Definitions
- the invention relates to a paint supply system for a coating installation, in particular for a painting installation for painting motor vehicle body components. Furthermore, the invention relates to an operating method for such a paint supply system.
- the paint is usually fed through ring lines to the consumers (e.g. rotary atomizers), with the paint circulating in the ring lines so that the paint does not settle.
- the consumers e.g. rotary atomizers
- the problem here is the fact that the paint does circulate in the ring line, but not in the branch line. So if a consumer (e.g. rotary atomizer) is not used for a longer period of time, the paint is in the associated branch line, which can lead to the paint settling or its viscosity changing in the event of a longer standstill.
- a known solution to this problem is to automatically empty the stub lines after a certain period of standstill, which is also referred to as unplugging.
- the paint in the branch line is disposed of in a return line.
- this known solution to the problem is disadvantageous because it is associated with paint losses and additional effort.
- Another conceivable solution to this problem is to continue the material circulation into the consumer (e.g. rotary atomizer) so that a branch line can be dispensed with entirely.
- This conceivable solution requires two circulation lines for outgoing and return lines instead of a single stub line and is therefore much more complex.
- this requires twice the number of paint hoses up to the color changer, so that the number of possible paint feed lines is reduced due to the limited installation space.
- the invention is therefore based on the object of creating a correspondingly improved paint supply system and an associated operating method.
- the paint supply system according to the invention is used to supply a coating system with a coating agent, which is preferably a paint that is used for painting motor vehicle body components.
- a coating agent which is preferably a paint that is used for painting motor vehicle body components.
- the invention is not limited to paints, but can also be implemented with other types of coating agents.
- the invention with regard to the type of coating system is not limited to painting systems for painting motor vehicle body parts. Rather, the paint supply system according to the invention can also be used to supply coating systems that coat other types of components.
- the paint supply system according to the invention also has at least one ring line for the circulation of a coating agent (e.g. paint).
- a coating agent e.g. paint
- Such ring line systems are known per se from the prior art and are described, for example, in Pavel Svejda: “Processes and application methods in industrial painting technology", Vincentz-Verlag 2003. It should be mentioned here that in practice several ring lines are usually provided in In the following, however, for the sake of simplicity, mostly only the removal of the coating agent from a single ring line is described. It goes without saying, however, that the coating agent is generally removed from several ring lines.
- the removal of the coating agent from the ring main takes place at a ring main extraction point that is connected to a consumer (eg rotary atomizer) via a branch line.
- a consumer eg rotary atomizer
- the invention is not limited to atomizers (for example rotary atomizers) with regard to the consumer.
- the consumer can also be another component or assembly that requires the coating agent.
- the paint supply system has a device which moves the coating agent in the stub line alternately forwards and backwards in order to avoid the deposition of the coating agent in the stub line.
- This forward and backward movement of the coating agent in the branch line can take place differently in different variants of the invention.
- a first variant of the invention is first described, which for this purpose initiates pressure surges via the ring line into the stub line, which are reflected in the stub line, which leads to the forward and backward movement of the coating agent in the stub line.
- the consumer e.g. rotary atomizer
- a compressible medium e.g. air cushion
- the pressure surges in the branch line are generated by a pressure generator (e.g. coating agent pump) which pumps the coating agent through the ring line.
- a pressure generator e.g. coating agent pump
- This pressure generator is then activated by a control unit in such a way that the pressure in the branch line fluctuates jerkily. This can be done, for example, by alternately switching the pressure generator (e.g. coating agent pump) on and off.
- pressure surges are initially generated in the ring line, which then spread over the stub line and are reflected at the end of the stub line, which then leads to the forward and backward movement of the coating agent in the stub line.
- the desired reflection of the pressure surges at the end of the branch line is preferably carried out by a cushion of a compressible medium (for example air cushion) at the end of the branch line, the cushion preferably has a volume which is 10% -150%, 20% -130% or 30% -110% of the volume of the stub line.
- a cushion of a compressible medium for example air cushion
- the cushion can also be dispensed with within the scope of the invention.
- the coating agent column in the branch line together with the elastic cushion at the end of the branch line, forms an oscillatory system that has a specific natural frequency.
- the vibration excitation by the pressure generator then takes place preferably at the natural frequency or at least close to the natural frequency of this system capable of vibrations in order to move the coating agent column in the branch line as intensively as possible forwards and backwards.
- the pressure generator e.g. coating agent pump
- this switching on or off is preferably carried out at a switching frequency that corresponds to the natural frequency of the oscillatory system that is generated by the coating agent column in the branch line and the Pad is formed at the end of the branch line.
- the deviation between the excitation frequency of the vibration excitation by the pressure generator (e.g. coating agent pump) on the one hand and the natural frequency of the vibratory system consisting of the coating agent column in the branch line and the cushion at the end of the branch line on the other hand can be less than 20%, 10%, 5% or 2 %.
- the branch line opens into a valve arrangement which, on the output side, is connected to the consumer (e.g. rotary atomizer) and to a reservoir.
