Abstract
Description
Technical Field
[0001] This invention relates to the field of automated assembly technology, specifically to an automatic printing and marking system. Background Technology
[0002] To reduce teachers' workload in grading assignments and tests, automatic grading has emerged. Automatic grading involves digitizing students' assignments or tests using a scanner, then performing data comparison and calculations using a computing module. Finally, the results are printed onto the original assignment or test paper. This not only reduces teachers' workload in grading but also leaves markings on the original paper, facilitating subsequent explanations by teachers and review by students.
[0003] Existing automatic printing trace methods mostly involve first scanning the document with a scanner, performing calculations after scanning, and then placing the document into the printer, which prints according to the calculation results. The entire printing trace process is cumbersome, requires manual operation, is time-consuming and labor-intensive, and is inefficient. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an automatic printing and trace retention system with high work efficiency.
[0005] The technical solution of the present invention is to provide an automatic printing trace system having the following structure:
[0006] The system includes a paper feeding and scanning mechanism, a calculation and waiting mechanism, a printing mechanism, and a calculation module. The paper feeding and scanning mechanism and the printing mechanism are respectively connected to the two ends of the calculation and waiting mechanism. The calculation module is electrically connected to the paper feeding and scanning mechanism, the calculation and waiting mechanism, and the printing mechanism. The paper feeding and scanning mechanism is used to scan documents and then transport them to the calculation and waiting mechanism. At the same time, it transmits the scanned image to the calculation module for calculation. The calculation and waiting mechanism is used to temporarily store the scanned documents. After the calculation module finishes processing the documents, it is transported to the printing mechanism. The printing mechanism prints the documents according to the calculation results of the calculation module.
[0007] With the above structure, the automatic printing trace system of the present invention has the following advantages compared with the prior art:
[0008] This invention integrates a paper feeding scanning mechanism, a printing mechanism, and a computing module, enabling automatic document scanning, processing, and printing without manual operation, saving time and effort. Because the paper feeding scanning mechanism has a fast image scanning speed, while the computing module's processing speed is relatively slow (with a 2-3 second time interval), the scanned document must wait for the computing module to finish its processing before being sent to the printer. This forces the paper feeding scanning mechanism to adjust its scanning speed to match the computing module's speed, significantly reducing the efficiency of the automatic printing mark system. To avoid this, this invention adds a processing waiting mechanism between the paper feeding scanning mechanism and the printing mechanism to temporarily store the document. The paper feeding scanning mechanism does not need to adjust its scanning speed; it can directly send the quickly scanned document to the processing waiting mechanism. The processing waiting mechanism then transmits the document to the printing mechanism for printing after the computing module has finished its processing, thereby improving the efficiency of the automatic printing mark system.
[0009] Preferably, the paper feeding and scanning mechanism includes a scanning channel, a paper feed table, a paper feed module, a scanning module, and a first paper feed module; the paper feed table and the calculation waiting mechanism are respectively disposed at both ends of the scanning channel, the paper feed module is disposed between the paper feed table and the scanning channel, and the scanning module and the first paper feed module are disposed on the scanning channel; the paper feed table is used to carry documents, the paper feed module is used to pick up documents from the paper feed table and transport them to the scanning channel, the first paper feed module is used to drive the documents to move along the scanning channel, and after passing through the scanning module, they are transported to the calculation waiting mechanism, the scanning module is used to scan the documents that have passed through, and transmit the scanned images to the calculation module for calculation.
[0010] Preferably, the paper feeding module includes a paper feed motor, a paper separation motor, a paper feed roller, and a paper separation roller; the paper feed roller and the paper separation roller are disposed between the paper feeding table and the scanning channel, and there is a gap between the paper feed roller and the paper separation roller for the document to pass through; the paper feed motor is driven to the paper feed roller, and the paper separation motor is driven to the paper separation roller; a paper pickup roller and a lifting motor are respectively provided above and below the paper feeding table; the lifting motor is driven to the paper feeding table and is used to drive the paper feeding table to move up and down, so that the document at the top of the paper feeding table abuts against the paper pickup roller; the paper feed motor is driven to the paper pickup roller and is used to drive the paper pickup roller to rotate, and to drive the document at the top of the paper feeding table into the gap between the paper feed roller and the paper separation roller.
