Description
Die Erfindung betrifft eine Durchlaufsägevorrichtung mit mehreren Sägeblättern zum Aufteilen oder Nuten von Werkstücken, welche vorzugsweise plattenförmig ausgebildet sind, nach dem Oberbegriff von Anspruch 1. Eine solche Vorrichtung ist aus der
Es sind bereits Durchlaufsägen zum Aufteilen von Plattenwerkstoffen mit einer Schneidwelle, auf der einzelne Sägeblätter aufgereiht und fest auf dieser Welle geklemmt oder gespannt sind, bekannt. Eine solche Vorrichtung ist beispielsweise in einem Prospekt der Anmelderin "Sägenprogramm FSL und FSQ zum Aufteilen von Plattenwerkstoffen" beschrieben. Dieses Prinzip hat den Nachteil, dass für eine Veränderung der einzelnen zu schneidenden Streifenbreiten die Sägeblätter erst gelöst, verstellt und wieder geklemmt oder aufgespannt werden müssen. Da eine Verstellung der Sägeblätter während des Betriebs der Maschine nicht möglich ist muss mit Stillstands- und Umrüstzeiten gerechnet werden wenn nachfolgende Werkstücke in schmalere Werkstücke mit anderer Streifenbreite zersägt werden sollen.There are already continuous saws for splitting plate materials with a cutting shaft, lined up on the individual saw blades and firmly clamped or stretched on this wave known. Such a device is described for example in a brochure of the applicant "saw program FSL and FSQ for splitting plate materials". This principle has the disadvantage that for a change in the individual strip widths to be cut, the saw blades must first be loosened, adjusted and re-clamped or clamped. Since it is not possible to adjust the saw blades during machine operation, standstill and changeover times must be expected when subsequent workpieces are to be sawn into narrower workpieces with a different strip width.
Wie ebenso in dem oben genannten Prospekt offenbart, wurden alternativ dazu Durchlaufsägen entwickelt, bei denen jedes Sägeblatt einen eigenen Antriebsmotor sowie eine eigene Verstelleinrichtung aufweist, so dass die Streifenbreiten während des Betriebs der Maschine von außen verstellt werden können. Nachteilig hierbei ist jedoch der hohe Aufwand, für jedes Aggregat einen eigenen Antriebsmotor vorzusehen. Der entsprechende Platzbedarf des Antriebsmotors bestimmt die minimal mögliche zu schneidende Streifenbreite, wodurch die Variabilität der Säge beeinträchtigt wird.As also disclosed in the above-mentioned brochure, continuous saws were alternatively developed in which each saw blade has its own drive motor and its own adjustment, so that the strip widths are adjusted during operation of the machine from the outside can. The disadvantage here, however, is the high cost of providing a separate drive motor for each unit. The corresponding footprint of the drive motor determines the minimum possible strip width to be cut, whereby the variability of the saw is impaired.

Der Erfindung liegt das technische Problem zugrunde, eine Durchlaufsägevorrichtung zu schaffen, die bei geringen Stillstands- und Umrüstzeiten eine hohe Variabilität besitzt.The invention is based on the technical problem of providing a continuous sawing device which has a high variability at low standstill and changeover times.
Dieses technische Problem wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Besonders bevorzugte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This technical problem is solved by a device having the features of
Der Erfindung liegt der Gedanke zugrunde, eine Durchlaufsägevorrichtung zum Aufteilen oder Nuten von plattenförmigen Werkstücken in der Weise zu gestalten, dass der Drehantrieb und die Sägebreitenfestlegung weitgehend voneinander entkoppelt sind. Zu diesem Zweck ist erfindungsgemäß vorgesehen, dass bei einer Durchlaufsägevorrichtung der eingangs genannten Art die Sägeelemente derart mit der Antriebswelle verbunden sind, dass sie in Längsrichtung der Antriebswelle verschiebbar sind.The invention is based on the idea of designing a continuous saw device for splitting or grooving plate-shaped workpieces in such a way that the rotary drive and the saw width setting are largely decoupled from each other. For this purpose, the invention provides that in a continuous sawing device of the type mentioned, the sawing elements are connected to the drive shaft so that they are displaceable in the longitudinal direction of the drive shaft.
