Description

Technical Field

[0001] This utility model relates to the technical field of loading equipment, and more particularly to a loading system. Background Technology

[0002] In fertilizer, chemical, grain, food, and cement production enterprises, bagged goods need to be loaded into transport vehicles and stacked using appropriate methods to ensure stability during transport. Currently, the common method is to manually stack goods inside the vehicles, which requires a large workforce and is labor-intensive and inefficient.

[0003] Existing loading systems mostly use the entire loading head to descend outside the car body, and the existing loading systems only have one conveyor belt to transport materials. The packing path is long, the loading efficiency is low, and the energy consumption of the entire loading head descending is large. Utility Model Content

[0004] In view of this, the embodiments of this utility model provide a loading system, which aims to solve the problems of low loading efficiency and high energy consumption of existing loading systems.

[0005] An embodiment of this utility model provides a vehicle loading system, comprising:

[0006] A support platform, wherein the support platform is arranged in the front-to-back direction and includes two uprights arranged parallel to each other in the left-to-right direction;

[0007] A material conveying assembly is movably mounted on the support platform in the front-to-back direction. The material conveying assembly includes a horizontal moving conveying assembly, a tilting transition conveying assembly, a telescopic transition conveying assembly, and a material-to-be-picked conveyor roller assembly, which are connected sequentially from back to front and respectively mounted on two uprights. The two tilting transition conveying assemblies are gradually moved closer to each other and tilted from back to front. The two ends of the telescopic transition conveying assembly are respectively hinged to the tilting transition conveying assembly and the material-to-be-picked conveyor roller assembly. The material-to-be-picked conveyor roller assembly is movably mounted on the inner side of the two uprights and has a vertical moving stroke.

[0008] The main drive unit includes a frame and a walking drive assembly and a lifting drive assembly mounted on the frame, which are respectively used to drive the material conveying assembly to move in the forward and backward direction and to drive the material to be picked up conveying roller assembly to move in the up and down direction;

[0009] A package grabbing device is mounted on the frame. The package grabbing device includes at least one gripper structure and a package stacking drive device. Each gripper structure is movably mounted between two uprights. The package stacking drive device is used to drive the gripper structure to move in the vertical, horizontal, and forward / backward directions.

[0010] The walking drive assembly includes multiple rollers, at least two slide rails, a connecting shaft, a walking motor, a walking gear, and a walking rack. The slide rails are respectively disposed above the two uprights. The multiple rollers are spaced apart below the frame and the horizontal transfer conveyor assembly. The rollers roll on the slide rails. The walking racks are spaced apart on one side of the slide rails. The connecting shaft is rotatably mounted on the frame in the left-right direction, and the walking gears are mounted at both ends of the connecting shaft. The walking gears mesh with the walking racks. The walking motor drives the connecting shaft to rotate.

[0011] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: In the loading system of this utility model, by setting a walking drive component to drive the material conveying component to move forward and backward, and a lifting drive component to drive the material-to-be-picked conveyor roller assembly to move up and down, the material-to-be-picked conveyor roller assembly can always be kept at the highest point of the truck bed, greatly shortening the distance between the material and the truck bed when stacking. It can also adapt to various specifications of truck bed side panels, making it more adaptable to vehicles. The material-to-be-picked conveyor roller assembly can be lifted and lowered, allowing it to be adjusted to the closest position to the transport vehicle for different transport vehicles. This effectively reduces the stroke of the gripper structure, improves loading efficiency, and significantly reduces energy consumption simply by lifting and lowering the material-to-be-picked conveyor roller assembly.

[0012] Meanwhile, the bag-grabbing device is mounted on the frame. When the main drive unit moves the conveyor roller assembly to be picked up, the entire bag-grabbing device also enters the carriage, ensuring that the gripper structure moves left and right closer to the sideboard, achieving gapless loading with the carriage. The bag-grabbing device can also get as close as possible to the carriage floor, effectively reducing the height of the stacked bags and preventing damage during the stacking process.

[0031] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0032] Please refer to Figures 1-5 As shown in the figure, an embodiment of the present invention provides a loading system including a support platform 100, a material conveying assembly 300, a main drive unit 400, and a bag-grabbing device 200. The material conveying assembly 300 is used to convey materials, the main drive unit 400 is used to drive the material conveying assembly 300 to move, and the bag-grabbing device 200 is used to grab and place materials between the material conveying assembly 300 and the vehicle compartment.

