Abstract

Entre une première et une deuxième section de transport (1, 23) se trouve un décrochement (20) conduisant vers le bas au niveau duquel un premier flux de nappes (20) est réparti et transféré pour constituer un deuxième flux de nappes dévié (3). Avant et après le décrochement (20) sont disposés des cylindres de pression (5, 10) qui sont placés contre la face supérieure du premier ou du deuxième flux de nappes (2, 3) et qui forment des dispositifs permettant de diriger le deuxième flux de nappes (3). On peut ainsi obtenir, sans paroi de guidage latéral, une homogénéité et une direction constante du flux de nappes dévié (3).Between a first and a second conveying section (1, 23) there is a step (20) leading downwards at which a first flow of webs (20) is distributed and transferred to constitute a second diverted flow of webs (3 ). Before and after the recess (20) are arranged pressure cylinders (5, 10) which are placed against the upper face of the first or the second flow of webs (2, 3) and which form devices for directing the second flow of tablecloths (3). It is thus possible to obtain, without a lateral guide wall, a homogeneity and a constant direction of the flow of deviated layers (3).

Description

Einrichtung zum Ueberführen eines aus Druckprodukten gebil¬ deten SchuppenstromsDevice for transferring a stream of scale formed from printed products
Die Erfindung betrifft eine Einrichtung zum Ueberführen ei¬ nes auf einer ersten Förderstrecke geförderten, aus Druck¬ produkten gebildeten ersten Schuppenstromes in einen auf einer zweiten Förderstrecke geförderten, schräg zum ersten Schuppenstrom verlaufenden zweiten Schuppenstrom, mit Mit¬ tein zum geraden Ausrichten des zweiten Schuppenstroms in seiner Förderrichzung.The invention relates to a device for transferring a first scale stream, which is conveyed on a first conveyor line and is formed from printed products, into a second scale stream, which is conveyed on a second conveyor path and runs obliquely to the first scale stream, with means for the straight alignment of the second scale stream in its funding direction.
Einrichtungen dieser Art sind aligemein bekannt. Zum Aus¬ richten der Druckprodukte des zweiten Schuppenstroms weisen diese ein Seitenblech auf, das parallel zur zweiten Förder- strecke verläuft und an dem die Druckprodu -e seitlich ni einem Rand anliegend entlanσgleiten. Anstelle des Seiten¬ bleches werden zuweilen auch Bürsten oder Rollen verwendet. 3estehen -nun die Druckprodukte aus ineinandergefaiteten und seitlich zueinander versetzten Druckprodukten, so werden durch den Anschlag am Seitenblech die Ränder der Druckpro¬ dukte beschädigt und auch die ineinandergefaltetεn Druck¬ produkte gegeneinander verschoben. Die weitere anschiies- sende Behandlung des Schuppenstromes kann dadurch gestört werden.Devices of this type are generally known. To align the printed products of the second stream of shingles, they have a side plate which is parallel to the second conveyor The route runs and along which the printed products glide alongside an edge. Brushes or rollers are sometimes used instead of the side plate. If the printed products now consist of nested and laterally offset printed products, the edges of the printed products will be damaged by the stop on the side plate and the folded printed products will also be displaced relative to one another. This can interfere with the subsequent treatment of the shingled stream.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der genannten Art zu schaffen, welche die genannten Nach¬ teile vermeidet und die somit eine wesentlich schonendere Behandlung von im Schuppenstrom geförderten Druckprodukten erlaubt. Die Einrichtung soll trotzdem funktionssicher und günstig in der Herstellung und im Unterhalt sein.The invention has for its object to provide a device of the type mentioned, which avoids the disadvantages mentioned and thus allows a much gentler treatment of printed products conveyed in the shingled stream. The device should still be reliable and inexpensive to manufacture and maintain.
