The present embodiment is constructed as described above, and its operation will be explained below.

First, when the carriage 18 is slid onto the needle bed 1 and the sliding direction is reversed, the drive member 12 is moved to the rear position by the swinging member 24, and the starting plate 13 moves from the position shown by the solid line in FIG. Rotate to the indicated position.

Therefore, due to the engagement between the pin 13a and the cam groove 14a, the movable member 14 moves from the position shown by the solid line in FIG.

Next, the operating rod pressing member 16 engages with the operating rod 9, and the operating rods 9 are pushed down all at once and separated from the needle selection card 7. After that, the needle selection card retraction device is activated to select the needle. After the card 7 is retracted to generate a new signal, the drive member 12 returns to its original position and the activation plate 13 returns to its original position.

Therefore, first, the actuating rod 9 can be raised by the spring 11, and the tip of the actuating rod 9 corresponding to the large hole 7a of the needle selection card 7 passes through the large hole 7a, as shown by the solid line in FIG. Therefore, the actuating rod 9 corresponding to the small hole 7b has only the narrow end 9b of its tip penetrating, and is at the dot-dash dose position in FIG.
The tip of the actuating rod 9 corresponding to the non-porous portion 7c is the needle selection card 7.
It comes into contact with the dotted line dose position shown in FIG. 1.

Thereafter, the moving member 14 returns to the position shown by the solid line in FIG.
is rotated to the position shown by the one-dot chain line and the position shown by the two-dot chain line in FIG.

At this time, the actuating rod 9 in the position shown by the solid line in FIG. 1 engages with the notch 15a of the fixing member 15 and does not move.

Therefore, the first locking member 5 and the second locking member 1) corresponding to the operating rod 9 in the solid line hanging position 1). As shown in FIG. 5, the member 6 is held in an inoperative position where its locking portions 5a and 6a are not located below the knitting needles 2.

Therefore, when the knitting needle 2 is lowered to the position shown by the two-dot chain line and returned to the upper position by the spring 3, it returns unhindered.

Further, the first locking member 5 corresponding to the actuating rod 9 in the position shown by the one-dot chain line is moved to the working position where the locking portion I) 5a is located below the knitting needle 2 via the locking portion 5T, and the second locking member 5 The stop member 6 remains in its inactive position (see figure 5).

In this position, when the knitting needle 2 descends to the position shown by the two-dot chain line, the locking part 5a moves against the elastic force of the actuating rod 9 to the non-acting position shown by the two-dot chain line, and then lowers. When the spring 3 returns to the upper position, the elastic force of the actuating rod 9 prevents the locking portion 5a from returning to the solid hanging position and holds it at the first lower position shown by the dashed dot line.

Also, the first gear +) corresponding to the operating rod 9 at the position indicated by the two-dot chain line
The part 5 remains in the inactive position and the second locking member 6 is moved into the active position (see figure 5).

In this position, when the knitting needle 2 is lowered, it is held at the second lower position (indicated by a two-dot chain line).

After that, if the carriage 18 is further slid, the induction cam 19
The butts of all the knitting needles 2 advanced by are sequentially pushed down by the needle folding down cam 20 as shown in FIG.

Thereafter, the pressing force is released, and the sum is sorted and held in three positions in the vertical direction: the upper position, the first lower position, and the second lower position, according to the needle selection signal of the needle selection card 7, as described above. By the subsequent sliding of the carriage 18, the knitting needles 2L are moved to the upper position.
are retracted by the first selection cam part 21a and the retreating cam part 21b of the first needle selection cam 21 and aligned at the knitting time position (X position), and the knitting needles 2M at the first lower position are aligned at the knitting time position (X position) as shown in FIG. The second needle selecting cam 22 passes under the first sorting cam part 21a, as shown in FIG. The first needle selection cam 21 is forcibly pushed up and returns to the upper position while pressing the locking portion 5a of the first locking member 5 to the inactive position against the elastic force of the operating rod 9, and the first needle selection cam 21 moves forward. The knitting needles 2N aligned at the first needle selection position (Y position) by the cam part 21c and located at the second lower position are aligned with the first selection cam part 21a1.
After passing under the second sorting cam part 22a, it is retracted by the return cam 23 as shown in FIG. The forward cam portion 22c aligns the needle to the second needle selection position (X position).

Therefore, the knitting needle 2L corresponding to the large hole 7a of the needle selection card 7
is the knitting time position (X position), the knitting needle 2M corresponding to the small hole part 7b is at the first needle selection position (Y position), and the knitting needle 2N corresponding to the non-perforated part γC is at the second needle selection position (X position). Sorted and placed.

Thereafter, by introducing the knitting needles 2 at three positions into separate knitting needle butt passages and knitting, patterned knitting (for example, three-color knitting) can be knitted.

Next, a second embodiment of the present invention will be described with reference to FIGS. 9 to 11.

Note that the description of parts common to the first embodiment will be omitted, and their names and symbols will be used.

In particular, this embodiment differs from the first embodiment in the device for moving the first locking member and the second locking member to the operating position.

