Abstract
The invention relates to a breadth splitting method, and especially relates to a breadth splitting method specially used for a computer-system-controlled embroidery machine. With the splitting method provided by the invention, a product can be split into sections suitable for a multi-head multi-needle embroidery machine with joint embroidery heads, such that whole-breadth embroidery of a pattern larger than a head span of a single head can be completed within a same time period. The breadth splitting method provided by the invention is a transverse splitting method aiming at an entire roll or entire breath of fabric. The method comprises the steps that: A, the breadth is split into y embroidery head set units; and B, each embroidery head set unit is split into x embroidery head piece units with not a same area.
Description
Technical field
The present invention relates to a kind of breadth method for splitting, particularly relate to a kind of breadth method for splitting being specifically designed to by the embroidery machine of computer system control.
Background technology
Traditional fractionation mode in the past, be by benchmark embroidered square by after utilizing optimum way to arrange, choose the not embroidered square embroidery in head intersection.So just caused the significant wastage of view picture fabric, according to statistics, its breadth utilization rate is only 55% left and right, and this also just means, destroyed, the waste of the fabric of half nearly.
Summary of the invention
The object of this invention is to provide a kind of method for splitting of breadth, thereby the benchmark embroidered square that can be used for embroidery in breadth is increased, thus the utilization rate of raising fabric.
Goal of the invention of the present invention is achieved in that described breadth method for splitting is for the horizontal method for splitting of entire volume or view picture fabric, comprises the following steps:
A. breadth is split as to y and embroiders head group unit,
B. each is embroidered to head group unit and be split as the incomplete identical embroidery head unit of x area;
Described steps A comprises the following steps:
A. whole breadth is split as to the embroidered square unit of several width homogeneous, and calculates the single embroidered square the longest lateral separation n in unit;
B. according to formula f(x)=the longest the lateral separation in head head distance * head number ÷ single embroidered square unit, obtain integer a and remainder q,
C. under more different head numbers, the value of corresponding remainder q, while getting minimum q, corresponding head number x
max;
D. by x
maxindividual head is embroidered a group, x now as one
max* n organizes cell width for embroidering head,
E. whole breadth lateral separation is split as to a y embroidery head group unit according to embroidering head group cell width;
Described step B comprises the following steps:
F. at each, embroider in head group unit, from each, embroider a head original position and make vertical boost line, altogether x
maxarticle-1,,
G. with each embroidered square unit as a whole, embroider the embroidered square unit that a head unit is pressed onto from the vertical boost line of this head, the embroidered square unit being pressed onto to the vertical boost line of next embroidery head finishes,
H. each is embroidered to head group unit and be split as the incomplete identical embroidery head unit of x area.
As a kind of improvement, in described step c, get other each q values close with minimum q value, and obtain corresponding head number x1, x2, x3, embroider head group unit y1, y2, y3, a y value is embroidered in comprehensive cloth waste q value and operation simultaneously, chooses suitable x value.
As another, improve, in described steps A, split y the embroidery head group cellar area obtaining incomplete same.
Compare with breadth being simply split as in conventional art to N the identical embroidery of area unit, the beneficial effect of method for splitting disclosed in this invention is apparent.First, broken through original fractionation mode, combining that several heads are formed embroidered head as a working cell, and according to the working range of combining embroidery head, breadth is split into several embroidery head group unit, thereby make those patterns larger than head span can be used as a whole embroidery unit, at one, combine in embroidery head and complete.Secondly, because those cannot use in splitting the part on rear border, will inevitably cause the waste of a part of raw material, so the present invention considers, to cut the waste be minimum q value, the quantity y value of combining embroidery head of simultaneously working, thereby obtain best x value, guaranteeing under the prerequisite of operating efficiency maximum saving raw materials for production.

The specific embodiment
As shown in Figure 1, the fan-shaped embroidered square unit that the transverse width of product breadth can be regarded as 20 width homogeneous each other not interval connect and compose, the longest distance of each embroidered square unit is fan-shaped width n.According to traditional fractionation mode, in thering is the embroidery machine of 12 heads, such product breadth has been divided into 11 groups, as shown in Figure 1.Owing to splitting the part on border at each, be split to respectively in the head of 2 independently workings, thus cannot embroidery in borderline pattern, must abandon.Like this, really can be according to the embroidered square unit of predefined track embroidery, every row only has 11, as shown in Figure 2.That is to say, according to traditional method for splitting, the utilization rate of raw material breadth is only 55%.In each time period, have 11 embroidered square unit embroidery simultaneously.
The improvement that we carry out this is to combine embroidery head using several heads as one, can be two couplings, can be also three couplings, the like, can be even 12 head couplings.But we consider operating efficiency, and breadth utilization rate, according to formula f(x)=the longest the lateral separation in head head distance * head number ÷ single embroidered square unit, obtain integer a and remainder q, and consider after q value and while working machine head number y value, adopted four heads to be one and combined the fractionation mode of embroidering head, i.e. fractionation mode during y=4, it splits boost line as shown in Figure 3.Can see, using four heads, after one is combined and embroiders head and split, the complete embroidered square unit a in one group is 7, only has a part of q5 seldom on boundary line, is rejected.So sector widths n*7 is embroidered to head group width as one, and this width is repeated in 12 heads, as shown in Figure 4, first combines the embroidery that embroidery head completes 7 embroidered square unit, and second combines the embroidery that embroidery head completes 7 embroidered square unit, and the 3rd combines the embroidery that embroidery completes 5 embroidered square unit, the embroidery head unit altogether completing is 19, the utilization rate of raw material breadth is 95%, and within each time period, has 4 embroidered square unit embroidery simultaneously.Thereby when guaranteeing operating efficiency, reduced greatly the waste of breadth, saved production cost.
Completed after above-mentioned fractionation, we further combine each the embroidery head group unit of embroidering in head and are split as the incomplete identical embroidery head unit of x area, do 3 boost lines, as shown in Figure 5, each embroiders 7 embroidered square unit in head group unit, first completes embroidery by the first head, second and the 3rd completes embroidery by the second head, the 4th and the 5th completes embroidery by the 3rd head, the 6th and the 7th completes embroidery by the 4th head, with each embroidered square unit as a whole, the embroidered square unit that an embroidery head unit is pressed onto from the vertical boost line of this head, the embroidered square unit being pressed onto to the vertical boost line of next embroidery head finishes, each is embroidered to head group unit and be split as the incomplete identical embroidery head unit of four areas, each final head work allocation schematic diagram as shown in Figure 6.
