Definitions
- the invention relates to a method and an apparatus for filling a fluid into a pressure tank.
- Such methods and devices are, for example, in systems for the coating of substrates, such as. B. CDs known.
- a varnish in a pressure tank is moved to a coating station by the pressure in the pressure tank via a riser.
- the paint is applied to the CDs to be coated via an outlet valve. It is important for a uniform and continuous coating of the CDs that the pressure of the paint to be provided at the outlet valve has as constant a predetermined value as possible.
- the object of the invention is therefore to enable the filling of a fluid into a pressure tank without the need to interrupt the use of the pressure tank.
- the object is achieved according to the invention by a method for filling a fluid into a pressure tank from a higher refill tank, which are connected to one another via a gas connecting line and a fluid filling line, by regulating the pressure in the pressure tank via a gas Proportional valve located in the inlet line of the pressure tank while the connecting lines to the refill tank are closed, regulating the pressure in the refill tank to the pressure in the pressure tank and opening the connecting lines between the refill tank and pressure tank.
- the pressure conditions within the pressure tank are not changed by the filling process, since the pressure in both tanks is the same, so that the function and use of the pressure tank are not impaired.
- the fact that the refill tank is higher than the pressure tank creates a hydrostatic pressure difference which leads to the fluid running into the pressure tank without changing the gas pressure within the pressure tank.
- the gas inlet line between the proportional valve and the pressure tank is closed before the pressure in the refill tank is regulated, and the pressure in the refill tank is regulated via the same proportional valve that is used for regulating the pressure in the pressure tank .
- This has the advantage that the same components are used for regulating the pressure in the refill tank as for regulating the pressure in the pressure tank, without adversely affecting the pressure in the pressure tank. It is not possible to readjust the pressure in the pressure tank while the pressure in the refill tank is being adjusted, but a significant pressure change within the pressure tank that limits the function of the pressure tank takes longer than the adjustment of the pressure in the refill tank to the pressure in the pressure tank.
- the gas inlet line can be opened again so that the system is not affected by the short-term closing.
- the pressure in the pressure tank is regulated to a pressure setpoint, which is determined as a function of measurement results of a first pressure sensor arranged in an outlet line of the pressure tank, in order to automatically adapt the system to changing disturbance variables, such as the filling level of the fluid in the To achieve tank and filter pressure losses of a filter typically located in the outlet line.
- the pressure setpoint is advantageously not changed as long as the gas inlet line between the proportional valve and the pressure tank is closed, since readjustment of the pressure in the pressure tank is not possible at this point in time, and a change in the pressure setpoint would result in the refill tank would be set to a different pressure than the pressure tank. This would lead to undesirable pressure changes when opening the connecting lines between the refill tank and the pressure tank.
- the pressure in the gas inlet line is advantageously measured in order to provide the actual pressure required for regulating the pressure in the pressure tank or the pressure in the refill tank.
- the measurement of the actual pressure in the gas inlet line has the advantage that the same pressure sensor is used for the pressure tank and the refill tank, as a result of which higher accuracy can be achieved and costs for an additional pressure sensor are saved.
- no dynamic line and / or filter pressure losses occur in the gas inlet line, so that a stable control behavior of the proportional valve is achieved without vibrations.
- the pressure setpoint is determined as a function of a differential pressure sensor which is arranged between the gas inlet line and the outlet line of the pressure tank, as long as the connecting lines between the refill tank and the pressure tank are open.
- a differential pressure sensor between the gas inlet line and the outlet line of the pressure tank, the filling level that changes during filling can be taken into account and the pressure setpoint can be compensated accordingly.
- the use of a differential pressure sensor enables an automatic display of when the filling process has ended.
- the object on which the invention is based is also achieved by a device for filling a fluid into a pressure tank from a higher-level refill tank, which are connected to one another via a gas inlet line and a fluid filling line, in which the device has a proportional valve in the gas inlet line for introducing a pressurized gas into the pressure tank, a first valve which is arranged between the proportional valve and the pressure tank, a second valve which is arranged between the proportional valve and the refill tank, and a third Valve, which is arranged in the fluid filling line.
- the above device in turn enables the pressure within a refill tank to be brought to the same pressure as the pressure in the pressure tank without influencing the pressure in the pressure tank. A connection can then be established between the refill tank and the pressure tank, so that the fluid in a refill tank flows into the pressure tank due to a hydrostatic pressure difference without changing the gas pressure conditions in the pressure tank.
- a first pressure sensor is preferably provided in an outlet line of the pressure tank and is connected to a control unit which determines a pressure setpoint for the proportional valve based on the measurement results of the first pressure sensor. As already explained above, this enables the system to be adapted to variable disturbance variables, such as tank level and filter pressure losses.
