Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic control device for a knitting machine, and particularly includes a storage means for storing information on a desired pattern to be knitted, and stores information stored in the storage means.
The present invention relates to an improvement in an electronic control device for a hand knitting machine that displays information on the knitting machine main body or an attached display unit each time a carriage passes a predetermined position on the knitting machine.

Conventionally, when attempting to knit clothing or the like using a hand knitting machine, measurements and gauge values are determined before actually going to the knitting machine and starting work.
It is necessary to calculate the number of stitches and rows based on these measurements, and also to draw the external dimensions of the item to be knitted. Next, when actually working on the knitting machine, observe the intersection position of the outline of the above-mentioned drawing and the stitch scale of the knitting machine body, and then make the garment one by one while increasing and decreasing stitches. etc. are knitted together.

In this way, knitted fabrics made using conventional hand-knitting machines,
For many general users, operations such as calculating the number of stitches and rows of stitches, and observing the intersecting position of the outline of the drawing and the stitch scale when actually knitting the item to be knitted are extremely troublesome. I had to.

Therefore, the present applicant first solved the above-mentioned drawbacks of the conventional method, eliminating the need for drafting and calculating the number of stitches and rows, and providing instructions on what to knit and the gauge of the yarn used for the knitted fabric. By inputting only the value and desired measurement value, instructions for increasing and decreasing stitches and information on the number of rows related to the knitting pattern are sequentially notified, making it possible to knit with extremely simple operations. A useful knitting machine was proposed. Simply put, this proposed knitting machine is:
Calculation formulas for the number of stitches, rows, etc. for multiple types of standard patterns and measurements for the knitting machine, such as for knitting and sweaters, are stored in advance within the knitting machine main body or in an attached storage means, and the operator can use the pattern instruction means to indicates the desired standard pattern of knitting,
Furthermore, by inputting the measured values and gauge values, calculations of the number of stitches, number of rows, etc., as well as expansion or reduction of the number of stitches, number of rows, etc., are automatically performed based on the measured values, and these calculation results are sent to the knitting machine itself. In addition to informing the operator by displaying it on a display section provided or attached, the display section also instructs the operator about the number of increasing stitches, the number of subtracting stitches, and the number of rows each time the operator knits one row of the desired pattern. This is a knitting machine made with

Therefore, an object of the present invention is to further improve the novel knitting machine proposed above and to provide a simpler electronic control device for the knitting machine.

An electronic control device for a knitting machine according to the present invention that achieves the above object includes a storage means capable of dividing and storing information on a pattern to be knitted into a plurality of parts corresponding to an actual knitting operation; end detection means for detecting the end of the knitting operation of each part among the parts; an operation completed signal input means; Displaying content instructing a knitting operation, and responding to an input signal from the operated signal input means that is operated in response to the display of content instructing the knitting operation,
When the next knitting operation is a flechage, the end of a knitting operation, or a droop stitch, selectively displays the contents instructing the flechage, the end, or the droop stitch, respectively, and also displays information regarding the number of stitches required for the knitting operation. It is characterized by including an editing operation display means for displaying.

The above objects and other objects and features of the present invention will become more apparent from the detailed description given with reference to the drawings.

FIG. 1 is a diagram showing an example of the pattern of the front body, and FIG. 2 is a block diagram showing the main parts of an embodiment of the present invention. In the configuration, the input means 1 includes:
For example, this is for inputting the pattern, gauge value, size, part, left and right, etc. to be knitted, such as a twill or sweater, the details of which are shown in FIG. The arithmetic control means 2 selects a combination of standard patterns stored in the storage means 3 based on the instruction input information input from the input means 1. Then, based on the selected pattern and the input gauge value and size, for example, the main points M1, M1, and M1 of the front body pattern shown in FIG.
The number of stitches and number of rows of M2,...M5 are calculated. The information calculated by this calculation control means 2 is
It is stored at a predetermined position in the storage means 3. Therefore, the storage means 3 has an area for storing information on at least some standard patterns and the calculation results from the calculation control means 2. The display means 4 displays information such as the number of stitches, widening stitches, subtracting stitches, etc., based on information from the arithmetic control means 2. The row number sensor 5 generates one pulse signal α each time the carriage passes a predetermined position (for example, the center) of the knitting machine, and sends a signal indicating the completion of one row of knitting operation to the calculation control means 2. Enter. Based on the pulse signal α from the row number sensor 5, the calculation control means 2 causes the display means 4 to display how many rows of the desired pattern have been knitted. Further, in the arithmetic control means 2, the stage number information formed by the pulse signal α is given to the stage number comparison means 6. The number of rows comparison means 6 receives the increasing and decreasing stitch information stored in a predetermined area of the storage means 3, detects the coincidence of this number of rows information and the information from the storage means 3, and determines whether the next knitting operation will be increased or decreased. Detects whether it is an eye or a reduced eye. That is, if this stage number information matches the information in the storage means 3, the next operation is displayed on the display means 4 via the arithmetic control means 2, and whether the next operation is an increase or a decrease is displayed. The number of stitches is displayed, and the next instruction is given to the operator.

