Description

Die vorliegende Erfindung betrifft eine Fördereinrichtung zum Zubringen von flächigen Erzeugnissen zu einer Verarbeitungsmaschine für Druckereiprodukte und eine Einrichtung zum Verarbeiten von Druckereiprodukten.The present invention relates to a conveyor device for feeding flat products to a processing machine for printed products and a device for processing printed products.

Eine Fördereinrichtung dieser Art ist in der älteren CH-Patentanmeldung Nr. 00 887/94-6, angemeldet am 24. März 1994, offenbart. Sie weist ein drehend angetriebenes Trägerrad auf, an dem in Umfangsrichtung verteilt Tragelemente befestigt sind, an welchen je ein Tragarm und Lenkorgan um zur Drehachse des Trägerrades parallelle Schwenkachsen angelenkt ist. Im freien Endbereich jedes Tragarmes ist an diesem ein zur Drehachse paralleller Lagerschaft angeordnet, an dem zwei zusammenwirkende, in Schliessrichtung vorgespannte Klemmbacken einer Klammer schwenkbar gelagert sind. Eine erste der Klemmbacken ist mit dem Lenkorgan verbunden, um die Klammer um ihre Anlenkung am Tragarm zu verschwenken. Sowohl die Schwenklage der Tragarme, als auch die Lage der Lenkorgane ist getrennt voneinander gesteuert, um die Klammer auch unabhängig von einer Schwenkbewegung der Tragarme zu verschwenken. Dies ermöglicht insbesondere das Bewegen der Klammer in Umlaufrichtung relativ zu den Tragelementen, wobei die Schwenklage der Klammern steuerbar ist, was besondere Vorteile beim Uebernehmen und Abgeben der Erzeugnisse sowie gegebenenfalls beim Vorbeiführen der Erzeugnisse in definierter Lage und mit gegebener Geschwindigkeit an Bearbeitungsstationen mit sich bringt. Vor der Uebernahme eines Erzeugnisses werden die Klammern in eine Lage verschwenkt, in welcher das durch die Klemmbacken gebildete Maul in Umlaufrichtung nach vorne gerichtet ist. Dabei kommt ein mit der in dieser Lage radial aussen liegenden zweiten Klemmbacke verbundenes Anschlagelement an einen Gegenanschlag am Tragarm zur Anlage, wodurch diese zweite Klemmbacke am weiteren Folgen der durch das Lenkorgan gesteuerten weiteren Schwenkbewegung der ersten Klemmbacke gehindert ist, was zum Oeffnen der Klammer führt. Zum Abgeben der Erzeugnisse an die Verarbeitungsmaschine werden die Klammern mit in etwa radial nach aussen gerichtetem Maul zwischen jeweils zwei aufeinanderfolgende Wandelemente der Verarbeitungsmaschine eingeführt. Der betreffende Tragarm wird dann in Umlaufrichtung nach vorne geschwenkt, bis sich die zweite Klemmbacke mit einer an ihrem freien Ende gelagerten Andrückwalze über das Erzeugnis am in Umlaufrichtung vorauslaufenden Wandelement abstützt. Beim anschliessenden Schwenken der ersten Klemmbacke mittels des Lenkorgans wird dadurch die zweite Klemmbacke am Mitschwenken gehindert, was das Oeffnen der Klammern und Freigeben des Erzeugnisses zur Folge hat.A conveyor of this type is disclosed in earlier CH patent application No. 00 887 / 94-6, filed on March 24, 1994. It has a rotatably driven carrier wheel, to which supporting elements distributed in the circumferential direction are fastened, to each of which a supporting arm and steering element are articulated about pivot axes parallel to the axis of rotation of the carrier wheel. In the free end region of each support arm there is arranged a bearing shaft parallel to the axis of rotation, on which two cooperating clamping jaws of a clamp, which are pretensioned in the closing direction, are pivotably mounted. A first of the clamping jaws is connected to the steering element in order to pivot the clip around its articulation on the support arm. Both the pivoting position of the support arms and the position of the steering members are controlled separately from one another in order to pivot the clamp independently of a pivoting movement of the support arms. In particular, this enables the clamp to be moved in the circumferential direction relative to the supporting elements, the pivoting position of the clamps being controllable, which has particular advantages when taking over and delivering the products and, if appropriate, when moving the products past in a defined position and at a given speed to processing stations. Before a product is taken over, the clamps are pivoted into a position in which the mouth formed by the clamping jaws is directed forward in the direction of rotation. In this case, a stop element connected to the second clamping jaw lying radially on the outside comes into contact with a counter stop Support arm to the system, whereby this second jaw is prevented from further following the further pivoting movement of the first jaw controlled by the steering element, which leads to the opening of the clamp. To deliver the products to the processing machine, the clamps are inserted with an approximately radially outwardly directed mouth between two successive wall elements of the processing machine. The support arm in question is then pivoted forward in the circumferential direction until the second clamping jaw is supported by a pressure roller mounted at its free end on the product on the wall element leading in the circumferential direction. When the first clamping jaw is subsequently pivoted by means of the steering member, the second clamping jaw is prevented from pivoting with it, which has the consequence of opening the clamps and releasing the product.

Diese Fördereinrichtung ist dazu bestimmt und geeignet, Erzeugnisse in von benachbarten Wandelementen gebildete, taschenförmige Aufnahmeteile einzuführen und durch Pressen gegen ein Wandelement freizugeben.This conveyor device is intended and suitable for introducing products into pocket-shaped receiving parts formed by adjacent wall elements and releasing them by pressing against a wall element.