[0033] The support platform 100 is arranged in the front-to-back direction and includes two parallel uprights 110 arranged at intervals in the left-to-right direction. Each time loading is required, the truck is parked between the two uprights 110. It is worth noting that the support platform 100 can be a frame structure, a wall structure, a base structure, etc., mainly used to provide height differences and installation positions for other loading components. No limitation is made here, and all support platforms 100 with the above-mentioned structures are within the scope of protection of this application.

[0034] The material conveying assembly 300 is movably mounted on the support platform 100 in the front-to-back direction. The material conveying assembly 300 includes a horizontal moving conveying assembly 310, a tilting transition conveying assembly 320, a telescopic transition conveying assembly 330, and a material-to-be-picked conveying roller assembly 340, which are connected sequentially from back to front and respectively mounted on the two uprights 110. The two tilting transition conveying assemblies 320 are gradually moved closer to each other and tilted from back to front. The two ends of the transition conveying assembly 330 are respectively hinged to the tilting transition conveying assembly 320 and the material-to-be-picked conveying roller assembly 340. The material-to-be-picked conveying roller assembly 340 is movably mounted on the inner side of the two uprights 110 and has a vertical moving stroke.

[0035] Here, the horizontal moving conveyor assembly 310 and the skew transition conveyor assembly 320 both use conveyor belts or roller conveyors, the material-to-be-picked conveyor roller assembly 340 uses a roller conveyor, and the telescopic transition conveyor assembly 330 uses a telescopic conveyor belt. Other combined structures can also be used. The main purpose is to realize the connection relationship between the material-to-be-picked conveyor roller assembly 340 and the skew transition conveyor assembly 320 when the material-to-be-picked conveyor roller assembly 340 moves up and down, so that the intermediate transition conveyor assembly can extend and retract synchronously with the material-to-be-picked conveyor roller assembly 340 when it moves up and down. The above-mentioned conveyor assemblies and telescopic conveyor belt 330 are all existing technologies, and the specific structure will not be described in detail here.

[0036] By setting two inclined transition conveyor components 320 that gradually approach each other from back to front, the telescopic transition conveyor component 330 and the material-receiving conveyor roller assembly 340 located at the front end are easily installed on the inner side of the two uprights 110. This provides room for the material-receiving conveyor roller assembly 340 to move vertically and horizontally, avoiding interference with the uprights 110. When the material-receiving conveyor roller assembly 340 moves vertically, the telescopic transition conveyor component 330, with its telescopic characteristics and hinged connection at both ends, can drive the telescopic conveyor belt 330 to move together. This ensures that the telescopic transition conveyor component 330 is evenly connected to the material-receiving conveyor roller assembly 340 throughout the process, thereby ensuring that materials can be continuously fed onto the material-receiving conveyor roller assembly 340.

[0037] Material is fed from both sides of the truck, and the material is conveyed to the middle of the truck bed through two skewed transition conveyor components 320, which reduces the travel distance of the material bag to the truck bed. The material is conveyed from both sides to the sides of the truck bed at the same time, which greatly improves the loading efficiency.

[0038] The main drive unit 400 includes a frame 410 and a walking drive assembly 420 and a lifting drive assembly 430 mounted on the frame 410, which are respectively used to drive the material conveying assembly 300 to move in the forward and backward direction and drive the material to be picked up conveying roller assembly 340 to move in the up and down direction.

[0039] The package grabbing device 200 is mounted on the frame 410. The package grabbing device 200 includes at least one gripper structure 8 and a package stacking drive device. Each gripper structure 8 is movably mounted between two uprights 110. The package stacking drive device is used to drive the gripper structure 8 to move in the up-down, left-right and forward-backward directions.

