Description

Technical Field

[0001] This invention relates to the field of mobile shelving technology, specifically to a mobile shelving control system and control method. Background Technology

[0002] Mobile shelving, also known as mobile shelving, originated in Japan. It is a new type of storage equipment suitable for government agencies, enterprises, and institutions in their libraries, archives, and sample rooms, used for storing books, documents, goods, financial documents, and other items. Compared to traditional bookshelves, shelves, and filing cabinets, it offers greater storage capacity, saves space, and is more traditional in design.

[0003] However, in practical applications, readers need to constantly crank the handwheels to separate the mobile shelving units, which is inconvenient and physically demanding. Furthermore, mobile shelving units are generally arranged in a single layer, which wastes space and prevents the installation of more units in the same area, resulting in low space utilization. If the mobile shelving units are arranged in double layers, readers need to use ladders to retrieve them, which is dangerous, time-consuming, and laborious. Overall, the existing mobile shelving technology has many drawbacks and poor practicality. Summary of the Invention

[0004] This invention provides a mobile shelving system and control method, aiming to solve the problems of wasted space and poor practicality of single-layer mobile shelving in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A mobile shelving control system includes a mobile shelving unit, an alarm module, a moving module, a sliding module, an electronic input module, and a control module; the control module is used to control the moving module to move on the sliding module. The mobile shelving unit is used to slide on the sliding module; the control module is also used to drive the mobile shelving unit to slide on the sliding module. The alarm module is installed on the mobile shelving unit and is used to emit a buzzer. The electronic data entry module is used to display the archive information inside the compact shelving unit; The mobile shelving unit consists of several groups, each group slidably mounted on a sliding module. Each mobile shelving unit comprises two shelving units. The top of the lower shelving unit has a mounting plate with a mounting groove. The inner surface of the mounting groove has two mounting holes, each containing a first spring with a first limiting block connected to its end. The bottom of the upper shelving unit has a mounting pin with two second limiting blocks on its outer surface. Both the first and second limiting blocks have guide slopes. The mounting pin is used to install in the mounting groove, and the second limiting blocks are used to insert into the mounting holes. The lower shelving unit slides on the sliding module.

[0006] Furthermore, a sliding plate is provided at the bottom of the mobile shelving unit located below. Limiting parts are provided at both ends of the sliding plate, and several pulleys are provided at the bottom of the limiting parts. The pulleys are used to slide on the sliding module.

[0007] Furthermore, the sliding module includes a drive assembly and a sliding assembly. The sliding assembly includes two support plates, with a detachable limit plate on each support plate. After the limit plate is connected to the support plate, a first sliding surface and a second sliding surface are formed. The slide plate is slidably mounted on the first sliding surface. Limit grooves are provided on both the first and second sliding surfaces, and a track is provided in the limit groove. The limiting part is used to slide in the limit groove, and the roller is used to slide in the track. Slide rails are also provided on both sides of the support plate. The moving module is slidably mounted on the slide rails and slides in the second sliding surface. The drive assembly is used to drive the mobile shelving unit below to slide on the first sliding surface.

[0008] Furthermore, the drive assembly includes a first motor, a first ball screw connected to the output shaft of the first motor, a first mounting block disposed below the slide plate, a first screw nut disposed inside the first mounting block, a plurality of positioning holes disposed on the outer surface of the first screw nut, a second spring disposed inside the positioning holes, a permanent magnet disposed at the end of the second spring, an electromagnet disposed inside the first mounting block, the magnetic poles of the electromagnet being the same as the magnetic poles of the permanent magnet, the initial state of the electromagnet being the open state, both the electromagnet and the first motor being connected to a control module, the control module being used to control the start and stop of the first motor and the switching of the electromagnet.

