1 / 31 FILLING AND INSTALLATION CAR COMPRISING SUCH FILLING CAR
[0001] The invention relates to a filling car.
[0002] The invention also relates to an installation comprising a filling car such as this. TECHNOLOGICAL FOUNDATIONS OF THE INVENTION
[0003] The general architecture of an electrolyzer stack typically consists of a block of electrolytic cells, which are stacked in series from an electrical point of view and in parallel from a fluidic point of view, and seals.
[0004] The purpose of each electrolytic cell is to promote the electrolysis of an electrolyte solution (alkaline water, pure water, unpurified water, salt, aqueous chloride solution, aqueous bromide solution, aqueous hydrochloric acid solution, etc.).
[0005] For example, the function of an electrolyzer cell is to promote the reaction to produce dihydrogen (H2) and dioxygen (O2) gas resulting from the dissociation of water after injecting a continuous electric current into an alkaline solution, usually potassium hydroxide (KOH) or sodium hydroxide (NaOH).
[0006] Each electrolytic cell, which is considered to be a conductive part, primarily metal (but some portions of which may be non-metal), is generally made up of two bipolar plates flanking two inserts (more commonly known as flux field material), which in turn flank two electrodes, usually in the form of Petition 870260045161, dated 05 / 13 / 2026, page 7 / 50 2 / 31 metal plates or grids or meshes. In the case of an alkaline electrolyzer cell, said electrodes are usually made of nickel. The two electrodes (a cathode and an anode) are separated by a membrane (also referred to as a diaphragm or porous separator in the case of an alkaline electrolyzer), which ensures electrical isolation between the two electrodes, gas separation, and ionic conduction within the electrolytic cell.
[0007] The insert has two functions: i) to provide a low-resistivity metal path between each bipolar plate and the associated electrode and ii) to allow proper circulation of the electrolyte solution to cool the electrolyzer cell and transport the generated gases.
[0008] The name “bipolar plate” comes from the fact that, because the electrolytic cells are all placed side by side, an N bipolar plate will have a potential that is:
[0009] - higher relative to the downstream bipolar plate N+1, so that the bipolar plate N will act as the anode in an electrolytic cell defined by the bipolar plates N and N+1;
[0010] - lower relative to the upstream bipolar plate N-1, so that the bipolar plate N will act as the cathode in an electrolytic cell defined by the bipolar plates N-1 and N.
[0011] The other metal parts, in addition to the bipolar plates, include the distribution plates (which make it possible to supply and distribute electricity to the electrolytic cells) and the base plates (which make it possible to define the set of electrolytic cells and ensure the tightening of said electrolytic cells and their sealing). Petition 870260045161, dated 05 / 13 / 2026, page 8 / 50 3 / 31
[0012] In fact, the electrolyzer stack ends in two base plates located just before the first electrolytic cell and just after the last electrolytic cell of the stack, that is, one base plate is located upstream of the block of electrolytic cells and the other base plate is placed downstream of it in order to physically define the two ends of said block of electrolytic cells.
[0013] The electrolyte solution present in each electrolytic cell, along with the gases produced by electrolysis (such as dihydrogen gas, dioxygen gas, chlorine gas, and halogen gas, etc.), must not leak over the edge of the diaphragm out of the electrolytic cell in question, but must circulate only through the dedicated pipes (where each pipe is dedicated either only to the electrolyte, or to the electrolyte mixed with one of the gases, taking into account that the two gases may also not be mixed with each other).
[0014] The electrolyzer cell therefore cannot operate continuously if a leak is observed, said leak originating from the electrolyte solution, from the gases generated by electrolysis, or from any other substance. This means that, in many cases, various problems with a negative impact on the environment and also on the safety of operators arise with varying degrees of severity, which can be significant and linked to irreversible consequences.
[0015] Conventionally, in an electrolytic cell as described herein, the assembly applied in order to prevent any leakage from the electrolyte solution, from the gas or gases generated by electrolysis and / or from any other substance, through the edge of the electrolytic cell diaphragm to the outside of said electrolytic cell, is based Petition 870260045161, dated 05 / 13 / 2026, page 9 / 50 4 / 31 in the use of a plurality of thin seals in the form of a sheet or a plurality of O-rings, often elastomeric, such that said seals or O-rings are positioned between the anode and cathode or the membrane of an electrolytic cell, or directly between two adjacent bipolar plates. The diaphragm is thus pressed between these different sealing elements.
[0016] Within the device, and particularly within the electrolyzer cell, various constituent elements intended to be in contact with the electrolyte are protected by a layer of nickel, commonly referred to as nickel plating. The purpose of applying a nickel layer is firstly to provide satisfactory corrosion resistance, and secondly to prevent dihydrogen and / or dioxygen from penetrating the aforementioned fundamental elements of the electrolyzer cell, and more particularly where protrusions occur. In other words, it is essential that said nickel layer be as uniform as possible in order to limit any leakage of dihydrogen and / or dioxygen, however small.
