[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] This application provides an unloading device, such as... Figures 1-2 As shown, the unloading device includes a frame 10, at least one open container 20, and at least one tipping mechanism; Figures 3-5 As shown, the tipping mechanism includes a vertical guide rail 31, a vertical slider 32, a horizontal guide rail 33, and a horizontal slider 34. The vertical guide rail 31 is fixed on the frame 10 and extends vertically. The vertical slider 32 is slidably mounted on the vertical guide rail 31. The horizontal guide rail 33 is fixed on the frame 10 and extends horizontally. The horizontal guide rail 33 is located on one side of the vertical guide rail 31 along the vertical direction. The horizontal slider 34 is slidably mounted on the horizontal guide rail 33. The horizontal and vertical directions are perpendicular to each other and lie in the same plane. The cargo drum 20 is rotatably connected to the vertical slider 32 via a first rotating shaft. The cargo drum 20 is rotatably connected to the horizontal slider 34 via a second rotating shaft. The axes of the first and second rotating shafts are both perpendicular to the vertical and horizontal directions (i.e., the axes of the first and second rotating shafts are perpendicular to the vertical and horizontal directions, respectively, and the axes of the second rotating shafts are perpendicular to the vertical and horizontal directions, respectively).

[0030] The phrase "the horizontal guide rail 33 is located on one side of the vertical guide rail 31 along the vertical direction" means that the horizontal guide rail 33 is located on either side of the vertical guide rail 31 along the vertical direction. In other words, the horizontal guide rail 33 can be located on the left side of the vertical guide rail 31 along the vertical direction, or it can be located on the right side of the vertical guide rail 31 along the vertical direction.

[0031] The unloading device provided by the embodiment of the application is characterized in that the rack 10 is provided with a vertical guide rail 31 extending in the vertical direction and a horizontal guide rail 33 extending in the horizontal direction, the horizontal guide rail 33 is located on one side of the vertical guide rail 31 in the vertical direction, the vertical guide rail 31 is provided with a vertical sliding block 32 which is slidable, the horizontal guide rail 33 is provided with a horizontal sliding block 34 which is slidable, and the horizontal sliding direction is in the same plane as the vertical direction. The bucket 20 is connected to the vertical sliding block 32 through a first rotating shaft, and the bucket 20 is connected to the horizontal sliding block 34 through a second rotating shaft. The axis of the first rotating shaft and the axis of the second rotating shaft are both perpendicular to the vertical direction and the horizontal direction. When the vertical sliding block 32 moves along the vertical guide rail 31, the vertical sliding block 32 and the horizontal sliding block 34 are both connected to the bucket 20, so that the vertical sliding block 32 drives the horizontal sliding block 34 to move along the horizontal guide rail 33 when the vertical sliding block 32 moves, thereby driving the bucket 20 to rotate around the first rotating shaft and the second rotating shaft at the same time, realizing the overturning and dumping of the bucket 20 in a small space, and solving the problem of large space occupation of the existing unloading device when unloading. Meanwhile, the overturning and dumping unloading mode of the bucket 20 avoids the problem of jamming or even tearing of the unloading device when unloading.

[0032] Specifically, as shown in Figures 3-5 The vertical sliding block 32 is provided with a first rotating shaft seat 41, the horizontal sliding block 34 is provided with a second rotating shaft seat 42, the bucket 20 is provided with a first rotating shaft hole and a second rotating shaft hole, one end of the first rotating shaft is fixedly connected to the first rotating shaft seat 41, the other end of the first rotating shaft penetrates through the first rotating shaft hole of the bucket 20, one end of the second rotating shaft is fixedly connected to the second rotating shaft seat 42, and the other end of the second rotating shaft penetrates through the rotating shaft hole of the bucket 20.

