Definitions
- the invention relates to a chop saw device for logs with an infeed conveyor with a centering device arranged at the downstream end, an outfeed conveyor with a clamping device arranged at the upstream end and at least one chop saw arranged between the conveyors and performing a cut from top to bottom.
- the centering device arranged at the end of the infeed conveyor also serves as a clamping device, centering being carried out in the center of the conveyor by lateral clamping.
- the clamping device formed in this way is supplemented by a mechanism which grips into the log from above and below before a saw cut is carried out with the cross-cut saw.
- the end of the discharge conveyor facing the cross-cut saw is also provided with a clamping device in order to be able to also cut the trailing end of the log, which can no longer be held by the centering and clamping device at the end of the feed conveyor.
- the cross-cut saw with two saws arranged next to one another, one of which is a circular saw and the other a swiveling chain saw. Up to a diameter of approx. 45 cm, a quick cross-cut can be made with the circular saw. For larger diameters, the swivel saw is activated and used to make the cut.
- the invention has for its object to improve known cross-cut saws of the type mentioned in terms of the time required with at least the same good function.
- a cross-cut saw device of the type mentioned at the outset is characterized in that the centering device of the infeed conveyor consists of two flaps which are arranged on both sides of the infeed conveyor and are pivotable about the upstream vertical axis of rotation with flaps with straight edges in the vertical direction, and in that in the flaps a measuring arrangement sensing the height of the log is integrated, which is connected to a control for the chop saw.
- the centering device according to the invention with the flaps directed downstream enables a quick and safe centering of the log in front of the cross-cut saw, the log not having to be fixed separately in the vertical direction.
- a suitable abutment against the cut with the chop saw from top to bottom can be effected in a suitable manner by an end roller of the infeed conveyor which can be pressed against the log from below. In this way, time can be saved already when centering the log.
- the measuring arrangement integrated in the flaps for the height of the log is of great importance for controlling the cutting process. It enables a multitude of control actions, which serve to save further time during the cutting processes.
- the measuring arrangement is suitable, in the presence of several saws for the chop cut, the suitable saw that is relevant Fastest cut can be selected.
- control connected to the measuring arrangement can move the cross-cut saw from a starting position to a standby position dependent on the measured log height, in order to save delivery time for the saw to the log.
- the flaps for the further transport of the cut log only partially open as long as a log end between the flaps can still be detected. This saves time both when opening and when closing the flaps for a new centering process. The flaps only open completely after the trailing end of the log has passed through, which can be detected by the measuring arrangement.
- the clamping device of the outlet conveyor can be formed in a simple manner by a pincer-like jaw with a toothed concave edge which can be moved from above in the direction of the outlet conveyor. At this point, the toothed concave edge can be used with advantage since the trunk was previously centered by the centering device.

- Stage A shows a log S entering the infeed conveyor 1 with the flaps 2, the cross-cut saw 5 and the clamping device 9 and the end rollers 7, 8 in the starting position.
- the height of the log S is detected and, with the detected value, the crosscut saw 5 from the starting position (stage A) into a standby position dependent on the detected log height procedure (stage B).
- the end rollers 7, 8 remain in the substantially horizontal position with respect to the infeed belt 1 or the outfeed belt 6.
- the flaps 2 close and thus center the log S approximately in the middle of the infeed conveyor 1.
- the end roller 7 of the infeed conveyor 1 is pressed against the log S from below, which slightly raises the log can be. This lifting process is possible due to the straight edges of the flaps 2 in the vertical direction.
- the saw cut is then made with the chop saw 5 from top to bottom.
- the end roller 8 of the discharge belt 6 is folded down to enable the sawn-off end of the log to fall unimpeded (stage C).
- stage D the flaps 2 are only partially opened to allow the logs to be transported further.
- the flaps 2 are not completely opened to the starting position (stage A) in order to minimize response times.

Abstract
Description
Die Erfindung betrifft eine Kappsägevorrichtung für Stammholz mit einem Einlaufförderer mit einer am stromabwärts gelegenen Ende angeordneten Zentriervorrichtung, einem Auslaufförderer mit einer am stromaufwärts gelegenen Ende angeordneten Klemmvorrichtung und wenigstens einer zwischen den Förderern angeordneten, einen Schnitt von oben nach unten ausführenden Kappsäge.The invention relates to a chop saw device for logs with an infeed conveyor with a centering device arranged at the downstream end, an outfeed conveyor with a clamping device arranged at the upstream end and at least one chop saw arranged between the conveyors and performing a cut from top to bottom.
