Description

Die Erfindung betrifft eine Transportvorrichtung zum Einziehen einer Bahn in eine bahnverarbeitende Maschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a transport device for drawing a web into a web-processing machine according to the preamble of claim 1.

Durch die DE 30 18 740 A1 ist eine Vorrichtung zum Einziehen von Materialbahnen bekannt, wobei eine Transportkette in einer Führung bewegbar und durch ein Kettenrad antreibbar ist. Um einen sicheren Vorschub der Transportkette auch bei ungünstiger relativer Lage zwischen Kettenanfang und Kettenrad zu gewährleisten, ist die Führungsschiene im Bereich des Kettenrades in einem Beispiel als Wippe um einen festen Drehpunkt und in einem zweiten Beispiel als durch U-förmige Ausstanzungen gebildete Zungen nachgiebig ausgebildet.By the DE 30 18 740 A1 a device for pulling material webs is known, wherein a transport chain is movable in a guide and driven by a sprocket. In order to ensure a safe feed of the transport chain even with unfavorable relative position between the chain start and sprocket, the guide rail in the region of the sprocket is resilient in one example as a rocker about a fixed pivot point and formed in a second example as tongues formed by U-shaped punched.

Weiterhin ist es bekannt, um beim Vorschub einer Transportkette in den Wirkungsbereich eines Antriebsrades einem Verklemmen von Kette und Antriebsrad derart vorzubeugen, dass der gesamte Antriebsmotor für das Antriebsrad relativ zu einer die Kette führenden Führung bewegbar angeordnet ist.Furthermore, it is known to prevent jamming of the chain and the drive wheel during the advance of a transport chain in the range of action of a drive wheel such that the entire drive motor for the drive wheel is arranged to be movable relative to a guide guiding the chain.

Die US 12 88 550 A zeigt einen gefederten Schutz für eine endlose Rollenkette.The US 12 88 550 A shows a spring-loaded protection for an endless roller chain.

Die DE 299 05 965 U1 beschreibt eine Führungsschiene zum Spannen einer endlosen Rollenkette.The DE 299 05 965 U1 describes a guide rail for tensioning an endless roller chain.

Der Erfindung liegt die Aufgabe zugrunde, eine Transportvorrichtung zum Einziehen einer Bahn in eine bahnverarbeitende Maschine zu schaffen.The invention has for its object to provide a transport device for drawing a web in a web-processing machine.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass eine Vermeidung eines Verklemmens von Antrieb und Kette, insbesondere einer Transportkette, erfolgt, ohne dass ein größerer baulicher Aufwand an der Lagerung der Motoren getätigt werden muss.The achievable with the present invention consist in particular in that an avoid jamming of the drive and chain, in particular a transport chain, takes place without a major construction effort on the storage of the motors must be made.

Gleichzeitig wird mit der Erfindung ein sicheres, störungsfreies Führen der Transportkette auf dem gesamten Bereich der Wechselwirkung mit dem Antriebsmittel erreicht, da jeder Punkt eines Teilstücks der Führung im genannten Bereich quer zur Transportrichtung reversibel auslenkbar ist. Dieses Teilstück ist vorteilhafter Weise als ganzes vom Antriebsmittel weg bewegbar ausgeführt.At the same time a safe, trouble-free guiding of the transport chain over the entire range of interaction with the drive means is achieved with the invention, since each point of a section of the guide in the said region is reversibly deflected transversely to the transport direction. This section is advantageously carried out as a whole movable away from the drive means.

Insbesondere vorteilhaft ist es auch, dass die einfache Bauweise eine Verwendung und Abänderungen gängiger Führungen erlaubt, und hierdurch bereits bestehende Transportvorrichtungen ohne größeren Aufwand jederzeit durch die Maßnahmen der vorliegenden Transportvorrichtung nachrüstbar sind.It is also particularly advantageous that the simple design allows use and modifications of common guides, and thereby already existing transport devices without much effort at any time by the measures of the present transport device can be retrofitted.

Auch kann auf aufwendige, bezüglich des Drehwinkels geregelte Antriebe verzichtet werden, da das dem Antriebsmittel benachbarte Teilstück der Führung einen ggf. auftretenden Versatz zwischen einander benachbarten Antriebsmittel und Transportkette ausgleicht.Also can be dispensed with consuming, with respect to the rotation angle controlled drives, since the drive means adjacent portion of the guide compensates for any offset between adjacent drive means and transport chain.

