Further, the needle lowering switch cam 14b is provided so as to be able to advance and retract so that the long butt needle 2b is pulled down from the non-knitting line 12 to the knitting line 13 at the end of knitting of the heel (toe), and the upper position of the center cam 5 A yarn path device 15 is provided on the machine frame 4 so as to supply a knitting yarn.

As shown in FIG. 6B, point 1
Reference numeral 6 indicates a reference position of the knitting needle cylinder 1 (a position corresponding to the center of the heel of the sock).

Therefore, in the picker device of the sock knitting machine described above, as shown in FIGS. 6A and 6B, the knitting needle cylinder 1 is rotated forward (counterclockwise) before entering the knitting of the heel.
It is rotating and has a normal knitting operation. That is,
The short butt needle 2 and the long butt needle 2b are cleared from the right side cam 9a to the right stitch cam 6a, and further,
Knitting work is performed from the center cam 5 to the left stitch cam 6b with the knitting yarn supplied from the yarn path device 15, and then the left side cam 9b returns to the tuck line. is doing. At this time, both the needle raising switch cam 14a and the needle lowering switch cam 14b are retracted to the inoperative position (FIG. 6 (A)).
reference).

As shown in FIGS. 7A and 7B, when entering the knitting of the heel, the needle raising switch cam 14a is advanced in the axial direction of the knitting needle cylinder 1, and the needle raising switch is moved. The cam 14a raises only the long butt needle 2b from the knitting line 13 to the non-knitting line 12 at the beginning of knitting of the heel.

Therefore, the short bat needle 2a that remains on the knitting line 13 over the half circumference makes knitting of the heel. At this time, the needle lowering picker 11 is pushed down from the recessed portion of the leveling cam 10 to the inoperative position below so as not to disturb the long butt needle 2b of the non-knitting line 12 (FIG. 7 (A)). reference).

Next, as shown in FIGS. 8 (A) and 8 (B), the knitting needle cylinder 1 starts to rotate in the clockwise direction by rotating in the reverse direction, so that the knitting needle cylinder 1 is finished until the knitting of the heel is completed. Is alternated between forward and reverse rotation. At the time of this reverse rotation, the first short butt needle 2 of the above knitting line 13
a is the non-knitting line 12 by the left needle lift picker 7b
(The line of the long butt needle 2b).

Next, as shown in FIGS. 9 (A) and 9 (B), when the knitting needle cylinder 1 is rotating forward, the first first knitting needle of the short butt needle 2a of the knitting line 13 is turned to the right this time. The needle lifter picker 7a makes a transition to the non-knitting line 12.

As shown in FIGS. 10 (A) and 10 (B), the knitting needle cylinder 1 repeats forward and reverse rotations repeatedly, and thereby the right needle up picker 7a and the left needle up picker 7 are picked up.
By k, the short bat needles 2a of the knitting line 13 are alternately shifted to the left and right to the non-knitting line 12 (the line of the long bat needles 2b) while gradually reducing the stitches and knitting to a predetermined knitting width.

Therefore, the non-knitting line 12 is in a state in which the long bat needles 2b are arranged and the short bat needles 2a are arranged on both sides of the long bat needle 2a in a predetermined number.

As described above, in the picker device of the sock knitting machine, the stitches of the heel of the sock are reduced by the right needle up picker 7a and the left needle up picker 7b.

Next, knitting work for increasing the heels of the sock by the needle lowering picker 11 is performed. That is, the knitting work for increasing the heels of the sock by the needle down picker 11 is performed in the reverse order described above.

On the other hand, FIG. 12 shows the increase and decrease of stitches of the knitting needle of the heel of a sock. Before entering the knitting of the heel, the knitting needle cylinder 1 is rotated in the forward rotation (counterclockwise direction). When performing the normal knitting operation and the knitting needle cylinder 1 rotates forward, the short butt needle 2a of the knitting line 13 knits the first knitting course a with the first knitting needle 2 to reduce the number of stitches, and further, When the knitting needle cylinder 1 rotates in the reverse direction, the short butt needle 2a of the knitting line 13 knits the second knitting course b with the knitting needle 2 while reducing the stitches.

In this way, the operation of knitting the heel of the sock is repeated by repeating the above-described operation to reduce the number of stitches along the gore line ho of the sock of FIG. 11, and then the knitting control circuit. Based on a command from (not shown), the short butt needle 2a of the knitting line 13 knits with the knitting needle 2 by increasing the number of stitches in the knitting course.

