The axis (6)of the roll core (7) is kept horizontal and the rolls are arranged below the strip feed device.

Description

Die Erfindung betrifft eine Aufwickelvorrichtung für Bahnen aus duroplastischen Compoundmassen, insbesondere SMC, auf Transportrollen.The invention relates to a winding device for webs made of thermosetting Compound masses, especially SMC, on transport rollers.

SMC (sheet moulding compound) sind bekannte duroplastische Compoundmassen, die in Form von dünnen Platten vorliegen und im Preßverfahren geformt werden.SMC (sheet molding compound) are known thermosetting compound compounds, which are in the form of thin plates and are formed in the pressing process.

Das SMC wird mit herkömmlichen Maschinen hergestellt und entweder auf einen Wickelkern zu Transportrollen aufgerollt oder zickzackgefaltet in Kisten verpackt.The SMC is manufactured with conventional machines and either on one The winding core is rolled up into transport rolls or zigzag folded and packed in boxes.

Bei der Herstellung der Transportrollen wird normalerweise ein Wendegetriebe eingesetzt (siehe Fig. 1), damit die SMC-Maschine nicht gestoppt zu werden braucht.A reversing gear is normally used in the manufacture of the transport rollers used (see Fig. 1) so that the SMC machine does not need to be stopped.

Das Wendegetriebe besteht aus einer Schwinge 1, auf der zwei leere Transportrollen 2 angeordnet sind, die von einem Motor 3a angetrieben sind. Wenn die erste Rolle ihr Sollgewicht erreicht hat, wird die SMC-Bahn 4 geschnitten und die Schwinge 1 kippt, vom Motor 3b angetrieben, die zweite Transportrolle 2 in die Füllposition. Anschließend wird die SMC-Bahn 4 auf den Wickelkern der zweiten Transportrolle gelegt (siehe Fig. 2) und die gefüllte Transportrolle abgenommen und auf ein Metallgestell gesetzt (siehe Fig. 3). Eine leere Transportrolle wird anschließend auf das Wendegetriebe aufgesetzt. Bei diesen Wendegetrieben werden die Transportrollen daher ständig und ohne Produktionsunterbrechung gewechselt.The reversing gear consists of a swing arm 1 on which two empty transport rollers 2 are arranged, which are driven by a motor 3a. If the first role you Has reached the target weight, the SMC web 4 is cut and the rocker 1 tilts, driven by the motor 3b, the second transport roller 2 in the filling position. The SMC web 4 is then placed on the winding core of the second transport roll placed (see Fig. 2) and the filled transport roll removed and on Metal frame set (see Fig. 3). An empty transport roll is then opened the reversing gear put on. With these reversing gearboxes Transport rollers are therefore constantly changed and without interrupting production.

Das Metallgestell Fig. 3, das die Transportrollen aufnimmt, ist auf 2 bis 4 Transportrollen ausgelegt, im allgemeinen jedoch auf 4.The metal frame Fig. 3, which receives the transport rollers, is on 2 to 4 Transport rollers designed, but generally on 4.

Das Gesamtgewicht des auf dem Gestell gelagerten SMC beträgt 800 bis 1600 kg bei 2 bis 4 Rollen. The total weight of the SMC mounted on the frame is 800 to 1600 kg 2 to 4 rolls.

Das beschriebene System weist verschiedene Nachteile auf

  • I. Zwei Vorgänge sind erforderlich:
    • Wickeln um einen Kern
    • Ablagen der Transportrolle auf einem Metallgestell
  • II. Die Vorgänge müssen für jede Transportrolle wiederholt werden.
  • III. Eine Erhöhung des Gewichts der Transportrolle auf mehr als 600 kg bewirkt eine Zunahme des Platzbedarfs und der Größe des Wendegetriebes.
  • IV. Eine Erhöhung des Gewichts der Transportrolle bewirkt eine Erhöhung der Leistung des Motors, der das Wendegetriebe antreibt.
    • The system described has several disadvantages
  • I. Two operations are required:
    • Wrap around a core
    • Storage of the transport roll on a metal frame
  • II. The processes must be repeated for each transport roll.
  • III. An increase in the weight of the transport roller to more than 600 kg causes an increase in the space requirement and the size of the reversing gear.
  • IV. Increasing the weight of the transport roller increases the power of the motor that drives the reversing gear.

