Definitions
- the present invention relates to a method for sawing at least one plate, in particular a plate stack, with a plate dividing plant, wherein the plate in a first process section of a, preferably first, sawing the Plattenaufteilstrom by means of a first cut or first cuts along a, in particular linear, War4.000line of War4.000es or more, in particular linear and / or mutually parallel,
- the first cut line (s) are arranged obliquely or orthogonal to the second cut line or the second cut lines.
- the division of a plate or even a plate stack by means of a panel splitter is a strictly sequential process.
- plate strips are produced from the plate.
- so-called trimming cuts can also be carried out at the edge of the original plate before or during the first process section.
- these plate strips are then broken down into partial plates. Also in this second process section, it is possible to make trimming cuts at the edge of the original plate.
- At the end of the first part of the process are completely separate plate strips before, at the end of the second part of the process, these are sawn into completely separate sub-plates.
- a plate dividing system is known with which a generic method for sawing at least one plate can be performed.
- the above-mentioned problem with the third cuts is already in the embodiment gem. Fig. 4 shown in this font.
- the solution of the third-cut problem shown in AT 361 700 requires a very complex and thus cost-intensive construction of the panel splitter, which pays off only with very large numbers of plates to be sawn.
- the object of the invention is therefore to further develop a generic method in such a way that it has a panel-dividing system of comparatively simple construction on the one hand feasible and on the other hand but still allows a high production performance when splitting.
- this is achieved by subsequently transporting at least one of the partial plates back from a return transport device of the plate dividing installation to the or one of the sawing devices in a third method section and again sawing it by means of at least one third section.
- a basic idea of the invention is thus, when dividing the plate or the stack of plates, to process the first and second process sections without considering the third cuts, as is known per se, by first sawing out the plate strips from the raw plate or the raw format by means of the first cuts and then the division into partial plates by means of or the second cuts takes place. Whether only one first or second or several first or second cuts are necessary depends on the pattern to be realized. Both in or before the first stage of the method and in or before the second stage of the method, the per se known trimming cuts can be carried out at the edge of the original plate, if necessary. Gem.
- a third method section is now provided. This can be carried out or started subsequently or during the second process section.
- this third process section it is provided to transport at least one of the partial plates or also a plurality of partial plates from the rear transport device of the plate dividing systems back to the or one of the sawing devices in order then to carry out at least a third cut by means of the sawing device so as to saw the partial plate once again and produce the desired final format.
- a basic idea of the invention is therefore that the one or the sawing device used for the first and / or second cuts is also used for the third cuts, by those sub-plates where third cuts are necessary, by machine by means of return transport again this or one of the sawing devices supplies.
- the process can be carried out on a wide variety of panel dividing systems.
- a panel splitter for performing the method have two different sawing means in the form of the first sawing device for the Clearroughe and the second sawing device for the second cuts.
- the third cuts can then be carried out both by the first sawing device and by the second sawing device if the return transport device is designed accordingly.
- methods according to the invention can also be carried out on panel dividing installations which have only a single sawing device. This is possible if, by means of a corresponding return transport device after the first process section, the partial plates for the second process section are optionally returned to the sawing device following a rotation in order then to carry out the second cuts. Accordingly, then gem. the invention by means of the return transport means the sub-plates returned, and then again perform the third cuts with the same sawing. This, of course, only on the part plates, where third cuts must be performed.
- Preferred embodiments of the invention provide that the first cut or cuts are sawn with a first sawing device of the plate-splitting installation along a cutting line of the first sawing device and that the second or the second cuts are sawn with a second sawing device of the panel-forming installation along a cutting line of the second sawing device, the cutting lines the sawing means are arranged obliquely or orthogonal to each other.
- the cutting lines the sawing means are arranged obliquely or orthogonal to each other.
- the cut lines do not necessarily have to be arranged orthogonally, it may just as well be that they are arranged obliquely to one another.
- the term oblique denotes all those angles which are not orthogonal and not parallel. But it is equally possible that the one or more first cuts are sawn with a first sawing the Plattenaufteilstrom along a cutting line of the first sawing and that the second or the second cuts are sawed with a second sawing the Plattenaufteilstrom along a cutting line of the second shege issued, said Cut lines of the sawing arranged parallel to each other are.
- a rotating device for rotating the plate strips following the first process section.
- a plate usually has a base and a top surface and side or end faces.
- the base or top surfaces usually have a much larger area than the front or side surfaces.
