Description

Einrichtung zum Fördern und Trennen von gefalteten Druckprodukten Device for conveying and separating folded printed products
Die Erfindung betrifft eine Einrichtung zum Fördern und Trennen von gefalteten Druckprodukten, die auf einer Förderanlage in einem Schuppenstrom zugeführt werden, wobei wenigstens zwei Druckprodukte seitlich gegeneinander versetzt sind und seitlich des Schuppenstromes je ein Förderorgan angeordnet ist und wobei diese Förderorgane auseinanderlaufen und die Druckprodukte auseinanderziehen. The invention relates to a device for conveying and separating folded printed products, which are fed on a conveyor system in a shingled stream, at least two printed products being laterally offset from one another and a conveying member being arranged to the side of the shingled stream, and these conveying members diverge and pull the printed products apart.
Eine Einrichtung dieser Gattung ist aus der CH-A-634 530 bekannt. Diese weist zwei parallele Förderorgane auf, die als Ketten ausgebildet sind und zum Erfassen der Ränder der Druckprodukte Klemmrollen besitzen. Zum Auseinanderziehen der ineinandergefalzten Druckprodukte werden die Ketten in Schienen auseinandergeführt. Eine ähnliche Einrichtung ist aus der DE-A-24 17 614 bekannt. Bei dieser sind zum Fassen und Auseinanderziehen der ineinandergefalzten Druckprodukte quer 2ur Förderrichtung bewegbare Greifer vorgesehen. Beide Einrichtungen sind jeweils auf eine bestimmte Breite des Schuppenstromes eingestellt. Eine Umrüstung auf eine andere Breite wäre sehr aufwendig. A device of this type is known from CH-A-634 530. This has two parallel conveyor elements, which are designed as chains and have pinch rollers for grasping the edges of the printed products. In order to pull the folded printed products apart, the chains are moved apart in rails. A similar facility is there known from DE-A-24 17 614. This gripper is provided for gripping and pulling apart the folded printed products transversely to the conveying direction. Both devices are each set to a certain width of the scale flow. A change to a different width would be very expensive.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der genannten Gattung zu schaffen, mit der Schuppenströme unterschiedlicher Breiten gefördert werden können. Die Umstellung soll sehr einfach und schnell möglich sein. Zudem soll sich die Einrichtung auch zum Trennen von Schuppenströmen mit mehr als zwei ineinandergefalzten oder übereinanderliegenden Druckprodukten eignen. Die Aufgabe ist bei der gattungsgemässen Einrichtung dadurch gelöst, dass das eine erste Förderorgan eine Lücke aufweist, in welche das andere zweite Förderorgan mit einem vorderen Ende eingreift und dieses schräg zum ersten Förderorgan fördert und ein unteres Auszugsband und ein obere Auszugsband aufweist und dass das obere Auszugsband an seinem vorderen Ende teleskopisch in Förderrichtung des zweiten Förderorgans verstellbar ist. The invention has for its object to provide a device of the type mentioned, with the shingled streams of different widths can be promoted. The changeover should be possible very easily and quickly. In addition, the device should also be suitable for separating shingled streams with more than two folded or overlapping printed products. The object is achieved in the generic device in that the first conveying member has a gap into which the other second conveying member engages with a front end and conveys it obliquely to the first conveying member and has a lower pull-out belt and an upper pull-out belt and that the upper one Pull-out belt at its front end is telescopically adjustable in the conveying direction of the second conveying member.