Hierdurch wird erreicht, dass selbst während des Betriebes der Vorrichtung, d.h. ohne jegliche Stillstands- und Umrüstzeiten, praktisch jede Streifenbreite eingestellt werden kann.This ensures that even during operation of the device, i. without any downtime and changeover times, virtually any strip width can be adjusted.
Um eine stabile und dennoch verschiebbare Drehantriebsbeziehung zwischen den Sägeelementen und der Antriebswelle zu erzielen, ist gemäß der Erfindung vorgesehen, dass die Sägeelemente zumindest ein Sägeblatt und einen hiermit verbundenen Flansch aufweisen.In order to achieve a stable, yet displaceable rotary drive relationship between the sawing elements and the drive shaft, it is provided according to the invention that the sawing elements have at least one saw blade and a flange connected thereto.
Ferner ist gemäß der Erfindung vorgesehen, dass die Sägeelemente mit der Antriebswelle jeweils über ein Übertragungselement verbunden sind. Der Einsatz eines Übertragungselements ermöglicht den Ausgleich von Fertigungstoleranzen sowie eine Verringerung der Bauteile, die bei einem Wechsel eines Sägeblatts bzw. Sägeelements ausgetauscht werden müssen. Dabei sind die Übertragungselemente mit dem jeweiligen Sägeelement bevorzugt formschlüssig verbunden, wodurch die bereits oben diskutierten Vorteile ebenfalls erzielt werden.Furthermore, it is provided according to the invention that the sawing elements are each connected to the drive shaft via a transmission element. The use of a transmission element allows the compensation of manufacturing tolerances and a reduction of the components that must be replaced when changing a saw blade or saw element. In this case, the transmission elements are preferably positively connected to the respective saw element, whereby the advantages already discussed above are also achieved.
Darüber hinaus ist gemäß der Erfindung vorgesehen, dass zwischen den Übertragungselementen und dem jeweiligen Sägelement mindestens ein elastisches Element vorgesehen ist, insbesondere mindestens ein O-Ring. Auf diese Weise wird neben dem Ausgleich von Fertigungstoleranzen eine Schwingungsdämpfung während des Betriebs der Durchlaufsägenvorrichtung erzielt, sodass sich ein verschleiß-und geräuscharmer sowie präziser Betrieb der erfindungsgemäßen Durchlaufsägevorrichtung ergibt.In addition, it is provided according to the invention that at least one elastic element is provided between the transmission elements and the respective sawing element, in particular at least one O-ring. In this way, in addition to the compensation of manufacturing tolerances, vibration damping is achieved during operation of the continuous saw device, resulting in a wear and quiet and precise operation of the continuous saw device according to the invention.
Wie bereits oben stehend ausgeführt, findet zwischen der Antriebswelle und den jeweiligen Sägeelementen primär ein Drehantrieb statt. Um darüber hinaus eine präzise und richtungsstabile Führung der Sägeelemente und einen entsprechend präzisen Sägebetrieb zu erzielen, ist gemäß einer Weiterbildung der Erfindung vorgesehen, dass die Flansche der Sägeelemente jeweils drehbar in einem Lagerelement gelagert sind, das an einem Grundgestell der Durchlaufsägevorrichtung angebracht ist. Dabei ist es besonders bevorzugt, dass die Lagerelemente in Längsrichtung der Antriebswelle entlang dem Grundgestell verschiebbar sind, sodass die Sägeelemente auch bei einer Verstellung der Sägebreite eine fest definierte Beziehung zu den jeweiligen Lagerelementen beibehalten können.As already stated above, takes place between the drive shaft and the respective sawing elements primarily a rotary drive. Moreover, in order to achieve a precise and directionally stable guidance of the saw elements and a correspondingly precise sawing operation, it is provided according to a development of the invention that the flanges of the sawing elements are each rotatably mounted in a bearing element which is attached to a base frame of the continuous saw device. It is particularly preferred that the bearing elements in the longitudinal direction of the drive shaft along the base frame are displaceable, so that the sawing elements can maintain a fixed relationship with the respective bearing elements even with an adjustment of the saw width.
