    [0001] The present invention relates to a test or filling adapter for transferring one or more fluids from a test or filling machine to a fluid circuit. It finds particular application during the transfer of fluids such as coolant, brake fluid, air conditioning fluid, for the corresponding circuit of a vehicle, during the test or filling of such a circuit, for example on an automotive assembly line, or in the energy sector for the filling of heat pumps, or electric radiators fluid.
    [0002] The fluid or fluids can be mixtures of fluids, as in the case of a heat-transfer mixture of the water / glycol type, or of a mixture obtained by successive injection of a first fluid such as a polyalkylene glycol type oil ( PAG) and a second fluid such as a refrigerant such as tetrafluoroethane (R134A). On the car chains, it is always necessary to be able to have fluids to fill the various circuits of the vehicles being assembled on the chain of production. The adapter is a specific tool that connects to the fluidic circuit in a sealed way, in most cases, via a temporary connection, automatic or manual, integrating hydraulic and pneumatic elements to ensure a fluid connection between the unit of filling and the circuit to fill. The operator uses the adapter when filling or testing each circuit of the vehicle: it must be robust, lightweight, ergonomic ... despite this, it remains a vulnerable tool and it must be repairable or changed very quickly without stopping the production line and without pollution of the work area during its repair or change. Currently, the adapters on the assembly lines are integrally connected to a long sleeve connecting the adapter manipulated by the operator to the test machine or filling. In a variant, there is not a sheath per se but a bundle of fluid conduits and electric cables held together. To simplify the description of the invention, we will describe later a configuration with a sheath, knowing that by sheath is meant as well a sheath forming a sheath inside which can run cables and ducts, a beam comprising cables and / or conduits held together. The sheath is connected to the reservoir of the test or filling machine by a system of fluid connectors more or less fast to disconnect. In addition, this sheath is generally taken up by tensor systems to avoid rubbing the ground, 3031160 2 or anti-tearing systems which detect a too strong tension of the sheath between the vehicle and the test or filling machine. These systems related to the sheath are long to disconnect when it is necessary to disassemble the adapter. In addition, they are security elements that require checking their operation before restarting the installation. The object of the invention is therefore to overcome these problems in particular. It relates to a rapid connection system, lightweight and waterproof which is integrated in the adapter and ensures the connection and insulation to the sheath. According to the invention, the adapter comprises a part integral with the sheath (connecting block) making it possible to connect or isolate said sheath with the rest of the adapter. The sheath is not an element subject to the same constraints as the adapter, it wears little and can be mechanically reinforced, it is not necessary to replace it frequently. According to the invention, only the adapter is disassembled, without the sheath, when necessary, instead of a bulky and heavy system comprising the sheath and its connecting device to the test or filling machine. Thus, the invention has a quick and secure connection system ensuring the seal so as not to contaminate the working area of the operator. Indeed, fluids such as motor oil can quickly make a slippery working area and therefore dangerous for the operator working in said area.
    [0003] The new adapter according to the invention is composed of four main subassemblies: a bonding block connected to the sheath integrating part of the rapid connection system and the sealing of the fluid lines to avoid pollution of the zone of The body of the adapter which can include including a handle of manipulation of the tool by the operator and the complementary part of the quick link system. The body of the adapter can be bent or straight depending on the access to the fluid circuit to be tested or filled. It can also incorporate a slip-resistant and flexible grip on the surface used as a handle to improve the gripping of the tool by the operator. This body can also integrate elements such as controlled valves or sensors dedicated to the same process of testing or filling. These valves can be controlled electrically or pneumatically. An operator interface allowing in particular starting, stopping operating cycles and additional functions (cycle state, machine 3031160 3 operational or faulty ...) allowing the operator to avoid unnecessary trips back and forth To the control panel of the test or fill machine, a lock block is matched to the geometry of the connector present on the fluid circuit to be tested or filled. According to the invention, the adapter is a tool for testing or filling a fluid of a fluid circuit, said adapter being connected to said fluid circuit and being connected by a sheath or a beam to a test machine or fluid supply filling, the adapter and the sheath comprising conduits for the fluids and conduits 10 for the pneumatic control of adapter members and an electrical harness connecting the control / control interface of the adapter to the machine. The adapter comprises two parts, the part providing a connection between the sheath or a bundle and the part that is connected to the fluidic circuit. Said connection comprises a set of connections ensuring the continuity in operation of the conduits and the separation without prior purging. during the maintenance phases, the part also comprises a means whose control ensures simultaneously the mechanical maintenance of the connection and the fluidic continuity of the ducts, or the breaking of the connection and the simultaneous isolation of at least one duct .
