Again, in RAM38, be provided with various working storage and buffer etc., for example, deposit the round end keyhole seam data storage 38a of the stitching data of the round end keyhole stitch seam 50 that has made, the noose of depositing the stitching data of noose reinforcing portion 54 is reinforced seam data storage 38b (with reference to Fig. 3) etc.In addition, as described later, in the working storage of this RAM38, also depositing the numerical value of the performance data of setting by the user etc.
As shown in Figure 3, described guidance panel 23 is provided with the various enter key 23a that the multifrequency nature data of the input round end keyhole stitch seam 50 of relevant Fig. 9 and noose reinforcing portion 54 use and the display 23b of content that shows selecteed performance data and numerical value thereof etc.As enter key 23a, be provided with and on the numerical value that the numerical value of projects input is used, roll up strong and numerical value last volume key etc. setting options button, the change of changing and make indication usefulness successively with multifrequency nature data value corresponding.This guidance panel 23 has the function of the input unit of using as input setting performance data described later.
Following elder generation makes an explanation to round end keyhole stitch seam 50.As shown in Figure 9, round end keyhole stitch seam 50 comprises: in the round end eyelet 51, be formed at the round end eyes 52 around 51 ones of the round end eyelets; Respectively with these round end eye 52 line parts 53 continuous, that be positioned at the roughly linearity of the pairing left and right about straight hole portion; And the noose reinforcing portion 54 that extends to form with described line part 53 reverse side ends, with these line part 53 cross-like that is positioned at this line part 53.This noose reinforcing portion 54 be basically along with the direction of line part 53 bearing of trends (Y direction) quadrature promptly, directions X extends (parallel shape) and forms.
When making this round end keyhole stitch seam 50, for example make continuously according to the order of the line part 53 in the line part 53 on right side (among the figure from bottom to top), round end eye 52 (counter clockwise direction among the figure), left side (among the figure from the top down), noose reinforcing portion 54 (among the figure from left to right).At this moment, also as shown in Figure 5, for the line part 53 on right side, the left side is interior pin, and the right side is outer pin, and for the line part 53 in left side, with its left-right symmetry, the right side is interior pin, and the left side is outer pin, and for round end eye 52, interior all sides are interior pin, and outer circumferential side is outer pin.For noose reinforcing portion 54, line part 53 sides (upside among the figure) are interior pin, and a side of separating with line part 53 (downside among the figure) is outer pin.Counted as 1 pin at 2 positions of pin and outer pin in suture needle 3 fell into.
As shown in Figure 5, when making line part 53 and round end eye 52, suture needle 3 is according to＜1 〉, (1),＜2, (2) ...,＜17 〉, (17),＜18 order and fall.In this Fig. 5, with＜the interior pin of expression, with the outer pin of () expression.For convenience's sake, dot the stitching that forms from the outside pin of interior pin, represent the stitching that forms from the inside pin of outer pin with solid line.As Fig. 9 and shown in Figure 10, when making noose reinforcing portion 54, suture needle 3 according to an a, b, c, d ..., u, E order and fall.
For line part 53, during pin, suture needle 3 relatively moves along directions X according to the stitching data, processes cloth (cloth pushing table 13) simultaneously and can only send stitching spacing Ps to along the Y direction outside interior pin arrives.In outer pin arrives during pin, suture needle 3 can only be along the directions X suture needle amplitude of fluctuation Ws that relatively moves.Thus, with respect to the location coordinate of outer pin, the location coordinate of following 1 interior pin is in the position that equates with Building Y mark, Ws is swung in the suture needle of only staggering on the directions X.In addition, specifically, relatively moving of the directions X of suture needle 3 can only make suture needle 3 itself swing suture needle amplitude of fluctuation L (value that mechanical structure determined), and as required, can realize by making feeding table 13 mobile suture needle amplitude of fluctuation revisal W on directions X.Therefore, suture needle amplitude of fluctuation Ws=L+W.
Again, in the semicircular part timesharing of making round end eye 52 first halves, per 1 pin of processing cloth (feeding table 13) moves on the XY direction, by θ direction drive motor 26 shank 4 and curved needle seat 6 is swung at every turn along the counter clockwise direction of seeing from above with certain angle of oscillation T simultaneously.As whole round end eye 51, shank 4 and curved needle seat 6 carry out 180 degree counter-rotatings.For the Lower Half of round end eye 51, can only make by X, moving of Y direction.At the line part 53 that keeps making under the 180 degree inverted status of shank 4 and curved needle seat 6 left side.
