Description
The present invention relates to a kind of lockstitch button holder, especially the lockstitch button holder of using at raw material buttonhole portion periphery eyelet
The lockstitch button holder that buttonhole portion periphery eyelet is used on raw material or cloth was once developed in the past.
Lockstitch button holder has hello the cloth apparatus that cloth is moved on the Y of front and back direction, make pin drop to the fabric dividing device that is used for cutting cloth in the cloth buttonhole portion at the balancing point device of swinging on the directions X with the fabric dividing cutter.This machinery comes eyelet on the periphery of buttonhole portion with the combination of feeding cloth apparatus and balancing point device, and when eyelet with the fabric dividing buttonhole portion of lancinating out, make buttonhole thus.
Lockstitch button holder (abbreviating " machine " from now on as) is reinforced the seam B of portion, right parallel portion C and second around left parallel portion A, first and is reinforced the seam D of portion eyelet as shown in figure 26.(for example when the approaching termination of eyelet of portion C) drives the fabric dividing cutter it dropped on the F of buttonhole portion, thereby make buttonhole when the approaching termination of eyelet.
As a kind of eyelet pattern that goes out with traditional keyhole mechanism, " double slit pattern " eyelet that is known in the industry, traditional double slit pattern on around the above-mentioned buttonhole A of portion, B, C and D makes for twice stitching overlapping and make.
Because conventional machines severed buttonhole before the buttonhole pattern is just in time finished, the cloth cutting edge E (Figure 26) that is made by the fabric dividing cutter is not sewn in the stitching and is exposed in outside the stitching, makes outward appearance inferior.
In order to address this problem, known countermeasure is just buttonhole to be severed before buttonhole periphery eyelet.But this method also has the inferior shortcoming of the outward appearance of making.Buttonhole on cloth cutting edge not by eyelet the time can be fluttered, thereby makes stitching skip or make side seam lax sometimes.
In conventional machines, the stitching density of reinforcing seam portion is often than parallel portion height.But known double slit pattern still is that parallel portion all adopts stacked seam equally no matter reinforce seam portion when being made of.Therefore, can become too high so that profile is too swelled reinforcing stitching density in the seam portion, make the product appearance that is seamed into inferior, be worth and reduce.In addition, because pin will drop on the part of overpopulation, moving up and down of pin can make the line scratch, and regular meeting makes thread breakage.
In order to address the above problem, an object of the present invention is to provide a kind of lockstitch button holder, and this machine can make the improved outward appearance of side seam and cutting edge that fabric dividing is lancinated out exposes.Another object of the present invention is to provide a kind of control device so that obtain double slit pattern, the unwanted stacked seam of elimination that various appearances is improved to lockstitch button holder.
In order to address the above problem, the lockstitch button holder that first scheme of the present invention is provided has: be used for eyelet device, a control device that is used for cutting out the fabric dividing cutter of buttonhole on raw material and controls this machine like this at buttonhole periphery eyelet on the raw material, promptly detour two circles when coming eyelet buttonhole peripheral when the eyelet device, the fabric dividing cutter is driven as a means of cutting out buttonhole at the first lap of eyelet, encloses at second of eyelet then not to be driven.
Adopt first scheme of this machine, owing to severed at the second circle eyelet front buckle hole, therefore the fabric dividing cutter can be by eyelet in the second astragal mark at the cutting edge that forms on the raw material, and do not expose outside stitching, thereby can improved side seam outward appearance and do not expose cutting edge.In addition, owing to before cutting out buttonhole on the raw material, have the first lap stitching, therefore can access stable side seam.
Alternative plan of the present invention is on the basis of the lockstitch button holder of first scheme, make the eyelet device comprise that electronic Y direction is fed to drive unit and drive hello cloth mechanism in the Y direction so that be used for, feed to drive unit so that be used for electronic directions X in directions X driving hello cloth mechanism or needle vibrating mechanism, when feeding feed for drive unit and directions X to detour under the control to drive unit two to enclose the eyelet buttonhole in the Y direction, control device has CROSS CROTCH function and stacked joint function, the CROSS CROTCH function is needling position and the skew mutually of second circle that makes the first lap eyelet, thereby the eyelet route of first lap and second circle are intersected, stacked joint function is to make the needling position of the first and second circle eyelets near identical, thereby make the eyelet route of first lap overlapping with second circle basically, also have selecting arrangement then to can be used to select CROSS CROTCH function or stacked joint function.
