From configuration switch 65, in the various parameters for carrying out filler rod, such as, sewing Spacing, sewing machine electromotor 16 rotary speed on the basis of, operator carry out following etc. Setting, i.e. parameter when lining cloth S is sewed up the i.e. sewing of filler rod shown in Fig. 9 Length c, it is which in benchmark, rear benchmark before the placing of main cloth C and filler rod cloth is held Row, from the leading section of lining cloth S length to sewing starting position i.e. to sew starting side long Degree a, long from the rearward end of the lining cloth S i.e. sewing finishing side of length to sewing finishing position Degree b.

Additionally, sewing length c, sewing starting side length a and the conjunction of sewing finishing side length b Evaluation is equivalent to carry out the length of the lining cloth S supplied, and the most above-mentioned configuration switch 65 is as " right The length configuration part that the length of described lining cloth to be supplied is set " work.

Additionally, distance Fc that the past reference position F shown in Fig. 9 is to sewing position N And be fixed value from rear reference position R distance Rc to sewing position N, control device 60 storages all the time have this value.

It addition, control device 60 via each driver 16a, 25a, 17a, 94a, 34a, 444a connects the sewing machine electromotor 16 of the control object becoming this control device 60, presser feet Motor 25, cutting knife motor 17, the driving motor 94 of bevel tool, target location is electronic Machine 34, extraction motor 444.

It addition, be attached to the encoder that its rotation amount is detected in presser foot motor 25 251, this encoder 251 via to its output enumerator 251a of counting of pulse with control Device 60 processed connects.

It addition, control device 60 via driver 18a, 24a, 93a, 54a, 26a, 27a connects to be had the cylinder moved up and down carrying out hemming foot 12, carry out big presser feet 21 Lifting cylinder 23, carry out the cylinder 92 of the lifting of bevel tool 91, lining cloth feedway 40 Unclamp and control with the work of cylinder 462, locking cylinder 463 and cutting knife cylinder 483 The electromagnetic valve 18,24,93,465,466,484 of system.

Further, there is target-position display 35 at control device 60 via the connection of driver 35a Light source.

Control device 60 to possess: CPU 61, it carries out various control；And memorizer 62, It is written with the described later various functions of fillet sewing machine 10, makes the control of action executing Program, control data or various stitch data.

Above-mentioned memorizer 62 store all from configuration switch 65 input be used for carry out filler rod (sewing spacing, the rotary speed of sewing machine electromotor 16, is by master to the various parameters of sewing Which execution in benchmark, rear benchmark before the placement of cloth C and filler rod cloth, lining cloth S's Sewing starting side length a, the setting of sewing finishing side length b etc. of lining cloth S).That is, deposit Reservoir 62 works as memory element.

Above-mentioned CPU 61 is by being stored in the control program of ROM 62, in order to will be at rear benchmark In the case of the position R main cloth C of placement and filler rod cloth, lining cloth S is with extra length extraction The problem carrying out sewing up eliminates, when the sewing of rear reference position R, at suitable timing control System is unclamped with cylinder 462 and locking cylinder 463, by for lining cloth S from " stoping supply State " switch to " release stop state ", thus perform the end, front of lining cloth S The lining cloth supply carrying out para-position relative to dress material controls.

[the sewing action that the lining cloth supply comprising rear reference position controls]

In the case of sewing about being included in above-mentioned rear reference position R configuration dress material Lining cloth supply controls at interior sewing action control, by sequential chart and the stream of Figure 11 of Figure 10 Journey figure is described in detail.

Additionally, premised on following situation, i.e. lining cloth S before sewing starts, its front End is forwards extracted out from peristome 111 with sewing starting side length a (with reference to Fig. 9), will Unclamping of lining cloth feedway 40 controls to be plunger fallback state with cylinder 462, is used by locking Cylinder 463 controls to be plunger protruding state, and driven push rolls 443 is in and stops lining cloth S's The state (state of Fig. 8) of supply.

When above-mentioned, if from operator's opening by operating pedal 68 input sewing Begin, then the CPU 61 of control device 60 controls target positioning motor 34 and target location shows Show device 35, the rear reference position of the upper surface of workbench 11 is irradiated (step S1).