Derartige Kapplinien sind in zahlreichen Ausführungsformen bekannt. Die am Ende des Einlaufförderers angeordnete Zentriervorrichtung dient zugleich als Klemmvorrichtung, wobei durch eine seitliche Klemmung die Zentrierung in der Fördermitte erfolgt. Üblicherweise wird die so gebildete Klemmvorrichtung durch einen in das Stammholz von oben und unten ergreifenden Mechanismus ergänzt, bevor ein Sägeschnitt mit der Kappsäge durchgeführt wird. Auch das zur Kappsäge zeigende Ende des Auslaufförderers ist mit einer Klemmvorrichtung versehen, um auch das nachlaufende Ende des Stammholzes kappen zu können, das durch die Zentrier- und Klemmvorrichtung am Ende des Einlaufförderers nicht mehr gehalten werden kann.Such cutting lines are known in numerous embodiments. The centering device arranged at the end of the infeed conveyor also serves as a clamping device, centering being carried out in the center of the conveyor by lateral clamping. Usually, the clamping device formed in this way is supplemented by a mechanism which grips into the log from above and below before a saw cut is carried out with the cross-cut saw. The end of the discharge conveyor facing the cross-cut saw is also provided with a clamping device in order to be able to also cut the trailing end of the log, which can no longer be held by the centering and clamping device at the end of the feed conveyor.
Die Durchführung von Kappsägeschnitten an Stammholz ist zeitkritisch. Es besteht daher ein dringendes Bedürfnis, den für jeden Sägeschnitt benötigten Zeitaufwand zu minimieren.The execution of chop saw cuts on logs is time-critical. There is therefore an urgent need to minimize the time required for each saw cut.
Aus diesem Grunde ist es bereits bekannt, die Kappsäge mit zwei nebeneinander angeordneten Sägen auszubilden, wovon eine eine Kreissäge und die andere eine schwenkbare Kettensäge ist. Bis zum Durchmesser von ca. 45 cm kann ein schneller Kappschnitt mit der Kreissäge vorgenommen werden. Für größere Durchmesser wird die Schwenksäge aktiviert und für die Durchführung des Kappschnittes benutzt.For this reason, it is already known to design the cross-cut saw with two saws arranged next to one another, one of which is a circular saw and the other a swiveling chain saw. Up to a diameter of approx. 45 cm, a quick cross-cut can be made with the circular saw. For larger diameters, the swivel saw is activated and used to make the cut.
Der Erfindung liegt die Aufgabe zugrunde, bekannte Kappsägevorrichtungen der eingangs erwähnten Art hinsichtlich des benötigten Zeitbedarfs bei wenigstens gleich guter Funktion zu verbessern.The invention has for its object to improve known cross-cut saws of the type mentioned in terms of the time required with at least the same good function.
Zur Lösung dieser Aufgabe ist eine Kappsägevorrichtung der eingangs erwähnten Art erfindungsgemäß dadurch gekennzeichnet, daß die Zentriervorrichtung des Einlaufförderers aus zwei beiderseits des Einlaufförderers angeordneten, über den Einlaufförderer zueinander jeweils um eine stromaufwärts liegende vertikale Drehachse schwenkbar angeordneten Klappen mit in vertikaler Richtung geraden Kanten besteht und daß in die Klappen eine die Höhe des Stammholzes sensierende Meßanordnung integriert ist, die mit einer Steuerung für die Kappsäge verbunden ist.To achieve this object, a cross-cut saw device of the type mentioned at the outset is characterized in that the centering device of the infeed conveyor consists of two flaps which are arranged on both sides of the infeed conveyor and are pivotable about the upstream vertical axis of rotation with flaps with straight edges in the vertical direction, and in that in the flaps a measuring arrangement sensing the height of the log is integrated, which is connected to a control for the chop saw.
