Abstract

A guided endless, revolvingly driven traction element is equipped with controlled gripper units or grippers arranged in spaced relationship from each other. These gripper units are adapted to grip one margin of the paper products which constitutes a lateral marginal edge of the product as seen in the transport direction thereof. The gripper units have substantially planar clamping faces inclined at the same direction with respect to the traction element for stiffening that portion of the transported paper products which laterally project from the gripper units. The transported printed products thus have imparted thereto a corrugation or undulation extending transversely with respect to the transport direction which results in the desired stiffening of the products.

Description

Die Erfindung betrifft eine Einrichtung der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a device of the type mentioned in the preamble of claim 1.

Eine solche Einrichtung ist vorbekannt und einer ihrer wesentlichen Vorteile besteht darin, dass sie ohne Anpassung an das Format der zu transportierenden Papierprodukte auskommt, vorausgesetzt, dass die zu fassenden, seitlichen Ränder aufeinanderfolgender Papierprodukte miteinander einigermassen fluchten. Andererseits bringt es das einseitige seitliche Fassen der Papierprodukte mit sich, dass diese namentlich bei höheren Transportgeschwindigkeiten durch den Fahrtwind zum «Herumflattern» d.h. zum Zerknüllen gebracht werden. Daher sind bei der bekannten Einrichtung ortsfeste Führungsschienen entlang des gesamten Förderweges für beide Flachseiten der Produkte vorgesehen. Will man bei dieser bekannten Einrichtung den Verlauf des Förderweges ändern, dann sind auch die Führungsschienen der bekannten Einrichtung dem neuen Verlauf anzupassen.Such a device is previously known and one of its main advantages is that it does not need to be adapted to the format of the paper products to be transported, provided that the lateral edges of successive paper products to be gripped are somewhat aligned with one another. On the other hand, the one-sided grasping of the paper products means that they flutter around, especially at higher transport speeds, due to the wind. be made to crumple. Therefore, in the known device, stationary guide rails are provided for both flat sides of the products along the entire conveying path. If you want to change the course of the conveyor path in this known device, then the guide rails of the known device must be adapted to the new course.