    [0004] Thus, the adapter according to the invention makes it possible to quickly change the body / interface / connection block assembly. This change can be used for the purpose of faster maintenance. It can also be used in the case of change of production (change of connection on the fluidic circuit). Indeed, the modularity of this adapter allows, for example, to quickly change from an angled adapter with a claw lock system to the fluidic circuit, to a straight adapter with another locking system on a different fluidic circuit. The only constraint is that the fluid is the same or compatible, (otherwise, it would be necessary to purge the fluid present in the sheath.) The invention also makes it possible to eliminate the fast connection plates at the sheath / test machine interface. or filling, often expensive, of reduced accessibility and sources of pressure drop (and therefore limitation of flow and production capacity) which are sometimes installed between the sheath and the test or filling machine. The invention comprises a receptacle secured to the part in which a pin secured to the part whose actuation simultaneously ensures the maintenance of the connection and the fluidic continuity of the ducts, or the breaking of the connection, and the simultaneous isolation of at least one duct The geometry of the peg allows a quick quarter-turn assembly via a circular assembly with flattening via a groove. Assembly can be used.
    [0005] The advantage of a quarter-turn system is that it requires a simple tool to be disconnected. The operator is therefore not likely to disconnect inappropriately. The footprint of the pin for operating the quarter-turn system can be simple in shape, for example a straight slot operated by a flat screwdriver, or be of more complex shape, so as to have a dedicated tool for reserving this operation only to maintenance personnel and not to the operator working in this area. According to an exemplary embodiment of the invention, in the assembly system between the body of the adapter and the connecting block with the sheath, the pin comprises two parallel flats located symmetrically on either side of its axis, the receptacle 15 comprising a passage in which is slid the pin at the flats when they are positioned parallel to said passage, said pin then being positioned in a cylindrical reservation of the receptacle and rotated a quarter of a turn to maintain the connection and ensure the fluidic continuity of the ducts. This type of mechanical connection is robust, reliable and waterproof.
    [0006] Opening can be done from the right or / and from the left of the adapter. This system is not sensitive to vibrations, does not allow dirt to pass through and resists traction forces (sheath-adapter connection). Moreover, by placing the insulation close to the on-board hydraulic elements for the process, the residual fluid volume is low and thus avoids emptying all the fluidic connections 25 contained in the sheath. Advantageously, the pin is connected to a conduit and actuates an opening / closing mechanism of said conduit when rotating a quarter turn. The opening / closing mechanism uses, for example, a ball valve. In addition to this system which provides the mechanical connection and the insulation of the conduits 30 for the fluids, the system incorporates a quick disconnection without insulation for the pneumatic control ducts for example. Nevertheless, if the number of total connections is large, the force demanded of the operator for link operations may be significant. In this case, the connections ensuring the continuity in operation of the conduits and the separation of said ducts are distributed in at least two distant points in the direction of the engagement race of the body and the connection block and in that sealing connections are performed successively in the at least two remote points. The effort required to achieve the connection between the body and the link block is therefore divided by the number of remote points. Mechanical guidance (positioning pins, guide pin, etc.) can be added depending on the guide length necessary to improve the ergonomics and overall mechanical strength of the assembly. According to the invention, the adapter may also include an easily replaceable operator interface on the body of the adapter. This operator interface allows the control of the operating cycles and also makes it possible to visualize the number of cycles 10 carried out with the adapter, to check the presence of the locking module ... This interface has a great importance in the management of the technical maintenance of the adapter and in the ease of use of it by the operator. Thus, according to a first aspect, the subject of the invention is an adapter for filling a fluid of a fluidic circuit intended to be connected on the one hand to said fluidic circuit and on the other hand to a filling machine. by a sheath comprising at least one fluid supply duct connected to the filling machine and at least one supply duct for control connected to a power supply source for driving, the adapter comprising at least a fluid transfer duct intended to be connected to the supply duct and at least one control duct 20 of one or more members of the adapter, in particular one or more fluid flow control members, intended to be connected The adapter comprises a first portion adapted to be connected to the duct, and a second portion, distinct from the first portion, adapted to be connected to the fluid circuit. ue, as well as means for assembling the first and second parts. The first and second parts respectively comprise a first and a second set of connections, capable of being connected so as to ensure the fluidic continuity in operation, that is to say the adapter connected to the filling machine, part of the transfer and supply ducts, and secondly pilot and supply ducts for piloting. The first and second sets of connections are also capable of being disconnected so as to ensure, when the The second part is disconnected from the first part, such as during maintenance phases, the fluidic separation on the one hand from the transfer and supply ducts and on the other hand from the control and supply ducts for piloting.

