Definitions
- the invention relates to a belt finishing device, comprising a guide device for guiding the finishing belt, a rotary drive for the rotary drive of a workpiece to be finished to be machined around its workpiece axis and an oscillation drive by means of which the finishing belt and the workpiece can be driven to oscillate relative to one another in a direction parallel to the workpiece axis , wherein a finishing belt supply is provided for the finishing belt, from which the finishing belt can be fed to a work area and from there to a collecting area.
- the finishing processing of a workpiece is a process for surface processing of a workpiece, also known as "superfinishing” or “superfinishing process”.
- an abrasive finishing tool in the form of a finishing stone or a finishing tape
- the workpiece surface to be machined rotates.
- the rotation of the workpiece surface to be machined is superimposed on an oscillating movement in which the finishing tool and the workpiece surface to be machined move relative to one another in directions parallel to the axis of rotation.
- a tape finishing device is, for example, from US Pat DE 10 2014 213 194 A1 known.
- To handle the finishing tape supply rolls are used, from which fresh finishing tape is unwound and fed to the work area.
- the active surface wears out, so that fresh finishing belt sections are supplied from the supply at predefinable intervals.
- Worn / used finishing tape sections are fed from the work area to a collecting area and there wound onto a collecting roll to be disposed of later.
- the present invention is based on the object of simplifying the handling of the finishing belt.
- a separating device is provided in the collecting area, which separates finishing belt sections with a motor-driven separating element.
- separating the finishing tape sections they can be collected more easily and disposed of more easily compared to winding a complete finish tape onto a collecting roll.
- the motor-driven separating element makes it possible to control the separating device as required without manual intervention being necessary.
- the separating device according to the invention is arranged in the collecting area of the tape finishing device, it is possible to operate the separating device without interrupting the production operation of the tape finishing device, that is to say the finishing machining of a workpiece surface. It is possible to use the cutting device comparatively frequently, so that comparatively short finishing tape sections can be cut off, for example finishing tape sections whose maximum length is only 100 mm. These short finishing tape sections can be collected and disposed of in a simple manner, regardless of the state of consumption of the supply roll for fresh finishing tape.
- the separating device has two separating elements in the form of separating disks, which interact in a separating area.
- Such a separating device enables a particularly reliable separation of finishing tape sections in a locally limited and thus clearly defined separating area.
- the cutting disks comprise a grooving knife disk and a circular knife disk. These disks rotate in opposite directions of rotation and are in engagement with one another in such a way that the circular cutting edge engages the groove area of a grooving knife disk with a circumferential cutting edge. In this area of engagement, the two disks are in contact with one another so that the finishing tape to be cut can neither escape nor be crushed.
- the cutting disks are each coupled in terms of movement to a frictional engagement element, and if the frictional engagement elements are in frictional engagement with one another in order to transmit a rotational movement of the cutting disks. In this way, the rotary movement can be transmitted from one cutting wheel to the other cutting wheel. As a result of the contact between the frictional engagement elements, the frictional engagement elements move at the same speed in the area of the frictional engagement. It is therefore preferred if the frictional engagement elements are disk-shaped and have cylindrical frictional engagement surfaces, their distance from the respective axis of rotation is identical relative to each other. In this way it is possible to drive the cutting disks in a simple manner at the same speed of rotation.
- cylindrical frictional engagement surfaces have a radius which at least substantially corresponds to the radius of the cutting disks. This enables a comparatively simple construction of the separating device. In addition, there are further advantages in connection with the embodiments of the invention described below.
- the frictional engagement elements are arranged adjacent to the separating area, viewed in the direction of the finish belt. In this way, the torque is transmitted immediately adjacent to the separation area.
- the frictional engagement elements have frictional engagement surfaces which act as clamping surfaces for the finishing belt.
- the frictional engagement surfaces fulfill a further function, namely the fixing of a finishing tape to be severed between the frictional engagement surfaces.
- the cutting speed across the width of the finishing belt corresponds at least approximately to the feed speed of the finishing belt viewed in the width direction of the finishing belt.
- the finishing belt is clamped and fixed in such a way that the finishing belt is not exposed to any further driving forces during the cutting process, i.e. is neither attracted too quickly with respect to the cutting device nor pushed off in the opposite direction.
- a collecting container for collecting separated finishing belt sections is advantageously arranged in the collecting area.
- Such a collecting container does not necessarily have to be able to accommodate finishing tape sections of a complete supply roll. It can also be a small, light and therefore easier to handle collecting container.
- the collecting container can be, for example, a collecting channel.
- the collecting container can be arranged in a stationary manner on the tape finishing device, so that it cannot be moved with respect to a machine frame of the tape finishing device.
- the collecting container is arranged movably within the collecting area, for example along a movement axis running parallel to a workpiece axis.
- finishing tape For a simple construction of the tape finishing device, it is preferred if the finishing tape to be cut runs in a vertical direction in the collecting area. Such a finishing tape can be severed particularly easily, in particular when the severing device according to the invention is effective in a horizontal severing plane.
- the cutting device is arranged in a stationary manner in relation to a machine frame of the tape finishing device.
- a feed speed of the finishing belt in a direction parallel to the workpiece axis is at least approximately equal to a cutting speed of the cutting device across the width of the finishing belt. In this way, the finishing belt is not exposed to any further driving forces during the severing process, that is to say it is neither attracted too quickly in relation to the severing device nor repelled in the opposite direction.
- a feed device is provided, by means of which the separating device can be moved in a direction parallel to the workpiece axis.
- the cutting device (possibly with a collecting container connected to it) can be moved parallel to the workpiece axis so that a finishing belt can be cut completely independently of the advance and the position of a guide device for guiding the finishing belt in the work area.
- a feed speed of the feed device is at least approximately equal to a cutting speed of the cutting device across the width of the finishing belt.