Die erfindungsgemäße Zentriervorrichtung mit den stromabwärts gerichteten Klappen ermöglicht eine schnelle und sichere Zentrierung des Stammholzes vor der Kappsäge, wobei das Stammholz in vertikaler Richtung nicht gesondert festgelegt werden muß. Ein geeignetes Widerlager gegen den Schnitt mit der Kappsäge von oben nach unten kann in geeigneter Weise durch eine gegen das Stammholz von unten drückbare Endrolle des Einlaufförderers bewirkt werden. Auf diese Weise läßt sich bereits bei der Zen-trierung des Stammholzes Zeit einsparen. Für die Steuerung des Kappvorganges ist die in die Klappen integrierte Meßanordnung für die Höhe des Stammholzes von großer Bedeutung. Sie ermöglicht eine Mehrzahl von Steueraktionen, die der weiteren Zeiteinsparung bei den Kappvorgängen dienen. Zum einen ist die Meßanordnung geeignet, bei Vorhandensein mehrerer Sägen für den Kappschnitt die geeignete Säge, die den betreffenden Schnitt am schnellsten ausführen kann, auszuwählen.The centering device according to the invention with the flaps directed downstream enables a quick and safe centering of the log in front of the cross-cut saw, the log not having to be fixed separately in the vertical direction. A suitable abutment against the cut with the chop saw from top to bottom can be effected in a suitable manner by an end roller of the infeed conveyor which can be pressed against the log from below. In this way, time can be saved already when centering the log. The measuring arrangement integrated in the flaps for the height of the log is of great importance for controlling the cutting process. It enables a multitude of control actions, which serve to save further time during the cutting processes. On the one hand, the measuring arrangement is suitable, in the presence of several saws for the chop cut, the suitable saw that is relevant Fastest cut can be selected.
Zum anderen kann die mit der Meßanordnung verbundene Steuerung in einer bevorzugten Ausführungsform die Kappsäge aus einer Ausgangsstellung in eine von der gemessenen Stammholzhöhe abhängigen Bereitschaftsstellung bewegen, um so Zustellungszeit für die Säge zum Stammholz einzusparen.On the other hand, in a preferred embodiment, the control connected to the measuring arrangement can move the cross-cut saw from a starting position to a standby position dependent on the measured log height, in order to save delivery time for the saw to the log.
Der weiteren Zeiteinsparung dient es ferner, wenn in einer weiter bevorzugten Ausführungsform die Klappen für den Weitertransport des gekappten Stammholzes nur teilweise öffnen, solange ein Stammholzende zwischen den Klappen noch detektierbar ist. Hierdurch wird eine Zeiteinsparung sowohl beim Öffnen als auch beim Wiederschließen der Klappen für einen neuen Zentriervorgang erreicht. Die vollständige Öffnung der Klappen findet erst nach Durchlaufen des nachlaufenden Stammholzendes statt, was von der Meßanordnung detektierbar ist.Further time saving is also achieved if, in a further preferred embodiment, the flaps for the further transport of the cut log only partially open as long as a log end between the flaps can still be detected. This saves time both when opening and when closing the flaps for a new centering process. The flaps only open completely after the trailing end of the log has passed through, which can be detected by the measuring arrangement.
Die Klemmvorrichtung des Auslaufsförderers kann in einfacher Weise durch eine von oben in Richtung Auslaufförderer bewegbare zangenähnliche Backe mit einer gezahnten konkaven Kante gebildet sein. An dieser Stelle ist die gezahnte konkave Kante mit Vorteil einsetzbar, da der Stamm durch die Zentriereinrichtung vorher bereits zentriert war.The clamping device of the outlet conveyor can be formed in a simple manner by a pincer-like jaw with a toothed concave edge which can be moved from above in the direction of the outlet conveyor. At this point, the toothed concave edge can be used with advantage since the trunk was previously centered by the centering device.
Die Klemmvorrichtung zur Durchführung eines Endkappschnitts am nachlaufenden Ende des Stammholzes ist wirksam steuerbar und bleibt unwirksam gesteuert, wenn sich ein ausreichend langes Ende des Stammholzes auf dem Einlaufförderer befindet.The clamping device for performing an end cut at the trailing end of the log is effectively controllable and remains ineffective when there is a sufficiently long end of the log on the infeed conveyor.
Für diesen Vorgang wird vorzugsweise eine Endrolle des Auslaufbandes von unten gegen das Stammholz verfahren, um als Gegenlager für die Klemmvorrichtung zu dienen.For this process, an end roller of the discharge belt is preferably moved from below against the log to serve as a counter bearing for the clamping device.
Die Meßanordnung in den Klappen kann vorzugsweise durch vertikal untereinander angebrachte optische Sensoren, vorzugsweise Lichtschranken, gebildet sein.The measuring arrangement in the flaps can preferably be formed by optical sensors, preferably light barriers, arranged vertically one below the other.
