Description

Technical Field

[0001] This invention relates to the field of warehousing and logistics technology, and in particular to an automatic sorting device. Background Technology

[0002] An automatic sorting device is a system that uses a trolley that circulates on a track to sort items. Items are input through a feed port, and the device identifies the location where the items need to be sorted after acquiring the item information. The sorting trolley stops at the top of the package, and the package feeding platform transports the items to the sorting trolley. The sorting trolley then automatically transports the items to their destination and unloads them into the containers corresponding to the target compartments. Existing automatic sorting mechanisms are either complex in structure and costly, or simple in structure, relying on the linear movement of a single sorting module for sorting, resulting in low sorting efficiency and large size of the sorting wall, requiring a large footprint. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic distribution device with high distribution efficiency and small size.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] An automatic distribution device includes:

[0006] The frame has several compartments on both sides along its width.

[0007] Two distribution mechanisms are disposed within the frame and spaced apart along the width of the frame. Each distribution mechanism includes a horizontal drive module, a vertical drive module, and a loading platform. The horizontal drive module is disposed within the frame and extends along the length of the frame. The vertical drive module is disposed above the horizontal drive module and is configured to drive the vertical drive module to move horizontally. The loading platform is disposed within the vertical drive module and is configured to drive the loading platform to move vertically. When the two loading platforms are vertically aligned, their projections on the horizontal plane at least partially overlap.

[0008] Several shelves are distributed on both sides of the frame along the width direction. Cargo boxes are provided on the shelves, and each cargo box corresponds to a compartment. The loading platform can unload goods into the corresponding cargo box.

[0009] As a preferred technical solution for the automatic distribution device, the horizontal drive module includes an upper horizontal drive module and a lower horizontal drive module. The upper end of the vertical drive module is slidably connected to the upper horizontal drive module, and the lower end of the vertical drive module is slidably connected to the lower horizontal drive module. The upper horizontal drive module and the lower horizontal drive module are synchronously driven by a linkage drive component.

[0010] As a preferred technical solution for the automatic distribution device, the upper horizontal drive module, the lower horizontal drive module, and the vertical drive module are all synchronous belt drive modules.

[0011] As a preferred technical solution for the automatic distribution device, the upper horizontal drive module and the vertical drive module are connected by a connecting component, which is configured to ensure that the vertical drive module always has a force pressing against the upper horizontal drive module.

[0012] As a preferred technical solution for the automatic distribution device, the connecting assembly includes a first connector, a second connector, a locking member, a mounting shaft, and an elastic member. The first connector is disposed on the upper horizontal drive module, and the second connector is disposed on the vertical drive module. The first connector and the second connector are connected by the locking member, and there is a vertical movement between the first connector and the second connector. The tail end of the mounting shaft passes through the first connector and the second connector in sequence and is limited by a limiting nut. The elastic member is sleeved on the mounting shaft and is disposed in a compressed state between the first connector and the head end of the mounting shaft.

[0013] As a preferred technical solution for the automatic distribution device, the connecting assembly further includes a wear-resistant plate, and the wear-resistant plate is provided between the first connecting member and the second connecting member, as well as between the first connecting member and the head end of the locking member.

[0014] As a preferred technical solution for the automatic distribution device, the loading platform is configured to unload goods into the cargo box on its own side and also to unload goods into the cargo box on the opposite side.

[0015] As a preferred technical solution for the automatic distribution device, the loading platform includes a carriage, a loading platform body, and a moving drive assembly. The carriage is connected to the vertical drive module, the loading platform body is slidably connected to the carriage, and the moving drive assembly is used to drive the loading platform body to move along the width direction of the frame.

[0016] As a preferred technical solution for the automatic distribution device, the upper end of the frame is provided with several indicator lights, each of which corresponds to a cargo box and is used to indicate the status of the corresponding cargo box.

[0017] As a preferred technical solution for the automatic distribution device, it further includes a loading mechanism and a scanning mechanism. The loading mechanism is disposed on one side of the frame along the length direction and is used to receive goods to be distributed. The scanning mechanism is disposed above the loading mechanism and is used to scan the goods on the loading mechanism. The loading mechanism is also used to transfer the scanned goods to the distribution mechanism.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] like Figures 1 to 13 As shown, an embodiment of the present invention provides an automatic distribution device, including a frame 10, a packaging mechanism 20, a barcode scanning mechanism 40, two distribution mechanisms 30, and several shelves 50.

