Abstract
Description
Die Erfindung betrifft eine Wippsäge zum Ablängen von Brennholz etc. mit einem Gestell, auf dem mindestens ein stationäres, in Schneidrichtung antreibbares Schneidorgan aufgenommen ist, und mit einer um eine quer zur Schnittebene verlaufende Schwenkachse schwenkbar am Gestell angebrachten Wippe, die mit einem zu ihrer Schwenkachse parallelen, prismenförmigen Aufnahzmekanal zur Aufnahme von Schnittgut versehen ist.The invention relates to a Jig saw for cutting firewood, etc. with a frame on which at least one stationary, drivable in the cutting direction cutting member is received, and with a about a transverse to the cutting plane pivot axis pivotally mounted on the frame rocker, with one to its pivot axis parallel, prismatic receiving channel is provided for receiving clippings.
Eine Wippsäge dieser Art ist z.B. aus der
Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, eine Anordnung eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln so zu verbessern, dass eine vergleichsweise einfache Entleerbarkeit des Aufnahmekanals erreicht wird.On this basis, it is therefore an object of the present invention to improve an arrangement of the type mentioned with simple and inexpensive means so that a comparatively simple emptying of the receiving channel is achieved.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass eine den Aufnahmekanal enthaltende Kippmulde vorgesehen ist, die um eine quer zur Kanalachse verlaufende, etwa horizontale Kippachse kippbar auf der Wippe aufgenommen ist.This object is achieved in that a receiving channel containing the dump body is provided, which is added to a tilting axis extending transversely to the channel axis, approximately horizontal tilting on the rocker.
Diese Maßnahmen stellen in vorteilhafter Weise sicher, dass das abgelängte Schnittgut einfach abgekippt werden kann. Mehrere, gleichzeitig hergestellte Abschnitte können dabei in vorteilhafter Weise mit einem Abkippvorgang gleichzeitig abgekippt werden. Die erfindungsgemäßen Maßnahmen ermöglichen daher insbesondere bei Anordnungen mit mehreren Schneidorganen zur gleichzeitigen Erzielung mehrerer Abschnitte eine besonders einfache und rationelle Bedienbarkeit. Die erfindungsgemäßen Maßnahmen eignen sich daher besonders für Anordnungen, bei denen mehrere, mit seitlichem Abstand parallel nebeneinander angeordnete Schneidorgane vorgesehen sind.These measures ensure advantageously that the cut grass clippings can be easily dumped. Several, simultaneously produced sections can be tipped at the same time advantageously with a Abkippvorgang. The measures according to the invention therefore make possible a particularly simple and rational operation, in particular in arrangements with several cutting members for the simultaneous achievement of several sections. The measures according to the invention are therefore particularly suitable for arrangements in which a plurality of cutting elements arranged parallel next to one another at a lateral distance are provided.
Eine weitere zweckmäßige Maßnahme kann darin bestehen, dass die Kippachse im Bereich eines seitlichen Endes der Kippmulde vorgesehen ist. Dies gestattet in vorteilhafter Weise einen großen Kippwinkel.Another expedient measure may be that the tilting axis is provided in the region of a lateral end of the dump body. This advantageously allows a large tilt angle.
Zweckmäßig kann dabei an das der Kippachse benachbarte Ende der Kippmulde ein Abwurfstutzen angesetzt sein. Dieser ermöglicht die Erzielung einer gewünschten Abwurfbahn und stellt daher sicher, dass der Abwurf zweckmäßig in einer gewissen Entfernung von der Säge erfolgt, was zur Vermeidung von Behinderungen erwünscht ist.Appropriately may be attached to the tilting axis adjacent end of the dump body a discharge nozzle. This allows the achievement of a desired discharge track and therefore ensures that the discharge is appropriate at a certain distance from the saw, which is desirable to avoid obstruction.
