As shown in FIGS. 2 and 4, in the knitting machine main body 1, eight handle plates 17 are arranged in the front and back direction for controlling needle selection in cooperation with the sorting cam mechanism 10 on the knitting carriage 8. The knitting needles 4 are arranged in an overlapping state and can be moved individually in the direction in which the knitting needles 4 are arranged. At the top of each handle plate 17 is a hook-shaped projection 17a for locking knitting needles.
Individually, every eight knitting needles 4 are formed protrudingly. In this embodiment, the hook-shaped protrusion 17a corresponding to the number 100 knitting needle 4 on the left side is attached to the handle plate 17A.
The handle plate 17B also has a hook-shaped protrusion 17a corresponding to the knitting needle 4 of No. 99 on the left, and the handle plates 17C, 17D, 17E...
...17H, 17A, 17B, etc. are repeated so that the handle plate 17H has a hook-shaped projection 17a corresponding to the knitting needle 4 of No. 100 on the right side. Furthermore, due to the action of a spring 18 hung on the left end of each of the handle plates 17A to 17H, the hook-shaped protrusion 17a is always arranged between the knitting needle 4 adjacent to the left side without corresponding to the lower part of the knitting needle 4. When the knitting needle is moved to the right against the action of the spring 18, it can assume an active position in which the hooked protrusion 17a can lock the knitting needle pushed down. There is.

As shown in FIGS. 2 to 4, an electromagnet group 19 is provided inside the rear side of the knitting machine main body 1, and includes 16 electromagnets SLO to 9, which corresponds to twice the number of the handle plates 17,
It is more familiar from A to F. A rocking plate 20 is supported directly above each of the electromagnets SLO to F so as to be movable up and down using their rear ends as a fulcrum.
is urged to move in the direction of being attracted by the electromagnets SLO to F. The knitting machine main body 1
Sixteen U-shaped rods 23 are penetratingly supported on the inner support frame 22 so as to be movable up and down on the rear legs 23a, and the front legs 23b can swing in a horizontal plane around each rear leg 23a. ing. A rising spring 24 is brought into contact with the lower surface of each U-shaped rod 23, and each U-shaped rod 23 is biased upward by its elastic force.
Normally, the upper end of the rear leg 23a is in contact with the lower surface of the front end of the swing plate 20.

Inside the cover 3 on the side where the right pulley 14 is arranged, a rotation shaft 25 is rotatably supported on the knitting machine main body 1 so as to extend in the left-right direction above the front leg 23b of the U-shaped rod 23. The right end portion thereof is coupled to the right pulley 14 via gears 26 and 27 so as to be interlockable. In this embodiment, the rotation shaft 25 is rotated three times by one rotation of the pulley 14, or in other words, the rotation shaft 25 is rotated once by the carriage sliding of 16 knitting needles 4. The speed increasing ratio of the gears 26 and 27 is set to . On the outer periphery of the rotation shaft 25, 16 lateral operating cams ACO to F are formed with their phases sequentially shifted by an angle (22.5 degrees) corresponding to one pitch of the knitting needles 4. The length is determined to be an angular range corresponding to approximately four pitches of the knitting needles 4, and the needles are arranged in a spiral so as to go around the rotating shaft 25 as a whole. Further, on the outer periphery of the rotation shaft 25, 16 push-down cams BCO to F are formed in a one-to-one relationship with each of the lateral operation cams ACO to F, with a phase shift of 180 degrees with respect to each of the cams.
As is clear from FIG. 2, the shape of the cam surface that bulges out on each outer circumferential surface gradually bulges from near the base edges on both sides of the corresponding lateral action cams ACO to F, and extends to approximately two pitches of the knitting needles 4. It is defined to have a top surface over a corresponding angular range.