For noose reinforcing portion 54, be to make under the 90 degree turn states (returning the state of 90 degree from 180 degree inverted status to clockwise direction) at shank 4 and curved needle seat 6, the pin swaying direction of shank 4 is fore-and-aft direction (a Y direction).In detail as described later, for this noose reinforcing portion 54, processing cloth (feeding table 13) per 1 pin (from interior pin to outer pin time) can only be sent processing cloth (feeding table 13) to spacing P along directions X, and the while is (revisal amount described later) as required, makes by feeding table 13 is moved along the Y direction.
In the present embodiment, as described later shown in the Action Specification, when control device 35 makes the stitching data (computing of needle downing position) of round end keyhole stitch seam 50, used performance data shown in Figure 4, but this performance data is at random to import setting (to the change of initial value) by user's operating operation panel 23.At this moment, the correction for inclined data that revisal uses (straight line noose correction for inclined BA: performance data number 24) are carried out in the inclination of relative directions X that is comprising the sewing direction of noose reinforcing portion 54 in this performance data.
Specifically, straight line noose correction for inclined BA is by specifying a certain grade in-3～3 to import setting as the degree (grade) (with reference to Figure 10) of the revisal amount of the Y direction on the end side of noose reinforcing portion 54.In addition, grade 0 is (initial value) parallel with directions X, from the numeral 0 the beginning far away from plus or minus, then respectively in figure above or below gradient φ big more.Straight line noose correction for inclined BA can numerical value (for example mm) mode import setting or import setting with angular way.
Again, as shown in Figure 4, as the relevant performance data that makes the stitching data of noose reinforcing portion 54, also have straight line noose length D (performance data number 03), straight line noose pin to count n (performance data number 04), straight line noose amplitude revisal BW (performance data number 18), straight line noose lap G (performance data number 19), straight line noose X position revisal XA (performance data number 23) in addition, these also can at random import setting by the operation of guidance panel 23.
Omitted detailed explanation for each performance data, but the performance data of using as the stitching data that make round end eye 52 and line part 53, have the shape revisal, suture needle amplitude of fluctuation revisal W of reinforcing suture needle number that X, the revisal of Y position, sewing beginning and the sewing of seam speed (winding number of main shaft 5), round end eyelet shape (one of 8 kinds of styles), stitch length, stitching spacing Ps, round end eye pin number, cutting knife gap, cutting knife finish, round end eye 52 etc., these also can at random import setting by the operation of guidance panel 23.
The program that the round end keyhole that the band noose that control device 35 by round end button holing sewing machine N is carried out below with reference to the flow chart of Fig. 6, Fig. 8 etc. is reinforced seam is made control describes.Fig. 6 represents that the round end keyhole makes the main program of control, and Fig. 8 represents that the stitching data of noose reinforcing portion wherein make the detailed procedure of processing (the step S11 of Fig. 6).Again, the symbol Si (i=11,12,13 among the figure ...) be exactly each step level.
Before the round end keyhole seam of reinforcing seam with noose, as mentioned above, import the numerical value of multiple related characteristics data shown in Figure 4 earlier respectively by the enter key 23a of user's operating operation panel 23.Secondly, the numerical value of setting respectively in these performance datas is stored in respectively in the working storage of RAM38.At this moment, the user obtains gradient earlier according to the kind etc. of the sewing of processing cloth, this gradient is at forming the occasion that the noose reinforcing portion tilts, for example stitch the suitable gradient of obtaining for the directions X of noose reinforcing portion by examination in advance, input configures the value of straight line noose correction for inclined BA.
As shown in Figure 6, at first carry out round end keyhole stitch seam data and make processing (S10).When this makes processing, from the performance data of Fig. 4, according to the multifrequency nature data of round end eyelet shape (performance data of Fig. 4 number 03), stitch length (performance data number 02), round end eye pin number (performance data number 06) etc. make round end eye 52 and about line part 53 make the stitching data of usefulness.Promptly, as shown in Figure 7, for example when all pin numbers of round end eye 52 and left and right sides line part 53 are 17 pins, each pin number for 17 pins, in order to determine outer needle downing position at interior pin, directions X drive motors 30, Y direction drive motor 32 and θ direction drive motor 26 number of drive pulses are separately set, these stitching data are left among the round end keyhole seam data storage 38a of RAM38.