Die Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden. Es zeigen:

Die Zeichnung läßt ein Einlaufband als Einlaufförderer 1 erkennen, zu dessen beiden Seiten am stromabwärts liegenden Ende Klappen 2 angeordnet sind, die als Zentriervorrichtung um an ihren stromaufwärts liegenden Enden angeordneten vertikalen Drehachsen zum zentrierten Ergreifen eines Stammholzes S aufeinander zu schwenkbar sind. Am Ende des Einlaufbandes 1 ist eine Kappsäge 5 mit einem Sägegehäuse 4 angeordnet. Fluchtend mit dem Einlaufband schließt sich stromabwärts von der Kappsäge 5 ein Auslaufband als Auslaufförderer 6 an. Nahe beiderseits der Kappsäge 5 sind Einlaufsband 1 und Auslaufband 6 mit jeweils einer Endrolle 7, 8 versehen, die heb- und senkbar und in Form von Doppelkegelrollen ausgebildet sind.The drawing shows an infeed belt as an infeed
Oberhalb des zur Kappsäge 5 zeigenden Endes des Auslaufbandes 6 befindet sich eine Klemmvorrichtung 9 in Form einer von oben nach unten bewegbaren Klemmbacke, die eine (nicht dargestellte) konkave und gezahnte Klemmkante aufweist. Das Stadium A zeigt ein auf dem Einlaufband 1 einlaufendes Stammholz S mit den Klappen 2, der Kappsäge 5 und der Klemmvorrichtung 9 sowie den Endrollen 7, 8 in Ausgangsstellung.Above the end of the
Beim Durchlaufen der Meßanordnung 3 in den Klappen 2 wird die Höhe des Stammholzes S detektiert und mit dem detektierten Wert die Kappsäge 5 aus der Ausgangsposition (Stadium A) in eine von der detektierten Stammholzhöhe abhängige Bereitschaftsstellung verfahren (Stadium B). Die Endrollen 7, 8 verbleiben in der im wesentlichen horizontalen Lage zu dem Einlaufband 1 bzw. Auslaufband 6.When passing through the
Nachdem das Stammholz S unter die Kappsäge 5 gefahren ist, schließen die Klappen 2 und zentrieren somit das Stammholz S etwa in der Mitte des Einlaufbandes 1. Gleichzeitig wird die Endrolle 7 des Einlaufbandes 1 von unten gegen das Stammholz S gedrückt, wodurch das Stammholz etwas angehoben werden kann. Dieser Anhebevorgang ist aufgrund der in vertikaler Richtung geraden Kanten der Klappen 2 möglich.After the log S has been driven under the crosscut saw 5, the
Anschließend erfolgt der Sägeschnitt mit der Kappsäge 5 von oben nach unten. Dabei ist die Endrolle 8 des Auslaufbandes 6 nach unten abgeklappt, um ungehindertes Herabfallen des abgesägten Endes des Stammholzes zu ermöglichen (Stadium C).The saw cut is then made with the chop saw 5 from top to bottom. The end roller 8 of the
Anschließend (Stadium D) werden die Klappen 2 nur teilweise geöffnet, um einen Weitertransport des Stammholzes zu erlauben. Eine vollständige Öffnung der Klappen 2 in die Ausgangsstellung (Stadium A) unterbleibt, um Einstellzeiten zu minimieren. Aus dem gleichen Grunde ist auch die Kappsäge 5 nicht in ihrer Ausgangsstellung (Stadium A) sondern in ihrer Bereitschaftsstellung (Stadium B) verfahren.Afterwards (stage D) the
Nach einem erneuten Klemmen durch die Klemmvorrichtung (Stadium E) wird ein erneuter Schnitt durchgeführt. Befindet sich dabei nur noch ein kurzes nachlaufendes Ende in der Klemmvorrichtung 2 kann bereits die Klemmvorrichtung 9 wirksam geschaltet werden, wobei die hochgedrückte Endrolle 8 als Gegenlager dient.After being clamped again by the clamping device (stage E), a new cut is carried out. If there is only a short trailing end in the
Anschließend wird das Reststück des Stammholzes S weitertransportiert (Stadium F), mit der Klemmvorrichtung 9 im Zusammenwirken mit der Endrolle 8 geklemmt und dann der letzte Kappschnitt am nachlaufenden Ende des Stammholzes S ausgeführt.The remaining piece of log S is then transported on (stage F), clamped with the clamping device 9 in cooperation with the end roller 8, and then the last cut is made at the trailing end of the log S.
Die erfindungsgemäße Kappsägevorrichtung verwirklicht minimale Klemm- und Zentriervorgänge mit minimalen Zustellwegen ohne Einbuße der Funktionsfähigkeit, so daß eine gleichgute Kappfunktion in kürzerer Bearbeitungszeit erreicht werden kann.The cross-cut saw device according to the invention realizes minimal clamping and centering processes with minimal delivery paths without loss of functionality, so that an equally good cross-cutting function can be achieved in a shorter processing time.