Adopt the alternative plan of this machine, available selecting arrangement select stacked joint function in case obtain traditional double slit pattern or the CROSS CROTCH function so that form to intersect side seam, thereby can draw multiple eyelet pattern.
Here, the eyelet pattern that first or alternative plan of above-mentioned this machine is suitable for not only comprise with the shirts coupling, by parallel portion with reinforce the eyelet pattern that seam portion forms, but also comprise with coupling such as jeans, the eyelet pattern of radially extending from the center, end arranged at the two ends of buttonhole.
Third party's case of the present invention is on the basis of the lockstitch button holder of first scheme, its bight pattern has the parallel eyelet portion parallel with buttonhole and under the condition of the reinforcing seam portion at buttonhole two ends, allow control device have and make the function of reinforcing the seam attenuation, make reinforce seam portion when the first lap eyelet not by eyelet, and when the second circle eyelet just by eyelet device eyelet.
Adopt third party's case of this machine, double slit just is applied in the parallel eyelet portion that has than the low-density side seam, and be not applied in the reinforcing seam portion with higher density side seam, therefore this machine can provide high-quality side seam, prevents to produce in reinforcing seam portion the side seam that traditional double slit is understood the undue protuberance that produces.In addition, can prevent broken string, this is because frictional force is less on the line of eyelet.
Cubic case of the present invention is to increase selecting arrangement on the basis of the lockstitch button holder of third party's case so that be used for selecting making the function of reinforcing the seam attenuation or the eyelet function of when first and second enclose eyelets eyelet being reinforced seam portion.
Adopt the cubic case of this machine, make this machine select the traditional double slit or the pattern of attenuation for use in reinforcing seam portion, thereby obtain various eyelet patterns with selecting arrangement.

The explanation of label:
The 1-lockstitch button holder, 6-upper axis, 8-shank, the 9-pin, 14-cloth holding plate, 15-workpiece clamp, 16-fabric dividing cutter, 18-shank swing base portion, the 20-Y direction is fed to pulse motor (the Y direction is fed to drive unit), 40-baseline pulse motor (directions X is fed to drive unit), swing width pulse motor (directions X is fed to drive unit), 80-upper lines parting tool, 100-CPU (CPU, control device), 110-operation panel (selecting arrangement).
The explanation embodiments of the invention are consulted Fig. 1-3 earlier now.
Shown in Fig. 2 and 3, the lift pin mechanism that is used for making pin 9 to rise and descend comprises: upper axis 6, one stand lock seam motor 5 or pulse motor etc., and a crank cam 7.The rotation of eyelet motor 5 is transformed into moving up and down of shank 8 by crank cam 7, thereby pin 9 is moved up and down.Upper axis 6 is linked on the lower shaft 11 by a vertical axis 10, is respectively equipped with helical gear 10a and 10b at the two ends up and down of vertical axis 10, so as to driving a pawl 12 that is connected on the lower shaft 11.
The front view that Fig. 4 looks from the front for the needle vibrating mechanism of machine 1.Fig. 5 is an exemplary view of needle vibrating mechanism, is used for illustrating its operational circumstances.Fig. 6 is the operating sequence of needle vibrating mechanism; (a) state of the top bit of balancing point cam 54 in the baseline side is shown, the state of cam 54 top bit in cam swing width side (b) is shown.
The needle vibrating mechanism that pin 9 is swung on left and right directions has: one makes pin 9 is the main needle vibrating mechanism that initial point is swung left with the baseline, a swing width change mechanism and the baseline change mechanism that baseline is changed on left and right directions that is used for changing the pin swing width.
