The specific embodiment
Followingly preferred implementation of the present invention is elaborated with reference to accompanying drawing.
Fig. 1 is to use the stereogram as the Sewing machines 30 of the sewing method of the ribbon of one embodiment of the present invention.Sewing machines 30 is ribbon feed mechanism 32 to be installed on as the sewing machine main body 31 of flat seam sewing machine and to be constituted, supply with rubber strip T as the ribbon of retractility in the present embodiment, for example under the situation of the rubber seam dress of opening circumferences such as waistline portion that carries out panties and sport pants etc. or huckle, use.
On the cylinder pedestal part 35 of sewing machine main body 31, flatly dispose needle plate 36, on needle plate 36, dispose foundary weight 37.37 of this foundary weight are supported on the sewing machine main body 31, and foundary weight 37 is by torsion spring (with reference to Fig. 2) 38 and by the application of force downwards.On the needle plate under the foundary weight 37 36, being formed with pin 39 (with reference to Fig. 2) inserts the logical pin portion (not shown) that falls, reaches at cloth (blank) throughput direction A and go up the delivery chute (not shown) that extends, in this delivery chute, be provided with and carry tooth (not shown), the elliptic motion that this conveying tooth freely haunts on synchronously carrying out on needle plate 36 with pumping of pin 39 in delivery chute is carried the blank on the needle plate 36 along cloth throughput direction A.And near the cloth throughput direction A of foundary weight 37 upstream side (right side of Fig. 2), the edge that the blank that will be carried is set cuts off and the knife system 40 (with reference to Fig. 2) of alignment.
In the front of sewing machine main body 31 ribbon feed mechanism 32 is installed.Ribbon feed mechanism 32 has: the supply unit 53 that (big roller 50 and pony roll 51) and knife system 52 is made of the donor rollers of ribbon; With stepping motor 55 as drive source.Be provided with above ribbon feed mechanism 32 rubber strip T to donor rollers 50, the 51 band transports of supplying with (not shown), to 50,51 conveying effect, rubber strip T is supplied with to needle downing position by above-mentioned donor rollers.
Fig. 2 is the side view of ribbon feed mechanism 32.Fig. 3 is the general profile chart that the cut-out upper thread III-III from Fig. 2 sees.Stepping motor 55 is maintained on the motor mounting platform 60, and motor mounting platform 60 is installed on the roller arrangement erecting bed 61 (omitting among Fig. 2 and Fig. 3).On the output shaft of stepping motor 55, be fixed with synchronous pulley, make synchronous pulley (all not shown) rotation by synchronous band.Synchronous pulley links by axle (not shown) and big roller 50.Thus, can rotate driving big roller 50 by stepping motor 55.51 of pony rolls are supported on the roller chain 62, and via torsion spring (not shown) and big roller 50 elasticity butts.And the operator in face of roller chain 62 is pulled up to, can make pony roll 51 leave from big roller 50 by pushing the roll-in bar (not shown) that links with roller chain 62.Therefore, when rubber strip T is set, under the state that pony roll 51 is left, with the gap of rubber strip T insertion with big roller 50, and with pony roll 51 repositions.
Therefore the outer peripheral face of big roller 50 and pony roll 51 has carried out annular knurl processing, by big roller 50 and pony roll 51 clamping rubber strip T reliably.And when big roller 50 rotation was driven, pony roll 51 driven rotations were sent downwards by the rubber strip T of big roller 50 and pony roll 51 clampings.
On the roller arrangement erecting bed 61 of ribbon feed mechanism 32, be provided with the belt sensor of realizing by fluorescence detectors such as optical choppers 56.Upstream side at the cloth throughput direction A of needle plate 36 is attached with reflecting plate 57.Reflecting plate 57 constitutes, and it is positioned on the light path of the light that sends from the light-emitting component 56a of belt sensor 56, and its reverberation points to the photo detector 56b of belt sensor 56.
