Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a yarn feeding device for a knitting machine.

[Prior art] Conventionally, as a yarn feeding device for knitting machines, for example,
As shown in Publication No. 58-12087, a hook portion is provided on the front side of a carriage that is slidably installed on a needle bed in which a large number of knitting needles are individually arranged in a row so as to be movable back and forth, and a hook portion faces the hook portion of the knitting needles. and opposed needles capable of knitting a stitch that is the reverse side of the stitch knitted by the knitting needles by moving in the front-rear direction; Some are equipped with a yarn opening for supplying knitting yarn.

However, according to this conventional method, in particular, when moving the thread end in the lateral direction to supply knitting yarn to the hook of the opposing needle, it is necessary to Often, as shown in FIG.
Accidents such as damage to the train or the movement of the formation operating mechanism have occurred.

For this reason, the applicant attempted to raise the position of the thread A a little higher when moving the thread A a little laterally to prevent interference with the latch B1 of the opposing needle B.
The knitting yarn C often comes off the hook of the opposite needle B and does not enter the hook, resulting in a so-called missed stitch.

In addition, as another attempt, as shown in FIG. 2, when moving the yarn head A laterally, by reducing the amount of advance of the opposing needle B, the yarn head A is moved into the opposite needle B.
Although this can be placed at a lower position closer to the hook of needle A and interference between the thread A and latch B1 of opposing needle B can be prevented, the old stitch D will be stretched more than necessary and the already determined stitch size will be distorted. There were flaws.

[Purpose] However, in order to eliminate the drawbacks of the conventional ones, the present invention has a structure in which the lower front part of the thread is sloped obliquely forward and upward from the lower surface to approximately the height of the lower surface of the latch presser plate. A notched inclined surface is formed so as to prevent the yarn opening from colliding with the side surface of the open latch of the opposing needle when the yarn opening is moved laterally during yarn feeding, and also to ensure that the latch is opened. The aim is to maintain this condition so that the yarn feeding operation can be carried out safely and reliably.

[Embodiment] An embodiment embodying the present invention will be described in detail below with reference to FIGS. 3 to 7.

In the figure, reference numeral 1 denotes a needle bed, on the front edge of which a large number of comb teeth 2 are arranged at equal intervals, and between each of the comb teeth, knitting needles 3 are arranged so as to be movable back and forth.

In the figure, reference numeral 4 denotes a carriage that is installed on the needle bed 1 so as to be able to advance toward the knitting needle row pitch, and on its lower surface,
A butt guide passage 5 that introduces and guides the butt of the knitting needle 3 of the needle bed 1, and a needle operating body 6 that allows one knitting needle to move the butt back and forth between the knock-over position and the flat-out position at the left and right center portions. and is provided.

Further, on the front side of the carriage 4, there is provided an opposing needle 7 whose hook portion faces the hook portion of the knitting needle 3 and is capable of knitting a front stitch whose structure is opposite to that of the back stitch knitted by the knitting needle 3. The opposing needle 7 is movable in the front-rear direction and the up-down direction, and can also be rotated within a small angular range (approximately 60 degrees).
A drive mechanism (not shown) for providing each of the above movements
A handle 8 connected to is fixed.

In the figure, reference numeral 9 denotes a substantially cylindrical thread opening provided in the front part of the carriage above the opposed needle 7, the upper part of which is connected through a lateral movement member (not shown) so that it can be integrally moved in the left and right direction. In addition to being movable, it is also connected to a member (not shown) that drives in the vertical direction, thereby making it possible to move left and right by approximately three pitches of the knitting needle array, and also to move the height shown in FIG. It is vertically movable between the position and the lower position shown in FIGS. 4b and 7b. The lower front portion of the thread opening 9 is formed with an inclined surface 10 that slopes diagonally forward and upward from its lower surface to the height of the lower surface of the latch presser plate at the lower position described later.

In the figure, reference numeral 11 denotes a latch presser plate fitted to the thread opening 9, which holds the open latch 7A of the opposing needle 7 when feeding the knitting yarn T to the hook of the opposing needle 7 through the thread opening 9. Press the front side so that it faces diagonally upward to maintain its open state. As described above, the latch press plate 11 is movable between the lower position where it presses the latch 7A and the upper position where it does not act on the latch 7, and is connected to a drive member (not shown) for moving it up and down. While being connected, it is made movable in the left-right direction integrally with the thread opening 9.

