Abstract
In the conventional weft pushing device, there is a problem such as the weaving of the weaving machine (JET) or the cutting of the weft due to improper detection and combination of improper detection and combination, such as interfering with weft insertion and pushing the weft immediately after the insertion.
The present invention supports the lower portion of the shaking plate (pin) which can swing in the same direction as the body needle direction on the weaving line 19 side of the body 3 and the upper part to stand so that the body 3 is inertia of the body needle movement. The weft yarn 2 immediately after the injection insertion from the nozzle is moved forward from the nozzle to the hook portion 7a of the weft detector 7 and the hook for the weft catcher provided separately from the weft detector 7. The arm 4 pushed toward and the corresponding arm 4 are urged back to the retreat direction to retreat from the insertion path of the weft thread 2 to the body 3 side when the weft thread 2 is inserted. (4) The weight 23 at the tip increases the inertia force that pushes the weft thread 2 by varying the weight depending on the thickness of the thread, and firmly pushes the hook portion 7a, and also the iron piece 21 on the arm 4. ), The weft detection is secured by attaching the sensor 22.
Description
The present invention relates to a weft inlet device of a jet loom, and more particularly, a jet loom such as a water jet or an air jet weft together with a fluid by water or air from a nozzle (NOZZLE) across a slope opened by an opening motion. The present invention relates to an improvement of a device in which weft is injected into the weft between the warp yarns.
Jet looms, such as water jets and air jets, inject water or air fluid from the nozzles along the inclined side opened by the opening motion, and float the wefts measured by the required amount (length) every time. Arm) which pushes the weft thread inserted from one side of the loom and immediately after insertion into the hook part of the weft detection device and the hook part which hangs the weft thread, and the forward movement end of this arm. The stopper which regulates the pressure of the arm repulses the arm in the retreat direction, and retracts the weft from the weft inlet to the body side when the weft is inserted. Weaving the fabric by repeating the body needle action to push.
In order to detect the insertion or miss (err) of the weft thread under the above conditions, a weft detection device is provided on the opposite side of the nozzle, and the presence of the weft thread is not confirmed by confirming the presence of the weft insertion immediately after the insertion by the device. At that time, the operation of the loom is stopped.
The present invention relates to an active weft inserting device improved to accurately detect the weft by increasing a certain amount of weft pushing in a jet loom capable of pushing the weft immediately after the weft inserting into a weft detecting device or the like.
In the conventional weft inserting device, the weft thread is caught by the hook due to the lack of pushing, or the weft thread is cut in the case of a thin thread. Timing passing through the detection unit and a timing sensor of the crank axis are performed in combination, resulting in inadequate movement of the arm (err, miss).
According to the present invention, when the arm pushes the weft end in order to achieve the above object, a weight is applied to the tip portion of the arm to change the inertia force according to the thickness of the weft. I made it to change the size.
Moreover, although the pushing distance was 6-7 mm conventionally, weight installation is also needed in order to shift the position of a stopper, and to raise the inertia force to push more than that.
As a result, the tip portion of the thread drawn from the side of the weft thread tends to have a low tension. As the amount of the pushing force increases, the tension of the tip portion increases and the entire width becomes a constant tension.
In the present invention, when the weft detecting device detects the weft, when the weft passes through the detection unit, it is combined with the signal of the signal generator set once in one rotation of the crank axis, and in this case, the free arm As a result, the timing at which the weft passes through the insertion detection unit may be shifted.
Nevertheless, the sensor detects the passage of the weft of the arm by the movement of the arm and combines the signal of the signal generator of the crankshaft and the signal of the arm. It is meant to be built.
The hook portion of the weft detector immediately after insertion increases the force to push the hook portion of the weft detector and the hook portion to hold the weft, thereby making it possible to secure the hook portion and increase the weft force.
The weft detection of the jet loom is accurate, and it is possible to provide a weft pushing device that can reduce the notice that the loom is stopped for no reason.

In addition, to increase the inertia force of the arm (4), it is better to make the arm (4) itself heavy, but weighting is not good because it is obstructed by weft insertion because the arm (4) becomes large.
Therefore, the inertia force can be efficiently increased by installing the weight on the tip of the arm.
