Description

Die Erfindung betrifft eine Einrichtung zur Erfassung einer in seiner Längsrichtung verlaufenden Seilbewegung für ein Hebezeug, insbesondere für einen pneumatisch betriebenen Seilbalancer, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for detecting in its longitudinal direction running cable movement for a hoist, especially for a pneumatic operated rope balancer, according to the preamble of claim 1.

Aus der DE 1928683 und DE 2003837 ist jeweils ein Seilbalancer bekannt, der pneumatisch betrieben wird. Der Seilbalancer weist eine Seiltrommel auf, in der ein Kolben längsverschieblich angeordnet ist. Die Seiltrommel selbst ist mit einer Spindel drehfest verbunden, die in der Seiltrommel koaxial verläuft. Die Spindel wiederum geht durch eine am Gehäuse fest angeordnete Spindelmutter. Auf diese Weise wird erreicht, dass eine Verschiebung des Kolbens durch Gasdruckbeaufschlagung zu einer kombinierten Dreh- und Längsbewegung der Seiltrommel führt. Die Seiltrommel weist eine Seilrille für das Seil auf, dass jeweils vom Ablaufpunkt nach unten zu einem Lastaufnahmemittel geführt ist. Die Steigung der Seilrille ist so gewählt, dass sich der Ablaufpunkt des Seils jeweils an derselben Stelle des Gehäuses befindet.A rope balancer is known from DE 1928683 and DE 2003837, respectively is operated pneumatically. The rope balancer has a rope drum in which a Piston is arranged to be longitudinally displaceable. The rope drum itself is with a spindle rotatably connected, which runs coaxially in the cable drum. The spindle in turn goes by a spindle nut fixed to the housing. That way achieved that a displacement of the piston due to gas pressure a combined rotary and longitudinal movement of the rope drum. The rope drum has a rope groove for the rope that goes down from the drain point to one Load handler is guided. The slope of the rope groove is chosen so that the The drain point of the rope is located in the same place on the housing.

Weiter ist es aus der Praxis bekannt, zur schlupffreien Erfassung der Seilbewegung an einem Ende der Seiltrommel eine von der Seiltrommel angetriebene Kreisscheibe anzuordnen, die mit gleichbeabstandeten Markierungen versehen ist. Mit Drehung der Seiltrommel dreht sich die Kreisscheibe und die Markierungen bewegen sich an einem Sensor einer Sensoreinheit vorbei, welche die Markierungen beim Passieren mit dem Sensor erfasst. Die Sensoreinheit gibt als Folge der Drehbewegung der Seiltrommel unmittelbar ein jeweils korrespondierendes Ausgangssignal ab.It is also known from practice for slip-free detection of the rope movement at one end of the rope drum a circular disk driven by the rope drum to be arranged, which is provided with equally spaced markings. With rotation of the Rope drum turns the circular disc and the markings move on you Sensor of a sensor unit passing the markings when passing with the Sensor detected. The sensor unit emits as a result of the rotary movement of the cable drum immediately a corresponding output signal.

Der Nachteil dieser bekannten Lösung besteht darin, dass sie nicht robust und nicht konstruktiv einfach ist. The disadvantage of this known solution is that it is not robust and not is structurally simple.

Die Aufgabe der Erfindung besteht darin, eine konstruktiv einfache und robuste Einrichtung anzugeben, mit der schlupffrei eine Seilbewegung in Seillängsrichtung über einem Hebezeug mit einer Seiltrommel erfassbar ist.The object of the invention is a structurally simple and robust Specify the device with the slip-free rope movement in the longitudinal direction of the rope over a hoist with a rope drum.

Die Lösung dieser Aufgabe ist durch die im Anspruch 1 angegebenen Merkmale gegeben; durch die kennzeichnenden Merkmale der Unteransprüche ist die Einrichtung in vorteilhafter Weise weiter ausgestaltet.This object is achieved by the features specified in claim 1 given; by the characterizing features of the subclaims Device further advantageously configured.

