Definitions
- the invention relates to a method and a device for stabilizing and positioning of flat objects, in particular printed products, during transport.
- Flexible articles such as printed products, tend to bend and even fan out during transport in a suspended position, especially at higher conveying speeds due to air resistance.
- the known device is relatively inflexible, as with a change in the product length and the trajectory of the guide elements must be adjusted.
- the invention has for its object to further develop the known method and the known device such that products of different formats can be stabilized without major structural adjustments.
- At least one leading and one trailing limiting element are present, which are moved into the delivery flow in a stabilizing section of the conveying path.
- delivery flow refers to that spatial region which is swept by the products as they move in the conveying direction.
- the stabilizing section is that section of the conveying path in which at least one of the leading and trailing boundary elements is located in the flow.
- the leading or trailing limiting element limits the position of the non-held second edge in or against the conveying direction. It is not necessary, but possible, that the second edge is touched by one or both limiting elements and thereby guided.
- a plurality of leading and trailing boundary elements are moved alternately one behind the other along a closed orbit which preferably extends at least partially parallel to the stabilization section. Preferably, they are only in the area of the second edge of the product to be adjacent. Such an arrangement is particularly easy to implement.
- the further limiting element is preferably likewise moved along a closed circulation path, for example by being attached to a wheel arranged at the beginning of the stabilization section. Its movement is preferably synchronized with the movement of the leading and trailing limiters and the conveyed products.
- leading and trailing boundary elements can also be part of a device to which the subsidized products are to be transferred.
- the leading and trailing boundary elements may be formed by the jaws of grippers of a gripper conveyor.
- the further limiting element also serves here to introduce the second edge in a well-defined manner in the receptacle, which is formed in this case by the gripper.
- FIG. 1 shows a stabilizing device 10 according to the invention in connection with a conveying device 12 and a pressing device 22.
- Fig. 2a-d show various snapshots of the device in the beginning of the stabilization section.
- Fig. 3 shows a view of the stabilizing device in the conveying direction in the initial region of the stabilizing section along the line AA in Fig. 1
- Fig. 4 shows a view of the stabilizing device in the conveying direction along the line BB in Fig. 1 ie immediately before the action of the pressing device 22 on the positioned products 16.
- the printed products 16 are conveyed by the conveyor 12 in a suspended position along a straight conveyor section 11 in a horizontal conveying direction F.
- a first edge 18 of the product 16 is gripped by a respective gripper 14 of the conveyor 12.
- the edge 18 opposite this second edge 20 is deflected by the air resistance from its ideal position, especially at higher conveying speeds, in which it is located substantially below the first edge 18.
- the stabilizing device 10 serves to stabilize the lower edges 20 of printed products 16 or to limit their position, in particular to bring them back into this ideal position.
- the lower edge 20 can be provided by a pressing device 22 with a supplementary product 38, for example an adhesive tape section.
- the pressing device 22 is in detail in the not pre-published CH Patent Application No. 2003 1602/03 described, which is referred to here. Instead of the pressing device 22, further processing stations, eg gripper conveyor, cutting, labeling can be present.
- the stabilization device 10 comprises a plurality of leading boundary elements 24 and trailing boundary elements 26, which are arranged alternately behind one another and are moved along a common circulation path U.
- the orbit U in the present case has two elongated straight sections U2, U4 which run parallel to the conveying direction F in the stabilizing section S and are connected by semicircular end sections U1, U3.
- the upstream end portion U1 marks the initial region S1 of the stabilizing portion S.
- the stabilizing device 10 comprises two further limiting elements 28 which are formed by two cams 31 of a cam wheel 30 arranged in the initial region S1.
- a leading delimiting element 24 and a subsequent trailing limiting element 26 form a receptacle 27 for the lower edge 20 of a printed product 16.
- the cams 31 and further delimiting elements 28 serve to separate the intermediate region 29 between two receptacles 27 at least in the initial region S1 of the stabilizing section S cover so that the lower edge 20 of the printed product 16, regardless of their current position only in a receptacle 27, but can not get into the intermediate region 29.
- the boundary elements 24, 26 are wedge-shaped in side view and have flat boundary surfaces 44 and 42, which are at least in the course of the stabilization section S parallel to the desired position of the products 16, that is vertically oriented here.
