Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a device for adapting the feed of the special striped yarn to the stopping position of the batten.

Special threads such as foil threads are used as weft threads in the form of separated threads that are cut to the required length and formed into separate threads, and their weaving (weft insertion) temporarily stops the batting movement. In this state, one piece of foil yarn is sent by a yarn feeder to a weft guidance device installed in the batten (stripe), and by moving the spatula in a favorable running direction, it is pulled into the sugiguchi, and the battan movement is carried out. It will be driven in by the restart. Conventionally, in this type of striping work, a large number of foil threads are lined up in parallel on a thread holder installed above the side of the loom, facing in the left-right direction of the loom, with one end protruding from the thread holder towards the loom. Each foil thread is sequentially fed to a fixed position, that is, a picking position, according to its order by a feeding device such as a roller feeding device, while a thread feeding device is used between the loom and thread holding. The thread feeder is equipped with a rotatable shaft equipped with an arm with a thread picker attached to the tip, which is arranged in the front-rear direction of the loom, and the thread feeder has a rotatable shaft equipped with an arm with a thread picker attached to the tip. Rotate the arm from a standing position to a right angle to the loom side by repeatedly rotating the arm,
The thread feeding mechanism is configured to return the thread from the betting state to the upright state.

In this way, when the arm of the thread feeder is in an upright position, the thread pincher picks up the protruding part of the foil thread at the picking position on the thread holding table, and then moves the thread to the right (or left) toward the reed circumference of the shaft. ) is rotated to move the arm toward the loom, the foil thread on the thread holder is pulled out from the thread holder, and the pulled foil thread is rotated around the shaft and the arm is rotated at right angles. When the foil thread is folded down, the tip (lower end) of the foil thread becomes vertical and is fed into the hole of the spatula for guiding the striped thread. When feeding foil yarn like this,
The foil thread picked up by the thread picker is always fed into a fixed position with its tip oriented vertically, but the stop position of the weft yielding spatula on the receiving side is not necessarily fixed. Because it is installed on the batten, the positions of the thread pincher and striped thread guide may not match.
As a result, there was a problem in that the foil yarn could not be accurately fed from the yarn holder to the striped yarn guiding spatula.

This invention has been developed in view of the above points, so that the foil yarn can be reliably fed from the yarn holding table to the striped yarn guiding spatula no matter where the batten stops when the loom temporarily stops for inserting the foil yarn weft. The purpose is to

In this invention, after a predetermined foil yarn located at a picking position on a thread holding table is picked up by a thread pincher, during the rotational transfer of a weft thread guiding spatula, the thread pincher is moved by following the stop position of a batten. The front and rear positions are automatically adjusted to ensure that the front and back positions of the thread picker and the weft guiding spatula are constant when transferring the foil yarn, thereby ensuring that the foil yarn can be transferred reliably. It is something to do.

Next, the present invention will be explained based on embodiments shown in the drawings.

As shown in FIG. 1, a rod 4 is pivotally connected in the front-rear direction of the loom to a portion of the batten 1 on the front side of the loom, such as a thread 2, via a mounting bracket 3.
A cam 5 is formed on the top of the free end side of the cam 5, which has a mirror slope facing diagonally downward in the front direction.

This cam 5 is in contact with a roller 6 provided on an arm 7 fixed to one end of a freely rotatable shaft 8 disposed in the left-right direction of the loom, and the other end of the shaft 8 is provided with a plate-shaped portion having a wide front portion. The position adjuster 9 is fixed. The rod 4 follows the movement of the batten 1 and moves repeatedly in the front and back direction, and stops according to the stop position of the batten 1. When the batten 1 stops at the position closest to the weaving side, the roller 6 moves to the side of the cam 5. On the other hand, when the batten is stopped at the most forward position, the roller 6 comes into contact with the lowest position of the curved surface of the cam 5.
The position adjuster 9 moves in the front-rear direction in response to changes in the vertical position of the roller 6 due to contact with the cam 5, and when the roller 6 is at its lowest position, it is in the state where it is most pushed towards the tip of the machine. 10 indicates a cam support.

In this way, the position adjuster 9 is designed to change its longitudinal direction depending on the stop position of the batten 1, and other mechanisms for moving the position adjuster 9 are shown in FIGS. 2 and 3. This is shown below. The one shown in FIG. 2 is a cam in which a low foot 6 is provided on the free end side of a rod 4, and this roller 6 is attached to a shaft 8 with a sloped surface facing diagonally upward at the lower end of an arm 7 that is fixed to a shaft 8. The shaft 8 shown in FIG. 3 has a relatively long arm 7 having a roller 6 at its tip and a position adjuster 9 arranged at right angles to each other.

Reference numeral 11 indicates a yarn feeder installed on the side of the loom.