- the finishing belt is not exposed to any further driving forces during the severing process, that is to say it is neither attracted too quickly in relation to the severing device nor repelled in the opposite direction.
- the feed device may comprise a stationary drive device, that is to say for example a motor which is stationary in relation to the machine frame of the tape finishing device.
- the drive movement of such a motor can be transmitted to the separating device via gear parts (e.g. a drive belt).
- the feed device is preferably a linear drive, for example an electric linear motor, the rotor of which is connected to the separating device.
- the linear drive is, in particular, a pneumatic cylinder without a piston rod.
- a drive device which can be moved together with the separating device, for example a rotary drive which is arranged on the separating device and which drives a gearwheel.
- the toothed wheel meshes with a toothed rack which extends parallel to the axis of movement of the, so that the rotary movement of the toothed wheel is converted into a feed movement of the separating device along the axis of movement becomes.
- a gear device for converting a feed movement of the separating device into a drive movement of the separating element.

- the workpiece surface to be finished can be, for example, the circumferential surface of a crank pin 22.
- the belt finishing device 10 For the finishing machining of a workpiece surface, the belt finishing device 10 comprises a finishing belt 24, which is supplied from a finishing belt supply 26, for example a supply roll.
- a guide device 28 is provided for guiding the finishing belt 24. This includes, in a manner known per se, pressing elements which press the finishing belt 24 in a work area 30 against the workpiece surface to be finished.

- the finishing belt 24 can be advanced transversely to its direction (i.e. in the width direction of the finishing belt) in the area of the separating device 34 by moving the guide devices 28 parallel to the workpiece axis 20, for example by means of a slide 36.
- a tape finishing device 10 usually has a plurality of guide devices 28 which are arranged parallel to one another so that, viewed along the workpiece axis 20, several finishing tapes 24 can be brought into engagement with different workpiece surfaces of a workpiece 18 at the same time.
- the separating device 34 is guided and movable along a guide device 38 along a movement axis 40.
- the movement axis 40 extends parallel to the workpiece axis 20.
- the guide device 38 has a rail-shaped base body 42.
- the base body 42 serves to arrange a feed device 44 in the form of a linear drive 46.
- the linear drive 46 serves to drive a rotor 48, which carries the separating device 34, along the movement axis 40.
- the separating device 34 has two separating elements 50 and 52, which are designed in the form of two separating disks 54 and 56.
- the cutting disks 54 and 56 interact with respective cutting edges in a cutting area 58.
- One of the cutting edges is formed in that the cutting disk 54 is designed as a circular knife disk.
- the other cutting edge is formed in that the cutting disk 56 is designed as a grooving knife disk.
- the cutting disks 50 and 52 rotate about mutually parallel axes of rotation 64 and 66, which are oriented parallel to a direction 68 of the finishing belt 24 in the collecting area 32.
- a compression spring 70 is provided to generate a pressing force in a direction parallel to the direction 68. These presses the cutting edge of the cutting disk 54 against the cutting edge of the cutting disk 56.
- Bearing bodies 72, 74 are provided for the rotary mounting of the cutting disks 54, 56 about the axes of rotation 64, 66. These are each connected to carriages 76, 78, which can be moved relative to carriage carriers 80, 82 along carriage axes 84, 86.
- the slide axes 84, 86 are aligned parallel to one another; in particular, the axes 84 and 86 are aligned with one another.
- the axes 84 and 86 are oriented perpendicular to the axes of rotation 64 and 66 and perpendicular to the workpiece axis 20.
- the carriages 76, 78 are acted upon by force parallel to the carriage axes 84, 86 by means of tension springs 88 in the direction towards one another.
- a corresponding counterforce is generated in an area 90 in which two frictional engagement elements 91 and 92 abut one another in a frictionally engaged manner.
- the frictional engagement elements 91 and 92 are each coupled to one of the separating disks 54, 56 in a rotationally fixed manner.
- the frictional engagement elements 91, 92 have cylindrical frictional engagement surfaces 94, 96 which are in frictional contact with one another in the region 90.
- the frictional engagement surfaces 94, 96 are made, for example, from a plastic, in particular from Vulkollan®.
- the region 90 is arranged directly adjacent to the separating region 58, as seen along the direction 68 of the finishing belt 24.

- the gear mechanism 98 comprises a toothed rack 100 fixedly connected to the base body 42 and extending along the rail.
- the toothed rack 100 interacts with a toothed wheel 102, which is rotatably mounted on the separating device 34 about an axis of rotation 104.
- a rotary movement of the gear wheel 102 is transmitted by meshing engagement to a further gear wheel 106, which is connected in a rotationally fixed manner to the frictional engagement element 92 and the separating disk 56.
- a movement of the separating device 34 along the movement axis 40 by means of the feed device 44 results in the gear wheel 102 rolling on the rack 100.
- the resulting rotational movement of the gear wheel 102 is transmitted in the opposite direction of rotation to the gear wheel 106, which thus rotates about the axis of rotation 66, specifically together with the frictional engagement element 92 and the cutting disk 56.
- a feed direction 108 of the feed device 44 is shown, which is translated into a rotary movement 110 of the gear wheel 102.
- the gearwheel 106 rotates in opposite directions about the axis 66; the cutting disk 54 rotates in the same direction around the axis 64 in relation to the direction of rotation 110.
- the finishing belt 24 arrives in the engagement area 90 between the frictional engagement surfaces 91 and 92 and is drawn into the engagement region 90 from the point of view of the finish belt 24, so that the friction engagement surfaces 94, 96 as Clamping surfaces for the finishing belt 24 are effective.