- Another form of the limiting elements 24, 26 is possible.
- the leading or trailing boundary elements 24, 26 are each at regular intervals d1, d2 (see Fig. 2a ) are arranged on a conveying member 46 through which the orbit is substantially defined.
- the front and trailing boundary elements 24, 26 In the semicircular end portion U1 at the beginning of the stabilization section S approach the front and trailing boundary elements 24, 26 from below the flow 54. They sting from below between each two successive products 16, to finally be oriented in the straight portion U1 with their boundary surfaces 42, 44 parallel to the products 16.
- the further limiting elements 28 are moved during the movement of the cam wheel 30 along a circular path of movement K, which coincides over an angle of 180 ° with the end portion U1 of the movement path U of the limiting elements 24, 26 or parallel thereto.
- the cams 31 each have the approximate shape of a circle segment with two substantially radially oriented first and second flanks 31a, 31b with an opening angle ⁇ of about 90 ° (see Fig. 2b ).
- a lateral surface 31c which, as here, has the shape of a circular arc section
- the outer termination can also be shaped in other ways. Furthermore, only one or more than two cams may be present.
- the cam wheel 30 and the conveying member 46 for the leading and trailing limiting elements 24, 26 are driven via a drive device 40 which is coupled via a drive element 41 with the pressing device 22.
- the drive element 41, the conveying member 46 and the cam wheel 30 are arranged on a common shaft 48 and are therefore moved synchronously.
- a preferred embodiment is shown, in which mirror-symmetrical to a vertical, running in the conveying direction plane two rounds with limiting elements 24, 26, 28 are present. Between these grip the holding elements 32 of the pressing device 22 and approximately centrally on the products 16, as will be explained below.
- Fig. 2a-d are the distance d1 between a respective front and a trailing limiting element 24, 26 and the distance d2 between each a trailing and a leading limiting element 26, 24 and the angle ⁇ between the flanks 31a, 31b of the cam wheel 30 and the rotational speeds of the conveying member 46 and the cam wheel 30 are adapted to one another in such a way that the intermediate region 29 located between two receptacles 27 in the initial region S1 is covered by the cam 31 when a product 16 approaches the stabilizing portion S (see FIG Fig. 2a and 2b ). Thus, the product 16 entering the stabilization section S can not get into this intermediate region 29.
- a receptacle 27 is brought from below to the product 16 ( Fig. 2c ).
- the second flank 31b of the cam 31 protrudes counter to the conveying or rotation direction in front of the boundary surface 44 of the leading limiting element 24.
- Fig. 2d shows the state in which the further limiting element 28, ie the cam 31, is replaced by the leading delimiting element 24.
- the rearwardly directed second edge 31b of the cam 31 aligned transversely to the conveying direction F, the rearwardly directed second edge 31b of the cam 31 with the also rearwardly directed boundary surface 44 of the leading limiting element 24.
- the position of the newly occurred product 16 in the conveying direction F is thus limited by the leading delimiting element 24.
- the cam wheel 30 has the advantage that it prevents the penetration of product parts into the intermediate regions 29 in the critical initial region S1 of the stabilizing section S in a simple manner, but only rotates and does not have to be moved over the entire stabilizing path S. It is easy to manufacture and to drive with little effort.
- the products 16 are accompanied by the stabilizing section S by the leading and trailing limiting elements 24, 26 at the same speed, so that the position of the lower edge 20 is well defined. A touch can, but does not have to take place.
- the stabilizing device 10 operates according to a pressing device 22 CH Patent Application No. 2003 1602/03 together.
- This has arranged on a wheel holding elements 32, each comprising a pivotable support member 34 and a movable bending element 36.
- the holding elements 32 are brought from below to the products 16 and engage, transversely to the conveying direction laterally offset from the limiting elements 24, 26, at the lower edge 20 at.
- the trailing limiters 26 may be provided with a pivoting mechanism so that the lower edge 20 may be fixed between the limiters 24, 26. This is in Fig. 5
- the trailing limiters 26 are biased in a forwardly inclined position (shown by solid lines). By means of a slide control 50 they are tilted in a vertical position (broken lines).
- the stabilizing device may also comprise a gripper conveyor whose grippers are formed by two respective delimiting elements 24, 26. This fixed product layer can be followed by exact processing operations.
