Description

  The present invention relates to a weaving method and apparatus in a loom that performs warp opening movement using a depolarization opening device and performs weft insertion using water, air, rapier, or the like.

  A so-called positive opening device that moves the cocoon frame up and down only by a cam mechanism and performs warp opening movement, or a so-called depolarization opening device that drives the heel frame in one direction by a cam mechanism and drives it in the other direction by a spring to perform warp opening movement. In the weaving machine using, it is necessary to connect a new warp beam warp and an old warp on the woven fabric one by one when weaving. This warp tying operation is usually performed using an automatic machine such as a tying machine. In this case, it is necessary to perform weaving so that the warp yarns can be separated one by one reliably. In particular, in the water jet loom, there is no mechanism for guiding the warp from the warp feeding side to the reed frame, so that warp knitting at the time of warp joining work is poor, and weaving is more necessary.

  However, for twilling, for example, in the case of a woven fabric other than plain weave such as twill weave, even if the heel frame is simply moved up and down by the cam mechanism of the opening device, the warp cannot be opened up and down one by one like the plain weave. . For this reason, conventionally, the invention has been devised as in Patent Document 1 or Patent Document 2 below.

  In Patent Document 1, as shown in FIG. 1 and FIG. 8 shown in the same document, positive opening devices 2 and 31 (hereinafter referred to as Example 1) installed below the gutter frame 6 and FIG. As described above, the twilling device in the depolarization opening devices 2 and 32 (hereinafter referred to as Example 2) is disclosed. Each of these twilling devices has a mechanism including an engagement member 11 for specifically attaching the engagement pin 12 or the engagement piece 22 to the upper frame of the reed frame 6 and engaging the engagement pin 12 with the loom frame 16. Alternatively, a mechanism including the hook 36 or a mechanism including the engaging member 11 and the compression spring 21 is installed. When weaving, the cam mechanism of the positive opening device or the depolarization opening device is operated to move the heel frame 6 upward. For example, the engagement pin 12 or the engagement pin 12 of the heel frame 6 selected as an odd frame out of all the heel frames The piece 22 is engaged and held by the engaging member 11 or the hook 36. This operation is performed for one cycle of the woven fabric, and all the heel frames corresponding to the odd frames are held in the upper position. Next, the cam mechanism is operated a plurality of times until all the hook frames that hit the even frame are positioned on the lower side to create a warp opening state corresponding to a flat opening, and a traverse is performed by inserting a traversing bar there.

  Further, in the embodiment shown in FIG. 10 of Patent Document 1 (hereinafter referred to as Embodiment 3), the positive opening device 2 and 31 shown in FIG. And a cam lever are forcibly separated from each other and a so-called leveling device 34 for moving all the collar frames 6 in one direction is disclosed. In the third embodiment, instead of driving the positive opening device as in the first embodiment, all the hook frames 6 are moved upward by the leveling device 34, and one hook is attached to the engagement pin 12 of the odd frame at the upper movement position. The hook 36 is hooked, and the hook 30 connected to the one hook 36 by the wire 30 is hooked to the engaging pin 12 of the even frame, and the other hook 36 wound around the displacement member 25 is hooked. Thereafter, the displacement member 25 is rotated, for example, the selected odd-numbered frame is further pulled upward and held at that position. Although there is no specific description other than the above, in Example 3, since an opening is generated between the warp of the odd frame pulled up further than the leveling position and the warp of the even frame at the leveling position, the weave is performed. It is speculated that it can be done.

  In addition, it is described that the leveling device 34 described above may be combined with the depolarization opening devices 2 and 32 shown in the second embodiment after the middle stage of the upper left column on page 6 of Patent Document 1 (hereinafter referred to as implementation). Example 4). Example 4 is not specifically described and is unclear, but if interpreted as described in the specification, the leveling device 34 moves the entire frame to the same upper position, and then the frame not selected. Only the number 6 is used to release the pulling force by the leveling device, and the opening device 2 is inchingly operated so that the frame 6 is positioned in a direction opposite to the pulling direction of the leveling device. Therefore, in the case of the fourth embodiment, for example, the selected odd frame is maintained at the upper leveling position by the pulling force of the leveling device, and the other even frames are released from the leveling device and then leveled by driving the opening device 2. It is presumed that the yarn is moved to a predetermined position on the opposite side to the position, and a flat opening state of the warp is created by these operations, and the wefting is performed.

