Description

Technical Field

[0001] This invention belongs to the field of logistics sorting technology, and more specifically, relates to a dynamic docking device and method for sorting machines and cage carts. Background Technology

[0002] The logistics industry is rapidly developing towards large-scale and unmanned operations, and containerized transport has become the mainstream choice for mail transshipment due to its high efficiency and compactness. Cage trucks, as containerized containers, are widely used in mail containerization operations at sorting sites due to their large volume, regular structure, and compatibility with various automated equipment.

[0003] Currently, the docking methods between sorting machines and cage carts in the industry are mainly divided into two categories. One is the manual handling and stacking method, where after the mail is sorted by the sorting machine, it falls into the chute, and the operator needs to manually carry the mail from the chute to the cage cart one by one and manually stack it neatly. After the cage cart is full, it is transferred to the next stage. The other is the static docking and manual adjustment method, where the cage cart is fixedly parked below the chute outlet of the sorting machine, and the sorted mail falls directly into the cage cart through the chute. When the mail accumulates on one side of the cage cart, the operator needs to manually push the cage cart to adjust its parking position so that the area of ​​the cage cart that is not full is aligned with the chute outlet before continuing the loading operation. However, manual handling and stacking requires a lot of manpower, is time-consuming and labor-intensive, and does not conform to the trend of automation in the industry. When using cage carts, the drop height difference of the mail from the chute outlet into the cage cart is large, which can easily lead to damage to the mail. At the same time, the mail drop trajectory is fixed, which can easily cause accumulation on one side of the cage cart, resulting in uneven use of the cage cart space, low actual loading rate, and subsequent manual reorganization, which further increases the workload. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a dynamic docking device and method for sorting machines and cage carts. This solves the technical problem in the prior art where traditional docking devices fix the cage cart below the sorting machine chute outlet, resulting in a fixed mail drop trajectory, which easily leads to accumulation on one side of the cage cart, causing uneven use of the cage cart space and requiring manual secondary sorting.

[0005] The purpose and effectiveness of the dynamic docking device and method for sorting machines and cage carts of the present invention are achieved by the following specific technical means: A dynamic docking device for a sorting machine and a cage car includes a gantry mounted on the sorting machine, and a tilting component rotatably mounted on one side of the gantry for adjusting the angle of the cage car.

The fork assembly includes a lifting frame, a lifting frame slidably disposed on one side of the tilting frame, a second push rod structure disposed on the tilting frame, and the top end of the second push rod structure being connected to the lifting frame via a chain.

[0006] According to a preferred embodiment, a spindle fixing seat is provided on the top of the gantry, and a spindle is mounted on the spindle fixing seat by a spindle pressure block; The flipping assembly also includes a flipping motor, which is installed on the first push rod structure.

[0010] According to a preferred embodiment, the flipping frame is provided with two sets of slide rail base plates on one side, and two sets of slide rails are respectively provided on one side of the two sets of slide rail base plates. The lifting frame is provided with two sets of sliders on one side, and the two sets of sliders are slidably connected to the two sets of slide rails respectively. The bottom of the lifting frame is equipped with two sets of fork arms for supporting the cage truck.

[0011] A dynamic docking method for a sorting machine and a cage cart, applied to the aforementioned dynamic docking device for a sorting machine and a cage cart, is characterized by comprising the following steps: S1: Place the cage car on the fork assembly and lift it to the preset height. Based on the tilting assembly, tilt the cage car to ° and dock it with the slide transition plate. S2: Based on the preset communication link, obtain the sorting machine's drop parameters, mail size and weight data, and at the same time scan the cage car's position to obtain the remaining space distribution data of the cage car; S3: Based on the sorting machine's drop parameters, mail size and weight data, and the remaining space distribution data of the cage car, simulate and predict mail dropping into the cage. Based on the preset visual inspection equipment, capture the real-time stacking status of mail in the cage car to obtain the cage car loading status data. S4: Adjust the cage car's position and orientation based on the simulation data of the mail dropping cage and the cage car loading status data; S5: Based on the visual inspection equipment and spatial sensors, the full cage signal of the cage car is obtained. Based on the full cage signal, the fork assembly and the tilting assembly are reset, and the full cage car is transferred to the loading area by automatic handling equipment or manual labor.

[0012] According to a preferred embodiment, adjusting the cage car's posture based on mail dropping simulation data and cage car loading status data includes: Based on the comparison of the predicted mail drop area and the loading status data of the cage truck, the overlap area between the predicted mail drop area coordinates and the planned drop area is used to determine whether it is less than a set threshold. When the overlap area is less than the set threshold, the height and angle of the cage truck are adjusted by the fork assembly and the tilting assembly to guide the mail to fall into the target area. Based on the loading status data of the cage car, it can identify whether there is an undesirable mail stacking situation inside the cage car. When an undesirable mail stacking situation occurs, the cage car is shaken by the fork assembly and the tilting assembly to break the undesirable mail stacking situation.

