is selectively operated to switch to a needle selection state, a flat knitting state, or a carriage 17 removal state.

The operation of the knitting machine configured as described above will now be described.

Now, FIGS. 1 and 2 show a state in which the sliding plate 46 has been moved to the needle selection position.

In this state, all the actuating pieces 41 of the actuating member 39 corresponding to the knitting needles 4 participating in knitting are moved to the lower position, the actuating piece 36 of the course changing member 34 is placed in the lower first position, and the carriage 17 7, the operating protrusion 36a of the operating piece 36 engages with the operating protrusion 41a of the operating piece 41 each time the course changing member 34 comes into contact with the operating piece 41. The course changing member 34 is moved to the front position against the elasticity of the spring 3B, and the operating portion 35a of the knitting needle operating piece 35 is retracted into the guide cam 31 as shown in FIG.

In addition, as the carriage 17 slides, the needles 4 (4a) participating in the knitting are moved to the front end of the guide cam body 22 along the lowering cam 21 and the swing cam 23 arranged on the right side of the figure after knitting is completed. Alignment guided and movement imparting member 24
Due to the magnetic absorption force, the magnetic gradient guiding surface 22a of the guiding lume body 22
It is attempted to be moved sequentially backward along the .

Then, the rear end portion of each knitting needle 4 comes into contact with the movement control piece 29 of the movement control member 26 located at the operating position behind the movement imparting member 24.

At this time, as is clear from FIG. 2 and FIG.
Since the rear end portion of the knitting needle 4 corresponding to the knitting needle 4 can move downward against the elasticity of the elastic member 5, the rear end of the knitting needle 4 becomes inclined due to the backward movement due to the action of the movement imparting member 24. It passes through the lower end of the movement control piece 29 and is moved rearward.

Further, as is clear from FIGS. 1 and 8, since the rear end of the knitting needle 4 corresponding to the lowering prevention protrusion 9a of the pattern plate 9 in the operating position is prevented from lowering, the movement control While in contact with the piece 29, the backward motion by the movement imparting member 24 is restrained and the bill is moved in the lateral direction.

In other words, each knitting needle 4 is moved slightly in the front-rear direction near the magnetic gradient guide surface 22a of the guide cam body 22 by the cooperative action of the movement imparting member 24 and the movement control member 26 based on the selection action of the descent prevention member T. As shown in FIG.
The butts 4a of the knitting needles 4 are attracted to the guide cam 31, are moved in the lateral direction along the rear surface of the guide cam 31, escape from the lower surface of the carriage 17 without being affected by the course changing member 34, and are sorted backwards. Magnetic gradient guiding surface 2 of cam body 22
2a, the magnetic guide cam surface 22
The carriage 1 is moved laterally from its retracted position along
Escape from the bottom of 7.

Therefore, all the knitting needles 4 participating in knitting are sorted into two positions, front and back, on the needle bed 1, and when the carriage 17 is slid in the direction opposite to the arrow in FIG. As shown in part A of FIG. 10, as shown in part A of FIG. 10, two-color simultaneous knitting, Other pattern knitting such as tuck knitting is also performed.

Next, a plurality of actuating pieces 41 corresponding to a required number of continuous knitting needle groups are arranged as one unit at alternate lower positions and upper positions, and for example, seven actuating pieces 41 are actuated as a unit as shown by solid lines in FIG. When the carriage 17 is slid with the piece 41 in the lower position and the seven actuating pieces 41 shown in chain lines in the upper position, the course changing member 3 provided on the carriage 17 is moved.
Regarding the portion corresponding to the actuating piece 41 where 4 is placed in the upper position, the actuating protrusion 36a of the actuating piece 36 does not engage with the actuating protruding part 41a of the actuating piece 41, as shown in FIGS. 5 and 8. Therefore, the course changing member 34 is disposed at a rear position where the operating portion 35a of the knitting needle operating piece 35 is projected into the bat guide path in front along the guide cam 31 by the elasticity of the spring 38.

Therefore, the butt 4a of the knitting needle 4 guided into the front butt guide passage along the guide cam 31 based on the sorting action of the movement control member 26 is engaged with the operating portion 35a of the course changing member 34 in the protruding state. At the same time, the bat is moved rearward, attracted to the magnetic guide cam surface 22b of the guide cam body 22, and escapes from the lower surface of the carriage 11 through the rear butt guide path.

Further, as the carriage 1T slides, the portion of the course changing member 34 corresponding to the operating piece 41 disposed in the lower position is moved as shown in FIGS. 4 and 7.
Since the operating protrusion 36a of No. 6 engages with the operating protrusion 41a of the operating piece 41, the course changing member 34 is moved to the forward position where the operating part 35a of the knitting needle operating piece 35 is recessed into the guide cam 31. .

