- To turn on and off one of the three rollers is mounted radially movable on the inside of an angle lever.
- a changeover of the transport direction of the spring shaft from extension to retraction is possible here exclusively by switching the direction of rotation of the spring shaft.
- the drum can be stored in the different lengths of the spring shaft, stopped and restarted in the opposite direction.
- the device does not require reversal of the direction of rotation of the drum and spring shaft, but because of the many fits consuming in the production and has a long extension. Most importantly, to reverse thrust, the operator must move one hand around the turntable for a large pivotal path, while the weight of the cleaning machine must be picked up by the other hand.
- each a group of three rollers of which the axes of each group, distributed on the circumference of the spring shaft, are aligned with the same direction of transport, but both groups have opposite transport directions. Since in each case only one of these groups can be used simultaneously, two of the rollers of each group are each arranged on a double-armed, radially projecting angle lever, which may be formed in one or two parts.
- each group of rollers are aligned in the same direction and at an acute angle to the axis of the spring shaft ("snake"), and the thrust direction of the spring shaft can be reversed without changing the direction of rotation of the drum and spring shaft.
- the thrust reverser is carried out either by a one-piece, centrally mounted rocker with two lever arms or by two oppositely projecting levers which are pivotable about a common axis which extends transversely to the spring shaft.
- the device is arranged at the end of a guide tube for the spring shaft, so that it can not be actuated by a push handle, which is mounted on an axle fixed hollow shaft of a motor-driven drum and also for manual mounting of the machine.

- the invention is based on the surprising finding that the task can be achieved with only three rollers, of which only one is adjustable.
- 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.
- 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 provided in the direction of the drum 5 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.
- 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.
- the top right box shows the options for the direction of rotation of the motor shaft, and "R” stands for clockwise rotation and “L” for counterclockwise rotation. This switching is not mandatory for the main function of the invention, but increases the flexibility of the device.
- the terms “clockwise rotation” and “counterclockwise rotation” refer to the viewing direction of the operator, ie to the viewing direction via the drum 5 to the working tool at the end of the spring shaft 6. The same applies to the course of the winding of the spring shaft 6.
- the axis of the adjustable roller is parallel to the axis of the spring shaft 6 (again FIG. 5 ), so that no axial movement of the same takes place. If the handle tube 8 and the drum 5 are pushed together (upper illustration), the spring shaft 6 is withdrawn. If the handle tube 8 and the drum 5 are pulled apart (lower illustration), the spring shaft 6 is advanced.
- the lower left box explains the function of the adjustment knob 11: By the clockwise rotation in the direction of arrow "+” is an amplification of the contact pressure of the adjustable roller to the two stationary rollers. By turning it to the left in the direction of the arrow "-”, the contact force of the adjustable roller is reduced to the two stationary rollers. All these functions will be explained in detail below in connection with the remaining figures, in which the previous reference numerals are retained.
- the FIG. 2 shows a support tube 12 with grooves 12 a, which is arranged in the assembled state between the guide tube 7 and the handle tube 8.
- the grooves 12a are intended to intercept about entrained by the spring shaft 6 during retraction impurities to avoid binding of the handle tube 8.
- the support tube 12 terminates in a concentric circular disc 13, emanating from the three axially parallel and equidistant webs 14. These webs 14 serve to receive a high-strength gear housing 15, which has three grooves 16 on the circumference, which are formed according to cross section and spatial distribution complementary to the webs 14.
- the transmission housing 15 has a cavity 17 whose shape and purpose will be explained in more detail below.
- the switching mechanism 20 viewed from the outside inwardly, the aforementioned knob 11, an intermediate housing 21 with two recesses 21 a and 21 b, of which one 21a for the hub 11a of the knob 11 and the other 21 b for receiving a Bearing blocks 22 with the movable roller 23 is used.
- the bearing block 22 has a pin 22 a, which is surrounded by a spring assembly, not shown here.
- the contact pressure to the other two, fixedly mounted rollers 24 and 25 regulate.
- the handle tube 8 For the purpose of a linear and paraxial, but rotationally fixed displacement of the handle tube 8 with the attached or molded-in chamber 10, the latter is provided with an axially parallel bead 10a, which engages in a complementary groove 26 of the gear housing 15.
- the chamber 10 has in its cylindrical wall a recess 27, one edge region of which is accompanied by an axis-parallel row of teeth 28.

- the rollers 23, 24 and 25 are arranged with their axes A1, A2 and A3.
- the rollers 24 and 25 are spatially fixed with their inner bearing rings by screwing on not visible here oblique surfaces within the gear housing 15.
- 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.
- rollers 24 and 25 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.
- FIG. 5 shows a top view from above in the direction of the pivot axis "AS-AS”, but these figures are even more abstracted.
