(Fig. 1) Reference numeral 21 denotes a moving body that moves in the direction in which the knitting needles 7 are arranged on the needle bed 2, and there are sorting member device spaces 22.2 on both left and right sides of the moving body.
2a is provided, the central part has a rear edge 24 slightly behind the guide rail 4, a front edge 25 near the front edge of the face plate forming the needle groove 3 of the needle bed 2, and both side edges the device space 22.
A window hole 23 for connecting the carriage is provided at the edge of the rear edge 22a, and small connecting protrusions 26, 26a are left on both left and right sides of the rear edge 24.

On each rear lower surface of the device space 22.22a, an inverted rectangular sliding piece 27° 27a that fits into the guide rail 4 is fixed, and on each front part thereof, an inclined support piece 28° 28a protrudes downward. A movable piece 30.30a that rubs the front edge of the needle bed 2 is attached to the lower front surface of the needle bed 2, and a small connecting protrusion 26.26a and a portion immediately in front of the front edge 25 are formed. A connecting pin 31 serving as a means for connecting the carriage is attached to each upper surface at the center in the left-right direction.

(See Figure 4). A sorting member 32 is provided on the upper surface of the device space 22.22a for sorting the butts 8 of the knitting needles 7 back and forth according to the signals of the signal string of the signal card 13.

Both the left and right sorting members 32 have the same well-known configuration.

The outline is as shown in Figure 3, and the equipment space 22
．． 22a rear upright shaft 33 and inclined support piece 28.28a
A spool 35 with a gear 36 that meshes with the rack 6 fixed at the bottom thereof is loosely fitted into the upright shaft 33, and a gear that meshes with the gear 36 is fitted onto the slant shaft 34. The spool 42 with the spool 43 fixed at the bottom is fitted loosely,
The same number of signal memory pieces 37 as the card reading pieces 15 are arranged at equal intervals on the outer periphery of the upper part of the spool 35 and supported by a shaft 40.
It is configured to swing between two positions: an inactive position indicated by the chain line, which moves outward, and an active position, indicated by the solid line, which moves inward.

On the outer periphery of the spool 42, the same number of knitting needle selection pieces 44 as the signal memory pieces 37 are arranged at equal intervals, and the upper ends of the needle selection pieces 44 move inward to the upper elastic engagement ball 47 at the non-acting position indicated by the chain line and outward. It has a structure that swings between two positions, including an operating position.

When the movable body 21 moves on the needle bed 2, the selection member 32 provided on the selection member device space 22 or 22a on the front side of the movement direction selects the knitting needles. 7 is sorted forward and backward, and the sorting member 32 on the rear side in the same movement direction stores the mode of sorting the knitting needles at the time of the next turning movement according to the signal string of the signal card 13.

To explain the above specifically, as the movable body 21 moves in one direction on the needle bed 2, the needle selection member that has stored the signal of a certain signal train of the signal card 13 by the previous movement in the other direction,
This time, it is on the front side in the moving direction, and due to the engagement of the gear 36 with the rack 6, the spool 35 rotates together with the signal memory piece 37, which was placed in the solid line position or the chain line position according to the signal of the signal train of the signal card 13 during the previous movement. At the same time, the spool 42 and the knitting needle selection piece 44 rotate due to the engagement of the gear 43 with the gear 36.

Therefore, the knitting needle selection piece 44 is unable to scoop up the pressure receiving piece 45 by the signal transmitting portion 39 of the signal storage piece 37 which is in the position indicated by the chain line, and remains at the working position indicated by the solid line, and the contact plate 46 is moved to the knitting needle butt 8. The pressure receiving piece 45 is scooped up by the signal transmitting portion 39 of the signal memory piece 37 which is in the solid line position, and is swung to the non-acting position as shown by the chain line, thereby causing the contact plate 46 to be in contact with the rear side. Since the knitting needles have moved to a position where they do not contact the butt, needle selection is performed in which the knitting needles 7 corresponding to the contact plates 46 located at the solid line position are moved forward as the spool 42 rotates.

Then, while the sorting member 32 rotates, the card reading piece 1
When passing in front of row No. 5, the signal card 13 remains the same as before, so there is no change in the memory of all signal memory pieces 37 and the arrangement of the solid lines and chain lines of the knitting needle selection piece 44, and the selection member 32 has finished passing in front of the row of card reading strips 15, and just before the sorting member 32 on the rear side in the moving direction passes in front of the row of card reading strips 15, the signal card 13 is sent to convert the signal string, At the same time, each signal memory piece 3T of the sorting member 32 on the rear side in the moving direction is aligned to the chain line position to erase the memory, and the knitting needle selecting piece 44 is aligned to the solid line position.

