- the inclination of the axis of rotation x-x and thus the catch arms 19 relative to the bending plane 1 can be adjusted by pivoting the swivel head 16 about its swivel axis 17.
- the inclination of the axis of rotation x-x is expediently chosen so large that the stirrups to be caught slide securely into the rest position on the catch arm and that the catch arm rotated into the emptying position assumes an almost horizontal position, thereby facilitating the removal of the tied stirrup package.
- the invention is not limited to the exemplary embodiment explained above, but that it can be modified in various ways within the scope of the general inventive concept.
- the mechanism for pivoting the catch arms could also be formed by a single, double-acting switching element connected to the catch arm.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Entfernen von Drahtbügeln von einer Bügelbiegemaschine, mit einem an die geneigte Biegeebene der Biegemaschine heran bewegbaren drehbaren Fangarmstern, dessen Fangarme nacheinander zur Aufnahme je einer vorbestimmten Anzahl von Drahtbügeln in die Fangposition drehbar sind, in welcher sie gegen eine im Bereich der Biege- und Abtrennwerkzeuge gelegene Fangstelle in der Biegeebene gerichtet sind.The invention relates to a device for removing wire brackets from a bow bending machine, with a rotatable catch arm star that can be moved towards the inclined bending plane of the bending machine, the catch arms of which can be rotated one after the other for receiving a predetermined number of wire brackets into the catch position, in which they counter against one in the area of the bending and severing tools located catch point in the bending plane.
Bei einer aus der AT-PS 378.489 bekannten Vorrichtung dieser Art ist der Fangarmstern an einem auf dem Boden verfahrbaren Wagen montiert. Diese Ausbildung hat den Nachteil, daß die Positionierung des Fangarmsternes relativ zu den Biegewerkzeugen von Hand erfolgen muß und dementsprechend ungenau ist und daß außerdem die Gefahr einer Verlagerung des Fangarmsternes aus der vorbestimmten Stellung infolge der beim Abtrennen der fertigen Bügel auftretenden, ein Wegspringen der Bügel verursachenden Kräfte besteht.In a device of this type known from AT-PS 378,489, the tentacle arm is mounted on a carriage which can be moved on the floor. This design has the disadvantage that the positioning of the tent arm star relative to the bending tools has to be done by hand and is accordingly inaccurate and that there is also the risk of the tent arm star being displaced from the predetermined position as a result of the brackets causing the brackets to jump off when the finished bracket is separated Powers.
Die Erfindung zielt darauf ab, eine Vorrichtung der einleitend angegebenen Art zu schaffen, welche die geschilderten Nachteile vermeidet und eine exakte Einstellung der Fangarme auf die Fangstelle sowie eine sichere und störungsfreie Aufnahme der abgeworfenen Drahtbügel gewährleistet. Die erfindungsgemäße Vorrichtung zeichnet sich dadurch aus, daß der Fangarmstern in einem Schwenkkopf am freien Ende eines über die Biegeebene auskragenden teleskopartig ausziehbaren Tragarmes drehbar ist, der entlang der Biegeebene translatorisch bewegbar geführt ist, wobei die Neigung des Fangarmsternes relativ zur Biegeebene durch Verschwenken des Schwenkkopfes einstellbar ist.The invention aims to provide a device of the type mentioned in the introduction, which avoids the disadvantages described and ensures an exact setting of the tentacles on the catching point and a safe and trouble-free reception of the dropped wire bracket. The device according to the invention is characterized in that the star arm star is rotatable in a swivel head at the free end of a telescopically extendable support arm which projects over the bending plane and is guided in a translationally movable manner along the bending plane, the inclination of the star arm star being adjustable relative to the bending plane by pivoting the swivel head is.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist jeder Fangarm am Drehteil des Fangarmsternes um eine quer zur Fangarmlängsrichtung verlaufende Achse schwenkbar montiert und mittels einer am Drehteil des Fangarmsternes montierten, gleichzeitig mit dem Abtrennvorgang angesteuerten Betätigungseinrichtung gegen die Biegeebene hin und von dieser weg schwenkbar.According to a preferred embodiment of the invention, each catch arm is mounted on the rotating part of the catch arm star so as to be pivotable about an axis running transversely to the longitudinal direction of the catch arm and is actuated at the same time as the separation process by means of a mounted on the rotating part of the catch arm star Actuating device can be pivoted towards and away from the bending plane.
