Abstract

An apparatus for removing the content from envelopes having two adjacent edges opened by slitting or cutting is equipped with two facing suction devices. At least one suction device is movable perpendicular to the envelope plane for separating the envelope. During the operating phase, one suction device is movable with respect to the other in the envelope plane in order to effect a relative movement between the envelope and the contents of the envelope. This facilitates removal because the envelope held by the suction device is additionally deformed, i.e., given a corrugated configuration by the movement in the envelope plane. As a result, easy removal of the envelope content is possible.

Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a device according to the preamble of claim 1.

Bei einer bekannten Vorrichtung der vorstehend genannten Art werden die an einer Längskante geöffneten Umschläge durch zwei einander gegenüberliegende Sauger getrennt. Zu diesem Zweck ist mindestens einer der beiden Sauger senkrecht zur Umschlagebene bewegbar. Nach dem Trennen ist es grundsätzlich möglich, den Inhalt des Briefumschlages zu entnehmen. Dieses Entnehmen kann beispielsweise dadurch erschwert werden, daß der Briefbogen innen an der einen Umschlagseite anliegt oder von einem Sauger mit angesaugt wird. Letzteres ist insbesondere bei dünnen Umschlägen der Fall. Ein automatisches Entnehmen durch die maschinelle Einrichtung ist bei der bekannten Vorrichtung nicht möglich (DT-OS 25 43 692).In a known device of the type mentioned above, the envelopes opened on one longitudinal edge are separated by two suction cups located opposite one another. For this purpose, at least one of the two suction cups can be moved perpendicular to the handling plane. After separating, it is generally possible to remove the contents of the envelope. This removal can be made more difficult, for example, by the fact that the letter sheet rests on the inside of one cover page or is sucked in by a sucker. The latter is particularly the case with thin envelopes. Automatic removal by the machine is not possible with the known device (DT-OS 25 43 692).

Es ist weiterhin eine Vorrichtung zum Verarbeiten von Briefumschlägen bekannt, die zwei gegenüberliegende Sauger aufweist, um den lediglich an einer Kante geschlitzten Briefumschlag zu öffnen. Einer der Sauger ist in bezug auf den anderen zusätzlich in der Umschlagebene verstellbar. Diese Verstellung in der Umschlagebene geschieht aber nicht dann, wenn sich ein Umschlag zwischen den Saugern befindet, sondern im Stillstand, um eine Anpassung an das Umschlagformat zu ermöglichen. Der entsprechende Sauger wird jeweils möglichst nahe an die geschlitzte Kante heranbewegt (DE-OS 27 32 936).A device for processing envelopes is also known, which has two suction cups located opposite one another in order to open the envelope, which is only slit on one edge. One of the suction cups is additionally adjustable in relation to the other in the envelope level. This adjustment in the envelope level does not occur when there is an envelope between the suction cups, but at a standstill to allow adaptation to the envelope format. The corresponding suction cup is moved as close as possible to the slotted edge (DE-OS 27 32 936).

Diese Aufgabe wird durch das Kennzeichen des Anspruches 1 gelöst.This object is achieved by the characterizing part of claim 1.

