Description

Die Erfindung betrifft eine Umreifungsvorrichtung für Packstücke, in welcher eine Anordnungseinrichtung ein Kantenschutzmittel vor dem Umreifungsvorgang am Packstück anordnet und das Kantenschutzmittel von einem Umreifungsmittel nach dem Umreifungsvorgang am Packstück gehalten ist, wobei ein Vortrieb das Kantenschutzmittel von einem Magazin zur Anordnungseinrichtung bewegt.The invention relates to a strapping device for packages in which an arrangement means an edge protection means prior to the strapping process on the package and the edge protection means is held by a strapping after Umreifungsvorgang the package, wherein a propulsion moves the edge protection means from a magazine to the arrangement means.

Eine gattungsgemäße Vorrichtung ist beispielweise in DE 30 25 825 A1 offenbart.A generic device is for example in DE 30 25 825 A1 disclosed.

Vorrichtungen zum Umreifen von Packstücken verfügen in der Regel über einen sogenannten Packtisch, auf welchem ein zu umreifendes Packstück in der Vorrichtung aufliegt. An dem Packtisch ist ein Führungsrahmen angeordnet, der das Packstück umgibt und innerhalb dessen ein Umreifungsmittel, wie beispielsweise ein thermoplastisches Band, ausgehend von einer Spann- und Verschlussvorrichtung um das Packstück geführt wird. Beim Wiedererreichen der Spann- und Verschlussvorrichtung wird das freie Ende des Umreifungsmittels gehalten und das Umreifungsmittel durch einen teilweisen Rückzug um das Packstück gespannt. Dabei wird das Umreifungsmittel aus dem Führungsrahmen herausgezogen. Um dies zu ermöglichen, weist der Führungsrahmen an seinen zum Packstück gewandten Seiten geeignete Rückhaltemittel auf, wie zu öffnende Klappen, Bürstenvorsätze oder Ähnliches. Beim Spannen des Umreifungsmittels um das Packstück übt dieses insbesondere an den Packstückkanten hohe Kräfte aus, die zur Beschädigung des Packstückes führen können. So ist es beispielsweise bekannt, dass das Umreifungsmittel Kartonagen an den Kanten eindrückt oder einschneidet. Je nach Packstückart und -güte ist dies unerwünscht. Um derartige Beschädigungen zu vermeiden, werden Packstücke vor dem Umreifungsvorgang mit Kantenschutzmitteln versehen. Hierbei handelt es sich in der Regel um plattenartige Kartonagen, die an den zu schützenden Kanten angelegt werden und vom Umreifungsmittel am Packstück gehalten sind.Devices for strapping packages usually have a so-called packing table, on which rests a package to be strapped in the device. Arranged on the packing table is a guide frame which surrounds the package and within which a strapping means, such as a thermoplastic band, is guided around the package starting from a tensioning and closing device. Upon re-reaching the tightening and locking device, the free end of the strap is held and the strap is tensioned by a partial withdrawal around the package. The strap is pulled out of the guide frame. To make this possible, the guide frame on its sides facing the package suitable retaining means, such as opening flaps, brush attachments or the like. When tensioning the strapping around the package exerts this particular on the package edges high forces that can lead to damage to the package. Thus, it is known, for example, that the strapping material presses or cuts cardboard at the edges. Depending on the package type and quality, this is undesirable. To avoid such damage, packages are provided with edge protectants before the strapping process. These are usually plate-like cardboard, which are applied to the edges to be protected and are held by the strap on the package.

Die Kantenschutzmittel werden gewöhnlich in einem Magazin vorgehalten und von dort über einen Vortrieb an die Anordnungseinrichtung übergeben, die das Kantenschutzmittel am Packstück positioniert.The edge protection means are usually held in a magazine and passed from there via a drive to the assembly device, which positions the edge protection means on the package.

