The present invention relates to a sock knitting machine for knitting an out pile pattern, and more specifically, a sock which enables the knitting of a pile pattern at a high speed, and also prevents the inside thread soak phenomenon caused by the inside of the yarn and the outer thread. The present invention relates to an out-file high speed knitting apparatus of a knitting machine.

In general, the hosiery knitting machine is a knitting needle installed upright along the circumferential direction of the cylinder, a sinker installed between the knitting needle to move back and forth in the transverse direction of the cylinder, and moves the sinker forward and backward as the cylinder rotates. A sinker cam and a single needle cam for moving the single needle in the vertical direction as the cylinder rotates.

The hosiery knitting machine is a device for automatically knitting the hosiery. When the principle of operation is described, a plurality of needles arranged along the circumferential direction of the hoisting cylinder move up and down during rotation and hang on the sinker. Knitting is achieved by pulling down the thread that is present. In this case, about 200 needles are arranged to move up and down along the inner diameter of the cylinder, and a similar number of sinkers are disposed between the needles so as to be movable back and forth in a direction perpendicular to the needle.

On the other hand, in recent years, to improve the quality of the socks, the socks selected by the actuator (actuator) automatically controlled according to the input program of the computer advances the outsole pattern knitting socks to form a pile pattern on the socks by moving forward than when knitting A knitting machine was presented. In the sock knitting machine for knitting an outpile pattern, it is important to keep pushing forward the sinker, which is rotated by an actuator during knitting of the pile pattern, until the knitting decision can be made to uniformly knit good pile pattern at high speed.

However, the conventional outpile pattern knitting sock knitting machine is a sinker that rotates in the state advanced by the actuator when knitting the pile pattern because the sinker is pushed back by the centrifugal force at the moment when the protrusion of the sinker leaves the finger of the actuator. Since it does not maintain its advanced state until the knitting decision, it falls back by centrifugal force, so when knitting pile pattern on socks structurally, low-speed knitting is possible to some extent, but it is not possible to knit socks at high speed, which greatly reduces productivity. There was a problem, when the sinker is pushed back by the centrifugal force during the knitting of the pile pattern as described above, there was a problem in that a uniform pile pattern could not be formed because the hairs were removed and the pile was not formed.

Also, in the conventional outpile pattern knitting sock knitting machine, as described above, when the pile pattern is knitted, the sinker is pushed back by the centrifugal force, so when the sinker is pulled back, the inner thread and the outer thread are reversed and changed each other. This is different, and as a result, there was a problem that the sock loom occurs resulting in a drop in the quality of the socks.

Recently, in order to solve the above problems, it has been sought to extend the finger length of the actuator to push the sinker until the knitting decision is made when the pile pattern is knitted. In addition, when the finger length is long, it is a problem that cannot be realized because the high-speed knitting cannot be performed.

The object of the present invention is to solve the above-mentioned drawbacks, and to improve the structure so that the sinker does not fall back until the decision of knitting when knitting pile patterns, it is possible to knit at high speed, and knitting of pile patterns It is to provide an out-file high-speed knitting device of a sock knitting machine that can prevent the inner thread shinning phenomenon that the color changes due to the change of the inner thread and the outer thread.

In order to achieve the above object, the present invention is to install an actuator for advancing the selected sinker on the one side of the sinker cover forward than the plain weave knitting, but the sinker cover is extended from the finger front end of the actuator to the knitting decision portion The guide cam is installed, and the rear upper portion of the sinker is formed with a rolling preventing protrusion that is caught by the guide cam when the pile pattern is knitted, so that the sinker is not pushed back until the knitting decision is made.

Hereinafter, the technical configuration of the present invention in detail according to the accompanying drawings.
