Description

Die Erfindung betrifft ein Verfahren und eine Anlage zum Bilden von Stapeln aus stabförmigen Gegenständen mit den Merkmalen der Oberbegriffe der unabhängigen Ansprüche 1 und 4. Für das Bilden von Stapeln oder Paketen aus stabförmigen Gegenständen sind verschiedene Vorschläge bekannt, die oft aufwändig und störanfällig sind.The invention relates to a method and a system for forming stacks from rod-shaped objects with the features of the preambles of independent claims 1 and 4. Various proposals are known for forming stacks or packages from rod-shaped objects, which are often complex and prone to failure.

Bei dem in WO 2013/074019 A1 geoffenbarten Verfahren werden mehrere Stücke Schnittholz nebeneinanderliegend auf einem Förderband bereitgestellt, indem sie gegen einen Anschlag bewegt werden. Danach werden die Stücke Schnittholz auf ein weiteres Förderband bewegt, wobei sich wegen unterschiedlicher Fördergeschwindigkeiten zwischen den Stücken Schnittholz Abstände ergeben, so dass auf dem weiteren Förderband Stücke Schnittholz vereinzelt bewegt werden. Auf einem dritten Förderband werden Pakete aus mehreren, nunmehr wieder unmittelbar aneinander anliegenden Stücken Schnittholz gebildet. Diese Pakete werden schlussendlich zum Bilden eines Stapels aus Schnittholz übereinandergelegt. Dabei werden Pakete stets auf bereits abgelegte Pakete gelegt.At the in WO 2013/074019 A1 disclosed method multiple pieces of lumber are provided side by side on a conveyor belt by being moved against a stop. Thereafter, the pieces of lumber are moved onto a further conveyor belt, with distances arising between the pieces of lumber due to different conveying speeds, so that pieces of lumber are moved individually on the further conveyor belt. On a third conveyor belt, packages are formed from several pieces of sawn timber that are now directly adjacent to one another. These packs are ultimately stacked to form a stack of lumber. Packages are always placed on top of packages that have already been stored.

Bei CH 513 061 A werden Stücke Schnittholz ungeordnet in Form eines Haufens bereitgestellt. Aus diesem Haufen werden Stücke Schnittholz mit Hilfe einer als "Vereinzelner" wirkenden Fördereinrichtung, in der Stücke Schnittholz mit Abstand voneinander (vereinzelt) bewegt werden, zu einem Förderband gefördert. Von diesem Förderband werden Stücke Schnittholz abgenommen und von oben her auf einen Stapel bewegt, wobei zwischen Lagen Schnittholz Stapellatten eingelegt werden. Gezeigt und beschrieben ist in EP 0 888 829 A2 eine Vorrichtung zum Sortieren von Schnittholz. Die bekannte Vorrichtung weist eine Sortiertrommel auf, die nicht zum Vereinzeln von Stücken Schnittholz geeignet ist, sondern in ihren Fächern jeweils mehrere Stücke Schnittholz, die ein einheitliches Sortierkriterium haben, aufnimmt. Der Sortiertrommel entnommene Stücke Schnittholz können zu Paketen zusammengefasst werden. Beschrieben ist in DE 35 11 993 A1 ein Verfahren zum Sortieren und Einlegen von Leisten. Stücke Schnittholz werden aus Haufen, in denen sie ungeordnet liegen, zu einem Elevator bewegt, mit dem sie vereinzelt nach oben bewegt und dann vom oberen Ende des Elevators weg von oben her auf einen Stapel Schnittholz abgelegt werden. Dem Elevator werden Stücke Schnittholz aus Zwischenlagern, die voneinander verschiedene Sorten Schnittholz enthalten, zugeführt. JP H03 186517 A offenbart ein Verfahren und eine Anlage nach den Oberbegriffen der Ansprüche 1 und 4.at CH 513 061 A pieces of lumber are provided in a disorderly manner in the form of a heap.

