Definitions
- the invention relates to a coating agent supply device for supplying an application station (e.g. painting robot) of a coating system (e.g. painting system) with a coating agent to be applied (e.g. paint).
- a coating agent supply device for supplying an application station (e.g. painting robot) of a coating system (e.g. painting system) with a coating agent to be applied (e.g. paint).
- the coating agent supply device is located in a paint mixing room for supplying a pigging system in a painting booth of a painting system for painting motor vehicle body components with the paint to be applied.
- the invention also relates to an associated operating method.
- FIG. 1 shows a schematic representation of a conventional painting system for painting motor vehicle body components 1.
- the motor vehicle body components 1 to be painted are conveyed along a painting line through a painting booth in which four painting robots 2-5 are arranged on opposite sides of the painting line, each of which uses a rotary atomizer as an application device, although other types of application devices (e.g. print heads) can alternatively be used.
- a pig target module 6-9 is located on each of the individual painting robots 2-5, with the individual pig target modules 6-9 being connected to a pig source module 14 via piggable coating agent lines 10-13.
- the pig source module 14 is located at a transfer point 15 of a coating agent supply device, which is only shown schematically here and provides the paint to be applied.
- the coating agent supply device has a valve arrangement 16 at the transfer point 15, which is connected to a coating agent storage container 18 ("delivery container") via a non-piggable coating agent line 17.
- a coating agent storage container 18 (“delivery container")
- delivery container a coating agent storage container
- non-piggable coating agent line 17 a coating agent storage container 18
- only the coating agent storage container 18 is shown as the only coating agent storage container. In practice, however, up to four coating agent storage containers 18 can be provided, which are connected to the transfer point 15 via a color changer.
- Figure 2 also shows a schematic representation of such a conventional painting system, so that in order to avoid repetition, reference is made to the above description, with the same reference numerals being used for corresponding details.
- the coating agent storage container 18 has a coating agent pump 19 in order to circulate the paint to be applied from the coating agent storage container 18 in a pump circuit, wherein the pump circuit has a feed line 20 from the coating agent pump 19 to the transfer point 15 and a return line 21 from the transfer point 15 to the coating agent storage container 18.
- the pump circuit with the feed line 20 and the return line 21 is also not piggable.
- One disadvantage is that previously only four of the coating agent storage containers 18 could be connected to the transfer point 15, so that only four different colors could be applied. If, on the other hand, a different color is to be applied, it is necessary to replace one of the coating agent storage containers 18 with another of the desired color. When replacing one of the coating agent storage containers 18 in this way, it is necessary to free the entire pump circuit with the feed line 20 and the return line 21 of paint residues, which requires a flushing process. This leads to high detergent consumption and correspondingly high disposal costs for the disposal of the paint and detergent residues. In addition, such a color change by replacing one of the coating agent storage containers 18 is very time-consuming.
- a further disadvantage is that the paint must continuously circulate in the pump circuit in order to prevent paint from settling in the feed line 20 or the return line 21. This permanent paint circulation is associated with an undesirable shear stress on the paint.
- Another problem with the known coating agent supply device is the shear stress on the paint, which must circulate even when no application is taking place.
- the invention is therefore based on the object of creating a correspondingly improved coating agent supply device and an associated operating method for such a coating agent supply device.
- This object is achieved by a coating agent supply device according to the invention or by a corresponding operating method.
- the coating agent supply device is preferably located in a paint mixing room of a painting system for painting motor vehicle body components and provides the paint to be applied at a transfer point.
- the invention is not limited to paints with regard to the coating agent to be applied, but can also be implemented with other types of coating agents.
- the invention is not limited to motor vehicle body components with regard to the components to be coated, but can also be implemented with other types of coating systems that coat other types of components.
- the coating agent to be applied is taken from a coating agent storage container ("delivery container") in the coating agent supply device, which usually has a large capacity sufficient to coat numerous components.
- this line arrangement between the coating agent storage container and the transfer point cannot be pigged, which is associated with the disadvantages described at the beginning.
- the invention therefore provides that the line arrangement between the coating agent storage container and the transfer point contains at least one piggable line.
- the coating agent supply supply device has several coating agent storage containers in order to provide different coating agents.
- each coating agent storage container can contain paint of a certain color.
