Description

Technical Field

[0001] The present invention relates to the technical field of logistics sorting equipment, and in particular to an annular seeding wall and a continuous package supply and sorting method. Background Art

[0002] The sowing wall in logistics sorting is an automated or semi-automated device that is mainly used to classify and temporarily store goods (usually small items) according to certain rules (such as orders, delivery routes, etc.). The sowing wall is usually a wall-like structure with multiple storage cells or containers arranged on the wall. When the goods arrive at the sowing wall from the warehouse or conveyor line, the system will distribute the goods to the corresponding storage cells according to pre-set instructions (such as order information).

[0003] For example, if there are multiple customer orders, each containing a different combination of goods, the sowing wall can place the goods required for different orders in different grids, with each grid corresponding to a specific order or delivery unit, to complete the initial sorting and classification of the goods.

[0004] After searching, a seeding wall is disclosed in Chinese patent document CN113562374A. The seeding wall includes a transport track group, a transport trolley, a shelf, and two lifting cabins spaced apart along a first direction. Among them, the lifting cabin is an important part of the transport trolley for lifting the seeding wall, which can transport the transport trolley to the required transport tracks. When the transport trolley moves along the transport track, it transfers the goods to the shelf to realize the sorting of goods. One lifting cabin can lift multiple transport trolleys into the transport track at the same time, and the lifting efficiency is relatively high.

[0005] However, the above-mentioned seeding wall is a linear sorting device, and has the following defects in actual use: 1. The linear seeding wall is arranged in a straight line in layout, which makes it difficult to fully utilize the space of the warehouse. It occupies a large area and the space utilization rate needs to be further improved; 2. The workflow of the linear seeding wall is usually to feed from one end, sort along a straight line, and finally discharge from the other end. The fixed linear process makes it lack flexibility when facing complex and changeable sorting tasks; 3. It is easy for goods to be blocked during transportation, and it is difficult to ensure the continuity of sorting, because all goods are basically transported along a straight line. Once the conveying device in front of a storage grid fails or goods accumulate, it may cause the subsequent goods to be unable to be transported normally, forming a queue, which greatly affects the sorting efficiency. Summary of the invention

[0006] In view of the above technical problems, in a first aspect, the present invention proposes an annular seeding wall, comprising a turntable mechanism, a conveying trolley, a storage shelf and a supply module for supplying goods to the conveying trolley; A plurality of storage shelves are arranged in a ring shape around the turntable mechanism along the rotation axis of the turntable mechanism, a conveying channel for a conveying trolley to pass through is provided between the storage shelves and the turntable mechanism, and the supply module is arranged between the storage shelves; The turntable mechanism is used to drive the conveying trolley to rotate in the conveying channel, so that the conveying trolley can pass through the supply module and each storage shelf; The conveying trolley is installed on the turntable mechanism, and is used to receive goods at the supply module and sort the goods to the storage units on the corresponding storage shelves. A plurality of conveying trolleys are arranged in a circle along the rotation axis of the turntable mechanism; The conveying trolley includes a mounting frame, a material frame and a lifting assembly. The lifting assembly is arranged axially parallel to the rotating shaft of the turntable mechanism and is used to drive the material frame to reciprocate along the height direction of the storage shelf. The material frame is connected to the lifting assembly, and the lifting assembly is connected to the turntable mechanism through the mounting frame.

[0007] In a preferred embodiment according to the present invention, the lifting assembly includes a stand and a synchronous belt unit. The stand is connected to the mounting frame. The synchronous belt unit is mounted on the stand and is used to drive the material frame to reciprocate along the height direction of the storage shelf.

[0008] In a preferred embodiment according to the present invention, a guide mechanism is arranged between the material frame and the vertical frame, the guide mechanism includes a wheel frame and a guide wheel group, the side wall of the material frame is connected to the vertical frame through the wheel frame, the guide wheel group is installed on the wheel frame, and the side wall of the vertical frame is provided with a track surface for contacting the guide wheel group.

[0009] In a preferred embodiment according to the present invention, a conveyor belt for receiving goods and conveying the goods to the storage rack is arranged at the bottom of the material frame.