- Fig. 6 shows a further example of a stabilizing device according to the invention 10.
- This serves to a reliable transfer of products 16 from a conveyor 12, in which they are held by gripper 14 and conveyed in a hanging position in the conveying direction F, to another gripper conveyor 56.
- the stabilization device 10 includes as in the example Fig. 1-5 leading and trailing boundary elements 24, 26 which limit the position of the lower product edge 20 in or against the conveying direction F in the course of the stabilization section S.
- the boundary elements 24, 26 are moved as in the above example by a circulating conveyor member 46 along a closed orbit U. As in the above example, this is composed of straight sections U2, U4 and circular sections U1, U3 oriented in the conveying direction.
- the trailing boundary elements 26 are wedge-shaped and oriented radially outward.
- the leading boundary elements 24 are also wedge-shaped. They are pivotable about a transverse to their direction of movement or to the conveying direction F pivot axis 60 of a in the sections U4 and U1 tangentially or secantially to the orbit U oriented position in the course of section U2 radially outwardly oriented position.
- the pivoting serves to drive in the initial region S1 of the stabilizing section S first under the edge 20 to be narrowed and, during the folding up of the stabilizing section S, to block any product parts bent forwards in the conveying direction F.
- further limiting elements 28 act on the products 16 in front of and at the beginning region S1.
- a forwardly directed guide surface 31a is preferably oriented approximately parallel to the product 16. It is also possible that the further limiting element 28 at a distance from the ideal position of the product in the Injecting flow 54 and the product catches up to the beginning of S1 and thus brings into the ideal position.
- the further limiting element 28 is functionally replaced by a trailing limiting element 26.
- the forwardly delimiting boundary surface 42 aligns with the guide surface 31a.
- the further limiting element 28 is removed from the delivery stream 54. This is preferably done by means of a mechanical link control with a control link 50.
- the further limiting element 28 is held in a tangential to its orbit U 'extending position and is brought by the control link 50 in a position in which it is oriented radially to the orbit. The influence of the control link 50 ends in the initial region S1.
- open grippers 58 approach the products 16. These grip the products 16 in the area of the lower edge 20 which is now bounded. The grippers 14 of the conveyor 12 are then opened and the products are transferred to the gripper conveyor 56.
- the limiting elements 24, 26, 28 and the gripper conveyor 56 are preferably driven synchronously, in particular with the same drive device (not shown).
- the further limiting element 28 according to Fig. 6 can also instead of the cam wheel 30 in the arrangement according to Fig. 1 be used and vice versa.
- leading and trailing boundary elements 24, 26 with a further limiting element 28 has the advantage that the leading and trailing boundary elements 24, 26 can be made relatively simple and compact.
- the leading and trailing limiting elements 24, 26 themselves do not have to travel long distances in order to capture individual product parts and bring them into the ideal position.

Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Stabilisierung und Positionierung von flächigen Gegenständen, insbesondere Druckereiprodukten, während des Transports.The invention relates to a method and a device for stabilizing and positioning of flat objects, in particular printed products, during transport.
Flexible Gegenstände, wie zum Beispiel Druckereiprodukte, tendieren dazu, sich beim Transport in hängender Lage insbesondere bei höheren Fördergeschwindigkeiten aufgrund des Luftwiderstands zu verbiegen und unter Umständen sogar aufzufächern. Um ein unkontrolliertes Verbiegen oder Auffächern des Produkts zu verhindern, ist es bekannt, die Produkte teilweise durch eine Auflage abzustützen, auf der die nicht gehaltene Kante entlang gleitet.Flexible articles, such as printed products, tend to bend and even fan out during transport in a suspended position, especially at higher conveying speeds due to air resistance. In order to prevent uncontrolled bending or fanning of the product, it is known to partially support the products by a support on which slides the non-held edge along.
Aus der
Die bekannte Vorrichtung ist verhältnismässig unflexibel, da bei einer Veränderung der Produktlänge auch die Bewegungsbahn der Führungselemente angepasst werden muss.The known device is relatively inflexible, as with a change in the product length and the trajectory of the guide elements must be adjusted.