- plate plane is understood to mean a plane which lies parallel to the base and / or top surface of a plate or partial plate, preferably runs through the base or cover surface.
- third cuts do not generally have to be made on all partial plates, usually only individual partial plates, which require a further cut.
- the sub-panels, which need not be further sawed by third cuts are already supplied by the further transport device for further processing, while the required third cuts are performed on the first subset of the sub-panels.
- the partial plate is sawn at most by means of a third section. But this does not have to be mandatory be so, it is also conceivable that more than a third section must be performed on a partial plate.
- the sub-plate has to be sawn further only by means of a third cut, it can be provided that at least one of the parts sawed from the sub-plate is removed from a removal device after the third cut without having previously been fed to another of the sawing devices.
- This is expediently provided, in particular, when the partial plate is fed for carrying out the third cut of a first sawing device, which in the normal transport direction is followed by a second sawing device.
- the removal devices can then ensure that the parts of the partial plate produced in the course of the third cut are removed from the normal material flow before reaching the second sawing device.
- Preferred embodiments of the invention further provide that the third cut or the third cuts are sawn along one or more, preferably linear, third cut lines, the third cut lines, as seen with respect to the plate, being parallel to the first cut line (s) or parallel to or the second cut line (s) is (are) arranged.
- Fig. 1 is a plan view of a top surface of a plate to be sawn shown. There are in the form of a cutting plan the first cutting lines 4, second cutting lines 7 and
- Third cut lines 14 of the total to be performed on this plate 1 first, second and third cuts as they, as seen with respect to the plate 1, lie. If all these cuts are made in the correct sequence, the plate 1 is divided into the sub-plates 8 and, if necessary, the sub-plates 8 are disassembled into their parts 13. From the order, gem.
- the invention first carried out the first cuts along the first cut lines 4 in the first process section. In this case, before or in the first process section, as far as necessary, first cuts can also be made as trimming cuts along the marginal first cut lines 4, in order to separate the edge strips 18, which are then generally waste.
- the plate strips 5 produced by means of the first cuts are then sawn into the partial plates 8 in the second method section by means of the second cuts along the second cut lines 7. In this case, the first and the last second cut also the trimming and thus the separation of edge strips 18 are used.
- the Dom.1 serve on the outer Siegismelinien 4 as I said the trimming. This can also be omitted in provided with appropriately clean edges running plates 1.
- the plate 1 is sawn into the two plate strips 5. All this happens in the first part of the procedure.
- the in Fig.1 viewed upper plate strips sawed by means of the second cuts 7 in four sub-plates 8. The same applies to the lower plate strip, but these partial plates 8 have a different format.
- the second cuts are made along the second cut lines 7 in the second method section.
- the third method section is then in the embodiment according to Fig. 1 only a single third section on the sub-plate 8 top left perform. This takes place along the third section line 14 and generates from the partial plate 8, the two parts thirteenth
- Fig. 2 a splitting scheme is shown, in which the plate 1 is first sawed by means of first cuts in three plate strips 5. Subsequently, the division takes place by means of the second cuts in the sub-panels 8, of which then a total of four sub-panels 8, each with a third section along the marked third cutting lines 14 must be sawn.
- Fig. 3 shows a third exemplary allocation scheme, in which from all three plate strips 5 sub-panels 8 with third cuts along the respective third cutting lines 14 must be further sawn.
- Fig. 4 is a schematic plan view of a first panel divider 2, with the method of the invention can be carried out and z. B. in the Fig. 1 to 3 illustrated sectional plans are feasible.
- the plates to be sawn are first fed to the panel dividing plant 2 by means of a plate feeder 19 known per se.
- a per se known feed device 20 then accesses with its known grippers 29 a to be sawn plate 1 or a corresponding plate stack and moves it in the transport direction 22 to the first sawing device 3, with the following after a corresponding orientation to the stops 21 Siegismee along the first cut lines 4 are performed. This happens in the first part of the procedure.
- the plate strips 5 produced thereby are transported by means of the transport device 23 in front of the second sawing device 6.
- both the first sawing device 3 and the second sawing device 6 are under-counter circular saws, which can each be moved along linear cutting lines 15 and 16 in order to carry out the corresponding cuts. Again, this is known and need not be explained again. Of course, other sawing equipment can be used. It is also not necessary that the cutting lines 15 and 16 are necessarily performed linearly. The orthogonal arrangement of the cutting lines 15 and 16 relative to each other is not absolutely necessary.
