Description

Technical Field

[0001] This utility model relates to the field of mobile shelving technology, and in particular to an intelligent trackless mobile shelving system. Background Technology

[0002] Mobile shelving, also known as mobile cabinets, is a type of high-density filing equipment. It can be defined as a double-sided, fixed-frame rack with casters mounted on its base, allowing it to move linearly along small guide rails laid on the floor. Multiple racks can be brought together or separated as needed. Mobile shelving includes a front panel, cabinet body, and base beams. It is primarily used for storing archives and documents in a centralized manner; when purchasing, the quantity of documents and their intended location should be considered.

[0003] In the existing technology, in order to ensure the smooth movement of the mobile shelving, a sliding rail is installed on the ground and at the rear of the sealed cabinet. However, this installation method creates a large gap between the mobile shelving and the wall, increasing the space occupied on the ground. Secondly, since the bottom of the mobile shelving is usually equipped with rubber wheels, and since rubber wheels are made of flexible material, they will be accelerated to deform and be damaged after long-term pressure.

[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 9 As shown in the figure, the intelligent trackless mobile shelving proposed in this embodiment includes a slide rail 2 and multiple mobile cabinets 1.

[0029] Multiple mobile shelving units 1 are arranged side by side; each mobile shelving unit 1 is equipped with a walking device and a support device at its bottom; the walking device includes multiple rubber wheels 5 mounted at the bottom of the mobile shelving unit 1 and a power component for driving the multiple rubber wheels 5 to rotate synchronously. The power component includes a servo motor 7, a reducer 8, a second drive shaft 42, two first drive shafts 41, two drive gears 61, and two driven gears 62. The second drive shaft 42 and the two first drive shafts 41 are rotatably mounted at the bottom of the mobile shelving unit 1. The multiple rubber wheels 5 are respectively mounted on the two first drive shafts 41. The servo motor 7 and the reducer 8 are both mounted on the mobile shelving unit 1. The output shaft of the servo motor 7 is connected to the input shaft of the reducer 8, and the output shaft of the reducer 8 is connected to the second drive shaft 42. Each drive gear 61 is mounted on the second drive shaft 42, and each driven gear 62 is mounted on the first drive shaft 41 on both sides. The two drive gears 61 are meshed with the two driven gears 62 respectively. The cooperation of the servo motor 7 and the reducer 8 can increase the output torque on the second drive shaft 42. Under the transmission action of the drive gears 61 and the driven gears 62, the first drive shaft 41 can be driven to rotate, thereby driving the multiple rubber wheels 5 to rotate. The support device includes a connecting plate 10, multiple brackets 9 and two linear drive mechanisms 12. The connecting plate 10 is slidably set at the bottom of the mobile shelving 1. The multiple brackets 9 are all connected to the connecting plate 10. The two linear drive mechanisms 12 are respectively installed at both ends of the mobile shelving 1 and their output shafts are all connected to the connecting plate 10.

[0030] The slide rail 2 is located above the mobile shelving unit 1. Multiple wall-mounted brackets 24 are connected to the slide rail 2. T-shaped grooves are opened along the length of the slide rail 2. Multiple mobile shelving units 1 are equipped with mounting shafts 14. Rollers 15 are installed on the mounting shafts 14. Multiple rollers 15 are movably located inside the T-shaped grooves. Limiting plates are provided at both ends of the slide rail 2. The limiting plates movably pass through the upper end of the slide rail 2.

[0031] Multiple mobile shelving units 1 have multiple partitions 3 installed side-by-side on their inner sides. Each partition 3 is equipped with a limiting mechanism, which includes two push plates 17, two limiting rods 23, and a second elastic connecting assembly. The bottom end of each partition 3 has a mounting groove 301. The second elastic connecting assembly includes a first guide rod 25 and a first spring 26. The first guide rod 25 is located inside the mounting groove 301. Both push plates 17 are slidably mounted on the first guide rod 25. The first spring 26 is sleeved on the first guide rod 25. The two limiting rods 23 are respectively connected to the first guide rods 25 on both sides. The movement extends through both ends of the partition 3. Multiple limiting grooves 101 are arranged side by side on both sides of the inner wall of the mobile shelving unit 1. The limiting grooves 101 fit into the ends of the limiting rods 23. When they are pressed inward, the two push plates 17 are pushed inward, causing the two limiting rods 23 to move synchronously. This causes the outer ends of the two limiting rods 23 to move out from the inner side of the corresponding two limiting grooves 101, thereby releasing the limiting work on the partition 3. Through the multiple limiting grooves 101 arranged on both sides of the inner wall of the mobile shelving unit 1, the number of partitions 3 can be increased freely, and the spacing between two adjacent partitions 3 can be adjusted, so that the inner space of the mobile shelving unit 1 can be used rationally.

