Jede Wechselvorrichtung 12 weist einen Tragarm 14 auf, der an einem oberen Ende um eine in Schienenlängsrichtung verlaufende Schwenkachse 15 verschwenkbar ist, während ein unteres Ende 16 mit einer Transportplatte 17 verbunden ist.To replace the intermediate layers 2, two changing devices 12 are provided which are each displaceable by a displacement drive 13 relative to the tool frame 6 in the rail longitudinal direction. Each changing device 12 has a support arm 14, which is pivotable at an upper end about a pivot axis 15 extending in the longitudinal direction of the rail, while a lower end 16 is connected to a transport plate 17.

Der Tragarm 14 weist einen Anschlag 19 auf, der nach Anlage an die Schwelle 4 für eine Freigabe einer Relativverschiebung zwischen Werkzeugrahmen 6 und der Wechselvorrichtung 12 in Schienenlängsrichtung ausgebildet ist. Der Tragarm 14 ist durch einen Antrieb 20 für eine Änderung der Distanz zwischen Schwenkachse 15 und der Transportplatte 17 teleskopartig verlängerbar.The support arm 14 has a stop 19, which is formed after contact with the threshold 4 for releasing a relative displacement between the tool frame 6 and the changing device 12 in the rail longitudinal direction. The support arm 14 is telescopically extendable by a drive 20 for a change in the distance between the pivot axis 15 and the transport plate 17.

Die Transportplatte 17 ist (s. Fig. 5) - bezüglich der Schienenlängsrichtung - an einem ersten Ende 21 mit dem unteren Ende 16 des Tragarmes 14 und an einem zweiten Ende 22 mit einer Abstreifeinrichtung 23 verbunden. Diese ist aus relativ zu einer Transportebene 24 (Fig. 4) der Transportplatte 17 höhenverstellbaren Krallen 25 gebildet, die durch einen nicht näher dargestellten Antrieb um eine in Schwellenlängsrichtung verlaufende Achse 26 verschwenkbar sind.The transport plate 17 is (s. Fig. 5 ) - with respect to the rail longitudinal direction - connected at a first end 21 to the lower end 16 of the support arm 14 and at a second end 22 with a stripping device 23. This is from relative to a transport plane 24 ( Fig. 4 ) of the transport plate 17 height-adjustable claws 25 are formed, which are pivotable by a drive, not shown, about a 26 extending in the threshold longitudinal axis.

Eine Halteeinrichtung 27 der Transportplatte 17 weist eine Anzahl von Saugöffnungen 28 für ein Ansaugen und Transportieren der Zwischenlage 2 auf. Zwischen den beiden Wechselvorrichtungen 12 ist ein Plattenspeicher 29 mit dem Werkzeugrahmen 6 verbunden.A holding device 27 of the transport plate 17 has a number of Suction openings 28 for sucking and transporting the intermediate layer 2. Between the two changing devices 12, a disk storage 29 is connected to the tool frame 6.

Im Folgenden wird die Funktionsweise der Erfindung näher beschrieben. Die Vorrichtung 1 wird durch eine nicht näher dargestellte Zugeinheit kontinuierlich in einer Arbeitsrichtung 30 gezogen, wobei die Heberollen 11 an die Schienen 3 angelegt sind. Diese werden unter Beaufschlagung der Hebeantriebe 10 mitsamt dem Werkzeugrahmen 6 von den darunter liegenden Schwellen 4 distanziert, wobei sich die Hebefahrwerke 9 auf den Schwellen 4 abstützen. Die beiden Wechselvorrichtungen 12 befinden sich in einer bezüglich des Werkzeugrahmens 6 vorderen, in Fig. 1a dargestellten Arbeitsposition.The operation of the invention will be described in more detail below. The device 1 is pulled continuously by a tractor unit not shown in a working direction 30, wherein the lifting rollers 11 are applied to the rails 3. These are distanced under the action of the lifting drives 10 together with the tool frame 6 of the underlying thresholds 4, wherein the lifting chassis 9 are supported on the thresholds 4. The two changing devices 12 are located in a front relative to the tool frame 6, in Fig. 1a illustrated working position.

Durch einen ein Schienenbefestigungsmittel bzw. eine Rippenplatte 37 detektierenden Sensor 32 wird ein im Folgenden beschriebener Arbeitszyklus gestartet. Der Tragarm 14 wird mit Hilfe eines Antriebes 31 von der in Fig. 2 mit strichpunktierter Linie dargestellten Position in Richtung zur Schiene 3 verschwenkt, wobei eine vom Plattenspeicher 29 an die Transportplatte 17 angesaugte Zwischenlage 2 mitgenommen wird. Der Tragarm 14 befindet sich dabei zwischen zwei Schwellen 4 (s. Fig. 1a).By means of a sensor 32 detecting a rail fastening means or a ribbed plate 37, a working cycle described below is started. The support arm 14 is by means of a drive 31 of the in Fig. 2 pivoted with dash-dotted line position in the direction of the rail 3, wherein a sucked from the disk storage 29 to the transport plate 17 intermediate layer 2 is taken. The support arm 14 is located between two sleepers 4 (s. Fig. 1a ).