Weiter ist eine Fördereinrichtung zum Zubringen von flächigen Erzeugnissen zu einer Verarbeitungsmaschine für Druckereiprodukte in der EP-A-0 606 550 und EP-A-0 606 549 sowie den entsprechenden US-Patentanmeldungen Nr. 08/173967 und 08/173374 offenbart. Sie weist ein drehend angetriebenes Trägerrad auf, an dem in Umfangsrichtung im Abstand steuerbare Klammern über Tragarm und Lenkorgan angeordnet sind. Tragarm und Lenkorgan sind jeweils am Trägerrad um zu dessen Drehachse parallelle Achsen schwenkbare gelagert, um gelenkviereckartig die Lage der jeweiligen Klammer in Abhängigkeit von der Schwenklage des betreffenden Tragarms zu steuern. Ist der Tragarm in Umlaufrichtung gesehen gegen hinten verschwenkt, ist das Maul der Klammer gegen vorne gerichtet. Sie nimmt diese Lage beim Durchlaufen eines Uebernahmebereichs ein, in welchem sie ein Erzeugnis bei dessen in Umlaufrichtung gesehen nachlaufenden Kante erfasst, das mittels eines Bandförderers tangential zur Bewegungsbahn der Klammer, aber mit bezüglich dieser geringerer Geschwindigkeit dem Uebernahmebereich zugeführt und im Uebernahmebereich gefördert wird. Beim Verschwenken des Tragarms aus seiner rückwärts gerichteten Endlage in eine etwa radiale Lage wird die Klammer in Abhängigkeit von der Bewegung des Tragarms entgegen der Umlaufrichtung verschwenkt, um dabei das Erzeugnis in einem Uebergabebereich zwischen Wandelemente einer Verarbeitungsmaschine für Druckereiprodukte einzuführen und dort an ein an einem der Wandelemente anliegenden Druckereiprodukt anzulegen oder gesteuert freizugeben. Die beiden Klemmbacken einer Klammer sind am betreffenden Tragarm schwenkbar gelagert, wobei die eine der Klemmbacken am Lenkorgan und die andere der Klemmbacken an einem kurbeltriebartigen Oeffnungsorgan angelenkt ist. Letzteres weist eine Folgerolle auf, mit der zum Oeffnen der Klammer im Uebernahme- und im Uebergabebereich je eine Oeffnungskulisse zusammenwirkt. Um das Erfassen der Erzeugnisse durch die Klammern im Uebernahmebereich zu gewährleisten, werden jene immer mit zur Umlaufrichtung gleicher Richtung, aber mit kleinerer Geschwindigkeit gefördert. Das Uebernehmen von im Uebernahmebereich, in Umlaufrichtung gesehen, stillstehenden Erzeugnissen ist in den genannten Dokumenten nicht erwähnt, noch ist die dort offenbarte Fördereinrichtung dazu vorgesehen.Furthermore, a conveyor device for feeding flat products to a processing machine for printed products is disclosed in EP-A-0 606 550 and EP-A-0 606 549 and the corresponding US patent applications No. 08/173967 and 08/173374. It has a rotatably driven carrier wheel, on which clamps, which are controllable at a distance in the circumferential direction, are arranged via the support arm and steering element. The support arm and the steering member are each mounted on the support wheel so as to be pivotable about axes parallel to its axis of rotation, in order to control the position of the respective clamp in a quadrangular manner as a function of the pivot position of the support arm in question. If the support arm is pivoted towards the rear, as seen in the direction of rotation, the mouth of the clamp is directed towards the front. It assumes this position when it passes through a takeover area which detects a product at its trailing edge, as seen in the direction of rotation, which is fed by means of a belt conveyor tangential to the path of movement of the clamp, but is conveyed to the take-over area at a lower speed and conveyed in the take-over area. When pivoting the support arm from its rearward end position into an approximately radial position, the clamp is pivoted against the direction of rotation depending on the movement of the support arm in order to introduce the product in a transfer area between wall elements of a processing machine for printed products and there to one of the Apply wall elements to the printed product or release them in a controlled manner. The two clamping jaws of a clamp are pivotably mounted on the relevant support arm, one of the clamping jaws being articulated on the steering element and the other of the clamping jaws being articulated on a crank mechanism-like opening element. The latter has a follow-up role with which an opening backdrop interacts in order to open the clip in the takeover and transfer area. In order to ensure that the products are grasped by the clamps in the takeover area, they are always conveyed in the same direction as the direction of circulation, but at a lower speed. The takeover of products which are stationary in the takeover area, seen in the direction of circulation, is not mentioned in the documents mentioned, nor is the conveyor device disclosed there intended for this purpose.

Das Oeffnen der Klammern ist ohne Abstützen der einen Klemmbacke am Tragarm oder an der Verarbeitungsmaschine ermöglicht.The conveyor device according to the invention has the advantages of the conveyor device disclosed in Swiss Patent Application No. 00 887 / 94-6, but additionally enables the clamps to be opened in any pivot position. The conveyor device according to the invention can thus be used in a wide variety of ways. The opening of the clips is possible without supporting the one jaw on the support arm or on the processing machine.

Die in der Figur 1 stark vereinfacht gezeigte Einrichtung zum Verarbeiten von Druckereiprodukten weist eine Fördereinrichtung 10 mit in Umlaufrichtung U hintereinander angeordneten Klammern 12 auf, die dazu bestimmt sind, beim Vorbeibewegen an einer Lieferstelle 14 jeweils ein Erzeugnis 16', im vorliegenden Fall einen gefalteten Druckbogen 16, ein sogenannter Beihefter, zu erfassen und einem Uebergabebereich 18 zuzuführen, wo die Erzeugnisse 16' an eine Verarbeitungsmaschine 20 abgegeben werden. Eine Verarbeitungsmaschine 20 dieser Art ist in der EP-A-0 550 828 und der entsprechenden US-A-5,324,014 gezeigt und ausführlich beschrieben. Sie weist um eine Trommelachse 22 herum in Umfangsrichtung gleichmässig verteilte Wandelemente 24 auf, die radial angeordnet sind und mit ihrem radial äusseren Ende je eine parallel zur Trommelachse 22 verlaufende sattelförmige Auflage 26 für die Druckbogen 16 und weitere zu verarbeitende Druckereiprodukte 27 bilden.The device for processing printed products shown in greatly simplified form in FIG. 1 has a conveying device 10 with clamps 12 arranged one behind the other in the direction of rotation U, which are intended to each have a product 16 ′, in the present case a folded printed sheet, as it moves past a delivery point 14 16, a so-called insert, to be recorded and fed to a transfer area 18, where the products 16 'are delivered to a processing machine 20. A processing machine 20 of this type is shown and described in detail in EP-A-0 550 828 and the corresponding US-A-5,324,014. It has wall elements 24 distributed uniformly in the circumferential direction around a drum axis 22, which are arranged radially and each form a saddle-shaped support 26 for the printed sheets 16 and other printed products 27 to be processed running parallel to the drum axis 22 with their radially outer end.