[0046] Reference Figures 1 to 3 The frame 10 has several compartments 11 on both sides along its width. Each compartment 11 is formed by a slide plate 111 and a partition plate 112. Several shelves 50 are distributed on both sides of the frame 10 along its width. Each shelf 50 has a cargo box 60, and each cargo box 60 corresponds to one compartment 11.

[0047] The loading mechanism 20 is located on one side of the frame 10 along its length and is used to receive goods to be distributed. The barcode scanning mechanism 40 is located above the loading mechanism 20 and is used to scan the goods on the loading mechanism 20. The loading mechanism 20 is also used to transfer the scanned goods to the distribution mechanism 30.

[0048] Reference Figures 4 to 6Two distribution mechanisms 30 are both disposed within the frame 10 and spaced apart along the width of the frame 10. Each distribution mechanism 30 includes a horizontal drive module, a vertical drive module 33, and a loading platform 34. The horizontal drive module is disposed within the frame 10 and extends along the length of the frame 10. The vertical drive module 33 is disposed within the horizontal drive module, and the loading platform 34 is disposed within the vertical drive module 33. The horizontal drive module is configured to drive the vertical drive module 33 to move horizontally, and the vertical drive module 33 is configured to drive the loading platform 34 to move vertically, so that the loading platform 34 moves to the corresponding slot 11. When the two loading platforms 34 are vertically aligned, their projections on the horizontal plane at least partially overlap. During movement, the two loading platforms 34 will shift slightly to avoid interference.

[0049] Reference Figure 6 and Figure 7 The horizontal drive module includes an upper horizontal drive module 31 and a lower horizontal drive module 32. The upper end of the vertical drive module 33 is slidably connected to the upper horizontal drive module 31, and the lower end of the vertical drive module 33 is slidably connected to the lower horizontal drive module 32. The upper horizontal drive module 31, the lower horizontal drive module 32, and the vertical drive module 33 are all synchronous belt drive modules.

[0050] Specifically, the upper horizontal drive module 31 includes an upper mold shell, an upper synchronous belt 312, and an upper slide rail. The upper mold shell is located at the upper end of the frame 10, and the length direction of the upper mold shell is consistent with the length direction of the frame 10. An upper driving wheel and an upper driven wheel are respectively provided at both ends of the upper mold shell along the length direction. The upper synchronous belt 312 is wound around the upper driving wheel and the upper driven wheel. The upper slide rail is located on the upper mold shell, and the length direction of the upper slide rail is consistent with the length direction of the upper mold shell. An upper slider 311 is slidably arranged on the upper slide rail, and the upper slider 311 is connected to the upper synchronous belt 312. The upper synchronous belt 312 can drive the upper slider 311 to move along the upper slide rail. The upper end of the vertical drive module 33 is connected to the upper slider 311.

[0051] The lower horizontal drive module 32 includes a lower mold shell, a lower timing belt 322, and a lower slide rail. The lower mold shell is located at the lower end of the frame 10, and the length direction of the lower mold shell is consistent with the length direction of the frame 10. A lower driving wheel and a lower driven wheel are respectively provided at both ends of the lower mold shell along the length direction. The lower timing belt 322 is wound around the lower driving wheel and the lower driven wheel. The lower slide rail is located on the lower mold shell, and the length direction of the lower slide rail is consistent with the length direction of the lower mold shell. A lower slider 321 is slidably arranged on the lower slide rail, and the lower slider 321 is connected to the lower timing belt 322. The lower timing belt 322 can drive the lower slider 321 to move along the lower slide rail. The lower end of the vertical drive module 33 is connected to the lower slider 321.

