Description

Technical Field

[0001] The invention relates to the technical field of automated assembly, in particular to a multifunctional printing and leaving trace system. Background Art

[0002] In order to reduce the workload of teachers in marking homework and test papers, automatic marking came into being. Automatic marking means that students' homework or test papers are digitized through a scanner, and the digitized homework or test papers are then compared and calculated through a calculation module, and finally the calculation results are printed on the homework or test paper through a printer. This not only reduces the workload of teachers in marking test papers, but also leaves marking traces on the original papers, which is convenient for subsequent teachers' explanations and students' review.

[0003] The existing automatic printing and leaving trace methods mostly involve first scanning the document with a scanner, performing calculations after the scanning is completed, and then putting the document into a printer, which then prints according to the calculation results; the entire printing and leaving trace process is relatively cumbersome, requires manual operation, is time-consuming and labor-intensive, and has low efficiency. In order to improve the efficiency of scanning and printing, people have also designed some printing and leaving trace machines that integrate scanning and printing together, but such printing and leaving trace machines have relatively single functions, cannot perform a separate scanning function, and have a complex structure. When local damage occurs, the maintenance cost is also high. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned prior art and provide a multifunctional printing and leaving trace system which can scan and print as well as scan alone.

[0005] The technical solution of the present invention is to provide a multifunctional printing and leaving trace system with the following structure: It includes a paper feeding scanning mechanism, a first printing mechanism and a second printing mechanism which are arranged in sequence from top to bottom; The paper feed scanning mechanism includes a scanning channel, a paper feed table and a scanning paper output table; the upper and lower ends of the scanning channel are respectively provided with a scanning paper feed port and a first scanning paper output port, and the paper feed table and the scanning paper output table are respectively arranged at the scanning paper feed port and the first scanning paper output port; a scanning transfer channel extending downward is provided at a position close to the first scanning paper output port on the scanning channel, and a first paper path shunt controller is provided at the connection between the scanning channel and the scanning transfer channel, and the first paper path shunt controller is used to control the paper on the scanning channel to be transported to the first scanning paper output port or the scanning transfer channel; The first printing mechanism comprises a printing channel and a printing paper output platform; the upper and lower ends of the printing channel are respectively provided with a printing paper inlet and a printing paper output port, the printing paper inlet of the first printing mechanism is connected with the scanning transfer channel, and the printing paper output platform is arranged at the printing paper output port of the first printing mechanism; a printing transfer channel extending downward is arranged near the printing paper output port on the printing channel, and a second paper path shunt controller is arranged at the connection between the printing transfer channel and the printing channel, and the second paper path shunt controller is used to control the paper on the printing channel to be transported to the printing paper output port or the printing transfer channel; The second printing mechanism has the same structure as the first printing mechanism, and the printing paper inlet of the second printing mechanism is connected to the printing transfer channel of the first printing mechanism.

[0006] After adopting the above structure, the multifunctional printing and leaving trace system in the present invention has the following advantages compared with the prior art: The present invention integrates the paper feeding scanning mechanism, the first printing mechanism and the second printing mechanism together, and can realize automatic scanning, calculation and printing of files without manual operation, thus saving time and labor.

[0007] Since the paper feed scanning mechanism is provided with a first scanning paper outlet, when the user needs to scan the paper separately, he only needs to adjust the scanning channel through the first paper path diversion controller to divert the paper on the scanning channel to the first scanning paper outlet; when the user needs to scan and print, the first paper path diversion controller will divert the paper on the scanning channel to the scanning transfer channel, and then transport it to the first printing mechanism for printing.

[0008] The printing mechanism is configured to be a first printing mechanism and a second printing mechanism of the same structure, which are used to print the front and back sides of the paper respectively, and the printing efficiency is high; and when one of the printing mechanisms is damaged, only the corresponding part needs to be replaced, and the maintenance cost is low.

[0009] Preferably, the paper feed scanning mechanism also includes a paper feed roller group, a scanning module and a first paper feed roller group arranged on the scanning channel; the paper feed roller group is used to pick up the paper on the paper feed table and transport it to the scanning channel, and the first paper feed roller group is used to drive the paper to move along the scanning channel, and after being scanned by the scanning module, it is transported to the first scanning paper outlet or the scanning transfer channel.

