BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circular knitting machine that can change the shape of a sinker pin and a sinker cam, and also change the shape of a knitting cam in a circular knitting machine to woven a fabric having excellent shape stability.

Conventional fabrics are woven through a circular knitting machine comprising a sinker cam and a knitting cam that interlock the interacting sinker and the knitting needle, respectively. Such circular knitting machines can express various patterns such as stripes, squares or diamonds on the woven fabric by changing the knitting of the sinker cam or the knitting cam. Since the woven fabrics are excellent in heat retention and excellent in touch, they are widely used as sports clothes and T-shirts.

However, when expressing various patterns on the fabric by changing the knitting of the sinker cam or the knitting cam, the loop does not come out from the back of the woven fabric and the fabric was not flat, and furthermore, the durability of the fabric was poor.

In addition, the existing circular knitting machine has to use only the velours only and the loops have to be matched one by one, which required a lot of labor and work time.

The present invention has been made to solve the above problems, even if a variety of patterns on the woven fabric to express the loop does not come out of the surface of the fabric or the durability of the fabric provides a circular knitting machine that can improve productivity It aims to do it.

In order to achieve the above object, the circular knitting machine for a fabric according to the present invention, a cylindrical ring chain cylinder that rotates in a horizontal plane around a central position and provides a moving passage of a plurality of knitting needles 5 in the vertical direction ( 10); A knitting cam box 20 for raising and lowering the knitting needle 5 by forming a passage in which a butt 5a of the knitting needle 5 is fitted as being fixed in a ring shape on the outer circumferential side of the cylinder 10; A dial 30 disposed at an outermost periphery of the cylinder 10 and rotatably driven together with the cylinder 10 and having a plurality of dial grooves formed in the knitting direction; A plurality of sinkers 40 installed in the dial groove; A sinker ring (50) positioned above the dial (30); A plurality of sinker cams 60 installed on the sinker ring 50 for advancing and sinking the sinker 40 toward the knitting needle 5; And an upper subsidiary sinker cam 65a and a lower subsidiary body disposed between the sinker cam 60 and another sinker cam 60 'with a passage D ′ through which the sink cover 41 of the sinker passes. It characterized in that it comprises a ;; the auxiliary sinker cam (65) in a pair of configurations consisting of a sinker cam (65b).

Hereinafter, with reference to the accompanying drawings, a circular knitting machine for woven fabrics according to the present invention will be described in detail.

Figure 1 is a side cross-sectional view showing the main configuration of the circular knitting machine for the fabric according to the invention, Figure 2 is a view showing the knitted cam box of Figure 1, Figure 3 is a view showing an extract of the sinker of Figure 1 4 is a view showing the positional relationship between the sinker cam and the auxiliary sinker cam of FIG.

As shown, the circular knitting machine for a fabric according to the present invention includes a cylindrical ring chain cylinder 10 which rotates in a horizontal plane about a central position and provides a moving passage of several knitting needles 5 in a vertical direction; A knitting cam box 20 which raises and lowers the knitting needle 5 by forming a passage in which the butt 5a of the knitting needle 5 is fitted and fixed in a ring shape on the outer circumferential side of the cylinder 10; A dial 30 disposed on an uppermost outer circumferential side of the cylinder 10 and rotatably driven together with the cylinder 10 and having a plurality of dial grooves formed in the knitting direction; A plurality of sinkers 40 installed in the dial groove; A sinker ring 50 located above the dial 30; It is installed in the sinker ring 50, a plurality of sinker cam 60 for advancing and sinking the sinker 40 to the side of the needle (5).

