Definitions

  • the present invention relates to a method for workpieces which are to be spray-coated in continuous operation, for preventing coating medium from depositing on parts of the workpieces which are not to be coated, wherein parts which are not to be coated and parts to be coated are separated by means of a cover during the coating process.
  • a template-like masking of coating medium without actually covering the workpieces is known from DE-OS 25 58 846.
  • the aim of the present invention is, on the basis of a method of the type mentioned, to remedy the disadvantages mentioned which arise with a cover which can be described as dynamic.
  • the outer surface is not contaminated by the medium, be it that the outer surface is already printed or that this outer surface is still to be printed, with the coating medium adhering there affecting the print quality impaired.
  • Continuous coating processes are now known, in which the workpieces are moved during the coating, such as in the case of the weld seam coating of can bodies.
  • coating methods are also known in which the continuous operation takes place in a clocked manner and the coating is carried out in standstill cycles, for example by spraying out the interior of hollow bodies in stop cycles.
  • the workpieces are positioned and fed to a coating station.
  • a system for preventing parts of the workpiece which are not to be coated from being contaminated with coating medium comprises covering elements which include separates parts of the workpieces to be coated from those not to be coated during the coating process.
  • the covering members are motion-coupled to the conveyor device according to the wording of claim 7. This ensures that, at least during the coating process in the spraying station, there is no relative movement between workpieces and covering elements; the covering mentioned thus takes place in the sense of a static seal.
  • the movement coupling mentioned is realized in a very simple manner, preferably according to the wording of claim 8, according to which at least some of the covering members are attached to the conveyor.
  • covering shoes are fed, for example, from above to the holding shoes loaded with the workpieces, so that finally the holding and covering shoes jointly cover the outer surface of the workpieces and thus feed them to the inner coating station.
  • the cover shoes are preferably supplied according to the wording of claim 10.
  • the holding and covering shoes are designed with receiving trays oriented in the direction of movement of the conveyor. If, at the coating station, such as by lance coating, the interior of the hollow workpieces is coated and the continuous operation is controlled clocked for this purpose, for example always a number of workpieces are coated on the inside at the same time by coating lances, the holding and covering shoes are transversely to the direction of movement of the Provide conveyor-aligned receiving trays.
  • this problem can be remedied by repeatedly covering the covering elements, ie the holding and receiving shoes mentioned, with the circulating operation of the conveyor device as a belt conveyor, at which they are cleaned of the contamination mentioned.
  • the coating is to be homogenized along the entire inner surface in that the hollow body is rotated about its longitudinal axis during the coating, it is proposed according to the wording of claim 14 to provide drive means on the holding and / or covering shoes and they preferably come into frictional contact with the workpieces to leave to drive the latter.
  • the expandable holding mandrels provided to cover the inner wall are preferably designed in a simple manner as inflatable stockings according to the wording of claim 16.
  • the covering elements can also split the workpiece release, and it can be forcibly generated air circulation through these gaps, whereby a covering effect on the workpiece is also achieved.
  • FIG. 1 shows a side view of a first embodiment variant of the method according to the invention or of a device designed for this.
  • this exemplary embodiment it is a question of coating, as a workpiece, tubular components which are open on both sides, for example and in particular can bodies, on their inner walls in a known manner, be this in whole or, on this wall, only preferred parts, in particular the batch of the can body weld.
  • a work arm 3 is provided for the inner coating of the can frames 1, which projects further from a welding arm to close the frames which were previously still open.
  • At least one feed line 5 for coating medium is provided in arm 3, possibly also a return suction line 6 for medium not applied and, in the case of electrostatically assisted coating, the electrical supply (not shown) for a high-voltage electrode arrangement.
  • a nozzle arrangement 5 is provided on the arm 3, a nozzle arrangement 5a for coating a longitudinally extended inner wall area, such as the weld seam area, or a nozzle arrangement 5b for spraying out the entire inner wall of the can body.
  • the can bodies 1 are driven in rapid succession along the working arm 3 by means of a conveyor device with an endless belt 7, be it a plastic, a metal or a chain belt.
  • a conveyor device with an endless belt 7, be it a plastic, a metal or a chain belt.
  • holding members 9a according to the invention are now attached to the belt 7 at regular intervals, which initially serve to advance the can bodies 1 in a defined position along the working arm 3.
  • the conveyor belt 7 is driven in a conventional manner and depending on its design by drive rollers and guided by guide rollers, one of which, 11, is shown in FIG. 2.
  • the holding members 9a are trough-shaped, with a trough 13 which extends parallel to the longitudinal extension of the band 7. Lying in this tub 13, the respective can body 1, as again clearly shown in FIG. 2, is advanced.
  • the tub 13 is dimensioned such that it essentially directly covers and covers half the circumferential surface of the outer frame wall in a form-fitting manner.
  • a second conveyor belt 15 is provided, which runs in front of the area on the working arm 3 with the spray nozzle arrangement 5a or 5b against the conveyor belt 7, in a first area 17, thereafter at least substantially parallel to the conveyor belt 7 runs, in an area 19 and after the spray nozzle arrangement 5a or 5b again pivots away from the conveyor belt 7 into an area 21.
  • the holding members 9a are fastened to the band 7 in such a way that their deflections can easily follow, as shown at 29, for example, so that they are pivotally connected within limits.
  • the cover jaws 9b are constructed at least substantially the same as the holding jaws 9a, ie they also have a trough-shaped indentation 31 , which in turn corresponds at least essentially to half the outer surface of the can body.
  • the covering jaws 9b in front of the nozzle arrangements 5a and 5b, are moved against the frames 1 inserted in the troughs 13 of the holding jaws 9a, and then, in the web area 19 of the conveyor belt 15, they fit snugly the outer wall of the can body 1 in such a way that the latter are now covered essentially in a form-fitting manner on their entire outer surface by the holding jaws 9a and the covering jaws 9b, which now also act as covering jaws.

