In step S33, CPU71 controls X-axis, Y- axis motor 52,53, the feeding platform 51 of origin position is moved to and make starting position.
Then, CPU71 drives sewing machine electromotor 17, starts Buttonhole and makes (step S34).CPU71 reads in and makes " the X amount of feeding ", " the Y amount of feeding ", " revolution amount " (with reference to the Figure 12) set in trace data for each pin, carry out the control to X-axis motor 52, Y-axis motor 53, slewing motor 24, each position of for example, for round-nose button hole lock seaming, making (or the tack Buttonhole is made) forms stitching successively.
If making of making based on the above-mentioned Buttonhole of making whole pin numbers of trace data moved, CPU71 makes feeding platform 51(X axle motor 52 and Y-axis motor 53) return to origin position after (step S35), drive not shown various tangent mechanisms, reached the standard grade, roll off the production line and the tangent line (step S36) of heart yearn.
Then, CPU71 judges whether to record rear cutting knife data (step S37), in unwritten situation, jumps to step S39, in the situation that record is arranged, jumps to step S38.
In step S38, CPU71 moves up and down cloth cutting knife 19, carries out perforate on cloth.
Then, CPU71 rises cloth pressing 54, removes press (the step S39) to cloth, makes needle bar revolving platform 13 and looper device pedestal 61(slewing motor 24) return to origin position after (step S40), make to process and return to step S28.That is, become and press presser feet switch holding state before in order to carry out making of back.
(the processing of control module: the generation of making trace data)
Below, illustrate that the generation of making trace data of making (or the tack Buttonhole is made) for carrying out round-nose button hole lock seaming of carrying out processes in control device 70.
If carry out the setting input of the tailoring pattern data of Fig. 4, CPU71 generates and makes trace data.Figure 10 means the guide look of each mechanical parameter of buttonholing machine 1, and Figure 11 means the guide look of an example of setting of the various parameters of Fig. 4.In addition, Figure 12 is by the various parameters of the tailoring pattern data based on setting according to Figure 11 and the key diagram that the data content of making trace data of generation means with the list form in control device 70.
In making trace data, " suture needle position " is illustrated in and carries out the pin that falls that pin, outer pin in each in the situation of (or the tack Buttonhole is made) are made in a round-nose button hole lock seaming, and the pin number is that interior pin, this pin that falls for twice of outer pin are counted as to 1 pin." position " means that the round-nose button hole lock seaming under each pin number makes each position in (or the tack Buttonhole is made).
" X coordinate ", " Y coordinate " mean the target location coordinate in the X-Y coordinate system of feeding platform 51 of each suture needle position." X coordinate ", " the Y coordinate " of every pin are to calculate according to the setting value of Fig. 9.
" rotary position " means the accumulative total angle of revolution started from initial point that the revolution by each pin of needle bar 12 causes.
The directions X of the cloth feeding mechanism 50 that " the X amount of feeding ", " the Y amount of feeding " expression starts from current suture needle position and the amount of movement of Y-direction.
" revolution amount " means the revolution actuating quantity started from current angle of revolution.
In addition, this buttonholing machine 1 is the different arc sections that produce 101 of retractility or 101A and the round end casing-joining part 108 place's irregularities with vertical stitching direction for fear of the horizontal stitching direction due to cloth, and in guidance panel 75, outside parallel portion pin amplitude of oscillation ww, can also set the value of round end front needle amplitude of oscillation we or round end noose pin amplitude of oscillation wc.
Current, at arc sections 101(or 101A) and round end casing-joining part 108 in, even swinging stitching at pin carries out in rotating situation, the width that also pin is swung to stitching is set as equal the width (=width identical with the pin swing stitching of parallel portion 105,106) in gamut, forms pin according to setting value and swings stitching.
On the other hand, in buttonholing machine 1, at arc sections 101(or 101A) and starting point and the destination county of round end casing-joining part 108, form pin with the width identical with parallel portion 105,106 (parallel portion pin amplitude of oscillation ww) and swing stitching, but at arc sections 101(or 101A) and the position on the summit of round end casing-joining part 108, form pin according to the round end front needle amplitude of oscillation we of other setting or round end noose pin amplitude of oscillation wc and swing stitching.
In addition, from starting point to summit, along with revolution is carried out, from parallel portion pin amplitude of oscillation ww to round end front needle amplitude of oscillation we or round end noose pin amplitude of oscillation wc gradually change and form pin and swing stitching, from summit to terminal, along with revolution is carried out, from round end front needle amplitude of oscillation we or round end noose pin amplitude of oscillation wc, to parallel portion pin amplitude of oscillation ww, gradually change and form pin swing stitching.
Thus, control device 70 as mentioned above, generates the following trace data of making, and, forms arc sections 101(or 101A that is) and round end casing-joining part 108.
According to the flow chart of Figure 13, generation processing that this makes trace data is described.