- the pivotable roller 23 is shown in its two end positions, by an angle " ⁇ " of, for example, about 20 degrees, in each case about the pivot axis "AS-AS", starting from the central position FIG. 5 , twisted ..

Abstract
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 und mit einem Getriebegehäuse, in dem mehrere, radial auf die Federwelle einwirkende Walzen mit Achsen angeordnet sind, die mit radialen Abständen unter Winkeln zur Achse der Federwelle ausgerichtet sind.The invention relates to a hand-held cleaning device for cleaning pipelines by means of a spring shaft, equipped with a motor, a drum for receiving and outputting the spring shaft and a transmission housing in which a plurality of radially acting on the spring shaft rollers are arranged with axes, the are aligned with radial distances at angles to the axis of the spring shaft.
Die Notwendigkeit von Rohrreinigungen wächst mit der Wahrscheinlichkeit des Zusetzens von Leitungen. Hierfür gibt es eine Vielzahl von Ursachen, z.B. Verstopfungen durch Papier wie Toilettenpapier, Taschentücher, Servietten u. dgl., versehentlich entsorgte Windeln und Waschlappen, Ablagerungen durch Kalkbildung, mitgeführte Bindemittel, Farbreste, Küchenabfälle, durch Verbindungs- und Bruchstellen eingedrungene Pflanzenwurzeln, von Regenwasser mitgeführte Verunreinigungen, Querschnittsänderungen und Verzweigungen der Rohrleitung, etc. Dabei können sich die Wirkungen auch additiv und kumulativ bis zur dichten Verstopfung verstärken. Besonders gefährlich sind z.B. durch Fugen und Kittstellen eingedrungene Pflanzenwurzeln, an denen so ziemlich alles hängen bleibt, was nicht ausgesprochen dünnflüssig ist. Einige Pflanzenwurzeln arbeiten sich geradezu bis zu Wasserstellen durch.The need for pipe cleaning increases with the likelihood of clogging pipes. There are a variety of causes, such as blockages through paper such as toilet paper, handkerchiefs, napkins u. Like., Disposed accidentally diapers and washcloths, deposits due to calcification, entrained binders, paint residues, kitchen waste, penetrated by connecting and breaking points plant roots, rainwater entrained impurities, cross-sectional changes and branching of the pipeline, etc. The effects may also be additive and cumulative reinforce until dense constipation. Particularly dangerous are, for example, through joints and putties penetrated plant roots, where just about everything gets stuck, which is not very thin. Some plant roots work their way through to watering holes.
Entsprechend vielfältig sind auch die Reinigungswerkzeuge, die über entsprechende Kupplungen an die Federwellen angesetzt werden können. Dazu gehören Schneidköpfe, Keulenbohrer, Rückholbohrer, Trichterbohrer, Kreuzblattbohrer, Schaufelkopfbohrer, Hartmetallbohrköpfe, Sägezahn-Schneidköpfe, Wurzelschneider, Gabelschneidköpfe, Fettaustreiber, Ketten-Schleuderköpfe mit und ohne Spikes, Hartmetallbohrköpfe etc.Accordingly diverse are the cleaning tools that can be attached to the spring shafts via appropriate couplings. These include cutting heads, club drills, return drills, hopper drills, crosshead drills, blade head drills, carbide drills, sawtooth cutting heads, root cutters, fork heads, grease drippers, chain spinner heads with and without spikes, carbide heads, etc.
Entsprechend vielfältig sind auch die notwendigen Handhabungen: Schneller oder langsamer kontinuierlicher Vorschub und Rückzug der Reinigungswerkzeuge, Bohren, Schaben oder Sägen "auf der Stelle" oder oszillierend mit Hin- und Herbewegungen der Werkzeuge gegen hartnäkkige Verstopfungen und beim Rückholen von Teilportionen der Verstopfung. Hierbei darf z.B. nicht die Torsionsfestigkeit der Federwelle überschritten werden. Ferner muss bei Handmaschinen eine zuverlässige Haltung ohne Förderung von Ermüdungen möglich sein, insbesondere zentrisch gegenüber Einführungsöffnungen in die Rohrleitung.The necessary manipulations are correspondingly varied: rapid or slow continuous advancement and retraction of the cleaning tools, drilling, scraping or sawing "on the spot" or oscillating with reciprocating movements of the tools against obstinate blockages and when retrieving partial portions of the blockage. In this case, e.g. not the torsional strength of the spring shaft are exceeded. Furthermore, in hand machines, a reliable attitude without promotion of fatigue must be possible, especially centric with respect to introduction openings in the pipeline.
