[pin swing style]
In electronic sawtooth Sewing machines of the present invention, as pin swing style, the straight line needle tracking is arranged, 2 zigzag, 3 zigzag, 4 zigzag, scallop, stowing, customization style.Shown in Fig. 5 (A), the straight line needle tracking is not carry out pin swing but carry out the style of straight line needle tracking at baseline position, so pin amplitude of fluctuation (NW) is zero.Shown in Fig. 5 (D), 2 zigzag are to be benchmark with the baseline, and a pin amplitude of fluctuation falls pin in left and right stitch at 2 by pin amplitude of fluctuation (NW).Shown in Fig. 5 (E), 3 zigzag are to be benchmark with the baseline, a pin amplitude of fluctuation by 1/2nd of pin amplitude of fluctuation (NW) fall pin in a left side, center, right 3 stitch.Shown in Fig. 5 (F), 4 zigzag are to be benchmark with the baseline, a pin amplitude of fluctuation by 1/3rd of pin amplitude of fluctuation (NW) fall pin in a left side, center 2 points, right totally 4 stitch.
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.And, in the direction of circular arc left and right sides scallop is arranged.About be defined as, the inboard of Sewing machines is right, the top upside of circular arc is positioned at the inboard, at this moment, is called right scallop, then is left scallop on the contrary.Shown in Fig. 5 (C), stowing is a kind of like this stitch, that is, needle tracking begins to carry out the straight line needle tracking, is undertaken by pin amplitude of fluctuation (NW) at last 2 pins of the pin number of handling the needle, and last 1 pin returns original position, and perseveration carries out making of style.At this moment, from the pin swaying direction left and right stowing is arranged.Right (left side) stowing is pin is put right side (left side) from the straight line needle tracking a style.Have, the customization style is style (style) original copy that can make arbitrarily again.
[inherent data]
In each above-mentioned pin swing style, has pin amplitude of fluctuation (NW), baseline position (NP), baseline reference position (NPs), needle tracking starting position (NS), needle tracking final position (NE), these inherent datas of pin logarithmic data (NC).
Pin amplitude of fluctuation (NW) is represented the pin amplitude of fluctuation in each pin swing style.For example, shown in Fig. 6 (A), the 1 pin width of cloth (NWs) is that pin amplitude of fluctuation (NW) is 3 partition values during 4 zigzag.That is, NW
s=NW/3.At this moment, when drawing remainder in the partition value, be impartial about benchmark with pin amplitude of fluctuation center.Amplitude of fluctuation NW is 5.0 o'clock, NW
sSurplus in the of=1.6 0.2.Therefore, junior one pin is that 1.7, the 2 pins are that 1.6, the 3 pins are 1.7, is 1.7,1.6,1.7 when returning.In addition, for example, the pin amplitude of fluctuation during scallop is the style amplitude.In the pin swing, use the pin wobble data, the pin wobble data is by branches such as center regulation.According to style, have 24 pins, 12 pin data, calculate the calculating of the position NDp that handles the needle, be the data of handling the needle with NDn, (NW * NDn/8.2) formula carries out according to NDp=NP+.
Baseline position (NP) is meant the center of pin swing permissible range of Sewing needles swing mechanism for [0], from its center, and Sewing machines inboard (right side) be that [+], its opposition side (left side) are swung the basic point position for the pin of the pin swing of [-].Scope with scope-5.0～0～+ 5.0 that are no more than large needle amplitude of oscillation degree (WPx) is set with 0.1mm unit.For example, in setting Fig. 6 of central reference (B) for, during NP=0, the pin swing as baseline position, is carried out equably in [0] position at the center of the pin of Sewing needles swing mechanism swing permissible range about style; During NP=-2.0, being moved to the left the position of 2.0mm as baseline position from [0] position; During NP=+2.0, as baseline position, be respectively to carry out the pin swing about the center equably with the baseline position of the 2.0mm that moves right from [0] position.
Baseline position in each baseline reference when [central reference], [right benchmark] or [left benchmark] are set in baseline reference position (NPs) expression for, initial setting is set central reference for.
Shown in Fig. 6 (C), baseline position be 0.0 and the pin amplitude of fluctuation when [3], the words that baseline reference becomes left benchmark form by pin amplitude of fluctuation [3] in the left side of baseline position, form by pin amplitude of fluctuation [+3] on the right side of baseline position and baseline reference becomes the words on right side.
Shown in Fig. 7 (A), needle tracking starting position (NS) sets ensuing needle tracking starting position behind the trimming on [a right left side], and initial setting is that left needle tracking begins.And in scallop, stowing, about having, still, when right scallop, right stowing, left needle tracking begins just to have become the needle tracking starting position.
Pin number (NC) is the pin number of scallop, stowing, and when scallop, standard is 24 pins, and selenodont also is 24 pins, and equalization is 12 pins and 24 pins.Between 3～250 pins, set stowing.Initial setting is, when scallop, standard selenodont equalization is 24 pins, and stowing is 4 pins.
In addition, pin swing style begin or when stopping formed eyelet style (being also referred to as intensive style) to the straight line needle tracking, 2 zigzag, 3 zigzag, 4 zigzag, each style of scallop is effective.Intensive number of times begins to carry out with style unit to being returned as 1 style from needle tracking, and can be set in the pin number is in 19 pins.The intensive amount of sending into when in addition, intensive is set dial 7 by the intensive 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), following method is arranged: first kind of so-called pin swing style is the method for carrying out eyelet with other style; Second kind is to set as the customization of eyelet, narrows down with the interior pin amplitude of fluctuation that makes in pin amplitude of fluctuation (NW), sets the pin number, the method that the middle pin of handling the needle in pin amplitude of fluctuation (NW) is swung in the same direction; The third is an eyelet customization style (style original copy).
First kind of so-called pin swing style is to be with the method that other style is carried out eyelet, so-called pin swing style is meant, respectively when beginning eyelet, termination eyelet, just set eyelet style (PC), pin amplitude of fluctuation (CW), intensive number of times (CC), and baseline position (NP), baseline reference position (NPs), needle tracking starting position (NS) are identical with pin swing style.For example, shown in Fig. 7 (C), if be that 4 points, pin swing style 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 the pin amplitude of fluctuation is CW1, and intensive number of times is 3 times.Pin swing style continuous in this eyelet is 2 zigzag.At this moment, beginning is after eyelet is over, and needn't resemble pin swing style when determining the starting position as 2～4 zigzag, but swings open initial point and carry out the pin swing from approaching the be over pin of position of eyelet.In addition, when the beginning of the be over position and the pin swing style of beginning eyelet style is inconsistent, after eyelet is over, between a pin, give the speed restriction.And stopping the eyelet style is 3 zigzag, and the pin amplitude of fluctuation is CW2, and intensive number of times is 4 times.Stop in the eyelet at this, move on on the termination eyelet style from pin swing style, required intensive number of times+1 of a pin is intensive pin number just.
The following another kind of method of explanation, that is, customization is set as second kind of eyelet, narrows down with the interior pin amplitude of fluctuation that makes in pin amplitude of fluctuation (NW), sets the pin number, in the handling the needle in pin amplitude of fluctuation (NW) pin is swung in the same direction.Set according to this customization, every beginning eyelet stops eyelet, just can set beginning intensive needle gage pin number (CNs), stops intensive needle gage (CPe), stops intensive needle gage pin number (CNe).During intensive needle gage * intensive needle gage pin number＞pin amplitude of fluctuation, for not setting.