In einer vorteilhaften Ausführung ist lediglich das dem Antriebsmittel abgewandte Teilstück, einer C-förmigen Führung vom Rücken und dem dem Antriebsmittel zugewandten Teilstück der Führung abgetrennt und mittels zweier Federn, z. B. Druckfedern, reversibel vom Antriebsmittel weg bewegbar angeordnet.In an advantageous embodiment, only the part facing away from the drive means, a C-shaped guide from the back and the drive means facing portion of the guide is separated and by means of two springs, for. B. compression springs, reversibly arranged away from the drive means movable.

Eine ebenfalls vorteilhafte, weil Einbauraum sparende, Ausführung sieht die Ausführung der Federn als Zugfedern vor, welche das bewegbare Teilstück in seiner Normallage zum Antriebsmittel hin, als geschlossenes "C", halten.A likewise advantageous, because installation space-saving, execution provides for the execution of the springs as tension springs, which hold the movable portion in its normal position to the drive means, as a closed "C".

Von Vorteil ist ein einfacher, kostengünstiger und robuster Aufbau, z. B. mittels zweier das "C" im Bereich seines Rückens durchdringender Bolzen, wobei eine das "C" in Normallage haltende Federkraft über den Federweg mittels Muttern als Widerlager einstellbar ist.The advantage is a simple, inexpensive and robust construction, eg. Example by means of two the "C" in the region of his back penetrating bolt, wherein a "C" in normal position holding spring force over the spring travel by means of nuts as abutment is adjustable.

Eine Transportvorrichtung zum Transport einer Bahn 01, z. B. einer Materialbahn in bzw. durch eine Arbeitsmaschine zur Bearbeitung der Materialbahn, insbesondere zum Einziehen einer Bedruckstoffbahn 01 in eine Rollenrotationsdruckmaschine, weist ein Transportmittel 02, z. B. eine Transportkette 02 und mindestens ein die Transportkette 02 antreibendes Antriebsmittel 03; 04 auf.A transport device for transporting a web 01, z. B. a web in or through a working machine for processing the material web, in particular for drawing a printing substrate 01 in a web-fed rotary printing press, has Means of transport 02, z. B. a transport chain 02 and at least one transport chain 02 driving drive means 03; 04 on.

Beispielsweise ist die Bedruckstoffbahn 01 von einem Rollenträger 06 über ein Einzugwerk 07, durch ein oder mehrere Druckwerke 08, und, falls eine entsprechende Einrichtung vorgesehen ist, auch über einen Überbau 09 (Wende- und/oder Schnittbereich) und einen Trichterbereich 11 in die Rollenrotationsdruckmaschine einzuziehen (lediglich schematisch in Fig. 1 dargestellt). Der Verlauf der Bahn 01 ist in Transportrichtung T gesehen nach dem Transportmittel 02 strichliert dargestellt.For example, the printing material web 01 of a roller carrier 06 via a retraction unit 07, by one or more printing units 08, and, if a corresponding device is provided, also on a superstructure 09 (turning and / or cutting area) and a funnel area 11 in the web-fed rotary printing press to collect (only schematically in Fig. 1 shown). The course of the web 01 is seen in the transport direction T after the transport means 02 shown by dashed lines.

Zu diesem Zweck wird der Anfang der Bedruckstoffbahn 01, beispielsweise mittels einer nicht dargestellten Einziehspitze und einem Koppelstück, an der Transportkette 02 angeordnet. Die vorzugsweise endliche Transportkette 02 ist in einer Führung 12 (siehe Fig. 2 und 4) angeordnet, welche entlang des gewünschten und vorgewählten Weges der Bahn 01 verläuft. Die Führung 12 kann Weichen enthalten, welche verschiedene Transportwege ermöglicht. Die Führung 12 ist in vorteilhafter Ausführung als Schiene 12 mit C-förmigem Profil ausgebildet.For this purpose, the beginning of the printing substrate 01, for example by means of a Einziehspitze not shown and a coupling piece, arranged on the transport chain 02. The preferably finite transport chain 02 is in a guide 12 (see Fig. 2 and 4 ), which runs along the desired and preselected path of the web 01. The guide 12 may include switches, which allows different transport routes. The guide 12 is formed in an advantageous embodiment as a rail 12 with a C-shaped profile.

