Definitions
- the present invention relates to a conveyor system for magazines of vehicles according to the preamble of claim 1.
- the system of rails in automatic magazines forms a closed circuit consisting generally of straight parts and curve parts (meander shape).
- the conveyor system of the magazine is regulated so that the vehicles are as close to one another as possible. This results in the problem that the vehicles in the straight parts are to be arranged relatively close together, while they must have in the curve parts a greater distance from each other, since the point of storage on the environment (clamp with track) a circle with a larger radius describes as the outermost point of the vehicle on the inside of the curve.
- the present invention relates to a system for transporting vehicles of a cable transport system with automatically detachable clamp in an automatically operated magazine.
- the conveyor system should allow a very compact design by a smaller distance of the driving equipment in the straight part as in the curves.
- the system should be uniform throughout the magazine and form a single closed circuit, thus comprising the straight parts and the cam parts.
- This task is performed in a conveyor system according to the characterizing part of claim 1.
- the vehicles are thus moved by segments, which in turn are connected to a continuously moving at a constant speed in one direction moving chain.
- the speed of these segments respectively the chain corresponds to that in the curves.
- the problem of cornering is again solved by a distance control.
- the movement of the vehicles in the straight part is interrupted at intervals, by the shape of the individual segments is changed so that driving is not possible.
- the time interval of the interruption is so great that in the curve part of the vehicles is transported to a sufficiently large distance to the following vehicle. If this is the case, the following vehicle can be introduced into the curve.
- the speed control here is due to the fact that the averaged over a period of time in the straight part is less than in the curve part. Since the speed of the segments is relatively low, one can speak here of a sudden transition from one interval to another.
- FIG. 5 The illustrated graphic illustrates the regulation of the vehicle distance by means of the transport intervals:
- the vehicles can be transported within the magazine with only a single conveyor system, which transports the vehicles in both the straight pieces and in the curved pieces, ensuring the sufficient distance of the vehicles from each other in the curves and the Distance in the straight pieces can be kept low.
- the system therefore requires only a single drive.
- the system is easily adaptable to different sizes of magazines.
- the real novelty of the invention is that for the transport of vehicles in the track system of a magazine only a single conveyor system is necessary and that the solution of the cornering is not in the curve, but in the form of intermittent interruptions of onward transport in the straight part.
- terminals 9/10 of cable-drawn vehicles which are rollingly mounted on rails 11 of the magazine, are transported on via a conveyor system 2).
- the conveyor system consists of a chain 16 to which fasteners 14/19 are attached at regular intervals.
- a driver 6/8 is articulated via a rotary joint 15/20, each of which at the upper end, rotatably mounted, carries a deflection roller 5/7.
- These deflection rollers are mounted with respect to an axis of symmetry 12 of the driver from one driver to the next alternately right and left.
- Fig. 1 and 2 show a in FIG. 5 outgoing transport interval.
- the drivers are 6/8 in the engaged position.
- the driver 6/8 are held by a tension spring 22/23 in its driving position and a stop 13/18 stops caused by the tension spring rotational movement of the driver 6/8.
- Fig. 3 and 4 show a break interval.
- ramps 1/2/3/4 are analogous to the deflection rollers also with respect to the axis of symmetry of the driver alternately right and left thereof and arranged exactly on the trajectory of the deflection rollers such that the end edges of a ramp and the following are in line. If a deflection roller passes a ramp, it is deflected, whereby the driver is rotated about the pivot in such a way that the driver passes over the clamp and thus the further transport is interrupted. Due to the alternating arrangement of the ramps and the deflection rollers, this process is repeated only with every second driver. The vehicles move so only at intervals.

