Description

Die Erfindung betrifft eine Vorrichtung für den automatischen Stapelwechsel nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for the automatic stack change after the preamble of claim 1.

In bogenverarbeitenden Maschinen ist es erwünscht, zur Steigerung des Durchsatzes Bogenstapel unterbrechungsfrei zuzuführen, so daß der Produktionsablauf beim Stapelwechsel nicht gestört wird. Dazu kann in einem Bogenanleger einer bogenverarbeitenden Maschine eine Non-Stop-Einrichtung vorgesehen sein. Die Non-Stop-Einrichtung dient dazu, einen bereits weitgehend abgearbeiteten Bogenstapel vor der Zufuhr eines neuen Bogenstapels zu unterfangen und für die weitere Verarbeitung zu halten und anzuheben. Der dabei anfallende Stapelrest wird mittels der Non-Stop-Einrichtung kontinuierlich zur Vereinzelung der Bogen angehoben. Während dessen wird ein neuer Bogenstapel unterhalb des Stapelrestes in den Bogenanleger eingefahren und über einen bestimmten Ablauf mit dem Stapelrest vereinigt. Hierbei werden in der Non-Stop-Einrichtung beispielsweise rechenartige Vorrichtungen eingesetzt, um den Stapelrest zu tragen. Bei dem Stapelwechselvorgang wird der Rechen zunächst in den Bereich unter den Stapelrest eingefahren und später bei Zufuhr des neuen Bogenstapels zwischen Stapelrest und neuem Bogenstapel wieder herausgezogen. Die Positionierung des Rechens ist hierbei zu überwachen, damit der Stapelrest jeweils vollständig unterfangen ist und der neue Bogenstapel nach der Vereinigung einwandfrei weiter transportiert werden kann. In sheet-processing machines, it is desirable to increase the Feed throughput sheet stack uninterrupted, so that the Production process is not disturbed when changing stacks. This can be done in one Sheet feeder of a sheet processing machine a non-stop device be provided. The non-stop facility is used to a large extent processed sheet stack before feeding a new sheet stack undertake and keep and raise for further processing. The one there accruing stack remainder is continuously by means of the non-stop device Separation of the sheets raised. In the meantime, a new stack of sheets retracted into the sheet feeder below the remainder of the stack and over one certain process combined with the rest of the stack. Here, in the non-stop facility for example, rake-like devices used to To carry pile rest. In the batch change process, the rake is first in the area under the remainder of the stack and later when the new one is fed Sheet stack between the rest of the stack and the new sheet stack again pulled out. The positioning of the rake is to be monitored here the rest of the stack is completely underpinned and the new stack of sheets after the association can be transported flawlessly.

Es ist bekannt, an Non-Stop-Einrichtungen Sensoren einzusetzen, mittels derer ein Stapelrechen in seiner Position in Beziehung auf den Bogenstapel erfaßt werden kann. Beispielsweise zeigt die DE-PS 1 095 297 einen Bogenanleger mit mehreren Stapelhubwerken. Der Bogenanleger ist mit einer Non-Stop-Vorrichtung in Form eines Stapelrechens versehen. Die Bewegung des Stapelrechens in den Bogenanleger hinein und aus dem Bogenanleger heraus wird über elektrische Schalter gesteuert. Solche Vorrichtungen sind nicht anwendbar für Non-Stop-Einrichtungen mit Einzelstab-Betrieb.It is known to use sensors on non-stop devices by means of which a Stacking rakes can be detected in their position in relation to the sheet stack can. For example, DE-PS 1 095 297 shows a sheet feeder with several Stapelhubwerken. The sheet feeder is in shape with a non-stop device a stacking rake. The movement of the stack rake in the Sheet feeder in and out of the sheet feeder is via electrical Switch controlled. Such devices are not applicable to non-stop facilities with single rod operation.

Aufgabe der Erfindung ist es, eine Vorrichtung nach dem Oberbegriff des Patentanspruchs 1 so zu gestalten, daß die Positionierung jedes einzelnen Rechenstabes erfaßbar ist.The object of the invention is a device according to the preamble of To design claim 1 so that the positioning of each individual Calculator is detectable.

