Definitions
- the invention relates to a brush assembly with a rotatably driven brush holder and a ring brush with a bristle ring with outwardly projecting bristles, and with a dipping into the rotating bristle ring stop means, wherein with the aid of the stop means, the bristles are braked for a certain time, so that after their release the kinetic energy stored thereby is used for additional beating processing of a surface of a material by the bristles.
- the invention is based on the technical problem of further developing such a brushing unit so that, in addition, the possibility of grinding the bristles is created, namely with a structurally simple and cost-effective construction.
- a generic brush assembly is characterized in the invention in that the stop means is also designed as an abrasive body for the bristles, wherein between the two functions, that is between the stopper function and the Schleiffunktion, in accordance with a direction of rotation of the ring brush and / or a positioning position of the stop means in comparison to the bristle rim is distinguished.
- the stopping means in addition to the obligatory stopping means, initially no additional grinding body is used, but rather the stopping means is designed as an abrasive body for the bristles.
- the stop means assumes essentially the same function as in the EP 1 834 733 B1 has been described. Because with the help of the stop means braked the bristles for a certain time, so that after their release (from the stop means), the kinetic energy stored thereby for additional beating processing of a surface of a material is used by the bristles.
- the stop means also takes over a Schleiftician. As part of this grinding function, the bristles undergo a grinding process. This is usually - but not limiting - so that the bristles learn on their seen in the working direction back with the help of the grinding wheel or the stop means a back-grinding processing.
- the stop means is advantageously designed such that different surface areas of the stop means are responsible for the various functions described.
- the surface of the stopper mainly has a stopper portion and a grinding portion.
- the grinding area can be designed or formed so that it reliably exerts its abrasive function by applied to the stopper abrasive particles of, for example, diamond, corundum or similar abrasive.
- the grinding area can also be defined on or on the stop means that the stop means in the grinding area is roughened especially or undergoes a special surface treatment.
- the grinding area is designed so that it is particularly suitable for grinding the bristles and here mostly the bristle tips. The invention is based on the recognition that the bristles and in particular the bristle tips after a certain processing time "dull" and must be “sharpened” again.
- the grinding area of the stop means is available.
- This back grinding treatment takes into account the fact that the removal of material at the bristle tip is reduced to a minimum and yet a desired tip formation is achievable.
- the invention is based on the fact that the respective bristles or their bristle tips on its leading edge by the impact treatment of the surface of the material compared to the trailing edge are already more worn. Now, if the trailing edge undergoes the described grinding machining, so the invention takes this circumstance particularly into account.
- the processing of the trailing edge means nothing else than that the bristles (at their bristle tip) on their seen in the working direction backside undergo the described looping with the aid of the grinding area of the stop means.
- the ring brush changes its direction of rotation.
- the ring brush can rotate in a substantially clockwise or counterclockwise direction.
- the respective direction of rotation now corresponds on the one hand to the stopper function and on the other hand to the grinding function of the stop means.
- the rotation of the ring brush may be counterclockwise to the stopper function.
- a clockwise rotation of the ring brush causes the stop means to take over its grinding function. In this case, you will always place the stopper so that it dips into the rotating crown of bristles.
- the stop means may be designed stationary.
- the stop means is adjusted or is designed adjustable in comparison to the bristle rim.
- the adjustment can basically be done during its stopper function and also during its Schleiffunktion.
- the adjustment of the stop means of course in a period between these two functions is conceivable and is encompassed by the invention. In most cases, however, the design will be such that different positioning positions of the stop means in comparison to the bristle rim belong to the described two functions.
- the stopper function of the stop means so that the stop means is immersed with its entire cross section in the bristle rim.
- the stopper area defined on the surface of the stop means corresponds to nearly half or more than half of said surface. If, on the other hand, the stopping means assumes the grinding function, then the stopping means only partially penetrates the bristle rim with its cross section. In most cases, the bristles slide more or less tangentially along the grinding area when taking on the grinding function of the stopping means. Thereby, the grinding area may be formed relatively small on the surface of the stop means and typically occupies about 10% to 50% of the surface, whereas the stopper area corresponds to about 30% to 80% of the surface of the stop means.
- the stopper function can be done to distinguish between on the one hand the stopper function and on the other hand, the Schleiffunktion a combination of both measures.
- the stopper function for the Schleussuntation (and vice versa) not only changed the direction of rotation of the ring brush, but also the position of the stop means.
- This is preferably done. That is, when changing from the stopper function to the Schleussuntation the ring brush is stopped in the example case with respect to the original rotation in the counterclockwise direction and operated in the reverse direction clockwise in order to represent the Schleufunktion.
- the stop means is advantageously connected to a boom which is pivotally articulated to a machine housing.
- the boom is usually an eccentric boom.
- the boom has at least two stops or it is associated with two stops. It serves a stop for taking the
- Stopper function and another stop for taking the Schleufunktion are designed as a stopper stop on the one hand and a grinding stop on the other hand.
