Description

Die Erfindung betrifft ein pneumatisch betätigbares Umreifungshandgerät gemäß Oberbegriff des Anspruchs 1.The invention relates to a pneumatic operable Umreifungshandgerät according to Preamble of claim 1.

Derartige Umreifungshandgeräte dienen dazu, Packstücke mit Stahlband zu umreifen. Um diese Handgeräte griffgünstig anordnen zu können und um sicherzustellen, dass der Benutzer das Handgerät einfach bedienen und bewegen kann, sind solche Handgeräte an einem so genannten Balancer aufgehängt. Der Balancer besteht beispielsweise aus einem Stahlseil oder dergleichen mit einem federnden Pendelzug. Das Ende dieses Seiles kann in den Halter eingehängt werden, so dass das Gerät vom Benutzer in beliebiger Höhe über dem Erdboden anzuordnen ist und in der gewünschten Stellung verharren kann. Sofern der Benutzer das Gerät bedienen will, kann er es leicht mit der Hand erfassen und auch in beliebige Richtungen bewegen. Solche Umreifungshandgeräte weisen eine Handhabe mit Bediengriff und Betätigungsschaltern auf, wobei das Gerät insgesamt an der Handhabe gehalten und geführt werden kann. Durch Betätigung von Betätigungsschaltern, die im Griffbereich des Benutzers liegen, können bestimmte Funktionen des Stellantriebes ausgelöst werden. Mittels des Stellantriebes ist es möglich, das Spannteil zum Spannen des eingelegten Umreifungsbandes zu betätigen und auch die Verschließeinrichtung zum Verschließen der überlappenden Bandenden in Gang zu setzen. Vornehmlich zum Öffnen und Schließen des Spannteiles ist eine geringe Schwenkbeweglichkeit der Handhabe relativ zum Gehäuse erforderlich. Aus diesem Grunde ist die Handhabe relativ zum Gehäuse schwenkbeweglich gehaltert. Da auch der pneumatische Stellantrieb in den Teilen des Gerätes angeordnet ist, die Bestandteile der Handhabe sind, ist es im Stand der Technik bekannt, den Anschlussstutzen zum Anschluss einer Druckluftleitung zur Betätigung des pneumatischen Stellantriebes zum freien Ende der Handhabe vorzusehen. In der Handhabe, die als zylindrischer Hohlkörper ausgebildet ist, ist vom freien Ende der Handhabe aus gesehen, ein mittels Druckluft betriebener Rotor und daran anschließend ein Getriebe angeordnet. Die Druckluft wird beispielsweise über einen an der Stirnkappe der Handhabe vorgesehenen Stutzen zugeführt, so dass der Rotor hierdurch in Drehung versetzt werden kann, wobei die Druckluft nach dem Passieren des Rotors wieder zu der Abschlusskappe zurückgeführt und an dieser nach außen abgeführt wird.Such strapping hand tools serve To strap packages with steel band. Around Hand tools to arrange handy and can to make sure the user does that Easy to operate and move the handset, are such handsets on a so-called Balancer hung up. The balancer exists for example, from a steel cable or The like with a springy train. The End of this rope can in the holder be hung so that the device from Users at any height above the ground is to be arranged and in the desired position can persist. Unless the user has the device he wants to operate it easily with his hand capture and in any direction move. Such Umreifungshandgeräte exhibit a handle with control handle and Operating switches on, the device Total held on the handle and guided can be. By actuating operating switches, in the grip area of the user lie, certain functions of the Actuator are triggered. By means of the Actuator, it is possible, the clamping part for tensioning the inserted strapping band operate and also the closing device for closing the overlapping band ends in To set a course. Mainly for opening and Closing the clamping part is a small one Pivot mobility of the handle relative to Housing required. For this reason, the Handle pivotally relative to the housing supported. As well as the pneumatic Actuator in the parts of the device is arranged, the components of the handle are known in the art, the Connecting piece for connecting a Compressed air line for actuating the pneumatic actuator to the free end to provide the handle. In the handle, the is formed as a cylindrical hollow body, is seen from the free end of the handle, a driven by compressed air rotor and subsequently arranged a gear. The Compressed air is for example via a s.der End cap of the handle provided neck supplied, so that the rotor thereby in Rotation can be offset, the Compressed air after passing the rotor again returned to the end cap and on this is discharged to the outside.

Diese Anordnung wird als ungünstig angesehen, weil der Anschlussschlauch der Druckluftleitung, der auf den Anschlussstutzen gesteckt werden muss, bei der Bedienung des Gerätes störend ist.This arrangement is considered unfavorable because the connecting hose of the Compressed air line on the connecting piece must be plugged in the operation of the Device is disturbing.

Darüber hinaus ist es bei herkömmlicher Ausbildung notwendig, einen im Gehäuse innen liegend angeordneten Ventilblock, der mit gehäuseseitig angeordneten Bestätigungsschaltern bedienbar ist, über eine Leitungsverbindung mit dem pneumatischen Stellantrieb zu koppeln. Hierzu wird üblicherweise eine schlauchartige Verbindung vorgesehen, die für die Funktion ebenfalls störend ist. Diese schlauchartige Verbindung ist zudem bruchempfindlich.In addition, it is at conventional Training necessary, one in the housing inside lying arranged valve block, with arranged on the housing side Confirmation switches can be operated via one Line connection with the pneumatic Couple actuator. For this purpose is usually a hose-like connection provided for the function as well is disturbing. This hose-like connection is also sensitive to breakage.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Umreifungshandgerät gattungsgemäßer Art zu schaffen, welches einen höheren Bedienkomfort und eine höhere Betriebssicherheit aufweist.Based on this state of the art The invention is based on the object, a Umreifungshandgerät generic type too create, which a higher ease of use and has a higher reliability.

