Description

Die Erfindung bezieht sich auf einen Sauger, insbesondere einen Trennsauger zum Erfassen und Anheben des jeweils obersten Bogens von einem Bogenstapel, mit einem elastischen Faltenbalg, der durch Unterdruckbeaugschlagung seines Innenraumes aus seinem entspannten Zustand in einen Zustand geringerer Lange zusammenziehbar ist und der mit seinem oberen Ende an einem Saugerkörper befestigt ist, dessen dem Faltenbalg zugewandte Stirnseite einen Boden des Innenraums des Faltenbalgs bildet, sowie mit einer unterdruckbeaugschlagbaren Saugdüse, die Saugöffnungen aufweist, welche zu einer Saugflache der Saugdüse führen und an der Saugfläche nach außen münden.The invention relates to a sucker, in particular a vacuum cleaner to capture and lift each top sheet from a sheet stack, with one elastic bellows caused by negative pressure its interior from its relaxed state is contractible into a state of shorter length and that with its upper end on a sucker body is attached, the front side facing the bellows forms a bottom of the interior of the bellows, as well as with a suction nozzle that can be subjected to negative pressure, has the suction openings, which to a suction surface guide the suction nozzle and follow the suction surface flow outside.

Bei einem derartigen Sauger ist es bekannt, die Saugdüse als Einsatzbauteil auszubilden und an dem unteren Ende des Faltenbalgs durch Einknüpfen zu befestigen.In such a suction device, it is known to use the suction nozzle train as an insert component and on the lower one Attach the end of the bellows by tying it in.

Eine solche Ausbildung ist sowohl bauteil- als auch montageaufwendig. Darüberhinaus besteht die Gefahr einer Doppelbogenerfassung.Such training is both component and assembly-intensive. There is also the danger a double sheet detection.

Aufgabe der Erfindung ist es daher einen Sauger der eingangs genannten Art zu schaffen, der aus einer geringen Anzahl von Bauteilen besteht, leicht montierbar ist und bei Doppelbogenerfassung den zweiten Bogen abstößt.The object of the invention is therefore a sucker to create the kind mentioned at the outset from a minor Number of components, easy to assemble and repels the second sheet in double sheet detection.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Saugdüse am durch die Stirnseite des Saugerkörpers gebildeten Boden des Innenraums des Faltenbalgs angeordnet ist und die Saugöffnungen nach außen in den Innenraum des Faltenbalgs münden und daß der jeweils oberste Bogen von dem freien Ende des Faltenbalgs erfaßbar ist.This object is achieved in that the suction nozzle through the front of the suction body formed bottom of the interior of the bellows arranged and the suction openings to the outside into the interior of the bellows and that each uppermost sheet from the free end of the bellows is.

Das sich in den Innenraum Hineinwölben des erfaßten Bogens bewirkt bei Doppelbogenerfassung eine Relativbewegung der beiden erfaßten Bogen und somit ein Abstoßen des zweiten erfaßten Bogens.That arched into the interior of the captured With double sheet detection, the arc causes a relative movement of the two detected arches and thus repelling them of the second sheet detected.

Darüberhinaus kann sich das freie Ende des Faltenbalgs gut nach der Oberflache des Bogenstapels ausrichten, was auch ein Abweichen des Saugers von einer senkrechten Ausrichtung zur Bogenstapeloberflache ermöglicht.In addition, the free end of the bellows can align well with the surface of the sheet stack, which is also a deviation of the suction cup from a vertical one Alignment to the sheet stack surface enables.

