On the input interface 56 of control device 55, as shown in figure 10, connecting selector switch 9b, wire clamp holds mode switch 9c, configuration switch 9d, initial setting switch 9e, the 1st switch 18a, the 2nd switch 18b, origin sensor 48, removes sensor 49 and encoder 73.The 1st switch 18a is depressed to the 1st grade compress position according to pedal 18 and is switched on, and CPU57 judges pedal 18 and has been depressed to the compress position detecting on the basis that the 1st switch 18a connects.The 2nd switch 18b is depressed to the 2nd grade sewing position according to pedal 18 and is switched on, and CPU57 judges pedal 18 and has been depressed to sewing position detecting on the basis that the 2nd switch 18b connects.Encoder 73 is rotary-type members of a kind of rotation amount at each main shaft output pulse signal when arriving unit value (such as 1 degree), CPU57 is according to the instrumentation from the number of pulse signals of encoder 73 output, the rotatable phase angle of detection main shaft in the scope of 1 degree～360 degree (0 degree).
In the ROM58 of control device 55, record control program and control data, the CPU57 of control device 55 is according to control program and control data, to sewing machine electromotor 67, push motor 68, wire clamp is held motor 36, trimming solenoid 69, X-axis drive motor 70 and Y-axis drive motor 71 and is controlled, on processing cloth W, form noose and reinforce stitching.The following describes the control content of control device 55.
When the CPU57 of control device 55 connects power supply, in the step S11 of Figure 11, the mode of operation of initial setting switch 9e is judged.At this, when detecting initial setting switch 9e on, set the processing back through the initial point of step S12 and divide a word with a hyphen at the end of a line to step S13, when detecting initial setting switch 9e access failure, the setting of the initial point of skips steps S12 is handled the back and is divided a word with a hyphen at the end of a line to step S13.The initial point of this step S12 set handle be according to wire clamp hold motor 36 driving shaft 36a counter-rotating and by initial setting in origin position, the driving shaft 36a that holds motor 36 when this wire clamp is by initial setting during in origin position, the 2nd line grip block 22 contacts with retainer (not shown), is positioned starting position (S).
The step S13 in case divide a word with a hyphen at the end of a line, CPU57 close the connection of the 1st switch 18a and judge.To process cloth W such as the operator and be placed on the needle plate 12, when pedal 18 was depressed to the 1st grade compress position, the 1st switch 18a connected, and CPU57 detects the connection of the 1st switch 18a in step S13, and S14 divides a word with a hyphen at the end of a line to step.
The step S14 in case divide a word with a hyphen at the end of a line, CPU57 be according to the driving of pushing motor 68, and to the compress position, the processing cloth W on the needle plate 12 is pressed from the top by presser feet 13 with presser feet 13 move operations.Divide a word with a hyphen at the end of a line to step S15 then, the connection of the 2nd switch 18b is closed judge.When such as the operator pedal 18 being depressed to the 2nd grade sewing position, the 2nd switch 18b connects, and CPU57 detects the connection of the 2nd switch 18b in step S15, and S16 divides a word with a hyphen at the end of a line to step.
The step S16 in case divide a word with a hyphen at the end of a line, the connection that CPU57 holds mode switch 9c to wire clamp is closed and is judged.At this, divide a word with a hyphen at the end of a line to step S17 when holding mode switch 9c on when detecting wire clamp, judge having or not the initial point signal.When having detected the initial point signal, S21 divides a word with a hyphen at the end of a line to step, and when detecting no initial point signal, S18 divides a word with a hyphen at the end of a line to step.
The step S18 in case divide a word with a hyphen at the end of a line, CPU57 make wire clamp hold motor 36 counter-rotatings, in step S19 having or not of initial point signal are judged, and in step S20 the instrumentation value and the higher limit of reversing time are made comparisons.This reversing time be exactly in step S18, CPU57 holds motor 36 this state that begins to reverse to wire clamp and begins time of instrumentation, before the instrumentation value of reversing time arrives higher limit, when CPU57 detected the initial point signal in step S19, S21 divided a word with a hyphen at the end of a line to step.Again, when the instrumentation value that detects reversing time not detecting the initial point signal in step S20 had arrived higher limit, S22 divided a word with a hyphen at the end of a line to step.At this moment, in LCD 9a, show error message, finish running.That is, wire clamp is held motor 36 and is begun after the counter-rotating, even passed through setting-up time the 2nd line grip block 22 also under the situation of no show starting position (S), is judged to be and has taken place unusually, finishes running.
