Description

Technical Field

[0001] This application relates to the field of logistics warehousing, and specifically proposes a fully automated device and method for flipping cages or bins to dump goods from the top. Background Technology

[0002] Currently, various automated transfer equipment is commonly used in the sorting areas of the e-commerce and express delivery industries to assist on-site personnel in handling large volumes of goods and inbound / outbound operations. Containers used in logistics transit hubs include mixed-pack cage carts or palletized bins. To improve centralized transfer efficiency, specialized equipment is provided for tipping over cage carts or large bins.

[0003] Existing container tipping systems generally employ top-opening unloading methods to facilitate the combined use of cage cars and hoppers. However, this approach has several drawbacks: Firstly, the tipping system uses a hydraulic drive, which is prone to oil leaks, leading to contamination of goods and equipment. Secondly, existing equipment is only suitable for containers with relatively uniform specifications and cannot meet the complex working conditions of containers with varying sizes. Furthermore, during tipping, if the containers are not properly clamped and positioned according to their dimensions, wobbling can occur, making it difficult to completely empty the goods at once. This still requires auxiliary personnel, resulting in relatively low overall transfer efficiency.

[0004] In view of the above, this patent application is hereby filed. Summary of the Invention

[0005] This application proposes an automatic cargo tilting device and method to solve the problems existing in the prior art by organically integrating the containers, loading and unloading and conveying devices of the container system, so as to effectively empty all the cargo at one time in the centralized transportation and unloading process, and then sort the mixed cargo that is poured out in sequence on the conveyor line.

[0006] To achieve the above design objectives, the top-tilting automatic cargo tilting device includes a tilting host assembly for inserting containers and tilting the containers to dump goods in batches, and a conveying assembly connected to one side of the tilting host assembly to receive the dumped goods and continuously output them; the containers carrying the batch of goods are sent to the tilting host assembly, and under the drive of the tilting drive device, the containers are tilted to the side of the conveying assembly. During this process, the goods are successively poured from the containers onto the conveying assembly.

[0007] Furthermore, the flipping host assembly has a frame assembly, a protective net assembly connected to one side of the frame assembly, and a frame assembly symmetrically and movably connected to the frame assembly on both sides for placing the container to carry the container and flip together; through the flipping drive assembly set on the frame assembly, the frame assembly can reciprocate around the connection point with the frame assembly to dump the goods in the container.

[0008] Furthermore, the frame assembly includes a frame body, on which a flip drive assembly and at least two sets of connecting support frames are provided for fixed connection and transmission of the frame assembly to reciprocate flipping.

[0009] Furthermore, the tilting drive assembly includes a geared motor, with the drive shaft horizontally connected to the frame via a first bearing and the driven shaft via a second bearing, and the output end of the geared motor drivingly connected to the drive shaft; two sets of transmission assemblies are symmetrically connected to both ends of the drive shaft and the driven shaft; each set of transmission assemblies includes a drive sprocket sleeved at the end of the drive shaft, driven sprockets sleeved at both ends of the driven shaft, and a series of tension sprockets mounted on the side of the frame, with a chain wound in a closed loop between the drive sprocket, the driven sprocket, and the tension sprockets; the connecting support frame is fixedly connected to the side of the driven sprocket.

[0010] Furthermore, the frame assembly includes a box-type container support frame with openings on one side and top. The container support frame is fixedly connected to the frame assembly. A top blocking assembly is movably connected to the top opening of the container support frame. A bottom locking assembly is provided at the bottom of the container support frame along at least one side of the side opening. At least one set of positioning photoelectric sensors is provided on the side of the container support frame.

[0011] Furthermore, the top blocking assembly is disposed at the junction of the top opening and the side opening of the container support frame, and includes two sets of first electric cylinders fixedly connected to the container support frame. The drive end of each set of first electric cylinders is fixedly connected to a set of top pressing brackets. At least one set of guide wheels is provided on the side of the top pressing brackets and slidably connected to the guide groove inside the container support frame. An array of pressing rollers is provided between the two sets of top pressing brackets.

[0012] Furthermore, at least one set of mirror photoelectric sensors is provided on the side of each set of top pressure brackets and vertically below the pressure rollers.

