出来栄えは好ましいものではなかった(第1図参照)。(Prior art) Conventional embroidery machines sew line drawing embroidery using straight stitches or zigzag stitches (
Zigzag stitching is performed especially in curved sections because the needle bar is sewn with a slow amplitude movement in the lateral direction and the fabric is sewn with a reciprocating movement from side to side.
), the stitches become dense, and on the outside (O in Figure 1), the stitches become coarse, and the balance between the inside and outside is lost; ), the thread would swell and the quality of the embroidery would be unsatisfactory (see Figure 1).

In an automatic embroidery machine that is provided with a fabric tensioning frame that is supported so as to be able to move horizontally in time, and a control data storage unit that stores control data for controlling the horizontal movement of the fabric tensioning frame, Embroidery that is sewn by continuously dotting the basic structure along the line is D-Qog (n+Xnt/m)/Uog (1/1.41
D applying the fractal dimension shown by xN+/a)
It is characterized in that the values are approximately set in increments of 10.

A control data storage unit storing control data for horizontally driving the cloth tensioning frame 3 is provided within the sewing machine frame (see FIG. 8).
次に刺しゅう縫い方法について述べる。Next, we will discuss the embroidery sewing method.
一般に相似比rて縮小してN個の部分に分解できる幾何
学的形状は下記の基本式(1)により非整数の次元りを
もつ。該次元りが位相的次元よりも大きい場合フラクタ
ル図形と云われている。Generally, a geometrical shape that can be reduced and decomposed into N parts by a similarity ratio r has a non-integer dimension according to the following basic formula (1). If the dimension is larger than the topological dimension, it is said to be a fractal figure.
D −、Q ogN/Uog(1/r)=基本式(1)
上記の概念をミシンによる縫い方法に当てはめると次の
式(2)となる(第2図参照)。D −, Q ogN/Uog (1/r) = basic formula (1)
Applying the above concept to the sewing method using a sewing machine results in the following equation (2) (see Figure 2).
D=Uog(2xnxn、/N+)/Uogn−式(2
)但しn、縫目の長さ
N1・基本構成間の距離
n :N、の分割数
然し乍ら上記式(2)のり、はnの値によって大きく変
化してしまうのて、相似変換の見方を変えて前記式(1
)のNに対しては線分の数n3.1/rに対しては糸の
太さaに対する2つの基本構成の間の距離NIを夫々当
てはめ、更に基本構成の各線分の長さが均一でないので
重みづけをして平均長さをn2、ジグザグ幅をmとし、
そして縮小率1/rlの場合にジグザグ縫をすれば縫い
結果は面となるから、ここで次元り、は点の場合にはD
1=0、線の場合にはり、=1.面の場合にはDl−2
であるから、次元D1−2となるように定数1/1.4
1を式に入れる。D=Uog(2xnxn,/N+)/Uogn-formula (2
) However, the number of divisions of n, the length of the seam N1, and the distance between the basic components n: N. However, the glue in the above equation (2) changes greatly depending on the value of n, so we can change the way we look at the similarity transformation. The above formula (1
), apply the distance NI between the two basic configurations to the thread thickness a to the number of line segments n3.1/r, and furthermore, the length of each line segment of the basic configuration is uniform. Since it is not, weight it and set the average length to n2 and the zigzag width to m,
If the reduction ratio is 1/rl and zigzag sewing is performed, the sewing result will be a surface, so here the dimension is D if it is a point.
1=0, if line,=1. In the case of a surface, Dl-2
Therefore, the constant 1/1.4 is set so that the dimension is D1-2.
Put 1 into the equation.
以上により上記基本式(1)は次のようになる。From the above, the above basic formula (1) becomes as follows.
Dt−!Qog(n、xr+y/m)/Qog(1/1
.41xN+/a)・・・式(3)
上記式(3)のジグザグ縫(密着による)におけるD2
を求めると、N、=2a、n1=2、n2=mであるか
ら次のようになる。Dt-! Qog(n, xr+y/m)/Qog(1/1
.. 41xN+/a)...Formula (3) D2 in zigzag sewing (due to close contact) of the above formula (3)
Since N=2a, n1=2, and n2=m, we get the following.
D2−Uog(2xm/m)/ Uog(1/1.41
x 2 a / a)−Uog2zl!ogl 、41
= 2つまり2次元となり面として考えらか0る。D2-Uog (2xm/m)/Uog (1/1.41
x 2 a / a) - Uog2zl! ogl, 41
= 2, that is, it is two-dimensional and can be considered as a surface.