Bei der erfindungsgemässen Einrichtung muss zur Anpassung an die Breite des zu trennenden Schuppenstromes lediglich das vordere Ende des oberen Auszugsbandes verstellt werden. Je nach Breite des Schuppenstromes greift das vordere Ende des oberen Auszugsbandes mehr oder weniger tief in die Lücke des ersten Förderorgans ein. Beim Auseinanderziehen werden die Druckprodukte nicht geknickt und damit schonender behandelt als bisher üblich. Zudem ist die Einrichtung wesentlich kostengünstiger und weist einen geringeren Platzbedarf auf. Mit den beiden Auszugsbändern werden die aus dem Schuppenstrom abzuziehenden Druckprodukte am vorstehenden Rand gefasst und schräg zum ersten Förderorgan zwischen den beiden Auszugsbändern zu einem weiteren Förderorgan gefördert. Zwischen den beiden Auszugsbändern werden die Druckprodukte flächig gefasst und sind dadurch während des ganzen Ausziehvorganges sicher geführt. Dadurch können auch Schuppenströrae getrennt werden, bei denen die Druckprodukte sehr unübliche Formate aufweisen. Zudem ist gewährleistet, dass elektrostatische Haftungen zwischen den Druckprodukten nicht zu einer Störung führen. Es hat sich gezeigt, dass bei der erfindungsgemässen Einrichtung der Versatz wesentlich kleiner sein kann als der bisher übliche Versatz der ineinandergefalzten oder übereinander angeordneten Druckprodukte. Möglich ist auch die Aufteilung eines Schuppenstromes, der aus zwei oder mehr übereinander und seitlich versetzt angeordneten Teiischuppenströmen besteht. Dadurch kann die Förderkapazität kostengünstig erhöht werden. Weitere vorteilhafte Merkmaie ergeben sich aus den abhängigen Ansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung. Ein Ausführungsbeispiel der Erfindung ist nachfolgend anhand der Zeichnung näher erläutert. Es zeigen: In the device according to the invention, only the front end of the upper pull-out band has to be adjusted to adapt to the width of the shingled stream to be separated. Depending on the width of the stream of shingles, the front end engages the upper pull-out belt more or less deep into the gap of the first conveyor. When pulled apart, the printed products are not kinked and are therefore treated more gently than was previously the case. In addition, the device is significantly less expensive and requires less space. With the two pull-out belts, the printed products to be withdrawn from the stream of shingles are gripped at the projecting edge and conveyed diagonally to the first conveying member between the two pull-out belts to a further conveying member. The printed products are held flat between the two pull-out belts and are thus safely guided during the entire pull-out process. As a result, streams of shingles can also be separated in which the printed products have very unusual formats. It also ensures that electrostatic adhesion between the printed products does not lead to a malfunction. It has been shown that the offset in the device according to the invention can be significantly smaller than the previously usual offset of the folded or stacked printed products. It is also possible to divide a shingled stream consisting of two or more partial shingled streams arranged one above the other and laterally offset. As a result, the production capacity can be increased cost-effectively. Further advantageous features result from the dependent claims, the following description and the drawing. An embodiment of the invention is explained below with reference to the drawing. Show it:

Die Figuren 1 und 2 zeigen ein erstes geradlinig verlaufendes Förderorgan 1 und ein zweites ebenfalls geradlinig verlaufendes Förderorgan 2. Diese Förderorgane 1 und 2 sind mitteis eines Motors 23 über Wellen 4 und 5 angetrieben. Figures 1 and 2 show a first rectilinear conveyor element 1 and a second also rectilinear conveyor element 2. These conveyor elements 1 and 2 are driven by means of a motor 23 via shafts 4 and 5.