An einem Trägerrad 28 der Fördereinrichtung 10, das an einem Maschinengestell 30 mit parallel zur Trommelachse 22 verlaufender Drehachse 32 gelagert ist und das entgegengesetzt der Drehrichtung D der Verarbeitungsmaschine 20 in Umlaufrichtung U angetrieben ist, sind in Umfangsrichtung gleichmässig verteilt auslegerartige Tragelemente 34 befestigt, an denen je ein Tragarm 36 und ein Lenkorgan 38 schwenkbar gelagert ist. Die Tragelemente 34 laufen somit entlang einer in sich geschlossenen kreisförmigen Umlaufbahn um die Drehachse 32 um. Die Tragarme 36 sind in der Art eines zweiarmigen Winkelhebels ausgebildet, an dessen einem Arm 40 eine Klammer 12 schwenkbar und an dessen anderem Arm 42 eine Folgerolle 44 drehbar gelagert ist, wie dies insbesondere den Figuren 2 und 3 entnehmbar und weiter unten ausführlich beschrieben ist.On a carrier wheel 28 of the conveyor device 10, which on a machine frame 30 with parallel to the drum axis 22nd extending axis of rotation 32 is mounted and which is driven in the opposite direction to the direction of rotation D of the processing machine 20 in the circumferential direction U, cantilever-like support elements 34 are attached in the circumferential direction, on each of which a support arm 36 and a steering member 38 is pivotally mounted. The support elements 34 thus run along a closed circular orbit around the axis of rotation 32. The support arms 36 are designed in the manner of a two-armed angle lever, on one arm 40 of which a clamp 12 is pivotable and on the other arm 42 of which a follower roller 44 is rotatably mounted, as can be seen in particular from FIGS. 2 and 3 and is described in detail below.

Jede Klammer 12 weist zwei zusammenwirkende, ein Klammermaul 46 bildende Klemmbacken 48, 50 auf, von denen jeweils eine erste Klemmbacke 48 zum Verschwenken der Klammer 12 mit dem betreffenden Lenkorgan 38 verbunden ist. Am Lenkorgan 38 ist eine Steuerrolle 52 drehbar gelagert.Each clamp 12 has two interacting clamping jaws 48, 50 forming a clamping jaw 46, each of which a first clamping jaw 48 is connected to the relevant steering member 38 for pivoting the clamp 12. A control roller 52 is rotatably mounted on the steering member 38.

Ein am Maschinengestell 30 befestigter Steuerring 54, siehe auch Figur 4, weist zwei um das Trägerrad 28 herumverlaufende, in sich geschlossene, nutartige Steuerkulissen 56, 58 auf. In einer ersten Steuerkulisse 56 sind alle an den Tragarmen 36 gelagerten Folgerollen 44 geführt, wogegen in der radial innenliegenden zweiten Steuerkulisse 58 alle auf die Lenkorgane 38 einwirkenden Steuerrollen 52 geführt sind. Die erste Steuerkulisse 56 bestimmt somit die Schwenklage der Tragarme 36 und die zweite Steuerkulisse 58 die Schwenklage der an den Tragarmen 36 gelagerten Klammern 12. Der Steuerring 54 mit den Steuerkulissen 56, 58 und die damit zusammenwirkenden Folge- und Steuerrollen 44, 52 bilden somit eine Steuereinrichtung 60 zum getrennten Steuern der Tragarme 36 und Lenkorgane 38, um die Klammern 12 um ihre Anlenkung an den Tragarmen 36 auch unabhängig von der Schwenkbewegung der Tragarme 36 zu verschwenken.A control ring 54 fastened to the machine frame 30, see also FIG. 4, has two closed, groove-like control links 56, 58 which run around the carrier wheel 28. In a first control link 56 all follow rollers 44 mounted on the support arms 36 are guided, whereas in the radially inner second control link 58 all control rollers 52 acting on the steering members 38 are guided. The first control link 56 thus determines the pivot position of the support arms 36 and the second control link 58 the pivot position of the brackets 12 mounted on the support arms 36. The control ring 54 with the control links 56, 58 and the consequent follow-up and control rollers 44, 52 thus form one Control device 60 for separately controlling the support arms 36 and steering members 38 in order to pivot the brackets 12 about their articulation on the support arms 36 also independently of the pivoting movement of the support arms 36.

Weiter ist im Uebergabebereich 18 eine Oeffnungskulisse 62 ortsfest angeordnet, die dazu bestimmt ist, zum Oeffnen der Klammer 12 auf die zweite Klemmbacke 50 einzuwirken.Furthermore, an opening gate 62 is arranged in the transfer area 18, which is intended to act on the second clamping jaw 50 in order to open the clamp 12.

Die Klammern 12 sind dazu bestimmt, mit ihrem in Umlaufrichtung U gegen vorne gerichteten Klammermaul 46 bei der Lieferstelle 14 einen gefalteten Druckbogen 16 bei dessen Falz 66 zu fassen und mit der diesem gegenüberliegenden Kante 68 voraus dem Uebergabebereich 18 zuzuführen, an dessen Anfang ein Oeffnungsaggregat 70 angeordnet ist. Dieses ist dazu bestimmt, jeweils einen ersten Druckbogenteil 72 in einem dem Falz 66 gegenüberliegenden Randbereich zu fassen und vom anderen zweiten Druckbogenteil 74 abzuheben, so, dass jeweils ein Wandelement 24 der Verarbeitungsmaschine 20 zwischen die von einander abgehobenen Druckbogenteile 72, 74 einfahren kann. Das Oeffnungsaggregat 70 gibt dann den ersten Druckbogenteil 72 frei, wonach im Endbereich des Uebergabebereichs 18 mittels der Oeffnungskulisse 62 die Klammern 12 geöffnet werden, um die Druckbogen 16 freizugeben, die dann rittlings auf die sattelförmigen Auflagen 26, bzw. auf bereits auf diesen angeordnete Druckereiprodukte 27 fallen.The clamps 12 are intended to grasp a folded printed sheet 16 at the delivery point 14 with their clamp mouth 46 facing forward in the direction of rotation U and to feed it with the opposite edge 68 to the transfer area 18, at the beginning of which an opening unit 70 is arranged. This is intended in each case to grip a first printed sheet part 72 in an edge region opposite the fold 66 and to lift it off from the other second printed sheet part 74, so that in each case one wall element 24 of the processing machine 20 can move between the printed sheet parts 72, 74 which are lifted from one another. The opening unit 70 then releases the first printing sheet part 72, after which the clips 12 are opened in the end region of the transfer area 18 by means of the opening link 62 in order to release the printing sheets 16, which are then straddled the saddle-shaped supports 26 or printed products already arranged thereon 27 fall.

Eine Zubringeinrichtung 76 hat die Aufgabe, bei der Lieferstelle 14 für jede Klammer 12 ein Erzeugnis 16', im vorliegenden Fall einen Druckbogen 16, in der richtigen Lage bereitzustellen. Die in der Figur 1 gezeigte Zubringeinrichtung 76 ist in der älteren CH-Patentanmeldung Nr. 00 886/94-4 offenbart. Eine weitere, zum selben Zweck geeignete Zubringeinrichtung ist in der ebenfalls älteren CH-Patentanmeldung Nr. 00 887/94-6 gezeigt und beschrieben. Was den Aufbau und die Funktionsweise dieser Zubringeinrichtungen 76 betrifft, wird ausdrücklich auf diese Dokumente verwiesen.A feed device 76 has the task of providing a product 16 ′, in the present case a printed sheet 16, in the correct position at the delivery point 14 for each clip 12. The feed device 76 shown in FIG. 1 is disclosed in the earlier CH patent application No. 00 886 / 94-4. Another feed device suitable for the same purpose is shown and described in the also earlier CH patent application No. 00 887 / 94-6. With regard to the structure and mode of operation of these feed devices 76, reference is expressly made to these documents.

