Description

Technical Field

[0001] This invention relates to warehousing technology, specifically to material distribution equipment. Background Technology

[0002] The patent document with application publication number CN 115973642 A discloses an intelligent warehouse material automatic distribution equipment, including a feeding device, a discharging device, and a material tray conveying device arranged between the feeding device and the discharging device; a material hopper device is provided on one side of the material tray conveying device, and a material transfer device is also arranged between the material tray conveying device and the material hopper device.

[0003] The loading unit is equipped with a barcode scanner. During operation, empty trays are placed on the loading device beforehand. Then, the barcode scanner scans the corresponding work order code, and the backend obtains the type and quantity of materials to be allocated. Subsequently, the loading device conveys the empty trays to the tray conveyor, which then transports them to the allocation position and fixes the trays in place. The backend controls the hopper device to extend several trays carrying the corresponding type of materials toward the tray conveyor via the tray transmission mechanism. Then, the material transfer device is controlled to accurately locate the materials using a vision positioning mechanism. After accurate positioning, the materials are picked up and transferred to the corresponding trays. Once all the materials corresponding to the work order code have been transferred and allocated to the corresponding trays, the tray conveyor then transports them to the unloading device for unloading, thus completing the automated material allocation process.

[0004] In the aforementioned patent documents, a material transfer device needs to be installed between the silo device and the pallet conveying device. The material transfer device is a multi-axis industrial robot, equipped with a corresponding vision positioning system, which is costly and involves many steps in the material distribution process. Summary of the Invention

[0005] The technical problem solved by this invention is to simplify the structure of material distribution equipment and reduce the number of operation steps in material distribution.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an intelligent warehousing material distribution device, including a tray conveying device and a hopper device. The tray conveying device is arranged between a loading device and a unloading device. The hopper device includes several independently rotatable disc-shaped units. All disc-shaped units are arranged side by side, and the centers of all disc-shaped units are located on the same horizontal line. Each disc-shaped unit includes an annular outer shell, an annular inner shell, and several carrier trays located between the annular outer shell and the annular inner shell. The several carrier trays are connected by annular connectors. The several carrier trays are evenly distributed along the annular inner shell. The annular outer shell is provided with a material inlet, and the annular inner shell is provided with a material outlet. The tray conveying device passes through all disc-shaped units. The tray conveying device is provided with a tray, and the material outlet is located above the tray. The material outlet is provided with an opening and closing mechanism.

[0007] According to the above technical solution, an empty material tray is first placed on the feeding device. Then, the corresponding work order code is scanned by a barcode scanner, and the backend obtains the type and quantity of material to be allocated. The feeding device then conveys the empty material tray to the tray conveyor, which transports it to the allocation position, i.e., below the discharge port of the corresponding disc unit. The backend controls the rotation of the annular connector within the disc unit, which drives the carrier tray within the disc unit to rotate, displacing the required material to the discharge port. Afterwards, the backend controls the opening and closing mechanism to open the discharge port, allowing the material in the carrier tray to fall and be received by the tray. The opening and closing mechanism then closes the discharge port. The tray conveyor then conveys the material-laden tray to the unloading device for unloading.

[0008] The carrier tray is a container that is open at both the top and bottom. All carrier trays rotate with the annular connector and move to the inlet, where workers place the material into the tray. The upper part of the carrier tray is closed by an annular outer shell, and the bottom of the carrier tray is closed by an annular inner shell, containing the material within the tray. When the carrier tray rotates to the outlet, the opening and closing mechanism opens, and the material in the tray falls out under the influence of gravity.

[0009] Different disc-shaped units contain different types of materials on their trays. After scanning, under the control of the background system, the tray conveying device transports the empty tray to the corresponding disc-shaped unit to receive the corresponding material.

[0010] Compared to existing technologies that use industrial robots and corresponding vision positioning systems to distribute equipment, this invention can directly feed materials from the silo device into the trays on the tray conveyor. The structure is simplified, which not only saves costs and work space, but also improves work efficiency.

[0011] The annular outer shell is fixed to the bottom frame by the first leg. The front and rear edges of the annular connector protrude from the annular outer shell, and toothed rings are installed on the front and rear edges of the annular connector. The toothed rings are connected to the drive unit. Driven by the drive unit, the toothed rings rotate, which in turn drives the annular connector to rotate. The annular connector drives all the carrier disks on it to rotate, while the annular outer shell and the annular inner shell remain stationary.