  Patent Document 2 includes an embodiment (hereinafter, referred to as Embodiment 1) in which the positive opening device shown in FIGS. 1 to 5 of the same document is provided with a leveling device and performs twilling, and the depolarization opening device shown in FIG. An example (hereinafter, referred to as Example 2) that performs leveling with a leveling device is disclosed.

  In Example 1 of Patent Document 2, the cam lever 7 in the cam box 12 is pulled away from the cam 10 to the leveling position L by the operation of the leveling device M1. In the leveling position L, there is arranged a stopper shaft 36 having five recesses 41 carved for every other cam lever shown in FIG. 5 and five recesses 42 shifted by one cam lever. One recess 41 is opposed to the cam lever 7. Accordingly, of the 10 cam levers, 5 cam levers come into contact with the large-diameter portion 40 of the stopper shaft 36 and are stopped at the leveling position L, and the remaining 5 cam levers are further pulled by the weight of the collar frame 1 or the like. Into the recess 41. As a result, an opening is formed between the warp of the cocoon frame connected to the cam lever regulated by the large diameter portion 40 and the warp of the cocoon frame connected to the cam lever in the recess 41, and the weaving is performed.

In Example 2 of Patent Document 2, a recess 56 similar to that of Example 1 of Patent Document 2 is formed on the stopper shaft 55 of the leveling device M2 that contacts the cam lever 7 of the depolarization opening device. The concave portion 56 is set so as to face the cam lever 7 during the weaving operation. Next, when the leveling device M2 is operated, first, the large-diameter portion 55a of the stopper shaft 55 comes into contact with half of the cam levers 7 and moves in a direction away from the cam 10. Subsequently, the stopper shaft 55 fits the remaining cam lever 7 into the recess 56, reaches the leveling position L, and stops. In this state, the cam lever 7 in contact with the large-diameter portion 55 a is at the leveling position L, and the cam lever 7 fitted in the recess 56 is at a position before the leveling position L by the depth of the recess 56. Accordingly, the warp yarns connected to the respective cam levers 7 are opened in the same manner as in the above embodiment, and the wefting is performed.
Japanese Patent Laid-Open No. 4-136229 Japanese Patent No. 3069596

  In Examples 1 and 2 of Patent Document 1 described above, in order to hold all the selected heel frames, for example, odd-numbered frames, at the upper position, the opening device is driven and the opening motion is performed by the number of times corresponding to one cycle of the woven fabric. Must be done. Moreover, it is necessary to perform the opening motion for positioning the remaining even number frames further several times. Therefore, there is a problem that the operation for the weaving is complicated and time-consuming, for example, a plurality of hooking operations are required for driving the opening device a plurality of times and holding the selected odd frame. Moreover, for example, some twill weave structures have a longer number of cycles, and thus the above problem has to be greater.

  The third embodiment of Patent Document 1 uses a leveling device as a positive opening device, and is a selected heel frame after all the heel frames are moved to a predetermined upper leveling position by the leveling device. The odd-numbered frame must be pulled further upward than the leveling position. Therefore, the leveling device is responsible for maintaining the even frame, which is the unselected frame, at the leveling position. For this reason, it is necessary to newly add a device for pulling up the selected gutter frame, and it is necessary to install a complicated device above the gutter frame. Further, the twilling operation has to perform a complicated frame moving operation using two different means, that is, upward movement of the entire frame by the leveling device and subsequent further movement of the selected frame.

  In Example 4 of Patent Document 1, a leveling device is used as a depolarization opening device. For example, a selected odd frame is held at a leveling position, and other even frames are released from the leveling position. In addition, the leveling device requires a structure that can individually act on a plurality of cam levers, and thus has a complicated structure. Further, in addition to the operation of the leveling device, it is also necessary to drive the depolarization opening device.