And, the sewing finishing position of dress material is pointed to rear reference position R and puts by operator It is placed on workbench 11, if carried out the behaviour that enters into again representing the operating pedal 68 placed Make (step S3), then CPU 61 controls cylinder 23 and makes big presser feet 21 decline, at rear base Level puts holding dress material (step S5).

Further, CPU 61 starts the driving of presser foot motor 25, starts the sewing to dress material The conveying (step S7, Figure 10: T1) of position N.

Additionally, the CPU 61 controlling device 60 controls the presser feet electricity of big presser feet feed mechanism 20 Motivation 25, so that first transporting velocity of dress material of (empty feeding) becomes before sewing starts At a high speed, the second transporting velocity of the dress material after sewing starts becomes low speed.That is, from starting conveying To the conveying started sewing to be carried out at high speed.

It follows that CPU 61 is according to the step-by-step counting of the encoder 251 of presser foot motor 25 Value judges whether dress material arrives lining cloth supply position (step S9).Owing to being the sewing of dress material Starting position has arrived the state of peristome 111 (front reference position), therefore lining cloth supply position Put by the most front with distance (Rc-c-Fc) starting from conveying and then judge.

If dress material does not arrive lining cloth supply position, then repeat judgement, if arrived (Figure 10: T2), then CPU 61 will unclamp and control to be plunger protruding state with cylinder 462, Controlling to be plunger fallback state by locking cylinder 463, driven push rolls 443 becomes upward The state separated, switch to lining cloth S supply " release stop state " (Fig. 7's State, step S11).

Thus, the constraint that lining cloth S is carried out by driven push rolls 443 is released from, by with by Friction between the dress material that big presser feet 21 keeps and forwards pull out, carry together with dress material.

It follows that CPU 61 is according to the step-by-step counting of the encoder 251 of presser foot motor 25 Value judges whether the sewing starting position of dress material arrives sewing position N (step S13).Arrive Sewing position N is by the most front with distance (Rc-c) starting from conveying and then sentence Fixed.

If dress material does not arrive sewing position N, then repeat judgement, if arriving (figure 10:T3), then CPU 61 makes the driving of presser foot motor 25 stop instantaneously, then weighs Newly start to drive, switch to the conveying (step S15) carried out with low speed.It addition, and presser feet The stopping of motor 25 synchronously starts the driving of sewing machine electromotor 16, begins through two Suture needle 13 move up and down the sewing carried out.

Additionally, presser foot motor 25 cannot stop in reality instantaneously, but little by little subtract Stopping after speed, therefore the arrival sewing position N in step S13, strictly speaking, is to arrival The position before the distance measurements needed for the stopping of presser foot motor 25 it is positioned at compared with sewing position N Put and carry out judging.

It follows that CPU 61 is according to the step-by-step counting of the encoder 251 of presser foot motor 25 Value judges whether the terminal precalculated position of lining cloth S arrives lining cloth cutting position (step S17).

Lining cloth cutting position represents that the terminal precalculated position of lining cloth S arrives the cut-out of cutting portion 48 Position.The terminal precalculated position of lining cloth S is long with sewing finishing side from sewing finishing position The position that degree b is located behind, if it is assumed that the off-position of cutting portion 48 and peristome 111 (front reference position) is compared and is located behind with distance n, then the arrival of lining cloth cutting position is logical Cross from conveying start whether the most front with distance (Rc+b-Fc-n) and then carry out judging.

If dress material does not arrive lining cloth cutting position, then repeat judgement, if arrived (Figure 10: T4), then CPU 61 will unclamp and control to be plunger fallback state with cylinder 462, Control to be plunger protruding state by cutting knife cylinder 483, driven push rolls 443 is set to neutrality State, cuts off (state of Fig. 6, step S19) by lining cloth S.

It follows that CPU 61 is according to the step-by-step counting of the encoder 251 of presser foot motor 25 Value judges whether the sewing finishing position of lining cloth S arrives sewing position N (step S21).

Sewing finishing position to the arrival of sewing position N, be by starting from conveying whether With before distance Rc and then carry out judging.

