Description

Technical Field

[0001] This application relates to the field of logistics warehousing, and specifically provides a fully automatic device and method for tipping a cage cart or a bin to pour out goods from the top. Background Art

[0002] Currently, various automated transfer devices are usually used at the sorting sites in the e-commerce and express delivery industries to cooperate with on-site personnel to implement large-volume goods transfer processing and inbound and outbound operations. For example, the containers used in logistics transfer yards include mixed cage carts or bins with pallets at the bottom. To improve the centralized transfer efficiency, equipment dedicated to tipping cage carts or large-sized bins is correspondingly configured.

[0003] The tipping devices of existing container systems generally adopt the top-opening method for convenient combined use of cage carts and bins, and mainly have the following deficiencies and disadvantages: On the one hand, the tipping power system of the tipping device uses a hydraulic drive type for tipping, so oil leakage is likely to occur, causing pollution to goods and equipment. On the other hand, existing equipment is only suitable for containers with relatively single specifications and cannot meet the complex working conditions with inconsistent container specification types. In addition, during the tipping process, the container is not clamped and positioned according to the specification size, and it is easy to shake, resulting in the goods in the container being difficult to be completely emptied at one time, and auxiliary operators still need to be equipped, and the overall transfer efficiency is still low.

[0004] In view of this, this patent application is specifically proposed. Summary of the Invention

[0005] This application provides a top-tipping automatic goods tipping device and its method, aiming to solve the problems existing in the above-mentioned prior art by organically integrating the containers, loading and unloading, and conveying devices of the container system, so as to effectively empty all goods at one time in the centralized transportation and unloading links, and then the mixed goods poured out are sorted sequentially on the conveyor line.

[0006] To achieve the above design purpose, the top-tipping automatic goods tipping device includes a tipping main machine component for placing a container and tipping the container to pour out goods in batches, and a conveying component connected to one side of the tipping main machine component to receive the poured-out goods and continuously output them; the container carrying a batch of goods is sent into the tipping main machine component, and under the drive of the tipping drive device, the container is tipped to the side of the conveying component, and during this process, the goods are successively poured from the container onto the conveying component.

A chain is wound in a closed loop between the driving sprocket, the driven sprocket, and the tensioning sprockets; the connection support frame is fixedly connected to the side of the driven sprocket.

[0010] Further, the frame assembly includes a box - type container support frame with openings on one side and the 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 arranged at least on one side along the side opening at the bottom of the container support frame. At least one set of in - place photoelectric sensors is arranged on the side of the container support frame.

[0011] Further, the top blocking assembly is arranged at the connection of the top opening and the side opening of the container support frame. It includes two sets of first electric cylinders fixedly connected to the container support frame. The driving 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 slidably connected to the inside of the guide groove of the container support frame is arranged on the side of the top pressing brackets. Several sets of pressing rollers are arranged between the two sets of top pressing brackets.

[0012] Further, at least one set of mirror - reflecting photoelectric sensors is arranged on the side of each set of top pressing brackets, vertically below the pressing rollers.

[0013] Further, the bottom locking assembly includes a fixing plate fixedly connected to the container support frame. A second electric cylinder is fixedly connected to the fixing plate through a support fixing seat. The driving end of the second electric cylinder is connected to a first connecting rod; the rear ends of the first connecting rod and the second connecting rod are respectively hinged to the fixing plate, and the front ends of the first connecting rod and the second connecting rod are respectively hinged to a third connecting rod.

[0029] Example 1, as Figures 1 to 8 shown, the top-tipping type automatic goods dumping device described includes a flipping main machine assembly 1 for placing the container 10 and flipping the container 10 to batch dump the goods, and a conveying assembly 2 connected to one side of the flipping main machine assembly 1 to receive the dumped goods and continuously output them.

[0030] Among them, the container 10 carrying a batch of goods is sent into the flipping main machine assembly 1, and under the drive of the flipping drive device, the container 10 is flipped towards the conveying assembly 2. During this process, the goods are successively dumped from the container 10 onto the conveying assembly 2.