Zur Lösung dieser Aufgabe wird vorgeschlagen, dass der Einlass am gehäusenahen Ende der Handhabe vorgesehen und durch einen Wandungsdurchbruch der Wandung der Handhabe gebildet ist, der in einen Ringkanal mündet, der einen gehäusenahen Endbereich des Getriebes umgibt und zum gehäuseseitigen Ende der Handhabe abgedichtet ist, wobei an den Ringkanal im Wesentlichen axial gerichtete Nuten anschließen, die über die gesamte Länge des Getriebes bis zum Lufteinlass des Rotors verlaufen, wobei der Rotor gegenüber der ihn umgebenden Wandung abgedichtet ist.To solve this problem it is proposed that the inlet at the housing end of the Handle provided and by a Wall breakthrough of the wall of the handle is formed, which opens into an annular channel, the one end of the housing near the gearbox surrounds and to the housing end of the Handle is sealed, being attached to the Ring channel substantially axially directed Connect grooves over the entire length of the gearbox to the air inlet of the rotor run, with the rotor opposite him surrounding wall is sealed.

Durch diese Anordnung ist erreicht, dass der Druckluftschlauch nicht am Ende der Handhabe auf den entsprechenden Stutzen aufgesetzt werden muss, sondern die Luftzuführung über das gehäuseseitige Ende der Handhabe erfolgt, so dass die Handhabung insgesamt vereinfacht und die Betriebssicherheit verbessert ist.By this arrangement it is achieved that the Compressed air hose not at the end of the handle placed on the corresponding socket must be, but the air supply over the housing-side end of the handle is done, so that handling is simplified overall and the operational safety is improved.

Gemäß der Erfindung ist der Anschlussstutzen zum Anschluss der Druckluftleitung nicht mehr an der Handhabe vorgesehen, sondern am Gehäuse selbst, und zwar an der Gehäuseseite, über der auch die Halteöse oder dergleichen für den Balancer vorgesehen ist. Damit kann die Druckluftleitung parallel zu dem beispielsweise von der Gebäudedecke oder von einem oberhalb des Bedienplatzes angeordneten Gestell herabhängenden Balancer geführt werden, wobei die Anordnung parallel zum Verlauf des Balancers erfolgt, so dass die Druckluftleitung den Benutzer bei der Bedienung des Umreifungshandgerätes nicht stört. Die Luftführung von der Druckluftleitung über den Anschlussstutzen erfolgt dann über den gehäuseinnenliegend vorgesehenen Ventilblock zu dem pneumatischen Stellantrieb, wobei die Druckluft im Bereich des gehäuseseitigen Endes des Getriebes in die Handhabe eingeführt wird, wobei das Handhabungsgehäuse in Richtung auf das Gehäuse abgedichtet ist, so dass der Luftstrom nur zum freien Ende der Handhabe hin erfolgen kann. Die Luft ist dann über die Nuten im Innenmantel der Handhabe am Getriebekörper vorbeigeführt und über einen Ringkanal zu entsprechenden Einlassöffnungen des Rotorgehäuses leitet. Der Rotor kann so betrieben werden, wobei die Abluft an der Endkappe der Handhabe durch Schlitze oder Lochungen abgeführt werden kann. Um die Verbindung zwischen dem Ventilblock und dem pneumatischen Stellantrieb herzustellen, ist eine rohrartige Drehdurchführung einerseits fest mit dem Ventilblock verbunden, der gehäuseseitig installiert ist und andererseits drehbar in die Handhabe eingeleitet. Diese Anschlussstelle an die Handhabe ist koaxial zur Schwenkachse der Handhabe gerichtet. Es ist somit eine hohe Betriebssicherheit und ein störungsfreier Luftübergang zum pneumatischen Stellantrieb (Rotor) gewährleistet, ohne dass der Bedienkomfort des Benutzers eingeschränkt ist. According to the invention, the connecting piece to connect the compressed air line no longer provided on the handle, but on the housing itself, on the side of the case, above the also the holding eye or the like for the Balancer is provided. This can be the Compressed air line parallel to the example from the building ceiling or from above the operator's desk arranged frame drooping balancer, whereby the arrangement parallel to the course of Balancers done so that the compressed air line the user in the operation of the Strapping handset does not bother. The Air duct from the compressed air line over the Connecting piece is then over the housing internally provided valve block to the pneumatic actuator, wherein the Compressed air in the area of the housing end the transmission is introduced into the handle, with the handling housing in the direction of the housing is sealed, so that the Air flow only towards the free end of the handle can be done. The air is then over the grooves in the inner casing of the handle on the gear body passed and over a ring channel to corresponding inlet openings of the Rotor housing conducts. The rotor can do that be operated, the exhaust air at the End cap of the handle through slots or Perforations can be dissipated. To the Connection between the valve block and the to produce pneumatic actuator is a tubular rotary union on the one hand firmly connected to the valve block, the is installed on the housing side and on the other hand rotatably introduced into the handle. These Connection point to the handle is coaxial with Directed pivot axis of the handle. It is thus a high operational safety and a trouble-free air transfer to the pneumatic Actuator (rotor) ensures without the ease of use of the user restricted is.