[0009] Furthermore, the moving module includes two moving components, which are slidably mounted on two slide rails respectively; The moving component includes a support platform, a slide table, and a second motor. A slide groove and an extended sliding plate are provided below the slide table. The slide groove slides in cooperation with the slide rail. The extended sliding plate is slidably disposed on the second sliding surface. Several hydraulic cylinders are provided above the slide table. The support platform is mounted on the movable end of several hydraulic cylinders. A moving groove is provided on the support platform. A moving plate is provided inside the moving groove. A second lead screw nut is provided inside the moving plate. A support plate is provided on the support platform. The second motor is disposed on the support plate. A second ball screw is provided on the output shaft of the second motor. The second ball screw is used to cooperate with the second lead screw nut. A second mounting block is provided at the bottom of the slide table, and a third lead screw nut is fixedly installed inside the second mounting block. A third ball screw is fitted on the third lead screw nut, and a third motor is connected to the end of the third ball screw.

[0010] Furthermore, guardrails are installed on the support platform.

[0011] Furthermore, connecting plates are provided at the ends of the slide rail and the support plate, and the first ball screw and the third ball screw are rotatably engaged with the connecting plates.

[0012] Furthermore, the alarm module includes an alarm light and a distance sensor. Each of the lower mobile shelving units is equipped with a distance sensor, the alarm light is mounted on a mounting plate, and the distance sensor is connected to the alarm light via a controller.

[0013] Furthermore, the electronic data entry module includes a host and a display screen. The host and the display screen are connected. The host is used to enter all the files inside the mobile shelving unit, and the display screen is used to display the location of the files inside the mobile shelving unit and retrieve information. The control module is used to control the switching of the first motor, the second motor, and the third motor.

[0014] A method for controlling mobile shelving units includes the following steps: When only one person is accessing the file: S1: Users view the location of the files they need to view on the display screen; S2: After locating the file, the user records and files the file to be retrieved through the main unit; S3: The reader stands on the moving plate and operates the control module to close the electromagnets inside the first mounting holes at the bottom of all the mobile shelves in front of the mobile shelf where the file to be searched is located. After the electromagnets are opened, since the permanent magnets are no longer repelled by the like poles of the electromagnets, the permanent magnets and springs extend, causing the lead screw nut and the first mounting hole to form an integrated structure. S4: The reader controls the first motor to start through the control module. After the first motor starts, all the mobile shelves in front of the mobile shelf where the file to be searched is located move away from the mobile shelf where the file to be searched is located. Since the electromagnets inside the first mounting block at the bottom of the mobile shelf where the file to be searched is located and the mobile shelf behind the mobile shelf where the file to be searched is located are initially in the open state, the electromagnets compress the permanent magnet and the spring, causing the lead screw nut to rotate and engage with the first mounting block. Therefore, after the first motor rotates, the mobile shelf where the file to be searched is located and the mobile shelf behind the mobile shelf where the file to be searched is located will not move, so the mobile shelf where the file to be searched is located will be exposed. S5: The reader controls the third motor to rotate, and after the third motor rotates, it drives the slide to the location of the compact shelf where the file to be searched is located; S6: The reader controls the second motor to rotate, and the moving plate moves towards the mobile shelving. When the moving plate is between two mobile shelving units, the second motor stops rotating. After the reader retrieves the file, the slide and mobile shelving unit are reset. S601: When the file to be retrieved is inside the upper mobile shelving unit, in step S6, after the moving plate is positioned between the two mobile shelving units, the reader controls the second motor to stop rotating and controls the telescopic device to extend. At this time, the support platform is raised as a whole. After the support platform is raised, the reader can retrieve the file inside the upper mobile shelving unit. Finally, the support platform, sliding table, and mobile shelving unit are reset to complete the retrieval of the file.

[0015] When only two people are simultaneously accessing and reviewing the files: S7: After completing steps S1 and S2, another reader executes steps S3 and S4, exposing the mobile shelving unit containing the file to be searched. During this process, the distance between two adjacent mobile shelving units will decrease when the first reader retrieves the file. To facilitate simultaneous file browsing by both readers, a distance sensor monitors the distance between two adjacent mobile shelving units in real time. When the distance between two adjacent mobile shelving units reaches a threshold, the distance sensor transmits a signal to the controller. The controller then controls the alarm light to sound a buzzer to remind the reader operating the first motor to stop controlling the first motor, thus preventing interference between the two readers when retrieving and browsing the file.

