Abstract

PURPOSE:To enable weaving of a triple or quadruple axis woven fabric with a simple construction by using a picking and reed beating devices, crossing forward and return oblique yarns fed from an oblique yarn creel in mutually opposite oblique directions, then converting the directions into nearly right angles and suitably opening the yarns. CONSTITUTION:An oblique yarn creel (A) having many split oblique yarn beams 5 is constituted so as to be rotatable in a circular rail 12 of a side frame 13 and then rotate in the horizontal plane and a weaving plane is also advanced in the horizontal plane. Many oblique yarns 3 and return oblique yarns 4, circulating and moving in the opposite directions at a prescribed interval are crossed in the mutually opposite oblique directions and the feed passages thereof are converted into nearly right angles. Oblique yarn heald guide needles 18 and 18 are held with a pair of left and right oblique yarn heald needle pressers 21 and 21 to suitably provide an opening in the above-mentioned forward and return oblique yarns 3 and 4. The weft yarns 2 are then folded in with a picking device (C) to advance weaving by operation of a reed beating device (D) and a woven fabric is wound by a product winder (E).

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is applicable to triaxial fabrics consisting of diagonal yarns and weft yarns in two directions that intersect with the bias direction, and in addition to triaxial fabrics consisting of diagonal yarns and weft yarns in two directions that intersect with the bias direction, and quadriaxial fabrics in which warp yarns orthogonal to the weft yarns are overlapped. This invention relates to a multi-shaft loom for weaving textiles.

<Prior Art and Problems to be Solved> Disclosures of three-shaft looms can be found in Japanese Patent Publication No. 59-348], No. 2, Japanese Patent Publication No. 36015-1987, etc. These three-shaft looms use two lines (directions) of intersecting diagonal threads as warp threads, open the forward and backward diagonal threads, and insert the weft threads into these threads to weave. The horizontal movement of the thread involves weaving diagonal threads across each other by moving the heddle device in the left-right direction, which has the disadvantage of skipping stitches and making it unsuitable for high-speed movement.

Regarding the four-shaft loom, 1. The present inventor has already published a patent application in JP-A-63
This method has been proposed in No. 92751 and Japanese Patent Application No. 62-207142. These four-shaft looms had separate diagonal thread traverse devices and diagonal heddle devices that traversed diagonal threads in two directions and supplied them to the woven surface.

According to the present invention, the diagonal thread 1 to the rubber device and the diagonal heddle device are...
The object of the present invention is to provide a multi-axis machine for three-axis or four-axis weaving, which has a cylindrical structure and is suitable for high-speed weaving. .

Effects and Examples> Hereinafter, the configuration of the present invention will be explained as follows.
This will be explained in detail.

FIG. 1 is a schematic side view of a multi-lll-lll loom of the present invention, and FIG. 2 is an enlarged side view 1118 of the main part. FIG. 3 is a bottom view of the guide chain member used in the traverse mechanism of the diagonal thread traverse heald device. Figures 4 to 8:3 are side views 111B for explaining the mechanism of a multi-shaft loom for four-shaft textiles in step-by-step weaving steps. FIG. 9 is a tissue diagram showing an example of a four-axis fabric woven by multi-axis aa according to the present invention.

The multi-shaft loom of the present invention shown in Fig. 1 is a loom for triaxial textiles, in which a large number of bobbins or a plurality of divided beams are arranged in a plane substantially parallel to the traveling direction of the woven surface so as to rotate at 0 J. It has a diagonal creel (Δ) in a circular arrangement. Diagonal creel (
8) has a large number of divided diagonal thread beads A (5), which are rotatably supported by the circular rails (12) of the side flaps l (13).

The symbol g(1/l) in FIG. 1 is the upper frame. The diagonal creel (A) rotates in a horizontal plane, and the woven surface also advances in a horizontal plane. This point is a major feature of the present invention, and in conventional looms, the rotating surface of the diagonal thread creel (A) and the traveling direction of the woven surface were approximately at right angles.