Der Erfindung liegt die Aufgabe zugrunde, das bekannte Verfahren und die bekannte Vorrichtung derart weiterzuentwickeln, dass Produkte unterschiedlichen Formats ohne grosse konstruktive Anpassungen stabilisiert werden können.The invention has for its object to further develop the known method and the known device such that products of different formats can be stabilized without major structural adjustments.
Die Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen von Anspruch 1 und durch eine Vorrichtung mit den Merkmalen von Anspruch 8. Vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Ansprüchen, der Beschreibung und den Zeichnungen.The object is achieved by a method having the features of
Erfindungsgemäss sind wenigstens ein vorlaufendes und ein nachlaufendes Begrenzungselement vorhanden, die in einem Stabilisierungsabschnitt der Förderstrecke in den Förderstrom hineinbewegt werden. Unter Förderstrom wird derjenige Raumbereich verstanden, der von den Produkten bei ihrer Bewegung in Förderrichtung überstrichen wird. Der Stabilisierungsabschnitt ist derjenige Abschnitt der Förderstrecke, in dem sich wenigstens eines der vor- und nachlaufenden Begrenzungselemente im Förderstrom befindet. Das vorlaufende bzw. nachlaufende Begrenzungselement begrenzt die Position der nicht gehaltenen zweiten Kante in bzw. entgegen der Förderrichtung. Dabei ist es nicht notwendig, aber möglich, dass die zweite Kante von einem oder beiden Begrenzungselementen berührt und dadurch geführt wird. Um sicherzustellen, dass die zweite Kante nur in die Aufnahme zwischen dem vorlaufenden bzw. nachlaufenden Begrenzungselement, nicht aber in den Zwischenbereich zwischen zwei Aufnahmen gelangt, ist erfindungsgemäss ein weiteres Begrenzungselement vorhanden. Dieses wird vor oder im Anfangsbereich des Stabilisierungsabschnitts in den Förderstrom hineinbewegt.According to the invention, at least one leading and one trailing limiting element are present, which are moved into the delivery flow in a stabilizing section of the conveying path. The term "delivery flow" refers to that spatial region which is swept by the products as they move in the conveying direction. The stabilizing section is that section of the conveying path in which at least one of the leading and trailing boundary elements is located in the flow. The leading or trailing limiting element limits the position of the non-held second edge in or against the conveying direction. It is not necessary, but possible, that the second edge is touched by one or both limiting elements and thereby guided. To ensure that the second edge only passes into the receptacle between the leading and trailing boundary element, but not in the intermediate area between two shots, is According to the invention a further limiting element available. This is moved into the flow before or in the initial region of the stabilization section.
Vorzugsweise werden eine Mehrzahl von vor- und nachlaufenden Begrenzungselementen abwechselnd hintereinander entlang einer geschlossenen Umlaufbahn bewegt, die vorzugsweise wenigstens teilweise parallel zum Stabilisierungsabschnitt verläuft. Bevorzugt befinden sie sich nur im Bereich der einzugrenzenden zweiten Kante des Produkts. Eine derartige Anordnung lässt sich besonders leicht realisieren.Preferably, a plurality of leading and trailing boundary elements are moved alternately one behind the other along a closed orbit which preferably extends at least partially parallel to the stabilization section. Preferably, they are only in the area of the second edge of the product to be adjacent. Such an arrangement is particularly easy to implement.
Das weitere Begrenzungselement wird vorzugsweise ebenfalls entlang einer geschlossenen Umlaufbahn bewegt, beispielsweise indem es an einem am Beginn des Stabilisierungsabschnitts angeordneten Rad angebracht ist. Seine Bewegung ist vorzugsweise mit der Bewegung der vorund nachlaufenden Begrenzungselemente und der geförderten Produkte synchronisiert.The further limiting element is preferably likewise moved along a closed circulation path, for example by being attached to a wheel arranged at the beginning of the stabilization section. Its movement is preferably synchronized with the movement of the leading and trailing limiters and the conveyed products.
Die vor- und nachlaufenden Begrenzungselemente können auch Teil einer Vorrichtung sein, an die die geförderten Produkte übergeben werden sollen. Beispielsweise können die vor- und nachlaufenden Begrenzungselemente durch die Backen von Greifern eines Greiferförderers gebildet sein. Das weitere Begrenzungselement dient auch hier dazu, die zweite Kante gut definiert in die Aufnahme einzuführen, die in diesem Fall durch den Greifer gebildet ist.The leading and trailing boundary elements can also be part of a device to which the subsidized products are to be transferred. For example, the leading and trailing boundary elements may be formed by the jaws of grippers of a gripper conveyor. The further limiting element also serves here to introduce the second edge in a well-defined manner in the receptacle, which is formed in this case by the gripper.