[0010] Preferably, an operation waiting mechanism is detachably connected between the paper feed scanning mechanism and the first printing mechanism, and the operation waiting mechanism includes an operation waiting channel and a third paper feed roller group arranged on the operation waiting channel, and the upper and lower ends of the operation waiting channel are respectively connected to the scanning transfer channel and the printing paper feed port, and the third paper feed roller group is used to transfer the paper transmitted by the scanning transfer channel along the operation waiting channel to the printing paper feed port.

[0011] Since the image scanning speed of the paper feed scanning mechanism is relatively fast, while the calculation speed of the operation module is relatively slow, there is a time interval of several seconds. The scanned paper needs to wait for the calculation module to complete the calculation before it can be sent to the printing mechanism for printing, which easily leads to printing failure. In order to avoid the above situation, the present invention sets an operation waiting mechanism between the paper feed scanning mechanism and the first printing mechanism. The time for the paper to pass through the calculation waiting channel can satisfy the completion of the calculation of the operation module, and then the paper is transmitted to the printing mechanism for printing, thereby avoiding the problem of printing failure.

[0012] Preferably, a waiting detection sensor is provided on the operation waiting channel near its lower end exit, and the waiting detection sensor is electrically connected to the paper feed roller group, the first paper feed roller group, and the third paper feed roller group through the control module, and is used to control the start and stop of the paper feed roller group, the first paper feed roller group, and the third paper feed roller group.

[0013] A waiting detection sensor is set on the calculation waiting channel. When the paper passes through the waiting detection sensor, if the calculation module has not completed the calculation, the control module controls the paper feed roller group and the first paper feed roller group to pause, and waits for the calculation module to complete the calculation before transmitting the paper to the printing mechanism for printing, thereby avoiding the problem of printing failure.

[0014] Preferably, a skew detection sensor, a left and right extra-width detection sensor and an ultrasonic sensor are further provided on the scanning channel between the paper feed roller group and the scanning module. The skew detection sensor is used to detect whether the paper is tilted, the left and right extra-width detection sensors are used to detect whether the paper is offset to both sides, and the ultrasonic sensor is used to detect whether the paper overlaps.

[0015] Preferably, the scanning paper output platform can be rotatably connected to the first scanning paper output port to open or close the first scanning paper output port; the scanning paper output platform is provided with a first angle detection sensor for detecting its rotation angle, and the first angle detection sensor is electrically connected to the first paper path diversion controller through the control module; when the scanning paper output platform is rotated to the first scanning paper output port to be opened, the first paper path diversion controller controls the paper on the scanning channel to be transported to the first scanning paper output port; when the scanning paper output platform is rotated to the first scanning paper output port to be closed, the first paper path diversion controller controls the paper on the scanning channel to be transported to the scanning transfer channel. In this way, the user can realize the single scanning function or scanning and printing function of the device by opening or closing the scanning paper output platform, which is convenient for the user to more intuitively judge the current mode of the device.

[0016] Preferably, the first printing mechanism further comprises a second paper feed roller group and a printing module arranged on the printing channel; the second paper feed roller group is used to drive the paper to move along the printing channel, and the printing module prints the passing paper according to the result of the scanning operation.

[0017] Preferably, the printing paper inlet of the printing channel is arranged at the top of the first printing mechanism, and the output end of the printing transfer channel is arranged at the bottom of the first printing mechanism, so as to facilitate the connection between the printing transfer channel of the first printing mechanism and the printing paper inlet of the second printing mechanism.

[0018] Preferably, the print paper output platform can be rotatably connected to the print paper output port to open or close the print paper output port; a second angle detection sensor for detecting its rotation angle is provided on the print paper output platform, and the second angle detection sensor is electrically connected to the second paper path diversion controller through a control module; when the print paper output platform is rotated to the print paper output port to be opened, the second paper path diversion controller controls the paper on the print channel to be transported to the print paper output port; when the print paper output platform is rotated to the print paper output port to be closed, the second paper path diversion controller controls the paper on the print channel to be transported to the print transfer channel.

[0019] Preferably, the output end of the scanning transfer channel is arranged at the bottom of the paper feeding scanning mechanism and corresponds to the position of the paper feeding end of the operation waiting channel, and the paper discharge end of the operation waiting channel is arranged at the bottom thereof and corresponds to the position of the printing paper feeding port of the printing channel. This facilitates the connection of the two ends of the operation waiting channel with the scanning transfer channel and the printing paper feeding port. BRIEF DESCRIPTION OF THE DRAWINGS
