Patentiert im Deutschen Reiche vom 2. September 1910 ab.Patented in the German Empire on September 2, 1910.
Die Erfindung bezieht sich auf Vorrichtungen zur Bildung des Bodenquadrats für Maschinen zur Herstellung von Kreuzbodenbeuteln, bei welchen der auf einem Falzblech befindliche Schlauch aufgesperrt und sodann von einem eingeführten Öffnungsfinger vollends geöffnet wird.The invention relates to devices for forming the floor square for machines for the production of cross-bottom bags in which the tube located on a folded sheet is unlocked and then is fully opened by an inserted opening finger.
Bei den bekannten Vorrichtungen dieser Art erfolgt das völlige Öffnen und UmlegenIn the known devices of this type, the complete opening and folding takes place
ίο des Schlauches durch einen Finger, dessen Eintritt in den Papierschlauch durch teilweises Aufsperren desselben oder durch Anheben des ganzen Beutelbodens ermöglicht wird. Die Bewegung des Fingers ist hierbei eine doppelte: einmal nach vorn und zum anderen von unten nach oben. Da bei diesen Vorrichtungen der Finger den Papierschlauch vollends aufsperren und ihn über den abgeschrägten Kopfteil des Falzbleches scharf umlegen muß, ist es bei schneller Arbeitsweise oft unvermeidlich, daß der Finger durch den Boden stößt und der Beutel mithin unbrauchbar ist, was besonders leicht bei brüchigem oder nicht starkem Papier der Fall ist.ίο the hose through a finger, whose Entry into the paper tube by partially unlocking it or by lifting it of the whole bottom of the bag is made possible. The movement of the finger is twofold: once forwards and forwards others from the bottom up. Since with these devices the finger touches the paper tube you have to unlock it completely and turn it over sharply over the beveled head part of the folding plate, this is the case with fast working methods it is often inevitable that the finger sticks through the bottom and the bag is consequently unusable, which is particularly easy is the case with paper that is brittle or not strong.
Bei dem Gegenstand der Erfindung dagegen werden die über dem abgeschrägten Kopfteil des Falzbleches vorstehenden Ecken des Schlauches durch auf und ab bewegbare FaIzplatten hochgekantet, während das vollständige öffnen und Umlegen des Schlauches durch einen lediglich parallel zum FalzblechIn the subject matter of the invention, however, the beveled head part of the folding plate protruding corners of the hose by folding plates that can be moved up and down Edged while fully opening and turning the hose by one only parallel to the folding plate
geführten Finger erfolgt. Durch das Zusammenarbeiten dieser Teile wird nicht nur eine Vereinfachung der Arbeitsweise der Papierbeutelmaschinen erzielt, sondern auch die Leistung derselben wesentlich gesteigert. Auch ist der Kraftbedarf ein geringerer, da der Finger nur zweierlei Bewegungen auszuführen hat und ferner nur einen kleinen Teil der Faltarbeit leistet, da die beiden Falzplatten die eigentliche Quadratfalte herstellen. Der Falzfinger drückt überdies nicht fest auf den Papierschlauch, sondern führt einige Millimeter höher in den durch die Falzplatten beim Knicken gebildeten Raum und schiebt so den oberen Teil des zu bearbeitenden Papierschlauches nach hinten und bildet das Bodenquadrat. Daher kann auch die Maschine bedeutend schneller arbeiten, ohne daß ein Zerreißen des Papierschlauches erfolgt.guided finger takes place. By working these parts together, it doesn't just become one Simplification of the operation of the paper bag machines achieved, but also the Performance of the same increased significantly. The power requirement is also lower, since the Finger has to perform only two movements and only a small part of the movement Folding work because the two folding plates produce the actual square fold. Of the Furthermore, the folding finger does not press firmly on the paper tube, but guides it for a few millimeters higher into the space formed by the folding plates when folding and thus pushes the upper part of the paper tube to be processed to the rear and forms the floor square. Therefore, the machine can also work significantly faster without tearing of the paper tube.
Eine Ausführungsform der Erfindung ist in der Zeichnung veranschaulicht, und zwar zeigt: Fig. 1 eine Seitenansicht mit teilweisem Schnitt, Fig. 2 eine Draufsicht. Die Wirkungsweise der neuen Vorrichtung ist folgende: Die auf der Welle d starr befestigten Zapfen c mit den Falzplatten b werden in bekannter Weise durch Exzenter gehoben und gesenkt. Die Falzplatten b schmiegen sich in ihrer zweckentsprechenden schrägen Lage dem Falzblech e genau seitlich an, wodurch auch ein Ausweichen aus der vorgeschriebenen Bahn verhindert wird. Der Finger α bewegt sichAn embodiment of the invention is illustrated in the drawing, namely: FIG. 1 is a side view with partial section, FIG. 2 is a plan view. The mode of operation of the new device is as follows: The pins c, which are rigidly attached to the shaft d, with the folding plates b are raised and lowered in a known manner by eccentrics. The folding plates b nestle in their appropriate inclined position to the folding plate e exactly laterally, which also prevents deviating from the prescribed path. The finger α moves
jetzt nur noch zwangsweise wagerecht in der Längsrichtung vorwärts. Wird durch die Exzenterbewegung die Welle d gehoben, so wird der auf dem Falzblech e befindliche Papierschlauch scharfkantig umgeschlagen und erfolgt durch die geradlinige Bewegung des Fingers α die Bildung des Bodenquadrats.now only compulsorily horizontally forward in the longitudinal direction. If the shaft d is raised by the eccentric movement, the paper tube located on the folding plate e is folded over with sharp edges and the straight movement of the finger α creates the floor square.
