[0044] With the development of intelligent technologies such as the Internet of Things (IoT), artificial intelligence (AI), and big data, the demand for transforming and upgrading the traditional logistics industry using these technologies is becoming increasingly strong, making intelligent logistics a research hotspot in the logistics field. Intelligent logistics utilizes AI, big data, and various information sensors, RFID technology, GPS, and other IoT devices and technologies. It is widely applied to basic activities such as material transportation, warehousing, distribution, packaging, loading and unloading, and information services, enabling intelligent analysis and decision-making, automated operation, and high-efficiency optimization in material management. IoT technologies include sensing devices, RFID technology, laser infrared scanning, and infrared sensing identification. The IoT effectively connects materials in logistics to the network, enabling real-time monitoring of materials and sensing environmental data such as humidity and temperature in warehouses to ensure proper storage conditions. Big data technology can sense and collect all data in logistics, uploading it to the information platform's data layer for filtering, mining, and analysis. Ultimately, this provides precise data support for business processes such as transportation, warehousing, storage, picking, packaging, sorting, outbound, inventory, and distribution. The application of artificial intelligence in logistics can be broadly divided into two categories: 1) AI-powered intelligent equipment such as unmanned trucks, AGVs, AMRs, forklifts, shuttles, stacker cranes, unmanned delivery vehicles, drones, service robots, robotic arms, and smart terminals replace some manual labor; 2) Software systems driven by computer vision, machine learning, operations research, and other technologies or algorithms, such as transportation equipment management systems, warehouse management systems, equipment scheduling systems, and order allocation systems, improve manual efficiency. With the research and advancement of smart logistics, this technology has been applied in numerous fields, including retail and e-commerce, electronics, tobacco, pharmaceuticals, industrial manufacturing, footwear and apparel, textiles, and food.

[0045] Currently, with the rapid development of the logistics industry, the volume of goods is increasing dramatically. To improve the sorting efficiency of goods, sorting devices are becoming increasingly common in the material handling industry.

[0046] In related technologies, the sorting device uses a piece-by-piece feeding method, meaning that individual items are fed to the sorting device one by one through a feeding platform. Then, the sorting device sorts each item individually.

[0047] The aforementioned method of feeding and sorting goods one item at a time requires the supply platform to repeatedly feed goods when there are multiple items in the same order. For example, if there are multiple items of the same Stockkeeping Unit (SKU) in the same order, these SKUs still need to be sorted repeatedly, resulting in low sorting efficiency. In addition, multiple items in the same order will occupy multiple sorting stations on the sorting device, further affecting sorting efficiency.

[0048] In view of the above-mentioned problems, according to the first aspect of this disclosure, a feeding method 200 is provided. For example... Figure 1 and Figure 3 As shown, the feeding method 200 is applied to the feeding device 20, which includes a loading trolley 21. The feeding method 200 includes steps S11, S12 and S13.

[0049] In step S11, the sorting trolley corresponding to the loading trolley in the target feeding device is determined.

[0050] The loading trolley 21 receives one or more goods to be sorted at the loading position. When the loading trolley 21 receives multiple goods to be sorted at the loading position, the multiple goods to be sorted can be placed side by side on the loading trolley 21 along the conveying path of the loading trolley 21. That is, the multiple goods to be sorted are arranged in rows. For example, the multiple goods to be sorted can be a specified quantity of goods of the same SKU under the same order, and these specified quantities of goods to be sorted are placed in the same row on the loading trolley 21. Moreover, the multiple goods to be sorted on the loading trolley 21, for example, a specified quantity of goods of the same SKU under the same order, can be arranged in a row, that is, the same order row. For example, 12 bags of 999 Cold Relief can be arranged in a row according to the number and quantity, which is the same order row.

[0051] In step S12, when the corresponding sorting trolley 11 moves to the corresponding position of the loading trolley 21, the loading trolley is controlled to move in the same direction relative to the corresponding sorting trolley, and the loading trolley 21 carries one or more goods to be sorted. In step S13, during the process of the loading trolley 21 moving in the same direction relative to the corresponding sorting trolley 11, the loading trolley 21 is controlled to transport the goods to be sorted to the sorting trolley 11.

[0052] In one example, the corresponding sorting cart 11 is loaded with goods to be delivered; step S12 includes: when the sorting cart 11 loaded with goods to be delivered moves to the loading position, controlling the loading cart 21 to move in the same direction relative to the corresponding sorting cart 11.

[0053] Step S13 includes: during the process of the loading trolley 21 moving in the same direction relative to the sorting trolley 11 carrying the goods to be loaded, after the sorting trolley 11 carrying the goods to be loaded loads the goods to be loaded loads onto the target container, the loading trolley 21 is controlled to transport the goods to be sorted to the sorting trolley 11, wherein the target container is located within a predetermined distance range in front of the loading position.

