- the device described is used, for example, in a floor layer, in which at the ends of hose sections floors, such as cross bottoms, are formed. These crossfloor sacks are then transported scaled, the scale flow separated and arranged the sacks into stacks. The stacks are then often stored in a crusher and then palletized.
- the device described can be used for the separation of scale flows, in which the following workpiece rests on the leading workpiece. It is conceivable, however, a scale flow, wherein each of the leading workpiece rests on the respective subsequent workpiece. In this case, when the second conveyor belt is operated at a higher speed, a part of the leading part of the scale flow must be lifted off the first conveyor. The means for lifting must then always be operated at the same speed as the second conveyor.

Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Trennen eines geförderten Stromes von geschuppt übereinander liegenden, flachen Werkstücken gemäß der Oberbegriffe der Patentansprüche 1 und 9.The invention relates to an apparatus and a method for separating a conveyed stream of scaly superimposed, flat workpieces according to the preambles of
Derartige Vorrichtungen sind beispielsweise aus der Offenlegungsschrift
Die beschriebene Vorrichtung ist zur Trennung von Schuppenströmen verwendbar, bei denen das nachfolgende Werkstück auf dem vorauslaufenden Werkstück aufliegt. Denkbar ist jedoch ein Schuppenstrom, bei dem jeweils das vorauslaufende Werkstück auf dem jeweils nachfolgenden Werkstück aufliegt. In diesem Fall müssen, wenn das zweite Förderband mit höherer Geschwindigkeit betrieben wird, ein Teil des vorauslaufenden Teils des Schuppenstromes vom ersten Fördermittel abgehoben werden. Die Mittel zum Anheben müssen dann immer mit gleicher Geschwindigkeit wie das zweite Fördermittel betrieben werden.The device described can be used for the separation of scale flows, in which the following workpiece rests on the leading workpiece. It is conceivable, however, a scale flow, wherein each of the leading workpiece rests on the respective subsequent workpiece. In this case, when the second conveyor belt is operated at a higher speed, a part of the leading part of the scale flow must be lifted off the first conveyor. The means for lifting must then always be operated at the same speed as the second conveyor.
Bei dem Betrieb einer beschriebenen Vorrichtung hat sich gezeigt, dass, insbesondere bei größeren Formaten der Werkstücke, Werkstücke in dem abgehobenen Teil des Schuppenstroms nicht vollständig vom Fördermittel abgehoben werden, sondern durch, beispielsweise aufgrund der Schwerkraft, auftretenden Biegungen oder Krümmungen zum Teil weiterhin mit dem Förderband in Kontakt stehen. Da während des Trennvorganges der abgehobene Teil des Schuppenstromes mit einer anderen Geschwindigkeit als das darunter befindliche Fördermittel angetrieben wird, kann es zu Beschädigungen der Werkstücke und/oder zu einer Deformation des Schuppenstromes kommen.In the operation of a described device has been shown that, especially in larger formats of the workpieces, workpieces are not completely lifted in the raised part of the scale flow from the conveyor, but by, for example, due to gravity, occurring bends or bends in part continue to be in contact with the conveyor belt. Since during the separation process, the lifted portion of the scale flow is driven at a different speed than the conveyor located below, it can cause damage to the workpieces and / or to a deformation of the scale flow.
Die Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zu schaffen, in der ein Schuppenstrom sicher und ohne Beschädigung der Werkstücke trennbar ist.The object of the present invention is therefore to provide a device in which a scale flow can be separated safely and without damaging the workpieces.
Die Aufgabe wird gelöst durch eine Vorrichtung, die die Merkmale des kennzeichnenden Teils des Anspruchs 1 umfasst.The object is achieved by a device comprising the features of the characterizing part of claim 1.
Demnach sind weitere Mittel zum Abheben von Werkstücken von zumindest einem der Fördermittel vorgesehen, welche auf zumindest ein Werkstück in einem zur Trennstelle beabstandeten Bereich des Schuppenstromes wirken. Diese weiteren Mittel zum Abheben können dabei auf dasselbe Werkstück wirken, auf welches bereits die ersten Mittel zum Abheben wirken. Die weiteren Mittel können aber auch ein dem der Trennstelle benachbarten Werkstück folgenden Werkstück erfassen. Mit diesen weiteren Mitteln zum Abheben von Werkstücken wird vermieden, dass Werkstücke zumindest teilweise das darunter angeordnete Fördermittel berühren.Accordingly, further means for lifting workpieces are provided by at least one of the conveying means, which act on at least one workpiece in a spaced apart from the separation point region of the scale flow. These further means for lifting can act on the same workpiece, which already act on the first means for lifting. However, the further means can also detect a workpiece adjacent to the workpiece adjacent to the separation point. With these further means for lifting workpieces is avoided that workpieces at least partially touch the conveyor disposed thereunder.