Die Lösung der Aufgabe gestaltet sich nach den Merkmalen des Patentanspruchs 1. Hierbei ist von besonderer Bedeutung, daß die Rechenstäbe mit einer hinteren Auflageschiene 30 versehen sind, an die sie nicht fest angekoppelt sind, deren Lage aber die hintere Position der Rechenstäbe bestimmt und über deren Position die Lage auch der Rechenstäbe erfaßbar ist. Dazu ist an der Schiene ein einfacher Sensor angebracht, der deren hintere Lage erfaßt. Insbesondere durch eine Anfederung der Schiene kann der Anschlag jedes einzelnen Rechenstabes abgetastet werden. The solution to the problem is based on the features of the claim 1. It is particularly important that the rakes with a rear Support rail 30 are provided, to which they are not firmly coupled, the Position determines the rear position of the slide bars and their position the position of the slide bars can be detected. This is an easy one on the rail Sensor attached, which detects their rear position. In particular through a Springing the rail can stop every single slide rule be scanned.

In Figur 1 ist in Verbindung mit einer bogenverarbeitenden Maschine 1 ein Bogenanleger 2 dargestellt. An dem Bogenanleger 2 ist eine Non-Stop-Einrichtung 3 so angebracht, daß sie in den Bogenanleger 2 an Hubschienen 8 integriert ist. Die Hubschienen 8 sind an der Stirnseite des Bogenanlegers 2 von der bogenverarbeitenden Maschine 1 abgewandt angeordnet. Die Non-Stop-Einrichtung 3 kann mittels eines Hubwerkes 5 an den Hubschienen 8 auf- und abbewegt werden. Im Bogenanleger 2 wird ein Bogenstapel S verarbeitet. Zur Verarbeitung wird mittels einer Vereinzelungseinrichtung 4 von der Oberseite des Bogenstapels S ein Schuppenstrom von Bogen erzeugt wird. Der Schuppenstrom von Bogen wird über einen sogenannten Bändertisch 20 der bogenverarbeitenden Maschine 1 zugeführt. In Figure 1 is in connection with a sheet processing machine 1 Sheet feeder 2 shown. On the sheet feeder 2 is a non-stop device 3 attached so that it is integrated in the sheet feeder 2 on lifting rails 8. The lifting rails 8 are on the front side of the sheet feeder 2 from the sheet processing machine 1 is arranged facing away. The non-stop facility 3 can by means of a lifting mechanism 5 on the lifting rails 8 and be moved. A sheet stack S is processed in sheet feeder 2. to Processing is carried out by means of a separating device 4 from the top of the Sheet stack S a shingled stream of sheets is generated. The stream of scales von Bogen is used on a so-called belt table 20 of the sheet processing Machine 1 fed.

Die in den Bogenanleger 2 integrierte Non-Stop-Einrichtung 3 weist einen Rahmen 6 auf, in dem Tragstäbe 7 längsverschiebbar geführt sind. Die Tragstäbe 7 sind beispielsweise als einzeln angetriebene Tragstäbe 7 ausgeführt. Sie sind aus einer hinteren Position in eine vordere Positon bewegbar. Die hintere Position ist diejenige, in der die Tragstäbe 7 sich außerhalb des Stapelbereiches des Bogenanlegers 2 befinden. Die vordere Position ist diejenige, in der die Tragstäbe 7 sich innerhalb des Stapelbereiches des Bogenanlegers 2 befinden. Bei der Anordnung in der hinteren Position liegen die Tragstäbe 7 auf einer hinteren Auflageschiene 30 auf.The non-stop device 3 integrated in the sheet feeder 2 has a frame 6 on, in the support rods 7 are guided longitudinally. The support rods 7 are for example designed as individually driven support rods 7. You are from one rear position movable to a front position. The back position is the one in which the support rods 7 are outside the stacking area of the Sheet feeder 2 are located. The front position is the one in which the support rods 7 are located within the stacking area of the sheet feeder 2. In the Arranged in the rear position, the support rods 7 lie on a rear Support rail 30 on.