[0031] The belt conveying assembly 2 is preferably a two-stage belt conveyor, with baffles provided on both sides of each stage of the belt conveyor, and a plurality of groups of photoelectric sensors are provided at the connection of the two-stage belt conveyors to detect the goods conveying speed and / or the conveying volume, and then the PLC issues a control instruction to adjust the running speed of each stage of the belt conveyor and the running speed of the flipping main machine assembly 1 for driving the container 10 to flip.

[0032] The flipping main machine assembly 1 has a frame assembly 1.1, a guard net assembly 1.3 is connected to one side of the frame assembly 1.1, and both sides of the frame assembly 1.2 for placing the container 10 and carrying the container 10 to flip together are symmetrically and movably connected to the frame assembly 1.1; through the flipping drive assembly provided on the frame assembly 1.1, the frame assembly 1.2 can reciprocally flip around the connection point with the frame assembly 1.1 to dump the goods in the container 10.

[0033] Among them, the guard net assembly 1.3 can be fixed to the ground by array expansion bolts to isolate the flipping work area from the external operation environment, preventing goods from falling and injuring on-site personnel; also, control devices such as the electric control cabinet can be arranged outside the guard net assembly 1.3 for convenient 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 for fixedly connecting and driving the frame assembly 1.2 to reciprocally flip are provided;

[0035] The flipping drive assembly can be designed in ways such as a jacking type electric cylinder assembly, an electric cylinder connecting rod assembly, a sprocket chain assembly, a planetary gear assembly, a rotary chain assembly, etc. In this embodiment, the drive transmission scheme of the sprocket chain assembly is preferably selected.

[0036] Specifically, the frame body 1.1.1 is fixed to the ground by expansion bolts. A reduction motor 1.1.12 is fixedly installed on the frame body 1.1.1 through a motor mounting base 1.1.2. A drive shaft 1.1.3 is horizontally axially connected to the frame body 1.1.1 through a first pedestal bearing 1.1.8, and a driven shaft 1.1.9 is horizontally axially connected to the frame body 1.1.1 through a second pedestal bearing 1.1.10. The output end of the reduction motor 1.1.12 is drivingly connected to the drive shaft 1.1.3; Two sets of transmission components are symmetrically connected to both ends of the drive shaft 1.1.3 and the driven shaft 1.1.9 respectively. Each set of transmission components includes a driving sprocket 1.1.4 sleeved on the end of the drive shaft 1.1.3, a driven sprocket 1.1.6 sleeved on both ends of the driven shaft 1.1.9, and several sets of tensioning sprockets 1.1.7 axially arranged on the side of the frame body 1.1.1. A chain 1.1.5 is wound in a closed loop between the driving sprocket 1.1.4, the driven sprocket 1.1.6, and the tensioning 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, and the driven sprocket 1.1.6 has a larger radius. The larger driven sprocket 1.1.6 is used to realize the fixed connection with the frame assembly 1.2 through components such as a fixed wheel frame, so as to obtain a larger flipping power for the frame assembly 1.2 and the container 10 through the transmission ratio between the large and small sprockets.

[0038] Driven by the reduction motor 1.1.12, through the transmission cooperation of the drive shaft 1.1.3, two sets of transmission components on the side of the frame 1.1.1 drive two sets of connecting support frames 1.1.11 to rotate simultaneously, so as to transfer the flipping power to the container 10 through the frame assembly 1.2; during the flipping process, the frame assembly 1.2 together with the container 10 reciprocally flips around the axial center of the driven shaft 1.1.9 to achieve the cage inversion operation. Among them, the driving sprocket 1.1.4 and the driven sprocket 1.1.6 are driven through the chain 1.1.5, and the chain 1.1.5 is tensioned through the tensioning sprocket 1.1.7.

