Definitions
- the invention relates to a pocket folding machine according to the preamble of claim 1.
- Pocket folding machines and Schwertfalzmaschinen are known from the prior art.
- the combination of pocket folding machines with Schwertfalzmaschinen is common as Kombifalzmaschine.
- parallel folds are folded in pocket folders and cross breaks in the subsequent knife folders.
- the sheet passes through at least the following stations in the feed-through direction of the combination folding machine: feeder, transfer table, pocket folder, knife folder, delivery arm.
- a respective pocket folder consists of a folding pocket and three folding rollers, which are arranged in two pairs of folding rollers.
- From the DE 29 40 360 A1 is a single sword folding machine for folding of printed and pre-folded sheet known.
- Combination folding machines combine pocket folders and knife folders. Here are folded in a first folding station in Taschenfalztechniken parallel breaks and in a subsequent folding station in Schwertfalztechniken cross breaks.
- the DE 31 47 064 A1 and the DE 10 2006 055 301 A1 show Kombifalzmaschinen with a plurality of Taschenfalzwerken and nachranging arranged Schwertfalzwerken.
- the EP 1 970 132 B1 shows a pressing station with a device for cleaning rollers, which may be downstream of a folding station. Using conveyor belts, folded signatures are transferred from a folding station to the pressing station.
- the pressing force is often applied by means acting on the press rollers spring assemblies. If now the distance of the press rolls to be adapted to adapt to products of other thickness, at least one of the press rolls must be adjusted against the force of the spring packs. This requires high forces.
- Object of the present invention is to provide a pocket folding machine, which allows the generation of a variety of signatures in high quality. So both very small and compact signatures as well as very thick signatures should be reliable can be processed. Another task is to improve the pressure of the signatures regardless of the nature of the signature.
- the pocket folding machine which serves for the folding of sheets, in particular of paper, cardboard, cardboard or plastic for signatures, has at least one pocket folding station with at least one folding unit and with at least one pressing unit for pressing off the signatures.
- the at least one folding unit has at least one folding pocket and, associated with a respective folding pocket, a pair of folding rollers.
- At least one of the pressing plants is arranged downstream of the at least one folding unit.
- the pressing plant is arranged directly downstream of a last pair of folding rollers, viewed in the direction of transport of the sheets. That is, between the last pair of folding rollers and the press shop, there are no other means of transport.
- the folding rollers of the at least one folding unit and the press rollers of the press shop are mounted in a common Falzwalzenstuhl, wherein the Falzwalzenstuhl has two mutually parallel side walls as bearing plates.
- a pocket folding machine has the advantages that short and multiple folded products can be pressed immediately before they are transported in the machine. This prevents the products from opening during further transport. Because the products remain closed after being pressed off, they can subsequently be transported further at a lower speed without affecting the folding quality.
- the folding rollers and the press rollers are driven in rotation by a common drive, in particular a controllable electric motor.
- the press shop is designed as a belt press with two, a press nip forming press rolls and two, a respective press roll encircling circulating conveyor belts.
- an auxiliary roller is arranged upstream and downstream, as viewed in the transport direction, of a respective press roller.
- a respective press roll and the two associated auxiliary rolls are in each case wrapped around by a circulating conveyor belt. It is considered to be particularly advantageous that the vertical distance between the two auxiliary rollers arranged upstream is greater than the vertical distance between the two press rollers. This results in a taper of the conveying gap between the circulating conveyor belts. This causes the products in the press shop to undergo pre-pressing before the actual pressing operation takes place between the press roller pair. The pressing force of the pre-pressing increases from the inlet area at the auxiliary rollers to the press roller pair so that air can be squeezed out between the folded sides of a respective product.
- the press shop has at least one pneumatic cylinder for acting on the press rolls with a pressing force.
- an adjusting device is assigned to adjust the distance of the two press rolls. It is considered particularly advantageous if this adjusting device has a controllable electromotive drive.
- the adjusting device acts in particular on at least one bearing of one of the press rolls and thus effects a distance adjustment between the two press rolls.
- the controllable electromotive drive can be connected to a machine control of the pocket folding machine, so that the press roller distance can be easily adjusted and already derived from the order data.
- the press shop seen in the transport direction - at least one pair of knife shafts for processing the folded and pressed-off signatures and / or another folding station, namely a Taschenfalzstation or a Schwertfalzstation, downstream.
- FIG. 1 shows a pocket folding machine 100 according to the prior art.
