Die nach der aufgeführten Druckschrift vorgeschlagene Einrichtungen
verfügt nicht über die Vorkehrungen, die einer störungsfreien
Verarbeitung der in unterschiedlichen Formaten und
Dicken vorkommenden Gegenstände genügen.
Es mangelt der bekannten Einrichtung nicht nur an einem zuverlässigen
Funktionieren der zusammenhängenden Bewegungen an
der Erfassungsstelle der Gegenstände, sondern auch im Bereich
der Übergabe von der Vereinzelungsstation zum Weitertransport.The facilities proposed according to the listed publication do not have the precautions which are sufficient for trouble-free processing of the objects occurring in different formats and thicknesses.
The known device lacks not only a reliable functioning of the coherent movements at the detection point of the objects, but also in the area of the transfer from the separating station to further transport.
Aufgabe der vorliegenden Erfindung ist es deshalb, eine Einrichtung der eingangs genannten Art zu schaffen, bei der die Zuverlässigkeit der Verarbeitung und damit die Leistung auf einfache Weise verbessert werden kann.The object of the present invention is therefore a device to create the type mentioned, in which the Reliability of processing and therefore performance can be easily improved.
Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass die
Fördervorrichtung an einer Führungsanordnung etwa parallel zu
der Stapelbildungsrichtung gegen das vordere Stapelende hubartig
zustellbar angetrieben ist.
Eine solche Ausbildung gestattet eine kontinuierliche Verarbeitung
von flachen Gegenständen unterschiedlicher Grösse.According to the invention, this object is achieved in that the conveyor device is driven on a guide arrangement in a stroke-like manner against the front end of the stack, approximately parallel to the stack formation direction.
Such training allows continuous processing of flat objects of different sizes.
Vorteilhaft ist der maximale Zustellhub der Fördervorrichtung durch Anschläge begrenzt, sodass die Abgabesposition der Gegenstände veränderbar ist.The maximum feed stroke of the conveyor device is advantageous limited by stops, so that the delivery position of the objects is changeable.
Vorzugsweise ist die Fördervorrichtung an einem antreibbaren Gestell befestigt, das sich als Teil der Führungsanordnung ausbilden lässt. The conveying device is preferably drivable Frame attached, which is part of the guide assembly can be trained.
Das Gestell erweist sich auch als verbindender Bauteil zu einer die Antriebskraft erzeugenden Last als zweckmässig.The frame also proves to be a connecting component to one the driving force generating load as appropriate.
Zur Begünstigung des Vereinzelungsvorganges ist dem bandförmigen Förderorgan eine mit letzterem einen Einzugsspalt für die erfassten Gegenstände bildende gleichsinnig drehbare Abstreifrolle zugeordnet, die auch einer Stabilisierung der Gegenstände während dem Vereinzelungsvorgang zuträglich ist.To favor the separation process is the band-shaped Funding body one with the latter a feed gap for the Scrapped roller forming objects in the same direction assigned which also stabilize the objects is beneficial during the separation process.
Der Abstreifrolle, die durch die Gegenstände angetrieben wird, ist an dem Zutrittsende des Einzugsspaltes auf der von dem Förderorgan abgewendeten Seite ein stationäres Leitorgan vorgeschaltet, das den Einzugsvorgang der Gegenstände unterstützt.The scraper roller that is driven by the objects is at the entry end of the feed gap on the of the A stationary guide element is connected upstream from the side facing away from the that supports the feeding process of the objects.
Dieses Leitorgan kann auch gegenüber der Abstreifrolle zur Veränderung des Einzugsspaltes verstellbar ausgebildet sein.This guide can also be compared to the scraper Change in the feed gap to be adjustable.
Deshalb ist die Abstreifrolle und/oder das Leitorgan zum Förderorgan hin und von diesem weg versetzbar und/oder der Einzugswinkel veränderbar ausgebildet, sodass der Einzugsspalt an die Einzugsbedingungen angepasst werden können.That is why the scraper roller and / or the guide element for the conveyor element can be moved to and from this and / or the feed angle designed to be changeable so that the feed gap the collection conditions can be adjusted.