One feature of this invention is the operated key 101 provided on the input means 1. Operated key 101
This key 101 is pressed after a part of the pattern of operation of a specific part that has been stored in multiple parts is completed, and is provided to display the next pattern of the specific part by operating this key 101.

Here, the operation of the key input means 1 will be briefly explained with reference to FIG. When specifying the item to be knitted, use the numeric keypad 13 to input the address code of the standard pattern of a plurality of works stored in a predetermined area of the storage means 3 in advance.
Thereafter, the "work" key 102 is pressed. Also,
When inputting a gauge value, the gauge key 11 and numeric keypad 13 are used. That is, when inputting a gauge number, the numerical value is input using the numeric keypad 13, and then the "gauge number" key 131 is pressed. Further, when inputting a gauge stage, first input the numerical value using the numeric keypad 13, and then press the "gauge stage" key 132.

Furthermore, if the user wishes to change the size of the knitted fabric, the operator presses the "L" key 103 or the "S" key 104, which indicates the size of the knitted fabric. If neither of these two keys 103 and 104 is pressed, an M size knitted fabric will be automatically created. Then, which part of the work specified by the "work" key 102 is knitted is determined by the "front body" key 121, "back body" key 122, "left" key 123, "right" key 124, etc. of the partial keys 12. Specified by. Note that if you want to know the section where the number of stitches does not change, you can press the "X" key 106 to search for that section and display it on a display means or the like. The "operated" key 101 is also used to instruct the start of a knitting operation. Here, the functions and operations of the key input means 1 described above are merely examples, and it goes without saying that the number of these keys can be increased or decreased as appropriate depending on the knitting machine.

Next, an outline of the operation or operation will be explained with reference to FIGS. 1 and 2. First, the operator specifies the "work" depending on what he or she is trying to knit.
In addition, the gauge value, size, portion, etc. are specified using the input means 1. The instruction input information is input to the arithmetic control means 2, which selects a combination of standard patterns stored in the storage means 3, and the arithmetic and control means selects the main point M
The number of stitches and the number of rows of 1 to M5 are calculated and stored in the storage means 3. After setting the knitting machine or attached equipment to such a state, the actual knitting operation begins.

In the editing operation, the operator first selects the display means 4.
Move the knitting needles to the knitting position for the predetermined number of stitches required to knit the desired pattern displayed on the screen to perform set-up, and then create the desired pattern by operating the carriage of the knitting machine main body. .

When the carriage is operated, the row number sensor 5 generates a pulse signal α every time the carriage passes a predetermined position on the knitting machine. In response, the arithmetic control means 2 causes the display means 4 to display how many rows of the pattern of the desired size have been knitted. Further, the operation is performed based on the number of rows information formed based on the signal α indicating the completion of this one row knitting operation and the information on increasing and decreasing stitches stored in a predetermined area of the storage means 3. The operator causes the display means 4 to display information such as the number of stitches of the next row, widening stitches, subtracting stitches, etc. Following this instruction, the operator moves the knitting needle to the knitting position for the specified number of stitches in the case of widening stitches, and moves the stitches from the knitting needle to the knitting position for the specified number of stitches in the case of shortening stitches. Remove. The knitting operation is continued by repeating such displays or instructions and operations.