- the selected or discarded partial plates 8 are again fed to the second sawing device 6 in order to carry out the third cuts along the third cutting line 14 there.
- the other partial plates 8, which do not require any third cuts, can meanwhile be supplied or transported away by the further transport device 12 for further processing.
- the separation of the final formats produced by sawing also preferably takes place on the further transport device 12.
- Fig. 5 schematically shows a plate 1 in a side view of an end face.
- the plate plane 11, which runs parallel to the upper or through the upper top surface of the plate 1, is shown by dashed lines. Also visible is the axis of rotation 25, which is normal on the plate plane 11, around which the rotator 10, the sub-plate 8 rotates before the third cut is performed.
- the axis of rotation is shown in the middle, but the central arrangement of the axis of rotation is not absolutely necessary.
- FIG. 6 now an alternative panel-2 is shown, with which an alternative variant of the method according to the invention can be performed.
- This panel divider 2 corresponds in many details of the panel divider acc. Fig. 4 so that only the differences are discussed here. These are essentially in that the rotary device 10 has been dispensed with. Instead of the rotation, the separated partial plates 8 are now not supplied to the second sawing device 6 but to the first sawing device 3 in order to carry out the third cuts. This eliminates the need for rotation of the sub-plate 8 before performing the third cuts.
- a removal device 17 is also provided following the first sawing device 3, with which the parts 13 taken and following the arrows, can be moved back into the area behind the second sawing device 6, to then be transported by the further transport device 12.
- the rest of the procedure in the implementation of the method according to the invention corresponds to the above. Fig. 4 described and will therefore not be explained again.
- Alternative to the variant gem. Fig. 6 Of course, the separation of the parts 13 behind the first sawing device can be dispensed with. Then these parts 13 are fed over the cutting line 16 of the second sawing device 6 away the further transport device 12.
- the width of the transport devices 9, 12 and 23 is of course shown here only schematically and must be adapted to the respective requirements in order to be able to transport correspondingly large formats of plates 1, plate strips 5 and part plates 8 and their parts 13.
- a further panel dividing plant 2 is shown with which the method according to the invention can be carried out. Again, only the differences to the previously described embodiments will be discussed. In contrast to these gem.
- the third cuts are carried out both by the first sawing device 3 and by the second sawing device 6.
- Fig. 8 shows in a further embodiment of a panel splitter 2, that for performing the method according to the invention, the cutting lines 15 and 16 of the first and second sawing 3, 6 need not necessarily be arranged obliquely or orthogonal to each other.
- the plate strips 5, which are sawn in the first method section by means of the first sawing device 3, are rotated by a rotary device 10 before being fed to the second sawing device 6 for carrying out the second method section. Subsequent to the execution of the second cuts by means of the second sawing device 6, those sub-plates 8 are again taken from the removal device 17 arranged thereon, on which third cuts must be made.
- the sawing devices 3 or 6 From which of the sawing devices 3 or 6 the third cuts are performed, it can also be tuned to which of the two sawing devices 3, 6 is less busy in the implementation of the first and second cuts, so that the implementation of the third cuts the rapid implementation of the first and second process sections not or only slightly delayed as possible.
- the various exemplary embodiments show that the method according to the invention can be carried out in a wide variety of embodiments and on a wide variety of panel dividing installations 2. The variants shown are of course only examples. It should also be pointed out that the panel dividing systems 2 can be composed entirely of known devices and components. Thus, in the prior art various transport devices are known, which can be used in each case at said locations. The same applies to means, such as the stops 21 for aligning the plates. Feed devices 20 and 24 are in various embodiments in the prior art in use. The same applies to the sawing devices 3 and 6 and also to the rotary device 10 and to the removal device 17.

Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Zersägen zumindest einer Platte, insbesondere eines Plattenstapels, mit einer Plattenaufteilanlage, wobei die Platte in einem ersten Verfahrensabschnitt von einer, vorzugsweise ersten, Sägeeinrichtung der Plattenaufteilanlage mittels eines Erstschnittes oder mehrerer Erstschnitte entlang einer, insbesondere linearen, Erstschnittlinie des Erstschnittes oder mehrerer, insbesondere linearer und/oder zueinander paralleler, Erstschnittlinien der Erstschnitte in voneinander vollständig getrennte Plattenstreifen zersägt wird und die Plattenstreifen anschließend in einem zweiten Verfahrensabschnitt von einer, vorzugsweise zweiten, Sägeeinrichtung der Plattenaufteilanlage mittels eines Zweitschnittes oder mehrerer Zweitschnitte entlang einer, insbesondere linearen, Zweitschnittlinie des Zweitschnittes oder mehrerer, insbesondere linearer und/oder zueinander paralleler, Zweitschnittlinien der Zweitschnitte in voneinander vollständig getrennte Teilplatten zersägt werden, wobei, bezüglich der Platte gesehen, die Erstschnittlinie(n) schräg oder orthogonal zu der Zweitschnittlinie oder den Zweitschnittlinien angeordnet wird (werden).The present invention relates to a method for sawing at least one plate, in particular a plate stack, with a plate dividing plant, wherein the plate in a first process section of a, preferably first, sawing the Plattenaufteilanlage by means of a first cut or first cuts along a, in particular linear, Erstschnittlinie of Erstschnittes or more, in particular linear and / or mutually parallel, Erstschnittlinien the first cuts in mutually completely separate plate strips is sawn and then the plate strips in a second process section of a, preferably second, sawing the Plattenaufteilanlage by means of a second cut or a plurality of second cuts along a, in particular linear , Second section line of the second section or several, in particular linear and / or mutually parallel, second section lines of the second sections in each other completely get In this case, the first cut line (s) are arranged obliquely or orthogonal to the second cut line or the second cut lines.
Die Aufteilung einer Platte oder auch eines Plattenstapels mittels einer Plattenaufteilanlage ist ein streng sequenzieller Prozess. In einem ersten Aufteilzyklus bzw. im ersten Verfahrensabschnitt werden aus der Platte Plattenstreifen erzeugt. Dabei können vor oder während dem ersten Verfahrensabschnitt auch sogenannte Besäumungsschnitte am Rand der ursprünglichen Platte durchgeführt werden. In einem weiteren Aufteilzyklus bzw. im zweiten Verfahrensabschnitt werden dann diese Plattenstreifen in Teilplatten zerlegt. Auch in diesem zweiten Verfahrensabschnitt ist es möglich, am Rand der ursprünglichen Platte Besäumschnitte vorzunehmen. Am Ende des ersten Verfahrensabschnittes liegen vollständig voneinander getrennte Plattenstreifen vor, am Ende des zweiten Verfahrensabschnittes sind diese in völlig voneinander getrennte Teilplatten zersägt. Das beim Stand der Technik an sich bekannte Verfahren funktioniert problemlos, solange die im Resultat zu zerschneidenden Teilplatten in zumindest einer Kantenlänge mit einer Breite der im ersten Verfahrensabschnitt zuzusägenden Plattenstreifen übereinstimmen. Problematisch wird es, wenn die Teilplatten, die aus einem Plattenstreifen herausgesägt werden sollen, nicht zumindest in einer Kantenlänge übereinstimmen. Beim Stand der Technik werden in diesem Fall sogenannte Drittschnitte durchgeführt, um aus einem Zwischenformat das letztendlich gewünschte Endformat der Teilplatte herauszusägen. Diese Drittschnitte haben das Problem, dass die Zwischenformate im Anschluss an den zweiten Verfahrensabschnitt noch einmal in die Plattenaufteilsäge eingelegt werden müssen, um den Drittschnitt zur Herstellung der Teilplatte mit gewünschten Dimensionen durchzuführen. Dies ist in Handarbeit sowohl zeit- als auch arbeitsaufwändig. Aus der AT 361 700 ist eine Plattenaufteilanlage bekannt, mit der ein gattungsgemäßes Verfahren zum Zersägen zumindest einer Platte durchgeführt werden kann. Auch die oben genannte Problematik mit den Drittschnitten ist bereits in dem Ausführungsbeispiel gem.
Aus der
Aufgabe der Erfindung ist es daher, ein gattungsgemäßes Verfahren derart weiter zu entwickeln, dass es mit einer einerseits vergleichsweise einfach aufgebauten Plattenaufteilanlage durchführbar ist und andererseits aber trotzdem eine hohe Produktionsleistung beim Aufteilen erlaubt.The object of the invention is therefore to further develop a generic method in such a way that it has a panel-dividing system of comparatively simple construction on the one hand feasible and on the other hand but still allows a high production performance when splitting.
