Description
Verfahren und Vorrichtung zum Teilen von Metallband Method and device for dividing metal strip
Die Erfindung betrifft ein Verfahren zum Teilen von Metallband, mittels einer Schere zur Unterteilung von Metallbändern quer zur Bandlaufrichtung in Band- anlagen, wobei ein Obermesserträger und ein Untermesserträger an einer Seite ein Obermesser und ein Untermesser aufweisen und an der anderen Seite an einer gemeinsamen Drehachse derart gelagert sind und sich das Metallband während des Schneidvorganges im Stillstand befindet. Die Erfindung betrifft weiterhin eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for dividing metal strip, by means of a pair of scissors for dividing metal strips transversely to the strip running direction in belt systems, wherein a top blade carrier and a lower blade carrier on one side of an upper blade and a lower blade and on the other side on a common axis of rotation are stored and the metal strip is during the cutting process at a standstill. The invention further relates to a device for carrying out the method.
Eine gattungsgemäße Schere ist aus DE 103 61 844 A1 bekannt. Bei dieser bekannten Schere führt der Obermesserträger eine zangenförmige Bewegung aus, wobei das Obermesser eine bogenförmige Bewegung zum Untermesser hin ausführt.A generic pair of scissors is known from DE 103 61 844 A1. In this known pair of scissors, the upper knife carrier performs a pincer-like movement, with the upper knife performing an arcuate movement towards the lower knife.
Die auch als IPR -Schere bezeichnete Vorrichtung (Schere mit integriertem Treiber - Integrated Pinch Roll) wird in Bandanlagen sowohl im Einlauf- als auch im Auslaufbereich eingesetzt, um Bandanfang und / oder Bandende abzuschneiden bzw. im Auslauf den Trennschnitt in kontinuierlich laufenden Band- anlagen zu realisieren. Die übliche Schnittfolge und Geometrie der Scherenmesser sieht vor, dass das Band, beispielsweise Stahlband, von oben nach unten getrennt wird. Das obere Messer bewegt sich also am feststehenden unteren Messer vorbei.Also known as IPR scissors (scissors with integrated driver - integrated pinch roll) is used in conveyor systems both in the inlet and in the outlet area to cut off the beginning and / or end of the tape or in the outlet separation in continuously running belt systems to realize. The usual cutting sequence and geometry of the shear blades provides that the band, for example steel band, is separated from top to bottom. The upper knife thus moves past the fixed lower knife.
Bei der bekannten Konfiguration ist ein integrierter Treiber am festen unteren Messerrahmen befestigt, so dass die Pass - Linie des Bandes konstant in der Bandanlage gehalten werden kann. Um einen geeigneten Abstand des Bandes von den Messern bei geöffneter Schere zu gewährleisten, steht das untere Messer ca. 25 bis 35 mm tiefer als die untere Treibrolle und das obere Messer steht ca. 150 bis 175 mm über dem Band, um ein Anschlagen der laufenden
Bandes mit den Messern, während die Bandanlage in Betrieb ist, zu vermeiden. Siehe hierzu Figur 1.In the known configuration, an integrated driver is attached to the fixed lower knife frame, so that the pass line of the tape can be kept constant in the belt system. In order to ensure a suitable distance of the tape from the knives with the scissors open, the lower knife is about 25 to 35 mm lower than the lower drive roller and the upper knife is about 150 to 175 mm above the tape to stop the running Tape with the knives while the strip line is in operation to avoid. See FIG. 1.
Nachteilig bei einer derartigen Schere ist, dass sich der Schneidgrat an der Unterseite des Metallbandes bzw. der Metallbänder befindet und beim Weiter- transport die Transportrollen beschädigt werden könne.The disadvantage of such a pair of scissors is that the cutting burr is located on the underside of the metal strip or the metal strips and the transport rollers could be damaged during further transport.
