Description

Die Erfindung betrifft eine Plattenbeschickungseinrichtung für Plattenaufteilsägen in einer Ausbildung gemäß dem Oberbegriff von Anspruch 1.The invention relates to a plate loading device for panel saws in a training according to the preamble of claim 1.

Bei bekannten Plattenbeschickungseinrichtungen dieser Art bildet der Walzenbeschleuniger eine einem Maschinentisch einer Plattenaufteilsäge vorgeschaltete, stationäre Baueinheit. Dieser werden durch einen Einschubwagen einzelne, von einem Plattenstapel abgeschobene Platten zugeführt, die, sobald sie zwischen untere, antreibbare Beschleunigungswalzen und obere, absenkbare Druckwalzen des Walzenbeschleunigers gelangen, von dessen Walzen erfaßt und mit wesentlich erhöhter Transportgeschwindigkeit auf den Maschinentisch der Plattenaufteilsäge gefördert werden. Es ist dadurch möglich, den Einschubwagen relativ kurze Transportstrecken ausführen zu lassen und bereits wieder eine Platte des Plattenstapels am Walzenbeschleuniger bereitzustellen, sobald die zuvor angelieferte Platte diesen verlassen hat. In known plate loading devices of this type the roller accelerator forms a machine table a stationary unit upstream of a panel sizing saw. These are separated by a slide-in car a plate stack is pushed off plates that once they are between lower, drivable accelerating rollers and upper, lowerable pressure rollers of the roller accelerator arrive, grasped by its rollers and with essential increased transport speed on the machine table of the Panel saw are promoted. It is possible make the slide-in cart relatively short transport distances to leave and again a plate of the plate stack to be provided on the roller accelerator as soon as the previously delivered plate has left it.

Auf dem Maschinentisch der Plattenaufteilsäge zur Ablage kommende Platten, beispielsweise Rohplatten sind danach einzeln oder als Plattenpaket kantenbündig auszurichten, was z. B. mit Hilfe eines zwischen Walzenbeschleuniger und Plattenaufteilsäge oberhalb des Maschinentisches horizontal verfahrbaren Übergabewagens bewerkstelligt werden kann, der anheb- und absenkbare Mitnahmeelemente aufweist. Diese sind mit Bezug auf die Walzen des Walzenbeschleunigers derart orientiert, daß sie hinter den auf dem Maschinentisch abgelegten Platten zwischen den Walzen absenkbar sind, um anschließend die auf dem Maschinentisch bereitgestellte Platte bzw. den Plattenstapel in Richtung auf die Plattenaufteilsäge zu verschieben und dabei an einen nach oben gesteuerten, sich parallel zur Schnittebene der Plattenaufteilsäge erstreckenden Anschlag anzulegen. Alternativ hierzu kann anstelle des Einschubwagens dieser Anschlag auch zum Plattenausrichten in Richtung auf eine hinter dem Walzenbeschleuniger vorgesehene Anschlagfläche gesteuert werden.On the machine table of the panel sizing saw for storage upcoming panels, for example raw panels, are then individual or to align flush as a plate package, which z. B. with the help of a between roller accelerator and panel saw horizontally movable above the machine table Transfer vehicle can be accomplished, the has lifting and lowering driving elements. These are with respect to the rollers of the roller accelerator oriented that they are behind those placed on the machine table Plates between the rollers can be lowered to subsequently the plate provided on the machine table or the plate stack in the direction of the panel sizing saw move and move to an upward controlled extending parallel to the cutting plane of the panel sizing saw Stop. Alternatively, you can instead of the slide-in trolley, this stop also for plate alignment towards one behind the roller accelerator intended stop surface can be controlled.

