Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides variable values based on trial knitting samples or experience, taking into account the thickness of knitting yarn, the density and density of knitting structures, etc. Examples include ゛ (yellow),
Enter the number of stitches per Oc+i and the number of tiers per 10c of vertical louse as the gauge designation value using the numeric keypad, and based on that, calculate the body weight, body length, sincerity, and curve of the widened part written in the knitting drawing. Calculate the actual size of diagonal straight lines, etc., and the reduction and increase values of straight lines or curves based on the dimensions cut in one section according to the drawings, etc., as required for practical skill! It N L
, or the "number of stitches" of the whole or part of the knitted fabric [number of rows]
It relates to a 61 calculating machine for knitting drafting index which calculates the numerical value of ll and visually outputs the calculated number as described above using a printer, display board, etc. so that it can be used for practical knitting skills, and is particularly useful for knitting. This allows you to easily determine the specific numerical values of the number of months of increase/decrease in the arc portion of the "sleeve cut" and "eye cut" which are frequently used in drafting, and the number of stages.

When braiding a knitted fabric, the knitting fabric drawing 10 illustrated in FIG.
It is normal to do 1. However, the practical skills of knitting are decreasing,
(1) When knitting continues while reducing stitches, (I) Knitting is done by reducing stitches in a concave arc shape (Fig. 2 I) (I) Knitting stitches are knitted in a convex arc shape. Nigeru type (Fig. 3 I)
) (1) There is a type where the stitches are knitted in a diagonal straight line. (2) When the stitches are increased without increasing the stitches (lsr) there is a type where the stitches are knitted in a concave arc shape (4th drawing). (V) There is a type where the stitches are increased in a convex arc shape and knitted with Ha-, 1: Geroya Eve (fifth drawing) (W) Diagonal ni cotton linear stitches are increased and knitted.

However, in the case of the type 1) in which the knitting progresses while decreasing the stitches in a diagonal straight line, in the case of the type (1) or (I [), the value of the C arc height C) is the number direction 1 method (a) step direction It is omitted because it is included if it is very small or zero compared to each value of the 1J method (1n) 6. The (■) type is also included in the (fi') (V) type for the same reason as above. omitted from.

(I) (I[) (M) (V) The outline lines of each type of knitting drafting part are all made of circular arcs that are part of a circle, so they can be processed using the quadratic equation of a circle. .

In the present invention, coordinates must be determined in order to express the above equation, but here, for convenience, rectangular coordinates are used in which the origin (0, 0) of the coordinates is located at the lower left corner of the knitted fabric drafting section. For example, in the case of type (1) (I[), if the starting point of the arc is the coordinate (a, O), the end point of the arc is the coordinate (0, b), and the height of the arc is C, then the values of a, b, and C The equation of the circle is determined by

In addition, in the case of type (IV) (V), the starting point of the arc is the origin (0
, 0), the end point is the coordinate (a, b), and the height of the arc is C, the equation of the circle is determined.

Explanatory diagrams of the arcs of the above types (I), (n), (17), and (V) are shown in FIG. 2I to FIG. 51. In addition, equations of circles corresponding to each of these figures are shown in Figures 2-2 to 5-3.

All of these calculation functions for the equation of the circle are permanently stored in the calculator of the present invention, and are called up by a designation button in the indexing location designation display field, which will be described later.

In addition, there is a constant (d) that includes zero from the reference line of the knitting fabric drawing 101 (in most cases it is the vertical center line, but there are exceptions) to the origin (0.0). However, since the purpose of the main function ψ is to increase or decrease the number of stitches, the constant d will be omitted for the sake of explanation.

The above-mentioned symbols a to d refer to the dimension values already mentioned, but since they are commonly used for the knitted fabric H, they can be understood most easily by drafters.

However, the height C of this inner arc requires the most troublesome procedure to determine the value compared to a, b, d, etc. of the knitting drafting index. An example of how to measure the height of an arc that is commonly used at present will be explained with reference to Fig. 6. The dimension b is the same as in the present invention).