[0011] When the document is being reviewed, the lifting motor drives the paper feed table to move upward. The paper feed table is equipped with a lifting top detection sensor and a lifting bottom detection sensor, respectively. The lifting top detection sensor can detect whether the paper feed table has risen to the correct position. After the paper feed table has risen to the correct position, the paper feed motor drives the paper pickup wheel to rotate, and the document at the top of the paper feed table enters the gap between the paper feed wheel and the paper separation wheel. The paper feed wheel and the paper separation wheel, driven by the paper feed motor and the paper separation motor, carry the document into the scanning channel.
[0012] Preferably, the scanning module includes a scanning detection sensor and an image sensor disposed on the scanning channel. The scanning detection sensor is located in front of the image sensor and is used to detect passing documents. The image sensor is used to scan and photograph the passing documents. The image sensor is a CIS image sensor, electrically connected to the processing module, which can transmit the scanned document image to the processing module for processing.
[0013] Preferably, the first paper feeding module includes a first paper feeding motor and a first paper feeding roller group that is drivenly connected to the first paper feeding motor. The first paper feeding roller group consists of multiple rollers that are evenly spaced along the length of the scanning channel.
[0014] Preferably, a skew detection sensor, a left and right extra-wide detection sensor, and an ultrasonic sensor are sequentially provided on the scanning channel between the paper feed module and the scanning module. The skew detection sensor is used to detect whether the orientation of the document is tilted, the left and right extra-wide detection sensor is used to detect whether the document is shifted to the sides, and the ultrasonic sensor is used to detect whether the document overlaps.
[0015] Preferably, the calculation waiting mechanism includes a calculation waiting channel, a second paper feed motor, and a second paper feed roller group. The two ends of the calculation waiting channel are connected to the output end of the paper feeding scanning mechanism and the input end of the printing mechanism, respectively. Multiple second paper feed roller groups are evenly spaced along the calculation waiting channel. The second paper feed motor is driven by the second paper feed roller groups to rotate them. The document scanned by the paper feeding scanning mechanism is transmitted to the printing mechanism along the calculation waiting channel. The time it takes for the document to travel through the entire calculation waiting channel is not less than the time it takes for the calculation module to process the document. This ensures that all documents arriving at the printing mechanism have been processed and can be printed directly.
[0016] Preferably, there are at least two processing waiting channels; a first paper path diversion control motor is provided at the output end of the paper feed scanning mechanism, which controls one of the processing waiting channels to connect with the output end of the paper feed scanning mechanism, so that the document output by the paper feed scanning mechanism enters the processing waiting channel; a second paper path diversion control motor is provided at the input end of the printing mechanism, and a paper arrival detection sensor is provided near the second paper path diversion control motor in each processing waiting channel. When the paper arrival detection sensor detects that a document has passed by, the second paper path diversion control motor controls the processing waiting channel where the paper arrival detection sensor is located to connect with the input end of the printing mechanism, so that the document enters the printing mechanism; a paper jam detection sensor is also provided on the processing waiting channel to detect whether there is a paper jam in the processing waiting channel. Because the scanning speed of the paper feeding scanning mechanism is relatively fast, too many documents will be scanned during the processing time of the calculation module. In order to ensure that the documents on the calculation waiting channel do not overlap, the calculation waiting channel must be long enough, which will cause the entire device to occupy too much space. Therefore, this invention sets up multiple calculation waiting channels. The first paper path diversion control motor can sequentially send the quickly scanned documents into different calculation waiting channels according to the set program. This can greatly shorten the length of a single calculation waiting channel, thereby reducing the overall size of the device.
[0017] Preferably, the printing mechanism includes a printing channel, a third paper feed motor, a third paper feed roller group, and a printing module; one end of the printing channel is connected to a calculation and waiting mechanism, and the other end is connected to the paper output platform; there are multiple third paper feed roller groups, which are evenly spaced along the printing channel; the third paper feed motor is driven by the third paper feed roller groups and is used to drive the third paper feed roller groups to rotate, thereby moving the document along the printing channel; the printing module is set on the printing channel and prints the document that passes through it according to the calculation result of the calculation module.
[0018] Preferably, there are two printing modules, located on opposite sides of the printing channel, for printing both sides of the document. This configuration significantly improves printing efficiency. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0025] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. At the same time, the terms "first," "second," etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship. Therefore, they should not be construed as limitations on this invention.
