DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a device for removing a miss thread in a shuttleless loom.

[Prior art] When a weft insertion error occurs in a shuttleless loom, the machine stop is performed based on a weft insertion error detection signal from a weft yarn detection sensor, and damage to each part rotating at high speed due to sudden stop is detected. In consideration of the above, the machine stops after the inertial operation of one or more turns of the machine. Therefore, in order to remove the miss thread, the machine base is reversed to release the gripping state by the warp, and then the finger or fork miss thread separating member is inserted between the cloth fell and the miss thread. (Japanese Patent Laid-Open No. 58-220856)
Reference).

However, since miss yarns are woven by the same wefting as normal wefts, it is difficult to separate them simply by releasing the gripping state with the warp yarns, and the maximum opening of the warp yarns formed during normal operation It has already been proposed to separate the erroneous yarn by forming an opening angle larger than the angle (see Japanese Patent Application Laid-Open No. 62-97944).

In the case of an already proposed type having an opening angle equal to or larger than the maximum opening angle of the warp formed during normal operation, not only a large power is required to increase the opening angle of the warp yarn, but also the entire opening angle is increased. Abnormal tension is applied to the warp yarn, and there is a problem that it is necessary to interlock with a feeding device or a winding device of a loom for adjusting the tension.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and it is possible to reliably grasp and separate a mistaken yarn and to attach it to a conventional shuttleless loom with an independent compact device. The purpose of the present invention is to provide a device for removing a miss yarn.

In order to achieve the above object, the present invention operates a gripping mechanism for a mistaken yarn, an entering mechanism for causing the gripping mechanism to enter the warp yarn opening, an advancing mechanism for advancing to the cloth fell, and retreating therefrom, and a gripping mechanism. In an error removing device in a shuttleless loom comprising an operating mechanism and control means for controlling these mechanisms, when the gripping mechanism grips the error yarn, the gripping portion and the opening state around the gripping portion are controlled by the gripping mechanism. A guide member for further opening the warp is provided.

Since a guide member for further opening the warp yarn in the normal open state is provided in the gripping mechanism for gripping the miss yarn, the gripping mechanism enters the warp yarn opening and moves to the cloth fell to grip the miss yarn. At the time of advance, the guide member pushes the warp yarn in the open state further upward and downward to advance, and the error yarn at the portion pushed by the guide member is easily separated from the cloth fell. The operation can be reliably performed by the operation of the mechanism.

The gripped erroneous yarn can be easily removed by withdrawing the gripping mechanism toward the reed and withdrawing from the warp yarn opening.

The guide member 5 is changed depending on weaving conditions such as the warp yarn density, the warp yarn tension, the number of weft yarns, and the width D (FIG. 4) of the guide member 5 determines the range in which the warp yarn is further opened. The opening angle α of the guide member 5 (FIG. 3) is determined by the position of the tip of the guide member 5 with respect to the nip point N (FIG. 2) of the grippers 2 and 3, and is compared with the opening angle θ in the open state of the warp yarn. The positions of both are determined so as to be larger.

When a weft insertion error is detected by a sensor (not shown), the weaving machine reversely rotates the looms and stops in a state where the erroneous yarn is not gripped by the intersecting warp yarns, that is, in a so-called spouted state. The small motor 6 is rotated by a signal from control means (not shown), and the gripping mechanism 1 is advanced into the openings of the warp threads T, T via the moving nut 9, the guide 10, the arm 12, and the tubular portion 13. Immediately after the small motor 6 is stopped, the air cylinders 14 and 16 are actuated, and the air cylinder 14 rotates the gripping mechanism 1 via the link 15, the spline shaft 11, and the arm 12 toward the cloth fell Fa below the cloth, On the other hand, the air cylinder 18 rotates the movable gripper 3 urged by the spring 4 of the gripping mechanism 1 via the link 19, the shaft rod 20, and the cam portion 20a to open the grippers 2, 3.

The rotation of the gripping mechanism 1 to the cloth fell Fa continues until the grippers 2 and 3 come into contact with the cloth fell, and is stopped by the contact. At the same time, the opening of the movable gripper 3 by the air cylinder 18 ends, and the grippers 2, 3 grip the foremost miss yarn Y by the action of the spring 4. When the gripping mechanism 1 rotates to the cloth fell Fa, the guide member 5 advances in the direction of the cloth fell Fa while pushing up and down the warp yarns around the grippers 2 and 3 and up and down. The missed yarn Y in the portion where is located is not restricted by the warp yarn at all,
And 3, the mistaken yarn Y is reliably held.

When the gripping mechanism 1 finishes gripping the miss yarn Y, the air cylinder 14 operates to move the gripping mechanism 1 in the direction of the reed. After the gripping mechanism 1 retreats and stops, the small motor 6 rotates in the reverse direction to retreat the gripping mechanism 1 out of the warp yarn opening.

According to the mistake yarn removing device in the shuttleless loom of the present invention,
When the gripping mechanism grips an error yarn, the gripping mechanism is provided with a guide member for further opening the warp in the gripping portion and its surroundings, so that the guide member enlarges the opening state of the gripping portion and the warp around the gripping portion. As a result, the erroneous yarn in the gripping portion is not subjected to the warp yarn constraint at all, and the gripping mechanism can reliably grip the erroneous yarn. And, in the mistake yarn removing device of the present invention, since only the opening angle of the warp around the grip portion and the periphery thereof is increased, it is possible to make an independent compact device without requiring a large power. It can be easily mounted on existing shuttleless looms.
