Description

[Detailed Description of the Invention] This invention relates to an improved double circle = m yarn feeder, especially to the individual yarn feeders. This invention relates to a double circular knitting machine that can change the texture of the fabric by separately changing the timing of the needles used in the double circular knitting machine, and allows the development of a new set of irons.

For double circles = m, the needle timing is adjusted to make the loops even and to reduce scratches due to dropped stitches and thread breakage, as well as to adjust the texture. As shown in Figure 6, there are four types of timing methods (
In the diagram, (1) is a cylinder needle, (3) is a dial needle, and K
s indicates the knitting point on the cylinder side, Kd indicates the knitting point on the dial side, and the arrow indicates the rotation direction of the cylinder.)

m is the regular timing in which the dial side compiling point qKd is behind the cylinder side compiling point Kc. [In the old case, the synchronized timing is the same for both cities, [I11] is the cylinder side compiling point Kc is delayed. The reverse timing [1v] is a reversible timing that has a large delay of Kd to the dial side configuration.

Special feature: With the reversible timing described in [■] above, the cylinder needle moves to the knockover position extremely quickly compared to the dial needle, and as a result, a chevron-shaped loop is formed by the hook of the cylinder needle and the dial needle. . At this time, the timing of the dial needle is delayed, so the loop cannot be on the dial needle's tongue, and when the dial needle descends, the thread (first thread) and) force are not applied to the hook and the rubber knitting occurs. +r
4nf i cannot be cut, and by supplying a thread (second thread) with a different dial needle number at the time-feed system in this state, a single-sided tuck structure is knitted with the first thread. Said second number, Koyori Hira~Gumi, is exposed to copper acid. In this way, it is possible to add changes to the braid diagonal by reversible timing.

In the conventional double circular knitting machine, the entire cam box +51 on the tile side is rotated to swing it from side to side to obtain one of the four timings.

The cam box +51 is provided with a clear cam (2) and a switch cam (4) corresponding to each yarn feeder, and a guide cam (6) is provided for the switch cams (t411411) of the two adjacent yarn feeders. All of these cam groups were fixed to the cam box (5) and could only be adjusted in the diametrical direction.

Therefore, for example, in the case of a steel machine with 24 yarn feeders, all 24 yarn feeders had the same timing number.

In view of the above-mentioned conventional technology, the present inventor independently adjusts the cam installed at each yarn feeder separately from the cam installed at the yarn feeder of the song, thereby freely adjusting the above four types of timing for each yarn feeder. I came up with the idea of taking it. This makes it possible to change the texture of the fabric by changing the timing of individual yarn feeders even when knitting fabrics with the same knitting pattern as before, and to change the texture of the fabric by changing the timing of individual yarn feeders.
Knit, tuck, welt 1i7ii'j with adjustment
The present invention aims to provide a circular knitting machine that can easily perform a new 41-weave opening by combining the above-mentioned four timings, and can quickly meet the current demands for diversification of surface finish.

Preferred implementation of this invention according to the drawings with missing numbers 5! Deaf correction [F] Vomit 3! Although Hayabusa will explain the ← cow ÷ method, it can also be applied to the 4 fixed method (cam rotation method).

In the actual example shown in Figures 1 to 5, the cam on the cylinder side is movable in the lateral direction, that is, in the circular direction, but the shaft head of the present invention is not limited to this, and is movable on the dial side. This includes cases in which the cams on both dial and cylinder sides are provided with position adjustment ports in the circumferential direction, and cases in which the cams on both the dial and cylinder sides are provided with position adjustment ports in the circumferential direction. It is something that
In Figures 1 to 5, 11 (1 is the cylinder, flll is the cylinder cam rail, and the back of the cam rail i +++ is a clear cam! 1211 The first is the ID cam ilυ
, a second guide cam 1181 is provided. A horizontal H-shaped clear cam position adjustment groove is provided at the location corresponding to the clear cam (121) on the cam rail (11). It consists of a vertical groove a, a horizontal groove, and a second vertical groove.The clear cam fixing screw T281 protruding from the front of the clear cam passes through the groove and protrudes to the outside of the cam rail (11j). ing.

It can be fixed by tightening the fixing screw (11! It is possible to over-adjust the fixing screw to the left and right by moving it to the appropriate position and tightening the head part 9).

flllo] t341 is a position adjustment groove provided for each of the first and second guide cams 1t18+,
Clear cam: Like the 12+, each has a protruding fixing screw βataa so that it can be positioned in the folded position in the vertical direction.

, +4'l (14') is a static cam, which is held by the holder (3~) via a holding screw (40) so as to be able to move vertically. (421 is a set screw, which is held by this number. The static cam α4 can be fixed at the desired position by bringing the screw ((l) to the desired position above and below and tightening the head part.

A long groove 1451 for moving the static cam is bored in the horizontal part 113) of the cam rail mountain in the circumferential direction. The horizontal legs 14 extending from the lower end of the reholder (3 to 3) are the fixing screws (46) that straddle this long groove (451) and hold them together.
This allows the static cam to be positioned at the desired position in the circumferential direction of the cylinder! 041 (14) have different shapes, and in particular, each lower edge Q51 (15') is designed so that the stroke and locus of the needle tip differ depending on the four timings mentioned above. It is formed.

