Definitions
- the invention relates to a fluid power control device with a plurality of valve modules arranged in succession in a row and combined to form a battery-like unit, each of which contains a main valve equipped with at least one movable valve member and at least one electrically actuable valve drive for the main valve.
- DE 299 09 529 UI shows different variants of such a control device, with several valve modules always being combined to form a battery-like unit and the unit either being self-supporting or being placed on a plate-like module carrier.
- the valve modules each contain a main valve that serves to control pressure medium under positive or negative pressure and at least one electrically actuable valve drive that serves to control the main valve.
- control units are used in complex machines, there is a need for precise monitoring of the operating status of the main valves.
- monitoring has mostly been done visually using optical display means which visualize the switching state of the valve drive.
- the switching state of the valve drive does not necessarily result can be concluded on the operating state of the assigned main valve. Due to malfunctions, the main valve may not be switched over, for example, although the valve drive has been activated accordingly.
- a diagnostic module designed to detect at least one operating state of one or both of the adjacent main valves is placed.
- the operating state of one or more main valves can be precisely recorded while maintaining the compact dimensions of the valve modules.
- At least the majority of the measures required for the detection are implemented in the diagnostic module, while no or only a few structural changes are required on the main valve itself compared to a conventional design.
- the main valve can usually be operated either in conjunction with or without a diagnostic module, which allows a very flexible construction of fluid power control devices.
- the placement of the diagnostic module or modules between adjacent valve modules results in immediate proximity to the status information to be recorded, which promises high precision. Since valve modules combined to form battery-like units are often arranged at a short distance from one another at home, the diagnosis can be carried out without an extreme increase in the overall dimensions of the Realize control unit.
- very precise condition monitoring can be carried out by detecting at least one operating condition of the main valve or valves, which favors integration into the circuit of an electronic control.
- each diagnostic module will be designed to record operating data for only one main valve at a time.
- the diagnostic module in such a way that it can record the operating state of both main valves flanking it. In this way, the number of diagnostic modules to be used can be reduced.
- the signals output by the diagnostic modules are expediently output via an electrical interlinking device, to which the valve modules or their valve drives are also connected. In this way, the internal wiring effort is not increased or is increased only insignificantly.
- diagnostic modules are possible, inter alia, in control units in which the battery-like unit containing the valve modules is penetrated by at least one fluid channel, which is made up of aligned channels. channels of the individual valve modules. Diagnostic modules are then used which have appropriate through-channels, so that the desired fluid channel, in particular for a central supply and / or removal of pressure medium, is still available.
- Such through-channels can be dispensed with in the diagnostic module if the valve modules are not directly fluidly linked to one another, but instead sit together on a plate-like module carrier which takes on the task of fluidically linking the individual valve modules.
- the diagnostic modules are expediently integrated into the already existing electrical interlinking of the valve modules.
- the diagnostic modules expediently have a flat shape and are in particular disc-shaped or plate-shaped. They are placed between neighboring valve modules in such a way that their expansion plane is perpendicular to the row direction.
- the existing diagnostic modules are expediently provided with suitable sensor means, which can detect the desired operating state of the adjacent main valve or valves and output the corresponding sensor signals.
- Sensor signals can be fed directly to central control electronics placed on board the control device or externally, or in the form of prepared diagnostic signals, for which purpose a respective diagnostic module can have its own evaluation electronics.
- Certain state variables of a main valve for example the switching position of the valve member, can be detected when using suitable sensor means without direct access to the interior of the main valve in question. This applies to for example for a contactless switch position query using in particular inductive proximity sensors.
- the relevant main valve expediently has a tap opening that is open towards the diagnostic module, but is covered by the relevant diagnostic module, so that no external interference takes place. If the main valves are directly provided with through-channels running in the row direction, one or more of these through-channels can be used as tap openings for the condition detection.

- FIG. 5 shows an individual perspective view of a diagnostic module from the control device according to FIG. 3.
- FIGS. 1 and 2 on the one hand and FIGS. 3 to 5 on the other hand show two different embodiments of the fluid power control device 1 according to the invention, which can be used to control a machine, a system or individual work tools, the devices to be controlled being operated by fluid power, in particular pneumatically , If required, the control units 1 can additionally be equipped with components (not shown in more detail) which enable the control of electrical devices.
- the control devices 1 shown have in common that they contain a plurality of valve modules 2 which are arranged in succession in a row direction 3 indicated by a double arrow and are combined to form a battery-like unit 9.
- a plurality of diagnostic modules 4 preferably of disk-like or plate-like design, are provided, one of which is placed between two valve modules 2 which follow one another in the row direction 3.
- the diagnostic modules 4 are oriented in such a way that their expansion planes run at right angles to the row direction 3.
- Valve modules 2 which are directly adjacent to one another in the row direction 3 are thus arranged at a distance from one another and define a gap-like intermediate space 5 between them, in each of which a diagnostic module 4 is seated.
- a termination module 6, 7 connects to the two outer valve modules 2a, 2b.