Walzenbeschleuniger und Einschubwagen bilden somit zwei voneinander unabhängig arbeitende und anzusteuernde Baueinheiten. Der Walzenbeschleuniger gestattet es hierbei nicht, den Übergabewagen dazu einzusetzen, im Zusammenwirken mit dem Einschubwagen Platten großen Gewichtes beispielsweise mittels saugenden Abhebeelementen vom Plattenstapel abzuheben und unter Umgehung des Walzenbeschleunigers auf dem Maschinentisch abzulegen (nicht druckschriftlich belegbarer, firmeninterner Stand der Technik der Anmelderin).Roller accelerators and slide-in carriages thus form two Modules that work independently and can be controlled. The roller accelerator does not allow to use the transfer vehicle in cooperation with the slide-in cart, for example, plates of great weight to be lifted off the plate stack by means of suction lifting elements and bypassing the roller accelerator on the Put down the machine table (not documented, state of the art of the applicant).

Der Erfindung liegt die Aufgabe zugrunde, eine Plattenbeschickungseinrichtung der im Oberbegriff des Anspruches 1 erläuterten Art anzugeben, deren Walzenbeschleuniger auch einen Einsatz des Übergabewagens im Zusammenwirken mit dem Einschubwagen für den Transport entsprechend schwerer Platten vom Plattenstapel auf den Maschinentisch ermöglicht.The invention has for its object a plate loading device which in the preamble of claim 1 Specify the type specified, the roller accelerator also use of the transfer vehicle in cooperation with the Slide-in carts for the transport of correspondingly heavy plates from the stack of plates to the machine table.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing Features of claim 1 solved.

Der Übergabewagen bildet somit zugleich einen Bestandteil des Walzenbeschleunigers, indem er dessen wenigstens eine obere Druckwalze trägt und derart positionierbar ist, daß sowohl ein Weitertransport von Platten durch wenigstens eine Beschleunigungswalze und eine Druckwalze möglich, als auch gegebenenfalls ein Ausrichten von auf den Maschinentisch abgelegten Einzelplatten bzw. eines Plattenpakets durch Anlegen an einen Winkelanschlag möglich ist.The transfer trolley thus also forms a component of the roller accelerator by changing at least one carries upper pressure roller and can be positioned such that both further transport of plates by at least one Accelerator roller and a pressure roller possible as well if necessary, aligning it on the machine table stored single plates or a plate package It is possible to put on an angle stop.

Eine Weiterbildung der Erfindung gemäß Anspruch 2 ermöglicht es, verfahrbare Träger und Übergabewagen unter Umgehung eines Plattentransportes durch Walzenbeschleunigung für den Transport schwerer oder mit empfindlicher Oberfläche versehener Platten vom Plattenstapel direkt auf den Maschinentisch einsetzen zu können. Ebenso lassen sich durch den verfahrbaren Träger allein dickere Einzelplatten oder Plattenpakete aus dünneren Einzelplatten vom Plattenstapel über die Beschleunigungswalzen hinweg auf den Maschinentisch schieben, wobei in diesem Falle der Übergabewagen in einer entsprechenden Positionierung oberhalb des Maschinentisches in Ruhestellung verbleiben kann.A development of the invention according to claim 2 enables es, movable carriers and transfer vehicles bypassing a plate transport by roller acceleration for the Transport heavy or with a sensitive surface Plates from the stack of plates directly on the machine table to be able to use. Likewise, the movable Carrier alone thicker single plates or plate packs from thinner individual plates from the plate stack over the Push the acceleration rollers away onto the machine table, in this case the transfer car in a corresponding Positioning above the machine table in Rest position can remain.

Weiterbildungen der Erfindung gemäß den Ansprüchen 3 oder 4 bieten hierbei den Vorteil, beim Transport schwerer Einzelplatten bzw. Plattenpakete keinen großen Höhenversatz zwischen Plattenabschiebeebene und Plattenauflageebene des Maschinentisches zu haben. Developments of the invention according to claims 3 or 4 offer the advantage of transporting heavy single panels or plate packs no large height offset between Plate push-off level and plate support level of the To have a machine table.