Zur Erzielung einer weiteren Bedienungserleichterung kann der Kippmulde mindestens eine den Kippvorgang unterstützende Feder zugeordnet sein. Hierdurch wird Ermüdungserscheinungen sowie erfahrungsgemäß hierdurch verursachten Unfällen wirksam vorgebeugt.To achieve a further ease of operation of the dump body can be assigned at least one spring supporting the tilting operation. As a result, fatigue phenomena and experience caused by this accident is effectively prevented.
Zweckmäßig kann die Kippmulde mit einer im Bereich ihres von der Kippachse entfernten Endes vorgesehenen Griffanordnung versehen sein. Diese Maßnahme ermöglicht eine sinnfällige Bedienung der Kippmulde sowie der diese enthaltenden Wippe mit ein und derselben Griffanordnung.Suitably, the dump body may be provided with a handle arrangement provided in the region of its end remote from the tilt axis. This measure allows a meaningful operation of the dump body and the rocker containing this with one and the same handle assembly.
In weiterer Fortbildung der übergeordneten Maßnahmen kann die Kippmulde als im Querschnitt etwa v-förmig profiliertes Kanalstück ausgebildet sein, das in einer zugeordneten, querschnittsmäßig angepassten, das obere, schwenkachsferne Ende der Wippe bildenden Trägerkonsole aufnehmbar und hieran gelagert ist. Diese Maßnahmen ergeben eine sehr stabile und robuste Anordnung.In a further development of the higher-level measures, the dump body can be designed as a channel piece profiled in cross-section approximately in the shape of a V, which is in a assigned, adapted in cross-section, the upper, schwenkachsferne end of the rocker forming carrier bracket is receivable and stored thereon. These measures result in a very stable and robust arrangement.
Vorteilhaft können der Kippmulde eine ihre obere Zugangsöffnung übergreifende, schwenkbare Abdecköffnung und eine in den Aufnahmekanal eingreifende, schwenkbare Niederhalteeinrichtung zugeordnet sein, die vorteilhaft in Abdeck- bzw. Niederhalteeinrichtung relativ zueinander bewegbar sind. Diese Maßnahmen gewährleisten eine hohe Sicherheit gegen Arbeitsunfälle.Advantageously, the dump body can be associated with a pivotable cover opening which engages over its upper access opening and a pivotable hold-down device which engages in the receiving channel and can advantageously be moved relative to one another in the cover or hold-down device. These measures ensure a high level of safety against occupational accidents.
Um diese Sicherheit noch weiter zu erhöhen, ist die Kippmulde zweckmäßig nur in einer vom Gestell abgeschwenkten Endstellung der Wippe hochkippbar, in welcher Stellung die Wippe mittels einer mit der geöffneten, vorzugsweise an der Wippe angebrachten Abdeckeinrichtung zusammenwirkenden Verriegelungseinrichtung gegen Anschwenken an das Gestell blockiert ist. In allen anderen Stellungen der Wippe sollen die mit der Verriegelungseinrichtung zusammenwirkende Abdeckeinrichtung und durch diese die hiervon übergriffene Kippmulde blockiert sein. Hierdurch ist sichergestellt, dass die Kippmulde nur hochgeschwenkt werden kann, wenn sie sich sicher außerhalb des Wirkbereichs der Schneidorgane befindet.To increase this safety even further, the dump body is expedient hochkippbar only in a pivoted-off from the frame end position of the rocker, in which position the rocker is blocked by means of a cooperating with the open, preferably attached to the rocker cover locking device against pivoting against the frame. In all other positions of the rocker cooperating with the locking device covering device and be blocked by this overturned dump body. This ensures that the dump body can only be swung up when it is safely outside the effective range of the cutting organs.
Weitere vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den restlichen Unteransprüchen angegeben und aus der nachstehenden Beispielsbeschreibung anhand der Zeichnung näher entnehmbar.Further advantageous embodiments and expedient developments of the parent measures are specified in the remaining subclaims and from the following description of the example with reference to the drawing closer.
