Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sinker pile patterning device for socks, tights and similar products in a circular knitting single machine.

[0002]

Pile knitting in a single sock knitting machine is
It is general that the inner surface of the knitted fabric is entirely pile-knitted, or the pile knitted fabric is partially formed on the bottom or the instep. Conventionally, when forming such a pile knitted fabric, an operation cam (pile cam) in which a pile sinker having two noses including a sinker nose and a pile nose above the sinker nose is swingably provided on a part of the sinker cam. ), The pile yarn was placed on the pile nose to form pile eyes. But,
With the action of the actuating cam, it is impossible to finely change the normal stitches and the pile stitches, and it is not possible to arbitrarily perform patterning.

Therefore, Japanese Patent Publication No. 61-53452 and Japanese Patent Publication No. 63-3839 disclose a slit 41 for a needle 42 of a needle cylinder 41 as shown in FIGS. 4 and 5.
A slit 41b for the sinker selector jack 43 is provided between a, and the sinker selector jack 43 is arbitrarily selected by the actuator 44 and the sinker selector jack 43 is raised to form an inclined surface at the upper end of the sinker selector jack 43. There is disclosed a method of advancing the pile sinker 45 that is in contact with the pile sinker 45 to perform pile patterning.

However, in carrying out the above-mentioned patterning method, the slits 41a, 41 of the needle cylinder 41 are formed.
Since b has to be cut twice as many as the number of needles, there is a limit to the number of needles of the circular knitting machine that can be manufactured. Further, as for the number of stages of the selector butt, half the number of stages can be used for the handle because the sinker selector jack 43 and the needle selector jack 46 are used for the general handle pattern. Further, in order to secure the strength of the sinker selector jack 43, it is necessary to make the depth of the slit 41b for the sinker selector jack 43 deeper than that of the slit 41a for the needle 42.
There was a problem that the cylinder manufacturing process became complicated.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention has a simple structure by directly controlling a sinker and uses the same cylinder as a general circular knitting machine and the same number of stitches. An object of the present invention is to provide a sinker pile patterning device for a circular knitting machine, which is capable of arbitrarily performing pile patterning while securing the number of patterns.

[0006]

Means for Solving the Problems A circular knitting single machine is provided with a sinker sorting bat having a plurality of stages at the rear end of a pile forming sinker, and the sinker is pressed directly against the bat to form pile stitches. An operating portion of a sinker selecting actuator that reciprocates between an operating position and an inactive position is provided for each stage.

[0007]

When the actuator is actuated and the actuating portion (finger) is positioned at the actuating position, the sinker selecting butt comes into contact with the actuating portion and the sinker is pushed in, and the pile yarn is glued to the pile nose of the sinker. Eyes are formed. When the operating portion is retracted from the working position, the sinker only performs a normal operation by the sinker cam, and the pile yarn is knitted together with the ground yarn on the lower surface of the sinker nose to form a normal stitch. .

The sinker selecting bat is provided in a plurality of stages at the rear end of the sinker, and an actuator can be operated between adjacent sinker selecting bats. Therefore, an arbitrary pile pattern can be knitted by controlling the actuator. It

Sinker bed 22 having a slit 21 in the same phase as
Is fitted and fixed by a clamp 23, and a pile sinker 24 is inserted into the slits 18 and 21.

The pile sinker 24 is a sinker nose 2
4a and a pile nose 24b above the two noses. 24c is a sinker cap 25
Sinker cam 26 and inner cam 27 fixed to the lower surface of the
It is a sinker butt that engages with a groove 28 formed between and. Further, in order to perform pile patterning by the patterning device 1 at the rear end portion of the pile sinker 24, in the example shown in the figure, the selector bats 2 for selecting sinkers are arranged in upper, middle and lower three stages.
9 (29A, 29B, 29C) are provided and one arbitrary place is projected.

