Definitions

  • the invention relates to a device for coating the lateral edge surfaces of elongated workpieces with a liquid coating medium, consisting of an adjustable coating head with a coating slot running in the direction of transport of the workpiece, into which an edge cross section of the workpiece is adapted and adapted to the edge end of the workpiece a line for the supply of the coating medium connectable, lateral slot nozzle opens.
  • Such a device is known for example from DE 42 07 090 C2.
  • This known device is able to provide continuously or discontinuously elongated workpieces with a liquid coating medium.
  • the workpieces can consist of wood, plastic, metal, stone or a composite material and can be designed as plates, strips or profile bars. The only requirement is that they have straight edges and thus straight edges so that they can be moved or transported in the coating slot of the coating head using a linear conveyor.
  • Pumpable and filterable, nozzle-compatible liquids such as pigment solutions, paints, varnishes, wood and corrosion protection agents can be used as coating media.
  • the workpieces are moved through the coating slot during the coating process.
  • the coating medium is sprayed onto the corresponding side edges.
  • the thickness of the finished, sprayed-on coating is approximately 0.008 to 0.2 mm. If greater coating thicknesses are to be achieved, it has hitherto been necessary to provide a second coating head. During the coating process, it can also occur that errors, for example interruptions, that is to say non-coated edge surfaces, occur which make a second coating process and thus a second coating head necessary.
  • more than two coating heads can be arranged one behind the other. When changing the workpieces to be coated, which have different lateral edge surfaces, it is always necessary to change the coating head and thus to set it up or align it exactly. If there is more than one coating head, the time required for this increases significantly. In addition, two or more coating heads inevitably require a larger space, each additional coating head also having to be connected to at least one line for supplying the coating medium and possibly also to a vacuum line.
  • the invention is therefore based on the object of providing a device for coating the lateral edge surfaces of elongate workpieces with a liquid coating medium, in which the time required for replacing and setting up the coating heads is reduced and the space requirement is reduced.
  • At a distance from the side slot nozzle at least one second side slot nozzle, which can also be connected to a line for supplying the coating medium, opens into the coating slot.
  • the coating head 1 is shown in perspective view, which consists of a metallic housing 2, which on its undetectable rear side in a known manner, not shown can be connected to a vacuum line.
  • the largely hollow housing 2 is provided on its front side 3 with a so-called coating slot 4, which can also be referred to as a passing slot.
  • the cross section of the coating slot 4 corresponds to the cross section of the lateral edge surfaces of the workpiece to be coated, the cross section of the coating slot 4 being slightly larger on all sides than the corresponding cross section of the edge region of the workpiece.
  • connection ports 5 On the housing 2 there are a number of connection ports 5, which are only indicated, and which can be connected to lines for supplying the coating medium via known or not shown connecting or coupling pieces.
  • a lateral slot nozzle 7 now opens into the same, which, except in the front area, extends completely over the circumferential surface of the coating slot 4.
  • the lateral edge surfaces of the workpiece can now be coated very precisely with the required coating medium via this slot nozzle 7.
  • the coating thickness is initially usually about 0.05 to 0.2 mm.
  • a vacuum applied to the housing 2 can, however, suck in air from the outside into the coating slot 4 from the front thereof be carried away by part of the coating medium.
  • the remaining coating then has a thickness of about 0.008 to 0.2 mm, but this is very much dependent on the viscosity of the coating medium and the surface structure of the side edge surfaces to be coated.
  • two further lateral slot nozzles 8, 9 are provided in the coating slot 4 in the exemplary embodiment shown, the lateral slot nozzle 9 at the end of the coating slot 4 and the slot nozzle 8 approximately is located in the middle of the coating slot 4.
  • These additional, lateral slot nozzles 8, 9 not only increase production reliability by leveling out possible defects; they also enable a thicker coating and a higher production speed, at the same time reducing the space required in relation to several coating heads and the time required for replacing the coating head 1 and adjusting or aligning it.
  • slot nozzles 10, 11 are provided in the coating slot 4 and extend longitudinally to the transport direction of the workpiece, which are then incorporated or come into effect when a particularly clean, lateral finish of the coating is to be achieved.
  • the lower slot nozzles 10, 11 running in the longitudinal direction of the coating slot 4 can also be arranged on the upper side of the coating slot 4.