- the inventive design of the coating agent supply device which is described in more detail below, enables more than four different coating agent storage containers to be provided. For example, 15 different coating agent storage containers can be provided in order to provide a correspondingly large number of different colored paints without it being necessary to replace one of the coating agent storage containers.
- the individual coating agent storage containers are preferably each connected to a pig line system.
- the individual pig line systems each contain a pig station with a pig source module and a pig target module as well as a piggable line between the pig source module and the pig module.
- Such pig line systems are known from the prior art and therefore do not need to be described in more detail. However, such pig line systems have not yet been used in a coating agent supply facility to connect the coating agent storage containers to the transfer point.
- each of the coating agent storage containers is assigned a pig line system.
- the invention also claims protection for a coating agent supply device in which a separate pig line system is provided for only some of the coating agent storage containers.
- the pig source module and the pig target module are each plate-shaped and mechanically firmly connected to one another, with the pig source module and the pig target module lying parallel to one another.
- the pig source module and the pig target module are therefore both located in the pig station and thus in approximately the same place, which enables material circulation, as will be described in more detail below.
- the piggable lines can be very long, since coating agent residues can be pigged back into the respective coating agent storage container during application breaks or when changing color ("reflow"), thereby avoiding the disruptive losses of rinsing agent and paint residues described above.
- This offers the possibility of the piggable lines having a length of more than 1 m, 2 m, 4 m, 10 m, 20 m, 50 m, 100 m or even more than 150 m.
- the longer line length between the transfer point made possible by the invention and the coating agent storage containers in turn allows for greater flexibility in the structural design of the coating agent supply system.
- the connection between the individual coating agent storage tanks and the associated pigging line systems is preferably made by a pump circuit.
- a circulation line is provided in the circuit, which starts from the respective coating agent storage tank, leads to the associated pigging station and then goes back to the respective coating agent storage tank, whereby this circulation line is preferably not piggable.
- the circulation line therefore comprises a supply line from the coating agent storage tank to the pigging station and a return line from the pigging station to the coating agent storage tank.
- the individual pump circuits preferably contain a circulation pump that takes the coating agent from the respective coating agent storage container and circulates it in the respective pump circuit.
- the circulation pump takes the respective coating agent from the respective coating agent storage container and conveys it through the feed line to the pigging station.
- the individual pump circuits can each contain a return flow regulator, which is arranged in the pump circuit downstream behind the respective pigging station in the return line and regulates the coating agent pressure at the associated pigging station.
- a return flow regulator is particularly useful if several distribution stations are arranged in the paint mixing room circuit described below.
- the individual pump circuits can each contain a controllable valve that is arranged in the respective pump circuit upstream of the pig station in the feed line and directs the coating agent flow either to the respective pig station or to a return line.
- This controllable valve is preferably a two-way valve. On the one hand, such a two-way valve enables the discarding of residual flushing agent from the circulation pump. On the other hand, the two-way valve also enables the pig source module to be filled without bubbles.
- the individual pig target modules are connected to the associated pig source module not only by the piggable line, but also by an additional connecting line, which is not piggable in the preferred embodiment of the invention.
- this connecting line enables material circulation through the piggable line and the connecting line, whereby material circulation is also possible in a large circuit that includes the pump circuit and the pig line system (paint mixing room circuit).
- the material circulation then starts from the coating agent storage tank via the feed line to the pig source module, through the piggable line to the pig target module, via the connecting line back to the pig source module and then via the return line back to the coating agent storage tank.
- the connecting line between the pig target module and the pig source module also enables unapplied coating agent to be returned from the piggable line via the pig target module through the connecting line and the pig source module and the pump circuit back into the respective coating agent storage container ("re-flow").
- the individual pigging stations can each contain a controllable valve arrangement, whereby this valve arrangement, depending on its control, preferably enables one of the following flow patterns in the coating agent supply device:
- the coating agent flows from the coating agent storage tank via the circulation line of the pump circuit to the pig source module and from there into the piggable line in order to fill the piggable line with the coating agent.
- the pump circuit and the associated pig line system together form a large circuit with material circulation from the coating agent storage tank, via the pump circuit to the pig source module, through the piggable line to the pig target module, through the connecting line to the pig source module and through the pump circuit back to the coating agent storage tank.
- Flushing agent and/or pulsed air is introduced at the pig source module and flows via the piggable line to the pig target module and from there via the connecting line to the pig source module and further into the circulation line and finally in a repatriation.