Bei der erfindungsgemäßen Konstruktion wird somit der obere Teil des üblichen Walzenbeschleunigers durch den Übergabewagen gebildet, der für den Transport von Einzelplatten bzw. Plattenpaketen mit absenkbaren Mitnehmern und/oder Saugelementen ausgestattet sein kann.In the construction according to the invention, the upper Part of the usual roller accelerator through the transfer car formed for the transport of single panels or Plate packs with lowerable carriers and / or suction elements can be equipped.

Für den Transport einzelner schwerer Platten bzw. von Plattenpaketen sind sämtliche Wagen zum Zwecke ihres Antriebes vorteilhaft mit wenigstens einem endlosen, über Umlenkrollen geführten, angetriebenen Schlepporgan kuppelbar. Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand von Unteransprüchen.For the transport of individual heavy plates or of plate packs are all cars for the purpose of their drive advantageous with at least one endless, over pulleys guided, driven towing element can be coupled. Further advantageous embodiments of the invention are the subject of subclaims.

Die Beschickungseinrichtung weist eine Aufnahme 10 für einen abzustapelnden, beispielsweise aus Rohplatten gebildeten Plattenstapel 12 auf. Diese kann beispielsweise durch einen Hubtisch gebildet sein. Vom Rohplattenstapel 12 sollen Einzelplatten 14 oder Plattenpakete auf einen Maschinentisch 16 einer nicht gezeigten Plattenaufteilsäge transportiert werden. Hierzu dient in bekannter Weise entweder ein horizontal verfahrbarer, nicht gezeigter Einschubwagen, der mit entsprechend anheb- und absenkbaren Plattenmitnahmeelementen ausgestattet ist oder, wie dargestellt, ein verfahrbarer, für den Plattentransport oberhalb des Rohplattenstapels 12 festzulegender Träger 18, der mit mehreren, den Plattenvorschub übernehmenden Mitnahmeeinheiten 20 bestückt ist, die unabhängig vom Träger 18 in der Weise arbeiten, daß durch diese bei stillgelegtem Träger 18 der Plattenabschub erfolgt.The loading device has a receptacle 10 for one to be stacked, for example formed from raw panels Plate stack 12 on. This can be done, for example, by a Be lift table formed. Individual plates are to be taken from the raw plate stack 12 14 or plate packs on a machine table 16 a panel saw, not shown, are transported. This is done in a known manner either horizontally movable, not shown slide-in cart, with the corresponding lifting and lowering plate driving elements is equipped or, as shown, a movable, for plate transport above the raw plate stack 12 to be determined carrier 18, the plate feeder with several take-over take-away units 20, which work independently of the carrier 18 in such a way that by this takes place when the carrier 18 is shut down.

Dem Träger 18 nachgeschaltet ist in bekannter Weise ein Walzenbeschleuniger 22, der die von den Plattenmitnahmeeinheiten 20 vom Rohplattenstapel 12 abgeschobenen Platten 14 erfaßt und mit erhöhter Transportgeschwindigkeit dem Maschinentisch 16 zuführt.The carrier 18 is connected in a known manner Roller accelerator 22, which of the plate drive units 20 plates 14 pushed off the raw plate stack 12 detected and with increased transport speed to the machine table 16 feeds.

Der Walzenbeschleuniger 22 weist vorzugsweise eine Vielzahl von in axialem Abstand zueinander gelagerten, antreibbaren, unteren Beschleunigungswalzen 24 sowie diesen in der gleichen Anzahl zugeordnete und sich für den Plattentransport mit ihrer Achse im wesentlichen in der die Antriebswelle 26 der Beschleunigungswalzen 24 aufnehmenden Vertikalebene a-a befindende obere, absenkbare Druckwalzen 28 auf.The roller accelerator 22 preferably has a plurality of axially spaced, drivable, lower acceleration rollers 24 as well as these in the same Number assigned and dedicated to plate transport with its axis essentially in the drive shaft 26 the vertical plane a-a receiving the acceleration rollers 24 located upper, lowerable pressure rollers 28.