First, the lengths of the two sides OA and OB that sandwich the right angle are a and b.
Create a right triangle OAB. and the midpoint m of side AB
(a /2. b /2), then m and 0 (0,
The midpoint of the straight line connecting 0) is n (a / 4., b /
4). And A (a, Q) and n and B (0, b
) is a song called ``Sodeguri'' or ``Eriguri'' that depicts an arc that passes through the circle. Therefore, the value of C is the dimension from n to the point where a perpendicular line is drawn to side AB and intersects with the circular arc.

The places where such arcs are used in knitting drafting are ``sodeguri'' and ``eriguri'', etc. most often, and the dimensional ratios of a and b used to tighten the arcs are not that big, and generally speaking. a:b=I:1 to 1:1.5.

Therefore, there may be no practical problem even if the value of the arc height C is determined by multiplying the a or b O) value by a certain proportionality constant, for example, C = 0.3a or C = 0.3b. many. By determining the value of a or b in this way, the value of C can be automatically calculated using the above formula.
The 6F rate increases significantly when using a calculator. The present invention also allows calculations to be made using proportionality constants as described above.

However, in the case of a circular arc of a special shape, if the value of C is calculated from the knitting fabric drawing and inputted into the calculator, it is possible to obtain a calculator for indexing the knitting fabric drafting part very efficiently and with a wide range of applications. I can do it.

In addition, in the case of the knitted fabric for which index calculation is to be performed, the calculator of the present invention inputs the numerical values of the number of months and the number of rows per 1 oat as described below, but in the subtraction machine, the numerical values of the husband etc.
An arithmetic function for calculating division by 0 is permanently stored.

That is, it has a function of calculating the pitch per stitch (represented as Px) and the pitch per step (represented as P31) and temporarily storing the values.

The calculator of the present invention, which has the above-mentioned unique arithmetic function for knitting drafting indexing, is operated according to the steps illustrated in the flowchart of M8 diagram (the lowchart shows the quiz (1)).

Below is an explanation based on the above flowchart.
The first step is 10c obtained by one measurement of the test knitted fabric.
The numerical values for the number of stitches per m and the numerical values for the number of steps are manually entered. The meter is based on its human power and performs the calculation functions described above to calculate P.
Obtain and temporarily store the values of x and py.

The second step is to select the index location (A).

In the third step, the numerical values of dimensions a and b of the knitted fabric drawing part are input.

The fourth step is to select whether or not to manually enter the dimension values for C. Here, the case where no input is made (the gist of the present invention) will be explained.

The total n value of C=0.3a is used as the numerical value of C. In the fifth step, the total number of machines calculates equations (1a) (1bNlc) - see Figure 2 (2) - and temporarily stores the numerical values of T, α, and β.

The 6th step is y=N I) 3T・・・・・・・・・・・・(
6) Calculate y (where N is O and 1...2.3...positive number) and temporarily store the value.

The seventh step is γ and α determined in the fifth step.

Substitute β and the value of y found in the 6th step into equation (1) (see Figure 2) and note the value of X. 8th step is the value of X temporarily stored in the 7th step P
Divide by x, round off the obtained value below the small value point (rounding up, rounding down, rounding to the nearest whole number, etc. is also possible) - Special note t1
do. This positive value is [x / P x ]...
...... Expressed as (7). This value becomes the number of stitches in the Nth row of the knitting fabric drafting section.

The 9th step is the number of lls in the Nth stage determined in the 8th step,
Calculate the difference in the number of general (N, 1) stages.

Number of stitches in the Nth row - (N-1 > 11 losses in the row = Number of decreases (or increases) when knitting the Nth row... (8) - (I) (I[) The type of is the number of subtractions (N) (
In the case of V), the number of increases is determined.The 10th step is to output and display the numerical values of N (number of stages), [x/Px] (number of times), and decrease (increase) determined above using a printer, etc. The 11th step is to compare the value of y determined by equation (6) with the value of the constant example B[) determined at the beginning. Then, if the condition (9) is satisfied, y≦b, then return to the sixth step and calculate y=(N+1)P3'. Repeat the same steps as before. However, equation (9)
If the condition is no longer satisfied, the "index calculation function" is stopped.