[0016] When only two or more people are simultaneously accessing and reviewing the files: S8: After completing steps S1 and S2, other users stand in line on the mobile board and wait for the previous user to complete the file retrieval before proceeding with steps S3-S6 to retrieve the file.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention mainly includes a mobile shelving unit, an alarm module, a moving module, a sliding module, an electronic input module, and a control module. The control module controls the movement of the moving module on the sliding module. In actual use, two mobile shelving units need to be installed together to form a mobile shelving unit. During installation, the mounting pin at the bottom of the upper mobile shelving unit is inserted into the mounting groove at the top of the lower mobile shelving unit. When the mounting pin enters the mounting groove, the second limiting blocks at both ends of the mounting pin, due to the guide slope, push the first limiting block into the mounting hole. At this time, the mounting pin and the mounting hole cooperate, thereby allowing the upper mobile shelving unit to move. Fixed to the top of the lower mobile shelving unit, the double-layered design allows for more mobile shelving units to be placed in the same space, improving space utilization. During use, the alarm module primarily prevents multiple users from accessing multiple mobile shelving units simultaneously, controlling the distance between each user when retrieving files and avoiding interference. Users can access and register the files they wish to retrieve via an electronic entry module. They can then stand on a movable module, which guides them to the desired mobile shelving unit for file retrieval. This approach ensures efficient space utilization without disrupting file retrieval.

Detailed Implementation

[0026] The present invention will be further described below with reference to embodiments. These embodiments are merely some, not all, of the embodiments of the present invention. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the protection scope of the present invention.

[0027] Example 1 Please see Figures 1-6 As shown, this embodiment discloses a mobile shelving control system, including a mobile shelving unit 101, an alarm module, a moving module, a sliding module, an electronic input module, and a control module; the control module is used to control the moving module to move on the sliding module; The mobile shelving unit 101 is slidably mounted on the sliding module; the control module is also used to drive the mobile shelving unit 101 to slide on the sliding module. The alarm module is installed on the mobile shelving unit 101 and is used to emit a buzzer. The electronic data entry module is used to display the file information inside the compact shelving unit 101; There are several mobile shelving units 101, each slidably mounted on a sliding module. Each mobile shelving unit 101 consists of two mobile shelving units. The top of the lower mobile shelving unit is provided with a mounting plate 102, which has a mounting groove 103. The inner surface of the mounting groove 103 has two mounting holes 104, and a first spring 105 is installed in each mounting hole 104. The end of the first spring 105 is connected to a first limiting block 106. The bottom of the upper mobile shelving unit is provided with a mounting pin 107, which has two second limiting blocks 108 on its outer surface. Both the first limiting block 106 and the second limiting block 108 have guide slopes 109. The mounting pin 107 is used to install in the mounting groove 103, and the second limiting blocks 108 are used to insert into the mounting holes 104. The lower mobile shelving unit is used to slide on the sliding module. This invention mainly includes a mobile shelving unit 101, an alarm module, a moving module, a sliding module, an electronic input module, and a control module. The control module controls the moving module to move on the sliding module. In actual use, two mobile shelving units need to be installed together to form a mobile shelving unit 101. During installation, the mounting pin 107 at the bottom of the upper mobile shelving unit is inserted into the mounting groove 103 at the top of the lower mobile shelving unit. When the mounting pin 107 enters the mounting groove 103, the second limiting blocks 108 at both ends of the mounting pin 107, due to the action of the guide slope 109, push the first limiting block 106 into the mounting hole 104. At this time, the mounting pin 107... 7 mates with mounting hole 104, thus fixing the upper mobile shelving unit to the top of the lower mobile shelving unit. By setting up a double-layer mobile shelving unit, more mobile shelving units can be placed in the same space, improving space utilization. In use, the alarm module mainly prevents multiple people from accessing multiple mobile shelving units at the same time, controlling the distance between each reader when retrieving files, and avoiding affecting the reader's file retrieval. Readers can view and register the files to be retrieved through the electronic entry module. Then, the reader can stand on the moving module, which can lead the reader to the mobile shelving unit where the file needs to be retrieved. This ensures space utilization without affecting the file retrieval process.