[0052] Reference Figure 7 and Figure 10The upper horizontal drive module 31 and the lower horizontal drive module 32 are synchronously driven by a linkage drive assembly. The linkage drive assembly includes a linkage motor 351, a linkage drive pulley 352, a linkage driven pulley 353, a linkage transmission belt 354, and a linkage rod 355. The two ends of the linkage rod 355 are connected to the upper drive pulley and the lower drive pulley, respectively. The linkage motor 351 is mounted on the frame 10, the linkage drive pulley 352 is mounted on the output shaft of the linkage motor 351, the linkage driven pulley 353 is mounted on the linkage rod 355, and the linkage transmission belt 354 is wound around the linkage drive pulley 352 and the linkage driven pulley 353. The linkage motor 351 drives the linkage rod to rotate via the linkage drive pulley 352, the linkage transmission belt 354, and the linkage driven pulley 353. The linkage rod simultaneously drives the upper drive pulley and the lower drive pulley to rotate, thereby achieving synchronous drive between the upper synchronous belt 312 and the lower synchronous belt 322.

[0053] Continue to refer to Figure 7 The vertical drive module 33 includes a vertical mold shell, a vertical synchronous belt, and a vertical slide rail. The upper end of the vertical mold shell is connected to the upper slider 311, and the lower end of the vertical mold shell is connected to the lower slider 321. A vertical driving wheel and a vertical driven wheel are respectively provided at the upper and lower ends of the vertical mold shell. The vertical synchronous belt is wound around the vertical driving wheel and the vertical driven wheel. The vertical slide rail is located on the vertical mold shell, and a vertical slider 331 is slidably mounted on the vertical slide rail. The vertical slider 331 is connected to the vertical synchronous belt, which drives the vertical slider 331 to move along the vertical slide rail. The loading platform 34 is connected to the vertical slider 331. The vertical drive module 33 is driven by a vertical motor 332, which is located on the vertical mold shell. The vertical driving wheel is located on the output shaft of the vertical motor 332.

[0054] The upper end of the vertical drive module 33 is connected to the upper slider 311 via a connecting component. The connecting component is configured to ensure that the vertical drive module 33 always has a force that presses against the upper horizontal drive module 31, thereby transmitting the pressure to the upper horizontal drive module 31, reducing the pressure of the vertical drive module 33 on the lower horizontal drive module 32, effectively improving the stability of the overall movement and extending the overall service life.

[0055] Reference Figure 8 and Figure 9The connecting assembly includes a first connecting member 361, a second connecting member 362, a locking member 366, a mounting shaft 363, and an elastic member 365. The first connecting member 361 is connected to the upper slider 311, and the second connecting member 362 is connected to the upper end of the vertical drive module 33. The first connecting member 361 has a first connecting hole 3611, which is a strip-shaped hole extending in the vertical direction. The second connecting member 362 has a second connecting hole 3621. The locking member 366 passes through the first connecting hole 3611 and the second connecting hole 3621 in sequence and is threadedly connected to the locking nut 367, thereby connecting the first connecting member 361 and the second connecting member 362. By setting the first connecting hole 3611 as a strip-shaped hole, there is a vertical movement between the first connecting member 361 and the second connecting member 362. Preferably, wear-resistant plates 368 are provided between the first connecting member 361 and the second connecting member 362, and between the head end of the first connecting member 361 and the locking member 366. More preferably, a pressure plate 369 is further provided between the head end of the locking member 366 and the corresponding wear-resistant plate 368. The first connecting member 361 has a first mounting plate 3612, which has a first mounting hole 3612a. The second connecting member 362 has a second mounting plate 3622, which has a second mounting hole 3622a. The mounting shaft 363 passes through the first mounting hole 3612a and the second mounting hole 3622a in sequence and is threadedly connected to the limiting nut 364. The elastic member 365 is sleeved on the mounting shaft 363 and is positioned in a compressed state between the head end of the first mounting plate 3612 and the mounting shaft 363. Because the elastic element 365 is in a compressed state, it will apply an upward force to the vertical drive module 33. Since the first connecting hole 3611 is a strip hole, there is a certain amount of movement between the first connecting element 361 and the second connecting element 362. Therefore, under the action of the elastic element 365, the vertical drive module 33 will push the upper slide rail upward, transferring a certain pressure to the upper slide rail and reducing the pressure on the lower slide rail.

[0056] The loading platform 34 is configured to unload goods into the cargo box 60 on its own side, and also to unload goods into the cargo box 60 on the opposite side. That is, the loading platform 34 can unload goods to both sides, improving the sorting efficiency.

