    专利说明:

    The present invention relates to a Kantenanleimvorrichtung for plates.
    More particularly, the present invention relates to an edge banding apparatus for applying a strip edge trim (" lipping ") member to the narrow edge of a wood-based, metallic, and / or plastic panel.
    Edge banding devices are already known today which are equipped with a gas or hot air heater which serves to expose a surface of the edging strip to air jet or high temperature pressurized gas to activate the adhesion of the strip to the narrow edge of a plate ,
    A problem with these conventional devices is that, in order to achieve the effective adherence of the edge strip to the plate, a reasonable amount of heat has to be applied to the strip or the adhesive with which it is coated in a short time this heat is lost again before the strip is connected to the edge.
    In fact, these conventional devices provide for incremental advancement of the plate and the strip to be applied thereon.
    The feed rates are high to maintain high production rates.
    The gas powered heater is bulky and therefore located away from the area where the connection between the strip and plate edge occurs.
    In order to achieve that the hot air is discharged in this connection region, such a conventional heating device is provided with an insert which is arranged between the strip and the plate edge and as close as possible to the point at which a pressure roller the strip to the plate edge push to connect him with this.
    In the field of use of these devices, there is a great need to have a working head of the heater with extremely small dimensions, which is why it is necessary that this is suitable for heat transfer with high power density.
    Thus, the problem underlying the present invention is to provide an edge banding device which allows greater efficiency in fixing the strip to the plate edge than conventional edge banding devices.
    The main object of the present invention is the realization of an edge banding device which offers a solution to the above problem.
    Within the scope of this aim, the object of the present invention is to provide an edge banding device which makes it possible to transfer heat with a higher power density than conventional edge banding devices.
    Another object of the present invention is to provide an edge banding apparatus which is adaptable to the application of edge strips of different heights.
    A still further object of the invention is to provide an edge banding apparatus which has high energy efficiency and minimizes undesirable losses due to dissipation.
    Another aim of the invention
    Edge banding device is to enable a more effective bonding than in the conventional devices.
    This object, as well as these and other objects, which emerge even more clearly from the following description, are achieved with a Kantenanleimvorrichtung according to the appended claim 1.
    The detailed features of a Kantenanleimvorrichtung invention are given in the dependent claims.
    In particular, such an edge banding device according to the invention makes it possible to achieve greater efficiency in fixing the strip to the plate edge by increasing the thermal power density transferred to the adhesive of the edge strip, thanks to heat transfer obtained simultaneously by radiation and convection, than in conventional devices.
    According to a preferred aspect of the invention, it is provided to modulate the output range of the heat output in order to adapt to the height of the edge strip to be applied, in order thus to obtain a greater versatility of the edge banding device according to the invention.
    According to a further advantageous aspect of the present invention, it is possible to locally concentrate the dissipated heat output in the direction of the strip so as to be able to obtain a particularly effective adhesion to the edge regions or other arbitrarily selected regions and to ensure that the heat in the respective Area is discharged evenly.
    According to another preferred aspect of the present invention, the edge banding device provides to heat by means of one and the same heat source both the strip and an adhesive which is to be applied to the edge to be provided with the strip.
    Further features and advantages of the invention will be more clearly illustrated in the following description of a preferred embodiment by no means exclusive of an edge banding device according to the invention with reference to the accompanying drawings. 1 is a schematic perspective view of an edge banding device according to the invention; FIG. 2 is a schematic plan view of a detail of the edgebander of FIG. 1 relative to the heater; FIG. FIG. 3 is a sectional view taken along the plane III-III of FIG. 2 of the detail of FIG. 2; FIG. FIG. 4 is a schematic plan view of a variant of the heating device; FIG. - Fig. 5 is a schematic perspective view of another embodiment of the heater.
    With reference in particular to the said figures, the reference numeral 10 in its entirety denotes an edge banding device for fixing a
    Kantenabschlussstreifens 11 at one edge of a plate.
    According to the invention, the edge banding apparatus 10 has a certain feature which is that it includes a heating device 12 having a side A which in use is contacted by the strip 11 to heat it.
    The heater 12 is configured to heat and configure a surface of the strip 11 to transmit thermal power thereto by simultaneous radiation and forced convection.
    For the sake of clarity only, in the attached figures side A is shown stylized with a dashed segment.
