Definitions
- the invention relates to a woodworking machine for tenoning and longitudinal profiling of window timbers with at least one tenoning and slot unit and at least one unit for longitudinal profiling, the tenoning and slot unit being assigned a roller table for guiding the window wood past the tenoning and slot spindles, a transfer device also being assigned is provided, with which the window timbers to be processed are transferred to a longitudinal profiling unit at right angles, and finally a revolving stage is provided for turning the window timber by 180 °.
- the rotating platform is arranged in the area of the tenoning and slotting device in the workflow in front of the longitudinal profiling device, the Window wood is first led with its one end face past the tenon and slot spindles and, after the tenons and slots have been attached, transferred to the rotating platform, rotated there by 180 ° and the tenon and slot unit for the second time, with tenons and slots attached to it other end face.
- the disadvantage of this known machine is that either the longitudinal profiling can be attached to the window wood provided on both sides with pegs and slots by means of the longitudinal profiling unit, unless a second longitudinal profiling unit is used to attach the longitudinal profiling to the opposite side, or that one Longitudinal profiling unit must be used, which enables longitudinal profiling on the opposite side by means of so-called left spindles.
- the first arrangement with the additional longitudinal profiling unit has the disadvantage that, in addition to the additional costs, the machine becomes more voluminous and complex, while in the second arrangement it is disadvantageous that the counter-stop provided there is interruptions for the passage of the tools onto the Must have spindles, which can adversely affect the promotion of short window timbers in particular.
- the invention is accordingly based on the object of designing a woodworking machine in such a way that a machine is produced which, in addition to compact construction, manages with as few units as possible.
- the revolving stage is arranged behind the longitudinal profiling unit in the workflow and that the window timbers provided with pins and slots on this side are transferred to the longitudinal profiling unit in this state, are longitudinally profiled there on one side, and are then conveyed to the revolving platform , can be turned through 180 ° to run through the machine for the second time.
- the other end face is accordingly provided with pins and slots and the side opposite the side already profiled is profiled lengthwise, since the window wood now passes through the machine in the turned state.
- the arrangement according to the invention makes it possible, in particular, to design the longitudinal profiling unit in such a way that the counterstop is continuously formed there without interruptions, so that the disadvantage of obstructing the conveyance of short window frames does not exist.
- the counterstop can be designed continuously because the longitudinal profiling of both sides of the window wood takes place from the same side, because the window wood is turned after the first pass through the longitudinal profile unit.
- the longitudinal profiling unit is not able to adjust the counterstop transversely in the usual way, but rather the longitudinal profiling spindles are delivered because this makes it possible to start longitudinally profiling the following wood while the end of the wood is still in the process preceding wood is located in the longitudinal profiling unit.
- the counter stop because it is no longer moved, can be made relatively long, so that a larger number of spindles can also be provided in succession in the longitudinal profiling unit.
- the infeed of the longitudinal profiling spindles is numerically controlled and if the dimension, that is to say the width, of the window wood is predetermined by the infeed of the longitudinal profiling spindles.
- a numerical control has the advantage that it works much more precisely than the previously known width controls by means of the counter-stop.
- Another advantage is that such an arrangement enables several longitudinal profiling spindles of the longitudinal profiling unit to be used simultaneously, each of the longitudinal profiling spindles producing part of the profile.
- regrinding of the tools does not lead to a new adjustment of the machine, since only a correction measure needs to be entered into the machine.
- Another advantage of the arrangement according to the invention is that, in contrast to the known arrangement, the removal of the first window wood provided with pins and slots can be made into the longitudinal profiling unit, while the subsequent window wood is provided with pins and slots. Such a streamlining of the workflow is not possible with the known arrangement, because there the subsequent window wood must be turned and moved back.
- a conveyor is expediently provided on the other side of the rotating platform, which transports the turned window wood back to the roller table.
- the transfer from this conveyor to the roller table can be done manually or automatically.
- the completed, i.e. Window wood provided with pegs and slots on both end faces and with longitudinal profiling on both sides is expediently conveyed beyond the longitudinal profiling unit.
- This promotion can also be carried out by an automatic switchover, which is expediently based on a program control.
- the outfeed can be based on various known types of conveyors.
- the axis of rotation of the rotating platform is expediently fixed between two conveyors arranged at a distance from one another, namely the conveyor from the rotating platform and the conveyor beyond the longitudinal profiling unit, the distance between the conveyors corresponding to the length of a horizontally arranged support which serves to hold the window frames and is turned through 180 ° in the horizontal plane.
