Next, the operation of the needle selection device of the hand knitting machine constructed as described above will be explained.

Now, FIG. 3 shows that the card supporting member 13 supporting the pattern card 14 and the arrangement switching member 40 are moved to the rightmost reference position based on the index 45 on the needle bed 1 by the manual operation part 42a of the connecting member 42. This indicates the state in which the

In this state, one signal string 14 on the ζ pattern card 14
Each recording signal 14b in a is arranged correspondingly to the reading protrusion 15a of the 24 main signal reading members 15, and the allowable recess 40c at the lower end of the arrangement switching member 40 is arranged corresponding to the connecting part 15c of the main signal reading member 15. 8
Excluding the book auxiliary reading member 115 (main signal reading member 15
Only a rising reading operation is permitted.

Therefore, each recording signal 14b in one signal row 14a on the pattern card 14 is repeatedly recorded by the main signal reading member 15 etc., with a continuous group of 24 knitting needles at a predetermined position on the needle bed 1 as one unit. We will deal with it.

When the carriage 26 is slid in the direction of the arrow in FIG. 6 in this state, the endless belt 25 on the needle bed 1 side runs in the same direction, and at the beginning of its travel, the rotating shaft 22 moves clockwise in FIG. The pressing rod 24 is rotated, and the main signal reading members 15 located at the upper position are lowered, so that all the main signal reading members 15 are aligned at the lower position indicated by the chain line -Cyr in the figure.

Then, the card feed shaft 10 is rotated by one pitch of the signal train 14a via the ratchet wheel 11, etc., and the pattern card 14 is fed to a new signal train with each recorded signal 1 of 14&.
4b corresponds to the reading protrusion 15a of each main signal reading member 15, the rotating shaft 22 is rotated counterclockwise, and the pressing rod 24 returns to the upward position.

As a result, each of the reading protrusions 15a reads the pattern card 14.

Among the knitting needles 4 that have been lowered in this way, those corresponding to the knitting needle locking pieces 7a of the pattern plate 7 that have been moved to the above-mentioned operating position are locked by the locking pieces 7a and the press cam 31 is suppressed. Even after being released from action, the knitting needles are retained in the lower position, and those corresponding to the knitting needle locking pieces 7a of the pattern plate 7 placed in the inactive position are locked to the locking pieces 7a. After being released from the pressing action of the pressing force 41, the elastic member 50 is returned to the upper position by the elastic force.

Then, the butt 4a of the knitting needle 4 held in the lower position passes through the notch 33e of the sorting and enlarging cam 33 as the carriage 26 slides, and immediately after that, the knitting needle locking piece for the knitting needle 4 With the release operation of 7a, it is returned to the upper position, and after being moved forward along several inclined guide surfaces 33b, it escapes from the lower surface of the carriage 26,
Moreover, the rose (4a) of the knitting needles 4 disposed at the upper position is as follows:
After being moved rearward along the inclined guiding surface 33a inside the sorting and enlarging cam 33, it escapes from the lower surface of the carriage 26.

Therefore, each knitting needle 4 participating in knitting is sorted into two positions, front and rear, on the needle bed 1, and each knitting needle 4 has a predetermined predetermined value corresponding to each recorded signal 14b in one signal string 14a of the pattern card 14. The type of needle selection based on the recorded signal 14b is repeatedly displayed, with each needle group at the position as one unit.

Then, when the carriage 26 is slid in the direction opposite to the arrow in FIG.
Two-color simultaneous knitting and other knitting such as tuck knitting are performed as the yarn is fed from the yarn feeders at two positions, front and back, relative to the hook of the knitting needle 4.

Next, when changing the target position of the knitting needle group in which the selected needle type appears based on each recorded signal 14b in the signal train 14a of the pattern card 14, the two-type signal reading member 15, 115 is pressed. The card support member supports the pattern card 14 based on the indicator 45 on the needle bed 1 by the manual operation part 42a of the connecting member 42 shown in FIGS. 1 and 3 while being moved to the lower position by the rod 24. When the pattern card 13 and the arrangement switching member 40 are moved a desired amount to the left from the reference position in FIG.
Each recording signal 14b in a is arranged corresponding to the reading protrusion of 24 consecutive reading members 15 and 115 across the main signal reading member 15 and the auxiliary reading member 115,
The allowable recesses 40c at the lower end of the arrangement switching member 40 are arranged corresponding to the three series of both types of signal reading members 15 and 115.

Therefore, in this state, one signal string 1 on the pattern card 14
Each recording signal 14b in 4a is transmitted via the two-type signal reading members 15, 115 to the number of knitting needles (1 to 8) corresponding to the amount of movement of the pattern card 14 from the group of knitting needles at the predetermined position on the needle bed 1. ) The group of 24 knitting needles at the position moved to the left by the distance is treated as one unit, and the process is repeated.

As a result, when the knitting needle 26 is slid in this state, each knitting needle 4 participating in knitting is sorted into two positions, front and rear, by the pressing cam 31, the sorting enlargement cam 33, etc. on the lower surface of the carriage 26, as in the case described above. For those knitting needles 4, the needle selection pattern based on each recorded signal 14b of the signal string 14a on the pattern card 14 is set to a group of knitting needles that are at a position moved by multiple needles from the needle selection operation described above. appears repeatedly.