[0054] For example, if a sorting cart 11 is currently carrying a product to be sorted, and the sorting destination of the sorting cart 11 is located in front of the loading position. Figure 3 Along the rotation direction of the sorting trolley 11, there are four loading positions: a first loading position S01, a second loading position S02, a third loading position S03, and a fourth loading position S04. When the sorting trolley 11 rotates counterclockwise, the sorting destination can be located at a first position S1 in front of the first loading position S01, where a container for holding the goods to be loaded can be set up. When the sorting trolley 11 rotates clockwise, the sorting destination is located at a second position S2 in front of the loading position S01, where a container for holding the goods to be loaded can be set up. Taking the sorting trolley 11 rotating counterclockwise as an example, if the existing loading scheme is used, since the sorting trolley 11 is currently carrying goods, the sorting trolley 11 will arrive at... Figure 3 At the first loading position S01, no material can be loaded. The sorting trolley 11 must deliver the goods to be placed into the container after reaching the destination (first position S1) and continue to run counterclockwise until it moves to the next loading position (second loading position S02) before it can load materials again.

[0055] Using the feeding method of this application embodiment, if the system determines that the sorting trolley 11 corresponding to the feeding trolley in the target feeding device is carrying goods to be delivered, and the corresponding sorting destination (e.g., Figure 3The first position S1 is located within a predetermined distance in front of the loading position. The predetermined distance is the maximum travel range when the loading trolley 21 and the sorting trolley 11 move in the same direction. Thus, the loading trolley 21 can move in the same direction as the sorting trolley 11 when the sorting trolley 11 reaches the loading position (first loading position S01). The first position S1 is equipped with a container corresponding to the goods to be loaded. After the sorting trolley 11 finishes loading the goods at the first position S1, that is, after the goods to be loaded are placed into the target container, the loading trolley 21 transports the goods to be sorted to the sorting trolley 11. In this way, the sorting trolley 11 does not need to wait empty to run to the next loading position (e.g., the second loading position S02) for loading, which improves the utilization rate of the sorting trolley and improves the sorting efficiency.

[0056] The identification code on the goods to be sorted can be identified by the detection device. The identification code can be, for example, a barcode or a QR code, to obtain the goods information of the goods to be sorted. Based on the goods information, the sorting cart corresponding to multiple goods to be sorted under the same order can be determined.

[0057] There can be multiple sorting carts 11, and these carts 11 can move at a uniform speed along a first path r1. The first path r1 can be circular, toroidal, curved, or straight. In one example, the corresponding position can be the loading position of the loading cart 21 when the sorting cart 11 reaches it, that is, the position where the sorting cart 11 and the loading cart 21 are aligned. At this position, the loading cart 21 moves in the same direction relative to the corresponding sorting cart 11, and the speed of the loading cart 21 can be the same as the speed of the sorting cart 11. During the process of moving in the same direction at the same speed as the sorting cart 11, the loading cart 21 puts multiple goods to be sorted placed side by side onto the sorting cart 11.

[0058] In another example, the corresponding position can be that the sorting trolley 11 is behind the loading trolley 21. That is, when the sorting trolley 11 has not reached the loading position of the loading trolley 21, the loading trolley 21 begins to move in the same direction as the corresponding sorting trolley 11. The speed of the loading trolley 21 can be less than the speed of the sorting trolley 11. When the sorting trolley 11 reaches a position that is approximately aligned with the loading trolley 21, multiple goods to be sorted are transported to the sorting trolley 11.

[0059] In another example, the corresponding position can be that the sorting trolley 11 is in front of the loading trolley 21, that is, when the sorting trolley has passed the loading position of the loading trolley 21, the loading trolley 21 begins to move in the same direction relative to the corresponding sorting trolley 11, wherein the movement speed of the loading trolley 21 is greater than the movement speed of the sorting trolley 11. When the loading trolley 21 reaches a position that is approximately aligned with the sorting trolley 11, multiple goods to be sorted are transported to the sorting trolley 11.

[0060] In summary, the feeding method 200 of this disclosure transports goods to be sorted to the sorting cart during the co-directional movement of the loading cart 21 relative to the corresponding sorting cart 11. This method can extend the conveying time of the loading cart 21 and ensure the accuracy of goods delivery. It also ensures reliable delivery even when multiple goods to be sorted are transported together to a single sorting cart 11, thereby improving sorting efficiency.

[0061] In one embodiment, after step S13, the feeding method 200 further includes: retracting the loading trolley 21 to the loading position. The loading trolley 21 can receive multiple goods to be sorted at once. Goods can be placed on the loading trolley 21 manually, or they can be buffered by other devices before being transported to the loading trolley 21. After each shipment of goods to be sorted to the corresponding sorting trolley 11, the loading trolley 21 returns to a fixed loading position, facilitating the receipt of the next batch of goods. Since the loading trolley 21 can move with the sorting trolley 11, and the manual or other devices do not need to move, they can wait at the loading position for the returned and emptied loading trolley 21 before supplying goods again. The buffering device can also buffer goods in advance, further improving efficiency.

[0062] In one example, the feeding device 20 further includes a drive unit. Step S12 includes controlling the drive unit to drive the loading trolley 21 to move in the same direction relative to the corresponding sorting trolley 11. Controlling the loading trolley 21 to return to the loading position includes controlling the drive unit to drive the loading trolley back to the loading position.

[0063] In this embodiment, the loading trolley 21 can be driven to move in the same direction as the sorting trolley 11 by a driving component, and the loading trolley 21 can also be driven to return to the loading position. The driving component can be started according to the position of the corresponding sorting trolley 11, driving the loading trolley 21 to move in the same direction to the side of the sorting trolley 11, and can have the same angular velocity as the sorting trolley 11, or can be kept to the side for a certain period of time to perform loading.