Das Abstoßen des zweiten erfaßten Bogens wird noch weiter verstärkt, wenn die Saugfläche der Saugdüse eine von einer Ebene abweichende Form aufweist, da dann die von einer Ebene abweichende Form der Saugflache bei Anlage des vom Faltenbalg angehobenen Bogens an der Saugflache eine weitere Relativbewegung der zwei Bogen bei Doppelbogenerfassung bewirkt. Das sichere Abstoßen bzw. nicht Annehmen des zweiten Bogens ermöglicht sehr hohe Laufgeschwindigkeiten eines Bogenanlegers, dessen Teil der Sauger sein kann.The rejection of the second detected sheet continues reinforced when the suction surface of the suction nozzle is a has a shape deviating from a level, since then the form of the suction surface deviating from one level in the system of the bow raised by the bellows on the suction surface another relative movement of the two arches Double sheet detection causes. Safe repelling or not accepting the second sheet allows very high Running speeds of a sheet feeder, its part the sucker can be.

Das Abweichen der Saugfläche von einer Ebene kann durch die verschiedenartigsten Erhebungen oder Vertiefungen an der Saugfläche erreicht werden.The deviation of the suction surface from one level can be caused by the most diverse elevations or depressions can be reached at the suction surface.

Besonders einfach herstellbar ist es, wenn die Saugfläche konkav oder wenn die Saugfläche konvex ausgebildet ist. Dabei wird der zur Anlage an die Saugfläche gelangende Bogen konkav bzw. konvex gebogen und stößt so einen miterfaßten zweiten Bogen ab. Dies ist besonders vorteilhaft bei voluminösen Bogen.It is particularly easy to manufacture if the suction surface concave or if the suction surface is convex is. In doing so, it becomes a contact with the suction surface arches that are concave or convex bent and butt such a recorded second sheet. This is special advantageous for voluminous sheets.

Um je nach Art des Bogens eine optimale Saugfläche zu erhalten, kann die Saugdüse ein separates, an der Stirnseite des Saugerkörpers befestigbares Bauteil sein, das somit auswechselbar ist und die Verwendung der jeweils optimalen Saugdüse ermöglicht.In order to have an optimal suction surface depending on the type of sheet received, the suction nozzle can be a separate, on the Front side of the suction body attachable component be interchangeable and use the optimal suction nozzle.

Zum Auswechseln weist vorteilhafterweise die Saugdüse einen an ihrer der Saugfläche abgewandten Seite hervorstehenden Ansatz auf, der in eine entsprechende Ausnehmung in der Stirnseite des Saugerkörpers einsetzbar ist.The suction nozzle advantageously has a replacement a protruding on its side facing away from the suction surface Approach on the corresponding recess can be used in the front of the vacuum body is.

Um auf einfache und schnelle Weise eine Auswechselung der Saugdüse zu erreichen, kann die Saugdüse mit ihrem Ansatz in die Ausnehmung des Saugerkörpers einrastbar sein.To make a replacement in a simple and quick way To reach the suction nozzle, the suction nozzle can be used with your Approach snaps into the recess of the suction body be.

Dazu ist in einfacher Ausgestaltung vorzugsweise der Ansatz zylindrisch ausgebildet und weist an seinem freien Ende einen oder mehrere radial hervorstehende Rastansätze auf, die in eine entsprechende Rastausnehmung in der Ausnehmung des Saugerkörpers einrastbar sind.In a simple embodiment, this is preferably the Approach cylindrical and points to his free end one or more radially protruding Lugs on which in a corresponding recess Can be snapped into the recess of the sucker body are.

Leicht und einfach herstellbar ist es, wenn der Rastansatz ein radial umlaufender Ringansatz ist oder auch wenn die Rastausnehmung eine radial umlaufende Ringnut ist.It is easy and simple to manufacture if the latching attachment is or also a radially circumferential ring approach if the recess has a radial circumferential groove is.

Einer sicheren Erfassung des jeweils obersten Bogens eines Bogenstapels dient es, wenn der untere letzte Abschnitt des Faltenbalgs eine flexible Ringlippe bildend sich vom inneren Durchmesser zum äußeren Durchmesser des Faltenbalgs erstreckt, da sich dann die Ringlippe an den Bogen anschmiegen kann.Safe detection of the top sheet a stack of sheets it serves when the bottom last section of the bellows forming a flexible ring lip from the inner diameter to the outer diameter of the bellows, since then the ring lip can nestle against the arch.