In einer vorteilhaften Ausgestaltung ist der Zeitraum, während dem die ersten Mittel zum Abheben von Werkstücken auf dieses Werkstück wirken und der Zeitraum, während dem die weiteren Mittel zu Abheben von Werkstücken auf zumindest ein Werkstück wirkt, gleichzeitig beginnen oder gleichzeitig enden. Auf diese Weise ist bei einem Schuppenstrom, in dem das nachfolgende Werkstück auf dem vorauslaufenden Werkstück aufliegt, sichergestellt, dass nach einem Zeitraum, in dem die beiden Fördermittel mit unterschiedlichen Geschwindigkeiten betrieben werden, der zuvor abgehobene Teil des Schuppenstromes derart in Kontakt mit dem Fördermittel gebracht wird, dass alle Werkstücke gleichzeitig wieder das Fördermittel berühren. Bei einem Schuppenstrom, in dem das vorauslaufende Werkstück auf dem nachfolgenden Werkstück aufliegt, ist analog sichergestellt, dass alle Werkstücke gleichzeitig und gleichmäßig vom Fördermittel abgehoben werden. Die ersten und die weiteren Mittel zum Anheben von Werkstücken können relativ zum Maschinengestell feststehen. Es können sich aber auch zumindest Bestandteile der Mittel zum Anheben von Werkstücken relativ zum Maschinengestell bewegen.In an advantageous embodiment, the period during which the first means for lifting workpieces act on this workpiece and the period during which the further means for lifting workpieces acts on at least one workpiece, start simultaneously or end simultaneously. In this way, in a shingled stream, in which the following workpiece rests on the leading workpiece, it is ensured that after a period in which the two conveying means are operated at different speeds, the previously lifted part of the scale flow is brought into contact with the conveying means that all workpieces touch the conveyor again at the same time. At a Scrap flow, in which the leading workpiece rests on the subsequent workpiece, is analogously ensured that all workpieces are lifted simultaneously and evenly from the conveyor. The first and the further means for lifting workpieces can be fixed relative to the machine frame. However, at least components of the means for lifting workpieces can also move relative to the machine frame.
In vorteilhafter Ausgestaltung der Erfindung umfassen die weiteren Mittel zum Anheben von Werkstücken Nocken. Zum Zwecke des Anhebens überragen diese Nocken zumindest zeitweise die Ebene zumindest eines Transportmittels, auf welcher die Werkstücke während des Transports aufliegen. So können beispielsweise zwei Nocken vorgesehen sein, die Werkstücke im Bereich ihrer Außenbereiche erfassen. Auch weitere Nocken können denkbar sein, um ein Durchbiegen des Werkstückes in seinem Mittenbereich zu vermeiden.In an advantageous embodiment of the invention, the further means for lifting workpieces comprise cams. For the purpose of lifting these cams protrude at least temporarily over the plane of at least one means of transport, on which the workpieces rest during transport. For example, two cams can be provided which detect workpieces in the area of their outer areas. Also, further cams may be conceivable in order to avoid bending of the workpiece in its central region.
Besonders vorteilhaft ist es, die Nocken der weiteren Mittel zum Anheben von Werkstücken auf oder an umlaufenden Transportmitteln anzuordnen. Die Länge des oder der Transportmittel ist dabei so auszulegen, dass Nocken im Maschinentakt auf die Werkstücke wirken.It is particularly advantageous to arrange the cams of the further means for lifting workpieces on or on circulating transport means. The length of the transport or the means of transport is designed so that cams act on the workpieces in the machine cycle.
Auch die ersten Mittel zum Anheben des der Trennstelle benachbarten Werkstücks können auf oder an umlaufenden Transportmitteln angeordnete Nocken aufweisen. Dabei können alle Nocken tragenden Transportmittel jeweils über ein erstes Umlenkmittel laufen, welche gleiche Geschwindigkeiten aufweisen. Diese jeweils ersten Umlenkmittel können angetrieben sein. Auf diese Weise wirken alle Nocken in gleichbleibender Phasenlage auf die Werkstücke. Umlenkmittel können dabei Zahnräder oder Riemenscheiben sein. Selbstverständlich kann auch ein einziges Umlenkmittel, etwa eine Welle, vorgesehen sein, über welche die Transportmittel laufen.The first means for lifting the workpiece adjacent to the separation point may also have cams arranged on or on peripheral transport means. In this case, all cam-carrying transport can each run over a first deflection, which have the same speeds. These respective first deflection means can be driven. In this way, all cams act in constant phase on the workpieces. Deflection means may be gears or pulleys. Of course, a single deflection means, such as a shaft, may be provided, over which the means of transport run.