Reference numeral 51 denotes a driving member that drives the carriage 18 above the rear part of the needle bed 1.
It is composed of a belt that is endlessly stretched over the moving range of the carriage 18, and moves in conjunction with the carriage 18 when the needle bed 1 slides, and when the sliding direction of the carriage 18 is reversed, that is, the drive member 51 An actuating rod pressing member 52 that operates only when the moving direction of
A gear device such as a bevel gear (
(not shown), so that the movement of the drive member 51 and the rotation of the rotary actuating body 53 are not linked, but the movement of the carriage 18 and the rotation of the rotary actuating body 53 are linked.

The rotary operating body 53 has a large hole 7a of the needle selection card 7.
Correspondingly, the actuating rod 9 is in the position shown by the solid line in FIG. 9, and the small hole 7b of the needle selection card 7 is brought into contact with the intermediate protrusion 9d of the actuating rod 9, which is in the position shown by the dashed line in FIG. , a surface cam 53a for rotating the actuating rod 9 is formed, and the surface cam 53a is directed to each actuating rod 9 in one part of the circle.
The actuating rods 9 are shaped so as to rotate, and adjacent actuating rods 9 are formed so as to be shifted from each other so as to operate in a circular manner.

Reference numeral 54 designates a fixing member that forms a notch 54c into which only the actuating rod 9 located at the position shown by the two-dot chain line in FIG. prevent movement.

Next, the relationship between the surface cam 53a of the rotary operating body 53 and the needle selection cam of the carriage 18 will be explained.

The position at which the surface cam 53a begins to rotate the operating rod 9 and move the first locking member 5 or the second locking member 6 to the operating position is at the position of the butt pressing surface 20a of the needle folding down cam 20. The final end of the surface cam 53a acting on the operating rod 9 is formed so as to be inward from the terminal end 20b and outward from the second sorting cam portion 22a.

This embodiment is constructed as described above, and J. Ishita will explain its operation.

First, by sliding the carriage 18 onto the needle bed 1 and reversing the sliding direction, the operating rod pressing member 52 is moved through the driving member 51.
, the needle selection card retracting device operates, retracts the needle selection card 7 and generates a new signal, and moves the operating rod 9 corresponding to the large hole 7a of the needle selection card 7 to the position shown by the solid line in FIG. , small hole 7
The actuating rod 9 corresponding to b is in the position shown by the one-dot chain line in FIG. 9, and the actuating rod 9 corresponding to the non-porous portion γC is in the position shown by the two-dot chain line in FIG.

After that, if the carriage 18 is further slid, the induction cam 19
? The butts of all the knitting needles 2 that have been moved forward are sequentially pushed down to the second lower position by the needle folding down cam 20 as shown in FIG.

While the pushing down action continues, the operating rod 9 is actuated by the surface cam 53a of the rotary actuating body 53, and the first locking member 5
Alternatively, the second locking member 6 is moved to the active position where the locking portion 5a or the locking portion 6a is located above the knitting needle 2 that has been pushed down to the second lower position.

The relationship between the actuating rod 9 and the locking member is such that when the actuating rod 9 in the position shown by the solid line in FIG. When the rod 9 is actuated, the first locking member 5 moves to the operating position, and the actuating rod 9 at the position shown by the two-dot chain line in FIG. Both locking members 6 remain in their inactive position.

If the carriage 18 slides further, the knitting needles 2 will move to the needle folding cam 2.
However, the knitting needles 2 which are prevented from rising by the first locking member 5 remain in the first lower position, and the knitting needles 2 which are prevented from rising by the second locking member 6 are prevented from rising by the second locking member 6. 2 Stays in the downward position.

Therefore, the knitting needles 2 are selectively held in three positions in the vertical direction,
Thereafter, they are sorted and arranged in three positions, front and rear, in the same manner as in the first embodiment.

When the engagement between the rear cam 53a and the operating rod 9 is sequentially disengaged, the first locking member 5 and the second locking member 6 return to their inactive positions, and all the knitting needles 2 return to their upper positions.

The actuating rod 9 is then actuated again by the surface cam 53a for the next corresponding knitting needle 2.

This action is repeated in sequence, and all the knitting needles 2 are selectively arranged in three positions.

As is clear from the above explanation, the device of the present invention has a locking portion that can lock the knitting needles on the needle bed at a position lower than the normal resiliently held position, against the resilient force of the knitting needles. A plurality of first locking members formed at predetermined intervals, and a locking portion capable of locking the knitting needle further below the first locking member corresponds to the locking portion of the first locking member. a plurality of second locking members formed by the above, and an active position in which one of the first and second locking members is selected to lock the knitting needle in the downward direction, or a non-active position in which the knitting needle is not locked in both positions. Since the knitting needle is equipped with an actuating member for the locking member that operates when the first locking member and the second locking member do not act, the knitting needle can be held in the normal spring-held position where the first locking member and the second locking member do not act, or in the position where the first locking member acts. The carriage can be reliably locked in three positions in the vertical direction, including the lower position, or a position further below the locking position by the first locking member where the second locking member acts, and the subsequent sliding of the carriage. When knitting a complicated pattern, for example, three-color knitting, by introducing each knitting needle into each knitting path by motion, it has an excellent effect of being able to knit easily and reliably.