[0039] The described frame assembly 1.2 includes a box-type container support frame 1.2.1 with openings on one side and the 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). At the top opening of the container support frame 1.2.1, a top blocking assembly 1.2.2 is movably connected. At the bottom of the container support frame 1.2.1, at least one side along the side opening is provided with a bottom locking assembly 1.2.3. At least one set of in-place photoelectric sensors 1.2.4 is provided on the side of the container support frame 1.2.1.

[0040] The described top blocking assembly 1.2.2 is arranged at the connection 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 through the 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 through the first electric cylinder fixing seat 1.2.2.5. At least one set of guide wheels 1.2.2.2 is arranged on the side of the top pressing bracket 1.2.2.1 and slidably connected inside the guide groove (not shown in the figure, and the guide groove can be symmetrically distributed on the side of the container support frame 1.2.1) of the container support frame 1.2.1. Between the two sets of top pressing brackets 1.2.2.1, several groups of pressing rollers 1.2.2.7 with different lengths are arranged. 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 rollers 1.2.2.7 to move vertically along the guide groove of the container support frame 1.2.1. When the container 10 carrying a batch of goods inside is fed into the container support frame 1.2.1 from the side opening, the pressing rollers 1.2.2.7 press down a part of the top opening of the container 10 vertically, so that it can not only ensure the relative static state of the container 10 and the container support frame 1.2.1 during the flipping process, but also not completely block the top opening of the container 10 and not affect the dumping of goods from the top opening of the container 10.

[0041] Further, at least one set of mirror-reflective photoelectric sensors 1.2.2.6 is provided below the side of each top pressing bracket 1.2.2.1 and vertically below the pressing roller 1.2.2.7. When the top pressing bracket 1.2.2.1 together with the pressing roller 1.2.2.7 descends vertically above the top of the container 10, the mirror-reflective photoelectric sensors 1.2.2.6 can detect the goods piled up and protruding inside the container 10 or the top of the container 10, thereby triggering a signal indicating that the pressing is in place; the signal indicating that the pressing is in place is fed back to the PLC, and the PLC sends a control signal to the first electric cylinder 1.2.2.3 to stop running, and the pressing roller 1.2.2.7 presses 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 through 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 through 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 through a fixing seat 1.2.3.5, and 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 switched between a working state of extending from one side of the bottom into the container support frame 1.2.1 or retracting from inside the container support frame 1.2.1 to withdraw. Specifically, in the initial state, the second electric cylinder 1.2.3.3 drives the first connecting rod 1.2.3.6 to move to a position 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 backward to the outside of the container support frame 1.2.1; after the container 10 is sent into the container support frame 1.2.1, the PLC sends a start 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 sent forward and extends into the container support frame 1.2.1 through an opening (not shown in the figure) on the side of the container support frame 1.2.1 to hook the bottom of the container 10 (if the container 10 is a cage car, the third connecting rod 1.2.3.8 can hook or block the bottom casters of the cage car; if the container 10 is a storage box, the third connecting rod 1.2.3.8 can hook or block the tray carrying the storage 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 flipping process.

[0043] Such as Figure 7As shown, the process of locking the container 10 from its bottom is as follows. As Figure 7 (A) and Figure 7 (B) show, initially, the container 10 is sent into the container support frame 1.2.1. The third link 1.2.3.8 of the bottom locking assembly 1.2.3 is outside the container support frame 1.2.1 and does not contact the container 10.

[0044] As Figure 7 (C) and Figure 7 (D) show, after triggering the detection signal of the mirror reflection photoelectric sensor 1.2.2.6, the PLC sends a start signal to the second electric cylinder 1.2.3.3. The second electric cylinder 1.2.3.3 sends the first link 1.2.3.6 forward. Under the combined action of the second link 1.2.3.7, the third link 1.2.3.8 is sent forward and extends 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 until it hooks or blocks the bottom of the container 10, so that 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 above structural design of the top-tipping type automatic goods dumping device, the present application proposes the following top-tipping type automatic goods dumping method:

[0046] The container 10 carrying a batch of goods is sent into the flipping main unit assembly 1. The top blocking assembly 1.2.2 presses down on the top of the container 10 vertically, and the bottom locking assembly 1.2.3 positions the bottom of the container 10 from one side or both sides.

