Abstract

The procedure for the conversion of a feed (1) of flat objects (8) into a shingle-form layered stream (2-5) entails selectively placing the objects on a supporting feed surface on a first (I) or on a second (II) depositing point and then additionally turning the objects on the first depositing point around the feed direction by 180 degrees. The objects are placed selectively on the depositing points with the held edges leading or trailing. The objects placed on the first depositing point are turned by a rotation of the laid layered stream around its own axis. Independent claims are included for a device to carry out the proposed procedure, and for a use for the procedure to produce layered stream sections or layered streams for a stack or cross-stack (6,7) for building in a stacking device.

Description

Die Erfindung liegt im Bereiche der Stückgut-Förderung und betrifft ein Verfahren und eine Vorrichtung nach den Oberbegriffen der entsprechenden, unabhängigen Patentansprüche. Verfahren und Vorrichtung dienen zur Wandlung eines Stromes von gehalten geförderten, flachen Gegenständen, insbesondere von gehalten geförderten Druckprodukten wie z.B. Zeitungen, Zeitschriften oder Broschüren in einen Schuppenstrom, wobei die relative Anordnung der Gegenstände im Schuppenstrom wählbar ist.The invention is in the field of general cargo promotion and relates to a method and a device according to the preambles of the corresponding independent Claims. Method and apparatus are used to convert a stream supported by kept, flat objects, in particular promoted held Printed products such as e.g. Newspapers, magazines or brochures in one Schuppenstrom, the relative arrangement of the objects in the scale flow is selectable.

Insbesondere in der Versandraumtechnik ist es bekannt, Druckprodukte wie Zeitungen, Zeitschriften, Broschüren oder Zwischenprodukte zu Druckprodukten hintereinander zu fördern, wobei je ein Druckprodukt von einem Greifer in einem Kantenbereich gehalten wird und die gehaltenen Kanten im wesentlichen quer zur Förderrichtung ausgerichtet sind (Strom von gehalten geförderten Produkten oder Greiferstrom) oder wobei die Druckprodukte einander überlappend meist lose auf einer Förderauflage aufliegen (Schuppenstrom). In beiden Fällen handelt es sich um dichte Förderströme, in denen die Abstände zwischen den Druckprodukten (Greiferabstände oder Schuppenabstände) wesentlich kleiner sind als die flächige Ausdehnung der Druckprodukte, so dass mit relativ geringen Fördergeschwindigkeiten grosse Förderleistungen möglich sind.Especially in mail-order technology, it is known to print products such as newspapers, Magazines, brochures or intermediates for printed products in a row each conveying a printed product from a gripper in an edge region is held and the edges held substantially transverse to the conveying direction are aligned (flow of held conveyed products or gripper stream) or wherein the printed products overlap each other mostly loose on a conveyor support rest (scale flow). Both are dense flow rates, in which the distances between the printed products (gripper distances or Scale distances) are significantly smaller than the areal extent of the printed products, so that with relatively low conveying speeds large flow rates possible are.

In Greiferströmen sind die Druckprodukte oder mindestens deren gehaltene Kanten exakt positioniert und die Gegenstände sind relativ gut zugänglich. Förderung in verschiedensten räumlichen Lagen ist möglich. Entsprechende Fördervorrichtungen sind bei konstanten Produkte- bzw. Greiferabständen relativ einfach (z.B. umlaufendes Förderorgan mit daran angeordneten Greifern). Greiferströme eignen sich insbesondere für die Förderung entlang von kompliziert verlaufenden Förderwegen und zur Bearbeitung der Druckprodukte während der Förderung.In gripper flows are the printed products or at least their held edges accurately positioned and the objects are relatively easily accessible. Promotion in various ways spatial locations is possible. Corresponding conveyors are relatively constant at constant product or gripper clearances (e.g., circumferential Conveyor organ with grippers arranged thereon). Gripper currents are particularly suitable for the promotion along complicated running routes and the Processing of printed products during promotion.

In lose aufliegend geförderten Schuppenströmen können sich die Druckprodukte leicht gegeneinander verschieben, sie können aber auch einfach wieder ausgerichtet werden und ebenso einfach können ihre Abstände auch selektiv und lokal verändert werden, solange an die Regelmässigkeit dieser Abstände nicht allzu hohe Anforderungen gestellt werden. Für Förderungen mit anderen als im wesentlichen horizontalen Produkteausrichtungen sind entsprechende Haltemittel (z.B. seitliche Klemmelemente oder Förderband-Paare) vorzusehen. Ein Nachteil von lose aufliegenden Schuppenströmen ist die beschränkte Zugänglichkeit zu den Druckprodukten und die Tatsache, dass Weiterverarbeitungs- oder Weiterfördervorrichtungen in der Regel an den zuzuführenden Schuppenstrom enge Bedingungen bezüglich der relativen Anordnung der Produkte stellen.In loosely supported shingled streams, the printed products can but they can easily be re-aligned their distances can also be selectively and locally changed as long as the regularity of these distances is not too high be put. For promotions with other than essentially horizontal Product alignments are corresponding retention means (e.g., lateral clamp members or conveyor belt pairs). A disadvantage of loose lying Scale flow is the limited accessibility to the printed products and the Fact that further processing or Weiterfördervorrichtungen in general the supplied shingled stream narrow conditions with respect to the relative arrangement of the products.

