Description

The present invention relates to a modular tool storage system. The present invention was born in the field of aeronautical maintenance but can be extended to the field of industrial maintenance in general. When a technician, or a team of technicians, is called upon to intervene on a site, for example a broken aircraft, he takes with him the equipment necessary for the intervention. Depending on the intervention to be made, he chooses his tools that he carries with him. At this level, several problems arise. Some are more specific to the aeronautical field but others are problems that are also found in the field of industrial maintenance in general. In the aeronautical field, the regulations require demonstrating that all the tools used during an airplane project have been inventoried and that no tool has been forgotten in the aircraft. When selecting the tools carried, it is advisable to ensure that the tools available on the site and the tasks to be carried out on the site are as perfect as possible. It is advisable here to avoid carrying too much tools but it is not necessary to miss tools during the maintenance operation carried out. Indeed, it is necessary to avoid on one side to ship and immobilize unnecessary tools and on the other hand, in case of lack of tools on the site, to return tools in a hurry. It is therefore necessary to be effective by carrying all the necessary tools while limiting unnecessary expenses in terms of costs.

The tools carried can be arranged in bulk in a box. A box of this type is commonly used by the personnel in charge of the maintenance or the interventions on the sites of implementation of mechanical devices, electrical, ... Such a box is normally constituted of a rigid body, generally in material synthetic or metallic, with carrying handles or a strap to carry it to the shoulder. Such a box is poorly suited to the storage of strictly necessary equipment, sometimes providing space and especially unnecessary overweight and penalizing with regard to handling or transport constraints. In addition, the absence of a specific storage system prevents easy and quick recognition of the tools included in the box, and consequently, does not allow the identification of tools that may be missing at the end of the project. In addition, the unstructured storage of tools in the box prevents the user from immediately finding the items stored there. Finally, such a box usually contains a maximized set of tools for autonomously performing all the tasks relating to the activity of its owner. The lack of flexibility in managing the content of such a box does not allow this content to be adapted simply and quickly to specifically match the task at hand. To solve some problems mentioned above, it is known to adapt in a box for receiving bulk tools, storage modules, usually made of rigid metal or plastic lockers. This improves the organization of storage in the box by separating the different tools. This solution leads to a reduction in the size of each space available for storage and complicates the storage of the largest tools. In addition, the presence of modules increases the weight of the container at the expense of the tool. This weight constraint is important when the technician uses the airplane as a means of transport to intervene on the site. In the field of aeronautical maintenance, it is known to use boxes composed of storage lockers. The box itself is made of metal or synthetic material. Inside the crate are stacked storage lockers. In each case, there is a block of rigid foam in which cavities are machined to the shape of the tools they are intended to contain. Such a system makes it possible to simplify the identification of the tools that may be missing at the end of the construction site. However, it has the same disadvantages as bulk crates, with or without storage lockers. Indeed, the proposed tooling lists are fixed and defined by the supplier so as to cover a general and non-specific activity. This does not solve the constraint of adequacy between the proposed tools and the tools actually required by the maintenance task to be performed. So we do not necessarily find the type of tool required, or the amount of tooling desired. Finally, this system of pre-arranged boxes does not take into account the weight constraint related to the air transport of the crate in accompanied luggage.

The present invention therefore aims to provide the means for carrying out a given maintenance operation, to carry the appropriate tools and a suitable amount of tools. For this purpose, the present invention relates to a modular tool storage system.

According to the present invention, this system comprises: a set of tools intended to be used for carrying out different types of tasks, each tool belonging to a subset corresponding to a given type of task or to a subset of tools grouping tools common to the execution of several types of tasks, presentation devices for several tools all belonging to the same subset of tools, several presentation devices having similar external dimensions, containers of different predefined sizes, each container being intended to receive one or more tools presentation devices.