Note that the yarn opening 9 and the latch presser plate 11 are provided with an opening groove that allows the knitting yarn T to be replaced without cutting it, but the width of this groove is smaller than the width of the tip of the latch 7A of the opposing needle 7. It is set.

In the figure, reference numeral 12 denotes a substantially groove-shaped needle guide member provided on the lower side of the front part of the carriage, which guides the insertion of the opposing needle 7 and one knitting needle 3 in a state where they are lined up from side to side. A pair of left and right sinkers 13 are formed. Reference numeral 14 denotes a fabric presser brush fixed to the lower surface of the needle guide member 12. The needle guide member 12 and the knitting fabric presser brush 14 are integrally movable in the front-rear direction. 15 is a latch opening brush that maintains the latches of the knitting needles 3 and opposing needles 7 in an open state.

This embodiment is configured as described above.

In this embodiment, both the back stitch knitting using the knitting needles 3 and the front stitch knitting using the opposing needles 7 can be carried out for the first stitch.
Since it is implemented in exactly the same manner as that shown in Publication No. 120847, a detailed explanation thereof will be omitted, but an outline of the method of organizing the table will be particularly explained below.

That is, the butt of one knitting needle 3 is made to correspond to the needle actuating body 6, the carriage 4 is fixedly arranged here, and the knitting needle 3 is first moved from the state shown in FIGS. 4a and 4b to the needle actuating body 6. After the old knitting needle K has been moved forward to the position where the needle K is removed, the counter needle 7 is rotated and raised slightly to move its hook to the knitting needle 3.
In this state, connect both knitting needles 3 and 7 to the hook of
By integrally retreating, the old stitch K
The hook is knocked over from the knitting needle 3 and transferred to the opposing needle 7, and at the same time, the hook is removed from the opposing needle 7, and the hooks of both the knitting needles 3 and 7 are uncoupled. Then, move the opposing needle 7 forward to the position shown in FIG.
In this position, the latch of the opposing needle 7 is kept in an open state by the latch presser plate 11, and in this state, the yarn opening 9 is moved laterally over the opposing needle 7, so that the knitting yarn T is transferred from the yarn opening 9 to the opposing needle 7. feed on the hook.
Then, as shown in FIGS. 6a and 6b, by moving the opposing needles 7 forward, the old stitch K is knocked over and a new front stitch K1 is knitted using the knitting yarn T. After that, in the same way as above, by joining the hooks of both knitting needles 3 and 7 behind the comb teeth 2 and moving both knitting needles 3 and 7 forward as one,
The surface stitch K1 is transferred from the opposing needle 7 to the knitting needle 3, and the hooks of both knitting needles 3 and 7 are uncoupled. Thus, by changing the state shown in Fig. 7a and b, the surface K1
One formation operation is completed.

Particularly in the above knitting process for the front stitch K1, when the knitting yarn T is supplied from the yarn opening 9 to the hook of the facing needle 7, since the lower front side of the yarn opening 9 is notched by the inclined surface 10, the yarn opening When the thread 9 moves laterally, it does not collide with the tip of the open latch 7A of the opposing needle 7, and the thread head 9 can be moved laterally at a lower position as close to the opposing needle 7 as possible. The thread T can be reliably supplied to the hook of the facing needle 7.

[Effects] As described in detail above, the present invention is equipped with an opposing needle, a thread opening, and a latch presser plate in the carriage, and by moving the thread end laterally over the opposing needle, the latch presses the open latch of the opposing needle. The target is a knitting machine that knits stitches by supplying the knitting yarn to the hooks of opposing needles while holding it diagonally forward and upward with a plate. A notched inclined surface is formed so as to be inclined diagonally forward and upward over the height of the lower surface of the latch presser plate.

Therefore, when feeding knitting yarn to the hooks of opposing needles,
In particular, the front lower part of the horizontally moving thread is cut diagonally forward, and the latch presser plate presses the open latch on the front side of the thread so that it faces diagonally forward and upward, so that the opposite needle with the thread opening facing forward can be created. There is no collision with the tip of the latch of the needle, thereby preventing accidents such as damage to the latch or thread opening of the opposing needle or the knitting operation mechanism not being able to operate, and ensuring the yarn feeding operation is always safe and reliable. It is something that can be accomplished. In addition, since collisions are prevented in this way, the lower surface of the thread can be moved laterally at a lower position closer to the opposing needles, and the latch presser plate is also disposed further downward along with the thread to make the opened latch more secure. Since it can be pressed in the opening direction, it exhibits excellent practical effects such as being able to reliably feed the knitting yarn into the hooks of opposing needles.
