The lower separating rotary shaft 36a is interlockingly connected to the separating rotary member 14 via a spiral gear 39 and an interlocking gear mechanism 40. In this way, the separating rotary member 14 is attached to the separating rotary shaft 36 via the spiral gear 39.
By interlocking with a, the axis of the separating rotary member 14 is inclined at an appropriate angle with respect to the direction perpendicular to the axis of the separating rotary shaft 36a. The upper separating rotary shaft 36b is interlockingly connected to the pressing rotary member 15 via a bevel gear 41 and a timing belt interlocking mechanism 42.
The axis of 5 is perpendicular to the axis of the separating rotary shaft 36b. An interlocking mechanism 48 for interlocking the separating rotary member 14 and the pressing rotary member 15 is configured by these 36a, 36b to 42.

A hammer plate up / down cam 44 is provided.

As shown in FIGS. 8 and 9, the separating rotary member 14 is formed by projecting a separating plate 45 on the outer periphery of the main body boss 14a, and outside the separating plate 45 as the main body boss 14a rotates. The inclined side edge portion 46 formed on the edge is configured to move in the longitudinal direction of the warp while being pressed against the end portion of the untwisted warp yarn group 5a from below. Further, the axis of the separating rotary member 14 is inclined at an appropriate angle with respect to the direction perpendicular to the axis of the separating rotary shaft 36a so that the lower side of the inclined side edge portion 46 is located forward in the moving direction. And
This causes the warp to be scraped up in the separating direction as the inclined side edge portion 46 moves due to the rotation of the separating rotary member 14 about the axis. Further, the thickness of the inclined side edge portion 46 is gradually reduced toward the lower side, and the warp yarns are separated by a step. The farthest warp yarns 7 that have been moved with the space widened toward the higher side of the inclined side edge portion 46 of the separation plate 45 are hooked on the separation needle 17 and are indicated by arrows, as shown by the phantom line in FIG. 8. The yarn is moved in the direction to be completely separated, and is further moved by the yarn carrying lever 34 (see FIG. 5) toward the yarn group 5b for the finished warp yarns.

As shown in FIG. 3, the pressing rotary member 15 is provided with a pressing plate 47 protruding in the diametrical direction for pressing the end of the untwisted warp yarn group 5a from above. As shown in FIG. 3 and FIG. 9, the separating rotary member 14 and the pressing rotary member 15 are interlocked with each other so that the pressing plate 47 is in pressure contact with the warp group 5a at the rear position in the moving direction of the separating plate 45.

In the above structure, when the driving means 33 rotates the separating rotary shafts 36a and 36b in the interlocking mechanism 48 of FIG. 7 in conjunction with each other through the interlocking means (not shown) as appropriate, FIG. As shown in 11, while the separating rotary member 14 and the pressing rotary member 15 rotate,
The first and second hammer plates 18 and 19 and the separating needle 17 perform a predetermined operation to separate the warp 7 at the end of the unseparated warp group 5a.

That is, in FIGS. 10 and 11, the separating rotary member 14 is directed from the state of (a) to the state of (b) as indicated by an arrow.
When the rotation member 15 for pressing and rotating rotates, the separation plate 45
The slanted side edge portion 46 of the warp yarn is pressed against the end portion of the warp yarn group 5a and moves in the longitudinal direction of the warp yarn, and accordingly, the warp yarn 7 moves in a direction in which the tension becomes higher according to the magnitude of the tension. The space between can be widened. Next, as shown in (b) to (c), the pressing plate 47 is pressed against the warp group at the rear position in the moving direction with respect to the separating plate 45, and
The first and second hammer plates 18, 19 descend and hold the warp 7 so as to be slightly pushed between the fixed guides 16a, 16b, and at the last stage, as shown in (c), the first hammer plate 18 By oscillating in the direction opposite to the moving direction of the separating plate 45, the tension is more effectively applied to the warp yarns 7, the separating performance is improved, and the warp yarns 7 can be reliably separated even at high speed.

Further, as described above, since the shaft center of the separating rotary member 14 is inclined at an appropriate angle, it acts so as to scrape up the warp 7 in the separating direction as the separating plate 45 moves. Further, the thickness of the inclined side edge portion 46 is gradually reduced toward the lower side, and the warp 7
Since the warp yarns are separated, the warp yarns 7 can be separated more reliably and with high reliability.

The farthest warp yarns 7 separated from the unseparated warp yarn groups 5a are hooked on the separating needle 17 and the warp yarns 7 shown in FIG.
Moved in the direction indicated by the arrow in (c) and completely separated,
Further, the yarn transfer lever 34 shown in FIG. 5 is moved toward the warp-finished warp group 5b. In this way, when the warp yarns 7 are separated and moved to the set warp yarn groups 5b, the shuttle position switching rotary shaft 2
The push rod 20 in each shuttle holder 13 operates by the rotation of 5a and 25b, and the shuttle 11 held in the upper shuttle holder 13 is held in the lower shuttle holder 13 and in the lower shuttle holder 13. The position of the shuttle 11 that has been operated is switched to the shuttle holding portion 13 on the upper side.

At that time, as described above, the warp yarns 7 are formed by the warp yarn groups 5a.
When it moves from 5 to 5b, it is detected by the separated yarn detector 35 and the number of passing warp yarns 7 is counted by the counter 51. Then, in the presetter 52, the number-of-passages pattern corresponding to the traverse tissue set in advance and the counted number of passages are compared and calculated by the arithmetic circuit 53, and control is performed when it is necessary to switch the vertical position of the shuttle 11. A signal is output, and the control signal amplified by the amplifier 54 is input to the electrical control unlocking mechanism 31.
1 operates to switch the position of the shuttle 11.

By repeating the above operation, the twilling unit 8 is sequentially moved so as to traverse the warp group 5 while passing the twill string 10 through the warp yarns 7 alternately one after another, and the arbitrary value set by the presetter 52 is set. The twilling work of the twill design is performed on the entire warp group 5.

According to the automatic traversing machine 1 of the above-mentioned embodiment, the traversing speed, which has been about 200 filaments / minute in the past, is about 400 filaments / minute.
It is possible to carry out the twilling at a high speed of about a minute, and it is possible to carry out the twilling operation of an arbitrary twill structure by a simple setting.

[0031]

According to the automatic twilling machine of the present invention, the warp yarns passing between the tips of the twill cords can be set by simply setting the warp passing number pattern corresponding to the twill structure by the setting means as described above. Since the switching operation of the tip position of the twill cord is controlled according to the number of warp yarns that are detected and set by the setting means, any twilling work of the twill structure can be performed only by a simple setting operation.

Further, by disposing an electric control disengagement mechanism controllable by the control means in the drive path of the traverse end position switching means, it is possible to carry out the traverse work of any twill structure with a mechanically simple structure. You can

Further, the control means may be constructed so that the number of warp passing threads is counted by a counter, and the calculating means compares and calculates the number of passing threads corresponding to the twill structure set by the setting means to output a control signal. It is possible to easily select an arbitrary twill structure from a large number of twill structures and perform the twilling operation.
