In addition, the ROM9a of ROM dial plate 9 is connected on the bus 52 by connecting portion 13.
In ROM48, as shown in Figure 7, except system control program, additional have comprise the various driving mechanisms of drive controlling and select practical style simultaneously or embroidery pattern carries out the control program of making that style is selected control or various demonstration control, storing the distinctive work feed playback control program of the application etc. in advance.In this work feed playback control program, include activation point data creating control path (being equivalent to data creating mechanism), phase angle, data storage control path, manual operation with controlling path (being equivalent to the manual operation controlling organization) etc.At this, by CPU47 or make control program etc. and constitute controlling organization.
In the ROM9a of ROM dial plate 9, the same with ROM48, storing the lower multiple embroidery pattern stitch data of usage frequency.
Below, according to the flow chart of Fig. 9 the path is controlled in the phase angle activation point data creating storage of being implemented by control device 45 and described.At this, in ROM48, can store the allocation process program, this allocation process program is counted control to count value, according at every turn from X to turned position detection signal from the relevant turned position X of motor 23 to detecting sensor 36,37 receptions that carry, perhaps at every turn from Y to carrying the relevant turned position Y of motor 24 to the turned position detection signal that detecting sensor 53,54 receives, make X increase respectively or reduce to the count value YP of conveying counter 49d to count value XP that carries counter 49c and Y.
At this, begin earlier from making, as shown in Figure 8, make parameter setting sewing speed, conveying a plurality of pre-set parameters such as pick up counting by what show on the color monitor 10.But, in the display part of color monitor 10 downsides, usually show [the phase angle activation point data creating key] of making phase angle activation point data, begin to operate [manual operation key] that conveying action that handwheel 8 makes embroidery tambour 21 reproduces, make various controls implement [mute key] that finishes.
Make the parameter setting screen displayed at this and piece formula cursor key BK, punctuation key and arrow key.These membrane keyboards 11 of operation that the operator is suitable just can be set respectively, and for example [sewing speed] being set at [1300] changes, and [conveying picks up counting] is set at [+10].This conveying pick up counting [+10] be common timing, can be set in [0～20] scope.
In addition, by inserting power supply to sawtooth seam sewing machine M, just can carry out X to carrying motor 23 and Y to handle to the initial setting of carrying motor 24, X is to carrying motor 23 and Y to lay respectively at reference position K to conveying motor 24, and embroidery tambour 21 is set in its origin position.And shank 5 is positioned at its uppermost position in fig-ure.
Behind the needle tracking style that the operator selects Gong to make, by activation point data creating key assignments phase angle, phase of operation angle activation point data creating pattern, in case operation start shutdown switch 12 just can begin control by control device 45.
At first, according to the phase detection signal that receives from rotation phase detecting sensor 15a, 15b, read the value (step S11) of the rotation phase angle θ of machine spindle 7.And, when rotation phase angle θ increases by 2 ° of numerical value (step S12: be), to carrying counter 49c to read X, simultaneously, read Y to carrying count value YP (step S13) to conveying counter 49d from Y to carrying count value XP from X.
Secondly, with respect to the rotation phase angle θ of machine spindle 7, making and these X are to carrying count value XP and Y to carrying count value YP respective phase angle activation point data (step S14).
The phase angle activation point data of making like this are stored among the activation point data storage 49e of phase angle (step S15), if stitch data does not finish (step S16: deny), execution in step S11～step S16 repeatedly.Under the situation that finishes to make according to stitch data (step S16: be), finish this control.
At this, step S11～step S14 is equivalent to data creating mechanism.
At this, in Figure 11 and Figure 12, the needle tracking style represents that as being made of under the situation of eyelet needle tracking a plurality of pin numbers the X relative with machine spindle 7 rotation phase angles is to carrying count value XP and Y to the relation of carrying count value YP.When the rotation phase angle θ of machine spindle 7 was about 310 °, X was [0] to carrying count value XP, and the X that slowly rises is to carrying count value XP to be [90] to the maximum thus.Being equivalent to during this increase with the even number needle tracking is the conveying timing of target, and X is during carrying that motor 23 number of drive pulses in accordance with regulations drives in the turn direction.And above-mentioned X carries that to be equivalent to the odd number needle tracking during count value XP reduces be the conveying timing of target, and X is during carrying that motor 23 number of drive pulses in accordance with regulations drives in reverse direction.
