[0062] In the following, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings, which show representative embodiments of the present application and are not intended to limit the present application.

[0063] The present application provides a conveying device.

[0064] Please refer to Figure 1The conveying device 1 is used for container 110 production. The conveying device 1 comprises a first conveying assembly 11 and a second conveying assembly 21. Specifically, the first conveying assembly 11 is arranged along a first horizontal direction D1. The second conveying assembly 21 is arranged along a second horizontal direction D2 and connected to the first conveying assembly 11. The first conveying assembly 11 has a bearing surface 11a, and the bearing surface 11a is formed with first stations 11b for bearing containers 110 moving along the first horizontal direction D1. The number of first stations 11b is at least two, and adjacent first stations 11b are arranged along the first horizontal direction D1. Further, the bearing surface 11a is further formed with second stations 11c, which are located at least on one side of the first stations 11b along the first horizontal direction D1. The second stations 11c are provided with support plates 13 to bear workers 130 moving synchronously with the containers 110 at the first stations 11b and working on the containers 110.

[0065] According to the conveying device of the present embodiment, the workers 130 are borne by the second stations 11c, which can ensure the safety of the workers 130, and the workers 130 at the second stations 11c can move synchronously with the containers 110 at the first stations 11b, which can ensure the quality and efficiency of the work and reduce the physical consumption of the workers 130.

[0066] Preferably, the support plates 13 extend a predetermined height in a direction perpendicular to the bearing surface 11a. In other words, the support plates 13 protrude upward from the bearing surface 11a. In this way, the bottom surface of the containers 110 at the first stations 11b is lower than the top surface of the support plates 13, that is, there is a height difference between the position of the workers 130 and the bottom surface of the containers 110. When the conveying device 1 is in operation, if it suddenly stops or other faults occur, the support plates 13 have a certain blocking effect on the containers 110, which can prevent the containers 110 from hitting the workers 130 and ensure the safety of the workers 130.

[0067] Please refer to Figure 1 and Figure 2 , along the first horizontal direction D1, the number of second conveying assemblies 21 is at least two and spaced from each other. It should be noted that among the at least two second conveying assemblies 21, at least one second conveying assembly 21 is a moving-in assembly, and at least one second conveying assembly 21 is a moving-out assembly. For example Figure 1 and Figure 2 , along the first horizontal direction D1, the number of second conveying assemblies 21 is two, and the two second conveying assemblies 21 are spaced along the first horizontal direction D1. It can be understood that the moving-in assembly is used to move the containers 110 into the first conveying assembly 11, and the moving-out assembly is used to move the containers 110 out of the first conveying assembly 11. Figure 1The arrows in the figure show the direction of the flow of the container 110, wherein the second conveying assembly 21 located below the drawing is configured as an incoming assembly, and the second conveying assembly 21 located above the drawing is configured as an outgoing assembly. In other words, Figure 1 Or Figure 2 In the figure, along the first horizontal direction D1, two ends of the first conveying assembly 11 are respectively connected with one second conveying assembly 21, and one of the two second conveying assemblies 21 is an incoming assembly and the other is an outgoing assembly. Further, all the second conveying assemblies 21 are located on one side of the first conveying assembly 11 along the second horizontal direction D2. For example Figure 1 In the figure, along the second horizontal direction D2, the two second conveying assemblies 21 are located on the same side of the first conveying assembly 11, so that the other side of the first conveying assembly 11 along the second horizontal direction D2 forms a safety area la for the work personnel to support the upper and lower support plates 13. Preferably, the second horizontal direction D2 is perpendicular to the first horizontal direction D1.

[0068] Please continue to refer to Figure 1 and Figure 2 The first conveying assembly 11 comprises a plurality of first bearing members 12. Alternatively, the first conveying assembly 11 comprises at least two first bearing members 12.

In the actual operation of the conveying device 1, the at least two first bearing members 12 are used to jointly bear the container. Those skilled in the art know that the size of the container is various, and different numbers of first bearing members 12 may be needed to jointly bear the container. For example Figure 1 In the figure, for the first conveying assembly 11, two first bearing members 12 jointly bear the container 110, and three first bearing members 12 are needed to jointly bear the container 120. The container 110 is configured as a 20-foot container, and the container 120 is configured as a 40-foot container.

