Description

Technical Field

[0001] The invention relates to an automatic container loading device used for centralized package transportation, belonging to the field of logistics sorting. Background Art

[0002] With the rapid development of domestic intelligent automation technology, various automated equipment used in sorting and transfer stations in the express delivery and e-commerce industries have also been rapidly popularized. Automated control processes have been applied from the initial sorting to the final sorting after the parcel is unloaded, and the entire sorting process of small parcels has been basically automated.

[0003] The common existing bulk cargo transportation method is to use a transport vehicle to load and transport a parcel to the same or similar destination. When loading the cargo parcel, the initial and final sorting processes need to be performed, and the code needs to be scanned piece by piece to enter the relevant information, and then the parcel is loaded piece by piece. When arriving at the destination, the unloading is still performed piece by piece, and the initial and final sorting processes are also required to scan the code and enter the information piece by piece. Performing the initial and final sorting processes twice in this way, both loading and unloading piece by piece, directly leads to the waste of production capacity of the sorting equipment in the transfer yard, and the investment in equipment and loading labor costs are both large. In order to solve this contradiction, the existing logistics sorting field has introduced the concept of container transportation, that is, the implementation of the containerization and transportation mode of express parcels. That is, the bulk parcels are loaded into different containers according to different destinations, and the containers of different destinations are transferred by vehicles. After arriving at the destination, the sorting operations such as scanning the code and entering information piece by piece are performed. Therefore, there is no need to sort the bulk goods, and the number of sorting destinations can be expanded in a more subdivided manner, which saves the investment in sorting equipment and labor in the transfer yard accordingly.

[0004] However, in the loading process of the logistics transfer yard, since the platform height is fixed and there are many types of transport vehicles and the height of the carriages are different, there is usually a certain height difference between the platform and the carriage docking surface, and transition equipment needs to be set up. At the same time, it is necessary to manually push the container loaded with cargo packages from the platform climbing or descending the slope into the carriage. The pushing process requires 2 to 3 people, especially during the descending process, it is necessary to focus on preventing the container from rushing into the carriage at too fast a speed and causing a collision accident. The above problems also exist in the unloading process.

[0005] The centralized loading method using containers adopted by the existing technology still requires a large number of on-site workers. Not only is the overall labor cost high and the labor intensity high, but there are also certain safety hazards. It is also not conducive to the layout of the transit yard logistics equipment and the improvement of the transfer efficiency.

[0031] In order to further explain the technical means adopted by the present application to achieve the predetermined design objectives, the following preferred implementation scheme is proposed in conjunction with the accompanying drawings.

[0032] In the following description, specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Embodiment 1, as Figure 1 to Figure 5-3 As shown, the present application proposes a new type of automatic container loading device, which is applied to the centralized loading operation of goods in the logistics transfer yard.

[0034] Loading small parcel cargo of the same or different destinations in each container 200;

[0035] After the transport vehicle stops at the loading station, the relative position of the lifting platform 300 and the cargo plane inside the carriage 100 is adjusted by the lifting platform 300 to achieve the same vertical height as the loading plane inside the carriage 100;

[0036] During the process of adjusting the vertical height of the lifting platform 300, the slope conveyor 400 connected to the lifting platform 300 rotates along with it, and the other end of the slope conveyor 400 is always connected to the platform 500;

[0037] The container 200 carrying the cargo package is transferred from the platform 500 to the carriage 100 through the slope conveyor 400 and the lifting platform 300 in sequence.

[0038] The above-mentioned slope conveyor 400 uses the connection point with the lifting platform 300 as a rotation fulcrum to form a climbing or downhill conveying channel, and the container 200 is manually transferred from the platform 500 to the slope conveyor 400;

[0039] The lifting platform 300 is overlapped at the tail end of the slope conveyor 400, and the docking position of the lifting platform 300 is adjusted according to the actual height of the carriage 100. The container 200 loaded with bulk packages is automatically transported into the carriage 100 without manual intervention and auxiliary pushing, thereby realizing automated loading operations and containerized transportation methods.

