Abstract

The plasterboard, chipboard or fibrous sheets are brought to a collection station (3) by a conveyer (1) with two rotating pressure rollers (2). The rollers may move vertically. A suction head (5) between two rollers may stop the lowermost sheet and the sheets may be assembled in groups of three. Laths or battens (4) are lifted up between pairs of rollers to lift up each stack of three sheets in turn and to allow sheets to cool in separate groups.

Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Ablegen von Platten. Dabei sollen die Platten einzeln von einer Transporteinrichtung antransportiert und auf einer Ablageebene zumindest paarweise aufeinandergelegt werden. Die Erfindung bezieht sich dabei insbesondere auf unbeschichtete Span-, OSB-, MDF- und andere Faserplatten.The present invention relates to a device for depositing plates. The plates should be individually transported by a transport device and be stacked on a storage level at least in pairs. The invention refers in particular to uncoated chip, OSB, MDF and other fiberboard.

Bei der Herstellung und weiteren Verarbeitung von Platten unterschiedlichster Art ist es häufig erforderlich, die Platten einzeln zu transportieren. Dabei kann es aus Taktzeitgründen erwünscht sein, sie zu kleineren Paketen von übereinanderliegenden Platten aufeinander zu legen, um andere Arbeitsschritte mit diesen Paketen durchführen zu können.In the production and further processing of plates of various kinds It is often necessary to transport the plates individually. It may be due to clock time reasons be desired to smaller packages of superimposed Laying plates on each other to perform other operations with these packages to be able to.

Ein wichtiger und von der Erfindung besonders berücksichtigter Anwendungsfall ist die Handhabung von einzelnen aus einer Plattenproduktionspresse gelieferten Platten beim Einlegen in eine Wendeeinrichtung oder in Kühlfächer einer Kühleinrichtung, beispielsweise eines Kühlsternwenders oder Kühligelwenders oder eines Kühlpaternosters. In solchen Kühleinrichtungen laufen die Kühlfächer entlang einer vorgegebenen Bahn zyklisch um und transportieren die Platten entlang eines Teils dieser Bahn, um diese zu kühlen. Bei dünnen Platten werden dabei häufig einige Platten pro Kühlfach eingelegt. Dazu werden sie auf der Ablageebene, die sich im Moment des Einlegens in dem Kühlfach befindet, übereinander gelegt, um dann von dem Kühlfach weitertransportiert zu werden. Ähnliches gilt für Wendeeinrichtungen. Die Erfindung richtet sich jedoch auch auf denkbare andere Situationen, in denen zwei oder mehrere Platten nach einem Einzeltransport zu kleinen Paketen aufeinandergelegt werden sollen.An important and particularly considered by the invention application is the handling of individual plates delivered from a plate making press when inserted in a turning device or in cooling compartments of a cooling device, for example, a Kühlsternwenders or Kühligelwenders or a Kühlpaternosters. In such cooling devices, the cooling compartments run along a predetermined one Loop cyclically and transport the plates along a part of this Track to cool these. In the case of thin plates, there are often a few plates inserted per refrigerated compartment. They will do this at the filing level, which is at the moment of insertion in the refrigerated compartment is superimposed, then from to be transported to the refrigerated compartment. The same applies to turning facilities. However, the invention is also directed to conceivable other situations in which two or more plates stacked after a single transport into small packages should be.

Der Erfindung liegt das technische Problem zugrunde, eine Vorrichtung und ein Verfahren anzugeben, die ein effizientes und zuverlässiges Ab- und Aufeinanderlegen der Platten auf der Ablageebene gestatten.The invention is based on the technical problem of a device and a method specify an efficient and reliable separation and superposition allow the plates on the storage level.

Erfindungsgemäß ist dazu einerseits vorgesehen eine Vorrichtung zum Ablegung von dünnen Platten mit einer Transporteinrichtung, die dazu ausgelegt ist, die Platten einzeln zu einer Ablageebene zu transportieren und auf der Ablageebene abzulegen und dabei zumindest paarweise aufeinander zu legen, gekennzeichnet durch eine Ansaugeinrichtung, die ausgelegt ist zum Ansaugen der unteren der aufeinandergelegten Platten und der auf dieser abgelegten Platte durch die untere Platte hindurch,
und andererseits ein Verfahren zum Ablegen von dünnen Platten mit der obigen Vorrichtung und den Schritten: Transportieren der Platten zu der Ablageebene und Ablegen der Platten auf der Ablageebene zumindest paarweise aufeinander und Ansaugen der unteren und der daraufliegenden der aufeinanderliegenden Platten, wobei die auf der unteren Platte liegende Platte durch die untere Platte hindurch angesaugt und somit gehalten wird.According to the invention on the one hand provided for a device for depositing thin plates with a transport device which is designed to transport the plates individually to a storage level and store on the storage level and thereby at least in pairs to put on each other, characterized by a suction device which is designed for sucking the lower of the stacked plates and the plate deposited thereon through the lower plate,
and, on the other hand, a method of depositing thin plates with the above apparatus and the steps of: transporting the plates to the depositing plane and depositing the plates on the depositing plane at least in pairs and sucking the lower and subsequent ones of the superposed plates, those on the lower plate lying plate is sucked through the lower plate and thus held.