Description
Die vorliegende Erfindung bezieht sich auf ein Fördersystem für Magazine von Fahrzeugen gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a conveyor system for magazines of vehicles according to the preamble of
Bei automatisch betriebenen Magazinen von Seilförderanlagen mit automatisch kuppelbarer Klemme oder aber auch fixer, vom Seil abnehmbarer Klemme werden die Fahrzeuge im Magazin mittels eines Fördersystems weitertransportiert, bis sich alle Fahrzeuge im Magazin befinden. Da das Fahrzeug an seiner Klemme rollend an die Umgebung, wie etwa Laufschienen, gelagert ist, greift das Transportsystem an der Klemme oder an einem anderem, am Fahrzeug festliegenden Teil, wie an der Aufhängung, bzw. am Fahrzeug selbst an.In automatically operated magazines of cable transport systems with automatically detachable clamp or even fixed, detachable from the rope clamp the vehicles are transported in the magazine by means of a conveyor system until all vehicles are in the magazine. Since the vehicle is mounted on its terminal rolling to the environment, such as rails, the transport system attacks on the terminal or other, fixed to the vehicle part, such as on the suspension, or on the vehicle itself.
Das System der Laufschienen in automatischen Magazinen bildet einen geschlossenen Kreislauf bestehend im allgemeinen aus geraden Teilen und Kurventeilen (Mäanderform). Um die Größe des Magazins so gering wie möglich zu halten, ist das Fördersystem des Magazins so geregelt, dass die Fahrzeuge möglichst einen kleinen Abstand zueinander haben. Hieraus resultiert die Problematik, dass die Fahrzeuge in den geraden Teilen relativ eng beieinander anzuordnen sind, während sie in den Kurventeilen einen größeren Abstand zueinander haben müssen, da der Punkt der Lagerung an der Umgebung (Klemme mit Laufschiene) einen Kreis mit größerem Radius beschreibt als der äußerste Punkt des Fahrzeugs an der Innenseite der Kurve.The system of rails in automatic magazines forms a closed circuit consisting generally of straight parts and curve parts (meander shape). In order to keep the size of the magazine as small as possible, the conveyor system of the magazine is regulated so that the vehicles are as close to one another as possible. This results in the problem that the vehicles in the straight parts are to be arranged relatively close together, while they must have in the curve parts a greater distance from each other, since the point of storage on the environment (clamp with track) a circle with a larger radius describes as the outermost point of the vehicle on the inside of the curve.
Eine Lösungsmöglichkeit wäre der Betrieb von, hinsichtlich der Verfahrgeschwindigkeiten, unterschiedlichen Systemen im geraden Teil und im Kurventeil. Diese Systeme müssen jedoch gut aufeinander abgestimmt sein. Vor allem bei der Übergabe des Fahrzeugs vom geraden Teil in das Kurventeil und umgekehrt besteht die Gefahr von Unstetigkeiten im Bewegungsablauf.One solution would be the operation of, in terms of travel speeds, different systems in the straight part and in the curve part. However, these systems must be well matched. Especially when transferring the vehicle from the straight part to the curve part and vice versa, there is a risk of discontinuities in the movement sequence.
Aufgrund der unterschiedlichen Magazingrößen und Ausführungen muss das Transportsystem stets angepasst werden. Dies führt bei jedem Projekt, das ein Magazin beinhaltet, zu einer einmaligen Anfertigung des Fördersystems, woraus Zeitverzögerungen und Kostenerhöhung resultieren.Due to the different magazine sizes and designs, the transport system must always be adapted. For each project that includes a magazine, this results in a one-off production of the conveyor system, resulting in time delays and cost increases.
Die vorliegende Erfindung betrifft ein System zur Beförderung von Fahrzeugen einer Seilförderanlage mit automatisch kuppelbarer Klemme in einem automatisch betriebenen Magazin. Das Fördersystem soll eine sehr kompakte Bauweise durch einen geringeren Abstand der Fahrbetriebsmittel im geraden Teil als in den Kurven erlauben.The present invention relates to a system for transporting vehicles of a cable transport system with automatically detachable clamp in an automatically operated magazine. The conveyor system should allow a very compact design by a smaller distance of the driving equipment in the straight part as in the curves.
Das System soll über das gesamte Magazin einheitlich sein und einen einzigen geschlossenen Kreislauf bilden, somit die geraden Teile und die Kurventeile umfassen.The system should be uniform throughout the magazine and form a single closed circuit, thus comprising the straight parts and the cam parts.
