Description

Detailed Description of the Invention This invention involves changing a plurality of yarn paths one after another in a relay race, and using the knitting yarns that are guided by these yarns that are different in color, quality, and composition, to produce a single piece of knitted fabric. In horizontal stockinette knitting machines that knit patterns, the knitting yarn can be reliably introduced into the hook of the knitting needle at the position where the yarn path is to be changed. To provide a yarn guide device in a horizontal stockinette knitting machine, which allows one knitting yarn of a course at the border of pattern knitting to pass horizontally under the knitting needle and play, thereby avoiding the formation of a compound color mixed raised course. The purpose is to

An embodiment of the structure of the present invention shown in the drawings will be described as follows.

1 is a rail horizontally suspended above the needle bed, 2 is a slider mounted on one side of the rail 1 so as to be freely movable, and 3 is a thread guide having a conductor hole 3a at its lower end. It is attached via a thread guide rod 5 to an elevating plate 4 which is attached to the slider 2 so as to be movable up and down. The lifting plate 4 is pulled up by a lifting spring 6, thereby keeping the lower end of the yarn path 3 in reciprocating motion at a position where it does not interfere with the movement of the knitting needles. 7 is a cam follower attached to the front of the upper end of the elevating plate;
This is placed on the line of movement of the thread guide push-down cam 8 provided on the lower surface of the carriage (not shown). The thread guide push-down cam 8, which is a thread guide push-down mechanism, has two substantially inverted trapezoidal cam acting portions 8a having the same shape and spaced apart from each other in the direction of movement of the carriage (not shown).
8a. Reference numerals 9 and 9 denote a pair of swinging pieces that are pivotally attached to both end portions of the side surfaces of the slider 2 at their base end portions and extend symmetrically in the running direction. These are kept in a predetermined position by the force of a tension spring 11 applied to the lower ends of hanging pieces 9a, 9a, which are integrally hung from the base ends of the swing pieces 9, 9. Further, each of the swinging pieces 9, 9 has a sloped part 9b, 9b that slopes diagonally upward at the tip, and a semicircular recess 9c, 9c is formed at the inner lower edge of the tip sloped part 9b, 9b, respectively. has been done. 10, 10 are stopper pieces, and swing pieces 9, 9
This prevents it from swinging downward from a predetermined position. 12 and 13 are a pair of opposing projections provided on the left and right sides of the upper surface of the slider 2; 14 and 15 are both projections 12;
These are recesses located inside each of the 13. 16,1
Reference numeral 7 denotes a restraining cam disposed on the left and right sides of the yarn path 3, which regulates the range of horizontal movement of the yarn path 3;
6 and 17 are attached to the rail 1 so as to be able to move left and right. These stopping cams 16 and 17 are connected to the thread path 3 and the rail 1.
It is connected and fixed to movable rods 18 and 19 arranged in parallel with the rail 1, respectively.
As these movable rods 18 and 19 move, they slide on the rail 1. 16a,1
Reference numeral 7a denotes connection pieces that connect the stop cams 16, 17 and the movable rods 18, 19, respectively. Locking rollers 20 and 21 are attached to approximately the center of the side surfaces of these connecting pieces 16a and 17a, and are large enough to fit into the recesses 9c and 9c of each swinging piece 9 and 9, respectively.

23 is a thread guide body attached to the top of a substantially inverted U-shaped support frame 24 in a carriage (not shown). Reference numeral 25 denotes a thread guide piece which can be raised and lowered freely and corresponds to the thread guide 3, and its lower end is connected to the protrusions 12 and 1 on the slider 2.
It is placed on the line of movement of No. 3.

