Background
The transfer belt is an important image forming member in an image forming apparatus. The image forming apparatus transfers an image onto a transfer belt, and transfers the image into an image forming medium through the transfer belt, thereby forming an image on the image forming medium. In the above image forming process, the image forming apparatus rotates the transfer belt by the motor, and the rotational speed of the transfer belt is equal to the rotational speed of the motor by default.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, a schematic structural diagram of an image forming apparatus according to an embodiment of the present application is provided. As shown in fig. 1, the image forming apparatus includes a control section, an image forming section, a sensor section, and a storage section. The image forming part, the sensor part and the storage part are all electrically connected with the control part. The control section is a main control unit of the image forming apparatus for controlling the image forming section, the sensor section, and the storage section. The storage component stores program instructions for being executed by the control component, intermediate data required by the program instructions in the running process, data acquired by the sensor component and the like, so that the control component can call and run. The image forming section is configured to execute an image forming job under the control of the control section.
In some embodiments, as shown in fig. 2, the image forming member may include a laser scanning unit (Laser Scanning Unit, LSU), a photosensitive member, a transfer belt, and the like. Alternatively, the photosensitive member may be a photosensitive drum. The sensor components may include color toner density (Color Toner Density, CTD) sensors, and the like. As shown in fig. 2, the CTD sensor may be disposed at a preset position of the transfer belt, such as a C point position shown in fig. 2. The CTD sensor may be used to detect the toner concentration of an image formed on the transfer belt.
Referring to fig. 1 and 2, the process of the image forming apparatus performing an image forming job may include: the control part plays the industry image. In response to the job image issued by the control part, the LSU emits laser light onto the photosensitive drum, and an electrostatic latent image of the job image is formed on the photosensitive drum surface. Further, by supplying the developer to the electrostatic latent image, a visible image can be formed on the photosensitive drum surface. The visible image formed on the surface of the photosensitive drum is used for transfer onto the transfer belt. The image on the transfer belt may then be transferred to an imaging medium to thereby form an image on the imaging medium.
In connection with the above-described image forming process, an embodiment of the present application provides a control method of an image forming apparatus. In the method, a detection image is preset, and the actual rotation speed of the transfer belt is obtained by detecting the transmission time and the transmission distance of the image on the image carrier. Alternatively, the image carrier may be the photosensitive member and/or the transfer belt described above. The deviation from the target rotational speed can be determined from the actual rotational speed of the transfer belt, and the rotational speed of the transfer belt can be adjusted and controlled based on the deviation. The control method of the image forming apparatus of the present application will be described in detail with reference to specific embodiments.
Referring to fig. 3, a flowchart of a control method of an image forming apparatus according to an embodiment of the present application is provided. The main execution body of the method shown in fig. 3 is the control unit described above. As shown in fig. 3, the processing steps of the method include:
the actual rotational speed of the transfer belt is determined 201 based on the conveyance time and the conveyance distance of the detection image on the image carrier.
In some embodiments, the detected image is a preset image, and the detected image may be an image specifically used for performing the speed adjustment of the transfer belt.
In some embodiments, the image carrier may include a photosensitive member and/or a transfer belt. Alternatively, the photosensitive member may be a photosensitive drum. In some examples, the image carrier includes a transfer belt, i.e., the actual rotational speed of the transfer belt is determined based on the conveyance time and the conveyance distance of the detected image on the transfer belt. In some examples, the image carrier includes a photosensitive drum, i.e., the actual rotational speed of the photosensitive drum is determined based on the transfer time and transfer distance of the detected image on the photosensitive drum. The actual rotational speed of the transfer belt is calculated from the actual rotational speed of the photosensitive drum, for example, the actual rotational speed of the photosensitive drum is equivalent to the actual rotational speed of the transfer belt.
In some examples, the image carrier includes a photosensitive drum and a transfer belt, i.e., the actual rotational speed of the transfer belt is determined based on a transfer distance and a transfer time for transferring the detected image from a first position of the photosensitive drum to a second position of the transfer belt. In this example, the error between the rotational speed of the photosensitive drum and the rotational speed of the transfer belt is negligible. In this example, the first position and the second position may be preset. Alternatively, a CTD sensor may be provided at the second position for detecting a detection image on the transfer belt. Specifically, the control section issues a detection image, which is transferred onto the transfer belt via the first position of the photosensitive drum. The transfer belt rotates, and the detection image is detected by the CTD sensor when it is transferred to the second position of the transfer belt. Since the positions of the photosensitive drum and the CTD sensor are fixed, the conveyance distance at which the detection image is conveyed from the first position of the photosensitive drum to the second position of the transfer belt is fixed, and the conveyance time at the conveyance distance can be detected or calculated. The actual rotation speed of the transfer belt can be determined based on the conveyance distance and the conveyance time of the detected image.