- the invention also relates to a rotary brush tool, which is equipped with a machine housing and a drive unit for the brush unit described.
- a method for processing a surface of a material by means of the described brush assembly is included.
- a brush assembly, an associated rotary brush tool and a method for processing a surface of a material using the brush assembly are described, with the help of a simple and durable machining of the surface succeeds.
- comparable roughness depths are achieved and observed, as they are also possible during (sand) blasting and can be realized.
- expensive drive devices are eliminated and, in particular, no blasting agent has to be disposed of.
- particularly long service lives are observed because the bristles can be reground. All this is possible with the help of the stop means, which fills a double function, namely the described stopper function and wiper function.
- the main benefits are the main benefits.
- a rotary brush tool is shown, which is equipped with a machine housing 1 and a merely indicated and received therein drive unit 2 for a brush unit 3.
- the brush assembly 3 has a ring brush 4, 5, which is composed in the embodiment and not limiting of a brush belt 4 and attached thereto and outwardly projecting bristles 5.
- the bristles 5 extend radially in comparison to a center of rotation or a rotation axis 6 and rise substantially perpendicularly on a surface of the ring brush 4, 5 or a surface of the brush belt 4.
- the bristles 5 are U-shaped bristles 5 made of steel, which are inserted into merely indicated receiving bores 7 in the brush belt 4 and inserted therethrough (cf. Fig. 2 ).
- the bristles 5 form a bristle ring 8 with interruptions 9.
- Die Ring brush 4, 5 is supported by a rotationally driven by means of the drive unit 2 brush holder 10, 11.
- the brush holder 10, 11 is composed of two end plates 10, which are held by a spacer bush 11 in a spaced position to each other. In the present case, the spacer bushing 11 can also be dispensed with. Then takes over the brush belt 4 of the ring brush 4, 5, the function of the spacer bushing 11.
- the spacer bushing 11 can also be dispensed with.
- Fig. 1 Based on Fig. 1 can be seen further that the two end plates 10 are equipped with axial webs 12, with which they overlap the ring brush 4, 5 and the brush belt 4 in the region of the interruptions 9. Both end plates 10 are braced against each other with the spacer bush between them, respectively, the brush belt 4, 11 including attached bristles 5. This ensures a secure hold of the ring brush 4, 5 on a drive pin 13 of the drive unit 2 of the rotary brush tool.
- Fig. 1 are three evenly distributed over the circumference of the brush belt 4 interruptions 9 realized.
- a dipping into the rotating bristle rim 8 stop means 14 is realized.
- the stop means 14 are not restrictive, for example, a cylindrical pin 14, which is connected via a boom 15 to the machine housing 1 of the rotary brush tool.
- the stop means 14 or the pin 14 is arranged parallel to the drive pin 13 of the drive unit 2 or parallel to the axis of rotation 6 on the boom 15 and connected to this example by screwing.
- the length of the stop means 14 is chosen so that it substantially corresponds to the width of the brush belt 4, consequently the stop means 14 axially or in comparison with the ring brush 4, 5 is not or only insignificantly.
- the stop means 14 can assume two functions, namely a stopper function, as in the Fig. 2 is shown and also a Schleiffunktion, like the Fig. 3 shows. That is, the stop means 14 is at the same time designed as an abrasive body 14 for the bristles 5.
- the outer surface 16 of the stop means 14, which is designed as a cylinder jacket in the example, has two regions. In fact, on the one hand, a stopper region 16a and on the other hand a grinding region 16b are provided.
- the outer surface 16 of the stop means 4 is thus composed of the stopper region 16a and the grinding region 16b, which complement each other more or less and generally form the outer surface 16 of the stop means 14 as a whole.
- the stopper region 16a occupies approximately 30% to 80% of the outer surface 16
- the abrasive region 16b occupies approximately 10% to 50% of the outer surface 16 of the stop means 14.
- the stopper region 16a and the grinding region 16b are arranged relative to one another in such a way that they do not overlap but rather join one another with or without a distance.
- the bristles 5 either interact only with the stopper region 16a or only with the grinding region 16b.
- the stopper function of the brushing unit 3 or of the rotary brushing tool as a whole whereas the latter interaction corresponds to the Schleufunktion belongs.
- the stopper region 16a and / or the grinding region 16b can be integrally formed on the stop means 14 or additionally attached thereto. This can be achieved, for example, by screwing on sleeves or plates which define the stopper region 16a in question and / or the grinding region 16b.
- the stop means 14 operates in principle as in the introductory already referred to EP 1 834 733 B1 has been described in detail.
- the stopping means 14 immersed in the rotating bristle rim 8, with its entire cross section, a.
- the stopper function corresponds to a counterclockwise rotation of the ring brush 4, 5 about the axis of rotation 6.