If the sewing finishing position of lining cloth S does not arrive sewing position N, then repeat Judging, if arriving (Figure 10: T5), then CPU 61 stops sewing machine electromotor 16 Drive (step S23).

And, the advance continuing big presser feet 21 is moved, and dress material is delivered to bevel tool mechanism 90, The joint-cutting (step S25, Figure 10: T6) of V shape is formed at the both ends at sewing position.

Further, if dress material entirety to be delivered to the front (Figure 10: T7) of peristome 111, Then CPU 61 performs the extraction for the lining cloth sewed next time.

Now, the plunger making cutting knife cylinder 483 retreats and is set to carry out lining cloth S's Pass.Further, since driven push rolls 443 has been positioned at neutral position, it is thus in passing through Actively the driving of push rolls 442 can carry out the state of conveying of lining cloth S.

Lining cloth S needs to start length a with sewing and forwards extracts out from peristome 111, therefore With the conjunction with distance n to peristome 111 of the off-position from aforesaid cutting portion 48 Meter distance a+n makes extraction motor 444 be driven (step S27).

In the timing (Figure 10: T8) that the extraction of above-mentioned lining cloth S completes, CPU 61 makes lock Only protrude with the plunger of cylinder 463, lining cloth S is retrained (step S29).

And, then, if being delivered to dress material carry end position, then make presser feet electronic The driving of machine 25 stops, and terminates sewing action.

Although additionally, making sewing starting side length a of lining cloth S and prior extraction length one Cause, but as shown in figure 12, front and back make lining cloth supply position by edge as shown in the arrow L in figure Put the timing variation of T2, thus scalable sews starting side length a.Such as, if will lining Cloth supply position T2 is changed to more shift to an earlier date, then sewing starting side length a can be made to be longer than thing First extraction length, if making lining cloth supply position T2 more postpone, then can make sewing open Beginning side length a is shorter than prior extraction length.

It addition, about sewing finishing side length b of lining cloth S, as shown in figure 12, by such as Along front and back making the timing of lining cloth cutting position T4 change shown in arrow K in figure, thus adjustable Joint sewing finishing side length b.Such as, if being changed to more carry by lining cloth cutting position T4 Before, then can shorten sewing finishing side length b, if making lining cloth cutting position T4 more prolong Late, then sewing finishing side length b can be increased further.

[lining cloth comprising front reference position supplies the sewing action controlled]

Lining cloth in the case of sewing about being included in front reference position F configuration dress material Supply controls, at interior sewing action control, to comprise rear benchmark with above-mentioned in addition to a part The sewing action that the lining cloth supply of position R controls is identical.Sequential chart and Figure 11 with reference to Figure 10 Flow chart its difference is illustrated.

About fillet sewing machine 10, due to be the peristome 111 that is drawn out of of lining cloth S with Front configuration consistent for reference position F, therefore before comprising, the lining cloth supply of reference position controls In the case of interior sewing action, also start lining cloth S's together with the conveying beginning of dress material Supply.

Therefore, if the sequential chart relative to Figure 10, at the conveying starting position T1 of dress material, It is changed to unclamp and is set to plunger protruding state with cylinder 462, locking cylinder 463 is set to Plunger fallback state, is changed to shorten further from the conveying starting position T1 of dress material to sewing Period till the T3 of position, then become what the lining cloth supply comprising front reference position controlled The sequential chart of sewing action.

If it addition, the flow chart relative to Figure 11, omitting supplying to lining cloth of step S9 The judgement of the arrival of position T2, protruding step S11 to the plunger unclamping use cylinder 462 State, action control to the plunger fallback state of locking cylinder 463 are changed to and step The driving of the presser foot motor 25 of S7 starts the content synchronously performed, then become and comprise front base The lining cloth supply that level is put controls the flow chart in interior sewing action.

[effect of embodiment]

Above-mentioned fillet sewing machine 10 possesses control device 60, and this control device 60 controls Sewing machine electromotor 16 and big presser feet feed mechanism 20, with corresponding to being configured at dress material in work The front benchmark position of sewing starting position para-position set by the upper surface of station 11, that make dress material Put F or make dress material the para-position of sewing finishing position rear reference position R in which, And sew to sewing finishing position from sewing starting position for the dress material carried.