[0028] In some embodiments, a sliding plate 110 is provided at the bottom of the mobile shelving unit located below. Limiting portions 111 are provided at both ends of the sliding plate 110. A plurality of pulleys 112 are provided at the bottom of the limiting portions 111, and the pulleys 112 are used to slide on the sliding module.

[0029] In some embodiments, the sliding module includes a driving component and a sliding component. The sliding component includes two support plates 113. A limiting plate 114 is detachably provided on the support plate 113. After the limiting plate 114 is connected to the support plate 113, a first sliding surface 115 and a second sliding surface 116 are formed. A slide plate 110 is slidably mounted on the first sliding surface 115. A limiting groove 117 is provided on both the first sliding surface 115 and the second sliding surface 116. A track 118 is provided in the limiting groove 117. A limiting part 111 is used to slide in the limiting groove 117. A roller is used to slide in the track 118. Slide rails 119 are also provided on both sides of the support plate 113. A moving module is slidably mounted on the slide rail 119. The moving module slides in cooperation with the second sliding surface 116. The driving component is used to drive the mobile shelving unit below to slide on the first sliding surface 115.

[0030] In some embodiments, the drive assembly includes a first motor 120, a first ball screw 121 connected to the output shaft of the first motor 120, a first mounting block 122 disposed below the slide plate 110, a first screw nut 123 disposed inside the first mounting block 122, a plurality of positioning holes 124 disposed on the outer surface of the first screw nut 123, a second spring 125 disposed inside the positioning holes 124, a permanent magnet 126 connected to the end of the second spring 125, an electromagnet 127 disposed inside the first mounting block 122, the magnetic poles of the electromagnet 127 being the same as the magnetic poles of the permanent magnet 126, the initial state of the electromagnet 127 being the open state, the electromagnet 127 and the first motor 120 being both connected to a control module, the control module being used to control the start and stop of the first motor 120 and the switching on and off of the electromagnet 127.

[0031] In actual use, the reader stands on the movable platform 134 and operates the control module to close the electromagnets 127 inside the first mounting blocks 122 at the bottom of all the mobile shelves in front of the mobile shelf containing the file to be searched. When the electromagnets 127 are opened, the permanent magnets 126 are no longer repelled by the like poles of the electromagnets 127. The permanent magnets 126 and the springs extend, causing the lead screw nut and the first mounting block 122 to form an integrated structure. At this time, the reader controls the first motor 120 to start through the control module. After the first motor 120 starts, all the mobile shelves in front of the mobile shelf containing the file to be searched move away from the mobile shelf containing the file to be searched. The electromagnet 127 inside the first mounting block 122 at the bottom of the mobile shelving unit containing the file to be searched, as well as the mobile shelving unit behind the mobile shelving unit containing the file to be searched, is initially in the open state. Therefore, the electromagnet 127 compresses the permanent magnet 126 and the spring, causing the lead screw nut to rotate in conjunction with the first mounting block 122. Thus, after the first motor 120 rotates, the mobile shelving unit containing the file to be searched, as well as the mobile shelving unit behind the mobile shelving unit containing the file to be searched, will not move, and the mobile shelving unit containing the file to be searched will be exposed. The advantage of this setting is that the mobile shelving units in different positions can be moved individually by one motor and one ball screw, effectively saving costs.

