When the butt 2a is introduced between the both side walls 13 of the butt operating body 12, the butt 2a faces the needle sensing piece 133 of the needle sensing member 127. In this state, each cam wheel 30 to 32
When the lower cam portion 124a of the drive cam 124 faces the cam follower piece 123 of the arrangement changing member 120 as the needle is rotated, the needle sensing piece 133 moves downward based on the spring force of the leaf spring 130 to the rose 1-2a. The spring force of the leaf spring 130 no longer acts on the repositioning member 120. Therefore, due to the spring force of the wire spring 121, the arrangement changing member 120 is held in a position away from the upper surface of the carriage 6, and a wide gap is formed between them.

In addition, the switching plate 96 is based on the spring force of the spring 108.
forward movement is allowed, and the switching plate 96 is
It is introduced into the back stitch cam part (not shown) of the groove-shaped cam on the lower surface. As the switching plate 96 moves forward, the moving plate 101 is moved forward via the connecting plate 105 shown in FIG.
As is clear from Figure 5.

The connecting pin 44.53 of each intermediate member 43.52 is connected to the high cam portion 104a and the low cam portion 1 of each cam groove 104, 103.
03a, so that each intermediate member 43.5
2, the cam follower 42 of the main needle actuating lever 40 is disposed at an upper position where it can engage with the back stitch drive cam 36, and the cam follower (not shown) of the single needle actuating lever 51 It separates from the cam (not shown) for moving the main needle back and forth.

Therefore, as each of the cam wheels 30 to 32 continues to rotate, the switching plate 96 is positioned and held at the front position (first position) according to the cam shape of the back stitch cam part of the grooved cam on the lower surface of the first cam ring 30. be done. Also, one main needle 2 is moved back and forth according to the cam shape of the ft1l cam 36 for back stitch knitting, and back stitch knitting is performed. That is, as shown in FIG. 6, when the cam follower 42 of the main needle operating lever 40 is introduced into the back knitting driving cam 36 via the shallow groove section 37 and the communicating section 38, the bent section 3
By the action of 6a, the main needle 2 or the latch puller is advanced to the position and then moved back slightly. 5
6 is moved from the right side to the left side of the main needle 2 and is also moved up and down to supply reeling yarn -Y to the main needle 2. Thereafter, when the cam follower 42 is introduced into the front line drive cam 35, the main needle 2 is moved back to the knockover position by the action of the bending part 35C, and a new stitch, that is, a back stitch is formed. .

In this way, when the needle sensing member 127 senses the looseness l-28 of the main needle 2 in the rear hat guide passage 18, the needle follower 42 of the main needle actuating lever 40 moves to the back stitch drive cam 36. The cam follower of the single-needle actuating lever 51 is switched to a position where it can receive the action of the single-needle longitudinal movement cam (neither of which is shown in the figure), Back stitches can be knitted by operating only one main needle 2 on the needle bed 1 based on the cam shape of the drive cam 36.

On the other hand, as the carriage 6 moves, the hatch 2a of the main needle 2 located in the rear hatch guide passage 18 or the butt actuating body 1
2. Without being introduced, the front hat guide passage 17
When the butt 2a of the main needle 2 located inside the guide passage 16 is introduced below the movable clamping piece 15 of the butt operating body 12, the needle sensing piece 133 is not opposed to the rose l-2a. When the low cam portion 124a of the cam 124 is opposed to the cam follower piece 123 of the placement change member 120, the placement change member 120 rotates clockwise along with the needle sensing member 127 due to the spring force of the leaf spring 130. The needle sensing piece 133 protrudes into the rear butt guide passage 18. Therefore, the arrangement change member 1
20 and the upper surface of the carriage 6 is narrowed, and the forward movement of the upright piece 96a of the switching plate 96 is caused by the displacement change member 1.
20, and the switching plate 96 is placed and held at the rear position (second position) shown in FIGS.

In this state, as shown in Figure @5, the connection pins 44.53 of each intermediate member 43.52
Since the cam follower 42 of the main needle actuating lever 40 is engaged with the low cam portion 104b and the high cam portion 1031J of the main needle actuating lever 40 through the respective intermediate members 43 and 52,
The cam follower of the single-needle actuating lever 51 is located at a lower position where it can engage with the front opening line drive cam 35 on the upper surface of the second cam ring 31. (not shown).