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but should not be used to limit the scope of protection of the present invention. Example

[0018] As attached Figures 1 to 6 As shown: This invention provides a dynamic docking device for a sorting machine and a cage cart, including a gantry 101 mounted on the sorting machine. A tilting assembly for adjusting the angle of the cage cart is rotatably mounted on one side of the gantry 101. The tilting assembly includes a tilting frame 102, with one side of the gantry 101 rotatably connected to the tilting frame 102. A first push rod structure 103 is also mounted on the gantry 101. One side of the first push rod structure 103 is rotatably connected to the tilting frame 102 via a push rod 104. In use, the first push rod structure 103 can drive the push rod 104 to move towards the tilting frame 102. The push rod 104 then pushes the tilting frame 102 to rotate around its rotatable connection point with the gantry 101, thereby adjusting the angle of the cage cart so that the cage cart inlet can dock with the chute transition plate of the sorting machine, thus tilting the cage cart. A fork assembly for lifting and lowering the cage cart is slidably mounted on one side of the frame 102. The fork assembly includes a lifting frame 201. A lifting frame 201 is slidably mounted on one side of the tilting frame 102. A second push rod structure 202 is mounted on the tilting frame 102. The top of the second push rod structure 202 is connected to the lifting frame 201 via a chain 203. In use, the second push rod structure 202 can drive the chain 203 to move. The chain 203 then pulls or releases the lifting frame 201, causing the lifting frame 201 to move up and down along the sliding direction of the tilting frame 102. This causes the cage cart placed on the lifting frame 201 to adjust its height, providing sufficient operating space for the angle adjustment of the cage cart. At the same time, the angle adjustment changes the trajectory of the mail, preventing the mail from accumulating on one side of the cage cart.

[0019] A spindle fixing seat 105 is provided on the top of the gantry 101. A spindle 107 is installed on the spindle fixing seat 105 via a spindle pressure block 106. The spindle pressure block 106 can fix the spindle 107 to prevent the spindle 107 from loosening or shifting during the operation of the device, ensuring that the spindle 107 provides a stable support foundation for the rotation of the tilting frame 102. The tilting assembly also includes a tilting motor 108. The tilting motor 108 is provided on the first push rod structure 103. The tilting motor 108 provides power support for the extension and retraction of the first push rod structure 103. A tilting support 109 is provided on the side of the tilting frame 102 away from the lifting frame 201. The connector at one end of the push rod 104 is rotatably connected to the tilting support 109. When the first push rod 104... A push rod structure 103 drives a push rod 104 to move toward the tilting frame 102. The push rod 104 can push the tilting frame 102 through the tilting support 109, causing the tilting frame 102 to rotate around the spindle 107, thereby adjusting the angle of the cage car. Two sets of first bearing seats 110 are provided on the gantry 101. A motor hinge seat 111 is rotatably hinged between the two sets of first bearing seats 110. The first push rod structure 103 is installed on the motor hinge seat 111. The motor hinge seat 111 can rotate around the first bearing seat 110, so that the first push rod structure 103 can adjust its own installation angle during the process of driving the tilting frame 102 to rotate, avoiding structural interference and ensuring the smooth operation of the entire tilting action.

[0020] Please refer to, for example Figure 5 and Figure 6As shown, the fork assembly also includes a lifting motor 204, which is mounted on the second push rod structure 202. The lifting motor 204 provides power support for the extension and retraction of the second push rod structure 202. A motor support plate 205 is provided on the tilting frame 102, and the second push rod structure 202 is mounted on the top of the motor support plate 205. The motor support plate 205 provides a stable mounting support base for the second push rod structure 202, preventing the second push rod structure 202 from shaking or shifting during operation. One end of the chain 203 is provided with a chain connecting block 206, which is mounted on the top of the push rod of the second push rod structure 202. A chain pull block 207 is welded to the top of the lifting frame 201, and the other end of the chain 203 is connected to the chain pull block 207. A chain wheel 209 is mounted on the spindle 107 through a synchronous pulley locking sleeve 208, and the chain 203 is wound around the circumference of the chain wheel 209. During use, the second push rod structure... The extension and retraction of push rod 202 drives one end of chain 203 to move synchronously through chain connecting block 206. Chain wheel 209 can change the direction of force on chain 203, causing the other end of chain 203 to pull chain pull block 207, thereby driving lifting frame 201 to move up and down along tilting frame 102. Synchronous pulley locking sleeve 208 can fix chain wheel 209 in a designated position on spindle 107 to prevent chain wheel 209 from shifting and affecting chain transmission effect. Two sets of bearing mounting plates 210 are provided on one side of tilting frame 102. Each set of bearing mounting plates 210 is provided with a second bearing seat 211 on one side. The second bearing seat 211 is rotatably connected to spindle 107. Bearing mounting plate 210 provides installation position for second bearing seat 211. Second bearing seat 211 can reduce frictional resistance when spindle 107 rotates, ensuring that spindle 107 drives chain wheel 209 to rotate smoothly, thereby ensuring the stability of chain 203 transmission process.

