If the at least one channel is straight, it can be traversed by a pig, which pushes out the medium present in the channel for reuse and cleans the channel.
- the channels in the applicator between the charging shaft and the tank are relatively short, so that when the medium is changed (color change) only small residues of the old medium remain in this area. which can be removed with a small amount of cleaning agents before the tank is refilled and are insignificant in this respect.
- the loading shaft preferably has a loading channel, a return channel, which can also take on a flushing function, and a flushing channel.
- the loading channel is preferably used to fill the tank.
- the return channel makes it possible, in the event of a color change, to recover the color that is still in the charging channel and to flush an annular channel in the process.
- the flushing channel is used to clean the device.
- the invention provides that the loading shaft consists of a central loading tube, a middle tube and an outer tube, where the loading channel from the loading tube, the return channel from an annular gap between the loading tube and the middle tube and the Flushing channel is formed by an annular gap between the middle tube and the outer tube.
- the remote from the loading station distal end of the charging shaft has a valve system that is introduced into the distributor in the applicator.
- the distributor has an inlet channel and a tank channel , whereby in a first switching Se ttings of Ventilsys tems the loading channel to the return channel, in a second switch S of the loading channel tellung with the tank passage, and in a third switching Se ttings the return channel and the loading channel are locked.
- the loading tube can be displaced in the longitudinal direction with respect to the central tube.
- the distal end of the loading tube is closed, but has lateral openings that connect the loading channel with the return channel, with seals in front of and behind the openings and the inner surface of the central tube has a circumferential bypass, preferably in the form of a bypass groove having.
- the tank has an integrated heater and / or consists of a transparent material.
- the last feature enables the color of the medium to be determined using an intelligent camera.
- the applicator device is an atomizer device, which is preferably implemented by an atomizer bell or a paint-air-nozzle ring.
- the applicator device has a print head with a plurality of nozzles.
- Such novel applicator devices allow the medium to be discharged with sharp edges, so that in particular an overspray is largely, if not entirely, avoided.
- FIG. 1 shows a schematic representation of a device with an atomizer having a tank and a charging station, wherein a valve system is in a second switching position, in which the tank can be filled from the La destation,
- Fig. 2 shows an enlarged view of the distal end of the shaft, the valve system being in the second switching position
- Fig. 3 shows an enlarged view of the distal end of the shaft, the valve system is in a third switching position, and
- FIG. 4 shows an enlarged illustration of the distal end of the shaft, the valve system being in a first switching position.
- FIG. 1 A first figure
- the device consists of an atomizer 1 and a charging station 2.
- the atomizer has an integral tank 3 with a sliding piston 11 which is actuated by a sliding medium originating from a dosing cylinder 4, the dosing cylinder 4 or one driven by a Spindelmo tor 12
- Dosing pump 5 defines an exact Austra supply rate.
- the tank 3 has an integrated heating coil 10 to heat the medium (the paint) to a predetermined processing temperature.
- To the tank includes a first and a second distributor block 6, 7 existing distributor, which is equipped with various valves to control the atomizer.
- an atomizer device which in this embodiment is designed as an atomizer bell 8, behind which there are paint nozzles 9, which are fed from the tank 3 with the corresponding valves in the distribution blocks 6 and 7 with the medium (paint) are supplied.
- the rapidly rotating atomizer bell 8 ensures that the colored lacquer is evenly z. B. is discharged onto a vehicle body.
- a lacquer-air-nozzle ring can also be used instead of an atomizer bell.
- the charging station 2 consists of a housing 15 with a loading bay 16 into which the atomizer head with the atomizer bell 8 can be inserted.
- the atomizer is completely cleaned on the outside and at the same time the tank 3 is filled with paint.
- a charging shaft 17 of the charging station 2 protrudes centrally into the charging bay 16 and is guided through a longitudinal channel in the atomizer bell 8 to the distributor block 7.
- the loading shaft 17 consists of a loading tube 20, a central tube 21 and an outer tube 22.
- the inner tube has a loading channel 23.
- an annulus that functions as a return duct 24 or, depending on the circuit, also serves to flush
- another annulus which is used as Flushing channel 25 acts.
- the loading tube 20 is extended back ⁇ rtig beyond the charging station 2 and is ge leads to a paint changer 30, which allows the loading tube 20 to be loaded with different colors.
- a pig station is located at both ends of the loading tube 20.
- the pig station at the proximal end of the loading tube 20 is denoted by 31, the one at the distal end by 33.
- a spherical pig 34 is shown, which is moved by means of a pushing medium from this position to the pig station 31 at the proximal end of the loading tube is displaceable.
- an adjusting device for moving the loading tube 20 In the housing 15 of the loading station 2 there is also an adjusting device for moving the loading tube 20. This consists of a cylinder piston 32, which is connected to the loading tube 20 and is in three different positions, which are identified with Pos. 1, Pos. 2, Pos. 3 are designated, can be adjusted.
- the head of the loading shaft 17 forms a valve 40, which is shown symbolically in FIG. 1, but which is actually implemented by the configuration of the head of the loading shaft 17 described below.
- the loading tube 20 is closed at its distal end, but has sloping lateral openings 35 between the loading channel 23 and the outer surface of the loading tube 20, the mouth of the opening on the outer surface to the proximal End of the loading tube is directed.
- a ring seal 36, 37, and a bypass groove 38 is formed in the inner surface of the central tube 21.
- the diameter of the tube or the man can be enlarged from the sealing area to the proximal end of the loading shaft.
- FIG. 4 the first switching S position or lower position of the loading tube 20 (Item 1 according to FIG. 1) is shown, in which the just mentioned one seal 36 rests against the inner surface of the central tube, while the other seal 37 lies in the area of the bypass groove 38. Thereby are the loading channel 23 and the return channel
- the flushing channel 25 is in the second distributor 7 always with egg nem inlet channel 42 (see Fig. 2) in the distributor head 7 a related party, which via valves in the distributor blocks 6, 7 with
- Air or solvent can be charged to clean the assembly. This happens when the atomizer 1 is docked in the charging station 2 and is used to prepare or when filling the new paint into the charging tube 20 or into the tank 3 of the atomizer 1.
- the description of the exemplary embodiment is not intended to limit the invention to an atomizer. Rather, instead of an atomizer device, the invention can also be implemented with a print head having a plurality of nozzles, which allows the medium to be dispensed with sharp edges.
