Definitions

  • the invention relates to a changing system unit for different media, in particular a color changer for paint spraying systems, with separate feeds for each color and for cleaning fluid and / or for printing or.
  • Purge air which have feeds, blocking elements and can be connected to a common outlet.
  • paint changers are used, which are arranged between the individual paint reservoirs and the paint spraying device.
  • the known color changers usually have cuboid or circular cylindrical housings which are arranged vertically with their longitudinal axis and have a central interior space which extends practically over the entire length.
  • the feeds for the individual colors as well as for the cleaning fluid and / or the pressurized or flushing air are arranged vertically one above the other, depending on the size and number, one-sided or also opposite or evenly distributed radially around the circumference lead into the interior, whereby access can be blocked off by means of blocking elements assigned to each infeed.
  • the feeds are designed as modules which are arranged in a cascade. It is provided that at least two infeeds each form a cascade module which has its own output which serves as an infeed for a further cascade module or is provided as a common output for the upstream cascade modules.
  • a first design relates to a design in a flat design, in which the connections for the different colors and for the cleaning fluid and / or the compressed or purging air are arranged horizontally next to one another along a straight line, with two such feeds each forming a cascade module which is connected to the neighboring cascade module is combined to form a further cascade module until finally a module remains as the last stage, the output of which forms the common output for all infeeds.
  • the other design relates to a concentric arrangement of the feeds on a circle, with two feeds forming a cascade module and the outputs of two modules being combined in a further cascade module, which is arranged on a pitch circle with a smaller radius, until finally the output the last cascade module formed in accordance with this systematics, d. H. coaxial with the longitudinal axis of the stepped cylinder thus formed, exits.
  • each cascade stage can also be configured modularly as a uniform, compact component with the respective number of feeds and outputs.
  • the locking parts of the slide of each cascade level are connected to each other, for. B. in one piece, which ensures that only the specified fluid path is unlocked.
  • each feed of a cascade module be it the first feed or the follow-on feed from the Output of an upstream cascade module, lockable with a slide.
  • the slides in question are designed as round or flat slides.
  • a common rotary slide is provided for each cascade step, in which by rotating its locking part, for. B. a special perforated disc, the desired one Fluid path unlocked, whereas the other fluid paths are blocked.
  • a further improvement of the invention provides that the actuating members and locking parts of the locking members designed as sliders of each feed are controlled by a central control which ensures that the specified fluid path is exactly maintained.
  • the configurations provided according to the invention are distinguished by comparatively small structural dimensions, which is based on the modular construction provided according to the invention.
  • This color changer arrangement consisting of a few parts, can therefore be easily disassembled in a few minutes if an unexpected malfunction should occur. They can be assembled just as quickly, and assembly can be facilitated by appropriate centering aids and the like.
  • Another advantage of the color changer according to the invention which results from the modular structure, allows the connection options for the fluids in question to be varied in a very variable manner in accordance with the desired variety of fluids. By adding or leaving out a cascade level, the number of available feeds can be doubled or halved.
  • Another advantage associated with the simple structural design is that only a few mechanically moving parts are provided, namely only the locking parts of the locking members, which has a favorable effect on a very low susceptibility to failure. Also, with the color changer according to the invention, only fewer control lines are required to control the blocking elements, since these correspond accordingly an advantageous embodiment of the invention are mechanically coupled.
  • connections for the fluid supply to the first feeds have a known quick-change system which allows the respective supply line to be connected to the color changer simply, quickly and safely.
  • the locking parts of the slide are solvent-borne, which has a favorable effect on the wear behavior of the locking parts and on their closing behavior.
  • shutoffs of the individual fluid paths provided according to the invention proves through the use of slides, which are each arranged transversely to the flow direction, so that no "dead corners" in the form of blind holes and the like can form, in which paint residues get stuck and when Rinsing process can not be removed.
  • the feeds 12, 13, 14, 15 are provided with locking members 20 designed as sliders, the associated locking elements being coupled to one another in each cascade stage and being acted upon by a schematically illustrated control 22 via corresponding connecting lines 24, so that only one at a time The fluid path is activated from its feed 12, 14, 15 to the common outlet 19.
  • FIG. 2 shows a further embodiment of a color changer 30 according to the invention which, as can be seen from FIG. 3, is designed as a stepped circular cylinder.
  • the feeds 32, 34, 35 provided for the supply of paints or cleaning fluid and compressed air are arranged on the upper end face of a circular cylindrical housing 31 at a uniform distance from the edge on a circle.
  • connection of the individual fluid feeds 32, 34, 35 to the outlet 39 located on the opposite side is cascaded in three stages I, II, III.
  • the feeds 33 for the downstream cascade stages II and III are shown in broken lines in FIG. 2, as is the common output 39.
  • a blocking member 36 which is designed as a rotary slide valve, is arranged, which can be rotated about the common central axis and via control lines 37 can be actuated by a schematically illustrated control 38.
  • the very compact design combines the advantage of a very simplified control for the activation of the respective fluid path, since only for each cascade level a control line is required, which is advantageous in view of the smaller number of required fluid connections. For this reason too, the size of the color changer 10, 30 according to the invention can be kept small (theoretically a few mm high).