- Intermediate conveyors extend from the two conveyors to the horizontal support, which on the one hand convey the window timbers to the support and on the other hand these from the support.
- the carrier of the rotating platform is lowered for the up and down conveyance.
- the woodworking machine according to the invention is particularly advantageously suitable for simultaneously processing two equally long and similar window timbers, so that a complete window can always be completed.
- a separating device of known type is expediently provided between the tenon and slot unit and the longitudinal profiling unit, which separates the two window timbers, which are provided with tenons and slots, so that these are successively, immediately adjacent to one another (joint to joint) can be promoted by the longitudinal profiling unit.
- This promotion and processing butt to butt can only take place if the window frames are the same, ie if the longitudinal profiling unit does not have to be switched between two window frames.
- the roller table can be moved back to its starting position and be reloaded for processing two next window timbers.
- the longitudinal control can expediently take place by means of a known movable stop in front of the tenon and slot unit.
- the tenoning and slotting unit is preceded by a cutting device in the form of a cross-cut saw, which cuts off a provisional dimension on the end face of the window timbers facing it during the first pass through the window timbers, while the adjustable stop specifies the final length during the second pass.
- the window wood can be brought to the system by hand or mechanically.
- the arrangement according to the invention also makes it possible, in particular, to carry out the successive or simultaneous processing of the end faces of the window timbers in a cycle or in a continuous pass by replacing the roller table with a circulating belt, a chain with supports or the like.
- Such a processing sequence which increases the throughput is excluded in the known arrangement because of the return of the window wood which is necessary there.
- the machining of the face of a window wood on both sides is surprisingly possible, as is the profiling on both sides, whereby the same units can be used for both operations.
- the additional tenon and slot units required in the known arrangements and the additional longitudinal profiling units are saved.
- the machine according to the invention can therefore be manufactured much more cost-effectively than the known machines.
- the figure shows a schematic representation of an embodiment of the woodworking machine according to the invention.
- the woodworking machine has a pin and slot unit 1, which is associated with a roller table 2 in a known manner, which is shown in the figure in its two end positions, with a transfer device 3 adjoining the pin and slot unit 1, which slider 4, with which the window timbers provided with pins and slots are fed to a separating device 5.
- a pneumatic unit of the separating device 5 is designated by 6.
- the window timbers are fed to a longitudinal profiling unit 8, in which a plurality of longitudinal profiling spindles 9 are provided, which can be set against the window timbers to be processed by means of a numerical control in the direction of the arrows 10.
- the counterstop against which the window timbers during the longitudinal profiling process are held, is designated 11. This counter-stop is immovably arranged in the longitudinal profiling unit.
- the longitudinal profiling unit 8 is followed by a turning device in the form of a rotating platform 12 which has a horizontally arranged support 13 which serves to hold the window frames and can be turned through 180 °.
- the carrier 13 is rotated in the direction of the arrow 14.
- the transfer of a lengthwise profiled window wood to the rotating stage 12 takes place with the interposition of a roller conveyor 15 via intermediate conveyor 16 and conveyor rails 17, the carrier 13 being in the position shown in the figure for receiving the window timbers, but being lowered in this.
- the window timbers are fed via conveyor rails 18 to a further roller conveyor 19, which serves as a discharge conveyor and from which the window timbers are conveyed again onto the roller table 2.
- the length control takes place here by means of a stop 21 movable in the direction of the double arrow 20, one of the pin and slot units 1 being connected upstream Cutting device in the form of a cutting saw that cuts window frames to the specified length.
- the window timbers therefore pass through the woodworking machine according to the invention twice in the direction of the arrows 7, and after the second pass beyond the longitudinal profiling unit 8 there is a discharge in the direction of the arrow 23 via a conveyor 24, further processing units, for example a grinding machine 25, being able to be connected to the woodworking machine .
- the mode of operation of the arrangement described is as follows:
- the window timbers to be processed, preferably two, are clamped on this side of the tenoning and slotting unit 1 on the roller table 2 and are guided past the cross-cut saw 22, which cuts off a preliminary measure on the end face of the window timbers facing it when the window timbers are first run through.
- the window timbers are then guided past the tenon drive and slot spindles 26 by means of the roller table 2 and thus provide their end faces with tenons and slots. Then they are by means of the
- the roller table 2 is conveyed into a transfer device, which essentially consists of the slide 4, which feeds the window timbers designated 27 to the separating device 5, in which they are separated from one another.
- the window timbers then pass through the longitudinal profiling unit 8 one after the other and are provided with longitudinal profiling on one side by means of the numerically adjustable longitudinal profiling spindles 9.