    In detail, the edge banding apparatus 10 advantageously comprises: a feed device 13 for a plate 14 to be provided with an edge strip, guide means 15 for guiding the strip 11 along a feed direction C; a connecting device 16 adapted to press the strip 11 against the edge 14a of the plate 14; a head 17 supporting the heater 12 inserted between the strip 11 and the edge 14a of the plate 14 upstream of the connecting device 16.
    Thanks to the combined effect of radiation and forced convection, by means of a
    Edge banding apparatus 10 according to the present invention can be obtained on the strip transferable thermal power density values, which are far greater than those achieved with conventional devices, so that it is possible compared to the latter, a greater completeness of the head 17 and a closer approach of the head to the joint between strip 11 and edge 14a, so that a more efficient connection between the strip 11 and the plate 14 can be achieved. Preferably, the heater 12 includes a heatable thermal assembly 18 that is configured to emit thermal radiation from the side A to heat in use the surface of the strip 11.
    The thermal assembly 18 advantageously includes a plurality of radiators 19, which are electrically heated and preferably arranged as a battery.
    To extend the life of the radiator 19, these are preferably formed as wire-shaped elements with an outer diameter between 3 mm and 15 mm and include: - a core of metallic material having a diameter of 0.1 mm to 1.5 mm; a cladding surrounding this core of a material selected from a ceramic material, a quartz-containing material, and an inert gas capable of preventing the deposition of metal.
    The radiators 19 advantageously have mutually parallel sections along a working direction B.
    In alternative embodiments, all of which fall within the scope of protection defined by the appended claims, the heating resistors 19 advantageously comprise, instead of the wire-shaped elements or combined with them, infrared-emitting elements, preferably consisting of incandescent lamps and preferably of plasma lamps and / or tungsten lamps.
    To increase the efficiency of the Kantenanleimvorrichtung 10, in particular the following advantageous embodiments are proposed.
    In an advantageous first embodiment of the present invention, the working direction B of the radiators 19 is parallel to the feeding direction C and the edge banding device 10 is configured to selectively activate the radiators 19 to adjust the radiation range of the thermal assembly 18 to the height of the strip 11 to be heated.
    In FIG. 3, dashed lines show strips 11 of different height, for which a selective activation of the correspondingly directed radiator 19 is advantageous.
    More specifically, this first embodiment preferably provides that the radiators 19 are arranged as a battery, with portions that are parallel to each other, coplanar and parallel to the surface of the strip to be heated, as shown for example in FIG.
    In this case, by activating a selection of radiators 19, it is possible to define a radiation area D which can either correspond to a specific part of the height of the strip or to the height of the strip to avoid losses of heat output due to dissipation. which would result from feeding the radiators, which are not facing a portion of the edge strip.
    In particular, according to this first embodiment, the edge banding device 10 thus makes it possible to optimize the thermal output in the case of edge strips of different heights, since in this case it is possible to activate only the emitters which are actually arranged directly facing the edge strip.
    A second advantageous embodiment of the present invention differs from the above-mentioned first embodiment in that the edge banding apparatus 10 preferably includes a movable screen 20 on the side A to partially shield the thermal assembly 18, and thus the radiation range of the thermal assembly 18 of the height of the to adapt to heating strip 11.
    Preferably, in this second embodiment, the radiators 19 are arranged orthogonal to the feed direction.
    Further, the shield 20 advantageously has a reflective surface which faces the radiators to reflect the thermal radiation and reduce its loss by dissipation.
    According to this second embodiment, by moving the screen with respect to the radiators 19, the extent of a radiation area D can be modulated in a manner comparable to that described for the first embodiment.
    The heater 12 preferably includes reflective means 21 to reflect a thermal radiation emitted by the thermal assembly 18 in use such that the reflected radiation from the side A is directed to the strip 11, which in use and guided by the latter Guidance means touched.
    The reflective means 21 advantageously include at least one parabolic profile 22 adapted to concentrate a thermal radiation emitted by the thermal assembly 18 along a predetermined focal direction E to concentrate the thermal radiation onto at least a selected portion of the strip 11.
    In particular, to effect an increase in the adhesion of the strip 11 to the edges, parabolic profiles 22 may be provided which are arranged to concentrate the thermal radiation on the edges.
    Preferably, the edge banding apparatus 10 includes an air or water cooling circuit (not shown in the accompanying figures) thermally connected to the reflective means 21 for dissipating heat therefrom and a heating element (not shown) configured therefor is to engage the edge of the plate to heat the heating element and, via this, in use, the edge of the plate.