Die Lösung sieht vor, dass die in der Seiltrommelmantelfläche ausgebildete Seilrille einen parallel zur Seilrille verlaufenden schraubenlinienartigen Steg bildet, dass die Markierungen längs des Stegs vorgesehen sind, und dass der Sensor derart feststehend am Gehäuses angeordnet ist, dass er dem Steg jeweils gegenüberliegend diesem zugewandt ist. Den Steg selbst als Tragelement für die Markierungen zu verwenden, führt zu einer sehr robusten Ausführung der Einrichtung. Dies ist darüber hinaus konstruktiv einfach aufgebaut, da sie lediglich einen Sensor am Gehäuse und nur am Steg befestigte Markierungen erfordert.The solution provides that the rope groove formed in the rope drum jacket surface a helical web running parallel to the cable groove forms that the Markings are provided along the web, and that the sensor is such is fixedly arranged on the housing that it is opposite the web in each case facing this. The web itself as a supporting element for the markings use leads to a very robust design of the device. This is about it also structurally simple, since it only has a sensor on the housing and only markings attached to the dock required.

Zur Erzeugung eines mit geringem Aufwand auswertbaren Ausgangssignals wird vorgeschlagen, dass die Markierungen aus einzeln angeordneten längenmäßig begrenzten Markierungselementen gebildet sind, die sich zusammen mit der Seiltrommel bewegen.To generate an output signal that can be evaluated with little effort suggested that the markings consist of individually arranged lengths limited marking elements are formed, which together with the Move the rope drum.

Einfache kontaktlos abtastbare Markierungen erhält man, wenn die Markierungen auf einem Ferritband angeordnet sind, das abwechselnd aus magnetisierten und nicht magnetisierten Bereichen gleicher Länge und gleichen Abstands besteht.Simple contactlessly scannable markings are obtained when the markings are on a ferrite tape are arranged, which are alternately magnetized and not magnetized areas of the same length and the same distance.

Eine stabile Ausführung wird sichergestellt, wenn das Ferritband ein Stahlband als Träger aufweist.A stable design is ensured if the ferrite band is a steel band Carrier has.

Um eine robustere Ausführung zu erhalten, weist der Steg eine Nut auf, in die das Stahlband eingelegt ist.In order to obtain a more robust design, the web has a groove into which the Steel band is inserted.

Die Verwendung eines Hall-Sensors als Sensor führt zu einem störsicheren und einfachen Erfassen der Markierungen, wobei erwähnt sei, dass die Anwendung von Hall-Sensoren bei Hebezeugen z.B. aus der DE 199 25 364 C2 bekannt ist. The use of a Hall sensor as a sensor leads to an interference-free and simple detection of the markings, mentioning that the use of Hall sensors for hoists e.g. is known from DE 199 25 364 C2.

Fig. 1 zeigt eine Seiltrommel 1 eines pneumatische betriebenen Seilbalancers.1 shows a cable drum 1 of a pneumatically operated cable balancer.

Nicht dargestellt ist in Fig. 1 - 3 der an sich bekannte Antrieb des Seilbalancers: In der Seiltrommel 1 ist ein Kolben längsverschieblich angeordnet. Die Seiltrommel 1 ist mit einer Spindel drehfest verbunden, die in der Seiltrommel 1 koaxial verläuft. Die Spindel wiederum ist durch eine am Gehäuse fest angeordnete Spindelmutter geführt. Dadurch wird eine Verschiebung des Kolbens durch seine Gasdruckbeaufschlagung in eine kombinierte Dreh- und Längsbewegung der Seiltrommel 1 umgesetzt.The drive of the cable balancer, which is known per se, is not shown in FIGS. 1-3 Cable drum 1, a piston is arranged to be longitudinally displaceable. The cable drum 1 is with a spindle rotatably connected, which runs coaxially in the cable drum 1. The spindle is in turn guided through a spindle nut fixedly arranged on the housing. This will cause the piston to move due to its gas pressure a combined rotary and longitudinal movement of the cable drum 1 implemented.