The step S21 in case divide a word with a hyphen at the end of a line, CPU57 drives sewing machine electromotor 67.So shank 10, thread take-up tension lever 72 and delivery sheet 14 starts begin to make processing.Figure 12 is the time figure that expression suture needle 11 is moved and thread take-up tension lever 72 moves in time series.The transverse axis of this Figure 12 is represented the rotatable phase angle of main shaft, and the longitudinal axis is represented the position (being called height and position) of the above-below direction of suture needle 11 and thread take-up tension lever 72, and chain-dotted line is represented the height and position of needle plate 12 upper surfaces.As shown in figure 12, main shaft revolves three-sixth turn at every turn, suture needle 11 is got back to top dead-centre from top dead-centre via bottom dead centre linkedly, moving to from top dead-centre the way of bottom dead centre, run through in the line hole 22b of the 2nd line grip block 22 from the pin hole 12a of needle plate 12, move to the way of top dead-centre from bottom dead centre, in the pin hole 12a of the line hole 22b of the 2nd line grip block 22 and needle plate 12, deviate from.Suture needle 11 is deviate from from the pin hole 12a of needle plate 12, and in the way of rising, thread take-up tension lever 72 rises, and stitching is strained.
In the step S21 of Figure 11, begin to make when handling, CPU57 in step S23 according to detecting from the output signal of encoder 73 rotatable phase angle θ to main shaft, with the testing result of rotatable phase angle θ be recorded in lower limit 0 degree among the ROM58 and higher limit 30 in advance and spend and make comparisons.At this, when the testing result that detects rotatable phase angle θ is in lower limit 0 and spends to the scope of higher limit 30 degree, be judged to be and arrive the clamping time point, S24 divides a word with a hyphen at the end of a line to step.The rotatable phase angle of this main shaft be in 0 the degree to 30 the degree scopes in the time, as shown in figure 12, suture needle 11 is deviate from from the pin hole 12a of needle plate 12, and, along with stitching is strained in the rising of thread take-up tension lever 72.
The step S24 of Figure 11 in case divide a word with a hyphen at the end of a line, CPU57 is additional to wire clamp at the pulse signal that will set number with positive revolving die formula and holds on the basis of motor 36, and making wire clamp hold motor 36 is just changeing.The driving shaft 36a that this pulse signal can only make wire clamp hold motor 36 is just changeing the 1st angle [alpha] 1, the 2 line grip block 22 and is holding motor 36 according to the wire clamp in step S24 and just changeing, and (S) turns to clip position (K) from the starting position.That is, (S) moves to clip position (K) the 2nd line grip block 22 from the starting position in the stitching of the 1st pin is strained.Under this state, along with stitching is tightened up, the contraction in length of thread end 7a is about 2cm～3cm, along with the 2nd line grip block 22 arrives clip position (K) in step S24, the thread end 7a of 2cm～3cm left and right sides length be clamped in and the 1st line grip block 21 between.
In step S24, in case 7 the thread end 7a clamping of will reaching the standard grade, CPU57 judges having or not of initial point signal in step S25.At this, when having detected the initial point signal, in step S26, sewing machine electromotor 67 is closed, in step S27, LCD 9a goes up and shows error message.That is, in step S24,,, be judged to be and taken place unusually, make to handle and stop when the 2nd line grip block 22 when (S) is not mobile from the starting position even hold motor 36 extra-pulse signals to wire clamp.