Druckprodukte sind meist rechteckig und haben vielfach eine ausgezeichnete längere Kante (Rückenkante, erster Falz oder zweiter Falz) und eine ausgezeichnete kürzere Kante (erster Falz) bzw. eine ausgezeichnete Seite (Frontseite). In Schuppenströmen sind in der Regel die längeren Kanten quer und die kürzeren Kanten parallel zur Förderrichtung ausgerichtet so dass die Druckprodukte eines Typs (ausgezeichnete Kanten und ausgezeichnete Seite gleich zueinander angeordnet) in acht verschiedenen Arten angeordnet sein können:

  • ausgezeichnete, längere Kante vorlaufend und obenliegend; Frontseite entweder oben oder unten (bzw. ausgezeichnete, kürzere Seite links oder rechts);
  • ausgezeichnete, längere Kante vorlaufend und untenliegend; Frontseite entweder oben oder unten (bzw. ausgezeichnete, kürzere Seite links oder rechts);
  • ausgezeichnete, längere Kante nachlaufend und obenliegend; Frontseite entweder oben oder unten (bzw. ausgezeichnete, kürzere Seite rechts oder links);
  • ausgezeichnete, längere Kante nachlaufend und untenliegend; Frontseite entweder oben oder unten (bzw. ausgezeichnete, kürzere Seite rechts oder links).
Printed products are usually rectangular and often have an excellent longer edge (back edge, first fold or second fold) and an excellent shorter edge (first fold) or an excellent side (front). In shingled streams, the longer edges are usually oriented transversely and the shorter edges are aligned parallel to the conveying direction, so that the printed products of one type (excellent edges and excellent side arranged in the same direction) can be arranged in eight different ways:
  • excellent, longer edge leading and overhead; Front either top or bottom (or excellent, shorter side left or right);
  • excellent, longer edge leading and lying down; Front either top or bottom (or excellent, shorter side left or right);
  • excellent, longer edge trailing and overhead; Front either top or bottom (or excellent, shorter side right or left);
  • excellent, longer edge trailing and down; Front either top or bottom (or excellent, shorter side right or left).

In Schuppenströmen, die von produzierenden Vorrichtungen (z.B. Rotation) ausgelegt werden, sind die Druckprodukte üblicherweise immer gleich angeordnet (z.B. längere Falzkante vorlaufend und obenliegend, Frontseite oben). Demgegenüber verlangen Vorrichtungen, denen Schuppenströme zugeführt werden, verschiedenste Produkteanordnungen, gegebenenfalls sogar zeitlich variierende Produkteanordnungen. So ist beispielsweise eine Stapelung nur möglich, wenn die nachlaufenden Kanten des der Stapelung zugeführten Schuppenstroms gegen den entstehenden Stapel gerichtet sind. Das heisst für einen von seitlich oben zu speisenden Stapelschacht ist ein Schuppenstrom notwendig, in dem die nachlaufenden Kanten untenliegend sind. Soll im genannten Stapelschacht ein Kreuzstapel entstehen, müssen im zuzuführenden Schuppenstrom in aufeinanderfolgenden Sektionen die ausgezeichneten, längeren Kanten alternierend vorlaufend (oben) und nachlaufend (unten) sein und die ausgezeichneten Seiten immer oben oder immer unten liegen bzw. die ausgezeichneten, kürzeren Kanten alternierend links und rechts oder alternierend rechts und links liegen. In shingled streams designed by producing devices (e.g., rotation) usually the printed products are always the same (e.g. longer folded edge leading and overhead, front side above). In contrast, require devices, to which shingled streams are fed, a wide variety Product arrangements, possibly even time-varying product arrangements. For example, a stacking is only possible if the trailing Edges of the stacking supplied scale flow against the resulting stack are directed. This means for a stackable shaft to be fed from the top a shingled stream is necessary in which the trailing edges lie down are. If a cross stack should arise in the stacking shaft mentioned, must be supplied in the Shingled stream in successive sections the excellent, longer edges alternately leading (up) and trailing (down) and the excellent sides always up or down always or the excellent, shorter edges alternately left and right or alternating right and lie left.

Den genannten, Schuppenstrom-verarbeitenden Vorrichtungen sind also gegebenenfalls Stromwandlungsvorrichtungen vorzuschalten, die eine für die nachgeschaltete Vorrichtung geeignete Anordnung der Gegenstände im zuzuführenden Schuppenstrom erstellen. Sollen vom gleichen Schuppenstrom mehrere Schuppenstromverarbeitende Vorrichtungen gespeist werden oder ändert sich die von einer Schuppenstrom-verarbeitenden Vorrichtung verlangte Anordnung von Zeit zu Zeit, muss die Stromwandlungsvorrichtung verschiedene Wandlungsmodi haben und sie muss von einem Wandlungsmodus in einen anderen schaltbar sein.The mentioned, shingled processing devices are therefore optionally Power conversion devices upstream, one for the downstream Device suitable arrangement of the objects in the supplied scale flow create. Should from the same scale flow several Schuppenstromverarbeitende Devices are fed or changed by a shingled processing Device required arrangement from time to time, must the power conversion device must have different conversion modes and it must be switchable from one conversion mode to another.

