Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pattern forming method for knitting an intarsia knitted fabric and a boundary portion of a color block thereof.

[0002]

2. Description of the Related Art Conventionally, when knitting an intarsia knitted fabric with a flat knitting machine, the seams of a plurality of color blocks constituting the knitted fabric are roughly knitted by either a knit joint or a tack joint. ing.
Therefore, in one intarsia knitted fabric, the seam structures of the color blocks are all the same.

[0003] In general, knit joints have high strength at joints and clean longitudinal joints, but are bulky on the other hand. Tack joints are good in terms of flatness, but the joint strength is weak and holes are easily formed in the joint when pulled in the width direction. As described above, each joint structure has advantages and disadvantages in terms of strength, appearance, form, and the like.

[0004] As described above, according to the conventional method of knitting an intarsia knitted fabric, the seam structure at the boundary portion is limited to one. In the combination, the contour of the seam was not broken, and the knitted fabric of the target quality could not be knitted.

[0005]

OBJECTS OF THE INVENTION It is an object of the present invention to enable the boundaries of a plurality of color blocks to be knitted by a suitable seam organization for each course and to overcome the disadvantages of the prior art.

[0006]

According to the present invention, when creating an automatic knitting pattern for knitting an intarsia knitted fabric with a flat knitting machine, a seam knitting pattern of a color block constituting the intarsia knitted fabric is provided. By selecting based on a predetermined selection criterion, knitting is performed with an appropriate knitting structure according to the knitting position of each course, and the drawbacks of the prior art are solved.

Here, the selection criteria for the seam structure are knitted seams where force is applied to the seam, and tack seams where the force is not applied, or the strength of the color block yarns, depending on the clothing. Correspondingly, a portion knitted with a weak yarn is knit joint, and a slanted seam is a tack seam corresponding to the inclination of the boundary (seam) of the color block with respect to the wale. The highest priority of the selection criterion is usually strength.

[0008]

FIG. 1 shows knitting needles 1 and 2 at the boundary X of a color block corresponding to two color blocks of an intarsia knitted fabric 5. The two color blocks are adjacent to each other at a boundary X line in the wale direction. Further, among the needles 1 and 2, adjacent needles particularly at positions sandwiching the boundary X are indicated by 1x and 2x. The advance and retreat movements of the needles 1 and 2 are performed by an actuator provided for each of the needles 1 and 2 and a control device that drives the actuator in synchronization with the movements of the two yarn feeders 3 and 4 based on a carriageless drive system. The drive is controlled. Of course, the two yarn feeders 3, 4 reciprocate in the course direction with each block width to supply the color block yarn 6 and the color block yarn 7.

Next, FIG. 2A shows the structure of the knit joint at the boundary X between the color blocks. And (2) and (3) of FIG. 2 have shown the description of knitting by knit joint, respectively. In these figures and FIG. 3 described later, K indicates a knit, T indicates a tack, and ← and → indicate knitting directions. (K) represents a special knit form.

According to the knitting pattern shown in FIG. 2 (2), the needles 1, 1x, 2, 2x and the yarn feeders 3, 4 are driven as follows. At the start of Step 1, the yarn 6 to be knitted for the color block is held at one end thereof in the ostium by the needle 1x, and the intermediate portion thereof stands by on the group of needles 1 to knit the color block. It is held at the yarn feeder 3 and is not knitted by the needle 2 group. Then, the yarn 7 to be knitted in the color block is knitted by the movement of the yarn feeder 4 to the left side and the knitting motion of the group of needles 2 associated therewith (step 1 is completed). At the time of completion of the knitting, the yarn feeder 4 is located on the left side of the needle 2x.

Next, the yarn feeder 3 moves rightward until the yarn 6 held between itself and the needle 1x is positioned behind the needle 2x at the position of the needle 2x. After that, needle 2x
When the yarn feeder 3 moves to the left in the process of rising to the clearing position and then descending to the tack position, the yarn 6
Is turned back by the needle 2x and passes through the front side of the needle 2x. Then, when the needle 2x is further retracted to a position just before the knockover position, that is, to the half-down position, its own vera is closed by the loop of the thread 7 formed earlier, and the folded front thread 6 becomes the needle 2x. Caught on. Thereafter, the needle 2x is maintained at the half-down position, and the two yarns 6, 7 are moved in the state shown in FIG.
It is held near the tooth opening by x. Next, the yarn feeder 4 moves to the right and waits at a position where the yarn 7 is not caught by the needle 1 group, for example, just above the needle 2x, while the yarn 6 is moved to the left as the yarn feeder 3 moves further left. Knitted into groups (step 2 completed).

