Description

Die Erfindung bezieht sich auf mit Saugwirkung arbeitende Vorrichtungen, bei denen flach zusammengelegte Faltschachteln bzw. Faltschachtelmäntel aufgerichtet und in entgegengesetzter Richtung wieder flach gelegt werden, zu dem Zweck, die ursprünglich in der Fläche liegenden ungebrochenen Schachtelkanterb ebenfalls scharf zu brechen, um diesen die Spannung und damit der später in, Hohlform aufgerichteten Schachtel die Neigung zu nehmen, wieder in die ursprüngliche Flachform zurückzufallen. Gegenüber bekannten Vorrichtungen dieser Art bestecht das Neue der Erfindung . im wesentlichen darin, daB ein Sauger im einem fortlaufenden Arbeitsgang eine Breitseite der ihm zugeführten Flachschachtel von der gegenüberliegenden, vorübergehend festgehaltenen Breitseite abzieht, die hierdurch aufgerichtete Schachtel unter Knicken der bisher ungebrochenen Kanten in die entgegengesetzte Flachlage umlegt und sie einem Walzenpaar zuführt, das die nunmehr entgegengesetzt flachgelegte Schachtel in Richtung der Einpackmaschine weiter befördert und gleichzeitig die beiden neu gebildeten Kanten scharf zusammenpreßt und dadurch vollständig bricht. Die Erfindung verbindet mit einer einfachen und gedrungenen Bauart sowie zuverlässigen WirIkunesweise die Möglichkeit, daß der Vorgang des Auf richtens und Wiederflachlegens der Flachschachteln einen Teil einer ununterbrochenen Förderung der Flachschachteln zur Einpac'kmasahine bildet.The invention relates to devices operating with suction, in which flat folded boxes or folded box jackets are erected and be laid flat again in the opposite direction, for the purpose that Unbroken box edge originally lying on the surface, also sharp to break to this tension and thus the later erected in, hollow form Box to take the tendency to fall back into the original flat shape. Compared to known devices of this type, the novelty of the invention is impressive. in the essential in the fact that a suction cup has a broad side in one continuous operation the flat box fed to him from the opposite, temporarily held one Pulls off the broad side, the box erected as a result, buckling the previous one unbroken edges folded over in the opposite flat position and they a pair of rollers feeds that the now oppositely flattened box in the direction of Wrapping machine conveyed further and at the same time the two newly formed edges compresses sharply and thereby breaks completely. The invention connects with a simple and compact design as well as reliable functionality the possibility of that the process of erecting and flattening the flat boxes one Forms part of an uninterrupted promotion of flat boxes for Einpac'kmasahine.

Der Erfindungsgegenstand ist -auf der Zeichnung in einem Ausführungsbeispiel veranschaulicht. Fig. i zeigt die Vorrichtung in der Arbeitsstellung, die sie ,mach Einführung der Flachschachtel in ihrer ursprünglichen Flachlage einnimmt; Fig.2 zeigt die Vorrichtung in der Arbeitsstellung nach dem Umlegen der Schachtel in die entgegengesetzte Flachlage im Augenblick des Ei.nführensder letzteren in die Preßwalzen.The subject of the invention is -on the drawing in one embodiment illustrated. Fig. I shows the device in the working position that they do Introduction of the flat box in its original flat position; Fig. 2 shows the device in the working position after folding the box into the opposite flat position at the moment the latter is introduced into the press rolls.