In Figur 2 ist die Anordnung dieser hinteren Auflageschiene 30 näher dargestellt. Hierbei ist die hintere Auflageschiene 30 in dem Rahmen 6 derart angeordnet, daß sie in Gleitschienen 10 längsverschieblich geführt wird. Die hintere Auflageschiene 30 ist gegen einen angefederten Anschlag 31 positioniert. Weiterhin ist die hintere Auflageschiene 30 mit einer Geradführung in Form eines Kettentriebes verbunden. Der Kettentrieb besteht aus zwei Ketten 32, die starr über eine Welle 33 gekoppelt sind, wobei in dem unteren Trum der Kette 32 die hintere Auflageschiene 30 eingespannt ist.The arrangement of this rear support rail 30 is shown in more detail in FIG. Here, the rear support rail 30 is arranged in the frame 6 such that it is guided longitudinally displaceably in slide rails 10. The rear support rail 30 is positioned against a spring-loaded stop 31. Furthermore, the rear one Support rail 30 connected to a straight guide in the form of a chain drive. The chain drive consists of two chains 32, which are rigidly coupled via a shaft 33 are, in the lower run of the chain 32, the rear support rail 30th is clamped.

Die hintere Auflageschiene 30 ist so aufgebaut, daß sie eine hintere Anschlagleiste 34 und eine untere Auflagefläche 35 aufweist. Die Vorderseite ist im Bereich zur unteren Auflagefläche 35 hin angeschrägt. Die Tragstäbe 7, von denen einer hier gezeigt ist, weisen an ihrer hinteren Unterkante ebenfalls eine Anschrägung 40 auf. Beim Auflaufen des Tragstabes 7 an der hinteren Auflageschiene 30 ist so eine kontinuierliche Bewegung ohne Hemmung an einer Kante möglich.The rear support rail 30 is constructed so that it is a rear Stop bar 34 and a lower bearing surface 35. The front is beveled in the area towards the lower bearing surface 35. The support rods 7, from one of which is shown here also has one on its rear lower edge Bevel 40 on. When the support rod 7 hits the rear Support rail 30 is thus a continuous movement without inhibition on one Edge possible.

In Figur 2 ist weiterhin dargestellt, daß ein Tragstab 7 mit einem Mitnahmebolzen versehen sein kann. Dieser Mitnahmebolzen 41 kann in einen Transporthaken 36 eingreifen, der mit der hinteren Auflageschiene 30 verbunden ist. Beim Verschieben des Tragstabes 7 nach vorne kann so der Tragstab 7 die hintere Auflageschiene 30 über den Transporthaken 36 mitnehmen. Hierbei wird die Geradführung der hinteren Auflageschiene 30 durch die Ketten sichergestellt. Der Transporthaken 36 weist ausreichend großes Spiel auf, sodaß die Mitnahmefunktion erst nach Anlauf aller Tragstäbe 7 beginnt. Vorstellbar ist auch ein gemeinsames Vorschieben aller Tragstäbe über die hintere Auflageschiene 30.In Figure 2 it is also shown that a support rod 7 with a driving pin can be provided. This driving pin 41 can be in a transport hook 36 engage, which is connected to the rear support rail 30. At the Moving the support rod 7 forward, the support rod 7 can the rear Take the support rail 30 over the transport hook 36. Here, the Straight guidance of the rear support rail 30 ensured by the chains. The Transport hook 36 has a sufficiently large game, so that the Driving function only begins after all support rods 7 have started. It is also conceivable a common advancement of all support rods over the rear support rail 30.

In Figur 3 ist die gesamte Anordnung von der Oberseite aus dargestellt. Hierbei ist erkennbar, daß die hintere Auflageschiene 30 in Gleitschienen 10 am Rahmen 6 angeordnet ist. Weiterhin ist der Kettentrieb 32, 33 zur Geradführung der hinteren Auflageschiene 30 an dem Rahmen 6 dargestellt. Weiterhin sind die gefederten Anschläge 31 für die rückwärtige Positionierung der hinteren Auflageschiene 30 gezeigt. Die Tragstäbe 7 liegen alle an der hinteren Anschlagleiste 34 auf der Auflageschiene 30 an. Weiterhin ist am Rahmen 6 von außen ein Endlage-Sensor 12 angeordnet. Er ist auf eine Hinterkante einer Gleitführung 11 der Auflageschiene 30 ausgerichtet und tastet deren Vorhandensein ab.In Figure 3, the entire arrangement is shown from the top. Here is recognizable that the rear support rail 30 in slide rails 10 on the frame 6th is arranged. Furthermore, the chain drive 32, 33 for straight guidance of the rear Support rail 30 shown on the frame 6. Furthermore, the sprung Stops 31 for the rear positioning of the rear support rail 30 shown. The support rods 7 are all on the rear stop bar 34 on the Support rail 30 on. Furthermore, there is an end position sensor on the frame 6 from the outside 12 arranged. It is on a trailing edge of a sliding guide 11 Support rail 30 aligned and senses their presence.

