Description
Gegenstand der Erfindung ist eine Federtransporteinrichtung mit Servo-Antrieb nach dem Oberbegriff des Patentanspruchs 1, (siehe z.B. GB-A-1152 072).The invention relates to a spring transport device with servo drive according to the preamble of claim 1, (see e.g. GB-A-1152 072).
Derartige Maschinen dienen dazu, eine fertig hergestellte Feder verarbeitungsgerecht und lagengenau einer Einrichtung zuzuführen, in welcher Einrichtung die Federn zu einem Federkern, einem Polster oder einem Sitzkissen montiert werden.Such machines are used to make a finished Spring suitable for processing and in the exact position of a facility to supply in which facility the springs to one Innerspring, a cushion or a seat cushion become.
Merkmal einer derartigen Federeinlegestation ist, daß von einer Federherstellmaschine, die im Rahmen der vorliegenden Erfindung nicht mehr beschrieben wird, eine Feder in jeweils einer Greifhand eines mehrarmigen Transportsternes gefaßt wird und diese Feder nun über eine Federeinlegestation und verschiedene andere nachgeschaltete Stationen der Montagemaschine zugeführt wird.Characteristic of such a spring insertion station is that of a spring manufacturing machine, which is within the scope of the present Invention is no longer described, a spring in each a gripping hand of a multi-armed transport star is and this spring now via a spring insertion station and various other downstream stations of the Assembly machine is fed.
In einem auf den gleichen Anmelder zurückgehenden Patent nach der DE 34 16 110 C2 wurde eine Federherstellmaschine beschrieben, in der ebenfalls ein Transportstern vorhanden war.In a patent based on the same applicant DE 34 16 110 C2 became a spring manufacturing machine described in which there is also a transport star was.
Die jeweils in dieser Station hergestellte Feder wird in die jeweilige Greifhand des Transportsternes eingelegt und dort klemmend gefaßt und der Weiterverarbeitung zugeführt.The spring produced in this station is in the respective gripping hand of the transport star inserted and there clamped and sent for further processing.
Die sich daran anschließende Federeinlegestation funktioniert so, daß Schwenkbacken im Auslaufbereich der jeweiligen Greifhand des Transportsternes vorhanden waren, welche Schwenkbacken zwischen sich die Feder aufnahmen, wobei die Feder aus der Greifhand des Transportsternes in diese Schwenkbacken eingelegt wurden. Mit einer derartigen Schwenkbewegung der Aufnahmebacken im Bereich der Federeinlegestation bestand aber der Nachteil, daß die dort in die Federeinlegestation eingelegte Feder nie genau genug positoniert werden konnte. Dies war mit dem Nachteil verbunden, daß die Feder über eine größere Anzahl von nachfolgenden Richtstationen genau ausgerichtet werden mußte, was mit erhöhtem Maschinenaufwand verbunden war.The subsequent spring insertion station works so that swivel jaws in the outlet area of the respective Gripping hand of the transport star were present, which Swivel jaws between them take up the spring, the Spring from the gripping hand of the transport star into this Swivel jaws were inserted. With such a Swiveling movement of the jaws in the area of Spring insertion station, however, had the disadvantage that there spring inserted into the spring insertion station is never precise enough could be positioned. This was with the downside connected that the spring over a larger number of subsequent straightening stations had to be precisely aligned, which was associated with increased machine expenditure.
Bei der bekannten Anordnung des gleichen Anmelders war es nicht möglich, unterschiedliche Hübe des Bandantriebes zu fahren, und daher konnten die Federn nur mit gleichem Abstand voneinander zu der Transfereinrichtung transportiert werden. Damit bestand der Nachteil, daß erst im Bereich der am Schluß der Antriebskette angeordneten Transfereinrichtung der individuelle Abstand zwischen den Federn in der Transfereinrichtung eingestellt werden mußte, was mit einem hohen Maschinenaufwand und entsprechend hohen Herstellkosten für die Transfereinrichtung verbunden war.In the known arrangement of the same applicant, it was not possible to different strokes of the belt drive drive, and therefore the springs could only with the same distance are transported from one another to the transfer device. This was the disadvantage that only in the area at the end the drive chain arranged transfer device individual distance between the springs in the Transfer device had to be set, what with a high machine expenditure and correspondingly high manufacturing costs was connected to the transfer facility.