    [0008] Hereinafter, several examples of embodiments of the invention will be described in detail with reference to the figures. The examples of embodiment and implementation of the invention given in the present description relate to the automotive or energy sector but are in no way limiting since the invention can be applied to all sectors requiring filling tests, or filling fluids for transfer, especially in the energy sector for filling heat pumps. According to the prior art, FIG. 1 shows, in an automobile assembly line, a fluid filling machine 2 of a fluid circuit 3. An adapter 1 connected to the filling machine 5 by a sheath 4 connects to the fluidic circuit 3 to be tested or filled. A tensor 25 makes it possible to hold the sheath 4 and an anti-tearing device 26 makes it possible to protect the connection between the sheath 4 and the filling machine 5. Fluidic ducts 6 for the fluid 2, ducts 7 for the pneumatic control, and an electrical harness 8 are in the sheath 4 and connect the adapter 1 to the machine 5.
    [0009] FIG. 2 shows, according to a nonlimiting example of the invention, an adapter 1 comprising: a connection block 9 or first portion 9 connected to the sheath 4, to the conduits 6, 7 and to the electrical harness 8, 5 - A body 10 or second part 10 may be of different shapes to adapt to the need for the filling process, - an operator interface 19 allowing in particular the start and stop of the operating cycles directly from the adapter 1; this interface 19 may comprise complementary functions such as the display of the state of the cycle and the number of cycles; - A locking block 22 or attachment module 22 preferably interchangeable to match the adapter 1 to the tip of the fluid circuit 3. The connection between the connecting block 9 and the body of the adapter 10 is obtained through to assembly means 14, 15 distributed on either side of the connecting block 9 and 15 of the body 10, of which only a portion 15 is visible in FIG. 2. When detaching the connecting block 9 and the body 10 of the adapter 1, as shown in Figure 3, is accessed to the connecting members 12, 28 of the ducts 6 and 7 on the side of the connecting block 9, forming a first set of connections 12, 28 and their pendants 12 ', 28' on the body side 10, forming a second set of connections 12 ', 28'. To facilitate the interlocking of the connection points 12 and 12 ', they are shifted in the direction of the engagement race of the body 10 and the connecting block 9. The compressive force on the seals 30 will be less because these seals 30 placed for example at the connection points 12 and 28 and sealing the connections will be crushed successively and not at the same time. In this embodiment of the invention, an electrical harness 8 is connected to the electrical harness 8 'of the body 10 by its end 29 which comes to manually connect to a connector 21. In another example of implementation, this connection could be designed to be made by the same assembly movement as for the connections 12, 12 'and 28, 28'.
    [0010] In order to bond the connecting block 9 and the body of the adapter 10, the part 15 of the connecting means 14, 15 of the connecting block 9 cooperates with the part 14 of these assembly means 14, 15 of the body 10. In this example the assembly means 14, 15 comprise in particular at least one receptacle or lug 14 integral with the body 10 of the adapter 1.
    [0011] FIG. 4 represents an example of a quick assembly means 14, 15 according to the invention. It is composed of a pin 15, also partly visible in Figures 2 and 3. This pin 15 comprises at least one flat 16, preferably two parallel flats 16 located symmetrically on either side of the axis main piece 15.
