[0039] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] Automated sorting systems are mechanical systems commonly used in industrial production fields such as logistics for the transportation, sorting, and storage of goods. Automated sorting systems are often used in sorting centers. The sorting bin is an important component of an automated sorting system. The sorting bin is mainly used to receive, temporarily store, and sort goods. After the sorting devices (conveyor belts, robotic arms, etc.) in the automated sorting system transport the goods to the sorting bin, the goods can be received and temporarily stored in the sorting bin.

[0042] The sorting devices in related technologies are usually equipped with storage cavities with fixed positions and capacities. Such storage cavities have limitations in terms of accommodating and temporarily storing goods. For example, when the volume of goods is large or the sorting speed of the sorting device is too fast, goods are prone to pile up in the storage cavity.

[0043] To address the issue of goods piling up, sorting personnel need to promptly clean or replace the storage cavities. When sorting personnel intervene, the sorting equipment will pause operation, which will interrupt the sorting process and affect the sorting efficiency of the goods.

[0044] Based on the above-mentioned situation and problems, this application provides a sorting device with optimized and upgraded structure to meet the needs of large goods or high sorting speeds. In addition to a storage cavity, the sorting device also has an extra cavity. When the goods are large or the sorting speed is too fast, this extra cavity can accommodate and temporarily store the goods.

[0045] To achieve the above objectives, the sorting device is equipped with a retractable buffer cavity, which serves as an additional cavity. When goods accumulate or are about to accumulate in the storage cavity, the buffer cavity can extend and be positioned on one side of the storage cavity, allowing subsequent goods to be buffered in the buffer cavity. Once the accumulation of goods is alleviated, the buffer cavity can retract, allowing subsequent goods to re-enter the storage cavity, thus enabling the automatic sorting system to return to normal transportation and sorting status.

[0046] Considering structural dimensions and space occupancy, when the buffer cavity is retracted, it should be concealed as much as possible by the inherent structure of the sorting device. This ensures that the configuration of the buffer cavity does not affect the overall size of the sorting device. This inherent structure can be the aforementioned storage cavity, or it can be the sorting device or other parts of the automated sorting system.

[0047] It is understandable that the extension and retraction of the buffer cavity can be achieved in various ways. The buffer cavity can extend and retract along a straight line or along an arc.

[0048] Therefore, it is understood that the technical concept of this application embodiment is to add a buffer cavity on the basis of the storage cavity, and the buffer cavity has the function of extending and retracting, which can minimize the impact of setting the buffer cavity on the inherent structure of the compartment device.

[0049] Based on the above-mentioned grid device, this application embodiment also provides an automatic sorting system, which includes the above-mentioned grid device and has the advantage of high sorting efficiency.

[0050] An automated sorting system may include a sorting device, a sorting compartment device, and a control system. The sorting device may include a conveyor belt or a robotic arm or other conveying structure. The sorting compartment device is used to receive goods conveyed by the sorting device. The control system can control the sorting device to perform related actions or control the extension and retraction of the buffer cavities in the sorting compartment device.

[0051] Understandably, when the automated sorting system is operating at normal sorting speed, the control system primarily controls the sorting device to transport goods. When the goods are large or the sorting speed is too fast, the control system can also control the buffer cavity in the sorting device to extend based on the quantity, volume, or weight of the goods in the storage cavity. The sorting device can then transport subsequent goods into the buffer cavity, alleviating the accumulation of goods in the storage cavity and ensuring the continuous operation of the sorting process, thereby improving the sorting efficiency of the automated sorting system.

[0052] Figure 1A schematic diagram of a grid device according to an embodiment of this application is shown; Figure 2 This diagram shows a structural schematic of a grid device provided according to an embodiment of the present application from another angle.

[0053] In the embodiments of this application, please refer to Figure 1 and Figure 2 The compartment device includes a storage cavity 100 and a buffer cavity 200. The storage cavity 100 has a storage cavity 101 for storing goods, and the buffer cavity 200 has a buffer cavity 201 for storing goods.

