Description

Die Erfindung betrifft eine Vorrichtung zur Entsorgung einer Bogendruckmaschine, die einem mittels einer mit Greiferwagen versehenen Transportkette ununterbrochen mit bedruckten Bogen belieferbaren Bogenausleger in Förderrichtung nachgeschaltet ist. Es ist eine Vielzahl von Entsorgungsvorrichtungen von Bogendruckmaschinen bekannt, bei denen die bedruckten Bogen mittels mit Greiferwagen versehenen Transportketten dem Druckwerk entnommen, zu einem Ausleger transportiert und unmittelbar in Form eines Stapels abgespeichert werden.The invention relates to a device for the disposal of a sheet-fed printing press, which is connected in the conveying direction to a sheet delivery that can be continuously supplied with printed sheets by means of a transport chain provided with a gripper carriage. A large number of disposal devices for sheet-fed printing machines are known, in which the printed sheets are removed from the printing unit by means of transport chains provided with gripper carriages, transported to a delivery unit and stored directly in the form of a stack.

Bei ununterbrochener Förderung von Bogen muß mittels Transportplattformen ein ständiger Stapelwechsel vorgenommen werden. Die hohen Maschinengeschwindigkeiten erschweren die erforderliche Ausrichtung des Stapels und erfordern die Verwendung von Hilfsstapelplattformen (DE-PS 33 04 673). Solche Einrichtungen beanspruchen naturgemäß viel Platz. Außerdem tritt bei zunehmendem Gewicht des sich bildenden Stapels das Problem auf, daß die frisch bedruckten Bogen aneinander haften. Durch fortlaufend kleine Stapelbildung unter Zuhilfenahme von einschiebbaren Zwischenplatten, die gegeneinander abgestützt werden müssen, kann man diesem Problem entgegenwirken. Jedoch nimmt man dabei in Kauf, daß die Arbeitsgeschwindigkeit stark verringert wird. Ein weiterer Nachteil der Stapelbildung direkt nach dem Druckprozeß ist darin zu sehen, daß zwar für die Trocknung der Druckbogen Blaseinrichtungen, die beim Stapelwenden im Moment der Senkrechtstellung der Druckbogen von den Seiten her Luft einblasen, einsetzbar sind. Jedoch ist ein befriedigendes Trockenergebnis nicht zu erwarten, da die dazu erforderliche Stapelauflockerung nur in begrenzten Maßen erfolgen kann, so daß der Stapel nicht instabil wird.If sheets are conveyed continuously, a constant stack change must be carried out using transport platforms. The high machine speeds complicate the required alignment of the stack and require the use of auxiliary stacking platforms (DE-PS 33 04 673). Such facilities naturally take up a lot of space. In addition, as the weight of the stack being formed increases, there is a problem that the freshly printed sheets stick to each other. This problem can be counteracted by continuously forming small stacks with the help of insertable intermediate plates that have to be supported against each other. However, it is accepted that the working speed is greatly reduced. Another disadvantage of the stack formation directly after the printing process is that blowing devices which blow air from the sides when the stack is turned at the moment of the vertical positioning of the printed sheets can be used for drying the printed sheets. However, a satisfactory drying result is not to be expected, since the stack loosening required for this can only take place to a limited extent, so that the stack does not become unstable.

Aufgabe der Erfindung ist es, eine Vorrichtung zur Entsorgung einer Bogendruckmaschine zu schaffen, die eine Speichermöglichkeit anbietet, bei der die Speicherung auf reduziertem Raum erfolgen kann, ohne daß eine Haftung der frisch bedruckten Bogen aneinander auftritt und es erlaubt, die Bogen ohne Umspeicherung bzw. Stapelbildung weiteren Verarbeitungsprozeßen, wie z.B. dem Trocknungsprozeß zuzuführen.The object of the invention is to provide a device for the disposal of a sheet-fed printing machine which offers a storage option in which the storage can take place in a reduced space without the freshly printed sheets adhering to one another and allowing the sheets to be stored without being stored or Batch formation of further processing processes, such as to supply the drying process.

