- the veneers are delivered in stacks on pallets, fed to a gluing device in a separating station and then combined to form veneer packages. Merging can be done in several ways, for example, individually and intermittently with lifting devices as described in US 4,797,169 A, or in a semicontinuous manner with conveyor belts described in. It is common in this art that a strand is to be laid out of the veneers, either sawn or fed as a continuous strand of a press.

- the solution to the problem for the system is that a device for automated transfer of the stack to the main press is arranged in the system.
- the individual manufacturing steps can be automated in an advantageous manner to make the entire process more efficient and cost-effective. It has also proved to be advantageous that in the absence of pre-pressing the veneers a much faster transport and thus shorter residence times of the veneers from the gluing to the main press are possible. This allows in particular the use of highly reactive glues, which can lead to a significant increase in production over the conventional methods and equipment.
- the device for transferring the stack to the main press comprises at least one transport device.
- the device comprises a circulation for stack carriers.
- the stack carriers are suitable to receive the stack formed in or after the stacking device and to transport up to the main press.

- the apparatus may further comprise a second stacking device for forming a package from the stacks.
- the first stacking device could also be suitable for forming packages of several stacks. These packages can, for example, be pressed in a suitable one-day main press to material plates and then, because of lack of glue between the adjacent layers of a stack, separated into individual material plates. Preferably, however, it is provided to spend these packages for a suitable automated storage or directly automated to a separation device and to separate them again there to packages.

- the main press can be designed as a multi-daylight press.
- This main press may alternatively or in combination have its own loading and unloading device for automated feeding of the main press.
- a further embodiment of the device is that for the insertion or arrangement of a release agent between the stacks of a package, an automated device is arranged, which is particularly preferably arranged in the first or second stacking device.

- the compression means are heavy and flat and suitable to suppress or even pre-press a stack of veneers.
- These compression means can also act as a release agent and be marked or recognizable.
- the funds used as a stack carrier can also be used as a compression means, since in the system usually enough of it are available, in particular to this meantime while the production continues to be able to clean.
- suitable and automatable transport devices for transporting the veneers or the stacks, the packages, the compresses and / or the stack carriers can be arranged in the device between the individual individual devices.

- a compression means preferably a stack carrier is deposited as a cover on the stack, so that this compresses the individual layers veneers by its weight and during the automated transport to the main press.
- This stack with double-sided stack carriers, can also be compressed in a pre-press, if the weight of the compression / staple carrier is not sufficient to compress the stack so that it can easily get into the press nip of the main press.
- the stack can be pressed with or without the stack carriers / compression means. By arranging this "cover layer" (compression means) a springing of the veneer stack is avoided until the press and even main presses with a small opening width of the press nip can easily press a high stack.
- Figure 1 shows a schematic structure of a system from the provision of glued and unembossed veneers on the stacking, the automated transfer device and the main press for the production of veneered material panels and an alternative circulation for stacking carrier between the stacking and the main press and after Figure 2 shows a schematic structure of a system according to Figure 1 with a variety of possible variants in terms of the design of the automated device between the stacking device and the main press.
- an exemplary system 1 is shown by the stacking device 8 of veneers 2, 10 to create a material plate 15 after the main press 16.
- the device V can also have a circulation 21, the stack carrier 20, on which at suitable location in the system 1, preferably in the stacking device 8, equipped with stacks 3 of the veneers.
- the circulation 21 may, alternatively for handling the stacks 3 without a base support, provide for automated transport of the stacks 3 to or into or even through the main press 16.
- the stack carriers 20 preferably have holders for press plates, which are pressed with or without grain in the main press 16. Alternatively, of course, the stack carrier 20 itself be designed as press plates.
- FIG. 21 For the sake of clarity, an alternative marking of a circulation 21 for stack carrier 20 has been dispensed with in FIG. It should be noted, however, that this can also be provided in full in all combinations, which represents the figure 2. It should also be noted that in order to avoid a multitude of drawings, an exemplary installation 1 is shown that represents almost all features of the subject of the invention, but the individual features can be left alone and realized in any combination as a device V.
- FIG. 2 therefore shows on the top left the provision of veneers by means of one or more feed devices 4 to a transport device 5.
- different veneers usually of different orientation and quality, are provided in a predetermined order on the transport device 5 and through a gluing device 6, executed here as DINbeleimung, driven and passed as glued veneers 10 to the transport device 7.
- a further feeding device 4 not shown, a non-glued veneer 2 is now inserted in a predetermined sequence in the flow of veneers 10, which will form the unglued cover veneer of a finished material plate 15.
- the transport device 7 transfers the veneers 2, 10 to the stacking device 8, which produces the stack 3 from these.
- the stack 3 consists of an unspecified number of veneers 10 and a non-glued veneer 2 as a cover veneer.
- the stack 3 can now be introduced according to the invention with the transport device 9 directly into the main press 16 and pressed.
- the device V can now have a further stacking device 23 which forms packages 12 from the stacks 3, which consist of at least two stacks 3. Between the stacks is formed by the overhead unglued veneer 2 of the lower stack 3 from a separation point 25, at which the stack 3 can be separated again, since the separation point is not glued.
- the stacking device 8 may be suitable to perform a package formation. This may be necessary in order to achieve higher cycle rates or to be able to form higher parcels 12 in a system if, for example, only a few veneers in a stack 3 are to be pressed. If now a second stacking device 23 is used, this will subsequently require a further transport device 13, which can automatically transfer the packets 12 into a main press 16 for pressing. In this case, after the main press 16, the package would have to be separated from several material plates. Preferably, however, the package is divided again before the main press in a separating device 14 and the stack 3 is pressed individually in a one-day cycle press or in a multi-day press. It can also be provided that a plurality of main presses 16 are arranged in the system, which must be charged.
- the stack 3 may be necessary to pre-press the stack 3 in a pre-press 18. This is usually necessary if by a plurality of veneers 10, the stack 3 apply relatively high or very wavy veneers are present and the stack 3 is too high for the press nip between the heating plates of the main press 16.
- a circulation 21 for stack carrier 20 can also be integrated here.
- the stack carriers are also introduced in the package 12, so that at least one stack carrier is arranged as release agent in the separation point 25 and the separation device 14 facilitates the separation of the stack 3 from each other and in particular simplifies the automation.
- the release agents can also be designed differently, from powders to thin paper, cardboard, foil or sheet metal.
- a laying device can be provided, which applies compression means to each stack 3 or introduces a compression means between the stack 3 during the formation of the package 12 as a release agent.
- the compression means is preferably suitable by its own weight to bring about a compression of the stack 3 or of the pact 12.
- the stack 3 can be automatically introduced directly into the main press 16 with the superposed compression means and pressed, and be removed before the main press 16 again.
- the goal of the compression means is to be able to feed a small press nip of the main press 16 in a targeted manner, without retaining upstanding veneers.
- the compression means which may be designed as a press plate, serve to simplify the transport.
- the compression means can again be a stack carrier, which could greatly simplify the automation of the system, since the circulation would already be present and the means in the system which operate the stack carriers 20 would be the same as for a circulation of the compression means.

