Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanism for selecting the positional relationship between the needles and sinkers and creating a sinker pattern in a circular knitting machine using latch needles and sinkers. In particular, it is used to perform reverse knitting and pile (terry) patterning on circular shoe bottom knitting machines.

FIG. 1 shows a conventionally considered sinker 1 with stepped butts. In the conventional method, step 1
A is pushed in the direction of the arrow a with the selector finger 5, and the sinker 1 is operated for sorting in the direction of the arrow b. The disadvantages of this method are that the number of steps in the step butts 1a cannot be increased, so there is a limit to pattern changes, and because the step butts 1a are formed directly on the sinker 1, there is no mechanical strength, compared to a normal sinker without steps. The disadvantage is that the rotation speed of the knitting machine must be slowed down. The sinker design method of the present invention eliminates these drawbacks and allows the sinker to perform the sorting and horizontal movement using a more efficient method.

FIG. 2 is a side view showing the principle of the present invention, in which a sloped surface 2a is formed on the lower surface of the sinker 2, and the sinker selector jack 3 below the sinker selector jack 3 is raised in the direction of arrow c to move the jack head 3a onto the sinker slope. 2a to impart horizontal movement to the sinker 2 in the direction of arrow b.

Fig. 3 is a diagram showing the knitting operation of the sinker 2, sinker selector jack 3, and needle 4 when creating a pile pattern according to the principle of the present invention. It shows the state that has been applied. When the sinker selector jack 3 rises in the direction of arrow c from this state, the sinker 2 is moved in the direction of arrow b, and the pile yarn 7 is placed on the upper sinker jaw 2b. B shows a state in which the needles 4 have descended in the direction of arrow d to knit stitches. At this time, the sinker selector jack 3 has reached the rising point, the sinker 2 is in the pile position, the pile thread 7 is attached to the upper sinker pawl 2b to form a long sinker loop 7a, and the ground thread 6 is attached to the small sinker pawl 2c. Glue regular short sinker loop 6
It becomes a. If the sinker selector jack 3 does not rise, the sinker 2 will remain in the state shown in Figure A and the stitches will be knitted, and the pile yarn 7 and ground yarn 6 will be placed on the same sinker pawl 2c, forming a normal short sinker loop. Become.

In this way, in the present invention, by selecting the operation of the sinker selector jack 3, it is possible to create a pile pattern by forming a pile structure part and a normal plain knitting structure part without pile in the knitted fabric. can.

FIG. 4 shows a sectional view of a cylinder when the present invention is applied to an actual circular sock knitting machine. The sinker selector jack 3 is inserted into the slit 101 of the cylinder 10, and the butt 3b is inserted into the jack 3.
It has more than 10 stages of selector bats 3c. This selector butt 3c is raised by a selector finger 9 of a conventional needle selection solenoid actuator 8 to select the sinker pattern. All but one stage of selector butts 3c are removed, and the selector finger 9 corresponding to the remaining selector butt 3c acts on that selector butt 3c. The selector finger 9 moves in and out in the direction of arrow e by a pulse current applied to the solenoid 91. sinker 2
are inner sinker ring 11 and outer sinker ring 1
It's in the 3rd slot. Since the sinker 2 is held down by the lower surface of the sinker cap 12 and the inner sinker ring 11, it does not move upward when the sinker selector jack 3 is raised, so the sinker remains horizontal as explained in Fig. 3. be moved in a direction.

FIG. 5 is a sketch showing the cylinder of the circular sock bottom knitting machine of the present invention. The cylinder 10 has cylinder slits 101, 102, 103, 104,
... is cut, odd number slits 101, 10
3, ... contains sinker selector jack 3, and even numbered slits 102, 104, ... contain needle 4.
and a needle selector jack 40.

The butt 3b of the sinker selector jack 3 that has been subjected to the sorting operation by the selector finger 9 passes over the sorting cam 16, and then passes over the cam 16 at the knitting position.
It is raised by a. Since the butt 3b of the sinker selector jack 3 which is not operated passes under the distribution cam 16, the lifting operation at the knitting position is not performed. The needles 4 are lowered by the stitch cam 14 to perform a knitting operation. By dividing the upper half of several rows of selector butts 3c into sinker selector butts and the lower half into needle selector butts, it is possible to perform needle patterning by conventional needle selection at the same time.

In this way, in the present invention, if the number of needles in the knitting machine is N, the number of cylinder slits in the knitting machine is 2N, and needle selector jacks and sinker selector jacks are inserted alternately to perform needle selection and sinker selection at the same time. be able to. The pattern command method can be performed using a conventional mechanical pattern pin drum or by computer patterning using a microcomputer and actuator.

In FIG. 5, the jack leveling cam 17 is a cam for leveling the height of the jack butt 3d. Cylinder 10 rotates in the direction of arrow f. In the figure, only one pair of sinkers and needles that go into each slit is shown for clarity.

Figure 6 is a plan view showing an example of socks manufactured by the method of the present invention. Handle portion 19 shown with diagonal lines in the figure
The heel part 20, foot part 21, and toe part 22 are pile knitted, and the leg part 18 and instep side 23 are shown to be ordinary plain knitted.

FIG. 7 shows the knitting structure of patterned pile knitting, in which the ground yarn 6 and the pile yarn 7 are knitted, and the sinker loop 7a of the pile yarn 7 is lengthened to form a pile (terry). The part 7b where the sinker loop is not long is a normal flat knit.

As described above, the present invention completely changes the conventional sinker patterning method, and allows the movement of sinkers to be selected individually with a simple structure. It has the characteristics of being able to handle high-speed rotation. This explanation describes pile pattern creation, but reverse knitting patterns in which the front and back yarns of the knitting yarn are reversed using a sinker are also described when the top 2 of the sinker is used.
It can be performed using exactly the same principle by simply changing the shapes of b and the small peg 2c.