Die Aufgabe ist bei einer gattungsgemässen Einrichtung da¬ durch gelöst, dass zwischen der ersten und der zweiten För¬ derstrecke eine nach unten führende Stufe angeordnet ist und dass die Mittel zum geraden Ausrichten des zweiten Schuppenstromes den ersten und den zweiten Schuppenstrom von oben lenken. Bei der erfindungsgemässen Einrichtung werden der erste und der zweite Schuppenstrom von oben ge¬ lenkt, so dass ein seitliches Anschlagblech oder derglei¬ chen nicht erforderlich ist. Die seitlichen Ränder des zweiten Schuppenstroms sind damit frei und werden nicht be¬ aufschlagt. Die Ränder der Druckprodukte können somit nicht beschädigt und auch die seitliche Versetzung der Druckpro¬ dukte nicht verändert .werden.. Zwischen den beiden Förder¬ strecken ist eine Stufe angeordnet, welche den zweiten Schuppenstrom in diesem 3ereich vorübergehend auffächert. Es hat sich nun überraschend gezeigt, dass diese Auffäche¬ rung die Lenkung der Druckprodukte wesentlich erleichtert und bei grδsseren Druckprodukten sogar erst ermöglicht. Vermutlich liegt das daran, dass im 3ereich der Stufe die Druckprodukte beweglicher sind und Querkräfte hier nicht zu einer Störung des Schuppenstroms führen können. Wesentlich ist somit, dass die Richtung und seitliche genaue Bündig¬ keit der umgelenkten Druckprodukte unabhängig von der För- dergeschwindigkeit nicht verändert werden. Weitere vorteil¬ hafte Merkmale ergeben sich aus den abhängigen Pa¬ tentansprüchen, der Beschreibung und der Zeichnung.The object is achieved in a generic device by arranging a step leading downwards between the first and the second conveying section and by the means for straightening the second stream of shed guiding the first and second stream of shed from above. In the device according to the invention, the first and the second scale flow are directed from above, so that a lateral stop plate or the like is not necessary. The side edges of the second scale stream are thus free and are not applied. The edges of the printed products can thus not be damaged and the lateral displacement of the printed products cannot be changed. A step is arranged between the two conveying lines, which temporarily fanned out the second stream of flakes in this area. It has now surprisingly been found that this broadening considerably facilitates the control of the printed products and even enables them in the case of larger printed products. This is presumably due to the fact that the printed products are more mobile in the area of the stage and lateral forces cannot lead to a disruption of the scale flow here. It is therefore essential that the direction and exact lateral flushness of the deflected printed products are not changed regardless of the conveying speed. Further advantageous features result from the dependent patent claims, the description and the drawing.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend an¬ hand der Zeichnung näher erläutert. Es zeigen:An embodiment of the invention is explained in more detail below with reference to the drawing. Show it:
Fig. 1 eine Teilansicht einer erfindungsgemässen Einrich¬ tung, und1 is a partial view of a device according to the invention, and
Fig. 2 eine weitere Teilansicht der erfindungsgemässen Einrichtung. _ _Fig. 2 shows a further partial view of the device according to the invention. _ _
Die Einrichtung weist eine erste Förderstrecke 1 mit wenig¬ stens zwei parallel zueinander in Richtung des Pfeiles 17 verlaufenden Förderbändern 6 auf. Die 3änder 6 sind in an sich bekannter Weise durch einen hier nicht gezeigten An¬ trieb mittels einer Welle 16 angetrieben und am vorderen Ende jeweils um eine Rolle 8 geführt. Die endlosen 3änder 6 sind teleskopisch verstellbar, derart, dass eine vordere Kante K der Förderstrecke parallel verstellbar ist. Solche Teleskopbänder sind an sich gut bekannt. Mit der ersten Förderstrecke 1 kann ein Schuppenstrom 2 aus Druckprodukten 2a in Richtung des Pfeiles 17 gefördert werden. Die Druck¬ produkte 2a sind beispielsweise Zeitungen oder Zeitschrif¬ ten, die aus seitlich versetzt angeordneten Teilen beste¬ hen. Wie ersichtlich, wird der Schuppenstrom im wesentli¬ chen diagonal zu den Druckprodukten 2a gefördert. Anstelle der 3änder 6 sind auch andere geeignete Fördermittel zum Fördern des Schuppenstroms 2 denkbar.The device has a first conveyor section 1 with at least two conveyor belts 6 running parallel to one another in the direction of arrow 17. The 3 countries 6 are driven in a manner known per se by a drive (not shown here) by means of a shaft 16 and are each guided around a roller 8 at the front end. The endless 3 countries 6 are telescopically adjustable in such a way that a front edge K of the conveyor line can be adjusted in parallel. Such telescopic tapes are well known per se. With the first conveyor section 1, a shingled stream 2 of printed products 2a can be conveyed in the direction of arrow 17. The printed products 2a are, for example, newspapers or magazines which consist of parts which are arranged laterally offset. As can be seen, the scale flow is conveyed essentially diagonally to the printed products 2a. Instead of the 3 countries 6, other suitable conveying means for conveying the scale flow 2 are also conceivable.