Außerdem ist zwischen dem Einschubwagen oder dem verfahrbaren Träger 18 und der nicht mehr dargestellten Plattenaufteilsäge noch ein Übergabewagen 30 vorgesehen, der, analog zum Träger 18, auf einem diesem zugeordneten Führungsgestell 32 oberhalb des Rohplattenstapels 12 und des Maschinentisches 16 verfahrbar und feststellbar ist. Hierbei können beide Wagen 18, 30 über eine gemeinsame Antriebsvorrichtung 34 einzeln oder gemeinsam, inbesondere programmgesteuert, verfahrbar sein.There is also between the slide-in cart or the movable Carrier 18 and the panel saw, not shown another transfer carriage 30 is provided, which, analogously to the carrier 18, on a guide frame assigned to it 32 above the raw plate stack 12 and the machine table 16 is movable and lockable. Here you can both carriages 18, 30 via a common drive device 34 individually or together, in particular program-controlled, be movable.

Der Übergabewagen 30 bildet zugleich einen Teil des Walzenbeschleunigers 22, indem dessen oberen Druckwalzen 28 am Übergabewagen 30 jeweils mittels eines Zylinderaggregates 36 in geeigneter Weise anheb- und absenkbar geführt sind. The transfer carriage 30 also forms part of the roller accelerator 22 by its upper pressure rollers 28 on Transfer car 30 each by means of a cylinder unit 36 are raised and lowered in a suitable manner.

Außerdem trägt der Übergabewagen 30 noch anheb- und absenkbare Plattenmitnahmeelemente 38, die beispielsweise jeweils durch die Kolbenstange eines Zylinderaggregates 40 gebildet sein können. Diese sind zu den oberen Druckwalzen 28 seitlich derart versetzt angeordnet, daß sie in der Vertikalebene a-a zwischen den Beschleunigungswalzen 24 nach unten in ihre Plattenmitnahmestellung steuerbar sind. Außerdem sind die Zylinderaggregate 40, in Plattentransportrichtung gesehen, vorzugsweise hinter den oberen Druckwalzen 28 angeordnet.In addition, the transfer carriage 30 carries lifting and lowering Plate driving elements 38, each for example formed by the piston rod of a cylinder unit 40 could be. These are laterally to the upper pressure rollers 28 arranged so offset that they are in the vertical plane a-a down between the accelerating rollers 24 in their plate transport position are controllable. Also are the cylinder units 40, seen in the plate transport direction, preferably arranged behind the upper pressure rollers 28.

Zylinderaggregate 40 sowie obere Druckwalzen 28 sind an einer gemeinsamen Quertraverse 42 des Übergabewagens 30 gehalten.Cylinder units 40 and upper pressure rollers 28 are on a common crossbar 42 of the transfer carriage 30 held.

Die Beschleunigungswalzen 24 oder der Maschinentisch 16 sind vorzugsweise vertikal stufenlos verstellbar, was einfachheitshalber nicht gezeigt ist.The acceleration rollers 24 or the machine table 16 are preferably vertically continuously adjustable, which is for the sake of simplicity is not shown.

Die Antriebsvorrichtung 34 ist vorzugsweise durch zwei sich in Plattentransportrichtung erstreckende endlose, jeweils um Umlenkrollen 44 und 46 herum geführte, vorzugsweise aus Zahnriemen 48 bestehende Schlepporgane gebildet, die, auf gleicher Höhe, einander gegenüberliegend, vorgesehen sind. Alternativ könnten die Schlepporgane auch beispielsweise durch Ketten oder Seile gebildet sein.The drive device 34 is preferably by two itself endless in the plate transport direction, each around Deflection rollers 44 and 46 guided around, preferably from Timing belt 48 existing towing organs formed, the, on same height, opposite each other, are provided. Alternatively, the towing elements could also be used, for example be formed by chains or ropes.