    • Der Erfindung liegt die Aufgabe zugrunde, eine Aufwickelvorrichtung nach dem Oberbegriff des Anspruch 1 so zu verbessern, daß auch schwerere Transportrollen bei geringem Platzbedarf auf einfache Weise bewickelt werden können.The invention has for its object a winding device according to the Improve the preamble of claim 1 so that even heavier transport rollers can be easily wrapped with a small footprint.

    Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß

    • die Transportrollen auf einzelnen transportablen Gestellen drehbar gelagert sind,
    • daß die Achse des Wickelkerns der Transportrollen in horizontaler Richtung angeordnet sind und
    • daß die Transportrollen unterhalb der Zuführvorrichtung für die Bahn angeordnet sind.
    According to the invention this object is achieved in that
    • the transport rollers are rotatably mounted on individual transportable frames,
    • that the axis of the winding core of the transport rollers are arranged in the horizontal direction and
    • that the transport rollers are arranged below the feed device for the web.

    Dies hat den Vorteil, daß auch sehr schwere Transportrollen auf einfache Weise bewickelt werden können. Der Platzbedarf ist erheblich verringert. This has the advantage that even very heavy transport rollers in a simple manner can be wound. The space requirement is significantly reduced.

    Vorteilhafterweise weisen die Transportrollen seitliche Wangen auf und sind auf den Gestellen auf Rollkörpern gelagert.Advantageously, the transport rollers have side cheeks and are on the Racks stored on rolling bodies.

    Der Antrieb für die Transportrollen beim Aufwickelvorgang ist sinnvollerweise durch einen an der Maschine zur Herstellung der Bahn (SMC-Bahn) angeordneten Geber gesteuert.The drive for the transport rollers during the winding process is usefully through an encoder arranged on the machine for producing the web (SMC web) controlled.

    In vorteilhafter Ausgestaltung ist unterhalb der Zuführvorrichtung für die Bahn neben der aufwickelnden Transportrolle eine leere Transportrolle angeordnet, die bei Bedarf von einem Stellzylinder in die Füllposition verschoben wird. Da die Transportrolle auf einem Gestell angeordnet ist, wird das gesamte Gestell verschoben. Bevorzugt weist die Zuführvorrichtung eine Schneidvorrichtung zum Abschneiden der Bahn auf.In an advantageous embodiment is below the feed device for the web the winding transport roll an empty transport roll arranged, if necessary is moved from an actuating cylinder to the filling position. Because the transport roll on a frame is arranged, the entire frame is moved. Preferably points the feeder includes a cutter for cutting the web.

    In bevorzugter erfindungsgemäßer Ausführungsform beträgt der Durchmesser des Wickelkerns der Transportrollen mindestens 400 mm, bevorzugt liegt er zwischen 400 und 600 mm.In a preferred embodiment according to the invention, the diameter of the Winding core of the transport rollers at least 400 mm, preferably it is between 400 and 600 mm.

    Weitere Merkmale der Erfindung ergeben sich aus den Figuren, die nachfolgend beschrieben sind.

  • Die Figuren 1 und 2 zeigen ein Wendegetriebe nach dem Stand der Technik, wie schon in der Beschreibungseinleitung erläutert. Fig. 3 zeigt ein zugehöriges Metallgestell auf dem die Transportrollen 2 gelagert werden.
  • Fig. 4 veranschaulicht das erfindungsgemäße Aufwickelsystem. Mit dem Bezugszeichen 12 ist eine bekannte Maschine zum Herstellen einer SMC-Bahn 4 bezeichnet. Neben dieser Maschine 12 sind zwei Gestelle 5 angeordnet, auf denen sich jeweils eine Transportrolle 2 befindet. Die Gestelle 5 sind mit Kufen 16 versehen, so daß sie sich leicht verschieben lassen. Auf den Gestellen 5 sind die Transportrollen 2 auf Rollkörpern 10 drehbar gelagert. Hierzu weisen die Transportrollen 2 seitliche Wangen 9 auf
    • Further features of the invention emerge from the figures, which are described below.
  • Figures 1 and 2 show a reversing gear according to the prior art, as already explained in the introduction to the description. Fig. 3 shows an associated metal frame on which the transport rollers 2 are stored.
  • Fig. 4 illustrates the winding system according to the invention. Reference number 12 denotes a known machine for producing an SMC web 4. In addition to this machine 12, two frames 5 are arranged, on each of which a transport roller 2 is located. The frames 5 are provided with runners 16 so that they can be easily moved. On the frames 5, the transport rollers 2 are rotatably mounted on roller bodies 10. For this purpose, the transport rollers 2 have lateral cheeks 9

