Definitions
- the present invention relates to the establishment of a new technical device and to the provision of new workshops thus produced.
- the invention relates more particularly to the equipment of an enclosed room in which the maintenance operations and the stripping and painting operations are carried out.
- the invention relates specifically to the installation of a room, in particular a hangar allowing stripping operations and painting operations for land, sea or air vehicles, by means of a stripping product by a process of dry spraying using one or more spray nozzles located in one or more remotely controlled pickling stations.
- the invention relates in particular to an installation intended to ensure the command and control of pickling and / or painting operations using the spraying of a pickling product intended for pickling aircraft cells, by means of nozzles arranged around the entire periphery of the vehicle immobilized in the installation, as well as the pickling and / or painting stations and the equipment used.
- the minimum installation load can be 16 planes at departure, it can be increased to 50 planes which are pickled over 313 working days.
- the stripping operations can be carried out manually by operators or by remote controlled devices mastering the conditions and parameters of the stripping and / or painting process.
- the pickling is carried out by projection of dry media by means of an optimized projection nozzle, manipulated by an operator, and supplied by a media / compressed air mixture thanks to a generator.
- the air / media mixture, brought to the operator's nozzle, is created at the level of a generator consisting of a pressure pot containing a certain amount of abrasive at the operating pressure and of a specific distributor, controlled at distance, letting the desired amount of media through the compressed air flow.
- the flexible hose ensures the transport of the mixture with minimum loss and wear
- each projection nozzle has its own generator, distributor, and supply hose
- the projection conditions can be adapted for each nozzle as a function of the nature of the material to be etched. These etching conditions are imposed by the supervisor.
- Pickling is carried out by projection using an optimized compressed air projection nozzle, handled by an operator equipped with protective equipment.
- the pressure of the projection air can vary from 1.5 to 3.5 bars with a flow rate of 200 to 350 Nm 3 / h, and the media flow rate from 1 to 3 kg / min.
- the inlet hose for the abrasive air mixture has an outside diameter of approximately 50 mm.
- nacelles or docks arranged around the machine. These nacelles or docks are mobile, and can possibly be moved during the stripping phase.
- the media is projected onto the areas to be stripped, and a mixture of reusable media, used media and paint and / or pickled waste, mainly falls on the floor of the workshop. Retention zones are therefore necessary
- the projection system used is based on the classic operation of pressure type compressed air projection machines
- the air / abrasive mixture brought to the operator's nozzle, is created at the level of a generator consisting of a pressure pot containing a certain quantity of abrasive at the operating pressure and of a distributor letting through the desired quantity. of media in the compressed air flow Between this generator and the nozzle, the flexible hose ensures the transport of the mixture with minimum loss and wear
- each projection nozzle has its generator and its supply pipe
- the abrasive mixture falling on the ground must be recovered to be then reprocessed
- the technical and economic optimization of the process requires recovering the media and the reusable part of the mixture must be separated from the waste Given the defined particle size of the media, the recovery rate is around 80%
- the recovered media and the new media are used to power the generators
- the generators supplying the nozzles are installed in a fixed manner, they must be located at a certain distance from the equipment to be treated, the closest being along the walls of the workshop. This leads to the presence of as many supply pipes for the nozzles on the workshop floor In addition to the pressure losses and wear related to the minimum lengths, the discomfort caused by the presence of these pipes are significant cumbersome to implement (storage, cleaning and installation), hindering the traffic, hardship for operators (weight, response time, etc.) There is no need to have generators with very large quantities of media. About 50 liters are enough to allow continuous projection, without interruption for 20 minutes, a few minutes.
- the pickling medium or product used in the pickling device according to the invention is one of those described in French patent 2,761,365 in the name of the Interprofessional Syndicate Biodecap.
- a vegetable polymer derived from wheat flour, crosslinked by a chemical agent is used for this purpose, having abrasive properties, in particular allowing the stripping of aeronautical paint systems, while preserving the substrate from any damage.