[0069] Further, the second conveying assembly 21 comprises a second bearing member 22, and the second bearing member 22 is arranged along the second horizontal direction D2. Along the first horizontal direction D1, the number of second bearing members 22 is at least two and spaced from each other. It should be noted that the bottom of the container 110 has a box wheel, and the second bearing member 22 is adapted to the box wheel, so that the box wheel can move along the second bearing member 22, thereby driving the container 110 to move along the second horizontal direction D2.

[0070] It is appreciated that the support plate 13 is connected to the first carrying member 12 adjacent along the second horizontal direction D2, for example, is connected to the top surface of the first carrying member 12, so that the support plate 13 moves synchronously with the first carrying member 12 along the first horizontal direction D1. In order to facilitate the moving in and out of the container 110 (or the container 120) relative to the first conveying assembly 11, the number of the second carrying members 22 along the second horizontal direction D2 is at least two, and the second carrying members 22 are arranged alternately with the first carrying members 12. Since the bottom of the container has a container wheel, for example, the second carrying member 22 is configured as a carrying track suitable for the container wheel, in order to facilitate the movement of the container between the first conveying assembly 11 and the second conveying assembly 21, the carrying track is arranged in multiple sections, that is, along the second horizontal direction D2, the carrying track is arranged alternately with the first carrying member 12. Preferably, the top surface of the second carrying member 22 is configured to be flush with the top surface of the first station 11b, so that the movement of the container does not bump.

Specifically, the transmission assembly 32 comprises a gear component 38 and a first transmission belt 35. The gear component 38 is pivotably connected to the first conveying assembly 11 around the second horizontal direction D2, and the first transmission belt 35 is engaged with the gear component 38. The driving member 31 is connected with the gear component 38 and is used to drive the gear component 38 to rotate. Further, the gear component 38 comprises a driving wheel 36, and the transmission assembly 32 further comprises a second transmission belt 33. The driving wheel 36 is connected with the driving member 31 through the second transmission belt 33, so that the driving member 31 drives the driving wheel 36 to rotate. The transmission assembly 32 further comprises a synchronous wheel 34, which is coaxially connected with the driving wheel 36, and the radius of the synchronous wheel 34 is smaller than that of the driving wheel 36. The synchronous wheel 34 is connected with the driving member 31 through the second transmission belt 33. It is to be noted that the driving member 31 can be configured as a motor, further, can be a speed reducer motor, and the driving member 31 has an output wheel 31a for connecting with the second transmission belt 33.

[0072] Please continue to refer to Figure 3 The gear component 38 further comprises a driven wheel 37, which is arranged at a distance from the driving wheel 36 along the first horizontal direction D1. The driven wheel 37 is pivotably connected to the first conveying assembly 11 around the second horizontal direction D2, and the driven wheel 37 is connected with the driving wheel 36 through the first transmission belt 35 to follow the driving wheel 36 to operate. Preferably, the number of the driving wheel 36 and the driven wheel 37 is at least two, and they are arranged at a distance from each other along the first horizontal direction D1.

The number of driven wheels 37 is two, and adjacent driven wheels 37 are spaced along the first horizontal direction D1. It is to be noted that when the first conveying assembly 11 is configured as a multiple-speed chain conveying line, the first transmission belt 35 can serve as the first carrying member 12. Alternatively, to avoid the first transmission belt 35 causing scratches on the surface of the container, the first carrying member 12 is additionally provided and connected to the first transmission belt 35, the first carrying member 12 moves synchronously with the first transmission belt 35, and the first carrying member 12 is configured to carry the container.

[0073] It is to be understood that, in order to coordinate the orderly operation of the conveying device 1, the conveying device 1 can further comprise an electric control assembly electrically connected to at least the first conveying assembly 11 to at least control the orderly start and stop of the first conveying assembly 11. The conveying device 1 further comprises a display component electrically connected to the electric control assembly to display the operation status of the conveying device 1 in real time.

[0074] It is to be noted that, Figure 3 In some embodiments, the driving member 31 is used in cooperation with the gear component 38 to drive the first carrying member 12 to operate. However, the present application is not limited thereto, and any one of chain transmission, belt transmission, gear transmission, or a combination of several modes can be used, as long as the orderly operation of the first carrying member 12 can be achieved.

[0075] Hereinafter, a conveying method suitable for the conveying device 1 described above is described.

[0076] Please refer to Figure 1 The number of second conveying assemblies 21 is two, and each of the second conveying assemblies 21 is connected to the two ends of the first conveying assembly 11 in the first horizontal direction D1.
