Aus dem Dokument
Bei der bekannten Vorrichtung werden die Bearbeitungselemente jeweils mittels einer Befestigungsschraube mit dem Keilriemen der Fördereinrichtung verschraubt.

Somit ist ein Wechsel der Bearbeitungselemente relativ umständlich.In the known device, the processing elements are each screwed by means of a fastening screw with the V-belt of the conveyor. This has the disadvantage that the screw can be solved only with the help of a tool. Thus, a change of the processing elements is relatively cumbersome.
Ausgehend von dem bekannten Stand der Technik ist es Aufgabe der Erfindung, eine Vorrichtung und ein Bearbeitungselement zum Bearbeiten eines Werkstücks anzugeben, die bzw. das ein einfaches und schnelles Wechseln des Bearbeitungselements und gleichzeitig eine verdrehsichere Befestigung des Bearbeitungselements an dem Riemen ermöglicht.Starting from the known prior art, it is an object of the invention to provide a device and a processing element for machining a workpiece, which allows a simple and quick change of the processing element and at the same time a rotationally secure attachment of the processing element to the belt.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 und ein Bearbeitungselement mit den Merkmalen des Anspruchs 15 gelöst. Vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen angegeben.This object is achieved by a device having the features of claim 1 and a processing element having the features of claim 15. Advantageous developments are specified in the dependent claims.
Durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 wird ein einfaches und schnelles Wechseln der Bearbeitungselemente und gleichzeitig eine verdrehsichere Befestigung der Bearbeitungselemente an dem Riemen erreicht, da insbesondere die Bearbeitungselemente jeweils einen Grundkörper und ein mit dem Grundkörper verbundenes erstes Verbindungselement umfassen, das mit einem zum ersten Verbindungselement komplementären und mit dem Riemen verbundenen zweiten Verbindungselement verbindbar ist. Das erste Verbindungselement umfasst einen Drehkörper, und das zweite Verbindungselement hat einen Verbindungsbereich zum Verbinden mit dem Drehkörper. Dabei erfolgt bei einer Drehung des Drehkörpers in eine erste Drehrichtung eine Verbindung des Drehkörpers mit dem Verbindungsbereich. Ferner erfolgt bei einer Drehung des Drehkörpers in eine der ersten Drehrichtung entgegengesetzten zweiten Drehrichtung eine Trennung des Drehkörpers von dem Verbindungsbereich. Der Drehkörper ist relativ zu dem Grundkörper derart angeordnet und mit diesem verbunden, dass bei der Bearbeitung des Werkstücks über den Grundkörper eine resultierende Kraft auf den Drehkörper ausgeübt wird, die ein Drehmoment für eine Drehung des Drehkörpers in die erste Drehrichtung bewirkt. Somit können die Bearbeitungselemente einfach und schnell gewechselt und gleichzeitig verdrehsicher an dem Riemen befestigt werden. Durch das Drehmoment wird verhindert, dass der Drehkörper seinen verbundenen Zustand während der Bearbeitung des Werkstücks verlässt.By a device having the features of claim 1, a simple and quick change of the processing elements and at the same time a rotationally secure attachment of the processing elements is achieved on the belt, since in particular the processing elements each comprise a base body and a connected to the main body first connecting element, which with a to first connecting element complementary and connected to the belt second connecting element is connectable. The first connection member includes a rotary body, and the second connection member has a connection portion for connecting to the rotary body. In this case, upon rotation of the rotary body in a first direction of rotation, a connection of the rotary body to the connecting area takes place. Furthermore, upon rotation of the rotary body in a direction of rotation opposite to the second rotational direction, separation of the rotary body from the connecting area takes place. The rotary body is arranged relative to the base body and connected thereto, that during the processing of the workpiece on the base body, a resultant force is exerted on the rotary body, which causes a torque for rotation of the rotary body in the first rotational direction. Thus, the processing elements can be changed quickly and easily and simultaneously secured against rotation on the belt. The torque prevents the rotary body from leaving its connected state during machining of the workpiece.
