Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a first flat knitting machine.
Regarding the method of creating a course.

[0002]

2. Description of the Related Art When knitting a weft knitted fabric, the tip of the knitting yarn is caught by a gripping device, and when the knitting yarn is guided to the knitting needle by the movement of the yarn feeder in this trapped state, the knitting needle is used in the first course of knitting. Knitting is performed by setting the end of the knitted fabric near the standby position of the yarn feeder so that the knitting yarn can be reliably hooked.

In this case, there are the following problems. If the width of the flat knitted fabric is narrow, the center of the knitted fabric will inevitably shift to the standby position side of the yarn feeder from the center of the flat knitting machine, and the pulling down force of the winder will not act evenly on the knitted fabric. There were defects and irregularities.

On the contrary, when the knitting position is set so that the center of the knitted fabric coincides with the center of the flat knitting machine, the knitting yarn caught by the grasping device is first hooked from the grasping device for catching the tip of the knitting yarn. The distance to the knitting needle became large, and in the first course of knitting, a defective hooking of the knitting yarn by the knitting needle occurred. That is, in the first course, if the distance from the knitting yarn gripping device to the knitting needle that hooks the knitting yarn first is large, the knitting yarn that continues from the moving yarn feeder to the gripping device is smaller than that when the above distance is short. , Passing through a high position, that is, a position separated upward from the knitting yarn. Therefore, there is a problem that the knitting yarn is not caught even when the knitting needle descends.

This phenomenon is not limited to the first course at the time of knitting, but at the time of knitting of multicolors, the first course at the time of pulling in for waiting to knit a certain knitting yarn whose tip is captured by the gripper. Also occurs in. For this reason, there is also a problem in that the pulling-in of the knitting is not performed stably in the knitting process using multiple colors.

[0006]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a knitting needle in the first course even if the distance from the gripper for catching the tip of the knitting yarn to the knitting needle for knitting the knitting yarn caught in the gripper is large. This ensures that the knitting yarn can be hooked by the knitting yarn, and when knitting a narrow width fabric, the knitting fabric can be knitted with the center of the knitting fabric aligned with the center of the flat knitting machine. It is to make the operation stable.

[0007]

According to the present invention, in the first course, in which the knitting yarn is guided to the knitting needle by the movement of the yarn feeder while the tip of the knitting yarn is captured by the gripper,
By operating all the knitting needles located on the standby position side of the yarn feeder than the knitting needles that perform the knitting operation for the knitting yarn or a part of the knitting needles at predetermined positions, hook the knitting yarn on the knitting needle, and then, knit the yarn. By removing the stitches, the yarn hooking in the first course is surely performed, and the above-mentioned drawbacks are solved.

Here, of the knitting needles on the standby position side (hereinafter referred to as the "standby position side knitting needles") of the knitting needles for performing the knitting operation on the knitting yarn whose tip is captured by the gripper, a predetermined one to be operated. Some knitting needles in position are determined as follows. First, of the predetermined knitting needles, for the knitting needle located closest to the standby position of the yarn feeder, a knitting needle that is close to the gripper so that the knitting yarn connected to the yarn feeder can be withdrawn from the gripper is selected. Further, of the predetermined knitting needles, the knitting needle located closest to the knitting operation side is such that the knitting needle connected to the yarn feeder from the knitting needle outside the knitting region located closest to the knitting operation side can be drawn by the knitting needle at the knitting operation position. First, a knitting needle close to the knitting needle at the knitting operation position is selected.

If the above conditions are satisfied, only one of the knitting needles on the standby position side may be set as a predetermined knitting needle, or a predetermined number of knitting needles may be set in place, or either one side may be set. One half may be a predetermined knitting needle.

The first course is the first course at the time of knitting. At this time, the knitting needle on the standby position side is
A knitting needle located on the standby position side of the yarn feeder from the knitting edge, that is, a knitting needle outside the knitting region on the standby position side of the knitting region, and when using multiple colors, the first course (knitting of a certain knitting yarn from the standby state (knitting) At this time, the knitting needle on the standby position side is the knitting needle located on the standby position side of the yarn feeder than the knitting needle performing the knitting operation for a certain knitting yarn. In the case of using multiple colors, the knitting needle on the standby position side of the yarn feeder from the knitting edge is not always the target, in other words, the knitting needle other than the standby position side of the yarn feeder on the knitting region may be the target.