[0032] In some embodiments, the moving module includes two moving components, which are slidably disposed on two slide rails 119 respectively. The movable assembly includes a support platform 128, a slide table 129, and a second motor 130. A slide groove and an extended sliding plate 131 are provided below the slide table 129. The slide groove slides in cooperation with a slide rail 119. The extended sliding plate 131 is slidably mounted on a second sliding surface 116. Several hydraulic cylinders 132 are provided above the slide table 129. The support platform 128 is mounted on the movable ends of the hydraulic cylinders 132. A moving groove 133 is provided on the support platform 128. A moving plate 134 is provided inside the moving groove 133. A second lead screw nut 135 is provided inside the moving plate 134. A support plate 136 is provided on the support platform 128. The second motor 130 is mounted on the support plate 136. A second ball screw 137 is provided on the output shaft of the second motor 130. The second ball screw 137 is used to cooperate with the second lead screw nut 135. A second mounting block 138 is provided at the bottom of the slide table 129. A third lead screw nut 139 is fixedly installed inside the second mounting block 138. A third ball screw 140 is fitted on the third lead screw nut 139. A third motor 141 is connected to the end of the third ball screw 140.

[0033] In actual use, the reader controls the second motor 130 to rotate, and the moving plate 134 moves towards the mobile shelving. When the moving plate 134 is positioned between the two mobile shelving units, the second motor 130 stops rotating. After the reader retrieves the file, the slide table 129 and the mobile shelving unit are reset.

[0034] The advantage of this setup is that readers do not need to walk around to retrieve files. They can stand on the movable board 134, which can guide them to the front of the mobile shelving unit.

[0035] In some embodiments, a guardrail 142 is provided on the support platform 128. The purpose of the guardrail 142 is to facilitate the reader to lean on it and to prevent the reader from falling off the moving plate 134 due to the inertia generated when the moving plate 134 moves.

[0036] In some embodiments, the ends of the slide rail 119 and the support plate 113 are provided with connecting plates 143, and the first ball screw 121 and the third ball screw 140 are rotatably engaged with the connecting plates 143.

[0037] In actual use, the function of the connecting plate 143 is to make the first ball screw 121 and the third ball screw 140 more stable when rotating.

[0038] In some embodiments, the alarm module includes an alarm light 146 and a distance sensor 147. Each of the lower mobile shelving units is equipped with the distance sensor 147. The alarm light 146 is mounted on the mounting plate 102. The distance sensor 147 is connected to the alarm light 146 via a controller.

[0039] In actual use, when only two or more readers retrieve and consult files at the same time, the distance between two adjacent mobile shelves will decrease when the first reader retrieves a file. In order to facilitate two readers to browse the files at the same time, the distance sensor 147 monitors the distance between two adjacent mobile shelves in real time. When the distance between two adjacent mobile shelves reaches the threshold, the distance sensor 147 transmits a signal to the controller, and the controller controls the alarm light 146 to sound a buzzer to remind the reader who is operating the first motor 120 to stop controlling the first motor 120, so as to avoid interference between two readers when retrieving and browsing files.

[0040] It should be noted that the threshold of distance sensor 147 refers to the minimum distance between two mobile shelving units when a reader retrieves files.

[0041] In some embodiments, the electronic input module includes a host 144 and a display screen 145. The host 144 is connected to the display screen 145. The host 144 is used to input all the files inside the mobile shelving unit, and the display screen 145 is used to display the location of the files inside the mobile shelving unit and retrieval information. The control module is used to control the switching of the first motor 120, the second motor 130 and the third motor 141.

[0042] In actual use, every file placed inside the mobile shelving unit needs to be registered on the host 144, which records the file information and its location. The display screen 145 can display the location of each file in real time. When a reader retrieves a file, the file also needs to be registered on the host 144. After use, the file is returned to its original position. The advantage of this setup is that staff do not need to search for the file location themselves; they can retrieve the file directly through the file information displayed on the display screen 145.

