Definitions
- the invention relates to a rotary atomizer for atomizing a coating agent, in particular for atomizing paint for painting motor vehicle body components.
- rotary atomizers are usually used as application devices. When using such rotary atomizers, it is desirable to determine the speed and direction of rotation of the rotary atomizer in order to enable the speed to be controlled or regulated.
- DE 102 37 128 A1 discloses a rotary atomizer that makes it possible to monitor the speed and direction of rotation of the rotary atomizer during operation.
- the known rotary atomizer has a rotating reflector disk that is scanned by an optical sensor.
- the disadvantage of this optical speed detection is the sensitivity to interference caused by dirt on the reflector disk.
- the invention is therefore based on the object of improving the speed detection in a rotary atomizer.
- the rotary atomizer according to the invention has, in accordance with the known rotary atomizers, a rotatably mounted rotor which rotates around a rotational axis at a certain speed during operation.
- the rotor has an atomizer shaft which has a mounting option for a bell plate at its distal end, for example in the form of a screw connection for screwing the bell plate onto the atomizer shaft.
- the rotary atomizer according to the invention in accordance with the rotary atomizers with a Wiegand sensor described above in the prior art, also has a magnet (e.g. magnetic disk) which rotates with the rotor and has several magnetic poles distributed over the circumference and thus a pole change in the circumferential direction.
- a magnet e.g. magnetic disk
- the rotary atomizer according to the invention also contains a magnetic sensor (e.g. Wiegand sensor) for detecting the pole changes of the magnetic field of the magnet rotating with the rotating rotor, wherein the magnetic sensor is arranged within a detection range around the magnet so that the magnetic sensor can detect the rotating pole changes of the magnetic field.
- a magnetic sensor e.g. Wiegand sensor
- the invention is based on the newly gained technical-physical knowledge that the rotating pole changes of the magnetic field in the materials of the rotary atomizer lead to eddy currents and induce magnetic counter fields that interfere with the speed measurement by the magnetic sensor (e.g. Wiegand sensor). In this way, a useful signal is superimposed at the location of the magnetic sensor (e.g. Wiegand sensor), which is caused by the rotating pole changes of the rotating magnet. with an interference signal that is generated by the induced magnetic opposing fields.
- the invention therefore provides that these disturbing eddy currents and magnetic opposing fields are reduced in order to reduce the susceptibility to interference of the speed detection.
- the rotary atomizer according to the invention is therefore preferably characterized by a material mix, wherein the material mix provides electrically poorly conductive materials (e.g. p > 0.1 Q.mm 2 /m) within the detection range around the rotating magnet, while electrically highly conductive materials (e.g. p ⁇ 0.1 Q.mm 2 /m) can be provided outside the detection range around the rotating magnet, as is also the case with conventional rotary atomizers.
- electrically poorly conductive materials e.g. p > 0.1 Q.mm 2 /m
- electrically highly conductive materials e.g. p ⁇ 0.1 Q.mm 2 /m
- the stationary magnetic sensor is spatially separated from the rotating magnet by an air gap, whereby the air gap can have a gap width of at least 0.1 mm, 0.5 mm, 1 mm, 2 mm, 5 mm or 10 mm.
- the air gap completely prevents the induction of currents and opposing fields in the area of the air gap, since air is electrically insulating.
- the magnet is shaped as a magnetic disk, wherein the magnetic disk is arranged coaxially to the axis of rotation and rotates with the rotor of the rotary atomizer.
- the magnetic disk can be pressed onto the atomizer shaft, to name just one example.
- the magnetic sensor is preferably located proximally behind the magnetic disk in the axial direction and is separated from the magnetic disk in the axial direction by the air gap mentioned above.
- the magnetic field runs essentially axially in the air gap.
- the length of the magnetic disk in the axial direction is significantly smaller than the radius of the magnetic disk.
- the at least one magnet is preferably embedded in an end face of the magnetic disk. If the magnetic sensor is arranged in the proximal direction in front of the magnetic disk (i.e. on the side of the painting robot and on the side facing away from the bell cup), the at least one magnet is then also embedded in the proximal end face of the magnetic disk.
- the rotating magnet is shaped as a magnetic sleeve, which can be pressed onto the atomizer shaft, for example.
- the magnetic sensor e.g. Wiegand sensor
- the magnetic sensor is radially separated from the rotating magnetic sleeve by the air gap mentioned above.