Wenn die hintere Auflageschiene 30 mittels der Tragstäbe 7 zurückgeschoben wird oder die Tragstäbe 7 bei der Zugbewegung aus dem Stapelbereich an der hinteren Auflageschiene 30 anschlagen, kann mittels des genannten Endlage-Sensors 12 die Endlageposition bzw. eine Bewegung an der hinteren Auflageschiene 30 erkannt werden. Damit ist sowohl das Erreichen der rückwärtigen Position der Auflageschiene 30 selbst als auch das Erreichen der Tragstäbe 7 am Anschlag auf der Auflageschiene 30 erkennbar.When the rear support rail 30 is pushed back by means of the support rods 7 is or the support rods 7 during the pulling movement from the stack area on the can strike the rear support rail 30 by means of the end position sensor mentioned 12 the end position or a movement at the rear Support rail 30 can be recognized. This is both reaching the rear position of the support rail 30 itself as well as reaching the Support rods 7 can be seen at the stop on the support rail 30.

In Figur 4 ist schließlich die vordere Position der Tragstäbe 7 dargestellt. Hierbei ist die Führung der Tragstäbe 7 an Einzelantrieben 42 angedeutet. Die Einzelantriebe 42 sind beispielsweise Elektromotore, die in einer trogförmigen Quertraverse 42 befestigt sind. Von den Einzelantrieben 42 angetrieben, greifen Zahnräder 44 seitlich in die Tragstäbe 7 ein. Die Tragstäbe 7 sind dazu in der Form von Zahnstangen ausgebildet und werden unterhalb der Quertraverse 43 in einer Führung 45 angeordnet, mittels derer sie seitlich und in der Höhe positioniert und möglichst reibungsarm geführt werden. Zusätzlich sind die Tragstäbe 7 noch in einer weiteren, hier nicht dargestellten, vorderen Auflageschiene geführt, die der Lastaufnahme bei der Übernahme des Reststapels dienen.
In Figur 4 ist die vordere Position der Tragstäbe 7 derart dargestellt, daß sichtbar wird, wie weit die hintere Auflageschiene 30 mit den Tragstäben 7 nach vorne gefahren werden kann. Sie befindet sich nun in der Nähe der Quertraverse 43. Dazu ist die hintere Auflageschiene 30 am Kettentrieb 32, 33 bis zu dessen vorderer Endlage vorbewegt. Es ist auch erkennbar, daß beispielsweise der hier dargestellte Tragstab 7 die hintere Auflageschiene 30 mittels des in Figur 2 beschriebenen Transporthakens 36, der hier nicht gezeigt ist, nach vorne gezogen haben kann.
Finally, the front position of the support rods 7 is shown in FIG. The guidance of the support rods 7 on individual drives 42 is indicated. The individual drives 42 are, for example, electric motors which are fastened in a trough-shaped cross member 42. Driven by the individual drives 42, gearwheels 44 engage laterally in the support rods 7. The support rods 7 are designed in the form of toothed racks and are arranged below the crossbar 43 in a guide 45, by means of which they are positioned laterally and in height and are guided with as little friction as possible. In addition, the support rods 7 are guided in a further, front support rail, not shown here, which serve to carry the load when the remaining stack is taken over.
In Figure 4, the front position of the support rods 7 is shown such that it is visible how far the rear support rail 30 can be moved forward with the support rods 7. It is now in the vicinity of the crossbar 43. For this purpose, the rear support rail 30 on the chain drive 32, 33 is advanced to its front end position. It can also be seen that, for example, the support rod 7 shown here can have pulled the rear support rail 30 forward by means of the transport hook 36 described in FIG. 2, which is not shown here.