  In Examples 1 and 2 of Patent Document 2, although there is a difference between the positive opening device and the negative opening device, each of the cams has a stopper shaft provided with a recess facing the cam lever as a part of the leveling device. It is installed in a box. In Patent Document 2, it is necessary to adjust the position of the concave portion of the stopper shaft between the normal leveling operation and the twilling operation, which is very complicated. In particular, in Example 2 of Patent Document 2, since the weaving is performed in a leveled state, a large tension is generated in the warp, and the warp may be easily stretched or cut.

  In view of the above problems, an object of the present invention is to make it possible to easily perform weaving at the time of weaving or the like with a simple operation and apparatus.

  In the present invention represented by claim 1, the restriction member prevents the odd-numbered frame or the even-numbered frame from returning to the warp opening movement position from the leveling position due to the tension of the spring. This is a weaving method in which weaving is performed by forming a predetermined opening with the warp of the cocoon frame that has been prevented from returning to the warp opening movement position by the regulating member and the warp of the cocoon frame having returned to the warp opening movement position. .

  The invention of this application represented by claim 3 is provided with a restricting member that prevents return of either the odd frame or the even frame to the warp opening movement position when returning from the leveling position. Is a weaving apparatus for carrying out the weaving method described in 1).

  The invention of the present application solves the problems of the prior art. According to the invention of claim 1, it is possible to easily perform the chamfering work, and according to the invention of claim 3, the configuration for the chamfering can be simplified. Can be obtained.

(First embodiment)
Hereinafter, a first embodiment will be described with reference to FIGS.
FIG. 1 is a schematic view showing the arrangement relationship between a depolarization opening device 1, a leveling device 2, and a regulating member 3 according to the present invention.
A plurality of eaves frames 5 arranged between the left and right frames 4 and 4 of the loom (in this embodiment, as shown in FIGS. 5 and 6, the eaves frame 5a, 5b, 5c, 5d, 5e, and 5f are formed. ), The rope connection brackets 7 and 7 are fixed to the left and right side stays 6 and 6 by the mounting brackets 8 and 8 and integrated. Further, upper ropes 9 and 9 and lower ropes 10 and 10 are fixed to the rope connection brackets 7 and 7.

The depolarization opening device 1 is attached to the upper surfaces 15 and 15 of the left and right frames 4 and 4 and the cam lever 14 that rotates around the cam 12 and the shaft 13 in the cam box 11 installed near the outer floor surface of the right frame 4. It consists of springs 16 and 16. The cam lever 14 has a cam follower 14a that comes into contact with the cam 12, and is connected to lower ropes 10 and 10 that extend through guide rollers 17 and 17 disposed below the collar frame 5, and the springs 16 and 16 are respectively connected to a shaft 18. , 18 are connected to the upper ropes 9, 9 via jack levers 19, 19 that rotate about the center.
Therefore, as is well known, the eaves frame 5 is driven downward by the cam 12 and the cam lever 14 via the lower ropes 10, 10, and the jack levers 19, 19 and the upper ropes 9, 9 are driven by the tension of the springs 16, 16. And the warp opening movement is performed.

  The leveling device 2 is installed in the cam box 11 in a known form. As shown in FIGS. 2 and 3, the hydraulic cylinder 20 is installed on a bracket 21 fixed to the outer surface of the side wall of the cam box 11. The hydraulic cylinder 20 has a hose 22 connected to a hydraulic pump (not shown) and a piston rod 24 with a rack 23 attached to the tip. The rack 23 is placed on a guide 25 fixed to the outer surface of the side wall of the cam box 11 and is urged toward the hydraulic cylinder 20 by a spring 26.

On the other hand, in the cam box 11, a leveling lever 27, which is formed in a substantially U-shape when viewed from above and is long enough to cover all the cam levers 14, is rotatably attached to the shaft 13, and a fan-shaped gear is mounted on the rear surface thereof. 28 is provided.
A rotating shaft 29 parallel to the shaft 13 is further installed in the cam box 11. The rotary shaft 29 has a pinion 30 that meshes with the rack 23 at one end thereof, and a drive gear 31 that meshes with the sector gear 28 at the other end.

