Definitions
- the present invention relates to a painting device according to the preamble of claim 1.
- Such painting devices are known from the market. They use a so-called “pig” to clean the connecting device (generally a hose) between the paint changing device and the gun unit.
- This is an element, e.g. a ball which e.g. pressurized is moved by the connecting device.
- the connecting device can be cleaned, if necessary with the addition of a cleaning agent.
- the pig is in a pig station in the known painting devices
- Pistol unit area Another pig station is located at the end of the color changing device facing the connecting device (this is understood to be a device which can optionally connect the spray gun with one of several pre-conveyed paint colors which are usually under pressure).
- the paint still in the connecting device is first withdrawn with a pump.
- the pig is then moved from its pig station located at the gun unit to the pig station of the color changing device and the connecting device behind the pig with air and a cleaning agent, e.g. a paint thinner, rinsed.
- Newt returned to its resting position in the newt station there.
- a disadvantage of the known painting device is that a certain amount of residual paint remains in the color changing device at the end of the cleaning process. At the start of a new painting process, the gun therefore first comes out of paint contaminated by residual paint. Therefore, the user must first spray some paint before he can start the actual painting process. This increases the paint consumption, which is perceived as bad, especially from an environmental point of view.
- the object of the present invention is therefore to develop a painting device of the type mentioned at the outset in such a way that the amounts of paint wasted in the cleaning process and the amounts of residual paint present in the system after a cleaning process are significantly reduced.
- the pig station assigned to the color changing device is located at the end of the color changing device facing away from the connecting device, the pig can be located

- the color changing device where it would block their entrance for the pig, but is arranged in the area of the gun unit.
- the entrance from the connecting device to the color changing device for the pig is free, so that the pig can easily move into and through the color changing device.
- a single sensor is sufficient to control the closing process of the paint valve device and the residual paint valve device.
- FIG. 10 shows in a schematic block diagram a painting device, which is designated overall by reference number 10 (in the block diagram, fluid-carrying lines are drawn with double lines for better identification).
- It comprises a gun unit 12, a stationary unit 14, a connecting device connecting the gun unit 12 to the stationary unit 14, which is designed here as a hose 16, and a controller 18, the functions of which will be explained in detail later.
- a gun 20 includes a spray nozzle 22 which is directed to a container 24 in the figure.
- a paint pressure regulator 26 is connected to the gun 20. This is in turn connected via a valve 28 to a paint channel 30, which is part of the hose 16.
- the valve 28 has an open and a closed position and is controlled by the controller 18 via a line 31.
- the gun 20 is mechanically connected to a switch 32, which provides the control 18 with an input signal via a line 34. As shown below, the switch 32 triggers a cleaning process.
- the gun unit 12 further comprises a pig station 36, in which a pig, not shown in the figure, has its starting position.
- the pig station 36 is connected at one end to the paint channel 30 and at its other end to a valve 38. This is controlled by the control 18 via a line 40 and connects the pig station 36 to a secondary channel 42, which is also part of the hose 16.
- a movement sensor 44 is arranged in the area of the exit of the pig station 36 to the lacquer channel 30, which emits a signal to the control 18 via a line 46 when the pig moves past it.
- this comprises a color changing device 48, which is essentially an elongated cylindrical chamber.
- the color change device 48 is connected to the paint channel 30 at its end on the hose side. At this At the end there is also a movement sensor 50, which emits a signal to the control 18 via a line 52 when the pig moves past it.
- Valves 54, 56 and 58 are arranged on the side of the color changing device 48 and can optionally connect the interior of the color changing device 48 to lacquer feeding devices 60, 62 and 64. Paint supply lines 61, 63 and 65 lead from the paint supply devices 60, 62 and 64 via the paint valves 54, 56 and 58 to the color changing device 48. The corresponding openings of the supply lines 61, 63 and 65 in the color changing device 48 are identified by the reference numerals 55, 57 and 59. The valves 54, 56 and 58 are controlled by the controller 18 via lines 66, 68 and 70.
- the color changing device 48 is connected to a pig station 66, in which the pig has its end position.
- a movement sensor 68 is arranged between the pig station 66 and the color changing device 48, which emits a signal to the control system via a line 70 when the pig moves past it.
- the pig station 66 At the end of the pig station 66, which faces away from the color changing device 48, the pig station 66 is via a residual paint channel 72 and a residual paint valve 74 connected to an outlet opening 76, which in the present exemplary embodiment lies above a residual paint container 78.
- the residual paint valve 74 is controlled by the control 18 via a line 80.
- the pig station 66 is also connected at its end facing away from the color changing device 48 to a valve 82 which is controlled by the controller 18 via a line 84. At its other end, the valve 82 is connected to a compressed air source 86.
- a container 90 with a cleaning agent e.g. Paint thinner, which in turn is fluidly connected to the secondary channel 42.
- the painting device 10 works as follows:
- the pig In normal painting operation, the pig is located in the pig station 36 of the gun unit 12.
- the valve 38 in the gun unit 12 is closed, as are the valves 74 and 82 behind the stationary pig station 66.
- at most one of the paint valves 54, 56 and 58 is open , In the present case it is assumed that the paint valve 56 is open and the paint valves 54 and 58 are closed.
- paint from the paint feed device 62 passes through the paint supply line 63 through the paint valve 56 and via the mouth 57 into the paint changing device 48 and from there via the paint channel 30 through the opened valve 28 in the gun unit 12 through the paint pressure regulator 26 into the gun 20.
- the paint is sprayed through the nozzle 22.
- the cleaning agent in the paint channel 30 is pressed by the pig through the opened valve 28, the paint pressure regulator 26 and the gun 20 to the spray nozzle 22 and exits from it into the container 24.
- the controller 18 issues.
- the controller 18 closes the valve 82 again, whereby the cleaning process is completed.