This system is a modular system in two directions: first it has a functional modularity and then it has a quantitative modularity. Functional modularity is achieved through the creation of subsets of tools corresponding to tasks of predefined types. Quantitative modularity is achieved by containers of various predefined sizes allowing to carry the necessary quantity of tools. For greater standardization, the modular system according to the present invention provides that all the presentation devices preferably have the same external dimensions. We then have standard size presentation devices: this allows standardization also containers whose size can be adapted to receive all the presentation devices. According to a preferred embodiment of a modular system according to the invention, each presentation device comprises a foam block in which cavities are formed, each intended to receive a tool. Such presentation devices are of a negligible weight compared to the weight of the tools it contains and allows to ensure the protection of tools during transport. To facilitate the handling of the presentation devices, stiffening elements in the form of a plate on which a block of foam and at least two holding flanges each extending along one side can be provided. foam block. The foam blocks are then perfectly maintained and can be moved like a rigid box. An alternative solution is to provide suitcases each adapted to contain a foam block. In the same system, it may be both stiffeners and suitcases according to the containers provided for the transport of the presentation devices. To facilitate the management of the stock of tools, each tool is advantageously provided with a barcode, and each tool presentation device is also provided with a barcode. According to a preferred variant embodiment, such a modular system further comprises: a dedicated computer system for managing the inputs / outputs of the tools of a store, and a barcode reading system connected to the dedicated management computer system. In the computer system of this modular system, each tool and each presentation device advantageously comprise an own identifier, and all the identifiers of the tools of a presentation device are associated with the identifier of said presentation device. Such a management system makes it possible to quickly record input and output movements. You only need to register the identifiers of the presentation devices by reading the corresponding barcode to know all the tools that enter or leave the tool magazine. It is then unnecessary to read a barcode on each tool to make recordings of 30 tool movements. This saves a lot of time. Finally, such a system preferably further comprises a transport document editing device to be able to automatically edit a list of tools entering or leaving the tool magazine. Details and advantages of the present invention will emerge more clearly from the description which follows, made with reference to the attached schematic drawings in which: FIG. 1 schematically shows various categories of tools for the aeronautical field, FIG. 2 represents quantitative levels of Figure 3 shows schematically in perspective a tool storage module, Figure 4 schematically shows a tool for storing tools, Figure 5 is a sectional view of a detail of a module of a tool. 6A shows a toolbox in side view, FIG. 6B shows the toolbox of FIG. 6A in open position, FIG. 6C shows the inside of the box of FIGS. 6A and 6B in view. 6D is a sectional view along section line VI-VI of FIG. 6C; FIG. 7 shows a front view of a mobile workshop, and FIG. 8 is an example of a module and FIG. tools that it can contain. The tool management system described below is a modular system with two axes: it has functional modularity on the one hand and quantitative modularity on the other. Functional modularity is achieved through tool storage modules containing tools according to predefined tooling lists depending on the type of tasks to be performed. Quantitative modularity is obtained by matching the quantity of tools provided according to the volume of work to be performed, and therefore the size of the intervention team. Advantageously, the present invention proposes that the modules used are all of the same size, whatever their type. These modules are then put in containers adapted to their number and the constraints related to their transport on the site of a construction site, for example a shipyard. This description is now made with reference to the aeronautical field. However, the present invention could be implemented in a different field, for example industrial maintenance in general, when for example it is expedient to ship tools to a construction site. In the field of aeronautical maintenance, the tasks to be performed can be classified in three categories: • systems: these are tasks related more specifically to the maintenance of aircraft systems. These tasks concern, for example, landing gear, air conditioning, etc. • structure: these tasks are related to the maintenance, repair or modification of the structure of an aircraft. This involves, for example, a change of an external panel, the reinforcement of a structural element such as a frame, ... • electrical: these tasks concern the maintenance of the electrical circuits of the aircraft, the wiring of this one, the connectors, ... Special tools are necessary for the realization of the tasks of each of these three categories. However, there are also common tools, which can be called basic tools, which are necessary to perform the tasks of the three categories mentioned above. Figure 1 shows schematically the set of tools according to their categories. The subset SYS corresponds to the tools to perform tasks of the category "systems". Likewise, the subset STR corresponds to the tools used to carry out tasks of the "structure" category and the subset ELC contains the tools intended to perform tasks of the "electrical" category. The COM subset contains the basic tools that are useful for carrying out the tasks of the three categories mentioned above. As mentioned above, each tool is stored in a storage module. In the same storage module, there are only tools belonging to the same subset (SYS, STR, ELC or COM). The definition of the content and the organization of each storage module are optimized so as not to duplicate the common tools made available to the response team. As an illustrative example, if a maintenance operation consists of performing tasks in the "structure" category and the "systems" category, the intervention team will be provided with several modules, some modules containing STR subsystem tools, other modules with tools from the SYS subset, and finally other modules with tools from the COM subset. The classification of tools in subassemblies makes it possible to obtain functional modularity when preparing tools to perform a maintenance task on an aircraft. The present invention also provides a quantitative modularity to match the volume of tools made available to the intervention team to the size of this intervention team which itself depends on the size of the site to achieve.

