Abstract

A method for processing of workpieces, which are supplied to a processing station, in which the workpieces are processed on one side, are moved out of the processing station, and are turned and again supplied to the processing station for processing the second side. In particular, a workpiece or workpiece package is individually supplied to the processing station, is processed there and individually moved on following the processing of both sides. The first side of one workpiece, whose second side has not yet been processed, and the second side of another workpiece whose first side had already been processed in the previous processing operation, are processed in one processing operation in the processing station, so that during each processing operation a workpiece processed on both sides is created together with a workpiece processed only on one side.

Description

Verfahren zum Bearbeiten von WerkstückenProcess for machining workpieces
Technisches Gebiet der ErfindungTechnical field of the invention
Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method according to the preamble of patent claim 1.
Bearbeitungsverfahren innerhalb von Produktionseinrichtungen - z.B. der holzverarbeitenden Industrie auf dem Sektor "Keilzinkenanlagen" - sind hinlänglich bekannt. Diese haben jedoch allesamt den Nachteil, daß bei Verwendung von nur einer, mittels einer Vorschubeinrichtung beschickten Bearbeitungsmaschine - z.B. Keilzinkenmaschine - zur Erzeugung eines an beiden Enden fertig bearbeiteten Werkstückes oder Werkstückpaketes immer ein unproduktiver, zeitraubender Rücklauf der leeren Vorschubeinrichtung zum erneuten Beladen mit Werkstücken erforderlich ist.Machining processes within production facilities - e.g. the woodworking industry in the sector "finger jointing lines" - are well known. However, all of these have the disadvantage that when using only one processing machine fed by means of a feed device - e.g. Finger jointing machine - an unproductive, time-consuming return of the empty feed device for reloading with workpieces is always required to produce a workpiece or workpiece package that has been finished at both ends.
Stand der TechnikState of the art
Aus der gattungsbildenden Offenlegungsschrift 43 10 399 ist ein typisches Beispiel eines solchen Verfahrens bekannt. Beim Gegenstand dieser Offenlegungsschrift handelt es sich um eine Kombination von Vorschubbewegungen mit Drehbewegungen, wobei die Drehbewegung erforderlich ist, um die beiden beabstandeten oder gegenüberliegenden Seiten der jeweils zu verarbeitenden Werkstücke der Bearbeitungsstation zuzuführen. Hierzu dient ein Arbeitstisch, der an Enden-Bearbeitungswerkzeugen 3 und 4 mit aufgelegtem Werkstück vorbeigeführt wird und hierbei eine pendelnde Bewegung zwischen einer Anfangsposition und einer Endposition ausführt.A typical example of such a method is known from the generic laid-open publication 43 10 399. The subject of this laid-open document is a combination of feed movements with rotary movements, the rotary movement being necessary in order to feed the two spaced or opposite sides of the workpieces to be processed to the processing station. A work table is used for this purpose, which is guided past end machining tools 3 and 4 with the workpiece placed on them and in doing so executes an oscillating movement between a starting position and an end position.
Von besonderem Nachteil hierbei ist, daß der Rücklauf des Arbeitstisches auch hier leer, d.h. ohne aufgelegtes Werkstück, erfolgt, denn zur Drehung des Werkstückes ist außerhalb des Arbeitstisches 1 eine sehr aufwendige, in mehreren Arbeitsebenen (Fig. 2 der 43 10 399) verschiebbare Wendevorrichtung erforderlich, die auch Einrichtungen enthält, mit deren Hilfe der Rücktransport des einseitig bearbeiteten Werkstücks zur Anfangsposition des Arbeitstisches 1 erfolgt. Während also der Arbeitstisch im Leerlauf und somit ohne Arbeitsnutzen zurückfährt, wird parallel dazu die aufwendige Wendung des einseitig bearbeiteten Werkstücks durchgeführt.A particular disadvantage here is that the return of the work table is also empty here, ie without a workpiece placed on it, because for the rotation of the workpiece outside of the work table 1 is a very complex turning device that can be moved in several working levels (FIG. 2 of 43 10 399) required, which also contains devices with the aid of which the return transport of the workpiece machined on one side to the starting position of the work table 1 he follows. So while the work table moves back idle and thus without any benefit, the complex turning of the workpiece machined on one side is carried out in parallel.