In a state where the leveling device 2 is not operated, the rack 23 is moved to the hydraulic cylinder 20 side by the biasing force of the spring 26, and the drive gear 31 rotates the sector gear 28 counterclockwise in FIG. It is held at a position where it does not come into contact with the cam lever 14.
When the leveling device 2 is operated, the rack 23 is moved in the protruding direction by supplying pressure oil to the hydraulic cylinder 20, and the sector gear 28 is rotated clockwise in FIG. 3 via the pinion 30 and the drive gear 31. To do. For this reason, the leveling lever 27 rotates all the cam levers 14 clockwise to pull the cam follower 14a away from the cam 12, and moves all the collar frames 5 to a leveling position below the normal opening position to align them. Can do.

  As shown in FIG. 4, the restricting member 3 is attached to an L-shaped bracket 32 fixed by bolts 33 on the upper surfaces 15, 15 of the left and right frames 4, 4. Since the restriction member 3 has the same structure on both the left and right sides, only what is provided on the upper surface 15 of the right frame 4 will be described below.

As shown in FIGS. 4 to 6, the restricting member 3 includes a U-shaped member composed of a mounting plate 34 and arm portions 35 and 36 protruding from both sides thereof, and bolts 37 and 38 on the lower surfaces of the arm portions 35 and 36. A main body is formed by the restriction bar 39 to be fixed.
The regulation bar 39 has long holes 40 and 41 for inserting bolts 37 and 38 formed at both ends thereof, and screw holes 42, 43, 44 and 45 formed in an intermediate portion. The screw holes 42, 43, 44, 45 are arranged every other frame, and in FIG. 5, correspond to the frame 5 c, 5 e that is an odd frame with the frame 5 a located closest to the weaving side as a base point. is doing. When the screw holes 42, 43, 44, 45 are made to correspond to the collar frames 5b, 5d, 5f, which are even frames, the bolts 37, 38 are loosened, and the restriction bar 39 in FIG. The bolts 37 and 38 may be fastened and fixed by moving to the left side. In addition, although the screw hole 45 is a reserve and has shown the example of 6 rib frames in this embodiment, it is comprised so that it can respond also to 8 rib frames with the same control member 3. Therefore, it is also possible to form screw holes so as to correspond to the maximum number of collar frames expected to be used.

  In the screw holes 42, 43, 44, 45 of the restriction bar 39, restriction rods 46, 47, 48, 49 as restriction parts are mounted, respectively. Each regulation rod 46, 47, 48, 49 has a male screw engraved on a part or all of it, and is attached to each screw hole 42, 43, 44, 45 by screwing, and nuts 50, 51, 52, 53 is fixed. The regulating rods 46, 47, 48 mounted in the screw holes 42, 43, 44 can come into contact with the upper surfaces 6a of the side stays 6 of the corresponding collar frames 5a, 5c, 5e, respectively. Moreover, the height position of each control rod 46, 47, 48, 49 can be adjusted by the degree of screwing.

  In FIG. 5, the restriction rod 46 corresponding to the collar frame 5a closest to the front side of the weave is set to the highest position, and the positions of the regulation rods 47 and 48 corresponding to the collar frames 5c and 5e far from the front side of the weave are sequentially lowered. Is set to As shown in FIG. 7 (b), the warp Wa of the heel frame 5a is set as a reference position of the opening amount necessary for weaving, and the other warps Wc and We are on the same plane as the reference position or outward from it. Done to position. Although the warp Wc or We may be used as the reference position, there is a possibility that the height adjustment of the regulation rods 46, 47, 48 may be slightly difficult as compared with the warp Wa.

