Vorrichtung zum Abziehen einzelner flächenhafter
Gegenstände von einem StapelDevice for pulling off individual planar
Items from a pile
Die vorliegende Erfindung betrifft eine Vorrichtung
zum Abziehen einzelner flächenhafter Gegenstände von einem
Stapel. Derartige Gegenstände sind z.B. Blätter, Couvert '
oder Kartons. -The present invention relates to a device for peeling off individual flat objects from one
Stack. Such objects are e.g. sheets, envelopes
or cardboard boxes. -
Es sind verschiedene Vorrichtungen zum Abziehen von flächenhaften Gegenständen bekannt, wobei zum Abzug des jeweils untersten Gegenstandes des Stapels entweder pneumatisch arbeitende Vorrichtungen, die den untersten Gegenstand ansaugen, oder die Gegenstände durch Reibungskräfte fortbewegende Elemente wie Bänder usw., verwendet werden. Dabei kommt es oft vor, dass gleichzeitig mehrere Gegenstände mitgenommen v/erden, oder dass Gegenstände mit unregelmässiger Oberfläche hängen bleiben. Das sind unangenehme Erscheinungen, die den Arbeitsablauf erheblich verzögern, und den Abbau des Stapels nachteilig beeinflussen.Various devices are known for peeling off flat objects, whereby either pneumatically operated devices that suck in the bottom object or elements such as belts, etc. that move the objects by frictional forces are used to pull off the bottom object in each case. It often happens that several objects are taken along at the same time, or that objects with an irregular surface get stuck. These are unpleasant phenomena that considerably delay the workflow and have an adverse effect on the dismantling of the pile.
Ziel der Erfindung ist es, diese Nachteile zu eliminie.-ren. The aim of the invention is to eliminate these disadvantages.

Dieses Ziel wird erfindungsgemäss dadurch erreicht, dass mindestens zwei Förderrollen vorhanden sind,- um 5eweils den untersten der flächenhaften Gegenstände vom Stapel abzuziehen und zu transportierenj und dass zwischen den genannten Förderrollen ein Lineal, das als Anschlag für den Stapel dient, quer zur Förderebene der flächenhaften Gegenstände angeordnet ist, und mit dem einen Ende diese Förderebene durchstösst um den am Lineal vorbeibewegten flächenhaften Gegenstand auszubiegen.This object is achieved according to the invention in that at least two conveying rollers are provided, - by 5 ewe ils withdraw the lowermost one of the sheet items from the stack and to transportierenj and that between said conveyor rollers, a ruler, which serves as a stop for the stack, transversely to the conveying plane the planar objects is arranged, and with one end penetrates this conveying plane in order to bend out the planar object moved past the ruler.
Nachfolgend wird ein Ausführungsbeispiel des Erfindungsgegenstandes anhand der Zeichnung näher beschrieben» Es zeigen:An exemplary embodiment of the subject matter of the invention is described in more detail below with reference to the drawing demonstrate:
Fig. 1 eine Frontansicht und
Fig. 2 eine Seitenansicht einer Vorrichtung zum Abziehen einzelner flächenhaXter Gegenstände.Fig. 1 is a front view and
Fig. 2 is a side view of a device for pulling off individual surface-mounted objects.
Die Figuren zeigen eine Anordnung mit mehreren Rollenpaaren, wobei zwischen je zwei Rollen 4 ein Lineal. 3 angeordnet ist.The figures show an arrangement with several pairs of rollers, with a ruler between each two rollers 4. 3 arranged is.
Aus der Figur 2 geht hervor, dass auf einem Auflagetisch 2 ein Stapel 1, bestehend aus flächenhaften Gegenständen aufgebaut'ist," welcher im Anstellwinkel aC beliebig verstellbar ist. Die Lineale 3 dienen als Anschläge für den Stapel 1. Der unterste Abschnitt 3a der Lineale 3 ist in För-derr-ichtung abgewinkelt und dessen unteres Ende 3b ist bombiert. Die bombierten Förderrollen *f sind unterhalb des Stapels 1 angeordnet, und sind mit einem Belag, einem sogenannten Friktionssegment 5, versehen.It can be seen from FIG. 2 that a stack 1, consisting of flat objects, is built up on a support table 2 and is freely adjustable in the angle of incidence aC . The rulers 3 serve as stops for the stack 1. The lowermost section 3a of the rulers 3 is angled in the conveying direction and its lower end 3b is cambered. The cambered conveyor rollers * f are arranged below the stack 1 and are provided with a covering, a so-called friction segment 5.
Zur Weiterförderung der flächenhaften Gegenstände ist eine Abzugswelle 8 und eine Abzugsrolle 7 angeordnet. Die Funkt ionsvjeise der erfindungsgeisässen Vorrichtung geht folgendermassen vor sich:A take-off shaft 8 and a take-off roller 7 are arranged for the further conveyance of the flat objects. the The function of the device according to the invention is as follows in front of you:
Der Stapel wird von unten her durch einzelnes Abziehen der flächenhaften Gegenstände abgebaut, und in einer Förder-The stack is broken down from below by pulling off the flat objects individually, and in a conveyor