- the device preferably has a second pressure sensor which is arranged in the gas inlet line in order to provide an actual pressure value for regulating the proportional valve which is not influenced by dynamic line and filter pressure losses.
- the device has a differential pressure sensor between the gas inlet line and the outlet line in order to during the filling of the Fluids in the pressure tank to allow automatic adjustment of the system parameters to the changing tank level.
- the refill tank can be connected to the gas inlet line and the fluid refill line via coupling elements.
- This enables the refill tank to be filled remotely from the pressure tank, and the refill tank can also be used for the sequential filling of several pressure tanks.
- the coupling elements advantageously have sensors that provide an automatic display of when the coupling elements are closed.
- the second and third valves can be automatically closed by loosening the coupling elements so as not to impair the system of the pressure tank if the coupling elements are incorrectly released.
- the coupling elements are preferably quick couplings.
- Figure 1 shows an inventive device for filling a fluid in a pressure tank.
- 2 shows an alternative form of the device for filling a fluid into a pressure tank;
- 3 shows a flow diagram for the sequence of a refilling process.
- Figure 1 shows a coating system 1 for CDs.
- the coating system 1 has a pressure tank 4 with a gas inlet line 5, an outlet line 6 and a fluid filling line 7.
- the gas inlet line opens to an upper region of the pressure tank 4, while the outlet line 6 and the fluid filling line 7 extend into a lower region of the pressure tank and are open to the latter.
- the pressure tank 4 is partially filled with a lacquer 8 for lacquering the CDs. Due to the weight of the paint 8, it fills a lower area of the pressure tank 4. In the area above the paint there is a pressurized gas 10, such as nitrogen.
- the nitrogen 10 is filled into the pressure tank 4 by a nitrogen supply 12 which is connected to the inlet line 5.
- a nitrogen supply 12 which is connected to the inlet line 5.
- a valve unit 14 with a proportional valve 15 and an internal pressure sensor 16, which is arranged between the proportional valve 15 and the pressure tank 4.
- valve 17 is provided in the gas inlet line 5 for closing or opening the gas inlet line.
- a differential pressure sensor 18, which is able to measure the pressure difference between the two lines, is provided between the inlet line 5 and the outlet line 6, adjacent to the upper side of the pressure tank 4.
- a filter 22 and a pressure sensor 24 connected to the outlet line 6 and an outlet valve 26 are arranged in the outlet line 6 from the pressure tank 4 behind the differential pressure sensor 18. After the valve 26 (seen from the pressure tank 4), the outlet line 6 opens to a coating station 28, in which the lacquer 8 is applied to the CDs when the valve 26 is open.
- a further valve 30 is provided in the gas inlet line 5, which is designed as a one / two-way valve and which is not located on a direct connection between the valve unit 14 and the pressure tank 4. Rather, the valve 30 is located in a part of the gas inlet line 5, which ends in a coupling element of a quick coupling 32.
- the valve 30 is capable of having either the coupling end of the gas inlet line 5 to connect the valve unit, or to close this connection and to connect the coupling end of the gas inlet line 5 to the atmosphere.
- a connecting line 35 to the gas A ⁇ laß Arthur coupled is connected to a replenishing tank 36 in connection.
- the refill tank 36 is filled with paint 8 and can be pressurized with gas under pressure via the gas inlet line 5 and the connecting line 35, the connecting line 35 opening into an upper region of the refill tank 36.
- the pressure tank 36 is located on a trolley 38 and can be transported with it.
- the refill tank 36 is higher than the pressure tank 4.
- the refill tank 36 has a fluid outlet line 40 which ends in a coupling element of a quick coupling 42 and can be connected via the quick coupling 42 to an end of the fluid filling line 7 remote from the pressure tank 4. Between the quick coupling 42 and the pressure tank 4, a valve 44 for opening and closing the fluid filling line is provided in the fluid filling line 7.
- the coating system has a control unit 45 which is connected to and communicates with different components of the coating system.
- a number of blocks denoted by SW are provided in FIG. 1, each of which represents the control unit 45.
- the trolley 38 can be electrically connected to the control unit 45 via a quick coupling 47 in order to provide an indication of when the refill tank is properly coupled to the coating system 1.
- An input terminal 48 for the control unit 45 is provided, for example in order to be able to input a pressure setpoint into the system.
- the control unit 45 is connected to the internal pressure sensor 16 of the valve unit 14 and receives from it the pressure pi n t measured in the gas inlet line 5. From the differential pressure sensor 18, the control unit 45 receives a differential pressure value ⁇ p based on the measured pressure difference between the gas inlet line 5 and the outlet line 6. From the pressure sensor 24, the control unit 45 receives a pressure value p ex t measured in the outlet line 6.
- the control unit 45 determines a corrected pressure setpoint Psoi orr, which it forwards to the proportional valve 15 of the valve unit 14 for regulating the pressure in the gas inlet line 5.
