    CONNECTOR FOR HYDRODYNAMIC APPLICATIONS TEAM
    AT LEAST ONE DETECTION SENSOR
    The present invention relates to a quick connector for hydrodynamic applications, in particular for hydraulic circuits or the like, comprising a female connector and a male connector. In particular, the present invention relates to a quick connector of the push-pull type, wherein the male and female connectors are formed so as to be connected and disconnected reciprocally by means of pushing and pulling actions, respectively. In more detail, the present invention relates to a quick connector of the aforementioned type suitable for use in the agricultural sector, in particular for the use of agricultural machines in which the respective connection of the hydraulic circuits of a main tractor and the machine or the tool or accessory used on each occasion is provided. In even more detail, the present invention relates to a fast connector of the aforementioned type comprising an innovative solution for detecting at least a portion of the parameters and / or values of work and / or operation of said quick connector.
    Prior art is known fast connectors for reciprocally connecting hydraulic circuits by means of flexible pipes. For example, quick connectors of the push-pull type are known for reciprocally connecting the hydraulic circuits of a main tractor and a tool, respectively, in which the connection and disconnection of the male and female connections is obtained at the same time. means of thrust and traction actions, respectively. In addition, the male and female connectors of the quick connectors are formed such that a mechanical connection (for example by pushing, generally on the male connector, in the case of push-pull connectors) of the male and female connectors results in the automatic positioning of the respective valve assemblies in the open position (and thus in hydraulic connection, which makes possible the flow of liquid between the two male and female connections), while the disconnection (by traction, usually on the connection male, in the case of push-pull connectors) male and female couplings results in the automatic repositioning of the male and female valve assemblies in the respective closed positions (in which the hydraulic circuits are closed and separated and the flow of liquid between the two male and female connections is impossible).
    The risk of a bad connection and / or accidental disconnection of the male and female connectors, or even an incorrect or partial opening of the valve assembly of one of the male and female connectors or both is also well known , especially in the case of push-pull connections.
    Similarly, the risks associated with the use, in particular prolonged use, of a hydraulic circuit in which the parameters and / or values of the circuit itself do not comply with the operating specifications of the circuit, or even are out of control, are known. For example, each hydraulic circuit is calibrated and sized according to a maximum pressure of the liquid, for example oil, in which an oil pressure that is greater than the maximum allowable pressure is likely to lead to the rupture of components of the circuit, for example the bursting of the hydraulic lines, or to cause them to fail. The same applies to the temperature of the oil, serious damage to the circuit and / or its parts being likely to result also from excessive temperature of the oil.
    The current switching machines, particularly those of the agricultural sector, are obviously equipped with devices designed to allow adjustment of the hydraulic circuit; for example, there are known solutions according to which the user can adjust at least some of the parameters of the circuit according to the requirements and / or circumstances through a touch screen type interface. Still as an example, in the case of a front-end harvester applied to an agricultural tractor, solutions are known which enable a user to adjust the lifting and / or lowering speed, for example by adjusting it on low values in the case of extremely heavy and / or delicate loads.
    However, the known solutions do not allow direct monitoring of the main parameters of the circuit, in particular at the various fast connectors of the circuit itself. For example, there is no known solution that can monitor the actual connection of the male and female connections in terms of fluid dynamics. Indeed, to date, the user can realize that the connection of the connectors of a connector is missing or incorrect only when it is impossible to obtain the desired action. In practice, the user realizes that the male and female connectors of a particular connector are disconnected or incorrectly connected, only if he realizes that the requested operation, for example the lifting of the front loader and / or or the rotation of a rotary tool, is impossible. However, these are clearly indirect commands, in which the user, faced with the impossibility of obtaining the desired operation, must act by deduction and look for the real reason for the lack of response from the circuit and / or a possible failure.
    The main object of the present invention is to eliminate, or at least limit, the disadvantages presented by the solutions according to the prior art.
    In particular, the object of the present invention is to propose and provide a solution that allows the direct monitoring of at least the main parameters of a hydraulic circuit, in particular at the level of a connector, for example a quick connector and / or push-pull type.