Der Antrieb der Transportkette 02 erfolgt beispielsweise von in Fig. 1 nicht dargestellten Elektromotoren auf Antriebsmittel 03; 04, welche entlang der Führung 12 in einer Länge I12 voneinander beabstandet sind, welche kleiner ist als eine Länge I02 der Transportkette 02, so dass die Transportkette 02 auf ihrem Weg durch die Rollenrotationsdruckmaschine jeweils zumindest mit einem Antriebsmittel 03; 04 zusammen wirkt und vor Verlassen des einen Antriebsmittels 03 bereits mit dem nachfolgenden Antriebsmittel 04 zusammen wirkt.The drive of the transport chain 02 takes place for example in Fig. 1 not shown electric motors on drive means 03; 04, which are spaced apart along the guide 12 in a length I12, which is smaller than a length I02 of the transport chain 02, so that the transport chain 02 on their way through the web-fed rotary printing press in each case at least with a drive means 03; 04 cooperates and before leaving the one drive means 03 already cooperates with the subsequent drive means 04.

Die Transportkette 02 (Fig. 2) weist in Transportrichtung T voneinander beabstandet Stege 13; 14 auf, welche als Anschlag mit einem Mitnehmer 16 des Antriebsmittels 03; 04, z. B. mit Zahnflanken von Zähnen 16 eines Kettenrades 03; 04, formschlüssig, oder zumindest als Mitnehmerverbindung, zusammen wirkt. Die Transportkette 02 kann als Gliederkette, als endliches Band mit entsprechenden Textur, oder in sonstiger Weise ausgeführt sein, welche auf ihrer mit dem Mitnehmer 16 zusammen wirkenden Seite in Transportrichtung T wirksame Anschläge aufweist. Eine Drehachse D des Kettenrades 03; 04 ist vorzugsweise maschinenfest bzgl. der Arbeitsmaschine angeordnet.The transport chain 02 ( Fig. 2 ) has in the transport direction T spaced apart webs 13; 14, which as a stop with a driver 16 of the drive means 03; 04, z. B. with tooth flanks of teeth 16 of a sprocket 03; 04, positive fit, or at least as driver connection, works together. The transport chain 02 may be designed as a link chain, as a finite band with appropriate texture, or in any other way, which has effective stops on its side cooperating with the driver 16 in the transport direction T. A rotation axis D of the sprocket 03; 04 is preferably machine-resistant with respect to the working machine.

Tritt nun das vorlaufende Ende der Transportkette 02 mit seiner ersten Rolle 13 in Reichweite der Zähne 16 des Kettenrades 04, so wirkt die Transportkette 02 im Bereich seines nachlaufenden Endes noch mit dem vorhergehenden Kettenrad 03 zusammen, welches die Transportkette 02 noch in Transportrichtung T schiebt.If now the leading end of the transport chain 02 with its first roller 13 within reach of the teeth 16 of the sprocket 04, then the transport chain 02 in the region of its trailing end still cooperates with the preceding sprocket 03, which pushes the transport chain 02 still in the transport direction T.

Bei ungünstiger Winkellage des sich um die Drehachse D drehenden Kettenrades 04 neigt der in Transportrichtung T gedrückte erste Steg 13, z. B. die erste Rolle 13 dazu, das Kettenrad 04 zu blockieren, da sie für den Fall einer starren Führung 12 weder ausweichen kann noch eine Entlastung entgegen der Transportrichtung T, d. h. entgegen des Schubes des vorhergehenden Kettenrades 03, erfolgen kann.In unfavorable angular position of the rotating about the rotation axis D sprocket 04 tends in the transport direction T depressed first ridge 13, z. B. the first roller 13 to block the sprocket 04, since they can neither dodge in the case of a rigid guide 12 nor a discharge against the transport direction T, d. H. against the thrust of the previous sprocket 03, can be done.

