Therefore, when the sliding plate 101 is selectively placed in one position or the other and pattern knitting such as two-color simultaneous knitting or one-point pattern knitting is performed, the guiding effect is exerted as shown in FIGS. 12 and 26. The butt 2a of the knitting needle 2 guided from inside the open end of the guide cam 80 placed in the position toward the same end collides with the open end or is introduced into the reference butt passage 68. Without any problem, it is guided forward onto the guiding cam 80 along the one-way guiding cam 83 at the protruding position, and then smoothly guided to the lower part of the lowering cam 75. Furthermore, when flat knitting is performed with the sliding plate 101 selectively placed in the position, the one-way guide cam 83 is switched to the avoidance position as shown in FIG. After the yarn is fed and latched to the knitting needle 2, and the knitting needle 2 is retracted slightly behind the knockover position by the main knitting cam 66, the knitting needle 2 guided into the reference butt passage 68 is moved forward again by the one-way guide cam 83. The hook protrudes slightly in front of the comb teeth 3, and the set-up can be easily and reliably performed without the inconvenience of the hooked yarn coming off the hook. After the knitting main cam 66 retreats a little behind the knockover position to form a new stitch, the knitting needle 2 guided into the reference butt passage 68 is advanced again by the one-way guide cam 83 and the hook is moved to the comb. There is no problem that the newly formed stitches of a predetermined size that protrude slightly in front of the teeth 3 become loose and the amount of yarn is absorbed by other stitches of the same course, resulting in uneven stitch sizes. A knitted fabric with uniform stitch size can be obtained.

Next, during pattern knitting such as two-color simultaneous knitting, the end knitting needles 2 at both ends of the working knitting needle group, which are subjected to the rolling down action of the rolling down cam 75 on the lower surface of the base plate 60, are moved to the rest needle butt passage adjacent to the end knitting needles. 28 to 33 show the structure of an end needle selection device for moving forward near the outer end of the lowering cam 75 based on the detection of the resting knitting needle 2 at 65 to change the course of the end knitting needle.

The end needle selection member 143 may not be immediately returned to the rear position due to the action of the tension spring 141, etc., and the end before returning where the butt 2a of the second knitting needle 2 adjacent to the first end knitting needle is in the operating position. It engages with the butt acting part 143a of the needle selection member 143, and due to its reaction, the butt 2 of the second knitting needle 2
A may be given a forward movement force. However, in this embodiment, the lowering cam 75
Since the barrier piece 144 is provided on the front edge of the
The forward movement of the butt 2a of the second knitting needle 2 is prevented by the barrier piece 144, and the risk of the butt being mistakenly sorted to the forward position is reliably prevented, and the end needle selection member 143 is The engagement between the butt acting portion 143a and the butt 2a of the second knitting needle 2 and the action of the tension spring 141 reliably return the knitting needle from the front working position to the rear non-working position.

Furthermore, when knitting a tuck or a slip pattern using the hand knitting machine, it is carried out in accordance with the above-mentioned sequence of operations, but below, in particular, the operations related to the present invention will be explained by operating the upper surface of the carriage. When the slide plate 101 is placed in position using the knob 104 and the push button 91b for tuck stitch or slip stitch stitch is pressed, the guide cam 80, the one-way guide cam 83, and the sensing member 142 are activated for the two-color simultaneous stitch stitch. The opening/closing cam 69 and the tuck cam 70 are arranged at positions suitable for the pattern knitting described above. Therefore, if the carriage is slid back and forth in this state, the knitting operation of the desired pattern will be performed in the first half of the sliding direction of the carriage, and the knitting operation of the desired pattern will be performed in the second half, as in the case of the two-color simultaneous knitting. A needle selection operation is performed at .

Next, when one-point pattern knitting (partial pattern knitting) of two-color simultaneous knitting is to be performed using this hand knitting machine, for example, the sequence of operations described above is followed. However, as shown in FIGS. 25 and 26, the needle bed 1
While installing the operating cam 127 at the desired position on the
As shown in FIG. 18, when the sliding plate 101 is moved to a position using the operation knob 104 on the top surface of the carriage and the central push button 91b for two-color simultaneous knitting is pressed, the carriage is moved in the same way as in the previous case. Two different knitted butt passages 73 and 74 are formed on the lower surface in two positions, front and rear. On the other hand, as the sliding plate 101 moves, the guide cam 80 on the lower surface of the carriage is moved from the guiding position shown in FIGS. It is switched to the guidance non-effect position shown in Fig. 23. Also, the switching operation plate 125 is operated by the cam groove 108 of the sliding plate 101.
is rotated clockwise from the state shown in FIG. 22, the first actuating member 120 is moved to the right, and as shown in FIG. Engagement part 1 of through hole 124
24a, both actuating members 120, 122 are joined to each other.