[0012] The drive unit includes a driven gear meshing with a gear ring, a driving gear coaxial with the driven gear, and a motor driving the driving gear. A gear meshing with the driving gear is mounted on the motor shaft. Under the drive of the motor, the driving gear drives the driven gear, which in turn drives the gear ring to rotate. The control unit controls the rotation angle of the pallets within the disc-shaped unit by controlling the motor's movement, thus bringing the corresponding pallets to the discharge port. When the same disc-shaped unit is loaded with the same type of material, if all pallets are fully loaded, the annular connector only needs to rotate a fixed angle each time to move the material to the discharge port. If some pallets are empty, the control unit adjusts the rotation angle of the annular connector based on sensor feedback. For example, instead of rotating only 5 degrees, the annular connector needs to rotate 10 degrees due to an empty pallet, bringing the next pallet with material to the discharge port. The sensor is installed on the annular outer shell at the discharge port to monitor the presence or absence of material in the pallets.

[0013] An annular inner shell fits onto a cylindrical component, and the annular inner shell and the cylindrical component are fixedly connected. The cylindrical component is fixed to the bottom frame via a second support leg. A cylindrical component is placed between two adjacent annular inner shells, and adjacent sides of two adjacent annular inner shells fit onto the same cylindrical component. The material tray conveying device passes through the cylindrical component. All disc units are arranged sequentially, with a cylindrical component between two adjacent disc units to support adjacent sides of the annular inner shells of the two adjacent disc units.

[0014] The opening and closing mechanism includes an arc-shaped cover plate capable of closing the discharge port and a linear cylinder hinged to the arc-shaped cover plate. The linear cylinder is hinged to the inner wall of an annular inner shell, and an arc-shaped track is provided on the inner wall of the annular inner shell. The arc-shaped cover plate is movably fitted within the arc-shaped track. The linear cylinder is controlled by a control unit. Driven by the linear cylinder, the arc-shaped cover plate slides along the arc-shaped track to open or close the discharge port.

[0015] The material tray has a through hole. A vertical cylinder is mounted on the support of the material tray conveying device, located below the material tray. A receiving tray is mounted on the vertical cylinder, which can pass upward through the through hole to approach the discharge port. The feeding device conveys an empty material tray to the material tray conveying device, which then conveys it to below the discharge port of the corresponding disc-shaped unit. The control unit rotates the annular connector within the disc-shaped unit, causing the carrier plate within the unit to rotate, displacing the required material to the discharge port. Then, the control unit activates the vertical cylinder, driving the receiving tray to rise, passing upward through the through hole to below the discharge port. Next, the control unit activates the opening and closing mechanism, opening the discharge port and allowing the material in the carrier plate to fall onto the receiving tray. Then, driven by the vertical cylinder, the receiving tray descends and resets, allowing the material to fall onto the material tray. Finally, the opening and closing mechanism closes the discharge port. The material tray conveying device transports the material tray to the unloading device for unloading.

[0029] Combination Figure 4 , Figure 5An intelligent warehousing material distribution device includes a tray conveying device 10 and a hopper device 20. The tray conveying device is arranged between a loading device and a unloading device. The hopper device includes several independently rotatable disc units 30. All disc units are arranged side by side, and the centers of all disc units are located on the same horizontal line. Each disc unit includes an annular outer shell 31, an annular inner shell 32, and several carrier trays 33 located between the annular outer shell and the annular inner shell. The several carrier trays are connected by annular connectors 34. The several carrier trays are evenly distributed along the annular inner shell. The annular outer shell is provided with an inlet 311, and the annular inner shell is provided with an outlet 312. The tray conveying device passes through all disc units. The tray conveying device is provided with a tray 11, and the outlet is located above the tray. The outlet is provided with an opening and closing mechanism 40.

[0030] An empty material tray 11 is placed on the feeding device beforehand. Then, the corresponding work order code is scanned using a barcode scanner, allowing the backend to obtain the type and quantity of material to be allocated. The feeding device then transfers the empty tray 11 to the tray conveyor 10, which conveys it to the allocation position, below the discharge port 312 of the corresponding disc unit 30. The backend controls the rotation of the annular connector 34 within the disc unit 30, causing the carrier tray 33 within the disc unit to rotate, displacing the required material to the discharge port 312. Next, the backend controls the opening and closing mechanism 40 to open the discharge port 312, allowing the material in the carrier tray 33 to fall and be received by the tray. The opening and closing mechanism 40 then closes the discharge port 312. The tray conveyor 10 then transfers the material-laden tray 11 to the unloading device for unloading.