- the magnetic field in this variant runs essentially radially.
- the magnetic sensor in this variant is therefore preferably arranged radially outside the magnetic sleeve.
- the magnetic sleeve is hollow and has a radial thickness that is significantly smaller than the axial length and/or the radius of the magnetic sleeve.
- the magnetic sensor is arranged in an annular space that extends in the circumferential direction.
- the annular space can extend over the entire circumference around the axis of rotation.
- the annular space consists of at least one elongated hole that is curved in the circumferential direction and only extends over part of the circumference.
- the magnetic sensor is arranged in the elongated hole, preferably centrally with respect to the circumferential direction, so that the magnetic sensor is surrounded by the elongated hole on both sides in the circumferential direction. It should also be mentioned that the magnetic sensor preferably does not completely fill the annular space (e.g. elongated hole) in the radial direction, but rather leaves a free space radially inside.
- the annular space (e.g. slot) is preferably filled with an electrically insulating material, whereby the induction of eddy currents and opposing magnetic fields in the vicinity of the magnetic sensor is largely prevented, since eddy currents cannot form in the electrically insulating material.
- Filling the annular space (e.g. slot) with an electrically insulating material is also advantageous in order to avoid air turbulence in the annular space, which can otherwise arise in a hollow annular space and lead to mechanical power losses.
- the electrically insulating material in the annular space can be plastic.
- the invention includes a further inventive idea of its own worthy of protection.
- the disruptive eddy currents and opposing magnetic fields can also be reduced by using a laminated core consisting of numerous sheets that are electrically insulated from one another so that no eddy current can flow across the sheets.
- Laminated cores of this type are already known from transformers and therefore do not need to be described in more detail.
- the laminated core can contain more than 10, 20, 50 or 70 sheets that are electrically insulated from one another.
- the magnetic sensor e.g. Wiegand sensor
- the magnetic sensor is arranged at least partially in the laminated core, for example in an axial bore in the laminated core.
- the individual sheets of the laminated core preferably each lie in a plane that contains the rotation axis of the rotary atomizer.
- the individual sheets are therefore preferably arranged distributed over the circumference with respect to the rotation axis.
- the entire laminated core is therefore preferably arranged in a ring shape and coaxially to the rotation axis of the rotor. It is also possible that at least some of the sheets of the laminated core are slotted in order to optimally suppress the disruptive eddy currents.
- the sheets can, for example, consist of a so-called mu-metal, whereby such mu-metals are known per se from the prior art.
- the adjacent sheets of the laminated core can each be separated by an air gap, whereby the air gaps can also be filled with an electrically insulating material.
- the laminated core is preferably arranged within the detection range around the magnet.
- the invention aims to minimize the interference of the speed measurement by induced opposing fields.
- the magnetic field generated by the rotating The magnetic field generated by the magnet generates a useful signal with a maximum first magnetic field strength.
- the interfering counter-magnetic field generated by the induction currents generates an interference signal with a second maximum magnetic field strength at the location of the magnetic sensor.
- the interference suppression measures according to the invention now preferably enable a reduction of the second maximum magnetic field strength (interference signal) of the interfering counter-magnetic field to 30%, 20%, 10%, 5% or even just 2% of the first maximum magnetic field strength of the useful signal generated by the rotating magnet.
- the design measures according to the invention improve the useful signal/interference signal ratio in magnetic speed measurement.
- the magnetic sensor can be elongated and aligned with its longitudinal axis parallel to the rotation axis of the rotary atomizer.
- the magnetic sensor it is possible for the magnetic sensor to be elongated and aligned with its longitudinal axis radially in relation to the rotation axis of the rotary atomizer.
- the magnetic sensor can be arranged proximally in front of the magnetic disk in the axial direction, so that the air gap separates the magnetic sensor from the magnetic disk in the axial direction. The magnetic sensor then overlaps the magnetic disk in the radial direction.
- the radially aligned magnetic sensor on the circumference of the magnetic disk radially outside the magnetic disk, so that the air gap separates the magnetic sensor from the magnetic disk in the radial direction.
- the magnetic sensor is preferably a Wiegand sensor, as is known per se from the prior art (e.g. DE 10 2021 101 028 Al).
- Wiegand sensors are also referred to as pulse wire sensors and do not need to be described in more detail since they are known per se from the prior art.
