BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temple device in a loom, and more particularly to a throwing ear guide member provided in the temple device.

[0002]

2. Description of the Related Art Conventionally, in a loom, a temple device is provided near the cloth fell W1 in order to prevent the cloth W from shrinking. For example, FIG. 7 shows a temple device 20 provided on the opposite side of the weaving machine. A substantially conical head portion 22 and a substantially cylindrical tail portion 23 each having a notch in the lower portion are fixed to both ends of the support shaft 21, and the head portion 22 and the tail portion 23 are fixedly supported near the cloth fell W1 by the bracket (not shown). Has been done. A plurality of temple rings 24 having needles (not shown) provided on the surface between the head portion 22 and the tail portion 23 are arranged in the axial direction of the support shaft 21 as described in, for example, Japanese Patent Laid-Open No. 174057/1993. It is rotatably supported by a support body (not shown) inclined with respect to. The temple ring 24 comes into contact with the lower surface of the woven cloth W and pulls the woven cloth W laterally while being driven and rotated to prevent the woven cloth W from shrinking (the woven cloth W on the temple ring 24 is not shown). Only the temple rings 24 at both ends are shown in the figure, and the temple device 20 is fixedly arranged so that the temple ring 24 closest to the tail 23 is located at the woven fabric end W2.

A guide groove 25 having a substantially semicircular cross section for guiding the throwing edge We is formed in the tail portion 23 of the temple device 20. The guide groove 25 is a warp Te for throwing away
It is located slightly on the anti-weft insertion side than the position of
Is biased toward the reverse weft insertion side to apply tension to the woven weft yarn immediately after beating. Warp T
A transmissive feeler 26 for detecting a weft is fixedly arranged on a sley (not shown) between the warp yarn Te and the waste yarn Te.

[0004]

[Problems to be Solved by the Invention] Warp T and warp T
The optimum value of the interval e varies depending on the type of feeler. For example, compared with a transmission type feeler, a reflection type feeler generally has a wider width in the weft inserting direction because the projector and the light receiver are arranged side by side in the weft inserting direction.When using a reflection type feeler, when using a transmission type feeler. Compared with this, the space between the warp and the throw-off warp must be increased. Further, the optimum spacing between the warp T and the warp yarn Te for sewage differs depending on the type of yarn used for the warp and the weft. Generally, the larger the distance between the warp yarn T and the warp yarn Te for throwing away yarn, the more the traction force applied to the weft yarn by the sub-nozzle increases and the structure of the woven fabric W becomes stable, but the amount of the weft yarn also increases. Therefore, the space between the warp yarn T and the throwing warp yarn Te should be as small as possible within a range in which the weft yarn does not loosen in accordance with the type of yarn (e.g., easiness of receiving traction force by the air flow of the sub-nozzle or easiness of contraction of the yarn). Is preferable in terms of production cost.

However, even if the distance between the warp yarn T and the warp yarn Te for throwing away is changed, the position of the temple ring 24 on the side opposite to the weft insertion must be aligned with the woven fabric edge W2. However, since the guide groove 25 is displaced together with the temple ring 24, the temple device 20 itself cannot be moved in the weft inserting direction. Therefore, the warp thread T and the warp thread T for dismounting
The positional relationship between the throwing edge We and the guide groove 25 is changed by changing the interval of e, and the tension applied by the guide groove 25 to the throwing edge We changes. That is, the warp yarn T and the warp yarn Te for the selvage yarn
If the distance between the guide grooves 25 is small, the tension applied to the waste ears We may be large, and the waste ears We may come off from the guide groove 25. Conversely, if the distance between the warp T and the warp Te for waste ears is increased, the guide The tension applied by the groove 25 to the selvage We is insufficient and the weft is loosened, so that the good woven fabric W cannot be formed.

The present invention has been made in view of the above problems, and an object thereof is to always apply an appropriate tension to the waste thread even if the distance between the warp thread and the waste thread for the waste thread is changed. (EN) Provided is a temple device having a disposable ear guide member.

A substantially conical head 4 having a notch in the lower portion and a substantially annular positioning ring 5 are fixed to the support shaft 3, and the head 4 and the support shaft 3 are provided with brackets (not shown) at the ends on the opposite side of the weft insertion side. It is fixedly supported near the cloth fell W1. Between the head 4 and the positioning ring 5, a plurality of temple rings 6 having needles (not shown) implanted on the outer peripheral surface thereof are rotatably supported by a support (not shown). The temple ring 6 abuts the lower surface of the woven fabric W and pulls the woven fabric W laterally while being driven to rotate to prevent the woven fabric W from shrinking (the woven fabric W on the temple ring 6 is not shown). . The temple ring 6 closest to the positioning ring 5 is the woven fabric edge W2.
The temple device 2 is fixedly arranged so as to be located at. The head 4, the positioning ring 5, and the temple ring 6 form a main body 7 of the temple device 2.

