Description

No-OPENING TYPE DISPOSAL DEVICE OF WEFT YARN END BEARING FOR WATER JET LOOM}

The present invention, while weaving the fabric using a water jet loom, the front end portion of the weft yarn that is longer than the right side deformed portion (the side where the weft sensor is installed) is held in the catch cord yarn, and the gripped weft yarn is cut by a cutter, In constructing the weft cutting yarn processing device of the waterjet loom which cuts the cut yarn (we) out of the loom through the catch cord yarn, in particular, the upper and lower catch cord yarns pass through the catch cord yarn dedicated body. By passing through the completely separated state of the by means of the act of clearly pushing the catch cord yarn to the gripping point of the catch cord yarn that does not open the movement without opening movement, the catch cord yarn always catch code It satisfies the function of the yarn and at the same time ensures that the spindle rotation is accurately transmitted to the catch cord yarn, Install a gripper which can grip an end to the force that is above ipgam of the weft, of course, to be shortly set up a wiip length allows the tension retaining the weft tip to reduce the loss of the weft, but one ensures stable fabric weaving.

In general, the treatment of the weft cutting when weaving the fabric using a waterjet loom is made as follows.

That is, as shown in Figure 18, the weft yarn 1 is enclosed between the inclined (2) opened by the injection water, the length of the weft yarn 1 engraved is usually engraved by about 10 ~ 15cm longer than the width of the fabric.

The encased weft (1) is detected by the weft sensor (4) while moving toward the fastball by the forward movement of the body (3), the front end of the weft fore weaving longer than the right edge of the fabric (5) It is a structure which is grasped by the yarn 6, cut by the cutter 7, and then passes through the slope 8 'configured on the catch cord yarn guide plate 8, and is guided to the spindle 9 again and drawn out of the loom. .

The catch cord yarn 6 passing through the catch cord yarn guide plate 8 is moved forward through a form in which opening movement is normally performed by lifting and lowering of a heald and a fixed top and bottom fixed rods fixed to the rear of the body. There are two cases in which the guide cord is always open, that is, the catch cord yarn does not move.

However, the weft tip processing apparatuses of the above structures had the following disadvantages.

First, a separate opening device is required for the opening movement of the catch cord yarn, or two healds for opening only the catch cord yarn must be added in addition to several heald frames for selectively opening the inclination according to the fabric structure. There were disadvantages such as complicated device.

As a means for compensating the above disadvantages, the present inventors have a catch cord yarn 110 using a fixed yarn 100 as in Patent No. 337599 "Weft Cutting Machine for Fluid Spray Weaving Machines" (see FIG. 27). Means have been provided to maintain the open state at all times, and to allow the catch cord yarn 110 to be joined by the catch cord yarn guide plate 130 configured in the weft holder 120.

Therefore, in the case of the above apparatus, since the opening movement of the catch cord yarn 110 is not necessary, the configuration of the opening movement apparatus can be simplified.

However, in the case of the device, the catch cord yarn 110 can be made to be forcibly made at a specific point through the catch cord yarn guide plate 130 of one side of the weft holder 120 composed of a plurality of sandwich plates in front of the spindle 140. It was constructed to be suitable for use in a structure. In the case of the device as well as the configuration is generally complex, the catch cord yarn dedicated body 150, a plurality of incision holes 151 through which a plurality of pinch plates formed in the weft holder 120 is drilled so as to shake violently during the forward movement of the weft. An unstable phenomenon occurred and there was a difficulty in commercialization.

In addition, the catch cord yarn dedicated body 150 passing through the catch cord yarn 110 in the device is a single through hole 152 is passed through the catch cord yarn 110 is guided, the single through hole 152 Through the upper and lower catch cord yarn 110 is passed through, it is a structure that is guided.

As a body device having a structure in which the catch cord yarn 110 passes through the single through hole 152 as described above, in a device that allows a gripping point to be formed through the slope of a flat catch cord yarn guide plate which is generally used, the weft tip end portion There was a lack of function to smoothly move to the gripping point.