- the invention is not limited to a Wiegand sensor with regard to the type of magnetic sensor.
- the rotor preferably has the magnetic sensor as a separate component that is connected to the rotor in a rotationally fixed manner.
- the magnetic sensor e.g. magnetic disk, magnetic sleeve
- the magnetic sensor can be pressed onto the atomizer shaft, to name just one example.
- the rotary atomizer can have a compressed air turbine to drive the rotor, as is the case with conventional rotary atomizers.
- the rotating magnet has several pairs of magnetic north poles and magnetic south poles alternating over its circumference, for example two, three or four pairs of magnetic poles.
- the distribution of the magnetic poles over the circumference of the rotor is therefore preferably not rotationally symmetrical in order to be able to detect both the speed and the direction of rotation of the rotor.
- the pulse sequence supplied by the magnetic sensor does not contain any information about the direction of rotation of the rotary atomizer. This is different if the magnetic poles in the rotor are not rotationally symmetrical, since the pulse sequence supplied by the magnetic sensor then also contains information about the direction of rotation of the rotary atomizer.
- the rotary atomizer according to the invention is preferably designed for atomizing paint when painting motor vehicle body components.
- the invention is not limited to paints with regard to the coating agent to be atomized, but can also be implemented with other types of coating agents.
- the rotary atomizer according to the invention is suitable not only for coating motor vehicle body components, but also for coating other types of components.
- Figure 1A shows a sectional view through a rotary atomizer according to the invention.
- Figure 1B shows an enlarged detail view of Figure 1A.
- Figure 2 shows a perspective view of a magnetic disk which is used in the rotary atomizer according to the invention for speed detection.
- Figure 3 shows an axial rear view of the rotary atomizer according to the invention.
- Figure 4 shows a magnetic sleeve as an alternative to the magnetic disk according to Figure 2.
- FIGS 8-10 show various modifications according to the invention with different arrangements of the magnetic sensor.
- the rotary atomizer 1 initially has, in the conventional manner, an atomizer shaft 2 which is part of a rotor and rotates about a rotation axis 3 during operation (see Figures 3, 5 and 6).
- the atomizer shaft 2 is driven in the conventional manner by a compressed air turbine, which is not shown for the sake of simplicity.
- the atomizer shaft 2 is rotatably mounted within an atomizer housing 4 in a conventional manner, whereby the bearings for the atomizer shaft 2 are also not shown.
- a magnetic disk 5 is pressed onto the atomizer shaft 2, which has several magnetic north poles N and magnetic south poles S distributed over the circumference, as can be seen in particular from Figure 2.
- the speed is detected by a Wiegand sensor 6, which is arranged in the atomizer housing 4, whereby the Wiegand sensor 6 is separated from the magnetic disk 5 by an air gap 7.
- the magnetic field B generated by the magnetic disk 5 runs essentially axially, i.e. parallel to the rotation axis 3 of the atomizer shaft 2.
- the direction of the magnetic field B in the air gap 7 changes continuously, i.e. pole changes occur in the air gap 7, which are detected by the Wiegand sensor 6 in the conventional manner.
- the Wiegand sensor 6 is arranged within a detection range 8 around the magnetic disk 5 so that the Wiegand sensor 6 can detect the pole changes that are generated by the rotating magnetic disk 5 in the air gap 7.
- the detection range 8 is only shown schematically in order to facilitate understanding of the invention. In fact, the detection range 8 does not have a circular or spherical shape.
- the Wiegand sensor 6 is arranged in the atomizer housing 4 in a slot 9 that extends in the circumferential direction, as can be seen in Figure 3.
- the Wiegand sensor 6 is arranged centrally in the slot 9 with respect to the circumferential direction, so that the Wiegand sensor 6 is surrounded by the slot 9 on both sides in the circumferential direction.
- the Wiegand sensor 6 does not completely fill the slot 9 in the radial direction, but leaves a radial free space 10 free radially inside.
- the arrangement of the Wiegand sensor 6 in the slot 9 is advantageous because no disruptive induction currents or opposing fields can be induced within the slot 9, which also reduces the sensitivity of the speed measurement to interference.
- the slot 9 can also be filled with an electrically insulating material, such as plastic. This is advantageous in order to avoid air turbulence in the slot 9, which would lead to mechanical power losses.
- Figure 4 shows a magnetic sleeve 11, which can be pressed onto an atomizer shaft, for example.
