Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention has the following features: The mechanism for attaching the two-ply beam to the weaving machine and passing its warp threads to the weaving device is related to the method.

(Prior art) When a warp beam is attached to the loom and the warp threads are passed through the weaving equipment, a new warp beam is installed in consideration of shortening the time required for the above-mentioned operation, which will improve the operating efficiency of the loom. A work procedure is generally adopted in which the warp threads are inserted into the heald frame and reed in advance. For example, as shown in FIG. 10, the warp beam 1, the heald frame 2 through which the warp threads T are passed, the reeds 3, or the dropper box 4 that accommodates the dropper for detecting warp thread breakage are placed around the warp beam 1. The warp beams 1, heald frames 2, reeds 3, and dropper boxes 4 are placed on the floor or suspended as shown in the figure. In other words, by adopting such a work procedure, it is no longer necessary to tie the warp threads on the new warp beam side and the warp threads on the woven fabric side one by one on the warp path from the warp beam to the heddle frame on the loom. Work time can be shortened.

The tips of the warp threads T passed through the dropper box 4, heald frame 2, and reed 3 can be connected to the woven fabric by connecting the ends of the woven fabric W cut in front of the reed 3 as shown in FIG. Generally, a method is adopted in which a plurality of cuts are made in the direction of the warp threads T, and the tips of the warp threads T are tied to the plurality of cloth pieces ω formed thereby in an appropriate number of pieces.

(Problems to be Solved by the Invention) However, in this method, not only does it take a considerable amount of time to tie the warp threads T and the cloth pieces ω, but also they are tied parallel to the weave width direction. The drawback is that the warp tension at each location must be balanced, which requires extremely high skill.

In addition, since the joint by knotting has an adverse effect such as the generation of wrinkles when winding the woven fabric, the operation of the loom must be stopped before winding the woven fabric around the cross roller, and the joint by tying should be removed. This necessitates the troublesome process of excluding the looms, resulting in a decrease in the operating efficiency of the loom.

Structure of the Invention (Means for Solving the Problems) Therefore, in the present invention, before work, the weaving process passes the warp threads of the full warp beam in advance at least through warp passing members such as the heald frame and the reed, and A piece of woven fabric is provided at the tip of the warp on the front side, and with the woven fabric on the loom cut in the weaving width direction, an empty warp beam and a warp passing member called a heald frame and reed through which the warp of the beam is passed are placed. Remove from the loom,
A method was adopted in which the full warp beam and the warp member through which the warp threads of the beam were passed were mounted on a loom, and the woven fabric piece was connected to the cut end of the woven fabric on the loom side by sewing, gluing, etc. .

(Function) In other words, in the preparatory stage before work, the heald frame,
By passing the warp threads of the full warp beam through the reed and providing a piece of woven fabric at the tip of the warp thread, it is possible to cut the ra ta woven fabric that requires warp beam replacement in the weaving width direction on the front side of the reed. After removing the empty warp beam and the warp member from the loom, attach the full warp beam and the warp member to the loom, and connect the woven fabric piece to the cut end of the woven fabric by sewing, gluing, etc. Work in process is completed. The woven fabric pieces can be easily connected to the woven fabric on the loom side by sewing, gluing, etc., and the warp side and the woven fabric side can be easily connected in a straight line. The warp tension balance setting is easily and appropriately performed.

Following the state shown in Fig. 3, the full warp beam 1 is attached to the weaving device in place of the empty warp beam 11 as shown in Fig. 4, and the warp threads T of the full warp beam 1 are tied to the cut ends of the warp threads T1. They are tied together one by one using a machine or the like. In this state, the woven fabric (2) is wound up by a predetermined amount on the winding roller 13 side, and the knot K between the warp threads T and warp threads TI is moved to the front of the weaving device as shown in FIG. In this state, the weaving device is operated to perform roughing, and a woven fabric piece w1 is formed as shown in FIG. Then, as shown in the figure, after the appropriate parts of the woven fabric piece W1 are cut, the full warp beam 1, dropper box 4, heald frame 2, and reed 3 are removed from the weaving apparatus together with the woven fabric piece Wl, and the machine The work in progress is stored in the preparation room.

The loom work is stored in the preparation room, and the full warp beam 1 and the through members 2, 3.4 are carried to the loom that requires warp beam replacement, and the full warp beam 1 is stored as shown in Fig. 7.
and the threading members 2, 3.4 are attached to the loom. Then, the woven fabric piece W1 and the woven fabric W are sewn and connected using the FFI manufacturing device 12 as shown in FIGS. 1 and 7. Thereafter, the loom is operated with appropriate tension applied to the warp threads T, and after the sewing connection portion passes between the press roller 8 and the surface roller 9, the tension during normal operation is applied to the warp threads T.
The original weaving is carried out.

In this embodiment, the connection of the warp threads T to the woven fabric W on the loom side is performed through the sewing connection between the woven fabric piece W1 and the woven fabric W, so it can be completed easily and in a short time, and the operation of the loom can be completed easily. Increased efficiency. Moreover, the warp T side and the woven fabric W side can be easily connected linearly through the woven fabric piece W1, and the tension balance of the warp T at each location in the weaving width direction can be easily and appropriately set. be exposed. Therefore, uneven weaving due to warp tension imbalance in the weaving width direction does not occur.

The connection between the woven fabric piece W1 and the woven fabric W is wound around the cross roller 26 as it is woven, but unlike the conventional knotted connection, the woven fabric is wound around the cross roller 26 as it is woven. There is no fear that the connecting portion will have an adverse effect on the winding condition, such as the occurrence of winding wrinkles, and the woven fabric can be wound up smoothly. Therefore, instead of the troublesome process of removing the connection part, which is required in the conventional connection method of tying the warp threads to the fabric side, only the simple process of applying tension to the warp threads can be performed, and the machine work can be carried out after 01. The time when the machine stops operating is much shorter. Of course, if the tensile strength of the seamed connection is sufficient to withstand the warp tension value set during normal operation, the loom will apply the set tension value to the warp threads from the time the loom starts operating after work. In this way, the operating efficiency of the loom can be further improved.

Of course, the present invention is not limited to the above-mentioned embodiments. For example, as shown in FIG. If the woven fabric piece W1 and the woven fabric W are heated in a superimposed state, the woven fabric piece W1 and the woven fabric W are bonded together. As an example using thermoplastic synthetic resin, woven fabric piece W
It is also effective to apply a thermoplastic synthetic resin to the l side. The connection between the woven fabric piece W1 and the woven fabric W is not limited to the above-mentioned connection, but adhesives, staples, etc. can also be used.

In the above embodiment, the woven fabric piece W1 was formed on the tip side of the warp T by going through a process of rough weft insertion in the preparation room, but the loom was formed on the tip side of the warp of the full warp beam before the work. The fabric pieces may also be adhesively connected.

Further, in the present invention, it is also possible to exclude the dropper box from the warp threading member by employing an optical detection device as the warp cut detection means.

Effects of the Invention As detailed above, the mechanism of the present invention has the following effects according to the method:
The loom can perform its work efficiently and in a short time, and the warp tension balance can be easily set, and the loom has the excellent effect of improving the operating efficiency of the subsequent loom. play.
