Definitions
- the present invention relates to a method and a device for coating relative substrates moved to the device with a Powder layer, e.g. a powder coating application area
- this method and device is powder coating of substrates, especially with uniform surface geometry.
- substrates are, for example, steel and aluminum strip material (Coil), sheet metal boards, wood and wood-based panels, e.g. MDF (medium density fibreboard) or HDF (high-density fiberboard), plastic panels, Metal and plastic foils, paper webs, Extruded materials (profiles, pipes) and cables.
- Such powder coating processes are particularly popular for high throughput speeds of the coating substrate applied up to 3 m / s. applications this is, for example, the powder coating of insulation boards that supported electrostatically Applying abrasive grain to paper and Plastic film, the solder powder application on Extruded materials, the clear powder coating of wallpaper and powdering equipment e.g. For electrical cables or in the food sector.
- the detachment of the powder particles is additionally supported in which the Powder particles in the transmission area are electrically charged can be and so the particles differ from the transfer band due to the electrostatic It is easier to detach the repulsive force from its surface can. This also causes agglomeration of the Avoided particles. Just through the powder charge is a transfer of the particles to the substrate not possible.
- the object of the present invention is therefore a Powder coating process and an apparatus to provide for this, with the uniform homogeneous powder layers with a defined thickness high consistency even at high process speeds can be applied.
- a transfer device for example a transfer belt or a transfer roller
- This can, for example, in a fluidizing container or by spraying on Electrostatic forces are applied.
- the Transfer belt or the transfer roller are then like this moved that they are in a transmission range with the powder-coated surface of the surface to be coated Surface of the substrate lie opposite.
- the substrate and the transfer device can also be moved transversely to each other. Be moved the substrate and / or the transfer device. According to the invention, one is now found in the transmission range Transfer of the powder particles from the transfer device onto the substrate by means of electrostatic Forces instead.
- Electrode for example a corona electrode
- this Electrode becomes an electrostatic field between the electrode and generated the substrate.
- the particles are now through this electrostatic field from the transfer device solved and due to the electrical Force applied to the substrate.
- the two Electrodes are at different potentials, so that through the transfer device and the substrate a defined electrical field is built up throughout can be.
- the inventive method and the inventive Device can now powder layers Defined thickness with a consistency not previously possible even at very high process speeds on substrates be applied. This is particularly easy possible with substrates with a uniform surface geometry. Because of the reproducible controllable Amount of on the transfer device and last on the powder transferred to the substrate are also very low Powder quantities per unit of time in contrast to State of the art transferable. So that are thin-layer applications reproducible down to a few ⁇ m thickness possible. The thickness of the layer is determined thereby essentially from the speed of the Transfer device, the speed and the relative Direction of movement of the substrate as well the amount of applied to the transfer device Powder.
- the powder material transferred to the substrate without losses i.e. elaborate technical measures for recovery and recycling the not on the substrate deposited powder, as in the previous electrostatic powder application using spray organs are required. This is with less Space requirements and lower investment costs connected. Because the powder is not like the conventional one Technology is sprayed on, it is not necessary associated high compressed air consumption.
- the substrate join the electrostatic Powder coating process according to the prior art usual layer thickness fluctuations and particle size separations not on.
- the one to be transferred Powder quantity can be reproduced in a wide range can be controlled so that constant layer thicknesses both at low and at high conveyor speeds of the substrate up to approx. 3 m / s can be. In particular, can also be very thin layers reproducible down to a few ⁇ m thickness be generated.
- inventive method and the inventive Device are suitable for the transfer of both electrically non-conductive powder material as well electrically conductive or semi-conductive powder material.
- Figures 1 to 11 show different ones Devices or parts according to the invention hereof.
- Fig. 1 shows an inventive device for coating a substrate 10 with electrical non-conductive powder particles.
- the invention Process for coating the substrate be applied from above or from the side.
- the transfer belt is then used, for example guided accordingly by pulleys. This is for example in FIGS. 7 and 8.
- a vertical coating is shown in FIGS. 9 and 10.