[0033] Optionally, the dumping mechanism further comprises a driving unit, the driving unit is arranged on the rack 10, and the driving unit can drive the vertical sliding block 32 to slide along the vertical guide rail 31. By arranging the driving unit to drive the vertical sliding block 32 to slide along the vertical guide rail 31, remote control can be realized, and the work burden of personnel is reduced. It should be noted that the positions at which the bucket 20 is rotationally connected to the vertical sliding block 32 and the horizontal sliding block 34, i.e., the connection positions of the first rotating shaft on the bucket 20 and the positions of the second rotating shaft on the bucket 20, can be designed according to the action of the bucket 20, and the rotationally connected positions determine the overturning angle of the bucket 20 and the driving stroke of the driving unit.

[0034] As shown in Figures 3-5As shown, in some embodiments of the present application, the driving unit is a motor 38 fixed on the frame 10; the pouring mechanism further comprises a chain transmission assembly, the chain transmission assembly comprising a driving sprocket 35, a driven sprocket 36 and a chain 37, the driving sprocket 35 and the driven sprocket 36 being drivingly connected through the chain 37, the driving sprocket 35 and the driven sprocket 36 being arranged along the vertical direction, the driving sprocket 35 and the driven sprocket 36 being rotatably arranged on the frame 10, one side of the chain 37 being connected with the vertical sliding block 32, and the output end of the motor 38 being connected with the driving sprocket 35 and capable of driving the driving sprocket 35 to rotate. Specifically, when the motor 38 drives the driving sprocket 35 to rotate, the chain 37 rotates synchronously with the driving sprocket 35, and the connecting point of the chain 37 and the vertical sliding block 32 is displaced in the vertical direction, thereby driving the vertical sliding block 32 to move along the vertical guide rail 31. By controlling the forward rotation or reverse rotation of the motor 38, the moving direction of the vertical sliding block 32 can be changed, so that the vertical sliding block 32 moves upward or downward. The pouring mechanism in the present application realizes the complex overturning and pouring action of the bucket 20 by using a single power source, has a simple structure, and is conducive to reducing the cost.

[0035] Of course, in other embodiments, the chain transmission assembly can be replaced by a belt transmission assembly. However, compared with the belt transmission mode, the chain transmission mode has no elastic sliding and slipping phenomenon, has an accurate average transmission ratio, is more reliable in work, has higher efficiency, and has smaller transmission size under the same working condition, so the chain transmission mode is preferred. Alternatively, the driving unit can also be a ball screw mechanism, an electric push rod, a hydraulic push rod, a linear motor, a hydraulic cylinder or an air cylinder, etc. The combination of the chain transmission assembly and the motor is preferred because the chain transmission mode has larger power transmission and stronger overload capacity, and can work in harsh environments such as high temperature, humidity, dust and pollution.

[0036] Specifically, when the chain transmission assembly is replaced by a belt transmission assembly, the belt transmission assembly comprises a driving wheel and a driven wheel, the driving wheel and the driven wheel being drivingly connected through a synchronous belt, the driving wheel and the driven wheel being arranged along the vertical direction, the driving wheel and the driven wheel being rotatably arranged on the frame, one side of the synchronous belt being connected with the vertical sliding block 32, and the motor being fixed on the frame, the output shaft of the motor being connected with the driving wheel and capable of driving the driving wheel to rotate. When the motor 38 drives the driving wheel to rotate, the synchronous belt rotates synchronously with the driving wheel, and the connecting point of the synchronous belt and the vertical sliding block 32 is displaced in the vertical direction, thereby driving the vertical sliding block 32 to move along the vertical guide rail 31.

[0037] When the driving unit is a ball screw mechanism, the ball screw mechanism comprises a motor and a screw, the output shaft of the motor being connected with the screw and capable of driving the driving wheel to rotate, a nut being sleeved on the screw and threadedly engaged with the nut, and the vertical sliding block 32 being connected with the nut. When the motor drives the screw to rotate, the nut will move along the screw, thereby driving the vertical sliding block 32 to move along the vertical guide rail 31.