[0021] Two sets of slide rail base plates 212 are provided on one side of the flipping frame 102. The two sets of slide rail base plates 212 provide a stable installation base for the slide rails 213. Two sets of slide rails 213 are respectively provided on one side of the two sets of slide rail base plates 212. Two sets of sliders 214 are provided on one side of the lifting frame 201. The two sets of sliders 214 are slidably connected to the two sets of slide rails 213 respectively. In use, the sliders 214 can slide smoothly along the extension direction of the slide rails 213, thereby guiding the lifting frame 201 to perform stable lifting and lowering movements, avoiding tilting or deviation of the lifting frame 201 during movement. Two sets of fork arms 215 for supporting the cage cart are provided at the bottom of the lifting frame 201. The fork arms 215 can extend under the support structure at the bottom of the cage cart to lift the cage cart smoothly. The height position of the cage cart can be adjusted in conjunction with the lifting and lowering movements of the lifting frame 201. At the same time, the angle of the cage cart can be adjusted with the rotation of the flipping frame 102 to meet the usage requirements of the cage cart docking with the sorting machine chute transition plate, and to ensure the uniform falling of subsequent mail into the cage.

[0022] Please see as follows Figure 7As shown, the present invention also provides a dynamic docking method for a sorting machine and a cage car, applied to the above-mentioned dynamic docking device for a sorting machine and a cage car, comprising the following steps: S1: Place the cage car on the fork assembly and lift it to the preset height. The cage car is then flipped over by the flipping assembly and diagonally docked with the slide transition plate.

[0023] Specifically, the empty cage car is placed smoothly on the two sets of fork arms 215 at the bottom of the lifting frame 201, ensuring that the bottom of the cage car is completely in contact with the fork arms 215. The lifting motor 204 installed on the second push rod structure 202 is started. The lifting motor 204 drives the push rod of the second push rod structure 202 to move down. The top of the push rod of the second push rod structure 202 drives one end of the chain 203 to move synchronously through the chain connecting block 206. The chain 203 is wrapped around the sprocket 209 to change the direction of force, thereby pulling the chain pull block 207 on one side of the lifting frame 201, and driving the lifting frame 201 to move along the tilting frame 1 via the slider 214. The sliding rail 213 on one side of 02 slides upward until the cage car is raised to a preset height, leaving sufficient operating space for the subsequent cage car flipping action. Then, the flipping motor 108 installed on the first push rod structure 103 is started. The flipping motor 108 drives the first push rod structure 103 to move the push rod 104 toward the flipping frame 102. The connector at one end of the push rod 104 pushes the flipping support 109 on one side of the flipping frame 102, causing the flipping frame 102 to rotate around the spindle 107 until the cage car is flipped and tilted, so that the cage car inlet is precisely connected with the chute transition plate of the sorting machine, preparing for the subsequent mail to fall into the cage.

[0024] S2: Based on the preset communication link, acquire sorting machine drop parameters, mail size and weight data, and at the same time scan the cage car position to acquire cage car remaining space distribution data.

[0025] In this embodiment, the sorting machine transmits drop parameters, mail size and weight data based on a preset communication link. These data can intuitively reflect the basic attributes and drop patterns of the mail, providing a basis for subsequent mail drop simulation calculations. At the same time, the vision inspection device is activated to perform an all-round scan of the cage placed on the fork arm 215, capturing the current angle, height and pose information of the cage. Combined with image recognition technology, the space occupancy in the cage is analyzed to clarify the distribution range of the loaded area and the idle area in the cage, and then the remaining space distribution data of the cage is generated.

[0026] S3: Based on the sorting machine's drop parameters, mail size and weight data, and the remaining space distribution data of the cage car, simulate and predict mail dropping into the cage. Based on the preset visual inspection equipment, capture the real-time stacking status of mail in the cage car to obtain the cage car loading status data.