When the eyelet style is 2 zigzag, deduct the divide a word with a hyphen at the end of a line pin amplitude of fluctuation (N1) of intensive needle gage action pin oscillating quantity from the pin amplitude of fluctuation as common pin swing and the swing of intensive needle gage pin.The pin amplitude of fluctuation of dividing a word with a hyphen at the end of a line (N1)=pin amplitude of fluctuation (NW)-intensive needle gage (CP
*) * intensive needle gage pin number (CN
*).When 3 zigzag, deduct intensive needle gage action pin oscillating quantity from the pin amplitude of fluctuation, still, less than a pin pin amplitude of fluctuation (NTs) time, be the pin amplitude of fluctuation (NTe) of dividing a word with a hyphen at the end of a line.When 3 zigzag, deduct intensive needle gage action pin oscillating quantity from the pin amplitude of fluctuation, but, greater than a pin pin amplitude of fluctuation (NWs) time, deduct pin amplitude of fluctuation after the pin pin amplitude of fluctuation part as dividing a word with a hyphen at the end of a line pin amplitude of fluctuation (NI), control intensive needle gage pin swing successively, the pin of dividing a word with a hyphen at the end of a line swing, pin pin swing.4 zigzag too, when deducting remainder (NN) after the intensive needle gage amplitude and spending greater than a pin pin amplitude of oscillation, the remainder of removing NN with a pin pin amplitude of oscillation degree is as dividing a word with a hyphen at the end of a line pin amplitude of oscillation degree (N1), it is discussed as a pin pin amplitude of oscillation degree pin number (NCn).Intensive pin number is to deduct [intensive needle gage pin number and divide a word with a hyphen at the end of a line pin number and residue style pin number] remaining pin number in back, and pin pendulum-type sample is the number of times of available this pin number.The style of carrying out intensive needle gage also is calculated as a style.
Fig. 8 illustrates the beginning eyelet needle tracking of 3 styles for example.
[setting of baseline reference, baseline position]
According to the present invention, for a plurality of pin swing styles, for example, 2 zigzag, 3 zigzag, 4 zigzag each pin swing styles, as shown in Figure 9, for each pin swing style, store with the form of table by the base-line data that baseline position or baseline reference constitute.This carries out like this: each pin swing style selector switch of operating 51,4 zigzag switches 52 of 50,3 zigzag switches of 2 zigzag switches, connect baseline switch 61 successively for selected pin swing this moment style, select any one baseline reference (central reference S, right benchmark R, left benchmark L), and with switch 46,47 make the baseline position that is shown in the display 48 for+-, and the baseline position of input defined.Shu Ru the data form that is used in the such table of Fig. 9 is stored in the memory 26 like this.
When making according to pin swing style, connect pin swing style selector switch 50～57, select desirable pin swing style.At this moment,, read this pin swing style, simultaneously, from table shown in Figure 9, read and relevant baseline position and the baseline reference of this pin swing style owing to be stored in the memory 26 with the corresponding pin wobble data of this pin swing style.Motor 11 is controlled in main motor 1 and pin swing that Sewing machines rotation control circuit 21 and pin swing control circuit 24 are controlled Sewing machines according to these data, swings the needle tracking of style thereby just formed with baseline reference and the corresponding pin of baseline position.
In the table of Fig. 9, formed style is shown among Figure 10.The pin amplitude of oscillation degree of each style is W, and when 2 zigzag, it is the data of middle position S for [0], baseline reference that pin wobble data (the pin data fall) is transformed into baseline position, according to this Data Control pin swing mechanism.So just formed shown in Figure 10 (a) with baseline position and the corresponding style needle tracking of baseline reference.And when 3 zigzag, be the data of right benchmark R because the pin data that fall are transformed into baseline position for [+1.0], baseline reference, so just formed the style needle tracking shown in Figure 10 (b).When 4 zigzag, be the data of left benchmark L because the pin data that fall are transformed into baseline position for [1.0], baseline reference, so just formed the style needle tracking shown in Figure 10 (c).
In addition, in the present embodiment, because the full swing amplitude is-5.0～+ 5.0, for example, when amplitude of fluctuation is set in central reference by 5mm, if baseline position sets for+and 3.0 or-3.0, because left end pin swing position or right-hand member pin swing position have surpassed the full swing amplitude of Sewing machines, so refuse such setting.
Also have, though in table, store baseline position and baseline reference relatively with each pin swing style,, also can be any of baseline position and baseline reference.
Like this, for each pin swing style, store the baseline reference and/or the baseline position of optimal baseline respectively, because for selected pin swing style, can automatically set these base-line datas, thereby, the setting of base-line data can not slipped up, and just can form high-quality pin swing style needle tracking.
Have again, when the such base-line data of change baseline position or baseline reference, when pin being moved, become easy because baseline is involutory with it, therefore synchronously control the pin rotary actuator with the input of baseline position or baseline reference, pin is moved to baseline reference or the baseline position of being imported.
