In a loom equipped with a warp delivery device, when the warp handling is poor due to the opening operation of the warp during weaving, the position of the easing roll in the vertical direction can be adjusted to improve the warp handling. It is commonly done. Then, in a general loom, for example, a configuration for adjusting the position (position adjustment) of the easing roll in the vertical direction as disclosed in Patent Document 2 is adopted. Therefore, although such position adjustment is not particularly disclosed in Patent Document 1, it is disclosed in Patent Document 2 so that the position adjustment is possible even in the warp sending device of Patent Document 1. The configuration is considered to be adopted.

Incidentally, regarding the configuration for the position adjustment disclosed in Patent Document 2, the warp feeding device of Patent Document 2 is inserted into a support structure (bracket referred to in Patent Document 2) that supports the easing roll. The support structure is attached to the loom frame by screwing the bolt into the loom frame. On top of that, as a configuration for adjusting the position, the hole through which the bolt is inserted in the support structure is formed as an elongated hole extending in the vertical direction. That is, the mounting configuration of the support structure to the loom frame is such that the position of the support structure supporting the easing roll in the vertical direction can be changed within the range of the elongated hole so as to enable the position adjustment of the easing roll. It has become. Further, the warp feeding device includes a position adjusting mechanism including a jack bolt for adjusting the vertical position of the support structure as a configuration for the position adjustment.

By the way, as described above, the warp sending device of Patent Document 1 is provided with an easing mechanism (easing roll) corresponding to each of the two warp beams, and each easing roll is provided corresponding to the support. It is configured to be supported by the loom frame by the structure. In that case, when the position adjustment is performed in the warp delivery device in order to improve the handling of the warp as described above, the position of the corresponding support structure in the vertical direction is adjusted for each of the easing rolls. Work must be done.

More specifically, since the handling of the warp threads is related to the type of the warp threads and the like, it is considered that the position adjustment is performed independently for each warp thread beam (in some cases, one of them is not adjusted). However, the distance between the first easing roll and the second easing roll in the vertical direction in the warp sending device as described above is determined in relation to other weaving elements in consideration of the type of warp and the like. It is set to be done properly. Therefore, the position adjustment work is performed so that the interval is the same even after the adjustment. That is, in the position adjustment work, the position of one of the first easing roll and the second easing roll (the support structure that supports the one easing roll) is adjusted, and then the position is adjusted. The position of the other easing roll (the support structure that supports the other easing roll) is adjusted so that the interval is the same as that of the easing roll of one of the easing rolls before the position adjustment.

As described above, in the warp sending device of Patent Document 1, the position adjusting work for improving the handling of the warp as described above is performed for each of the two support structures each supporting the easing roll. It is necessary to adjust the position in the vertical direction. Therefore, the work requires a lot of time and labor as compared with a general loom having one warp beam, and puts a heavy burden on the operator.

Therefore, in view of the above problems, it is an object of the present invention to provide a configuration capable of reducing the burden on the operator when adjusting the position of the easing roll in the warp sending device presupposed as described above. To do.

The present invention is a single support structure that is displaceably attached to the loom frame in the vertical direction in the warp delivery device that is premised on the above in order to achieve the above object, and is separated in the weaving width direction. A pair of support structures are provided, and the support structure is the first support portion for supporting the support shaft in the easing mechanism of one of the two easing mechanisms and the support structure in the other easing mechanism. It is characterized by having a second support portion for supporting the support shaft.

The "single support structure" referred to in the present invention is integrally formed as a single structure including the first support portion and the second support portion described above, and is integrally formed at one place in the loom frame. Refers to a support structure that is attached to the loom frame at the attachment position. Therefore, two support structures each of which is formed to have a support portion (first support portion, second support portion) and each of which is attached to the loom frame at a different attachment position. The combination of structures is not included in the "single support structure". Further, the "integral formation" referred to here includes, of course, the case of integrally molding by casting, processing, or the like, but is not limited to this, and also includes the case of combining and integrating a plurality of members.

Further, in the present invention, the support structure may be configured such that the first support portion and the second support portion are relatively displaceable in the vertical direction.

