Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Patentanspruches l. Eine derartige Vorrichtung ist aus der europäischen Patentschrift 0 036 94l bekannt. Der eine Saugarm dieser bekannten Vorrichtung ist nicht nur senkrecht zur Umschlagebene sondern auch in der Umschlagebene bewegbar, so daß eine Relativbewegung zwischen Umschlag und Briefinhalt erzeugt wird. Hierdurch wird der Umschlag zusätzlich verzerrt, d.h. gewellt, so daß er sich sicher von dem Briefinhalt trennt und dieser leicht entnommen werden kann. Es soll hierdurch vermieden werden, daß versehentlich nicht der gesamte Inhalt entnommen wird.The invention relates to a device according to the preamble of claim 1. Such a device is known from European Patent 0 036 94l. One suction arm of this known device can be moved not only perpendicularly to the envelope plane but also in the envelope plane, so that a relative movement between the envelope and the letter content is generated. This will further distort the envelope, i.e. curled so that it separates safely from the letter content and this can be easily removed. This is to prevent the entire content from being accidentally removed.

Zum Stand der Technik gehört auch die DE-OS 27 32 936, die aber keine Möglichkeit eröffnet, den einen Saugarm zusätzlich in der Umschlagebene zu bewegen.The prior art also includes DE-OS 27 32 936, which, however, does not open the possibility of additionally moving one suction arm in the envelope level.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Vorrich­tung der eingangs genannten Art zu schaffen, mit hoher Entnahme- und Betriebssicherheit, um die Entleerung von Briefumschlägen in den unterschiedlichsten Formaten und auch dickerer und schwererer Umschläge zu gewährleisten.The invention is based on the object of creating a device of the type mentioned at the outset, with high removal and operational reliability, in order to ensure the emptying of envelopes in a wide variety of formats and also thicker and heavier envelopes.

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

Dadurch, daß der Umschlag waagerecht transportiert wird, können Umschläge unterschiedlicher Größe (z.B. 90 bis l80 mm Breite) und unterschiedlicher Dicke (bis zu 6 mm) bearbeitet werden. Diese waagerecht bewegten Umschläge werden dann durch das Tischsegment im Bereich der Sauger hochgeschwenkt, so daß die Bedienungsperson ohne Sichtbehinderung in den durch die Sauger geöffneten Umschlag einsehen kann. Der Umschlag liegt hierbei sicher auf dem Tischsegment auf und auch zwar dann, wenn es sich um einen sehr dünnen, beispielsweise um einen Luftpostumschlag, handelt. Das Tischsegment stützt den Umschlag in seiner eigentlichen Entnahmestellung, so daß die Sauger ihm die Form geben können, die zur Entnahme besonders günstig ist.Because the envelope is transported horizontally, envelopes of different sizes (e.g. 90 to 180 mm width) and different thicknesses (up to 6 mm) can be processed. These horizontally moved envelopes are then pivoted up through the table segment in the area of the suction cups, so that the operator can see into the envelope opened by the suction cups without obstructing vision. The envelope lies securely on the table segment, even if it is a very thin envelope, for example an airmail envelope. The table segment supports the envelope in its actual removal position so that the suction cups can give it the shape that is particularly favorable for removal.

Es sind nun zwei Ausführungsformen möglich, nämlich eine, bei der der in der Transportebene liegende untere Sauger getrennt von dem Segment ausgebildet und unabhängig von diesem bewegbar ist. Diese Ausführungsform ermöglicht einen sehr universellen Einsatz.Two embodiments are now possible, namely one in which the lower suction cup lying in the transport plane is formed separately from the segment and can be moved independently of it. This embodiment enables a very universal use.

Bei der anderen Ausführungsform ist der untere Sauger praktisch fest mit dem Tischsegment verbunden und daher mit diesem gemeinsam bewegbar. Diese Ausführungsform ist einfacher und damit wirtschaftlicher zu realisieren.In the other embodiment, the lower suction cup is practically firmly connected to the table segment and can therefore be moved together with it. This embodiment is simpler and therefore more economical to implement.