When the distance from the knitting yarn gripping device to the knitting needle that hooks the knitting yarn first is large in the first course, the knitting yarn continuing from the gripping device to the yarn feeder is higher than when the distance is short. It passes through a position, that is, a position away from the knitting needle. However, in the first course of the present invention, all the knitting needles on the standby position side or a part of the knitting needles on the predetermined position operate to hook the knitting yarns, so the knitting needles in the knitting operation position are the knitting needles on the standby position side. From that, the knitting yarns that are connected to the yarn feeder will be hooked.

Since the knitting yarn extending from the knitting needle on the standby position side to the yarn feeder has the same height as that of the knitting yarn in the normal knitting operation, the knitting needle in the knitting operation position can surely hook the yarn. As a result, the knitting yarn can be reliably hooked on the knitting needle performing the knitting operation even if the distance is large.

[0013]

Example 1 In this example, knitting needles outside the knitting area on the standby position side of the yarn feeder rather than the knitting area were used as knitting needles on the standby position side. In the first course, the predetermined knitting needle is operated to hook the knitting yarn, and then, for example, in the second course, the knitting yarn is removed from the predetermined knitting needle.

1 and 2 show the overall structure. The knitting yarn 1 is supplied from the yarn package 2, passes through the side tension mechanism 3, reaches the yarn feeder 4, and is caught by the gripper 5 at the tip portion. At the time of knitting, the yarn feeder 4 moves in the direction of the arrow together with the traveling table 18 so that a large number of knitting needles 8 along the front needle bed 6 or the rear needle bed 7 and a large number of the needle beds 6 and 7 between them. Setting needle 9
Guide to the action area.

A large number of knitting needles 8 are arranged between the sinkers 10 in a state orthogonal to the moving direction of the yarn feeder 4, and each of them is driven in the advancing and retracting direction by an actuator 11 as in the invention of Japanese Patent Publication No. 12855. It is supposed to be done. After the knitting, the knitting yarn 1 can be cut by the cutter 12 near the gripper 5.

FIG. 3 shows a drive control system for the knitting needle 8. The actuator 11 of each knitting needle 8 is controlled by a knitting design computer 13 and a first controller 14, and one or more yarn feeders 4 are driven by a linear motor 17 and a second controller 15 is provided. And is controlled by the third controller 16. The knitting design computer 13, the first controller 14, the second controller 15, and the third controller 16 interlock with each other based on the knitting pattern to control the advancing / retreating movement of the knitting needle 8 and the reciprocating movement of the yarn feeder 4.

In the internal storage section of the first controller 14, operation patterns of all the knitting needles 8 in the knitting area are set for each knitting course based on a predetermined knitting plan. Here, the operation pattern is movement position data when the knitting needle 8 moves back and forth. As shown in FIG. 4, the operation pattern is a mountain shape having the height of the position H1 on the advancing direction side with respect to the yarn feeding position and its advancing direction and the position H on the rear side in the advancing direction.
2, H3 and H4 are formed.

The knitting area is, as shown in FIG. 5, a needle bed 6,
7 is set in the approximate center, but outside the knitting region on the standby position side of the yarn feeder 4, a part of the predetermined position, that is, N for every two yarns is placed.
o. First corresponding to 1, 2, 3, 4, 5, 6 knitting needles 8
The operation pattern data is also input to the storage unit of the controller 14. The data input therein is only the operation patterns in the first course and the second course of designing.

Data of the reciprocating motion width of each traveling course of the traveling table 18 to which the yarn feeder 4 is attached and the speed pattern of the traveling table 18 are input to a storage section inside the second controller 15. Then, in the storage section inside the third controller 16, the knitting needles 8 to be operated depending on the selection of the traveling platform 18 to be traveled for each knitting course and the position of the yarn feeder 4.
The data for selecting and has been entered.

The third controller 16 synchronizes with the operation of the second controller 15 that controls the position of the yarn feeder 4 and the first controller 14 that controls the position of the knitting needle 8
Providing operation timing signals. On the other hand, every time the yarn feeder 4 passes over the knitting needle 8, the third controller 16 outputs an operation timing signal to the first controller 14 of the knitting needle 8 to be operated, based on the operation pattern.

