Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention efficiently performs a transfer pattern necessary for knitting a rope pattern, a cross pattern, a formed pattern in which the number of stitches is sequentially reduced, and a knitting pattern in combination with each pattern. Regarding the transfer method to be performed.

[0002]

2. Description of the Related Art In the conventional transfer method, it is necessary to move a carriage incorporating a transfer cam to the left and right to transfer to a predetermined knitting needle, and to move the carriage sequentially to the knitting needle for transferring. , It took time for the carriage to move. For example, when transfer is required at the left end and the right end of the knitting width such as a reduced portion of the formed knitting, the carriage is moved from the left end to the right end and both transfer are performed.

[0003]

In the case of the transfer of the conventional method as described above, the time during which the carriage travels to the right end after the transfer at the left end does not contribute to knitting at all and is a dead time. In particular, when knitting a pattern having a lot of transfer operations, the ratio of this wasted time increases, and it takes a long time for knitting, resulting in a very bad productivity of the knitting machine. It was

The inventors of the present invention have solved this problem by an innovative knitting method in which a plurality of knitting needles each having an actuator are arranged, and a knitting motion can be performed by giving a sliding motion based on a predetermined knitting plan (special feature: (Kaisho 62-282051)
It has been found that can be solved by.

[0005]

That is, the first aspect of the present invention
Are a plurality of knitting needles that are individually provided with actuators and are arranged in parallel in a plane, and a plurality of knitting needles that slidably support the plurality of knitting needles and extend left and right along the plane. Knitting needle guide member that defines the interval of at least 1
Using a flat knitting machine that includes a traveling platform that reciprocates in the left-right direction along the knitting needle guide member, using the flat yarn knitting device, the position of the yarn supplying device on the traveling platform is detected. ,
In a knitting method of a knitted fabric, a signal based on a predetermined knitting plan is applied to an actuator of each corresponding knitting needle to thereby give a sliding motion based on the predetermined knitting plan to the knitting needle to perform the knitting motion. The transfer method is characterized in that all the knitting needles perform a transfer operation simultaneously in a predetermined course, and the second invention is that in the first invention, a plurality of knitting needles are appropriately divided into zones on the knitting bed. The transfer method is characterized in that predetermined needles to be transferred in each of the zones are sequentially transferred with a predetermined time delay, or the transfer operation is simultaneously advanced between the respective zones. In a third aspect of the present invention, when a plurality of knitting needles perform a transfer operation, the transfer operation is performed in a direction from the front to the back or from the back to the front. The mixed is a method of performing transferred eyes.

Hereinafter, the present invention will be described in JP-A-62-282051.

EXAMPLE In the present example, the method of the present invention and the conventional method will be described by comparison with a pattern in which 2 × 2 rope patterns are located on the left and right of the knitted fabric.

[0008]

[Embodiment 1] FIG. 1 shows an embodiment of the simultaneous transfer method of the present invention, and FIG. 2 shows a conventional transfer procedure. That is, a case is shown in which a 2x2 rope is knitted in zone A and zone B, and stitches are transferred between A and B. Where: No. 1, 2, 3, 4, 5, 6, 7, 8 are zone A,
Zone B shows the loop to be moved in each zone.

The knitting beds are at the front and back.・ ○ indicates the front loop, × indicates the back loop. | Indicates a knitting needle without a loop.・ ↑ indicates the movement of the loop from front to back.・ ↓ shows the operation to move the loop from the back to the front.

It is assumed that the loop is at the front and the bed is at the meeting position. The zone A No. of (step (1)) of the present invention. No. 1, 2, 3, 4 loops and Zone B No. According to the present invention, a loop of 5, 6, 7, and 8 (see FIG. 1) is moved from the front bed to the back bed at the same time (step (2)). For this reason, the time required for the transfer is shortened by the time required for the carriage to move from the zone A to the zone B as compared with the conventional case.

In comparison with the conventional transfer procedure (see FIG. 2), since the carriage moves from zone A to zone B and transfer is possible, zone No. 1, 2,
The transfer is sequentially performed in the order of 3 and 4 [FIG. 2 of the conventional method (see step (2))]. Further, the carriage moves to the zone B and the No. The transfer is sequentially carried out in the order of 5, 6, 7, and 8 [FIG. 2 of the conventional method (see step (3))].