Zu diesem Zweck ist ein Teilstück 17 der Führung 12, z. B. ein Schenkel 17 der C-förmigen Führung 12, in einem dem Kettenrad 03; 04 benachbarten Bereich, d. h. zumindest auf einer Länge I12 der Führung 12, auf welcher die Zähne 16 des Kettenrades 03; 04 und die Rollen 13; 14 der Transportkette 02 zusammen wirken, quer zur Transportrichtung T und weg vom Kettenrad 03; 04 in eine Bewegungsrichtung B bewegbar ausgeführt.For this purpose, a portion 17 of the guide 12, z. B. a leg 17 of the C-shaped guide 12, in a sprocket 03; 04 adjacent area, d. H. at least over a length I12 of the guide 12, on which the teeth 16 of the sprocket 03; 04 and the rollers 13; 14 of the transport chain 02 act together, transverse to the transport direction T and away from the sprocket 03; 04 executed in a direction of movement B movable.

In einem ersten Ausführungsbeispiel nach Fig. 2 und 3 weist die C-förmige Führung 12 im Bereich des Kettenrades 03; 04 den vom Kettenrad 03; 04 entfernt liegenden Schenkel 17 einen dem Kettenrad 03; 04 nächstliegenden Schenkel 18, und einen zwischen den Schenkeln 17; 18 angeordneten Rücken 19 auf. Die Führung 12 ist beispielsweise mittels Schrauben 21 im Bereich des Rückens 19 an einer maschinenfesten Wand 22 befestigt.In a first embodiment according to Fig. 2 and 3 has the C-shaped guide 12 in the region of the sprocket 03; 04 from the sprocket 03; 04 remote leg 17 a the sprocket 03; 04 nearest legs 18, and one between the legs 17; 18 arranged back 19. The guide 12 is fastened, for example, by means of screws 21 in the region of the back 19 to a machine-fixed wall 22.

Das Kettenrad 03; 04 greift zwecks Förderung der Transportkette 02 durch eine Ausnehmung 23 im dem Kettenrad 03; 04 nächstliegenden Schenkel 18 in die Führung hinein. Der vom Kettenrad 03; 04 entfernt liegende Schenkel 17 ist zumindest auf einer Länge I17 relativ zum Kettenrad 03; 04 und quer zur Transportrichtung T auslenkbar angeordnet, welche größer oder gleich einer Länge ist, auf welcher ein Kopfkreis K des Kettenrades 03; 04 die fiktive Bewegungsbahn der Transportkette 02 ohne Auslenkung des Schenkels 17 schneidet.The sprocket 03; 04 engages in order to promote the transport chain 02 through a recess 23 in the sprocket 03; 04 nearest leg 18 into the guide. The sprocket 03; 04 remote leg 17 is at least over a length I17 relative to the sprocket 03; 04 and arranged transversely to the transport direction T deflectable, which is greater than or equal to a length on which a top circle K of the sprocket 03; 04 the fictitious trajectory of the transport chain 02 without deflection of the leg 17 cuts.

Hierzu ist der Schenkel 17 trennbar vom Rücken 19 angeordnet und nicht fest mit den übrigen Teilen der Führung 12 verbunden. Zwei voneinander in Transportrichtung T beabstandete Bolzen 24; 26 verlaufen entlang der Bewegungsrichtung B, d. h. nahezu senkrecht zur Transportrichtung T und nahezu senkrecht zur Drehachse D des Kettenrades 03; 04, im Bereich des Rückens 19 der C-förmigen Führung 12 und reichen zumindest auf der dem Kettenrad 03; 04 abgewandten Seite des Rückens 19 aus dem Rücken 19 heraus. Diese werden jeweils von einer im Schenkel 17 angeordneten Ausnehmung 27, z. B. einer Bohrung 27, aufgenommen, so dass der Schenkel 17 in Bewegungsrichtung B nahezu senkrecht zur Transportrichtung T und nahezu senkrecht zur Drehachse D des Kettenrades 03; 04 weitgehend linear geführt bewegbar ist. Ist die Bohrung 27 als Langloch mit einer Orientierung in Transportrichtung T ausgeführt, so ist neben einer linearen Bewegung senkrecht zur Transportrichtung T auch ein Verkippen bzw. eine Bewegung in einer zur Transportrichtung T senkrechten Richtung geneigten Richtung möglich. Die Bewegung des Schenkels 17 weist dann in der senkrecht zur Drehachse D liegenden Ebene.For this purpose, the leg 17 is arranged separable from the back 19 and not firmly connected to the other parts of the guide 12. Two spaced from each other in the transport direction T bolt 24; 26 extend along the direction of movement B, d. H. almost perpendicular to the transport direction T and almost perpendicular to the axis of rotation D of the sprocket 03; 04, in the region of the back 19 of the C-shaped guide 12 and extend at least on the sprocket 03; 04 opposite side of the back 19 out of the back 19 out. These are each arranged by a arranged in the leg 17 recess 27, z. B. a bore 27, so that the leg 17 in the direction of movement B almost perpendicular to the transport direction T and almost perpendicular to the axis of rotation D of the sprocket 03; 04 is largely linearly movable. If the bore 27 is designed as an oblong hole with an orientation in the transport direction T, in addition to a linear movement perpendicular to the transport direction T, tilting or movement in a direction inclined to the transport direction T is also possible. The movement of the leg 17 then points in the plane perpendicular to the axis of rotation D level.

