Description

Die Erfindung betrifft eine Einrichtung nach dem Oberbegriff des Anspruches 1. Eine solche Einrichtung ist der EP 1 889 699 A2 zu entnehmen.The invention relates to a device according to the preamble of claim 1. Such a device is the EP 1 889 699 A2 refer to.

Es ist bekannt, Fehler an Holzwerkstücken zu markieren und anhand der Markierungen die Fehlstellen durch Sägen zu entfernen. Die Abfallteile werden aussortiert, während die Gutteile weitergefördert und sortiert werden. Die hierzu eingesetzte Vorrichtung hat vor und hinter der Trennvorrichtung Vorschubelemente in Form von Vorschubrollen, die das Werkstück vor und hinter der Trennvorrichtung erfassen und während des Sägevorganges festhalten. In Transportrichtung der Werkstücke hinter der der Trennvorrichtung nachgeschalteten Vorschubrolle befindet sich wenigstens eine Beschleunigungsrolle, mit der das gesägte, ein Gutteil bildendes Werkstückteil weitertransportiert wird. Da sich zwischen der Beschleunigungsrolle und der Trennvorrichtung die Vorschubrolle befindet, können nur lange, abgesägte Gutteile von der Beschleunigungsrolle erfasst und beschleunigt weitertransportiert werden. Bei kleinerer Länge müssen die abgesägten Gutteile zunächst durch die nachgeschaltete Vorschubrolle weitertransportiert werden, bis sie in den Bereich der Beschleunigungsrolle gelangen. Erst dann können diese kurzen Gutteile beschleunigt weitertransportiert werden. Der Abstand zwischen Beschleunigungsrolle und der Trennvorrichtung ist groß, weil die Vorschubrolle einen verhältnismäßig großen Durchmesser hat. Aufgrund dieser Ausbildung hat diese bekannte Vorrichtung nur ein begrenztes Leistungsvermögen.It is known to mark defects on wooden workpieces and to remove the defects by sawing based on the markings. The waste parts are sorted out, while the good parts are further promoted and sorted. The device used for this purpose has in front of and behind the separator advancing elements in the form of feed rollers that detect the workpiece in front of and behind the separator and hold during the sawing process. In the transport direction of the workpieces behind the feed roller connected downstream of the separating device, there is at least one acceleration roller with which the sawed, a good part forming workpiece part is transported further. Since the feed roller is located between the acceleration roller and the separating device, only long, sawed-off good parts can be picked up by the acceleration roller and accelerated onward. If the length is shorter, the sawed-off good parts must first be transported further through the downstream feed roller until they reach the area of the acceleration roller. Only then can these short good parts be transported further accelerated. The distance between the acceleration roller and the separator is large because the feed roller has a relatively large diameter. by virtue of This training has this known device only a limited performance.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Vorrichtung so auszubilden, dass sie eine hohe Leistung aufweist.The invention has the object of providing the generic device in such a way that it has a high performance.

Diese Aufgabe wird bei der gattungsgemäßen Vorrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved in the generic device according to the invention with the characterizing features of claim 1.

Bei der erfindungsgemäßen Vorrichtung liegt die Beschleunigungsrolle mit nur sehr geringem Abstand hinter der Trennvorrichtung, da zwischen ihr und der Beschleunigungsrolle kein Vorschubelement vorgesehen ist. Dadurch kann die Beschleunigungsrolle mit nur sehr geringem Abstand in Transportrichtung hinter der Trennvorrichtung angeordnet werden. Dies hat den Vorteil, dass auch sehr kurze, abgesägte Gutteile von der Beschleunigungsrolle erfasst und sofort nach dem Trennvorgang beschleunigt abtransportiert werden können. Die erfindungsgemäße Vorrichtung zeichnet sich darum durch einen sehr hohen Durchsatz aus. Da auch sehr kurze, abgesägte Gutteile von der Beschleunigungsrolle erfasst werden, lassen sich die abgesägten Gutteile unabhängig von ihrer Länge einwandfrei erfassen und zuverlässig durch die erfindungsgemäße Vorrichtung transportieren.In the apparatus according to the invention, the acceleration roller is located behind the separating device with only a very small distance, since no advancing element is provided between it and the acceleration roller. As a result, the acceleration roller can be arranged with only a very small distance in the transport direction behind the separating device. This has the advantage that even very short, sawn-good parts can be detected by the acceleration roller and transported away immediately after the separation process accelerated. The device according to the invention is therefore characterized by a very high throughput. Since even very short, sawed good parts are detected by the acceleration roller, the sawed good parts can be detected regardless of their length properly and reliably transported by the device according to the invention.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of the invention will become apparent from the other claims, the description and the drawings.