Bevorzugte Ausgestaltungen sind in den abhängigen Ansprüchen angegeben.Preferred embodiments are specified in the dependent claims.

Die Erfindung geht von der Erkenntnis aus, dass es gerade bei dünnen Platten zu wesentlichen Problemen führen kann, wenn eine beim Aufeinanderlegen der Platten zwischen den Platten verbleibende Luftschicht nicht schnell und effizient abgebaut wird. Infolge des relativ geringen Gewichts der dünnen Platten bleiben diese auf der Luftschicht und damit aufeinander gleitfähig und können sehr leicht gegeneinander verrutschen. Eine sichere Positionierung ist somit nicht oder nur für die unterste Platte möglich. Hierbei ist anzumerken, dass die Ablageebene bei der Erfindung auch schräg liegen kann, also nicht notwendigerweise horizontal liegen muss. Aber auch bei schrägen Ablageebenen können sich infolge von sehr leicht verrutschenden Platten in dem Plattenpaket Probleme ergeben.The invention is based on the recognition that it is especially with thin plates can cause significant problems if one when stacking the plates between the plates remaining air layer is not degraded quickly and efficiently becomes. Due to the relatively low weight of the thin plates these remain on the Air layer and thus each other lubricious and can easily against each other slip. A secure positioning is therefore not or only for the lowest plate possible. It should be noted that the storage level in the invention also can lie diagonally, so does not necessarily have to be horizontal. But also at oblique shelves can be due to very easily slipping plates problems in the disk pack.

Ferner haben die Erfinder festgestellt, dass viele relativ dünne Platten eine gewisse Restdurchlässigkeit für Luft aufweisen, also dass sich bei Erzeugen eines Vakuums unter der untersten Platte ein Ansaugeffekt auch durch diese Platte hindurch für die darüberliegende Platte ergibt. Die auf der untersten Platte liegende nächste Platte kann also durch die unterste Platte hindurch angesaugt werden, womit beide Platten wirksam positioniert und insbesondere zumindest stellenweise ohne verbleibende Luftschicht zueinander in Kontakt gebracht werden können, um eine ausreichende Haftreibung zwischen den Platten aufzubauen.Further, the inventors have found that many relatively thin plates have some Having residual permeability to air, so that when generating a vacuum under the lowest plate a suction effect also through this plate for the overlying plate results. The next plate lying on the lowest plate So it can be sucked through the bottom plate, bringing both plates effectively positioned and in particular at least in places without remaining Air layer can be brought into contact with each other to a sufficient Stiction between the plates build up.

Daraus ergibt sich, dass sich die Erfindung nur auf solche dünnen Platten richtet, die eine ausreichende Luftdurchlässigkeit zeigen, insbesondere auf dünne Holzwerkstoffplatten mit einer zwischen den Fasern, Spänen oder Streifen verbleibenden Porosität.It follows that the invention is directed only to such thin plates, the show sufficient air permeability, especially on thin wood-based panels with a porosity remaining between the fibers, chips or strips.

Es hat sich sogar herausgestellt, dass sich die Erfindung auch noch in Bezug auf die Positionierung der drittuntersten Platte, also insbesondere der obersten Platte in einem Dreierpaket, durchführen lässt. Selbst durch zwei Platten hindurch lässt sich bei ausreichend starkem Vakuum ein geeigneter Ansaugeffekt für diese dritte Platte erzielen. Die Erfindung richtet sich also insbesondere auf das Aufeinanderlegen von zwei oder drei Platten.It has even been found that the invention also in relation to the Positioning of the third lowest plate, so in particular the top plate in one Triplet, lets run. Even through two plates can be at sufficiently strong vacuum to achieve a suitable suction effect for this third plate. The invention is therefore directed in particular to the juxtaposition of two or three plates.

