Definitions
- Coating device in particular rotary atomizer
- the invention relates to a coating device for coating components, in particular with a rotary atomizer for painting motor vehicle body components.
- rotary atomizers are usually used as the application device, which rotate a bell cup at high speed during the painting operation, with the bell cup throwing off the paint to be applied and thereby atomizing it.
- Electrostatic coating agent charging is usually used here in order to increase the application efficiency (i.e. the ratio of the paint deposited on the vehicle body components to be painted to the total amount of paint applied) and to correspondingly reduce the disruptive overspray.
- the vehicle body components to be painted are electrically grounded while the rotary atomizer is charged to a high-voltage potential, so that the paint applied is also electrostatically charged accordingly.
- the paint shops therefore have a high-voltage area and an electrically grounded area, with the high-voltage area containing the rotary atomizer.
- the rotary atomizers are usually driven by turbines that are driven by compressed air. It is also known from EP 1 389 488 A2 to monitor the speed of a rotary atomizer.
- the back of the turbine wheel is provided as a reflector disc with reflectors in the shape of segments of a circle, which are detected by an optical sensor (eg photo cell).
- the output signal of the optical sensor is then transmitted from the high-voltage area to the electrically grounded area via a fiber optic cable, with the fiber optic cable enabling potential isolation.
- a disadvantage of this known technical solution for monitoring the speed of a rotary atomizer is that the optical components (reflector disc, interfaces to the income in the optical waveguide, etc.) are susceptible to contamination.
- the invention is therefore based on the object of correspondingly improving the above-mentioned prior art.
- the coating device according to the invention initially has an electrostatic coating agent charge, as is known per se from the prior art and serves to electrostatically charge the applied coating agent.
- the coating device according to the invention therefore has a high-voltage area and an electrically grounded area.
- the coating device according to the invention also has a first sensor, which is arranged in the high-voltage area.
- the first sensor can be a speed sensor that is used to record the speed of the rotary atomizer.
- the invention is not limited to speed sensors with regard to the type of the first sensor. Rather, within the scope of the invention, the first sensor can alternatively also measure other operating variables of the coating device.
- the coating device according to the invention also has an optical waveguide in order to transmit the measurement signal of the first sensor from the high-voltage area to the electrically grounded area, with the optical waveguide also enabling potential separation between the high-voltage area and the electrically grounded area.
- the invention now differs from the prior art described at the outset according to EP 1 389 488 A2 in that the first sensor is a magnetic sensor, whereas in the prior art an optical sensor is used to scan the reflector disk.
- the use of a magnetic sensor instead of an optical sensor avoids the problems described above with regard to the susceptibility to contamination and the susceptibility to corrosion of the reflector disk.
- the coating device according to the invention is preferably a rotary atomizer.
- the coating device to have another type of atomizer, such as an air atomizer, an air atomizer, an airless atomizer or an ultrasonic atomizer, to name just a few examples.
- the coating device according to the invention is preferably a painting device which applies a paint as the coating agent.
- the scope of the invention it is in principle also alternatively possible for other types of coating compositions to be applied.
- the coating device according to the invention is preferably designed to coat motor vehicle body components.
- the scope of the invention it is fundamentally also possible as an alternative for other types of components to be coated.
- the magnetic sensor already mentioned above preferably generates an electrical signal which is then converted into a corresponding optical signal by a first electro-optical converter and coupled into the optical waveguide.
- the connection between the magnetic sensor and the electro-optical converter is established by an electric line.
- the magnetic sensor, the electrical line and the electro-optical converter are preferably arranged in the rotary atomizer, while the optical waveguide is located outside the rotary atomizer and establishes the connection to the electrically grounded area.
- the invention is preferably technically implemented in a rotary atomizer which has a bell disk shaft which can be rotated about an axis of rotation and serves to accommodate a bell disk, as is known from the prior art is known.
- the rotary atomizer is in this case arranged in the high-voltage area and has a first magnetic element which, during operation, rotates with the bell disk shaft of the rotary atomizer and generates an alternating magnetic field during rotation.