In besonders vorteilhafter Weise ist es nun möglich, zu der Bewegung der Sauger senkrecht zur Umschlagebene eine an sich bekannte weitere Bewegung im wesentlichen in der Umschlag­ebene durch den einen Sauger, vorzugsweise den nicht in der Transportebene liegenden oberen Sauger, sicherzustellen. Hierdurch wird der Umschlag verzerrt, d.h. er bekommt eine Wellenform, die sich von derjenigen des Inhaltes unterscheidet, so daß der Inhalt sicher erkannt, ergriffen und entnommen werden kann. Es ist praktisch ausgeschlossen, daß die Bedienungsperson den Inhalt übersehen kann.In a particularly advantageous manner, it is now possible, in addition to the movement of the suction cups perpendicular to the envelope plane, to ensure a further movement known per se essentially in the envelope plane through the one suction cup, preferably the upper suction cup not lying in the transport plane. As a result, the envelope is distorted, ie it receives one Waveform that differs from that of the content so that the content can be recognized, grasped and extracted safely. It is virtually impossible for the operator to miss the content.

Die zusätzliche Bewegung in der Umschlagebene kann in vorteilhafter Weise eine Kippbewegung um einen entsprechenden Kippwinkel sein. Hierzu wird der den Sauger tragende Saugarm um seine Längsachse gedreht. Diese Art der zusätzlichen Bewegung ist wirksam und läßt sich einfach realisieren.The additional movement in the envelope plane can advantageously be a tilting movement by a corresponding tilting angle. For this purpose, the suction arm carrying the suction cup is rotated about its longitudinal axis. This type of additional movement is effective and is easy to implement.

Weitere vorteilhafte Ausgestaltungen sind Gegenstand weiterer Unteransprüche.Further advantageous embodiments are the subject of further subclaims.

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:

  • Fig. l eine perspektivische Ansicht einer Ausführungsform einer Vorrichtung nach der Erfindung;
  • Fig. 2 eine schematische Schnittdarstellung quer zur Transportebene durch die wesentlichen Teile der Vorrichtung nach Fig. l;
  • Fig. 3 eine schematische Ansicht aus der Sicht der Bedienungsperson einschließlich einer darunterliegenden Draufsicht;
  • Fig. 4 eine schematische Ansicht aus der Sicht der Bedienungsperson mit senkrecht zur Umschlagebene bewegten Saugern;
  • Fig. 5 eine der Fig. 4 entsprechende Ansicht, jedoch mit zusätzlich in der Umschlagebene durch eine Kippbewegung bewegten oberen Sauger; und
  • Fig. 6 eine der Fig. 5 entsprechende Ansicht, jedoch mit einem zusätzlichen Vorsprung an­grenzend an den unteren Sauger zur Erzeugung einer weiteren Verwerfung der unteren Umschlagseite.
It shows:
  • Fig. L is a perspective view of an embodiment of a device according to the invention;
  • FIG. 2 shows a schematic sectional illustration transversely to the transport plane through the essential parts of the device according to FIG. 1;
  • Figure 3 is a schematic view from the operator's point of view including an underlying plan view.
  • Figure 4 is a schematic view from the operator's point of view with suction cups moved perpendicular to the envelope plane.
  • FIG. 5 shows a view corresponding to FIG. 4, but with the upper suction device additionally moved in the envelope plane by a tilting movement; and
  • Fig. 6 is a view corresponding to FIG. 5, but with an additional protrusion adjacent to the lower sucker for producing a further warping of the lower cover page.

Die in der Zeichnung, insbesondere in Fig. l, dargestellte Vorrichtung zeigt ein Entnahmegerät l und ein Untertisch­aggregat 2, in dem der Starkstromteil und die Vakuumpumpe untergebracht sind. Durch die Trennung des Untertisch­aggregates von dem Entnahmegerät kann das Entnahmegerät auch an einem anderen Ort als das Untertischaggregat eingesetzt werden. Ein Arbeitstisch 3 trägt das Entnahmegerät und eine Umschlagablage. Weiterhin ist ein Sortierfach strich­punktiert angedeutet.The device shown in the drawing, in particular in FIG. 1, shows a removal device 1 and an under-table unit 2, in which the high-voltage part and the vacuum pump are accommodated. By separating the under-table unit from the removal device, the removal device can also be used at a different location than the under-table unit. A work table 3 carries the removal device and an envelope tray. Furthermore, a sorting compartment is indicated by dash-dotted lines.