[0026] like Figure 1 and Figure 2 As shown, this invention discloses an automatic printing trace system, comprising a paper feeding scanning mechanism 1, a calculation waiting mechanism 2, a printing mechanism 3, and a calculation module. The paper feeding scanning mechanism 1 and the printing mechanism 3 are respectively connected to the two ends of the calculation waiting mechanism 2, and the calculation module is electrically connected to the paper feeding scanning mechanism 1, the calculation waiting mechanism 2, and the printing mechanism 3. The paper feeding scanning mechanism 1 is used to scan documents and then transport them to the calculation waiting mechanism 2, while simultaneously transmitting the scanned image to the calculation module for calculation. The calculation waiting mechanism 2 is used to temporarily store the scanned documents. After the calculation module finishes processing the documents, it transports them to the printing mechanism 3, and the printing mechanism 3 prints the documents according to the calculation results of the calculation module.
[0027] This invention integrates the paper feeding scanning mechanism 1, the printing mechanism 3, and the calculation module into one unit, enabling automatic scanning, calculation, and printing of documents without manual operation, saving time and effort. Because the image scanning speed of the paper feeding scanning mechanism 1 is relatively fast, while the calculation speed of the calculation module is relatively slow, there is a 2-3 second time interval. The scanned document needs to wait for the calculation module to finish its calculation before it can be sent to the printer for printing. This forces the image scanning speed of the paper feeding scanning mechanism 1 to be adjusted to match the calculation speed of the calculation module, significantly reducing the efficiency of automatic printing and trace retention. To avoid this situation, this invention adds a calculation waiting mechanism 2 between the paper feeding scanning mechanism 1 and the printing mechanism 3 for temporarily storing documents. The paper feeding scanning mechanism 1 does not need to adjust its image scanning speed and can directly send the quickly scanned document to the calculation waiting mechanism 2. The calculation waiting mechanism 2 will then transfer the document to the printing mechanism 3 for printing after the calculation module has finished its calculation, thereby improving the efficiency of the automatic printing and trace retention system.
[0028] The paper feeding and scanning mechanism 1 includes a scanning channel 11, a paper feed table 12, a paper feed module 13, a scanning module 14, and a first paper feed module 15. The paper feed table 12 and the calculation waiting mechanism 2 are respectively disposed at both ends of the scanning channel 11. The paper feed module 13 is disposed between the paper feed table 12 and the scanning channel 11. The scanning module 14 and the first paper feed module 15 are disposed on the scanning channel 11. The paper feed table 12 is used to carry documents. The paper feed module 13 is used to pick up documents from the paper feed table 12 and transport them to the scanning channel 11. The first paper feed module 15 is used to drive the documents to move along the scanning channel 11. After passing through the scanning module 14, the documents are transported to the calculation waiting mechanism 2. The scanning module 14 is used to scan the documents that have passed through and transmit the scanned images to the calculation module for processing.
[0029] The paper feeding module 13 includes a paper feed motor 131, a paper separation motor 132, a paper feed roller 133, and a paper separation roller 134. The paper feed roller 133 and the paper separation roller 134 are disposed between the paper feeding table 12 and the scanning channel 11, and there is a gap between the paper feed roller 133 and the paper separation roller 134 for the document to pass through. The paper feed motor 131 is driven to the paper feed roller 133, and the paper separation motor 132 is driven to the paper separation roller 134. The paper feeding table 12 is provided with a paper pickup roller 121 and a lifting motor 122 at the top and bottom, respectively. The lifting motor 122 is driven to the paper feeding table 12 and is used to drive the paper feeding table 12 to move up and down, so that the document at the top of the paper feeding table 12 abuts against the paper pickup roller 121. The paper feed motor 131 is driven to the paper pickup roller 121 and is used to drive the paper pickup roller 121 to rotate, and to drive the document at the top of the paper feeding table 12 into the gap between the paper feed roller 133 and the paper separation roller 134.