- a sheet 1000 passes from a feeder 1 coming a Taschenfalzstation 3, is folded and then passes through a spatially spaced pressing station 5, in which the folded sheet 1000, ie the signature 1001, is pressed, and subsequently further folding stations before the signature 1001 in a boom 2 is designed.
- the Taschenfalzstation 3 has a plurality of folding units, wherein a respective folding unit has at least one folding pocket 3.1 and a pair of folding rollers 3.2. Preceded by the first folding unit - viewed in the transporting direction T - there can be a pair of knife shafts 4.
- a respective sheet 1000 is prepared for the subsequent folding process, for example by creasing, cutting and / or perforating.
- a pair of knife shaft 4.2 may be downstream, in which the folded sheet 1000 is reworked, for example, by receiving a separating cut or trimming.
- the folded sheet 1000 is subsequently transferred to conveyor belts or transport tables, which transport the folded sheet 1000 to a press roller pair where the folded sheet 1000 undergoes a pressing.
- the conveyor belts or transport tables of the folded sheet 1000 must be transported as quickly as possible to the press rollers of the pressing station 5 in order to avoid opening the sides of the folded sheet 1000.
- FIG. 2 a pocket folding machine 100 according to the invention is shown. Like the pocket folding machine 100 according to the prior art, this has a Taschenfalzstation 3 with a plurality of folding units, wherein a respective folding unit has at least one folding pocket 3.1 and associated with a pair of folding rollers 3.2. In contrast to the machine according to the prior art, no pressing station 5 is provided. Instead, a belt press 10 was integrated as a press shop in the Taschenfalzstation 3. The belt press 10 joins - seen in the transport direction T - directly to the last pair of folding rollers 3.2. That is, between the last folding rollers 3.2 and the belt press 10 no further means of transport are provided. Preceded by the folding units, a pair of knife shafts 4.
- Downstream of the belt press 10 can also be provided a pair of knife shafts 4.2. Both the folding rollers 3.2 and the rollers 11, 13, 14, 16 of the belt press 10 and possibly also the upstream cutter shaft pair 4.1 and the downstream cutter shaft pair 4.2 are mounted together in the folding roller 19.
- the press rollers 11, 14 and thus also the conveyor belts 12, 15 and the folding rollers 3.2 and optionally also the cutter shafts 4.1 and 4.2 can be driven by a common drive (not shown) rotatably.
- the downstream auxiliary rollers 13 and 16 can be moved further in the transport direction, so that the conveyor belts 12, 15 allow the further transport of short signatures 1001 to a subsequent processing station (not shown) without the Open signatures 1001.
- the lower press roller 14 perform a feed movement Z.
- the lower pressure roller 14 is connected to a pneumatic cylinder 17, which can build up the pressing force F.
- the belt press 10 further has an adjusting device 18 with a motor-adjustable stop, which can undergo an adjustment a. If a change in the distance between the two press rolls 11, 14 take place, the pressing force F generated by the pneumatic cylinder 17 is reduced and the adjustable stop of the setting device 18 is displaced. Since the adjustment does not take place against the high pressing force F, a controllable electric motor drive of small power is sufficient for actuating the adjusting device 18. As in FIG.
- the pneumatic cylinder 17 has been deactivated, ie the pressing force F degraded, and adjusts the stop of the adjuster 18. After adjustment a of the stop of the adjustment 18 of the pneumatic cylinder 17 is activated again and the pressing force F built.
- the pneumatic cylinder 17 and the adjusting device 18 can be controlled by a common machine control (not shown).

- a pair of knife shafts 4. 1 can be arranged. Downstream of the roll press 10 may also be provided a pair of knife shafts 4.2.
- Both the folding rollers 3.2 and the rollers 11, 14 of the roller press 10 and possibly also the upstream cutter shaft pair 4.1 and the downstream cutter shaft pair 4.2 are stored together in the folding roller 19.
- the press rollers 11, 14 and the folding rollers 3.2 and optionally also the cutter shafts 4.1 and 4.2 can be driven in rotation by a common drive (not shown).
- Fig. 4b an alternative embodiment of a pocket folding station 3 is shown.
- the upstream cutter shafts 4.1 is also a pressing station 10.
- Such a design is considered advantageous if it is at the Taschenfalzstation 3 is a second Taschenfalzstation, ie if between the feeder 1 and 3 Taschenfalzstation yet another Taschenfalzstation 3 is arranged.
- the already folded in the first folding station 3 signatures 1001 can be pressed before re-folding, whereby a higher folding accuracy is achieved.
- the signatures 1001 by 90 ° redirecting transport table is used (not shown), in an embodiment of the first Taschenfalzstation 3 according to Fig.

