[0055] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0056] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, inside, outside, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0057] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0058] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0059] In existing technologies, some paper conveying devices do not have paper detection functions, while others that do use infrared sensors or microphones to detect paper status. However, both of these methods are reactive. Because these devices cannot monitor paper status in real time, they cannot promptly correct or stop conveying when problems such as paper jams, paper misalignment, or paper damage occur. This can easily lead to irreversible consequences, such as malfunctions of the paper conveying device, causing paper conveying to stop before repairs are completed.

[0060] Therefore, some embodiments of the present invention provide a control method for a paper conveying device 600. In these embodiments, the paper conveying device 600 can convey paper; specifically, it can convey paper from its inlet 610 to its outlet 620. In these embodiments, the paper conveying device 600 can be a paper feeding device, a paper output device, or other mechanisms capable of conveying paper; the present invention does not limit this.

[0061] In this embodiment of the invention, the paper conveying device 600 may be equipped with a detection component, which can be used to detect displacement information during paper movement; see reference. Figure 1 As shown, the control method may include:

[0062] Step S101: When the paper is being conveyed by the paper conveying device 600, the displacement information of the paper is obtained.

[0063] Step S102: Control the paper conveying device 600 to continue operating or stop operating based on the displacement information and displacement reference information.

[0064] In this embodiment of the invention, the paper conveying device 600 can pre-plan the paper's movement route and drive the paper to move along that route, thereby achieving directional accuracy in paper transport. It is understood that during the movement of paper along a predetermined route, various factors can cause issues such as skewing and paper jams. When such situations occur, the paper conveying channel becomes blocked, affecting the transport of subsequent paper. In more serious cases, it can lead to irreversible malfunctions of the paper conveying device 600, requiring significant time for repair and impacting the continuity of paper transport. Therefore, this embodiment of the invention uses a detection component to detect the displacement information of the paper during movement, thereby monitoring the paper's status in real time, anticipating potential adverse consequences, and correcting problems promptly. In this embodiment, the detection component may include a camera device or a sensing component; those skilled in the art can choose the appropriate configuration based on actual conditions, and this embodiment does not limit this choice.

[0065] In this embodiment of the invention, displacement information may include data representing the current position of the paper, and may also include data representing the current direction of paper movement. Specifically, displacement information may be a combination of coordinate information and direction information, or it may be vector coordinates; this embodiment of the invention does not limit this. This embodiment obtains the current state of the paper by acquiring its displacement information and comparing it with displacement reference information. The current state of the paper may include its movement direction state, movement speed state, paper integrity state, etc.; this embodiment of the invention does not limit this. Based on this, the displacement reference information may be displacement information detected at various time points during the normal paper transport process, as measured in advance.

[0066] In this embodiment of the invention, adaptive control can be performed on the current state of the paper after confirmation, improving the controllability of the paper conveying device 600. Specifically, when the paper is confirmed to be in an abnormal state, the paper conveying device 600 can be controlled to stop operation. It should be noted that an alarm can be issued after the paper conveying device 600 stops operation to notify personnel to inspect or repair it. When the paper is confirmed to be in a normal state, the paper conveying device 600 can be controlled to continue operation.

[0067] In this embodiment of the invention, the paper conveying device 600 may be provided with a first controller and a second controller. The first controller can be used to control the start and stop of the paper conveying device 600, and the second controller can be connected to the detection component and the first controller respectively. The control method is applied to the second controller and may include:

[0068] Step S1021: Receive displacement information from the detection component.

[0069] Step S1022: Compare the displacement information and the displacement reference information to determine whether the paper is in an abnormal state.

[0070] In this embodiment of the invention, the second controller can be electrically connected to the detection component. Specifically, it can be connected via a network signal or directly via a wire. Those skilled in the art can choose the appropriate setting based on the actual situation, and this embodiment does not limit this. After receiving the paper displacement information acquired by the detection component, the second controller compares the displacement information with displacement reference information to confirm whether the paper is in an abnormal state. In this embodiment of the invention, the displacement reference information can be stored in the second controller.

[0071] Step S1023: When the paper is in an abnormal state, a stop operation command is sent to the first controller.

[0072] In this embodiment of the invention, when the second controller confirms that the paper is in an abnormal state, it can send a stop operation command to the first controller, thereby notifying the first controller to control the paper conveying device 600 to stop conveying paper. Conversely, when the second controller confirms that the paper is in a normal state, the second controller can not intervene in the first controller, thereby allowing the first controller to control the paper conveying device 600 to continue operating.