Under big roller 50 and pony roll 51, knife system 52 is installed.Knife system 52 is made of dead knife 52A and movable blade 52B, and rubber strip T is sent medially by it, when stitching is finished, can cut off rubber strip T by making movable blade 52B action.Movable blade 52B is driven by cylinder (not shown).Be formed with ribbon guiding port 41 on foundary weight 37, the rubber strip T that sends by knife system 52 inserts ribbon guiding port 41, and be directed into foundary weight 37 below.
In the Sewing machines 30 that so constitutes, at the tubular blank to as shown in Figure 6 stitching object is opening circumference, for example waistline portion 71 of panties 70, during along its circumferencial direction stitching rubber strip T, when foundary weight 37 is risen, rubber strip T is supplied to ribbon guiding port 41, and waistline portion 71 is arranged on the cylinder pedestal part 35 of sewing machine main body 31 in the mode that the part of panties 70 is positioned under this band T.In addition, omitted the diagram of cylinder pedestal part 35 in Fig. 2 and Fig. 3, but represented panties 70 are arranged on state on the cylinder pedestal part 35, the waistline portion 71 of panties 70 is clamped between needle plate 36 and the foundary weight 37.And when the above-mentioned conveying tooth (not shown) that moves by not shown drive source moved, panties 70 were transferred in the mode in cloth throughput direction A cocycle.With this cloth carry action synchronously, pin 39 beginnings action up and down reciprocatingly, and donor rollers is to 50,51 actions, band T be directed into foundary weight 37 below, in the waistline portion 71 of panties 70, sew up rubber strip T.At this moment, knife system 40 also is a dissengaged positions, the edge 74 of the panties 70 carried is cut off and aligns.Make the feed speed of rubber strip T slightly littler than cloth transporting velocity, rubber strip T has in the waistline portion 71 that is stitched into panties 70 under the state of tension force thus.
In the stitching of rubber strip T, panties 70 are in order to cut off few width of trying one's best with blank end alignment and by knife system 40, and together are transferred with band T on one side by blank guider G guiding blank end 70E on one side.On the reflecting plate 57 of belt sensor 56 is arranged on above the leading section of blank guider G, therefore do not detect the blank end 70E of panties 70, and detect the stitching top Ts of portion of band.When the stitching top Ts of portion passed through on the reflecting plate 57 when the stitching of rubber strip T is carried out, the stitching end of rubber strip T centers on a week, photo detector 56b can't accept the reverberation of self-emission device 56a.Can't accept reverberation from detecting photo detector 56b, the stitching top Ts of portion that calculates rubber strip T arrives the time of above-mentioned ribbon guiding port 41, and stopping of carrying out that cloth carries and donor rollers are to 50,51 stop.That is, when sewing up the top Ts of portion arrival ribbon guiding port 41, become the stitching terminal part.Afterwards, stepping motor 55 counter-rotating is also reversed with this big roller 50, is endowed tensile force by the rubber strip T of big roller 50 and pony roll 51 clampings.The rubber strip T that panties 70 are finished with stitching is by needle plate 36 and foundary weight 37 clampings, so rubber strip T stretched by the opposite direction to the direction of the supply, becomes the state of elongation between this retained part and donor rollers are to 50,51.Knife system 52 actions under the state of this elongation, rubber strip T is cut off.Fig. 4 represents common stitching state, and Fig. 5 represents to sew up the state that rubber strip T is cut off after finishing.
Fig. 6 represents by above-mentioned Sewing machines 30 rubber strip T seam to be installed to the example of the panties on each opening circumference.The state of expression is in the panties 70 of Fig. 6, at the state in the waistline portion 71, after the cut-out of the stitching of rubber strip T and rubber strip T, on the left and right sides huckle 72,73, further excised the state of cut-out end (cut-out head part) after the cut-out of the stitching of rubber strip T and rubber strip T.The stitching of rubber strip T in waistline portion 71, while be mobile stitching of panties 70 circulations that makes as the tubular blank, the result sews up and carries out along a direction.