It is mounted on a mounting bracket (not shown). A guide groove 10 as a guide portion having a substantially semicircular cross-sectional shape is formed in a clockwise spiral shape on the outer peripheral surface of a cylindrical ear piece guide member 8 having an outer diameter equal to that of the positioning ring 5. The upper edge of the guide groove 10 is chamfered. The throwing edge We is deflected and guided along the guide groove 10 to the side opposite to the woven fabric W to give proper tension, and after passing through the guide groove 10, it is taken out by a throwing edge processing mechanism (not shown). A transmissive feeler 1 for weft detection is fixedly arranged on a sley (not shown) between the warp yarn T and the warp yarn Te for throwing away.

Next, the operation of the apparatus configured as described above will be described. The woven cloth W is taken up by a surface roller (not shown) while being in contact with the upper surface of the temple ring 6. As the woven cloth W is taken up, the end of the woven cloth W is guided while being pulled laterally by the action of the temple ring 6. Further, the throwing edge We formed on the side of the woven cloth W is deflected and guided to the opposite side of the woven cloth W at the upper part of the guide groove 10 formed on the outer peripheral surface of the throwing edge guide member 8, and the throwing edge processing (not shown) is performed. It is taken over by the mechanism. Adjusting the engagement position of the guide groove 10 with the throwing edge We in the longitudinal direction of the temple device 2 by releasing the fixing of the throwing edge guide member 8 to the spindle 3 and rotating it with respect to the spindle 3. You can

For example, as shown in FIG. 2, when the transmissive feeler 1 in FIG. 1 is changed to the reflective feeler 11, the interval between the warp T and the selvage warp Te is changed. When the distance between the warp yarn T and the warp yarn Te for throw-away yarn is changed, it is necessary to change the position of the engaging portion of the guide groove 10 with the throw-away yarn We. At the time of this work, the worker loosens the screw 9 to make the throwing-edge guide member 8 rotatable with respect to the support shaft 3. Next, the throwing edge guide member 8 is appropriately rotated so that the position of the guide groove 10 matches the position of the throwing edge We after the change, and the screw 9 is tightened at the position where the position of the guide groove 10 matches the position of the throwing edge We. Support shaft 3
It is fixed so that it cannot rotate. The weft thread We is the warp T of FIG.
Since the deflection guide is performed in substantially the same state as before the change of the interval between the warp yarn Te for throw-away and the warp yarn Te, the tension applied to the throw-off yarn We
And, there is no change before and after the change of the interval of the warp yarn Te for throwing away.

This embodiment has the following effects. (A) Since the engagement position of the guide groove 10 of the throw-away guide member 8 with the throw-away We can be adjusted in the longitudinal direction of the temple device 2, even if the interval between the warp T and the throw-away warp Te is changed. It is possible to form a good woven fabric W by always applying the optimum tension to the throw-back ear We.

(B) Since the waste ears are guided by the guide groove 10 formed on the outer peripheral surface of the waste ears guiding member 8,
Since there is no protruding portion at the portion that abuts between the throwing edge and the woven cloth, the woven cloth guided on the temple device 2 is not adversely affected.

(C) Since the guide groove 10 is spirally formed on the peripheral surface of the throwaway ear guide member 8, the guide groove 10 can be easily rotated by rotating the throwaway ear guide member 8 without removing it from the support shaft 3. It is possible to adjust the position of engagement with the discarded ear We. Therefore, when adjusting the position of the guide groove 10, it is not necessary to release the fixation of the end portion of the support shaft 3 on the side opposite to the weft insertion side to the bracket (not shown). In addition, the guide groove 10 has
Since it is inclined in the deflection guide direction with respect to, the throw-away ear We can be smoothly guided in the take-up direction to the throw-away processing mechanism (not shown).

(D) Since the guide groove 10 has a substantially semicircular cross-sectional shape and the upper edge thereof is chamfered, a large tension is not applied to the throwing edge We and it is weak. Even when a thread is used, it is possible to smoothly guide the throw-off ear We without causing thread breakage.
