Description

Die Erfindung betrifft eine Vorrichtung zum Entladen von Spulen aus Spulenförderelementen und zum Umsetzen der Spulen in für die Weiterbehandlung der Spulen geeignete Positionen.The invention relates to a device for unloading coils from coil conveying elements and for converting the coils into positions suitable for the further treatment of the coils.

In der DE-38 24 874 A1 ist eine Spulentransportund Spulenumsetzvorrichtung beschrieben, bei der Spulen, die in liegender Stellung, das heißt in Bezug auf ihre jeweiligen Achsen im wesentlichen in horizontaler Richtung ausgerichtet sind, von einem Bandförderelement zugefördert werden, zuerst mittels eines flügelradähnlichen Umsetzaggregates aufgerichtet, anschließend von einem Greifer ergriffen und dann auf Paletten abgestellt werden.DE-38 24 874 A1 describes a bobbin transport and bobbin transfer device in which bobbins which are oriented in the horizontal position, i.e. essentially in the horizontal direction with respect to their respective axes, are fed by a belt conveyor element, first by means of a vane-wheel-like transfer unit erected, then gripped by a gripper and then placed on pallets.

Insgesamt werden derartige Vorrichtungen dazu benötigt, um vollbewickelte Spulen, z.B. Kreuzspulen, die in Abhängigkeit von vorhergehenden Arbeitsprozessen einzeln oder gruppenweise eine erste Position einnehmen können, in eine solche Stellung zu bringen, daß sie entsprechend den unterschiedlichsten Kunden- bzw. Abnehmerwünschen oder in Anpassung an folgende Verarbeitungsstufen eine vorgeschriebene zweite Position einnehmen. Dieses gilt z.B. für das Palettieren oder das Verpacken von fertigen Spulen in Kartons oder sonstigen Behältnissen.Overall, devices of this type are required to feed fully wound coils, e.g. To bring cross-wound bobbins, which, depending on previous work processes, individually or in groups, into a first position, in such a position that they assume a prescribed second position according to the most varied customer or customer wishes or in adaptation to the following processing stages. This applies e.g. for palletizing or packing finished bobbins in boxes or other containers.

Um dieses Ziel zu erreichen, ist die erfindungsgemäße Vorrichtung gekennzeichnet durch eine Übergabestation, eine Fördereinrichtung, die durch zwei endlose, in bestimmtem Abstand voneinander parallel laufende Förderriemen gebildet ist, auf die die einzelne Spule von dem jeweiligen Spulenförderelement mittels der Übergabestation mit der Spulenmantelfläche abgelegt wird, einen zwischen den beiden Förderriemen angeordneten, um eine Vertikalachse drehbaren Hubtisch, der die Spulen durch die Auf- und Abbewegung zeitweise von den Förderriemen abhebt, sie um 180° dreht und wieder auf den Förderriemen ablegt, und ein in Förderrichtung der beiden Förderriemen hinter dem Hubtisch angeordnetes, zwischen die beiden Förderriemen greifendes und um eine Horizontalachse drehberes Umsetzaggregat, das als taktweise von einem Motor oder 180° -Drehzylinder angetriebenes Flügelrad ausgebildet ist und das die einzelnen zwischen den beiden Förderriemen auf ihrer Mantelfläche abgestützte Spule aufnimmt und durch Drehung seiner Horizontalachse umsetzt und mit einer Stirnfläche der Spule wieder auf den Förderriemen ablegt.In order to achieve this goal, the device according to the invention is characterized by a transfer station, a conveying device which is formed by two endless conveyor belts running parallel and at a certain distance from one another, onto which the individual spool is deposited by the respective spool conveying element by means of the transfer station with the surface of the spool , a lifting table arranged between the two conveyor belts, which can be rotated about a vertical axis and which occasionally lifts the bobbins from the conveyor belts due to the up and down movement, rotates them by 180 ° and places them back on the conveyor belt, and one in the conveying direction of the two conveyor belts behind the Lifting table arranged between the two conveyor belts and rotatable about a horizontal axis of the transfer unit, which is designed as a cyclic impeller driven by a motor or 180 ° rotating cylinder and which supports the individual S between the two conveyor belts on their lateral surface takes up the coil and implements it by rotating its horizontal axis and opens it again with an end face of the coil takes off the conveyor belt.