[0017] From a practical point of view, low nickel plating is detected by the presence of brownish spots within the aforementioned elements, or revealed by a copper sulfate test. In the second scenario, if copper sulfate adheres to the potentially nickel-plated location, this means that the nickel did not adhere correctly and effectively. In both scenarios, this verification is carried out during the manufacture of the various parts of the electrolyzer, in other words, when the different constituent elements of the electrolyzer are nickel-plated and assembled. Petition 870260045161, dated 05 / 13 / 2026, page 10 / 50 5 / 31
[0018] Among these elements, the bipolar plate plays an important role in the operation of the electrolyzer cell as previously explained. It is therefore essential that it undergoes the most perfect and uniform nickel plating possible during the overall assembly of the electrolytic cell, failure of which will reduce the efficiency of said electrolytic cell, while the above-defined defects will occur (corrosion and leakage of dihydrogen and / or dioxygen).
[0019] This nickel plating step of the bipolar plate, which is well known in the prior art, takes place in specific nickel baths. More specifically, the “virgin” bipolar plate is moved from a loading zone to a special nickel bath and is then transferred to an unloading zone.
[0020] Before plating, the bipolar plate is suspended from a bar by means of a hook. The bipolar plate is then immersed in the nickel plating bath and an electric current is applied to the bar. The electric current, through the hook, can thus pass through the bipolar plate, resulting in its nickel plating.
[0021] The nickel plating bath is currently formed by adding nickel pellets to a solution. For this, an operator discharges nickel pellets into a titanium basket, and the titanium basket is in turn moved so that it is immersed in the solution.
[0022] Because nickel is a very dense metal, an operator unfortunately has to manually unload bags containing small quantities of nickel pellets into the basket several times in order to fill it. Petition 870260045161, dated 05 / 13 / 2026, page 11 / 50 6 / 31
[0023] An operation like this is demanding for the operator and presents safety risks due to repeated discharge operations performed by the operator. This is because nickel pellets can escape during discharge, which can be dangerous for the operator (risk of falling, injury to the feet in particular, etc.).
[0024] An operation like this also requires a relative degree of precision, since the amount of nickel pellets discharged depends solely on the operator. OBJECT OF THE INVENTION
[0025] One objective of the invention is to propose a solution that makes it possible to overcome at least some of the aforementioned drawbacks. SUMMARY OF THE INVENTION
[0026] For this purpose, according to the invention, a filling carriage is provided, comprising: a chassis equipped with at least one container designed to hold pellets, at least one chute extending from inside the chassis to outside the chassis, wherein the chute extends towards the rear of the chassis, at least one means of transferring the pellets from the container into the chute during operation, at least one positioning sensor, wherein the sensor is oriented towards the rear of the chassis like the chute.
[0027] The cart in this form allows for faster and easier filling of at least one basket with pellets and, for example, with metal pellets and, for example, with nickel pellets. Petition 870260045161, dated 05 / 13 / 2026, p. 12 / 50 7 / 31
[0028] In particular, there is no need for an operator to manually unload the pellets onto the top of the basket; the pellets are lifted from the container into the basket by means of the transfer medium, and the chute then discharges the pellets directly into the basket.
[0029] Advantageously, the positioning sensor allows the cart to move more precisely with respect to the basket facing it, which contributes to faster and easier filling of the basket.
[0030] Hereafter, the terms “upper,” “lower,” “top,” “base,” etc., should be understood in relation to the operating position of the cart, that is, the position in which the cart is resting on the ground, ready to unload pellets into at least one basket.

[0034] Optionally, the detection sensor is arranged in the channel.
[0035] Optionally, the chute can be moved relative to the chassis between a rest position and a working position.
[0036] Optionally, the car comprises a system of at least one stop associated with the track in order to define its working position. Petition 870260045161, dated 05 / 13 / 2026, page 13 / 50 8 / 31
[0037] The invention also relates to an installation comprising at least one row of baskets and at least one car as previously mentioned, capable of moving relative to said row of baskets.
[0038] Optionally, the installation comprises a rail that extends along the row of baskets, in which the car cooperates with the rail in order to slide along the row of baskets.
[0039] Optionally, the installation includes a charging station capable of loading the car's container with pellets.
[0040] Optionally, the charging station is arranged at one longitudinal end of the row of baskets.
[0041] Optionally, the row of baskets is a first row of baskets, wherein the installation comprises a second row of baskets arranged in the opposite direction to the first row of baskets.
[0042] Optionally, the charging station comprises at least one upper hopper to which at least one outlet pipe is connected.
[0043] Optionally, the hopper is equipped with at least one cutting element.
[0044] Optionally, the charging station comprises a sensor to detect a fill level intended to detect the level to which the car has been filled with pellets discharged by the charging station.