- the bristles 5 are decelerated in the region of the stop means 14 for a certain time. If the bristles 5 become free of the stop means 14, the kinetic energy stored by the bristles 5 and / or the brush belt 4 is utilized by the bristles 5 for the additionally beating processing of a surface of a material 19.
- the bristles 5 have in their direction of rotation R indicated by an arrow in the counterclockwise direction Fig. 2 over leading beveled bristle tips 5 '. Of course this is not mandatory.
- the brush belt 4 primarily undergoes deformation. Because the usually perpendicular to the brush belt 4 upstanding bristles 5 are forced into an acute-angled position compared to the surface of the brush belt 4. From a certain acute angle, the bristle tips 5 'of the stop means 14 can not be retained, so that the bristles snap back 5 and in this process, the bristle tips 5' in the Fig. 2 Described circular arc 20 describe which deviates from the outer surface 17 of the bristle rim 8 and the associated circular arc. In the relevant figure, one also recognizes a protective cover 18 for the entire brushing unit 3.
- the stop means 14 can also be a Schleiffunktion according to the illustration Fig. 3 fill out.
- the Abrasive function corresponds in contrast to the stopper function Fig. 2 to that the ring brush 4, 5 now rotates clockwise. This is again made clear by the arrow with the direction of rotation R.
- the change from the stopper function to the Schleiffunktion and vice versa thus corresponds to a reversal of the rotating ring brush 4, 5.
- the stop means 14 experienced an adjustment, such as a comparison of Fig. 2 and 3 makes it clear.
- the stopper function belonging to the actuating position of the stop means 14 shown in solid, while belonging to the Schleypuntechnisch actuating position undergoes a dash-dotted representation.
- the stopping means 14 immersed in the abrasive function only with its grinding area 16b in the bristle rim 8.
- the bristles 5 are sanded on their bristle tips 5 'on their rear side viewed in the working direction.
- this is only to be understood as an example, wherein the bristles 5 can in principle also be sanded to a greater length.
- FIG. 2 A comparison of Fig. 2 and 3 with the associated functional positions makes it clear that the stop means 14 is adjusted radially and / or tangentially. In fact, the stopping means 14 experiences an eccentric adjustment.
- the stop means 14 is connected to the boom 15, which in turn is pivotally hinged to the machine housing 1.
- the boom 15 is shown in the illustration after the Fig. 4 and 5 around an eccentric 15.
- This eccentric 15 is equipped with a bearing eye 21 which is penetrated by a bearing pin or a bearing plate 22 off-center.
- the bearing plate or the bearing pin 22 is connected to the machine housing 1.
- the boom or eccentric arm 15 perform an eccentric pivoting movement, which in the Fig. 2 is indicated, if one compares the solid shown stopper function with the dash-dotted sanding function.
- the stopper 23 is formed as a stopper stopper 23, whereas the stopper 24 constitutes a grinding stopper 24.
- the stopper stop 23 ensures that the boom or eccentric arm 15 assumes the stopper function or the corresponding functional position.
- the grinding stop 24 ensures that the stopping means 14 defines the grinding function or the corresponding functional position.
- the stopping means 14 is converted by the running against bristles 5 depending on the direction of rotation of the ring brush 4, 5 in the stopper function or the Schleiffunktion.
- the change from the stopper function to the sanding function and vice versa takes place in such a way that initially the direction of rotation of the ring brush 4, 5 is changed.
- the ring brush 4, 5 thus undergoes a reversal of direction.
- By changing the direction of rotation R of the ring brush 4, 5 and the stop means 14 is adjusted. Because the bristles 5 go against the stop means 14 and pivot it compared to the machine housing 1. This process is continued until the corresponding stop 23, 24 blocks further pivotal movement of the stop means 14.
- the bristles 5 or their bristle tips 5 'slide more or less tangentially along the grinding area 16b of the outer surface 16 of the stop means 14, that in an enlarged view in FIG Fig. 3 will be shown.
- This grinding region 16b may have an abrasive coating or has been processed in such a way that the bristle tips 5 'undergo a back-grinding treatment on their rear side seen in the working direction or in the clockwise direction in the example case.
- the stopper function For this purpose, only the ring brush 4, 5 perform a new direction of rotation reversal.
- the ring brush 4, 5 is again rotated in the counterclockwise direction, as the Fig. 2 represents.
- This reversal of rotation has the consequence that the running against the stop means 14 bristles 5, the stop means 14 with apply a force counterclockwise.
- the stopper 14 becomes in accordance with its solid position Fig. 3 or the dot-dashed position in the Fig. 2 in the solid line position after Fig. 2 transferred. This happens until the boom 15 reaches the stopper stop 23.
- the stopper stop 23 prevents further movements of the boom 15 in the same direction.
- the protective cover 18 and / or the boom 15 may be equipped with fasteners which allow a different and detachable fixing to the machine housing 1.
- the protective cover 18 and / or the boom 15 and / or the ring brush 4, 5 are designed to be stretchable and fixed in different plug positions.