Erfindungsgemäß sind die beiden Sauger nicht nur senkrecht zur Umschlagebene bewegbar, um die geöffneten Umschlagseiten zu trennen, sondern der eine Sauger ist darüber hinaus während der Öffnungphase in der Umschlagebene bewegbar, um die Relativbewegung zwischen Umschlag und Briefinhalt durchzuführen. Hierdurch wird die Entnahme erleichtert, da der durch die Sauger festgehaltene Umschlag durch die Bewegung in der Umschlagebene zusätzlich verzerrt wird, d. h. er wird gewellt, so daß der nicht gewellte Briefbogen leicht entnommen werden kann. Wenn der Umschlag in vorteilhafter Weise an zwei aneinander angrenzenden Kanten durch Schneiden oder Schlitzen geöffnet wurde, so wird der Briefbogen durch die Relativbewegung gegenüber dem Umschlag an der einen geschlitzten Kante herausgeschoben, wodurch wiederum die Entnahme erleichtert wird. Durch diese erfindungsgemäße Vorbereitung der Entnahme ist es darüber hinaus möglich, ein automatisches maschinelles Entnehmen durch einen Greifer oder dergleichen durchzuführen, und zwar dadurch, daß eine eindeutige Trennung der Umschlagseiten von dem Briefbogen durchgeführt wird. Weiterhin löst die Relativbewegung zwischen Briefbogen und Umschlag einen eventuell bei dünnen Umschlägen mit angesaugten Briefbogen von der entsprechenden Umschlagseite. In vorteilhafter Weise ist es möglich, die Sauger in der Umschlagebene gegeneinander versetzt anzuordnen. Hierdurch wird verhindert, daß bei dünnen, entsprechend luftdurchlässigen Briefen ein Festsaugen aneinander erfolgt, welches ein Trennen verhindern könnte.According to the invention, the two suction cups are not only movable perpendicular to the envelope level in order to separate the opened envelope pages, but the one suction cup is also movable in the envelope plane during the opening phase in order to carry out the relative movement between the envelope and the letter content. This makes removal easier, since the envelope held by the suction cups is additionally distorted by the movement in the envelope plane, i. H. it is corrugated so that the non-corrugated letterhead can be easily removed. If the envelope has advantageously been opened on two adjacent edges by cutting or slitting, the letterhead is pushed out by the relative movement relative to the envelope on the one slotted edge, which in turn makes removal easier. Through this preparation of the removal according to the invention, it is also possible to carry out an automatic machine removal by means of a gripper or the like, namely by carrying out a clear separation of the cover pages from the letterhead. Furthermore, the relative movement between letterhead and envelope triggers a possibly thin envelope with the letterhead sucked in from the corresponding cover page. In an advantageous manner, it is possible to arrange the suction cups offset from one another in the envelope plane. This prevents that, in the case of thin, air-permeable letters, suction occurs against one another, which could prevent separation.

Schließlich ist es noch möglich, an dem einen Sauger bei in der Umschlagebene versetzt angeordneten Saugern, und zwar an demjenigen, der senkrecht zur Umschlagebene bewegbar ist, einen Gegenhalt für den anderen Sauger vorzusehen. Hierdurch wird sichergestellt, daß der in den Bereich der Sauger transportierte und bereits durch Schlitzen oder Schneiden geöffnete Umschlag auch sicher angesaugt wird, da der Gegenhalter den Umschlag auf den anderen Sauger drückt.Finally, it is still possible to provide a counter for the other suction device on one suction device in the case of suction devices arranged offset in the handling plane, specifically on the one that can be moved perpendicular to the handling plane. This ensures that the envelope transported into the area of the suction cups and already opened by slitting or cutting is also safely sucked in, since the counter-holder presses the envelope onto the other suction cups.

In vorteilhafter Weise kann die Vorrichtung noch mit einer Lichtquelle versehen sein, die mit vorzugsweise gebündeltem Licht den geöffneten Umschlag ausleuchtet. Hierdurch wird einerseits beim Entnehmen ein gezieltes Zugreifen und zum anderen eine Sichtkontrolle ermöglicht, durch die auch sichergestellt wird, daß der vollständige Inhalt entnommen wird.Advantageously, the device can also be provided with a light source which illuminates the opened envelope with preferably focused light. In this way, targeted access is made possible on the one hand, and on the other hand a visual inspection is made possible, which also ensures that the complete content is removed.

Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles näher erläutert.The invention is explained in more detail below with reference to the drawing using an exemplary embodiment.