[0064] The sorting trolley 11 can remain in motion during the sorting process, thus maintaining efficient sorting. For example, the loading trolley 21 can travel along a track 25 set along a second path r2. A drive unit propels the loading trolley 21 along the track 25. This makes the loading trolley a rail-guided electric vehicle (RGV), i.e., actively driven, traveling on the track 25. Figure 6 and Figure 7As shown, taking the first path r1 and the second path r2 as a circle as an example. When the corresponding sorting trolley 11 rotates to the corresponding position of the loading trolley 21, the loading trolley 21 moves counterclockwise relative to the corresponding sorting trolley 11 on the track 25 by a drive component. During the counterclockwise movement of the loading trolley 21 relative to the corresponding sorting trolley 11, the loading trolley 21 transports the goods to be sorted to the corresponding sorting trolley 11. After the loading trolley 21 transports the goods to be sorted to the corresponding sorting trolley 11, the loading trolley 21 is actively driven by a drive component to rotate clockwise and return to the loading position, so that the empty loading trolley 21 can receive one or more other goods to be sorted.

[0065] The loading trolley 21 is actively driven by a drive component, which makes it easy to control the speed of the loading trolley 21.

[0066] In one embodiment, the feeding device 20 further includes a first linkage component. Step S12 includes controlling the first linkage component to cooperate with the sorting trolley 11, so that the sorting trolley 11 drives the loading trolley 21 to move in the same direction relative to the corresponding sorting trolley 11.

[0067] In this embodiment, the first linkage can be controlled so that the loading trolley 21 can be driven by the sorting trolley 11. With the power of the sorting trolley 11, the loading trolley 21 can move in the same direction relative to the corresponding sorting trolley 11, remaining lateral and extending the loading time. The first linkage can be installed on the loading trolley 21, for example, a hook that can extend and retract. By extending the hook, it can hook onto the corresponding sorting trolley 11, thereby achieving unidirectional movement. Alternatively, it can be an electromagnet; by energizing the electromagnet, a magnetic force is formed between the metal sorting trolleys 11. The first linkage can also be installed on both the loading trolley 21 and the sorting trolley 11, or it can be installed only on the sorting trolley 11.

[0068] In one example, the first linkage can be a latch structure. When the latch structure is opened, the sorting trolley 11 is connected to the loading trolley 21, so that the sorting trolley 11 drives the loading trolley 21 to move in the same direction relative to the corresponding sorting trolley 11.

[0069] In another example, the first linkage can be an electromagnet. When the electromagnet is turned on, the loading trolley 21 uses the magnetic attraction of the electromagnet to sort the unloading trolley 11, causing the sorting trolley 11 to move in the same direction as the loading trolley 21 relative to the corresponding sorting trolley 11.

[0070] The feeding method 200 of this embodiment cooperates with the sorting trolley 11 via a first linkage on the loading trolley 21, causing the loading trolley 21 to move on the track 25 via the sorting trolley 11. This allows the sorting trolley 11 to be a non-powered trolley, passively moving in the same direction as the loading trolley 21, eliminating the need for a drive mechanism and saving costs. Furthermore, it extends the conveying time of the loading trolley 21 and improves conveying accuracy and reliability.

[0071] In one embodiment, the feeding device 20 further includes an elastic return member. Controlling the loading trolley 21 to return to the loading position includes: controlling the first linkage to disengage from the sorting trolley 11, so that the sorting trolley 11 returns to the loading position under the action of an external force.

[0072] In this embodiment, an elastic recovery member can be provided and kept connected to the loading trolley 21. The loading trolley 21 is moved by the sorting trolley 11 through the first linkage member. After the connection is released, the stretched elastic recovery member can use elastic force to make the loading trolley 21 return to the loading position.

[0073] Taking the first linkage as an example of a latching structure, when the corresponding sorting trolley 11 moves to the corresponding position of the loading trolley 21, the latching structure opens, and the sorting trolley 11 and the loading trolley 21 are connected together, causing the sorting trolley 11 to drive the loading trolley 21 to move together from the loading position to the predetermined position relative to the corresponding sorting trolley 11. During the movement of the loading trolley from the loading position to the predetermined position, the loading trolley 21 transports the goods to be sorted to the sorting trolley 11, and the elastic return member is in a stretched state with a certain elastic force. After the loading trolley 21 transports the goods to be sorted to the sorting trolley 11, the latching structure unlocks, allowing the loading trolley 21 to be released from the restraint of the sorting trolley 11. At this time, the elastic return member returns from the stretched state to the initial state, and the elastic force of the elastic return member causes the loading trolley 21 to return to the receiving position to receive other goods to be sorted.

[0074] In one embodiment, the feeding device 20 further includes a buffer trolley 22. The method includes: controlling the buffer trolley 22 to receive one or more goods to be sorted; and controlling the buffer trolley 22 to transport one or more goods to be sorted to a loading trolley 21 located at a loading position.

[0075] After the buffer trolley 22 transports multiple goods to be sorted to the loading trolley 21, the loading trolley 21 moves in the same direction as the sorting trolley 11 and leaves the loading position. The buffer trolley 22 can continue to receive other goods to be sorted. When the loading trolley 21 returns to the loading position, the buffer trolley 22 can quickly transport other goods to be sorted to the loading trolley 21, so that the loading trolley 21 can continuously and uninterruptedly transport goods to be sorted to the sorting trolley 11. This improves the efficiency of transporting goods to the sorting trolley, thereby improving the sorting efficiency.

