Definitions
- the invention relates to a method for processing edges of plate-shaped workpieces, according to the preamble of claim 1. Such a method is from the document DE 20 2009 006 536 U1 known.
- plate-shaped workpieces are used in particular in the furniture industry.
- wood-based materials but also wood-containing materials, such as chipboard, are processed, whereby plate-shaped intermediate products, which are usually already coated on their flat sides, are first cut to the format desired for further processing and then processed in the area of their narrow sides, including in particular the provision of suitable coatings on the narrow sides referred to below as edges is to be understood.
- This processing of the edges of the plate-shaped workpieces cut to the desired format often takes place in so-called edge circles.
- the workpieces are fed individually to the conveying circuit, conveyed in the circuit until the processing of all edges of the respective workpiece to be machined has been completed and then removed from the conveying circuit again.
- a disadvantage of known conveyor circuits is that the individual processing units for edge processing along the conveyor circuit and conveyor devices, which are part of the conveyor circuit, can process or convey plate-shaped workpieces with different dimensions at different speeds.
- the adjustment of the individual components of such a device to an optimal throughput is only possible to a limited extent, since plates of different dimensions are to be processed regularly in such devices.
- the invention is therefore based on the object of demonstrating a device and a method for processing edges of plate-shaped workpieces, which enables uniform utilization of all individual elements of the device and thus optimal utilization of the entire device.
- the method according to the invention provides for the dimensions of the workpieces to be fed into the conveying circuit before they are fed Detect and determine the order in which the workpieces are fed into the conveyor circuit, depending on the dimensions of the workpieces recorded.
- the device according to the invention has a loading device which is set up to determine the sequence in which the workpieces are fed into the conveying circuit as a function of the dimensions of the workpieces.
- one element of the conveyor circuit works in such a way that a certain number of pieces can be processed per unit of time and another element of the conveyor circuit in such a way that a certain running distance of edge length per unit of time can be processed
- the workpieces are put together in such a way that workpieces with short ones to be processed follow edges on workpieces with long edges to be machined and vice versa.
- the device which can handle a certain number of workpieces per unit of time is not used properly because workpieces with long edges jam in front of the device which can process a certain edge length per unit of time.
- the conveyor circuit is advantageously designed in such a way that in each case one edge of a workpiece is machined when it is conveyed along a processing section, that is to say a section of the section of the conveyor circuit in which the edge is processed by a processing unit.
- a processing section that is to say a section of the section of the conveyor circuit in which the edge is processed by a processing unit.
- each will Conveying a certain number of workpieces along the processing section achieves an average uniform ratio between the edge length to be machined and the number of pieces, which would not be the case if the long edges of all workpieces were processed first and then the short edges of the individual workpieces were processed in a further cycle of the conveyor circuit , This would have the consequence that the ratio of the edge length to be machined to the number of workpieces would change significantly between the two runs of the conveyor circuit, which in turn would overload the capacities of individual units while at the same time reducing the utilization of other units.
- a group feed into the feeder feeder circuit is done, for example, by a.
- the group feeding is carried out in particular using a sorting station in which the workpieces are initially grouped together in such a way that the dimensions relevant to the capacities in the conveyor circuit are as constant as possible on average for the respective group, i.e. that the compilation is carried out in such a way that a fluctuation in the dimensions of group means to group means is minimized, for example avoiding assembling a group from very small workpieces, that is to say workpieces with a large ratio of the number of pieces to the edge length to be machined.
- the Figure 1 shows a schematic representation of an exemplary device according to the invention.
- the funding cycle 1 is composed of two oppositely working conveyors 8 and 9 and two translators 12 and 13, which workpieces can transfer from one conveyor to the other.

