Description

[Detailed description of the invention] The present invention relates to a carriage for a hand knitting machine capable of simultaneous two-color knitting, and in particular, to a carriage for a hand knitting machine that is capable of knitting two colors at the same time. The knitting needles introduced between the intermediate partition wall and the knitting cam are guided to a portion of the partition wall substantially corresponding to the front side of the knitting cam, and the knitting needles are guided directly to the rear knitting path, and then moved forward to the front knitting path. The bat is characterized by being equipped with a bat course switching device that switches between a guiding state and a guiding state.

The object of the present invention is to switch between the butts of knitting needles to be introduced into the post-knitting path using the bat path switching device, thereby allowing knitting between normal two-color simultaneous knitting and knitting such as thread knitting using the pre-knitting path. The purpose is to allow for the implementation of these changes as appropriate.

An embodiment embodying the present invention will be described in detail below with reference to the accompanying drawings.

In the figure, 1 is a needle bed in which a large number of comb teeth 2 and knitting needles 3 are alternately arranged in rows.

4 in the figure is a carriage mounted on the needle bed so as to be able to slide from side to side, and is capable of making various knittings such as two-color simultaneous knitting, flat knitting, and thread knitting. Accordingly, the knitting cams that guide the butts of the knitting needles 3 are arranged symmetrically.

That is, in the figure, 5 is a front partition wall forming the front body needle passage, 6 is a rear partition wall forming a rear needle passage, and 7 is horizontally installed at two places on the left and right at the rear across the butt passage from the front partition wall 5. A pair of left and right intermediate partition walls, each having a notch opening 8 cut out in the middle part of the left and right sides, and an inner part of each notch opening 8 having an intermediate partition wall when the notch opening 8 is opened and closed. An opening/closing cam 9 is provided for advancing the butt of the knitting needle 3 introduced from the rear side of the knitting needle 7 toward the front side.

The opening/closing cam 9 and the notch opening 8 constitute a bat course switching device.

Reference numeral 10 denotes a pair of left and right knitting cams that are arranged at an angle at the rear across the bat passage from each of the intermediate partition walls, and each of the knitting cams has its front end facing the notch opening 8, and its rear end has a knitting cam that jumps forward. A raised auxiliary cam 11 is pivotally mounted.

12 is a central guide cam, 13 is a pair of left and right side guide cams,
14 is a pair of left and right sub-cams arranged in a substantially V-shape, 15 is a pair of left and right tuck cams, 16 is a pair of left and right forward swing cams, 17 is a pair of left and right backward swing cams, 18 is a pair of left and right switching cams, 19 are a pair of left and right pulling cams.

The front and rear swing cams 16 and 17 serve as front knitting path forming cams that guide the butt of the knitting needles introduced between the front partition wall 5 and one middle partition wall 7 to the other knitting cam 10. In addition, the rear swinging cam 17, the central guide cam 12, and the sub-cam 14 are connected to the one intermediate partition wall 7 and the knitting cam 10.
This constitutes a post-knitting path forming cam that guides the butt of the knitting needle introduced between the two knitting cams to the other knitting cam.

By arranging the switching cam 18 and the opening/closing cam 9 at the two-dot chain line positions using the above-mentioned cams, a front knitting path P1 and a back knitting path P2 for two-color simultaneous knitting are formed, and the switching cam 18 By arranging it at the solid line position, a guide passage P3 is formed on the rear side.

On both the left and right sides of the knitting cams, the butts of the knitting needles 3 after knitting are sorted back and forth, and the knitting preparation position A needle selection cam mechanism is provided that selects the needle position Y (the position where the stitch K is suspended above the open latch).

That is, in the figure, 20 is a forward cam that advances the butt of the knitting needle 3 to the front of the needle selection position Y, and 21 is a forward cam that presses down the butt of the knitting needle 3 in cooperation with a pattern extraction device (not shown) in the needle bed. A lowering cam that sorts the bats vertically; 22 is a sorting cam that sorts the bats sorted downward to the front and bats sorted upward to the knitting preparation position X at the rear; 23 selects the bats sorted forward. The sorting difference enlarging cam moves forward to position Y, and 24 is an auxiliary guide cam.

In the figure, reference numeral 25 denotes a support plate detachably supported by a pair of left and right tightening screws 26 at the front part of the carriage 4, and on the left and right sides of the lower surface thereof, a pair of left and right knitted fabric pressing plates 27 for suppressing the forward movement of the knitted fabric is provided. Fixed.

In the figure, reference numeral 28 denotes a yarn opening plate fixed to the lower surface of the left and right center of the support plate 25, and the lower plane part of the yarn opening plate 28 has the pre-knitting passage P1.
A front yarn opening 29 for supplying the knitting yarn T1 to the hook of the knitting needle 3 is provided, and a rear yarn opening 30 for supplying another knitting yarn T2 to the hook of the knitting needle 3 of the front and rear knitting passages P2.

