Definitions
- the invention relates to an operating method for an atomizer for painting components (e.g. motor vehicle body parts) with a paint. Furthermore, the invention relates to a correspondingly designed paint shop for carrying out the operating method.
- an atomizer for painting components e.g. motor vehicle body parts
- a paint shop for carrying out the operating method.
- the application devices usually used are rotary atomizers that have electrostatic paint charging in order to increase the application efficiency and to minimize the disruptive overspray (i.e. the proportion of the sprayed paint that does not get onto the motor vehicle body part).
- the electrostatic charging of the paint to be applied can take place here through an electrostatic external charging.
- electrodes (charging rings) are attached to the outside of the atomizer, which electrostatically charge the applied spray jet of paint.
- the external dimensions of the charging ring play at most a subordinate role, since there is sufficient space for the atomizer to move with the charging ring.
- the charging rings for the exterior painting therefore usually have so-called fingers with embedded electrodes, which protrude from the atomizer and therefore require a relatively large amount of space.
- the atomizer with the charging ring when painting the interior of motor vehicle body components, the atomizer with the charging ring must have relatively compact external dimensions, since there is only relatively little space for moving the atomizer with the charging ring in the interior of motor vehicle body components.
- the typical charging rings for the interior paint show therefore very short electrodes for electrostatic paint charging.
- painting robots for interior painting and painting robots for exterior painting are combined in a painting booth.
- the painting robots for the interior painting then guide an atomizer with a suitably adapted charging ring for the interior painting, which requires little space.
- the painting robot for exterior painting on the other hand, has an atomizer with a correspondingly adapted charging ring for exterior painting, which has protruding fingers with embedded electrodes and correspondingly requires more space.
- a disadvantage of this technical solution is the fact that specially adapted painting robots and atomizers are always required, which are optimized for the interior painting or for the exterior painting of the motor vehicle body components. This is associated with a relatively high effort.
- EP 3 320 981 A1 DE 10 2014 017 895 A1, EP 0 796 665 A2 and DE 10 2019 215 079 A1.
- the invention is therefore based on the object of reducing the effort involved in changing between interior painting and exterior painting in a painting facility.
- the operating method according to the invention uses an atomizer for painting components with a paint.
- the atomizer is a rotary atomizer, as is known per se from the prior art, so that a detailed description of the rotary atomizer can be dispensed with.
- a rotary atomizer is also the possibility within the scope of the invention that another type of atomizer is used instead of a rotary atomizer.
- automotive body components are painted.
- the components to be painted do not necessarily have to be motor vehicle body components. Rather, other types of components can also be coated within the scope of the invention.
- the operating method according to the invention initially provides, in accordance with the known painting methods according to the prior art, that the components to be painted are painted by the atomizer, with an add-on component being mounted on the atomizer.
- This add-on component can be, for example, an electrode arrangement (charging ring) which is used for the electrostatic external charging of the applied paint and is optimized for painting the outer surfaces of the motor vehicle body components (i.e. for the outer painting), as has already been explained above with regard to the prior art.
- the mounted add-on component is an electrode arrangement for the interior painting.
- the operating method according to the invention is characterized in that the add-on component mounted on the atomizer (e.g. electrode arrangement for the exterior painting) is replaced by another add-on component.
- the add-on component mounted on the atomizer e.g. electrode arrangement for the exterior painting
- this other add-on car component can be an electrode arrangement for electrostatic external charging, which is suitable and optimized for painting the interior of the motor vehicle body parts and is therefore used for interior painting.
- the invention is not limited to the exchange of add-on components that are optimized for the exterior painting on the one hand and for the interior painting on the other hand. It consists in Also within the scope of the invention is the possibility that the other add-on component is a protective cover that can cover an interchangeable interface on the atomizer. After the add-on component mounted on the atomizer has been dismantled (eg electrode arrangement for the exterior painting), the protective cover is then mounted on the interchangeable interface and thereby protects the interchangeable interface or the atomizer.
- the other add-on component is a handling tool that can be used to actuate vehicle assemblies.
- the handling tool can be used to open or close doors, hoods or flaps of the motor vehicle body components.
- an electrode arrangement for the electrostatic external charging or the handling tool is optionally mounted on the nebulizer.
- a painting robot can then also serve as a handling robot (e.g. door opener, hood opener).
- the other add-on component can also be a different type of add-on component.
- the invention is therefore not limited to the examples described above (electrode arrangement for interior/exterior painting, protective cover, handling tool) with regard to the other add-on components, but can in principle also be implemented with other types of add-on components that can be interchanged.