[0010] In a preferred embodiment according to the present invention, storage units are provided on the storage shelf, and a plurality of storage units are arranged in a rectangular array on the storage shelf, and the openings of the storage units point toward the conveying channel.

[0011] In a preferred embodiment according to the present invention, the storage units are arranged obliquely on the storage shelves.

[0012] In a preferred embodiment of the present invention, the supply module includes a code scanning unit for collecting cargo information and a weighing unit for weighing cargo.

[0013] In a preferred embodiment according to the present invention, a pair of supply modules are arranged between the storage shelves, and the pair of supply modules are symmetrically arranged along the rotation axis of the turntable mechanism.

[0014] In a second aspect, the present invention further proposes a continuous bag supply and sorting method using the above-mentioned annular seeding wall, comprising the following steps: The annular seed wall system is started, the turntable mechanism starts to operate, and a plurality of conveying carts arranged in a circle along the rotation axis of the turntable mechanism rotate in the conveying channel driven by the turntable mechanism; When the transport cart passes through the feeding module, the feeding module supplies the goods to the transport cart, and the material frame of the transport cart receives the goods from the feeding module; As the turntable mechanism continues to rotate, the conveyor trolley brings the goods to the corresponding storage shelf. At this time, the lifting component on the conveyor trolley starts to work, driving the material frame along the axial direction parallel to the rotating shaft of the turntable mechanism to move along the height direction of the storage shelf, so that the material frame reaches a suitable height position, and then sorts the goods to the corresponding storage unit on the storage shelf; During the entire process, the turntable mechanism continuously drives the transport cart to circulate. The transport cart passes through the supply module in turn to obtain the goods, and accurately sorts the goods and places them in the storage units of each storage shelf.

[0015] In a preferred embodiment according to the present invention, the goods to be sorted are placed in the upper bag area of ​​the supply module in a certain order. The supply module transports the individual goods to the supply position in sequence. When the goods arrive at the supply position, the sensor of the supply module detects the presence of the goods and transmits the signal to the control system. The control system determines the target transport trolley to receive the goods based on pre-set rules and the current position and status of the transport trolley.

[0016] Compared with the prior art, the annular seeding wall and continuous bag supply and sorting method provided by the present invention have the following outstanding substantial features and significant improvements: 1. The circular seeding wall drives multiple transport carts to circulate between the storage shelves in a circular layout through a turntable mechanism, realizing continuous package supply and sorting operations. Compared with the traditional linear seeding wall or manual sorting method, it greatly improves the sorting speed and efficiency. Multiple transport carts can receive, transport and sort different goods at the same time, reducing the waiting time for goods. More goods can be processed per unit time, effectively improving the overall operation efficiency of the logistics warehousing link, and is especially suitable for large-scale, high-flow goods sorting scenarios; 2. The annular seeding wall uses its unique annular structure and modular design to make the annular seeding wall highly flexible in layout. Multiple storage shelves are arranged in a ring around the turntable mechanism. The layout can be reasonably adjusted according to the actual conditions such as the warehouse space shape, size and cargo flow distribution, making full use of the warehouse space and improving space utilization. At the same time, for goods of different types, sizes and weights, it only needs to adjust the corresponding sorting rules and the action parameters of the conveyor trolley in the control system to meet the diverse cargo sorting needs without large-scale transformation of the entire equipment structure. It has strong versatility and adaptability. 3. The circular seeding wall uses various components such as turntable mechanism, conveyor trolley, storage shelf and supply module to cooperate with each other to form a relatively stable automatic sorting system. During the design and manufacturing process, each component has undergone strict engineering optimization and quality control to ensure long-term stable operation. In addition, the control system's real-time monitoring and fault warning mechanism for the entire system can promptly detect and handle abnormal situations during equipment operation, further improving the reliability of the equipment, reducing downtime and maintenance costs caused by equipment failures, and ensuring the continuity of logistics operations; 4. The continuous package supply and sorting method can pre-set the cargo type or sorting rules corresponding to each storage shelf in the control system according to the characteristics of the cargo, and in the process of package supply, transportation and sorting, through precise sensor detection, intelligent scheduling of the control system and precise positioning and motion control of the conveying cart, it can ensure that the cargo is accurately sorted to the corresponding storage shelf storage unit. Compared with some automated sorting equipment that relies on manual judgment or has low precision, this high accuracy greatly reduces the sorting error rate, improves the accuracy of cargo storage and management, reduces the confusion and cost increase in subsequent logistics links caused by erroneous sorting, and realizes highly automated sorting operations. Compared with the traditional method of sorting that relies on a large number of manual workers, it significantly reduces the dependence on manpower, and only requires a small number of operators to perform simple operations such as equipment monitoring, maintenance and packaging operations, which greatly reduces labor costs.