When the suturing part of rubber strip T becomes a week, carry out the cut-out of rubber strip T by knife system 52 as described above.When this cuts off, as shown in the figure, the cut-out end Te of residue rubber strip T on the terminal part of sewing up, it is cut and go out of use to cut off end Te afterwards.This cut-out end Te is cut off under elongation state as described above, is therefore cutting off after-contraction, and its length L s shortens significantly than the length L of the situation of Figure 11.Therefore, the quantitative change of cut and discarded rubber strip T is few, can save resource and cutting down cost effectively in the stitching factory of sewing up processing in a large number.
Fig. 7 is the control block diagram of Sewing machines 30.The stepping motor 55 of Sewing machines 30 by control part (control circuit) 63 control Sewing machines turning motors 64, ribbon feed mechanism 32, cut off the knife system 52 of rubber strip T movable blade driving cylinder (not shown), and cut off the knife system 40 that the edge portion of blank aligns.This control part 63 responds the signal S1～S4 that is imported and carries out these controls.Signal S1～S3 is from 65 outputs of the pedal operated by operator's underfooting, the signal S1 signal of entering into before being, and signal S2 is neutral signal, the signal S3 signal of entering into after being.And signal S4 has no signal from the blank that belt sensor 56 is exported.
Then, describe with reference to the sequential chart of the flow chart of Fig. 8 and Fig. 9 control action Sewing machines 30.Moment t0 among Fig. 9 represents that the stitching operation of last time finishes and set about next state when sewing up operation.Behind moment t1, pedal 65 quilts, enter into (step ST1), enter into signal S3 behind the control part 63 response pedals 65 and make foundary weight 37 become lifting position, and under this state, take out and sew up the panties of finishing 70, and the blank 70 that the next one is sewed up can be arranged on the needle plate 36.At this moment, stepping motor 55 is just changeing, and only supplies with the rubber strip T of scheduled volume, and rubber strip T is inserted into ribbon guiding port 41 (step ST2).During when the insertion of the setting of blank 70, rubber strip T and to the installation in precalculated position, moment t2 stop pedal 65 after enter into and turn back to the neutral position.Control part 63 response drops to down position from the neutral signal S2 of pedal 65 with foundary weight 37, thus on needle plate 36, overlaps under the state on the blank 70 foundary weight 37 at rubber strip T and pushes from above.
Then, at moment t3, the operator position (step ST3) of preceding entering into of entering into before with pedal 65, and begin to sew up operation.So the preceding signal S1 that enters into is transfused to control part 63, control part 63 responds these signals and makes 64 rotations of Sewing machines turning motor, driving Sewing machines, and makes the stepping motor 55 of ribbon feed mechanism 32 just change (step ST4).Thus, rubber strip T is supplied to blank 70, sews up rubber strip and be sent on blank 70.And knife system this moment (roll adjusting mechanism (メ ス De ロ Star プ)) 40 is in off-position, and when blank 70 was sent, the edge 74 of waistline portion 71 was cut off and aligns.
Like this, seam dress rubber strip T on the opening circumference (waistline portion) 71 of blank 70 when near sewing up when finishing, makes belt sensor 56 open and detect and have this situation of band edge at moment t4 as described above, and this signal S4 is transfused to control part 63 (step ST5).At this moment, knife system (roll adjusting mechanism) 40 actions (step ST6) stop the cut-out of 40 pairs of blanks 70 of knife system.Afterwards, at moment t5, when the operator stopped to enter into of pedal 65, the rotation of Sewing machines turning motor 64 and stepping motor 55 stopped, and the stitching operation of rubber strip T is finished.
At moment t6, when the operator carries out the post legged fashionable (step ST7) of pedal 65, control part 63 responses are entered into signal S3 after this and are made stepping motor 55 counter-rotatings.Thus, rubber strip T is by stretch to the opposite direction of the direction of the supply (step ST8).Simultaneously, sutural cut-out (step ST9) is carried out in thread cutting device (not shown) action.Then, control part 63 makes knife system 52 actions, will cut off owing to the rubber strip T that pull-up is extended, and makes foundary weight 37 become lifting position (step ST10).