Wherein, as Fig. 5, shown in Figure 7, the 1st pin 1N in 17 pins～the 5th pin 5N is the stitching data of the bound edge seam usefulness of right side line part 53a, the 6th pin 6N～the 13rd pin 13N is the stitching data of the bound edge seam usefulness of round end eye 52, and the 14th pin 14N～the 17th pin 17N is the stitching data of the bound edge seam usefulness of left side line part 53b.In this example, suture needle amplitude of fluctuation revisal W is 0, and suture needle amplitude of fluctuation Ws is original L.
In addition, shown in Fig. 5, Fig. 9, Figure 10 etc., Building X mark, the Building Y mark of round end keyhole stitch seam 50 (needle downing position on the processing cloth) are that the right in the directions X is decided to be "+" side, with the place ahead in the Y direction to being decided to be "+" side, but please note: because the feeding direction of feeding table 13 is that directions X, Y direction are all opposite with it (for example when needle downing position moves right, feeding table 13 is moved to the left), therefore, when data shown in Figure 7 are just when (+), feeding table 13 left or the rear move, when negative (-), feeding table 13 to the right or the place ahead move.
Then, make noose reinforcing portion 54 usefulness noose reinforced suture mark data make processing (S11).When these noose reinforced suture mark data make processing, according to straight line noose length D (the performance data numbering 3 of Fig. 4), straight line noose pin is counted n (performance data numbering 4), straight line noose amplitude revisal BW (performance data number 18), straight line noose lap G (performance data number 19), suture needle amplitude of fluctuation revisal W (performance data number 22), straight line noose X position revisal XA (performance data number 23), the 7 specific character data of straight line noose correction for inclined BA (performance data number 24) are figured after the Building X mark of out pin and interior pin and Building Y mark with each interior pin for the n pin, respectively to directions X drive motors 30, Y direction drive motor 32, the driving pulse of θ direction drive motor 26 carries out computing.
Wherein, as shown in figure 10, the center line that will extend along the Y direction of round end eyelet 51 is decided to be origin of coordinate 0 with the intersection point of the straight line that extends from the outer pin a of the 1st pin of straight line noose reinforcing portion 54 along directions X.If the amplitude of straight line noose reinforcing portion is decided to be F, then this origin of coordinate 0 is exactly interior pin＜18 from the 18th pin of round end keyhole stitch seam 50〉only left the locational point of (F-G) along the Y direction.F=L+W+BW promptly.
In addition, suture needle amplitude of fluctuation revisal W and straight line noose amplitude revisal BW set for the round end keyhole stitch seam 50 of making the amplitude different with suture needle amplitude of fluctuation L and straight line noose reinforcing portion 54, when being set with these suture needle amplitudes of fluctuation revisal W and straight line noose amplitude revisal BW, in the suture needle yaw, drive feeding table 13 and drive BW and W along directions X and Y direction by directions X drive motors 30 and Y direction drive motor 32, the amplitude of round end keyhole stitch seam 50 and straight line noose reinforcing portion 54 can be adjusted to fixed amplitude.
Describe the processing that makes of noose reinforced suture mark data in detail below with reference to the flow chart of Fig. 8.As shown in Figure 8, the initial value with needle gage k is decided to be 1 (S20).Obtain the outer pin of k=1～n needle tracking and Building X mark, the Building Y mark of interior pin by S20～S25, the outer pin in the k needle tracking among Figure 10 and the Building X of interior pin mark Xko, Xki become:
Xko＝-D/2+XA+P×(k-1)
Xki＝-D/2+XA+P×(k-1)(S21)。
Wherein, P is that the spacing P of straight line noose reinforcing portion 54 is, P=D/ (n-1).