Ein um eine Vertikalachse drehbarer auf- und abbewegbarer Hubtisch ist in Verbindung mit einer ansonsten anders gestalteten Spulenumsetzstation bereits in der EP 0 386 339 A1 beschrieben. Ein Flügelrad zur Übergabe bzw. Förderung von Spulen zwischen zwei in vertikalem Abstand laufenden Förderelementen ist in der EP 0 379 600 A1 behandelt.A lifting table that can be moved up and down about a vertical axis is already described in EP 0 386 339 A1 in connection with an otherwise differently designed coil transfer station. An impeller for transferring or conveying coils between two conveyor elements running at a vertical distance is dealt with in EP 0 379 600 A1.

Weiterbildungen der Erfindung sind in den Unteransprüchen behandelt.Further developments of the invention are dealt with in the subclaims.

Die Erfindung wird im folgenden anhand der Zeichnung näher beschrieben. Es zeigen:

  • Fig. 1 eine schematische perspektivische Ansicht der erfindungsgemäßen Vorrichtung;
  • Fig. 2 teilweise im Schnitt eine Ansicht des erfindungsgemäß verwendeten Hubtisches, und
  • Fig. 3 eine perpektivische Seitenansicht des erfindungsgemäß verwendeten Umsetzaggregates.
The invention is described below with reference to the drawing described in more detail. Show it:
  • Figure 1 is a schematic perspective view of the device according to the invention.
  • Fig. 2 is a partial sectional view of the lifting table used in the invention, and
  • Fig. 3 is a perspective side view of the transfer unit used in the invention.

Fig. 1 zeigt ausschnittsweise eine von einer vorhergehenden Bearbeitungsstufe kommende, beispielsweise endlose Förderschiene 1, entlang der beispielsweise mittels einer nicht dargestellten, innerhalb der Förderschiene 1 geführten Endloskette angetriebene Spulenförderelemente in Form von Spulenkörben 2 verfahrbar sind. Der einzelne Spulenkorb 2 kann beispielsweise aus Drahtelementen bestehen und ist so gestaltet, daß die einzelne Spule 3 entlang von Mantellinien in dem seitlich offenen Spulenkorb abgestützt ist. Anstelle von entlang der Förderschiene geführten Spulenkörben könnte auch ein endloses, muldenförmiges Transportband verwendet werden.1 shows a detail of an endless conveyor rail 1 coming from a previous processing stage, along which, for example, coil conveyor elements in the form of coil baskets 2 driven by means of an endless chain (not shown) guided within the conveyor rail 1 can be moved. The individual coil basket 2 can consist, for example, of wire elements and is designed such that the individual coil 3 is supported along surface lines in the laterally open coil basket. Instead of bobbins running along the conveyor rail, an endless, trough-shaped conveyor belt could also be used.