Fig. 1 zeigt ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung im Zusammenhang mit einer Bogendruckmaschine, die die Druckeinheiten 1 bis 3 umfaßt. In Förderrichtung nach der Druckeinheit 3 ist in bekannter Weise eine mit Greiferwagen 4 versehene endlos geführte Antriebskette 5 vorgesehen, mittels dieser Druckbogen 6 der Druckmaschine entnehmbar und zu einem Ausleger 7 transportierbar sind (siehe auch Fig. 2). Über Walzen 8, 9 endlos geführte Saugbänder 10, die mit einer Gleitfläche 11, die eine taktmäßig angetriebene Nockenwalze 30 aufweist, zusammenwirken, stellen die Verbindung zu einer die Druckbogen 6 aufnehmenden Speichereinrichtung in Form einer Taschenstruktur 12 her.Fig. 1 shows an embodiment of the device according to the invention in connection with a sheet-fed printing press, which comprises the printing units 1 to 3. In the conveying direction after the printing unit 3, an endlessly guided drive chain 5 provided with a gripper carriage 4 is provided, by means of which printing sheets 6 can be removed from the printing press and transported to a delivery unit 7 (see also FIG. 2). Suction belts 10, which are guided endlessly via rollers 8, 9 and which cooperate with a sliding surface 11, which has a cyclically driven cam roller 30, establish the connection to a storage device receiving the printed sheets 6 in the form of a pocket structure 12.

Eine Vielzahl von Ausgestaltungsmöglichkeiten einer Taschenstruktur 12 ist in der DE-PS 36 21 832 ausführlich beschrieben. Die bevorzugte Ausbildung der Taschenstruktur 12, wie sie im Ausführungsbeispiel verwendet wird, weist seitlich an Schienen 13, 14 geführte Segmente 15 in Form von elastischen Blechen 16, 17 auf, die jeweils miteinander über elastische, an ihren Berührungsstellen V-förmig verbundenen Stege 18, 19 verbunden, beispielsweise verschweißt sind. Es versteht sich, daß die Segmente 15 sich beliebig oft aneinanderreihen lassen, um eine ausreichend lange endliche Taschenstruktur 12 zu bilden, wobei jedes Segment 15 fächerförmig auseinanderzieh- bzw. zusammenschiebbar ist. Um eine Beabstandung der Bleche 16, 17 eines Segmentes 15 in geschlossenem Zustand zu erreichen, ist auf der Innenseite eines der Bleche 16 jeweils ein Blättchen 20 angebracht. Ein solches auseinandergezogenes Segment 15 ist in Fig. 4 gezeigt.A variety of design options for a pocket structure 12 is described in detail in DE-PS 36 21 832. The preferred embodiment of the pocket structure 12, as used in the exemplary embodiment, has segments 15 guided laterally on rails 13, 14 in the form of elastic sheets 16, 17, each of which is connected to one another via elastic webs 18 connected in a V-shape at their points of contact, 19 connected, for example welded. It goes without saying that the segments 15 can be strung together as often as desired to form a sufficiently long finite pocket structure 12, each segment 15 being able to be pulled apart or pushed together in a fan shape. In order to achieve a spacing of the sheets 16, 17 of a segment 15 in the closed state, a sheet 20 is attached to the inside of one of the sheets 16. Such an extended segment 15 is shown in FIG. 4.

Die Taschenstruktur 12 weist eine geteilte Form auf, bei der die Segmente 15 jeweils paarweise beidseitig der aufzunehmenden Bogen 6 mit den Schienen 13, 14, die mit Aussparungen 21, 22 der Bleche 16, 17, die auf die Schienen 13, 14 gehängt sind, zusammenwirken, geführt sind (siehe Fig. 6 und 7). Eine gleichbleibende Anzahl von derartigen Segmenten 15 ist zu einem Taschenpaket 23 zusammengefaßt.The pocket structure 12 has a divided shape, in which the segments 15 are in pairs on both sides of the sheet 6 to be received with the rails 13, 14, which have recesses 21, 22 of the sheets 16, 17 which are hung on the rails 13, 14. interact, are guided (see Fig. 6 and 7). A constant number of such segments 15 is combined to form a pocket package 23.

