Description

Technical Field

[0001] The present invention relates to the technical field of disinfection equipment, and in particular to an automated file disinfection device. Background Art

[0002] With the continuous development of digital technology, file management work is gradually moving towards informatization and intelligence. However, as an important information carrier, paper files still play an irreplaceable role in many fields. Paper files are prone to moisture, pests, bacteria and viruses. If not effectively disinfected, it will not only affect the preservation life of the files, but also pose a threat to the health of personnel who come into contact with the files.

[0003] Traditional file disinfection methods mainly include chemical fumigation disinfection and ultraviolet surface irradiation disinfection. Although chemical fumigation disinfection has a good disinfection effect, it will cause certain harm to the environment and human health, and the operation process is complex and requires professional personnel to operate. Ultraviolet surface irradiation disinfection has the problem of incomplete disinfection and cannot effectively disinfect the paper inside the files.

[0004] In file management work, there are a large number of files. Manual file disinfection and page turning operations are not only inefficient, but also easy to damage the files. Therefore, developing an efficient, safe and intelligent automated file disinfection device has important practical significance, which can meet the needs of modern file management work for file disinfection and improve the quality and efficiency of file management. Summary of the Invention

[0005] Based on the technical problems existing in the prior art, the present invention proposes an automated file disinfection device.

[0006] An automated file disinfection device proposed by the present invention includes a disinfection cabinet. There are two disinfection chambers in the disinfection cabinet. A cabinet door is rotatably connected in front of each disinfection chamber. A plurality of placement racks are arranged inside each disinfection chamber. Ultraviolet lamps fixed on the inner wall of the disinfection chamber are respectively arranged on both sides of each placement rack. Page turning mechanisms are also respectively arranged on both sides of the placement rack. Stack a pile of files neatly into the corresponding placement rack, then close the cabinet door and turn on the machine. The ultraviolet lamps will disinfect the files. During the disinfection process, the page turning mechanism will turn the pages of this pile of files, so that ultraviolet light can irradiate the internal paper, thereby effectively improving the disinfection quality of the files.

[0007] Preferably, the placement rack includes a set of rotationally symmetric placement plates distributed vertically. The placement plates can move horizontally. One end of each of the two placement plates facing away from each other is provided with a set of inclined plates. The inner surfaces of the two placement plates are respectively fixed with racks, and a gear is meshingly connected between the two racks. The gear is fixedly connected to the output shaft of the first motor, and the first motor is fixed on the rear inner wall of the disinfection chamber. When a stack of files is placed between the two placement plates, during the disinfection process, the first motor drives the gear to rotate, and then the gear meshes to drive the two racks, causing the two placement plates to approach each other. Then, the two sets of inclined plates are used to organize the files into a parallelogram, so that the page-turning mechanism can turn the pages of the paper.

[0008] Preferably, a pair of guide sleeves are provided on the outer surface of the placement plate, and guide rods are inserted into the guide sleeves. The ends of the guide rods are fixed on the inner side wall of the disinfection chamber. The horizontal limit movement of the placement plate can be achieved through the cooperation of the guide sleeves and the guide rods.

[0009] Preferably, a positioning strip is provided on the inner surface of the placement plate in front of the rack. In this way, when placing the files, the edges of the files can be closely attached to the positioning strip, thereby forming a positioning effect on the files and preventing the files from skewing.

[0010] Preferably, the page-turning mechanism includes a second motor and a page-turning plate. The page-turning plate is fixedly connected to the output shaft of the second motor. The page-turning plate has an arc-shaped edge that can contact the side of the paper. The second motor can move synchronously with the corresponding placement plate. When the files are organized into a parallelogram, the inclined surface of the files is exactly tangent to the arc-shaped edge of the page-turning plate. Then, the output shaft of the second motor drives the page-turning plate to rotate, and the page-turning plate can turn the stacked paper through the arc-shaped edge.

[0011] Preferably, the second motor is fixedly connected to a suspension rod. The top of the suspension rod is fixedly connected with a slider. Above each placement rack, a slide rail fixed in the disinfection chamber is provided. Both sliders are slidably connected to the slide rail. A fixed frame is fixedly connected to the suspension rod, and the other end of the fixed frame is fixedly connected to the corresponding placement plate. When the placement plate moves, it will pull the suspension rod through the fixed frame, and the suspension rod will slide in the slide rail through the slider, so that the second motor can move synchronously with the placement plate, and in this way, the page-turning plate can contact the inclined surface of the paper.

[0012] Preferably, a stacking height acquisition module is installed on the inner surface of the lower placement plate of the placement rack, a page-turning resistance acquisition module is installed on the output shaft of the second motor, and a control module is installed on the back of the disinfection cabinet.