  • the second band 15, as shown in FIG. 1 in the region 21 bends away from the band 7 again, and the cover jaws 9b are lifted off the can bodies 1 again.
  • the conveyor belts 7 and 15 preferably move the latter with the jaws 9a and 9b through cleaning stations 33a and 33b, as shown schematically in FIG. 1. In it, the jaws 9a and 9b are cleaned of the coating medium to which they were exposed due to their covering effect during the coating process.
  • this procedure has the advantage that, for the temperature reasons mentioned, relatively expensive insert material for the inserts 35, such as Teflon, has to be used, that the contaminated insert 35 can be removed, new inserts can be introduced and the contaminated inserts can be cleaned centrally , while the coating system continues to work practically without interruption.
  • the insert cleaning then does not have to be carried out in a continuous cleaning process, but can be carried out anywhere.
  • the diameter D of the covering troughs on the jaws 9a and 9b can be changed by thicker or thinner inserts 35, which means that the device can be quickly converted for processing different sizes of can bodies 1.
  • the trough parts 37 of the inserts 35 can be designed to be elastic, so that the covering form fit of the interacting jaws 9a and 9b is increased.
  • FIG. 4 A further embodiment variant of the one already illustrated with reference to FIG. 1 is now shown schematically in FIG. 4.

Both end portions of the cover jaws 9b are formed with protruding collars 103, which protrude in such a way that the rollers 101 protrude only minimally above the collars 103. With an inserted (not shown here ) can bodies lie primarily on the rollers 101, and a thin air gap remains between their outer wall and the collar 103. A can body inserted into the cover jaw 9b in this way is also covered by this jaw 9b to prevent contamination by the coating medium.
  • the holding jaws 9a in turn have freely running, axially aligned rollers 105 along their troughs 13 and, also at the end, as described with respect to the jaws 9b, have a collar 107.
  • balls can also be provided instead of the free-running rollers described so far.
  • the stacked jaws 9a and 9b result in either a ball bushing or a roller bushing.
  • a can body 1 inserted between these jaws can be rotated about its axis A with little resistance.

  • the roller 109 is preferably resiliently mounted in the direction of the plane E and can, to a limited extent, and as shown in broken lines at 111, be lifted into the tub 13 against the force of a spring element, for example on its bearings.
  • the transfer roller 111 is preferably not only rotatable on the jaw 9a, but, as with the spring bearing 113 and the arrow P Darge provides resiliently movable in the direction of the plane E.
  • the jaws 109 are mounted on hinges 7a, 7b, which are preferably arranged on both sides in this embodiment, in an articulated manner, as shown at 29, in order to follow the path of the strap 7 according to FIG. 1.