Fig. 2 zeigt einen Ladebereich 24 mit einer aufgefächterten Taschenstruktur 12. Der Ladebereich 24 ist mittels einer Transportkette 25 mit einer Speichereinheit in Form einer Speicherkassette 26, wie sie in der europäischen Patentanmeldung EP-0 336 177 der gleichen Anmelderin beschrieben ist, in der leere Taschenpakete 23 lagern, verbunden. Jeweils parallel zu den die Segmente 15 führenden Schienen 13, 14 des Ladebereiches 24 sind über denselben jeweils mit Mitnehmern 27 versehenen Antriebsketten 28, 29 endlos geführt (siehe Fig. 3 und 6).2 shows a loading area 24 with a fanned-out pocket structure 12. The loading area 24 is empty by means of a transport chain 25 with a storage unit in the form of a storage cassette 26, as described in European patent application EP-0 336 177 by the same applicant Store bag packs 23, connected. In each case parallel to the rails 13, 14 of the loading area 24, which guide the segments 15, drive chains 28, 29, each provided with carriers 27, are endlessly guided (see FIGS. 3 and 6).

Die ununterbrochen geförderten bedruckten Bogen 6 werden vom Ausleger 7 mittels der Saugbänder 10 auf die Gleitfläche 11 befördert. Ein zuvor aus der Speicherkassette 26 zum Ladebereich 24 transportiertes Taschenpaket 23 wird von der Transportkette 25 im Ladebereich 24 an das vorauslaufende, bereits teilweise aufgefächerte angekoppelt, so daß die Mitnehmer 27 der Antriebsketten 28, 29 in die Segmente 15 der Taschenstruktur 12 eingreifen, sie in Richtung des Pfeiles 31 ziehen und die Segmente 15 dabei fächerförmig öffnen können. Die auf der Gleitfläche 11 ankommenden Bogen 6 werden nun taktmäßig jeweils einzeln in ein Segment 15 gesteckt, so daß die in den fächerförmig geöffneten Segmenten 15 steckenden bedruckten Bogen 6 durch die Bleche 16, 17 jeweils voneinander beabstandet sind, wobei die Nockenwalze 30 diesen Vorgang in der Weise unterstützt, daß sie im Moment des Eindringens des Folgebogens das Ende des vorauslaufenden Bogens anhebt. Es ist aber auch möglich, auf einfache Weise wahlweise einzelne Probebogen wieder den Segmenten 15 zu entnehmen.The continuously conveyed printed sheets 6 are conveyed from the delivery 7 onto the sliding surface 11 by means of the suction belts 10. A pocket packet 23 previously transported from the storage cassette 26 to the loading area 24 is coupled by the transport chain 25 in the loading area 24 to the preceding, already partially fanned out, so that the drivers 27 of the drive chains 28, 29 engage in the segments 15 of the pocket structure 12, they in Pull in the direction of arrow 31 and the segments 15 can open in a fan shape. The arriving on the sliding surface 11 sheets 6 are now inserted individually into a segment 15, so that the printed sheets 6 inserted in the fan-shaped segments 15 are spaced apart by the sheets 16, 17, the cam roller 30 in this process which helps to lift the end of the leading sheet at the moment the following sheet penetrates. However, it is also possible to remove individual sample sheets from the segments 15 in a simple manner.

Sobald ein Taschenpaket 23 mit Druckbogen 6 belegt und zu einem vollen Taschenpaket 36 zusammengeschoben ist, wird es mittels Ketten 32 vom Ladebereich 24 entkoppelt und über diese Ketten 32 einer Speicherkassette 26 zugeführt, die ebenfalls Schienen 45, 46 enthält und die dieselbe wie die, aus der die leeren Taschenpakete 23 geholt werden, sein kann. Die Art und Weise der An- und Entkopplung ist in der europäischen Patentanmeldung 0 336 177 ausführlich beschrieben. Die Segmente 15 der Taschenstruktur 12 bleiben also immer auf Schienen 13, 14, 45, 46 geführt.As soon as a pocket packet 23 is filled with printed sheets 6 and pushed together to form a full pocket packet 36, it is decoupled from the loading area 24 by means of chains 32 and fed via these chains 32 to a storage cassette 26 which also contains rails 45, 46 and which are the same as those which can be fetched the empty bag packs 23. The manner of coupling and decoupling is described in detail in European patent application 0 336 177. The segments 15 of the pocket structure 12 thus always remain on rails 13, 14, 45, 46.