In Figure 11, configuration switch 41 and baseline switch 61 1 are connected (step S1, S2), and baseline position just is shown in (step S4) in the display 48.During with A+-switch 46 or B+-switch 47 change data (step S5), judge that with step S6 the pin of Sewing machines is whether in last position stops.This can detect by synchronized 23.Stop in last position with step S7 control pin rotary actuator 11, shank 2 or pin 3 being moved with doing the baseline change when middle.Plan when mobile, with step S8 configuration switch 41 is connected, with end process.Do not plan to turn back to step S5 when mobile, repeat above-mentioned processing.
In addition, be judged as when not stopping with step S6 in last position, with step S9 the change data are stored in the memory 26, after configuration switch 41 is connected (step S10) and detected the position (step S11), make shank do the baseline change and move and move it to the baseline position place (step S12) that is imported.
Like this, when carrying out location change in last position stops, shank also synchronously moves (step S7) with its change, and in the time of in addition, when detecting on next time the position (step S11), shank moves (step S12).And, when step S2, step S5 negative evaluation,, do not press and do not return the original place when connecting again by the end process when disconnecting of configuration switch 41 next time, begin to handle (step S3).
Though above-mentioned is the baseline position change,, during the change baseline reference, the baseline reference of importing or changing according to institute makes the change of shank do move equally.
The change of this baseline position or baseline reference since often be with make relevant adjust of thing and carry out when making the conjunction (binder) 70 (Fig. 2) that thing leads, shank is also synchronously mobile with the baseline change, so baseline is involutory just becomes easy.For example, baseline position is positioned at the position of conjunction 70, when baseline reference is chosen as left benchmark, each pin swing style is that basic point is all swung towards the right side with the position of conjunction 70, thereby, even when the pin amplitude of fluctuation changes, also baseline position needn't be adjusted again, thereby operating efficiency can be improved.
In addition, though baseline reference has central reference, right benchmark, left benchmark,, when setting central reference as baseline reference, the pin swing position is just difficult involutory with conjunction.Therefore, can from central reference, right benchmark, left benchmark, select baseline reference.Like this, because every connection baseline switch 61, baseline reference has central reference, right benchmark, left benchmark, and therefore each connection can both be selected wherein any one.
When electing central reference as with the step S20 baseline reference of Figure 12, step S21 forms the pin data that fall to the pin amplitude of fluctuation with branches such as base centers.For example, during 2 zigzag, the pin amplitude of fluctuation is W and baseline position when being NP, and right needle downing position is NP+W/2 just, and left needle downing position is NP-W/2.
On the one hand, when baseline reference was judged as right benchmark with step S22, the maximum right pin swing position of style was benchmark (baseline), made pin data (step S23) for its left side.When being judged as left benchmark, the maximum left pin swing position of style is benchmark (baseline), makes pin data (step S24) for its right side.For example, the example of step S23 is shown, is the customization style in pin swing style, the pin data that fall be D1, D2, D3 ... during Dn, if its base-line data is Dr, the pin data that fall just are (NP-Dr)+Dn.
Like this,, make the action of main motor and pin rotary actuator, the needle tracking of corresponding formation pin swing style with selected baseline reference owing to make the pin data according to baseline reference.
In addition, in the above-described embodiments, though with the synchronously mobile pin of the input of baseline position or baseline reference, also can move asynchronously.
As discussed above, according to the present invention, store at least a in the baseline reference of optimal baseline and the baseline position respectively for each pin swing style, owing to can automatically set these base-line datas for selected pin swing style, thereby the setting of base-line data can not slip up, and just can form high-quality pin and swing the style needle tracking.
In addition, according to the present invention, the change of baseline position or baseline reference often is to utilize with the relation of making thing to be undertaken by the conjunction of adjusting making the thing guiding 70 (Fig. 2), at this moment, shank also moves along with baseline change, so baseline is involutory just becomes easy.
According to the present invention, owing to can be chosen as right benchmark or left benchmark to baseline reference, the relative baseline of pin is all towards the right side or the left side swing in each pin swing style, thereby, even when the pin amplitude of fluctuation changes, also needn't adjust baseline position again, thereby can improve operating efficiency.