Erfindungsgemäß wird dies erreicht, indem in einem dritten Verfahrensabschnitt anschließend oder während des zweiten Verfahrensabschnitts zumindest eine der Teilplatten von einer Rücktransporteinrichtung der Plattenaufteilanlage zu der oder einer der Sägeeinrichtungen zurück transportiert wird und von dieser Sägeeinrichtung mittels zumindest eines Drittschnittes noch einmal zersägt wird.According to the invention, this is achieved by subsequently transporting at least one of the partial plates back from a return transport device of the plate dividing installation to the or one of the sawing devices in a third method section and again sawing it by means of at least one third section.
Eine Grundidee der Erfindung ist es somit, beim Aufteilen der Platte oder des Plattenstapels den ersten und zweiten Verfahrensabschnitt ohne Berücksichtigung der Drittschnitte, wie an sich bekannt, abzuarbeiten, indem aus der Rohplatte bzw. dem Rohformat zunächst mittels der Erstschnitte die Plattenstreifen herausgesägt werden und anschließend die Aufteilung in Teilplatten mittels des oder der Zweitschnitte erfolgt. Ob jeweils nur ein Erst- oder Zweit- oder mehrere Erst- oder Zweitschnitte notwendig sind, hängt jeweils vom zu realisierenden Schnittmuster ab. Sowohl im oder vor dem ersten Verfahrensabschnitt als auch in oder vor dem zweiten Verfahrensabschnitt können die an sich bekannten Besäumschnitte am Rand der ursprünglichen Platte durchgeführt werden, falls diese notwendig sind. Gem. der Erfindung ist nun ein dritter Verfahrensabschnitt vorgesehen. Dieser kann anschließend oder während des zweiten Verfahrensabschnittes durchgeführt bzw. begonnen werden. In diesem dritten Verfahrensabschnitt ist vorgesehen, zumindest eine der Teilplatten oder auch mehrere Teilplatten von der Rücktransporteinrichtung der Plattenaufteilanlagen zu der oder einer der Sägeeinrichtungen zurück zu transportieren, um dann mittels der Sägeeinrichtung zumindest einen Drittschnitt durchzuführen, um so die Teil-platte noch einmal zu zersägen und das gewünschte Endformat herzustellen. Ein Grundgedanke der Erfindung ist es somit, dass man die oder eine der für die Erst- und/oder Zweitschnitte verwendete Sägeeinrichtung auch für die Drittschnitte verwendet, indem man diejenigen Teilplatten, an denen Drittschnitte notwendig sind, maschinell mittels Rücktransporteinrichtung wieder dieser oder einer der Sägeeinrichtungen zuführt. Das Verfahren kann auf unterschiedlichsten Plattenaufteilanlagen durchgeführt werden. So kann eine Plattenaufteilanlage zur Durchführung des Verfahrens zwei voneinander verschiedene Sägeeinrichtungen in Form der ersten Sägeeinrichtung für die Erstschnitte und der zweiten Sägeeinrichtung für die Zweitschnitte aufweisen. Die Drittschnitte können dann sowohl von der ersten Sägeeinrichtung als auch von der zweiten Sägeeinrichtung durchgeführt werden, wenn die Rücktransporteinrichtung entsprechend ausgebildet ist. Erfindungsgemäße Verfahren können aber auch auf Plattenaufteilanlagen durchgeführt werden, welche nur eine einzige Sägeeinrichtung aufweisen. Dies ist möglich, wenn mittels einer entsprechenden Rücktransporteinrichtung nach dem ersten Verfahrensabschnitt die Teilplatten für den zweiten Verfahrensabschnitt gegebenenfalls im Anschluss an eine Drehung wieder der Sägeeinrichtung zugeführt werden, um dann die Zweitschnitte durchzuführen. Entsprechend werden dann auch gem. der Erfindung mittels der Rücktransporteinrichtung die Teilplatten zurückgeführt, um dann mit derselben Sägeeinrichtung wiederum die Drittschnitte durchzuführen. Dies natürlich nur an den Teilplatten, an denen Drittschnitte durchgeführt werden müssen.A basic idea of the invention is thus, when dividing the plate or the stack of plates, to process the first and second process sections without considering the third cuts, as is known per se, by first sawing out the plate strips from the raw plate or the raw format by means of the first cuts and then the division into partial plates by means of or the second cuts takes place. Whether only one first or second or several first or second cuts are necessary depends on the pattern to be realized. Both in or before the first stage of the method and in or before the second stage of the method, the per se known trimming cuts can be carried out at the edge of the original plate, if necessary. Gem. The invention, a third method section is now provided. This can be carried out or started subsequently or during the second process section. In this third process section, it is provided to transport at least one of the partial plates or also a plurality of partial plates from the rear transport device of the plate dividing systems back to the or one of the sawing devices in order then to carry out at least a third cut by means of the sawing device so as to saw the partial plate once again and produce the desired final format. A basic idea of the invention is therefore that the one or the sawing device used for the first and / or second cuts is also used for the third cuts, by those sub-plates where third cuts are necessary, by machine by means of return transport again this or one of the sawing devices supplies. The process can be carried out on a wide variety of panel dividing systems. Thus, a panel splitter for performing the method have two different sawing means in the form of the first sawing device for the Erstschnitte and the second sawing device for the second cuts. The third cuts can then be carried out both by the first sawing device and by the second sawing device if the return transport device is designed accordingly. However, methods according to the invention can also be carried out on panel dividing installations which have only a single sawing device. This is possible if, by means of a corresponding return transport device after the first process section, the partial plates for the second process section are optionally returned to the sawing device following a rotation in order then to carry out the second cuts. Accordingly, then gem. the invention by means of the return transport means the sub-plates returned, and then again perform the third cuts with the same sawing. This, of course, only on the part plates, where third cuts must be performed.