As each cam wheel 30 to 32 continues to rotate, the switching plate 9
The connecting pin 97 on the top 6 is introduced into the front side knitting cam part (not shown) of the drive cam on the lower surface of the first cam transfer 30, and is moved from the front side switching plate 96 to the rear position (second position) during the knitting operation. Placement is maintained. Also, the butt actuating body 12 is moved back and forth based on the cam shape of the front line drive cam 35, and the single bell 48 is moved back and forth based on the cam shape of the single needle back and forth movement cam (not shown). be done. As the butt operating body 12 moves forward, after the inclined surface 15b of the movable clamping piece 15 shown in FIGS. 2 and 4 engages with the butt 2a of the main needle 2, the movable clamping piece 15 moves to the 4, the rose 1-2a is introduced between the tip of the movable clamping piece 15 and the fixed clamping piece 14. Then, the movable clamping piece 15 is rotated back by its own weight. In this way, after the roses 1 to 2a are introduced into the actuating body 12, both the roses 2a and 12 are moved forward and backward as one, and the main needle 2
The front entrance can be organized by the cooperation of the one bell 48 and one bell 48.

That is, as shown in FIGS. 11 (1) to (3), the main needle 2 is
is moved to the front position, and the old stitch L1 on the main needle 2 is operated. Also, Figure 11 (3)
, As shown in (4), the single bell 48 is rotated in the direction of connection with the main needle 2, and its hook 48a is connected to the hook 21 of the main needle 2. In that state, Figure 11 (
As shown in 4) to (6), the single bell 48 is moved together with the main needle 2 to the flat extraction position on the needle bed 1 side by the action of the bent portion 35b of the surface knitting drive cam 35, etc. , main needle 2
The upper old stitch L1 is transferred to the first wooden nail 4B. Next, the first
As shown in FIG. 1 (7), after the wooden nail 48 is rotated in the direction of releasing the connection and the connection between the hook 48a and the hook 2b of the main needle 2 is released, as shown in FIG. 11 (8), As shown in (9), the first wooden nail 48 is moved to the vicinity of the knockover position.

Then, as shown in Figure 11 (9) and (10),
The yarn opening 56 is moved horizontally and vertically, and the knitting yarn Y is supplied to the hook 4B& of the first nail 4B. Subsequently, the single wooden nail 4B is moved to the knockover position, the knockover operation of the old stitch L1 on the single bell 4B is performed, and a new stitch L2 is formed on the single bell 48.

After that, as shown in Fig. 11 (12) and (13), the new stitch L2 is removed on the 1st bell 4B, and then the 1st thread is removed as shown in Fig. 11 (14). Nail 4B
hook 48& is again coupled to the hook 2b of the main needle 2. In this state, as shown in Fig. 11 (15), the main needle 2
and 1 wooden nail 4B are integrally moved forward, and 1 bell 48
The upper new stitch L2 is transferred onto the main needle 2. And the first
As shown in Figure 1 (16) and (17), both needles 4B,
2 is released, the main needle 2 is moved rearward based on the action of the bending part 350 of the front knitting drive cam 35,
A new stitch L2, that is, a front stitch is suspended above the hook 2b of the main needle 2.

As described above, with the needle sensing member 127 disposed at the sensing position, after the main needles 2 on the needle bed 1 are sorted back and forth with the manual handle plate, the main needles 2 By introducing the rubber stitches into the front and rear batt guide passages 17° 1B, it is possible to knit rubber stitches with a desired stitch pitch corresponding to the uneven pitch of the manual handle plate or the type of manual needle selection. Further, by introducing all the main needles 2 in the knitting section into the rear butt guide passage 18, knitting of flat knitting can be performed.

Furthermore, when knitting is performed with the moving direction of the carriage 6 set to the right, when the direction switching plate 72 is switched to the forward position, the thread operating lever 59 is moved upward based on the action of the cam groove 79 shown in Figure @5. A cam follower (not shown) is engaged with a second left-right movement cam (not shown) on the lower surface of the third cam ring 32. Therefore, when feeding yarn to the wooden nail 4B or the main needle 2, the yarn head 56 is moved from the rear side to the front side in the carriage movement direction, that is, from the left side to the right side of each needle 4B, 2. There is a difference between

Next, a case will be described in which rubber knitting is performed according to the uneven shape of the selection member 137. When the operation piece 144 is rotated and placed in the position shown in FIG. 8(a).