Der Aufbau der Klammern 12 und deren Steuerung wird nun anhand der Figuren 2 und 3 näher beschrieben. Der Tragarm 36 weist zwei identische Tragarmteile 78 auf, die je auf einer Seite des Tragelementes 34 angeordnet und mittels einer Anlenkachse 80 am Tragelement 34 gelagert sind. Beiderends sind diese Tragarmteile 78 über Lagerschäfte 82, 82' miteinander verbunden, wobei am ersten Lagerschaft 82 auf der einen Seite des Tragarms 36 die Folgerolle 44 und am zweiten Lagerschaft 82' auf der anderen Seite des Tragarm 36 die beiden Klemmbacken 48, 50 der Klammer 12 gelagert sind.The structure of the clamps 12 and their control will now be described with reference to Figures 2 and 3. The support arm 36 has two identical support arm parts 78, which are each arranged on one side of the support element 34 and are mounted on the support element 34 by means of a pivot axis 80. At both ends, these support arm parts 78 are connected to one another via bearing shafts 82, 82 ', the follow roller 44 on the first bearing shaft 82 on one side of the support arm 36 and the two clamping jaws 48, 50 of the clamp on the second bearing shaft 82' on the other side of the support arm 36 12 are stored.

Das Lenkorgan 38 weist einen aus zwei gleich geformten Teilhebeln 84 bestehenden zweiarmigen Steuerhebel 84'auf, die ebenfalls je auf einer Seite des Tragelements 34 angeordnet und mittels einer weiteren Anlenkachse 80' an diesem gelagert sind. Die beiden Teilhebel 84 sind beiderends über weitere Lagerschäfte 86, 86' miteinander verbunden, wobei am weiteren Lagerschaft 86 die Steuerrolle 52 drehbar gelagert ist und an weiteren Lagerschaft 86' ein schaftartiges Verbindungsglied 88 einer Koppel 90 angelenkt ist. Das Verbindungsglied 88 ist in einem Koppelrohr 92 verschiebbar geführt, wobei zwischen dem dem Steuerhebel 84 zugewandtem Ende des Koppelrohres 92 und dem dem Steuerhebel 84' abgewandten Ende des Verbindungsgliedes 88 eine Druckfeder 94 wirkt. Die Relativverschiebung zwischen dem Koppelrohr 92 und dem Verbindungsglied 88 in Längsrichtung der Koppel 90 ist durch einen Begrenzungsstift 96 gegeben, der einen langlochartigen Durchlass 98 im Verbindungsglied 88 durchgreift und am Koppelrohr 92 befestigt ist. Unter normalen Betriebsbedingungen nimmt das Koppelrohr 92 bezüglich dem Verbindungsglied 88 die in den Figuren 2 und 3 gezeigte Lage ein, in welcher das steuerhebelseitige Ende des Querdurchlasses 98 am Begrenzungsstift 96 anliegt.The steering member 38 has a two-armed control lever 84 ′ consisting of two identically shaped part levers 84, which are also each arranged on one side of the support element 34 and are mounted on this by means of a further articulation axis 80 ′. The two partial levers 84 are connected at both ends to one another via further bearing shafts 86, 86 ', the control roller 52 being rotatably mounted on the further bearing shaft 86 and a shaft-like connecting member 88 of a coupling 90 being articulated on further bearing shaft 86'. The connecting member 88 is slidably guided in a coupling tube 92, a compression spring 94 acting between the end of the coupling tube 92 facing the control lever 84 and the end of the connecting member 88 facing away from the control lever 84 '. The relative displacement between the coupling tube 92 and the connecting element 88 in the longitudinal direction of the coupling 90 is provided by a limiting pin 96 which passes through an elongated hole-like passage 98 in the connecting element 88 and is fastened to the coupling tube 92. Under normal operating conditions, the coupling tube 92 assumes the position shown in FIGS. 2 and 3 with respect to the connecting member 88, in which the end of the transverse passage 98 on the control lever side rests on the limiting pin 96.

Die erste Klemmbacke 48 besteht aus zwei miteinander drehfest verbundenen zungenartigen Klemmbackenteilen 48', die mittels eines Verbindungsstiftes 100 an eine Lasche 102 angelenkt sind, die andernends an das Koppelrohr 92 angelenkt ist.The first jaw 48 consists of two tongue-like jaw parts 48 'which are connected to one another in a rotationally fixed manner and which are articulated by means of a connecting pin 100 to a tab 102 which is articulated at the other end to the coupling tube 92.

Die bezüglich der Drehachse 32 in radialer Richtung gesehen relativ zur ersten Klemmbacke 48 aussen liegende zweite Klemmbacke 50 ist plattenartig ausgebildet, weist am ihrem, in Umlaufrichtung U gesehen, vorlaufenden und über die Klemmbackenteile 48' der ersten Klemmbacke vorstehenden freien Ende eine Andrückwalze 104 auf und ist im Mittelbereich mit einem Mitnehmeranschlag 106 versehen, der das innere Ende des Klammermauls 46 bildet. Selbstverständlich weist der Mitnehmeranschlag 106 Ausnehmungen auf, die von den Klemmbackenteilen 48' durchgriffen sind um die Relativbewegung zwischen den Klemmbacken 48, 50 zulassen. Mittels eines parallel zum Lagerschaft 82' verlaufenden weiteren Verbindungsstifts 108 ist die zweite Klemmbacke 50 mit den beiden gleichgeformten dreieckförmigen Teilen 110 eines Anschlagelementes 110' verbunden, welche Teile zwischen den beiden Tragarmteilen 78 auf dem Lagerschaft 82' frei drehbar sitzen. Das Anschlagelement 110' ist dazu bestimmt, mit einem die beiden Tragarmteile 78 miteinander verbindenden Anschlagstift 112 zusammenzuwirken. Beim Anliegen des Anschlagelements 110' am Anschlagstift 112 befindet sich die zweite Klemmbacke 50 in einer Endstellung in welcher sie in etwa rechtwinklig zum zugeordneten Arm 40 des Tragarms 36 verläuft. Aus dieser Stellung kann die zweite Klemmbacke 50 nur im Gegenuhrzeigersinn bewegt werden; Figur 3.The second clamping jaw 50, which is located on the outside with respect to the axis of rotation 32 in the radial direction relative to the first clamping jaw 48, is plate-like and has a pressure roller 104 at its free end, which, as seen in the direction of rotation U and which projects beyond the clamping jaw parts 48 'of the first clamping jaw, has and is provided in the central area with a driver stop 106, which forms the inner end of the clamp mouth 46. Of course, the driver stop 106 has recesses which are penetrated by the jaw parts 48 'to allow the relative movement between the jaws 48, 50. By means of a further connecting pin 108 running parallel to the bearing shaft 82 ', the second clamping jaw 50 is connected to the two identical triangular parts 110 of a stop element 110', which parts are freely rotatable between the two support arm parts 78 on the bearing shaft 82 '. The stop element 110 'is intended to cooperate with a stop pin 112 connecting the two support arm parts 78 to one another. When the stop element 110 ′ bears against the stop pin 112, the second clamping jaw 50 is in an end position in which it extends approximately at right angles to the associated arm 40 of the support arm 36. From this position, the second jaw 50 can only be moved counterclockwise; Figure 3.