If detect no initial point signal in step S25, CPU57 carries out standby in step S28, until forming the stitching of setting pin number (such as 3 pins).This pin number is recorded among the ROM58 of control device 55 in advance.CPU57 according in step S28 to instrumentation from the pulse signal of encoder 73, the rotation amount of main shaft is detected, make the judgement that forms the stitching of setting the pin number according to the testing result of rotation amount.That is, from straining the 1st needlework mark during form the 3rd needlework mark, 7 the thread end 7a of reaching the standard grade continues to be held between the 1st line grip block 21 and the 2nd line grip block 22, and the 2nd needlework mark and the 3rd needlework mark form under the clamp position of thread end 7a.
Form the stitching of setting the pin number if be judged as in step S28, CPU57 will set number with positive revolving die formula in step S29 pulse signal is additional to wire clamp and holds on the basis of motor 36, and making wire clamp hold motor 36 is just changeing.The driving shaft 36a that this pulse signal can only make wire clamp hold motor 36 rotates the 2nd angle [alpha] 2, the 2nd line grip block 22 is held motor 36 according to the wire clamp in step S29 just to be changeed, turn to from clip position (K) and to remove position (L), self confining force that relies on wire clamp to hold motor 36 is held in removes position (L).That is, 7 the thread end 7a of reaching the standard grade is that condition is carried out clamping and removed to form the 3rd needlework mark, and it is to carry out under the disarm state of the thread end 7a that the 1st line grip block 21 and the 2nd line grip block 22 has been moved to releasing position (L) that later making handled.
If in step S29, hold motor 36 and added pulse signal to wire clamp, CPU57 in step S30 to having or not ring off signal to judge.At this, when detecting no ring off signal, in step S26, sewing machine electromotor 67 is closed, among the step S27, on LCD 9a, show error message.That is, added pulse signal, when position (L) is removed in 22 no shows of the 2nd line grip block, also be judged as and taken place to finish to make processing unusually even in step S29, hold motor 36 to wire clamp.
If detected ring off signal among the step S30, CPU57 closes the connection of the 2nd switch 18b in step S31 and judges.Such as, when the operator with pin when pedal 18 leaves, pedal 18 returns initial position from sewing position, the 2nd switch 18b closes.This occasion, CPU57 makes detection to closing of the 2nd switch 18b in step S31, in step S32 sewing machine electromotor 67 is closed.So the action of suture needle 11, thread take-up tension lever 72 and delivery sheet 14 stops, finishing to make processing.
If finish to make processing in step S32, the divide a word with a hyphen at the end of a line trimming of step S33 of CPU57 is handled.At this, along with the driving of trimming solenoid 69, moving knife 31 carries out rotating operation, between moving knife 31 and stationary knife 30, will reach the standard grade 7 and the both sides of rolling off the production line cut off, divide a word with a hyphen at the end of a line to step S34 then, the pulse signal that will set number with reversing mode is additional to wire clamp and holds motor 36.This pulse signal can only make wire clamp hold the driving shaft 36a counter-rotating " the 1st angle+the 2nd angle " of motor 36, the 2nd line grip block 22 is according to making wire clamp hold the driving shaft 36a counter-rotating " the 1st angle+the 2nd angle " of motor 36 in step 34, the driving force that relies on wire clamp to hold motor 36 is returned starting position (S) from removing position (L), along with the 2nd line grip block 22 from removing the rotation that starting position (S) returned in position (L), the 1st line grip block 21 utilizes the elastic force of retracting spring 26 to return clip position (K) from removing position (L).
Hold mode switch 9c and be closed if detect wire clamp in step S16, CPU57 is additional to wire clamp according to the pulse signal that will set number with positive revolving die formula in step S35 and holds motor 36, and making wire clamp hold motor 36 is just changeing.So (S) turns to releasing position (L) from the starting position with the 2nd line grip block 22, the 1st line grip block 21 is turned to from clip position (K) remove position (L).
If in step S35, hold motor 36 and added pulse signal to wire clamp, CPU57 in step S36 to having or not ring off signal to judge.At this, when detecting no ring off signal, S22 divides a word with a hyphen at the end of a line to step, shows error message and finish running on LCD 9a.That is, added pulse signal, when position (L) is removed in 22 no shows of the 2nd line grip block, also be judged as and taken place to finish running unusually even in step S35, hold motor 36 to wire clamp.
If CPU57 has detected ring off signal in step S36, S37 divides a word with a hyphen at the end of a line to step.At this, begin to make processing according to the connection of sewing machine electromotor 67, S31 divides a word with a hyphen at the end of a line to step.That is, under the closed condition of online clamping mode switch 9c, reach the standard grade 7 thread end 7a ground of not clamping is carried out and is made processing.
If detecting the 2nd switch 18b in step S31 is closed, CPU57 stops making processing according to the closed condition of sewing machine electromotor 67 in step S32.Then, driving according to trimming solenoid 69 in step S33, to reach the standard grade 7 and the cut-out of rolling off the production line, be additional to wire clamp according to the pulse signal that in step S34, will set number and hold motor 36 with reversing mode, make the 2nd line grip block 22 return starting position (S), make the 1st line grip block 21 return clip position (K) from removing position (L) from removing position (L).
Adopt the foregoing description, can obtain following effect.
When the 2nd line grip block 22 was in starting position (S), the line hole 22b of the pin hole 12a of needle plate 12 and the 2nd line grip block 22 was arranged side by side on above-below direction.Under this state, when suture needle 11 descends, in pin hole 12a, advance in the line-entering hole 22b, when suture needle 11 is risen, in the 22b of line hole and in the pin hole 12a, deviate from.When this suture needle 11 was deviate from, 7 the thread end 7a of reaching the standard grade stayed in the line hole 22b of the 2nd line grip block 22.Under the state in this thread end 7a stays line hole 22b, when the 2nd line grip block 22 when (S) moves to clip position (K) from the starting position, thread end 7a is clamped between the 1st line grip block 21 and the 2nd line grip block 22, when the 2nd line grip block 22 moves to when removing position (L) from clip position (K) thread end 7a is discharged.Like this, can be till make beginning and be clamped to stitching that form to set the pin number always with thread end 7a, so the bouncing pilotage generation can prevent to make beginning the time.And, the 2nd line grip block 22 is rotated between starting position (S), clip position (K), releasing position (L).Like this, since no longer need to the 2nd wire clamp hold the linearity moving direction channeling conduct of member 22 many connecting rods, many connecting rods of supporting parts and generate a plurality of cylinders etc. that the 2nd wire clamp is held the member locomotivity, so can make simplifying the structure of the clamping components 20 of reaching the standard grade.And, since with the 2nd line grip block 22 from the starting position (S) move operation to the releasing position (L) wire clamp hold motor 36, be accommodated in the base plate 2 and rearward end needle plate 12 reverse side, make base plate 2 maximizations so to prevent to be subjected to wire clamp to hold the influence of motor 36.
The clip position (K) of the 2nd line grip block 22 is set in makes the 2nd line grip block 22 (S) rotated the position of the 1st angle [alpha] 1 towards direction initialization from the starting position, with the releasing position (L) of the 2nd line grip block 22 be set in make the 2nd line grip block 22 from clip position (K) towards having rotated the position of the 2nd angle [alpha] 2 with the same direction of direction initialization.Like this, corresponding with the rotation that the 2nd line grip block 22 carries out, the 2nd line grip block 22 leaves from suture needle 11, arrives at the 2nd line grip block 22 and removes in the positions (L) gap pin 11 farthest, makes when handling thread end 7a and is sewed up and process among the cloth W so can prevent to carry out.
The 1st line grip block 21 is by being pushed by the engagement pin 27 of the 2nd line grip block 22, operate releasing position (L) from clip position (K), utilize the elastic force of retracting spring 26 to return clip position (K), so do not need to be provided with the actuator that makes the reciprocal special use between clip position (K) and releasing position (L) of the 1st line grip block 21 from removing position (L).
Utilize the engaging power between retainer 21d and hub portion 22d that the 1st line grip block 21 is remained in clip position (K).Like this, can reliably the 1st line grip block 21 be remained in clip position (K), so between the 1st line grip block 21 and the 2nd line grip block 22, can be reliably 7 thread end 7a clamping will be reached the standard grade.