    The heater 12 advantageously includes a flow diverter that is shaped so that, in use, an airflow is directed from the side A to the strip 11 after exchanging heat with the thermal assembly 18 upstream thereof.
    Preferably, the edge banding apparatus 10 includes means for generating an airflow coupled to the deflector for directing forced airflow thereon.
    In Fig. 2, said air flow is shown as a non-limiting example with dashed arrows.
    Preferably, this deflector includes the reflective means 21, as these are shaped to direct an air flow to pass over the thermal assembly 18 to be heated by it, and then to the strip 11 from the side A. steer to warm it.
    In particular, the reflecting means 21 preferably include: a wall 21a which is mainly parallel to the feeding direction C; a curved edge 21b adapted to direct an air flow sweeping the wall 21a in a direction substantially divergent from side A to flow against the strip 11.
    In one embodiment of the present invention, which is illustrated in FIG. 1 by way of non-limiting example, the edge banding apparatus 10 includes a reservoir 23 for adhesive and an applicator 24, for example a roller communicating with the reservoir 23, around the adhesive to be applied and disposed with respect to the advancing device 13 so as to engage the edge 14a of a plate 14 which in use is advanced by the advancing device 13.
    According to an advantageous aspect of the present invention, the reservoir 23 is in thermal communication with the heater 12 to heat the adhesive.
    Preferably, the reflective means includes a wall configured to transfer heat by conduction, one side of which faces the thermal assembly 18 and the other side of which is in thermal contact with the reservoir 23 to heat the adhesive.
    According to an advantageous aspect of the present invention, the radiators 19 include or are replaced by halogen lamps and / or plasma lamps and / or generally tungsten lamps.
    In an embodiment not shown in the attached figures, the edge banding apparatus includes an applicator device arranged to apply an adhesive layer on the surface of the strip to be adhered to the workpiece edge.
    This adhesive is advantageously capable of substantially curing once it is applied to the strip but is reactivatable at low temperature, so that it is possible to require a lower specific heating power from the heater.
    Thus, according to this variant, the edge banding device has a preparation station which contains the application device and, downstream of the preparation station, a reactivation station which contains the heating device.
    Since the plastic materials used, such as adhesives and glues, have a different sensitivity to the infrared emission spectrum, in a further embodiment of the edge banding device according to the invention, it is possible to vary the wavelength of the radiation emitted by the heating device, but without leaving the infrared range ,
    This advantageously makes it possible to melt the adhesives more or less deeply, depending on the particular characteristics of the composition.
    For this purpose, the heating device is advantageously equipped with means for emitting warming radiation capable of modulating the emission within the infrared range, so that the wavelength varies depending on the material and / or adhesive to be activated and its layer thickness can be.
    For example, it may be possible to modulate the power supply of these radiator means, or they may comprise radiator elements of different materials which can be selectively energized and each of which is capable of emitting infrared radiation whose wavelength differs from that of the other elements in that, depending on which element (s) is fed, the heating device can emit a radiation of the respectively desired wavelength.
    In other words, the heating device advantageously includes at least one emission source for infrared radiation, which is configured such that the wavelength of the emitted radiation can be modulated.
    Structurally, the edge banding apparatus is advantageously provided with means for modulating the supply of the heating device, which is equipped with a plurality of infrared radiators connected to the modulation means.
    In a first embodiment, the latter are advantageously configured to selectively feed said radiators.
    In this case, the emitters each include emitters, each differing in the frequency of radiation they emit as soon as they are energized.
    In a second, alternative embodiment, the modulation means are advantageously configured to modulate the power supply of the radiators.
    In this case, the latter are configured to emit infrared radiation whose frequency is in
    Depending on the supply power of the radiator itself is variable.
    Of course, any combination of these two embodiments is also possible in which the modulation means are simultaneously configured to modulate the power supply and to selectively feed the radiators.
    In general, the edge banding device preferably includes a programmable controller connected to the modulation means for controlling the same.
    The described invention may admit to numerous variations and variants, all of which fall within the scope of the inventive idea.
    Furthermore, all the details of the invention may be replaced by technically equivalent elements.
    In the practice of the invention, the materials used as well as the respective shapes and sizes can be varied as desired according to the respective requirements and the state of the art.