Moreover, each push-down cam BCO to F of the rotation shaft 25 is
Each U-shaped rod 23 is brought into contact with the upper end of the front leg 23b of the corresponding U-shaped rod 23, and is lowered by the action of the cam surface against the elastic force of the rising spring 24, until it reaches the position of the top surface of the cam. The rear leg 23a is pushed down to the lower position shown in FIG. 2, that is, to a position where the upper end of the rear leg 23a is slightly separated from the lower surface of the front end of the swing plate 20. For example, when the electromagnet SL is cut off, as the rotation shaft 25 continues to rotate, the elastic force of the rising spring 24 overcomes the biasing force of the tension spring 21, so that the U-shaped Shape 23 is the push cam
While returning from the lower position shown in FIG. 2 to the upper position along the circumferential surface of BC, the front end of the swing plate 20 is floated. At this time, the front leg 2 of the U-shaped rod 23
3b enters the interlocking locus of the transverse action cam AC, and as the rotation shaft 25 continues to rotate, the transverse action cam AC
Under the action of the horizontal cam surface, the front leg 23b swings around the rear leg 23a. On the other hand, when the electromagnet SL is energized, the oscillating plate 20 is attracted and held by the electromagnetic force, and the lifting spring 2
The upward return of the U-shaped rod 23 based on the action of 4 is prevented, and the U-shaped rod 23 is retained in the lower position. Therefore, even if the rotation shaft 25 continues to be rotated, the front leg 23b of the U-shaped rod 23 will not be able to operate the horizontal operation cam.
It is located below the movement locus of AC and is not affected by the action of that cam AC.

As shown in FIGS. 2 and 4, 16 movable rods 28 are swingably penetrated and supported in the support frame 22 at their intermediate portions, corresponding to the front legs 23b of each U-shaped rod 23. The swinging motion of the front leg 23b of the letter-shaped rod 23 is transmitted to a predetermined part of the handle plate 17, and the handle plate 17 is moved from the needle selection non-active position to the active position against the action of the spring 18. It is inserted into the operating hole 17b of the handle plate 17 and is operatively connected thereto.
In addition, the number of moving rods 28 is determined to be 16, which is an integral multiple of 8, which is the number of handle plates 17, so the number of moving rods 28 connected to each handle plate 17 is two. , out of the total number of arrays, one every seven is connected to the handle plate 17 in an array order. Then, as shown in FIG. 4, the moving rod 2 corresponding to the handle plate 17 outside the specified position
The front end of the handle plate 8 is inserted into a laterally elongated play hole 17c formed in the handle plate 17, and is operationally irrelevant.

That is, in this embodiment, the handle plate 17A
To the handle plate 17B, two moving rods 28 corresponding to the electromagnets SLO, 8 are operatively connected, and to the handle plate 17B, two moving rods 28 corresponding to the electromagnets SL1, 9 are connected.
Similarly, the handle plate 17c has one corresponding to SL2, A, and the handle plate 17D has one corresponding to SL3, B.
The handle plate 17E has one corresponding to SL4, C, the handle plate 17F has one corresponding to SL5, D, the handle plate 17G has one corresponding to SL6, E, and the handle plate 1
7H is operatively connected to those corresponding to SL7 and F, respectively.

In this embodiment, the handle plate 1
7. A needle selection device 29 is constituted by an electromagnet group 19, a sorting cam mechanism 10 on the carriage 8, etc., and a needle selection arrangement is made in the knitting needle group by controlling energization/disconnection of electromagnets SLO to F based on knitting pattern information to be described later. It is beginning to be realized. That is, in FIGS. 3 and 4, when the front linear portion of the endless belt 15 is connected to the knitting carriage 8 and is moved integrally therewith, for example, to the right, the right pulley 14 moves as shown in FIG. The rotating shaft 25 is rotated in the direction of the arrow in the figure, and each of the lateral operating cams ACO to F is located on the right side of the corresponding U-shaped rod 23 compared to the one located on the left side. It acts sequentially towards
The effect is transmitted to the neighboring knitting needles one by one in relation to the carriage sliding of one knitting needle 4.
Furthermore, when the carriage 8 is slid to the left, the effect spreads from the right side to the left side. Therefore, by controlling the energization and disconnection of the U-shaped rods 23 and the corresponding electromagnets SLO to F, the vertical displacement of the U-shaped rods 23 is sequentially selected to be in contact with the lateral operation cams ACO to F or not. In response to this, the needle selection control operation of leaving the handle plate 17 in the needle selection inactive position or moving it to the action position via the moving rod 28 is performed in the same direction and at the same speed as the sliding direction of the carriage 8. It circulates.