The restricting member 3 is installed by fixing the mounting plate 34 to the L-shaped bracket 32 with bolts 54 and 54. During the weaving operation of the loom, the regulation rods 46, 47, 48 are fixed at the highest position so that they do not come into contact with the side stays 6 of the frame frames 5a, 5b, 5c, 5d, 5e, 5f.
Since the regulating member 3 is not used during the weaving operation, it can be removed and used as a tool to be attached to the loom only during the weaving. In this way, an operation for attaching the regulating member 3 is required, but the number of regulating members 3 can be small.

The operation of the first embodiment configured as described above will be described below.
For example, when the weaving operation is completed and the warp beam is exchanged for the specification change, old and new warp joining is required as the weaving operation.
When the operator first operates the leveling device 2, the pressure oil is supplied to the hydraulic cylinder 20 so that the rack 23 protrudes upward in FIG. 2, and the pinion 30, the rotating shaft 29, and the drive gear 31 are counterclockwise in FIG. 3. To turn. For this reason, the leveling lever 27 rotates in the clockwise direction in FIG. 3 via the sector gear 28 that meshes with the drive gear 31, and all the cam levers 14 are resisted against the tensile force of the spring 16 of the depolarization opening device 1. Rotate to position.

  As a result, the cam follower 14 a reaches the imaginary line position outside the rotation locus circle 12 a of the large diameter portion of the cam 12 and is not affected by the cam 12. Accordingly, the flange frames 5a, 5b, 5c, 5d, 5e, and 5f connected to the cam lever 14 are moved and aligned to a leveling position below the normal opening movement position, as shown in FIG. The warps Wa, Wb, Wc, Wd, We, Wf are arranged at substantially the same surface position.

  Next, the operator sets the regulating member 3 at a position corresponding to the eaves frame selected as an object of restriction, here, eaves frames 5a, 5c, and 5e that are odd frames counted from the front side of the weave. First, it is confirmed that the restriction bar 39 is positioned on the right side of FIG. 5 and that the restriction rods 46, 47, 48 correspond to the collar frames 5a, 5c, 5e. Next, the nut 50 is loosened, the restriction rod 46 is screwed in and set to the height of the reference position, and the nut 50 is fixed by tightening. Similarly, the restriction rods 47 and 48 are set at positions sequentially lower than the restriction rod 46 and fixed. The heights of the restriction rods 46, 47, 48 are set so that the cam followers 14 a corresponding to the collar frames 5 a, 5 c, 5 e come into contact with the rotation locus circle 12 a of the large diameter portion of the cam 12 before the restriction rod 46. , 47 and 48 are set at positions where they contact the side stays 6 of the collar frames 5a, 5c and 5e.

  Subsequently, the operation of the leveling device 2 is stopped, and the movement of all the collar frames 5a, 5b, 5c, 5d, 5e, and 5f is released. That is, when the supply of pressure oil to the hydraulic cylinder 20 is stopped, the rack 23 returns to the lower side in FIG. 2 due to the tensile force of the spring 26, so that the drive gear 31 and the sector gear 28 rotate in the direction opposite to that during the leveling operation. The leveling lever 27 moves away from the cam lever 14 and returns to the solid line position in FIG.

At the same time, all the collar frames 5a, 5b, 5c, 5d, 5e, and 5f are moved back upward, that is, toward the warp opening movement position side by the tensile force of the spring 16 of the depolarization opening device 1. During this return movement, the upper surfaces 6a of the side stays 6 of the saddle frames 5a, 5c, 5e, which are in contact with the selected odd-numbered frames, abut against the restricting rods 46, 47, 48, respectively, preventing further return movement. (See FIG. 7B).
Since the rods 5b, 5d, and 5f corresponding to the even-numbered frames that have not been selected have no restriction rod, they completely return upward to the position where the corresponding cam follower 14a contacts the cam 12 (warp opening movement position) (FIG. 7B). )reference).

In the odd frame in which the return movement is prevented, the warps Wc and We of the other heel frames 5c and 5e are substantially on the same plane as the reference position with the warp Wa of the heel frame 5a as a reference position, An opening having a predetermined height is formed between the warp frame 5b at the lowest position and the warp Wb.
Therefore, the weaving is performed by inserting a weaving bar (not shown) in the space between the warp Wa and the warp Wb.

