Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a structure for attaching a heald used as a shedding device of a loom to a heald frame.

<Conventional technology> Conventionally, this type of mounting structure was
As shown in Publication No. 6531, mounting portions are formed at both ends of the heald, and these mounting portions are inserted into locking grooves formed into narrow tapers through slits in the upper and lower cross beams of the heald frame. There is a known device that locks the device by letting it move. In this case, after inserting the mounting part of the heald into the locking groove through the slit, the heald is rotated around its axis so that the mounting part is held on the cross beam, and the heald is fixed. It is attached to the heald frame.

<Problems to be Solved by the Invention> However, when attaching the heald to the heald frame in this way, the attachment part is inserted into the locking groove through the slit and then rotated around the axis to attach it. The heald device requires two steps: inserting the heald mounting part into the locking groove through the slit, and rotating the heald around its axis.
There was a problem that only one tube could be attached at a time, and since it required two steps, it took time and effort to attach one tube at a time.

The present invention was made in view of these problems, and an object of the present invention is to facilitate the mounting of healds on a heald frame.

<Means for Solving the Problems> For this reason, the present invention forms an open end portion of a locking groove, and a blocking piece for regulating movement of the heald to this open end portion is detachably attached to the heald frame. The configuration is such that

<Function> According to the above structure, since the open end of the locking groove is formed, the heald can be easily attached by applying the attachment part of the heald to the open end and pushing it in. In addition, the closing piece can prevent the heald from moving toward the open end, thereby preventing it from falling off after being installed.

(Example) Examples of the present invention will be described below based on the drawings.

1 to 4 show a first embodiment of the present invention.

To explain the configuration, the heald frame 11 has upper and lower cross beams 1.
Consisting of 2a, 12b and side frames 13a, 13b,
Narrow locking grooves 14a, 14b are formed on opposing surfaces of the upper and lower cross beams 12a, 12b. Locking groove 1
4a, 14b are rectangular fitting holes 15a, 15b extending in the longitudinal direction of the cross beams 12a, 12b, and slits 16a, which are continuous with the fitting holes 15a, 15b and open in the opposing surfaces.
16b, therefore the slits 16a,
Both sides of 16b become locking parts 17a and 17b.
In addition, these locking grooves 14a and 14b are connected to the cross beam 12.
A and 12b may be formed by extrusion molding of aluminum or the like.

Further, near the longitudinal ends of the cross beams 12a, 12b, notched grooves 18a, 18b are formed which are cut out from the opposing surface side, penetrate in the front-rear direction, and cross the locking grooves 14a, 14b. . Here, the notch grooves 18a, 18b are the locking grooves 14.
It forms the open end of a and 14b. The notch grooves 18a and 18b are formed by screws 1 on the side frame 13a.
Almost Z-shaped closing piece 20 fastened by 9a and 19b
It is designed to be closed by the tip portions of a and 20b.

The heald 21 has a mail hole 22 for inserting warp threads in the middle part of a plate-shaped metal member made of stainless steel or the like.
Rectangular mounting portions 23a and 23b are formed at both ends by injection molding of plastic. Incidentally, it is desirable that both ends of the plate-shaped metal member have a shape suitable for preventing the plastic part from coming off.

Therefore, when attaching the heald 21 to the heald frame 11, the attachment parts 23a and 23b of the heald 21 are attached to the cross beam 12 with the closing pieces 20a and 20b removed.
a, 12b, and when they match with the fitting holes 15a, 15b of the locking grooves 14a, 14b, they are shifted in the longitudinal direction of the cross beams 12a, 12b and attached. When all the attachments are completed, insert the tips of the closing pieces 20a and 20b into the notched grooves 18.
a, 18b to block it, screws 19a, 1
Stop at 9b.

According to this configuration, the locking grooves 14a, 14b
Since the attachment parts 23a and 23b of the heald 21 can be attached from the open ends of the healds 21, that is, the notch grooves 18a and 18b, this operation can be easily performed. In this case, the mounting portions 23a, 2 of the plurality of healds 21
If the parts 3b are stacked and mounted integrally, the mounting efficiency will be increased. Further, after mounting, the closing pieces 20a and 20b restrict the movement of the heald 21 toward the open ends of the locking grooves 14a and 14b, that is, toward the cutout grooves 18a and 18b, thereby preventing the heald 21 from falling off.