In this state, when the carriage is slid to the left in FIG. 13, the butts 2a of the knitting needles 2 involved in the knitting operation are moved to the inclined cam surface 82a of the right fixed cam plate 82 and the front end of the one-way guide cam 83. and are guided to be aligned in sequence at the branching part between the reference butt passage 68 and the butt passage below the lowering cam 75. At this time, the operating cam 1 on the needle bed 1
As for the knitting needles 2 that do not correspond to the cam grooves 132 of No. 27, since the guide cam 80 is arranged in the non-guiding position as shown in FIG.
The butt 2a is introduced into the rear reference butt passage 68 along the guide cam 80, is guided laterally without being affected by the lowering cam 75 and the sorting cam 76, and escapes from the lower surface of the carriage.

Further, for the required number of continuous knitting needle groups corresponding to the cam groove 132 of the working cam 127, when the butt 2a is guided to the branching part, the 27th
As shown in FIG. As the guide cams 80 are rotated, the guide cams 80 are switched from the non-guiding position to the guiding position as shown in FIGS. 26 and 27b, so that the butts 2a of the knitting needles 2 are Lowering cam 75
It is introduced into the lower butt passage and its lowering cam 75
Due to the cooperative action of the needles and the sorting cam 76, the needles are sorted into two positions, front and back, as the handle plate 5 moves based on the knitting needle arrangement signal 16b of a predetermined stage on the needle selection card 16, and the needles escape from the lower surface of the carriage.

Therefore, when the carriage is slid in the opposite direction, the butt 2a of each knitting needle 2 is introduced into either of the knitting butt passages 73 and 74 on the underside of the carriage, and does not correspond to the cam groove 132 of the operating cam 127. For the knitting needle group, flat knitting is performed as yarn is fed from the yarn feeder 62b at the rear position, and for the knitting needle group corresponding to the cam groove 132 of the operating cam 127, the yarn is fed from the yarn feeder 62a, 62b at the front and rear positions. As the yarn is fed, two-color simultaneous knitting is performed.

Next, when knitting flat knitting using this hand knitting machine, when the sliding plate 101 is moved to a position using the operation knob 104 on the top surface of the carriage as shown in FIG. 19, the position shown in FIG. The end cam 107 of the sliding plate 101 causes the second actuating member 12 to
2, the guiding cam 80 is placed in the non-guiding position, the cam groove 108 puts the first and second actuating members 120, 122 in the disengaged state via the switching actuating plate 125, and the cam groove 109 puts the actuating lever 136 in the disengaged state. The one-way guide cam 83 and the sensing member 142 are switched to the avoidance position and the front inactive position, and to the front position where the engagement plate 100 is separated from the endless belt 36 by the cam hole 110.

On the other hand, as the sliding plate 101 moves, the third
As shown in FIG. 7a and FIG.
a, and the rotating lever 150 engages with the coil spring 15.
It is rotated counterclockwise against the action of 2. As the rotation lever 150 rotates, the holding member 93 is pressed against the compression spring 94 by the other leg 150b.
When the operating rod 91 is moved to the left from the state shown in FIG. 34 against the The retaining recess 91a is connected to the holding member 93.
is released from the latching protrusion 93a of the operating rod 9.
1 and the push button 91b are returned to the front position by the action of the compression spring 92. Therefore, the operation knob 104
There is no need to return the push button 91b to the pressed position in a separate operation, and the various switching cams 69 to 72 on the underside of the carriage can switch from a position suitable for pattern knitting to a position suitable for flat knitting, as shown in Fig. 14. automatically switched and placed.

Further, as described above, immediately after the rotating lever 150 is rotated by the amount necessary to release and move the holding member 93 by a predetermined amount, the monopod 150a is moved to the operating protrusion 15.
5, and as shown in FIGS. 35 and 38b, the one leg 150a of the rotary lever 150 is displaced upwardly against the action of the coil spring 152 by its inclined surface 155a, and the driving protrusion 154. Therefore, after the engagement between these two 150a and 154 is released, the rotation lever 150 moves to the monopod 15 as shown in FIGS. 37b and 38b.
0a riding on the upper end of the drive protrusion 154, it is rotated back to the original position by the action of the coil spring 152, and only the sliding plate 101 is further moved toward the position, thereby guiding the lower surface of the carriage as described above. The cam 80 and the like are switched to positions suitable for flat knitting.