According to a preferred embodiment, adapted to the field of aeronautics, three quantitative levels are defined. A first level, or level 1, corresponds to the minimum of tools required on site to perform basic troubleshooting or small repairs. This level is intended for a vacation of one or two people. Level 1 is the minimum of tools required to perform a maximum of tasks. A second level, or level 2, corresponds to the quantity required on site to perform a qualified intervention standard, for which a team of two to four people intervenes. Finally, a third level, or level 3, corresponds to the quantity of tools necessary for the on-site execution of a major maintenance operation, such as, for example, for a heavy structural repair. The quantity of tools corresponding to this level is suitable for the intervention of a team of more than five people. These three levels are nested inside one another. Thus, each level consists of a superset of the lower level and comes in addition to it, both in terms of type of tooling and quantity. Figure 2 illustrates the three levels described above. Figure 3 schematically shows a storage module according to the invention. As indicated above, in a system according to the invention, all the storage modules have the same dimensions. It will be noted in FIG. 2 that the storage module shown diagrammatically comprises, on the one hand, a block of foam 2 and, on the other hand, a stiffening element, hereinafter referred to as a stiffener 4. The foam block 2, in one embodiment favorite, features

an upper layer 6 made of a dark-colored foam and a lower layer 8 made in a light color. By way of non-limiting example, the dimensions of a block of foam are for example the following: 460 mm x 380 mm x 60 mm. The upper layer 6 is for example anthracite gray in color and measures: 460 mm x 380 mm x 5 mm. The lower layer 8 is, for example, yellow in color and has, for example, dimensions of: 460 mm × 380 mm × 55 mm. The upper layer 6 and the lower layer 8 are for example glued together to form a monolithic block. As can be seen in Figures 5 and 8, cavities 10 are machined in the upper face of the foam block 2, each of these cavities 10 being intended to accommodate a tool 12. The opening of each cavity for introduction of the tool 12 is thus made at the level of the upper layer 6 while the bottom of the cavity is in the lower layer 8. In this way (see Figure 8), it is very easy to identify the cavities 10 in which is a tool 12 and the cavities without tools. We quickly identify the missing tools, potentially forgotten on the site. The cavities 10 are machined in such a way that the corresponding tool 12 fits perfectly into the foam thus ensuring the lateral setting of the tool 12 during a transport. As illustrated in FIG. 5, an additional cavity 14 is machined in the bottom of each cavity 10 to facilitate removal of the tool 12 from the cavity 10. If it is supposed that the upper face of the foam block 2 is horizontal, this upper face corresponding to the face of the foam block 2 formed only by the upper layer 6 of dark color, then the additional cavities 14 are formed at the bottom of the cavities 10 by a machining performed vertically. Thanks to the additional cavity 14 made in a cavity 10, by simply pressing on one side of the tool 12, the latter exits the cavity 10 on the side opposite to the additional cavity 14 and a user can thus easily grasp this tool.

As mentioned above, the storage module of Figure 3 further comprises the stiffener 4. The objective of the latter is to stiffen the foam block 2 containing tools 12 to facilitate handling. This stiffener 4 will preferably be very light so as to add a very low weight to the assembly consisting of the foam block 2 and tools 12 it contains.