- the window frames are then again in pairs on the lowerable carrier 13 of the rotating stage 12, whereupon this is rotated by 180 ° in the direction of arrow 14, so that the turned window frames on the intermediate conveyor 18 and one Abier 19 can be promoted to the roller table 2 for the second time.
- the adjustable stop 21 now specifying the final length to which the window timbers are cut by means of the cross-cut saw 22. They are then provided with pins and slots on their other end face by means of the transfer device 3 fed to the separating device 5 and longitudinally profiled with the same units of the longitudinal profiling unit 8 on its second longitudinal side.
- the roller table 2 can be replaced by an encircling belt, a chain with supports or the like, so that the processing of the end faces of the window timbers can be carried out in time or in a continuous pass.
Description
Die Erfindung betrifft eine Holzbearbeitungsmaschine zum Zapfenschlagen und Längsprofilieren von Fensterhölzern mit wenigstens einer Zapfenschlag- und Schlitzeinheit und wenigstens einer Einheit zum Längsprofilieren, wobei der Zapfenschlag- und Schlitzeinheit ein Rolltisch zum Vorbeiführen des Fensterholzes an den Zapfenschlag- und Schlitzspindeln zugeordnet ist, wobei ferner eine Übergabeeinrichtung vorgesehen ist, mit welcher im rechten Winkel die zu bearbeitenden Fensterhölzer einer Längsprofiliereinheit übergeben werden und wobei schließlich eine Drehbühne zum Wenden des Fensterholzes um 180° vorgesehen ist.The invention relates to a woodworking machine for tenoning and longitudinal profiling of window timbers with at least one tenoning and slot unit and at least one unit for longitudinal profiling, the tenoning and slot unit being assigned a roller table for guiding the window wood past the tenoning and slot spindles, a transfer device also being assigned is provided, with which the window timbers to be processed are transferred to a longitudinal profiling unit at right angles, and finally a revolving stage is provided for turning the window timber by 180 °.
Bei einer bekannten Maschine dieser Art ist die Drehbühne im Bereich der Zapfenschlag- und Schlitzeinrichtung im Arbeitsablauf vor der Längsprofiliereinrichtung angeordnet, wobei das Fensterholz zunächst mit seiner einen Stirnseite an den Zapfenschlag-und Schlitzspindeln vorbeigeführt wird und nach Anbringung der Zapfen und Schlitze auf die Drehbühne übergeben wird, dort um 180° gedreht wird und zum zweiten Mal die Zapfenschlag- und Schlitzeinheit unter Anbringung von Zapfen und Schlitzen an seinem anderen Stirnende durchläuft.In a known machine of this type, the rotating platform is arranged in the area of the tenoning and slotting device in the workflow in front of the longitudinal profiling device, the Window wood is first led with its one end face past the tenon and slot spindles and, after the tenons and slots have been attached, transferred to the rotating platform, rotated there by 180 ° and the tenon and slot unit for the second time, with tenons and slots attached to it other end face.
Nachteilig bei dieser bekannten Maschine ist es, daß entweder nur an einer Seite des beidseitig mit Zapfen und Schlitzen versehenen Fensterholzes die Längsprofilierung mittels der Längsprofiliereinheit angebracht werden kann, sofern nicht eine zweite Längsprofiliereinheit zur Anbringung der Längsprofilierung auf der gegenüberliegenden Seite Verwendung findet, oder daß eine Längsprofiliereinheit verwendet werden muß, die mittels sogenannter linker Spindeln die Längsprofilierung auf der gegenüberliegenden Seite ermöglicht.The disadvantage of this known machine is that either the longitudinal profiling can be attached to the window wood provided on both sides with pegs and slots by means of the longitudinal profiling unit, unless a second longitudinal profiling unit is used to attach the longitudinal profiling to the opposite side, or that one Longitudinal profiling unit must be used, which enables longitudinal profiling on the opposite side by means of so-called left spindles.
Die erste Anordnung mit der zusätzlichen Längsprofiliereinheit hat aber den Nachteil, daß neben den zusätzlichen Kosten die Maschine voluminöser und aufwendiger wird, während es bei der zweiten Anordnung nachteilig ist, daß der dort vorgesehene Gegenanschlag Unterbrechungen für den Durchtritt der Werkzeuge auf den Spindeln aufweisen muß, was die Förderung von insbesondere kurzen Fensterhölzern nachteilig beeinflussen kann.However, the first arrangement with the additional longitudinal profiling unit has the disadvantage that, in addition to the additional costs, the machine becomes more voluminous and complex, while in the second arrangement it is disadvantageous that the counter-stop provided there is interruptions for the passage of the tools onto the Must have spindles, which can adversely affect the promotion of short window timbers in particular.