Die Erfindung ermöglicht eine exakte und unverrückbare Einstellung des Fangarmsternes bzw. jedes Fangarmes relativ zur Biegestelle sowie eine einwandfreie Aufnahme der unter der Wirkung der beim Abtrennvorgang auftretenden Kräfte von der Biegeebene weg geschleuderten Drahtbügel. Insbesondere kann sich jeder Fangarm in der Fangposition mit seinem freien Ende im Zeitpunkt des Abtrennens des Drahtbügels vom Drahtvorrat in den Bügel hinein bewegen, so daß ein Ausweichen oder Abgleiten des Bügels unmöglich ist.The invention enables an exact and immovable setting of the tentacle star or each tentacle relative to the bending point as well as a perfect absorption of the wire bow thrown away from the bending plane under the effect of the forces occurring during the severing process. In particular, each catch arm can move with its free end into the catch position in the catch position at the time the wire bracket is separated from the wire supply, so that it is impossible for the bracket to evade or slide off.
Nach einem weiteren Merkmal der Erfindung ist jedem Fangarm ein am Drehteil des Fangarmsternes starr montierter Schutzbügel zugeordnet, der sich oberhalb des Fangarmes zu diesem geneigt erstreckt.According to a further feature of the invention, each guard arm is assigned a protective bracket which is rigidly mounted on the rotating part of the guard arm star and extends above the guard arm at an inclination to the latter.
Im Rahmen der Erfindung ist ferner für die Einstellung des Gleitkopfes, des Teleskoparmes und des Schwenkkopfes auf die Fangstelle sowie für die Steuerung der Betätigungseinrichtung der Fangarme eine elektronische Programmsteuereinrichtung vorgesehen.In the context of the invention, an electronic program control device is also provided for the adjustment of the sliding head, the telescopic arm and the swivel head to the catching point and for the control of the actuating device of the catching arms.
Weitere Merkmale der Erfindung werden nachfolgend an einem Ausführungsbeispiel unter Bezugnahme auf die Zeichnungen näher erläutert.
- Fig. 1 zeigt schematisch eine Vorrichtung gemäß der Erfindung in der Draufsicht und
- Fig. 2 in der Seitenansicht.
- Fig. 1 shows schematically a device according to the invention in plan view and
- Fig. 2 in side view.