- the finishing tape 24 to be severed is fixed in the area 90 and can be severed in the severing area 58 immediately adjacent thereto. Since the cutting edges of the cutting disks 54, 56 have essentially the same diameter as the cylindrical frictional engagement surfaces 94, 96, the cutting speed across the width of the finishing belt 24 is at least approximately the same as the circumferential speed of the frictional engagement surfaces 94, 96 in the area 90. In this way the finishing belt 24 can be severed largely free of transverse forces.
- Sections cut off from the finishing belt 24 can be collected in a collecting container 112.
- the collecting container 112 is, for example, a collecting channel 114 which can be moved together with the separating device 34 along the movement axis 40. Finishing strip sections collected in the collecting chute 114 can be disposed of from there or else only temporarily stored in the collecting chute 114 and fed from there to a stationary additional collecting container 116. For the transfer of finishing tape sections from the collecting channel 114 into the additional collecting container 116, slides or fans can be used, for example. It is also conceivable that the collecting channel 114 extends along the entire length of the rail 42.
- the collecting chute 114 can be disposed of by means of a conveyor belt. Such a conveyor belt preferably extends along a floor of the collecting chute 114.
- Manual disposal of the collecting channel 114 is also possible.
- This separating device 34 is a stationary separating device, which is therefore not movable along a movement axis 40 parallel to the workpiece axis 20 in a feed direction.
- the separating device 34 according to Figures 5 to 7 has a drive motor 118 which drives a cutting disk 56 about an axis of rotation 66 in the direction of rotation.
- the rotary movement is transmitted to a further cutting disk 54 about an axis 64 by means of frictional engagement elements 91 and 92, as described above with reference to FIG Figures 2 to 4 described.
- the axes 64 and 66 are each arranged on carriers 120, 122 extending approximately parallel to the workpiece axis 20.
- the supports 120, 122 are acted upon by tension springs 88 in mutually facing directions.
- the corresponding counterforce arises in the engagement area 90 through pressure contact between the frictional engagement elements 90 and 92.
- a spacer device 124 is provided. This has a spindle axis 126, which is supported on the carrier 120 and is effective against the carrier 122, so that the carriers 120 and 122 can be pressed apart against the force of the tension springs 88.
- One of the carriers is preferably stationary, for example the carrier 120, while the other carrier is movable, for example the carrier 122.
- the separating device 34 comprises according to FIG Figures 5 to 7 Guide elements 126, 128, which are effective in a guide plane which is oriented perpendicular to the direction in which the finishing belt 24 extends.
- the guide elements 126, 128 define a V-shaped tapering guide space (cf. Figure 6 ).

Description
Die Erfindung betrifft eine Bandfinishvorrichtung, umfassend eine Führungseinrichtung zur Führung von Finishband, einen Rotationsantrieb zum rotatorischen Antrieb eines finishend zu bearbeitenden Werkstücks um dessen Werkstückachse und einen Oszillationsantrieb, mittels welchem das Finishband und das Werkstück in einer zu der Werkstückachse parallelen Richtung relativ zueinander oszillierend antreibbar sind, wobei für das Finishband ein Finishbandvorrat vorgesehen ist, aus welchem heraus das Finishband einem Arbeitsbereich und von dort aus einem Sammelbereich zuführbar ist.The invention relates to a belt finishing device, comprising a guide device for guiding the finishing belt, a rotary drive for the rotary drive of a workpiece to be finished to be machined around its workpiece axis and an oscillation drive by means of which the finishing belt and the workpiece can be driven to oscillate relative to one another in a direction parallel to the workpiece axis , wherein a finishing belt supply is provided for the finishing belt, from which the finishing belt can be fed to a work area and from there to a collecting area.
Die finishende Bearbeitung eines Werkstücks ist ein auch als "Superfinishen" oder "Feinstbearbeitungsverfahren" bezeichnetes Verfahren zur Oberflächenbearbeitung eines Werkstücks. Bei diesem Verfahren wird ein abrasiv wirkendes Finishwerkzeug (in Form eines Finishsteins oder eines Finishbands) auf die zu bearbeitende Werkstückoberfläche gedrückt. Dabei rotiert die zu bearbeitende Werkstückoberfläche. Üblicherweise wird der Rotation der zu bearbeitenden Werkstückoberfläche eine oszillierende Bewegung überlagert, bei welcher sich das Finishwerkzeug und die zu bearbeitende Werkstückoberfläche in zu der Rotationsachse parallelen Richtungen relativ zueinander bewegen.The finishing processing of a workpiece is a process for surface processing of a workpiece, also known as "superfinishing" or "superfinishing process". In this process, an abrasive finishing tool (in the form of a finishing stone or a finishing tape) is pressed onto the workpiece surface to be processed. The workpiece surface to be machined rotates. Usually, the rotation of the workpiece surface to be machined is superimposed on an oscillating movement in which the finishing tool and the workpiece surface to be machined move relative to one another in directions parallel to the axis of rotation.
Eine Bandfinishvorrichtung ist beispielsweise aus der
In der Praxis gibt es eine Entwicklung dahingehend, Vorratsrollen mit Finishbändern bereitzustellen, die eine Länge von bis zu 300 Metern haben können. Das Aufwickeln eines solch langen Finishbands ist fehleranfällig. Ferner können die Sammelrollen in ihrem voll aufgewickelten Zustand ein erhebliches Gewicht aufweisen, was die Handhabung der Sammelrollen im Zuge ihrer Entsorgung erschwert. Bedingt durch die erschwerte Handhabung steigt auch das Risiko, das sich das aufgewickelte Finishband von einer vollen Sammelrolle ablöst. Insgesamt gestaltet sich eine schnelle und einfache Entsorgung des Finishbands als schwierig.In practice, there is a development to provide supply rolls with finishing belts that can have a length of up to 300 meters. Winding up such a long finishing tape is prone to errors. Furthermore, the collecting rolls can have a considerable weight in their fully wound-up state, which makes handling of the collecting rolls difficult in the course of their disposal. Due to the difficult handling, there is also an increased risk that the wound finishing tape will become detached from a full collecting roll. Overall, a quick and easy disposal of the finishing belt turns out to be difficult.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, die Handhabung des Finishbands zu vereinfachen.Proceeding from this, the present invention is based on the object of simplifying the handling of the finishing belt.
