Definitions

  • the invention relates to a device for applying a strip-like lacquer layer to the connecting seam on the inside of a can body that is open at both ends, with an application roller located in a lacquer bath with grooves on the circumference.
  • the rectangular blank provided for the production of a can body is generally bent cylindrically and its longitudinal edges are connected in metallic fashion by roller seam resistance welding. With regard to the metallic connection, the edge zones of such a blank are not pre-painted.
  • the connecting seam on the inside of the can body is provided with a lacquer strip, the lacquer strip being so wide that it covers the base lacquer printed outside the edge strips.
  • the grooves machined into the originally cylindrical peripheral surface of the applicator roll are transverse, i. H. arranged parallel to the axial direction of the application roll.
  • the aim is to ensure that the paint is taken safely from the paint bath.
  • the transverse grooves press air that has accumulated on the liquid lacquer into the lacquer coating applied to the connecting seam. After drying, such a coating has bubbles which adversely affect the corrosion protection of the coating.
  • the invention has for its object to provide a device of the type mentioned, with which the application of a bubble-free stripe-shaped lacquer coating on the inside of a can body is possible.
  • the can body is generally designated 1 and its connecting seam 2.
  • the connecting seam 2 of the can body 1 is produced on a resistance roller seam welding machine 10 with two roller electrodes 11, 12, of which the lower electrode roller 12 is mounted in a cantilever arm 13 fastened to the machine frame of the welding machine.
  • the can bodies 1 are transported by a chain drive 16 provided with drivers 15.
  • a magnetic tape 17 is provided, which consists of two magnetizable, endless individual tapes 17 ', 17 "which are guided around two deflection wheels 18 and 19 rotatable about vertical axes.
  • the device for applying the lacquer layer to the connecting seam has an arm 20 which is articulated at 21 on the cantilever arm 13.
  • a small roller 22 is supported on the underside of the free end of the arm 20 and is supported on a roller 23 mounted on the machine side.
  • the arm 20 is provided with a tank 24 which is expediently designed as an exchangeable container 25 and which can be inserted into a recess 26 in the arm 20.
  • the arm 20 is also provided with a paint or application roller 27, which is located essentially within the tank 24 and only protrudes from the tank 24 with its section located at the top.
  • a motor 28 arranged on the arm 20 with a gear 29 is provided for driving the application roller 27.
  • the application roller has a sprocket 31 at one end of its axis 30 and is driven from the transmission 29 via a chain drive 32.
  • the originally cylindrical peripheral surface 33 of the application roller 27 is provided with grooves 34 which run perpendicular to the axis of rotation 30 'of the application roller 27 and which are distributed uniformly over the entire width of the original peripheral surface 33 of the application roller 27.
  • the grooves 34 preferably have a depth f of 0.2 to 0.8 mm and a distance t from one another of 0.15 to 0.7 mm (cf. also Fig. 4).
  • the application roller 27 of the device is provided with grooves 34 which, like in the case of a thread, are helically worked into the originally cylindrical peripheral surface 33 of the application roller 27.
  • the grooves have an axial distance t from one another, the slope s of the grooves 34 corresponding to the distance t or a multiple thereof.
  • the angle 6 formed by the grooves 34 and the axis of rotation 30 ' is in the range between 85 ° and 90 °.
  • the can body can be guided precisely aligned when painting.