DETAILED DESCRIPTION

[0025] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-Figure 7 As shown, an annular seeding wall proposed in an embodiment of the present invention is intended to further optimize the design of the existing linear seeding wall in terms of layout, sorting continuity and sorting efficiency.

[0027] The annular seeding wall proposed in the embodiment of the present invention utilizes various components such as a turntable mechanism, a conveying trolley, a storage shelf, and a supply module to cooperate with each other to form a relatively stable automatic sorting system. During the design and manufacturing process, each component undergoes strict engineering optimization and quality control to ensure long-term stable operation. In addition, the control system's real-time monitoring of the entire system and the fault warning mechanism can promptly detect and handle abnormal situations during the operation of the equipment, further improving the reliability of the equipment, reducing downtime and maintenance costs caused by equipment failures, and ensuring the continuity of logistics operations.

[0028] like Figure 1 Combination Figure 2 As shown, a circular seeding wall includes a turntable mechanism 1, a conveying trolley 2, a storage shelf 3 and a supply module 4 for supplying goods to the conveying trolley 2. A plurality of storage shelves 3 are arranged in a ring shape around the turntable mechanism 1 along the rotation axis of the turntable mechanism 1. A conveying channel 5 for the conveying trolley 2 to pass through is provided between the storage shelves 3 and the turntable mechanism 1. The supply module 4 is arranged between the storage shelves 3.

[0029] The turntable mechanism 1 is used to drive the transport trolley 2 to rotate in the transport channel 5 , so that the transport trolley 2 can pass through the supply module 4 and each storage shelf 3 .

[0030] The transport trolley 2 is mounted on the turntable mechanism 1, and is used to receive goods at the supply module 4 and sort the goods to the storage units 31 on the corresponding storage shelves 3. A plurality of transport trolleys 2 are arranged in a circle along the rotation axis of the turntable mechanism 1.

[0031] like Figure 6As shown, the conveying trolley 2 includes a mounting frame 21, a material frame 22 and a lifting assembly 23. The lifting assembly 23 is arranged parallel to the axis of the rotating shaft of the turntable mechanism 1 and is used to drive the material frame 22 to reciprocate along the height direction of the storage shelf 3. The material frame 22 is connected to the lifting assembly 23. The lifting assembly 23 is connected to the turntable mechanism 1 through the mounting frame 21.

[0032] For example, the lifting assembly 23 includes a stand 231 and a synchronous belt unit 232, and the stand 231 is connected to the mounting frame 21. The synchronous belt unit 232 is installed on the stand 231, and is used to drive the material frame 22 to reciprocate along the height direction of the storage shelf 3.

[0033] In this way, the synchronous belt unit 232 has the characteristic of high transmission accuracy. When driving the material frame 22 to reciprocate along the height direction of the storage shelf 3, the position of the material frame 22 can be accurately controlled so that it can accurately reach the height that matches each storage unit 31. This accuracy is crucial to ensure that the goods are accurately sorted and placed in the designated storage unit 31, greatly reducing the sorting errors caused by inaccurate positioning of the material frame 22, and improving the sorting accuracy and operation quality of the entire annular seeding wall. For example, when handling some small or precision goods that require high placement accuracy, the synchronous belt unit 232 can ensure that the material frame 22 can accurately stop at the appropriate height every time to avoid collision or misplacement of goods.