Gegenstand der ErfindungSubject of the invention
Es ist Aufgabe der Erfindung, solche vorbekannten Bearbeitungsverfahren einfacher und rationeller auszubilden.It is an object of the invention to make such known processing methods simpler and more efficient.
Erfindungsgemäß wird diese Aufgabe mit den Merkmalen des kennzeichnenden Teils des Patentanspruchs 1 gelöst.According to the invention, this object is achieved with the features of the characterizing part of patent claim 1.
Der unproduktive Rücklauf der Vorschubeinrichtung (entsprechend dem Arbeitstisch 1) wird vermieden, indem nach einer bevorzugten Ausgestaltung der erfindungsgemäßen Lösung die Vorschubeinrichtung selbst zwischen aufeinanderfolgenden Arbeitszyklen gedreht wird und somit auch zum Rücktransport eines Werkstückes mit einseitig bearbeiteter Stirnfläche dient. Die Vorschubeinrichtung V erfüllt hier also eine Doppelfunktion insoweit, als sie Bearbeitungsvorschub, Drehung der Werkstücke und Rückfuhr der einseitig bearbeiteten Werkstücke wahrnimmt, Funktionen, die beim Gegenstand der Offenlegungsschrift 43 10 399 von separaten Einrichtungen übernommen werden müssen.The unproductive return of the feed device (corresponding to the work table 1) is avoided in that, according to a preferred embodiment of the solution according to the invention, the feed device itself is rotated between successive work cycles and thus also serves for the return transport of a workpiece with an end face machined on one side. The feed device V thus fulfills a double function insofar as it perceives the machining feed, rotation of the workpieces and return of the workpieces machined on one side, functions which must be taken over by separate devices in the case of the published patent application 43 10 399.
Beim erfindungsgemäßen Verfahren wird somit insbesondere der Rücklauf der Vorschubeinrichtung (entsprechend dem Arbeitstisch 1 bei der Offenlegungsschrift 43 10 399) arbeitstechnisch ebenfalls ausgenützt.In the method according to the invention, the return of the feed device (corresponding to the work table 1 in the published patent application 43 10 399) is thus also used in terms of work technology.
Es kommt beim Erfindungsgegenstand nach einer weiteren vorteilhaften Ausgestaltung auch nicht darauf an, ob einzelne Werkstücke oder ein aus gleichartigen Werkstücken gebildetes Werkstückpaket aufgegeben wird, sondern darauf, daß bei jedem Bearbeitungsvorgang (d.h. bei jedem Vorschub von zwei Werkstücken oder Werkstückpaketen an den Werkzeugen K) sich jeweils ein Werkstück oder Werkstückpaket auf der Vorschubeinrichtung V befindet, dessen erste Seite bearbei-tet wird, und ein Werkstück oder Werkstückpaket, dessen zweite Seite bearbeitet wird, vereinfacht ausgedrückt, vor oder nach jedem Bearbeitungsvorgang liegt auf der Vorschubeinrichtung ein Paar von Werkstücken oder Werkstückpaketen mit insgesamt einer ungeraden Anzahl von bearbeiteten Seiten. Beim dargestellten Ausführungsbeispiel (Fig. 5) der Erfindung handelt es sich um drei solcher bearbeiteter Seiten. Im Gegensatz hierzu befinden sich auf dem Arbeitstisch beim Gegenstand der Offenlegungsschrift 43 10 399 bei vergleichsweise paarweiser Bestückung immer ein Werkstückpaar mit gerader Anzahl von bearbeiteten Seiten, also insgesamt zwei oder vier bearbeitete Seiten.In the subject matter of the invention, according to a further advantageous embodiment, it is not important whether individual workpieces or a workpiece package formed from similar workpieces is given up, but rather that with each machining operation (ie with each feed of two workpieces or workpiece packages on the tools K) In each case, a workpiece or workpiece package is located on the feed device V, the first side of which is processed, and a workpiece or workpiece package, the second side of which is processed, in simplified terms, before or after each Processing process lies on the feed device a pair of workpieces or workpiece packages with a total of an odd number of machined pages. The illustrated embodiment (Fig. 5) of the invention is three such edited pages. In contrast to this, there is always a pair of workpieces with an even number of machined sides, ie a total of two or four machined sides, on the work table in the subject of laid-open specification 43 10 399 with comparatively paired assembly.