- the individual coating agent storage containers are preferably each assigned a pig line system in order to guide the coating agent to be applied to the transfer point.
- the individual pig line systems are preferably connected to a common distribution station.
- the common distribution station is therefore connected to the piggable lines on the supply side in order to remove the coating agent from the piggable lines.
- the distribution station is connected to the transfer point via at least one central channel.
- the common distribution station contains a controllable valve unit in order to optionally controllably connect the piggable lines to the at least one central channel on the application side.
- the at least one central channel between the distribution station and the transfer point is not piggable in the preferred embodiment.
- central channels can be provided between the distribution station and the transfer point, such as two, three or four central channels.
- the central ducts preferably have a relatively short pipe length, which is preferably less than 1 m.
- the distribution station preferably contains a distribution module for each of the pig line systems in order to remove the coating agent from the associated piggable line.
- the individual distribution modules are preferably plate-shaped and of identical construction, which enables a modular and expandable structure of the distribution station.
- the individual plate-shaped distribution modules are then preferably aligned parallel to one another and arranged in a row next to one another.
- the distribution modules are mechanically connected to one another, in particular by a screw connection.
- a correspondingly large number of distribution modules can then be integrated into the distribution station.
- the distribution station for each piggable line preferably has a passage channel through which a pig can pass, so that the piggable lines each pass through the distribution station.
- a through channel is preferably provided in each of the distribution modules.
- the common distribution station has a number n of inputs for the piggable lines on the supply side.
- the common distribution station has a number m of outputs for the central channels to the transfer point on the application side.
- the number n of inputs for the piggable lines is preferably greater than the number m of outputs for the central channels.
- the number m of outputs for the central channels can be two, three or four, while the number n of inputs for the piggable lines is greater than four.
- At least one pig sensor is arranged on the individual piggable lines in order to detect a pig in the piggable line.
- pig sensors are known per se from the prior art and therefore do not need to be described in more detail.
- the pig sensor is preferably arranged on the pig station, in particular at a distance from the pig station of less than 50 cm, 20 cm, 10 cm or 5 cm.
- a double pig sensor can be used that can monitor both the pig supply line and the pig return line. On the one hand, the double pig sensor can therefore detect whether a pig is entering the pig source module or leaving the pig source module. On the other hand, the double pig sensor can also detect whether a pig is moving into the pig target module or leaving the pig target module.
- the at least one coating agent storage container can be exchangeable and usually has a large capacity that is sufficient for coating numerous components.
- this capacity can be at least 10 l, 50 l, 100 l, 250 l or 500 l.
- the number of coating agent storage containers can be greater than two, three, four, five or even greater than ten. Due to the relatively large number of coating agent storage containers connected at the same time, many different coating agents can be applied without replacing a coating agent storage container, thereby avoiding the annoying color change losses described at the beginning.
- the coating agent supply device according to the invention which provides the respective coating agent at the transfer point, has been described above. However, the invention also claims protection for a coating system which additionally has an application station which is connected to the transfer point of the coating agent supply device and has at least one application device (eg rotary atomizer) in order to apply the coating agent provided at the transfer point.
- the transfer point can therefore have a pig source module on the application side, which is connected to a pig target module on an application device via at least one piggable line.
- the piggable line between the transfer point and the application device can have a relatively long line length, which can be in the range of 30 m to 200 m, for example.
- the individual pig target modules of the application station can each be connected to the pig source module at the transfer point via several parallel piggable lines. This facilitates the application of different coating agents.
- the application device is preferably an atomizer (e.g. rotary atomizer).
- atomizer e.g. rotary atomizer
- other application devices can also be used within the scope of the invention, such as so-called print heads.
- the application device is guided by an application robot, whereby several such application robots can be provided in an application station.
- Circulation of the coating agent in the large circuit, which is formed by the pump circuit and the associated pig line system, preferably located in the paint mixing room is formed, wherein the coating agent flows from the coating agent storage tank via the circulation line of the pump circuit to the pig source module, through the piggable line to the pig target module, through the connecting line to the pig source module and through the circulation line back to the coating agent storage tank.
- the coating agent supply device can be played. To do this, the following steps are preferably carried out: • Introducing flushing agent and/or pulsed air at the pig source module into the piggable line of the coating agent supply device.