[0040] The automatic container loading device comprises a lifting platform 300 and a slope conveyor 400. One side of the slope conveyor 400 is overlapped with the lifting platform 300. The slope conveyor 400 rotates with the lifting and lowering of the lifting platform 300 to change its conveying angle with the overlap as a fulcrum.

[0041] The slope conveyor 400 comprises a fixed frame assembly 2 , on which a transmission assembly driven by a motor assembly 4 and inclined slideways 3 installed on both sides of the fixed frame assembly 2 are arranged.

[0042] Among them, the preferred transmission component of this embodiment is a chain conveyor component 1, which has two groups of chains 01 arranged in parallel, each group of chains 01 is wound in a closed loop between a driving sprocket component 07 and a driven sprocket component 019, and the driving sprocket component 07 is connected to the motor component 4 through a bearing seat 08. The motor sprocket 40 is sleeved on the same drive shaft 010;

[0043] Driven by the motor assembly 4 , the driving shaft 010 drives the active sprocket assemblies 07 on both sides to rotate synchronously and drive the chain 01 to run along the conveying plane of the fixed frame assembly 2 , thereby conveying the container 200 along the slope conveyor 400 .

[0044] In combination with the above-mentioned preferred chain conveying assembly 1, the corresponding structural design scheme for the fixed frame assembly 2 is that the fixed frame assembly 2 is assembled by welding the rectangular tube 05, the first chain guard 06 and the second chain guard 09 in the vertical direction, and arrays of support rods 013, protective nets 014, clamping plates 015 and pull rods 016, and pull rod fixing plates 017 are installed on both sides of the rectangular tube 05; the first chain guide rail 011 and the second chain guide rail 012 are respectively arranged vertically along the chain 01, so that the chain 01 always runs in the first chain guide rail 011 and the second chain guide rail 012 in an orderly manner;

[0045] The driven sprocket assembly 019 includes a driven sprocket 0012 which is sleeved on a driven sprocket shaft 0013 through a driven sprocket bearing 0027, wherein both ends of the driven sprocket shaft 0013 are arranged as flat structures, and the flat shaft ends are fixed in a semi-waist groove 0028 of the fixed frame assembly 2 (marked as 0028 in the figure).

[0046] The inclined slideway 3 is assembled by a curved auxiliary plate 020 and at least one group of straight auxiliary plates (including a first straight auxiliary plate 021 and a second straight auxiliary plate 022 in this embodiment) arranged longitudinally, and a transversely arranged reinforcing rectangular tube 025 through fasteners 027.

[0047] A bent support frame 023 is reinforced and connected at the bottom of the bent auxiliary plate 020, and a straight support frame 024 is reinforced and connected at the bottom of the straight auxiliary plates (ie, the first straight auxiliary plate 021 and the second straight auxiliary plate 022).

[0048] In order to further enhance the installation stability of the inclined section slide 3, a plurality of clamps 026 are respectively arranged at the bottom of the curved auxiliary plate 020 and the straight auxiliary plate (i.e., the first straight auxiliary plate 021 and the second straight auxiliary plate 022). Each clamp 026 is fastened together with the corresponding support rod 013 of the above-mentioned fixed frame assembly 2 through a fastener 027, so that the inclined section slide 3 is installed as a whole on the side of the fixed frame assembly 2.

[0049] An array of inclined push rod assemblies 02 and a fixed push rod assembly 03 are installed on the conveying assembly (such as the preferred chain conveying assembly 1 in this embodiment).

[0050] The oblique push rod assembly 02 includes an oblique push bottom fixed plate 003 installed on the transmission assembly, a rotating shaft 002 is set on the bottom fixed plate 003, and a rotatable oblique plate 001 is hinged to the rotating shaft 002.

