Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von Schuppenbandrollen aus geschuppt übereinander auf ein Förderband abgelegten flachen flexiblen Gegenständen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for producing scale belt rolls from flat flexible objects, which are shingled one above the other on a conveyor belt, according to the preamble of patent claim 1.

Bei einer aus der DE-A-2 544 135 bekannten Vorrichtung dieser Art werden die geschuppt übereinanderliegenden flachen Gegenstände in der Formation zu einer Schuppenbandrolle aufgewickelt, wie sie von der zuführenden Fördereinrichtung an den gleichzeitig die sich bildende Schuppenbandrolle antreibenden Bandförderer übergeben werden. Nun kann es jedoch zu Störungen oder Unregelmässigkeiten bei der einander teilweise überdeckenden Ablage der Gegenstände oder während des Transports des auf diese Weise gebildeten Schuppenbandes zu unterschiedlich grossen Überlappungslängen der Gegenstände kommen, die sich beim Aufwickeln des Schuppenbandes zu einer Schuppenbandrolle störend auswirken und zu unrunden Rollen führen können.In a device of this type known from DE-A-2 544 135, the shingled, flat objects lying one above the other are wound up in the formation to form a scale belt roll, as they are transferred from the supplying conveying device to the belt conveyor simultaneously driving the forming scale belt roll. However, malfunctions or irregularities in the partially overlapping depositing of the objects or during the transport of the scale band formed in this way can lead to different lengths of overlap of the objects, which have a disruptive effect when the scale band is wound up to form a scale band roll and lead to non-round rolls can.

Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs angegebenen Art zu schaffen, bei der sich unterschiedlich grosse Überlappungslängen der geschuppt übereinanderliegenden Gegenstände vor dem Aufwickeln vergleichmässigen lassen.The object of the invention is therefore to provide a device of the type specified at the outset, in which overlapping lengths of the shingled objects of different sizes can be made uniform before winding up.

Erfindungsgemäss wird diese Aufgabe durch die in dem kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in the characterizing part of patent claim 1.

Wegen des Trägheitsmoments lässt sich die sich bildende Schuppenbandrolle nicht schlagartig anhalten und wieder in Drehung versetzen. Dennoch führt der auf unterschiedliche Überlappungslängen angepasste Antrieb des Förderbandes zur Vergleichmässigung der Überlappungslängen, die zu einer verbesserten Wickelqualität führt.Due to the moment of inertia, the formed scale belt roll cannot be stopped suddenly and set in rotation again. Nevertheless, the drive of the conveyor belt, which is adapted to different overlap lengths, leads to an equalization of the overlap lengths, which leads to an improved winding quality.

Bei einer aus der EP-A-013 920 bekannten Vorrichtung zum Zuführen von geschuppt übereinander auf einem Förderband liegenden flachen Werkstücken zu einem nachfolgenden Förderer werden die Nachlaufkanten der Werkstücke von einem Signalgeber erfasst und einer den Antriebsmotor des nachfolgenden Förderers steuernden Einrichtung über einen Drehzahlgeber zugeführt, so dass der Antriebsmotor derart langsamer läuft, dass auf dem nachfolgenden Förderer angeordnete Greifer jeweils etwa deckungsgleich zusammengeschobene Werkstücke erfassen. Bei der bekannten Vorrichtung wird also entsprechend den Signalen des Signalgebers die Fördergeschwindigkeit des die geschuppt übereinanderliegenden Werkstücke fördernden Förderers gegenüber der Geschwindigkeit des nachfolgenden Förderers derart vermindert, dass dessen Greifer jeweils zwei Werkstücke erfassen können.In a device known from EP-A-013 920 for feeding flat workpieces lying in shingled fashion on a conveyor belt to a subsequent conveyor, the trailing edges of the workpieces are detected by a signal transmitter and fed to a device controlling the drive motor of the subsequent conveyor via a speed transmitter, so that the drive motor runs so slowly that grippers arranged on the following conveyor each grip workpieces pushed together approximately congruently. In the known device, the conveying speed of the conveyor which conveys the shingled superimposed workpieces is thus reduced in relation to the speed of the following conveyor in accordance with the signals of the signal transmitter in such a way that its grippers can each grip two workpieces.

