, the number of auxiliary locking pins must be increased, which is not preferable because the structure of the weft sub-length device becomes complicated. . However, as long as the weft yarn is wound continuously, the above-mentioned defect cannot be eliminated.

The goal is to provide equipment.

The speed can be freely changed to constant speed, deceleration, speed increase, or stop based on the weft selection program, and the operation of the weft locking mechanism is controlled based on the weft selection program. There is no need to increase the number of weft locking bodies even if the number of consecutive weft insertions of the supplied weft yarn increases. Therefore, except in cases where the number of weft supply units increases or decreases and the weft length measuring device increases or decreases accordingly, it is possible to freely select and arrange wefts simply by changing the program without replacing mechanical parts. I can do it.
