Description

Technical Field

[0001] This utility model relates to a warehousing system, specifically to a mezzanine racking system (RGV). Background Technology

[0002] In warehousing and logistics, mezzanine racks are generally low in height for warehouses or mezzanine spaces with low ceilings. However, if a complete storage function and rapid loading and unloading via shuttles are required in such a low space, a complex structure needs to be designed. This further reduces the space utilization rate in an already low space. In addition, mezzanine racks may store boxes of different sizes, and existing single-size loading platforms cannot accommodate the loading and unloading of boxes of different sizes. Utility Model Content

[0003] Purpose of the utility model: In view of the above-mentioned shortcomings, this utility model provides a mezzanine shelving unit (RGV) with high space utilization and wide applicability.

[0004] Technical solution: To solve the above problems, this utility model adopts a mezzanine rack RGV, including a track arranged horizontally on the rack beam and a lifting module. The lifting module includes two lifting units and a horizontal guide limiting component arranged between the two lifting units. The horizontal guide limiting component is used to limit the lateral distance between the two lifting units. The lifting unit includes an upright perpendicular to the track, a fork mounted on the upright, and a lateral drive device.

[0005] The upright is provided with guide wheels that are supported on the track and move laterally along the track. The lateral drive device is installed on the upright and drives the guide wheels to rotate, thereby driving the upright to move laterally.

[0006] The upright is equipped with a vertical drive device, which drives the forks to move up and down along the upright. The forks of the two lifting units are symmetrically arranged for picking up and placing goods.

[0007] Furthermore, it includes several tracks arranged horizontally on the shelf beams, with the tracks set at different heights of the shelf, and the lifting unit is equipped with guide wheels and a corresponding horizontal drive device for each track.

[0008] Furthermore, the horizontal guide limiting assembly includes several horizontal guide limiting units, which are arranged in parallel at different heights of the upright.

[0009] Furthermore, the horizontal guide limiting unit includes a first connector, a rack fixedly connected to the first connector, a gear meshing with the rack, a second connector mounting the gear, and a clutch mounted on the second connector. The first connector and the second connector are respectively fixedly connected to the uprights of the two lifting units. When the clutch releases the brake, the lateral drive device drives the guide wheel to move and change the distance between the two lifting units. When the clutch engages the brake, the distance between the two lifting units is fixed.

[0010] Furthermore, one end of the rack is fixedly connected to the first connecting member, and the other end of the rack is fixedly provided with mutually parallel limiting slide rails. A slider that moves along the limiting slide rail is provided on the limiting slide rail. The slider is fixedly connected to the second connecting member. The length of the limiting slide rail is shorter than that of the rack, and one end of the limiting slide rail is flush with the rack. Limiting members are provided at both ends of the limiting slide rail. The second connecting member moves between the limiting members at both ends of the limiting slide rail.

[0011] Furthermore, the lateral drive device includes a walking servo motor, a mounting component for mounting the walking servo motor, and a guide wheel fixedly connected to the output end of the walking servo motor. The mounting component is fixedly connected to the upright. An encoder is installed on the walking motor, which is used to determine the relative position between the two lifting units.

[0012] Furthermore, the mounting component includes a third connector, a fixing component, a guide shaft, a guide block, and a spring. The guide wheel and the walking servo motor are mounted on the fixing component. The third connector is fixedly connected to the upright. The third connector and the fixing component are provided with guide holes. Both ends of the guide shaft pass through the guide holes of the third connector and the fixing component, respectively. One end of the guide shaft passes through the guide hole of the fixing component and is limited by the guide block. The spring is sleeved on the outside of the guide shaft and is located between the third connector and the fixing component.

[0013] Furthermore, the guide wheel includes an upper traveling wheel, a lower driven wheel, and a guide wheel. The upper traveling wheel is fixedly connected to the output end of the traveling servo motor and is supported above the track. A guide groove is provided below the track. The lower driven wheel moves along the guide groove, and the guide wheel is located between the side walls of the guide groove and moves along the side walls of the guide groove.

[0014] Furthermore, the up-and-down driving device includes synchronous pulleys located at the upper and lower ends of the upright, a synchronous belt sleeved on the synchronous pulleys, and a synchronous belt motor that drives the synchronous pulleys to rotate. The forks shown are fixedly connected to the synchronous belt. The synchronous belt motor drives the synchronous pulleys to rotate, thereby rotating the synchronous belt and causing the forks to move up and down. The forks are telescopic forks and are equipped with a finger assembly for picking up and placing goods.

[0015] Beneficial effects: Compared with the prior art, the advantages of this utility model are that by moving the forks up and down on the uprights and moving them laterally on the rails, it is possible to store and retrieve goods at different locations on the shelf. By limiting the distance between the two lifting units through the horizontal guide limiting component, the distance between the two forks is also limited. It can adapt to the storage and retrieval of large and small boxes as needed. Attached Figure Description

[0032] like Figure 1 As shown, this embodiment of a mezzanine racking RGV includes several tracks 1 horizontally arranged on the rack beams and a lifting module. The tracks are positioned at different heights on the rack. Each track is equipped with guide wheels and a corresponding horizontal drive device. The number of tracks is arranged according to the equipment height. In this embodiment, two tracks are used as an example. Figures 2 to 4 As shown, the lifting module includes two lifting units 2 and a horizontal guide limiting assembly 3 disposed between the two lifting units 2. The horizontal guide limiting assembly is used to limit the lateral distance between the two lifting units. Each lifting unit 2 includes a vertical pole 21 perpendicular to the track, forks 22 mounted on the vertical pole, and a lateral drive device 23. The vertical pole 21 is provided with guide wheels 24 that are supported on the track 1 and move laterally along the track. The lateral drive device is mounted on the vertical pole 21 and drives the guide wheels 24 to rotate, thereby driving the vertical pole 21 to move laterally. Figure 5 As shown, the forks of the two lifting units are symmetrically arranged for picking up and placing goods.