[0076] In some embodiments, one or more goods to be sorted correspond to the same container. The feeding method 200 further includes: identifying a corresponding sorting cart based on one or more goods to be sorted.

[0077] The identification code on the goods to be sorted can be identified by a detection device. The identification code can be, for example, a barcode or QR code, to obtain the goods information. Based on the goods information, the sorting cart and the corresponding container for multiple goods to be sorted under the same order can be determined. The corresponding sorting cart will then place multiple goods to be sorted together into the same container.

[0078] Compared to the traditional method where multiple items of the same SKU under the same order need to be fed and sorted one by one, the sorting efficiency is greatly improved. In addition, since multiple items to be sorted, such as multiple items of the same SKU under the same order, are put into one corresponding sorting cart 11, the occupation of other sorting carts 11 is reduced, further improving sorting efficiency.

[0079] A control device is provided according to a second aspect of the present disclosure, comprising: a processor; and a memory for storing processor-executable instructions; wherein the processor is configured to perform the feeding method described in any of the above embodiments.

[0080] A sorting method 300 is provided according to a third aspect of embodiments of the present disclosure. For example... Figure 2 As shown, sorting method 300 is applied to sorting equipment 100, which includes sorting cart 11 and containers. Sorting method 300 includes steps S21 and S22.

[0081] In step S21, the goods to be sorted are transported to the sorting cart 11 by the feeding method 200 of any embodiment of the first aspect described above.

[0082] In step S12, the sorting trolley 11 transports the goods to be sorted to the corresponding container location and places the goods to be sorted into the corresponding container.

[0083] The sorting method 300 of this embodiment transports goods to be sorted to a sorting cart by means of a loading cart 21 moving in the same direction relative to a corresponding sorting cart 11. This method extends the transport time of the loading cart 21, ensuring the accuracy of goods transport. It also ensures reliable delivery even when multiple goods to be sorted are transported together to a single sorting cart 11. Because the transport time of the loading cart 21 is extended, multiple goods to be sorted can be placed into the same corresponding container via the corresponding sorting cart 11, significantly improving sorting efficiency compared to the traditional method of feeding and sorting individual goods one by one. Furthermore, since multiple goods to be sorted are placed through a single sorting cart 11, the occupancy of other sorting carts 11 is reduced, further improving sorting efficiency.

[0084] According to a fourth aspect of the present disclosure, a feeding device is provided, which transports one or more goods to be sorted to a sorting cart during the process of a feeding cart moving in the same direction relative to a sorting cart, thereby improving sorting efficiency.

[0085] like Figure 3 and Figure 4 As shown, the feeding device 20 of this embodiment can be applied to the sorting equipment 100 to feed the sorting cart 11 moving along the first path r1. The sorting cart 11 is used to sort one or more goods to be sorted.

[0086] Sorting equipment 100 may include a sorting device 10 and a receiving device 30. The sorting device 10 may include multiple sorting carts 11, which can move along a first path r1. For example, the first path r1 may be circular, toroidal, curved, or straight. A second path r2 may be adapted to the first path r1, i.e., it may also be circular, toroidal, curved, or straight. The receiving device 30 may include multiple containers. The sorting carts 11 can place one or more goods to be sorted into the containers.

[0087] like Figure 3 and Figure 6 As shown, the feeding device 20 of this disclosure may include a loading mechanism, which may include a loading trolley 21 for receiving one or more goods to be sorted at the loading position. When the corresponding sorting trolley 11 moves to the corresponding position of the loading trolley 21, the loading trolley 21 moves in the same direction relative to the corresponding sorting trolley 11, and during this movement, the loading trolley 21 transports the goods to be sorted to the sorting trolley 11.

[0088] In one example, a sorting cart and its corresponding container can be determined based on one or more goods to be sorted. Multiple goods to be sorted can correspond to the same container. For instance, a detection device can identify the identification code on the goods to be sorted; this code could be a barcode, QR code, etc., to obtain the goods information. Based on this information, the sorting cart and its corresponding container for multiple goods under the same order can be determined. Again, multiple goods under the same order can correspond to the same container.

[0089] The loading trolley 21 receives multiple goods to be sorted at the loading position. These goods can be placed side-by-side on the loading trolley 21 along its conveying path, i.e., arranged in rows. When the sorting trolley 11 corresponding to the multiple goods to be sorted moves to the corresponding position on the loading trolley 21, the loading trolley 21 moves in the same direction relative to the corresponding sorting trolley 11, and during this movement, it transports the goods to be sorted to the sorting trolley 11. The speed of the loading trolley 21 can be the same as or different from the speed of the sorting trolley 11. In one example, the corresponding position can be the loading position of the sorting trolley 11 upon arrival at the loading trolley 21, i.e., the position where the sorting trolley 11 and the loading trolley 21 are aligned. At this position, the loading trolley 21 moves in the same direction as the corresponding sorting trolley 11, and the speed of the loading trolley 21 can be the same as the speed of the sorting trolley 11. During the process of moving in the same direction at the same speed as the sorting trolley 11, the loading trolley 21 delivers multiple goods placed side by side to the sorting trolley 11. In another example, the corresponding position can be that the sorting trolley 11 is behind the loading trolley 21. That is, before the sorting trolley 11 reaches the loading position of the loading trolley 21, the loading trolley 21 begins to move in the same direction as the corresponding sorting trolley 11. The speed of the loading trolley 21 can be less than the speed of the sorting trolley 11. When the sorting trolley 11 reaches a position approximately aligned with the loading trolley 21, it transports multiple goods to be sorted to the sorting trolley 11. In another example, the corresponding position can be that the sorting trolley 11 is in front of the loading trolley 21, that is, when the sorting trolley has passed the loading position of the loading trolley 21, the loading trolley 21 begins to move in the same direction relative to the corresponding sorting trolley 11, wherein the movement speed of the loading trolley 21 is greater than the movement speed of the sorting trolley 11. When the loading trolley 21 reaches a position that is approximately aligned with the sorting trolley 11, multiple goods to be sorted are transported to the sorting trolley 11.