[0054] The aforementioned buffer cavity 200 is a supplementary structure to the storage cavity 100. It is used to compensate for the insufficient space of the storage cavity 100 when the volume of the goods is large or the sorting speed is too fast, so that the sorting device can adapt to the continuous or high-speed operation of the sorting device.

[0055] The buffer cavity 200 can extend from one side of the storage cavity 100. Under normal circumstances, the buffer cavity 200 can be hidden in one side of the storage cavity 100 or in another location in the automated sorting system. When the sorting speed is too fast and the buffer cavity 200 needs to be used, the buffer cavity 200 can extend from one side of the storage cavity 100. This allows the sorting device to meet the usage requirements under normal and overload conditions, and under normal circumstances, it will not affect the inherent structure of the sorting device.

[0056] It should be noted that, in the above description, "normal situation" refers to the automatic sorting system operating at its normal speed, characterized by goods having a normal size and / or a normal sorting speed. The normal size and normal speed can be set according to actual conditions; for example, the normal size can have a certain range, and the normal speed can also have a certain range. On the other hand, "overload situation" refers to the accumulation of goods in the storage cavity 101 due to the large size of the goods or the excessively fast sorting speed.

[0057] In the following description of this application, the operating status of the grid device will be described primarily under normal and overload conditions.

[0058] In this embodiment of the application, the buffer cavity 201 is used to receive goods when the goods in the storage cavity 101 exceed a predetermined threshold.

[0059] The predetermined thresholds here can be set according to actual needs. For example, the predetermined threshold can be set based on the volume ratio of the storage cavity 101. Specifically, when the goods in the storage cavity 101 occupy more than 90% of the capacity of the storage cavity 101, it can be considered that the predetermined threshold has been exceeded. Alternatively, the predetermined threshold can be set based on the weight of the goods. Specifically, when the total weight of the goods in the storage cavity 101 exceeds 15 kilograms, it can be considered that the predetermined threshold has been exceeded. Furthermore, the predetermined threshold can be set based on the height of the goods in the storage cavity 101. Specifically, when the total height of the goods exceeds 90% of the height of the storage cavity 101, it can be considered that the predetermined threshold has been exceeded.

[0060] As mentioned above, when the goods do not exceed the predetermined threshold, the grid device is in normal condition; when the goods exceed the predetermined threshold, the grid device is in an overload condition.

[0061] It should be noted that the above-mentioned settings and values ​​of the predetermined thresholds are for illustrative purposes only. In actual situations, the predetermined thresholds can be set according to the type of goods being sorted, the volume of the storage cavity 100, etc.

[0062] Therefore, the compartment device in this application embodiment may include a monitoring structure 300 for monitoring the amount of goods in the storage cavity 101.

[0063] The monitoring structure 300 here may include at least one of a pressure sensor, a photoelectric sensor, a position sensor, and a camera. The pressure sensor may be located at the bottom of the storage cavity 101 to obtain the weight of the goods; the photoelectric sensor and / or position sensor may be located at the top of the storage cavity 101 to obtain the volume percentage or overall height of the goods; and the camera may be located at the top of the storage cavity 101 to obtain specific information about the goods.

[0064] In the aforementioned monitoring structure 300, the camera can be used in conjunction with at least one of a pressure sensor, a photoelectric sensor, and a position sensor, thereby improving the accuracy of monitoring.

[0065] In this embodiment, the buffer cavity 200 serves as a supplementary structure to the storage cavity 100, taking over the storage cavity 100's function of accommodating goods when the storage cavity 101 is overloaded. Specifically, when the goods in the storage cavity 101 exceed a predetermined threshold, it indicates that the sorting device is overloaded. At this time, the buffer cavity 200 extends from one side of the storage cavity 100 and receives the goods. The combination of the storage cavity 100 and the buffer cavity 200 in this embodiment can prevent interruptions in the sorting process, thereby improving the sorting efficiency of goods.

[0066] In some embodiments, please refer to Figure 1 and Figure 2The buffer cavity 200 is connected to the bottom of the storage cavity 100 and can extend from the bottom of the storage cavity 100.