By the cut-out of rubber strip T, finish the rubber strip of panties 70 and sew up operation, foundary weight 37 is in lifting position under this state, therefore can take out the panties 70 that stitching is as shown in Figure 6 finished.And, at moment t8, when the operator stop pedal 65 after enter into and when returning the neutral position (step ST11), control part 63 responds these neutrality signal S2 and makes knife system 40 become off-position (roll adjusting mechanism resets) (step ST12), and make foundary weight 37 become down position, and become the next holding state of sewing up action.Afterwards, new blank is set, the action of repeating step ST1～step ST12 is carried out the stitching of rubber strip T to the waistline portion 71 of panties 70.Stitching to the rubber strip T of the left and right sides huckle 72,73 of panties 70 is carried out similarly.Like this, finished the panties of sewing up 70, as shown in Figure 6, the cut-out end Te of rubber strip T shortens significantly than existing situation, and therefore, even sewing up the stitching factory of processing in a large number, the amount of the rubber strip T that goes out of use is also cut down significantly.And, not needing the change of the structure of existing sewing machine 30 itself, therefore can only implement by the change of operation program, extremely useful to the user.
In above-mentioned motion flow, enter into signal as triggering detect the pedal of (belt sensor unlatching) step ST7 afterwards with the band edge of step ST5 after, and the band pull-up of execution in step ST8 (band is carried the motor counter-rotating) and the band of step ST10 are afterwards sheared, but the invention is not restricted to this, for example also the counter of handling the needle can be set, to counting from the number of handling the needle that begins to stitch, counting out predetermined the handling the needle when several of finishing, send the reverse signal of stepping motor 55 and the actuating signal of knife system 52 to control part 63 corresponding to rubber seam dress.Perhaps, also the band edge of step ST5 can be detected (belt sensor unlatching) signal S4 as triggering, after the scheduled time warp after this signal S4 input, send the reverse signal of stepping motor 55 and the actuating signal of knife system 52.The scheduled time of this moment is, precomputes the Ts of rim end portion shown in Figure 3 and arrives the time till the suture location after the input of blank sensor signal S4 and set.
In addition, in the above-described embodiment, the sewing method with ribbon of the present invention is applicable to the example of flat seam sewing machine is illustrated, but applicable object also can be overlock machine.
And, after finishing as stitching, give method with the rightabout tensile force of the direction of the supply to ribbon, to donor rollers is described the example of counter-rotating, but also can constitute, donor rollers to and suture location between configuration give the device (for example press section of moving) of tension force to rubber strip by cylinder etc., and after stitching is finished, make this device action.
And belt sensor 56 is to detect the sensor whether band sew up on the opening circumference of blank passes through, but also can be that rubber strip is carried out the method that light detects to the overlap condition of blank.At this moment, in rubber seam dress way, be the state of only overlapping 1 layer of rubber strip on blank, when centering on a week in waistline portion, rubber strip becomes overlapping 2 layers state.Therefore, whether the light income the when light income in the time of can be according to 1 layer of rubber strip and overlapping 2 layers poor is judged that rubber strip is sewed up to finish.By this blank sensor, even operator's inoperation can be judged automatically that also rubber stitches dress and finishes, and carry out the pull-up and the cut-out of rubber strip.Being not limited to the sensor of illustrative smooth breaker mode as belt sensor 56, also can be the sensor of other modes.
And ribbon is not limited to rubber strip, also can be strap of suffering from retractility etc.
The present invention can implement by other variety of ways that do not break away from its spirit or principal character.Therefore, above-mentioned embodiment only is an illustration on any point, and the scope of the invention is a represented content in the patent request scope, is not subjected to any constraint of specification text.And the modification or the change that belong to patent request scope all belong in the scope of the invention.