In addition, since the mounting parts 23a and 23b of the heald 11 are made of plastic, the generation of noise can be suppressed by a buffering effect when the locking grooves 14a and 14b of the cross beams 12a and 12b come into contact with the locking parts 17a and 17b, in particular. It is effective in reducing noise. In this case, the attachment parts 23a and 23b of the heald 21 may be made of hard rubber other than plastic, and are preferably made of a relatively lightweight cushioning material. Furthermore, as shown in FIG. 5, the locking portion 17a may be provided only on one side.

The embodiments shown in FIG. 6 and later restrict the rotation of the healds around their axis in order to prevent the healds from rotating around their axis and falling out of the slits when the density of the healds is small in the aforementioned embodiments. The same parts as those in the previous embodiment are given the same reference numerals, and only the different parts will be explained.

In the embodiment shown in FIGS. 6 and 7, the cross beam 12a
The slit 16 of the fitting hole 15a of the locking groove 14a of
A protrusion 31 is formed in the longitudinal direction on the opposite side of the heald 21, and a groove 32 that fits into the protrusion 31 is formed in a part of the mounting portion 23a of the heald 21. In this way, the rotation of the heald 21 around the axis is restricted by the groove 32 of the attachment portion 23a fitting into the protrusion 31.

In the embodiment shown in FIGS. 8 and 9, the mounting portion 23a of the heald 21 is extended in the front-rear direction outside the slit 16a of the cross beam 12a, and further raised along the front and rear wall surfaces of the cross beam 12a, and the regulating piece 33 is integrated. It was formed in Even if you do this, the heald 21
The rotation of is prevented by the restriction piece 33 coming into contact with the cross beam 12a. Note that the regulating piece 33 may be formed only on either one.

In the embodiment shown in FIG. 10, a plurality of healds 21 are
As a group, these rotations are regulated. That is, one of the pair of healds 21 is provided with a protrusion 34 on its mounting portion 23a, and the other heald is provided with a hole 35 through which the protrusion 34 passes, and the protrusion 34 is inserted into the hole 35. By doing so, a plurality of healds 21 are integrated. In this way, they cooperate with each other to prevent rotation.

The embodiment shown in FIGS. 11 and 12 attempts to restrict the rotation of a plurality of healds 21 by integrating them at their mounting portions. That is, in this example, three plate metal members of the healds 21 are arranged at predetermined intervals, and the ends of these metal members are collectively injection molded with plastic or the like to form an integrated mounting portion 36. . If the width in the longitudinal direction of the cross beam 12a of the mounting portion 36 is increased in this manner, even if the mounting portion 36 attempts to rotate within the fitting hole 15a, the rotation is blocked by the wall surface, so that rotation can be prevented.

The embodiment shown in FIG. 13 and FIG.
A fork-shaped mounting portion 37 made of a cushioning material such as plastic or hard rubber is formed at the end of the cross member 1, and the locking groove 14a' on the side of the cross beam 12a is also shaped to correspond to this. With such a configuration, even if the attachment part 37 tries to come out of the locking groove 14a' due to the tension of the warp threads, the locking part 17a' is an inclined plane, so it will be bent inward, and the fitting hole 15a' will be bent inward. Since the upper narrowed portion moves inward and engages with the slope of the protrusion 31', it will not contract any further and the heald 21 can be effectively prevented from coming off. Of course, the protrusion 31' is the heald 2.
1 can be prevented from rotating.

<Effects of the Invention> As explained above, according to the present invention, the heald can be mounted on the heald frame simply by inserting the mounting portion of the heald into the open end of the locking groove, and the mounting operation is one step. , easy to install. Furthermore, since it is possible to attach several attachment parts one on top of the other, the attachment efficiency can be further increased in this way. Furthermore, the closing piece can also prevent the heald from falling off the heald frame after it has been installed.
