Description

Weft Cutting Machine for Fluid Spray Looms {Removal device for a waste weft}

The present invention is to be cut by holding the wefts protruding to the right side of the fabric of the fabric when weaving the fabric using a fluid jet weaving machine, such as water jet looms or air jet looms, and treated by holding the cut cutting yarn The present invention relates to a splitting device for a fluid spray loom, which is capable of holding and treating the end cutting yarn of the weft without the catch cord yarn opening movement. By maintaining the tension, it is possible to solve the problems caused by the non-uniformity of the weft force of the toilet.

In general, the end treatment of the weft when weaving the fabric using a water jet loom is made as follows.

That is, as shown in FIGS. 11 and 12, the weft yarn 100 is enclosed between the inclined portions 102 by which the weft yarn is opened, and the length of the weft yarn 100 being engraved is typically about 8 to 15 cm longer than the width of the fabric. It is taken in.

Therefore, the weft yarn 100 protruding out of the bow portion of the fabric 104 is gripped by the catch cord yarn 110 that is opened by the catch cord heald 112 and is cut by the cutting machine 108 and cut. Our yarn (cutting yarn) is grasped by the catch cord yarn 110 that is rotated by the spindle 114, twisted and transported out of the loom, where the catch cord yarn 110 is generally used in four or more strands, the four strands The catch cord yarn 110 is moved by the catch cord yarn heald 112.

However, the cutting yarn processing apparatus having such a configuration has the following problems.

That is, not only the four-ply catch cord yarn 110 inserted into the catch cord yarn heald 112 needs to be opened at every turn of the loom, and in the case of a dobby machine, only the catch cord yarn 110 must be separately opened. Two separate healds are required and careful work is required for the preparatory work and the four-ply catch cord yarn 110 for uniform tension management and prevention of trimming. In some cases, the end of the weft yarn 100 to be enclosed is There was a problem such that the interference to the catch cord company 110 causes a normal weaving.

The inventor of the present invention has invented and registered (Patent No. 250384) in order to solve the problems caused by the above-described processing apparatus.

In other words, when weaving the fabric using a water jet loom, the weft yarn protruding to the right side of the fabric edge is cut and treated with a catch cord yarn, so that the catch cord yarn does not move up and down and the body needle is formed by engaging the end of the rotating spindle. By moving the weft yarn that has been transported forward by the weft guide plate to the latching part of the spindle, the right end of the weft is wound around the catch cord yarn and drawn out to the outside, but the inertial body is formed on the back of the weft guide plate. During the needle movement, the inertial plate of the inertial body is projected to the front side of the weft induction plate by the inertia so that the end of the engraved weft can be securely caught in the engaging portion of the spindle.

Therefore, the processing apparatus of the above-described configuration has the effect of being able to solve the problem caused by the opening movement of the catch cord yarn by treating the upper cut and cut yarn without opening the catch cord yarn. It also had the following disadvantages.

In other words, the inertial body is fixed to the back side of the weft induction plate so that the end of the weft thread can be securely caught in the latching part of the spindle during the body needle movement. It is not possible to use it for a long time due to the impact, and it has to be replaced frequently, and it is insufficient to grasp the end of the insulated weft with a certain amount of tension in the early stage. There was room for defect.

The present invention allows to handle by holding the end of the weft without catching the catch cord yarn opening movement to hold the end of the weft weft in order to correct the problems of the prior art and at the same time to maintain a certain tension from the beginning of the weft weft By holding in one state to weaving is to be able to suppress the occurrence of defects of the fabric due to the irregularity of the gastric force.

In order to achieve the above object, the present invention installs a weft holder composed of a catch code yarn guide plate and a plurality of weft narrowing plates on one side of the weft sensing strip, and the catch code company guides the two strands through the catch code yarn guide plate configured in the weft holder. After passing through the guide to the spindle located in the rear, the body portion in contact with the weft holder is provided with a weft holder dedicated body.

The front surface of the dedicated body is formed with a ceramic coating layer to improve the contact friction force of the engraved weft so that the engraved weft can always maintain the tension force.

In addition, the catch cord yarn passing through the catch cord yarn guide plate is configured to be guided through the fixed slope at regular intervals up and down behind the weft holder-only body, so the catch cord yarn does not need a device for a separate opening movement.

According to the present invention configured as described above, the catch cord yarn 8 grips the cut yarn of the weft yarn 74 engraved during the weaving of the fabric using the fluid spray weaving machine to move out of the loom.

However, in the present invention, the catch cord yarn 8 can handle the cut yarn of the weft yarn 74 without opening movement, which not only simplifies the apparatus, but also the weaving is performed while the end of the weft yarn has always maintained a uniform tension. To make it happen.

In other words, the operation of the present invention will be described.

FIG. 1 is a schematic plan view showing the use state of the apparatus of the present invention. When the weft yarn 74 is inserted between the inclined yarns 82, the weft yarns 74 pass through the inclined yarns 82 and the catch cord yarn 8. The end of the weft holder dedicated body 22 is located in front.

