Method to fully automatically open the side and reclined walls of a plurality of crates preferably for agricultural products, provided with a bottom plane and with two pairs of opposed walls, each of them hinged on said bottom plane, which are arranged in the same and ordered way, and vertically laid one on the other so as to form a respective first stack, wherein it comprises the following operations:
- a) carrying said first stack into an loading station
- b) vertically raising two opposed walls of the upper crate by respective rotation with respect to said bottom plane,
- c) vertically rising of the other two opposed walls of the upper crate by respective rotation with respect to said bottom plane,
- d) blocking of at least one of said side walls to an adjacent side wall,
- e) horizontally transferring said open crate into a position outside the vertical projection of said first stack.
Apparatus for the opening of two pairs of opposed walls of a crate placed on a first stack of closed crates, wherein it comprises:
- lifting means of said first stack to an opening station,
- first opening means of a first pair of opposed walls,
- second opening means of a second pair of opposed walls,
- third reciprocal blocking means between at least two adjacent walls