In addition, when carrying out round-nose button hole lock seaming and make, to using following situation as prerequisite,, slewing motor 24 is only in the situation that interior pin → outer pin revolution driving, in the situation of pin → interior pin, do not moved outside (in the tailoring pattern data of Figure 12, " the revolution amount " of outer pin is set as 0 all the time).
At first, calculate X position, Y position, the rotary position (step S61) of interior pin according to the tailoring pattern data shown in Fig. 4.Because interior pin is the point on the track consisted of known figure, therefore can easily according to the tailoring pattern data, obtain, therefore, for its computational methods, description thereof is omitted.

Then, calculate the X amount of feeding, the Y amount of feeding, the revolution amount (step S65) of the n pin of right parallel portion and round end right lower quadrant (being only right parallel portion in the situation that the tack Buttonhole is made).
Here, if hypothesis (Xin, Yin), (Xin+1, Yin+1), (Xon, Yon) there is the position relationship shown in Figure 14, pin (Xin, Yin) → outer pin (Xon in forming, when pin Yon) swings stitching, need to make cloth move illustrated M1+M2, pin (Xon, Yon) → interior pin (Xin+1 outside forming, when pin Yin+1) swings stitching, need to make to return after move-M2 of cloth.Here, M2 swings the amount of movement of the width of stitching for proofreading and correct the pin produced by relatively moving of cloth feeding mechanism 50 for the upper fixing pin swing width W of design.
The X amount of feeding of interior pin (Xin, Yin) → outer pin (Xon, Yon), the Y amount of feeding, revolution amount (DXion, DYion, DRion) are shown below.

In addition, also can preliminary election prepare and the form coefficient that 0～1 between gradually change corresponding with the variation of the value of Rn, add that in DP (DE-DP) is multiplied by coefficient and the value that obtains, with the variation of the value of Rn reference coefficient accordingly.
Then, pin is counted to carry out+1(of index n step S73).
And the processing of repeating step S71, S73, reach until pin is counted index n the round end front needle number (step S75) set.
Then, calculate the X amount of feeding, the Y amount of feeding, the revolution amount (step S77) of the n pin of left parallel portion and round end lower left quarter (being only left parallel portion in the situation that the tack Buttonhole is made).
(DXion,DYion,DRion)
=(Xin+1-Xin+(DP-W)*cos(Rn+1),Yin+1-Yin+(DP-W)*sin(Rn+1),Rn+1-Rn)…(10)
(DXoin,DYoin,DRoin)=(-(DP-W)*cos(Rn+1),-(DP-W)*sin(Rn+1),0)…(11)
Wherein, due to Rn+1=180 °, therefore, become
(DXion,DYion,DRion)=(Xin+1-Xin-(DP-W),Yin+1-Yin,0)…(12)
(DXoin,DYoin,DRoin)=((DP-W),0,0)…(13)
Then, pin is counted to carry out+1(of index n step S79).
And the processing of repeating step S77, S79, reach until pin is counted index n the parallel pin number (step S81) set.

