Description

Die Erfindung betrifft eine Fördereinrichtung für Bogenmaterial in einer Verarbeitungsmaschine nach dem Oberbegriff des unabhängigen Anspruches 1. Die Erfindung eignet sich insbesondere für eine Bogenmaterial verarbeitende Druck- bzw. Lackiermaschine.The invention relates to a conveyor for sheet material in a processing machine according to the preamble of independent claim 1. The invention is particularly suitable for a sheet material processing printing or varnishing machine.

Eine Fördereinrichtung dieser Art ist aus DE 2 246 061 B als Zugmittelgetriebe, speziell als Kettenfördereinrichtung, zum Bogentransport mit Greiferwagen (Bogenhaltemittel) bekannt, welche den Raum zwischen zwei benachbarten, gestellfesten Führungsschienen staub- und schmiermitteldicht abkapselt. Hierzu sind Abdeckelemente vorgesehen, welche in Anlage zu den Gleit-/Führungsschienen insbesondere an der Innenseite, d.h. in Richtung der Greiferwagen, gehalten sind. Damit wird eine vollkommene Abdichtung der Transportketten sowie der Führungsschienen erzielt. Bei Bedarf kann jedes Abdeckelement mittels Federdruck in Anlage gegen die Führungsschiene gehalten sein.A conveyor of this kind is made DE 2 246 061 B as a traction mechanism, especially as a chain conveyor, for sheet transport with gripper carriage (sheet holding means) known which dust-tight and lubricant tightly seals the space between two adjacent, frame-mounted guide rails. For this purpose, cover elements are provided, which are held in contact with the slide / guide rails, in particular on the inside, ie in the direction of the gripper carriage. Thus, a perfect seal of the transport chains and the guide rails is achieved. If necessary, each cover can be held by means of spring pressure in abutment against the guide rail.

Gemäß DE 39 39 250 C1 ist eine Fördereinrichtung für einen einem Druckzylinder nachgeordneten Bogenausleger bekannt. Die Fördereinrichtung umfasst einen um Kettenräder endlos umlaufenden Kettentrieb (Zugmittelgetriebe), der ein unteres und ein oberes Trum aufweist und in gestellfesten Kettenschienen geführt ist. In Abständen sind am Kettentrieb für den Bogentransport an einer Bogenkante mehrere Bogenhaltemittel, hier als Greifersysteme ausgebildet, angeordnet. Der Fördereinrichtung, speziell dem unteren Trum, ist unterhalb in einem definierten Abstand eine Bogenleiteinrichtung zugeordnet, welche sich im Wesentlichen von dem in Förderrichtung ersten Kettenradpaar bis zu einer Bogenbremseinrichtung erstreckt.According to DE 39 39 250 C1 is a conveyor for a printing cylinder downstream sheet boom known. The conveyor comprises a chain drive endlessly revolving around chain wheels (traction mechanism transmission), which has a lower and an upper run and is guided in frame-fixed chain rails. At intervals, a plurality of sheet holding means, here designed as gripper systems, are arranged on the chain drive for the sheet transport at an arc edge. The conveyor, especially the lower run, is assigned below a defined distance a sheet guide, which extends substantially from the first sprocket pair in the conveying direction to a sheet braking device.

Aus EP 1 422 062 A2 ist eine Trocknervorrichtung für eine Beschichtungsmaschine bekannt, die eine zwischen zwei Druckzylindern angeordnete Fördereinrichtung aufweist. Die Fördereinrichtung umfasst ein endlos um Umlenkelemente umlaufendes Fördermittel mit einem oberen und einem unteren Trum sowie in Abständen angeordnete Bogenhaltemittel. Dem unteren Trum ist unterhalb in einem definierten Abstand eine Bogenleiteinrichtung zugeordnet, welche sich im Wesentlichen zwischen den beiden Umlenkelementen erstreckt.Out EP 1 422 062 A2 For example, a drying device for a coating machine is known, which has a conveying device arranged between two printing cylinders. The conveyor comprises an endlessly circulating around deflecting conveyor with an upper and a lower run and arranged at intervals sheet holding means. The lower strand is assigned below a sheet guide at a defined distance, which extends substantially between the two deflection elements.

Derartige Fördereinrichtungen weisen für die Versorgung des Zugmittelgetriebes, insbesondere als Kettentrieb, bevorzugt eine Zentralschmierung auf oder sind manuell mit Schmierstoff zu versorgen. Bei seitlich offenen als auch gekapselten Kettentrieben kann Schmierstoff am Rand der Führungsschienen austreten.Such conveyors have for the supply of the traction mechanism, in particular as a chain drive, preferably a central lubrication or are manually supplied with lubricant. For laterally open or encapsulated chain drives, lubricant can escape at the edge of the guide rails.