[0040] In this loading system, the walking drive component 420 drives the material conveying component 300 to move forward and backward, while the lifting drive component 430 drives the material-to-be-picked conveyor roller assembly 340 to move up and down. This ensures that the material-to-be-picked conveyor roller assembly 340 is always positioned at the height of the truck bed sideboard, significantly reducing the material retrieval height during stacking. It also adapts to various truck bed sideboard sizes, making it more versatile for different vehicles. The material-to-be-picked conveyor roller assembly 340 can be raised and lowered, allowing it to be adjusted to the position closest to the truck bed for different transport vehicles. This effectively reduces the stroke of the gripper structure 8, improving loading efficiency. Furthermore, the simple raising and lowering of the material-to-be-picked conveyor roller assembly 340 significantly reduces energy consumption.

[0041] Simultaneously, the bag-grabbing device 200 is mounted on the frame 410. When the main drive unit 400 drives the material-to-be-picked conveyor roller assembly 340 to move, the entire bag-grabbing device 200 also enters the carriage, ensuring that the gripper structure 8 moves left and right closer to the side panel, achieving gapless loading with the carriage. The bag-grabbing device 200 can also approach the carriage floor at its maximum, effectively reducing the height of the stacked bags and preventing damage to the bags during the stacking process.

[0042] Specifically, the frame 410 includes a mounting frame 411 located at the front end, the mounting frame 411 being parallel to each other on the inner sidewalls in the front-rear direction; the frame 410 also includes four movable frames 412, which are spaced apart in pairs on the inner sidewalls in the front-rear direction of the mounting frame 411, and the two material conveying roller assemblies 340 to be picked up are respectively fixed to the bottom ends of the two movable frames 412 located on the same side.

[0043] Reference Figure 6As shown, the lifting drive assembly 430 includes four lifting groups, each corresponding to one of the four movable frames 412. Each lifting group includes a slide rail assembly 431, a rack 432, a rotating shaft 433, a gear 434, and a motor 435. The slide rail assembly 431 includes a slidingly connected slide rail and a slider. The slide rail is fixed to the movable frame 412, and the slider is fixed to the inner wall of the mounting frame 411. The rack 432 extends vertically and is fixed to the movable frame 412. The rotating shaft 433 extends horizontally, with both ends rotatably mounted on the inner wall of the mounting frame 411. The gear 434 is fixed to the rotating shaft 433 and meshes with the rack 432. The motor 435 is fixed to the inner wall of the mounting frame 411 and connected to one end of the rotating shaft 433.

[0044] The motor 435 drives the gear 434 to rotate on the rack 432, thereby causing the slide rail 2 on the moving frame 412 to slide up and down on the slider 2 on the moving plate 431, thereby causing the material conveying roller assembly 340 below to move up and down.

[0045] Here, the lifting units located at both ends of the material-to-be-picked conveyor roller assembly 340 are driven simultaneously to ensure that both ends of the material-to-be-picked conveyor roller assembly 340 remain in a horizontal state at all times.

[0046] In this structure, the material-carrying conveyor roller assembly 340 is raised and lowered independently, thus adapting to different vehicle models. This ensures that during packing, the material-carrying conveyor roller assembly 340 is always positioned close to the height of the vehicle side panel, thereby minimizing the stroke of the gripper structure 8 when grabbing materials. Compared to the existing technology where the entire main unit is raised and lowered together, this structure independently raises and lowers the material-carrying conveyor roller assembly 340, significantly reducing energy consumption.

[0047] In this embodiment, refer to Figure 5As shown, the walking drive assembly 420 includes multiple rollers 421, at least two slide rails, a connecting shaft 422, a walking motor 423, a walking gear 424, and a walking rack 425. The slide rails are respectively disposed above the two uprights 110. The multiple rollers 421 are spaced apart below the frame 410 and the horizontal transfer conveying assembly. The rollers 421 roll on the slide rails. The walking racks 425 are spaced apart on one side of the slide rails. The connecting shaft 422 is rotatably disposed on the frame 410 in the left-right direction, and the walking gears 424 are installed at both ends of the connecting shaft 422. The walking gears 424 mesh with the walking racks 425. The walking motor 423 drives the connecting shaft 422 to rotate. The walking drive assembly 420 works similarly to the lifting assembly. It is driven by the walking motor 423 to rotate the walking gear 424 on the walking rack 425, thereby causing the pulley to slide on the slide rail. The walking rack 425 is located next to the walking slide rail. Both the walking gear 424 and the walking motor 423 are fixed on the frame 410. This drive structure is relatively conventional. The walking motor 423 and the walking gear 424 can also be transmitted through a chain structure. However, the innovation of this application does not lie in this, so it will not be described in detail here.