    [0012] The receptacle 14 comprising a passage 17 formed in an insertion direction d, opening into a cylindrical reserve 18, in which the pin 15 is slid at the flat or flats 16, when the latter or they are positioned in parallel to the insertion direction d. The pin 15 is thus positioned in the cylindrical reserve 18 of the receptacle 14, and is rotated a quarter of a turn to bring the flats 16 perpendicular to the direction of insertion d, and thus maintains the binding of the body 10 and the connecting block 9, preventing the return passage or flats in the passage 17. Concomitant with the quarter turn assembly, the assembly means 14, 15 can close or open at least one of the duct connections 6, 6 '15 and 7, 7' to ensure the continuity or the fluidic isolation of these duct connections 6, 6 'and 7, 7'.As shown in FIG. 5, according to a variant of FIG. embodiment, two assembly means 14, 15 are put in place on either side of the adapter 1 to facilitate the separation of the body 10 and the connecting block 9. Each pin 15 is connected to a valve-type means 24 placed at the level of the connections 12, 12 'of the conduits 6, 6' and connections 28, 28 'of the products 7, 7 '. These valves 24 may be in particular quarter-turn actuable ball valves. When the operator connects the body 10 and the connecting block 9, the flats 16 penetrate into the grooves or grooves constituting the passages 17 presented above with reference to Figure 4, and are housed in the corresponding cylindrical reserves 18. The connectors 12 and 12 ', and 28 and 28', fit together. The operator then uses a tool, which can be specific, to rotate the pins 15 a quarter of a turn on both sides of the adapter 1. The quarter-turn action blocks the flats 16 in the cylindrical reserves 18 ensuring the connection of the body 10 and the connecting block 9 and opens the valves 24 restoring the fluidic connection between the body 10 and the connecting block 9. A reverse quarter turn allows to release the connection and close the valves 24 ensuring l tightness of the whole.
    [0013] The valves 24 may be electrically operated valves, in which case the action of opening or closing the valves 24 by the pin 15 may be of the electrical interruption type. According to an exemplary embodiment of the invention, the adapter comprises, in addition to the fluidic connections (transfer or control), one or more electrical connections 8 ', 21, 27 for the connection of the onboard operator interface 19 on the adapter 1 visible in particular in Figure 6. This control / control operator interface 19 is placed on the upper part of the body 10 and is an easily interchangeable assembly by means of a mechanical connection 20 and a quick electrical connection 27.
    [0014] This interface 19 can also integrate mechanical guides for ergonomics during the changeover, but also to improve the mechanical adjustment and the tightness with respect to the body 10. Indeed, for some applications with potentially aggressive liquids, it can it is necessary for the electrical interface 19 to be completely sealed with respect to the fast fluid connection system. For this, one can use a waterproof electrical connector (IP67). Indeed, it is necessary to ensure the proper functioning of the interface because it incorporates functions that can be "key" such as push buttons 191 and 192 on / off, a counter 193 with the number of start / stop and a bar graph illustrating this one. The interface can also integrate more sophisticated functions. For example, the presence of the locking block 22 can be detected by the control / control interface 19 via a device 23 for checking the presence of said locking block 22 on the adapter 1. This may have the primary purpose of check the integrity of the system before use. This also makes it possible to trace a disassembly of said block 22 of the adapter 1 and thus to check the maintenance intervals of the adapters 1.
    [0015] This detection can be carried out, for example, by an inductive presence sensor. The interface 19 can integrate a system having its own memory to record this information. Following the analysis of these, it is possible to control at which periodicity were carried out the dismantling. This data can also be sent to an external control system, for example that of the filling machine 5, for example in order to trigger maintenance alarms as a function of the number of cycles performed or the operating time. The adapters 1 according to the invention thus become mechatronic tools integrating intelligence and dedicated functionalities according to the applications developed on an on-board electronic card. With this type of interface 19, the concept of sealing and protection of the electronic card is all the more important that a contact of the card with the fluid 2 would damage the card and cause the loss of data stored in its memory .