Es zeigt :

  • Figur 1 eine perspektivische Ansicht einer Ausführungsform mit zwei Schneidwerken der gesamten Vorrichtung nach der Erfindung ;
  • Figur 2 eine schematische Seitenansicht eines zu entleerenden Umschlages vor der Relativbewegung der Sauger senkrecht zur Umschlagebene ;
  • Figur 3 eine der Fig. 2 entsprechende Ansicht, jedoch nach Durchführung der Bewegung eines Saugers senkrecht zur Umschlagebene ; und
  • Figur 4 eine den Fig. 2 und 3 entsprechende Ansicht jedoch nach Durchführung der zusätzlichen Bewegung eines Saugers in der Umschlagebene in Richtung auf eine geöffnete Kante.
It shows :
  • Figure 1 is a perspective view of an embodiment with two cutting units of the entire device according to the invention;
  • FIG. 2 shows a schematic side view of an envelope to be emptied before the suction cups move relative to the envelope plane;
  • Figure 3 is a view corresponding to Figure 2, but after performing the movement of a suction device perpendicular to the envelope plane. and
  • 4 shows a view corresponding to FIGS. 2 and 3, however, after carrying out the additional movement of a suction device in the envelope plane in the direction of an open edge.

Die in Fig. 1 dargestellte Vorrichtung, die auch als Posteingangs/platz oder Briefentnahmestation bezeichnet werden kann, ist in einem Gestell 1 untergebracht. Die Briefumschläge werden aus einem Magazin 2 einzeln durch einen schwenkbaren Sauger 3 auf einen Förderer 4 aufgegeben und bei 5 an ihrer einen Kante geschlitzt. Sie werden dann durch die Einrichtung 6 auf einen zweiten Förderer 8 transportiert. Hierbei wird bei 7 die angrenzende Kante geschlitzt. Der Förderer 8 fördert den auf diese Weise an zwei Kanten geschlitzten Umschlag 11 in den Bereich der Sauger 9 und 10, die - wie den Fig. 2 bis 4 zu entnehmen - in der Umschlagebene gegeneinander versetzt angeordnet sind. Weiterhin ist im Bereich des Förderers 8 ein Anschlag 13 für die unten liegende Umschlagseite vorgesehen.The device shown in FIG. 1, which can also be referred to as a post office / place or letter removal station, is accommodated in a frame 1. The envelopes are individually fed from a magazine 2 through a swiveling suction device 3 onto a conveyor 4 and slit at 5 on one edge thereof. They are then transported by the device 6 to a second conveyor 8. Here the adjacent edge is slit at 7. The conveyor 8 conveys the envelope 11 slit in this way on two edges into the area of the suction devices 9 and 10 which, as can be seen in FIGS. 2 to 4, are arranged offset with respect to one another in the envelope plane. Furthermore, a stop 13 is provided in the area of the conveyor 8 for the cover page located below.

An dem Sauger 9, der senkrecht zu der Umschlagebene schwenkbar ist, ist ein Gegenhalter 14 für den anderen Sauger 10 vorgesehen.On the suction cup 9, which is perpendicular to the order plane is pivotable, a counter-holder 14 is provided for the other suction device 10.

Wenn ein zu entleerender Umschlag den Bereich der Sauger 9 und 10 erreicht hat und die in Fig. 2 gezeigte Stellung, die durch den Anschlag 13 festgelegt ist, einnimmt, wird der Sauger 9 auf den Umschlag geschwenkt. Hierdurch gelangt der Sauger 9 mit der ihm zugekehrten Umschlagseite zur Anlage. Durch den Gegenhalter 14 wird die andere Umschlagseite gegen den anderen Sauger 10 gedrückt. Nunmehr erfolgt das Ansaugen durch die Sauger 9 und 10. Der Sauger 9 wird zurückgeschwenkt, so daß der Briefumschlag 11 mit dem Brief 12 die in Fig. 3 gezeigte Form annimmt. Nunmehr wird der andere Sauger 10 in der Umschlagebene um den Hub a in Richtung auf die geöffnete Kante, d. h. in Richtung auf den Anschlag 13, bewegt. Die Teile nehmen hierbei die in Fig. 4 veranschaulichte Lage ein.When an envelope to be emptied has reached the area of the suction cups 9 and 10 and assumes the position shown in FIG. 2, which is defined by the stop 13, the suction cup 9 is pivoted onto the envelope. As a result, the suction device 9 comes to rest with the cover side facing it. The other cover side is pressed against the other sucker 10 by the counter-holder 14. Now the suction takes place through the suction cups 9 and 10. The suction cup 9 is swung back so that the envelope 11 with the letter 12 takes the form shown in FIG. 3. Now the other sucker 10 is in the envelope level by the stroke a in the direction of the open edge, d. H. in the direction of the stop 13. The parts assume the position illustrated in FIG. 4.