- the first magnetic sensor is stationarily arranged within the rotary atomizer and detects the changing magnetic field that is generated by the rotating first magnetic element.
- the rotary atomizer has a second magnetic element for detecting the direction of rotation, which also rotates during operation with the bell disk shaft of the rotary atomizer and thus generates an alternating magnetic field.
- the two magnetic elements are arranged in the circumferential direction with a certain angular offset, which is optionally not equal to 180°, in order to enable the direction of rotation to be identified.
- the rotary atomizer can have a second sensor, in particular a second magnetic sensor, for detecting the direction of rotation.
- the two magnetic sensors are preferably arranged with a specific angular offset in the circumferential direction, with the angular offset preferably being unequal to 180° in order to enable detection of the direction of rotation.
- two electro-optical converters can also be provided, which couple two signals into the optical waveguide, whereby the two signals can differ, for example, with regard to their wavelength in order to be able to distinguish the two signals from one another at the receiver end.
- the above-mentioned electro-optical converter for generating the optical signal can have a light-emitting diode, for example, but other light sources are also possible in principle in order to buy a corresponding optical signal into the optical waveguide.
- the magnetic element can be designed as a ring magnet, which is then preferably aligned coaxially to the axis of rotation of the bell disk shaft.
- the magnetic element is a bar magnet, which is then preferably aligned parallel to the axis of rotation of the bell disk shaft.
- the magnetic element is a magnetic mass which is arranged in a sleeve, the sleeve preferably being designed as a metal sleeve and being made of VA steel (stainless steel), for example.
- the ring magnet When using a ring magnet in a rotary atomizer, the ring magnet is preferably aligned coaxially to the axis of rotation of the bell cup shaft and rotates together with the bell cup shaft.
- the ring magnet can have a multi-pole magnetization with a plurality of magnetic poles which are distributed over the circumference of the ring magnet. If the magnetic sensor is arranged on the rotating ring magnet, the magnetic sensor then generates a corresponding pulse with each pole change.
- the magnetization of the ring magnet is not rotationally symmetrical with respect to the axis of rotation of the bell cup, so that the direction of rotation can also be identified.
- the magnetic sensor In the case of a rotationally symmetrical magnetization of the ring magnet, the magnetic sensor generates a pulse sequence that is independent of the direction of rotation and therefore does not enable the direction of rotation to be detected. Only the magnetization, which is not rotationally symmetrical with respect to the axis of rotation of the bell cup, enables such a detection of the direction of rotation.
- the ring magnet can be divided into several segments that alternate in the circumferential direction.
- the ring magnet is cast using injection molding technology.
- the rotating magnetic element can be a magnetic mass which is arranged in a sleeve, the sleeve with the magnetic mass rotating together with the bell cup shaft.
- the sleeve has a design-related speed stability and expands radially when a maximum speed is exceeded, thereby blocking the bell disk shaft.
- the sleeve can have one or more predetermined breaking points, which break when the maximum speed is exceeded, as a result of which the bell disk shaft is blocked.
- the sleeve also causes a speed limitation here, so that the speed of the bell disk shaft does not reach safety-critical values.
- a so-called Wiegand sensor is preferably used, with such sensors also being referred to as pulse wire sensors and being known per se from the prior art.
- the magnetic sensor generates an electrical signal which can then be converted into an optical signal and transmitted via the optical waveguide.
- the electrical signal generated by the magnetic sensor not only carries information about the direction of rotation and speed, but also contains electrical energy that can be used to power electrical components.
- the coating device according to the invention e.g. rotary atomizer
- an electrical energy store e.g. battery
- the load can be an electronic circuit (e.g. microcontroller) which is connected to the electro-optical converter in order to transmit information to the electrically grounded area via the optical waveguide.
- this information can relate to the operating time of the coating device or contain product identification data for identifying the coating device.
