Definitions

  • the invention relates to a pressure cylinder arrangement with position sensors for position detection of the piston position with at least one analog position sensor, and with at least one pressure medium cylinder in which an axially guided piston is arranged, with which a piston rod is coaxially connected, which is provided by a gaskets Housing cover protrudes from the cylinder housing, and with at least one electromagnetic valve, which is connected to at least one signal line with at least one programming device, according to the preamble of claim 1.
  • the pressure-cylinder arrangement with position detection of the piston position in this example comprises a sensor and a mounting.
  • the attachment has a proximal end which abuts a cylinder tube to fix the position of the attachment.
  • the proximal end has a first attachment groove into which a pull rod is inserted, and first set screws for securing the inserted pull rod to the attachment.
  • a second attachment groove is formed, and the sensor can be mounted in this groove so that the position of the sensor in the axial direction of the cylinder tube is adjustable.
  • the attachment can be independently attached at the correct angle to the tie rod by: the attachment is attached to the pull rod while the tip portion of the attachment abuts the cylinder tube.
  • the sensor can be fixed in an independent manner to that on the pull rod, whereby the fastening operation is simplified.
  • the sensor can be independently installed or removed when replacing or adjusting its position without disengaging, thereby simplifying maintenance.
  • the sensor can be anchored at any position in the mounting groove using a second set screw.
  • the second set screw and the first set screws for attachment may be provided in the same direction so that they can be rotated from the same direction using a tool.
  • the attachment groove preferably has a cross-section that is shaped to be smaller than the groove width of the fastener groove but larger than the groove width of the hole while the groove has a groove width.
  • the object of the invention is therefore to provide a Sensoreingnasschwkeit without the need for access to the pressure cylinder arrangement.
  • the object is achieved in that the position sensor detects the stop position of the piston and a signal line to a programmer in turn, which in turn stores the current stop position of the piston in a non-volatile memory of the position sensor.
  • This solution has the advantage that the position detection of the piston position can be performed via a remote adjustment, which makes a direct access to the pressure cylinder arrangement superfluous and thus can be spared the complex removal and installation work of the pressure cylinder arrangement.
  • the size of the position sensor is kept quite small by the use of an EPROM, so that the overall size of the position detecting device is minimal.
  • a mobile position-SET module can also be used as an alternative to a stationary programming device-which is preferably a PLC (programmable logic controller).
  • a stationary programming device which is preferably a PLC (programmable logic controller).
  • the piston first moves to the desired position, after which this position is taken over by a button of the position-SET module.
  • the pressure medium cylinder arrangement with position sensors for the position detection of the piston position, inter alia, an analog position sensor 1, which contains a non-volatile memory 12 and is attached to a pressure medium cylinder 4, in which an axially guided piston 8 is arranged, on which a piston rod. 6 coaxially connected, which protrudes through a gasketed housing cover 5 from the cylinder housing, and is supplied with an electromagnetic valve with pressure energy. Both the position sensor 1 and the electromagnetic valve are connected via a signal line 9 to a programming device 3.
  • the pressure cylinder arrangement including the position sensor 1 and the electromagnetic valve 7 is installed in a machine. Whereby the pressure medium cylinder arrangement does not necessarily have to be accessible.
  • the programming device 3 embodied here as a PLC comprises an electrical power supply 31, a CPU 32, an input signal connection 33 and an output signal connection 34.
  • the signal line 9 connects the pressure medium cylinder arrangement and the electromagnetic valve 7 via two interfaces 10 and 11 to the programming device 3.
  • the piston 8 is moved by means of the electromagnetic valve 7 to a position which is detected by the position sensor 1 as a stop position. This position is then programmed by the programmer 3 as a current stop position in the non-volatile memory 12. Another, opposite stop position can be detected by a second position sensor 2 and programmed by the programmer 3 as the current, second stop position in the non-volatile memory 13.
  • the position sensor 1 operates analogously, whereas a digital data transmission takes place.
  • the signal line 9 is executed as a data bus in this respect.
  • the nonvolatile memory 12 may be implemented as an EPROM.
  • FIG. 2 differs from the previously described embodiment in that a mobile position-SET module 15 is used for the position programming instead of a stationary programmer.
  • the piston rod 6 is moved against a mechanical end stop 18.
  • An LED 16 of the position SET module 15 lights up.
  • a button 17 of the position-SET module 15 is actuated, so that the LED 16 lights up with a steady light.
  • the position of the piston 8 is stored in the position sensor 1 taking into account the tolerances via the position-SET module 15.
