Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention comprises a pair of upper and lower guide bars extending over the entire width of the woven cloth, and a spindle interposed between the guide bars over the entire width of the woven cloth. TECHNICAL FIELD The present invention relates to a selvage selvage guide device in a loom equipped with a bar temple device for preventing weaving shrinkage by bending and guiding a woven fabric between them.

[Prior Art] When a bar temple device of this type disclosed in Japanese Utility Model Publication No. 56-42386 is used in a jet loom, the throwing ears are also sandwiched between the upper and lower guide bars and the spindle to guide the bending. To be done.

[Problems to be solved by the invention] However, in the waste selvage, since the tip of the weft is gripped by the warp having a tension weaker than the warp tension of the woven cloth, the texture formation state of the waste selvage is as strong as that of the woven cloth. In particular, the weft tip of the waste selvedge may be gathered near the cloth fell by the action of pinching and bending between the lower guide bar and the spindle of the woven cloth introduction side, or this weft tip The part may fall out of the ear. If the tips of the weft threads are densely gathered near the cloth fell, it will not be possible to form a good throwing selvage, and the quality of the woven cloth will be adversely affected. Further, if the tip portion of the weft thread comes off, the tip portion of the weft thread cannot be cut and separated by the throw-away separating cutter.

An object of the present invention is to provide a throw-away guide device capable of solving such a problem of the throw-away portion in a loom using a bar temple device.

[Means for Solving the Problems] Therefore, in the present invention, a guide rod for bending and guiding a waste selvedge is arranged near the extension line of a spindle for bending and guiding the woven cloth, and the woven cloth is provided near the guide rod. A guide body is provided for imparting a bending shape similar to the bending shape of No. 1 to the disposition ear, and a gap region is set on the circumferential surface of the guide rod so as not to sandwich the disposition ear.

[Operation] Although the woven fabric is sandwiched between the spindle and the upper and lower guide bars and guided, the throwing tab is bent and guided without being sandwiched between the guide rod and the guide body. In addition, since the bending guide shape of the throw-away ear and the bending guide shape of the woven cloth are similar to each other, there is no great difference between the two paths. Therefore, the weft yarn tip portion of the throw-off portion does not become dense or fall out.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a partial plan view of the weft insertion terminal side of the bar temple device. Reference numeral 1 denotes a lower guide bar, and the lower guide bar 1 has a length equal to or greater than the entire width from the weft insertion start end side of the woven fabric W to the end side of the woven fabric W ₁ . An upper guide bar 2 is mounted on the lower guide bar 1, and an end position of the upper guide bar 2 on the weft inserting end side is set between the woven cloth W and the throwing ears W ₁ .

As shown in FIG. 2, a housing space S is provided between the tip portions of the upper and lower guide bars 1 and 2, and the spindle 3 is housed in the housing space S. Fabric W is introduced jaws 1a of the upper and lower guide bars 1 and 2, the entrance S ₁ between 2a into the accommodation space S, the upper and lower guide bar and wound spindle 3 wound
It is pulled out from the entrance S ₁ between the jaws 1 a, 2 a of the 1, 2 a and guided along the upper surface of the upper guide bar 2. The spindle 3 moves the jaws 1a, 2a by the action of taking up the woven cloth W.
Then, the woven fabric W is sandwiched between the spindle 3 and the jaws 1a, 2a of the upper and lower guide bars 1, 2 by being pressed against. By the sandwiching action and the bent shape of the woven cloth W, weaving shrinkage is prevented.

A holding bracket 4 is erected on the end portion of the lower guide bar 1 on the weft inserting end side, and a guide rod 5 for guiding the throwing tab W ₁ is attached to the holding bracket 4 near the extension line of the spindle 3. In addition to being supported in a cantilever manner, the support shaft 6 is cantilevered in front of the guide rod 5. A guide roller 7 is rotatably supported by the support shaft 6, and the throwing edge W ₁ is guided along the peripheral surface of the guide roller 7. The positional relationship among the jaw portion 1a of the lower guide bar 1, the guide rod 5, and the guide roller 7 is as shown in FIG. 3, and the bent shape of the throwing edge W _{1 is} the bent shape of the woven cloth W shown in FIG. Is set to be similar to. A gap region S ₂ is provided between the guide rod 5 and the lower guide bar 1 and between the guide rod 5 and the guide roller 7 so as not to pinch the throwing edge W ₁ .