Der Erfindung liegt die Aufgabe zu Grunde, eine Fördereinrichtung der eingangs genannten Art zu schaffen, die die tribotechnischen Zustände am Zugmittelgetriebe, vorzugsweise an einem Kettentrieb, verbessert und dem Austreten von Schmierstoff entgegen wirkt.The invention is based on the object to provide a conveyor of the aforementioned type, which improves the tribotechnical conditions on the traction mechanism, preferably on a chain drive, and counteracts the escape of lubricant.

Die Aufgabe wird durch die Ausbildungsmerkmale von Anspruch 1 gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.The object is solved by the training features of claim 1. Further developments emerge from the subclaims.

Ein erster Vorteil ist darin begründet, dass die erfindungsgemäße Fördereinrichtung universell an offenen oder gekapselten Zugmittelgetrieben, insbesondere Kettentrieben, einsetzbar ist. Derartige Zugmittelgetriebe umfassen wenigstens ein endlos umlaufendes, schmiegsames Zugmittel, beispielsweise eine Kette, sowie zwei Umlenkelemente, beispielsweise Kettenräder, die von dem Zugmittel teilweise umschlungen sind. Fördereinrichtungen mit Zugmittelgetriebe dieser Art sind bekanntlich mit Bogenhaltemitteln für den Bogentransport gekoppelt und in gestellfesten Führungsmitteln geführt. Zumindest an der den Bogenhaltemitteln zugewandten Innenseite des Zugmittelgetriebes, insbesondere am Kettentrieb, ist wenigstens ein Mittel, insbesondere in Form eines Abdeckelements, vorgesehen, welches den aus den Zwischenräumen des Zugmittelgetriebes, insbesondere Kettentriebes, bzw. der Führungsschienen möglicherweise austretenden Schmierstoff dem Zugmittelgetriebe erneut zuführt. Insbesondere bei Kettentrieben auf Basis von Rollenkettengetrieben werden somit die tribotechnischen Zustände im Wirkbereich von Bolzen und Buchse sowie von Buchse und Rolle, speziell in den Kettengelenken, spürbar verbessert. Somit können die Nutzungsdauer des Kettentriebes spürbar verbessert, der Schmierstoffverbrauch gesenkt und ein mögliches Abtropfen von Schmierstoff innerhalb der Verarbeitungsmaschine vermieden werden.A first advantage is due to the fact that the conveyor according to the invention can be used universally on open or encapsulated traction mechanism gears, in particular chain drives. Such traction mechanism comprise at least one endless, flexible traction means, such as a chain, and two deflecting elements, such as sprockets, which are partially wrapped by the traction means. Conveyors with traction mechanism of this type are known to be coupled with sheet holding means for sheet transport and guided in frame-mounted guide means. At least at the sheet holding means facing inside of the traction mechanism, in particular on the chain drive, is at least a means, in particular in the form of a cover, is provided, which again supplies the lubricant from the intermediate spaces of the traction mechanism, in particular chain drive, or the guide rails escaping lubricant to the traction mechanism. In particular, in chain drives based on roller chain drives tribotechnical conditions in the effective range of bolts and bushing and bushing and roller, especially in the chain joints, thus noticeably improved. Thus, the useful life of the chain drive can be significantly improved, the lubricant consumption can be reduced and a possible dripping of lubricant within the processing machine can be avoided.

Als zweiter Vorteil kann aufgeführt werden, dass in einer weiteren Ausbildung der Fördereinrichtung wenigstens ein Mittel, insbesondere in Form wenigstens eines Leitflächenelements, vorgesehen ist, welches das Zurückfließen von ausgetretenem Schmierstoff in Richtung des Schmierstoffraums im Zugmittelgetriebe, insbesondere in einem Kettentrieb, unterstützt.As a second advantage, it can be stated that, in a further embodiment of the conveyor, at least one means, in particular in the form of at least one guide surface element, is provided, which supports the backflow of leaked lubricant in the direction of the lubricant space in the traction mechanism, in particular in a chain drive.