Eine Anlage 1 zum Bilden von Stapeln 11 aus stabförmigen Gegenständen, im Beispiel Latten 27, umfasst eine Lattenkiste 2, in der stabförmige Gegenstände, die im gezeigten Ausführungsbeispiel Latten 27 aus Holz, aus Metall (z.B. Aluminium) oder aus Kunststoff sind, angeordnet bevorratet sind.A system 1 for forming stacks 11 of rod-shaped objects, in the example slats 27, comprises a crate 2 in which rod-shaped objects, which in the exemplary embodiment shown are slats 27 made of wood, metal (e.g. aluminum) or plastic, are arranged and stored .

Aus der Lattenkiste 2 werden Latten 27 in Form eines ungeordneten Haufens auf eine Fördereinrichtung 3 gelegt.From the crate 2 slats 27 are placed on a conveyor 3 in the form of a disorderly heap.

Latten 27 können händisch aus der Lattenkiste 2 entnommen und auf die Fördereinrichtung 3 gelegt werden. Alternativ kann eine Umsetzeinrichtung eingesetzt werden, mit der Latten 27 ohne händisches Zutun auf die Fördereinrichtung gelegt werden.Slats 27 can be removed manually from the slat box 2 and placed on the conveyor 3. Alternatively, a transfer device can be used with which the slats 27 can be placed on the conveyor device without manual intervention.

Die Fördereinrichtung 3 fördert Latten 27 zu einer Vereinzelungsvorrichtung 4. Im Anschluss an die Vereinzelungsvorrichtung 4 ist eine Einrichtung 5 zum Prüfen der Qualität von Latten 27 vorgesehen, die eine Kamera 15 aufweist. Im Anschluss an die Vereinzelungsvorrichtung 4 ist eine weitere Fördereinrichtung 6 vorgesehen, die vereinzelte und bezüglich Qualität geprüfte Latten 27 zu einer Einrichtung 7 zum Bilden von Stapeln 11 aus Latten 27 fördert.The conveyor device 3 conveys slats 27 to a separating device 4 . Following the separating device 4 , a device 5 for checking the quality of slats 27 is provided, which has a camera 15 . Following the separating device 4 , a further conveyor device 6 is provided, which conveys the separated slats 27 that have been checked for quality to a device 7 for forming stacks 11 from slats 27 .

In der Einrichtung 7 zum Bilden von Stapeln 11 werden Latten 27 in einem Schacht 18 nach und nach nach oben bewegt, sodass ein Stapel 11 aus übereinandergelegten Latten 27 gebildet wird. Dabei kann eine Hebeeinrichtung vorgesehen sein, die beispielsweise mit Hilfe von Hebefingern in dem Schacht 18 vorhandene Latten 27 (oder eine einzelne Latte 27) anhebt, sodass von der Fördereinrichtung 6 eine weitere Latte 27 unterhalb von im Schacht 18 angeordneten Latten 27 in den Schacht 18 bewegt werden kann. Sobald eine weitere Latte 27 in den Schacht 18 hineingeschoben ist, werden bereits im Schacht 18 enthaltene Latten 27 auf die "neue" Latte 27 aufgesetzt. Dem Schacht 18 kann eine an den Enden der im Schacht 18 aufgenommenen Latten 27 angreifende Halteeinrichtung, z.B. eine Klemmeinrichtung oder dgl., zugeordnet sein, so dass Latten 27 im Schacht 18 in angehobener Stellung gehalten werden, wenn die Hebeeinrichtung wegbewegt wird, um das Zuführen einer "neuen" Latte 27 nicht zu behindern.In the device 7 for forming stacks 11, slats 27 are gradually moved upwards in a chute 18, so that a stack 11 of slats 27 placed one on top of the other is formed. A lifting device can be provided, which lifts slats 27 (or a single slat 27) present in the shaft 18, for example with the help of lifting fingers, so that another slat 27 can be moved into the shaft 18 below arranged in the shaft 18 slats 27. As soon as another slat 27 is pushed into the shaft 18, slats 27 already contained in the shaft 18 are placed on the "new" slat 27. The chute 18 can be associated with a holding device, eg a clamping device or the like, gripping the ends of the slats 27 received in the chute 18, so that slats 27 are held in the raised position in the chute 18 when the lifting device is moved away for feeding not to impede a "new" bar 27.