Description
Die Erfindung betrifft eine Taschenfalzmaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to a pocket folding machine according to the preamble of
Aus dem Stand der Technik sind Taschenfalzmaschinen und Schwertfalzmaschinen bekannt. Die Kombination von Taschenfalzmaschinen mit Schwertfalzmaschinen ist als Kombifalzmaschine geläufig. Dabei werden in Taschenfalzwerken Parallelbrüche und in den nachfolgenden Schwertfalzwerken Kreuzbrüche gefalzt. Der Bogen durchläuft dabei in Durchlaufrichtung der Kombifalzmaschine mindestens folgende Stationen: Anleger, Übergabetisch, Taschenfalzwerk, Schwertfalzwerk, Ausleger.Pocket folding machines and Schwertfalzmaschinen are known from the prior art. The combination of pocket folding machines with Schwertfalzmaschinen is common as Kombifalzmaschine. In this process, parallel folds are folded in pocket folders and cross breaks in the subsequent knife folders. The sheet passes through at least the following stations in the feed-through direction of the combination folding machine: feeder, transfer table, pocket folder, knife folder, delivery arm.
Der Aufbau einer Taschenfalzmaschine mit einer Vielzahl von Taschenfalzwerken geht aus der
Auch bekannt sind Vorrichtungen zum Pressen und Transportieren von Bogen aus Papier, Pappe und dergleichen, wie z. B. Prospekte, Zeitschriften, Flyer, welche dazu dienen, die Produkte so zu pressen, dass diese für den Weitertransport mit einer hohen Packungsdichte aufeinander gestapelt werden können, da durch das Pressen kompakte und gleichmäßige Stapel möglich sind.Also known are devices for pressing and transporting sheets of paper, cardboard and the like, such as. As brochures, magazines, flyers, which serve to press the products so that they can be stacked on each other for further transport with a high packing density, as compact and uniform stacks are possible by pressing.
Insbesondere bei gefalzten Druckweiterverarbeitungsprodukten, sogenannten Signaturen, wird zwischen den Seiten Luft eingeschlossen. Diese Luft wird durch das Pressen der Produkte herausgepresst. Weiter werden durch das Pressen bereits gebrochene, aber noch nicht vollständig gefalzte Falzkanten sauber gefalzt, was insbesondere bei dicken und steifen Materialien die Qualität der Falzkante erhöht.Especially with folded print finishing products, so-called signatures, air is trapped between the pages. This air is squeezed out by pressing the products. Further, by pressing already broken, but not yet fully folded folded edges are neatly folded, which increases the quality of the folded edge, especially for thick and stiff materials.

Nachteilig an derartigen Pressstationen ist, dass sich die Produkte nach dem Falzen und während dem Weitertransport zu nachgelagerten Messerwellen, einer nachgelagerten Pressstation und dann zu einer Produktauslage bereits wieder öffnen können. Dies kann zu Materialstau und in Konsequenz zu einem Maschinenstopp führen. Die Gefahr hierfür ist besonders gegeben bei vielfach gefalzten, kleinen Produkten, wie beispielsweise Beipackzetteln oder sogenannten Outserts.A disadvantage of such pressing stations that the products can open again after folding and during further transport to downstream knife shafts, a downstream pressing station and then to a product display. This can lead to material jams and consequently to a machine stop. The danger for this is particularly given in many folded, small products, such as leaflets or so-called outserts.
Bei Pressstationen nach dem Stand der Technik wird die Presskraft häufig mittels auf die Presswalzen wirkenden Federpaketen aufgebracht. Soll nun der Abstand der Presswalzen zur Anpassung an Produkte anderer Dicke angepasst werden, so muss zumindest eine der Presswalzen gegen die Kraft der Federpakete verstellt werden. Dazu sind hohe Kräfte erforderlich.In pressing stations according to the prior art, the pressing force is often applied by means acting on the press rollers spring assemblies. If now the distance of the press rolls to be adapted to adapt to products of other thickness, at least one of the press rolls must be adjusted against the force of the spring packs. This requires high forces.
Aufgabe der vorliegenden Erfindung ist es, eine Taschenfalzmaschine zu schaffen, welche die Erzeugung von unterschiedlichsten Signaturen in hoher Qualität ermöglicht. So sollen sowohl sehr kleine und kompakte Signaturen als auch sehr dicke Signaturen zuverlässig verarbeitet werden können. Weitere Aufgabe dabei ist es, die Pressung der Signaturen unabhängig von der Beschaffenheit der Signatur zu verbessern.Object of the present invention is to provide a pocket folding machine, which allows the generation of a variety of signatures in high quality. So both very small and compact signatures as well as very thick signatures should be reliable can be processed. Another task is to improve the pressure of the signatures regardless of the nature of the signature.
