They are swivelled on a vertical pivot axle (32) positioned on the end of the rail facing the separating line (16) of the plate cutting saw (12). At least the roller rail next to the straight stop member (30) is fixed. The roller rails swivelable into a cutting position are positioned on a flap behind the plate-cutting saw. <IMAGE>

Description

Die Erfindung betrifft eine Einrichtung zum Trennen von aneinander anliegenden, quergeteilten Plattenstreifen hinter der Trennlinie von Plattenaufteilsägen, mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a device for separating adjacent, cross-divided panel strips behind the dividing line of panel sizing saws, with the features of the preamble of claim 1.

Für das Buntaufteilen von Werkstückplatten sind auf einer Plattenaufteilsäge zwei Aufteiloperationen durchzuführen. Im Verlaufe einer ersten Aufteiloperation sind Werkstückplatten zunächst in einzelne, streifenförmige Plattenteile bzw. Plattenstreifen aufzuteilen. Anschliessend sind diese, in einer um 90° gedrehten Lage und Kante an Kante liegend, in einer zweiten Aufteiloperation nochmals mittels der Plattenaufteilsäge in Querrichtung aufzuteilen.For the colorful division of workpiece plates, two division operations are to be carried out on a plate dividing saw. In the course of a first dividing operation, workpiece plates must first be divided into individual, strip-shaped plate parts or plate strips. Then, in a position rotated by 90 ° and lying edge to edge, these are to be divided in a second dividing operation again using the panel dividing saw in the transverse direction.

Um nun als Ergebnis des Buntaufteilens bzw. nach der zweiten Aufteiloperation Plattenformate mit gewünschten, unterschiedlichen Abmessungen zu erhalten, werden hierfür die einzelnen, aneinander anliegenden Plattenstreifen vor jedem durchzuführenden Trennschnitt mittels einer Vorschubvorrichtung in Vorschubrichtung jeweils um unterschiedliche Vorschubwege verschoben und dann vor dem Durchtrennen auf dem Maschinentisch vor der Schnittlinie gemeinsam festgelegt.In order to obtain plate formats with the desired, different dimensions as a result of the slicing or after the second slicing operation, the individual, adjacent plate strips are shifted by a feed device in the feed direction by different feed paths before each cut and then before cutting on the Machine table defined in front of the cutting line.

Das Verschieben der aneinander anliegenden, aufgeteilten Plattenstreifen relativ zueinander schafft insofern Probleme, als die nach der Schnittlinie anfallenden, unterschiedlichen Plattenformate entlang ihren einander berührenden Trennkanten, aufgrund ihrer durch den Trennschnitt entstandenen, verhältnismässig rauhen Oberfläche miteinander verhaken können, woraus wiederum ein Mitschleppeffekt resultieren kann. Ausserdem können Plattenformate während ihrer Vorschubbewegung ggf. verdreht werden.Moving the adjoining, divided plate strips relative to one another creates problems in that the different plate formats occurring along the cutting line along their contacting separating edges can get caught together due to the relatively rough surface created by the separating cut, which in turn can result in a drag effect. In addition, plate formats can possibly be rotated during their feed movement.

Ein geordneter Weitertransport ist deshalb kaum zu gewährleisten.An orderly onward transport can therefore hardly be guaranteed.

Es ist bereits eine Einrichtung zum Ausserberührungbringen von aneinander anliegenden, aufgeteilten Plattenstreifen in einer Ausbildung gemäss dem Oberbegriff des Anspruches 1 bekannt.There is already known a device for bringing out of contact with adjacent, divided plate strips in an embodiment according to the preamble of claim 1.

Bei dieser Konstruktion sind sowohl stationäre als auch anheb- und absenkbare Rollenschienen (Hubschienen) vorgesehen. Dabei ist die Achse der Schienenrollen zur Schienenlängsachse geringfügig schräggestellt.In this construction, both stationary and lifting and lowering roller rails (lifting rails) are provided. The axis of the rail rollers is slightly inclined to the longitudinal axis of the rail.

In der unteren Ausgangsstellung der Hubschienen befinden sich hierbei deren schräggestellte Rollen mit ihrem oberen Umfangsabschnitt geringfügig unterhalb einer durch die Rollen der stationären Rollenschienen definierten, ersten Auflageebene für die anfallenden Plattenformate.In the lower starting position of the lifting rails, their inclined rollers with their upper peripheral section are located slightly below a first support plane for the plate formats that is defined by the rollers of the stationary roller rails.