Aus dem druckschriftlich nicht belegbaren Stand der Technik ist es bekannt, dass Entnahmewerkzeuge an einer der in Förderrichtung hinteren Schmalkanten des plattenartigen Kantenschutzmittels angreifen und dieses zur Anordnungseinrichtung hin schieben. Auch ist es bekannt, dass Bänder an einer der zur Anlage am Packstück vorgesehenen Hauptflächen des Kantenschutzmittels reibschlüssig anliegen und der Reibschluss bei Bewegung des Bandes ausreichend ist, um das Kantenschutzmittel in Richtung Anordnungseinrichtung zu fördern.It is known from the prior art document which can not be assigned that removal tools engage one of the rear narrow edges of the plate-like edge protection means in the conveying direction and push it towards the arrangement device. It is also known that ribbons rest frictionally on one of the main surfaces of the edge protection means provided for attachment to the package, and the frictional engagement with movement of the band is sufficient to convey the edge protection means in the direction of the arrangement device.

Beide Vortriebe haben mit dem Problem zu kämpfen, dass die aus dem Magazin nachrückenden Kantenschutzmittel ebenfalls eine Kraft auf das zur Entnahme vorgesehene Kantenschutzmittel ausüben, was zu Fehlentnahmen führen kann.Both advances have to contend with the problem that the edge protection means advancing from the magazine also exert a force on the edge protection means provided for removal, which can lead to erroneous picking.

Aus US 1,770,099 A ist es bekannt, Briefe auf ihrer Schmalseite durch einen Transportkanal auf einen umlaufenden Band zu befördern. DE 1 200 212 B zeigt eine ähnliche Einrichtung.Out US 1,770,099 A It is known to convey letters on their narrow side through a transport channel on a circulating belt. DE 1 200 212 B shows a similar device.

Aufgaben der Erfindung ist es, einen neuartigen Vortrieb für einen Kantenschutzmittel bereitzustellen, der Fehlentnahmen sicher verhindert. Gelöst wird die Aufgabe von einer Umreifungsvorrichtung mit den Merkmalen des Anspruches 1, insbesondere mit den kennzeichnenden Merkmalen, wonach der Vortrieb ein endlos umlaufendes Fördermittel umfasst, auf welchem das Kantenschutzmittel aufsitzt, und dass der für die Vortriebbewegung notwendige Reibschluss zwischen Fördermittel und Kantenschutzmittel durch das Eigengewicht des Kantenschutzmittels hervorgerufen ist, wobei der Vortrieb Teil einer Schiene ist, die in Förderrichtung aus dem Magazin ausfahrbar ist.Objects of the invention is to provide a novel propulsion for an edge protection means that reliably prevents misappropriation. The object is achieved by a strapping device with the features of claim 1, in particular with the characterizing features, according to which the propulsion comprises an endlessly circulating conveyor, on which the edge protection means is seated, and that the necessary for the propulsion movement frictional engagement between the conveyor and edge protection means by its own weight the edge protection means is caused, wherein the propulsion part of a rail which is extendable in the conveying direction from the magazine.

Dabei ist insbesondere vorgesehen, dass das auf dem Fördermittel aufliegende Kantenschutzmittel aus dem im Magazin gebildeten Kantenschutzmittelverbund herausgelöst ist.In this case, provision is made in particular for the edge protection means resting on the conveyor to be released from the edge protection agent compound formed in the magazine.

Die Erfindung macht sich zunächst die Tatsache zu nutze, dass die Gewichtskraft des Kantenschutzmittels prinzipiell ausreichend ist, um einen ausreichenden Reibschluss zum Fördermittel aufzubauen, und so einfach und unkompliziert an die Anordnungseinrichtung übergeben werden kann, sofern keine anderen, dem Reibschluss entgegenwirkenden Kräfte den Vortrieb des Kantenschutzmittels beeinflussen.The invention makes use first of all of the fact that the weight of the edge protection agent is in principle sufficient to build up sufficient frictional engagement with the conveyor, and can be handed over to the arrangement device in such a simple and uncomplicated manner, if no other forces counteracting the frictional engagement promote the propulsion of the device Influence edge protection agent.

