[pin pendulum-type sample]
In electronic sawtooth Sewing machines of the present invention,, straight line needle tracking, 2 zigzag, 3 zigzag, 4 zigzag, crescent, stowing needle tracking, customization style are arranged as pin pendulum-type sample.Shown in Fig. 5 (A), the straight line needle tracking is not carry out pin pendulum but carry out the style of straight line needle tracking seam at baseline position, so pin amplitude of oscillation degree (NW) is zero.Shown in Fig. 5 (D), 2 zigzag are to be that the benchmark 1 pin amplitude of oscillation falls within left and right stitch at 2 by the pin amplitude of oscillation (NW) pin with the baseline.Shown in Fig. 5 (E), 3 zigzag are, and to be the benchmark 1 pin amplitude of oscillation with the baseline fall within a left side, center, right 3 stitch by 1/2nd pins of the pin amplitude of oscillation (NW).Shown in Fig. 5 (F), 4 zigzag are, and to be the benchmark 1 pin amplitude of oscillation with the baseline fall within a left side, center 2 points, right totally 4 stitch by 1/3rd pins of the pin amplitude of oscillation (NW).
Shown in Fig. 5 (B), crescent is the selenodont style needle tracking of making by 12 pins or 24 pins in two circular arcs, and [standard crescent equalization] three kinds according to the kind of handling the needle, arranged.In addition, the direction at circular arc is a left and right sides crescent.About be defined as, the inboard of Sewing machines is right, the dome upside is positioned at the inboard, at this moment, is called right crescent, otherwise, then be called left crescent.Shown in Fig. 5 (C), stowing is a kind of like this stitch, that is, make and begin to carry out straight line seam, carries out the pin pendulum at last 2 pins of the pin number of handling the needle by the pin amplitude of oscillation (NW), and last 1 pin returns original position, and this style is carried out repeatedly.At this moment, carry out left and right stowing according to pin pendulum direction.Right (left side) stowing needle tracking is pin is put right side (left side) from the straight line needle tracking a style.Have, the customization style is the original style of making arbitrarily again.
[inherent data]
In each above-mentioned pin pendulum-type sample, have the pin amplitude of oscillation (NW), baseline position (NP), baseline reference position (NPs), needle tracking starting position (NS), needle tracking final position (NE), these inherent datas of pin number (NC).
The pin amplitude of oscillation (NW) is represented the pin amplitude of oscillation degree in each pin pendulum-type sample.For example, shown in Fig. 6 (A), the 1 pin width of cloth (NWS) is 1/3 of the pin amplitude of oscillation (NW) during 4 zigzag.That is, NWS=NW/3.At this moment, when drawing remainder in the partition value, be that equalization is distributed about benchmark with pin amplitude of oscillation degree center.NW is 5.0 o'clock, and NWS=1.6 surpluss 0.2.Therefore, initial 1 stitch is that 1.7, the 2 stitch are that 1.6, the 3 stitch are 1.7, and each stitch is followed successively by 1.7,1.6 when returning, 1.7.In addition, for example, the pin amplitude of oscillation degree during crescent is the style amplitude, in the pin pendulum, uses needle-swing data, and needle-swing data is stipulated by the center five equilibrium.According to style, have 24 pins, 12 pin data, (NW * NDn/8.2) formula carries out the position calculation of handling the needle, and wherein, NDn is the data of handling the needle, and NDp is the position of handling the needle, and NP is a baseline position according to NDp=NP+.
Shown in Fig. 6 (B), baseline position (NP) can be meant the pin pendulum basic point position of putting for the pin in [-] (left side) for [+] (right side), its opposition side for [0], Sewing machines inboard with the center of Sewing needles swinging mechanism.In scope-5.0～0～+ 5.0 that are no more than large needle amplitude of oscillation degree (WPx), set.
Shown in Fig. 6 (C), baseline reference position when baseline reference position (NPs) expression pin pendulum can be set branch right-hand member benchmark pendulum left end benchmark pendulum such as [] center references for, initial setting is configured to the center reference five equilibrium, for baseline position (NP), specifies the swing benchmark on the right left side of central authorities.For example, in 2 zigzag, baseline position (NP)=0.0, the pin amplitude of oscillation (NW)=3.0, during baseline reference position (NPs)=left side, pin is swung between 0.0～3.0.