The constants to be compared in the [l] step are t in b and A
<The following numbers may be used. Immediately [b/Px]
=N This is the dimension in the direction of the number of rows on the drafting part of the knitted fabric.
) A positive number obtained by dividing by X, rounding off the decimal point and the bottom of the answer, and means the total number of columns on the drafting part.

A preferred practical example of the subtraction machine main body 1 of the present invention is shown in the seventh example.
This will be explained using figures.

In addition, a printer blank feed push button switch 9 is provided.

Inside the computer main body 1, there is provided a permanent memory memo IJ-3 temporary memory for arithmetic functions, which constitutes a well-known electronic 4I arithmetic device.

The basic operation of the indexing computer of this embodiment will be explained.

◎Start-up operation◎ [1] When the power switch 5 is turned on, the display lamp (J+) of the input device display 11ii (J) and the number display lamp (K1) of the gauge designation column (K) blink.

◎Manual power of gauge◎ 1] Manually input the number of gauge stitches per 10 cm of the trial crystal prepared in advance using the numeric keypad 7 of the human power display 1rtl (J), for example, 14, and display the human power value on the liquid crystal display board 6. Saze de ff! After confirming, press the number of stitches button (K3) in the gauge specification field (■().The BJ calculator calculates and memorizes the number of stitches Px = 0.71cB from the gauge number number A mentioned above. .

As a result, the row number display lamp (K1) goes out, the row number display lamp (K2) blinks in its place, and the liquid crystal display board 6 shows "0".
Display numbers. At the same time, the printer outputs a printout as shown in FIG. 9(a).

2] Manually enter the number of gauge stages per 10 cm of the trial product, for example 23, using the numeric keypad 7, display the input value on the liquid crystal display board 6 to confirm it, and then press the stage placement button (K4). The computer determines and stores the step number pitch P y =0.43 from the gauge step number values in 1iiJ.

As a result, the stage number display lamp (K2) goes out, and instead the display lamps (AI) (B blind) (C+) (D+) blink, respectively, and the liquid crystal display board 6 displays the number "0".

At the same time, printing is additionally outputted as shown in FIG. 9 (b) by plinking.

0 Specifying the indexing location ◎ There are four indexing locations (A) to (D) on the keyboard 2, and the required location is specified by referring to the knitting drawing 101, but the operation is by pressing button (A2) - (B2) to select. Here, the case when the push button (A2) is pressed will be selected as a representative example.

1] When the push button (A2) in the display field (A) is pressed, the display lamps (B1) to (Dl) that were flashing until then go out, only the display lamp (AI) lights up continuously, and the display lamp (J ■) and (L,) are blinking, and the formula (1) (I a ) (1b ) (I c ) corresponding to display field (A) is waiting for calculation, and the numerical values of a, b, and c are Announce that preparations are complete. At the same time, the printer outputs additional print as shown in FIG. 9(c).

The meaning of the print rMODEAJ will be displayed from now on11i
It indicates that preparations are ready to execute type (A) type of indexing operation, and the first number *1* indicates that the knitting drafting is divided into multiple drafting parts, and each part is selected from the appropriate type from the display column. This is a number that represents the order of selection and sequential indexing operations.

2] Use the numeric keypad 7 to enter the dimension value of a in the knitting drawing in cm.
For example, in this case, 5.2 is input manually, and the liquid crystal display board is 6.
Display and confirm the human power value.

3] Next, press the push button (K5) in the dimension and location designation field (L) to temporarily store the manpower number 5.2 in a.

As a result, the display lamp (Ll) lights up continuously, the display lamp (B2) and the display lamp (J+) blink, and the liquid crystal display board 6 displays the number "0".

