Abstract

The invention relates to a method for fixing a mounting (12) to a derived timber product (4). According to said method: the contact area of the mounting is at least partially provided with an adhesive; the contact area of the mounting is then brought into contact with the derived timber product; the adhesive is inductively heated and activated by means of magnetic induction, and; an adhesive connection is created by the hardening adhesive, between the mounting and the derived timber product. The invention also relates to a component produced according to said method.

Description

Component with wood element and hardware adhered thereto and manufacturing method thereof
Technical Field
The invention relates to a part consisting of a wood element and a hardware part bonded thereto. The invention also relates to a method for gluing hardware and wood elements together.
Background
The wood element according to the present invention means an element made of natural wood, a single part made of natural wood, or a material made of natural wood. The element consisting of a single piece made of wood may be, for example, a wood panel. The material made of wood may be Medium Density Fiberboard (MDF), High Density Fiberboard (HDF), hard fiberboard, particle board or Oriented Strand Board (OSB).
In the prior art, parts containing wood elements are often provided with metal fittings (such as handles or hinges). Especially on furniture parts or doors. The connection between the component and the fitting is usually made using mechanical fastening methods, in particular screws for fastening the fitting to the surface of the wood element.
However, there are some parts which are not constituted by a solid layer of wood material, but only by a layer of wood material of small thickness, which makes it difficult or impossible to screw them in. In these cases, it is necessary to fix the hardware fitting in some other way, in particular to glue it to the component.
The gluing process is however relatively complex, and in particular the application and hardening of the glue and the positioning between the hardware and the wood element require a number of processes. This makes the adhesives which require heat to activate problematic in use due to the heat required for processing, as any wood material will discolor at too high a heating temperature.
Disclosure of Invention
The object of the invention is to improve the method and the components described at the outset in such a way that the bonding process with hot-melt adhesives is simplified and the quality of the adhesive bond is improved at the same time.
The above-mentioned object is achieved according to claim 1 by a method for gluing a fitting to a wood element, wherein the joint surfaces of the fitting are at least partially coated with an adhesive and the joint surfaces of the fitting are brought into contact with the wood element, wherein the fitting or the adhesive is heated by magnetic induction before or after the contact is made, wherein the adhesive is heated and activated by the heat generated, and wherein a glued joint is formed between the fitting and the wood element by hardening of the adhesive.
The method has the advantages that: the adhesive is first applied to the hardware fitting or prior to the gluing with the wood element. The adhesive in the cooled state has no or only a weak adhesive effect if it is not heated. The adhesive should only produce a bond force when the adhesive-coated faying surface is about to contact or has contact with the surface of the wood element.
The advantages of the method are therefore particularly suitable for industrial use, since the adhesive can be applied to the hardware before it is shipped and only then has to be heated in situ when the wood elements are used for treatment. Wherein only hardware or glue is heated in an induction mode, and the heating degree of the wood element is extremely small, so that the wood element is particularly beneficial.
For this purpose, either before or after the contact, the metal fittings or the adhesive are heated by means of a magnetic induction heating source. The magnetic induction heating mode has the advantages that: only the electrically conductive parts of the hardware or the glue are heated, without the heat radiation having to be generated. Only the hardware or the adhesive is therefore heated first by magnetic induction, while the wood elements are not heated. This activates the adhesive and releases its adhesive strength.
By contact with the adhesive, and the small amount of thermal radiation emitted by the hardware or adhesive, heat is also transferred to the wood material, but not beyond the temperature limit that can discolor, burn or char the wood material. After a short heating, the adhesive can cool down rapidly, so that the heat transferred to the wood material does not have a negative effect on the wood material elements.
The electrical conductor can be inductively heated by means of a magnetic induction by means of a device which generates an alternating magnetic field by means of a coil to which an alternating current is applied, which alternating magnetic field in turn induces an alternating current in the electrically conductive element. Due to the presence of the resistor in the element, the induced current in the element heats the element at the location where the current passes. This immediately generates heat inside the component and does not require heat to be transferred to the component by thermal conduction.
