Definitions

  • the invention relates to an installation for spraying coating product such as paint, of the type in which the object to be coated, carried by a conveyor, passes opposite the area of activity of a robot manipulator called hereinafter automaton carrying a projector diffusing the coating product in the form of fine particles.
  • the invention relates more particularly to a new arrangement making it possible both to solve the problem of color changes when the objects which follow one another in front of the automaton must be painted in different colors as well as the problem of the necessary galvanic isolation between the means for distributing coating products and the means of spraying when the paint used has a low resistivity (water-based paint) and when said spraying means incorporate a high-voltage source for carrying out an electrostatic spraying .
  • a paint spraying installation in a production unit as large as an automobile manufacturing plant, for example, generally has several very long closed-loop paint distribution circuits (these circuits can cross a whole section from the factory) which establish the link between large paint tanks and the different projection booths. It is therefore necessary to provide such a circuit by color and another circuit of the same kind for the solvent or cleaning product. For obvious safety reasons, these circuits are connected to earth.
  • the objects to be painted in this case automobile bodies in the example envisaged, are carried by conveyor means passing through the booth in which there is at least one PLC carrying a paint projector and capable of operating in a certain "activity area" inside the cabin.
  • PLCs is commonly IJ sed having up to six or seven degrees of freedom or axes, in order to direct at will the projector and to enter certain enfractuosity of the object to be painted. For simple forms, one can be satisfied with an automaton comprising only three or four degrees of freedom.
  • the projector can be electrostatic at high speed, pneumatic spraying or hydrostatic.
  • the automaton most often comprises an arm of several segments articulated with respect to each other, this arm possibly being carried by a movable frame along the conveying means.
  • One of the usual problems to solve in this type of installation is that of the color change between two consecutive objects. Indeed, in the automobile industry, in particular, there is no question of painting the bodies in series, according to the color. The most frequent case, on the contrary, is that where the color must practically be changed after each bodywork. This implies being able to implement rinsing and drying cycles of extremely rapid spraying means. For example, a color change can take place every minute or so and the time allowed to carry out all the operations necessary for the color change is of the order of ten seconds.
  • all the coating product distribution circuits are connected, as well as a compressed air circuit and a cleaning product circuit, through controlled isolation valves, to a collector, one branch of which common output is connected to the projector.
  • the collector can be placed fairly close to the projector, i.e. on one of the last articulated segments of the automaton, each coating product being supplied by a flexible conduit.
  • this solution is no longer practical. ble and the collector must then be placed at a fixed station, its outlet being connected by a single flexible duct to the projector.
  • the automata are subject to large displacements parallel to the largest dimension of the objects to be coated, for example five or six meters.
  • the collector is very far away, for example ten meters, from the projector, which considerably increases the volumes of ducts to be cleaned, therefore the time for the color change sequences.
  • We are often forced to double the supply circuits (collectors, valves, conduits) to use a projected part while the other part undergoes a cleaning and color change cycle.
  • the quantities of coating product and cleaning product lost are large, of the order of several hundred cubic centimeters.
  • the pressure regulator and the purge valve being in the immediate vicinity of the projector, in an area which may contain a flammable gas mixture and which can be brought to high-voltage when the projector is of the electrostatic type, the control of this device is usually done by compressed air, which requires additional pneumatic lines.
  • the dielectric strength of these conduits must be sufficient, taking into account the high voltage applied.
  • the quantity of product that they contain represents a relatively large electrical capacity capable of storing energy well above the tolerated limits.
  • French Patent No. 2,572,662 suggests filling an intermediate reservoir with the amount of paint just necessary for each application.
  • This intermediate tank is stationary, so that each color change requires cleaning not only the tank, but also all the conduits connected to it.
  • the re-establishment of the isolation after filling is done by emptying and drying a sufficient portion of conduit, upstream of the intermediate tank. This operation requires a probihitive time each time the color changes.
  • the invention proposes to solve the problems of color change by considerably simplifying the equipment located between the distribution circuits and the projector, whatever the type of coating product used.
  • the invention also proposes to reduce the time necessary to carry out a color change, even when the number of different colors is large and the automaton responsible for moving the projector has to move great distances due to the size of the objects to be coated.
  • the invention further proposes to solve in a particularly simple manner, the problem of insulation between the electrostatic projector and the distribution circuits of coating products, brought to the earth's potential.
