Problems solved by technology

However, for example, in the case of weaving a fabric in which the rotation speed of the loom fluctuates during operation like plush, there is a problem that it is difficult to properly set the hardness of the elastic member.
That is, if the resonance frequency changes due to changes in the rotational speed of the loom during operation, the vibration of the end guide supporting column as the remaining warp finishing rod cannot be reduced.

[0024] Hereinafter, an excess warp arrangement rod support device of the loom according to the first embodiment will be described with reference to the drawings. First, a loom provided with an excess warp arrangement rod support device will be described.

[0025] figure 1 The shown loom 10 is an air-jet loom that flies weft yarns (not shown) by compressed air and inserts weft yarns to openings of warp yarns T. As shown in FIG. The loom 10 includes a pair of left and right side frames 11 . exist figure 1 Only one side frame 11 is shown in FIG. A warp beam 12 is provided at the rear of the loom 10 . The warp beam 12 is supported by a shaft support 13 fixed to the rear of the side frame 11 . Many warp yarns T are wound around the warp beam 12 . A cloth take-up shaft 14 supported by a side frame 11 is provided at the front of the loom 10 . The fabric winding shaft 14 is used to wind the woven fabric W.

[0026] The loom 10 includes a warp shedding device 15 for shedding th...

[0045] Next, elastic members according to Modifications 1 to 3 will be described. Such as Figure 5 As shown in (a), the elastic member according to Modification 1 is a cylindrical body 35 with a C-shaped cross section formed of a rubber-based material. The cylindrical body 35 supports the excess warp arrangement rod 24 in a state where the upper part 35A is in contact with the excess warp arrangement rod 24, the lower part 35B is in contact with the support member 31, and the non-sealed space 36 provided between the upper part 35A and the lower part 35B is deformed. . The vibration absorbing direction is the up-down direction as indicated by the arrow F. FIG.

[0046] Such as Figure 5 As shown in (b), the elastic member according to Modification 2 is a bent body 37 formed of a rubber-based material and having an S-shaped cross section. The upper part 37A of the bending body 37 abuts against the excess warp arrangement rod 24, the lower part 37B abuts against the supporti...

Abstract

The present invention provides an excess warp arrangement rod support device for a loom that can reduce vibration of the excess warp arrangement rod even when a fabric is being woven whose rotational speed of the loom fluctuates during operation. In the remaining warp thread finishing rod supporting device (25) of the loom possessed by the loom and having a support bracket (28) supporting the remaining warp thread finishing rod (24) guiding the remaining warp yarn, the The rubber cylinder (29) as an elastic member between the remaining warp yarn finishing rod (24) and the support bracket (28), the rubber cylinder body (29) is to abut against the remaining warp yarn finishing rod (24) The remaining warp finishing rod (24) is supported in a state that there is a non-sealed space (33) between the upper part (29A) of the upper part (29A) and the lower part (29B) abutting against the support bracket (28).

Description

technical field [0001] The present invention relates to an excess warp arrangement rod support device of a loom, and relates to an excess warp arrangement rod support device for a loom that supports an excess warp arrangement rod for arranging excess warp yarns sent out from a warp shaft of a loom. Background technique [0002] In a loom, an excess warp adjustment bar is generally provided in order to arrange the remaining warp yarns among the warp yarns sent out from the warp beam. The remaining warp thread finishing rod is supported by the remaining warp thread finishing rod supporting device. As the prior art of the excess warp arrangement rod support device of the loom, for example, a support device of an end guide support column disclosed in Patent Document 1 is known. In Patent Document 1, the end portion of the end guide support column is in a state of being tightly fitted into the groove of the end guide bracket via a sleeve made of an elastic member. In addition, ...
