Description

[0001] The invention relates to an arrangement and a method for processing an edge of a furniture panel provided with an edge band using this arrangement. The arrangement comprises a processing unit with a jet nozzle directed toward an edge region of the furniture panel and a feed device for generating a relative movement between the furniture panel and the jet nozzle in the direction of a longitudinal extension of the edge.

[0002] Furniture construction makes a wide variety of use in furniture construction, furniture panels made from wood or a wood-like material such as chipboard, medium or high density fiberboard, or lightweight construction panels. The sides of the panels are usually coated. After the panels have been cut to size, the cut edges are processed in edge processing machines or systems by applying, or in particular gluing, an edge band. Excess edge banding that projects beyond the sides of the furniture panel is usually removed using milling equipment. A milled edge that is rough after milling can be smoothed, trimmed, or rounded off in a subsequent step using a scraper to create a visually and haptically appealing transition between the side and end faces of the furniture panel. Removing the excess and any resulting...subsequent smoothing with at least one scraper is collectively referred to as the formatting process.

[0003] From the publication DE 200 14 953 U1, it is known to apply a liquid to the edge area of ​​the furniture panel to be processed using a jet nozzle before milling off an edge band overhang and / or reworking the edge band overhang with a scraper. This can effectively prevent milling chips, chips removed by the scraper, or adhesive residues from adhering to the surface of the furniture panel.

[0004] The document DE 10 2010 032 845 A1 describes the treatment of an edge area of ​​a furniture panel to be processed using a plasma jet emitted by a plasma nozzle.

[0005] Furniture panels and the edgebands used are available on the market with a wide variety of surface properties. Matte surfaces are increasingly being offered and in demand. The previously described formatting process of processing the edgeband overhangs by milling and surface finishing with a scraper and optionally additional polishing wheels results in a glossy surface in the processed area of ​​the edgeband, particularly in the case of edgebands made of plastic. The different gloss impressions on the surface of the furniture panel or the end face of the edgeband and the processed area of ​​the edgeband disrupt the uniform overall appearance of the furniture panel.

[0006] It is an object of the present invention to provide an arrangement of the type mentioned above and a method with which the disturbing gloss difference in the machined area of ​​the edge of a furniture panel can be eliminated, so that the edge has a uniform surface appearance. The arrangement and method should be capable of being integrated into conventional processing processes for applying an edge band to a furniture panel, and the method should be particularly feasible in a continuous process.

[0007] This object is achieved by an arrangement or method having the features of the respective independent claim. Advantageous embodiments and further developments are the subject of the dependent claims.

[0008] In an arrangement according to the invention of the type mentioned at the outset, the blasting nozzle serves to direct a blasting material jet with particulate blasting material onto the edge area of ​​the furniture panel.

[0009] The invention is based on the finding that the machined area of ​​the edge band of the furniture panel can be effectively mattified using a blasting jet in order to adapt the optical properties of the smooth and shiny surface created in previous processing steps to the rest of the surface of the furniture panel or edge band. Treatment with a blasting jet is also well suited to being carried out as a continuous process, with either the furniture panel running past the blasting nozzle or the blasting nozzle being guided along the furniture panel. A further advantage of the process is that any remaining residues of protective film present in the edge area on the furniture panel and / or the edge band are removed. The otherwise necessary subsequent manual removal of the protective film is no longer necessary.Excess adhesive residues, chips, or dust from previous process steps can also be advantageously removed by the blasting agent jet. This makes the use of the arrangement or method according to the invention advantageous for edge processing where adjusting the optical appearance is not necessary or a priority.

[0010] In a method according to the invention, correspondingly particulate blasting material is blasted through a blasting nozzle onto an edge region of the furniture panel, while the furniture panel is moved relative to the blasting nozzle and / or the blasting nozzle is moved relative to the furniture panel in the direction of a longitudinal extension of the edge.

[0011] According to the invention, compressed air and blasting media are fed together to the blasting nozzle via a single supply line. The combined compressed air and blasting media supply is connected, if necessary via a controllable valve, to a blasting media container pressurized with compressed air. Furthermore, a vibration generator, preferably driven by compressed air, is arranged in or on the blasting media container. This prevents bridging within the stored blasting media.

[0012] In an advantageous embodiment, the blasting material container also serves as a storage container and has an internal volume of several liters. The blasting material container preferably has a conveyor pipe that extends into a lower area of ​​the internal volume of the blasting material container and has an opening there. The combined compressed air and blasting material supply is connected to this conveyor pipe.

