Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a weft storage device in a shuttleless loom.

(Prior art) In general, in shuttleless machines, especially in fluid injection type IIAn machines, it is necessary to measure and store a predetermined amount of weft supplied from a weft supply source each time weft insertion is performed. Conventional length measuring devices include a so-called air-boole type length measuring device in which the length of the weft is continuously measured by a length measuring roller ilI and is ejected from a storage nozzle into a storage pipe and stored, and a length measuring device in which the weft is wound around a drum. A so-called drum-boule type length measuring device that measures and stores the length using a drum is generally employed.

However, in the air-boole system sub-commander device,
Since the weft yarn is stored by air in an almost U-shape along the direction of the storage pipe, when the weft yarn is pulled out during weft insertion, it goes against the air jet from the storage nozzle, which increases the resistance of the weft yarn to be pulled out. As the weft becomes larger, the pull-out resistance differs greatly between when the weft starts being pulled out from the storage pipe and when the weft is almost finished being stored in the storage pipe, and the tension of the weft changes significantly. Therefore, the weft that is injected from the weft insertion main nozzle into the weft guide path formed by the rows of weft guide members arranged in parallel on the slay is likely to have flight defects, and the weft guide members The weft yarn may come out during weft insertion from the slit provided in the weft for weft escape during beating, or the weft yarn may form a loop in the guide passage, causing a mistake in weaving. There is a problem that it adversely affects the quality of the cloth.

In addition, since the resistance when pulling out the weft yarn from the storage pipe is large, it is necessary to increase the injection pressure of the main nozzle for weft insertion to increase the weft propulsion force, resulting in increased consumption of compressed air and, furthermore, weak yarn strength. There is a problem in that the weft yarn breaks in the main nozzle for inserting the weft.

Furthermore, in the drum boule type weft yarn length measuring device, when the weft yarn that has been wound and stored on the drum is pulled out, ballooning occurs and the pull-out resistance of the weft yarn becomes large. Therefore, as with the length measurement Bfl of the air bubble method, it is necessary to increase the injection pressure from the main nozzle for weft insertion to increase the weft propulsion force, which causes problems such as increased consumption of compressed air and further weft breakage.

A weft storage v1 arrangement for solving this problem is disclosed in Japanese Patent Laid-Open No. 57-95349. In this storage device, as shown in FIG. 15, the weft yarn Y is blown from a storage nozzle 4 onto the outer surface of an air-permeable endless belt 3 stretched between a driving roller 1 and a driven roller 2.
The weft yarn Y sprayed onto the outer surface of the belt 3 is suctioned and adhered to the outer surface of the belt 3 by a suction device 5 provided on the inner circumferential side of the belt 3, and as the belt 3 runs, the weft yarn Y is attached to the outer surface of the belt 3. It is deposited on top in a coiled form.

According to this weft storage device, the weft Y is only attached and stored on the outer surface of the belt 3 in the form of a coil.
There is little resistance when the weft yarn is pulled out from the surface of the belt 3 during weft insertion, and this reduces the problems such as increased compressed air consumption and weft breakage, which were problems with the air bouquet or drum bouquet length measuring devices mentioned above. The problem will be resolved.

However, although it has such advantages, the storage device has the following defects.

In other words, since the weft is linearly attached and stored on the belt 3 in a coiled state, the weft is not drawn out from the belt 3 in the same state during weft insertion, which eliminates fluctuations in the drawing resistance. I can't. Therefore, the weft insertion state is not stable, which adversely affects the quality of the woven fabric. In addition, since the belt 3 runs at a constant speed, it is extremely difficult to press and lock the weft yarn on the belt 3 and store the length necessary for one weft insertion. Even after all of the stored wefts have been pulled out, the wefts are directly pulled out from the storage nozzle 4 and inserted.In other words, when the wefts are pulled out from the belt 3 in an almost unrestrained state, the weft insertion speed from the storage nozzle 4 is The withdrawal speed of the weft suddenly decreases, and a large impact is applied to the flying weft yarn.As a result, the weft yarn flies out from within the weft guide path formed by the row of weft guide members during weft insertion. Sorry for making a mistake.

