Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of knitting a glove opening knitting part, and relates to a method for knitting a glove opening part in the middle of knitting in a glove which is knitted into a bag shape using a flat knitting machine having a pair of flat needle beds with the tops facing each other in a chevron shape. , when switching the thread used for knitting,
The present invention is characterized in that the yarn ends of both the old and new yarns can be drawn into or knitted into the knitted fabric structure so that the yarn ends do not protrude into or out of the bag-shaped glove.

When knitting gloves, the yarn used is changed during knitting in order to create a pattern. In this case, the replaced old yarn is left extended in the course direction on the back side of the knitted fabric (on the inside of the glove), or the end of the yarn is cut off when knitting is finished. However, when the yarn ends are cut, the yarn ends remain outside the knitted fabric, so it takes time and effort to manually pull them into the knitted fabric to increase the commercial value.

The same yarn end treatment as described above is also performed when changing the yarn when knitting the opening part using a yarn different from the yarn used for knitting the glove body.

The purpose of the method of the present invention is to automatically perform yarn end treatment when switching the yarn used as described above, and to knit the yarn ends into a knitted fabric.

In the method of the present invention, when switching the main yarn used for knitting the glove body, the end of the main yarn is controlled by a pressurized air flow to control the approach trajectory of the auxiliary yarn to be fed for the next course knitting. The yarn end of the auxiliary yarn that knits the glove opening part is blown up inside, and the yarn end of the auxiliary yarn that knits the glove opening part uses the elasticity of the elastic yarn guide that is in pressure contact with the yarn, and the yarn is blown up by the repulsion when the stretched yarn is cut. The yarn end is introduced into the locus of the yarn to be fed for the next course knitting, and is knitted together with the yarn of the next course knitting.

Next, the method of the present invention will be explained.

Knitting of the glove begins with the front needle bed 21 from the tip of the little finger pocket, and after knitting the little finger pouch, knitting of the four fingers is completed in that order of ring finger, middle finger, upper part of the palm, thumb, lower part of the palm part, and so on. The wrist part and mouth knitting part are knitted, but when knitting the little finger and toe pocket, only the required number of knitting needles used for the knitting are raised to the working position, and the others are lowered to the rest position, and the main yarn end processing device 1 is moved. Move it to the right until it is close to the little finger knitting needle (not shown) in the operating position. This operation is performed by pushing the conduit 16 to the right by a mechanism not shown, thereby moving the looper block 5 to the looper block guide shaft 3,
4.Slide on the top. Then, the knitting of the little finger tip begins, and after knitting the little finger pouch, the ring finger, middle finger, and index finger are knitted in this order. When knitting of one finger pouch is completed, the looper block 5 is moved to the needle width for knitting the next finger pouch. 1, and begins knitting the next finger bag. This movement to the left is effected by pulling the conduit 16 provided in the looper block 5 to the left. When knitting one finger bag is completed and the next finger bag is to be knitted, the procedure is as follows.

When the knitting of one finger bag is completed, the main thread carrier 61 is at the left side position of the needle bed as shown in FIG. A main thread 60 is passed between the course and a main thread carrier 61. In this state, the looper 7 rises, locks the main thread 60 with the hook 17 at the tip, and descends, so the main thread 60 is bent into a V-shape and a part of it is bent into the open fixed scissors 10. The main thread 60 is inserted between the movable scissors 11 and subsequently closed by the movable scissors 11, and the thread end connected to the main thread carrier 61 is nipped between the movable scissors 11 and the thread presser plate 12. Ru. The scissors are opened and closed by rotating the movable scissors support shaft 19 via the crank 18 by rotating the looper block guide shaft 4 by a mechanism not shown. The yarn end connected to the cut finger bag is blown up by the air from the nozzle 8 ejected at this time, and when the main yarn is cut, the main yarn carrier 61 advances from the left side to the right side of the needle bed and feeds the yarn. Therefore, the main yarn end blown up by the air ejected from the nozzle 8 is attached to the yarn being fed, and the yarn end is knitted into the knitted fabric together with the main yarn from the main yarn carrier 61. In this way, the fingers, laces, and wrist portions are knitted continuously, and then the mouth knitting portion is knitted in several courses.