Mit einer anderen, bekannten Fördervorrichtung (GB-PS 752322), die ebenfalls an den einen seitlichen Rand der Papierprodukte angreift, wurde angestrebt, ohne Führungsschienen das Flattern der transportierten Papierprodukte zu verhindern. Diese weitere, vorbekannte Fördervorrichtung beruhte auf dem Grundgedanken, die Biegsamkeit der zu transportierenden Papierprodukte um zur Förderrichtung parallele Biegeachsen praktisch aufzuheben. Um diesen Grundgedanken zu verwirklichen, ist diese weitere Fördervorrichtung nicht mit Greifern im engeren Sinne bestückt, sondern mit zwei Reihen von scheibenförmigen, parallelachsigen, an ein endlos umlaufendes Zugorgan gekoppelten Mitnehmern bestückt, die umfangsseitig beispielsweise mit Gummi belegt sind. Diese Mitnehmer sind so angeordnet, dass die Mitnehmer der einen Reihe zwischen zwei Mitnehmer der anderen Reihe zu liegen kommen und federnd auf diese vorgespa nnt sind. Zum Beschikken mit Papierprodukten werden bei dieservorbekannten Fördervorrichtung die beiden Reihen der Mitnehmer durch entsprechende Kulissen auseinandergedrängt, die Papierprodukte dazwischen eingeführt und dann die Mitnehmer wieder freigegeben. Dies hatzur Folge, dass den Papierprodukten eine querzur Förderrichtung verlaufende Wellenform aufgezwungen wird, was die erwünschte Versteifung ergibt. Da bei dieser vorbekannten Fördervorrichtung aber jeder Mitnehmer der einen Reihe mit zwei Mitnehmern der anderen Reihezusammenwirkt, ist jede der aufgezwungenen Wellen sowohl an ihrer Front als auch an ihrem Rücken festgeklemmt so dass ein «Atmen», d.h. eine Streckung und/oder eine Stauchung der nun wellenförmigen Form der transportierten Papierprodukte nicht ohne weiteres möglich ist. Dies hat aber zur Folge, dass beim Durchlaufen von Kurven, sei es in der Ebene oder quer zur Ebene der Papierprodukte, sich bei der bekannten Fördervorrichtung kleine Relativverschiebungen zwischen den Mitnehmern einerseits und den Papierprodukten andererseits ergeben, oder - falls die Papierprodukte in einem Schuppenstrom anfallen - zwischen benachbarten Papierprodukten. Diese relativen Verschiebungen sind aber für die Papierprodukte schädlich, da entweder die mit Gummi belegten Mitnehmer auf den Papierprodukten «radieren» und/oder aufeinanderliegende Produkte aneinander reiben.With another known conveyor device (GB-PS 752322), which also engages the one side edge of the paper products, the aim was to prevent the fluttering of the transported paper products without guide rails. This further, previously known conveying device was based on the basic idea of practically eliminating the flexibility of the paper products to be transported in order to bend axes parallel to the conveying direction. In order to realize this basic idea, this further conveying device is not equipped with grippers in the narrower sense, but with two rows of disk-shaped, parallel-axis drivers coupled to an endlessly rotating traction element, which are circumferentially covered with rubber, for example. These drivers are arranged in such a way that the drivers of one row come to lie between two drivers of the other row and are resiliently pretensioned thereon. In order to load paper products with this known conveyor device, the two rows of drivers are pushed apart by appropriate backdrops, the paper products are inserted between them and then the drivers are released again. As a result, the paper products are forced to have a wave shape transverse to the conveying direction, which gives the desired stiffening. However, since in this known conveyor device each driver of the one row interacts with two drivers of the other row, each of the imposed shafts is clamped on both its front and its back so that «breathing», i.e. stretching and / or compressing the now wavy shape of the transported paper products is not readily possible. However, this has the consequence that when traversing curves, be it in the plane or transversely to the plane of the paper products, there are small relative shifts in the known conveying device between the drivers on the one hand and the paper products on the other hand, or - if the paper products occur in a stream of shingles - between neighboring paper products. However, these relative shifts are detrimental to the paper products, since either the rubber-coated drivers “erase” on the paper products and / or products lying on top of one another rub against one another.

Es ist daher ein Zweck der Erfindung, eine Einrichtung der eingangs genannten Art zu schaffen, die diese Nachteile vermeidet.It is therefore a purpose of the invention to provide a device of the type mentioned at the outset which avoids these disadvantages.

Zu diesem Zweck weist die vorgeschlagene Einrichtung die im Kennzeichen des Patentanspruches 1 angegebenen Merkmale auf.For this purpose, the proposed device has the features specified in the characterizing part of patent claim 1.

Da die im wesentlichen ebenen Klemmflächen der Greifer in bezug auf das Zugorgan gleichsinnig geneigt sind, zwingen sie den Papierprodukten ebenfalls eine quer zum Zugorgan verlaufende Wellenform auf, aber die Greifer klemmen nur entweder den Rücken oder die Front dieser Wellen, so dass die Front bzw. der Rücken sich strecken bzw. sich stauchen lässt, ohne dass es zu den genannten Relativverschiebungen käme.Since the essentially flat clamping surfaces of the grippers are inclined in the same direction with respect to the traction element, they also force the paper products onto a wave shape running transversely to the traction element, but the grippers only clamp either the back or the front of these shafts, so that the front or the back can be stretched or squeezed without causing the relative shifts mentioned.

Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen definiert.Preferred embodiments are defined in the dependent claims.