Next, the yarn feeder 3 which has been moved to the left side of the group of needles 1 has been moved to the right side of the needle 1x, and
The group performs the knitting motion, and all the needles 1 complete the knitting of the yarn 6 (Step 3 is completed).

Next, the yarn feeder 4 moves to the left until the yarn 7 held between itself and the needle 2x is located behind the needle 1x at the position of the needle 1x. Then needle 1x
When the yarn feeder 4 moves rightward in the process of rising to the clearing position and then descending to the tack position, the yarn 7 is folded back by the needle 1x and passes through the front side of the needle 1x. Then, when the needle 1x is further retracted to the half-down position, its own vera is closed by the loop of the previously formed thread 6, and the folded thread 7 is caught by the needle 1x. Thereafter, the needle 1x is maintained at the half-down position, and the two yarns 6 and 7 are held near the tooth gap by the needle 1x in a state opposite to (4) in FIG. Next, the yarn feeder 3 moves to the left and waits at a position where the yarn 6 is not caught by the needle 2 group, for example, just above the needle 1x, while the yarn 7 moves to the right as the yarn feeder 4 moves further to the right. Knitted into two groups (Step 4 completed). In this step 4, the two yarns 6, 7 held by the needle 2x come off the needle 2x, and two old loops are formed. At the same time, a new loop is formed by the newly supplied yarn 7. You. When these two old loops are formed, the yarn 7 that has previously formed the loop appears on the surface.

In the next repeated step 2,
At the completion of step 4, the two yarns 6, 7 held by the needle 1x are separated from the needle 1x to form two old loops, and at the same time, a new loop is formed by the newly supplied yarn 6. Is done. When these two old loops are formed, the yarn 6 appears on the opposite side.

In steps 2 and 4 above, the knitting of the needles 1 or 2 is started after the needle 2x or the needle 1x is located at the half-down position, but it is not always necessary to do so. The yarn feeders 3 and 4 are continuously moved as in the case of ordinary flat knitting, and the needle groups 1 and 2 raised are moved to the needles 2x or the needles 1x.
You may make it fall sequentially according to the fall of x.

According to the knitting pattern shown in FIG. 2C, the needles 1, 1x, 2, 2x and the yarn feeders 3, 4 are driven as follows. At the start of Step 1, the yarn feeder 4 is located at a position where the yarn 7 held by itself is not caught by the needle 1 group corresponding to the color block, for example, to the right of the needle 2 group. Then, the yarn 6 to knit the color block
Feeder 3 that feeds yarn 1 is a needle 1 corresponding to a color block.
As you move from the right side to the left side of the group,
The group performs a knitting motion, and only the yarn 6 is knitted with the entire needle 1 group (Step 1 is completed). At the time of completion of the knitting, the yarn feeder 3 is located on the left side of the needle 1 group.

Next, as the yarn feeder 4 moves to the left,
The needle 2 group performs a knitting motion, the yarn 7 is knitted by the entire needle 2 group, and the yarn feeder 4 further moves the yarn 7 held between itself and the needle 2x on the back side of the needle 1x at the position of the needle 1x. Move left until you find it. Thereafter, when the yarn feeder 4 moves rightward in the process of lowering the needle 1x to the clearing position and then to the tack position, the yarn 7 is folded back by the needle 1x and passes through the front side of the needle 1x. Become. There, the needle 1x is further retracted to the half-down position, its own wrench is closed by the previously formed loop of thread 6, and the folded thread 7 is caught by the needle 1x. Thereafter, the needle 1x is maintained at the half-down position, and the two yarns 6 and 7 are held near the tooth gap by the needle 1x in a state opposite to that in FIG. 4D (Step 2 is completed).

The start of the operation in step 2 does not necessarily have to be performed after step 1 is completed, and the start of step 2 may be earlier than the start of step 1. The position of the yarn feeder 4 may be controlled so that the yarn 4 is not caught by the needle 1 group. Therefore, according to this knitting pattern, the knitting of the color blocks can be performed at the same time, and the knitting time can be shortened.