[0031] The carrier tray 33 is a container that is open at both the top and bottom. All carrier trays rotate with the annular connector 34 and arrive at the inlet 311, where workers place materials into the carrier tray 33. The upper part of the carrier tray is closed by the annular outer shell 31, and the bottom of the carrier tray is closed by the annular inner shell 32, containing the materials within the carrier tray. When the carrier tray rotates to the outlet 312, the opening and closing mechanism 40 opens, and the materials in the carrier tray 33 fall out under the action of gravity.

[0032] Different disc-shaped units 30 contain different types of materials on their respective trays 33. After scanning, under the control of the background system, the tray conveying device 10 transports the empty tray 11 to the corresponding disc-shaped unit 30 to receive the corresponding material.

[0033] The annular outer shell 31 is fixed to the bottom frame by the first support leg 313. The annular connector 34 protrudes from the annular outer shell on both its front and rear edges. Gear rings 35 are installed on the front and rear edges of the annular connector, and the gear rings are connected to the drive unit 36. Driven by the drive unit 36, the gear rings 35 rotate, which drives the annular connector 34 to rotate. The annular connector drives all the carrier disks 33 on it to rotate, while the annular outer shell 31 and the annular inner shell 32 remain stationary.

[0034] like Figure 5 The drive unit 36 ​​includes a driven gear 361 meshing with a gear ring 35, a driving gear 362 coaxial with the driven gear, and a motor 363 driving the driving gear. A gear meshing with the driving gear 362 is mounted on the motor shaft. Driven by the motor 363, the driving gear drives the driven gear 361, and the driven gear drives the gear ring 35 to rotate. The control unit controls the rotation angle of the trays 33 within the disc-shaped unit by controlling the movement of the motor 363, thus bringing the corresponding trays to the discharge port 312. When the same disc-shaped unit 30 is loaded with the same type of material, if all trays 33 are fully loaded, the annular connector 34 only needs to rotate a fixed angle each time to move the material to the discharge port. If some trays 33 are empty, the control unit adjusts the rotation angle of the annular connector 34 based on sensor feedback. For example, if it originally only needed to rotate 5 degrees, due to an empty tray, the annular connector 34 needs to rotate 10 degrees to bring the next tray carrying material to the discharge port. The sensor is installed on the annular housing 31 at the discharge port 312 to monitor the presence or absence of material in the carrier plate 33.

[0035] An annular inner shell 32 is fitted onto a cylindrical component 37, and the annular inner shell and the cylindrical component are fixedly connected. The cylindrical component is fixed to the bottom frame by a second support leg 371. A cylindrical component is placed between two adjacent annular inner shells, and the adjacent sides of two adjacent annular inner shells fit onto the same cylindrical component. The material tray conveying device 10 passes through the cylindrical component. All disc units 30 are arranged sequentially front to back, with a cylindrical component 37 between two adjacent disc units to support the adjacent sides of the annular inner shells of the two adjacent disc units.

[0036] like Figure 7 The opening and closing mechanism 40 includes an arc-shaped cover plate 41 capable of closing the discharge port 312 and a linear cylinder 42 hinged to the arc-shaped cover plate. The linear cylinder is hinged to the inner wall of the annular inner shell 32, and an arc-shaped track 43 is provided on the inner wall of the annular inner shell. The arc-shaped cover plate is movably fitted in the arc-shaped track. The linear cylinder 42 is controlled by the back end. Driven by the linear cylinder, the arc-shaped cover plate 41 slides along the arc-shaped track 43 to open or close the discharge port.

[0037] The material tray 11 is provided with a through hole 110. A vertical cylinder 13 is installed on the bracket 12 of the material tray conveying device 10. The vertical cylinder is located below the material tray. A receiving tray 14 is installed on the vertical cylinder. The receiving tray can pass upward through the through hole and approach the discharge port 312.

[0038] The feeding device transfers an empty tray 11 to the tray conveying device 10, which then conveys it to the area below the discharge port 312 of the corresponding disc-shaped unit. The control unit rotates the annular connector 34 within the disc-shaped unit 30, causing the carrier tray 33 within the unit to rotate, displacing the required material to the discharge port 312. Next, the control unit activates the vertical cylinder 13, which drives the receiving tray 14 to rise, passing upwards through the through hole 110 to the area below the discharge port 312. Then, the control unit activates the opening and closing mechanism 40, opening the discharge port 312 and allowing the material in the carrier tray 33 to fall onto the receiving tray 14. Subsequently, driven by the vertical cylinder 13, the receiving tray descends and resets, allowing the material to fall onto the tray 11. Finally, the opening and closing mechanism 40 closes the discharge port 312. The tray conveying device 10 then transfers the tray 11 containing the material to the unloading device for unloading.

[0039] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