It addition, lining cloth feedway 40 possesses to unclamp uses cylinder 462 and locking cylinder 463, They are to supplying the state of lining cloth S with the conveying of big presser feet 21 and can not supply lining cloth S State switch over, control device 60 control by unclamping with cylinder 462 and locking cylinder The state switching that 463 are carried out, so that in the case of rear reference position configuration dress material, relatively The para-position of the sewing starting position of lining cloth S is carried out in the dress material carried by big presser feet 21.

Thereby, it is possible in the case of rear reference position configuration dress material, it is to avoid with big presser feet 21 Conveying start start the supply of lining cloth S together and carry out the stitching of the lining cloth S of extra length, Stitching can be formed in predetermined position at lining cloth S.Therefore, at reference position and rear benchmark In the case of any one in position sews, can relative to dress material in position Supply lining cloth, after sewing, it is possible to need not the operation excised by extra lining cloth.

It addition, cylinder 462 and locking cylinder 463 are used in unclamping of lining cloth feedway 40, Can be for the lining cloth S of the state that can supply with the conveying of big presser feet 21, in the big pressure of antagonism Foot 21 and switch over, therefore with logical in stoping the state of supply and releasing the state of this prevention Often the end, front of lining cloth S is set to backoff state and before the timing needed makes lining cloth S The situation of the downside that cephalic par inserts big presser feet 21 is compared, it is possible to reduce the generation that supply is bad, The reliability of supply action can be improved, and reduce the position deviation of lining cloth and carry out high accuracy Sewing.

It addition, fillet sewing machine 10 possesses the configuration switch 65 as length configuration part, Lining cloth feedway 40 has the cutting portion 48 cut off by the lining cloth S supplied, if passed through Lining cloth S with set Length Quantity pull-out, is then controlled device 60 and controls to cut by big presser feet 21 Disconnected portion 48 is to cut off lining cloth S.

Thus, fillet sewing machine 10 can at random be set for the lining cloth S's of supply Length.

It addition, configuration switch 65 due at random set sewing length c, sewing starting side long Degree a and sewing finishing side length b, therefore, it is possible at random regulate these parameters, it is possible to according to Need to carry out galore the stitching of lining cloth S.

[other examples (1) that lining cloth supply controls]

In fillet sewing machine 10, the end, front of lining cloth S is set in advance from opening State that portion 111 stretches out and caught by the big presser feet 21 forwards moved and supply, but If big presser feet 21 is carried out at high speed movement with a certain degree of, it is likely that occur at lining cloth S Skid and cannot be caught by big presser feet 21 and not supply.

Therefore, as shown in figure 13, CPU 61 can also carry out following control, i.e. at clothing Expect (Figure 13: T2) when reaching lining cloth supply position, make the driving moment of presser foot motor 25 Ground stops, and then restarts to drive, again returns to the conveying being carried out at high speed.

Thereby, it is possible to make the end, front of lining cloth S reliably be caught by big presser feet 21, reduce Lining cloth S supplies bad generation.

Additionally, in the example of Figure 11, Figure 13, when the beginning of sewing, the conveying of dress material During the switching of speed or during the supply of lining cloth, control as making presser foot motor 25 stop instantaneously Stop, but be not limited to stop, it is also possible to controlling as temporarily slowing down.

[other examples (2) that lining cloth supply controls]

As illustrated as the former, in fillet sewing machine 10, to enter at the sky being not accompanied by sewing Carrying at high speed in the case of giving, the mode carried in the case of with sewing controls low speed Presser foot motor 25.

In this case, if the length of the lining cloth S used is short, the most as shown in figure 14, Sometimes, before arriving sewing position T3, lining cloth cutting position T4 is arrived.

In these cases, dress material and lining cloth S must be with the speed of sky feeding, the highest Speed carries out feeding, cutting portion 48 carry out the cut-out of the terminal of lining cloth.

But, will be difficult so that the terminal part of the lining cloth S of pull-out cuts off exactly at a high speed, There is a possibility that the length of lining cloth S, the formation precision of sewing finishing side length b reduces.

