Description

Die Erfindung bezieht sich auf eine Andrück- und Trennvorrichtung für ein an eine insbesondere als Wendehaspel ausgebildeten Aufwickelhaspel anzuschließendes Metallband, bei der auf der der Aufwickelhaspel gegenüberliegenden Seite des Metallbandes eine gegen das Metallband auf die mit einem Anheftmittel für das Metallband versehende Aufwickelhaspel zu bewegbare Baueinheit aus einem Andrückmittel und einem ihm in Bandlaufrichtung nachgeordneten Messer angeordnet ist.The invention relates to a pressing and separating device for a metal strip to be connected to a take-up reel, in particular a reversing reel a pressing means and a knife arranged downstream of it in the tape running direction.

Beim Aufwickeln von Metallbändern besteht eine Schwierigkeit darin, ohne Unterbrechung des Transportes des Metallbandes das Band an eine Aufwickelhaspel anzuschließen. Der Anschluß eines Bandes bei laufendem Transport besteht sowohl zu Wickelbeginn, wenn mit einem verlorenen Bandanfang gearbeitet wird, als auch während des Wickelns, wenn bei einer Wendehaspel das Wickeln von der einen Aufwickelhaspel auf die andere Aufwickelhaspel übergewechselt werden soll.One problem with winding metal strips is to connect the strip to a take-up reel without interrupting the transport of the metal strip. The connection of a tape during ongoing transport exists both at the start of winding when working with a lost beginning of the tape and during winding, when winding from one take-up reel to the other take-up reel to be changed.

Bei einer bekannten Andrück- und Trennvorrichtung der eingangs genannten Art (US-PS 29 42 796), die allerdings nicht für Metallband, sondern für thermoplastische Folien ausgelegt ist, ist das Messer feststehend in der Baueinheit angeordnet und durchtrennt das Band in einem frei geführten Abschnitt zwischen den beiden Aufwickelhaspeln in der Nähe der neuen Aufwickelhaspel. Bei diesem Trennvorgang wird das Band über das Messer gezogen, weshalb in Bandlaufrichtung Schleifspuren auf dem Band nicht zu vermeiden sind. Für die Durchtrennung eines Metallbandes ist diese Art der Durchtrennung nicht geeignet.In a known pressing and separating device of the type mentioned (US Pat. No. 2,942,796), which, however, is not designed for metal tape, but for thermoplastic films, the knife is fixed in the structural unit and cuts the tape in a freely guided section between the two take-up reels near the new take-up reel. During this separation process, the belt is pulled over the knife, which is why grinding marks on the belt cannot be avoided in the belt running direction. This type of cutting is not suitable for cutting a metal strip.

Der Erfindung liegt die Aufgabe zugrunde, eine Andrück- und Trennvorrichtung der eingangs genannten Art zu schaffen, die bei andauerndem Transport des Bandes eine Durchtrennung des Bandes ohne Beschädigung des Bandes gewährleistet.The invention has for its object to provide a pressing and separating device of the type mentioned, which ensures continuous cutting of the tape without damaging the tape during continuous transport of the tape.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Messer gegen die Aufwickelhaspel drückbar und in Bandlaufrichtung wegklappbar ist.This object is achieved in that the knife can be pressed against the reel and folded away in the direction of tape travel.

Als Andrückmittel ist besonders eine an sich bekannte Bürste geeignet.A brush known per se is particularly suitable as a pressing means.

Vorzugsweise sollte das Messer vor dem Andrück- und Trennvorgang durch Federmittel in einer vorzugsweise quer zur Bandlaufrichtung ausgerichteten Position gehalten werden. Das Anheftmittel kann ein Klebebelag sein.Before the pressing and separating process, the knife should preferably be held by spring means in a position which is preferably oriented transversely to the tape running direction. The attachment means can be an adhesive coating.