The invention relates to a plant for the production of material panels of stacked veneers according to the preamble of claim 1.
Die Herstellung von so genanntem Lagenholz zu Holzplatten ist lange bekannter Stand der Technik. Abstrahiert werden mehrere Lagen aus beleimten Holz, vorzugsweise Bretter oder Furniere aufeinander gelegt und verpresst. Insbesondere unterscheiden sich die beiden Arten Furnierschichtholz und Furniersperrholz darin, dass beim Furniersperrholz die Ausrichtung der einzelnen Lagen zueinander versetzt, vorzugsweise kreuzweise, angeordnet werden, damit man in allen Ausrichtungen die gleiche Zug- und Biegefestigkeiten erhält. Auch wird durch das kreuzweise Verleimen der Furniere die Stabilität und Standfestigkeit gewährleistet, weil das Holz in seinen natürlichen Eigenschaften des Quellens und Schwindens, insbesondere bei Temperaturunterschieden, eingeschränkt wird. Die Erfindung versteht unter Werkstoffplatten insbesondere Furnierschichtholz (gemeint sind vorzugsweise alle Lagenhölzer) welches eine Vielzahl von Verwendungsmöglichkeiten aufweist. Es kann nach oder während der Herstellung mittels einfacher Anpassungen konfiguriert und/oder weiterverarbeitet werden.
The production of so-called plywood wood to wood panels has long been known prior art. Abstracted are several layers of glued wood, preferably boards or veneers superimposed and pressed. In particular, the two types of veneer plywood and veneer plywood differ in that the veneer plywood the alignment of the individual layers offset from each other, preferably crosswise, are arranged so that you get the same tensile and bending strengths in all orientations. Also, the crosswise gluing of the veneers ensures stability and stability, because the wood is limited in its natural properties of swelling and shrinkage, especially in temperature differences. The invention understands material boards in particular laminated veneer lumber (meaning preferably all ply woods) which has a variety of uses. It can be configured and / or further processed after or during manufacture by means of simple adjustments.

Mittlerweile ermöglichen neu entwickelte Leime bevorzugt die Parallelausrichtung der Furniere zueinander, so dass die Herstellung von Furnierschichtholz an Bedeutung zunimmt. Beispielsweise ist es gewünscht bei langlebigen Oberflächenprodukten (Treppenaufbauten oder dergleichen) einen Abschliff zu ermöglichen, ohne dass die nachfolgende Lage eine andere Orientierung der Faserrichtung aufweist.
Meanwhile, newly developed glues preferably allow the veneers to be aligned in parallel, so that the production of laminated veneer lumber becomes more important. For example, in the case of durable surface products (staircase structures or the like), it is desired to allow a grinding without the subsequent layer having a different orientation of the fiber direction.

Unter Furnier versteht ein Fachmann unter einem bis mehrere Millimeter dicke Blätter aus Holz. Diese können aus verschiedenen Hölzern und mittels verschiedener Techniken, meist angepasst an die vorliegenden Hölzer, hergestellt werden. Die am meisten verbreiten Herstellungsverfahren sind das Messer- und das Schälverfahren. Ein Furnier, dass vorzugsweise im Holzbau eingesetzt wird, besteht aus circa 3 mm starken Schälfurnieren aus Nadelholz und wird mit Phenolharz zu Platten oder Trägern bis hin zu Balken verpresst.
Veneers are understood by a specialist to be one to several millimeters thick sheets of wood. These can be made of different woods and using different techniques, usually adapted to the present woods. The most widely used manufacturing processes are the knife and the peeling process. A veneer, which is preferably used in timber construction, consists of about 3 mm thick peeled veneer softwood and is pressed with phenolic resin to plates or carriers to beams.

Eine Verpressung erfolgt entweder taktweise in Etagenpressen oder kontinuierlich in Doppelbanddurchlaufpressen, die ebenfalls bereits in der holzverarbeitenden Industrie bekannt und eingeführt.
Compression takes place either intermittently in floor presses or continuously in double belt presses, which are also already known and introduced in the woodworking industry.

