Definitions

  • the present invention relates to a device for applying flowable or rendered materials, in particular of Adhesives, paints or varnishes or release agents.
  • Devices of the type mentioned are known and are e.g. used to apply portions of glue to a substrate.
  • the application of the glue is controlled via the metering valve, whereby in particular a punctiform application is possible.
  • suitable Dosing valves are for example in DE 40 13 323 C2, DE 91 15 872 U1 or DE 295 08 916 U1.
  • These metering valves generally have a continuous, one-piece Dosing piston, which is part of an electromagnet through which the Dosing piston can be pulled up.
  • a spring can thus in particular by the optionally switchable magnet pulsating drive of the dosing piston.
  • the object of the present invention was to overcome the disadvantages of the prior art to avoid the art and a device for applying to provide flowable or rendered materials, at which disruptions due to inaccurate positioning of the Dosing valve, fluctuations in the product run or contamination of the Dosing valve outlet opening can be avoided.
  • a device containing a carrier and a metering valve connected to the carrier which thereby is characterized in that a below the nozzle outlet opening Support device for the product to be coated arranged in this way is that it lies against the nozzle outlet opening and below the Contact area of the product to the nozzle outlet opening System pressure of the metering valve can give way.
  • the support device is preferably designed so that it is below the nozzle outlet opening has at least one recess.
  • the Geometric design of these recesses is in any Shapes possible.
  • the shape of the cutouts is preferably such designed that the transitions to the contact surfaces no corners and Have edges. This means that the recesses are similar to a river bed designed.
  • Recesses are accordingly preferred according to the invention, which are U-shaped or V-shaped. V-shapes are particularly preferred.
  • the areas surrounding the recesses are preferably as Contact surface switched off. This is preferred according to the invention arranged and shaped so that the product to be coated Above the cutouts, it fits the nozzle outlet opening precisely can be created. These are preferably the recess surrounding areas designed so that the product to be coated with the side facing away from the nozzle outlet opening on this plane or approximate plan.
  • the support device can, for example, also consist of two parts comprising the support surface.
  • several parts with a contact surface can also be used according to the invention.
  • a part is preferably arranged between the segments. This part is designed in such a way that a recess is created between the segments.
  • the shape of the part located between the segment is according to the invention by the design of the adjacent Segment areas determined.
  • the part can also assume such configurations that e.g. U or V shaped Cutouts arise.
  • An embodiment is preferably too choose that the transition between recesses and contact surface has as few edges and corners as possible.
  • the inventive arrangement of a support device in the described embodiments under the nozzle outlet opening allows a wider range of variations when setting Adjustment tolerances, especially with regard to the height of the valve.
  • the Support device ensures due to its special shape an even back pressure of the product to be coated against the application valve.
  • the principle of the invention is namely that to give the product downwards over its entire width capable and does not get stuck under the valve. simultaneously the internal tension in the product ensures an even pressure the nozzle outlet opening of the valve and ensures contact regardless of the exact setting height of the valve within the Tolerance range.
  • the products to be coated also do not jam or jam in the machine if the metering valve is triggered one or more times and adhesive emerges without there being a product to be coated underneath.
  • the device according to the invention is preferably used for coating of products with flowable substances, in particular of Adhesives, paints or varnishes.
  • Adhesives e.g. re-moistenable rubber glue, Fugitive adhesives, pressure sensitive adhesives.
  • the products to be coated are made of any materials. Paper, wood, plastics and metals can be considered.
  • the use for coating is particularly preferred according to the invention of paper and cardboard, preferably for the application of adhesives.
  • the metering valve is arranged directly above a shaft 9.
  • the product 4 is fed in the product running direction 7 and is guided between the shafts 10a and 10d into the gap 11 between the nozzle outlet opening 2 and the shaft 9.
  • the product 4 passes through the gap 11 via the shafts 10b and 10c into the further processing process.
  • a disadvantage of this device is that the shaft 9 can easily stick if adhesives emerge from the nozzle outlet opening 2 without the product 4 being underneath.
  • the height adjustment of the metering valve 1 may damage the surface of the shaft 9.
  • the setting of the distance 11 is decisive for the contours and tear-off surfaces of the coating material. This is especially true when applying adhesives. Compensations must be created here by adjusting the height or the distance 11 in the vertical and horizontal directions and the angle of inclination of the metering valve 1.
  • Fig. 2 the metering valve 1 with an embodiment of the one below arranged support device 3 shown.
  • the support device 3 has a V-shaped recess 5. This recess is immediate arranged under the nozzle outlet opening 2 of the metering valve 1.
  • This in The product 4 fed in the product running direction 7 is between the edition 3 and nozzle outlet opening 2 passed through.
  • Product 4 is subject to the attachment to the Nozzle outlet opening 2 of a slight tension. So that is achieved that the product 4 in the area lying above the recess 5 in can yield its entire width and therefore not under the Dosing valve 1 can jam.
  • the internal stress in the Product 4 due to the support on the surfaces 6a and 6b for one even pressure on the nozzle outlet opening 2. This is a Contact regardless of the setting height of the metering valve 1 within guaranteed a tolerance range.
  • FIG. 3 shows a variant of the support device according to the invention with support surfaces 6a and 6b.
  • a part 8 that can be exchanged according to the width of the order. This area corresponds to the recess 5 in FIG. 2. If the nozzle outlet opening 2 is at the level of the dashed line 9, unintentionally escaping liquid cannot collect or deposit in the recess of the support device 3.