[0034] In addition, the synchronous belt drive runs smoothly, and can effectively reduce vibration and impact in the process of driving the material frame 22 to rise or fall. This is of great significance for protecting the integrity of the goods, especially for some fragile goods or goods that are sensitive to transportation conditions. The smooth movement can prevent the goods from being damaged due to violent shaking in the material frame 22. At the same time, the smooth operation is also conducive to extending the service life of the equipment, reducing the wear and fatigue damage caused by vibration and impact to the lifting component 23 itself and the mounting frame 21, material frame 22 and other components connected thereto, reducing the maintenance cost and failure rate of the equipment, and ensuring that the annular seed wall can operate stably and reliably for a long time.

[0035] In addition, the structural design of the connection between the stand 231 and the mounting frame 21 makes the overall structure of the lifting assembly 23 relatively compact. In the limited space of the annular seeding wall, this compact structure can be better laid out and installed, reducing the occupation of the surrounding space, which is conducive to the optimal configuration of the entire device in space. Compared with some lifting devices with loose structures and large volumes, it can enable the annular seeding wall to achieve a smaller footprint or more reasonable space utilization while maintaining efficient sorting functions, which is particularly critical for logistics warehousing environments with tight warehouse space resources, and can improve the space utilization rate and storage capacity of the warehouse.

[0036] like Figure 6As shown, a guide mechanism 24 is provided between the material frame 22 and the stand 231. The guide mechanism 24 includes a wheel frame 241 and a guide wheel group 242. The side wall of the material frame 22 is connected to the stand 231 through the wheel frame 241. The guide wheel group 242 is mounted on the wheel frame 241. The side wall of the stand 231 is provided with a track surface for contacting the guide wheel group 242.

[0037] The guide wheel set 242 rolls along the track surface of the side wall of the stand 231, which can provide accurate and stable guidance for the reciprocating motion of the material frame 22 in the height direction. This effectively limits the unstable motion such as lateral deviation, shaking or twisting of the material frame 22, ensuring that the material frame 22 always maintains a stable and straight motion trajectory during the lifting process.

[0038] For example, when the annular seed wall is in high-speed operation and the conveying trolley 2 frequently starts, stops and changes speed, the guide mechanism 24 can prevent the material frame 22 from being disturbed by factors such as inertia and stably reach the target storage unit 31 position, greatly improving the reliability and accuracy of the entire sorting operation and reducing the risk of goods falling or misplacing due to unstable movement of the material frame 22.

[0039] Through the contact and cooperation between the guide wheel group 242 and the track surface, the weight of the material frame 22 and the goods it carries can be better shared, and the load force can be evenly transferred to the stand 231 structure. This design allows the lifting component 23 to maintain good mechanical properties and operating conditions when facing goods of different weights. Whether it is a lighter small item or a heavier large item, the guide mechanism 24 can assist the lifting component 23 to smoothly complete the lifting operation of the material frame 22, avoiding deformation or damage of components due to excessive local force, significantly improving the adaptability of the annular seeding wall to diversified loads, and broadening the range and application scenarios of goods that can be handled.

[0040] According to some preferred embodiments of the present invention, a conveyor belt 25 for receiving goods and conveying the goods to the storage shelf 3 is provided at the bottom of the material frame 22. When the conveying trolley 2 reaches the position corresponding to the storage shelf 3 and needs to sort the goods to the storage unit 31, the conveyor belt 25 can smoothly push the goods out. Its continuous motion characteristics avoid the unstable state caused by sudden start and stop or jamming when the goods are transferred between the material frame 22 and the storage shelf 3, so that the goods can enter the storage unit 31 more smoothly.

[0041] like Figure 3As shown, the storage shelf 3 is provided with storage units 31, and a plurality of storage units 31 are arranged in a rectangular array on the storage shelf 3, and the openings of the storage units 31 point to the conveying channel 5. The storage units 31 arranged in a rectangular array can make full use of the space of the storage shelf 3. The rectangular layout can achieve a close arrangement, reduce space gaps and waste, so that the storage shelf 3 can accommodate more storage units 31 within a limited floor space, thereby significantly improving the storage capacity of the warehouse.

