[Detailed description of the invention] The present invention relates to a needle selection device for a hand knitting machine.

The present invention includes a locking member that can lock a desired knitting needle in two lower positions different from a normal position on a needle bed, and a carriage that slides on the needle bed that acts on the knitting needle to move the needle to the normal position. Said 2
The invention is characterized in that it is equipped with a needle actuating member that allows the knitting needles to take three positions, and a needle selection cam that selects and arranges the knitting needles in three positions in the front and rear directions according to the three positions.
To provide a needle selection device capable of knitting complicated patterns with various variations by a simple operation by being able to selectively arrange the needles in different positions.

A specific example thereof will be explained below based on the drawings.

Reference numeral 1 denotes a needle bed which can move a large number of knitting needles 2 back and forth, up and down, and is always resiliently held at the normal upper position by springs 3. A rear needle support plate 4 fixed to the rear of the needle bed holds the knitting needles 2. The needle guide plate 5 has a needle insertion hole 4a having a width twice or more than the width of the needle insertion hole 4a, and is provided with a groove 5a approximately the same width as the knitting needle 2 at the front and rear approximately middle, and restricts the movement of the knitting needle 2 in the left-right direction. to fix.

Therefore, only the rear part 2a of the knitting needle 2 can move in the left-right direction against its own elastic force, and when it moves, it generates a return force to its original position.

Reference numeral 6 denotes a locking member fixed to the rear needle support plate 4, on which a first projection 6a projects within the vertical movement locus of the knitting needle 2 in its normal position, and a second projection similarly projects below the locking member. A recess 6d is formed between the protrusion 6b, the first protrusion 6a, and the second protrusion 6b under the recess 6C1 and the second protrusion 6b.

Therefore, when the knitting needle 2 is lowered against the elastic force of the spring 3, only the rear part 2a of the knitting needle 2 is attached to the first protrusion 6a of the locking member 6.
The needle bed 1 is engaged with the needle bed 1 in the longitudinal direction (in the lateral direction as shown by the dashed dotted line in Figure 3) and is moved down while resisting its own elastic force, and further engages with the second protrusion 6b. It is also lowered while being moved laterally against its own elastic force, and returns to its normal lower position due to its own elastic force at the recesses 6c and 6d, as shown in Figure 6. Return to

Therefore, even after the descent to the knitting needle 2 is released at each position, the first protrusion 6a and the second protrusion 6

Reference numeral 14 denotes a starting plate which is rotatably supported on the needle bed 1 and rotates from the position shown by the solid line in FIG. 1 to the suspended position shown by the two-dot chain line in FIG. 15,
16 operating rod pressing member 17 and needle selection card retracting device (not shown) are sequentially operated.

Reference numeral 15 denotes a movable member which is moved laterally by a pin 14a fixed to the activation plate 14 and a cam groove 15a formed in the movable member 15, and is moved to a position corresponding to the middle of the other leg 10c of the actuating rod 10 at one point in FIG. A notch 15b for moving the actuating rod 10 shown by a chain line and a notch 15c for moving the actuating rod 10 shown by a broken line in Figure 1 are formed.

Reference numeral 16 designates a fixing member, which has a notch 16a into which the actuating rod 10 shown in solid line in FIG. do.

The moving member 15 and the fixed member 16 constitute a needle selection moving device.

Reference numeral 17 denotes an actuation rod pressing member pivotally connected to the activation plate 14 via a spring (not shown), which depresses the actuation rod 10 in one stroke and separates it from the needle selection card 8, so that the needle selection card 8 can be reversed. .

Reference numeral 18 denotes a needle folding upper member having an inclined surface 18a that is inclined downwardly at the rear end of the knitting needle 2 held in the first lower position and the second lower position. 2
Push up to the position shown by the solid line in Figure 1.

Reference numeral 19 is a carriage equipped with various knitting cams (not shown) for making ordinary stockinette knitting and pattern knitting, and the following needle selection cams.

Reference numeral 20 denotes a guide cam which advances the knitting needles 2 in the knitting position and guides them to the needle selection position, which is rotatable and is always kept in the position shown in FIG. 7 by means of a spring.

Reference numeral 21 denotes a needle folding lower cam which is a needle actuating member that sequentially presses down the butts of all the knitting needles 2 guided to the needle selection position as shown in FIG.

and a first needle selection cam comprising a backward cam section 22b that moves the knitting needles 2 at the upper position back to the knitting emotion position X, and a forward cam section 22c that advances the knitting needles 2 at the first lower position to the first needle selection position Y. It is.

23, as shown in FIG. 9, moves back only the knitting needles 2 at the first lower position y, and allows the knitting needles 2 at the second lower position Z to pass through while maintaining that position. Only the knitting needles 2 at the lower position y are moved back and their rear ends are engaged with the inclined surface 18a of the needle folding upper member 1B and pushed up to the upper position X.
This is a second needle selection cam that includes a return cam part 23b that returns the knitting needles 2 from the second lower position Z to a forward cam part 23c that advances the knitting needles 2 at the second lower position Z to the second needle selection position Z.

24 retreats the knitting needles 2 at the second lower position 2 and moves the needle folding upper member 1
This is a return cam that is engaged with 8 and pushed up to return to the upper position X.

25 is swingably supported by the carriage 19 and always in contact with the operating member 13, and when the sliding direction of the carriage 19 is reversed, it swings itself and operates the operating member 13 from the front position to the rear position. It is a swinging member that moves.

