[0048] Example 1

[0049] like Figure 1 - Figure 5 As shown, the transportation system proposed in Embodiment 1 of the present invention includes: a conveying device 1, a single-piece separation device 2, a sorting device 3, and a palletizing device 4;

[0050] Conveying device 1, single-piece separation device 2 and sorting device 3 are connected in sequence, and palletizing device 4 is located at the output end of sorting device 3;

[0051] The conveying device 1 is used to convey materials to the single-piece separation device 2. The single-piece separation device 2 is used to sort the materials and convey them to the sorting device 3. The sorting device 3 is used to sort the materials and convey the sorted materials to the palletizing device 4.

[0052] Specifically, the conveying device 1 is used to transport materials to the single-piece separation device 2. The conveying device 1 can be a belt conveyor, mesh belt conveyor, roller conveyor, steel belt conveyor, chain conveyor, chain plate conveyor, telescopic conveyor, or double-speed chain conveyor, etc., as long as it can transport materials. The output end of the conveying device 1 has the single-piece separation device 2, and the two are in close contact.

[0053] The single-piece separation device 2 is used to sort the conveyed materials and transport the sorted materials to the sorting device 3. The output end of the single-piece separation device 2 is connected to the sorting device 3, and the two are in close contact.

[0054] The sorting device 3 is used to sort the sorted materials.

[0056] The transportation system provided in this application embodiment transports materials to a single-piece separation device 2 via a conveying device 1. The single-piece separation device 2 sorts the transported materials and then transports the sorted materials to a sorting device 3. Under the action of the sorting device 3, the materials are sorted, and the sorted materials are transported to a palletizing device 4 for stacking and classification. This structural design not only improves the transportation efficiency of chilled food before loading, but also avoids the phenomenon of thawing and melting of chilled food due to excessive time spent during the unloading and loading process, thus preventing secondary contamination of chilled food during transportation. This ensures food safety while reducing the number of personnel required for transportation and sorting, saving time and effort.

[0057] Reference Appendix Figure 1 and appendix Figure 4 - Figure 5 In a specific implementation, the conveying device 1 includes: a support frame, a drive unit, at least two conveying sections 11 and at least one splitting section 12;

[0058] Both the conveying section 11 and the splitting section 12 are mounted on a support frame. A splitting section 12 is provided between two adjacent conveying sections 11, and the splitting section 12 is connected to the conveying sections 11 on both sides respectively. The conveying section 11 includes a driving drum 111, a driven drum 112, and a first conveyor belt 113. The driving drum 111 and the driven drum 112 are spaced apart on the support frame and are rotatably connected to the support frame respectively. The first conveyor belt 113 is wound between the driving drum 111 and the driven drum 112. The splitting section 12 includes a second conveyor belt 121, two first drums 122, and a second drum 123. The two first drums 122 are spaced apart on the support frame and are rotatably connected to the support frame respectively. The second drum 123 is located above the two first drums 122 and is rotatably connected to the support frame. The second conveyor belt 121 is wound between the two first drums 122 and the second drum 123. Both the conveying section 11 and the splitting section 12 are driven by a drive unit, which is a synchronous motor.

[0059] The support frame supports and secures the drive unit, conveying section 11, and splitting section 12. The support frame is detachably connected to these components, facilitating future maintenance. The drive unit provides power to the conveying section 11 and splitting section 12, enabling their operation and use. The conveying section 11 transports materials; the section on one side of the splitting section 12 transports materials to it, while the section on the other side transports the de-stacked materials to the single-piece separation device 2. The splitting section 12 de-stacks the stacked materials. The number of splitting sections 12 can be one or more; this application does not limit the number. Technicians can select an appropriate number of splitting sections 12 based on actual needs to achieve the best de-stacking effect. The output end of one conveying section 11 has a splitting section 12, and the output end of the splitting section 12 has another conveying section 11. The conveying section 11, the splitting section 12, and the other conveying section 11 are in a close contact relationship. The drive unit can be a motor.

[0060] This application provides an embodiment of a conveying section 11, which includes a driving drum 111, a driven drum 112, and a first conveyor belt 113. The driving drum 111 and the driven drum 112 are rotatably connected to a support frame via shafts and bearings, and are spaced apart. The driving drum 111 and the driven drum 112 are equidistant from the bearing surface, meaning they are located in the same plane. The bearing surface is the ground. The first conveyor belt 113 is wound around the driving drum 111 and the driven drum 112 and is taut. The first conveyor belt 113 is used to convey materials. A synchronous motor can be driven and connected to either the driving drum 111 or the driven drum 112; those skilled in the art can choose according to actual needs, and this application does not impose any limitations. The synchronous motor drives the active drum 111 or the driven drum 112 to rotate. Under the action of the first transmission belt, the driven drum 112 or the active drum 111 moves accordingly, thereby realizing the effect of the first transmission belt transporting materials.