[0013] The method according to the invention requires only a very small flow of blasting material (i.e. mass or volume of blasting material per unit of time), but this flow must be highly constant over time. This presents a particular challenge, which can be advantageously met by arranging a mixing tube pressurised with compressed air within the blasting material container, said mixing tube having an opening positioned adjacent to the opening of the conveyor tube. For this purpose, the conveyor tube preferably runs within the mixing tube. More preferably, the openings of the conveyor and mixing tubes are spaced apart from one another in the longitudinal direction of the tubes, so that a mixing space for blasting material and compressed air is formed. The vibration generator works particularly effectively when it acts directly on the conveyor tube and / or the mixing tube in the region of the openings.It is noted that in the context of this application, the term "pipe" is to be understood relatively broadly, such that a rigid hose or similar can also be used as a conveying pipe or mixing pipe.

[0014] The blasting material may contain inorganic particles, in particular sand, corundum, slag, and / or steel particles, or organic particles, such as plastic particles, and in particular organic and biodegradable particles, such as ground nutshells, soda, and / or dried and ground corn. The average particle size is preferably between 50 µm (micrometers) and 1 mm (millimeters).

[0015] The feed device can be, for example, a conveyor belt, conveyor chain, or roller conveyor. Preferably, the feed device can be part of an edge processing machine for applying and finishing the edge band. In this case, the processing unit can advantageously be mounted in or on the edge processing machine and, in particular, can be arranged downstream of a scraper, which is used for finishing the edge band after milling off the excess. The matting process according to the invention can thus be integrated into existing systems and processes without significant additional effort.

[0016] In the aforementioned edgebanding machines, the furniture panel is typically moved past processing tools at a speed of approximately 4 to 60 m / min (meters per minute). A speed of this magnitude is also well suited for the present process, which is why integration into the edgebanding machine is straightforward.

[0017] It has proven advantageous that the blasting nozzle has a nozzle opening with a diameter in the range of 1 to 8 mm, whereby the diameter used depends not only on the size of the area in which matting is to take place, but also on the distance of the blasting nozzle to the surface of the edge band and operating parameters such as the operating pressure of the compressed air used and the blasting material used.

[0018] The blasting nozzle can be directed perpendicularly or inclined relative to a surface of the furniture panel and / or relative to a longitudinal direction of the edge band toward the edge region, wherein angles between the blasting nozzle and the surface of the furniture panel or between the blasting nozzle and the longitudinal direction of the edge band are greater than 0 and less than or equal to 90° and preferably lie in the range of 30° to 60°. With regard to an orientation relative to a longitudinal direction of the edge band, it has proven preferable for the blasting material jet to strike the furniture panel opposite to its direction of movement.

[0019] In a further advantageous embodiment of the arrangement, at least the nozzle opening of the blasting nozzle is surrounded by an extraction hood to extract the blasted material as completely as possible. An opening of the extraction hood facing the furniture panel is preferably provided with a seal, for example in the form of a sealing lip, a sealing curtain, and / or a brush. The extraction hood can effectively prevent contamination of the furniture panel and / or other processing machines. Extraction systems are usually already available on the processing machines used, to which the extraction hood can be connected.

[0020] The invention is explained in more detail below using an exemplary embodiment and figures. The figures show: Fig. 1 is a partially sectioned side view of an arrangement for processing an edge of a furniture panel; Fig. 2, 3 is a front view and a top view of the arrangement according to Fig. 1 ; Fig. 4 is a schematic isometric representation of an extraction hood of an arrangement for processing an edge; and Fig. 5 is a plan view of an embodiment of an arrangement for processing an edge of a furniture panel.

[0021] In the Figures 1-3 A non-inventive arrangement for processing an edge of a furniture panel 1 provided with an edge band 2 is shown in schematic views from different sides. In all figures, the same reference numerals identify the same elements. For reasons of clarity, not all elements are provided with reference numerals in all figures.

[0022] The arrangement shown is used in the manufacturing process of the furniture panel 1, after the edge band 2 has been attached to an end face, also called the narrow side, of the furniture panel 1. The furniture panel 1 can be, for example, a chipboard, a medium-density or high-density fiberboard, or a lightweight panel that has a surface coating on one or both opposite sides. The applied edge band 2 can, for example, be a plastic strip applied to the narrow side of the furniture panel 1 in previous processing steps. This can be done, for example, using adhesive, e.g. a hot melt adhesive, which is previously applied to the narrow side of the furniture panel 1 or the edge band 2. It is also possible to use an edge band 2 that has a functional layer that can be activated by hot air or laser radiation, via which it is attached to the narrow side of the furniture panel 1.