- the conveying circuit also has means (not shown) for changing the orientation of the workpieces between their passes through the machining path 2, it is possible to design the machining path 2 such that only one edge 4 of the workpiece is machined per conveyance of a workpiece through the machining path , The workpiece then passes through the translator 12, the second conveyor 9 and the translator 13, whereupon it again arrives at the conveyor 8 and is conveyed through the processing line again. If the orientation of the workpiece between the conveyors along the processing section 2 is changed, another edge 4 of the respective workpiece 3 is machined.
- the means for changing the orientation of the workpieces 3 can in principle be located at any position in the conveyor circuit.
- a removal station (not shown) can be provided, which can basically be located at any point in the conveyor circuit 1.
- the conveyor 9 is designed in such a way that it can further convey the workpieces 3 beyond the transfer point with the translator 13, so that a section of the conveyor 9 no longer belongs to the conveyor circuit 1, but rather a removal section 14 represents from which the workpieces can be removed.
- the loading device has a loading station 6 and a sorting station 7.
- the workpieces are put together in groups according to their dimensions, in the example shown there are groups of four workpieces each, which are put together in a rectangular grid into so-called pictures by the loading station 6 and fed in groups to the conveyor circuit 1.

Description
Die Erfindung betrifft ein Verfahren zur Bearbeitung von Kanten plattenförmiger Werkstücke, gemäß dem Oberbegriff des Anspruchs 1. Ein solches Verfahren ist aus dem Dokument
Derartige plattenförmige Werkstücke kommen insbesondere in der Möbelindustrie zum Einsatz. Dort werden insbesondere Holzwerkstoffe aber auch holzhaltige Werkstoffe, wie beispielsweise Spanplatten verarbeitet, wobei plattenförmige Zwischenprodukte, welche an ihren flächigen Seiten in der Regel bereits fertig beschichtet sind, zunächst auf das für die Weiterverarbeitung gewünschte Format geschnitten und dann im Bereich ihrer Schmalseiten bearbeitet werden, worunter insbesondere das Versehen der im Folgenden als Kanten bezeichneten Schmalseiten mit geeigneten Beschichtungen zu verstehen ist.Such plate-shaped workpieces are used in particular in the furniture industry. There, in particular wood-based materials but also wood-containing materials, such as chipboard, are processed, whereby plate-shaped intermediate products, which are usually already coated on their flat sides, are first cut to the format desired for further processing and then processed in the area of their narrow sides, including in particular the provision of suitable coatings on the narrow sides referred to below as edges is to be understood.
Diese Bearbeitung der Kanten der auf das gewünschte Format zurechtgeschnittenen plattenförmigen Werkstücke findet dabei häufig in sogenannten Kantenkreisen statt. Hierunter sind Vorrichtungen zu verstehen, welche einen Förderkreislauf umfassen, in welchem die Werkstücke mehrfach zur Kantenbearbeitung entlang einer Bearbeitungsstrecke förderbar sind. Gemäß dem Stand der Technik werden die Werkstücke einzeln dem Förderkreislauf zugeführt, in diesem solange im Kreislauf gefördert, bis die Bearbeitung sämtlicher zu bearbeitender Kanten des jeweiligen Werkstücks abgeschlossen ist und dann aus dem Förderkreislauf wieder ausgeschleust.This processing of the edges of the plate-shaped workpieces cut to the desired format often takes place in so-called edge circles. This includes devices which include a conveyor circuit in which the workpieces can be conveyed multiple times for edge processing along a processing line. According to the prior art, the workpieces are fed individually to the conveying circuit, conveyed in the circuit until the processing of all edges of the respective workpiece to be machined has been completed and then removed from the conveying circuit again.
Nachteilig an bekannten Förderkreisläufen ist jedoch, dass die einzelnen Bearbeitungsaggregate zur Kantenbearbeitung entlang des Förderkreislaufs sowie Fördereinrichtungen, die Bestandteil des Förderkreislaufs sind, plattenförmige Werkstücke mit unterschiedlichen Abmessungen in unterschiedlicher Geschwindigkeit bearbeiten bzw. fördern können. Dabei ist die Abstimmung der einzelnen Komponenten einer derartigen Vorrichtung auf einen optimalen Durchsatz nur eingeschränkt möglich, da in derartigen Vorrichtungen regelmäßig Platten verschiedener Abmessungen bearbeitet werden sollen. D.h. werden die einzelnen Aggregate darauf abgestimmt, Platten einer bestimmten Abmessung derart verarbeiten zu können, dass die Kapazitäten derart aufeinander abgestimmt sind, dass es im Förderkreislauf an keiner Stelle zu einem Engpass bzw. Stau kommt, so trifft diese Abstimmung nicht mehr zu, wenn Werkstücke mit anderen Maßen verarbeitet werden sollen, d.h. es kommt dann, beispielsweise vor einem Bearbeitungsaggregat, zu einem Stau, weil dieses Bearbeitungsaggregat die Werkstücke mit den neuen Abmessungen nicht mehr in der Geschwindigkeit verarbeiten kann wie die Werkstücke mit den alten Abmessungen, die weiteren Bestandteile des Förderkreislaufs jedoch weiterhin die alte Bearbeitungskapazität erreichen.A disadvantage of known conveyor circuits, however, is that the individual processing units for edge processing along the conveyor circuit and conveyor devices, which are part of the conveyor circuit, can process or convey plate-shaped workpieces with different dimensions at different speeds. The adjustment of the individual components of such a device to an optimal throughput is only possible to a limited extent, since plates of different dimensions are to be processed regularly in such devices. This means that if the individual units are adapted to be able to process plates of a certain dimension in such a way that the capacities are coordinated with one another in such a way that there is no bottleneck or jam in the conveyor circuit, this coordination no longer applies if workpieces are to be processed with other dimensions, ie there is a jam, for example in front of a processing unit, because this processing unit can no longer process the workpieces with the new dimensions at the same speed as the workpieces with the old dimensions, the other components of the conveyor circuit however, continue to reach the old processing capacity.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zur Bearbeitung von Kanten plattenförmiger Werkstücke aufzuzeigen, welches eine gleichmäßige Auslastung aller einzelnen Elementen der Vorrichtung und damit eine optimale Auslastung der gesamten Vorrichtung ermöglicht.The invention is therefore based on the object of demonstrating a device and a method for processing edges of plate-shaped workpieces, which enables uniform utilization of all individual elements of the device and thus optimal utilization of the entire device.
Die Aufgabe wird gelöst durch ein Verfahren gemäß dem unabhängigen Anspruch 1.The object is achieved by a method according to independent claim 1.
Das erfindungsgemäße Verfahren sieht vor, die Maße der Werkstücke vor deren Zuführung in den Förderkreislauf zu erfassen und die Reihenfolge, in der die Werkstücke dem Förderkreislauf zugeführt werden, in Abhängigkeit von den erfassten Maßen der Werkstücke festzulegen. Die erfindungsgemäße Vorrichtung weist hierfür eine Beschickungsvorrichtung auf, die dazu eingerichtet ist, die Reihenfolge, mit der die Werkstücke dem Förderkreislauf zugeführt werden, in Abhängigkeit von den Maßen der Werkstücke festzulegen.The method according to the invention provides for the dimensions of the workpieces to be fed into the conveying circuit before they are fed Detect and determine the order in which the workpieces are fed into the conveyor circuit, depending on the dimensions of the workpieces recorded. For this purpose, the device according to the invention has a loading device which is set up to determine the sequence in which the workpieces are fed into the conveying circuit as a function of the dimensions of the workpieces.
Durch die Festlegung der Zuführreihenfolge in Abhängigkeit der Maße der Werkstücke ist es möglich, die Beschickungsreihenfolge des Förderkreislaufs so zu wählen, dass eine gleichmäßige Auslastung aller Elemente des Förderkreislaufs und aller an diesem Förderkreislauf vorgesehenen Bearbeitungsvorrichtungen erfolgt.By specifying the feed sequence depending on the dimensions of the workpieces, it is possible to select the loading sequence of the conveyor circuit so that all elements of the conveyor circuit and all processing devices provided on this conveyor circuit are evenly utilized.