Therefore, the arrival generation to lining cloth cutting position T4 at lining cloth S is starting to sewing In the case of before the arrival of the sewing position T3 of position, can carry out at dress material to lining cloth Make that the driving of presser foot motor 25 stops instantaneously, to figure during the arrival of supply position T2 The lining cloth supply after improveing further that controls of 13 controls.

Specifically, as shown in figure 14, presser feet electricity is made at arrival lining cloth supply position T2 When the driving of motivation 25 restarts after stopping instantaneously driving, in this moment, not produce Empty feed speed at a high speed, and switch to the feed speed with the low speed during conveying sewed Mode controls presser foot motor 25.

As it has been described above, lining cloth supply position T2 and after, by utilizing presser foot motor Conveying is switched to low speed by 25, even if thus at lining cloth cutting position T4 and sewing position T3 Compare forward in the case of, it is also possible to carry out accurately at cutting portion 48 with lower-speed state The cut-out of the terminal part of lining cloth S.

Additionally, compared with the arrival of sewing position T3, the arrival of lining cloth cutting position T4 is No first occur, be according to for carrying out the setting value of the various parameters of filler rod by controlling device The CPU 61 of 60 judges in advance, and determines the execution of above-mentioned control.

That is, if compared with the fed distance (Rc-c) arriving sewing position T3, arrive The fed distance (Rc+b-Fc-n) of lining cloth cutting position T4 is little, then should perform to serve as a contrast Cloth supply position T2 and later transporting velocity thereof switch to the control of low speed.If further Simplify execution condition, then, when Fc+n ＞ b+c, control device 60 and be judged to perform to serve as a contrast Cloth supply position T2 and later transporting velocity thereof switch to the control of low speed.

The flow chart of the process performing Figure 14 is shown at Figure 15.

CPU 61 is based on being inputted sewing by operating pedal 68, perform by target position Put the display 35 irradiation (step S31) to rear reference position, if based on this rear benchmark The placement of the dress material of position completes and operating pedal 68 (step S33) of again entering into, then make Big presser feet 21 declines (step S35), starts the high speed conveying carried out by presser foot motor 25 Driving (step S37, Figure 14: T1).

It follows that CPU 61 judges whether dress material arrives lining cloth supply position (step S39), If arrived (Figure 14: T2), then CPU 61 makes the driving of presser foot motor 25 instantaneously Stop, then restarting to drive, switch to the conveying (step S41) of low speed.

Further, CPU 61 will unclamp and control to be plunger protruding state with cylinder 462, by locking Control to be plunger fallback state with cylinder 463, switch to " the releasing resistance of the supply of lining cloth S State only " (step S43).Thus, lining cloth S carries together with dress material.

It follows that CPU 61 judges whether the terminal precalculated position of lining cloth S arrives lining cloth cutting Position (step S45), if arriving (Figure 14: T4), then CPU 61 will unclamp and use gas Cylinder 462 controls to be plunger fallback state, controls to be plunger protruding state by cutting knife cylinder 483, Lining cloth S is cut off (step S47).

It follows that CPU 61 judges whether dress material arrives sewing position N (step S49), If arrived (Figure 14: T3), then CPU 61 makes the driving of presser foot motor 25 instantaneously Stop, then restarting to drive, and again perform the conveying (step S51) of low speed.

Thereafter, CPU 61 judges whether the sewing finishing position of lining cloth S arrives sewing position N (step S53), if arriving (Figure 14: T5), then to stop sewing machine electronic for CPU 61 The driving (step S55) of machine 16.

And, dress material is delivered to bevel tool mechanism 90, is formed at the both ends at sewing position The joint-cutting (step S57, Figure 14: T6) of V shape.

Further, if dress material entirety is delivered to front compared with peristome 111 (Figure 14: T7), then CPU 61 makes the plunger of cutting knife cylinder 483 retreat, by extracting motor 444 out Perform the extraction (step S59) of lining cloth.

If the extraction of lining cloth S completes (Figure 14: T8), then CPU 61 makes locking gas The plunger of cylinder 463 protrudes, and lining cloth S is retrained (step S61).