Because the front end of the weft is located in front of the catch cord yarn only body, if the body drags the weft and moves forward, it is possible to move easily to the catch point near the catch cord. There is no means of giving.

In other words, the gripping point where the upper and lower catch cords meet is located in the center of the through hole of the catch cord yarn body through which the upper and lower catch cords pass simultaneously, and the weft tip part located in front of the holding point is located in the empty space of the through hole. As the weft tip is moved forward by the catch cord yarn-only body, the gap between the weft tip and the upper and lower catch cord yarns increases, and the weft tip of the tensioned state is moved Due to the phenomenon of being hit by the back of the hollow space part of the through-hole due to its own weight, it is impossible to force the weft tip part to the gripping point, so that the grip of the weft tip part by the catch cord yarn becomes unstable.

Second, as shown in FIG. 18, the catch cord yarn 6 passes through the catch cord yarn guide plate 8 configured in front of the spindle 9 in the process of moving to the spindle 9 after passing through the body 3.

The catch cord yarn guide plate 8 has a function of guiding the catch cord yarn 6 to the spindle 9 and a function of forming the gripping point 6 ′ on the catch cord yarn 6. do.

However, the space where the catch cord yarn guide plate 8 is installed is located in a narrow place of the path where the weft detector 4 and the spindle 9, the cutter 7, and the catch cord yarn 6 pass. It occupies a lot, causing a lot of inconvenience in fine adjustment, repair and replacement of such components.

In addition, as the catch cord yarn 6 passes through the catch cord yarn guide plate 8, frictional resistance is generated, and the rotation of the spindle 9 which imparts twist to the catch cord yarn 6 is smoothly performed because of the frictional resistance. Since it could not be transmitted, it was one of the causes of the error in the holding of the weft cutter.

Third, the catch cord yarn (6) on one side of the weft end of the appropriate means for holding the weft tip is insufficient to cause the shaking phenomenon of the weft tip is generated, so the length of the weft of the weft should be set long, so that the loss of the weft ( Weft cutting)

Fourth, due to the structural problem of the spindle 9 imparting twist to the catch cord yarn 6, all the passing lines of the catch cord yarn 6 passing through the spindle 9 are centered, that is, the hollow portion ( 9-1), or through the hole 9-3 of the plate (9-2) constituting the spindle (9) constituting the spindle 9 does not deviate significantly from the center portion, and then the hollow portion (9-1) ) To be drawn out of the loom.

That is, as shown in Figs. 25 and 26, the hook 9-4 is formed at the tip of the spindle 9, and the weft tip is hooked to the hook 9-4, and then wound around the catch cord yarn 6. The spindle 9 has been provided, but in this case, there is no means for stably catching the weft end of the spindle 9 in the locking hole 9-4.

Further, as shown in FIGS. 20 to 23, a plurality of through holes 9-3 are drilled through the flat plate 9-2 constituting the spindle 9, and the catch cord yarn 6 zigzags the through holes 9-3. Although the spindle 9 has been provided with a structure that allows the passage to pass through, the slip path occurs because the passage path of the catch cord yarn 6 passing through the spindle 9 does not substantially deviate from the center of the spindle 9. While not only the rotation of the spindle 9 can not be directly transmitted to the catch cord yarn 6, but also the phenomenon that the applied twist is released.

Further, the inventor turns the main body of the spindle 9 to form a spiral twist 9-5, as shown in FIG. 24, and then catches the thread 6 through the spiral, thereby grounding the spindle 9 Although the length is kept longer, in this case, the loosening phenomenon of the twist applied to the catch cord yarn 6 is somewhat reduced, but since the passing position of the spindle 9 of the catch cord yarn 6 is not far from the center. There was a slight deficiency to completely solve the twist applied by the spindle 9 and the loosening of the applied twist.

As described above, the spindle 9 of various configurations conventionally provided does not allow the rotation of the spindle 9 to be directly connected to the twist of the catch cord yarn 6, and thus is gripped by the twist of the catch cord yarn 6. The treatment of the weft cutter is not smooth.