Diese Aufgabe wird bei einer Bandfinishvorrichtung der eingangs genannten Art durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.In the case of a tape finishing device of the type mentioned at the outset, this object is achieved by the characterizing features of claim 1.
Erfindungsgemäß ist in dem Sammelbereich eine Trenneinrichtung vorgesehen, die mit einem motorisch angetriebenen Trennelement Finishbandabschnitte abtrennt. Durch die Abtrennung von Finishbandabschnitten können diese im Vergleich zu einer Aufwicklung eines vollständigen Finishbands auf eine Sammelrolle einfacher gesammelt und einfacher entsorgt werden. Das motorisch angetriebene Trennelement ermöglicht es, die Trenneinrichtung bedarfsweise anzusteuern, ohne dass es eines manuellen Eingriffs bedarf.According to the invention, a separating device is provided in the collecting area, which separates finishing belt sections with a motor-driven separating element. By separating the finishing tape sections, they can be collected more easily and disposed of more easily compared to winding a complete finish tape onto a collecting roll. The motor-driven separating element makes it possible to control the separating device as required without manual intervention being necessary.
Da die erfindungsgemäße Trenneinrichtung in dem Sammelbereich der Bandfinishvorrichtung angeordnet ist, ist ein Betrieb der Trenneinrichtung möglich, ohne den produzierenden Betrieb der Bandfinishvorrichtung, also die finishende Bearbeitung einer Werkstückoberfläche, zu unterbrechen. Es ist möglich, die Trenneinrichtung vergleichsweise häufig einzusetzen, sodass vergleichsweise kurze Finishbandabschnitte abgetrennt werden können, beispielsweise Finishbandabschnitte, deren Länge maximal lediglich 100 mm beträgt. Diese kurzen Finishbandabschnitte können aufgefangen und in einfacher Weise entsorgt werden, auch unabhängig von dem Verbrauchszustand der Vorratsrolle für frisches Finishband.Since the separating device according to the invention is arranged in the collecting area of the tape finishing device, it is possible to operate the separating device without interrupting the production operation of the tape finishing device, that is to say the finishing machining of a workpiece surface. It is possible to use the cutting device comparatively frequently, so that comparatively short finishing tape sections can be cut off, for example finishing tape sections whose maximum length is only 100 mm. These short finishing tape sections can be collected and disposed of in a simple manner, regardless of the state of consumption of the supply roll for fresh finishing tape.
Erfindungsgemäß ist vorgesehen, dass die Trenneinrichtung zwei Trennelemente in Form von Trennscheiben aufweist, die in einem Trennbereich zusammenwirken. Eine solche Trenneinrichtung ermöglicht eine besonders zuverlässige Abtrennung von Finishbandabschnitten in einem lokal begrenzten und somit eindeutig definierten Trennbereich.According to the invention it is provided that the separating device has two separating elements in the form of separating disks, which interact in a separating area. Such a separating device enables a particularly reliable separation of finishing tape sections in a locally limited and thus clearly defined separating area.
Eine besonders zuverlässige Abtrennung von Finishbandabschnitten wird ermöglicht, wenn die Trennscheiben eine Nutmesserscheibe und einer Tellermesserscheibe umfassen. Diese Scheiben rotieren in gegenläufigen Rotationsrichtungen und stehen miteinander derart in Eingriff, dass die Tellermesserscheibe mit einer umlaufenden Schneidkante in den Nutbereich einer Nutmesserscheibe eingreift. In diesem Eingriffsbereich liegen die beiden Scheiben aneinander an, sodass das zu durchtrennende Finishband weder ausweichen noch verquetscht werden kann.A particularly reliable separation of finishing tape sections is made possible if the cutting disks comprise a grooving knife disk and a circular knife disk. These disks rotate in opposite directions of rotation and are in engagement with one another in such a way that the circular cutting edge engages the groove area of a grooving knife disk with a circumferential cutting edge. In this area of engagement, the two disks are in contact with one another so that the finishing tape to be cut can neither escape nor be crushed.
Vorteilhaft ist es ferner, wenn die Trennscheiben jeweils mit einem Reibschlusselement bewegungsgekoppelt sind, und wenn die Reibschlusselemente zur Übertragung einer Drehbewegung der Trennscheiben miteinander in Reibschluss stehen. Auf diese Weise kann die Drehbewegung von einer Trennscheibe auf die andere Trennscheibe übertragen werden. Infolge des Kontakts zwischen den Reibschlusselementen bewegen sich die Reibschlusselemente im Bereich des Reibschlusses mit derselben Geschwindigkeit. Daher ist es bevorzugt, wenn die Reibschlusselemente scheibenförmig ausgebildet sind und zylindrische Reibschlussflächen aufweisen, deren Abstand zur jeweiligen Rotationsachse relativ zueinander identisch ist. Auf diese Weise ist es möglich, die Trennscheiben in einfacher Weise mit derselben Umdrehungsgeschwindigkeit anzutreiben.It is also advantageous if the cutting disks are each coupled in terms of movement to a frictional engagement element, and if the frictional engagement elements are in frictional engagement with one another in order to transmit a rotational movement of the cutting disks. In this way, the rotary movement can be transmitted from one cutting wheel to the other cutting wheel. As a result of the contact between the frictional engagement elements, the frictional engagement elements move at the same speed in the area of the frictional engagement. It is therefore preferred if the frictional engagement elements are disk-shaped and have cylindrical frictional engagement surfaces, their distance from the respective axis of rotation is identical relative to each other. In this way it is possible to drive the cutting disks in a simple manner at the same speed of rotation.