Shown in Fig. 3-6, main needle vibrating mechanism has: shank swing base portion 18, pin swing arm 49, connecting axle 48, connecting rod 47, needle swing cam lever 46, needle swing cam (triangular cam) 54, driving shaft 53 and reduction gearing 51,52.The rotation of upper axis 6 is sent to needle swing cam 54, thereby makes given width of needle swing cam lever 46 swings, and shank swing base portion 18 is just around pivot 18a swing, so pin 9 is just swung on left and right directions like this.In this example, when pin swing base portion 18 carried out oscillating motion, connecting axle 48, driving shaft 53 and pivot pin 44b all were fixed on its position.On the other hand, pivot pin 45a all rotatably is being connected relevant part with connecting pin 46a, and is being provided with movably.
The pin oscillating motion is synchronous with moving up and down of pin 9 by upper axis 6.When pin 9 when odd number time falls, 8 of shanks are on baseline; And when even number time shank 8 by swing and position in the baseline left side at a distance of a given swing width.
Fig. 7 shows the change of the baseline position of being carried out by the pin swing mechanism.Fig. 8 shows the change of the swing width of being carried out by the pin swing mechanism.
With regard to swing width changes mechanism, also can see from Fig. 8, the rotation of swing width motor 41 (pulse motor or analog) is by connecting rod 55 and 56, the pivot pin 44b that drives of adjustment cam lever 46 motions is moved towards the direction (being essentially left and right directions) that changes swing width, thereby change the swing width of pin 9.
With regard to baseline changes mechanism, from Fig. 7, also can see, when baseline changes motor 40 (pulse motor or analog) rotation, baseline arm 43 is swung around pivot 43a, the position that causes pivot pin 44b changes towards the direction (being essentially above-below direction) that changes the swing initial point, thus the baseline position when changing pin 9 swings.
That is to say, swing width motor 41 and baseline motor 40 constitute directions X and feed the drive unit of giving, because this two motor-driven needle vibrating mechanism just can make shank 8 swing on left and right directions.
Fig. 9 is the perspective view of fabric dividing mechanism (fabric dividing device), and wherein buttonhole is to move down fabric dividing to lancinate to wear the cloth and form on the buttonhole position of cloth.Fabric dividing mechanism has: the dress knife plate 31 that fabric dividing cutter 16 is contained in its lower end, be used for driving the activation lever 35 that dress knife plate 31 moves up and down around pivot 35a rotation, link the cutter actuating arm 36 that can transmit its rotation and always move up and down at a high speed with upper axis 6 at the one end, be provided with to such an extent that can engage so that the cutter that sends moving up and down of actuating arm 36 to activation lever 35 drives drag hook 37, and be used at the solenoid 75 that drives control connection between drag hook 37 and the actuating arm 36 or disengaging with cutter actuating arm 36.
The plunger 75a of solenoid 75 is usually pushed outwards to be gone out so that make and drive drag hook 37 and leave from actuating arm 36, and fabric dividing cutter 16 rests on its upper position at that time.When instruction according to the driving cutter, when plunger 75a was retreated, because the pulling function of spring 37b, the engagement recess portion 37a that drives on the drag hook 37 engaged with actuating arm 36, moving up and down of actuating arm 36 is sent on driving drag hook 37 and the actuating arm 35, thereby dress knife plate 31 moves down.

Adopt said structure, but machine 1 by slave plate 110 accept various setting datas, calculate will by the eyelet pattern of eyelet, control and drive machines 1 just eyelet go out various bight patterns.
The project that will set on operation panel 110 at first is described now.Figure 12 is will be from the repertory of operation panel 110 inputs.Figure 13 is the diagram that the length parameter of eyelet pattern various piece is shown.
Comprise from the setting data of operation panel 110 inputs: pattern is selected length data (consulting Figure 13) as " fabric dividing length " (a), " cutter wide (b) ", " add all suture mark length " (c), " reinforced suture stitch width " (d), " parallel portion pitch " (e), " reinforced suture mark pitch " (f), " fabric dividing cutter-first time seam portion at interval " admittedly (g), " fabric dividing cutter-second reinforce seam portion at interval " (h), and " cutter descends left; right position " data that specify in the displacement of left and right directions upper slitter down position; Specify the corrected value of VCM 60 so that be used for " active tension correction " data of tension force of adjustment of tonicity device 19; Comprise " parallel portion tension force ", " reinforcing seam portion tension force ", " tension force when eyelet begins ", " tension force when eyelet stops " and " tension force when line cuts off " at the tension data of this eyelet predetermined instant respectively; " fabric dividing cutter size " data (L
1), " workpiece clamp size " data, the data of " conversion of single seam/double slit ", " selection of double slit ", " first lap is reinforced the attenuation of seam ", under the situation of double slit " driving of cutter during first lap ", when beginning, eyelet is used for specifying " the feeding when eyelet begins " of feeding, " machine speed during the cutter driving " that when eyelet begins, is used for specifying " baseline position when eyelet begins " of baseline position (reference position of needle vibrating mechanism) and when driving fabric dividing cutter 16, indicates machine speed to the position to the position.
