Definitions

  • the invention relates to an inking system according to the preamble of claim 1.
  • HVLP systems high-volume, low-pressure
  • the paint is atomized at low air and color pressure in a known manner.
  • the air blower and the paint pump are housed either in the gun unit or alternatively in a base station. The air and the paint are brought together in the spray head and atomized the paint in a known manner.
  • the color transport takes place via a in the Base station provided color pump, which sucks the paint from a paint bucket or other reservoir and promotes an optionally several meters long paint hose to the paint spray gun or a paint roller or the like.
  • a paint application tool such as a paint roller, paint brush or paint spray gun.
  • color pressures of 2 bar to 8 bar are necessary in order to overcome the pressure drop occurring in the paint hose.
  • the actual spraying in the paint spray gun with a relatively low color pressure of, for example, only about 0.3 bar to 0.4 bar is performed.
  • the spraying should be done on the spray head itself at a reasonably lower pressure to avoid uncontrolled paint leakage, called "spitting" when opening a needle valve on the spray head.
  • this realized results in a non-uniform ink application due to fluctuating discharge amounts of atomizable paint on the spray nozzle.
  • this effect is avoided by switching on and off the color promotion according to the amount of ink to be dispensed.
  • this requires complex and short-term switching operations, which make the corresponding equipment complicated, prone to failure and expensive. Paint rollers or paintbrushes also need to be supplied with color continuously, without giving off any material pulses of color when opening a valve.
  • a color input line is to be understood as a line which is provided for supplying ink to a color dispensing device, for example to a spray gun, and is connected upstream of a pressure regulator.
  • a color input line can be understood in the context of the invention, a paint hose.
  • a color delivery line is understood as meaning a line which is connected downstream of a pressure regulator and is provided for supplying ink to the outlet of a color dispensing device, for example a spray gun.
  • the ink discharge line is disposed within a paint dispenser, such as a spray gun.
  • the invention has for its object to provide an inking system, which allows control of the color printing both in the base station and in the spray gun to produce a uniform application of paint due to a constant working pressure as possible in the spray gun or the like.
  • the invention relates to a paint application system with a transportable paint roller, paint brush, color pad, etc. or a portable paint spraying device or paint spray gun with blower for color output via a spray head with paint nozzle and needle valve. Further comprising a stationary during the operation for inking base station with connection to a color supply, the base station having a paint pump for the suction of color from the ink supply and promotion of color by means of pressure, and wherein the base station with the paint roller, etc. or the Farbsprüh adopted on a Color hose is connected and supplies the paint roller etc. or the Farbsprüh worn with color.
  • the paint roller etc. or the paint spraying device comprises a pressure reducer / pressure regulator connected downstream of the paint hose, which regulates the color print in a color delivery line to a paint roller etc. or a paint spray head to a substantially constant color print, which is lower than a color print in the paint tube;
  • Color pump in the base station is assigned a pressure monitor to monitor the required color pressure at the paint pump side end of the paint hose.
  • the inking system provides the necessary working pressure of the ink in the paint hose via the paint pump and the pressure monitor arranged there.
  • the transportable working device for example the paint roller, paint brush, color pad or a paint spraying device via the pressure reducer / pressure regulator, ensures that only the working pressure necessary for the controlled and quality-optimized processing of the ink is available for the ink delivery.
  • This interplay allows a color feed pressure in the paint tube to be provided by the paint pump independently of the process color print.
  • the paint pump does not run continuously even during operation, but instead provides the system with color printing within certain limits, which reduces pump wear and / or protects pressure-affected connection areas.
  • a first control loop for controlling the color printing at the output of the ink pump and a second control loop for controlling the color printing is provided on the color delivery line.
  • the aim is to set a substantially constant ink discharge pressure in a paint delivery line on an ink dispenser, for example a paint spray gun, a paint roller or the like.
  • an ink dispenser for example a paint spray gun, a paint roller or the like.
  • the pressure switch between the paint pump and the paint hose is arranged in the base station.
  • the placement of the pressure switch in the base station in front of the paint hose allows for improved and easy feedback to the paint pump, since the full, in color hose fitting color print for the pressure monitor is available.
  • the mounting in a compact assembly is possible.
  • the switch is adjusted via an appropriate bias so that the required hysteresis when switching on and off the paint pump is achieved.
  • a control loop ensures that the paint pump always provides a necessary minimum pressure in the paint hose, exceeds it, and shuts off at an upper limit of the pressure.
  • the hydraulic control line is designed as a flexible line, in particular as a rubber line to buffer over their own elastic extensibility additional hysteresis and / or slight pressure fluctuations in the system, such as pulsations of the paint pump.
  • the laying of the cable in the housing, especially at potential-free points, is thus simplified.
  • control fluid in the form of oil is arranged in the hydraulic control line.
  • control fluids offer particularly advantageous properties in the transmission of pressure to the switch, in particular via a pressure diaphragm.
  • the coupling agent between the Pressure monitor and the color line are designed as a pressure diaphragm, said coupling means are substantially edge and dead space integrated in a color channel on the pressure side of the paint pump. Congestion points or tapers in the area of the pressure switch in the paint channel are disadvantageous and should be avoided as they falsify the corresponding detected pressure. Therefore, the arrangement of the coupling means is to be designed as a pressure diaphragm, in particular in the region of a wall of the ink delivery to the paint pump.
  • the paint pump is expedient to design the paint pump as a peristaltic pump. Such pumps are established and can provide appropriate color pressure ranges.
  • the pressure reducer / pressure regulator functions as a measuring element via a hydraulic force transducer.
