In addition, Sewing machines 10 has: the first control substrate 40, and the power supply of its subtend sewing machine electromotor 24 and each several part is supplied with and is controlled; And second control substrate 60, it carries out the control of peripheral device.
Be equipped with at the first control substrate 40: main power circuit 41, it accepts the example from the source power supply 200(external power source of outside) power supply supply with, to each structure supply capability of Sewing machines 10; Motor driver 42, it is supplied with by the electric power from main power circuit 41, drives sewing machine electromotor 24; The example of master control part 50(power control part), it is controlled main power circuit 41 and motor driver 42 at least; I/O interface 43, it is used for main power circuit 50 is connected with each structure of Sewing machines; And the example of power supply generative circuit 44(auxiliary power circuit), it is from main power circuit 41 to X-axis and Y-axis motor 21,22 and the driving arrangement supply capability such as actuator 23.
In addition, be equipped with at the second control substrate 60: motor driver 61, it is supplied with by the electric power from power supply generative circuit 44, drives X-axis motor 21 and Y-axis motor 22; Peripheral device control CPU(arithmetic processing apparatus) 62, it is controlled X-axis motor 21, Y-axis motor 22 and actuator 23 etc.; Actuator driver 63, it supplies with drive actuator 23 by the electric power from power supply generative circuit 44; And I/O interface 64, it is used for CPU62 is connected with each structure.
In addition, peripheral device control is connected with firing switch by I/O interface 64 and guidance panel 26 with CPU62 and is connected, wherein, this guidance panel 26 is used for operating personnel and carries out various setting inputs for Sewing machines 10, and the beginning of action is made in these firing switch 27 indication inputs.
For the power supply control of being undertaken by this master control part 50, as described later.
Carry out the source power supply 200 that electric power is supplied with from Utilities Electric Co., will exchange the 200V(volt) be supplied to main power circuit 41.
In addition, the electric power that 41 pairs of main power circuits are supplied with from source power supply 200 carry out rectification, supply with respectively the dc source of appropriate voltage to power supply generative circuit 44 and motor driver 42.For example, main power circuit 41 is supplied with dc source about 80V to power supply generative circuit 44, the dc source of supplying with about 300V to motor driver 42.
The supply capability that power supply generative circuit 44 is accepted from main power circuit 41 is transformed to the voltage of the driving of the actuator 23 that is suitable for X-axis motor 21, Y-axis motor 22, each peripheral device with it, supplies with and carry out electric power.
Peripheral device control is with CPU62 and master control part 50 coordinations, and the action of the actuator 23 of X-axis motor 21 and Y-axis motor 22 or peripheral device is controlled, and in addition, the input operation of guidance panel 26, starting switch 27 monitored.
In addition, master control part 50 is carried out following actions control, namely, continue in the situation of stipulated time (t) energising of the drive current of sewing machine electromotor 24 temporarily to be interrupted detecting by voltage monitor 411 to be less than or equal to as the primary voltage of comparing slightly high Second Threshold (lower limit) V02, for example 170V with described first threshold V01.That is, V01＜V02.
Based on flow chart shown in Figure 2, describe the content of power supply control in detail.
Processing in this flow chart is repetition period of stipulating 1ms(millisecond for example) repeat (from finishing to return).This repetition period 1ms is stored among the ROM52 that consists of master control part 50.
In addition, when carrying out for the first time, the count value t that the time that is less than or equal to first threshold V01 is carried out the count value s of timing and the time that is less than or equal to Second Threshold V02 is carried out timing is all since 0 state.
At first, CPU51 judges by voltage detector 411 whether the primary voltage of power supply is less than or equal to first threshold V01(step S1).Then, be less than or equal at primary voltage in the situation of first threshold V01, make 2 count value s, t all increase progressively (step S3).
Then, judge whether the count value s that the time that is less than or equal to first threshold V01 is carried out timing reaches 20(step S5).
