- the assembly 100 comprises the packaging 1 free of its damping covers which have been removed, as well as a removable handling structure 30 specific to the present invention.
- the handling structure 30 is designed to be coupled in a removable manner on the first axial end 8a, in order to allow the conventional handling operations of this packaging, such as its tilting from the horizontal position to the vertical position, and vice versa.
- this handling structure 30 is very preferably implemented when the packaging 1 has no permanent handling devices on its side body 8.
- the removable handling structure 30 firstly comprises a support device 32, comprising a crown 34 extending over 360° while being centered on the axis 2.
- the support device 32 can also comprise lugs 36 having axially from the crown 34, as well as reinforcing beams 38 connecting the lugs 36 together.

- the removable handling structure 30 also comprises several gripping devices 42, carried by the support device 32. More preferentially, the gripping devices 42 are distributed and spaced apart circumferentially along the crown 34 on which they are fixed, for example at using screws/bolts, being attached to the outer periphery of this crown 34. These gripping devices 42 can be provided eight in number, as in FIG. 2. Nevertheless, this number can be different, for example four .
- Each gripping device 42 adopts the general shape of a lying U when the axis 2, on which the handling structure 30 is centered, is arranged vertically.
- One of the branches 44 of the U serves as an axial support for the gripping device 42 on the crown 34.
- the other branch 46 of the U forms an axial coupling member at the first end 8a of the lateral packaging body 8 , as will be detailed below.
- the base 48 of the U oriented vertically in FIG. 2, forms a radial abutment member which, in the coupled configuration shown in FIG. 3, is in contact or facing radially from a periphery of the first axial end 8a.
- the first axial end 8a of the lateral packaging body 8 comprises a plurality of elements 52 for axial retention of the handling structure 30. Their number corresponds to that of the gripping devices, since they are intended to cooperate in pairs. of them.
- Each axial retaining element 52 takes the form of a block of material extending radially outwards at the periphery of the first axial end 8a, that is to say projecting outwards along the radial direction of assembly 100, relative to axis 2.
- Each axial retainer 52 is defined by an adjacent recess 54, L-shaped lying when the assembly 100 is oriented vertically. More specifically, each recess 54 includes a radial opening 56, open radially outwards, which is continued by a circumferential opening 58 also open radially outwards. It is the combination of these two openings 56, 58 which forms the L-shaped recess, suitable for creating a bayonet/claw connection with the axial coupling member 46 of the associated gripping device 42.
- the axial coupling member 46 is axially facing or in contact with an axial abutment surface 60 defined by the axial retaining element 52, this surface 60, preferably orthogonal to the axis 2 , being oriented in the direction of the second axial end 8b of the packaging side body. It is the cooperation between these two elements 52, 60 which provides the axial mechanical coupling between the handling structure 30 and the packaging 1, at its first axial end 8a on the lid side.
- Figures 4 to 6 showing different successive steps operated to mount the handling structure removable 30 on the first axial end 8a of the packaging, arranged in a horizontal position.
- the number of handling pins 40 is reduced to two, while the number of gripping devices 42 is reduced to four, as is the number of recesses 54 as well as the number of axial retaining elements 52 defined through these recesses.
- each axial coupling member 46 located axially opposite and at a distance from the radial opening 56 of its recess. partner 54.
- this structure 30 is moved axially until each axial coupling member 46 is in the bottom of the radial opening 56 of its recess. associated 54.
- the handling structure 30 is then in a configuration of positioning on the packaging, but not coupled.
- each axial coupling member 46 is gradually introduced into the circumferential opening 58 of its associated recess 54, until it finds itself in the bottom of this opening 58, facing axially or in contact with the axial retaining element 52, as seen in Figure 3.
- the radial opening 56 is thus released by the gripping device 42, but one or more of them may be equipped with a locking device (not shown) of the handling structure 30 in the coupled configuration. It can for example be a device mounted in this radial opening 56, and forming a circumferential stop for the axial coupling member 46.
- flanges 62 can be connected to the journals 40, with these flanges 62 themselves connected to a beam suspended from a gantry, so as to lift the structure 30 and cause the packaging to tilt. 1 to the vertical position, as shown in Figure 7. This tilting is then performed in a known manner, by pivoting the assembly 100 about a horizontal axis of rotation, close to or crossing the second axial end 8b of the side body packaging.
- the assembly 100 comprises the packaging 1 free of its damping covers which have been removed, as well as a removable handling structure 30 which is here segmented into several angular structural sectors 30'. More specifically, these are two sectors 30' of approximately 180° each, intended to be mounted end to end in the coupled configuration, so as to form together a complete annular structure. The number of sectors 30' could nevertheless be greater, without departing from the scope of the invention.
- Each angular structural sector 30' first of all comprises a part 32' of the support device 32, comprising in particular an angular crown sector 34'. End to end, the two angular crown sectors 34' form the crown 34 extending over 360°, and centered on the axis 2. This characteristic is preferably retained in all the embodiments integrating angular crown sectors, whatever regardless of the number of sectors.
- Part 32' of support device 32 also includes one or more lugs 36, each extending axially from crown sector 34'.
- Each angular structural sector 30' also includes one or more separate handling devices, here the pins 40 integral with the lugs 36, and provided two in number per sector.
- Each pin 40 is here also conventionally oriented with its central longitudinal axis oriented radially.
- the number of journals 40 could be different, for example two in total, diametrically opposed.