In a preferred embodiment, the stiffener 4 is made from a cellular plastic plate folded and formed so as to be able to contain the foam block 2. By way of non-limiting example, the thickness of the plate used to make the stiffener 4 is for example 4 mm. In Figure 3, it is noted that the stiffener 4 has a bottom 16 of rectangular shape. On two opposite edges of the bottom 16 extend perpendicularly to the bottom 16, side edges 18. These side edges 18 extend over the entire width of the bottom 16. Each side edge 18 is folded at its free end so as to form a fold 20 extending parallel to the bottom 16 towards the opposite side edge 18. A third side of the bottom 16 carries a heel 22 which extends perpendicularly to the bottom 16. In this embodiment, the foam block 2 can be easily introduced and removed from the stiffener 4 by being guided along the lateral edges 18 and 20. The heel 22 then serves as a stop for the foam block 2. The latter can then be easily and quickly slid into or removed from the stiffener 4 which forms a sheath for the foam block 2. In the given numerical example previously for the foam blocks 2, the distance between the two side edges 18 is here 460 mm while the distance between the bottom 16 and a fold 20 is 60 mm. These folds 20 then overhang a block of foam 2 introduced into the stiffener 4 on a strip of width for example between 10 and 15 mm. The heel 22 has a height of between 20 and 30 mm and extends over only a portion of the length of the bottom 16, for example over 400 mm. As illustrated in FIG. 4, a block of foam 2 may also be introduced into a bag 24. The latter comprises a bottom 26 and a cover 28. The bottom 26 is dimensioned to receive without play a block of foam 2. The face of the cover 28 oriented towards the bottom 26 is lined with a layer of foam, for example with a thickness of 5 mm. Thus, when the lid 28 is closed again, the layer of foam in the lid provides a vertical wedging of the tools 12 housed in the cavities 10 of the foam block 2. FIGS. 6A to 6D show a box 30 inside which are arranged four storage modules. Such a box may be called a level 1 box because it contains a quantity of tools corresponding to level 1 described above. The body 30 is made of synthetic material. It is mounted on two wheels 32 and comprises on the one hand carrying handles 34 and on the other hand a retractable handle 36. This box 30 has a lid 28 'also lined inside a layer of foam. The retractable handle 36 is on the opposite side to the lid 28 '. This retractable handle 36 is mounted so that on the body 30 that when the body rests on the wheels 32, a user can comfortably pull the box 30 by pulling by the retractable handle 36. Such a box 30 is well suited to transport by airplane and weight constraints related to the transport of objects in accompanied luggage are respected. Inside the body 30 are wedges 38 very compact foam. These are glued on the inner walls of the box and extend perpendicular to the opening of the box. The shims 38 define inside the box internal dimensions corresponding to the values allowing the lateral setting of a set formed of a block of foam 2 and a stiffener 4. The box 30 shown in Figures 6A to 6D allows to stack four storage modules formed of a foam block 2 and a stiffener 4 one above the other. Thanks to the folds 20 of the stiffeners 4, the storage modules can be stacked on top of one another without an upper module coming to press the tools 12 and the foam block 2 of a lower module. Once the lid 28 'closed, the foam lining the bottom bears against the top of the storage module at the top of the stack and, by domino effect, vertically wedge all the modules arranged in the box 30. Another type of container proposed in the present invention is shown in Figure 7. This container is in the form of a mobile workshop 40 for use in level 2 interventions. This mobile workshop 40 has a chassis 42 , for example made of aluminum, and dressed with side walls, for example made using Teflon plates. This mobile workshop 40 is preferably made in the standardized format of European pallets and thus measures approximately 120 cm wide and 80 cm deep. It also has wheels 32 'and its height, including wheels, is about 130 cm. Inside the mobile workshop 40 are two juxtaposed furniture, each piece of furniture having eight sliding trays 44. Each of these sliding trays 44 can receive a bag 24 inside which is a block of foam 2 filled with 12. These sliding trays 44 can advance out of the furniture so as to allow the opening of the lid 28 of the bag 24 and thus access to the tools 12 in said bag 24. Thus access to