Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hand knitting machine equipped with a needle bed in which a large number of knitting needles are arranged in a row, and a carriage that slides on the needle bed.

In the conventional carriage, pattern knitting was performed by introducing the knitting needles at the needle selection position into the pattern knitting path, but in the present invention, in addition to the pattern knitting path (first pattern knitting path), a second pattern knitting path is provided. By introducing a part of the knitting needles at the needle selection position into the second pattern knitting path, the knitting yarn for coloring in the knitting of a varied and complex pattern, for example, two-color simultaneous knitting cotton, is combined with the knitting yarn of another color. The purpose of this is to make it possible to knit different patterns of the same type side by side.

Specific examples thereof will be explained below based on the drawings.

5c and the backward cam portion 25d are formed as appropriate.

Reference numeral 26 denotes a yarn opening fixed to the center of a knitting fabric presser foot 27 attached to the front of the carriage 1, and forms three yarn openings: a normal knitting yarn loss 6a, a first pattern knitting yarn 26b, and a second pattern knitting yarn opening 26c.

Further, knitting members such as a magnet 28 for opening the bellows are appropriately arranged near the yarn opening 26.

Therefore, the knitting needles at the knitting time position B are moved by one needle selection raising cam 1.
6, the yarn is moved forward by the main cam 4, is moved backward by the swing cam 11 of the backward cam portion 8a1, is fed from the normal knitting yarn opening 26a, and is fed to the other tuck cam 7' and the main cam 4.
If the switching cam 21 is in the horizontal position and the opening/closing cam 14 is in the rear position, the knitting needle at the needle selection position C passes through the normal knitting path (shown by the one-dot chain line in FIG. 1) and is moved back by the partition cam 20 The forward cam portion 20b1 is advanced by the opening/closing cam 14 and the first pattern knitting path forming cam 8, and is slightly retracted by the backward cam portion 9a. , passes through the first pattern knitting path (shown by the two-dot chain line in FIG. 1) that is retracted by the retracting cam portion 8'a1 swing cam 11' and the main cam 4', and when the switching cam 21 is in the inclined position, The switching cam 21 is moved forward by the second pattern knitting path forming cam 9, and is fed from the second pattern knitting yarn roller 26c. It passes through the second pattern knitting path (indicated by broken lines in FIG. 1) which is retracted by the 'a1 swing cam 11' and the main cam 4'.

Note that the second pattern knitting path is a narrow pulling path, that is, the other plate cam 1.
3' is retracted upward, and the knitting needles are introduced in front of the other second pattern knitting path-shaped cam γ without feeding yarn from the second pattern knitting yarn row 26c, and the carriage 1 is moved while maintaining that position. You can make them take a path outside.

The action of the above-mentioned tapping configuration will be explained.

First, when the carriage 1 moves in the direction of the arrow A, the knitting needles after knitting are moved by the needle selection raising cam 16, the needle folding lower cam 18, the needle selection device provided on the needle bed 3, the selection cam 19, the backward cam section 20a, etc. By the cooperative action, the needles are sorted and arranged at the knitting time position B and the needle selection position C in a desired needle selection manner.

Next, during the knitting at the needle selection position C, the knitting needle (the knitting needle in section T in Fig. 4) is about to be introduced into the second pattern knitting path (indicated by the broken line in Fig. 1).
Corresponding to this, the indicator member 25 is fixed by fitting the protrusion 25b into the rear part of the needle groove 3a of the needle bed 3.

Thereafter, when the carriage 1 is slid in the direction opposite to the arrow A, the knitting needles at the knitting time position B pass through the normal knitting passage (indicated by the dashed line in FIG. 1) and are fed from the normal knitting yarn opening 26a.
It becomes the ground group for stockinette knitting and the needles for the next stage are selected.

Also, regarding the knitting needles at needle selection position C, connecting plate 2 of carriage 1
Until the pin 23a of No. 3 engages with the retracting cam portion 25d of the cam groove 25a of the indicator member 25, the switching cam 21 is placed in the horizontal position (shown by the two-dot chain line in FIGS. 1 and 2), and therefore the selected The knitting needles at needle position C pass through the first pattern knitting path (indicated by the two-dot chain line in FIG. 1), are fed from the first pattern knitting yarn loop 26b, and
The color scheme of the cotton will be selected and the needles will be selected for the next stage.

Next, when the pin 23a of the connecting plate 23 engages with the retreating cam portion 25d of the indicating member 25 and moves backward against the spring 24, the switching cam 21 is also moved to the tilted position (see FIGS. 1 and 2). The knitting needles pass through the second pattern knitting path (indicated by broken lines in FIG. 1).

Therefore, the yarn is fed from the second pattern knitting yarn row 26c to form a second coloring line different from the "th" coloring line, and needles are selected for the next stage.

When the carriage 1 advances further and the tip of the switching cam 21 passes through section T in FIG.
5c, the switching cam 21 also moves to the horizontal position,
Thereafter, the knitting needles pass through the first pattern knitting path (indicated by the two-dot chain line in FIG. 1).

Therefore, only the knitting needles in the section T in FIG. 4 have the same pattern, but the coloring lines are different from the coloring lines in the other sections.

Thereafter, by sliding the carriage 1 in the direction of arrow A, a pattern can be knitted in the same manner.

In the present description, the T section in FIG. 4 has been explained using an example of a knitting method in which only the color scheme is different, but the T section can also be knitted in other patterns, for example, pulled up knitting.

As is clear from the above explanation, the hand knitting machine of the present invention introduces a part of the knitting needles at the needle selection position into the second pattern knitting path by simply sliding the carriage, and introduces the other knitting needles into the first pattern knitting path. Therefore, it can be introduced into the pattern knitting path, so it can be used to knit complex patterns that are rich in variety. For example, in a two-color simultaneous knitting line, the color-matching knitting yarn is replaced with a knitting yarn of another color to knit different-colored patterns in the same type side by side. be able to.
