Description

  The present invention relates to a torsion lace machine that can be easily knitted as a flat lace.

  Generally, a torsion lace machine is driven while rotating a spindle runner and a bobbin by the rotation of a rotor metal arranged in a perfect circle on a plane. A product is formed, crushed flat, and wound around a winding drum through a pinching roller (see JP-A-9-111626). The cylindrical product wound around the winding drum usually uses a thread at one place on the circumference, and pulls the thread and unfolds it flatly for various uses (for example, skirts for women's clothing, Used for collar decorations).

Using the above torsion lace machine, flattened carbon fiber yarns are wound around a bobbin, and the carbon fiber yarns drawn from the bobbin are gathered in the center to form a plain weave shape in the bias direction. (See Japanese Patent Publication No. 51-36826) By inserting warp, there is an advantage that an industrial composite material exhibiting non-deformation force in the machine direction and the bias direction can be easily produced.
JP-A-9-111626 Japanese Patent Publication No.51-36826

However, carbon fiber yarns exhibit extremely high strength in the pulling direction, but are fragile to breakage, and as described above, a tubular product knitted into a tubular shape is flattened using a torsion lace machine. In addition to the problem that the carbon fiber yarn breaks and becomes brittle when it is hung on a narrow pressure roller, a thread is used at one place on the circumference of the cylindrical product, and the flat product is pulled out. When deployed as a (single piece), it is flat from the circumference, the amount of development is large, and undulation (light bow-shaped curve) occurs in the carbon fiber yarn that runs in the bias direction, so it extends by that undulation ( There was also a problem that non-deformation force was reduced.

The present invention is intended to solve the above problems, and the object of the present invention is to prevent the carbon fiber yarns arranged in a flat shape from breaking, and to run in the bias direction even when flattened. The “swell” as described above does not occur in the yarn, and a torsion lace place (industrial composite material product) free from the problem of elongation is obtained.

In order to achieve the above-described object, the present invention provides a carbon fiber yarn unwound from a bobbin supported by each spindle runner that has a rotor metal arranged in a plane semicircle and is driven by the rotor metal on the arc. It is characterized in that it is supplied to a beating portion in the center of a metal arc, and is not folded to make it flat from a non-cylindrical shape, so that the amount of development is small.

According to the present invention, the rotor metal in the torsion lace machine is characterized by being arranged in a plane end circle, so that the knitted race does not become cylindrical from the intended state, and when it is wound around the winding drum, the narrow pressure roller In addition to not being flattened by the carbon fiber yarn , not only does the strength decrease due to the breakage of the carbon fiber yarn , but the amount of development is small unlike the development from the cylinder, and thus the carbon fiber yarn is undulated. There are various excellent effects such as that the strength is not reduced.

  Next, embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a partially cutaway plan view of the present torsion race machine, FIG. 2 is a left side view of the present torsion race machine, FIG. 3 is a front view of the present torsion race machine, and FIG. 4 is a portion showing the arrangement of the rotor metal and spindle runner. FIG. 5 is a side sectional view showing a bobbin mounted on a spindle runner and a vertical insertion device, and FIG. 6 is a partial development view of a product knitted by the torsion lace machine of the present application.

In FIG. 1, reference numeral 1 denotes a torsion race machine of the present application. In the torsion lace machine 1 of the present application, the rotor metals 2, 2. The plane end circle is not a perfect circle like a plane semicircle, but a circle with an end, and may be 1/3 circle or 1/4 circle. Shows a circle.

  As can be seen from FIG. 4, the rotor metal 2 has arc concave portions 2a and 2a at opposing positions and arc convex portions 2b and 2b at orthogonal positions. In the arc-shaped continuous groove 3 ″ between the plate 3 and the outer guide plate 3 ′, arc concave portions are arranged so as to face each other, and are linked to the drive unit 4 so as to rotate right or left on the spot.

  The rotor metal 2 rotates to the right or left every 180 ° in the opposing circular arc recesses of the rotor metal 2 on the left and right sides thereof, and stops accurately. Therefore, the rotor metal located at symbol A in FIG. When the (striped line) 2 turns in the direction of the arrow (right) in the arc surrounded by the circular arc recesses of the rotor metals 2 and 2 positioned at B and C, the spindle runner between A and B 5 is sent in the right direction, and the spindle runners 5 between A and C are sent in the left direction to exchange their positions.

  By the action of the rotor metal 2, the yarn 8 unwound from the bobbin 7 fitted to the bobbin shaft 6 mounted on each spindle runner 5 is drawn out as shown by a one-dot chain line in FIG. 3 and gathered at the center portion 9 of the torsion lace machine 1 of the present application, and beaten by a beating portion 10 provided with a lead knife, and in a plain weave shape in the bias direction as a non-cylindrical product (planar semicircle). Be organized. As a result, the torsion race ground 11 is obtained as shown in FIG.

  The drive unit 4 is configured as shown in FIG. That is, a drive gear 43 that drives a clutch 42 loosely fitted in a hollow shaft rod 41 that passes through the axis of the rotor metal 2 is provided. The rotation of the drive gear 43 is linked to another drive source not shown in the figure. The clutch 42 moves up and down by the action of the shifter 44, transmits the rotation of the drive gear 43 to the rotor metal 2 when moving up, and releases the connection with the drive gear 43 when moving down.

  A warp thread 12 is inserted into the torsion lace 11 as shown in FIG. The warp yarn 12 is inserted into the structure of the torsion race 11 from the upper end of the cylindrical body 14 drawn from the bobbin 13 installed under the machine body 1 ′ and extending from the upper part of the hollow shaft 41 of the rotor metal 2. enter. In other words, the torsion lace place 11 knitted by the present torsion lace machine 1 has a non-deformable force in the longitudinal direction and the bias direction by the yarn 8 knitted in the bias direction and the warp yarn 12 inserted into the structure. It can be made as an industrial composite material product showing.

  In the torsion lace machine 1 of the present application, as described above, the rotor metal 2 is arranged in a semicircular plane, so that an empty space S is formed outside the straight line 16 connecting both end portions 15 and 15 '. Therefore, the yagura 17 can be assembled in this empty space S as shown in FIGS. The yagura 17 is provided with stairs 18 from the left and right sides so that an operator (operator) can climb, and repair and adjustment work of various facilities (mechanisms) provided in the central portion 9 of the torsion race machine 1 of the present application. Can be performed directly by the operator.

  In the torsion lace machine 1 of the present application, the torsion race ground 11 is not knitted in a cylindrical shape, but is always knitted as a semicircular product. The semicircular product is flattened and wound around a winding drum (not shown) through the pinching roller 19. Therefore, unlike a cylindrical product, it does not crush flat, so even if carbon fiber yarn is used, there is no attenuation of strength due to “breaking”, and a punched yarn used at one place on the circumference of the cylindrical product Compared to pulling out and developing flat products, the expansion rate is small and there is no “swell”.

  Although the torsion race machine of the present application in which the rotor metal 2 is arranged in a plane end circle has not been described in detail, each rotor metal 2 can freely rotate in the right direction and the left direction, and a desired spindle runner It is also possible to carry the (bobbin) to the target position several steps ahead without being entangled with other yarns.

The present invention is a torsion lace machine in which flat carbon fiber yarns are formed in a flat weave shape in the bias direction, and can be placed vertically at the same time, and the rotor metal has a planar end circle (mainly a planar surface). By making it possible to create a non-circular knitted product by placing it in a semi-circle), it is possible to directly perform repair work and adjustment work at the center where yarn is concentrated by the operator's hand by forming a yagra in the empty space In the torsion racing industry, it can be said that the applicability is high.