[0042] In addition, the rectangular array arrangement provides a clear logical structure for cargo classification management. The storage units 31 can be planned and numbered according to the type, batch, production date and other attributes of the cargo, so that each storage unit 31 has a clear location identification and corresponding cargo information. This regular layout facilitates quick positioning and querying of the storage location of specific cargo, and facilitates inventory counting, cargo allocation and order processing. For example, when a batch of cargo needs to be found, the storage unit 31 where it is located can be quickly determined based on the classification area to which it belongs and the corresponding rectangular array coordinates, reducing the time and labor cost of finding cargo.

[0043] like Figure 5 As shown, the storage unit 31 is arranged obliquely on the storage shelf 3. With such arrangement, when the conveying trolley 2 places the goods on the inclined storage unit 31, due to the effect of gravity, the goods will automatically slide down along the inclined surface and tend to stabilize at the bottom or a specific position of the storage unit 31. This reduces the reliance on complex precision pushing mechanisms or additional sorting processes. Even if the placement position of the goods is slightly deviated, it can be automatically adjusted to a suitable posture and position with the help of gravity, ensuring that the placement of the goods in the storage unit 31 is more regular and orderly, and improving the stability and consistency of the goods storage.

[0044] like Figure 4 As shown, a pair of supply modules 4 are provided between the storage shelves 3, and the pair of supply modules 4 are symmetrically arranged along the rotation axis of the turntable mechanism 1. The symmetrically arranged supply modules 4 can enable the annular seeding wall to maintain a better load balance during operation. When multiple conveying carts 2 are operating at different positions at the same time, the two supply modules 4 can evenly distribute the goods to the conveying carts 2 on both sides to avoid uneven force on the turntable mechanism 1 and eccentric loading due to the concentration of supplies on one side. This balanced load design helps to reduce the wear of the turntable mechanism 1, reduce vibration and noise during equipment operation, extend the service life of the equipment, and also improve the stability and reliability of the entire system operation.

[0045] In addition, the two supply modules 4 can perform cargo supply operations at the same time, which greatly increases the total amount of cargo available for sorting per unit time. Compared with a single supply module 4, more packages or items can be processed in the same time, significantly improving the sorting efficiency of the circular seeding wall. Especially during the peak period of logistics or when handling large-scale cargo, the symmetrically arranged supply modules 4 can give full play to their advantages of parallel operation, so that the conveying trolley 2 can obtain and sort the cargo more quickly, reducing the waiting time of the cargo in the supply link, thereby improving the cargo processing throughput of the entire logistics warehousing system, meeting the sorting needs of high traffic, and improving the overall timeliness of logistics operations.

[0046] According to some preferred embodiments of the present invention, Figure 7 As shown, the supply module 4 includes a code scanning unit 41 for collecting goods information and a weighing unit 42 for weighing goods. The code scanning unit 41 is used to quickly read the barcode, QR code or other identification code on the goods to obtain detailed information of the goods, such as product name, model, batch, production date, place of origin, etc. It can realize accurate identification and classified storage of goods, ensuring that the goods are accurately sorted to the corresponding storage shelf 3 or storage unit 31.

[0047] The weighing unit 42 weighs the goods to obtain accurate weight data of the goods. In the process of logistics and distribution, weight information is an important basis for calculating freight, arranging transportation tools and planning transportation routes. By obtaining the weight of the goods in the supply module 4, it is possible to prepare for the subsequent logistics links in advance, avoiding problems such as freight calculation errors, waste of transportation resources or overloading caused by inaccurate or missing weight data. In addition, weight data can also be used to evaluate the carrying capacity of warehouse shelves and optimize the storage layout of goods. Storage locations can be reasonably allocated according to the weight of the goods, ensuring the safety and stability of the storage shelves 3, and improving the effective utilization of warehouse space.