Die vordere Position muß nun mittels weiterer Mittel für jedem Tragstab 7 selbst ebenfalls erfaßt werden. Jeder Tragstab 7 ist dazu mit einer Tast-Nut 46 versehen, die in dessen Oberseite angebracht ist. In der Quertraverse 43 der Einzelantriebe 42 ist ein Einschub-Sensor 13 eingesetzt, der auf die Oberseite der Tragstäbe 7 gerichtet ist. Beim Ankommen der Tast-Nut 46 im Bereich des Einschub-Sensors 13 wird diese Position erfaßt, und der entsprechende Einzelantrieb 42 kann stillgesetzt werden. Hiermit wird sichergestellt, daß die Tragstäbe 7 alle ausreichend weit in die für den Stapelwechsel erforderliche ausgefahrener Position in den Bereich des Bogenstapels S eingeschoben werden. Diese Position wird unabhängig von ggf. an den Einzelantrieben 42 angeordneten Wegmessystemen überwacht. The front position must now itself by means of further means for each support rod 7 also be recorded. For this purpose, each support rod 7 is provided with a tactile groove 46, which is attached in the top. In the crossbar 43 of the individual drives 42, an insertion sensor 13 is inserted, which is on the top of the support rods 7 is directed. When the tactile groove 46 arrives in the area of the insertion sensor 13 this position is detected, and the corresponding single drive 42 can to be stopped. This ensures that the support rods 7 all sufficiently far into the extended position required for the stack change are inserted into the area of the sheet stack S. This position will regardless of any distance measuring systems arranged on the individual drives 42 supervised.

Mit den beschriebenen Vorrichtungen lassen sich die Positionen der Tragstäbe 7 sowohl in der eingeschobenen als auch in der aus dem Stapelbereich gezogenen Position ausreichend überwachen. Die Ausführung ist sehr einfach.With the devices described, the positions of the support rods 7 can be both in the inserted and in the pulled out of the stacking area Monitor the position sufficiently. The execution is very simple.

Der Ablauf der Bewegungen der Tragstäbe läßt sich mit Hilfe der Sensoren 12, 13 wie folgt überwachen:The sequence of the movements of the support rods can be determined with the help of sensors 12, 13 monitor as follows:

In Normalposition sind die Tragstäbe in ausgezogener Position hinter dem Stapelbereich im Rahmen 6 angeordnet und liegen dabei auf der vorderen Auflageschiene und der hinteren Auflageschiene 30 auf. Zum Einfahren werden alle Tragstäbe 7 gleichzeitig und über den Transporthaken 36 verbunden gemeinsam mit der hinteren Auflageschiene 30 in den Stapelbereich eingefahren. Das Erreichen der vorderen Position wird über die Einschub-Sensoren 13 auf der Quertraverse 43 erfaßt. Damit ist sichergestellt, daß unabhängig von der Funktion eines einzelnen der Einzelantriebe 42 die richtige Einschubposition auch bei Antriebsschlupf oder Langsamlauf erreicht wird. Es sind dazu auch kein weiteren separaten Anschläge oder sonstigen Mittel erforderlich.In the normal position, the support rods are in the extended position behind the Stacking area arranged in the frame 6 and lie on the front Support rail and the rear support rail 30. To be retracted all support rods 7 connected simultaneously and via the transport hook 36 retracted into the stacking area together with the rear support rail 30. Reaching the front position is via the insertion sensors 13 on the Crossbar 43 detected. This ensures that regardless of the function of a single one of the individual drives 42 also the correct insertion position Traction slip or slow speed is reached. There are also no other ones separate stops or other means required.

Beim Ziehen der Tragstäbe 7 zum Vereinigen von Reststapel und neuem Bogenstapel S wird zunächst nur ein Teil der Tragstäbe 7 zurückgefahren. Beispielsweise werden zu Beginn zwei innere Tragstäbe 7 zuerst gezogen. Diese Tragstäbe 7 schieben die hintere Auflageschiene 30 mittels des Kettentriebes 32, 33 in die rückwärtige Position bis gegen die gefederten Anschläge 31. Die Endlage-Sensoren 12 am hinteren Ende des Rahmens 6 erfassen diese Position und setzen die Einzelantriebe 42 still.When pulling the support rods 7 to combine the rest of the stack and new Sheet stack S is initially moved back only a part of the support rods 7. For example, two inner support rods 7 are first drawn at the beginning. This Support rods 7 push the rear support rail 30 by means of the chain drive 32, 33 in the rear position up to the spring-loaded stops 31. Die End position sensors 12 at the rear end of the frame 6 detect this position and shut down the individual drives 42.