Based on the action of each of the changing cams 141 to 143, the first sensing member 125 and the needle sensing member 127 are activated as shown in FIG. 8(d).

The needle sensing piece 131 and the needle sensing piece 133 are placed in the non-sensing position shown in FIG. 3, as is clear from FIG. 3. Further, the second sensing member 126 is placed at the sensing position shown in FIG.

In this state, after setting the moving direction of the carriage 6 to the left, when the carriage 6 is moved by one pitch of knitting needles as each cam wheel is rotated 30 to 320 times, as is clear from FIG. The second sensing piece 132 of the sensing member 126 is the selection member 1
37, and the rose 1-2a of one main needle 2 in the bat guide passage 18 is introduced between both the clamping pieces 14 and 15 through the notch 13a of the bat operating body 12. In this state, when the low cam portion 124a of the drive cam 124 faces the cam follower piece 123 of the arrangement changing member 120 as each cam ring 30 to 32 rotates, the wire spring 1
Due to the spring force of the leaf spring 129, which has a stronger spring force than 21, the arrangement changing member 120 is rotated clockwise in FIG. 3 together with the second sensing member 126.
is placed in the position shown in the figure, and the second sensing piece 132 enters the recess 137b of the selection member 131.

Therefore, the gap between the arrangement change member 120 and the upper surface of the carriage 6 is narrowed, and forward movement of the switching plate 96 is prevented, and the switching plate 96 is maintained at the rear position (second position) shown in Figures 3 and 4. be done.

Otherwise, the main needle 20 butt 2a is connected to the needle sensing member 12.
Since the same drive cam selection state as when no detection was detected by 7 is set, the butt actuating body 12 is moved back and forth based on the cam shape of the front knitting drive cam 35, and 1
The wooden nail 4B is moved back and forth based on the cam shape of the cam for moving the main needle back and forth.

Therefore, the front opening can be knitted by the cooperation of both needles 2 and 48.

On the other hand, after the knitting of the front opening is completed, the carriage 6 is again given a leftward feed by the knitting needle pitch, and as is clear from FIG. 2, the second sensing piece 132 of the second sensing member 126 137, and in that state,
As each of the cam wheels 30 to 32 rotates, the lower cam portion 124a of the drive cam 124 moves toward the cam follower piece 1 of the arrangement changing member 120.
23, the downward movement of the second sensing piece 132 based on the spring force of the leaf spring 129 is prevented by the convex portion 137a, so that the spring force of the leaf spring 129 is applied to the arrangement changing member 120. It stops working. Therefore, the wire spring 121
The spring force holds the repositioning member 120 in a position away from the upper surface of the carriage 6, and a wide gap is formed between them through which the upright piece 96a of the switching plate 96 can pass. Thereby, the switching plate 96 is moved to the forward position based on the spring force of the spring 10B.

In this case, the main needle 20 butt 2a is connected to the needle sensing member 121.
Since the same drive cam selection state as when the change was detected is set, the bat operating body 12 is moved back and forth based on the cam shape of the back sight drive cam 36. Therefore, back stitch knitting can be performed.

The selection member 131 has an uneven portion 137b.

Since the stitches 137a are formed alternately, the front and back stitches are alternately knitted as the carriage 6 moves, making it possible to perform 1/1 rubber knitting. Note that the uneven portions 137b, 1
By appropriately changing the arrangement of 37a, it is possible to perform 2/2, 3/3, etc. rubber knitting.

Next, a case will be described in which so-called garter knitting is performed, in which front and back stitches are knitted alternately in each row.

First, using a manual handle plate or the like, place the main needle 2 within the knitting section on the needle bed 1 at a position corresponding to the rear butt passage 1B on the bottom surface of the carriage 6, and place the main needle 2 outside the knitting section on the needle bed 1. The main needle 2 is placed at a position corresponding to the needle stop passage 19 of the lower frame of the carriage 6. Next, a pair of cam pieces (not shown) are placed on the rear edge of the needle bed 1 so as to correspond to the two main needles 2 located outside of the two main needles 2 at both left and right ends of the knitting section. do.