Auf dem Gebiet der Rohrreinigungsmaschinen hat man ursprünglich aus Stahldraht gewendelte Federwellen verwendet - im Branchenjargon auch als "Reinigungsspiralen" bezeichnet - bei denen die einzelnen Windungen einen Abstand voneinander aufwiesen. Damit war es möglich, dass sich die Federwellen durch Gewindewirkung in den Rohrleitungen lediglich durch ihr Drehmoment "fortschraubten" und nach Umkehr der Drehrichtung auch wieder zurückkehrten. Dafür reichten auch schon radial wirkende Reibungskupplungen in kofferförmigen tragbaren oder fahrbaren Antriebsmaschinen aus.In the field of pipe cleaning machines, helical shafts were originally used in steel wire - also known as "cleaning spirals" in industry jargon - in which the individual windings were at a distance from each other. Thus, it was possible that the spring waves "screwed" by thread action in the pipes only by their torque and also returned after reversing the direction of rotation. For this reason, even radially acting friction clutches in suitcase-shaped portable or mobile drive machines were sufficient.
Man hat auch bereits formschlüssig arbeitende Antriebseinheiten verwendet, bei denen Haken, Krallen, Kugeln oder andere Vorsprünge in die Zwischenräume zwischen den Windungen eingriffen. In den vorgenannten Fällen, war allerings eine Umkehr der Transportrichtung der Federwelle nur durch eine Umkehr ihres Drehsinns möglich. Bei Maschinen mit einer Trommel für die Aufnahme der Federwelle wäre dies allerdings mit Nachteilen verbunden: Die Masse von Trommel und Federwelle erzeugt beim Abbremsen und wieder Anfahren erhebliche Trägheitsmomente, deren Abbau zeitraubend ist und die die Bedienungsperson belasten.It has also been used positively working drive units in which hooks, claws, balls or other projections intervened in the spaces between the turns. In the above cases, however, a reversal of the transport direction of the spring shaft was only possible by reversing its direction of rotation. In machines with a drum for receiving the spring shaft, however, this would be associated with disadvantages: The mass of drum and spring shaft generated during braking and restarting considerable moment of inertia, the Dismantling is time consuming and burden the operator.
Mit dem übergang auf Federwellen ohne nennenswerten Windungsabstand ist man daher auf Antriebe mit radial angepressten Walzen übergegangen, deren Aussenflächen zumindest im wesentlichen Zylinderflächen sind. Sobald die Achsen solcher Walzen - entsprechend radial versetzt - unter einem spitzen Winkel zur Achse der Federwelle stehen, werden durch Reibungskräfte und entsprechende Kräfteparallelogramme zur Federwelle achsparallel verlaufende Transportkräfte erzeugt, die je nach der Raumlage der Winkelstellung zu einem unterschiedlich starken Vorschub oder Rückzug der Federwelle führen. Je nach der Grösse der radialen Anpresskräfte der Walzen lassen sich beträchtliche Vorschubkräfte erzeugen.With the transition to spring waves without significant winding spacing is therefore transferred to drives with radially pressed rollers whose outer surfaces are at least substantially cylindrical surfaces. As soon as the axes of such rollers - correspondingly offset radially - are at an acute angle to the axis of the spring shaft, friction forces and corresponding force parallelograms to the spring shaft axially parallel transport forces are generated, which lead depending on the spatial position of the angular position to a different strong feed or retraction of the spring shaft , Depending on the size of the radial contact forces of the rollers, considerable feed forces can be generated.
Sofern die Achsen der Walzen parallel zur Achse der Federwelle stehen, erfolgt ein Stillstand der Federwelle in ihrer Achsrichtung, allerdings unter Fortsetzung der Rotation, die in gleichem Drehsinne (!) durch die Trommel und ihren Antrieb bestimmt wird. Das ermöglicht blitzschnelle Umschaltungen der Drehrichtung ohne nenneswerte äussere Kraftfreisetzungen. Insbesondere wird dadurch auch der Vorschub oder Rückzug der Federwelle von der Steigung der Windungen der Federwelle entkoppelt. Dies ist auch die kinematische Grundlage der Erfindung.If the axes of the rollers are parallel to the axis of the spring shaft, there is a standstill of the spring shaft in its axial direction, but with continued rotation, which is determined in the same sense of rotation (!) By the drum and its drive. This enables lightning-fast switching of the direction of rotation without any notable external release of force. In particular, the feed or retraction of the spring shaft is thereby decoupled from the pitch of the turns of the spring shaft. This is also the kinematic basis of the invention.