the tools 12 without having to completely remove the bag 24 out of the mobile workshop 40. Of course, it is also possible to remove the bag from the furniture and take it closer to the task at hand. In the lower part of the mobile workshop 40, under the frame 46, there are two spacers, one along each small side, to ensure the lifting of the mobile workshop 40 by a forklift. The wheels 32 'are here four in number. They are preferably adjustable, braked and removable for transport. The upper part of the mobile workshop 40 comprises a work surface 46 on which can be fixed a vice 48. Inserts made in the work plane 46 allow for example the attachment of the vice 48. Side handles 50 are also provided on the worktop 46 in the embodiment shown in Figure 7. It can also provide tappings in the work plane 46 to slip there lifting rings. The vice 48 can be stowed, during transport, in a compartment (not shown) located at the rear of the mobile workshop 40 and accessible via two side doors located on each side of the mobile workshop 40 This compartment can also be used to store during transport various environmental elements such as air hoses or lighting. Note also in Figure 7 a plate 52. In this Figure 7, the plate 52 is mounted in slides (not shown) disposed at the rear of the mobile workshop 40. Pins (not shown) allow the maintenance to a given height of the plate 52. In the position shown, this plate 52 serves for example to display documents necessary for the construction site, for example work cards and / or plans. This plate 52, once removed from its wings, is intended to come close the front face of the mobile workshop 40. A key lock can be provided. For a Level 3 intervention, a larger container may be provided. Such a container is preferably suitable for transport by air freight. There is proposed here a container whose dimensions correspond to a standardized container type LD3. The general external dimensions of such a container are 156 cm x 153 cm x 163 cm. Such a container is generally made of aluminum plates mounted on a frame itself of aluminum. The doors, depending on the models and the level of protection of the desired freight, may be impregnated canvas or aluminum panels hinged in their middle to facilitate opening. It is proposed here to arrange fixed furniture with sliding drawers in the container, on the same principle as the mobile workshop 40 described above. The furniture is then dimensioned to receive sets formed of a foam block 2 filled with tools 12 in a bag 24. There is also provided sliding trays in the furniture to open the lids of the bags and therefore d access to the contents of these, without having to remove the suitcase entirely out of the furniture. Of course, it is also possible to remove the bag from the furniture and bring it closer to the task at hand. In addition, an additional piece of furniture corresponding to a mobile workshop 40 described above takes place in the type of container LD3. For transport, the mobile workshop 40 is mounted in the container via a retractable steel ramp. It is wedged by the access ramp once it folded on the inside of the container and its wheel brakes are blocked. It is also conceivable to house in the type LD3 container, as described above, two workshop maids (not shown) each corresponding, in terms of capacity, to a half mobile workshop. All of this furniture is lockable and the entire container is secured by padlocks. Since a container of the type LD3 is known to those skilled in the art, it seemed unnecessary here to represent such a container in the figures. Various arrangements of the interior of the container can be envisaged. In the various embodiments described above, it is noted that a base element, the foam block 2 furnished with tools 12, is disposed inside a container. The latter is firstly adapted in size to the number of tools (foam blocks) necessary for the intervention to be performed and secondly to any constraints related to its transport. Depending on the criticality and therefore the delay of the intervention, two scenarios can be envisaged. In the case of an urgent intervention, the transport of tools is done by accompanied luggage. The weight constraint is here a very strong constraint. The container is chosen so that the total weight of the kit-containing tool-storage unit assembly is less than the upper limit per baggage set by the airline borrowed by the response team technicians. In such a case, the container is most often a box 30 described above as a level 1 container. Such a box is easy to handle, rigid, robust and its weight is optimized.

