Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a forming instruction device for a knitting machine that reads and displays stored values as the knitting stage progresses from an electronic 8-device that stores the number of stitches for each knitting according to the knitting type. It is.

As mentioned above, the purpose of the present invention is to visually display the information on the proof stitches according to the knitting type by numerical display, so as to make it easy to judge the number of stitches corresponding to each knitting stage and the increase or decrease thereof. , and the display of the number of months of increase/decrease in the present invention uses a unique configuration that detects the actual number of stitches in each row with respect to the stored value and displays the difference between them.
Even if an increase/decrease operation with a different display theory is made by mistake, this error will not be inherited from next time onwards.

Examples will be described below with reference to the figures.

First, we will start by explaining the requirements of the mechanical parts in Figures 1 to 6.

In the 0-OR circuit 104 that supplies power to 31a and 133a, each time the lowering cam 5 newly acts on any of the pattern switches GS1 to GS8, the output GN acts for the time set by the single circle M1 to M8. .

OR circuit 101 has one or more lowering cams 5 and handle plate switch G
While acting on Si~8, it is the inverting circuit 10
2, it becomes inactive and does not reset the up counter 103.

When all of the pattern switches GS1 to GS8 are not in effect, the OR circuit 101 is inactive, the inverting circuit 102 is in effect, the up counter 103 is reset, the decoder 134 is operated with an O output, and 1 to 3 outputs are inactive and act on the inverting circuit 118.

Here, when the output GN of the OR circuit 104 acts, the OR circuit 101 acts, the inversion circuit 102 becomes inactive, the up counter 103 is released from reset, the AND circuit 109 acts, and the up counter 103 counts up. However, the first output TOP l acts on the decoder 134, and the 0 and 2.3 outputs have no effect.

Next, when the output GN acts, the up counter 103 further counts up and the decoder 134 outputs the second output TOP.
2 is active, 0.1 (TOPI), and 3 output is inactive.

Next, when the output GN acts, the up counter 103 further performs count amplification, the third output acts on the decoder 134, o, ■ (TOPl), 2 (TOP2) become inactive, and the inverting circuit 118 also becomes inactive. Therefore, the AND circuit 109 also becomes inactive.

Therefore, even if the output GN is applied next time, the up counter 103 will not change to run 1, so the third output will remain active until the reset input is applied.

The encoder 105 converts each of the eight input terminals into a binary 3-bit output, and is a single-digit signal M1 to M8.
For each input of pattern plate operation signals 01 to G8 via respectively,
For input 01, output (0, 0, 0], for G2, [0, 0, 1], and sequentially for human input G8, output [, i
, 1].

The 3-hibt output of the encoder 105 is connected to the lower digits of the 5-bit output of the up-down counter 108, and the downstream operation of the knitting needle can be specified using a total of 8 bits.

This will be explained later, but first the decoder 134
When the output TOP1 occurs, each output of the encoder 105 is stored in the up counter 114.

Next, when the output TOP2 occurs, the up counter 114 is counted up and each output of the encoder 105 is stored in the lunch 116.

Comparison circuit 120 includes up counter 114 and latch 116
The output acts if the outputs of are equal.

The FF115 is reset when the output TOPi occurs in the decoder 134, and the output R1 is applied, and then the output TOP2 is applied.
If the comparator circuit 120 is operating when
The AND circuit 11γ acts, F and F 115 are set, and the output Le acts.

That is, when the output TOP2 is generated by a pattern switch number that is one number larger than the pattern switch number generated by the output TOP1 (G51 in the case of GS8), the output Le acts.

This indicates that the lowering cam 5 attached to the carriage 4 is running to the left.

Conversely, when the downstream cam 5 is running to the right, the output Ri remains applied.

The up/down counter 108 stores the search switch KSI~5 when the output TOPI of the encoder 134 occurs.

When the single mark M1 acts while the output Le is being generated, the AND circuit 106 acts and the up/down counter 108 counts up.

As can be seen from FIG. 4, in the case of left-hand travel, when the lowering cam 5 acts on the pattern plate G1, the block number increases by 1, so the block number protected by the up-down counter 108 is increased by 1. .

When the single signal M8 acts while the output Ri is being generated, the AND circuit 10γ acts and the up/down counter 108 counts down.

As can be seen from FIG. 4, when the lowering cam 5 acts on the pattern plate G8 in the case of right-hand travel, the block number decreases by 1, so the block number stored in the amplifier down count 108 is decreased by 1.