    • Die Transportrollen 2 haben eine Breite von bevorzugt 1,50 m und der Durchmesser des Wickelkerns beträgt mindestens 400 mm und liegt bevorzugt zwischen 400 und 600 mm.The transport rollers 2 have a width of preferably 1.50 m and the diameter of the winding core is at least 400 mm and is preferably between 400 and 600 mm.

    Nachdem die SMC-Bahn 4 die Maschine 12 verlassen hat, gelangt sie zu einer Zuführvorrichtung 8, die oberhalb der Transportrollen 2 angeordnet ist. Dieser Zuführvorrichtung 8 ist eine Schneidvorrichtung 15 zugeordnet, mit der die SMC-Bahn 4 abgeschnitten werden kann.After the SMC web 4 has left the machine 12, it arrives at one Feed device 8, which is arranged above the transport rollers 2. This Feeding device 8 is assigned a cutting device 15 with which the SMC web 4 can be cut off.

    Die Transportrollen 2 werden von einem Antrieb 11 angetrieben, der von einem an der Maschine 12 angeordneten Geber 13 gesteuert ist.The transport rollers 2 are driven by a drive 11, the one of the Machine 12 arranged encoder 13 is controlled.

    Fig. 4 zeigt, wie gerade die Transportrolle 2a bewickelt wird. Wenn diese Transportrolle 2a ihr Sollgewicht erreicht hat, schneidet die Schneidvorrichtung 15 die SMC-Bahn 4 ab. Anschließend verschiebt der Stellzylinder 14 die leere Transportrolle 2b in die Füllposition und die SMC-Bahn 4 wird auf den Wickelkern 7 dieser Transportrolle 2b gelegt. Vorteilhaft ist, daß der Stellzylinder 14 jeweils zwei Transportrollen 2a, 2b gleichzeitig verschiebt. So wird beim Verschieben der leeren Transportrolle 2b auch gleichzeitig die volle Transportrolle 2a in eine Lagerposition verschoben.Fig. 4 shows how the transport roller 2a is being wound. If those Transport roller 2a has reached its target weight, the cutting device 15 cuts the SMC lane 4 from. The actuating cylinder 14 then moves the empty transport roller 2b in the filling position and the SMC web 4 is on the winding core 7 of this Transport roller 2b placed. It is advantageous that the actuating cylinder 14 has two Transport rollers 2a, 2b moves at the same time. So when moving the empty one Transport roller 2b also simultaneously the full transport roller 2a in a storage position postponed.

    Mit dieser Aufwickelvorrichtung lassen sich einfach 1600 kg-Rollen herstellen.With this rewinder, 1600 kg rolls can be easily produced.

    Die Vorteile sind:

  • a) Die Wickel- und Endlagerungsvorgänge fallen zusammen. Dadurch entfällt ein Vorgang.
  • b) Möglichkeit, sehr schwere Rollen (> 1000 kg) bei geringem Platzbedarf und geringen Motorleistungen herzustellen.
    • The advantages are:
  • a) The winding and final storage operations coincide. This eliminates an operation.
  • b) Possibility to produce very heavy rolls (> 1000 kg) with a small footprint and low engine power.

    • Wenn beispielsweise 1600-kg-Rollen mit einem herkömmlichen Walzenwendesystem und einer SMC-Breite von 1,50 m hergestellt werden sollen, würden sich die folgenden Vergleichswerte ergeben:

    Figure 00050001
    If, for example, 1600 kg rolls are to be produced with a conventional roll turning system and an SMC width of 1.50 m, the following comparison values would result:
