The present invention describes a demijohn palletizer 1, which is characterized in that it comprises two engine bases 2, 2'; two engines 3, 3' that are respectively attached on the engine bases 2, 2'; a conveyor belt 4 that is conveyed by means of the engine 3 and which carries demijohns G that are previously filled in with water and inspected for ensuring the purity thereof; the same controls the demijohns G accumulation in order to avoid a friction therebetween, thereby facilitating the demijohns to be slightly fed to a first step of the palletizer by means of control switches that are located under the conveyor belt 4, where a water draining rack is placed 5.When a photocell F counts four demijohns G the same sends a signal that activates a piston P, which blocks the conveyor belt 4 travel and ensures the said four demijohns G are fed in said first step. Moreover, a mechanism guide that is driven by a pneumatic cylinder 6 descends down to the conveyor belt level 4, and a pusher 7 t hat is attached to a mobile fastener 9 softly places the demijohns G on a turning device 8, then the pneumatic mechanism 6 returns to its home position. The turning device 8 spins about 90 degree in order to take the demijohns G from the vertical position to a horizontal position, thereby positioning the same at a tilted plane; said turning device includes an activated brake, once the demijohns G are placed in the correct position, the same is contracted and allows the demijohns to roll towards a spacing and thrusting table 10, the tilted plane being useful for detecting the demijohns by a sensor in order to place the same in a correct manner; then the demijohns spacing pistons 11 are driven for providing the correct distance at which the demijohns G will be fed by the table 10 to a lift or mobile platform 12 that is moved by the engine 3'. The aforesaid is carried out twice in order to form a stack 14 of eight demijohns G that has a lifting stack aligning tool 15, stack chain fasteners 16 and lifting stack bearings 17. Once said stack is completed the same starts rising up to the maximum level of a grid that is placed on a grid base 13. Once the lift that has been fed with the demijohns G is placed, a pushing mechanism is driven in order to fill in part of the grid with the demijohns G from an upward to a downward direction and vice versa until the total filling of the grid is completed, the same being removed by a forklift vehicle.