202, it is determined whether a first difference between the actual rotation speed of the transfer belt and the target rotation speed is within a preset error range. If so, no adjustment of the actual rotational speed of the transfer belt is required. If not, go to step 203.
After the control part acquires the actual rotation speed of the transfer belt, the control part compares the actual rotation speed of the transfer belt with the target rotation speed. If the first difference between the actual rotation speed of the transfer belt and the target rotation speed is within a preset error range, the deviation between the actual rotation speed of the transfer belt and the target rotation speed is within an allowable range, and the actual rotation speed of the transfer belt is not required to be adjusted. If the first difference between the actual rotation speed of the transfer belt and the target rotation speed is not within the preset error range, the deviation between the actual rotation speed of the transfer belt and the target rotation speed is beyond the allowable range, and the actual rotation speed of the transfer belt needs to be adjusted. Optionally, the step of adjusting the rotational speed of the transfer belt is referred to as 203.
203, adjusting the motor rotation speed for controlling the rotation speed of the transfer belt according to the first difference value.
In an image forming apparatus, rotation of a transfer belt is controlled by a motor. In this step, the purpose of adjusting the rotational speed of the transfer belt is achieved by adjusting the rotational speed of a motor for controlling the rotational speed of the transfer belt, thereby making the actual rotational speed of the transfer belt more approximate to the target rotational speed.
Alternatively, the target rotation speed may be a rotation speed of the motor for controlling the rotation speed of the transfer belt before adjustment. When the rotation speed of the transfer belt needs to be adjusted, the target rotation speed of the motor can be adjusted on the basis of the first difference value, so that the actual rotation speed of the transfer belt is more approximate to the target rotation speed.
Referring to fig. 4, a flowchart of a control method of another image forming apparatus according to an embodiment of the present application is provided. The main execution body of the method shown in fig. 4 is a control part. As shown in fig. 4, the processing steps of the method include:
301, the control section issues a detection image.
302, the control section drives the LSU, and laser light emitted from the LSU is irradiated to a first position on the photosensitive drum, such as a point a position in fig. 2.
303, the detected image at the first position is transferred to the B point position on the transfer belt by the rotation of the photosensitive drum.
304, the rotation-detected image via the transfer belt reaches a second position, such as the C-point position in fig. 2, at which the CTD sensor detects the detected image on the transfer belt.
In steps 301 to 304, the transmission distance of the detected image on the transfer belt may be equivalent to: the distance that the image is transferred from the first position of the photosensitive drum to the second position of the transfer belt, that is, the distance that the image passes from point a to point C through point B, is detected. Alternatively, because the setting positions of the point a, the point B and the point C are fixed, the distance from the point a to the point C through the point B is also fixed, and is denoted as S. It can be understood that the transmission distance of the detected image from the point a to the point C through the point B is S.
In steps 301-304, the transfer time of the detected image on the transfer belt may be equivalent to: the transfer time of the image from the first position of the photosensitive drum to the second position of the transfer belt, that is, the transfer time T of the image from the point a through the point B to the point C is detected.
In some embodiments, the time at which the control unit issues the detected image to the first position (i.e., point a) of the photosensitive drum is denoted as T0, and the time at which the CTD sensor detects the detected image at the second position (i.e., point C) of the transfer belt is denoted as T1. The transfer time of the detection image on the transfer belt can be noted as t=t1 to T0.
In some embodiments, the time T0 at which the control unit issues the detection image to the first position (i.e., point a) of the photosensitive drum may also be understood as the time at which the control unit transmits the laser light to point a through the LSU.
In some embodiments, the control component activates the CTD sensor when issuing a detected image to a first location (i.e., point a) of the photoreceptor drum, i.e., when the LSU emits laser light to point a. When the CTD sensor detects a detection image on the transfer belt, the control section determines the operation time period of the CTD sensor. This operation time period is used to indicate the transfer time T for the detected image to be transferred from the first position (i.e., point a) of the photosensitive drum to the second position (i.e., point C) of the transfer belt.
In some embodiments, the LSU activates the CTD sensor when it emits laser light to the a-spot. When the CTD sensor detects a detection image on the transfer belt, the number N of data that the CTD sensor has acquired is determined. And determining the transmission time T of the detection image from the point A to the point C through the point B according to the data number N and the data acquisition period T of the CTD sensor.
305, the control section calculates the actual rotation speed V1 of the transfer belt based on the conveyance distance S and the conveyance time T of the detected image on the transfer belt. v1=s/T. In the embodiment of the application, the photosensitive drum and the transfer belt are regarded as a whole, so that the measured speed V1 can be regarded as the actual rotation speed of the transfer belt by neglecting the rotation speed error between the photosensitive drum and the transfer belt.
