本発明は、杼口に侵入できる往復投糸器を備えたシャト
ルレス織機に横糸を挿入す、一位置に関する。DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION The present invention relates to a position for inserting weft threads into a shuttleless loom equipped with a reciprocating thread thrower which can penetrate into the shed.

外側に配置されるボビンから引き出される。[Prior Art 4] The weft thread insertion device is formed with a thread thrower that pushes the thread into the shed from each side of the loom and then returns. , the end of the thread thrower entering the shed supports a head which pinches and guides the weft thread inserted into the shed during the insertion period. The weft thread is drawn from a bobbin located outside the shed.

掛けなければならない。Various weaving machines already exist in which the weft thread is drawn from the bobbin to a picking device, for example a picking device consisting of a mechanism with a spring-loaded lever, usually called an entry head, fixed to the end of a thread thrower. The weft yarn is picked up at the inlet head and drawn out a distance within the shed to an area where it is sent to another caster head, usually called the outlet head. This outlet head also consists of a mechanism with a spring-loaded lever. After the weft yarn has been transferred from the inlet head to the outlet head in the shed, it is drawn through the shed platform to the other end of the fabric by a thread caster supporting the outlet head. The transmission of the weft thread from the inlet head to the outlet head is effected automatically and effectively by the particular configuration of the two heads. The weft thread is picked at the entry head within the self-locking clamp and retained at the exit head within the self-locking hook. When the entry head delivers the weft thread to the exit head, a self-locking hook must grasp the weft thread and hook it sufficiently to remove it from the entry head.

とが必要であるが、横糸を同時に何本も挿入することが
不可能である。``Problems to be solved by the invention'' This principle has various drawbacks. The weft threads tend to come off at any moment during insertion and are insufficiently hooked by one or the other of the two heads, causing defects in the fabric. Of course, some fabrics require the insertion of several weft threads, but it is not possible to insert several weft threads at the same time.
摘み領域が常に閉塞しているので、横糸の屑が摘み領域
に詰まって累積されて、ヘッドがその機能を正常に形成
することを防止している。これは、横糸が滑って移動し
、従ってヘッドから外れることとなる。Since the picking area is constantly occluded, weft thread debris gets stuck in the picking area and accumulates, preventing the head from forming its function properly. This results in the weft threads slipping and therefore coming off the head.

'8,284, for example, it is difficult to pick up large diameter or thin weft threads with the same clamping device, making it difficult to combine various weft threads. To overcome these drawbacks, the above-mentioned patent proposes a solution in which a positive clamping of the weft thread is ensured during the transition from the inlet head to the outlet head in the shed during insertion, when the weft thread is pinched at the inlet head. The measures are listed. The solution proposed in this patent to achieve such a result is that the head of the thread thrower is equipped with a picking lever or branch whose opening and closing for picking or releasing the weft thread is actively controlled from the outside. It depends on being there. The solution described in this patent concerns the picking of the weft thread by the inlet head on the feed side and the release of the weft thread by the outlet head when the weft thread has been inserted over the entire width of the fabric, and the inlet head in the middle of the shed on the other hand. Regarding the transition from the exit head to the exit head, which is satisfied, the main problem is that the means for controlling the opening and closing of the knob lever of the exit head must pass through the warp group below the warp group forming the shed. There is. Such contact between the control means and the weft threads causes wear of the weft threads, risking defects in the fabric and even breaking of the weft threads. Furthermore, the friction occurring between the control means and the weft threads causes the formation of fiber debris, which falls and adheres to the mechanisms located at the bottom of the shed, causing these mechanisms to become dirty and deteriorate rapidly. It happens.

From there, the weft thread 54 is passed to the inlet head 6 by the feeding mechanism 13. As a result, the shedding mechanism 17, whose structure and operation will be described below, controls the opening of the branch of the inlet head so that the branch pinches the weft thread. After a short period of time, the mechanism 17 controls the branch to close, so that the core-spun yarn is pinched off at the entry head 6. The thread thrower 5 advances in the shed, and at the same time the thread thrower 7 advances from the opposite side and meets the thread thrower 5. Once the weft thread has advanced through the entrance head 6 to approximately half the width of the loom, a mechanism for opening and closing the heads 6 and 8 according to the invention built into the head is shown in one embodiment in Figure 4, a=c. The loom is operated by control means located on each side of the loom. In this case, the relay means for controlling the internal mechanism acting on the rotating branch of each head consists of rods 18 and 19, one end of which is connected to a sliding member within each head, and the other end of these rods 18 and I9. are connected to catches 20 and 21 which come into contact with stop members 22 and 23 located on each side of the loom during movement of the thread thrower. The transmission of the control for opening the branch is therefore carried out within the shed without contacting the warp threads forming the shed. When the weft is transferred from the inlet head 6 to the outlet head 8, the thread thrower moves back;
During this retreat, the weft to the exit 1) 8 is completely pulled out in the shed. When the exit head 8 arrives outside the shed, an additional mechanism 16 opens the branch of the exit head 8 to release the weft thread.

面間で得られている。Referring to FIG. 2, the caster 5 includes an inlet head 6 located within a capture mechanism that allows opening of the branch 24. , this catching mechanism consists of a catch 20 connected to a rod 18 that slides in a guide 2G attached to each body of the thread caster 5. On the head side, a relay rod I8 is fixed to a sliding member 28 that performs various functions. In addition to guiding the rod 18, this sliding member also pivotally supports a roller 30 that comes into contact with an inclined surface 32 formed on the branch body. Further, the sliding member is biased by a spring 34. When the gage 20 is pulled to the right with respect to the thread caster 5, the roller 30 pushes against the inclined surface 32 of the branch 24, causing the head 6 to rotate about the pin 36 and thus causing the opening of the picking area 40. . When the push on the catch 20 is released, the roller 30 is returned to the initial position by the spring 34. As a result, the branch body 24 is connected to the spring 3
8 and is biased back to the initial position, so that the pinch area 40
to ensure occlusion. FIG. 3 details the particular structure of the pick area 40, which is similar in structure to that of the outlet head. This inlet head 6 has an elastic (elastomer) band 38 placed on the surface of the branch body 24 and sandwiched between the branch body and a steel plate 39 . By means of this elastic band 38 a completely flat grip is obtained between the surface of the head and the surface of the branch 24.