Das Förderorgan 1 weist ein vergleichsweise breites Anpressband 7 sowie Teiibänder 8 und 10 auf. Die Teiibänder 8 sowie das Band 7 sind von der gemeinsamen Welle 5 angetrieben. Das hier nicht gezeigte andere Ende des Bandes 7 ist um eine hier nicht gezeigte Weile herumgeführt. Die Bänder 8 sind wesentlich kürzer als das Band 7 und um eine Welle 6 geführt, die parallel zur Welle 5 verläuft. Zwischen den Bändern 8 und 10 besteht eine Lücke 11, in welche das zweite Förderorgan 2 eingreift.. Die Bänder 10 sind um Rollen 12 geführt, die wie ersichtlich in Förderrichtung gesehen versetzt angeordnet sind und zwar so, dass die Lücke mit zunehmendem Abstand zum Band 7 weiter wird. Entsprechend stufenförmig ist auch das vordere Ende des zweiten Förderorgans 2 ausgebildet. Die Bänden 7, 8 und 10 sind wie erwähnt gemeinsam angetrieben und die oberen Trums verlaufen in der gleichen horizontalen Ebene und in der gleichen durch den Pfeil 24 angegebenen Richtung. Ueber dem Band 7 ist ein Anpressbalken 21 angeordnet, der mit dem Band 7 zusammenarbeitet um einen Schuppenstrom S am einen Rand zu fassen. Dieser Pressbalken 21 weist gemäss Fig. 4 ebenfalls umlaufende Bänder 22 auf, deren unterer Trum in gleicher Richtung und mit gleicher Geschwindigkeit wie der obere Trum des Bandes 7 bewegt wird. Anpressbalken dieser Art sind bekannt. The conveyor element 1 has a comparatively wide pressure belt 7 and partial belts 8 and 10. The partial belts 8 and the belt 7 are driven by the common shaft 5. The other end of the band 7, not shown here, is guided around for a while, not shown here. The bands 8 are much shorter than the band 7 and guided around a shaft 6 which runs parallel to the shaft 5. Between the belts 8 and 10 there is a gap 11, in which the second conveyor element 2 engages. The belts 10 are guided around rollers 12 which, as can be seen, are arranged offset in the conveying direction, in such a way that the gap increases with increasing distance from the belt 7 continues. The front end of the second conveying element 2 is also designed in a step-like manner. The volumes 7, 8 and 10 are, as mentioned, driven together and the upper runs run in the same horizontal plane and in the same direction indicated by the arrow 24. A pressure bar 21 is arranged above the belt 7 and works together with the belt 7 in order to grasp a scale stream S at one edge. 4, this press beam 21 also has revolving belts 22, the lower strand of which is moved in the same direction and at the same speed as the upper strand of the belt 7. Pressure bars of this type are known.
Das zweite Förderorgan 2 weist ein unteres Auszugsband 13 und ein oberes Auszugsband 14 auf, die schräg und vorzugsweise um etwa 45° geneigt zum ersten Förderogran 1 verlaufen. Die Förderrichtung des Förderorgans 2 ist durch den Pfeil 25 angegeben. Die Fördergeschwindigkeit des Förderorgans 1 ist so gewählt, dass die Geschwindigkeitskomponente in der Förderrichtung des Förderorgans 1 gieich gross ist wie die Fördergeschwindigkeit des Förderorgans 1. Das untere Auszugsband 13 besteht aus sechs parallel zueinander angeordneten Teilbändern 13c die jeweils am vorderen Ende um eine Rolle 15 laufen. Diese Rollen 15 sind wie aus Fig. 1 ersichtlich, entsprechend der Lücke 11 in Förderrichtung versetzt angeordnet. Zwei parallel nebeneinander angeordnete Bänder 13a arbeiten jeweils mit einem oberen Band 14a zum Erfassen und Ausziehen von Druckprodukten 3 aus dem Schuppenstrom S zusammen. Die Bänder 14a sind jeweils um eine vordere Umlenkrolle 16 und ümlenkrollen 17 geführt. Für eine gleichmässige Anpressung des unteren Trums des Bandes 14 am entsprechenden Band 13 sorgen Rollen 18, die jeweils an einem federbelasteten Hebel 19 gelagert sind. Die übrigen Bänder 13b und 13c dienen lediglich als Auflage für die Druckprodukte B, wie dies in Fig. 2 gezeigt ist. Die oberen Trums der Bänder 13 verlaufen in der Regel horizontal und vorzugsweise etwas unterhalb der Ebene der oberen Trums der Bänder 7, 8 und 10. Die Bänder 14a sind Teleskopbänder, derart, dass die Rolle 16 in den Richtungen