Gelöst wird diese Aufgabe durch eine Taschenfalzmaschine mit den Merkmalen von Anspruch 1.This problem is solved by a pocket folding machine having the features of
Die erfindungsgemäße Taschenfalzmaschine, welche dem Falzen von Bogen, insbesondere aus Papier, Karton, Pappe oder Kunststoff für Signaturen dient, besitzt mindestens eine Taschenfalzstation mit mindestens einem Falzwerk und mit mindestens einem Presswerk zum Abpressen der Signaturen. Das mindestens eine Falzwerk weist mindestens eine Falztasche und, einer jeweiligen Falztasche zugeordnet, ein Paar Falzwalzen auf. Zumindest eines der Presswerke ist dem mindestens einen Falzwerk nachgeordnet. Erfindungsgemäß ist das Presswerk einem - in Transportrichtung der Bogen gesehen - letzten Paar von Falzwalzen unmittelbar nachgeordnet. Das heißt, zwischen dem letzten Falzwalzenpaar und dem Presswerk gibt es keine weiteren Transportmittel. Dabei sind die Falzwalzen des mindestens einen Falzwerks und die Presswalzen des Presswerks in einem gemeinsamen Falzwalzenstuhl gelagert, wobei der Falzwalzenstuhl zwei parallel zueinander angeordnete Seitenwände als Lagerplatten besitzt. Eine derartige Taschenfalzmaschine hat die Vorteile, dass kurze und vielfach gefalzte Produkte sofort abgepresst werden können, bevor sie in der Maschine weitertransportiert werden. Dadurch wird verhindert, dass sich die Produkte während des Weitertransportes öffnen. Weil die Produkte nach dem Abpressen geschlossen bleiben, können diese nachfolgend auch mit geringerer Geschwindigkeit weitertransportiert werden, ohne dass die Falzqualität beeinträchtigt wird.The pocket folding machine according to the invention, which serves for the folding of sheets, in particular of paper, cardboard, cardboard or plastic for signatures, has at least one pocket folding station with at least one folding unit and with at least one pressing unit for pressing off the signatures. The at least one folding unit has at least one folding pocket and, associated with a respective folding pocket, a pair of folding rollers. At least one of the pressing plants is arranged downstream of the at least one folding unit. According to the invention, the pressing plant is arranged directly downstream of a last pair of folding rollers, viewed in the direction of transport of the sheets. That is, between the last pair of folding rollers and the press shop, there are no other means of transport. The folding rollers of the at least one folding unit and the press rollers of the press shop are mounted in a common Falzwalzenstuhl, wherein the Falzwalzenstuhl has two mutually parallel side walls as bearing plates. Such a pocket folding machine has the advantages that short and multiple folded products can be pressed immediately before they are transported in the machine. This prevents the products from opening during further transport. Because the products remain closed after being pressed off, they can subsequently be transported further at a lower speed without affecting the folding quality.
In vorteilhafter Weiterbildung der erfindungsgemäßen Taschenfalzmaschine werden die Falzwalzen und die Presswalzen von einem gemeinsamen Antrieb, insbesondere einem steuerbaren Elektromotor, rotativ angetrieben.In an advantageous development of the pocket folding machine according to the invention, the folding rollers and the press rollers are driven in rotation by a common drive, in particular a controllable electric motor.
In einer Ausführungsvariante ist das Presswerk als Bandpresse ausgeführt mit zwei, einen Pressspalt bildenden Presswalzen und zwei, eine jeweilige Presswalze umschlingenden umlaufenden Transportbändern.In one embodiment, the press shop is designed as a belt press with two, a press nip forming press rolls and two, a respective press roll encircling circulating conveyor belts.