[0043] Example 2 Please see Figures 1-6 As shown in the figure, this embodiment discloses a control method for mobile shelving units, including the following steps: When only one person is accessing the file: S1: The reader can view the location of the file they need to view through the display screen 145; S2: After locating the file, the user records and files the file to be retrieved through host 144; S3: When the reader stands on the movable plate 134, the operation control module controls the electromagnets 127 inside the first mounting block 122 at the bottom of all the mobile shelves in front of the mobile shelf where the file to be searched is located to close. After the electromagnets 127 are opened, since the permanent magnets 126 are no longer repelled by the like poles of the electromagnets 127, the permanent magnets 126 and the springs are extended, so that the screw nut and the first mounting block 122 form an integrated structure. S4: The reader controls the first motor 120 to start via the control module. After the first motor 120 starts, all the mobile shelves in front of the mobile shelf where the file to be searched is located move away from the mobile shelf where the file to be searched is located. Since the electromagnet 127 inside the first mounting block 122 at the bottom of the mobile shelf where the file to be searched is located and the mobile shelf behind the mobile shelf where the file to be searched is located are initially in the open state, the electromagnet 127 compresses the permanent magnet 126 and the spring, causing the lead screw nut to rotate and engage with the first mounting block 122. Therefore, after the first motor 120 rotates, the mobile shelf where the file to be searched is located and the mobile shelf behind the mobile shelf where the file to be searched is located will not move, so the mobile shelf where the file to be searched is located will be exposed. S5: The reader controls the third motor 141 to rotate. After the third motor 141 rotates, it drives the slide table 129 to slide to the location of the mobile shelving where the file to be searched is located. S6: The reader controls the second motor 130 to rotate, and the moving plate 134 moves towards the mobile shelving. When the moving plate 134 is between the two mobile shelving units, the second motor 130 stops rotating. After the reader retrieves the file, the slide table 129 and the mobile shelving unit are reset. S601: When the file to be retrieved is inside the mobile shelving unit located above, in step S6, after the position of the moving plate 134 is between the two mobile shelving units, the reader controls the second motor 130 to stop rotating and controls the telescopic device to extend. At this time, the support platform 128 is raised as a whole. After the support platform 128 is raised, the reader can take the file inside the mobile shelving unit located above. Finally, the support platform 128, the sliding table 129 and the mobile shelving unit are reset to complete the retrieval of the file.

[0044] When only two people are simultaneously accessing and reviewing the files: S7: After completing steps S1 and S2, another reader executes steps S3 and S4, exposing the mobile shelving unit containing the file to be searched. During this process, the distance between two adjacent mobile shelving units will decrease when the first reader retrieves the file. To facilitate simultaneous file retrieval by both readers, distance sensor 147 monitors the distance between two adjacent mobile shelving units in real time. When the distance between two adjacent mobile shelving units reaches a threshold, distance sensor 147 transmits a signal to the controller. The controller then controls alarm light 146 to sound a buzzer to remind the reader operating the first motor 120 to stop controlling the first motor 120, thus preventing interference between the two readers when retrieving and browsing the file.

[0045] When only two or more people are simultaneously accessing and reviewing the files: S8: After completing steps S1 and S2, other readers stand on the mobile board 134 and wait in line until the previous reader has completed the file retrieval before proceeding with steps S3-S6 to retrieve the file.

[0046] Example 3 like Figures 1-4As shown, this embodiment further defines embodiment one. In this embodiment, the lower shelves of the mobile shelving are numbered A, B, C, D, E, F... from left to right, and the upper shelves are numbered a, b, c, d, e, f... from left to right. When the file that the reader needs to retrieve is in shelf c, the staff records the file to be retrieved through the host 144. Then, standing on the moving plate 134, the operation control module controls the electromagnets 127 inside the first mounting block 122 at the bottom of shelves A and B to close. After the electromagnets 127 are opened, since the permanent magnets 126 are no longer repelled by the like poles of the electromagnets 127, the permanent magnets 126 and the springs extend, causing the screw nut and the first mounting block 122 to form an integrated structure. Then, the first motor 120 is started, and the electromagnets 127 in shelves C, D, E, and F... The compression of the permanent magnet 126 and the spring causes the lead screw nut to rotate in conjunction with the first mounting block 122. Therefore, after the first motor 120 rotates, the C, D, E, and F mobile shelves will not move, while the A and B mobile shelves will move away from the C mobile shelf, thus exposing the C mobile shelf. At the same time, the reader controls the second motor 130 to rotate, and the moving plate 134 moves towards the mobile shelf. When the moving plate 134 is positioned between two mobile shelves, the second motor 130 stops rotating. Then, the reader controls the second motor 130 to stop rotating and controls the telescopic device to extend. At this time, the support platform 128 is raised as a whole.