Ein wichtiger Anwendungsfall liegt darin, dass die Platten von einer Transportbahn, insbesondere einer mit Transportriemen oder -rollen aufgebauten Bahn, angeliefert werden. Dabei kann die Transportbahn die erfindungsgemäße Transporteinrichtung sein, die die Platten aufeinanderlegt. Sie kann allerdings die Platten auch zu einer anderen Transporteinrichtung herantransportieren, die diese Aufgabe übernimmt. Diese andere Transporteinrichtung kann beispielsweise eine Rolle und vorzugsweise ein Rollenpaar zum Transport der Platten zwischen den beiden Rollen sein. Die Rolle bzw. das Rollenpaar kann die Platten dann in einer für das Ablegen auf einer möglicherweise zuvor auf der Ablageebene bereits abgelegten Platte geeigneten Höhe auf die Ablageebene führen. Insbesondere können die Rolle oder das Rollenpaar die Platten von einem Transportniveau der Transportbahn zu diesem Zweck etwas anheben.An important application is that the plates from a transport path, in particular a constructed with transport belt or rollers track delivered become. In this case, the transport path, the transport device according to the invention be the one who puts the plates on top of each other. She can, however, the plates to one transport another transport device, which takes over this task. This other transport means may for example be a roller and preferably a pair of rollers to transport the plates between the two roles be. The role or the pair of rolls may then place the plates in one for one previously on the storage level already stored plate appropriate height lead the storage level. In particular, the role or the pair of rollers can Raise plates from a transport level of the conveyor track slightly for this purpose.

In der Ablageebene selbst kann ebenfalls eine angetriebene Rollenbahn vorgesehen sein. Diese Rollenbahn kann aber auch nichtangetriebene, d.h. freilaufende oder gebremste Rollen aufweisen. Zwischen oder unter den Rollen können dabei eine oder mehrere Vakuumsauger oder Ansaugeinrichtungen vorgesehen sein.In the storage level itself can also be a driven roller conveyor provided his. This roller conveyor can also be non-driven, i. free-wheeling or braked Have roles. Between or under the roles can be a or several vacuum suction or suction devices may be provided.

Die Ablageebene ist vorzugsweise so positioniert, dass sie in zyklischer Folge in Kühlfächern der bereits erwähnten Kühleinrichtung angeordnet ist, so dass die Plattenpakete jeweils in den Kühlfächern gebildet werden können. Die Kühlfächer können beispielsweise durch rechenartige Greifarme eines sternförmigen, igelförmigen oder paternosterartigen Kühlwenders voneinander abgegrenzt sein. Solche Kühleinrichtungen sind an sich bekannt und müssen daher nicht im Einzelnen dargestellt werden. Ähnliches gilt für Wendeeinrichtungen mit Fächern für die Platten, etwa einen Sternwender. Bevorzugt ist eine Anordnung von Ansaugöffnungen der Ansaugeinrichtung in einem relativ nah an der im Sinne der Transportrichtung zu der Ablageebene hinteren Kante. Hierbei wird von der Lage dieser Kante im ruhenden Zustand der Platten ausgegangen. Die Ansaugöffnungen können vorzugsweise in Bezug auf die Erstreckung der Platten in der Plattentransportrichtung zu der Ablageebene im an die Kante anschließenden Drittel vorgesehen sein. Beim Aufeinanderlegen der Platten kommt es erfahrungsgemäß vor allem in diesem hinteren Bereich zu einer Luftkissenbildung zwischen den Platten, so dass die Ansaugeinrichtung hier besonders wirkungsvoll ist. Weitere Ansaugöffnungen außerhalb dieses Bereichs sind denkbar, bei dem bevorzugten Ausführungsbeispiel jedoch nicht vorgesehen.The storage plane is preferably positioned so as to be in a cyclical sequence in FIG Refrigeration compartments of the aforementioned cooling device is arranged, so that the plate packs can be formed in each case in the cooling compartments. The refrigerators can for example, by rake-like gripping arms of a star-shaped, egg-shaped or paternoster-type Kühlwenders be delimited from each other. Such cooling devices are known per se and therefore need not be presented in detail become. The same applies to turning facilities with subjects for the plates, about one Turner. An arrangement of suction openings of the suction device is preferred in a relatively close to that in the direction of the transport direction to the storage level rear edge. This is the position of this edge in the dormant state the plates went out. The suction openings may preferably with respect to on the extension of the plates in the disc transport direction to the storage level be provided in the adjoining the third third. When stacked The plates experience, especially in this rear area an air cushion formation between the plates, so that the suction device here is particularly effective. Other intake openings outside this range are conceivable, but not provided in the preferred embodiment.