[0067] By connecting the buffer cavity 200 to the bottom of the storage cavity 100, the buffer cavity 200 can be well hidden, and under normal circumstances, the shape of the compartment device will not be affected too much.

[0068] In other embodiments, the buffer cavity 200 may also be connected to other locations within the automated sorting system; for example, the buffer cavity 200 may be connected to a sorting device. This application does not impose excessive restrictions on the connection location of the buffer cavity 200.

[0069] In some other embodiments, the buffer cavity 200 may also extend from other sides of the storage cavity 100.

[0070] For ease of description and understanding, the following embodiments are mainly illustrated by taking the example of the buffer cavity 200 being connected to the bottom of the storage cavity 100 and being able to extend from the bottom of the storage cavity 100.

[0071] It should be noted that the buffer cavity 200 in this embodiment can be extended manually or automatically. When the former is used, the sorting device or automatic sorting system can be equipped with audible and visual alarm devices. For example, when the monitoring structure 300 detects that the goods in the storage cavity 101 exceed a predetermined threshold, the alarm device can generate audible and visual alarm information, allowing sorting personnel to push the buffer cavity 200 out from one side of the storage cavity 100. When the latter is used, the sorting device can be equipped with a control device (not shown in the figure) and a drive structure (not shown in the figure). The control device can be electrically connected to the control system of the automatic sorting system. This control device can control the drive structure based on the monitoring information from the monitoring structure 300, and drive the buffer cavity 200 to move.

[0072] In some embodiments, the grid device is configured with a drive structure, the output end of which is connected to the buffer cavity 200. The drive structure is used to drive the buffer cavity 200 to move. When the goods in the storage cavity 101 exceed a predetermined threshold, the drive structure is used to drive the buffer cavity 200 to extend from one side of the storage cavity 100.

[0073] The drive structure may include a drive unit, which may include components capable of outputting linear motion, such as cylinders, motors, and electric actuators. Furthermore, to facilitate the installation of the drive unit, the drive structure may also include a drive bracket, on which the drive unit can be mounted.

[0074] In some embodiments, a transmission structure, such as a gear set or a rack and pinion, may be provided between the drive structure and the buffer cavity 200. Its function is to ensure the effective transmission and stable transmission of motion, thereby improving the stability of the buffer cavity 200 during movement.

[0075] In an embodiment equipped with a control device and a drive structure, the operation of the grid device can be broadly described as follows: The monitoring structure 300 monitors the cargo information in the storage cavity 101. When the cargo exceeds a predetermined threshold, the control device transmits the cargo information to the control system. The control system issues a command and drives the drive structure to operate, which in turn drives the buffer cavity 200 to extend from one side of the storage cavity 100. Next, the cargo information in the storage cavity 101 is continuously monitored. When the cargo falls below the predetermined threshold and remains below it for a period of time, the control system controls the drive structure to retract the buffer cavity 200 back to its original position.

[0076] The following embodiments of this application mainly use a grid device with a driving structure as an example to describe the grid device in detail. Generally speaking, the driving structure can drive the buffer cavity 200 to move in a straight line, or the driving structure can drive the buffer cavity 200 to move in an arc. For ease of distinction and understanding, the former is the first type of embodiment, and the latter is the second type of embodiment.

[0077] In the first type of embodiment, please refer to Figure 1 and Figure 2 The storage cavity 100 is provided with a first guide rail pair 400 at the bottom, and the buffer cavity 200 is provided with a second guide rail pair (not shown in the figure) that cooperates with the first guide rail pair 400 at the top. The driving structure is used to drive the buffer cavity 200 and the second guide rail pair to move along the first guide rail pair 400.

[0078] The second guide rail pair can be embedded in or sleeved on the first guide rail pair 400, and the second guide rail pair can move along the first guide rail pair 400.

[0079] In the specific design, the first guide rail pair 400 can be connected to the bottom of the storage cavity 100 by welding or screws, and the second guide rail pair can be connected to the top of the buffer cavity 200 by welding or screws.

[0080] In some specific embodiments, the first guide rail pair 400 can be arranged in pairs, and the second guide rail pair can also be arranged in pairs, which can improve the smoothness of movement of the buffer cavity 200 and prevent the storage cavity 100 from deforming due to local stress.