In FIGS. 1 to 4, arrow A indicates the direction of rotation of the machine. The cams, cam rails, etc. shown in the figure do not rotate and are fixed.

Next, to explain the operation of the above embodiment, when regular timing (Fig. 1) is used, the clear cam (121 fixing screw (c) is in the middle of the first vertical groove, the The second guide cam (+e+ 18) is in the welt (sinking) position, and the second stitch cam (14) is in the position B where it crosses the long groove 141191 for moving the stitch cam.Therefore, the cylinder needle fi+ is in the clear cam (
Rising along the left hypotenuse of 121, Stisochicum 04)
It is possible to descend along the lower surface of the cylinder and obtain regular timing as shown in Fig. 1 [1].

When determining the synchronization timing, use Clear Cam! as shown in Figure 2. As with the case of 121 fixed screw ripeness or regular timing, the fth vertical groove (existed innocently,
The first guide cam (the first guide cam has been raised and is in the tuck position. Also, the stitch cam (14') has a long groove 4511cB and C
It is located at Therefore, due to the shape of the oblique side of the clear cam 1121 and the lower surface of the stitch cam (14),
It is Noh that requires synchronized timing. In this case, a stitch cam with a long stroke (14') is used, and its tar, ++'
The position of the cylinder → i knitting point Kc is delayed due to the clear cam (from 121 (1)), and both the cylinder side and the dial side are aligned. In this case, the first guide cam 116) It rises and prevents the cylinder needle (1) from coming down too quickly.
This prevents the feeding yarn from becoming sloppy and, furthermore, from being scratched by splashes.

When setting the reverse timing, as shown in Figure 3, use the clear cam (121 is also in the vertical groove, and the kite cam j
1614181 has risen to a tack position of 1d, but the stitch cam (14mm is different from the above case and has a length of J, 4mm).
5) When the cylinder needle is pushed further away to the position of D, the cylinder needle reaches the end of the cylinder with a further delay as shown in Figure 6 [11D] to enable reverse timing.

Corresponding to the further extension of the stroke of the cylinder needle (1) from rise D) to knitting KC, the second guide cam (9) also rises to the tuck position.

When performing reversible timing, as shown in FIG. (also long groove 145) Move to the left to position A and press -T on the cylinder needle]! 2G, Kc
Figure 6 [IV]
This enables reversible timing. In this case, the guide cam foal 1181 has sunk to the welt position.

In the above embodiment, (1) regular timing, reversible timing, and (2) synchronized tie and static cam (14') were used, but it is not difficult to use only the static cam (14) for all four types of timing. However, regarding synchronization timing and reverse timing, from the viewpoints of easy adjustment of yarn feeding and prevention of yarn feeding, etc.
It is more appropriate to use a static cam such as 14').

In the above embodiment, both the clear cam (121'OJ?) and static cam (14+ (14+) are aligned left and right!
I! , it was possible to locate the clear cam 021 in the vertical groove (support) position as shown in Figures 1 to 3, and then press the stitch cam! I4) Clear cam (12') only (14')
It is possible to obtain the timing of the three yuzus of a song, excluding the reversible timing, by separating them stepwise from the timing of the reversible timing. However, since all four types of timing are set separately for each yarn feeder and independently from the yarn feeder 1z, the clear cam (1z also has a clear cam (1z also has the left side, i.e. the second vertical groove, as shown in Figure 4).
”) is necessary.

Furthermore, the specific means such as the grooves that make each cam movable are not limited to those of the above embodiments.

Sarabanko, as described at the beginning, the position of the cam on the dial side may be adjustable in this way instead of the cam on the cylinder side for each yarn feeder (this position adjustment port).Also, the cam on the dial side, It is also possible to make the positions of both cams on the cylinder side adjustable to the left and right, and especially in this case, it is possible to reduce the movement of the cams on the dial side and the cylinder side, so there is no need to take one larger space between adjacent yarn feeders. This is very effective in that there is no need to reduce the number of yarn feeders in the knitting machine as a whole.

FIGS. 7 to 10 show cases in which the cam on the dial side is adjustable.

Guard cam (111) is guard cam (113) (115)
), but the position can be adjusted in the circumferential direction (arrow C), and at the appropriate position, the thick part (123) of the bisnitch cam (114) fits with the screw (127). ) is slidably housed in the cam box (105), and is in sliding contact with the guide cam (119) at the thin wall portion (125). The hole (129) into which the screw (127) is inserted is long and narrow in the circumferential direction of the dial box (105), and has a certain degree of width in the plate direction. Adjustment is possible in the direction of the arrow (b) in Fig. 7.

The clear cam (112) also has the same structure as the static cam (114), and its position can be adjusted in the directions of arrows (a) and (b).

In Fig. 7, the area ν has a static cam (1
14) shifts to the right, forming an arrangement for obtaining reversible timing (Fig. 6 [■]), and forming an arrangement for obtaining υ.

I-L-like G-Komoto's brother Akira selectively adjusts the timing of the double knitting machine to each yarn feeder by adjusting the timing of the cylinder cam P and/or dial cam to create a new Mi weave or a unique one. It is possible to easily knit a knitted fabric etc. having a texture of , and it completely eliminates the need for conventional timing adjustment/adjustment devices in which two yarn feeders have to be installed at all yarn feeders to ensure the same timing.
