Definitions
- the invention relates to a drainage medium cylinder arrangement with position sensors for the 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, to which a piston rod is coaxially connected, which is provided by a seal provided with seals 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 medium cylinder arrangement with position detection of the piston position in this example comprises a sensor and a fastening.
- the attachment has a proximal end that abuts a cylinder barrel to determine the position of the attachment.
- the proximal end has a first fastening groove, into which a pull rod is inserted, and first set screws for fastening the inserted pull rod to the fastening.
- a second fastening groove is formed in the tip section, and the sensor can be mounted in this groove in such a way that the position of the sensor can be adjusted in the axial direction of the cylinder tube.
- the attachment can be independently attached to the tie rod at the correct angle by attaching the attachment to the tie rod while the tip portion of the attachment is against the cylinder barrel. This allows the sensor to be fixed independently on the pull rod, which simplifies the fastening process. In addition, when replacing or adjusting its position, the sensor can be installed or removed independently without loosening the attachment, which simplifies 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.
- This configuration avoids work spaces in two directions, whereby the operations described above can be reliably performed even in small work spaces using the tool.
- the fastening groove preferably has a cross section which is shaped such that it is uter-wide, while the sensor has a width, is smaller than the inner outer width of the fastening device groove but larger than the outer width of the opening.
- a disadvantage of the known pressure medium cylinder arrangement is that access for the sensor setting during assembly must be taken into account.
- the object is achieved in that the position sensor detects the stop position of the piston and via a signal line to a programming device forwards, 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 carried out via a remote setting, which makes direct access to the pressure cylinder arrangement superfluous, and thus the time-consuming removal and installation work of the pressure medium cylinder arrangement can be spared.
- the size of the position sensor is kept quite small by the use of an EPROM, so that the overall size of the position detection 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).
- the piston first moves to the desired position, after which this position is adopted via a button on the Position SET module.
- FIG. 1 shows a schematic side view of a drainage medium cylinder arrangement with position sensors for the position detection of the piston position with remote adjustment with a signal line and a stationary programming device designed as a PLC
- Fig. 2 is a schematic side view of a Drackstoffylinderan Aunt with position sensors for position detection of the piston position with remote adjustment with a position SET module.
- Fig. 1 contains a drainage cylinder arrangement with position sensors for the position detection of the piston position, among others.
- an analog position sensor 1 which contains a non-volatile memory 12 and is attached to a middle cylinder 4, in which an axially guided piston 8 is arranged, to which a piston rod 6 is coaxially connected, which is provided with a housing cover 5 provided with seals from the cylinder housing protrudes, and is supplied with an electromagnetic valve with drain energy.
- Both the position sensor 1 and the electromagnetic valve are connected to a programming device 3 via a signal line 9.
- the drainage medium cylinder arrangement together with the position sensor 1 and the electromagnetic valve 7 is installed in a machine.
- the draining agent cylinder arrangement does not necessarily have to be accessible.
- the programming device 3 embodied here as a PLC consists of 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
- 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 programming device 3 into the non-volatile memory 12 as the current stop position.
- a further, opposite stop position can be detected by a second position sensor 2 and can be reprogrammed by the programming device 3 into the non-volatile memory 13 as the current, second stop position.
- the position sensor 1 works analogously, whereas one digital data transmission takes place.
- the signal line 9 is designed as a data bus.
- the non-volatile memory 12 can be implemented as an EPROM.
- the exemplary embodiment shown in FIG. 2 differs from the previously explained exemplary embodiment in that a mobile position SET module 15 is used for position programming instead of a stationary programming device.
- 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.
- PLC Programming device