Shown in Fig. 7 (A), withdrawal of needle position (NS) is meant in that [right left 1 side is specified the withdrawal of needle position after being connected on trimming, and initial setting is left withdrawal of needle.Have again, in crescent, stowing needle tracking, though about having, still, when right crescent, right stowing, left withdrawal of needle place has just become the position of withdrawal of needle.
Pin number (NC) is meant the pin number of crescent, stowing needle tracking, and when crescent was made, standard was 24 pins, and crescent also is 24 pins, and equalization is 12 pins and 24 pins, and the stowing needle tracking is set between 3～250 pins.Initial setting is, when crescent was made, standard crescent equalization was 24 pins, and the stowing needle tracking is 4 pins.
In addition, pin pendulum-type sample begin or when stopping formed eyelet style (being also referred to as intensive seam style) be effective to straight line needle tracking, 2 zigzag, 3 zigzag, 4 zigzag, each styles of crescent.The number of times of intensive seam, carries out with style unit to being returned as 1 style from withdrawal of needle, and can be set in the pin number is in 19 pins.In addition, the intensive seam cloth feed amount in intensive when seam is set dial 7 by intensive seam cloth feed amount and is set.For example, when 4 zigzag, shown in Fig. 7 (B), can be 6 styles, 3 pins are arranged in one+style, thereby the pin number is 18.
In addition, set as the selection of eyelet (intensive seam), following method is arranged: first method is meant that all styles of that adopts so-called pin pendulum-type sample carries out the method for eyelet; Second method is meant as the customization of eyelet and sets that the pin amplitude of oscillation that narrows down degree is set the pin number in the pin amplitude of oscillation (NW), the method that the middle pin of handling the needle in the pin amplitude of oscillation (NW) is swung in the same direction; The third method is meant the method that adopts eyelet customization style (original style).
The different eyelet styles of first kind of so-called pin pendulum-type sample of employing are carried out the method for eyelet, except so-called pin pendulum-type sample, every beginning eyelet, termination eyelet, set eyelet style (PC), the pin amplitude of oscillation (CW), intensive seam number of times (CC), and baseline position (NP), baseline reference position (NPs), needle tracking starting position (NS) are identical with pin pendulum-type sample.For example, shown in Fig. 7 (c), if be that 4 points, pin pendulum-type sample are 2 points, to stop the eyelet style be that 3 zigzag are that example describes with beginning eyelet style, then beginning the eyelet style is 4 zigzag, and the pin amplitude of oscillation is that CW1, intensive seam number of times are 3 times.Continuous pin pendulum-type sample is 2 zigzag in this eyelet, in this case, the beginning eyelet finishes the back according to pin pendulum-type sample, needn't resemble will determine under the situation of starting position 2～4 zigzag, arranges initial point from the pin that approaches the eyelet end position and carries out the pin pendulum.In addition, under the inconsistent situation of beginning of end position that begins the eyelet style and pin pendulum-type sample, after eyelet is over, give the restriction of the speed between a pin.Stopping the eyelet style is 3 zigzag, and pin amplitude of oscillation degree is CW2, and intensive seam number of times is 4 times.Stop in the eyelet at this, move on on the termination eyelet style, need add a pin, so intensive seam number of times+1 pin is intensive suture needle number just from pin pendulum-type sample.
Second method below is described, customization is set as second kind of eyelet, and the pin amplitude of oscillation that narrows down in the pin amplitude of oscillation (NW) degree is set the pin number, in the handling the needle in pin amplitude of oscillation degree (NW) pin is swung in the same direction.Set according to this customization, each is begun eyelet and stop eyelet can set the beginning close needle gage width of intensive seam (CPs), beginning intensive seam close needle gage pin number (CNs), stop the close needle gage width of intensive seam (CPe), stop intensive seam close needle gage pin number (CNe).Close needle gage * close needle gage pin number〉when the pin amplitude of oscillation is spent, can't set.