- Figure 1 shows a schematic representation of the conventional painting system described above for painting motor vehicle body components.
- Figure 2 shows a modification of the conventional painting system according to Figure 1.
- Figure 3 shows a modification of the painting system according to Figure 1 according to the invention.
- Figure 4 shows a modification of the painting system according to Figure 2 according to the invention.
- Figure 5 shows a perspective view of a pigging station of the painting system according to the invention according to Figures 3 and 4.
- Figure 6 shows a sectional view of a pig source module of the painting system according to the invention.
- Figure 7 shows a plan view of a distribution station of the painting system according to the invention.
- Figure 8 shows a detailed view of a plate-shaped distribution module of the distribution station from Figure ?.
- Figure 9 shows the painting system according to Figure 4 in a basic position.
- Figure 10 shows the painting system according to Figure 4 when applying a paint.
- FIG 11 shows the painting system according to Figure 4, where the pressing is completed and material circulation takes place.
- Figure 12 shows the painting system from Figure 12 pushing paint back into a coating agent storage container.
- Figure 13 shows the painting system from Figure 4 during a rinsing process.
- Figure 14 shows a flow chart to illustrate the operating method according to the invention.
- the exemplary embodiment of a coating agent supply device according to the invention is now described below, as shown in Figure 3 and in a slightly modified form in Figure 4.
- the exemplary embodiment according to the invention partially corresponds to the conventional coating agent supply device as shown in Figures 1 and 2. To avoid repetition, reference is therefore made to the above description, with the same reference numerals being used for corresponding details.
- a special feature of this embodiment is that three parallel piggable coating agent lines 10-13 run between the pig target modules 6-9 and the pig source module 14 at the transfer point 15, so that three different paints can be provided at the pig target modules 6-9.
- a further special feature of this embodiment is the structural design and the functioning of the coating agent supply device upstream of the transfer point 15.
- the paint to be applied is provided by a total of 15 coating medium storage containers 18, whereby a larger or smaller number of coating medium storage containers 18 is also possible.
- the coating agent storage containers 18 each have a coating agent pump 19, which removes the paint from the respective coating agent storage container 18 and conveys it to a pig source module 23 via a non-piggable feed line 20 and a dual valve 22.
- a non-piggable return line 21 leads from the pig source module 23 back to the coating agent storage container 18.
- the feed line 20 and the return line 21 therefore form a pump circuit that cannot be pigged and enables material circulation in the pump circuit.
- each of the 15 coating agent storage containers 18 is assigned a pump circuit, which leads to a pig source module 23.
- a pump circuit which leads to a pig source module 23.
- a return flow regulator 24 is arranged in the return line 21 of the pump circuit, which regulates the paint pressure at the pig source module 23 to a predetermined value.
- the dual valve 22 can forward the paint supplied via the feed line 20 either to the pig source module 23 or via a return line 25 to a return line 26.
- a piggable coating agent line 27 leads through a distribution station 28 to a pig target module 29, wherein the pig target module 29 is mechanically connected to the pig source module 23, as can be seen from Figure 5.
- a connecting line 30 also runs from the pig target module 29 to the pig source module 23, whereby the connecting line 30 cannot be pigged.
- the piggable coating agent line 27 between the pig source module 23 and the pig target module 29 thus forms a paint mixing chamber circuit together with the connecting line 30.
- the paint is then taken from the coating agent reservoir 18 and flows via the feed line 20 and the dual valve 22 into the pig source module 23. From there the paint then flows further via the piggable coating agent line 27 through the distribution station 28 to the pig target module 29. From the pig target module 29, the paint then flows through the connecting line 30 to the pig source module 23 and from there via the return line 21 back to the coating agent storage container 18.
- a double pig sensor 30 is provided, which can detect when a pig passes the double pig sensor 30 in the piggable coating agent line 27. On the one hand, the double pig sensor 30 can therefore detect whether a pig 32 enters the pig source module 23 or exits the pig source module 23. On the other hand, the double pig sensor 32 can also detect whether a pig 32 moves into the pig target module 29 or leaves the pig target module 29.
- each of the coating agent storage containers 18 is assigned not only a pump circuit, but also a paint mixing chamber circuit. However, for the sake of simplicity, only a single paint mixing chamber circuit is shown in the drawings.