Für die zweite Aufteiloperation werden dann die Hubschienen so weit angehoben, dass deren Rollen geringfügig die erste Auflageebene überragen bzw. zur Aufnahme der Plattenformate eine zweite Auflageebene definieren.For the second dividing operation, the lifting rails are then raised to such an extent that their rollers slightly protrude beyond the first support level or define a second support level to accommodate the plate formats.

Aufgrund der Schrägstellung der Hubschienenrollen werden dann die Plattenformate bei Vorschubbewegungen in seitlicher Richtung voneinander wegbewegt bzw. getrennt.Due to the inclined position of the lifting rail rollers, the plate formats are then moved or separated from one another during feed movements in the lateral direction.

Diese Konstruktion erfordert somit zwei, jeweils verschiedene Rollenanordnungen aufweisende Gruppen von Rollenschienen mit einer Hubvorrichtung, was herstellungstechnisch aufwendig und entsprechend kostenintensiv ist.This construction thus requires two groups of roller rails, each with different roller arrangements, with a lifting device, which is technically complex and correspondingly cost-intensive.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung in einer Ausbildung gemäss dem Oberbegriff des Anspruches 1 anzugeben, die es ermöglicht, sowohl auf anheb- und absenkbare Rollenschienen als auch auf unterschiedlich positionierte Rollen auf bestimmten Rollenschienen verzichten zu können.The invention has for its object to provide a device in an embodiment according to the preamble of claim 1, which makes it possible to dispense with both lifting and lowering roller rails and differently positioned rollers on certain roller rails.

Diese Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.

Die erfindungsgemässe Konstruktion zeichnet sich somit durch eine einheitliche Ausbildung der Rollenschienen aus, die in einer gemeinsamen Ebene zu installieren sind.The construction according to the invention is thus characterized by a uniform design of the roller rails which are to be installed in a common plane.

Die verschwenkbare Anordnung eines Teils der Rollenschienen und der Horizontalen, aus einer zur Vorschubrichtung einer Plattenaufteilsäge parallelen Lage in eine zu dieser schräg verlaufende Lage erlaubt es zum einen, Plattenstreifen mit aneinander anliegenden Trennkanten, die parallel zur Schnittlinie liegen, bei Einstellung der verschwenkbaren Rollenschienen parallel zur Vorschubrichtung, zu einer Übernahmestation zu fördern, wobei solche Werkstücke ihre relative Lage zueinander exakt beibehalten.The pivotable arrangement of part of the roller rails and the horizontal, from a position parallel to the feed direction of a panel sizing saw into an oblique position to this, on the one hand allows plate strips with mutually adjacent separating edges that are parallel to the cutting line when the pivotable roller rails are set parallel to Feed direction to promote to a transfer station, such workpieces maintain their relative position to each other exactly.

Zum anderen lassen sich beim Buntaufteilen anfallende unterschiedliche Plattenformate durch Verschwenken von Rollenschienen bzw. deren Schrägstellen in der Horizontalen während der Vorschubbewegung in seitlicher Richtung auseinanderbewegen, so dass zwischen benachbarten Plattenformaten ein Trennspalt entsteht und somit ein gegenseitiges Verhaken von Plattenformaten verhindert wird.On the other hand, the different plate formats that occur when dividing colors can be moved apart sideways by swiveling roller rails or their inclines horizontally during the feed movement, so that a separation gap is created between adjacent plate formats and thus prevents the plate formats from getting caught.

Damit das der Plattenaufteilsäge benachbarte Ende der verschwenkbar vorgesehenen Rollenschienen bei deren Schrägstellung seine Lage zur Plattenaufteilsäge im wesentlichen beibehält, ist es günstig, die Schwenkachsen der Rollenschienen gemäss Anspruch 2 vorzusehen.So that the end of the swiveling roller rails adjacent to the panel sizing saw essentially remains in its position relative to the panel sizing saw when it is tilted, it is expedient to provide the pivot axes of the roller rails according to claim 2.

Vorteilhafterweise wird man hierbei mit Ausnahme der dem Winkellineal benachbarten Rollenschiene alle weiteren Rollenschienen verschwenkbar vorsehen (Anspruch 3), so dass sich auch die Plattenformate von umfangreich aufgeteilten Aufteilbildern voneinander trennen lassen.Advantageously, with the exception of the roller rail adjacent to the angular ruler, all other roller rails will be provided so that they can be pivoted (claim 3), so that the plate formats can also be separated from one another by extensively divided division images.