[0033] The lifting unit is moved by the single-sided lateral drive device 23, which changes the distance between the two lifting units in the lifting module to realize the relative size change of the lifting module. This allows the size of the forks on both sides to be adjusted, enabling the storage of goods in the bins 4 of different widths. After adjusting the fork picking distance, the relative position size between the two lifting units is fixed by the horizontal guide limit component, preventing the relative position size of the fork spacing from changing during equipment operation. The horizontal guide limit component can also connect the two lifting units into a whole, ensuring the stability and rigidity of the overall operation.

[0034] The horizontal guide limiting assembly 3 includes several horizontal guide limiting units, which are arranged in parallel at different heights of the upright. For example... Figure 6 As shown, the horizontal guide limiting unit includes a first connecting member 31, a rack 32 fixedly connected to the first connecting member, a gear 33 meshing with the rack, a second connecting member 34 mounting the gear, and a clutch 35 mounted on the second connecting member. One end of the rack is fixedly connected to the first connecting member, and the other end of the rack is fixedly provided with mutually parallel limiting slide rails 36. A slider 37 that moves along the limiting slide rail is provided on the limiting slide rail. The slider is fixedly connected to the second connecting member. The length of the limiting slide rail is shorter than that of the rack, and one end of the limiting slide rail is flush with the rack. Limiting members are provided at both ends of the limiting slide rail. The second connecting member moves between the limiting members at both ends of the limiting slide rail.

[0035] The first and second connecting parts are fixedly connected to the uprights of the two lifting units, respectively. When the clutch releases the brake, the fork shifts, and the lateral drive device drives the guide wheel to move, changing the distance between the two lifting units. In this embodiment, during the fork shift, one side of the lifting module moves, the gears generate relative displacement, and the slider rail ensures the stable operation of the gear rack. The relative position dimension of the movement is precisely positioned by the encoder (absolute encoder) at the tail of the travel servo motor. When the clutch is engaged, the distance between the two lifting units is fixed.

[0036] like Figure 7 and Figure 8 As shown, the lateral drive device 23 includes a walking servo motor 231, a mounting component 232 for mounting the walking servo motor, and a guide wheel 24 fixedly connected to the output end of the walking servo motor. The mounting component is fixedly connected to the upright. The mounting component 232 includes a third connector 2321, a fixing component 2322, a guide shaft 2323, a guide block 2324, and a spring 2325. The guide wheel 24 and the walking servo motor 231 are mounted on the fixing component 2322. The third connector is fixedly connected to the upright. The third connector and the fixing component are provided with guide holes. Both ends of the guide shaft pass through the guide holes of the third connector and the fixing component, respectively, and one end of the guide shaft passes through the guide hole of the fixing component and is limited by the guide block. The spring is sleeved on the outside of the guide shaft and is located between the third connector and the fixing component. Since the track installation has a certain deviation, a spring is added to the lateral drive device 23 to adjust the wheel center distance between the walking wheels on the two parallel tracks, ensuring that the walking wheels on the tracks are in contact with the tracks and balancing the pressure on the walking wheels of the two tracks.

[0037] The guide wheel 24 includes an upper traveling wheel 241, a lower driven wheel 242, and a guide wheel 243. The upper traveling wheel is fixedly connected to the output end of the traveling servo motor and is supported above the track. A guide groove is provided below the track. The lower driven wheel moves along the guide groove, and the guide wheel is located between the side walls of the guide groove and moves along the side walls of the guide groove.

[0038] The upright 21 is equipped with a vertical drive device, which drives the forks 22 to move up and down along the upright. The forks of the two lifting units are symmetrically arranged for picking up and placing goods. The vertical drive device includes synchronous pulleys at the upper and lower ends of the upright, a synchronous belt sleeved on the synchronous pulleys, and a synchronous belt motor that drives the synchronous pulleys to rotate. The forks are fixedly connected to the synchronous belt. The synchronous belt motor drives the synchronous pulleys to rotate, which in turn drives the synchronous belt to rotate, thereby causing the forks to move up and down.

[0039] like Figures 9 to 14As shown, the fork 22 is a telescopic fork, including an inner fork 221, a middle fork 222, an outer fork 223, a fork motor 224, a timing belt 225, a timing pulley, and several finger assemblies 226. The fork motor 224 is fixed to the inner fork 221. When picking up goods, the fork motor 224 drives the timing pulley to rotate. The timing pulley drives the middle fork 222 to extend outward through the timing belt 225. The timing pulley on the middle fork 222 is equivalent to a fixed pulley, which drives the outer fork 223 to extend outward. According to the depth of the goods, after the forks extend a certain distance, the finger motor in the finger assembly 226 near the shelf drives the finger to rotate, hooking the goods onto the platform. When placing goods, the finger motor in the finger assembly 226 away from the shelf drives the finger to rotate, limiting the goods. Then the middle fork 222 and the outer fork 223 extend to place the goods on the shelf position. Then the middle fork and the outer fork retract.

[0040] The distance between the two forks on the two lifting units of the lifting module is adjusted by the horizontal movement of the upright on the track and the limiting component for horizontal guidance, allowing for the storage and retrieval of large and small bins as needed. Figure 9 The diagram shown illustrates the process of retrieving the large material box. Figure 10 The diagram shown illustrates the process of retrieving the small material box.