Non-conductive materials, in particular wood materials of the type mentioned above, are not heated by induction. In addition, a material having good conductivity, such as aluminum or copper, is hardly heated due to its extremely small electric resistance. Metals suitable for induction heating all have a relatively large electrical resistance.
An apparatus suitable for carrying out this method is disclosed in DE20300624U 1. This is a handheld device that can be used for induction heating. Of course the invention is not limited to the use of hand-held devices. Stationary devices may also be used in industrial applications, such as furniture production.
The fitting is preferably made of a material which can be heated by magnetic induction and which can be heated by magnetic induction. The heat generated in the hardware fitting is transferred to the adhesive. Preferably the hardware is made of metal, although conductive plastics or plastics containing conductive particles may be used.
The adhesive may also be electrically conductive and may be heated by magnetic induction. In this case, heat will be generated directly in the adhesive, i.e. just where it is desired to activate and harden the adhesive.
In addition, the adhesive, which is not electrically conductive per se, may also contain electrically conductive particles which can be heated by magnetic induction. For example, the adhesive may contain metal particles or metal chips that can be heated by magnetic induction and can emit heat to the adhesive. This can generate heat at the very point where activation and curing of the adhesive is required.
There are many designs for adhesives. The requirements for the adhesive are as follows: the adhesive can be brought into an activated state by means of the input of heat, so that the adhesive, after cooling, is brought into a bonding state, whereby the hardware fitting and the wood element are joined together.
It is preferred to use a reactive adhesive and to pre-crosslink the adhesive at least partially before the fitting is mounted on the wood element. The adhesive is finally hardened after heating. Reactive adhesives can be classified into polymerization adhesives, polyaddition adhesives, and polycondensation adhesives. Reactive adhesives can therefore be distinguished by the type of chemical reaction.
All these reactive adhesives have the common property that they do not react or react to a very small extent at room temperature and only react chemically after they have been heated by the input of heat. These reactive adhesives are also known as heat-cured or high-temperature-cured adhesives. It is preferred to use reactive adhesives which only require a small temperature rise to allow chemical reaction. Therefore, heat-curable reactive adhesives are most suitable.
In a further embodiment of the method, a thermoplastic adhesive is used and is at least partially cured before the fitting is mounted on the wood element. It is then activated, in particular liquefied, at least locally by heating, so that it bonds well to the surface of the wood element and can form a glue joint after the glue has cooled.
In a further preferred embodiment of the process, a multi-component adhesive is used. One part of the adhesive is a thermoplastic adhesive and the other part is a reactive adhesive. Such adhesives are also known as reactive hot melt adhesives (RHMs).
In addition, the wood element surface may be pretreated by roughening, grinding, smoothing and/or other methods and/or coated with a primer or other products for surface coating pretreatment prior to installation of the hardware.
In particular, it is possible to pretreat the coatings of the wood elements as described above at the points to be bonded and/or to remove these coatings locally or completely.
The above-mentioned object is also achieved by means of a component having the features of claim 7. Further preferred embodiments of the component are set forth in the dependent claims.
The component according to the invention has at least one wood element and at least one hardware fitting connected to the wood element. The adhesive layer is located between the wood element and the hardware wherein the adhesive joins the hardware and the wood element together. The inventive fitting or adhesive layer can be at least partially electrically conductive.
Hardware refers to any element that can be combined with a wood element. For example, the hardware fitting may be a hinge, a handle, a hook, a shackle, a lock, an end cap, in particular a table foot, or an accessory without any specific technical function.
Preferably, the hardware is made of at least one electrically conductive material. Hardware fitting just can heat oneself through the magnetic induction mode like this. Preferably, metal is used as the conductive material, as is plastic which is itself conductive or contains a plurality of conductive particles.
In addition, the adhesive layer may be composed of at least one conductive material. On the one hand, the electrical conductivity of the adhesive layer can be produced by means of adhesives having electrical conductivity. On the other hand, the conductivity of the adhesive layer can also be produced by a plurality of conductive particles contained in the adhesive.