Next, in the present invention, the back bed is moved to the left 2
Shake the pitch [FIG. 1 of the present invention (see step (3))].
Then, in No. A of zone A. Nos. 3 and 4 loops and zone B No. According to the present invention, in which 7 and 8 are simultaneously transferred from the back bed to the front bed [see step (1) of FIG. 1]. In comparison with the conventional transfer procedure (see FIG. 2), the carriage moves from zone B to zone A and transfer is possible, so No. The transfer is sequentially performed in the order of Nos. 8 and 7 [see FIG. 2 of the conventional method (see step (6)]], the carriage moves to the zone A, and No. The transfer is sequentially performed in the order of 4 and 3 [FIG. 2 (steps (7) and (8) of the conventional method).
reference)〕.

Next, in the present invention, the back bed is moved to the right 4
Shake the pitch [FIG. 1 of the present invention (see step (5))].
Zone A No. No. 1 and 2 loops and Zone B No.
The loops 5 and 6 are simultaneously transferred from the back bed to the front bed [FIG. 1 of the present invention (see step (6))].

In comparison with the conventional transfer procedure (see FIG. 2), since the carriage moves from zone A to zone B and transfer is possible, no. The transfer is sequentially carried out in the order of 1 and 2 [see FIG.
No. 0))], the carriage moved to zone B and No.
The transfer is sequentially performed in the order of 5 and 6 [FIG. 2 of the conventional method (see steps (11) and (12))].

Thus, comparing the simultaneous transfer method of the present invention with the conventional transfer method, when the time for the carriage of the conventional method to move from zone A to zone B or from zone B to A is t, In the case of 3 times, it takes 3 t for convenience, but in the case of the present invention, this time is shortened.

[0016]

[Embodiment 2] In the case of knitting a thread having poor slipperiness, many mistakes may occur in the simultaneous transfer of the entire course of the present invention. Even in such a case, the present invention, for example, when the transfer is at the end of the knitted fabric, the zone A and the zone B are
The transfer operation is divided into and, and the transfer operation in each zone is performed with a time delay, and the transfer operation is sequentially performed as if the transfer cam is performing transfer, or each zone is moved. In the meantime, it is possible to perform a transfer method in which the transfer operations are carried out in parallel and at the same time.

Also in this case, the transfer is sequentially performed in each of the subdivided zones (for example, the A zone and the B zone), and the transfer operation is simultaneously performed between the zones, so that the carriage is moved between the zones. According to the present invention, this useless time is eliminated and the time can be shortened as compared with the case of the conventional method in which the vehicle runs.

[0018]

[Embodiment 3] FIG. 3 shows a shape of a side stitch to be knitted, and FIG. 4 shows an efficient transfer method of the present invention in an example taking the side stitch of FIG. 3 as an example. Is. (The symbols used in the figure are the same as those in FIGS. 1 and 2.)
Shows the conventional transfer method by taking the cross stitch of FIG. 3 as an example.

In FIG. 3, two front loops in zone A move one stitch to the right and one back loop moves two stitches to the left, and in zone B two front loops move one stitch to the left,
It shows a state in which a cross stitch in which one back loop moves two stitches to the right exists in the same course. When knitting this pattern, knitting time is shortened if racking is reduced as much as possible, and FIG. 4 shows a transfer procedure in consideration of this.

In this case, the number of times of racking is four times. This means that there is no restriction on the direction of transfer, and as shown in step (2), loop 3 is moved from back to front in zone A, and loops 5 and 6 are moved simultaneously from front to back in zone B in different directions. Because you can. In the conventional transfer procedure, in the case of one cam (see FIG. 5), it takes a dead time for the carriage to travel from zone A to zone B, and in steps (2) and (12) both zone A and zone B are the same. You can only transfer to the direction, so you need to rack the racket 5 times.

As described above, in this embodiment, the dead time of the carriage traveling can be reduced and the number of times of racking can be further reduced, so that the knitting time can be further shortened and the transfer can be efficiently performed.

[0022]

As the number of courses with transfer is large, the knitting time is shortened as shown in the first embodiment. Further, as shown in Examples 2 and 3, when there are a plurality of transfers in the same course, an efficient transfer procedure can be selected from the relationship between the zones having the transfers and the knitting time can be shortened. It is possible.

Further, in the conventional knitting method, there was a restriction on the transfer procedure depending on the position of the carriage when performing the transfer, but in the present invention, the zone for transferring the transfer can be arbitrarily selected, and there are restrictions as in the conventional method. Since there is no such pattern, even patterns that are difficult to knit can be knitted using procedures that are easy to knit. For example, when the number of stitches is reduced due to molding and the number of stitches is reduced, and when the rope pattern is in the same course, the order of reduction reduction and rope movement can be arbitrarily selected as a procedure for easy knitting.

For this reason, it is possible to knit a beautiful transfer pattern knitted fabric without a mistake in a short time.