[0038] When the driving unit is an electric push rod, a hydraulic push rod or a linear motor, the vertical sliding block 32 is connected to the push rod of the electric push rod, the hydraulic push rod or the linear motor, the push rod extends in the vertical direction, and the push rod retracts to drive the vertical sliding block 32 to move along the vertical guide rail 31.

[0039] When the driving unit is a hydraulic cylinder or a pneumatic cylinder, the vertical sliding block 32 is connected to the piston rod of the hydraulic cylinder or the pneumatic cylinder, the piston rod extends in the vertical direction, and the piston rod retracts to drive the vertical sliding block 32 to move along the vertical guide rail 31.

[0040] Optionally, the connection point of the cargo bucket 20 and the vertical sliding block 32 is located below the center of gravity of the cargo bucket 20. By setting the connection point of the cargo bucket 20 and the vertical sliding block 32 below the center of gravity of the cargo bucket 20, when the cargo bucket 20 is overturned and dumped to unload the objects in the cargo bucket 20, it can automatically dump to one side of the horizontal sliding block 34 or have this trend under the action of its own gravity, thereby saving a part of the driving force of the driving unit and being beneficial to prolong the service life of the driving unit.

[0041] In some embodiments of the present application, as shown in Figures 3-5 The opening edge of the cargo bucket 20 is provided with a ring of outwardly inclined guide plates 21, and the included angle α between the guide plates 21 and the outer wall surface of the cargo bucket 20 is obtuse. By setting the guide plates 21 with the above structure, the objects in the cargo bucket 20 can be accurately slid along the guide plates 21 to the target position from the opening of the cargo bucket 20 when the cargo bucket 20 is overturned and dumped. For example, when it is needed to pack the express items in the cargo bucket 20 into a packing bag, the express items in the cargo bucket 20 can be more accurately slid into the packing bag along the guide plates 21 from the opening of the cargo bucket 20 as the cargo bucket 20 is overturned and dumped.

[0042] Optionally, the number of the cargo buckets 20 can be one, two, three or more, and each cargo bucket 20 is matched with at least one dumping mechanism. The number of the dumping mechanisms can be set according to actual needs. For example, one dumping mechanism is arranged on each cargo bucket 20, and the dumping mechanism is arranged on the side of the cargo bucket 20. Alternatively, one dumping mechanism is arranged on each pair of opposite sides of each cargo bucket 20, and the two dumping mechanisms arranged on the opposite sides of the same cargo bucket 20 are symmetrically arranged, so that the cargo bucket 20 is more stable when it is turned over and dumped, and the shaking of the cargo bucket 20 when it is turned over and dumped is reduced or even avoided. Specifically, the cargo bucket 20 includes a first side and a second side arranged opposite to each other. One cargo bucket 20 can be matched with two dumping mechanisms, that is, one dumping mechanism is arranged on the first side of the cargo bucket 20, and one dumping mechanism is symmetrically arranged on the second side of the cargo bucket 20, and the two dumping mechanisms drive the cargo bucket 20 to be turned over and dumped. Alternatively, two cargo buckets 20 can be matched with two dumping mechanisms, that is, the second side of the first cargo bucket 20 and the first side of the second cargo bucket 20 are fixedly connected, one dumping mechanism is arranged on the first side of the first cargo bucket 20, and one dumping mechanism is symmetrically arranged on the second side of the second cargo bucket 20, and the two dumping mechanisms drive the two cargo buckets 20 to be turned over and dumped at the same time.