  Next, the leveling device 2 is operated again to move all the collar frames 5a, 5b, 5c, 5d, 5e, and 5f to the leveling positions in FIG. In this state, the operator selects the eaves frames 5b, 5d, and 5f that are even frames as the object of restriction, and sets the restriction member 3 at the corresponding position. That is, the bolts 37 and 38 of the restricting member 3 are loosened, and the restricting bar 39 is moved to the left in FIG. 5 by the length of the long holes 40 and 41. At this position, the restriction rods 46 to 48 correspond to the flange frames 5b, 5d, and 5f, respectively, so that the bolts 37 and 38 are tightened and the restriction bar 39 is fixed to the arm portions 35 and 36.

Since the height of each of the regulating rods 46 to 48 is adjusted with the regulating rod 46 as a reference position when the odd-numbered frame is selected, no particular adjustment is required.
However, since there is a slight shift in the longitudinal direction of the loom between the hook frames 5a and 5b, the height positions of the restriction rods 46 to 48 should be readjusted if the restriction position of the hook frame 5b is not allowed as the reference position. That's fine.

  When the operation of the leveling device 2 is stopped after the setting of the regulating member 3 is completed, the movement of all the collar frames 5a to 5f to the leveling position is released, and the tensile force of the spring 16 of the depolarization opening device 1 is the same as in the above-described traversing. The return movement to the warp opening movement position is started. However, as shown in FIG. 7C, the selected saddle frames 5b, 5d, and 5f are prevented from returning in the middle by the restriction rods 46, 47, and 48, and the selected saddle frames 5a, 5c, 5e completely returns to the position where the cam follower 14a contacts the corresponding cam 12.

Accordingly, the warp yarns Wa, Wc, We and the warp yarns Wb, Wd, Wf are arranged in the reverse direction up and down from the time of the weaving by going around a weaving bar (not shown) inserted at the time of the weaving. In addition, since an opening having a predetermined height is formed between the warp Wb serving as the reference position and the lowermost collar frame Wa among the odd-numbered frames that have been completely restored, the second twill bar (see FIG. (Not shown) can be inserted and twilled.
Usually, the weaving is performed using two weaving bars, but if necessary, the operations shown in FIGS. 7B and 7C are alternately performed a plurality of times to insert a plurality of weaving bars. This can be done in a short time with a simple operation.
Further, the height adjustment of the restriction rods 46 to 48 when setting the restriction member 3 may be performed once at the first rounding, and at the subsequent rounding, the restriction bar 39 is alternately turned to the left and right in FIG. Therefore, the setting operation can be performed very efficiently.

  After the above-described weaving operation is completed, the leveling device 2 is actuated again, and all the collar frames 5a to 5f are moved to the leveling position in FIG. By this operation, the restriction rods 46 to 48 are released from the contact state with the selected odd-numbered frame or even-numbered side stay 6, so that the restriction rods 46 to 48 are moved more than the opening movement position of the eaves frame during weaving. Displace to the upper position and fix. Thereafter, by stopping the operation of the leveling device 2, all the collar frames 5a to 5f are completely restored, and all the operations necessary for the weaving are completed.

The above-described first embodiment of the present invention has the following effects.
(1) Using the return movement of the heel frame to the warp opening movement position by canceling the existing leveling operation, and only preventing the return movement of the selected heel frame, it is not necessary to operate another drive device. A flat opening for the weaving can be formed with a simple configuration and easy operation. Further, since the warps Wa, Wb, Wc, Wd, We, Wf are returned from the leveling position to the vicinity of the warp opening movement position, a large tension does not act on the warp during the weaving operation.
(2) The return movement prevention position of the selected heel frame is set as a reference position by setting the heel frame closest to the weaving side as a reference position, and by positioning the other heel frame at the reference position or outward from it, An opening having a required predetermined height can be reliably formed.
(3) Since the restraining member is brought into contact with the side stay of the saddle frame in order to prevent the return movement of the saddle frame, compared to the technique disclosed in Patent Document 1, no load is directly applied to the saddle frame. Does not affect the damage or lifetime. Further, the position of the side stay is open to the outside, and it is easy to perform the setting operation of the regulating member.

