Definitions

  • the invention relates to a nozzle arrangement for application of coating material into cavities of objects, in particular vehicle bodies, according to the preamble of claim 1.

  • the nozzle element is generally designed as an elongate nozzle lance, whose free end has a plurality of discharge openings.
  • the nozzle lance is guided by means of an arm of a multi-axis application robot and pushed for application in a cavity of the vehicle body to be treated, so that the area of the nozzle lance with the discharge openings is located in the interior of the cavity. If necessary, the application can also be done by hand.
  • a nozzle assembly having the features set out in the preamble of claim 1 is known from FR 1 280 937 A known.
  • a vehicle body has up to 120 cavities, which can differ greatly in their geometry. However, it must be ensured that all different cavities are fully and reliably lined with wax to provide satisfactory corrosion protection.

These are adapted in shape, number and arrangement of the respectively associated discharge openings to a particular type of cavity of a particular vehicle body, so that wax can be injected into the cavities in matching dispensing angles and points. It could be assigned to a cavity types in their geometry different cavities. Depending on the vehicle body to be treated up to 80 different nozzle elements may be necessary for the cavity preservation.
  • the nozzle arrangement is the US Pat. No. 6,554,212 B2
  • the nozzle arrangement is the US Pat. No. 6,554,212 B2
  • a flowable compressed air / wax mixture is generated in a known manner, which is conveyed to the discharge openings of the active nozzle lance and there applied simultaneously via all discharge openings in the cavity.
  • the space required for the folding mechanism is very large compared to the dimensions of the nozzle elements. This restricts the accessibility of cavities, in particular in the interior of the vehicle body.
  • the nozzle elements are contaminated by externally adhering wax and must be cleaned after a certain period of operation.
  • the replaceable head must usually be removed from the robot arm and cleaned separately at another location.
  • an identical replaceable head In order to maintain continuous operation during cleaning of the replaceable head, an identical replaceable head must be present, which is used in exchange for the replaceable head to be cleaned. This in turn is reflected in the total cost of ownership.
  • the coating material can optionally and in contrast to known nozzle arrangements so that they are selectively applied via one or more specific discharge openings in the nozzle element.
  • One and the same nozzle element can thus have a plurality of dispensing openings, of which only one part is used for a first type of cavity and another part for a second type of cavity, etc.
  • One and the same discharge opening can be for several different Voids are used, optionally in combination with each other other discharge openings and discharge pressures.
  • Coating material may be dispensed via the first dispensing opening into a cavity of a first type by the guide directing the coating material corresponding to the first dispensing opening. If a cavity of a second type is to be provided with coating material, the coating material is then passed via the guide to the second discharge opening. Depending on the type of cavity, the application must be made at different locations of the cavity.
  • one and the same nozzle element can be used for different types of cavities, without requiring replacement of the nozzle element.
  • the cycle times are thereby increased, which is reflected in a greater efficiency of the coating process and thus in lower operating costs.
  • the guide device is a guide body, which is arranged in the interior of the nozzle element and defines at least one flow channel and defines different flow paths for the coating material depending on its position or position.
  • a guide body is mechanically less susceptible as a one-piece compact component.
