Pallet conveying module

A pallet conveying module, comprising a support structure where there is arranged a travel track configured for a displacement of pallets provided with a loading surface and support legs, the travel track comprising displacement means configured to displace the pallet and a retaining system configured to stop the pallet on the travel track at a predetermined point, wherein the retaining system comprises:

• a first non-motorized mechanically operated braking device having a retractable region allowed for rotating with respect to a shaft with a stop projection, the stop projection being provided to abut with the support legs of the pallet to be stopped, a displacement of a retractable element being by contact with at least one leg of the pallet, wherein in a standby position, the retractable region is on an inclined plane with respect to a horizontal plane, while in a stop position the retractable element is on the horizontal plane, the stop projection abutting against a leg of the pallet;
• and
• wherein
• a second motor operated braking device, wherein the second motor operated braking device is located prior to the first non-motorized mechanically operated braking device, wherein the second motor operated braking device has a cam system, the cam system is defined by first and second retractable stops, and the first and second retractable stops are located in different longitudinal positions with respect to an axis of displacement or advancement of the pallets to be handled, the first and second retractable stops being configured in such a way that, depending on dimensions of the pallet to be stopped, the first or second retractable stop acts.