In the project that sets, item number 18 to 21, i.e. " conversion of single seam/double slit ", " selection of double slit ", " reinforcing the attenuation of seam during first lap ", all relevant with " driving of cutter during first lap " these four with the present invention.
In project " in the conversion of single seam/double slit ", " 1 " or " 2 " refers to select single stitching or double slit respectively.In project " in the selection of double slit ", " 0 " or " 1 " is chosen in stacked seam or the CROSS CROTCH function in the double slit respectively.On project " first lap is reinforced the attenuation of seam ", " 1 " or " 0 " refers to reinforce the attenuation function of seam respectively or two astragal marks in the reinforcing seam portion are double slit.On project " driving of first lap cutter ", " 0 " or " 1 " selects cutter respectively is to be driven or not to be driven when the first lap eyelet.
When operating machines 1 the time, the operator at first carries out input process, with setting data alter operation board 110.Because each setting item all can have predefined improper value or import in advance in memory data, the operator can only import the data of required change.
The scope that is set of its of each setting item oneself, this scope can be used to check the data of input, and whether whether data can be distinguished in this scope wrong.
A plurality of setting data groups can number be registered by each eyelet pattern.The operator selects pattern number just can read corresponding setting data group like this, so that the eyelet of control regulation pattern.
Behind the input setting data, the workpiece raw material is set on the machine 1, be enabled in the eyelet key 131 on the operation panel 110, its timed unit is just according to input data computation eyelet pattern.Figure 14 and 15 a series of views for the eyelet pattern that goes out according to the eyelet order computation.
If " conversion of single seam/double slit " is selected as " 2 ", " double slit selection " is " 1 ", and " first lap is reinforced the attenuation of seam " is " 1 ", the CROSS CROTCH and the function of reinforcing the seam attenuation just can work so, thus in just can draw in order Figure 14 and 15 with add circle 1 to 14 shown in pattern.
The CROSS CROTCH function on left and right parallel portion A and C (Figure 26) make the side seam and the second circle pattern that cross one another and form of first lap eyelet.With regard to the CROSS CROTCH function on the parallel portion A, for example, the side seam P of first lap eyelet
2-P
3(among Figure 14 add circle 2) with second the circle eyelet side seam P
7-P
8(among Figure 14 add circle 7) intersect, wherein when the second circle eyelet begins, have the stitching of a displacement not have cloth to feed and give (dotted line mark), P
6-P
7(add among Figure 14 circle 6).Eyelet on right parallel portion C carries out in the mode identical with parallel portion A.
The function of reinforcing the seam attenuation is reinforced first and second and is only applied the second circle reinforced suture mark on seam B of portion and the D and do not apply the first lap stitching and reach.For example the reinforcing of the attenuation on part B seam is to shift stitching P by first lap
3-P
4(transfer to portion C from part A, add among Figure 14 circle 3) and the second circle reinforced suture mark P
9-P
10(add among Figure 15 circle 9) forms.Second reinforces the seam D of portion with the mode eyelet identical with part B.
Shift stitching be achieved in that as add among Figure 14 circle 3 shown in, as end points P from part A
3The later cloth of two stitchings that set out eyelet in part B just stops to feed to be given, and the balancing point baseline is displaced on the position of eyelet portion C, so just at eyelet starting point P
4Carry out eyelet, cloth is turned around to feed on the Y direction and is given.Transfer stitching (P from right parallel portion C to left parallel portion A
5-P
6, among Figure 14 add circle 5) will carry out in an identical manner.In Figure 14, add circle 3 and 5 in, white point representative is at the following pin mark of baseline side.