[0048] When the annular seeding wall proposed in the embodiment of the present invention is used, various components such as the turntable mechanism 1, the conveying trolley 2, the storage shelf 3 and the supply module 4 cooperate with each other to form a relatively stable automatic sorting system, which realizes continuous supply of packages without waiting, and the equipment has a small floor area, is easy to install, adjust and move, and the sorting rate can reach 3500 pieces / hour. Specifically, it includes the following steps: The annular seed wall system is started, the turntable mechanism 1 begins to operate, and a plurality of conveying carts 2 arranged in a circle along the rotation axis of the turntable mechanism 1 rotate in the conveying channel 5 driven by the turntable mechanism 1 .

[0049] According to the characteristics of the goods to be sorted, the goods type or sorting rules corresponding to each storage shelf 3 are pre-set in the control system. For example, a specific shelf is set to store goods of a specific size, weight range or product category, and a unique identification code is assigned to each storage unit 31 to accurately control the sorting position of the goods.

[0050] The code scanning unit 41 and the weighing unit 42 in the supply module 4 are calibrated to ensure that they can accurately collect the information and weight data of the goods. At the same time, check whether the conveying channel 5 is unobstructed and whether each storage unit 31 of the storage shelf 3 is in a state where it can receive goods.

[0051] The goods to be sorted are placed in a certain order in the upper bag area of ​​the feeding module 4. The feeding module 4 can use belt conveying, roller conveying or robot transportation to transport individual goods to the feeding position in sequence.

[0052] When the transport trolley 2 passes through the supply module 4 , the supply module 4 supplies goods to the transport trolley 2 , and the material frame 22 of the transport trolley 2 receives the goods from the supply module 4 .

[0053] As the turntable mechanism 1 continues to rotate, the conveying cart 2 brings the goods to the corresponding storage shelf 3. At this time, the lifting component 23 on the conveying cart 2 starts to work, and it drives the material frame 22 to move along the height direction of the storage shelf 3 along the axial direction parallel to the rotating shaft of the turntable mechanism 1, so that the material frame 22 reaches a suitable height position, and then sorts the goods to the corresponding storage unit 31 on the storage shelf 3.

[0054] The target conveying trolley 2 is driven by the turntable mechanism 1 to move to the supply position of the feeding module 4. At this time, the material frame 22 of the conveying trolley 2 is in a suitable receiving position, and the feeding module 4 pushes or places the goods into the material frame 22 smoothly.

[0055] After the conveying trolley 2 is loaded with goods, as the turntable mechanism 1 continues to rotate, during the movement, the lifting assembly 23 of the conveying trolley 2 is adjusted according to the height information of the storage shelf 3. Under the support of the stand 231, the synchronous belt unit 232 in the lifting assembly 23 drives the material frame 22 to move along the height direction of the storage shelf 3, so that the material frame 22 reaches a height that matches the target storage unit 31. The guide mechanism 24 (including the wheel frame 241 and the guide wheel group 242) between the material frame 22 and the stand 231 ensures that the material frame 22 maintains a stable linear motion trajectory during the lifting process to avoid shaking or deviation.

[0056] When the conveying trolley 2 reaches the position corresponding to the target storage shelf 3, the conveyor belt 25 at the bottom of the material frame 22 starts to sort the goods into the corresponding storage unit 31 of the storage shelf 3 in a stable and gentle manner. Since the storage unit 31 is arranged at an angle on the storage shelf 3, the goods will automatically slide down under the action of gravity after entering the storage unit 31 and tend to stabilize in a suitable position, which is convenient for subsequent storage management and retrieval operations.

[0057] During the whole process, the turntable mechanism 1 continuously drives the conveying trolley 2 to rotate in a circular manner. The conveying trolley 2 sequentially passes through the supply module 4 to obtain the goods, and accurately sorts the goods and places them in the storage units 31 of each storage shelf 3.

[0058] Among them, the goods to be sorted are placed in the upper bag area of ​​the supply module 4 in a certain order. The supply module 4 transports the individual goods to the supply position in sequence. When the goods arrive at the supply position, the sensor of the supply module 4 detects the presence of the goods and transmits the signal to the control system. The control system determines the target conveying trolley 2 to receive the goods based on pre-set rules and the current position and status of the conveying trolley 2.

[0059] The present invention is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present invention may also have other implementation modes. For those skilled in the art, any technical solutions formed by any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