Stromwandlungs-Vorrichtungen mit zwei Wandlungsmodi sind beispielsweise beschrieben in den Publikationen EP-1157953 (oder US-2001 0048190), US-6139252, WO-02/14194 oder EP-1277685.Power conversion devices with two conversion modes are described, for example in the publications EP-1157953 (or US-2001 0048190), US-6139252, WO-02/14194 or EP-1277685.

Die Erfindung stellt sich nun die Aufgabe, ein Verfahren und eine Vorrichtung zur Stromwandlung zu schaffen, wobei die flachen Gegenstände als Greiferstrom (nacheinander, einzeln an einer Kante gehalten geförderte Gegenstände, wobei die gehaltene Kanten im wesentlichen quer zur Förderrichtung ausgerichtet ist) zugeführt werden und wobei dieser Greiferstrom wahlweise in einen Schuppenstrom mit einer von mindestens zwei, vorteilhafterweise vier wählbaren Gegenstandsanordnungen gewandelt wird, derart, dass mit dem aus der Stromwandlung anfallenden Schuppenstrom bzw. mit den aus der Stromwandlung anfallenden Schuppenstromsektionen beispielsweise in einer Stapelvorrichtung Kreuzstapel oder wahlweise in der einen oder anderen von zwei Stapelvorrichtungen mit entgegengesetzten Stapelrichtungen Stapel oder Kreuzstapel erstellt werden können. Verfahren und Vorrichtung gemäss Erfindung sollen insbesondere sehr einfach sein und ein einfaches Umschalten von einem Wandlungsmodus zu einem anderen erlauben. The invention now has the object, a method and an apparatus for To provide power conversion, wherein the flat objects as a gripper stream (successively, individually held on an edge promoted items, the held Edges is aligned substantially transverse to the conveying direction) and wherein this gripper stream optionally in a scale flow with a at least two, advantageously four selectable article arrangements is converted, such that with the resulting from the current conversion scale flow or with the resulting from the current conversion scale flow sections For example, in a stacking device cross stack or optionally in one or other of two stackers with opposite stacking directions Stack or cross stack can be created. Method and device according to In particular, the invention should be very simple and easy to switch from allow one conversion mode to another.

Diese Aufgabe wird gelöst durch das Verfahren und die Vorrichtung, wie sie in den Patenansprüchen definiert sind.This object is achieved by the method and the device, as in the Patent claims are defined.

Im erfindungsgemässen Verfahren werden die flachen Gegenstände an oberen, im wesentlichen quer zur Förderrichtung ausgerichteten Kanten gehalten durch eine erste und durch eine zweite Ablagestelle gefördert und wahlweise an der ersten oder an der zweiten Ablagestelle durch Deaktivieren (Öffnen) der Greifer losgelassen und zu einem Schuppenstrom abgelegt (zwei Wandlungsmodi). Dabei werden die an der ersten Ablagestelle abgelegten bzw. abzulegenden Gegenstände nach dem Ablegen (das heisst im Schuppenstrom), bzw. vor dem Ablegen (das heisst im Greiferstrom) um 180° gedreht, wobei der Schuppen- bzw. Greiferstrom um seine eigene Achse gedreht wird. Vor der Greifer-Deaktivierung werden die unteren, nicht gehaltenen Kanten der zugeförderten Gegenstände gegenüber den oberen gehaltenen Kanten verzögert oder beschleunigt. Für vier Wandlungsmodi ist auch diese Positionierung zur Ablage wählbar, so dass die in der Zuförderung gehaltenen Kanten im entstehenden Schuppenstrom wahlweise vorlaufend oder nachlaufend (in beiden Fällen obenliegend) sind. Zwischen der Zuförderung und der Ablage können selbstverständlich Richtungsänderungen und/oder weitere Drehungen der Produkte vorgesehen werden.In the inventive method, the flat objects at the top, in essentially oriented transversely to the conveying direction edges held by a first and promoted by a second storage location and optionally at the first or on the second storage location by disabling (opening) of the gripper and released to stored in a scale flow (two conversion modes). They will be the first Storage place deposited or to be deposited objects after depositing (ie in the shingled stream), or before depositing (ie in the gripper stream) rotated by 180 °, with the flake or gripper stream around its own axis is turned. Before the gripper deactivation, the lower, not held Edges of the conveyed objects opposite the upper edges held delayed or accelerated. For four modes of change is also this positioning selectable for storage, so that the edges held in the feed in the resulting Shingled stream optionally in advance or trailing (in both cases overhead) are. Of course, there can be between the transfer and the filing Directional changes and / or further rotations of the products are provided.