[0048] In other embodiments, the above-mentioned drive structure is not limited to a gear and rack structure; a chain drive or other structure can also be used, as long as it satisfies the movement functions such as lifting and walking.

[0049] Furthermore, the bag-grabbing device 200 includes two gripper structures 8, which are spaced apart in the left-right or front-back direction, and the distance between the two gripper structures 8 is adjustable.

[0050] Two gripper structures 8 are simultaneously installed, which can pick up materials from the material conveying roller assemblies 340 on both sides, improving the efficiency of bagging. The spacing between the two gripper structures 8 is adjustable, which can be used for various sizes of bags and transport vehicles. It can also ensure that the gripper structures 8 can move laterally to approach the side panel, achieving gapless loading with the vehicle body.

[0051] Furthermore, the bag-grabbing device 200 includes four gripper structures 8, which are arranged in pairs along the left-right and front-back directions, and the spacing between each pair of gripper structures 8 is adjustable.

[0052] By setting up four gripper structures 8 in two columns and two rows with adjustable spacing, the efficiency of packing can be further improved. At the same time, the packing spacing can be adjusted according to different specifications of packs, making it highly adaptable.

[0053] The above are only two preferred embodiments. In actual use, more than 6, 8 or other gripper structures 8 can be set as needed, distributed in multiple rows and columns, so that multiple gripper structures 8 can capture and encode packets at the same time, thereby improving packet encoding efficiency.

[0054] Reference Figures 12-14 As shown, each gripper structure 8 includes a mounting plate 81, two mounting brackets 83, a horizontal drive device 84, two gripping rod assemblies 85, and two rotating devices 86. The mounting plate 81 is rotatably mounted on the package drive device via a rotating mechanism 82; the two mounting brackets 83 are movably disposed horizontally below the mounting plate 81, and the two mounting brackets 83 have a travel distance that allows them to move closer or further apart; the horizontal drive device 84 is installed between the mounting plate 81 and the mounting brackets 83, and is used to drive the two mounting brackets 83 to move closer or further apart; the two gripping rod assemblies 85 have mounting portions 851 near their rear ends, and the two mounting portions 851 are rotatably disposed at the lower ends of the two mounting brackets 83, so that the front ends of the two gripping rod assemblies 85 have a closed state where they are close to each other and coplanar horizontally, and an open state where they are far apart and vertically parallel; the two rotating devices 86 are respectively connected to the two gripping rod assemblies 85, and are used to drive the gripping rod assemblies 85 to rotate.

[0055] The gripping device 200 uses a horizontal drive device 84 in the gripper structure 8 to drive the two mounting frames 83 to move closer or further apart, thereby making the distance between the gripping rod assemblies 85 mounted on the two mounting frames 83 adjustable. This allows it to adapt to the size of the material at any time, enabling the gripper structure 8 to grip materials of different sizes.

[0056] Secondly, by installing the gripper structure 8 on the stacking drive device, the gripper structure 8 can move vertically, horizontally, and vertically. This allows the gripper structure 8 to grab the material bag and load it sequentially along the length, width, and height of the truck bed. Furthermore, the size of the gripper structure 8 can be adjusted at any time according to loading requirements to accommodate materials of different specifications, resulting in high loading efficiency.

[0057] In this embodiment, please refer to the specific details. Figure 7-11 As shown, the packet driving device includes at least one driving group, which is arranged one-to-one with the gripper structure 8. Each driving group includes a first slide rail assembly 2, a second slide rail assembly 5, and a fourth slide rail assembly 33 that are perpendicularly connected to each other, respectively used to drive the gripper structure 8 to move in the left-right, up-down, and forward-backward directions. The driving group includes the first slide rail assembly 2, the fixing plate 4, the second slide rail assembly 5, the horizontal driving assembly 6, and the vertical driving assembly 7.