Um solche Gegenkräfte sicher auszuschließen ist, wie vorerwähnt, in einer konkreten Ausführungsform vorgesehen, dass das Kantenschutzmittel zur Bewegung durch den Vortrieb aus dem Verbund herausgelöst ist, der von den im Magazin vorgehaltenen Kantenschutzmitteln gebildet ist. Das Herauslösen aus diesem Kantenschutzmittelverbund geschieht bevorzugt durch eine vorgeschaltete Vereinzelung.To safely exclude such opposing forces is, as mentioned above, provided in a specific embodiment, that the edge protection means is released from the composite for movement by the propulsion, which is formed by the edge protection means held in the magazine. The dissolving out of this edge protection agent compound is preferably done by an upstream separation.

Zur Übergabe des Kantenschutzmittels an eine Anordnungseinrichtung wird zunächst die Schiene in Förderrichtung bewegt werden, woran sich die eigentliche Ausförderung des Kantenschutzmittels über das Fördermittel und das Walzenpaar anschließt. Auf diese Weise können größere Distanzen zur Anordnungseinrichtung überbrückt werden.To transfer the edge protection means to an arrangement device, the rail will first be moved in the conveying direction, followed by the actual removal of the edge protection means via the conveying means and the pair of rollers. In this way, greater distances to the arrangement device can be bridged.

Es ist weiterhin vorgesehen, dass das Fördermittel bodenseitig in einem Kanalabschnitt angeordnet ist, dessen Kanalseitenwände der Lagestabilisierung des Kantenschutzmittels dienen.It is further provided that the conveyor is arranged on the bottom side in a channel section whose channel side walls serve to stabilize the position of the edge protection means.

Da das Kantenschutzmittel auf seinem Bewegungsweg zur Anordnungseinrichtung den lagestabilisierenden Kanalabschnitt verlässt, ist vorgesehen, dass der Vortrieb an seinem der Anordnungseinrichtung nahen Übergabeende zwei mit Abstand einander gegenüberliegende Rollen oder Walzen aufweist, zwischen denen das Kantenschutzmittel zur Übergabe an die Anordnungseinrichtung hindurchgeführt ist. Auf diese Weise ist die Lagestabilisierung auch bei Übergabe an die Anordnungseinrichtung gewährleistet.Since the edge protection means leaves the position-stabilizing channel section on its movement path to the arrangement device, it is provided that the drive has at its transfer end close to the arrangement device two rollers or rollers spaced apart from one another, between which the edge protection means is passed for transfer to the arrangement device. In this way, the position stabilization is ensured even when transferring to the device arrangement.

Deshalb ist vorgesehen, dass die Rollen oder Walzen zur Lagestabilisierung des Kantenschutzmittels während der Übergabe an das Anordnungsmittel dienen.Therefore, it is provided that the rollers or rollers serve to stabilize the position of the edge protection means during the transfer to the arrangement means.

Des Weiteren ist vorgesehen, dass die Rollen oder Walzen das Kantenschutzmittel reibschlüssig zwischen sich aufnehmen und zumindest eine Rolle oder Walze angetrieben ist, um das Kantenschutzmittel an die Anordnungseinrichtung zu übergeben.Furthermore, it is provided that the rollers or rollers receive the edge protection means frictionally between them and at least one roller or roller is driven in order to transfer the edge protection means to the arrangement device.

Dabei ist es denkbar, dass der Antrieb der Rolle oder Walze durch das als Treibriemen wirkende Fördermittel erfolgt.It is conceivable that the drive of the roller or roller is effected by acting as a drive belt conveyor.

Alternativ ist es denkbar, dass die angetriebene Rolle oder Walze als Antrieb für das Fördermittel dient.Alternatively, it is conceivable that the driven roller or roller serves as a drive for the conveyor.

Der wesentliche Vorteil beider vorgenannter Ausführungsformen ist, dass für den Gesamtvortrieb nur ein motorischer Antrieb vorzusehen ist, der sowohl Rolle bzw. Walze als auch das Fördermittel in Vortriebsbewegung versetzt.The main advantage of both aforementioned embodiments is that only a motor drive is to be provided for the total propulsion, the both roll or roller and the conveying means in propulsive motion.