[0045] Other features and advantages of the invention will become apparent from reading the following description of a particular, non-limiting embodiment of the invention. Petition 870260045161, dated 05 / 13 / 2026, page 14 / 50 9 / 31 invention. BRIEF DESCRIPTION OF THE DRAWINGS
[0046] Reference will be made to the attached drawings, in which: [Fig. 1] Figure 1 is a schematic perspective view of an installation according to a particular embodiment of the invention; [Fig. 2] Figure 2 is a perspective view of part of the installation shown in Figure 1; [Fig. 3] Figure 3 is a perspective view of another part of the installation shown in Figure 1. DETAILED DESCRIPTION OF THE INVENTION
[0047] With reference to figures 1 to 3, installation 1 according to a particular embodiment of the invention is at least configured to make it possible to fill at least one basket with pellets and, for example, with metal pellets and, for example, with nickel pellets.
[0048] In this case, installation 1 comprises at least a first row 2 of baskets 3 (where only part of the row is denoted by a reference sign in this document) intended to receive the pellets. The baskets 3 are, for example, made of titanium. The baskets 3 thus extend in succession one after the other in a first direction X. The first direction X is, for example, horizontal.
[0049] The first row 2 of baskets 3 comprises at least three baskets 3 and, for example, at least five baskets 3 and, for example, at least ten baskets 3 and, for example, at least fifteen baskets 3. The information given above is not limiting and the number of baskets 3 may therefore be different from that stated. Here, each basket 3 extends Petition 870260045161, dated 05 / 13 / 2026, page 15 / 50 10 / 31 longitudinally parallel to a second Y direction that is orthogonal to the first X direction. Here, each basket 3 extends vertically. The first Y direction is therefore vertical.
[0050] The different baskets 3 extend one after the other along the first X direction and parallel to each other.
[0051] Installation 1 further comprises at least one pellet loading station 4 and at least one first car 5 for filling the baskets 3 of the first row 2 with pellets.
[0052] Preferably, charging station 4 is arranged at one end of the first row 2 of baskets 3.
[0053] Also preferably, installation 1 is configured so that the first filling car 5 can move from charging station 4 to at least one of the baskets 3 in the first row 2 and preferably to the basket 3 in the first row 2 that is furthest from charging station 4.
[0054] For example, the first filling car 5 is arranged in the installation 1 so that it can slide along the first row 2. For example, the installation 1 comprises a first rail 6 that rests on the ground, on which first rail 6 the first filling car 5 is received in a sliding manner. Preferably, the loading station 4 is arranged at a longitudinal end of the first rail 6.
[0055] The first rail 6 is arranged along the first row 2. The first row 2 thus forms an edge of the first rail 6. The first rail 6 extends, Petition 870260045161, dated 05 / 13 / 2026, page 16 / 50 11 / 31 for example, parallel to the first X direction.
[0056] The first fill car 5 can thus slide parallel to the first X direction from right to left and vice versa.
[0057] The first filling car 5 can thus slide along the first row 2 between a first end position in which the first filling car 5 is level with the charging station 4 and a second end position in which the first filling car 5 is level with the basket 3 of the first row 2 that is furthest from the charging station 4.
[0058] The movement of the first filling car 5 along the first row 2 is optionally motorized by at least one actuation system and / or is performed by an operator.
[0059] Preferably, installation 1 is at least configured to enable filling at least a second row 7 of baskets 8 (only part of which is denoted by a reference sign in this document) with pellets and, for example, with metal pellets and, for example, with nickel pellets.
[0060] Installation 1 then comprises at least a second row 7 of baskets 8 designed to receive the pellets. The baskets 8 are, for example, made of titanium. The baskets 8 thus extend in succession one after the other in the first direction X. The second row 7 extends, however, in the opposite direction to the first row 2 with respect to the loading station 4. The first row 2 and the second row 7 are thus symmetrical with respect to the loading station 4 along a geometric axis of symmetry. Petition 870260045161, dated 05 / 13 / 2026, page 17 / 50 12 / 31 orthogonal defined in the second Y direction. In this document, the orthogonal geometric axis of symmetry extends vertically.
[0061] The second row 7 comprises at least three baskets 8 and, for example, at least five baskets 8 and, for example, at least ten baskets 8 and, for example, at least fifteen baskets 8. The information given above is not limiting and the number of baskets 8 may therefore be different from that stated. In this document, each basket 8 extends longitudinally parallel to the second direction Y. In this document, each basket 8 extends vertically.
[0062] The different baskets 8 extend one after the other along the second X direction and parallel to each other.
[0063] Installation 1 additionally comprises at least one second car 9 for filling baskets 8 in the second row 7 with pellets.
[0064] Preferably, charging station 4 is arranged at one end of the second row 7.
[0065] Also preferably, installation 1 is configured so that the second filling car 9 can move from charging station 4 to at least one of the baskets 8 in the second row 7 and preferably to the basket 8 in the second row 7 that is furthest from charging station 4.
