Abstract

Das Ansetzen von umfänglichen und deshalb schwergewichtigen Bobinen (Wickelrollen) aus Verpackungsmaterial an Verpackungsmaschinen ist für das Bedienungspersonal eine belastende Tätigkeit. Durch ein mechanisches Hubgetriebe, das von einem Handhebel leicht zu bedienende Halteorgane für die Bobine aufweist, ist diese ohne Kraftaufwand in die Arbeitsposition an der Verpackungsmaschine zu bringen. Die Halterung ist so ausgebildet, daß die Bobine spindelfrei (also ohne Achsstange) gelagert ist.

The application of extensive and therefore heavy-weight bobbins (winding rolls) made of packaging material to packaging machines is a stressful task for the operating personnel. A mechanical lifting gear, which has easy-to-use holding elements for the bobbin, can be brought into the working position on the packaging machine without effort. The bracket is designed so that the bobbin is spindle-free (i.e. without an axle rod).

Description

Die Erfindung betrifft eine Halterung für Bobinen (Wickelrollen) aus Verpackungsmaterial an Verpackungsmaschinen u. dgl. , wobei die Bobine eine mittige Öffnung für den Anschluß der Halterung aufweist und durch diese von einer Unterlage (Boden) abhebbar sowie in Arbeitsstellung bewegbar ist.The invention relates to a holder for bobbins (winding rolls) made of packaging material on packaging machines and. Like., The bobbin has a central opening for the connection of the bracket and can be lifted by this from a base (floor) and movable in the working position.

Bei einer Vielzahl von Verpackungsmaschinen werden die zu verarbeitenden Zuschnitte unmittelbar durch die Verpackungsmaschine durch Abtrennen von einer Bahn des Verpackungsmaterials hergestellt. Dies gilt insbesondere für verhältnismässig dünnwandiges Verpackungsmaterial, das von einer Bobine, also einer Rolle des Verpackungsmaterials abgezogen wird. Bei Verpackungsmaterial mit hohem Eigengewicht und/oder bei der Herstellung großvolumiger Packungen mit entsprechendem Bedarf an Verpackungsmaterial sind die den Verpackungsmaschinen zuzustellenden Bobinen entsprechend groß .dimensioniert und folglich schwergewichtig.In the case of a large number of packaging machines, the blanks to be processed are produced directly by the packaging machine by cutting off a web of the packaging material. This applies in particular to relatively thin-walled packaging material which is pulled off a reel, that is to say a roll of the packaging material. With packaging material with a high weight and / or with the Manufacture of large-volume packs with a corresponding need for packaging material, the bobbins to be delivered to the packaging machines are correspondingly large .dimensioned and consequently heavy.

Es ist bekannt, durch die zentrische, durchgehende Öffnung der Bobine eine Achse als Tragorgan hindurchzuführen. Die seitlich überstehenden Enden dieser Achse werden durch eine hydraulische Hubeinrichtung erfaßt, die durch Anheben der Achse die Bobine in eine Arbeitsstellung bewegt. In dieser Position liegt die Achse mit ihren Enden in einem am Maschinengestell gebildeten Lager. Das Verpackungsmaterial kann nunmehr von der drehbaren Bobine abgezogen werden. Die vorstehende bekannte Einrichtung ist in der Herstellung aufwendig , und im Betrieb störanfällig, da mindestens zwei druckmittelbeaufschlagte Hubzylinder erforderlich sind, die synchron bewegt werden müssen.It is known to pass an axis as a supporting member through the central, continuous opening of the bobbin. The laterally projecting ends of this axle are gripped by a hydraulic lifting device which moves the bobbin into a working position by lifting the axle. In this position, the ends of the axis lie in a bearing formed on the machine frame. The packaging material can now be removed from the rotating bobbin. The above known device is complex to manufacture and susceptible to failure in operation, since at least two lifting cylinders pressurized with pressure medium are required, which must be moved synchronously.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, eine Halterung für Bobinen im Zusammenhang mit Verpackungsmaschinen u. dgl. vorzuschlagen, die im Aufbau vereinfacht, dennoch leicht zu handhaben ist und zuverlässig arbeitet.The invention is therefore based on the object, a holder for bobbins in connection with packaging machines and. Propose the like, which is simplified in construction, yet easy to use and works reliably.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Halterung dadurch gekennzeichnet, daß zwei seitlich angreifende Halteorgane (Klemmbacken) durch ein Hubgetriebe in aufeinanderfolgenden Bewegungsphasen in Eingriff mit der Bobine bewegbar und mit dieser anhebbar sind.To achieve this object, the holder according to the invention is characterized in that two laterally engaging holding members (clamping jaws) can be moved into engagement with the bobbin by a lifting gear in successive movement phases and can be raised with it.

