Definitions

  • the invention relates to a coating agent pump for conveying a coating agent, in particular a lacquer, an adhesive or a sealant.
  • the invention further comprises a cleaning method for cleaning such a coating agent pump.
  • coating agent pumps are conventionally used to convey the coating agent to be applied, which pumps can be designed as diaphragm pumps, for example.
  • the coating agent pump When changing the coating agent to be conveyed (e.g. when changing color in a paint shop), the coating agent pump must be cleaned, whereby the previously conveyed coating agent must be removed as completely as possible from the coating agent pump, since the previously conveyed coating agent would otherwise lead to contamination of the new coating agent.
  • it is known from the prior art to rinse the coating agent pump with a rinsing agent the rinsing agent being supplied via the pump inlet and leaving the coating agent pump again via the pump outlet.
  • the disadvantage of this known cleaning method for cleaning a coating agent pump is the fact that a residue of the previously conveyed coating agent and / or cleaning agent remains in the coating agent pump.
  • a coating agent change is not possible without interruption, since in addition to flushing the coating agent pump, a time passes before the new coating agent is no longer contaminated with the old coating agent and / or cleaning agent.
  • a disadvantage is the relatively long cleaning pause when changing the coating agent.
  • a coating agent pump which has a plurality of pump inlets, the coating agent pump being cleaned by introducing cleaning agent into the coating agent pump via one of the pump inlets.
  • This coating agent pump also has the disadvantages discussed above.
  • the invention is therefore based on the object of creating a correspondingly improved coating agent pump and a suitable cleaning method for it.
  • the invention encompasses the general technical teaching of effecting the cleaning of the coating agent pump not exclusively via the pump inlet and the pump outlet, but at least partially by means of a separate cleaning opening, which is provided in addition to the pump inlet and the pump outlet.
  • the cleaning opening is an ejection opening through which an ejection medium (e.g. compressed air) can be introduced into the coating agent pump in order to eject the coating agent and / or cleaning agent located in the coating agent pump from the coating agent pump, in particular via the pump outlet.
  • an ejection medium e.g. compressed air
  • the coating agent and / or cleaning agent remaining in the coating agent pump preferably leaves the coating agent pump via the pump outlet that is already present.
  • the coating agent and / or cleaning agent remaining in the coating agent pump it is theoretically also possible for the coating agent and / or cleaning agent remaining in the coating agent pump to be ejected from the coating agent pump via the pump inlet or via an additional further opening.
  • the cleaning opening is used to discharge the coating material pump remaining coating agent, so that the coating agent leaves the coating agent pump via the cleaning opening during a cleaning process.
  • the ejection medium is preferably compressed air, which is available in a paint shop, for example, and can therefore also be used without great effort to eject the coating agent remaining in the coating agent pump from the coating agent pump.
  • the cleaning opening is then a blow-out opening into which blow-out air is introduced as the discharge medium in order to blow out the coating agent located in the coating agent pump during a cleaning process, the remaining coating agent preferably leaving the coating agent pump via the pump outlet which is already present.
  • blown air used in the context of the invention is not limited to the example of compressed air mentioned above, but also includes other gaseous media.
  • the blow-out opening is connected to a compressed air line via which the blow-out air is fed to the blow-out opening.
  • the compressed air line is preferably a ring line that is already available, for example, in paint shops. Theoretically, however, there is also the possibility that the exhaust air is supplied in a different way.
  • the coating agent pump is a positive displacement pump, which is preferably designed as a diaphragm pump is. It is particularly advantageous here if the diaphragm pump is a double diaphragm pump which has two pump chambers which work out of phase with one another and therefore have a delivery flow with a relatively low pulsation. It should also be mentioned that other types of positive displacement pumps can also be implemented within the scope of the invention, such as piston pumps (for example rotary piston pumps, rotary vane pumps, reciprocating piston pumps, rotary piston pumps, etc.).
  • piston pumps for example rotary piston pumps, rotary vane pumps, reciprocating piston pumps, rotary piston pumps, etc.
  • the positive displacement pump has at least one pump chamber, the pump inlet and the pump outlet being connected to the pump chamber.
  • At least one displacer is arranged in the pump chamber, which in the preferred embodiment of a diaphragm pump is formed by a diaphragm.
  • a drive is provided in order to be able to move the displacer (e.g. membrane, piston), the drive preferably being implemented pneumatically or electrically, as is known per se from the prior art.
  • an inlet valve is arranged between the pump inlet and the pump chamber, while an outlet valve is arranged between the pump chamber and the pump outlet.
  • the inlet valve and / or the outlet valve are preferably each designed as a check valve and each have a valve body which is biased into a closed position by a closing spring.
  • Such valve constructions are known per se from the prior art and therefore need not be described in more detail.
  • the discharge port is also connected to the pump chamber to allow the in to be able to eject the coating agent located in the pump chamber by means of the ejection medium (eg blown air).
  • the ejection medium eg blown air
  • blow-out air As the discharge medium, it is advantageous if the discharge opening opens into the dead space from above, so that the blow-out air is introduced into the dead space from above. This is advantageous because the exhaust air is lighter than the liquid coating agent, so that the exhaust air displaces the liquid coating agent when the exhaust air is supplied from above.
  • the discharge opening opens into the inlet valve in order to also clean the inlet valve as optimally as possible, the discharge opening preferably opening into the inlet valve from above for the reasons described above.
  • the discharge opening preferably opens into the inlet valve at a point downstream behind the valve body, so that the discharge medium can flow into the pump chamber even when the inlet valve is closed.
