Description

Die Erfindung betrifft ein Handwerkzeug entsprechend dem Oberbegriff der Ansprüche 1 und 2.The invention relates to a hand tool according to the preamble of claims 1 and 2.

Ein derartiges Handwerkzeug ist durch die US-A-3 550 815 bekannt. Ein nach diesem Patent ausgebildetes Handwerkzeug ist zum Fördern von fließfähigem Stoff durch eine Düse hindurch mit einem Antrieb versehen. Der Antrieb ist ein elektrischer Motor, der über ein Getriebe einen Kolben in einem Zylinder und damit den im Preßzylinder befindlichen fließfähigen Stoff zur Düse bewegt. Unmittelbar vor der Düse ist eine Rolle angeordnet, die beim Aufsetzen auf eine Unterlage, z.B. auf ein zu bearbeitendes Werkstück, zum Verteilen des Stoffes dient.Such a hand tool is known from US-A-3 550 815. A hand tool designed according to this patent is provided with a drive for conveying flowable material through a nozzle. The drive is an electric motor that moves a piston in a cylinder and thus the flowable material in the press cylinder to the nozzle via a gear. Immediately in front of the nozzle there is a roller which, when placed on a support, e.g. on a workpiece to be machined to distribute the material.

Vor allem bei für den Bearbeiter unbequemen Arbeitspositionen und bei zu bearbeitenden Flächen mit wechselnder Neigung oder mit Unebenheiten ist es mit diesem Handwerkzeug schwierig, einen gleichmäßigen Auftrag des Stoffs über die Länge der zu bearbeitenden Fläche zu erreichen. In diesen Fällen wird das Auftragen mit dem bekannten Handwerkzeug vielmehr mit Unterbrechungen und Ungleichmäßigkeiten bzw. Unsauberkeiten verlaufen. Dies ist vor allem für sichtbare Flächen unakzeptabel.Especially in the case of uncomfortable working positions and for surfaces to be processed with changing inclinations or with unevenness, it is difficult with this hand tool to achieve an even application of the fabric over the length of the surface to be processed. In these cases, the application with the known hand tool will rather be interrupted and uneven or unclean. This is particularly unacceptable for visible surfaces.

Außerdem ist es durch die US-A-3,381,861, die EP-A-0 067 528 und die US-A-4 182 264 bekannt, ein Führungsrad am Handwerkzeug zu befestigen und damit gegebenenfalls einen Fördermechanismus zum Ausbringen der pastösen Masse anzutreiben. Diese Kopplung ermöglicht pro Raddrehung eine stets gleichmäßige aber nicht variable Ausbringmenge und erschwert ein gleichmäßiges, leichtes Vorwärtsbewegen des Handwerkzeugs. Sie führt zu einem ungenauen Verlauf von Klebenähten.In addition, it is known from US-A-3,381,861, EP-A-0 067 528 and US-A-4 182 264 to attach a guide wheel to the hand tool and thus possibly drive a conveyor mechanism for dispensing the pasty mass. This coupling enables a constant, but not variable, spread rate per wheel rotation and makes it difficult to move the hand tool smoothly and easily. It leads to an inaccurate course of glued seams.

Ein erfindungsgemäßes Handwerkzeug mit den kennzeichnenden Merkmalen des Anspruchs 1 hat die Vorteile, daß der mit dem Handwerkzeug Arbeitende dieses lediglich auf die zu bearbeitende Fläche aufsetzen muß und dann das Handwerkzeug selbsttätig bewegt wird. Entsprechend den Merkmalen der folgenden Ansprüche ist über ein Variieren der Vorschubgeschwindigkeit des Führungsmittels oder eine Verstellung des Fördermengendurchflusses die aufzutragende Stoffmenge variierbar. Die Vorschubrichtung und die Vorschubgeschwindigkeit des Handwerkzeuges sind durch Schalterdruck regelbar.A hand tool according to the invention with the characterizing features of claim 1 has the advantages that the person working with the hand tool only has to place it on the surface to be worked and then the hand tool is moved automatically. According to the features of the following claims, the quantity of substance to be applied can be varied by varying the feed rate of the guide means or by adjusting the flow rate of the conveying quantity. The feed direction and the feed speed of the hand tool can be regulated by pressing the switch.

Der Bedienende ist erheblich entlastet, so daß er alle Aufmerksamkeit der Kontrolle der Düsenposition zuwenden kann. Die auf diese Art erreichbare Arbeitsleistung und Arbeitsqualität steigt.The operator is considerably relieved, so that he can pay all attention to the control of the nozzle position. The work performance and work quality achievable in this way increases.