Bevorzugte Ausgestaltungsformen der Erfindung sehen vor, dass der oder die Erstschnitte mit einer ersten Sägeeinrichtung der Plattenaufteilanlage entlang einer Schnittlinie der ersten Sägeeinrichtung gesägt werden und dass der oder die Zweitschnitte mit einer zweiten Sägeeinrichtung der Plattenaufteilanlage entlang einer Schnittlinie der zweiten Sägeeinrichtung gesägt werden, wobei die Schnittlinien der Sägeeinrichtungen schräg oder orthogonal zueinander angeordnet sind. Im Fall von einer orthogonalen Anordnung der Schnittlinien der beiden Sägeeinrichtungen spricht man dann auch häufig bei den Erstschnitten von Längsschnitten und bei den Zweitschnitten von Querschnitten oder umgekehrt. Die Schnittlinien müssen aber nicht zwingend orthogonal angeordnet sein, es kann genauso gut sein, dass sie schräg zueinander angeordnet sind. Der Begriff schräg bezeichnet all diejenigen Winkel, die nicht orthogonal und nicht parallel sind. Es ist aber genauso gut auch möglich, dass der oder die Erstschnitte mit einer ersten Sägeeinrichtung der Plattenaufteilanlage entlang einer Schnittlinie der ersten Sägeeinrichtung gesägt werden und dass der oder die Zweitschnitte mit einer zweiten Sägeeinrichtung der Plattenaufteilanlage entlang einer Schnittlinie der zweiten Sägeeinrichtung gesägt werden, wobei die Schnittlinien der Sägeeinrichtungen parallel zueinander angeordnet sind. In diesem Fall befindet sich günstigerweise zwischen der ersten und der zweiten Sägeeinrichtung eine Dreheinrichtung zur Drehung der Plattenstreifen im Anschluss an den ersten Verfahrensabschnitt.Preferred embodiments of the invention provide that the first cut or cuts are sawn with a first sawing device of the plate-splitting installation along a cutting line of the first sawing device and that the second or the second cuts are sawn with a second sawing device of the panel-forming installation along a cutting line of the second sawing device, the cutting lines the sawing means are arranged obliquely or orthogonal to each other. In the case of an orthogonal arrangement of the cutting lines of the two sawing means one then speaks often in the first cuts of longitudinal cuts and in the second cuts of cross-sections or vice versa. However, the cut lines do not necessarily have to be arranged orthogonally, it may just as well be that they are arranged obliquely to one another. The term oblique denotes all those angles which are not orthogonal and not parallel. But it is equally possible that the one or more first cuts are sawn with a first sawing the Plattenaufteilanlage along a cutting line of the first sawing and that the second or the second cuts are sawed with a second sawing the Plattenaufteilanlage along a cutting line of the second Sägeeinrichtung, said Cut lines of the sawing arranged parallel to each other are. In this case, conveniently located between the first and the second sawing means a rotating device for rotating the plate strips following the first process section.