Die Transportplatte 17 ist nunmehr mitsamt der Zwischenlage 2 unterhalb eines Schienenfußes 33 positioniert, wobei durch entsprechendes Zusammenwirken des Antriebes 20 und einer Schraubenfeder 34 ein permanentes Andrücken einer Oberseite 35 der Transportplatte 17 an den Schienenfuß 33 sicher gestellt wird.
Durch die Vorspannung der Schraubenfeder 34 wird sichergestellt, das die Transportplatte 17 mit den Keilförmigen Spitzen 38 immer unten am Schienenfuß anliegt.The transport plate 17 is now positioned together with the intermediate layer 2 below a rail foot 33, wherein by appropriate interaction of the drive 20 and a coil spring 34 is a permanent Pressing a top 35 of the transport plate 17 to the rail 33 is ensured.
By the bias of the coil spring 34 ensures that the transport plate 17 with the wedge-shaped tips 38 is always applied to the bottom of the rail.

Unter Beaufschlagung des Verschiebeantriebes 13 wird die Wechselvorrichtung 12 in Arbeitsrichtung 30 verschoben, bis der Anschlag 19 die Schwelle 4 kontaktiert. Somit befindet sich die Zwischenlage 2 exakt oberhalb ihrer Endposition, die sofort nach Auflösung des Vakuums in den Saugöffnungen 28 erreicht wird. Durch Drucklosschaltung des Verschiebeantriebes 13 kommt es in Verbindung mit der kontinuierlichen Vorwärtsbewegung des Werkzeugrahmens 6 zu einer Relativverschiebung zu diesem bzw. zu einem örtlichen Stillstand der Wechselvorrichtungen 12.Under the action of the displacement drive 13, the changing device 12 is displaced in the working direction 30 until the stop 19 contacts the threshold 4. Thus, the intermediate layer 2 is exactly above its end position, which is achieved immediately after dissolution of the vacuum in the suction openings 28. By depressurization of the displacement drive 13 occurs in conjunction with the continuous forward movement of the tool frame 6 to a relative displacement to this or to a local standstill of the changing devices 12th

Während der soeben beschriebenen Einschiebebewegung der Zwischenlage 2 in ihre Endposition erfolgt durch die abgesenkten Krallen 25 ein Anheben und Abstreifen der alten Zwischenlage 2 von der Schwelle 4 (s. Fig. 3). Sollte die alte Zwischenlage 2 am Schienenfuß 33 haften (s. strichpunktierte Linie in Fig. 3), dann erfolgt mit Hilfe von keilförmigen Spitzen 38 der Transportplatte 17 automatisch eine Mitnahme und ein Abstreifen der alten Zwischenlage 2.During the insertion movement of the intermediate layer 2 just described to its end position, the lowered claws 25 cause the old intermediate layer 2 to be lifted and removed from the threshold 4 (see FIG. Fig. 3 ). Should the old intermediate layer 2 adhere to the rail foot 33 (see dash-dotted line in FIG Fig. 3 ), then carried out with the help of wedge-shaped tips 38 of the transport plate 17 automatically entrainment and stripping the old liner. 2

Nach erfolgter Ablage der neuen Zwischenlage 2 auf die Schwelle 4 bzw. Rippenplatte 37 wird die Wechselvorrichtung 12 mit Hilfe des Verschiebeantriebes 13 kurz entgegen der Arbeitsrichtung 30 zurück bewegt (s. Fig. 1 b), um anschließend den Tragarm 14 zwischen zwei Schwellen 4 zum Ansaugen der nächsten Zwischenlage 2 zum Plattenspeicher 29 verschwenken zu können.After the storage of the new intermediate layer 2 on the threshold 4 or ribbed plate 37, the changing device 12 by means of the displacement drive 13 briefly moved back against the working direction 30 (s. Fig. 1 b) in order then to pivot the support arm 14 between two sleepers 4 for sucking the next intermediate layer 2 to the disk storage 29 can.

Dabei sind die Krallen 25 zurückgeschwenkt. Die Transportplatte 17 ist von der abgelegten Zwischenlage 2 geringfügig distanziert (s. Fig. 4), um ein Abstreifen derselben zu vermeiden.The claws 25 are swung back. The transport plate 17 is slightly distanced from the deposited intermediate layer 2 (s. Fig. 4 ) to avoid stripping them.

Zur Einleitung eines neuen Arbeitszyklus werden beide Wechselvorrichtungen 12 unter Beaufschlagung der Verschiebeantriebe 13 in ihre vordere Endposition (Fig. 1a) relativ zum kontinuierlich vorwärts fahrenden Werkzeugrahmen 6 vorgeschoben.In order to initiate a new work cycle, both changing devices 12 are moved into their front end position (under the action of the displacement drives 13). Fig. 1a ) advanced relative to the continuously advancing tool frame 6.

Abweichend von der soeben beschriebenen Art kann die Halteeinrichtung 27 beispielsweise auch in Form von Klammern zum temporären Festklemmen der Zwischenlage 2 ausgebildet sein. Ebenso gibt es bezüglich der Schienenhebevorrichtung 18 verschiedene Gestaltungsmöglichkeiten. Der Arbeitszyklus kann auch entgegen der Arbeitsrichtung 30 begonnen und in Arbeitsrichtung beendet werden. Ebenso kann die Wechselvorrichtung 12 derart gestaltet sein, dass mit der Halteeinrichtung 27 die alte Zwischenlage 12 entnommen und definiert abgelegt wird. Mit einer weiteren Wechselvorrichtung 12 wird anschließend in einem weiteren Arbeitsschritt eine neue Zwischenlage eingebracht.Notwithstanding the manner just described, the holding device 27 may be formed, for example, in the form of brackets for temporary clamping of the intermediate layer 2. Similarly, there are 18 different design options with respect to the rail lifting device. The working cycle can also be started counter to the working direction 30 and finished in the working direction. Likewise, the changing device 12 may be designed such that removed with the holding device 27, the old intermediate layer 12 and stored defined. With a further changing device 12, a new intermediate layer is then introduced in a further step.