(Problems to be Solved by the Invention) In other words, in a weft storage device that ejects weft from a storage nozzle onto the storage portion of a weft storage body to which the weft is attached and stores the weft, the fluctuation of the weft withdrawal resistance during weft insertion; The present invention aims to solve the problem of the difficulty in obtaining a weft storage amount equal to the weft insertion length, and by solving these problems, fluctuations in weft pull-out resistance can be eliminated and the weft yarn can be always kept at an appropriate level. It is possible to ensure a good weft insertion condition and obtain high quality woven fabric.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an annular shape for adhering and storing the wefts in the path of the wefts whose lengths are measured and sent out from the weft length measuring section. A weft storage body having a weft storage part is disposed, the weft is ejected toward the annular weft storage part, and a spout is rotated in the circumferential direction of the storage part in synchronization with the rotation of the machine base. The weft storage device was constructed by providing a movable storage nozzle and a weft locking mechanism for pressing and locking the weft onto the storage section at at least one location on the weft storage section.

(Function) In other words, the weft yarn measured and sent out from the weft length measuring section is ejected from the storage nozzle whose spout moves in the circumferential direction of the annular weft storage section toward the weft storage section. As the outlet moves, the weft is attached and stored in a coil shape on the annular weft storage section. Then, the weft that is attached and stored in a coil shape on the weft storage section is pressed and tied by the weft locking mechanism on the weft storage section, and when the weft is pulled out from above the weft storage section by the length of the weft insertion, The drawing is stopped by the weft locking mechanism. That is, the weft thread is drawn out from the annular weft storage section in the same state until the end of weft insertion, and fluctuations in the drawing resistance are eliminated.

(Embodiment) Hereinafter, an embodiment embodying the present invention will be described based on FIGS. The weft Y whose length is measured by the length measuring roller machine 13 is guided to the weft storage device 14.The length measuring roller machine 113 is continuously driven in synchronization with the rotation of the machine. Drive O-ra 15
The weft yarn Y is wound around the driven roller 16 and the guide groove 17a, and the weft Y is wound around the driven roller 16 and the guide groove 17a. As the weft yarn Y rotates, the weft yarn Y is continuously pulled out from the cheese 11 at a constant speed and sent out to the weft storage device 14 side.

Next, to explain the weft storage section @14 in detail, as shown in FIG. 2, a bifurcated support bracket 18 is fixed to the side frame (not shown) of the loom, and its pair of arms 19. Support cylindrical parts 19a and 20a having the same axis in the horizontal direction are formed at the upper end of the support cylinder 20, respectively. A nozzle main body 21 is fitted into one support cylindrical portion 19a, and is fastened and fixed by a screw 22 threaded through the side peripheral surface of the support cylindrical portion 19a. A yarn guiding needle 23 is screwed into the rear end of the nozzle body 21 (the left end in FIG. 2), and an annular air passage converging toward the front is formed between the nozzle body 21 and the yarn guiding needle 23. T is formed and 1. The passage T communicates with an air supply pipe 24 screwed onto the side peripheral surface of the support cylindrical portion 19a.

Further, an air guide tube 25 is fitted and fixed at the tip of the nozzle body 21 so as to communicate with the air passage T, and a metal 26 is joined.

A thread guide tube 27 is rotatably mounted on the other support cylindrical portion 20a of the support bracket 18, and its rear end is joined to the metal 26. A driven pulley 28 is tightened and fixed on the outer periphery of the thread guide tube 27 between the supporting cylindrical parts 19g and 20a with a screw 29, and as shown in FIG. A driving pulley 3'1 fixed to a rotating drive shaft 30 is operatively connected by a timing belt 32. A nozzle tube 33 whose tip end is folded back into a semicircular shape is fitted and fixed to the front end of the thread guide tube 27 . That is, the nozzle body 21, the thread guide needle 23, the metal 26, the thread guide tube 27, and the nozzle tube 33.
A storage nozzle N that can rotationally move the injection port 33a is configured.

In front of the nozzle pipe 33, a disk-shaped weft storage body 34 is supported and erected by a bracket 35 attached to the side frame. The nozzle pipe 3 is on the #J side of the storage body 34.
The moquette 36 is centered around the insertion hole 34a for inserting the moquette 36.
The weft storage section 34b is formed by planting the weft yarns in an annular shape. The spout 33alfi of the nozzle pipe 33, whose tip end is folded back into a semicircular shape, is oriented in a direction substantially perpendicular to the weft storage section 34b in the vicinity of the weft storage section 34b.

