And the cut-out starting position that these are undertaken by central cutter or cut off end positions i.e. " central cutter action desired location " can show figure) 5 input sets picture (4), respectively with plus-minus button W11, the W12 setting of these screen displayed.

In addition, the action control unit 80 of fillet sewing machine 10 is moved control, (comprise that deviation is the situation that the deviation of 0 situation is less than or equal to setting) so that usually the time, use the short bevel tool 101,103 of shearing length, if deviation setting is greater than setting, then select the long bevel tool 102,104 (particular content aftermentioned) of shearing length automatically.And, become the root portion of angle joint-cutting in the outside and the end of straight line joint-cutting, make its unanimity (also have exceptionally according to setting stagger the situation of length of requirement) in principle.Therefore, utilize above-mentioned control, if select, then in that to become the end position of the root portion of the angle joint-cutting in the outside and straight line joint-cutting inconsistent to use during common bevel tool 101,103 sets as the operating position of the central cutter of prerequisite, to make than long usually bevel tool 102,104.

Therefore, the CPU 81 of action control unit 80, utilize the execution of setting input program, in the cut-out starting position of carrying out " setting of central cutter operating position " or after cutting off the setting of end position, carry out under the situation of setting of " make beginning departure " or " sewing finishing departure ", with reference to the value of these departures.And, its result, be less than or equal to cutting knife in departure and select under the situation of threshold value (in this fillet sewing machine 10, be 4[mm]) of relevant regulation, keep constant by the value of cut-out starting position in the plus-minus button W11 of the setting input picture (4) of Figure 15 or the EEPROM 71 that W12 sets or cut-out end position.

In addition, under the situation of value above the threshold value of the regulation relevant of departure with the cutting knife selection, proofread and correct for the cut-out starting position in the EEPROM 71 of plus-minus button W11 that imports picture (4) by the setting of Figure 15 or W12 setting or the value of cut-out end position, increase is from by long bevel tool 102, cut by common bevel tool 101 in the angle slot length on the 104 cloth directions of feed that obtain, the value of the angle slot length on the 103 cloth directions of feed that obtain (be 11-7=4[mm here]), the value of cut-out starting position after this correction or cut-out end position is stored among the EEPR0M 71.

Therefore, if after carrying out this correction, access the setting picture of " setting of central cutter operating position " once more, the setting that then replaces Figure 15 is imported picture (4) and the setting input picture (5) of demonstration Figure 16.Set in input picture (5) at this, for example in setting input picture (4), set 7[mm] situation under, can show the 11[mm after the correction] value, show the prompting of representing to have carried out overcorrect simultaneously.

In addition, in the cut-out starting position of " setting of central cutter operating position " or before cutting off the setting of end position, carry out under the situation of setting of " make beginning departure " or " sewing finishing position ", when carrying out the setting of " setting of central cutter operating position ", judge whether set departure surpasses threshold value, on this basis, if be less than or equal to threshold value, then show the setting input picture (4) of Figure 15, surpassing under the situation of threshold value, show the setting input picture (5) of Figure 16.In addition, under the situation of the setting input picture (4) that shows Figure 15, as the cut-out starting position of " setting of central cutter operating position " or the default value of cut-out end position, show and normally used bevel tool 101, the value that shearing length on 103 the cloth direction of feed equates (here be 7[mm]), under the situation of the setting input picture (5) that shows Figure 16, as the cut-out starting position of " setting of central cutter operating position " or the default value of cut-out end position, show and long bevel tool 102, the value that shearing length on 104 the cloth direction of feed equates (here be 11[mm]).

Except above-mentioned projects, set the shearing length on the cloth direction of feed of importing each bevel tool 101～104.And, in the present embodiment, shearing length on the cloth direction of feed of the short bevel tool 101,103 of each 100A of bevel tool mechanism, 100B is all unified to be identical length Ds (for example 7[mm]), is identical length D1 (for example 11[mm]) (with reference to Fig. 7) and the shearing length on the cloth direction of feed of the long bevel tool 102,104 of each 100A of bevel tool mechanism, 100B is all unified.