Um einen hohen Ausnutzungsgrad zu erreichen, ist in weiterer Ausgestaltung der Erfindung vorgesehen, dass auf einer quer zu dem Bandförderer angeordneten Achse zwei Schwenkarme längsverschieblich gelagert sind, die an ihren Enden je einen Wickelkern aufnehmende Zapfen tragen. Die Schwenkarme lassen sich einfach und schnell in der Weise hin-und herschieben, dass sich jeweils ein Zapfen in der Wickelposition befindet, während der andere ausserhalb des Bandförderers liegt, so dass die fertig gewickelte Schuppenbandrolle abgenommen und ein neuer Wickelarm aufgesetzt werden kann.In order to achieve a high degree of utilization, it is provided in a further embodiment of the invention that two swivel arms are mounted in a longitudinally displaceable manner on an axis arranged transversely to the belt conveyor, each of which carries a cone receiving pins at their ends. The swivel arms can be easily and quickly moved back and forth in such a way that one pin is in the winding position while the other is outside the belt conveyor, so that the finished wound scale belt roll can be removed and a new winding arm can be attached.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben worden.Further advantageous embodiments of the invention have been described in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. In dieser zeigt:

  • Fig. 1 eine Seitenansicht der Wickelvorrichtung in schematischer Darstellung und
  • Fig. 2 eine Draufsicht auf die Wickelvorrichtung nach Fig. 1.
An embodiment of the invention is explained below with reference to the drawing. In this shows:
  • Fig. 1 is a side view of the winding device in a schematic representation
  • FIG. 2 is a plan view of the winding device according to FIG. 1.

Die Schuppe wird, wie in Fig. 1 dargestellt, der Sackaufwickelvorrichtung zugeführt. Da der Schuppenabstand der ankommenden Werkstücke unter Umständen variiert, ist eine Einrichtung für gleichen Schuppenabstand vorgesehen, damit eine gleichmässig gewickelte Vorratsrolle gebildet werden kann.The scale, as shown in Fig. 1, is fed to the bag winder. Since the scale spacing of the incoming workpieces may vary, a device for the same scale spacing is provided so that a uniformly wound supply roll can be formed.

Zu diesem Zweck ist auf der Schuppe eine Andrückrolle 25 vorgesehen. Die Schuppe wird mit relativ grosser Geschwindigkeit und grossen Abständen gefahren. Auf der gegenüberliegenden Seite, also unterhalb der Schuppe, ist ein Fühler 26 angeordnet, der die Werkstückenden abtastet, dessen Impulse an eine elektrische Zwischenschaltung 27 weitergegeben werden.For this purpose, a pressure roller 25 is provided on the scale. The scale is driven at a relatively high speed and at great distances. On the opposite side, ie below the scale, there is a sensor 26 which scans the workpiece ends, the pulses of which are passed on to an electrical intermediate circuit 27.

Die Schuppe wird nach der Abtastung durch den Fühler 26 auf ein endloses, aus einzelnen Gurten gebildetes Förderband 28 abgeworfen, das über die Rollen 29 bis 34 läuft, die in einem schwenkbaren Gestell 35 drehbar gelagert sind. Am Gestell 35 ist auch die Antriebswalze 36 befestigt, über das die Trume zu den Rollen 29 zurückgeführt werden. Das Gestell 35 ist um die Achse der Rollen 31 schwenkbar gelagert und wird etwa unter der zu wickelnden Vorratsrolle 37 durch Pneumatikzylinder 38 abgestützt, die die Aufgabe haben, das Gestell 35 der Vorratsrolle 37 nachzuführen, um Unrundheiten der Vorratsrolle 37, die während des Wickelns auftreten können, auszugleichen. Ausserdem ist eine Vorratswelle 39 auf flurfester Lagerung vorgesehen, von der Haltebänder 40 abgezogen werden, die in bekannter Weise in Lagen mit den Werkstücken auf der Vorratsrolle 37 aufgewickelt werden.After being scanned by the sensor 26, the scale is thrown onto an endless conveyor belt 28 which is formed from individual belts and runs over the rollers 29 to 34 which are rotatably mounted in a pivotable frame 35. The drive roller 36 is also attached to the frame 35, via which the strands are returned to the rollers 29. The frame 35 is pivotally mounted about the axis of the rollers 31 and is supported, for example, under the supply roller 37 to be wound by pneumatic cylinders 38, which have the task of tracking the frame 35 of the supply roller 37 in order to avoid out-of-roundness of the supply roller 37 which occurs during winding can compensate. In addition, a supply shaft 39 is provided on floor-mounted storage, from which holding straps 40 are pulled, which are wound up in layers in a known manner with the workpieces on the supply roll 37.