[0030] When the document is being reviewed, the lifting motor 122 drives the paper feed table 12 to move upward. The paper feed table 12 is equipped with a lifting top detection sensor and a lifting bottom detection sensor at its top and bottom, respectively. The lifting top detection sensor and the lifting bottom detection sensor can be position sensors used to detect whether the paper feed table 12 has reached the lifting position. The paper feed table 12 is equipped with a paper presence sensor to detect whether there is no paper on the paper feed table 12. After the paper feed table 12 has risen to the position, the paper feed motor 131 drives the paper pickup roller 121 to rotate, and drives the document at the top of the paper feed table 12 into the gap between the paper feed roller 133 and the paper separation roller 134. The paper feed roller 133 and the paper separation roller 134, driven by the paper feed motor 131 and the paper separation motor 132, drive the document into the scanning channel 11.
[0031] The scanning module 14 includes a scanning detection sensor 141 and an image sensor 142 disposed on the scanning channel 11. The scanning detection sensor 141 is located in front of the image sensor 142 and is used to detect whether a document is passing by. The image sensor 142 is used to scan and photograph the passing document. The image sensor 142 is a CIS image sensor and is electrically connected to the computing module, which can transmit the scanned document image to the computing module for processing.
[0032] The first paper feeding module 15 includes a first paper feeding motor 151 and a first paper feeding roller group 152 that is drivenly connected to the first paper feeding motor 151. The first paper feeding roller group 152 is multiple and is evenly distributed along the length direction of the scanning channel 11.
[0033] On the scanning channel 11, between the paper feed module 13 and the scanning module 14, there are also sequentially arranged a skew detection sensor 16, a left and right overwidth detection sensor 17, and an ultrasonic sensor 18. The skew detection sensor 16 and the left and right overwidth detection sensor 17 can be distance sensors, and there are two of each. The skew detection sensor 16 is used to detect whether the orientation of the document is tilted, and the left and right overwidth detection sensor 17 is used to detect whether the document is shifted to the sides. There are also two ultrasonic sensors 18, which are respectively set above and below the scanning channel 11, and are used to detect whether the documents overlap.
[0034] The calculation waiting mechanism 2 includes a calculation waiting channel 21, a second paper feed motor 22, and a second paper feed roller group 23. The two ends of the calculation waiting channel 21 are connected to the output end of the paper feeding scanning mechanism 1 and the input end of the printing mechanism 3, respectively. Multiple second paper feed roller groups 23 are evenly spaced along the calculation waiting channel 21. The second paper feed motor 22 is connected to the second paper feed roller groups 23 for driving their rotation. The document scanned by the paper feeding scanning mechanism 1 is transmitted to the printing mechanism 3 along the calculation waiting channel 21. The time it takes for the document to travel through the entire calculation waiting channel 21 is not less than the time it takes for the calculation module to process the document. This ensures that all documents arriving at the printing mechanism 3 have been processed and can be printed directly.
[0035] Because the scanning speed of the paper feed scanning mechanism 1 is relatively fast, too many documents will be scanned during the processing time of the calculation module. In order to ensure that the documents on the calculation waiting channel 21 do not overlap, the calculation waiting channel 21 must be long enough, which would result in the entire device occupying too much space. Therefore, this invention sets up multiple calculation waiting channels 21. The first paper path diversion control motor 24 can sequentially send the rapidly scanned documents into different calculation waiting channels 21 according to a set program. This can greatly shorten the length of a single calculation waiting channel 21, thereby reducing the overall size of the device. The specific method is as follows: Two calculation waiting channels 21 are set up. The output end of the paper feed scanning mechanism 1 is equipped with a first paper path diversion control motor 24. The first paper path diversion control motor 24 is used to control one of the calculation waiting channels 21 to connect with the output end of the paper feed scanning mechanism 1 (i.e., the exit of the scanning channel 11), so that the documents output by the paper feed scanning mechanism 1 enter the calculation waiting channel 21. The input end of the printing mechanism 3 is equipped with a second paper path diversion control motor 25. Each calculation waiting channel 21 is equipped with a paper arrival detection sensor 26 near the second paper path diversion control motor 25. When the paper arrival detection sensor 26 detects a document passing by, the second paper path diversion control motor 25 controls the operation waiting channel 21 where the paper arrival detection sensor 26 is located to connect with the input end of the printing mechanism 3 (i.e., the entrance of the printing channel 31), so that the document enters the printing mechanism 3; alternatively, the second paper path diversion control motor 25 can be removed, so that multiple operation waiting channels 21 are always connected to the input end of the printing mechanism 3; the operation waiting channel 21 is also equipped with a paper jam detection sensor 27, which can be used to detect whether there is a paper jam in the operation waiting channel 21.
