Definitions

  • the invention relates to a device for applying glue to wooden parts to be glued, with a feed device for the wooden parts, a hollow body arranged above the feed path and extending transversely thereto, which has one or more rows of outlet openings on its side facing the feed path and with one Storage container for the glue is connected, and with a flat guide member arranged between the row or rows of the outlet openings and the feed path for the viscous glue liquid emerging from the openings.
  • German patent application P 36 12 973 describes a device for applying glue to wooden parts to be glued, consisting of a feed device for the wooden parts, a hollow body which is arranged above the feed path and extends transversely thereto and which has one or. On its side facing the feed path has a plurality of rows of outlet openings running in the transverse direction and is connected to a storage container for the glue. To form a uniform glue film, a guide plate for the glue liquid emerging from the openings is arranged between the row or rows of the outlet openings provided on the hollow body and the feed path of the wooden parts to be glued.
  • Turbulent air movement essentially caused by the air flow in front of the guide plate, when the wooden parts are brought up to the application device at a high feed rate, can lead to malfunctions, for example interruptions or short-term tearing off of the adhesive film.
  • the object was to take measures in a device for applying glue to wooden parts to be glued, of the type described at the outset, by means of which the glue film disruptions caused by air movement can be avoided.
  • the solution to the problem is that devices preventing air congestion are provided on the guide member and / or in the area of the guide member.
  • the device for applying glue consists essentially of the actual application element 1, a storage container 4 connected to it via a pump 2 and supply lines 3, and a feed device 5 located below the application element for the glue to be coated Wooden parts 6.
  • the application member is a cylindrical or hollow cross-section 7 which extends across the feed path of the wooden part 6 and has a round or rectangular cross-section, the side of which faces the feed path has one or more rows of outlet openings 8 in the longitudinal extension of the hollow body of bores or slots and is connected to the reservoir 4 via the pump 2.
  • the size of the openings 8 depends on the viscosity of the liquid emerging therefrom and the feed rate of the wooden part; it is usually between 0.5 and 5.0 mm.
  • the holding of the hollow body 7 can be carried out in a manner familiar and suitable to the person skilled in the art; it is therefore not shown or described any further.
  • a guide element in the form of a guide plate 9 made of metal or plastic is arranged below the openings 8 and extends along the row or rows of openings.
  • the glue impinging on the guide plate from the openings flows on the surface of the plate, so that a coherent and uniform film of glue is formed which flows from the guide plate onto the workpiece surface to be coated. If there are several rows of openings, the glue flows escaping from it are detected by the baffle plate in that it is angled or curved.
  • the resulting glue film Since the resulting glue film has a tendency to contract, it can be guided and stabilized at its edges. This can be done with the help of rigid or movable drain edges into which the baffle runs out to the side.
  • An interruption or tearing off of the glue film is avoided according to the invention in that an air build-up in front of the guide element is prevented by constructive measures on the guide element itself or in its area.
  • this is achieved by openings 13 of any shape, for example round openings (FIG. 2) or slots (FIG. 3) or comb-like recesses (FIG. 4) through which the air flow can pass.
  • the glue film on the baffle is divided several times through the openings, but then it flows together again.
  • a flat, net-like structure 14 for example a wire net (FIG. 5), or a guide surface formed from closely hanging chains or braids 15 (FIG. 6) can be provided.
  • a wire mesh or hanging chains next to each other as a guide are cheap because they can be brought very close to the wooden part to be glued and there is no damage to the guide when touching the wooden part. It is namely advantageous to bring the guide element forming the glue film as close as possible to the surface to be acted on, since the tendency for the glue film to tear off is less, the shorter the free fall of the same.
  • the openings 13 of the perforated guide plate 9 shown in FIGS. 2 and 3 or those of the wire mesh shown in FIG. 5 can have a width of 0.5 to, depending on the viscosity of the glue, degree of thixotropy, throughput of glue per unit of time and intensity of the air congestion 25 mm, the width of the recesses shown in FIG. 4 or the distances between the individual chains shown in FIG. 6, which are hanging in a row, are 0.5 to 25 mm.
  • a further possibility of avoiding an air congestion in front of the guide element is that the air flowing in the direction of advance of the wooden part, as shown in FIG is blown away by air flowing against the feed direction.
  • a further measure to avoid the air congestion is that immediately in front of the guide element 9 in the entire width of the feed path both above and below this brush 17 ( Figure 8) are attached, which are directed obliquely at an angle or wedge-shaped to the feed direction.
  • the brushes stop the air flow because they can be placed directly above the surface of the wooden part without hindering the feed.
  • the constructive measures described above can also be combined with one another, in particular those according to FIGS. 2 to 6 with those according to FIGS. 7 to 9 if a particularly good effect is to be achieved.
  • the hollow body 7 provided with outlet openings 8 for the glue is assigned a further hollow body which is provided with a guide plate and is connected to a storage container (not shown in the drawing).
  • a storage container not shown in the drawing.
