Definitions

  • the invention relates to a drive device with two units which can be driven relative to one another, functional units such as sensors or valves being provided on the first of the two units for controlling and / or monitoring the relative movement between the two units, which have signal conductors integrated into the first unit are connected to a node element fixed to the first structural unit.
  • functional units such as sensors or valves being provided on the first of the two units for controlling and / or monitoring the relative movement between the two units, which have signal conductors integrated into the first unit are connected to a node element fixed to the first structural unit.
  • Such a drive device is shown in the form of a fluid-driven piston-cylinder unit from DE 39 23 063 C2.
  • the first structural unit formed by a multi-part housing has a longitudinal groove in which sensors can be anchored.
  • the sensor signals are routed via signal conductors integrated in the sensor groove in the form of conductor tracks to a node element plugged into the end, to which further electrical lines can be connected, which are connected to a Control device are connected.
  • valves are integrated in the housing, which control the application of fluid to the piston of the piston-cylinder unit which forms the second structural unit, and which also lead via signal conductors in the housing to the node element, which in the concrete case is plate-shaped.
  • the signals supplied by the sensors are processed in the control device, which then sends the necessary actuation signals to the valves.
  • a considerable wiring effort is therefore required.
  • the installation of a device which contains several of the piston-cylinder units described therefore requires a relatively large outlay and provides a large number of possible later sources of error in the operating sequence.
  • the node element contains central signal processing electronics for the signals coming from the functional units and the signals to be transmitted to the functional units.
  • the signal processing electronics integrated in the node element are designed as control electronics, which contain a preferably freely programmable control program and which directly takes over the control and monitoring of the drive device.
  • the intelligence of the control is thus integrated into the drive device itself and controls, for example, depending on the sensor signals received, the actuation of likewise integrated valves which, in the case of a fluid-operated drive device, control the pressurization of the second structural unit.
  • the signal processing electronics of the node element are designed as fieldbus communication electronics, which are connected via a serial fieldbus with a small number of wires to an external control device and forwards the control signals received by the latter to the relevant functional units with the correct assignment.
  • the electronics can be a so-called ASI (Actor Sensor Interface) or a so-called LON (Local Operating Network).
  • the subclaims contain advantageous configurations of the drive device.
  • the node module can be a plug-in module, for example. It comprises a first set of contact elements which, when mounted on the first structural unit, wire simultaneously in connection with a second set of contact elements on the first structural unit, these contact elements being readily formed by signal conductors, for example conductor tracks. With the assembly of the node module, all connections relevant for signal transmission are expediently established at the same time, so that the connection effort is minimal.
  • An expedient embodiment provides that there is a multiple arrangement of signal conductors on the first structural unit, which extends from the node element over the length of the first structural unit. This multiple arrangement of signal conductors can then be tapped or tapped at practically any point in order to make the signal connection to functional units arranged on the first structural unit at a suitable point.
  • Such a multiple arrangement of signal conductors could, for example, consist of a multi-core ribbon cable which is installed in an anchoring groove extending along the first structural unit, the installation also being able to be carried out by the user, depending on the design.
  • the sensor in order to connect a sensor to be fixed in the anchoring groove to the assigned signal conductors, the sensor can have lancing elements that pierce or press into the signal conductors when the sensor is fastened, thereby establishing the signal connection.
  • a two-wire line is expediently sufficient, via which the required continuous operating voltage is supplied (for example 24 volts) and via which signals can also be transmitted, if required, which are superimposed on the voltage signal.
  • all functional units provided on the drive device can + be connected centrally to the node element, which thus represents the only interface to the outside and makes the practical installation of the drive device relatively simple, even for non-specialists.
  • the exemplary embodiment shows a drive device 1 which is designed as a linear drive 2 and has two structural units 3, 4 which can be moved in relation to one another in translation. It is expediently a fluid-actuated linear drive, the first structural unit 3 being formed by a housing 5 and the second structural unit 4 being formed by an output part 6 which can be driven in relation to the housing 5.
  • the housing 5 contains one from FIG. 2 partially visible and preferably cylindrically contoured chamber 7, in which a piston 8 is arranged such that it can be moved linearly and is connected to a piston rod 12 which protrudes from the front of the housing 5.
  • the piston 8 and the piston rod 12 represent the driven part 6.

  • An object to be moved can be attached to the outer end of the piston rod 12.
  • the linear drive 2 can also be an electrical linear drive, furthermore the linear drive can be designed without a piston rod, the output part 6 being connected in another way to a component which is longitudinally displaceable on the outside of the housing and is suitable for power take-off.
  • This can be a so-called slot cylinder or a band cylinder, or a rodless cylinder with magnetic coupling between the piston and the outer component.
  • a plurality of functional units 17 are arranged on the housing 5 of the linear drive 2, which are used to control and monitor the Relative movement between the two units 3, 4 serve.

  • a functional unit 17 shown in FIG. 3 in addition to FIG. 1 is a position detection device 23 which, for example, enables a constant determination of the current piston position in an analog way. It extends along the piston stroke and can be based on an ultrasound working principle in which the duration of a sound wave in a magnetostrictive body is evaluated.
  • valves 24 which can be designed as proportional valves or as switching valves and expediently have an electromagnet 25 which is schematically indicated in FIG. 2 and which functions as an actuating unit for the valve member.
  • the valves 24 according to the example are configured in the manner of cartridges and, in particular, are completely embedded in a housing-side cavity 26, so that there are no disruptively protruding parts. These valves 24 are switched into the fluid channels inside the housing which are connected to the connection openings 15 and lead into the two working spaces of the linear drive 2. A fluid supply or discharge with respect to the connected work space can be controlled in accordance with the respective actuation of the valves 24.
  • a node element 27 is provided in the area of the rear end of the housing 5. It is in signal connection with all of the functional units 17 via signal conductors 28 integrated in the housing 5. These signal conductors 28 are indicated by dashed lines in FIGS. 1 and 4, and are shown in solid lines in FIGS. 2 and 3. The designation node element was chosen because all signal conductors 28 converge centrally in this component. In this way, all of the monitoring signals supplied by the sensors 18 and the possibly present position detection device 23 are fed to the node element 27. Likewise, the valves 24 and other functional units 17 dependent on control signals receive their corresponding control signals from the node element 27.