Therefore, the butts 4a of the knitting needles 4 sorted into two positions, front and back, by the sorting action of the movement control member 26 escape from the lower surface of the carriage 17 in that state without being subjected to the course changing action of the course changing member 34.

As a result, when the carriage 17 is slid in the opposite direction, among the knitting needles 4 participating in knitting, the knitting needle group corresponding to the actuating piece 41 disposed at the upper position as described above is moved to the movement control member 26. The type of sorting based on the pattern is erased, and as the yarn is fed from the rear yarn feeder, flat knitting is performed as shown in area 1 in part B of FIG. For the knitting needle group corresponding to 41, the pattern of the sorting is left as is, and as the yarn is fed from the front and rear yarn feeders, two-color simultaneous knitting is performed as shown by range n in part B of Fig. 10. and other pattern knitting such as tuck knitting.

Furthermore, as shown in FIG. 9, if knitting is performed by switching only the operating piece 36 of the course changing member 34 from the lower first position to the upper second position in the above state, the above case is different. In contrast, when the course changing member 34 corresponds to the actuating piece 41 in the upper position, the acting protrusion 36a of the actuating piece 36 engages with the actuating protrusion 41a of the actuating piece 41, and the course changing member 34 moves as shown in FIG. It will be moved from the rear position shown in Figure 7 to the front position shown in Figure 7.

Therefore, the knitting needle group in which the sorting pattern based on the movement control member 26 is erased and the knitting needle group in which the sorting pattern remains as is are reversed, and the above-mentioned knitting needle group is reversed, as shown by ranges I and l in part C of FIG. Partial pattern knitting is performed differently than in other cases.

In addition, in this knitting machine, for example, a pattern card 11 with signal holes provided at all perforation positions is used, and the butt 4a of the full-knitting needles 4 participating in knitting is moved along the guide cam 31 as the carriage 17 slides. If the actuating pieces 41 corresponding to each knitting needle 4 are selectively arranged in a position where they engage with the course changing member 34 or a position where they do not engage with the course changing member 34, each actuating piece The knitting needles 4 are sorted into two positions, front and back, only by the cooperative action with the course changing member 34, and it is possible to knit a variety of patterns with no limitation on pattern width.

In addition, in the embodiment, the actuating piece 41 is the actuating piece 36.
When the course changing member 34 is disposed at the rear position without engaging with the knitting needle 4, the butt of the knitting needle 4 guided to the front butt guide passage is moved rearward to change its course. However, contrary to this configuration, when the operating piece 41 engages with the operating piece 36 and the course changing member 34 is moved forward, the magnetic gradient guiding surface 22a of the guiding cam body 22
Nearby, the butt of the knitting needle 4 guided to the rear butt guide path along the guide surface 22a may be moved forward to change its course.

As described in detail above, the present invention provides a butt for knitting needles that is movable between three positions and guided to a fixed position in one of the three positions on a carriage that is mounted on a needle bed so as to be slidable from side to side. a course changing member for moving the butt to another position to change the course of the butt; and an actuating member on the needle bed that acts on the course changing member by sliding the carriage to move the course changing member. In the knitting needle actuating device, the actuating member is movably arranged in two different positions with respect to the course changing member, and the acting portion of the course changing member that acts on at least the actuating member is placed in one of the two positions. Since the device is arranged so that it can be switched between a position where it can act on the actuating member at one position and a second position where it can act on the actuating member at the other position, it is possible to Moving and arranging the operating members corresponding to the required number of knitting needle groups to one of two positions, and moving and arranging the operating members corresponding to the other knitting needle groups to the other position,
When the operating portion of the course changing member is switched to the first position, the course changing member is moved only when it corresponds to the operating member in the one position as the carriage slides, and one of the two groups of knitting needles is moved. For the knitting needle group, for example, the needle selection pattern based on the control of the pattern card etc. is erased by the course changing member, and for the other knitting needle group, the needle selection pattern based on the control of the pattern card etc. remains unchanged. In this state, partial pattern knitting can be performed while the needle is selected by the course changing member simply by switching the operating portion of the course changing member from the first position to the second position in the above state. The objects of the knitting needle group whose pattern is erased and the knitting needle group whose selected needle pattern is maintained as it is can be easily reversed, and it is possible to perform partial pattern knitting that is different from the above case. It has excellent effects.

It should be noted that the present invention is not limited to the configuration of the embodiment described above, and the configuration of each part can be arbitrarily changed without departing from the spirit of the invention.