- the valve arrangement In a first operating mode, the valve arrangement then directs the coating agent supplied via the branch line to the consumer, so that the consumer can apply the coating agent, for example.
- the valve arrangement In a second operating mode, on the other hand, the valve arrangement alternately directs the coating agent from the stub line into the reservoir or from the reservoir back into the stub line. It is thereby achieved that the coating agent in the branch line is alternately moved forwards and backwards.
- the reservoir has a pig line which contains a displaceable pig and leads from the valve arrangement to a pig station.
- the return of the coating agent from the reservoir back into the branch line can take place here by a pig, which pushes the coating agent back into the stub line, in that the pig is pushed from the pig station in the direction of the valve arrangement.
- pigs and pig stations are known per se from the prior art and therefore do not need to be described in more detail.
- the pig line can have a pig station on both sides, so that the movement of the coating agent is driven by pigs in both directions.
- the pig line has a pig station only at its distal end. In this case, only the return of the coating agent from the pig line into the branch line is driven by a pig.
- the proximal pig station is connected to the valve arrangement via a connecting line. It is advantageous here if the connecting line has a smaller line cross-section than the pig line.
- two or more pig lines can also be connected to the valve arrangement, each of which forms a reservoir and each leads to a pig station.
- the old coating agent in the branch line can then first be transferred to the first pig line.
- the second pig line is then filled with fresh coating agent from the ring line.
- the old coating agent transferred into the first pig line is pushed back into the branch line and then into the Ringlei device.
- the fresh coating agent transferred into the second pig line is then pressed back into the branch line.
- the coating agent in the branch line is not only moved, but is completely or at least partially replaced with fresh coating agent from the ring line.
- valve arrangement can have a color changer (for example linear color changer) which is connected on the input side via a branch line to several ring lines for different coating agents.
- a color changer for example linear color changer
- coating agents with different colors usually circulate in the various ring lines, the color changer then being able to select the desired color on the input side, which is well known per se from the prior art.
- a linear color changer is known from DE 10 2008015 258 A1.
- the valve arrangement here preferably has a coating agent outlet which is connected to the consumer.
- valve arrangement can have a pulsed air inlet and a rinsing agent inlet in order to supply pulsed air or rinsing agent, wherein the supply can be controlled by a controllable pulsed air valve or by a controllable rinsing agent valve.
- valve arrangement can have a return connection in order to return media (e.g. coating agents, flushing agents) to a return, the material flow in the return being controlled by a controllable return valve.
- return media e.g. coating agents, flushing agents
- valve arrangement can have a reservoir connection which is connected to the above-mentioned reservoir (e.g. pig line).
- the material flow through the reservoir connection into the reservoir and back can be controlled by a controllable reservoir valve.
- valve arrangement can have selector valves in order to optionally pass the flushing agent and the pulsed air on through the reservoir connection into the reservoir, through the return connection into the return or through the coating agent outlet to the consumer.
- the consumer is preferably an atomizer (e.g. rotary atomizer) which can be moved, for example, by a multi-axis painting robot, as is known per se from the prior art.
- Painting robots of this type are usually designed as articulated arm robots with a proximal robot arm and a distal robot arm.
- the valve arrangement mentioned above can be attached in or on the proximal robot arm or in the distal robot arm.
- the aforementioned reservoir e.g. pig line
- a sufficiently large volume which is preferably 10% -150%, 20% -130% or 30% -110% of the volume of the branch line.
- a metering pump can be arranged between the valve arrangement mentioned above and the consumer (eg rotary atomizer). It should also be mentioned that the invention not only claims protection for the paint supply system according to the invention described above. Rather, the invention also claims protection for a paint shop with such a paint supply system, wherein the paint shop can be used, for example, to paint motor vehicle body components.
- the invention therefore also includes a control unit which controls the components of the paint supply system according to the invention (e.g. paint pump, return valve of the ring line, color changer valves) in such a way that the operating method according to the invention is carried out.
- the control unit can have a control computer on which a control program is stored which executes the operating method according to the invention.
- Figure 1 is a schematic representation of a paint supply system according to the invention according to a first variant of the invention
- FIG. 2 shows a schematic representation of a paint supply system according to the invention according to a second variant of the invention
- Figure 3A is a schematic representation of a further paint supply system according to the invention according to the second variant of the invention.
- FIG. 3B shows a detailed representation of the valve arrangement of the paint supply system according to FIG. 3A, as well as
- FIG. 4 shows the operating method according to the invention in the form of a flow chart.
- the exemplary embodiment according to FIG. 1, which corresponds to a first variant of the invention, will now first be described below.
- This paint supply system initially has a paint container 1 which is filled with paint 2 in a conventional manner.
- the paint 2 is removed from the paint container 1 by a paint pump 3 and pumped through a ring line 4, which is well known per se from the prior art.
- the paint pump 3 is controlled by a control unit 5, the control line 5 varying the delivery rate of the paint pump 3 and being able to switch the paint pump 3 on and off.
