Definitions
- the present invention relates to a valve for dispensing a fluid, a fluid dispensing device comprising this valve, and a method of parameterizing this valve.
- a fluid valve such as for example a pneumatic solenoid valve, comprises several orifices for the admission or the outlet of the fluid, and means for switching and controlling the circulation of the fluid under pressure.
- a fluid dispenser is traditionally configured to perform a single predetermined fluid delivery function, i.e., in response to a same control signal, the fluid valve distributes this fluid at the outlet always in the same manner through the base on which this valve is mounted.
- a disadvantage of these conventional fluid dispensing devices is that it is necessary to change the valve each time the user wishes to change the function executed at the output. This therefore requires the user to have a valve by function, which generates constraints in terms of inventory, maintenance or change of production rate.
- the present invention aims to overcome this disadvantage by providing a fluid distribution valve capable of performing a plurality of distinct functions.
- the subject of the present invention is a valve intended to be mounted on a base in order to control the distribution of a fluid, this valve comprising a housing and a plurality of orifices, these orifices being intended for entry or exit.
- fluid within the housing characterized in that the valve comprises a plurality of distributors arranged in the housing to control the flow of fluid within the valve, and in that the valve comprises an electronic card arranged in the housing, the electronic card being configured to store a truth table associating with each control signal received by the valve a predetermined positioning of the distributors.
- the positioning of the distributors in response to an input signal depends on the truth table stored by the electronic card, so that the valve according to the invention is capable of performing alone several distinct functions, a function being defined by a truth table. There is no need to change the valve to change function as is the case in the state of the art. It is enough to modify the function recorded by the electronic card. It should also be noted that the valve according to the invention operates autonomously and transparently for the user, the external control signals remaining standard.
- the device comprises connection means configured to enable the electronic card to be connected to a user terminal in order to transfer a truth table from the user terminal to the electronic card.
- the device comprises fluid recycling means configured to recover at least a portion of the fluid purged by one of the distributors for reuse.
- the electronic card is configured to manage a mode of transition of the distributors from one position to another.
- the transitions from one state to another are defined by technological choices and the mechanical arrangement of the valve in question, and are thus immutable.
- the switchover from the state in which a first output port is put to the pressure and a second output port to the exhaust, to the state in which the first port is put in the exhaust and the second pressure port, or vice versa is performed synchronously because the mechanical construction generally employed combines and binds together the fluid passage institutions.
- the use of the electronic card for controlling the plurality of distributors in relation with the truth table implemented via the user terminal, makes it possible to adapt the changes of states according to the user's need, and thus to provide temporal or conditional offsets, adjustable and modifiable.
- the valve comprises means for measuring pressure or flow connected to the electronic card. This makes it possible to optimize the transfer of fluid from one dispenser to another so as not to have a detrimental impact on the response time of the valve to an input signal, particularly in the case of fluid recycling.
- the differential pressure measurement between the outlets or that of the fluid flow makes it possible to adjust and optimize the time required to recycle fluid, while respecting the desired cycle time.
- This arrangement also makes it possible to implement conditional offsets based on pressure or flux values during transitions from one state to another. These parameters are internal to the valve and managed by the PCB and therefore do not require additional hardware in the user's installation or additional external control logic.
- the valve comprises an electrical energy storage element embedded in the housing and configured to supply the electronic card with energy.
- valve offers more opportunities for use, and is also compatible with systems already installed, as part of maintenance or improvement.
- the electronic card is arranged at least partly above the distributors.
- This positioning of the electronic card allows not to impact the width or length of the valve, so to benefit from a housing retaining a standard size for connection to a base despite the presence of the electronic card.
- the device comprises five orifices.
- This feature allows two ports to be used as pressurized fluid inlet ports and a single port as a bleed port. Thus, this allows the input use of a differentiated pressure.
- the device comprises four distributors two orifices two positions.
- This configuration with four 2/2 distributors allows the realization of a multitude of functions with standard distributors and inexpensive.
- the distributors comprise a bistable actuator.
- An advantage of using bistable actuators is to reduce power consumption because switching from one position to another is controlled by a biased pulse signal, i.e., positive voltage pulses. or negative respectively responding to the rising or falling edge of a positioning command.
- the distributors comprise a proportional actuator.
- the invention also relates to a fluid distribution assembly comprising a valve according to one of the preceding claims and a user terminal comprising a plurality of truth tables.
- the user terminal comprises a program configured to allow a user to create a truth table and / or a transition mode.
- the user can create functions, or truth tables, not existing in the library of truth tables, and adapted to his own needs.
- the invention also relates to a method of using a valve having the aforementioned characteristics, comprising the steps of:
- This method allows a user to modify at his discretion and according to his needs the function performed by the valve according to the invention.
- a step of selecting a truth table from a library of predetermined truth tables or creation of a truth table via a program executed by the user terminal prior to the transfer step, a step of selecting a truth table from a library of predetermined truth tables or creation of a truth table via a program executed by the user terminal.
- the method comprises the use of two openings of the housing for the admission of pressurized fluid and a single orifice of the housing for purging the fluid.

