Description

Technical Field

[0001] This application relates to the technical field of logistics sorting, and particularly to an express delivery transportation component and a transportation system. Background Art

[0002] With the rise of various shopping festivals, the express delivery volume will increase significantly within a specific period, easily reaching the processing limit of the sorting station. This situation is particularly obvious in sorting stations in remote areas because their processing capacity is usually fully occupied only during peak periods and far from reaching the limit at other times. If the sorting line is expanded to cope with these short peak periods, it will not only increase the investment cost of the sorting station but also cause the sorting resources to be idle for most of the time. Summary of the Invention

[0003] The purpose of this application is to provide an express delivery transportation component and a transportation system to alleviate the temporary increase in the volume of goods and improve the sorting efficiency.

[0004] In a first aspect, this application provides an express delivery transportation component, adopting the following technical solution: It includes a vehicle body, a lifting platform installed on the vehicle body, and a transportation component installed on the vehicle body. The transportation component is located between the lifting platform and the transportation component. The lifting platform is provided with a plurality of through slots, and the transportation component can penetrate through the through slots; When the lifting platform is lifted to the highest position, the top surface of the lifting platform is the first placement area, and the area between the lifting platform and the vehicle body is the second placement area; When the lifting platform descends to the lowest position, the transportation component penetrates through the through slots, and the transportation plane of the transportation component is higher than the top surface of the lifting platform.

[0005] By adopting the above technical solution, during peak periods, after the lifting platform is lifted, the upper and lower layers of space can be used simultaneously to store packages, increasing the single - transport volume and alleviating the sorting pressure; in peak mode, the lifting platform is lifted for double - layer storage to increase the capacity; in off - peak mode, the lifting platform descends, and direct sorting and transportation can be carried out, reducing the operation steps and improving the efficiency. Through lifting adjustment, the limitation of the single - layer space of traditional express delivery transportation components is avoided, adapting to different flow requirements; the transportation component can penetrate through the through slots when the lifting platform descends, and its transportation plane is higher than the top surface of the lifting platform. After the lifting platform descends, the transportation component automatically "takes over" the packages and enters the transportation state without manual intervention, reducing the stagnation time; compared with expanding the sorting line, this solution only requires the transformation of the express delivery transportation component without significantly increasing fixed equipment, saving costs.

[0006] Preferably, the vehicle body includes a plurality of vertical side plates, a plurality of horizontal cross - plates, support rods, connection components, and a base provided with rollers. The side plates are connected to each other by support rods, the cross - plates are installed on the side plates through connection components, and the side plates are installed on the base through connection components.

[0007] By adopting the above technical solutions, the vehicle body is assembled by vertical side plates and horizontal cross plates through standardized connection components. The modular design enables the express transportation components to be assembled within 1 - 2 hours. The standardized components reduce the production cost per unit, saving more than 60% of the equipment investment compared with the fixed sorting line. The damaged parts can be replaced individually, and the maintenance time is shortened by 70%.

[0008] Preferably, the transportation component includes a power shaft rotatably connected to the side plate, a plurality of pulleys fixedly connected to the power shaft, a conveyor belt installed on the pulleys, and a first power source for driving the rotation of the power shaft. There are a plurality of steps on the cross plate, and the steps can pass through the through slots. The power shaft is installed at both ends of the steps, and the conveyor belt can rotate around the steps.

[0009] By adopting the above technical solutions, a step structure that can pass through the through slot is provided on the cross plate, so that the transportation plane of the conveyor belt installed on the steps can be higher than the top surface of the lifting platform. When the lifting platform descends to the lowest end, the goods placed on the lifting platform can be received on the conveyor belt, enabling the goods on the conveyor belt to be put into different delivery bins. In this way, whether in the off-peak mode or the peak mode, the same transportation components can be provided for the delivery of goods, reducing the introduction of power sources, not only saving costs but also reducing the overall size.