As described above, the warp delivery device according to the present invention and the warp delivery device including two warp beams is a pair of support structures in which each support structure is a single structure, and each support structure is provided. By a pair of support structures in which the body comprises a first support for supporting the support shaft of one easing mechanism in the two easing mechanisms and a second support for supporting the support shaft of the other easing mechanism. , Both support shafts in the two easing mechanisms are configured to be supported. That is, in the warp delivery device, the two support shafts and the first and second easing rolls supported by both support shafts are a pair of support structures, and the support structure common to both support shafts is used. It is configured to be supported.

Therefore, according to such a warp sending device according to the present invention, by adjusting the position of the common support structure in the vertical direction, the positions of the first and second easing rolls can be adjusted at the same time. It will be done. Moreover, the position of the support structure in the vertical direction is adjusted while maintaining the distance between the two easing rolls. As described above, according to the warp delivery device, the position adjustment of the two easing rolls, which are required to have the same interval before and after the position adjustment work, is the position in the vertical direction of the common support structure. Since it can be realized only by adjusting the above, the burden on the operator is reduced as compared with the conventional device.

Further, in the warp sending device according to the present invention, when the first support portion and the second support portion in the support structure are configured to be relatively displaceable in the vertical direction, the interval is set as the type of warp. It is possible to adjust it to an appropriate one according to the above.

The lower beam guide 14a is provided in each lower delivery frame 13a so as to be attached to the inner side surface of the lower delivery frame 13a. Further, each lower beam guide 14a is lowered at a position such that the axial center (rotation center) of the lower warp beam 21 that supports the lower beam guide 14a is near the rear end surface of the rear portion 12b of the main body frame 12 in the front-rear direction. It is provided on the side delivery frame 13a. Therefore, the lower warp beam 21 is supported by both lower delivery frames 13a and 13a via the lower beam guides 14a and 14a between the pair of lower delivery frames 13a and 13a.

Each upper delivery frame 13b is provided so as to be mounted on the upper surface of the rear side portion 12b of the main body frame 12, and is connected to the rear side portion 12b on the lower surface thereof.

Is formed to have. As a result, the lower warp beam 21 and the upper warp beam 22 are arranged apart from each other in the vertical direction (at different positions) in a state of being supported by the pair of delivery frames 13 and 13.

Incidentally, in the state shown in FIG. 1, the lower warp beam 21 and the upper warp beam 22 are supported by a pair of delivery frames 13 and 13 so that their arrangements are slightly different even in the front-rear direction. However, since the difference in arrangement in the front-rear direction is very small as compared with the difference in arrangement in the vertical direction, the loom presupposed by the present invention is described in this embodiment as the lower warp beam 21 and the upper warp beam 22. Will be described as an example of a warp delivery device comprising two warp beams arranged at different positions in the vertical direction, that is, at different positions in the vertical direction.

In the loom 1 in which the two warp beams 21 and 22 are supported by the loom frame 10 (a pair of delivery frames 13 and 13) configured as described above, the warp delivery device 20 uses the two warp beams 21. It is provided with two easing mechanisms provided corresponding to each of the 22. That is, the warp delivery device 20 includes a lower easing mechanism 30a corresponding to the lower warp beam 21 and an upper easing mechanism 30b corresponding to the upper warp beam 22. In this embodiment, the easing mechanisms 30a and 30b are so-called passive easing mechanisms that alleviate tension fluctuations associated with the opening movement of the warp by the urging force of the easing spring. The details of the easing mechanisms 30a and 30b are as follows.

Usually, an easing mechanism in a loom includes a support shaft rotatably supported with respect to the loom frame, and the easing roll is supported at both ends by a pair of support arms attached to the support shaft. The roll is configured to be swingably supported with respect to the loom frame. Further, a general passive easing mechanism includes an easing portion connected to a support shaft, and the easing portion includes an easing spring that receives tension of the warp threads applied to the easing roll.