[0058] The first slide rail assembly 2 includes a fixed plate 4, a horizontal drive assembly 6, two first slide rails 21, and at least two first sliders 22. The two first slide rails 21 are arranged in parallel and spaced apart. The two ends of the first slide rails 21 are slidably disposed on the left and right side walls of the mounting frame 411. The two first sliders 22 are respectively slidably disposed on the two first slide rails 21. The two ends of the fixed plate 4 are respectively fixed on the two first sliders 22. The middle part of the fixed plate 4 is provided with a sliding hole. The second slide rail assembly 5 extends vertically and is disposed in the sliding hole, so that the second slide rail assembly 5 can move between the two first slide rails 21. This structure is more stable. The horizontal drive assembly 6 is used to drive the first sliders 22 to move on the first slide rails 21.

[0059] The second slide rail assembly 5 includes a vertical drive assembly 7, a fixed rod 53, a second slide rail 51, and a second slider 52. The second slide rail 51 is fixed to the side wall of the fixed rod 53, and the lower end of the fixed rod 53 is provided with a mounting groove 531. The vertical drive assembly 7 drives the second slider 52 to move on the second slide rail 51. The rotating mechanism 82 includes a servo motor 821 and a reducer 822. The servo motor 821 is installed in the mounting groove 531, and the reducer 822 is connected to the mounting plate 81. The output shaft of the servo motor 821 is connected to the reducer 822.

[0060] The servo motor 821 and reducer 822 are set below the fixed rod 53 to directly drive the gripper structure 8 to rotate. The structure is simple and has high rotation efficiency. It can rotate when the second slide rail assembly 5 moves up and down, and the two movements do not interfere with each other, thus improving efficiency.

[0061] The horizontal drive assembly 6 includes a first rack 61, a first gear 62, and a first motor 63. The first rack 61 is disposed on the outside of the first slide rail assembly 2; the first gear 62 meshes with the first rack 61; the first motor 63 is fixed on the fixing plate 4, and the main shaft of the first motor 63 extends downward and is coaxially connected to the first gear 62.

[0062] The first motor 63 drives the first gear 62 to rotate, thereby causing the fixed plate 4 to move along the first rack 61, which in turn causes the first slider 22 to slide on the first slide rail 21, that is, the second slide rail assembly 5 moves along the extension direction of the first slide rail assembly 2.

[0063] Similarly, the vertical drive assembly 7 includes a second rack 71, a second gear 72, and a second motor 73. The second rack 71 is disposed on the outside of the second slide rail assembly 5; the second gear 72 meshes with the second rack 71; the second motor 73 is fixed on the fixed plate 4, and the main shaft end of the second motor 73 is coaxially connected to the second gear 72.

[0064] The fourth slide rail assembly 33 includes a translation drive assembly 3, at least one drive shaft 31, at least two connecting plates 32, at least two fourth slide rails 331 and fourth sliders 332, at least two third racks 34, at least two third gears 35, and a third motor 36. The drive shaft 31 is rotatably mounted on one side wall of one of the first slide rails 21; the two connecting plates 32 are respectively fixed to the lower ends of the two first slide rails 21, and one side of each connecting plate 32 has a through groove 321; the two fourth slide rails 331 are respectively located on the left and right sides of the mounting frame 411, and the fourth sliders 332 are fixed below the connecting plates 32; the two third racks 34 are respectively spaced apart on one side of each of the two fourth slide rails 331; the two third gears 35 are fixed to both ends of the drive shaft 31 and located within the through grooves 321, and the third gears 35 mesh with the corresponding third racks 34; the third motor 36 is fixed to the connecting plate 32, and the output end of the third motor 36 is connected to the drive shaft 31 to drive the drive shaft 31 to rotate.

[0065] The transmission shaft 31 is driven to rotate by the third motor 36, which in turn drives the two third gears 35 to rotate synchronously, thereby causing the first slide rail 21 on the connecting plate 32 to move along the direction of the third rack 34.

[0066] It is worth noting that the slide rail assembly 431, the first slide rail assembly 2, the second slide rail assembly 5 and the third slide rail assembly 841 involved in this application are all common linear drive assemblies, and all include slide rails and sliders that are slidably connected. This technology is prior art and will not be described in detail here.

[0067] Specifically, the mounting bracket 83 includes a horizontal plate 831 and a vertical plate 832 connected vertically. The horizontal plate 831 is installed above the vertical plate 832, and the two mounting brackets 83 are arranged opposite to each other so that an installation space is formed between the two mounting brackets 83.

