Definitions

  • the invention relates to a glue pot for a Kantenleimmaschine with a glue head, the interior of which opens outwardly via an exit slot, and arranged outside the glue head in front of the exit slot applicator roll, wherein between the applicator roller and the outlet slot, a rotatable metering rod is arranged.
  • the adhesive flows e.g. from a parent funnel down with gravity.
  • Glueing basins are known from the prior art in which the glue from above is fed by gravity to the glue head.
  • This glue pot usually have next to an applicator roll a dosing for dosing the adhesive with rotating applicator roll.
  • the roller is designed both for a rotation in synchronism with the direction of movement of the workpiece and for a rotation in the opposite direction to the latter, it is known to provide two dosing rods. Leakage of the adhesive when the roller is stationary is prevented by applying a metering edge of the corresponding metering rod directly to the applicator roll.
  • the applicator roll and the metering rods thus form together with the glue head a constructive unit that is difficult to dismantle and only by specialized personnel. This is particularly the case with the use of adhesives, which entail increased cleaning and maintenance, such as e.g. with reactive PUR adhesives, a big disadvantage.
  • Document DE4216191 relates to a machine for coating elongate workpieces in a continuous process, comprising a coating device for applying a hotmelt adhesive layer to a coating material, a hot melt adhesive chamber arranged in the application device, an applicator roll scooping from said hot melt adhesive chamber, and a layer thickness on the applicator roller determining metering device.
  • the invention has for its object to provide a glue pot with structurally simple means in which a
  • Leakage of the adhesive is prevented regardless of the applicator roll at a standstill and accurate metering of the adhesive during operation with a high degree of automation is possible.
  • the sealing of the glue head is achieved at standstill of the applicator roll with only one dosing.
  • the applicator roll can be easily disassembled and reassembled, which is necessary in particular when using PUR adhesive for frequent cleaning. It is achieved a full-surface seal between dosing and glue head, which is guaranteed at all adhesive temperatures.
  • the glue pot according to the invention is easy to disassemble and thus easy to maintain for the use of different adhesives.
  • the simple use of replacement parts is possible, which can only be used with certain adhesives, such as e.g. the applicator roll.
  • the dosing rod can also be easily adjusted in both directions of rotation to allow precise metering of the glue application when the applicator roll is moved in synchronism with or in opposition to the workpiece.
  • the adjustment can preferably be set by a control device as a function of operating parameters that are stored in a memory. Because the setting of the dosing rod can be independent of other elements, the integration of the control of the metering rod in an automation is easy.
  • the control device may also be based on default parameters for the exact position of the metering rod and other operating parameters of Kantenleimmaschine, eie. determine the thickness of the board, the feed rate, etc., the amount of adhesive, the determined amount of adhesive can be used for further automation steps or for the "Lerfahren" of the glue head is required when closing a funnel or a supply channel, so that no unneeded adhesive must be disposed of.

  • the heat-insulating intermediate layer 22 rests on a rectangular PUR supply device 14.
  • a horizontal supply channel 27 is formed, which opens into a vertical passage opening 29 in the PUR supply device 14.
  • the passage opening 29 is aligned with the passage opening 25 and the outlet opening 21 of the funnel 12.
  • the supply passage 27 is sealed by a threaded screw 31.
