Eedle swing mode

Electronic sewing machine of the present invention, its eedle swing mode possess that straight line is made, 2 serration types, 3 serration types, 4 serration types, flounce formula, blind stitch pin, conventional form.Straight line is made, and shown in Fig. 5 (A), eedle is not swung, and is the mode of making at baseline position; Eedle swing width (NW) is 0.2 serration types shown in Fig. 5 (D), are as the criterion in the swing width (NW) of the 1 pin mode of making at left and right 2 following pins with baseline; 3 serration types, shown in Fig. 5 (E), with baseline be as the criterion and with the swing width (NW) of 1 pin 1/2 on a left side, the mode of making of center, right 3 following pins; 4 serration types, shown in Fig. 5 (F), with baseline be as the criterion and with the swing width (NW) of 1 pin 1/3 a left side, in the mode of making of 2 points, right 4 following pins.

In addition, the flounce formula shown in Fig. 5 (B), is the crescent pattern made from 12 pins or 24 pins in 2 circular arcs, and the kind of handling the needle has " standard, crescent, equalization " 3 kinds.And, with circular arc towards the branch that left and right sides flounce formula is arranged, about regulation be when a side in the bosom of Sewing machines as the top of the right side and circular arc on a side for the bosom in during a side, be called right flounce formula, when being called left flounce formula for opposite the time.The blind stitch pin shown in Fig. 5 (C), carries out straight line when making beginning and makes, and does not carry out the eedle swing with eedle swing width (NW) at the final 2 pin places of the pin number of handling the needle, and carries out and will return the method for sewing of origin-location mode perseveration at final 1 pin place.At this moment, be divided into left and right blind stitch pin according to the eedle swaying direction, right (left side) blind stitch pin is to make to the right the mode that (left side) carries out the eedle swing from straight line.In addition, the convention mode of making is that the prototype that makes is arbitrarily made mode.

Inherent data

In each above-mentioned eedle swing mode, eedle swing width (NW), baseline position (NP), baseline reference position (NPs) are arranged, make the inherent data of starting position (NS), sewing finishing position (NE), pin number (NC).

Eedle swing width (NW) is the eedle swing width that is illustrated in each eedle swing mode, and for example, shown in Fig. 6 (A), 1 pin width (NWs) of 4 serration types is that eedle swing width (NW) is divided into 3 parts value.That is NWs=NW/3.At this moment, if remainder appears in partition value, just the center with the eedle swing width is to equate about benchmark makes.NW is 5.0 o'clock, and NWs=1.6 surpluss 0.2.So initial pin is 1.7, the 2 pins is that 1.6, the 3 pins are 1.7, is 1.7,1.6,1.7 when returning.Again for example, the eedle swing width during the flounce formula is the width of figure, and what eedle was swung usefulness is the eedle wobble data, and eedle wobble data regulation is with the center separated into two parts.According to pattern, 24 pins, 12 pin data are arranged, if represent the data of handling the needle with NDn, NDp represents the position of handling the needle, NP represents baseline position, so according to the NDp=NP+ (position calculation of handling the needle of NW * NDn/8.2).

Baseline position (NP), shown in Fig. 6 (B), with the center of sewing machine needle swing mechanism as " 0 ", be called with a side in the Sewing machines bosom and be "+" (right side), the swing basic point position of the eedle swing that its opposite side is "-" (left side), be no more than maximum eedle swing width (WPx), be set in-5.0～0～+ 5.0 the scope.

Baseline reference position (NPs), shown in Fig. 6 (C), baseline reference position when having shown and to be set at " be benchmark separately, the swing of right-hand member benchmark, the swing of left end benchmark " with the center, it is that benchmark separates that initial setting can be set at the center, with respect to baseline position (NP), at central authorities, right, left side appointment swing benchmark.For example, in 2 serration types, baseline position (NP)=0.0, eedle swing width (NW)=3.0, during baseline reference position (NPs)=left side, eedle is swung between 0.0 and 3.0.

Making starting position (NS), shown in Fig. 7 (A), is that the following starting position of making together behind the cut-out line is set at " left and right ", and its initial setting is made from a left side.In addition, though about having in flounce formula, blind stitch pin, and when right flounce formula, right blind stitch pin, a left side is made to begin to become and is made the starting position.

Pin number (NC) is the pin number of flounce formula and blind stitch pin, and when being the flounce formula, standard is 24 pins, and crescent also is 24 pins, if equalization then is 12 pins and 24 pins, the blind stitch pin then is set between 3～250 pins.For initial setting, when being the flounce formula, for standard, crescent moon, equalization be 24 pins, and the blind stitch pin is 4 pins.