Die Vorrichtung ist an einer zum Herstellen von Drahtbügeln bestimmten Biegemaschine montiert, von der die zur Vertikalen geneigte Biegeebene 1, die in dieser angeordneten Biegewerkzeuge 2 und eine zum Abtrennen der gebogenen Bügel von einem intermittierend vorgeschobenen Draht dienende Schere 3 schematisch dargestellt sind. Die Vorrichtung weist einen Gleitkopf 4 auf, der an einer entlang der Oberseite der Biegeebene 1 verlaufenden Schiene 5 geführt und mit einer von einem elektrischen Antriebsmotor 6 angetriebenen Antriebsspindel 7 über eine mit dem Gleitkopf fest verbundene Spindelmutter 8 in Eingriff steht. Der Gleitkopf 4 ist mit einem Arm 9 verbunden, der über die geneigte Biegeebene 1 der Bügelbiegemaschine auskragt und an seinem freien Ende einen im wesentlichen parallel zur Biegeebene 1 verlaufenden Teleskoparm 10 trägt. Dieser Teleskoparm 10 besteht aus einer Führungshülse 11 und einem in dieser verschiebbaren Armteil 12, der mittels einer von einem elektrischen Antriebsmotor 13 antreibbaren Antriebsspindel 14 über eine mit dem Armteil fest verbundene Spindelmutter 15 relativ zur Hülse 11 bewegbar ist.The device is mounted on a bending machine intended for the production of wire brackets, of which the
Am freien Ende des Teleskoparms 10 ist ein Schwenkkopf 16 um eine zur Biegeebene parallele Achse 17 schwenkbar befestigt. Im Schwenkkopf 16 ist ein Fangarmstern 18 drehbar gelagert, der beim dargestellten Ausführungsbeispiel mit drei Bügelfangarmen 19 ausgestattet ist, die gleichen gegenseitigen Winkelabstand haben. Der Fangarmstern 18 ist um eine zur Schwenkkopfebene senkrechte Achse x-x mittels einer elektrischen Antriebseinrichtung 20 drehbar. Jeder Fangarm 19 ist am Drehteil 18' des Fangarmsternes bei 21 schwenkbar gelagert und in der Fangposition mittels eines vor der Schwenkachse angreifenden Betätigungselementes 22, z.B. eines hydraulischen Schaltkolbens, entgegen der Wirkung einer mit dem hinteren Armende verbundenen Druckfeder 23 gegen die Biegeebene 1 hin schwenkbar. Das freie Ende 19' des Fangarmes 19 ist gegen die Biegeebene 1 hin abgebogen, damit auch mehradrig gebogene Bügel sicher gefangen werden können. Vom Schwenkkopf 16 erstreckt sich oberhalb jedes Fangarmes 19 ein Schutzbügel 24 bis über das Ende des Fangarmes hinaus.At the free end of the
Wie insbesondere Fig. 2 zeigt, sind der Schwenkkopf 16 und der Fangarmstern 18 relativ zur Biegeebene 1 derart geneigt, daß die Fangarme 19 mit der Biegeebene 1 einen spitzen Winkel einschließen.As shown in FIG. 2 in particular, the
Im Betrieb werden mit Hilfe einer nicht gezeigten elektronischen Programmsteuereinrichtung die Längen der Schenkel und die Biegewinkel zwischen den Schenkeln der herzustellenden Bügel sowie die erforderlichen Stückzahlen bzw. die von jedem Fangarm aufzunehmende Stückzahl voreingestellt, wobei als Datenträger z.B. Lochstreifen oder Magnetbänder dienen. Die Steuereinrichtung bewirkt zunächst ein Verfahren des Gleitkopfes 4 auf die durch die Bügelform bestimmte Position der Fangstelle sowie ein Ausrichten des Schwenkkopfes 16 mit Hilfe des Teleskoparmes 10 auf die Fangstelle und eine entsprechende Neigung des Fangarmsternes 18 relativ zur Biegeebene 1 durch Schwenken des Schwenkkopfes 16 um die Achse 17 mit Hilfe einer nicht gezeigten Schwenkeinrichtung, z.B. einem Spindelantrieb. Die Neigung wird vorzugsweise so gewählt, daß während des Biegevorganges zwischen dem freien Ende 19' des Fangarmes 19 und der Biegeebene 1 ein genügend großer Abstand verbleibt, damit die Bewegung des Bügels während des Biegevorganges nicht behindert wird. Sobald ein leerer Fangarm 19 auf die den Biegewerkzeugen 2 in Drahtvorschubrichtung nachgeschaltete Fangstelle ausgerichtet ist, bewirkt die Steuereinrichtung, daß der Fangarm 19 jeweils durch einen gleichzeitig mit dem Abtrennen eines fertig gebogenen Bügels B mittels der Schere 3 abgegebenen Schaltimpulses mittels des