    Another object of the present invention is to provide a solution that directly determines that the connection of the connectors of a connector, particularly a quick connector, is incorrect.
    Another object of the present invention is to provide a solution of the aforementioned type which is characterized by reduced costs, and which can be manufactured and installed by means of simple and fast operations, and in which its installation on connectors of a type known does not require any modification, or at least no significant modification, the connectors themselves.

    In the following pages, the present invention will be explained by means of the following detailed description of the embodiments shown in the drawings. However, the present invention is not limited to the embodiments described below and shown in the drawings; conversely, all variants of the embodiments described hereinafter and shown in the drawings which will become apparent to those skilled in the art are within the scope of the present invention.
    In the drawings: - Figure 1 shows schematic views of possible applications of the present invention; - Figure 2 shows a schematic view of a first embodiment of the invention; FIG. 3 is a schematic view of an embodiment of the present invention; - Figure 4 shows schematic views of possible implementations of the present invention; - Figure 5 shows a schematic view of an embodiment of the present invention.
    In FIG. 1, the numerical references 100 and 200 designate an agricultural tractor and a tool or accessory, respectively, in particular a tiller adapted to be used by means of the tractor 100, in which the examples represented in FIG. non-limiting, the applications of the present invention (see description below) is not limited to the agricultural sector but also comprising switching machines and tools, accessories and machines from other sectors such as, for example, those of the earth moving, building and / or demolition machines, and the like. Similarly, the tractor 100 is shown as being equipped with a front loader 201 (see the inset of Fig. 1b). The tool (tiller) 200 as the front loader 201 for performing given operations exploit the hydrodynamic power made available by the tractor 100 and, to do this, the hydraulic circuits of the tool (tiller) 200 and the loader front 201 are connected to the hydraulic circuit of the tractor 100 by hydraulic hoses (flexible, in the example shown) 31 and 32 in the case of the tool (tiller) 200 and 31 to 34 in the case of the front loader 201 .
    For this purpose, as shown in Figure 2, the tractor 100 is equipped with a terminal assembly 101 (also called valve assembly or hydrodynamic distributor) of the respective hydraulic circuit, the assembly 101 being provided for connecting the hydraulic circuit of the tractor 100 the hydraulic circuits of tools, accessories and / or machines (such as the tool, in particular the tiller 200) applied to the rear of the tractor (for example by means of the three-point connector, but also towed). Other terminal assemblies may be provided for tools, accessories and / or machines applied to the tractor at the front and / or laterally, as in the case of the front-end loader 201. Characteristics and / or methods of coupling and / or connecting the rear terminal assembly 101 will be described hereinafter, for the sake of brevity since the following description also applies to different terminals, for example to side and / or front terminals.
    As shown in FIG. 2, the terminal or valve assembly 101 comprises a plurality of female connectors 11, 12, each of which can be mechanically and hydraulically connected to a corresponding male connector 21, 22. The methods for mechanically and hydraulically coupling the connections 11, 12 respectively with the connections 21 and 22 vary according to the type of connection; some are also substantially known and therefore, for reasons of conciseness, no detailed description is provided here. It is only indicated that a hydraulic connection is established between the circuits respectively upstream of the female connectors 11, 12 (in the illustrated case) and downstream of the male connector 21, 22 (again in the illustrated case) by mechanically coupling the male and female connectors and the valve assembly 101 may comprise the male and / or female fittings, and the tool or apparatus 200, 201 may be correspondingly equipped with the male and / or female fittings, respectively.
    The present invention finds an advantageous use in the case of multiple connectors provided with a plurality of connectors that allow the simultaneous connection of said connectors to those of a mobile terminal of a tool and / or an apparatus.
    Figure 3 shows the innovative concept underlying the present invention.
    As can be seen, the female connector 11 is equipped (according to the solutions and / or the methods described in more detail below) with a detection sensor 111, the male connector 21 being itself equipped with a 121. Of course, in the case of a multiple terminal, each of the respective connectors may, according to the invention, be equipped with a corresponding sensor, and moreover, according to the present invention, even only one of the male and female connectors. female connector can be equipped with a sensor.