The operation of the above configuration will be explained below.

First, if the carriage 19 is not slid on the needle bed 1 but its sliding direction is reversed, the actuating member 13 is moved from the front position to the rear position by the swinging member 25, and the activation plate 14 is moved from the position shown by the solid line in FIG. Rotate to the dotted chain hanging position.

Therefore, due to the engagement action I between the pin 14a and the cam groove 15a, the moving member 15 moves from the position shown by the fourth solid line to the hanging position shown by the two-dot chain line, and the operating rod 10 becomes in a state in which it can be lowered.

Next (the actuating rod pressing member 17 is pushed down one step and separated from the needle selection card 8, and after that, the card 8 is reversed and the next new signal is generated, and then the actuating member 13 returns to its original position, and the activation plate 14 returns to its original position.

Therefore, first, the actuating rod 10 is raised by the spring 12, and the tip of the actuating rod 10 that engages with the large hole 8a of the needle selection card 8 passes through the large hole 8a, and is positioned upwardly as shown by the solid line in FIG. Therefore, the actuating rod 10 that engages with the small hole 8a passes through only the narrow end 10b at its tip, and is in an intermediate position as shown by the dashed line in FIG. is brought into contact with the needle selection card 8 (the needle selection card 8) and is in the downward position as shown by the dotted chain line in Figure 1.

Thereafter, the moving member 15 returns to the position shown by the solid line in FIG. 7 to the position shown by the chain dotted line in Figure 5 (shown in Figure 6).

Further, the actuating rod 10 at the intermediate position is moved later than the actuating rod 10 at the lower position by the notch 15b, and the fixing member 16
The operating rod 10 is moved to the hanging position shown by the dashed line in FIG.

At this time, the operating rod 10 in the upper position is inserted into the notch 1 of the fixing member 16.
The needle selection plate 7, which the operating rod 10 engages with, remains in the position shown by the solid line in FIG. 5 (shown in FIG. 6A).

After that, if the carriage 19 is further slid, the induction cam 20
The butts of all the knitting needles 2 guided to the needle selection position are sequentially pushed down by the needle folding lower cam 21 as shown in FIG.

At this time, as shown in FIG. 6A, the first needle selection protrusion 7a of the needle selection plate 7
The rear part 2a of the knitting needle 2, which was prevented from descending, moves from the position shown by the solid line in FIG. After the downward force of the lower cam 21 is released, the cam 21 returns to the position indicated by the solid line by the elastic force of the spring 3 and is held at the upper position X.

Also, as shown in FIG. 6B, the second needle selection protrusion 7bl of the needle selection plate 7
The rear part 2a of the knitting needle 2, whose descent is thus prevented, engages with the first protrusion 6a and moves laterally against its own elastic force from the position shown by the solid line in FIG. 6A to the position shown by the two-dot chain line. Even after the lowering force of the needle folding lower cam 21 is released, the needle folding lower cam 21 is engaged with the first protrusion 6a by its own elastic force and is prevented from rising, so that the needle folding lower cam 21 is not lowered from that position and is prevented from rising.
is maintained.

Furthermore, as shown in FIG. 6C, the knitting needles 2, which are not prevented from descending by the needle selection projections of the needle selection plate 7, descend to the position shown by the dotted chain line in FIG. and held at the second lower position Z.

As described above, the knitting needles 2 are selectively held in three positions in the vertical direction: the upper position X, the first lower position y, and the second lower position Z,
Subsequent sliding of the carriage 19 causes the upper position
The knitting needles at positions A to C shown in solid lines in FIGS. ) The knitting needles pass below the first sorting cam part 22a of the first needle selecting cam 22, are retreated by the second needle selecting cam 23, and are moved back to the needle folding upper member 18.
After being pushed down to the upper position by the inclined surface 18a of the first needle selection cam 22, the forward cam portion 22c of the first needle selection cam 22 moves forward to the first needle selection position Y, aligns the needle, and moves the needle to the second lower position 2 (FIG. 1,
The knitting needles shown in FIG.
After passing under the first sorting cam part 22a and the second sorting cam 23a of the second needle selecting cam 23, being retreated by the return cam 24, and being pushed up to the upper position by the inclined surface 18a of the needle folding upper member 18, Forward cam portion 2 of second needle selection cam 23
3c, the needles are advanced to the second needle selection position Z and aligned.

Therefore, the knitting needle 2 corresponding to the large hole 8a of the needle selection card 8 is in the knitting emotional position X, the knitting needle 2 corresponding to the small hole 8b is in the first needle selection position Y, and the knitting needle 2 corresponding to the non-perforated part 8cG is in the knitting emotional position X. The needles are selectively arranged in three positions, front and rear, such as the second needle selection position Z.

As described above, the device of the present invention is provided with a locking member capable of locking a desired knitting needle at two lower positions different from the normal position on the needle bed, and a locking member that acts on the knitting needle on the carriage that slides on the needle bed. By providing a needle actuating member that causes the knitting needles to take three positions (the normal position and the two positions), and a needle selection cam that selects and arranges the knitting needles in three positions in the front and back direction according to the three positions, the carriage can be simply moved. By simply sliding the knitting needles, the knitting needles can be sorted and placed in three positions, front and back, and then by introducing the knitting needles into separate butt passages, it is possible to knit patterns with complex variations, which is extremely effective. play.