Description
Die Erfindung betrifft ein Bürstenaggregat, mit einem rotativ antreibbaren Bürstenhalter und einer Ringbürste mit einem Borstenkranz mit nach außen abstehenden Borsten, und mit einem in den rotierenden Borstenkranz eintauchenden Stoppmittel, wobei mit Hilfe des Stoppmittels die Borsten für eine bestimmte Zeit abgebremst werden, so dass nach ihrer Freigabe die hierdurch gespeicherte Bewegungsenergie zur zusätzlich schlagenden Bearbeitung einer Oberfläche eines Werkstoffes durch die Borsten genutzt wird.The invention relates to a brush assembly with a rotatably driven brush holder and a ring brush with a bristle ring with outwardly projecting bristles, and with a dipping into the rotating bristle ring stop means, wherein with the aid of the stop means, the bristles are braked for a certain time, so that after their release the kinetic energy stored thereby is used for additional beating processing of a surface of a material by the bristles.
Bei einem Bürstenaggregat des eingangs beschriebenen Aufbaus entsprechend der
Daneben ist durch die
Bei einem Rotationsbürstenwerkzeug entsprechend der
Der Erfindung liegt das technische Problem zugrunde, ein derartiges Bürstenaggregat so weiterzuentwickeln, dass zusätzlich die Möglichkeit zur schleifenden Bearbeitung der Borsten geschaffen wird, und zwar bei einem konstruktiv einfachen und kostengünstigen Aufbau.The invention is based on the technical problem of further developing such a brushing unit so that, in addition, the possibility of grinding the bristles is created, namely with a structurally simple and cost-effective construction.
Zur Lösung dieser technischen Problemstellung ist ein gattungsgemäßes Bürstenaggregat im Rahmen der Erfindung dadurch gekennzeichnet, dass das Stoppmittel zugleich als Schleifkörper für die Borsten ausgebildet ist, wobei zwischen beiden Funktionen, das heißt zwischen der Stopperfunktion und der Schleiffunktion, nach Maßgabe einer Drehrichtung der Ringbürste und/oder einer Stellposition des Stoppmittels im Vergleich zum Borstenkranz unterschieden wird.To solve this technical problem, a generic brush assembly is characterized in the invention in that the stop means is also designed as an abrasive body for the bristles, wherein between the two functions, that is between the stopper function and the Schleiffunktion, in accordance with a direction of rotation of the ring brush and / or a positioning position of the stop means in comparison to the bristle rim is distinguished.
Im Rahmen der Erfindung kommt also neben dem obligatorischen Stoppmittel zunächst einmal kein zusätzlicher Schleifkörper zum Einsatz, sondern ist das Stoppmittel zugleich als Schleifkörper für die Borsten ausgebildet. Das Stoppmittel übernimmt dabei im Wesentlichen die gleiche Funktion, wie sie in der
Zusätzlich zu dieser gleichsam Stopperfunktion übernimmt das Stoppmittel zugleich eine Schleiffunktion. Im Rahmen dieser Schleiffunktion erfahren die Borsten eine schleifende Bearbeitung. Dabei wird meistens - aber nicht einschränkend - so vorgegangen, dass die Borsten auf ihrer in Arbeitsrichtung gesehenen Rückseite mit Hilfe des Schleifkörpers bzw. des Stoppmittels eine hinterschleifende Bearbeitung erfahren. Tatsächlich ist das Stoppmittel im Rahmen der Erfindung vorteilhaft so ausgebildet, dass unterschiedliche Oberflächenbereiche des Stoppmittels für die beschriebenen verschiedenen Funktionen verantwortlich zeichnen.In addition to this as it were stopper function, the stop means also takes over a Schleiffunktion. As part of this grinding function, the bristles undergo a grinding process. This is usually - but not limiting - so that the bristles learn on their seen in the working direction back with the help of the grinding wheel or the stop means a back-grinding processing. In fact, in the context of the invention, the stop means is advantageously designed such that different surface areas of the stop means are responsible for the various functions described.
Das heißt, die Oberfläche des Stoppmittels weist überwiegend einen Stopperbereich und einen Schleifbereich auf. Dabei kann der Schleifbereich so ausgelegt oder ausgebildet werden, dass dieser durch auf das Stoppmittel aufgebrachte Schleifpartikel aus beispielsweise Diamant, Korund oder vergleichbaren Schleifkörpern, seine schleifende Funktion zuverlässig ausübt. Selbstverständlich kann der Schleifbereich auch dadurch an oder auf dem Stoppmittel definiert werden, dass das Stoppmittel im Schleifbereich besonders aufgeraut wird oder eine spezielle Oberflächenbearbeitung erfährt. In jedem Fall ist der Schleifbereich so ausgebildet, dass er sich zur schleifenden Bearbeitung der Borsten und hier meistens der Borstenspitzen besonders eignet. Dabei geht die Erfindung von der Erkenntnis aus, dass die Borsten und insbesondere die Borstenspitzen nach einer bestimmten Bearbeitungszeit "stumpf" werden und wieder "angespitzt" werden müssen.That is, the surface of the stopper mainly has a stopper portion and a grinding portion. In this case, the grinding area can be designed or formed so that it reliably exerts its abrasive function by applied to the stopper abrasive particles of, for example, diamond, corundum or similar abrasive. Of course, the grinding area can also be defined on or on the stop means that the stop means in the grinding area is roughened especially or undergoes a special surface treatment. In any case, the grinding area is designed so that it is particularly suitable for grinding the bristles and here mostly the bristle tips. The invention is based on the recognition that the bristles and in particular the bristle tips after a certain processing time "dull" and must be "sharpened" again.