Eine bevorzugte Ausführungsform der Erfindung ist Gegenstand des Anspruches 4. Dadurch ist es möglich, durch entsprechende Wahl des Schienenschwenkwinkels, gewünschte Abstände zwischen benachbarten Plattenformaten einzustellen.A preferred embodiment of the invention is the subject of claim 4. This makes it possible to set the desired distances between adjacent plate formats by appropriate choice of the rail pivot angle.

Ein grosser Vorteil dieser Konstruktion besteht des weiteren darin, die Länge der verschwenkbaren Rollenschienen relativ klein wählen zu können. Dies ermöglicht wiederum eine Anordnung der Rollenschienen gemäss Anspruch 5 und somit die Rollenschienen unmittelbar hinter der Trennlinie beginnen zu lassen. Dadurch lässt sich der wesentliche Vorteil erzielen, dass sich Plattenformate unmittelbar hinter der Trennlinie beim Vorschub nicht verdrehen können.Another great advantage of this construction is that the length of the pivotable roller rails can be chosen to be relatively small. This in turn enables an arrangement of the roller rails according to claim 5 and thus to let the roller rails begin immediately behind the dividing line. The main advantage of this is that plate formats cannot twist immediately behind the dividing line during feed.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Ansprüche 6 - 9.Further advantageous embodiments of the invention are the subject of claims 6-9.

In Fig. 1 bezeichnet 10 als Ganzes die erfindungsgemässe Einrichtung, die einer Plattenaufteilsäge 12 ausgangsseitig zugeordnet ist. Letztere weist einen Sägetisch 14 mit beispielsweise unter Tisch fahrendem Sägeaggregat auf, das einfachtheitshalber nicht dargestellt ist.In FIG. 1, 10 designates as a whole the device according to the invention, that of a panel saw 12 on the output side assigned. The latter has a saw table 14 with, for example, a saw unit traveling under a table, which is not shown for the sake of simplicity.

Der Sägetisch 14 ist in Längsrichtung durch einen eine Trenn- bzw. Sägelinie 16 definierenden Sägeschlitz geteilt, aus dem zur Plattenaufteilung wenigstens ein Kreissägeblatt des Sägeaggregates austaucht.The saw table 14 is divided in the longitudinal direction by a sawing slot defining a dividing or sawing line 16, from which at least one circular saw blade of the saw unit emerges for the panel division.

Die Einrichtung 10 ist als horizontale Verlängerung des Sägetisches 14 zu betrachten und übernimmt von diesem während des Vorschubes einer aufzuteilenden Werkstückplatte beispielsweise zwei oder auch mehrere anfallende Plattenstreifen 18, 20 bzw. in einer weiteren Sägeoperation in einzelne Plattenformate 22 und 24 quer aufgeteilte Plattenstreifen 18, 20, worauf nachstehend noch eingegangen wird.The device 10 is to be regarded as a horizontal extension of the saw table 14 and takes over from it during the advance of a workpiece plate to be divided, for example, two or more plate strips 18, 20 or in a further sawing operation into individual plate formats 22 and 24, transverse plate strips 18, 20 , which will be discussed below.

Die Einrichtung 10 ist mit einer Vielzahl von Rollenschienen 26 gleicher Ausbildung ausgestattet, wobei das vorliegende Ausführungsbeispiel der Erfindung z.B. vier Gruppen a, b, c und d solcher Rollenschienen 26 umfasst. Jede Rollenschiene 26 trägt beispielsweise fünf Paare von in gleicher Horizontalebene gelagerten Tragrollen 28 gleichen Durchmessers.The device 10 is equipped with a plurality of roller rails 26 of the same design, the present exemplary embodiment of the invention e.g. comprises four groups a, b, c and d of such roller rails 26. Each roller rail 26 carries, for example, five pairs of supporting rollers 28 of the same diameter, which are mounted in the same horizontal plane.

Während die in einheitlichem, gegenseitigem Abstand vorgesehenen Rollenschienen 26 der beiden, quer zur Vorschubrichtung, gemäss Pfeil B, einander benachbarten Rollenschienengruppen a und b sich zur Vorschubrichtung und einem sich in gleicher Richtung erstreckenden, maschinenfesten Anschlaglineal 30 parallel erstrecken, sind die Rollenschienen 26 der beiden Rollenschienengruppen c und d jeweils um eine vertikale Schwenkachse 32 aus einer zu den Rollenschienen 26 der Rollenschienengruppe a und b fluchtenden Lage in eine vom Anschlaglineal 30 wegfördernde Schrägstellung (Winkel α) verschwenkbar und in dieser Stellung feststellbar.While the roller rails 26 of the two roller rails groups a and b, which are adjacent to one another and at right angles to one another and at right angles to one another, extend parallel to the feed direction and a machine-fixed stop ruler 30 extending in the same direction, the roller rails 26 are the two Roller rail groups c and d can each be pivoted about a vertical pivot axis 32 from a position aligned with the roller rails 26 of roller rail groups a and b into an inclined position (angle α) which promotes away from the straightedge 30 and can be locked in this position.