306, the control section determines whether or not the first difference between the actual rotation speed V1 of the transfer belt and the target rotation speed is within a preset error range. If so, no adjustment of the actual rotational speed of the transfer belt is required. If not, step 307 is performed.
307, the control section adjusts the motor rotation speed for controlling the rotation speed of the transfer belt based on the first difference value.
In the embodiment of the application, the control part presets the detection image, and presets the first position and the second position on the photosensitive drum and the transfer belt. When the CTD sensor detects the detection image on the transfer belt, the control part may determine a transmission distance of the detection image according to the preset first position and second position, and may learn a transmission time of the detection image. Based on the conveyance distance and the conveyance time, the control section may determine the actual rotation speed of the transfer belt. The rotational speed of the transfer belt can be adjusted and controlled according to the deviation between the actual rotational speed of the transfer belt and the target rotational speed, so that the actual rotational speed of the transfer belt is more approximate to the target rotational speed.
Referring to fig. 5, a flowchart of a control method of still another image forming apparatus according to an embodiment of the present application is provided. The main execution body of the method shown in fig. 5 is a control part. As shown in fig. 5, the processing steps of the method include:
the control unit issues 401 a detection image.
402, the control unit drives the LSU, and the CTD sensor is activated when laser light emitted from the LSU is irradiated to a first position on the photosensitive drum, such as a point a in fig. 2. Optionally, after the control component issues the detection image, the detection image is transferred to the second position of the transfer belt through the first position of the photosensitive drum, and the second position of the transfer belt is provided with a CTD sensor, which can be used to detect the detection image on the transfer belt. The specific process may be referred to in the description of fig. 4, and will not be described herein.
403, the control section analyzes the data collected by the CTD sensor to determine whether the CTD sensor detects a detection image on the transfer belt. If yes, go to step 404. If not, the control unit continues to acquire the data acquired by the CTD sensor and continues to step 403.
Optionally, the data acquisition period of the CTD sensor is t, that is, the CTD sensor acquires data once every time t. In the case where there is no detected image on the transfer belt, the value detected by the CTD sensor is the background voltage. When the transfer belt has a detected image, the CTD sensor detects a value smaller than the background voltage. When the data collected by the CTD sensor includes a value smaller than the background voltage, the control section determines that the CTD sensor detects the detection image on the transfer belt.
404, the control section determines the number N of data that the CTD sensor has acquired when the CTD sensor detects the detection image on the transfer belt.
405, the control unit determines the transmission time T of the detected image according to the number N of data and the data acquisition period T of the CTD sensor.
406, the control part calculates the actual rotation speed v1=s/T of the transfer belt based on the conveyance distance S and the conveyance time T. Optionally, the transmission distance of the detected image from the first position to the second position is S, and specifically, refer to the related description of fig. 4, which is not described herein.
407, the control section determines whether or not the first difference between the actual rotation speed V1 of the transfer belt and the target rotation speed V0 is within a preset error range. If so, no adjustment of the actual rotational speed of the transfer belt is required. If not, go to step 408.
The control section determines 408 a ratio to be adjusted of the motor rotation speed for controlling the rotation speed of the transfer belt based on the first difference and the target rotation speed V0. Alternatively, the ratio to be adjusted Vn% = (|v1-v0|v0) of the motor rotation speed for controlling the rotation speed of the transfer belt.
409, the control part adjusts the motor rotation speed for controlling the rotation speed of the transfer belt according to the ratio to be adjusted. Alternatively, the motor-adjusted rotation speed may be v× (1±vn%), where V may be the current rotation speed of the motor for controlling the rotation speed of the transfer belt.
In the embodiment of the application, the transmission time of the detection image on the transfer belt can be determined by the number of data acquired by the CTD sensor. The embodiment of the application can adjust the rotating speed of the motor in a proportional adjustment mode, thereby achieving the purpose of adjusting the rotating speed of the transfer belt.

In order to detect the two rectangular color patches, two CTD sensors for detecting one rectangular color patch may be symmetrically disposed at the C point of the transfer belt, respectively.
Referring to fig. 7, a schematic diagram of another detection image according to an embodiment of the present application is provided. As shown in fig. 7, the detection image for calculating the actual rotation speed of the transfer belt may be a rectangular patch. Alternatively, the rectangular patch may be any one of four colors of CMYK. As shown in fig. 7, the length direction of the one rectangular patch is parallel to the scanning direction, and the width direction of the one rectangular patch is parallel to the conveying direction of the transfer belt. Alternatively, the two wide sides of the rectangular color patch are equidistant from the edge of the transfer belt along the length direction of the rectangular color patch, i.e., the rectangular color patch is disposed at the width center position of the transfer belt. In order to detect the rectangular patch, a CTD sensor may be provided at the C point of the transfer belt, and the CTD sensor may be provided at the widthwise center position of the transfer belt for detecting the rectangular patch shown in fig. 7.