[0073] The paper conveying device 600 disclosed in this embodiment of the invention is equipped with a detection component for detecting displacement information during paper movement. The control method acquires the paper displacement information when the paper conveying device 600 conveys paper; and controls the paper conveying device 600 to continue or stop operation based on the displacement information and displacement reference information. This achieves real-time monitoring of the paper status, thereby determining whether the paper status is normal. Furthermore, by monitoring the paper status in real time, the paper conveying device 600 can be dynamically controlled to continue or stop operation based on the current paper status, realizing feedback adjustment control of the paper conveying device 600. When abnormal paper conditions occur, paper conveying can be detected and stopped in a timely manner, reducing the possibility of more serious or irreversible consequences. This not only reduces the risk of paper conveying device 600 failure and extends the service life of the device, but also maintains the continuity of paper output and improves paper output efficiency. In addition, it improves the paper output quality, thereby improving the reliability and safety of the paper conveying device 600, reducing the possibility of paper waste, and saving costs.

[0074] Some embodiments of the present invention provide another control method for the paper conveying device 600, see reference. Figure 6 As shown, in this embodiment of the invention, the paper conveying device 600 may be equipped with a detection component, which can be used to detect displacement information when the paper moves. The detection component may include a first sensor 630, which can be configured to acquire multiple state images of the paper at different positions along the movement trajectory when the paper moves. It should be noted that the first sensor 630 can acquire state images of the paper at different positions in chronological order, thereby acquiring all state images of the paper during its movement along the trajectory and forming a state atlas. In this embodiment of the invention, the displacement information may include a first offset value; the displacement reference information may include a first preset tolerance value. (Refer to...) Figure 2 As shown, the control method may include:

[0075] Step S201: When the paper is being conveyed by the paper conveying device 600, the first state diagram and the second state diagram of the paper are acquired sequentially.

[0076] It should be noted that, in this embodiment of the invention, the second state diagram can be a state image that is later than the first state diagram in chronological order, that is, the second state diagram can be a state image obtained after the paper has moved to the position corresponding to the first state diagram.

[0077] Step S202: Determine the first offset value of the paper based on the first state diagram and the second state diagram.

[0078] This invention allows for the determination of a first offset value of the paper by comparing a first state diagram and a second state diagram. The first offset value represents the degree of paper offset relative to a predetermined transport path. This invention enables real-time monitoring of the paper by confirming its offset.

[0079] In this embodiment of the invention, the displacement information may include first current position information and second current position information, and the displacement reference information may include first predicted position information and second predicted position information; step S202 may include:

[0080] Step S2021: Obtain the first current position information of the paper according to the first state diagram.

[0081] Step S2022: Obtain the first displacement based on the first current position information and the first prediction information.

[0082] It is understood that, in this embodiment of the invention, the first current position information can be data representing the current position of the paper when it is at the position corresponding to the first state diagram, while the first prediction information can be data representing the position of the paper after it has ideally moved along a predetermined route at the same point in time as the first state diagram. This embodiment of the invention can determine the first displacement of the paper by comparing the first current position information and the first prediction information. The first displacement value can represent the distance the paper has deviated from the predetermined transport route.

[0083] Step S2023: Obtain the second current position information of the paper according to the second state diagram.

[0084] Step S2024: Obtain the second displacement based on the second current position information and the second prediction information.

[0085] It is understood that, in this embodiment of the invention, the second current position information can be data representing the current position of the paper when it is at the position corresponding to the second state diagram, while the second prediction information can be data representing the position of the paper after it has ideally moved along a predetermined route at the same point in time as the second state diagram. This embodiment of the invention can determine the second displacement of the paper by comparing the second current position information and the second prediction information. The second displacement value can represent the distance the paper has deviated from the predetermined transport route.

[0086] Step S2025: Calculate the absolute value of the difference between the second displacement and the first displacement to obtain the first offset value.

[0087] In this embodiment of the invention, the first offset value can be the absolute value of the difference between the second displacement and the first displacement, that is, the first offset value can be the data obtained by superimposing or canceling the distance of the paper offset in the first state diagram and the distance of the paper offset in the second state diagram.

[0088] Step S203: Determine whether the first offset value is greater than the first preset tolerance value.