Die Vorrichtung dient zum Aussortieren von Abfallteilen von Werkstücken an Sägen. Die Vorrichtung hat eine Transporteinrichtung, die im Ausführungsbeispiel nebeneinander liegende Transportrollen 4 aufweist, die um horizontale Achsen drehbar sind. Die Transportrollen 4 können frei drehbar, aber auch angetrieben sein. Die zu sägenden Werkstücke 2 liegen auf den Transportrollen 4 auf und sind durch Vorschubrollen 6, 11, 12 belastet, die ebenfalls um horizontale Achsen drehbar sind und auf den Werkstücken 2 aufliegen. Die Vorschubrollen 6, 11, 12 sind vorteilhaft höhenverstellbar, so dass sie auf unterschiedliche dicke Werkstücke 2 eingestellt werden können. Die Vorschubrollen 6, 11, 12 können durch einen gemeinsamen Antrieb oder auch unabhängig voneinander drehbar angetrieben sein. Vorteilhaft lassen sich die Vorschubrollen 6, 11, 12 unabhängig voneinander in der Höhe verstellen, so dass sie zuverlässig auf dem zu transportierenden Werkstück 2 aufliegen. Das Werkstück 2 wird auf diese Weise einwandfrei auf der Förderbahn 1 einer Säge 3 zugeführt.The device is used to sort out waste parts of workpieces on saws. The device has a transport device, which in the exemplary embodiment has adjacent transport rollers 4, which are rotatable about horizontal axes. The transport rollers 4 can be freely rotatable, but also driven. The workpieces 2 to be sawed rest on the transport rollers 4 and are loaded by feed rollers 6, 11, 12, which are likewise rotatable about horizontal axes and rest on the workpieces 2. The feed rollers 6, 11, 12 are advantageously adjustable in height, so that they can be adjusted to different thick workpieces 2. The feed rollers 6, 11, 12 can be rotatably driven by a common drive or independently. Advantageously, the feed rollers 6, 11, 12 can be independently adjusted in height, so that they rest reliably on the workpiece 2 to be transported. The workpiece 2 is fed in this way properly on the conveyor track 1 of a saw 3.

Die Vorschubrollen 6, 11, 12 sind nur beispielhaft für eine Vorschubeinrichtung dargestellt und beschrieben. Als Vorschubeinrichtung kommen auch Transportbänder bzw. Transportriemen oder Schiebersysteme in Betracht.The feed rollers 6, 11, 12 are shown and described by way of example only for a feed device. As a feed device and conveyor belts or conveyor belts or slide systems come into consideration.

Anstelle der Vorschubrolle 11 kann ein Messrad eingesetzt werden, das wie die Vorschubrollen um eine horizontale Achse drehbar ist. Das Messrad hat vorteilhaft größeren Durchmesser als die Vorschubrollen 6, 12 und wird nicht motorisch angetrieben, sondern durch seine Berührung mit dem Werkstück 2 um seine horizontale Achse gedreht.Instead of the feed roller 11, a measuring wheel can be used which, like the feed rollers, is rotatable about a horizontal axis. The measuring wheel advantageously has larger diameter than the feed rollers 6, 12 and is not driven by a motor, but rotated by its contact with the workpiece 2 about its horizontal axis.