Count value s more than or equal to 20 situation under, because repetition period of this processing is 1ms, therefore, the expression primary voltage be less than or equal to first threshold V01 state continuance more than or equal to 20ms, in this case, CPU51 makes sewing machine electromotor 24 stop (step S7).In addition, in the situation that sewing machine electromotor 24 stops in step S7, if do not carry out the recovery action of the regulations such as main power source with Sewing machines 10 accesses again, then can not restart to make.In addition, because sewing machine electromotor 24 stops in step S7, so each count value s, t all are reset.
In addition, in step S5, do not reach at count value s in 20 the situation, process entering step S17.
On the other hand, in step S1, be higher than at the primary voltage that detects by voltage detector 411 in the situation of first threshold V01, count value s is reset (step S9).
And CPU51 judges by voltage detector 411 whether primary voltage is less than or equal to Second Threshold V02(step S11).
Judge that by this be higher than at the primary voltage that detects by voltage detector 411 in the situation of Second Threshold V02, count value t is reset, and, to sewing machine electromotor 24 energisings, sewing machine electromotor 24 is driven (step S13).That is, stopping in the situation of the energising of sewing machine electromotor 24, restarting energising by step S19 described later.Then, end process.
In addition, be less than or equal at primary voltage in the situation of Second Threshold (lower limit) V02 (step S11), make count value t increase progressively (step S15).
And whether the count value t that judgement is carried out timing to the time that is less than or equal to Second Threshold V02 reaches 20(step S17).
Count value t more than or equal to 20 situation under, because the repetition period of this processing is 1ms, therefore, mean primary voltage be less than or equal to Second Threshold V02 state continuance comprise time of the state that is less than or equal to first threshold V01 more than or equal to 20ms().
In this case, CPU51 controls main power circuit 41, makes for the energising of sewing machine electromotor 24 and temporarily interrupts (step S19), end process.In addition, the energising to sewing machine electromotor 24 is herein restarting next time and among the step S13 of the power supply that repeats later on control processing.
Namely, when sewing machine electromotor 24 regular event, the primary voltage of power supply is more than or equal to first threshold V01, Second Threshold V02, by the judgement of step S1, count value s is reset (step S9), in addition, judgement by step S11, count value t is reset, and sewing machine electromotor continues driven.
Processing by above-mentioned flow chart, when Sewing machines drives, the primary voltage of power supply descends, detect (step S11) when being less than or equal to Second Threshold V02, count value t increases progressively (step S15), reach (step S17) at 20 o'clock at count value t, will stop to the energising of sewing machine electromotor stipulated time △ T1(step S19).If primary voltage returns to more than or equal to Second Threshold V02(S11 thus), then to the sewing machine electromotor energising, and count value t is reset (step S13).
On the other hand, voltage drop further occurs, detect (step S1) in the situation that is less than or equal to first threshold V01, count value s, t all increase progressively (step S3), reach (step S5) at 20 o'clock at count value s, stop the electric power supply as mistake and stop, driving halted state (step S7) so that sewing machine electromotor becomes.
Because rapid voltage drop, the count value t of Second Threshold V02 was less than before 20 or equals in the situation of first threshold V01 reaching, t counts to count value, until count value s reaches 20 (step S17), reach at 20 o'clock at count value t, the energising of carrying out above-mentioned stipulated time △ T1 to sewing machine electromotor stops.And, reach at 20 o'clock at count value s, make sewing machine electromotor stop (step S7).
As mentioned above, Sewing machines 10 has: main power circuit 41, and it has the transformer that is connected with external power source; Sewing machine electromotor 24, it is as making the drive source of action; Driving arrangement, it becomes and makes that operation is associated and the drive source (X-axis motor 21, Y-axis motor 22 and actuator 23) that moves; As the power supply generative circuit 44 of auxiliary power circuit, its in the future the electric power of automatic power supply circuit 41 supply with to driving arrangement; And as the master control part 50 of power control part, it is controlled main power circuit 41.Sewing machines 10 also has the voltage detector 411 as voltage detection department, this voltage detector 411 detects the primary voltage of the transformer of main power circuit 41, master control part 50 is less than or equal in the situation of predefined Second Threshold V02 as lower limit at the primary voltage that voltage detector 411 detects, and makes to the predefined dwell time △ T1(1ms of the current stops of sewing machine electromotor 24).That is, Sewing machines 10 is characterised in that, in the moment that in fact sewing machine electromotor 24 does not stop, interrupting the energising to sewing machine electromotor 24.In addition, this dwell time △ T1 is consistent with the above-mentioned repetition period.