A cam plate 37 is fastened to the circumferential surface of the distal end of the fiber pipe 27 by screws 10, and a pair of first cam plates 37 are provided near the top and bottom of the cam plate 37. The second weft locking bodies 38 and 39 are 1
The rotors 38a and 39a, which are rotatably supported by shafts 40 and 41 with a phase difference of 80 degrees, and which are installed in both the thread locking bodies 38 and 39, respectively, are connected to cams by springs 42 and 43, respectively. It is pressed onto the cam surface of the plate 37. The tips of the first and second weft locking bodies 38 and 39 are bent at a substantially right angle toward the center of the weft storage body 34 on the front side of the peripheral edge of the weft storage body 34, and the weft locking parts 38b
, 391) are formed. And rotor 38a
, 39a are located in the troughs on the cam surface of the cam plate 37, the weft locking portions 38b.

39b comes into contact with the weft storage section 34b where the moquette 36 buzzes in accordance with the movement locus of the spout 33a of the nozzle pipe 33,
When the rotors 38a and 39a are located at the peaks on the cam surface, the weft locking parts 38b and 39b are moved away from the weft storage part 34b to a position where they do not intersect with the spout 33a. In this embodiment, the weft binding portions 38b and 39b of the first and second weft binding bodies 38 and 39 are alternately in contact with and separated from the weft storage portion 34b for one rotation of the cam plate 37. , the cam plate 37 and the nozzle pipe 33 are configured to rotate one-half rotation per one rotation of the machine.

Now, the weft yarn Y whose length is continuously measured and sent out from the length measuring roller mechanism 13 as the loom is operating is caused by the air flow that is injected from the air supply pipe 24 through the air passage T into the air guide thread 25. The weft storage section 3 is propelled from the injection port 33a.
It is ejected onto 4b.

At this time, the jetted air is blown to the weft storage section 34b, but since the storage section 34b is formed by the moquette 36, the jetted air passes between the moquettes 36 and is directed toward the plane of the weft storage body 34. As a result, only the weft yarn Y is deposited on the weft storage section 34b. Then, the nozzle pipe 33 rotates and the injection port 33a is inserted into the annular weft storage section 34.
As it moves in the circumferential direction of b, the weft Y moves to the weft storage section 34
It is attached and stored in a circular arc on the weft yarn storage section 34b, and is also twisted into a coiled state and attached on the weft storage section 34b.

As shown in FIG. 3, when the spout 33a of the nozzle pipe 33 passes through the first weft locking body 38, the rotor 38a immediately moves to the trough on the cam surface of the cam plate 37, and the weft locking portion 38
b is pressed into contact with the weft storage part 34b by the action of the spring 42, and the weft adhered and stored on the weft storage part 34b is pressed and locked onto the weft storage part 34b by the weft locking part 38b. At this time, the rotor 3 of the 211th thread locking body 39
9a has moved to the mountain part of the cam plate 37, and the weft thread locking part 3
The press locking of the stored weft by 9b is released.

Then, the gripper 44 shown in FIG. 1 is opened in synchronization with the weft insertion timing, and the weft insertion main nozzle 45 is operated. The weft Y attached in a coil shape on the annular weft storage section 34b passes through a yarn guide 46, a gripper 44, and a yarn guide post 47 provided at the rotation axis of the nozzle pipe 33 in front of the weft storage device 14. Then, the weft is guided to the main nozzle 45 and is injected from the main nozzle 45 into a weft guide path S formed by a row of weft guide members 94 arranged in parallel on a sleigh (not shown). Then, the weft yarn Y attached and stored on the weft storage section 34b is pulled out until it reaches the locking position by the weft locking section 38b, and the insertion of the weft yarn is completed.

When the machine rotates once from the state shown in Fig. 3, the nozzle pipe 3
3 rotates by 1/2 from the position shown in the same figure, and the spout 33a passes through the second weft stopper 39.

