Definitions

  • additional switching devices for example a clamping device or a brake for clamping or braking a force tap of the working device, valves for interrupting fluid connections, for example in the event of a fault or the like, additional lines must be laid between these devices and the higher-level control. Furthermore, it is necessary for the superimposed control device to generate separate switching commands for switching the safety valves or the clamping device.
  • the at least one switching output can be parameterized. For example, limit values of the sensor values, switch-off times or switch-on times, braking values, tolerances, for example voltage tolerances, or the like can be set as parameters.
  • the parameterization can be done via the control interface or via a separate, Parameterization connection provided specially for the parameterization.
  • the valve module expediently generates the switching signal itself, for example as a function of at least one sensor signal and / or a control signal generated by a control device.
  • the control device may be, for example, a local control device contained in the valve module or a superimposed external control device.
  • the sensor signal may be generated by an external sensor connected to the valve module, for example a position sensor on the implement.
  • the valve on board the valve module is preferably a switching valve and / or a continuous valve and / or a control valve. Particularly preferred is on board the valve module, a 5/3-way valve.
  • a 5/3-way valve fulfills the function of otherwise required 3/3-pressure control valves.
  • the center position of the directional control valve is the closed position.
  • control interface and the at least one switching output are advantageously connected to one another, so that the switching output can be actuated directly via the control interface.
  • a higher-level control on the control interface can send a switching signal for deactivating or activating the implement to the valve module. This signal is forwarded by the control interface directly to the at least one switching output. This is simplifies the control of the working device.
  • the cabling effort is low, in particular, no separate cables must be placed between the superimposed control device and the switching device.
  • the switching output may expediently comprise a digital and / or an analog switching output.
  • the respective switching state at the switching output can be reported on via the control interface, for example to a higher-level control.
  • the valve module is preferably a separately operable, so to speak, stand-alone valve module.
  • the valve module is designed as a module for a valve battery, which contains a plurality of valve modules lined up, input / output modules and the like.
  • a fluid power arrangement 10a includes a pneumatic drive 11a as a fluid power tool 12a.
  • the drive 11a is a linear drive.
  • the drive 11a is acted upon by a valve module 13a with fluid, in the present case compressed air, so that an actuator element 35a arranged in the interior of the drive 11a drives a carriage 15, which is guided externally on the housing 14 of the drive 11a, back and forth between end stops 16, 17.
  • connections 27, 28 for connecting the valve module 13a to other devices, e.g. Control and sensor devices provided.

  • a reliable and correct tubing or fluid connection between the devices 11a, 13a can be produced by appropriate, optional measures.
  • the device fluid port 18a and the valve module working port 20a have identical release rings 33 as a first mechanical coding.
  • Soldering rings 34 of the fluid ports 19a, 21a are mechanically different from the release rings 33 and thus form a second mechanical coding.
  • the release rings 33 continue to project in front of fluid connection bodies of the fluid connections 18a, 20a than the release rings 34 in the fluid connections 19a, 21a.
  • the fluid lines 22a, 23a and expediently also the fluid connections 18a, 20a or 19a, 21a have, for example, different color codes or corrugations, so that a clear color assignment from fluid line to fluid connection is provided.
  • the valve module 13a includes a valve 38 which is controllable via the control interface 36. Via the control interface 36, the valve module 13a receives position signals for a non-illustrated valve member of the valve 38.

  • the control device 39 evaluates sensor signals 47 obtained, for example, from pressure sensors 43, 44 and 45 of a sensor arrangement 46.
  • the pressure sensors 43, 44 are associated with the working ports 20a, 21a.
  • the pressure sensor 45 detects the supply pressure at the supply connection 24.
  • the sensors 43, 44 and 45 are assigned a pressure detection device 48, which preprocesses the sensor signals 47, for example for the control device 39, for example, adjusts levels, smoothes the sensor signals 47 or the like.
  • the valve module 13a not only pneumatically actuates the implement 12a, but also switches switching means 49a for deactivating the implement 12a.

  • the switching outputs 52a are integrated into the housing 26 of the valve module 13a.
  • the valve module 13a has the switching outputs 52a on board.
  • the valve module 13a sends via lines 54a or optionally also via a wireless interface 54b switching signals 54 for switching the switching valves 50 in their blocking position or passage position.

  • the valve assembly 51 forms a fail-safe valve assembly.

  • the valve module 13a generates the switching signal 54 in response to, for example, the pressure sensor signals 47. At an unexpected pressure drop at one of the working ports 20a, 21a, at a pressure loss at the supply port 24 or the like, the valve module 13a generates the switching signal 54 for switching the switching valves 50 in their Locked position, so that the implement 12a is turned off.
  • valve module 13a has a temperature control.
  • a temperature sensor 55 monitors the temperature of the valve module 13a, for example the valve 38 or a power supply 61 of the valve module 13a.
  • the temperature sensor 55 generates a temperature sensor signal 56, which receives the switching output device 53 at an input interface 57.

  • the position sensor 31 generates a position sensor signal 58.
  • the switching output device switches For example, when a limit position is exceeded, the actuator member 35a approaches too close to the end stops 16 and 17, a predetermined limit speed is exceeded, or the like, the shift output device 53 switches the shift valves 50 to their locked positions.
  • a voltage sensor 59 and a current sensor 60 monitor the power supply 61 of the valve module 13a and the switching output device 53 generates the switching signal 54 on the basis of the sensor signals 74, 75 supplied by the sensors 60, 61, for example in the case of a current or voltage drop the switching valves 50 switches in blocking position.
  • a position sensor 62 of the valve module 13a detects the respective position of a valve member of the valve 38 and generates a position sensor signal 63 dependent on its position.
  • the control module 40 controls the position of the valve member on the basis of the position sensor signal 63.
  • the position sensor 62 also transmits the position sensor signal 63 to the switching output device 53. If, for example, the valve member jams or is braked by an obstacle in its movement, this is recognizable from the position sensor signal 63.
  • the switching output device 53 evaluates the position sensor signal 63 and thus recognizes, for example, a malfunction in the valve 38. In the event of a fault, the switching output device 53 switches the switching valves 50 into the blocking position via at least one switching output 52a.
  • the switching output 52a is a digital switching output.