That is, the up/down counter 108 outputs a binary number corresponding to the block number to which the knitting needle 2 newly rolled down by the rolling down cam 5 belongs.

As described above, the output of the up/down counter 108 and the output of the encoder 105 are connected to the subtraction circuit 119, and the block number of the newly pressed knitting needle 2 and its pattern number are inputted in binary numbers. .

The block number of the reference knitting needle 2 and its pattern number are input in binary to the B input of the subtraction circuit 119.
19 [A-B] Ratio output Subtracts the binary number of input B from the binary number of input A and outputs the result.

(One bit out of 8 bits means a sign.

) Then, when the output TOP1 of the decoder 134 occurs, it is stored in the [A-B] ratio output latches 120 and 121.

Next, when the output GN occurs while the output Le is occurring, the latch 120 newly stores the corresponding [A-B) output.

When the output GN occurs while the output Ri is occurring, the latch 121 re-memorizes the new [A-B output.

That is, in the knitting process of one stage, the position numbers of the knitting needles 2 that are first pressed down are also stored as launches 120 and 121.

In the case of left-hand travel, the position number of the knitting needle 2 is stored in the latch 120 each time the knitting needle 2 is newly pressed down, and in the right-hand travel, the position number of the knitting needle 2 is stored in the latch 121 each time the knitting needle 2 is newly pressed down. It is something to remember again.

When the switch 305 is closed, the up/down counter 309 counts and amps when the OR circuit 101 is activated, that is, every time a one-stage formation is formed and every time the switch 306 is activated, and when the switch 305 is opened. If there is, the count is increased only when the switch 306 is activated.

Further, the up/down counter 309 counts down each time the switch 301 is activated.

The ROM 315 has a solid line 354 on the right side of the pattern 352 for the ROM stage number at each address in the ROM stage number 351 column drawn in the small pattern chart 350 shown in FIG.
7 bits indicate the number of stitches from the center line 353 of the pattern, and the remaining 1 bit indicates the number of stitches from the center line 353 of the pattern.
This 1-bit code is stored as ○ if it is to the right of 3, and ■ if it is to the left.

Similarly, the ROM 316 has a small pattern diagram 3 shown in FIG.
At each address in the ROM stage number 351 column drawn in 50, a solid line 355 is drawn to the left of the pattern 352 in each stage.
The number of stitches from the center line 353 of the pattern is stored in 7 bits, and if the solid line 355 on the left is to the right of the center line 353 of the pattern, it is ○, if it is to the left, it is ■, and the code is stored in the remaining 1 bit. There is.

The switching circuit 317 is composed of a gate circuit, a data selector circuit, or the like.

The gate circuit 301 is a gate circuit in which an AND circuit is provided for each manual bit, and when the switch 302a is closed, the write input is output as is, and when the switch 302a is open,
All outputs are inactive and become binary code signals meaning zero.

The subtracting circuits 119, 303, and 304 are composed of full adders or the like, and one bit of each has a sign.

(When it is working, it means ○, and when it is not working, it means ■.

) converters 122, 123, and 310 are known binary, to, and BCD converter circuits, converting binary code into 1
Convert to decimal BCf) code.

Decoder drivers 124-i27, 31L-314 are known BCD-7 segment decoder driver circuits.

The numeric display devices D1 to D8 use LED display elements, etc., and are provided at positions easily visible to the user, as shown in FIG.

In the electric circuit shown in FIG. 1, correction of timing caused by delay between elements or delicate timing is omitted.

Note that the small pattern chart 350 in FIG. 9 is used in conjunction with the above-described component device of the present invention, and each pattern to be organized corresponds to the data stored in the ROM 315, 316, and, so to speak, Diagram 350
serves as a manual for each ROM.

The operation of the device of the present invention will be explained below.

First, pattern 35 for the front body according to pattern chart 350.
2, the number of stages is set from 20. By displaying the number of stages D5 to D8 as 20, the read address of the ROMs 315 and 316 is set to the 20th stage.

To do this, manually operate switches 306 and 301 to adjust the counting status of up/down counter 309. For example, if 15 is displayed on stage number displays D5 to D8, operate switch 306 five times. 20
is displayed.

If 23 is displayed, switch 30γ is activated three times to display 20.

On the other hand, switch 302a is set to open (switch 302b is as shown in FIG. 7), switch 305 is also set to open, and switch 318a is set to GAi (switch 302b is as shown in FIG. 7).
18b and 318c as shown in FIG. 7).