For this reason, all the signal storage pieces 37 rotate and push the pressure-sensitive surfaces 17 of the corresponding card reading pieces 15 with the protrusions 38, and the card reading pieces 15 with the signal touch pieces 16 corresponding to the holes of the signal cards 13 are pressed. The protrusion 38 is placed on the pressure-sensitive surface 17 of the card reading piece 15, which makes the signal touch piece 16 correspond to the non-perforated part of the signal card, by swinging it as shown by the chain line, without changing the posture at the position indicated by the chain line. The contacting signal memory piece 37 is pushed back by the protrusion 38 and becomes the solid line position.

When these rotate and match with the corresponding knitting needle selection pieces 44, the selection pieces 44 are made to have one part that does not swing and the other part that swings, as described above, so that the contact plate 46 is placed in the solid line position and the chain line position. , thereby memorizing the type of needle selection to be performed the next time the movable body 21 moves.3 The above is an example of the already well-known sorting member of the sorting member provided in the movable body, but the sorting member 32 of the present invention , 32 may provide the moving body 21 with a sorting member other than the above.

The movable body 100 moves on the needle bed 72 accompanied by the knitting carriage 131 or the stitch transfer carriage 141, and during the movement, the belt 85 is rotated between 84 and 84a to change the needle position pulse disk. 86 and the needle position code disk 89 are linked.

The abutment pins 127 on the needle bed corresponding to the connecting plates 124 on both sides are connected to the pulley 8 by the movable body 100 via the belt 85.
4 rotates four times, collides with the sliding slope 125 and alternately pushes the connecting plate 124 backward so that it does not engage with the second connecting plate 135 or 145 of both carriages 131, 141.
After that, the carriage 131 or 141 moves to the moving body 100.
For example, when moving back from the left to the right, the connecting plate 1 on the right side
24 with the second connecting plate 135 or 145, and the movable body 100 is moved in conjunction again.

Therefore, the number of times that the 64 light-transmitting slits 87 of the needle position pulse disk 86, which rotates four times by one movement of the movable body 100 on the needle bed 72, corresponds to the light receiving element 88a is 256 times.

However, since there are 200 knitting needles 80 and 200 jacks 82 arranged in a row on the needle bed 72, they correspond to the first 28 needle position pulses and the last 28 needle position pulses generated during one movement of the moving body 100. There are no knitting needles or jacks.

The pitch of the horizontal rows of the 32 discharge ports 160 on the pattern card 158 is the same as the pitch of the stitches of the knitted product that has shrunk due to the elasticity of the knitting yarn, or it is displayed by expanding or contracting it appropriately, and the model pattern 161 is displayed on the pattern card 158. represents.

(Figure 17).

The model pattern can be changed to 32 by operating the selection knob 178.
Using 64, 128, or 256 knitting needles, it is realized on a knitted product at a magnification of 1x, 2x, 4x, or 1x.

Of course, in knitting needle selection on the premise that stitch transfer is performed using the stitch transfer carriage 141, one discharge port 160 is made to correspond to one knitting needle, and the necessary discharge ports are completely filled out.

(Figure 18).

FIG. 19 shows a block diagram of the signal storage and readout control circuit and other functional units included in the pattern storage output device 151.

The device 151 drives a scanning pulse motor 172 for scanning a model pattern 161 using a spiral transparent slit 173 of a scanning cylinder 171, and a stage feeding pulse motor 151.
The winding 1 of the sorting member 111 included in the moving body 100
20 is controlled by the operation angle of the pattern unit selection knob 178 and the opening/closing switch piece 128 (FIG. 9), which is operated by the belt 85 which changes the running direction when the moving body 100 changes the moving direction. It also has various functions for driving the scanning cylinder 171 at the beginning of feeding the pattern card 158 and performing initial alignment using the alignment slit 174.

Below, we will explain the initial positioning, the erasure of old information stored therein, and the operation of the pattern unit selection knob.