[0068] By installing the rotating device 86 within the installation space formed by the two mounting brackets 83, the structure can be made more compact, and the entire gripper structure is the size of the material bag specification.

[0069] The rotating device 86 is installed within the installation space. The rotating device 86 includes a telescopic actuator 861, a first connecting rod 862, and a second connecting rod 863. The telescopic actuator 861 includes a fixed end and a movable end that are slidably connected. The fixed end is hinged to the lower end surface of the horizontal plate 831. The upper end of the first connecting rod 862 is hinged to the lower end surface of the horizontal plate 831, and the middle part is hinged to the movable end. The two ends of the second connecting rod 863 are respectively hinged to the lower end of the first connecting rod 862 and the rear end of the gripping rod assembly 85.

[0070] Here, the rotating device 86, the gripping rod assembly 85, and the mounting frame 83 together form a six-bar linkage. The telescopic actuator 8618 can be a cylinder or an electric push rod. The telescopic actuator 8611 drives the first link 862 and the second link 863 to rotate, thereby driving the end gripping rod assembly 85 to rotate between a horizontal and a vertical state. This allows the two gripping rod assemblies 85 to switch between a closed and an open state, thus gripping and releasing the material bag. This six-bar linkage has a simple structure, good force distribution, and a large opening range.

[0071] The rotating device 86 is only a preferred embodiment. Other structures, such as motor drive, can also be used to drive the gripper group 85 to rotate, but these will not be elaborated on here.

[0072] Preferably, refer to Figure 12 and 13 As shown, the horizontal drive device 84 includes a third slide rail assembly 841, a twin screw 842, and a drive motor 844. The third slide rail assembly 841 includes a third slide rail 8411 and at least two third sliders 8412. The third slide rail 8411 is fixed below the mounting plate 81. One end of each of the two third sliders 8412 is slidably mounted on the third slide rail 8411, and the other ends of each third slider 8412 are respectively fixedly connected to two mounting brackets 83. The twin screw 842 is spaced apart on one side of the third slide rail 8411 and rotatably connected to the mounting plate 81. Two threaded blocks 843 are threadedly connected to the twin screw 842, and the two threaded blocks 843 are respectively fixedly connected to the two third sliders 8412. The drive motor 844 is fixed to the mounting plate 81, and the output shaft of the drive motor 844 is coaxially connected to one end of the twin screw 842.

[0073] The twin screw 842 has two threads with opposite directions of rotation at both ends. The twin screw 842 is driven to rotate by the drive motor 844, so that the two threaded blocks 843 at both ends move in opposite directions in a straight line. This causes the mounting brackets 83 fixed on the two threaded blocks 843 to move away from or closer to each other, thereby adjusting the distance between the two gripping rod assemblies 85 to adapt to materials of different specifications.

[0074] Furthermore, referring to Figure 15 and Figure 16 As shown, the gripping rod assembly 85 includes a hinge plate 852 and a plurality of gripping rods 853. The plurality of gripping rods 853 are detachably arranged at intervals along the length direction of the hinge plate 852, and the gripping rods 853 extend to one side of the hinge plate 852. The mounting part 851 is provided on the hinge plate 852.

[0075] By detachably connecting multiple gripping rods 853 along the length of the hinge plate 852, the length dimension of the gripping rod assembly 85 can be adjusted by controlling the number of gripping rods 853, thereby adapting to changes in material length. Changes in material width can be adapted by controlling the distance between two gripping rod assemblies 85.

[0076] The material conveying roller assembly 340 is a roller conveyor, comprising multiple spaced and self-rotating rollers. The distance between two adjacent gripping rods 853 is adapted to the distance between two adjacent rollers, so that when the gripping rod group 85 is in the open state, the gripping rod 853 is exactly located in the gap between the two adjacent rollers.

[0077] Specifically, a plurality of sleeves 854 are spaced apart below the hinge plate 852, and a plurality of gripping rods 853 are inserted one-to-one into the sleeves 854 and are interference-fitted with the sleeves 854. The number of gripping rods 853 can be determined according to the specifications of the material bag, and they are directly inserted into the sleeves 854, making installation simple.

[0078] In this document, the directional terms such as front, back, top, and bottom are defined based on the location of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed in this application.
