Definitions

  • the invention relates to a coating agent changer, in particular a color changer for a paint shop, according to the preamble of claim 1.
  • the known color changer on several paint connections, which open via a respective controllable color valve in a common color line.
  • the desired paint is selected by controlling the associated paint valve while the other paint valves are closed.
  • the common color line In a color change, however, the common color line must first be cleaned of residues of the paint previously used to prevent deterioration of the Lackierieris after a color change.
  • the known color changer in addition to a detergent connection, a pulse air connection and a return port, which also open via controllable valves in the common color line.
  • all color valves are initially closed so that the paint supply is interrupted and the paint line can be cleaned.
  • the remaining paint still in the paint line is then pressed out with pulse air.
  • both the pulse air valve and the return valve is opened.
  • the common paint line is cleaned with a rinsing medium (eg thinner) and with pulse air.
  • the purge valve and the pulse air valve are opened alternately. After this cleaning of the common color line then the desired paint can be supplied by the associated color valve is opened.
  • a disadvantage of the known color changer is first the high detergent consumption, which is incurred in the cleaning of the common color line.
  • Another disadvantage of the known color changer is that the paint located in the common paint line can not be used in a color change and increases the paint consumption as a committee.
  • a color changer in which two paint connections open via a respective color valve in a common color line, wherein the desired color is selected by a corresponding control of the color valves.
  • the entire color line must also be rinsed here in order to free it from color residues of the previously applied ink, which is associated with the disadvantages described above.
  • double color changer are known in which two independently operable color changer are connected in parallel and the output side are combined via a separate control valve.
  • each of the two color changer has its own color line, so that when a color change, only one of the two color changer must be rinsed.
  • a disadvantage of such double color changers is the fact that the line volume to be flushed the color line between the respective color changer and the downstream control valve is relatively large due to the structural separation. In addition, the expenditure on equipment for such a double color changer is unsatisfactory.
  • the invention is therefore an object of the invention to provide a color changer, which has the lowest possible color and detergent consumption in a color change.
  • the invention comprises the general technical teaching of dividing the coating agent line in a coating agent changer into at least two line sections and thereby reducing the volume of the coating agent line to be cleaned.
  • the individual line sections of the coating agent line are in this case arranged within the coating medium changer.
  • the coating agent line is therefore preferably internal to the coating agent changer according to the invention, i. within the coating agent changer, divided into several line sections.
  • the coating agent changer according to the invention is preferably designed as an independent component, whereas the known double and multiple color change arrangements described above consist of an interconnection of several independent color changers.
  • the coating medium line consists of at least two line sections, into each of which a plurality of coating agent connections open for a supply of coating agent, wherein at least one of the individual line sections can be flushed independently of the other line section.
  • a color change it is then no longer necessary to rinse the entire coating agent line, whereby the consumption of detergent and paint is significantly reduced in a color change.
  • all line sections of the coating agent line can each be flushed independently of the other line sections. This can be achieved, for example, by connecting the individual line sections of the coating medium line in parallel and bringing them together at their downstream end via a changeover valve.
  • This variant of the invention is particularly well suited when the different paints used have similar frequencies of use.
  • only one of the line sections of the coating medium line can be flushed independently of the other line sections, wherein the independently flushable line section is arranged downstream of the other line section.
  • This variant of the invention is particularly well suited if the individual paints to be used have a very different frequency of use. In the painting of motor vehicle body parts, for example, so-called high-runner colors are used relatively frequently, whereas so-called low-runner colors are required relatively rarely.
  • the high-runner colors are preferably supplied in this variant of the invention, the line section of the coating medium line, which is irrigated independently of the other line section, whereas the less frequently used low-runner colors are supplied to the line section of the common coating agent line, which only together with the other line section of the coating medium line can be rinsed.
  • This variant of the invention with only one flushable line section can be realized for example by the fact that the individual line sections of the coating agent line are arranged one behind the other in the flow direction and merge into each other, which fluidly also can be referred to as a series connection of the individual line sections.
