Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an apparatus for producing a double-knitted fabric that can be formed with separate textures on the front and back sides, which is capable of forming a three-dimensional pattern on the knitted fabric.

[Conventional technology]

Conventionally, this type of device braids the outer material with a cylinder and a cylinder needle, separately braids the lining with a dial and dial needle, and simultaneously braids the outer material and the lining with the needles crossed so that the outer material and the lining are integrated. I try to knit it.

[Problem to be solved by the invention]

By the way, the patterns of the knitted fabric knitted by such devices are mainly flat patterns (there was a problem that it was difficult to create three-dimensional patterns and patterns. When braiding a pattern or pattern, if you operate only the cylinder needle that weaves the pattern while the cylinder needle or dial needle in the part that does not form the pattern is inactive, a bulge will be formed on the outer fabric of the pattern. However, at this time, even though the patterned part is braided, other parts are not braided, so the knitted fabric suspended from this part is gradually stretched. This causes the knitted fabric in the patterned part to lose tension and hinder braiding.The present invention was proposed in view of the above problems, and uses a simple device to create a three-dimensional pattern with a large bulge on the outer material. The purpose is to enable the pattern to be reliably braided.

[Means to solve the problem]

In order to achieve the above object, the method for producing a three-dimensional pattern on a double knitted fabric according to the present invention is a double knitted fabric in which the outer material is roughly knitted with a cylinder and a cylinder needle, and the lining is knitted almost simultaneously with a dial and a dial needle. In the manufacturing method, the sinker is driven forward and backward in conjunction with the three-dimensional pattern braid formed on the outer material and/or the lining, and the three-dimensional pattern knitted fabric portion is pressed by the tip of the sinker. The apparatus for producing a three-dimensional pattern on a double knitted fabric according to the present invention is characterized in that tension is applied, and the apparatus includes a cylinder, a cylinder needle, a dial, and a dial needle. A sinker that advances and retreats in conjunction with the three-dimensional pattern braid formed on the outer material or the lining is arranged so that when the tip of the sinker advances, it presses the braided three-dimensional pattern knitted fabric part. It is something.

[Effect]

When the outer material is braided with the cylinder and the cylinder needle and the lining is braided with the dial and the dial needle, the outer material and the lining are integrally braided by crossing the cylinder needle and the dial needle. For example, when forming a bulging three-dimensional pattern on the outer material, the cylinder needle of the pattern part is operated while the cylinder needle and dial needle of the pattern part are operated to form the bulge on the outer material. At this time, the knitting fabric tension applied to the cylinder knittle and dial needles other than the patterns that are at rest is applied, and the tension gradually disappears in the pattern part to be knitted with the cylinder knittle needle, making it difficult to knit. The tip of the sinker presses down and applies appropriate tension to the tissue formed by the cylinder needle in the pattern area, allowing for good braiding, forming a predetermined bulge, and braiding a three-dimensional pattern. . Note that even when a three-dimensional pattern is formed on the lining material or the lining material in addition to the outer material, the desired pattern can be formed by providing a sinker that operates in the same manner as described above.

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 shows a perspective view of the main parts of a double knit machine that can knit the outer material and the lining material at the same time. This double knitting machine 1 consists of a cylinder 2, a cylinder needle 4 that is guided by the cylinder 2 and slid up and down from a cam I to braid the outer material, and a dial 5.
and a dial needle (knitting fabric needle) 7 that is guided by the dial 5 and slid up and down by a cam 6 to braid the lining, and a gap 8 for passing the knitted fabric is opened at the tip thereof, so that they intersect at approximately right angles. and cylinder needle 4.
A sinker 9 is disposed near the tip of the sinker 9, and the sinker 9 is driven by a drive cam 10 (see FIGS. 2 to 5) that is linked to the vertical movement of the cylinder needle 4 so that the tip of the sinker 9 is inserted into the gap for passing the knitted fabric. 8 and a standby position 12 that exits from the knitted fabric passage gap 8. In addition, the reference numeral 13 in the figure is a thread path for supplying the thread 14 to the cylinder needle 4 and the dial needle 7. The operation of the double knitting machine 1 configured as described above will be explained next. In the case of a plain color or a flat pattern, as shown in FIGS. 2 and 3, the cylinder needle 4 and the dial needle are applied with tension W applied to the knitted fabric 15 in the knitted fabric passing gap 8 using a weight or the like. The thread 14 is supplied to the thread 7 and the thread 14 is driven forward and backward. Then, as in the conventional double knitting machine 1, the outer material of the yarn 14 supplied from the yarn path 13 is braided by the cylinder 2 and the cylinder needle 4, and at the same time, the lining material is integrated with the outer material by the dial 5 and the dial needle 7. It is woven in a specific manner. At this time, the sinker 9 is interlocked with the cylinder needle 4 by the driving cam lO, and its tip is at the operating position 11 and the standby position 1.
2, the knitted fabric 15 in the knitted fabric passing gap 8 is pulled downward mainly by the tension W of a weight or the like. Next, when forming a three-dimensional pattern with partial bulges on the outer material, the cylinder needle 4 that forms the outer material other than the swollen three-dimensional pattern and the dial needle 7 that forms the lining are paused. As shown in Figure 4, the drive cam 10 advances the sinker 9 to a state where its tip comes into contact with the knitted fabric 15 in the knitted fabric passage gap 8 to apply tension to the loop 16 hooked to the cylinder needle 4. do. Next, move the cylinder needle 4 that organizes the swelling pattern upward (
Raise it in the direction of arrow A) and hook 4a of cylinder needle 4.
After supplying the yarn 14 to the cylinder needle 4, as shown in FIG. 5, when the cylinder needle 4 is lowered, the number of loops 16 in the cylinder needle 4 will be greater than in the resting part, and a bulge will be formed accordingly. . At this time, the tension W of the weight, etc., which had been acting on the knitted fabric 15 in the knitted fabric passage gap 8 until now, is suspended on the dial needle 7 and the cylinder needle 4 other than the cylinder needle 4. Although it no longer acts on the loops 16 of the cylinder needle 4 that form the pattern, the tip of the sinker 9 that has advanced into the knitted fabric passage gap 8 comes into contact with the loops 16 in the pattern area and applies tension. It is possible to perform good braiding, form a predetermined bulge, and braid three-dimensional patterns. Incidentally, in the above embodiment, the sinker is driven all the time, but the point is that the sinker may be provided for the knitting fabric needle in the part where the three-dimensional pattern is to be weaved. Furthermore, in the above embodiment, the case where a three-dimensional pattern is formed on the outer material is explained as an example, but when a three-dimensional pattern is formed on the lining in addition to the lining and the outer material, the three-dimensional pattern is formed. The sinker of the above embodiment may be provided on the side knitting fabric needle.

【Effect of the invention】

As explained above, the method and apparatus for producing a three-dimensional pattern on a double knitted fabric according to the present invention, when braiding a large three-dimensional pattern or pattern on the outer material or lining portion, uses sinkers to form at least the pattern. The sinker moves forward and backward in conjunction with the knitting needle in the section, and the tip of the sinker suppresses the structure of the three-dimensional pattern or pattern section to be braided, giving tension, so that good braiding can be performed. By forming a predetermined bulge, a three-dimensional pattern can be braided. This has the advantage that large, bulging three-dimensional patterns and patterns can be reliably and easily braided. In addition, a simple device is required that moves the sinker forward and backward in conjunction with the knitting fabric needle at least in the part where the pattern is knitted, and the tip of the sinker suppresses the tissue in the pattern part, and it can be implemented at low cost. , it has the advantage that it can be easily implemented even in existing systems.