When the main part M3 shown in FIG. 1 is knitted, part B is treated as a "turnback" and knitting is stopped, and part A is knitted first. When the main part M5 of part A is knitted, the number of steps of the main part M5 stored in the storage means 3 matches the current number of steps formed based on the pulse signal α in the arithmetic and control means 2. It is detected by the stage number comparing means 6.
Then, based on the coincidence detection signal from the stage number comparing means 6, the arithmetic control means 2 causes the display means 4 to display that part A in FIG. 1 has been completed and a second stitch is required. That is, the stage number comparison means 6
This constitutes an end detection means for detecting the end of the knitting operation of each section.

Here, the knitting is done in the middle of the knitting process.
This is to prevent the inconvenience that the threads at the beginning and end of the knitting work come undone or the stitches become uneven, resulting in unevenness and density at the beginning and end of knitting.
This is the part where three extra rows are knitted and will be removed later. In other words, it is a guard that prevents unraveling of the threads and unevenness of the stitches from actually reaching the work. In addition, for example, waste knitting is performed in advance at the joints that connect the front and back sections, and the aim is to prevent the inconvenience of distorting the joints by connecting the knits that have been used unevenly and coarsely and densely. have

The number of rows of this stitching varies depending on the shape of the work, the type of thread, the level of skill of the knitter, etc. In some cases, it is not necessary to perform the stitching at all; It is influenced by human judgment.

The operator looks at this display of "last stitch" and performs the last stitch for an arbitrary number of rows. In this case, the pulse signal α from the stage number sensor 5 is controlled by the calculation control means 2 so as not to be detected.

After performing this complete version, the operator selects the input means 1
The operated key 101 is operated. Accordingly, the arithmetic control means, based on the signal from the operated key 101, selects the main part M3 stored in the storage means 3.
Return the number of rows to 1, and select "Stitch stitch" on the display means 4 so that section C is stitched in the same way as in the above case.
is displayed.

Thereafter, the operated key 101 is operated. Then, by operating this operated key 101, part B
The number of stitches in the first row, that is, the main part M3 is displayed, and the operator knits up to the main parts M4 and M5 in the same manner as the above-described knitting operation for part A. When the main part M5 of part B is knitted, the number of rows comparing means 6 detects that the number of rows matches, and a matching signal is inputted to the calculation control means 2. Therefore, the arithmetic and control means 2 causes the display means 4 to display that the knitting operation for this portion B has been completed and that a second knitting is required.
If the operator operates this operated key 101 after knitting a desired number of rows, the calculation control means 2 determines that the knitting operation of the front body pattern shown in FIG. 1 has been completed. Then, the display means 4 displays a message such as "End".

As mentioned above, the end of each edition operation (for example, M
In the case of 5), the end is automatically detected by the end detection means and the next operation is automatically displayed, whereas in the case of the end of the straight knitting, the operator operates the already operated key 101. The reason for this is that, as mentioned above, the final knitting is influenced by the artificial judgment of the knitter, and this This is because manual input is more convenient in the case of knitting.

FIG. 4 is a block diagram showing FIG. 2 in more detail. Here, in the case of knitting the front body pattern shown in FIG. 1, the operations or movements shown in FIG. 4 will be explained. The operator first inputs the name of the work he or she wishes to knit and the address code of its standard pattern through the input means 1, and selects and instructs the desired pattern. Next, the gauge key 11 and the numeric keypad 13 are operated to input the number of gauges and the number of gauge stages. At the same time, the desired size L
Or to specify S, press the "L" key 103
Alternatively, operate the "S" key 104. In addition, M
If you want to change the size, there is no need to operate these keys 103 and 104. Next, the operator presses the "front body" key 121 of the partial keys 12 in order to knit the front body part shown in FIG. In this way, the initial setting of this device is completed.

Subsequently, the calculation control means 2 calculates the number of stitches and the number of rows of the main parts M1 to M5 of this pattern based on the information from the input means 1 and the information of the standard pattern stored in the storage means 3. , is stored in the area of the storage means 3. On this occasion,
The number of stages of the main part M3 (for example, "200") is stored in the area 31 of the storage means 3, the number of stages of the main part M5 (for example, "250") is stored in the area 32, and the parts A and B in this main part M3 are stored in the area 33. The initial number of stitches a in the area 34 is set to the number b of stitches in the main part M4.
and the number of stitches c of the portion C of the main portion M3 are stored in the area 35, respectively. After each piece of information is stored in the storage means 3 in this way, the knitting operation is started next.