しかし現実には糸の太さ(a)、布の構造、模様の形状
等により曲線部にては縫が不可能となるから実験的に得
られる最良の縫い方法は次元がり。However, in reality, it is impossible to sew on curved sections due to the thickness of the thread (a), the structure of the fabric, the shape of the pattern, etc., so the best sewing method that can be experimentally obtained is multidimensional.
−1であることが解った。It turned out to be -1.
次に本発明による実験例を以下に示す。Next, an experimental example according to the present invention will be shown below.
例1・第3図に示す線Cに沿って縫う場合1−(1):
A部をN1−1Oa*とするとD=0.26B部をN、
=38とするとD=0.48*印はA部を現実に縫うこ
との出来る最小の値である。Example 1: Sewing along line C shown in Figure 3 1-(1):
If A part is N1-1Oa*, D=0.26B part is N,
=38, then D=0.48* mark is the minimum value that can actually sew part A.
1−(2):A −B各部をN+=10aとするとD=
026となり、上記1−(1)の例ではA−B各部間の
差があるのでバラツキが目立ち、上記1−(2)の例で
は次元りが1よりかなり小さくなるのて模様の糸の密着
度か低くなるか与直線部B部での面構成が良くないので
刺しゅうとしての出来栄えが悪くなる。1-(2): If each part of A-B is N+=10a, then D=
026, and in the example of 1-(1) above, there is a difference between each part of A and B, so the variation is noticeable, and in the example of 1-(2) above, the dimensionality is much smaller than 1, so the closeness of the threads of the pattern is The embroidery quality will be poor because the surface structure at the straight line part B will be poor, and the embroidery quality will be poor.
例2:第4〜6図に示す夫々異なる種類の基本構成によ
り縫う場合
2−(1) :第4図に示す基本構成ては仮にN+=
I Oa、n+−8n2/m= 1.2(図形からの計
算値)とすると、D=0.85となる。従ってD=1を
得るためにはN16.8 aとすれば得られる。Example 2: When sewing with different types of basic configurations shown in Figures 4 to 6 2-(1): For the basic configuration shown in Figure 4, suppose N+=
If I Oa, n+-8n2/m=1.2 (calculated value from the figure), then D=0.85. Therefore, in order to obtain D=1, it can be obtained by setting N16.8 a.
2−(2):第5図に示す基本構成では仮にNr−10
a、n+=6、nx/m= I 、 35(図形からの
計算値)とすると、D=079となる。従ってD−1を
得るにはN。2-(2): In the basic configuration shown in Figure 5, temporarily Nr-10
If a, n+=6, nx/m=I, 35 (value calculated from the figure), D=079. Therefore, N to get D-1.
5.7 aとすれば得られる。It can be obtained by setting 5.7 a.
2−(3) :第6図の基本構成では
仮にN、−5a、n、−4、a2/m=0.7(図形か
らの計算値)とすると、D=0.53となる。従ってD
=1にするにはN、= 1 。2-(3): In the basic configuration of FIG. 6, if N, -5a, n, -4, a2/m = 0.7 (value calculated from the figure), then D = 0.53. Therefore D
To make = 1, N, = 1.
9aとすれば得られる。It can be obtained by setting 9a.
第4〜6図に示す各基本構成は単泣構造であるが連続性
を有し、因みに第5図に示す基本構成の連続模様は第7
図に示す縫模様となる。第7図に示す数字1−18は針
の順序を示すものである。Although each of the basic configurations shown in Figures 4 to 6 has a single structure, it has continuity; by the way, the continuous pattern of the basic configuration shown in Figure 5 is the 7th one.
The sewing pattern will be as shown in the figure. Numbers 1-18 shown in FIG. 7 indicate the order of the needles.
以上により前記例2の各基本構成を利用して縫った刺し
ゅうは特にD=1とはるように式(3)の各部n1、m
2/m、N+/aに各数値を入れて縫った刺しゅうが前
記例1のジグザグ縫よりも縫目のバランスか保っている
ので安定感を与えるものである。As described above, the embroidery sewn using each basic configuration of Example 2 has D=1, so that each part n1, m of equation (3)
The embroidery that is sewn with each numerical value set for 2/m and N+/a maintains the balance of the stitches better than the zigzag stitch of Example 1, giving it a sense of stability.