[0081] In the first embodiment, a slide rail is provided at the bottom of the storage cavity 100, and a slider is provided at the top of the buffer cavity 200. The driving structure is used to drive the buffer cavity 200 and the slider to move along the slide rail.

[0082] The slide rail and the slider have a matching structure. For example, the slider can be nested on the slide rail. The movement of the buffer cavity 200 can be achieved through the nesting cooperation between the slider and the slide rail.

[0083] The specific structure of the slide rail and slider is not limited. The slider can be located on the outside of the buffer cavity 200 or on the inside of the buffer cavity 200.

[0084] In the second embodiment, a pivot can be provided at the bottom of the storage cavity 100, and the buffer cavity 200 is rotatably connected to the pivot. A driving structure is used to drive the buffer cavity 200 to rotate around the pivot.

[0085] The pivot can be located at the middle of the bottom of the storage cavity 100 or at the front of the bottom. Taking the front as an example, the buffer cavity 200 can be extended from the bottom of the storage cavity 100 by flipping or hidden in the bottom of the storage cavity 100 by flipping.

[0086] To facilitate the installation of the rotating shaft, a pair of lugs can be provided at the bottom of the storage cavity 100. The lugs have mounting holes, and the rotating shaft can be inserted into the mounting holes.

[0087] To fix the position of the buffer cavity 200, a first magnetic structure is provided on the storage cavity 100, and a second magnetic structure is provided on the buffer cavity 200. The second magnetic structure and the first magnetic structure are used to form a magnetic attraction so that the buffer cavity 200 is fixed in the designated position.

[0088] The aforementioned first and second magnetic structures enhance the structural stability of the sorting device in dynamic sorting environments, preventing goods from tipping over or device malfunctions caused by loose rotating shafts. Simultaneously, the rapid release function of the first and second magnetic structures (e.g., by de-energizing the electromagnet) allows the buffer cavity 200 to quickly rotate back to its retracted state after goods are removed, saving space and improving sorting efficiency. This technology, through a combination of physical adsorption and mechanical structure, solves the stability problem during the rotation process of the buffer cavity 200, ensuring the safety and reliability of the automated sorting system.

[0089] The specific number and location of the first magnetic structure can be set according to actual needs. It is understood that the magnetic attraction between the second magnetic structure and the first magnetic structure should be based on supporting the buffer cavity 200 and a certain weight of goods.

[0090] In some other embodiments, the position of the buffer cavity 200 can also be fixed by setting a locking mechanism, which can be a snap-fit ​​structure or an interlocking structure, etc.

[0091] In some embodiments, to accommodate different goods, multiple buffer cavities 200 can be provided, with multiple buffer cavities 200 located at the bottom of the storage cavity 100, and the volumes of the buffer cavities 201 of the multiple buffer cavities 200 being different.

[0092] During the operation of the automatic sorting system, the buffer cavity 200 can be selected reasonably according to the shape of the subsequent goods. For example, after the camera detects the shape information of the goods, the control system can control the corresponding buffer cavity 200 to extend from the bottom of the storage cavity 100.

[0093] In some embodiments, the grid device further includes an adaptive center of gravity adjustment structure, which includes a counterweight or a hydraulic damping mechanism for dynamically balancing the center of gravity position of the buffer box.

[0094] The center of gravity adjustment structure can prevent the buffer cavity 200 from tilting, thereby improving the stability of the buffer cavity 200 during the receiving of goods.

[0095] When the sorting device sorts goods to one side of the buffer cavity 200, the counterweight moves to the opposite side via a slide rail to balance the overall center of gravity; or the hydraulic damping mechanism absorbs the inertial force when the buffer cavity 200 starts and stops, reducing vibration. Its working principle is based on the principle of mechanical balance: the movement of the counterweight or the damping force of the hydraulic damping counteracts the torque generated by uneven distribution of goods, keeping the buffer cavity 200 stable during movement. This design effectively solves the structural vibration problem caused by the center of gravity shift in the buffer mechanism, preventing damage to goods due to shaking during sorting. Simultaneously, the damping force adjustment function of the hydraulic damping mechanism can automatically adjust according to the load changes in the buffer cavity 200, further improving the smoothness and safety of the device's operation. This technology, through dynamic balance design, significantly reduces the failure rate of the buffer mechanism, extends the service life of the equipment, and ensures the efficient operation of the sorting system.

