Description

Die Erfindung betrifft ein Handgeführtes Reinigungsgerät für die Reinigung von Rohrleitungen mittels einer Federwelle, ausgestattet mit einem Motor, einer Trommel für die Aufnahme und Ausgabe der Federwelle, mit einer Kammer, in der mehrere, radial auf die Federwelle einwirkende Walzen mit Achsen angeordnet sind, die mit radialen Abständen von der Achse der Federwelle angeordnet sind, wobei eine der Walzen in einem Lagerbock gelagert ist, dessen radialer Abstand von der Achse der Federwelle durch einen Einstellknopf veränderbar ist.The invention relates to a hand-held cleaning device for cleaning pipes by means of a spring shaft, equipped with a motor, a drum for receiving and outputting the spring shaft, with a chamber in which a plurality of radially acting on the spring shaft rollers are arranged with axes, the are arranged at radial distances from the axis of the spring shaft, wherein one of the rollers is mounted in a bearing block, the radial distance from the axis of the spring shaft by a knob is variable.

Der Stand der Technik:The state of the art:

Durch die DE 10 2008 015 532 A1 ist ein Reinigungsgerät mit einer Federwelle bekannt, deren Längsbewegung über drei Walzen bewirkt wird, die mit radialen und axialen Kraftkomponenten auf die Federwelle einwirken. Von den Walzen sind zwei in Bezug auf ihre sich schneidenden Achsen unter einem spitzen Winkel ortsfest zueinander gelagert, und die Achse der dritten Walze ist derart um eine radiale Achse schwenkbar, dass diese dritte Walze alternativ mit einer der beiden anderen Walzen in eine Wirkverbindung gebracht werden kann. Die Schwenkbewegung der dritten Walze erfogt durch ein Griffrohr, das über eine Zahnreihe auf einen Zahnsektor am Lagerbock der dritte Walze einwirkt. Soweit dort ein Einstellknopf für die Einstellung der radialen Anpresskraft der dritten Walze beschrieben ist, wirkt dieser zwar über ein elastisches Element auf den Lagerbock der dritten Walze ein, ist aber drehfest mit seiner Einstellwelle verbunden, so dass bei einer Fehlbedienung des Einstellknopfes, z.B. mit einer Zange, eine überlastung und Verformung des Walzensystems, aber auch der Federwelle, erfolgen kann, was zum Ausfall des Geräts führt. Zum Stand der Technik gehören aber auch andere Reinigungsgeräte, bei denen drei Walzen mit gleichen relativen Winkelstellungen um die Systemachse und die Achse der Federwelle angeordnet sind:

  • Durch die US 2002/0083538 A1 ist es beispielsweise bekannt, den Transportweg einer Federwelle, der von eine Vorratstrommel ausgeht, mit einem zylindrischen Gehäuse zu umgeben, von dessen Umfang in äquidistanter Verteilung nach innen drei radiale Halterungen ausgehen, in denen Lagerböcke für Walzen angeordnet sind. An einer Stelle des Umfangs befindet sich ein Rohrstutzen mit einem Innengewinde, in das eine Hohlwelle mit einem Aussengewinde eingeschraubt ist. Diese Hohlwelle besitzt ausserdem ein Innengewinde für das Einschrauben eines Einstellknopfes, mit dem die Winkelstellung und die radiale Lage der zugehörigen Walze gegenüber der Achse der Federwelle einstellbar ist. Der radiale Hub der Rollenanordnung 155 ist durch einen Stift 180 begrenzt, der gemäss den Figuren 4 und 4A an eine Blattfeder 205 anstösst. Dadurch wid die Einstellung bei dünnen Federwellen unwirksam, und bei einer hohen manuellen Einstellkraft am Gewindezapfen 215 kann die Blattfeder 205 brechen. Mittel für eine Begrenzung der Rotationskraft des Einstellknopfes sind jedoch nicht offenbart und auch nicht vorgesehen.
By the DE 10 2008 015 532 A1 is a cleaning device with a spring shaft known, the longitudinal movement is effected via three rollers, which act with radial and axial force components on the spring shaft. Of the rollers, two are fixed with respect to each other at an acute angle with respect to their intersecting axes, and the axis of the third roller is pivotable about a radial axis such that this third roller is alternatively brought into operative connection with one of the other two rollers can. The pivoting movement of the third roller erfogt by a handle tube, the teeth on a row on a dental sector acts on the bearing block of the third roller. As far as there is described a knob for setting the radial contact force of the third roller, this acts via an elastic element on the bearing block of the third roller, but is rotatably connected to its setting, so that in case of incorrect operation of the knob, eg with a Pliers, overloading and deformation of the roller system, but also the spring shaft, can be done, resulting in failure of the device. The prior art but also include other cleaning equipment, in which three rollers are arranged with the same relative angular positions about the system axis and the axis of the spring shaft:
  • By the US 2002/0083538 A1 For example, it is known to surround the transport of a spring shaft, which emanates from a storage drum, with a cylindrical housing, extending from the circumference in equidistant distribution inwardly three radial brackets, in which bearing blocks are arranged for rollers. At one point of the circumference is a pipe socket with an internal thread into which a hollow shaft with an external thread is screwed. This hollow shaft also has an internal thread for screwing a knob, with which the angular position and the radial position of the associated roller relative to the axis of the spring shaft is adjustable. The radial stroke of the roller assembly 155 is limited by a pin 180 which abuts a leaf spring 205 according to FIGS. 4 and 4A. As a result, the setting is ineffective with thin spring shafts, and at a high manual adjusting force on the threaded stem 215, the leaf spring 205 may break. However, means for limiting the rotational force of the adjusting knob are not disclosed and not provided.

Die Aufgabe:The task:

Der Erfindung liegt daher die Aufgabe zugrunde, ein Reinigungsgerät der eingangs beschriebenen Gattung anzugeben, durch das eine überlastung des Antriebssystems durch fehlerhafte Einstellung der radialen Kräfte und/oder überschreitung von Masstoleranzen ausgeschlossen ist. Diese Aufgabe kann durch die US 2002/0083538 A1 nicht gelöst werden.The invention is therefore based on the object to provide a cleaning device of the type described above, is excluded by the overloading of the drive system by incorrect adjustment of the radial forces and / or exceeding of dimensional tolerances. This task can be done by the US 2002/0083538 A1 not be solved.

Die Lösung der Aufgabe:The solution of the task:

Diese ist dadurch kennzeichnet, dass zwischen dem Einstellknopf und dem Lagerbock eine Vorrichtung zur Drehmomentenbegrenzung angeordnet ist, mittels welcher die Radialkräfte der Walze auf vorgebbare Maximalwerte begrenzbar sind.This is characterized in that between the adjusting knob and the bearing block, a device for torque limiting is arranged, by means of which the radial forces of the roller can be limited to predetermined maximum values.

Es ist im Zuge weiterer Ausgestaltungen der Erfindung besonders vorteilhaft, wenn - entweder einzeln, oder in Kombination:

  • * der Einstellknopf einen Hohlraum umschliesst, in den eine Welle hineinragt, die von einem Stützring umgeben ist, auf dem sich ein Reibungskörper abstützt, dessen gegenüberliegende Seite an einer Innenfläche des Einstellknopfes anliegt, und wenn sich die Welle drehbar auf einem Spreizring abstützt,
  • * der Reibungskörper aus mindestens zwei Tellerfedern besteht, die sich in gespreiztem Zustand berühren,
  • * die Welle in axialer Richtung abgedichtet in dem Einstellknopf geführt ist,