Fifth, the catch cord yarn holding the tip and weft cutting yarn of the weft is installed as close as possible to the right edge of the fabric (5 '), so that the grip of the weft tip and weft cutting is made smoothly, It was helpful, but because of the structural problems of the spindle installed side by side with the catch cord yarn, there was a limit to the close installation of the catch cord yarn toward the right side edge of the fabric (5 ').

As described above, there have been various problems with the weft cutting yarn processing apparatus of the water jet loom, which has been conventionally provided.

The present invention in order to rectify the above-mentioned disadvantages of the conventional catch code yarns do not move the opening movement always in the open state, the front end of the weft is moved by the forward movement of the body to the gripping point of the catch cord yarn to hold the weft end portion At the same time, the catch path of the catch cord yarn is simplified, providing more space on the weft sensing side to facilitate the adjustment and repair of related parts, and the rotation of the spindle is completely transmitted to the catch cord yarn by twisting. The weft cutting process is made smoothly, and the weft tip part is forcibly gripped, and the catch cord yarn is placed as close as possible to the right side of the fabric, reducing the loss of the weft yarn and smooth weaving. It was made possible.

As a means for solving the above problems, the present invention, in forming a weft cutting yarn processing apparatus of the water jet loom, the upper and lower catch code by forming a separating body flesh in the center of the catch cord yarn guide hole configured in the catch cord yarn dedicated body The thread passes through in a completely separated state to the left and right, and forcibly moves to the catch cord yarn gripping point by the separating body flesh when moving the enclosed weft tip portion forward, so that the smooth gripping is achieved, and the catchco positioned in front of the spindle By omitting the configuration of the guide plate and moving the spindle tip to the position of the fastener so that the position of the spindle tip does not collide when the body is advanced, the catch cord thread passing through the body is guided directly to the spindle on which the hollow part is formed. Catch cord yarn guided into the hollow is guided into the hollow part and then guided out through the front through hole. The catch cord yarn guided to the outside is turned around the outer surface of the spindle and then guided back into the hollow part of the spindle through the rear through hole to be drawn out of the loom. If you want to do so by installing the installation position of the spindle at an angle so that the position of the front end of the spindle as close as possible to the weft detector, it is possible, and the gripper is installed on one side of the spindle is configured to hold the weft end.

According to the present invention, in the weft cutting yarn processing apparatus of the water jet loom, even when the catch cord yarn is always open, the weft tip portion can move forward to the catch cord yarn gripping point precisely, so that the weft tip portion is held by the catch cord yarn. , The catch cord thread passed through the body is directly connected to the spindle, simplifying the movement path, and by installing the spindle at an angle so that the position of the spindle tip is installed close to the weft detector, By moving to close to the position of the fasteners, the body passing position of the catch cord yarn can be moved to the right side edge of the fabric, and the gripper is installed on one side of the spindle to compose the weft tip forcibly. In order to reduce the loss and to make the sense of position of the weft clear, After passing through the body, the catch cord that is guided directly to the spindle is moved as far away from the center of the spindle as possible so that the rotation of the spindle is transmitted as a twist of the catch cord. Of course, there is an effect such that the weaving can be made smooth.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 is a plan view, a perspective view, and a state of use of the weft cutting yarn treatment apparatus of the water jet loom to be provided in the present invention, a conventional weft yarn on one side of the right side deformation portion (C-1) of the fabric (C) The cutter 10 and the weft sensor 20 are provided, and the spindle 30 for providing twist to the catch cord yarn W-1 is provided on the side of the weft sensor 20.

On the front surface of the spindle 30, the catch cord yarn-only body 70 is installed in parallel with the inclined body 40, the catch cord yarn-only body 70 constitutes a guide hole 71 and a fixed yarn ( 72, the upper and lower catch cord yarn (W-1) is passed through, but the guide hole 71 is installed in the center portion of the separating body flesh 73 so that the guide hole 71 is separated from side to side, and then fixed The upper and lower catch cord yarn (W-1) passing through the dead road 72 is passed through the guide hole 71 in a state completely separated from the body body 73 for separation.