Der Erfindung liegt demgemäß die Aufgabe zugrunde, eine Holzbearbeitungsmaschine so auszubilden, daß eine Maschine erzeugt wird, die neben kompakter Bauweise mit möglichst wenig Aggregaten auskommt.The invention is accordingly based on the object of designing a woodworking machine in such a way that a machine is produced which, in addition to compact construction, manages with as few units as possible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Drehbühne im Arbeitsablauf hinter der Längsprofiliereinheit angeordnet ist und daß die an einer Seite mit Zapfen und Schlitzen versehenen Fensterhölzer in diesem Zustand der Längsprofiliereinheit übergeben werden, dort an einer Seite längsprofiliert werden, anschließend auf die Drehbühne gefördert werden, um 180° gewendet werden, um zum zweiten Mal durch die Maschine zu laufen. Beim zweiten Durchlauf wird demzufolge die andere Stirnseite mit Zapfen und Schlitzen versehen und die der bereits profilierten Seite gegenüberliegende Seite längsprofiliert, da das Fensterholz nunmehr im gewendeten Zustand die Maschine durchläuft.This object is achieved in that the revolving stage is arranged behind the longitudinal profiling unit in the workflow and that the window timbers provided with pins and slots on this side are transferred to the longitudinal profiling unit in this state, are longitudinally profiled there on one side, and are then conveyed to the revolving platform , can be turned through 180 ° to run through the machine for the second time. In the second pass, the other end face is accordingly provided with pins and slots and the side opposite the side already profiled is profiled lengthwise, since the window wood now passes through the machine in the turned state.
Mit dieser Anordnung wird erreicht, daß trotz der Anbringung von Zapfen und Schlitzen an beiden Stirnseiten des Fensterholzes und trotz der Längsprofilierung an beiden einander gegenüberliegenden Seiten jeweils nur eine Zapfenschlag- und Schlitzeinheit und nur eine Längsprofiliereinheit benötigt wird. Damit ist gegenüber den bekannten Maschinen eine sehr kompakte und kostengünstige Maschine geschaffen.With this arrangement it is achieved that despite the attachment of pegs and slots on both ends of the window wood and despite the longitudinal profile on both opposite one another Sides only one tenoning and slot unit and only one longitudinal profiling unit is required. This creates a very compact and inexpensive machine compared to the known machines.
Die erfindungsgemäße Anordnung ermöglicht es, insbesondere die Längsprofiliereinheit so auszubilden, daß dort der Gegenanschlag ohne Unterbrechungen durchgehend ausgebildet ist, so daß der Nachteil der Behinderung der Förderung kurzer Fensterhölzer nicht gegeben ist. Der Gegenanschlag kann nämlich deswegen durchgehend ausgebildet sein, weil die Längsprofilierung beider Seiten des Fensterholzes jeweils von derselben Seite aus erfolgt, weil das Fensterholz nach dem ersten Durchlauf durch die Längsprofiliereinheit gewendet wird.The arrangement according to the invention makes it possible, in particular, to design the longitudinal profiling unit in such a way that the counterstop is continuously formed there without interruptions, so that the disadvantage of obstructing the conveyance of short window frames does not exist. This is because the counterstop can be designed continuously because the longitudinal profiling of both sides of the window wood takes place from the same side, because the window wood is turned after the first pass through the longitudinal profile unit.
Besonders vorteilhaft ist es in diesem Zusammenhang, wenn bei der Längsprofiliereinheit nicht in üblicher Weise der Gegenanschlag quer verstellbar ist, sondern die Längsprofilierspindeln zugestellt werden, weil es hierdurch möglich wird, mit dem Längsprofilieren des nachfolgenden Holzes bereits zu beginnen, während sich noch das Ende des vorangehenden Holzes in der Längsprofiliereinheit befindet. Vorteilhaft ist es hierbei insbesondere, daß der Gegenanschlag, weil er nicht mehr bewegt wird, relativ lang ausgebildet werden kann, so daß auch eine größere Anzahl von Spindeln hintereinander in der Längsprofiliereinheit vorgesehen sein kann.In this context, it is particularly advantageous if the longitudinal profiling unit is not able to adjust the counterstop transversely in the usual way, but rather the longitudinal profiling spindles are delivered because this makes it possible to start longitudinally profiling the following wood while the end of the wood is still in the process preceding wood is located in the longitudinal profiling unit. It is particularly advantageous here that the counter stop, because it is no longer moved, can be made relatively long, so that a larger number of spindles can also be provided in succession in the longitudinal profiling unit.