Die erfindungsgemässe Vorrichtung weist ein Zufördermittel mit Greifern und ein Wegfördermittel mit einer Förderauflage auf. Mindestens in der ersten und der zweiten Ablagestelle sind das Zufördermittel und das Wegfördermittel derart angeordnet, dass die Greifer und die Förderauflage sich gleichsinnig bewegen und die Greifer über der Förderauflage angeordnet sind. Zum Drehen der in der ersten Ablagestelle abgelegten oder abzulegenden Gegenstände ist ein Mittel zur Drehung des abgelegten Schuppenstromes (z.B. verwundenes Förderband-Paar) oder ein Mittel zum Drehen eines Greiferstromes (z.B. Zufördermittel oder Hilfsfördermittel mit Greifern, das einen verwundenen Förderweg oder senkrecht zur Förderrichtung schwenk- oder drehbare Greifer aufweist). The inventive device has a feed means with grippers and a Off-road conveyor with a conveyor pad on. At least in the first and the second storage location, the feed means and the removal means are arranged such that the grippers and the conveyor support move in the same direction and the Grippers are arranged above the conveyor support. To turn in the first storage area stored or to be deposited objects is a means for rotation of the deposited scale stream (e.g., twisted conveyor belt pair) or means for rotating a gripper stream (e.g., feed or auxiliary conveying means) Grippers, a twisted conveying path or perpendicular to the conveying direction having pivotable or rotatable grippers).

Figur 1 zeigt ein Schema des erfindungsgemässen Verfahrens zur wahlweisen Wandlung eines Zuführungsstromes 1 (Greiferstrom) zu einem von vier Schuppenströmen 2, 3, 4 und 5, die beispielsweise verwendbar sind für die wahlweise Erstellung von Stapeln 6 und 7 in einander entgegengesetzten Stapelrichtungen, wobei die erstellten Stapel wahlweise Kreuzstapel sind oder Stapel mit gleichgerichteten Gegenständen. Figure 1 shows a scheme of the inventive method for the optional conversion of a feed stream 1 (gripper stream) to one of four scale streams 2, 3, 4 and 5, for example, be used for the optional creation of stacks 6 and 7 in opposite stacking directions, the created stacks are either cross stacks or stacks with rectified objects.

Die in der Figur 1 dargestellten, flachen Gegenstände 8 sind beispielsweise gefalzte oder gebundene Druckprodukte, deren eine längere Kante F durch den Falz oder Rücken ausgezeichnet ist und deren eine Seite beispielsweise als Frontseite FS ausgezeichnet ist. Diese Druckprodukte sind im Schema mit einer Blickrichtung senkrecht zu den Förderrichtungen (Pfeile) und im wesentlichen parallel zu den ausgezeichneten Kanten F dargestellt.The flat objects 8 shown in FIG. 1 are, for example, folded or bound printed products whose one longer edge F through the fold or Back is excellent and one side, for example, as front FS awarded is. These printed products are perpendicular in the diagram with a viewing direction to the conveying directions (arrows) and substantially parallel to the excellent Edges F shown.

Im dargestellten Zuführungsstrom 1 sind die Druckprodukte 8 an den Falzkanten F gehalten und sind diese Falzkanten gegen oben gerichtet. Die Frontseiten sind beispielsweise nach hinten gerichtet. Selbstverständlich ist das erfindungsgemässe Verfahren genau gleich durchführbar, wenn die ausgezeichneten Kanten und Seiten der zugeführten Druckprodukte anders als dargestellt angeordnet sind. Aus dem dargestellten Zuführungsstrom 1 sind wahlweise die vier Schuppenströme 2, 3, 4 oder 5 erstellbar:

  • Im Schuppenstrom 2 sind die Falzkanten F vorlaufend und obenliegend, die Frontseiten FS sind gegen oben gerichtet. Dieser Schuppenstrom wird erzeugt, indem die Druckprodukte an der zweiten Ablagestelle II mit vorlaufenden Falzkanten F abgelegt werden (Wandlungsmodus A).
  • Im Schuppenstrom 3 sind die Falzkanten F nachlaufend und untenliegend, die Frontseiten FS sind gegen oben gerichtet. Dieser Schuppenstrom wird erzeugt, indem die Druckprodukte an der ersten Ablagestelle I mit nachlaufenden (gegen oben gerichteten) Falzkanten F abgelegt und dann der abgelegte Schuppenstrom um seine eigene Achse gedreht wird (Wandlungsmodus B) oder indem der Greiferstrom oder ein durch Übergabe an ein Hilfsfördermittel erstellter, weiterer Greiferstrom um seine eigene Achse gedreht und dann die Druckprodukte in der ersten Ablagestelle mit nachlaufenden (gegen unten gerichteten) Falzkanten F abgelegt werden (Wandlungsmodus B').
  • Im Schuppenstrom 4 sind die Falzkanten F nachlaufend und obenliegend, die Frontseiten FS sind gegen unten gerichtet. Dieser Schuppenstrom wird erzeugt, indem die Druckprodukte an der zweiten Ablagestelle II mit nachlaufenden Falzkanten abgelegt werden (Wandlungsmodus C).
  • Im Schuppenstrom 5 sind die Falzkanten F nachlaufend und obenliegend, die Frontseiten FS sind gegen unten gerichtet. Dieser Schuppenstrom wird erzeugt, indem die Druckprodukte an der ersten Ablagestelle I mit vorlaufenden (gegen oben gerichteten) Falzkanten F abgelegt und dann der Schuppenstrom um seine eigene Achse gedreht wird (Wandlungsmodus D) oder indem der Greiferstrom oder ein durch Übergabe erstellter, weiterer Greiferstrom um seine eigene Achse gedreht und dann die Druckprodukte in der ersten Ablagestelle I mit vorlaufenden (gegen unten gerichteten) Falzkanten F abgelegt werden (Wandlungsmodus D').
In the illustrated feed stream 1, the printed products 8 are held at the folded edges F and these folded edges are directed upwards. The front pages are directed, for example, to the rear. Of course, the method according to the invention can be performed exactly the same if the excellent edges and sides of the supplied printed products are arranged differently than shown. From the illustrated feed stream 1, the four shingled streams 2, 3, 4 or 5 can optionally be created:
  • In the scale flow 2, the folding edges F are leading and overhead, the front sides FS are directed upwards. This scale flow is generated by the printed products are stored at the second storage location II with leading fold edges F (conversion mode A).
  • In the shingled stream 3, the folding edges F are trailing and lying down, the front sides FS are directed upwards. This scale flow is generated by the printed products deposited at the first depositing point I with trailing (against the top) folding edges F and then the stored scale flow is rotated about its own axis (conversion mode B) or by the gripper stream or created by transfer to an auxiliary conveyor , Further gripper stream rotated about its own axis and then the printed products are stored in the first storage location with trailing (towards bottom) folding edges F (conversion mode B ').
  • In the scale flow 4, the folding edges F are trailing and overhead, the front sides FS are directed towards the bottom. This scale flow is generated by the printed products are stored at the second storage location II with trailing folding edges (conversion mode C).
  • In the scale flow 5, the folding edges F are trailing and overhead, the front sides FS are directed towards the bottom. This scale flow is generated by the printed products deposited at the first depositing point I with leading (against the top) folding edges F and then the scale flow is rotated about its own axis (conversion mode D) or by the gripper stream or created by transfer, another gripper stream rotated its own axis and then the printed products in the first storage location I are stored with leading (against bottom) folding edges F (conversion mode D ').

Die Schuppenströme 2 und 3 bzw. Schuppenstromsektionen mit den Produkteanordnungen wie in den Schuppenströmen 2 und 3 können für eine Stapelung beispielsweise um 90° umgelenkt und dann in einer der Förderrichtung der Stromwandlung im wesentlichen entgegengesetzten Stapelrichtung gestapelt werden, wobei Stapel 6 entstehen, in denen unabhängig davon, ob es Kreuzstapel sind oder nicht, die Frontseiten FS in Stapelrichtung hinten liegen. Die Schuppenströme 4 und 5 bzw. Schuppenstromsektionen mit den Produkteanordnungen wie in den Schuppenströmen 4 und 5 können für eine Stapelung beispielsweise um 90° umgelenkt und dann in einer mit der Förderrichtung der Stromwandlung im wesentlichen gleichgerichteten Stapelrichtung gestapelt werden, wobei Stapel 7 entstehen, in denen unabhängig davon, ob es Kreuzstapel sind oder nicht, die Frontseiten FS in Stapelrichtung hinten liegen. Die Stapel 6 und 7 sind also in Stapelrichtung gesehen bezüglich Orientierung der Druckprodukte gleich.The scale flows 2 and 3 or scale flow sections with the product arrangements as in the shingled streams 2 and 3, for example, for stacking deflected by 90 ° and then in one of the conveying direction of the current conversion stacked in substantially opposite stacking direction, wherein stack 6 arise in which, regardless of whether they are cross stacks or not, the fronts FS lie in stacking direction behind. The scale flows 4 and 5 or scale flow sections with the product arrangements as in the scale flows 4 and 5 can be deflected for example by 90 ° for a stacking and then in a with the conveying direction of the current conversion substantially rectified stacking direction stacked, resulting in stacks 7, in which regardless of whether it's cross stacks or not, the fronts FS lie in the stacking direction behind. The stack 6 and 7 are thus seen in the stacking direction with respect to the Same as printed products.