[0061] This application provides an embodiment of a split segment 12, which includes a second conveyor belt 121, two first rotating drums 122, and a second rotating drum 123. The first rotating drums 122 and the second rotating drum 123 are rotatably connected to a support frame via shafts and bearings. There is a gap between the two first rotating drums 122, and the distance between the two first rotating drums 122 and the bearing surface is the same, that is, the two first rotating drums 122 are located in the same plane. The distance between the second rotating drum 123 and the bearing surface is greater than the distance between the two second rotating drums 123 and the bearing surface, that is, the second rotating drum 123 is located above the two first rotating drums 122. A second conveyor belt 121 is wound between the second rotating drum 123 and the two first rotating drums 122, and the second conveyor belt 121 is taut. The second conveyor belt 121 is used to de-stack the stacked materials. When the stacked materials move in the splitting section 12, due to the height difference of the splitting section 12, the stacked materials move in a manner equivalent to climbing an incline. Under the action of gravity, the stacked materials begin to separate, thereby achieving the de-stacking effect. The synchronous motor can be driven and connected to either of the two first rotating drums 122 or the second rotating drum 123. Technicians can choose according to actual needs, and this application does not impose any limitations. The synchronous motor drives either of the two first rotating drums 122 or the driven rotating drum 112 to rotate. Under the action of the second transmission belt, the other of the two first rotating drums 122 and the driven rotating drum 112 or both first rotating drums 122 move together, thereby achieving the effect of transporting and de-stacking materials by the second transmission belt.

[0062] In order to ensure that the conveying section 11 and the splitting section 12 operate synchronously, the drive unit in this application is preferably a synchronous motor. The specific connection method and program settings between the synchronous motor and the conveying section 11 and the splitting section 12 are known to those skilled in the art and will not be described in detail here.

[0063] Reference Appendix Figure 1 - Figure 2 In specific implementation, the single-piece separation device 2 includes:

[0064] A separating belt conveyor and a scattering belt conveyor are connected in sequence, and a visual recognition module is installed above the separating belt conveyor and the scattering belt conveyor.

[0065] Specifically, this application provides an embodiment of a single-piece separation device 2, which includes a separation belt conveyor and a scattering belt conveyor connected in sequence. The single-piece separation device 2 is prior art and can be obtained through procurement.

[0066] The main function of the single-item separation device 2 is to automatically separate, space, and intelligently queue bundled packages before they enter various automated sorting lines. This transforms disordered packages into orderly single-row "arrays" at specified intervals, allowing them to pass through the DWS and various automated sorting equipment in sequence. This significantly improves the success rate and accuracy of package sorting. After the goods are separated by the scattering conveyor belt, they enter the separating conveyor belt. Simultaneously, the vision recognition system captures the real-time position of the goods, and the optimal separation sequence and path are calculated through data algorithm analysis. Finally, the separating conveyor belt separates, spaces, and queues the goods and packages.

[0067] Reference Appendix Figure 1 and Figure 3 In specific implementation, the sorting device 3 includes:

[0068] The sorting pendulum machine and the sorting conveyor are connected to the sorting pendulum machine and the palletizing device 4, respectively.

[0069] Specifically, this application provides an embodiment of a sorting device 3, wherein the sorting device 3 is a pendulum-type automated sorting equipment, which includes a sorting pendulum machine and a sorting conveyor mechanism. The sorting device 3 is prior art and can be obtained through procurement.

[0070] The swing wheel sorting machine mainly consists of a conveyor device 1 (rollers and a swing wheel sorting machine belt), a synchronous steering controller, a transmission device, and a frame. During operation, based on instructions and information recognition from the management system, the steering controller changes the running direction of the conveyor device 1, enabling sorting of items on the left and right sides and transporting them to the diversion conveyor. Also known as a swing wheel automated sorting device, the swing wheel sorting machine uses 45-degree and 90-degree steering conveying methods. The grid positions are matched with a "swing wheel matrix." Packages are transported on the main conveyor, and upon reaching the target grid, the servo motor controls the steering of the swing wheels to change the path of the packages, achieving the sorting purpose. The sorting speed is 4000 pieces / hour, supporting automatic barcode scanning, automatic weighing, and automatic measurement of goods dimensions. It boasts stable performance, flexible configuration, and can be customized according to user needs. It supports seamless connection with various hardware components and communication with a host computer, maintaining stable speed.

[0071] It should be noted that workers are stationed on both sides of the conveyor mechanism of the sorting device 3. When the de-stacked materials pass through the single-piece separation device 2, the single-piece separation device 2 sorts the de-stacked materials and conveys the sorted materials to the sorting device 3. Before the sorted materials reach the "swing wheel matrix", the workers manually affix codes to the sorted materials and place the coded materials back onto the conveyor mechanism of the sorting device 3. The conveyor mechanism transports the coded materials to the location of the barcode scanner for identification. After identification, the conveyor mechanism transports the coded materials to the corresponding sorting port and enters the sorting port under the action of the "swing wheel matrix", achieving the effect of classification and sorting. The specific system program settings and classification requirements can be selected by technicians according to the actual situation, and this application does not impose any restrictions.