Vorteilhaft ist es weiter, wenn die Zustellung der Längsprofilierspindeln numerisch gesteuert wird und wenn insoweit das Maß, also die Breite des Fensterholzes durch die Zustellung der Längsprofilierspindeln vorgegeben wird. Neben der Verwendung eines festen Gegenanschlages hat eine solche numerische Steuerung den Vorteil, daß sie sehr viel genauer arbeitet als die bisher bekannten Breiteneinsteuerungen mittels des Gegenanschlages.It is also advantageous if the infeed of the longitudinal profiling spindles is numerically controlled and if the dimension, that is to say the width, of the window wood is predetermined by the infeed of the longitudinal profiling spindles. In addition to the use of a fixed counter-stop, such a numerical control has the advantage that it works much more precisely than the previously known width controls by means of the counter-stop.
Unabhängig davon, lassen sich aber in der erfindungsgemäßen Maschine ohne weiteres Längsprofiliereinheiten der bisherigen Art, bei denen also der Gegenanschlag verstellbar ist, verwenden.Irrespective of this, however, longitudinal profiling units of the previous type, in which the counterstop is adjustable, can be used in the machine according to the invention.
Ein weiterer Vorteil besteht darin, daß es eine solche Anordnung ermöglicht, mehrere Längsprofilierspindeln der Längsprofiliereinheit gleichzeitig zum Einsatz zu bringen, wobei jede der Längsprofilierspindeln einen Teil des Profiles herstellt. Außerdem führt aufgrund der numerischen Steuerung der Zustellung ein Nachschliff der Werkzeuge nicht zu einer neuen Justierung der Maschine, da lediglich ein Korrekturmaß in die Maschine eingegeben zu werden braucht.Another advantage is that such an arrangement enables several longitudinal profiling spindles of the longitudinal profiling unit to be used simultaneously, each of the longitudinal profiling spindles producing part of the profile. In addition, due to the numerical control of the infeed, regrinding of the tools does not lead to a new adjustment of the machine, since only a correction measure needs to be entered into the machine.
Ein weiterer Vorteil der erfindungsgemaß Anordnung besteht darin, daß im Gegensatz zu der bekannten Anordnung die Abförderung des mit Zapfen und Schlitzen versehenen ersten Fensterholzes zur Längsprofiliereinheit erfolgen kann, während das nachfolgende Fensterholz mit Zapfen und Schlitzen versehen wird. Eine solche Straffung des Arbeitsablaufes ist bei der bekannten Anordnung nicht möglich, weil dort das nachfolgende Fensterholz gewendet und zurückgefahren werden muß.Another advantage of the arrangement according to the invention is that, in contrast to the known arrangement, the removal of the first window wood provided with pins and slots can be made into the longitudinal profiling unit, while the subsequent window wood is provided with pins and slots. Such a streamlining of the workflow is not possible with the known arrangement, because there the subsequent window wood must be turned and moved back.
Zweckmäßigerweise ist jenseits der Drehbühne ein Abförderer vorgesehen, welcher das gewendete Fensterholz wieder zum Rolltisch befördert. Die Übergabe von diesem Förderer auf den Rolltisch kann von Hand oder auch automatisch erfolgen.A conveyor is expediently provided on the other side of the rotating platform, which transports the turned window wood back to the roller table. The transfer from this conveyor to the roller table can be done manually or automatically.
Das fertiggestellte, d.h. an beiden Stirnseiten mit Zapfen und Schlitzen versehene und beidseitig längsprofilierte Fensterholz wird zweckmäßigerweise jenseits der Längsprofiliereinheit ausgefördert. Diese Ausförderung kann ebenfalls durch eine automatische Umschaltung erfolgen, die zweckmäßigerweise auf einer Programmsteuerung basiert. Hinsichtlich der Mechanik kann die Ausförderung auf verschiedenen bekannten Fördererarten basieren.The completed, i.e. Window wood provided with pegs and slots on both end faces and with longitudinal profiling on both sides is expediently conveyed beyond the longitudinal profiling unit. This promotion can also be carried out by an automatic switchover, which is expediently based on a program control. With regard to the mechanics, the outfeed can be based on various known types of conveyors.
