DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a spring hanger structure for a dobby machine.

[0002]

2. Description of the Related Art FIG. 6 shows an outline of a loom equipped with a dobby machine. As shown in the figure, the loom 1 includes a pair of looms 3, 3 erected on a floor 2 at predetermined intervals, and a plurality of looms (3) disposed between the looms 3, 3 so as to overlap in the front and back direction of the drawing. (About 8 to 16 sheets) of the heald frames 4, and by appropriately raising and lowering these heald frames 4 by a dobby machine 5 described later, each heald frame 4
Weaving is performed by opening the warp thread inserted and held in the opening and passing the weft thread through the opening.

[0003] The dobby machine 5 pulls a wire W connected to each heald frame 4 down or down appropriately against a spring 6 to thereby obtain a desired heald frame 4.
Is raised or lowered as appropriate to control the opening of the warp yarn. The wire W connected to each heald frame 4
An upper spring hanger 8 is provided via a swing arm 7 whose upper end is swingably supported on the top of the loom frame 3.
(Made of resin), the lower end is connected to the jack lever 11 in the dobby casing 10 via the pulley 9, and a predetermined tension is applied.

The upper spring hanger 8 is connected to a lower spring hanger 12 via a spring 6. Lower spring hanger 12 is fixed bracket 1
It is fixed to the loom frame 3 via the pin 3 and the pin 14. On the other hand, the jack lever 11 is appropriately swung around the shaft 16 by a known link lever mechanism 15 or the like accommodated in the dobby casing 10 to pull or loosen the wire W. The same number of the swing arms 7, the upper spring hanger 8, the lower spring hanger 12, the spring 6, the pulley 9, and the jack lever 11 as the heald frame 4 are arranged so as to overlap in the front and back directions on the paper.

According to the above configuration, the heald frame 4
When the jack lever 11 is rotating in the direction to loosen the wire W (counterclockwise in the figure), the jack 6 is pulled upward by the spring 6 and is in the raised position. When it turns in the pulling direction (clockwise direction in the drawing), it is pulled down to the lowered position. Therefore, by rotating the desired jack lever 11 as appropriate, the desired heald frame 4 can be raised and lowered as appropriate, and the opening of the warp can be controlled to change the weaving pattern at the time of weaving.

[0006]

By the way, in the above-mentioned dobby machine 5, since the upper spring hangers 8 are arranged so as to be overlapped in the front and rear directions of the drawing and are in contact with each other, when each heald frame 4 moves up and down. In this case, the contact portions of the upper spring hangers 8 and 8 come into sliding contact with each other. Although there is no problem in strength, there is a problem that the contact portions are worn.

As a countermeasure, an attempt has been made to apply grease to the contact portion or to form a concave portion to accommodate the grease therein, but it cannot be said that a sufficient wear resistance effect has been obtained. In addition, the fly waste generated during weaving may be caught in the grease, and the adjacent hangers 8, 8 may bite each other, making it difficult to properly lift and lower the heald frames 4, 4, that is, to make the normal operation of the loom 1 difficult. There is also.

SUMMARY OF THE INVENTION An object of the present invention, which has been made in view of the above circumstances, is to provide a spring hanger structure of a dobby machine in which a contact portion between spring hangers is improved in wear resistance.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a spring hanger structure of a dobby machine in which adjacent spring hangers are brought into contact with each other, wherein the contact portions of adjacent spring hangers are different from each other. It is made of material.

Preferably, the contact portion is formed in a convex shape so as to be the only contact sliding portion between adjacent spring hangers.

It is preferable that the material of the contact portion be a resin and a metal between adjacent spring hangers.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the accompanying drawings.

The spring hanger structure of the dobby machine according to the present embodiment is used for the loom 1 shown in FIG. 6 described above, and has a basic structure similar to that of the spring hanger structure 17 shown in FIG. ing.

That is, the spring hanger structure 1
Reference numeral 7 denotes an upper spring hanger 8 to which a wire W connected to the heald frame 4 is connected, a spring 6 connected to the upper spring hanger 8, and a spring 6 to be connected to the spring 6, as also shown in FIGS. The lower spring hanger 12 and the lower spring hanger 12
A fixed bracket 13 attached to the loom frame 3 for pivotal support via the upper 4 and the upper spring hanger 8, the spring 6, and the lower spring hanger 12;
In FIG. 6, the same number as the number of the heald frames 4 are arranged so as to be superimposed on the front and back sides of the paper.