Alternativ können die Wände 21 des Schachtes 18 von einem Stellantrieb aufeinander zu verstellbar sein, um einen Stapel 11 aus Latten 27 in angehobener Stellung klemmend zu halten.Alternatively, the walls 21 of the chute 18 may be adjustable towards one another by an actuator to clamp a stack 11 of slats 27 in the raised position.

Am unteren Ende des Schachtes 18 ist eine Öffnung 19 vorgesehen, durch die Latten 27 unterhalb eines Leitbleches 20 in den Schacht 18 bewegt werden.At the lower end of the shaft 18 there is an opening 19 through which the slats 27 can be moved into the shaft 18 below a guide plate 20 .

Der Schacht 18 zum Bilden von Stapeln 11 aus Latten 27 hat zwei Wände 21, die in ihren oberen Bereichen 29 voneinander weg abgebogen sind.The chute 18 for forming stacks 11 of slats 27 has two walls 21 which are bent away from each other in their upper portions 29.

In der Einrichtung 7 gebildete Stapel 11 aus Latten 27 werden von einem Lattengreifer 8 mit zwei Backen erfasst und in ein Fach 10 eingelegt. In dem Fach 10 werden die Latten 27 für die weitere Verwendung der Latten 27 vorrätig gehalten. Beispielsweise sind die Fächer 10 Bestandteil einer Lattenlegung 9. Aus den Fächern 10 der Lattenlegung 9 entnommene Latten 27 werden beispielsweise zwischen Lagen Schnittholz angeordnet, um zwischen den Lagen aus Schnittholz Freiraum (Luft) zu bilden. In jedes Fach 10 der Lattenlegung 9 wird ein Stapel 11 aus Latten 27 eingelegt. In jedes der Fächer 10 oder in einzelne der Fächer 10, beispielsweise der Lattenlegung, kann auch mehr als ein Stapel 11 aus Latten 27 eingelegt werden.Stacks 11 of slats 27 formed in the device 7 are gripped by a slat gripper 8 with two jaws and placed in a compartment 10 . In the compartment 10, the slats 27 are kept in stock for further use of the slats 27. For example, the compartments 10 are part of a lath 9. Laths 27 taken from the compartments 10 of the lath 9 are arranged, for example, between layers of sawn wood in order to form free space (air) between the layers of sawn wood. A stack 11 of slats 27 is inserted into each compartment 10 of the slat laying 9 . More than one stack 11 of slats 27 can also be inserted into each of the subjects 10 or into individual subjects 10, for example the slat laying.

Am Ende der Fördereinrichtung 3, welche Latten 27 ungeordnet zur Vereinzelungseinrichtung 4 fördert, ist eine Gleitbahn 12 vorgesehen, entlang der Latten 27 zu einer Trommel 13 der Vereinzelungseinrichtung 4 gleiten. Die Trommel 13 weist auf ihrem Umfang Vertiefungen 14 (oder Mitnehmer) auf, die radial nach außen hin offen sind, wobei in jeder Vertiefung 14 eine Latte 27 aufgenommen wird und zu der weiteren Fördereinrichtung 6 bewegt wird. Auf der Fördereinrichtung 6 werden die Latten 27 einzeln und mit Abstand voneinander zu der Einrichtung 7 zum Bilden von Stapeln 11 bewegt.At the end of the conveyor device 3, which conveys slats 27 in a disordered manner to the separating device 4, a slideway 12 is provided, along which the slats 27 slide to a drum 13 of the separating device 4. The drum 13 has indentations 14 (or drivers) on its circumference, which are open radially outwards, with a slat 27 being received in each indentation 14 and being moved to the further conveyor device 6 . On the conveyor 6, the slats 27 are moved individually and at a distance from one another to the device 7 for forming stacks 11.