Die Säge 3 hat wenigstens ein Kreissägeblatt 30, das im Ausführungsbeispiel während des Sägevorganges von unten nach oben in vertikaler Richtung verfahren wird. Das Kreissägeblatt 30 taucht hierbei in ein Gehäuse 10 ein, das sich in einem solchen Abstand oberhalb der Förderbahn 1 befindet, dass sich das Werkstück 2 unter dem Gehäuse 10 hindurch bewegen kann.The saw 3 has at least one circular saw blade 30, which is moved in the embodiment during the sawing process from bottom to top in the vertical direction. The circular saw blade 30 dips into a housing 10 a, which is located at such a distance above the conveyor track 1, that the workpiece 2 can move under the housing 10 therethrough.

In Transportrichtung der Werkstücke 2 hinter der Säge 3 befindet sich wenigstens ein Niederhalter 14, der die gesägten Werkstücke 2 beim Abtransport durch eine Transportvorrichtung 15 niederhält. Sie wird vorteilhaft durch ein endlos umlaufendes Sortierband gebildet. Wie Fig. 2 zeigt, ist das der Säge 3 zugewandte Ende 31 schräg aufwärts gerichtet, so dass die gesägten Werkstücke 2' zuverlässig unter den Niederhalter 14 gelangen. Er ist an einer Tragvorrichtung 16 vorgesehen, die vorteilhaft in Höhenrichtung verstellbar vorgesehen ist. Dadurch lässt sich der Niederhalter 14 optimal auf die Dicke der zu transportierenden Werkstücke 2' einstellen.In the transport direction of the workpieces 2 behind the saw 3 is at least one hold-down 14 which holds down the sawn workpieces 2 during removal by a transport device 15. It is advantageously formed by an endless circulating sorting belt. As Fig. 2 shows, the saw 3 facing the end 31 is directed obliquely upward, so that the sawed workpieces 2 'reach reliably under the hold-down 14. It is provided on a support device 16, which is advantageously provided adjustable in height direction. As a result, the hold-down 14 can be optimally adjusted to the thickness of the workpieces 2 'to be transported.

An der Tragvorrichtung 16 sind im dargestellten Ausführungsbeispiel zwei Niederhalter 14 angeordnet, die in Transportrichtung des gesägten Werkstückes 2' hintereinander angeordnet sind. Dadurch werden die Werkstücke 2' über eine ausreichende Länge zuverlässig gegen die Transportvorrichtung 15 niedergehalten.On the support device 16, two hold-down 14 are arranged in the illustrated embodiment, which are arranged in the transport direction of the sawn workpiece 2 'one behind the other. As a result, the workpieces 2 'are held down reliably against the transport device 15 over a sufficient length.

Die Tragvorrichtung 16 ist mit wenigstens einer, im Ausführungsbeispiel mit zwei Beschleunigungsrollen 17, 18 versehen, die um horizontale Achsen drehbar sind. Sie sind vorteilhaft unabhängig voneinander in der Höhe einstellbar, so dass sie auf unterschiedlich dicke gesägte Werkstücke 2' eingestellt werden können. Zur Höhenverstellung der Beschleunigungsrollen 17, 18 sind an der Tragvorrichtung 16 Stellzylinder 19, 20 vorgesehen, mit denen die Beschleunigungsrollen 17, 18 auf die gesägten Werkstücke 2' gedrückt werden können, wodurch diese unmittelbar nach dem Sägevorgang auf die Transportvorrichtung 15 gedrückt werden. Dadurch ist sichergestellt, dass die gesägten Werkstücke 2' rasch und zuverlässig aus dem Bereich der Säge 3 weitertransportiert werden. Für den Durchtritt der Beschleunigungsrollen 17, 18 ist der Niederhalter 14 mit wenigstens einer Öffnung versehen.The support device 16 is provided with at least one, in the embodiment with two acceleration rollers 17, 18 which are rotatable about horizontal axes. They are advantageously independently adjustable in height so that they can be set to different thickness sawn workpieces 2 '. To adjust the height of the acceleration rollers 17, 18 16 actuating cylinders 19, 20 are provided with which the acceleration rollers 17, 18 can be pressed onto the sawn workpieces 2 'on the support device, whereby they are pressed immediately after the sawing operation on the transport device 15. This ensures that the sawn workpieces 2 'are transported quickly and reliably out of the area of the saw 3. For the passage of the acceleration rollers 17, 18 of the hold-down 14 is provided with at least one opening.