Dargestellt ist der Vorratsbehälter 22, innerhalb dessen Kantenschutzmittel 13 in einem Stapel angeordnet sind. Das Magazin ist auf Stützen 23 gestellt und weist ein zum Betrachter der Figur 3 gewandtes Leitblech 18 auf, welches im Zusammenspiel mit einer in Figur 1 näher beschriebenen Förderfläche die plattenartigen Kantenschutzmittel 13 aus einer im Wesentlichen horizontalen Ausrichtung in eine im Wesentlichen vertikale Ausrichtung umlenkt. FIG. 3 shows a frontal view of the magazine 10 for the provision of edge protection means 13. Shown is the reservoir 22, within which edge protection means 13 are arranged in a stack. The magazine is placed on supports 23 and has a to the viewer FIG. 3 facing baffle 18, which in conjunction with a in FIG. 1 described in more detail the plate-like edge protection means 13 deflects from a substantially horizontal orientation in a substantially vertical orientation.

Das Kantenschutzmittel 13 wird von dem später noch im Einzelnen zu beschreibenden Vortrieb in Förderrichtung x aus dem Magazin 10 in Richtung einer nicht dargestellten Anordnungseinrichtung bewegt. Ein Walzenpaar 24 bildet das in Förderrichtung x vorn liegende, anordnungseinrichtungsnahe Ende des erfindungsgemäßen Vortriebs.The edge protection means 13 is moved by the drive to be described in detail later in the conveying direction x from the magazine 10 in the direction of an arrangement device, not shown. A pair of rollers 24 forms the upstream in the conveying direction x, arrangement near the arrangement end of the propulsion system according to the invention.

Figur 1 stellt eine Schnittansicht gemäß Schnittlinie I-I in Figur 3 dar. Die Blickrichtung dieser Ansicht entspricht der Förderrichtung x. FIG. 1 represents a sectional view along section line II in FIG. 3 The viewing direction of this view corresponds to the conveying direction x.

Dargestellt ist zunächst das insgesamt mit der Bezugsziffer 10 bezeichnete Magazin in einer Teilansicht.Shown is initially the magazine designated overall by the reference numeral 10 in a partial view.

Das Magazin 10 umfasst zunächst ein über Zahnräder 11 endlos umlaufend geführtes Vortriebsmittel 12. Das Vortriebsmittel verbringt das jeweils zur Entnahme vorgesehene Kantenschutzmittel 13 aus dem Vorratsbehälter 22 bis zum Krümmungsabschnitt 15 einer Förderfläche 14. Das Kantenschutzmittel 13 gleitet durch sein Eigengewicht am Krümmungsabschnitt 15 entlang, bis es zu einem Vertikalabschnitt 16 der Förderfläche 14 gelangt. Teil des Magazins 10 ist darüber hinaus ein Leitblech 18, welches im Zusammenwirken mit dem Vertikalabschnitt 16 die Seitenwände eines Kanalabschnittes 17 bildet. Bodenseitig liegt in dem Kanalabschnitt 17 ein endlos umlaufend geführtes Fördermittel 19 ein, welches eine erste Umlenkung durch die dargestellte Umlenkrolle 20 erfährt. Das Kantenschutzmittel 13 liegt mit seiner Schmalseite 21 auf dem Fördermittel 19 auf. Allein die Kraft des Eigengewichtes des Kantenschutzmittels 13 führt zu einem Reibschluss mit dem Fördermittel 19, welcher für eine zuverlässige Bewegung in Förderrichtung x ausreichend ist.The magazine 10 initially comprises a drive means 12 guided endlessly circumferentially by means of toothed wheels 11. The advance means spends the respective edge protection means 13 provided for removal from the storage container 22 up to the curved portion 15 of a conveying surface 14 Edge protection means 13 slides by its own weight along the curvature section 15 until it reaches a vertical section 16 of the conveying surface 14. Part of the magazine 10 is also a guide plate 18, which forms the side walls of a channel portion 17 in cooperation with the vertical portion 16. On the bottom side lies in the channel section 17, an endlessly circulating guided conveyor 19, which undergoes a first deflection by the illustrated guide roller 20. The edge protection means 13 lies with its narrow side 21 on the conveyor 19.

