[0039] Reference Figure 3 The working process of the carton loading and unloading conveying line in this embodiment is introduced in detail, taking unloading as an example:

[0040] When the carton is unloaded from the carriage, the side of the carton is adsorbed by the clamp and is supported at the bottom by the clamp, the transmission mechanism of the second conveying line is lifted to a certain height by the lifting mechanism, and the bottom surface of the carton is contacted; the clamp pushes the carton completely to the transmission mechanism (at this time, the second roller can also be matched to rotate, so that the carton can be quickly transferred to the transmission mechanism); the clamp moves away, the transmission mechanism falls back to the initial height and is flush with the first conveying line, and then the transmission mechanism conveys the carton to the first conveying line, and the first conveying line conveys to the next process.

[0041] At present, when the automatic unloading equipment processes the carton on the top of the carriage, the height difference caused by the supporting mechanism in the clamp is usually not considered, the goods are directly dropped onto the transmission line during unloading, the placing process of the box is unstable, and goods damage and dropping are prone to occur. After the conveying line is adopted, the second conveying line can be lifted or lowered to a preset height, the height difference between the clamp and the first conveying line is made up, and the clamp is cooperated with work to avoid the carton from falling.