des Doppelpfeils 26 verschoben werden kann. Solche Teleskopbänder sind an sich gut bekannt. Die Verstellung kann an einem hier nicht gezeigten Handrad schnell und präzise erfolgen. Die Arbeitsweise der Einrichtung wird nachfolgend insbesondere anhand der Figuren 2 und 5 kurz erläutert. The second conveyor element 2 has a lower pull-out belt 13 and an upper pull-out belt 14, which run obliquely and preferably inclined at approximately 45 ° to the first conveyor crane 1. The direction of conveyance of the conveying member 2 is indicated by the arrow 25. The conveying speed of the conveying member 1 is selected such that the speed component in the conveying direction of the conveying member 1 is the same like the conveying speed of the conveying member 1. The lower pull-out belt 13 consists of six partial belts 13c arranged parallel to one another, each running at the front end around a roller 15. As can be seen from FIG. 1, these rollers 15 are offset according to the gap 11 in the conveying direction. Two belts 13a arranged in parallel next to each other work together with an upper belt 14a for capturing and pulling out printed products 3 from the shingled stream S. The belts 14a are each guided around a front deflection roller 16 and deflection rollers 17. Rollers 18, which are each mounted on a spring-loaded lever 19, ensure uniform pressing of the lower run of the belt 14 on the corresponding belt 13. The remaining bands 13b and 13c serve only as a support for the printed products B, as shown in FIG. 2. The upper runs of the belts 13 generally run horizontally and preferably somewhat below the plane of the upper runs of the belts 7, 8 and 10. The belts 14a are telescopic belts such that the roller 16 can be moved in the directions of the double arrow 26. Such telescopic tapes are well known per se. The adjustment can be made quickly and precisely on a handwheel, not shown here. The mode of operation of the device is briefly explained below, in particular with reference to FIGS. 2 and 5.
Der in Fig. 2 gezeigte Schuppenstrom S besteht aus ineinandergefaitetsn Druckprodukten A und 3, beispielsweise Zei tungen oder Zeitschriften der üblichen Art. Die Druckprodukte A und B sind seitlich gegeneinander versetzt, so dass in der Fig. 2 der untere Rand durch die Druckprodukte A und der obere Rand durch die Druckprodukte 3 allein gebildet wird. Der in Fig. 2 von links dem Förderorgan 1 übergebene Schuppenstrom S wird in Richtung des Pfeils 24 gefördert. Hierbei werden die Druckprodukte A an ihrem Rand zwischen den Pressbaiken 21 und dem Band 7 festgehalten. Dadurch werden die Druckprodukte A ohne Querbewegung in Richtung des Pfeils 24 bewegt. Die Druckprodukte B hingegen werden in der Lücke 11 von den Auszugsbändern 13 und 14 erfasst und quer zur Richtung des Pfeils 24 aus dem Schuppenstrom S herausgezogen. Damit die Druckprodukte 3 lediglich jeweils an ihrem vorstehenden Rand erfasst werden, sind die beiden Rollen 16 der 3änder 14a entsprechend in der Lücke 11 positioniert. In der Fig. 1 sind mit P1 und P2 die beiden Endpositionen der Rollen 16 angegeben. Mit der Position P1 wird ein vergleichsweise schmaler Schuppenstrom S1 und mit der Position P2 ein wesentlich breiterer Schuppenstrom S2 getrennt. Zwischen beiden Positionen P1 und P2 können die Rollen 16 stufenlos verstellt werden. Nach dem Trennen des Schuppenstrom S bilden die Druckprodukte A und 3 jeweils wieder einen Schuppenstrom, der weiteren hier nicht gezeigten Förderorganen übergeben werden kann. Die beiden Teilbänder 13a können auch durch ein einzelnes Band ersetzt sein, es hat sich jedoch gezeigt, dass bei der Verwendung von zwei Bändern die Druckprodukte 3 wesentlich besser sta bilisiert werden. Dies ist besonders dann von Bedeutung, wenn Druckprodukte mit unüblichen Formaten gefördert werden sollen. The shingled stream S shown in FIG. 2 consists of nested printing products A and 3, for example Zei lines or magazines of the usual kind. The printed products A and B are laterally offset from one another, so that in FIG. 2 the lower edge is