  • a shut-off valve is preferably arranged between the individual line sections in order to separate the individual line sections from one another and thereby permit separate flushing.
  • a rinsing agent connection preferably leads into the coating agent line between the individual line sections in order to be able to rinse the line sections independently of one another.
  • a further flushing agent connection which opens into the coating agent line, is preferably provided at the upstream end of the coating agent line.
  • the rinsing agent is then preferably supplied via the rinse agent connection, which is arranged at the upstream end of the coating agent line.
  • the flushing agent is preferably supplied via the flushing agent connection, which is arranged between the two line sections.
  • a return port is preferably provided to return coating agent residues from the coating agent line, wherein the return port preferably opens between the individual line sections in the coating agent line, to allow recycling of coating residues even if only one of the line sections of the coating agent line is rinsed.
  • a further return port is provided, which opens at the upstream end of the coating agent line in the coating agent line.
  • the individual line sections of the coating agent line are not connected in series, but run fluidically parallel and are merged downstream, the individual parallel line sections of the coating medium line preferably lead to a switching valve that selects one of the line sections.
  • the parallel guided line sections of the coating agent line are also brought together at their upstream end, for which purpose preferably a further changeover valve is used. This is useful in order to be able to select the desired line section in each bidirectional flushing of the individual line sections of the coating agent line.
  • the coating medium changer according to the invention preferably has a pulse air connection, which can be arranged downstream of the separately guided line sections and / or at the downstream end of the coating line and opens into the coating medium line.
  • At least one return connection is provided is provided upstream of the separately routed line sections and / or at the upstream end of the coating agent line into the coating agent line to return coating residues from the coating agent line.
  • the invention is not limited to a coating agent changer as an independent component, but also includes a coating system with such a coating agent changer.
  • the invention is not limited to those coating medium changers which have a coating medium line with only two separate line sections. Rather, it is also possible to divide the coating agent line into more than two line sections in order to further minimize paint and flushing agent losses during the color change.
  • coating system shown can be used, for example, for painting automotive body parts and has a rotary atomizer 1 as an application device.
  • the rotary atomizer 1 is connected on the input side via a metering pump 5 with a color changer 6, which selects one of a total of 20 possible colors F1-F20 and the rotary atomizer 1 feeds, the color changer 6 in FIG. 2 is shown and will be described in detail.
  • bypass valve 7 is further provided.
  • the color changer 6 is modular and expandable to adapt the number of selectable colors to the particular needs of the application can.
  • the color changer 6 a plurality of blocks 9, 10.1-10.7, 11, 12.1-12.3 and 13, wherein the individual blocks 9, 10.1-10.7, 11, 12.1-12.3 and 13 are connected to a common paint line 14 and control the inflow into the paint line 14 or the outflow from the paint line 14 via color control valves FV.
  • Blocks 10.1-10.7 serve to control so-called low-runner colors F1-F14, which are used relatively rarely, whereas blocks 12.1-12.3 serve to control so-called high-runner colors F15-F20, which are used relatively frequently.
  • Block 9 serves for supplying rinsing agent V1 via a rinsing agent valve SV1 and for returning color rests from ink duct 14 during a color change, wherein the return is controlled by a return valve RV1.
  • the block 13 arranged at the downstream end of the paint line 14 enables the supply of pulse air PL1 via a pulse air valve PV and a check valve 15.
  • the block 11 arranged between the blocks 10.1-10.7 of the low-runner colors F1-F14 and the blocks 12.1-12.3 of the high-runner colors F15-F20 has, on the one hand, the task of color line 14 into two line sections 14.1, 14.2 subdivide, wherein the downstream and used for the high-runner colors F15-F20 line section 14.1 of the color line 14 is irrigated independently of the upstream line section 14.2 of the color line 14.
  • the block 11 has a shut-off valve 16 which is arranged between the two line sections 14.1 and 14.2 of the color line 14.