Im Koppelrohr 92 ist eine eine Schliessfeder 114 für die Klemmbacken 48, 50 bildende Druckfeder angeordnet, die einerseits am klammerseitigen Ende des Koppelrohres 92 und andererseits an einer Zugstange 116 abgestützt ist, die im Innern des Koppelrohres 92 durch die Schliessfeder 114 hindurch verläuft und mittels eines Anlenkstifts 118 mit den Teilen 110 des Anschlagelements 110' verbunden ist. Die Schliessfeder 114 steht unter Vorspannung und wirkt einerseits über die Zugstange 116 auf die zweite Klemmbacke 50 und andererseits über die Lasche 102 auf die erste Klemmbacke 48 in Schliessrichtung ein. Die Kraft der Schliessfeder 114 ist kleiner als die Vorspannkraft der Druckfeder 94.Arranged in the coupling tube 92 is a compression spring forming a closing spring 114 for the clamping jaws 48, 50, which is supported on the one hand on the end of the coupling tube 92 on the clamp side and on the other hand on a pull rod 116 which is in the interior of the coupling tube 92 by the closing spring 114 runs through and is connected by means of a pivot pin 118 to the parts 110 of the stop element 110 '. The closing spring 114 is pretensioned and acts on the one hand via the pull rod 116 on the second clamping jaw 50 and on the other hand via the tab 102 on the first clamping jaw 48 in the closing direction. The force of the closing spring 114 is less than the biasing force of the compression spring 94.

Was soweit den Aufbau und die Funktionsweise der Klammer 12 und deren Steuerung betrifft, wird ausdrücklich auf die ältere CH-Patentanmeldung Nr. 00 887/94-6 verwiesen.As far as the structure and operation of the bracket 12 and its control are concerned, reference is expressly made to the older CH patent application No. 00 887 / 94-6.

Am Anlenkstift 118 ist weiter eine Oeffnungslasche 120 angelenkt, die andernends mit einem Dreieckhebel 122 gelenkig verbunden ist, der über eine die beiden Tragarmteile 78 miteinander verbindenden Achse 124 am Tragarm 36 schwenkbar gelagert ist. Am Dreieckhebel 122 ist eine Oeffnungsrolle 126 frei drehbar gelagert, die dazu bestimmt ist, mit der Oeffnungskulisse 62 zusammenzuwirken. Wie dies in der Figur 3 strichpunktiert angedeutet ist, wird durch Zusammenwirken der Oeffnungsrolle 126 mit der am Steuerring 54 befestigten Oeffnungskulisse 62 die zweite Klemmbacke 50 entgegen der Kraft der Schliessfeder 114 von der ersten Klemmbacke 48 abgehoben, um die Klammer 12 zu öffnen. Durch die Anlenkung der zweiten Klemmbacke 50 über ein Gestänge an die Oeffnungsrolle 126 kann der Bewegungsraum für die Erzeugnisse 16' freigehalten werden.An articulation tab 120 is further articulated on the pivot pin 118, which is articulated at the other end with a triangular lever 122 which is pivotably mounted on the support arm 36 via an axis 124 connecting the two support arm parts 78. An opening roller 126 is freely rotatably mounted on the triangular lever 122 and is intended to interact with the opening link 62. As indicated by dash-dotted lines in FIG. 3, the second clamping jaw 50 is lifted from the first clamping jaw 48 against the force of the closing spring 114 by the interaction of the opening roller 126 with the opening guide 62 attached to the control ring 54 in order to open the clamp 12. The movement space for the products 16 'can be kept free by the articulation of the second clamping jaw 50 via a linkage to the opening roller 126.

Die in den Figuren gezeigte Klammer 12 kann auf drei unterschiedliche Arten geöffnet werden:
Erstens durch Einwirken der Oeffnungskulisse 62 auf die Oeffnungsrolle 126, wodurch die zweite Klemmbacke 50 im Gegenuhrzeigersinn verschwenkt wird, wie dies in der Figur 3 strichpunktiert angedeutet ist. Die Schwenklage der ersten Klemmbacke 48 ist durch die Steuereinrichtung 60 gegeben.The clip 12 shown in the figures can be opened in three different ways:
Firstly, by the action of the opening link 62 on the opening roller 126, as a result of which the second clamping jaw 50 is pivoted in the counterclockwise direction, as is indicated by dash-dotted lines in FIG. 3. The swivel position of the The first clamping jaw 48 is provided by the control device 60.

Zweitens. Wird die Klammer 12 durch Verschwenken des Steuerhebels 84' mittels der Steuereinrichtung 60 im Uhrzeigersinn verschwenkt und kommt dabei das Anschlagelement 110' am Anschlagstift 112 zur Anlage, ist beim gleichsinnigen weiteren Verschwenken der Klammer 12 die zweite Klemmbacke 50 am Folgen der Schwenkbewegung der ersten Klemmbacke 48 gehindert, sodass sich die beiden Klemmbacken 48, 50 ebenfalls voneinander abheben. Dies ist in der Figur 3 mit der gestrichelt gezeigten Schwenklage der ersten Klemmbacke 48 angedeutet.Secondly. If the clamp 12 is pivoted clockwise by means of the control device 60 by pivoting the control lever 84 'and the stop element 110' comes to rest against the stop pin 112, when the clamp 12 is pivoted further in the same direction, the second clamping jaw 50 follows the pivoting movement of the first clamping jaw 48 prevented, so that the two jaws 48, 50 also stand out from each other. This is indicated in FIG. 3 with the pivoted position of the first clamping jaw 48 shown in dashed lines.