Therefore, the weft Y having the length of one weft insertion is attached and stored between the first and second weft locking bodies 38 and 39 on the weft storage section 34b, and is pulled out and tightened in the same manner as described above. Ru.

The tip of the flying weft yarn Y shows a flying state as shown by a curve C in FIG. In the figure, θ1 represents the machine rotation angle when the gripper 44 opens, θ2 represents the rotation angle when the gripper 44 closes, and θ1 represents the weft insertion length according to the weaving width of the woven fabric, and the curve C The position indicated by A is the weft storage section 34.
This is when the drawing of the weft yarn is stopped by the first or second weft holding body 38° 39 on the top b. That is,
Weft insertion is completed by the locking action of both weft locking bodies 38 and 39.

In this embodiment, the yarn guide 46 is provided on the rotational axis of the nozzle pipe 33, so the weft Y attached and stored in the weft storage section 34b is pulled out in the same state, and the pulling resistance is constant. Therefore, weft tension fluctuations due to weft pull-out resistance are almost constant during weft insertion, and the weft insertion force ζ is stable.
Secured. Furthermore, since the weft yarn Y stored on the weft storage section 34b is simply attached to the surface of the moquette 36 forming the storage section 34b, the pull-out resistance itself is similar to the air boule method and drum boule method described above. It is very small compared to the length measuring device, and even when the injection pressure in the main nozzle 45 is reduced, weft insertion can be performed without any problem. Therefore, even a weft yarn with weak yarn strength can be inserted without causing a jetting failure in the main nozzle 35, and the amount of air consumption can be reduced.

Curve C1 shown in FIG. 14 shows the flying state of the weft yarn in the air boule type weft sub-length device obtained under the same injection pressure conditions as curve C, and curve C2 shows the flying state of the weft yarn in the air boule type weft sub-length device obtained under the same conditions as curve C. It shows the flying state of the weft in the weft storage device of the method, and each curve C, C1
, C2 shows that the weft pulling resistance during weft insertion is the lowest in the weft storage device 14 of the present invention.

Note that L represents the amount of weft fed out from the measuring roller nada structure in the conventional air boule type and drum boule type weft storage devices.

As described above, according to the weft storage device 14 of this embodiment, the length of the weft required for one weft insertion is accurately stored on the weft storage section 34b, and the length of the weft required for one weft insertion is accurately stored on the weft storage section 34b. The length of the weft yarn drawn out corresponds to one weft insertion.

By the way, the weft yarn is attached and stored in a coil shape on the weft yarn storage section 34b, and the form of this coiled storage depends on the moving speed of the spout 33a of the nozzle pipe 33. Therefore, in order to adjust the moving speed of the jet nozzle 33a in order to properly control the storage form, the jet nozzle 33a should be moved in the radial direction [i
! ! ! For example, if the nozzle pipe 33 is configured to be replaceable, as shown in FIG. Can be adjusted. In addition, when changing the weaving width of the woven fabric, it is necessary to change the length measurement amount by 6 by changing the rotation speed of the drive roller 15 in the length measurement roller row structure 13. The weft storage speed on the storage section 34b must also be changed. However, similarly to the above, changing the weaving width can be easily coped with simply by replacing the nozzle pipe 33 and changing the moving speed of the jet nozzle 33a. As a method of adjusting the position of the spout of the weft storage nozzle N in the radial direction, an embodiment similar to that shown in FIG. An abbreviated auxiliary pipe 48 is attached to the tip of the pipe 48 so that its sliding position can be adjusted, and the spout 48a of the pipe 48 is connected to the weft storage section 3.
4b so as to be oriented substantially perpendicular to 4b. Therefore, adjustment of the weft storage speed or adjustment of the weft storage m according to a change in the weaving width of the woven fabric can be made by simply sliding the auxiliary vibrator 48 in the radial direction of the weft storage body 38 based on tightening or loosening the screw 49. Extremely easy to operate.

The weft yarn Y attached and stored on the weft storage section 34b is attached to the weft yarn storage section 34b based on the operation of the electromagnetic solenoids 50 and 51 disposed on the front surface of the periphery of the weft storage section 34. Splash around 52.53.