Die Achse der Antriebswalze 36 ist mit einem Drehimpulsgeber 41 ausgestattet, dessen Impulse auf einen Zähler 42 eingegeben werden. Der Zähler 42 und der nicht dargestellte Antriebsmotor der Antriebswalze 36 sind mit der Zwischenschaltung 27 elektrisch verbunden. Der Zähler 42 kann auf eine vorbestimmte Zahl eingestellt werden und ist so geschaltet, dass der Antriebsmotor nach Erreichen dieser Zahl stillgesetzt wird. Die vorbestimmte Zahl wird etwas grösser gewählt als dem beabsichtigten Schuppenabstand entspricht. Durch den Fühler 26 wird beim Vorbeigang eines Werkstückendes der Zähler 42 auf Null zurückgestellt. Bleibt also ein Werkstück aus, so dass der Zähler 42 die vorbestimmte Zahl erreicht, wird das Förderband 28 stillgesetzt und es beginnt erst dann wieder nach Durchlauf des nächsten Werkstückes anzulaufen. Daher wird auf dem Förderband 28 annähernd gleicher Schuppenabstand erzielt.The axis of the drive roller 36 is equipped with a rotary pulse generator 41, the pulses of which are input to a counter 42. The counter 42 and the drive motor, not shown, of the drive roller 36 are electrically connected to the intermediate circuit 27. The counter 42 can be set to a predetermined number and is switched so that the drive motor is stopped after reaching this number. The predetermined number is chosen somewhat larger than the intended scale spacing. The sensor 42 is reset to zero when a workpiece end passes by the sensor 26. If there is no workpiece, so that the counter 42 reaches the predetermined number, the conveyor belt 28 is stopped and it only starts again after the next workpiece has run through. Therefore, approximately the same scale distance is achieved on the conveyor belt 28.

Der Kern 45 der Vorratsrolle 37 wird durch einen Zapfen 46 gehalten, der im freien Ende eines Hebels 47 befestigt ist. Das andere Ende des Hebels 47 ist auf einer Buchse 48 zusammen mit einen zweiten Hebelarm 49 drehbar gelagert. Der Hebelarm 49 trägt einen dem Zapfen 46 entsprechenden Zapfen 50 auf seinem freien Ende, der jedoch sich in entgegengesetzter Richtung erstreckt. An die Hebelarme 47 und 49 sind Druckmittelzylinder 51, 52 angelenkt, mit denen sie bzw. die Vorratsrolle 37 auf das Förderband 28 abgesenkt und von dort angehoben werden können.The core 45 of the supply roll 37 is held by a pin 46 which is fastened in the free end of a lever 47. The other end of the lever 47 is rotatably mounted on a bush 48 together with a second lever arm 49. The lever arm 49 carries a pin 50 corresponding to the pin 46 on its free end, but which extends in the opposite direction. Pressure medium cylinders 51, 52 are articulated to the lever arms 47 and 49, with which they or the supply roll 37 can be lowered onto the conveyor belt 28 and raised from there.