Für die Herstellung von Kreuzstapeln 6 ist die Stromwandlungsvorrichtung periodisch umzuschalten von Wandlungsmodus A auf Wandlungsmodus B bzw. B' und umgekehrt, das heisst, es wird zwischen Ablegen an der Ablagestelle I und an der Ablagestelle II abgewechselt, wobei an den Ablagestellen nichts verändert wird oder die Ablagestellen nicht einstellbar ausgestaltet sein können. Dasselbe gilt für Kreuzstapel 7 (Schaltung von Wandlungsmodus C auf Wandlungsmodus D bzw. D' oder umgekehrt). Wird von einer Herstellung von Stapeln 6 auf Stapel 7 gewechselt (Schaltung von Wandlungsmodi A und B bzw. B' auf Wandlungsmodi C und D bzw. D' oder umgekehrt), werden die Ablagestellen I und II umgeschaltet, das heisst, von einer Ablage mit vorlaufenden, gehaltenen Kanten auf eine Ablage mit nachlaufenden, gehaltenen Kanten oder umgekehrt. Die Schaltung zwischen verschiedenen Wandlungsmodi ist also offensichtlich sehr einfach.For the production of cross stacks 6, the power conversion device is periodic switch from conversion mode A to conversion mode B or B 'and vice versa, that is, it is between storage at the deposit I and at the Depot II alternated, where at the filing is not changed or the filing points can not be configured adjustable. The same applies to cross stacks 7 (switching from conversion mode C to conversion mode D or D 'or vice versa). Is changed from a production of stacks 6 on stack 7 (Switching of conversion modes A and B or B 'to conversion modes C and D or D 'or vice versa), the filing points I and II are switched, that is, from a shelf with leading, held edges on a shelf with trailing, held edges or vice versa. The circuit between different Conversion modes is obviously very simple.

Aus der Figur 1 ist auch ersichtlich, dass durch Förderrichtungsänderungen oder weitere Drehungen zwischen Zuführung und Ablage die Schuppenströme 2 bis 5 anders orientiert sein können, als dies in der Figur 1 dargestellt und in den obigen Abschnitten beschrieben ist. Dies verändert aber die einfache Schaltbarkeit zwischen zwei oder vier verschiedenen Wandlungsmodi nicht.From Figure 1 it is also seen that by conveying direction changes or further rotations between feed and tray the scale flows 2 to 5 differently may be oriented as shown in Figure 1 and in the sections above is described. But this changes the simple switchability between two or four different conversion modes not.

Figuren 2 und 3 zeigen schematisch eine vorteilhafte Ausgestaltung einer Ablagestelle. Es kann sich dabei um die erste Ablagestelle I handeln und zwar unabhängig davon, ob vor oder nach der Drehung abgelegt wird (Wandlungsmodi B, D, B', D'), oder um die zweite Ablagestelle II (Wandlungsmodi A und C). In der Figur 2 ist die Ablagestelle eingestellt für eine Ablage mit nachlaufenden, gehaltenen Kanten, in der Figur 3 für eine Ablage mit vorlaufenden, gehaltenen Kanten. Sehr schematisch dargestellt sind ein Zufördermittel 10 oder Hilfsfördermittel 10' mit Greifern 11 (bzw. 11') und ein Wegfördermittel 12 mit einer Förderauflage 13, wobei die Greifer 11 und die Förderauflage 13 gleichgerichtet angetrieben werden und die Greifer 11 sich von oben gegen die Förderauflage 13 bewegen. In der Ablagestelle sind Deaktivierungsmittel 15 angeordnet, mit denen die Greifer 11 gegebenenfalls selektiv deaktiviert, das heisst in eine den gehaltenen Gegenstand loslassende Konfiguration gebracht, beispielsweise geöffnet werden. Figures 2 and 3 show schematically an advantageous embodiment of a storage location. It may be the first storage location I, regardless of whether before or after the rotation is stored (conversion modes B, D, B ', D'), or the second storage location II (conversion modes A and C). In FIG. 2, the deposit location is set for a deposit with trailing, held edges, in FIG. 3 for a deposit with leading, held edges. Very schematically illustrated are a feed means 10 or auxiliary conveyor 10 'with grippers 11 (or 11') and a removal conveyor 12 with a conveyor support 13, wherein the gripper 11 and the conveyor support 13 are driven rectified and the gripper 11 from above against the conveyor support 13 move. Deactivation means 15, with which the grippers 11 are optionally selectively deactivated, that is to say brought into a configuration releasing the held object, for example opened, are arranged in the depositing station.

Die Geschwindigkeit der Greifer 11 und der Förderauflage 13 durch die Ablagestellen sind vorteilhafterweise gleich, die Förderauflage 13 kann sich auch etwas schneller bewegen. Wenn die flachen Gegenstände oder Druckprodukte 8 in diesem Falle ungehindert zugeführt werden, werden die ungehaltenen Kanten, sobald sie mit der Förderauflage 13 in Berührung kommen, gegenüber den gehaltenen Kanten beschleunigt, so dass die Gegenstände in eine schiefe Lage kommen und mit nachlaufenden, gehaltenen Kanten abgelegt werden. Wenn vor der Stelle, an der die Greifer geöffnet werden, ein Hindernis 14 zwischen Förderauflage 13 und Greifern 11 in den Greiferstrom eingeschoben wird, müssen die ungehaltenen Kanten der Gegenstände 8 über dieses Hindernis 14 gezogen werden, wodurch sie gegenüber den gehaltenen Kanten verzögert werden, so dass die Gegenstände mit vorlaufenden, gehaltenen Kanten abgelegt werden.The speed of the gripper 11 and the conveyor support 13 through the storage locations are advantageously the same, the conveyor support 13 may be something move faster. If the flat objects or printed products 8 in this Traps are fed unhindered, the disgusted edges, as soon as they are with the conveyor support 13 come into contact, accelerated with respect to the held edges, so that the objects come in a crooked position and with trailing, held edges are stored. If in front of the point where the gripper be opened, an obstacle 14 between conveyor support 13 and grippers 11 in the Gripper stream is inserted, the ungated edges of the objects must 8 are pulled over this obstacle 14, whereby they held against the obstacle Edges are delayed, so that the objects with leading, held Edges are stored.

