    INERTABLE CONTAINER FOR TRANSPORTING ADDITIVE MANUFACTURING POWDER The invention relates to the field of powder-based additive manufacturing by melting the grains of this powder using one or more power sources such as one or more laser beams and / or one or more electron beams.
    More specifically, the invention is in the field of additive manufacturing by depositing a powder bed or by spraying powder.
    The invention aims to facilitate the transport and storage of several tens of liters of additive manufacturing powder while preserving the qualities of the powder. The invention also aims to facilitate the supply of powder to various additive manufacturing machines or to other devices useful for additive manufacturing such as sieving or powder drying devices. The invention also aims to facilitate the recovery of powder from various additive manufacturing machines or from other devices useful for additive manufacturing such as sieving or powder drying devices, or devices for cleaning the workpieces and trays Manufacturing. Finally, the invention also aims to facilitate the packaging or reconditioning of batches of new or recycled powder.
    In the field of additive manufacturing by depositing a powder bed or spraying powder, the quality of the parts produced is directly linked to the quality of the additive manufacturing powder used. Therefore, if the quality of the powder is degraded during its transport, its storage, or its transfer to an additive manufacturing machine or to another device, the parts manufactured with this powder will offer poorer performance or may even have faults leading to the disposal of these parts.
    For example, the chemical composition of an additive manufacturing powder can change by physicochemical reaction, such as for example by oxidation, by adsorption or by absorption, in contact with water vapor, oxygen and / or nitrogen contained in the air present in the workshop where the powder is used, and this development can cause a reduction in the mechanical resistance of the parts produced or a reduction in the corrosion resistance of the parts produced.
    At the same time, and due to certain toxic chemical compounds that they may contain or the risk of fire or explosion linked to their reactivity with oxygen, certain additive manufacturing powders can also present health risks, d 'hygiene or safety vis-à-vis the people present in the workshops where these powders are handled and used.
    So, both to preserve their quality and the health and safety of people, it is generally necessary to transport, store and transfer the additive manufacturing powders in sealed containers or in closed circuits, and avoiding put these powders in contact with the air present in the premises where these powders are used.
    Currently, additive manufacturing powders are supplied in sealed jars and containing only a few liters of powder in an inert gas. On the one hand, several pots are necessary to supply an additive manufacturing machine for an entire production cycle. In addition, these pots do not allow sufficiently airtight storage to the outside air and to the water vapor contained in this outside air over time. And finally, once opened, these jars cannot be reused to re-store the powder in an inert atmosphere.
    There is therefore a need to be able to transport several tens of liters of additive manufacturing powder with a single container, reusable and capable of containing the powder in a protected atmosphere and in a hermetic manner to the outside air and to the steam of water contained in this outside air over time.
    Finally, the additive manufacturing powders are fluid and elusive products, and there is a need to facilitate the handling of these powders while preserving the quality of the powders and the health and safety of people, for example by limiting the risk of fire and explosion during transport or transfer of reactive oxygen powders.
    The present invention aims to provide a solution to the above needs.
    To this end, the invention relates to an inert container for transporting a powder of additive manufacturing, the container comprising an inert volume and a main opening giving access to the interior of this inert volume, the inert volume comprising an upper part and a lower part, the main opening being situated in the lower part of the inertable volume, and the section of the inertable volume progressively increasing in at least part of the height of this inertable volume and from the lower part towards the part greater than the inertable volume.
    According to the invention, the main opening is equipped with a passive half-valve making it possible to close this main opening in an airtight and air humidity-tight manner, and the container comprises at least two inerting nozzles, at least a first upper nozzle giving access to the upper part of the inertable volume and at least one second lower nozzle giving access to the lower part of the inertable volume.
    Thanks to the passive half-valve, the container makes it possible to contain the powder in a protected atmosphere and in a hermetic manner to the outside air and to the water vapor contained in this outside air over time, and thanks to the tappings. the container can be refilled with an inert gas for a new use with a new batch of powder.
    In addition, when the inerting nozzles are connected to an inert gas supply circuit, these nozzles can be used to maintain the pressure and the rate of inert gas in the container at constant values, thus making it possible to compensate for any micro-leaks and guarantee the quality of the powder contained in this container over time.
    Other characteristics and advantages of the invention will appear in the description which follows. This description, given by way of example and not limiting, refers to the attached drawings in which:
    Figure 1 is a perspective view of a container according to the invention in a first embodiment, Figure 2 is a sectional view along a transverse median plane of a container according to the invention in a first embodiment , Figure 3 is a perspective view of a container according to the invention in a second embodiment, and Figures 4A and 4B are side views of a container according to the invention in a second embodiment.
    The invention relates to an inert container 10 for transporting an additive manufacturing powder as shown in FIGS. 1 to 4B.
    By additive manufacturing powder, the invention means a powder whose grains have their largest dimension less than or equal to five hundred micrometers.
    [019] In an application particularly targeted by the present invention, the grains of this powder are liable to be altered by contact with the air present in the premises where this powder is used or by contact with the humidity of this air.