Es ist ferner bevorzugt, dass die zylindrischen Reibschlussflächen einen Radius aufweisen, der zumindest im Wesentlichen dem Radius der Trennscheiben entspricht. Hierdurch wird ein vergleichsweise einfacher Aufbau der Trenneinrichtung ermöglicht. Außerdem ergeben sich in Verbindung mit nachfolgend beschriebenen Ausgestaltungen der Erfindung weitere Vorteile.It is also preferred that the cylindrical frictional engagement surfaces have a radius which at least substantially corresponds to the radius of the cutting disks. This enables a comparatively simple construction of the separating device. In addition, there are further advantages in connection with the embodiments of the invention described below.
Es ist insbesondere bevorzugt, dass die Reibschlusselemente in Verlaufsrichtung des Finishbands gesehen benachbart zu dem Trennbereich angeordnet sind. Auf diese Weise erfolgt die Drehmomentübertragung unmittelbar benachbart zu dem Trennbereich. Dies ist insbesondere dann vorteilhaft, wenn die Reibschlusselemente Reibschlussflächen aufweisen, welche als Klemmflächen für das Finishband wirksam sind. In diesem Fall erfüllen die Reibschlussflächen zusätzlich zu ihrer Funktion der Drehmomentübertragung eine weitere Funktion, nämlich die Fixierung eines zu durchtrennenden Finishbands zwischen den Reibschlussflächen.It is particularly preferred that the frictional engagement elements are arranged adjacent to the separating area, viewed in the direction of the finish belt. In this way, the torque is transmitted immediately adjacent to the separation area. This is particularly advantageous when the frictional engagement elements have frictional engagement surfaces which act as clamping surfaces for the finishing belt. In this case, in addition to their function of torque transmission, the frictional engagement surfaces fulfill a further function, namely the fixing of a finishing tape to be severed between the frictional engagement surfaces.
Wenn, wie oben erläutert, die Reibschlussflächen zumindest im Wesentlichen denselben Radius haben, wie die Wirkbereiche der Trennelemente, entspricht die über die Breite des Finishbands anliegende Schnittgeschwindigkeit zumindest ungefähr der Vorschubgeschwindigkeit des Finishbands in Breitenrichtung des Finishbands gesehen. Auf diese Weise wird das Finishband so geklemmt und fixiert, dass das Finishband während des Durchtrennungsvorgangs keinen weiteren Antriebskräften ausgesetzt ist, also bezogen auf die Trenneinrichtung weder zu schnell angezogen noch in entgegengesetzter Richtung abgestoßen wird.If, as explained above, the frictional engagement surfaces have at least essentially the same radius as the active areas of the separating elements, the cutting speed across the width of the finishing belt corresponds at least approximately to the feed speed of the finishing belt viewed in the width direction of the finishing belt. In this way, the finishing belt is clamped and fixed in such a way that the finishing belt is not exposed to any further driving forces during the cutting process, i.e. is neither attracted too quickly with respect to the cutting device nor pushed off in the opposite direction.
In vorteilhafter Weise ist im Sammelbereich ein Sammelbehälter zum Sammeln von abgetrennten Finishbandabschnitten angeordnet. Ein solcher Sammelbehälter muss nicht notwendigerweise in der Lage sein, Finishbandabschnitte einer vollständigen Vorratsrolle aufzunehmen. Es kann sich auch um einen kleinen, leichten und somit einfacher handhabbaren Sammelbehälter handeln.A collecting container for collecting separated finishing belt sections is advantageously arranged in the collecting area. Such a collecting container does not necessarily have to be able to accommodate finishing tape sections of a complete supply roll. It can also be a small, light and therefore easier to handle collecting container.
Bei dem Sammelbehälter kann es sich beispielsweise um eine Sammelrinne handeln. Der Sammelbehälter kann stationär an der Bandfinishvorrichtung angeordnet sein, sodass er bezogen auf ein Maschinengestell der Bandfinishvorrichtung nicht bewegbar ist. Es ist aber auch denkbar, dass der Sammelbehälter innerhalb des Sammelbereichs beweglich angeordnet ist, beispielsweise entlang einer parallel zu einer Werkstückachse verlaufenden Bewegungsachse.The collecting container can be, for example, a collecting channel. The collecting container can be arranged in a stationary manner on the tape finishing device, so that it cannot be moved with respect to a machine frame of the tape finishing device. However, it is also conceivable that the collecting container is arranged movably within the collecting area, for example along a movement axis running parallel to a workpiece axis.
Für einen einfachen Aufbau der Bandfinishvorrichtung ist es bevorzugt, wenn das zu durchtrennende Finishband in dem Sammelbereich in einer vertikalen Richtung verläuft. Ein solches Finishband kann besonders einfach durchtrennt werden, insbesondere dann, wenn die erfindungsgemäße Trenneinrichtung in einer horizontalen Trennebene wirksam ist.For a simple construction of the tape finishing device, it is preferred if the finishing tape to be cut runs in a vertical direction in the collecting area. Such a finishing tape can be severed particularly easily, in particular when the severing device according to the invention is effective in a horizontal severing plane.
