Background

At present, in the autoclaved aerated concrete plate production industry, the produced thin plates are mostly required to be turned by 90 degrees for packaging, loading or storing. However, after the existing turnover device is used for turning over the plate, the turnover device is usually required to be reset to an initial state to continue turning over next step, and the conveying line needs to stop working for a period of time during resetting, so that the conveying and packaging efficiency of the plate is reduced, and the requirement of large capacity cannot be met.

For example, the Chinese patent application number is: CN201520030311.2, published as: the patent document of 7/29/2015 discloses a plate turnover mechanism capable of realizing accurate positioning, which comprises a rack and two annular mechanisms, wherein the two annular mechanisms are arranged on the rack and are parallel to each other, a chain is fixedly connected onto each annular mechanism, and the end parts of the chains are connected with a motor for controlling the rotation of the annular mechanisms; the plate fixing device is arranged in the annular mechanism and fixedly connected to the annular mechanism, and comprises two mutually parallel fixed end tables, and each fixed end table consists of a plurality of conveying rollers positioned in the same plane; at least four guide wheels are arranged in the frame and are in contact with the annular mechanism.

According to the technical scheme, the plate turnover mechanism capable of achieving accurate positioning can drive the plate fixing device inside the plate turnover mechanism to overturn together with the plate through the chain-driven annular mechanism, so that the phenomenon that the plate is shifted in position due to the fact that the turnover action force is directly applied to the plate in the plate turnover process is avoided, and the turnover precision is improved. However, when the plate is turned once, especially when the plate is turned for 90 degrees, the next plate can be turned after the plate is reset, so that the whole plate packaging and conveying efficiency is low, and the plate production efficiency is reduced.

Also, for example, the Chinese patent application number is: CN201910735942.7, published as: patent literature of 26 days 11 months in 2019 discloses a panel upset machine, including base and drum-type mount, drum-type mount and base swing joint, be provided with noise reduction box, driving motor and drive gear on the base, be provided with the rack along the circumferencial direction on the outer wall of drum-type mount, rack and drive gear meshing, driving motor installs in noise reduction box and the motor shaft stretch out noise reduction box with drive gear links to each other, noise reduction box includes box and lower box, is provided with the fastening block on the tank wall that last box open end corresponds, is provided with the fastening groove on the tank wall that lower box open end corresponds, fastening block detachable installs in the fastening groove, be provided with cellular cardboard between the inner wall of last box and the outer wall, be provided with on the drum-type mount and hold the chamber.

By arranging the noise reduction box, the working noise can be reduced when the plate is turned over, and the working environment can be purified. However, the problem that the production efficiency of the plate is low because the turnover machine needs to be reset after the plate is turned over, particularly after the plate is turned over by 90 degrees, also exists.

In addition, above-mentioned upset machine is at the during operation, still needs outside clamp to get equipment and gets the board clamp to the upset machine on, the rethread clamp after the upset gets equipment and gets the board from the upset machine goes up the clamp and get to the conveyer line on, has increased the upset time of board to the upset efficiency of board has further been reduced.
