Description
Die Erfindung betrifft eine Vorrichtung zum Aufteilen eines Schuppenstromes aus jeweils übereinanderliegenden Nutzen in zwei durch Abheben gebildete Teilströme mit zwei Fördereinrichtungen in Form von Transportbändern.The invention relates to a device for dividing a stream of shingles from superimposed benefits into two partial streams formed by lifting with two conveyors in the form of conveyor belts.
Im Druckereiwesen kommt es in der Praxis häufig vor, daß aus einem Papierbogen zwei (oder mehr) sogenannte Nutzen hergestellt werden. Nachdem dieser Papierbogen, z. B. in einer Offsetdruckmaschine, entsprechend bedruckt worden ist, wird er mehrfach gefaltet und geschnitten, sodaß im Endeffekt zwei gefaltete Nutzen -jeweils aus einem halben ursprünglichen Bogen bestehend - übereinanderliegen. Dabei kommt es vor, daß der obere Nutzen in bezug auf den unteren Nutzen verkehrt liegt, d. h., daß z. B. der untere die Faltung links und der obere die Faltung rechts hat.In the printing industry, it often happens in practice that two (or more) so-called benefits are produced from one sheet of paper. After this paper sheet, e.g. B. in an offset printing machine, has been appropriately printed, it is folded and cut several times, so that in the end two folded benefits - each consisting of half an original sheet - lie on top of each other. It happens that the upper benefit is wrong in relation to the lower benefit, i. that is, e.g. B. the lower one has the fold on the left and the upper one has the fold on the right.
Da es gewöhnlich notwendig ist, daß die Nutzen einheitlich übereinanderliegen, ist es nötig, die beiden verkehrt übereinanderliegenden Nutzen zu trennen und getrennt zu sammeln. Dieses Trennen bzw. Auseinanderlegen wird derzeit händisch durchgeführt und in den Druckereien als "Auszupfen" bezeichnet. Dieses Auszupfen bedingt klarerweise relativ hohe Personalkosten.Since it is usually necessary for the benefits to be uniformly one above the other, it is necessary to separate the two wrongly superimposed benefits and to collect them separately. This separation or disassembly is currently carried out manually and is called "plucking" in the printing works. This plucking clearly requires relatively high personnel costs.
Während gemäß der CH-A-655 489 die den Oberbegriff des Anspruchs 1 deckt, ein zulaufender Schuppenstrom, aus zwei Formationen vorausgesetzt wird, die bereits seitlich etwas zueinander versetzt sind, geht die Erfindung von dem in der Praxis häufig anzutreffenden Zustand aus, daß in einem Schuppenstrom die Nutzen (z. B. paarweise) deckungsgleich übereinanderliegen.While according to CH-A-655 489, which covers the preamble of
Die weiters bekannte CH-A-663 604 betrifft eine Umlenkeinrichtung für einen Schuppenstrom, insbesondere von in geschuppter Lage zu transportierenden Heften oder Bogen (Nutzen). Dabei schließen mehrere Förderstrecken aneinander. Eine Teilstrecke ist als Weiche ausgebildet und abklappbar sowie in der Förderrichtung umschaltbar. Damit läßt sich beispielsweise eine Umlenkung des Schuppenstromes um 180° erreichen.The further known CH-A-663 604 relates to a deflection device for a shingled stream, in particular of booklets or sheets to be transported in a shingled position (benefit). Several conveyor lines are connected. A section is designed as a switch and can be folded down and switched in the conveying direction. This can be used, for example, to deflect the scale flow by 180 °.
Es ist Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Aufteilen eines Schuppenstromes aus übereinanderliegenden Nutzen zu schaffen, die insbesondere auch deckungsgleich übereinanderliegende Nutzen automatisch trennen kann.It is an object of the present invention to provide a device for dividing a stream of shingles from superimposed uses, which can in particular also automatically separate superimposed uses.
