(1) tangent mechanism
(a) structure of tangent mechanism
Tangent line connecting rod 11 forms slight curving along long bar-shaped of a direction in the centre.One end of tangent line connecting rod 11 and cam 7 link, and this cam 7 is supported by the output shaft 2a axle of pulse motor 2.Tangent line connecting rod 11 is installed on the not shown sewing machine stand by supporting pin 12 at bend 11b place free to rotately.
The other end 11c of tangent line connecting rod 11, is installed on the installing plate 16 by bolt 17 with the state that can freely rotate with an end of tangent line connecting rod 13.
Tangent line connecting rod 13 is that its leading section 13a (with reference to Fig. 2) is set to, and is positioned at the below of needle plate 8 at the crooked upward gradually bar-like member of assigned position, i.e. the below of the suture needle 6 that is kept by needle bar 5.
As shown in Figure 2, on leading section 13a, link movable cutting knife free to rotately link parts 20 via bolt 21.And, link on the parts 20 fixedly tangent line lever 23 at movable cutting knife.Insert the connecting pin 22 that is fixed on the needle plate 8 on movable cutting knife binding parts 20 and tangent line lever 23, making movable cutting knife binding parts 20 and tangent line lever 23 can be that rotate together at the center with connecting pin 22.One end 24a of movable cutter connecting rod 24 is connected with the front end of tangent line lever 23 free to rotately.
The middle body of movable cutting knife 15 links with the other end 24b of movable cutter connecting rod 24 free to rotately.The end 15a of movable cutting knife 15 is installed on the dogbolt 25 free to rotately.Dogbolt 25 is fixed on the needle plate 8.Front end at movable cutting knife 15 is formed with: the 15b of take-up portion, and it is provoked when cutting off action and reaches the standard grade and roll off the production line and not with its cut-out; Suture capture unit 15c, it is crooked to the inside, is used to catch the suture of being provoked by the 15b of take-up portion; And movable cutting edge 15d, it is used for suture is cut off.Setting is by being bolted to the fixed cutting tool 14 on the needle plate 8 near movable cutting knife 15, and clamping is reached the standard grade and rolled off the production line and with its cut-out between fixed cutting tool 14 and movable cutting knife 15.
(b) action of tangent mechanism
Below, the action of tangent mechanism 1 is described.For tangent mechanism 1, finish if make, then before presser feet lifts,, the output shaft 2a of pulse motor 2 is rotated around axis by driving pulse motor 2.If output shaft 2a rotation, the cam 7 that then is arranged on the output shaft 2a also rotates with output shaft 2a.If cam 7 rotation, 11 on the tangent line connecting rod that links with cam 7 is the center with supporting pin 12, and along counterclockwise rotating, move its bottom forwards (cutting knife side) towards the paper of Fig. 1.Thus, tangent line connecting rod 13 is forwards moved, link parts 20, so movable cutting knife links parts 20 and tangent line lever 23 is the center rotation with binder bolt 22 via the movable cutting knife of bolt 21 pushings.
Shown in Fig. 3 (a), by the action of tangent line lever 23, the movable cutter connecting rod 24 that pushing rearward is connected with its front end, making movable cutting knife 15 is that the center rotates along clockwise direction with dogbolt 25.By this spinning movement, reach the standard grade and roll off the production line by the 15b of take-up portion sorting, only make reaching the standard grade and roll off the production line between suture capture unit 15c and counteredge 14a of should cutting off.
On the other hand, if tangent line connecting rod 11 is the center with supporting pin 12, rotate along clockwise direction towards the paper of Fig. 1, make its bottom return the rear, each parts that then constitute tangent mechanism 1 carry out opposite action.That is to say, movable cutting knife 15 is rotated action and returns original state with the state from Fig. 3 (b), caught when reaching the standard grade and rolling off the production line by suture capture unit 15c and rotate this moment, make thus and reach the standard grade and roll off the production line gradually near counteredge 14a, shown in Fig. 3 (c), movable cutting edge 15d aligns with counteredge 14a and suture is cut off.Movable cut part 15 continues counter-rotating with this state, returns the state of Fig. 3 (a).
