Description

Die Erfindung betrifft eine Vorrichtung für die Zuführung von Montageteilen zu wenigstens einem Ober- oder Unterwerkzeug einer Montagemaschine zur Be- oder Verarbeitung der Montage-teile, wobei die Ober- und Unterwerkzeuge zwischen einer Arbeits- und einer Ruheposition relativ zueinander bewegbar sind und die Montageteile dem jeweiligen Werkzeug jeweils über einen Zuführkanal mittels eines Zuführstößels zugeführt werden.The invention relates to a device for feeding assembly parts to at least one upper or lower tool of an assembly machine for machining or processing the assembly parts, the upper and lower tools being movable relative to one another between a working position and a rest position, and the assembly parts each tool can be fed via a feed channel by means of a feed plunger.

Derartige Vorrichtungen für die Zuführung von Montageteilen sind an sich bekannt. Sie werden insbesondere in Maschinen zum Ansetzen von Nieten, Druckknöpfen oder dergleichen verwendet. Beispielsweise ist eine gattungsgemäße Vorrichtung für die Zuführung von Montageteilen in der DE-OS 42 25 264 beschrieben. Demgemäß ist ein federbelasteter Hebel mit einem Ausleger an einer an einem hubgesteuerten Oberwerkzeug angeordneten Führungsbahn angeordnet und wird durch die Abbewegung des Oberstempels entgegen der Federkraft in eine hintere Position gedrückt. Durch diese Bewegung wird ein Schlitten in eine zurückgezogene Position bewegt, an welchem Stößel angeordnet sind. Fährt der hubgesteuerte Oberstempel in seine obere Position zurück, wird der Hebel aufgrund der Federbelastung in eine vordere Position gezogen und bewegt dabei den Schlitten ebenfalls in eine vordere Position. Die Stößel prallen dann auf die in Zuführkanälen bereitgehaltenen Montageteile und führen diese dem Ober- und/oder Unterwerkzeug bzw. den daran angeordneten Haltewerkzeugen zu. Um ausreichend Zeit für das Einsetzen von Montageteilen in die Zuführkanäle zu haben, werden die Zuführstößel in eine weit hinter der Einsatzstelle befindliche Position zurückgeführt. Dadurch ergibt sich aufgrund der hohen Rückführgeschwindigkeit des Hebels eine erhebliche Aufprallgeschwindigkeit des Stößels auf die zuzuführenden Montageteile. Durch diesen Aufprall können die Teile in ungewünschter Weise beschädigt werden und es wird ein hoher Ausschuß produziert. Darüber hinaus müssen die Massen in entsprechend kurzer Zeit große Wege zurücklegen, so daß viel Energie für den Betrieb erforderlich ist. Will man beispielsweise durch eine entsprechende Hebelanordnung diese Wege verkürzen, verkürzt sich automatisch die Einsetzzeit. Weiterhin müssen viele Teile relativ zueinander positioniert, eingestellt und abgestimmt werden. Auch ist keine Steuerung oder einfache Variation der Einsetzzeit möglich. Aufgrund bestimmter Schalteranordnungen erfolgt eine Abschaltung, wenn der Vorschub der Stößel behindert ist. Aufgrund der hohen Beschleunigung bedarf es dazu jedoch bereits erheblicher Behinderungen. Nur leicht deformierte Teile oder dergleichen werden trotzdem zugeführt. Eine Einstellung dieser Reaktionskraft ist ebenfalls nicht möglich.Such devices for feeding assembly parts are known per se. They are used in particular in machines for riveting, snap fasteners or the like. For example, a generic device for feeding assembly parts is described in DE-OS 42 25 264. Accordingly, a spring-loaded lever with a cantilever is arranged on a guide track arranged on a stroke-controlled upper tool and is pressed into a rear position against the spring force by the movement of the upper punch. This movement moves a carriage into a retracted position, on which plungers are arranged. If the stroke-controlled upper punch moves back into its upper position, the lever is pulled into a front position due to the spring load and thereby also moves the slide into a front position. The plungers then hit the assembly parts held in the supply channels and guide them to the upper and / or lower tool or the holding tools arranged thereon. In order to have enough time for inserting assembly parts into the feed channels, the feed plungers are returned to a position far behind the point of use. Because of the high return speed of the lever, this results in a considerable impact speed of the ram on the assembly parts to be supplied. This impact can damage the parts in an undesired manner and a high scrap is produced. In addition, the masses have to travel long distances in a correspondingly short time, so that a lot of energy is required for operation is. If, for example, you want to shorten these distances with a suitable lever arrangement, the insertion time is automatically reduced. Furthermore, many parts have to be positioned, adjusted and adjusted relative to each other. Control or simple variation of the onset time is also not possible. Due to certain switch arrangements, a shutdown takes place if the feed of the plunger is obstructed. However, due to the high acceleration, considerable disabilities are required. Only slightly deformed parts or the like are still fed. Setting this reaction force is also not possible.

