Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) This invention relates to a reed positioning device for a loom.

(Prior Art) Conventionally, a lead suitable for a desired fabric is attached to a predetermined position of a lead holder when a weaving is performed as a preparation for weaving. That is, in a shuttleless loom such as a jet loom, since the weft inserting means is mounted on one side of the loom, the distance between the weft inserting means and the warp and thus the end of the reed on the weft inserting side is a predetermined value suitable for weft insertion. Must be set to the value of. The conventional mounting work will be described with reference to FIGS. 4 and 5. When mounting a predetermined lead 3 on a lead holder 2 which is incorporated in the frame 1 for beating motion, a scale 4 is used to remove the lead 3 from the frame 1. Is measured and the lead 3 is adjusted so that the lead 3 is positioned at a specified position, and then the lead 3 is fixed. As shown in FIG. 4, the lead 3 is made by fixing a large number of reed blades 5 with an upper frame 6, side frames 7 and lower frames 8 on both sides, and fitting this into a groove 9 of the holder 2, A fixing piece (holding block) 10 is applied and fastened with a bolt 11 to be fixed to the holder 2. Positioning of the lead 3 is as follows.
This is done by loosening the bolt 11 a little and adjusting it to a specified position, and then tightening the bolt 11. Further, since only the large frame 8 of the reed 3 is fixed to the reed holder 21, the bending due to the beating motion (see the chain line in FIG. 5) of the reed 3 does not exceed a predetermined value in response to the speedup of the loom. The holding frame 10 is used to attach the upper frame 6 to the holder 2. In FIG. 4, 12 is a sled sword shaft, 13 is a warp, 14 is a woven fabric, and 15 is an auxiliary nozzle. In the conventional case, the lead mounting work is carried out in this manner when the machine is mounted.

(Problems to be solved by the invention) However, in this conventional device, the work of positioning the weft insertion side end of the lead and the work of attaching the lead holding block must be performed in cooperation with each other. There was a problem that the work was very troublesome.

This invention aims at solving the above-mentioned problems by providing a reed positioning device for a loom, which pays attention to this problem and makes the work of attaching the leads extremely easy.

[Means for Solving the Problems] (Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides an abutting member at an optimum position on the lead holder of a loom where the weft insertion side end of the lead is located, A lead holding block is provided at a predetermined position with respect to the abutting member.

(Operation) The abutting member is fixed to a predetermined position on the weft insertion side of the lead holder. When the lead is abutted against this abutting member, the position of the lead is first determined. At this time, since the lead holding block is formed in a predetermined positional relationship with the abutting member, the lead is held by the holding portion of the holding block. Next, the fixing pieces are applied and fixed to the leads at appropriate points. As a result, the work of attaching the reed to the holder becomes very easy and easy, and at the same time, the reed can be prevented from falling in the front-back direction of the loom.

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

First, the configuration will be described. Here, the same members as those of the conventional one are denoted by the same reference numerals, and a part of the description will be omitted.

In FIG. 1, the weft insertion nozzle 16 attached to the groove 9 of the lead holder 2 with a screw 17 is a warp yarn which cooperates with the auxiliary nozzle 15 which holds the weft yarn 18 in the auxiliary nozzle holder 19.
Air is flown into the 13 openings for weft insertion.

A lead 3 in which a large number of reeds 5 are integrated with an upper frame 6, side frames 7 on both sides, and a lower frame 8 has a lower frame 8 inserted into a groove 9 and a left end held by a holder.
It is positioned and held at 20, and thus is attached to the lead holder 2. As shown in FIG. 5, the lead 3 is pressed and fixed to the lead holder 2 over substantially the entire length in the longitudinal direction by a plurality of fixing pieces 10 inserted into the groove 9 of the holder 2.

Now, the holder 20 according to this embodiment is shown in FIGS.
It has the shape shown in the figure. That is, the square pole 21
The lower part 22 has a trapezoidal shape having the same cross section as the groove 9 of the lead holder 2 and has two through holes 23 formed therein, and the upper part 24 has a square hole 25 into which the lead upper frame 6 is inserted. The lead upper frame holding portion 26 having a lateral projection is formed. The square hole 25 is formed with a front wall 25F located on the side of the woven cloth 14 and a rear wall 25B separated from the front wall 25F by a distance corresponding to the thickness of the upper frame 6. Further, the holder 20 has an abutting surface 27 of the lead side frame 7 on the lead side, and the abutting surface 27 abuts the lead 3 to perform positioning.
It is the main part of 28. That is, the butting member 28 is composed of the lower portion 22 having the screw hole 23 and the square pole 21 having the butting surface 27, and the lead holding block.
29 is composed of a lower portion 22 having a screw hole 23, a quadrangular prism 21, and a holding portion 26 having a square hole 25. In this embodiment, the abutting member 28 and the lead holding block 29 are the holders 20.
It is configured as an integrally formed product. The holder 20 is fixed to the lead holder 9 by screwing a screw 30 penetrating the through hole 23 into the screw hole 9 of the lead holder. This screw hole is formed in advance so that the abutting surface 27 is located at the optimum position.

Next, the operation of the above embodiment will be described. For example, at the time of mounting, the left end of the upper frame 6 of the lead 3 is inserted into the square hole 25 of the holding portion 26 and is pushed until the side frame 7 abuts on the abutting surface 27.
As a result, the lead 3 is positioned on the weft insertion side with one touch, and the upper frame 6 is restricted from moving in the front-rear direction by the front wall 25F and the rear wall 25B. Furthermore, as shown in FIG.
Tighten the fixing piece 10 by bolting.

Thus, when the weaving is performed, the lead 3 is abutted with the abutting member 28.
Since the abutting surface 27 of 1 can be arranged at a predetermined position on the holder 2 with one touch, and the lead holding block 29 prevents the upper frame 6 of the lead 3 from moving in the front-rear direction.
It is possible to prevent the lead 3 from bending due to the beating motion. Therefore, the operation speed of the loom can be increased.

Although the abutting member and the lead holding block are integrally molded in the above-described embodiment, the both are not necessarily integrated and may be separate,
For example, the two may be in a relationship of being engaged with each other.

[Effects of the Invention] As described above, according to the present invention, the structure is provided with the abutting member at the position where the lead end portion is located on the lead holder of the loom, and the predetermined position is set with respect to the abutting member. Since the lead holding block is provided in relation to the lead holder, the lead upper frame can be held at the same time as mounting the lead at a predetermined position of the lead holder.