[0023] After removing excess material, e.g., by milling, a radius (as in this case) or, alternatively, a chamfer or other profile geometry is typically formed onto the edgeband using a scraper. If necessary, additional polishing and / or cleaning steps may be performed on the edge area of ​​the furniture panel 1. These steps are collectively referred to as the edgeband formatting process. The formatting process can result in a glossy surface of the edgeband 2 in the processed area.

[0024] In order to mattify the machined area of ​​the edge band 2 and to adapt its gloss level to the remaining surfaces of the furniture panel 1 or the unmachined part of the edge band 2, the arrangement according to the application comprises a processing unit 10 with a blasting nozzle 11 in which a blasting material jet 5 is formed, which is then blasted onto the edge area of ​​the furniture panel 1. For this purpose, the blasting nozzle 11 has a nozzle opening 12, which is positioned at a short distance of a few millimeters to the centimeter range in front of the machined area of ​​the edge band 2. The diameter of the nozzle opening 12 is also in the millimeter range, in particular between one and eight millimeters.

[0025] On the side of the blasting nozzle 11 opposite the nozzle opening 12, a compressed air supply 13 is arranged, via which compressed air 3 is supplied to form the blasting material jet 5. Blasting material 4, which is supplied via a blasting material supply 14, is mixed with the compressed air 3. For this purpose, a constriction can be formed in the compressed air supply 13, behind which a negative pressure is generated according to the Venturi principle, which sucks the blasting material 4 through the blasting material supply 14. Alternatively or additionally, the blasting material 4 can be supplied under pressure from a pressure vessel. According to the invention, the blasting material 4 and the compressed air 3 are supplied together from a container pressurized with compressed air via a single supply to the blasting nozzle 11. An embodiment with this type of blasting material supply is shown in Fig. 5 and is explained in more detail below.

[0026] Various abrasive particles can be used as blasting media 4, for example, sand, corundum, slag, steel, or plastic particles. Biodegradable particles, such as ground nutshells, dried and ground corn, or soda, can also be used. The grain size can be, for example, between 50 µm and 1 mm, whereby the selection of the material and / or the average grain size for the blasting media 4 depends on the material of the edge band 2 and the desired matting of the edge area of ​​the furniture panel 1.

[0027] Other parameters that influence the matting effect are the length of the jet nozzle 11, which can be between 20 and 300 mm, for example, and the pressure of the supplied compressed air 3, which can be between approximately 1.5 and 8 bar. The length of the jet nozzle 11 and the pressure of the supplied compressed air 3, as well as the material selection and grain size, influence the speed of the particles emerging from the nozzle opening 12 and the jet expansion after exiting the nozzle opening.

[0028] Furthermore, it may be provided to add other substances, for example liquids, to the compressed air 3, the blasting material 4 or the blasting material jet 5 in order to modify the effect of the blasting material jet 5.

[0029] The irradiation of the processed area of ​​the edge band 2 with the blasting material jet 5 occurs during a relative movement of the processing unit 10 relative to the furniture panel 1. In the example shown, the processing unit 10 is stationary, and the furniture panel 1 is moved past the processing unit 10 using a feed device 20. The feed device 20 can be a conveyor belt or a roller conveyor.

[0030] The processing unit 10 is advantageously mounted within an edge processing machine that attaches the edge band 2 to the furniture panel 1 and processes it using a protrusion cutter and, if necessary, a scraper. The processing unit 10 is arranged behind the scraper in the running direction of the furniture panel 1. The relative movement occurs at the machine-typical feed rate, which is approximately between 4 and 60 m / min.

[0031] Alternatively, the processing unit 10 can be arranged independently of other processing steps on a separate conveyor belt or roller conveyor, which is located downstream of the previously mentioned edge preparation (gluing, milling off the excess, scraping).

[0032] In a further alternative embodiment, the furniture panel 1 can be held stationary, and the processing unit 10 can be moved along the edge of the furniture panel 1. For this purpose, the processing unit 10 can be moved along an edge, for example, as a processing head of a CNC machine. In such an embodiment, the arrangement is particularly suitable for processing furniture panels with non-straight edges or free-form parts.