[0010] Preferably, an extension plate is fixedly connected to the vehicle body, and a plurality of optical rods and a plurality of lead screws are fixedly connected to the lifting platform. Both the optical rods and the lead screws penetrate through the extension plate. A rotating wheel is rotatably connected to the extension plate, and the rotating wheel is threadedly connected to the lead screw. The extension plate is provided with a second power source for driving the rotation of the rotating wheel.

[0011] By adopting the above technical solutions, the second power source drives the rotating wheel, enabling the lead screw to lift. The cooperation between the optical rod and the lead screw can ensure the stable ascent of the lifting platform. The extension plate prevents the optical rod and the lead screw from deviating from the vehicle body and prevents interference between the optical rod and the lead screw during the lifting process.

[0012] Preferably, a plurality of first grooves arranged in an array are provided on the top surface of the lifting platform. The first grooves are located on both sides of the through slot. A rotating column is rotatably connected in the first groove, and the direction of rotation of the rotating column is towards the center of the lifting platform. At least a part of the rotating column is higher than the top surface of the lifting platform.

[0013] By adopting the above technical solution, when the lifting platform is lowered to the lowest position, the rotating column is at least partially higher than the top surface of the lifting platform and lower than the transportation plane of the conveyor belt. When the goods are placed above the lifting platform, most parts of the goods will abut against the conveyor belt; during the rising process of the lifting platform, most parts of the goods gradually abut against the rotating column. During the upward movement of the lifting platform, the rotating column also rotates unidirectionally towards the central position of the lifting platform, so that the goods placed on the lifting platform can be moved to the central position, making the express transportation component more stable when transporting goods.

[0014] Preferably, a driving roller is rotatably connected in the first groove, the driving roller abuts against the rotating column, a driving shaft is rotatably connected in the lifting platform, the driving shaft is connected to the driving roller through gears, a first rotating shaft is rotatably connected in one of the optical shafts, the first rotating shaft is gear-connected to the driving shaft, an installation frame is fixedly connected to the end of the optical shaft, a second rotating shaft is rotatably connected to the installation frame, the first rotating shaft is gear-connected to the second rotating shaft, a gear disk is installed on the second rotating shaft, a rack is fixedly connected to the vehicle body, and the rack meshes with the gear disk.

[0015] By adopting the above technical solution, during the upward movement of the lifting platform, the lead screw and the optical rod move upward, and a relative movement is generated between the optical rod and the vehicle body. A rack is fixedly connected to the vehicle body, and a gear is installed at the end of the optical rod. This is the power source that converts the relative movement between the optical rod and the vehicle body into the rotation of the rotating column; the rotating column is driven through the driving shaft, the second rotating shaft, and gear transmission, so that no additional power source is required, greatly reducing the size of this device.

[0016] Preferably, the gear disk is provided with a pawl, the second rotating shaft is provided with ratchet teeth, the pawl is connected to the gear disk through a first spring, and under the action of the first spring, the pawl meshes with the ratchet teeth.

[0017] By adopting the above technical solution, through the cooperation of the pawl and the ratchet teeth, the gears can rotate unidirectionally, so that the rotating column can be driven towards the central position of the rotating platform during the rising process of the lifting platform; when the lifting platform descends, the pawl and the ratchet teeth disengage, and the rotating column stops rotating, thus realizing that the goods can only move towards the central position of the lifting platform during the rising process.

[0018] Preferably, a plurality of second grooves are provided at the top of the vehicle body, the second grooves and the conveyor belt are arranged at intervals in sequence, the projection of the first groove in the vertical direction is located inside the projection of the second groove in the vertical direction, a lifting block is provided in the second groove, a return spring is provided between the lifting block and the second groove, the return spring forces the lifting block to move upward, and the lifting block is at least partially higher than the top end of the vehicle body.