- the ring line 5 then opens again into the paint container 1, with a controllable return valve 6 being arranged at the end of the ring line 4, which is controlled by a control unit 7.
- the two control units 5 and 7 can be designed separately or be part of a common control system.
- a conventional counterpressure valve can be provided that sets a constant coating agent pressure in the ring line 4 upstream of the counterpressure valve, which is also well known from the prior art.
- An example of such a ring line system with a counterpressure regulator is known from US Pat. No. 7,828,527 B2.
- the drawing shows a rotary atomizer 8, which is only shown schematically here and removes the paint to be applied via a branch line 9 at a ring line extraction point 10 from the ring line 4.
- the application of paint by the rotary atomizer is controlled by a main valve 11, which is only shown schematically.
- the branch line 9 is led through the rotary atomizer 8, the rotary atomizer 8 taking the paint to be applied from the branch line 9 at a branch line removal point 12.
- branch line 9 is closed at its end and contains an air cushion 13 there, which is used to reflect pressure surges, as will be described below.
- the control unit 5 controls the paint pump 3 in such a way that the paint pump 3 is alternately switched on and off. This initially generates pressure surges in the ring line 4, which then propagate via the branch line 9 to the end of the branch line 9, where the pressure surges are then reflected on the elastic air cushion 13. This has the consequence that the standing paint in the branch line 9 is alternately moved forwards and backwards.
- the paint supply system with the paint column in the branch line 9 and the elastic air cushion 13 forms a system that can vibrate.
- the excitation frequency of the pressure surges should be adapted to the natural frequency of the oscillating system.
- the control unit 5 controls the paint pump 3 with a corresponding excitation frequency.
- FIG. 2 A second variant of the invention, which is shown in FIG. 2, is now described below.
- this variant of the invention partially corresponds to the first variant of the invention described above.
- This second variant of the invention is initially characterized by a color changer 14, which has a plurality of color valves F1-Fn on the inlet side, each of which is connected to a ring line.
- a color changer 14 which has a plurality of color valves F1-Fn on the inlet side, each of which is connected to a ring line.
- the ring line 4 is shown here, which is connected to the color valve F1 of the color changer 14 via the branch line 9.
- the other color valves F2-Fn of the color changer 14 are each connected via a branch line, not shown, to a respective ring line, not shown.
- the color changer has a coating agent outlet 15 to which the rotary atomizer 8 is connected.
- the color changer 14 also has a detergent connection 16 for supplying detergent, the detergent supply via the detergent connection 16 through a detergent valve V in the color changer 14 is controlled.
- the color changer 14 also has a pulsed air connection 17 for supplying pulsed air, where the pulsed air supply via the pulsed air connection 17 is controlled by a pulsed air valve PLI in the color changer 14.
- the color changer 14 also has a return connection 18 for returning media (detergent, pulsed air, paint) to a return 19, the material flow into the return 19 being controlled by a return valve RF2 in the color changer 14.
- the color changer 14 additionally has a reservoir valve VRE in order to be able to guide the paint standing in the branch line 9 into a reservoir.
- the reservoir is formed here by two pig lines 20, 21 which open into a pig station 22, 23 at their distal end.
- a pig 24, 25 can be displaced in each of the pig lines 20, 21, the movement of the pigs 24, 25 from the pig stations 22, 23 in the direction of the color changer 14 using compressed air, as is known per se from the prior art.
- the reservoir valve VRE is then first opened and the old paint in the branch line 9 is transferred into the pig line 20.
- fresh paint is then transferred from the ring line 4 through the reservoir valve VRE into the other pig line 21.
- the pig 24 then presses the old paint located in the pig line 20 back into the branch line 9 and finally also into the ring line 4.
- the pig 25 then presses the fresh paint located in the pig line 21 back into the branch line 9.
- FIGS. 3A and 3B will now be described below, which likewise corresponds to the second variant of the invention and is a modification of the exemplary embodiment according to FIG. To avoid repetition, reference is therefore made additionally to the preceding description, the same reference symbols being used for corresponding details.
- the color changer 14 is designed as a linear color changer and is arranged in a distal robot arm 26 of a painting robot.
- the color changer 14 here has two valve assemblies 14.1, 14.2 which can be displaced relative to one another along the double arrows in order to select one of the color valves F1-Fn of the valve assembly 14.1 for material removal.
- the coating agent outlet 15 of the valve assembly 14.2 of the color changer 14 is connected to the rotary atomizer 8 via a metering pump 27, the material output by the rotary atomizer 8 being controlled by a conventional main needle valve HNA in the rotary atomizer 8.
- the rotary atomizer 8 here has a return valve RF1A and a short flush valve KS, as is known per se from the prior art.
- the valve assembly 14.2 here also has a reservoir valve LFB, which corresponds to the reservoir valve VRE according to FIG.
- the reservoir valve LFB makes it possible to guide the paint standing in the branch line 9 into a reservoir, which consists of a connecting line 28 and a pig line 29, the pig line 29 having a larger line cross-section than the connecting line 28.