In addition, make the terminal of formation and make mode (also becoming compact mode) by carry out terminal in the beginning of eedle swing or when finishing, for straight line make, each figure of 2 serration types, 3 serration types, 4 serration types and convention mode is all effective.Intensive number of times is to begin to carry out as the grapheme of 1 figure till returning from making, and the pin number can be set in 19.And the intensive cloth feed amount when intensive is set by intensive dial 7.For example, when being 4 serration types, shown in Fig. 7 (B), 6 sawtooth can be arranged, because 1 sawtooth has 3 pins, so the pin number is 18.

And, make the selection of (intensive) sets as terminal, can set and use other mode different to carry out the method that terminal is made with eedle swing mode, with eedle swing width (NW) is established the narrow pin number of setting with the eedle swing width of interior 1 pin, handling the needle in the eedle swing width (NW) carried out the method for eedle swing to same direction.

Carry out the method that terminal is made with other mode of making different with eedle swing mode, be each to be begun terminal make and finish terminal and make and be set at terminal slot drawing shape (PC), eedle swing width (CW), intensive number of times (CC) in addition, so that baseline position (NP), baseline reference position (NPs) and eedle are swung mode is the same.For example, shown in Fig. 7 (C), if with 4 serration types to start with terminal make, 2 serration types are swung mode as eedle, and 3 serration types are made as example as the end terminal slot and describe, and it is 4 serration types that the beginning terminal is made, the eedle swing width is CW1, and intensive number of times is 3 times.Beginning terminal at this, to make follow-up continuous eedle swing mode be 2 serration types, at this moment, after the beginning terminal sewing finishing, if eedle swing mode, do not determine the starting position about 2-4 point serration type, make near the end position eedle from terminal and swing open initial point and carry out the eedle swing.And when the eedle position and the starting position of eedle swing mode that the beginning terminal mode of making finishes were inconsistent, after the terminal sewing finishing, when moved described end eedle position and described beginning eedle position, the speed that give between 1 pin was controlled.And finishing the terminal mode of making is 3 serration types, and the eedle swing width is CW2, and intensive number of times is 4 times.It is to move to finishing the terminal mode of making from eedle swing mode that this end terminal is made, but owing to need 1 pin, therefore make intensive number of times+1 pin of mode as intensive pin number to finish terminal, to drive the described solenoidal state of making that returns, according to the cloth feed amount work feed of intensive dial 7 settings.

The baseline position change

Below, the embodiment that the baseline position of each eedle swing mode when terminal is made and when making usually changes formed pattern stitching describes.For the eedle swing mode of making usually, it begins and finishes the baseline position that terminal is made mode and relative baseline position, eedle swing width and other each pattern of setting, also have the following pin data of convention pattern etc.,, and deposit in the memory 26 all by the guidance panel input.

In Fig. 8, when also being not activated the switch 42 that the beginning terminal makes (step S1 not), from memory, read and make eedle swing mode, relative baseline position NP and the eedle swing width (step S2) made usually usually, current when stepping on plate (step S3), carry out common eedle wobbling action (step S11) at baseline position NP and in the eedle swing mode of its eedle swing width.

On the other hand, when pressing the switch 42 that the beginning terminal makes, judge whether to make (step S4) for convention is intensive.It is that following pin data according to each pin of input make that so-called intensive convention is made, and according to the terminal stitch data of memory in the memory (memory storage) 26, the intensive stitching of making that forms in the beginning of eedle swing mode or when finishing.Make when not being that intensive convention is made when terminal, judge whether the baseline position that terminal is made, made usually sets (step S5) respectively.If do not set respectively, just from memory, read respectively the beginning terminal make mode and make usually eedle swing mode, the beginning terminal relevant with them make baseline position NP1, begin terminal make the eedle swing width, usually make baseline position NP, make eedle swing width (step S6) usually.At this moment, NP1, NP are set to same value N1.

On the other hand, when setting respectively, equally, from memory, read respectively the beginning terminal make eedle swing mode and make usually eedle swing mode, the beginning terminal relevant with them make baseline position NP1, begin terminal make the eedle swing width, usually make baseline position NP, make eedle swing width (step S7) usually.At this moment, baseline position is set at NP1=N2 respectively, the value that NP=N1 is different.

Then; moving to step S8 makes shank move to the primary position made of beginning terminal; step on plate (step S9) before the wait, begin the terminal slot braking with above-mentioned setting value and make (step S10), then begin common eedle wobbling action (step S11) at baseline position NP.When pedal is in the neutral position (step S12 is), stop Sewing machines (step S13), and post legged pedal (step S14 is), if speed (step S15 is) that can tangent line, the processing (finishing terminal makes) that just enters Fig. 9.