Mit der erfindungsgemäßen Vorrichtung ist es möglich, bei hohen Bandgeschwindigkeiten von ca 40m/sek das Band zu trennen und anzuschließen, ohne daß es Probleme gibt. Gleichsam in einem Wischvorgang wird mittels der Bürste das laufende Band an den Wickeldorn angedrückt und dabei das Band durchtrennt. Wegen des wegklappbaren Messers wird das Band nicht beschädigt, vielmehr wird das Messer vom Band in Bandlaufrichtung mitgenommen.With the device according to the invention it is possible to disconnect and connect the tape at high tape speeds of approx. 40 m / sec without problems. As it were in one wiping process, the running belt is pressed onto the winding mandrel by means of the brush, and in the process the Ribbon cut. Because the knife can be folded away, the belt is not damaged, rather the knife is taken along by the belt in the direction of the belt.

Im folgenden wird die Erfindung anhand einer ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. einzelnen zeigen:

  • Fig. 1 die Andrück- und Trennvorrichtung bei einer Vorrich zum Herstellen von gegossenem Band in schematischer Darstellung in Seitenansicht,
  • Fig. 2-5 die Andrück- und Trennvorrichtung gemäß Fig. 1 in verkleinerter Darstellung in verschiedenen Betriebsphasen
  • Fig. 6 u. 7 das Trennmesser der Trennvorrichtung gemäß Fig.1-5 in Ansicht in vergrößerter Darstellung.
The invention is explained in more detail below with the aid of a drawing representing an exemplary embodiment. single show:
  • 1 shows the pressing and separating device in a Vorrich for producing cast tape in a schematic representation in side view,
  • Fig. 2-5 the pressing and separating device according to FIG. 1 in a reduced representation in different operating phases
  • Fig. 6 u. 7 shows the separating knife of the separating device according to FIGS. 1-5 in an enlarged view.

Die Bandgießvorrichtung besteht aus einem mit schmelzflüssigem Metall gefüllten Behälter 1, einem darin eintauchenden Förder- oder Steigrohr 2, einer Gießdüse 3 und einem bewegten Kühlkörper in Form eines gekühlten Gießrades 4. Bandgießvorrichtungen in dieser oder ähnlicher Ausführung sind bekannt. Damit sich infolge der auf das Band 6 einwirkenden Fliehkraft das Band 6 nicht zu früh vom Mantel des Gießrades 4 ablöst, erstreckt sich über das Gießrad 4 eine konzentrisch zum Mantel des Gießrades 4 angeordnete Führung 5, die mit Blasdüsen bestückt ist, die auf das Band 6 blasen und es dadurch gegen den Mantel des Gießrades 4 drücken.The band casting device consists of a container 1 filled with molten metal, a delivery or riser pipe 2 immersed therein, a pouring nozzle 3 and a moving heat sink in the form of a cooled casting wheel 4. Band casting devices in this or a similar embodiment are known. So that due to the centrifugal force acting on the belt 6, the belt 6 does not detach too soon from the jacket of the casting wheel 4, a guide 5, which is equipped with blowing nozzles on the belt, extends over the casting wheel 4 and is arranged concentrically to the jacket of the casting wheel 4 6 blow and thereby press it against the jacket of the casting wheel 4.

Diese spezielle Ausführung der Gießvorrichtung ist von untergeordneter Bedeutung. Bandgießen läßt sich auch zum Beispiel bei Gießvorrichtungen mit zwei Gießrädern oder Gießvorrichtungen mit Düsen zum mehrlagigen Gießen verwirklichen. (Vergl. deutsche Patentanmeldungen P 35 21 778.2 und P 36 02 594.1). Wichtig ist nur, daß an der Ablösestelle des Bandes 6 vom Gießrad 4 das Band 6 erstarrt ist. Eine zum Aufbringen eines Bandzuges ausreichende Zugfestigkeit braucht es hier noch nicht zu haben.This special design of the casting device is of minor importance. Belt casting can also be used, for example, for casting devices with two casting wheels or Realize pouring devices with nozzles for multi-layer pouring. (See German patent applications P 35 21 778.2 and P 36 02 594.1). It is only important that the strip 6 has solidified at the detachment point of the belt 6 from the casting wheel 4. Sufficient tensile strength to apply a tape tension is not yet necessary here.

