Definitions

  • the invention relates to a paint system for supplying paint to a coating device for the production line coating of workpieces, particularly vehicle bodies.
  • a known paint system such as disclosed in EP-PS 0 274 322, includes an enameling robot which carries the spraying device.
  • Interchangeable containers are filled at dispensing stations that are annexed to paint supply lines and are located in the spray booth in the movement range of the robot, from where they are picked up by the enameling robot itself as necessary.
  • the interchangeable containers can be coupled at different stations to any one of the numerous lines.
  • only two containers are provided, of which one container respectively is mounted to the robot while the other is being filled at a color changer annexed to connecting lines.
  • a system of this type avoids long tubes between the spraying arrangement and the supply lines and permits electrostatic coating with electrically conductive coating material without the problem of a conductive connection between the spraying arrangement and the supply lines.
  • the present invention provides a paint system for production line coating of workpieces, particularly vehicle bodies, having the greatest possible flexibility with respect to the paints, spraying arrangements and coating machines used.
  • the paint system includes a paint supply system which, when filling the interchangeable containers, limits the loss due to color change and provides a coating operation which is significantly free of delay.
  • the paint supply system also preferably manages to limit control effort for the control of required movements.
  • the paint system further includes a paint spray system including a coating machine whose exchangeable container can be coupled to the valve unit of the spraying device simply and with low control effort and which does not impair the dynamic motion behavior of the machine.
  • the containers can each be refilled with material of the same color.
  • the containers are rinsed only if a control and monitoring system establishes that the containers were not used for coating for a preset amount of time, or were not emptied completely during coating, or were not refilled after being emptied or in an exceptional case, if a container must be filled with a different color. Consequently, the loss of paint due to regular rinsing is avoided. Since color loss by means of rinsing only rarely occurs, the respective filling quantities also are not critical in this respect.
  • Loss of time can be limited to the time required to couple and decouple the containers to and from the paint spray system with an advantageous prior positioning of the containers of the transport assembly. For coating, this loss of time can also be avoided if at least two paint spray systems that alternate operation are provided.
  • the present paint system is suitable for supplying paint to any coating system, e.g. , to electrostatic systems for conventional enamel or electrically conductive water-based enamel, or to air atomizers; in fact, not only to robots such as the aforementioned known systems, but to any coating machines.
  • any coating system e.g. , to electrostatic systems for conventional enamel or electrically conductive water-based enamel, or to air atomizers; in fact, not only to robots such as the aforementioned known systems, but to any coating machines.
  • only simple movements must be controlled, which in turn can reduce the control effort considerably for robots and other multiaxis coating machines.
  • containers inserted in the transport assembly are removed at the discharge point by means of a linear movement assembly that moves the containers along a straight path between the coating assembly and the transport arrangement.
  • the arm that carries the spraying assembly can be pivoted, on the side of the machine facing the transport assembly, from or back to the transport assembly in order to take over the containers, said transport assembly likewise being simple to control.
  • the coating machine is conducted, parallel to the transport direction of the workpieces to the coated, to the discharge point, in order to take over and deliver the containers.
  • a container is preferably inserted through an opening of the arm into its interior space, where it can be coupled very easily, on one end, to control valves of the rinsing arrangement, and, on the other end, to an electromechanical drive for a metered emptying of the container.
  • the interchangeable containers can be filled relative slowly without causing delays for the coating operation due to their intermediate storage on the transport arrangement, there is no need for high pressure in the lines, which protects the coating material flowing in the lines, which as a rule is pressure-sensitive. For the same reason, pressure fluctuations in the lines are far less critical than for systems depending on the quickest possible filling.
  • the invention enables a trouble-free coating with practically any color shade, since not only are the colors delivered in previously conventional supply lines available, but furthermore, all possible mixtures of these and/or additional colors are available.
  • Mixing can be carried out in the container by filling it with different colors, or even prior to filling the container in question, and in fact, can be carried out automatically or manually by guiding together at least two different colors, e.g., from the annexed supply lines.
  • any optional preparation of colors, which can be selected with flexibility, is carried out fully automatically; it is executed by means of an electronic control system, according to the respective demands.
  • the transport assembly can also be equipped with containers filled externally, without being annexed to the supply lines of the filling station of the system described here.
  • a device At the filling station, a device shall be provided which automatically couples a container to a device fed by at least one supply line.
  • the arrangement of colors on the transport assembly can be carried out at any optional positions according to usefulness, since the automatic devices provided at the discharge point and at the filling station, in order to supply and remove or to fill the containers have free access to all positions on the transport assembly.
  • the filling station or at least the discharge point could be located within the spray booth in which coating conventionally is carried out.

  • the transport assembly in preferably located in the maintenance region of the system and is separated from the paint spray system by means of a wall, with containers being supplied to the paint spray system and returned to the transport assembly through an opening in the wall. Since the filling station is also located outside the booth, the closed circular supply lines, in which coating material circulates, do not need to be guided as far as into the booth. The lines can therefore be shorter and narrower.

  • the reserve magazine supply 212 can contain magazines 204 and/or single containers 28. They can be completely or partiaUy full, empty, used, or rinsed.
  • a reserve magazine supply with already filled containers could also be provided. Furthermore, it is possible to heat the reservoir so that the coating material is first brought to an optimum temperature.
  • the containers are preferably provided with thermal insulation during their transport to the coating device 200.
  • the containers 28 removed from the coating device at the transfer site 42 after use can be transported first into the reserve magazine supply 212, as illustrated, before they are reused at the filling site 32.
  • the magazine 204 used for transport into the reserve magazine supply 212 can be transported on similar conveyors 208, as on the path to the coating device 200.
  • the entire operating sequence is monitored and controlled, preferably by an aligning and control system 218.
  • This system ensures, in particular by using the mentioned characteristic data, that all existing coating devices are supplied as quickly as possible and with the smallest possible material losses, with the coating material needed in the particular case.
  • the containers used according to this invention have numerous, inherently advantageous properties. They are suitable for metering, airtight and designed as pressure vessels. They provide protection against aging of the coating material and act as transport containers, paint reservoirs and for decoupling of the coating devices from ring lines or other paint supply systems. They are portable, rinsable and reusable and they can be identified in a simple manner. Furthermore, they are easy to grasp and can be easily centered and locked into position.

Abstract

Ce système de peinture (20) comprend un système de réservoir de peinture (22) fournissant de la peinture à un système de vaporisation de peinture (24). On prévoit une unité de transport, telle qu'un magasin rotatif (26) pour une multitude de récipients interchangeables (28) destinés à une machine d'enduction. Ces récipients sont remplis en un endroit séparé de la machine d'enduction et ils sont retirés du magasin en un point de décharge et acheminés à la machine d'enduction, puis, après utilisation, ils sont ramenés au magasin. La machine d'enduction comprend un dispositif de vaporisation monté à une extrémité extérieure d'un bras de vaporisation mobile (58). Ce bras comporte un logement dans lequel sont indroduits les récipients remplis et une tige de piston qui vient coopérer avec un piston dans le récipient pour expulser la peinture hors du dispositif de vaporisation. Un appareil de mesure, mesurant la position relative de la tige de piston, détermine le débit du flux de peinture sur la base de la vitesse de changement de position de la tige de piston.