In the case of a non-emergency intervention, the transport of tools can be carried out by means of conventional road or air freight and the weight constraint is less important here. It is then technically possible to carry as many tools as you want but the greater the weight transported, the higher the costs of transporting the tooling. It is therefore appropriate here to optimize the weight of the carried tooling and its container. The latter is then chosen essentially according to the quantity of tools required. The container used here can be the same as the one identified above for an urgent intervention if the number of tools to take away is small. If the number of tools (storage modules) to be shipped is greater, the container chosen may be for example a mobile workshop 40 or, in the case of a more substantial intervention, a container type 3 level, for example a container type LD3. Of course, other container solutions are usable depending on the constraints related to transport. For the management of the tool magazine, the present invention proposes the use of a dedicated computer system as well as the identification of each tool by a unique number, said number being converted into a barcode affixed to the tool. In the same way, each tool consumer (site, individual) is identified through a unique number and an associated barcode. These barcodes are read by an optical gun with barcode reading.

The present invention proposes, in an original way, to assign to each foam block 2 an identifier. A first step is then to create a module identifier as a tool consumer, exactly as a site identifier would be created. This identifier is then declared type "GTB" (abbreviation of the English expression "Generic Tool-Box or Generic Toolbox.) In a second step, all the tools contained physically in the module are saved in the computer system. as on this module, just as if it were a classic site, by reading the corresponding barcodes.In a third step, we create an article (tool) in the computer database that presents the same code as the module identifier created in the first step This article will also be declared as "GTB" In a fourth step, the "GTB" article is administratively received in the store's stock. output, the barcode corresponding to the consumer (a building site or an individual) is read, then the barcodes corresponding to the modules concerned are read as well.The fact that each module is identified as being of the "GTB" type causes the automatic decoding by the computer system of the contents of this module and the recording of the code of each of the articles contained in this module as being outputted to the consumer. Once these movements have been recorded, the production of transport documents is done automatically by assigning articles delivered to the consumer to a shipping number: a packing list specifying each of the articles contained in the module can thus be produced. This system thus makes it possible, by a single reading of barcodes, to record several movements of tools, the number of recorded movements corresponding to the number of tools contained in the storage module. The transport documents, including the packing list, can then be generated with the same precision as if each tool had been saved individually. Compared to the state of the art prior to the present invention, for a module containing n tools, the gain in number of operations performed is then 30 n-1. If we imagine an average number of tools per module of 50, the modular recording system proposed here can save 49 barcode reading operations per saved storage module. Experience shows here that for the preparation of tools required for a construction site, the preparation of transport documents goes from several hours to only a few minutes.

It is the same for the organization of the transport for the return of tools. In the case of bulk boxes, there are only two solutions: replace the same tools in the same containers to perfectly stick to the original documents or rewrite the documents (which can cause problems in case of temporary export ). Thus, in any case, this operation is difficult to achieve on site and costly in time. This problem is totally solved by the approach according to the invention since in this case, the content and documents are the same on the outward and return journey. With a system as described herein, two types of operation are to be distinguished depending on the type of intervention and thus also on the means of transport chosen. In the case of an emergency intervention, as already mentioned above, it is preferable, but not exclusively, to use a box-type box 30 described above. After the selection of the storage modules to take place in this box, the modules being chosen according to the type of tasks to be performed, the selected modules are recorded in the computer system by reading their bar codes, which allows to produce very quickly the transport documents. In this case, they are modules comprising a foam block and a stiffener. For a team of two to 20 people, a full level 1 tool kit requires the handling of eight modules that are recorded by reading eight barcodes. The rest of the operations are automatic. For example, the transport list is edited automatically. In comparison with the state of the prior art, the recording of the same number of tools, when tool-by-tool, would amount to handling hundreds of articles and reading hundreds of barcodes. Compared to the prior art, there is therefore a time saving quite significant. Note also that in the prior art, the tools are arranged loose in a box while here these tools are arranged by category in storage modules. This makes it possible to work more efficiently on the site and to more easily check that no tool has been left on the aircraft. In the case of a standard intervention, that is to say non-urgent, the approach is exactly the same. Here, the foam blocks are rather arranged in suitcases and not in stiffeners and the container is of a different type. Compared to an urgent intervention, the time saving is even more important since the number of tools is generally higher. Storing tools in the storage modules also helps to be more efficient on the job site. Of course, the present invention is not limited to the various embodiments described above by way of non-limiting examples. It also relates to the embodiments within the reach of those skilled in the art, not mentioned above, and in the context of the claims below. For example, the foam blocks are not necessarily all the same thickness. To be able to house more tools in a box for example, it would be possible for tools of small thickness (flat wrenches, screwdrivers, sockets, ...) blocks of foam of lesser thickness, for example of a thickness. corresponding to half that of standard blocks. Other dimensions (length and width) could be retained. Other modifications on the foam blocks can be envisaged (monocolore or tricolor or ...). The containers described are given for illustrative and not limiting. Other embodiments may be envisaged. For example for crates, we can consider crates containing not four storage modules but three or five (or another number).

Tooling has been classified into four subassemblies. It is possible to have a larger number of subsets or to define in the subsets indicated above other subsets. For example, in the subset concerning tools for an intervention in the electrical field, a subset of specific tools may be provided when the intervention is to be performed on an aircraft equipped with aluminum wiring. Especially for the tools of the subset concerning the tasks on the structure of the aircraft, one could provide a subset that could be called "cutting tools". Here we find tools of the drill type, reamer, strawberry, ....
