Description

Die Erfindung bezieht sich auf eine Anfeuchteinrichtung für Briefklappen gemäß dem Oberbegriff des Patent­anspruches 1.The invention relates to a moistening device for letter flaps according to the preamble of claim 1.

Für das automatische Verschließen von Briefen wird die gummierte Klappe des Briefes über eine Anfeuchteinrichtung geführt, die die gummierte Fläche der Klappe durch An­feuchten bzw. Aufweichen des Leimes aufbereitet. Ein nachfolgendes Andrücken der Klappe verschließt den Brief. Zum Anfeuchten dient ein aus einem Flüssigkeitsbehälter führender Anfeuchtstreifen, über den die Briefklappe geführt wird (DE-PS 15 11 420) oder eine Bürste wird durch geeignete Hilfsmittel benetzt (DE-AS 15 61 881, DE-PS 33 37 488). Bei der Verwendung von Bürsten liegen allgemein die Bürstenhaare auf mit Flüssigkeit getränkten Kissen, Schwämmen oder Rollen auf, die die Flüssigkeit resorbieren und zwischen zwei vorbeilaufenden Briefen an die Bürstenhaare abgeben. Von den Bürstenhaaren gelangt die Feuchtigkeit an die Gummierung der Briefklappe. Das Aufnahmevermögen einer Bürste an Flüssigkeit ist jedoch relativ gering. Außerdem verkürzt sich die Zeit für die Flüssigkeitsaufnahme über Kissen, Schwämme oder Rollen bei einer hohen Durchlaufgeschwindigkeit der Briefe. Dies führt bei der Anfeuchtung der Klappen größerer Brief­formate und insbesondere der Klappen, die über die längere Briefkante geschlossen werden sollen, nur zu partieller Anfeuchtung und damit zum unvollkommenen Schließen.For the automatic closing of letters, the rubberized flap of the letter is guided over a moistening device, which processes the rubberized surface of the flap by moistening or softening the glue. Subsequent pressing of the flap closes the letter. A moistening strip leading from a liquid container is used for moistening, over which the letter flap is guided (DE-PS 15 11 420) or a brush is wetted by suitable aids (DE-AS 15 61 881, DE-PS 33 37 488). When using brushes, the brush hair generally rests on pillows, sponges or rollers soaked in liquid, which absorb the liquid and deliver it to the brush hair between two passing letters. The moisture from the brush hair reaches the rubber lining of the letter flap. However, the ability of a brush to absorb liquid is relatively low. It also shortens the time it takes for fluids to be absorbed by pillows, sponges or rollers when the letters run at high speeds. When the flaps of larger letter formats and in particular the flaps which are to be closed over the longer edge of the letter are moistened, this only leads to partial moistening and thus to imperfect closure.

Der Erfindung lag die Aufgabe zugrunde, eine Anfeucht­einrichtung für Briefklappen zum Auftragen der Feuchtig­keit mittels Bürsten zu schaffen, die auch bei hoher Durchlaufgeschwindigkeit ständig einen genügenden Flüssig­keitsvorrat an der Bürste gewährleistet.The invention had for its object to provide a moistening device for letter flaps for applying the moisture by means of brushes, which constantly ensures a sufficient liquid supply on the brush even at high throughput speeds.

Diese Aufgabe ist durch die Erfindung gelöst, wie sie im Kennzeichnungsteil des ersten Patentanspruches darge­legt ist.This object is achieved by the invention as set out in the characterizing part of the first claim.

Anhand einer prinzipiellen Darstellung wird die Erfindung nachfolgend näher erläutert, wobei die

  • Fig. 1 den Schnitt durch eine Anfeuchteinrichtung, bei der die anzufeuchtenden Briefklappen zum Beispiel auf den Betrachter zulaufen, zeigt und die
  • Fig. 2 einen Schnitt längs der Linie A-A der Figur 1 darstellt.
The invention is explained in more detail below on the basis of a basic illustration, the
  • Fig. 1 shows the section through a moistening device, in which the letter flaps to be moistened, for example, run towards the viewer, and
  • Fig. 2 shows a section along the line AA of Figure 1.

