Module for turning over folding packages and folding package production line incorporating such a module

A module for turning over folding packages that can be incorporated in a folding package production line, comprising:

• a frame having first and second vertical pillars;
• and
• a rotary turnover structure arranged horizontally between the vertical pillars, the rotary turnover structure comprising:
• first and second rotation shafts supported by first and second bearings with which the first and second vertical pillars are respectively equipped;
• a first motor for applying a first mechanical torque to the first rotation shaft;
• additional means for applying a second mechanical torque to the second rotation shaft;
• at least one double-belt conveyor arranged vertically and comprising a horizontal pinching plane in an intermediate zone, the at least one double-belt conveyor being configured to transport and hold the folding packages between high and low belts of the at least one double-belt conveyor;
• and
• a mechanism for driving the high and low belts,
• wherein the mechanism for driving the high and low belts is actuated by a motive driving pulley, actuated in rotation by a second motor,
• the mechanism includes pulleys and transmission rods,
• the motive driving pulley transmits the rotation to the pulleys,
• the pulleys transmit the rotation to the transmission rods,
• the transmission rods extend horizontally along the rotary turnover structure in a direction from the first vertical pillar to the second vertical pillar, and
• the transmission rods transmit the rotation to belt driving drums of the at least one double-belt conveyor for each of the high and low belts.