The holding stand 4 is tightened and fixed by a bolt 14, and the insertion hole 4a of the bolt 14 is formed in an elongated shape in the front-rear direction. This allows the holding stand 4 to be adjusted in position forward and backward.

The weft Y injected from the main weft insertion nozzle (not shown) into the weft insertion passage 8a of the modified reed 8 is taken over by the relay traction of the auxiliary weft insertion nozzle 9, and the tip of the weft Y is a warp yarn T ₁ Is gripped by. The weft yarn Y gripped by the woven cloth warp thread T and the throw-away warp thread T ₁ is beaten to the cloth fell W ₂ by the deformed reed 8 to form the woven cloth W and the throw-away ear W ₁ . With fabric W is Yuku been taken up by the rotation of the winding roll (not shown), Yuki they are accepted by another withdrawal device捨耳W _1,捨耳W ₁ is cut and separated from the woven cloth W by a cutter (not shown) .

The woven cloth W is guided by being sandwiched between the spindle 3 and the upper and lower guide bars 1 and 2 in the bent shape shown in FIG. 2, and the waste selvedge W ₁ is bent in the bent shape shown in FIG. And the lower guide bar 1 and between the guide rod 5 and the guide roller 7. Drop ear W ₁ is lower guide bar 1
And is guided without being sandwiched between the guide rod 5 and the guide rod 5, and is also guided without being sandwiched between the guide rod 5 and the guide roller 7. Therefore, the tip of the weft thread of the selvage W _{1 having} a structure that is not as strong as the structure of the woven fabric W is not densely gathered near the cloth fell W _{2 due} to the sliding contact with the tip of the lower guide bar 1 or the guide rod 5. . As a result, the formation of the waste ears W ₁ is always performed well, and the quality of the woven fabric W is not deteriorated due to the formation failure of the waste ears W ₁ .

Further, the bending shape of the woven cloth W around the spindle 3 is similar to the bending shape of the disposing selvage W ₁ around the guide rod 5, so that there is no great difference between the paths of W and W _1. . Therefore, the tip of the weft thread does not come off from the dismounting ear W ₁ due to the difference between the two paths, and
W ₁ is well cut and separated.

In FIG. 8, the jaws 1b and 2b of the upper and lower guide bars 1 and 2 in the guide portion of the throw-away ear W ₁ are notched. Due to this notch formation, the sliding contact resistance of the throw away ear W ₁ in the jaw 1b or 2b is reduced.

It is also possible to directly press the small-diameter spindle 11 into the spindle 3 without using the bearing 10.

In FIG. 9, the woven fabric spindle 3 is used as a guide for the throw-away ear, but a gap area S is provided between the spindle 3 and the upper and lower guide bars 1, 2 for guiding the throw-away ear W _1. The jaws of the upper and lower guide bars 1 and ₂ are provided with different shapes for the woven fabric portion and the waste ear portion so as to provide ₂ . The jaws 1c, 2c corresponding to the throw-away ear portion are thinner than the jaw portions 1a, 2a corresponding to the woven cloth portions, so that the jaws 1 of the upper and lower guide bars 1, 2 of the throw-away ear portion are
A gap region S ₂ is formed between c, 2c and the spindle 3.

[Effects of the Invention] As described in detail above, according to the present invention, a guide rod that bends and guides a waste selvedge is arranged near the extension line of a spindle that bends and guides the woven fabric, and the woven fabric is provided near the guide rod. Since a guide body for giving a bending shape similar to the bending shape to the disposing ear is arranged, and a gap area is set on the peripheral surface of the guide rod so as not to sandwich the disposing ear, sliding contact with the disposing ear is performed. While reducing the resistance, it is possible to reduce the path difference between the waste selvage and the woven fabric, and thereby it is possible to prevent the weft yarn tip end portion of the waste selvage from becoming dense and coming off due to the sliding contact resistance.