Diese Aufgabe wird in einem Fördersystem gemäß dem kennzeichnenden Teil des Anspruchs 1 gelöst.This task is performed in a conveyor system according to the characterizing part of
Die Fahrzeuge werden damit durch Segmente fortbewegt, die ihrerseits mit einer sich kontinuierlich mit konstanter Geschwindigkeit in eine Richtung bewegenden Kette verbunden sind. Die Geschwindigkeit dieser Segmente respektive der Kette entspricht der in den Kurven.The vehicles are thus moved by segments, which in turn are connected to a continuously moving at a constant speed in one direction moving chain. The speed of these segments respectively the chain corresponds to that in the curves.
Die Problematik der Kurvenfahrt wird wieder durch eine Abstandsregelung gelöst. Die Fortbewegung der Fahrzeuge im geraden Teil wird dabei intervallweise unterbrochen, indem die Gestalt der einzelnen Segmente so verändert wird, dass eine Mitnahme nicht möglich ist.The problem of cornering is again solved by a distance control. The movement of the vehicles in the straight part is interrupted at intervals, by the shape of the individual segments is changed so that driving is not possible.
Das zeitliche Intervall der Unterbrechung ist dabei so groß, dass im Kurventeil die Fahrzeuge auf eine genügend große Distanz zum nachfolgenden Fahrzeug transportiert wird. Ist dies der Fall, kann das nachfolgende Fahrzeug in die Kurve eingeleitet werden. Die Regelung über die Geschwindigkeit ist hier darauf zurückzuführen, dass die über einen Zeitraum gemittelte Geschwindigkeit im geraden Teil geringer ist als im Kurventeil. Da die Geschwindigkeit der Segmente relativ gering ist, kann hier von einem sprunghaften Übergang von einem Intervall ins andere gesprochen werden. Die in
Auf diese Weise wird erreicht, dass die Anzahl der Fahrzeuge, die je Zeiteinheit irgendeine Ebene im Magazin durchfahren, immer gleich ist.In this way, it is achieved that the number of vehicles passing through each level in the magazine per unit time is always the same.
In automatischen Seilförderanlagen mit automatisch betriebenen Magazinen können die Fahrzeuge innerhalb des Magazins mit nur einem einzigen Fördersystem transportiert werden, das die Fahrzeuge sowohl in den geraden Stücken als auch in den Kurvenstücken transportiert, wobei der ausreichende Abstand der Fahrzeuge voneinander in den Kurven gewährleistet ist und der Abstand in den geraden Stücken gering gehalten werden kann.In automated ropeways with automatically operated magazines, the vehicles can be transported within the magazine with only a single conveyor system, which transports the vehicles in both the straight pieces and in the curved pieces, ensuring the sufficient distance of the vehicles from each other in the curves and the Distance in the straight pieces can be kept low.
Das System erfordert deshalb auch nur einen einzigen Antrieb.The system therefore requires only a single drive.
Der Übergang vom geraden Teil in den Kurventeil geschieht fliessend ohne Unstetigkeiten in Bewegungsablauf.The transition from the straight part to the curve part happens fluently without discontinuities in the sequence of movements.
Das System ist leicht an unterschiedliche Grössen von Magazinen anpassbar.The system is easily adaptable to different sizes of magazines.
Bestimmte Elemente dieses Fördersystems können in grossen Stückzahlen vorgefertigt und in jedem Magazin verwendet werden.Certain elements of this conveyor system can be prefabricated in large numbers and used in each magazine.
Etwaige Reparaturarbeiten sind leichter durchführbar, da eventuell nur Einzelteile ausgetauscht werden müssen.Any repair work is easier to carry out, since possibly only parts have to be replaced.
In der von der Anmelderin selbst entwickelten Lösung, übernimmt in den Kurven eine andere, im vergleich zum geraden Teil schnellere, Förderkette den Transport der Fahrzeuge (
In
Die eigentliche Neuheit der Erfindung besteht darin, dass für den Transport der Fahrzeuge in dem Laufschienensystem eines Magazins nur noch ein einziges Fördersystem notwendig ist und dass die Lösung der Kurvenfahrt nicht in der Kurve liegt, sondern in Form von intervallweisen Unterbrechungen der Weiterbeförderung im geraden Teil.The real novelty of the invention is that for the transport of vehicles in the track system of a magazine only a single conveyor system is necessary and that the solution of the cornering is not in the curve, but in the form of intermittent interruptions of onward transport in the straight part.