In addition, Y was [0] to count value YP when the rotation phase angle θ of machine spindle 7 was about 290 °, and the maximum of Shang Shenging is [160] thus.It is the conveying timing of target that this Y is equivalent to the even number needle tracking during carrying count value to increase, and Y drives in the turn direction to conveying motor 24 number of drive pulses in accordance with regulations in this period.And it is the conveying timing of target that Y was equivalent to the odd number needle tracking to the period of carrying count value YP to be reduced to [0] from [160], this period Y to carrying motor 24 number of drive pulses in accordance with regulations to drive in the de-rotation direction.
So X is [90] to the maximum of carrying count value XP, its minimum of a value is [0]; Y is [160] to the maximum of carrying count value YP, and its minimum of a value is [0].
The X relative with the rotation phase angle θ of machine spindle 7 is to carrying motor 23 and Y to represent as shown in figure 11 to change to each count value XP, YP of carrying motor 24.
Therefore, in the activation point data storage 49e of phase angle, as shown in figure 12, the rotation phase angle θ of machine spindle 7 is respectively 0 °, 2 °, 4 °, 6 ° ... the time, the X of corresponding successively storage is to carrying count value XP and Y to carrying count value YP.Promptly, store phase angle activation point data in the activation point data storage 49e of this phase angle, these phase angle activation point data are corresponding to the rotating drive position of carrying motor 24 to rotating drive position of carrying motor 23 and Y with the per 2 ° of rotation phase angle θ and the X of machine spindle 7.
Below, the manual operation of control device 45 being implemented according to the flow chart of Figure 10 describes with the control path.In case operate manual operated key and set manual operation mode by the operator, just begin this control.
At first, in case,, read the rotation phase angle θ (step S21) of machine spindle 7 for example in the manual operation of turn direction by operator's manual operation handwheel 8.(step S22: be) under corresponding to the situation of value storage in the activation point data storage 49e of phase angle of this rotation phase angle θ, read with the corresponding X of this rotation phase angle θ to carrying count value XP and Y to carrying count value YP (step S23).
In addition, manually under the situation that handwheel 8 rotates, read the corresponding X of rotation phase angle θ with machine spindle 7 in the de-rotation direction to carrying count value XP and Y to carrying count value YP.
Secondly, to carrying count value XP to drive X, drive Y to carrying motor 24 (step S25) to conveying count value YP according to the X that reads according to the Y that reads to carrying motor 23 (step S24).That is, be equivalent to X from turned position X before the several turned position detection signal of carrying count value XP to detecting sensor 36,37 receptions, X of every pulsed drive is to carrying motor 23; Be equivalent to Y from turned position Y before the several turned position detection signal of carrying count value YP to detecting sensor 53,54 receptions, Y of every pulsed drive is to carrying motor 24, corresponding therewith mobile embroidery tambour 21.
Subsequently, carry out same step S21～step S25 repeatedly, when the moving machine spindle 7 of the manual operation revolution of handwheel 8 had 2 °, embroidery tambour 21 carried out minute movement continuously.But under the situation of handwheel 8 by the manual operation backwards rotation, because of the rotation phase angle reduces, to carrying motor 23 and Y to the driving of carrying motor 24, embroidery tambour 21 is along with the reverse order of making successively according to so-called normal sequence moves by corresponding X therewith.
In order to finish manual operation mode, in manual operation was carried out with control, (step S26: be) finished this control under the situation of EO key, removes manual operation mode.Therefore, the operator carries starts continuously according to the embroidery tambour due to the manual operation of handwheel 8 21, on one side change make [sewing speed] of parameter, changes [conveying picks up counting] on one side etc. can be adjusted the fine finishining of needle tracking in better outward appearance mode.
So; according to the needle tracking data of needle tracking style when carrying out actual making; in the activation point memory 49e of phase angle, store phase angle activation point data; these phase angle activation point data are with each minor rotation phase angle θ of machine spindle 7 defineds and by representing that X is corresponding to the rotating drive position of carrying count value YP to be constituted to the Y of conveying motor 24 turned positions to conveying count value XP and expression Y to the X that carries motor 23 turned positions; owing to can carry out manual operation when manual operation mode is set with controlling; so use the phase angle activation point data of in the activation point data storage 49e of this phase angle, storing; by manual operation handwheel 8 machine spindle 7 is rotated simultaneously, can verily control X to carrying motor 23 and Y to the rotation of carrying motor 24.
Therefore, make flowing mode and at length reproduce start, can improve repeatability because the actuator state of the embroidery tambour 21 can be to actual making the time is carried with existing mechanically driver type.
Below, the change embodiment that part in the previous embodiment is changed describes.
1, phase angle activation point data creating shown in Figure 9 is stored in the control, and the each minute angle of stipulating more than 1 ° or 3 ° that only increases of the rotation phase angle θ of machine spindle 7 also can be made phase angle activation point data.