[0013] Furthermore, the bottom locking assembly includes a fixed plate fixedly connected to the container support frame, a second electric cylinder fixedly connected to the fixed plate via a support fixing seat, the drive end of the second electric cylinder being connected to the first connecting rod; the rear ends of the first and second connecting rods are respectively hinged to the fixed plate, and the front ends of the first and second connecting rods are respectively hinged to the third connecting rod.

[0014] Based on the structural design of the above-mentioned top-tilting automatic cargo tilting device, this application proposes the following top-tilting automatic cargo tilting method: a container carrying a batch of goods is fed into the tilting host assembly, the top blocking assembly presses down on the top of the container vertically, and the bottom locking assembly positions the bottom of the container from one or both sides; under the drive of the tilting drive device, the container is tilted to one side of the conveying assembly; the container remains relatively stationary with respect to the container support frame during the tilting process, and the goods are successively tilted from the container onto the conveying assembly, and the goods are sequentially conveyed and sorted on the conveying assembly.

[0015] Furthermore, the conveying component is a belt conveyor consisting of two connected sections. An array of photoelectric sensors is installed at the connection between the two sections of the belt conveyor to detect the conveying speed and / or conveying volume of the goods. The PLC then issues control commands to adjust the running speed of each section of the belt conveyor and adjust the running speed of the rotating host component to drive the container to rotate.

[0016] In summary, the top-tilting automatic cargo tilting device and method described in this application have the following advantages:

[0017] 1. This application, through the combined use of top clamping and bottom locking mechanisms, can effectively position and clamp containers of different specifications and dimensions, making it more flexible and effective for various types of containers and significantly improving the overall efficiency of transfer operations;

[0018] 2. This application addresses larger containers by enabling a more reliable positioning of the clamping and locking mechanism during the pouring process, preventing the container from shaking or changing its tilt angle, and ensuring that all batches of goods are emptied at once.

[0019] 3. The flipping drive device of this application preferably uses a sprocket and chain drive assembly, which is easier to maintain than the prior art, has better transmission performance, and can avoid oil leakage. Attached Figure Description

[0029] Example 1, such as Figures 1 to 8 As shown, the top-tilting automatic cargo tilting device includes a tilting host assembly 1 for inserting a container 10 and tilting the container 10 to dump cargo in batches, and a conveying assembly 2 connected to one side of the tilting host assembly 1 to receive the dumped cargo and continuously output it.

[0030] In this process, the container 10 carrying a batch of goods is sent to the tilting host assembly 1. Driven by the tilting drive device, the container 10 is tilted to one side of the conveying assembly 2. During this process, the goods are poured from the container 10 onto the conveying assembly 2.

[0031] The belt conveyor assembly 2 is preferably a two-section belt conveyor. Baffles are provided on both sides of each section of the belt conveyor. An array of photoelectric sensors is provided at the junction of the two sections of the belt conveyor to detect the conveying speed and / or conveying volume of goods. Then, the PLC issues control commands to adjust the running speed of each section of the belt conveyor and adjust the running speed of the rotating host assembly 1 and the rotating container 10.

[0032] The aforementioned flipping host assembly 1 has a frame assembly 1.1, a protective net assembly 1.3 connected to one side of the frame assembly 1.1, and a frame assembly 1.2 for placing the container 10 to support the container 10 and flipping together. The frame assembly 1.2 is symmetrically and movably connected to the frame assembly 1.1 on both sides. Through the flipping drive assembly provided on the frame assembly 1.1, the frame assembly 1.2 can reciprocate around the connection point with the frame assembly 1.1 to dump the goods in the container 10.

[0033] The protective net assembly 1.3 can be fixed to the ground with an array of expansion bolts to isolate the flipping work area from the external working environment and prevent goods from falling and injuring on-site personnel; control devices such as electrical control cabinets can also be set on the outside of the protective net assembly 1.3 for easy maintenance.

[0034] The frame assembly 1.1 includes a frame body 1.1.1, on which a flipping drive assembly and at least two sets of connecting support frames 1.1.11 are provided for fixing and driving the frame assembly 1.2 to reciprocate and flip.

[0035] The aforementioned flipping drive assembly can be designed as a lifting electric cylinder assembly, an electric cylinder connecting rod assembly, a sprocket and chain assembly, a planetary gear assembly, a rotary chain assembly, etc. In this embodiment, the drive transmission scheme of the sprocket and chain assembly is preferred.