Ein dritter Vorteil ergibt sich daraus, dass der am Zugmittelgetriebe im Bereich des unteren Trums bzw. der Führungsschiene als auch der möglicherweise im Bereich des oberen Trum bzw. der Führungsschiene austretende Schmierstoff mittels wenigstens einem mit dem Zugmittelgetriebe umlaufenden Abdeckelement in den Schmierstoffraum zurück gefördert wird. Weiterhin kann der am Zugmittelgetriebe im Bereich des unteren Trums ausgetretene Schmierstoff im oberen Trum, bedingt durch die Umlenkung des Zugmittelgetriebes, mittels Schwerkraft in den Schmierstoffraum des Zugmittelgetriebes zurückfließen. Dieses Arbeitsprinzip kann zusätzlich durch die Anordnung wenigstens eines Leitflächenelements unterstützt werden. In Weiterbildung kann das Zugmittelgetriebe auch teilweise oder vollständig mit mehreren Abdeckelementen gekapselt ausgebildet sein.A third advantage results from the fact that the lubricant exiting at the traction mechanism in the region of the lower run or the guide rail as well as the lubricant possibly exiting in the region of the upper run or the guide rail is conveyed back into the lubricant space by means of at least one cover element revolving around the traction mechanism. Furthermore, the leaked at the traction mechanism in the region of the lower strand lubricant in the upper strand, due to the deflection of the traction mechanism, flow back by gravity into the lubricant space of the traction mechanism. This working principle can be additionally supported by the arrangement of at least one guide surface element. In a further development, the traction mechanism can also be partially or completely encapsulated with a plurality of cover elements.

Als vierter Vorteil kann genannt werden, dass insbesondere bei offenen Zugmittelgetrieben, speziell Kettentrieben, eine mögliche Verbindung von Schmierstoff und vagabundierenden Puderpartikeln spürbar reduziert werden kann, indem der möglicherweise austretende Schmierstoff umgehend in den Schmierstoffraum zwischen den Führungsschienen zurückgefördert wird. In der Weiterbildung mit mehreren Abdeckelementen kann durch teilweise oder vollständige Kapselung des Zugmittelgetriebes ein möglicher Kontakt mit vagabundierenden Puderpartikeln reduziert oder ausgeschlossen werden.As a fourth advantage can be mentioned that, especially in open traction transmissions, especially chain drives, a possible connection of lubricant and vagrant powder particles can be significantly reduced by the possibly leaking lubricant immediately in the lubricant space between the guide rails is conveyed back. In the development with multiple cover elements, a possible contact with stray powder particles can be reduced or eliminated by partial or complete encapsulation of the traction mechanism.

Die vorliegende Fördereinrichtung für Bogenmaterial ist grundsätzlich überall dort für den Bogentransport in einer Verarbeitungsmaschine einsetzbar, wo das Bogenmaterial nicht an Bogenführungszylindern transportiert wird.The present conveyor for sheet material is basically everywhere there for the sheet transport in a processing machine used where the sheet material is not transported on bow guide cylinders.

Einer Bogenrotationsdruckmaschine mit Druck-/Lackwerken ist beispielsweise in Förderrichtung 5 des Bogenmaterials ein Ausleger 1 nachgeordnet. Der Ausleger 1 besteht unter anderem aus einer in Förderrichtung 5 endlos über Umlenkelemente umlaufenden Fördereinrichtung 2 mit einem oberen und unteren Trum 10, 11 und mehreren in Abständen angeordneten Bogenhaltemitteln 3 zum Erfassen einer Bogenkante. Getriebetechnisch stellt die Fördereinrichtung 2 ein Zugmittelgetriebe dar.A sheet-fed rotary printing machine with printing / coating units, for example, downstream of a boom 1 in the conveying direction 5 of the sheet material. The boom 1 consists, inter alia, of a conveyer 2 endlessly circulating in the conveying direction 5 with an upper and lower strand 10, 11 and a plurality of spaced sheet holding means 3 for detecting a sheet edge. Transmission technology, the conveyor 2 is a traction mechanism.