Für ein Umschalten der in den Figuren 2 und 3 dargestellten Ablagestelle von einer Ablage mit nachlaufenden, gehaltenen Kanten auf eine Ablage mit vorlaufenden, gehaltenen Kanten ist also lediglich das Hindernis 14 in den Greiferstrom einzubringen. Für eine umgekehrte Schaltung ist das Hindernis 14 aus dem Greiferstrom zu entfernen.For switching the storage location shown in Figures 2 and 3 of a Tray with trailing, held edges on a shelf with leading, held Edges is therefore only the obstacle 14 to introduce into the gripper stream. For a reverse circuit, the obstacle 14 is to be removed from the gripper stream.

Figur 4 zeigt in einer sehr schematischen Art eine beispielhafte Ausführungsform einer erfindungsgemässen Stromwandlungsvorrichtung, mit der ein Zuführungsstrom 1, der durch ein Zufördermittel 10 mit Greifern 11 zugefördert wird, in einen Schuppenstrom mit wählbarer Gegenstandsanordnung gewandelt wird, wobei der Schuppenstrom auf einer Förderauflage 13 weggefördert wird. Es handelt sich um eine Ausführungsform mit den Wandlungsmodi A, B, C und D. Dargestellt sind die Modi C in Ablagestelle II und D in Ablagestelle I. Das Wegfördermittel 12 weist zwischen der ersten Ablagestelle I und der zweiten Ablagestelle II einen Drehbereich 21 auf, in dem der in der ersten Ablagestelle I abgelegte Schuppenstrom um 180° um seine eigene Achse gedreht wird. Der Drehbereich 21 ist beispielsweise in an sich bekannter Art durch ein um 180° verwundenes Förderband-Paar (nicht dargestellt) realisiert, wobei die Gegenstände im wesentlichen von dem vor der Verwindung unteren Band auf das nach der Verwindung untere Band laufen. FIG. 4 shows, in a very schematic manner, an exemplary embodiment of a power conversion device according to the invention, with which a feed stream 1, which is conveyed by feed means 10 with grippers 11, is converted into a shingled stream with selectable object arrangement, wherein the shingled stream is conveyed away on a conveying support 13 , It is an embodiment with the conversion modes A, B, C and D. Shown are the modes C in storage II and D in storage area I. The Wegfördermittel 12 has between the first storage location I and the second storage location II a rotation area 21, in which the imbricated flow deposited in the first depositing point I is rotated by 180 ° about its own axis. The rotating portion 21 is realized, for example, in a manner known per se by a conveyor belt pair wound by 180 ° (not shown), the articles essentially running from the lower belt before the twisting to the lower belt after the twisting.

Die beiden Ablagestellen I und II sind für vier Wandlungsmodi ausgestaltet und umschaltbar, wie dies in den Figuren 2 und 3 dargestellt ist. Das Zufördermittel 10 weist ein umlaufendes Förderorgan (nur Teil davon dargestellt) und daran angeordnete Greifer 11 auf. Das Förderorgan ist derart geführt, dass es sich an den beiden Ablagestellen I und II gegen die Förderauflage 13 des Wegfördermittels 12 absenkt.The two storage locations I and II are designed for four conversion modes and switchable, as shown in Figures 2 and 3. The feed means 10 has a revolving conveyor (only part of it shown) and arranged thereon Gripper 11 on. The funding body is managed in such a way that it is at the two filing points I and II lowers against the conveyor support 13 of the removal means 12.

Für die in der Figur 4 dargestellte Ausführungsform der erfindungsgemässen Stromwandlungsvorrichtung ist es vorteilhaft, wenn, wie dargestellt, die erste Ablagestelle I in Förderrichtung des Wegfördermittels 12 vor der zweiten Ablagestelle II angeordnet ist. Andernfalls müssten die gedrehten Gegenstände in einer gegebenenfalls schaltbaren Schuppenstrom-Zusammenführung auf die Förderauflage 13 des Wegfördermittels übergeben werden, was die Vorrichtung bedeutend komplizierter machen würde.For the embodiment of the inventive power conversion device shown in FIG it is advantageous if, as shown, the first storage location I arranged in the conveying direction of the removal means 12 in front of the second storage location II is. Otherwise, the rotated items would have to be in one switchable scale flow merging on the conveyor support 13 of the removal means which make the device significantly more complicated would.

