To that end, the gripper chain drive wheel and the bucket wheels have a common axis of rotation but are driven separately from one another.

Description

Beschrei bungDescription
Einrichtung zur Übergabe von DruckproduktenDevice for the delivery of printed products
Die Erfindung betrifft eine Einrichtung zur Übergabe von Druckprodukten entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a device for transferring printed products according to the preamble of claim 1.
Durch die CH-PS 4 27 625 ist eine Einrichtung bekannt geworden, mit welcher die Druckprodukte mittels einer mit Greifern ausgestatteten Kette zwangsläufig aus den Schaufelrädern herausgeführt werden. Dabei sind mehrere Schaufelräder sowie ein Kettenrad auf einer gemeinsamen Welle befestigt und weisen also die gleiche Drehzahl auf .CH-PS 4 27 625 has disclosed a device with which the printed products are inevitably guided out of the paddle wheels by means of a chain equipped with grippers. Several paddle wheels and a chain wheel are attached to a common shaft and therefore have the same speed.
Kurz nach Übernahme der Druckprodukten durch die Greifer werden die Sc häuf e l radt as chen aus dem Bereich des von den Greifern gehaltenen Druckprodukten herausgedreht. Nachteilig dabei ist, daß der im Greifermaul befindliche Teil des Druckproduktes beim Herausdrehen aus dem Grund der Schaufe l radt as ehe beschädigt werden kann. Dies trifft insbesondere bei dickeren D rυc kprodukten zu.Shortly after the grippers take over the printed products, the scooter wheels are turned out of the area of the printed products held by the grippers. The disadvantage here is that the part of the printed product located in the gripper's mouth can be damaged as soon as it is unscrewed from the bottom of the bucket. This is especially true for thicker print products.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur Übergabe von Druckprodukten aus einem Schaufelrad zu schaffen.The invention has for its object to provide a device for transferring printed products from a paddle wheel.
Diese Aufgabe wird er indungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.According to the description, this task is achieved through the characteristics of the characterizing part of claim 1 solved.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß sich der Grund einer Schauf e l radtasche nach Übergabe eines Druckproduktes an einen Greifer von der Vorderkante des Druckproduktes entfernt, bevor sich die Schauf e l radtasche aus dem Bereich des Druckproduktes herausdreht. Somit ist bei einer kompakten und einfachen Bauweise des Schaufelrad- und Kettenantriebes ein beschädigungsfreies Entnehmen des Druckproduktes aus den Schaufelrädern und Übernahme von einen Kettenförderer gewährleistet.The advantages that can be achieved with the invention are, in particular, that the bottom of a Schauf e l pannier is removed from the front edge of the printed product after transfer of a printed product to a gripper before the Schauf e l pannier rotates out of the area of the printed product. Thus, with a compact and simple construction of the paddle wheel and chain drive, damage-free removal of the printed product from the paddle wheels and takeover by a chain conveyor is guaranteed.