Hierzu steht erfindungsgemäß der Schleifbereich des Stoppmittels zur Verfügung. Dabei wird man meistens so vorgehen, dass die Borsten im Bereich ihrer Borstenspitze mit Hilfe des Schleifbereiches an dem Stoppmittel eine hinterschleifende Bearbeitung erfahren. Diese hinterschleifende Bearbeitung trägt dem Umstand Rechnung, dass der Materialabtrag an der Borstenspitze auf ein Minimum reduziert wird und dennoch eine gewünschte Spitzenausbildung erreichbar ist. Hierbei geht die Erfindung von der Tatsache aus, dass die jeweiligen Borsten bzw. deren Borstenspitzen an ihrer Vorderflanke durch die schlagende Bearbeitung der Oberfläche des Werkstoffes im Vergleich zur Hinterflanke ohnehin stärker abgenutzt werden. Wenn nun die Hinterflanke die beschriebene schleifende Bearbeitung erfährt, so trägt die Erfindung diesem Umstand besonders Rechnung. Die Bearbeitung der Hinterflanke bedeutet nichts anderes, als dass die Borsten (an ihrer Borstenspitze) auf ihrer in Arbeitsrichtung gesehenen Rückseite die beschriebene hinterschleifende Bearbeitung mit Hilfe des Schleifbereiches des Stoppmittels erfahren.For this purpose, according to the invention, the grinding area of the stop means is available. In this case, one will usually proceed in such a way that the bristles in the region of their bristle tip, with the aid of the grinding region on the stop means, undergo a back-grinding process. This back grinding treatment takes into account the fact that the removal of material at the bristle tip is reduced to a minimum and yet a desired tip formation is achievable. In this case, the invention is based on the fact that the respective bristles or their bristle tips on its leading edge by the impact treatment of the surface of the material compared to the trailing edge are already more worn. Now, if the trailing edge undergoes the described grinding machining, so the invention takes this circumstance particularly into account. The processing of the trailing edge means nothing else than that the bristles (at their bristle tip) on their seen in the working direction backside undergo the described looping with the aid of the grinding area of the stop means.
Um nun zwischen der beschriebenen Stopperfunktion und der Schleiffunktion unterscheiden zu können bzw. zu erreichen, dass die Borsten einerseits mit dem Stopperbereich und andererseits mit dem Schleifbereich des Stoppmittels wechselwirken, sind grundsätzlich zwei verschiedene Vorgehensweisen denkbar und werden von der Erfindung umfasst. Zunächst einmal kann zwischen diesen beiden Funktionen, das heißt der Stopperfunktion und der Schleiffunktion, dadurch unterschieden werden, dass die Ringbürste ihre Drehrichtung ändert. Tatsächlich kann die Ringbürste im Wesentlichen im Uhrzeigersinn oder im Gegenuhrzeigersinn rotieren. Die jeweilige Drehrichtung korrespondiert nun einerseits zu der Stopperfunktion und andererseits zu der Schleiffunktion des Stoppmittels. Beispielsweise mag die Rotation der Ringbürste im Gegenuhrzeigersinn zur Stopperfunktion gehören. Dagegen führt eine Rotation der Ringbürste im Uhrzeigersinn dazu, dass das Stoppmittel seine Schleiffunktion übernimmt. In diesem Fall wird man das Stoppmittel grundsätzlich so platzieren, dass dieses in den rotierenden Borstenkranz eintaucht. Dabei mag das Stoppmittel ortsfest ausgelegt werden.In order to be able to distinguish between the described stopper function and the grinding function or to achieve that the bristles interact on the one hand with the stopper region and on the other hand with the grinding region of the stop means, two different approaches are conceivable and are encompassed by the invention. First of all, a distinction can be made between these two functions, ie the stopper function and the grinding function, in that the ring brush changes its direction of rotation. In fact, the ring brush can rotate in a substantially clockwise or counterclockwise direction. The respective direction of rotation now corresponds on the one hand to the stopper function and on the other hand to the grinding function of the stop means. For example, the rotation of the ring brush may be counterclockwise to the stopper function. In contrast, a clockwise rotation of the ring brush causes the stop means to take over its grinding function. In this case, you will always place the stopper so that it dips into the rotating crown of bristles. In this case, the stop means may be designed stationary.