In the above, the carriage (not shown) moves to the right in FIG. 1, and the thread guide piece 25 also moves in the same direction. When it reaches the stockinette knitting position, it is guided by the left oblique side of the left stop cam 16 and pushed up, and then fits into the recess 15 of the slider 2 and hangs on the right protrusion 13. The yarn path 3 then begins to supply the knitting yarn that it guides to the knitting needle row, and the yarn path index piece 25 moves the slider 2 provided with the yarn path 3 to the right. When the thread path 3 approaches the position where it alternates with another thread path (not shown), the tip inclined portion 9 of the right sliding piece 9 provided on the slider 2
However, the sliding piece 9 abuts against the locking roller 21 provided on the connecting piece 17a of the right stopping cam 17, and the sliding piece 9 swings. When the slider 2 further moves to the right and comes into contact with the stop cam 17, the recess 9 of the swinging piece 9 almost simultaneously
c is locked by the locking roller 21, thereby preventing the yarn path 3 from moving laterally. The thread guide piece 25 is guided by the left inclined surface of the stop cam 17 and comes off the protrusion 13. Next, the left cam action part 8a of the thread guide push-down cam 8 passes while pressing the upper surface of the cam follower 7 of the vertical moving plate 4, and during this time, the thread guide lower end of the thread guide 3 is raised and lowered by the thread guide push-down cam 8. It is pushed down below the plane of the needle row through the plate 4 and the thread guide rod 5, and is thrust into the front side in the direction of carriage movement of the knitting needle at a position where it alternates with another thread guide (not shown). The thread path 3 is secured at a position between the left and right knitting needles so that its lower end can be inserted accurately into the front side of the knitting needle at the position where the thread is to be exchanged. There will be no contact. Then, a loop is knitted with the knitting yarn being hung on a predetermined knitting needle. The replaced yarn path 3 (not shown) starts from the rear side of the same knitting needles mentioned above and knits the first loop with the knitting yarn fed to this yarn path. In this way, the patterned fabric is knitted while the thread paths 3 are sequentially alternated.

When knitting a tiered pattern, resting yarn path 3 after feeding the yarn to a predetermined section of the course at the border of the pattern
is indexed to the next yarn feeding position with its lower end pushed down below the knitting needle row surface. That is, when the slider 2 is in a state where its swinging piece 9 and the locking protrusion 20 or 21 are locked, the movable rod 18 or 19 moves the carriage to the left or right by the required distance of the stepped pattern. (not shown). Then, the upper surface of the cam follower 7 is pressed down by the cam action part 8a on the front side in the direction of travel of the thread path push-down cam 8 provided in the moving carriage (not shown), and the thread path 3 is pushed down. Move sideways in the same position. In this way, the lower end of the yarn guide of yarn path 3 keeps the knitting yarn under the back surface of the needle, and in this state, the knitting needles move forward and backward in sequence, so the fed knitting yarn is left to play horizontally. It becomes a floating thread.

Normally, the yarn path 3 that is at rest is pulled up by a spring 6 so as to keep its lower end at a position above the advancing limit of the knitting needles after the carriage (not shown) has passed, so that it does not become an obstacle to the advancing and retreating of the knitting needles. There is.

When the carriage (not shown) moves to the left, the symmetrical parts act to similarly knit a loop.

Note that there are two recesses 15 on the left and right sides of the top surface of the slider 2, into which the thread guide piece 25 is fitted when it is running to the right, and where the thread guide piece 25 is fitted when it is running to the left. One recess 14 is provided, and the lower end of the thread guide piece 25 is tightly fitted into the recesses 14 and 15. As a result, even if the machine vibrates during knitting, this will cause the slider 2 to
The yarn path 3 does not move independently from the yarn path 5, and the yarn path 3 always correctly feeds the yarn to the knitting needles.

As described in detail above, this invention is configured such that the lower end of the yarn guide of the yarn guide is formed in a shape that can protrude into the gap between the knitting needles of the row of knitting needles, and the yarn guide is formed in such a shape that it can protrude into the gap between the knitting needles of the knitting needle row. It is attached to the child so that it can be raised and lowered freely.
At the position where the knitting yarns are to be replaced, the lower end of the yarn guide of the yarn guide having the above-mentioned yarn guide holes is pushed down below the knitting needle row surface on the knitting needle side during the knitting yarn drawing process by the thread guide push-down mechanism provided in the carriage. The knitting yarn is knitted in this state, and the knitting yarn can be reliably introduced into the hook of the knitting needle at the position where the yarn path is to be changed.

Furthermore, when knitting a stepped pattern, for example, one of the knitting yarns of the course at the boundary of the pattern can be allowed to pass horizontally over the lower end of the knitting needle, thereby avoiding the formation of a complex mixed color raised course. The effect is that a smooth patterned knitted fabric without unevenness can be obtained.
