Derartige manuell bewegbare Gurthobel sind grundsätzlich bekannt und dienen dazu, die Deckschicht oder Teile der Deckschicht am Ende eines Fördergurtes zu entfernen. Es ist hierbei üblich, das Gurtende auf einer Stützeinrichtung gegen Verrutschen zu sichern und sodann die Bearbeitung mit dem Hobel vorzunehmen, wobei der Hobel von Hand gezogen wird. Im Allgemeinen ähnelt der Aufbau des Gurthobels einem Schreinerhobel, der von Hand geführt wird. Der Gurthobel liegt damit mit seiner ebenen Auflagefläche auf dem Fördergurt auf, wobei das schrägstehende, unten über die Auflagefläche überstehende Messer Deckschichtstreifen wegschneidet, so dass wellenförmige Vertiefungen im Fördergurt entstehen. Durch mehrmaliges Ziehen des Gurthobels über die gesamte Breite des Fördergurtes lassen sich eine Vielzahl von Rillen in den Fördergurt einbringen, womit die Deckschicht oder ein Teil der Deckschicht vom Ende des Fördergurtes entfernt ist. Der Gebrauch des Gurthobels erfordert ein hohes Maß an Geschicklichkeit und Körperkraft, ohne dass sichergestellt ist, dass die frei gehobelte Oberfläche absolut eben und die Restwandstärke des Gurtes an allen Stellen absolut gleichmäßig ist.Such manually movable Gurthobel are basically known and serve to the cover layer or remove parts of the cover layer at the end of a conveyor belt. It is here common to secure the strap end on a support against slipping and then the processing with the planer, whereby the planer is pulled by hand. In general The structure of the Gurthobels resembles a joiner's plane, which is led by hand. The Gurthobel lies with its flat support surface on the conveyor belt, wherein the inclined, Down over the support surface protruding knife cut away cover sheet strips, leaving wavy Recesses in the conveyor belt arise. By repeatedly pulling the Gurthobels over the entire width of the conveyor belt can bring a plurality of grooves in the conveyor belt, whereby the cover layer or a part of the cover layer is removed from the end of the conveyor belt.

Aus der EP 0773 089 A1 ist ein für drückenden Betrieb geeigneter manuell bewegbarer Gurthobel bekannt. Dessen Grundkörper wird allerdings zum Entfernen der Deckschicht oder des Teils der Deckschicht von dem Fördergurt nicht über den Fördergurt bewegt, sondern entlang dessen Stirnfläche. Seitlich auskrakend ist im Grundkörper ein Messer in Art einer dünnen Klinge gehalten, deren freies Ende nach oben abgebogen ist. Im Grundkörper ist zusätzlich ein Niederhalter gelagert, der, der Klinge beim Schneidvorgang vorlaufend, auf der Deckschicht des Fördergurtes aufliegt.From EP 0773 089 A1 is a manually movable Gurthobel suitable for oppressive operation known. However, its body is to remove the cover layer or the part of Cover layer of the conveyor belt is not moved over the conveyor belt, but along the end face. From the side, a knife is held in the base like a thin blade. whose free end is bent upwards. In the main body, a hold-down is additionally stored, the, the blade during the cutting process leading rests on the cover layer of the conveyor belt.

Aus dem DE-GM 8702 754 ist eine Vorrichtung zum Entfernen der Deckschicht oder eines Teiles der Deckschicht von einem Fördergurt bekannt. Es handelt sich um kein Handwerkszeug sondern um eine maschinelle Vorrichtung, mit der die Möglichkeit besteht Längsnuten in ein bereits vulkanisiertes Förderband einzubringen. Hierbei ist sicherzustellen, dass eine genau festgelegte Tiefe, Breite und Profil der Nut in der Banddeckschicht erzeugt wird. Um einen unbegrenzt langen Bandstreifen bearbeiten zu können, wird der Fördergurt relativ zur stationären Schneidvorrichtung bewegt. Diese weist eine stationäre Halterung für eine Klinge auf. Die Klinge ist U-förmig gestaltet, wobei die freien Enden der beiden Schenkel der Klinge in der Halterung gelagert sind.From DE-GM 8702 754 is a device for removing the cover layer or a part the cover layer of a conveyor belt known. It is not a tool but tools to a machine device with the possibility of longitudinal grooves in an already vulcanized To bring in conveyor belt. This is to ensure that a well-defined Depth, width and profile of the groove is produced in the band cover layer. To an infinitely long To edit tape strip, the conveyor belt is relative to the stationary cutter emotional. This has a stationary support for a blade. The blade is U-shaped, wherein the free ends of the two legs of the blade are mounted in the holder.