The sinker pile patterning device 1 controls a sinker selecting actuator 31 having three upper and lower fingers 30 (30A, 30B, 30C) corresponding to the selector butt 29, and the actuator 31. It comprises a control means (not shown) such as a computer. As shown in FIG. 2, the finger 30 (30A) is provided so as to be capable of swinging up and down about a shaft 30s at the base end, and is attached to a corresponding selector butt 29 (29A) of the pile sinker 24 by a command from the control means. The contact position (solid line position in FIG. 2) and the selector butt 29 (29A)
It is located at one of the non-acting positions (the position indicated by the chain double-dashed line in FIG. 2) that does not come into contact with and reciprocates between the two positions.
It should be noted that the selector butt 29 is used by leaving only one step so that the adjacent pile sinkers are out of phase with each other and breaking the others, and the finger 30 corresponding to the remaining selector bat 29 (29A in FIG. 2) is used. (30A in Fig. 2)
Is designed to work. And the finger 3
0 is a left sinker cam 2 as shown in FIG. 3 which is a plan view.
6a, the tip of the finger 30 forms a slanted guide edge 30e like the left sinker cam 26a.

Next, the operation will be described based on an embodiment.
In the following description, for convenience, the case where the uppermost selector butt 29A and the corresponding finger 30A shown in FIG. 2 are used will be described, and the description of other steps will be omitted as they follow.

The needle 10 that has reached the knitting position by the rotation of the needle cylinder 3 is pushed up by the needle butt 10b coming into contact with the rising cam 14 to knock over the old loop, and then the center cam (not shown). Before being pushed down by, the pile yarn P and the ground yarn G are supplied to the inside of the hook with the latch opened. At this time, the sinker 24 is pulled out by the inner cam 27.

In such a state, when the finger 30A of the actuator 31 is in the operating position, the pile sinker 24 is pressed when the needle 10 is further pushed down by the stitch cam (not shown) and the two yarns are knitted.
Is pushed inward by the selector butt 29A provided at the rear end of the pile sinker 24 coming into contact with the finger 30A and being guided by the guide edge 30e.
As a result, of the two supplied yarns, the ground yarn G is laid on the sinker nose 24a of the pile sinker 24 to form a normal short sinker loop, but the pile yarn P is laid on the pile nose 24b above the sinker nose 24a. , Becomes a longer sinker loop, and piles are formed.

The fingers 30 of the actuator 31 are also provided.
When A is in the inoperative position indicated by the chain double-dashed line in FIG. 2, the selector butt 29A does not abut the finger 30A and the pile sinker 24 is not pushed inward at that position. Both P and the ground yarn G are laid on the sinker nose lower surface 24d to form a normal stitch.

By appropriately selecting and performing these operations, an arbitrary pile pattern is knitted. In particular, in the patterning device 1 described above, the actuator 31 has three stages of fingers 30.
A, 30B, 30C are provided and pile sinker 2
3-stage selector butt 29A, 29B, 29 according to 4
Since C is provided, it is possible to freely change the action / inaction between the pile sinkers 24 adjacent to each other, and it is possible to perform pile patterning with a high degree of freedom. Further, since the action / non-action of the finger 30 is changed instantaneously by a slight swinging of the finger 30 in the vertical direction, it is possible to operate at high speed even with a relatively small number of stages. In relation to the number of stitches, finger 30 and
Of course, the number of stages of the selector butt 29 can be arbitrarily changed.

Further, the selector butt 29 is provided at the rear end of the pile sinker 24, and the selector butt 29 is guided by the obliquely inclined guide edge 30e of the finger 30 to directly push the pile sinker 24. The sliding of 24 is suitable for high-speed operation, and since the structure and operation are simple, adjustment and operation can be easily performed.

It is also necessary to use a relatively long sinker selector jack 43 as in the patterning device shown in FIGS. 4 and 5 described in the conventional example, or to cut the slit of the needle cylinder 41 by twice the number of needles. Instead, a commonly used cylinder can be used as it is, and the number of needles and the number of steps that can be used for needle pattern production can be the same as those of conventionally produced circular knitting machines.

[0021]

As described above, the sinker pile patterning device of the circular knitting machine of the present invention is provided with a plurality of sinker selecting bats at the rear end of the pile forming sinker of the circular knitting single machine, and Same as a general circular knitting machine, because each stage has an operating part of a sinker selection actuator that reciprocates between an operating position and a non-operating position where a sinker is directly pressed against the butt to form a pile stitch. By using the cylinder, it is possible to freely perform pile patterning while ensuring the same number of stitches and number of patterns. Further, the structure and operation are simple, adjustment and operation can be easily performed, and the manufacturing cost can be reduced.
