By moving and arranging the swing cam 23, the movement control member 26, the latching plate 43, and the engaging plate 45 in three positions in the direction,
is selectively operated to switch to a needle selection state, a thousand stitch 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, when all the actuating pieces 41 of the actuating member 39 corresponding to each knitting needle 4 participating in knitting are moved to the lower position and the carriage 17 is slid in the direction of the arrow in FIG. Each time the course changing member 34 corresponds to the actuating piece 41, the actuating protrusion 36a of the actuating piece 36
engages with the actuating protrusion 41a of the actuating piece 41, and the course changing member 34 is moved to the forward position against the elasticity of the spring 38,
As shown in FIG. 1, the operating portion 35a of the knitting needle operating piece 35
is inserted into the guide cam 31.

Also, as the carriage 11 slides, the needles 4 (4a) participating in the knitting move along the lowering cam 21 and the swing cam 23 arranged on the right side of the figure to the front end of the guide cam body 22 after knitting is completed. Alignment guided and movement imparting member 24
Due to the magnetic absorption force, the magnetic inclined guiding surface 22a of the guiding cam 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 movement imparting member 24 is restrained from moving backward, and 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 7. As shown in FIG.
The butts 4a of the knitting needles 4 that are attracted to the guide cam 31, are moved in the transverse direction along the rear surface of the guide cam 31, and escape from the lower surface of the carriage 1T without being affected by the course changing member 34, and are sorted backwards. Magnetic gradient guiding surface 22 of body 22
After being moved backward along a, the magnetic guide cam surface 22b
The carriage 17 is moved laterally from its retracted position along
Escape from the bottom of.

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. The yarn is introduced into either the butt passages X or y on the lower surface, and as the yarn is fed from the yarn feeder at the two positions before and behind the hook of the knitting needle 4, knitting of two-color simultaneous knitting and knitting as shown in part A of FIG. , and other pattern knitting such as tuck knitting.

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. 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. After matching.

The magnetic guide cam surface 22b of the guide cam body 22
The bat escapes from the lower surface of the carriage 17 through the rear bat guide passage.

Further, as the carriage 17 slides, the path changing member 34 is placed in a lower position.

Regarding the portion corresponding to 41, as shown in FIGS. 4 and 7, the operating protrusion 36a of the operating piece 36 engages with the operating protrusion 41a of the operating piece 41, so that the course changing member 34 is operated by the knitting needle. The operating portion 35a of the piece 35 is moved to the forward position where it is recessed into the guide cam 31.

It will be done.

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 sorting pattern based on this is erased, and as the yarn is fed from the rear yarn feeder, flat knitting is performed as shown by area ■ in part B of FIG. 9, and the actuating piece located at the lower position For the knitting needle group corresponding to No. 41, the above-mentioned sorting pattern 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 ■ in part B of Fig. 9. and other pattern knitting such as tuck knitting.

Furthermore, when the arrangement position of each actuating piece 41 is changed up or down, 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 unchanged are reversed. , as shown by ranges I and l in section C of FIG. 9, partial pattern knitting is performed that is different from the previous case.

Further, in this knitting machine, for example, by using a pattern card 11 with signal holes provided at all perforation positions, the butt 4a of the full-knitting needle 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 path 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 means for acting on the course changing member by sliding the carriage to move the course changing member. In the knitting needle actuating device, the actuating means is provided separately for each knitting needle in the row, and has an operating position in which the actuating means acts on and moves the course changing member; By constructing the structure with a large number of actuating pieces that can be moved and placed separately between non-acting positions that do not act on members, the actuating pieces that correspond to the required number of continuous knitting needle groups out of the large number of knitting needles that participate in knitting can be actuated. When the actuating piece corresponding to the other group of knitting needles is moved to the non-working position at the same time as the other knitting needle group is moved to the non-working position, the course changing member moves only when it corresponds to the working piece in the working position as the carriage slides. Then, for one of the two knitting needle groups, 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 pattern of the needle selected based on the control of the pattern card, etc. The needle selection pattern based on the control is maintained in the same state so that partial pattern knitting can be performed, and
without being based on pattern signals from control means such as pattern cards,
When the butts of a large number of knitting needles participating in knitting are set to be guided to a fixed position as the carriage slides, and the actuating pieces corresponding to each knitting needle are arranged separately in working positions and non-working positions, The selection of knitting needles is performed only by the cooperative action of each actuating piece and the course changing member, and an excellent effect is achieved in that a variety of patterns can be knitted without any limitation in pattern width.

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.