In a general loom in which weaving is performed by a warp drawn from a single warp beam, the warp sending device is a guide roll for guiding the warp drawn from the warp beam toward an easing roll. It has. Further, the guide roll is supported by the loom frame at its shaft portion by a bracket or the like attached to the loom frame. Further, also in this embodiment, in the loom 1, the warp delivery device 20 is a guide roll (hereinafter, also referred to as “lower guide roll”) 40a for guiding the warp drawn from the lower warp beam 21 and below the guide roll 40a. A support bracket 50 for supporting the side guide roll 40a is included, and the lower guide roll 40a is supported by the pair of support brackets 50, 50 on the loom frame 10.

More specifically, the support bracket 50 is attached to each main body frame 12 (rear side portion 12b) of the loom frame 10 so as to extend rearward with respect to the rear end surface. Each of the support brackets 50 has a base portion 51 attached to the rear side portion 12b and a shaft support portion 52 that supports the lower guide roll 40a behind the base portion 51, and is configured by integrally molding them. .. Further, the lower guide roll 40a is a pair of shafts provided integrally with the cylindrical guide portion 40a1 which is a portion around which the warp yarn is wound and the guide portion 40a1 so as to project from both ends of the guide portion 40a1. It is composed of parts 40a2 and 40a2. The lower guide roll 40a can rotate with respect to the pair of main body frames 12 and 12 in the loom frame 10 by supporting each of the shaft portions 40a2 by the shaft support portion 52 of each support bracket 50 via a bearing or the like. Is supported by. Further, in such a supported state, the axis of the lower guide roll 40a is parallel to the weaving width direction.

Further, as described above, each support bracket 50 that supports the lower guide roll 40a can adjust the mounting position with respect to the main body frame 12 in the vertical direction. Specifically, each support bracket 50 is attached to the main body frame 12 as described above by screwing a bolt 55 inserted into a mounting hole formed in the base portion 51 into the main body frame 12. .. Two mounting holes are formed so as to be arranged in the vertical direction. Each of the mounting holes is formed as an elongated hole extending in the vertical direction when the support bracket 50 is mounted on the main body frame 12. Therefore, the mounting position of the support bracket 50 with respect to the main body frame 12 in the vertical direction can be changed within the range of the elongated hole.

On top of that, the warp delivery device 20 includes a position adjusting mechanism 100 for changing the mounting position of each support bracket 50 with respect to the main body frame 12. Each position adjusting mechanism 100 has a fixing portion 101 attached to a rear end surface of the main body frame 12 (rear side portion 12b). Further, the fixing portion 101 is arranged at a position below the support bracket 50. Further, the fixing portion 101 has a female screw hole formed so as to penetrate in the vertical direction in the attached state.

Further, each position adjusting mechanism 100 has a jack bolt 102 screwed into the female screw hole of the fixing portion 101. Further, each position adjusting mechanism 100 is a receiving portion 103 provided on the support bracket 50, and has a receiving portion 103 provided so as to face the jack bolt 102 screwed into the fixing portion 101 in the vertical direction. doing. Therefore, in each position adjusting mechanism 100, the jack bolt 102 and the receiving portion 103 are in a state where they can come into contact with each other.

Regarding the operation of the position adjusting mechanism 100, in adjusting the position of the support bracket 50, first, the bolt 55 that attaches (fixes) the support bracket 50 to the main body frame 12 is loosened. As a result, the support bracket 50 is in a state of being displaceable in the vertical direction with respect to the main body frame 12 because the mounting holes are elongated holes as described above. Further, in that state, the end surface of the jack bolt 102 in the position adjusting mechanism 100 comes into contact with the lower surface of the receiving portion 103, that is, the support bracket 50 is supported by the jack bolt 102. Then, by changing the screwing amount of the jack bolt 102 with respect to the fixing portion 101 in the position adjusting mechanism 100, the position of the support bracket 50 is changed (adjusted) in the vertical direction according to the screwing amount. Then, at the changed position, the position of the support bracket 50 with respect to the main body frame 12 is fixed by the bolt 55, so that the position of the support bracket 50 in the vertical direction is adjusted.

Then, in such a warp delivery device 20, the lower easing mechanism 30a includes a pair of support arms 32, 32 for supporting the first easing roll 33, which is the easing roll in the lower easing mechanism 30a. ing. The pair of support arms 32, 32 are attached so as not to rotate relative to both shaft portions 40a2, 40a2 in the lower guide roll 40a. Therefore, the pair of support arms 32, 32 are swingably supported with respect to the loom frame 10 by the shaft portions 40a2, 40a2 of the lower guide roll 40a.