Der Träger 18 oder, alternativ zu diesem, ein nicht dargestellter Einschubwagen, der Übergabewagen 30 und gegebenenfalls noch wenigstens ein weiterer, auf dem Führungsgestell 32 zwischen beiden Schlepporganen 48 geführter Wagen der Beschickungseinrichtung sind dabei mit dem gleichen Trum 50 der Zahnriemen 48 in geeigneter Weise und insbesondere programmgesteuert, beispielsweise durch Festklemmen eines Abschnittes ihres Trums 50 zwischen einer Klemmfläche 60 und einer durch einen linear beweglichen Betätigungskeil 62 verstellbaren Klemmbacke 64 der mitzuschleppenden Wagen 18, 30 kuppelbar. Betätigungskeil 62 und Klemmbacke 64 sind hierbei in einem gemeinsamen Führungsgehäuse 66 einer Kupplungsvorrichtung 68 geführt, das zugleich die Klemmfläche 60 aufweist.The carrier 18 or, alternatively to this, a not shown Insert car, the transfer car 30 and if necessary at least one more, on the guide frame 32 wagons run between the two towing organs The loading device is with the same strand 50 the toothed belt 48 in a suitable manner and in particular program-controlled, for example by clamping one Section of their run 50 between a clamping surface 60 and one adjustable by a linearly movable actuating wedge 62 Clamping jaw 64 of the wagons 18, 30 to be carried along detachable. Actuating wedge 62 and jaw 64 are here in a common guide housing 66 of a coupling device 68 guided, which also has the clamping surface 60.

Ist auf den Maschinentisch 16 eine vorbestimmte Anzahl von Platten, beispielsweise Hartfaserplatten bzw. ein Plattenpaket 52 transportiert bzw. auf ihn aufgeschichtet worden, und ist das abgelegte Plattenmaterial für den ersten Besäumschnitt kantenbündig auszurichten, wird der Übergabewagen 30 durch selbsttätiges Ankuppeln an die Riementrume 50 so weit in Richtung auf den in einer Abschiebestellung festgelegten Träger 18 verschoben, bis sich die Plattenmitnahmeelemente 38 hinter dem Plattenpaket 52 befinden. Danach werden die Zahnriemen 48 in die entgegengesetzte Richtung gesteuert, wobei dann das Plattenpaket 52 z. B. durch den Übergabewagen 30 in Richtung auf einen z. B. nach oben verschwenkbaren Plattenanschlag 54 verschoben wird. Anschließend wird letzterer in seine Freigabestellung gesteuert, so daß in der Folge das Plattenpaket 52 beispielsweise durch den Übergabewagen 30 im Zusammenwirken mit den Trumen 50 der Zahnriemen 48 zum Besäumen und Aufteilen schrittweise in Vorschubrichtung weiterverschoben werden kann. Es ist aber auch möglich, den Plattenanschlag 54 zum Plattenausrichten einzusetzen und diesen hierzu in Richtung auf eine hinter dem Walzenbeschleuniger 22 vorgesehene Anschlagfläche zu verschieben.Is on the machine table 16 a predetermined number of Boards, for example hardboard or a board package 52 transported or stacked on it, and is the stored board material for the first trimming cut to align the edges, the transfer carriage 30 by automatically coupling to belt space 50 so far towards the one set in a push-off position Carrier 18 moved until the plate driving elements 38 are located behind the plate pack 52. After that, the Toothed belt 48 controlled in the opposite direction, then the plate pack 52 z. B. by the transfer vehicle 30 towards a z. B. pivotable upwards Plate stop 54 is moved. Then the latter controlled in its release position, so that in the Follow the plate pack 52, for example, through the transfer cart 30 in cooperation with the strands 50 of the toothed belt 48 for trimming and dividing gradually in the feed direction can be postponed. But it is also possible insert the plate stop 54 for plate alignment and this in the direction of one behind the roller accelerator 22 intended to move stop surface.

