Description

  The present invention relates to a pile sinker device for a circular knitting machine capable of knitting a dense pile knitted fabric in which pile loops having different heights are formed in the same wale.

  For example, when a pile knitted sock is knitted in a sock knitting machine, the pile knitted sock is knitted by the cooperative action of a knitting needle that moves up and down a knitting needle cylinder and a pile sinker device that moves an annular sinker ring in a radial direction.

  An example of a conventional pile sinker device is shown in FIG. A pile sinker device 1 shown in FIG. 13 has a tip bifurcated portion 2, an intermediate portion 4 provided with a pile loop claw 3, and a rear end portion 6 provided with a bat 5. The tip portion 2 and the intermediate portion 4 is formed so that a pile thread sinker throat 8 is formed on the leading end side of the plating small claw 7, and the plating sinker throat is formed on the rear end side of the plating small claw 7. 9 is formed.

  As shown in FIG. 14, the pile sinker device 1 is moved forward in the direction of arrow A by a press cam (not shown), so that the tip portion enters between the knitting needles 10 and 10 moving up and down the groove of the knitting needle cylinder. The core yarn 11 is hung on the sinker throat 9, the pile yarn 12 is placed on the pile loop claw 3, and the pile knitted fabric by the core yarn 11 and the pile yarn 12 is knitted by the knitting needle 10 which moves down the knitting needle cylinder.

  However, when a pile knitted fabric is knitted using a sock knitting machine incorporating a pile sinker device, the pile length formed on the pile knitted fabric is equal to that of the pile loop claw 3 on which the pile yarn 12 of the pile sinker device 1 rides. Determined by position. That is, since the pile of the pile knitted fabric is determined by the pile sinker device and the knitting needle corresponding to the pile sinker device, the pile length of the pile knitted fabric is the same in the same wale.

  Conventional pile sinker devices can be knitted with pile piles with different heights on different wales by arranging different types of pile sinker devices on the ring sinker ring. Since the piles to be formed have the same length in the same wale, the pile knitted fabric to be knitted is greatly restricted, and a pile knitted fabric that is functionally satisfactory cannot be knitted.

In order to solve the above problems, as shown in FIG. 15, two sinkers 20 and 21 having different heights of the sinker claws 20a and 21a are arranged in parallel in the same groove of the annular sinker ring, and the two sinkers 20 , 21 is selectively operated by a sinker selective driving device, and a pile sinker device 22 has been developed that forms two piles having different heights on the same wale of a pile knitted fabric (for example, Patent Document 1). ).
Utility Model Registration No. 3037207 (see paragraph 0015 and FIG. 3)

  In the above pile sinker device, two sinkers having different heights are arranged in parallel in the same groove of the annular sinker ring, so that the groove of the annular sinker ring needs to have a width corresponding to the thickness of two stacked sinkers. There are limits to increasing the number of grooves in the annular sinker ring, that is, narrowing the groove pitch, and the number of grooves in the annular sinker ring and the number of grooves in the knitting needle cylinder correspond, so the number of knitting needles in the knitting needle cylinder, that is, the knitting needles Narrow gauges are limited, and it is impossible to knit a dense pile knitted fabric in which pile loops having different heights are formed in the same wale.

  The present invention has been made in consideration of the above points, and since the thickness of the pile sinker device can be set narrower than the conventional pile sinker device, pile piles having different heights are formed in the same wal. An object of the present invention is to provide a pile sinker device for a circular knitting machine capable of knitting a knitted fabric.

  The pile sinker device of the circular knitting machine of the present invention is formed by dividing a pile sinker into an upper pile sinker and a lower pile sinker provided with pile loop claws, and the upper pile sinker is formed on a vertical surface via a hinge means. The upper pile sinker is supported by the lower pile sinker so that the upper pile sinker can swing.

  The pile sinker device of the circular knitting machine of the present invention is configured such that the upper pile sinker provided with the pile loop pawl is swingable with respect to the lower pile sinker, so that the height position of the pile loop pawl on which the pile yarn is placed is adjusted. A dense pile knitted fabric having pile loops having different heights can be knitted in the same wale.