If in setting item " selection of double slit ", specify and select " 0 " for use, will carry out stacked joint function so; At that time on the second circle eyelet starting point of parallel portion A (among Figure 14 add circle 6) because above-mentioned dotted line stitching is eliminated, the side seam of the side seam of first lap and second circle almost is stacked on the same line.
In input operation, not have will " first lap be reinforced the attenuation of seam " when being chosen as " 0 " when the function of reinforcing the seam attenuation, the pattern that should carry out common reinforced suture mark calculate and omit in Figure 14, add circle 3 on the calculating of the above-mentioned transfer stitching pattern shown in 5.
The calculating that will carry out fabric dividing cutter driving timing after the eyelet pattern calculates is as a means of driving fabric dividing cutter 16.If " driving of first lap fabric dividing cutter " is designated as " 0 ", should make providing regularly in the second circle eyelet so, if be designated as " 1 ", should calculate the timing ga(u)ge in the first lap eyelet so.
These computational processes will describe in detail in the back.
After the calculating of finishing the eyelet pattern, just can by the Y direction being fed the control of feeding pin 9 to motor 40 and balancing point width motor 41 be descended according to the coordinate that calculates to motor 20, baseline, so just can carry out the eyelet of buttonhole.At that time, in the timing that calculates, the fabric dividing cutter descends and severs a buttonhole seam, thereby forms buttonhole.
In last process, upper lines is cut off by upper lines cutter 80, and lower line is cut off by the cutter under the needle plate, thereby finishes the one-period of bight.
Detailed description now comprises the order of the inclusive process of above-mentioned double slit pattern that the control device of machine 1 is performed.Figure 16 is the general flow chart that the keyhole procedural order is shown.This keyhole process for example is that the starting from machine 1 begins.
When machine 1 was started, the subprogram of operation panel assignment procedure was performed at work step S1.If at work step S2, eyelet key 131 is opened (ON), and process enters work step S3 so, if not, work step S1 just turns back.Work step S1 and S2 carry out can importing all setting datas shown in Figure 12 during this period repeatedly till the eyelet key 131 on the plate 110 is depressed.
At work step S3, the subprogram of setting up the eyelet data is performed, and calculates the driving timing of eyelet pattern and fabric dividing cutter according to the setting data of input.At work step S4, for example from RAM 102 reading error marks, if there is any error flag(s) to go on record in the former work step, this process just stops at work step S5 so, and corresponding error is indicated the display part of delivering on the plate 110 140, if not, enter work step S6.
At work step S6, the signal of decline workpiece clamp 15 is outputed on the workpiece clamp solenoid driver 121.Then at work step S7, according to feed feed for initial point sensor 26, baseline to give from the Y direction initial point sensor 57 and balancing point initial point sensor 58 respectively to the Y direction feed give motor 20, baseline hello to the output of every motion detection of motor 40 and balancing point width motor 41, each initial point of detection hello cloth mechanism and needle vibrating mechanism.At work step S8, pin 9 is moved to first needling position, drive motors 20,40 and 41.
At work step S9, the signal that promotes workpiece clamp 15 is outputed on the workpiece clamp solenoid driver 121.If at work step S10, eyelet key 131 really belongs to opens (ON), and process enters work step S11 so, and as being shutoff (OFF), work step S1 so just turns back.At work step S11, workpiece clamp switch 124 is sensed, if at ON, process enters work step S12 so, if at OFF, the work step S10 that turns back so so repeats.Workpiece clamp switch 124 be transferred to open after, detect with sense switch under the workpiece clamp 28 at work step S12, if workpiece clamp 15 is the position above it, providing signal at work step S13 so descends workpiece clamp 15, if workpiece clamp 15 has been lowered by, workpiece clamp 15 is risen and makes the process work step S10 that turns back in work step S14 output signal so.
If at work step S15, workpiece clamp switch 124 is confirmed as opening (ON), and process moves on to work step S16 so, if turn-off (OFF), is raised in work step S14 workpiece clamp 15 so.If at work step S16, starting switch 125 is for opening to cause eyelet to begin, and process enters S17 so, if switch 125 is OFF, work step S15 then turns back.