In weiterer Ausgestaltung der Erfindung laufen die Transportmittel des weiteren Mittels zum Anheben von Werkstücken über weitere Umlenkmittel, wobei die Lage dieser weiteren Umlenkmittel relativ zum ersten Umlenkmittel veränderbar ist. Diese relative Lageänderung kann dabei parallel zu der Ebene der Fördermittel liegen, auf welcher die Werkstücke während des Transportes aufliegen. Die Lageänderung der Umlenkmittel führt zu einer Veränderung des Zeitraumes, während dem die Nocken auf die Werkstücke wirken. Somit kann der Zeitpunkt, zu dem die Werkstücke des der Trennstelle nachfolgenden Teils des Schuppenstromes nach dem Trennvorgang wieder in Kontakt mit den Fördermittel treten, verändert werden.In a further embodiment of the invention, the transport means of the further means for lifting workpieces run over further deflection means, wherein the position of this further deflection means relative to the first deflection means changeable is. This relative change in position may be parallel to the plane of the conveyor on which rest the workpieces during transport. The change in position of the deflection leads to a change in the period during which the cams act on the workpieces. Thus, the time at which the workpieces of the separation point subsequent part of the scale flow after the separation process again come into contact with the funding can be changed.
Vorteilhaft ist es, wenn zusätzlich die Position des oder der Nocken auf oder an dem Transportmittel veränderbar ist. Durch diese Maßnahme können die Mittel zum Anheben an die Formate der Werkstücke angepasst werden. Dies ist insbesondere dann von Vorteil, wenn die Vorrichtung im Zusammenhang mit einer Herstellungsmaschine wie etwa Bodenlegern, betrieben wird, auf oder mit welcher Werkstücke verschiedener Formate produziert werden können. Im Zusammenhang mit der Lageänderung der Umlenkmittel dient die Veränderung der Position des oder der Nocken dazu, dass die Nocken des ersten Mittels zum Anheben und die Nocken des weiteren Mittels zum Anheben gleichzeitig mit den Werkstücken in Kontakt treten oder gleichzeitig diesen Kontakt beenden.It is advantageous if in addition the position of the cam or on or on the transport means is variable. By this measure, the means for lifting the formats of the workpieces can be adjusted. This is particularly advantageous when the device is operated in conjunction with a manufacturing machine such as floor levelers, on or with which workpieces of various formats can be produced. In connection with the change in position of the deflection means, the change in the position of the cam or cams causes the cams of the first lifting means and the cams of the further lifting means to simultaneously contact the workpieces or simultaneously terminate this contact.
In weiterer Ausgestaltung der Erfindung ist zumindest eine Gegenlage vorgesehen, gegen welche die Werkstücke durch die ersten und/oder weiteren Mittel zum Abheben von Werkstücken von einem Fördermittel andrückbar sind.In a further embodiment of the invention, at least one counter-bearing is provided, against which the workpieces can be pressed by the first and / or further means for lifting workpieces from a conveyor.

Das zweite Förderband 3 kann im Vergleich zum Förderband 2 mit gleicher oder höherer Geschwindigkeit angetrieben werden. Die Transportketten 9, 10 werden immer mit im Vergleich zum Förderband 2 gleicher Geschwindigkeit angetrieben. Der mit der Transportkette 10 umlaufende Nocken 12 überragt nach dem Passieren der Umlenkrolle 8 das obere Trum des Förderbandes 3 und hebt so ein Werkstück 7' und damit auch folgende Werkstücke 7 von dem Förderband 3 ab. In diesem Moment wird die Fördergeschwindigkeit des Förderbandes 3 erhöht, so dass der dem Werkstück 7' voranlaufende Teil des Schuppenstromes von den angehobenen Werkstücken 7' getrennt wird. Um zu vermeiden, dass die dem angehobenen Werkstück 7' folgenden Werkstücke 7 mit dem Förderband 3 in Kontakt kommen, passiert nach kurzer Zeit auch der Nocken 11 die Umlenkrolle 8 und hebt Werkstücke 7 von dem Förderband 3. Diese Situation während des Trennvorgangs ist in
Die Vorrichtung 1 umfasst weiterhin einen am nicht dargestellten Maschinengestell angebrachten Rahmen 16, an dem zwei Lenker 17, 18 schwenkbar angeordnet sind. Die Lenker 17, 18 sind mit einer Koppelstange 19 verbunden. Die Koppelstange 19 trägt zwei Umlenkrollen 20, 21, über welche ein Band 22 umläuft. Dieses Band 22 liegt aufgrund der Gewichtskraft der Lenker 17, 18, der Koppelstange 19 und der Umlenkrollen 20, 21 auf den Werkstücken 7 auf und drückt diese gegen die Nocken 11, 12. Das Band 22 wird dabei nur von den Werkstücken 7, 7', die im angehobenen Zustand im wesentlichen von den Nocken 11 und 12 gefördert werden, bewegt. Die Elemente 17 bis 22 bilden somit eine Gegenlage zu den Nocken 11 und 12, so dass die Werkstücke 7 klemmend festgehalten werden.The device 1 further comprises a