In den bekannten und automatisierten Herstellungsverfahren werden die Furniere stapelweise auf Paletten angeliefert, in einer Vereinzelungsstation einer Beleimungsvorrichtung zugeführt und anschließend zu Furnierpaketen zusammengelegt. Die Zusammenlegung kann auf mehreren Arten erfolgen, beispielsweise einzeln und taktweise mit Hubvorrichtungen wie in US 4,797,169 A beschrieben, oder in semikontinuierlicher Weise mit Förderbändern, beschrieben in. Diesem Stand der Technik ist gemein, dass aus den Furnieren ein Strang gelegt werden soll, der entweder zersägt oder als kontinuierlicher Strang einer Presse zugeführt werden soll. Zu diesem Zwecke werden umständlich Rampen an dem Strang angelegt, die entweder in oder entgegen der Produktionsrichtung ansteigend angeordnet sind, um über die Stufen eine durchgehende Verbindung des Stranges zu erzielen.
In the known and automated manufacturing processes, the veneers are delivered in stacks on pallets, fed to a gluing device in a separating station and then combined to form veneer packages. Merging can be done in several ways, for example, individually and intermittently with lifting devices as described in US 4,797,169 A, or in a semicontinuous manner with conveyor belts described in. It is common in this art that a strand is to be laid out of the veneers, either sawn or fed as a continuous strand of a press. For this purpose, awkward ramps are applied to the strand, which are arranged either rising in or against the production direction in order to achieve a continuous connection of the strand through the steps.

Im Unterschied hierzu ist bekannt mittels Vorrichtungen eine schnelle und automatisierte Herstellung von Stapeln aus Furnieren automatisiert anzustreben. Dennoch werden bis heute die fertigen Furnierstapel von Hand zu Furnierpaketen zusammengeführt und in einer Vorpresse vorgepresst. Die Vorpresse ist üblicherweise nur als reine Druckpresse ausgeführt und bringt keine Wärme in die Furnierstapel oder –pakete ein. Bei dem nachgeschalteten manuellen Entstapeln lassen sich dann die Stapel des Paketes einfacher voneinander trennen, da der Leim trotz fehlender Wärme Adhäsionskräfte entwickelt, die ausreichend ist die vorgepressten Furnierpakete einfacher voneinander zu trennen. Ein anderer Grund für eine Vorpressung ist, dass üblicherweise die Heißpressen in Ein- oder Mehretagenausführung eine hohen Zuführöffnungen für den Stapel an Furnieren aufweisen, so dass ein komprimierter Stapel an Furnieren sich händisch einfacher und zielgerichteter in den Pressspalt der Presse einführen lassen kann.
In contrast, it is known to aim automatically by means of a fast and automated production of stacks of veneers. Nevertheless, until today, the finished veneer stacks are brought together by hand to veneer packages and pre-pressed in a pre-press. The pre-press is usually designed only as a pure printing press and does not introduce heat into the veneer stacks or packages. In the subsequent manual destacking then the stacks of the package can be separated easily from each other, since the glue develops despite the lack of heat adhesion forces, which is sufficient to separate the pre-pressed veneer packages easier from each other. Another reason for pre-pressing is that usually the hot presses in single or multi-day execution have high feed openings for the stack of veneers, so that a compressed stack of veneers can be introduced manually easier and more targeted in the press nip of the press.

Im Zuge der Globalisierung, der Fortentwicklung der Leime und besonders durch die technische Weiterentwicklung der verwendeten kontinuierlich arbeitenden Presse ist es möglich zum einen eine höhere Anzahl an Furnieren in einem Paket, respektive in einem Strang zu verpressen und/oder den Durchsatz pro Stunde signifikant zu erhöhen.

Der Erfindung liegt die Aufgabe zugrunde, eine Anlage zur Herstellung von Werkstoffplatten aus gestapelten Furnieren zu schaffen, mit der kostengünstig und flexibel produziert werden kann. In einer Erweiterung der Aufgabe soll es mit der Anlage möglich sein basierend auf den vorgegebenen Furnieren unterschiedlichste Arten an Werkstoffplatten, herzustellen, wobei insbesondere der Transportweg von einer Stapelstation zur Bildung von Stapeln aus Furnieren hin zur Presse verbessert und flexibel ausgestaltet werden soll.

Eine Anlage zur Herstellung von Werkstoffplatten aus gestapelten Furnieren umfasst im Wesentlichen eine Transportvorrichtung für Furniere zu einer Stapelvorrichtung zur Erstellung eines Stapels aus diesen Furnieren und zumindest eine Hauptpresse zur Herstellung einer verpressten Werkstoffplatte aus dem gebildeten Stapel an Furnieren. Die Stapel zeichnen sich in der Regel dadurch aus, dass das oberste Furnier im Gegensatz zu den unteren Furnieren keine Oberflächenbeleimung aufweist. Hierzu wird bekannter Weise auf der Transportvorrichtung zur Stapelvorrichtung in vorgegebenen Abständen eine unbeleimtes Furnier zwischen beleimten Furnieren angeordnet, wobei das unbeleimte Furnier dann die Deckschicht eines Stapels und damit der späteren Werkstoffplatte bildet.
A plant for producing material plates from stacked veneers essentially comprises a transport device for veneers to a stacking device for producing a stack of these veneers and at least one main press for producing a compressed material plate from the stack of veneers formed. The stacks are usually characterized by the fact that the top veneer, in contrast to the bottom veneer has no surface gluing. For this purpose, a non-glued veneer between glued veneers is arranged on the transport device for stacking device at predetermined intervals, wherein the unembellished veneer then forms the top layer of a stack and thus the subsequent material plate.

Die nachfolgenden beschriebenen Vorteile und Weiterbildungen der Erfindung können alternativ oder in beliebiger Kombination angewendet werden, um auf die Gegebenheiten vor Ort und vor allem auf die Eigenschaften und Größenverhältnisse der Furniere abzustellen.
The following described advantages and developments of the invention can be used alternatively or in any combination to focus on the local conditions and especially on the properties and size ratios of the veneers.