[0090] In summary, the feeding device 20 of this disclosure transports goods to be sorted to the sorting carts by means of the loading cart 21 moving in the same direction relative to the corresponding sorting cart 11. This method can extend the conveying time of the loading cart 21 and ensure the accuracy of the conveying. It also ensures reliable delivery even when multiple goods to be sorted are transported together to a single sorting cart 11. Furthermore, multiple goods to be sorted can be placed into the same corresponding container via the corresponding sorting cart 11, significantly improving sorting efficiency compared to the traditional method of feeding and sorting individual goods one by one. In addition, since multiple goods to be sorted are placed through a single sorting cart 11, the occupation of other sorting carts 11 is reduced, further improving sorting efficiency.

[0091] In one embodiment, after the loading trolley 21 transports the goods to be sorted to the corresponding sorting trolley 11, the loading trolley 21 can return to the loading position so that the empty loading trolley 21 can receive one or more other goods to be sorted.

[0092] By retracting the loading trolley 21 to the loading position, the time for receiving other goods to be sorted can be shortened, the feeding efficiency to the sorting trolley 11 can be improved, and thus the sorting efficiency can be improved.

[0093] In one embodiment, the feeding mechanism further includes a track 25 disposed along a second path r2, the second path r2 being located to the side of the first path r1. The feeding trolley 21 is supported on the track 25 and is capable of moving on the track 25.

[0094] For example, the first path r1 can be a circle, a loop, a curve, or a straight line. The second path r2 can be adapted to the first path r1.

[0095] Taking a circular path r1 and a circular path r2 as an example, the center of the circle of track 25 coincides with the center of the circle of the first path r1, and surrounds the outside or inside of the first path r1. For example, track 25 can be mounted on a support frame and be level with the height of the sorting cart 11 when it rotates. However, it is not limited to this. In another example, track 25 can be located above the first path r1.

[0096] The sorting trolley 11 can rotate counterclockwise along the first path r1. When the corresponding sorting trolley 11 rotates to the corresponding position of the loading trolley 21, the loading trolley 21 rotates counterclockwise relative to the corresponding sorting trolley 11, and during the counterclockwise rotation of the loading trolley 21 relative to the corresponding sorting trolley 11, the loading trolley 21 transports the goods to be sorted to the corresponding sorting trolley 11. Figure 7 (As shown). After the loading trolley 21 transports the goods to be sorted to the corresponding sorting trolley 11, the loading trolley 21 rotates counterclockwise to return to the loading position.Figure 6 (as shown), so that the empty loading trolley 21 can receive one or more other goods to be sorted.

[0097] In one embodiment, the feeding mechanism includes a drive component. The drive component is connected to the feeding trolley 21 and drives the feeding trolley 21 to move on the track 25.

[0098] For example, the loading trolley 21 includes wheels mounted on the track 25. The drive unit can be a motor, which drives the wheels to move on the track 25. This makes the loading trolley a rail-guided electric vehicle (RGV), i.e., actively driven to move on the track 25. As described above, when the corresponding sorting trolley 11 rotates to the corresponding position of the loading trolley 21, the loading trolley 21 actively moves counter-clockwise relative to the corresponding sorting trolley 11 on the track 25, and during this counter-clockwise movement, it transports the goods to be sorted to the corresponding sorting trolley 11. After transporting the goods to be sorted to the corresponding sorting trolley 11, the loading trolley 21 actively rotates clockwise via its motor, returning to the loading position so that the empty loading trolley 21 can receive one or more other goods to be sorted.

[0099] In another embodiment, the loading trolley 21 is provided with a first linkage (not shown) for cooperating with the sorting trolley 11 so that the sorting trolley 11 drives the loading trolley 21 to move in the same direction.

[0100] For example, the first linkage can be a pin, i.e., a pin is provided on the loading trolley 21. The sorting trolley 11 is provided with a socket that mates with the pin, and the pin and the socket can form a latch structure. When the corresponding sorting trolley 11 moves to the corresponding position of the loading trolley 21, the pin on the loading trolley 21 extends and inserts into the socket of the sorting trolley 11. The sorting trolley 11 drives the loading trolley 21 together to move on the track 25 in the same direction and at the same speed. During the movement, the loading trolley 21 transports the goods to be sorted to the sorting trolley 11. However, it is not limited to this. In another example, the first linkage can be a socket, and the sorting trolley 11 is provided with a pin that mates with the socket. When the corresponding sorting trolley 11 moves to the corresponding position of the loading trolley 21, the pin on the sorting trolley 11 extends out into the insertion hole, and the sorting trolley 11 drives the loading trolley 21 to move in the same direction and at the same speed, so that the loading trolley 21 moves on the track 25. During the movement, the loading trolley 21 transports the goods to be sorted to the sorting trolley 11.