In der US-A-4 315 450 ist gleichfalls eine maschinelle Vorrichtung zum Entfernen der Deckschicht oder eines Teils der Deckschicht von einem Fördergurt beschrieben. Bei dieser findet eine U-förmig gestaltete Klinge Verwendung, wobei die freien Enden der beiden Schenkel der Klinge in einer Halterung eines Messerschlittens befestigt sind. Der Messerschlitten wird mittels einer Seilwinde angetrieben. Hierbei werden hohe Übersetzungen wirksam, so dass es erforderlich ist, eine relativ dicke und robuste Ausbildung der Messerklinge vorzusehen. Der benötigte maschinelle Aufwand ist bei dieser Vorrichtung erheblich.In US-A-4 315 450 there is also a mechanical device for removing the cover layer or part of the cover layer of a conveyor belt described. In this one finds a U-shaped designed blade use, with the free ends of the two legs of the blade in a holder a knife carriage are attached. The knife carriage is driven by a winch. This high translations are effective, so it is necessary, a relatively thick and to provide robust training of the knife blade. The required mechanical effort is included this device considerably.

Es ist Aufgabe der Erfindung einen manuell bewegbaren Gurthobel der eingangs genannten Art dahingehend weiterzubilden, dass mit diesem bei geringem Kraftaufwand relativ großer Anteil der Deckschicht oder eines Teiles der Deckschicht vom Fördergurt entfernt werden kann, wobei gewährleistet ist, dass die Schneidkräfte optimal vom Gurthobel über die Klinge in den Fördergurt eingeleitet werden.It is an object of the invention is a manually movable Gurthobel of the type mentioned to further develop that with this with a small amount of force relatively large proportion of Cover layer or a part of the cover layer can be removed from the conveyor belt, wherein ensured is that the cutting forces optimally from the Gurthobel over the blade into the conveyor belt be initiated.

Gelöst wird die Aufgabe bei einem manuell bewegbaren Gurthobel der eingangs genannten Art dadurch, dass das Messer als dünne Klinge mit gebogener Schneidkante ausgebildet ist, wobei die Klinge einen zentralen Bereich, dessen Schneidkantenabschnitt parallel zur Auflagefläche des Grundkörpers angeordnet und senkrecht zur Bewegungsrichtung des Gurthobels orientiert ist sowie zwei seitliche Bereiche, deren Schneidkantenabschnitte, ausgehend vom Schneidkantenabschnitt des zentralen Bereiches, in die Öffnung des Grundkörpers hinein abgewinkelt sind, aufweist, wobei die Klinge in ihrem zentralen Bereich zwischen dem Grundkörper und einer Klemmplatte gehalten ist.The problem is solved with a manually movable Gurthobel of the type mentioned in that the knife is designed as a thin blade with a curved cutting edge, wherein the Blade a central area, the cutting edge portion parallel to the bearing surface of the Arranged base body and is oriented perpendicular to the direction of movement of the Gurthobels and two lateral portions, the cutting edge portions, starting from the cutting edge portion of the central region, are angled into the opening of the base body, wherein the blade held in its central region between the base body and a clamping plate is.

Wesentlich ist bei dem erfindungsgemäßen Gurthobel dessen grundsätzliche Wirkungsweise dahingehend, dass er mit seinem Grundkörper über die Deckschicht des Fördergurtes bewegt wird, in Kombination mit der konkreten Ausbildung des Messers als dünne Klinge mit beidseitig gebogenen entständigen Schneidkantenabschnitten. - Durch das Bewegen des Gurthobels mit dessen Auflagefläche über den Fördergurt ist sichergestellt, dass die über den Handgriff in den Gurthobel eingeleiteten Kräfte unmittelbar in die Klinge eingeleitet werden, womit keine Kippmomente in den Gurthobel eingeleitet werden, wie sie bei einer Anlage des Gurthobels beim anderen Funktionstyp, bei dem der Grundkörper neben dem Fördergurt geführt wird, zu verzeichnen sind. In Folge dessen benötigt der erfindungsgemäße Gurthobel auch keinen Niederhalter. Aufgrund des Gurthobeltyps, bei dem das geneigt angeordnete Messer eine Öffnung im Grundkörper durchsetzt und der besonderen Ausbildung der Klinge kann mit dem Gurthobel pro Arbeitshub eine Deckschicht mit einem Querschnitt vom Fördergurt entfernt werden, die der Querschnittsfläche der Klinge, begrenzt durch die Auflagefläche des Grundkörpers entspricht.It is essential in the Gurthobel invention whose fundamental effect to that effect, that he is moved with his body over the top layer of the conveyor belt, in Combination with the concrete training of the knife as a thin blade with bent on both sides make up cutting edge sections. - By moving the Gurthobels with its support surface over the conveyor belt is ensured that the introduced over the handle in the Gurthobel Forces are introduced directly into the blade, so no tilting moments in the Gurthobel be introduced, as in a system of Gurthobels the other type of function, in the basic body is guided next to the conveyor belt, are recorded. Consequently The Gurthobel invention also requires no hold-down. Due to the Gurthobeltyps, in which the inclined arranged knife passes through an opening in the body and the particular Formation of the blade can with the Gurthobel per working stroke a cover layer with a Cross-section to be removed from the conveyor belt, which limits the cross-sectional area of the blade the bearing surface of the body corresponds.