For example, in the first course of designing,
As shown in FIG. When the knitting needle 8 on the left side of the knitting needle 8 of No. 4 is opposed to the knitting needle 8, the third controller 16 determines The first controller 14 for controlling the movement position of the knitting needle 8 of No. 6 outputs an operation timing signal so as to move the position of the top end of the knitting needle 8 toward the position of H1, and
No. The position of the top end of the knitting needle 8 is set to H4 with respect to the first controller 14 which controls the moving position of the knitting needle 8 of No. 3
The operation timing signal is output so as to move to the position of No. First for controlling the moving position of the second knitting needle 8
An operation timing signal is output to the controller 14 so as to move the position of the top end of the knitting needle 8 to the position of H3. In addition, No. The knitting needle 8 of No. 1 has a position H1.
→ H2 → H4 → H3, where the knitting yarn 1 is held and stopped.

In this way, in the first course of the knitting, the No. The knitting needles 1 to 6 are shown in FIG.
It operates based on the operation pattern indicated by the chain double-dashed line. In this process, each knitting needle 8 hooks the knitting yarn 1 when retreating from the position H2 to H4. At this time, from the gripper 5 to N
o. Since the distance to the knitting needle 8 of No. 1 is short, No. 1 The knitting needle 8 of No. 1 reliably hooks the knitting yarn 1 connected to the yarn feeder 4 from the gripper 5, and the other No. The knitting needles 2 to 6 also hook the knitting yarn 1 in sequence.

After that, as shown in FIG. Although the knitting yarn 1 which is continuous from the knitting needle 8 of 6 to the yarn feeder 4 is hooked, the position of the knitting yarn 1 is
Since the height is the same as that during the normal knitting operation, the knitting needle 8 in the knitting region can reliably catch the knitting yarn 1. After the completion of the first course, the setting needle 9 is moved to the position shown in FIG.
It descends all at once like (3). In the second course,
The predetermined knitting needle 8 reciprocates again as shown in FIG. 2 (4) to remove the knitting yarn 1. afterwards,
The knitting yarn 1 is cut by the cutter 12 between the gripper 5 and the needle beds 6, 7.

7 and 8 show a conventional example.
As shown in FIG. 7, when the knitting region is close to the gripper 5, the crossing amount of the knitting yarn 1 and the knitting needle 8 can be sufficiently large in the first course. On the other hand, as the knitting area moves away from the gripper 5 as shown in FIG.
The amount of intersection with is small. Since the crossing amount is small, the knitting needle 8 cannot reliably hook the knitting yarn 1 in the knitting region.

However, in the present invention, as shown in FIG. Since the knitting needles 1 to 6 draw in the knitting yarn 1, the amount of intersection between the knitting needle 8 and the knitting yarn 1 can be sufficiently large during the drawing operation of the knitting needle 8 in the knitting region.

[0026]

Example 2

In the case of the flat knitting machine of the type in which the reciprocating motion of the knitting needles 8 is performed by the carriage, the predetermined knitting needles 8 outside the knitting region perform the same operation as in the first embodiment in the first and second courses of knitting. A signal may be output to the needle selection device built in the carriage.

[0028]

[Other Embodiments] The course of operating the knitting needles 8 on the standby position side of the yarn feeder 4 with respect to the knitting needles 8 in the knitting region, that is, outside the knitting region is not limited to the first course of knitting, and is used during knitting of multiple colors. The first course from the state where the tip of a certain knitting yarn 1 is captured by the gripper 4 may be used. At this time, the target knitting needle 8 is the knitting needle 9 outside the knitting region.
Not limited to this, the knitting needle 8 is located closer to the standby position of the yarn feeder 4 than the knitting needle 8 where the certain knitting yarn 1 is knitted. Of course, the knitting yarn 1 hung on the knitting needle 8 is stitched out in a predetermined course after the second course.

[0029]

According to the present invention, the knitting yarn can be reliably caught even if the distance from the gripper to the knitting needle at the knitting operation position is large. Therefore, (1) a narrow knitted fabric can be knitted at a position where the center of the knitted fabric coincides with the center of the flat knitting machine, so that the pulling down force acts uniformly and the knitting is stable.
The effect is that the stitches are even, and (2) knitting operations using multiple colors can be performed stably.