Vorzugsweise bleibt das Drehmoment während der Bearbeitung des Werkstücks im Wesentlichen gleich. Somit kann der verbundene Zustand des Drehkörpers während des Bearbeitungsprozesses sicher beibehalten werden.Preferably, the torque during machining of the workpiece remains substantially the same. Thus, the connected state of the rotary body can be securely maintained during the machining process.
Vorzugsweise erfolgt die Drehung des Drehkörpers in die erste Drehrichtung bzw. in die zweite Drehrichtung jeweils um eine Drehachse, wobei die Drehachse senkrecht zur Oberfläche des Riemens ist. Somit kann der Drehkörper parallel zur Oberfläche des Riemens gedreht werden, um den Drehkörper mit dem Verbindungsbereich zu verbinden bzw. diesen von dem Verbindungsbereich zu trennen.Preferably, the rotation of the rotary body takes place in the first rotational direction and in the second rotational direction in each case about an axis of rotation, wherein the axis of rotation is perpendicular to the surface of the belt. Thus, the rotary body can be rotated in parallel with the surface of the belt to connect the rotary body to the connecting portion and to separate it from the connecting portion.
Vorzugsweise sind der Drehkörper und der Grundkörper zusammen einstückig ausgebildet. Somit kann ein unerwünschtes Verdrehen des Grundkörpers relativ zu dem Drehkörper während des Bearbeitungsprozesses vermieden werden.Preferably, the rotary body and the base body are integrally formed together. Thus, an undesirable rotation of the body relative to the rotary body during the machining process can be avoided.
Vorzugsweise ist der Drehkörper relativ zu einer Längsseite des Grundkörpers und/oder relativ zu einer Querseite des Grundkörpers asymmetrisch an einer dem zweiten Verbindungselement zugewandten Unterseite des Grundkörpers angeordnet. Somit führen die während des Bearbeitungsprozesses, insbesondere eines Schleifprozesses, an der Oberfläche des Grundkörpers angreifenden Kräfte zu der das Drehmoment bewirkenden, resultierenden Kraft auf den Drehkörper.The rotary body is preferably arranged asymmetrically relative to a longitudinal side of the base body and / or relative to a transverse side of the base body on an underside of the base body facing the second connecting element. Thus, during the machining process, in particular a grinding process, forces acting on the surface of the base body lead to the resultant force on the rotary body that effects the torque.
Vorzugsweise ist ein erster Abstand des Drehkörpers von einer in Schleifrichtung vorderen Kante des Grundkörpers kleiner als ein zweiter Abstand des Drehkörpers von einer in Schleifrichtung hinteren Kante des Grundkörpers. Ferner kann ein dritter Abstand des Drehkörpers von einer in Vorschubrichtung vorderen Kante des Grundkörpers kleiner als ein vierter Abstand von einer in Vorschubrichtung hinteren Kante des Grundkörpers sein. Somit kann der Drehkörper in einem in Schleifrichtung und in Vorschubrichtung vorderen Bereich des Grundkörpers vorgesehen sein.Preferably, a first distance of the rotary body from a front edge in the direction of the main body is smaller than a second distance of the rotary body from a rear edge in the direction of the main body. Furthermore, a third distance of the rotary body from a front edge of the main body in the feed direction may be smaller than a fourth distance from a rear edge of the main body in the feed direction. Thus, the rotary body may be provided in a front in the grinding direction and in the feed direction of the body.
Vorzugsweise liegt der erste Abstand zwischen 35 und 45 mm. Ferner liegt der zweite Abstand zwischen 20 und 30 mm. Somit kann ein geeigneter Wert für die resultierende Kraft auf den Drehkörper vorgegeben werden.Preferably, the first distance is between 35 and 45 mm. Furthermore, the second distance is between 20 and 30 mm. Thus, a suitable value for the resulting force can be given to the rotating body.
Vorzugsweise ist der Verbindungsbereich durch eine Ausnehmung in dem zweiten Verbindungselement gebildet. Somit kann der Verbindungsbereich relativ einfach hergestellt werden.Preferably, the connection area is formed by a recess in the second connection element. Thus, the connection area can be made relatively easily.