- the paint system used for airplanes, train powerplants or for boats consists of a system formed by a layer of primer and various functional layers (anti-erosion, anti-corrosion).
- the primer layer is intended to ensure cohesion between the substrate and the functional layers.
- the location of the technical platform according to the invention is notably formed by a mobile pickling unit, controlled and operated remotely comprising:
- the frame of a hangar (11) will be noted inside of which an airplane has been represented during pickling and reconditioning operations.
- the establishment successively includes:
- the lines (10) symbolize the computer and energy connections between the connection blocks and the pickling stations. These are flexible connections connecting a fixed block and a mobile station whose location is determined by the morphology and dimensions of the machine to be reprocessed.
- the media After stripping the machine, the media will be recovered by suction and will be rid of other waste by a sieving system. In particular, care is taken to maintain a satisfactory particle size which will allow the abrasive material to be recycled.
- the generators (8) supplying the nozzles (12) are fixedly installed, they are located at a certain distance from the machines to be treated, the closest being placed along the partitions of the workshop. This results in the presence of supply pipes for the nozzles equal in number to that of the generators on the floor of the hangar.
- the soiled media falling to the ground is recovered and then recycled. By sieving, up to 80% of the media used can be recovered.
- the recovered media is mixed with new media to be used for a new operation.
- the stock of media does not need to be large, approximately 50 liters are sufficient to allow continuous projection without interruption for 20 minutes. It is then necessary to re-supply the pressure pot to the compressor from a storage store. A few minutes are sufficient for this operation.
- each generator nozzle is associated with a generator assembly mounted on an independent carriage.
- This carriage shown in Figure 2 is easily movable on the ground and is movable in height. It can thus be positioned as best as possible according to the areas to be treated and the dimensions of the machines to be stripped.
- the supply to the carriage (23) of the energy sources must be adapted to the needs.
- the stripping carriage (23) is shown in Figure 2. It is movable by an operator. It comprises :
- a distributor assembly (18) allowing remote regulation of the media flow, in particular by means of a jack (22) 3.
- an electro-pneumatic automaton which allows the local processing of the operation of the pickling unit, operation of this unit itself imposed by the instructions of the supervisor:
- Figure 2 shows the mobile carriage (23) in elevation ( Figure 2A) or above ( Figure 2B).
- the carriage is made mobile by a human operator. It is obvious that the movements could be remotely controlled and / or carried out by an electric motor.
- FIG. 2A shows a weighing system (16) of the generator (17) in side view (the same weighing system (28, 28 ', 28 ") in top view is shown in Figure 2B).
- distribution of the abrasive (18) is arranged at the base and is remotely controlled by means of a mechanical or pneumatic sealing device (22).
- These elements allow the supervisor, by l 'Intermediate of the PLC, to control the media flow, whatever its particle size.
- FIG. 2B shows the carriage (23) seen from above, on which are located the electrical control cabinet (26), the accesses for maintenance (24) (24 ').
- the supply support in the flexible receptacle (13) has a capacity of approximately 500 liters. This volume can be easily changed from 200 to 2,000 liters.
- the media supply support in the flexible receptacle (13) has a capacity adapted to the needs.
- the installation according to the invention therefore comprises a hangar for receiving machines, the dimensions of which can vary from 50 to 150 m long by 10 to 25 m wide.
- the mobile carts used for the projection of the media are 1,500 to 2,000 cm in length, a height above the ground between 300 and 500 cm, a receptacle flexible cylindrical-conical shape from 900 to 1,200 cm high with a diameter of 800 to 1,000 cm.
- the height of the gantry supporting the distribution system varies from 1,100 to 1,500 cm.
- the total height of the mobile cart varies from 2,500 to 3,000 cm.
- the overall width of the cart varies from 1,800 to 2,200 cm.
- the abrasive flow is between 0.5 and 6 kg / min at a pressure between 1 and 6 bars.