Zweckmäßigerweise ist die Drehachse der Drehbühne ortsfest zwischen zwei im Abstand zueinander angeordneten Förderern, nämlich dem Abförderer von der Drehbühne und dem Ausförderer jenseits der Längsprofiliereinheit angeordnet, wobei der Abstand zwischen den Förderern der Länge eines horizontal angeordneten Trägers entspricht, welcher der Aufnahme der Fensterhölzer dient und um 180° in der Horizontalebene gewendet wird. Von den beiden Förderern erstrecken sich Zwischenförderer zu dem horizontalen Träger, die einerseits die Fensterhölzer auf den Träger und andererseits diese von dem Träger abfördern. Zur Auf- und Abförderung wird der Träger der Drehbühne abgesenkt.The axis of rotation of the rotating platform is expediently fixed between two conveyors arranged at a distance from one another, namely the conveyor from the rotating platform and the conveyor beyond the longitudinal profiling unit, the distance between the conveyors corresponding to the length of a horizontally arranged support which serves to hold the window frames and is turned through 180 ° in the horizontal plane. Intermediate conveyors extend from the two conveyors to the horizontal support, which on the one hand convey the window timbers to the support and on the other hand these from the support. The carrier of the rotating platform is lowered for the up and down conveyance.
Die erfindungsgemäße Holzbearbeitungsmaschine ist in besonders vorteilhafter Weise dafür geeignet, gleichzeitig zwei gleich lange und gleichartige Fensterhölzer zu bearbeiten, so daß immer ein komplettes Fenster fertiggestellt werden kann.The woodworking machine according to the invention is particularly advantageously suitable for simultaneously processing two equally long and similar window timbers, so that a complete window can always be completed.
In einem solchen Fall ist zweckmäßigerweise zwischen der Zapfenschlag- und Schlitzeinheit und der Längsprofiliereinheit eine Vereinzelungsvorrichtung bekannter Art vorgesehen, welche die gemeinsam mit Zapfen und Schlitzen versehenen beiden Fensterhölzer wieder trennt, so daß diese nacheinander, und zwar unmittelbar aneinander anschließend (Stoß an Stoß) durch die Längsprofiliereinheit gefördert werden können. Diese Förderung und Bearbeitung Stoß an Stoß kann allerdings nur dann erfolgen, wenn es sich um gleiche Fensterhölzer handelt, d.h. wenn die Längsprofiliereinheit nicht zwischen zwei Fensterhölzern umgestellt werden muß.In such a case, a separating device of known type is expediently provided between the tenon and slot unit and the longitudinal profiling unit, which separates the two window timbers, which are provided with tenons and slots, so that these are successively, immediately adjacent to one another (joint to joint) can be promoted by the longitudinal profiling unit. This promotion and processing butt to butt can only take place if the window frames are the same, ie if the longitudinal profiling unit does not have to be switched between two window frames.
Während des Vereinzelungsvorganges und während des anschließenden Längsprofiliervorganges kann der Rolltisch zur Bearbeitung zweier nächster Fensterhölzer in seine Ausgangsstellung zurückfahren und neu beladen werden.During the singling process and during the subsequent longitudinal profiling process, the roller table can be moved back to its starting position and be reloaded for processing two next window timbers.
Die Längseinsteuerung kann zweckmäßigerweise mittels eines an sich bekannten beweglichen Anschlages vor der Zapfenschlag-und Schlitzeinheit erfolgen. Zu diesem Zweck ist der Zapfenschlag- und Schlitzeinheit eine Ablängvorrichtung in Form einer Ablängsäge vorgeschaltet, die beim ersten Durchlauf der Fensterhölzer ein vorläufiges Maß an der ihr zugewandten Stirnseite der Fensterhölzer abschneidet, während beim zweiten Durchlauf der verstellbare Anschlag die endgültige Länge vorgibt. Gegen diesen Anschlag kann das Fensterholz von Hand oder mechanisch zur Anlage gebracht werden.The longitudinal control can expediently take place by means of a known movable stop in front of the tenon and slot unit. For this purpose, the tenoning and slotting unit is preceded by a cutting device in the form of a cross-cut saw, which cuts off a provisional dimension on the end face of the window timbers facing it during the first pass through the window timbers, while the adjustable stop specifies the final length during the second pass. Against this stop, the window wood can be brought to the system by hand or mechanically.