Der Standpunkt 6 für die Bedienungsperson befindet sich vor einer mit 5 bezeichneten Entnahmefläche. Die zu öffnenden Briefumschläge l8 werden in einem Ablageschacht 7 angeordnet. Aus dem Ablageschacht 7 werden sie durch einen Sauger an einem Saugarm 8 entnommen. Die Steuerung erfolgt durch eine Fotozelle 20.The position 6 for the operator is in front of a removal area labeled 5. The envelopes 18 to be opened are arranged in a storage chute 7. They are removed from the storage shaft 7 by a suction device on a suction arm 8. It is controlled by a photocell 20.

An diesen Teil schließt sich in Bearbeitungsrichtung die im wesentlichen waagerecht liegende Transportebene mit einem Fördersystem an. Das Schneidwerk ist mit l0 bezeichnet. Die Schneidwerkzeuge sind durch eine Verstellung 29 verstellbar. Auf der Transportebene 9 gelangen die Umschläge nach dem Aufschneiden an der vorderen Umschlagkante in der durch den Pfeil in Fig. l angedeuteten Transporteinrichtung in die eigentliche Entnahmestation l2.In the processing direction, this part is followed by the essentially horizontal transport plane with a conveyor system. The cutting unit is labeled l0. The cutting tools are adjustable by an adjustment 29. On the transport plane 9, the envelopes, after being cut open, reach the actual removal station l2 in the transport device indicated by the arrow in FIG.

Die Entnahmestation wird durch zwei Sauger l5 und l6 gebildet. Der untere Sauger l5, der in der Transportebene 9 liegt, ist an einem schwenkbaren Tischsegment l3 befestigt.The removal station is formed by two suction cups l5 and l6. The lower suction l5, which lies in the transport plane 9, is attached to a pivotable table segment l3.

Der obere Sauger l6 ist an einem Saugarm l7 befestigt.The upper suction l6 is attached to a suction arm l7.

Der Fig. l ist zu entnehmen, daß die Transportebene 9 etwas tiefer liegt als die Entnahmefläche 5, so daß eine Umschlagführungskante ll entsteht.1 that the transport plane 9 is somewhat lower than the removal surface 5, so that a cover guide edge 11 is created.

Für die in Transportrichtung vorne liegende Umschlagkante 28 sind für verschiedene Umschlaggrößen Anschläge l4 vorgesehen.For the envelope edge 28 lying at the front in the transport direction, stops 14 are provided for different envelope sizes.

Eine Fotozelle 20 erfaßt die Entnahme des Umschlaginhaltes l9 und löst dadurch den nächsten Entnahmetakt bzw. Maschinentakt aus.A photocell 20 detects the removal of the envelope content 19 and thereby triggers the next removal cycle or machine cycle.

Dem oberen Sauger l6 liegt ein Kontaktschalter 24 gegenüber. Dem unteren Sauger l5 liegt ein Gegenhalter 25 gegenüber, da die beiden Sauger l5 und l6 in der Umschlagebene gegeneinan­der versetzt sind.A contact switch 24 is located opposite the upper sucker 16. A counter holder 25 is located opposite the lower suction cup l5, since the two suction cups l5 and l6 are offset from one another in the envelope plane.

An dem Tischsegment l3 ist ein Vorsprung 26 angrenzend an den unteren Sauger l5 vorgesehen.A projection 26 is provided on the table segment l3 adjacent to the lower suction cup l5.

Das Tischsegment ist um die Längskante schwenkbar, die parallel zu der Umschlagführungskante ll aber von dieser entfernt liegt. Die vordere Kante des Tischsegmentes wird ungefähr auf die Höhe der Entnahmefläche 5 geschwenkt.The table segment is pivotable about the longitudinal edge, which is parallel to the envelope guide edge 11 but away from it. The front edge of the table segment is pivoted approximately to the height of the removal surface 5.