Etwas hinter der Kante K sind drei Pressrollen 5 jeweils über einem Band 6a angeordnet und an Wellen 5a gelagert. Die Wellen 5a sind an einem Gestell 4 in Längsrichtung der Bänder 6 versteilbar gelagert. Die Rollen 5 können somit beim Verstellen der Umlenkrollen 8 ebenfalls um den glei¬ chen Betrag und auch unabhängig von den Rollen 8 verstellt werden. Mit einer hier nicht gezeigten Feder sind die Rol¬ len 5 am Schuppenstrom 2 oberseitig bzw. an den Bändern 6a angepresst. Die Rollen 5 sind somit Pressrollen. Durch die Adhäsion zwischen den Rollen 5 und dem Schuppenstrom bzw. den 3ändern 6 werden die Rollen 5 um die Welle 5a in Rich¬ tung des Pfeiles 21 bewegt. Denkbar ist jedoch auch eine Ausführung, bei welcher die Rollen 5 über die Weile 5a an¬ getrieben sind. Die Umfangsgeschwindigkeiten der Rollen 5 sind jedenfalls gleich und gleich der Fördergeschwindigkeit des Schuppenstromes 2. Die Rollen 5 haben die Wirkung, dass die Druckprodukte 2a über einer Stufe 20 unter ebenfalls passiv mitlaufende Rollen 10 gelenkt werden. Zwischen den Rollen 5 und 10 besteht eine Stufe 20, in welcher die Druckprodukte aufgefächert werden. In der Fig. 1 sind auf¬ gefächerte Druckprodukte mit dem 3ezugszeichen 3b bezeich¬ net. Neben jeder Rolle 5 ist ein gebogenes, an einem orts¬ festen Gestell 9 angebrachtes Rohr 24 angeordnet. Die Rohre 24 führen die Druckprodukte 2a über die Stufe 20 nach unten σeσen die Rollen 10.Slightly behind the edge K, three press rollers 5 are each arranged above a belt 6a and supported on shafts 5a. The shafts 5a are mounted on a frame 4 so that they can be distributed in the longitudinal direction of the bands 6. The rollers 5 can thus also be adjusted by the same amount when adjusting the deflection rollers 8 and also independently of the rollers 8. With a spring, not shown here, the rollers 5 are pressed on the scale stream 2 on the top side or on the belts 6a. The rollers 5 are thus press rollers. Through the Adhesion between the rollers 5 and the scale flow or the 3 other 6, the rollers 5 are moved around the shaft 5a in the direction of arrow 21. However, an embodiment is also conceivable in which the rollers 5 are driven over the period 5a. In any case, the peripheral speeds of the rollers 5 are the same and equal to the conveying speed of the shingled stream 2. The rollers 5 have the effect that the printed products 2a are steered over a step 20 under rollers 10 which are also passively moving. Between the rollers 5 and 10 there is a step 20 in which the printed products are fanned out. In FIG. 1, fanned out printed products are designated with the reference number 3b. In addition to each roller 5 there is a bent tube 24 attached to a fixed frame 9. The tubes 24 guide the printed products 2a down the step 20 and the rollers 10.