As shown in FIG. 2, the upper spring hanger 8 includes a horizontal portion 18 and vertical portions 1 provided at both ends thereof.
9 and 19. As shown in FIG. 4, a plurality of slits 20 are formed in the horizontal portion 18 at predetermined intervals in the horizontal direction, and a rod 21 is provided to pass through the slits 20. An upper hook 22 of the spring 6 is hooked on each slit 20. On the other hand,
The lower spring hanger 12 has the same configuration as the upper spring hanger 8, and the spring 6 is attached to the rod 21 of each slit 20 of the lower spring hanger 12.
Are hooked respectively (see FIG. 1).

A bracket 24 is attached to the horizontal portion 18 of the upper spring hanger 8, and a wire W connected to the heald frame 4 is connected to the bracket 24. On the other hand, a bracket 25 is also attached to the horizontal portion 18 of the lower spring hanger 12, and the bracket 25 is pivotally supported by a fixed bracket 13 attached to the loom frame 3 via a pin 14. That is, a pair of the upper spring hanger 8, the spring 6, and the lower spring hanger 1 in FIG.
2 corresponds to one heald frame 4 shown in FIG. The spring hanger structure 17 having such a configuration is covered with the fly waste prevention casing 26.

As shown in FIGS. 2 and 3, the vertical portion 19 of the upper spring hanger 8 is provided with contact portions 27a and 27b formed in a convex shape. Contact portions 27a, 2
7b is formed to a thickness such that adjacent upper spring hangers 8, 8 are in contact only at their contact portions 27a, 27b. That is, as shown in FIG.
The thickness L1 of the vertical portion 19 including 7a and 27b is set to be thicker than the thickness L2 of the horizontal portion 18. Such a setting is made between adjacent horizontal portions 18, 18.
It is also possible to secure a space where the springs 6 attached to the fin 8 do not interfere with each other.

The contact portions 27a and 27b are made of metal (SPC) on the one surface side of the upper spring hanger 8.
C, etc.) and the other side 27b is made of resin (PO
M, polyacetal, etc.). Therefore, the material of the contact portions 27a and 27b of the adjacent upper spring hanger 8 is a different material (metal or resin) as shown in FIGS. Therefore, sliding resistance (wear)
Becomes smaller. The contact portions 27a and 27b may be fixed to the vertical portion 19 by screwing, bonding, or the like. However, it is preferable that the contact portions 27a and 27b be integrally attached when the upper spring hanger 8 is subjected to injection molding or the like.

In the present embodiment, the contact portions 27a and 27b are formed with a depression 28, as shown in FIG. 2, so that a lubricant such as grease can be stored in the depression 28. However, the depression 28 is not always necessary. Because the material of the adjacent contact portions 27a and 27b is different from that of metal or resin, the sliding resistance (wear) between the contact portions 27a and 27b can be sufficiently reduced without using a lubricant such as grease. Because.
Therefore, even if grease or the like is stored in the recess 28, only a very small amount is required.

On the other hand, in the present embodiment, the lower spring hanger 12 also has the same configuration as the upper spring hanger 8 as shown in FIG. 5, and contact portions 27a and 27b are attached to the vertical portion 19 thereof. As shown in FIG. 1, the contact portions 27a and 27b are arranged so as to be in contact with each other. However, as shown in FIGS. 1 and 5, the lower spring hanger 12 is pivotally supported by the fixed bracket 13 with the pin 14 and does not move up and down. Therefore, like the upper spring hanger 8, the contact portions 27a and 27b slide together. There is no resistance (wear) problem.

For this reason, it is not necessary to attach the contact portions 27a and 27b for reducing the sliding resistance (wear) to the lower spring hanger 12 unlike the upper spring hanger 8, and all of them are theoretically entirely the same. It is only necessary to perform injection molding integrally with the material, but in that case, two types of hanger molding of the upper spring hanger 8 and the lower spring hanger 12 are required, which increases the cost. Therefore, in this embodiment, The same shape as the upper spring hanger 8 is also used as the lower spring hanger 12 to reduce the cost.

The operation of this embodiment having the above configuration will be described.

When the upper spring hanger 8 moves up and down as shown in FIG. 1 in response to the swinging of the jack lever 11 in the dobby casing 10 shown in FIG. 10, the contact portions 27a between the adjacent upper spring hangers 8 and 8, Since the material of 27b is different from metal or resin, the sliding resistance (wear) between the contact portions 27a and 27b is reduced, and the wear resistance is improved.

Further, since it is not necessary to use grease (or even if it is used, only a very small amount is required), it is possible to prevent (or suppress) fly waste generated during weaving from being caught in the grease. Therefore, it is possible to avoid the problem of the bites between the adjacent hangers 8, 8 caused by the fly cotton getting caught in the grease, and to secure the proper operation of the heald frames 4 and the normal operation of the loom 1, reliability·
The durability is improved.

[0025]

As described above, according to the spring hanger structure of the dobby machine according to the present invention, the wear resistance of the contact portions between the spring hangers can be improved.