Eine bauteilarme und leicht montierbare Ausbildung wird erreicht, wenn der Saugerkörper ein zylindrisches Befestigungsteil aufweist, an dessen zylindrischer Mantelfläche eine radial umlaufende Ringnut ausgebildet ist, in die das obere Ende des Faltenbalgs mit einem entsprechenden umlaufenden Rand einknüpfbar ist.A low-component and easy to install training is reached when the sucker body is a cylindrical fastener has, on the cylindrical lateral surface a radially circumferential annular groove is formed is in which the upper end of the bellows with a corresponding peripheral edge can be inserted.

Münden die Saugöffnungen gleichmäßig verteilt an der Saugfläche der Saugdüse nach außen, so wird der erfasste Bogen zumindest weitgehend vollständig an der Saugfläche zur Anlage gebracht und entsprechend deren Oberflächenform verformt, was einem sicheren Abwerfen eines miterfaßten zweiten Bogens dient.Mouth the suction openings evenly distributed on the Suction surface of the suction nozzle to the outside, so the detected Arch at least largely completely on the Brought suction surface to the system and accordingly Deformed surface shape, making it safe to throw off of a co-recorded second sheet.

Ein radial umlaufender Ringansatz 12 am freien Ende des Ansatzes 10 ist den Boden 21 hintergreifend eingerastet, wobei die Saugbohrung 20 eine Ringnut 13 zum Einrasten des Ringansatzes 12 bildet.In the recess 11 is the suction nozzle 6 with a corresponding one cylindrical approach 10 used. A radially circumferential ring approach 12 at the free end of the Approach 10 is engaged behind the bottom 21, wherein the suction bore 20 is an annular groove 13 for Snap the ring approach 12 forms.

Der dem Befestigungsteil 16 abgewandte Bereich der Saugdüse 6 besitzt einen größeren Durchmesser als die Ausnehmung 11 und liegt an der äußeren Stirnseite 5 des Befestigungsteils 16 an.The area facing away from the fastening part 16 Suction nozzle 6 has a larger diameter than that Recess 11 and lies on the outer end face 5 of the Fastening part 16.

Der in den Innenraum 2 des Faltenbalgs 1 der Saugdüse 6 ragende Teil der Saugdüse 6 besitzt eine konvexe Oberfläche, die eine Saugfläche 8 der Saugdüse 6 bildet.The inside of the bellows 1 of the suction nozzle 6 protruding part of the suction nozzle 6 has a convex surface, which forms a suction surface 8 of the suction nozzle 6.

In der Saugdüse 6 sind drei axial durchgehende Saugöffnungen 7 ausgebildet, die von der Saugbohrung 20 zum Innenraum 2 des Faltenbalgs 1 führen und an der Saugfläche 8 in diesen münden. Die drei Saugöffnungen 7 münden auf einem konzentrischen Teilkreis gleichmäßig verteilt in den Innenraum 2. There are three axially continuous suction openings in the suction nozzle 6 7 formed from the suction hole 20 to Guide the interior 2 of the bellows 1 and on the suction surface 8 flow into these. The three suction openings 7 flow evenly on a concentric pitch circle distributed in the interior 2.

Der letzte Abschnitt 14 am freien Ende 9 des Faltenbalgs 1 ist als flexible Ringlippe 15 ausgebildet. An diese Ringlippe 15 wird durch Unterdruckbeaufschlagung der Saugbohrung 20 und des Innenraums 2 der oberste Bogen eines Bogenstapels angesaugt. Dadurch wird die Öffnung des Faltenbalgs 1 geschlossen und bei weiterer Evakuierung dieser zusammengezogen, wodurch der erfaßte Bogen vom Bogenstapel getrennt und bis zur Anlage an der Saugfläche 8 der Saugdüse 6 angehoben wird.The last section 14 at the free end 9 of the bellows 1 is designed as a flexible ring lip 15.