Zum leichteren Ablösen des Bandes 6 von dem Gießrad 4 ist im Zwickel zwischen dem Mantel des Gießrades 4 und dem Band 6 ein keilförmiges Ablöseorgan 7 angeordnet, das zum Unterstützen des Ablösens mit Blasdüsen bestückt sein kann. Diesem Ablöseorgan 7 ist eine Bürstenwalze 8 mit Reibrollen an ihren Enden nachgeordnet, die auf dem Mantel eines ersten Kühlrades 9 laufen. Die Bürstenwalze 8 drückt das Band 6 gegen den Mantel des Kühlrades 9, so daß vor allem der Bandanfang problemlos in den Eingang eines Führungskanals einläuft, der vom Mantel des Kühlrades 9 und einer konzentrisch dazu angeordneten Führungswand 10 gebildet wird. Dem ersten Kühlrad 9 ist ein zweites Kühlrad 11 mit einer entsprechend angeordneten Führungswand 12 nachgeordnet. Über das Gießrad 4 und die beiden Kühlräder 9, 11 ist das Band 6 S-förmig geführt. Die Führungswände 10, 12 an den Kühlrädern 9, 11 sind mit Blasdüsen bestückt, die ein kühlendes Medium gegen das Band 6 blasen, so daß das Band 6 zum Zwecke einer intensiven Kontaktkühlung fest gegen die Mäntel der Kühlräder 9, 11 gedrückt wird. Als Blasmedium wird vorzugsweise ein gekühltes Medium, insbesondere Luft oder ein Inertgas verwendet. Dies gilt vor allem für das Blasmedium der Düsen am Gießrad 4.For easier detachment of the belt 6 from the casting wheel 4, a wedge-shaped detaching member 7 is arranged in the gusset between the jacket of the casting wheel 4 and the belt 6, which can be equipped with blowing nozzles to support the detachment. This detaching element 7 is followed by a brush roller 8 with friction rollers at its ends, which run on the jacket of a first cooling wheel 9. The brush roller 8 presses the belt 6 against the jacket of the cooling wheel 9, so that, above all, the beginning of the belt easily runs into the entrance of a guide channel which is formed by the jacket of the cooling wheel 9 and a guide wall 10 arranged concentrically therewith. The first cooling wheel 9 is followed by a second cooling wheel 11 with a correspondingly arranged guide wall 12. The belt 6 is guided in an S-shape over the casting wheel 4 and the two cooling wheels 9, 11. The guide walls 10, 12 on the cooling wheels 9, 11 are equipped with blowing nozzles that blow a cooling medium against the band 6, so that the band 6 is pressed firmly against the shells of the cooling wheels 9, 11 for the purpose of intensive contact cooling. A cooled medium, in particular air or an inert gas, is preferably used as the blowing medium. This applies above all to the blowing medium of the nozzles on casting wheel 4.

Am Ausgang des vom Mantel des Kühlrades 11 und der Führungswand 12 gebildeten Führungskanals ist als zusätzliche Führung eine Bürstenrolle 13 angeordnet, die über ein auf dem Mantel des Kühlrades 11 laufendes Reibrad angetrieben wird. An den Führungskanal 11, 12 schließt sich ein flacher Führungskanal 14 an. Die Weite dieses Führungskanals 14 senkrecht zur Bandebene ist kleiner als die Bandbreite. Der Führungskanal 14 kann aus einem U-Profil bestehen, das durch einen seitlichen Deckel verschließbar ist. Durch Öffnen des Deckels und durch seitliches Verstellen ist es möglich, das durch den Kanal 14 geführte Band 6 freizugeben.At the output of the guide channel formed by the jacket of the cooling wheel 11 and the guide wall 12, a brush roller 13 is arranged as an additional guide, which is driven by a friction wheel running on the jacket of the cooling wheel 11. A flat guide channel 14 adjoins the guide channel 11, 12. The width of this guide channel 14 perpendicular to the band plane is smaller than the bandwidth. The guide channel 14 can consist of a U-profile, which can be closed by a side cover. By opening the cover and by lateral adjustment, it is possible to release the band 6 guided through the channel 14.