The 1st pin 23 of the 1st line grip block 21 is configured in the rear side of the pin hole 12a of needle plate 12, the 2nd pin 24 of the 2nd line grip block 22 is configured in the rear side of the 1st pin 23, therefore, releasing position (L) mutual dislocation of the releasing position (L) of the 1st line grip block 21 and the 2nd line grip block 22, like this, arrive the 1st line grip block 21 and the 2nd line grip block 22 both sides that remove can be open with the line hole 22b of the 2nd line grip block 22 reliably in the position (L), so also can reliably the clamping of thread end 7a be removed, and, because of not needing to remove the special mechanism of thread end 7a clamping, so can make threading holder 20 miniaturizations and simplification.
Be under the state of starting position (S) at the 2nd line grip block 22, the coincidence part 22g of the 2nd line grip block 22 overlaps with the 1st line grip block 21 from the below, when the 2nd line grip block 22 when (S) moves to clip position (K) from the starting position, the 2nd line grip block 22 and the 1st line grip block 21 can not collided.Like this, (S) moves to clip position (K) from the starting position successfully to make the 2nd line grip block 22 with setting speed, so can be apace will reach the standard grade 7 thread end 7a clamping.
Use 48 pairs the 2nd line grip blocks 22 of origin sensor to be in starting position (S) and made detection.Like this, can detect the abnormality that the 2nd line grip block 22 is not in starting position (S), can make error message and show or shut down.
Detect the 2nd line grip block 22 by releasing sensor 49 and be in releasing position (L).Thus, can detect the 2nd line grip block 22 and not be in the abnormality of removing position (L), or show error message or shut down.
Adopted the structure of 7 the thread end 7a clamping of will reaching the standard grade in the 1st line grip block 21 and the 2nd line grip block 22 left field (zone of deflection chassis portion 2 short side directions, one side) under suture needle 11.Like this, far because of thread end 7a gap pin 11, can prevent when handling that thread end 7a from being sewed up among the processing cloth W so make.
Because the 1st line grip block 21 and the 2nd line grip block 22 are installed in rotation on the needle plate 12, the 1st line grip block 21 and the 2nd line grip block 22 are integrated with needle plate 12.And, connecting pin 46 is fixed on wire clamp holds on the connecting rod 45 towards the top, connecting pin 46 is inserted among the connecting hole 22f of the 2nd line grip block 22.Like this, to be used for the many screws that needle plate 12 is fixed on the base plate 2 are taken off, only need lift needle plate 12 and can remove engaging between connecting pin 46 and connecting hole 22f, needle plate 12 is taken out from base plate 2 with the 1st line grip block 21 and the 2nd line grip block 22, so can clean foreign matters such as the end of a thread that is attached to below the needle plate 12 and dust simply.
In the foregoing description, the 1st line grip block 21 is installed in rotation on the needle plate 12, is not limited to this example, such as also being mounted to inactive state.This occasion, also can when turning to releasing position (L), clip position (K) can make the line hole 22b of the 2nd line grip block 22 dispose the 1st line grip block 21 according to the 2nd line grip block 22 by the requirement of the 1st line grip block 21, because of line hole 22b passes through the 1st line grip block 21, can remove the clamping of thread end 7a.
In the foregoing description, the 2nd line grip block 22 is rotated towards the left and right sides opposite direction with Fig. 4, the 1st line grip block 21 is configured at the left and right sides of Fig. 4 opposite direction, and make the 2nd line grip block 22 towards rotating with the counter clockwise direction of Fig. 4, on this basis, move operation is to clip position and releasing position.
In the foregoing description, used stepping motor to hold motor 36, be not limited to this example as wire clamp, but such as the dc motor that also can use FEEDBACK CONTROL.
In the foregoing description,, be not limited to this example, such as also using linear solenoid as (S) rotating operation has used wire clamp to hold motor 36 to the drive unit of clip position (K) from the starting position with the 2nd line grip block 22.