(the action control of filler rod)

Figure 17～Figure 19 is the flow chart of the action control of expression filler rod, and Figure 20～Figure 23 is the key diagram of the position relation of each 100A of bevel tool mechanism, 100B during expression angle joint-cutting forms.And, the configuration that diagram is observed from frontal in Figure 20～Figure 23, but for the making clear of corresponding relation, only filler rod cloth B and main cloth M are illustrated to overlook.

Processing shown in the above-mentioned flow process all is the processing of being carried out by CPU81 by the execution of operation control program.Below, the action control of filler rod is described.

At first, CPU 81 carries out read (the step S1) by the stitch data that shows input block 85 setting inputs.

Then, begin to make (step S2) according to stitch data.That is, big presser feet 21,21 moves to assigned position to placing descending by the main cloth M of the assigned position at rear and keep with respect to suture needle 41 on the workbench 11, and, if on big presser feet 21,21 mounting filler rod cloth B, then keep body 30 to keep from the top.Then, the invagination plate that is housed in each big presser feet 21,21 is mobile to keeping body 30 to advance each other, and thus, the both ends of filler rod cloth are folded into the upper surface side that keeps body 30.

Then, big presser feet 21 utilizes the driving of presser foot motor 23 and begins to advance mobile, will be transmitted to suture needle 41 by the cloth that main cloth M and filler rod cloth constitute.

Then, the driving of CPU 81 beginning machine spindle motor 45, according to the setting of " make and begin the bias direction switching ", carry out the action control that pin switches solenoid 43 simultaneously, so that two 41,41 whiles of suture needle or some suture needles that is set 41 begin to make.In addition, under the situation of having set " making the beginning departure ", after the feeding that is equivalent to this value, pin switches solenoid 43 carries out action control, so that second suture needle 41 also begins to make.

Then, CPU 81 is according to the setting of " setting of central cutter operating position ", carry out the action control that makes central cutter 51 begin to move up and down via electromagnetic valve 70, to begin the formation of straight line joint-cutting S at a distance of the position of setpoint distance at leading section with the stitching TL (or TR) that becomes the outside.And, as previously mentioned, because be less than or equal to setting 4[mm " make beginning departure "] situation under, for the bevel tool of the angle joint-cutting VFL (or VFR) that forms the outside, select shearing length short, and surpassing 4[mm] situation under, for the bevel tool that forms outside joint-cutting, select shearing length long, so, according to " setting of central cutter operating position " set corresponding to " making the beginning departure ", the cut-out of beginning straight line joint-cutting S.

And, said here " outside ", for the leading section of the scope of making, the front side in two stitchings that expression is formed by two suture needles 41,41, and, represent the rear side that two stitchings are interior for the rearward end of the scope of making.

In addition, CPU 81 reaches " sewing finishing departure " according to " L length setting ", " making the beginning bias direction switches ", carries out the action control that pin switches solenoid 43, finishes making of each stitching TL, TR, stops the driving of machine spindle 45.

In addition, CPU 81 is according to the setting of " setting of central cutter operating position ", carry out the action control that central cutter 51 is moved up and down stop via electromagnetic valve 70, finish the formation of straight line joint-cutting S with leading section at a distance of the position of the front side of setpoint distance from the stitching TL (or TR) that becomes the outside.And, as previously mentioned, because be less than or equal to setting 4[mm in " sewing finishing departure "] situation under, for the bevel tool of the angle joint-cutting VRL (or VRR) that forms the outside, select shearing length short, surpassing 4[mm] situation under, for the bevel tool of the angle joint-cutting VRL (or VRR) that forms the outside, select shearing length long, so, " setting of central cutter operating position " according to setting corresponding to " sewing finishing departure " stops the cut-out of straight line joint-cutting S.Thus, finish the formation of stitching TL, TR and straight line joint-cutting S.