Oberhalb der Vereinzelungseinrichtung 4 ist die Kamera 15 der Einrichtung 5 zum Prüfen der Qualität von Latten 27 angeordnet. Wenn die Einrichtung 5 eine fehlerhafte Latte 27 feststellt, wird eine am Ende der weiteren Fördereinrichtung 6 vorgesehene Ausschussklappe 16, die eine Fördereinrichtung umfasst, so verschwenkt, dass ihr in Bewegungsrichtung von Latten 27 auf der Fördereinrichtung 6 vorderes Ende nach oben bewegt wird, um eine Öffnung in der Fördereinrichtung 6 freizugeben, durch welche Öffnung die fehlerhafte Latte 27 entlang einer Gleitfläche 17 nach unten gleitet. Sobald die fehlerhafte Latte 27 ausgeschieden ist, sich also unter der Ausschlussklappe 16 auf die Gleitfläche 17 bewegt hat, wird die Ausschlussklappe 16 wieder nach unten verschwenkt, sodass Latten 27 weiter unterhalb des Leitbleches 20 in die Öffnung 19 des Schachtes 18 der Einrichtung 7 zum Bilden von Stapeln 11 aus Latten 27 bewegt werden. An Stelle der Ausschussklappe 16 kann auch ein, beispielsweise in Längsrichtung der Fördereinrichtung 6 verschiebbar gelagerter, Deckel vorgesehen sein. Der Deckel kann aus seiner die Öffnung in der Fördereinrichtung 6 überdeckende Lage wegbewegt werden, so dass eine fehlerhafte Latte 27 ausgeschieden werden kann, indem die Latte 27 durch die jetzt freie Öffnung in der Fördereinrichtung 6 nach unten auf die Gleitfläche 17 fallen gelassen wird. Dann wird der Deckel wieder in seine die Öffnung in der Fördereinrichtung 6 verschließende Stellung zurückbewegt.The camera 15 of the device 5 for checking the quality of slats 27 is arranged above the separating device 4 . If the device 5 detects a faulty slat 27, a reject flap 16 provided at the end of the further conveyor 6, which comprises a conveyor, is pivoted in such a way that its front end in the direction of movement of slats 27 on the conveyor 6 is moved upwards by one Release opening in the conveyor 6, through which opening the faulty slat 27 slides along a sliding surface 17 down. As soon as the faulty slat 27 has been eliminated, i.e. has moved under the exclusion flap 16 onto the sliding surface 17, the exclusion flap 16 is pivoted downwards again, so that slats 27 move further below the guide plate 20 into the opening 19 of the shaft 18 of the device 7 for forming be moved by stacks 11 of slats 27. Instead of the scrap flap 16, a cover, for example mounted so as to be displaceable in the longitudinal direction of the conveyor device 6, can also be provided. The cover can be moved from its position covering the opening in the conveyor 6 so that a faulty slat 27 can be rejected by letting the slat 27 fall down onto the sliding surface 17 through the now free opening in the conveyor 6. Then the lid again moved back into its opening in the conveyor 6 closing position.

Der Lattengreifer 8 ist an einem mehrachsigen Roboter 24 angeordnet und wird von diesem bewegt, um Stapel 11 aus Latten 27 aus der Einrichtung 7 zum Bilden von Stapeln 11 zu einem Fach 10, das beispielsweise ein Fach 10 einer Lattenlegung 9 ist, zu bewegen.The slat gripper 8 is arranged on a multi-axis robot 24 and is moved by this in order to move stacks 11 of slats 27 from the device 7 for forming stacks 11 to a compartment 10 which is, for example, a compartment 10 of a slat laying 9 .

Der Roboter 24 - es können auch zwei oder mehr als zwei Roboter 24 vorgesehen sein - ist auf einer Brücke 25 verfahrbar, sodass er Stapel 11 aus Latten 27 aufnehmen und in ein gewünschtes Fach 10 beispielsweise der Lattenlegung 9 absetzen kann.The robot 24 - two or more than two robots 24 can also be provided - can be moved on a bridge 25 so that it can pick up stacks 11 of slats 27 and set them down in a desired compartment 10, for example the slat laying 9.