Die Zustellbewegung der Abstreifrolle und/oder das Leitorgan erfolgt vorteilhaft mit Hilfe eines Kraftspeichers gegen den die genannten Organe durch das Auftreffen eines vom Stapel abgezogenen Gegenstandes zurückweichen.The feed movement of the scraper roller and / or the guide element is advantageously carried out with the help of an energy store against the said organs by hitting one of the piles withdraw the removed object.
Die Bewegungsrichtung der Abstreifrolle zum Förderorgan ist zweckmässig so gewählt, dass sie mit letzterem bzw. dem Trum des Förderorgans einen spitzen Winkel einschliesst, wodurch die durch das Auftreffen der Gegenstände erzeugten Schläge gemildert werden. The direction of movement of the scraper roller to the conveyor is appropriately chosen so that it with the latter or the strand of the conveyor element encloses an acute angle, whereby the blows caused by the impact of the objects be mitigated.
Zur Erzielung der Anstellbewegung - in deren einen Endposition die Abstreifrolle wenigstens annähernd an dem Förderorgan ansteht - ist vorteilhaft eine Linearführung bzw. Längsführung vorgesehen, welche leicht und genau reagiert.To achieve the positioning movement - in one end position the scraper roller is at least approximately on the conveyor - A linear guide or longitudinal guide is advantageous provided which reacts easily and accurately.
Hierzu ist die Linearführung durch zwei an einem Support voneinander beabstandete parallele Führungselemente ausgebildet, an denen ein die gelagerten Abstreifrollen aufnehmender Lagerbock verschiebbar angeordnet ist.For this purpose, the linear guide is supported by two at one support spaced parallel guide elements formed, on which a bearing block receiving the stripper rollers is slidably arranged.
Die Anstellkraft der Abstreifrolle gegen das Förderorgan kann dadurch erreicht werden, dass der Kraftspeicher zwischen Support und Lagerbock vorgesehen wird, beispielsweise durch eine Druckfeder.The contact force of the scraper roller against the conveyor can can be achieved in that the lift mechanism between support and bearing block is provided, for example by a Compression spring.
Eine weitgehend störungsfreie Vereinzelung der in einem Stapel transportierten Gegenstände kann dann erzielt werden, wenn das Transportmittel zur Bestimmung der Zuführgeschwindigkeit der Gegenstände in Abhängigkeit zur Hublage der Fördervorrichtung bzw. des Förderorgans mit einer Steuervorrichtung verbunden ist, sodass ein automatischer Regeleffekt bei der Stapelverarbeitung eintritt.A largely trouble-free separation of the in a stack transported objects can be achieved if that Means of transport for determining the feed speed of the Objects depending on the stroke position of the conveyor or the conveyor member connected to a control device is, so that an automatic control effect in batch processing entry.
Um der Fördervorrichtung ununterbrochen flache Gegenstände zuführung zu können, ist es zweckmässig, wenn das durch ein oder mehrere Transportbänder ausgebildete Transportmittel mit in Abständen sich folgenden, quer zur Transportrichtung angeordneten, gegenseitig Einsteckfächer bildenden Mitnehmern ausgebildet ist, die im Wirkbereich des zu passierenden Förderorgans eine Ausnehmung aufweisen, wobei die Ausnehmung jeweils oberhalb des Förderorgans endet.Flat objects continuously around the conveyor to be able to feed, it is appropriate if this through a or several conveyor belts with trained means of transport at intervals, arranged transversely to the direction of transport, mutually inserting slots is formed in the effective area of the conveyor to be passed have a recess, the recess in each case ends above the funding body.
Es empfiehlt sich zudem, dass die durch die Mitnehmer gebildeten Transportfächer durch eine vor dem Förderorgan endende, eine konstante Anschlagkante für die Gegenstände bildende stationäre Wand einseitig geschlossen sind, sodass die abzutragenden Gegenstände jeweils an der gleichen Stelle des Förderorgans auftreffen.It is also recommended that those formed by the carriers Transport compartments through an end in front of the funding body a constant stop edge for stationary objects forming objects Wall are closed on one side, so that to be removed Objects in the same place on the funding body hit.