Die erfindungsgemäße Halterung hat demnach eine Doppelfunktion, indem sie die Bobine von einer Lagerfläche, insbesondere vom Boden aufnimmt, in die Arbeitsstellung fördert und in dieser für den Abzug des Verpackungsmaterials hält. Die Bobine wird dabei in der Arbeitsstellung drehbar auf den Halteorganen gelagert.The holder according to the invention therefore has a double function in that it picks up the bobbin from a bearing surface, in particular from the floor, into the working position and into it holds for the deduction of the packaging material. The bobbin is rotatably mounted on the holding members in the working position.

Vorzugsweise sind die beweglichen Organe des Hubgetriebes ausschließlich mechanisch ausgebildet und durch einen manuell zu bedienenden Betätigungshebel bewegbar. Dieser ist in Verbindung mit einem Hubgetriebe so ausgebildet, daß mit einem geringen Kraftaufwand sowohl die Bobine erfaßbar und anschließend in die Arbeitsstellung hebbar ist.The movable members of the lifting gear are preferably designed exclusively mechanically and can be moved by a manually operated actuating lever. This is designed in connection with a lifting gear so that both the bobbin can be grasped with little effort and then lifted into the working position.

Nach einem weiteren Merkmal der Erfindung ist die Halterung mit Klemmbacken ausgerüstet, die an schwenk- und hebbaren Tragarmen angeordnet und in kraft- bzw. formschlüssige Verbindung mit der Bobine bewegbar sind. Die Tragarme werden durch ein Hubgetriebe derart bewegt, daß während einer ersten Bewegungsphase die Klemmbacken in Eingriff mit der Bobine bewegt und dann unter Fortsetzung der Bewegung die Tragarme zusammen mit der aufgenommenen Bobine angehoben werden.According to a further feature of the invention, the holder is equipped with clamping jaws which are arranged on pivotable and liftable support arms and can be moved in a non-positive or positive connection with the bobbin. The support arms are moved by a lifting mechanism in such a way that the clamping jaws are moved into engagement with the bobbin during a first movement phase and the support arms are then lifted together with the taken-up bobbin while continuing the movement.

Nach dem Eingriff der Klemmbacken mit der Öffnung der Bobine erfolgt bei fortgesetzter Betätigung des Hubgetriebes eine Verlagerung von Getriebeorganen derart, daß bei Aufrechterhaltung des Eingriffs der Klemmbacken diese mit der Bobine aufwärtsbewegt werden.After the engagement of the clamping jaws with the opening of the bobbin, with continued actuation of the lifting gear, there is a displacement of gear elements in such a way that, while the engagement of the clamping jaws is maintained, these are moved upwards with the bobbin.

Das erfindungsgemäße Getriebe ist wenig störanfällig, hochbelastbar und im Sinne von Übersichtlichkeit einfach.The transmission according to the invention is less susceptible to malfunction, can withstand high loads and is simple in the sense of clarity.

Weitere Merkmale der Erfindung sind Gegenstand von Unteransprüchen.Further features of the invention are the subject of dependent claims.