Die beiden Beschleunigungsrollen 17, 18 haben vorteilhaft gleichen Durchmesser, der kleiner ist als der Durchmesser der Vorschubrollen 6, 11, 12. Die Beschleunigungsrolle 18 hat nur geringen Abstand von der Säge 3 bzw. vom Kreissägeblatt 30. Dieser Abstand ist im Ausführungsbeispiel höchstens etwa dem Durchmesser der Beschleunigungsrolle 18. Dieser Abstand kann auch geringer oder größer sein.The two acceleration rollers 17, 18 advantageously have the same diameter, which is smaller than the diameter of the feed rollers 6, 11, 12. The acceleration roller 18 has only a small distance from the saw 3 and the circular saw blade 30. This distance is in the embodiment at most about Diameter of the acceleration roller 18. This distance can also be smaller or larger.

Anhand der Fig. 2 bis 5 wird beispielhaft der Verfahrensablauf erläutert. Der Transporteinrichtung 6, 11, 12 ist eine (nicht dargestellte) Zuführeinrichtung vorgeschaltet, auf der die Werkstücke 2 zugeführt werden. Sie werden zunächst von der Vorschubrolle 6 erfasst, die die Werkstücke 2 den nachfolgenden Vorschubrollen 11, 12 zuführt. Sie sind drehbar angetrieben und transportieren das Werkstück 2 in Richtung auf die Säge 3.Based on Fig. 2 to 5 the procedure is explained by way of example. The transport device 6, 11, 12 is preceded by a feed device (not shown), on which the workpieces 2 are fed. They are first detected by the feed roller 6, which feeds the workpieces 2 to the subsequent feed rollers 11, 12. They are rotatably driven and transport the workpiece 2 in the direction of the saw. 3

Damit das Werkstück 2 an der richtigen Stelle gesägt wird, sind am Werkstück 2 Markierungen vorgesehen, welche die Schnittposition des Werkstückes 2 an der Säge 3 festlegen. Anstelle der manuellen Markierungen können die Werkstücke 2 auch durch Sensoren, Kameras und dergleichen auf Fehler überprüft werden, die durch den Sägevorgang entfernt werden müssen. Diese Markierungen werden in einen Speicher eines Rechners abgelegt, der anhand dieser Schnittliste rechnergesteuert die Werkstücke 2 an der richtigen Stelle anhält, so dass die Säge 3 den erforderlichen Sägeschnitt ausführen kann.In order for the workpiece 2 to be sawn at the correct position, markings are provided on the workpiece 2 which define the cutting position of the workpiece 2 on the saw 3. Instead of the manual markings, the workpieces 2 can also be checked for errors by sensors, cameras and the like, which must be removed by the sawing process. These markings are stored in a memory of a computer, which stops the workpieces 2 at the correct location on the basis of this list of cuts, so that the saw 3 can execute the required saw cut.

Sobald sich die Schnittmarkierung in der Säge 3 an der richtigen Stelle befindet, wird der Antrieb der Vorschubrollen 6, 11, 12 gestoppt. Anschließend wird das Kreissägeblatt 30 von unten nach oben bewegt und das Werkstück 2 an der markierten Stelle gesägt.As soon as the cutting mark in the saw 3 is in the correct position, the drive of the feed rollers 6, 11, 12 is stopped. Subsequently, the circular saw blade 30 is moved from bottom to top and sawed the workpiece 2 at the marked location.

