Abstract

The device for lifting flaps of envelopes at feeders of envelope closing machines uses a suction plate (30) in order to guide the open envelope flaps past a moistening device (50). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Abheben von Briefumschlagklappen an Zuführungen von Briefschließmaschinen.The invention relates to a device for lifting envelope flaps on feeders of letter closing machines.

Vorrichtung zum Abheben von Briefumschlagklappen, die durch mechanische Verformung ein Abspreizen der Briefklappe bewirken, gehören zum Stand der Technik (DE-26 32 913, DE-29 48 929). Die mechanische Verformung kann bei steifen oder stark gefüllten Umschlägen versagen, so daß der folgende Schließvorgang nicht ausführbar ist. Abhilfe schafft eine Vorrichtung, die impulsförmiges Ausstoßen von Luft gegen einen Briefumschlag dessen Klappe soweit hebt, daß ihr Gummierung nachfolgend von einer Anfeuchteinrichtung benetzt werden kann (DE-33 37 488). Diese Vorrichtung erfordert einen Niederhalter, dessen Andruckkraft ggf. auf die Briefstärke und die Luftstromstärke abzustimmen ist.Devices for lifting envelope flaps, which cause the letter flap to expand due to mechanical deformation, belong to the prior art (DE-26 32 913, DE-29 48 929). The mechanical deformation can fail with stiff or heavily filled envelopes, so that the following closing process cannot be carried out. This is remedied by a device which impulses expelling air against an envelope lifts its flap so far that its rubber coating can subsequently be wetted by a moistening device (DE-33 37 488). This device requires a hold-down device, the pressure of which may need to be matched to the letter strength and the air flow strength.

Der Erfindung lag die Aufgabe zugrunde, eine Vorrichtung zum Abheben von Briefumschlagklappen zu schaffen, die das Verarbeiten sowohl offener als auch geschlossener Briefe, unabhängig von deren Stärke, gestattet, ohne den Einsatz eines Niederhalters.The invention had for its object to provide a device for lifting envelope flaps, which allows the processing of both open and closed letters, regardless of their strength, without the use of a hold-down device.

Diese Aufgabe ist dadurch gelöst, daß der Zuführung eine perforierte Saugplatte mit nachgeordneter Trennplatine zugeordnet ist, wobei eine Kante der Saugplatte unter einer Kante der Trennplatine liegt.This object is achieved in that the feed is assigned a perforated suction plate with a subordinate separating plate, one edge of the suction plate being located below an edge of the separating plate.

Anhand einer aus zwei Figuren bestehenden Zeichnung wird die Erfindung nachfolgend näher erläutert. Darin zeigt die

Fig. 1
den Schnitt durch die Seitensicht und die
Fig. 2
die Aufsicht auf einen Teil der Vorrichtung zum Abheben von Briefumschlagklappen.
The invention is explained in more detail below on the basis of a drawing consisting of two figures. In it shows the
Fig. 1
the cut through the side view and the
Fig. 2
supervision of part of the device for lifting envelope flaps.

Der Briefumschlag 10 läuft nach der Vereinzelung durch die Förderwelle 21 und die Andruckrolle 22 über eine perforierte Saugplatte 30. Der Saugplatte 30 ist eine Trennplatine 40 nachgeordnet. Dabei liegt die der Trennplatine 40 zugewandte Kante der Saugplatte 30 unter der vorderen Kante der Trennplatine 40, gesehen in Transportrichtung eines Briefumschlages. Die Oberfläche der Saugplatte 30 ist konvex gewölbt. Über einen Saugstutzen 31 wird, gesteuert von nicht dargestellten Abtasteinrichtungen, z. B. Lichtschranken, Luft durch die Perforierung abgesaugt. Von einem über die Saugplatte 30 geführten unverschlossenen Brief 10 wird dadurch die Briefumschlagklappe angesaugt und gleitet unter die Trennplatine 40. Die nachgeordnete Anfeuchteinrichtung 50 benetzt die Gummierung und eine nicht gezeigte Andruckvorrichtung schließt den Brief.After being separated, the envelope 10 runs through the conveyor shaft 21 and the pressure roller 22 via a perforated suction plate 30. A separation plate 40 is arranged downstream of the suction plate 30. The edge of the suction plate 30 facing the separating plate 40 lies below the front edge of the separating plate 40, viewed in the transport direction of an envelope. The surface of the suction plate 30 is convexly curved. About a suction port 31 is controlled by scanning devices, not shown, for. B. light barriers, sucked air through the perforation. As a result, the envelope flap is sucked in by an unsealed letter 10 guided over the suction plate 30 and slides under the separating board 40. The downstream moistening device 50 wets the rubber coating and a pressure device, not shown, closes the letter.

Gelangt ein bereits verschlossener Brief an die Saugplatte 30, wird dieser aufgrund der geringen Saugleistung sowie seiner Steifigkeit über die Trennplatte 40 geleitet.If a letter that has already been closed arrives at the suction plate 30, it is passed over the separating plate 40 due to the low suction power and its rigidity.

In weiterer Ausgestaltung der Vorrichtung ist als Abtasteinrichtung die Führungsfläche für den Briefumschlag 10 vor der Förderwelle 21 mit einer Aussparung versehen, die die Briefumschlagklappe gegenüber dem überwiegenden Teil des Briefumschlages 10 nicht unterstützt. Die Briefumschlagklappe ist damit der Schwerkraft ausgesetzt und hängt in der Aussparung, wobei sie beispielsweise einen Lichtstrahl unterbricht. Durch Lagedetektoren wird ermittelt, ob der Brief verschlossen ist und dementsprechend die Saugvorrichtung gesteuert.In a further embodiment of the device, the guide surface for the envelope 10 is provided with a recess in front of the conveyor shaft 21 as a scanning device, which recess does not support the envelope flap in relation to the predominant part of the envelope 10. The envelope flap is thus exposed to gravity and hangs in the recess, for example interrupting a light beam. Position detectors determine whether the letter is closed and the suction device is controlled accordingly.

Anstelle der Abtasteinrichtung des Schließzustandes eines Briefes durch Schwerkrafteinwirkung kann auch die eingangs genannte Vorrichtung des Luftstrom-Ausstoßens oder eine vereinfachte Ansaugvorrichtung verwendet werden.Instead of the scanning device of the closed state of a letter due to the action of gravity, the above-mentioned device of air flow ejection or a simplified suction device can also be used.