At the same time, printing is additionally outputted as shown in FIG. 9(d) by plinking. The reason why () is added to a here will be explained in detail later, but since the human force value of a and the practical dimension value are generally different, () is attached to the human force value, and the practical dimension value is not. ) will not be added.

4] Enter the dimension value of b (in units of 1, for example, 6.7 here) using the numeric keypad 7, and display the input value on the liquid crystal display board 6 for confirmation.

5] Next, press the push button (B2) and set the manual power value 6
．． 7 is temporarily memorized.

As a result, the display lamp (B2) changes to ren J, Jl! lights up,
At the same time, the display lamp (shi3) and the display lamp (, J+) blink, and at the same time, the selection display lamps (Ml) and (M2) of the printer llii (M) also blink, and the liquid crystal display board 6 shows "0".
” Display numbers. At the same time, the printer additionally outputs the characters <Li2 as shown in FIG. 9 (e). Here, the parentheses attached to b indicate that (b) is the input value (ideal value), as in (a).

6] Here, select whether to input the C dimension or not manually.

The following is an explanation when no selection is made.

Here, to explain the difference between the above-mentioned input values and practical dimension values, the human power values are, for example,
The dimensions are the same as those of "Tangled Drafting", and they are the ideal dimensions, so to speak. For example, the j method on the knitted fabric that Tokoro knitted in practice is a-
For the 4th dimension, it is a positive multiple of the pitch Px per stitch, and for the 5th dimension, it is a positive multiple of the pitch Py for one step, so they do not necessarily match the dimensions on the drawing.

In the present invention, when a dimension value is input, that value (a) is divided by the already stored Px, and the obtained value is rounded off to the nearest whole number (rounding up, rounding down, or rounding down to the nearest whole number is also possible. ) to a positive value and temporarily store it.

This will be expressed as [(a)/Px']. Multiply this by Px and a = [(a)
/Px]xPx ·−·−(8) is calculated. This formula (
8) are the three dimensions in practical knitting skills, and the b 1J method in practical knitting skills is expressed by the following formula % formula % (9) Substituting the body values of this example into formulas (8) and (9), P x=10/14=0.71cmP3'=
10/23 = 0.43cm = [5,21
0.71 pieces X 0.71-7

7] To blink the selection display lamps (Ml) and (M2), calculate the number of stitches for each electrode film and output the plink, or calculate the number of stitches for every two stages and output to the printer. Since this prompts the user to make a selection, here the user selects the electrical installation link and presses the selection button (M3).

As a result, the electrical equipment selection indicator lamp (MI) lights up continuously, the electrical equipment printer starts to appear, and the electrical equipment selection indicator lamp (MI) lights up continuously.
2) disappears. Also, the indicator lamp (L!II) and indicator lamp (J) remained blinking because the C dimension was not manually adjusted.

At the same time, when we check y≦b, we find that 0.43≦6.9, which satisfies the condition, so we proceed to N=2, repeat the same procedure, and calculate N=3.4... The function is repeated until the condition y≦6 is no longer satisfied. Figure 1() shows what has been completely output to Blink.

When the blink-output is completed, the selection indicator lamp (MI)
disappears, and the display lamps for each designation +11I (A) to (D)
AI) to (Dl) flash, prompting selection of the next indexing location.

The present invention has the configuration and operation as exemplified above, and the stitch gauges normally used in knitting are manually memorized, and the stitch gauges are classified as (I) to (112) based on the memorization.
Select the indexing location on the &11 drawing using the indexing location designation button, and calculate the indexing by inputting the specific dimensions for each location in practical knitting. 61 Regarding the height of the arc in the "sleeve gore" and "eye gouge" parts, the 1 method (C) is proportional to the dimension in the stitch number direction (a) and the step number direction + fil = j' method (b). It was a calculation function added to the calculator that could automatically calculate Og4 based on relationships, and was essential for index calculations (C)
This has the effect of not only simplifying the operation by omitting the input of dimensions into the calculator, but also reducing the chances of erroneous operation when inputting numerical values.