Indem einzelne Arbeitsschritte, wie zum Beispiel das oben genannte Vorpressen im Einzelfall entfallen können, lassen sich die einzelnen Fertigungsschritte in vorteilhafter Art und Weise automatisieren um den gesamten Prozessablauf effizienter und kostengünstiger zu gestalten. Es hat sich ebenfalls als vorteilhaft herausgestellt, dass bei dem Wegfall des Vorpressens der Furniere ein deutlich schnellerer Transport und damit kürzere Verweilzeiten der Furniere von der Beleimung bis hin zur Hauptpresse möglich sind. Dies erlaubt insbesondere den Einsatz von hochreaktiven Leimen, was zu einer deutlicheren Produktionssteigerung gegenüber den herkömmlichen Verfahren und Anlagen führen kann.
By individual steps, such as the above-mentioned pre-pressing can be omitted in an individual case, the individual manufacturing steps can be automated in an advantageous manner to make the entire process more efficient and cost-effective. It has also proved to be advantageous that in the absence of pre-pressing the veneers a much faster transport and thus shorter residence times of the veneers from the gluing to the main press are possible. This allows in particular the use of highly reactive glues, which can lead to a significant increase in production over the conventional methods and equipment.

In einer weiteren Ausgestaltung umfasst die Vorrichtung einen Umlauf für Stapelträger. Die Stapelträger sind dabei geeignet die gebildeten Stapel in oder nach der Stapelvorrichtung aufzunehmen und bis hin zur Hauptpresse zu transportieren. In vorteilhafter Weise können die Stapelträger auch direkt in die Hauptpresse mit einem aufliegendem Stapel eingefahren werden, entleeren dort den Stapel in die Hauptpresse oder verbleiben während des Pressvorganges vor Ort und sorgen für die Entladung des verpressten Stapels respektive der Werkstoffplatte.
In a further embodiment, the device comprises a circulation for stack carriers. The stack carriers are suitable to receive the stack formed in or after the stacking device and to transport up to the main press. Advantageously, the stack carrier can also be moved directly into the main press with a resting stack, emptying there the stack in the main press or remain during the pressing process on site and ensure the discharge of the compressed stack respectively the material plate.

Advantageously, the stack carrier can also be moved directly into the main press with a resting stack, emptying there the stack in the main press or remain during the pressing process on site and ensure the discharge of the compressed stack respectively the material plate.
In einer Alternative oder sogar in Kombination kann die Vorrichtung weiter eine zweite Stapelvorrichtung zur Bildung eines Pakets aus den Stapeln umfassen. Alternativ oder in Kombination könnte aber auch die erste Stapelvorrichtung geeignet sein Pakete aus mehreren Stapeln zu bilden. Diese Pakete können beispielsweise in einer geeigneten Einetagen-Hauptpresse zu Werkstoffplatten verpresst werden und werden anschließend, mangels Leim zwischen den angrenzenden Schichten eines Stapels, zu einzelnen Werkstoffplatten aufgetrennt. Bevorzugt ist es aber vorgesehen, diese Pakete zu einer geeigneten automatisierten Lagerhaltung oder direkt automatisiert zu einer Trennvorrichtung zu verbringen und diese dort wieder zu Paketen aufzutrennen.
In an alternative, or even in combination, the apparatus may further comprise a second stacking device for forming a package from the stacks. Alternatively or in combination, however, the first stacking device could also be suitable for forming packages of several stacks. These packages can, for example, be pressed in a suitable one-day main press to material plates and then, because of lack of glue between the adjacent layers of a stack, separated into individual material plates. Preferably, however, it is provided to spend these packages for a suitable automated storage or directly automated to a separation device and to separate them again there to packages.

Im Zuge der Paketbildung aus Stapeln der Furniere kann die Stapelvorrichtung geeignet sein an einem Paket Markierungen zur Kenntlichmachung der Trennstelle zwischen den Stapeln anzubringen. Diese Markierungen sind in der automatisierten Trennvorrichtung dazu geeignet die Trennung genau an der Trennstelle durchzuführen. Bei einer Verpressung des Paketes in der Hauptpresse sind diese Markierungen besonders geeignet die gebildeten Werkstoffplatten genauer voneinander zu trennen, ohne übermäßigen Schaden an den Trennstellen zu hinterlassen.
In the course of package formation from stacking the veneers, the stacking device may be suitable to attach to a package markings to identify the separation point between the stacks. These markings are suitable in the automated separation device to perform the separation exactly at the separation point. When a compression of the package in the main press, these markers are particularly suitable to separate the formed material plates more accurately from each other without leaving excessive damage to the separation points.

In einer weiteren alternativen oder fortbildenden Ausgestaltung kann die Vorrichtung eine Vorpresse zur Komprimierung der Furniere umfassen, bevorzugt zur Bildung eines Komprimats aus einem Stapel oder aus einem Paket, welches aus mehreren Stapeln besteht. Eine derartige Vorpresse kann beispielsweise als Taktpresse oder als ein ein- oder mehrfacher Walzenstuhl ausgebildet sein.
In a further alternative or further development, the device may comprise a pre-press for compressing the veneers, preferably for forming a compact from a stack or from a package consisting of several stacks. Such a pre-press can be designed, for example, as a cycle press or as a single or multiple roll mill.