[0036] The printing mechanism 3 includes a printing channel 31, a third paper feed motor 32, a third paper feed roller group 33, and a printing module 34. One end of the printing channel 31 is connected to the calculation and waiting mechanism 2, and the other end is connected to the paper output platform. There are multiple third paper feed roller groups 33, which are evenly spaced along the printing channel 31. The third paper feed motor 32 is connected to the third paper feed roller group 33 for driving the third paper feed roller group 33 to rotate, thereby moving the document along the printing channel 31. The printing module 34 is set on the printing channel 31 and prints the document according to the calculation result of the calculation module.
[0037] Two printing modules 34 are located on either side of the printing channel 31, used for printing both sides of a document, greatly improving printing efficiency. A printing detection sensor is also provided in front of each printing module 34 to detect whether a document has entered the corresponding printing module 34. Each printing module 34 includes a printhead, a printhead movement motor, an ink extraction motor, ink channels, left and right limit detectors, and a printhead anti-collision detector, etc., which are existing technologies and will not be described in detail here. The aforementioned computing module can be integrated into the printing trace retention system of this invention, or it can be an external computer electrically connected to the printing trace retention system of this invention.
[0038] like Figure 3 As shown, the specific process of the trace printing of the present invention is as follows:
[0039] Taking two operation waiting channels as an example, the two operation waiting channels are named operation waiting channel A and operation waiting channel B, respectively. The corresponding paper arrival detection sensors are named paper arrival detection sensor A and paper arrival detection sensor B, respectively. The corresponding second paper feed motors are named paper feed motor B and paper feed motor C, respectively. The first paper feed motor is named paper feed motor A, and there are two third paper feed motors, named paper feed motor D and paper feed motor E, respectively. The two printing modules are named printing module A and printing module B, respectively. The corresponding two printing detection sensors are named printing detection sensor A and printing detection sensor B, respectively.
[0040] After the device is started, all sensors perform self-checks. If there is an abnormality, an error will be reported. If there is no abnormality, the device will proceed to the trace printing process.
[0041] First, a paperless sensor detects whether there is paper on the paper feed table. If there is no paper, the paperless device will report no paper and stop. If there is paper, the lifting motor drives the paper feed table to rise. Once the top sensor detects that the paper feed table has been raised to the correct position, the lifting motor stops driving.
[0042] Then, the paper arrival detection sensor A detects whether there is paper. When the paper arrival detection sensor A detects no paper, the paper feed motor B and the paper path diversion control motor start, and the scanning channel connects with the calculation waiting channel A. When the paper arrival detection sensor A detects that there is paper, the paper arrival detection sensor B detects whether there is paper. If there is paper, it returns to the paper arrival detection sensor A to detect whether there is paper. If there is no paper, the paper feed motor C and the paper path diversion control motor start, and the scanning channel connects with the calculation waiting channel B. After the scanning channel connects with the calculation waiting channel A or the calculation waiting channel B, the paper feed motor, the paper separation motor, and the paper feed motor A start, pick up the document, and transport it to the scanning channel. After skew detection, overwidth detection, double sheet detection, and scanning detection, the image sensor performs image acquisition. After the acquisition is completed, the paper enters the corresponding waiting area (i.e., the calculation waiting channel A or the calculation waiting channel B). When it reaches the paper arrival sensor A or the paper arrival sensor B, the corresponding paper feed motor B or the paper feed motor C stops; at the same time, the next sheet of paper begins to be fed.
[0043] When paper enters the paper waiting area, the calculation module performs AI calculations on the print file. After the calculations are completed, paper feed motors D, E, and B (or C) rotate synchronously to feed the paper. Print detection sensor A is triggered, starting the printing process of printing module A. There is a position detection sensor behind printing module A. When the tail of the paper exits the position detection sensor, the second sheet of paper begins to be fed into the printing channel. At the same time, the paper that has finished printing one side (i.e., the first sheet of paper) will continue to move along the printing channel. When print detection sensor B is triggered, the printing process of printing module B is started. Finally, the paper is fed to the paper output port, and the process ends.
[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