Andernfalls muss die Federwelle von Hand wieder in die Trommel eingeschoben werden. Eine Weiterentwicklung, bei der die Rastkörper durch leichter auswechselbare Blattfedern ersetzt sind und der Rückzug der Federwelledurch Drehrichtungsumkehr des Motors bewirkt werden kann, ist in der

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, ein Reinigungsgerät der eingangs beschriebenen Gattung anzugeben, das mit einer geringeren Zahl von Präzisionsteilen auskommt, eine dosierbare Transportgeschwindigkeit der Federwelle in beiden Achsrichtungen sowie eine schnelle Umschaltung der Transportrichtung der Federwelle ohne Umkehr der Drehrichtung der Trommel erlaubt, ohne dass hierbei eine Verlagerung einer Hand der Bedienungsperson an einen abstehenden beweglichen Hebel erfolgen müsste, wobei gleichzeitig die Ermüdungsgefahr für die Bedienungsperson trotz der Handbedienung verringert wird.The invention is based on the object to provide a cleaning device of the type described above, which manages with a smaller number of precision parts, a metered transport speed of the spring shaft in both axial directions and a fast switching of the transport direction of the spring shaft without reversing the direction of rotation of the drum allowed, without that in this case a displacement of a hand of the operator would have to be done on a protruding movable lever, while reducing the risk of fatigue for the operator despite the manual operation is reduced.
Die vorstehenden Aufgabe wird erfindungsgemäss gelöst durch:
- a) eine einzige Gruppe von drei auf den Umfang der Federwelle verteilten Walzen, von denen die Achsen zweier Walzen lagefest so ausgerichtet sind, dass diese mit entgegengesetzten Transportkräften auf die Federwelle einwirken, und dass die Achse der dritten Walze in ihrer Raumlage derart verstellbar ist, dass die Transportkraft der verstellbaren Walze wahlweise die Transportkraft der einen lagefesten Walze oder der anderen lagefesten Walze unterstützt, und
- b) durch ein die Federwelle verschiebbar umschliessendes Griffrohr mit Mitteln für die Verstellung der dritten Walze in beide Transportrichtungen der Federwelle.
- a) a single group of three rollers distributed on the circumference of the spring shaft, of which the axes of two rollers are positionally aligned so that they act with opposite transport forces on the spring shaft, and that the axis of the third roller is adjustable in its spatial position, that the transport power of adjustable roller supports either the transport force of a position-fixed roller or the other positionally stable roller, and
- b) by a spring shaft slidably enclosing handle tube with means for adjusting the third roller in both directions of transport of the spring shaft.
Durch die Erfindung wurd die genannte Aufgabe in vollem Umfange gelöst, und es wird ein Reinigungsgerät der eingangs beschriebenen Gattung dadurch verbessert, dass es mit einer geringeren Zahl von Präzisionsteilen auskommt, eine dosierbare Transportgeschwindigkeit der FederWelle in beiden Achsrichtungen sowie eine schnelle Umschaltung der Transportrichtung der Federwelle ohne Umkehr der Drehrichtung der Trommel ermöglicht, ohne dass hierbei eine Verlagerung einer Hand der Bedienungsperson an einen abstehenden beweglichen Hebel erfolgen müsste, wobei gleichzeitig die Ermüdungsgefahr für die Bedienungsperson trotz der Handbedienung verringert wird. Der Erfindung liegt die überraschende Feststellung zugrunde, das die Aufgabe mit nur drei Walzen gelöst werden kann, von denen nur eine verstellbar ist.By the invention wurd said object was fully achieved, and it is a cleaning device of the type described above improved by the fact that it requires a smaller number of precision parts, a metered transport speed of the spring shaft in both axial directions and a fast switching of the transport direction of the spring shaft Without reversing the direction of rotation of the drum allows, without this a displacement of a hand of the operator would have to be done on a protruding movable lever, while reducing the risk of fatigue for the operator despite the manual operation is reduced. The invention is based on the surprising finding that the task can be achieved with only three rollers, of which only one is adjustable.

In dem Kasten darunter sind die Einstellmöglichkeiten mittels des Griffrohres 8 dargestellt. Die linke Kastenhälfte erläutert die Vorgänge für eine Rechtsdrehung "R" der Federwelle 6. In der Mitte steht das Griffrohr 8 in einer neutralen Stellung, angedeutet durch eine "0". Die Achse der verstellbaren Walze steht hierbei parallel zur Achse der Federwelle 6 (
Der linke untere Kasten erläutert die Funktion des Einstellknopfes 11: Durch dessen Rechtsdrehung in Pfeilrichtung "+" erfolgt eine Verstärkung der Anpresskraft der verstellbaren Walze an die beiden stationären Walzen. Durch dessen Linksdrehung in Pfeilrichtung "-" erfolgt eine Verringerung der Anpresskraft der verstellbaren Walze an die beiden stationären Walzen. Alle diese Funktionen werden nachstehend im Zusammenhang mit den übrigen Figuren nach eingehend erläutert, in denen die bisherigen Bezugszeichen beibehalten werden.The lower left box explains the function of the adjustment knob 11: By the clockwise rotation in the direction of arrow "+" is an amplification of the contact pressure of the adjustable roller to the two stationary rollers. By turning it to the left in the direction of the arrow "-", the contact force of the adjustable roller is reduced to the two stationary rollers. All these functions will be explained in detail below in connection with the remaining figures, in which the previous reference numerals are retained.