  • the inlet valve preferably has a closing spring which is supported on a spring seat and presses the valve body into a valve seat in order to close the inlet valve. It is advantageous here if the discharge opening opens into the spring seat of the inlet valve in order to be able to clean this area of the inlet valve as effectively as possible.
  • the closing spring of the inlet valve is a spiral spring which is supported on the bottom of the spring seat, the discharge opening preferably opening into the floor of the spring seat, so that the discharge opening feeds the discharge medium (e.g. exhaust air) essentially coaxially to the spiral spring initiates the bottom of the spring seat.
  • the discharge medium e.g. exhaust air
  • the coating agent pump according to the invention preferably has a controllable discharge valve, which is preferably integrated into the coating agent pump or into the feed line for the discharge medium and controls the flow of the discharge medium through the discharge opening into the coating agent pump.
  • This discharge valve is preferably electrically controllable, but pneumatic or other control of the discharge valve is also possible.
  • a mixture of blown air and detergent can also be supplied via the blowout opening, in particular in pulsed form, within the scope of the cleaning method according to the invention. This optimizes the subsequent rinsing process.
  • the actual rinsing then takes place, for example, by introducing rinsing agent through the pump inlet, whereupon a mixture of the rinsing agent and coating agent residues is rinsed out through the pump outlet.
  • blow-out air can then be introduced again via the blow-out opening in order to flush out residues of the flushing agent remaining in the coating agent pump.
  • FIGS. 1 to 3 show a coating agent pump 1 according to the invention in a paint shop for painting motor vehicle body parts, the paint shop being otherwise only partially shown, since the paint shop itself can be designed in a conventional manner.
  • the coating agent pump 1 conveys the paint to be applied from a feed line 2 into an output line 3, as is known per se from the prior art.
  • the coating agent pump 1 has two pump inlets 4, 5, while the coating agent pump 1 has two pump outlets 6, 7 for connection to the output line 3.
  • the coating agent pump 1 is designed as a double diaphragm pump and has two pump chambers 8, 9, in each of which a flexible diaphragm 10, 11 is arranged as a displacer.
  • the coating agent pump 1 is driven by a pneumatic air motor, which is only shown schematically here.
  • the air motor thus comprises a piston 12 which is arranged displaceably in a cylinder 13, the piston 12 being connected to the two diaphragms 10, 11 via a piston rod 14 so that the piston position of the piston 12 also the position of the two diaphragms 10, 11 determined within the pump chambers 8, 9.
  • the piston 12 is driven pneumatically by the left or right side of the piston 12 is acted upon with compressed air, as is not shown in the drawing. In normal delivery operation, the piston 12 performs an oscillating linear movement within the cylinder 13, which is transmitted from the piston rod 14 to the two membranes 10, 11.
  • the pump inlets 4, 5 are each connected to the respective pump chamber 8, 9 via a check valve 15, 16.
  • the pump outlets 6, 7 are each connected to the respective pump chamber 8 and 9 via a check valve 17, 18.
  • coating agent is alternately sucked in via the pump inlets 4 or 5 and the check valve 15 or 16 into the pump chamber 8 or 9 and then subsequently via the check valves 17 or 18 and the pump outlets 6, 7 ejected.
  • the two pump chambers 8, 9 work out of phase, which results in a relatively low ripple in the delivery rate of the coating agent pump 1.
  • the coating agent pump 1 has a blow-out opening 19, 20 for each of the two pump chambers 8, 9, which is connected to a compressed air line 21.
  • the supply of compressed air via the blow-out opening 19, 20 enables the coating agent pump 1 to be cleaned, as will be described in detail below.
  • the blow-out openings 19, 20 are each connected to the respective check valve 15 and 16 via a blow-out valve 22, 23.
  • the check valves 15, 16 each have a closing spring 24, 25 which press a valve ball 26, 27 into a valve seat 28, 29 in order to close the respective check valve 15 or 16.
  • the spring seat of the closing springs 24, 25 here forms a dead space within the coating agent pump 1, which is not in the flow path between the pump inlet 4, 5 on the one hand and the pump outlet 6, 7 on the other, so that this dead space is difficult to clean in a conventional manner.
  • the exhaust openings 19, 20 therefore each open coaxially into a base 30 (cf. Fig. 3 ) of the spring seat, so that the blown air that is introduced is introduced essentially coaxially to the respective closing spring 24, 25.
  • the exhaust air is introduced from above, which contributes to an effective cleaning effect. This is because the exhaust air is lighter than the liquid coating agent, so that the introduced exhaust air effectively removes the coating agent from the check valves 15, 16 and thereby thoroughly cleans the coating agent pump 1.
  • a first step S2 the coating agent pump 1 is initially operated with a coating agent A.
  • the coating agent pump 1 is then first switched off in a step S2, i.e. the piston 12 is no longer driven.
  • blow-out air is then supplied via the blow-out openings 19, 20 in order to remove the coating agent A remaining in the coating agent pump 1 as completely as possible from the coating agent pump 1.
  • the coating agent remaining in the coating agent pump 1 is blown out of the coating agent pump 1 via the pump outlets 6, 7.
  • a pulsed mixture of detergent and blow-out air is supplied via the blow-out openings 19, 20 in order to optimize the subsequent flushing process.
  • flushing agent is then supplied via the pump inlets 4, 5 and ejected again via the pump outlets 6, 7.
  • blow-out air is then fed in again via the blow-out openings 19, 20 in order to flush out the rinsing agent remaining in the coating agent pump 1 through the pump outlets 6, 7.