[0013] Preferably, the page turning resistance acquisition module is used to detect the page turning resistance moment R in real time, the stacking height acquisition module is used to detect the total stacking height H of the documents, the control module receives the data collected by the page turning resistance acquisition module and the stacking height acquisition module in real time, conducts comprehensive analysis, and then generates an evaluation coefficient. By comparing the evaluation coefficient with a preset reference threshold of the evaluation coefficient, it is determined whether the page turning speed is within a reasonable range, and the working state of the page turning mechanism is controlled according to the comparison result. If the page turning speed is not within a reasonable range, the page turning mechanism will adjust the page turning speed, so as to achieve the best disinfection effect according to the thickness of the paper.

[0014] Preferably, the calculation formula of the evaluation coefficient is as follows:

[0015]

[0016] In the formula, H min : the minimum effective disinfection thickness, R max : the maximum resistance moment allowed by the system, α, β: weight coefficients.

[0017] Preferably, the hierarchical control logic of the control module for the page turning mechanism is as follows:

[0018] Normal mode (K < 0.5):

[0019] Control formula:

[0020] In the formula, t 工作 : the single working time of the motor, v0: the reference speed;

[0021] Enhanced mode (0.5 ≤ K ≤ 0.8):

[0022] Control formula: v 调节 = v0·[1 + 0.5(K - 0.5)]

[0023] In the formula, v 调节 : the dynamically adjusted speed;

[0024] Safety mode (K > 0.8):

[0025] Control formula: F 退避 = μ·R max ·e -t / τ

[0026] In the formula, μ: safety factor, τ: retraction time constant.

[0027] Compared with the prior art, the present invention provides an automated archival disinfection device, which has the following beneficial effects:

[0028] 1. An automated file disinfection device introduces a page-turning mechanism during the disinfection process. By performing page-turning operations on the files, it ensures that ultraviolet light can fully irradiate the papers inside the files. Compared with traditional disinfection methods, it effectively solves the problem that it is difficult to fully disinfect the inside of the files, greatly improves the disinfection quality, and provides a strong guarantee for the long-term safe preservation of the files.

[0029] 2. An automated file disinfection device has a unique design of the placement rack, including a horizontally movable placement plate, an inclined plate, and the cooperation of a rack and a gear, which can organize the files into a parallelogram during the disinfection process to facilitate the page-turning operation of the page-turning mechanism. At the same time, the positioning strips on the inner surface of the placement plate can accurately position the files when they are placed, preventing the files from skewing and ensuring the smooth progress of the disinfection and page-turning processes.

[0030] 3. An automated file disinfection device is equipped with a stacking height acquisition module and a page-turning resistance acquisition module. The control module can receive and analyze these data in real time, judge whether the page-turning speed is reasonable by calculating the evaluation coefficient, and automatically adjust the working state of the page-turning mechanism according to different situations. In addition, for different ranges of evaluation coefficients, the control module also formulates hierarchical control logics such as the normal mode, the enhanced mode, and the safety mode, achieving the intelligent control goal of achieving the best disinfection effect according to the paper thickness and actual situation.

Specific implementation mode

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0040] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0041] Refer to Figures 1-7 , an automated file disinfection device, including a disinfection cabinet 1. There are two disinfection chambers 2 in the disinfection cabinet 1. A cabinet door 3 is rotatably connected in front of each disinfection chamber 2. A plurality of placement racks are arranged inside each disinfection chamber 2. Ultraviolet lamps 4 fixed on the inner walls of the disinfection chambers 2 are respectively arranged on both sides of each placement rack. Page-turning mechanisms are also respectively arranged on both sides of the placement rack;

[0042] During use, a stack of files is neatly placed in the corresponding placement rack, then the cabinet door 3 is closed and the machine is turned on. The ultraviolet lamp 4 will disinfect the files. During the disinfection process, the page-turning mechanism will turn the stack of files, so that the ultraviolet light can irradiate the internal papers, thereby effectively improving the disinfection quality of the files.

[0043] Among them, the placement rack includes a group of rotationally symmetric placement plates 5 distributed up and down. The placement plates 5 can move along the horizontal direction. One group of inclined plates 6 are respectively arranged at the opposite ends of the two placement plates 5. Rack bars 7 are respectively fixed on the inner surfaces of the two placement plates 5. A gear 10 is meshed and connected between the two rack bars 7. The gear 10 is fixedly connected to the output shaft of the first motor 9. The first motor 9 is fixed on the rear inner wall of the disinfection chamber 2;

[0044] During use, stack a pile of files between the two placement plates 5. During the disinfection process, the first motor 9 drives the gear 10 to rotate, and then the gear 10 meshes to drive the two racks 7, causing the two placement plates 5 to approach each other. Then, the files are sorted into a parallelogram through the two sets of inclined plates 6 (as Figure 5 ), so that the page-turning mechanism can turn the pages of the paper.