Unterhalb der Förderschiene 1 ist als Teilaggregat der erfindungsgemäßen Vorrichtung eine Übergabestation 4 angeordnet, die ein Maschinengestell 5 und einen an der Oberseite des Maschinengestells 5 gelagerten Schieber 6 aufweist, der mittels eines mit Druckmittel beaufschlagbaren Hubzylinders 7 in Richtung des Pfeiles f1 senkrecht zur Bewegungsrichtung der Spulenkörbe 2 hin und her bewegbar ist. Der Hubzylinder 7 ist über eine Druckmittelleitung 8 mit Druckmittel beaufschlagbar, und der Schieber 6 ist am vorderen Ende der Kolbenstange 9 des Hubzylinders 7 befestigt. Dem Schieber 6 ist ein Sensor 10, beispielsweise in Form einer optischen Zelle zugeordnet, um festzustellen, wann ein mit einer Spule 3 beladener Spulenkorb 2 in den Bereich der Übergabestation 4 eingefahren ist. An der Oberseite des Maschinengestells 5 ist eine Arretiereinrichtung gelagert, die vorzugsweise einen doppelarmigen Schwenkhebel 11 umfaßt , an dessen einem Ende ein mit Druckmittel beaufschlagbarer Hubzylinder 12 angreift, während das andere Schwenkhebelende ein gegen den Spulenkorb 2 zur Anlage bringbares Arretierelement 13 trägt. Der doppelarmige Schwenkhebel 11 ist in Richtung des Doppelpfeiles f2 verschwenkbar, um dann, wenn mittels des Sensors 10 festgestellt worden ist, daß in die Übergabestation 4 eine Spule 11 eingefahren ist, den Spulenkorb 2 in einer für eine Spulenübergabe geeigneten Lage zu positionieren und festzuhalten.Below the conveyor rail 1, a transfer station 4 is arranged as a sub-assembly of the device according to the invention, which has a machine frame 5 and a slide 6 mounted on the top of the machine frame 5, which by means of a lifting cylinder 7 which can be pressurized with pressure medium in the direction of arrow f1 perpendicular to the direction of movement of the bobbin baskets 2 is movable back and forth. The lifting cylinder 7 can be acted upon by a pressure medium line 8 with pressure medium, and the slide 6 is at the front end of the piston rod 9 of the lifting cylinder 7 attached. A sensor 10, for example in the form of an optical cell, is assigned to the slide 6 in order to determine when a bobbin 2 loaded with a bobbin 3 has entered the area of the transfer station 4. At the top of the machine frame 5, a locking device is mounted, which preferably comprises a double-armed pivot lever 11, at one end a lifting cylinder 12 which can be acted upon by pressure medium engages, while the other end of the pivot lever carries a locking element 13 which can be brought into abutment against the bobbin basket 2. The double-armed pivot lever 11 can be pivoted in the direction of the double arrow f2, in order to position and hold the bobbin 2 in a position suitable for a bobbin transfer when it has been determined by means of the sensor 10 that a bobbin 11 has entered the transfer station 4.

Die Übergabestation 4 enthält weiterhin eine Spulenleitfläche 14, die so angeordnet ist, daß mittels des Schiebers 6 aus den einzelnen Spulenkörben 2 herausgedrückte Spulen 3 über diese Leitfläche 14 auf eine Fördereinrichtung rollen, die durch zwei angetriebene, endlose und im Abstand voneinanderliegende Förderriemen 15 gebildet ist. Die beiden Förderriemen 15 können beispielsweise Rundriemen sein und laufen über geeignte Rollenpaare 16 und 17, von denen eines angetrieben ist. Die Förderriemen 15 sind zumindest teilweise in den Bereichen, in denen eine Spulenförderung erfolgt, von Stützschienen 18 abgestützt. Oberhalb der Förderriemen 15 sind Leitschienen 19 zum seitlichen Abstützen der von Förderriemen 15 bewegten Spulen angeordnet.The transfer station 4 also contains a coil guide surface 14, which is arranged such that coils 3 pressed out of the individual coil baskets 2 by means of the slider 6 roll over this guide surface 14 onto a conveyor device, which is formed by two driven, endless and spaced apart conveyor belts 15 . The two conveyor belts 15 can, for example, be round belts and run over suitable pairs of rollers 16 and 17, one of which is driven. The conveyor belts 15 are at least partially supported by support rails 18 in the areas in which a coil is conveyed. Above the conveyor belt 15 are guide rails 19 for lateral support the coils moved by conveyor belts 15.

Zwischen den beiden Förderriemen 15 ist ein um eine Vertikalachse drehbarer Hubtisch 20 auf- und abbewegbar, dem eine geeignete Dreheinrichtung 21 und eine Hubeinrichtung 21a zugeordnet sind, die beide vorzugsweise von einer Druckmittelquelle 40 mit Druckmittel beaufschlagbar sind.Between the two conveyor belts 15, a lifting table 20 rotatable about a vertical axis can be moved up and down, to which a suitable rotating device 21 and a lifting device 21a are assigned, both of which can preferably be acted upon by a pressure medium source 40 with pressure medium.