- the substrate can continue on the one hand in the same or in the opposite direction how to move the transfer device.
- Fig. 1 shows a fluidizing container 1 with a feed 2 for unipolar ionized fluidizing air. With this fluidizing air becomes a powder feed 4 supplied paint powder fluidized.
- This Paint powder is made of an electrically non-conductive Material and is also charged unipolar.
- In the fluidizing tank 1 dips in a separation area 8 a roller 5 with a roller surface 6 on. This roller is in the area of the fluidizing container 1 deposited with a fixed core 11.
- This core 11 is electrically conductive, for example made of metal and grounded with a ground 12. in the The area of the fluidizing container now carries the electrostatic Field between the grounded core 11 and the polarized powder particles so that they too the roller 5 pulled and on the surface 6 as Powder coating 7 are deposited.
- the roller is now turned in the direction of arrow A, so that the coated surface 6 of the roller 5 itself moved out of the fluidizing container. With that leaves the area deposited by the core 11 and enters a transmission area not stored 9 in which the surface 6 of the roller 5 is parallel to a substrate moving in direction B. Outside each of the transmission range 9 behind the substrate or behind the roller 5 is one High voltage electrode 14, 14 'arranged. Generate these an electrostatic field that the unipolar charged powder particles towards the insulating Substrate 10 from the roller surface 6 to the substrate 10 moves. So that the paint powder from the Transfer roller 5 to the substrate 10.
- this one electrode 13 which serves to residual To remove charges on the surface 6 of the roller 5.
- the depolarized surface then dips 6 of the roller 5 back into the fluidizing container 1 a, in the area of which it is deposited by the core 11 is. As a result, it can absorb powder again.
- the overall result is that the coating 7 the roller surface 6 as a coating 15 of the substrate 10 is put down. Since none here Air flows are used, there is a turbulence-free Transfer of the powder, creating an extreme homogeneous and thin powder layer can be produced can.
- Fig. 2 shows another example, but in the as a transfer device instead of a roller 5, a belt 19 is used. This is done over three guide rollers 22, 22 ', 22' 'on the one hand through the fluidizing container 1 guided and then over the rollers 22 ', 22' ' guided in the same direction B parallel to the substrate 10. The further arrangement of this device is the same as in Fig. 1.
- roller 22 is now electrical conductive, for example made of metal.
- the vent 3 is not shown in FIG. 2 the fluidizing container 1.
- the belt moves here at a belt speed of approx. 1 m / s and is in turn polarized Powder particles coated as coating 7. These powder particles are negative in this example polarized.
- the electrodes 14, 14 'and 13 are corona electrodes as in FIG. 1 or "corona pincushion". These can be movable so that by slight vibration this pincushion an optimized detachment of the powder enters from volume 19. While the electrode 14 'for negatively polarized powder particles has negative voltage, the electrode 14 either be grounded or a positive voltage exhibit. The same applies to the electrode 13, by means of of having a full discharge of the tape bipolar ionized air of a corona discharge or is caused by passive ionization.
- the present device a suction 24 on the back of volume 19. This will be on the back entrained powder particles removed during the front with the coating 7 is not is changed. Furthermore, between the rollers 22nd and 22 'provide the band with a deposit 20, which is grounded. This deposit 20, for example a metal sheet, leads to this too Transport area the polarized particles better stick to the surface of the conveyor belt.
- Fig. 3 shows a further device, the one from Fig. 2, but with the corona electrode 14 'of the previous figure is replaced by a high-voltage roller 23. This also produces like the electrode 14 'in Fig. 2 an electrical Field that the particles from the band 19 on the Substrate 10 transfers.
- roller 22 is also grounded 12 connected, as for the core 11 in Fig. 1 is the case.
- FIG. 4 shows a further device according to the invention with a roller 5 and a roller surface 6, with the electrically conductive or semi-conductive Powder particles can be transferred.
- the through the feed 2 in the Fluidizing container 1 does not introduce fluidizing air ionized.
- the electrically conductive or semi-conductive Powder is fed into the fluidizing container 4 1 introduced.