Es ist alternativ oder zusätzlich aber auch denkbar, dass das Stoppmittel verstellt wird bzw. verstellbar im Vergleich zum Borstenkranz ausgelegt ist. Die Verstellung kann grundsätzlich während seiner Stopperfunktion und auch während seiner Schleiffunktion erfolgen. Daneben ist die Verstellung des Stoppmittels natürlich auch in einem Zeitraum zwischen diesen beiden Funktionen denkbar und wird von der Erfindung umfasst. Meistens wird man die Auslegung jedoch so treffen, dass unterschiedliche Stellpositionen des Stoppmittels im Vergleich zum Borstenkranz zu den beschriebenen beiden Funktionen gehören.It is alternatively or additionally also conceivable that the stop means is adjusted or is designed adjustable in comparison to the bristle rim. The adjustment can basically be done during its stopper function and also during its Schleiffunktion. In addition, the adjustment of the stop means of course in a period between these two functions is conceivable and is encompassed by the invention. In most cases, however, the design will be such that different positioning positions of the stop means in comparison to the bristle rim belong to the described two functions.
So wird man die Stopperfunktion des Stoppmittels meistens so wählen, dass das Stoppmittel mit seinem gesamten Querschnitt in den Borstenkranz eintaucht. Als Folge hiervon korrespondiert der auf der Oberfläche des Stoppmittels definierte Stopperbereich nahezu zur Hälfte oder mehr als der Hälfte der besagten Oberfläche. Nimmt dagegen das Stoppmittel die Schleiffunktion ein, so taucht das Stoppmittel in den Borstenkranz mit seinem Querschnitt nur teilweise ein. Meistens gleiten die Borsten bei Einnahme der Schleiffunktion des Stoppmittels an dem Schleifbereich mehr oder minder tangential entlang. Dadurch kann der Schleifbereich relativ klein auf der Oberfläche des Stoppmittels ausgebildet sein und belegt typischerweise in etwa 10 % bis 50 % der Oberfläche, wohingegen der Stopperbereich zu ca. 30 % bis 80 % der Oberfläche des Stoppmittels korrespondiert.So you will usually choose the stopper function of the stop means so that the stop means is immersed with its entire cross section in the bristle rim. As a result, the stopper area defined on the surface of the stop means corresponds to nearly half or more than half of said surface. If, on the other hand, the stopping means assumes the grinding function, then the stopping means only partially penetrates the bristle rim with its cross section. In most cases, the bristles slide more or less tangentially along the grinding area when taking on the grinding function of the stopping means. Thereby, the grinding area may be formed relatively small on the surface of the stop means and typically occupies about 10% to 50% of the surface, whereas the stopper area corresponds to about 30% to 80% of the surface of the stop means.
Selbstverständlich kann zur Unterscheidung zwischen einerseits der Stopperfunktion und andererseits der Schleiffunktion auch eine Kombination beider Maßnahmen erfolgen. In diesem Fall wird also beim Wechsel von beispielsweise der Stopperfunktion zur Schleiffunktion (und umgekehrt) nicht nur die Drehrichtung der Ringbürste geändert, sondern zusätzlich auch die Stellposition des Stoppmittels. So wird vorzugsweise vorgegangen. Das heißt, beim Wechsel von der Stopperfunktion zur Schleiffunktion wird die Ringbürste im Beispielfall hinsichtlich der ursprünglichen Drehung im Gegenuhrzeigersinn angehalten und mit umgekehrter Drehrichtung im Uhrzeigersinn betrieben, um die Schleiffunktion darstellen zu können.Of course, can be done to distinguish between on the one hand the stopper function and on the other hand, the Schleiffunktion a combination of both measures. In this case, so when changing from example The stopper function for the Schleussunktion (and vice versa) not only changed the direction of rotation of the ring brush, but also the position of the stop means. This is preferably done. That is, when changing from the stopper function to the Schleussunktion the ring brush is stopped in the example case with respect to the original rotation in the counterclockwise direction and operated in the reverse direction clockwise in order to represent the Schleufunktion.
Zugleich ist diese Drehrichtungsumkehr damit verbunden, dass das Stoppmittel aus dem Borstenkranz so weit auftaucht, dass die Borsten bei der anschließenden Schleiffunktion den Schleifbereich gleichsam tangential passieren, wie dies einleitend bereits beschrieben wurde. Das vorteilhaft im Vergleich zum Borstenkranz verstellbar ausgebildete Stoppmittel lässt sich üblicherweise radial und/oder tangential verstellen. Ganz besonders bevorzugt ist eine exzentrische Verstellung des Stoppmittels.At the same time this reversal of rotation is associated with the fact that the stop means from the bristle rim emerges so far that the bristles in the subsequent Schleussunktion the grinding area as it were tangentially, as already described in the introduction. The advantageously compared to the bristle rim adjustable trained stop means can usually be adjusted radially and / or tangentially. Very particular preference is an eccentric adjustment of the stop means.
