Description

Die Erfindung bezieht sich auf eine Umlenkvorrichtung für einen in Formation herangeführten Strom von Produk­ten, insbesondere in Schuppenform herangeführten Papier­produkten mit einem Einlauf, einer Auflaufplatte und einem Auslauf.The invention relates to a deflection device for a flow of products, in particular in the form of scales, of paper products with an inlet, a ramp plate and an outlet.

Bei der Bearbeitung von Papierprodukten, insbesondere solchen, die mehrlagig in Schuppenform gefördert werden, ist häufig eine in der horizontalen Ebene erfolgende Umlenkung des Produktstromes um einen bestimmten Winkel, gewöhnlich um 90°, erforderlich. Dies gilt vor allem, wenn die Papierprodukte an drei Seiten beschnitten oder besäumt werden sollen. Für eine derartige Umlenkung werden Umlenkstationen verwendet, die gewöhnlich eine horizontale Platte, eine senkrecht dazu verlaufende, auf der horizontalen Platten verstellbare Auflaufplatte aufweisen und gegebenenfalls mit einer Umlenkwalze ver­sehen sind. Die Umlenkung der Produkte um 90° wird so­mit auf dem Tisch oder der Auflageplatte vorgenommen. Um die Umlenkung zu erleichtern und vor allen Dingen Veränderungen in der Formation der Produkte zu verhin­ hindern, ist es bekannt, unmittelbar nach dem Einlauf eine Umlenkung des Produktstromes zunächst um 45° vor­zunehmen und erst dann die weitere Umlenkung um weitere 45°. Bei dieser bekannten Vorrichtung ist es jedoch nicht möglich, eine Verstellung des Winkels vorzunehmen.When processing paper products, in particular those which are conveyed in multiple layers in the form of scales, it is often necessary to deflect the product stream in the horizontal plane by a certain angle, usually by 90 °. This is especially true if the paper products are to be trimmed or trimmed on three sides. For such a deflection, deflection stations are used, which usually have a horizontal plate, a run-up plate running perpendicular to it and adjustable on the horizontal plates, and are optionally provided with a deflection roller. The products are thus deflected by 90 ° on the table or the platen. To facilitate the redirection and, above all, to prevent changes in the formation of the products prevent it, it is known to immediately deflect the product stream first by 45 ° and only then further deflect it by a further 45 °. In this known device, however, it is not possible to adjust the angle.

Der Erfindung liegt die Aufgabe zugrunde, den Produkt­strom beim Einlauf in verschiedenen Winkellagen - je nach den Erfordernissen - unzulenken.The invention is based, to steer the product flow at the inlet in different angular positions - depending on the requirements.

Die Aufgabe wird dadurch gelöst, daß erfindungsgemäß im Einlauf für eine winklige Umlenkung des Produktstromes zwischen 0 - 45° eine entsprechende Führung der den Produktstrom erfassenden Preßbänder o.dgl. vorgesehen ist. Unter Preßbändern im Sinne der Erfindung sind auch Gurte, entsprechend starke Gummibänder oder auch profilierte Gummibänder zu verstehen; es sind darunter auch Gliederketten, gegebenenfalls mit einer zum Produkt­strom gerichteten Gummiauflage zu verstehen.The object is achieved in that, according to the invention, in the inlet for an angular deflection of the product flow between 0 - 45 °, a corresponding guidance of the press belts or the like which detects the product flow. is provided. Press belts in the sense of the invention also include belts, appropriately strong rubber bands or profiled rubber bands; it also includes link chains, possibly with a rubber pad facing the product stream.

Der einlauf kann mindestens zwei zusammenwirkende Preß­bandpaare o.dgl. aufweisen, deren Förderrichtung zwischen 0 - 45° verstellbar ist.The inlet can or the like at least two interacting pairs of press belts. have, whose conveying direction is adjustable between 0 - 45 °.