Die erfindungsgemäße Anordnung ermöglicht es insbesondere auch, die aufeinanderfolgende bzw. gleichzeitige Bearbeitung der Stirnseiten der Fensterhölzer im Takt oder im kontinuierlichen Durchlauf vorzunehmen, indem der Rolltisch durch ein umlaufendes Band, eine Kette mit Auflagern od. dgl. ersetzt wird. Eine solche, den Durchsatz erhöhende Bearbeitungsfolge ist bei der bekannten Anordnung wegen des dort notwendigen Rücklaufes des Fensterholzes ausgeschlossen.The arrangement according to the invention also makes it possible, in particular, to carry out the successive or simultaneous processing of the end faces of the window timbers in a cycle or in a continuous pass by replacing the roller table with a circulating belt, a chain with supports or the like. Such a processing sequence which increases the throughput is excluded in the known arrangement because of the return of the window wood which is necessary there.
Mit der erfindungsgemäßen Anordnung wird also in überraschender Weise die beidseitige Stirnseitenbearbeitung eines Fensterholzes ebenso möglich wie die beidseitige Längsprofilierung, wobei für beide Arbeitsgänge dieselben Aggregate Verwendung finden können. Damit werden trotz hervorragender Arbeitsergebnisse und einer genügenden Durchlaufgeschwindigkeit jeweils die bei den bekannten Anordnungen erforderlichen zusätzlichen Zapfenschlag- und Schlitzeinheiten und die zusätzlichen Längsprofiliereinheiten eingespart. Die erfindungsgemäße Maschine kann mithin wesentlich kostengünstiger als die bekannten Maschinen hergestellt werden.With the arrangement according to the invention, the machining of the face of a window wood on both sides is surprisingly possible, as is the profiling on both sides, whereby the same units can be used for both operations. Thus, despite the excellent work results and a sufficient throughput speed, the additional tenon and slot units required in the known arrangements and the additional longitudinal profiling units are saved. The machine according to the invention can therefore be manufactured much more cost-effectively than the known machines.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispieles in der Zeichnung näher erläutert.The invention is explained below with reference to an embodiment in the drawing.
Die Figur zeigt in schematischer Darstellung eine Ausführungsform der erfindungsgemäßen Holzbearbeitungsmaschine.The figure shows a schematic representation of an embodiment of the woodworking machine according to the invention.
Danach weist die erfindungsgemäße Holzbearbeitungsmaschine eine Zapfen- und Schlitzeinheit 1 auf, welcher in bekannter Weise ein Rolltisch 2 zugeordnet ist, der in der Figur in seinen beiden Endlagen dargestellt ist, wobei an die Zapfen-und Schlitzeinheit 1 eine Übergabevorrichtung 3 anschließt, die einen Schieber 4 aufweist, mit welchem die mit Zapfen und Schlitzen versehenen Fensterhölzer einer Vereinzelungseinrichtung 5 zugeführt werden. Ein Pneumatikaggregat der Vereinzelungsvorrichtung 5 ist mit 6 bezeichnet.Thereafter, the woodworking machine according to the invention has a pin and slot unit 1, which is associated with a roller table 2 in a known manner, which is shown in the figure in its two end positions, with a transfer device 3 adjoining the pin and slot unit 1, which slider 4, with which the window timbers provided with pins and slots are fed to a
Von der Vereinzelungsvorrichtung 5 werden die Fensterhölzer einer Längsprofiliereinheit 8 zugeführt, in welcher mehrere Längsprofilierspindeln 9 vorgesehen sind, die mittels einer numerischen Steuerung in Richtung der Pfeile 10 gegen die zu bearbeitenden Fensterhölzer zustellbar sind. Der Gegenanschlag, gegen den die Fensterhölzer während des Längsprofiliervorganges gehalten werden, ist mit 11 bezeichnet. Dieser Gegenanschlag ist in der Längsprofiliereinheit unbeweglich angeordnet.From the
An die Längsprofiliereinheit 8 schließt eine Wendevorrichtung in Form einer Drehbühne 12 an, die einen horizontal angeordneten Träger 13 aufweist, welcher der Aufnahme der Fensterhölzer dient und um 180° gewendet werden kann. Der Träger 13 wird hierzu in Richtung des Pfeiles 14 gedreht. Die Übergabe eines an einer Seite längsprofilierten Fensterholzes auf die Drehbühne 12 erfolgt unter Zwischenschaltung eines Rollenförderers 15 über Zwischenförderer 16 und Förderschienen 17, wobei zur Aufnahme der Fensterhölzer der Träger 13 sich in seiner in der Figur dargestellten Lage befindet, in dieser jedoch abgesenkt ist.The