  • the invention mainly relates to an installation for spraying coating products comprising at least one automatic device of the multi-axis type, carrying a product projector, movable opposite a conveyor carrying objects to be coated, characterized in that different coating product distribution circuits, are provided with respective first, similar connection means, grouped together at a fixed station in an activity area of said automaton, in that said automaton carries a coating product reservoir, at least during each projection phase, connected to supply said projector and in that this reservoir communicates with or is provided with first complementary connection means capable of cooperating with said first connection means of any one of the coating product distribution circuits.
  • the coating product reservoir can be permanently mounted at the end of the arm of the controller.
  • this arm it suffices for this arm to be able to orient itself, at each color change phase, towards the first aforementioned connection means as well as towards other means of connection of a cleaning product distribution circuit, for clean the tank and fill it with a coating product of another color.
  • an intermediate solution may consist in using only two removable reservoirs, one of the reservoirs being carried by the arm of the automaton while the other is connected to the distribution circuits for coating product and cleaning to undergo a color change cycle.
  • the quantity of coating product introduced into the tank for each spraying phase does not need to be adjusted according to the dimensions of the object to be painted.
  • the dimensions of the tank only depend on the ability of the machine to support and quickly move a certain mass of coating product. If the automaton cannot support a reservoir of sufficient dimensions to contain all the quantity of coating product necessary to completely paint the object, it is perfectly possible to consider recharging this reservoir one or more times during the idle times of the projection phase. If, on the other hand, the capacity of the reservoir makes it possible to accommodate more coating product than necessary for a spraying phase, the excess quantity is reinjected into the corresponding distribution circuit, at the start of the color change cycle.
  • FIGS. 1 to 3 we have - schematically a first embodiment of the invention, in a paint booth 11 crossed by conveyor means 12 circulating objects 13 to be painted (in this case here automobile bodies) near an automaton 14.
  • This automaton is of the multi-axis type, known per se; it mainly consists of a chassis 15 movable on a guide 16 extending over a certain distance along the conveyor means and of an arm 18 carried by the chassis, composed of several segments 18a, 18b, 18c articulated one on the other compared to others.
  • the chassis 15 itself comprises two parts 15a, 15b connected by an articulation with a vertical axis, allowing it to pivot on itself, as seen in the comparison of FIGS. 1 and 2.
  • We define as "zone of activity "of said automaton all the space of the cabin that can be reached by the automaton and more particularly by the last segment 18c of its arm.
  • the segment 18c carries the means for spraying the coating product, in this case a projector 20, supplied with compressed air by a flexible duct 21 and according to the invention, a reservoir for coating product 22.
  • the automaton can include a high-voltage generator 24 connected to the projection nozzle or to the bowl in the case of a high speed rota sprayer tion.
  • the high-voltage generator 24 is adjustable at will, that is to say in particular that its output voltage can be reduced to zero at any desired time and restored almost instantaneously under the action of control means. very classic. This possibility of adjusting the high-voltage, although banal in itself, is of particular importance in the context of the invention, since the projector is, at each filling and / or cleaning sequence, connected to the distribution network of grounded product.
  • the reservoir 22 is permanently mounted on the last segment of the automaton and communicates with the projector 20. If the reservoir is too large to be able to be mounted on the last segment, it can be mounted on the penultimate and connected by a flexible conduit to the projector.
  • conduits forming part of different distribution circuits pass through the cabin 11; they are for example fixed along a wall 26 thereof.
  • paint distribution circuits P1, P2 and P3 these are paints of different colors
  • cleaning product distribution circuit N there is also provided a compressed air supply circuit A to which the conduit 21 is connected, by means of a controlled valve 25.
  • the circuits P1, P2 and P3 are provided with first connection means 28a, respectively, similar, grouped in the activity area of the automaton defined above, that is to say in the vicinity of the wall 26.
  • Each of these first means of connection of any of the circuits P1, P2, P3 is capable of cooperating with first complementary connection means 29a carried by the reservoir 22.
  • said first connection means of each circuit P1, P2 or P3 are simply constituted, respectively, by a single connector element of the "racco" type rd rapid self-closing ball "well known in the art while the first complementary connection means 29a are only constituted by another connector element, of complementary structure, capable of being plugged in tightly to one of the elements of the connector of circuits P1. P2 or P3.