Zusätzlich oder alternativ kann die Vorrichtung eine Trennvorrichtung zur Aufteilung des Komprimats aus der Vorpresse wieder in einzelne Stapel umfasst. Diese Trennvorrichtung kann dabei Mittel zur automatisierten Erkennung der Trennstellen zwischen den Stapeln aufweisen und wird besonders bevorzugt die Mechanismen zur Trennung der einzelnen Stapel voneinander automatisiert ansteuern.
Additionally or alternatively, the device may comprise a separating device for dividing the compressed material from the pre-press into individual stacks again. This separating device can have means for automated detection of the separation points between the stacks and is particularly preferably the mechanisms for separating the individual stacks from each other automatically control.

Bevorzugt kann die Hauptpresse als Mehretagenpresse ausgeführt sein. Diese Hauptpresse kann alternativ oder in Kombination eine eigene Be- und Entladevorrichtung zur automatisierten Beschickung der Hauptpresse aufweisen.
Preferably, the main press can be designed as a multi-daylight press. This main press may alternatively or in combination have its own loading and unloading device for automated feeding of the main press.

Eine weitere Ausgestaltung der Vorrichtung besteht darin, dass zur Einlage oder Anordnung eines Trennmittels zwischen den Stapeln eines Paketes eine automatisierte Vorrichtung angeordnet ist, welches besonders bevorzugt in der ersten oder zweiten Stapelvorrichtung angeordnet wird.
A further embodiment of the device is that for the insertion or arrangement of a release agent between the stacks of a package, an automated device is arranged, which is particularly preferably arranged in the first or second stacking device.
A further embodiment of the device is that for the insertion or arrangement of a release agent between the stacks of a package, an automated device is arranged, which is particularly preferably arranged in the first or second stacking device.
Besonders bevorzugt können dabei die Stapelträger als Trennmittel im Paket angeordnet werden, so dass die Stapelträger bei der Paketbildung nicht nur als Träger des Paketes dienen sondern mit gestapelt als Trennmittel im Paket angeordnet werden. In einer positiven Ausgestaltung sind die Stapelträger im wesentlichen flächiger ausgebildet als das Format des Stapels aus Furnieren.
Particularly preferably, the stack carrier can be arranged as a release agent in the package, so that the stack carrier used in the package formation not only serve as a carrier of the package but are stacked as a release agent in the package. In a positive embodiment, the stack carrier are formed substantially flat than the format of the stack of veneers.

In a positive embodiment, the stack carrier are formed substantially flat than the format of the stack of veneers.
In einer alternativen oder zusätzlichen Ausgestaltung der Erfindung kann in der automatisierten Vorrichtung der Anlage noch eine Auflegevorrichtung zur Auflage eines Kompressionsmittels auf den Stapel angeordnet sein. Bevorzugt sind die Kompressionsmittel schwer und flächig und geeignet einen Stapel an Furnieren niederzuhalten oder sogar vorzupressen. Diese Kompressionsmittel können ebenfalls als Trennmittel wirken und entsprechend markiert oder erkennbar sein. Der Einfachheit halber können die als Stapelträger verwendeten Mittel auch als Kompressionsmittel Verwendung finden, da in der Anlage üblicherweise genug davon vorhanden sind, insbesondere um diese zwischenzeitlich während die Produktion weiterläuft, reinigen zu können.
In an alternative or additional embodiment of the invention, a laying device for supporting a compression means may be arranged on the stack in the automated device of the system. Preferably, the compression means are heavy and flat and suitable to suppress or even pre-press a stack of veneers. These compression means can also act as a release agent and be marked or recognizable. For simplicity, the funds used as a stack carrier can also be used as a compression means, since in the system usually enough of it are available, in particular to this meantime while the production continues to be able to clean.

Besonders hervorzuheben wäre die Möglichkeit die Kompressionsmittel und/oder die Trennmittel und/oder die Stapelträger als Pressbleche auszuführen und in der Vorrichtung anzuordnen. Natürlich besteht auch die Möglichkeit an den Kompressionsmitteln, den Trennmitteln oder den Stapelträgern austauschbare Pressbleche mit unterschiedlicher Musterung anzubringen.
Particularly noteworthy would be the possibility to carry out the compression means and / or the release agent and / or the stack carrier as press plates and to arrange in the device. Of course, it is also possible to attach to the compression means, the release agents or the stack carriers exchangeable press plates with different patterns.

Abschließend sei noch darauf hingewiesen, dass in der Vorrichtung zwischen den einzelnen Einzelvorrichtungen geeignete und automatisierbare Transportvorrichtungen zum Transport der Furniere respektive der Stapel, der Pakete, der Komprimate und/oder der Stapelträger angeordnet sein können.
Finally, it should be pointed out that suitable and automatable transport devices for transporting the veneers or the stacks, the packages, the compresses and / or the stack carriers can be arranged in the device between the individual individual devices.
Finally, it should be pointed out that suitable and automatable transport devices for transporting the veneers or the stacks, the packages, the compresses and / or the stack carriers can be arranged in the device between the individual individual devices.
In einer besonders vorteilhaften Ausführungsform der Anlage wird in oder nach einer Stapelvorrichtung der Stapel auf die Stapelträger angeordnet, anschließend wird ein Kompressionsmittel, vorzugsweise wieder ein Stapelträger als Deckblech auf den Stapel abgelegt, so dass dieser durch sein Gewicht die einzelnen Schichten Furniere zusammendrückt und während des automatisierten Transportes zur Hauptpresse fixiert. Somit kann auch ein Hochgeschwindigkeitstransport durchgeführt werden, ohne dass Teile des Stapels verrutschen oder verloren gehen. Dieser Stapel, mit beidseitigen Stapelträgern, kann zusätzlich noch in einer Vorpresse komprimiert werden, wenn das Eigengewicht des Kompressionsmittels/Stapelträgers nicht ausreicht, den Stapel so zu komprimieren, dass er problemlos in den Pressspalt der Hauptpresse gelangen kann. Dabei kann der Stapel je nach Ausführungsform der Anlage mit oder ohne die Stapelträger/Kompressionsmittel verpresst werden. Durch die Anordnung dieser „Deckschicht“ (Kompressionsmittels) wird ein Auffedern des Furnierstapels bis vor die Presse vermieden und auch Hauptpressen mit einer geringen Öffnungsweite des Pressspaltes können einen hohen Stapel problemlos verpressen.
In a particularly advantageous embodiment of the system, the stack is placed on the stack carrier in or after a stacking device, then a compression means, preferably a stack carrier is deposited as a cover on the stack, so that this compresses the individual layers veneers by its weight and during the automated transport to the main press. Thus, high-speed transport can also be performed without parts of the stack slipping or being lost. This stack, with double-sided stack carriers, can also be compressed in a pre-press, if the weight of the compression / staple carrier is not sufficient to compress the stack so that it can easily get into the press nip of the main press. Depending on the embodiment of the system, the stack can be pressed with or without the stack carriers / compression means. By arranging this "cover layer" (compression means) a springing of the veneer stack is avoided until the press and even main presses with a small opening width of the press nip can easily press a high stack.