[0033] As seen from the side view in Fig. 1As can be seen, the jet nozzle 11 is arranged at an angle α relative to the surface of the furniture panel 1. In the illustrated case, in which the edge of the edge band 2 is symmetrically rounded, the angle α is advantageously 45°. For other geometries of the edge area of ​​the edge band 2 or the furniture panel 1, the angle α can be selected between approximately 0 and 90°. Figures 2 and 3 show that the jet nozzle 11 can also be arranged inclined relative to the longitudinal extension of the edge of the furniture panel 2. In Fig. 3 This inclination is shown as an angle β relative to the alignment of the edge or the longitudinal direction of the edge band 2 of the furniture panel 1. Furthermore, the Figure 3a running direction 21 of the furniture panel 1 during its movement relative to the processing unit 10. It has proven advantageous to select the angle β smaller than 90° so that the blasting material jet 5 strikes the edge band 2 opposite to the running direction 21 of the furniture panel 1.

[0034] In order to prevent contamination of the furniture panel 1 as well as all other processing machines or the feed device 20, the opening of the jet nozzle 11 is arranged within a suction hood 15. This is connected via a suction connection 16 to an extraction system 6, which is integrated in the Figures 1 and 3symbolized by arrows that represent the direction of extraction. The extraction system 6 can be a central extraction system, which is also used to collect sawdust and / or milling chips, etc. from the processing machines. Alternatively, a separate extraction system 6 can be provided, which offers the possibility of collecting the blasting material 4 through appropriate filters and, if necessary, reusing it after a recycling process. If joint extraction takes place with sawdust or milling chips, the use of organic material as blasting material 4 is advantageous, since this can be further processed together with the sawdust or milling chips without any problems, for example, it can be formed into fuel pellets.

[0035] The extraction hood 15 is positioned as close as possible to the furniture panel 1 and also to the edge band 2 so that as little blasting material 4 as possible leaves the area of ​​the extraction hood 15 or, in other words, as much of the supplied blasting material 4 as possible is absorbed by the extraction system 6. For this purpose, the air flow absorbed by the extraction system 6 is selected such that it exceeds the supplied air flow of the compressed air 3.

[0036] Fig. 4 shows the extraction hood 15 separate from the processing unit 10 in a schematic isometric view. It is essentially box-shaped and can be made of sheet metal, for example. It has an extraction opening 17 into which the extraction connection 16 is inserted. A nozzle recess 18 is also provided, through which the blasting nozzle 11 is guided into the edge area.

[0037] Edges of the opening of the extraction hood 15 pointing towards the furniture panel 1 are in the Fig. 4by a greater knitting thickness. A seal 19 can preferably be formed along one or more of these edges in order to keep the gap remaining towards the furniture panel 1 as small as possible and to prevent the blasting material 4 from escaping. The seal 19 can be formed by a sealing lip, e.g. made of rubber or silicone, or can also be designed as a type of felt curtain or as a brush with soft bristles that extend up to the furniture panel 1 without scratching or otherwise damaging its surface.

[0038] In addition to the primary purpose of the processing unit 10, which is to mat the edge area of ​​the furniture panel 1, the blasting jet 5 also removes any remaining protective film residues present in the edge area of ​​the furniture panel 1 and / or the edge band 2. The otherwise necessary subsequent manual removal of the protective film is eliminated. Excess adhesive residues, chips, or dust from previous process steps are also advantageously removed by the blasting jet, particularly in conjunction with the extraction system 6.

[0039] In Figure 5 is a plan view of an embodiment of an arrangement according to the invention for processing an edge of a furniture panel 1 provided with an edge band 2 in a manner comparable to that in Figure 3 shown.

[0040] The arrangement again comprises a processing unit 10 with a blasting nozzle 11, which generates a blasting material jet 5 with particulate blasting material 4, wherein the blasting nozzle 11 is directed at an edge region of the furniture panel 1. This edge region is moved relative to the blasting nozzle 11 by a feed device 20. A nozzle opening of the blasting nozzle 11 and a surrounding area are arranged under an extraction hood 15 in order to remove as much of the blasting material 4 as possible via an extraction system 6. The basic structure of this part of the arrangement thus essentially corresponds to that of the first example, to which explicit reference is hereby made.

[0041] In contrast to the first example, in this case, the blasting material 4 is supplied to the blasting nozzle 11 already mixed with compressed air 3. Accordingly, a joint compressed air and blasting material supply 1314 leads to the blasting nozzle 11.

[0042] The mixing of compressed air 3 and blasting material 4 takes place in a blasting material preparation 30, which can be arranged remotely from the processing unit 10.

[0043] The blasting material preparation system 30 comprises a blasting material container 31, which is hermetically sealed with a lid 32 and is designed as a pressure vessel. A reserve quantity of blasting material 4 is filled into the blasting material container 31. The volume of the blasting material container 31 is preferably in the range of a few liters, which covers the demand for blasting material 4 for a working period of one or more factory shifts.