Further, in relation to the sorting cam mechanism 10 provided on the carriage 8, especially the lowering cam 12, a handle plate 17 with a hook-shaped projection 17a capable of locking the butt 4a of the knitting needle 4 when it is pressed down is provided. is moved to the working position by the action of the lateral movement cam AC, locks the reduction knitting needle 4 to the hook-shaped protrusion 17a, and holds the temporary low butt needle only while receiving the action of the cam AC. The relationship is such that it is released when it crosses the separation cam 13. Therefore, the knitting carriage 8 for accurately producing these timings is configured such that it can interlock with the endless belt 15 only when the connecting pin 16 is fitted into the connecting hole 15b of the endless belt 15, and Even when the connecting pin 16 is fitted into any of the connecting holes 15b, the required timing is ensured.

Depending on whether or not light is received, a pulse signal synchronized with the knitting needle position caused by the sliding movement of the carriage 8 is outputted at a period of the pitch of the slit 30a.
Further, a second photoelectric detection element 32 is supported on the support frame 22 in front of the first photoelectric detection element 31, and a light emitting element 32a arranged to sandwich the recess 30b of the code disk 30 from both sides. Depending on whether or not the light receiving element 32b receives the projected light, a signal whose phase is advanced or delayed relative to the pulse signal is outputted depending on the rotational direction of the code disk 30 corresponding to the sliding direction of the carriage 8. It's becoming like that.

A right reference magnetic resistance element 33 is attached to the rear of the knitting needle 4 on the right side, at a position further shifted outward by a half pitch to the right than knitting needle 4 on the right side, and also shifted further outward to the left by a half pitch from the knitting needle 4 on the left side A left reference magnetic resistance element 34 is attached at the position shown in FIG.
The installation location of the right reference magnetic resistance element 33 is on a line shifted 3.5 pitches to the left from the rotation axis of the right pulley 14, and the left reference magnetic resistance element 34 is located on a line shifted from the rotation axis of the left pulley 14 by 3.5 pitches. It is located on a line that is half a pitch off to the right from the heart. At the rear of the knitting carriage 8, a magnet body 35 is attached to the carriage center line C so that it can closely correspond to the magnetic resistance elements 33 and 34 for the right reference and left reference when installed on the needle bed 3.
When placed close to each magnetoresistive element 33, 34, an external magnetic field is applied to each element 33, 34.

Next, the operation of the knitting machine configured as above will be explained. First, first, the magnetic disk device 1
34 will be explained with reference to FIGS. 9 to 12. The flowchart shown in Figures 9 to 12 is
CPU according to the program built in ROM131
125 and the CPU 101 of the knitting machine main body 1.

This magnetic disk device 134 is configured to have a full erase mode, a read mode, a write mode, and a partial erase mode set based on the input of a command number using the numerical input switch 45 shown in FIG. "550" sets the full erase mode, "551" sets the read mode, "552" sets the write mode, and "553" sets the partial erase mode.

Now, when the start lamp 39 is lit, the on operation of the clear switch 53 shown in FIG. 6 is awaited in step S201 of FIG. The command number is determined in steps S203 to S206, and if the command number is "550", the process advances to step S207 and waits for the step switch 54 to be turned on, and when the step switch 54 is turned on, the step In S208, the display and lamp of the key switch operating device 36 of the knitting machine main body 1 go out, and the magnetic disk device 134 operates to erase all data on the magnetic disk, thereby erasing all data on the magnetic disk. When the deletion is completed, the determination result in step S209 becomes YES, and the process proceeds to step S210, where the display and lamp on the key switch operating device 36 return to the state when the start lamp 39 is lit.
When the command number "551" is input, the step switch 54 is turned on in step S211 shown in FIG.
searches the data on the magnetic disk and when it becomes readable, the start lamp 39 and pattern number lamp 40 are lit in step S213 to prompt input of the track number stored on the magnetic disk, and in step S214 the data is input. The input of the number by the switch 45 is awaited. Then, when the step switch 54 is turned on in step S215 after the number input is completed, the pattern information of the track number inputted in step S216 is transferred to the knitting machine main body 1.
Transferred to RAM 113. When the transfer is completed, the determination result in step S217 becomes YES, and the process proceeds to step S218, where the key switch operating device 3 is turned on as in step S210.
6. The display and lamp above return to their original state.

When the command number "552" is input, the step switch 54 is turned on at step S221 in FIG. S2
At step S23, the start lamp 30 and pattern number lamp 40 are turned on, and the process proceeds to step S233.
At step S22, the track number to be written is displayed on the first display window 57.
At step 4, turning on of the step switch 54 is awaited.

By turning on the switch 54, step S2
At step 25, the displayed track number and its pattern information are written on the track detected at step S222, and upon completion of writing, the process goes to step S226 and returns to the original state at step S227.