9. A control method for a mobile shelving control system as described in claim 8, characterized in that: Includes the following steps: When only one person is accessing the file: S1: The reader views the location of the file to be viewed on the display screen (145); S2: After finding the location of the file, the reader records and files the file to be retrieved through the host (144); S3: The reader stands on the movable plate (134) and operates the control module to control the electromagnets (127) inside the first mounting holes (104) at the bottom of all the mobile shelves in front of the mobile shelf where the file to be searched is located to close. After the electromagnets (127) are opened, since the permanent magnets (126) are no longer repelled by the like poles of the electromagnets (127), the permanent magnets (126) and the springs are extended, so that the screw nut and the first mounting hole (104) form an integral structure. S4: The reader controls the first motor (120) to start through the control module. After the first motor (120) starts, all the mobile shelves in front of the mobile shelf where the file to be searched is located move away from the mobile shelf where the file to be searched is located. Since the electromagnet (127) inside the first mounting block (122) at the bottom of the mobile shelf where the file to be searched is located and the mobile shelf behind the mobile shelf where the file to be searched is located is initially in the open state, the electromagnet (127) compresses the permanent magnet (126) and the spring, so that the screw nut and the first mounting block (122) rotate and cooperate. Therefore, after the first motor (120) rotates, the mobile shelf where the file to be searched is located and the mobile shelf behind the mobile shelf where the file to be searched is located will not move, so the mobile shelf where the file to be searched is located will be exposed. S5: The reader controls the third motor (141) to rotate. After the third motor (141) rotates, it drives the slide (129) to slide to the location of the compact shelf where the file to be searched is located. S6: The reader controls the second motor (130) to rotate, and the moving plate (134) moves towards the mobile shelving. When the moving plate (134) is positioned between the two mobile shelving units, the second motor (130) stops rotating. After the reader retrieves the file, the slide (129) and the mobile shelving unit are reset. S601: When the file to be retrieved is inside the mobile shelving unit located above, in step S6, after the position of the moving plate (134) is between the two mobile shelving units, the reader controls the second motor (130) to stop rotating and controls the telescopic device to extend. At this time, the support platform (128) is raised as a whole. After the support platform (128) is raised, the reader can take the file inside the mobile shelving unit located above. Finally, the support platform (128), the sliding table (129) and the mobile shelving unit are reset to complete the retrieval of the file. When only two people are simultaneously accessing and reviewing the files: S7: After completing steps S1 and S2, another reader executes steps S3 and S4, which exposes the mobile shelving where the file to be searched is located. During this process, when the first reader retrieves the file, the distance between two adjacent mobile shelving units will decrease. In order to facilitate two readers to browse the file at the same time, the distance sensor (147) monitors the distance between two adjacent mobile shelving units in real time. When the distance between two adjacent mobile shelving units reaches the threshold, the distance sensor (147) transmits a signal to the controller. The controller controls the alarm light (146) to sound a buzzer to remind the reader who is operating the first motor (120) to stop controlling the first motor (120) to avoid interference between the two readers when retrieving and browsing the file. When only two or more people are simultaneously accessing and reviewing the files: S8: After completing steps S1 and S2, other readers stand on the mobile board (134) and wait in line until the previous reader has completed the file retrieval before proceeding with steps S3-S6 to retrieve the file.