Ein Ausführungsbeispiel der erfindungsgemäßen Halterung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:

  • Fig. 1 eine Halterung für eine Bobine in Verbindung mit einer schematisch dargestellten Verpackungsmaschine,
  • Fig. 2 die Halterung als Einzelheit in Vorderansicht bei Aufnahme einer Bobine,
  • Fig. 3 die Halterung gemäß Fig. 2 mit an die Bobine angekuppelten Tragorganen,
  • Fig. 4 die Halterung gemäß Fig. 2 und 3 mit der Bobine in ihrer End- bzw. Arbeitsstellung,
  • Fig. 5 eine Seiten- bzw. Queransicht der Halterung.
An embodiment of the holder according to the invention is explained in more detail with reference to the drawings. Show it:
  • 1 is a holder for a bobbin in connection with a schematically illustrated packaging machine,
  • 2 the holder as a detail in front view when taking a bobbin,
  • 3 shows the holder according to FIG. 2 with supporting elements coupled to the bobbin,
  • 4 the holder according to FIGS. 2 and 3 with the bobbin in its end or working position,
  • Fig. 5 is a side or transverse view of the bracket.

In Fig. 2 bis 4 ist ein Ausführungsbeispiel einer Halterung zur Aufnahme und Lagerung einer Bobine 10 als Einzelheit in verschiedenen Positionen dargestellt. Diese Halterung ist hier mit einem Träger in Gestalt einer Tragplatte 11 an einer schematisch dargestellten Verpackungsmaschine 33 bzw. an deren Maschinengestell angebracht. In angehobener (Arbeits-)Stellung wird eine Bahn 34 Verpackungsmaterial von der Bobine 10 abgezogen.2 to 4, an embodiment of a holder for receiving and storing a bobbin 10 is shown as a detail in different positions. This holder is attached with a carrier in the form of a support plate 11 to a schematically illustrated packaging machine 33 or to its machine frame. In the raised (working) position, a web 34 of packaging material is pulled off the bobbin 10.

Die Bobine 10 befindet sich bei Übernahme durch die Halterung bzw. durch die Verpackungsmaschine 33 auf einer Unterlage, im vorliegenden Fall auf dem Boden 12. Die Bobine 10 ist mit einer mittig verlaufenden, durchgehenden Öffnung 13 versehen. Diese wird im vorliegenden Fall zum Ansetzen der Halterung benutzt. In die beiden Enden der Öffnung 13 treten Klemmbacken 14 und 15 mit einem Konus 16 kraft- und formschlüssig ein.When taken over by the holder or by the packaging machine 33, the bobbin 10 is on a base, in the present case on the floor 12. The bobbin 10 is provided with a central, continuous opening 13. These is used in the present case to attach the bracket. In the two ends of the opening 13, jaws 14 and 15 enter with a cone 16 in a non-positive and positive manner.

Die Klemmbacken 14 und 15 sind verstellbar und drehbar, nämlich um die durch die Öffnung 13 verlaufende Längsachse, am unteren, freien Ende jeweils eines Tragarms 17 und 18 angeordnet. Durch diese Lagerung der Klemmbacken 14,15 ist die Bobine 10 drehbar an den Tragarmen 17 und 18 gelagert. Diese sind hier bügelförmig ausgebildet und umfassen von oben her die Bobine 10, derart, daß sich die Klemmbacken 14, 15 in Höhe der Öffnung 13 befinden.The clamping jaws 14 and 15 are adjustable and rotatable, namely about the longitudinal axis running through the opening 13, at the lower, free end of a support arm 17 and 18, respectively. As a result of this mounting of the clamping jaws 14, 15, the bobbin 10 is rotatably mounted on the support arms 17 and 18. These are bow-shaped here and include the bobbin 10 from above, such that the clamping jaws 14, 15 are located at the level of the opening 13.