As mentioned above, the supply voltage of 10 pairs of source power supply 200 sides of Sewing machines descends and detects, and the temporary transient energising of interrupting to sewing machine electromotor 24, therefore, can make supply voltage decline immediate recovery, avoid the misoperation of X-axis motor 21 or Y-axis motor 22 or actuator 23, perhaps sewing machine electromotor 24 stops.And, can also avoid the minimizing of the circulation timei of the Sewing machines that stopped to cause by sewing machine electromotor 24.In addition, because decline directly detects to supply voltage, therefore, can only when actual generation supply voltage descend, carry out to the interruption processing of the energising of sewing machine electromotor 24, thereby can avoid unnecessary interruption.
And, a plurality of Sewing machiness 10 are accepted environment that electric power supplies with from same source power supply 200 under, even occuring, the supply voltage that the driving by some Sewing machiness causes descends, also can in time tackle, can proceed making of a plurality of Sewing machiness.
In addition, Sewing machines 10 is, 50 pairs of main power circuits 41 of master control part are controlled, the state that is less than or equal to Second Threshold V02 with the primary voltage that detects at voltage detector 411 has passed through in the situation of stipulated time (being 20ms in above-mentioned example), and making to the predefined dwell time △ T1(of the current stops of sewing machine electromotor 24 is 1ms in above-mentioned example).
Thus, can avoid causing that owing to producing noise in the detected supply voltage voltage drop carries out situation about processing to the interruption of the energising of sewing machine electromotor 24, can take suitable reply.
In addition, in the above-described embodiment, illustration the electronic circulation sewing machine for sewing, but so long as have sewing machine electromotor and make in the Sewing machines of actuator of subsidiary any action, no matter which kind of form Sewing machines is, above-mentioned power supply control can be used.Therefore, the driving arrangement that becomes the drive source of action subsidiary in making of the present invention is as long as have in X-axis motor, Y-axis motor or the actuator at least one.
In addition, for first threshold (stopping a reference value) V01 or Second Threshold (lower limit) V02, be not limited to the example of above-mentioned value.For example, first threshold V01 can be that voltage value minimum in the scope of misoperation does not occur the actuator except the sewing machine electromotor that Sewing machines has, the mode of Second Threshold V02 distinguishing clearly and detect with first threshold V01 is preferably higher than first threshold V01 within the specific limits voltage value.
Because motion flow shown in Figure 2 repeated with the repetition period (1ms) of regulation, therefore, be less than or equal to Second Threshold (lower limit) V02(and for example be made as 170V) detected state continued the stipulated time situation, to the energising dwell time △ T1 of sewing machine electromotor, consistent with this repetition period.
Repetition period 1ms is stored among the ROM52 that consists of master control part 50.Also can replace, will be stored in the repetition period among the EEPROM54, set change from guidance panel 26.
In addition, when detecting the primary voltage that is less than or equal to Second Threshold (lower limit) V02, interrupt the time (energising dwell time △ T1) to the energising of sewing machine electromotor 24, be not limited to above-mentioned numerical value.For example, also can be set as and be less than or equal to the maximum duration that in sewing machine electromotor 24, do not have abnormal sound or vibration and more than or equal to the time range of the shortest time that supply voltage is descended recover.That is, can be set to make supply voltage to descend (decline of primary voltage) recover the shortest time≤do not have the maximum duration of abnormal or vibration in △ T1≤sewing machine electromotor 24.