Arbeitet beispielsweise ein Element des Förderkreislaufs derart, dass eine bestimmte Stückzahl pro Zeiteinheit bearbeitet werden kann und ein anderes Element des Förderkreislaufs so, dass eine bestimmte laufende Strecke Kantenlänge pro Zeiteinheit bearbeitet werden kann, so werden die Werkstücke derart zusammengestellt, dass Werkstücke mit kurzen zu bearbeitenden Kanten auf Werkstücke mit langen zu bearbeitenden Kanten folgen und umgekehrt. Auf diese Weise wird verhindert, dass jene Einrichtung, die eine bestimmte Anzahl Werkstücke pro Zeiteinheit bewältigen kann, nicht richtig ausgelastet wird, weil sich Werkstücke mit langen Kanten vor der Einrichtung, welche eine bestimmte Kantenlänge pro Zeiteinheit bearbeiten kann, stauen. Umgekehrt wird verhindert, dass, wenn Werkstücke mit kurzen Kanten in großer Anzahl direkt aufeinanderfolgen, eine mangelnde Auslastung der Einrichtung erfolgt, welche eine bestimmte Kantenlänge pro Zeiteinheit bearbeiten kann, während sich Werkstücke vor einer Einrichtung, welche eine gewisse Stückzahl Werkstücke pro Zeiteinheit bewältigen kann, stauen.For example, if one element of the conveyor circuit works in such a way that a certain number of pieces can be processed per unit of time and another element of the conveyor circuit in such a way that a certain running distance of edge length per unit of time can be processed, the workpieces are put together in such a way that workpieces with short ones to be processed Follow edges on workpieces with long edges to be machined and vice versa. In this way it is prevented that the device which can handle a certain number of workpieces per unit of time is not used properly because workpieces with long edges jam in front of the device which can process a certain edge length per unit of time. Conversely, it is prevented that if workpieces with short edges follow one another directly in large numbers, there is insufficient utilization of the facility, which can process a certain edge length per unit of time, while workpieces are in front of a facility, which can handle a certain number of workpieces per unit of time.
Neben den Längen der Kanten können auch weitere Maße, so beispielsweise die Dicken der Werkstücke oder deren Fläche berücksichtigt werden.In addition to the lengths of the edges, other dimensions, such as the thickness of the workpieces or their area, can also be taken into account.
Vorteilhafterweise ist der Förderkreislauf derart ausgebildet, dass jeweils eine Kante eines Werkstücks bearbeitet wird, wenn dieses entlang einer Bearbeitungsstrecke, also einem Streckenabschnitt des Förderkreislaufs, in dem eine Bearbeitung der Kante durch ein Bearbeitungsaggregat erfolgt, gefördert wird. Um die Bearbeitung aller Werkstückkanten zu ermöglichen, ohne jedoch einer der Zahl der Kanten des Werkstückes entsprechenden Anzahl Bearbeitungsstrecken in einem Förderkreislauf zu bedürfen, ist es sinnvoll, die Orientierung des Werkstücks relativ zur Bearbeitungsstrecke zwischen zwei Förderungen des Werkstücks entlang dieser Bearbeitungsstrecke zu ändern. Auf diese Weise kommen die Bearbeitungsaggregate bei jedem Förderdurchgang an einer anderen Kante des Werkstücks zum Eingriff.The conveyor circuit is advantageously designed in such a way that in each case one edge of a workpiece is machined when it is conveyed along a processing section, that is to say a section of the section of the conveyor circuit in which the edge is processed by a processing unit. In order to enable the machining of all workpiece edges without, however, requiring a number of machining sections in a conveyor circuit that corresponds to the number of edges of the workpiece, it makes sense to change the orientation of the workpiece relative to the machining section between two conveyors of the workpiece along this machining section. In this way, the processing units come into engagement on a different edge of the workpiece with each conveying pass.