- the magnetization of the magnetic element can contain a code that not only enables the speed and direction of rotation to be identified, but also identifies the type of coating device or even identifies the coating device itself in terms of a serial number, thereby preventing product piracy.
- the coating device is a rotary atomizer that includes a pickup tube that extends between the turbine and the mounting flange of the rotary atomizer, the pickup tube containing the magnetic sensor and the electro-optical converter.
- the receiving tube can also contain other electronic components.

- FIGS. 8A-8D show various representations to clarify the speed detection by a magnetic sensor with a rotationally symmetrical magnetization.
- Figures 9A-9D show variations of Figures 8A-8D with an asymmetric magnetization.
- FIGS 10A-10D show variations of Figures 8A-8D with an additional rectifier.
- FIGS 11A-11D show variations of Figures 9A-9D with an additional rectifier.
- the exemplary embodiment according to FIG. 1 is now described below, which has a rotary atomizer 1 as the application device, which is of largely conventional design.
- the rotary atomizer 1 is used for painting motor vehicle body components with a paint and has a bell cup 2 for this purpose, which is screwed onto a bell cup shaft 3 and rotates about an axis of rotation at high speed during operation.
- a turbine 4 which is driven by compressed air, is used in the conventional manner to drive the bell disk shaft 3.
- the bell cup shaft 3 is connected to a ring magnet 5 , the ring magnet 5 being arranged coaxially to the bell cup shaft 3 and rotating with the bell cup shaft 3 during operation.
- a magnetic sensor 6 shown only schematically, which detects the changing magnetic field generated by the rotating ring magnet 5 and thus enables speed monitoring.
- the magnetic sensor 6 is designed as a Wiegand sensor (pulse wire sensor), but other types of sensors are also possible in principle.
- the magnetic sensor 6 is connected via an electric line 7 to an electro-optical converter 8 which converts the output signal of the magnetic sensor 6 into an optical signal and couples it into an optical fiber 9 .
- the rotary atomizer 1 is part of a painting system with an electrostatic coating agent charge, so that the painting system has a high-voltage area 10 and an electrically grounded area 11 .
- the rotary atomizer 1 is arranged in the high-voltage area 10 and is at high-voltage potential during the painting operation.
- the optical waveguide 9 enables a potential separation between the high-voltage area 10 and the electrically grounded area 11 , which also contains an opto-electrical converter 12 .
- the rotary atomizer 1 is moved during operation by a multi-axis painting robot, as is known from the prior art.
- the rotary atomizer 1 has a mounting flange 13 with a mounting pin 14, which can be attached to a corresponding mounting flange of the painting robot, as is known per se from DE 43 06 800 A1.
- the electro-optical converter 8 is here arranged in the mounting flange 13 .
- FIGS. 2-4 show various schematic representations to clarify the principle according to the invention of speed monitoring by means of a magnetic sensor.
- a rotor 15 is shown in general, which rotates about an axis of rotation 16 during operation, it being possible for the rotor 15 to be connected, for example, to the bell disk shaft of a rotary atomizer and to rotate with it.
- the rotor 15 there are two bar magnets 17, 18 which are arranged opposite one another and aligned axially.
- a magnetic sensor 19 which, for example, can be designed as a Wiegand sensor and, depending on the magnetic field generated by the bar magnets 17, 18, generates a corresponding electrical signal which drives a light-emitting diode 20.
- the light-emitting diode 20 then emits a pulse 21 each time one of the bar magnets 17, 18 passes through. It should be mentioned here that only one of the two bar magnets 17, 18 with the correct polarity generates a pulse 21 when passing the magnetic sensor 19, while the other bar magnet 17 or 18 does not generate a pulse 21 because of the wrong polarity.
- a further light-emitting diode 22 is provided in addition to the light-emitting diode 20, the two light-emitting diodes 20, 22 being connected in parallel and having opposite polarity. This means that when each of the two bar magnets 17, 18 passes through, a pulse 21 or 23 is emitted. This increases the measurement accuracy when detecting the rotational speed, since more pulses 21, 23 are generated per angle unit.