When the eyelet style is 2 zigzag, the pin amplitude of oscillation is deducted the divide a word with a hyphen at the end of a line pin amplitude of oscillation degree (N1) of close needle gage action pin pendulum amount as common pin pendulum and close needle gage pin pendulum.The pin amplitude of oscillation of dividing a word with a hyphen at the end of a line degree (the N1)=pin amplitude of oscillation (NW)-Mi needle gage (CP
*) * close needle gage pin number (CN
*).When the eyelet style was 3 zigzag, if the pin amplitude of oscillation deducted close needle gage start pin pendulum amount less than the 1 pin pin amplitude of oscillation (NTs), just as dividing a word with a hyphen at the end of a line pin amplitude of oscillation degree (NTe).When being 3 zigzag, if the pin amplitude of oscillation deducts close needle gage action pin pendulum amount greater than the 1 pin pin amplitude of oscillation (NWs), just the pin amplitude of oscillation after the deduction 1 pin pin amplitude of oscillation part as the pin amplitude of oscillation degree (NI) of dividing a word with a hyphen at the end of a line, control successively that close needle gage is regulated, the pin of dividing a word with a hyphen at the end of a line pendulum, 1 pin pin put.4 zigzag also-sample, when deducting remainder (NN) behind the close needle gage width of cloth, removing the remainder of NN gained as the pin amplitude of oscillation degree (N1) of dividing a word with a hyphen at the end of a line, the pin number (NCn) of its quotient as the 1 pin pin amplitude of oscillation with the 1 pin pin amplitude of oscillation greater than the 1 pin pin amplitude of oscillation.Intensive suture needle number is to deduct the remaining pin number in [the close needle gage pin number+pin number of dividing a word with a hyphen at the end of a line+residue style pin number] back, and pin pendulum-type sample becomes the number of times of available this pin number.The style of implementing close needle gage also is calculated as a style.
Fig. 8 illustrates the beginning eyelet needle tracking of 3 styles for example.
[setting of eyelet needle tracking style]
Below the establishing method of beginning (termination) eyelet style is explained.
Be used to set the flow process of beginning eyelet style shown in Fig. 9.In step S1, whether configuration switch of decision operation dish 10 (SW) 41 and detailed configuration switch 59 are connected simultaneously.When connecting simultaneously, set LED59a lamp bright (step S2) in detail.In step S3, beginning eyelet switch 42 1 is connected, and the LED42a lamp is bright, shows eyelet style numbering among the n segment display n 64d of display 64.In display 48, the eyelet style is numbered at 1～3 o'clock, shows pin amplitude of oscillation degree (step S4).
In Figure 13, show style numbering and its eyelet style that display 64 shows.Style numbering [0] expression and the identical style of pin pendulum-type sample also are the styles identical with the amplitude of fluctuation of saw-tooth stitch.Style numbering [1]～[4] are respectively 2 zigzag, 3 zigzag, 4 zigzag, straight line needle tracking style.Style numbering [5]～[9] are the customization styles (original style) as aforementioned the third eyelet.At this moment, the n segment display n 64a of display 64 shows the style numbering, and n segment display n 64b shows that expression is [C] of customization style, and n segment display n 64c, 64d step display number (corresponding to number of steps and even pin number).
Configuration switch 41 1 is connected in the step S5 of Fig. 9, just remembers in memory 26 (step S6) with the corresponding data of its demonstration.When change style or the amplitude of oscillation, by thread count [+] [-] switch 63 change styles (step S7, S8) down, when style is numbered [1]～[3], with switch 46, the 47 change amplitudes of oscillation (step S9～S11).So, the style that has changed and the amplitude of oscillation are stored in (step S5, step S6) in the memory by configuration switch 41 is connected.
Above-mentioned is the setting of beginning eyelet style, when setting termination eyelet style, step S3 judges that whether stop eyelet switch 43 connects, and only stopping eyelet LED43a lamp bright in step S4 is different settings, and other sets all identical with the setting of beginning eyelet style.
In Figure 10, express the eyelet of setting eyelet number of times (intensive seam number of times) and set handling process.(step is to S21) pin pendulum-type sample display 64 flickers (step is to S22) when configuration switch 41 is connected, when eyelet switch 42,43 is connected (step is to S23), the bright lamp of pin pendulum-type sample display, eyelet show LED42a, 43a flicker (step is to S24)., in display 64, show when the eyelet style is numbered 0-4 to S25 in step, owing to can set the eyelet number of times, thus handle eyelet style setup parameter (step is to S26).