[0089] In this embodiment of the invention, the first preset tolerance value may be a pre-set maximum allowable offset value, and the first preset tolerance value may be used as a benchmark for judging the paper condition.

[0090] In this embodiment of the invention, when the first offset value is greater than the first preset tolerance value, step S204 is executed; when the first offset value is not greater than the first preset tolerance value, step S205 is executed.

[0091] Step S204: Control the paper conveying device 600 to stop operating.

[0092] It is understood that in this embodiment of the invention, when the first offset value is greater than the first preset tolerance value, it indicates that the paper has exceeded the maximum allowable offset, and the continued operation of the paper conveying device 600 needs to be stopped to prevent irreversible consequences.

[0093] Step S205: Control the paper conveying device 600 to continue operating.

[0094] It is understood that in this embodiment of the invention, when the first offset value is not greater than the first preset tolerance value, it indicates that the paper has not shifted or has shifted but has not exceeded the maximum permissible offset degree, and it is not necessary to stop the continued operation of the paper conveying device 600.

[0095] The paper conveying device 600 disclosed in this embodiment of the invention is equipped with a detection component for detecting displacement information when the paper moves. The detection component includes a first sensor 630, which can be configured to acquire multiple state images of the paper at different positions in the movement trajectory when the paper moves. The control method acquires a first state image and a second state image of the paper sequentially; determines a first offset value of the paper based on the first and second state images; determines whether the first offset value is greater than a first preset tolerance value; when the first offset value is greater than the first preset tolerance value, controls the paper conveying device 600 to stop operating; when the first offset value is not greater than the first preset tolerance value, controls the paper conveying device 600 to continue operating; thus realizing the control of the paper state. Real-time monitoring of the paper's status allows for the determination of whether the paper is in normal condition. Furthermore, by monitoring the paper's status in real time, the paper conveying device 600 can be dynamically controlled to continue or stop operation based on the current state of the paper. This achieves feedback regulation and control of the paper conveying device 600. When abnormal conditions occur, paper conveying can be detected and stopped in a timely manner, reducing the possibility of more serious or irreversible consequences. This not only reduces the risk of paper conveying device 600 failure and extends the service life of the device, but also maintains the continuity of paper output and improves paper output efficiency. In addition, it improves the quality of paper output, thereby improving the reliability and safety of the paper conveying device 600, reducing the possibility of paper waste, and saving costs.

[0096] Some embodiments of the present invention provide another control method for the paper conveying device 600, see reference. Figure 7 As shown, in this embodiment of the invention, the paper conveying device 600 may be equipped with a detection component, which can be used to detect displacement information when the paper moves. The detection component may include a second sensor 640 and a third sensor 650 spaced apart from the second sensor 640. The paper may have a first detection point corresponding to the second sensor 640 and a second detection point corresponding to the third sensor 650. When the paper moves, the second sensor 640 may be configured to acquire state images of multiple first detection points located at different positions in the movement trajectory, and the third sensor 650 may be configured to acquire state images of multiple second detection points located at different positions in the movement trajectory. It should be noted that the second sensor 640 and the third sensor 650 may be sensors of the same specification and capable of performing the same function. The difference between the second sensor 640 and the third sensor 650 may be that the detection positions are different, that is, they detect the first detection point and the second detection point respectively. The displacement information may include a second offset value and a third offset value; the displacement reference information may include a second preset tolerance value; the reference... Figure 3 As shown, the control methods include:

[0097] Step S301: Sequentially obtain the third state diagram and the fourth state diagram of the first detection point.

[0098] It should be noted that, in this embodiment of the invention, the fourth state diagram can be a state image that is later than the third state diagram in chronological order, that is, the fourth state diagram can be a state image obtained after the paper has moved to the position corresponding to the third state diagram.

[0099] Step S302: Determine the second offset value of the paper based on the third state diagram and the fourth state diagram.

[0100] In this embodiment of the invention, the second offset value of the first detection point can be confirmed by comparing the third state diagram and the fourth state diagram. The second offset value can represent the degree of offset of the first detection point relative to the predetermined transport route.

[0101] Step S303: Sequentially obtain the fifth state diagram and the sixth state diagram of the second detection point.

[0102] It should be noted that, in this embodiment of the invention, the sixth state diagram can be a state image that is later than the fifth state diagram in chronological order, that is, the sixth state diagram can be a state image obtained after the paper has moved to the position corresponding to the fifth state diagram.