Es ist denkbar, dass die Trenneinrichtung bezogen auf ein Maschinengestell der Bandfinishvorrichtung stationär angeordnet ist. In diesem Fall ist es möglich, zu durchtrennende Finishbänder der Trenneinrichtung zuzuführen, indem Führungseinrichtungen, welche das Finishband in dem Arbeitsbereich führen, mittels eines Führungseinrichtungsantriebs angetrieben werden, um das Finishband in Breitenrichtung des Finishbands zu bewegen. Für diesen Fall ist es bevorzugt, wenn eine Vorschubgeschwindigkeit des Finishbands in einer zu der Werkstückachse parallelen Richtung zumindest in etwa gleich einer über die Breite des Finishbands anliegenden Schnittgeschwindigkeit der Trenneinrichtung ist. Auf diese Weise ist das Finishband während des Durchtrennungsvorgangs keinen weiteren Antriebskräften ausgesetzt ist, wird also bezogen auf die Trenneinrichtung weder zu schnell angezogen noch in entgegengesetzter Richtung abgestoßen.It is conceivable that the cutting device is arranged in a stationary manner in relation to a machine frame of the tape finishing device. In this case, it is possible to feed the finishing belts to be cut to the cutting device by driving guide devices which guide the finishing belt in the work area by means of a guide device drive in order to move the finishing belt in the width direction of the finishing belt. In this case, it is preferred if a feed speed of the finishing belt in a direction parallel to the workpiece axis is at least approximately equal to a cutting speed of the cutting device across the width of the finishing belt. In this way, the finishing belt is not exposed to any further driving forces during the severing process, that is to say it is neither attracted too quickly in relation to the severing device nor repelled in the opposite direction.
Es ist auch denkbar, dass eine Vorschubeinrichtung vorgesehen ist, mittels welcher die Trenneinrichtung in zu der Werkstückachse paralleler Richtung bewegbar ist. Auf diese Weise kann die Trenneinrichtung (ggf. mit einem mit ihr verbundenen Sammelbehälter) parallel zu der Werkstückachse verfahren werden, sodass eine Durchtrennung eines Finishbands vollständig unabhängig von dem Vorschub und der Position einer Führungseinrichtung zur Führung des Finishbands im Arbeitsbereich erfolgen kann.It is also conceivable that a feed device is provided, by means of which the separating device can be moved in a direction parallel to the workpiece axis. In this way, the cutting device (possibly with a collecting container connected to it) can be moved parallel to the workpiece axis so that a finishing belt can be cut completely independently of the advance and the position of a guide device for guiding the finishing belt in the work area.
Vorzugsweise ist eine Vorschubgeschwindigkeit der Vorschubeinrichtung zumindest in etwa gleich einer über die Breite des Finishbands anliegenden Schnittgeschwindigkeit der Trenneinrichtung. Auf diese Weise ist das Finishband während des Durchtrennungsvorgangs keinen weiteren Antriebskräften ausgesetzt ist, wird also bezogen auf die Trenneinrichtung weder zu schnell angezogen noch in entgegengesetzter Richtung abgestoßen.Preferably, a feed speed of the feed device is at least approximately equal to a cutting speed of the cutting device across the width of the finishing belt. In this way, the finishing belt is not exposed to any further driving forces during the severing process, that is to say it is neither attracted too quickly in relation to the severing device nor repelled in the opposite direction.
Es ist möglich, dass die Vorschubeinrichtung eine stationäre Antriebseinrichtung umfasst, also beispielsweise einen Motor, der bezogen auf das Maschinengestell der Bandfinishvorrichtung ortsfest ist. Die Antriebsbewegung eines solchen Motors kann über Getriebeteile (bspw. einen Antriebsriemen) auf die Trenneinrichtung übertragen werden.It is possible for the feed device to comprise a stationary drive device, that is to say for example a motor which is stationary in relation to the machine frame of the tape finishing device. The drive movement of such a motor can be transmitted to the separating device via gear parts (e.g. a drive belt).
Bei der Vorschubeinrichtung handelt es sich vorzugsweise um einen Linearantrieb, beispielsweise einen elektrischen Linearmotor, dessen Läufer mit der Trenneinrichtung verbunden ist. Bei dem Linearantrieb handelt es sich insbesondere um einen kolbenstangenlosen Pneumatikzylinder.The feed device is preferably a linear drive, for example an electric linear motor, the rotor of which is connected to the separating device. The linear drive is, in particular, a pneumatic cylinder without a piston rod.
Es ist auch denkbar, eine gemeinsam mit der Trenneinrichtung bewegbare Antriebseinrichtung vorzusehen, beispielsweise einen an der Trenneinrichtung angeordneten Drehantrieb, der ein Zahnrad antreibt. Das Zahnrad kämmt mit einer Zahnstange, die sich parallel zu der Bewegungsachse der erstreckt, sodass die Drehbewegung des Zahnrads in eine Vorschubbewegung der Trenneinrichtung entlang der Bewegungsachse umgesetzt wird.It is also conceivable to provide a drive device which can be moved together with the separating device, for example a rotary drive which is arranged on the separating device and which drives a gearwheel. The toothed wheel meshes with a toothed rack which extends parallel to the axis of movement of the, so that the rotary movement of the toothed wheel is converted into a feed movement of the separating device along the axis of movement becomes.
Schließlich ist es bevorzugt, wenn eine Getriebeeinrichtung zur Übersetzung einer Vorschubbewegung der Trenneinrichtung in eine Antriebsbewegung des Trennelements vorgesehen ist. Auf diese Weise kann auf einen zusätzlichen motorischen Antrieb für das Trennelement verzichtet werden. Die Getriebeeinrichtung umfasst beispielsweise ein mit einem Trennelement drehfest gekoppeltes Zahnrad, das von einem Antriebszahnrad angetrieben wird. Das Antriebszahnrad wird beispielsweise direkt durch einen vorstehend genannten Drehantrieb angetrieben oder durch Eingriff in eine sich parallel zu der Bewegungsachse der Trenneinrichtung erstreckende Zahnstange. In beiden Fällen geht eine Vorschubbewegung der Trenneinrichtung mit einer Drehbewegung des Trennelements einher. Somit wirkt die Antriebseinrichtung der Vorschubeinrichtung als motorischer Antrieb für das Trennelement.Finally, it is preferred if a gear device is provided for converting a feed movement of the separating device into a drive movement of the separating element. In this way, there is no need for an additional motor drive for the separating element. The transmission device comprises, for example, a gearwheel which is coupled in a rotationally fixed manner to a separating element and which is driven by a drive gearwheel. The drive gear is driven, for example, directly by a rotary drive mentioned above or by engagement in a rack extending parallel to the axis of movement of the separating device. In both cases, an advance movement of the separating device is accompanied by a rotary movement of the separating element. The drive device of the feed device thus acts as a motor drive for the separating element.