Mit einer nur angedeuteten Meßeinrichtung 17 läßt sich die Banddicke bei ununterbrochener Förderung des Bandes 6 messen.The strip thickness can be measured with an uninterrupted conveying of the strip 6 with a measuring device 17 which is only indicated.

Am Ausgang des im wesentlichen vertikal verlaufenden Führungskanals 14 ist eine in der Zeichnung nur angedeutete Saugvorrichtung 15 angeschlossen, die einen Gasstrom durch den Kanal von oben nach unten strömen läßt. Dadurch wird das durch den Führungskanal 14 zu fördernde und schon aufgrund seines Eigengewichtes geförderte Band 6 zusätzlich gefördert.At the exit of the essentially vertical guide channel 14, a suction device 15, only indicated in the drawing, is connected, which allows a gas flow to flow through the channel from top to bottom. As a result, the belt 6, which is to be conveyed through the guide channel 14 and is already conveyed on account of its own weight, is additionally conveyed.

Am unteren Ausgang des Führungskanals 14 ist ein Klemmrollenpaar 16 vorgesehen. Das bei geöffneten Klemmrollen 16 zwischen die Klemmrollen 16 einlaufende Band 6 wird von den Klemmrollen 16 gehalten und in Richtung eines Schrottsammelbehälters 18 gefördert. Durch Festklemmen des Bandes 6 ist dieses seitlich fixiert. Deshalb wird von diesem Augenblick an nicht länger der Führungskanal 14 benötigt, sondern er kann geöffnet und aus dem Führungsbereich herausbewegt werden. Mittels einer nicht dargestellten Abtastvorrichtung kann dann die Lage des Bandes 6 erfaßt und für den noch zu beschreibenden Anwickelvorgang benutzt werden.At the lower exit of the guide channel 14, a pair of pinch rollers 16 is provided. The belt 6, which runs in between the clamping rollers 16 when the clamping rollers 16 is open, is held by the clamping rollers 16 and conveyed in the direction of a scrap collecting container 18. By clamping the band 6, it is fixed laterally. From this moment on, the guide channel 14 is therefore no longer required, but can be opened and moved out of the guide area. By means of a scanning device, not shown, the position of the tape 6 can then be detected and used for the winding process to be described.

Im Bereich des Führungskanals 14 ist eine aus zwei Aufwickelhaspeln 19, 20 bestehende Wendehaspel 21 angeordnet, die in Achsrichtung der Aufwickelhaspeln 19, 20 und damit parallel zur Bandebene und senkrecht zur Bandlaufrichtung bewegbar ist. Jeder Aufwickelhaspel 19, 20 ist eine Bandführungsrolle 22, 23 mit seitlichem Abstand zugeordnet, die bei einem Haspelwechsel das Band führt. Der Wickeldorn einer jeden Aufwickelhaspel 19, 20 weist ein auf das Band wirkendes Anheftmittel z.B. einen Klebebelag auf.In the area of the guide channel 14 there is a reversible reel 21 consisting of two winding reels 19, 20 which can be moved in the axial direction of the winding reels 19, 20 and thus parallel to the strip plane and perpendicular to the strip running direction. Each take-up reel 19, 20 is one Band guide roller 22, 23 assigned at a lateral distance, which guides the tape when changing the reel. The winding mandrel of each take-up reel 19, 20 has a tacking agent acting on the tape, for example an adhesive coating.