Further, if being delivered to dress material carry end position, then presser foot motor 25 is made Drive and stop, terminating sewing action.

As it has been described above, control device 60 to constitute following structure, i.e. such as Figure 13 and Figure 14 Shown in step S41 of lining cloth supply position T2 and Figure 15, control this big presser feet feed mechanism 20 so that kept by big presser feet 21 and carry lining cloth S time, by big presser feet feeding The transporting velocity that mechanism 20 produces reduces or stops, therefore, it is possible to reduce former due to skidding etc. Big presser feet 21 because causing catches bad generation to lining cloth S, it is possible to increase supply action Reliability, and reduce the position deviation of lining cloth S and carry out high-precision sewing.

It addition, control the CPU 61 of device 60 as illustrated as the former, it is to control big presser feet to enter To the presser foot motor 25 of mechanism 20 so that sewing start before the dress material of (empty feeding) First transporting velocity becomes at a high speed, and the second transporting velocity sewing the dress material after starting becomes low speed Situation premised on (with reference to step S15 of Figure 11).

And, control device 60 by by the lining cloth set by length configuration part length (a, B, c), it is determined that the cut-out of the lining cloth S carried out by cutting portion 48 whether in sewing advance Row (compared with the arrival with sewing position T3, the most first send out by the arrival of lining cloth cutting position T4 Raw), and, in the case of being breaking at and carry out before sewing starts of lining cloth S, in sewing Starting position arrive lining cloth supply position T2 moment, control presser foot motor 25 so that Carry out carrying (step S41 of Figure 15) in this moment and deceleration later thereof, make lining cloth S Cut-out time transporting velocity become the speed lower than the first transporting velocity (with the second transporting velocity Identical speed).

Thereby, it is possible to the terminal part of the lining cloth S pulled out with low speed is cut off, it is possible to more accurate True length is cut off, it is possible to realize the length of lining cloth S, sewing finishing side length b Form the raising of precision.

[other]

Above-mentioned fillet sewing machine 10 carries out following control, i.e. by the front end of lining cloth S Portion is set to the state making a part stretch out from peristome 111, and being set to can by big presser feet 21 The state caught, controls to unclamp to retrain with cylinder 462 and locking cylinder 463, So that lining cloth S is not pulled out by big presser feet 21, supply lining at the timing constraint relief needed Cloth S.

But, the supply of lining cloth S is not limited to said structure.

For example, it is also possible to be following structure, i.e. do not make the end, front of lining cloth S from opening Portion 111 stretches out, and waits with the state that big presser feet 21 cannot catch, and, at determining of needing Time control extract out motor 444 and extract out from peristome 111, make lining cloth S by big presser feet 21 Catch and carry out supplying (with reference to the T2 of Figure 16).

In this case, motor 444 is extracted out as can be to the state that can be supplied to and can not The actuator that the state of supply switches over works.

Additionally, in the case of the supply being carried out lining cloth S by said structure, at lining cloth S In the case of being soft quality or thin quality, sometimes lining cloth is sent into shifting from peristome 111 The downside of the big presser feet 21 of disorder of internal organs is difficult.

In the above cases, preferably rotatable around Y-axis in the configuration of the front side of peristome 111 The help roll that ground is supported, by height and the workbench of the upper end of the outer peripheral face of this help roll The height of the upper surface of 11 substantially equally configures.In this case, its periphery of help roll Face abuts with the lower surface of big presser feet 21 and produces driven, therefore, it is possible to will be from by help roll The downside of big presser feet 21 is sent in the end, front of the lining cloth S that peristome 111 is extracted out, it is possible to real The supply of the most suitable lining cloth S.

Alternatively, it is also possible to utilize configuration switch 65 that following control is switched over, it may be assumed that be set to Make the state that a part for the end, front of lining cloth S is stretched out from above-mentioned peristome 111, needing The timing constraint relief wanted and supply the control of lining cloth S；And the front end of above-mentioned lining cloth S Portion does not stretches out from peristome 111, is controlled extracting motor 444 out in the timing needed, Extract out from peristome 111, the control of supply lining cloth S.