In the knitting operation, the operator first moves the knitting needles to the knitting position by the number of stitches displayed in the display area 412 of the display section 41 of the display means 4 in the first row, that is, the initial stage, to perform set-up, and then the knitting machine Operate the main unit's carriage. Accordingly, the pulse signal α from the stage number sensor 5 is applied to the stage number register 21 of the calculation control means 2 via the AND gate 609 included in the stage number comparison means 6. Therefore, the content of the stage number register 21, that is, the stage number display displayed in the display area 412 is increased by one stage, and the operator can:
Perform knitting operations according to the instructions and knit. Note that the display area 411 of the display unit 41 is, for example,
The increasing or decreasing stitches on the left side of the pattern are displayed, and the display area 413 displays the increasing or decreasing stitches on the right side of the pattern. Then, in the display area 412,
In some cases, the number of stitches is displayed, and in other cases, the number of rows is displayed. And gate 60 included in the stage number comparing means 6
9, that is, the output of the NOR gate 607, is normally "1", and the pulse signal α from the stage number sensor 5 is to be applied to the arithmetic control means 2.

Here, it is assumed that the main part M3 of the pattern shown in FIG. 1 has been knitted, that is, up to 200 rows. At this time, "200" is also counted in the stage number register 21 of the arithmetic control means 2, and therefore a coincidence signal is derived from the detection circuit 602. The coincidence signal from this detection circuit 602 is sent to the AND gate 60
4 and 625 are given as one input.
Here, flip-flops 613 and 62 for distinguishing parts A, B, and C of the pattern in FIG.
1 has been initially reset, and its outputs R and L are "0", that is, the outputs R and L are "1". Therefore, "1" is derived from this AND gate 625, and the "return" display 423 is displayed on the display section 42 of the display means 4. At the same time, the number of stitches in the main portion M3 (stored in the area 33 of the storage means 3) is given to the display area 412 of the display means 4 via the AND gate 626 and displayed. This results in
The operator selects (a +
Move the knitting needle to the needle rest position by c), and select the number of stitches a on the left.
Operate so that you can only knit. In this way,
Knit the remaining part A. In the knitting operation of this part A, when the main part M5 is knitted, that is, the 250th row, the number of rows stored in the area 32 matches the contents of the row number register 21 of the arithmetic control means 2, and the detection is made. An output of "1" is obtained from the circuit 603. Flip-flop 606 is set accordingly. As a result, the "old edition" included in the display section 42 of the display means 4 is displayed through the OR gate 608. Further, the number b of stitches of the last stitch is displayed through the AND gate 624. The operator follows this display and
Make a second stitch with the number of stitches b. Note that it can be seen that the number of stitches of the last stitch here is the number of stitches b stored in the main section M4. In this last edition, the pulse signal α from the stage number sensor 5 by the carriage is blocked by the AND gate 609 because the output of the flip-flop 606 becomes "1" and the output of the NOR gate 607 becomes "0". and is not given to the arithmetic control means 2.

Thereafter, the operated key 101 of the input means 1 is pressed. After being delayed for a predetermined time by delay circuit 601, this key 101 press signal is applied as a reset input to flip-flops 605 and 606. At the same time, this operated key 101
The pressing output is given to the AND gate 614. Therefore, when this operated key 101 is pressed, this AND gate 614 becomes the output "1" of the flip-flop 606 (which remains set immediately after this key 101 is pressed due to the action of the delay circuit 601). Therefore, this AND gate 6
14 becomes "1", and flip-flop 6
16 is set. After the delay time of the delay circuit 601, the flip-flops 605 and 60
6 is reset and its output becomes "0". At this time, flip-flops 613 and 621
Since both have been reset, their outputs and are "1". Therefore, all three inputs of the AND gate 617 become "1", and the output of this AND gate 617 becomes "1". In response, flip-flop 618 is set and AND gate 619 is opened. Therefore, the number c of stitches stored in the area 35 of the storage means 3 is displayed in the display area 412 of the display means 4. Furthermore, the AND gate 620 is opened by the output of the AND gate 617, and the stage number "200" stored in the storage area 31 of the storage means 3 is given to the stage number register 21 of the arithmetic control means 2. Therefore, this stage number register 21 is set to "200". At this time, the flip-flop 621 is set and its output L becomes "1".

