Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for knitting a spliced fabric using a plurality of different types of knitting yarns.

[0002]

2. Description of the Related Art Among a plurality of yarn feeders, at least two yarn feeders each having a yarn guide hole are made to run simultaneously at a predetermined interval, thereby supplying a plurality of types of knitting yarns to a predetermined knitting needle, that is, a knitting needle. A method for knitting a spliced yarn knitted fabric has been proposed (Japanese Patent Laid-Open No. 5-321101). In this conventional knitting method, each knitting needle is moved back and forth in a predetermined pattern by an actuator such as a linear motor.

As one example of the reciprocating movement pattern of the knitting needle, as shown in FIG. 4, the vertical axis represents the movement amount of the knitting needle when the position of the needle bed gap is zero, and the vertical axis represents the time or the movement amount of the yarn feeder. It can be represented as a diagram. Such patterns are called cam diagrams, cam patterns, knit patterns, needle movement patterns, and the like. In the present invention, the reciprocal movement pattern of the knitting needle is referred to as a “knit pattern”.

According to the above conventional knitting method, during knitting,
By changing the running order of the at least two yarn feeders, the knitting yarns appearing on the surface of the knitted fabric are switched, and thereby it is possible to set a pattern having a free color or texture. However, in the conventional knitting method, since the distance between at least two yarn feeders is constant during knitting, the types of knitting patterns that can be expressed are limited to combinations of the running order of the yarn feeding ports, and as a result, knitting patterns that can be expressed. The color and texture of the are limited.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to express a knitting pattern having a greater number of shades or textures in a splicing stitch.

[0006]

SOLUTION, OPERATION, AND EFFECT The knitting method of the spliced yarn knitted fabric of the present invention comprises at least two knitting yarns of different kinds.
Supplying a plurality of knitting yarns to a predetermined knitting needle at the same time by running the two yarn feeders at the same time;
Changing the interval of one yarn feeder once or more based on the knitting plan.

Even if the plurality of yarn feeders have the same running sequence, if the interval between the leading yarn feeder and the so-called trailing yarn feeder subsequent thereto is changed so as to increase or decrease, the knitting needle The positional relationship of the plurality of knitting yarns, in particular, the degree of the front-rear relationship when the yarn is drawn in due to changes slightly, and the appearance of the knitting yarns that should appear on the surface of the knitted fabric also changes delicately.

As a result, by inserting knitting yarns of different colors into the yarn feeder, it is possible to express a subtle color shade. Also, by inserting knitting yarns having different thicknesses and physical properties (fluffiness etc.) into the yarn feeder, it is possible to express a delicate texture. Furthermore, by inserting knitting yarns having different colors and different thicknesses or physical properties into the yarn feeder, it is possible to express delicate color and texture.

According to the invention, at least 2 during knitting
Since the interval between the two yarn feeders is changed once or more based on the knitting plan, it is possible to produce more colors or textures in the knitting pattern than in the conventional splicing knitting.

The spacing of the yarn feeders may be changed for each knitting pattern portion adjacent in the course direction, or may be changed for each knitting pattern portion adjacent in the wale direction, and further in the course direction and the wale direction. You may change it for every adjacent knitting pattern part. When three or more yarn feeders are used, the first and second
It is possible to change the spacing selected from the spacing of the yarn feeders, the spacing of the second and third yarn feeders, and the spacing of the first and third yarn feeders one or more times.

It is preferable not only to change the intervals of the yarn feeders, but also to change the running order of at least two yarn feeders, the running speed of the yarn feeders or the knit pattern once or more during knitting. As a result, a knitting pattern having more colors and textures can be expressed.

The running order of the yarn feeder, the running speed of the yarn feeder, and the knit pattern may be changed for each knitting pattern portion adjacent in the course direction or for each knitting pattern portion adjacent in the wale direction. Alternatively, the knitting pattern portions adjacent to each other in the course direction and the wale direction may be changed.

BEST MODE FOR CARRYING OUT THE INVENTION Referring to FIG.
The knitted pattern portion 12, 14, 16, 18, 20 is connected to the hem rubber knitted portion 22 to form a knitted fabric. In this plain knitted fabric 10, two types of knitting yarns are used to form two rows of diamond pattern knitted pattern portions 14 and 18 and other knitted pattern portions 12 and 16 of the plain knitted fabric.
By using a knitted fabric having a color or texture different from that of No. 20, a pattern is given.

The knitting machine used for knitting the plain knitted fabric 10 is preferably, for example, a so-called carriageless flat knitting machine that does not include a carriage for a cam that reciprocates a plurality of knitting needles according to a predetermined knit pattern. A carriageless flat knitting machine moves each of a plurality of knitting needles back and forth individually by an actuator such as a linear motor,
Each knitting needle is individually reciprocated in synchronization with the movement of the yarn feeder. One of such carriageless flat knitting machines is described in Japanese Patent Publication No. 12855/1989.