Das Walzenpaar 24 wird von einer ersten Walze 25 und einer zweiten Walze 26 gebildet, wobei das Fördermittel 19 seine zweite Umlenkung im vorliegenden Ausführungsbeispiel durch die erste Walze 25 erfährt. Über die erste Umlenkung durch Führung entlang der Umlenkrolle 20 und die zweite Umlenkung durch Führung entlang der ersten Walze 25 ist der Endlosumlauf des Fördermittels 19 gewährleistet. Selbstverständlich kann die zweite Umlenkung auch durch eine separate weitere Umlenkrolle erfolgen und muss nicht zwingend mit der ersten Walze 25 gekoppelt sein.The pair of rollers 24 is formed by a first roller 25 and a second roller 26, wherein the conveyor 19 undergoes its second deflection in the present embodiment by the first roller 25. About the first deflection by guiding along the guide roller 20 and the second deflection by guiding along the first roller 25 of the endless circulation of the conveyor 19 is ensured. Of course, the second deflection can also be effected by a separate further deflection roller and does not necessarily have to be coupled to the first roller 25.

Der wesentliche Vorteil bei der erfindungsgemäß aufgeführten Umlenkung des Fördermittels 19 ist, dass die erste Walze 25 durch den Umlauf des Fördermittels 19 in Rotation versetzt wird und so im Zusammenspiel mit der zweiten Walze 26 das Kantenschutzmittel 13 nicht nur in seiner Ausrichtung zur Übergabe an die Anordnungseinrichtung stabilisiert, sondern die Ausförderung unterstützt. Diese unterstützende Wirkung kommt insbesondere dann zum Tragen, wenn die Förderung des Kantenschutzmittels 13 in Förderrichtung x fortgesetzt wird und mit stetiger Ausförderung aus dem Vortrieb die gemeinsame Kontaktfläche von Kantenschutzmitteln 13 und Fördermittel 19 geringer wird.The main advantage of the inventive deflection of the conveyor 19 is that the first roller 25 is rotated by the circulation of the conveyor 19 in rotation and so in interaction with the second roller 26 not only stabilizes the edge protection means 13 in its orientation for transfer to the arranging means, but also promotes the conveyance. This supporting effect comes into play, in particular, when the conveyance of the edge protection agent 13 in the conveying direction x is continued and the common contact surface of the edge protection means 13 and the conveying means 19 becomes smaller with continuous removal from the drive.

Des Weiteren ist bei der ausführungsgemäßen Umlenkung des Fördermittels 19 durch die erste Walze 25 nur ein Antrieb notwendig, um sowohl die erste Walze 25 wie auch das Fördermittel 19 in Bewegung zu versetzen.Furthermore, in the embodiment of the deflection of the conveyor 19 by the first roller 25 only one drive is necessary to enable both the first roller 25 as well as the conveyor 19 in motion.

Dem Walzenpaar 24 sind zwei zueinander beabstandete Fangbleche 27 in Förderrichtung x vorgeordnet, die insbesondere in Einschubrichtung x hinten trichterförmig aufgeweitet sind, um das Kantenschutzmittel 13 dem Walzenpaar 24 zu zuführen. Die erste und zweite Walze 25 und 26 des Walzenpaares 24 sind federbelastet, um einen ausreichenden Andruck am Kantenschutzmittel 13 und hierdurch eine ordnungsgemäße Ausförderung desselben sicherzustellen.The roller pair 24 are two spaced catch plates 27 upstream in the conveying direction x, which are widened funnel-shaped in particular in the insertion direction x back to the edge protection means 13 to perform the roller pair 24. The first and second rollers 25 and 26 of the roller pair 24 are spring loaded to ensure sufficient pressure on the edge protection means 13 and thereby proper discharge thereof.

