[pin pendulum-type sample]
In electronic sawtooth Sewing machines of the present invention, as pin pendulum-type sample, the straight line needle tracking is arranged, 2 zigzag, 3 zigzag, 4 zigzag, scallop, stowing needle tracking, customization style.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 benchmark 1 pin amplitude of oscillation degree falls within left and right stitch at 2 by pin amplitude of oscillation degree (NW) pin with the baseline.Shown in Fig. 5 (E), 3 zigzag are, and to be benchmark 1 pin amplitude of oscillation degree with the baseline fall within a left side, center, right 3 stitch by 1/2nd pins of pin amplitude of oscillation degree (NW).Shown in Fig. 5 (F), 4 zigzag are, and to be benchmark 1 pin amplitude of oscillation degree with the baseline fall within a left side, center 2 points, right totally 4 stitch by 1/3rd pins of pin amplitude of oscillation degree (NW).
Shown in Fig. 5 (B), scallop is the selenodont style needle tracking of making by 12 pins or 24 pins in two circular arcs, and [standard selenodont 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 scallop.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 scallop, otherwise, then be called left scallop.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 pin amplitude of oscillation degree (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 pin amplitude of oscillation degree (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).
Pin amplitude of oscillation degree (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 divided into 3 fens evil values of cutting to pin amplitude of oscillation degree (NW) during 4 o'clock 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 scallop 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 set the center reference five equilibrium for, 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, pin amplitude of oscillation degree (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 [a right left side] side and specifies the withdrawal of needle position after being connected on trimming, and initial setting is left withdrawal of needle.Have again, in scallop, stowing needle tracking, though about having, still, when right scallop, 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 scallop, stowing needle tracking, and when scallop was made, standard was 24 pins, and selenodont 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 scallop was made, standard selenodont 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 scallop.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 amount of sending in intensive when seam is set dial 7 by the intensive seam amount of sending into and is set.For example, when 4 zigzag, shown in Fig. 7 (B), can be 6 styles, in the style 3 pins are arranged, thereby the pin number is 18.
In addition, set as the selection of eyelet (intensive seam), following method is arranged: first kind is meant that all styles of that adopts so-called pin pendulum-type sample carries out the method for eyelet; Second kind is meant as the customization of eyelet and sets, pin amplitude of oscillation degree (NW) with the interior pin amplitude of oscillation degree that narrows down, set the pin number, the method that the middle pin of handling the needle pin amplitude of oscillation degree (NW) in is swung in the same direction; The third is meant and 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, set the beginning eyelet, stop eyelet, eyelet style (PC), pin amplitude of oscillation degree (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, stopping the eyelet style, to be at 3 be that example describes with beginning eyelet style, then beginning the eyelet style is 4 zigzag, and pin amplitude of oscillation degree is that CW1, intensive seam number of times are 3 times.Continuous pin pendulum-type sample is 2 zigzag in this eyelet, and in this case, beginning eyelet end back,, is arranged initial point from the pin that more approaches the eyelet end position and carried out the pin pendulum in the time of needn't determining the starting position as 2～4 zigzag according to pin pendulum-type sample.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.And 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 from pin pendulum-type sample, required intensive seam number of times+1 pin of a pin is intensive suture needle number just.
Second method below is described, customization is set as second kind of eyelet, and the pin amplitude of oscillation that narrows down in pin amplitude of oscillation degree (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 amplitude of intensive seam (CPs), beginning intensive seam close needle gage pin number (CNs), stop the close needle gage amplitude 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, pin amplitude of oscillation degree 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 (N1)=pin amplitude of oscillation degree (NW)-Mi needle gage (CP
*) * close needle gage pin number (CN
*).When the eyelet style was 3 zigzag, if pin amplitude of oscillation degree deducted close needle gage action pin pendulum amount less than 1 pin pin amplitude of oscillation degree (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 pin amplitude of oscillation degree deducts close needle gage action pin pendulum amount greater than 1 pin pin amplitude of oscillation degree (NWs), just the pin amplitude of oscillation degree after the deduction 1 pin pin amplitude of oscillation degree 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 too, when deducting remainder (NN) after the close needle gage amplitude and spending, 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 1 pin pin amplitude of oscillation degree with 1 pin pin amplitude of oscillation degree 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 is stored in (step S6) in the memory 26 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.
Be used to set the handling process of the eyelet number of times (intensive seam number of times) that stops the eyelet style shown in Figure 10.When configuration switch 41 is connected (step S21), 64 flickers (step S22) of pin pendulum-type sample display.When eyelet switch 42,43 is connected (step S23), pin pendulum-type sample display lamp is bright, eyelet display led 42a, 43a glimmer (step S24).In step S25, the eyelet style that display 64 shows be numbered [0]～[4] time, can set the eyelet number of times, thereby when beginning eyelet in step S27, display 48a shows beginning eyelet number of times, and when stopping eyelet, display 48a show to stop the eyelet number of times, the eyelet style be numbered [0]～[4] in addition the time, display 48a, 48b show [P] (step S26) respectively.
When configuration switch 41 is connected among step S28, the S29, preserve each data presented.Eyelet LED42a, 43a flicker stops among the step S30, and display 48 shows the pin amplitude of oscillation (step S30).In addition, during change eyelet number of times, configuration switch 41 is disconnected in step S29, uses the corresponding switch 46 change beginning eyelet number of times with display 48a, uses with corresponding switch 47 changes of display 48b and stops eyelet number of times (step S31, S32).
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 operation 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 of needle downing position are stored in the 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 and customizes style and be stored in the 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.
[whole action]
Figure 14 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, move back and forth along the direction vertical simultaneously, thereby form and the corresponding needle tracking of each style with cloth feeding direction.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.