Die Buchse 48 ist leichtgängig längsverschieblich auf einer Achse 53 gelagert, die in einem beidseitig neben dem Förderband 28 angeordneten Ständer 54 befestigt ist. Mit der Buchse 48 ist ein Führungsteil 55 durch einen Steg 56 verbunden. Auf dem Führungsteil 55 ist lose drehbar eine Rolle 57 angebracht, die in einem U-Eisen 58 läuft, das die beiden Ständer 54 verbindet. Die freien Enden der Druckmittelzylinder 51, 52 sind am Führungsteil 56 angelenkt. Die Buchse 48 kann nun mit den Hebeln 47, 49 beliebig verschoben werden, so dass einmal der Zapfen 46 sich über dem Förderband 28 und der Zapfen 50 sich ausserhalb des Aufwickelbereiches befindet. Während auf dem Zapfen 46 eine neue Vorratsrolle 37 aufgewickelt wird, kann die fertige Vorratsrolle vom Zapfen 50 abgenommen und ein neuer Kern 45 vorbereitet werden. Nach dem Fertigstellen der Vorratsrolle 37 auf dem Zapfen 46 wird diese mittels des Druckmittelzylinders 51 von dem Förderband 28 abgehoben und die Buchse 48 in ihre andere Extremstellung verschoben sowie die Vorratsrolle 37 auf dem Hallenboden abgesenkt und vom Zapfen 46 abgezogen.The bushing 48 is smoothly and longitudinally displaceably mounted on an axis 53 which is fastened in a stand 54 arranged on both sides next to the conveyor belt 28. A guide part 55 is connected to the bushing 48 by a web 56. A roller 57 is loosely rotatably mounted on the guide part 55 and runs in a U-iron 58 which connects the two stands 54. The free ends of the pressure medium cylinders 51, 52 are articulated on the guide part 56. The bushing 48 can now be moved as desired with the levers 47, 49, so that the pin 46 is located above the conveyor belt 28 and the pin 50 is outside the winding area. While a new supply roll 37 is being wound on the pin 46, the finished supply roll can be removed from the pin 50 and a new core 45 can be prepared. After completion of the supply roll 37 on the pin 46, it is lifted off the conveyor belt 28 by means of the pressure medium cylinder 51 and the bush 48 is shifted into its other extreme position, and the supply roll 37 is lowered on the hall floor and pulled off the pin 46.

Bei den die Hebel 47, 49 mit dem schlittenförmigen Führungsteil 55 verbindenden Druckmittelzylindern 51, 52 handelt es sich um hydraulische Kolben-Zylinder-Einheiten, während die über das rahmenförmige Gestell 35 laufenden Förderbänder durch einen Pneumatikzylinder 38 an den Wickelkern bzw. die sich bildende Schuppenbandrolle 37 angedrückt werden. Der Pneumatikzylinder 38 hat etwa einen Hub von 100 mm und wird dadurch in seiner Mittellage gehalten, dass die Hydraulikzylinder 51, 52 die Hebel 47, 49 entsprechend dem Wickelfortschritt anheben. Die Hydraulikzylinder 51, 52 können dadurch betätigt werden, dass der Pneumatikzylinder mit einem Endschalter versehen ist. Der Pneumatikzylinder 38 hat gute federnde Eigenschaften, so dass er Unrundheiten der sich bildenden Schuppenbandrolle 37 auszugleichen vermag.The pressure medium cylinders 51, 52 connecting the levers 47, 49 to the sled-shaped guide part 55 are hydraulic piston-cylinder units, while the conveyor belts running over the frame-shaped frame 35 pass through a pneumatic cylinder 38 to the winding core or the forming scale roll 37 can be pressed. The pneumatic cylinder 38 has a stroke of approximately 100 mm and is held in its central position by the hydraulic cylinders 51, 52 lifting the levers 47, 49 in accordance with the winding progress. The hydraulic cylinders 51, 52 can be actuated in that the pneumatic cylinder is provided with a limit switch. The pneumatic cylinder 38 has good resilient properties, so that it is able to compensate for out-of-roundness of the scale roller 37 that is being formed.