formed by the printed products A and the upper edge by the printed products 3 alone. The scale flow S transferred from the left to the conveying element 1 in FIG. 2 is conveyed in the direction of the arrow 24. Here, the printed products A are held at their edge between the press bars 21 and the belt 7. As a result, the printed products A are moved in the direction of the arrow 24 without transverse movement. The printed products B, on the other hand, are caught in the gap 11 by the pull-out belts 13 and 14 and pulled out of the scale stream S transversely to the direction of the arrow 24. So that the printed products 3 are only grasped at their protruding edges, the two rollers 16 of the three edges 14a are positioned accordingly in the gap 11. 1, P1 and P2 indicate the two end positions of the rollers 16. Position P1 separates a comparatively narrow scale flow S1 and position P2 separates a much wider scale flow S2. The rollers 16 can be continuously adjusted between the two positions P1 and P2. After the shingled stream S has been separated, the printed products A and 3 each again form a shingled stream which can be passed on to further conveying elements which are not shown here. The two sub-bands 13a can also be replaced by a single band, but it has been shown that the printed products 3 are much better when two bands are used be accounted for. This is particularly important when printing products with unusual formats are to be conveyed.
Die erfindungsgemässe Einrichtung eignet sich auch für einen Schuppenstrom S, der gemäss Fig. 5 aus vier ineinandergefalzten Druckprodukten A1, A2, B1 und 32 besteht. Durch entsprechende Einstellung des oberen Auszugsbandes 14 kann dieser Schuppenstrom S in jeder möglichen Weise getrennt werden. Beispielweise können die Druckprodukte 32 von den übrigen Druckprodukten A1, A2 und 31 getrennt werden. Ebenfalls können in einem ersten Schritt die Druckprodukte B1 und B2 von den Druckprodukten A1 und A2 getrennt werden, wie dies in Fig. 5 gezeigt ist. Durch diese Trennung entstehen zwei Schuppenströme mit jeweils den Druckprodukten A1 und A2 bzw. B1 und B2. Mit zwei weiteren erfindungsgemässen Einrichtungen können diese Schuppenströme dann weiter aufgetrennt werden, so dass dann insgesamt vier Schuppenströme entstehen, die jeweils lediglich aus einem Druckprodukt A1, A2, B1 bzw. B2 bestehen. The device according to the invention is also suitable for a shingled stream S which, according to FIG. 5, consists of four folded printed products A1, A2, B1 and 32. By adjusting the upper pull-out belt 14 accordingly, this scale stream S can be separated in any possible way. For example, the printed products 32 can be separated from the other printed products A1, A2 and 31. Likewise, in a first step, the printed products B1 and B2 can be separated from the printed products A1 and A2, as shown in FIG. 5. This separation creates two scale streams, each with the printed products A1 and A2 or B1 and B2. These scale streams can then be separated further with two further devices according to the invention, so that a total of four scale streams then arise, each of which only consist of one printed product A1, A2, B1 or B2.
Die Kanten der Druckprodukte können voraus- oder nachlaufend und jeweils oben oder unten angeordnet sein. Der Schuppenstrom kann auch aus zwei oder mehr übereinander aber seitlich versetzt angeordneten Teiischuppenströmen bestehen. Diese Teilschuppenströme können mit der Einrichtung wie oben erläutert getrennt werden. Vor der Trennstelle können somit auf einer Förderstrecke mehrere übereinander angeordnete Teilschuppenströme gefördert werden. The edges of the printed products can be leading or trailing and can be arranged above or below. The scale flow can also consist of two or more partial scale flows arranged one above the other but laterally offset. These partial scale streams can be separated with the device as explained above. Before the separation point can thus be conveyed a plurality of partial shed streams arranged one above the other on a conveyor line.
