Description

Die Erfindung betrifft eine Einrichtung zur Erzeugung von Schachtinformation, wobei ein mindestens über die Förderhöhe einer Aufzugskabine aufgespannter Codeträger mit Code vorgesehen ist und einer an der Aufzugskabine angeordneten Einrichtung zum Lesen und Auswerten des Codes gemäss der Definition des unabhängigen Patentanspruchs.The invention relates to a device for generating shaft information, wherein a coded carrier with code spanned at least over the conveying height of an elevator car is provided and a device arranged on the elevator car for reading and evaluating the code according to the definition of the independent patent claim.

Aus der Patentschrift EP 0 792 833 B1 ist eine Einrichtung zur Erzeugung von Schachtinformation bekannt geworden. Ein über die gesamte Förderhöhe gespanntes Stahlband dient als Träger für Magnete, die bestimmte Fahrbereiche, wie beispielsweise der Einfahrbereich auf dem Stockwerk, der Aufzugskabine markieren. Am Stahlband sind mehrere Bahnen für die Anordnung der Magnete vorgesehen. Eine an der Aufzugskabine angeordnete Leseeinrichtung mit Magnetschaltern bewegt sich bei fahrender Aufzugskabine gegenüber dem Stahlband und führt dieses mittels an einem U-förmigen Träger angeordneten Führungen. Je Trägerschenkel sind zwei Führungen vorgesehen, wobei jede Führung eine Nut zur Führung des Stahlbandes aufweist.From the patent EP 0 792 833 B1 a device for the production of shaft information has become known. A tensioned over the entire height of the steel belt serves as a carrier for magnets that mark certain driving areas, such as the retraction area on the floor of the elevator car. On the steel strip several tracks are provided for the arrangement of the magnets. A arranged on the elevator car reading device with magnetic switches moves when driving the elevator car relative to the steel strip and leads this by means arranged on a U-shaped carrier guides. Per carrier leg two guides are provided, each guide has a groove for guiding the steel strip.

Nachteilig ist, dass die Leseeinrichtung und das Stahlband der bekannten Einrichtung gross baut und dementsprechend Platz im Aufzugsschacht braucht. Ausserdem kann das Stahlband die Führungsnuten verlassen oder in den Führungsnuten klemmen.The disadvantage is that the reading device and the steel strip of the known device builds large and therefore needs space in the elevator shaft. In addition, the steel strip can leave the guide grooves or clamp in the guide grooves.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und eine Einrichtung schaffen, die einen Codeträger zur Erzeugung von Schachtinformation sicher führt.The invention aims to remedy this situation. The invention, as characterized in claim 1, solves the problem of avoiding the disadvantages of the known device and to provide a device that safely carries a code carrier for generating shaft information.

Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.Advantageous developments of the invention are specified in the dependent claims.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die Führung des Codeträgers mittels eines kostengünstigen Gehäuses machbar ist. Das Gehäuse ist aus einem Strangpressprofil hergestellt und wird mittels Boden und Deckel verschlossen. Das Strangpressprofil weist Schraubkanäle, Befestigungskanäle, als Plattenhalterung dienende Plattenkanäle und einen Kanal für eine der Führung des Codeträgers dienende Gleitführung auf. Weiter vorteilhaft ist der einfache Austausch der als Verschleissteil konzipierten, in den Kanal einschiebbaren Gleitführung. Weiter vorteilhaft ist, dass der Codeträger während der Bewegung der Aufzugskabine nicht nur sicher geführt wird, sondern auch gleichzeitig von Staub und Metallspähnen gereinigt wird. Mit dem gleichen Gehäuse kann auch ein Schachtinformationssystem ohne Führung des Codeträgers geschaffen werden. Das Gehäuse baut schlank und kann auch bei knappen Platzverhältnissen im Schacht an der Aufzugskabine angebaut werden.The advantages achieved by the invention are essentially to be seen in the fact that the leadership of the code carrier is feasible by means of a low-cost housing. The housing is made of an extruded profile and is closed by means of bottom and lid. The extruded profile has screw channels, fastening channels, plate channels serving as a plate holder, and a channel for a sliding guide serving to guide the code carrier. Also advantageous is the simple replacement of designed as a wear part, can be inserted into the channel slide. It is also advantageous that the code carrier is not only guided safely during the movement of the elevator car, but is also cleaned of dust and metal sparks at the same time. With the same housing, a shaft information system without guiding the code carrier can be created. The housing is slim and can be mounted on the elevator cab even in tight spaces in the shaft.