Im Betrieb werden die mit Hilfe des Saugarmes 8 vereinzelten und durch das Schneidwerk l0 an der Vorderkante geöffneten Briefumschläge l8 durch die Fördereinrichtung in der Transportebene 9 in die Entnahmestation l2 gefördert und zwar bis zum Erreichen des entsprechenden Anschlages l4.l oder l4.2. Diese Stellung ist in Fig. 3 gut erkennbar. Die Fotozelle 22 stellt die Länge des entsprechenden Briefumschlages fest und steuert die Anschläge l4.l oder l4.2.. Der Saugarm l7 mit dem oberen Sauger l6 wird nach Eintreffen des Briefumschlages in die Entnahmestation nach unten auf den Umschlag bewegt. Die entsprechende Endstellung des oberen Saugers l6 wird durch den Kontaktschalter 24 ermittelt, der das Anlegen des Vakuums und die weiteren Bewegungen steuert. Nach dem Anlegen des Vakuums werden das Tischsegment l3 mit dem unteren Sauger und der Saugarm l7 mit dem oberen Sauger l6 gemeinsam hochgeschwenkt, bis die Stellung erreicht ist, die für ein Einsehen der Bedienungs­person in den Umschlag angestrebt wird. Der Saugarm l7 mit dem oberen Sauger l6 setzt seine Bewegung senkrecht zur Umschlagebene fort, um den Umschlag so zu öffnen, wie es in Fig. 4 dargestellt ist. Parallel hierzu führt der Saugarm l7 mit dem oberen Sauger l6 die Bewegung in der Umschlagebene durch, wie es in Fig. 5 dargestellt ist. Diese Bewegung ist eine Kippbewegung um den Kippwinkel 23.In operation, the envelopes l8 separated by means of the suction arm 8 and opened by the cutting unit 10 at the front edge are conveyed into the removal station l2 by the conveying device in the transport plane 9 until the corresponding stop 14.1 or 14.2 is reached. This position is clearly visible in Fig. 3. The photocell 22 determines the length of the corresponding envelope and controls the stops 14.1 or 14.2. The suction arm 17 with the upper suction device 16 is adjusted Arrival of the envelope in the removal station moves down on the envelope. The corresponding end position of the upper suction device 16 is determined by the contact switch 24, which controls the application of the vacuum and the further movements. After the vacuum has been applied, the table segment l3 with the lower suction device and the suction arm l7 with the upper suction device l6 are swiveled up together until the position is reached which is sought for the operator to inspect the envelope. The suction arm 17 with the upper suction device 16 continues its movement perpendicular to the envelope plane in order to open the envelope as shown in FIG. 4. In parallel, the suction arm 17 with the upper suction device 16 carries out the movement in the envelope plane, as shown in FIG. 5. This movement is a tilting movement about the tilt angle 23.

Bei dieser Ausführungsform ist auf dem Tischsegment l3 ein Vorsprung 26 vorgesehen, der angrenzend an den Sauger l5 vorgesehen ist und in diesem Bereich für eine weitere Verwerfung und damit sichere Trennung von Umschlag und Inhalt sorgt.In this embodiment, a projection 26 is provided on the table segment l3, which is provided adjacent to the suction cup l5 and in this area ensures further warping and thus safe separation of the envelope and contents.

Der Bewegungsablauf der Sauger und ihre Wirkung auf den Umschlag l8 und den Inhalt l9 lassen sich deutlich aus den Fig. 4 bis 5 entnehmen. Durch die besondere Schwenkbewegung des oberen Saugers l6 wird die Umschlagkante 28 hochgezogen und dabei der gegebenenfalls mit angesaugte Inhalt von dem Umschlag getrennt. Der Vorsprung 26 unterstützt diese Trennung.The sequence of movements of the suction devices and their effect on the envelope 18 and the contents 19 can be clearly seen in FIGS. 4 to 5. Due to the special pivoting movement of the upper suction device 16, the cover edge 28 is pulled up and the contents which may have been sucked in are separated from the cover. The projection 26 supports this separation.

Die Entleerung des Umschlages wird durch die Fotozelle 20 erfaßt, so daß der nächste Entnahmetakt ausgelöst werden kann. Hierdurch bestimmt die Bedienungsperson die Entnahmegeschwindigkeit selbst.The emptying of the envelope is detected by the photocell 20 so that the next removal cycle can be triggered. In this way, the operator himself determines the removal speed.

Anstelle der Verwendung mehrerer Anschläge l4.l und l4.2 ist es auch möglich, lediglich einen Anschlag l4 vorzusehen, der entsprechend verstellt werden kann.Instead of using several stops 14.1 and 14.2, it is also possible to provide only one stop 14, which can be adjusted accordingly.

Bei einer nicht dargestellten anderen Ausführungsform ist der untere Sauger l5 nicht mit dem Tischsegment l3 fest verbunden, sondern getrennt von diesem senkrecht zur Umschlagebene bewegbar. In diesem Falle ist der Sauger l5 an einem eigenen Saugarm befestigt.In another embodiment, not shown, the lower sucker l5 is not firmly connected to the table segment l3, but can be moved separately from the latter perpendicular to the envelope plane. In this case, the suction cup l5 is attached to its own suction arm.