It is locked by weft locking bodies 56 and 57 which are rotatably pressed onto the weft storage section 34b against rings 54 and 55. Then, the weft Y attached and stored on the weft storage section 34b is pulled out from the insertion hole 34a provided in the center of the weft storage section 34 in the direction of the yarn guide 46 arranged on the rotation axis of the nozzle pipe 33. It has become so. In this embodiment, the thread guide tube 5 is made of a highly wear-resistant material such as ceramic.
8 is fitted into the insertion hole 34a. According to this embodiment, it is possible to appropriately set the timing of weft locking by the weft locking bodies 56, 57. For example, just before the end of weft insertion, the electromagnetic solenoid 50.51 is actuated to control the weft locking bodies 56, 57.
It is also possible to press the weft yarn onto the weft storage section 34b, thereby stopping the weft withdrawal from the weft storage section 34b.

The weft locking by the locking bodies 56 and 57 may be released at an appropriate time before the start of the next weft insertion.

Accurately adhered and stored.

In the embodiment shown in FIG. 7, a weft storage body 65 is constructed by forming a weft storage portion 65a on the outer peripheral surface of the drum, contrary to the case shown in FIG. A cam plate 66 is attached to the nozzle pipe 33.
are fixed to the drum, and weft locking bodies 67 and 68 are rotatably supported on shafts 69 and 70 at the rear of the outer periphery of the drum.
is pressed against the cam surface by springs 71 and 72.

Note that both ends of the spring fin are latched to a pair of latching pins 73 (only one is shown in the drawing) that are latched to the rear end of the drum, and the center portion of the spring 71 is pulled by the weft latching body 67. The other weft locking body 68 and spring 72 have a similar relationship. In this embodiment as well, the weft Y that is attached and stored on the weft storage section 65a as the cam plate 66 rotates.

On 5a, the length of the weft for one weft insertion is accurately stored between the two weft locking bodies 6'7 and 68.

Then, the stored weft yarn with a length equivalent to one weft insertion is pulled out in the same state in the direction of the yarn guide 46 arranged on the rotation axis of the nozzle pipe 33, and stable weft insertion is performed.

In the embodiment shown in FIG. 8, a weft storage body 74 is constructed by forming a weft storage section 74a made of moquette at the front of the inner peripheral surface of the cylinder. The distal end side of the nozzle pipe 33 is bent in a right angle direction, and the spout 33a is connected to the weft storage section 74.8.
is oriented to. Further, a cam body 75 having a cam groove 75a on the cylindrical circumferential surface is fixed to the nozzle pipe 33, and a pair of guide grooves 74b facing each other is provided on the inner circumferential surface of the weft storage body 74. They are formed in the axial direction of the nozzle pipe 33, and weft locking bodies 76 and 77 are slidably blown into the guides *74b, respectively. Cam grooves 75a1. : The rotors 76a, 7 in the fitted state
7a is interposed, and rubber rollers 76b and 77b are rotatably attached to the tips of the weft locking bodies 76 and 77. Therefore, as the cam body 76 rotates, the weft locking bodies 76 and 77 alternately reciprocate in the direction of the rotational axis of the nozzle pipe 33, and the rubber rollers 76b and 77b move the weft Y that is attached and stored on the weft storage section 74a. This controls the storage of the weft for the length of one weft insertion and the withdrawal of the weft. The weft yarn Y adhered and stored on the annular weft storage portion 74a is transferred to the nozzle pipe 3.
The yarn is pulled out in the direction of the yarn guide 46 arranged on the rotation axis of No. 3, and stable weft insertion is performed.

In this embodiment, the nozzle pipe 33 rotates one-fourth of a rotation per one rotation of the machine, and the length of the weft for one weft insertion is stored between a pair of adjacent weft locking bodies. . Therefore, as in the case of the embodiment shown in FIG. If controlled appropriately using a magnetic solenoid, it is possible to store the weft yarn for three times of weft insertion. If two or three such devices are used, different weft yarns can be attached and stored in each storage device, making it easy to select multicolored weft yarns.

In this embodiment, the spout 33a of the nozzle pipe 33 is oriented in a direction oblique to the circumferential direction of the annular weft storage section 34b, and this direction is determined by the rotational speed of the nozzle pipe 33 and the spouting speed of the weft Y.
