Measure the length,
The weft thread is controlled by a weft thread gripper to control the start and end time of its flight, and the weft thread is inserted between the warp threads opened from a spray nozzle together with compressed water or compressed air, which is a transporting and pulling body for the weft thread. It is installed in a jet loom, specifically, for inserting one of two weft threads in a jet loom equipped with two each of the above-mentioned weft thread length measurer, weft thread gripper, and injection nozzle. a conduit switching device for guiding compressed water or compressed air to an injection nozzle associated with the weft yarn; a yarn guide control unit that controls a yarn guide of a weft length measurer associated with the weft yarn; The present invention relates to a device for selectively operating an opening/closing rod control section of a related weft thread gripper. By installing the weft insertion selection device of the present invention in the jet loom, it becomes possible to insert the two weft yarns in a free arrangement according to the desired intention, which makes it possible to insert the weft yarns in a freely arranged arrangement according to the desired intention. The jet loom, which has been put into practical use as a specialized loom, can freely weave textiles with design effects by freely arranging different colored threads for the two wefts, and texture effects by mixing and arranging threads with different properties. As a result, the field of production of low-cost, high-quality, high-value-added textiles has expanded dramatically.

があつた。(2) Conventional technology Conventionally, the weft selection method when inserting two weft threads individually in the jet loom has been carried out using a weft selection cam that rotates at a constant speed in synchronization with the movement of the loom. To weft the weft threads in an array according to the desired intention, either stop the loom operation and change the rotation speed of the weft selection cam (synchronization ratio with the loom rotation speed), or change the rotation speed of the weft selection cam. This was done by changing the displacement curve. For this reason, when inserting two weft threads while the loom is running, the selection is limited to a regular arrangement with extremely short cycles (alternating one thread or two threads alternately), and different types of weft threads are inserted. There was a drawback that it was not possible to weave a fabric with a design effect or a texture effect by freely arranging two weft threads according to the desired intention.

3 and 34 are pressed against the positioning plates 14 and 15 by springs 20 and 21 so as to be able to move up and down onto the upper surfaces of the transmission rods 16 and 17. The transmission lever 25, which has a pin 24 at the center of its length, which is the point of action of this link mechanism (b), has two transmission levers via elongated holes at both ends and pins 22 and 23 of the transmission rods 16 and 17. Rods 16 and 17 are linked. The movement of this link mechanism (b) is caused by the reciprocation of two series of transmission rods 16 and 17 operated by the movement of the reciprocating linear movement mechanism (a) via the selection pins 33 and 34 of the movement transmission selection mechanism (d). The linear movement is made into one series by the transmission lever 25, and the pin 24 of the transmission lever 25, which is the point of action, is positioned in the forward or backward position, and the pin 24 can be moved forward or backward every rotation of the loom. It is also characterized by being able to maintain the same forward or backward position continuously. Mechanically, the pin 24, which is the point of action, is positioned by the selection pins 33, 34, which are moved up and down by the selection pin contact ends 12, 13 of the transmission rods 6, 7, which alternately move forward or backward in a reciprocating linear motion every rotation of the loom. The movement of the transmission rods 16 and 17 is controlled depending on whether or not the head of the rod is pressed. In other words, at the timing when the transmission rods 16 and 17 should be positioned by the advancement of the transmission rods 6 and 7 of the reciprocating linear movement mechanism (a), both transmission rods 16 and 17 do not move forward together. When in contact with the positioning plates 14 and 15, the pin 2
4 is positioned in the retracted position, and the transmission rod 16,
The end of one of the selection pins 17 is located on the positioning plate 1.
4 or 15 and the other is moved forward by the transmission rod 6 or 7 via the selection pin 33 or 34, the pin 24 is positioned in the forward position.

A swing fulcrum end 31 is coupled to a switching shaft 32. The switching shaft 32 uses the transmission rods 27, 28 and the switching shaft 32 as fulcrums, which move back and forth in conjunction with the pin 24, which moves forward or backward in position by the movement of a parallelogram-like link mechanism (b). It swings and rotates by a required angle via a switching lever 29 that swings back and forth.