[0044] A compressed air supply 13 leads into the blasting material container 31, via which compressed air 3 can be fed into the blasting material container 31 at an overpressure in the range of, for example, a few bar. Figure 5Not shown are valves and / or pressure reducers or pressure adjusters arranged upstream of the blasting material container 31 in the compressed air supply 13, via which the compressed air supply 13 can be shut off and the pressure in the blasting material container 31 can be adjusted.

[0045] The mixture of compressed air 3 and blasting material 4 is taken from the blasting material container 31 via a conveyor pipe 13, which leads to the blasting nozzle 11. Also in the Figure 5 Not shown are preferably controllable valves arranged in the connection between the conveyor pipe 33 and the jet nozzle 11, with which a jet of blasting material emitted from the jet nozzle 11 can be turned on or off.

[0046] The described arrangement and the method described in this application are used to mat a narrow (in the range of millimeters) area on the edge band 2 of the furniture panel 1. Even at high feed speeds of over several tens of meters per minute, this requires only a very low feed rate in the blasting material jet 5, which is, for example, in the range of approximately 1 to 100 grams per minute and in particular in the range of approximately 5 to 25 grams per minute. Due to this low feed rate, the requirements for the blasting nozzle 11, but also for the blasting material preparation 30 and the supply of the blasting material to the blasting nozzle 11, differ fundamentally from most other applications in which blasting material is used abrasively. The very small amount of blasting material per unit of time is required in this case with a very high temporal consistency, since otherwise inhomogeneities in the matting occur, which are immediately noticeable to the eye.The blasting material preparation 30 described below is particularly suitable for delivering the small amount of blasting material per unit of time with a very high degree of consistency.

[0047] The conveyor pipe 33 extends into the lower region of the blasting material container 31. In the context of this application, the term "pipe" is to be understood relatively broadly, such that a rigid hose, e.g., a PE (polyethylene) hose, can also be used as the conveyor pipe 33. The conveyor pipe 33 runs within the blasting material container 31 inside a mixing pipe 34, whose inner diameter is larger than the outer diameter of the conveyor pipe 33. The mixing pipe 34 also extends further downward into the conveyor container 31 than the conveyor pipe 33. In the upper region of the mixing pipe 34, which is also located above the supply of blasting material 4, the mixing pipe 34 is provided with a compressed air inlet 35, through which a portion of the compressed air 3 supplied via the compressed air supply 13 can flow into the mixing pipe 34. At the lower end of the mixing tube 34, a blasting material inlet 36 is provided, for example in the form of a sieve or filter.

[0048] This creates a cavity between the lower end of the conveyor pipe 33 and the lower end of the mixing pipe 34, i.e., the blasting material inlet 36, which is referred to below as the mixing chamber 37. During operation of the arrangement, i.e., with the valve to the blasting nozzle 11 open, compressed air 3 enters the mixing chamber 37 from above through the remaining cross-section between the outside of the conveyor pipe 33 and the inside of the mixing pipe 34, and blasting material 4 enters the mixing chamber 37 from below through the blasting material inlet 36. The compressed air 3 flowing from the mixing chamber 37 into the conveyor pipe 33 entrains particles of the blasting material 4 into the conveyor pipe 33 and thus conveys them to the blasting nozzle 11.

[0049] A particularly constant mixing ratio between compressed air 3 and blasting material 4 is further achieved by coupling the mixing tube 34 to a vibration generator 38, which causes the mixing tube 34 to vibrate, particularly at its lower, free end. These vibrations prevent the formation of particle bridges within the supply of blasting material 4, thus ensuring that the blasting material 4 always slides downwards into the area of ​​the blasting material inlet 36. Furthermore, they lead to a constant flow of blasting material 4 through the blasting material inlet 36, in the form of a cloud of particles of the blasting material 4 forming in the mixing chamber 37, which are then moved along by the compressed air 3.

[0050] The vibration generator 38 can be driven by compressed air or electrically. For safety reasons, particularly with regard to explosion protection, compressed air operation may be advantageous over an electric drive. The vibration generator 38 can generate vibrations, for example, using an imbalance, e.g., by comprising a compressed air-driven turbine that has one or more imbalance weights on its axis.

[0051] The flow rate of blasting material 4 per unit of time as well as a mixing ratio between compressed air 3 and blasting material 4 can be influenced and thus controlled via the level of overpressure of compressed air 3 in the blasting material container 31 as well as the amplitude and / or frequency of the vibrations of the vibration generator 38.