Auch vor dem Durchführen der Drittschnitte kann aber muss nicht ein Drehen der Teilplatte vorgesehen sein. Hierzu ist es günstig, wenn die Teilplatte vor dem Sägen des Drittschnittes von einer Dreheinrichtung der Plattenaufteilanlage, vorzugsweise um eine auf einer Plattenebene der Teilplatte normal stehende gedachte Achse, gedreht wird. Eine Platte weist für gewöhnlich eine Grund- und eine Deckfläche sowie Seiten- bzw. Stirnflächen auf. Die Grund- oder Deckflächen weisen in der Regel eine viel größere Fläche als die Stirn- bzw. Seitenflächen auf. Unter Plattenebene wird in diesem Zusammenhang eine Ebene verstanden, welche parallel zur Grund- und/oder Deckfläche einer Platte bzw. Teil-platte liegt, vorzugsweise durch Grund- oder Deckfläche verläuft.Even before performing the third cuts but can not be provided rotating the sub-plate. For this purpose, it is advantageous if the sub-plate is rotated before sawing the third section of a rotating device of the Plattenaufteilanlage, preferably about an imaginary normal axis on a plate plane of the sub-plate imaginary axis. A plate usually has a base and a top surface and side or end faces. The base or top surfaces usually have a much larger area than the front or side surfaces. In this context, plate plane is understood to mean a plane which lies parallel to the base and / or top surface of a plate or partial plate, preferably runs through the base or cover surface.
Wie bereits erwähnt, müssen in der Regel nicht an allen Teilplatten Drittschnitte durchgeführt werden, meist sind es nur einzelne Teilplatten, welche eines weiteren Zuschnittes bedürfen. In diesem Sinne ist günstigerweise vorgesehen, dass nur eine erste Teilmenge der beim zweiten Verfahrensabschnitt erzeugten Teilplatten ausgesondert, von der Rücktransporteinrichtung zurück transportiert und von der oder einer der Sägeeinrichtungen mittels des zumindest einen Drittschnitts noch einmal zersägt wird und zumindest eine andere Teilmenge der beim zweiten Verfahrensabschnitt erzeugten Teilplatten von einer Weitertransporteinrichtung in einer anderen Transportrichtung weiter transportiert oder anderweitig weiter verarbeitet werden. Bei solchen Ausgestaltungsformen des erfindungsgemäßen Verfahrens können die Teilplatten, welche nicht mittels Drittschnitten weiter zersägt werden müssen, von der Weitertransporteinrichtung bereits einer weiteren Verarbeitung zugeführt werden, während an der ersten Teilmenge der Teilplatten die benötigten Drittschnitte durchgeführt werden.As already mentioned, third cuts do not generally have to be made on all partial plates, usually only individual partial plates, which require a further cut. In this sense, it is expediently provided that only a first subset of the partial plates produced in the second method section is discarded, transported back from the rear transport device and sawn once again by the or one of the sawing devices by means of the at least one third section and at least one other subset in the second method section Partial plates produced transported by a further transport device in another direction of transport or otherwise processed further. In such embodiments of the method according to the invention, the sub-panels, which need not be further sawed by third cuts, are already supplied by the further transport device for further processing, while the required third cuts are performed on the first subset of the sub-panels.
Günstige Ausgestaltungsformen des Verfahrens sehen weiters vor, dass die Teilplatte höchstens mittels eines Drittschnitts zersägt wird. Dies muss aber nicht zwingend so sein, es ist auch denkbar, dass an einer Teilplatte mehr als ein Drittschnitt durchgeführt werden muss. Insbesondere, wenn die Teilplatte nur mittels eines Drittschnittes weiter zersägt werden muss, kann vorgesehen sein, dass zumindest eines der, der aus der Teilplatte gesägten Teile nach dem Drittschnitt von einer Entnahmeeinrichtung entnommen wird ohne vorher einer anderen der Sägeeinrichtungen zugeführt worden zu sein. Dies ist insbesondere dann günstigerweise vorzusehen, wenn die Teilplatte zur Durchführung des Drittschnittes einer ersten Sägeeinrichtung zugeführt wird, welcher in der normalen Transportrichtung noch eine zweite Sägeeinrichtung folgt. Die Entnahmeeinrichtungen können dann dafür sorgen, dass die im Zuge des Drittschnittes hergestellten Teile der Teilplatte vor Erreichen der zweiten Sägeeinrichtung dem normalen Materialfluss entnommen werden.Favorable embodiments of the method further provide that the partial plate is sawn at most by means of a third section. But this does not have to be mandatory be so, it is also conceivable that more than a third section must be performed on a partial plate. In particular, if the sub-plate has to be sawn further only by means of a third cut, it can be provided that at least one of the parts sawed from the sub-plate is removed from a removal device after the third cut without having previously been fed to another of the sawing devices. This is expediently provided, in particular, when the partial plate is fed for carrying out the third cut of a first sawing device, which in the normal transport direction is followed by a second sawing device. The removal devices can then ensure that the parts of the partial plate produced in the course of the third cut are removed from the normal material flow before reaching the second sawing device.
