Description

[Detailed explanation of the idea] This invention relates to the improvement of a multi-chop box for a loom.

Conventional multi-thread cloth boxes are designed to prevent mixing of weft threads during weaving and to prevent weft threads from protruding on the sides of the box.
The edge of each rack at the entrance/exit side of each rack is surrounded by a connecting rod that connects each rack, so that the weft fed out from the racks in the rack can enter/exit only from the entrance/exit of each rack.

If the opening of the weft threads from the box is divided into sections according to the entry and exit days of each thread in this way, the weft threads will be exchanged (ascent K)! If the shuttle is located below the shuttle race in the box due to movement,
As shown by the chain line B' in FIG. 2, the weft threads extending from the lower string box pass through a detour that bends at the entrance and exit of the string, and as a result, the weft threads are drawn out from the string more than necessary.

As is well known, the yarn is equipped with a weft tension adjustment device.
It also has a function to rewind it if it is extended too much.

However, there is a limit to this permissible range due to the tension exerted on the weft yarns, and if the lowest row of such racks is located at the lowest position in the weft phase exchange movement, the The weft yarns that are let out from the strings are let out beyond this allowable range, and when the string box is raised, the let-out weft yarns are not wound back onto the strings and become relaxed, causing them to droop significantly.

Such loosening of the weft yarns appears as weft irregularities, differences in gloss, and differences in fineness on the surface of the woven cloth, which impairs the quality of the product.

In addition, when using a yarn with a width such as a flat foil yarn as a weft yarn, this yarn may experience a large frictional resistance at the corners of the entrance and exit of the yarn, causing the surface to lose its luster, or the flat foil yarn may lose its surface luster. This causes problems such as thread breakage.

The purpose of this invention is to solve these problems and to provide a multi-thread yarn box that does not loosen the weft threads drawn out from the strings in the string box and does not cause the flat foil threads to break. .

That is, this invention is designed so that the weft, which is unwound from the windings, passes through the side surface of each row of racks, so that the weft can pass through the side surface of each row of racks, and the weft can pass through the winding end of the rack. The weft thread guide member is attached to a multi-row box with both ends thereof fixed to the upper and lower end side plates of the braided yarn through a space sufficient for longitudinal movement of the boards.

Therefore, the weft yarn unwound from the yarn of each yarn box is shuttled from the side surface of the yarn box through the space between the yarn receiving plate and the weft yarn guide member, and is guided through the shortest path onto the yarn tray. It will be destroyed.

Hereinafter, embodiments of this invention will be described based on the drawings.

FIG. 1 is a perspective view showing the configuration of a multi-purpose storage box according to this invention with six storage devices, and FIG. 2 is a front view showing the state in which this storage box is used.

In Fig. 1, 10 is the rack body, 11 is a rack receiving plate for receiving the fins, 12 is a side wall of the shank box formed by bending the ear end of the fin receiving plate 11 upward, and 13 is a rack plate 11 arranged at predetermined intervals. 14 is a frame that incorporates the clamping body 13 and the receiving plate 11; 15 is a fastening screw for firmly fixing these together; 16° and 16' are box guides 17 and 17' (
18 and 18' are the support rods that are rotatably supported on this support base. In the diagram, entry and exit is from the right side.

The multi-hire box 10 made of such a member may have any function or any shape, but the side portions of each tier of the drawer boxes A1 to A6 are drawn out from the sides of the hinges. This side surface is left open so that the weft yarn can freely pass through this side surface.

As shown in FIG.
This is to lead you to the top.

Conventionally, the weft B has passed through a detour that bends at the exit A6' of the thread S6, as shown by the chain line B' in FIG.

On the other hand, in the case 16 according to this invention, the weft B is guided directly onto the shuttle lace 20 from the side surface of the case, so that the weft B paid out from the cases S, to S6 is kept to the minimum necessary level. It can be stopped without straining the weft tension adjustment device of threads S1 to S6.
The tension of the weft yarn B can also be kept within an appropriate range.

30 is a weft guide member that guides the weft B drawn out from the yarns S1 to S6 in the yarn box along the side surface of the yarn box;
Its both ends are the protruding parts 3 of the upper and lower end side plates of the box main body 10.
1.32, and a space 40 is formed between this member 30 and the side surface of each rack, which is sufficient for the weft to move longitudinally through the receiving plate of each rack.

That is, the lowermost tray receiving plate 11 has an entrance/exit portion A.
6' is provided with a protrusion 32 extending laterally, and the entrance/exit part A of the uppermost side plate 11 of the uppermost box is connected to the protrusion 32 extending laterally.
1' is also provided with protrusions 31 extending laterally, and both ends of the weft guide member 30 are connected to these protrusions 3.
1.32 is inserted and held at a predetermined position.

This weft yarn guide member 30 prevents the weft yarn B from coming into contact with a machine (not shown), such as a picker rail, etc., during the phase change movement of the yarn box main body 10, especially by preventing the weft yarn from protruding from the side surface of the yarn box. This is to avoid it.

Therefore, this member 30 should be arranged as close as possible to the person exit A.
1'! Position it on the A6' side.

Although this member 30 is a round bar in the embodiment, it is not limited to this, and may be a flat plate, for example.

Further, the contact surface of this member 30 with the weft B is kept smooth to prevent wear of the weft B.

The reason why such a member 30 is formed integrally with the box body 10 is because the box body 10 repeatedly moves up and down violently.
This is to reduce the contact friction between the weft B and this member 30 as much as possible.

Needless to say, the box main body 10 having such a shape is not limited to the six-piece box shown in the embodiment.

In addition, the rack 10 according to this invention can effectively reduce the length of weft B as the number of rows of racks A□ to A6 increases. For example, if a comparison is made using an 8-piece yarn, there is a difference of approximately 6 to 8 cm in the length of the let-out length between the chain line B' in FIG. 2 and the weft yarn B'' in the standard type.

This difference is extremely effective in preventing the weft from being excessively let out, and even when the drawer main body 10 is switched to the upward motion, the weft that has been let out from the drawer is wound back into the drawer.
Unlike conventional methods, the weft threads are not relaxed.

Furthermore, since the weft is not excessively let out, the tension of the weft can be kept within an appropriate range.

In this way, this invention opens the side surface of each string box so that the weft fed out from the string passes through this side surface, and the weft thread is placed on the side of the drawer entry/exit end of each string box. Since the weft guide member is positioned through a space sufficient for longitudinal movement of the receiving plate, and both ends of the member are attached to the upper and lower end side plates of the hem braid, the weft thread unwound from the sheave in the sheave box is not loosened. , and the flat foil thread is not cut when used.

Furthermore, since the weft guide member is formed integrally with the box main body, the contact friction of the weft with this member can be minimized, and the weft can be prevented from being damaged.