Auf diesen Hubtisch 20 folgt in der durch den Pfeil f3 repräsentierten Förderrichtung der Förderriemen 15 ein um eine Horizontalachse drehbares Umsetzaggregat, welches vorzugsweise die Form eines Flügelrades 22 hat. Ein Motor 23 oder ein 180° -Drehzylinder mit Freilauf und Bremse und Index-Rastbolzen dient zum taktweisen Antrieb des Flügelrades 22.This lifting table 20 is followed in the conveying direction represented by the arrow f3 of the conveyor belt 15 by a transfer unit which can be rotated about a horizontal axis and which preferably has the shape of an impeller 22. A motor 23 or a 180 ° rotating cylinder with freewheel and brake and index locking bolt is used to drive the impeller 22 in cycles.

In Bewegungsrichtung der beiden Förderriemen 15 folgt auf das Flügelrad 22 eine Spulenabnahmestation, die entweder durch die Förderriemen 15 selbst, durch eine nicht dargestellte Tischfläche oder eine weitere Fördereinrichtung gebildet sein kann, an die die entsprechend umgesetzten Spulen von den Förderriemen 12 weitergegeben werden.In the direction of movement of the two conveyor belts 15, the impeller 22 is followed by a bobbin removal station, which can be formed either by the conveyor belts 15 themselves, by a table surface (not shown) or by a further conveyor device, to which the correspondingly converted bobbins are passed on by the conveyor belts 12.

Sobald ein mit einer Spule 3 beladener Spulenkorb 2 in den Bereich der Übergabestation 4 eingefahren und mittels der insbesondere von dem Sensor 10 gesteuerten Arretiereinrichtung 11, 12, 13 arretiert worden ist, wird der Schieber 6 mittels des Hydraulikzylinders 7 betätigt und in Richtung des Pfeiles f1 vorwärts geschoben, um die Spule 3 über die Leitfläche 14 auf die durch die beiden Förderriemen 15 gebildete endlose Fördereinrichtung zu rollen. Die entweder taktweise oder kontinuierlich angetriebenen Förderriemen 15 fördern die Rolle 3 dann in den Bereich des Hubtisches 20 dem in Abhängigkeit von der vorher ermittelten Lage der Spule 3 ein Steuerbefehl zugeleitet wird, um die Spule 3 gegebenenfalls von dem Förderriemen 15 abzuheben und in Richtung des Drehpfeiles f4 um 180° zu drehen und dann wieder auf die Förderriemen 15 abzulegen. Die so gewendete Spule 3 wird dann bei der Weiterförderung an das das Umsetzaggregat bildende Flügelrad 22 übergeben, das dazu dient, die vorher mit horizontal ausgerichteter Spulenachse geförderte Spule 3 in eine solche Position umzusetzen, daß die Spulenachse abschließend eine vertikale Position einnimmt, wie es in Figur 3 anhand der Spule 3' dargestellt ist.As soon as a bobbin 2 loaded with a bobbin 3 has been moved into the area of the transfer station 4 and locked by means of the locking device 11, 12, 13, in particular controlled by the sensor 10, the slide 6 is actuated by means of the hydraulic cylinder 7 and in the direction of arrow f1 pushed forward to the coil 3 over the guide surface 14 on by the two Conveyor belt 15 formed endless conveyor to roll. The conveyor belts 15, which are driven either cyclically or continuously, then convey the roller 3 into the region of the lifting table 20, to which a control command is sent as a function of the previously determined position of the bobbin 3, in order to lift the bobbin 3 from the conveyor belt 15, if necessary, and in the direction of the rotary arrow turn f4 by 180 ° and then put it back on the conveyor belt 15. The coil 3 thus turned is then passed on during further conveyance to the impeller 22 forming the transfer unit, which serves to convert the coil 3 previously conveyed with a horizontally oriented coil axis into such a position that the coil axis finally assumes a vertical position, as shown in FIG Figure 3 is shown with reference to the coil 3 '.

Die so in die vorgeschriebene Position gewendete Spule kann anschließend von den Förderriemen abgehoben oder an eine nicht dargestellte weitere Fördereinrichtung übergeben werden.The coil thus turned into the prescribed position can then be lifted off the conveyor belt or transferred to a further conveyor device, not shown.
