Definitions
- the invention generally relates to the technical field of spray coating of objects or items.
- this relates in particular to a spray gun for preferably manual spray-coating of objects with powdered coating material.
- the invention is not limited to this, but can also be used for spray guns for automatic spray-coating of objects, in particular for spray-coating objects with liquid coating material.
- the invention relates to a spray gun, in particular a powder spray gun, the spray gun having a handle part and a gun barrel connected to the handle part.
- Spray guns of this type are already known, at least in principle, from the prior art.
- publication EP 0 383 030 A1 relates to a spray gun for spray-coating objects with coating powder.
- the spray gun known from this prior art has a grip part and a gun barrel connected to the grip part.
- spray coating objects it is important to achieve a coating that is as homogeneous and uniform as possible on the object to be coated. In the case of complex objects in particular, which have undercuts, openings or irregular surfaces, this goal can often only be achieved with great effort.
- the experience and skill of the operator guiding the spray gun is particularly important for objects to be coated in order to be able to achieve the most perfect (optimal) coating result possible.
- the experience of the spray gun operator is based on "knowing" how to guide the manual spray gun relative to the object to be coated in order to maintain an even distance between the application nozzle of the spray gun and the surface of the object to be coated.
- the object of the invention is to create a lighting device by which a spray gun can be supplemented as required, in particular also in order to retrofit commercially available spray guns with a corresponding lighting device. On the other hand, this lighting device should not impair the easy handling of the spray gun.
- the invention relates in particular to a spray gun, for example a powder spray gun, the spray gun having a handle part and a gun barrel connected to the handle part.
- the spray gun also has an illumination device for continuously or as required illuminating and/or illuminating at least one area of an object to be coated with the spray gun.
- the lighting device is detachably and in particular exchangeably connected to the spray gun.
- the lighting device has a ring-shaped light source carrier with at least one light source, in particular in the form of an LED.
- the bulb support extends around a downstream portion of the gun barrel on which it is radially supported.
- the lighting device is suitable for retrofitting a conventional spray gun accordingly.
- the ring-shaped illuminant carrier provides a ring light that allows optimal lighting and/or illumination of at least one area of the object to be coated. Due to the fact that the illuminant support extends around a downstream area of the gun barrel, on which it is radially supported, no structural changes need to be made to the spray gun in order to equip it with the lighting device.
- the gun barrel of the spray gun has a gun shaft with a nozzle on its downstream end region is arranged, over which the coating material (such as coating powder) is atomized during the spraying process.
- the nozzle is preferably interchangeably connected to the pistol shaft with the aid of a union nut that is in particular at least partially sleeve-shaped.
- the area on which the ring-shaped illuminant carrier is supported is an area of the union nut and in particular a sleeve-shaped area of the union nut.
- the area on which the ring-shaped illuminant carrier is supported is an area of the union nut and in particular a sleeve-shaped area of the union nut.
- the pistol barrel and in particular the union nut can have at least one indexing means, which in particular interacts in a form-fitting manner with preferably at least one counter-indexing means of the illuminant carrier, which is designed to be complementary to the indexing means, in such a way that in particular a rotational alignment of the illuminant carrier with respect to the pistol barrel is effected.
- the ring-shaped illuminant carrier can be displaced in the axial and/or radial direction relative to the pistol barrel and can be locked in the selected position by suitable positioning means.
- At least one connecting web is provided, which preferably extends in regions in the longitudinal direction of the gun barrel, which is connected on the one hand to the illuminant carrier and on the other hand is preferably detachably connected or can be connected, in particular to an upstream area of the gun barrel, with the at least one connecting web being outside of the gun barrel and at least partially carries the bulb holder.
- the at least one connecting web forms an electrical connection between an electrical connection, in particular on the upstream area of the gun barrel, and the at least one illuminant of the illuminant carrier.
- the electrical connection can, for example, a electrical line extending at least in regions through the at least one connecting web.
- the connecting web can thus be of tubular design, at least in certain areas.
- the connecting web can also consist of an electrically conductive material which forms the electrical connection.
- the electrical connection in particular in the upstream area of the pistol barrel, is electrically connected, in particular via an electrical line running at least in some areas through the grip part, to an adapter preferably provided in the lower area of the grip part.
- a plurality of lamps in particular each in the form of an LED, is preferably provided, with the lamps being distributed in particular in an equidistant manner around the ring-shaped lamp carrier and aligned in the direction of the downstream end region of the pistol shaft.
- the alignment and/or the focus of the lighting or illumination effected with the lighting means or the at least one lighting means is possible on different areas of the object to be coated.
- the focus of the illumination can preferably also be designed to be adjustable (for example analogous to the focusing of a flashlight) in order to optimally illuminate areas of the object to be coated that are at different distances.
- the lighting can also have a fixed focus or can be focussed in raster steps in order to signal the optimum distance from the spray gun to the object to be coated to the operator of the spray gun—also and particularly during vocational training.
- a scavenging air device is provided for the selective or required flow of compressed air around the illuminant carrier, in particular in order to keep the at least one illuminant of the illuminant carrier free of coating material. Since compressed air is already required to operate the spray gun, and this usually is already fed to the spray gun, the implementation of such a scavenging air device is possible without much effort.