- a protective cover is replaced by a handling tool, to name just one example.
- the add-on components to be replaced are an electrode arrangement for the exterior painting on the one hand and an electrode arrangement for the interior painting on the other. It should be mentioned here that the invention optionally enables a change from an electrode arrangement for the exterior painting to an electrode arrangement for the interior painting or vice versa.
- the add-on component mounted on the atomizer (for example the electrode arrangement for the exterior painting) is first dismantled from the atomizer.
- the dismantled add-on component is then placed in a storage device.
- the other add-on component (eg electrode arrangement for the interior painting) is then then mounted on the atomizer.
- an electrode arrangement for external charging to an electrode arrangement for direct charging or without charging possible.
- the add-on component that has been dismantled and stored in the storage device can then also be cleaned in the storage device in order to remove paint residues from the add-on component.
- the add-on component can be sprayed with cleaning fluid for this cleaning, brushed off and blown with compressed air in order to clean the add-on component.
- the cleaning of the dismantled add-on component is carried out manually by a maintenance person.
- the add-on component is placed in the storage device and then cleaned by the maintenance person. It is advantageous here if the storage device is located outside of the paint booth, for example in a maintenance cell, so that the maintenance person does not have to enter the paint booth to clean the dismantled add-on component.
- the cleaning of the dismantled add-on component takes place automatically in a cleaning device.
- the cleaning device can also be located inside the paint booth, since the cleaning process does not require a maintenance person to access the paint booth.
- the add-on components to be replaced can each have a gripping contour (e.g. handle) in order to be able to grip the add-on component with a form fit and/or friction fit. This simplifies the manual handling of the dismantled add-on components in the storage device or in the cleaning device.
- a gripping contour e.g. handle
- the add-on components can be removed from the tray for manual cleaning or replacement using a transportable cleaning cover.
- This cleaning cover protects the add-on components (e.g. charger rings) from further contamination and mechanical destruction.
- the charging rings can also be stored or transported to other areas of the paint shop (e.g. for maintenance purposes or cleaning work) using the cleaning cover.
- the storage table is optionally equipped with a holder in which the cleaning cover can be stored. Conveniently, the charging ring can be turned in this holder so that manual cleaning can be carried out easily and thoroughly.
- the replacement of the add-on components usually takes much less time than cleaning the add-on components. This is important because the cleaning process in the prior art requires a relatively long interruption in the painting process.
- the attachment components can be exchanged either manually, robot-supported or manually or automatically by an external device.
- the same atomizer can be used both for interior painting and for exterior painting.
- the electrode arrangement is then mounted on the atomizer, which is optimized for the interior painting.
- the electrode arrangement that is optimized for the exterior painting is mounted on the atomizer.
- a coupling mechanism can be used, which enables the assembly or disassembly of the add-on components on the atomizer.
- This coupling mechanism can have, for example, a ball-type clamping mechanism, a magnetic coupling, a vacuum suction device, an adhesive connection or swiveling clamps.
- the coupling mechanism can optionally have an operating element in order to selectively release or fix the mechanical connection between the atomizer and the add-on component, it being possible for the operating element to be arranged on the add-on component so that the coupling mechanism can be activated by manual action on the operating element on the add-on component can be solved.
- the dismantled add-on component eg electrode arrangement for the exterior painting
- This drain device preferably has several storage locations for the different types of components.
- the storage device can have a first storage space for an electrode arrangement for the exterior painting and a second storage space for an electrode arrangement for the interior painting.
- the above-mentioned security against interchanging the storage locations can be achieved mechanically, for example by blocking surfaces, guide pieces, gripping means and/or clamping brackets.
- the electrode assemblies for exterior painting typically have numerous fingers with embedded electrodes projecting from the atomizer. These fingers can then be inserted into corresponding recesses in the storage locations.
- the electrode arrangement for the interior painting there are no such cutouts or the cutouts are closed by blocking surfaces, which ensures that they cannot be mixed up when they are stored.
- the security against interchanging is achieved by sensors that can distinguish the storage locations and/or the various add-on components from one another.
- the individual add-on components can each be provided with an RFID tag (RFID: Radio Frequency and Identification).
- RFID Radio Frequency and Identification
- the storage device can then have a corresponding RFID reader, which reads the RFID tag on the add-on component and assigns the add-on components to the correct storage locations.
- the storage locations can be arranged on a turntable that can be rotated about an axis of rotation, and the storage space can always be the same.
