There is a flipping mechanism between two adjacent conveyor belts, and the box 6 is in an "L" shape. The font trajectory moves, and after flipping through the two flipping mechanisms, full disinfection of the six sides of the box can be achieved.

The first mode control method of the fully automatic disinfection system used in box transportation of the present invention includes the following steps:

Step 11. The box 6 moves on the first conveyor belt 81. When passing through the sterilization channel 9, its top surface d, left surface e and right surface f are disinfected and sterilized by the sterilization device on the inner wall of the sterilization channel 9; the sterilization device is an ultraviolet sterilization device or disinfection device. agent spraying device;

Step 12. The box 6 enters the two-way flip plate 3 of the two-way flip machine. The first pressure sensor on the two-way flip plate 3 senses and sends a signal to the controller. The controller makes the two-way flip plate 3 flip according to the agreed flip direction and Fall onto the second conveyor belt;

Step 13. The box 6 moves on the second conveyor belt 82. When passing through the sterilization channel 9, its front a, back b and right side f are disinfected and sterilized by the sterilization device on the inner wall of the sterilization channel 9;

Step 14. The box 6 enters the two-way flipping plate 3 of another two-way flipping machine. The first pressure sensor on the two-way flipping plate 3 senses and sends a signal to the controller. The controller makes the two-way flipping plate 3 move according to the agreed flipping direction. Flip and fall onto the third conveyor belt 83;

Step 15: The box 6 moves on the third conveyor belt 83. When passing through the sterilization channel 9, its front a, back b and bottom surface c are disinfected and sterilized by the sterilization device on the inner wall of the sterilization channel 9, completing the six-sided sterilization of the box 6;

The second mode control method of the fully automatic disinfection system used in box transportation of the present invention includes the following steps:

Step 21. The box 6 moves on the first conveyor belt 81. When passing through the sterilization channel 9, its top surface d, left surface e and right surface f are disinfected and sterilized by the sterilization device on the inner wall of the sterilization channel 9;

Step 22. The box 6 enters the two-way flip plate 3 of the two-way flip machine. The first pressure sensor on the two-way flip plate 3 senses and sends a signal to the controller. The controller makes the two-way flip plate 3 flip according to the agreed flip direction and Drop to the second conveyor belt; another box 6 enters the two-way flipping plate 3 of the two-way flipping machine.

The advantage of the second mode is that the bidirectional flipping structure realizes the diversion of the box, so the box can be disinfected and classified at the same time, improving the efficiency of disinfection and separation of logistics.

In addition, it needs to be added that even if there is a problem in the flipped state, such as flipping it one more time, the antivirus effect will not be affected. For example: As shown in Figure 7, when the disinfection surface is turned over from efd-abf-abc, if the box flips one more surface when it passes through the two-way flipping mechanism for the first time, then the disinfection surface will directly become efd-abc, which is also possible.

The parcel boxes which do not exceed the weight The body 4 is transferred from the low conveyor belt 2 to the high conveyor belt 3 through the flipping and lifting mechanism 5. At the same time, the bottom surface 41 of the parcel box 4 changes from a hidden surface to an exposed surface that can be irradiated by the ultraviolet emitter 14. The parcel box 4 whose weight does not exceed the standard passes through the high conveyor belt 3. Exit 12 output.

The above is only a better solution, and the high-level conveyor belt 2 can also input the package boxes 4 to be sterilized from the high-level entrance 12, and the package boxes 4 with excessive weight are directly output from the high-level exit through the high-level conveyor belt 2. The package box 4 whose weight does not exceed the standard is transferred from the high conveyor belt 3 to the low conveyor belt 2 through the flipping and lifting mechanism 5, and at the same time, the bottom surface 41 of the package box 4 changes from a hidden surface to an exposed surface that can be irradiated by the ultraviolet emitter 14. The parcel box 4 is output through the high-level outlet 12 .

The two technical solutions of transferring from high-level conveyor belt to low-level conveyor belt and transferring from low-level conveyor belt to high-level conveyor belt are equivalent.