Die Druckereiprodukte 16 werden von der Fördereinrichtung 12 in hängender Lage entlang einer hier geraden Förderstrecke 11 in einer hier horizontalen Förderrichtung F gefördert. Eine erste Kante 18 des Produkts 16 ist mit jeweils einem Greifer 14 der Fördereinrichtung 12 gegriffen. Die dieser Kante 18 gegenüberliegende zweite Kante 20 wird insbesondere bei höheren Fördergeschwindigkeiten durch den Luftwiderstand aus ihrer Idealposition ausgelenkt, in der sie sich im wesentlichen unterhalb der ersten Kante 18 befindet. Die Stabilisierungsvorrichtung 10 dient dazu, die unteren Kanten 20 von Druckereiprodukten 16 zu stabilisieren bzw. deren Position einzugrenzen, insbesondere um sie wieder in diese Idealposition zu bringen. Damit wird in diesem Fall ermöglicht, dass die untere Kante 20 durch eine Andrückvorrichtung 22 mit einem Ergänzungsprodukt 38, z.B. einem Klebebandabschnitt, versehen werden kann. Die Andrückvorrichtung 22 ist im Einzelnen in der nicht vorveröffentlichten
Die Stabilisierungsvorrichtung 10 umfasst eine Mehrzahl von vorlaufenden Begrenzungselementen 24 und nachlaufenden Begrenzungselementen 26, die abwechselnd hintereinander angeordnet sind und entlang einer gemeinsamen Umlaufbahn U bewegt werden. In einem Stabilisierungsabschnitt S der Förderstrecke der Fördereinrichtung 12 werden die Begrenzungselemente 24, 26 in den Förderstrom 54 der Produkte 16 hineingeführt. Die Umlaufbahn U hat vorliegend zwei längliche gerade Abschnitte U2, U4, die im Stabilisierungsabschnitt S parallel zur Förderrichtung F verlaufen und durch halbkreisförmige Endabschnitte U1, U3 verbunden sind. Der stromaufwärts liegende Endabschnitt U1 markiert den Anfangsbereich S1 des Stabilisierungsabschnitts S. Die Stabilisierungsvorrichtung 10 umfasst zwei weitere Begrenzungselemente 28, die durch zwei Nocken 31 eines im Anfangsbereich S1 angeordneten Nockenrads 30 gebildet sind.The
Jeweils ein vorlaufendes Begrenzungselement 24 und ein diesem nachfolgendes nachlaufendes Begrenzungselement 26 bilden eine Aufnahme 27 für die untere Kante 20 eines Druckereiprodukts 16. Die Nocken 31 bzw. weiteren Begrenzungselemente 28 dienen dazu, den Zwischenbereich 29 zwischen jeweils zwei Aufnahmen 27 zumindest im Anfangsbereich S1 des Stabilisierungsabschnitts S derart abzudecken, dass die untere Kante 20 des Druckereiprodukts 16 ungeachtet ihrer momentanen Lage nur in eine Aufnahme 27, nicht aber in den Zwischenbereich 29 geraten kann.In each case, a leading delimiting
Vorliegend sind die Begrenzungselemente 24, 26 in der Seitenansicht keilförmig gestaltet und haben ebene Begrenzungsflächen 44 bzw. 42, die zumindest im Verlauf des Stabilisierungsabschnitts S parallel zur Solllage der Produkte 16, d.h. hier vertikal orientiert sind. Eine andere Form der Begrenzungselemente 24, 26 ist möglich. Die vor- bzw. nachlaufenden Begrenzungselemente 24, 26 sind jeweils in regelmässigen Abständen d1, d2 (siehe
Die weiteren Begrenzungselemente 28 werden bei der Bewegung des Nockenrads 30 entlang einer kreisförmigen Bewegungsbahn K bewegt, die über einen Winkel von 180° mit dem Endabschnitt U1 der Bewegungsbahn U der Begrenzungselemente 24, 26 übereinstimmt bzw. parallel dazu verläuft. Die Nocken 31 haben jeweils die ungefähre Form eines Kreissegments mit zwei im wesentlichen radial orientierten ersten und zweiten Flanken 31a, 31b mit einem Öffnungswinkel α von ca. 90° (siehe
Das Nockenrad 30 und das Förderorgan 46 für die vor- und nachlaufenden Begrenzungselemente 24, 26 werden über eine Antriebseinrichtung 40, die über ein Antriebselement 41 mit der Andrückeinrichtung 22 gekoppelt ist, angetrieben. Wie in