Zwischen dem Schenkel 17 und einem Widerlager 28 am vom Kettenrad 04 abgewandten Ende des Bolzens 24; 26 ist eine Feder 29, insbesondere eine Druckfeder 29, angeordnet, welche den Schenkel 17 gegen den Rücken 19 drückt. Das Widerlager 28 ist vorteilhafter Weise entlang der Längsachse des Bolzens 24; 26 veränderbar angeordnet und ist im Beispiel als Scheibe 28 mit einer Mutter 32 ausgebildet, welche auf einem Außengewinde des Bolzens 24; 26 bewegbar angeordnet ist. Die Feder 29 drückt den Schenkel 17 in einer Normallage "N" gegen einen Anschlag 31, im Beispiel die dem Schenkel 17 zugewandte Seite des Rückens 19 (Fig. 2). Fig. 3 zeigt den Schenkel 17 in einer ausgelenkten Lage "A".Between the leg 17 and an abutment 28 on the end remote from the sprocket 04 of the bolt 24; 26 is a spring 29, in particular a compression spring 29, arranged, which presses the leg 17 against the back 19. The abutment 28 is advantageously along the longitudinal axis of the bolt 24; 26 arranged changeable and is formed in the example as a disc 28 with a nut 32 which on a External thread of the bolt 24; 26 is arranged movable. The spring 29 presses the leg 17 in a normal position "N" against a stop 31, in the example, the leg 17 facing side of the back 19 (FIGS. Fig. 2 ). Fig. 3 shows the leg 17 in a deflected position "A".

Insbesondere im Hook'schen Bereich der Feder 29 ist zum einen die zur Auslenkung erforderliche Federkraft einstellbar und zum anderen in gewissen Grenzen ein einfaches Nachstellen bei Ermüdung möglich. Ein unbeabsichtigtes Auslenken oder ein Auslenken bei zu hoher Kraft und daraus resultierende Probleme beim Antreiben der Transportkette 02 können durch einfache Justierung vermieden werden.In particular, in the Hooke area of the spring 29, on the one hand, the spring force required for the deflection is adjustable and, on the other hand, within certain limits, a simple readjustment under fatigue is possible. Unintentional deflection or deflection at too high a force and resulting problems in driving the transport chain 02 can be avoided by simple adjustment.

Ein exakter Anschluss einer Lauffläche 33 der Rollen 13; 14 wird dadurch erreicht, dass der Schenkel 17 in seiner Normallage N gegen die als Anschlag 31 wirkende Unterseite des Rückens 19 gedrückt ist.An exact connection of a tread 33 of the rollers 13; 14 is achieved in that the leg 17 is pressed in its normal position N against acting as a stop 31 underside of the back 19.

Im Beispiel ist an der Führung 12 im Bereich des Kettenrades 03; 04 jeweils am Schenkel 17; 18 ein Schutz 34; 36 angeordnet, wobei der vom Kettenrad 03; 04 entfernte Schutz 34 gemeinsam mit dem Schenkel 17 auslenkbar, und der dem Kettenrad 03; 04 nächstliegende Schutz 36 maschinenfest und ebenfalls eine Ausnehmung für das Kettenrad 03; 04 aufweisend ausgeführt ist.In the example, on the guide 12 in the region of the sprocket 03; 04 each on the leg 17; 18, a guard 34; 36 arranged, wherein the sprocket 03; 04 remote protection 34 together with the leg 17 deflectable, and the sprocket 03; 04 nearest protection 36 machine-fixed and also a recess for the sprocket 03; 04 is executed.