[0019] By adopting the above technical solution, the height difference between the conveyor belt transportation plane and the top of the vehicle body is reduced; when the lifting platform descends to the lowest position, the lifting platform presses the lifting block into the second groove; when the lifting platform ascends, the lifting platform extends under the action of the reset spring, compensating for the height difference between the conveyor belt transportation plane and the vehicle body.

[0020] In a second aspect, the present application provides a transportation system, adopting the following technical solution: including an express delivery transportation component, a number of cycloidal components, a central processing unit, a number of delivery bins, and a number of detection components. The express delivery transportation components are connected in series in sequence to form a cyclic sorting line. The detection components are respectively installed on the moving path of the express delivery transportation component and the bottom end of the lifting platform. The delivery bins are sequentially marked with serial numbers along the moving direction of the express delivery transportation component. The specific method is as follows: The serially connected express delivery transportation components are numbered in sequence and information QR codes are pasted. The central processing unit monitors the loading situation of each express delivery transportation component in real time through the detection components; the sorting component first places goods on the lifting platform of the express delivery transportation component. When there are goods placed on the lifting platform, the lifting platform moves upward, forming a new loading space between the lifting platform and the vehicle body. The remaining sorting components place the goods between the lifting platform and the vehicle body. The serial number of the delivery bin into which the goods located below are put is less than the serial number of the delivery bin into which the goods located above are put; the goods corresponding to the express delivery transportation component are sequentially put into the corresponding delivery bins and enter the next transportation.

[0021] By adopting the above technical solution, a double-layer three-dimensional sorting design is adopted. Through the intelligent adjustment of the lifting platform, the double utilization of the vertical space is realized, and the sorting capacity per unit area is increased by more than 80%; the cyclic sorting line is combined with the QR code tracking technology to realize the real-time monitoring and intelligent scheduling of each trolley, improving the sorting accuracy; compared with the traditional flat sorting line, the processing capacity of this system is increased by several times under the same site conditions, which is especially suitable for meeting the sorting requirements during peak business periods such as e-commerce promotions, and at the same time avoids the problem of resource idleness of the fixed sorting line during non-peak periods.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Improvement of dynamic space utilization rate and sorting efficiency. Through the intelligent adjustment of the lifting platform, the express delivery transportation component can form a double-layer loading space during peak periods, and the single transportation volume is increased by 100%, effectively alleviating the pressure during peak business periods; when switching to the single-layer mode during off-peak periods, the transportation component automatically passes through the through groove to take over the package, realizing seamless connection. With the self-centering design of the rotating column, the compensation structure of the lifting block, and the non-powered driven goods centering system, the transportation stability is ensured; 2. Flexible Adaptation and System-level Collaborative Innovation. The transportation system monitors the load status in real time through the detection components, intelligently allocates the matching relationship between the upper and lower layer goods and the delivery bins, and supports the dynamic sorting logic of "lower layer first delivery". When congestion is detected on a certain line, the central processor can automatically adjust the running speed of the trolley or temporarily activate the standby lifting channel.

[0025] The following is a further detailed description of the present application in conjunction with the Figure 1 - attached Figure 9 to further illustrate the present application in detail.

[0026] An embodiment of the present application discloses an express transportation component.

[0027] Example 1, referring to Figure 1 and Figure 2 , a courier transportation component includes a vehicle body 1, a lifting platform 2 installed on the vehicle body 1, and a transportation component 3. When the lifting platform 2 rises to the highest position, the transportation component 3 is located between the lifting platform 2 and the vehicle body 1; when the lifting platform 2 descends to the lowest position, the transportation component 3 can pass through the lifting platform; the lifting platform 2 is provided with a plurality of through grooves 21 communicating the upper and lower surfaces, and the transportation part of the transportation component 3 can pass through the through grooves 21. When the lifting platform 2 descends to the lowest position, the top surface of the lifting platform 2 is the area for storing goods; when the lifting platform 2 rises to the highest position, the top surface of the lifting platform 2 and the area between the lifting platform 2 and the transportation component 3 are the storage areas for goods. The transportation component 3 can penetrate through the through grooves 21 when the lifting platform 2 descends, and make its transportation plane higher than the top surface of the lifting platform 2. After the lifting platform 2 descends, the transportation component 3 automatically "takes over" the package and enters the transportation state without manual intervention, reducing the stagnation time; compared with expanding the sorting line, this solution only needs to transform the courier transportation component without significantly increasing fixed equipment, saving costs, and enabling a single transportation to transport goods in two storage areas.