[0072] Reference Appendix Figure 1 In specific implementation, the palletizing device 4 includes a stacking robot arm; wherein, the output end of each sorting and conveying mechanism is equipped with a stacking robot arm.

[0073] Specifically, this application provides an embodiment of a palletizing device 4, wherein the palletizing device 4 includes a stacking robotic arm. The stacking robotic arm is prior art and can be obtained through procurement.

[0074] The stacking robot arm mainly consists of three parts: the actuator, the drive mechanism, and the control mechanism. It is a multi-degree-of-freedom fully automatic robotic palletizer, primarily composed of four joints capable of four types of motion: base rotation, forward and backward and up and down movement of the linkage-structured arm, wrist rotation, and extension and gripping movements of the gripper, all driven by AC servo motors. The actuator of the stacking robot arm mainly consists of the hand, arm, and torso, primarily guiding the robot's fingers to accurately grasp objects and transport them to the required position. The drive mechanisms are mainly of three types: hydraulic drive, pneumatic drive, and electric motor drive.

[0075] Each sorting and conveying mechanism is equipped with a stacking robot arm at its output end. This design facilitates the stacking robot arm in stacking and classifying the sorted materials.

[0076] Reference Appendix Figure 5 Furthermore, it also includes: a material feeding device 5;

[0077] The material discharge device 5 is located above the input end of the conveying device 1; wherein, the material discharge device 5 is used to centrally discharge materials to the conveying device 1.

[0078] Specifically, the material discharge device 5 is used to centrally discharge materials to the conveying device 1. This structural design can improve the material transportation efficiency and enhance the efficiency of the system in unloading materials at the dock.

[0079] Reference Appendix Figure 5In specific implementation, the material feeding device 5 includes: a support 51 and a feeding hopper 52;

[0080] The support 51 places the hopper 52 on the input end of the conveying device 1, and the discharge port of the hopper 52 is located above the input end of the conveying device 1. The end of the hopper 52 away from the discharge port is the inlet. The area enclosed by the cross-section of the hopper 52 gradually decreases along the direction from the inlet to the outlet.

[0081] Specifically, this application provides an embodiment of a material feeding device 5, which includes a support 51 and a feeding hopper 52. The support 51 is used to support and fix the feeding hopper 52. The support 51 and the feeding hopper 52 can be connected by a fixed connection or by a detachable connection, such as by bolt connection or welding. To facilitate the later maintenance of the device, the support 51 and the feeding hopper 52 are preferably connected by a detachable connection, i.e., by bolt connection. The discharge port of the feeding hopper 52 is located above the input end of the conveying device 1, and the end of the feeding hopper 52 opposite to the discharge port is the inlet. The area enclosed by the cross-section of the feeding hopper 52 gradually decreases from the inlet to the discharge port. This structural design allows the material entering the feeding hopper 52 to fall accurately onto the conveying device 1, facilitating the subsequent process flow of sorting, classifying, and categorizing the material.

[0082] Reference Appendix Figure 1 Furthermore, it also includes: crane 6;

[0083] Crane 6 is used to lift materials and transport them through the feed inlet to the discharge hopper 52.

[0084] Specifically, crane 6 is existing technology and can be obtained through procurement.

[0085] Reference Appendix Figure 1 Furthermore, it also includes: forklift 7;

[0086] Forklift 7 is used to transport materials sorted by the stacking robot arm.

[0087] Specifically, forklift 7 is existing technology and can be purchased. The stacking robot arm uses wooden rafts to stack the sorted materials. That is, the sorted materials are placed on the wooden rafts and stacked under the action of the stacking robot arm. Forklift 7 moves the wooden rafts to transport the sorted materials. Forklift 7 then transfers the sorted materials from the stacking robot arm to a truck, which then transports the sorted materials.

[0091] S2. The conveying device transports the material to the single-piece separation device, and sorts and transports the material through the single-piece separation device so that the sorted material is transported to the sorting device.

[0092] S3. The material after being transported is sorted by the sorting device, and the sorted material is then transported to the palletizing device.

[0093] S4. The palletizing device categorizes materials according to their sorted types.

[0094] Specifically, the loading and unloading process in this embodiment two can directly use the transportation system provided in the above embodiment one. For the specific implementation structure, please refer to the relevant content described in the above embodiment one, which will not be repeated here.

[0095] In the technical solution of this application embodiment, the material is conveyed to the single-piece separation device through a conveying device. The single-piece separation device sorts the conveyed material and then conveys the sorted material to the sorting device. Under the action of the sorting device, the material is sorted and then conveyed to the palletizing device for stacking and classification. This structural design not only improves the transportation efficiency of chilled food before loading, but also avoids the phenomenon of thawing and melting of chilled food due to excessive time consumption during the unloading and loading process, thus preventing secondary contamination of chilled food during transportation. This ensures food safety while reducing the number of personnel required in the transportation and sorting process, saving time and effort.