- the pressure pj nt measured in the gas inlet line 5 is also forwarded by the pressure sensor 16 as the actual pressure to the proportional valve 15 for the regulation thereof.
- the control unit 45 controls the opening and closing of the valves 17, 26, 30 and 44 via suitable connections.
- Figure 2 also shows schematically a coating system 1 for CDs.
- the same reference numerals are used in FIG. 2 as in FIG. 1 to denote identical or equivalent components.
- valves 50, 51 are used in the system in FIG can be switched alternately to connect the coupling end part of the gas inlet line 5 to the rest of the gas inlet line 5 via the valve 50 or to vent to the atmosphere via the valve 51.
- the control unit 45 has an input part 45, into which pressure values of the internal pressure sensor 16, the differential pressure sensor 18 and the pressure sensor 24 are fed.
- the control unit 45 also has a processor unit 55 in which different control parameters are calculated.
- the control unit 45 controls the opening and closing of the different valves 17, 26, 44, 50 and 51 via an output unit 56.
- a pressure setpoint p S oi ⁇ , corr is specified via the control unit 56 of the valve unit 14, in particular the proportional valve 15, which is determined on the basis of the supplied pressure values of the internal pressure sensor 16, the differential pressure sensor 18 and the pressure sensor 24.
- valve 44 is closed and valve 30 is open to the atmosphere, or valve 50 is closed and valve 51 is open.
- the refill tank is not connected to the coating system 1.
- the valve 17 is opened and the CDs in the coating station 28 are lacquered by opening and closing the valve 26, the lacquer in the pressure tank 4 being pressed to the lacquering station 28 by the pressure in the pressure tank 4.
- a refill tank 36 filled with lacquer 8 is placed in block 62 via the quick coupling gene 32, 42 connected to the ends of the gas inlet line 5 and the fluid filling line 7.
- the quick couplings 32, 42 are provided with capacitive sensors in order to immediately provide an indication and, if necessary, to provide for the valves 30 or 50 and 44 to be closed if the quick couplings are incorrectly uncoupled.
- the valve 17 is then closed in a block 64, so that the pressure tank 4 is insulated from the valve unit 14.
- the determination of the corrected pressure setpoint Psoi orr is interrupted within the control unit 45 and the input terminal 48 is blocked in order to prevent an input of a changed pressure setpoint.
- the pressure in the pressure tank 4 is maintained despite the gas supply being interrupted, without readjustment being possible at this point in time.
- the lacquering processes of CDs in the lacquering station 28 are nevertheless continued, since the pressure in the pressure tank only drops after approximately fifty dispensing cycles in such a way that readjustment would be necessary.
- valve 30 or valve 50 is opened and valve 51 is closed in order to provide a connection between valve unit 14 and refill tank 36 via gas inlet line 5 and connecting line 35.
- the pressure in the refill tank 36 is then regulated to the last pressure setpoint p SO ⁇ , k orr determined before the valve 17 was closed.
- the valve 44 in the fluid filling line 7 is then opened in block 70. Due to the hydrostatic pressure difference between the paint 8 in Refill tank 36 and the paint 8 in the pressure tank 4, the paint flows from the refill tank 36 into the pressure tank 4. Due to the changing filling level of the paint 8 in the pressure tank 4, the corrected pressure setpoint during this phase only depends on the measurement results of the difference - Pressure sensor 18 determined because this provides a sensitive display for the changing tank level. The system can thus be adapted to the changing tank fill level.
- the end of the filling process is determined on the basis of the measurement results from the differential pressure sensor 18.
- the end of the filling process is recognized if the following equation is fulfilled:
- the valve 44 is kept open further in block 74 and the corrected pressure setpoint Psoii.korr is further adjusted via the differential pressure ⁇ p. This state is maintained as long as the end of the tank is not reached. If the end of the tank filling is not reached within a certain period of time that is longer than a normal time period for a filling process, the system can emit a warning signal, whereby an error when filling the pressure tank 4 is indicated.
- valve 44 is closed in a block 76.
- valve 17 is first closed and then either one-way / two-way valve 30 (according to FIG. 1) is set to vent or (according to FIG. 2) valve 50 is closed and valve 51 is opened.
- the valve 17 should be closed during this changeover to avoid any pressure surges within the Isolate gas inlet line 5 from the pressure tank. If necessary, the pressure within the gas inlet line 5 must be readjusted after the changeover of the valve 30 or the valves 50 and 51. Subsequently, the valve 17 is opened again, and the control unit 45 returns to the normal determination of the corrected setpoint p S oi ⁇ , k orr.
- the control unit 45 then goes back to the normal determination of the corrected pressure setpoint p S oi ⁇ , corr.