Bereits bei Erreichen der obersten Position des Kreissägeblattes 30, also sobald das Werkstück 2 durchtrennt ist, wird mit der Separierung des abgetrennten Werkstückteiles vom restlichen, noch von den Vorschubrollen erfassten Werkstückteil begonnen.Already on reaching the uppermost position of the circular saw blade 30, so as soon as the workpiece 2 is severed, is started with the separation of the separated workpiece part from the rest, still detected by the feed rollers workpiece part.

Fig. 2 zeigt den Fall, dass das abgetrennte Werkstück 2', das beispielhaft ein Gutteil ist, nur eine geringe Länge hat. Mit dem Stellzylinder 20 wird die Beschleunigungsrolle 18 so weit abgesenkt, dass sie auf dem gesägten Werkstück 2' aufliegt und dieses auf das endlos umlaufende Sortierband 15 drückt, wodurch dieses in Transportrichtung beschleunigt wird. Der Druck auf das Werkstück 2' wird gerade so hoch eingestellt, dass es vom kontinuierlich angetriebenen Sortierband 15 sicher erfasst wird. Fig. 2 shows the case that the severed workpiece 2 ', which is a good example by way of example, has only a small length. With the actuating cylinder 20, the acceleration roller 18 is lowered so far that it rests on the sawn workpiece 2 'and this presses on the endless circulating sorting belt 15, whereby this is accelerated in the transport direction. The pressure on the workpiece 2 'is just set so high that it is reliably detected by the continuously driven sorting belt 15.

Das kontinuierlich umlaufende Sortierband 15 kann eine Geschwindigkeit beispielsweise bis zu 250 m/min aufweisen, so dass eine ausreichend hohe Beschleunigung des gesägten Werkstückes 2' erreicht werden kann. Aufgrund der gezielten Beschleunigung des Werkstückes 2' hängt die Zeit bis zur Mitnahme des Werkstückes 2' vom Sortierband 15 nicht von Reibfaktoren, wie Teilegewicht, Oberflächenstruktur und dergleichen, ab.The continuously circulating sorting belt 15 may have a speed, for example, up to 250 m / min, so that a sufficiently high acceleration of the sawn workpiece 2 'can be achieved. Due to the targeted acceleration of the workpiece 2 ', the time to take the workpiece 2' from the sorting belt 15 does not depend on friction factors, such as part weight, surface structure and the like.

Das Sortierband 15 wird über Umlenkrollen 22 geführt, von denen in Fig. 3 nur die der Säge 3 benachbarte Umlenkrolle 22 dargestellt ist. Diese Umlenkrolle 22 kann in Transportrichtung der Werkstücke 2' verstellt werden. Dadurch kann ein Abfallschacht 21 geöffnet und geschlossen werden. Ist das gesägte Werkstück 2' ein Abfallstück, dann wird der Abfallschacht 21 geöffnet, so dass das Abfallstück nach unten in den Abfallschacht 21 fallen kann. Aufgrund der Verstellbarkeit der Umlenkrollen 22 kann der Abfallschacht 21 teilweise oder ganz geöffnet werden.The sorting belt 15 is guided over deflection rollers 22, of which in Fig. 3 only the saw 3 adjacent guide roller 22 is shown. This guide roller 22 can be adjusted in the transport direction of the workpieces 2 '. As a result, a waste chute 21 can be opened and closed. If the sawn workpiece 2 'is a waste piece, then the waste chute 21 is opened so that the waste piece can fall down into the waste chute 21. Due to the adjustability of the deflection rollers 22, the waste chute 21 can be opened partially or completely.

Mit dem Sortierband 15 werden die gesägten Werkstücke 2' weitertransportiert, insbesondere einer Sortiereinrichtung zugeführt, mit der diese Werkstücke 2' unter Berücksichtigung ihrer Länge sortiert werden.With the sorting belt 15, the sawn workpieces 2 'are transported further, in particular fed to a sorting device, with which these workpieces 2' are sorted taking into account their length.