- the storage locations are therefore either in a cleaning position for cleaning the deposited add-on component or in a transfer position in which an add-on component is placed on the turntable or an add-on component is removed from the turntable.
- the rotation therefore preferably makes it possible to position the individual storage locations either within the storage device or at least partially outside of the storage device.
- the two storage locations are arranged on one or more displacement devices (eg displacement tables).
- the shifting device can shift the storage locations between a cleaning position within the storage device (eg inside the paint booth) and a transfer position outside the storage device (eg outside the paint booth). For cleaning, the storage location with the electrode arrangement to be cleaned is therefore moved into the storage device. In contrast, for depositing or for removal, the depositing location with the electrode arrangement to be cleaned or cleaned is moved out of the depositing device.
- the displacement device enables the respective storage space to be displaced transversely to the wall of the paint booth, i.e. in the horizontal direction.
- the charging rings can thus be transported into or out of the painting booth, with this displacement being able to take place manually or automatically.
- a separate depositing point can be provided for a soiled charging ring.
- a separate storage area can be provided for a cleaned charging ring.
- Different charging rings can also be provided for a painting robot, with the different charging rings being adapted, for example, for internal painting or for external painting.
- the displacement devices are arranged side by side. Alternatively, however, there is also the possibility that the displacement devices are arranged one above the other. However, the displacement devices are preferably arranged in the same booth wall of the painting booth.
- a stacking store can be provided, which can accommodate several stacked charging rings.
- the shifting devices can then be supplied with the respective charging rings from the stack store.
- a cleaning device to the displacement devices.
- two shifting devices can be seen, each of which offers a storage space.
- a larger number of displacement devices is provided. This also makes it possible to change different types of charging rings (e.g. for exterior painting or for interior painting) on a painting robot.
- An advantage of the invention is that no add-on component (e.g. charging ring) has to remain in the spray booth after it has been put down, so that there is also no risk of contamination.
- add-on component e.g. charging ring
- the storage device can be aligned horizontally, so that the add-on components are stored in the vertical direction on the storage device or are picked up by the storage device.
- the storage device is inclined to the horizontal, so that the add-on components are placed at an angle on the storage device or are picked up at an angle by the storage device.
- the storage device can have a swiveling device in order to swivel the stored add-on component, in particular about a horizontal swiveling axis. This can be advantageous in order to swivel the mounted component that has been stored into a special cleaning position within the storage device.
- the individual storage locations can each have a self-centering feature so that the add-on components to be stored are automatically centered at the respective storage location when they are stored.
- the storage device can have an optical display that shows whether the add-on component to be stored has been stored correctly.
- this optical display can have a first signal light (e.g. a green LED) to signal correct storage and a second signal light (e.g. a red LED) to signal incorrect storage.
- the atomizer is preferably guided by a painting robot that is arranged in a painting booth in which the components are painted.
- the components to be painted can be conveyed through the paint booth by a conveyor. This can be provided within the paint booth and a hand washing area to the Attachment components to be cleaned manually.
- the cleaning station is preferably located in the re area and not in the painting area.
- a maintenance cell can be provided in order to maintain the painting robot and/or the atomizer.
- These maintenance cells can be arranged, for example, at the corners of the paint booth. There is the possibility here that the individual maintenance cells are separated from the paint booth by a cell wall, with the cell wall being able to consist of glass and/or sheet metal, for example.
- the maintenance cells can optionally also have their own ventilation in order to ventilate the interior of the maintenance cell. In this case, the maintenance cells can have an insertion opening in order to be able to insert the nebulizer or a robot arm into the maintenance cell.
- the storage device for storing the add-on components of the atomizer can be arranged inside the maintenance cell.
- the storage device for storing the add-on components of the atomizer is arranged outside the maintenance cell in the paint booth.
- one of the storage areas of the storage device is arranged inside the maintenance cell, while another storage area of the storage device is arranged outside of the maintenance cell inside the paint booth.
- the cleaning device for cleaning the add-on components can be arranged outside the maintenance cell in the paint booth, in particular on the cell wall of the maintenance cell.
- the cleaning device for cleaning the add-on components is arranged inside the maintenance cell, in particular under the storage device.
- the storage device and the cleaning device can therefore be arranged one above the other.
- the cleaning device for cleaning the add-on components can be arranged in a stationary manner in the paint booth.
- the cleaning device for cleaning the add-on components is attached to the painting robot and can be moved within the painting booth with the painting robot.