- the roller is now electric isolating and can be filled at its core or not be filled.
- the roller surface 6 is now for example by means of the "corona pincushion" 13 unipolar (e.g. negative) ionizes and then immerses in the fluidizing tank 1.
- the electrically conductive or semi-conductive powder is caused by influenza now attracted to the surface 6 of the roller 5 and there forms a powder coating 7. With another Rotation of the roller in the direction of arrow A will this coating in a transmission area transported in the "corona pincushion" 14, 14 'transfer the powder particles to the substrate 10 become.
- the "corona pincushion” 14 has a negative tension while the “corona pincushion” 14 'grounded or a positive voltage can have. Conversely, the “corona pincushion” 14 'positively charged and the “corona pincushion” 14 grounded and / or a negative voltage have.
- Fig. 5 shows a corresponding device, wherein however, a belt 19 is used as the transfer device becomes. This is as in Fig. 2 over three rollers 22, 22 '22' 'guided. Because the powder particles are electrical are conductive or electrically semi-conductive now the tape 19 electrically insulating or semi-conductive. Its belt speed is, for example 1 m / s.
- This tape is over the corona electrode 13 partially by means of bipolar air discharge or by means of unipolar and ionized Air controlled charged.
- the roller 22 is made made of electrically semi-conductive or insulating material. Due to the charge of the tape 19 on the Electrode 13 is now the electrically conductive or semi-conductive powder attracted via influenza and strikes on the surface of the tape 19 as a coating 7 down. The back of the tape will by means of a suction 24 between the rollers 22 and 22 'freed of powder.
- the transfer of the powder to the substrate 9 in the Transmission area 9 takes place as described above.
- Figs. 4 and 5 devices shown are particularly suitable for substrates with less electrical conductivity.
- Fig. 7 shows another device, here a total of six deflection rollers 22 to 22 '' '' are used become. This device corresponds to that from Fig. 2 and Fig. 3, but with the additional Deflection rolls now the band 19 above the Substrate 10 is performed. This is now done a coating of the substrate from above.
- the difference 7 is only a corona electrode 14 ("corona pincushion") provided with which the negatively polarized particles of the coating 7 can be released from the transfer belt 19.
- the electrode 14 is negatively charged. It forms such a powder coating 15 on the sheet 10.
- Fig. 9 shows another example of a vertical one Coating of a vertical substrate 10. With the pulleys 22 to 22 '' '' 'this is Transfer belt 19 guided so that it is in the transfer area 9 runs perpendicular and thus parallel to the substrate 10. The further structure of this device corresponds that in Fig. 7.
- Fig. 10 shows another device, as far as possible corresponds to that of FIG. 9.
- substrate 10 becomes here conveyed perpendicular to the transfer belt 19.
- the substrate 10 perpendicular is transported to the drawing level.
- the powder will be at the intersection between the conveyor belt 19 and the substrate 10, the powder by means of a "corona pincushion" 14, 14 'transferred to the substrate 10.
- FIG 11 shows a roller 5 with a surface 6, as shown, for example, in FIGS. 1 and 4 used becomes.
- the roller 5 has a bearing 16, the serve for example for their electrical charging can.
- the surface 6 of the roller 5 has a Pattern created by depressions, recesses or a Switch between insulating and non-insulating Areas can be trained. This leads to, that the roller powder either only in the pattern areas picks up or only to the substrate in the Provides sample areas. This is also a coating possible in the form of a pattern on the substrate.
- the electrodes 14, 14 ' form a pattern and so only in the ones they represent Areas of powder from coating 7 onto the substrate 10 to produce a patterned one Transfer coating 15.
- suitable transfer devices would be, for example, rotating disks that during a rotation of both a loading area 8, e.g. in a fluidizing chamber 1, as well as a transmission area 9 go through.
- the substrate can then either one parallel or opposite to the transfer disc rotating disc, which is the disc diameter the transfer disk in whole or in part covered.
- a band-shaped Substrate to be coated in the transfer area covering the transmission disk relatively is moved to the transmission disk.