In the example shown in FIG. 2, for knitting the plain knitted fabric 10, at least two yarn feeders 24 and 26 each having one or more yarn guide holes and a plurality of yarn feeders arranged in parallel on the needle bed are provided. The flat knitting machine including the knitting needles 28 and the top teeth 30 located between the adjacent knitting needles 28 is used. Each yarn feeder is reciprocated by a yarn supplying device, and each knitting needle is reciprocated by an actuator, preferably a linear motor, in synchronization with the movement of the yarn feeder. Different types of knitting yarn 32 and knitting yarn 34 are inserted through the yarn feeders 24 and 26, respectively.
In FIG. 2, the direction of movement of the yarn feeder with respect to the knitting needle is indicated by arrow 3
Shown by 6.

Next, by changing the interval L between the yarn feeders 24 and 26 to L1 and L2 in each course C, the course C is changed.
Describe how to organize n.

The course Cn is knitted by moving the yarn feeders 24 and 26 from left to right in FIG. Therefore, the next course Cn + 1 is the yarn feeder 24,2.
Knitting is performed by moving 6 from right to left in FIG. L1 and L2 are selected so that L1 ≠ L2, that is, L1> L2 or L1 <L2, based on a predetermined knitting plan. L1 and L2 can be 20 mm and 10 mm, respectively.

After the yarn feeder 24 or 26 is moved to set the interval L of 26 to L2, the yarn feeders 24 and 26 are simultaneously moved at the same speed S in a state where the yarn feeder 24 precedes the yarn feeder 26. Knitting needles from No. to N100. As a result, the knitted pattern portion 12 of the course Cn is knitted.

Next, the yarn feeders 24 and 26 are idled to the left side zone of the knitting needle N101 and temporarily stopped at that position,
After moving only the yarn feeder 26 to the left in order to set the distance L between the yarn feeders 24 and 26 to L1, the yarn feeders 24 and 26 are moved at the same speed S at the same time with the yarn feeder 24 preceding the yarn feeder 26.
Knitting with knitting needles from N101 to N140 by running at. As a result, the diamond pattern portion 14 of the course Cn is knitted.

Next, the yarn feeders 24 and 26 are idled to the left side zone of the knitting needle N141 and temporarily stopped at that position,
After moving only the yarn feeder 26 to the right in order to set the distance L between the yarn feeders 24 and 26 to L2, the yarn feeders 24 and 26 are moved at the same speed S at the same time with the yarn feeder 24 preceding the yarn feeder 26.
Knitting with the knitting needles from N141 to N260 by running at. As a result, the knitting pattern portion 1 of the course Cn
6 are organized.

Next, the yarn feeders 24 and 26 are idled to the left side zone of the knitting needle N261 and temporarily stopped at that position,
After moving only the yarn feeder 26 to the left in order to set the distance L between the yarn feeders 24 and 26 to L1, the yarn feeders 24 and 26 are moved at the same speed S at the same time with the yarn feeder 24 preceding the yarn feeder 26.
Knitting with N261 to N300 knitting needles. As a result, the diamond pattern portion 18 of the course Cn is knitted.

Next, the yarn feeders 24 and 26 are idled to the left side zone of the knitting needle N301 and temporarily stopped at that position,
After moving only the yarn feeder 26 to the right in order to set the distance L between the yarn feeders 24 and 26 to L2, the yarn feeders 24 and 26 are moved at the same speed S at the same time with the yarn feeder 24 preceding the yarn feeder 26.
Knitting with the knitting needles from N301 to N400 by running at. As a result, the knitting pattern portion 2 of the course Cn
0 is organized.

When knitting the next course Cn + 1, when the yarn feeders 24 and 26 reach the right end in FIG. 1, after the yarn feeder 24 is moved to the left side of the yarn feeder 26, In the opposite of the case, that is, from right to left in FIG. The number of stitches when knitting a given course is greater than the number of stitches when knitting the previous course.
Increase or decrease one by one.

For example, in the example of the knitting portion shown in the figure, the width dimension of the knitting pattern portions 14 and 18 of the diamond pattern is the course Cn-1.
, Cn, Cn + 1, ..., The knitting pattern portions 12, 14, 16, 18, and 20 are N1 to N99, N100 to N141 in the case of the course Cn-1, respectively.
, N142 to N259, N260 to N301 and N302 to N4.
Knitting with 00 knitting needles, N1 to N1 for course Cn

And N301 to N400 knitting needles, and in the case of course Cn + 1, N1 to N101, N102 to N139, N140 to
It is knitted by knitting needles N261, N262 to N299 and N300 to N400. In the case of a knitting point where the width dimensions of the diamond pattern knitting patterns 12 and 14 are gradually increased, the above procedure is reversed.