Noch während die beladene Taschenstruktur 12 zu einem vollen Taschenpaket 36 zusammengeschoben wird, wird schon ein neues Taschenpaket 23 aufgefächert, so daß keine zeitliche Unterbrechung des Ladevorganges, bzw. ein Rückstau der ununterbrochen geförderten Druckbogen 6 entsteht. Ein weiterer Vorteil eines derartigen Bogentransports besteht offensichtlich darin, daß eine Flächenbelastung senkrecht zur Papierfläche nicht auftritt.Even while the loaded bag structure 12 is pushed together to form a full bag packet 36, a new bag packet 23 is already fanned out, so that there is no interruption in the loading process or a backlog of the continuously conveyed printed sheets 6. Another advantage of such a sheet transport is obviously that there is no surface load perpendicular to the paper surface.

Fig. 5 zeigt ein geschlossenes Segment 15 mit einem zwischen die Bleche 16, 17 eingesteckten Druckbogen 6. Das Blättchen 20 auf der Innenseite des Bleches 16 vermindert die Berührungsfläche zwischen einem Blech 16 und der bedruckten Seite des Druckbogens 6, da es in der Weise auf der Innenseite des Bleches 16 angebracht ist, so daß es nur den unbedruckten Rand des Bogens 6 berührt.5 shows a closed segment 15 with a printed sheet 6 inserted between the sheets 16, 17. The leaflet 20 on the inside of the sheet 16 reduces the contact area between a sheet 16 and the printed side of the printed sheet 6, since it is in such a way the inside of the sheet 16 is attached so that it only touches the unprinted edge of the sheet 6.

Die mit beladenen Taschenpaketen 36 gefüllte Speicherkassette 26 mit den die Taschenpakete tragenden Schienen 45, 46 kann nun in bekannter Weise mittels weiteren, aus Übersichtlichkeitsgründen nicht gezeigten Transportmitteln weiteren Weiterverarbeitungsstationen zugeführt werden. Wie in Fig. 1 gezeigt ist, ist es relativ leicht möglich, in einem Pufferspeicher 33, in dem mehrere Speicherkassetten 26 gesammelt werden, mittels einer unterhalb des Pufferspeichers 33 angeordneten Luftleitung 34 den locker in den nach unten offenen Taschenpaketen 36 steckenden Bogen 6 Blasluft zuzuführen und somit einen befriedigenden Trocknungsprozeß durchzuführen.The storage cassette 26 filled with loaded bag packs 36 with the rails 45, 46 carrying the bag packs can now be fed to further processing stations in a known manner by means of further transport means, not shown for reasons of clarity. As is shown in FIG. 1, it is relatively easy to supply blowing air to the sheet 6, which is loosely inserted in the pocket packs 36 that are open at the bottom, in a buffer store 33, in which a plurality of storage cartridges 26 are collected, by means of an air line 34 arranged below the buffer store 33 and thus perform a satisfactory drying process.

Danach oder unabhängig davon sind die Druckbogen 6 einer beladenen Speicherkassette 26, wie ebenfalls in Fig. 1 gezeigt ist, durch Umkehrung des Ladeprozesses der Taschenpakete 23 im Ladebereich 24 über einen Entladebereich 35 den Druckwerken 1 bis 3 zwecks des Bedruckens der anderen Bogenseite erneut zuführbar. Dazu werden die beladenen Taschenpakete 36 über eine Transportkette 37 den Schienen 38, 39 des Entladebereiches 35 zugeführt und hier aneinandergekoppelt wieder in schon beschriebener Weise mittels einer Antriebskette 43 aufgefächert, die Bogen 6 in bekannter Weise den Segmenten 15 entnommen und dem Druckprozeß erneut zugeführt. Die entleerten Taschenpakete 23 werden danach über eine Transportkette 41 wieder in eine Speicherkassette 26 überführt. Diese Verarbeitungschritte können also ohne Stapelbildung erfolgen.Thereafter or independently of this, the printed sheets 6 of a loaded storage cassette 26, as also shown in FIG. 1, can be fed again to the printing units 1 to 3 for the purpose of printing on the other sheet side by reversing the loading process of the pocket packs 23 in the loading area 24 via an unloading area 35. For this purpose, the loaded bag packs 36 are fed to the rails 38, 39 of the unloading area 35 via a transport chain 37 and, coupled here, are fanned out again in the manner already described by means of a drive chain 43, the sheets 6 in a known manner removed from the segments 15 and fed back to the printing process. The emptied bag packs 23 are then transferred back to a storage cassette 26 via a transport chain 41. These processing steps can therefore be carried out without stack formation.