At this time, the separation body flesh 73 may be installed side by side with the catch cord yarn dedicated body 70, but in the present invention was configured to be moved to the rear slightly as shown in FIG.

In this way, when the separating body flesh 73 is slightly rearward, the tip end of the weft yarn W-2 comes into close contact with the grip point of the catch cord yarn W-1, thereby increasing the holding time for a more reliable grip. It is to let.

However, even when used as a catch cord yarn dedicated body (70 ') using a general inclined body instead of the catch cord yarn dedicated body 70, as shown in Figure 17, the gripping function is slightly lower than the above but used according to the type of weft It could be.

Spindle 30 is installed side by side parallel to the inclined (W) as shown in Figures 5 and 6 or obliquely installed so that the tip end of the spindle 30 toward the weft sensor 20 as shown in Figures 7 to 9. Can be used.

In addition, the position of the front end of each spindle 30, the catch cord yarn (W-1) passing through the body 40 to the front as close as possible so as not to hit the front of the body 40 when passing the catch cord yarn It is guided directly to the spindle 30 without passing through the guide plate (not shown).

The structure of the spindle 30 used in the present invention is composed of a tubular body 33 in which the hollow part 31 is formed, as shown in FIGS. 15 and 16, and through holes 32 in the longitudinal direction in the body 33. ) Is open.

At this time, at least two through holes 32 to be drilled in the spindle body 33 are to be drilled, and the front through hole 32-1 is drilled on the front end side based on the main body 33, and the rear through hole on the rear end side. (32-2) is open.

The cross-sectional shape of the main body 33 of the spindle 30 may be formed in a circular shape, or may be manufactured and used in various forms such as an ellipse and a polygon, except that the main body 12 having a hollow part 31 is formed, and the main body At 12, at least two through holes 32 are formed in the longitudinal direction.

In this case, the hollow portion 31 formed in the main body 21 may be formed only at a portion through which the catch cord yarn W-1 passes, and a hollow portion must be formed at a portion where the catch cord yarn W-1 does not pass. There is no problem in use even if the inside of the main body 33 is blocked without the need of forming the 31.

Therefore, the catch cord yarn W-1, which is directly guided to the spindle 30 after passing through the body 40, is guided into the hollow portion 31 at the tip of the spindle 30, and then the front through hole 32-1. Guide the outside through the catch cord yarn (W-1) is to turn the outer surface of the body 33 again and then guided back to the hollow portion 31 through the rear through hole (32-2) out of the loom To be withdrawn.

In addition, the catch cord yarn (W-1) is advantageously installed close to the right side deformation portion (C-1) of the fabric (C), but in the currently installed state due to a component such as a bracket (36) supporting the spindle (30). It is a structure that can no longer be installed close to the weft sensor (20).

However, when the spindle 30 is inclined as shown in FIGS. 7 to 9, the front end position of the spindle 30 can be installed close to the weft detector 20, so that the body 40 of the catch cord yarn W-1 can be installed. It is advantageous to reduce the loss of the weft because the passing position can be installed close to the right side edge portion (C-1) of the fabric (C).

Even when the spindle 30 is inclined as described above, the catch cord yarn W-1 passing through the body 40 is directly connected to the spindle 30, and the passage path of the spindle 30 is the same as described above.

On the side of the spindle 30, a gripper 50 capable of forcibly holding the tip of the weft yarn W-2 is provided.

The gripper 50 is composed of a lower fixing plate 51 and an upper movable plate 52, as shown in Figure 14, the fixing plate 51 and the movable plate 52 is a fastening portion 61 bent at one side of the fixing plate 60 ) To be fixed to the fixing plate 51 at the lower end of the fastening part 61 with the fixing bolt 54, and then the movable plate 52 is positioned on the fixing plate 51, and then to the shaft bolt 55. It is installed to be movable on the side of the fastening portion (61).