Aufgrund der mit hohen Geschwindigkeiten bewegten Massen sind die vorbekannten Vorrichtungen für die Zuführung von Montageteilen wartungsaufwendig und unterliegen einem hohen Verschleiß.Due to the masses moving at high speeds, the known devices for feeding assembly parts are maintenance-intensive and subject to high wear.

Davon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Vorrichtung für die Zuführung von Montageteilen der gattungsgemäßen Art dahingehend zu verbessern, daß der Aufbau vereinfacht, der Wartungsaufwand, die Verschleißanfälligkeit und der Einstellungs- bzw. Abstimmungsbedarf verringert werden und die Einsetzzeit mit einfachen Mitteln variierbar ist.Assuming the present invention is based on the object, the effect to improve a device for the supply of assembly parts of the generic type in that the structure is simplified, the maintenance, the susceptibility to wear and the adjustment or coordination requirements are reduced and the onset time varied by simple means is.

Zur technischen Lösung dieser Aufgabe wird vorgeschlagen, daß der Zuführstößel an einem Stößelwagen angeordnet ist, der in Stößellängsrichtung mittels einer Schubkurbel hin- und herbewegbar ist.For the technical solution to this problem, it is proposed that the feed tappet be arranged on a tappet carriage which can be moved back and forth in the longitudinal direction of the tappet by means of a push crank.