Weiterhin umfasst die Fördereinrichtung 2 eine obere und eine untere Führungsschiene 15, 16, welche mittels einer Halterung 14 an einem Seitengestell 13 angeordnet sind und in denen das Zugmittel geführt ist.
Beispielsweise umfassen die Bogenhaltemittel 3 Greifersysteme, welche das jeweils im Greiferschluss fixierte Bogenmaterial an einer Bogenkante transportieren. Dabei wird das Bogenmaterial mit einer Seite, vorzugsweise der Unterseite, entlang einer mit Blasluft und/oder Saugluft betreibbaren Bogenleiteinrichtung 7 über eine Bogenbremseinrichtung 6 in Förderrichtung 5 in Richtung eines Auslegerstapels 4 zwecks Ablage auf dem Auslegerstapel 4 transportiert.Furthermore, the conveyor 2 comprises an upper and a lower guide rail 15, 16, which are arranged by means of a holder 14 on a side frame 13 and in which the traction means is guided.
For example, the sheet holding means 3 comprise gripper systems which transport the respective sheet material fixed in the gripper closure at an edge of the sheet. In this case, the sheet material is transported with one side, preferably the underside, along a sheet blowing device 7 operable with blown air and / or suction via a sheet braking device 6 in the conveying direction 5 in the direction of a delivery stack 4 for storage on the delivery pile 4.

Die Fördereinrichtung 2 ist beispielsweise als Kettentrieb 12 mit Umlenkelementen in Form von ersten und zweiten Kettenrädern 8, 9 ausgebildet. Die Bogenleiteinrichtung 7 ist bevorzugt mit einem Pneumatiksystem gekoppelt, so dass vorzugsweise eine auf einem Luftpolster schwebende Bogenführung realisierbar ist. Bogenleiteinrichtungen 7 dieser Art sind bekanntlich zumindest unterhalb einer idealen Führungsebene des Bogenmaterials angeordnet.The conveyor 2 is formed, for example, as a chain drive 12 with deflecting elements in the form of first and second sprockets 8, 9. The sheet guide 7 is preferably coupled to a pneumatic system, so that preferably a floating on an air cushion sheet guide can be realized. Sheet guiding devices 7 of this type are known to be arranged at least below an ideal guide plane of the sheet material.

Zumindest an der den Bogenhaltemitteln 3 zugekehrten Innenseite der Fördereinrichtung 2 ist wenigstens ein erstes Abdeckelement 17 angeordnet. Das Abdeckelement 17 weist mindestens eine der Führungsschiene 15 oder 16 benachbart zugeordnete Schmierstofftasche 19 auf. Bevorzugt weist ein derartiges Abdeckelement 17 jeder Führungsschiene 15, 16 zugeordnet wenigstens eine derartige Schmierstofftasche 19 auf.

If the covering element 17 is arranged on the inside of the conveying device 2 in the area of the sheet-holding means 3, then the covering element 17 can have an opening for the bolt or pins 28 coupled to the sheet-holding means 3. Alternatively, the cover 18 may have an opening for bolts 28 on the outside of the conveyor 2.

Bevorzugt weist jedes Abdeckelement 17, 18 mindestens eine jeweils der oberen und der unteren Führungsschiene 15, 16 benachbart zugeordnete Schmierstofftasche 19 auf. Jedes Abdeckelement 17, 18 umfasst ein Unterteil 26 und ein Oberteil 27 auf, welche jeweils der unteren Führungsschiene 16 und der oberen Führungsschiene 15 zugeordnet sind. Hierzu weist jedes Abdeckelement 17, 18 eine der unteren Führungsschiene 16 und der oberen Führungsschiene 15 zugeordnete Anlagefläche 25 auf. Jedes Abdeckelement 17, 18 kann mittels einer Kraft, bevorzugt einer Druckfeder, mit seinen Anlageflächen 25 gegen die zugeordnete Seitenfläche der Führungsschiene 15, 16 in Anlagekontakt sein.Preferably, each cover element 17, 18 at least one of the upper and the lower guide rail 15, 16 adjacent associated lubricant pocket 19. Each cover element 17, 18 comprises a lower part 26 and an upper part 27, which are respectively associated with the lower guide rail 16 and the upper guide rail 15. For this purpose, each cover element 17, 18 has a contact surface 25 assigned to the lower guide rail 16 and the upper guide rail 15. Each cover element 17, 18 may be in abutting contact with its contact surfaces 25 against the associated side surface of the guide rail 15, 16 by means of a force, preferably a compression spring.

In einer Weiterbildung weist das Abdeckelement 17, 18 in Förderrichtung 5 der Fördereinrichtung 2 betrachtet eine Anlaufschräge 24 auf, welche jeweils in die der Führungsschiene 15, 16 zugekehrte Anlagefläche 25 übergeht. Dabei kann die Anlaufschräge 24' auch in die in Förderrichtung 5 erste Schmierstofftasche 19 übergehen.In a further development, the cover 17, 18 in the conveying direction 5 of the conveyor 2 viewed on a run-on slope 24, which in each case in the guide rail 15, 16 facing contact surface 25 passes. In this case, the run-on slope 24 'can also pass into the first lubricant pocket 19 in the conveying direction 5.