(2) pulse motor
As shown in Figure 1, pulse motor 2 carries out drive controlling by control device 4.The action of tangent mechanism 1 is by by this control device 4, on one side the direction of rotation of paired pulses motor 2 and the umber of pulse in the action count, control the action of cam 7 on one side and carry out.
Utilize known PWM to control from the moment of torsion of pulse motor 2 outputs,, can increase from the moment of torsion of pulse motor 2 outputs by increasing the pulsewidth of command pulse.That is to say,, can regulate the moment of torsion of output by changing the pulsewidth of command pulse.
(3) encoder
As shown in Figure 1, encoder 3 is arranged on the output shaft 2a of pulse motor 2, the pulse of the driving output of the output shaft 2a of detection pulse motor 2.
(4) control device
(a) structure of control device
As shown in Figure 4, control device 4 has pulse efferent 41, and it is when driving pulse motor 2, to these pulse motor 2 input command pulses.That is to say that pulse efferent 41 works as the pulse output unit.
In addition, the threshold data 44b of memory load moment of torsion in storage part 44, this threshold data 44b is when whether the fixed cutting tool 14 of judging tangent mechanism 1 or movable cutting knife 15 contacts with suture needle 6, is positioned at the threshold data that is applied to the load torque on the pulse motor 2 at its judgement boundary condition place.That is to say that storage part 44 also works with the threshold value memory cell as the contact judgement.
Here, threshold data 44a, the 44b of load torque uses and gets final product by the value of measuring on the experiences such as test in advance, but because threshold data 44a uses when judging the thickness of suture, threshold data 44b is judging that tangent mechanism 1 uses when whether contacting with suture needle 6, so, threshold data 44b for applying bigger load torque sets the threshold value of its load torque bigger.And making the load torque value based on the threshold data 44a of load torque is T1, is T2 based on the load torque value of the threshold data 44b of load torque.
And various piece can be carried out by known CPU and be used to realize that the program with processing of various piece function handles.In addition, the software that the program that is not limited only to is so also can use hardware such as circuit.
The processing of the control device when (b) carrying out tangent line
Below, the processing of the control device 4 when carrying out tangent line describes.
As shown in Figure 5, when carrying out tangent line, the pulse efferent 41 of control device 4 transmits the command pulse (step S1) that is used for driving pulse motor 2 to pulse motor 2.In addition, when driving pulse motor 2, consider that the load of pulse motor 2 reduces, the high efficiency of operation, the less mode of output torque drives paired pulses motor 2 with high speed.
Then, the command pulse test section 42 detected command pulses that are sent to pulse motor 2 from pulse efferent 41 that the load torque calculating part 43 of control device 4 calculates by control device 4, and, be applied to load torque (step S2) on the pulse motor 2 based on this phase difference calculating by the phase difference between the detected output pulse that exports output shaft 2a from pulse motor 2 to of encoder 3.
Then, control device 4 judges that whether the load torque that calculates is than based on the big value of the load torque value T1 that is stored in the load torque threshold data 44a in the storage part 44 (comprising that also the load torque that calculates is identical value with load torque value T1) (step S3).Here, be value (step S3: be) if be judged as the load torque that calculates more than or equal to load torque value T1, then the drive control part 45 of control device 4 changes the command pulse that is sent to pulse motor 2 from pulse efferent 41, reduce the actuating speed of pulse motor 2, and increase output torque (step S4) from pulse motor 2.
On the other hand, if being judged as the load torque that calculates, drive control part 45 is value (step S3: not) less than load torque value T1, then judge by control device 4 whether tangent line finishes (step S5), be judged as under the situation that tangent line finishes (step S5: be) at control device 4, finish this processing, be judged as (step S5: not), return step S2 under the still uncompleted situation of tangent line at control device 4.