- the journals 40 are intended to cooperate with flanges 62, themselves connected to a lifting beam 64 suspended from a gantry.
- each part 32' of the support device 32 and more precisely, each angular sector of crown 34', extends around the first axial end 8a.
- Each angular structural sector 30' also comprises a gripping device carried by the part 32' of the support device 32.
- This gripping device here takes the form of a tongue 46 extending radially inwards from the angular sector crown 34 ', to form the axial coupling member.
- This tab 46 preferably extends all along its associated crown angular sector 34', so as to form a single axial coupling member within each angular structure sector 30'. This characteristic is moreover preferably retained for all the embodiments involving crown angular sectors.
- Each structural angular sector 30' also includes another tongue 66, extending radially inward from the crown angular sector 34', parallel to the tongue 46.
- the tongue 66 also extends all along its sector. associated angular crown 34', and it corresponds to that of the two tabs 46, 66 axially farthest from the second end of the lateral packaging body 8. Due to the association of the angular crown sector 34' and the two tabs 46, 66, each gripping device adopts, in cross section taken outside the lugs 36, the general shape of a lying U when the axis 2 is arranged vertically, with the hollow of the U oriented radially inwards.
- first end 8a On the first axial end 8a, there is provided a single axial retaining element 52, formed by an annular collar extending radially outwards in relation to the axis 2. Under this collar 52, it is defined in the first end 8 has an annular groove 70 in which the axial coupling tab 46 is intended to be housed in the coupled configuration of each structural sector 30'.
- This solution further strengthens the mechanical strength of the handling structure on the packaging.
- the tab 66 of each structural sector 30' forms one of the branches of the U which serves as an axial support for this sector 30' on the collar 52 of the first axial end 8a.
- the tongue 46 forms the other branch of the U, and constitutes the axial coupling member housed in the groove 70, being arranged in contact with or facing axially the axial abutment surface 60 defined by the collar 52 , in coupled configuration.
- the base of the U formed by the angular crown sector 34' oriented vertically in FIGS. 8 to 10, constitutes a radial abutment member which, in the coupled configuration, is in contact with or facing radially a periphery of the flange 52, as can be seen in FIG. 10.
- the cooperation obtained between these elements 34', 52 allows radial coupling between the lateral packaging body 8 and the angular sector of the structure 30', particularly useful during a package tipping operation 1.
- the axial coupling tab 46 is axially facing or in contact with the axial abutment surface 60 defined by the axial retaining flange 52, this surface 60, preferably orthogonal to the axis 2, being oriented in the direction of the second axial end of the lateral packaging body 8. It is the cooperation between these two elements 52, 60 which confers the axial mechanical coupling between each angular sector of the handling structure 30' and the packaging 1, at its first axial end 8a on the lid side.
- each angular structural sector 30′ is first placed in position with respect to the packaging 1, so that it is radially separated from the latter, with the hollow of its U oriented radially opposite of the collar 52, as shown in FIG. 8. From this uncoupled configuration, each angular sector of structure 30' is moved individually and relative to the first axial end 8a by translation of this sector, still in the fictitious plane of relative displacement P arranged orthogonally to the axis 2. The directions of translation of the two sectors 30' are shown diagrammatically by the arrows 74 in FIG. 8. This plane P therefore crosses each angular sector of crown 34' and collar 52 throughout the displacement of the structural sectors 30'. During these movements, each axial coupling tongue 46 is gradually introduced into the groove 70, until it finds itself in the bottom of this groove, arranged axially opposite or in contact with the axial retaining tongue 52, as can be seen in Figure 10.
- the two sectors 30' are then assembled end to end by bolts 76, shown in FIG. 9.
- the coupling produced then makes it possible to carry out the required handling operations, as indicated for the first preferred embodiment described above.
- FIGS 11 and 12 show an alternative to the second embodiment which has just been described.
- the elements bearing the same numerical references therefore correspond to identical or similar elements.
- each axial coupling tongue 46 is gradually introduced into the groove 70 of the first end 8a, until it is found in the bottom of this groove, arranged axially opposite or in contact with the axial retaining tongue 52.
- the two sectors 30' are then assembled end to end by bolts, at the level of the two free ends.
- the two connected ends of the two angular structural sectors 30' can be connected other than by a hinge, the connection retained must nevertheless allow the opening and closing described above to ensure the assembly of the structure 30 around the packaging 1.
- FIGS 13 and 14 show yet another alternative to the second embodiment.
- the elements bearing the same reference numerals therefore correspond here also to identical or similar elements.
- each sector 30' can extend over 10 to 45°.
- a moving structure 80 is provided, ensuring the opening and closing of the removable handling structure. 30 thus composed of its two sectors of reduced angular amplitude.
- the structure 80 for setting the sectors 30' in motion can take any form, for example that of two actuating arms 84 arranged in an X and hinged at their center. With such a design, two ends of the X are respectively connected to the two sectors 30', being preferably articulated on the two handling pins 40. Furthermore, the other two ends of the X are for example connected to the lifter 64, being connected to each other by a jack 82 capable of adjusting their spacing, and therefore the radial spacing between the two structural sectors 30' intended to come into engagement with the collar 52.
- FIG. 15 shows a third preferred embodiment of the invention, in which the U-shaped gripping devices 42 are each intended to cooperate with the same flange 52 of the first axial end 8a of the lateral packaging body 8.
