Definitions

  • viscous media is meant liquid media such as paints, varnishes, and especially adhesives.
  • fluid media is meant non-liquid, but deliverable via alongeddüse materials, in particular flowable solids such as magnetic or nanoparticles.
  • the adhesive is fed regularly under preselected pressure and preselected temperature via a valve of a application nozzle.
  • This valve is usually designed to be driven electrically or electropneumatically and is also referred to as "order valve".
  • the maximum achievable clock frequency of the valves is limited due to the system.
  • the power supplied to the coil of the electromagnet at each cycle must be increased in order to increase the clock frequency.
  • this power is limited, depending on the design and size of the coil, since the power loss increasing with increasing power leads to a heating of the coil, which in extreme cases can result in destruction of the coil.
  • even less heating of the coil can lead to an undesirable increase in the temperature of the medium to be applied, making it useless by decomposition or - in the case of an adhesive - could be clogged by premature curing the application nozzle.
  • the maximum achievable clock frequency is also regularly limited by the medium itself upwards.
  • the medium For in a variety of known order valves of the anchor to which the application nozzle opening and closing nozzle needle is coupled, surrounded by the medium to be applied. With increasing viscosity and viscoelasticity or decreasing flowability, the medium therefore opposes the movement of the armature increasing resistance, so that reduces the maximum achievable clock frequency.
  • media such as high-viscosity adhesives therefore a desired fast point sequence in order lines can not be achieved.
  • the invention is therefore based on the object to provide a method and an apparatus with which viscous or fluid medium can be delivered, inter alia, with a higher clock frequency.
  • the method according to the invention provides that the at least one viscous medium is fed via at least one first and one second feed to a common application nozzle. Due to this measure, the clock frequency can be doubled, for example, when synchronized alternately via the first and the second feed via the application nozzle the medium to be dispensed is supplied with the respective technologically conditioned maximum clock frequency of the application nozzle. In this way - at otherwise constant conditions - the production speed can be at least almost doubled. Or it is possible, for example, if the production speed is not increased, to deliver even finer interrupted order lines to the substrate.
  • the two feeders are regularly supplied with the same medium.
  • the method according to the invention is not limited to exactly two feeds, with which viscous or fluid media are fed to a common application nozzle, but also extends to a plurality of feeders, via which media are supplied to the common application nozzle.
  • the device according to the invention for applying at least one viscous or fluid medium to a substrate comprises a nozzle body with at least one nozzle channel, a first valve, with which the viscous or fluid medium can be intermittently delivered to the nozzle channel, and at least one second valve, with which viscous or fluid medium intermittently on the same nozzle channel can be issued.
  • the synchronized alternately clocked operation of the first and second valves, the frequency with which a medium is applied intermittently, and thus, if necessary, the production speed can be increased.
  • the first and second valves may be arranged in a V-shape inclined to each other by an inclination angle.
  • the nozzle channel is then approximately in the region of the intersection of the two legs of the V, so the spatial dimensions of the device can be minimized in the region just above the substrate, which facilitates their installation in production facilities.
  • a third and fourth valve with which viscous or fluid media can be dispensed intermittently to the nozzle channel.
  • the clock frequency at which the medium is discharged from the nozzle channel, and the device is not limited to the delivery of the components of a two-component system.
  • the third and fourth valve are also V-shaped inclined to each other at an inclination angle, such that the plane of this V-shaped arrangement perpendicular to the plane of the V -shaped arrangement of the first and second valve extends.
  • valves can basically be designed in any way with regard to their drive.
  • electrically operated valves such as those in which the actuation of the opening and closing of the valve causing the nozzle needle is electromagnetically, use, as with these higher clock frequencies than, for example, with electro-pneumatically driven valves can be achieved.
  • Each valve can be connected to its own supply device for the supply of viscous or fluid media.
  • the device is then particularly variable in terms of their use for multi-component application systems.
  • temperature control means are preferably provided with which the viscous or fluid media can be individually tempered so as to be able to deliberately apply, for example, various components having the optimum temperature or one and the same hot glue with a temperature gradient or temperature-layered.
  • the device preferably comprises a control / regulating device, by means of which the valves and their associated conveyors for supplying the viscous or fluid media are controlled or regulated.
  • first embodiment of the device for applying at least one viscous or fluid medium to a substrate 1 comprises a nozzle body 2, which has a nozzle channel 3 shown in dashed lines, the free, the substrate 1 facing the end of a application nozzle 4 forms ,
  • first application valve 5 and a second application valve 6 Attached to the nozzle body 2 are a first application valve 5 and a second application valve 6, which are designed as conventional, electromagnetically actuated application valves and with which fed, viscous or fluid media intermittently to a first supply 7 and to a second supply 8, both in open the nozzle channel 3, can be dispensed.
  • the first and second application valves 5, 6 are operated intermittently and synchronized in time with a control / regulating device, not shown in the drawing, so that by means of the device 100 on the in the feed direction V at the application nozzle 4th transported substrate 1 a broken order line 9 is applied.
  • the first and second application valves 5, 6, which comprise temperature control means for controlling the temperature of the media to be applied, are arranged in a V-shaped manner inclined to one another at an inclination angle ⁇ .
  • second embodiment 200 of the device according to the invention differs from the embodiment 100 in that a third order valve 10 and a fourth order valve 11 are additionally provided. These order valves are inclined in a correspondingly large angle of inclination V-shaped to each other as the first and second application valves 5, 6, such that the plane E2 perpendicular to the plane E1 of the V-shaped arrangement of the first and second valve 5, 6 extends.