Drei verschiedene Ausführungsbeispiele der Erfindung sind in der nachfolgenden Beschreibung mit zugehöriger Zeichnung erläutert. Es zeigen die Figur 1 ein Handwerkzeug mit handbetätigtem Pressenkolben und motorgetriebenen Führungsmitteln, Figur 2 ein verstellbares Führungsmittel als Einzelheit, Figur 3 ein Handwerkzeug mit motorgetriebenem Pressenkolben mit einem kombinierten, motorgetriebenen Führungsmittel, Figur 4 ein Handwerkzeug mit einem auswechselbaren, motorgetriebenen Führungsmittel.Three different exemplary embodiments of the invention are explained in the following description with the associated drawing. FIG. 1 shows a hand tool with a manually operated press piston and motor-driven guide means, FIG. 2 shows an adjustable guide means as a detail, FIG. 3 shows a hand tool with a motor-driven press piston with a combined, motor-driven guide means, and FIG. 4 shows a hand tool with an exchangeable, motor-driven guide means.

In Figur 1 ist ein erstes Ausführungsbeispiel eines Handwerkzeug 1 mit einer Düse 2 zum Verteilen fließfähiger, pastöser Stoffe mit einem Führungssystem 3 versehen. Die Ausbildung des handkraftbetätigten Handwerkzeugs 1 ist von nebengeordneter Bedeutung für die Erfindung und bekannt aus DE-U-86 02 533. Deswegen wurde auf die Darstellung der Bewegungsübertragungselemente zwischen dem Betätigungshebel 4 und dem Kolben 5 innerhalb des Zylinders 6 verzichtet. Ein für derartige Handwerkzeuge handelsüblicher Behälter 7 für beispielsweise pastöse Stoffe ist in bekannter Weise mit verschiebbarem Boden versehen und im Zylinder 6 dem Druck des Kolbens 5 aussetzbar. Das Handwerkzeug 1 ist mit einem dem Betätigungshebel 4 benachbarten Handgriff 8 versehen.In FIG. 1, a first exemplary embodiment of a hand tool 1 with a nozzle 2 for distributing flowable, pasty substances is provided with a guide system 3. The design of the hand-operated hand tool 1 is of secondary importance for the invention and is known from DE-U-86 02 533. Therefore, the representation of the movement transmission elements between the actuating lever 4 and the piston 5 within the cylinder 6 has been omitted. A commercially available container 7 for such hand tools, for example pasty substances, is provided in a known manner with a displaceable base and can be subjected to the pressure of the piston 5 in the cylinder 6. The hand tool 1 is provided with a handle 8 adjacent to the actuating lever 4.

Der Aufbau der als Führungssystem 3 bezeichneten Baugruppe ist aus Figur 2 ersichtlich.
Dieses besteht aus einem ersten Gehäuseteil 9 und einem zweiten Gehäuseteil 10, die teleskopartig ineinander gelagert sind. Ein im Gehäuseteil 9 gelagerter Antrieb 11 ist ein über eine Welle 12 mit einem Winkelgetriebe 13 gekuppelter Elektromotor. Mit einer Abtriebswelle 14 des Winkelgetriebes 13 ist ein als Rad ausgebildetes Führungsmittel 15 gekoppelt. Dieses Rad ist in einem geringen Abstand benachbart zur Düse 2 angeordnet. Das erste Gehäuseteil 9 ist gemeinsam mit dem Führungsmittel 15, dem Winkelgetriebe 13, der Anund Abtriebswelle 12, 14 und dem Antrieb 11 parallel zu seiner Längsachse verschiebbar in einem Widerlager 16 des zweiten Gehäuseteils 10 angeordnet.The structure of the assembly referred to as guide system 3 can be seen in FIG. 2.
This consists of a first housing part 9 and a second housing part 10, which are telescopically mounted one inside the other. A drive 11 mounted in the housing part 9 is an electric motor coupled via a shaft 12 to an angular gear 13. A guide means 15 designed as a wheel is coupled to an output shaft 14 of the angular gear 13. This wheel is arranged at a short distance from the nozzle 2. The first housing part 9, together with the guide means 15, the bevel gear 13, the input and output shafts 12, 14 and the drive 11, is arranged displaceably parallel to its longitudinal axis in an abutment 16 of the second housing part 10.

In Figur 1 ist das Führungssystem 3 mit schellenartigen Befestigungsmitteln 17 am Handwerkzeug 1 befestigt. Ein Betriebsartenschalter 18 weist drei Schaltpositionen auf: eine erste Schaltposition bestimmt eine das Rad im Uhrzeigersinn drehende Motordrehrichtung, eine zweite Schaltposition bestimmt eine das Rad entgegen dem Uhrzeigersinn drehende Motordrehrichtung und eine zwischen der ersten und zweiten vorgesehene dritte Schaltposition bestimmt die Aus-Stellung für den Antrieb 11 und damit auch für das Führungsmittel 15.In Figure 1, the guide system 3 is fastened to the hand tool 1 with clamp-like fastening means 17. An operating mode switch 18 has three switching positions: a first switching position determines a motor direction of rotation rotating the wheel clockwise, a second switching position determines a motor direction of rotation rotating the wheel counterclockwise and a third switching position provided between the first and second determines the off position for the drive 11 and thus also for the guide means 15.