Die Rollen 10 gehören zu einer zweiten Förderstrecke 23, welche die Druckprodukte in Richtung des Pfeiles 18 för¬ dert. Aus dem Druckprodukt 2a wird auf der zweiten Förder¬ strecke 23 ein zweiter Schuppenstrom 3 gebildet, der bezüg¬ lich des ersten Schuppenstromes 2 beispielsweise um 45° um¬ gelenkt ist. Die Druckprodukte 3a dieses umgelenkten Schup¬ penstroms 3.weisen Kanten 3c auf, die geradlinig zueinander und parallel zur Förderrichtung 18 aufgerichtet sind. Die Förderstrecke 23 weist ein endloses vergleichsweise breites 3and 25 auf, das mittels einer Welle 13 angetrieben und um eine parallele Welle 14 geführt ist. Die Förderge¬ schwindigkeit der Förderstrecke 23 ist gleich der Förderge— schwindigkeit der ersten Förderstrecke 1 in Richtung des Pfeiles 18. Die Rollen 10 sind seitlich verstellbar an ei¬ ner Welle 12a eines Gestells 12 gelagert. Mittels einer ebenfalls am Gestell angebrachten Blattfeder 11 werden die Rollen 10 nach unten oberseitig am Schuppenstrom 3 ange¬ presst. Die Welle 12a ist an einer Stange 12b des Gestells 12 befestigt und in den Richtungen des Doppelpfeiles 21 verstellbar. Gleichzeitig sind die Rollen 10 in den Rich¬ tungen des Doppelpfeiles 22 verschiebbar. Die Rollen 10 sind ebenfalls Anpressrollen und werden vorzugsweise passiv durch Adhäsion entsprechend der Fördergeschwindigkeit des 3andes 25 auf der Welle 12a gedreht. Die Rollen 10 erfassen die von den Rollen 5 gelenkten Druckprodukte 3b und pressen diese am oberen Trum 25a des Bandes 25 an. Durch die ent¬ sprechende Adhäsion zwischen dem Trum 25a und den Druck¬ produkten 3a ist gewährleistet, dass diese die Bewegungs¬ richtung des Bandes 25 übernehmen und entsprechend umge¬ lenkt werden. Die Rollen 10 verhindern zudem, dass die Druckprodukte 3a auf dem oberen Trum 25a seitlich verscho¬ ben werden können. Damit ist gewährleistet, dass die Ränder 3c des Schuppenstromes 3 wie oben erwähnt geradlinig zuein¬ ander ausgerichtet sind. Wesentlich ist hierbei, dass die Ränder 3c zumindest während der Umlenkung seitlich nicht beaufschlagt sind. Dies gilt ebenfalls für die gegenüber¬ liegenden Ränder 3d. Die Rollen 5 und 10 bilden somit Mit¬ tel zur Lenkung der Druckprodukte. Die Rollen 5 und 10 kön¬ nen- durch andere geeignete Anpressmittel, beispielsweise durch Bänder ersetzt sein.The rollers 10 belong to a second conveyor section 23 which conveys the printed products in the direction of the arrow 18. From the printed product 2a, a second scale stream 3 is formed on the second conveyor section 23, which is deflected by 45 ° with respect to the first scale stream 2, for example. The printed products 3a of this deflected stream 3 have edges 3c which are aligned in a straight line to one another and parallel to the conveying direction 18. The conveyor section 23 has an endless, comparatively wide shaft 25, which is driven by means of a shaft 13 and is guided around a parallel shaft 14. The conveying speed of the conveying path 23 is equal to the conveying speed of the first conveying path 1 in the direction of the arrow 18. The rollers 10 are laterally adjustable on a shaft 12a of a frame 12. By means of a leaf spring 11 also attached to the frame, the rollers 10 are pressed downward on the top of the scale stream 3. The shaft 12a is fastened to a rod 12b of the frame 12 and is adjustable in the directions of the double arrow 21. At the same time, the rollers 10 can be displaced in the directions of the double arrow 22. The rollers 10 are also pressure rollers and are preferably rotated passively by adhesion in accordance with the conveying speed of the belt 25 on the shaft 12a. The rollers 10 grip the printed products 3b guided by the rollers 5 and press them onto the upper run 25a of the belt 25. The corresponding adhesion between the strand 25a and the printed products 3a ensures that these take over the direction of movement of the belt 25 and are deflected accordingly. The rollers 10 also prevent the printed products 3a from being laterally displaceable on the upper run 25a. This ensures that the edges 3c of the scale stream 3 are aligned in a straight line to one another, as mentioned above. It is important here that the edges 3c do not move laterally, at least during the deflection are acted upon. This also applies to the opposite edges 3d. The rollers 5 and 10 thus form means for steering the printed products. The rollers 5 and 10 can be replaced by other suitable pressing means, for example by belts.
