PREFERRED EMBODIMENT OF THE INVENTION

[0048] A Detailed Explanation of an Example of Preferred Embodiment of the Object of the Present Invention is Provided Below, with the Aid of the Aforementioned Figures.

[0049] FIG. 1 Illustrates a Frontal View of a Preferred Embodiment of the Invention Wherein it is Shown that the Installation (1) Comprises a Frame (3) Comprising in Turn Two Portions (4,5) as Shown in FIG. 2 and Wherein Each Portion (4,5) Comprises Round Ends (20).

[0050] FIG. 1 also illustrates four trolleys (7) operatively attached therebetween the front portion (4) and the rear portion (5) of the frame (3), wherein each trolley (7) comprises holding means adapted to grip the crates (2) and further able to hold the crate (2) walls firmly,

[0051] FIG. 2 illustrates an upper view of the preferred embodiment of the invention wherein it is shown that the frontal portion (4) and rear portion (5) of the frame (3) comprises perimetral guides (6) provided with a predefined path whereby the trolleys (7) travel.

[0052] The trolleys (7) are operatively fixed to the frame (3) and comprises a projection adapted to fixe on the perimetral guides (6) so that the trolley (7) follow the defined path.

[0053] Furthermore, FIG. 2 illustrates a conveyor belt (8) operatively coupled to the trolley (7) and to the perimetral guides (6) so that the conveyor belt (8) is adapted to round-trip along each of the frame portions (4,5).

[0054] As shown in FIG. 1 the conveyor belt (8) is moved by at least one power system (9) housed on one of the round ends (20), said power system (9) further comprising a control system configured to control acceleration and deceleration of said conveyor belt (8) and to set a synchronization speed.