Further, the first easing roll 33 is swingably supported at both ends thereof with respect to the shaft portions 40a2 and 40a2 of the lower guide roll 40a via a pair of support arms 32 and 32, and is supported by the loom. It is provided so as to be swingable with respect to the frame 10. However, the first easing roll 33 is located above the lower guide roll 40a in the vertical direction in such a supported state.

Both shaft portions 40a2 and 40a2 of the lower guide roll 40a are connected by the guide portion 40a1 and integrated via the guide portion 40a1. That is, the guide portion 40a1 in the lower guide roll 40a is a member provided for guiding the warp threads, but also functions as a part of a shaft that supports the first easing roll 33. Therefore, the lower guide roll 40a including the guide portions 40a1 that function as a part of the shaft by connecting the shaft portions 40a2, 40a2 and the shaft portions 40a2, 40a2 to which the pair of support arms 32, 32 is attached is It can be regarded as the first support shaft 31 for supporting the first easing roll 33 in the lower easing mechanism 30a. In other words, the warp delivery device 20 of the present embodiment is configured such that the lower guide roll 40a is also used as the first support shaft 31 in the lower easing mechanism 30a.

Therefore, the lower easing mechanism 30a is configured with respect to the loom frame 10 via a support bracket 50 in which a first support shaft 31 for supporting the first easing roll 33 is attached to each main body frame 12. It has become a form of support. Further, as described above, since the lower guide roll 40a is provided in a state where its axis is parallel to the weaving width direction, the first support shaft 31 has its axis in the weaving width in the supporting state. It can be said that it is provided in the direction.

Incidentally, as a guide roll in a loom, there is a guide roll configured so that the guide portion is supported by a through shaft provided so as to penetrate the guide portion via a bearing or the like, and the lower guide roll 40a is the lower guide roll 40a. It may be configured as follows. When the guide roll thus configured is used as the lower guide roll 40a in the present embodiment, the through shaft in the guide roll functions as the first support shaft 31 instead of the entire guide roll. Will be (also used).

Further, in the warp delivery device 20, the lower guide roll 40a extends to the outside in the weaving width direction from the support bracket 50 in which one of the pair of shaft portions 40a2 and 40a2 supports the other shaft portion 40a2. It is configured as follows. That is, the first support shaft 31 in the lower easing mechanism 30a is provided so that one end side thereof extends to the outside of the support bracket 50 that supports itself. On top of that, the lower easing mechanism 30a includes an easing portion 60 connected to one end of the first support shaft 31 on the outside of the support bracket 50.

The easing portion 60 is attached to one end of the first support shaft 31 so as not to be relatively rotatable at one end thereof, and is provided so as to extend downward, and the loom frame 10 (main body) at one end thereof. It includes an easing rod 62 that is rotatably supported with respect to the frame 12) and extends rearward from the support position and is connected to the other end of the easing lever 61 at the other end. However, the easing lever 61 and the easing rod 62 are connected so that the connecting position of both can be displaced on the axis of the easing rod 62. Further, the easing portion 60 includes an easing spring 63, and the easing spring 63 is configured to be interposed between the easing lever 61 and the easing rod 62.

With this configuration, the easing unit 60 urges the first easing roll 33 in the swing direction by the easing spring 63 in order to apply a predetermined tension to the warp, and the easing roll 60 is accompanied by a change in the tension of the warp. The swing of 33 is received by the easing spring 63, and the tension fluctuation of the warp yarn can be alleviated.

Further, regarding the upper easing mechanism 30b, the upper easing mechanism 30b is rotatably supported with respect to the loom frame 10 with respect to the second support shaft 34 and the second support shaft 34, similarly to the lower easing mechanism 30a. It includes a pair of support arms 35, 35 that are attached so as not to rotate relative to each other, and an easing roll (second easing roll) 36 that is supported by the pair of support arms 35, 35 at both ends thereof. Therefore, the second easing roll 36 is swingably supported by the second support shaft 34 via the pair of support arms 35, 35. The second support shaft 34 in the upper easing mechanism 30b supports the second easing roll 36, unlike the first support shaft 31 in the lower easing mechanism 30a which also serves as a part of the lower guide roll 40a. It is provided as a dedicated shaft for.