To S27, when configuration switch 41 is switched on, preserve each data presented in step, to S28, finish the flicker that eyelet shows LED42a, 43a in step.
The flow process that under aforementioned the third customization style (original style), begins the eyelet style and set its customization style shown in Figure 11.One behaviour's customization style switch 57 and beginning eyelet switch 42 (step S41), beginning eyelet LED42a lamp bright (step S42); Configuration switch is disconnected (step S43), and the counter SW 63 of rolling off the production line is when connecting (step S44), and the n segment display n 64a of display 64 is with regard to displaying format customization numbering [5]～[9], and n segment display n 64b shows [C] (step S42).This show state is shown in the customization style table hurdle of Figure 13.In addition, one connects configuration switch 41 (step S43), and the last step display number of n segment display n 64c, the 64d of display 64 (pin number) [the reference table hurdle of Figure 13] shows needle downing position data (step S45) on display 48.
In step 46,48,52, each console switch of 54, monitor whether any switch is operated.In step S54, number of steps is increased or reduce and change by the operation counter SW 63 that rolls off the production line.The number of steps of its change is shown among n segment display n 64c, the 64d of display 64 (step S55).In addition, the pin data that fall in its number of steps can be set by operating and setting switch 46 in step S52, and it can be shown in (step S55) in the display 48.Corresponding with the Push And Release of trimming disable switch 45, the number of steps in setting as final step, in the n segment display n 48b of display 48, show [E] (step S49), by configuration switch 41 is connected, the data accumulating of needle downing position is in memory 26 in each number of steps that sets so far.
Like this,, just can form the needle downing position data of every pin by setting the data of the needle downing position in number of steps and its number of steps, i.e. pin pendulum-type sample, this style can be used as the customization style and remembers in memory 26.
In addition, the step S61 of Figure 12 illustrates the flow process that is used to set the customization style that stops eyelet to S75, substantially the same with the step S41 of Figure 11 respectively to S55, in step S61, only stop the place of eyelet switch 43 in operation, the place bright with stop eyelet LED43a lamp in switch 62 is different with step S41, the step S42 of Figure 11.
If conclude the data input of above eyelet style, when the eyelet style is [0], be and the identical style of pin pendulum-type sample, pin amplitude of oscillation degree is also identical, and eyelet number of times (intensive seam number) carries out along the flow process of Figure 10.When the eyelet style is [1]～[3], be respectively 2 point～4 a zigzag style, setting begins eyelet and still stops eyelet, and pin amplitude of oscillation degree and eyelet number of times are set according to the flow process of Fig. 9 and Figure 10.When the eyelet style is [4],, only set the pin number owing to become the straight line needle tracking.When the eyelet style was [5]～[9], owing to be the customization style, the position data of whole pin part was along the flow process input of Figure 11 and Figure 12.An example of the needle tracking when the eyelet style is identical with pin pendulum-type sample is shown in Fig. 7 (B), and eyelet style and pin pendulum-type sample are not simultaneously shown in Fig. 7 (c) or not as shown in Figure 8.
In the present invention, the setting of eyelet is to carry out according to the eyelet parameter (eyelet number of times, eyelet needle tracking number) of selection of eyelet style and setting basically.Carry out parameter setting eyelet number of times according to Figure 14.
In Figure 14, as previously mentioned, when configuration switch 41 and beginning eyelet switch 42 are connected, in pin pendulum display, demonstrate the number of times (step is to S110) of the beginning eyelet of setting.
Below, in step S111, when operation A (+) (-) switch 46 or B (+) (-) switch 47, the setting value (step to 112) that is transformed into switch 46 or switch 47 is set in beginning or the number of times that finishes eyelet, and the needle tracking when being counted N and be multiply by eyelet number of times Pn and calculate eyelet by the pin that falls in 1 pin amplitude of oscillation of eyelet hour hands pendulum-type sample is counted S (step S113).For example, the pin pendulum-type sample when eyelet begins is under 4 zigzag situations, and because of needle tracking number in 1 pin amplitude of oscillation of this style is 3, when the eyelet number of times was 3, eyelet needle tracking number was 9.Equally, the pin pendulum-type sample in the time of can setting the end eyelet.