Es wird deutlich, daß die Umschlagseiten eine vergrößerte Verzerrung oder Wellenform zeigen. Bereits hierdurch kann der Briefbogen 12 leicht entnommen werden. Weiterhin wird deutlich, daß die linke geschlossene Kante nach oben und nach rechts bewegt wird und zwar nach rechts ungefähr in der Größenordnung des Hubes a des Saugers 10. Um das entsprechende Stück wird der Briefbogen 12 aus der anderen geöffneten Kante herausbewegt. Dieses erleichtert und vereinfacht ebenfalls die Entnahme. Eine automatische Entnahme durch einen nicht gezeigten Greifer ist ohne weiteres möglich.It can be seen that the cover pages show an enlarged distortion or waveform. In this way, the letterhead 12 can easily be removed. Furthermore, it is clear that the left closed edge is moved upwards and to the right, to the right approximately in the order of magnitude of the stroke a of the sucker 10. The letterhead 12 is moved out of the other opened edge by the corresponding piece. This also simplifies and simplifies removal. Automatic removal by a gripper, not shown, is readily possible.

Sollte der Briefbogen die in Fig. 3 gezeigte Stellung einnehmen, so wird diese Lage bei Einnahme der Stellung nach Fig. 4 wieder gelöst, da eine Relativbewegung in der Umschlagebene zwischen Umschlag und Briefbogen stattfindet.If the letterhead assumes the position shown in FIG. 3, this position is released again when the position according to FIG. 4 is assumed, since there is a relative movement in the envelope level between the envelope and the letterhead.

Dadurch, daß die beiden Sauger 9 und 10 in der Umschlagebene gegeneinander versetzt angeordnet sind, können sie sich bei dünnen Briefen nicht gegenseitig ansaugen und so ein Öffnen überhaupt verhindern. Der Gegenhalter 14 stellt sicher, daß so wenig Nebenluft wie möglich bei Betätigung des Saugers 10 angesogen wird.The fact that the two suction cups 9 and 10 are offset from one another in the envelope plane means that they cannot suck each other in thin letters and thus prevent them from opening at all. The counter-holder 14 ensures that as little secondary air as possible is sucked in when the suction device 10 is actuated.

Die entnommenen Briefbögen können zweckmäßig in die verschiedenen, in Fig. 1 gezeigten Ablagefächer einsortiert werden.The removed letterheads can expediently be sorted into the various storage compartments shown in FIG. 1.

In der Zeichnung, insbesondere Fig. 1 wurden zwei Schneidwerke 5 und 7 dargestellt. Im Rahmen der Erfindung ist es aber auch möglich, ein drittes Schneidwerk an der dem Schneidwerk 7 gegenüberliegenden Seite vorzusehen, um auch die dritte Kante des Briefumschlages zu schlitzen. Bei dieser Ausführungsform mit drei Schneidwerken wird zuerst die Kante mit dem in Fig. 1 nicht dargestellten Schneidwerk geöffnet. Im Anschluß daran, ist der Funktionsablaufso wie in Verbindung mit der Fig. 1 beschrieben. Auch bei der Öffnung an drei Kanten entsteht die erwünschte « Wellenform •.In the drawing, in particular Fig. 1, two cutting units 5 and 7 were shown. In the context of the invention, however, it is also possible to provide a third cutter on the side opposite the cutter 7 in order to also slit the third edge of the envelope. In this embodiment with three cutting units, the edge is first opened with the cutting unit not shown in FIG. 1. Following this, the functional sequence is as described in connection with FIG. 1. The desired “wave shape” is also created when opening on three edges.

Eine Lichtquelle 15, die in den geöffneten Umschlag leuchtet, ist ebenfalls vorgesehen, wie in den Fig. 1 und 4 dargestellt.A light source 15 that shines in the opened envelope is also provided, as shown in FIGS. 1 and 4.