The single thread feeder 11 has a rotating shaft 22 supported by an underframe 23 placed behind the position adjuster 9 so as to be movable in the front and back direction parallel to the rod 4. A rotating arm 24 having a thread pincher 15 at its tip is fixed to the part that protrudes from the shaft, and a part of the rotating shaft 22 that projects forward from the underframe 23 is formed at a required angle with the rotating arm 24. axis 25
is fixed thereto, and a longitudinal controller 12 is provided with a sliding bale roller 26 attached to its tip. Reference numeral 21 denotes a coil-shaped push spring that is iron-mounted on the rotating shaft 22, and is interposed between the front side shaft bearing part of the underframe 23 and the collar 20 that is fixed at an appropriate position on the rotating shaft 22, and is inserted to push the rotating shaft 22 in the rearward direction. It has the effect of pushing it.

Reference numeral 18 denotes a drive rod that is pivotally connected to the rolling arm 24 of the thread feeder 11, and is reciprocated in the left-right direction by an appropriate reciprocating mechanism, and this reciprocating movement causes the rotating arm 24 to change from an upright state to a folded state. , and repeatedly rotates from the troubled state to the upright state.

13 indicates a knob position stop that can be formed protrudingly on the underframe 23;
The knob position stopper 13 is disposed side by side with the position adjuster 9 in the left-right direction and at a position that is biased toward the loom side than the position adjuster 9.

When the rotating arm 24 of the yarn feeder 11 is in the upright position, the sliding roller 26 in the front and rear controller 12 is in the position of the knob position stopper 1.
3, the thread pincher 15 comes into contact with the knob position stopper 13 due to the rearward movement of the rotating shaft 22 by the push spring 21, and the thread pincher 15 is located at the foil thread 14 picking position. Then, when the rotating arm 24 of the yarn feeder 11 rotates and starts moving toward the loom from the upright position, the front and rear controller 12 rotates in the same direction as the rotating arm 24, and the Sakayabu roller 26 rotates. It is displaced from the position of the knob position stopper 13 to the position of the position adjuster 9, and comes into pressure contact with the front surface of the plate-shaped portion of the position adjuster 9 based on the action of moving the rotary shaft 22 in the rearward direction by the push spring 21.

16 is a weft guiding spatula for pulling the foil yarn 14 into the sugiguchi, 1
7 indicates a hole in the spatula 16 for inserting and guiding the foil thread 14.

The longitudinal position of the spatula 16 when the batten 1 is stopped at the position closest to the fabric front and the thread picker 15 when the rotating arm 24 of the thread feeder 11 is in the upright position and the thread picker 15 is in the picking position of the foil thread 14. are the same. A large number of foil threads 14 are arranged side by side in the left-right direction on a thread holder (not shown) installed above the side of the loom, with one end protruding from the thread holder towards the loom. , a lo-hoo feeder (not shown), etc., each foil yarn 14 is sequentially fed to a predetermined position, that is, a picking position, according to its order. The one shown in FIG. 4 is another embodiment, which includes a mounting bracket 3 for adjusting the pivot connection position of the rod 4 to the thread sword 2, and a cam 5.
is formed on the lower part of the free end side of the rod 4 as a rearwardly upwardly inclined surface, and the position where the arm having the roller 6 at the tip of the shaft 8 and the position adjuster 9 are provided at right angles. A push spring 21 is interposed between the rear side shaft bearing part of the underframe 23 and a collar 20 that fixes the rotating shaft 22 at an appropriate position to push the rotating shaft 22 forward. In this way, the front/rear controller 12 is brought into contact with the rear surface of the plate-shaped portion of the position adjuster 9. Therefore, in the present invention, when the rotating arm 24 of the yarn feeder 11 is in an upright state, the Sake roller 26 of the front-rear controller 12 assists the knob position stopper 13, so that the position of the rotating shaft 22 in the front-rear direction is controlled. As a result, the thread pincher 15 is positioned at the foil thread 14 picking position and can pick the foil thread 14.

Then, when the rotating arm 24 rotates due to the operation of the drive rod 18 and starts to move toward the loom from the upright position, the sliding loaf 26 of the front and rear controller 12 is stopped at the knob position (the state shown in FIG. 1). 13 to the position of the position adjuster 9, and comes into contact with the front surface of the temporary portion of the position adjuster 9, which is moved back and forth corresponding to the stop position of the batten 1. For example, if the batten stops on the forward side, the position adjuster 9 is tilted toward the rear, and the push spring 21 causes the position adjuster 9 to move rearward together with the rotating shaft 22. The front/rear controller 12 will be in charge.

As a result, the thread pincher 15 of the thread feeder 11, which is moving toward the loom, changes its position to the front side in accordance with the stop position of the batten 1, and the positions of the thread pincher 15 and the spatula 16 in the front-rear direction. When the rotating arm 24 of the thread feeder 11 is tilted toward the loom, the foil thread 14a picked up by the thread pincher 15
This allows the material to be accurately fed into the hole 17 of the spatula 16.

In this way, the present invention allows the longitudinal position of the thread pincher of the thread feeder to correspond to the stop position of the batten, so that the foil yarn can be transferred to the twill thread no matter where the batten stops. It has a very beneficial effect of being able to reliably send it to the area. Further, in this invention, the foil yarn is fed in conjunction with the batten that moves frequently, but when the batten is in frequent motion outside of the foil yarn weft insertion work, the yarn feeder is Since it is not affected by baton movements, such as vibration and shaking, the entire device is less likely to break down or wear out, endure long-term use, and always operate accurately.