Die Seiltrommel 1 ist in einem nicht dargestellten Gehäuse längs verschiebbar und weist eine Seilrille 2 für ein Seil (nicht dargestellt) auf, das nach unten zu einem Lastaufnahmemittel geführt ist. Die Seilrille 2 ist schraubenlinienartig in die Seiltrommelmantelfläche 3 eingeformt. Parallel zur Seilrille 2 verläuft ein schraubenlinienartiger Steg 4. Im Steg 4 ist längs des Stegs 4 eine Nut 5 eingearbeitet, in die ein Stahlband 6 eingelegt ist. Das Stahlband 6 trägt auf seiner nach außen weisenden Oberfläche eine Ferritschicht 6a; das Stahlband 6 und die Ferritschicht 6a bilden zusammen ein sogenanntes Ferritband. Die Ferritschicht 6a besteht abwechselnd aus magnetisierten und nicht magnetisierten Bereichen gleicher Länge und Breite und gleichen Abstands. Selbstverständlich sind auch andere insbesondere längs des Ferritbandes variierende Bereichsabmessungen möglich. Der Ferritschicht 6a zugewandt befindet sich im Gehäuse jeweils an einer Stelle dem Steg 4 gegenüberliegend ein Sensor 7 in Form eines Hall-Sensors, der die passierenden elektrischen Magnetfelder der Markierungen erfaßt und in elektrische Signale umwandelt, das wiederum von der Sensoreinheit 8 über ein Kabel 9 als Ausgangssignal beispielsweise einer Steuereinheit zur Verfügung gestellt wird.The cable drum 1 is longitudinally displaceable in a housing, not shown has a rope groove 2 for a rope (not shown) that goes down to one Load handler is guided. The rope groove 2 is helical in the Cable drum surface 3 molded. A runs parallel to the groove 2 helical web 4. In web 4 there is a groove 5 along web 4 incorporated into which a steel strip 6 is inserted. The steel belt 6 carries on his outwardly facing surface a ferrite layer 6a; the steel belt 6 and the Ferrite layer 6a together form a so-called ferrite band. The ferrite layer 6a consists alternately of magnetized and non-magnetized areas of the same Length and width and equal distance. Of course there are others too In particular, varying area dimensions are possible along the ferrite strip. The The ferrite layer 6a faces the web at one point in the housing 4 opposite a sensor 7 in the form of a Hall sensor that the passing electrical magnetic fields of the markings are captured and converted into electrical signals converts, which in turn from the sensor unit 8 via a cable 9 as Output signal is made available to a control unit, for example.

Die Markierungen bestehen hierbei allgemein aus einzeln angeordneten längenmäßig begrenzten Markierungselementen. Alternativ können diese auch aus Löchern, Strichcodes, Erhebungen und Vertiefungen bestehen.The markings generally consist of individually arranged lengths limited marker elements. Alternatively, these can also be made from holes, Barcodes, surveys and in-depths exist.

Die Steigung der Seilrille ist so gewählt, dass sich der Ablaufpunkt des Seils jeweils an derselben Stelle des Gehäuses befindet.The slope of the rope groove is selected so that the rope's point of departure adjoins each other the same place of the housing.

Selbstverständlich kann es sich bei der Seiltrommel 1 auch um eine Seiltrommel eines beliebigen anderen Hebezeugs handeln. Allerdings muß sich die Seiltrommel beim Heben und Senken derart entsprechend längsverschieben, dass sich der Ablaufpunkt des Seils jeweils an derselben Stelle befindet.Of course, the cable drum 1 can also be a cable drum any other hoist. However, the rope drum must Raise and lower accordingly in such a way that the run-off point changes of the rope is always in the same place.

Auf diese Weise tastet der Sensor 7 die Markierungen auf dem Ferritband 6 ab, wenn sich die Seiltrommel 1 dreht. Bei Drehung der Seiltrommel 1 läuft das Ferritband 6 jeweils an dem Sensor 7 diesem zugewandt vorbei. In this way, the sensor 7 scans the markings on the ferrite tape 6 when the cable drum 1 rotates. When the cable drum 1 rotates, the ferrite band 6 runs each past the sensor 7 facing this.