Nachstehend ist ein Ausführungsbeispiel der vorgeschlagenen Einrichtung an Hand der Zeichnung näher beschrieben. Es zeigt:

  • Fig. 1 eine schematische Seitenansicht der Aufgabestation einer Einrichtung,
  • Fig. 2 in etwas vergrössertem Massstab eine Draufsicht aus Richtung des Pfeiles A der Fig. 1 auf die Einrichtung der Fig. 1,
  • Fig. 3 in vergrössertem Massstab eine Ansicht aus Richtung der Linie B-B der Fig. 2, und
  • Fig.4 in vergrössertem Massstab eine Seitenansicht zweier aufeinanderfolgender Greifer, links offen - rechts in Schliessstellung.
An embodiment of the proposed device is described in more detail with reference to the drawing. It shows:
  • 1 is a schematic side view of the feed station of a device,
  • 2 is a somewhat enlarged scale a plan view from the direction of arrow A of FIG. 1 of the device of FIG. 1,
  • Fig. 3 on an enlarged scale a view from the direction of line BB of Fig. 2, and
  • Fig. 4 on an enlarged scale a side view of two successive grippers, open on the left - right in the closed position.

Zunächst wird nur auf Fig. 1 und 2 Bezug genommen. Ein Förderband 11 mit der durch einen Pfeil 12 angegebenen Förderrichtung führt Druckprodukte 13 - hier in Form eines Schuppenstromes S-der Einrichtung 10 zu, von der in Fig. 1 nur der der Übernahme des Schuppenstromes S dienende Übernahmeabschnitt und der Anfang des förderaktiven Trums gezeigt ist.First, reference is made only to FIGS. 1 and 2. A conveyor belt 11 with the conveying direction indicated by an arrow 12 feeds printed products 13 - here in the form of a shingled stream S - to the device 10, of which only the takeover section serving to take over the shingled stream S and the beginning of the active conveying run is shown in FIG. 1 .

Die Einrichtung 10 weist ein endlos im Sinne des Pfeiles 12' umlaufend angetriebenes Zugorgan 14 auf, das - wie sich noch zeigen wird - in einer Hohlschiene 15 und in Fig. 1 um ein nur schematisch angegebenes Umlenkrad 16 geführt ist. Das Zugorgan 14 ist mit in regelmässigen Abständen und seitlich an diesen befestigten Greifern 17 bestückt. Jeder dieser Greifer 17 weist eine bezüglich des Zugorganes 14 feste Backe 18 auf sowie eine bewegliche Backe 19, die - wie noch darzutun sein wird - in Offenstellung rechtwinklig zur festen Backe steht, im Zuge der Schliessbewegung aber zunächst unter die feste Backe 18 einschwenkbar und danach auf diese zustellbar ist (beides gegen die Wirkung einer Feder), sowie in Schliessstellung arretierbar ist. Der Fig. 1 ist zu entnehmen, dass die Klemmfläche jeder der festen Backen 18 im wesentlichen eine Ebene definiert. Diese Ebene ist in Fig. 1 links für zwei benachbarte, feste Backen mit gestrichelten Linien 20 angegeben, ist also gegenüber dem Zugorgan 14 je um den Winkel a geneigt.The device 10 has an endlessly driven traction element 14 in the direction of the arrow 12 ', which - as will be shown later - is guided in a hollow rail 15 and in FIG. 1 around a deflection wheel 16 which is only shown schematically. The traction element 14 is equipped with grippers 17 fastened at regular intervals and laterally to these. Each of these grippers 17 has a jaw 18 which is fixed with respect to the pulling element 14 and a movable jaw 19 which, as will be shown later, is at right angles to the fixed jaw in the open position, but can first be pivoted in under the fixed jaw 18 in the course of the closing movement and then it can be adjusted (both against the action of a spring) and can be locked in the closed position. It can be seen from FIG. 1 that the clamping surface of each of the fixed jaws 18 essentially defines a plane. This level is indicated on the left in FIG. 1 for two adjacent, fixed jaws with dashed lines 20 ben, is thus inclined relative to the tension member 14 by the angle a.