Durch die erfindungsgemäße Ausgestaltung wird die Zuführstößelbewegung in erster Linie unabhängig von der Bewegung der Werkzeuge, so daß die Möglichkeit zur Variation der Bewegungen verbessert wird. So kann der Zuführweg durch die Anordnung einer entsprechenden Schubkurbel verringert werden, so daß die Auftreffgeschwindigkeit des Zuführstößels auf die bereitgestellten Artikel kleiner ist. Weiterhin brauchen nicht so viele Massen mit hohen Geschwindigkeiten bewegt zu werden, so daß der Energieaufwand erheblich verringert wird. Darüber hinaus sind der Wartungs- und der Abstimmungsaufwand verringert.Due to the configuration according to the invention, the feed ram movement is primarily independent of the movement of the tools, so that the possibility of varying the movements is improved. Thus, the feed path can be reduced by arranging a corresponding push crank, so that the speed of impact of the feed plunger on the articles provided is lower. Furthermore, not so many masses need to be moved at high speeds, so that the energy consumption is considerably reduced. Maintenance and coordination efforts are also reduced.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung wird vorgeschlagen, daß der Stößelwagen mittels einer zentrischen Schubkurbel hin- und herbewegbar ist. Die zentrische Anordnung der Schubkurbel vermeidet die Verwendung anfälliger und abzustimmender Gestänge. In vorteilhafter Weise wird die zentrische Schubkurbel unterhalb des Stößelwagens zwischen den vorderen und hinteren Umkehrpunkten angeordnet. In besonders vorteilhafter Weise besteht die Verbindung zwischen der Schubkurbel und dem Stößelwagen aus einer an der Schubkurbel angeordneten Laufrolle, die in einer am Stößelwagen angeordneten Führungskurve abläuft, deren Breite der Umlaufkreisbahn der Laufrolle entspricht. Derartige Kurbeln werden Kreuzschubkurbeln genannt, die im Falle der vorliegenden Erfindung mit einer Kurve in Form eines Rastgetriebes kombiniert werden. Man spricht auch von Kreuzschubkurbeln mit Rast. Durch diese einfache Ausgestaltung ist die Anzahl der relativ zueinander bewegten Teile erheblich verringert. Darüber hinaus können eine Vielzahl drehender Teile eingesetzt werden, welche grundsätzlich eine bessere Einstell- und Abstimmöglichkeit bieten, gute Kraftübertragungen bereitstellen und wartungsunanfällig sind. In vorteilhafter Weise hat die Führungskurve einen Radius. Gemäß einem Vorschlag der Erfindung ist der Radius der Führungskurve derart, daß die Laufrolle ohne Schubkraftübertragung in einer der Umkehrpositionen über einen Winkel f abläuft. Durch diese Maßnahme ist es möglich, die Rastzeit des Stößelwagens in einer der beiden Umkehrpositionen festzulegen. In vorteilhafter Weise liegt der Mittelpunkt des Radius der Führungskurve zwischen der Führungskurve und den Stößeln, so daß sich eine Rastzeit in der hinteren Umkehrposition ergibt. Die Radiuslänge ist in vorteilhafter Weise einstellbar. Beispielsweise kann dies durch verstellbare Führungsbahnkulissen bewirkt werden.According to an advantageous embodiment of the invention, it is proposed that the ram can be moved back and forth by means of a central push crank. The central arrangement of the push crank avoids the use of the more susceptible and linkage to be adjusted. The central thrust crank is advantageously arranged below the push-rod carriage between the front and rear reversal points. In a particularly advantageous manner, the connection between the thrust crank and the tappet consists of a roller arranged on the thrust crank, which runs in a guide curve arranged on the tappet, the width of which corresponds to the orbit of the roller. Cranks of this type are called cross-slide cranks which, in the case of the present invention, are combined with a curve in the form of a detent gear. One speaks also of cross thrust cranks with rest. This simple design considerably reduces the number of parts that move relative to one another. In addition, a variety of rotating parts can be used, which generally offer better adjustment and tuning options, provide good power transmissions and are not prone to maintenance. The guide curve advantageously has a radius. According to a proposal of the invention, the radius of the guide curve is such that the roller runs over an angle f in one of the reversing positions without transmission of thrust. This measure makes it possible to determine the rest time of the ram in one of the two reversing positions. The center point of the radius of the guide curve advantageously lies between the guide curve and the tappets, so that there is a rest time in the rear reversing position. The radius length is advantageously adjustable. For example, this can be brought about by adjustable guideway backdrops.

In vorteilhafter Weise ist die Schubkurbel eine Scheibe, die gemäß einem Vorschlag der Erfindung in einer Getriebekette von einem Treibrad des Antriebs der Ansetzmaschine angetrieben wird.The thrust crank is advantageously a disk which, according to a proposal of the invention, is driven in a gear chain by a drive wheel of the drive of the attaching machine.