The easing spring 83 receives the swing of the 36, and has an effect of alleviating the tension fluctuation of the warp.

Further, the warp sending device 20 includes a guide roll (hereinafter, “upper guide roll”) 40b provided corresponding to the upper warp beam 22. The upper guide roll 40b is rotatably supported by the loom frame 10 via bearings and the like. However, the upper guide roll 40b is located above the second easing roll 36 and below the upper warp beam 22 in the vertical direction while being supported by the loom frame 10 in this way. Then, the upper guide roll 40b guides the warp drawn from the upper warp beam 22 toward the second easing roll 36 in the upper easing mechanism 30b.

Incidentally, with respect to the support structure configured as such, the support bracket 50 is composed of a shaft support portion 52 and a base portion 51, and is attached to the loom frame 10 at the base portion 51. Therefore, the support structure is considered to be configured such that the first support portion (shaft support portion) 52 is supported by the loom frame 10 by the base portion 51 with respect to the configuration for supporting the first support shaft 31. be able to. On the other hand, as described above, the support metal 70 that supports the second support shaft 34 is attached to the base portion 51 of the support bracket 50. Therefore, the support structure is considered to be configured such that the second support portion (support metal) 70 is supported by the loom frame 10 by the base portion 51 with respect to the configuration for supporting the second support shaft 34. be able to. From these things, the support structure has a first support part 52, a second support part 70, and a common base part 51 which supports each support part, and each support part has a loom frame 10 by the base part 51. Can be considered to be configured to be supported by.

It is possible. Therefore, the support structure of the present embodiment, which is considered to be configured such that the first support portion 52 and the second support portion 70 are supported by the base 51 with respect to the loom frame 10 as described above, is a loom. It can be displaced in the vertical direction with respect to the frame 10.

The operation of the warp sending device 20 of the present embodiment configured as described above is as follows.

First, in the warp delivery device 20, in the vertical direction of the first easing roll 33 and the second easing roll 36, for the purpose of eliminating the poor handling of the warp due to the opening operation of the warp during weaving. Work may be done to adjust the position. Then, in the work, the adjustment of the positions of the first easing roll 33 and the second easing roll 36 in the vertical direction is performed by adjusting the positions of the first easing roll 33 and the second easing roll 36 in the vertical direction. This is done by adjusting the vertical position of 34.

Then, in the warp sending device 20, the position of the support bracket 50 in the vertical direction is adjusted by using the position adjusting mechanism 100 as described above. That is, the mounting position of the base 51 of the support bracket 50 with respect to the loom frame 10 is adjusted in the vertical direction. As a result, the support structure composed of the base 51 and the first support 52 and the second support 70 supported by the base 51 as described above is the first support 52 and the second support. As the support portion 70 of the above is integrated with the base portion 51, the position in the vertical direction is adjusted while maintaining the positional relationship between the two support portions. As a result, the positions of the support shafts 31, 34, and the easing rolls 33, 36 supported by the support portions are adjusted in the vertical direction while maintaining the positional relationship.

As described above, according to the warp delivery device 20, the vertical position adjustment of the two easing rolls 33 and 36, which are required to maintain the positional relationship before and after the position adjustment, is performed on both easing rolls. Since it can be realized only by adjusting the mounting position of the support structure supporting 33, 36 (first and second support shafts 31, 34) with respect to the loom frame 10 in the vertical direction, the position adjustment can be easily performed.

In this embodiment, regarding the attachment of each support metal 70 to the support bracket 50, the attachment holes for attachment in each support metal 70 are formed as elongated holes extending in the vertical direction in the attached state. .. Therefore, each support metal 70 can change its mounting position with respect to the support bracket 50 in the vertical direction within the range of its elongated hole.

Therefore, in each interval adjusting mechanism 110, the jack bolt 112 and the receiving portion 113 are in a state where they can come into contact with each other.