    The sensors 111 and 121 (or at least one of them) are configured to monitor the actual operation and / or conditions of use of the connector; in particular, according to the invention, the data that can be detected by the sensor 111 and / or the sensor 121 comprise: the absence or the presence of a flow of liquid between said male 21 and female connectors 11, the value of pressure of said liquid inside said connector, the temperature value of said liquid inside said connector, the total time of presence of the liquid between said male and female connectors 11.
    Alternatively or additionally, the sensor 111 and / or the sensor 121 may be configured to detect and / or verify that the hydraulic connection is correct or incorrect between the male 21 and female connectors 11. In addition, the sensor 121 may be configured in order to detect the pressure of said liquid inside said male connector 21 and in the absence of connection between said male 21 and female connectors 11.
    Referring again to FIG. 3, the numeral 300 denotes a communication control unit or unit specifically configured to at least receive the data detected by the sensors 111 and / or 121 from the sensors themselves and summarized above.
    In particular, according to the present invention, the communication between the control unit 300 and the sensors 111 and / or 121 (unidirectional, at least sensors to the control unit, but possibly also bidirectional, sensors to the unit and vice versa) can be done wirelessly, especially in BLUETOOTH mode, but possibly via WiFi.
    In addition, according to the present invention, a communication is provided (wired or wireless, for example by BLUETOOTH, but possibly by WiFi), between the control unit 300 and a control unit accessible to a user, for example provided in the tractor cabin 100 and equipped with an interface for viewing the data collected by the sensors and / or configured to allow the entry of instructions and / or requests by the user, for example through a technique of touchscreen.
    In addition, the control unit 300 may be provided with a computing and / or processing unit for processing the data transmitted by the sensors 111 and / or 121, for example to extrapolate the data themselves and / or to calculate weighted averages, develop statistics or perform similar operations.
    Next, according to one embodiment of the present invention, an application that can be downloaded to a smartphone and / or a tablet is also provided for the remote management of the control unit 300, that is to say for display the data processed by the control unit 300 and / or enter instructions as through the control unit provided in the cabin.
    Figure 4 shows two possible solutions to integrate the sensors in the male and / or female connectors.
    In particular, according to the solution of FIG. 4a, the sensor 111 (not shown in the figure) accommodates in the internal space defined by a hollow element 110, itself screwed onto the female connector 11, the sensor 121 (not shown in the figure) similarly housing in the internal space defined by a hollow member 210 of the male connector 21.
    The solution according to FIG. 4b is substantially similar to that of FIG. 4a, where FIG. 4b shows a male connector 21 and a corresponding "flat-face" type female connector 11, the sensors 111 and 121 also housing, in this case in the internal spaces defined by respective hollow elements 110 and 210 of the male 21 and female 11 connectors.
    FIG. 5, on the other hand, shows a possible solution for applying sensors to connectors that are devoid of hollow elements defining an internal space able to receive one or more sensors. In this case, as can be seen, there is provided an additional hollow member 220 which is externally applied to both the female connector 11 and the male connector 21, said additional hollow member being formed to define the internal space adapted to house the sensor (not shown in the figure).
    It has thus been demonstrated, by means of the above detailed description of the embodiments of the present invention shown in the drawings, that the present invention made it possible to achieve the predetermined objects by eliminating the disadvantages of the prior art.
    In particular, the present invention allows the direct monitoring of at least the main parameters of a hydraulic circuit, in particular at a connector, for example a quick connector and / or push-pull type.
    In addition, the present invention also provides a solution for directly verifying that the connection of connectors of a connector exists or is missing or even incorrect, characterized by reduced costs, and which can be manufactured and manufactured. installed by simple and fast operations, and whose installation on fittings of known type does not require any modification, or at least no significant modification, the connectors themselves.
    Although it has been explained above by means of a detailed description of the embodiments shown in the drawings, the present invention is not limited to the embodiments described above and shown in the drawings. Conversely, all modifications and / or variations of the embodiments described above and shown in the drawings will become obvious and immediate to those skilled in the art are within the scope of the present invention.
    For example, the number and type of sensors and the data that can be detected by them are likely to vary within the scope of the present invention, depending on the needs and / or circumstances.
    The scope of the present invention is thus defined by the claims.