Dabei ist es möglich, auch die Orientierung der Werkstücke während der Beschickung zu berücksichtigen, d.h. die Werkstücke bereits in einer Orientierung dem Förderkreislauf zuzuführen, welche die unterschiedlichen Bearbeitungskapazitäten berücksichtigt. Dies ist z.B. dann sinnvoll, wenn langgestreckte Werkstücke mit jeweils einem Paar langer und einem Paar kurzer Kanten bearbeitet werden sollen. Werden diese dem Förderkreislauf so zugeführt, dass sich jeweils eine der längeren Kanten eines Werkstücks mit einer der kürzeren Kanten des folgenden Werkstücks und umgekehrt abwechselt, so wird bei jeder Förderung einer gewissen Anzahl Werkstücke entlang der Bearbeitungsstrecke ein im Mittel gleichmäßiges Verhältnis zwischen zu bearbeitender Kantenlänge und Stückzahl erreicht, was nicht der Fall wäre, würden zunächst die langen Kanten sämtlicher Werkstücke und dann in einem weiteren Durchlauf des Förderkreislaufs die jeweils kurzen Kanten der einzelnen Werkstücke bearbeitet. Dies hätte zur Folge, dass sich zwischen den beiden Durchläufen des Förderkreislaufs das Verhältnis der zu bearbeitenden Kantenlänge zur Stückzahl der Werkstücke deutlich ändern würde, wodurch es wiederum zur Überlastung der Kapazitäten einzelner Aggregate bei gleichzeitiger Minderauslastung anderer Aggregate kommen würde.It is also possible to take into account the orientation of the workpieces during loading, that is, to feed the workpieces to the conveyor circuit in one orientation, which takes into account the different machining capacities. This is useful, for example, when elongated workpieces with one pair of long and one pair of short edges are to be processed. If these are fed into the conveying circuit in such a way that one of the longer edges of a workpiece alternates with one of the shorter edges of the following workpiece and vice versa, each will Conveying a certain number of workpieces along the processing section achieves an average uniform ratio between the edge length to be machined and the number of pieces, which would not be the case if the long edges of all workpieces were processed first and then the short edges of the individual workpieces were processed in a further cycle of the conveyor circuit , This would have the consequence that the ratio of the edge length to be machined to the number of workpieces would change significantly between the two runs of the conveyor circuit, which in turn would overload the capacities of individual units while at the same time reducing the utilization of other units.
Eine gruppenweise Zuführung in den Förderkreislauf Beschickungsvorrichtung geschieht beispielsweise durch eine. Die gruppenweise Zuführung erfolgt insbesondere unter der Verwendung einer Sortierstation, in der die Werkstücke zunächst gruppenweise so zusammengestellt werden, dass die für die Kapazitäten im Förderkreislauf relevanten Maße im Mittel der jeweiligen Gruppe nach Möglichkeit konstant sind, d.h. dass die Zusammenstellung derart erfolgt, dass eine Schwankung der Maße von Gruppenmittel zu Gruppenmittel minimiert wird, also beispielsweise vermieden wird, eine Gruppe nur aus sehr kleinen Werkstücken, also Werkstücken mit einem großen Verhältnis von Stückzahl zu zu bearbeitender Kantenlänge zusammenzustellen.A group feed into the feeder feeder circuit is done, for example, by a. The group feeding is carried out in particular using a sorting station in which the workpieces are initially grouped together in such a way that the dimensions relevant to the capacities in the conveyor circuit are as constant as possible on average for the respective group, i.e. that the compilation is carried out in such a way that a fluctuation in the dimensions of group means to group means is minimized, for example avoiding assembling a group from very small workpieces, that is to say workpieces with a large ratio of the number of pieces to the edge length to be machined.