(effect of embodiment)
Above-mentioned buttonholing machine 1 can be set the parallel portion pin amplitude of oscillation, the round end front needle amplitude of oscillation and the round end noose pin amplitude of oscillation individually from guidance panel 75.
And, control device 70 is at the arc sections 101(or the 101A that form as rotating part) and during the stitching of round end casing-joining part 108, the variation of the angle of revolution direction swung with the pin with being produced by slewing motor 24 accordingly, input value based on guidance panel 75, at the arc sections 101(parallel with directions X or 101A) and the pin of round end casing-joining part 108 swing the width (pin of starting point and terminal swings the width of stitching=parallel portion pin amplitude of oscillation ww) of stitching, and the arc sections 101(parallel with Y-direction or 101A) and the pin of round end casing-joining part 108 swing between the width (pin on summit swings the width of stitching=round end front needle amplitude of oscillation we or round end noose pin amplitude of oscillation wc) of stitching, the mode that the width that makes pin swing stitching gradually changes, trace data is made in generation.
In addition, control device 70 is as working based on the above-mentioned stitching width correction control part of making trace data and controlling cloth feeding mechanism 50.
Therefore, horizontal stitching at cloth is different with the expansion and contraction of vertical stitching, in the situation that swing on the direction of the parallel direction of stitching or quadrature and easily shrink with the pin of parallel portion 105,106, by parallel portion pin amplitude of oscillation ww and round end front needle amplitude of oscillation we(or round end noose pin amplitude of oscillation wc) value that is set as the pin amplitude of oscillation parallel with the direction of easy contraction is larger.
Thus, can consider the character of cloth, with amount of contraction, to increase accordingly the width of pin swing stitching, form arc sections 101(or 101A) or round end casing-joining part 108.In addition, in the case, although swing at the pin with parallel portion 105,106 on the direction of the parallel direction of stitching and quadrature, arc sections 101(or 101A) or the pin of round end casing-joining part 108 swing the setting value difference of the width of stitching, but owing to gradually changing accordingly with angle of revolution, therefore, can not swing the width generation difference of stitching at certain a part of pin, can form arc sections 101(or the 101A of symmetry excellence) or round end casing-joining part 108.
(other)
In addition, in above-mentioned buttonholing machine 1, can set separately round end front needle amplitude of oscillation we and round end noose pin amplitude of oscillation wc from guidance panel 75, but swing the direction of stitching when consistent at their pin, also can set shared value.
In the case, if the directions X pin amplitude of oscillation is made as to DX, the Y-direction pin amplitude of oscillation is made as to DY, the formula converted gradually as the pin amplitude of oscillation that makes to be produced by angle of revolution, take if be made as the formula H (Zn) that angle of revolution is parameter, as follows.
(DXion,DYion,DRion)

(DXoin,DYoin,DRoin)
=(-H(Rn)*cos(Rn+1),-H(Rn)*sin(Rn+1),0)…(20)
In the case, H (Rn) is as an and example of function DX and DY between smooth variation corresponding with the revolution amount, for example preferred ellipse formula.
H(Rn)=DX*DY/(DY2*cos2(Rn)+DX2*sin2(Rn))1/2-W…(21)
In addition, as other function, also can be approximated to be
H(Rn)=(DY-DX)*sin2(Rn)+DX-W…(22)
Or H (Rn)=(DY-DX) * | sin (Rn) |+DX-W ... (23)
In addition, in buttonholing machine 1, as cloth feeding mechanism, carry out the X-Y driving, but also can be made as by the structure that for example driving of R-θ system is moved cloth on horizontal plane.
In the case, be transformed to the displacement of the R moved for the position inferior to same pin and the angle variable quantity of θ by the X amount of feeding and the Y amount of feeding that will make trace data, thereby can realize the identical action of making.
In addition, the pin amplitude of oscillation that the suture needle reciprocating mechanism of buttonholing machine 1 forms becomes fixed value on mechanism design.But, be not limited to this structure, for example, also can utilize the motor that arranges independently with sewing machine electromotor 17 (but for example as actuator of the control action amount of pulse motor), the change pin swings arbitrarily, carries this actuator and pin swing mechanism on needle bar revolving platform 13, under the control of control device 70, turn round on one side and the pin swing, can at random change the control pin amplitude of oscillation on one side.
In the case, owing to can not need in cloth feeding mechanism 50 sides, carrying out swinging for changing pin the action of the width of stitching, so can make to control, oversimplify.
In addition, in guidance panel 75, set individually the width that pin that parallel portion pin amplitude of oscillation ww(and the pin of parallel portion swing the described rotating part on the parallel angle of revolution direction of stitching swings stitching) and the pin of round end front needle amplitude of oscillation we and round end noose pin amplitude of oscillation wc(and described parallel portion swing the width of the pin swing stitching of the described rotating part on the angle of revolution direction of stitching quadrature), but be not limited thereto.
For example, also can be in guidance panel 75, input parallel portion pin amplitude of oscillation ww, do not input round end front needle amplitude of oscillation we and round end noose pin amplitude of oscillation wc, and input round end front needle amplitude of oscillation we or round end noose pin amplitude of oscillation wc are with respect to the difference of parallel portion pin amplitude of oscillation ww.
In addition, also can be in the same manner in guidance panel 75, input parallel portion pin amplitude of oscillation ww, do not input round end front needle amplitude of oscillation we and round end noose pin amplitude of oscillation wc, and input round end front needle amplitude of oscillation we or round end noose pin amplitude of oscillation wc are with respect to the ratio of parallel portion pin amplitude of oscillation ww.