[0066] For example, the second fill car 9 is arranged in the installation 1 so that it can slide along the second row 7. For example, the installation 1 comprises a second rail 10 that rests on the ground, on which second rail 10 the second fill car 9 is received in a sliding manner. Petition 870260045161, dated 05 / 13 / 2026, page 18 / 50 13 / 31 Preferably, charging station 4 is arranged at one longitudinal end of the second rail 10.
[0067] The second rail 10 is arranged along the second row 7. The second row 7 thus forms an edge of the second rail 10. The second rail 10 extends, for example, parallel to the first X direction.
[0068] The second fill car 9 can thus slide parallel to the first X direction from right to left and vice versa.
[0069] The second filling car 9 can thus slide along the second row 7 between a first end position in which the second filling car 9 is level with the charging station 4 and a second end position in which the second filling car 9 is level with the basket 8 of the second row 7 that is furthest from the charging station 4.
[0070] The movement of the second fill car 9 along the second row 7 is optionally motorized by at least one actuation system and / or is performed by an operator.
[0071] As the second row 7 extends in the opposite direction to the first row 2, the charging station 4 is located between the two rows 2, 7.
[0072] Installation 1 as described has a central charging station 4 and, on each side of the same 4, rows 2, 7 of baskets 3, 8 each 2, 7 one of which is respectively associated with a filling car 5, 9.
[0073] Charging station 4 will now be described.
[0074] Charging station 4 comprises a Petition 870260045161, dated 05 / 13 / 2026, page 19 / 50 14 / 31 Hopper 11 arranged at the top of loading station 4. The top of hopper 11 is either completely open or partially open. The intake of hopper 11 is thus defined by this opening. As a result, pellets can be discharged into hopper 11 from the top of loading station 4 (and therefore from the top of hopper 11).
[0075] Hopper 11, for example, is shaped like a funnel, which narrows along the Y direction, but in the opposite direction, in other words, towards the ground.
[0076] Hopper 11 additionally comprises at least one outlet, and in that case, comprises at least two outlets.
[0077] Each outlet is associated with one of the rows 2, 7 on one side and the other of the hopper 11, respectively. For example, each outlet is formed in the shape of a pipe 12 that extends from the hopper 11 towards one of the rows 2, 7, respectively.
[0078] For example, each pipe 12 is formed in the shape of a closed channel that emerges at one end into the hopper 11 and emerges at the other end level with one of the rows 2, 7, respectively.
[0079] For example, each barrel 12 has an elbow. For example, each barrel 12 comprises a first section 13a that extends at an angle in a straight line between its first end and the elbow. The first end emerges, for example, at the bottom of the hopper 11. For example, each barrel 12 comprises a second section 13b that extends in a straight line from the elbow to the second end of the barrel 12, wherein Petition 870260045161, dated 05 / 13 / 2026, page 20 / 50 15 / 31 The second section 13b extends transversely or perpendicularly to the first section 13a. Preferably, the second section 13b extends vertically (i.e., here parallel to the second Y direction) with the second end facing the ground. Preferably, the installation 1 is configured so that, when each filling car 5, 9 is in its first end position, the second end of the associated pipe 12 emerges above a container 16 of said filling car 5, 9. The pellets are thus discharged into the filling car 5, 9 initially obliquely and then vertically from the pipe 12 depending on the discharge speed of the pellets.
[0080] Preferably, the two pipes 12 extend symmetrically on either side of the hopper 11 along at least one geometric axis of symmetry. Said geometric axis of symmetry is, for example, vertical. Said geometric axis of symmetry passes, for example, through the center of the hopper 11 and / or the loading station 4. This configuration is similar to one previously described with respect to the respective positions of rows 2, 7.
[0081] Preferably, the loading station 4 comprises at least one cutting element 14. Said cutting element 14 is, for example, arranged in the hopper 11 and, for example, inside the hopper 11. Said cutting element 14 is, for example, arranged along one of the side walls of the hopper 11 and / or in the center thereof 11 and / or above the first end of at least one of the pipes 12. Said cutting element 14 is, for example, a sharpened member such as, by way of non-limiting example, a serrated blade. Optionally, two cutting elements 14 may Petition 870260045161, dated 05 / 13 / 2026, page 21 / 50 16 / 31 can be arranged in hopper 11, for example, on opposite walls of hopper 11.
[0082] Preferably, the charging station 4 is equipped with at least one detection sensor 15. Said detection sensor 15 is, for example, a sensor for detecting the fill level of the container 16 of the associated filling car 5, 9. For example, the detection sensor 15 is an optical sensor. For example, the detection sensor 15 directs a measuring beam to the bottom of the container 16, which makes it possible to estimate the fill level of the container 16. For example, the measuring beam extends along at least one geometric axis which is optionally vertical.