Die Funktion der Einrichtung ist wie nachfolgend beschrieben. Vom Bandsystem 1 des Falzapparates kommende, vorzugsweise gefalzte Druckprodukte 6 gelangen an einem Einlaufort A des im Gegenuhrzeigersinn laufenden Schaufelrades 2 bis 5 bis zum Grund 62 der Schauf e l radtas ehe 61. An diesem Einlaufort A befindet sich gleichzeitig ein geöffnetes Greifermaul 31 eines Greifers 17 in einer solchen Position, in welcher der Grund 63 des Gre i fe rmau les 31 in einer zur Welle 9 achsparallelen Stellung befindlich ist. Dadurch erhalten die Falzkanten insbesondere von dicken Falzprodukten, z. B. von vier Millimetern, eine gleichmäßige Auf Lage f lache . Nach erfolgtem Einlauf des Druckproduktes 6 in die Schauf e l radt asche 61 bzw. des Gre i fe rmau les 61 fährt der die Rolle 23 tragende zweite Hebel 22 gegen die gestellfeste Steuerkurve 24. Dadurch wird die schwenkbare Klemmbacke 19 gegen das Druckprodukt 6 gedrückt. Das Druckprodukt 6 ist somit im Greifermaul 31 f es tgek lemmt .The function of the device is as described below. Compressed, preferably folded, printed products 6 coming from the belt system 1 of the folding apparatus arrive at an entry point A of the paddle wheel 2 to 5 running counterclockwise up to the bottom 62 of the bucket el radtas before 61. At this entry point A there is at the same time an open gripper mouth 31 of a gripper 17 in such a position in which the bottom 63 of the Gre i fe rmau les 31 is in a position axially parallel to the shaft 9. This gives the folded edges especially of thick folded products, e.g. B. of four millimeters, a uniform On location f flat. After the printed product 6 has entered the paddle wheel 61 or the Grei fe rmau les 61, the second lever 22 carrying the roller 23 moves against the control curve 24 fixed to the frame. As a result, the pivotable clamping jaw 19 is pressed against the printed product 6. The printed product 6 is thus clamped in the gripper mouth 31.
Infolge der höheren Drehzahl und somit auch der größeren Umfangsgeschwindigkeit der Schaufelräder 2 bis 5 entfernt sich der Grund 62 der Schauf e l radtas ehe 61 vom Grund 63 des Gre i fe rmau les 31. Somit erfolgt an einer Trennstelle B der Bewegungs r i cht ung der Greiferkette 14 und der Schauf e l radt as chen 61 eine solche Bewegung der Schauf e l radtas chen 61, die eine Beschädigung der Vorderkante des Druckproduktes 6 ausschließt.As a result of the higher rotational speed and thus also the greater peripheral speed of the paddle wheels 2 to 5, the base 62 of the paddle wheels 61 moves away from the base 63 of the gripper arm 31. Thus, the movement direction of the gripper chain takes place at a separation point B. 14 and the Schauf el radtas chen 61 such a movement of the Schauf el radtas chen 61, which excludes damage to the front edge of the printed product 6.
Die Verstellung des Einlaufortes A kann durch Verdrehen des Antriebsrades 12 erfolgen. Infolge der Übersetzung zwischen den Zahnrädern 46, 51 bzw. 44, 49 entsteht dabei eine Differenz zwischen dem Grund 62 der Schauf e l radtas c he 61 und dem Grund 63 des Grei fe rmau les 31. Diese Differenz kann dadurch ausgeglichen werden, daß die Welle 53 mit dem Zahnrad 47 bzw. die Welle 52 mit dem Zahnrad 47 jeweils gegen ein Differentialgetriebe ausgetauscht wird. Ein solches Getriebe kann als Ha r oni c-D r i ve- oder als Verschiebegetriebe ausgebildet sein. Das Zugmittel 14 kann verschiedenartig ausgeführt sein: z. B. als Kette, Zahnriemen oder als Flachriemen mit Antriebsöffnungen im regelmäßigen Abstand. Die Erfindung ist nicht auf die Anordnung von Schaufelrädern 2 bis 5 auf Buchsen 42, 43, die auf der Antriebswelle 9 für das Zugmittelantriebsrad 11,- z. B. ein Kettenrad -, sind, beschränkt. Vielmehr kann auch das Zugmittelantriebsrad 11 auf einer Buchse 42 plus 43 auf der sämtliche Schau elräder 2 bis 5 gelagert sind, dreh- und antreibbar angeordnet sein. The entry point A can be adjusted by turning the drive wheel 12. As a result of the translation between the gears 46, 51 and 44, 49, there is a difference between the bottom 62 of the bucket el radtas c he 61 and the bottom 63 of the Grei fe rmau les 31. This difference can be compensated for by the fact that the shaft 53 with the gear 47 or the shaft 52 with the gear 47 is exchanged for a differential gear. Such a gearbox can be designed as a Ha r oni cD ri ve or as a sliding gear. The traction means 14 can be designed in various ways: z. B. as a chain, toothed belt or as a flat belt with drive openings at regular intervals. The invention is not based on the arrangement of paddle wheels 2 to 5 on bushings 42, 43, which on the drive shaft 9 for the traction drive wheel 11, -. B. a sprocket - are limited. Rather, the traction drive wheel 11 can be rotatably and drivably arranged on a bushing 42 plus 43 on which all the display wheels 2 to 5 are mounted.