The diagonal I-rubber heddle device ((1) applies force continuously at predetermined intervals from the diagonal creel (A) substantially within the weaving plane.
In addition, a large number of reciprocating diagonal yarns (3) and reciprocating diagonal yarns (4) that circulate in opposite directions are fed across each other in opposite inclination directions, and these reciprocating diagonal yarns (3) ('l) Almost 90 supply routes
This is a device with an unprecedented structure that combines a diagonal thread traverse mechanism that converts and supplies the diagonal threads to the woven surface, and a diagonal thread heddle mechanism that opens the reciprocating diagonal threads (3) (/I). As shown in FIG. 3, a large number of needle guide holes (1,7) (1,7 A diagonal heddle guide button (18) is inserted into each of the

The shaft (19) of 15) is rotatably supported by a bearing (20), and this shaft (19) is driven intermittently.

Here, the movement of the diagonal heddle needle (18) is another major feature of the present invention. Because the weaving surface is a horizontal plane, the cam drive causes vertical reciprocation (r', 1-thread heddle presser (21) (2]) to move the left and right rows of diagonal heddles (F).
By holding down #l (IlO), the silk threads (3) (4) can be threaded back and forth once. -1- rise is due to the reaction force of the spring (11), for example.

As shown in Figure 1, either the reciprocating diagonal thread (3) or (4) is open 1.
When the weft thread (2) is pressed, the weft thread driving device ((',)
Enter. As is clear from FIGS. 4, 7, and 8, the supply path is extended from the tip of the diagonal heald guide from the approximately vertical direction to approximately 11 directions. The reciprocating diagonal yarns (3) and (4) that are converted and sent out to the woven surface are

At the tip of the diagonal thread (
The rear thread (thread (4)) sent out from the tip of the diagonal heddle guide 1 (]8) of 4) is arranged so as not to be damaged and circulate smoothly. The spacing of the heddle needles (1, 8) (1, 8) and the reciprocating diagonal thread (:(
)(4) becomes IIJ depending on the interaction with the inclination angle when being supplied to the woven surface. .

As the weft driving device (C), the reed driving device (1)), and the product winding device (14), conventionally known devices can be used as they are.
The weft (2) is run by the weft driving device (C), which is arranged sequentially from the left to the right in the figure, and the reed (8) is beaten by the reeds (8) (8) of the punching device (1). Then, the product is rolled into a product roll (9) by a product winding device (X).

The following explanation was about a multi-shaft loom for three-shaft textiles.

The mechanism of a multi-shaft loom for 4+1ll fabric incorporating Q is explained with reference to FIGS. 4 to 8.

As shown in Fig. 4, the warp (la) (1t+) is divided into two series and sent out from the diameter adjustment bead (1) and (6) provided to send the warp (1) in the same direction as the woven surface. is a warp heddle divided into many two series (]Oa) (1ot,)
As shown in FIGS. 7 and 8, the shedding is timely divided by the force 11 drive, and combined with the above-mentioned mechanism for triaxial fabrics, a four-axis fabric is produced.

The weaving structure of the four-axis fabric produced by this four-axis fabric loom is as shown in FIG. That is, the opening C1 of only the forward diagonal thread (3) in FIG. 5, the opening C1 of only the front warp thread (1a) in FIG. Fig. 8 shows the case where the rear warp (1b) only is opened once every four rotations in the order of opening L1, and the four types of yarns are sequentially opened four times - the turning weft (
2) is shown.

As described above, the multi-shaft loom of the present invention has the forward diagonal yarn (3), the reverse diagonal yarn (4), and the divided warp yarn (1). By changing the order, you can find the most suitable opening 1 for thick yarn, thin yarn, mixed yarn of thick yarn and silk yarn, or depending on the density and density of placing.
It is possible to select the order to create various textures, and it is possible to weave triaxial or quadriaxial fabrics of various textures at high speed.