[0043] For example, as shown in Figure 1 and Figure 2 , four cargo buckets 20 are arranged on the rack 10. Each cargo bucket 20 includes a first side and a second side arranged opposite to the first side. One dumping mechanism can be arranged on the first side of each cargo bucket 20, and one dumping mechanism can be arranged on the second side of each cargo bucket 20. The dumping mechanism arranged on the first side of the same cargo bucket 20 is symmetrically arranged with the dumping mechanism arranged on the second side of the same cargo bucket 20, and the two dumping mechanisms drive the cargo bucket 20 to be turned over and dumped. Alternatively, the four cargo buckets 20 can be divided into two groups. In the same group of two cargo buckets 20, the second side of the first cargo bucket 20 is fixedly connected with the first side of the second cargo bucket 20, one dumping mechanism is arranged on the first side of the first cargo bucket 20, and one dumping mechanism is arranged on the second side of the second cargo bucket 20. The two dumping mechanisms arranged on the same group of cargo buckets 20 are symmetrically arranged, and the two dumping mechanisms drive the two cargo buckets 20 to be turned over and dumped at the same time.

[0044] In some embodiments, the rack 10 includes a base 11 and a plurality of mounting plates 12. The plurality of mounting plates 12 are arranged in a spaced manner along the length direction of the base 11. The cargo buckets 20 are located between adjacent two mounting plates 12, and the two dumping mechanisms arranged on the opposite sides of each cargo bucket 20 are correspondingly arranged on the adjacent two mounting plates 12. By arranging a plurality of mounting plates 12 in a spaced manner, a plurality of cargo buckets 20 can be arranged on one rack 10 at the same time, and the plurality of cargo buckets 20 can be turned over and dumped at the same time without interfering with each other, thereby improving the work efficiency.

[0045] It can be understood that the number of installation plates 12 can be two, three, four or more, which can be set according to actual needs. For example, as shown in Figures 1-2 The rack 10 includes three installation plates 12, which are arranged at intervals, and two barrels 20 are arranged between every two adjacent installation plates 12. One dumping mechanism can be symmetrically arranged on each of the two opposite sides of each barrel 20. The two dumping mechanisms on the two opposite sides of the same barrel 20 are arranged on the adjacent two installation plates 12 in a one-to-one correspondence. The two dumping mechanisms drive the barrel 20 to overturn and dump. Moreover, the overturning and dumping actions of the adjacent two barrels 20 do not interfere with each other. Alternatively, the two barrels 20 of the adjacent two installation plates 12 can be divided into a group. In the two barrels 20 of the same group, the second side of the first barrel 20 is fixedly connected with the first side of the second barrel 20. One dumping mechanism is arranged on the first side of the first barrel 20, and one dumping mechanism is arranged on the second side of the second barrel 20. The two dumping mechanisms on the same group of barrels 20 are symmetrically arranged. The two dumping mechanisms drive the two barrels 20 of the same group to overturn and dump at the same time.

[0046] The working principle of the unloading device provided in the embodiment of the present application is as follows: as shown in Figure 3 and Figure 4 The vertical guide rail 31 is arranged at an interval with the horizontal guide rail 33, and the midpoint of the vertical guide rail 31 is located on the extension line of the horizontal guide rail 33 in the horizontal direction. The initial position of the vertical sliding block 32 is at the bottom end of the vertical guide rail 31, and the initial position of the horizontal sliding block 34 is at the end of the horizontal guide rail 33 close to the vertical guide rail 31. When the vertical sliding block 32 is driven by a vertical upward driving force, the vertical sliding block 32 will move upward along the vertical guide rail 31, and the horizontal sliding block 34 will start to move along the horizontal guide rail 33 in a direction away from the vertical guide rail 31; as shown in Figure 5 When the vertical sliding block moves to the height of the horizontal guide rail 33, the horizontal sliding block 34 is located at the end of the horizontal guide rail 33 away from the vertical guide rail 31. At this time, the barrel 20 is in a horizontal dumping state. When the vertical sliding block continues to move upward along the vertical guide rail 31 under the action of the driving force, the horizontal sliding block 34 moves along the horizontal guide rail 33 in a direction close to the vertical guide rail 31. The barrel 20 is further dumped. As the inclination angle of the barrel 20 increases, the objects in the barrel 20 can slide out along the inner wall of the barrel 20, thereby achieving unloading. When the vertical sliding block 32 is at the top end of the vertical guide rail 31, the inclination angle of the barrel 20 is the largest. The unloading device provided in the embodiment of the present application realizes the overturning and dumping action of the barrel 20 in a very small space, thereby avoiding interference with other mechanisms.