    For example, the powders intended to be transported or stored with an inertable container according to the invention are metallic powders comprising at least one or more metals which can be oxidized in contact with oxygen or nitrogen contained in the air present in the premises where these powders are used.
    [021] In order to transport and store such an additive manufacturing powder, the container 10 comprises an inertable volume 12 and a main opening 14 giving access to the interior of this inertable volume 12. In more detail, the inertable volume 12 comprises an upper part 16 and a lower part 18, and the main opening 14 is located in the lower part 18 of the inertable volume.
    [022] In order to avoid replenishment of an additive manufacturing machine during production, the inertable volume 12 has a capacity of at least five liters and can go up to two thousand liters, the capacity of the inertable volume being adapted to the volume of the zone or zones of manufacture of the additive manufacturing machine taking into account the quantity of powder which can be deposited in excess by the means of layering or of projection of the powder.
    [023] To avoid the creation of powder retention zones in the container 10, the section S12 of the inertable volume 12 gradually increases in at least part of the height H10 of this inertable volume 12 and from the lower part 18 towards the part upper 16 of this inertial volume 12. Therefore, the section S12 of the inertable volume 12 gradually increases above the main opening 14, thus promoting the flow of the powder towards this main opening.
    In a first embodiment illustrated in FIGS. 1 and 2, the section S12 of the inertable volume 12 gradually increases in the lower part 18 of this inertable volume 12 and this section S12 of the inertable volume 12 remains constant in the upper part 16 of this inertial volume 12.
    In a second embodiment illustrated by FIGS. 3 and 4A and 4B, the section S12 of the inertable volume 12 gradually increases throughout the height H10 of this inertable volume 12.
    [026] The inertable volume 12 can take a frustoconical or pyramidal shape in the part where its section S12 gradually increases.
    In the first and the second embodiment of the container illustrated in the figures, the inertable volume 12 takes a pyramidal shape with 4 faces with rounded edges between its different faces in the part where its section S12 gradually increases.
    In order to avoid any contact of the powder with the air present outside the inertable volume 12, the main opening 14 is equipped with a passive half-valve 20 making it possible to close this main opening 14 so air and moisture tight.
    [029] In combination with this passive half-valve 20, and in order to be able to fill the inertable volume 12 with an inert gas, the container 10 comprises at least two inerting tappings, at least a first upper tapping 22 giving access to the upper part 16 of the inertable volume and at least one second lower tap 24 giving access to the lower part 18 of the inertable volume.
    Advantageously, the presence of at least two lower and upper nozzles makes it possible to completely fill the inertable volume of inert gas regardless of the position in which the container is used.
    [031] By inert gas, the invention means a gas which does not cause a physicochemical reaction, such as for example oxidation, absorption or absorption, capable of degrading the characteristics and the quality of the manufacturing powder. additive. For example, for some powders, an inert gas can be nitrogen, argon, helium or a mixture of two or three of these gases.
    [032] Thus, when the container is used to feed powder to an additive manufacturing machine or another additive manufacturing device, the container is used with its main opening downwards, and the inert gas is introduced into the inertable volume by a top stitching. However, to facilitate the flow of the powder to the main opening, inert gas can also be introduced into the inertable volume by a lower nozzle. In more detail, by being introduced by a lower nozzle, the inert gas circulates in the powder and makes it possible to break a possible powder vault which would have formed above the main opening. When inert gas is thus introduced by a lower nozzle, the upper nozzle can be used to evacuate inert gas and thus limit the overpressure of inert gas in the inertable volume.
    Conversely, when the container is used to receive powder from an additive manufacturing machine or from another additive manufacturing device, the container is used with its main opening upwards, and the inert gas is introduced into the inertable volume by a lower nozzle.
    [034] Finally, when the container has been opened, emptied and brought into contact with the outside air, the passive half-valve is closed, and two tappings giving access to the inertable volume are used to refill the inertable volume with a inert gas, a first connection being used to introduce the inert gas into the inertable volume and the other connection making it possible to evacuate the non-inert gases present inside the inertable volume and expelled by the inert gas introduced via the first connection.
    As the various figures illustrate, the inertable volume being closed at the top by an upper wall 27, each lower tap 24 is located in the immediate vicinity of the main opening 14, and each upper tap 22 is located near immediate of the upper wall 27.
    For the hermetic closure of the inertable volume, the passive half-valve 20 comprises a body 25 supporting a butterfly 26 for closing the main opening 14 of the container 12 and locking means 28 of this butterfly in the closed position .
    [037] These locking means 28 are unlocked by coupling the passive half-valve with an active half-valve, the locking means allowing the separation of the passive half-valve and the active half-valve only when the butterfly 26 is in the closed position, and the locking means 28 holding the butterfly 26 in the closed position as long as the passive half-valve is not coupled with an active half-valve.
    [038] An active half-valve 30 intended to be coupled with the passive half-valve 20 of the container 10 is illustrated in FIG. 1. This active half-valve 30 comprises a body 32 supporting a butterfly valve 34 intended to be attached to the butterfly valve 26 of the passive half-valve 20. In addition, this active half-valve 30 also includes an actuator 36, for example pneumatic, making it possible to rotate the butterfly 34 of the active half-valve 30.