While the yarn feeders 24 and 26 are moved as described above, the knitting needles 28 are advanced and retracted with respect to the moving paths of the yarn feeders 24 and 26 in a knit pattern as shown in FIG. 4, for example. In the knit pattern of FIG. 4, the knitting needle waiting at the position of the needle bed first protrudes upward from the position of the needle bed gap,
Next, the knitting yarn is retracted toward the needle bed gap side by a predetermined distance and stopped at that position for a predetermined period of time T, then retracted to the needle bed gap position, and further downward from the needle bed gap position to form a stitch. It shows that the robot retreats, then returns to the position of the needle bed gap with the knitting yarn locked, and waits at that position.

FIG. 2 shows the relative positional relationship between the knitting yarns 32 and 34 and the positional relationship between the knitting yarns 32 and 34 with respect to the knitting needle 28 when the yarn feeders 24 and 26 travel at a distance L1.
3A and 3A, the relative positional relationship between the knitting yarns 32 and 34 and the positional relationship between the knitting yarns 32 and 34 with respect to the knitting needle 28 when the yarn feeders 24 and 26 travel at an interval L2. They are shown in FIGS. 2B and 3B, respectively. 2 and 3, P1 and P2 are the center-to-center distances of the knitting yarns 32 and 34 before they are received by the hook portion of the knitting needle 28, and P1 'and P2' are the knitting yarns received by the hook portion of the knitting needle 28. The distance between the centers of 32 and 34.

As is apparent from FIGS. 2 and 3, the distances P1 and P2 and P1 'and P2' between the knitting yarns 32 and 34 in the forward and backward movement direction of the knitting needle 28 are L1 ≠ L2, respectively. , P1 ≠ P2 and P1 '≠ P2'.
Therefore, depending on whether the distance between the leading yarn feeder 24 and the trailing yarn feeder 26 is L1 or L2,
Even if the traveling order and traveling speed of the knitting needles are the same,
The relative positional relationship of the knitting yarns 32 and 34 when retracted by, especially the degree of front-back relationship is slightly different (P1> P
2, P'1>P'2), the appearance of the knitting yarn 32 that should appear on the surface of the knitted fabric is slightly different.

As a result of the above, by using the knitting yarns 32 and 34 having different colors, the knitting pattern portion 14 having a diamond pattern is used.
It is possible to obtain a slightly different knitted fabric from the knitting pattern portions 12, 14 and 20 of 18 and other knitting patterns. Further, by using knitting yarns having different thicknesses or physical properties, it is possible to obtain a knitted fabric having a slightly different texture between the knitted pattern portions 14 and 18 and the knitted pattern portions 12, 16 and 20. Furthermore, by using the knitting yarns 32 and 34 which are different in color and different in thickness or physical properties, the hue and texture are knitted pattern portions 14, 18
It is possible to obtain a slightly different knitted fabric between the knitting pattern portions 12, 16 and 20.

For example, the knitted pattern portions 14 and 18 of diamond pattern
The appearance of the color of the knitting yarn appearing on the surface of the other knitting pattern portion 12,
The color pattern can be knitted by emphasizing the appearance of the color of the knitting yarn appearing on the surface of 16, 20. In the illustrated embodiment, when L1> L2, the knitted pattern portion 14,
The part of the knitting yarn 32 appearing in 18 is the other knitting pattern part 12, 1
Since there are more knitting yarns 34 appearing in Nos. 6 and 20, if the red knitting yarn 32 and the white knitting yarn 34 are used, the red color of the knitting pattern portions 14 and 18 is the other knitting pattern portions 12, 16, Darker than 20 red.

In the illustrated example, the knitted pattern portions 12, 14, 1
When knitting 6, 18 and 20, yarn feeders 24, 26
Is maintained at a predetermined value L1 or L2. However, the interval L of the yarn feeder may be changed once or more for each one or more courses, may be changed once or more for one course, and may be once or more for each one or more courses. It may be changed and changed more than once within one course. In particular, the spacing L between the yarn feeders is set such that the knitting pattern portions adjacent to each other in the course direction or the wale direction, for example, the knitting pattern portions 14 and 1 of diamond pattern
If it is changed every eight, the color or texture of the diamond pattern knitted pattern portions 14 and 18 adjacent in the course direction or the wale direction can be changed.