Dabei können zumindest zwei Vakuumsauger nebeneinander vorgesehen sein, wobei eine Verbindungslinie zwischen den Ansaugöffnungen dabei im Wesentlichen parallel zu der erwähnten Kante liegen kann.In this case, at least two vacuum suction can be provided side by side, wherein a connecting line between the intake ports thereby substantially can lie parallel to the mentioned edge.

Die Transportrichtung zu der Ablageebene kann vorzugsweise parallel zu einer Drehachse der Wende- oder Kühleinrichtung angeordnet sein. Sie kann jedoch auch senkrecht dazu verlaufen (wobei sich die Transportrichtung und die Drehachse nicht schneiden müssen). The transport direction to the storage level may preferably be parallel to a Rotary axis of the turning or cooling device can be arranged. She can, however run perpendicular to it (where the transport direction and the axis of rotation is not have to cut).

Im Folgenden wird ein Ausführungsbeispiel dargestellt, wobei die einzelnen Merkmale auch in anderen Kombinationen oder einzeln erfindungswesentlich sein können. Insbesondere wird ausdrücklich darauf hingewiesen, dass die vorstehende und die nachfolgende Beschreibung sowohl im Hinblick auf den Verfahrenscharakter als auch auf den Vorrichtungscharakter der Erfindung zu verstehen sind.In the following an embodiment is shown, wherein the individual features in other combinations or individually may be essential to the invention. In particular, it is expressly stated that the foregoing and the following description, both with regard to the nature of the method Also to understand the device character of the invention.

Die Figur zeigt eine stark schematisierte Seitenansicht einer erfindungsgemäßen Vorrichtung.The figure shows a highly schematic side view of an inventive Device.

Dabei ist mit 1 summarisch eine Rollentransportbahn dargestellt, die einzelne Platten zu einem Rollenpaar 2 mit in Bezug zu der Transportbahn übereinanderliegenden Rollen transportieren kann. An das Rollenpaar 2 schließt sich eine Verlängerung 3 der Rollentransportbahn an, die eine Ablageebene definiert. Zwischen einzelne der Rollenachsen der Rollenbahn 3 greifen in der Figur im Schnitt dargestellte Rechenzinken 4 eines Kühlsternwenders, zwischen denen horizontale und in der Figur im Schnitt dargestellte Kühlfächer begrenzt sind.It is summarized with 1 a roller conveyor, the individual plates to a pair of rollers 2 with respect to the transport path superimposed Can transport roles. To the pair of rollers 2, an extension 3 closes the roller transport path, which defines a storage level. Between each of the Roller axes of the roller conveyor 3 engage in the figure shown in section rake tines 4 of a Kühlsternwenders, between which horizontal and in the figure in Section shown cooling compartments are limited.

Einzelne Platten werden von der Rollentransportbahn 1 zu dem Rollenpaar 2 gebracht und von dem Rollenpaar 2 auf die Ablageebene auf der Rollenbahn 3 gelegt. Dabei kann das Rollenpaar 2 nachfolgende Platten auf bereits auf der Ablageebene liegende Platten auflegen. Dazu kann das Rollenpaar 2, wie in der Figur dargestellt, auf dem Niveau der Rollentransportbahn 1, jedoch etwas über dem Niveau der nachfolgenden Ablageebene angebracht sein, alternativ dazu kann das Rollenpaar 2 allerdings auch vertikal beweglich sein. Dann können die Rollentransportbahn 1 und die Ablageebene auf einem gemeinsamen Niveau liegen. Das Rollenpaar 2 kann dann die zweite und die dritte Platte auf die bereits auf der Ablageebene liegende(n) Platte(n) auflegen. Dabei werden Pakete von drei aufeinanderliegenden Platten gebildet. Danach tritt ein weiterer Satz Rechenzinken 4 zwischen den Rollenachsen der Rollenbahn 3 nach oben und hebt das Plattenpaket ab, so dass nachfolgende Platten in ein neues Kühlfach eingelegt werden. Die nach oben weitertransportierten Kühlfächer enthalten also jeweils Dreierpakete von Platten. Die Transportbewegungen des Kühlsternwenders und damit der in der Figur dargestellten Rechenzinken 4 erfolgt getaktet, könnten jedoch auch kontinuierlich sein. Entscheidend ist lediglich, dass die in der Figur dargestellten Rechenzinken 4 die Platten erst dann von der Rollenbahn 3, also der Ablageebene, anheben, wenn die Dreierpaketbildung abgeschlossen ist.Individual plates are brought from the roller conveyor 1 to the pair of rollers 2 and placed by the pair of rollers 2 on the storage level on the roller conveyor 3. In this case, the pair of rollers 2 subsequent plates already on the storage level Place lying panels. For this purpose, the pair of rollers 2, as shown in the figure, at the level of the roller conveyor 1, but slightly above the level of the following Alternatively, the pair of rollers 2 can be attached also be vertically movable. Then, the roller conveyor 1 and the storage level is on a common level. The pair of rollers 2 can then the second and the third plate on the already on the storage level lying (n) Place plate (s). In this case, packets are formed by three superimposed plates. Thereafter, another set of computer tines 4 occurs between the roller axes of Roller conveyor 3 upwards and lifts the plate pack, so that subsequent plates be placed in a new refrigerator compartment. The further transported to the top Coolers therefore each contain triple packages of plates. The transport movements the Kühlsternwenders and thus the illustrated in the figure computing tines. 4 is clocked, but could also be continuous. The only thing that matters is that the computing prongs 4 shown in the figure, the plates only from the roller conveyor 3, ie the storage level, lift when the triple package formation completed is.