Bei der erfindungsgemäßen Ausführung des Verfahrens liegen immer mindestens zwei voneinander getrennte Werkstücke und/oder Werkstückpakete in der Vorschubeinrichtung bzw. deren Transporteinrichtungen. Dabei erfährt eines davon beim Durchlaufen der Werkzeuge der Bearbeitungsmaschine die erstmalige Bearbeitung, d.h. es ist danach erst auf einer Seite bearbeitet, ein weiteres Werkstück oder Werkstückpaket hingegen ist nach jedem Bearbeitungsvorgang bereits auf beiden Seiten fertig bearbeitet.In the embodiment of the method according to the invention, there are always at least two separate workpieces and / or workpiece packs in the feed device or its transport devices. One of them experiences the first-time processing when it passes through the tools of the processing machine, i.e. After that, it is only machined on one side, but another workpiece or workpiece package is already finished on both sides after each machining operation.
Der Vorteil gegenüber den bekannten Verfahren liegt somit darin, daß - abgesehen von dem ersten Bearbeitungsvorgang beim Ingangsetzen der Produktionseinrichtungen - in jedem weiteren Bearbeitungsvorgang während der gesamten Laufzeit dieser Einrichtungen mindestens ein an beiden Seiten fertig bearbeitetes Werkstück oder Werkstückpaket erzeugt wird. Ein unproduktiver Rücklauf leerer Vorschub- bzw. Transporteinrichtungen wird dabei vermieden, bei jedem Bearbeitungsvorgang entsteht somit ein Werkstück oder Werkstückpaket, das auf beiden Seiten fertig bearbeitet ist.The advantage over the known methods is thus that - apart from the first machining operation when the production facilities are started - at least one workpiece or workpiece package finished on both sides is produced in each further machining operation during the entire running time of these facilities. An unproductive return of empty feed or transport devices is avoided, with each machining process a workpiece or workpiece package is created that is finished on both sides.
Dies bedeutet eine erhebliche Verkürzung der Produktionszeiten der Werkstücke/Werkstückpakete und damit eine bedeutsame Produktivitätssteigerung der gesamten Produktionseinrichtung.This means a significant reduction in the production times of the workpieces / workpiece packages and thus a significant increase in productivity of the entire production facility.

Beschreibung eines bevorzugten Ausfuhrungsbeispiels des erfindungsgemäßen Verfahrens:Description of a preferred exemplary embodiment of the method according to the invention:
Das aus einer beliebigen Anzahl Werkstücke bestehende erste Werkstückpaket Wl - im folgenden "Werkstück" genannt - liegt auf einem Transportband Tl. Von dort wird es in Richtung H einem Transportband VI der in Position 1 in Wartestellung stehenden Vorschubeinrichtung V zugeführt.The first workpiece package Wl, consisting of any number of workpieces - hereinafter referred to as "workpiece" - lies on a conveyor belt T1. From there it is fed in the direction H to a conveyor belt VI of the feed device V which is in the waiting position 1.