Gemäß einem Vorschlag der Erfindung ist der Stößelwagen ein Schlitten, der in vorteilhafter Weise zwei Stößel trägt. Somit können bei einer Vorwärtsbewegung sowohl dem Ober- als auch dem Unterwerkzeug Montageteile zugeführt werden. In vorteilhafter Weise sind die Stößel am Stößelwagen in Führungen eingesetzt. Dadurch wird eine leichte Einstellbarkeit und Auswechselbarkeit gewährleistet. Mit Vorteil wird vorgeschlagen, daß die Stößel in den Führungen mittels einer Rastverbindung angeordnet werden. Abgesehen von der leichten Auswechselbarkeit und Einstellbarkeit kann durch die Rastverbindung der Stößel in die Führung hereingeschoben werden, wenn er auf ein Hindernis trifft. Die Zerstörung von Maschinenteilen durch defekte Montageteile wird durch diese Rastung vermieden. In vorteilhafter Weise wird die Rastverbindung durch einen federbelasteten Rastnocken gebildet. Der Rastnocken rastet gemäß einem Vorschlag der Erfindung in einer Rastnut. Im Stößel wird eine gute Stößelführung bei gleichzeitiger Sicherheitsauslösung gewährleistet.According to a proposal of the invention, the tappet carriage is a carriage which advantageously carries two tappets. This allows assembly parts to be fed to both the upper and lower tool during a forward movement. The tappets are advantageously used in guides on the tappet carriage. This ensures easy adjustability and interchangeability. It is advantageously proposed that the tappets are arranged in the guides by means of a latching connection. In addition to being easy to replace and adjust, the plunger can be pushed into the guide if it encounters an obstacle. The destruction of machine parts due to defective assembly parts is avoided by this detent. The latching connection is advantageously formed by a spring-loaded latching cam. According to a proposal of the invention, the latching cam snaps into a latching groove. Good ram guidance is ensured in the ram with simultaneous safety release.

Gemäß einem vorteilhaften Vorschlag der Erfindung ist der Stößelwagen mit einem Schalteranschlag versehen, durch welchen in einer der Umkehrpositionen ein Schalter betätigt wird. Dieser Schalteranschlag betätigt beispielsweise eine Montageteilsperre, wobei gemäß einem Vorschlag der Erfindung mehrere Montageteilsperren anwählbar sind. Erreicht der Stößelwagen seine hintere Position, so wird der Schalter geschlossen und eine aus mehreren Möglichkeiten angewählte Montageteilsperre geöffnet. Das Montageteil wird freigegeben und im Zuführkanal bereitgestellt, bis der Stößelwagen in die vordere Position verschoben wird und die Stößel die Montageteile den Werkzeugen zuführen.According to an advantageous proposal of the invention, the ram is provided with a switch stop by which a switch is actuated in one of the reversing positions. This switch stop actuates, for example, a mounting part lock, wherein according to a proposal of the invention, a number of mounting part locks can be selected. When the ram reaches its rear position, the switch is closed and an assembly part lock selected from several options is opened. The assembly part is released and provided in the feed channel until the ram is moved to the front position and the rams feed the assembly parts to the tools.

Die einfache Steuerung des mit den Zuführstößeln versehenen Stößelwagens über eine Schubkurbel verringert den Energie-, Montage-, Einstell- und Wartungsaufwand einer Vorrichtung für die Zuführung von Montageteilen und verringert darüber hinaus die Geschwindigkeit, mit welcher der Stößel auf die zuzuführenden Montageteile auftrifft. Es ist ohne weiteres möglich, den Stößelwagen so zu steuern, daß die Stößel direkt hinter der Einlegestelle am Zuführkanal ihre hinterste Umkehrposition erreichen. Die Auftreffgeschwindigkeit ist dann nahezu null. Die Rastzeit, die für das Einlegen der Teile erforderlich ist, läßt sich in einfacher Weise durch die Ausgestaltung der mit dem Radius versehenen Führungskurve am Stößelwagen bewerkstelligen. Die Bewegungsgeschwindigkeiten können aufgrund der verkürzten Wege der zu bewegenden Teile verringert werden.The simple control of the pusher carriage provided with the feed plungers via a push crank reduces the energy, assembly, adjustment and maintenance expenditure of a device for feeding assembly parts and furthermore reduces the speed at which the plunger hits the assembly parts to be supplied. It is readily possible to control the ram so that the rams reach their rearmost reversal position directly behind the insertion point on the feed channel. The impact speed is then almost zero. The rest time, which is required for inserting the parts, can be accomplished in a simple manner by designing the guide curve provided with the radius on the ram. The movement speeds can be reduced due to the shorter distances of the parts to be moved.

