Abstract
Description
Die Erfindung betrifft Vorrichtungen für einen verlust losen Stapelwechsel an Querschneidern in der Papier- und Kartonindustrie.The invention relates to devices for a loss loose stack changes on cross cutters in the paper and Cardboard industry.
Bogenablagen oder obengenannten Art werden in Deutschland z. B. von den Firmen Jagenberg AG in Düsseldorf und Dörries AG in Düren, in Arbeitsbreiten bis etwa 3,5 m her gestellt.Sheet trays or the type mentioned above are made in Germany e.g. B. from the companies Jagenberg AG in Düsseldorf and Dörries AG in Düren, in working widths up to 3.5 m posed.
Sie bestehen im wesentlichen aus folgenden Teilen (Abb. 1):They essentially consist of the following parts ( Fig. 1):
- 1 Transportband, auf dem die Bogen übereinanderliegend, geschuppt, zugeführt werden 1 conveyor belt on which the sheets are fed one above the other, shingled
- 2 angetriebenes Walzenpaar, zum Ausstoß und zur Fixierung der Bogen 2 driven rollers, for ejecting and fixing the sheets
- 3 Anschlagbalken, auf die Bogenlänge einstellbar 3 stop bars, adjustable to the arc length
- 4 Schüttelplatte zur Verbesserung der Stapelqualität 4 shaking plate to improve the stack quality
- 5 Trennbleche zwischen den einzelnen Nuten 5 dividers between the individual grooves
- 6 Stabrost zum Wechseln des vollen Stapels 6 Bar grate for changing the full stack
- 7 Hubtisch 7 lifting table
Die Absenkgeschwindigkeit des Hubtisches wird automatisch so geregelt, daß die Lage der Stapeloberfläche in etwa konstant bleibt.The lowering speed of the lifting table is automatic regulated so that the position of the stack surface approximately remains constant.
Zum Stapelwechsel wird zunächst die volle Palette mit Hilfe einer Lichtschranke bis kurz unterhalb des Stabrostes abgesenkt (h 1 Abb. 1). Damit der Rost störungsfrei heraus gefahren werden kann, muß die Bogenzufuhr für etwa 3 bis 6 Bogen unterbrochen werden. Oberhalb des Rostes entsteht nun ein Speicher, der die nachfolgenden Bogen für den gesamten Stapelwechsel aufnehmen kann. To change the stack, the full pallet is first lowered using a light barrier to just below the bar grate (h 1 Fig. 1). The sheet feed must be interrupted for about 3 to 6 sheets so that the grate can be moved out without problems. A storage is now created above the grate, which can accommodate the subsequent sheets for the entire stack change.
Durch die Ausschußbogen entsteht, besonders bei Karton und Pappe, ein nicht unerheblicher Verlust. Dieser beträgt z. B. bei einer Bogendicke von 0,5 mm (ca. 350 g/m2) und einer Stapelhöhe von 1,25 m etwa 0,12 bis 0,24%. Bei einer Pro duktionsleistung einer modernen Kartonmaschine von ca. 100 000 t/a bedeutet dies einen Verlust zwischen 100 000,-- bis 200 000,-- DM/a. Bei 700 g/m2 liegt er entsprechend doppelt so hoch.The rejects result in a not inconsiderable loss, especially with cardboard and cardboard. This is z. B. with a sheet thickness of 0.5 mm (about 350 g / m 2 ) and a stack height of 1.25 m about 0.12 to 0.24%. With a production output of a modern board machine of approx. 100,000 t / a, this means a loss of between 100,000 to 200,000 DM / a. At 700 g / m 2 , it is correspondingly twice as high.
Der Erfindung liegt nun die Aufgabe zugrunde, den Stapel wechsel ohne Verlust durchzuführen.The object of the invention is now the stack change without loss.
Diese Aufgabe wird nun erfindungsgemäß durch die kennzeich nenden Merkmale der Ansprüche 1 und alternativ 2 und 3 gelöst.This object is now characterized by the nenden features of claims 1 and alternatively 2 and 3 solved.