Nach einer bevorzugten Ausführungsform der Erfindung weist jedes Preßbandpaar o.dgl. eine Führungsrolle, eine Führungswalze o.dgl. auf, deren Achse senkrecht zur Ein­laufrichtung - vorzugsweise in waagerechter Ebene - verläuft und welches mindestens eine Führungsrolle mit einer dazu, vorzugsweise in der waagerechten Ebene, verschwenkbaren Achse hat. Die verschwenkbare Achse kann an einem Träger o.dgl. vorgesehen sein, welcher mindestens eine Umlenkrolle o.dgl. mit einer Achse senkrecht zu den Achsen der Führungsrollren aufweist, wobei das Preßband o.dgl. einen runden oder annähernd runden Querschnitt hab en kann. Die Umlenkrollen o.dgl. sind zweckmäßigerweise paarweise angeordnet.According to a preferred embodiment of the invention, each pair of press belts or the like. a guide roller, a guide roller or the like. on, the axis of which runs perpendicular to the direction of entry - preferably in a horizontal plane - and which has at least one guide roller with an axis which can be pivoted thereon, preferably in the horizontal plane. The pivotable axis or the like on a support. be provided which has at least one deflection roller or the like. has an axis perpendicular to the axes of the guide roller wheels, the press belt or the like. can have a round or approximately round cross-section. The pulleys or the like. are expediently arranged in pairs.

Vorzugsweise schließen der Halter und der Träger des einen endlosen Preßbandes o.dgl. in bezug auf den Halter und den Träger des zugeordneten Preßbandes o.dgl. einen zum Zuförderer sich öffnenden spitzen Winkel ein. Be­vorzugterweise ist bzw. sind mindestens ein Preßband­paar(e) o.dgl. in bezug auf das oder die benachbarte(n) Preßbandpaar(e) in der Höhe verstellbar. Durch die Höhenverstellung eines nicht am Rande des Produkt­stromes liegenden Preßbandpaares o.dgl. kann erreicht werden, daß die Formation einen kleinen Bug im mittleren Bereich erhält, wodurch das Papierprodukt bzw. die ganze Formation beim Einlauf in die Umlenkvorrichtung ausge­steift wird. Selbstverständlich ist es unwesentlich, ob dieser kleine Bug nach unten oder nach oben gerich­tet ist.Preferably, the holder and the carrier of the one endless press belt or the like close. or the like with respect to the holder and the carrier of the associated press belt. an acute angle opening towards the feed conveyor. Preferably, at least one pair of press belts or the like is or are. adjustable in height with respect to the adjacent pair of press belts. By adjusting the height of a pair of press belts or the like not lying on the edge of the product stream. can be achieved that the formation receives a small bow in the middle, whereby the paper product or the entire formation is stiffened when entering the deflection device. Of course, it doesn't matter whether this little bug is pointing downwards or upwards.

Die Halter der unteren Preßbänder o.dgl. und diejenigen der oberen Preßbänder o.dgl. sind zweckmäßigerweise je auf einer Welle gelagert und tragen jeweils eine, ge­gebenenfalls angetriebene Führungsrolle, Führungswalze o.dgl.; beide Wellen können durch an deren einem Ende angebrachte Zahnräder o.dgl. synchron laufen, wobei nur eine Welle am anderen Ende angetrieben sein kann.The holder of the lower press belts or the like. and those of the upper press belts or the like. are expediently each mounted on a shaft and each carry an optionally driven guide roller, guide roller or the like; both shafts or the like can be attached by gears attached to one end. run synchronously, whereby only one shaft can be driven at the other end.

Nach einer bevorzugten Ausführungsform der Erfindung können die Träger o.dgl. in Auslaufrichtung in der horizontalen Ebene spitz zulaufen und jeweils eine Führungsrolle o.dgl. tragen. Durch die Öffnung des Preßbandpaares in Richtung auf den Zuförderer wird die Konstruktion insofern vereinfacht, als die Erfassung des Produktstromes erst im Abstand von den vorder­seitigen Führungsrollen erfolgt, und zwar nach der vorgesehenen Umlenkung der Preßbänder in die vorge­sehene Winkellage.According to a preferred embodiment of the invention, the carrier or the like. taper to a point in the horizontal plane and a guide roller or the like. wear. By opening the pair of press belts in the direction of the feed conveyor, the construction is simplified insofar as the detection of the product flow takes place only at a distance from the front guide rollers, specifically after the intended deflection of the press belts into the intended angular position.