Bei dem dargestellten Ausführungsbeispiel wird die Flachschachtel a durch ein ständig umlaufendes Walzenpaar 1, 2 der Fördereinrichtung unter Voraustauf der Karete b auf eine ortsfeste Tischplatte 3 befördert und von dieser mittels Saugluft an der unteren Breitseite b-d festgehalten. Gegenüber der Tischplatte 3 ist eine Saugplatte oder -leiste 6 angeordnet, die in einem Bogen so hin und her geschwungen wird, daB sie in der Stellung der Fig. i die obere Breitseite c-e der Flachschachtel erfaßt, diese bei ihrer Schwingbewegung nach der Stellung der Fig. 2 öffnet und sie unter Knickung der bis dahin in der Fläche liegenden Kanten c und d in die entgegengesetzte Flachlage umlegt, so daß die nunmehrige Vorderkante c auf die Walze 7 eines ständig umlaufenden Walzenpaares 7, 8 zu liegen kommt. Sobald dies geschieht, wird die Saugluft abgestellt und die umgelegte Flachschachtel von der Walze 8 erfaßt und u.ntter starker Anpressung an die Walze 7 nach einer Einpackvorrichtung hin weiter befördert, wobei dieKanten c undd zwischen dem Walzenpaar 7, 8 vollkommen gebrochen werden.In the illustrated embodiment, the flat box a by a constantly rotating pair of rollers 1, 2 of the conveyor under advance the Karete b conveyed to a stationary table top 3 and from this by means of suction air held on the lower broad side b-d. Opposite the table top 3 is a Suction plate or strip 6 arranged, which swung back and forth in an arc becomes that in the position of Fig. i the upper broad side c-e of the flat box detected, this opens with its oscillating movement according to the position of FIG. 2 and it with kinking of the edges c and d, which had been lying in the surface up to that point, into the opposite one Flat lay so that the now leading edge c on the roller 7 of a constantly rotating roller pair 7, 8 comes to rest. As soon as this happens, the suction air is released parked and the folded flat box detected by the roller 8 and u.ntter stronger Pressing against the roller 7 after a packing device is conveyed further, wherein the edges c and d between the pair of rollers 7, 8 are completely broken.

Im vorliegenden Fall wird dem Sauger 6 die erforderliche Hinundherschwingung dadurch erteilt, daß er an zwei Hebeln ,I, 5 angelenkt ist, die parallel zueinander aus der Stellung der Fig. i im die Stellung der Fig.2 und zurück geschwungen werden können. Die Länge der Hebel d und 5 entspricht der Breite der Schmalseiten der Flachschachtel, so daß der von den Schmalseiten beschriebene Weg und demit derjenige der Saugplatte 6 genau demjenigen entspricht, den die Breitseite c-e beim Umlegen der Flachschachtel aus der einem Flachlage in die andere beschreibt. In Fig. i ist dieser Weg durch zwei strichpunktierte Kreislinien dargestellt. Um die Schwingbewegung der Schmalseiten d-e und b-c zu ermöglichen, sind die oberen Walzen der Walzenpaare 1, 2 und 7, 8 halbzylindrisch ausgeführt.In the present case, the sucker 6 is given the required oscillation granted by the fact that it is articulated on two levers, I, 5, which are parallel to each other from the position of Fig. i in the position of Fig.2 and swung back can. The length of levers d and 5 corresponds to the width of the narrow sides of the flat box, so that the path described by the narrow sides and that of the suction plate 6 corresponds exactly to that which the broad side c-e when turning over the flat box describes from one flat position to the other. In Fig. I this path is through two dash-dotted circular lines shown. About the swinging movement of the narrow sides To enable d-e and b-c are the top rollers of roller pairs 1, 2 and 7, 8 semi-cylindrical.

Bei der dargestellten Ausführungsform sind die Naben der beiden Hebel q und 5 auf ihrem Umfang mit Zahnkränzen versehern und erhalten ihre gemeinsame Schwingbewegung durch ein in die Zahnkränze eingreifendes Zahnsegment 9, das durch eine ständig umlaufende Kurbel io über das Gestänge i i hin und her geschwungen wird.In the embodiment shown, the hubs are the two levers Provide q and 5 with sprockets on their circumference and maintain their joint Oscillating movement by a toothed segment 9 engaging in the ring gears, which is driven by a constantly rotating crank io swung back and forth over the linkage i i will.