Diese Aufgabe wird durch eine Vorrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß über dem den Schuppenstrom der Nutzen tragenden ersten Transportband das zweite Transportband, der Oberfläche der Nutzen benachbart und mit einer mit Unterdruck beaufschlagbaren Lochperforierung ausgebildet, vorgesehen ist und daß die Transportrichtungen der Transportbänder einen spitzen Winkel zueinander einschließen.This object is achieved according to the invention by a device of the type mentioned above in that the Shingled stream of the first conveyor belt carrying the panels, the second conveyor belt, which is adjacent to the surface of the panels and is provided with perforated perforations which can be subjected to negative pressure, is provided and that the directions of transport of the conveyor belts form an acute angle to one another.
Wenn die übereinanderliegenden Nutzen auf dem unteren ersten Transportband zu der Stelle kommen, wo das obere zweite Transportband beginnt, wird der obere Nutzen von letzterem angesaugt und seitlich weggezogen, sodaß die beiden Nutzen getrennt werden.When the superimposed panels on the lower first conveyor belt come to the place where the upper second conveyor belt begins, the upper panel is sucked in by the latter and pulled away to the side, so that the two panels are separated.
Zweckmäßig ist der Abstand zwischen den beiden Transportbändern einstellbar. Er soll zweckmäßigerweise so eingestellt werden, daß er geringfügig größer als die Höhe der übereinanderliegenden Nutzen ist, sodaß einerseits diese leicht zwischen die Transportbänder gelangen können, anderseits aber der obere Nutzen leicht angesaugt werden kann.The distance between the two conveyor belts is expediently adjustable. It should expediently be set so that it is slightly larger than the height of the superimposed benefits, so that on the one hand they can easily get between the conveyor belts, but on the other hand the upper benefit can be easily sucked in.
Gemäß einer Ausführungsform der Erfindung ist das untere erste Transportband zumindest doppelt so breit wie das obere zweite Transportband und ist das obere zweite Transportband vollständig oder wenigstens mit dem Bereich, in dem die Lochperforierung mit Unterdruck beaufschlagt wird, innerhalb der Breite des unteren ersten Transportbandes angeordnet. Dadurch wird erreicht, daß der obere Nutzen, nachdem er seitlich versetzt wurde, wieder auf dem unteren ersten Transportband abgelegt wird, sodaß schließlich die beiden Nutzen nebeneinander weitertransportiert und gestapelt werden können.According to one embodiment of the invention, the lower first conveyor belt is at least twice as wide as the upper second conveyor belt and the upper second conveyor belt is arranged completely or at least within the width of the lower first conveyor belt with the area in which the perforated perforation is pressurized. It is thereby achieved that the upper panel, after it has been displaced laterally, is put down again on the lower first conveyor belt, so that the two panels can finally be transported next to one another and stacked.
In diesem Fall ist es zweckmäßig, wenn das untere erste Transportband in dem Teil seiner Breite, wo das obere zweite Transportband beginnt, eine mit Unterdruck beaufschlagbare Lochperforierung aufweist. Dadurch wird der untere Nutzen angesaugt, sodaß er nicht leicht verschoben werden kann; der obere Nutzen wird hingegen vom unteren ersten Transportband nicht angesaugt, weil er auf dem unteren Nutzen liegt, sodaß er vom oberen zweiten Transportband seitlich versetzt werden kann.In this case, it is expedient if the lower first conveyor belt has a perforated perforation which can be subjected to negative pressure in the part of its width where the upper second conveyor belt begins. This draws in the bottom panel so that it cannot be easily moved; the upper panel, however, is not sucked in by the lower first conveyor belt because it lies on the lower panel, so that it can be moved laterally by the upper second conveyor belt.
