Specific embodiment
Hereinafter, the preferred embodiment of the present invention is described in detail based on attached drawing.In addition, for those skilled in the art For member, it can be realized their a variety of alternatives under the enlightenment of these embodiments, moreover, the present invention is not limited thereto Locate the preferred embodiment of explanation.
Fig. 1 is the schematic diagram for indicating clutch working principle.As shown in Figure 1, the transmission system in power supply device has: horse Up to 101, the gear set 102 that is connect with motor 101, connect with gear set 102 as interconnecting piece clutch 103, pass through to The axis 104 and one for such as metal material that clutch 103 is powered or powered off and connects or disconnects relative to clutch 103 It is set to the roller 105 of axis 104.
If motor 101 starts and exports rotation, clutch 103 is via gear set 102 and as motor 105 revolves together Turn.At this point, clutch 103 generates magnetism because of electromagnetic induction principle and attracts axis 104 if powering to clutch 103, thus Axis 104 is connect with clutch 103, and axis 104 and roller 105 rotate together with clutch 103.At this point, if disconnecting to clutch 103 power supply, then magnetic to disappear, axis 104 and clutch 103 disconnect, so that axis 104 and roller 105 stall.
Fig. 2 is the schematic diagram for indicating clutch driving circuit.As shown in Fig. 2, clutch driving circuit has: output REM CPU (central processing unit: Central Processing Unit), the TR1 of signal (control signal: Remote Signal) are (brilliant Body pipe: Transistor) and clutch 103.
If CPU exports REM signal, TR1 is opened and clutch is made to work.On the contrary, if CPU does not export REM signal, TR1 is closed and clutch is made to stop working.
In power supply device, controlled by control clutch to various load supplyings.Even if also, also same in MFP Sample uses clutch to control to various load supplyings.
For example, as load ADF registration roller, fixing prelocalization roller, various carrying rollers can be enumerated, for detecting paper Deng sensor, CPU etc..
As the method that powers to the load of control, there is known control clutch, using clutch connection secondary-side circuitry with The method of load, such as the method for control REM.Specifically, by the opening signal and shutdown signal that change REM, to switch State that clutch is fully connected, the state being kept completely separate.
Specifically, as shown in figure 3, REM signal is not exported in the case where being not desired to drive shaft, thus clutch and axis It disconnects and becomes the not state of drive shaft completely.In the case where thinking drive shaft, REM signal is exported, so that clutch and axis connect Connect and become the state of normal drive shaft.For clutch load control, ideally after exporting REM signal, Clutch attracts axis to rotate it with defined speed at once, however actual conditions are needed until clutch attracts axis completely Want the regular hour, i.e., the Connection Time T1 of clutch and axis, in Fig. 3, and the Connection Time T1 that has to be can not It avoids.
Next, being illustrated referring to structure of the Fig. 4 to power supply device of the invention.
As shown in figure 4, power supply device of the invention has: AC power source 201, output AC voltage (such as 220V is handed over Galvanic electricity pressure);Main switch 202 is used to be switched on or switched off AC power source 201;Primary side components 203 are used to receive to be selfed The alternating voltage in galvanic electricity source 201;Rectification circuit 204 is rectified to obtain to the alternating voltage that primary side components 203 receive DC voltage (such as 24V or so DC voltage);Secondary side components 205, via control unit 206 (such as control base board) and Linking part 207 (such as clutch) is to the supply of 208 (such as roller etc.) of load by the DC voltage after the rectification of rectification circuit 204.
Next, being illustrated referring to Fig. 5, Fig. 6 to the specific embodiment for reducing the Connection Time.
For ease of description, the state of normal driving axis is known as first state, by the not state of drive shaft, i.e. electric completely State when pressure is for 0V or without input control signal is known as the third state, will be between first state and the third state State be known as the second state.
< first embodiment >
Fig. 5 is the schematic diagram for indicating the clutch load control of first embodiment of the invention.In the present invention, it loads For example including following mechanism.I.e., as load, including ADF registration roller, fixing prelocalization roller, various carrying rollers, for detecting paper Open equal sensor, CPU etc..
As shown in figure 5, control unit is supplied to the clutch as interconnecting piece in the case where being not desired to axis of the driving as load (i.e., axis attract and the voltage of the critical state without attraction, in other words, right to preset critical voltage V1 The voltage for the critical state that axis will be attracted) and REM signal is not exported, to make at the connection status of clutch and axis In the second state.In the case where thinking driving load, the critical voltage V1 supplied to clutch is promoted to work electricity by control unit Press V2 (in the present invention be, for example, 24V, but not limited to this, can as the case may be such as load type and arbitrarily become REM signal more) and with 100% duty ratio is exported, to make the connection status of clutch and axis from the second state to first State switching.
In the present embodiment, pass through opposite clutch during a job or during continuous work using control unit The service voltage of supply, which is controlled, switches the connection status of clutch from the second state to first state, and by clutch Connection status from the third state directly to first state switch existing situation compare, can be from the angle of control mode Shorten the clutch Connection Time without additional component, productivity is improved while not improving component costs.
