Definitions

  • the invention relates to a coating device, in particular for the painting of motor vehicle bodies according to the preamble of claim 1.
  • the painting is usually carried out by atomizers (for example high-rotation atomizers), which have only a single color input and are therefore connected on the input side with a separate color changer, so that a particular atomizer can apply varnishes of different colors.
  • atomizers for example high-rotation atomizers
  • the entire wiring harness between the color changer and the atomizer must be rinsed to clean the wiring harness of remaining paint residues.
  • this causes color change losses in the range of 25-70 ml (depending on the embodiment), which in exceptional cases can amount to more than 100 ml.
  • On the other hand disturbs the color change time required for a color change, which is in the range of 8-20 seconds, usually color change times of 13-15 seconds are achieved.
  • the required color change time depends on the rinsability of the colors used, the detergent used, the pressures of the media and the structure of the ink-carrying components and the position of the components on the application device.
  • EP 1 502 658 A1 Atomiser with an integrated color changer known also called ICC atomizer (ICC: I ntegrated C olour hanger C) denotes become.
  • ICC integrated color changer
  • An advantage of these known atomizers with an integrated color changer is the small volume of the wiring harness between the integrated color changer and the application element (eg a bell cup), which advantageously leads to significantly lower color change losses and a short color change time.
  • a disadvantage of the known atomizers with an integrated color changer is the fact that the possible number of colors is limited, since the available space is limited in the atomizer.
  • the external color changer has only a single color output and is not designed as an A / B color changer. With a supply of so-called low-runners on the external color changer, therefore, there is the problem that when changing from a low-runner to another low-runner a relatively large color change time is required.
  • the invention is therefore an object of the invention to provide a correspondingly improved coating device, which is particularly suitable for painting motor vehicle bodies and attachments.
  • a coating device according to the preamble of claim 1 is in DE 69722155 T2 disclosed.
  • the invention includes the general technical teaching to provide both in a coating device with a nebulizer both an internal, integrated in the nebulizer color change valve assembly and an external color change valve assembly, which is structurally separated from the nebulizer and preferably designed as A / B color changer.
  • the color change valve arrangement integrated into the atomizer is preferably used here for frequently used colors ("high runner”), since the color change time and the color change losses are extremely small with a color change of the integrated color change valve arrangement.
  • the separate external color change valve arrangement is preferably used for less frequently used colors ("low runner”) since a color change at the external color change valve arrangement is associated with greater color change losses due to the longer wiring harness between the external color change valve arrangement and the application element and a longer color change time takes.
  • the combination of high-runner and low-runner colors significantly reduces the system's average ink consumption / loss.
  • the atomizer in addition to the color inputs of the internal color change valve arrangement, has at least one further color input to which the external color change valve arrangement is connected.
  • the external color change valve arrangement feeds a paint input of the internal color change valve arrangement, so that the external color change valve arrangement and the inner color change valve arrangement are connected in series.
  • the external color change valve arrangement is designed as a so-called A / B color changer having two separately flushable color outputs. Accordingly, in addition to the color inputs of the internal color change valve arrangement, the atomizer has at least two corresponding further color inputs to which the two color outputs of the external color change valve arrangement are connected. Due to the two separate flushable color outputs of the external color change valve arrangement, the color change losses and the color change time are minimized even in the external color change valve arrangement and brought to the state of the aforementioned ICC.
  • At least one recirculation valve is provided, which permits a rinsing cycle (eg consisting of blanking, rinsing, filling or pressing with the next color material into the return line, ie dirt thinner recirculation) during the painting process of the other channel.
  • a rinsing cycle eg consisting of blanking, rinsing, filling or pressing with the next color material into the return line, ie dirt thinner recirculation
  • the external color change valve arrangement as A / B color changer preferably two return valves are provided, which allow for each color output of the external color change valve assembly a return and thus a rinse cycle.