Dadurch und unabhängig hiervon besteht die Möglichkeit, das Stoppmittel von den angetriebenen Borsten zu verstellen. Das heißt, die Verstellung des Stoppmittels erfolgt nicht mit einem externen zusätzlichen Antrieb, sondern dadurch, dass die Borsten selbst für die Verstellung des Stoppmittels sorgen. Meistens ist die Auslegung so getroffen, dass beim Wechsel von der Stopperfunktion zur Schleiffunktion und umgekehrt die Drehrichtung der Ringbürste geändert wird. Die Drehrichtungsumkehr führt zugleich dazu, dass das Stoppmittel verstellt wird. Zu diesem Zweck ist das Stoppmittel vorteilhaft an einen Ausleger angeschlossen, welcher schwenkbar an ein Maschinengehäuse angelenkt ist. Bei dem Ausleger handelt es sich meistens um einen Exzenterausleger.Thereby, and independently of this, it is possible to adjust the stopping means of the driven bristles. That is, the adjustment of the stop means is not carried out with an external additional drive, but by the fact that the bristles themselves provide for the adjustment of the stop means. In most cases, the design is such that when changing from the stopper function to the sanding function and vice versa, the direction of rotation of the ring brush is changed. The reversal of the direction of rotation also causes the stop means to be adjusted. For this purpose, the stop means is advantageously connected to a boom which is pivotally articulated to a machine housing. The boom is usually an eccentric boom.
Außerdem verfügt der Ausleger über wenigstens zwei Anschläge bzw. ihm sind zwei Anschläge zugeordnet. Dabei dient ein Anschlag zur Einnahme derIn addition, the boom has at least two stops or it is associated with two stops. It serves a stop for taking the
Stopperfunktion und ein anderer Anschlag zur Einnahme der Schleiffunktion. Die mit dem Funktionswechsel einhergehende Drehrichtungsumkehr der Ringbürste führt also dazu, dass die am Stoppmittel angreifenden Borsten das Stoppmittel verstellen. Die Verstellbewegung wird dabei so lange aufrechterhalten, bis das Stoppmittel seine zur Drehrichtung gehörige Funktionsstellung einnimmt, entweder die Stopperfunktion oder die Schleiffunktion. Folgerichtig sind die beiden dem Ausleger zugeordneten Anschläge als einerseits Stopperanschlag und anderseits Schleifanschlag ausgelegt.Stopper function and another stop for taking the Schleufunktion. The rotation reversal of the ring brush, which accompanies the change in function, thus results in the bristles acting on the stop means displacing the stop means. The adjusting movement is maintained until the stop means assumes its functional position associated with the direction of rotation, either the stopper function or the grinding function. Consequently, the two stops associated with the boom are designed as a stopper stop on the one hand and a grinding stop on the other hand.
Gegenstand der Erfindung ist auch ein Rotationsbürstenwerkzeug, welches mit einem Maschinengehäuse und einer Antriebseinheit für das beschriebene Bürstenaggregat ausgerüstet ist. Außerdem ist ein Verfahren zur Bearbeitung einer Oberfläche eines Werkstoffes mit Hilfe des beschriebenen Bürstenaggregates umfasst.The invention also relates to a rotary brush tool, which is equipped with a machine housing and a drive unit for the brush unit described. In addition, a method for processing a surface of a material by means of the described brush assembly is included.
Im Ergebnis werden ein Bürstenaggregat, ein zugehöriges Rotationsbürstenwerkzeug und ein Verfahren zur Bearbeitung einer Oberfläche eines Werkstoffes mit Hilfe des Bürstenaggregates beschrieben, mit deren Hilfe eine einfache und dauerhafte Bearbeitung der Oberfläche gelingt. Dabei werden vergleichbare Rautiefen erreicht und beobachtet, wie sie auch beim (Sand-) Strahlen möglich sind und realisiert werden können. Allerdings entfallen aufwendige Antriebseinrichtungen und muss insbesondere nicht ein Strahlmittel entsorgt werden. Zugleich werden besonders hohe Standzeiten beobachtet, weil die Borsten nachgeschliffen werden können. Das alles gelingt mit Hilfe des Stoppmittels, welches eine zweifache Funktion, nämlich die beschriebene Stopperfunktion und Schleiferfunktion ausfüllt. Hierin sind die wesentlichen Vorteile zu sehen.As a result, a brush assembly, an associated rotary brush tool and a method for processing a surface of a material using the brush assembly are described, with the help of a simple and durable machining of the surface succeeds. At the same time, comparable roughness depths are achieved and observed, as they are also possible during (sand) blasting and can be realized. However, expensive drive devices are eliminated and, in particular, no blasting agent has to be disposed of. At the same time, particularly long service lives are observed because the bristles can be reground. All this is possible with the help of the stop means, which fills a double function, namely the described stopper function and wiper function. Here are the main benefits.