Das Nockenrad 30 hat den Vorteil, dass es im kritischen Anfangsbereich S1 der Stabilisierungsstrecke S auf einfache Weise ein Eindringen von Produktteilen in die Zwischenbereiche 29 verhindert, dabei aber nur rotiert und nicht über die gesamte Stabilisierungsstrecke S mitbewegt werden muss. Es ist einfach herzustellen und aufwandsarm anzutreiben.The

In einer alternativen Ausführungsform können die nachlaufenden Begrenzungselemente 26 mit einem Schwenkmechanismus ausgestattet sein, so dass die untere Kante 20 zwischen den Begrenzungselementen 24, 26 fixiert werden kann. Dies ist in
Im Anfangsbereich S1 überlappen die Bewegungsbahnen U, U' der vor- bzw. nachlaufenden und der weiteren Begrenzungselemente 24, 26, 28. Hier wird das weitere Begrenzungselement 28 funktionsmässig von einem nachlaufenden Begrenzungselement 26 abgelöst. Dazu fluchtet zu einem bestimmten Zeitpunkt die nach vorne gerichtete Begrenzungsfläche 42 mit der Führungsfläche 31a. Sobald das nachlaufende Begrenzungselement 26 die Produktposition 16 eingrenzt, wird das weitere Begrenzungselement 28 aus dem Förderstrom 54 entfernt. Dies geschieht vorzugsweise mittels einer mechanischen Kulissensteuerung mit einer Steuerkulisse 50. Ähnlich wie in
Im Endbereich S2 des Stabilisierungsabschnitts S nähern sich offene Greifer 58 den Produkten 16. Diese greifen die Produkte 16 im Bereich der nun eingegrenzten unteren Kante 20. Anschliessend werden die Greifer 14 der Fördereinrichtung 12 geöffnet und die Produkte an den Greiferförderer 56 übergeben.In the end region S2 of the stabilization section S,

Die Kombination von vor- und nachlaufenden Begrenzungselementen 24, 26 mit einem weiteren Begrenzungselement 28 hat den Vorteil, dass die vor- und nachlaufenden Begrenzungselemente 24, 26 verhältnismässig einfach und kompakt ausgeführt werden können. Indem die zu positionierende Kante 20 durch das weitere Begrenzungselement 28 bereits vor oder am Beginn des Stabilisierungsabschnitts S vorpositioniert wird, müssen die vor- und nachlaufenden Begrenzungselemente 24, 26 selbst keine grossen Strecken zurücklegen, um einzelne Produktteile einzufangen und in die Ideallage zu bringen. Eine einfache Stab- oder Keilform der vor- und nachlaufenden Begrenzungselemente 24, 26, deren Abmessung nur ein Bruchteil der Produktlänge zu sein braucht, ist daher ausreichend.

- Method according to Claim 1, characterized in that the further delimiting element (28) is removed from the conveying stream (54) again as early as the starting region (S1) of the stabilizing portion (S).
- Method according to Claim 1 or 2, characterized in that a plurality of trailing and leading delimiting elements (24, 26) are moved alternately one behind the other along a continuous circulatory path (U) which, at least in part, runs essentially parallel to the stabilizing portion (S) of the conveying section (11).
- Method according to one of the preceding claims, characterized in that the leading and trailing delimiting elements (24, 26) each have a delimiting surface (42, 44) which, at least over part of the stabilizing portion (S), is directed toward the articles (16) and is oriented preferably essentially parallel to the articles (16).
- Method according to one of the preceding claims, characterized in that the intermediate region (29) between in each case two receiving means (27) is covered by the further delimiting element (28) upstream of and/or in the starting region (S1) of the stabilizing portion (S), with the result that the second edge (20) of the article (16) can pass only into a receiving means (27).