Regarding the action of the interval adjusting mechanism 110, in adjusting the position of the support metal 70, first, the bolt 75 that attaches the support metal 70 to the support bracket 50 is loosened. As a result, the support metal 70 is in a state of being displaceable in the vertical direction with respect to the support bracket 50 because the mounting holes are elongated holes as described above. Further, in that state, the end surface of the jack bolt 112 in the interval adjusting mechanism 110 comes into contact with the lower surface of the receiving portion 113, that is, the support metal 70 is supported by the jack bolt 112. Then, by changing the screwing amount of the jack bolt 112 with respect to the fixing portion 111 in the spacing adjusting mechanism 110, the position of the support metal 70 is changed (adjusted) in the vertical direction according to the screwing amount. Then, the support metal 70 is brought into a state of being reattached to the support bracket 50 by fastening the bolts 75 inserted into the mounting holes at the positions adjusted in the vertical direction by the spacing adjusting mechanism 110, so that the support metal 70 is vertically and vertically aligned. The position of the direction is adjusted.

In the warp delivery device 20, as described above, the distance between the two easing rolls 33 and 36 supported by the common support structure in the vertical direction is set in the vertical direction in consideration of the type of warp and the like, and other weaving. It is set so that weaving can be performed properly in relation to the elements. Therefore, in the warp sending device 20, the work of adjusting the interval may be performed according to the change of the type of warp or the like.

Regarding the adjustment, in the warp delivery device 20 of the present embodiment, the adjustment of the interval adjusts the position of the second support shaft 34 supporting the second easing roll 36 in the vertical direction, that is, This is done by adjusting the vertical position of the support metal 70 with respect to the support bracket 50. Specifically, the mounting position of the support metal (second support portion) 70 with respect to the base portion 51 of the support bracket 50 is adjusted in the vertical direction by using the interval adjusting mechanism 110 described above. As a result, in the support structure, the position of the second support portion 70 in the vertical direction is adjusted with respect to the first support portion 52 whose vertical position is determined in relation to the base portion 51. As a result, the second support shaft 34 (second easing roll 36) supported by the second support portion 70 and the first support shaft 31 (first support shaft 31) supported by the first support portion 52. The distance from the easing roll 33) in the vertical direction is adjusted.

(4) Regarding the two warp beams provided in the warp delivery device, in the above embodiment, the warp beams 21 and 22 are arranged so as to be mainly positioned differently in the vertical direction. However, in the warp sending device of the present invention, the two warp beams may be arranged so as to be mainly different in position in the front-rear direction as shown in FIG. 5, for example. The configuration of the warp sending device shown in FIG. 5 is as follows in detail. However, in FIG. 5, the same reference numerals are given to the portions having the same configuration as that of the above embodiment, and the description thereof will be omitted below.

In the warp sending device 20'shown in FIG. 5, each side frame 11'in the loom frame 10' has a main body frame 12 having the same configuration as that of the above embodiment and a sending frame 13'separate from the main body frame 12. It is composed of. Further, each transmission frame 13'is composed of two partial transmission frames, each of which is provided separately, as in the above embodiment.

Regarding the two partial transmission frames, the partial transmission frame 13a, which is one of the two partial transmission frames, is the same as the lower transmission frame 13a of the above embodiment in terms of its configuration and arrangement with respect to the main body frame 12. On the other hand, the other partial delivery frame 13c is located behind the partial delivery frame 13a so that the two warp beams 21 and 22 are arranged at different positions in the front-rear direction as described above. It is arranged at a position away from the frame 13a. As described above, the loom frame in the present invention is not limited to the one that is integrally combined as in the above embodiment and the one that is integrally molded as described above, and a part of each side frame is used for other parts. Including those configured to be provided apart. In the following, the one partial transmission frame 13a will be referred to as a front transmission frame, and the other partial transmission frame 13c arranged behind the partial transmission frame 13a will be referred to as a rear transmission frame.