[0101] In another example, the first linkage can be an electromagnet, i.e., an electromagnet is provided on the loading trolley 21. The loading trolley 21 attracts the sorting trolley 11 by magnetic attraction through the electromagnet. When the corresponding sorting trolley 11 moves to the corresponding position on the loading trolley 21, the electromagnet on the loading trolley 21 is activated, magnetically attracting the sorting trolley 11, causing the sorting trolley 11 to drive the loading trolley 21 together in the same direction and at the same speed, so that the loading trolley 21 moves on the track 25. During the movement, the loading trolley 21 transports the goods to be sorted to the sorting trolley 11. However, this is not a limitation; in other examples, an electromagnet can be provided on the sorting trolley 11.

[0102] In this embodiment, the feeding device 20 cooperates with the sorting trolley 11 via a first linkage on the loading trolley 21, and the sorting trolley 11 drives the loading trolley 21 to move on the track 25. This allows the sorting trolley 11 to be a non-powered trolley, passively moving in the same direction as the sorting trolley 11, eliminating the need for a drive mechanism and saving costs.

[0103] In one embodiment, since the loading trolley 21 is a non-powered trolley, after the loading trolley 21 transports the goods to be sorted to the sorting trolley 11, it needs to return to the loading position to receive other items to be sorted. Therefore, in this embodiment of the present disclosure, the loading mechanism also includes an elastic return member connected to the loading trolley 21, which uses its elastic return force to return the loading trolley 21 to the loading position.

[0104] For example, the elastic restoring element can be a spring, one end of which can be fixed to the support frame mentioned above for supporting the track 25, and the other end connected to the loading trolley 21. Taking the above latch structure as an example, when the corresponding sorting trolley 11 moves to the corresponding position of the loading trolley 21, the pin on the loading trolley 21 extends and inserts into the insertion hole of the sorting trolley 11. The sorting trolley 11 drives the loading trolley 21 to move together from the loading position in the same direction and at the same speed, so that the loading trolley 21 moves on the track 25 to a predetermined position. During the movement of the loading trolley from the loading position to the predetermined position, the loading trolley 21 transports the goods to be sorted to the sorting trolley 11, and the spring is stretched and has a certain elastic force. When the loading trolley 21 transports the goods to be sorted to the sorting trolley 11, the pin on the loading trolley 21 disengages from the insertion hole of the sorting trolley 11, and the loading trolley 21 is released from the restraint of the sorting trolley 11. At this time, the spring returns from the stretched state to the initial state, and the elastic force of the spring causes the loading trolley 21 to return to the receiving position to receive other goods to be sorted.

[0105] In one embodiment, the feeding trolley 21 moves in the same direction relative to the sorting trolley 11 on the guide rail, unlike the aforementioned loading trolley 21. In the feeding device 20 of this embodiment, the feeding mechanism further includes a reciprocating belt assembly. The loading trolley 21 is fixed to the reciprocating belt assembly, which drives the loading trolley to reciprocate.

[0106] The reciprocating assembly may include a reciprocating motor, a drive roller, a driven roller, and a reciprocating belt. A loading trolley 21 is fixed to the reciprocating belt. The reciprocating belt winds around the drive roller and driven roller along a second path r2, with the drive roller connected to the rotating shaft of the reciprocating motor. The rotation of the reciprocating motor drives the drive roller to rotate, causing the reciprocating belt to reciprocate along the second path r2, so that the loading trolley 21, fixed to the reciprocating belt, moves in the same direction relative to the sorting trolley 11. During this movement, the loading trolley 21 transports goods to be sorted to the sorting trolley 11. After transporting the goods to be sorted to the sorting trolley 11, the loading trolley 21 returns to the loading position to receive other goods to be sorted, improving sorting efficiency.

[0107] In one example, the first path r1 is a straight line, and the second path r2 is a straight line. The reciprocating component can be located to the side of the straight line of the first path r1 and reciprocate along the straight line of the second path r2. In another example, the first path r1 can be circular, including arc segments and straight line segments. The second path r2 can be a straight line, and the reciprocating component can be located to the side of the straight line of the first path r1 and reciprocate along the straight line of the second path r2. It is positioned to the side of the circular straight line segment of the first path r1.

[0108] In another example, the first path r1 can be circular, and the second path r2 can be a straight line, with the second path r2 being a shorter straight line segment. The reciprocating component can be located to the side of the straight line of the first path r1 and reciprocate along the straight line of the second path r2. When the sorting trolley 11 moves to the corresponding position of the loading trolley 21, the reciprocating component drives the loading trolley 21 to move along the straight line of the second path r2. When the loading trolley 21 is within the shorter straight line segment of the second path r2 and is closest to the position of the loading trolley 11, the loading trolley 21 transports the goods to be sorted to the sorting trolley 11.

[0109] The feeding device 20 of this embodiment is configured to connect to the multi-belt assembly, so that the feeding trolley can reciprocate along the straight direction of the second path r2, which can adapt to various movement modes of the sorting trolley 11 and has strong versatility.

