Definitions

  • the invention relates to a device according to the preamble of the claim 1.
  • Such a device is known from EP 0 293 065 A2.
  • This Document describes an apparatus for depositing viscous fluid on one surface.
  • the device includes an inner nozzle body through hole for the delivery of the viscous material and one funnel-shaped annulus that the conically tapered end of the Surrounds nozzle body and has an air outlet opening at the end.
  • This Air outlet opening is located in an adjustable lengthwise direction Use that allows the air outlet opening to be axially related to the inside the material opening located in the air outlet opening.
  • the task according to DE 41 20 881 Cl can be solved by surrounding the material nozzle Annulus is divided into individual axially parallel channels.
  • the object of the present invention is therefore the generic device form such that a uniform application of the viscous material can be achieved with relatively simple means.
  • the gas outlet opening is not surrounded by a razor-sharp edge, but through a cylindrical opening of limited length in the gas annulus final end wall can be formed. It is therefore sufficient if the material exit plane with the entry plane of this short cylindrical Opening section coincides, since here the gas flow is already full Has constricted.
  • the single figure shows a schematic longitudinal section through the Nozzle area of a device according to the invention.
  • the device also includes a material feed system, not shown for viscous material, a pressurized gas source and a controller for the Feeding the two media.
  • a cylindrical housing 10 is shown in the drawing, which together with a concentric tubular inside the housing 10 Inner part 12 defines an annular space 14 which is in the upper, upstream Area connected to gas connection openings 16, 18 of the housing 10 is.
  • the tubular inner part 12 has a channel 20 inside, through which the viscous material to be applied is passed.
  • the walls run of the tubular inner part with a blunt cone up to a nozzle opening 22 together.
  • the nozzle opening 22 formed as a short cylindrical portion that the wall of the penetrates tubular inner part 12 which is closed at the end.
  • the level at which this short cylindrical portion of the nozzle opening 22 ends in the flow direction and which is identified in the drawing by the reference number 24 be referred to as the plane of the nozzle opening of the material nozzle.
  • the housing 10 has a closure cap 26 lower, exit-side end, for example on the lower end of the cylindrical housing 10 with the aid of a not shown in detail Thread pair is unscrewed.
  • This cap 26 includes one End wall 28 which tapers the annular space 14 on the inside and transferred into a gas outlet opening 30, which is concentric with the nozzle opening 22 for the viscous material.
  • the gas outlet opening 30 penetrates the End wall 28 in the form of a short cylindrical section, which - related to the terminology introduced at the beginning - an entry level 32 of the Has gas outlet opening 30 and a corresponding outlet level 34. According to the drawing, the plane 24 of the nozzle opening 22 and the entry plane fall 32 of the gas outlet opening 30 essentially together.
  • the material flow of the viscous material does not therefore first enter the Funnel area at the end of the annulus, but directly into the initial part the gas outlet opening, in which the gas flow tapers sharply Has.
  • the plane 24 of the nozzle opening 22 can be in any position between the entry level 32 and the exit level 34 of the gas inlet opening 30, including, as shown, the entry level 32. It all that matters is that the flow of material tapered from the start and accelerated part of the gas flow is introduced.
