Definitions

  • the present invention relates to an application device with a carrier unit and an application unit that can be pivoted between a minimum and maximum inclination.
  • Such application devices are used, for example, in production facilities for the production of at least partially coated and/or impregnated floor elements in order to coat sections of the floor elements, such as joining surfaces or bevels, or to provide them with a non-layer-forming impregnation agent.
  • the coating or impregnation agent is usually picked up from a container by a rotating transfer wheel.
  • the floor element to which the application takes place is typically moved by a transport device relative to the transfer wheel.
  • the transfer wheel transfers the coating or impregnation agent to the respective section of the moving floor element.
  • the application is usually carried out contactlessly using adhesion forces alone.
  • the transfer wheel In order to transfer a sufficient amount of coating or impregnation agent to the transfer wheel, the transfer wheel is at least partially immersed in a stationary container with the coating or impregnation agent using a device.
  • the transfer wheel is arranged pivotably against the container, so that the transfer wheel can be tilted into the coating or impregnation agent at different angles of inclination.
  • the annular end face and, in the case of larger diameters, sections of the two side surfaces of the disc-shaped and rotating transfer wheel are wetted by the coating or impregnation agent.
  • the level of the coating or impregnation agent in the container is always kept constant by means of an overflow pipe.
  • the transfer wheel Due to the varying inclination and tilting of the transfer wheel, it dips variably deep into the coating or impregnation agent relative to the constant filling level of the coating or impregnation agent and therefore at times unnecessarily too deep into the coating or impregnation agent.
  • the deeper the transfer wheel is immersed the more of the outer surface of the rotating transfer wheel is in contact with the coating or impregnation agent. Excess coating or impregnation agent is scraped off the transfer wheel using a scraper and forms undesirable deposits on the scraper, which can negatively influence the application result.
  • Fluid technology e.g. a pump or a filter
  • the task is to provide an optimized setting of the immersion depth of the transfer wheel in the coating or impregnation agent.
  • the application device has an application unit which is arranged with an inclination relative to a carrier unit which can be arranged on a base.
  • the application unit comprises a container with a coating or impregnation agent to be applied in particular to floor elements.
  • the application unit has a transfer wheel, which can be at least partially immersed in the coating or impregnation agent and partially protrude from a container opening.
  • the application unit i.e. the transfer wheel together with the container, can be between one Minimum inclination and a maximum inclination can be arranged tilted.
  • the immersion depth of the transfer wheel can change, at least in places, and be undesirable.
  • the overflow designed according to the invention enables a variable volume flow of the coating or impregnation agent to adjust its fill level as a result of the pivoting of the application unit, so that the immersion depth of the transfer wheel in the coating or impregnation agent can be kept as constant as possible.
  • the overflow has a contour with a first overflow edge and a second overflow edge. The coating or impregnation agent can flow over the first overflow edge at the maximum inclination and over the second overflow edge at the minimum inclination.
  • the application unit is arranged pivotably between the minimum inclination and the maximum inclination. This allows the inclination of the application unit to be adapted to differently inclined sections to be coated or impregnated.
  • the application unit can be pivoted manually or via a drive.
  • the contour is designed as a closed line, with the first overflow edge and the second overflow edge being straight and intersecting at an intersection.
  • the two overflow edges are arranged closer to the ground relative to the rest of the contour, ie lower with respect to a vertical direction of the application device.
  • the two overflow edges can in particular be designed in such a way that they resemble a heavily compressed V-shape, in which the two legs of the V-shape are wide apart. By approximating a V-shape, a drainage channel with a geometrically unhindered flow can be provided.
  • the rest of the contour which is designed as a closed line, is preferably curved or curved.
  • first and second overflow edges can be arranged horizontally at the minimum and/or maximum inclination.
  • the overflow can be configured such that the intersection of the two overflow edges forms the lowest point of the contour for all orientations of the overflow located between the minimum and maximum inclination.

  • a flat side surface of the transfer wheel or its imaginary extension can function as a reference surface corresponding to the intersection point. Reference point and reference surface can serve together to set a desired, in particular as constant as possible, immersion depth.
  • the application unit is preferably always filled up to the height of the intersection.
  • an obtuse angle is formed between the first overflow edge and the second overflow edge, the angle being greater than 110°, preferably greater than 140° and particularly preferably greater than 155°, in particular 160°.
  • a flow cross section of the overflow formed between the overflow edges can be expanded by an obtuse angle - i.e. 90° to 180°. Drainage through the overflow can therefore be facilitated by means of an obtuse angle.
  • friction losses when conveying the coating or impregnation agent can be reduced, since the conveying speed can be reduced with a larger flow cross section to achieve a desired volume flow. Consequently, an obtuse angle can increase efficiency.
  • a preferred embodiment of the invention provides that a pivot angle between the minimum inclination and the maximum inclination is greater than 0° and less than or equal to 70°, preferably greater than 0° and less than or equal to 40°, particularly preferably greater than 0 ° and is less than or equal to 25°, in particular 20°.

  • the first overflow edge can dip below the surface of the coating or impregnation agent.
  • the further the angular deflection is in the first direction of rotation the deeper it can be The first overflow edge moves below the surface of the coating or impregnation agent and, as a result, the larger the flow or outflow cross section of the coating or impregnation agent can be made below the surface.
  • the first overflow edge can penetrate the surface, can be arranged above the surface as the deflection in the second direction of rotation progresses, and the second overflow edge can be below the surface of the Immerse in the coating or impregnation agent.
  • a further flow or outflow cross section of the coating or impregnation agent can be opened, which can be increased with increasing deflection in the direction of the minimum inclination.
  • the overflow is arranged on an inner surface of the container which is curved.

  • the overflow can be arranged on an inner surface of the container, analogous to a bathtub or a sink.
  • the overflow or its contour preferably has an extension both in a direction perpendicular to and parallel to the ground. This means that the coating or impregnation agent cannot flow into the overflow unidirectionally, but rather from several directions.
  • a curved inner surface also offers the advantage that the coating or impregnation agent can flow off advantageously without sticking to sharp contours or grooves and/or drying out. The cleaning effort and cleaning intervals of the application unit or container can therefore be reduced.