In Figur 3 ist ein zweites Ausführungsbeispiel eines Handwerkzeuges 31 mit einer Düse 32, einem ersten Antrieb 41 eines Führungssystems 33 und einem zweiten Antrieb 49 zum Fördern des Stoffes durch die Düse 32 hindurch gezeigt. Über ein Getriebe 50 ist der zweite Antrieb 49 mit einer Spindel 51 gekoppelt, die mit einem Schutzrohr 52 versehen ist. Ein Bedienungsschalter 53 schließt oder unterbricht einen nicht mit dargestellten elektrischen Stromkreis, an den der als Elektromotor ausgebildete zweite Antrieb 49 sowie der Antrieb 41 angeschlossen sind. Das Winkelgetriebe 43 ist ein Schneckengetriebe.FIG. 3 shows a second exemplary embodiment of a hand tool 31 with a nozzle 32, a first drive 41 of a guide system 33 and a second drive 49 for conveying the material through the nozzle 32. The second drive 49 is coupled via a gear 50 to a spindle 51 which is provided with a protective tube 52. An operating switch 53 closes or interrupts an electrical circuit, not shown, to which the second drive 49, which is designed as an electric motor, and the drive 41 are connected. The angular gear 43 is a worm gear.

In Figur 4 ist ein drittes Ausführungsbeispiel eines Handwerkzeugs 61 mit einem pistolenartigen, auswechselbaren Zusatzgerät versehen, das das Führungssystem 63 enthält. Ein Handgriff 84 ist zur Aufnahme nicht mit dargestellter Akkus und eines Antriebs geeignet, mit denen das Führungssystem 63 ohne elektrische Anschlußkabel betrieben werden kann. Eine fest mit dem Handgriff 84 verbundene Spannhülse 85 ist so dimensioniert, daß sie mit Heißklebepistolen, Winkelschleifern, Kreis- oder Stichsägen, Fräsen, insbesondere Schattenfugenfräsen kuppelbar ist.In FIG. 4, a third exemplary embodiment of a hand tool 61 is provided with a pistol-like, interchangeable auxiliary device which contains the guide system 63. A handle 84 is not suitable for holding batteries and a drive, with which the guide system 63 can be operated without electrical connection cables. A clamping sleeve 85 firmly connected to the handle 84 is dimensioned such that it can be coupled with hot glue guns, angle grinders, circular or jigsaws, milling, in particular shadow gap milling.

Zwischen dem Antrieb 11,41 und dem Führungsmittel 15, 45, 75 ist eine umschaltbare, nicht mit dargestellte Freilaufkupplung vorgesehen. Ebenfalls nicht mit dargestellt ist ein Zusatzschalter, der kraftbeaufschlagt über das Führungsmittel 15, 45, 75 den Antrieb 11, 41 bzw. auch den zweiten Antrieb 49 einschaltet. Das Einschalten erfolgt beispielsweise beim Aufsetzen des Führungsmittels 15, 45, 75 auf eine Arbeitsfläche. Bei dessen Abheben von der Arbeitsfläche schaltet der Zusatzschalter den Antrieb 11, 41 bzw. den zweiten Antrieb 49 aus.Is between the drive 11, 41 and the guide means 15, 45, 75 a switchable one-way clutch, not shown, is provided. Also not shown is an additional switch which, when subjected to force via the guide means 15, 45, 75, switches on the drive 11, 41 and also the second drive 49. Switching on takes place, for example, when the guide means 15, 45, 75 are placed on a work surface. When it is lifted off the work surface, the additional switch switches off the drive 11, 41 or the second drive 49.

