Description

[Detailed description of the invention]

The present invention relates to an electronic control device for a knitting machine, and in particular 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 or drawing the object to be knitted are extremely troublesome for many general users. 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 However, even in this proposed knitting machine, instructions are only given by displaying the number of rows and the number of increasing/decreasing stitches for each row as knitting information, and the actual needle position information at that time is not displayed. I couldn't give instructions. For this reason, if the number of increasing stitches or decreasing stitches in each displayed row is incorrectly confirmed (for example, if the number of increasing stitches is incorrectly confirmed as "5" even though it is "3"), the knitting may be interrupted. When I go there,
After the erroneous confirmation occurs, the size of the knitted fabric will be different from the preset regular size. In extreme cases, knitting may occur based on this information that has been erroneously confirmed until the end. In this case, the yarn must be unraveled to the row number position where the erroneous confirmation occurred and knitted again. Therefore, the present invention provides an electronic control device for a knitting machine that displays needle position information for each row as knitting information so that the number of stitches corresponding to a regular pattern, that is, the needle position can be checked at all times. To summarize, the present invention provides a storage means for storing left and right increase/decrease stitch number information, total stitch number information, left and right stitch number (needle position) information, and row number information corresponding to a desired pattern to be knitted; In connection with
Each time the carriage passes a predetermined position to knit a desired pattern, it is equipped with a display means that displays information on this pattern as knitting information, and displays information on the number of left and right increase/decrease stitches, total number of stitches, and number of left and right stitches (needle position). ) information and row number information can be switched and displayed by operating a specific key. The above objects and other objects and features of the invention will become more apparent from the following detailed description with reference to the drawings. FIG. 1 is a block diagram showing the main parts of an embodiment of the present invention. In the configuration, the input means 1 is for inputting the pattern, gauge value, size, part, left and right, etc. to be knitted, such as a chiyotsuki or sweater.
As shown in the figure. Based on the instruction input information input from the input means 1, the arithmetic control means 2 performs the first
A combination of standard patterns stored in the storage means 3 is selected. Then, the selected pattern and
Based on the gauge value and size entered,
The number of stitches and number of rows at the main points are calculated. Information calculated and obtained by the calculation control means 2 is stored in a predetermined position of the second storage means 4. Therefore, the first storage means 3 stores information on at least some standard patterns, and the second storage means 4 stores information on at least some standard patterns.
has an area for storing calculation results from the calculation control means 2. The display means 6 displays, for example, the number of stitches, widening stitches,
It displays information such as reduction. and,
For example, the row number sensor 5 detects one row each time the carriage passes a predetermined position (for example, the center) of the knitting machine.
A signal indicating the completion of one stage of knitting operation is input to the arithmetic control means 2. Based on the pulse signal α from the row number sensor 5, the calculation control means 2 causes the display means 6 to display how many rows of the desired pattern have been knitted. Also,
In the arithmetic control means 2, the step number information formed by the pulse signal α receives the increase and decrease information stored in a predetermined area of the second storage means 4, and combines this step number information with the second storage. A match with the information from the means 4 is detected, and it is detected whether the next knitting operation is a widening stitch or a decreasing stitch. That is, if this stage number information matches the information in the storage means 3, the next operation is displayed on the display means 6 via the calculation 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. In the above-described embodiment, the storage means is shown as being divided into the first and second parts, but it goes without saying that different storage areas of one storage means may be used. One feature of this invention is the confirmation key 101 provided on the input means 1. This confirmation key 101
is a key to be operated to switch and display left and right increase/decrease stitch number information, total stitch number information, left and right stitch number (needle position) information, and row number information. FIG. 2 is an illustrative diagram showing a control section of the knitting machine including input means 1 and display means 6. As shown in FIG. Here, the operation of this input means 1 will be briefly explained with reference to FIG. When specifying what you want to knit, use the numeric keypad 13 to enter the address codes of standard patterns for multiple works stored in a predetermined area of the storage means 3 in advance, and then enter the "work name"
Press key 102. Further, when inputting a gauge value, the gauge key 11 and the numeric keypad 13 are used. That is, when inputting the gauge number, the numerical value is input using the numeric keypad 13, and then the "gauge number" key 111 is pressed. Further, when inputting a gauge stage, the numerical value is first input using the numeric keypad 13, and then the "gauge stage" key 112 is pressed. 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, the part key 12 determines which part of the work specified by the "work name" key 102 is to be knitted.