    [0016] The general configuration of adapters 1 according to the invention is suitable for a wide variety of fluids, such as brake fluid, conditioned air fluid or cooling fluid. It is adapted according to the specificities of each one. However, each fluid has its peculiarities and requires a dedicated process, in particular in terms of process and flow, which has a direct influence on the choice of the hydraulic components integrated in the adapter and on the number of fluid connections between the adapter. 1 and the sheath 4. In addition, some applications require specificities such as the fact of embedding a sensor (eg vacuum) within the adapter 1 in order to make a measurement as close to the fluidic circuit 3 for to avoid certain disturbances of measurement such as the loss of the load resulting from the length of the sheath 4. According to an exemplary implementation of the invention, which is not limiting, a filling adapter 1 of a fluid 2 brake fluid for automobile. Adapter 1 has three fluidic links 6, 6 'and eight pneumatic links 7, 7'. The three fluidic links 6, 6 'are a brake fluid inlet 2, a re-suction for leveling the brake fluid reservoir 3 at the end of filling and a vacuum pipe. The filling duct and the re-suction duct are closed during rapid disconnection of the connecting block 9 and the body 10 of the adapter 1 by the assembly means 14, 15.
    [0017] The vacuum duct does not need to be plugged because it can not cause soiling (adapter change 1 is off-cycle, the vacuum duct is isolated). These three fast connections are placed at the rear of the body 10 of the adapter 1, just between the receptacles 14 locking "quarter turn". The pneumatic links 7, 7 'which make it possible to control the pneumatic valves dedicated to the process are grouped together at two different remote points from the point of the main fluidic connections 6, 6' in order to limit the force during the connection / disconnection. On the upper face of the body 10 of the adapter is the interface 19 control-command. It incorporates an electronic card embodying maintenance functions, process control buttons and LEDs (for example based on LEDs). It clings to the body 10 in a completely sealed manner with respect to the rear part of the body 10 where the fluidic connections are made. On this adapter according to the invention, the operator wanting to disconnect must first put the process out of cycle (for safety), it then turns a quarter turn the pins 15 integrated on either side of the adapter 1 forming a handle. It can then perform the fluidic disconnection and then the separation of the electrical connector 21. Since the brake fluid is corrosive, it is preferable to use a waterproof connector 21 which is disconnected separately. The operator can then do the maintenance operations he wants (change of the adapter 1, the interface 19, the joints inside the valves embedded in the adapter 1 ....). It performs the operations 10 described above in the reverse order for the reassembly of the adapter 1. Without this type of system, the operator should disassemble the entire duct 4, drain the hoses to perform maintenance operations. Upon recommissioning, it should purge the fluid lines, in particular the supply of brake fluid 2 to expel the air, as well as check the safety systems related to the sheath 4 (anti-tearing) in addition to winding. of these. In another exemplary embodiment of the invention, the adapter 1 is dedicated to the filling of heat transfer fluid to fill a variety of radiators coolant batch. Instead of using adapter rings to be placed on the radiators, that the operator mounts / dismounts each time on certain types of radiator 20 to ensure mechanical compatibility with the adapter 1, it suffices to make a change of adapter 1 by mounting the one dedicated to this type of radiator. The operator saves time, avoids the repetitive operation of putting and removing the adapter ring at each cycle and avoids problems such as sealing defects between the adapter part 1 and the fluid circuit 3.
    [0018] According to another non-limiting example of implementation of the invention, the adapter 1 is dedicated to the leak test of a fluid circuit 3 by means of a gas. In this case, we have a single conduit to fill the fluidic circuit 3 with a test gas 2. A sensor is integrated in the adapter 1 to measure the pressure at the beginning and end of the test. Thus, the measurement is made closer to the circuit and the leakage measurement is all the more reliable. Depending on the nature of the test gas, a second recovery line for discharging the gas to the outside may be added. The goal is generally not to disturb a measurement following the rejection of the gas from the previous test. In addition to these descriptions, it should be noted that the adapter 1, the connection and quick assembly members 12, 12 ', 28, 28', 14, 15 and the integrated hydraulic equipment 35 must be dimensioned according to the conditions of use (pressure, 3031160 14 temperature, nature of the fluid (s) ...). Indeed, the adapter 1 is carrying different equipment. It is recalled that the present description is given by way of non-limiting example of the invention. Thus, the invention is not limited to an adapter 1 for an application to the automotive sector. The adapter according to the invention is also applicable to all sectors requiring fluid transfer tools, particularly in the energy sector for filling heat pumps, heat transfer radiators ...