Further, if the command number "553" is input, the start lamp 39 and the pattern number 40 are lit in step S232 after passing through step S231 to prompt input of the track number, and the second display window 58 shows "0" is displayed. This "0" indicates partial erase mode. Then, in step S223, input the track number you want to erase, and then press step S223.
When the step switch 54 is turned on in step S234, the pattern data of the designated track number on the magnetic disk is retrieved in step S235, and is erased in step S236. When erasing is completed, the step switch 54 is activated in step S238 via step S237.
The ON operation is awaited, and when the ON operation is performed, the original state is returned to in step S239. If you wish to continue erasing the data of another track number, enter that track number after step S237 and the program will return to step S234.

Next, a method of organizing the creative pattern will be explained. First of all, we will explain how to input creative patterns in the 13th section.
This will be explained based on the diagram.

When the power is turned on by the power switch (not shown) of the knitting machine main body 1. In step S101, the input switch 69 is waited for to be turned on, and as a result of the on operation, the pattern number lamp 40 is lit in step S102, and the number that will be the pattern number of the pattern to be input from now on is displayed in the first display window 57. and step S10
At step 3, turning on of the step switch 54 is awaited. When the step switch 54 is turned on, the left needle position display lamp 43 is turned on in step S104, prompting the operator to input the number of stitches of the created pattern.

Then, when the required number of stitches is input in step S106, it is displayed on the first display window 57 in step S107, and
The number is written to register 119 and step S
At step 108, turning on of the step switch 54 is awaited.

When the step switch 54 is turned on, in the next step S109, the right hand position display lamp 44 is lit in order to input the number of steps, and the first display window 57 can be input with the pattern of the inputted stitch number. The value of the maximum number of stages is displayed, and in step S110, turning on of the clear switch 53 is awaited. clear switch 5
3 is turned on, the step number display is turned off in step S111, and step S112 waits for a step number input by numerical input.
Then, when the number of stages is input, step S11
At step S3, the data is displayed on the first display window 57, and the data is written to the register 119, and the turning-on operation of the step switch 54 is awaited at step S114. Note that when this step switch 54 and the clear switch 53 are turned on, the previous first and second display windows 5
7, 58 and lamps are turned off except for those necessary.

When the step switch 54 is turned on in step S114, a number (for example, "1") indicating the eye to which pattern data can be input is displayed in the first display window 57 in step S115. This step S115 is a step in which creative pattern data can be input, so it will be explained. The creation of this creative pattern data is performed using the first and second creative switches 66 and 67, and when changing stitches to other colored threads, etc., the first creative switch 66 is used. To do this, the second creative switch 67 is turned on.

That is, since the first display window 57 displays an eye that allows data to be input, if the first or second creation switch 66, 67 is turned on accordingly, the corresponding data will be transferred to the register 11.
9 and displayed on the creation confirmation display section 68 as shown in FIG. Along with being added,
The display section 68 also sequentially displays increasing numbers. When the switches 66 and 67 are turned on after all the display sections 68 display, the display operation returns to the initial display operation of the display section 68, and display starts again from here.

In this way, when the input of the set number of stitches for each row is completed, the buzzer will sound briefly each time.
When the input of the last eye in the final stage is completed and the creation of pattern data is completed, a buzzer sounds for a long time to notify the operator. When the input of the creative pattern is completed and the step switch 69 is pressed in step S116, the program exits from the pattern creation mode. Note that even if the input switch 69 is operated during the creation of pattern data, the pattern creation mode can be exited.

In the case of creating this creative pattern, in this knitting machine, raised parts 87 and 88 are formed on the upper surfaces of the creative switches 66 and 67, and other switches are placed on the same plane lower than the raised parts 87 and 88. Since the switch is placed in the middle of the screen, there is no risk of erroneous operation, and it is possible to operate the switch by groping while looking at a pattern collection or the like.

The creative pattern created as described above can be written to the magnetic disk of the magnetic disk device 134 by the program shown in FIG. It can be transferred to the RAM 113 of the computer and stored in the creative pattern area 118 thereof.

Therefore, an example of knitting that is performed based on the creative pattern data after it is transferred to the RAM will be described below with reference to FIGS. 15 to 17.