Drittens, kann die Klammer 12 dadurch geöffnet werden, dass mit einem Wandelement 24 der Verarbeitungsmaschine 20 auf die Andrückwalze 104 und somit auf die zweite Klemmbacke 50 im Gegenuhrzeigersinn eingewirkt wird, wie dies ausführlich in der älteren CH-Patentanmeldung 00 887/94-6 offenbart ist. Diese Betriebsart erlaubt das Andrücken der Erzeugnisse 16' an ein am Wandelement 24 anliegendes Druckereiprodukt 27.Third, the clamp 12 can be opened by acting with a wall element 24 of the processing machine 20 on the pressure roller 104 and thus on the second clamping jaw 50 in the counterclockwise direction, as is disclosed in detail in the earlier CH patent application 00 887 / 94-6 is. This operating mode allows the products 16 ′ to be pressed against a printed product 27 lying against the wall element 24.

Wie dies besonders der Figur 4 entnehmbar ist, werden die Klammern 12 bevor sie die Lieferstelle 14 erreichen auf die beschriebene zweite Art geöffnet um mit, in Umlaufrichtung U gesehen, nach vorne gerichtetem offenem Klammermaul 46 ein von einem Stapel mittels einer gestrichelt angedeuteten Saugkopfanordnung 128 abgehobenes Erzeugnis 16' bei dessen nachlaufender Kante, bei gefalteten Druckbogen 16 bei deren Falz 66 zu fassen. Dabei läuft die geöffnete Klammer 12 mit ihrem Mitnehmeranschlag 106 auf das Erzeugnis 16' auf und nimmt es in Umlaufrichtung U mit. Durch Verschwenken der ersten Klemmbacke 48 in Gegenuhrzeigersinn, wird die Klammer 12 geschlossen, wonach das Erzeugnis 16 im Klammermaul 46 festgehalten ist. Weiter ist der Figur 4 entnehmbar, dass beim Auflaufen der Klammer 12 auf das zu erfassende Erzeugnis 16' der Tragarm 36 mittels der Steuereinrichtung 60 entgegen der Umlaufrichtung U verschwenkt wird, was dazu führt, dass die Relativgeschwindigkeit zwischen der Klammer 12 und den zu erfassenden Erzeugnissen 16' reduziert ist gegenüber der Geschwindigkeit, die die Klammer 12 einnehmen würde, falls der Tragarm 36 bezüglich dem Trägerrad 28 seine Schwenklage beibehalten würde. Dieses Reduzieren der Geschwindigkeit ermöglicht eine schonende Behandlung der Erzeugnisse 16' und eine hohe Verarbeitungskapazität der Einrichtung. Bei geschlossenem Klammermaul 46 ist die Schwenklage der Klammer 12 durch die Steuereinrichtung 60 über das Lenkorgan 38 gegeben.As can be seen particularly from FIG. 4, the clamps 12 are opened in the second manner described before they reach the delivery point 14, with an open clamp mouth 46, viewed in the direction of rotation U and facing forward, lifted from a stack by means of a suction head arrangement 128 indicated by dashed lines Product 16 'at its trailing edge, with folded printed sheets 16 at the fold 66. The open clamp 12 runs with its driver stop 106 onto the product 16 'and takes it along in the direction of rotation U. By pivoting the first jaw 48 counterclockwise, the clamp 12 is closed, after which the product 16 is held in the clamp mouth 46. It can also be seen from FIG. 4 that when it comes up the bracket 12 on the product 16 'to be detected, the support arm 36 is pivoted by means of the control device 60 against the circumferential direction U, which means that the relative speed between the bracket 12 and the products 16' to be detected is reduced compared to the speed which the Bracket 12 would take if the support arm 36 would maintain its pivot position with respect to the carrier wheel 28. This reduction in speed enables gentle treatment of the products 16 'and a high processing capacity of the device. When the clamp jaw 46 is closed, the pivot position of the clamp 12 is given by the control device 60 via the steering member 38.

Die bezüglich dem nachlaufenden Falz 66 vorlaufende Kante 68 wird mittels eines Führungsblechs 130 geführt um die Druckbogen 16 am nach rückwärts Biegen infolge der Einwirkung des Fahrtwindes zu hindern. Nach der Uebernahme eines Druckbogens 16 werden die Tragarme 36 jeweils in Umlaufrichtung U verschwenkt, wonach die Einwirkung des Fahrtwindes auf die Erzeugnisse 16' vermindert ist.The leading edge 68 with respect to the trailing fold 66 is guided by means of a guide plate 130 in order to prevent the printed sheets 16 from bending backwards as a result of the action of the driving wind. After a printing sheet 16 has been taken over, the support arms 36 are each pivoted in the circumferential direction U, after which the effect of the driving wind on the products 16 'is reduced.

Anhand der Figur 5 wird nun das Oeffnen und anschliessende Ablegen der gefalteten Druckbogen 16 näher beschrieben. Das Oeffnungsaggregat 64 weist eine in Richtung des Pfeiles O drehend angetriebene Oeffnungswalze 132 auf, die mit einem Saugkopf 134 versehen ist, der über eine nicht gezeigte Ventilanordnung innerhalb eines bestimmten Drehbereichs der Oeffnungswalze 132 mit einer Unterdruckquelle verbunden ist. Der Saugkopf 134 ist dazu bestimmt, jeweils den dem Oeffnungsaggregat 70 zugewandten ersten Druckbogenteil 72 in einem dem Falz 66 gegenüberliegendem Randbereich zu fassen und festzuhalten bis jeweils ein Wandelement 24 der Verarbeitungsmaschine 20 zwischen die so voneinander abgehobenen Druckbogenteile 72, 74 eingefahren ist. Um das Erfassen des ersten Druckbogenteils 72 durch den Saugkopf 134 sicherzustellen, wird die vorauslaufende Kante 68 des ersten Druckbogenteils 72 mittels entlang einer geschlossenen Bewegungsbahn 136 umlaufend angetriebenen Nocken 138 geführt. Vorzugsweise sind die Nocken 138 an einer Kette angeordnet, die einerseits um die Achse der Oeffnungswalze 132 und andererseits um ein dieser vorgelagertes Umlenkrad 140 geführt ist. Derartige Oeffnungsaggregate 70 sind allgemein bekannt. Das Oeffnungsaggregat 70 ist am Maschinengestell 30 verstellbar angeordnet, um eine Anpassung an die zu verarbeitenden Erzeugnisse 16' zu ermöglichen. Um die vorlaufende Kante 68 der Druckbogen 16 zur Bewegungsbahn 136 der Nocken 138 zu leiten, ist ein weiteres Führungsblech 130' dem Oeffnungsaggregat 70 vorgelagert.The opening and subsequent depositing of the folded printed sheets 16 will now be described in more detail with reference to FIG. 5. The opening unit 64 has an opening roller 132 which is driven to rotate in the direction of the arrow O and is provided with a suction head 134 which is connected via a valve arrangement (not shown) to a source of negative pressure within a specific rotation range of the opening roller 132. The suction head 134 is intended to grasp and hold the first printed sheet part 72 facing the opening unit 70 in an edge region opposite the fold 66 until a wall element 24 of the processing machine 20 is inserted between the printed sheet parts 72, 74 so lifted from each other. In order to ensure that the first printing sheet part 72 is gripped by the suction head 134, the leading one Edge 68 of the first printed sheet part 72 is guided by means of cams 138 which are driven circumferentially along a closed movement path 136. The cams 138 are preferably arranged on a chain, which is guided on the one hand around the axis of the opening roller 132 and on the other hand around a deflection wheel 140 upstream of the latter. Such opening units 70 are generally known. The opening assembly 70 is adjustably arranged on the machine frame 30 in order to enable adaptation to the products 16 'to be processed. In order to guide the leading edge 68 of the printed sheets 16 to the movement path 136 of the cams 138, a further guide plate 130 ′ is arranged in front of the opening unit 70.