説明する。(5) Operation The overall motion of the device of the present invention consisting of the mechanisms (a), (b), (c), and (d) described above in section (4) is as follows. The basic movement of the selection pins 33 and 34, which move up and down in accordance with instructions from a weft selection control device (not shown), under the up and down conditions will be explained. Incidentally, when the selection pins 33 and 34 are moved up and down, the transmission rod 6 or 7 is retracted the most and a required distance is created between the selection pin contact end of the transmission rod 6 or 7 and the selection pin insertion hole of the transmission rod 16 or 17. It is done when it occurs. First, the related motions during forward movement of the transmission rods 6 and 7 of the reciprocating linear movement mechanism (a) will be described as first and second basic motions, and the related motions during backward movement will be described as third and fourth basic motions.

択・切り換えが行われる。 The first basic movement is that of the transmission rod 16 associated with one of the selection pins 33, 34.
This is the movement when the other selection pin 34 is rising while the selection pin end is in contact with the positioning plate 14. When the transmission rod 7, which is moved forward by the cam 3, pushes the head of the selection pin 34, the transmission rod 17 is moved forward. At the same time, the transmission lever 25 uses the pin 22 of the other stationary transmission rod 16 as a fulcrum, and the elongated hole end connected to the pin 23 of the transmission rod 17 moves forward, and the central pin 24 also moves forward. At this time, the switching lever 29 is connected to the pin 24 via the transmission rods 27 and 28,
At the same time as the switching shaft 32 moves forward using the switching shaft 32 as a fulcrum, the switching shaft 32 also rotates forward and is positioned at the forward rotation position. As a result, the injection nozzles 82, 83, weft thread length measuring devices 53, 54, and weft thread grippers 73, 74 of the main weft insertion mechanism of the jet loom shown in FIG. 2, which are related to the switching shaft 32, are selected and switched. .

ことなく後退回転位置を保つ。 In the second basic movement, as in the case of the first basic movement, one of the transmission rods 16 moves to the positioning plate 1.
This is a case where the other selection pin 34 is lowered while being in contact with the pin 4. Even if the transmission rod 7 starts to move forward, the selection pin 34 is lowered and is not pushed, so the transmission rod 17 does not move forward and the transmission lever 25 remains stationary.
Therefore, the member connected to the pin 24 of the transmission lever 25 is also stationary, and the switching shaft 32 maintains the backward rotational position without rotating.

決めされる。 The third basic movement is a case where the transmission rod 7, which has positioned the pin 24 of the transmission lever 25 and the switching shaft 32 linked thereto in forward rotation in the first basic movement, moves backward. In the other transmission rod 6 system that moves forward, if the selection pin 33 is lowered and the transmission rod 16 is in contact with the positioning plate 14 without being pushed by the transmission rod 6, the transmission lever 25 is stationary. It moves backward using the pin 22 of the other transmission rod 16 as a fulcrum.
At the same time, the switching shaft 32, which operates in conjunction with the pin 24 of the transmission lever 25, rotates backward and is positioned in the backward rotation.

ある。 The fourth basic movement is a case in which one of the transmission rods 7, which is positioned forward, moves backward, as in the case of the third basic movement. In the other transmission rod 6 system that moves forward, when the selection pin 33 is raised and the transmission rod 6 moves the transmission rod 16 forward via the selection pin 33, the transmission rod 7 system moves backward. Pin 2 of transmission rod 17
The elongated hole end of the transmission lever 25 linked to the transmission lever 3 moves backward, but at the same time the other transmission rod 6 moves forward.
The long hole end of the transmission lever 25 connected to the pin 22 of the transmission rod 16 moves forward. Here, as mentioned above, since the transmission rods 6 and 7 are linked with the cams 2 and 3 having the same displacement curve in completely opposite directions with a phase shift of 180 degrees, the transmission rod 7 moving backward
and the pin 23 of the transmission rod 17 linked thereto.
The timing and amount of movement of the two are exactly the same as those of the other forward moving transmission rod 6 and the transmission rod 16 and pin 22 linked thereto. Therefore, the transmission lever 25 is
Since the pin 24 is stopped at the forward position without moving backward, the switching shaft 32 linked to the pin 24 also moves forward without rotating backward. It remains in the rotated position. The fourth basic movement has been explained as the movement when the transmission rod 7 moves backward, but at the same time the other transmission rod 6 moves forward, so the basic movement is the movement when the transmission rods 6 and 7 move forward. This also applies to exercise.