In the figure, reference numeral 31 denotes a pair of left and right brush wheels for thread knitting, each of which is located at a position approximately corresponding to the front of the outer side of the knitting cam 7 at the open end of a mounting plate 32 fixed to the inner surface of the support plate 25. Pivotally mounted in a tilted position.

The brush on the circumferential surface pushes down the weft thread T previously placed over the knitting needles at the needle selection position Y, so that the portion between the knitting needles is disposed below the knitting needle sliding plane.

In the figure, reference numeral 33 denotes an auxiliary yarn opening for supplying the weft yarn T to the knitting needles 3 at the needle selection position Y, which is disposed at the top and front of the outer side of the left and right knitting fabric pressing plates 27, and whose base end is connected to the support plate 27. Fixed.

This embodiment is configured as described above.

Various organizing methods will be explained below.

For example, to explain two-color cotton at the same time, in advance, knitting needle 3
(This sorting may be done by a needle selection cam mechanism after the previous course has been knitted, or by a special needle selection device.)
, the opening/closing cam 9 and the switching cam 18 are arranged at the two-dot chain line position in FIG.
Insert I and T2 separately.

By sliding the carriage 4, the knitting needles at the circumferential positions
, P2, and knitting yarns Tl and T2 are separately supplied from corresponding yarn ports 29 and 30 on the way to knit stitches,
The butts of each knitting needle 3 are sorted into two new groups of front and rear patterns for knitting the next course, and are led out of the carriage.

Further, even if the carriage 4 is turned back and slid, the same operation as described above is performed.

Next, to explain thread knitting, the butts of the knitting needles 3 are sorted in advance at the circumferential positions X and Y, for example, one to one as shown in the figure, and the opening/closing cam 9 and the switching cam 18 are arranged at the solid line position. In addition, the knitting yarn T1 is inserted only through the front yarn opening 29, and the weft yarn T is provided at the auxiliary yarn opening 33.

Therefore, if the carriage 4 is slid, for example, in the direction of the arrow shown in FIG. The weft yarn T is fed into the hook No. 3.

After that, the knitting needle 3 at the needle selection position Y is advanced by the outer guide cam 13 to a position where the needle is almost completely removed, and then the knitting needle 3 is moved to the guide path P3.
At this time, the weft thread T lying on the knitting needle is pushed down by the brush wheel 31, and the part of the weft thread T that extends between the circular knitting needles 3 (the knitting needle 3 at the knitting preparation position
) is arranged below the knitting needle sliding plane (see Fig. 2), and the front part of the knitting needle at the knitting preparation position 7, therefore, the weft T is at the same position X,
It spans the front part of the Y knitting needle 3 in a vertical wave pattern (see Figures 1 and 2).

Then, the butts of the knitting needles 3 at the same positions X and Y join together and are moved forward in one motion by the rear surface of the rear knitting cam 10 and the opening/closing cam 9 to a considerably forward position and introduced into the front knitting path P1. .

At this time, the weft thread T is released from the brush wheel 31 and is restrained at a certain advancing position by the knitting presser plate 27, which is advanced as the knitting needles 3 advance, and is pulled away from the opened latch tip (Fig. 3). reference).

Thereafter, the butts of these knitting needles 3 are introduced into the pre-knitting path P1, and receive the knitting yarn T1 from the front yarn opening 29 midway through, and knit stitches using the knitting yarn T1.

After knitting, the butts of the knitting needles 3 are sorted forward and backward by a needle selection cam mechanism and led out to the outside of the carriage.

Through the above steps, the thread version of the course is created.

To make the next course of thread knitting, the weft T is hooked onto the auxiliary thread opening 33 on the opposite side, and the carriage 4 is turned back and slid.

Note that the weft T may not be supplied by the auxiliary thread port 33, but may be supplied manually before the carriage slides.

Furthermore, in the case of flat knitting, the switching cam 18 is placed at the solid line position and the opening/closing cam 9 is placed at the two-dot chain line position, so that the rear knitting path P2
and the backward clue 30, and furthermore,
In the case of tuck knitting, this can be done by a well-known method by flipping up the auxiliary cam 11 in the cam arrangement for flat knitting and placing the tuck cam 15 at the position shown by the two-dot chain line.

As described in detail above, the present invention provides a carriage capable of simultaneous two-color knitting, in particular, in front of the knitting cam in the left and right middle partition walls installed horizontally between the front partition wall and the left and right composition cams. A butt path switching device that can switch between a state in which the butt of the knitting needle introduced between the intermediate partition wall and the knitting cam is guided directly to the rear knitting path and a state in which it is guided forward to the front knitting path in a portion substantially corresponding to the knitting cam. With this, it is possible to carry out two-color simultaneous knitting using both the front and rear knitting paths and knitting such as thread knitting using only the front knitting path, alternately as appropriate.