  • * die Welle eine koaxiale Ausnehmung aufweist in der ein zylindrischer Zapfen geführt ist, der von dem Lagerbock für die verstellbare Walze absteht,
  • * zwischen der Welle und dem Lagerbock ein elastisches Element zur Einstellung der Anpresskraft der Walze an die Federwelle angeordnet ist,
  • * das elastisches Element den Zapfen umgibt,
  • * der Einstellknopf auf seiner Aussenseite mit einer griffgünstigen Profilierung versehen ist, und/oder, wenn
  • * das Reinigungsgerät eine einzige Gruppe von drei auf den Umfang der Federwelle verteilten Walzen aufweist, von denen die Achsen zweier Walzen lagefest so ausgerichtet sind, dass diese mit entgegengesetzten Transportkräften auf die Federwelle einwirken, und wenn die Achse der dritten Walze in ihrer Raumlage derart verstellbar ist, dass die Transportkraft der verstellbaren Walze wahlweise die Transportkraft entweder der einen lagefesten Walze oder der anderen lagefesten Walze unterstützt.
It is particularly advantageous in the course of further embodiments of the invention if, either individually or in combination:
  • the adjustment knob encloses a cavity into which a shaft surrounded by a support ring on which a friction body is supported, whose opposite side abuts an inner surface of the adjustment knob, and when the shaft is rotatably supported on a spreader ring,
  • * The friction body consists of at least two disc springs, which touch in a spread state,
  • * the shaft is guided sealed in the axial direction in the adjusting knob,
  • the shaft has in coaxial arrangement an external thread, with which it is guided in an internal thread, which is located in a pipe socket, which projects in the radial direction from the chamber,
  • * The shaft has a coaxial recess in which a cylindrical pin is projecting, which protrudes from the bearing block for the adjustable roller,
  • * between the shaft and the bearing block an elastic element for adjusting the contact force of the roller is arranged on the spring shaft,
  • * the elastic element surrounds the pin,
  • * The knob is provided on its outside with a handy profiling, and / or, if
  • * The cleaning device has a single group of three distributed on the circumference of the spring shaft rollers, of which the axes of two rollers are positionally aligned so that they act with opposite transport forces on the spring shaft, and if the axis of the third roller in its spatial position so adjustable is that the transport force of the adjustable roller optionally supports the transport force of either a positionally fixed roller or the other positionally stable roller.

In Figur 1 ist ein komplettes Reinigungsgerät 1 dargestellt, zu dem ein Motor 2 mit einem Handgriff 3 und einem Schalter 4 gehören, wie dies auch von Handbohrmaschinen her bekannt ist. An den Motor ist eine drehbare Trommel 5 für die Aufnahme einer Federwelle 6 angesetzt. Die Trommel 5 besitzt ein fest angesetztes Führungsrohr 7 (Figur 2), das koaxial von einem Griffrohr 8 umgeben ist, das in Richtung auf die Trommel 5 mit einem trichterförmigen Handschutz 9 versehen ist. Dieser Handschutz 9 überdeckt teilweise die gleichfalls trichterförmige Stirnwand 5a der Trommel 5. Das Griffrohr 8 geht in eine zylindrische Kammer 10 über, in der der komplette Verstellmechanismus für die Bewegung der Federwelle 6 untergebracht ist. Ein Einstellknopf 11 dient zum Einstellen einer Anpresskraft der verstellbaren Walze an die beiden ortsfesten Walzen, was nachstehend noch näher erläutert wird. In Figur 1 ist jeweils nur das Ende dieser Federwelle 6 gezeigt, und an deren örtlicher Verdickung ist zu erkennen, dass dieses Ende bereits eine Werkzeugfunktion besitzt.In FIG. 1 a complete cleaning device 1 is shown, to which a motor 2 with a handle 3 and a switch 4 belong, as is also known from hand drills ago. To the motor, a rotatable drum 5 is attached for receiving a spring shaft 6. The drum 5 has a fixed attached guide tube 7 ( FIG. 2 ), which is coaxially surrounded by a handle tube 8, which is in the direction of the drum 5 is provided with a funnel-shaped hand guard 9. This hand guard 9 partially covers the likewise funnel-shaped end wall 5a of the drum 5. The handle tube 8 merges into a cylindrical chamber 10, in which the complete adjusting mechanism for the movement of the spring shaft 6 is housed. An adjusting knob 11 is used to set a pressing force of the adjustable roller to the two stationary rollers, which will be explained in more detail below. In FIG. 1 in each case only the end of this spring shaft 6 is shown, and at the local thickening it can be seen that this end already has a tool function.