- this is designed for the electrostatic spray coating of objects and for this purpose has at least one charging electrode in order to transfer electrostatic charge to the coating material sprayed or to be sprayed with the spray gun.
- the charging electrode has an electrical potential which differs from the electrical potential of the object to be coated in such a way that the charged coating material is electrostatically attracted to the object to be coated.
- the coating material can be positively or negatively electrostatically charged either immediately before the outlet opening, in particular nozzle opening, of the spray gun or after the outlet opening.
- the at least one charging electrode used for this purpose is connected to an electrical high voltage in the range between 40 kV and 140 kV.
- the object to be coated has a different electrical potential, preferably ground potential.
- the atomized coating material moves along electric field lines which are generated by the high voltage between the charging electrode and the object to be coated. After a thin layer of coating material has formed on the object to be coated, this layer repels subsequent coating material particles due to its electrical charge, because these are electrostatically charged in the same way. As a result, only a limited layer thickness can be produced on the object to be coated in one operation.
- the electrostatic attraction of the object to be coated is different in particular at corners and edges as well as at openings of this object than on larger flat surfaces. Corners and edges are usually coated worse or less thickly than adjacent larger surface areas.
- the Coating material particles fly around the outer peripheral edges and around the edges of openings of the object to be coated under the action of the electrostatic field and are then attracted to the back of the object due to the electrostatic attraction force, so that the back of the object to be coated is also coated here. This can be referred to as 'electric wraparound'.
- a counter-electrode which extracts free ions from the sprayed coating material flow, can improve the surface quality and the ability of the coating material to penetrate depressions in the object to be coated. Furthermore, a thicker layer of coating material can be applied to the article to be coated in one spray operation without excessive coating material particles bouncing off the article or being electrostatically repelled. In particular, an "orange heap"-like layer surface can be avoided.
- the spray gun has at least one counter-electrode arranged in the vicinity of the charging electrode, which is connected to a different electrostatic potential than the charging electrode, so that at least part of the electrostatic potential generated during the electrostatic charging of the coating material absorbs free ions.
- the ring-shaped illuminant carrier carries the at least one counter-electrode.
- the illuminant carrier thus has a dual function: on the one hand, the illuminant carrier serves to accommodate at least one illuminant in order to illuminate or illuminate at least one area of the object to be illuminated continuously or as required. On the other hand, the illuminant carrier serves to accommodate at least one counter-electrode in order to absorb at least some of the free ions generated during the electrostatic charging of the coating material and thus to improve the coating result.
- the ring-shaped illuminant carrier carries the at least one counter-electrode
- the at least one connecting web extending in the longitudinal direction of the pistol barrel also serves to form an electrical connection between a potential connection and the at least one counter-electrode.
- a plurality of counter-electrodes preferably in the form of needle electrodes, protrude from the ring-shaped lighting means carrier.
- a distance between the charging electrode and the counter-electrode should be smaller than a distance between the charging electrode and the object to be coated.
- the distance between the charging electrode and the counter electrode should be 1/3 to 1/2 of the distance between the charging electrode and the object to be coated.
- the counter-electrode is preferably arranged at a distance from a cloud of coating material atomized with the spray gun, the distance between the counter-electrode and the cloud of coating material being smaller than a distance between the charging electrode and the object to be coated.
- the invention relates not only to a spray gun with a corresponding lighting device that can be connected to the spray gun in an exchangeable manner, but also to a lighting device as such for a spray gun, in particular a spray gun of the type mentioned above.
- the lighting device is therefore used for continuous or required lighting and/or or illuminating at least a portion of an object to be coated with the spray gun.
- the lighting device can be connected to the spray gun in a detachable and, in particular, exchangeable manner and has a ring-shaped illuminant carrier with at least one illuminant, in particular in the form of an LED, with the illuminant carrier being designed so that it can extend around a downstream area of the gun barrel of the spray gun and can be supported radially on this.
- the lighting device preferably has at least one connecting web, which serves to support the ring-shaped illuminant carrier when the lighting device is installed, the at least one connecting web also serving in particular to supply the at least one illuminant of the illuminant carrier with electrical energy.

- the coating material 21 to be sprayed is fed to the spray gun 1 from a powder source not shown in the drawings.
- the flow of the coating powder entrained in the air is fed from a coating material supply line through an adapter 14 provided at the lower region of the handle part 2 into a coating material line running through the handle part 2 .
- Connections 15 for compressed air and connections 16 for electrical energy are also provided at the lower end area of the handle part 2 .

- the upstream end region of the connecting web 10 can be connected to the electrical connection 17, which is provided, for example, in the rear shell of the spray gun 1.
- the electrical connection 17 is electrically connected to an adapter 14 preferably provided in the lower area of the handle part 2 or to a connection provided in the lower area of the handle part 2 , in particular via an electric line running at least in some areas through the handle part 2 .
- the article 20 to be coated is typically carried by a conveyor and transported through a spray coating booth.