[0083] Preferably, said detection sensor 15 is held by one of the pipes 12. For example, each of the pipes 12 is fitted with a detection sensor such as this 15 in order to estimate the filling level of the associated filling carriage 5, 9. The filling carriages 5, 9 are thus arranged in their first end positions so that their containers 16 extend below the beam of the detection sensor 15 facing them so that said detection sensor 15 can reach the bottom of the container 16.
[0084] One of the 5, 9 fill cars will now be described. Here, the two 5, 9 fill cars are identical, and the following description of the first 5 fill car also applies in this document to the second 9 fill car. This application is certainly not limiting, and there may be two different 5, 9 fill cars within the same installation 1.
[0085] The first filling car 5 comprises a chassis 17 fitted with a container 16 arranged Petition 870260045161, dated 05 / 13 / 2026, p. 22 / 50 17 / 31 on the top of chassis 17. The top of container 16 is either completely open or partially open. The intake of container 16 is thus defined by this opening. As a result, pellets can be discharged into container 16 from the top of the first filling car 5 (and therefore from the top of container 16).
[0086] Container 16 is, for example, funnel-shaped, narrowing along the Y direction, but in the opposite direction, in other words towards the ground. Container 16 additionally extends substantially parallel to the Y direction.
[0087] The first filling car 5 further comprises at least one means 18 for transferring the pellets from the container 16 to a chute 19 of the first filling car 5. The transfer means 18 is, for example, a vibrating tube or a screw transfer device. For example, the transfer means 18 is an auger or an Archimedes screw.
[0088] Here, the transfer medium 18 extends from the container 16 towards the first row 2. Preferably, the container 16 is situated in front of the first filling car 5 and the transfer medium 18 in the rear of the first filling car 5 between the container 16 and the first row 2.
[0089] Preferably, the transfer medium 18 is motorized. For this purpose, the first filling carriage 5 comprises at least one actuator of the transfer medium 18. The actuator is, for example, a motor that rotates the transfer medium 18. Petition 870260045161, dated 05 / 13 / 2026, page 23 / 50 18 / 31
[0090] As already stated, the first filling carriage 5 comprises a chute 19 associated with the transfer medium 18.
[0091] For example, channel 19 has an upper end connected to the transfer medium 18 and a lower end that extends above the first row 2.
[0092] Preferably, channel 19 is formed in the shape of a closed channel that emerges at its two lower and upper ends.
[0093] For example, chute 19 has an elbow. For example, chute 19 comprises a first section 20a that extends obliquely in a straight line between its upper end and the elbow. For example, chute 19 comprises a second section 20b that extends in a straight line from the elbow to the lower end of chute 19, wherein the second section 20b extends transversely or perpendicularly to the first section 20a. Preferably, the second section 20b extends vertically (i.e., here parallel to the second Y direction) with the second opening facing the ground. The second section 20b additionally extends substantially parallel to the Y direction, but in the opposite manner, in other words, towards the ground. The pellets are thus discharged into basket 3 facing chute 19, vertically from chute 19.
[0094] In this document, chute 19 extends from the first filling car 5 towards the first row 2. Preferably, container 16 is located in front of the first filling car 5 and chute 19 behind the first filling car 5 between the Petition 870260045161, dated 05 / 13 / 2026, page 24 / 50 19 / 31 container 16 and the first row 2.
[0095] Preferably, the first filling car 5 is equipped with at least one detection sensor 21. Said detection sensor 21 is, for example, a sensor 21 for detecting the filling level of basket 3 facing the first filling car 5. For example, the detection sensor 21 is an optical sensor. For example, the detection sensor 21 directs a measuring beam to the bottom of basket 3 in question, which makes it possible to estimate the filling level of said basket 3. For example, the measuring beam extends along at least one geometric axis which is optionally vertical. Preferably, said detection sensor 21 is held by the channel 19.
[0096] Furthermore, the first filling car 5 comprises at least one positioning sensor 22. The positioning sensor 22 is, for example, a sensor for detecting the positioning of the first filling car 5 relative to the first row 2. Said positioning sensor 22 is, for example, a sensor for detecting the presence of at least one characteristic element of a basket 3 such as an upright M of a basket 3 (the upright M enabling the basket 3 to be attached to a support such as, for example, a bar B as described below), wherein only some of the uprights are denoted by a reference sign in this document. For example, the positioning sensor 22 is an optical sensor. For example, the sensor directs a measuring beam towards the first row 2, which makes it possible to estimate the relative position of the first filling car 5 and at least one of the baskets 3 of the first row 2. For example, the measuring beam extends along Petition 870260045161, dated 05 / 13 / 2026, p. 25 / 50 20 / 31 of at least one geometric axis that is optionally horizontal.
