Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a guiding shuttle for sewing weaving.

[Background of the idea]

A plurality of inductors having weft insertion holes are slidably fitted along the longitudinal direction of the shuttle, and
Guiding shuttles for sewing have been put into practical use for a long time, in which the inductor is pulled in a certain direction by a tension string such as a rubber cord, and the slack in the weft yarn during weaving is absorbed by the sliding motion of the inductor. There is. In conventional sewing guide shafts, the inductor is arranged almost vertically along the side wall, and the weft is taken out from the side, but in order to take out the weft from above, It has been proposed to place the inductor generally horizontally along the top surface of the shuttle. (Refer to Utility Model Application Publication No. 55-80390).

However, in this proposed method, as shown in Fig. 4, the weft yarn d guided from the inductor c is pulled out while being bent greatly toward the opposite side of the shuttle, which creates an unreasonable force for pulling it out. hangs,
In addition, when passing through the opening formed by the warp threads e, the weft threads d come into sliding contact with the warp threads e, resulting in a problem in that the weft threads are likely to break. In addition, in FIG. 4, a is the shuttle body, and b is a woodwind storage space. In order to improve this point, as shown in Figure 5, the inductor c
It has also been proposed to provide the weft threads on the side wall in the direction opposite to the reed side, but even in this case, there is still the problem that the weft threads d are highly bent and easily come into contact with the warp threads e, causing thread breakage. It remains.

[Purpose of invention]

The present invention improves the problems of the prior art as described above, and allows the weft to be pulled out extremely smoothly, without the risk of the pulled-out weft coming into contact with the warp forming the opening and causing yarn breakage. The object of the present invention is to provide a guiding shaft for sewing weaving.

[Summary of the idea]

In order to achieve the above object, the present invention has the upper surface of the side wall of the shuttle body opposite to the reed side inclined so that the outer side is lower, and the inductor is inclined so as to be almost parallel to the inclined upper surface. The present invention is characterized in that it is configured to be slidably fitted into the shuttle main body in this state, and a gap is formed between the weft threads led out from the inductor and the warp thread opening.

[Example of idea]

Hereinafter, an example of the implementation of the present invention will be specifically explained with reference to FIGS. 1 to 3.

Figure 1 is an enlarged sectional view taken along the - line in Figure 2;
FIG. 2 is a plan view.

In these figures, 1 is the shuttle body, 1
a is a woodwind storage space formed in the shuttle body;
2 is a woodwind removably attached to the tongs, and 3 is a well-known weft tensioner.

In the present invention, the upper surface 1c of the side wall 1b of the shuttle body 1 on the opposite side to the reed side is inclined so that the outer side is lower, and the inductor 4 is inclined so as to be substantially parallel to the inclined upper surface 1c. Fits slidably into the main body. That is, the side wall 1b of the shuttle body 1 is thicker than the other side wall, and has an outwardly inclined guide space 5 formed therein in the longitudinal direction. A pair of guide grooves 6 (three sets in FIG. 1) are formed on the inner wall surface, and the inductor 4 is slidably fitted into each of the guide grooves 6. As is well known, each inductor 4 has a weft insertion hole 4.
A tension cord 6 such as a rubber cord having one end fixed 6a to the shuttle body is pulled out in the opposite direction via a pulley 7, the other end is fixed to the inductor 4, and the inductor 4 is pulled outward. ing. The weft d pulled out from the woodwind 2 passes through a normal weft tensioner 3, and then is sequentially inserted into each insertion hole 4a of a plurality of inductors 4, and finally ends up in the uppermost inductor 4.
is pulled out from the insertion hole 4a.

Since the guide shaft for sewing and weaving of the present invention is constructed as described above, the weft yarn d is pulled out almost along the sloped upper surface 1c as shown in FIG. Moreover, since a gap G is formed between the inclined upper surface 1c and the warp threads e constituting the opening, it is possible to eliminate the possibility that the weft threads d will come into sliding contact with the warp threads e and weft breakage will occur. .

In addition to the above-mentioned functions, the illustrated embodiment is constructed so that when the shuttle is fitted into the shuttle box, the weft thread will not be caught between the shuttle body and the shuttle box. There is. That is, in this embodiment, a shoulder portion 8 (its height is:
The thickness of the plate is the same as that of the shuttle box or slightly larger than that of the shuttle box plate. In this way, when the shuttle stops fitting into the shuttle box, the 6th
As shown in the figure, there was a risk that the weft yarn e would be caught between the shuttle body and the plate 9 and break, but according to this embodiment, the weft yarn d is Since the weft threads hang outward from the plate 9, it is possible to eliminate the risk of the weft thread being pinched as shown in FIG.

[Effect of idea]

As described above, according to the present invention, in the top drawer type induction shuttle, the weft threads are drawn out without being bent significantly, so that the weft threads can be drawn out smoothly, and the warp threads forming the shedding and the drawn weft threads can be drawn out smoothly. Since there is no sliding contact,
This has the effect of eliminating inconveniences such as thread breakage due to sliding contact with warp threads.
