Definitions
- the invention relates to a method for applying adhesive to the narrow side of thin, film-like workpieces, in particular of veneer strips or sheets, wherein the workpiece and at least one adhesive substantially normal to the narrow side of the workpiece emitting nozzle are guided with a small distance from each other.
- This device generates by means of nozzle contactless continuously a thread-like cross-section of a glue rhombus, which is metered so that it does not swell when squeezing both edges. Also, it is difficult to match the instantaneous distance of the two workpiece edges in the nozzle area exactly the required bead thickness. After the order movement of the adhesive is not directly on the workpiece edges, but perpendicular to it on the support surface and only by merging the veneer edges, the adhesive is taken from the support surface by stripping, the adhesive can also be transferred to the veneer surface. It is also to be reckoned with an accumulating contamination of the support surface by the constant wetting with adhesive.
- the adhesive is already applied frontally, ie perpendicularly, to the veneer edge to be bonded by means of a nozzle.
- the objective is also addressed that when gluing veneers, it is important that neither before nor after pressing next to the edge to be glued on the later visible veneer surface adhesive leaks, and that at relatively high speeds, the veneers during the adhesive or glue application are moved past the nozzle device. Also guides are used in this device to achieve an exact positioning of the veneer edge during the adhesive application to the nozzle opening.
- the distance to the nozzle opening may vary. Due to the small dimension of the glue application, usually 0.2-0.3 mm with a veneer thickness of 0.5 mm, the distance should be very small. The narrow veneer edge may even touch the nozzle opening.
- the invention is therefore based on the object, a method for the application of adhesive of the kind described in such a way that even at high job speed and very narrow and wavy application edge a uniform, precisely positioned and precisely metered amount of adhesive is applied such that neither before nor after the pressing of adhesive overflows or swells out.
- Execution are suitable for the precisely dosed order (dosing accuracy approx. 2%) of adhesive droplets, since they are able to transfer a particularly high impulse to the usually higher viscous adhesives and are also suitable as a drive for very fast working needle nozzles.
- dosing frequencies of up to 1,000 Hz
- the requirements for high adhesive application speeds can be met in practice be met.
- With a veneer thickness of usually 0.5 mm only very small adhesive droplets of 0.1 - 0.3 mm are possible.
- Needle nozzles also offer the advantage, especially when applying glue, that the needle seals the nozzle opening tightly and thus prevents the adhesive from hardening and leaking.
- the high pulse in the piezoelectric drive of the droplets is advantageous to overcome the high adhesive forces or surface tension forces (adhesion forces), which occur in the microdosing of adhesives.
- Nozzle openings come into contact, they adhere and inevitably lead to problems in that adhesive builds up at the nozzle opening and there is no clean demolition of the drops more and in extreme cases, the nozzle can clog with thermosetting adhesive.
- guide elements in the application area are particularly important because the veneer edge in the application plane of the nozzle must be guided or centered absolutely free of play. Only then can the exact order position of the adhesive droplets advantageously be reached exactly in the middle of the edge. In addition to the exact order position, the dosage and the order frequency of the adhesive droplets can be used to precisely control the dosage. The aim is to apply as much glue to the edge as possible, so that the entire edge is wetted when pressed, but no glue will overflow.
- nozzles can be connected in series, so that one can either work with higher application speeds or one or several even rhombuses can be achieved in parallel by many small overlapping droplets.
- Fig. 1 shows schematically an application device of the adhesive droplets on a workpiece, shown in the side view of the planes of the order movement and in section.
- Fig. 2 also shows schematically the applicator, but in this case the
- contactless and metered in droplet form by means of one or more nozzles 1, adhesive droplets 2 on the strip-shaped surface, in particular the edge 4, thin, film-like workpieces are applied.
- the workpiece 5 is moved relative to the nozzle 1 in the direction 8, wherein the adhesive droplets 2 generated by the nozzle 1 touch after impact or overlap more or less, and thus a continuous and uniform Create adhesive diamond 3. Due to the order frequency of the adhesive droplets in relation to the order speed, but also by the
- Glue dots can be created with any spacing.
- Fig. 1 the guide elements 6, 7 are shown schematically in plan view.
- the workpiece 5 is guided or centered absolutely free of play in the application plane of the nozzle 1 at the time of the impact of the adhesive droplets 2.
- the exact application position of the adhesive droplets advantageously be achieved exactly in the middle of the application edge 4 during the application movement in the direction 8. Due to the high airspeed of the droplets 2, even with irregular workpiece edges it is ensured that it is stable Order results comes, especially when the distance of the nozzle 1 to
- Suitable adhesives are all materials that are tried and tested in the gluing of veneers, which can be applied in the form of metered drops.
- Reactive hot melt adhesives based on polyurethane have proven particularly suitable.
- Microdosing in particular those with piezo drive, with which the inventive method is feasible, are offered by various manufacturers, for example by the company PICODOSTEC GmbH.
- the novel adhesive bonding technique according to the invention has already led to a new field of application for veneer sheets of stub-glued strips:
- the proposal to provide honeycomb core sheets with single layers of solid wood, has so far found no input into practice, since only relatively thick and therefore expensive plates glued together were.
- veneered plywood panels were used as the top layer.
- the invention makes it possible to make the mutual connection of the veneer strips so strong that the thickness of the cover layer is limited only by its static function downwards.
- honeycomb core plates are economically interesting, whose cover layers are constructed only of mutually blunt glued strips of saw veneer.