Figuren 5 bis 7 zeigen drei weitere, beispielhafte Ausführungsformen der erfindungsgemässen Stromwandlungsvorrichtung. Es handelt sich um Ausführungsformen mit den Wandlungsmodi A, B', C und D'. Dargestellt sind in den Figuren 5 und 7 die Modi A (II) und B' (I), in der Figur 6 die Modi C (II) und D' (I). Diese Vorrichtungen weisen ein Hilfsfördermittel 10' mit weiteren Greifern 11' auf, die die Gegenstände an einer Übergabestelle 22 vom Zufördermittel 10 an den den gehaltenen Kanten gegenüberliegenden Kanten ergreifend als weiteren Greiferstrom übernehmen. Der so erstellte, weitere Greiferstrom (Figuren 5 und 6) oder der zugeführte Greiferstrom (Figur 7) wird in einem Drehbereich 21 um 180° um seine eigene Achse gedreht und in der ersten Ablagestelle I abgelegt, während der andere Greiferstrom an der Ablagestelle II abgelegt wird. Figures 5 to 7 show three further exemplary embodiments of the inventive power conversion device. These are embodiments with the conversion modes A, B ', C and D'. Shown in FIGS. 5 and 7 are the modes A (II) and B '(I), in FIG. 6 the modes C (II) and D' (I). These devices have an auxiliary conveyor 10 'with further grippers 11', which take the objects at a transfer point 22 from the feed means 10 at the edges opposite the held edges moving as another gripper stream. The thus created, further gripper stream (Figures 5 and 6) or the supplied gripper stream (Figure 7) is rotated in a rotation range 21 by 180 ° about its own axis and stored in the first storage location I, while the other gripper stream stored at the storage location II becomes.

Die Vorrichtung gemäss Figur 5 weist ein separates Hilfsfördermittel 10' auf, das ein umlaufendes Förderorgan (nur Teil davon dargestellt) mit Greifern 11' aufweist, während in der Vorrichtung gemäss Figur 6 das Zufördermittel 10 derart geschlauft geführt ist, dass ein Bereich davon, der für die Zuförderung nicht gebraucht wird, die Funktion des Hilfsfördermittels 10' übernehmen kann. Das Hilfsfördermittel 10' gemäss Figur 7 ist entweder ein separates Fördermittel oder ein Bereich des Zufördermittels 10.The device according to FIG. 5 has a separate auxiliary conveying means 10 ', which has a revolving conveyor (only part of it shown) with grippers 11 ', while in the apparatus according to Figure 6, the feed means 10 geschlauft such that an area of it which is not needed for the promotion, the Function of the auxiliary conveyor 10 'can take over. The auxiliary conveyor 10 'according to Figure 7 is either a separate conveyor or a portion of the conveyor 10th

Die Drehung des vom Zufördermittel 10 oder vom Hilfsfördermittel 10' geförderten, weiteren Greiferstromes vor der ersten Ablagestelle I (Drehbereich 21) wird in an sich bekannter Weise realisiert durch Verwinden des Förderorgans um 180° oder durch Verschwenken oder Drehen der Greifer 11' senkrecht zur Förderrichtung um 180°.The rotation of the conveyed by the feed means 10 or the auxiliary conveyor 10 ', another gripper stream in front of the first storage location I (rotation range 21) is in known manner realized by twisting the conveyor member by 180 ° or by pivoting or turning the gripper 11 'perpendicular to the conveying direction 180 °.

Gemäss der in der Figur 7 dargestellten Ausführungsform werden die an der ersten Ablagestelle I abzulegenden Gegenstände ohne Übergabe im Greiferstrom gedreht, während die an der zweiten Ablagestelle II abzulegenden Gegenstände an die Greifer 11' des Hilfsfördermittels 10' übergeben werden. Beide Greiferströme werden dann in eine der Zuführungsrichtung entgegengesetzte Wegförderrichtung, die auch die Förderrichtung des Wegfördermittels 12 ist, umgelenkt und erst dann abgelegt. According to the embodiment shown in FIG Depositing point I deposited objects without transfer in the gripper stream, while to be deposited at the second storage location II objects to the gripper 11 'of the auxiliary conveyor 10' are passed. Both gripper streams are then in a feed direction opposite Wegförderrichtung, including the The conveying direction of the removal means 12 is deflected and only then deposited.

Aus den Figuren 5 bis 7 ist ersichtlich, dass für diese Ausführungsformen der erfindungsgemässen Stromwandlungsvorrichtung die erste Ablagestelle I in Förderrichtung der Förderauflage 13 auch weiter stromabwärts angeordnet sein kann als die zweite Ablagestelle II, ohne dass dies die Vorrichtung wesentlich komplizierter macht.From FIGS. 5 to 7 it can be seen that for these embodiments the inventive Power conversion device, the first storage location I in the conveying direction the conveyor support 13 can also be arranged further downstream than the second storage location II, without this significantly complicates the device power.