Die festen Backen 18 aller Greifer 17 sind untereinander durch ein flexibles Band 21 verbunden, das an der Klemmfläche der festen Backe 18 jedes Greifers 17 befestigt ist.The fixed jaws 18 of all grippers 17 are connected to one another by a flexible band 21 which is fastened to the clamping surface of the fixed jaw 18 of each gripper 17.

Dadurch wird der auf dem Förderband 11 anfallende und seitlich über dieses vorstehende Schuppenstrom S (Fig. 2) von oben gewissermassen durch ein «gewelltes Förderband» beaufschlagt, wobei die beweglichen Backen 19, nach ihrem Einschwenken und Zustellen auf die zugeordnete feste Backe 18, den Schuppenstrom S von unten her an dieses «gewellte Förderband» andrücken und zwar in diesem Beispiel jeweils nur am nachlaufenden Rücken jeder Welle.As a result, the accumulating stream S on the conveyor belt 11 and laterally projecting above this shingled stream S (FIG. 2) is acted upon from above by a “corrugated conveyor belt”, the movable jaws 19, after they have been swung in and delivered to the associated fixed jaw 18 Press scale stream S from below onto this “corrugated conveyor belt”, in this example only on the trailing back of each shaft.

Es wird nun zusätzlich auf Fig. 3 Bezug genommen. Man erkennt das den Schuppenstrom S heranführende Förderband 11, einen der Greifer 17 mit seiner festen Backe 18, dem daran befestigten flexiblen Band 21 und der bereits in Schliessstellung befindlichen beweglichen Backe 19. Die Hohlschiene 15 ist ein C-förmiges, nach unten offenes Profil, das in seinem Innern das Zugorgan 14 beherbergt. Dieses besteht aus einer Gliederkette 22, bei der der Gelenkzapfen 23 zwischen zwei aneinanderangelenkten Gliedern nach beiden Seiten verlängert ist und an beiden Enden je eine Laufrolle 24 trägt. In einem an jedem Kettenglied befestigten und sich aus der Hohlschiene 15 heraus erstreckenden Halterungsblock 25 ist mittels einer Klemmschraube 28 ein nach der Seite abstehender Ausleger 27 festgeklemmt, der mit seinem Ende im Gehäuse 29 des Greifers 17 verankert ist. Der Halterungsblock 25 verdeckt in Fig. 3 teilweise eine Führungsrolle 26, die drehbar auf einer rechtwinklig zum Zapfen 23 stehenden und strichpunktiert angedeuteten Achse 30 gelagert ist. Die Führungsrolle 26 wirkt namentlich bei gekrümmtem Verlauf der Hohlschiene 15 mit den einander zugekehrten Kanten der Schenkel 31 der Hohlschiene 15 zusammen.Reference is now made additionally to FIG. 3. One recognizes the conveyor belt 11 leading the scale stream S, one of the grippers 17 with its fixed jaw 18, the flexible belt 21 attached to it and the movable jaw 19 already in the closed position. The hollow rail 15 is a C-shaped profile which is open at the bottom, which houses the traction element 14 inside. This consists of a link chain 22, in which the pivot pin 23 is extended between two hinged links on both sides and carries a roller 24 at each end. In a mounting block 25 fastened to each chain link and extending out of the hollow rail 15, a bracket 27 projecting to the side is clamped by means of a clamping screw 28 and its end is anchored in the housing 29 of the gripper 17. In FIG. 3, the mounting block 25 partially hides a guide roller 26 which is rotatably mounted on an axis 30 which is perpendicular to the pin 23 and is indicated by dash-dotted lines. The guide roller 26 cooperates with the curved edges of the legs 31 of the hollow rail 15, particularly when the hollow rail 15 is curved.