[0096] In some embodiments, the grid device further includes an air blowing structure for blowing airflow toward the storage cavity 101 and / or the buffer cavity 201.

[0097] The air blowing structure can solve the cleaning problem of the storage cavity 100 and the buffer cavity 200, and can keep the inside of the storage cavity 101 and the buffer cavity 201 clean.

[0098] In specific settings, the air outlet structure may include an air blowing head and an air blowing pipe. The air blowing pipe may be connected to an external air source, such as an air pump or a blower.

[0099] In some embodiments, please refer to Figure 1The storage cavity 100 includes a support frame 110 and a grid-like enclosure 120 disposed on the support frame 110. The support frame 110 and the grid-like enclosure 120 enclose the storage cavity 101.

[0100] The aforementioned support frame 110 is a structural support for the storage cavity 100. It can be made of metal or rigid plastic. The mesh wall 120 can be made of metal mesh. The combination of the support frame 110 and the mesh wall 120 can reduce the weight of the storage cavity 100 while maintaining sufficient structural strength.

[0101] In some embodiments, please refer to Figure 1 and Figure 2 The compartment device may also include a support platform 500, a storage cavity 100 connected to the support platform 500, and a buffer cavity 200 connected to the bottom of the support platform 500, the buffer cavity 200 being able to extend from the bottom of the support platform 500.

[0102] The support platform 500 can improve the overall structural strength of the grid device, and the support platform 500 can serve as an intermediate connecting structure to connect the storage cavity 100 and the buffer cavity 200.

[0103] When the buffer cavity 200 is connected to the support platform 500, in order to enable the extension and retraction of the buffer cavity 200, the first guide rail pair 400 in the aforementioned embodiment can be set on the support platform 500 and the second guide rail pair can be set on the buffer cavity 200, or the slide rail in the aforementioned embodiment can be set on the support platform 500 and the slider or other structures can be set on the buffer cavity 200.

[0104] In addition, in some embodiments, please refer to Figure 1 and Figure 2 The bottom of the support platform 500 can also be provided with a support rod 600, and the buffer cavity 200 is inserted through the support rod 600, and the buffer cavity 200 can move along the support rod 600.

[0105] It is understandable that when the grid device is equipped with a drive structure, the output end of the drive structure can be connected to the buffer cavity 200, and the drive structure can drive the buffer cavity 200 to move along the support rod 600.

[0106] In addition, please refer to some specific embodiments. Figure 1 and Figure 2 The grid device also includes a locking member 700. The support rod 600 is provided with locking holes 601 at intervals. The locking member 700 is used to lock into the locking holes 601 and limit the position of the buffer cavity 200 on the support rod 600.

[0107] The position of the buffer cavity 200 can be restricted by the cooperation between the locking member 700 and the locking hole 601, so that the buffer cavity 200 is fixed after it is extended.

[0108] In some specific embodiments, there can be two locking members 700, which are respectively restricted on opposite sides of the buffer cavity 200, thereby improving the restriction effect on the buffer cavity 200.

[0109] In some specific embodiments, the locking member 700 includes a locking platform that can contact the support rod 600 to increase the contact area between the two, thereby ensuring the locking effect of the locking member 700.

[0110] Alternatively, the position of the buffer cavity 200 can be limited by providing a limiting part 610 on the support rod 600. The limiting part 610 can be a raised end 611 formed at the end of the support rod 600, or a bent part 612 formed on the support rod 600. The buffer cavity 200 can move between the bent part 612 and the raised end 611, and the bent part 612 and the raised end 611 are limited to the outside of the buffer cavity 200, thereby forming the movement stroke of the buffer cavity 200.

[0111] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0112] In the description of this application, it should be understood that the terms "comprising" and "having" and any variations thereof used in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0113] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly.