[0097] Furthermore, the first filling car 5 comprises at least one positioning sensor 23. The positioning sensor 23 is, for example, a sensor for detecting the positioning of the first filling car 5 relative to the first row 2. Said positioning sensor 23 is, for example, a sensor for detecting the presence of at least one characteristic element of a basket 3, such as, for example, the upright of a basket 3. For example, the positioning sensor 23 is an optical sensor. For example, the positioning sensor 23 directs a measuring beam towards the first row 2, which makes it possible to estimate the relative position of the first filling car 5 and at least one of the baskets 3 of the first row 2. For example, the measuring beam extends along at least one geometric axis which is optionally horizontal.
[0098] Preferably, the two positioning sensors 22, 23 are arranged so that one detects the upright and the other detects the left upright of the same basket 3 when the first filling carriage 5 is facing said basket 3. This ensures that the first filling carriage 5 is correctly centered with respect to said basket 3. In particular, when each of the positioning sensors 22, 23 detects an upright of the same basket 3, the chute 19 extends above the basket 3 in question, and, for example, a few centimeters above the basket 3 in question, being centered with respect to said basket 3.
[0099] Preferably, channel 19 can be Petition 870260045161, dated 05 / 13 / 2026, page 26 / 50 21 / 31 extended on the first filling carriage 5 between a rest position in which said chute 19 is at a distance from the first row 2 and a working position in which its second end extends above the baskets 3. For example, the chute 19 moves from its rest position to its working position in an extension direction Z that is orthogonal to the first direction X and the second direction Y. For example, said extension direction Z is horizontal.
[0100] The chute 19 moves between its rest position and its working position, for example, by translation and / or rotation and / or telescopic movement of the chute 19. Preferably, the transfer means 18 remains fixed in relation to the chassis 17. The extension of the chute 19 makes it possible to manage the distance between the first filling carriage 5 and the first row 2.
[0101] This extension of chute 19 is preferably motorized. The extension of chute 19 is controlled automatically and / or manually. For this purpose, the first filling carriage 5 may be fitted with at least one button 24 to control the extension of chute 19, which control button 24 is arranged on the front face of the chassis 17 (i.e., on the opposite side of the face of the chassis 17 facing the first row 2). Preferably, the first filling carriage 5 is fitted with at least two buttons 24 to control the extension of chute 19, which control buttons 24 are arranged on the front face of the chassis 17 and on opposite edges of said front face of the chassis 17. This makes it possible to increase the safety of the assembly, since the operator has to simultaneously activate both control buttons 24 in order to extend or retract the chute 19.
[0102] Preferably, the first car of Petition 870260045161, dated 05 / 13 / 2026, page 27 / 50 22 / 31 filling 5 comprises at least one system of at least one stop to define at least one of the rest and work positions of the trough 19. Preferably, the system comprises at least one stop to define the work position of the trough 19. Preferably, the system comprises at least two stops 25a, 25b to define the work position of the trough 19.
[0103] For example, each of the stops 25a, 25b is rigidly connected to the track 19 for movement with it in such a way that the stops 25a, 25b extend towards the first row 2 with the track 19. The stops 25a, 25b therefore move towards the first row 2 in at least one translational movement in the third direction Z.
[0104] When the stops 25a, 25b each come into contact with one of the respective uprights of the basket 3 in question, the extension of the chute 19 is interrupted, and the chute 19 is in its working position. The extension can be interrupted manually and / or automatically. For example, an indicator light and / or an audible indicator, preferably arranged on the first filling carriage 5, can be activated. This makes it possible to inform the operator that the chute 19 is in its resting position and that they can therefore stop the extension of the chute 19 (for example, by releasing the buttons 24).
[0105] Preferably, the free end of at least one of the stops 25a, 25b (i.e., the end intended to come into contact with one of the uprights of the basket 3 in question) is provided with an elastically deformable element (pad, spring, etc.). The said elastically deformable element is thus compressed in the associated upright when the track 19 is Petition 870260045161, dated 05 / 13 / 2026, page 28 / 50 23 / 31 in your work position.
[0106] Optionally, the deformation of said elastically deformable element is continuously measured (for example, by at least one sensor held by the first filling carriage 5, such as a force sensor, for example), and, as soon as the force experienced by the elastically deformable element reaches a threshold value, a signal is generated to stop the extension of the chute 19.
[0107] Installation 1 is preferably used to fill baskets 3 with pellets and, for example, metal pellets and, for example, nickel pellets, so that said pellets can be used in one or more electroplating baths. The electroplating bath or baths is / are, for example, used to electroplate one or more parts and, for example, one or more parts of an electrolyzer cell and, for example, one or more bipolar plates.
[0108] Furthermore, each row 2, 7 of baskets 3, 8 is arranged in such a way that all the baskets 3, 8 of said row 2, 7 are fixed (by means of their uprights) to the same anode bar B. When the bar is placed in a treatment bath (for example, by a robot), it thus takes the entire row of associated baskets 3, 8 with it.