It should be noted that clutch is coil component, if applying voltage to it, clutch can be produced because of electromagnetic induction principle Magnetisation and attract axis, and voltage is bigger, and attraction is bigger.Accordingly, there exist to axis carry out attract with without the upper of attraction State critical voltage V1.As described in above-mentioned first embodiment, be not desired to attract axis when apply critical voltage V1 and REM signal is not exported, it is defeated with 100% duty ratio while critical voltage V1 is risen to operating voltage V2 when thinking attraction axis REM signal out, so that compared to existing situation the Connection Time can be shortened from the angle of control mode.
In addition, for making needed for the attended operation of clutch and axis " critical voltage V1 ", it is even identical from Clutch also can be different because of load, place difference.If load is more and/or bigger, critical voltage V1 is also bigger. For example, critical voltage V1 can be set as 10V for ADF registration roller (load is smaller);For agent localization roller (load compared with Greatly), critical voltage V1 can be set as 15V.
Simultaneously as the manufacturing condition of clutch is different and component has differences each other, so being even applied to same The same part in one place, a possibility that changing there is also critical voltage V1.Therefore, to be not necessarily reduced to this critical Voltage V1, it may be considered that given voltage is adjusted according to the requirement of user, i.e., is reduced, in a manner of the affluence having to a certain degree Voltage value (designated value), controls required electric power according to the demand of user as a result, reaches effective control of energy consumption.For example, being directed to Critical voltage can be set to be slightly less than 10V by ADF registration roller, for agent localization roller, critical voltage can be set to omit Less than 15V.
< second embodiment >
Fig. 6 is the schematic diagram for indicating the clutch load control of second embodiment of the present invention.
As shown in fig. 6, control unit is supplied to the clutch as interconnecting piece in the case where being not desired to axis of the driving as load It (is in the present invention, for example, 50%, but it is not limited to this, can be according to specific to operating voltage V2 and with certain duty ratio Situation such as load type changes) pulse output REM signal, so that the connection status of clutch and axis be made to be in the second shape State.In the case where thinking driving load, the duty ratio that control unit keeps output services voltage V2 constant and with 100% is exported REM signal, so that the connection status of clutch and axis be made to switch from the second state to first state.
In the present embodiment, using control unit one work during or continuous work during by control clutch The REM signal of device is controlled the duty ratio of REM signal (control) for the connection status of clutch from the second state to first State switching, similarly to the first embodiment, with by the connection status of clutch from the third state directly to first state The existing situation of switching is compared, and can shorten the clutch Connection Time from the angle of control mode without additional component, Productivity is improved while not improving component costs.
For above-mentioned first embodiment and second embodiment, both sides respectively have advantage and disadvantage.For example, the One embodiment uses voltage-controlled method, does not have to concern EMI (electromagnetic interference: Electro-Magnetic Interference), but circuit is complicated and be unfavorable for energy conservation.In contrast, second embodiment uses pulse controlled side Method, circuit simply (without generating the circuit of the voltage value other than such as 24V) and is conducive to energy conservation, but worries EMI.It should say It is bright, it is talked about if it is the equipment as MFP with battery, then on the contrary need not especially need to consider power saving.
For this purpose, in practical applications, however it is not limited to individually implement above two control method, it can be according to power supply device institute Two kinds of control methods are applied in combination in the state (mode) at place.For example, control unit can lead to when power supply device is in standby The service voltage for crossing opposite clutch supply is controlled and is switched between first state and the second state, is filled in power supply It sets in sleep state (so-called sleep state is exactly the state that machine in-line power is cut off) or power save mode (so-called section comprehensively Can state be main power source cutting inside machine state) when and the REM signal to control clutch controls the It is switched between one state and the second state.So, control mode can be changed according to equipment state, selection is to pass through Control service voltage still shortens the clutch Connection Time by pulse control REM signal, to play two kinds of controls comprehensively The effect of mode.
In addition, as described above, the size of the duty ratio of critical voltage or REM signal be not it is fixed, can basis The type of load is adjusted, i.e., in the second condition, determines to be intended to first state or become according to the type of load To in the third state, for example, being more intended to the third state if voltage needed for driving load is lower.
Specifically, power supply device of the invention has receiving unit, the information about the second state is received from user, Control unit is intended to first state according to the second state of information control about the second state or is intended to not drive completely The state of load.As receiving unit, operation panel can have been enumerated.For example, when MFP is connect by network with various terminals, Smart phone or PC become receiving unit.
In addition, lifting ADF for the concrete application of above-mentioned first embodiment and second embodiment and (removing automatically Send device: Automatic Direction Feeder) it is illustrated for registration roller, in the first state, positioned using ADF Roller transports paper, in the second condition, is adjusted using ADF registration roller to the inclination of paper, after the adjustment from Second state is switched over to first state.Thereby, it is possible to the shape of registration roller is rapidly changed after the inclination for having adjusted paper State shortens the Connection Time of registration roller and clutch.According to test it is found that implementing by above-mentioned first embodiment and second The clutch load control method of mode applied to ADF equipment after the Connection Time can be greatly shortened, by productivity from 55ppm is promoted to 57ppm (opening/minute).
