Apparatus for opening in an automatic mode and in a continuous sequence the closed side walls of a plurality of crates, preferably for horticultural products, and preferably lying vertically one on another so as to form a relative first stack, suitable for carrying out the operations for carrying a first stack to a first arrival and loading station, lifting vertically said two pairs of opposite walls, transferring said open crates to a second stack, and subsequently carrying said stack outside the apparatus; the apparatus includes command and control means suitable to store the parameters that correspond to a plurality of types of crates having different dimensions, enter into said command and control means a coded instruction representative of a particular type of crate, and automatically make it so that said command and control means process and transmit to the controls, structures, operating bodies, devices, actuators present in the apparatus appropriate signals that are suitable to determine therein the correct operation corresponding to the type of selected crate. |

1. An apparatus 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, and able of performing the following operations:
a) carrying said first stack into a first 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, wherein after said operation in a), and before said operation in b), said first stack is lifted to a level such as the crate in the upper position and with the reclined side walls, reaches a pre-determined level into said first working station, f) lowering of said crate until a support level of the respective bottom plane on a second working station able of forming a train of opencrates, wherein said blocking d) and transferring e) operations are carried out through the use of a centre operating body able:
of being initially lowered until it is introduced into an opened crate,being acted so as to increase one horizontal size and to contact the side edges of two opposed walls, and to engage by pushing said two edges to corresponding edges of the other two walls,to keep on engaged by pushing said crate and to be horizontally transferred, possibly after a lifting motion, so as to automatically transfer said crate, wherein said centre operating body is able to be lowered for strokes, which can be selectively differentiated, with respect to a common initial level. |