In der Nähe der dem Rollenpaar 2 zugewandten Kante der Ablageebene bzw. der Rollenbahn 3 sind Vakuumsauger 5 angebracht, von denen eines in der Figur dargestellt ist und ein weiteres hinter oder vor der Zeichenebene liegt, wobei die Verbindungslinie zwischen den beiden Vakuumsaugern 5 parallel zu den Rollenachsen und senkrecht zu der Zeichenebene steht. Die Vakuumsauger 5 weisen nach oben gerichtete Ansaugöffnungen auf, durch die die erste unterste Platte angesaugt und gehalten wird, jedoch auch die zweite darauf aufgelegte Platte und sogar die dritte letzte Platte angesaugt werden, so dass diese in dem Bereich über den Vakuumsaugern 5 aneinander angesaugt und durch Haftreibung aufeinander gehalten werden. Damit können die Platten wirksam abgebremst und kann ein unkontrolliertes Verrutschen der Platten in den Kühlfächern verhindert werden. Wenn diese einmal stabil aufeinander liegen, sorgt die Haftreibung zwischen den Platten dafür, dass sie, wenn der Kühlsternwender das Kühlfach weiter nach oben transportiert, auch im Wesentlichen stabil liegen bleiben.In the vicinity of the roller pair 2 facing edge of the storage level or the Roller conveyor 3, vacuum cups 5 are mounted, one of which is shown in the figure is and another lies behind or in front of the drawing plane, being the connecting line between the two vacuum cups 5 parallel to the roller axes and is perpendicular to the drawing plane. The vacuum cups 5 point upwards Suction on, through which sucked the first bottom plate and but also the second record placed on it and even the third one sucked last plate so that these are in the area above the vacuum cups 5 sucked together and held each other by static friction. Thus, the plates can effectively braked and can be an uncontrolled slipping the plates in the refrigerators are prevented. If this once stable lie on one another, the stiction between the plates ensures that they, if the Kühlsternwender the cooling compartment further transported upwards, also essentially remain stable.

Die Vakuumsauger 5 sind vertikal beweglich und können beim Einlaufen der ersten Platte nach unten bewegt werden, um keine Kollision mit der ersten Platte hervorzurufen. Wenn die Vorderkante der ersten Platte über sie hinwegbewegt wurde, können sie nach oben gefahren werden, um die erste Platte und darauffolgend auch die zweite und die dritte Platte anzusaugen. Im Übrigen sind sie vorzugsweise mit einer Dichtlippe aus einem elastischen Kunststoff versehen.The vacuum cups 5 are vertically movable and can when entering the first Plate to be moved down to avoid causing a collision with the first plate. If the leading edge of the first plate has been moved over it, you can they are driven up to the first plate and subsequently the suck in the second and the third plate. Otherwise, they are preferably with one Sealing lip made of an elastic plastic.

Im rechten Bereich der Figur ist ein nicht dargestellter Sicherheitsanschlag vorgesehen, an den die Platten anstoßen können, wenn die Wirkung der Ansaugeinrichtung 5 nicht ausreichen sollte.In the right part of the figure, an unillustrated safety stop is provided, to which the plates can abut when the effect of the suction device 5 should not be enough.