  • the operation of the pressure reducer / pressure regulator is described in the above parallel German patent application DE 10 2014 104 982.9 extensively set out. These are hereby incorporated by reference and their content to the disclosure and to the subject of this application, in particular the use of this pressure reducer / pressure regulator made in the second control loop.
  • FIG. 1 an inking system 1, which comprises a base station 2 and a paint spray gun 3 and a color supply in the form of a paint bucket 4.
  • the base station 2 is connected to the paint bucket 4 via a paint suction line 5, which is held in a hose guide 6.
  • a paint pressure line 10 leads to a connection 11 on the pressure reducer / pressure regulator 12 on the paint spray gun 3.
  • the pressure reducer / pressure regulator 12 is arranged below a spray head 13, at which the ink is misted in a known manner by a stream of air from a blower 14 and delivered.
  • a trigger 15 is provided in the region of a handle 16, which preferably operates a needle valve.
  • the trigger 15 is now released when the paint is provided in the paint-pressure line 10, then no ink is released from the spray head 13. It builds up a backwater of color in the pressure reducer / pressure regulator 12 via the terminal 11 and the paint pressure line 10 to the base station 2.
  • the ink pump is arranged, which is then deactivated via the pressure switch when reaching a predetermined maximum pressure.
  • FIG. 2 shows the open housing of the base station 2 and a color bucket 4 shown schematically, which is connected via a Farbansaug Ober 5 to the base station 2. Further shows FIG. 2 schematically the color printing line 10, which leads from the base station 2 to a front part of a paint spray gun 3, a so-called front end 17.
  • the inventive arrangement shows in the following embodiment, two control circuits, which are coupled via the color printing line 10.
  • a peristaltic pump 20 is arranged with a pump motor 21.
  • the Farbansaugtechnisch 5 is about led the pump inlet 22 to the peristaltic pump 20 and the peristaltic pump 20 provides at the pump outlet 23 a color print provided according to their pumping power.
  • a color pressure of 8 bar +/- 2 bar is advantageously regulated as a controlled variable.
  • Other, depending on the application appropriate color prints are also conceivable.
  • a component of the pressure switch 30, Connected to the pump outlet 23 is a component of the pressure switch 30, which receives the color pressure at the pump outlet as a measured variable via a membrane coupling 31 in a volume flowed through.
  • the color print at the pump outlet 23 is transmitted via the membrane coupling 31 to a hydraulic control line 32, which leads as a flexible cable which can be laid in the housing to a membrane switch 33.
  • An advantage of the flexible hydraulic control line 32 is that it can be performed in the housing in almost any but kink-free ways, and no potential guidance of an electrical switching operation in the region of the pump outlet 23 and the color printing area must be done.
  • the hydraulic control line 32 opens to the membrane switch 33, which has a membrane 34 on the upper side.
  • the diaphragm 34 is moved, preferably raised, by the color print transmitted by means of the hydraulic control line 32, thus lifting a spring lever 40 attached to a switch 41 as well.
  • the spring lever 40 may be preloaded with a spring tension to cover the necessary hysteresis of the controlled variable.
  • the spring lever 40 operated with sufficient increase a button 42 on the switch 41, which then performs a switching operation on the hose pump 20, in particular on the motor 21 or its control.
  • the setpoint adjustment of the control loop can take place via the spring lever 40, since this directly influences the controlled variable. If the pressure at the pump outlet 23 drops in color again, the pressure in the hydraulic control line 22 will also drop via the membrane coupling 31, and the membrane 34 at the membrane switch 33 will lower such that the spring lever 40 relieves the pushbutton 42 and the switch 41 accordingly served.
  • the paint pressure line 10 is arranged.
  • the pressure change ⁇ p1 propagates via the pressure line 10 to the color input line 141 on the pressure reducer / pressure regulator 12 at the front end 17.
  • the pressure fluctuation .DELTA.p.sub.2 will be applied to the color input line 141 as a disturbance variable, depending on the color printing provided by the ink pump of the base station 2 and how the pressure conditions in the paint tube have been adjusted. Both hydrostatic and hydrodynamic effects play a significant role here.
  • the pressure on the measuring element in the form of the hydraulic force transducer 160 propagates, which is presently designed as a diaphragm plate 151.
  • the diaphragm plate is understood as a measuring element, which is defined by the setpoint adjustment of a prestressed spring 154.
  • the controlled variable should be set in the form of 0.3 bar to 0.4 bar.
  • the hydraulic force transducer 160 or diaphragm plate 151 is moved in the direction of the spring 154 by the disturbance ⁇ p2 on the color input line 141, wherein a slider 144 coupled to the diaphragm plate 151 narrows or even closes the entrance of the color input line 141 to the diaphragm plate 151.
  • the thus provided control variable of 0.3 bar to 0.4 bar at the paint outlet line 156 is subject to the disturbance of the dispensed color volume and the concomitant pressure drop, which depends on whether the needle 110 pulled on the needle valve 105 of the spray head 13, so open or closed is.
  • the needle valve 105 When the needle valve 105 is closed, no ink leakage takes place, so that the pressure structure built up in the front end 17 between the color print in the color line 10 at the color input line 141 and the controlled variable in the color output line 156 is adjusted. As soon as a corresponding system pressure is reached, the pressure monitor 30 via the embodiment described above, the paint pump also stop and keep the system under static pressure. If then the needle 110 is withdrawn via the trigger 15 and thereby discharged color via the needle valve 105 on the spray head 13, a volume flow is created and the control on the second control circuit in the front end 17 of the paint spray gun 3 controls the desired color printing in the color output line.
  • paint roller or paint brush or the like which have a corresponding trigger or a paint dispensing valve and are supplied by a paint hose via a paint pump with paint.