[0036] Specifically, the frame 1.1.1 is fixed to the ground with expansion bolts. A geared motor 1.1.12 is mounted on the frame 1.1.1 via a motor mounting bracket 1.1.2. The drive shaft 1.1.3 is horizontally connected to the frame 1.1.1 via a first bearing 1.1.8, and the driven shaft 1.1.9 is horizontally connected to the driven shaft 1.1.1 via a second bearing 1.1.10. The output end of the geared motor 1.1.12 is connected to the drive shaft 1.1.3. The drive shaft 1.1.3 and the driven shaft 1.1.9 are respectively... Two sets of transmission components are symmetrically connected. Each set of transmission components includes a drive sprocket 1.1.4 sleeved at the end of the drive shaft 1.1.3, a driven sprocket 1.1.6 sleeved at both ends of the driven shaft 1.1.9, and an array of tension sprockets 1.1.7 mounted on the side of the frame 1.1.1. A chain 1.1.5 is wound in a closed loop between the drive sprocket 1.1.4, the driven sprocket 1.1.6, and the tension sprocket 1.1.7. The connecting support frame 1.1.11 is fixedly connected to the side of the driven sprocket 1.1.6.

[0037] The driving sprocket 1.1.4 has a smaller radius, while the driven sprocket 1.1.6 has a larger radius. The larger driven sprocket 1.1.6 is used to achieve a fixed connection with the frame assembly 1.2 through components such as a fixed wheel frame, thereby obtaining a larger overturning force for the frame assembly 1.2 and the container 10 through the transmission ratio between the large and small sprockets.

[0038] Driven by the geared motor 1.1.12, and through the transmission of the drive shaft 1.1.3, the two sets of transmission components on the side of the frame 1.1.1 simultaneously drive the two sets of connecting support frames 1.1.11 to rotate, thereby transmitting the tilting power to the container 10 through the frame assembly 1.2. During the tilting process, the frame assembly 1.2, together with the container 10, reciprocates around the axial center of the driven shaft 1.1.9 to achieve the cage tilting operation. Among them, the driving sprocket 1.1.4 and the driven sprocket 1.1.6 are driven by the chain 1.1.5, and the chain 1.1.5 is tensioned by the tensioning sprocket 1.1.7.

[0039] The frame assembly 1.2 includes a box-type container support frame 1.2.1 with openings on one side and top. The container support frame 1.2.1 is fixedly connected to the frame assembly 1.1 (specifically, to the connecting support frame 1.1.11). A top blocking assembly 1.2.2 is movably connected to the top opening of the container support frame 1.2.1. A bottom locking assembly 1.2.3 is provided at least on the bottom of the container support frame 1.2.1 along at least one side of the side opening. At least one set of positioning photoelectric sensors 1.2.4 is provided on the side of the container support frame 1.2.1.

[0040] The top blocking assembly 1.2.2 is located at the junction of the top opening and the side opening of the container support frame 1.2.1. It includes two sets of first electric cylinders 1.2.2.3 fixedly connected to the container support frame 1.2.1 via a first electric cylinder tailstock 1.2.2.4. The driving end of each set of first electric cylinders 1.2.2.3 is fixedly connected to a set of top pressing brackets 1.2.2.1 via a first electric cylinder fixing seat 1.2.2.5. At least one set of guide wheels 1.2.2.2 are provided on the side of the top pressing brackets 1.2.2.1 and are slidably connected to the guide grooves (not shown in the figure, which may be symmetrically distributed on the side of the container support frame 1.2.1). An array of pressing rollers 1.2.2.7 of different lengths are provided between the two sets of top pressing brackets 1.2.2.1. Under the synchronous drive of the two sets of first electric cylinders 1.2.2.3, the top pressing bracket 1.2.2.1 drives the pressing roller 1.2.2.7 to run vertically along the guide groove of the container support frame 1.2.1. When the container 10 carrying a batch of goods is fed into the container support frame 1.2.1 from the side opening, the pressing roller 1.2.2.7 presses down on a part of the top opening of the container 10 vertically. This ensures that the container 10 remains relatively stationary with the container support frame 1.2.1 during the flipping process, and also does not completely block the top opening of the container 10 so as not to affect the goods from being poured out of the top opening of the container 10.

