ABSTRACT:
At least one driving sprocket (H1) and the neighbouring driven sprocket (H2) carrying the two pairs of chains of the compartment conveyor (T) are connected to each other by means of a dog clutch (2, 4) operated by an actuator (15) controlled by the control panel (19) of the packaging machine. The driving shaft (L) on which the said sprockets (H1, H2) are mounted is turned by an electric motor (1) of the electronic speed and phase control type. Adjustment of the length of the compartments (C) of the conveyor is effected automatically by the control panel (19) supplied with the necessary data, which stops the conveyor, opens the said dog clutch (2, 4), starts the said motor (1) so as to move one of the walls (P1) of the compartments by the amount required for the adjustment, and then closes the said dog clutch (2, 4) and, if required, restarts the said motor (1) so as to impart to the conveyor one half of the distance moved in the previous adjustment, forwards or backwards, in order to align the compartments with the product loading station (A).