[0051] The fixed push rod assembly 03 includes a bottom fixed plate 006 installed on the transmission assembly, and the bottom fixed plate 006 is fixedly connected to the baffle plate 004 upward through the side plate 005.

[0052] An end shaft welding seat assembly 018 is provided at the side end of the fixed frame assembly 2, that is, one end of the rectangular tube 05.

[0053] The end shaft welding seat assembly 018 includes a fixed shaft 0010, on which two sets of fixed plates 007 and bearings 009 are symmetrically sleeved, and each set of bearings 009 is axially installed on the outer side of the fixed plate 007 through a bearing seat 008 and a connecting bolt 0011.

[0054] The slope conveyor 400 is used to carry, limit, fix and transport the container 200, such as through the chain 01 in the transmission component, the motor component 4 drives the chain 01 to run in a closed loop between the active sprocket component 07 and the driven sprocket component 019, thereby providing transmission force for the container carried thereon.

[0055] When the container 200 reaches the slope conveyor 400 from the front platform 500, it first passes through the inclined push rod assembly 02 in the transmission assembly. The container 200 presses the inclined plate 001 to flip around the rotating shaft 002 to ensure the smooth passage of the container 200. The container 200 slides on the inclined section slide 3 through the rollers at its bottom until the container 200 arrives at the nearest fixed push rod assembly 03. The baffle 004 of the fixed push rod assembly 03 stably limits the pulling of the container 200.

[0056] Due to the prior design, the distance between the inclined push rod assembly 02 and the fixed push rod assembly 03 is not less than the maximum side length of the container 200; when the container 200 abuts against the fixed push rod assembly 03, it is out of contact with the inclined push rod assembly 02, and the inclined plate 001 is reversely reset and flipped around the rotation axis 002. If the container 200 is subjected to external force or vibration, the inclined plate 001 can reversely block the container 200 from the rear to ensure that the container 200 does not fall off the fixed frame assembly 2.

[0057] Along with the operation of the chain 01 of the conveying assembly, the container 200 is transported forward along the conveying surface formed by the fixed frame assembly 2 to the lifting platform at the rear end.

[0058] The lifting platform 300 includes a hydraulic lifting device 5, a platform 7 connected by the hydraulic lifting device 5 along the vertical direction, a push rod assembly 6 is arranged at the bottom of the platform 7, a front flap 8 and a rear flap 9 are respectively connected to the front and rear ends of the platform 7, and an array buffer assembly 10, a group of protective nets 11 and a group of detection photoelectrics 16 are arranged on both sides of the platform 7.

[0059] The bottom of the push rod frame 030 is installed on the top frame of the hydraulic lifting device 5, and the platform 7 is fixed on the top of the push rod frame 030.

[0060] When the container 200 enters the platform 7 via the slope conveyor 400 through the rear flap 9, the buffer devices 10 on both sides can buffer the containers 200 to prevent them from colliding with each other. In addition, the protective net 11 is also used for safety protection of the containers 200.

[0061] A detection photoelectric device 16 for detecting whether the container 200 is in place is installed on the protective net 11. When the container 200 reaches the platform 7, the detection photoelectric device 16 sends a signal to the PLC control system to trigger the push rod assembly 6 to start running.

[0062] The hydraulic lifting device 5 includes a set of top and bottom frames 028, two sets of support rods 0291 are hinged vertically between the top and bottom frames 028, the hydraulic cylinder 027-1 is driven and connected to one set of support rods 0291, and the two sets of support rods 0291 and the top and bottom frames 028 respectively form 8 hinge points 029.

[0063] The telescopic rod at the output end of the hydraulic cylinder 027-1 is moved to drive the top frame to rise and fall vertically to achieve a change in the height position of the platform 7 relative to the carriage 100.

[0064] The push rod assembly 6 includes a push rod frame 030, which is welded by channel steel, connecting plates and other components. At least one set of docking connecting plates 033 is installed at the front end of the push rod frame 030, and an arc-shaped positioning groove 0331 is arranged along the longitudinal direction of the docking connecting plates 033.