Während und nach der seitlichen Versetzung liegt der obere Nutzen zwar in zunehmendem Maß direkt auf dem unteren ersten Transportband auf, jedoch hat dieses dort normalerweise keine Lochperforierung, sodaß die seitliche Bewegung nicht behindert wird. Ist dort eine Lochperforierung vorgesehen, um den oberen Nutzen nach dem seitlichen Versetzen auf dem unteren ersten Transportband zu fixieren, dann sollte die Lochperforierung im Bereich des oberen zweiten Transportbandes nicht mit Unterdruck beaufschlagt sein, damit das seitliche Versetzen nicht behindert wird.During and after the lateral displacement, the upper benefit lies to an increasing extent directly on the lower first conveyor belt, but this usually has no perforated perforation there, so that the lateral movement is not hindered. If there is a perforation in the hole to fix the upper panel on the lower first conveyor belt after moving it laterally, then the perforation should be in the area of the upper second The conveyor belt must not be subjected to negative pressure so that the lateral displacement is not hindered.
Günstigerweise ist die Geschwindigkeit des oberen zweiten Transportbandes in bezug auf die des unteren ersten Transportbandes einstellbar. Die Geschwindigkeit wird je nachdem, wie stark die jeweils übereinanderliegenden Nutzen mit den nächsten übereinanderliegenden Nutzen überlappen, eingestellt. Je stärker sie überlappen, umso schneller soll sich das obere zweite Transportband bewegen, damit die oberen Nutzen mit einer ausreichend großen Fläche am oberen zweiten Transportband anliegen.The speed of the upper second conveyor belt is advantageously adjustable in relation to that of the lower first conveyor belt. The speed is set depending on the extent to which the superimposed benefits overlap with the next superimposed benefits. The more they overlap, the faster the upper second conveyor belt should move so that the upper panels lie with a sufficiently large area on the upper second conveyor belt.
Zum besseren Verständnis der Erfindung wird ein Ausführungsbeispiel anhand der Zeichnungen näher erläutert.For a better understanding of the invention, an embodiment is explained in more detail with reference to the drawings.

Wie aus Fig. 1 ersichtlich, besteht die erfindungsgemäße Vorrichtung im wesentlichen aus einem unteren Transportband 1 und einem oberen Transportband 2, wobei die Transportrichtungen der beiden Transportbänder miteinander einen spitzen Winkel einschließen. Gemäß den Fig. 2 und 3 ist das eine Lochperforierung 15 aufweisende obere Transportband 2 über Umlenkrollen 3 geführt, die in einem Grundgestell 8 gelagert sind und von denen eine von einem potentiometergesteuerten Getriebemotor 4 angetrieben ist. Um einen Schlupf des Transportbandes 2 zu vermeiden, ist eine Anpreßrolle 5 vorgesehen, die gegen die angetriebene Umlenkrolle 3 drückt. In dem vom Transportband 2 umschlossenen Raum ist ein zweigeteilter, Ansaugöffnungen 7 aufweisender Vakuumkasten 6 angeordnet. Das in den Fig. 4 und 5 gezeigte untere, einseitig eine Lochperforierung 16 aufweisende Transportband 1 ist auch über Umlenkrollen 9 geführt, von denen eine mechanisch vom nicht dargestellten Paketausleger angetrieben ist. Im vom Transportband 1 umschlossenen Raum ist ein eine Ansaugöffnung 13 aufweisender Saugkasten 10 angeordnet.1, the device according to the invention essentially consists of a
Von den in Richtung des Pfeiles 14 auf das untere Transportband 1 gelangenden, bündig übereinanderliegenden Doppelnutzen 11, 12 wird der obere Nutzen 11 vom oberen Transportband 2 aufgrund der durch dieses ausgeübten Saugwirkung vom unteren Nutzen 12 abgehoben und seitlich wegtransportiert. Der untere Nutzen 12 bleibt aufgrund der durch das untere Transportband 1 ausgeübten Saugwirkung auf letzterem liegen. Am Ende des oberen Transportbandes 2 wird der obere Nutzen 11 seitlich versetzt auf das untere Transportband 1 abgelegt.Of the
