  • the adhesives used are hotmelt adhesives such as polyurethane (PUR), amorphous poly-alpha-olefin (APAO) or ethylene-vinyl-acetate (EVA), which are supplied in block form or as granules. In melters, these adhesives are melted and liquefied.
  • Tank melters are known, or piston melters such as the VSK40 from Delle Vedove, which melt adhesives in an adhesive duct and feed them to an adhesive application unit, such as a roller or a nozzle.
  • Such pre-melter are separate units in which a piston presses on the unmelted adhesive, and from which via a pump and via hoses the adhesive is supplied to the glue application unit.
  • the pump, the hoses and the glue application unit must be kept at the same level as the processing temperature
  • Glue be kept. This can only be achieved by means of elaborately controlled heating circuits, so that a decomposition of the adhesive is avoided. From WO 00/02667 a nozzle assembly with built-in electric heater is known.

  • a heating grate which is supplied for melting with electrical energy, granules is introduced, the heating grate is completely enclosed.
  • In the container there is a rotatably mounted pressure plate which presses on the solid adhesive and thus accelerates the melting process. Due to the rapid melting of the adhesive under pressure, the heating grate is cooled, and there is no local overheating.
  • the molten adhesive collects on the bottom of the container.
  • a heater is integrated, which holds the collected adhesive regulated at a temperature above its melting point.
  • the control unit ensures a constant temperature.
  • the molten adhesive is delivered from the container via a pump to the nozzle application unit. Since the pre-melt container, the glue pump and the filter housing of the nozzle application unit are directly connected, the same heater also acts on these components. Additional regulated heaters for these components are not needed.
  • For rapid melting of the solid adhesive is applied to the axis of rotation of the pressure plate from the outside, a defined compressive force on the adhesive.
  • the end position of the printing plate is detected by a sensor, such as a limit switch, and reported to the controller and the operator.

The end position is reached when the solid adhesive is completely liquefied. Then the heating energy of the heating grate is switched off and the pressure plate is rotated back to its original position. So that the pressure plate compacts only unmelted adhesive in solid form on the heating grate, it is provided with slit-shaped openings through which liquid adhesive can flow.

Since the container bottom and the heat-conducting block 17 are connected in a heat-conducting manner, the electric heater 5 can be arranged either in the container bottom or in the adjacent region of the heat-conducting block 17 or between them. Likewise, the temperature sensor 18 may be disposed in the ground or in block 17.

  • Fig. 4 the melter is shown so that the adhesive 14 is completely liquefied and the pressure plate 2 is rotated back to its initial position. The electrical supply heating grate 4 remains switched off. The container 1 can now be loaded with new solid adhesive.

Abstract

La présente invention concerne un système de fusion d'adhésif comprenant une unité de fusion et d'application à filière (10, 12, 15) conçue pour faire fondre et pour appliquer ensuite un adhésif sous forme de granulé ou de bloc (7). Le système de fusion selon cette invention est constitué d'un récipient (1) comprenant un couvercle hermétique (3), une grille de chauffage électrique chauffée (4) et une plaque de pression (2), ainsi que d'un chauffage par le fond (5) à régulation de température électrique. Une pompe (10) pour l'adhésif fondu, un filtre (15) et un porte-filière (12) comprenant une filière plate sont placés après le système de fusion. La pompe (10) avec le filtre (15) qui est raccordé directement côté sortie (15) et le porte-filière (12) qui y est directement raccordé sont montés de manière compacte dans un bloc thermoconducteur (17). Un orifice d'évacuation de fond (11) du récipient (1) débouche dans ce bloc thermoconducteur, côté raccord de pompe. Ce bloc thermoconducteur est relié sur toute sa longueur et de manière étendue au fond à chauffage thermostatique du récipient (1).