- Figure 6 shows a sectional view of the pig source module 23, wherein the pig target module 29 is of identical construction, so that a separate description of the pig target module 29 can be dispensed with.
- a pig 32 is shown in the pig source module 23.
- the pig 32 can then be moved by compressed air drive from the pig source module 23 through the piggable coating agent line 27 to the pig target module 29.
- the pig source module 23 has several valves 33-36.
- the functionality of the pig source module 23 is basically known from the state of the art and therefore does not need to be described in detail.
- the distribution station 28 has numerous plate-shaped distribution modules 39, whereby the number of distribution modules 39 can be changed due to the modular structure of the distribution station 28.
- the distribution station 28 has nine of the distribution modules 39.
- the distribution station 28 has only three of the distribution modules 39.
- Figure 8 shows a sectional view through the distributor module 39. It can be seen that a through-channel 40 passes through the distributor module 39, whereby the through-channel 40 can be passed through by the pig 32.
- the distribution module 39 has several valves 41-44 to control the removal of material from the passage channel 40.
- the distribution station 28 has a certain number of input connections 45 on the supply side in order to be able to connect one of the piggable coating agent lines 27.
- the distribution station 28 has a certain number of output connections 46 on the application side in order to be able to connect one of the central channels 37, 38.
- the distribution station 28 has nine input connections 45 and two output connections 46. In Figure 4, however, the distribution station 28 has only three input connections 45 and two output connections 46.
- FIG. 10 now shows the pressing on with paint.
- the coating agent pump 19 then conveys the paint from the respective coating agent storage container 18 via the feed line 20 to the pig source module 23 into the piggable coating agent line 27, whereby the pig 32 is moved towards the pig target module 29.
- Figure 11 now shows the state when the pressing is completed and material circulation takes place.
- the coating agent pump 19 conveys the respective paint from the coating agent storage container 18 through the feed line 20 to the pig source module 23. From the pig source module 23, the paint then flows via the piggable coating agent line 27 to the pig target module 29. From there, the paint then flows through the connecting line 30 to the pig source module 23 and from there via the return line 21 back into the coating agent storage container 18.
- This material circulation therefore includes both the pump circuit and the paint mixing room circuit.
- Figure 12 shows a reflow operation in which paint is pressed back into the coating agent storage container 18. In this case, the pig 32 is moved by compressed air in the piggable coating agent line 27 back to the pig source module 23.
- the pig 32 pushes back the paint column located in the piggable coating agent line 27.
- the paint located in the piggable coating agent line 27 is then pressed out of the pig source module 23 via the return line 21 back into the coating agent storage container 18.
- Figure 13 shows a flushing process. Pulsed air and flushing agent are introduced into the piggable coating agent line 27 at the pig source module 23 in order to clean it.
- FIG 14 shows a flow chart to illustrate the operating method according to the invention.
- step S1 the painting system is first brought into the basic position, which is shown in Figure 9 and was described above.
- step S2 the paint is then pressed on, as shown in Figure 10 and described above.
- step S3 shows the state according to Figure 11, in which the pressing is completed and material circulation takes place.
- step S4 The actual painting operation then takes place in step S4.
- the distribution station 28 takes the desired paint from the piggable coating agent line 27 and forwards it to the painting robots 2-5 via the transfer point 15.
- step S5 the reflow operation is carried out as shown in Figure 12 and described above.
- step S6 a rinsing operation is carried out as shown in Figure 13 and described above.
- the invention is not limited to the preferred embodiments described above. Rather, the invention also includes a large number of variants and modifications that also make use of the inventive concept and therefore fall within the scope of protection.
- the invention also claims protection for the subject matter and the features of the subclaims independently of the respective claims referred to and in particular also without the features of the main claim. The invention therefore comprises various aspects of the invention which are protected independently of one another.
- the invention enables the connection of a large number of paint systems to the transfer point to the pigging system of the painting system, i.e. more than four coating agent storage containers ("delivery containers") with different paints can be provided.
- the invention enables significantly faster color availability when more than four different paints are applied, since the different paints can be kept in the paint mixing room circuit without the need to replace one of the coating agent storage containers ("delivery containers").
- the invention enables a reduction in conventional ring line systems so that in the case of paints that are rarely required ("low runner”), no additional paint waste is generated due to the shear stress on the paint.
- the invention enables higher system availability, i.e. the necessary interruptions in application operation are shortened.
