Definitions

• the invention relates to a method for edge processing in the passage of a coated with an edge band plate, preferably a furniture plate according to the preamble of claim 1 and an apparatus for performing the method.
• edge bands made of polishable plastic, such as acrylic or the like, are increasingly being used, which can be adhesively bonded at least on one side by thermal treatment, the heating taking place for example by means of laser or plasma jets.
• the edge band is designed so that some supernatant remains on the top and / or bottom side after sticking, which is removed in a subsequent step.
• suitable cutting tools such as milling cutters, scrapers or the like are used.
• edgeband undergoes a so-to-speak surface damage due to a roughness that is greater than that of the unprocessed surface, with the result that this surface appears dull against the unworked, high-gloss surface in the sense of matt.
• this represents a recognizable defect that sets the visual value of the entire furniture panel down.
• the use of a polishing tool is proposed in DE 20 2005 002 637 U1, to which a viscous or pasty polishing agent is applied.
• the object of the invention is to further develop a method and a device of the generic type such that an optimization of the operating sequence, in particular with regard to machining of the edge band, is possible with a low constructional and manufacturing outlay.
• the automatic loading of the polishing tool for example a polishing belt, a rotating polishing brush or disk, with e.g. Hard wax provides, contamination of the work area is excluded.
• the polishing compound is applied intermittently to the polishing tool.
• the holding device has a corresponding adjusting device with which, moreover, the polishing compound, for example in block form, bears on the polishing tool with such a pressure that a removal onto the polishing tool is ensured.
• a high-gloss surface is achieved by the polishing, especially by means of hard wax, which, as described, previously appeared dull by the machining.
• the polishing especially by means of hard wax, which, as described, previously appeared dull by the machining.
• this free surface can also be polished if necessary, for which purpose a further holding device is provided which is in correspondence with a polishing tool positioned therefor.
• edge bands used which are processed according to the invention, consist of acrylic glass (PMMA) of a thermoplastic plastic, for example polyethylene terephthalate (PET) or of polycarbonate.
• PMMA acrylic glass
• PET polyethylene terephthalate
• PCC polycarbonate
• a brush attacks preferably a lamella brush, consisting of alternating cloth and sisal slats, the sisal slats in particular for machining a radius produced by the machining, which represents a smooth transition from the plate surface to the broad side of the edge band.
• the flap brush rotates at a number of revolutions of 1400 min "1 and, like the subsequent polishing brush same direction as the direction of passage of the plate. Furthermore, the invention provides in front of the engagement of the flap brush to apply a cleaning agent, which is done in known manner by means of a spray nozzle.
• a cloth brush As a polishing brush, which is acted upon by the dimensionally stable polishing composition, a cloth brush has been found to be particularly advantageous, also in the form of a lamella brush, which is preferably driven with a number of revolutions of 2000 min "1 , while downstream of a further brush is installed, the so-called Tuchläpper or is designed as a buffing wheel and with a rotation speed of 1400 min "1 is driven, all rotating tools are moved rectified with the passage of the plate.
• a cleaning agent is also sprayed on between the polishing tool carrying the polishing compound and the cloth flapper, resulting in an optimum surface finish of the machined edge.
• FIG. 1 shows a device for carrying out the method in a schematic side view
• Figure 2 is a partial section of another embodiment of a
• FIG. 1 shows a device for edge processing of a coated or to be coated plate 1 1, preferably a furniture plate, shown having an upper run 1 and a lower run 2, between which the plate 1 1 is progressively movable in the passage, according to the direction, which is indicated by an arrow visible on the right in the illustration.
• a pressure roller 5 Downstream of the spray heads 3 are milling cutters 4, with which the corresponding, initially uncoated edge of the plate can be machined.
• a pressure roller 5 by means of which a previously heated edge band is pressed against the edge of the plate, wherein a connection of the edge band to the plate is preferably carried out by laser or plasma jets, with which the at least one side adhesive edge band until the adhesive activation is heated.
• the pressure roller 5 is associated with a spray device 6, with which a lubricant on the edge regions of the plate 1 1 and / or on the pressure roller 5 can be sprayed.
• Chop saws 9 are used for the following further processing of the plate 1 1 as well as edgers 10, with which both sides of the plate 1 1 protruding edge regions of the edge band are removed.
• an antistatic coolant is applied by means of the edgers 10 upstream sprayers 8.
• polishing discs 1 2 After the removal of the supernatants of the edge band polishing of the machined edges of the edgeband edged by rotating polishing discs 1 2, to which a dimensionally stable polishing mass 1 3, preferably a hard wax is applied.
• a polishing compound 13 receiving holding device 7 is provided, with which the polishing mass 13 can be pressed against the polishing pad 12.
• the upper run 1 and the lower run 2 are each assigned a holding device 7.
• FIG. 2 shows in an enlarged view in a partial section of the device the so-called polishing area.
• lamella brushes 14 are arranged, which are used after an application of applied by means of spray nozzles 16 cleaning agent, wherein the lamellae of the lamellar brushes 14 alternately made of cloth and sisal.
• Downstream of the polishing pads 12 are further spray nozzles 16 for the application of cleaning agents, which are followed by the use of rotating, so-called Tuchläppern 15 in which the slats consist exclusively of cloth.
• the direction of rotation of all polishing tools corresponds to the direction of passage of the plate 11.