Der Abstand A zwischen den Rolien 5 und 10 ist auf die Länge der Dr ckprocuktε 2a abgestimmt. Der Abstand A kann gleich der Länge eines Druckproduktes 2a sein. Dieser Ab¬ stand kann aber auch kürzer sein, so dass ein Druckprodukt im 3ereich der Stufe 20 sowohl von den Rollen 5 als auch von den Rollen 10 erfasεt ist. Der Abstand A kann somit et¬ was grösser oder kleiner sein als die Länge der Druckpro¬ dukte. Durch Verschieben der Welle 12a auf der Stange 12b kann dieser Abstand genau eingestellt und fixiert werden.The distance A between the rolls 5 and 10 is matched to the length of the printing product 2a. The distance A can be equal to the length of a printed product 2a. This distance can, however, also be shorter, so that a printed product in the area of stage 20 is covered by both the rollers 5 and the rollers 10. The distance A can thus be somewhat larger or smaller than the length of the printed products. By moving the shaft 12a on the rod 12b, this distance can be set and fixed precisely.
Mit der erfindungsgemässen Einrichtung können Druckprodukte mit unterschiedlichem Format umgelenkt werden. Beispiels¬ weise sind auch Druckprodukte mit dem in Fig. 2 durch die strichpunktierten Linien angedeuteten Format F umlenkbar. Durch eine Verschiebung der Kante K kann bei allen Formaten der Schuppenstrom 3 seitlich in der einen oder anderen Richtung versetzt werden. Entsprechend werden dann die Rol¬ len 10 durch eine entsprechende Verschiebung auf der Welle 12a ersetzt. In der eingestellten Position sind die Rollen 10 selbstverständlich durch hier nicht gezeigte Mittel ge¬ gen eine axiale Verschiebung fixierbar. Die für die Lage- rung und Halterung der Förderstrecken 1 und 23 erforderli¬ chen Gestelle 4, 9 und 15 sind hier lediglich andeutungs¬ weise gezeigt, da der Aufbau solcher Gestelle für den Fach¬ mann naheliegend ist. Ebenfalls sind geeignete Antriebsvor¬ richtungen für die 3änder 6 und 12 für den Fachmann gut be¬ kannt und brauchen hier nicht erläutert zu werden. With the device according to the invention, printed products with different formats can be deflected. For example, printed products with the format F indicated by the dash-dotted lines in FIG. 2 can also be deflected. By shifting the edge K, the shingled stream 3 can be displaced laterally in one or the other direction in all formats. Correspondingly, the rollers 10 are then replaced by a corresponding displacement on the shaft 12a. In the set position, the rollers 10 can of course be fixed against axial displacement by means not shown here. The for the location The mounting and mounting of the conveyor lines 1 and 23 required frames 4, 9 and 15 are only indicated here as the structure of such frames is obvious to a person skilled in the art. Suitable drive devices for the 3 countries 6 and 12 are likewise well known to the person skilled in the art and need not be explained here.