Vorzugsweise ist die Seitenwand der Ausnehmung in Richtung des Inneren der Ausnehmung geneigt. Somit kann der Drehkörper von der Ausnehmung sicher aufgenommen werden.Preferably, the side wall of the recess is inclined in the direction of the interior of the recess. Thus, the rotary body can be securely received by the recess.
Vorzugsweise umfasst die Vorrichtung eine Transporteinrichtung zum Erzeugen einer Relativbewegung zwischen dem zu bearbeitenden Werkstück und den Bearbeitungselementen. Somit kann das Werkstück zur Bearbeitung mittels der Bearbeitungselemente in eine Vorschubrichtung bewegt werden.Preferably, the device comprises a transport device for generating a relative movement between the workpiece to be machined and the processing elements. Thus, the workpiece can be moved for processing by means of the processing elements in a feed direction.
Vorzugsweise ist der Riemen derart ausgebildet, dass die Bearbeitungselemente im Bereich des zu bearbeitenden Werkstücks in eine erste translatorische Bewegungsrichtung bewegt werden. Ferner ist die Transporteinrichtung derart ausgebildet, dass das Werkstück in eine zweite translatorische Bewegungsrichtung bewegt wird. Dabei ist ein Winkel zwischen der ersten translatorischen Bewegungsrichtung und der zweiten translatorischen Bewegungsrichtung von 0° oder 180° verschieden. Somit können die erste und zweite translatorische Bewegungsrichtung relativ zueinander jede Ausrichtung außer einer parallelen oder antiparallelen Ausrichtung haben.Preferably, the belt is designed such that the processing elements are moved in the region of the workpiece to be machined in a first translational movement direction. Furthermore, the transport device is designed such that the workpiece is moved in a second translational movement direction. In this case, an angle between the first translational movement direction and the second translational movement direction is different from 0 ° or 180 °. Thus, the first and second translational directions of movement relative to each other may have any alignment other than parallel or anti-parallel alignment.
Vorzugsweise beträgt der Winkel zwischen der ersten translatorischen Bewegungsrichtung und der zweiten translatorischen Bewegungsrichtung 90°. Somit können die erste und zweite translatorische Bewegungsrichtung senkrecht zueinander ausgerichtet sein. Insbesondere entspricht die erste translatorische Bewegungsrichtung der Schleifrichtung, während die zweite translatorische Bewegungsrichtung der Vorschubrichtung entspricht.Preferably, the angle between the first translational movement direction and the second translational movement direction is 90 °. Thus, the first and second translational movement direction to be aligned perpendicular to each other. In particular, the first translational movement direction corresponds to the grinding direction, while the second translational movement direction corresponds to the feed direction.
Vorzugsweise sind das zweite Verbindungselement und der Riemen mittels einer Schraube im mittleren Bereich des Riemens verbunden. Somit kann das zweite Verbindungselement zuverlässig an dem Riemen angebracht werden.Preferably, the second connecting element and the belt are connected by means of a screw in the middle region of the belt. Thus, the second connection member can be reliably attached to the belt.
Vorzugsweise ist das zweite Verbindungselement mittels zweier Stifte verdrehsicher gegenüber dem Riemen gehalten. Vorzugsweise sind die Schraube und die zwei Stifte in einer Linie senkrecht zur Schleifrichtung angeordnet. Ferner sind die zwei Stifte im Randbereich des Riemens auf zwei gegenüberliegenden Seiten des Verbindungsbereichs angeordnet. Somit kann ein Verdrehen des zweiten Verbindungselements relativ zum Riemen während des Bearbeitungsprozesses vermieden werden.Preferably, the second connecting element is held against rotation by means of two pins against the belt. Preferably, the screw and the two pins are arranged in a line perpendicular to the grinding direction. Furthermore, the two pins are arranged in the edge region of the belt on two opposite sides of the connection region. Thus, twisting of the second connecting element relative to the belt during the machining process can be avoided.