[0041] Furthermore, at least one set of mirror-reflective photoelectric sensors 1.2.2.6 is provided on the side of each set of top pressing brackets 1.2.2.1 and vertically below the pressing rollers 1.2.2.7. When the top pressing brackets 1.2.2.1 and the pressing rollers 1.2.2.7 descend vertically to above the top of the container 10, the mirror-reflective photoelectric sensors 1.2.2.6 can detect the accumulated and protruding goods inside the container 10 or the top of the container 10, thereby triggering a pressing-in signal. The pressing-in signal is fed back to the PLC, which sends a stop control signal to the first electric cylinder 1.2.2.3, and the pressing rollers 1.2.2.7 press down on the goods or the top of the container 10.

[0042] The bottom locking assembly 1.2.3 includes a fixing plate 1.2.3.1 fixedly connected to the container support frame 1.2.1. A second electric cylinder 1.2.3.3 is fixedly connected to the fixing plate 1.2.3.1 via a support fixing seat 1.2.3.2. The driving end of the second electric cylinder 1.2.3.3 is connected to the first connecting rod 1.2.3.6 via an ear plate 1.2.3.4. The rear ends of the first connecting rod 1.2.3.6 and the second connecting rod 1.2.3.7 are respectively hinged to the fixing plate 1.2.3.1 via a fixing seat 1.2.3.5. The front ends of the first connecting rod 1.2.3.6 and the second connecting rod 1.2.3.7 are respectively hinged to the third connecting rod 1.2.3.8. Driven by the second electric cylinder 1.2.3.3, the bottom locking assembly 1.2.3 can be flexibly extended from one side of the bottom into the container support frame 1.2.1, or retracted from the container support frame 1.2.1 to exit its working state. Specifically, in the initial state, the second electric cylinder 1.2.3.3 drives the first connecting rod 1.2.3.6 to move away from the container support frame 1.2.1. Under the combined action of the second connecting rod 1.2.3.7, the third connecting rod 1.2.3.8 is retracted to the outside of the container support frame 1.2.1. When the container 10 is fed into the container support frame 1.2.1, the PLC sends a start-up signal to the second electric cylinder 1.2.3.3, and the second electric cylinder 1.2.3.3 extends the first connecting rod 1.2.3.6 forward. Under the combined action of the second connecting rod 1.2.3.7, the third connecting rod 1.2.3.8 is retracted to the outside of the container support frame 1.2.1. When the container 10 is fed into the container support frame 1.2.1, the PLC sends a start-up signal to the second electric cylinder 1.2.3.3. The second electric cylinder 1.2.3.3 then extends the first connecting rod 1.2.3.6 forward. Under the action, the third link 1.2.3.8 is extended forward and into the interior of the container support frame 1.2.1 through the opening on the side of the container support frame 1.2.1 (not shown in the figure) to hook the bottom of the container 10 (if the container 10 is a cage cart, the third link 1.2.3.8 can hook or block the bottom casters of the cage cart; if the container 10 is a material box, the third link 1.2.3.8 can hook or block the pallet carrying the material box); therefore, the bottom locking assembly 1.2.3 can effectively ensure that the container 10 remains relatively stationary with respect to the container support frame 1.2.1 during the overturning process.

[0043] like Figure 7As shown, this describes the process of locking the container 10 from its bottom. Figure 7 (A) and Figure 7 As shown in (B), initially, container 10 is sent into container support frame 1.2.1, and the third link 1.2.3.8 of bottom locking assembly 1.2.3 is located outside container support frame 1.2.1 and does not contact container 10;

[0044] like Figure 7 (C) and Figure 7 As shown in (D), after the detection signal of the photoelectric sensor 1.2.2.6 is triggered, the PLC sends a start-up signal to the second electric cylinder 1.2.3.3. The second electric cylinder 1.2.3.3 sends the first connecting rod 1.2.3.6 forward. Under the combined action of the second connecting rod 1.2.3.7, the third connecting rod 1.2.3.8 is pushed forward and extends into the container support frame 1.2.1 through the opening on the side of the container support frame 1.2.1 until it hooks or blocks the bottom of the container 10. Thus, the container 10 can always remain relatively stationary with respect to the container support frame 1.2.1 during the flipping process.