Vorzugsweise sind in Förderrichtung 5 der Fördereinrichtung 2 in Abständen zueinander mehrere Schmierstofftaschen 19 an dem jeweiligen Abdeckelement 17, 18 hintereinander angeordnet. Dabei sind die Schmierstofftaschen 19 in Förderrichtung 5 zur Anlagefläche 25 vorzugsweise in einem spitzen Winkel α geneigt angeordnet. Die Schmierstofftaschen 19 können verschiedene geometrische Ausbildungen aufweisen. Beispielsweise können die Schmierstofftaschen 19 sägezahnartig ausgeformt sein. Weiterhin können die Schmierstofftaschen 19 in sich selbst eine Neigung in Richtung der benachbarten Führungsschienen 15, 16 aufweisen.Preferably, in the conveying direction 5 of the conveyor 2 at intervals to each other a plurality of lubricant pockets 19 on the respective cover 17, 18 are arranged one behind the other. In this case, the lubricant pockets 19 are arranged inclined in the conveying direction 5 to the contact surface 25 preferably at an acute angle α. The lubricant pockets 19 may have various geometric configurations. For example, the lubricant pockets 19 may be formed like a sawtooth. Furthermore, the lubricant pockets 19 may in themselves have an inclination in the direction of the adjacent guide rails 15, 16.

Die Wirkungsweise der Vorrichtung ist wie folgt: Der Kettentrieb 12 wird vom Hauptantrieb der Verarbeitungsmaschine oder mittels Einzelantrieb in Förderrichtung 5 angetrieben. Das jeweilige Abdeckelement 17, 18 wird mit dem Kettentrieb 12 entlang der gestellfesten Führungsschienen 15, 16 bewegt. Dabei wird aus dem Kettentrieb 12 seitlich austretender Schmierstoff von den Führungsschienen 15, 16 abgestreift und von den den Führungsschienen 15, 16 zugeordneten Schmierstofftaschen 19 aufgenommen.The mode of operation of the device is as follows: The chain drive 12 is driven by the main drive of the processing machine or by means of a single drive in the conveying direction 5. The respective cover element 17, 18 is moved with the chain drive 12 along the frame-fixed guide rails 15, 16. In this case, lubricant exiting laterally from the guide rails 15, 16 is picked up from the chain drive 12 and taken up by the lubricant pockets 19 assigned to the guide rails 15, 16.

Insbesondere im Bereich der unteren Führungsschiene 16 wird der in Richtung der Seitenflächen der Führungsschiene 16 herausgedrückte und durch die Schwerkraft langsam abtropfende Schmierstoff mittels der Abdeckelemente 17, 18 von diesen Seitenflächen abgestreift und in den Schmierstofftaschen 19 aufgenommen. Im Bereich der oberen Führungsschiene 15 fließt der (inzwischen durch die Umkehr der Bewegungsrichtung des Kettentriebes 12 auf dem Kopf stehende) Schmierstoff in Folge der Schwerkraft langsam aus den Schmierstofftaschen 19 in Richtung des Schmierstoffraumes 23 und wird wiederum den Elementen des Kettentriebes 12 zugeführt. Hierbei wird die Fließströmung des Schmierstoffes durch die Leitflächenelemente 20, speziell deren Leitflächen 21, unterstützt. Der Schmierstoff wird über die Leitflächen 21 dem Schmierstoffraum 23 erneut zugeführt. Zusätzlich kann möglicherweise an der oberen Führungsschiene 15 seitlich austretender Schmierstoff von den zugeordneten Schmierstofftaschen 19 aufgenommen werden.In particular, in the area of the lower guide rail 16, the lubricant pushed out in the direction of the side surfaces of the guide rail 16 and slowly dripping off by gravity is stripped off these side surfaces by means of the cover elements 17, 18 and received in the lubricant pockets 19. In the area of the upper guide rail 15, the lubricant (now standing upside down by the reversal of the direction of movement of the chain drive 12) flows slowly out of the lubricant pockets 19 in the direction of the lubricant space 23 as a result of gravity and is in turn supplied to the elements of the chain drive 12. In this case, the flow of the lubricant through the guide surface elements 20, especially their guide surfaces 21, supported. The lubricant is supplied via the guide surfaces 21 to the lubricant space 23 again. Additionally, laterally escaping lubricant may possibly be received by the associated lubricant pockets 19 on the upper guide rail 15.