Kurz oberhalb des Stabrostes (6) wird ein kleiner Hilfsrost (8) mit etwa 6 cm langen Dornen angeordnet. Diese Dorne sind auf einem maschinenbreiten Träger (9) befestigt, der seiner seits mit Pneumatikzylindern (10) schlagartig horizontal be bewegt werden kann. Die Dorne sind auf Lücken zu den Stäben des Hauptrostes angebracht.A small auxiliary grate ( 8 ) with approximately 6 cm long spikes is arranged just above the bar grate ( 6 ). These mandrels are attached to a machine-wide support ( 9 ), which on the other hand can be moved suddenly with pneumatic cylinders ( 10 ) horizontally. The mandrels are attached to gaps to the bars of the main grate.
Zum Stapelwechsel wird wie bisher der Stapel bis kurz unter halb des Hauptrostes abgesenkt. Da die Bogen nun in einem ge wissen Abstand nacheinander auf den Stapel fallen, kann mit einer weiteren Lichtschranke (11) in der Höhe h 2, etwas ober halb des Hilfsrostes, eine Lücke erfaßt werden, in die dann der Hilfsrost hineinschnellt. Die nachfolgenden Bogen legen sich nun einseitig auf die Dorne auf, so daß sich unterhalb der Dorne wiederum eine Lücke bildet, in die dann der Haupt rost einfährt. Wenn der Hauptrost bis zur Endlage herausge fahren ist, wird der Hilfsrost zurückgezogen. Der weitere Ab lauf erfolgt dann wie üblich. To change the stack, the stack is lowered to just below half of the main grate as before. Since the sheets now fall onto the stack one after the other at a known distance, a gap can be detected with a further light barrier ( 11 ) at height h 2 , somewhat above half of the auxiliary grate, into which the auxiliary grate then snaps. The following sheets now lay on one side on the mandrels, so that a gap is formed below the mandrels, into which the main rust then enters. When the main grate has moved out to the end position, the auxiliary grate is withdrawn. The rest of the process then takes place as usual.
Eine andere Möglichkeit eines verlustlosen Stapelwechsels besteht darin, daß die Bogenzufuhr für die Dauer der Rost betätigung unterbrochen wird.Another possibility of a lossless batch change is that the sheet feed for the duration of the rust operation is interrupted.
Hierzu müssen zwei Transportbänder hintereinander ange ordnet und in die Lücke eine Einklemmvorrichtung angebracht werden. Diese besteht aus einem feststehenden Oberteil (12), das etwa oberhalb der Bogenebene angebracht ist und ein be weglicher Balken (13) unterhalb.For this purpose, two conveyor belts must be arranged one behind the other and a clamping device must be attached in the gap. This consists of a fixed upper part ( 12 ), which is attached approximately above the arch plane and a movable bar ( 13 ) below.
Zum Stapelwechsel wird - digital gesteuert - die Bogenlage kurz nach einer Überlappungskante eingeklemmt. Die weiter zulaufenden Bogen stauen sich nun an dem feststehenden Ober teil, während die noch freien Bogen weitertransportiert werden. Auf diese Weise kann die zur Rostbetätigung erforder liche Lücke von 3 bis 5 Bogen erreicht werden.The sheet position is digitally controlled to change the stack pinched shortly after an overlap edge. The further tapering arches now jam on the fixed upper part, while the still free sheets are transported on will. In this way, the grate actuation required gap of 3 to 5 sheets can be reached.
Damit die weiterlaufenden Bogen nicht durch die überhängen den Bogen abgelenkt werden können, wird erfindungsgemäß eine maschinenbreite Leitwalze (14) angebracht, deren Position zur Klemmstelle automatisch der Bogenlänge (l) angepaßt wird. Dadurch werden die ablaufenden Bogen in ihrer Lage fixiert.So that the sheets that continue to run cannot be deflected by the overhanging sheets, a machine-wide guide roller ( 14 ) is attached according to the invention, the position of which at the nip point is automatically adapted to the sheet length (1) . As a result, the running sheets are fixed in their position.
