Detailed implementation manners

[0023] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the attached drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0025] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right", etc. can be used here to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art belonging to the technical field of the present invention. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] The present invention will be described in detail below with reference to the accompanying drawings: A logistics sorting line of the present invention includes a conveyor 1, a swing wheel mechanism, and a camera. The sorting line includes a plurality of conveyors 1. A swing wheel mechanism is provided between two adjacent conveyors 1. An installation frame 3 is provided on the conveyor 1 at the loading end. The camera is disposed on the installation frame 3. A light source 5 is also provided on the installation frame 3. The camera can take pictures of the barcodes on the express packages with the assistance of the light source 5 and send them to the control system for identification.

[0028] The swing wheel mechanism is installed on a frame 9, and the frame 9 is installed on a turntable 10. Both the frame 9 and the turntable 10 are installed in a housing 2. The swing wheel mechanism includes a housing 11, a roller 12, and a transmission mechanism. On both sides inside the housing 11, a first sliding block 15 and a second sliding block 17 are respectively arranged through a slide rail assembly. A first gear 13 and a large gear 14 that mesh with each other are arranged on the first sliding block 15. A second gear 16 is arranged on the second sliding block 17. Both ends of the roller 12 are respectively connected to the first gear 13 and the second gear 16. An intermediate gear 18 and a small gear 19 that mesh with each other are arranged at the position of the second gear 16 inside the housing 11. A rotating shaft 20 is connected to the large gear 14 and the small gear 19. A driven bevel gear 21 is installed on the rotating shaft 20. An input shaft 23 is arranged at the bottom of the housing 11. A driving bevel gear 22 that meshes with the driven bevel gear 21 is arranged on the input shaft 23.

[0029] A chute 27 is arranged inside the housing 2. A support block 28 is elastically arranged in the chute 27, that is, a spring 29 is arranged in the chute 27, and the spring 29 can elastically support the support block 28. Openings are arranged at both ends of the chute 27. A fixed seat is installed at the opening. A rotating seat is hinged on the fixed seat. A torsion spring 32 is arranged between the rotating seat and the fixed seat. The rotating seat supports the bottom of the support block 28 under normal working conditions. The support block 28 is connected to the first sliding block 15.

[0030] A driving shaft 25 is arranged inside the frame 9. A driving motor 26 is connected to the end of the driving shaft 25. Transmission bevel gears 24 that mesh with each other are respectively arranged on the input shaft 23 and the driving shaft 25.

[0031] A first infrared pair is arranged at the unloading end of the conveyor 1. Second infrared pairs 7 are arranged on both sides of the swing wheel mechanism. A third infrared pair 8 is arranged at the loading end of the conveyor 1. The first infrared pair is used to detect whether the express has entered the swing wheel mechanism. The second infrared pairs 7 and the third infrared pair 8 are used to detect whether the express that has entered the swing wheel mechanism has been sorted. If not sorted, that is, the first infrared pair detects a signal, and neither the second infrared pairs 7 nor the third infrared pair 8 detects a signal, then the control system controls the conveyor 1 before this swing wheel mechanism to stop working until the first infrared pair or the second infrared pairs 7 detect a signal.

[0032] During the sorting process of the balance wheel mechanism, when the weight of the express item reaches a certain value, the rotating plate 31 and the spring 29 will no longer be able to support the support block 28, causing the roller 12, the first sliding block 15 and the second sliding block 17 to move downward. The downward movement of the first sliding block 15 can drive the driven bevel gear 21 connected to the large gear 14 to move downward, disengaging it from the meshing with the driving bevel gear 22. At the same time, as the second sliding block 17 moves downward, the second gear 16 meshes with the intermediate gear 18 to continue providing power. At this time, the torque transformation is completed, increasing the torque to prevent the roller 12 from stopping working due to insufficient torque. When the express item leaves the balance wheel mechanism, the spring 29 can lift the support block 28, and the rotating plate 31 rebounds to continue supporting the support block 28.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