Der Aufbau der Greifer ist nachstehend an Hand der Fig. 3 und 4 beschrieben. Die feste Backe 18 ist einstückig am Gehäuse 29 angeformt. Die bewegliche Backe 19 dagegen ist über einen Klemmring 37 drehfest an einem Schaft 32 verankert, der rechtwinklig zu der von der festen Backe 18 definierten Ebene angeordnet ist und sowohl längsverschiebbar als auch drehbar gegen die Wirkung einer Feder 33 im Gehäuse 29 gelagert ist. Die Feder 33 hat das Bestreben, die bewegliche Backe 19 in der aus Fig. 4 links ersichtlichen Stellung zu halten.The structure of the gripper is described below with reference to FIGS. 3 and 4. The fixed jaw 18 is integrally formed on the housing 29. The movable jaw 19, on the other hand, is anchored in a rotationally fixed manner to a shaft 32 via a clamping ring 37, which is arranged at right angles to the plane defined by the fixed jaw 18 and is mounted both longitudinally displaceably and rotatably against the action of a spring 33 in the housing 29. The spring 33 tends to keep the movable jaw 19 in the position shown in FIG. 4 on the left.

Am Gehäuse 29 ist ausserdem ein Klemmriegel 34 angelenkt, der eine Bohrung 35 (Fig. 3) aufweist, durch die sich der Schaft 32 erstreckt. Der Klemmriegel 34 steht unter der Wirkung einer Druckfeder 36 (Fig. 3), die das Bestreben hat, den Klemmriegel nach unten (d.h. in Fig. 4 im Gegenuhrzeigersinn) verschwenkt zu halten. Durch diese Anordnung lässt sich der Schaft 32 ohne weiteres verdrehen und auch ohne weiteres von der in Fig. 4 links gezeigten Stellung nach oben verschieben, bleibt aber in der nach oben verschobenen Lage arretiert. Der Klemmriegel 34 wirkt mit anderen Worten gewissermassen als « Freilauf» für die Längsverschiebung des Schaftes 32, welcher Freilauf durch Anheben des Klemmriegels 34 freigebbar ist.A clamp bolt 34 is also articulated on the housing 29 and has a bore 35 (FIG. 3) through which the shaft 32 extends. The clamp bolt 34 is under the action of a compression spring 36 (Fig. 3) which tends to keep the clamp bolt pivoted downward (i.e. counterclockwise in Fig. 4). This arrangement allows the shaft 32 to be easily rotated and also easily moved upward from the position shown on the left in FIG. 4, but remains locked in the upwardly displaced position. In other words, the clamping bolt 34 acts as a kind of “freewheel” for the longitudinal displacement of the shaft 32, which freewheel can be released by lifting the clamping bolt 34.