If you slide the carriage left and right in this state,
The butts 2a of the knitting needles 2 involved in knitting are guided along the butt path shown by chain lines in FIG.
A flat knitting is performed. In addition, in this plain knitting state, since the one-way guide cam 83 is moved to the avoidance position above the fixed cam plate 82 as described above, the yarn is supplied and latched to the tip hook during the set-up. After being retracted slightly behind the knockover position by the main knitting cam 66, the knitting needles 2 guided into the reference butt passage 68 are advanced again by the one-way guide cam 83 so that the hooks are moved forward of the comb teeth 3. There is no inconvenience of the hooked yarn coming off the hook, and the set-up can be easily and reliably carried out.Furthermore, during the knitting operation of flat knitting, the main knitting cam 66 allows the set-up to be set up at the knock-over position. After the knitting needle 2 is retreated a little backward to form a new stitch, the knitting needle 2 guided into the reference butt passage 68 is advanced again by the one-way guide cam 83 so that its hook slightly protrudes in front of the comb teeth 3. The above-mentioned newly formed stitch of a predetermined size loosens and the amount of yarn is absorbed by other stitches of the same course, and there is no problem that the stitch size becomes uneven, and the stitch size is uniform. You can get land.

Furthermore, in this flat knitting state, the sensing member 142 in the end needle selection device is connected to the rear cam body 64.
Since the butt 2a of the knitting needle 2 at the rest position guided into the needle rest butt passage 65 does not engage with the sensing member 142, wear and tear of both 2a and 142 is prevented. This can be prevented and the carriage can slide smoothly.

In addition, in the pattern knitting state and this plain knitting state, as shown in FIGS. 12, 14, and 22, the operating pin 120c on the first operating member 120
is the contact/separation through hole 1 formed in the second actuating member 122.
24, and the connection between the first and second actuating members 120, 122 is released, so when knitting pattern knitting or flat knitting,
Even if the carriage is accidentally slid with the operating cam 127 still placed on the needle bed 1, the first operating member 120 is only rotated by the operating cam 127, and the guide cam 80, the operating force may not be transmitted to the operating cam 127, and the operating cam 127 may perform incorrect knitting, or the guiding cam 80, the first and second
There is no possibility that excessive force will be applied to various members such as the actuating members 120, 122 and the actuating cam 127, thereby damaging these members or interfering with the knitting operation.

Next, when removing the carriage from above the needle bed 1, as shown in FIG. The engagement plate 100 is moved to a forward position separated from the endless belt 36, and the sliding plate 10
1. The vertical grooves 112a of the actuating pieces 112 on both sides are connected to the latching plate 9.
7 engages with the inclined surfaces 98a of the operating pieces 98 on both sides, and the retaining plate 97 is moved to a forward position separated from the rail portion 99 of the needle bed 1. Therefore, in this state, the carriage can be easily removed upward from the needle bed 1.

Note that the present invention is not limited to the configurations of the embodiments described above, and may include, for example, the arrangement of multiple types of switching cams, a needle selection cam mechanism, a guiding cam, a manual operation member, a holding member, an auxiliary operation member, a release member, etc. The configuration can be modified and implemented as desired without departing from the spirit of the invention.

As described in detail above, this invention has a pair of left and right main knitting cams, multiple types of switching cams such as opening/closing cams and tuck cams that can open and close the return passage, and knitting needles for pattern knitting such as tuck stitching. A needle selection cam mechanism that sorts the butts into two different groups,
The needle selection cam mechanism is equipped with a guide cam that can be switched between two positions to guide or not guide the butt of the knitting needle, and a guide cam on the top surface that can be moved from the normal original position to another moving position by manual operation. By this, a plurality of manual operation members for moving and arranging the various switching cams to positions suitable for the pattern knitting, and a holding position and a manual operation member for holding each of the manual operation members at the displaced movement positions are released. A holding member that is movable between release positions and a holding member that is manually moved from one specific movement position to another movement position within a predetermined reciprocating movement range to cause the guiding cam to be guided from a non-guidance position. In a carriage equipped with an auxiliary operation member that is moved and placed in a position, a release member is arranged between the auxiliary operation member and the holding member so that one side and the other side of the release member correspond to those members, respectively. However, when the auxiliary operation member is moved from the other moving position to the one moving position, the holding member is moved from the holding position to the release position via the release member, so that, for example, When the auxiliary operating member is manually operated to switch from the pattern knitting state such as the tuck knitting to the flat knitting state, the manual operating member is operated at the same time as the guiding cam is switched from the guiding activating position to the guiding non-activating position. The trouble of automatically releasing the holding state, moving the switching cam from a moving position suitable for pattern knitting to a position suitable for flat knitting, and releasing the manual operating member separately from the auxiliary operating member. It is possible to immediately start knitting with a simple switching operation without requiring any manual operation, and it also has the excellent effect of reliably preventing the risk of forgetting to release the manual operation member and performing erroneous knitting. play.