Die Vorschubeinrichtung V bewegt sich nun in Richtung P und führt das zu bearbeitende erste Werkstück Wl den Bearbeitungswerkzeugen K zu (Fig. 1).The feed device V now moves in the direction P and leads the first workpiece W1 to be machined to the machining tools K (FIG. 1).
Nach Beendigen des Bearbeitungsvorgangs stoppt die Vorschubeinrichtung V in Position 2; die erste Seite W1A des ersten Werkstückes Wl ist jetzt bearbeitet. Die Vorschubeinrichtung V dreht sich nun um einen Winkel von 180° um ihre vertikale Achse Z (Fig. 2). Durch die aus der Drehung der Vorschubeinrichtung V resultierende Drehung des ersten Werkstückes Wl liegt die unbearbeitete zweite Werkstückseite WIB jetzt im Wirkungsbereich der Werkzeuge K, sie kann daher im nächsten Bearbeitungsvorgang bearbeitet werden. Die Vorschubeinrichtung V bewegt sich in Richtung R zurück und stoppt in Position 1 (Fig. 3).After completion of the machining process, the feed device V stops in position 2; the first side W1A of the first workpiece Wl is now processed. The feed device V now rotates through an angle of 180 ° about its vertical axis Z (FIG. 2). Due to the rotation of the first workpiece W1 resulting from the rotation of the feed device V, the unprocessed second workpiece side WIB is now in the effective range of the tools K and can therefore be machined in the next machining operation. The feed device V moves back in the direction R and stops in position 1 (FIG. 3).
Von der Transporteinrichtung Tl wird jetzt das zweite Werkstück W2 der Transporteinrichtung V2 zugeführt. Die Vorschubeinrichtung V bewegt sich nun wieder in Richtung P und führt die Werkstücke Wl und W2 gemeinsam den Bearbeitungswerkzeugen K zu (Fig. 4).The second workpiece W2 is now fed to the transport device V2 from the transport device T1. The feed device V now moves again in the direction P and leads the workpieces W1 and W2 together to the machining tools K (FIG. 4).
Nach Beendigung des Bearbeitungsvorgangs in der Bearbeitungsstation stoppt die Vorschubeinrichtung V in Position 2. Die beiden Seiten WlA und WIB des ersten Werkstückes Wl sowie die erste Seite W2A des zweiten Werkstückes W2 sind jetzt bearbeitet.After completion of the machining process in the machining station, the feed device V stops in position 2. The two sides WLA and WIB of the first workpiece W1 and the first side W2A of the second workpiece W2 are now processed.
Das erste Werkstück Wl ist nun fertig bearbeitet und wird in Richtung Y der Transporteinrichtung T2 zugeführt. Die Transporteinrichtung VI der Vorschubeinrichtung V wird dadurch leer (Fig. 5).The first workpiece W1 is now finished and is fed in the direction Y to the transport device T2. The transport device VI of the feed device V is thereby empty (Fig. 5).
Die Vorschubeinrichtung V dreht sich nun wieder um einen Winkel von 180° um ihre vertikale Achse Z.The feed device V now rotates again through an angle of 180 ° about its vertical axis Z.
Durch die daraus resultierende Drehung des zweiten Werkstückes W2 liegt dessen unbearbeitete zweite Werkstückseite W2B jetzt im Wirkungsbereich der Werkzeuge K und kann daher im nächsten Bearbeitungsvorgang bearbeitet werden.Due to the resulting rotation of the second workpiece W2, its unprocessed second workpiece side W2B is now in the effective range of the tools K and can therefore be processed in the next machining operation.
Die Vorschubeinrichtung V bewegt sich wieder in Richtung R zu Position 1 zurück, die oben beschriebenen und in den Fign. 3 und 4 dargestellten Vorgänge wiederholen sich nun weiterhin (Fig. 6). The feed device V moves back in the direction R to position 1, the ones described above and in FIGS. 3 and 4 processes are now repeated again (Fig. 6).