[0110] In some embodiments, the loading trolley 21 in the above embodiments may include a conveying mechanism for conveying goods to be sorted to the sorting trolley 11, wherein the conveying mechanism may be any of the following: conveyor belt, conveyor roller, lever, tilting pallet.

[0111] In some embodiments, such asFigure 6 and Figure 7 As shown, the feeding device 20 also includes a buffer mechanism. The buffer mechanism includes a buffer trolley 22, which receives one or more goods to be sorted and transports multiple goods to be sorted together to the loading trolley 21 located at the loading position. The buffer trolley 22 may include a conveying mechanism, which can be any of the following: a conveyor belt, conveyor rollers, levers, or tilting pallets.

[0112] After the buffer trolley 22 transports multiple goods to be sorted to the loading trolley 21, the loading trolley 21 moves in the same direction as the sorting trolley 11. During this process, the buffer trolley 22 can continue to receive other goods to be sorted. When the loading trolley 21 returns to the loading position, the buffer trolley 22 can quickly transport other goods to be sorted to the loading trolley 21, so that the loading trolley 21 can continuously and uninterruptedly transport goods to be sorted to the sorting trolley 11. This can improve loading efficiency and thus improve sorting efficiency.

[0113] In one embodiment, the width of the buffer cart 22 is smaller than the width of the loading cart 21, and the width of the loading cart 21 is smaller than the width of the sorting cart 11.

[0114] On the one hand, the narrower width of the buffer cart 22 allows multiple goods awaiting sorting to be more neatly arranged on it, so that they are lined up in a row, enabling the buffer cart 22 to transport goods to the loading cart row by row. On the other hand, the width of the buffer cart 22 is smaller than the width of the loading cart 21, which ensures that the buffer cart 22 delivers multiple goods awaiting sorting to the loading cart 21 more accurately, improving transport reliability. Similarly, the width of the loading cart 21 is smaller than the width of the sorting cart 11. This ensures that the loading cart 21 delivers multiple goods awaiting sorting to the sorting cart 11 more accurately, improving both transport reliability and sorting efficiency.

[0115] In one example, baffles are installed on both sides of the conveying path of the buffer mechanism. When the buffer trolley 22 transports the goods to be sorted to the loading trolley 21, the baffles can limit the goods to be sorted, preventing them from falling off and improving the reliability of the conveying. In another example, baffles are installed on both sides of the conveying path of the loading mechanism. When the loading trolley 21 transports the goods to be sorted to the sorting trolley 11, the baffles can limit the goods to be sorted, preventing them from falling off and improving the reliability of the conveying, thereby improving the sorting efficiency.

[0116] In one embodiment, the outlet of the buffer mechanism is connected to the inlet of the feeding mechanism, and the outlet of the feeding mechanism is connected to the inlet of the sorting cart. The outlet of the buffer mechanism is higher than the inlet of the feeding mechanism, and the outlet of the feeding mechanism is higher than the inlet of the sorting cart.

[0117] The discharge port of the buffer mechanism is higher than the discharge port of the loading mechanism. This ensures that when the buffer trolley 22 transports goods to be sorted to the loading trolley 21, interference between the goods and the discharge port of the loading mechanism is avoided, resulting in smoother transport, improved transport efficiency, and consequently, improved sorting efficiency. Similarly, the discharge port of the loading mechanism is higher than the inlet of the sorting trolley. This ensures that when the loading trolley 21 transports goods to be sorted to the sorting trolley 11, interference between the goods and the inlet of the sorting trolley is avoided, resulting in smoother transport, improved transport efficiency, and consequently, improved sorting efficiency.

[0118] In some embodiments, the feeding device 20 further includes one or more feeding mechanisms for receiving one or more goods to be sorted and conveying them to the buffer cart 22. Two feeding mechanisms may be provided, namely a first feeding mechanism 23 and a second feeding mechanism 24. The first feeding mechanism 23 and the second feeding mechanism 24 are respectively located on opposite sides of the conveying direction of the buffer mechanism, which saves space and improves sorting efficiency with multiple feeding mechanisms. A detection device may also be provided on the feeding mechanism for identifying the identification code on the goods to be sorted to obtain the goods information. The identification code may be a barcode, QR code, etc. The corresponding sorting cart 11 and the corresponding container can be determined through the goods information.

[0119] In summary, the feeding device 20 of this disclosure first transports one or more goods to be sorted to the buffer trolley 22 of the buffer mechanism for storage via one or more feeding mechanisms. Then, it transports one or more goods to be sorted stored on the buffer trolley 22 to the loading trolley 21 at the loading position. When the corresponding sorting trolley 11 moves to the position corresponding to the loading trolley 21, the loading trolley 21 moves in the same direction relative to the sorting trolley 11. During the movement of the loading trolley 21 relative to the sorting trolley 11, one or more goods to be sorted are transported to the sorting trolley 11. Then, the loading trolley 21 returns to the loading position to receive other one or more goods to be sorted that have been stored in the buffer trolley 22.

[0120] According to a fifth aspect of this disclosure, a sorting device 100 is provided. For example... Figures 3 to 5 As shown, the sorting equipment 100 may include a sorting device 10, one or more feeding devices 20, the control device mentioned above, and a receiving device 30.

