By the control program that stores in ROM302 and control data and by the signal that starts pedal 308 and guidance panel 309 inputs etc., CPU301 carries out the control of whole device and various data are handled.RAM303 is the device that the field operation as CPU301 is used for remembering, and is storing the stored contents of RON302 or the operation result of CPU301.
Startup pedal 308 passes through down, and the pressure handle operation signal makes electrical motor of sewing machine 310 actions like this to outputs such as CPU301.
Fig. 5 has shown an example of guidance panel 309.As shown in Figure 5, by operation, can set the mode of making of on sewing W, making clasp B to the selection key on the guidance panel 309 321.In addition, by operation, light corresponding to the mode LED322 of making to selection key 321.
In the present embodiment, can to the X-shaped of 4 hole clasps or side by side 3 kinds of modes of making of making mode and 2 hole clasps of shape etc. select.When selecting to make mode with guidance panel 309 operations, CPU301 is according to reading sewing program from the operation signal correspondence mode of making of guidance panel 309 from ROM302.According to this sewing program control electrical motor of sewing machine the 310, the 1st drive motors 151 and the 2nd drive motors 152, clasp B is made on sewing W in the selecteed mode of making.
And, selection key 323 be set final pin down formed knot and fixed cutting tool 230 between the button of distance L.In the present embodiment, this distance can be set " far ", " far away ", " generally ", " nearer ", " closely " 5 grades, corresponds respectively to these 5 grades and is provided with LED324.The selection that operation selection key 323 is carried out is converted, and lights corresponding to the distance L ED324 that sets.And the data of distance between portion that knots in each grade and the fixed cutting tool 230 are stored among the ROM302 as distance (data), and by the selection of selection key 323, CPU301 reads range data from ROM302.Control the 1st drive motors 151 and the 2nd drive motors 152 according to this range data, regulate center with respect to the clasp B of fixed cutting tool 230.And the distance between the portion that knots in each grade and the blade part 231 of fixed cutting tool 230 all is the same for which type of mode of making.
Present embodiment can further carry out the inching between each grade.That is,, revise corresponding to the range data that is stored in advance among the ROM302 by the inching button 325 of operating operation panel 309.The value L1 that revises by inching button 325 shows on display part 326.
And, operating operation panel 309 also has sets button 327 again, by can setting again the data that set according to mode selection key 321, apart from selection key 323 and inching button 325, and can be set in default value to the operation of setting button 327 again.
Below, to the order of making, describe with reference to the flow chart of Fig. 6 by the action of present embodiment single line ring button sewing machine.
Under the state that sets by setting button 328 (step S1),, just can set the default value that sets (step S2-S3) when dispatching from the factory for if by setting button 327 again.When by mode selection key 321 (step S4), select to set the mode (step S5) of making corresponding to the button hole of clasp B.And, when by apart from selection key 323 time (step S6), select to set final pin down formed knot and the blade part 231 of fixed cutting tool 230 between distance L (step S7).And, when because necessary during by inching button 325 (step S8), according to this setting to knot and the blade part 231 of fixed cutting tool 230 between distance L carry out that (L ± L1) revises (step S9).Various setting values are exported to CPU301.After setting like this, perhaps not according to setting button 328 time, if, just can start sewing program and make action (step S11) by not shown startup button (step S10).
Make in the action at this, by the control electrical motor of sewing machine, the 1st drive motors 151 and the 2nd drive motors 152, for making the following pin that mode is located to the hole of clasp B B1, B2 etc. by selected, cloth presser 110 moves on the X-Y direction, forms the single line circumferential weld system and final the knotting of pin down of regulation pin number.
In this sewing program, when the well-known eedle position detecting device 314 when the pin suture knots under final sends pin upper/lower positions signal, by the control of the 1st drive motors 151 and the 2nd drive motors 152 direction of rotation and the anglec of rotation being carried out the work feed of described distance L, and regulate clasp positions (step S12) with respect to fixed cutting tool 230.Then, drive unit 313 actions (step S13) make the movable cutting knife 220 of thread cutting device 200 begin to move.Ways 260 just captures suture Ta earlier before movable cutting knife 220 captures suture Ta like this, this is caught in suture Ta pulls to fixed cutting tool 230, make the blade part 221 and 231 interlocks of fixed cutting tool 230 blade parts of movable cutting knife 220 by being moved further of movable cutting knife 220, cut off suture Ta.
After this, drive unit 312 actions make knob assembly 112 risings (step S14).
The 1st feature of present embodiment is when the release that clasp B is made on sewing W, says closely, play movable cutting knife 220 actions from final pin down exactly during, clasp B moved with respect to fixed cutting tool 230 and regulate its position by transport 100.For example, in step S6, if be set at " closely ", because transport 100 makes clasp B near fixed cutting tool 230 after sewing finishing, so portion that knots when thread cutting action and the distance L between the fixed cutting tool 230 can be very little.Like this, the length of the residual suture Ta on the cut through wires hole B1 that is connected clasp B is just very short.So the outward appearance that knots is fine, can be applicable to the nail catcher of fashionable dress clothing class.
And, make the portion of knotting near fixed cutting tool during owing to pin under final, during movable cutting knife 220 moves, just can not grant tension force to suture Ta, even under the situation that does not have described ways 260, when pulling out suture Ta, the blade part 221 of movable cutting knife 220 also can prevent from only to cut off suture with movable cutting knife 220.So, can prevent the bad order of suture cut-out portion.
And, for example, when in step S6, being set at " far ", because transport 100 makes clasp away from fixed cutting tool 230 after sewing finishing, so the length of residual suture is just very long.If the residual line length behind the cut-out suture, knotting just is not easy to burst at the seams, and for example can be applicable to the nail catcher of the Work Clothes clothing class of not minding outward appearance.
As mentioned above, according to the mode of making, by regulating position with respect to the clasp B of fixed cutting tool 230, during the change tangent line from making the portion of knotting to the distance L the blade part 231 of fixed cutting tool 230.That is, according to the selected mode of making in step S4, reach selected distance L in order to make it in step S6, after sewing finishing, control device 300 drives transport 100.So, can change the residual wires length after suture cuts off arbitrarily.Like this, can make this to clasp by on the sewings corresponding to by the application target of sewings.
And, as above-mentioned embodiment, for change from the distance L the blade part 231 of making the fixed cutting tool 230 that knots to the moving of clasp, if carry out during till beginning when from final pin down the time, detecting the pin upper/lower positions to rise, just can shorten the production cycle to eedle.