Die Träger o.dgl. können am Rand der Einlaufseite min­destens im Abstand von ihrer unteren und der oberen senkrecht zur Achse der Führungsrolle, Führungswalze o.dgl. verlaufenden Oberfläche mindestens je eine Um­lenkrolle, Umlenkwalze o.dgl. tragen. Besonders bevor­zugt ist eine Ausführungsform, bei der der Halter und/oder Träger o.dgl., vorzugsweise der obere Halter eines jeden Preßbandpaares um seine Welle verschwenkbar und federnd gelagert ist. Auf diese Weise wird einerseits eine federnde Auflage des oberen Halters und Trägers er­reicht und es andererseits eine Anpassung an unter­schiedliche Stärken des Produktstromes möglich.The carrier or the like. can at the edge of the inlet side at least at a distance from its lower and the upper perpendicular to the axis of the guide roller, guide roller or the like. running surface at least one deflection roller, deflection roller or the like. wear. An embodiment is particularly preferred in which the holder and / or carrier or the like, preferably the upper holder of each pair of press belts, is pivotably and resiliently mounted about its shaft. In this way, on the one hand a resilient support of the upper holder and carrier is achieved and on the other hand an adaptation to different strengths of the product flow is possible.

Die Halter der jeweiligen Preßbänder o.dgl. sind vorzugs­weise auf ihren Wellen verschiebbar und an einer wellen­parallelen Stange o.dgl. arretierbar. Die ober- und unterhalb der Träger vorgesehenen Umlenkrollen, Umlenk­walzen o.dgl. weisen vorzugsweise jeweils eine gemein­same annähernd lotrecht verlaufende Welle o.dgl. auf. Es ist auch möglich, daß die beiden Wellen o.dgl. in einem vertikalen, gegebenenfalls eckigen Rahmen o.dgl. gehalten sind, welcher an der Einlaufseite der Umlenk­vorrichtung lösbar anbringbar ist.The holder of the respective press belts or the like. are preferably slidable on their shafts and the like on a shaft parallel to the shaft. lockable. The deflection rollers, deflection rollers or the like provided above and below the carrier. each preferably have a common approximately perpendicular shaft or the like. on. It is also possible that the two waves or the like. in a vertical, possibly square frame or the like. are held, which is releasably attachable to the inlet side of the deflection device.

Während die winklige Verstellung ohne weiteres stufen­los zwischen den Winkeln 0° und 45° erfolgen kann, sind für eine stufenweise Verstellung der Träger o.dgl. Keile o.dgl. verschiedener Größe vorgesehen. Auch kann eine Achse der Umlenkrolle o.dgl. eines Trägers o.dgl. als Verschwenkachse des letzteren ausgebildet sein.While the angular adjustment can be made continuously between the angles 0 ° and 45 °, the carrier or the like are for a gradual adjustment. Wedges or the like of various sizes. An axis of the deflection roller or the like can also. a carrier or the like be designed as a pivot axis of the latter.

Ein rechteckiger Rahmen 1, der sich senkrecht zur Zeichenebene erstreckt und dessen eine Querseite ge­zeigt ist, trägt zwei Wellen 2 und 3, welche mittels eines Endlosbandes 4 von einem Elektromotor 5 aus synchron angetrieben werden. Die beiden Wellen 2 und 3 werden über an einem ihrer Enden vorgesehene Zahnräder 6 und 7 synchron angetrieben. Auf jeder Welle 2 und 3 sind Elementenpaare 8 gelagert. Es müssen mindestens zwei solcher Elementenpaare vorgesehen werden; bei üblichen Rotationsschneidanlagen mit einer den Rahmen 1 aufweisenden Eckumlenkung am Einlauf werden mindestens drei, möglicherweise vier bis fünf Elementenpaare 8 vorgesehen werden. Die Produktstromrichtung vom Zu­förderer ist mit dem Pfeil 9 angedeutet.A rectangular frame 1, which extends perpendicular to the plane of the drawing and whose one transverse side is shown, carries two shafts 2 and 3, which are driven synchronously by means of an endless belt 4 from an electric motor 5. The two shafts 2 and 3 are driven synchronously via gear wheels 6 and 7 provided at one of their ends. Pairs of elements 8 are mounted on each shaft 2 and 3. At least two such pairs of elements must be provided; In conventional rotary cutting systems with a corner deflection having the frame 1 at the inlet, at least three, possibly four to five pairs of elements 8 will be provided. The direction of product flow from the feed conveyor is indicated by arrow 9.