"Front body" key 121, "back body" key 122
Alternatively, it is specified using the "left" key 123, "right" key 124, etc. If you want to know the section where the number of stitches does not change, press the "X" key 106,
The section can be searched and displayed on a display means or the like. The "operation" key 105 is 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 shown in FIG. 1 will be explained. First, depending on whether the operator wishes to knit anything, the operator operates the "work name" key 102 and the numeric keypad 13 to select a standard pattern such as a twill pattern or a sweater pattern. When a desired standard pattern is designated by the input means 1, the input information is given to the arithmetic control means 2. The arithmetic control means 2 calculates the number of standard patterns necessary to form the desired pattern from among the plurality of standard patterns stored in a predetermined area of the storage means 3 and calculation formulas such as the number of stitches or the number of rows of each part of the patterns. Select and specify information. Next, the operator performs test knitting using the yarn used for knitting the desired pattern, and determines the number of stitches and rows per 10 cm of the yarn (the "gauge value") and the predetermined measurement value (here, the standard value is used). input.
However, if it has been set in advance, it is not necessary to input it) using the gauge keys 11, numeric keypad 13, etc. of this input means 1. These gauge values and measurement values are given to the arithmetic control means 2, and in the arithmetic control means 2, based on the information of the desired pattern from the storage means 3, information necessary for knitting this pattern (e.g. It is obtained by calculating the number of increasing stitches/number of decreasing stitches, total number of stitches, number of rows, and number of stitches (needle position); "knitting information"). The edition information thus obtained is stored in a predetermined area of the second storage means 4 by the calculation control means 2. 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 6.
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 6 to display how many rows of the pattern of the desired size have been knitted. Further, it is 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 stitches and subtracting stitches stored in a predetermined area of the second storage means 4. Then, the operator causes the display means 6 to display information such as the number of stitches of the next row, increasing stitches, decreasing stitches, etc.
Following these instructions, the operator moves the knitting needle to the knitting position for the specified number of stitches in the case of widening, and moves the stitches from the knitting needle to the knitting position for the specified number of stitches in the case of shortening. Remove. The knitting operation is continued by repeating such displays or instructions and operations. FIG. 3 is a block diagram showing the main part of the invention in more detail. Next, this embodiment will be explained in more detail based on FIG. The knitting information necessary for producing a knitted fabric with a desired pattern, that is, the number of increasing/decreasing stitches in each row, is calculated in advance as described above and is stored in the second storage means 4. . Now, when knitting Chiyotsuki as shown in the drawing in Figure 4, the total number of stitches corresponding to 0 rows (160 in Figure 4), the number of left and right stitches when the center of the knitted fabric is taken as a reference, that is, the number of left and right stitches. The needle position information ("80" in FIG. 4) is calculated in advance and stored in the storage sections 42, 43a, and 43b of the second storage means 4. The stage number storage section 44 that stores the accumulated value of the pulse signal α generated from the stage number sensor (not shown in FIG. 3) 5 is "0". In the initial state, when the confirmation key 101 is not operated, the flip-flop circuit 201 outputs the signal c.
It has been reset by. Therefore, AND gates 203 and 206 are open. Therefore, the total number of stitches stored in the storage unit 42 of the second storage unit 4 is displayed on the display unit 6 of the display unit 6 via the AND gate 203 and the OR gate 204.
12, and gate 206 and OR
Via the gate 207, the number of left and right increasing/decreasing stitches corresponding to the 0th row (the initial setting number of stitches in the case of the 0th row) stored in the storage units 41a and 41b of the second storage means 4 is displayed on the display means 6. Sections 611 and 61
given to 3. Therefore, in this state, the number of left and right increasing/decreasing stitches, that is, the initial setting number of stitches "80" is displayed on the display sections 611 and 613, and the display section 6
12 displays the total number of stitches "160". In this state, the operator moves the knitting needles to the knitting position by the number of stitches in the 0 row displayed by the display means 6 to perform set-up. Next, by operating the carriage of the knitting machine main body, a pulse signal α is obtained from the row number sensor 5, and the contents of the row number storage section 44 are increased by "1". Accordingly, the second storage means 4
The next address of the storage unit 41 is specified. Therefore, at this time, the storage section 61 of the storage means 6
1 and 613 contain the contents of the first row, that is, “+
1” and “+1” are displayed. As described above, at the same time as the contents of the next address in the storage section 41 of the second storage means 4 are output, the calculation signal X is generated and the AND gate 208 included in the calculation control means 2 is opened. Therefore,
This AND gate 208 and OR gate 210
The contents of the first stage "+1" and "+1" are applied to one input of the adder/subtractor 211 via the adder/subtractor 211. Other inputs of this adder/subtractor 211 are given the number of stitches, that is, needle position information stored in the storage sections 43a and 43b of the second storage means 4. Therefore, this adder/subtractor 211 adds and subtracts the two inputs to obtain the numbers of left and right stitches in the first row, "81" and "81". This left and right stitch number gator is stored in the storage sections 43a and 43b of the second storage means 4 via the AND gate 213. Then,
A calculation signal Y is generated. Therefore, AND gate 209 is opened. Accordingly, the number of left and right stitches in the storage sections 43a and 43b is given to the adder/subtractor 211 via the AND gate 209 and the OR gate 210, and the total number of stitches in the first stage is "162" in the adder/subtractor 211. get. This total stitch number data is stored in the storage section 42 of the second storage means 4 via the AND gate 212. Such calculations are executed every time the carriage is operated, and the data corresponding to each second storage means 4 is stored sequentially based on the number of stages as shown in the following table.