In der Zeichnung wird eine beispielhafte Anlage 1 von der Stapelvorrichtung 8 von Furnieren 2, 10 bis zur Erstellung einer Werkstoffplatte 15 nach der Hauptpresse 16 dargestellt.
In the drawing, an exemplary system 1 is shown by the stackingdevice 8 of veneers 2, 10 to create a material plate 15 after the main press 16.
In the drawing, an exemplary system 1 is shown by the stacking
Hierbei werden Furniere bereitgestellt und an ihrer Oberfläche beleimt. Diese beleimten Furniere 10 werden nun in vorgegebener Anzahl mit einem weiteren Furnier 2, welches nicht auf der Oberseite beleimt ist, der Stapelvorrichtung 8 mit einer Transportvorrichtung 7 zugeführt und in der Stapelvorrichtung 8 zu Stapel 3 gestapelt. Dabei findet sich das unbeleimte Furnier 2 als Deckfurnier oben auf dem Stapel 3. Der Stapel 3 wird anschließend automatisiert mit der Vorrichtung V der Hauptpresse 16 übergeben und zu einer Werkstoffplatte 15, respektive einem Furnierschichtholz, verpresst und der Endfertigung (Pfeil) zugeführt. In einer alternativen Ausführungsform kann die Vorrichtung V auch einen Umlauf 21 aufweisen, der Stapelträger 20, auf denen an geeigneter Stelle in der Anlage 1, bevorzugt in der Stapelvorrichtung 8, mit Stapeln 3 der Furniere bestückt. Der Umlauf 21 kann, alterativ zur Handhabung der Stapel 3 ohne einen Grundträger, für einen automatisierten Transport der Stapel 3 zur oder in oder sogar durch die Hauptpresse 16 hindurch, sorgen. Bevorzugt weisen die Stapelträger 20 Halterungen für Pressbleche auf, die mit oder ohne Maserung in der Hauptpresse 16 verpresst werden. Alternativ können natürlich die Stapelträger 20 selbst als Pressbleche ausgeführt sein.
Here veneers are provided and glued on their surface. These gluedveneers 10 are now supplied in a predetermined number with a further veneer 2, which is not glued on top, the stacking device 8 with a transport device 7 and stacked in stacking device 8 to stack 3. The stack 3 is then automatically transferred with the device V of the main press 16 and pressed to a material plate 15, respectively a veneer plywood, and the final production (arrow) supplied. In an alternative embodiment, the device V can also have a circulation 21, the stack carrier 20, on which at suitable location in the system 1, preferably in the stacking device 8, equipped with stacks 3 of the veneers. The circulation 21 may, alternatively for handling the stacks 3 without a base support, provide for automated transport of the stacks 3 to or into or even through the main press 16. The stack carriers 20 preferably have holders for press plates, which are pressed with or without grain in the main press 16. Alternatively, of course, the stack carrier 20 itself be designed as press plates.
Here veneers are provided and glued on their surface. These glued
Der Übersichtlichkeit halber wurde in Figur 2 auf eine alternative Einzeichnung eines Umlaufes 21 für Stapelträger 20 verzichtet. Es sei aber darauf hingewiesen, dass dieser auch vollumfänglich in allen Kombinationen, die die Figur 2 darstellt, vorgesehen sein kann. Weiter sei darauf hingewiesen, dass zur Vermeidung einer Vielzahl an Zeichnungen, bewußt eine exemplarische Anlage 1 dargestellt ist, die nahezu alle Merkmale des Gegenstandes der Erfindung darstellt, aber die einzelnen Merkmale für sich alleine gestellt und in jeglicher Kombination als Vorrichtung V verwirklicht werden können.
For the sake of clarity, an alternative marking of acirculation 21 for stack carrier 20 has been dispensed with in FIG. It should be noted, however, that this can also be provided in full in all combinations, which represents the figure 2. It should also be noted that in order to avoid a multitude of drawings, an exemplary installation 1 is shown that represents almost all features of the subject of the invention, but the individual features can be left alone and realized in any combination as a device V.
For the sake of clarity, an alternative marking of a
Figur 2 zeigt demnach links oben die Bereitstellung von Furnieren mittels einer oder mehrerer Zuführvorrichtungen 4 auf eine Transportvorrichtung 5. Hierbei bevorzugt in schneller Abfolge verschiedene Furniere 2, meist unterschiedlicher Ausrichtung und Qualität in einer vorgegebenen Reihenfolge auf der Transportvorrichtung 5 bereitgestellt und durch eine Beleimvorrichtung 6, hier als Teppichbeleimung ausgeführt, gefahren und als beleimte Furniere 10 an die Transportvorrichtung 7 übergeben. Mittels einer nicht weiter dargestellten weiteren Zuführvorrichtung 4 wird nun ein unbeleimtes Furnier 2 in vorgegebener Reihenfolge in den Fluss an Furnieren 10 eingefügt, welches das unbeleimte Deckfurnier einer fertigen Werkstoffplatte 15 bilden wird.
FIG. 2 therefore shows on the top left the provision of veneers by means of one ormore feed devices 4 to a transport device 5. Here, preferably in rapid succession, different veneers 2, usually of different orientation and quality, are provided in a predetermined order on the transport device 5 and through a gluing device 6, executed here as Teppichbeleimung, driven and passed as glued veneers 10 to the transport device 7. By means of a further feeding device 4 not shown, a non-glued veneer 2 is now inserted in a predetermined sequence in the flow of veneers 10, which will form the unglued cover veneer of a finished material plate 15.