At this time, the ground plate 53 is formed between the upper surface of the fixed plate 51 and the lower surface of the movable plate 52, and the upwardly inclined surface 56 and the downwardly inclined surface 57 are formed at the front end of the fixed plate 51 and the movable plate 52. The movable plate 52 is configured to be elastically installed on the fixed plate 51 while being supported by the tanger spring 58 fixed to one side of the fastening portion 61.

Reference numeral 80 is a temple bar, 81 is a guide roller.

In the present invention configured as described above, the weft yarn (W-2) is enclosed between the inclined (W) opened when weaving the fabric (C) using the waterjet weaving machine, and the weft yarn (W) in which the body 40 is advanced and enclosed in the above state. In the process of pushing -2) to the fastener (C-2), the weft sensor 20 detects whether the weft is inclined, and the body 40 which moves the weft yarn (W-2) to the fastener (C-2). It is the same as the conventional that the weaving of the fabric (C) is made by the repetition of the backward movement (body movement), but in the present invention the catch cord yarn (W-1) dedicated body only catch cord yarn By 70, the weft tip portion can smoothly move to the catch cord yarn gripping point C ', simplify the movement path of the catch code yarn W-1, and at the same time catch code yarn W-1. The body 40 of the passing position can be installed close to the side of the deflection (C-1), and also the rotation of the spindle 30 is the twist of the catch cord yarn (W-1) In order to ensure that the weft tip end is securely transmitted, the gripper 50 is installed on the spindle 30 side to force the weft tip part so that the proper tension is maintained at the weft tip end even when the inlet length is reduced. It is to reduce the loss of weft.

That is, the means for smoothly moving the weft tip portion to the gripping point C 'even when the catch cord yarn W-1 is always opened is as follows.

The catch cord yarn (W-1) is to be guided to the guide hole 71 of the catch cord yarn dedicated body 70 in the state opened through the fixed yarn 72, the upper and lower catch cord yarn 70 guide ( 71) Completely separate the left and right through the separation body flesh (73) located in the center and then guided to the spindle (30).

In the above state, when the weft yarn W-2 is enclosed between the opened inclination W and the catch cord yarn W-1, the tip of the weft yarn W-2 is located in front of the catch cord yarn-only body 70. In the above state, when the body 40 and the catch cord yarn dedicated body 70 move forward, the weft yarn W-2 moves forward together.

As described above, when the distal end of the weft moves forward and close to the grip point C 'of the catch cord yarn W-1, the gap between the upper and lower catch cord yarn W-1 is narrowed, and the weft yarn W-2 is moved. ) The distal body 73 located in the center of the guide hole 71 of the catch cord yarn-only body 70 is discontinued as the tip part contacts the upper and lower catch cord yarns (W-1). Since the fork tip ends to move forward and is forcibly moved to the gripping point (C '), the tip of the weft (W-2) can be brought into close contact with the gripping point (C') of the catch cord yarn (W-1). The grip of the weft tip by the catch cord yarn (W-1) can be made clearly without error.

At this time, the separation body flesh 73 formed in the center of the guide hole 71 of the catch cord yarn dedicated body 70 is located behind the inclined body 40 is the grip point of the catch cord yarn (W-1) (C ') is to be formed closer to the body 40 than the fastener (C-2), so that the holding time of the holding end of the weft tip by the upper and lower catch cord yarn (W-1) can be made long.

In addition, the movement path of the catch cord yarn (W-1) passes through the catch cord yarn dedicated body 70, as shown in Figure 5 and then the spindle 30 without passing through the catch cord yarn guide plate (not shown) as in the prior art By connecting directly to the simplification of the movement path, the catch code yarn (W-1) can be easily installed.

In particular, when the spindle 30 is inclined as shown in FIG. 7, the position of the tip of the spindle 30 may be installed close to the weft detector 20, and the catch cord yarn W-1 guided side by side to the spindle 30 may be used. It is effective to close the passing position of the weft yarn (C-1) to the grip of the weft yarn (W-2) is made more advantageous, as well as to reduce the weft length of the weft yarn.