In Fig. 9,, intactly carry out tangent line (step S27), and carry out end process closing when finishing terminal and making switch 43 (step S21 not).In addition, finish terminal and make switch 43, but terminal is made when not being intensive convention (step S22 not), judges whether that setting terminal is made baseline position and made baseline position (step S23) usually respectively when opening.If do not set respectively, terminal will be made eedle swing mode and relative end terminal is made baseline position NP2=N1 setting respectively with the eedle swing width if then will finish, to finish then that terminal is made eedle swing mode and relative end terminal is made baseline position NP2=N3 and the eedle swing width reads in memory (step S24, S25) respectively, and finish terminal at baseline position NP2 place and make (step S27).

In Figure 13 (A), (B), having shown when beginning the terminal mode of making is 4 serration types, usually the mode of making is 2 serration types, and when finishing the terminal mode of making and being 3 serration types, and baseline position is not set (same setting) and the example of setting respectively respectively.Figure 13 (A) is not for setting example respectively, that a kind of mode baseline position all is N1, and Figure 13 (B) is for setting example respectively, setting the beginning terminal respectively, to make the baseline position of mode be N2, and the baseline position of making mode usually is N1, and finishing terminal, to make the baseline position of mode be N3, forms the stitching of its pattern respectively.

Be judged as intensive convention when making when respectively the terminal among the step S22 of the step S4 of Fig. 8 and Fig. 9 being made, carry out the processing among Figure 10.Promptly, when in step 4, being judged as intensive convention when making, from memory, read respectively the intensive convention of beginning with following pin data DnS, make eedle swing mode usually, the relative baseline position of making usually is NP, eedle swing width (step S31), judges that it is irrelevant setting or synchronization settings (step S32) that intensive convention is made with making baseline position usually.When being judged as synchronization settings (step S32 denys), to begin that pin data DmS is modified to DmS=DnS+NP (step S33) under the intensive convention, if be judged as irrelevant set (step S32 is), just following pin data are not revised, enter the step S9 of Fig. 8, step on plate before the wait, begin terminal according to the intensive convention data of beginning and make.

In addition, make when being judged as intensive convention and making when finishing terminal among the step S22 at Fig. 9, from memory, read in and finish intensive convention pin data DnE (step S34) down, when being judged as that intensive convention is made and making when being synchronization settings (step S35 not) usually, pin data DmE under the intensive convention of end to be modified to DmE=DmE+NP (step S36), and if irrelevant setting (step S35 is), just do not revise down the pin data, finish terminal with the intensive convention data of end respectively and make (step S37), the step S27 that enters Fig. 9 carries out the end process of tangent line.

Having shown regulation in Figure 13 (C) begins and finishes intensive convention and make, for example when making usually when being 2 serration types of baseline position NP=1, from step S32 to S35, if being judged as intensive convention makes and common baseline synchronization settings, then shown in Figure 13 (D), make with the convention of carrying out of revising data pin data+1 under the intensive convention; If irrelevant the setting, then shown in Figure 13 (E), portion is not revised intensive convention data in addition, carries out convention and makes.

In addition, at the step S5 of Fig. 8 and the step S23 of Fig. 9, and the step S32 of Figure 10, the 35th, judged whether to set respectively the baseline position that terminal is made and made usually, or, the processing of these settings has been shown in Figure 11 and Figure 12 not for the irrelevant step of setting.

When setting terminal make and the baseline position made usually for setting respectively or same setting the time, as shown in figure 11, start configuration switch 41 and detailed configuration switch 59 (step S41) at first simultaneously, then start right blind stitch foot control 56 (step S42), on eedle swing display 48, demonstrate ON/OFF and demonstrate setting content.When showing ON, the expression terminal is made with the baseline position of making usually and is set respectively.And when showing OFF, represent same setting.If the change setting content is used display switch 46,47 change ON or OFF (step S44, S45), start configuration switch 41 (step S46), deposit setting content in the memory 26 (step S47).

In addition, the baseline position of making and making usually in the intensive convention of setting is when haveing nothing to do setting or synchronization settings, as shown in figure 12, start configuration switch 41 and detailed configuration switch 59 (step S51) simultaneously, then start left blind stitch foot control 55 (step S52), on eedle swing display 48, demonstrate ON/OFF, and demonstrate setting content.When showing ON, represent that the baseline position that intensive convention is made and made usually is the setting that has nothing to do, and when showing OFF, represents same setting.If the change setting content with display switch 46,47 change ON or OFF (step S54, S55), and starts configuration switch 41 (step S56), then setting content is deposited in (step S57) in the memory 26.

Like this, at the step S5 of Fig. 8 and the step S23 of Fig. 9, and among the step S32 of Figure 10,35, just whether the baseline position that can make and make usually terminal respectively sets (same setting) respectively, or do not have nothing to do setting (synchronization settings), simply judge according to the content of reading from memory.