In der Stellung gemäß Fig. 2 ist der Abfallschacht 21 geschlossen, das heißt die Vorschubrollen 22 sind am weitesten in Richtung auf die Säge 3 verstellt.In the position according to Fig. 2 the waste chute 21 is closed, that is, the feed rollers 22 are moved furthest in the direction of the saw 3.

Fig. 3 zeigt den Fall, dass der Abfallschacht 21 teilweise geöffnet ist, indem die entsprechenden Umlenkrollen 22 für das Sortierband 15 zurückbewegt worden sind. Die Verfahrbewegung der Umlenkrollen 22 kann schon vor dem Sägevorgang erfolgen, da vor dem Einlaufen des Werkstückes 2 in die Säge 3 die Schnittpositionen, an denen gesägt werden muss, in die Steuerung eingelesen worden sind. Anhand dieser eingelesenen Daten können die entsprechenden Verstellungen der Maschinenteile vorgenommen werden. Fig. 3 zeigt den Fall, dass das abgesägte Werkstück 2' länger ist als beim Ausführungsbeispiel nach Fig. 2. Das Werkstück 2' ist so lang, dass es trotz teilweise geöffnetem Abfallschacht 21 auf das Sortierband 15 gelangt und nicht in den Abfallschacht 21 fällt. Aufgrund der größeren Länge des Werkstückes 2' wird die von der Säge 3 entfernt liegende Beschleunigungsrolle 17 mittels des Stellzylinders 19 auf das Werkstück 2' gedrückt, das vom Sortierband 15 mitgenommen und in der beschriebenen Weise gezielt beschleunigt wird. Fig. 3 shows the case that the refuse chute 21 is partially opened by the corresponding guide rollers 22 have been moved back for the sorting belt 15. The movement of the guide rollers 22 can be done before the sawing process, as before the shrinkage of the workpiece 2 in the saw 3, the cutting positions at which must be sawn, have been read into the controller. On the basis of this read data, the corresponding adjustments of the machine parts can be made. Fig. 3 shows the case that the sawn workpiece 2 'is longer than in the embodiment according to Fig. 2 , The workpiece 2 'is so long that, despite partially opened waste chute 21, it reaches the sorting belt 15 and does not fall into the waste chute 21. Due to the greater length of the workpiece 2 ', the accelerator roller 17 remote from the saw 3 is pressed by means of the adjusting cylinder 19 onto the workpiece 2', which is carried along by the sorting belt 15 and selectively accelerated in the manner described.

Fig. 4 zeigt den Fall, dass an der Säge 3 ein Abfallteil 2" abgesägt wird, das eine Fehlstelle enthält. Nachdem das Werkstück 2 mittels der Vorschubrollen 6, 11, 12 gegenüber der Säge 3 positioniert worden ist, wird der Abfallteil 2" abgesägt. Er fällt, nachdem das Sägeblatt 30 seine oberste Position erreicht hat, sofort nach unten in den teilweise geöffneten Abfallschacht 21. Das Sortierband 15 mit den Umlenkrollen 22 ist so weit zurückgefahren, dass der Abfallteil 2" einwandfrei in den Abfallschacht 21 fallen kann. Fig. 4 shows the case where a waste part 2 "containing a defect is sawed off at the saw 3. After the work piece 2 has been positioned against the saw 3 by means of the feed rollers 6, 11, 12, the waste part 2" is sawn off. It falls after the saw blade 30 has reached its uppermost position, immediately down into the partially open waste chute 21. The sorting belt 15 with the pulleys 22 is moved back so far that the waste part 2 "can fall properly into the refuse chute 21.