In der Ausgangsstellung (Fig. 2) sind die Tragarme 17, 18 seitlich zurückgeschwenkt, so daß sie mit den Klemmbacken 14, 15 von oben her über die Bobine 10 abgesenkt werden können. Sodann werden die beiden Tragarme 17, 18 im gegenläufigen Sinne verschwenkt, wodurch die Klemmbacken 14 und 15 mit der Öffnung 13 in Eingriff gelangen (Fig. 3). Bei weiterer Betätigung der Halterung werden in einem stufenlosen Bewegungsablauf die Tragarme 17 und 18 aufwärtsbewegt unter Mitnahme der Bobine 10 in deren Arbeitsstellung gemäß Fig. 4.In the starting position (Fig. 2), the support arms 17, 18 are pivoted back laterally, so that they can be lowered with the clamping jaws 14, 15 from above over the bobbin 10. The two support arms 17, 18 are then pivoted in the opposite direction, as a result of which the clamping jaws 14 and 15 come into engagement with the opening 13 (FIG. 3). When the holder is actuated further, the support arms 17 and 18 are moved upwards in a stepless movement, taking the bobbin 10 into its working position according to FIG. 4.

Zur Durchführung der vorgenannten Bewegung werden die Tragarme 17, 18 bei dem vorliegenden Ausführungsbeispiel durch ein mechanisches Hubgetriebe 19 beaufschlagt. Zu diesem gehören zwei drehbar an der Tragplatte 11 gelagerte Zahnräder 20 und 21, die miteinander in Eingriff stehen. Die Zahnräder 20, 21 werden gemeinsam hin- und hergedreht, und zwar durch einen Betätigungshebel 22, der auf das Zahnrad 20 einwirkt.To carry out the aforementioned movement, the support arms 17, 18 are acted upon in the present exemplary embodiment by a mechanical lifting gear 19. This includes two gears 20 and 21 which are rotatably mounted on the support plate 11 and which are in engagement with one another. The gears 20, 21 are rotated back and forth together, namely by an actuating lever 22 which acts on the gear 20.

Der Betätigungshebel 22 soll hier von Hand bedient werden und ist zur Übertragung einer ausreichenden Kraft entsprechend lang bemessen.The actuating lever 22 is to be operated here by hand and is dimensioned accordingly long to transmit a sufficient force.

Die dem Hubgetriebe 19 zugekehrten Enden der Tragarme 17 und 18 sind in einem Gelenk 23, 24 mit je einer Hublasche 25 und 26 schwenkbar verbunden. Die Hublaschen 25, 26 sind ihrerseits über Drehlager 27, 28 an die Zahnräder 20, 21 angekuppelt, und zwar in bestimmter Relativstellung, derart, daß die Drehlager 27, 28 in der Ausgangsstellung (Fig. 2) nach unten und in der entgegengesetzten Endstellung (Fig. 4) im wesentlichen nach oben gerichtet sind.The ends of the support arms 17 and 18 facing the lifting gear 19 are pivotably connected in a joint 23, 24, each with a lifting bracket 25 and 26. The lifting brackets 25, 26 are in turn coupled to the gears 20, 21 via rotary bearings 27, 28, in a certain relative position such that the rotary bearings 27, 28 are in the starting position (FIG. 2) downwards and in the opposite end position ( Fig. 4) are directed essentially upwards.

Die Tragarme 17, 18 sind mittelbar mit der Tragplatte 11 verbunden, und zwar über Stützlaschen 29, 30. Diese sind jeweils gelenkig mit den Tragarmen 17, 18 verbunden, und zwar in einem von den Gelenken 23, 24 bzw, den Enden der Tragarme 17, 18 abliegenden Bereich. Die anderen Enden der Stützlaschen 29, 30 sind im unteren Bereich der Tragplatte 11 mit dieser schwenkbar verbunden.The support arms 17, 18 are indirectly connected to the support plate 11, specifically via support brackets 29, 30. These are each articulated to the support arms 17, 18, namely in one of the joints 23, 24 or the ends of the support arms 17th , 18 remote area. The other ends of the support tabs 29, 30 are pivotally connected to the support plate 11 in the lower region thereof.

