Example one
As shown in fig. 2, the present embodiment provides a sheet conveyance control apparatus, the control apparatus 200 including;
a stepping motor 202;
a sheet conveyance unit 203 that receives the driving force of the stepping motor 202;
a controller 201 for inputting different control information to the stepping motor based on the received different driving modes;
when the driving mode received by the controller is a normal mode, control signals of a first rotating speed V1 and a first step length M1 are input to the stepping motor; when the driving mode received by the controller is the speed reduction mode, control signals of a second rotating speed V2 and a second step length M2 are input into the stepping motor; and V1> V2, M1< M2.
Specifically, the controller 201 acquires the driving mode of the stepping motor 202, determines the step size of the stepping motor 202 according to the driving mode, determines the speed of the stepping motor 202 to be the first rotation speed V1 and the step size to be the first step size M1 when the driving mode is the normal mode, provides a predetermined first pulse signal to the stepping motor driver 204 as the control signals of the first rotation speed V1 and the first step size M1 input to the stepping motor, and determines the speed of the stepping motor 202 to be the second rotation speed V2 and the step size to be the second step size M2 when the driving mode is the deceleration mode, provides a predetermined second pulse signal to the stepping motor driver 204 as the control signals of the second rotation speed V2 and the second step size M2 input to the stepping motor.
Further, the controller 201 may acquire the driving mode of the stepping motor 202 by analyzing the received information related to the driving mode.
Specifically, the controller 201 can control the frequency, the step angle, the rotation direction, and the like of the stepping motor 202 by the driving pulse. The frequency of the stepping motor 202 is used to determine the rotation speed of the stepping motor 202, the sheet conveyance speed of the sheet conveyance unit 203 corresponds to the rotation speed of the stepping motor 202, the step angle of the stepping motor 202 is used to determine the step size of the stepping motor 202, and the rotation direction of the stepping motor 202 indicates whether the stepping motor 202 is forwarding or reversing.
In this embodiment, the controller 201 may be a Central Processing Unit (CPU) or a System on a Chip (SoC) of the image forming apparatus, or may be a microcomputer including a memory, a processor and/or an Application Specific Integrated Circuit (ASIC), and the Specific form of the controller is not limited in the present invention.
Specifically, the stepping motor driver 204 receives a predetermined first or second pulse signal for driving the stepping motor 202 from the controller 201, subdivides or amplifies the first or second pulse signal in conjunction with a predetermined number of phases of the stepping motor 202 at a speed and a step size corresponding to the first or second pulse signal, and applies a current to each coil of the stepping motor 202 in a predetermined order, so that the stepping motor 202 is controlled at the corresponding step size while being driven at the corresponding speed, thereby controlling the rotational speed and rotational accuracy of the stepping motor 202.
Specifically, the stepping motor 202 is driven by a stepping motor driver 204, and transmits a rotational force to the paper conveyance unit 203. When the driving mode is the normal mode, the stepping motor rotates at a first rotating speed V1 in a first step M1, and when the driving mode is the speed reduction mode, the stepping motor rotates at a second rotating speed V2 in a second step M2, wherein the first step M1 is smaller than the second step M2, and the first rotating speed V1 is greater than the second rotating speed V2.
It should be noted that the stepping motor 202 may be a 2-phase stepping motor or a 3-phase stepping motor; the stepping motor 202 may be a Variable Reluctance (VR) stepping motor, a Permanent Magnet (PM) stepping motor, or a hybrid stepping motor, and the present invention is not limited to the specific type of the stepping motor.
The driving mode may be determined by the type of paper to be printed or the user's setting, and when the driving mode is the normal mode, the paper transport speed is the normal transport speed, and when the driving mode is the reduced speed mode, the paper transport speed is the lower transport speed, i.e., the paper transport speed determines the rotation speed of the stepping motor 202, and thus determines the driving mode of the stepping motor 202. For example, in view of heat dissipation of the heat roller, the sheet conveying speed of the a4 sheet is the normal mode, and the sheet conveying speed of the smaller-sized sheet is the reduced speed mode, and the lower sheet conveying speed in the reduced speed mode is favorable for more sufficient heat dissipation in the sheet-free area of the heat roller; in consideration of fixation firmness, the paper conveying speed of a normal paper type is in a normal mode, the paper conveying speed of thick paper is in a speed reduction mode, and the lower paper conveying speed in the speed reduction mode is favorable for fixation of the carbon powder image on the thick paper; in consideration of noise, the user may select a noise reduction mode in which the paper conveyance speed is a reduced speed mode in which a lower paper conveyance speed is advantageous for reducing noise.