[0065] The push rod frame 030 is provided with a push plate 0023 driven by a hydraulic cylinder transmission assembly 034. The hydraulic cylinder transmission assembly 034 includes a hydraulic cylinder 0017 and a group of transmission chains 0018 driven by the hydraulic cylinder 0017. The transmission chain 0018 is wound between the sprocket 0019 and the counterweight end sprocket 0024. The end of the transmission chain 0018 is connected to the counterweight block 0026.

[0066] The output end of the hydraulic cylinder 0017 is connected to a transmission shaft, on which a sprocket 0019 and a guide wheel 0020 are coaxially sleeved. The guide wheel 0020 can slide inside the channel steel constituting the push rod frame 030 to reduce the resistance of the push plate 0023 when pushing the container 200 for transportation.

[0067] A push rod seat 0021 is fixed on the transmission chain 0018, and a push plate 0023 is hinged to the push rod seat 0021 through a push rod pin shaft 0022.

[0068] A front rotating shaft 031 and a rear rotating shaft 032 for hingedly connecting the front flap 8 and the rear flap 9 are fixed to the front and rear ends of the push rod frame 030 respectively.

[0069] A chain fixing plate 0014 , a hydraulic cylinder head fixing plate 0015 and a counterweight end sprocket fixing plate 0016 are arranged inside the push rod frame 030 .

[0070] Corresponding to the structural scheme of the above-mentioned fixed frame assembly 2, the hydraulic cylinder head connection hole 0025 at the fixed end of the hydraulic cylinder 0017 is installed on the hydraulic cylinder head fixing plate 0015 through a pin shaft;

[0071] The counterweight end sprocket 0024 is shaft-mounted on the counterweight end sprocket fixing plate 0016; the chain fixing plate 0014 is used to fix one end of the transmission chain 0018.

[0072] When the output end of the hydraulic cylinder 0017 pushes and pulls the transmission shaft, the sprocket 0019 and the guide wheel 0020 on the transmission shaft move forward and backward together to drive the transmission chain 0018 to run. When the container 200 initially enters the lifting platform 300, the push plate 0023 is pressed by it and changes from an inclined state to a horizontal state, and the container 200 then enters the upper part of the hydraulic cylinder transmission assembly 034. The push rod seat 0021 fixed on the transmission chain 0018 and the push plate 0023 jointly push the container 200 forward until the container is transported to the inside of the carriage 100.

[0073] Before the container 200 enters the lifting platform 300, the visual detection device 600 of the PLC control system detects the actual inner plane height of the carriage 100, and the detection result is transmitted back to the PLC control system to start the hydraulic cylinder 027-1 in the hydraulic lifting device 5, and accordingly adjusts the height of the platform 7 itself to be consistent with the internal height of the carriage 100, so as to facilitate the container 200 to enter the interior of the carriage 100.

[0074] In order to improve the accuracy of the overlap between the slope conveyor 400 and the lifting platform 300, the rear flap 9 is overlapped on the inclined slide 3 of the slope conveyor 400. At the same time, after the height of the platform 7 is adjusted, the bearing 009 of the end shaft welding seat assembly 018 is docked in the positioning groove 0331 of the docking connecting plate 033 at the front end of the push rod frame 030, thereby completing the accurate docking between the slope conveyor 400 and the lifting platform 300.

[0075] In order to improve the accuracy of docking between the lifting platform 300 and the carriage 100 , after the height of the platform 7 is adjusted, the front flap 8 is overlapped at the entrance of the carriage 100 .

[0076] In summary, the embodiments given in conjunction with the accompanying drawings are only preferred solutions. Those skilled in the art can be inspired by this and directly deduce other alternative structures that are consistent with the design concept of the present invention, which should also fall within the scope of the solution described in the present invention.