[0027] In this embodiment, the sorting machine's drop parameters, mail size and weight data, and cage car's remaining space distribution data are input into the system's preset simulation model. Based on the mail's size and weight, the trajectory of the mail falling from the chute transition plate into the cage car is simulated. Combined with the current remaining space distribution of the cage car, the expected cage-fall coordinates of the mail are calculated, thereby completing the simulated prediction of mail falling into the cage and clarifying the approximate position of the mail after falling into the cage car. At the same time, a preset visual inspection device is activated to continuously photograph the inside of the cage car, capturing the real-time stacking position, stacking height, and space occupancy of the mail inside the cage car. The captured image information is converted into data information and integrated to generate cage car loading status data, providing accurate data support for subsequent judgments on whether the mail is unilaterally stacked and whether the cage car's posture needs to be adjusted.

[0028] S4: Adjust the cage car's position and orientation based on the simulated data of the mail dropping and the loading status data of the cage car.

[0029] In this embodiment, the overlap area between the predicted mail drop coordinates and the planned drop location is compared with the mail cage loading status data to determine if it is less than a set threshold. When the overlap area is less than the set threshold, the lifting motor 204 of the fork assembly is activated to drive the second push rod structure 202. The second push rod structure 202 drives the lifting frame 201 to rise and fall along the sliding rail 213 of the tilting frame 102 via the chain 203, thereby adjusting the height of the car carrier. At the same time, the tilting motor 108 of the tilting assembly is activated to drive the first push rod structure 103. The first push rod structure 103 drives the tilting frame 102 via the push rod 104. Rotating around the spindle 107 adjusts the angle of the cage car. By coordinating the adjustment of height and angle, the position of the cage car is changed, guiding the mail to fall into the idle target area of ​​the cage car, avoiding the accumulation of mail on one side of the cage car. Based on the loading status data of the cage car, it identifies whether there is an undesirable stacking situation of mail tilting or excessively high local areas in the cage car. When an undesirable mail stacking situation occurs, the fork assembly is controlled to drive the cage car to lift slightly, while the tilting assembly is controlled to drive the cage car to rotate back and forth at a small angle. Through the coordinated action of the fork assembly and the tilting assembly, the cage car is shaken, breaking the undesirable mail stacking state and making the mail more evenly distributed in the cage car.

[0030] S5: Based on the visual inspection equipment and spatial sensors, the full cage signal of the cage car is obtained. Based on the full cage signal, the fork assembly and the tilting assembly are reset, and the full cage car is transferred to the loading area by automatic handling equipment or manual labor.

[0031] Specifically, the system continuously monitors the interior of the cage car using a vision inspection device and a space sensor. The vision inspection device captures the stacking height of mail and the overall space occupancy within the cage car, while the space sensor simultaneously detects the remaining space within the cage car. The system integrates and analyzes these two types of data. When the system determines that the cage car has reached a full load state, it generates and sends a full cage signal. Based on the full cage signal, the system initiates the reset procedure for the fork assembly and the tilting assembly. First, the tilting motor 108 drives the first push rod structure 103 to operate. The first push rod structure 103 drives the tilting frame 102 to rotate in the opposite direction around the spindle 107 via the push rod 104 until the tilting frame... Once frame 102 returns to its initial horizontal position, the lifting motor 204 is activated to drive the second push rod structure 202. The second push rod structure 202 drives the lifting frame 201 to slide downwards along the sliding rail 213 via the chain 203 until the cage car on the fork arm 215 smoothly contacts the ground, completing the reset operation of the fork assembly. Subsequently, the full cage car is removed from the fork arm 215 by fork-type automated handling equipment or manually and transferred to the unmanned vehicle loading area. At this time, the entire docking device returns to its initial standby state and can receive the next empty cage car to carry out a new round of docking and loading operations, ensuring the continuity of the sorting and containerization process.

[0032] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.

Based on the full cage signal, the fork assembly and the tilting assembly are reset, and the full cage car is transferred to the loading area by automatic handling equipment or manual labor.

8. The dynamic docking device for a sorting machine and a cage car according to claim 7, characterized in that: The adjustment of the cage car's position and orientation based on the simulated data of the mail dropping and the loading status data of the cage car includes: Based on the comparison of the predicted mail drop area and the loading status data of the cage truck, the overlap area between the predicted mail drop area coordinates and the planned drop area is used to determine whether it is less than a set threshold. When the overlap area is less than the set threshold, the height and angle of the cage truck are adjusted by the fork assembly and the tilting assembly to guide the mail to fall into the target area. Based on the loading status data of the cage car, it can identify whether there is an undesirable mail stacking situation inside the cage car. When an undesirable mail stacking situation occurs, the cage car is shaken by the fork assembly and the tilting assembly to break the undesirable mail stacking situation.