In the forming process of stitching TL, TR and straight line joint-cutting S, CPU 81 makes the transposition portion of the 100A of bevel tool mechanism that does not move on the cloth direction of feed move to the centre position (step S3) of Y direction.And, the middle position in transposition portion, the shears 107a, the 109a that set the bevel tool 101,103 that makes the inboard are in the position that can engage with pressure cylinder carriage 133,134 respectively.

In addition, in the forming process of stitching TL, TR and straight line joint-cutting S, CPU 81 makes the transposition portion of the 100B of bevel tool mechanism that can move on the cloth direction of feed move to the middle position (step S4) of Y direction.

And, in the forming process of stitching TL, TR and straight line stitching S, CPU 81 control module travel motors 90 make the 100B of bevel tool mechanism move to the place ahead of cloth direction of feed with respect to the 100A of bevel tool mechanism, are sent to the position (step S5) that begins to form the angle joint-cutting most.

According to Figure 20, Figure 21 CPU as directed 81 is calculated the method for the displacement of the bevel tool 100B of mechanism here.Figure 20 represents just to finish the state of stitching after forming, and Figure 21 represents that the 100B of bevel tool mechanism moves to the state of the position that begins to form the angle joint-cutting most.

Each 100A of bevel tool mechanism, 100B all at first form inboard angle joint-cutting.Therefore, the displacement Y1 of the 100B of bevel tool mechanism among the above-mentioned steps S5 becomes the distance from the root portion of the medial angle joint-cutting of front end to the root portion of the medial angle joint-cutting of rear side.If making and making the beginning departure is CF, to make the sewing finishing departure be CR, make shearing length on the cloth direction of feed of bevel tool is D, make the scope total length of making is A, and then the displacement Y1 of the 100B of bevel tool mechanism can obtain according to following formula (1).

Y1＝A-CF-CR-2D ...(1)

In addition, be in the inboard filler rod (pocket openings is shaped as roughly cup-shaped situation), make scope A and equate (A=L) with the value of the L that in " L length setting ", sets in the rear and front end of straight line stitching portion.In addition, leading section at one straight line stitching is inboard, the rearward end of another straight line stitching is made scope A and is the length (A=L+CF or A=L+CR) after the value that adds a certain short deviation in " L length setting " on the L (than the length of making of long straight line stitching) that sets in the inboard filler rod (pocket openings is shaped as the tetragonal situation of almost parallel).Therefore, CPU 81 can try to achieve the value of A according to computing.

(step S6) finished in the formation of straight line joint-cutting S and stitching TL, TR if the position of each 100A of bevel tool mechanism, 100B is determined, then CPU 81 utilizes the driving of presser foot motor 23, and cloth B, M are sent to position shown in Figure 21 (off-position of the 100A of bevel tool mechanism) (step S7) from the position of Figure 20.

Then, CPU 81 judges whether in the rearward end side deviation (step S8) is set according to the setting of " sewing finishing departure ".

Be not provided with under the situation of deviation, CPU 81 reads in the setting value of " setting of sewing finishing bevel tool right side width ", drive the transposition portion motor 121 of the bevel tool 100A of mechanism, transposition portion 106 is set value the position correction (with reference to Figure 24) of size on Y direction, utilize electromagnetic valve 135 to drive the 1st pressure cylinder 131, bevel tool 101 is risen, form the right-hand corner joint-cutting (step S9) of rear side.

In addition, CPU 81 reads in the setting value of " sewing finishing bevel tool left side width is set ", drive the transposition portion 121 of the bevel tool 100A of mechanism, transposition portion 106 is set value the position correction of size on Y direction, utilize electromagnetic valve 135 to drive the 2nd pressure cylinder 132, bevel tool 103 is risen, form the left hand corner joint-cutting (step S10) of rear side.Then, entering step S14 handles.