Auf der den Aufwickelhaspeln 19, 20 gegenüberliegenden Seite des Bandes 6 im Bereich des Führungskanals 14 ist eine Andrück- und Trennvorrichtung 24 angeordnet, die, wie aus Fig.2 und 3 ersichtlich, aus einem vorbewegbaren bürstenförmigen Andrückorgan 25 und einem wegklappbaren gezahnten Messer 26 besteht. Mit dieser Andrück- und Trennvorrichtung 24 läßt sich das mit hoher Geschwindigkeit laufende Band 6 an die in Position befindliche Aufwickelhaspel 19 anschließen.On the side of the band 6 opposite the take-up reels 19, 20 in the region of the guide channel 14, a pressing and separating device 24 is arranged, which, as can be seen in FIGS . With this pressing and separating device 24, the belt 6 running at high speed can be connected to the take-up reel 19 located in position.

Der jeweils in Wechselstellung befindlichen Aufwickelhaspel 19 oder 20 ist eine anschwenkbare Andrückrolle 27 zugeordnet.A respective pivotable pressure roller 27 is assigned to the take-up reel 19 or 20 which is in the change position.

Mit einer solchen Vorrichtung erfolgt die Herstellung von gegossenem Metallband mit armorph und/oder feinkristallinem Gefüge auf folgende Art und Weise:With such a device, cast metal strip with an armorphic and / or finely crystalline structure is produced in the following manner:

Das auf das Gießrad 4 aufgebracht schmelzflüssige Metall wird unter Zuhilfenahme des Ablöseorgans 7 und der Bürstenwalze 8 in den ersten Abschnitt eines von Kühlrädern 9, 11 und Führungswänden 10, 12 gebildeten Führungskanal eingebracht. Das Band 6 hat beim Verlassen des Gießrades 4 noch eine sehr geringe Festigkeit, erhält dann aber von den Kühlrädern 9, 11 eine derart starke Kühlung, daß es beim Verlassen des ersten Abschnittes des Führungskanals ausreichend fest ist, im frei geführt zu werden. Es durchläuft dann den senkrecht angeordneten Führungskanal 14, von dem es in den Schrottsammelbehälter 18 einläuft. Diese Betriebsphase ist in Figur 1 dargestellt.The molten metal applied to the casting wheel 4 is introduced into the first section of a guide channel formed by cooling wheels 9, 11 and guide walls 10, 12 with the aid of the detaching member 7 and the brush roller 8. The belt 6 has a very low strength when leaving the casting wheel 4, but then receives such a strong cooling from the cooling wheels 9, 11 that it is sufficiently firm when leaving the first section of the guide channel to be guided freely. It then passes through the vertically arranged guide channel 14, from which it enters the scrap collecting container 18. This operating phase is shown in Figure 1.