Wie dies der Figur 4 entnehmbar ist, werden die Klammern 12, bevor die vorlaufende Kante 68 der Druckbogen 16 jeweils das Oeffnungsaggregat 70 erreicht, durch Verschwenken des Tragarms 36 verzögert und dann wieder beschleunigt, um sicherzustellen, dass der erste Druckbogenteil 72 an einen Nocken 138 zur Anlage gelangt.As can be seen in FIG. 4, the clamps 12 are decelerated by pivoting the support arm 36 before the leading edge 68 of the printed sheets 16 respectively reaches the opening unit 70 and then accelerated again to ensure that the first printed sheet part 72 is attached to a cam 138 comes to the plant.

Den Figuren 4 und 5 ist entnehmbar, dass in einem Anfangsabschnitt des Uebergabebereichs 18 die Tragarme 36 gleichgerichtet der Umlaufrichtung U gegen vorne und gleichzeitig die Klammern 12 über das Lenkorgan 38 in entgegengesetzter Richtung verschwenkt werden, so, dass im Uebergabebereich 18 das Klammermaul 46 im wesentlichen mit dem betreffenden Wandelement 24 fluchtet und auf dieses zu ausgerichtet ist. Im Endabschnitt des Uebergabebereichs 18 läuft nun die Oeffnungsrolle 126 auf die Oeffnungskulisse 62 auf, wodurch die Klammer 12 auf die weiter oben beschriebene erste Art geöffnet wird, um den Druckbogen 16 freizugeben. Dieser fällt nun rittlingsweise auf die Auflage 26. Nach dem Oeffnen der Klammer 12 wird der betreffende Tragarm 36 wieder entgegen der Umlaufrichtung U verschwenkt, um zu verhindern, dass die Klammer 12 mit der Verarbeitungsmaschine 20, bzw. den auf die Wandelemente 24 abgelegten Druckereiprodukte 27 und Druckbogen 16 in Berührung kommt.It can be seen from FIGS. 4 and 5 that in an initial section of the transfer area 18 the support arms 36 are pivoted in the opposite direction to the direction of rotation U toward the front and at the same time the clamps 12 are pivoted in the opposite direction via the steering member 38, so that in the transfer area 18 the clamp mouth 46 essentially is aligned with the relevant wall element 24 and is aligned with it. In the end section of the transfer area 18, the opening roller 126 now runs onto the opening backdrop 62, as a result of which the clip 12 is opened in the first manner described above in order to release the printing sheet 16. This now straddles the support 26. After opening the clamp 12, the relevant support arm 36 is pivoted again counter to the direction of rotation U in order to prevent the clamp 12 from being processed by the processing machine 20 or by the wall elements 24 stored printed products 27 and sheet 16 comes into contact.

Figur 6 zeigt jeweils einen Teil des Oeffnungsaggregats 70, ein Wandelement 24 der Verarbeitungsmaschine 20 sowie eine einen aussermittig gefalteten Druckbogen 16 haltende Klammer 12. In der in der Figur 6 oben gezeigten Variante wird der Druckbogen 16 derart gehalten, dass der im Vergleich zum zweiten Druckbogenteil 74 kürzere erste Druckbogenteil 72 dem Oeffnungsaggregat 70 zugewandt und der zweite Druckbogenteil 74 der Drehachse 32 zugewandt ist. Der zweite Druckbogenteil 74 wird mit seiner vorlaufenden Kante 68 voraus zwischen das gezeigte Wandelement 24 und das diesem in Drehrichtung D vorlaufende Wandelement 24 eingeführt. Der erste Druckbogenteil 72 wird vom Saugkopf 134 gehalten und um die Oeffnungswalze 132 gebogen, während dem sich das Wandelement 24 unter der Oeffnungswalze 132 hindurch bewegt und am zweiten Druckbogenteil 74 zur Anlage kommt und diesen mitnimmt. Anschliessend wird der Saugkopf 134 gelüftet, wodurch nun die beiden Druckbogenteile 72, 74 das Wandelement 24 mit der Auflage 26 von oben umgreifen.FIG. 6 each shows a part of the opening unit 70, a wall element 24 of the processing machine 20 and a clip 12 holding an eccentrically folded printed sheet 16. In the variant shown in FIG. 6 above, the printed sheet 16 is held in such a way that it is compared to the second printed sheet part 74 shorter first press sheet part 72 faces the opening unit 70 and the second press sheet part 74 faces the axis of rotation 32. The second printed sheet part 74 is inserted with its leading edge 68 ahead between the wall element 24 shown and the wall element 24 leading it in the direction of rotation D. The first sheet part 72 is held by the suction head 134 and bent around the opening roller 132, during which the wall element 24 moves under the opening roller 132 and comes to rest on the second sheet part 74 and takes it along. The suction head 134 is then released, as a result of which the two pressure sheet parts 72, 74 now grip the wall element 24 with the support 26 from above.