For example, if the number of stitches when the number of ROM stages is 20 is 80 on the left and 080 on the right, the ROM 315 is affected by the address input of 20 of the up/down counter 309 and outputs 080.

1 bit means ○, and the remaining 7 bits mean 80.

Since switch 318a is set to GAi, R
O~R1 means 080 (switch 318b is the first
(The sign does not change because it is in the state shown in the figure.)

It becomes the Br input of the subtraction circuit 303.

Since the switch 302a is open, this means that the Ar input is zero.

The output of the subtraction circuit 303 [Ar-B r ] becomes 80, and the inversion circuit 129 acts, and the switch 30
2b is in the state shown in FIG. 1, the right lamp 133b is lit.

On the other hand, the number display devices D4 and D3 display 80.

The ROM 316 is affected by the address input 20 of the up/down counter 309 and outputs 80.

1 bit means ■, and the remaining 7 bits mean 80.

Switch 318a is set to GAI, so LO
~L1 means [exist]80.

(Since the switch 318c is in the state shown in FIG. 1, the sign does not change.) This becomes the A7 power of the subtraction circuit 304. Since the switch 302a is open, the 86 power means zero.

The subtraction circuit 304 [A! ! -Bll ] output becomes ■80, the inverting circuit 128 acts, and the switch 302
Since b is in the state shown in FIG. 1, the left lamp 131b is lit.

On the other hand, the number display device D2 displays 80 on DI.

The user knits 80 stitches to the right and 80 stitches to the left from the reference needle of the knitting machine, and after knitting the final thread, press switch 3.
Set 05 to close.

To make it easier to explain the action, ROM315.316
is stored as shown in Table 1 below.

(Binary numbers are expressed in decimal numbers.) When the carriage 4 is moved from left to right, the up counter 103 is reset and the decoder 134 outputs 0 until the left end knitting needle is pressed down.

Then, when the left end knitting needle is pressed down, the OR circuit 101 is activated, the up/down counter 309 counts up by one and becomes 21, and 21 is displayed on the number display devices D5 to D8.

On the other hand, the TOP1 output is activated, and the subtraction circuit 119 subtracts the binary bit code B input of the reference knitting needle from the binary bit code A input of the leftmost knitting needle. to be memorized.

When the next rightward knitting needle acts, TOP2 output, GN output, Ri high output is generated, and CA-Br output ■79
asks the latch 121.

The latch 120 remains at ■80. As the lowering cam 5 moves to the right, the latch 121 moves as shown in ■78. [Yes] 77, ■76
...and the memory changes.

Then, when the reference knitting needle is pressed down, the latch 121 stores O.

When the lowering cam 5 further moves to the right, the latch 120 remains at ■80 and the latch 121 becomes 01, 02, 03, etc.
...and the memory changes.

Then, when the rightmost knitting needle is pressed down, the latch 121 becomes 0.
80 is stored.

When the lowering cam 5 stops pressing down the knitting needles, the OR circuit 1
01 becomes inactive, and the one-stage formation ends.

On the other hand, as shown in Table 2, the ROM 315 outputs e81 in response to the address input 21, and connects it to the Br input of the subtraction circuit 303. D4 and B3 are displayed as 81.

Similarly, the ■81 output of ROM316 is the left lamp 131.
b lights up, and the number display device D2 and DI display 81.

Here, when the user closes the switch 302a (switch 302b becomes the opposite of that in FIG. 1), the Ar input of the subtraction circuit 303 becomes ・80, and the Br input;
remains 1 and CAr-Br,] The output becomes 1 and the lamp 133a and the numerical display device D4. D3 is displayed as 1.

87 manpower of the subtracting circuit 304 becomes *80, A7 manpower remains at *81 (A7-87), the output becomes *1, and ■lamp 131a and numeric display device D2, DI displays 1.

The user looks at the display and increases the number of stitches on the right side by one stitch, and also increases the number of stitches on the left side by one stitch.

And this time, when carriage 4 is run from right to left,
Until the right end knitting needle is pressed down, the up counter 103 is reset and the O output is applied to the decoder 134.

Then, when the right end knitting needle is pressed down, the OR circuit 101 is activated, the up/down counter 309 counts by one and becomes 22, and 22 is displayed on the number display devices D5 to D8.

On the other hand, the TOP1 output acts, and the subtraction circuit 119 subtracts the binary bit code B input of the reference knitting needle from the binary bit code 8 input of the rightmost knitting needle, and the binary bit code of [A-B] becomes 081, and the latch 120, 121.

