Then, under the state that the threading picture is represented, detect the input (step S9) that has or not threading end switch W4, under the situation that does not have input, turn back to the processing of step S5, detect the input that wireless maintained switch W3 is arranged once more.
In addition, when carrying out the input of threading end switch W4, transfer to the processing of step S10.
In step S10, CPU81 carries out the demonstration of making picture of Fig. 6 by the predetermined process program.
Then, make the formation of each one that in described threading is handled, moves turn back to the action control (step S11) of original position.That is, eedle 11 is kept out of the way the top, and button maintaining body 13 advances mobile, and cloth maintaining body 22 rises, and guard for eyes turns back to the position of the front side that covers eedle 11.
In addition, making under the state that picture represents, becoming and be used for being undertaken setting buttons and on needle plate 12, setting wait the activity duration (the step S12) of cloth to button maintaining body 13 by operating personnel.
And then CPU81 handling procedure according to the rules detects the input (step S13) that has or not stitch mode switch W1.That is, if the input of this stitch mode switch W1 is arranged, the setting that then is judged as the button that undertaken by operating personnel and cloth finishes, and transfers to step S14, carries out the demonstration (step S14) of stitch mode display frame (Fig. 6).And CPU81 drives compress cylinder body 23 by electromagnetic valve 88, carries out the action that cloth maintaining body 22 is descended and controls and drive button Z axle motor, button maintaining body 13 is adjusted to the action control of the height that is fit to make.
In addition, (step S13: not), then turn back to the processing of step S2, detect the input that has or not feed-through switch W2 once more when not having the input of stitch mode switch W1.
On the other hand, under the show state of stitch mode display frame, if detect the input of starter pedal 89, then CPU81 makes processing by utilizing the predetermined process program to carry out, and plays as the effect (step S16) of making the action controlling organization.Thus, starter pedal 89 is worked as making the instruction input mechanism.
So-calledly make processing, be meant by the action of handling the needle of the synergy of knee-action mechanism and detent mechanism, utilize movable cutting knife to carry out the cut-out action of suture after handling the needle, then, carry out by suture holding device 70 and carry out a series of processing of making action that suture keeps action.
Be specially, the driving of beginning motor of sewing machine 21, before carrying out the continuous in turn pin that falls, read stitch data, before the pin that falls by the rotation of motor of sewing machine 21, according to the represented position coordinates of data, drive button X-axis motor 31 and button Y-axis motor 32, carry out location with respect to the button of eedle 11, and, drive balancing point motor 35 and cloth Y-axis motor 34 according to position coordinates, carry out the location of cloth with respect to eedle 11.
In addition, when described handling the needle, each needle-thread tensioning control device 64,65, carry out each solenoidal energising control in the mode that produces the line tension that stitch data sets, each Unwinding line apparatus 62,63 carries out each solenoidal energising control in the mode of carrying out the Unwinding line with synchronous stipulated time of the rotation of motor of sewing machine 21.
And, the button by making needed pin number part and the location of cloth, and meanwhile carry out the pin that falls of eedle 11, if the sewing finishing of button, then needle plate 12 drive tangent line cylinder bodies 26 below by electromagnetic valve 88, carry out the cut-out of suture.
And then, with the driving of tangent line cylinder body 26 almost simultaneously, come drive wire to keep cylinder body 72 by electromagnetic valve 88, make line catch the action control that parts 71 advance and retreat.Thus, suture is furthered, and is pulled to line and catches between parts 71 and the leaf spring 73, carries out line for making next time and keeps.
In addition, the line of this moment keeps, owing to almost carry out simultaneously with the cut-out of suture, so, mobile for the suture of extended state by retreating continuously of line seizure parts 71, can automatically tangle the suture front end and keep.
Then, making processing finishes.
(effect of embodiment)
As mentioned above, in button sewing machine 100, not only by carrying out handling the needle of button continuously by starter pedal 89 the making instruction of input, the cut-out of suture, a series of action controls of making action such as the end maintenance of suture, and, because input by line maintained switch W3, can only be inserted in the action control that the end of suture of the through wires hole of suture keeps individually, so, the state once made of execution after power switch 84 input and as yet, carried out the state of the replacing of eedle and suture, as working as situations such as generation broken needle or broken string restart to make, under the situation of also not carrying out the line maintenance, do not need to utilize handwork to keep or give up to make and carry out line and keep, thereby can carry out keeping, eliminated numerous and diverse property as the line of single movement by line, and, can realize the raising of operating efficiency.
In addition, by only can be at threading picture display line maintained switch W3, after power switch 84 input and the as yet state once made of execution, the state that has carried out the replacing of eedle and suture, as working as situations such as generation broken needle or broken string restart to make, when being necessary to carry out threading before the online maintenance, can carry out this threading preparation work and maintenance continuously by Sewing machines, thereby, can realize the high efficiency of operation.
In addition, the action of the line holding device 70 that is undertaken by line maintained switch W3, it is different that line during with common sewing finishing is caught the continuous advance and retreat action of parts 71, stop at progressive position owing to can make line catch parts 71, so, can be by the operating personnel of Sewing machines, the front end that will be the suture of overhang from the front end of suture keeps on the online capture unit part 71 reliably.