Im Falle der Rollenschienengruppe c gilt dies vorzugsweise nicht für die dem Anschlaglineal 30 benachbarte Rollenschiene 26.In the case of the roller rail group c, this preferably does not apply to the roller rail 26 adjacent to the stop ruler 30.

Die gruppenweise Aufteilung der Rollenschienen 26 erlaubt es, die Rollenschienen 26 der sich an die Sägelinie 16 anschliessenden Schienengruppen c und d relativ kurz auszulegen, mit dem Vorzug, diese bei Vorhandensein einer dem Sägetisch 14 nachgeordneten Abfallklappe 34 auf dieser anordnen und damit nahe an der Sägelinie 16 beginnen lassen zu können (s. Fig. 2).The grouping of the roller rails 26 allows the roller rails 26 of the rail groups c and d adjoining the saw line 16 to be designed to be relatively short, with the advantage of arranging them on the saw table 14 in the presence of a waste flap 34 thereon and thus close to the saw line 16 can start (see Fig. 2).

Um hierbei beim Verschwenken der Rollenschienen 26 das der Sägelinie 16 zugekehrte Schienenende möglichst wenig zu verlagern, ist die Schwenkachse 32 diesem Schienenende zugeordnet. Sie ist dabei von der Abfallklappe 34 aufgenommen.In order to shift the rail end facing the saw line 16 as little as possible when pivoting the roller rails 26, the pivot axis 32 is assigned to this rail end. It is received by the waste flap 34.

Die verschwenkbaren Rollenschienen 26 beider Schienengruppen c und d können über eine Verstellvorrichtung gemeinsam in eine übereinstimmende Schrägstellung verschwenkbar sein. Vorzugsweise sind jedoch die Rollenschienen 26 gruppenweise für sich verschwenkbar. Hierzu kann eine Verstellvorrichtung je Schienengruppe vorgesehen sein, wobei die Verstellvorrichtung beliebig ausgebildet sein kann.The pivotable roller rails 26 of both rail groups c and d can be pivoted together into an identical inclined position via an adjusting device. However, the roller rails 26 are preferably pivotable in groups. For this purpose, one adjustment device can be provided for each rail group, wherein the adjustment device can be designed as desired.

Im vorliegenden Falle ist jedoch jeder Rollenschiene 26 eine durch ein doppelt beaufschlagbares, vorzugsweise pneumatisch betätigbares Zylinderaggregat 36 gebildete Verstellvorrichtung zugeordnet, wobei die Zylinderaggregate 36 in Reihe geschaltet bzw. an einer gemeinsamen Druckluftleitung 38 angeschlossen sind.In the present case, however, each roller rail 26 is assigned an adjustment device formed by a double-acting, preferably pneumatically actuatable cylinder unit 36, the cylinder units 36 being connected in series or connected to a common compressed air line 38.

Die Einrichtung arbeitet zum Buntaufteilen von Werkstückplatten folgendermassen:The device works for the color division of workpiece plates as follows:

In einer ersten Aufteiloperation werden z.B. rechteckförmige Werkstückplatten parallel zu ihrer Längsrichtung in einzelne Plattenstreifen 18, 20 aufgeteilt, die in der Breite unterschiedlich sein können.In a first splitting operation e.g. rectangular workpiece plates parallel to their longitudinal direction divided into individual plate strips 18, 20, which can be different in width.

Die anfallenden, zum Anschlaglineal 30 parallelen Plattenstreifen 18, 20 gelangen während des Plattenvorschubes auf die Rollenschienen 26. Die veschwenkbaren Schienengruppen c und d sind dabei derart einzustellen, dass ihre Rollenschienen 26 zu denjenigen der beiden Rollenschienengruppen a und b fluchten. Dadurch ist sichergestellt, dass die Plattenstreifen 18, 20 während des Vorschubes ihre relative Lage zueinander beibehalten.The resulting plate strips 18, 20 parallel to the stop ruler 30 reach the roller rails 26 during the plate advance. The pivotable rail groups c and d are to be adjusted such that their roller rails 26 are aligned with those of the two roller rail groups a and b. This ensures that the plate strips 18, 20 maintain their relative position to one another during the feed.