[0109] Note that the two bars B arranged to the right and left of charging station 4 are not symmetrical along a vertical geometric axis of symmetry passing through the center of installation 1 (here passing through the center of charging station 4). This is attributed in particular to the fact that baskets 3 and 8 are mounted in different orientations on the same bar B. In reality, for the same bar B, baskets 3 and 8 are arranged in a succession. Petition 870260045161, dated 05 / 13 / 2026, p. 29 / 50 24 / 31 of baskets “on the left side” (defining a first orientation with respect to bar B) and a succession of baskets “on the right side” (defining a second orientation with respect to bar B). B) Similarly, reference can thus be made to a bar on the right side B and a bar on the left side B in installation 1.
[0110] During operation, an operator deposits a bag of pellets into hopper 11. A bag like this typically weighs approximately one ton or even more. A bag like this is, for example, deposited into hopper 11 by means of a crane, for example, or any other lifting means.
[0111] When the pellet bag comes into contact with at least one cutting element 14, the bottom of said pellet bag is opened by cutting, and the pellets fill the hopper 11.
[0112] Preferably, the first ends of the right and left side pipes 12 are associated with valves that make it possible to temporarily prevent access to the right and left side pipes 12. For example, at least one of the valves comprises a disc that is fixed relative to the hopper 11 and a disc that is rotationally mounted relative to the fixed disc. The two discs are perforated so that, depending on the relative positions of the fixed disc and the rotationally mounted disc, the holes in the discs are aligned (allowing access to the associated pipe) or the holes are offset (preventing access to the associated pipe).
[0113] If one of the filling cars 5, 9 is placed in its first end position (for example, the first filling car 5), the valve of the associated pipe 12 is then opened and the pellets are discharged from the hopper 11 into Petition 870260045161, dated 05 / 13 / 2026, p. 30 / 50 25 / 31 pipe 12 and then into container 16 of the first filling car 5. The valve can be opened automatically (for example, after sending a signal from the detection sensor 15 to detect the presence of the first filling car 5) or manually.
[0114] Discharge ceases when the target fill level is reached. It can be stopped automatically (e.g., after a signal is sent from the detection sensor 15) or manually (e.g., after a light and / or audible signal is emitted based on a signal generated by the detection sensor 15). For this, the valve associated with the pipe 12 in question is closed.
[0115] The first fill car 5 is then moved along the first rail 6.
[0116] When the positioning sensors 22, 23 detect that the first filling car 5 is facing one of the baskets 3 of the first row 2 associated with the first filling car 5 (preferably, the basket 3 of the first row 2 that is closest to the charging station 4), the first filling car 5 is automatically immobilized in the position relative to said first row 2.
[0117] The operator then requests the extension of chute 19 by pressing the control buttons 24. When the indicator is activated (meaning that the stops 25a, 25b are in place against the uprights), the operator stops the extension of chute 19. Note that the stops 25a, 25b make it possible to ensure that chute 19 is correctly positioned in relation to basket 3 in question and / or that chute 19 is correctly stabilized in position in relation to basket 3. Petition 870260045161, dated 05 / 13 / 2026, page 31 / 50 26 / 31
[0118] Hence, the pellets are discharged from container 16 of the first filling car 5 into basket 3 by means of the transfer means 18. The transfer means 18 therefore makes it possible to lift the pellets from container 16 to chute 19. For example, the pellets fall by gravity from the transfer means 18 into chute 19.
[0119] Discharge ends when the target fill level is reached. It can be stopped automatically (e.g., after a signal is sent from fill sensor 21) or manually (e.g., after a light and / or audible signal is emitted based on a signal generated by fill sensor 21). For example, when the indicator is activated, the operator can then stop the pellet discharge and control the retraction of chute 19 so that said chute 19 returns to its rest position.
[0120] Then, the first filling car 5 is mobilized (manually or automatically) and is thus moved again along the first rail 6 until its positioning sensors 22, 23 detect the uprights of the adjacent basket 3 and again cause the first filling car 5 to come to a stop.
[0121] The steps described above are then repeated with the new basket 3.
[0122] Due to this translation of the first filling car 5, it is possible to individually feed each basket 3 of the first row 2 one after the other until all baskets 3 of the first row 2 have been filled with pellets.
[0123] It is understood that the description presented with reference to the first filling car 5 and the first Petition 870260045161, dated 05 / 13 / 2026, page 32 / 50 27 / 31 row 2 also applies to the second filling car 9 and the second row 7.
[0124] Installation 1 as described is more ergonomic for the operator, who in particular does not need to fill baskets 3, 8 with pellets manually.
[0125] Installation 1 as described makes it possible to increase the rate at which baskets 3, 8 are filled and / or increase the dimensions of baskets 3, 8 and / or increase the mass of pellets that fill each basket 3, 8 compared with prior art devices.
[0126] As a result, installation 1 as described allows anode bars B to be placed more regularly in the treatment baths, which also makes it possible to increase the rate at which the parts are electroplated.