Im weiteren Ablauf werden nun erst die weiteren Tragstäbe 7 zeitlich versetzt, z.B. symmetrisch von der Mitte aus nach außen und ggf. in zwei Höhenstufen getrennt voneinander, aus dem Stapelbereich gezogen und jeweils bis gegen die hintere Auflageschiene 30 gefahren. Diese hintere Endlage jedes Tragstabes 7 wird wiederum ebenfalls über den seitlichen Endlagen-Sensor 12 mittels der hinteren Auflageschiene 30 erfaßt. Dies erfolgt dadurch, daß bei Anlaufen der Tragstäbe 7 an der hinteren Auflageschiene 30 diese gegen den gefederten Anschlag 31 bewegt und die Verlagerung von dem Endlage-Sensor 12 erfaßt wird. Dann ist der jeweilige Einzelantrieb 42 stillzusetzen. Damit wird über ganz einfache Mittel eine gemeinsame Erfassung einer Endlage ermöglicht, obwohl die Tragstäbe 7 alle einzeln angetrieben sind.In the further process, the further supporting rods 7 are only shifted in time, e.g. symmetrically outwards from the center and, if necessary, separated into two height levels from each other, drawn from the stacking area and up to the rear Support rail 30 moved. This rear end position of each support rod 7 is again also via the lateral end position sensor 12 by means of the rear one Support rail 30 is detected. This is done in that when the support rods 7 start up on the rear support rail 30 against the spring-loaded stop 31st moved and the displacement of the end position sensor 12 is detected. Then it is to stop each individual drive 42. This is a very simple means common detection of an end position, although the support rods 7 all are individually driven.

Die Ausführung in den Darstellungen nach Figur 2 bis 4 kann dahingehend verändert werden, daß die hintere Auflageschiene 30 nicht mittels der Tragstäbe 7 in die vordere Position mitgenommen wird. Die hintere Auflageschiene 30 kann auch über einen eigenen Antrieb an dem Kettentrieb 32, 33 in dieser vordere Position gefahren werden, wobei damit auch mittels der hintere Auflageschiene 30 die Tragstäbe 7 gemeinsam vorgeschoben werden könnten ohne deren Einzelantriebe 42 zu benutzen. Weiterhin ist es möglich, die Erfassung des Anschlags eines Tragstabes 7 an der hinteren Auflageschiene 30 in diese selbst zu verlegen, so daß beispielsweise die hintere Anschlagleiste 34 auf der Auflageschiene 30 die gemeinsame Anlage der Tragstäbe 7 erfassen würde. Dazu kann eine elektrische Kontaktierung verwendet werden. Schließlich ist es auch möglich, die vordere Lage der Tragstäbe 7 über eine gemeinsame Lichtschranke als einzigen Sensor in Querrichtung zu erfassen, wobei die Tast-Nuten 46 dann entsprechend auszubilden sind.The embodiment in the representations according to FIGS. 2 to 4 can do this be changed so that the rear support rail 30 is not by means of the support rods 7th is taken to the front position. The rear support rail 30 can also via its own drive on the chain drive 32, 33 in this front Position can be moved, whereby also by means of the rear support rail 30th the support rods 7 could be advanced together without their Single drives 42 to use. It is also possible to record the Stop of a support rod 7 on the rear support rail 30 in this itself to lay, so that for example the rear stop bar 34 on the Support rail 30 would capture the common contact of the support rods 7. To electrical contacting can be used. After all, it is possible, the front position of the support rods 7 via a common light barrier to be detected as the only sensor in the transverse direction, the keying grooves 46 then are to be trained accordingly.

Die Ausführung der einzelnen Merkmale der Erfindung ist nicht auf die konkret genannten Ausführungsbeispiele beschränkt, sondern erfasst auch weitere Lösungsmöglichkeiten sinngemäß. So kann mit der hinteren Auflageschiene 30 eine Abdeckung für die Tragstäbe 7 verbunden werden. Wenn diese als Rollo ausgeführt ist, deckt sie die Tragstäbe 7 in jeder Arbeitsposition ab und stellt eine Sicherung gegen Eingriff in den Bewegungsbereich dar. The implementation of the individual features of the invention is not specific to the limited embodiments, but also captures others Possible solutions analogously. So can with the rear support rail 30th a cover for the support rods 7 are connected. If this as a roller blind is executed, it covers the support rods 7 in each working position and provides one Securing against interference in the range of motion.