Es wird als besonders vorteilhaft angesehen, wenn der Gurthobel drückend über den Fördergurt bewegt wird. Unter diesem Aspekt sollte die Klinge in ihrem zentralen Bereich unter einem Winkel zur Auflagefläche des Grundkörpers angeordnet sein, der im wesentlichen dem Winkel entspricht, unter dem die Druckkraft zum Betätigen des Gurthobels in den Handgriff eingeleitet wird. Zweckmäßig beträgt dieser Winkel 5° bis 15°, vorzugsweise 7,5° bis 12,5°, insbesondere 10°.It is considered particularly advantageous if the Gurthobel pushing over the conveyor belt is moved. In this aspect, the blade should be in its central area under one Be arranged angle to the bearing surface of the body, which corresponds substantially to the angle, under which the pressure force for actuating the Gurthobels is introduced into the handle. Suitably, this angle is 5 ° to 15 °, preferably 7.5 ° to 12.5 °, in particular 10 °.

Gemäß einer besonderen Ausführungsform der Erfindung ist vorgesehen, dass die Klinge symmetrisch ausgebildet ist. Unabhängig hiervon sollte der Schneidkantenabschnitt des jeweiligen seitlichen Bereiches der Klinge unter einem Winkel von 90° bis 120°, vorzugsweise 100° bis 110°, zum Schneidkantenabschnitt des zentralen Bereiches der Klinge angeordnet sein.According to a particular embodiment of the invention it is provided that the blade is symmetrical is trained. Regardless thereof, the cutting edge portion of the respective lateral should Area of the blade at an angle of 90 ° to 120 °, preferably 100 ° to 110 °, for Cutting edge portion of the central portion of the blade can be arranged.

Besonders gute Schneidergebnisse lassen sich erzielen, wenn die Klinge selbst, ausgehend von der Schneidkante, konisch erweitert ausgebildet ist. Hierbei beträgt der Winkel zwischen den sich an die Schneidkante anschließenden Schneidflanken der Klinge zweckmäßig 15° bis 25°, vorzugsweise 17,5° bis 22,5°, insbesondere 20°. Die dem Grundkörper abgewandte Schneidflanke der Klinge ist insbesondere parallel zur Auflagefläche des Grundkörpers orientiert.Particularly good cutting results can be achieved if the blade itself, starting from the Cutting edge, conically widened is formed. Here is the angle between the on the cutting edge adjoining cutting edges of the blade expedient 15 ° to 25 °, preferably 17.5 ° to 22.5 °, in particular 20 °. The base body facing away from the cutting edge of the blade is oriented in particular parallel to the bearing surface of the body.

Soll die Deckschicht oder der Teil der Deckschicht im Abstand von der Stirnfläche des Fördergurtes von diesem entfernt werden, wird es als vorteilhaft angesehen, wenn der Gurthobel zusätzlich mit einer Führungseinrichtung verbunden ist, die der seitlichen Anlage an der Stirnseite des Fördergurtes dient. Die Führungseinrichtung ist vorzugsweise als Leiste ausgebildet, die mit dem Grundkörper verbunden ist. Sie sollte relativ zum Grundkörper verstellbar sein.If the cover layer or the part of the cover layer at a distance from the end face of the conveyor belt be removed from this, it is considered advantageous if the Gurthobel in addition to a guide device is connected, the lateral contact with the front side of the conveyor belt serves. The guide device is preferably designed as a bar, which is connected to the main body connected is. It should be adjustable relative to the base body.