Now, when the power switch (not shown) is turned on, since the RAM 113 is backed up by another power source, it returns to the state before the power switch (not shown) was turned off in step S1, and the display windows 57, 58, The lamps etc. display their states before being turned off, and in step S2, it is determined whether one of the pattern selection switches has been turned on, and in the scanning through steps S1 and S2, whether one of the pattern selection switches 37 or 38 has been turned on is determined. I'll be waiting. When one of the pattern selection switches 37 or 38 is turned on, steps S3 and S
Pattern selection switch S that was turned on after progressing to step 4
When the lamp 37 or 38 is turned on, the step switch 54 is awaited for turning on, and a scan is executed from step S2 to step S4 until the step switch 54 is turned on.

When the step switch 54 is turned on, the process proceeds to step S5 and step S6, where the pattern number lamp 40 lights up to prompt input of the pattern number of the creative pattern, etc., and when the clear switch 53 is turned on, After waiting, the second display window 58 is turned off. By operating the clear switch 53, the display in the first display window 57 is also turned off in step S7, and only the pattern number lamp 40 continues to be lit. In this way, when the step switch 54 and the clear switch 53 are turned on, unnecessary items that have been displayed up to that point are turned off. Next, in step S8, input of a pattern number by the numerical input switch 45 is awaited, and when a number is input, it is displayed on the first display window 57 and written in the register 119 in step S9. ,
In step S10, it is determined whether the step switch 54 is turned on, and if NO, the process proceeds to step S10.
Returning to step 8, the desired pattern number can be input during the scan through steps S8 to S11.

When the input of the pattern number is completed and the step switch 54 is turned on, the process proceeds to step S11, where it is determined whether the input pattern number is the number of a unit pattern built into the ROM 120. If the pattern is a built-in pattern, the pattern in the ROM 120 is read out in step S12 and stored in the register 11 of the RAM 113.
9, and if it is not a built-in pattern, that is, the pattern data of the input unit pattern number is
If the pattern data is stored in the RAM 113, the pattern data is stored in the register 119 in step S13.
will be forwarded to.

A desired unit pattern can be selected in the manner described above.

In the next step S14, it is determined whether or not the continuous pattern mode is set. Therefore, the operation when the continuous pattern mode is selected by turning on the continuous pattern selection switch 37 in step S2 will be explained below with reference to FIGS. 9 and 14. That is, in the case of continuous pattern mode in which the determination result in step S14 is YES, the process advances to step S15 in FIG. An operation is performed to divide the large number by 2, and the value is stored in register 119.
and is displayed on the first display window 57. Therefore, the left needle position display lamp 43 and pattern position lamp 42 indicate to the operator that the display on the first display window 57 indicates the left end position L of the unit pattern on the center C of the knitting machine. be done.

In the next step S16 and step S17, the step switch 54 or the clear switch 5
3 is awaited, and in this case, the operator turns on the step switch 54. Therefore, the program advances to step S18, where the start lamp 39 is turned on and the knitting data such as the pattern number and pattern position stored in the register 119 is transferred to the corresponding RAM 11.
3, the knitting data for the continuous pattern shown in FIG. 14 is set, and the row number and memo number of the beginning of the pattern are displayed in the first and second display windows 57 and 58, respectively. be done.

Thereafter, the carriage 8 is moved by the worker, and each time it reaches the needle selection position of each knitting needle, the code disk 3
Based on the signal from 0, the CPU 101
The knitting pattern information is read from 3 to control the operation of the needle selection position 29, and the knitting needles are placed at the front needle selection or rear needle selection position depending on whether the electromagnet is activated or not, and knitting including the pattern is executed. Each time the composition is completed, the display in the first display window 57 is added one by one.
As described above, the selected unit pattern is automatically knitted and realized in the center of the knitting machine, and the same pattern is continuously realized on the left and right sides of the selected unit pattern. Note that the display on the second display window 58 shows memo contents such as the code of the colored thread to be used.

Next, a method of erasing the creative pattern stored in the RAM 113 will be explained based on FIG. After the power is turned on, the input switch 69 is turned on in step S31, and then the input switch 69 is turned on.
In step S33, the pattern number lamp 40 is lit, and the clear switch 53 is awaited for turning on. When the clear switch 53 is turned on, an input of the pattern number to be erased is waited for in step S34, and upon input, that number is displayed on the second display window 57 in step S35, and the erase switch 75 is turned on in step S36. The pattern data of the pattern number designated in step S34 is erased in step S37 by the ON operation.