At work step S17, carry out the eyelet process according to the eyelet data that the process of setting up in the eyelet data of work step S3 is set up, the eyelet process comprises the eyelet of a buttonhole from beginning to stopping, together with driven eyelet motor 5, the driving of fabric dividing cutter 16, and in the adjusting of the yarn tension of each eyelet timing setting on tensioner 19.
At work step 18, the error flag(s) that is write down the work step before RAM 102 reads out in for example, if without any error, process can enter next work step S19 so, if find to have any point mistake, process is just stopped at work step S20, and corresponding error is indicated on the display part 140 of plate 110.
At work step S19, by predefined value is signaled to active tension driver 120, the tension force that cuts off line is endowed tensioner 19.
Carry out lines at work step 21 to cut off/process that workpiece clamp promotes, line is cut off, promote workpiece clamp 15 then with thread cutter 80.
When the top position of workpiece clamp 15 when work step S22 is detected by sense switch under the workpiece clamp 28, at work step S23, because the action of active tension driver 120, line tension device 19 is released.After this process work step S10 that turns back, and repeat.
Figure 17 is for setting up the subprogram of eyelet data according to the work step S3 in the main-process stream of Figure 16.At first, will compare with the setting range (seeing Figure 12) that is stored in the ROM 101 at the setting data of last work step S1 input at the S31 of the Ministry of worker.If the input data are outside this scope, an error flag(s) just is set in the RAM 102 so.If find that at work step 32 any point error is arranged, this subprogram just is moved to end and turns back to main-process stream so.If do not find any error at work step S32, process just enters work step S33 so, calculates the eyelet pattern, enters work step S34 then, calculates the driving timing of fabric dividing cutter 16, and stops this subprogram.
Figure 18 is a flow chart of setting up the subprogram of the work step S33 calculating pattern in the process in the eyelet data.
At work step S41, the input data according to being stored in work step S1 input in the RAM 102 comprise " eyelet begins to feed to the position " and " eyelet begins baseline position ", calculate from first needling position to the left parallel portion (P Figure 14
1-P
2) the coordinate position of initial several stitchings of starting point.
According to the title of input data, " conversion of single/double slit ", " double slit selection " and " first lap is reinforced the attenuation of seam " are selected suitable branch respectively for use in work step S42, S43, S44, S45.
When regulation is not used double slit, can carry out computational process at work step S46.Use double slit if specify, stacked seam and normal seam, the so optional computational process that is used in work step S47 and S48 of reinforcing; If appointment is the reinforcing seam of double slit, stacked seam and attenuation, use work step S49 and S50 so, if double slit, CROSS CROTCH and the normal seam of reinforcing are used work step S51 and S52 so; And if the reinforcing of double slit, CROSS CROTCH and attenuation seam is used work step S53 and S54 so.After respectively this computational process was finished, this subprogram just finished and is transferred to the eyelet data to set up next work step (Figure 17) in the process.
In general, computational process A (at work step S46, S47, S48, S50 and S51) is corresponding to common buttonhole side seam, computational process B (at work step S49 and S53) is corresponding to the buttonhole side seam of not reinforcing seam, and computational process C (at work step S52 and S54) is corresponding to there being a stitching to be offset with respect to the side seam among the process A in the buttonhole side seam.Provide the detailed description of these calculating below.
Figure 19 is the flow chart of computational process A in pattern computational process.
At first, at the calculating work step S61 of left parallel portion,, calculate balancing point baseline position " a1 " (the some P among Figure 14 according to input data at work step S1
2), balancing point width (d-b)/2 (seeing Figure 13) and feed to give pitch " e " (its value is that length with left parallel portion is divided by a certain integer).