Die in Figur 1 gezeigte schematische Darstellung einer Maschine zum Ansetzen von Nieten, Druckknöpfen und dergleichen zeigt die Einordnung einer Vorrichtung für die Zuführung von Montageteilen in die Gesamtanlage. Die Ansetzmaschine 1 umfaßt ein Oberwerkzeug 2 und ein Unterwerkzeug 3 sowie einen Antrieb 4. Durch den Antrieb 4 wird das Koppelglied 5 für das Oberwerkzeug angetrieben und über einen um eine Achse 7 drehenden Hebel 6 und einen Verbindungsarm 8 sowie einen Stößel der Oberstempel 9 auf- und abbewegt. Im Bereich des Oberstempels 9 ist ein Haltewerkzeug 10 angeordnet. Der Unterstempel 11, der durch eine Feder 12 in einer zurückgezogenen Position vorgespannt ist, wird über eine Getriebescheibe 13, mit der eine Kurvenscheibe 14 verbunden ist, von einem Hebel 16 ebenfalls hubgesteuert. Am Hebel 16 ist eine mit der Kurvenscheibe 14 zusammenwirkende Laufrolle 15 angeordnet, so daß der Hebel 16 um die Achse 17 Kippbewegungen durchführt, die über die Lauf-rolle 18 auf den Unterstempel 11 übertragen werden. Zuführstößel 19 sind an einem Stößelwagen 20 angeordnet, der mittels einer Schubkurbel 21 vorgeschoben und zurückgezogen wird. Zu diesem Zwecke ist an der Schubkurbel 21 eine Laufrolle 23 angeordnet, die in einer Führungskurve 22 des Stößelwagens abläuft.The schematic illustration of a machine for attaching rivets, push buttons and the like shown in FIG. 1 shows the arrangement of a device for feeding assembly parts into the overall system. The attaching machine 1 comprises an upper tool 2 and a lower tool 3 as well as a drive 4. The drive 4 drives the coupling member 5 for the upper tool and via a lever 6 rotating about an axis 7 and a connecting arm 8 and a plunger of the upper punches 9. and moved away. A holding tool 10 is arranged in the area of the upper punch 9. The lower punch 11, which is biased in a retracted position by a spring 12, is also stroke-controlled by a lever 16 via a gear disk 13 to which a cam disk 14 is connected. On the lever 16 a cooperating with the cam disc 14 roller 15 is arranged so that the lever 16 performs about the axis 17 tilting movements which are transmitted to the lower punch 11 via the roller 18. Feed rams 19 are arranged on a ram 20 which is pushed and retracted by means of a push crank 21. For this purpose, a roller 23 is arranged on the push crank 21, which runs in a guide curve 22 of the ram.

