(effect) The operation of the present invention will be explained.

When using the Lilyan knitting machine according to the present invention, first, the yarn that will become the core yarn supplied from the tension mechanism (not shown) above the base frame is transferred to the core yarn guide piece, and the yarn that will become the filament is placed on the yarn feeding bar. The threads are passed through the thread guide pieces, passed through the knitting needles, passed through the thread feed hole of the rotating part, and installed into the thread winding mechanism below the base frame. At this time, the yarn that will become the filament is supplied to the knitting needles from the yarn guide piece of the yarn feed bar to form the filament. The length of this filament corresponds to the depth of the cut groove of the rotating part, and the deeper the cut groove, the shorter the length of the filament.

In addition, when not performing filament processing, the thread feeding bar is moved to prevent the thread that is to become a filament passed through the thread guide piece of the thread feeding bar from being supplied to the knitting needle, so that the thread that is to become a filament is The yarn to become the filament is knitted inside the core yarn by being directly supplied to the yarn feeding hole of the rotating part.

Further, while rotating the rotating section, the thread winding mechanism is also rotated at a slightly slower speed in the same direction as the rotating section. At this time, the knitting needles move up and down along the axis of the rotating part in response to the inclination in the inclined annular groove formed by the pair of supports, and appropriately knit the yarn supplied from above to form the base frame. It is transported to the thread winding mechanism below. In addition, when the knitting needles descend, the support piece rotates and comes into contact with the hook of the knitting needle, preventing the thread from being pulled out, and when the knitting needle moves up, the support piece is separated from the hook by the thread, and the support piece It rotates downward due to its weight, making it easier to pull out the thread.

In addition, the yarn fed to the knitting needles at the highest position is
By the time the knitting needle rotates to the highest position again, it moves to the lower part of the rotation fulcrum of the hook, and when the knitting needle moves to the lowest position, it is detached and fed into the yarn feeding hole of the rotating part.

In addition, by providing a blade on the outer surface of the knitting needle to which the filament is supplied, passing one of the cut grooves of the rotating part into the thread feeding hole, and installing the knitting needle provided with the blade in this cut groove, You can cut the end of the loop of filament thread. At this time, by passing the cut groove into which the knitting needle equipped with the blade is attached to the thread feeding hole, the filament can be cut with the filament fully knitted into the core yarn, thereby preventing the filament from slipping out of the lily yarn. It can be prevented.

In addition, by increasing the number of thread feeding bars, supplying threads of different colors to the thread guide piece of each thread feeding bar, and moving each thread feeding bar forward and backward separately, a wide variety of filaments can be applied to Lilian. can do.

Note that it is also possible to form a loop by hanging the yarn that will become the filament around two pairs of knitting needles 13. Furthermore, by moving the thread guide piece 14, it is also possible to knit Lilian by threading the thread that will become the core thread and the thread that will become the filament yarn on the same knitting needle 13.

As shown in FIG. 5, the Lilian knitting machine 1 of this embodiment can produce a Lilian R having loop-shaped filaments Y at required locations. The length of the filament Y can be easily changed by changing the depth of the cut groove 7 of the rotating part 8, and the formation interval of the filament Y can be easily changed by changing the advance and retreat time of the yarn feeding bar 15. can be changed to .

Furthermore, by adjusting the installation positions of the pair of supports 2 within the ring body 4, various knitting needles 13 having different lengths can be used.

FIG. 4 also shows another embodiment of the knitting needle 13a.

The knitting needle 13a of this embodiment has a blade 20 provided on the outer surface of the needle body 9 from the center to the proximal end, and when in use, the blade 20 is inserted through the thread feeding hole 5 of the rotating part 8 of the previous embodiment. It is installed in the cut groove 7 and is installed so as to be exposed outside the cut groove 7.

By using the knitting needle 13a of this embodiment, the sixth
As shown in the figure, it is possible to obtain a lilyyan r having filaments y whose loop-shaped tips are cut at required locations. The length of the filament y can be easily changed by changing the depth of the cut groove 7 of the rotating part 8, and the interval at which the filament y is formed can be easily changed by changing the advance and retreat time of the yarn feeding bar 15. can be changed to .

In this embodiment, two yarn feeding bars 15 are used, but three or more or one yarn feeding bar may be used.

In addition, one of the notch grooves 7 is made to pass through one of the thread feeding holes 5, but if the tip of the filament Y of Lilyan r is not to be cut, it is not necessary to make one of the notches 7 pass through the thread feeding hole 5. .

Further, although the core yarn guide piece 17 is provided on the upper edge of the ring body 4, it may be provided on the upper edge of the support body 2, the base frame 18, etc.

(Effects of the invention) According to the Lilyan knitting machine of the invention, the rotating part through which the knitting needles move up and down is rotated in the horizontal direction, and the yarn is not directly supplied from the tension mechanism as in the past, but from the yarn feed bar. By rotating the yarn winding mechanism horizontally in the same direction as the rotating section, the knitted lilyan strands can be wound up as they are, and the knitting needles can be raised and lowered. Since the rotating part is rotated, productivity is improved without being limited by the number of rotations, and a lilyyan having loop-shaped filaments at required locations can be obtained.

By using multiple thread feeding bars, supplying threads of different colors to each thread feeding bar, and moving each thread feeding bar forward and backward separately, it is possible to obtain a lilyan using multicolored filaments. .

In addition, by providing a blade on the outer surface of the knitting needle, passing one of the notch grooves of the rotating body through the thread feeding hole, and attaching the knitting needle with the blade in the notch groove passed through the thread feeding hole. , it is possible to obtain a lilyyan with loop-shaped truncated filaments.

Therefore, it is very useful for expanding applications.
