Fig. 13 is a diagram showing the relationship between a pattern jack and a drum when used in knitting machines.

The present invention develops and combines a pattern jack tooth and a selector drum pin to form a pattern of a knitting machine, and determines a pattern arrangement of a pattern jack and a pin arrangement of a selector drum. It is about.

For example, a pattern magnetic knitting machine of the siles tights, which is the object of the present invention, is generally known, but the configuration thereof will be outlined using FIG.

(1) is a selector drum (also referred to as a drum hereinafter) in which a plurality of pins b are inserted in the pinhole 1a of the outer circumference according to a pattern, and is rotated to the left about the axis 1c. (2) is a pattern jack having a plurality of teeth (2a) (hereinafter also referred to as a jack), a plurality of jacks are radially installed on the radius (R) around the axis (2b) and rotated. (3) is an arm having a hook (3a) at the front end, a projection (3b) in the center and is installed around the point (3c), a large number is installed in the Y-axis direction shown, the rear end (3d0) is a spring ( The arm 3 is tensioned by 34. The hook 3a presses the teeth 2a of the jack, and the projection 3b pushes the drum 1 or the pin 1b by means of a spring 4. It is to be crimped.

The number of pinholes in the Y-axis direction of the selector drum 1 corresponds to the number of teeth and the number of arms of the pattern jack 2, respectively. In addition, a knitting needle and a thread (not shown) are attached to the upper side of the pattern jack 2.

For example, the above-described configuration will be described using a non-transfer method and will be described using FIG. 11 of the embodiment of the present invention.

FIG. 11A shows the presence or absence of the teeth 2a of the jack 2, and the number of the jacks 2 is shown on the horizontal axis (X-axis). , 400 and the vertical axis (Y axis) represent the number of teeth 2a, for example, 1,2,3... Becomes 25. ＂1 'indicates that there is a tooth, and＂ 0' indicates no value.

11 (b) shows the presence or absence of the pin 1b0 in the pinhole 1a of the drum 1, and the vertical axis shows the number of steps of the drum 1, for example, 1,2,3 ..., 25 In the horizontal axis, the outer circumferential number of the drum 1 is shown, for example, 1,2,3, ..., 60. In addition, "1" indicates that there is a pin, and "0" indicates that there is no pin.

11 (c) shows a pattern, for example, A, B, C,... , Y, and on the horizontal axis are 1,2,3,. It is set to 400. In addition, "1" represents where a pattern is produced, and "0" represents where a pattern is not produced.

In this configuration, the patterning method is one part of the drum with one jack per row of drums 1, and there is a place where there is no pin 1b in one row of drums and corresponds to this pin 1b. If the teeth 2a of the jack 2 are located at one place, one part of the pattern shape is not generated and the pattern is generated under other conditions. In other words, the pattern {0}: pin # 0}, and the pattern {0}: pin # 0} In the case of (Q1'1: Pin 1 '), the pattern is 1'.

Under this condition, if the first column of the X axis of the jack 2 corresponds to the first row of the X axis of the drum 1, the Y axis of the first column of the X axis of the drum 1 is 2 as shown in FIG. It is assumed that the pin 1b is inserted at the 5th position.

In contrast, the Y axis in the first row of the X axis of the jack 2 has teeth 2a only at five positions. At this time, a pattern is generated at (1: A) of the eleventh (c) because the knitting machine is not a condition of (chi # 1: pin 0). The second row of the X-axis of the jack 2 corresponds to the first row of the X-axis of the drum 1. As shown in FIG. 11, the pin 1b is inserted in the 2nd and 5th axis | shafts of the 1st row of the X-axis of the drum 1 at 2,5.

On the contrary, since the Y axis of the second row of the X axis of the jack 2 has the teeth 2a only at four places (a tooth # 1: pin # 0), the second axis of FIG. A) No pattern is created.

Referring to FIG. 13, the condition that no pattern is generated is that the pin 1b is not inserted into the pin hole 1a of the drum 1 at the position of the projection 3b of the arm 3. , Teeth 2a of the jack 2 corresponding to the pin 1b, wherein the rear end 3d of the arm 3 is pulled by the spring 4 around the point 3c. When the projection 3b is in contact with the outer circumference of the drum 1, the hook 3a of the arm 3 is moved out of the correct position of the jack 2 by squeezing the teeth 2a of the jack 2, The pattern is not generated, and under other conditions, the pattern is lifted upward by the cam (not shown), so that all the patterns are generated.

In addition, the operation relationship between the drum 1 and the jack 2 is that the jacks 2 sequentially rotate as shown in this example, for example, with respect to the first row of the outer peripheral pins of the drum 1, and then the drums For example, 400 jacks 2 rotate about the second row of the outer circumferential pin of (1) as in this example. The jack 2, which has been released from the home position, is automatically returned to the home position after one rotation.

The above is the knitting method of knitting machine, but by designing this pattern and developing the pin and jack teeth of the selector drum in a pattern, conventionally, the selector drum is operated by the worker as described above while looking at the pattern design created on the desk. The pin arrangement and the tooth arrangement of the jack were determined, the pin insertion of the selector drum and the punching of the jack were performed.

However, in such a patterning method, the pattern is required to determine the expertise, for example, a very difficult task for beginners, even if you have a professional knowledge there was a problem due to the long time work. In addition, since the work is performed by the worker, there is a possibility of incorrect insertion at the time of pin insertion and a wrong setting of the punch punching position of the jack.