Die Achse der verstellbaren Walze 12 (in Figur 2, oben) steht hierbei zunächst parallel zur Achse der Federwelle 6, so dass keine Axialbewegung derselben erfolgt. Werden das Griffrohr 8 und die Trommel 5 zusammengeschoben, so erfolgt ein Rückzug der Federwelle 6. Werden das Griffrohr 8 und die Trommel 5 auseinander gezogen, so erfolgt ein Vorschub der Federwelle 6.The axis of the adjustable roller 12 (in FIG. 2 , above) is in this case initially parallel to the axis of the spring shaft 6, so that no axial movement thereof takes place. If the handle tube 8 and the drum 5 are pushed together, the spring shaft 6 is withdrawn. If the handle tube 8 and the drum 5 are pulled apart, the spring shaft 6 is advanced.

Der untere Kasten in Figur 1 erläutert die Funktion des Einstellknopfes 11: Durch dessen Rechtsdrehung in Pfeilrichtung "+" erfolgt eine Verstärkung der Anpresskraft der verstellbaren Walze an die beiden anderen Walzen. Durch dessen Linksdrehung in Pfeilrichtung "-" erfolgt eine Verringerung der Anpresskraft der verstellbaren Walze 12 an die beiden anderen Walzen. Alle diese Funktionen werden nachstehend im Zusammenhang mit der Figur 3 noch eingehend erläutert, in der die bisherigen Bezugszeichen beibehalten werden.The lower box in FIG. 1 explains the function of the adjustment knob 11: By the clockwise rotation in the direction of arrow "+" is an amplification of the contact force of the adjustable roller to the other two rollers. By turning it to the left in the direction of the arrow "-", the contact force of the adjustable roller 12 is reduced to the other two rollers. All of these features are discussed below in connection with the FIG. 3 to be explained in detail, in which the previous reference numerals are retained.

Gemäss Figur 2 enthält die Kammer 10 drei Walzen 12, 13 und 14, von denen die Walze 12 um die radiale Achse A-A verdrehtbar ist. Zu diesem Zweck besitzt die Kammer 10 eine achsparallel Zahnleiste 15, in die ein Zahnsektor 16a eines Lagerbocks 16 eingreift, in dem die Walze 12 gelagert ist. Von dem Lagerbock 16 steht in Richtung der Achse A-A ein zylindrischer Zapfen 17 ab, der von einem elastischen Element 18 umgeben ist, das aus einem Stapel gespreizter Tellerfedern besteht. Dadurch lässt sich mittels des Einstellknopfes 11 die Anpresskraft an die beiden anderen, ortfest montierten Walzen 13 und 14 regulieren.According to FIG. 2 The chamber 10 includes three rollers 12, 13 and 14, of which the roller 12 is rotatable about the radial axis AA. For this purpose, the chamber 10 has an axially parallel rack 15, in which a tooth sector 16a of a bearing block 16 engages, in which the roller 12 is mounted. From the bearing block 16 is in the direction of the axis AA from a cylindrical pin 17, which is surrounded by an elastic member 18 which consists of a stack of spread disc springs. As a result, by means of the adjusting knob 11, the contact pressure to the other two, fixedly mounted rollers 13 and 14 regulate.