[0121] The sorting device 10 includes one or more sorting trolleys 11 moving along a first path. The first path r1 can be circular, annular, curved, or straight. The sorting trolleys 11 are used to sort one or more goods to be sorted. The sorting trolleys 11 may include a conveying mechanism for placing the goods to be sorted into a container, wherein the conveying mechanism can be any of the following: a conveyor belt, conveyor rollers, levers, or tilting pallets. Baffles 13 may also be provided on both sides of the conveying path of the sorting trolleys 11 to prevent the goods to be sorted from falling off during the placement process, thereby improving reliability.

[0122] The feeding device 20 is the feeding device 20 mentioned in any embodiment of the third aspect above. The feeding device 20 feeds the sorting cart 11. For example, multiple feeding devices 20 can be provided, and the multiple feeding devices 20 are arranged along the first path to improve sorting efficiency. Taking the first path as a circle as an example, four feeding devices can be evenly arranged along the circumference of the first path.

[0123] The receiving device 30 includes one or more containers for receiving goods to be sorted from the sorting cart 11. Further, the receiving device 30 may include a conveying mechanism on which multiple containers can be mounted, moving the containers alternately to correspond with the sorting cart 11. The conveyor can be disc-type or linear. Containers can be boxes, such as cardboard boxes or wooden crates; boxes; or bags, such as plastic bags or woven bags.

[0124] The sorting equipment 100 disclosed herein transports goods to be sorted to the sorting cart 11 during the feeding mechanism of the feeding device 20 moving in the same direction relative to the sorting cart. This method reduces the conveying time of the feeding cart 21, allowing multiple goods to be sorted to be transported together to a single sorting cart 11. Thus, multiple goods can be placed into the same corresponding container via the sorting cart 11, significantly improving sorting efficiency compared to the traditional method of feeding and sorting individual goods one by one. Furthermore, since multiple goods are placed into a single sorting cart 11, the occupancy of other sorting carts 11 is reduced, further improving sorting efficiency.

[0125] In one embodiment, the sorting equipment 100 further includes a linkage component. The linkage component includes a first linkage member disposed on the loading trolley 21 and a second linkage member disposed on the sorting trolley 11. The control device is used to control the first and second linkage members to be in a linked state, causing the sorting trolley 11 to move together with the loading trolley 21 from the loading position in the same direction; the control device is also used to control the loading trolley 21 to retract to the loading position under the action of an external force when the first and second linkage members are dislinked.

[0126] In one example, the linkage component can be a latch structure. For instance, the first linkage is a pin, and the second linkage is a locking hole. That is, a pin is provided on the loading trolley 21, and a locking hole that engages with the pin is provided on the sorting trolley 11. The first and second linkages are engaged when the pin is inserted into the locking hole. The first and second linkages are disengaged when the pin disengages from the locking hole.

[0127] In another example, the first linkage is a lock hole, and the second linkage is a pin. That is, a lock hole is provided on the loading trolley 21, and a pin is provided on the sorting trolley 11. The first and second linkages are engaged when the pin is inserted into the lock hole. The first and second linkages are disengaged when the pin disengages from the lock hole.

[0128] The process by which the loading trolley 21 moves in the same direction as the sorting trolley 11 relative to the loading trolley 11 through the opening or unlocking of the latch structure, and the process by which the sorting trolley 11 returns to the loading position, have been described in the above description of the feeding device 20 and will not be repeated here.

[0129] In one embodiment, the first linkage and / or the second linkage is an electromagnet. In one example, an electromagnet is only provided on the loading trolley 21. The sorting trolley 11 is driven by the magnetic attraction of the electromagnet on the loading trolley 21 to the sorting trolley 11, causing the sorting trolley 11 to move in the same direction relative to the sorting trolley 11. In another example, an electromagnet is only provided on the sorting trolley 11. The loading trolley 21 is driven by the magnetic attraction of the electromagnet on the sorting trolley 11 to the sorting trolley 11, causing the sorting trolley 11 to move in the same direction relative to the sorting trolley 11. In yet another example, corresponding electromagnets are provided on the loading trolley 21 and the sorting trolley 11, respectively. The sorting trolley 11 drives the loading trolley 21 to move in the same direction relative to the sorting trolley 11 by the mutual attraction of the electromagnets on each other.

[0130] The process by which the loading trolley 21 moves in the same direction as the sorting trolley 11 relative to the sorting trolley 11 through the magnetic attraction of the electromagnet, and the process by which the sorting trolley 11 returns to the loading position, have been explained in the above description of the feeding device 20, and will not be repeated here.

[0131] In summary, the sorting equipment 100 of this disclosure first transports one or more goods to be sorted to a buffer cart 22 of a buffer mechanism for storage via one or more feeding mechanisms. Then, it transports the one or more goods to be sorted stored on the buffer cart 22 to a loading cart 21 at a loading position. When the corresponding sorting cart 11 moves to the position corresponding to the loading cart 21, the loading cart 21 moves in the same direction relative to the sorting cart 11. During the movement of the loading cart 21 relative to the sorting cart 11, one or more goods to be sorted are transported to the corresponding sorting cart 11. The corresponding sorting cart 11 moves to the corresponding container position and places one or more goods to be sorted into the corresponding container.

[0132] The foregoing description of embodiments of the invention has been provided for purposes of illustration and description. The foregoing description is not exhaustive and is not intended to limit the invention to the exact forms disclosed; various modifications and variations may be made in accordance with the foregoing teachings, or may be derived from the practice of the invention.