Die Verschiebbarkeit der Sägeelemente entlang der Antriebswelle kann im Rahmen der vorliegenden Erfindung auf unterschiedlichste Art und Weise erzielt werden. Gemäß einer Weiterbildung der Erfindung ist jedoch vorgesehen, dass die Sägeelemente in Drehrichtung der Antriebswelle formschlüssig verbunden sind, sodass auf Klemmelemente, Spannschrauben oder dergleichen verzichtet werden kann und ermöglicht wird, dass die Sägeelemente jederzeit - auch während des Betriebes - entlang der Antriebswelle verschoben werden können.The displaceability of the saw elements along the drive shaft can be achieved in the context of the present invention in various ways. According to one embodiment of the invention, however, it is provided that the saw elements are positively connected in the direction of rotation of the drive shaft, so that can be dispensed with clamping elements, clamping screws or the like and allows the saw elements at any time - even during operation - can be moved along the drive shaft ,
Zur Erzielung des Formschlusses können Antriebswelle und Sägeelemente prinzipiell einen beliebigen Querschnitt besitzen, der beispielsweise auch Vertiefungen, Vorsprünge oder dergleichen aufweisen kann. Um jedoch auf einfach und wirksame Weise einen Formschluss in Drehrichtung der Antriebswelle zu erzielen, ist es gemäß einer Weiterbildung der Erfindung bevorzugt, dass die Antriebswelle einen von einer Kreisform abweichenden Querschnitt, insbesondere einen zumindest annähernd polygonalen Querschnitt, aufweist.In order to achieve positive engagement, the drive shaft and sawing elements can in principle have any desired cross-section, including depressions, projections, for example or the like. However, in order to achieve a positive and effective manner in the direction of rotation of the drive shaft, it is preferred according to a development of the invention that the drive shaft has a deviating from a circular cross-section, in particular an at least approximately polygonal cross-section.
Die Verstellung der jeweiligen Sägeelemente oder auch Lagerelemente kann im Rahmen der vorliegenden Erfindung auf beliebige Weise erfolgen, beispielsweise auch durch manuelle Verstellung jedes einzelnen Bauteils. Im Hinblick auf einen zügigen und störungsfreien Betrieb der erfindungsgemäßen Durchlaufsägevorrichtung hat es sich jedoch als vorteilhaft erwiesen, dass sie ferner eine Verstelleinrichtung aufweist, mittels der die Sägeelemente entlang der Welle verstellt werden können. Auf diese Weise wird ermöglicht, dass die Sägeelemente und gegebenenfalls auch die Lagerelemente sogar während des Betriebes der Durchlaufsägevorrichtung verstellt werden können. Dabei kann die Verstelleinrichtung beispielsweise manuell-mechanisch arbeiten, z.B. in Form einer mit einer Kurbel versehenen Verstellspindel. Alternativ ist es jedoch im Rahmen der Erfindung ebenso möglich und bevorzugt, dass die Verstelleinrichtung einen Verstellantrieb aufweist, der mit den Sägeelementen und/oder Lagerelementen in Verbindung steht und durch eine Steuereinrichtung steuerbar ist.The adjustment of the respective sawing elements or bearing elements can be done in the context of the present invention in any way, for example, by manual adjustment of each component. In view of a rapid and trouble-free operation of the continuous saw device according to the invention, it has proved to be advantageous, however, that it further comprises an adjusting device by means of which the saw elements can be adjusted along the shaft. In this way it is possible that the sawing elements and possibly also the bearing elements can be adjusted even during operation of the continuous saw device. The adjusting device may, for example, operate manually-mechanically, e.g. in the form of an adjusting spindle provided with a crank. Alternatively, however, it is also possible and preferred within the scope of the invention for the adjusting device to have an adjusting drive which is connected to the sawing elements and / or bearing elements and can be controlled by a control device.