Wie Figuren 2 und 3 zeigen, hat die Führungskurve 22 einen Radius, so daß innerhalb eines Winkels f, der einstellbar ist, praktisch keine Kraftübertragungen zwischen der Laufrolle 23 und dem Stößelwagen 20 stattfinden. Dadurch wird die Rastzeit definiert, in welcher der Stößelwagen 20 ohne Vorschub in einer Umkehrpositionen verharrt. Diese Rastzeit kann zum Einsetzen von Montageteilen in nicht gezeigte Zuführkanäle genutzt werden. Der Stößelwagen 20 weist im gezeigten Ausführungsbeispiel zwei Stößelführungen 24 auf, in welchen Stößel 19 eingesetzt sind. Zu diesem Zwecke ragen in die Stößelführungen 24 Rastnocken 25. Im gezeigten Ausführungsbeispiel sind die Rastnocken 25 durch die Federn 26 federbelastet und durch einen Einstellbolzen 27 in ihrer Vorspannung bzw. Eindringtiefe einstellbar. An den Stößeln 19 sind entsprechend Rastnuten 28 ausgebildet. Im gezeigten Ausführungsbeispiel sind die Rastnocken durch am unteren Ende angeordnete Zylinderrollen, Paßstifte oder Kugeln 29 gebildet, die in die Rastnuten 28 der Zuführstößel 19 eingreifen. Bei Erreichen einer bestimmten Kraft an der Stößelvorderkante wird der Stößel 19 in die Stößelführung 24 hineingedrückt. Durch die Anordnung von Anschlagstiften 35 wird bewirkt, daß die Stößel 19 wieder in ihre Rastposition zurückgeschoben werden, wenn sich der Stößelwagen 20 in die hintere Umkehrposition bewegt.As FIGS. 2 and 3 show, the guide curve 22 has a radius, so that practically no force transmissions take place between the roller 23 and the tappet 20 within an angle f that is adjustable. This defines the rest time in which the ram 20 remains in a reversing position without being advanced. This rest period can be used for inserting assembly parts into feed channels, not shown. In the exemplary embodiment shown, the tappet carriage 20 has two tappet guides 24, in which tappets 19 are inserted. For this purpose, locking cams 25 protrude into the tappet guides 24. In the exemplary embodiment shown, the locking cams 25 are spring-loaded by the springs 26 and their pretensioning or penetration depth can be adjusted by means of an adjusting bolt 27. Corresponding locking grooves 28 are formed on the plungers 19. In the exemplary embodiment shown, the locking cams are formed by cylindrical rollers, dowel pins or balls 29 arranged at the lower end, which engage in the locking grooves 28 of the feed plungers 19. When a certain force is reached on the tappet leading edge, the tappet 19 is pressed into the tappet guide 24. By arranging stop pins 35 causes the plunger 19 to be pushed back into its latching position when the plunger carriage 20 moves into the rear reverse position.

Erreicht der Stößelwagen die hintere Umkehrposition, schlägt er gegen einen Schalter 31 an und schließt einen Schaltkreis. Die über einen Wählschalter 34 ausgewählte Artikelsperre 32 oder 33 öffnet dann und gibt ein Teil frei, welches im Zuführkanal bereitgestellt wird. Während dieser Zeit verharrt der Stößelwagen in seiner hinteren Position und die Laufrolle 23 bewegt sich ohne die Übertragung von Vorschubkräften durch die Führungskurve 22. Bei Erreichen des entsprechenden Endpunktes überträgt die von der zentralen Schubkurbel 21 getriebene Laufrolle 23 wieder Vorschubkräfte auf den Stößelwagen 20 und bewegt diesen in die vordere Umkehrposition. Die Stößel, die nur bis kurz hinter die Einlegeposition im Zuführkanal zurückgezogen sind, wenn der Stößelwagen 20 in seiner hinteren Umkehrposition ist, nehmen praktisch bei Beginn des Vorschubs die eingelegten Artikel mit. Beim Auftreffen auf die Artikel ist die Geschwindigkeit des Stößels nur sehr gering, da er keine Beschleunigungswege hatte.When the ram reaches the rear reverse position, it hits a switch 31 and closes a circuit. The article lock 32 or 33 selected via a selector switch 34 then opens and releases a part which is provided in the feed channel. During this time, the tappet remains in its rear position and the roller 23 moves without the transmission of feed forces through the guide curve 22. When the corresponding end point is reached, the roller 23 driven by the central thrust crank 21 again transfers feed forces to the tappet 20 and moves it to the front reverse position. The plungers, which are only retracted shortly behind the insertion position in the feed channel when the plunger carriage 20 is in its rear reversing position, take the inserted articles with them practically at the start of the feed. When hitting the articles, the speed of the ram is very low because it had no acceleration paths.

Der Stößelwagen 20 ist in vorteilhafter Weise durch eine mit einer Führungskurve versehene Platte gebildet, auf welcher durch das Aufbringen von im wesentlichen winkligen Teilen Stößelführungen gebildet sind. Für beide Stößelführungen können im wesentlichen die gleichen Teile verwendet werden.The tappet carriage 20 is advantageously formed by a plate provided with a guide curve, on which tappet guides are formed by the application of essentially angled parts. Essentially the same parts can be used for both ram guides.
