Definitions

  • the present invention relates to a fluid supply device for a spray system, in particular for a paint or paint spray system, and a method for their use.
  • the system For a color change in a spray booth, the system must be cleaned of the color used and then replaced with the new color.
  • the supply lines to the atomizer and all parts therein, such as color changes, pressure regulators or dosing units, are cleaned with a cleaning fluid. In such processes, the paint in the line is discarded, which involves a high consumption of paint and cleaning fluid and a long flushing time.
  • Another method of cleaning feed lines is to piggy back the paint into a loop and then clean the feed lines with cleaning fluid.
  • the loss of color in a color change can be kept relatively low, but the technical complexity of the control is very large, making such systems are very prone to failure and expensive.
  • German patent application DE 3534269 A1 discloses a color change valve with at least two provided on a housing inlet channels. Furthermore, the document describes a channel leading to the spray gun and this upstream shut-off valves, which control units are assigned.
  • the publication proposes waiving a separate housing for use as an add-on single module of a color changing and dosing, that the rod-shaped housing a Mitteilteil has, which has the inlet channels and laterally offset to the channel output.
  • document DE 3 534 269 A1 discloses a fluid supply device for a spray system according to the preamble of claim 1.
  • a paint spraying system with color change system is known, wherein the color change system of a spraying or discharging device allows at least one of a plurality of ready held ink, lacquer and / or hardening fluids arbitrarily selectable fluid supply. It is envisaged that virtually all lines that lead to sedimentation-prone flies are constantly flowed through by the respective fluid.
  • US 2003157262 A1 describes a method for producing and spraying a multi-component paint in an installation comprising a main pipe, wherein on one side of the main pipe is a line for supplying a primary color and on the other side of the main line a spray system is provided.
  • the main line includes a control device which controls the flow rate of the product.
  • US 3857513 is a semi-automatic color change system for a paint spraying installation known.
  • the system includes several fluid supply lines, including at least two color lines and a solvent line.
  • the system includes a valve-controlled paint spray nozzle, a liquid flow line, a pressure regulator, a fluid pressure control means, and a selective fluid supply control means.
  • the problem to be solved was thus to provide a fluid supply device for a spray system, which allows a fast and efficient color change and in particular in the necessary cleaning to a pigging system waived. Farther should such a fluid supply device characterized by a low installation and cost.
  • a fluid supply device is constructed for a spray system of two modules.
  • the second module comprises at least two independent lines for supplying the paints or varnishes from a second color changer to a third color changer and / or a two-component mixer, wherein the third color changer and / or the two-component mixer release valves and / or return lines for colors or Paints and preferably disposed in the immediate vicinity of the spray device.
  • valve assembly according to the invention allows a low installation and cost of operation and in particular the necessary cleaning. Furthermore, no elaborate pigging systems are used.
  • the fluid supply device according to the invention can be used in the second module optionally with any number of color changers and / or two-component mixers be equipped.
  • Fluids in the context of the present invention are all fluids that can be used for a surface treatment, in particular paints or varnishes.
  • the device according to the invention thus makes it possible to transport a plurality of paints or lacquers, for example 20 or 30 paints or lacquers, separately to one another in the fluid supply device.
  • cleaning fluid means suitable solvents which can completely remove the respective paints and varnishes.
  • a two-component mixer is provided in the second module to provide this module with a supply line for a curing agent, wherein the dosage of the curing agent by a valve, hereinafter referred to as a hardener valve occurs.
  • a hardener valve occurs.
  • the color changer has circulation valves. Needle valves are advantageously used for the circulation valves, paint valves and hardener valves, these being pneumatically on and / or abêtbar via control lines.
  • the control is advantageously computer-based, for example via a PLC system.
  • the metering pump is connected in the first module via a separate flush valve with a detergent line;
  • this metering pump can be flushed with a detergent regardless of the rest of the system, with particular advantage, the metering pump is a flushable gear metering pump.
  • the first module is mounted outside a cabin or on a cabin wall and the second module is mounted on a robot or painting machine.
  • paints or lacquers are introduced into the first color changer with arranged therein color valves and circulation valves. At least two independent lines for the circulation of the paints or varnishes, these from the first color changer to a second Color changer are guided with release valves arranged therein. Furthermore, the paints or varnishes are fed via at least two independent lines from the second color changer to a third color changer arranged in a second module and / or a two-component mixer. If it is expedient, two or more color changers and / or two-component mixers and any desired combinations of these can in principle also be arranged in the second module.
  • the colors can thus circulate continuously through the system in separate circuits or, with appropriate valve switching, optionally be supplied by the third color changer and / or the two-component mixer to a spraying device.
  • air and / or a liquid cleaning agent is passed through the first color changer, through a common line with a pressure regulator disposed therein and a metering pump via the second color changer through a drain valve in a drain line.
  • air and / or a liquid cleaning agent is simultaneously passed through the third color changer and / or the two-component mixer and the spray device.
  • the fluid supply device also has the advantages that, despite an external metering pump, the colors can circulate through the complete device and the circulation can be switched on or off. Furthermore, it is advantageous that there is a very small loss of color and cleaning agent, a quick color change despite external pumps, easy and fast accessibility to all components is given and the cost of the technology and the control structure compared to a pig system very is low.
