Definitions

  • the supply of the material is interrupted at certain intervals.
  • the device which conveys viscous material to the nozzle, can not be switched in the same cycle for inertial reasons. This results in the supply of viscous material to a pressure build-up, although the supply is interrupted, but the conveyor continues to promote.
  • the pressure build-up can be regulated by a bypass channel, so that after a certain pressure, the viscous material flows back through this bypass channel from a nozzle chamber, for example, into a storage tank.
  • this method can not be controlled sufficiently fine, so that said effect can not be completely eliminated.
  • This fluctuating pressure curve is also reflected in the application image of the viscous material, since when the valve is opened, an increased pressure in the nozzle chamber is present and thus more viscous material emerges from the nozzle until the pressure conditions have adjusted again.
  • a uniform distribution of the viscous material and exact edges at the beginning and end of a job should be possible even when intermittent order.
  • a high accuracy during the application both over the entire application width and in the transport direction of the substrate is to be achieved in addition to precise purchase and sales edges.
  • the invention is based on the idea, in addition to the known supply control for the viscous material, the
  • the volume of the nozzle chamber is arranged as close as possible to the nozzle opening.
  • the volume control of Nozzle chamber is preferably by means of a deflectable
  • Achieved membrane or piston which is controlled by a pressure source or excludeienkt.
  • the membrane or the piston extends over the entire order width to be controlled.

  • a substrate 1 is conveyed by means of a transport device 2 to the nozzle 3 in the application direction
  • a detector unit 7 arranged in front of the nozzle in the direction of transport T recognizes the markings 8 in the substrate 1 and supplies detector signals to the control unit 9. With knowledge of the markings 8 and the transport speed of the substrate 1, the control unit 9 controls the control unit 14 and / or the pressure control unit 11 over the lines 10.
  • the pressure control unit 11 which is arranged on the application head 5 in a preferred embodiment, is controlled by a pressure source 18 and can change the pressure of the viscous material 12 in the region of the nozzle chamber 15, which will be explained in more detail with reference to FIG. More preferably, the pressure control unit 11 is as close as possible to the nozzle opening, i. the opening of the nozzle 3, at which the viscous material emerges and is applied to the substrate 1, is arranged.
  • the application head 5 and / or the pressure control unit 11 are controlled directly by the detector unit 7, or controlled without detector unit by means of preset signals.

  • FIG. 2 shows a side view of a preferred embodiment of an application head 5, wherein the view has been cut so that the function of the pressure control device 11 is illustrated.
  • the viscous material 12 is supplied via a pipe or a hose 13 to the application head 5, where a control device 14, for. B. in the form of a controllable valve, for controlling the supply and for interrupting the supply of the viscous material 12 is arranged.
  • the pressure control device 11 arranged downstream of the control device 14, viewed in the direction of flow of the viscous material, regulates the pressure of the viscous material 12 in the region of the nozzle chamber 15 of a nozzle 3. In a preferred embodiment, this is achieved with a deflectable membrane 16 which forms part of the wall of the nozzle chamber 15 forms.
  • the membrane 16 is deflected in one of the two directions as needed.
  • the pressure of the viscous material 12 can be acted upon positively or negatively by changing the chamber volume, whereby a fine control of the material application is made on the substrate 1.
  • the pressure control device 11 is arranged near the outlet opening of the nozzle, since so less viscous material has to be moved in the control. This is advantageous on the one hand with regard to the required control force of the diaphragm and on the other hand for the speed and thus also for the accuracy of the control.
  • the membrane extends substantially over the entire width of the surface application nozzle.
  • the membrane is controlled by one or more ports in which the fluid for the deflection of the membrane is supplied or sucked.
  • a piston is used in the pressure control device 11 instead of the diaphragm 16, which performs the desired change in volume in the region of the nozzle chamber 15.
  • a membrane 16 is deflected so that deviations from the desired material pressure are compensated.
  • the control device 14 and the valve When terminating the application of viscous material 12 to the substrate 1, the control device 14 and the valve is closed and retracted at the same time or offset the rest of viscous material 12 remaining in the region of the nozzle chamber 15 so far that a distance between viscous material 12 and Substrate 1 is formed. This ensures that, despite the cohesive forces of the viscous material 12, the heel edge is formed exactly.
  • at least two pressure control devices 11 are present per control device 14, preferably arranged side by side relative to the transport direction T in the transverse direction.
  • Figure 3 shows schematically the area of the opening of a nozzle 3 terminating the application of viscous material 12 to a substrate 1.
  • the viscous material 12 has been withdrawn from the pressure control means 11 by a distance between viscous material 12 and substrate 1 produce.
  • Fig. 4 shows a membrane 16, wherein below the membrane 16 viscous material 12 and above a fluid 17 are.
  • the membrane 16 is shown in the upwardly curved state, as z. B. may be 12 when the order of the viscous material is completed, since viscous material 12 is withdrawn from the region of the opening of a nozzle 3, as shown in Fig. 3.
  • the deflection of the diaphragm 16 is achieved by controlling the pressure of the fluid 17. When the control device 14 is closed, this results in a distance between the viscous material and the substrate 1 (FIG. 3).

Abstract

La présente invention concerne un dispositif d'application intermittente de matériaux visqueux au moyen d'une buse (3) sur un substrat (1), comprenant un dispositif de transport (2) pour produire un mouvement relatif dans le sens de l'application entre le substrat (1) et la buse (3) et un dispositif de commande (14) pour commander et interrompre l'arrivée du matériau visqueux dans la chambre (15) d'une buse (3). Le dispositif est caractérisé en ce que le dispositif de commande (14) présente un dispositif de commande de pression pour commander la pression du matériau visqueux dans la chambre (15) de buse et/ou pour modifier le volume de la chambre (15) de buse. La présente invention a pour objet la mise au point d'un dispositif amélioré et d'un procédé amélioré d'application de matériaux visqueux sur un support. Elle doit notamment permettre, même dans le cas d'une application intermittente, de réaliser une distribution homogène du matériau visqueux et des bords précis au début et à la fin de l'application.
