Description

DETAILED DESCRIPTION OF THE INVENTION In addition to ordinary rubber knitting in which knitting yarn is supplied to the knitting needles of the main needle bed and the knitting needles of the sub-needle bed, the present invention provides a method for knitting before and after the knitting needles of the main needle bed. So-called two-color simultaneous rubber knitting is performed by supplying a certain knitting yarn to the selected front knitting needles and the knitting yarn of the sub-needle bed, and supplying another knitting yarn to the rear knitting needles and the knitting needles of the sub-needle bed. The present invention relates to a double-disc type hand knitting machine that is capable of performing the following tasks.

Conventionally, in this type of hand knitting machine, as shown in Figs. 17 to 19, the sub-needle bed A is arranged in a row, and each knitting needle A is placed in front of the row line of the comb teeth on the main needle bed C. For example, Japanese Patent Application Laid-open No. 77648/1983 filed by the same applicant has proposed a method in which the two-color simultaneous rubber knitting is achieved by arranging the rubber knitting so as to be located at the same time.

When the two-color simultaneous rubber knitting is carried out using this existing proposal, as shown in FIGS. 17 to 18, the knitting yarn supplied to the rear knitting needle O1 of the main needle bed U When the force is drawn by the first hook of the rear knitting needle, the knitting yarn force is spread in a zigzag pattern between the first hook of the rear knitting needle and the knitting needle A of the sub-needle bed A under strong tension. The knitting force stretches or breaks the fibers, causing damage to the knitting force, and the knitting resistance increases, increasing the operating load on the carriage.
Because it is not supplied smoothly and in sufficient quantity to
There were drawbacks such as the stitches knitted using the knitting force were slightly smaller than the predetermined size.

However, the present invention makes it possible to eliminate all of the above-mentioned drawbacks, and also allows the sub-needle bed to be placed in a predetermined position extremely easily and reliably when switching from ordinary rubber knitting to two-color simultaneous rubber knitting or vice versa. This makes it possible to set the

Further, a protrusion 89 is provided at the rear open end of the punching protrusion 88 to raise the hook portion of the rear main knitting needle 5B so that the knitting yarn T2 is reliably captured by the hook. .

This embodiment is configured as described above. Therefore,
To perform normal rubber knitting, the sub needle bed 14 is placed in the normal position, the connecting piece 65 is fixed at the center of its movement, and both carriages 33 and 49 are connected so as to be able to slide together. In addition, the main knitting needles 5 are arranged so that those involved in knitting are placed in the knitting preparation position V, and those that take a break from knitting are placed in the rest position, and the sub-knitting needles 16 are used to place those involved in knitting in the knitting preparation position and the ones that take rest in the knitting preparation position V. The knitting yarn T2 is inserted into the rear yarn opening 72.

By sliding both carriages 33 and 49, rubber knitting can be performed according to a known method.

Next, to explain the two-color simultaneous rubber knitting, first, the sub needle bed 14 is placed in the retracted position as shown in FIGS. 2, 10, and 11, and the connecting piece 65 is moved freely. Both carriages 3
3 and 49 are connected so as to be relatively movable, and the front main knitting needles 5A and the back main knitting needles 5B are sorted and placed at the needle selection position W and the knitting preparation position V, and the sub knitting needles 16 are Place it in the formation preparation position.
Furthermore, knitting yarn T1,
Insert T2.

By sliding both carriages 33 and 49, the sub carriage 49 becomes the main carriage 33.
When these carriages 33 and 49 reach the knitting section, the butts of the front main knitting needles 5A move toward the front knitting path 44. The butt of the rear main knitting needle 5B is connected to the rear knitting passage 45, and the butt of the rear main knitting needle 5B is
When the butts of the knitting needles 5A, 5B, and 16 correspond to positions 1, 2, 3, 4, and 5 in FIGS. Each action shown in 1 to 5 is performed, and the front main knitting needle 5A carries the knitting yarn T1, the back main knitting needle 5B carries the knitting yarn T2, and the sub knitting needle 16 carries the knitting yarn T1.
1 and T2 are supplied to knit two-color simultaneous rubber knitting.

After this knitting, the front main knitting needle 5A and the back main knitting needle 5
The butts B merge together and are subjected to the action of the needle selection cam mechanism, and are sorted back and forth for the next course of two-color simultaneous rubber knitting, and are guided to the knitting preparation position V and the needle selection position W. On the other hand, all butts of the sub-knitting needles 16 are guided to the knitting preparation position.

Also, when both carriages 33, 49 are folded back and slid, two-color simultaneous rubber knitting can be performed in the same manner as described above.