That is, the picker device of the sock knitting machine described above raises the long bats 2b arranged on the half circumference of the knitting machine cylinder 1 to the non-knitting line 12 above the center cam 5 by the raising switch cam 14a, and knits the knitting machine. The machine cylinder 1 changes from forward rotation to forward and reverse rotation. As the knitting machine cylinder 1 rotates forward and backward, the short butt needle 2a reduces the number of stitches by the interaction between the needle raising picker 7 and the needle lowering picker 11 to knit a predetermined course. After knitting this predetermined course, the short butt needles 2a of the non-knitting line 12 are lowered by two from the both sides to the knitting line 13 by the needle lowering picker 11 of the leveling cam 10 to knit a predetermined course while increasing the number of stitches. In addition,
The reason why the short butt needles 2a are lowered two by two to the knitting line 13 is that the needle lowering picker 11 is operating and the needle raising operation of the needle raising picker 7 is also continuing. Lower switch cam 1 after knitting a predetermined course while increasing the number of stitches
4b, the long bat 2b of the non-knitting line 12 is knitted on the knitting line 1
3, the knitting machine cylinder 1 is returned from normal rotation to normal rotation, and knitting of the heel or the like is completed.

[0018]

However, in the above-mentioned picker device of the sock knitting machine, the raising switch cam and the lowering switch cam which the long bat needle should act on the non-knitting line and the knitting line at the beginning and the end of knitting of the heel and the like. Each unit of
The left and right needle lifter picker units and needle lowering picker units occupy the knitting machine table (machine frame), so not only the installation occupying area for these becomes large, but also spirals due to the diversification of pattern knitting accompanying the fashion of socks. In addition to the main yarn supply for knitting, a multicolor motif pattern (also called cut or boss pattern) is provided with 5 pattern yarn feeders for 5 color knitting per knitting course, and a plurality of knitting needle selection needles corresponding to this are provided. Since it is desired to additionally install the needle selection device on the knitting machine table, it is difficult to install the needle raising picker unit, the needle lowering picker unit, etc. on the knitting machine table as they are.

On the other hand, since the picker device of the sock knitting machine described above is always constructed by increasing / decreasing by one knitting needle, the shape of the heel of the knitted sock is square, and this square is a foot. Since it does not match the hemispherical shape of the heel, the knitted gore line has a pointed tip that pops out, and the ironed socks wrinkle, resulting in problems such as poor quality. Thick knitted fabrics such as tones and pile knits become larger by popping out the apex of the gore line, and there are problems with both non-stretch (non-stretch) and women's stockings.

Therefore, conventionally, a means for forming a gore line in a hemispherical shape such as a Y heel, a low heel, or a circular gusset has been proposed, but these have a problem that the structure is complicated and skill is required for operability. is there.

On the other hand, knitting means such as heels and toes are provided with four yarn feeders around the knitting machine cylinder, and needle selecting devices corresponding to the respective yarn feeders are installed. A knitting machine has already been proposed (Japanese Patent Laid-Open No. 60-231852).
However, providing a plurality of needle selection devices around the knitting machine cylinder eliminates the space for installing them, and it is difficult to perform, for example, multicolor motif pattern knitting or spiral knitting of five or more colors. is there.

In order to solve the above-mentioned problems, the present invention uses a raising switch cam, a lowering switch cam, a raising picker, a lowering picker and the like for a spiral knitting, a multicolor motif pattern knitting of at least 5 colors and a knitting such as a heel. To provide a knitting method for forming a heel or the like into a hemispherical gore line with a needle selection device used for pattern knitting, a jack for needle selection, and a jack cam used for pattern knitting without incorporating. To aim.

[0023]

According to the present invention, in a sock knitting machine, a ground yarn selecting device and a first pattern yarn selecting device are arranged in a machine frame outside a knitting needle cylinder, and a plurality of other pattern yarns are arranged. When each knitting needle selecting device is arranged in the supply device and the knitting needle cylinder for knitting a heel or the like is normally rotated, the first course of knitting by forward rotation and the second course of knitting by reverse rotation are simultaneously selected. It is a method of knitting a heel or the like characterized by acting.

[0024]

According to the present invention, when the knitting needle cylinder for knitting a heel or the like is normally rotated, the knitting needle selecting device is operated by the knitting control circuit to select the knitting needle through the jack, and the knitting needle is used as the tack course. Push it up and put it through the right stitch cam, center cam, and left stitch cam, and while moving up and down the clear course
When the knitting course is knitted, at the same time when the knitting control circuit is used, the first
The knitting needles are selected in advance so as to knit the second knitting course via the jack by operating the handle yarn selecting device, and the knitting needle cylinder is reversely rotated to preselect the second knitting course. Push the knitting needle that has been needled up to the tuck course and pass it through the left stitch cam, center cam, and right stitch cam, and knit the second knitting course such as the heel while moving up and down the clear course, and repeat these operations to continue knitting needles.