When the knitting of the wrist part is completed as described above, the main thread carrier 61 stops at the thumb side as shown in FIG. As shown, the main thread 60 is crossed. At this time, the looper 7 is lowered by a mechanism not shown, and the hook 17 at the tip engages the main thread 61 indicated by the dashed line and lowers, moving the main thread 61 to the first
It is bent into a V-shape as shown by the solid line in the figure, and a part thereof is inserted between the open fixed scissors 10 and movable scissors 11 of the scissors 6. Then, the rotation of the looper block guide shaft 4 rotates the movable scissors support shaft 19 via the crank 18, closing the movable scissors 11 and cutting the V-shaped main thread 60. The yarn end that is connected to the main yarn carrier 61 at the same time as cutting is nipped between the movable scissors 11 and the yarn presser plate 12. At this time, the cut thread end connected to the glove is attached to the glove 1 rather than the looper 7.
The air blown out from the nozzle 9 located on the 5 side blows up the air as shown by the two-dot chain line in FIG.

By the time the glove side yarn end is blown up, the auxiliary yarn carrier 62 has reached the left end of the glove while feeding the auxiliary yarn 63 for knitting the opening knitting edge of the wrist, and has cut the main yarn and aired. When the main thread is ejected, it reverses and moves to the right, but at this time, the blown up main thread end is attached to the auxiliary thread 62
At the same time, it is knitted into the opening part. The auxiliary yarn 62 used in the opening section is mainly an elastic yarn.

The auxiliary yarn carrier 62 is on standby on the little finger side, and knits appropriate courses, for example, about 3 courses, in each of the front and rear needle beds 21 and 22, including the weaving of the blown-up yarn ends of the main yarn 60 mentioned above. Finish organizing the opening section. When knitting of the opening section is started, the auxiliary yarn carrier 62 is located at the little finger side of the glove as shown in FIG. When knitting of the opening section using the auxiliary yarn is started, the ends of the auxiliary yarn 62 are treated as follows.

Before the auxiliary yarn 63 starts knitting the opening section, the auxiliary yarn carrier 62 is stopped above the auxiliary yarn end processing device 2 on the little finger side.

At this time, the auxiliary thread carrier 62 and the auxiliary thread scissors 25
An auxiliary thread 63 extends between them. The end of the auxiliary thread 63 is nipped between the movable blade 36 of the auxiliary thread scissors 25 and the protrusion 47 of the auxiliary thread presser plate 42, and as the auxiliary thread carrier 62 moves toward the thumb side, the auxiliary thread moves toward the front surface. Needle of side needle bed 21 (not shown)
The yarn end of the auxiliary yarn 63 crosses between the glove 15 and the auxiliary yarn pressing plate 42 as shown in FIG. The end of this yarn is connected to the upper surface of the movable blade 36 and the protrusion 4 of the auxiliary yarn presser plate 42 as described above.
The threads connected to the knitted fabric of the glove extend from the sloped part 49 of the yarn guide plate 44 to the upper surface of the protruding part 48 to reach the knitted fabric. As is clear from FIG. 1, the protruding part 48 of the yarn guide plate 44 is at the highest position of the threads between them, and the auxiliary thread 63 is bent in an "H" shape with the protruding part 48 at the top. Since the protruding portion 48 has elasticity, the auxiliary thread 63 in this portion receives an upward repulsive force from the protruding portion 48 . Then, when the auxiliary yarn carrier 62 makes one reciprocation and starts moving to the left again to feed the yarn to the needle of the front needle bed 21, the wire 56 is pulled by a mechanism (not shown) and the auxiliary yarn scissors sliding plate 31 is moved as shown in FIG. It slides to the right in FIG. As a result, the auxiliary thread scissors 2 have the cam follower 37 fitted into the groove cam 35 of the auxiliary thread scissors sliding plate 31.
The movable blade 36 of No. 5 rotates clockwise in FIG. 3 about the screw shaft 40 to open the blade. As a result, the upper surface of the movable blade 36 and the protrusion 47 of the auxiliary thread presser plate 42
Since the contact between the lower surfaces is broken, the end of the auxiliary yarn that has been nipped at this portion is released, and at the same time, the end of the yarn is repelled upward by the elasticity of the protrusion 48 of the yarn guide plate 44. Further, if an elastic yarn is used as the auxiliary yarn 63, its repulsive force will be further increased and the yarn end will fly in the direction of the glove opening knitting part. For this reason, the flying yarn end becomes entangled with the auxiliary yarn 63 from the auxiliary yarn carrier 62 running to the left for knitting the second course of the opening section by the front needle bed 21. Therefore, when the auxiliary yarn is fed to the front needle bed 21, the yarn end is also knitted at the same time, and the yarn end does not protrude outside the knitted fabric.

