Definitions

the invention relates to a method and a device for producing friezes (frames) and slats for slat doors.
friezes and slats are used. each made from different, commercially available wooden boards.
the quality of the wood serves as a criterion for the choice of which boards are processed into friezes or lamellas, in particular the presence of knotholes plays a major role.
Higher quality wooden boards are processed into friezes, the other boards, with more knotholes, into lamellas.
the boards selected for the production of slats are first e.g. using multi-blade circular saws, sawn into strips with a rectangular cross-section.
the strips that meet the quality requirements are then subjected to further processing and surface treatment in order to produce lamellae of the desired cross-sectional shape.
This processing can e.g. in a molding machine, the strips having to be planed, sanded and rounded on their narrow sides in order to be used as slats for slat doors.
planing for example. is carried out by planing shafts with a removal of 0.8 mm, which is particularly important with a thickness of the slats of only a few mm.
the conventional methods require a variety of operations. This not only increases the manufacturing costs, the various clamping and unclamping processes or the repeated feeding also adversely affect the quality of the slats produced, particularly with regard to their dimensional accuracy.
the invention has for its object to provide a method for the production of friezes and slats for louvre doors, with which the wood suitable for friezes or slats can be selected better than in conventional processes. Quality can be made.
the other blanks are preferably further processed to a plurality of lamellae using a method according to claim 2.
the lamellae are produced from a blank in a multiple process by profiling and then cutting or separating the blank; The required depth of cut is shortened by the previous profiling, so that a lower saw blade thickness is sufficient and thus less waste is incurred. If the flanks of the grooves formed during the profiling are already designed in accordance with the desired shape of the narrow side of the lamellae, there is no machining operation required in conventional lamellae production.
Quality is the profiling and cutting of the blank in a single operation without unclamping the blank in a single device, which in addition to a feed device for the blank, a milling or grooving device for profiling the blank in the manner described above and a separating device.
the blank is cut into lamellas only after profiling, and specifically along the profile grooves, the required depth of cut is shortened, preferably by more than 15%, and the lower saw blade thicknesses that are thus possible also reduce less Waste on.
a further material saving can be achieved in that the blank is cut by cuts from both sides into one of the two rows of grooves produced during profiling. This measure allows the required depth of cut per saw blade to be cut in half, so the blade thickness and thus the waste can be reduced further.
the sheet thicknesses used preferably correspond to the width of the grooves.
the device according to the invention for producing wooden lamellae from a blank has a feed device with precise guidance of the blank, a milling or grooving device for forming the longitudinal grooves of the blank in the manner described above and a multi-blade saw bushing or multi-blade circular saw with the width of the grooves as a separating tool Leaf thicknesses.
a profiling head are provided for profiling the blank in order to avoid the otherwise necessary unclamping and turning of the blank, which are identically shaped and each form the longitudinal grooves on one of the two long sides of the blank.
multi-blade circular saws or multi-blade saw bushes arranged offset in the feed direction of the blank are used as cutting tools, each cutting through about half of the required depth of cut, whereby blade thickness and waste can be reduced.
the thickness d, preferably about 52 mm, of the commercially available wooden board 1 shown in FIG. 1 corresponds to the width of the friezes to be produced.
its width h corresponds to a multiple of the thickness h 1 (preferably about 32 mm) of the friezes to be produced, plus the cutting widths.
the board 1 is sawed lengthwise into several blanks 2 which are rectangular in cross section. The Section planes are indicated in FIG. 1 by dashed lines.
the cross-section of the blank 2 given by the width d and the thickness h 1 corresponds to that of a frieze to be produced plus the material removed during a possible subsequent surface treatment; its length 1 should preferably correspond to a multiple of the length of a finished frieze.
the further processing according to the invention of a blank 2 which is not suitable as a frieze to form a plurality of lamellae 3 is shown in FIG. 2.
the thickness h 1 of the blank 2 corresponds approximately to the width of the slats 3 to be produced, its reited B, in order to achieve optimal utilization of the material, a multiple of the thickness d 1 of a lamella 3 plus the blend widths.
the length l 1 of the blank 2 normally the same length as the length 1 of the wooden board, preferably corresponds to the length of a finished lamella 3 or a multiple of this length.
the blank 2 is first profiled by means of a milling or molding machine with at least one suitably shaped milling head on two opposite longitudinal sides perpendicular to the cross-sectional area and to the side surface in such a way that these pairs of opposing, equidistant grooves 4,4 'running parallel to the longitudinal axis of the blank 2 exhibit. This profiling is illustrated in FIG. 2 by dashed lines.
the subsequent separation of the blank 2 into a plurality of lamellae 3 takes place by cuts in the longitudinal direction along the grooves 4, 4 ', the cutting planes in FIG. 2 being indicated by dash-dotted lines 6.
the depth of cut h 2 between opposing grooves 4, 4 ' is smaller than the thickness h 1 of the blank 2 due to the previous profiling of the blank 2.
h 1 32 mm
h 2 with a groove depth of 3 mm is approximately 26 mm and can with appropriately shaped milling heads can be reduced to approximately 20 mm. For this reason, since thinner saw blades can be used, the amount of waste is also reduced.
the saw blade thickness preferably corresponds in each case to the width b of the grooves 4, 4 ', and the cut is carried out so precisely along the grooves 4, 4' that burr formation is avoided. If, in addition, the profile 5 formed between the grooves 4, 4 'or the respective groove flank is reproduced by appropriate selection of the milling heads of the desired shape of the narrow side of the lamellae 3, for example rounded or semicircular in cross section, the is for reworking or smoothing lamellae 3 produced by the cutting process only required grinding. Grinding can be carried out with a removal of approximately 0.2 mm and at a high feed rate, while the slower planing required in conventional processes and which causes a larger removal can be eliminated. If the length l 1 of the blank 2 is a multiple of the length of a finished lamella 3 to be produced, the parts formed in the longitudinal direction by the separating process for producing the lamellae 3 must be cut to the desired lamella length by sawing.
Fig. 3 is an elevation in schematic form Device according to the invention for producing lamellae 3 from a blank 2 is shown.
two milling heads 8 and 9 are shown for profiling the blank 2 on two long sides in the manner described above. If only one milling head 8 or 9 is used, the blank 2 must be rotated by 180 ° after profiling one long side and is then profiled on the other long side.
the profiling of both longitudinal sides is carried out simultaneously by the two milling heads 8 and 9 which process the upper and lower longitudinal sides and which can also be arranged offset in the direction of advance of the blank.
their correct setting relative to one another ensures that the equidistant grooves 4, 4 ', which run parallel to the longitudinal axis of the blank 2, are exactly opposite each other in pairs.
each saw only has to cut through the depth of cut from the respective groove 4, 4 'to the central plane 13, that is to say only about half of the total depth of cut h 2 . Therefore, if two multi-blade saw bushings 11 and 12 are provided, thinner, less waste saw blades can be used.
the blank 2 is in the entire device according to the invention both before and after passing through the milling heads 8, 9 as accurately performed, that is needed for reworking of the lamellae produced, in addition to the possibly necessary sawing to the desired length, only a smoothing of the surface by grinding, regardless of whether one or two Dahlblattsä g ebüchsen 10 regarding. 1 1 , 12 can be used.
the partial section shown in FIG. 4 in the plane IV-IV of FIG. 3 represents an embodiment of the milling heads 8 and 9, which is suitable for forming flat side surfaces of the lamellae 3 with rounded edges.
any other shape of the milling heads 8, 9 which forms the narrow sides of the lamella 3 in the desired manner during the profiling process can also be provided.