In the case of this two-color simultaneous rubber knitting, especially the knitting yarn T
2 is fed to the rear main knitting needles 5B and the sub knitting needles 16 for knitting, as shown in FIGS. Since the knitting yarn T2 is not stretched in a zigzag manner between the two knitting needles 5B and 16, the knitting yarn T2 is not damaged, and is fed out extremely smoothly and lightly from the rear yarn opening 72 to the two knitting needles 5B and 16, and the stitches are knitted. This can be done easily, and stitches of a predetermined size can be knitted.

In this embodiment, in the case of simultaneous two-color rubber knitting, the auxiliary carriage 49 is arranged so that the pressing action of the knitting cam 52, which is always behind the main carriage 33 by the distance P, is slightly delayed from the pressing action of the main knitting cam 36. As shown in FIG. 16, the knitting yarn T1 can be supplied to the hook of the sub-knitting needle 16 extremely reliably. In other words, as shown in the figure, the rear main knitting needles 5B move back a little in advance, so that the hooks pull the knitting yarn T1 backward, and the knitting yarn T1
This is because the needles can be reliably placed within the descending locus of the hook of the sub-knitting needles 16. If both carriages 33, 4
9 in a normal rubber knitting state (a state in which the respective stepping ends of the left and right knitting main cams 36 and the left and right knitting cams 52 coincide in the left-right direction), as shown in FIG. 16, the rear main knitting needles 5B Since the retraction of the knitting yarn T1 is slightly delayed compared to the case of FIG. 16 and 3, the supply of the knitting yarn T1 to the hook of the sub-knitting needle 16 is somewhat less reliable. The 161st case is the case where the sub-needle bed 14 is placed in the normal position, and in this case, various drawbacks like the conventional one described at the beginning occur.

As described in detail above, the present invention is equipped with a device that allows the sub needle bed to be movable in the longitudinal and lateral directions relative to the main needle bed, and the main and sub needle beds are equipped with carriages mounted on the main and sub needle beds. Each of the front and rear knitting passages that guide the knitting needles of the needle bed, the knitting passage that guides the knitting needles of the sub-needle bed, the front yarn opening that supplies knitting yarn to each knitting needle of the front knitting passage and the knitting passage, the rear knitting passage and Targeted at double-disc hand knitting machines equipped with a rear yarn opening for supplying other knitting yarns to each knitting needle in a knitting path, the sub-needle bed is supported in a horizontally movable manner and is fixed to the main needle bed. A half-pitch lever is pivotably supported within a certain range on a mounting bracket that is attached to the mounting bracket, and one of the half-pitch lever and the mounting bracket is provided with a pin that protrudes toward the other, and the other is provided with a pin that protrudes toward the other. , a cam hole into which the pin is inserted and which moves the sub-needle bed laterally by 1/2 pitch of the knitting needle row by rotating the half-pitch lever from one rotational position to the other rotational position; Further, a fitting groove is provided in the vicinity of the half-pitch lever, the proximal end of which is removably fixed to the sub-needle bed, and which fits and holds the half-pitch lever at a predetermined position approximately in the middle of its rotation. By holding the half-pitch lever at the predetermined position by the holding metal fitting, the secondary needle bed is arranged at a position laterally moved by 1/4 pitch of the knitting needle row. This is what I did.

Therefore, if the sub-needle bed is placed in the normal forward position without using the half-pitch lever or the holding metal fitting, normal rubber knitting can be performed. By holding the sub-needle bed at a specific position approximately in the middle with a holding metal fitting and placing it in the rear retracted position, the knitting yarn at the rear yarn opening can be knitted with the knitting needles in the rear knitting path in two-color simultaneous rubber knitting. When the knitting yarn is fed to the knitting needles in the knitting channel to knit a stitch, the knitting yarn is wrapped approximately in a straight line over the knitting needles in the knitting channel, that is, the front side of the knitting needles in the sub-needle bed, and is zigzag between the knitting needles in both the knitting channels. Since the knitting yarn is not stretched over the knitting yarn, unlike the conventional method described at the beginning, the knitting yarn is not damaged, and a predetermined amount of the knitting yarn is extremely smoothly supplied to each knitting needle in the passage, making stitch knitting easier. Moreover, it is possible to knit stitches of a predetermined size.

Further, when switching from the normal rubber knitting to the two-color simultaneous rubber knitting, by holding the half-pitch lever at the specific position approximately in the middle of its rotation with a holding metal fitting, the sub-needle bed can be moved easily and easily. The sub needle bed can be reliably set and placed in the specified retreat position, and when switching from two-color simultaneous rubber knitting to normal rubber knitting, the sub needle bed can be easily returned to the normal position by releasing the action of the holding metal fittings and half-pitch lever. can be placed.