In der Ausgangsstellung der Halterung gemäß Fig. 2 befinden sich die Hublaschen 25, 26 aufgrund entsprechender Relativstellung der Zahnräder 20, 21 in ihrer unteren Endstellung. Entsprechend sind die mit diesen Hublaschen 25, 26 verbundenen Enden der Tragarme 17, 18 nach unten verschwenkt. Die Stützlaschen 29,30 sind etwa horizontal gerichtet. Diese Ausgangsstellung des Hubgetriebes 19 wird durch ein Stützorgan in Gestalt einer Knagge 31 gehalten, die etwa mittig zwischen den Hublaschen 25, 26 an der Tragplatte 11 angebracht ist und an der die Hublaschen 25, 26 anliegen.2, the lifting tabs 25, 26 are in their lower end position due to the corresponding relative position of the gears 20, 21. Accordingly, the ends of the support arms 17, 18 connected to these lifting brackets 25, 26 are pivoted downward. The support tabs 29, 30 are directed approximately horizontally. This starting position of the lifting gear 19 is held by a support member in the form of a lug 31, which is attached approximately centrally between the lifting brackets 25, 26 on the support plate 11 and against which the lifting brackets 25, 26 rest.

Eine Schwenkbewegung des in Ausgangsstellung quer abstehenden Betätigungshebels 22 in eine Stellung gemäß Fig. 3 bei entsprechender Drehung der Zahnräder 20, 21 bewirkt ein Anheben der Hublaschen 25, 26 und mit ihnen der zugekehrten Enden der Tragarme 17, 18. Die Stützlaschen 29, 30 bleiben dabei im wesentlichen in der Ausgangsstellung lt. Fig. 2.A pivoting movement of the actuating lever 22 projecting transversely in the starting position into a position according to FIG. 3 with a corresponding rotation of the gear wheels 20, 21 causes the lifting Lifting tabs 25, 26 and with them the facing ends of the support arms 17, 18. The support tabs 29, 30 remain essentially in the starting position according to FIG. 2.

Die vorgenannte erste Bewegungsphase hat zur Folge, daß die Tragarme 17, 18 im Uhrzeiger- bzw. Gegenuhrzeigersinn verschwenkt werden bis zum Eingriff der Klemmbacken 14, 15 mit der Bobine 10.The aforementioned first movement phase has the result that the support arms 17, 18 are pivoted clockwise or counterclockwise until the jaws 14, 15 engage with the bobbin 10.

Bei weiterer Bewegung des Betätigungshebels 22 bis in die Stellung gemäß Fig. 4 werden die Hublaschen 25, 26 bis zu ihrer oberen Endstellung im wesentlichen aufwärtsbewegt, nämlich bis zur Anlage aneinander. Während dieser Bewegungsphase führen die Tragarme 17, 18 infolge der Abstützung durch die Stützlaschen 29, 30 im wesentlichen eine translatorische Aufwärtsbewegung durch unter Mitnahme, also unter Anheben der Bobine 10. Die Stützlaschen 29, 30 werden dabei ebenfalls gegenläufig verschwenkt.When the actuating lever 22 is moved further into the position according to FIG. 4, the lifting tabs 25, 26 are moved essentially upwards to their upper end position, namely until they come into contact with one another. During this movement phase, the support arms 17, 18 essentially carry out a translatory upward movement as a result of the support by the support straps 29, 30, while taking the bobbin 10 with them, ie while lifting them. The support straps 29, 30 are also pivoted in opposite directions.

Die voranstehend geschilderten Endpositionen gemäß Fig. 2 und 4 werden durch eine in ihrer Wirkung umspringende Belastung des Getriebes in der einen und anderen Richtung fixiert. Im vorliegenden Fall ist eine Zugfeder 32 mit einem Ende an der Tragplatte 11 und mit dem anderen Ende am Drehlager 27 für die Hublasche 25 befestigt. Die Federkraft wirkt aufgrund der gewählten Relativstellungen jeweils in Richtung auf die Endpositionen des Hubgetriebes 19. Etwa in der Stellung gemäß Fig. 3 wird eine Totpunktstellung überschritten.The above-described end positions according to FIGS. 2 and 4 are fixed in one and the other direction by a load on the transmission that changes in effect. In the present case, a tension spring 32 is attached at one end to the support plate 11 and at the other end to the pivot bearing 27 for the lifting tab 25.