[0028] Reference Figure 3 , the vehicle body 1 includes two vertical side plates 12, a horizontal cross plate 15, support rods, connection components, and a base 11 provided with rollers. The support rods connect the two side plates 12, and the side plates 12 and the cross plate 15, the side plates 12 and the base 11, and the support rods and the side plates 12 are connected to each other through the connection components. The connection components in Example 1 include common connection parts such as bolts and screws.

[0029] Reference Figure 2 and Figure 4 , the transportation component 3 includes a power shaft 32 rotatably connected to the side plate 12, a plurality of belt pulleys 31 fixedly connected to the power shaft 32, a conveyor belt 34 installed on the belt pulleys 31, and a first power source 14 for driving the power shaft 32 to rotate. A step 33 is provided on the top surface of the cross plate 15, and the step 33 is higher than the top surface of the cross plate 15. The power shaft 32 penetrates through the cross plate 15, and the belt pulleys 31 are distributed at both ends of the step 33. The conveyor belt 34 can surround the step 33, and the conveyor belt 34 abuts against the top end of the step 33. When the lifting platform 2 descends to the lowest position, the step 33 can pass through the through groove 21, so that the conveyor belt 34 can receive and transport the goods on the lifting platform 2. In Example 1, the first power source 14 adopts a motor and is connected to the power shaft 32 through a belt drive.

[0030] Reference Figure 1 , Figure 2 and Figure 5, on both sides of the vehicle body 1 perpendicular to the transport direction of the conveyor belt 34, there are fixedly connected extension plates 13. At the bottom end of the lifting platform 2, there are fixedly connected two optical rods 23 and two lead screws 22. The optical rods 23 and the lead screws 22 are both slidably connected to the extension plates 13. The extension plates 13 are rotatably connected with rotating wheels 241. The rotating wheels 241 are threadedly connected to the lead screws 22. The extension plates 13 are provided with a second power source 24. The second power source 24 uses a motor. A plurality of rotating wheels 241 and the second power source 24 are connected by a belt drive method. The extension plates 13 prevent the optical rods 23 and the lead screws 22 from deviating from the internal structure of the vehicle body 1 and prevent the optical rods 23 and the lead screws 22 from interfering during the lifting process.

[0031] Reference Figure 5 and Figure 6 , on the top surface of the lifting platform 2, there are several first grooves 25 arranged in an array. The first grooves 25 are located on both sides of the through groove 21. In the first grooves 25, there are rotatably connected rotating columns 251. The rotating columns 251 can rotate towards the center position of the lifting platform 2. The rotating columns 251 protrude from the top surface of the lifting platform 2. When the lifting platform 2 is at the lowest end, the top surface of the step 33 is higher than the rotating columns 251. When the lifting platform 2 is at the lowest end, at this time, most of the goods will be placed on the conveyor belt 34. When the second power source 24 is started to make the lifting platform 2 move upward, the goods rise from the conveyor belt 34 to the lifting platform 2, and the goods are lifted by the lifting platform 2. At this time, a new storage area is formed between the lifting platform 2 and the conveyor belt 34, waiting for new goods to be stored. When both the upper and lower storage areas store goods, the goods below will be transported by the conveyor belt 34 first. When the lifting platform 2 descends to the lowest end, the goods on the lifting platform 2 will be placed on the conveyor belt 34 again for movement. This greatly increases the carrying capacity of the one-way transportation of the express delivery transportation component and greatly improves the transportation and sorting efficiency.