As shown in FIG. 5, the knitted pattern portion 1 of the diamond pattern.
Knitted pattern portions 14a, 18a and knitted pattern portion 1 of 4, 18
4b, 18a, and the interval L between the yarn feeders 24, 26 when knitting the knitted pattern portions 14c, 18c, respectively, L
Different values such as 1a, L1b and L1c may be used. In this case, L1a, L1b and L1c are all L
Greater than or less than 2. This makes it possible to change the color or texture of the knitting pattern portions of the diamond patterns that are adjacent to each other in the wale direction.

In order to surely capture the knitting yarn by each knitting needle, the stop period T when each knitting needle is retracted in the knit pattern shown in FIG. 4 can be changed according to the interval L between the yarn feeders 24 and 26. desirable. Specifically, it is desirable to make the stop period T proportional to the interval L.

Particularly, in the case of the plain knitted fabric including the diamond pattern as in the embodiment shown in FIGS. 1 and 5, the stop period T in the diamond pattern portions 14 and 18 is set to the other knit pattern portions 12 and 1.
It is preferable to make it longer than the stop period T in 6 and 20. This ensures that the knitting needle is supplemented with each knitting needle.

In addition to changing the interval L between the yarn feeders 24 and 26, the running order of the yarn feeders 24 and 26 may be reversed for each knitting pattern portion adjacent in the course direction or the wale direction. As a result, it is possible to change the color or texture of the diamond pattern knitting pattern portions 14 and 18 that are adjacent to each other in the course direction or the wale direction.

For example, when knitting the knitted pattern portion 14 of the diamond pattern, the yarn feeder 24 precedes the yarn feeder 26, and when knitting the knitted pattern portion 18 of the diamond pattern, the yarn feeder 26 precedes the yarn feeder 24. May be.

In this case, the formation of the course Cn is first N1.
The knitting needles from No. to N260 are knitted in the same manner as in the above-described embodiment, and then the yarn feeders 24 and 26 are idled to the left side zone of the knitting needle N261 to change the left and right positional relationship of the yarn feeders 24 and 26, and The distance L between 24 and 26 is L1
After changing to, the knitting needles from N261 to N300 are knitted by running the yarn feeders 24 and 26 simultaneously at the same speed with the yarn feeder 26 preceding the yarn feeder 24, and then the yarn feeders 24 and 26 are changed. The knitting needle N301 is idled to the left side zone, the positional relationship between the left and right yarn feeders 24, 26 is changed, and the spacing L between the yarn feeders 24, 26 is changed to L2, and then the yarn feeder 24 precedes the yarn feeder 26. In this state, the yarn feeders 24 and 26 are made to run at the same speed at the same time to knit with the knitting needles N301 to N400.

Not only two yarn feeders but also three or more yarn feeders may be used. When using three yarn feeders, one or more selected from the distance L12 between the first and second yarn feeders, the distance L23 between the second and third yarn feeders, and the distance L13 between the first and third yarn feeders. You can change the interval. The operation of knitting the course Cn shown in FIG. 1 or 5 using the three yarn feeders can be carried out as follows, for example.

First, the first, second and third yarn feeders are run simultaneously in that order up to N100 at the same speed to knit the section N1 to N100 with three knitting yarns, and then the three yarn feeders are connected. N101 to N140 are operated by idling to the zone on the left side of N101 and changing the running order of the three yarn feeders, and then simultaneously moving the second, first and third yarn feeders in that order to N140 at the same speed. The section of is knitted with three knitting yarns.

In the same manner, the sections N141 to N260 are arranged in the order of the first, second and third yarn feeders N261 to N30.
The section 0 is run in the order of the third, first and second yarn feeders, and the section N301 to N400 is run in the order of the first, second and third yarn feeders at the same speed at the same time. The section is knitted with three knitting yarns. At this time, when knitting the knitted pattern portions 12, 16 and 20, the intervals L12 and L23 of the yarn feeders are made different for each knitted pattern portion, and the three yarn feeders are run. At this time, even if the distance L12 is constant and only the distance L23 is changed, a subtle difference in color tone can be expressed. Furthermore, the fire pattern 14a,
Interval L1 for every 14b, 14c, 18a, 18b, 18c
2 and L13 may be different from each other.

As described above, the interval L, the running order of the yarn feeders, the number of yarn feeders, and the number of knitting yarns are appropriately combined according to the knitting pattern, and these combinations are adjacent to each other in the course direction or the wale direction. It is preferable to change it for each knitted pattern portion, especially for each knitted pattern portion 14, 18 of diamond pattern. In this way, the color or texture of the diamond pattern knitted pattern portions 14, 18 can be changed for each of the diamond pattern knitted pattern portions 14, 18 adjacent in the course direction or the wale direction. In particular, the distance L varies depending on the knitting pattern, knitting machine, etc.
It can be any value within the range of several cm.