(4) The number of restriction rods is half that of the entire frame, and the restriction bar to which the restriction rod is attached can be moved in the front-rear direction of the loom, simplifying the structure of the restriction member and supporting the selected frame. It is easy to perform the setting operation.
(5) Since the attachment structure of the restriction rod to the restriction bar is screwed, the height adjustment of the saddle frame blocking position can be performed easily and accurately.
(Second Embodiment)

In the second embodiment shown in FIG. 8, the configurations of the regulation bar 39 and the regulation rods 46 to 49 of the regulation member 3 of the first embodiment are changed, and the other configurations are not changed.
The restricting bar 56 of the restricting member 55 is formed by a bar longer than the length of the entire hook frame used in the front-rear direction of the loom, and has long holes 57 and 58 at both ends thereof. The arm portions 35 and 36 shown in FIG. It can be fixed by bolts 37 and 38. On the lower surface of the restriction bar 56, four restriction rods 59, 60, 61, and 62 are integrally formed as four restriction portions protruding downward. The interval between the regulating rods 59, 60, 61, 62 is the width obtained by removing one frame. In addition, the restriction rod 59 corresponds to the collar frame closest to the weaving side among the selected collar frames when setting the regulation member 55, and this is used as a reference position for the other regulation rods 60, 61, 62. Projection length is set.

The twilling operation using the second embodiment can be carried out in the same manner as in the first embodiment, but the lengths of the regulating rods 59, 60, 61, 62 are determined in advance. The height adjustment operation for determining the return movement prevention position of the collar frame selected when the regulating member 55 is set is unnecessary, and the weaving operation can be further simplified.
When the restriction member 55 according to the second embodiment is always attached to the loom, the restriction member 59 is fixed to the arm portions 35 and 36 in FIG. 5 with the restriction rods 59, 60, 61 and 62 facing upward. There is no interference with the eaves frame that opens during production.

  The present invention is not limited to the configuration of each embodiment described above, and various modifications are possible within the scope of the gist of the invention, and can be implemented as follows.

(1) In the first embodiment, when the restricting member is not in use, the restricting bar may be fixed to the arm portion with the restricting rod facing upward as in the second embodiment. If it does in this way, once the height adjustment of a control rod will be performed, the subsequent adjustment will become unnecessary and it will be easy to carry out a weave operation.
(2) The restriction rod is pivotally mounted with the restriction bar as a support shaft, and is suspended and fixed when in use, and is rotationally displaced to a position where it does not interfere with the opening frame when not in use. It is good.
In addition, the control rods that can be pivotally mounted are arranged as many as the number of collar frames to be used, and when used, only the regulation rod corresponding to the selected collar frame is fixed in a suspended state, and the other regulation rods are inverted and selected. It is also possible to adopt a configuration in which it is rotationally displaced to a position that does not contact the collar frame that has not been provided. In this example, when the regulating member is not used, all the regulating rods may be rotationally displaced to a position where they do not interfere with the eaves frame that performs the opening movement.

  (3) The restricting rod of the restricting member is provided so as to be movable in the horizontal direction with an inclined surface formed at the tip, like the engaging member 11 shown in FIG. When setting, the horizontal movement amount of the restriction rod corresponding to the collar frame closest to the weaving side is minimized, and the horizontal movement amount of other restriction rods is sequentially increased to set the return movement prevention position of the collar frame. May be. In the case of this example, if a slope portion corresponding to the slope of the regulating rod is formed on the side stay side of the collar frame, both can be brought into contact with each other by surface contact.

  (4) The restriction member may be configured to directly contact the upper frame or the lower frame of the collar frame.

(5) The restricting member may be configured to come into contact with a part of the rope connecting bracket fixed to the frame or other integrated member.
(6) In the first embodiment, the same number as the number of all the frames using the regulating rods of the regulating members may be used, and the arrangement may be made with the same pitch as the frame.