Figur 4 zeigt eine der Figur 3 ähnliche Ansicht des Magazins 10. Der wesentliche Unterschied zu Figur 3 besteht jedoch darin, dass das Kantenschutzmittel 13 quasi ausgefördert und an eine nicht dargestellte Anordnungseinrichtung übergeben ist. Es hat somit den Wirkbereich des erfindungsgemäßen Vortriebs verlassen. FIG. 4 shows one of the FIG. 3 similar view of the magazine 10. The main difference to FIG. 3 However, it consists in that the edge protection means 13 is quasi conveyed and handed over to an arrangement device, not shown. It has thus left the effective range of the propulsion according to the invention.

Festzuhalten ist demnach, dass der erfindungsgemäße Vortrieb zumindest ein endlos umlaufendes Fördermittel 19 umfasst, welches das vereinzelte Kantenschutzmittel 13 allein durch dessen Eigengewicht zu einer nicht dargestellten Anordnungseinrichtung einer Umreifungsvorrichtung bewegt. In dem hier dargestellten Ausführungsbeispiel umfasst der Vortrieb zusätzlich den vorbeschriebenen Kanalabschnitt 17 sowie das Walzenpaar 24, die beide die Ausrichtung des Kantenschutzmittels 13 für die spätere Anordnung an einem Packstück stabilisieren. Dabei dient das Walzenpaar 24 einer ausrichtungsgerechten Ausförderung und Übergabe an die angesprochen Anordnungseinrichtung. Ein wesentlicher Vorteil ist hier, dass die erste Walze 25 auch als Umlenkeinrichtung für das Fördermittel 19 dient oder aber mit einer Umlenkeinrichtung bewegungsgekoppelt ist. So reicht ein Antrieb aus, um die erste Walze 25 und das Fördermittel 19 in Bewegung zu versetzen.It should be noted, therefore, that the propulsion according to the invention comprises at least one endlessly circulating conveying means 19, which moves the separated edge protection means 13 solely by its own weight to an arrangement device (not shown) of a strapping device. In the embodiment shown here, the propulsion comprises In addition, the above-described channel portion 17 and the pair of rollers 24, both of which stabilize the orientation of the edge protection means 13 for later arrangement on a package. In this case, the pair of rollers 24 is an alignment-oriented discharge and transfer to the addressed arrangement device. A significant advantage here is that the first roller 25 also serves as a deflection device for the conveyor 19 or is coupled in motion with a deflection device. So a drive is sufficient to enable the first roller 25 and the conveyor 19 in motion.

Erfindungsgemäß ist vorgesehen, dass der Vortrieb Teil einer ausfahrbaren Schiene 28 ist, die ebenfalls in Förderrichtung x aus dem Magazin ausfahrbar ist. Diese Schiene trägt die Umlenkrolle 20 sowie das Walzenpaar 24 nebst Fördermittel 19, ist jedoch zum Kanalabschnitt 17 relativ beweglich. Zur Übergabe des Kantenschutzmittels 13 an eine Anordnungseinrichtung kann zunächst die Schiene 28 in Förderrichtung x bewegt werden, woran sich die eigentliche Ausförderung des Kantenschutzmittels 13 über das Fördermittel 19 und das Walzenpaar 24 anschließt. Auf diese Weise können größere Distanzen zur Anordnungseinrichtung überbrückt werden. Im Anschluss an die Ausförderung fährt die Schiene 28 zurück, um das nächste Kantenschutzmittel 13 aufzunehmen.According to the invention it is provided that the propulsion part of an extendable rail 28, which is also extendable in the conveying direction x from the magazine. This rail carries the guide roller 20 and the pair of rollers 24 together with conveying means 19, but is relatively movable to the channel section 17. To transfer the edge protection means 13 to an arrangement device, the rail 28 can first be moved in the conveying direction x, followed by the actual removal of the edge protection means 13 via the conveying means 19 and the roller pair 24. In this way, greater distances to the arrangement device can be bridged. Following the removal, the rail 28 retracts to receive the next edge protection means 13.