Die
Der Förderkreislauf 1 setzt sich zusammen aus zwei gegenläufig arbeitenden Förderern 8 und 9 sowie zwei Übersetzern 12 und 13, welche Werkstücke von einem auf den anderen Förderer übersetzen können. Der Förderer 8 läuft dabei entlang einer nicht dargestellten Bearbeitungsmaschine, d.h. ein Teilabschnitt des Förderers 8 bildet die Bearbeitungsstrecke 2.The funding cycle 1 is composed of two oppositely working
Weist der Förderkreislauf weiterhin nicht dargestellte Mittel zur Veränderung der Orientierung der Werkstücke zwischen deren Durchläufen durch die Bearbeitungsstrecke 2 auf, so ist es möglich, die Bearbeitungsstrecke 2 so zu gestalten, dass pro Förderung eines Werkstücks durch die Bearbeitungsstrecke nur eine Kante 4 des Werkstücks bearbeitet wird. Daraufhin durchläuft das Werkstück den Übersetzer 12, den zweiten Förderer 9 und den Übersetzer 13, woraufhin es wieder auf den Förderer 8 gelangt und ein weiteres Mal durch die Bearbeitungsstrecke gefördert wird. Wird dabei die Orientierung des Werkstücks zwischen den Förderungen entlang der Bearbeitungsstrecke 2 geändert, so erfolgt die Bearbeitung einer anderen Kante 4 des jeweiligen Werkstücks 3. Dabei können sich die Mittel zur Änderung der Orientierung der Werkstücke 3 grundsätzlich an jeder Position des Förderkreislaufs befinden.If the conveying circuit also has means (not shown) for changing the orientation of the workpieces between their passes through the machining path 2, it is possible to design the machining path 2 such that only one edge 4 of the workpiece is machined per conveyance of a workpiece through the machining path , The workpiece then passes through the
Sind alle zu bearbeitenden Kanten 4 des jeweiligen Werkstücks 3 nach einer entsprechenden Anzahl Durchläufen durch den Förderkreislauf 1 bearbeitet, so werden die Werkstücke 3 dem Förderkreislauf 1 entnommen. Hierzu kann eine nicht dargestellte Entnahmestation vorgesehen sein, die sich grundsätzlich an jeder Stelle des Förderkreislaufs 1 befinden kann. Im gezeigten Beispiel ist der Förderer 9 so gestaltet, dass er die Werkstücke 3 über den Übergabepunkt mit dem Übersetzer 13 hinaus weiter fördern kann, so dass ein Abschnitt des Förderers 9 nicht mehr zum Förderkreislauf 1 gehört, sondern einen Entnahmeabschnitt 14 darstellt, von dem die Werkstücke entnommen werden können.If all edges 4 to be machined of the
Die Beschickungsvorrichtung weist eine Beschickungsstation 6 und eine Sortierstation 7 auf. In der Sortierstation werden die Werkstücke entsprechend ihrer Maße gruppenweise zusammengestellt, im gezeigten Beispiel handelt es sich um Gruppen von jeweils vier Werkstücken, die in einem rechteckigen Raster zu sogenannten Bildern zusammengestellt durch die Beschickungsstation 6 gruppenweise dem Förderkreislauf 1 zugeführt werden.The loading device has a loading station 6 and a
Im Förderkreislauf gelangen sie zunächst in die Vereinzelungsstation 11, welche die in Gruppen zugeführten Werkstücke 3 vereinzelt, bevor diese einzeln durch den Förderer 8 entlang der Förderstrecke 2 gefördert und bearbeitet werden. An den Förderer 8 schließt sich eine Sammelstation 10 an, in welcher die vereinzelten Werkstücke 3 wieder zu Gruppen gruppiert werden. Diese Gruppen werden dann an den Übersetzer 12 übergeben, durch den Förderer 9 zurück gefördert und durch den Übersetzer 13 wieder der Vereinzelungsstation 11 zugeführt.In the conveying circuit, they first reach the