Therefore, because the needle tracking number the when product of the eyelet number of times during from eyelet and the needle tracking number of the 1 pin amplitude of oscillation the pin pendulum-type sample is determined eyelet, set the situation of needle tracking number with eyelet alone and compare under the last eventually common state of making beginning of the pin of necessity pendulum, what can prevent to make departs from.
From the above mentioned, in step S26 in the setting of eyelet parameter, be that what to obtain eyelet needle tracking number as parameter with the eyelet number of times is example, also can replace it, the total needle tracking number during directly eyelet is set as parameter.But in this case, when this needle tracking number was not the integral multiple of needle tracking number or needle tracking number in the 1 pin amplitude of oscillation, eyelet stopped in pin pendulum way, departed from producing to make when common pin pendulum-type sample is divided a word with a hyphen at the end of a line, and sewing quality is poor.Therefore, must proofread and correct this.
In Figure 15, the eyelet parameter setting process of the total needle tracking number to eyelet time the during as parameter handled, and is that example describes with the beginning eyelet.On display 48a, show the default corrected value (step S120) of beginning eyelet needle tracking number.In Figure 15, because the needle tracking number when having set eyelet, the needle tracking that can set when beginning eyelet with A (+) (-) switch 46 in step S121 is counted Sn.Then, in step S122, count N divided by this total needle tracking number, obtain its quotient L and remainder X with the needle tracking of 1 the pin pendulum-type sample that begins eyelet.In step S123, be under 0 situation about judging at remainder X, the setting needle tracking of trying to achieve among the step S122 is counted the Sn needle tracking number (step 124) of eyelet to start with; On the other hand, be not under 0 the situation at remainder, after it is rounded up, carry out (L+1) and needle tracking again and count the N calculating of multiplying each other, this result is as the needle tracking number (step S125) of eyelet.For example, under the pin pendulum-type sample of beginning eyelet being decided to be 4 zigzag and the needle tracking number being decided to be 8 situation, because of 8/3=2.6, the eyelet number of times after rounding up is 3, so the needle tracking number is 9.
Setting when above-mentioned setting equally also can be used for the eyelet end.
Like this, owing to can proofread and correct the needle tracking number of setting by the integral multiple of needle tracking number in 1 pin amplitude of oscillation of pin pendulum, so the common pin pendulum-type sample of can not dividing a word with a hyphen at the end of a line from the eyelet way can improve sewing quality.
In addition, in the present invention, not eyelet number of times or the needle tracking number when manually setting eyelet, but set automatically together with the setting of eyelet suture needle pendulum-type sample.For this reason, made chart shown in Figure 16.For example, when carrying out common pin pendulum-type sample with 2 zigzag, repeatedly set style (2 zigzag, 3 zigzag, 4 zigzag) with the corresponding eyelet of this pin pendulum-type sample, corresponding each of memory and each eyelet pin pendulum-type sample begins eyelet and the eyelet eyelet number of times when finishing, and is stored in the memory 26 as table.
(in Figure 16, because beginning eyelet and to finish eyelet be identical, select beginning or finish that any one is all right) behind the pin pendulum-type sample when selecting eyelet,, read beginning eyelet number of times automatically and finish the eyelet number of times according to the table of Figure 16 A according to Fig. 9.Figure 16 (B), (C), (D) are representing that respectively relative eyelet pin pendulum-type sample selects the state of making under each 2 zigzag, 3 zigzag, 4 the zigzag situations.Figure 16 (B) is 2 the zigzag situations of selecting behind the eyelet, because the number of times that begins eyelet and finish eyelet according to the table of Figure 16 (A) is 4, so each begins and 2 zigzag pins pendulum repetition 4 times when finishing eyelet.In addition, Figure 16 (C), (D) are that expression is to select 3 points, 4 Zig-zags situation as pin pendulum-type sample; Because the number of times of eyelet is respectively 3 times when beginning and finishing according to the table of Figure 16 (A), so begin and 3 zigzag when finishing eyelet, 4 zigzag pin pendulum-type samples repetitions 3 times.