In Weiterbildung der Taschenfalzmaschine ist stromaufwärtig und stromabwärtig - in Transportrichtung gesehen - einer jeweiligen Presswalze je eine Hilfswalze angeordnet. Eine jeweilige Presswalze und die beiden zugeordneten Hilfswalzen werden dabei jeweils von einem umlaufenden Transportband umschlungen. Als besonders vorteilhaft wird es angesehen, dass der vertikale Abstand zwischen den beiden stromaufwärtig angeordneten Hilfswalzen größer ist als der vertikale Abstand zwischen den beiden Presswalzen. Dadurch ergibt sich eine Verjüngung des Förderspaltes zwischen den umlaufenden Transportbändern. Dieser bewirkt, dass die Produkte in dem Presswerk eine Vorpressung erfahren, bevor der eigentliche Pressvorgang zwischen dem Presswalzenpaar erfolgt. Die Presskraft der Vorpressung nimmt vom Einlaufbereich bei den Hilfswalzen bis hin zum Presswalzenpaar zu, so dass Luft zwischen den gefalteten Seiten eines jeweiligen Produktes herausgepresst werden kann.In a further development of the pocket folding machine, an auxiliary roller is arranged upstream and downstream, as viewed in the transport direction, of a respective press roller. A respective press roll and the two associated auxiliary rolls are in each case wrapped around by a circulating conveyor belt. It is considered to be particularly advantageous that the vertical distance between the two auxiliary rollers arranged upstream is greater than the vertical distance between the two press rollers. This results in a taper of the conveying gap between the circulating conveyor belts. This causes the products in the press shop to undergo pre-pressing before the actual pressing operation takes place between the press roller pair. The pressing force of the pre-pressing increases from the inlet area at the auxiliary rollers to the press roller pair so that air can be squeezed out between the folded sides of a respective product.
In einer vorteilhaften Ausgestaltung der Taschenfalzmaschine besitzt das Presswerk mindestens einen pneumatischen Zylinder zum Beaufschlagen der Presswalzen mit einer Presskraft.In an advantageous embodiment of the Taschenfalzmaschine the press shop has at least one pneumatic cylinder for acting on the press rolls with a pressing force.
In vorteilhafter Weiterbildung der Taschenfalzmaschine ist den Presswalzen des Presswerks eine Verstelleinrichtung zugeordnet zur Anpassung des Abstandes der beiden Presswalzen. Als besonders vorteilhaft wird es angesehen, wenn diese Verstelleinrichtung über einen steuerbaren elektromotorischen Antrieb verfügt. Die Verstelleinrichtung wirkt insbesondere auf zumindest ein Lager einer der Presswalzen ein und bewirkt so eine Abstandseinstellung zwischen beiden Presswalzen. Der steuerbare elektromotorische Antrieb kann mit einer Maschinensteuerung der Taschenfalzmaschine verbunden sein, so dass der Presswalzenabstand einfach eingestellt und bereits aus den Auftragsdaten abgeleitet werden kann.In an advantageous embodiment of the Taschenfalzmaschine the press rollers of the press shop an adjusting device is assigned to adjust the distance of the two press rolls. It is considered particularly advantageous if this adjusting device has a controllable electromotive drive. The adjusting device acts in particular on at least one bearing of one of the press rolls and thus effects a distance adjustment between the two press rolls. The controllable electromotive drive can be connected to a machine control of the pocket folding machine, so that the press roller distance can be easily adjusted and already derived from the order data.
In einer Weiterentwicklung der beschriebenen Taschenfalzmaschine sind dem Presswerk - in Transportrichtung gesehen - mindestens ein Messerwellenpaar zur Bearbeitung der gefalzten und abgepressten Signaturen und/oder eine weitere Falzstation, nämlich eine Taschenfalzstation oder eine Schwertfalzstation , nachgelagert.In a further development of the Taschenfalzmaschine described are the press shop - seen in the transport direction - at least one pair of knife shafts for processing the folded and pressed-off signatures and / or another folding station, namely a Taschenfalzstation or a Schwertfalzstation, downstream.
Die beschriebene Erfindung und die beschriebenen vorteilhaften Weiterbildungen der Erfindung stellen auch in Kombination miteinander - soweit dies technisch sinnvoll ist - vorteilhafte Weiterbildungen der Erfindung dar.The invention described and the described advantageous developments of the invention are also in combination with each other - as far as is technically feasible - advantageous developments of the invention.
Hinsichtlich weiterer Vorteile und in konstruktiver und funktioneller Hinsicht vorteilhafter Ausgestaltungen der Erfindung wird auf die Unteransprüche sowie die Beschreibung von Ausführungsbeispielen unter Bezugnahme auf die beiliegenden Figuren verwiesen.With regard to further advantages and constructive and functional advantageous embodiments of the invention, reference is made to the dependent claims and the description of exemplary embodiments with reference to the accompanying figures.

The distance m between the two upstream auxiliary rolls 13 and 16 is greater than the distance n between the two press rolls 11 and 14. As a result, a tapered transport gap is formed by the 12 and 15, which causes air from a foldedconveyor belts sheet 1001 can be pressed out before it reaches the 11, 14 and there experiences its actual pressing.