回転位置決めを行うものである。 In this way, the overall movement of the device of the present invention is achieved by the transmission rods 6 and 7, which alternately move in a reciprocating straight line in conjunction with the cams 2 and 3, which rotate in synchronization with the movement of the loom, and by the instructions of the weft thread selection control device (not shown). Accordingly, one of the four basic movements described above is selected for each revolution of the loom in relation to the selection pins 33 and 34 which move up and down, and the rotational position of the switching shaft 32 of the final operating member is determined. be.

作用を行うものとする。 In this description, the forward rotational position of the switching shaft 32 is assumed to be the A-thread switching position, and the backward rotational position is assumed to be the B-thread switching position. In addition, two cams 2 and 3
The two movement systems linked to each other operate alternately for each rotation of the loom (one weft turn), so the movement system linked to cam 2 operates at odd-numbered weft turns and cam 3.
It is assumed that the operation of the motor system linked to the operation selects even-numbered weft insertion.

がＢ糸の場合は前述の第１の基本運動に相当し、
Ａ糸の場合は第４の基本運動に相当する。 First, if the first (odd numbered) weft insertion instruction by the weft selection control device (not shown) is A yarn, the selection pin 33 of the movement system of the cam 2 that performs selection control of the odd numbered weft insertion is raised, and the cam 2 The transmission rod 6, which moves forward in conjunction, pushes the head of the selection pin 33 and moves the transmission rod 16 forward, so that the switching shaft 32 is switched to the forward rotation position (for A yarn). This movement corresponds to the above-mentioned first basic movement when the previous (even number) weft insertion is B yarn.
In the case of A yarn, this corresponds to the fourth basic motion.

れは第３の基本運動に相当する。 If the second (even number) weft insertion instruction is B thread,
Since the selection pin 34 of the movement system of the cam 3, which controls the selection of even-numbered weft insertion, is lowered, the transmission rod 7, which moves forward in conjunction with the cam 3, does not push the selection pin 34, and the transmission rod 17 performs positioning. Board 1
5 and is stationary, the switching shaft 32 is moved by the action of the movement system of the other cam 2 that moves backward.
is switched to the backward rotation position (for B yarn). This corresponds to the third basic movement.

３２は後退回転位置（Ｂ糸用）に静止している。
これは第２の基本運動に相当する。 If the third weft insertion is the same B thread as the second thread, the selection pin 33 of the movement system of the cam 2 is lowered, so the forward moving transmission rod 6 does not move the transmission rod 16 forward, but instead moves backward. Since the transmission rod 17 of the movement system of the other moving cam 3 is also in contact with the positioning plate 15 and stationary, the switching shaft 32 is stationary at the backward rotation position (for B yarn).
This corresponds to the second basic movement.

当する。 When the fourth weft insertion instruction is for yarn A, the selection pin 34 of the movement system of the cam 3 is raised, so the transmission rod 7 moving forward moves the transmission rod 17 forward, but the movement of the other cam 2 moving backward Since the transmission rod 16 of the system is stationary and in contact with the positioning plate 14, the switching shaft 32 is switched to the forward rotation position (for A yarn). This corresponds to the first basic movement.

する。 If the fifth weft insertion instruction is for the same A yarn as the fourth yarn, the selection pin 33 of the movement system of the cam 2 is raised, so that the forward moving transmission rod 6 is the same as the transmission rod 1.
The transmission rod 7 of the movement system of the other cam 3, which moves backward, moves the transmission rod 17 backward through the selection pin 34 in contact with it, so that the switching shaft 32 is in the forward rotation position ( For A thread) It is stationary. This corresponds to the fourth basic movement.