Secondly, the outer pin in the k needle tracking and the Building Y of interior pin mark Yko, Yki become: Yko=0, Xki=F (S21).But, if only so set the Building Y mark, then in practice, cause acts on the disorder of sewing etc. when making, tend to shown in the double dot dash line L0 of Figure 10, cause that the sewing direction of straight line noose reinforcing portion 54 is at a slight tilt from directions X (chain-dotted line of Figure 10), have influence on the aesthetic appearance of straight line noose reinforcing portion sometimes.

In case obtain Building X mark, the Building Y mark of outer pin in the k needle tracking and interior pin, then the value of a k increment 1 (S24) carries out the processing from step 21 repeatedly, only be designated as until Building X mark, the Building Y of obtaining outer pin and interior pin in the n needle tracking respectively.Like this, in case obtain Building X No. 1 needle tracking to the n needle tracking, outer pin and interior pin mark, Building Y mark, then from these coordinate system certificate, the number of drive pulses of directions X drive motors 30, Y direction drive motor 32 and θ direction drive motor 26 is carried out computing (S26).Make the stitching data that data are, noose is reinforced seam of these number of drive pulses, leave noose in and reinforce among the seam data storage 38b.
Return Fig. 6 again, operation start shutdown switch 20, the making when handling of round end keyhole seam that begins to reinforce with noose seam, at first according to the stitching data of the round end keyhole stitch seam seam that makes, that carries out round end keyhole seam makes processing (S12).That is, at first as shown in Figure 5,, right side line part 53a, round end eye 52 and left side line part 53b are made continuously by from the handling the needle of No. 17 needle tracking 17N of No. 1 needle tracking 1N to the.
Then, make processing (S13) according to what noose reinforced suture mark data were carried out straight line noose reinforcing portion 54.Promptly, at first make shank 4 and curved needle seat 6 wobble drive 90 degree by θ direction drive motor 26, reinforce the stitching data of seam data storage 38b then according to noose, outer pin a from the 1st needle tracking swings shank 4 in the Y direction on one side, feeding table 13 is moved to left, carry out making of straight line noose reinforcing portion 54 with this, after the end noose is reinforced seam, be back to main program.Promptly, as shown in figure 10, stitching data according to 1 needle tracking, interior pin＜18 from the 18 final needle trackings of round end keyhole stitch seam 50〉begin to sew outer pin a and the interior pin b thereof that noose is reinforced 1 needle tracking of seam usefulness, then, each stitching data later according to 2 needle trackings, each needle tracking from 2 needle trackings to the n needle tracking sew successively c, d, e ..., t, u, until terminal point E, straight line noose reinforcing portion 54 nooses of the performance data that will set according to input reinforce make with the end of the heel portion 53 of round end eye 52 opposition sides.
Adopt the round end button holing sewing machine M of above explanation, since the performance data of relevant straight line noose reinforcing portion 54 comprised correction for inclined data that the correction for inclined of the relative directions X of sewing direction of straight line noose reinforcing portion 54 uses promptly, straight line noose correction for inclined BA, therefore, when making straight line noose reinforcing portion 54, can carry out revisal to the inclination of the relative directions X of sewing direction of straight line noose reinforcing portion 54 according to this straight line noose correction for inclined BA, straight line noose reinforcing portion 54 relative directions X parallel shapes are formed, can improve the aesthetic appearance of straight line noose reinforcing portion 54.
Below the modification that has increased various changes in the foregoing description is described.
1] the present invention is not only applicable to round end keyhole seam, and is applicable to the button holing sewing machine of the line part 62 shown in Figure 11, that can sew the left and right sides that comprises the buttonhole (not shown) that is positioned at linearity and the keyhole stitch seam 60 of the noose reinforcing portion 61 that is positioned at these line part 62 two ends.Both can be shank moving (swing), the structure that moves of feeding table simultaneously on the Y direction on the directions X with this button holing sewing machine, also can be not have the structure that makes the swing mechanism that shank swings.That is, also the same even in the occasion of making noose reinforcing portion 61 with the occasion of making line part 62, Yi Bian suture needle is moved on directions X, make feeding table mobile on the Y direction on one side, can sew noose reinforcing portion 61 with buttonhole 62 quadratures of line part linearity.Again, the present invention is also applicable to the button holing sewing machine with shuttle structure that making reaches the standard grade and roll off the production line intersects usefulness, to replace the looper 6a of the foregoing description.