[0127] Installation 1 as described also makes filling baskets 3, 8 safer. In particular, baskets 3, 8 are no longer filled manually, which limits the risk of pellets overflowing in basket 3, 8.
[0128] Installation 1 as described also makes it possible to reduce the cost of pellets lost for the same reason presented in the previous point.
[0129] Preferably, installation 1 comprises the electrogalvanizing baths.
[0130] Installation 1 thus comprises one or more robots that transport the anode bars B (maintaining rows 2 and 7) to one of the electroplating baths. The robot or another robot also transports the part to be treated, which is in turn suspended on a cathode bar.
[0131] Within electrogalvanizing baths, the Petition 870260045161, dated 05 / 13 / 2026, page 33 / 50 The 28 / 31 part to be treated is thus flanked by a left-side anode bar B on one side and a right-side anode bar B on the other side.
[0132] From this moment on, the electrolytic galvanizing of the part begins with the injection of a given amount of electric current into the anode bar B. As the electrolytic galvanizing of the part progresses, there is a reduction in the number of pellets present in each basket 3, 8 attached to the respective anode bar B. This number of pellets consumed in each basket 3, 8 is directly linked to and proportional to the amount of electric current passing through the associated anode bar B.
[0133] A control unit associated with the treatment bath thus estimates the amount of pellets consumed in each basket 3, 8 over time and activates a signal when a threshold of a minimum amount of pellets present in each basket 3, 8 is reached.
[0134] After that, a robot removes the defective anode bar B from the treatment bath in order to transport it to charging station 4 again.
[0135] This deficient anode bar B associated with its row of baskets 3, 8 is then recharged according to the steps described herein.
[0136] Simultaneously, a robot will reach an anode bar B in which baskets 3, 8 are already loaded with pellets. This makes it possible to continue treating a part. Installation 1 in this way makes it possible to limit the time spent on electrogalvanizing a part as much as possible.
[0137] It is understood that each installation 1 comprises a plurality of charging stations 4 or the installation Petition 870260045161, dated 05 / 13 / 2026, page 34 / 50 29 / 31 is configured so that a loading station 4 makes it possible to continuously fill rows 2 and 7, wherein said rows 2 and 7 are stored as they are filled in a storage zone adjacent to the installation.
[0138] Certainly, the invention is not limited to the embodiment described, but encompasses any variant that falls within the scope of the invention defined by the claims.
[0139] For example, the installation may comprise only one row of baskets, or more than two rows.
[0140] A single car can be associated with more than one row of baskets. For example, a single car can fill two rows of baskets, where the two rows of baskets are optionally arranged on either side of the charging station.
[0141] Although the movement of the cars is automated here, the movement of at least one of the cars may be manual. At least one of the cars may thus comprise at least one handle by means of which the operator can slide the car on the track. Preferably, in this case, said car comprises two handles, each of which handles is arranged on opposite side walls of the car chassis. Preferably, in this case, the handles are arranged on the upper part of said side walls. Preferably, said handles are arranged symmetrically on the chassis along at least one geometric axis of symmetry. Said geometric axis of symmetry is, for example, vertical. Said geometric axis of symmetry passes, for example, through the center of the car. Preferably, said handles are thus arranged at the same height relative to the ground in order to improve ergonomics. Petition 870260045161, dated 05 / 13 / 2026, page 35 / 50 30 / 31 of the car.
[0142] At least one of the pipes may be fitted with at least one presence sensor that makes it possible to estimate whether or not the car associated with the pipe is in the first final position. If the car is detected, the pipe is not open.
[0143] Although here the pipe has a sensor to detect the fill level of the associated container, it is possible that the car itself has such a sensor. Alternatively, or additionally, it can be considered that the operator estimates the fill level of the container on his own.
[0144] Although here the chute contains a sensor to detect the fill level of the associated basket, it is possible that the basket itself has such a sensor. Alternatively, or additionally, it can be considered that the operator estimates the fill level of the basket on its own.
[0145] The cart can only be moved if the target fill level of the basket has been reached or if the cart's container is empty. The cart's container may be fitted with a sensor that makes it possible to detect the fill level of the container (and, in particular, to detect if the container is empty).
[0146] Although some of the steps described here are performed manually, all the steps described can be performed automatically.
[0147] The installation may, for example, comprise at least one control unit that controls the movement of at least one carriage facing at least one row of baskets and / or that controls the means of transfer in order to Petition 870260045161, dated 05 / 13 / 2026, page 36 / 50 31 / 31 interrupt or activate it.
[0148] The pellets may be made of a material other than that stated and, for example, may be made of a metallic material and, for example, be made of or based on brass, cadmium, chromium, copper, other, iron, silver, titanium, zinc, etc., or any other material that can be used to form an electroplating bath (the nickel plating bath described in this way is not limiting).