- the electronic card 6 can be positioned above the distributors 4 with respect to an axis A substantially orthogonal to the connection face 20 of the housing 2.
- the valve 1 may comprise at least four orifices O, preferably five, including at least one orifice 01 for supplying pressurized fluid allowing the valve 1 to be fed with pressure fluid, two fluid outlet ports 02, 04 to one or more actuators (not shown) such as a cylinder, and at least one exhaust port, preferably two orifices 03, 05 exhaust for purging the valve 1 of the fluid flowing there.
- the electronic card 6 comprises a microprocessor configured to translate each control signal received by the valve 1 into a control signal controlling a predetermined positioning of the distributors 4, according to the truth table 60 stored.
- the microprocessor therefore controls a positioning of the distributors 4 according to the truth table 60 stored.
- the valve 1 comprises connection means configured to connect the electronic card 6 to a user terminal 8 which stores a library of predetermined truth tables 60, such as a computer, a tablet, a mobile phone, or an PLC programmable logic controller (PLC), in order to transfer to the electronic card another table of truth.
- the valve 1 is configurable according to the needs of the user.
- the connection means may be wired, such as a connection port 22, for example of the M12 or USB connector type, and / or wireless, such as a Bluetooth or Wifi communication unit 24.
- the connection port 22, in particular the connector M12 is advantageously located on an upper face of the valve 1, that is to say opposite to a lower face intended to be connected to the base and where the ports 0 are arranged. , preferably the closest to the electronic card 6.
- the connection means may include a gateway 21 of the IO-link type, making it possible to connect the valve 1 to the user terminal 8, in particular to the controller 110, for the parameterization of the valve 1 and / or the power supply of the electronic card 6.
- the gateway 21 of the IO-link type enables bidirectional communication: from the user terminal 8 to the valve 1 for sending and receiving truth tables 60, from the valve 1 to the terminal 8 user for status data such as the state of activation of the outputs through the pressures at the outlets, the number of cycles performed or even the leakage levels or the response times by measurement of the pressure variations.
- the distributors 4 correspond to elementary functional blocks.
- the distributors 4 are arranged inside the housing 2.
- Each distributor 4 can connect at least two orifices 0 of the valve 1 in order to control the circulation of the fluid inside the valve 1.
- the distributors 4 may be pneumatic or hydraulic distributors, for example solenoid valves.
- Each distributor 4 may comprise a body, a member (drawer or valve) movable within the body between at least two positions and an actuator 14, 45, 12, 23, for example a solenoid, configured to move the movable member .
- the actuators are connected to the electronic card 6, as shown symbolically in FIG.
- the distributors 4 are standard distributors.
- the distributors 4 may be 3-position or 3-position type distributors (FIG. 8A) or two 2-position orifices (FIG. 7A).
- the valve 1 may comprise, for example, a configuration with at least four 2/2-type distributors 4 (2 orifices, 2 positions), as represented in FIG. 7A.
- the distributor 4a communicates the orifices 01 and 04, the distributor 4b the orifices 01 and 02, the distributor 4c the orifices 04 and 05, and the distributor 4d the orifices 02 and 03.
- By combining the actions of the distributors 4a, 4b, 4c and 4d it is possible to reproduce any type of standard dispenser, and in addition to add functions.
- FIG. 8 illustrates a standard dispenser 100 of the 5/3 type (5 orifices, 3 positions) whose central position is with plugged orifices.
- This standard dispenser is also called a 5/3 closed center dispenser.
- This standard distributor offers three distinct states. According to a first state, the two control signals for the drivers 14, 12 are inactive, the distributor 100 is in the central position (FIG. 8). In a second state, the control signal of the driver 14 alone is active, the distributor 100 has switched to the left block (has therefore moved to the right from the position of Figure 8). According to a third state, the control signal of the driver 12 alone is active, the distributor 100 has switched to the right block (has therefore moved to the left from the position of Figure 8).
- valve 1 with the configuration of Figure 7A can affect a different result depending on whether the two control signals are active or inactive simultaneously.
- FIGS. 7C and 7D when the two control signals are inactive, the valve 1 takes the equivalent of a central position where all the orifices 0 are plugged; but when both control signals are active simultaneously, the valve 1 takes a central position said open center exhaust, in which the orifices 02 and 04 are respectively in communication with the orifices 03 and 05.
- the truth table 60 associates with each combination of control signals a control signal activating or not the actuator 14, 45, 12, 23 of each of the distributors 4a, 4b, 4c, 4d.
- the electronic card 6 may be configured to handle a mode of transition of the dispensers 4 from one position to another, among a plurality of transition modes or combinations of possible transition modes.
- the microprocessor of the electronic card 6 can be configured to decide on the order of opening or closing of the fluid circulation channels of the valve 1.
- the valve 1 may include means for measuring pressure or flow, such as pressure sensors 16, connected to the electronic card 6.
- the pressure or flow measurement means may be arranged to measure a pressure or a flow rate at the outlet orifice (s) 02, 04, as shown in FIG. 7E.