Then, when the next knitting needle on the left acts, TOP2 output, GN output, and Le output are generated, and [A, -f3] output 08

The ROM 315 outputs 058 as shown in the table above in response to the address input of 182, which becomes the Br input of the subtraction circuit 303. On the other hand, the Ar input is 058, so the [Ar-Br] output becomes zero, and the numeric display devices D4 and B3 Display O.

The ROM 316 outputs 012 in response to the address input of 182, and the output of A1 of the subtraction circuit 304 becomes 07. On the other hand, the output of 81 is 07, so the [A1-B1] output becomes 05, lighting up the ○ lamp 130a, and turning on the numeric display device D2. DI is displayed as 5.

The user looks at the display and leaves the right edge as it is, but reduces the left edge by 5 (by doing so).

In this way, the shoulders are knitted.

Next, as shown in FIG. 9, when knitting the left shoulder section drawn by the broken line in the figure, the switch 302a is opened and the switch 318a is set to the Ga2 side.

(Switches 318b and 318c are in the opposite state as in FIG. 1.

displays 58.

ROM316 similarly returns 0 for address input of 181.
Since the switch 318a is set to Ga4, the output is RO~1.

RO is inverted by the inverting circuit 319, and RO~1 becomes 7, which becomes the Sr input of the subtraction circuit 303.

On the other hand, the Ar input is zero because the switch 302a is open [Ar-Br1 output is 07, the left lamp 132b is lit, and the numeric display devices D4 and D3 are 7
Display.

The user sets the right end of the narrow cloth to the 7th stitch to the left of the standard knitting needle, and the left end of the narrow cloth to the 58th stitch to the left of the standard knitting needle.

When one stage is formed, the latch 120
is stored as ■58, and ■7 is stored in the latch 121.

Then, switch 302a is set to close.

The count of the up/down counter 309 is 182, and the number display devices D8 to D5 display 182.

The ROM 315 outputs 058 for the address of 182, and as described above, LO to L1 becomes 58 and becomes the Al input of the subtraction circuit 304.

Then, the BA' input becomes [F]58, the [AA-BA] output becomes zero, and the numerical display device D2°Dl displays O.

The ROM 316 outputs 012 in response to the address input of 182, and as described above, RO to R7 becomes 12 and becomes the Br input of the subtraction circuit 303.

And since Ar input is ■7, (Ar-Br) output is 05
The adjacent ○ lamp 132a lights up, and the numeric display device D4
, D3 is displayed as 5.

The user looks at the display and subtracts 5 stitches from the right edge (by cutting, etc.) and leaves the left edge as is.

In this way, the left shoulder part, which is symmetrical to the right shoulder part, is molded.

In this way, the ROM memory value of the part drawn by each ship symmetrically from the center line of each pattern is to store only the stitch data of one pattern in that part, and the stitch data of the opposite side. In the same way as in the actual knitting operation, the readout address is returned to the knitting stage where the horizontal separation started, and the data for the symmetrical pattern is displayed by reversing the ROM readout data left and right. Below, in the case of knitting the back body on the pattern chart 350 of FIG. 9, the same operation as above is performed when knitting the shoulder part at the 425th row of the ROM read address as shown in the figure.

In this way, as the knitting progresses, the stitch numbers are sequentially drawn in the pattern diagram 350 and the number of stitches D1 to D4 corresponding to the address operation, using the number of rows written in the column 351 of the number of rows of the ROM as indicators. Each garment part can be molded.

In addition, according to the present invention, the number of stitches is fixed for each pattern, so the finished size of the molded product can be adjusted by changing the thickness of the thread used, adjusting the stitch dial, etc. Use the following methods.

As shown in the diagram above, the stitch display device of the present invention can provide a direct index of increase/decrease stitches for molding work by indicating the difference between the previous and next stages for each stage in the display method. It is easy for people to understand.

In addition, when the pattern line changes greatly from side to side or when stitches have a large change, such as when the stitches are symmetrical and are divided into left and right at the center of 9, the display changes immediately to the number of stitches from the reference needle by operating a switch. This allows accurate reading to be ensured at all times when compared with the pattern chart used in combination.

Furthermore, in the present invention, when detecting the number of difference between each stage, the actual knitting needle signal is used as the numerical signal for the previous stage.
Errors caused by erroneous operations are not accumulated or remain behind.