Zur Vorbereitung des Anschließens des Bandes 6 an die Aufwickelhaspel 19 werden die Klemmrollen 16 der Fangvorrichtung angestellt. Die angetriebenen Klemmrollen 16 übernehmen die Führung des Bandes 6 und erhalten es straff. Der Bandführungskanal 14 kann dann entfernt werden. Mittels der der Zeichnung nicht dargestellten Abtasteinrichtung für die Lage des Bandes 6 wird die Lage des Bandes erfaßt. In Abhängigkeit von diesem Meßergebnis findet eine Ausrichtung des Bandes 6 und der Aufwickelhaspel 19 zueinander statt, z.B. dadurch, daß bei unveränderter Bandführung der Aufwickelhaspel 19 axial verfahren wird. Anschließend wird das Klemmrollenpaar 16 in Richtung auf Aufwickelhaspel 19 verstellt und die Andrück- und Trennvorrichtung 24 gegen das Band 6 bewegt, um das Band an den Klebebelag des Dorns der Aufwickelhaspel 19 anzuheften. Dabei drückt die Bürste 25 das laufende Band in einer Wischbewegung an. Das wegklappbare, federnd gelagerte Messer 26 wird durch das laufende Band 6 weggeklappt und behindert deshalb die Bewegung des Bandes ebenfalls nicht. Nach dem Anschließen des Bandes wird das Klemmrollenpaar 16 und die Andrück- und Trennvorrichtung 24 in ihre Ruhestellung zurückgebracht. Das Band 6 wird auf die Haspel 19 aufgewickelt, bis daß die Aufwickelhaspel 19 voll ist. Sobald die Aufwickelhaspel 19 vollgewickelt ist, wird die Wendehaspel 21 verschwenkt, so daß die leere Aufwickelhaspel 20 in die Position der vollen Aufwickelhaspel 19 gelangt. Bei diesem Wendevorgang braucht die Förderung des Bandes nicht unterbrochen zu werden. Das noch auf die Aufwickelhaspel 19 aufgewickelte Band wird nach dem Schwenkvorgang über die Führungsrolle 23 geführt, die dafür sorgt, daß das Band 6 im wesentlichen senkrecht vorbei an der leeren Haspel 20 zum Anschließen an deren Dorn geführt wird. Diese Betriebsphase ist in Fig. 1 gestrichelt dargestellt. Wie beim ersten Anschließen des Bandes wird die Andrück- und Trennvorrichtung 24 wieder betätigt. Vor deren Betätigung wird allerdings die schwenkbare Andrückrolle 27 auf den Rollenwickel 28 gedrückt, damit nach Trennen des Bandes der Bund 28 straff gewickelt bleibt. Diese Nach dem Trennen des Bandes und Anheften des neuen Bandanfangs am Dorn der Aufwickelhaspel 20 kann der Wickel 28 vom Dorn der Aufwickelhaspel 19 abgezogen und mit einer neuen Wickelhülse bestückt werden.To prepare the connection of the band 6 to the take-up reel 19, the pinch rollers 16 of the safety gear are turned on. The driven pinch rollers 16 take over the leadership of the belt 6 and keep it taut. The tape guide channel 14 can then be removed. The position of the band is detected by means of the scanning device, not shown in the drawing, for the position of the band 6. Depending on this measurement result, the tape 6 and the take-up reel 19 are aligned with one another, for example by moving the take-up reel 19 axially with the tape guide unchanged. The pair of pinch rollers 16 is then adjusted in the direction of the take-up reel 19 and the pressing and separating device 24 is moved against the tape 6 in order to attach the tape to the adhesive coating of the mandrel of the take-up reel 19. The brush 25 presses the running belt in a wiping motion. The collapsible, spring-mounted knife 26 is folded away by the running belt 6 and therefore does not hinder the movement of the belt either. After connecting the tape, the pair of pinch rollers 16 and the pressing and separating device 24 are returned to their rest position. The tape 6 is wound on the reel 19 until the reel 19 is full. As soon as the take-up reel 19 is fully wound, the turning reel 21 is pivoted so that the empty take-up reel 20 comes into the position of the full take-up reel 19. The conveying of the belt need not be interrupted during this turning process. The still wound on the take-up reel 19 is guided after the pivoting process over the guide roller 23, which ensures that the tape 6 is guided substantially vertically past the empty reel 20 for connection to the mandrel. This operating phase is shown in dashed lines in FIG. 1. As when connecting the tape for the first time, the pressing and separating device 24 is actuated again. Before it is actuated, however, the pivotable pressure roller 27 pressed onto the roll winder 28 so that the bundle 28 remains tightly wound after the tape is cut. After the tape has been separated and the new tape start has been attached to the mandrel of the take-up reel 20, the winding 28 can be pulled off the mandrel of the take-up reel 19 and fitted with a new winding tube.
