Definitions
- the invention relates to a piston dispenser for fluid media, in particular for supplying an electrostatically operating application device in a system for coating objects, with a) a cylinder unit that defines a cylinder space; b) a piston assembly having a piston element which is movable in the cylinder space and a working space in the cylinder space partially limited; where c) the cylinder unit has a filling opening communicating with the working space, via which fluid medium can be supplied to the working space, and a discharge opening communicating with the working space, via which fluid medium can be discharged from the working space.
- piston dispensers In order to be able to supply the application device with paint and detergent in a well-dosed manner, piston dispensers have established themselves on the market, among other things.
- a working according to the double piston piston distributor of the type mentioned is known for example from DE 10 2004 058 053 B4. There, the working space of the cylinder is filled with paint and this then fed to the application device. Rinsing of the piston dispenser and the lines leading to the application device, which is necessary before a color change, takes place by means of a rinsing agent supplied from another source.
- this can lead to relatively large paint losses and a relatively large need for washing-up liquid, which can be counteracted again, for example, by the above-mentioned pigging technique.
- both the pigging technology and piston-type dispensers operating according to the double-piston principle can satisfy, in particular, another condition which is particularly important for safety reasons: in the case of coatings with electrostatic precipitators.
- Applicable working table equipment must ensure that between application device and a lying at ground rinse aid reservoir or paint reservoir or color changer, as they are known per se, a potential separation is ensured at any time. This is achieved in known piston dispensers or the pigging technology by an insulating air layer is built up in the one or more leads from the detergent reservoir or from the ink reservoir or color changer to the piston dispenser, wherein the piston dispenser itself is at the potential of the application device.
- an insulating air layer is present in particular in an insulation space between two pistons. If, however, not all electrically conductive material, be it paint or detergent, is reliably displaced from the line, or such conductive material passes into the insulation space due to a leak that is not immediately detected in the piston dosing device, electrical over-blows can occur.
- the piston dispenser can work favorably with a monoblock piston arrangement and the piston element of the piston arrangement can be formed by a piston of a piston unit which can be driven externally.
- the piston element of the piston arrangement is formed by a piston which is movable independently in the cylinder space and the piston arrangement furthermore comprises a piston unit which can be driven externally and which acts on the side of the independently movable piston remote from the working space arranged and can be brought into operative connection with this.
- the piston dispenser thus operates with a double piston arrangement.
- the independently movable piston is designed as a floating piston, no separate drive is required for this.
- the floating piston can be driven from one side by fluid medium which can flow into the working space via the filling opening, and from the other side by means of the piston unit in one or the other direction in the cylinder space.
- the piston unit can be locked releasably in at least one position with the cylinder unit, so that the cylinder unit is carried along by the piston unit during its movement.
- the movement of the cylinder unit can be advantageously achieved from its filling position into the delivery position and optionally back, by the piston unit being moved by its drive.
- the piston unit and its piston do not move in the cylinder space.
- the cylinder unit can be locked in its filling position and / or in its dispensing position with the connection arrangement.
- the respective position of the cylinder unit can be secured and the dissolved piston unit can be moved relative to the cylinder unit.
- a secure locking is advantageously achieved by compressed air-actuated locking elements which occupy a locked state without compressed air supply under bias and a release state with compressed air supply.
- the involved components can only be unlocked from each other in this case, if the one or more associated locking elements are specifically supplied with compressed air. This reduces the risk of unintentional unlocking.

- the cylinder unit 20 the detergent S to the discharge port 80, from where it gets to the application device 82 and cleans it.
- valves V2 and V4 are closed again and the piston unit 32 is moved by means of the drive 42 back into its locking head position
- the locking plugs 86 in the head connection unit 78 are supplied with compressed air and release the cylinder unit 20 as a whole.
- the piston unit 32 is moved by means of the drive 42 in the direction of theticianan gleichiser 68. In doing so, it again carries with it the cylinder unit 20, which is thus moved back from its delivery position into its filling setting, and the filling and dispensing process can again be carried out with the starting situation shown in FIG.
- FIG. 10 shows a part of a modified piston extruder 10 in which the only difference is the angled piston Channel 64 in the foot base 16 does not have its own mouth opening to the working chamber 52 of the cylinder unit 20 leads, but rather opens into the channel 56.

- Floating piston present, so that the working space 52 is formed between the base 16 of the base cylinder unit 20 and the piston 38 of the piston unit 32, wherein the volume of the working space of the position of the piston unit 32 relative to the cylinder unit 20 depends.
- a piston assembly is thus formed in this embodiment only by the piston unit 32.
- the piston 38 of the piston unit 32 in this case has no through-channel and the locking portion 36 of the piston unit 32 now has the same cross-section as the piston rod 34th
- the piston unit 32 has a second locking region 92 with a latching depression 92a in the piston rod 34, which is arranged at a distance from the first locking region 36 with the latching depression 36a.
- the latching depression 92a is positioned on the piston rod 34 in such a way that it comes to lie in front of the latching nose 44 of the locking plug 46 when the piston unit 32 assumes a position in which the piston 38 bears against the pedestal 14. These positions ment defines a lock foot position of the piston unit 32.

- the application unit 82 and the flushing agent source 72 are also shown only in FIG. 11.
- the channel 64 may open into the channel 56, as illustrated in FIG.
- the modified piston feeder 10 works as follows:
- valves VI and V3 are opened, the lock of the piston unit 32 is released by the locking plug 46 and the piston unit 32 is moved by means of the drive 42 in its locking-Kop position.
- flushing agent S flows out of the flushing agent source 72 into the working space 52 of the cylinder unit 20.
- the cylinder unit 20 is released from the bottom connection unit 68 and moved to its discharge position by the piston unit 32 is moved accordingly, thereby leading the cylinder unit 20 with it.
- the piston dispenser 10 compared to the piston dispenser 10 fewer intermediate steps are required, the potential separation between source 72 and application device 82 is always ensured by the spatial separation of the cooperating opening and connection components.
- the stroke that the piston unit 32 must be able to travel is considerably less than that of the piston dispenser 10 '. Accordingly, the piston rod 32 and / or the coupling shaft 94 must be longer in the piston dispenser 10 'than in the piston dispenser 10. The piston dispenser 10 should therefore be made more compact than the piston dispenser 10' with otherwise identical dimensions.
- the detergent S can be pressed into the application system with high pressure, which can be greater than 10, whereby a high cleaning performance can be achieved.
- the linear movement of the piston unit 32 can be precisely monitored and controlled by known techniques, so that a high-precision metering of the quantities of liquid dispensed is possible.
- piston dispensers 10, 10 'explained above are can be used to provide the application device 82 with paint, so several piston dispensers 10, 10 'can be combined to form an application system. At least one of these juxtaposed piston feeders 10, 10 'may then be used to flush the system.
- Each other piston dispenser 10, 10 'can each be assigned a paint reservoir with a paint of a particular color, it is advantageous if each two piston dispensers 10, 10' are fed from a paint reservoir and operated according to the well-known dual principle. In this case, the application process for two objects, which are to be successively coated with the same color, can be continued rapidly, since one piston dispenser 10, 10 'can be filled with the paint, while the other piston dispenser the paint for application of the first Object.