FIG. 2 therefore shows on the top left the provision of veneers by means of one or
Die Transportvorrichtung 7 übergibt die Furniere 2, 10 an die Stapelvorrichtung 8, welche aus diesen den Stapel 3 herstellt. Im Folgenden besteht der Stapel 3 aus einer nicht näher bestimmten Anzahl an Furnieren 10 und einem unbeleimten Furnier 2 als Deckfurnier. Der Stapel 3 kann nun gemäß der Erfindung mit der Transportvorrichtung 9 direkt in die Hauptpresse 16 eingeführt und verpresst werden.
Thetransport device 7 transfers the veneers 2, 10 to the stacking device 8, which produces the stack 3 from these. In the following, the stack 3 consists of an unspecified number of veneers 10 and a non-glued veneer 2 as a cover veneer. The stack 3 can now be introduced according to the invention with the transport device 9 directly into the main press 16 and pressed.
The
In einer weiteren Ausgestaltung kann die Vorrichtung V nun eine weitere Stapelvorrichtung 23 aufweisen, die aus den Stapeln 3 Pakete 12 bildet, die zumindest aus zwei Stapeln 3 bestehen. Zwischen den Stapeln bildet sich durch das obenliegende unbeleimte Furnier 2 des unteren Stapels 3 eine Trennstelle 25 aus, an der die Stapel 3 wieder getrennt werden können, da die Trennstelle nicht beleimt ist.
In a further embodiment, the device V can now have a further stackingdevice 23 which forms packages 12 from the stacks 3, which consist of at least two stacks 3. Between the stacks is formed by the overhead unglued veneer 2 of the lower stack 3 from a separation point 25, at which the stack 3 can be separated again, since the separation point is not glued.
In a further embodiment, the device V can now have a further stacking
Alternativ oder sogar in Kombination, kann auch die Stapelvorrichtung 8 geeignet sein, eine Paketbildung vorzunehmen. Dies kann notwendig sein, um höhere Taktraten zu erreichen oder höhere Pakete 12 in einer Anlage bilden zu können, wenn beispielsweise nur wenige Furniere in einem Stapel 3 verpresst werden sollen. Wird nun eine zweite Stapelvorrichtung 23 verwendet, wird diese nachfolgend eine weitere Transportvorrichtung 13 benötigen, die die Pakete 12 in eine Hauptpresse 16 zur Verpressung automatisiert übergeben kann. In diesem Falle würde nach der Hauptpresse 16 das Paket aus mehreren Werkstoffplatten voneinander getrennt werden müssen. Bevorzugt wird aber das Paket vor der Hauptpresse in einer Trennvorrichtung 14 wieder aufgeteilt und die Stapel 3 einzeln in einer Einetagen-Taktpresse oder in einer Mehretagen-Presse verpresst. Es kann auch vorgesehen sein, dass in der Anlage mehrere Hauptpressen 16 angeordnet sind, die beschickt werden müssen.
Alternatively, or even in combination, the stackingdevice 8 may be suitable to perform a package formation. This may be necessary in order to achieve higher cycle rates or to be able to form higher parcels 12 in a system if, for example, only a few veneers in a stack 3 are to be pressed. If now a second stacking device 23 is used, this will subsequently require a further transport device 13, which can automatically transfer the packets 12 into a main press 16 for pressing. In this case, after the main press 16, the package would have to be separated from several material plates. Preferably, however, the package is divided again before the main press in a separating device 14 and the stack 3 is pressed individually in a one-day cycle press or in a multi-day press. It can also be provided that a plurality of main presses 16 are arranged in the system, which must be charged.
Alternatively, or even in combination, the stacking
Besonders bei Mehretagenpressen als Hauptpresse 16 kann es notwendig sein, die Stapel 3 in einer Vorpresse 18 vorzupressen. Dies ist meist dann notwendig, wenn durch eine Vielzahl an Furnieren 10 die Stapel 3 relativ hoch auftragen oder sehr wellige Furniere vorliegen und der Stapel 3 zu hoch für den Pressspalt zwischen den Heizplatten der Hauptpresse 16 ist.
Especially with multi-day presses as themain press 16, it may be necessary to pre-press the stack 3 in a pre-press 18. This is usually necessary if by a plurality of veneers 10, the stack 3 apply relatively high or very wavy veneers are present and the stack 3 is too high for the press nip between the heating plates of the main press 16.
Especially with multi-day presses as the
Dargestellt ist in der Figur 2 als eine weitere Alternative, dass das Paket 12 in der Vorpresse 18 zu einem Komprimat 17 verdichtet worden ist, meist um Taktzeiten zu verbessern. In der Vorpresse wird eine erste Bindung zwischen den Furnieren erreicht, die aber in der Regel wieder auffedert. In vorteilhafter Weise wird aber die nicht beleimte Seite der Furniere 10 in der Vorpresse 18 schon einmal mit dem Leim benetzt was in der Hauptpresse 18 Vorteile bei der Verpressung bietet. Besteht das Komprimat nun aus mehreren Stapeln 3 kann dieser wie bereits ausgeführt auch direkt in einer Hauptpresse verpresst werden, wobei meist Einetagenpressen zum Einsatz kommen. Bei einer Mehretagenpresse als Hauptpresse 16 wird aber in der Regel eine Trennvorrichtung 14 zur Anwendung kommen, die an den Trennstellen 22 die Stapel 3 voneinander trennt und an die Hauptpresse 16 übergibt. Es kann dabei dahingestellt bleiben, ob eine weitere Transportvorrichtung direkt in die Etage der Hauptpresse 16 fördert oder ob die Hauptpresse eine eigene automatisierte Beschick- und Entladevorrichtung 24 aufweist, solange gemäß der Erfindung nach das Beschicken der Hauptpresse 16 automatisiert stattfindet.