In the present embodiment, the drive step size of the stepping motor 202 is determined according to the drive mode, for example, when the drive mode is the normal mode, the stepping motor is rotated at a normal speed in the half-step drive, and when the drive mode is the reduced speed mode, the stepping motor is rotated at a lower speed in the full-step drive; when the driving mode is a normal mode, the stepping motor rotates at a normal speed under micro-step driving, and when the driving mode is a reduced speed mode, the stepping motor rotates at a lower speed under full-step driving; when the driving mode is the normal mode, the stepping motor is rotated at a normal speed under the micro-step driving, and when the driving mode is the slow-down mode, the stepping motor is rotated at a lower speed under the half-step driving. For example, the microsteps are 1/4, 1/8 or 1/16 steps, and the specific size of the microsteps is not limited by the present invention. The step angles corresponding to the full step, the half step and the micro step are 1, 1/2 and 1/n respectively, wherein n is an integer greater than 2.
In a preferred embodiment of this embodiment, as shown in table 1, when the driving mode is the normal mode, the stepping motor is rotated at a normal speed in the half-step driving, and when the driving mode is the reduced speed mode, the stepping motor is rotated at a lower speed in the full-step driving.
Drive mode Step size
Normal mode Half step length
Deceleration mode Full step size
TABLE 1 Stepper Motor control strategy
In a preferred embodiment of this embodiment, the control is performed in the second speed V2 and the first step length M1 in the deceleration modeThe moment of the stepping motor is T under the signalhalf-step2Maximum current of Ihalf-step2The torque of the stepping motor is T under the control signals of the second rotating speed V2 and the second step length M20Maximum current of I0Then T ishalf-step2＜T0，Ihalf-step2＞I0。
Under the condition that the resistance of the stepping motor circuit is not changed, the relationship between the torque and the maximum current of the stepping motor and the driving mode and the step length is shown in table 2, and when the full-step driving mode is adopted by the stepping motor without setting the normal mode, the torque and the maximum current of the stepping motor are respectively T0And I0. Reasonable selection of motor circuit resistance and step motor torque T0And maximum current I0When the speed-reducing mode stepping motor adopts a full-step driving mode, the torque and the maximum current of the stepping motor are respectively T0And I0It is understood that the intersection of two different curves is (T)0，I0)。
When the normal mode stepping motor adopts the half-step driving mode, the step angle is 1/2 of the basic step angle, the rotation angle is reduced, the rotation is smooth, the amplitude during the rotation is reduced, the vibration of the stepping motor is reduced, the output is more stable, the vibration in the paper conveying process can be reduced, and the noise is reduced at the same time, although the output torque of the half-step driving mode is reduced to Thalf-step1Maximum current rise of Ihalf-step1May be, for example, Thalf-step1＝0.7T0，Ihalf-step1＝1.05I0Since the torque required in the paper transportation process is TrequireLess than Thalf-step1May be, for example, TrequireIs 50-60% T0Further, the maximum rated current of the stepping motor is Irated-currentMay be, for example, Irated-current＝1.4I0At this time, the output torque Thalf-step1Maximum current Ihalf-step1The paper conveyance requirements can still be met.
If the speed reduction mode still adopts half-step driving, even Thalf-step2＝Thalf-step1＝0.7T0Maximum current Ihalf-step2May still exceed the rated maximum current I of the motorrated-currentMay be, for example, Ihalf-step2＝1.45I0Exceeding the rated maximum current I of the motorrated-current＝1.4I0Safety problems may arise. In the deceleration mode, since the speed of the stepping motor is slower than that in the normal mode and the vibration and noise ratio is smaller than that in the normal mode, a full-step driving method can be adopted in the deceleration mode.

TABLE 2 stepping motor Torque and maximum Current dependence on drive mode and step Length
Specifically, the sheet carrying unit 203 is driven by the rotational force transmitted from the stepping motor 202, and carries the sheet. The transmission structure of the rotational force of the stepping motor 202 includes a first sensing gear 205, a second sensing gear 206, a first driving shaft 207, and a second driving shaft 208, the first sensing gear 205 and the second sensing gear 206 are provided between the stepping motor 202 and the sheet conveying unit 203, and the rotational force is transmitted from the stepping motor 202 to the sheet conveying unit 203 by the first driving shaft 207 and the second driving shaft 208, wherein the first driving shaft 207 coaxially connects the stepping motor 202 with the first sensing gear 205, and the second driving shaft 208 coaxially connects the second sensing gear 206 with the sheet conveying unit 203.

By adopting the technical scheme provided by the embodiment, the small step can be corresponded by higher paper conveying speed, the vibration and noise generated in the paper conveying process can be reduced, the image quality is improved, and the noise interference of a user is avoided. The lower paper conveying speed corresponds to a large step length, and compared with a small step length, the driving current of the motor is reduced, so that the energy consumption is reduced, and the running safety of the motor is facilitated. The reduction of vibration and noise generated during the paper sheet conveyance process is achieved by changing the step length of the stepping motor, without increasing additional cost as compared to improving the degree of engagement between gears and gear-related components. Therefore, in different driving modes, the motor can be driven by small current while ensuring low vibration and low noise, and the high quality of the printed image, the high safety of the stepping motor and the low cost of the control device can be simultaneously realized.
