DETAILED DESCRIPTION

[0021] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0022] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0023] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0024] Example 1

[0025] As one of the preferred implementations of the utility model conveyor belt right-angle transmission structure, Figure 1 As shown, the corner structure in this embodiment includes: a main conveyor belt 1, an auxiliary conveyor belt 2 and a corner conveyor platform 3. The auxiliary conveyor belt 2 is arranged at one end of the main conveyor belt 1 and is perpendicular to the main conveyor belt 1, and the two form a right-angle corner. The main conveyor belt 1 includes a conveying roller 11 and a conveyor belt 12 arranged on the conveying roller 11. Among them, the conveying rollers 11 located at both ends are active rollers, and the remaining conveying rollers 11 are set as driven rollers. Active rollers can also be arranged at intervals between the driven rollers, and the auxiliary conveyor belt 2 is arranged in the same way. The corner conveyor platform 3 is arranged on the inner side of the corner of the main conveyor belt 1, and its direction is the same as the transmission direction of the auxiliary conveyor belt 2.

[0026] like Figure 2 As shown, a plurality of corner conveyor rollers 31 are arranged on the table of the corner conveyor platform 3, and the movement direction of the corner conveyor rollers 31 is arranged in the same direction as the conveying direction of the auxiliary conveyor belt 2. The corner conveyor platform 3 is driven to lift the table by a lifting cylinder 32 arranged under the table, and a hydraulic telescopic support rod 33 is arranged on both sides of the lifting cylinder 32 to support and maintain the stability of the table. When the goods are transported into the corner by the main conveyor belt 1, the corner conveyor platform 3 is lifted so that the corner conveyor rollers 31 contact the bottom of the goods, and the corner conveyor rollers 31 start to transfer the goods to the auxiliary conveyor belt 2; when the transfer is completed, the corner conveyor rollers 31 are lowered to wait for the next goods to enter the corner.

[0027] Furthermore, a pressure sensor can be arranged on the surface of the corner conveyor platform 3 to detect whether there are objects on the corner conveyor platform 3. When the pressure data detected by the pressure sensor reaches the set pressure threshold, it indicates that the objects transported by the main conveyor belt have arrived. At this time, the corner conveyor roller 31 can be started to transfer the objects to the secondary conveyor belt 2. When the pressure data detected by the pressure sensor is lower than the set pressure threshold, it indicates that the objects have left the corner conveyor platform 3. At this time, the corner conveyor roller 31 can be closed.

[0028] In one embodiment of the present invention, a first photoelectric sensor 13 is provided near a corner of the main conveyor belt 1 to detect whether an object has successfully entered the corner. If the photoelectric sensor detects an object blocking the corner for a long time, it indicates that there is cargo remaining.

[0029] In one embodiment of the present invention, a second photoelectric sensor 21 is provided near the corner of the secondary conveyor belt 2 to detect whether an object has passed the corner smoothly. If the photoelectric sensor detects an object blocking the corner for a long time, it means that there is cargo remaining.

[0030] In another embodiment of the utility model, the structure is further provided with a sound and light alarm device connected to the photoelectric sensor signal, and when the photoelectric sensor detects that an object has been detained for a long time, a sound and light alarm is issued.

[0031] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