“200” is set in the stage number register 21,
Since the number of stages matches the number of stages of the storage area 31, a detection output of "1" is obtained from the detection circuit 602, and the flip-flop 621 is set.
AND gate 604 is opened and its output is "1"
becomes. In response, flip-flop 605 is set and its output becomes "1". Therefore,
Through the OR gate 608, the "Save Edition" display 421 on the display section 42 is lit. In accordance with this display of "empty stitches", the operator pushes in the knitting needle by c out of the number of stitches (a+c) that were previously moved to the needle rest position, and performs the abandoned stitches by an arbitrary number of rows. In this case as well, since the flip-flop 605 is set, the pulse signal α from the stage number sensor 5 is sent to the AND gate 6.
09, and is not applied to the register 21 of the arithmetic control means 2. Therefore, this stage number register 201 remains set at "200".

After that, when the operated key 101 is operated, the flip-flop 605 is reset and the
Display 421 turns off. Also, since the flip-flop 613 is in the reset state and the flip-flop 621 is in the set state, the AND gate 6
15 becomes "1", and flip-flop 6
16 and 618 are reset. Accordingly, the number of stitches c displayed in the display area 412 also disappears. However, at the same time as the operated key 101 is operated,
Since AND gate 610 is opened, flip-flop 611 is set and AND gate 612 is set.
The number of stitches a is displayed in the display area 412 via. In this case as well, since the input of the operated key 101 to the AND gate 610 is not passed through the delay circuit 601, the flip-flop 611 is set before the flip-flop 605 is reset.
Furthermore, when flip-flop 611 is set, flip-flop 613 is also set.

Here, the initial stitch number a of part B in FIG.
When this is displayed, the knitting needle is pushed in by the number a of the stitches (a+c) that were previously moved to the needle rest position, and the carriage is operated to knit one row at a time. By this operation of the carriage, the stage number register 21 of the arithmetic control means 2 is incremented, and when the content reaches "250", the detection circuit 603 outputs "1".
The output is obtained. The flip-flop 606 is set by the output from the detection circuit 603, and its output becomes "1". In response, the display section 42 displays the "old edition" via the OR gate 608. Along with that, and gate 62
4, the number of stitches b of the last stitch is displayed in the display area 412. Therefore, the operator performs the waste knitting for an arbitrary number of rows and operates the operated key 101 in the same way as the previous time. Accordingly, and gate 61
Since flip-flop 616 is set through 4 and flip-flops 613 and 621 are set, an output of ``1'' is obtained from AND gate 622. In response, the "end" display 422 included in the display section 42 of the display means 4 is lit. At the same time, "0" is displayed in the display area 412 through the AND gate 623.
In this way, the pattern of the front body shown in FIG. 1 is knitted. In addition, flip-flop 61
1,613, 616, and 621 remain set, but they can be reset to the initial state when creating the next work.

It goes without saying that the specific processing or calculations described in the above-described embodiments may be processed by a microprogram using a microprocessor that is currently in general use.

As described above, according to the present invention, the pattern to be knitted is divided into a plurality of parts corresponding to the actual knitting operation and stored, and the waste knitting operation is performed in accordance with the completion of the knitting operation of each part. Displaying the contents of the instruction, in response to the input signal from the operated signal input means,
When the next knitting operation is a flechage, the end of a knitting operation, or a droop stitch, selectively displays the contents instructing the flechage, the end, or the droop stitch, respectively, and also displays information regarding the number of stitches required for the knitting operation. Since the information is displayed, the operator only has to perform the knitting operation according to the instructions, and it is possible to prevent the operator from performing the wrong knitting operation. Moreover, since the operated signal input means allows artificially inputting information on the operated information, even when it comes to regular knitting, which requires the operator's artificial judgment, the operated This can be handled by inputting signals, making it possible to perform editing operations that incorporate human judgment.

It can also be used to knit parts such as the sleeves of a sweater or the placket of a cardigan, and for example, to process the M3 part of the pattern example by stitching, making it extremely useful.