Man erkennt, dass sich die Borsten 5 radial im Vergleich zu einem Rotationszentrum bzw. einer Rotationsachse 6 erstrecken und im Wesentlichen senkrecht auf einer Oberfläche der Ringbürste 4, 5 bzw. einer Oberfläche des Bürstenbandes 4 aufstehen. Bei den Borsten 5 handelt es sich um U-förmige Borsten 5 aus Stahl, die in lediglich angedeutete Aufnahmebohrungen 7 im Bürstenband 4 eingesteckt und durch diese hindurch gesteckt werden (vgl.

Die Außenoberfläche 16 des Stoppmittels 4 setzt sich also aus dem Stopperbereich 16a und dem Schleifbereich 16b zusammen, die sich mehr oder minder ergänzen und meistens insgesamt die Außenoberfläche 16 des Stoppmittels 14 bilden. Tatsächlich belegt der Stopperbereich 16a in etwa 30 % bis 80 % der Außenoberfläche 16, wohingegen der Schleifbereich 16b in etwa 10 % bis 50 % der Außenoberfläche 16 des Stoppmittels 14 einnimmt. Dabei sind der Stopperbereich 16a und der Schleifbereich 16b so zueinander angeordnet, dass sie sich nicht überlappen, sondern vielmehr mit oder ohne Abstand aneinander anschließen. Als Folge hiervon wechselwirken die Borsten 5 entweder nur mit dem Stopperbereich 16a oder nur mit dem Schleifbereich 16b. Zur erstgenannten Wechselwirkung gehört die Stopperfunktion des Bürstenaggregates 3 bzw. des Rotationsbürstenwerkzeuges im Ganzen, wohingegen die letztgenannte Wechselwirkung zur Schleiffunktion korrespondiert. - Der Stopperbereich 16a und/oder der Schleifbereich 16b können an dem Stoppmittel 14 integral ausgebildet oder zusätzlich hieran angebracht werden.

Anders ausgedrückt, wird zwischen den beiden Funktionen, das heißt, zwischen der Stopperfunktion und der Schleiffunktion des Stoppmittels 14 nach Maßgabe der Drehrichtung R der Ringbürste 4, 5 und zusätzlich einer Stellposition des Stoppmittels 14 im Vergleich zum Borstenkranz 8 unterschieden. Man erkennt, dass zur Einnahme der Stopperfunktion das Stoppmittel 14 mit seinem gesamten Querschnitt bzw. seiner gesamten Außenoberfläche 16 in den Borstenkranz 8 eintaucht (vgl.
Tatsächlich taucht das Stoppmittel 14 in der Schleiffunktion lediglich mit seinem Schleifbereich 16b in den Borstenkranz 8 ein. Dadurch bewegen sich die Borsten 5 bzw. deren Borstenspitzen 5' mehr oder minder tangential an dem Stoppmittel 14 in der Schleiffunktion vorbei. Auf diese Weise werden die Borsten 5 an ihren Borstenspitzen 5' auf ihrer in Arbeitsrichtung gesehenen Rückseite schleifend bearbeitet. Das ist selbstverständlich nur beispielhaft zu verstehen, wobei die Borsten 5 grundsätzlich auch auf einer größeren Länge schleifend bearbeitet werden können.In fact, the stopping means 14 immersed in the abrasive function only with its grinding

Der Wechsel von der Stopperfunktion zur Schleiffunktion und umgekehrt erfolgt dabei jeweils mit Hilfe der angetriebenen Borsten 5. Das heißt, das Stoppmittel 14 wird von den angetriebenen Borsten 5 bzw. der angetriebenen Ringbürste 4, 5 verstellt. Diese Verstellung mit Hilfe der rotierenden Ringbürste 4, 5 respektive der gegen das Stoppmittel 14 anfahrenden Borsten 5 erfolgt so lange, bis die zugehörige Stellbewegung entweder durch den Stopperanschlag 23 oder durch den Schleifanschlag 24 begrenzt wird.The change from the stopper function to the Schleussunktion and vice versa takes place in each case with the aid of the driven bristles 5.

Die Ringbürste 4, 5 erfährt also eine Drehrichtungsumkehr. Durch die Änderung der Drehrichtung R der Ringbürste 4, 5 wird auch das Stoppmittel 14 verstellt. Denn die Borsten 5 fahren gegen das Stoppmittel 14 und verschwenken dieses im Vergleich zum Maschinengehäuse 1. Dieser Vorgang wird so lange fortgeführt, bis der entsprechende Anschlag 23, 24 eine weitere Schwenkbewegung des Stoppmittels 14 blockiert.That is, the stopping means 14 is converted by the running against