[0103] Step S304: Determine the third offset value of the paper based on the fifth state diagram and the sixth state diagram.

[0104] In this embodiment of the invention, the third offset value of the second detection point can be confirmed by comparing the fifth state diagram and the sixth state diagram. The third offset value can represent the degree of offset of the second detection point relative to the predetermined transport route.

[0105] Step S305: Determine whether the second offset value and / or the third offset value are greater than the second preset tolerance value.

[0106] In this embodiment of the invention, when the second offset value and / or the third offset value are greater than the second preset tolerance value, step S306 is executed; when both the second offset value and the third offset value are not greater than the second preset tolerance value, step S307 is executed.

[0107] Step S306: Control the paper conveying device 600 to stop operating.

[0108] It is understood that in this embodiment of the invention, when one of the second offset value and the third offset value is greater than the second preset tolerance value, it indicates that the offset of the first detection point or the second detection point of the paper has exceeded the maximum allowable offset. At this time, the paper has wrinkled on one side, and it is necessary to stop the continued operation of the paper conveying device 600 to prevent irreversible consequences.

[0109] It is understood that in this embodiment of the invention, when both the second offset value and the third offset value are greater than the second preset tolerance value, it indicates that the offset of the first detection point and the second detection point of the paper has exceeded the maximum allowable offset. At this time, the paper has shifted as a whole, that is, the direction of movement is wrong. It is necessary to stop the continued operation of the paper conveying device 600 to prevent irreversible consequences.

[0110] Step S307: Control the paper conveying device 600 to continue operating.

[0111] It is understood that in this embodiment of the invention, when both the second offset value and the third offset value are not greater than the second preset tolerance value, it indicates that the paper has not wrinkled on one side or shifted overall, and it is not necessary to stop the continued operation of the paper conveying device 600.

[0112] The paper conveying device 600 disclosed in this embodiment of the invention is provided with a detection component for detecting displacement information when the paper moves. The detection component includes a third sensor 650 spaced apart from a second sensor 640. The paper has a first detection point corresponding to the second sensor 640 and a second detection point corresponding to the third sensor 650. When the paper moves, the second sensor 640 is configured to acquire state images of multiple first detection points located at different positions in the movement trajectory, and the third sensor 650 is configured to acquire state images of multiple second detection points located at different positions in the movement trajectory. The control method sequentially acquires a third state image and a fourth state image of the first detection point; determines a second offset value of the paper based on the third and fourth state images; sequentially acquires a fifth state image and a sixth state image of the second detection point; determines a third offset value of the paper based on the fifth and sixth state images; determines whether the second offset value and / or the third offset value are greater than a second preset tolerance value; when the second offset value and / or the third offset value are greater than a second preset tolerance value, the control method determines whether the second offset value and / or the third offset value are greater than a second preset tolerance value. If the third offset value is greater than the second preset tolerance value, the paper conveying device 600 is controlled to stop operating; if neither the second nor the third offset value is greater than the second preset tolerance value, the paper conveying device 600 continues to operate. This achieves real-time monitoring of the paper's condition, thereby determining whether the paper has unilateral wrinkles or overall offset. Furthermore, by monitoring the paper's condition in real time, the paper conveying device 600 can be dynamically controlled to continue or stop operating based on the current state of the paper, achieving feedback regulation control of the paper conveying device 600. When abnormal conditions occur, paper conveying can be detected and stopped in a timely manner, reducing the possibility of more serious or irreversible consequences. This not only reduces the risk of paper conveying device 600 malfunctions and extends the device's service life, but also maintains the continuity of paper output and improves paper output efficiency. In addition, it improves the quality of paper output, thereby improving the reliability and safety of the paper conveying device 600, reducing the possibility of paper waste, and saving costs.

[0113] Some embodiments of the present invention provide another control method for the paper conveying device 600, see reference. Figure 7 As shown, in this embodiment of the invention, the paper conveying device 600 may be equipped with a detection component, which can be used to detect displacement information when the paper moves. The detection component may include a third sensor 650 spaced apart from the second sensor 640. The paper may have a first detection point corresponding to the second sensor 640 and a second detection point corresponding to the third sensor 650. When the paper moves, the second sensor 640 may be configured to acquire state images of multiple first detection points located at different positions in the movement trajectory, and the third sensor 650 may be configured to acquire state images of multiple second detection points located at different positions in the movement trajectory. The displacement information may include a second offset value and a third offset value; the displacement reference information may include a second preset tolerance value and a third preset tolerance value; the reference... Figure 4 As shown, the control methods include:

[0114] Step S401: Sequentially obtain the third state diagram and the fourth state diagram of the first detection point.