Nach einer Wendung des Trägers 13 um 180° werden die Fensterhölzer über Förderschienen 18 einem weiteren Rollenförderer 19 zugeführt, der als Abförderer dient und von welchem aus die Fensterhölzer erneut auf den Rolltisch 2 gefördert werden. Die Längeneinsteuerung erfolgt hierbei mittels eines in Richtung des Doppelpfeiles 20 beweglichen Anschlages 21, wobei eine der Zapfen- und Schlitzeinheit 1 vorgeschaltete Ablängvorrichtung in Form einer Ablängsäge die Fensterhölzer auf die vorgegebene Länge schneidet.After the
Die Fensterhölzer durchlaufen also die erfindungsgemäße Holzbearbeitungsmaschine in Richtung der Pfeile 7 zweimal, wobei nach dem zweiten Durchlauf jenseits der Längsprofiliereinheit 8 eine Ausförderung in Richtung des Pfeiles 23 über einen Förderer 24 erfolgt, wobei sich an die Holzbearbeitungsmaschine weitere Bearbeitungseinheiten, beispielsweise eine Schleifmaschine 25 anschließen können.The window timbers therefore pass through the woodworking machine according to the invention twice in the direction of the arrows 7, and after the second pass beyond the
Die Wirkungsweise der beschriebenen Anordnung ist also folgende:
Die zu bearbeitenden Fensterhölzer, vorzugsweise zwei, werden diesseits der Zapfenschlag- und Schlitzeinheit 1 auf dem Rolltisch 2 festgespannt und mit diesem an der Ablängsäge 22 vorbeigeführt, die beim ersten Durchlauf der Fensterhölzer ein vorläufiges Maß an der ihr zugewandten Stirnseite der Fensterhölzer abschneidet. Anschließend werden die Fensterhölzer mittels des Rolltisches 2 an Zapfenschlag- und Schlitzspindeln 26 vorbeigeführt und so ihre Stirnseiten mit Zapfen und Schlitzen versehen. Daraufhin werden sie mittels des Rolltisches 2 in eine Übergabevorrichtung gefördert, die im wesentlichen aus dem Schieber 4 besteht, welcher die mit 27 bezeichneten Fensterhölzer der Vereinzelungsvorrichtung 5 zuführt, in welcher sie voneinander getrennt werden.The mode of operation of the arrangement described is as follows:
The window timbers to be processed, preferably two, are clamped on this side of the tenoning and slotting unit 1 on the roller table 2 and are guided past the
Die Fensterhölzer durchlaufen dann nacheinander die Längsprofiliereinheit 8 und werden dort mittels der numerisch zustellbaren Längsprofilierspindeln 9 an einer Seite mit einer Längsprofilierung versehen. Über den Rollenförderer 15 und die Zwischenförderer 16 und 17 werden die Fensterhölzer dann wieder paarweise auf den absenkbaren Träger 13 der Drehbühne 12 gefördert, worauf dieser um 180° in Richtung des Pfeiles 14 gedreht wird, so daß die gewendeten Fensterhölzer über den Zwischenförderer 18 und einen Abförderer 19 zum zweiten Mal auf den Rolltisch 2 gefördert werden können.The window timbers then pass through the
Nunmehr durchlaufen die Fensterhölzer zum zweiten Mal die Holzbearbeitungsmaschine, wobei der verstellbare Anschlag 21 nunmehr die endgültige Länge vorgibt, auf die die Fensterhölzer mittels der Ablängsäge 22 geschnitten werden. Anschließend werden sie an ihrer anderen Stirnseite mit Zapfen und Schlitzen versehen, mittels der Übergabevorrichtung 3 der Vereinzelungsvorrichtung 5 zugeführt und mit denselben Aggregaten der Längsprofiliereinheit 8 an ihrer zweiten Längsseite längsprofiliert.The window timbers now run through the woodworking machine for the second time, the adjustable stop 21 now specifying the final length to which the window timbers are cut by means of the cross-cut saw 22. They are then provided with pins and slots on their other end face by means of the transfer device 3 fed to the separating
Aufgrund einer Umschaltung werden sie sodann nicht dem Träger 13 der Drehbühne 12 zugeführt, sondern in Richtung des Pfeiles 23 ausgefördert.Due to a switchover, they are then not fed to the
Der Rolltisch 2 kann durch ein umlaufendes Band, eine Kette mir Auflagern od. dgl. ersetzt sein, so daß die Bearbeitung der Stirnseiten der Fensterhölzer im Takt oder im kontinuierlichen Durchlauf erfolgen kann.The roller table 2 can be replaced by an encircling belt, a chain with supports or the like, so that the processing of the end faces of the window timbers can be carried out in time or in a continuous pass.