  • the cleaning product distribution circuit N and the waste evacuation circuit D respectively comprise connection means 28b, 28c, to the reservoir 22, in this case identical to said first connection means of circuits P1 , P2 or P3 since they consist of the same connector elements. All the connection means 28a, 28b, 28c are grouped very close to one another in said zone of activity of the automaton.
  • a waste recovery receptacle 30 is also located in the activity zone, not far from the connection means 28a, 28b and 28c. This receptacle is designed to receive any product (paint or cleaning product) rejected as a jet by the projector 20.
  • the compressed air line 21 can communicate directly with the reservoir 22 if the automaton is programmed so as never to place the pressurization air supply at a level below the paint outlet, so as to avoid air being directly discharged from the projector when it is facing an object to be painted.
  • a control system, known per se, of the quantity of paint sprayed makes it possible to never completely empty the tank during spraying. It is also possible to use another type of reservoir comprising a piston or a deformable member, arranged to divide the internal space of the reservoir into two chambers, one of the chambers receiving the product and the other being intended to receive air. under pressure.
  • first complementary connection means 29a communicate with the chamber receiving the product and that the conduit 21 communicates with the other chamber, in order to push back the piston or the membrane as the evacuation of the product by the projector 20 or by the first complementary connection means 29a.
  • the controller 15 pivots on itself to approach the reservoir 22 of the location of the cabin where the various connection means described above are located. If it is necessary to change the color of the paint, for example switching from the paint dispensed by P1 to the paint dispensed by P2, the machine first connects the reservoir to the circuit P1 so as to reinject the excess of paint or at least most of this excess by controlling the amount repelled to avoid injecting air into this circuit.
  • the automaton puts the reservoir 22 in communication with the cleaning product distribution circuit N, the circuit 21, by virtue of the three-way valve 25 being vented to allow the tank to be filled.
  • the automaton connects the tank, always by the same connection means, to the waste evacuation circuit D and the valve 25 is again connected to evacuate the cleaning product in this circuit.
  • the two previous operations are possibly repeated several times, if necessary, until the tank is clean.
  • the machine directs the projector 20 towards the receptacle 30 and compressed air is again injected to drain a small part of the cleaning product through the projector, so as to clean it.
  • the automatic device connects the reservoir 22 to the distribution circuit P2 while the circuit 21, thanks to the valve 25, is again vented to allow the reservoir to be filled with the new paint.
  • the automaton brings the projector 20 back to the receptacle 30 to project a small amount of product therein and thus eliminate the last traces of cleaning product. From this moment, the color change cycle is completed and the automaton can again pivot on itself to paint a new body.
  • the high voltage is brought to zero before the start of the color change cycle and is not re-established until the end of the cycle. It is clear that during the entire projection period, the high-voltage is perfectly isolated from the various distribution circuits connected to the ground since there is no product conduit between them.
  • FIGs 4 and 4 where the similar elements have the same alphanumeric references, illustrate a variant in which the color change cycle can be very significantly shortened, since it requires no cleaning.
  • the installation is provided with as many coating product reservoirs 22 1 , 22z. 22 3 ... as distribution circuits P1, P2, P3 ...
  • These tanks are therefore not permanently dismantled on the automaton but are not connected to it by second connection means (not shown) carried by the automaton capable of cooperating with second complementary connection means 34a, 34b provided on each. tank.
  • connection means are composed from the same connector elements as those used in the first embodiment described.
  • the second connection means provided on the automaton consist of two connector elements spaced by a predetermined distance while the second complementary connection means 34a, 34b also consist of two corresponding connector elements spaced by the same distance for adapt to the elements carried by the automaton.

The latter are spaced by a predetermined distance on either side of a restriction 35 connected in series in the corresponding circuit P1, P2 or P3, this circuit being, as usual, of the continuous circulation type in closed loop .
  • said first complementary connection means provided on each tank comprise two other connector elements 29a, 29a 2 spaced apart by the same distance, along said tank.
  • the circuits P1, P2 and P3 have a variation in height on either side of the restriction 35.
  • the arrangement is such that the two connector elements 28a l , 28a 2 are arranged at different levels , the connector element 28ai placed at the highest level being downstream of the other connector element, with respect to the direction of circulation of the coating product in the corresponding distribution circuit.