After this, calculate baseline position " a2 " (the some P9 among Figure 15), reinforced suture stitch width " d " and feed and give nodal point separation " f " (its value is that reinforcing is stitched minister's degree divided by a certain integer) at the first calculating work step S62 that reinforces seam portion.At the work step S63 of right parallel portion, calculate baseline position " a3 " (the some P4 among Figure 14), width (d-b)/2 and pitch " e ".Work step S64 in the second reinforcing seam portion calculates baseline position " a4 " (the some P13 among Figure 15), width " d " and pitch " f ".Stop calculating work step S65 at eyelet, with each several part is that left parallel portion, the first reinforcing seam portion, right parallel portion and second stitch of reinforcing seam portion are all added up as total stitch, and the stitch of each part all is to feed divided by it with the length of this part to calculate to pitch.
Adopt this computational process A just can calculate a circle stitch of common buttonhole.
Figure 20 is the flow chart of the computational process B in pattern computational process.At work step S71, carry out with in the same calculating of work step S61.Carry out the calculating of " a2 " in addition respectively at work step S72, work step S73 carry out with in the same calculating of work step S63, carry out the calculating of " a4 " at work step S74.
Adopt this computational process B just can calculate a circle stitch without the buttonhole side seam of reinforced suture mark.
Figure 21 is the flow chart of the computational process C in pattern computational process.At first the motion of carrying out pulse motor at work step S81 is the calculating of a stitching of 0, calculate do not drive the Y direction feed a stitching to motor 20 (among Figure 14 add circle 6 in P6-P7).Next, work step S82 carry out with in the same calculating of work step S61, work step S83 carry out with in the same calculating of work step S62.Secondly the motion of carrying out pulse motor at work step S84 is the calculating of a stitching of 0, calculate do not drive the Y direction feed a stitching of the pulse motor 20 give and other motor in needle vibrating mechanism (among Figure 15 add circle 12 in P12-P13), in addition work step S85 carry out with in the same calculating of work step S63, work step S86 carry out with in the same calculating of work step S64, and work step S87 carry out with in the same calculating of work step S65.
Adopt this computational process C just can calculate a circle buttonhole side seam, wherein have a stitching to be offset with respect to the side seam among the process A.
According to the pattern computational process of Figure 18 said process A, B and C are combined and just can calculate the eyelet pattern of appointment by the setting data of input.For example will just can calculate such eyelet pattern at the process B of work step S49 and in the process A of work step S50 combination, promptly the first lap side seam and the second circle side seam (stacked stitching) are identical on parallel portion, and just first lap reinforced suture mark is by attenuation.
Figure 22 is for setting up the flow chart of the practiced cutter driving timing of the work step S34 counting subroutine in the process in the eyelet data of Figure 17.Figure 23 is the parameter list that is used for the cutter driving stitch Mn of this calculating.
The cutter that this cutter driving timing computational process can be calculated cutter 16 drives frequency n and drives stitch " M1-Mn " (seeing Figure 23) corresponding to the cutter of number of times " 1-n ".
At first at work step S101, selected by setting data " conversion of single/double slit " is single stitching or double slit.At the work step S102 that double slit is used, if setting data " driving of first lap cutter " specifies first lap to drive, process just forwards work step S104 to, if specify second circle to drive, then forwards work step S105 to.
If use single stitching in that work step S101 is selected, be used in the parameter " M " that the stitch up to right parallel portion starting point that the pattern computational process of Figure 18 calculates substitutes work step S103 so.If be transferred to work step S104, use so until the stitch of the first lap starting point (P4 among Figure 14) of right parallel portion substitutes parameter M by S101 and S102.If forward work step S105 to, substitute parameter M with second stitch that encloses starting point (P10 among Figure 15) so up to right parallel portion.
After this, according to the input data " fabric dividing length " (a) and " fabric dividing cutter size " (L1),, after S113, calculate cutter 16 and sever necessary driving number of times of buttonhole length (a) " n " and until the driving stitch M1-Mn of the cutter 16 of the n time cutter driving at work step S106.That is exactly, and when stitch reached from several M1-Mn that eyelet begins to count, fabric dividing cutter 16 was driven.
In other words, at work step S101-S105, behind the stitch of the first lap that substitutes right parallel portion with parameter M or the second circle eyelet starting point, take the process route identical with work step S106-S113, according to this cutter driving timing computational process, can calculate the stitch of cutter 16 in the first lap or the second circle eyelet decline.