[0045] Based on the structural design of the above-mentioned top-tilting automatic cargo tilting device, this application proposes the following top-tilting automatic cargo tilting method:

[0046] A container 10 carrying a bulk of goods is fed into the tilting host assembly 1. The top blocking assembly 1.2.2 presses the top of the container 10 vertically downward, and the bottom locking assembly 1.2.3 positions the bottom of the container 10 from one or both sides.

[0047] Driven by the flipping drive device, the container 10 is flipped toward the conveying component 2. During the flipping process, the container 10 remains relatively stationary with respect to the container support frame 1.2.1. Goods are poured from the container 10 onto the conveying component 2. The goods are then conveyed forward and sorted on the conveying component 2 in sequence.

[0048] Furthermore, the conveying component 2 is a belt conveyor consisting of two connected sections. An array of photoelectric sensors is installed at the connection between the two sections of the belt conveyor to detect the conveying speed and / or conveying volume of the goods. Then, the PLC issues control commands to adjust the running speed of each section of the belt conveyor and adjust the running speed of the rotating host component 1 to rotate the container 10.

[0049] Specifically, the front and rear conveyor belts differ in height and conveying speed. The front conveyor belt has a higher conveying surface but a slower conveying speed. The conveying pattern of goods on the front and rear conveyor belts gradually changes from 3D flow to 2D flow.

[0050] like Figure 8As shown, taking the use of a cage truck as an example, the automatic tipping method for cargo includes the following implementation steps:

[0051] Step (1) Initialization;

[0052] like Figure 8 (A) The cage car is sent into the container support frame 1.2.1, and the positioning photoelectric sensor 1.2.4 detects and feeds back the positioning information;

[0053] Step (2) Container positioning;

[0054] like Figure 8 (B) After the PLC confirms that container 10 is in place, the top blocking component 1.2.2 and the bottom locking component 1.2.3 operate simultaneously;

[0055] The top blocking assembly 1.2.2 presses vertically downwards until the mirror photoelectric sensor 1.2.2.6 detects the accumulated and protruding goods inside the container 10, or the top of the container 10, triggering a pressing-in signal. The pressing-in signal is fed back to the PLC, which sends a stop control signal to the first electric cylinder 1.2.2.3. The pressing roller 1.2.2.7 presses down on the goods or the top of the container 10, achieving a fixed limit from the top of the container 10.

[0056] The second electric cylinder 12.3.3 of the bottom locking assembly 12.3 extends the first connecting rod 12.3.6 forward. Under the combined action of the second connecting rod 12.3.7, the two sets of third connecting rods 12.3.8 are respectively extended forward and through the opening on the side of the container support frame 12.1 into the interior of the container support frame 12.1, thereby clamping the container 10 from both sides and fixing it to a fixed position.

[0057] Step (3) Tilting and tilting;

[0058] The geared motor 1.1.12 drives the drive shaft 1.1.3 to rotate, and the two sets of transmission components simultaneously drive the two sets of connecting support frames 1.1.11 to rotate. The flipping power is transmitted to the container 10 through the frame assembly 1.2. During the flipping process, the frame assembly 1.2 together with the container 10 reciprocates around the axial center of the driven shaft 1.1.9, and the container 10 and the container support frame 1.2.1 remain relatively stationary.

[0059] After container 10 is rotated 90°, the goods begin to fall downwards onto conveyor assembly 2;

[0060] Step (4) Empty the container;

[0061] When the photoelectric sensor detects that the goods have fallen onto the conveyor assembly 2, the conveyor assembly 2 starts to operate and conveys the goods forward.

[0062] When the frame component 1.2, together with the container 10, is flipped to 120°, all the goods inside the container 10 are emptied at once;

[0063] Reverse the steps described above, and the frame component 1.2 carrying container 10 will flip back to its initial position.

[0064] As described above, the embodiments given in conjunction with the accompanying drawings are merely preferred solutions for achieving the objectives of this invention. Those skilled in the art can draw inspiration from this and directly derive other alternative structures that conform to the design concept of this invention. Other structural features derived therefrom should also fall within the scope of the solutions described in this invention.