Vorzugsweise sind die Bearbeitungselemente derart beabstandet voneinander angeordnet, dass der Grundkörper bei der Drehung des Drehkörpers in die erste Drehrichtung bzw. in die zweite Drehrichtung um einen Drehwinkel insbesondere innerhalb eines Drehwinkelbereichs von 25° bis 120°, beispielsweise innerhalb eines Drehwinkelbereichs von 35° bis 95°, frei drehbar ist. Somit kann ein ausreichender Abstand zwischen den Bearbeitungselementen bereitgestellt werden, so dass diese jeweils einzeln gewechselt werden können.Preferably, the processing elements are arranged spaced apart from one another such that the base body in the rotation of the rotary body in the first direction of rotation or in the second rotational direction by a rotation angle, in particular within a rotation angle range of 25 ° to 120 °, for example within a rotation angle range of 35 ° to 95 °, is freely rotatable. Thus, a sufficient distance between the processing elements can be provided so that they can be changed individually.
Vorzugsweise befindet sich der Grundkörper nach der Verbindung des Drehkörpers mit dem Verbindungsbereich in einem eingebauten Zustand. Ferner befindet sich der Grundkörper nach der Trennung des Drehkörpers von dem Verbindungsbereich in einem ausgebauten Zustand. Dabei sind das erste Verbindungselement und das zweite Verbindungselement schraubenlos verbindbar und derart ausgebildet, dass ein Wechsel zwischen dem eingebauten Zustand und dem ausgebauten Zustand des Grundkörpers manuell erfolgt. Somit kann ein Schneilwechselsystem für die einzelnen Bearbeitungselemente realisiert werden.Preferably, the base body is in an installed state after the connection of the rotary body with the connection region. Further, after the separation of the rotary body from the connecting portion, the main body is in a disassembled state. In this case, the first connecting element and the second connecting element screwless connectable and designed such that a change between the installed state and the disassembled state of the body is done manually. Thus, a snow change system for the individual processing elements can be realized.
Vorzugsweise ist der Riemen ein Keilriemen, der über zwei Riemenscheiben umgelenkt und endlos geführt wird. Somit kann ein sicheres Führen der auf dem Riemen angeordneten Bearbeitungselemente erreicht werden.Preferably, the belt is a V-belt, which is deflected over two pulleys and guided endlessly. Thus, a safe guiding of the arranged on the belt processing elements can be achieved.
Vorzugsweise umfassen die Bearbeitungselemente jeweils ein Schleifwerkzeug, ein Bürstenwerkzeug oder ein Polierwerkzeug zum Schleifen, Bürsten bzw. Polieren der Oberfläche des Werkstücks. Somit können die Bearbeitungselemente insbesondere für den Schleifprozess vorgesehen sein.Preferably, the processing elements each comprise a grinding tool, a brush tool or a polishing tool for grinding, brushing or polishing the surface of the workpiece. Thus, the processing elements may be provided in particular for the grinding process.
Gemäß einem weiteren Aspekt der Erfindung ist ein Bearbeitungselement für den Einsatz in einer der im Vorhergehenden beschriebenen Vorrichtung vorgesehen. Das Bearbeitungselement umfasst einen Grundkörper und ein mit dem Grundkörper verbundenes erstes Verbindungselement, das mit einem zum ersten Verbindungselement komplementären zweiten Verbindungselement der Vorrichtung verbindbar ist. Das erste Verbindungselement umfasst einen Drehkörper, der mit einem Verbindungsbereich des zweiten Verbindungselements der Vorrichtung verbindbar ist. Bei einer Drehung des Drehkörpers in eine erste Drehrichtung erfolgt eine Verbindung des Drehkörpers mit dem Verbindungsbereich. Bei einer Drehung des Drehkörpers in eine der ersten Drehrichtung entgegengesetzten zweiten Drehrichtung erfolgt eine Trennung des Drehkörpers von dem Verbindungsbereich. Der Drehkörper ist relativ zu dem Grundkörper derart angeordnet und mit diesem verbunden, dass bei einer vorbestimmten Relativbewegung zur Bearbeitung eines Werkstücks über den Grundkörper eine resultierende Kraft auf den Drehkörper ausgeübt wird, die ein Drehmoment für eine Drehung des Drehkörpers in die erste Drehrichtung bewirkt.According to a further aspect of the invention, a machining element is provided for use in one of the devices described above.