Dem Abfallschacht 21 ist zur Unterstützung der Fallbewegung der Abfallteile 2" vorteilhaft zusätzlich mindestens ein (nicht dargestelltes) Beschleunigungselement, wie eine Blasdüse oder ein Stößel, zugeordnet. Wird beispielhaft eine Blasdüse eingesetzt, wird sie vorteilhaft am Niederhalter 14 vorgesehen. Hat die Vorrichtung nur eine Beschleunigungsrolle, dann befindet sich die Blasdüse vorteilhaft im Bereich zwischen dem Kreissägeblatt 30 und dieser Beschleunigungsrolle. Sind am Niederhalter 14, wie im dargestellten Ausführungsbeispiel, zwei Beschleunigungsrollen 17, 18 vorhanden, dann befindet sich die Blasdüse vorteilhaft im Bereich zwischen den beiden Beschleunigungsrollen 17 und 18.Advantageously, at least one acceleration element (not shown), such as a tuyere or a tappet, is associated with the waste chute 21 in support of the falling movement of the waste parts 2. If, for example, a tuyere is used, it is advantageously provided on the hold-down 14. If the device has only one Acceleration roller, then the tuyere is advantageously in the area between the circular saw blade 30 and this acceleration roller., Are on the hold-down 14, as in the illustrated embodiment, two acceleration rollers 17, 18, then the tuyere is advantageously in the region between the two acceleration rollers 17 and 18th

Sobald der Abfallteil 2" nach unten gefallen ist, werden die Umlenkrollen 22 in Richtung auf die Säge 3 verfahren und damit der Abfallschacht 21 geschlossen, so dass unmittelbar anschließend mit den Vorschubrollen 6, 11, 12 das Werkstück 2 weitertransportiert werden kann. Gegebenenfalls wird das Werkstück 2 an einer markierten Stelle erneut angehalten, um einen Sägeschnitt vorzunehmen.As soon as the waste part 2 "has fallen down, the deflection rollers 22 are moved in the direction of the saw 3 and thus the waste chute 21 is closed so that the workpiece 2 can be transported further immediately afterward with the feed rollers 6, 11, 12 Workpiece 2 at a marked point stopped again to make a saw cut.

Fig. 5 zeigt den Fall, dass der Abfallteil 2" eine größere Länge hat. Dementsprechend muss das Sortierband 15 mit den Umlenkrollen 22 weiter von der Säge 3 zurückgefahren werden, um den Abfallschacht 21 weiter zu öffnen. Der längere Abfallteil 2" kann dann nach dem Sägevorgang problemlos in den Abfallschacht 21 fallen. Fig. 5 shows the case that the waste part 2 "has a greater length, Accordingly, the sorting belt 15 with the pulleys 22 must be moved further back from the saw 3 to further open the waste chute 21. The longer waste part 2" can then be easily after the sawing operation fall into the garbage chute 21.

Da die Gutteile 2' nach dem Sägeschnitt mittels der Beschleunigungsrollen 17, 18 beschleunigt werden, kann der Abfallschacht 21 sehr früh geöffnet werden, ohne dass die Gefahr besteht, dass das Gutteil 2' versehentlich in den Abfallschacht 21 fällt.Since the good parts 2 'are accelerated after the saw cut by means of the acceleration rollers 17, 18, the waste chute 21 can be opened very early without the risk that the good part 2' accidentally falls into the waste chute 21.

Der Abfallteil 2" kann bereits nach der Aufwärtsbewegung des Sägeblattes 30 in den Abfallschacht 21 fallen, wodurch die Umlenkrollen 22 des Sortierbandes 15 früher positioniert werden können, um den Abfallschacht 21 zu schließen, falls dies durch ein darauffolgendes kurzes Gutteil 2' nötig wäre. Der Abfallschacht 21 wird stets nur so weit geöffnet, wie es zur Entsorgung des Abfallteiles 2" erforderlich ist.The waste part 2 "can already fall into the waste chute 21 after the upward movement of the saw blade 30, whereby the guide rollers 22 of the sorting belt 15 can be positioned earlier to close the waste chute 21, if this would be necessary by a subsequent short good part 2 ' Garbage chute 21 is always opened only as far as it is necessary to dispose of the waste part 2 ".