In step S4, after drive control part 45 reduces the actuating speed of pulse motor 2 and output torque is increased, load torque calculating part 43 calculates by the command pulse test section 42 detected command pulses that are sent to pulse motor 2 from pulse efferent 41, and, be applied to load torque (step S6) on the pulse motor 2 based on this phase difference calculating by the phase difference between the detected output pulse that exports output shaft 2a from pulse motor 2 to of encoder 3.
Then, control device 4 judges that whether the load torque that calculates is than based on the big value of the load torque value T2 that is stored in the load torque threshold data 44b in the storage part 44 (comprising that also the load torque that calculates is identical value with load torque value T2) (step S7).Here, be value (step S7: be) if be judged as the load torque that calculates more than or equal to load torque value T2, then drive and stop portion 45 and stop from pulse efferent 41 to pulse motor 2 move instruction pulses, the driving of pulse motor 2 is stopped (step S8), carry out mistake on the guidance panel on the Sewing machines 100 etc. and show (step S9) being arranged at.
On the other hand, if being judged as the load torque that calculates, control device 4 is value (step S7: not) less than load torque value T2, then drive control part 45 changes the command pulse that is sent to pulse motor 2 from pulse efferent 42, reduce the actuating speed of pulse motor 2, and increase output torque (step S10) from pulse motor 2.
Then, control device 4 judges whether to finish tangent line (step S11), is judged as under the situation that tangent line finishes (step S11: be) at control device 4, finishes this processing, be judged as (step S11: not), return step S6 under the still uncompleted situation of tangent line at control device 4.
The action effect of＜embodiment 〉
As mentioned above, according to Sewing machines 100, the tangent line operation is by driving ripple current motor 2, tangent mechanism 1 action being carried out.At this moment, command pulse test section 42 detects the command pulse that inputs to pulse motor 2 from pulse efferent 41.In addition, encoder 3 detects the output pulse of the pulse motor 2 that is driven by command pulse.
If detect command pulse and output pulse, then load torque calculating part 43 calculates by command pulse test section 42 detected command pulses with by encoder 3 detected interpulse phase differences, is applied to load torque on the pulse motor based on this phase difference calculating.
Then, under the situation of the load torque that is calculated by load torque calculating part 43 greater than the threshold data 44a that is stored in the load torque among the storage part 44a, drive control part 45 reduces the actuating speed of pulse motor 2, and increases output torque.
Thus, be judged as the load torque that calculates by load torque calculating part 43 greater than the threshold data 44a that is stored in the load torque in the storage part 44, in other words, suture is coarser than the thickness as benchmark, apply during cut-out under the situation of bigger load torque, can utilize drive control part 45 to increase the output torque of pulse motor 2.
Thus, because can only under the situation of the bigger load torque of needs, increase the output torque of pulse motor 2, so it is bad to need not to make pulse motor 2 maximizations just can suppress tangent line.
In addition, under the situation of the load torque that calculates by load torque calculating part 43, drive the driving that stops portion's 46 stop pulse motor 2 greater than the threshold data 44b that is stored in the load torque in the storage part 44.
Thus, be judged as the load torque that calculates by load torque calculating part 43 greater than the threshold data 44b that is stored in the load torque in the storage part 44, in other words, tangent mechanism 1 contacts with suture needle 6 and under situation about applying on the pulse motor 2 than the heavy load moment of torsion, can utilize to drive the driving that stops portion's 46 stop pulse motor 2.
Thus, in these cases, because can the action of tangent mechanism 1 also be stopped by the driving of stop pulse motor 2, so, also can prevent broken needle even under the state that suture needle 6 is descended, carry out tangent line.
(other)
In addition, the present invention is not limited only to above-mentioned embodiment.For example, in the above-described embodiment, adopt control device 4 to have drive control part 45 and drive and stop the structure of portion 46, but also can adopt the structure that has among both any one.
In addition, for drive control part 45 because only defined a threshold value, thus only be the thick line or the judgement of fine rule, but also can be by setting a plurality of threshold values, and with the thickness of the suture further drive controlling of refinement pulse motor 2 accordingly.