In einem zweiten Ausführungsbeispiel (Fig. 4 und 5) durchgreift der Bolzen 24; 26 den Schenkel 17 und den mit dem Schenkel 18 verbundenen Rücken 19, wobei das dem Kettenrad 03; 04 zugewandte Ende des Bolzens 24; 26 aus dem maschinenfesten Schenkel 18 herausragt und das gegenüberliegende Ende mit dem auslenkbaren Schenkel 17 verbunden ist. Letzteres kann wie im Beispiel durch einen am Bolzen 24; 26 angeordneten, mit dem Schenkel 17 zusammen wirkenden Anschlag 37 erfolgen. Der Bolzen 24; 26 ist mit seiner Längsachse wieder nahezu senkrecht zur Transportrichtung T und senkrecht zur Drehachse D des Kettenrades 03; 04 orientiert und ist entlang dieser Drehachse D in der Führung 12 bewegbar. Das auf der dem Kettenrad 03; 04 zugewandten Seite der Führung 12 herausragende Ende des Bolzens 24; 26 ist mit einer Feder 38, z. B. einer Zugfeder 38, verbunden, welche mit ihrem zweiten Ende derart gestellfest festgelegt ist, dass die Wirkrichtung der Zugfeder 38 eine Komponente in axialer Richtung des Bolzens 24; 26 und entgegengesetzt zur Bewegungsrichtung B aufweist.In a second embodiment ( 4 and 5 ) passes through the bolt 24; 26 the leg 17 and connected to the leg 18 back 19, wherein the sprocket 03; 04 facing the end of the bolt 24; 26 protrudes from the machine-fixed leg 18 and the opposite end is connected to the deflectable leg 17. The latter can, as in the example by a bolt 24; 26 arranged, together with the legs 17 acting stop 37 take place. The bolt 24; 26 is again with its longitudinal axis almost perpendicular to the transport direction T and perpendicular to the axis of rotation D of the sprocket 03; 04 oriented and is along this Rotary axis D in the guide 12 movable. That on the sprocket 03; 04 facing side of the guide 12 outstanding end of the bolt 24; 26 is connected to a spring 38, z. B. a tension spring 38, which is fixed to the frame with its second end so that the effective direction of the tension spring 38 is a component in the axial direction of the bolt 24; 26 and opposite to the direction of movement B.

Im Ausführungsbeispiel ist das gestellfeste Ende der Zugfeder 38 an einer an der Wand 22 angeordneten Halterung 39 mittels eines die Halterung 39 durchgreifenden Bolzens 41 angeordnet. Hierzu weist der Bolzen 41 an dem der Zugfeder 38 zugewandten Ende z. B. eine Öse 42 zur Aufnahme eines abgebogenen Endes der Zugfeder 38, und zumindest im Bereich der Halterung 39 und an seinem der Zugfeder 38 abgewandten Ende ein Außengewinde auf, welches mit einer Mutter 43 als Widerlager 43 für die Zugfeder 38 bzw. als Anschlag 43 zwecks Justierung zusammen wirkt.In the embodiment, the frame-fixed end of the tension spring 38 is arranged on a arranged on the wall 22 holder 39 by means of a bracket 39 by cross-bolt 41. For this purpose, the bolt 41 at the tension spring 38 facing the end z. B. an eyelet 42 for receiving a bent end of the tension spring 38, and at least in the region of the bracket 39 and at its end remote from the tension spring 38 on an external thread, which with a nut 43 as an abutment 43 for the tension spring 38 or as a stop 43rd for the purpose of adjustment works together.

Die Anordnung der Zugfeder 38 ist derart ausgeführt, dass die Vorspannung der Zugfeder 38 den auslenkbaren Schenkel 17 zum geschlossenen "C" an den Rücken 19 bzw. den Anschlag 31 der Führung 12 heranzieht.The arrangement of the tension spring 38 is designed such that the bias of the tension spring 38, the deflectable leg 17 to the closed "C" on the back 19 and the stop 31 of the guide 12 draws.