- the painting installation according to the invention initially has an atomizer with one mounted on it Add-on component, as already described above.
- i painting system according to the invention a painting robot that moves the atomizer.
- the painting system according to the invention is distinguished from the prior art by an exchange station which makes it possible to exchange the add-on component mounted on the atomizer for another add-on component.
- the other add-on component can be an electrode arrangement for the interior painting, a protective cover or a handling tool, as has already been mentioned above in relation to the operating method according to the invention.

- Figure 16 shows a modification of Figures 8A-8C with a linear translation in place of the turntable.
- a first step S1 the interior of a motor vehicle body is painted.
- a rotary atomizer with a charging ring (electrode arrangement) for electrostatic paint charging is used for this purpose, with the charging ring being optimized for interior painting.
- the charging ring therefore has only very short electrodes which hardly protrude from the outer contour of the rotary atomizer, so that the rotary atomizer with the charging ring requires relatively little space for the internal painting. This is important because relatively little room for maneuver is available when the rotary atomizer is moved inside the vehicle body.
- a continuous check is then carried out to determine whether the interior painting should be ended and an exterior painting is planned. If this is not the case, the operating method according to the invention continues the interior painting in step S1.
- the charging ring for interior painting is placed in a first storage location of a storage device in a step S3.
- the charging ring for the interior painting is thus separated from the rotary atomizer and discarded.
- the rotary atomizer picks up a charging ring for the exterior paintwork from a second storage location of the storage device.
- This charging ring has so-called fingers with embedded electrodes, which protrude from the rotary atomizer and therefore require a relatively large amount of space.
- this is hardly a problem when painting the outside, because there is enough freedom of movement for the rotary atomizer when painting the outside.
- a step S5 the exterior painting can begin with the charging ring for the exterior painting.
- the discarded charger ring for interior painting can also be cleaned in a step S6, the details of the cleaning process will also be described in detail later.
- the cleaning of the charging ring for the interior painting in step S6 can therefore take place during the exterior painting in step S5. This is advantageous because it allows for the cleaning in step S6 does not require an interruption of the painting process i ⁇ the painting process only has to be interrupted for the relatively short period of time required for the change from the charging ring for the inner painting to the charging ring for the outer painting. However, this changing time is much shorter than the cleaning time required for cleaning the inner paint charging ring in the step S6.
- a continuous check is then carried out again as to whether the exterior painting has ended and whether a change is being made back to the interior painting. If this is not the case, the operating method according to the invention continues the exterior painting in step S5.
- step S8 in which the charging ring for the exterior paintwork is deposited in the second storage location of the storage device.
- the storage device for each of the two charging rings has an assigned storage space. The first storage space is used to hold the charging ring for interior painting, while the second storage space is used to hold the charging ring for exterior painting.
- the two storage locations are safe from being mixed up, as will be described in detail later.
- a step S9 the rotary atomizer then picks up the charging ring for the interior painting, which has been cleaned in the meantime, from the first storage location of the storage device.
- step S10 interior painting then takes place again with the charging ring for interior painting.
- step Sil the deposited supercharging ring is cleaned for the exterior painting.
- the cleaning process in step Sil does not require any interruption of the painting process. Rather, the painting process only has to be interrupted for the relatively short changeover time required to change from the charging ring for the exterior painting to the charging ring for the interior painting.
- step S12 a continuous check is then carried out again as to whether the interior painting should be ended in order to switch to the exterior painting.
- FIGS 2A- 2C show different views of such a storage space in the form of a storage ring 1, the has a hole in the middle into which a charging ring 2 can be inserted, whereby ring 2 is used for external electrostatic charging and is optimized for internal painting.
- the charging ring 2 therefore has electrodes 3 which are designed as stub electrodes and only protrude very slightly from the charging ring 2 . This is important for interior painting, because when painting the interior of motor vehicle bodies, there is only relatively little freedom of movement for the rotary atomizer with the charging ring 2, so that the charging ring 2 should have very compact external dimensions.
- the charging ring 2 for the interior painting can be locked in the storage ring 1 by means of several swiveling clamping brackets 4.1-4.3.
- the rotary atomizer with the mounted charger ring 2 is thus inserted coaxially into the deposit ring 1. Then the clamps 4.1-4.3 are locked and the connection between the rotary atomizer and the charging ring 2 is released. The rotary atomizer can then be removed from the deposit ring 1, with the charging ring 2 remaining in the deposit ring 1.
- the storage ring 1 cannot be mixed up.