- the valve 1 may advantageously comprise fluid recycling means configured to recover at least a portion of the fluid purged by at least one of the distributors 4 when the distributor moves to another position. The recovered fluid is redirected to a second distributor 4 during the transition controlled by the control signal triggering the change of state.
- the fluid recycling means may comprise a fluid recovery distributor 18, which connects, for example, the outlet orifices 02, 04.
- the fluid recovery distributor 18 is moreover connected to the distributors 4.
- the switchover from the state in which the first output port is put to the pressure and the second output port to the exhaust, to the state in which the first port is put in the exhaust and the second pressure port, or conversely, is done in three stages: the switching of the distributor 18 is first opened to allow the exchange of fluid between the output ports to the reaching a conditional pressure or flow threshold; the switching of the distributor 18 is then returned to the closed position, before the appropriate distributor 4 is activated to complete and complete the establishment of the fluid passage.
- the fluid recovery distributor 18 can be a distributor similar to the distributors 4, in order to reduce the cost of the valve 1. According to the example of FIG. 7B, the air recovery distributor 18 is thus of type 2. 2, two holes two positions.
- the actuators of the distributors 4, and if appropriate of the fluid recovery distributor 18, may comprise an electromagnet, for example a solenoid.
- the actuators of the distributors 4, 18 may be of the monostable type, also called "all or nothing". These actuators have a stable state which corresponds to the non-excitation of the electromagnet and thus to the state of rest, and an unstable state depending on the excitation of the electromagnet and corresponding to the establishment of the control signal.
- Activation of the actuator managed by the electronic card 6 requires the maintenance of the piloting signal; this can however be optimized by the application of an advanced electrical signal, either at two levels, namely a call voltage then a holding voltage, or switching, namely pulsed at an appropriate frequency (modulation of Pulse Width or Pulse Width Modulation).
- the actuators of the distributors 4, 18 may be of the bistable type. These actuators have two stable states, one corresponding to the state of rest and the other to the state of establishment of the control signal. The switching from one state to another is done by the application of a polarized pulse signal. The transition from one state to another is done by detecting a rising or falling edge of the control signal. This type of actuator reduces the energy consumed.
- the actuators of the distributors 4, 18 may be proportional type. These actuators make it possible to adopt a relative state between the state of rest and the state of establishment of the complete control signal, in proportion to a recorded electrical control signal (0-10V or 5-20 mA). These actuators therefore allow pressure regulation.
- the electronic card 6 is configured to deliver to each actuator the appropriate pilot signal.
- Valve 1 may further include feed means configured to provide the electronic board with a constant power source for operation thereof.
- the power supply means may include a power supply port 24 for connecting a power supply cable.
- the power supply means may comprise an electrical energy storage element 26 embedded in the casing 2 and configured to supply the energy necessary for the operation of the electronic card, such as for example a battery or a capacitor. . This could be particularly advantageous with bistable actuators of the distributors 4, 18.
- a valve conforming to ISO 15407-2 or 5599-2 includes a four-point electrical connector, three of which are used for the transmission of control signals. The fourth contact of this connector can thus be exploited to bring the continuous energy source necessary for the operation of the electronic card 6, thus serving as a power supply port 24.
- the valve 1 can be compatible with the ISO 15407 standard. 2 or 5599-2 and can be mounted on standard bases, since the three connection points defined in the standard remain unchanged. As illustrated in FIGS.
- the invention also relates to a device 50 for distributing a fluid comprising a valve 1 as described above, as well as a user terminal 8, such as a computer, a tablet, a mobile phone or PLC programmable logic controller (PLC), which stores a library of predetermined truth tables 60.
- the user terminal 8 includes an interface allowing the user to select a truth table 60 in the truth table library 60.
- the user terminal 8 includes a program advantageously configured to further enable a user to create a truth table 60 and add it to the truth table library 60 via the user interface.
- the program can be configured to allow the user to define a transition mode.
- the user can create functions, or truth tables, not existing in the library of truth tables, and adapted to his own needs.
- the valve 1 is thus programmable.
- the invention also relates to a method of parameterizing the valve 1 described above. This process comprises the steps of:
- the method may include a step of selecting by the user of a truth table 60 from a library of predetermined truth tables 60 stored on the user terminal 8. .
- the user has access to a prerecorded library of functions, hydraulic or pneumatic, commonly used.
- the preceded may include a step of creating a truth table 60 via a program installed on the user terminal 8.
- This truth table 60 can be added to the truth table library 8 of the user terminal 8. The user can thus parameterize valve 1 with very specific and non-existent functions.
- the method may also include a step of creating a transition mode by the user via the program installed on the user terminal 8.
- the user can specify and modify transition modes when the valve 1 moves from one position to another, which is not possible with the standard valves.
- the user can define the order of opening or closing of the fluid circulation channels in the valve 1, during the transition from one state to another.
- valve 1 is for example not limited to an arrangement of four or five distributors 4, 18 type 2/2, but could include a arrangement of two or three valves 4, 18 of type 3/3, three orifices, three positions, as shown in FIGS. 8A and 8B.