The knitting of the opening knitting part where the yarn ends at the beginning of knitting are treated as described above is performed by knitting the auxiliary yarn carrier 6 after knitting several courses.
The process ends when the thread 2 reaches the auxiliary thread end processing device 2 on the little finger side. Then, by further pulling the wire 56, the auxiliary thread scissors sliding plate 31 moves to the right, and the cam follower 37 moves within the groove cam 35, causing the movable blade 36 to move.
, and at the same time the cam follower 5 in the cam groove 55 due to the movement of the looper drive cam 54.
2 raises the looper 51 and raises the hook 54 higher than the auxiliary thread 63 extending from the auxiliary thread carrier 62 to the glove 15, as shown in FIG. Next, when the tension on the wire 58 is released, the auxiliary thread scissors sliding plate 31 moves to the left by the contraction force of the spring 34, rotates the looper 51 counterclockwise, and the hook 54 moves the auxiliary thread carrier 62.
and the auxiliary thread 63 connected to the little finger side of the opening part of the glove 15
Lock it and pull it down into a V-shape and remove a part of it with the auxiliary thread scissors 2.
5 into the opening between the movable blade 36 and the fixed blade 38. In this state, when the auxiliary thread scissors sliding plate 31 moves further to the left, the movable blade of the auxiliary thread scissors 25 closes and the auxiliary thread 62
At the same time as the auxiliary thread carrier 62 is cut, the end of the cut thread that is connected to the auxiliary thread carrier 62 is nipped between the upper surface of the movable blade 36 and the lower surface of the protrusion 47 of the auxiliary thread presser plate 42. Further, the thread end connected to the little finger side of the opening knitting part is released from the tension by the hook 54 at the same time as cutting, and therefore rebounds toward the glove side.

Later, when the auxiliary yarn is a heat-shrinkable yarn, this final yarn end is shrunk by heat treatment to shrink the opening knitting part, and the yarn end is buried in the shrunken knitted fabric.

As detailed above, in the method of the present invention, even when the yarn is switched during knitting using the main yarn to knit the opening section, the yarn is fed from the carrier in order to blow up the yarn end at a position closer to the glove than the looper. The yarn end can be easily attached to the yarn being threaded, the yarn end can be neatly knitted into the knitted fabric, and when the yarn extending from the nipped point to the knitted fabric comes into pressure contact with the yarn guide plate, The elasticity of the yarn guide plate allows the yarn end with the nip released to fly in the direction of the knitted fabric, so there is no need to provide an air blowing mechanism to make the yarn end fly, and the yarn can be easily fed for next course knitting. The flying yarn ends can be added to the yarn being changed, and gloves can be automatically knitted in which the yarn ends when the yarn is switched are knitted into the knitted fabric.