[0045] Among them, a pair of guide sleeves 20 are provided on the outer surface of the placement plate 5, and guide rods 21 are inserted into the guide sleeves 20. The ends of the guide rods 21 are fixed on the inner side wall of the disinfection chamber 2;

[0046] During use, the placement plate 5 can be limited and moved horizontally through the cooperation of the guide sleeve 20 and the guide rod 21.

[0047] Furthermore, a positioning strip 8 is provided on the inner surface of the placement plate 5 in front of the rack 7;

[0048] During use, when placing the files, the edges of the files can be closely attached to the positioning strip 8, thereby forming a positioning effect on the files and preventing the files from being skewed.

[0049] Among them, the page-turning mechanism includes a second motor 12 and a page-turning plate 13. The page-turning plate 13 is fixedly connected to the output shaft of the second motor 12. The page-turning plate 13 has an arc-shaped edge that can contact the side of the paper. The second motor 12 can move synchronously with the corresponding placement plate 5;

[0050] During use, when the files are sorted into a parallelogram, the inclined surface of the files is exactly tangent to the arc-shaped edge of the page-turning plate 13 (as Figure 5 ), and then the output shaft of the second motor 12 drives the page-turning plate 13 to rotate, and the page-turning plate 13 can turn the stacked paper through the arc-shaped edge.

[0051] Among them, the second motor 12 is fixedly connected to the suspension rod 11. The top end of the suspension rod 11 is fixedly connected with a slider 14. Above each placement rack, a slide rail 15 fixed in the disinfection chamber 2 is provided. The two sliders 14 are both slidably connected to the slide rail 15. A fixed frame 16 is fixedly connected to the suspension rod 11, and the other end of the fixed frame 16 is fixedly connected to the corresponding placement plate 5;

[0052] During use, when the placement plate 5 moves, it will pull the suspension rod 11 through the fixed frame 16, and the suspension rod 11 will slide in the slide rail 15 through the slider 14, so that the second motor 12 can move synchronously with the placement plate 5, and thus the page-turning plate 13 can contact the inclined surface of the paper.

[0053] Furthermore, a stacking height acquisition module 18 is installed on the inner surface of a placement plate 5 located below the placement rack, a page turning resistance acquisition module 17 is installed on the output shaft of the second motor 12, and a control module 19 is installed on the back of the disinfection cabinet 1.

[0054] The page turning resistance acquisition module 17 is used to detect the page turning resistance moment R in real time, and the stacking height acquisition module 18 is used to detect the total height H of the document stack;

[0055] It should be noted that the page turning resistance acquisition module 17 can be an R sensor or other equipment that can detect the page turning resistance torque in real time, the stacking height acquisition module 18 can be an H sensor or other equipment that can detect the total height of the file stack, and the control module 19 is an embedded controller (such as STM32 series) with an integrated data fusion algorithm. Therefore, the page turning resistance acquisition module 17, the stacking height acquisition module 18 and the control module 19 are not specifically limited here and can be selected according to actual needs;

[0056] When in use, the control module 19 receives the data collected by the page turning resistance acquisition module 17 and the stacking height acquisition module 18 in real time, and performs comprehensive analysis, and then generates an evaluation coefficient. By comparing the evaluation coefficient with a pre-set evaluation coefficient reference threshold, it is determined whether the page turning speed is within a reasonable range, and the working state of the page turning mechanism is controlled according to the comparison result. If the page turning speed is not within a reasonable range, the page turning mechanism will adjust the page turning speed so as to achieve the best disinfection effect according to the thickness of the paper.

[0057] In another embodiment, through the cooperation among the page turning resistance acquisition module 17, the stack height acquisition module 18, the control module 19 and the page turning mechanism, the logic of hierarchically controlling the page turning speed is as follows:

[0059] Control formula:

[0060] In the formula, t 工作 : Single working time of the motor (unit: s), v0: reference speed;

[0061] Strengthening mode (0.5≤K≤0.8):

[0063] In the formula, v 调节 : Dynamically adjust the speed;

[0064] Safe mode (K>0.8):

[0065] Control formula: F退避 = μ·R max ·e -t / τ

[0066] Wherein, μ: safety factor, τ: retraction time constant.

[0067] Among them, the calculation formula for the page turning resistance moment is:

[0068] R = k t ·(I 电机 - I 空载 )

[0069] Wherein, k t : motor torque constant (nameplate parameter), I 电机 : real-time working current of the motor, I 空载 : no-load current of the motor (initial calibration value).

[0070] Among them, the calculation formula for the total height of the document stack is:

[0071] H = h 基准 - h 实时

[0072] Wherein, h 基准 : reference distance from the sensor to the shelf surface when no load (preset value), h 实时 : distance from the sensor to the top surface of the document measured in real time.

[0073] Among them, the calculation formula for the evaluation coefficient is:

[0074]

[0075] Wherein, H min : minimum effective disinfection thickness, R max : maximum resistance moment allowed by the system (set according to the rated torque of the motor), α, β: weight coefficients.