Der Erfindung liegt daher die Aufgabe zugrunde, die oben genannten Nachteile zu vermeiden.The invention is therefore based on the object to avoid the above-mentioned disadvantages.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einem Verfahren gemäß Oberbegriff von Anspruch 1 das Untermesser eine bogenförmige Bewegung zum feststehenden Obermesser hin ausführt. Durch einen Schnitt von unten (up - cut) wird erreicht, dass der Schneidgrat auf der Oberseite des Metallbandes erzeugt wird. Da aber nur die Unterseite mit den Transportrollen in Kontakt ist und diese keinen Schneidgrat aufweist, werden die Transportrollen geschont und nicht beschädigt.This object is achieved in that in a method according to the preamble of claim 1, the lower blade performs an arcuate movement to the fixed upper blade. A cut from below (up - cut) ensures that the cutting burr is produced on the upper side of the metal strip. But since only the bottom is in contact with the transport rollers and this has no Schneidgrat, the transport rollers are spared and not damaged.
Weitere Ausgestaltungen des Verfahrens ergeben sich aus den diesbezüglichen Unteransprüchen.Further embodiments of the method will become apparent from the relevant subclaims.
Die Erfindung betrifft außerdem eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens.The invention also relates to a device for carrying out the method according to the invention.
Weitere Ausgestaltungen der Vorrichtung ergeben sich aus den diesbezügli- chen Unteransprüchen.Further embodiments of the device will become apparent from the dependent claims.
Der entscheidende Vorteil des erfindungsgemäßen Verfahrens liegt darin, dass der Schnitt von unten nach oben ausgeführt wird und ein Schneidgrat auf der Oberseite des Metallbandes entsteht. Dadurch, dass sich der Schneidgrat auf der Oberseite befindet, werden die nachfolgenden Rollen, auf denen das Metallband transportiert wird, geschont.
Um bei dem erfindungsgemäßen Verfahren einen genügend großen Abstand zum Metallband im Anlagenbetrieb zu gewährleisten wird in Weiterbildung vorgeschlagen, das Metallband aus der Passlinie nach oben anzuheben. Im Gegensatz zum Stand der Technik wird die integrierte untere Treibrolle nicht am feststehenden Messerrahmen befestigt und fixiert so das Band auf seiner festen Passlinie, sondern die untere Treibrolle wird am beweglichen Untermesserträger befestigt. Beim Anheben des Untermesserträgers, beispielsweise mittels eines Hydraulikzylinders, wird die untere Treibrolle daher an das Metallband angelegt und hebt dieses aus der Passlinie auf eine angehobene Passlinie. Das Metallband wird somit von seiner Pass - Linie in der Anlage angehoben und bewegt sich mit dem Untermesser hin zum Schneid- /Trennvorgang.The decisive advantage of the method according to the invention is that the cut is carried out from bottom to top and a cutting burr is formed on top of the metal strip. The fact that the cutting burr is on the top, the subsequent roles on which the metal strip is transported, spared. In order to ensure a sufficiently large distance to the metal strip in plant operation in the process of the invention is proposed in a further development to raise the metal strip from the pass line up. In contrast to the prior art, the integrated lower drive roller is not attached to the fixed blade frame and thus fixes the tape on its tight fitting line, but the lower drive roller is attached to the movable lower blade carrier. When lifting the lower knife carrier, for example by means of a hydraulic cylinder, the lower drive roller is therefore applied to the metal strip and lifts it from the pass line to a raised pass line. The metal strip is thus lifted from its pass line in the system and moves with the lower blade towards the cutting / separating process.
Vorteilhaft ist ferner, wenn die obere Treibrolle mittels einer Aufhängung positioniert wird, an der sich der untere Messerträger mittels des weiter oben er- wähnten Hydraulikzylinders abstützt.It is also advantageous if the upper drive roller is positioned by means of a suspension on which the lower knife carrier is supported by means of the above-mentioned hydraulic cylinder.
