The wheel 5 drives a band loop connected to the rapier head 3, the servo motor 6 for rotating and driving the wheel 5, and the servo motor 6 is program-controlled. And a control device 7. Especially the servo motor 6
Is a numerically controlled servomotor that drives and controls using a numerical position detecting means such as an encoder, so that the control device 7 can easily obtain the position information of the rapier head 3. 8, the weft i.e. re weaving for Pattern yarn 1 or ground yarn woven implanted before reed of the loom, 9 detects the mark 2 1 arranged and re woven for pattern yarn 1 on the downstream side of the weft before weaving optical sensor, 10 is an optical sensor for detecting the mark 2 2 upstream pattern for arranged and re-woven into the side yarn 1 of the weft before weaving.

However, even if the optical sensor 9 and the optical sensor 10 erroneously detect the color of the pattern of the woven fabric in the rewoven pattern yarn 1 as the marks 2 1 and 2 2 , the control device 7 does not malfunction. Disables the information from the optical sensor when the optical sensor detects the pattern portion of the weaving width of the rewoven pattern yarn 1 from the position information of the rapier head 3 obtained for drive control by itself, The information from the optical sensor is valid only when detection is performed at the ear, that is, at the end of the rewoven pattern yarn 1. That is, the grasping operation of the weft grasping device which is disposed on the upstream side of the later-described weft and grips the weft is also detected by the optical sensor 10 at the ear of the rewoven pattern yarn 1 by obtaining the position information from the controller 7. Only when this is done, the information from the optical sensor 10 is validated.

し前進・後退するものである。In a normal loom, a plurality of wefts are waiting in line at the right or left front of the weave, and one hook is used at the timing when a conveying member for grasping and conveying the weft comes out. Is stretched on the movement extension line of the conveying member. In such a weft selection method,
Since the weft is bent into an acute locus by a hook or the like and an unreasonable force is applied, the rewoven pattern yarn 1 in which only the four core yarns are woven and twisted may cause the fluff to fall off. There was. Therefore, the above-described weft selection device of the present invention
The pattern yarn holding standby member 15 and the ground yarn holding standby member 16 are positioned on the extension of the rapier head 3 and are selectively advanced and retracted, so that the rewoven pattern yarn 1 is slightly inclined by the weft tension member 14. The trajectory can hardly bend except that the trajectory is extended. This makes it possible to weave a high-quality woven fabric without fluff falling off. In order to achieve such a configuration, the weft grasping device 12 and the weft cutting member 13 of the present invention move forward and backward with respect to the movement extension line of the rapier head 3.

4 lifts upward to make the re-woven pattern yarn 1 easy to be fed out, and the pattern-yarn holding standby member 15 releases the re-woven pattern yarn 1, and at the same time, the rapier driving device 4 releases the re-woven pattern yarn 1. The gripped rapier head 3 is transported to the left in the width direction of the woven fabric. Then, the weft grasping device 12 and the weft cutting member 13 move forward and are positioned so as to sandwich the rewoven pattern yarn 1 vertically. In this manner, the rewoven pattern yarn 1 pulled by the rapier head 3
Is carried into the opening of the warp.

柄糸１を切断する。[0017] FIG. 6 shows the moment when the light sensor 10 disposed upstream of the weft detects the mark 2 2 Re woven for Pattern yarn 1 before weaving. The weft grasping device 12 grasps the re-woven pattern yarn 1 based on the signal from the optical sensor 10, but due to a time delay until the re-woven pattern yarn 1 is grasped or the re-woven pattern yarn 1 elongation, etc. mark 2 2 woven for pattern yarn 1 stops gone too far to the position of the optical sensor 10. For this reason, the weft grasping device 12 grasping the rewoven pattern yarn 1 (or both the weft grasping device 12 and the weft cutting member 13 are also possible).
As shown in FIG. 7, the drive device (not shown) slowly moves to the upstream in the running direction of the rewoven pattern yarn 1. And
When the light sensor 10 is stopped precisely at a position detecting the marks 2 2 Re woven for pattern yarn 1, the weft cutting member 13 Pattern for woven re with pattern yarn gripping standby member 15 grips the use pattern thread 1 Woven re Cut thread 1.

Then, in some marks 2 2 Re woven for Pattern yarn 1 timing and or simultaneous was positioned precisely delayed timing position of the optical sensor 10 described above, the mark light sensor 9 is re-woven for Pattern thread 1 2 1 And stop exactly at that position. During the above-described series of weft carry-in operations, the loom main body, that is, the beat-up motion is stopped. Then, the re-woven pattern yarn 1 whose both ends are gripped and accurately positioned and fixed by the rapier head 3 and the weft grasping device 12 is driven by a loom in a state where the pattern is accurately aligned.

ある。As described above in detail, according to the rewoven pattern yarn positioning apparatus of the present invention, the end of the weaving width of the chenille rewoven pattern yarn has a color different from the ground color. Two marks are formed at intervals, and optical sensors for detecting the marks are provided at positions corresponding to both ends of the cloth fell, respectively, and between the two marks on the upstream side of the weft in the cloth fell. When the weft conveying device grips the end of the rewoven pattern yarn cut in the above and carries it to the opening of the warp, the optical sensor disposed on the upstream side of the weft before weaving is moved to the upstream side of the rewoven pattern yarn. The weft grasping device disposed at a position corresponding to the optical sensor on the upstream side detecting the mark, grasps the rewoven pattern yarn, stops the rewoven pattern yarn at a predetermined position, and The optical sensor disposed on the downstream side of the By detecting the mark on the flow side and the weft conveying device stopping the re-woven pattern yarn at a predetermined position, the marks at both ends of the re-woven pattern yarn having the weaving width using two optical sensors respectively. By adjusting to the exact position,
A high quality woven fabric that has been accurately patterned can be automatically woven by a loom without manual work.

とが可能となる。Also, a weft selection device comprising a pattern yarn gripping standby member for gripping and holding the end of the rewoven pattern yarn and a ground yarn gripping standby member for holding the end of the ground yarn and waiting for it is provided. Along with being arranged on the upstream side of the weft in the device, when the weft conveying device grips the rewoven pattern yarn or ground yarn, the pattern yarn grip standby member or the ground yarn grip standby member is an extension of the rewoven pattern yarn. When moving selectively, the rewoven pattern yarn is conveyed along a path that hardly bends without applying excessive force, so weaving a high-quality woven cloth without fluff falling off can be performed. It becomes possible.

を確実に防止することができる。The position of the mark is calculated from the position of the weft conveying device detected by the position detecting means of the numerical control servomotor. When the position of the mark is within the range of the pattern portion of the weaving width, the output of the optical sensor is output. By disposing a control device that invalidates the mark and activates the output of the optical sensor when the position of the mark is out of the range of the pattern portion of the weaving width, the optical sensor can change the color of the woven fabric pattern in the rewoven pattern yarn. Erroneously detected as a mark can be reliably prevented from malfunctioning.

のである。Further, the weft grasping device gripping the rewoven pattern yarn reciprocates along the running direction of the rewoven pattern yarn in order to align the mark of the rewoven pattern yarn with a predetermined position. Even if the mark of the rewoven pattern yarn held by the weft grasping device by the detection is overrun, the rewoven pattern yarn can be returned so that the mark comes to an accurate position. Thereby, the pattern matching of the re-woven pattern yarn can be performed more accurately than ever before.