[0057] Reference Figures 11 to 13The loading platform 34 includes a carriage 342, a loading platform body 34, and a moving drive assembly 345. The carriage 342 is connected to a vertical slider 331. A moving slide rail 343 is provided on the carriage 342 and is distributed along the width direction of the frame 10. A moving slider 344 is provided on the loading platform body 34 and is slidably connected to the moving slide rail 343. The moving drive assembly 345 is used to drive the loading platform body 34 to move along the moving slide rail 343 so that the loading platform body 34 can dock with the compartments 11 on both sides. When the loading platform body 34 aligns with the compartment 11 on its side, the loading platform body 34 does not need to move along the sliding rail 343. When the loading platform body 34 aligns with the compartment 11 on the opposite side, the loading platform body 34 needs to move along the sliding rail 343 towards the opposite compartment 11. After unloading goods into the opposite compartment 11, the loading platform body 34 will move back to its original position along the sliding rail 343. In this embodiment, the moving drive assembly 345 includes a moving motor 3451, a drive gear 3452, and a drive rack 3453. The moving motor 3451 is mounted on the carriage 342, the drive gear 3452 is mounted on the output shaft of the moving motor 3451, and the drive rack 3453 is mounted on the loading platform body 34. The drive rack 3453 is distributed along the width direction of the frame 10, and the drive rack 3453 meshes with the drive gear 3452 for transmission.

[0058] The loading platform body 34 includes a loading rack 3411, a drive shaft, a driven shaft, a conveyor belt 3412, and a conveyor drive assembly 3413. The drive shaft and the driven shaft are rotatably mounted on the loading rack 3411 and are spaced apart along the width direction of the frame 10. The conveyor belt 3412 is wound around the drive shaft and the driven shaft. The conveyor drive assembly 3413 is used to drive the drive shaft to rotate. The drive shaft drives the conveyor belt 3412 to transport goods so as to unload the goods into the corresponding compartment 11. The conveying drive assembly 3413 includes a conveying motor 3413a, a conveying drive wheel 3413b, a conveying driven wheel 3413d, and a conveying transmission belt 3413c. The conveying motor 3413a is mounted on the rack 3411, the conveying drive wheel 3413b is mounted on the output shaft of the conveying motor 3413a, the conveying driven wheel 3413d is mounted on the drive shaft, and the conveying transmission belt 3413c is wound around the conveying drive wheel 3413b and the conveying driven wheel 3413d.

[0059] In addition, refer to again Figure 1 and Figure 2The upper end of the frame 10 is provided with several indicator lights 70, each corresponding to a cargo box 60. The indicator lights 70 indicate the status of the corresponding cargo box 60. In one embodiment, the indicator lights 70 can indicate whether the corresponding cargo box 60 is full of goods. Specifically, the indicator lights 70 have a first state and a second state. When the indicator lights 70 are in the first state, it means that the corresponding cargo box 60 is not full of goods; when the indicator lights 70 are in the second state, it means that the corresponding cargo box 60 is full of goods. In one embodiment, the indicator lights 70 can also indicate whether the orders for the corresponding cargo box 60 are complete, or whether other conditional sets are satisfied. The indicator lights 70 have a first state and a second state. When the indicator lights 70 are in the first state, it means that the set of corresponding cargo boxes 60 is satisfied; when the indicator lights 70 are in the second state, it means that the set of corresponding cargo boxes 60 is not satisfied. In one embodiment, the indicator lights 70 can also indicate whether the cargo box 60 is in a normal state. The indicator light 70 has a first state and a second state. When the indicator light 70 is in the first state, it indicates that the corresponding cargo box 60 is in a normal state; when the indicator light 70 is in the second state, it indicates that the corresponding cargo box 60 is not in a normal state. In the above embodiment, the first state and the second state of the indicator light 70 can display different colors, or the light can be on in one state and off in the other state.

[0060] A display 90 is installed above the barcode scanning mechanism 40 in the frame 10 for displaying product information, etc. An electrical control cabinet is installed below the barcode scanning mechanism 40 in the frame 10 for controlling the overall equipment.

[0061] Along its length, the frame 10 has a door 80 on the opposite side of the upper packaging mechanism 20, the barcode scanning mechanism 40, the display 90, and the electrical control cabinet. The door 80 can be opened and closed. By setting the door 80, the broadcasting mechanism 30 can be protected and the maintenance of the broadcasting mechanism 30 can be facilitated.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
