Definitions

  • the invention relates to a control device for fluidic media, in particular for compressed air, with base plate modules which can be arranged in a row, the first fluid channels of which run flush in the longitudinal direction of the row, close to one another, and also with an electromagnetic valve assigned to each base plate module, the second fluid channels of which can be shut off or released in a controlled manner and open into the first fluid channels. also with protective contact conductors, neutral conductors and signal conductors connected to each electromagnet, of which the protective contact conductor and the neutral conductor are looped through in the longitudinal direction of the row and the signal conductor connects the electromagnetic valve to the respective output of a signal source.
  • Control devices influencing such fluid flows use electromagnetic valves, on the solenoid coil of which three contacts are required in each case: a protective contact conductor for the electrical potential of the neutral conductors, and a protective conductor connection a signal conductor for the transmission of the control command.
  • each of these solenoid valves must be connected to the three conductors.
  • the protective contact conductor and the neutral conductor are looped through from the first to the last module and removed directly when a valve is attached. Since the solenoid valves arranged in series are usually not to be switched simultaneously, each individual solenoid valve must be connected to the respective output of the signal source.
  • a device for controlling machines is known (DE-C2-30 42 205) with switching modules, which are composed of a peumatic valve and an electric drive for the valve, the valve being detachably connected to a pneumatic distributor bar and an electrical control module for the drive.
  • the electrical control module is electrically connected to the electromagnet on the one hand via a multiple plug and, on the other hand, to an electrical distribution rail via a further multiple plug.
  • direct assignment of a control module to the distribution rail is not possible and desirable in all cases.
  • the base plate module is therefore designed to be considerably complicated and the entire device is very complex.
  • the present invention has for its object to further develop the known module system with simple means with the aim of being able to switch a larger number of base plate modules which can be arranged in such a way that on the one hand individual base plate modules can be supplied with individual signals and on the other hand also several base plate modules the same signal at the same time.
  • each base plate module is assigned a plug base for the protective contact conductor, neutral conductor and signal conductor, and that a plurality of signal conductors from the first to the last base plate module are arranged in parallel in an electrically non-conductive bearing plate adjacent to the looped-through protective contact conductor and the neutral conductor are that there is an electrically conductive signal connection plate above the bearing plate and that an electrical connection to the plug base can be switched from each signal connection plate.
  • a control device allows simple means to either individually control a selected solenoid valve or to supply any division of several solenoid valves together and simultaneously with the signal.
  • An improved embodiment provides that groups of contact openings associated with a looped-through insulated signal conductor are provided in the signal connection plate, the signal conductor being conductive within a selected contact opening and that the connection to the electromagnet can be switched by means of a contact plug.
  • the contact plugs are used not only to transmit the electrical signal, but also to identify the circuit configuration.
  • the base plate module and the non-conductive bearing plate formed for the insulation of the signal connection plate are accommodated in a common housing.
  • the compactness and a correspondingly low space requirement for the control device are achieved.
  • the base plate module also serves as a fastening for the signal connection plate and for the bearing plate. This solution practically results in a uniform housing for the base plate module, plug base, bearing plate, signal connection plate and the corresponding conductors.
  • Each base plate module 1 is assigned an electromagnetic valve 2, consisting of a pneumatic valve 2a and a connected electromagnet 2b.
  • the base plate modules 1 have first fluid channels 3 and 4 running in the direction of the row of four units. In each case two base plate modules 1 are joined to one another in a sealed manner on the fluid channels 3 and 4. From the valve 2a, second fluid channels 5a and 5b open into the first fluid channels 3 and 4.
  • a protective contact conductor 7, neutral conductor 6 and a signal conductor 8a are arranged on each solenoid valve 2 or on the electromagnets 2b.
  • the four drawn electromagnetic valves 2 form a row, and the looped protective contact conductors 7 and neutral conductors 6 run perpendicular to a longitudinal axis 9 of an electromagnet 2b.
  • the longitudinal direction 10 is therefore perpendicular to the direction of the longitudinal axis 9.
  • Each base plate module 1 lined up on a rail, not shown has a plug base 11 for the protective contact conductor 7 or the protective contact conductor 7a, the neutral conductor 6 or the neutral conductor 6a.
  • a plug opening 8b is incorporated in the connector base 11 for the signal conductor 8a.
  • the protective contact conductor 7 and the neutral conductor 6 each have receiving slots 12.
  • a multiplicity of signal conductors 8 are looped through from the first to the last base plate module 1 parallel to the longitudinal direction 10 below an electrically conductive signal connection plate 13 and within a bearing plate 13a.
  • the looped-through signal conductors 8 are generally insulated from the electrically conductive signal connection plate 13, or a conductive electrical connection is created only at very specific points (for example by means of a dip switch), so that the electrical signal coming from the output of the signal source is applied to the plug base 11 is switchable.
  • the electrically conductive connection can therefore already be created during its manufacture by appropriately designing the signal connection plate 13 on the inside, e.g. through dip switch. From the signal connection plate 13, a connection via the plug opening 8b to the signal conductor 8a is created via a conductor 13b.
  • Groups 15 of at least two contact openings 16 are provided in the signal connection plate 13.
  • the signal conductor 8 is contacted within a selected contact opening 16, either in an upper or in a lower level.
  • a contact plug 17 inserted into a contact opening 16 switches the electrical connection.
  • Contact openings not required 16 can also be closed with insulated contact plugs or with smaller lids.
  • the elastic layer can also act as a separating layer against moisture.
  • the base plate module 1 is continued in the plug base 11 and, moreover, a non-conductive bearing plate 13a formed for the insulation of the signal connection plate 13 is arranged in a common housing 18 (FIG. 1).
  • the bearing plate 13a can already be made in one piece with a housing 18.
  • the bearing plate 13a naturally has the contact openings 16 that match the signal connection plate 13.
  • the base plate module 1 with its housing 18 also serves as a fastening for the signal connection plate 13.