Is shown in Figure 2 as a further alternative that thepackage 12 has been compressed in the pre-press 18 to a Komprimat 17, usually to improve cycle times. In the pre-press, a first bond between the veneers is achieved, but usually rebounds. Advantageously, however, the non-glued side of the veneers 10 in the pre-press 18 is already wetted once with the glue which offers 18 advantages in the pressing in the main press. If the print now consists of several stacks 3, this can also be pressed directly into a main press, as already stated, whereby one-day presses are usually used. In a multi-daylight press as the main press 16 but usually a separator 14 will be used, which separates the stack 3 from each other at the separation points 22 and passes to the main press 16. It may be left undecided whether another transport device promotes directly into the floor of the main press 16 or whether the main press has its own automated loading and unloading device 24, as long as according to the invention after the loading of the main press 16 takes place automatically.
Is shown in Figure 2 as a further alternative that the
In weiteren vorteilhaften Ausgestaltungen, die nicht näher in der Figur 2 dargestellt ist, kann auch hier ein Umlauf 21 für Stapelträger 20 integriert sein.
In further advantageous embodiments, which is not shown in more detail in FIG. 2, acirculation 21 for stack carrier 20 can also be integrated here.
In further advantageous embodiments, which is not shown in more detail in FIG. 2, a
In einer weiteren bevorzugten Ausführungsform werden die Stapelträger auch im Paket 12 eingebracht, so dass in der Trennstelle 25 zumindest immer ein Stapelträger als Trennmittel angeordnet ist und der Trennvorrichtung 14 die Trennung der Stapel 3 voneinander erleichtert und insbesondere die Automa-tisierung vereinfacht. Die Trennmittel können natürlich auch anders ausge-staltet sein, von Pulver bis hin zu dünnem Papier, Karton, Folie oder Blech.
In a further preferred embodiment, the stack carriers are also introduced in thepackage 12, so that at least one stack carrier is arranged as release agent in the separation point 25 and the separation device 14 facilitates the separation of the stack 3 from each other and in particular simplifies the automation. Of course, the release agents can also be designed differently, from powders to thin paper, cardboard, foil or sheet metal.
In a further preferred embodiment, the stack carriers are also introduced in the
In einer ebenfalls nicht dargstellten Ausgestaltung der Vorrichtung kann eine Auflegevorrichtung vorgesehen sein, die Kompressionsmittel auf jeden Stapel 3 auflegt oder zwischen die Stapel 3 während der Bildung des Paketes 12 ein Kompressionsmittel als Trennmittel einführt. Das Kompressionsmittel ist vorzugsweise geeignet durch sein Eigengewicht eine Verdichtung des Stapels 3 respektive des Paktes 12 herbeizuführen. Auch hier kann in jeglicher Alternative der Stapel 3 direkt mit dem aufliegenden Kompressionsmittel automatisiert in die Hauptpresse 16 eingeführt und verpresst werden, als auch vor der Hauptpresse 16 wieder entfernt werden. Das Ziel des Kompressionsmittel ist es, einen geringen Pressspalt der Hauptpresse 16 zielgereicht beschicken zu können, ohne dass aufstehende Furniere zurückgehalten werden. Auch kann das Kompressionsmittel, welches als Pressblech ausgeführt sein kann, zur Vereinfachung des Transportes dienen.
In a likewise not illustrated embodiment of the device, a laying device can be provided, which applies compression means to eachstack 3 or introduces a compression means between the stack 3 during the formation of the package 12 as a release agent. The compression means is preferably suitable by its own weight to bring about a compression of the stack 3 or of the pact 12. Again, in any alternative, the stack 3 can be automatically introduced directly into the main press 16 with the superposed compression means and pressed, and be removed before the main press 16 again. The goal of the compression means is to be able to feed a small press nip of the main press 16 in a targeted manner, without retaining upstanding veneers. Also, the compression means, which may be designed as a press plate, serve to simplify the transport.
In a likewise not illustrated embodiment of the device, a laying device can be provided, which applies compression means to each
Besonders bevorzugt kann das Kompressionsmittel wiederum ein Stapelträger sein, was die Automatisierung der Anlage deutlich vereinfachen könnte, da bereits der Umlauf vorhanden wäre und die Mittel in der Anlage, die die Stapelträger 20 umlaufend betreiben die gleichen wären wie für einen Umlauf der Kompressionsmittel.
Particularly preferably, the compression means can again be a stack carrier, which could greatly simplify the automation of the system, since the circulation would already be present and the means in the system which operate thestack carriers 20 would be the same as for a circulation of the compression means.