Nach Abschluss der ersten Aufteiloperation werden die Plattenstreifen 18, 20 um 90° versetzt weitertransportiert und dabei, erneut nebeneinanderliegend, in einer zweiten Aufteiloperation quer zu ihrer Längsrichtung in unterschiedliche Plattenformate 22 bzw. 24 aufgeteilt.After the first splitting operation has been completed, the plate strips 18, 20 are transported further offset by 90 ° and, again lying side by side, are divided into different plate formats 22 and 24 in a second splitting operation transverse to their longitudinal direction.

Für diese zweite Aufteiloperation sind die einzelnen Plattenstreifen 18, 20 vor jedem Trennschnitt in bekannter Weise um unterschiedliche Wege in Vorschubrichtung B und C zu verschieben. Ausserdem sind die die Einzelformate 24 des Plattenstreifens 20 aufnehmenden Rollenschienen 26 der Schienengruppe d, wie in Fig. 1 gezeigt, um einen Winkel α um die Schwenkachse 32 derart zu verschwenken, dass die einzeln anfallenden Plattenformate 24 von den Plattenformaten 22 des quer aufgeteilten Plattenstreifens 18 zunächst in seitlicher Richtung, gemäss Fig. 1 nach rechts, um einen Betrag e wegbewegt und anschliessend durch deren Übernahme durch die Schienengruppe b wieder parallel zu den Plattenformaten 22 in Vorschubrichtung C weiterbewegt werden.For this second dividing operation, the individual plate strips 18, 20 are to be moved in a known manner by different paths in the feed direction B and C before each separating cut. In addition, as shown in FIG. 1, the roller rails 26 of the rail group d that receive the individual formats 24 of the plate strip 20 are pivoted by an angle α about the pivot axis 32 such that the individually occurring plate formats 24 differ from the plate formats 22 of the transversely divided plate strip 18 first in the lateral direction, according to FIG. 1 to the right, moved away by an amount e and then by taking it over through the rail group b again in parallel to the plate formats 22 in the feed direction C.

Wie Fig. 2 zeigt, können auf diese Weise auch gestapelte Werkstückplatten buntaufgeteilt werden. Die Verschwenkbarkeit jeder Rollenschiene 26 beider Schienengruppen c und d ermöglicht ein seitliches Trennen von Plattenformaten 22, 24 mit unterschiedlichsten Breitenabmessungen quer aufzuteilender Plattenstreifen 18, 20.As shown in FIG. 2, stacked workpiece plates can also be divided in this way. The pivotability of each roller rail 26 of both rail groups c and d enables a lateral separation of plate formats 22, 24 with different width dimensions of plate strips 18, 20 to be divided transversely.

Da im vorliegenden Falle beispielhaft eine Buntaufteilung von nur zwei Plattenstreifen 18, 20 erfolgen soll, war es deshalb ausreichend, nur die die Plattenformate 24 des Plattenstreifens 20 aufnehmende Schienengruppe d entsprechend schräg einzustellen, wozu es gleichfalls genügte, lediglich das an der Trennstelle (bei e) beider Schienengruppen c und d vorhandene Zylinderaggregat, bei 36' (Fig. 3) zu aktivieren. Dabei sei erwähnt, dass die Kolbenstangen 40 der Zylinderaggregate 36 an der jeweils benachbarten Rollenschiene 26 angelenkt sind, um auch die Schienenrückstellung in ihre zum Anschlaglineal 30 parallele Lage zu bewerkstelligen.Since in the present case, for example, only two plate strips 18, 20 are to be divided, it was therefore sufficient to adjust only the rail group d receiving the plate formats 24 of the plate strip 20 accordingly, for which it was also sufficient, only that at the separation point (at e ) Activate both cylinder groups c and d existing cylinder unit at 36 '(Fig. 3). It should be mentioned that the piston rods 40 of the cylinder units 36 are articulated on the respectively adjacent roller rail 26 in order to also bring the rail back into its position parallel to the stop ruler 30.

Sind mehr als zwei Plattenstreifen quer aufzuteilen, so ist es naheliegend, dass die Rollenschienen jeweils einen der Plattenstreifen aufzunehmen haben, die nicht am Anschlaglineal 30 anliegen, zueinander um unterschiedliche Winkel schräg einzustellen sind, um aus diesen Plattenstreifen hergestellte Plattenformate bei ihrer Vorschubbewegung in seitlicher Richtung voneinander wegzubewegen.If more than two plate strips are to be divided transversely, it is obvious that the roller rails each have to accommodate one of the plate strips that do not lie against the stop ruler 30, and must be set at different angles to one another in order to prevent plate formats produced from these plate strips from moving laterally move away from each other.