Insbesondere den Fig. 2, 3 und 4 lässt sich entnehmen, dass am Schaft 32 unmittelbar oberhalb des die bewegliche Backe 19 am Schaft 32 verankernden Klemmrings 37 ein weiterer Block 38 verankert ist. Dieser Block 38 trägt zwei Folgeglieder, von denen das eine eine Nase 39 (Fig. 2) ist, das andere eine am Block 38 drehbar gelagerte Rolle 40. Der Fig. 2 lässt sich weiter entnehmen, dass die Nase 39 mit der Seitenkante 41 einer Kulisse 42 zusammenwirkt und beim Auflaufen auf diese Seitenkante 41 eine Verdrehung des Schaftes 32 im Gegenuhrzeigersinn (in Fig. 2) gegen die Wirkung der Feder 33 bewirkt. Die Rolle 40 dagegen wirkt mit der oberen, flachen Seite 43 (Fig. 3) der Kulisse 42 zusammen, die - wie in Fig. 4 gestrichelt angetönt - eine ansteigende Rampe bildet. Dadurch wird der Schaft 42 und damit die bewegliche Backe 19 nach der von der Nase 39 mit der Seitenkante 41 bewirkten Drehbewegung angehoben, d.h. auf die feste Backe 18 hinzugestellt. In dieser Stellung bleibt die bewegliche Backe durch den Klemmriegel 34 arretiert. Damit klemmt die Backe 19 den Schuppenstrom S von unten her an das flexible Band 21, welches durch die Neigung der Klemmflächen der Backen 18 eine Wellenform aufweist.2, 3 and 4 in particular that a further block 38 is anchored to the shaft 32 directly above the clamping ring 37 anchoring the movable jaw 19 to the shaft 32. This block 38 carries two follower links, one of which is a nose 39 (FIG. 2), the other a roller 40 rotatably mounted on the block 38. FIG. 2 further shows that the nose 39 with the side edge 41 is one Backdrop 42 cooperates and, when running onto this side edge 41, causes shaft 32 to rotate in the counterclockwise direction (in FIG. 2) against the action of spring 33. The roller 40, on the other hand, interacts with the upper, flat side 43 (FIG. 3) of the link 42, which - as indicated by dashed lines in FIG. 4 - forms an ascending ramp. As a result, the shaft 42 and thus the movable jaw 19 is raised after the rotary movement caused by the nose 39 with the side edge 41, i.e. added to the fixed jaw 18. In this position, the movable jaw remains locked by the clamp bolt 34. Thus, the jaw 19 clamps the shingled stream S from below onto the flexible band 21, which has a wave shape due to the inclination of the clamping surfaces of the jaws 18.

Damit die Kulisse 42 von einer wirksamen Stellung, d.h. von einer die Greifer in Schliessrichtung betätigenden Stellung in eine Ruhestellung gebracht werden kann, d.h. wenn vom Förderband 11 keine Papierprodukte aufzunehmen sind, ist die Kulisse 42 an einem schwenkbaren Blech 44 befestigt, das mittels eines Betätigungselementes, z. B. mittels eines Pneumatikzylinders 45 (Fig. 1) von der wirksamen Stellung in Ruhestellung zurückverschwenkt werden kann.So that the backdrop 42 of an effective position, i.e. can be brought into a rest position from a position actuating the grippers in the closing direction, i.e. if no paper products are to be picked up from the conveyor belt 11, the link 42 is fastened to a pivotable plate 44 which is actuated by means of an actuating element, e.g. B. by means of a pneumatic cylinder 45 (Fig. 1) can be pivoted back from the active position in the rest position.

Eine oder mehrere nicht dargestellte Abgabestationen der Einrichtung können sich entlang des förderaktiven Trums des Zugorganes befinden oder im Bereich eines weiteren Umlenkrades, auf welches das förderaktive Trum aufläuft. An einer solchen Abgabestation braucht es neben einer die geförderten Druckprodukte aufnehmenden Vorrichtung z. B. einem Stapelschacht oder einem Förderband, lediglich eine mit den Klemmriegeln 34 in dem Sinne zusammenwirkendes Organ, beispielsweise eine Kulisse oder eine Rolle, dass der Klemmriegel 34 gegen die Wirkung der Druckfeder 36 verschwenkt wird, worauf die bewegliche Backe 19 schlagartig von der in Fig. 4 rechts in die in Fig. 4 links dargestellte Stellung zurückschnellt. Damit ist der geförderte Schuppenstrom freigegeben.One or more delivery stations (not shown) of the device can be located along the conveying strand of the traction element or in the region of a further deflection wheel onto which the conveying strand runs. At such a delivery station, in addition to a device receiving the conveyed printed products, e.g. B. a stacking shaft or a conveyor belt, only one with the clamping bars 34 cooperating in the sense organ, for example a backdrop or a role that the clamping bar 34 is pivoted against the action of the compression spring 36, whereupon the movable jaw 19 abruptly from that in Fig 4 jumps back to the position shown on the left in FIG. This means that the shed flow is released.