    [039] Also, the locking means 28 of the throttle valve in the closed position are unlocked by coupling the throttle valve 26 of the passive half-valve with the throttle valve 34 of the active half-valve, the active half-valve comprising means for unlocking of the locking means 28 of the passive half-valve 20.
    For example, the butterfly 34 of the active half-valve forms or supports the unlocking means of the locking means 28 of the passive half-valve 20.
    [041] The locking means 28 of the passive half-valve 20 taking for example the form of at least one key or at least one stud movable in translation, the setting in motion of this key or of this stud when the passive half-valve is coupled with an active half-valve makes it possible to release a rotation of the butterfly 26 and of the butterfly 34 around an axis passing through the main opening 14.
    [042] To actuate the unlocking of the locking means 28 of the passive half-valve 20, the means of unlocking the active half-valve take, for example, the form of at least one pin, or at least one cam, or more simply at least one surface making it possible to set in motion the key or the stud of the locking means 28 of the passive half-valve 20. The pin, the cam or the surface of the unlocking means are for example carried by the throttle valve 34 of the active half-valve.
    [043] When the active half-valve is coupled to the passive half-valve, the means for unlocking the active half-valve unlock the means for locking the passive half-valve, the butterfly 34 of the active half-valve is attached to the butterfly 26 of the passive half-valve, and the rotation of the butterfly 34 under the effect of the actuator 36 of the active half-valve causes the butterfly 26 of the passive half-valve to rotate and therefore the opening of the main opening 14.
    [044] In the second embodiment of the container illustrated in FIGS. 3, 4A and 4B, the inertable volume 12 comprising a right side 38 and a left side 40, the container comprises a lower tap 24 and an upper tap 22 on the side right of the inertable volume, and the container comprises a lower tap 24 and an upper tap 22 on the left side of the inertable volume.
    Still in the second embodiment of the container illustrated in FIGS. 3, 4A and 4B, the container 10 comprising a lower part 42 and an upper part 44, the container comprises at least two lower connectors 46 positioned in the lower part 42 of the container and at least two upper fittings 48 positioned in the upper part 44 of the container. A first upper connector 48 and a first lower connector 46 are connected by the same conduit 50 to a lower nozzle 24 giving access to the lower part 18 of the inertable volume, and a second upper connector 48 and a second lower connector 46 are connected by a the same leads 52 to an upper tap 22 giving access to the upper part 16 of the inertable volume.
    [046] Thus, in the second embodiment of the container, the container comprising lower 24 and upper 22 nozzles on the right 38 and left 40 sides of the inertable volume, the container comprises four connections on each side of the inertable volume. On the right side 38 of the inertial volume, a lower connector 46 and an upper connector 48 are connected by the same conduit 50 to a lower nozzle 24, and a lower connector 46 and an upper connector 48 are connected by the same conduit 52 to a nozzle upper 22. And on the left side 40 of the inertial volume, a lower connector 46 and an upper connector 48 are connected by the same conduit 50 to a lower nozzle 24, and a lower connector 46 and an upper connector 48 are connected by the same conduit 52 to an upper nozzle 22.
    [047] As illustrated by the various figures, the container 10 comprises a chassis 54 inside which is placed the inertable volume 12. This chassis is substantially parallelepipedal and it makes it possible to facilitate the handling of the inertable volume 12 and therefore of the container .
    [048] Advantageously, the lower 46 and upper 48 fittings are supported by the chassis 54 of the container.
    [049] In the container according to the invention, the upper part 16 of the inertable volume is part of the upper part 44 of the container and the lower part 18 of the inertable volume is part of the lower part 42 of the container. Thus, the dimensions of the container 10 are substantially identical to the dimensions of the inertable volume 12.
    Still in order to facilitate the handling of the inertable volume 12, the container 10 comprises rollers 56 in the lower part 42 and in the upper part 44. These rollers 56 are supported by the chassis 54 of the container.
    For the same purpose, the chassis 54 of the container makes it possible to receive a retractable handle 58 in the upper part 44 of the container or in the lower part 42 of the container, depending on the orientation in which the container is used (main opening towards top or main opening down).
    [052] Finally, to allow complete cleaning of the interior of the inertable volume 12, the container 10 comprises an auxiliary opening 60 giving access to the interior of the inertable volume 12, this auxiliary opening being equipped with a closing cover 62 .
    [053] Advantageously, the auxiliary opening 60 is fitted in the upper part 44 of the inertable volume 12. More specifically, the auxiliary opening 60 is fitted through the upper wall 27 of the inertable volume 12.
    [054] This auxiliary opening 60 is large enough to be able to ensure complete cleaning of the interior of the inertable volume 12 and good visual control of the interior of the inertable volume 12, this visual control making it possible to ensure that the interior of the inertable volume 12 is clean and free of any impurity before closing it, filling it with inert gas and introducing a new batch of additive manufacturing powder.
