Abstract

The module ( 3 ) comprises a frame having vertical pillars ( 30 A, 30 B), a rotary turnover structure ( 4 ) arranged horizontally between the vertical pillars and comprising rotation shafts ( 400 A) supported by bearings ( 300 A) with which the vertical pillars are respectively equipped. A motor ( 303 B) applies a first mechanical torque to one of the rotation shafts when a folding package turnover is ordered in the machine. The module also comprises additional means ( 5 ) for applying a second mechanical torque to the other rotation shaft upon a folding package turnover.

First claim

The invention claimed is:

1. 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.

2. The module of claim 1 , wherein the additional means comprise a transmission shaft coupled mechanically in rotation to the first motor and applying the second mechanical torque to the second rotation shaft, a sum of the first mechanical torque and the second mechanical torque corresponding to a total mechanical torque supplied by the first motor.

3. The module of claim 2 , wherein the additional means further comprises a first pulley and a first distribution belt for mechanically coupling in rotation the transmission shaft to the first motor.

4. The module of claim 2 , wherein the additional means further comprises a second pulley and a second distribution belt for mechanically coupling in rotation the transmission shaft to the second rotation shaft.

5. The module of claim 1 , wherein the first motor and the additional means simultaneously apply the first mechanical torque and the second mechanical torque to the first rotation shaft and the second rotation shaft.

6. The module of claim 1 , wherein the at least one double-belt conveyor is one of two double-belt conveyors, the two double-belt conveyors being arranged vertically, and the rotary turnover structure further comprises means for adjusting a distance between two respective vertical planes of the two double-belt conveyors.

7. The module of claim 1 , wherein the at least one double-belt conveyor comprises first and second sets of rollers mounted on dedicated jacks arranged vertically and distributed over a length of transport of the at least one double-belt conveyor, the first set of rollers guiding a low belt of the high and low belts of the at least one double-belt conveyor and the second set of rollers guiding a high belt of the high and low belts of the at least one double-belt conveyor.

8. The module of claim 7 , wherein adjustable and different pressures are applied to the high and low belts by the dedicated vertical jacks at a level of the horizontal pinching plane of the at least one double-belt conveyor, a pressure applied to the low belt supporting a weight of the folding packages being greater than a pressure applied to the high belt.

9. A folding package production line comprising a folding-gluing machine, a counting-segmentation module, a turnover module, and a set of conveyors, wherein the turnover module is a module as claimed in claim 1 for turning over folding packages.