- tie rods 8 extending between the two termination modules 6, 7, the components of the unit 9 are firmly clamped together in the row direction 3, so that the Control unit 1 represents a self-supporting assembly.
- other mechanical connecting elements could also be used.
- the battery-like unit 9 composed of the valve modules 2 and the diagnostic modules 4 sits together on a strip-like or plate-like module carrier 12. It is possible to make the components of the battery-like unit 9 comparable to the design according to FIG. 1 to form a self-supporting structural unit summarize and fix them as such on the module carrier 12. However, the design shown is preferred, in which at least the valve modules 2 are individually attached to the module carrier 12.
- the diagnostic modules 4 can each be fixed to one of the valve modules 2 flanking them and fastened to the module carrier 12 via this, but there is also the possibility, alternatively or in addition, of providing individual fastening of the diagnostic modules 4 to the module carrier 12.
- the appropriately block or plate-shaped valve modules 2 each contain a main valve 13 and an electrically actuable valve drive 14 arranged thereon.
- a plurality of valve drives 14 can also be arranged on the main valve 13 and integration into the main valve 13 is also possible.
- the valve drive 14 works in particular on an electromagnetic or piezoelectric basis.
- the actuation of the associated main valve 13 can be actuated, which is to say more precisely that the switching position of a valve member 16 which is adjustably mounted in the main valve housing 15 is predetermined as required.
- the valve member 16 is in particular a valve spool, preferably a piston spool. It is operated Expediently in pilot-controlled form, the valve drive 14 being part of a pilot valve, through which the valve member 16 can be acted upon by a pilot fluid in order to specify the switching position.
- the main valve 13 could also contain several valve members.
- the valve member 16 is located in a receptacle 17 in the interior of the main valve housing 15.
- Two working channels 18a, 18b communicate with this receptacle 16, which open to one of the outer surfaces of the main valve housing 15 oriented at right angles to the device 3 and to which fluid lines (not shown in more detail) can be connected which lead to a consumer to be actuated, for example to a drive actuated by fluid power.
- the receptacle 17 also communicates with a feed channel 22 and at least one relief channel 23, two such relief channels 23 being provided in the exemplary embodiment. Pressurized fluid is fed in via the feed channel 22 and is guided into one or the other working channel 18a, 18b in accordance with the switching position of the valve member 16.
- the relief channels 23 communicate with the atmosphere and serve for the backflow of the used fluid from the connected consumer. If the control unit 1 is operated with compressed air, as is the case in the exemplary embodiment, the relief channels 23 each form a ventilation channel.
- a central supply and discharge of pressure medium to and from the valve modules 2 is provided.
- a plurality of which extends in the row direction 3 fluid channels 24, 24b form a central feed channel 24a and two central discharge channels.
- the fluid channels 24 open out at a connection surface 25 of the module carrier 12.
- Branch channels 26 extend from the aforementioned fluid channels 24 and open out to the surface of the module carrier 12, referred to as the mounting surface 27, on which the components of the battery-like unit 9 are fixed.
- the branch channels 26 leaving the supply channel 24a communicate with the feed channels 22 and the branch channels 26 leaving the discharge channels 24b communicate with the relief channels 23 of the individual valve modules 2.
- the central fluid channels 24 run directly through the battery-like unit 9 at the level of the main valves 13.
- These central fluid channels 24 are composed of aligned through channels 28a, 28b which penetrate the valve modules 2 and the diagnostic modules 4 in the row direction 3 and complement each other to form these central fluid channels 24.
- the through channels 28a simultaneously form the feed channel 22 and the relief channels 23, which in turn are part of the receptacle 17, so that the receptacle 17 containing the valve member 16 is practically penetrated by the central fluid channels 24.
- sealing means 32 are arranged which, in the case of modules braced in the row direction 3, effect a seal, so that no fluid undesirably passes between adjacent fluid channels or escapes to the environment ,
- the main valves 13 could, as already mentioned, also be equipped with a plurality of valve members.
- valve modules 2 of the exemplary embodiment are intended to distribute pressure medium under excess pressure, a design would also be possible which serves to distribute vacuum, it being possible for a vacuum generator to be integrated directly into the relevant valve module 2. If necessary, valve modules 2 for overpressure and for underpressure can be combined within a control unit 1.
- the diagnostic modules 4 are designed to detect at least one operating state of one or both main valves 13, from which it is flanked on opposite sides.
- both variants are illustrated, with three diagnosis modules 4a diagnosing on one side diagnosing the operating states of only one adjacent main valve 13, while a further diagnosis module 4b diagnosing on both sides diagnoses the operating states of both main valves 3 flanking it.
- the number of diagnostic modules 4 to be used can be reduced, the overall length of the control unit 1 being reduced at the same time, because in this case between one or more neighboring valve modules 2 there is a separate diagnostic module 4 can be dispensed with.