◎ Even if the initial positioning pattern card 158 is supplied between the guide plates 163 and 164, the portion representing the model pattern 161 is sent to the position corresponding to the transparent slits 165 and 166 by rotation of the hand-feed rotary grip ring 156. (This position can be confirmed by opening the guide plate 163 with the hinge shaft 167), scanning cylinder 1
Correct pattern information cannot be scanned unless the starting ends of the 11 helical transparent slits 173 match the transparent slits 165 and 166. Therefore, the initial positioning is performed so that the initial alignment slit 174 matches the transparent slits 165 and 166. At this time, the rod-shaped lamp 169 is turned on before the main drive switch 181 is turned on, and the small photoreceptor 17 is turned on.
The bright/dark discrimination circuit 187 having circuit element 6 is closed.

At this time, the small photoreceptor 176 is not driven due to the mismatch of the initial positioning slits 174, and since the circuit 187 is at a low potential, a high potential signal is applied to the AND circuit 183 through the inverting input terminal.

Then, when the main drive switch 181 is closed, the single pulse generation circuit 182 is driven only at that moment, and the AND circuit 1
83, the AND circuit 183 is opened and a trigger signal is given to the set input terminal S of the first flip-flop circuit 184, and the output of the circuit 184 drives the first continuous pulse generation circuit 185. Then, in order to give a continuous pulse signal to the scanning pulse smoke 172 via the OR circuit 186, the scanning cylinder 171 rotates the initial positioning slit 174 to a position where it matches the transparent slits 165 and 166, and the small photoreceptor 176 turns into a lamp. At the same time as the light is received, the light/dark discrimination circuit 187 is converted to a high potential.

Therefore, the first flip-flop circuit 184, which has one end of the circuit 187 connected to the reset input terminal R, is reset, and the driving of the pulse motor 172 by the first continuous pulse generation circuit 185 is stopped, and the alignment is automatically performed as described above. be processed accordingly.

◎ Erasing information memory Memory 202R of computer 200.

It is harmful when the information of the pattern card 158 supplied last time is stored in 202L.

Therefore, as described above, the single pulse signal generated when the 7 drive main switch 181 is closed and the single pulse generation circuit 182 is driven is also applied to the write control circuit 201 to erase the information stored.

◎ The operation of the pattern selection knob 178 The information on the model pattern 161 on the pattern card 158 is not started at the same time as the completion of the initial positioning, but it is necessary to determine the magnification realized by the knitting needles of the model pattern 161 before that. The magnification is the pattern selection knob 178
This is done by circuit operation.

The above-mentioned knob is used to calibrate the 32 horizontal rows of the outlet ports 160 of the pattern card 158 using 32 to 256 knitting needles as described above.
This controls the selection of enlarging to 2x, 4x, or 1x, and when the magnification is other than 1x, it is necessary to increase the number of knitting needles in the stitch direction and row number direction.

That is, when the magnification is the same, information at one point P in the approximate center of the outlet 160 is scanned as shown in FIG. 20, and when the magnification is double, information is scanned at two points in the horizontal direction of the outlet 160 as shown in FIG. is scanned twice for a total of four points, and when the number of times is four, the information for each four points in the horizontal direction of the outlet 160 is scanned four times for a total of 16 points and stored.

This information is stored in the drive circuit of the stage feed pulse motor 157, the second continuous pulse generation circuit 196 that controls the drive of the scanning pulse motor 172, and the write control circuit 201.
A pulse generation control circuit 193 and a pulse control circuit 198 are respectively inserted between the former circuit 193 and
In this case, the number of drive pulses to be generated to be driven by the trigger pulse applied each time the moving direction of the moving body 100 changes and to be applied to the stage feeding pulse motor 157 is set by the pattern unit selection knob 178 to 1, 2, 4, or 8. The latter circuit 198 outputs one pulse when the pulse signal of the second continuous pulse generation circuit 196 is 8, 4, 2, or 1. Write control circuit 1
98 is controlled by a pattern unit selection knob 178.

The photoreceptor 91-1 of the needle position code disk 89 determines which knitting needle (jack) the information stored in the memory 202R or 202L is read out by the drive of the write control circuit 201 and is applied to.
The gate control circuit 204 which connects the terminals 91-8 to 91-8 and outputs the outer code is selectively operated by the pattern unit selection knob 178.

The photodetectors 91-1 to 91-8 are attached to the moving body 100 as described above.
As the knitting needles (jacks) move on the needle bed 72, they rotate once, and the gate control circuit outputs the array position code "0 to 255" of the knitting needles (jacks).
are output sequentially or in reverse order, and the read control circuit 203 reads out the address "0" from the memory 202R or 202L.
255'', but if the knob 178 is set to the rightmost angle at the bottom of the gate control circuit 204 in FIG. After being cut, the output of the position code "0 to 31" is repeated, and by sequentially changing the angle to the left, "0" is output.
~63'' and ``0~127'', and when the angle is at the leftmost position, a position code of ``0~255'' is output.