  • the return valves may be arranged either in the atomizer or outside of the atomizer. An arrangement of the return valves in the atomizer in this case allows flushing into the atomizer, while the flushing in an arrangement the return valves outside the atomizer only up to the arranged there recirculation valve.
  • the external color change valve arrangement has only a single color output, which is associated with lower investment costs, a smaller space and a lower mass.
  • alternately high-runner and low-runner are preferably applied, so that during the application of a high-runner on the internal color change valve assembly enough time remains to flush the external color change valve assembly and press with the next low-runner.
  • the color change valve arrangement integrated in the atomizer is preferably fed by a first metering device with the differently colored coating compositions, wherein the first metering device is preferably structurally separated from the atomizer.
  • the first metering device for the integrated color change valve arrangement is preferably attached to the so-called "arm 1" of the painting robot, which is the proximal arm of the painting robot.
  • the first metering device for the color change valve arrangement integrated in the atomizer it is alternatively also possible for the first metering device for the color change valve arrangement integrated in the atomizer to be attached to the so-called "arm 2" of the painting robot, which is the distal robot arm of the painting robot.
  • the first metering device for the color change valve arrangement integrated in the atomizer is attached to a base body of the painting robot, wherein the base body can be moved along a rail (axis 7) and contains a rotation axis (axis 1) which rotates about the Z coordinate allows.
  • the first metering device for the integrated color change valve arrangement is arranged fixed inside or outside a paint booth, which is more difficult in most cases.
  • the external color change valve arrangement is usually fed by a second metering device, which may be of conventional design and therefore need not be described in detail.
  • the external color change valve arrangement and / or the second metering device associated therewith is attached to the so-called "arm 1" or to the so-called "arm 2" of the painting robot.
  • the aforementioned components are mounted in the immediate vicinity of the atomizer and therefore preferably mounted on the "arm 2".
  • the first metering device and / or the second metering device is designed as a gear pump, which is known per se from the prior art, such as from DE 600 09 577 T2 ,
  • the gear pump in this case preferably has a plurality of pump chambers, each with a rotatably arranged therein gear pair, wherein the individual pump chambers each supplies a paint input of the atomizer with the respective coating agent.
  • the gear pump in this case preferably has a common drive shaft for driving the individual gear pumps, which is not the case with the known gear pump mentioned above.
  • the gear pump according to the invention for driving the individual gear pairs in the individual pump chambers of the gear pump has a common drive shaft, which allows a drive by a single motor.
  • the gear pump has a plurality of couplings, which allows a selective coupling of the drive shaft with the individual gear pairs.
  • the individual clutches can thus selectively connect or disconnect the respective gear pair with the drive shaft.
  • the individual pump chambers are preferably arranged one behind the other in the longitudinal direction of the drive shaft, which allows a compact design of the gear pump.
  • the immediately adjacent pump chambers can in this case have a common chamber wall, whereby the required size of the gear pump can be further reduced.
  • the atomizer according to the invention comprises two modules which are separably connected to each other.
  • the first assembly of the atomizer preferably contains the internal color change valve arrangement, while the second assembly of the atomizer preferably contains the application element (eg a bell cup) and / or a main needle valve.
  • the application element eg a bell cup
  • the two modules of the atomizer are connected to each other by only a few lines, so that only slight contamination occur when a separation of the two modules.
  • the dividing line between the two assemblies of the atomizer were upstream of the internal color-change valve assembly, many color lines would run across the dividing line, which would result in significant contamination if the two assemblies of the atomizer were separated.
  • the internal color-change valve arrangement does not necessarily have to be arranged in that assembly of the atomizer which has the bell cup and the main needle valve. Rather, the internal color change valve arrangement can be arranged within the scope of the invention in another assembly of the atomizer, such as in a flange, a terminal block or an elbow.
  • atomizer used in the context of the invention is to be understood generally and includes, for example, rotary atomizers in the form of bell-type atomizers or disk atomizers and also ultrasonic atomizers, air atomizers, airless devices or airmix devices.