[0032] Reference Figure 5 、 Figure 6 and Figure 7, a driving roller 252 is rotatably connected in the first groove 25. The driving roller 252 is below the rotating column 251 and abuts against the rotating column 251. A driving shaft is rotatably connected in the lifting table 2. The driving shaft and the driving roller 252 are connected by bevel gears. In Embodiment 1, the number of driving shafts is 2, and the two driving shafts are driven by gears, so that the rotation directions of the two driving shafts are opposite, so that the rotation directions of the rotating rollers on both sides are opposite, and the rotating columns 251 on both sides can move towards the center position. A first rotating shaft 231 is rotatably connected in one of the optical axes. A bevel gear connected to the driving shaft is provided at the top end of the first rotating shaft 231 in the vertical direction. The bottom end of the optical axis is fixed with a mounting bracket 232 by welding. The driving shaft can penetrate through the mounting bracket 232. The mounting bracket 232 is rotatably connected with a second rotating shaft. The mounting bracket 232 makes the first rotating shaft 231 and the second rotating shaft perpendicular to each other. The first rotating shaft 231 and the second rotating shaft are connected by bevel gears; a rack 235 is fixedly connected to the side plate 12, and a gear disc 234 is installed at the end of the second rotating shaft. The outside of the gear disc 234 meshes with the rack 235. In this way, when a relative movement occurs between the optical rod 23 and the vehicle body 1, a relative movement occurs between the gear disc 234 and the rack 235, thereby driving the gear disc 234 to rotate. The rotation generated by the gear disc 234 is transmitted to the rotating column 251 through the first rotating shaft 231, the second rotating shaft, the driving shaft, and the driving roller 252. In this way, there is no need to introduce a new power source to drive the rotation of the rotating column 251, so that the rotating column 251 positions the goods on the lifting table 2 at the center during the rising process.

[0033] Reference Figure 7 , the gear disc 234 and the first rotating shaft 231 can rotate relative to each other. A pawl 2341 is rotatably connected to the gear disc 234. A ratchet tooth 2331 that can mesh with the pawl 2341 is provided on the second rotating shaft. The pawl 2341 and the gear disc 234 are connected by a first spring 2342. In this way, it is ensured that only when the lifting table 2 rises, the gear disc 234 can drive the second rotating shaft to rotate, so that the rotating column 251 can rotate towards the center position of the lifting table 2; when the lifting table 2 descends, the gear disc 234 is disengaged from the second rotating shaft, and the rotating column 251 stops rotating.

[0034] Reference Figure 8, there are several second grooves 151 provided at the top of the vehicle body 1. The second grooves 151 and the conveyor belt 34 are arranged at intervals in sequence. The projection of the first groove 25 in the vertical direction is located inside the projection of the second groove 151 in the vertical direction. An elevator block 152 is provided in the second groove 151. A return spring 153 is provided between the elevator block 152 and the second groove 151. The return spring 153 forces the elevator block 152 to move upward. When the lifting platform 2 descends, the lifting platform 2 can press the elevator block 152 into the second groove 151; when the lifting platform 2 ascends, the elevator block 152 protrudes above the top surface of the second groove 151 under the action of the return spring 153 to supplement the height difference between the conveying plane of the conveyor belt 34 and the top surface of the vehicle body 1. The elevator block 152 is provided with an avoidance opening for avoiding the power shaft 32.

[0035] The implementation principle of an express transportation component in an embodiment of the present application is as follows: When the lifting platform 2 is in the lowest position, its top surface serves as the main cargo storage platform. At this time, the conveyor belt 34 of the transportation component 3 is slightly higher than the lifting platform 2, which does not affect the normal stacking of goods. When it is necessary to increase the storage capacity, the lifting platform 2 rises smoothly through a precise lead screw 22 - optical rod 23 mechanism. When it rises to the highest position, a second cargo storage space is formed between the lifting platform 2 and the vehicle body 1, realizing the double-layer storage function.