[0032] Each of the multiple mobile shelving units 1 is equipped with a controller 13, which is electrically connected to the servo motor 7, reducer 8 and linear drive mechanism 12 on the corresponding side.

[0033] The power unit drives multiple rubber wheels 5 to rotate synchronously, thereby driving the mobile shelving unit 1. The rubber wheels 5 can significantly reduce the noise of the mobile shelving unit 1 during movement and have a certain buffering effect. When the servo motor 7 is not working, the controller 13 controls the linear drive mechanism 12 to drive multiple supports 9 to move downward, so that multiple rubber wheels 5 are lifted off the ground, preventing the rubber wheels 5 from deformation and damage caused by long-term pressure, thereby extending the service life of the rubber wheels 5. The slide rail 2 is fixedly installed on the wall by the mounting bracket 24, and the slide rail 2 is located above the mobile shelving unit 1. This structure can reduce the installation gap between the mobile shelving unit 1 and the wall, thereby reducing the floor space occupied by the equipment after installation.

[0034] Example 2

[0035] like Figure 1 , Figure 6 as well as Figure 8As shown in the figure, the intelligent trackless mobile shelving proposed in this embodiment, compared with the first embodiment, in this embodiment, except for the two mobile cabinets 1 on both sides, the other multiple mobile cabinets 1 are open on both sides, and the two mobile cabinets 1 on both sides are open on one side. Except for the leftmost mobile cabinet 1, the left side of the other multiple mobile cabinets 1 are all equipped with sealing strips 30. The setting of sealing strips 30 can improve the sealing between two adjacent mobile cabinets 1, and can activate the functions of dust prevention and moisture prevention.

[0036] The two sides of the mobile shelving unit 1 are respectively connected to a first ventilation pipe 16 and a second ventilation pipe 20. A fan 18 is installed inside the first ventilation pipe 16, and a one-way valve 19 is installed on the first ventilation pipe 16. The one-way valve 19 only allows gas to be discharged through the first ventilation pipe 16. A magnetic ring 22 and a magnetic suction plate 21 are installed inside the second ventilation pipe 20. The magnetic suction plate 21 is rotatably installed on the upper inner side of the magnetic ring 22. A temperature and humidity sensor is installed inside the mobile shelving unit 1. The temperature and humidity sensor can detect the temperature and humidity inside the mobile shelving unit 1. When the air humidity inside the mobile shelving unit 1 exceeds the set range value, the temperature and humidity sensor feeds back the signal to the controller 13, and the controller 13 then controls the fan 18 to start working to accelerate the ventilation inside the mobile shelving unit 1. When the ventilation is started, the magnetic suction plate 21 automatically rotates and opens. When the ventilation is closed, the magnetic suction plate 21 rotates downward and attracts the magnetic ring 22 together.

[0037] Two baffles 11 are arranged side by side at the bottom of the mobile shelving unit 1, and a connecting plate 10 is located between the two baffles 11. The baffles 11 can prevent external air from entering the inside of the mobile shelving unit 1 through the gap at the bottom of the mobile shelving unit 1.

[0038] Example 3

[0039] like Figure 7 As shown in the figure, this embodiment of the intelligent trackless mobile shelving unit, compared with embodiment two, has an anti-pinch mechanism installed on the left side of all the mobile shelving units 1 except for the leftmost one. The anti-pinch mechanism includes an elastic mounting plate 27, a pressure sensor 28, and a first elastic connecting component. The first elastic connecting component includes a second guide rod 291, a second spring 292, and a limiting block 293. The second guide rod 291 movably passes through the baffle 11, and its two ends are connected to the elastic mounting plate 27 and the limiting block 293, respectively. The second spring 292 is sleeved on the second guide rod 291. When the mobile shelving unit 1 is moved, if a person stands between two mobile shelving units 1, the movable mounting plate 27 first contacts the person's leg, causing the movable mounting plate 27 to displace and contact the pressure sensor 28. The pressure sensor 28 then feeds the signal back to the controller, which then controls the servo motor 7 to stop driving, thus achieving the anti-pinch function.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