Funktionsbeschreibung: Bei Einsatz des in Figur 1 gezeigten Handwerkzeuges 1 ist zunächst das als Rad ausgebildete Führungsmittel 15 auf die zu bearbeitende Fläche aufzusetzen, so den die Düse 2 so nahe wie notwendig am für den Stoff bestimmten Einbringort positioniert ist. Per Hand wird der Betätigungshebel 4 gespannt, so daß der Kolben 5 einen Förderdruck auf den Behälter 7 ausübt. Daraufhin verläßt der Stoff die Düse 2. Der Betriebsartenschalter 18 muß sich zu diesem Zeitpunkt in der der jeweils gewünschten Führungsrichtung entsprechenden Schaltposition befinden. Sobald der Antrieb 11 das als Rad ausgebildete Führungsmittel 15 antreibt, wird das Handwerkzeug 1 in der vorgewählten Richtung bewegt. Dabei muß der Bedienende nur noch Querabweichungen der Düse 2 von der vorgesehenen Führungsrichtung sowie die Ausbringmenge korrigieren.Functional description: When using the hand tool 1 shown in FIG. 1, the guide means 15 designed as a wheel must first be placed on the surface to be machined, so that the nozzle 2 is positioned as close as necessary to the point of introduction intended for the substance. The operating lever 4 is tensioned by hand so that the piston 5 exerts a delivery pressure on the container 7. The substance then leaves the nozzle 2. At this point in time, the operating mode switch 18 must be in the switching position corresponding to the desired guide direction. As soon as the drive 11 drives the guide means 15 designed as a wheel, the hand tool 1 is moved in the preselected direction. The operator only has to correct transverse deviations of the nozzle 2 from the intended guiding direction and the application rate.

Durch völlige Entlastung des Betätigungshebels 4 und Abheben der Düse 2 und des Führungsmittels 15 von der zu bearbeitenden Fläche wird der Arbeitsgang beendet. Dabei ist durch entsprechendes Schalten des Betriebsartenschalters 18 die Energieversorgung für den Antrieb 11 zu unterbrechen und damit das Führungsmittel 15 zu stoppen.By completely relieving the pressure on the actuating lever 4 and lifting off the nozzle 2 and the guide means 15 from the surface to be machined, the operation is ended. The energy supply for the drive 11 is to be interrupted by appropriately switching the operating mode switch 18 and the guide means 15 is thus stopped.

Das Betreiben eines mit einem zweiten Antrieb 49 versehenen Handwerkzeugs 31, wie es in Figur 3 dargestellt ist, geschieht wie folgt: Nach Aufsetzen des Führungsmittels 45 bzw. des Rades auf die zu bearbeitende Fläche und das Positionieren der Düse 32 in eine vorgesehene Arbeitsstellung sowie nach Einstellen der gewünschten Bewegungsrichtung des Rades am Betriebsartenschalter 48 wird der Bedienungsschalter 53 betätigt. Daraufhin wird der Stromkreis für den zweiten Antrieb 49 sowie für den Antrieb 41 geschlossen.The operation of one provided with a second drive 49 Hand tool 31, as shown in FIG. 3, is done as follows: after placing the guide means 45 or the wheel on the surface to be machined and positioning the nozzle 32 in an intended working position and after setting the desired direction of movement of the wheel on the operating mode switch 48 the operation switch 53 is operated. The circuit for the second drive 49 and for the drive 41 is then closed.

Gleichzeitig mit der Bewegung des Kolbens 35 setzt die Vorschubbewegung des Führungsmittels 45 bzw. des Rades ein. Abhängig von der Stellung des Bedienungsschalters 53 dreht sich das Rad schneller oder langsamer. Über den Bedienungsschalter 53 wird eine nicht mit dargestellte Regelelektronik betätigt.Simultaneously with the movement of the piston 35, the feed movement of the guide means 45 or the wheel begins. Depending on the position of the operating switch 53, the wheel turns faster or slower. Control electronics (not shown) are actuated via the operating switch 53.

Durch Verändern der Betätigungskraft am Bedienungsschalter 53 ist die Ausbringmenge des Stoffs auf der zu bearbeitenden Fläche variierbar.By changing the actuating force on the operating switch 53, the application rate of the substance on the surface to be worked can be varied.

Ist die nicht mit dargestellte Regelelektronik mit dem zweiten Antrieb 49 gekoppelt, so ist bei konstanter Geschwindigkeit des Führungsmittels 45 durch unterschiedliche Betätigungskraft am Bedienungsschalter 53 die Ausbringmenge variierbar.If the control electronics (not shown) are coupled to the second drive 49, the application rate can be varied at a constant speed of the guide means 45 by different actuating force on the operating switch 53.

Zur Beendigung des Arbeitsvorgangs ist der Bedienungsschalter 53 zu entlasten. Die Bewegung des Führungsmittels 45 endet. Durch die Regelelektronik gesteuert führt jedoch der zweite Antrieb 49 eine Drehrichtungsumkehr mit einer definierten Anzahl Drehungen entgegen der ursprünglichen Antriebsrichtung aus. Dadurch wird verhindert, den nach Ende des Arbeitsganges infolge von Elastizität im Kraftübertragungssystem noch Stoff aus der Düse 32 austritt.To complete the work process, the operating switch 53 is to be relieved. The movement of the guide means 45 ends. Controlled by the control electronics, however, the second drive 49 reverses the direction of rotation with a defined number of rotations counter to the original drive direction. This prevents material from emerging from the nozzle 32 after the end of the work cycle due to elasticity in the power transmission system.