The warp beam 21 is supported by the pair of front delivery frames 13a and 13a by the beam guides 14a and the beam guides 14c provided on the front delivery frame 13a and the rear delivery frame 13c, respectively, and the warp beams 22 are paired. It is supported by the rear transmission frames 13c and 13c. As a result, the two warp beams 21 and 22 are arranged at different positions in the front-rear direction.

Incidentally, in the illustrated example, the two warp beams 21 and 22 are arranged so as to be slightly different in position in the vertical direction. However, since the difference in arrangement in the vertical direction is very small compared to the difference in arrangement in the front-rear direction, in this example, the two warp beams 21 and 22 are arranged so as to be (mainly) different in position in the front-rear direction. It is considered to be an example. Even when the loom frame is configured as shown in FIG. 5, the warp delivery device is configured so that the two warp beams 21 and 22 are arranged at the same position in the vertical direction. Is also good.

In the illustrated example, the support shaft 31 of the easing mechanism 30a corresponding to the warp beam 21 and the support shaft 34'of the easing mechanism 30c corresponding to the warp beam 22 are supported by a support structure mainly composed of the support bracket 50'.

It is attached to the existing part. As a result, the easing roll 36'in the easing mechanism 30c is arranged behind and above the easing roll 33 in the easing mechanism 30a.

In the illustrated example, the warp sending device is positioned so that the easing roll 36'corresponding to the rear warp beam 22 is located behind and above the easing roll 33 corresponding to the front warp beam 21 as described above. This prevents the path of the warp drawn from the warp beam 22 on the rear side intersecting the path of the warp drawn from the warp beam 21 on the front side, and prevents both warp threads from sliding at the intersection position. To do. In this way, in the warp sending device in which the two warp beams are arranged so as to be in different positions in the front-rear direction, the easing roll corresponding to the warp beam on the rear side is larger than the easing roll corresponding to the warp beam on the front side. It is desirable to be placed rearward and above.

However, when the sliding contact between the warp threads as described above is allowed, for example, in the configuration shown in FIG. 5, the easing roll 33 located in the front corresponds to the warp beam 22 on the rear side and is positioned rearward and upward. The warp delivery device 20'may be configured so that the easing roll 36'corresponds to the warp beam 21 on the front side. That is, the warp drawn from the front warp beam 21 is wound around the easing roll 36'of the easing mechanism 30c, and the warp drawn from the rear warp beam 22 is wound around the easing roll 33 of the easing mechanism 30a. You may.

Further, in the example of FIG. 5, the support structure is attached to the main body frame 12 of each side frame 11'in the loom frame 10'as in the above embodiment, but the transmission frame of each side frame 11' It may be attached to the rear transmission frame 13c at 13'. In that case, the support structure is oriented so that its base 51'is located behind the first support 52', and the support structure is mounted in the vertical direction with respect to the front end surface of the rear delivery frame 13c. Can be installed adjustable.

Further, in the example of FIG. 5, in each side frame 11'of the loom frame 10', the separate front side sending frame 13a and the rear side sending frame 13c constituting the sending frame 13'are arranged apart from each other in the front-rear direction. Has been done. However, in the loom in which the two warp beams in the warp delivery device are arranged so as to be displaced in the front-rear direction, the delivery frame is divided into a partial delivery frame corresponding to the front delivery frame 13a and a rear delivery frame 13c. It may be configured in such a way that the corresponding partial transmission frame is integrally combined. Further, the sending frame may be integrally molded so as to include a portion corresponding to the front sending frame 13a and a portion corresponding to the rear sending frame 13c.

Further, in the above, the example in which the two warp beams in the warp delivery device are arranged so as to be different in the vertical direction or the front-rear direction has been described, but in the warp delivery device of the present invention, the two warp beams have been described. May be arranged so as to have different positions in both the vertical direction and the front-back direction.

Specifically, for example, the rear transmission frame 13c in the example of FIG. 5 may extend further upward than the illustrated example, and the warp beam 22 may be supported at the upper end thereof. In the case of this configuration, the support shaft 34'in the easing mechanism 30c corresponding to the warp beam 22 is provided as a dedicated shaft, and accordingly, the guide roll corresponding to the warp beam 22 is a dedicated guide roll. As a result, it is provided between the easing roll 36'and the warp beam 22 in the vertical direction.