[0047] Driven by the flipping drive device, the container 10 is flipped towards the conveying assembly 2. The container 10 always remains relatively stationary with respect to the container support frame 1.2.1 during the flipping process, and the goods are successively dumped from the container 10 onto the conveying assembly 2. The goods are successively conveyed forward and sorted on the conveying assembly 2.

[0048] Furthermore, the conveying assembly 2 is a belt conveyor composed of two sections connected in series. A plurality of groups of photoelectric sensors are arranged at the connection between the two belt conveyors to detect the conveying speed and / or conveying volume of the goods, and then the PLC issues control instructions to adjust the running speed of each section of the belt conveyor and the running speed of the flipping main unit assembly 1 for driving the container 10 to flip.

[0049] Specifically, there are differences in both height and conveying speed between the front section belt conveyor and the rear section belt conveyor. The conveying surface height of the front section belt conveyor is higher, but the conveying speed is slower. The conveying state of the goods flow gradually changes from 3D flow to 2D flow on the front and rear section belt conveyors.

[0050] As Figure 8As shown in the figure, taking the use of a cage truck as an example, the top-down automatic dumping method for goods includes the following implementation steps:

[0051] Step (1) Initialization;

[0052] As Figure 8 (A), the cage truck is sent into the container support frame 1.2.1, and the in-place photoelectric sensor 1.2.4 detects and feeds back the in-place information;

[0053] Step (2) Container positioning;

[0054] As Figure 8 (B), after the PLC confirms that the 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 component 1.2.2 presses down vertically until the mirror reflection photoelectric sensor 1.2.2.6 detects the goods piled up and protruding inside the container 10 or the top of the container 10 to trigger the downward pressing in-place signal; the downward pressing in-place signal is fed back to the PLC, and the PLC sends a control signal to stop the operation to the first electric cylinder 1.2.2.3, and the downward pressing roller 1.2.2.7 presses the goods or the top of the container 10 to achieve fixed limit from the top of the container 10;

[0056] The second electric cylinder 1.2.3.3 of the bottom locking component 1.2.3 sends out the first connecting rod 1.2.3.6 forward. Under the combined action of the second connecting rod 1.2.3.7, the two groups of third connecting rods 1.2.3.8 are respectively sent forward and extend into the inside of the container support frame 1.2.1 from the side through the openings on the side of the container support frame 1.2.1, so as to achieve clamping and fixing the container 10 from both sides;

[0057] Step (3) Tipping and dumping;

[0058] The reduction motor 1.1.12 drives the drive shaft 1.1.3 to rotate, and the two groups of transmission components drive the two groups of connecting support frames 1.1.11 to rotate at the same time. The tipping power is transmitted to the container 10 through the frame component 1.2; during the tipping process, the frame component 1.2 together with the container 10 reciprocally tips around the axial center of the driven shaft 1.1.9, and the container 10 remains relatively stationary with the container support frame 1.2.1;

[0059] When the container 10 is tipped 90°, the goods start to fall downward onto the conveying component 2;

[0060] Step (4) Emptying the container;

[0061] When the photoelectric sensor detects that the goods have fallen onto the conveying component 2, the conveying component 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 one time;

[0063] Running in reverse according to the above steps, the frame component 1.2 carries the container 10 and flips it back to the initial position.

[0064] As described above, the embodiments given in the accompanying drawings are only the preferred solutions for realizing the purpose of the present invention. For those skilled in the art, they can get inspiration therefrom and directly derive other alternative structures that conform to the design concept of the present invention. The other structural features thus obtained should also fall within the scope of the solutions described in the present invention.