Jedes Elementenpaar besteht aus zwei im wesentlichen gleich ausgebildeten Elementen, wobei das untere Element 10 an eine senkrecht zur Zeichenebene verlaufenden, sich über die Breite des Rahmens erstreckenden Schiene 11 arretiert ist. Die Längsachse 12 des unteren Elements 10 verläuft horizontal. Die Befestigung der einzelnen unteren Elemente an der Schiene 11 erfolgt in gleich­mäßigen Abständen.Each pair of elements consists of two essentially identical elements, the lower element 10 being locked to a rail 11 which runs perpendicular to the plane of the drawing and extends across the width of the frame. The longitudinal axis 12 of the lower element 10 runs horizontally. The fastening of the individual lower elements on the rail 11 takes place at regular intervals.

Das obere Element 13 ist mit seiner Längsachse 14 in einem spitzen Winkel zur Längsachse 12 des unteren Elements angeordnet; es ist - wie nachfolgend näher be­schrieben - federnd gelagert und in der Höhe verstell­bar. Die einzelnen Elemente 13 sind darüber hinaus auch um den Drehpunkt 15 in Pfeilrichtung 16 verschwenkbar.The upper element 13 is with its longitudinal axis 14 at an acute angle to the longitudinal axis 12 of the lower Elements arranged; it is - as described in more detail below - spring-loaded and adjustable in height. The individual elements 13 can also be pivoted about the pivot point 15 in the direction of the arrow 16.

In the plan view of the element 13 shown in FIG. 3, the carrier 22 with the guide roller 26 is adjusted at an angle of 45 ° to the direction of flow of the product stream.

Das oberhalb und unterhalb des Halters 21 und des Trägers 22 umlaufende Endlosband 25 ist durch zwei Umlenkrollen 27 und 28 auf der Oberseite des Trägers 22 und durch ein entsprechendes Umlenkrollenpaar an der Unterseite des Trägers 22 geführt. Bei der winkligen Verstellung des Trägers 22 um die Achse 30, die gleich­zeitig die Drehachse der Umlenkrolle 28 und der ent­sprechenden Umlenkrolle auf der Unterseite des Trägers ist, verläuft das Endlosband 25 an der Oberseite des Halters 21 und des Trägers 22 wie dargestellt und an der Unterseite dementsprechend.The endless belt 25 running above and below the holder 21 and the carrier 22 is guided through two deflection rollers 27 and 28 on the top of the carrier 22 and through a corresponding pair of deflection rollers on the underside of the carrier 22. In the angular adjustment of the carrier 22 about the axis 30, which is also the axis of rotation of the deflection roller 28 and the corresponding deflection roller on the underside of the carrier, the endless belt 25 runs on the top of the holder 21 and the carrier 22 as shown and on the Bottom accordingly.

Die Umlenkrollen 27 bzw. 28 und die entsprechenden, an der Unterseite des Trägers 22 vorgesehenen Umlenk­rollen 29 und 30 sind so ausgebildet, daß die jeweilige Ringnut 23′ in bezug auf die Mittelebene der jeweiligen Umlenkrollen jeweils nach außen versetzt ist. Auf diese Weise wird erreicht, daß die Außenseite des Endlos­bandes 25 den freien Rand der jeweiligen Umlenkrolle 27 - 30 überragt.The deflecting rollers 27 and 28 and the corresponding, provided on the underside of the support 22 deflecting rollers 29 and 30 are formed so that the respective annular groove 23 'is offset in relation to the center plane of the respective deflecting rollers to the outside. In this way it is achieved that the outside of the endless belt 25 projects beyond the free edge of the respective deflection roller 27-30.

Wie insbesondere aus Fig. 2 ersichtlich ist, umgreifen die beiden Arme 40, 41 des Trägers 22 einen entsprechen­den Vorsprung 42 des Halters 22. Während die nicht ge­zeigte Welle der Achse 30 in diesem Vorsprung 42 ge­lagert ist, hat der entsprechende Vorsprung (s. Fig.3) eine Aussparung 43, in welche die durchgehende Welle der Achse 44 bei eingeschwenktem Träger 22 unterge­bracht wird.As can be seen in particular from FIG. 2, the two arms 40, 41 of the carrier 22 engage around a corresponding projection 42 of the holder 22. While the shaft 30, not shown, is mounted in this projection 42, the corresponding projection (see FIG .3) a recess 43 into which the continuous shaft of the axis 44 is accommodated when the carrier 22 is pivoted in.