Figure 24 is the flow chart of the eyelet procedure subprogram of the work step S17 in the main-process stream of Figure 16.
This eyelet process begins at work step S131, total stitch of calculating in pattern computational process is designated as " residue stitch parameter " at that time, export starting-up signal so that drive eyelet motor 5 at work step S132 then, whether then move to work step S133 this machine for confirmation at rotation status.If in rotation, program moves to work step S134 so, if not rotation, program repeats until state is changed into rotation so.After this, repeat process step S134 to S141 so that carry out actual eyelet process until shut down.
At work step S134, the rotation of this machine is monitored, and process will stop when shutting down.
When according to the TG generator 118 that tests the speed, when the anglec of rotation of upper axis 6 reaches predetermined angle at work step S135, process enters work step S136, and needling position is fed by the Y direction according to the eyelet pattern of calculating and moved to motor 20, baseline motor 40 and swing width motor 40 at that time.Promptly actual eyelet eyelet pattern is according to the rules fed to cloth in the process of work step S135 and S136.
At work step S137, when the upper sensor 116 of pin detected shank 8 and rises to above given position, process moved to work step S138, and the needle tracking number is counted at that time, when this needle tracking number reaches the driving process of carrying out fabric dividing cutter 16 when driving needle tracking number " M1 " ~ " Mn ".
If at work step S139, when need feed blocking-up to benchmark feed for the requirement of reference position sensor 117, process moves to work step S140 so, so as execution hello to the assignment procedure on the reference position.At last at work step S141, when stitch and cutter drive the driving of number of times affirmation cutter 16 when consistent.
Embodiment according to above-mentioned machine 1 control device, because fabric dividing cutter 16 is to select " 1 " in setup parameter " driving of first lap cutter ", thereby be driven during the first lap eyelet before the second circle eyelet and cut out buttonhole, therefore the cutting edge of the cloth that is formed by the fabric dividing cutter can be by eyelet in the second astragal mark, and be not exposed to outside the stitching, thereby the outward appearance of side seam is improved.
In setup parameter " double slit selection ", select " 0 ", can obtain the function of CROSS CROTCH, wherein the second circle side seam is intersected with the first lap side seam, with traditional, enclose the double slit pattern that side seam is stacked on the first lap side seam with second and compare, can obtain better side seam pattern.In addition, this CROSS CROTCH just is applied on the significant parallel portion of outward appearance, thereby can reduce eyelet cycle time and stitch.
Moreover the intersection stitching function of the stacked joint function of traditional double slit pattern and formation intersection side seam can be selected by the selection of setup parameter " double slit selection ", thereby can obtain multiple eyelet pattern.
In setup parameter " first lap is reinforced the attenuation of seam ", specify " 1 ", just can only dual needle tracking be applied in the parallel eyelet portion with low-density side seam and not be applied in the reinforcing seam portion with high density side seam, therefore this machine can provide high-quality side seam, and prevents the side seam of the undue protuberance that traditional double slit is common in reinforcing seam portion.In addition, this machine makes us select common double slit for use or at the attenuation pattern of reinforcing seam portion by the selection of " first lap reinforce seam attenuation ", thereby can obtain multiple eyelet pattern.
The present invention is not limited in the control device of above-mentioned machine 1.For example, feeding cloth and can replace the balancing point that illustrates among the embodiment on directions X with feeding to cloth.In explanation, adopt pulse motor as drive unit, but servomotor or analog also can use.With regard to eyelet pattern speech, the present invention can be applicable to a kind of like this pattern, and wherein each is reinforced seam portion and all uses and bring out the radially stitching of sending out from buttonhole and come eyelet.Also available other variations in the double slit process.
Figure 25 illustrates the flow chart of another example of buttonhole process.
With regard to double slit process speech, the double slit eyelet carries out according to double slit result of calculation in the foregoing description.But also can use process as shown in figure 25, promptly at work step S201, finish the first lap eyelet after, if determine to adopt double slit at work step S202, process can enter S203 so, so that realize the second circle eyelet, do not do if behave like this, the eyelet process can stop at this point so.Afterwards,, workpiece clamp 15 can be risen, finish whole buttonhole process at work step S204.