Eine Ausführungsform einer Bandfinishvorrichtung ist in der Zeichnung insgesamt mit dem Bezugszeichen 10 bezeichnet. Die Vorrichtung 10 umfasst ein Maschinengestell 12 zur Anordnung eines Rotationsantriebs 14 und eines Oszillationsantriebs 16.One embodiment of a tape finishing device is designated as a whole by the
Der Rotationsantrieb 14 dient dazu, ein Werkstück 18 um eine Werkstückachse 20 rotatorisch anzutreiben. Der Oszillationsantrieb 16 dient dazu, dieser Rotationsbewegung des Werkstücks 18 eine Oszillationsbewegung zu überlagern. Bei dieser Oszillationsbewegung bewegt sich das Werkstück 18 in zu der Werkstückachse 20 paralleler Richtung hin und her.The
Bei der finishend zu bearbeitenden Werkstückoberfläche kann es beispielsweise um die Umfangsfläche eines Hubzapfens 22 handeln.The workpiece surface to be finished can be, for example, the circumferential surface of a
Zur finishenden Bearbeitung einer Werkstückoberfläche umfasst die Bandfinishvorrichtung 10 ein Finishband 24, welches aus einem Finishbandvorrat 26, beispielsweise einer Vorratsrolle, zugeführt wird. Zur Führung des Finishbands 24 ist eine Führungseinrichtung 28 vorgesehen. Diese umfasst in an sich bekannter Weise Andrückelemente, welche das Finishband 24 in einem Arbeitsbereich 30 gegen die finishend zu bearbeitende Werkstückoberfläche andrücken.For the finishing machining of a workpiece surface, the
Aus dem Arbeitsbereich 30 heraus gelangt verbrauchtes Finishband zu einem Sammelbereich 32. In diesem Sammelbereich ist eine Trenneinrichtung 34 angeordnet.Used finishing tape passes out of the
Es ist möglich, dass die Trenneinrichtung 34 bezogen auf das Maschinengestell 12 stationär angeordnet ist. In diesem Fall kann ein Vorschub des Finishbands 24 quer zu dessen Verlaufsrichtung (also in Breitenrichtung des Finishbands) im Bereich der Trenneinrichtung 34 dadurch erreicht werden, dass die Führungseinrichtungen 28 parallel zur Werkstückachse 20 verfahren werden, beispielsweise mittels eines Schlittens 36.It is possible for the separating
Es versteht sich, dass eine Bandfinishvorrichtung 10 üblicherweise eine Mehrzahl von Führungseinrichtungen 28 aufweist, welche parallel zueinander angeordnet sind, sodass entlang der Werkstückachse 20 gesehen gleichzeitig mehrere Finishbänder 24 mit unterschiedlichen Werkstückoberflächen eines Werkstücks 18 in Eingriff gebracht werden können.It goes without saying that a
Zur nachfolgenden Erläuterung des Aufbaus und der Funktionsweise der Trenneinrichtung 34 wird auf die
Die Trenneinrichtung 34 weist zwei Trennelemente 50 und 52 auf, welche in Form von zwei Trennscheiben 54 und 56 ausgebildet sind. Die Trennscheiben 54 und 56 wirken mit jeweiligen Schneidkanten in einem Trennbereich 58 zusammen. Eine der Schneidkanten wird dadurch gebildet, dass die Trennscheibe 54 als Tellermesserscheibe ausgebildet ist. Die andere Schneidkante wird dadurch gebildet, dass die Trennscheibe 56 als Nutmesserscheibe ausgebildet ist.The separating
Die Trennscheiben 50 und 52 rotieren um zueinander parallele Rotationsachsen 64 und 66, die parallel zu einer Verlaufsrichtung 68 des Finishband 24 in dem Sammelbereich 32 orientiert sind. Zur Erzeugung einer Andrückkraft in zu der Verlaufsrichtung 68 paralleler Richtung ist eine Druckfeder 70 vorgesehen. Diese drückt die Schneidkante der Trennscheibe 54 gegen die Schneidkante der Trennscheibe 56.The cutting
Zur Drehlagerung der Trennscheiben 54, 56 um die Drehachsen 64, 66 sind Lagerkörper 72, 74 vorgesehen. Diese sind jeweils mit Schlitten 76, 78 verbunden, welche relativ zu Schlittenträgern 80, 82 entlang von Schlittenachsen 84, 86 verfahrbar sind. Die Schlittenachsen 84, 86 sind parallel zueinander ausgerichtet; insbesondere fluchten die Achsen 84 und 86 miteinander. Die Achsen 84 und 86 sind senkrecht zu den Drehachsen 64 und 66 und senkrecht zu der Werkstückachse 20 orientiert.