The invention is particularly applicable to lightweight structural panels with or without a frame structure, wherein the wood elements have at least one outer cover sheet. Such parts are not structurally strong enough to reliably join hardware and wood elements by mechanical means, such as screws. As the components do not contain sufficiently strong material to allow the screws to form a strong connection. Furthermore, the wood elements preferably have an untreated surface. This ensures a good and reliable adhesion to the surface.
In another embodiment of the invention, the surface of the wood element is provided with a coating, in particular a paint layer, a laminated plastic layer, a melamine resin coating, plywood, preferably oiled or waxed, or a film coating. In this case, the hardware is bonded to the coating. Important preconditions for permanently fixing hardware fittings are: the coating should have sufficient adhesive capacity to be able to transfer the transmitted forces or tensions to the wood element.
Furthermore, the coating can be pretreated and/or primed with a primer or other product for pretreatment by roughening, grinding, smoothing and/or other methods prior to installation of the hardware fitting. In particular, these coatings can be removed locally or completely at the points to be bonded.
Of course all the above-mentioned pretreatment methods can also be used on wood elements either individually or in combination.
The above components and methods will be described in detail below with reference to the embodiments shown in the drawings, respectively.

Detailed Description
The different stages of the process flow for manufacturing the component according to the invention are illustrated in detail in figures 1 to 3 according to a preferred embodiment.
The component 2 has a wood element 4 of light construction. In which there is a sandwich layer 6, on both sides of which wooden panels 8 and 10, respectively, are laid. The sandwich layer may be of honeycomb construction, for example of cardboard or aluminium. The wooden plates 8 and 10 are thin, and the hinge-type hardware 12 cannot be fixed to the wooden plates 8 and 10 with screws.
The hardware 12 is thus bonded to the surface of the upper wood element 8 and the hardware 12 is heated during the bonding process by means of magnetic induction according to the invention. Hardware fitting 12 is constructed of a conductive material, such as metal.
As shown in fig. 1, the wood element 4 and the hardware fitting 12 are arranged at a distance from each other at the beginning. On the downwardly directed contact surface 14 of the fitting 12 there is a coating 16 of an adhesive which is dimensionally stable and has little or no adhesive bonding.
As indicated by the arrows in fig. 1, the hardware fitting 12 is brought into contact with the surface of the wood element 4.
Electromagnetic radiation is then applied to the fitting 12, as shown in fig. 2, and the fitting 12 is inductively heated at least in the region of the joining surface 14. The locally generated heat activates the adhesive, thereby allowing it to regain its adhesive force. The wavy lines and the wide arrows in fig. 2 represent electromagnetic radiation.
The means for generating electromagnetic radiation are not depicted in fig. 2, as the invention does not relate to such means. Hand-held devices or stationary devices may be used. In other words, the method of the present invention can be used for both industrial and automated mass production and single piece production.
Fig. 3 shows the final hardened part, in which the wood element 4 has been fixedly glued together with the fitting 12. Fig. 3 also shows that: the fitting 12 is fixedly attached to the other member 18 at other locations using conventional screws 20.
Fig. 4 shows an alternative embodiment of the wood element 4, and also shows the hardware fitting 12 glued together with the wood element. The wooden panel 8 and the sandwich layer 6 are each hollowed out within a range corresponding to the size of the hardware 12. The hardware fitting 12 is bonded to the wood panels 10 and 8 by a coating 16. The specific bonding process is the method described above.
In particular, the thickness of the hardware 12 can be adjusted such that the outer surface of the hardware 12 is flush with the outer surface of the wood panel 8.
It is also possible to use coating 16 to bond a second part of fitting 12 to another element, such as door 18. In this case, the bonding can also be carried out by the method of the present invention described above.
The hardware 12 is first brought into contact with the wood element 4 and then electromagnetic radiation is applied to the hardware 12. The advantages of this approach are: the hardware fitting 12 and the adhesive are heated inductively when the wood element 4 has been contacted. This facilitates the positioning of the fitting 12 on the surface of the wood element 4, since there is no or only a little gluing force and the surface contact can be released again or the fitting 12 can be moved over the surface of the wood element 4.
It is also possible to first inductively heat the hardware fitting 12 before contacting the wood element 4. In this case, the adhesive will only contact the surface of the wood element 4 after the adhesive has been at least partially activated.