The knitting cam box 20 is arranged in a ring shape on the outer circumferential side of the cylinder 10, and a plurality of knitting cams are arranged at regular intervals. As the knitting cam, the knit cam 21, the stitch cam 22, and the like are separately installed according to a desired pattern, and the butt 5a of the knitting needle is installed below each of the knit cam 21 and the stitch cam 22. Corresponding knit cam 23 and corresponding stitch cam 24, which form a knitting cam passage D, to which the movement moves, are separately installed. These knitting cams 21, 22, 23, 24 are mounted in a slot (not shown) formed in the longitudinal direction in the knitting cam box. By this structure, the butt 5a of the knitting needle 5, which is rotated together with the cylinder 10, moves along the knitting cam passage D of the fixed knitting cam box, and as a result, the knitting needle 5 moves to the cylinder 10. To the top of the

At this time, at the end of the passage formed between the stitch cam 22 and the corresponding stitch cam 24, the butt 5a of the knitting needle 5 gently enters the passage between the knit cam 21 and the corresponding knit cam 23. A slightly raised entry step D1 is formed to allow entry. By forming such entry step D1, when the butt 5a enters the passage between the knit cam 21 and the corresponding knit cam 23 from the passage between the stitch cam 22 and the corresponding stitch cam 24. It is possible to prevent the vibration from occurring, thereby preventing the phenomenon of shrinking in the woven fabric.

The sinker 40 is integral with the sinker body 40a and the sinker body 40a in which the sinker cover 41 is formed by being in contact with one side 60a of the sinker cam 60, and latches the knitting needle 5. The sinker head 40b is formed with a nose 42 deviating therefrom.

At the corners of the sinker head 40b in contact with the sinker body 40a, a dust barrier 40c is formed to prevent dust from being caught between the sinkers 40 that rotate at high speed together with the dial 30. By forming the dust prevention jaw 40c, it is possible to minimize a lot of dust generated during weaving between the sinkers, thereby enabling the operation of the circular knitting machine for a long time.

It is preferable that a nose inclined surface 42a is formed at the upper end of the nose 42 of the sinker 40 so that the yarn caught on the latch of the knitting needle 5 can be easily pulled out. By forming the nose inclined surface 42a, it is possible to prevent the tread phenomenon (a phenomenon in which long and short loops are generated due to the elasticity of the yarns) in which the loops protrude long regardless of which yarn is used.

The sinker cam 60 is repeatedly installed to form a circumference in the sinker ring 50. At this time, between the sinker cam 60 and the other sinker cam 60 ', the auxiliary sinker cam 65 for returning the sink cover 41 to one side 60a, 60a' of the sinker cam 60 is provided. Is installed.

The auxiliary sinker cam 65 has a configuration consisting of an upper auxiliary sinker cam 65a and a lower auxiliary sinker cam 65b with a passage D ′ through which the sink cover 41 passes. The sinker 40 moves forward and backward in the direction of the knitting needle 5 as the sink cover 41 rotates while being in contact with the sinker cam 60 and the auxiliary sinker cam 65. The auxiliary sinker cam 65 is installed in the long hole 51 formed in the sinker ring 50, and can move a predetermined interval within the long hole 51, it is also possible to adjust the retreat distance of the sinker 40.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.

As described above, according to the annular knitting machine for the present invention, at the end of the passage formed between the stitch cam and the corresponding stitch cam, so that the butt of the knitting needle enters the passage between the knit cam and the corresponding knit cam to enter smoothly. Since the slightly raised entry jaw D1 is formed, it is possible to prevent the occurrence of vibration during entry, thereby preventing the phenomenon of shrinking to the woven fabric.

In addition, a dust barrier is formed at the corners of the sinker head in contact with the sinker body to prevent dust from being caught between the sinkers rotated at high speed with the dial, thereby minimizing the occurrence of a lot of dust generated during weaving between the sinkers. It is thereby possible to operate the circular knitting machine for a long time.

In addition, a nose slope is formed on the top of the nose of the sinker to easily pull out the yarn hooked by the latch of the needle, thereby preventing the tread phenomenon that the loop is protruded to the surface of the woven fabric no matter what yarn is used. can do.

And forming a long hole in the sinker ring, and having an auxiliary structure consisting of an upper secondary sinker cam and a lower secondary sinker cam between the one sinker cam and the next sinker cam, with a passage (D ') through which the sink cover passes. By installing the sinker cam in the long hole, anyone can easily install the auxiliary sinker cam, and furthermore, there is an effect that the sinker retreat distance can be adjusted.

As a result, the above configurations can not only express various patterns on the woven fabric, but also prevent the loops from escaping to the surface of the fabric or the durability of the fabric, and greatly reduce work time and effort, and add high value. Will maximize the production efficiency of the fabric.