Die Schlitten 76, 78 sind parallel zu den Schlittenachsen 84, 86 mittels Zugfedern 88 in Richtung aufeinander zu kraftbeaufschlagt. Eine entsprechende Gegenkraft wird in einem Bereich 90 erzeugt, in welchem zwei Reibschlusselemente 91 und 92 reibschlüssig aneinander anliegen. Die Reibschlusselemente 91 und 92 sind jeweils drehfest mit einer der Trennscheiben 54, 56 gekoppelt. Die Reibschlusselemente 91, 92 weisen zylindrische Reibschlussflächen 94, 96 auf, die in dem Bereich 90 miteinander reibschlüssig in Kontakt stehen. Die Reibschlussflächen 94, 96 sind beispielsweise aus einem Kunststoff hergestellt, insbesondere aus Vulkollan®.The
Der Bereich 90 ist entlang der Verlaufsrichtung 68 des Finishbands 24 gesehen unmittelbar benachbart zu dem Trennbereich 58 angeordnet.The
Zur Erzeugung einer Drehbewegung der Trennscheiben 54 und 56 ist eine Getriebeeinrichtung 98 vorgesehen, die eine Bewegung der Trenneinrichtung 34 entlang der Bewegungsachse 40 in eine Antriebsbewegung der Trennscheiben 54, 56 übersetzt. Die Getriebeeinrichtung 98 umfasst eine mit dem Grundkörper 42 fest verbundene und sich längs der Schiene erstreckende Zahnstange 100. Die Zahnstange 100 wirkt mit einem Zahnrad 102 zusammen, welches um eine Rotationsachse 104 drehbar an der Trenneinrichtung 34 gelagert ist. Eine Drehbewegung des Zahnrads 102 wird durch kämmenden Eingriff auf ein weiteres Zahnrad 106 übertragen, welches drehfest mit dem Reibschlusselement 92 und der Trennscheibe 56 verbunden ist.To generate a rotary movement of the cutting
Eine Bewegung der Trenneinrichtung 34 längs der Bewegungsachse 40 mittels der Vorschubeinrichtung 44 führt dazu, dass das Zahnrad 102 auf der Zahnstange 100 abwälzt. Die daraus entstehende Drehbewegung des Zahnrads 102 wird in gegensinniger Rotationsrichtung auf das Zahnrad 106 übertragen, welches somit um die Rotationsachse 66 rotiert, und zwar gemeinsam mit dem Reibschlusselement 92 und der Trennscheibe 56.A movement of the separating
Mittels des Reibschlusses zwischen dem Reibschlusselement 92 und dem Reibschlusselement 91 wird die Drehbewegung der Trennscheibe 56 in eine gegenläufige Drehbewegung um die Achse 64 übertragen, bei welcher die Trennscheibe 54 rotiert.By means of the frictional engagement between the
In
Wenn die Trenneinrichtung 34 in Vorschubrichtung 108 in Richtung auf das Finishband 24 verfahren wird, gelangt das Finishband 24 in dem Eingriffbereich 90 zwischen den Reibschlussflächen 91 und 92 und wird aus Sicht des Finishbands 24 in den Eingriffsbereich 90 hineingezogen, sodass die Reibschlussflächen 94, 96 als Klemmflächen für das Finishband 24 wirksam sind. Auf diese Weise ist das zu durchtrennende Finishband 24 in dem Bereich 90 fixiert und kann unmittelbar benachbart dazu in dem Trennbereich 58 durchtrennt werden. Da die Schneidkanten der Trennscheiben 54, 56 im Wesentlichen denselben Durchmesser aufweisen wie die zylindrischen Reibschlussflächen 94, 96, ist die über die Breite des Finishbands 24 anliegende Schnittgeschwindigkeit zumindest in etwa gleich der Umfangsgeschwindigkeit der Reibschlussflächen 94, 96 in dem Bereich 90. Auf diese Weise kann das Finishband 24 weitestgehend querkraftfrei durchtrennt werden.When the separating
Von dem Finishband 24 abgetrennte Abschnitte können in einem Sammelbehälter 112 gesammelt werden. Bei dem Sammelbehälter 112 handelt es sich beispielsweise um eine Sammelrinne 114, welche gemeinsam mit der Trenneinrichtung 34 entlang der Bewegungsachse 40 bewegbar ist. In der Sammelrinne 114 gesammelte Finishbandabschnitte können von dort aus entsorgt werden oder aber in der Sammelrinne 114 lediglich zwischengespeichert und von dort einem stationären Zusatzsammelbehälter 116 zugeführt werden. Für die Überführung von Finishbandabschnitten aus der Sammelrinne 114 in den Zusatzsammelbehälter 116 können beispielsweise Schieber oder Gebläse verwendet werden. Es ist auch denkbar, dass sich die Sammelrinne 114 entlang der gesamten Länge der Schiene 42 erstreckt.Sections cut off from the finishing
Eine Entsorgung der Sammelrinne 114 kann mittels eines Förderbands. Ein solches Förderband erstreckt sich vorzugsweise entlang eines Bodens der Sammelrinne 114.The collecting
Auch eine manuelle Entsorgung der Sammelrinne 114 ist möglich.Manual disposal of the collecting

Die Achsen 64 und 66 sind jeweils an etwa parallel zu der Werkstückachse 20 erstreckenden Trägern 120, 122 angeordnet. Die Träger 120, 122 sind in einander zugewandte Richtungen mit Zugfedern 88 beaufschlagt. Die entsprechende Gegenkraft entsteht in dem Eingriffsbereich 90 durch Druckkontakt der Reibschlusselemente 90 und 92.The
Um im Wartungsfall die Trennscheiben 54 und 56 in einer zu der Werkstückachse 20 senkrechten Richtung voneinander entfernen zu können, ist eine Abstandseinrichtung 124 vorgesehen. Diese weist eine Spindelachse 126 auf, die sich an dem Träger 120 abstützt und gegen den Träger 122 wirksam ist, sodass die Träger 120 und 122 entgegen der der Kraft der Zugfedern 88 auseinander gedrückt werden können. Vorzugsweise ist einer der Träger ortsfest, beispielsweise der Träger 120, während der andere Träger beweglich ist, beispielsweise der Träger 122.In order to be able to remove the cutting
