A system having an upstream module M for storing cardboard blanks, a central module C with a device for taking the blanks from the magazine, and a downstream packing and packaging module V having a station where the blanks are erected. The extractor arm is mounted on a carriage which is movable so as to move the blanks lengthwise and the arm is movable relative to the carriage by an actuating mechanism which enables the arm to articulate about an axis. The distance D between the exit edge of the magazine and the reference point of the station is fixed, and the carriage controls the movements of the blank extracted from the magazine in order to avert the risk of interference with the magazine and to position the blank in the station to enable it to be erected, and this for a whole range of forms of blanks.

1. An installation for wrapping and packaging diverse and varied products in a cardboard box, the installation comprises a machine for preparing packages, the machine comprising: an upstream module M configured as a storage site for storing cardboard cutouts blanks, which will form said packages;a downstream module V where each of the cardboard cutout blanks is formed into a box blank, said forming performed in a repository of a forming station wherein a reference point corresponds to a lower upstream edge of the box blank; anda central module C, arranged at least in part between said upstream module and said downstream module, equipped with a device for picking up said cardboard cutouts blanks in said storage site, the pick-up device comprising at least one extractor arm that is borne by a carriage capable of moving, and which moves a cardboard cutout blank from among the cardboard cutout blanks extracted from said storage site for deposit at the forming station,wherein the central module comprises a maneuvering mechanism, at least in part, between said extractor arm and said carriage, that comprises a means for pivoting said extractor arm around a virtual axis located, when said cutout is picked up and moved by said carriage, in a stationary horizontal plane that corresponds to both a plane of a soleplate of said storage site and to that of a plane of a soleplate of said forming station. 2. The wrapping and packaging installation according to claim 1, wherein the maneuvering mechanism comprises: a structure supporting said extractor arm, in a form of a deformable double parallelogram comprising two large sides that form a pair of connecting rods that are pivotably connected to three small sides that are parallel to one another and form segments of a circle,wherein two of the three small sides are each borne by a crankshaft that is pivotably connected to the carriage by shafts that are parallel to the virtual axis of said extractor arm, and a third one of the three small sides acts as a support for said extractor arm and rotates around said virtual axis, andwherein said crankshafts pivot causing said support to move according to a circular movement that enables said extractor arm to move from a position of picking up the cardboard cutout blank in the storage site to a position of depositing said cardboard cutout blank at the forming station, and the reverse. 3. The wrapping and packaging installation according to claim 2, wherein the maneuvering mechanism is arranged on a plate that is borne by the carriage, wherein the carriage is guided on slides or tracks secured to a chassis of the machine and is moved by a drive member of an electric linear motor, andwherein a primary winding is arranged on said carriage and a secondary winding is arranged on said chassis corresponding to said slides or tracks. 4. Wrapping and packaging installation according to claim 1, wherein it comprises an extractor arm that is in the form of a support bar equipped with suction cups, which suction cups are connected to one another, and said support bar is connected, by its ends, to two circuits for activating said suction cups, which circuits are equipped with means enabling them to act together or separately, and said suction cups are equipped, entirely or partially, with three-way valves capable of enabling a maximum number of suction cups to be selected and implemented for the cutout extraction operation, and of isolating one or the other of said circuits so as to enable the deactivation of the suction cup(s) to be bypassed for the forming of said cutout. 5. Wrapping and packaging installation according to claim 4, wherein the support bar (40) with suction cups ahs a length of approximately the dimension of the largest cutout (3) in the case of the “American box”, and slightly lower in the case of the “wrap-around”. 6. Wrapping and packaging installation according to claim 5, wherein the carriage comprises, for “American box”-type cutouts, in addition to the extractor arm, at least one second arm, called the forming arm, which forming arm is maneuvered by means of an actuator in order to go from an inactive position in which it is retracted below the level of the soleplates and to an active position in which it is located between the cutout and the storage site in order to grip the vertical upstream side l″ of said cutout and hold it while said arm pivots the vertical downstream side L′ of the cutout on the soleplate of the forming station. 7. Wrapping and packaging installation according to claim 6, wherein the mechanism for maneuvering the extractor arm comprises members for actuating the latter, which comprises two actuators and arranged side by side: a first actuator that simply brings said extractor arm from its resting position to its active position for picking up the cutout in the storage site anda second actuator that, after movement of the carriage, causes said extractor arm to pivot slightly, and moves the latter, with the cutout, to the vertical position, perpendicular to the bed of the forming station, so as to present the lower upstream side l″ of said cutout to the forming arm, which, once it is in position, enables said extractor arm to pivot, for the assembly of said cutout,in which said first actuator is placed between said second actuator and one of the crankshafts,and said second actuator is pivotably connected to the plate of the maneuvering mechanism, secured to said first actuator. 8. Wrapping and packaging installation according to claim 7, wherein the assembly of the mechanism for maneuvering the extractor arm is arranged on the plate, which is itself pivotably connected to the carriage and in particular to a shaft parallel to the virtual axis of said extractor arm, which plate is capable of being moved by an actuator, for example, to enable said assembly, and in particular said extractor arm, to pivot so as to temporarily retract it below the level of the soleplate of the forming station and with respect to the bottom of the box blank, before said carriage returns to its starting position. 9. The wrapping and packaging installation according to claim 1, wherein the forming station comprises both a station for forming and a station for filling the box blank made from the cardboard cutout blank, and wherein a distance D separates the reference point of said forming station and an edge of an outlet of the soleplate of the storage site. 10. The wrapping and packaging installation according to claim 9, wherein D is less than a length of said extractor arm or D is approximately the length of said extractor arm. 11. The wrapping and packaging installation according to claim 9, wherein D is approximately the length of said extractor arm. 12. The wrapping and packaging installation according to claim 1, wherein, the filling station downstream from the forming station at a distance P from said forming station that enables the extractor arm to return to an active pick-up position upon removal of the box blank that was shaped at said forming station during an operation of filling said box blank. 13. The wrapping and packaging installation according to claim 1, wherein the storage site stores the cardboard cutout blanks on a first-in first-out basis. 14. The wrapping and packaging installation according to claim 1, wherein the virtual axis, when said cutout is picked up and moved by said carriage, is located, within the cardboard thickness range, in the stationary horizontal plane that corresponds to both the plane of said soleplate of said storage site and to the plane of the soleplate of said forming station.