Bevorzugte Ausgestaltungsformen der Erfindung sehen weiters vor, dass der Drittschnitt oder die Drittschnitte entlang von einer oder mehreren, vorzugsweise linearen, Drittschnittlinien gesägt werden, wobei die Drittschnittlinien, bezüglich der Platte gesehen, parallel zu der oder den Erstschnittlinie(n) oder parallel zu der oder den Zweitschnittlinie(n) angeordnet wird (werden).Preferred embodiments of the invention further provide that the third cut or the third cuts are sawn along one or more, preferably linear, third cut lines, the third cut lines, as seen with respect to the plate, being parallel to the first cut line (s) or parallel to or the second cut line (s) is (are) arranged.

Drittschnittlinien 14 der insgesamt an dieser Platte 1 durchzuführenden Erst-, Zweit- und Drittschnitte eingezeichnet, wie sie, bezüglich der Platte 1 gesehen, liegen. Sind alle diese Schnitte in der richtigen Reihenfolge durchgeführt, so ist die Platte 1 in die Teilplatten 8, und soweit notwendig, die Teilplatten 8 in deren Teile 13 zerlegt. Von der Reihenfolge her, werden gem. der Erfindung zunächst die Erstschnitte entlang der Erstschnittlinien 4 im ersten Verfahrensabschnitt durchgeführt. Dabei können vor oder im ersten Verfahrensabschnitt, soweit notwendig, auch Erstschnitte als Besäumschnitte entlang der randlichen Erstschnittlinien 4 durchgeführt werden, um die Randstreifen 18 abzutrennen, welche in der Regel dann Abfall sind. Die mittels der Erstschnitte entstehenden Plattenstreifen 5 werden dann im zweiten Verfahrensabschnitt mittels der Zweitschnitte entlang der Zweitschnittlinien 7 in die Teilplatten 8 zersägt. Dabei können der erste und der letzte Zweitschnitt auch der Besäumung und damit der Abtrennung von Randstreifen 18 dienen.Third cut lines 14 of the total to be performed on this
Im ersten Ausführungsbeispiel dienen die Erstschnitte an den äußeren Erstschnittlinien 4 wie gesagt der Besäumung. Diese kann bei mit entsprechend sauber ausgeführten Rändern versehenen Platten 1 auch entfallen. Durch den Erstschnitt entlang der mittleren Erstschnittlinie 4 wird die Platte 1 in die beiden Plattenstreifen 5 zersägt. All dies geschieht im ersten Verfahrensabschnitt. Anschließend wird der in

Von welcher der Sägeeinrichtungen 3 oder 6 die Drittschnitte durchgeführt werden, kann auch darauf abgestimmt werden, welche der beiden genannten Sägeeinrichtungen 3, 6 bei der Durchführung der Erst- und Zweitschnitte weniger ausgelastet ist, so dass die Durchführung der Drittschnitte die rasche Durchführung der ersten und zweiten Verfahrensabschnitte nicht oder nur möglichst geringfügig verzögert. Die verschiedenen Ausführungsbeispiele zeigen, dass das erfindungsgemäße Verfahren in unterschiedlichsten Ausgestaltungsformen und auf unterschiedlichsten Plattenaufteilanlagen 2 durchgeführt werden kann. Bei den dargestellten Varianten handelt es sich natürlich nur um Beispiele. Hinzuweisen ist noch darauf, dass die Plattenaufteilanlagen 2 durchwegs aus an sich bekannten Einrichtungen und Bauteilen zusammengesetzt werden können. So sind beim Stand der Technik verschiedenste Transporteinrichtungen bekannt, welche jeweils an den genannten Stellen eingesetzt werden können. Das gleiche gilt für Mittel, wie die Anschläge 21 zur Ausrichtung der Platten. Auch Vorschubeinrichtungen 20 und 24 sind in verschiedensten Ausführungsbeispielen beim Stand der Technik im Einsatz. Das Gleiche gilt für die Sägeeinrichtungen 3 und 6 und auch für die Dreheinrichtung 10 sowie für die Entnahmeeinrichtung 17.From which of the