Der Übergabewagen 30 kann, wie bei der gezeigten Plattenmitnahmeeinheit 20 des verfahrbaren Trägers 18 gezeigt, zusätzlich oder auch ausschließlich mit an eine Unterdruckquelle anschließbaren, z. B. mittels eines Zylinderaggregats 56 anheb- und absenkbar angeordneten Saugköpfen 58 ausgestattet sein. Dadurch besteht die Möglichkeit, den Übergabewagen 30 ebenfalls bei angehobenen oberen Druckwalzen 28 über den Plattenstapel 12 zu steuern und von diesem im Zusammenwirken mit den Saugköpfen 58 des Trägers 18 insbesondere schwere Einzelplatten 14 abzuheben. Darauf sind beide verfahrbaren Einheiten 18, 30 mit den Trumen 50 der beiden Zahnriemen 48 zu kuppeln und über den Maschinentisch 16 zur Plattenablage zu fahren.The transfer carriage 30 can, as in the plate carrier unit shown 20 of the movable carrier 18 shown, in addition or also exclusively with a vacuum source connectable, e.g. B. by means of a cylinder unit 56th Suction heads 58 arranged to be raised and lowered be. This makes it possible to transfer the transfer carriage 30 also with the upper pressure rollers 28 raised above the Control plate stack 12 and by this in cooperation especially heavy with the suction heads 58 of the carrier 18 Lift off individual plates 14. Both are movable on it Units 18, 30 with the runs 50 of the two toothed belts 48 to couple and over the machine table 16 to the plate storage to drive.

Aufgrund der erfindungsgemäßen Aufteilung des Walzenbeschleunigers 22 bildet dieser somit kein Transporthemmnis mehr für auf den Maschinentisch 16 aufzuschiebende Platten, indem dessen untere Beschleunigungswalzen 24 durch die Platte 14 überfahren werden können.Due to the division of the roller accelerator according to the invention 22 thus does not constitute a barrier to transportation more for 16 plates to be pushed onto the machine table, by its lower accelerating rollers 24 through the plate 14 can be run over.

Je nach Wahl des Steuerprogramms lassen sich dabei durch die Zahnriemen 48 anzutreibende Wagen gemeinsam in gleichen Richtungen oder einzeln, gegebenenfalls um unterschiedliche Strecken, in entgegengesetzte Richtungen steuern.Depending on the choice of control program, the Toothed belt 48 cars to be driven together in the same Directions or individually, possibly by different Stretch, steer in opposite directions.

Insbesondere für den Fall, daß die verfahrbaren Einheiten 18, 30 lediglich mit Saugköpfen 58 ausgestattet sein sollten, kann eine dritte verfahrbare Einheit beispielsweise einen üblichen, lediglich mit anheb- und absenkbaren Mitnehmern ausgestatteten Übergabewagen bilden, der den Plattenvorschub zur Plattenaufteilsäge übernimmt.Especially in the event that the movable units 18, 30 should only be equipped with suction heads 58, can, for example, a third movable unit a usual, only with lifting and lowering drivers equipped transfer car form the plate feed to the panel sizing saw.

Die Konstruktion des Führungsgestells 32 kann auch lediglich eine horizontale Führungsschiene aufweisen, an deren Unterseite die Plattenmitnahmeeinheiten 20 an einem verfahrbar angeordneten Querträger bzw. wenigstens einem Einschubwagen vorgesehen sein könnten. In diesem Falle würde ein Schlepporgan für den Antrieb aller mitzuschleppenden Einheiten genügen.The construction of the guide frame 32 can also only have a horizontal guide rail on the underside the plate driving units 20 can be moved on one arranged cross member or at least one slide-in cart could be provided. In this case, a towing device for driving all units to be carried are enough.