- Method according to one of the preceding claims, characterized in that, over the course of the stabilizing portion (S), the leading delimiting elements (24) are moved out of a position in which they do not project into the conveying stream (54), in particular a position in which they run essentially as a tangent or secant in relation to their circulatory path (U), into a position in which they project into the conveying stream (54), in particular are pivoted into a position in which they run perpendicularly to the circulatory path (U).
- Method according to Claim 6, characterized in that the at least one further delimiting element (28) is moved along a continuous circulatory path (U') which, upstream of the stabilizing portion (S) of the conveying section (11), runs, at least in part, in the conveying .direction (F), and in that the further delimiting element (28) is introduced into the conveying stream (54) before the beginning of the stabilizing portion (S) and is removed from the conveying stream (54) in the starting region (S1) of the stabilizing portion (S) such that it no longer performs a delimiting action.
- Apparatus for implementing the method according to one of Claims 1-7, having a conveying arrangement (12) for retaining the articles in the region of a first edge (18), and for conveying in a conveying direction (F) along a conveying section (11), and having a plurality of delimiting elements (24, 26) which, in a stabilizing portion (S) of the conveying section (11), can be introduced into the conveying stream (54), moved along therewith and removed therefrom again, having:- at least one trailing delimiting element (26), which is capable of localizing the position of a second edge (20), which is located opposite the first edge (18), counter to the conveying direction (F);- at least one leading delimiting element (24), which is capable of localizing the position of the second edge (20) in the conveying direction (F), a receiving means (27) for the second edge (20) being formed, at least over the course of the stabilizing portion (S), between a respective leading delimiting element (24) and a delimiting element (26) which follows the latter in the conveying direction (F);- at least one further delimiting element (28), which is capable of localizing the position of the second edge (20) in and/or counter to the conveying direction (F);- a drive arrangement (40) for moving the leading and trailing delimiting elements (24, 26) along a continuous circulatory path (U);- a drive arrangement (40) for moving the further delimiting element (28),- the delimiting elements (24, 26, 28) being formed and driven such that the second edge (20) passes only into the receiving means (27) and not into the intermediate region (29) between two receiving means (27),- and the further delimiting element (28) being removed from the conveying stream over the course of the stabilizing portion (S).
- Apparatus according to Claim 8, characterized in that the circulatory path (U) of the leading and trailing delimiting elements (24, 26) in the stabilizing portion (S) of the conveying section (11) runs essentially parallel to the conveying section (11).
- Apparatus according to Claim 8 or 9, characterized by a cam wheel (30) with at least one cam (31) which is arranged in a rotatable manner at the beginning of the stabilizing portion (S), the further delimiting element (28) being formed by the at least one cam (31).
- Apparatus according to Claim 10, characterized in that the at least one cam (31) has essentially radially oriented first and second flanks (31a, 31b) and a lateral surface (31c) running in the circumferential direction therebetween.
- Apparatus according to Claim 10 or 11, characterized in that the cam wheel (30) and the leading and trailing delimiting elements (24, 26) are formed, and driven in a synchronized manner, such that the second flank (31b) is aligned with the leading delimiting element (24) and the first flank (31a) is aligned with the trailing delimiting element (26) at least at one point of the stabilizing section (S), preferably in each case in the starting region of the stabilizing section (S).
- Apparatus according to either of Claims 11 and 12, characterized in that the intermediate region (29) between two receiving means (27) is covered by the lateral surface (31c) at least in the starting region (S1) of the stabilizing section (S).
- Apparatus according to Claim 8 or 9, characterized in that the leading delimiting elements (24) can be moved, in particular pivoted, between a position in which they do not project into the conveying stream (54), in particular a position in which they run essentially as a tangent or secant in relation to their circulatory path (U), and a position in which they project into the conveying stream (54), in particular into a position in which they run perpendicularly to the circulatory path (U).
- Apparatus according to Claim 14, characterized in that the trailing and the further delimiting elements (26, 28) are formed, and driven in a synchronized manner, such that the trailing and the further delimiting elements (26, 28) are aligned with one another at least at one point of the stabilizing section (S), preferably in each case in the starting region (S1) of the stabilizing section (S).
