Description

Die Erfindung bezieht sich auf eine Vorrichtung zum winkligen Umlenken eines in Formation herangeführten Stroms von Flächengebilden, insbesondere in Schuppenform herangeführter Papierprodukte, mit einer Einlaufvorrichtung, einer Auslaufvorrichtung und zwei die Flächengebilde eingespannt führenden Preßbändern o.dgl..The invention relates to a device for angularly deflecting a flow of sheet-like structures, particularly paper products, in an imbricated form, with an inlet device, an outlet device and two press belts or the like, which clamp the sheet-like structures.

Aus der DE-OS 25 29 103 ist eine Fördervorrichtung für blattförmiges Material, vorzugsweise Röntgenfilmblätter, bekannt, bei der über eine im Winkel von 45° zur Richtung der zugeführten Bänder freiumlaufenden Walze die beiden Preßbänder umgelenkt werden; die Röntgenfilmblätter werden hierbei in einer willkürlichen Stellung zwischen den Preßbändern gehalten und gefördert. Bei dieser bekannten Vorrichtung ist es nicht möglich, die Formation eines Schuppenstromes einzelner Papierprodukte auch während der Umlenkung beizubehalten.From DE-OS 25 29 103 a conveying device for sheet material, preferably X-ray film sheets, is known, in which the two press belts are deflected by a roller running freely at an angle of 45 ° to the direction of the fed belts; The X-ray film sheets are held and conveyed in an arbitrary position between the press belts. In this known device, it is not possible to individually form a shingled stream Maintain paper products even during the redirection.

Aus der CH-PS 435 323 ist eine Fördereinrichtung zum Fördern von Belegen bekannt; bei dieser Vorrichtung wird der Schuppenstrom in der Schuppenstromebene durch Führungsrollen bzw. Führungsbänder "gebogen".From CH-PS 435 323 a conveyor for conveying documents is known; in this device the scale flow is "bent" in the scale flow level by guide rollers or guide belts.

Der Erfindung liegt die Aufgabe zugrunde, den in Formation herangeführten Strom von Flächengebilden, insbesondere in Schuppenstrom herangeführter Papierprodukte, in der Ebene des Schuppenstroms winklig umzulenken.The invention is based on the object of deflecting the flow of sheetlike structures brought up in formation, in particular paper products brought up in shingled stream, at an angle in the plane of the shingled stream.

Die Aufgabe wird dadurch gelöst, daß erfindungsgemäß die Preßbänder einen runden oder annähernd runden Querschnitt aufweisen und an der Stelle der winkligen Umlenkung der Flächengebilde um 0 -45° durch Führungsrollenpaare mit Teilringnuten umlenkbar sind, deren Achsen senkrecht zum Strom der Flächengebilde verlaufen.The object is achieved in that, according to the invention, the press belts have a round or approximately round cross section and can be deflected at the location of the angular deflection of the fabrics by 0 -45 ° by pairs of guide rollers with partial ring grooves, the axes of which are perpendicular to the flow of the fabrics.

Erst dann, wenn die Flächengebilde an der Stelle der Umlenkung erfaßt und eingespannt gehalten werden, ist ein Schuppenstrom umlenkbar, ohne daß die einzelnen Schuppen sich in bezug aufeinander verschieben können. Dies ist jedoch notwendig, wenn eine Umlenkvorrichtung zur Förderung von einem Schuppenstrom von Papierprodukten mit der Geschwindigkeit z.B. bis zu 40 000 Stück/Std. eingesetzt wird. Der störungsfreie Betrieb der nachfolgenden Vorrichtungen, z.B. einer Rotationsschneidanlage, bedingt eine genaue und exakte Umlenkung des Schuppenstromes ohne gegenseitige Verschiebungen der einzelnen Schuppen.Only when the flat structures are grasped and held in place at the point of deflection can a shingled stream be deflected without the individual sheds being able to shift with respect to one another. However, this is necessary if a deflection device for conveying a shingled stream of paper products at the speed e.g. up to 40,000 pieces / hour is used. Trouble-free operation of the following devices, e.g. a rotary cutting system, requires an exact and exact deflection of the shingled stream without mutual shifts of the individual sheds.

Es ist zwar aus der CH-PS 530 925 eine Fördereinrichtung zum Fördern von Belegen bekannt, bei der zum Halten der Belege und zu ihrem Antrieb zwischen seitlichen Führungsplatten bewegbare, endlose Riemen verwendet werden, die sich in Längsrichtung des Transportkanals erstrecken, jeweils einen etwa kreisförmigen Querschnitt aufweisen und gegeneinander versetzt sind, um gegen verschiedene Stellen eines Belegs in Eingriff zu kommen. Mit dieser Vorrichtung ist eine Umlenkung des Produktstroms in der Produktstromebene nicht möglich.It is known from CH-PS 530 925 a conveyor for conveying documents, in which to hold the documents and endless belts movable for driving between lateral guide plates are used, which extend in the longitudinal direction of the transport channel, each have an approximately circular cross section and are offset from one another in order to engage against different points of a document. A deflection of the product flow in the product flow level is not possible with this device.

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 on a rail 11 which extends 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.

Wie aus Fig. 2 ersichtlich ist, erfolgt die Arretierung der unteren Elemente 10 über in die Stange 11 einschraubbarer Stifte 20.As can be seen from FIG. 2, the lower elements 10 are locked via pins 20 that can be screwed into the rod 11.

Jedes Element 10 bzw. 13 weist einen blockartigen Halter 21 und einen Träger 22 auf. Der blockartige Halter umschließt gabelförmig eine Führungsrolle 23, deren Achse 24 senkrecht zum Produktstrom verläuft. Die Führungsrolle 23 ist mit zwei halbkreisförmigen Ringnuten zur Aufnahme eines Preßbandes 25 mit rundem Querschnitt versehen. Das Preßband 25 ist ein Endlosband, welches am Auslauf durch eine Führungsrolle 26 gehalten ist, deren Achse 27 zwar senkrecht zum Produktstrom verläuft, jedoch in der horizontalen Ebene zwischen 0° und 45° verschwenkbar ist. Bei der in Fig.3 dargestellten Draufsicht auf das Element 13 ist der Träger 22 mit der Führungsrolle 26 in einem Winkel von 45° zur Einlaufrichtung des Produktstromes verstellt.Each element 10 or 13 has a block-like holder 21 and a carrier 22. The block-like holder surrounds a guide roller 23 in the form of a fork, the axis 24 of which runs perpendicular to the product flow. The guide roller 23 is provided with two semicircular ring grooves for receiving a press belt 25 with a round cross section. The press belt 25 is an endless belt, which is held at the outlet by a guide roller 26, the axis 27 of which runs perpendicular to the product flow, but can be pivoted in the horizontal plane between 0 ° and 45 °. 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 entry 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 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 deflecting rollers 29 and 30 provided on the underside of the carrier 22 are designed such that the respective annular groove is offset to the outside with respect to the central plane of the respective deflecting rollers. 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. 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.