- this could mean according to FIG. 3 that the diagnostic module additionally provided with reference number 30a can be omitted if the diagnostic modules additionally designated with reference number 30b are designed to be diagnosed on both sides.
- the diagnostic modules 4 have an outline design so that they lie within the outline of the adjacent valve modules 2, which also means that the outlines are identical.
- the diagnostic modules 4 are equipped with sensor means 33, which are able to output sensor signals which can be further processed in accordance with the detected operating state.
- FIG. 5 shows an example of a diagnostic module 4 which is equipped with sensor means 33, which are position sensor means 33a, with which one or more switching positions of the valve member 16 of the main valve 13 of interest can be detected.
- These position sensor means 33a are, for example, proximity sensors which can be activated without contact and which respond to the valve member 16 or one or more actuating members arranged thereon. In particular, they can be inductive proximity sensors.
- the advantage of this type of position sensor means 33a is that they can detect the current position of the valve member 16 through the wall of the main valve housing 15.
- sensor means 33 place at least one tap opening on the main valve 13 to be diagnosed 34 ahead, via which the desired status information can be tapped and which is open to the associated diagnostic module 4 in order to perform sensory monitoring from there.
- FIG. 2 Such a design is shown in FIG. 2. It can be seen that the sensor means 33 are arranged there on the diagnostic module 4 in such a way that they come to rest on one of the tapping openings 34 when the modules are attached to one another.
- Switch position detection suitable additional position sensor means 33b provided in the diagnostic module 4, which have optical contact through a tap opening 34 to the valve member 16 and can thus determine the switch position.
- the sensory detection of the switching position of the valve member 16 can be used to determine exactly whether the main valve has switched. Comparable detection is possible through pressure detection, but possible detection can also
- one or more of the through-channels 28a of the main valve housing 15 which are open towards the diagnostic module 4 can be used as the tap opening 34.
- special tap openings 34 are preferably provided on the main valve housing 15. When operating without a diagnostic module 4, these tap openings 34 are then closed by the subsequent valve module 2.
- the tap openings 34 are normally closely covered by the assigned diagnostic module 4, so that no incorrect information regarding the status data can arise.
- connection openings 35 for the central fluid channels 24 are expediently located on one of the closure modules 7, which covers the open side of the adjoining main valve 13.
- the diagnostic modules 4 can in principle be designed such that they directly output the sensor signals generated by the sensor means 33.
- An embodiment is more expedient, however, in which the diagnostic modules 4 contain evaluation electronics 36, which evaluates the sensor signals received by the sensor means 33 and outputs them as processed detection signals. In this way, depending on the type of sensor means 33, each diagnostic module 4 can be equipped with a specifically suitable evaluation electronics 36.
- All valve modules 2 and diagnostic modules 4 are expediently connected to a common electrical interlinking device 37 for feeding in the actuation signals and energy required for the operation of the valve modules 2 and for returning the diagnostic signals from the diagnostic modules 4. Insofar as actuation signals and / or energy are also required for the operation of the diagnostic modules 4 are or is, this can also be fed in via the common electrical interlinking device 37.
- the electrical interlinking device 37 contains a conductor strand 39 consisting of several electrical conductors, which runs in the row direction 3.
- the modules 2, 4 mentioned are connected to it on the one hand.
- an electromechanical interface 38 arranged on the outer surface of the module carrier 12, for example a plug-in device, via which a connection to further control devices and / or external control electronics is possible. It can be a bus connection.
- FIGS. 1 and 2 illustrate that, on the other hand, the electrical interlinking device 37 can also be connected to a central control electronics 42 located on board the control unit 1, which outputs the actuation signals required for the operation of the valve modules 2 and which also uses the reported diagnostic signals.
- the central control electronics 42 is expediently part of an independent module and, in the exemplary embodiment, is formed by the one terminating module 6.

- at least the valve modules 2, but preferably also the diagnostic modules 4, are equipped with electronics which are capable of reading out and / or coming from the signals addressed to them. de to output addressed signals in the electrical interlinking device 37.
- the conductor strand 39 runs in the module carrier 12.
- Contact elements 43 are provided on the valve modules 2 and on the diagnostic modules 4, which come into contact with the conductor strand 39 with the correct assignment when the corresponding module is installed on the module carrier 12.
- the contact elements 43 can be designed to produce a purely pressing contact contact or else to produce a plug contact.
- the conductor strand 39 runs through the battery-like unit 9.
- the conductor strand 39 is composed of individual conductor strand elements which pass through the respective module 2, 4 and which are connected to interfaces 45 arranged at the two mutually opposite joining surfaces 44 oriented in the row direction 3.
- the mutually facing interfaces 45 of adjacent modules 2, 4 are in electrical connection and thus produce the electrical conductor strand 39.
- one or more diagnostic modules 4 can be equipped directly with status display means 46, which are able to display one or more of the detected operating states, in particular in an optical manner.
- the status display means 46 can in particular be LEDs.
- the sensor signals 33 generated directly by the sensor means 33 can of course also be output via the electrical interlinking device 37.