In der in der Figur 6 unten gezeigten Variante ist der Druckbogen 16 derart in der Klammer 12 gehalten, dass der dem Oeffnungsaggregat 70 zugewandte erste Druckbogenteil 72 über den der Drehachse 32 zugewandten zweiten Druckbogenteil 74 vorsteht. Wie dies mit dem Pfeil A angedeutet ist, ist in diesem Fall das Oeffnungsaggregat 70 im Vergleich zur oben gezeigten Variante entgegen der Drehrichtung D versetzt angeordnet. Dies stellt nun sicher, dass der längere erste Druckbogenteil 72 vom Saugkopf 134 erfasst werden kann, bevor er in die Bewegungsbahn der Wandelemente 24 vorsteht. Wie dies strichpunktiert angedeutet ist, kann sich dabei das Wandelement 24 unter der Oeffnungswalze 132 und dem um diese gebogenen ersten Druckbogenteil 72 vorbei bewegen, wonach der Saugkopf 134 gelüftet wird. Der erste Druckbogenteil 72 kommt somit an der Rückseite des Wandelements 24 zur Anlage, wogegen der zweite Druckbogenteil 74 nun mit seiner vorlaufenden Kante 68' voraus zwischen das Wandelement 24 und das diesem in Umlaufrichtung U vorlaufende Wandelement eingeführt wird, wie mit ausgezogenen Linien gezeigt. Die Druckbogenteile 72, 74 umgreifen somit wiederum von oben das Wandelement 24 mit der Auflage 26.In the variant shown at the bottom in FIG. 6, the printed sheet 16 is held in the clamp 12 such that the first printed sheet part 72 facing the opening unit 70 protrudes beyond the second printed sheet part 74 facing the axis of rotation 32. As indicated by the arrow A, in this case the opening unit 70 is offset from the direction of rotation D in comparison to the variant shown above. This now ensures that the longer first printed sheet part 72 can be gripped by the suction head 134 before it protrudes into the movement path of the wall elements 24. As is indicated by dash-dotted lines, the wall element 24 can move under the opening roller 132 and the first pressure sheet part 72 bent around it, after which the suction head 134 is aired. The first printed sheet part 72 thus comes to rest on the back of the wall element 24, whereas the second printed sheet part 74 is now inserted with its leading edge 68 'ahead between the wall element 24 and the wall element leading in the direction of rotation U, as shown in solid lines. The printed sheet parts 72, 74 thus in turn encompass the wall element 24 with the support 26 from above.

Dadurch, dass sowohl der Tragarm 36 als auch das Lenkorgan 38 unabhängig voneinander steuerbar sind und somit die Lage der Klammer 12 bezüglich dem Trägerrad 28 in erheblichem Masse verändert werden kann und die Position des Oeffnungsaggregates 70 einstellbar ist, können unterschiedlichst formatige und unterschiedlichst gefaltete Druckbogen 16 verarbeitet werden.The fact that both the support arm 36 and the steering member 38 can be controlled independently of one another and thus the position of the clamp 12 with respect to the carrier wheel 28 can be changed to a considerable extent and the position of the opening unit 70 can be adjusted, printing sheets 16 of various formats and folded in various ways can are processed.

Mit der oben beschriebenen Einrichtung können selbstverständlich auch Druckbogen 16 oder anderartige Erzeugnisse 16', wie Karten und dergleichen, in von benachbarten Wandelementen 24 gebildete taschenartige Aufnahmeteile 142 eingeführt werden. Wie dies anhand der Figur 5 einfach vorstellbar ist, ist dazu die Phasenlage zwischen der Verarbeitungsmaschine 20 und der Fördereinrichtung 10 um einen halben Takt zu verschieben und das Oeffnungsaggregat 70 ausser den Einwirkbereich auf die Erzeugnisse 16' zu bringen oder wenigstens den Saugkopf 134 dauernd von der Unterdruckquelle zu trennen.With the device described above, of course, printed sheets 16 or other products 16 ′, such as cards and the like, can also be introduced into pocket-like receiving parts 142 formed by adjacent wall elements 24. As can be easily imagined with reference to FIG. 5, the phase position between the processing machine 20 and the conveying device 10 has to be shifted by half a cycle and the opening unit 70 has to be moved beyond the area of influence on the products 16 'or at least the suction head 134 has to be moved continuously from the Separate vacuum source.

Auch können mit der Fördereinrichtung 10 Erzeugnisse 16' an die Wandelemente 24 oder an diesen anliegende Druckereiprodukte 27 zur Anlage gebracht und an diese angedrückt werden, wie dies in der älteren CH-Patentanmeldung Nr. 00 887/94-6 ausführlich beschrieben ist. In diesem Fall entfaltet die Oeffnungskulisse 62 keine Wirkung. Sie ist deshalb wegnehmbar am Steuerring 54 befestigt. Es ist selbstverständlich auch denkbar, die Oeffnungskulisse 62 bewegbar anzuordnen und mittels eines Steuerelementes, beispielsweise eines Zylinderkolbenaggregates, in und ausser Arbeitsstellung zu verbringen.Products 16 'can also be brought into contact with the wall elements 24 or printed products 27 lying against them with the conveyor device 10 and pressed onto them, as is described in detail in the older Swiss patent application No. 00 887 / 94-6. In this case, the opening gate 62 has no effect. It is therefore removably attached to the control ring 54. It is of course also conceivable for the opening backdrop 62 Arranged movably and by means of a control element, for example a cylinder-piston unit, in and out of working position.

Es ist auch denkbar, die Klammern 12 zum Uebernehmen eines Erzeugnisses 16' mittels einer Oeffnungskulisse 62 zu öffnen. In diesem Fall kann auf den Anschlagstift 112 verzichtet werden.It is also conceivable to open the clips 12 for taking over a product 16 'by means of an opening link 62. In this case, the stop pin 112 can be dispensed with.

Es sei auch erwähnt, dass die Tragelemente 34 an einem endlosen Zugorgan, beispielsweise einer Kette, angeordnet sein können, das um Umlenkräder oder in einem Kanal geführt ist. Die Umlaufbahn der Tragelemente 34 kann somit beliebige Form aufweisen.It should also be mentioned that the support elements 34 can be arranged on an endless traction element, for example a chain, which is guided around deflection wheels or in a channel. The orbit of the support elements 34 can thus have any shape.

In den Figuren ist eine trommelartig ausgebildete Verarbeitungsmaschine 20 gezeigt. Es ist aber auch möglich, dass die Wandelemente 24 an einem Rundlauf angeordnet sind, so, dass sie beispielsweise entlang einer langgestreckten Bewegungsbahn umlaufen.In the figures, a processing machine 20 designed in the form of a drum is shown. However, it is also possible for the wall elements 24 to be arranged on a concentric run so that they run for example along an elongated movement path.

Der vollständigkeitshalber sei erwähnt, dass auch auf die Andrückwalze 104 oder ein gleichwirkendes Element verzichtet werden kann, falls mit der Fördereinrichtung 10 die Erzeugnisse 16' nicht gegen ein Wandelement 24 gedrückt werden sollen.For the sake of completeness, it should be mentioned that the pressure roller 104 or an element having the same effect can also be dispensed with if the products 16 ′ are not to be pressed against a wall element 24 by the conveying device 10.