Der Erfindung liegt deshalb die Aufgabe zugrunde eine Federtransporteinrichtung der eingangs genannten Art so weiter zu bilden, daß die gesamte Transporteinrichtung kostengünstiger ausgestaltet werden kann, insbesondere mit dem Ziel, daß auch die individuelle Einstellung des Abstandes zwischen den einzelnen Federn mit einfachen Mitteln einstellbar ist.The invention is therefore based on the object Spring transport device of the type mentioned above continue to form that the entire transport facility can be designed more cost-effectively, in particular with the goal that also the individual adjustment of the distance between the individual springs with simple means is adjustable.
Zur Lösung der gestellten Aufgabe ist die Erfindung durch die technische Lehre des Anspruches 1 gekennzeichnet.To achieve the object, the invention is by characterized technical teaching of claim 1.
Wesentliches Merkmal der Erfindung ist, daß von einem zentralen Antrieb ausgehend zwei synchron angetriebene Bandschleifen vorhanden sind, wobei jede Bandschleife ein oberes und ein unteres Trum ausbildet und daß die zu transportierende Feder jeweils in die einander zugewandten Trums der beiden synchron angelegten Bandschleifen klemmend eingelegt wird und unter Kompression transportiert wird.An essential feature of the invention is that of one central drive based on two synchronously driven Ribbon loops are present, with each ribbon loop one forms upper and a lower run and that the to transporting spring in the facing each other Trums of the two synchronously arranged ribbon loops clamping is inserted and transported under compression.
Weiteres Merkmal ist, daß der Antrieb als Servo-Antrieb ausgebildet ist oder wahlweise als Schrittmotor, wodurch es nun erstmals möglich ist, im Bereich der Einlegestation die Feder so einzulegen, daß man einen konstanten Einlegezyklus hat und das Band aber unterschiedlich schnell transportiert um somit unterschiedliche und individuell einstellbare Abstände zwischen den einzelnen Federn zu erhalten.Another feature is that the drive is a servo drive is designed or optionally as a stepper motor, which makes it is now possible for the first time in the area of the insertion station Insert the spring so that you have a constant loading cycle and has transported the belt at different speeds so different and individually adjustable To maintain distances between the individual springs.
Stand der Technik war hierbei eine mechanische Antriebsverbindung zwischen dem Transportstern und der nachgeschalteten Federtransporteinrichtung, was mit dem Nachteil verbunden war, daß nur konstante Hübe und dementsprechend ein konstanter Abstand der einzelnen Federn voneinander eingestellt werden konnte.The prior art was mechanical Drive connection between the transport star and the downstream spring transport device, what with the The disadvantage was that only constant strokes and accordingly a constant distance between the individual springs could be adjusted from each other.
Hier setzt die Erfindung ein, die vorsieht, daß nun mit einfachen Mitteln individuelle Abstände zwischen den Federn hergestellt werden können. Dies erfolgt durch das Ansteuern des Antriebs, so daß der Hub bzw. der Vorschub für jede erfasste Feder einzeln und genau eingestellt werden kann.This is where the invention comes in, which now provides that simple means individual distances between the springs can be produced. This is done by actuation of the drive, so that the stroke or the feed for each detected spring can be adjusted individually and precisely.
Dies vereinfacht die am Ende der Federtransporteinrichtung angeordnete Transfereinrichtung in hohem Maße.This simplifies that at the end of the spring transport device arranged transfer device to a high degree.
Diese Transfereinrichtung muß deshalb nun nicht mehr die Federn individuell nachträglich ausrichten, sondern sie erhält die bereits schon individuell ausgerichteten Federn mit ihren jeweiligen Federabständen lagenrichtig zugeteilt, so daß nur noch ein einfaches Schiebersystem dafür sorgt, daß eine Reihe von Federn, die bereits schon lagenrichtig der Transfereinrichtung zugeführt werden einer nachgeschalteten Montagemaschine übergeben werden. This transfer device therefore no longer has to Align springs individually afterwards, but instead receives the already individually aligned springs with their respective spring spacing allocated correctly so that only a simple slide system ensures that a series of springs that are already in the correct position Transfer device are fed a downstream Assembly machine to be handed over.