The example of Figure 16 (A) is to be 2 zigzag situations at common pin pendulum-type sample, also can set such table at other common a plurality of pin pendulum-type samples respectively, makes the table shown in Figure 16 (A) at each pin pendulum-type sample respectively.In addition, even without the eyelet number of times, also can count this class parameter list by memory lock suture needle mark.
Like this, owing to can under the sewing condition of each style, set the suitableeest eyelet number of times or eyelet needle tracking number at a plurality of eyelet styles respectively,, can realize high-quality eyelet so energy conversion eyelet style can automatically be set the suitableeest eyelet parameter.
Figure 17 illustrates the flow chart of eyelet action.In step S81, step on forward because of being judged as pedal, begin eyelet when connecting beginning eyelet switch 42 (step S82), so, set beginning eyelet style numbering with switch 63.Style is numbered the judgement of [0]～[9] and carries out in step S83 and S84, corresponding with style numbering separately, read beginning eyelet style from memory 26, make pin 3 synchronous according to the style of being read with the work feed effect of cloth-feeding device, the edge moves back and forth with the direction that cloth feeding direction intersects simultaneously, thereby forms and the corresponding needle tracking of each style.At this moment, when the eyelet style is [0], pin is counted the pin number identical (step S85) of N and pin pendulum-type sample, and the eyelet style is that [1]～[4] hour hands are counted the pin number (step S86) that N is the eyelet style, and the eyelet style is that [5]～[9] hour hands are counted N sets style for customization pin number (step S87).Carry out speed restriction (step S88) with the N stitch, during the pin pendulum-type sample that briefly showed by step S100 of dividing a word with a hyphen at the end of a line is made.
After this pin pendulum-type sample is made and is over, be judged as and make pedal, connect when stopping eyelet switch 43 (step S92), during the step of dividing a word with a hyphen at the end of a line S93 makes to the termination eyelet style shown in the S98 to post legged (step S91).Equally, carry out the differentiation that style is numbered [0]～[9] at step S93 and S94, corresponding with style numbering separately, read termination eyelet style from memory 26, thereby stop eyelet.At this moment, when the eyelet style was [0], pin was counted the pin number identical (step S95) of M and pin pendulum-type sample, when the eyelet style is [1]～[4], pin is counted the pin number (step S96) that M is the eyelet style, and the eyelet style is that [5]～[9] hour hands are counted M sets style for customization pin number (step S97).Carry out speed restriction (step S98) with the M stitch, in the time can carrying out trimming (step S99), in step S101, carry out trimming, thereby make release.
In addition, the eyelet style is that the needle tracking number and even the eyelet number of times (step S86, S96) of eyelet style under the 1-4 situation is the number of setting according to Figure 14, Figure 15 or proofread and correct, and also can be the number according to Figure 16 automatic setting.
In the above-described embodiment, reach the eyelet style that finishes eyelet to start with and set the needle tracking number, also can set the pin number.
As previously discussed, in the present invention, the needle tracking number when the pin pendulum number of times of having set eyelet hour hands pendulum-type sample is determined eyelet according to the product of the needle tracking number of the 1 pin amplitude of oscillation in this number of times and the pin pendulum-type sample.So, under the situation of having set single needle tracking number, the common starting position of making may be departed from after eyelet finished in the pin pendulum way, but calculate like this in the present invention under the situation of needle tracking number, owing to be after the most last eyelet of eyelet pin pendulum of necessity finishes, to make the common beginning of making, the Shi Buhui that divides a word with a hyphen at the end of a line between the pin pendulum-type sample when common pin pendulum-type sample and eyelet produces to make and departs from, and can improve sewing quality.
In addition, in the present invention, needle tracking number when having set eyelet, when carrying out eyelet according to this needle tracking number, under the situation that the eyelet needle tracking finishes,, it puts the terminal needle tracking number of pin pendulum because of automatically being corrected in pin pendulum way, so, the Shi Buhui that divides a word with a hyphen at the end of a line between the pin pendulum-type sample when common pin pendulum-type sample and eyelet produces and departs from, and can improve sewing quality.
In addition, in the present invention,,, realize high-quality eyelet even when conversion eyelet style, also can automatically set the suitableeest eyelet parameter owing to can set eyelet number of times the suitableeest in each sewing condition or eyelet needle tracking number at a plurality of eyelet styles respectively.