[0115] Step S402: Determine the second offset value of the paper based on the third state diagram and the fourth state diagram.

[0116] Step S403: Sequentially obtain the fifth state diagram and the sixth state diagram of the second detection point.

[0117] Step S404: Determine the third offset value of the paper based on the fifth state diagram and the sixth state diagram.

[0118] It should be noted that for the specific implementation of the embodiments of the present invention, please refer to the description of the foregoing embodiments, which will not be repeated here.

[0119] In this embodiment of the invention, when the second offset value and / or the third offset value is greater than the second preset tolerance value, or the absolute value of the difference between the second offset value and the third offset value is greater than the third preset tolerance value, step S405 is executed; when both the second offset value and the third offset value are not greater than the second preset tolerance value, and the absolute value of the difference between the second offset value and the third offset value is not greater than the third preset tolerance value, step S406 is executed.

[0120] Step S405: Control the paper conveying device 600 to stop operating.

[0121] It is understood that, in this embodiment of the invention, when either the second offset value or the third offset value is greater than the second preset tolerance value, it indicates that the offset of the first or second detection point of the paper has exceeded the maximum permissible offset. When both the second and third offset values ​​are greater than the second preset tolerance value, it indicates that the offset of both the first and second detection points of the paper has exceeded the maximum permissible offset. When the absolute value of the difference between the second and third offset values ​​is greater than the third preset tolerance value, it indicates that the change in the relative distance between the first and second detection points of the paper exceeds the maximum permissible value. At this point, the paper has deformed, and the continued operation of the paper conveying device 600 needs to be stopped to prevent irreversible consequences.

[0122] Step S406: Control the paper conveying device 600 to continue operating.

[0123] It is understood that in this embodiment of the invention, when both the second offset value and the third offset value are not greater than the second preset tolerance value, and the absolute value of the difference between the second offset value and the third offset value is not greater than the third preset tolerance value, it indicates that the paper has neither unilateral wrinkling nor overall offset, nor overall deformation, or has undergone overall deformation but has not exceeded the maximum permissible degree of deformation, and it is not necessary to stop the continued operation of the paper conveying device 600.

[0124] The paper conveying device 600 disclosed in this embodiment of the invention is provided with a detection component for detecting displacement information when the paper moves. The detection component includes a third sensor 650 spaced apart from a second sensor 640. The paper has a first detection point corresponding to the second sensor 640 and a second detection point corresponding to the third sensor 650. When the paper moves, the second sensor 640 is configured to acquire state images of multiple first detection points located at different positions in the movement trajectory, and the third sensor 650 is configured to acquire state images of multiple second detection points located at different positions in the movement trajectory. The control method sequentially acquires a third state image and a fourth state image of the first detection point; determines a second offset value of the paper based on the third and fourth state images; sequentially acquires a fifth state image and a sixth state image of the second detection point; determines a third offset value of the paper based on the fifth and sixth state images; when the second offset value and / or the third offset value is greater than a second preset tolerance value, or the absolute value of the difference between the second offset value and the third offset value is greater than the third preset tolerance value, the control... The paper conveying device 600 stops operating; when both the second and third offset values ​​are not greater than the second preset tolerance value, and the absolute value of the difference between the second and third offset values ​​is not greater than the third preset tolerance value, the paper conveying device 600 is controlled to continue operating; this achieves real-time monitoring of the paper's condition, thereby determining whether the paper has unilateral wrinkles, overall offset, or overall deformation; furthermore, by monitoring the paper's condition in real time, the paper conveying device 600 can be dynamically controlled to continue or stop operating based on the current state of the paper, realizing feedback regulation control of the paper conveying device 600. When abnormal conditions occur in the paper, paper conveying can be detected and stopped in time, reducing the possibility of more serious or irreversible consequences. This not only reduces the risk of paper conveying device 600 failure and extends the service life of the device, but also maintains the continuity of paper output and improves paper output efficiency; in addition, it improves the quality of paper output, thereby improving the reliability and safety of the paper conveying device 600, reducing the possibility of paper waste, and saving costs.