However, each position code is memo IJ-202R, 202
This corresponds to each address of L.

Therefore, for example, when the above-mentioned position codes "0 to 63" are sequentially given to the readout control circuit 203, the addresses "0 to 63" corresponding to the position codes of the memo IJ-202R are sequentially opened to read out the stored information. As the mobile object 100 moves, “0”
Since the output of the position code "~63" is repeated four times, the reading of the stored information is similarly repeated four times, thereby increasing the unit number of knitting needles that embody the model pattern 161 on the knitted product to 64. Make it.

By operating the pattern selection knob 178 as described above, model pattern 1 is selected.
Scanning and writing/storage of the information 61 based on the required magnification, reading of the stored information, and sorting of the jack 82 and knitting needle 80 based on the required magnification become possible as will be described in detail below.

Model pattern 1 is written into one of the memories 202R or 202L of the computer 200 by the write control circuit 201 as the moving body 100 moves back and forth, as will be described in detail later.
61 information is written, and the other stored information is read out by the read control circuit 203.

Such write storage and storage read operations are performed by the drive circuit 188.
By driving the write control circuit 201 and the read control circuit 203 when the
The drive circuit 188 controls writing of information to 2H and reading of information stored in the memo IJ-202L.
By driving both circuits 20L203 when holding the memo IJ-202L and memo 'J-20
Controls reading of 2H storage information to clarify its division.

FIG. 19 shows a model pattern of each of the pulse generation control circuit 193, pulse control circuit 198, and gate control circuit 204 represented on the pattern card 158.
The pattern unit selection knob 1 is set so that six knitting needles (there are only 200 on the needle bed 72) can be realized at a double magnification.
78 is an example of the state in which it is operated.

In the figure, a drive control circuit 188 is connected to a potential inverting inverter 190 connected to a high potential bias circuit 189 that is grounded or ungrounded by an on/off switch piece 128 that is activated by changing the moving direction of the moving body 100 and the running direction of the belt 85. Since it is connected, the scanning cylinder 1 mentioned above
When the belt 85 is moved to the right together with the movable body 100 after the initial positioning of the pattern card 71 is automatically performed along with the feeding of the pattern card 158, the opening/closing switch piece 128 is turned on as indicated by the solid line, and the inverter 190 turns on the belt 85. Simultaneously with converting the drive control circuit 188 to a high potential, the trigger pulse generation circuit 191 is driven, the AND circuit 192 is opened, and a trigger is applied to the set input terminal S of the pulse generation control circuit 193 and the second flip-flop circuit 195.

The pulse generation control circuit 193 sends out one pulse to drive the stage feeding pulse smoke 157.

As described above, this pulse motor 157 is driven by 8 pulses to feed the pattern card 158 corresponding to the length of the chiro 160 in the vertical direction.
It produces a feed of 160%.

Then, when the pattern card 158 has been fed, the second flip-flop circuit 195 is set by a trigger delayed by the delay circuit 194, and the output of that circuit drives the second continuous pulse generation circuit 196, and the continuous pulse 1 by giving the signal to the pulse control circuit 198
One pulse signal is applied to the write control circuit 201 for each pulse.

The control circuit 201 is given a command to write the information of the model pattern 161 into the memo IJ-202R by the high potential of the drive control circuit 188, and on the other hand, the light-transmitting slit 165
, 166, 173, the pattern card 158 is scanned by focusing the light emitted from the rod-shaped lamp 169 into a spot light, so when the pulse control circuit 198 applies the output pulse as described above, the memo IJ-202H Write.

Further, the continuous output pulses of the second continuous pulse generation circuit 196 are delayed very slightly by the delay circuit 197, and a pulse signal is applied to the scanning pulse motor 172 through the OR circuit 186 to continuously drive the scanning cylinder 171. The matching points of the spiral light-transmitting slit 173 and the light-transmitting slits N65 and 166 are sequentially moved in the lateral direction.

The memory 202R and 202L have 256 information write addresses "0 to 255", and when an output pulse is applied from the pulse control circuit 198, the memory 202R is scanned with a spot hole passing through the coincident point of the transparent slits 165 and 173. If the information on the model pattern 161 is black, “1”;
If it is white, digital records of "0" are sequentially written to the addresses and stored.