Je nach Länge des nachfolgend zu sägenden Gutteiles 2' kann der Abfallschacht 21 geöffnet bleiben. Dies ist beispielsweise dann der Fall, wenn das nachfolgend zu sägende Gutteil 2' so lang ist, dass es trotz geöffnetem Abfallschacht 21 mit seinem in Transportrichtung vorderen Ende auf das Sortierband 15 gelangt und von den Beschleunigungsrollen 17, 18 auf das Sortierband 15 gedrückt und sofort nach dem Schnitt über den Öffnungsbereich des Abfallschachtes 21 hinweg beschleunigt weitertransportiert wird.Depending on the length of the following to be sawn Good part 2 ', the refuse chute 21 remain open. This is the case, for example, when the good part 2 'to be subsequently sawed is so long that it reaches the sorting belt 15 with its forward end in the direction of transport, despite the waste chute 21 being open, and the sorting belt 17, 18 Pressed 15 and immediately after the cut across the opening portion of the refuse chute 21 away accelerated away.

Die Beschleunigungsrollen 17, 18 werden von den Stellzylindern 19, 20 bei jedem Gutteil 2' nach unten bewegt und auf das Gutteil 2' gedrückt. Unmittelbar anschließend fahren die Stellzylinder 19, 20 die Beschleunigungsrollen 17, 18 zurück, so dass der nachfolgende Gutteil 2' zuverlässig unter die Niederhalter 14 gelangen kann.The acceleration rollers 17, 18 are moved by the adjusting cylinders 19, 20 in each good part 2 'down and pressed on the Good part 2'. Immediately thereafter, the actuating cylinders 19, 20 drive back the acceleration rollers 17, 18, so that the following good part 2 'can reliably reach under the downholders 14.

Am Niederhalter 14 kann auch nur eine Beschleunigungsrolle vorgesehen sein, mit der die entsprechenden Gutteile 2' auf das Sortierband 15 gedrückt werden können. Der Einsatz von zwei oder auch mehr in Transportrichtung mit Abstand hintereinander liegenden Beschleunigungsrollen hat den Vorteil, dass unterschiedlich lange Gutteile 2' innerhalb kürzester Zeit beschleunigt werden können. Das Verfahren der Umlenkrollen 22 des Sortierbandes 15 erfolgt vorteilhaft mittels eines Servomotors, mit dem das Sortierband 15 bzw. seine entsprechende Umlenkrolle 22 zum Öffnen und Schließen des Abfallschachtes 21 positioniert werden kann.At the hold-down 14, only one acceleration roller can be provided, with which the corresponding good parts 2 'can be pressed onto the sorting belt 15. The use of two or even more in the transport direction with distance succession acceleration rollers has the advantage that different lengths good parts 2 'can be accelerated within a very short time. The method of the deflection rollers 22 of the sorting belt 15 is advantageously carried out by means of a servo motor, with which the sorting belt 15 and its corresponding guide roller 22 for opening and closing the waste chute 21 can be positioned.

Mit der Vorrichtung ist es möglich, mit hoher Geschwindigkeit Werkstücke 2 zu sägen, Abfallteile auszusortieren und die Gutteile zu sortieren.With the device, it is possible to saw workpieces 2 at high speed, sort out waste parts and sort the good parts.

Das Sägeblatt 30 der Säge 3 wird im Ausführungsbeispiel beim Sägeschnitt von unten nach oben bewegt. Ebenso ist es möglich, das Sägeblatt von oben nach unten oder zur Seite hin beim Sägeschnitt zu bewegen.The saw blade 30 of the saw 3 is moved in the embodiment of the saw cut from bottom to top. It is also possible to move the saw blade from top to bottom or to the side at the saw cut.

Die Werkstücke 2 lassen sich außer durch Sägen auch durch andere Schneideverfahren abschneiden, beispielsweise mit Hilfe von Lasern, Wasserstrahl und dergleichen.The workpieces 2 can be cut off except by sawing by other cutting methods, for example with the aid of lasers, water jet and the like.