Die Figur 2 zeigt ferner eine Längsachse "AL", die auch die Systemachse und die Achse der Federwelle 6 ist und die hier die Blickrichtung bestimmt. Auf dem Umfang der Federwelle 6 sind die Walzen 12, 13 und 14 mit ihren Achsen A1, A2 und A3 angeordnet. Die Walzen 13 und 14 sind mit ihren inneren Lagerringen durch Verschrauben auf hier nicht sichtbaren Schrägflächen räumlich fixiert. Die Raumlage ist dabei so gewählt worden, dass deren Achsen A2 und A3 sich in einem virtuellen Punkt "P" schneiden, gleichzeitig aber schräg und tangential zu einer virtuellen Zylinderfläche verlaufen, die die Achse "AL" mit entsprechendem Abstand konzentrisch umgibt. Dadurch sind die Walzen 13 und 14 spiegelsymmetrisch zueinander angeordnet, und drehen sich, angetrieben durch die Berührung mit der Federwelle 6, in hierzu entgegengesetzten Drehrichtungen. Hierbei entstehen Reibungskräfte, von denen jeweils eine Komponente parallel zur Achse "AL verläuft. Diese Komponenten verlaufen in entgegengesetzten Richtungen, erzeugen also aufgrund eines Kräfte-Gleichgewichts keinerlei axiale Bewegungen der Federwelle 6.The FIG. 2 further shows a longitudinal axis "AL", which is also the system axis and the axis of the spring shaft 6 and which determines the viewing direction here. On the circumference of the spring shaft 6, the rollers 12, 13 and 14 are arranged with their axes A1, A2 and A3. The rollers 13 and 14 are spatially fixed with their inner bearing rings by screwing on not visible here inclined surfaces. The spatial position has been chosen so that their axes A2 and A3 intersect in a virtual point "P", but at the same time run obliquely and tangentially to a virtual cylindrical surface, which concentrically surrounds the axis "AL" with a corresponding distance. As a result, the rollers 13 and 14 are arranged mirror-symmetrically to each other, and rotate, driven by the contact with the spring shaft 6, in opposite directions of rotation. This results in frictional forces, one component of which runs parallel to the axis "AL." These components extend in opposite directions, and thus do not generate any axial movements of the spring shaft 6 due to a force equilibrium.

Das System besitzt nun die bereits erwähnte Achse A-A, die eine Steuerachse ist und die auch durch den Zapfen 17 des Lagerbocks 16 verläuft und auch die Achse "A1" der Walze 12 schneidet. In der dargestellten Position verlaufen die Achsen "AL" und "A1" parallel zueinander, so dass das Kräfte-Gleichewicht nicht gestört wird. Dieser Zustand ändert sich jedoch, sobald der Lagerbock 16 mit der Walze 12 um die Achse "A-A" geschwenkt wird. Mit zunehmendem Schwenkwinkel unterstützt die Walze 12 entweder die Transportrichtung und -wirkung der Walze 13 oder der Walze 14. Dies gilt für beide Schwenkrichtungen aus der Position der Figur 2 heraus. Diese Unterstützung wird grösstmöglich, sobald die Drehrichtungen zweier Walzen, entweder 12+13 oder 12+14, übereinstimmen. Die Schubwirkung der jeweils anderen Walze wird dadurch im Ergebnis ausser Kraft gesetzt bzw. überwunden. Dieser Effekt hat sich durch Versuche überraschend bestätigt und führt in Verbindung mit dem Griffrohr 8 ohne Umgreifen der einen Hand zu einer äusserst einfachen, kurzen, kostengünstigen und zuverlässigen Bau- und Betriebsweise mit extrem rasch zu bewirkender Schubumkehr der Federwelle 6 und ohne weit abstehende Bauteile.The system now has the aforementioned axis AA, which is a control axis and which also passes through the pin 17 of the bearing block 16 and also the axis "A1" of the roller 12 intersects. In the position shown, the axes "AL" and "A1" run parallel to each other, so that the balance of forces is not disturbed. However, this state changes as soon as the bearing block 16 with the roller 12 is pivoted about the axis "AA". With increasing pivot angle, the roller 12 supports either the transport direction and action of the roller 13 or the roller 14. This is true for both pivoting directions from the position of FIG. 2 out. This support is maximized as soon as the directions of rotation of two rolls, either 12 + 13 or 12 + 14, coincide. The thrust effect of the other roller is thereby overridden or overcome in the result. This effect has been surprisingly confirmed by experiments and leads in connection with the handle tube 8 without encompassing one hand to an extremely simple, short, inexpensive and reliable construction and operation with extremely quickly to be effected thrust reversal of the spring shaft 6 and without far-protruding components.