- the magnetic sleeve 11 also has several magnetic north poles N and magnetic south poles S distributed over the circumference in order to generate pole changes when rotating, as is also the case with the magnetic disk 5 according to Figure 2.
- the associated Wiegand sensor is preferably arranged radially on the outside and separated from the magnetic sleeve 11 by an air gap. In this variant with the magnetic sleeve 11, the magnetic field in the air gap between the magnetic sensor and the magnetic sleeve 11 runs essentially in the radial direction.
- Figure 5 shows a modification of a rotary atomizer 1 according to the invention, which is largely corresponds to the embodiment described above, so that in order to avoid repetition, reference is made to the above description, the same reference numerals being used for corresponding details.
- a special feature of this modified embodiment is that a laminated core 12 is arranged in the atomizer housing 4, which has numerous sheets 13 that are distributed over the circumference, as can be seen in particular from Figure 6, wherein the adjacent sheets 13 are each separated from one another by an air gap 14.
- the laminated core 12 therefore prevents eddy currents from flowing in the circumferential direction, since the adjacent sheets 13 are insulated from one another.
- the laminated core 12 therefore also helps to avoid the disruptive eddy currents that are generated when the magnetic disk 5 rotates.
- the Wiegand sensor 6 is arranged in an axial bore 15 that passes through the laminated core 12. It can also be seen from Figure 6 that the individual sheets 13 of the laminated core 12 each lie in a plane that contains the axis of rotation 3 of the rotary atomizer 1. In the sectional view according to Figure 6, the individual sheets 13 run in a radial direction.
- a special feature of this embodiment is that the magnetic north poles N and the magnetic south poles S are not arranged rotationally symmetrically over the circumference of the magnetic disk 5. This offers the advantage that not only is it possible to measure the speed, but also to determine the direction of rotation. Due to the non-rotationally symmetrical arrangement of the magnetic north poles N and the magnetic south poles S, the pulse sequence supplied by the magnetic sensor contains not only information about the speed, but also information about the direction of rotation of the rotary atomizer.
- the invention is not limited to the preferred embodiments described above. Rather, the invention also includes 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 includes various aspects of the invention that enjoy protection independently of one another. This applies in particular to the idea of using a laminated core in a rotary atomizer to minimize eddy currents.
- the idea of using a laminated core in a rotary atomizer to avoid eddy currents can therefore also be implemented within the scope of the invention without the special arrangement of materials with poor or good electrical conductivity within or outside the detection range.
- Figures 8-10 show various modifications according to the invention with different arrangements of the magnetic sensor 6. These modifications largely correspond to the embodiments described above, so that in order to avoid repetition, reference is made to the above description, the same reference numerals being used for corresponding details.
- the magnetic sensor 6 is elongated and its longitudinal axis is aligned parallel to the rotation axis 3 of the rotor, as is also the case in the embodiment according to Figure 1A.
- the magnetic sensor 6 is arranged proximally in front of the magnetic disk 5 in the axial direction, whereas in this embodiment the magnetic sensor 6 partially overlaps the magnetic disk 5 in the axial direction and is arranged on the circumference of the magnetic disk 5 radially outside the magnetic disk 5.
- the air gap 7 is therefore ring-shaped and separates the magnetic sensor 6 from the magnetic disk 5 in the radial direction.
- the magnetic sensor 6 is also elongated. However, the magnetic sensor 6 is aligned with its longitudinal axis radially in relation to the rotation axis 3. The magnetic sensor 6 is arranged on the circumference of the magnetic disk 5 radially outside the magnetic disk 5 and is separated from the magnetic disk 5 in the radial direction by the annular air gap 7.
- Figure 10 also shows the magnetic sensor 6 in a radial orientation with respect to the rotation axis 3 of the rotor.
- the magnetic sensor 6 is arranged proximally in front of the magnetic disk 5 in the axial direction and partially overlaps with the magnetic disk 5 in the radial direction.
- the annular air gap 7 thus separates the magnetic sensor 6 from the magnetic disk 5 in the axial direction.
- the invention enables a fault-insensitive detection of speed and direction of rotation in a rotary atomizer, which in turn enables reliable control and leads to shorter downtimes.
- the invention enables higher signal reserves for more stable control.
- the rotary atomizer according to the invention has a higher efficiency and thus has a lower air consumption across all operating points due to lower eddy current losses or lower air vortex losses.