Therefore, the pulses generated by the second continuous pulse generator 196 are also applied to the reset signal generator circuit 199.
99 accumulates and records the number of applied pulses, and at the same time as counting 256 pulses, generates a reset signal and applies it to the reset input terminal R of the second flip-flop circuit 195 to drive the second continuous pulse generator 196. stop.

The above 256 pulses are generated at the time when the scanning cylinder 171 rotates once and one scan of the pattern card 158 is completed, and the memo IJ-202R has information written to all 256 addresses. Intensive memorization is done.

If the moving body 100 is moved to the left, the opening/closing switch piece 1
28 is turned off as the rear part of the belt 85 moves to the right, changing the drive control circuit 188 to a low potential, and at the same time driving the trigger pulse circuit 191 to trigger the pulse generation circuit 193 to generate pulses in the circuit 193. The step feeding pulse motor 157 is driven by the pattern card 158.
is sent for a length of 160% of Ciro, and then the information is sequentially written to address 256 of Memo 'J-202L using the same operation as above.

Further, as the moving body 100 moves to the left, the needle position code disk 89
rotates, and along with light reception by the photoreceptors 91-1 to 91-8, a needle position code output is input from the gate control circuit 204 to the latching circuit 205, and the jack 82 with the corresponding code is connected to the sorting member 1.
11, the light receiving element of the needle position pulse disk 86 is driven as described above to apply the needle position pulse to the latching circuit 205 and read out the needle position code signal to the control circuit 203. When the black information "1" of the model pattern 161 is read out, the information signal is sent to the AND circuit 206 and the amplification circuit 207. The winding 120 is driven 1 through
While configuring a magnetic circuit, attraction sorting is performed up to the rear edge of the second guide cam 106.

When the white information "0" is read, the jack 82 is moved along the front edge of the guide cam 104 without giving any sorting action, and the sorting mode is expanded by the sorting cam 109. is the sorting cam 10 as described above.
The jack 82 advanced by 9 strikes the rear side of the bat 81, and the knitting needles passing through the rear side of the lowering cam 140' of the knitting carriage 131 and escaping out of the carriage are sorted back and forth according to the arrows c and d.

The selected knitting needles embody the model pattern 161 on the knitted product by the knitting operation when the carriage 131 moves in the opposite direction together with the movable body 100.

When operating the pattern unit selection knob 178 to store the model pattern 161 at a magnification of 1x, 2x, 4x, etc.,
Every time a trigger is applied from the trigger pulse generation circuit 191 to the pulse control circuit 193, eight pulses are generated when the magnification is 1x, 4 when the magnification is 2x, and 2 pulses when the magnification is 4x. The pattern card 158 is sent by a motor 157 at different moving distances to scan each horizontal point, two points, and four points in the discharge port 160 as shown in FIGS. Remember information.

Therefore, the amount of information that can be scanned and stored is 32 for the same size, 64 for double, and 128 for quadruple, so Memo IJ-2
256 addresses of 02R1 or 202L contain “0
~31'', 10~63'', and ``0~127'' are written in sequence, and the others are left blank.

On the other hand, the needle position code output from the gate control circuit 204 is 3.
Since the knitting needle code outputs of "0 to 31", "0 to 63", and "0 to 127" are repeated corresponding to 2, 64, or 128 jacks 82, the memory by the readout control circuit 203 is The reading of information is also repeated six times, four times, and twice, and the selection of the jacks 82 is repeated in the same manner by driving and not driving the winding 120.

Therefore, the model pattern 161 is realized on a knitted product with groups of 32, 64, and 128 knitting needles.

The connecting plates 135 and 145 of both carriages 131 and 141 can be moved to a forward inactive position where they do not engage with the connecting plate 124 of the moving body 100.

For this purpose, as shown in FIG. 11, the stitch transfer carriage 141 placed at the working position behind the connecting plate 145 is connected to the movable body 100, and the knitting carriage 141 placed at the working position behind the connecting plate 135 is connected to the moving body 100. Needle bed 2 along with 131 alone
It can also be used by moving it relationally above.

Stitch transfer between knitting needles involves sorting every few knitting needles forward as knitting needles for stitch transfer, and transferring the stitches to the hooks of the knitting needles adjacent to the selected knitting needles. As shown, the knitting needles to be sorted are clearly indicated by filling out the outlet.

Using this card, perform Jack 82 at the same magnification.
The operation of selecting the knitting needles 80 itself is the same as described above, so the explanation thereof will be omitted.