Jedoch können die Druckbogen 6 der beladenen Taschenpakete 36 unter Auslenkung der die Taschenstrukturen 12 führenden Schienen 51, 52, bei gleichzeitiger Auffächerung der Segmente 15 mittels einer mit Mitnehmer versehenen Antriebskette 53 auch einer Abstapelung zugeführt werden. Der Abstand der Schienen 51, 52 im Bereich der Übergabestelle ist so vergrößert, daß die Bogen 6 zwischen den seitlich angeordneten Segmenten 15 hindurchfallen und sich in Form eines Stapels 42 sammeln (siehe Fig. 8 und 9). Die leeren zweigeteilten Taschenpakete 23 sind seitlich des Stapels 42 abführbar und dem gesamten System wieder zuführbar.However, the printed sheets 6 of the loaded bag packs 36 can also be stacked by deflecting the rails 51, 52 guiding the bag structures 12 while simultaneously fanning out the segments 15 by means of a drive chain 53 provided with a driver. The distance between the rails 51, 52 in the area of the transfer point is increased so that the sheets 6 fall through between the laterally arranged segments 15 and collect in the form of a stack 42 (see FIGS. 8 and 9). The empty, two-part pocket packs 23 can be removed from the side of the stack 42 and can be fed back to the entire system.

  6. Device according to claim 5, characterised in that parallel to the rails (13, 14) guiding the pocket structure (12), drive chains (28, 29) provided with entrainers (27) are arranged in such a way that the entrainers (27) engage into the segments (15) of the pocket structure (12) and can pull them apart or push them together.
  7. Device according to one of the preceding claims, characterised in that to load the pocket structure (12) with the printed sheets (6) from the delivery device (7) in the loading area (24) suction belts (10) are provided which co-operate with at least one sliding surface (11) in such a way that a synchronised insertion of the sheets (6) into the segments (15) of the pocket structure (12) is possible.
  8. Device according to claim 7, characterised in that the sliding surface (11) which can be supplied with sheets (6) by means of the suction belts (10) cooperates with a cam roller (30) in such a way that just as the following sheet penetrates into a segment (15) the end of the preceding sheet is lifted.
  9. Device according to claim 5, characterised in that in the loading area (24) whilst a loaded pocket structure (12) is being pushed together to form a full stack of pockets (36) a new stack of pockets (23) can be spread out in direct succession.
  10. Device according to claim 3, characterised in that at least one storage unit (26) can be conveyed to a buffer store (33) in which blast air can be conveyed by means of an air line (34) arranged below the buffer store (33) to the sheets (6) placed in the stacks of pockets (36).
  11. Device according to claim 3, characterised in that the stacks of packets (36) can be conveyed to an unloading region (35) in which the sheets (6) can be removed by reversal of the loading procedure of the pocket structure (12) for the purpose of printing the other side of the sheet, and can be conveyed again to the printing units (1 to 3).
  12. Device according to claim 3, characterised in that the sheets (6) stored in the stacks of pockets (36) can optionally be unstacked with disengagement of the rails (52, 52) guiding the pocket structure (12) with simultaneous fanning out of the segments (15).
  13. Device according to claim 2, characterised in that the segments (15) are made of resilient sheets (16, 17) which are each joined to each other by means of elastic crosspieces (18, 19) which are V-shaped at their points of contact, and in that respectively one of the sheets (16, 17) forming the segments (15) has a small plate (20) which presses on the unprinted edge of a sheet (6) when the segments (15) are pushed together and hence spaces the printed surface from the sheet (16 or 17).