- a rectifier 24 is arranged between the magnetic sensor 19 and the light-emitting diode 20, so that here too a pulse 21 or 23 is emitted when each of the two bar magnets 17, 18 passes through.
- FIG. 5 shows a schematic representation which largely corresponds to FIG. 1, so that to avoid repetition, reference is made to the above description of FIG. 1, with corresponding details being identified by the same reference symbols.
- This illustration also shows how the output signal of the magnetic sensor 6 can also be used for the power supply of electrical components in the rotary atomizer 1 .
- a rechargeable battery 25 with a charging circuit is located in the rotary atomizer 1 , the battery 25 being supplied with current and charged by the output signal of the magnetic field sensor 6 .
- the battery 25 in turn feeds a microprocessor 26 with the electrical energy required for operation.
- the microprocessor 26 is connected to the electro-optical converter 8 on the output side and can thus transmit data via the optical waveguide 9 into the electrically grounded area 11 .
- this data can be product identification data that prevent product piracy.
- FIGS. 6 and 7 show a further modification of the exemplary embodiment according to FIG. 1, so that, in order to avoid repetition, reference is again made to the above description of FIG. 1, the same reference symbols being used for corresponding details.
- a special feature of this exemplary embodiment is that instead of the ring magnet shown in FIG. 1, a magnetic mass 27 is provided, which is cast into a magnet sleeve 28 made of VA steel.
- the magnetic mass 27 is magnetic here and has a plurality of magnetic poles distributed in the circumferential direction, as will be described in detail below.
- the magnetic sleeve 28 with the cast-in magnetic mass 27 rotates together with the bell disk shaft 3 during operation, so that the magnetic sleeve 28 generates a rotating magnetic field which is detected by the magnetic sensor 6 .
- the magnetic sleeve 28 with the magnetic mass 27 is not only used for speed detection and for controlling the magnetic sensor 6. Rather, the magnetic sleeve 28 also has a technical safety function.
- the magnetic sleeve 28 has predetermined breaking points 29 which break open when a certain speed is exceeded, so that the magnetic sleeve 28 then expands radially, which leads to the rotary atomizer 1 becoming blocked and thus becoming stuck. This results in a speed limitation that prevents the speed of the rotary atomizer 1 from increasing into safety-critical ranges.
- a further special feature here is that the magnetic sensor 6 and the electro-optical converter 8 are arranged together in a receiving tube 30 which extends in the rotary atomizer 1 from the mounting flange 13 to the turbine 4 .
- FIGS. 8A-8D serve to illustrate the principle of the rotational speed detection according to the invention by means of the magnetic sensor 6, which detects the magnetization of the ring magnet 5, as has already been explained above.
- FIG. 8A shows a rotationally symmetrical magnetization with equidistant distances between the individual magnetic poles N, S.
- the light-emitting diode 20 generates light pulses 31 that are equidistant.
- the light pulses 31 then generate corresponding voltage pulses 32 on the receiver side, which are also equidistant. This means that with the symmetrical magnetization shown, it is not possible to identify the direction of rotation.
- Figures 9A-9D therefore show a modification with a magnetization which is not symmetrical, as can be seen immediately from Figure 9A.
- the generated light pulses 31 and the resulting voltage pulses 32, 33 are not equidistant, which enables the direction of rotation to be identified.
- Figures 10A-10D show a modification of Figures 8A-8D with symmetrical magnetization but with the additional rectifier 24 mentioned above.
- FIGS. 11A-11D show a modification of FIGS. 10A-10D with an asymmetrical magnetization, which enables the direction of rotation to be identified.
- the invention is not limited to the preferred embodiments described above. Rather, the invention also includes variants and modifications that make use of the idea of the invention and fall within the scope of protection.
- the invention also claims protection for the subject matter and the features of the subclaims independently of the claims referred to in each case and in particular also without the features of the main claim. The invention thus comprises various aspects of the invention which are protected independently of one another.
