Abstract

The lowest sheet from a stack (1) or curved paper sheets is removed by a rotor assembly. The rotor has equally spaced sets of axial rollers (7) for the support of the paper stack (1). Suction cylinders (4) of larger diameter are located between the support rollers (7) and together they produce a continuous cylindrical outside surface. As the vacuum grooves (5) on the cylinder (4) attracts the leading edge of the paper sheet (14), the cylinder (4) is being rotated by the friction that is produced by the paper stack. Since the cylinder rotates in the opposite direction from the main rotor, the lowest paper sheet is being peeled away from the stack (1).

Description

1515th

Die Erfindung betrifft eine Abv.älzunterlage für gewölbte Stapel, bestehend aus runden, zur Wölbachse achsparallelen Trag-Vereinzelungskörpern und/oder Tragkörpern, insbesondere für Falzbogenanleger.The invention relates to a Abv.älzunterlage for Arched stacks, consisting of round, axially parallel to the arching axis support separating bodies and / or Support bodies, in particular for folded sheet feeders.

Es sind Falzbogenanleger bekannt, die die Bogenvereinzelung von der Unterseite eines gewölbten Stapels vornehmen. Dieser Stapel ist auf, unter demselben sich abwälzenden, runden, zur Wölbachse achsparallelen Trag-Vereinzelungskörpern und/oder reinen Tragkörpern gelagert Die Trag-Vereinzelungskörper bestehen hierbei zumeist aus auf Wellen gelagerten, mit Saugern versehenen Scheiben und die Tragkörper aus ebenfalls auf Wellen gelagerten Rollen. Die Trag-Vereinzelungskörper in Verbindung mit den Tragkörpern ermöglichen durch planetenartigen Ablauf ein reibungsfreies Vereinzeln des jeweils untersten Falzbogens.There are known folded sheet feeders that separate the sheets from the bottom of a curved pile. This pile is on top of, under the same itself rolling, round supporting-separating bodies axially parallel to the curved axis and / or pure supporting bodies stored The support-separating bodies mostly consist of shafts with suction cups provided disks and the support body from rollers also mounted on shafts. The support separating body In connection with the supporting bodies, a planet-like process enables frictionless Separation of the lowest folded sheet in each case.

Beim Abwälzen der Trag-Vereinzelungskörper und der Tragkörper unter dem Bogenstapel entsteht jedoch zu letzterem ein Walkeffekt Dieser wirkt sich derart nachteilig aus, daß die unteren Falzbogen des Stapels sich in Transportrichtung der Tragkörper, d. h. entgegen deren Drehrichtung, fächerartig verschieben. Die Folge hiervon ist eine erschwerte Bogenvereinzeiung, die bis zu Störungen im Vereinzelungsablauf führen kann.However, when rolling the support-separating body and the support body under the sheet pile arises to the latter a flexing effect This has such a disadvantage that the lower folded sheets of the stack in the transport direction of the support body, d. H. in the opposite direction of rotation, move like a fan. The consequence of this is a more difficult arch singulation, which up to can lead to disruptions in the separation process.

Der Erfindung liegt die Aufgabe zugrunde, eine mit Trag-Vereinzelungskörpern und/oder Tragkörpern ausgerüstete Abwälzunterlage für gewölbte Stapel so zu gestalten, daß die Walkwirksamkeit auf ein Minimum gemindert und damit ein störungsfreies Vereinzeln der Falzbogen ermöglicht wird.The invention is based on the object of a equipped with support separating bodies and / or support bodies Rolling pad for curved stacks to be designed so that the flexing efficiency is reduced to a minimum reduced and thus a trouble-free separation of the folded sheets is made possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Trag-Vereinzelungskörper und/oder die Tragkörper achsparallele nutenförmige Aussparungen aufweisen.This object is achieved according to the invention in that the support-separating body and / or the Have support body axially parallel groove-shaped recesses.

Die Erfindung wird nachstehend an einem Ausführungsbeispiel näher erläutert Die Zeichnung zeigt einen Falzbogenanleger in Seitenansicht, mit achsparallel zu den Trag-Vereinzelungskörpern nutförmig verlaufenden Aussparungen.The invention is explained in more detail below using an exemplary embodiment. The drawing shows a Folded sheet feeder in side view, with axially parallel to the support separating bodies Recesses.

Unterhalb eines gewölbten, aus Falzbogen bestehenden Stapels 1 sind kreisförmig um eine Welle 2 herum, in einem Gestell 3, Trag-Vereinzelungskörper 4 und scheibenförmige Tragkörper 7 gelagert Die Trag-Vereinzelungskörper 4 sind an ihrer Oberfläche, parallel zu ihrer Achse, mit nutförmigen Aussparungen 5 versehen; zwischen diesen verbleiben Stege 6.Below a curved stack 1 consisting of folded sheets are circularly around a shaft 2, in a frame 3, supporting separating body 4 and disk-shaped supporting body 7 mounted The supporting separating body 4 are provided with groove-shaped recesses 5 on their surface, parallel to their axis; webs 6 remain between these.

Die Weile 2 dreht sich mit dem Gestell 3 entgegen dem Uhrzeigersinn. Die Trag-Vereinzelungskörper 4 und die Tragkörper 7 drehen sich im Gestell 3 im Uhrzeigersinn. Die Trag-Vereinzelungskörper 4 erfassen hierbei mittels nicht gezeichneter Vereinzelungsmittel, beispielsweise Saugdüsen oder Greifer, den jeweils untersten Falzbogen 14 und wälzen diesen, durch die gegenläufige Umdrehung des Gestelles 3 und der Trag- Vereinzelungskörper 4 bzw. der Tragkörper 7, von der Unterseite des gewölbten Stapels t ab. Da der Stapel t hierbei nur auf den zwischen den nutförmigen Aussparungen 5 verbleibenden Stegen 6 der Trag-Vereinzelungskörper 4 aufliegt ist die Walkwirksamkeit auf ein Minimum verringert Der Stapel 1 hält somit an der Unterseite seine Form nahezu ein, so daß ein störungsfreies Vereinzeln der Falzbogen gewährleistet istThe while 2 rotates with the frame 3 counterclockwise. The support separating bodies 4 and the supporting bodies 7 rotate clockwise in the frame 3. The support separating body 4 grasp in this case by means of separating means not shown, For example, suction nozzles or grippers, each of the lowermost folded sheets 14 and roll them through the opposite rotation of the frame 3 and the support separating body 4 or the support body 7, from the bottom of the domed stack t. Since the stack t here only on the between the groove-shaped Recesses 5 remaining webs 6 of the support-separating body 4 rests on the flexing effectiveness reduced to a minimum The stack 1 thus almost maintains its shape on the underside, so that a trouble-free separation of the folded sheets is guaranteed