[0047] The embodiment of the present application further provides a transportation system, as shown in Figures 1-2As shown, the transport system comprises the transport vehicle 50 and the unloading device as described in any of the above embodiments, and the rack 10 of the unloading device is mounted on the transport vehicle 50. The unloading device is moved together with the transport vehicle 50, so that a wide range of operation can be achieved. It should be noted that when the rack 10 of the unloading device comprises a plurality of mounting plates 12, and two barrels 20 are arranged between adjacent two mounting plates 12, the arrangement direction of the plurality of mounting plates 12 should be parallel to the advancing direction of the transport vehicle 50, so that the barrels 20 of the unloading device can unload the goods from both sides of the advancing direction of the transport vehicle 50, and the unloading work can be smoothly carried out.

[0048] The embodiment of the present application also provides a sorting and packing system, which comprises Figure 6 As shown, the sorting and packing system comprises the sorting device 60, the packing station 70, and the transport system as described in any of the above embodiments, and the transport system is used for reciprocating between the sorting device 60 and the packing station 70, so as to transport the goods sorted by the sorting device 60 to the packing station 70.

[0049] Optionally, the transport vehicle 50 is an automated guided vehicle (i.e., AGV, Automated Guided Vehicle), and the sorting and packing system further comprises a fixed guide rail 80, the length of the fixed guide rail 80 can be set according to actual needs, the automated guided vehicle can move along the fixed guide rail 80, and the sorting device 60 and the packing station 70 are distributed along the extension direction of the fixed guide rail 80. The combination of the automated guided vehicle and the fixed guide rail 80 has the advantages of stable driving and accurate positioning. Each transport vehicle 50 carries a plurality of barrels 20, which are used for transporting goods between the compartment 61 of the sorting device 60 and the packing station 70, and after completing the unloading, the transport vehicle 50 drives to the compartment 61 of the sorting device 60 again to receive goods, and the above process is repeated.

[0050] The sorting and packing system of the present application can be applied to the logistics industry to sort and pack express items. When the express items are sorted in the transfer field, the express items with small volume need to be concentrated and packed, that is, a plurality of express items with the same destination are packed together and sent to the destination. Since the target flow directions of different transfer fields are different, there are dozens to hundreds of target flow directions. In order to send the sorted express items to the concentrated packing station 70, the sorted express items are first loaded into the barrels 20, and then transported to the packing station 70 by the transport vehicle 50. The barrels 20 are overturned and dumped to unload the express items. After completing the unloading, the transport vehicle 50 drives to the compartment 61 of the sorting device 60 again to receive goods, and the above process is repeated. Preferably, the automated guided vehicle is used as the transport vehicle 50, so that the transportation of the sorted express items from the sorting device 60 to the packing station 70 can be more efficiently completed.

[0051] The prior art uses a conveying belt to unload the express items in the cargo bucket, and then uses a belt conveyor to load the express items into a packing bag. When the belt conveyor is conveying, the conveying efficiency cannot be precisely controlled due to the shape, size and weight of the express items, and the subsequent transport vehicle 50 often needs to queue at the packing station 70 to wait for unloading. The unloading device in the present application adopts a cargo bucket 20 overturning and dumping manner, which can directly unload the express items into the packing bag, and is not affected by the shape, size and weight of the express items, thereby achieving precise control of the conveying efficiency.

[0052] In the above embodiments, the description of each embodiment has its own focus, and the parts not described in detail in a certain embodiment can be referred to the relevant description of other embodiments.

[0053] In the description of the present application, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features.