In addition, in the present invention, the rotation of the spindle 30 is accurately transmitted to the catch cord yarn (W-1), so that the catch and cut yarn processing of the weft tip portion by the catch cord yarn (W-1) can be performed smoothly.

In other words, the structure of the spindle 30 used in the present invention constitutes a hollow portion 31 at a portion through which the catch cord yarn W-1 passes in the main body 33, and at the same time a through hole (before and after the main body 33). 32), the passage path of the catch cord yarn W-1 passing through the spindle 30 is guided into the spindle 30 through the hollow portion 31 formed at the distal end of the spindle 30. The catch cord yarn W-1, which is pulled out of the spindle 30 through the front through hole 32-1, and pulled out of the spindle 30, rotates the outer surface of the main body 33 of the spindle 30. After the back through the hole 32-2 is guided to the hollow portion 31 in the spindle 30 to be drawn out of the loom.

Therefore, in the above case, the catch cord yarn W-1 drawn out to the outside through the front through hole 32-1 during the passage of the catch cord yarn W-1 passes through the spindle 30. The ground length between the catch cord yarn (W-1) and the spindle main body (33) outer surface becomes as long as possible while turning the outer surface of the main body (33) to be guided to the rear through hole (32-2). Since the passing path of the catch cord yarn (W-1) is as far as possible from the center as far as the outer diameter of the spindle 30, the width of the bend becomes large.

As described above, the catch cord yarn W-1 passing through the spindle 30 has a longer grounding length with the spindle 30, thereby increasing the friction coefficient and being as far away from the center of the spindle 30 as possible. Since the bend passes in the maximum given state, the rotation of the spindle 30 is transmitted to the catch cord yarn W-1 without being slipped by twisting.

For example, if the rotation speed of the spindle 30 is 100 revolutions, the twist applied to the catch cord yarn W-1 is also given 100 times.

In addition, the catch cord yarn W-1 guided to the spindle 30 is guided into the spindle hollow portion 31 without passing through the catch cord side plate as in the related art, while the spindle 30 as shown in FIGS. 10 and 11. The gripping point (catch cord yarn opening point C ') is formed at the distal end portion, but the spindle 30 is directly transmitted to the catch cord yarn W-1 without losing the rotation of the spindle 30 so that the twist is applied. 30) The catch cord yarn gripping point C 'formed at the tip end is positioned slightly forward of the body 40 than the fastener C-2 at which the inclination W intersects.

Therefore, the weft yarn (W-2) is enclosed between the inclined openings (W), and then the weft yarn (W-2) moves toward the fastener (C-2) and the catch cord yarn holding point (C ') by the advancing of the body (40). In the process of movement, the tip of the weft yarn (W-2) first arrives at the catch cord yarn holding point (C ') and is forced to be in close contact. At the same time, the weft tip portion is gripped by the twist of the catch cord yarn (W-1). The gripped weft tip is cut by the cutter 10, and the cut weft cut yarn (used) is drawn out of the loom along the catch cord yarn W-1.

In addition, in the present invention, the catch cord yarn guide plate positioned at the distal end of the spindle 30 is omitted as in the related art, thereby simplifying the configuration and providing a space as compared with the configuration in which the spindle 30 protrudes forward. The handling of peripheral parts can be made conveniently.

Particularly, in the present invention, the gripper 50 is installed on the side of the spindle 30 so that the tip of the weft thread is forcibly gripped, so that the necessary tension can be maintained at the tip of the weft tip even if the length of the weft is reduced.

In the gripper 50, the movable plate 52 is supported by the tanger spring 58 on the fixed plate 51, and the lower surface of the movable plate 52 and the upper surface of the fixed plate 51 elastically contact each other. Since the holding part of the weft (W-2) is held by the ground portion 53, the holding force of the weft (W-2) can be increased, and the inclined plate (51) and the movable plate (52) at the tip of the upward inclined surface (56). And a downward inclined surface 57 is formed to stably guide the weft yarn W-1 moving forward by the catch cord yarn-only body 70 into the ground portion 53 of the gripper 50.