Besonders vorteilhaft hinsichtlich des Bauraums ist die Ausführung der Transportvorrichtung gemäß dem zweiten Ausführungsbeispiel, wenn, wie in Fig. 5 strichliert angedeutet, eine zweite Führung parallel zur Führung 12 verlaufen soll. Zugfeder 38 und wesentliche Teile des Bolzens 24; 26 sind auf der dem Kettenrad 03; 04 zugewandten Seite der Führung 12 bzw. des auslenkbaren Schenkels 17 angeordnet.Particularly advantageous in terms of space is the execution of the transport device according to the second embodiment, if, as in Fig. 5 indicated by dashed lines, a second guide should extend parallel to the guide 12. Tension spring 38 and essential parts of the bolt 24; 26 are on the sprocket 03; 04 facing side of the guide 12 and the deflectable leg 17 is arranged.

Vorteilhaft ist die Ausführung der Halterung 38 derart, dass in seinem weiteren Verlauf ein das Kettenrad 03; 04 antreibender Motor 44 sowohl von der Seite der Wand 22 als auch von der der Wand 22 abgewandten Seite des Kettenrades 04 (44', strichliert) anordenbar ist.Advantageously, the embodiment of the holder 38 is such that in its further course a the sprocket 03; 04 driving motor 44 from both the side of the wall 22 and the side facing away from the wall 22 of the sprocket 04 (44 ', dashed lines) can be arranged.

Durch die bewegbare Lagerung des Teilstücks 17 der Führung 12 im gesamten wechselwirkenden Bereich ist ein Verklemmen auch für den Fall sicher ausgeschlossen, dass eine nicht exakt in das Kettenrad eingreifende Transportkette auch im weiteren Verlauf im Bereich des Kettenrades 03; 04 weg vom Kettenrad 03; 04 ausweichen kann.Due to the movable mounting of the portion 17 of the guide 12 in the entire interacting area jamming is excluded for the case safely that a not exactly engaging in the sprocket transport chain in the further course in the range of the sprocket 03; 04 away from the sprocket 03; 04 can dodge.

Die Transportvorrichtung funktioniert wie folgt:The transport device works as follows:

Die Transportkette 02 befindet sich zwecks Transportes der an ihr befestigten Bahn 01 auf ihrem Weg durch die Arbeitsmaschine. Hierbei tritt auf einem Wegabschnitt die Transportkette 02 mit ihrem ersten Steg 13 in Reichweite der Mitnehmer 16 des Antriebsmittels 04, z. B. in den Kopfkreis des Kettenrades 04, während die Transportkette 02 im Bereich seines nachlaufenden Endes noch mit einem vorhergehenden Antriebsmittel 03 zusammen wirkt, welches die Transportkette 02 in Transportrichtung T schiebt.The transport chain 02 is located in order to transport the attached to her orbit 01 on her way through the machine. Here occurs on a path section, the transport chain 02 with its first web 13 within reach of the driver 16 of the drive means 04, z. B. in the top circle of the sprocket 04, while the transport chain 02 in the region of its trailing end still cooperates with a preceding drive means 03, which pushes the transport chain 02 in the transport direction T.

Bei ungünstiger relativer Lage zwischen Mitnehmer 16 und erstem Steg 13 bzw. dessen Anschlages 13, trifft der Mitnehmer 16 derart auf den Steg 13, dass sie sich gegenseitig zu blockieren drohen. Beispielsweise greift ein Zahn 16 des Kettenrades 04 nicht in den Zwischenraum zwischen den Rollen 13; 14, sondern drückt auf die Rolle 13.In unfavorable relative position between the driver 16 and the first web 13 and its stop 13, the driver 16 hits the web 13 in such a way that they threaten to block each other. For example, a tooth 16 of the sprocket 04 does not engage in the space between the rollers 13; 14, but presses on the role 13.

Die nahezu senkrecht zur Transportrichtung T und senkrecht zur Drehachse D des Antriebsmittels 04 gerichtete Komponente der durch den Zahn 16 auf die Rolle 13 ausgeübten Kraft bewirkt nun ihrerseits eine Bewegung der Rolle 13 und des auslekbaren Schenkels 17 in Bewegungsrichtung B, so dass ein weiteres Drehen des Antriebsmittels 04 und ein sicherer Weitertransport der Transportkette 02 ohne ein Blockieren ermöglicht wird.The almost perpendicular to the transport direction T and perpendicular to the rotational axis D of the drive means 04 directed component of the force exerted by the tooth 16 on the roller 13 force now causes in turn a movement of the roller 13 and the deflectable leg 17 in the direction of movement B, so that a further rotation of the Drive means 04 and a safe onward transport of the transport chain 02 is made possible without blocking.