In beiden Figuren tragen gleiche Ausformungen dieselben Bezugszeichen.In both figures, the same formations have the same reference numerals.

Die Anfeuchteinrichtung besteht aus einem Flüssigkeits­behälter (1), der die Flüssigkeit (2) und einen auf einer Stütze (3) liegenden Schwamm (4) aufnimmt. Die Verwendung einer Stütze (3) gewährleistet das Vorhandensein eines nicht aufgesaugten Flüssigkeitsvorrates. Der Schwamm (4) ist mittels eines Halters (5) in seiner Lage fixiert.The moistening device consists of a liquid container (1) which holds the liquid (2) and a sponge (4) lying on a support (3). The use of a support (3) ensures the presence of an unabsorbed liquid supply. The sponge (4) is fixed in its position by means of a holder (5).

Oberhalb des Behälters (1) ist ein Bürstenhalter (6) federnd gelagert, der die Bürste (7) und einen über die Länge der Bürste (7) reichenden Saugstreifen (8) trägt. Die Haare der Bürste (7) liegen auf dem Schwamm (4) und nehmen von diesem Flüssigkeit auf, solange keine Brief­klappe zwischen Bürste (7) und Halter (5) zum Anfeuchten durchgeführt wird. Das abgewinkelte Ende (9) des Saug­streifens (8) liegt konstant in der Flüssigkeit (2). Dadurch wird die Bürste (7) ständig mit Flüssigkeit ver­sorgt, unabhängig von der Durchlaufgeschwindigkeit und damit ggf. des schnellen Aufeinanderfolgens der zu schließenden Briefe.Above the container (1), a brush holder (6) is spring-mounted, which carries the brush (7) and a suction strip (8) extending over the length of the brush (7). The hair of the brush (7) lies on the sponge (4) and absorbs liquid from it as long as there is no letter flap between the brush (7) and holder (5) for moistening. The angled end (9) of the suction strip (8) lies constantly in the liquid (2). As a result, the brush (7) is constantly supplied with liquid, regardless of the throughput speed and thus, if necessary, the rapid succession of the letters to be closed.

Für einen geringeren Durchsatz an zu schließenden Briefen, für kleinere Formate sowie für geringere Papierqualitäten, wie z. B. Recyclingpapiere, kann die Flüssigkeitsmenge an der Bürste (7) zu groß sein. In diesem Fall wird ein Saugstreifen (8) verwendet, dessen Ende nicht in die Flüssigkeit taucht. Der Saugstreifen (8) dient in diesem Fall als Flüssigkeitsspeicher. Die Flüssigkeit selbst wird, wie in den eingangs dargestellten Fällen, durch die Bürstenhaare direkt vom Schwamm (4) aufgenommen, wobei ein Teil an den Saugstreifen (8) abgegeben wird.For a lower throughput of letters to be closed, for smaller formats and for lower paper qualities, such as. B. recycled paper, the amount of liquid on the brush (7) may be too large. In this case, a suction strip (8) is used, the end of which is not immersed in the liquid. In this case, the suction strip (8) serves as a liquid reservoir. As in the cases described at the beginning, the liquid itself is absorbed directly by the sponge (4) through the brush hairs, part of which is given off to the suction strip (8).

Als Material für den Schwamm (4) und den Saugstreifen (8) wird poröses Material verwendet, beispielsweise Filze, Vliese oder großporige Schaumstoffe. Dabei kann abhängig vom Einsatz für den schnellen oder langsameren Durchlauf unterschiedliches Material für den Schwamm (4) und den Saugstreifen (8) verwendet werden.Porous material is used as the material for the sponge (4) and the suction strip (8), for example felts, nonwovens or large-pore foams. Different materials can be used for the sponge (4) and the suction strip (8) depending on the application for the fast or slower run.
