The ball 41 in the groove c (at this time, the ball 46 is in the communication groove 4
6) into the cam grooves 11a and llb by pressing them with the side surfaces 72 and 73 of the grooves, respectively.

Each pair of solenoids 51 and 52 of the selection device 50 is a control device for the dropper device! (not shown), and two solenoids of any set are simultaneously energized by a command from the control device.

The above-mentioned cam plate 10, guide rail 20, slider 30, etc. are assembled so that the warp thread passing position (to be described later) is located on the upper part of the warp thread thread pulling mechanism 100 of the dropper device as shown in FIG. It is arranged in advance so as to be at the position of the head 101.

The operation of the selective transfer device 1 will be explained below.

The slider is stopped at the retracted position where 7133a and 33b engage with the pair of guide rollers 21. At this time, the balls 41, 46 are in positions A and H shown in FIG. 7 with respect to the cam arm 11. Under this condition, the control device energizes the coils of the solenoids (in this example the ones shown) 51, 52 of either set of the selection device f50. Then, the plungers 53 and 54 descend, causing the stopper bins 55 and 56 to protrude into the cam arms 11m and llb, respectively.
As shown in FIG. 7, the ball 46 at the upper end of the transfer arm 45 moves to the right in the cam holder 1a, and the ball 41 at the upper end of the take-out arm 40 moves to the right in the cam holder 1a, as shown in FIG.
Move to the right within tb. And in the middle of the move, ball 4
6 hits the stopper bin 55, its movement within the cam arm 1a is blocked, so the cam groove 11 passes through the communication arm 12m.
Move inside b. Similarly, when the ball 41 hits the stopper bin 56, it moves into the cam holder. When the slider reaches the forward position, the ball 46 is at position 1fH within the cam groove 11b, and the ball 41 is at the cam? Position F is reached within 1Illc.

When the ball 41 is in the cam groove 11b, the take-out arm 4
The lower end of the ball 41 is located between the healds 3 supported by two adjacent guide rods 2 as shown by the two-dot chain line in FIG.
As the top end of the 0 moves laterally in one direction (to the right in FIG. 4), the bottom end moves in the opposite direction until it is aligned with the row of healds as shown in solid lines in FIG. Therefore, when the slider reaches the forward position, the permanent magnet 42 attracts and holds the heald. On the other hand, when the ball 46 is in the cam arm 1111, the transfer arm 45
The lower end of the ball 46 is also located between the healds 3 supported by two adjacent guide rods 2, but when the ball 46 moves into the cam lllb, it moves laterally in the same way as the take-out arm 40 and moves to a position where it can engage with the heald. become. When the slider is in the forward position, the ball 46 is at position 11E within the cam 71111b.

When the slider moves backward (moves to the left in Fig. 3), the take-out arm 40 holds the heald while the ball 41 moves inside the cam holder and moves to the warp thread pull-in position (the ball 41 moves to the position ?&H as shown in Fig. 7). move to a certain point). When the slider starts to move, the guide roller 21 comes out of the slider 33 and the entire slider rises slightly, so that the heald itself is also moved in an elevated state. On the other hand, while the roller 46 moves within the cam groove 11b, the lower end of the transfer arm 45 first sends the heald with the warp drawn through from the warp thread pulling position to another position.

When the slider 30 has finished retracting and the balls 41 and 46 have reached positions WtB and A within the cams LIE and ILB, respectively, the switching plate 70 operates to move the upper end of each arm downward in FIG. Balls 41 and 46 are transferred to cam arms 11b and lla, respectively.

Thereafter, in the same manner, one of the healds supported by the plurality of guide rods is selected and moved to the warp thread pulling position, and the heald whose warp thread has been threaded is moved to the next position.

(g) Effects If the selective transfer device of the present invention is applied to a drawing device, it is possible not only to move the heald and dropper shade to the warp threading position, but also to automatically move the heald and dropper through which the warp has been passed to another position. , it is possible to improve work efficiency.