Wie aus den Figuren 2 und 3 hervorgeht, ist der zylindrische Zapfen 17 mit einem elastischen Element 18 von einer Welle 19 umgeben, die ein Aussengewinde 20 besitzt. Mit diesem ist sie in einem Rohrstutzen 21 geführt, der ein komplementäres Innengewinde 22 besitzt. Der Rohrstutzen 21 verläuft radial zur Kammer 10. Die Welle 19 besitzt eine abgestufte konzentrische Ausnehmung 23, die mit ihrem weitesten Durchmesser das elastische Element 18 umschliesst. In einem engeren Längenabschnitt der Welle 19 ist der Zapfen 17 von einer Ringnut 24 mit einem elastischen Ring 25 umgeben, der eine Trennung von Zapfen 17 und Welle 19 zumindest erschwert.Like from the Figures 2 and 3 As can be seen, the cylindrical pin 17 is surrounded by an elastic element 18 by a shaft 19 which has an external thread 20. With this it is guided in a pipe socket 21, which has a complementary internal thread 22. The pipe socket 21 extends radially to the chamber 10. The shaft 19 has a stepped concentric recess 23 which encloses the elastic element 18 with its widest diameter. In a narrower longitudinal section of the shaft 19, the pin 17 is surrounded by an annular groove 24 with an elastic ring 25 which at least makes it difficult to separate pin 17 and shaft 19.

Hier setzt nun der Kern der Erfindung ein: Die Welle 19 ist mit kurzem Abstand von ihrem Ende verdrehfest von einem Stützring 26 umgeben, auf dem ein Reibungskörper 27 aufliegt. Dieser besteht aus mindestens zwei konischen Tellerfedern 27a, auf denen sich der Einstellknopf 11 abstützt, der zu diesem Zweck einen Hohlraum 11a besitz, der von einem Greifzylinder 11 b umgeben ist, der auf seiner Aussenseite eine Profilierung 11 c besitzt. Durch den Reibungskörper 27 wird eine genau einstellbare Reibungsbremse, eine sogenannte Rutschkupplung, gebildet, die im Ergebnis eine Drehmomentenbegrenzung für den Einstellknopf 11 darstellt. Eine unbeabsichtige Trennung von Einstellknopf 11 und Welle 19 wird durch einen Spreizring 28 verhindert, und eine Abdichtung gegen das Eindringen von Schmutz wird durch einen Dichtungsring 29 erzielt.Here is the core of the invention: The shaft 19 is rotationally surrounded by a short distance from its end by a support ring 26 on which a friction body 27 rests. This consists of at least two conical disc springs 27a, on which the adjusting knob 11 is supported, which has a cavity 11a for this purpose, which is surrounded by a gripping cylinder 11 b, which has a profiling 11 c on its outer side. By the friction body 27 a precisely adjustable friction brake, a so-called slip clutch is formed, which represents a torque limit for the adjustment knob 11 as a result. An inadvertent separation of the knob 11 and shaft 19 is prevented by a spreader ring 28, and a seal against the ingress of dirt is achieved by a sealing ring 29.

Es ist dabei zusätzlich möglich, die Federwelle zu Zwecken einer Umschaltung mit einem verschiebbaren Griffrohr zu umgeben, und ferner mit Mitteln für die Verstellung mindestens einer der Walzen in beide Transportrichtungen der Federwelle,It is additionally possible to surround the spring shaft for purposes of switching with a displaceable handle tube, and also with means for the adjustment of at least one of the rollers in both transport directions of the spring shaft,