[0036] Secondly, it is the stage of cargo handover and transportation. This process is completely automated without manual intervention. When it is necessary to transport goods, the lifting platform 2 starts to descend slowly, and the conveyor belt 34 of the transportation component 3 immediately rises through the through groove 21 to a position slightly higher than the top surface of the lifting platform 2 and smoothly "takes over" all the goods. At the same time, the elastic elevator blocks 152 on the top of the vehicle body 1 are compressed, perfectly filling the height difference between the conveyor belt 34 and the vehicle body 1 to ensure the continuity of the transportation plane. If the double-layer storage mode is adopted, the conveyor belt 34 will give priority to transporting the lower-layer goods. After all the lower-layer goods are transported out, the lifting platform 2 descends again to make the upper-layer goods naturally fall onto the conveyor belt 34 for continuous transportation. The whole process is smoothly connected, minimizing the stagnation time during cargo transfer to the greatest extent.

[0037] Finally, it is the stage of positioning and stable transportation. This stage ensures the transportation quality through a delicate mechanical linkage mechanism. During the ascending process of the lifting platform 2, the relative movement between the optical rod 23 and the vehicle body 1 drives the driving roller 252 to rotate through the gear-rack 235 transmission, causing the rotating columns 251 distributed on both sides of the lifting platform 2 to swing towards the center, automatically centering and positioning the goods. This action is controlled by a ratchet mechanism to ensure that it is only triggered when the lifting platform 2 ascends and automatically disengages when descending. At the same time, the conveyor belt 34 adopts a pulley 31 drive structure, and the motor provides stable power to ensure the continuity and reliability of cargo transportation. Through the ingenious cooperation of the mechanical structure, the whole system realizes the double improvement of sorting efficiency and transportation capacity without significantly increasing the cost.

[0038] Embodiment 2, refer toFigure 9 , a transportation system, adopting the following technical solution: It includes an express delivery transportation component, several cycloid components 7, a central processing unit, several delivery bins 6, and several detection components 5. The express delivery transportation components are connected in series in sequence to form a circular sorting line 4. The detection components 5 are respectively installed on the moving path of the express delivery transportation components and at the bottom of the lifting platform 2. The delivery bins 6 are sequentially marked with serial numbers along the moving direction of the express delivery transportation components. The specific method is as follows: The serially connected express delivery transportation components are numbered in sequence and information QR codes are pasted. The central processing unit monitors the loading situation of each express delivery transportation component in real time through the detection components 5; the sorting component first places goods on the lifting platform 2 of the express delivery transportation component. When there are goods placed on the lifting platform 2, the lifting platform 2 moves upward, forming a new loading space between the lifting platform 2 and the vehicle body 1. The remaining sorting components place the goods between the lifting platform 2 and the vehicle body 1. The serial number of the delivery bin 6 into which the goods placed below are put is less than the serial number of the delivery bin 6 into which the goods placed above are put; the goods corresponding to the express delivery transportation components are sequentially put into the corresponding delivery bins 6 and enter the next transportation cycle.

[0039] Adopting a double-layer three-dimensional sorting design, the vertical space is utilized twice as much through the intelligent adjustment of the lifting platform 2, and the sorting capacity per unit area is increased by more than 80%; combining the circular sorting line 4 with the QR code tracking technology to achieve real-time monitoring and intelligent scheduling of each trolley, improving the sorting accuracy; compared with the traditional flat sorting line, the processing capacity of this system is increased several times under the same site conditions, which is especially suitable for meeting the sorting requirements during peak business periods such as e-commerce promotions, and at the same time avoids the problem of resource idleness of the fixed sorting line during non-peak periods.

[0040] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