In the above state, when the body 70, 22 moves forward by the body needle movement, the weft yarn 74 is moved to the immediately preceding side by the body 70 and the weft holder dedicated body 22. Since the ceramic coating layer 72 is formed on the front surface of the weft holder dedicated body 22 and the friction coefficient is high, the wet weft 74 soaked in water moves while maintaining the initial tension while being adsorbed by the weft holder dedicated body 22. do.

In the case of the air jet loom above, it is advantageous that the ceramic coating layer 72 is formed.

As the weft yarn 74 is led by the body 70 and the weft holder-only body 22 to advance, the weft yarn 74 is the catch cord yarn guide plate 42 and the first, second, third and fourth narrow plates of the weft holder 20. (54) (56) (58) (60) are guided by the bent portions (63) (64) of the catch cord yarns (8) (8 ') and pushed into the grips. The cutting yarn 75 which is completely gripped by the catch cord yarn 8 and 8 'which is rotated by the cutting cord and then cut and cut by the cutting machine 2 is loomed along the catch cord yarn 8 and 8'. Is managed out.

At this time, since the catch cord yarns 8 and 8 'do not have an opening movement, the catch cord yarns 8 and 8' do not require a complicated device according to the opening movement unlike the conventional art.

In other words, the catch cord yarns 8 and 8 'used in the present invention are separate opening movements because the catch cord yarns 8 and 8' are guided through the fixed yarn 80 spaced up and down at regular intervals. No need to do

At this time, even if the catch cord yarns 8 and 8 'are not opened, the enclosed weft yarns 74 are able to grip the end portions, so that the catch cord yarns 8' located at the bottom as shown in FIG. Directly connected to the spindle 10 via 80, the upper catch cord yarn 8 is guided down via the guide groove 46 of the catch cord yarn guide plate 42 configured in the weft holder 20 Since the guide hole 48 is then guided back toward the rear spindle 10, the catch cord yarn guide plate 42 of the weft holder 20 is in contact with the upper and lower catch cord yarns 8 and 8 '.

Therefore, the weft yarn 74 drawn by the weft holder dedicated body 22 toward the weft holder 20 is the catch cord yarn guide plate 42 and the first, second, third and fourth narrowing pieces 54, 56 and 58. When the weft holder-only body 22 continues to move forward in the above state, the weft yarn 74 slides downward along the curved portions 63 and 64, and the tension force is in contact with the curved portions 63 and 64 of the 60. It is sandwiched between the catch cord yarn (8) while maintaining the.

At this time, the end of the weft yarn 74 is adsorbed by the ceramic coating layer 72 formed on the front surface of the weft holder dedicated body 22, the weft holder dedicated body 22 in the above state advances the catch cord yarn guide plate 42 And the weft yarns 74 are bent in zigzag up and down as shown in FIGS. 2 and 7 by the bent portions 63 and 64 of the first, second, third and fourth nip pieces 54, 56, 58 and 60. Since the weft (74) located at the side of the fabric portion 84 is pulled to one side because it maintains a constant tension it is possible to prevent the weaving failure of the fabric due to the weft unevenness.

Since the ceramic coating layer 72 formed on the front surface of the weft holder dedicated body 22 is made of ceramic powder, it forms a fine uneven surface on the surface, so that the weft holder is increased by increasing the coefficient of friction in the state where the weft yarn 74 is adsorbed. When the weft yarn 74 is bent by the curved bodies 63 and 64 of the weft holder 20 by the dedicated body 22, a force to maintain the state in which the weft yarn 74 is adsorbed to the ceramic coating layer 72 is applied. It is possible to maintain a sufficient tension in the weft yarn 74, and when the weft holder dedicated body 22 is advanced, the weft yarn 74 is the catch cord yarn guide plate 42 and the first, 2, 3, 4 pincer plate The weft yarn 74 is inserted into the locking grooves 65 and 66 formed in the 54, 56, 58, and 60, even when the weft holder dedicated body 22 is retracted in this state. Will remain.

As described above, when the weft yarn 74 is gripped between the catch cord yarns 8, the catch cord yarn 8 continues to be twisted by the rotating spindle 10 to firmly grip the weft yarn 74, and at the same time, the cutter Cut by the (2), the cut yarn 75 of the cut weft is continuously discharged out of the loom along the catch cord yarn (8).

A plurality of through-holes 68 drilled through the weft holder dedicated body 22 is the catch cord yarn guide plate 42 and the first, second, and third configured to protrude into the weft holder 20 when the weft holder dedicated body 22 is advanced. , 4 sandwiching plate (54) (56) (58) 60 is to be fitted, so that the smooth operation is made.

Therefore, in the present invention, the catch cord yarn gripping the end of the weft projecting to the right side of the toilet seat during weaving of the fabric using a fluid jet weaving machine such as a water jet loom or an air jet loom can be handled by gripping the end of the weft without opening movement. In addition to simplifying the catch cord screw, it is easy to manage. Also, weaving is performed by keeping the tip of the weft with a constant tension to prevent weaving defects caused by non-weft force. It will be effective.