The yarn feeder 4 further moves to the right and exceeds the right end of the color block. In accordance with the movement, the needles 2 perform knitting motion, and the yarns 4 are knitted by all the needles 2 (Step 3 is completed). .

Next, the yarn feeder 3, which has been located beyond the right end of the color block, moves to the right, and in accordance with the movement, the entire needle group performs a knitting operation, and the yarn 3 is knitted.
Further, when the yarn feeder 3 moves beyond the needle 2x and the yarn 6 held between itself and the needle 1x is positioned behind the needle 2x at the position of the needle 2x, the needle 2x moves up to the clearing position. When the yarn feeder 3 moves to the left in the process of descending to the tack position after rising, the yarn 6
Is turned back by the needle 2x and passes through the front side of the needle 2x. Then, when the needle 2x is further retracted to the half-down position, its own vera is closed by the loop of the previously formed thread 7, and the folded thread 6 is caught by the needle 2x. Thereafter, since the needle 2x is maintained at the half-down position, the two yarns 6 and 7 are held near the tooth gap by the needle 2x in the state of (4) in FIG. 2 (Step 4 is completed).

The operation of step 4 is also started in step 2
Similarly to the above, it may be earlier than the start of step 3, that is, the position of the yarn feeder 3 may be controlled so that the yarn 3 is not caught by the needle 2 group at the start of step 3. Therefore, according to this knitting pattern, the knitting with the color blocks can be performed simultaneously in these steps, and the knitting time can be shortened. When the needle 1x completes the knitting in step 4, the two yarns 6, 7 held by the needle 1x come off from the needle 1x to form two old loops, and at the same time, the newly supplied yarn. 6 forms a new loop. When these two old loops are formed, the yarn 6 appears on the surface. In this way, steps 1 to 4 are repeated, but when the next step 2 is completed, the thread 7 will appear in the table out of the two old loops off the needle 2x.

Next, FIG. 3A shows the structure of the tack joint at the boundary X between the color blocks, and FIG. 3B shows the explanatory diagram of the knitting of the tack joint. I have. According to the knitting pattern, the yarn feeder 3 moves rightward as shown in step 4, and the needle 1 knits one course of the color block. Then, as shown in Step 1, after the needle 2x tacks the yarn 1, the yarn feeder 3 moves to the left, and one course of the color block is knitted again.

After the yarn 6 is tacked by the needle 2x, as shown in step 2, one course of the color block is knitted in accordance with the yarn feeder 4 moving leftward. Then, as shown in step 3, after the needle 1x tacks the yarn 7, the yarn feeder 4 moves rightward and one course of the color block is knitted again. After the thread 7 is tacked by the needle 1x, as shown in step 4, one course of the color block is knitted in accordance with the yarn feeder 3 which has moved rightward. Also in this case, the color block thread 6 and the color block thread 7
Can be simultaneously knitted, so that knitting time can be reduced.

In the above description, the knitting pattern of the knit splicing and the tuck splicing has been described in which two courses constitute one cycle. However, only the first half or the latter half of the course may be used as the knitting pattern. These seam organizations may be selected for each course based on the above-described seam organization selection criteria. Therefore, the operator
When creating a knitting pattern for one knitted fabric 5, a knitting pattern suitable for the selected seam structure may be selected as a knitting pattern for the seam portion. By driving the needles 1 and 2 and the yarn feeders 3 and 4 based on the knitting pattern created in this manner, a desired intarsia knitted fabric 5 can be obtained.

In this manner, for one intarsia knitted fabric 5, knit joints and tack joints are mixed as a joint structure at the boundary X. As a result, for the intarsia knitted fabric 5, the characteristics of the knit splicing and the tack splicing exist in an appropriate state according to the knitting shape such as strength, thickness, and inclination position.

[0026]

According to the present invention, an appropriate seam structure is selected for each boundary position of the intarsia knitted fabric, so that the appropriate stitch strength, stitch thickness, stitch direction, and the like are appropriate for each boundary position of the color block. Can be set, a high value-added intarsia knitted fabric can be provided for a product having a single stitch structure for one conventional intarsia knitted fabric.
