Definitions
- the invention relates to an insulation device and a coating system for coating objects, wherein the coating system comprises an electrostatically operating application device with a dispensing device, by means of which a coating material can be dispensed, and at least one reservoir for coating material, via an inlet line with an input valve means and over a supply line is connected to the dispensing device.
- the coating system comprises an electrostatically operating application device with a dispensing device, by means of which a coating material can be dispensed, and at least one reservoir for coating material, via an inlet line with an input valve means and over a supply line is connected to the dispensing device.
- Such coating systems for example, in the automotive industry, articles such as vehicle bodies or body parts are coated by means of the electrostatically operating application device.
- the coating material for example a lacquer
- the coating material is dispensed by the dispenser and exposed to an electric field. In the electric field, the dispensed coating material is ionized and transported by means of electrostatic forces to the object to be coated.
- the object is at ground potential.
- Such an application device may be, for example, a high-rotation atomizer, in which the delivery device comprises a rotating bell cup, from which smallest droplets of paint are thrown off. The resulting paint mist is ionized in the electric field and thereby transported to the object to be coated.
- the input valve device may, for example, be a so-called color changer, which is fed from ring lines with different media. If, for example, the color shade is changed between two coating operations, the dispenser must be supplied with another coating material. To be able to perform such a color change time efficient, are in modern coating systems often two supply lines provided. Thus, during a coating operation, the application device can be fed from a supply line with a first coating material and at the same time a second supply line can be prepared with a second coating material. This reduces the color change time.
- the corresponding line sections are cleaned with a rinsing agent and then blown dry with compressed air to build an electrical insulation route.
- the insulation device according to the invention is provided for a coating system for coating objects, wherein the coating system is an electrostatically operating application device with a dispensing device, by means of which a coating material can be dispensed, and at least one reservoir for coating
- the supply container is connected via an inlet line to an input valve device and via a supply line to the delivery device.
- the isolation device comprises a channel with a movable in the channel RäumMech.
- the reaming body has an electrically insulating material and is movable between a parking position and an isolation position.
- the broaching body is movable by means of a fluid pressure and designed such that it frees an inner circumferential surface of the material during a movement from the parking position to the isolation position or from the isolation position to the parking position, so that an electrical insulation path exists between the reservoir and the input valve device can be trained.
- the broaching body is moved back and forth between the parking position and the isolation position, an electrical insulation route can already be built up by this broaching movement together with the electrically insulating material of the broaching body.
- the movement of the broaching body can advantageously be generated exclusively by a fluid pressure.
- the fluid pressure may be transmitted to the reaming body, for example, by direct contact between the fluid and the reaming body or by indirect contact such as by a pig body contacting the reaming body and itself exposed to fluid pressure.
- the broaching body has an insulation section for electrical insulation and a line section for a material line.
- the broaching body in a first position for example the insulation position
- the insulation section can represent an insulation path and thus form a potential separation.
- the broaching body with the line section can allow a passage, for example of coating material, through the broaching body.
- the broaching body has a longitudinal axis in the direction of movement and isolation section and line section are arranged along this longitudinal axis.
- the broaching body has a longitudinal axis in the direction of movement and isolation section and line section are arranged along this longitudinal axis.
- the isolation section defines an isolation space in the channel. If the broaching body moves into the isolation position, on the one hand the inner lateral surface of the channel can be cleared of possibly conductive material. On the other hand, the broaching body forms with its insulating section in the isolation position within the channel an insulation space, which enables a potential separation.
- the insulation space can be filled with an insulating material.
- insulation material for example, air, ester or vegetable oils, Vaseline or (C10-C21) alkanesulfonylphenyl ester, a marketed under the trade names Mesamoll and Mesamoll II mixture of various alkylsulfonic acid esters of phenol, can be used.
- the line section can have a coating material line. It is thus possible to guide coating material through the broaching body, in particular through the coating material line. This can be provided in particular in the parking position of the broaching body. In this position, it may be provided that the broaching body, for example, provides no potential separation.
- the coating material line has a first line connection lying radially to the direction of movement and a second line connection lying on an end face of the reaming body.
- It can the broaching, for example, have a cylindrical basic shape.
- the first line connection can be arranged in such a basic shape, for example on the outer circumference of the cylindrical basic shape.
- coating material can be supplied to the broaching body via the first line connection, which is accessible on its outer circumference, and can be delivered again via the second line connection situated at the end.
- the conveying direction can also be reversed.
- another fluid which requires potential separation, to be supplied and discharged via the first and the second line connection.
- the radial line connection in the isolation position allows a line connection between the coating material line and the feed container and / or the end-side line connection a line connection between the coating material line and the dispenser.
- This allows in the isolation position, a supply of, for example, coating material over the line section of the broaching, while the isolation section allows potential separation between the application device and the rest of the coating system.
- the object is also achieved by a coating system for coating objects according to claim 8.

After the end of the coating process in the first supply line 20, the coating system wetted with the coating system of the first supply strand 20 is rinsed with detergent and the remaining coating material pushed back into the conduit 48. If the rinsing agent stored in the piston dispenser 34 is used for this purpose, this first flushing process can still be carried out with the high voltage applied.
- the high voltage is turned off and the Farbap infectionssorder comprising the discharge line 18, the wetted in the output valve unit 24 lines and valves, the supply line 36, the channel 104 of the insulating device 100, the coating material discharge line 52 and the corresponding line sections of the metering -Ventiltechnik 46 with further addition of detergent, for example, from the working lines 54, 38, cleaned.
- the valves 465, 463, 462 of the metering valve unit 46, the valve 521 of the discharge line 52 and the valves 241, 242 of the output valve unit 24 are opened.
- the distance of the supply line 20 used for the previous coating is blown free. This is shown in FIG.
- the valves 463, 465, 462 of the metering valve unit 46, the valve 521 of the discharge line 52 and the valves 242, 243 of the output valve unit 24 are opened, the valves 461, 464 of the metering valve unit 46 and the valves 241 , 244, 245 of the output valve device 24 are closed.
- the compressed air can be supplied or removed, for example, via the lines 54, 38.
- the filling process of the piston dispenser 35 with coating material and the insulating space 121 with insulating medium is completed in the second supply line 21.
- the Räumköper 103 of the isolation device 101 of the second supply line 21 is already in the isolation position and the second coating material is already pressed to the output valve unit 24.
- the boundary runs through the emptied supply line of the first supply line 20, the empty working line of the ventilation connection of the isolation device 101 of the second supply line 21, the actual isolation space of the isolation device 101 (represented by an ellipse-shaped border) and through the empty second working line 55 of the second supply line 21 , which connects the color changer 26 with the metering valve unit 47 of the second supply line 21 (also represented by an elliptical border).
- a flushing of the piggable section 481 and optionally the inlet line 48 can take place in the supply line 20.
- the flushing medium via the line 483 with the valve 485 open, the pig 482 can be pushed back and the inlet line 84 can be cleaned.
- the two-part design of the paint supply system results in low ink losses and a short color change time due to the mutual fillability of the supply strands 20, 21.
