Description
er ein Abfallband aus einer Formmaschine heraus- und von dieser wegführt, ohne daß gleichzeitig die Behälteraustragung behindert wird.he leads a scrap tape out of a molding machine and away from it without simultaneously having the Container discharge is hindered.
Ein Ausführungsbeispiel des Erfindung !gegenstandes soll anhand der Zeichnungen beschrieben werden. Es zeigtAn embodiment of the invention! Subject will be described with reference to the drawings. It shows
F i g. 1 eine schematische Draufsicht einer Formmaschine, bei der die Abfall-Austragvorrichtuwg gemäß der Erfindung zur Anwendung kommt,F i g. 1 is a schematic plan view of a molding machine in which the waste discharge device according to FIG Invention is used,
F i g. 2 ?:ne Seitenansicht der in F i g. 1 gezeigten Formmaschine undF i g. 2?: Ne side view of the in FIG. 1 shown Molding machine and
F i g. 3 eine Seitenansicht der Abfall-Austragvorrichtung in vergrößerten! Maßstab.F i g. 3 is a side view of the garbage discharge device in enlarged! Scale.
Die in den Fig.) und 2 schematisch dargestellte, kontinuierlich arbeitende, im ganzen mit 10 bezeichnete Formmaschine zur Herstellung von Kunststoffbehältern besteht im wesentlichen aus einer Vorratsstation 12, in eier vorzugsweise zwei Rollen 14 mit aufgewickeltem Kunststoffband 16 gelagert sind, die nacheinander in der Formmaschine 42 der Formstation 40 verarbeitet werden, einer einen Teil der Vorratsstation bildenden Ladestation 15, in der die Rollen 14 vor ihrer Verarbeitung aufgenommen sind, einer Bandabziehvorrichtung 18, in die das führende Ende des Kunststoffbandes eingeführt und von mehreren Bandabziehwalzen 20 mit der gewünschten, auf die anderen Arbeitsstationen abgestimmten Geschwindigkeit weitergeförc ?rt wird, einer Zuführvorrichtung 22, die das Kunststoffband 16 von der Bandabziehvorrichtung 18 übernimmt und es der Formmaschine 42 zuführt, sowie einer neber der Formmaschine 42 angeordneten Abfall-Austragvorrichtung, die im ganzen mit 44 bezeichnet ist und den Gegenstand der Erfindung bildet.The continuously operating one shown schematically in FIGS.) And 2, designated as a whole by 10 Molding machine for the production of plastic containers consists essentially of a storage station 12, in eier preferably two rolls 14 are stored with wound plastic tape 16, which are successively in the Forming machine 42 of the forming station 40 are processed, a part of the supply station forming Loading station 15, in which the rolls 14 are received before they are processed, a tape pulling device 18, into which the leading end of the plastic tape is inserted and from several tape pull-off rollers 20 continued conveying at the desired speed coordinated with the other workstations, a feed device 22, which takes over the plastic tape 16 from the tape pulling device 18 and it the molding machine 42 supplies, as well as a next to the Forming machine 42 arranged waste discharge device, which is designated as a whole by 44 and the Forms the subject of the invention.
Das Abfallaustragrad 44 weist eine auf einer Welle 294 gelagerte zackenradförmige Xreisplatte 292 auf, die synchron zur Formmaschine 42 angetrieben ist. Die Drehrichtung der Kreisplatte 292 ist entgegengesetzt zu der der Formmaschine 42 gerichtet. Die Platte 292 weist feststehende Greifplatten 2% und zu diesen hin- und fortbewegliche Greifplatten 298 auf, die jeweils mitThe waste discharge wheel 44 has a toothed wheel-shaped rice plate 292 mounted on a shaft 294, which is driven synchronously with the molding machine 42. The direction of rotation of the circular plate 292 is opposite to that of the molding machine 42 is directed. The plate 292 has fixed gripping plates 2% and to these and back movable gripping plates 298, each with
ίο fluchtend zueinander ausgerichteten Greiffingern 300 bzw. 302 versehen sind. Die beweglichen Greifplatten 298 sind in Längsrichtung der Welle 294 durch eine Kurvenbahn und eine daran angreifende Abtastanordnung (nicht dargestellt) beweglich, um die Greiffinger 302 der beweglichen Greifplatten 298 mit den Greiffingern 300 der feststehenden Greifplatten 296 in Eingriff zu bringen. Das Abfallband 5 wird von den sich drehenden Greiffingerpaaren 300, 302 erfaßt und aus der Formmaschine 42 entfernt. Eine feststehend angeordnete Abstreifplatte 304 erstreckt sich um die obere Umfangshälfte des Abfallaustragrades 44 und dient dazu, das Abfallband 5 von den sich drehenden Greiffingerpaaren 300,302 abzustreifen, so daß es durch sein Eigengewicht in einen Granulator oder dergleichen gelangen kann.ίο gripper fingers 300 aligned with one another and 302 are provided. The movable gripping plates 298 are in the longitudinal direction of the shaft 294 by a Cam track and a scanning arrangement (not shown) acting on it movable to the gripping fingers 302 of the movable gripping plates 298 with the gripping fingers 300 of the stationary gripping plates 296 in To bring intervention. The waste tape 5 is gripped by the rotating pairs of gripper fingers 300, 302 and out of the molding machine 42 removed. A fixed stripper plate 304 extends around the upper peripheral half of the waste discharge wheel 44 and serves to remove the waste belt 5 from the rotating Pairs of gripping fingers 300,302 to be wiped off, so that it is in a granulator or the like by its own weight can get.
Das Abfallaustragrad 44 ist so neben der Formmaschine 42 angeordnet, daß das Abfallband S an einei Stelle aus der Maschine entfernt wird, bevor die fertigen Behälter aus der Maschine ausgestoßen werden, um so mit Sicherheit eine Behinderung der Behälteraustragung zu vermeiden.The waste discharge wheel 44 is arranged next to the molding machine 42 that the waste belt S to one Body is removed from the machine before the finished containers are ejected from the machine so as to to avoid an obstruction of the container discharge with certainty.