Während das untere Element 10 ortsfest ist, kann das obere Element 13 um die Achse 50 nach oben verschwenkt werden, wobei ein Stift 51 an der Oberseite des Trägers 22 in einen parallel zur Zeichenebene verlau­fenden Längsschlitz 52 eingreift. Durch den Längs­schlitz ist gewährleistet, daß der Träger 22 des Elements 13 nicht seitlich ausweichen kann. Auf der anderen Seite ist der den Längsschlitz 52 aufweisende Flansch 53 um die Achse 54 verschwenkbar, so daß die in Fig. 3 von oben dargestellte Stellung des Trägers 22 des Elements 13 erreicht werden kann. Der Längs­schlitz 52 ermöglicht darüber hinaus jedoch ein Hoch­schwenken des Elements 13 um die Achse 5, wobei der in den Längsschlitz hineinragende Stift 51 zwischen den beiden dargestellten Stellungen hin- und herbewegt werden kann.While the lower element 10 is stationary, the upper element 13 can be pivoted upward about the axis 50, a pin 51 on the upper side of the carrier 22 engaging in a longitudinal slot 52 running parallel to the plane of the drawing. The longitudinal slot ensures that the carrier 22 of the element 13 cannot escape laterally. On the other hand, the flange 53 having the longitudinal slot 52 can be pivoted about the axis 54, so that the position of the carrier 22 of the element 13 shown from above in FIG. 3 can be achieved. However, the longitudinal slot 52 also allows the element 13 to be pivoted up about the axis 5, the pin 51 projecting into the longitudinal slot being able to be moved back and forth between the two positions shown.

Der Halter 21 des oberen Elements 13 ist darüber hinaus über einen Flansch 60 mit einer Feder 61 verbunden, so daß das Element 13 auch um die Achse 50 in gewissem Ausmaß federn kann. Die Arretierung des Trägers 22 in eine beliebige Winkelstellung zwische 0° und 45° kann auf beliebige Weise erfolgen; es ist jedoch auch möglich, eine stufenweise Arretierung dieses Trägers in der Winkelstellung zwischen 0° und 45° durch Keile zu bewirken. Die Umlenkung des Produktstromes von der Pfeilrichtung 9, beispielsweise in die Pfeilrichtung 62, erfolgt so, daß der Produktstrom vom Zuförderer in den offenen Spalt zwischen den beiden Führungsrollen 23 mit ihren Endlosbändern 25 hineingeschoben wird und daß durch den sich verengenden Spalt der Produkt­strom, wie in Fig. 2 dargestellt, erst im Bereich der Führungsrollen 26 erfaßt und entsprechend umgelenkt wird.The holder 21 of the upper element 13 is also connected via a flange 60 to a spring 61, so that the element 13 can also spring to a certain extent about the axis 50. The support 22 can be locked in any angular position between 0 ° and 45 ° in any way; however, it is also possible to effect a gradual locking of this carrier in the angular position between 0 ° and 45 ° by means of wedges. The deflection of the product stream from the arrow direction 9, for example in the arrow direction 62, is carried out in such a way that the product stream is pushed by the feed conveyor into the open gap between the two guide rollers 23 with its endless belts 25 and that the product stream is narrowed by the narrowing gap, as in FIG Fig. 2 shown, only detected in the region of the guide rollers 26 and deflected accordingly.

Statt der dargestellten und beschriebenen Preßbänder mit rundem Querschnitt können auch Gurte oder Riemen z.B. in Hochkantlage Verwendung finden; es ist auch möglich, statt der Endlosbänder 25 Gliederketten zu verwenden; diese wären dann an der Außenseite mit entsprechenden Gummiprofilen oder elastischen Kunststoffprofilen zu versehen.Instead of the illustrated and described press belts with a round cross-section, belts or belts e.g. used in an upright position; it is also possible to use 25 link chains instead of the endless belts; these would then have to be provided on the outside with appropriate rubber profiles or elastic plastic profiles.