Next, when the operation piece 144 is rotated and placed in the position shown in FIG. 10 (11), the second sensing member 126 and the needle sensing member 127 are
is placed at the non-sensing position shown in FIGS. 10(C) and 10(b). Meanwhile, the first sensing member 125 is placed at the sensing position shown in FIG. 10(d).

In this state, when the direction switching plate 72 is placed in the rear switching position shown in FIG.
4 is rotated, and one end of the rotating member 84 is separated from the second sensing piece 131 as shown in FIG. And each cam wheel 3
When you rotate 0 to 32, the rightmost main needle 2 of the knitting section
is introduced into the bat operating body 12. In addition, the drive cam 124
When the low cam portion 124a faces the cam follower piece 123 of the placement changing member 120, the spring force of the leaf spring 128 causes the placement changing member 120 to be placed in the lower position shown in FIG. A sensing piece 131 protrudes into the body measurement passage 19. Therefore, the switching plate 96
It is placed at the rear position (second position) shown in the figure.

In this way, when the rotating member 84 is separated from the first sensing piece 131, the same cam selection state as when the recess 137b of the selection member 137 is sensed by the second sensing member 126 is set. Through the cooperation of the rightmost main needle 2 and the first wooden nail 4B, the front opening can be knitted, and by continuing to rotate each of the cam wheels 30 to 32 in this state, the left side of the carriage 6 can be knitted. With the direction movement, it is possible to knit one row of front rows.

On the other hand, after the above-mentioned knitting is completed, the linking pin 86 of the rotating member 84 shown in FIG.
When engaged, the rotating member 84 is rotated in a predetermined direction by the cam action, and the end of the first sensing piece 131 is covered by the rotating member 84, and the direction is switched via the pin 84a. The plate 72 is moved forward. As a result, the arrangement position of the rotary lever 80 is changed, and the biasing direction of the shaft 65 by the coiled spring 81 is switched to the right. When each of the cam wheels 30 to 32 continues to rotate, the carriage 6 is moved to the right this time, and the main needle 2 at the leftmost end of the knitting section is moved to the main needle 2.
2a is introduced into the bat operating body 12. Then, the lower cam portion 124a of the drive cam 124 is connected to the arrangement changing member 120.
When facing the cam follower piece 123, the downward movement of the first sensing piece 131 is prevented by the rotating member 84, so the spring force of the wire spring 121 causes the placement changing member 120 to separate from the upper surface of the carriage 6. A wide gap is formed between the two.

In this case, since the switching plate 96 is moved through the gap to the forward position, the same drive cam selection state as when the convex portion 137a of the selection member 131 is sensed by the second sensing member 126 is set. be done. Therefore, the back stitch can be knitted using the leftmost main needle 2, and the carriage 6 is moved to the right by rotating each of the cam wheels 30 to 32, and the back stitch is knitted to the next row of the front row of the one row. You can knit a row of back stitches.

After this knitting is completed, when the linking pin 86 of the rotating member 84 engages with the right cam piece (not shown) on the needle bed 1, the rotating member 84 is rotated in a predetermined direction by the cam action. The end of the second sensing piece 131 is moved away from the first sensing piece 131, and the second sensing piece 131 is allowed to move downward. As a result, the above-mentioned front knitting state can be set again, and as the carriage 6 moves leftward, one row of front knitting can be performed again on the next row of the one row of back rows. can.

Effects As detailed above, the first invention of this application includes a carriage with a single butt guide passage for individually guiding the butts of the knitting needles of the needle beds sorted to different positions, and a pair of butt guide passages. The present invention is different from the conventional one by being equipped with a control body that senses the knitting needles guided to at least one of the butt guide passages at a predetermined position and controls the position of the switching body that switches between the back stitch and the front stitch. In contrast, there is no need to use a needle selection device on the needle bed; instead, the knitting needles on the needle bed can be sorted in advance into two groups, front and back, by hand or with a manual handle plate, etc., and the sorting position can be easily adjusted. A mixed pattern of front and back stitches can be easily knitted according to the requirements.

Further, a second invention of this application is that, in addition to the pair of bat guide passages and the control body, the carriage is further provided with a changing device that can change and arrange the control body between a sensing position and a non-sensing position with respect to the knitting needles. Moreover, the excellent effect is that it is possible to easily switch knitting according to the sorting position of the knitting needles and knitting that is unrelated to the sorting position.