[Table] When the carriage is operated to knit a knitted fabric, the display sections 611, 612, 61 of the display means 6 are displayed.
3, the storage section 41 of the second storage means 4, respectively.
The number of left increasing/decreasing stitches of a predetermined row stored in a, the total number of stitches stored in the storage section 42 of the storage means 4, and the right increasing/decreasing stitches of a predetermined row stored in the storage section 41b of the storage means 4. The number is displayed. If the operator knows only the increase/decrease in stitches relative to the previous row, he or she can knit the fabric with almost no errors. However, it is possible to misjudge the value of the number of increased or decreased stitches and continue knitting as is. In this case, it is necessary to confirm whether the number of left and right stitches to be knitted now corresponds to the preset pattern. Confirmation or display of this stitch number will be explained below. In the case of the pattern shown in FIG. 4, it is assumed that this confirmation is now performed in the fifth stage. First, for confirmation, the "confirmation" key 101 included in the input means 1 is operated. Accordingly, the flip-flop circuit 201
is set. This flip-flop circuit 20
A set output of 1 opens AND gates 202 and 205. Therefore, via the AND gate 202 and the OR gate 204, the number of stages stored in the storage section 44 of the second storage means 4 is given to the display section 612 of the display means 6 and displayed. At the same time, the number of left and right stitches (that is, needle position information) stored in the storage units 43a and 43b of the second storage unit 4 is displayed on the display unit 6 via the AND gate 205 and the OR gate 207.
is applied to the display sections 611 and 613 of and displayed. Therefore, the operator can check the displayed number of left and right stitches (display sections 611, 613) in comparison with the number of stitches of the yarn currently set on the knitting needle. That is, by operating this "confirmation" key 101, the number of left and right stitches can be confirmed, and it can be easily determined whether there is a knitting mistake. If there is an error in the number of stitches, simply unravel the yarn to the number of rows knitted with the correct number of stitches and repeat the knitting operation. Note that if you operate the "confirmation" key 101 to confirm the display and then operate the carriage again, the signal c
is obtained. Therefore, flip-flop circuit 201 is reset by this signal c.
Therefore, AND gate 202, which was opened earlier,
and 205 are closed while the other AND gates 203 and 206 are opened. Therefore, in this state, the display sections 611 and 613 display the number of left and right increase/decrease stitches, and the display section 612 displays the number of rows. FIG. 5 is a block diagram showing the main parts of another embodiment of the invention. In the embodiment shown in FIG. 3, an RS flip-flop is used as the flip-flop circuit 201, but in the embodiment shown in FIG. . In this case, each time the "confirm" key 101 is operated, the above-mentioned display is switched. That is, when the "confirm" key 101 is operated for the first time, the display shown in FIG. 6a is displayed, and when the "confirm" key 101 is operated for the second time,
The display shown in Figure b is then displayed. Furthermore, each time the "Confirm" key 101 is operated, the
The display with Figure b is alternately displayed. In addition, in the above-mentioned embodiment, the first
The display state (display of the number of left increasing/decreasing stitches, the total number of stitches, and the number of right increasing/decreasing stitches) and the second display state (displaying the number of left stitches, number of rows, and right stitch number) shown in FIG. However, if separate display parts corresponding to the first display state and the second display state are simultaneously displayed, the number of stitches (needle positions) can be further changed. can be accurately confirmed. If a switching display is used, the display section can be simplified, and the knitting machine control device itself can be made compact and can be operated by simple key operations. As described above, according to the present invention, information necessary for the knitting work (for example, the number of left/right increase/decrease stitches and the total number of stitches) is obtained during the knitting work, and when it is necessary to confirm the knitted fabric stitches, the information necessary for the confirmation is obtained. Information (for example, the number of left and right stitches) can be displayed on the same display section.
Further, by re-operating the carriage, the information necessary for confirmation is automatically returned to the information necessary for organizing work, so that the confirmation operation and subsequent operations can be made simple and reliable. Therefore, by using this device, it is possible to provide a knitting machine that is easy to operate and can accurately display necessary knitting and confirmation information.