Betätigungselementes 22 gegen die Biegeebene geschwenkt wird, so daß der unter der Abtrennkraft wegspringende Bügel vom Fangarm gefangen wird und zufolge der Schräglage des Fangarmes auf diesem nach hinten gleitet. Insbesondere können auf diese Weise auch mehradrig gebogene Bügel sicher gefangen werden. Das gebogene freie Fangarmende 19' erleichtert die Aufnahme des Bügels. Nach der Aufnahme des Bügels schwenkt der Fangarm 19 um seine Schwenkachse 21 unter der Wirkung der Druckfeder 23 in seine Ausgangsstellung zurück. Der relativ zum Fangarm 19 leicht geneigt verlaufende Schutzbügel 24 beruhigt die durch die Abtrennkraft verursachten Auf- und Abbewegungen der Bügel auf dem Fangarm. Für die nicht in Fangposition befindlichen Fangarme 19 dient der Schutzbügel 24 zugleich als Personenschutz. Nach der Aufnahme der voreingestellten Bügelanzahl wird der Fangarmstern 18 mit Hilfe der Steuereinrichtung, welche die Drehantriebseinrichtung 20 betätigt, um eine Armteilung gedreht. Die Bügel B können dann mittels einer geeigneten, nicht dargestellten Abbindeeinrichtung abgebunden und vom vollen Fangarm abgenommen werden.In operation, the lengths of the legs and the bending angles between the legs of the stirrups to be produced, as well as the required number of pieces or the number of pieces to be taken up by each catch arm, are preset using an electronic program control device (not shown), where, for example, perforated strips or magnetic tapes serve as data carriers. The control device first effects a movement of the sliding head 4 to the position of the catch point determined by the bow shape, and an alignment of the
Die Neigung der Drehachse x-x und damit der Fangarme 19 relativ zur Biegeebene 1 läßt sich durch Schwenken des Schwenkkopfes 16 um seine Schwenkachse 17 einstellen. Die Neigung der Drehachse x-x wird zweckmäßig so groß gewählt, daß die zu fangenden Bügel auf dem Fangarm sicher in die Ruhelage gleiten und daß der jeweils in die Entleerstellung gedrehte Fangarm eine nahezu horizontale Lage einnimmt, wodurch die Entnahme des abgebundenen Bügelpaketes erleichtert wird.The inclination of the axis of rotation x-x and thus the
Es versteht sich, daß die Erfindung nicht auf das vorstehend erläuterte Ausführungsbeispiel beschränkt ist, dieses vielmehr im Rahmen des allgemeinen Erfindungsgedankens verschiedentlich abgewandelt werden kann. So können insbesondere anstelle der Spindelantriebe für den Gleitkopf und für den Teleskoparm auch andere Antriebseinrichtungen gewählt werden. Ferner könnte der Mechanismus für die Schwenkbetätigung der Fangarme auch durch ein einziges mit dem Fangarm verbundenes doppeltwirkendes Schaltorgan gebildet sein. Der beim gezeigten Beispiel mit drei Fangarmen ausgestattete Fangarmstern kann auch mehr als drei Arme haben, die auch unterschiedlichen Winkelabstand haben können, weist aber zumindest zwei Fangarme auf. Mit Ausnahme der Schwenkbewegung der Fangarme gegen die Biegeebene hin könnten einige der Steuerbewegungen der erfindungsgemäßen Vorrichtung auch von Hand ausgeführt werden.It goes without saying that the invention is not limited to the exemplary embodiment explained above, but that it can be modified in various ways within the scope of the general inventive concept. In particular, instead of the spindle drives for the sliding head and for the telescopic arm, other drive devices can also be selected. Furthermore, the mechanism for pivoting the catch arms could also be formed by a single, double-acting switching element connected to the catch arm. The tentacle star equipped with three tentacles in the example shown can also have more than three arms, which can also have different angular spacing, but has at least two tentacles. With the exception of the pivoting movement of the catch arms towards the bending plane, some of the control movements of the device according to the invention could also be carried out by hand.
