Description
Niederhalter an Scheren mit Fingerschutzeinrichtung Mit Rücksicht auf Unebenheiten und auf die wellige Beschaffenheit gewalzter Bleche ist der Hub de? Blechniederhalters verhältnismäßig groß zu wählen, so daß die Möglichkeit besteht, daß der Arbeiter in den Lichtraum zwischen Tisch und Niederhalter faßt und mit den Händen in den Bereich der Schermesser kommt. Die Folgen davon sind verhältnismäßig häufige Unfälle, die bis jetzt noch nicht wirksam vermieden werden konnten.Hold-down device on scissors with finger protection device With consideration on unevenness and on the wavy texture of rolled sheets is the stroke de? To choose sheet metal hold-down relatively large, so that there is the possibility of that the worker reaches into the light space between the table and the hold-down device and with the Hands in the area of the cutter. The consequences of this are proportionate frequent accidents that have not yet been effectively avoided.
Die Vermeidung dieses Nachteils ist Zweck der vorliegenden Erfindung. Das Wesen derselben besteht in der Anordnung einer unter dem Einfluß ihres Eigengewichtes oder Federdruckes auf den Tisch sich auflegenden Schutzschiene, die das Einschieben des Bleches zwar gestattet, den Raum zwischen Tisch und Niederhalter und damit den Arbeitsbereich der Messer gegen unbefugtes Hineinlangen abschließt.The purpose of the present invention is to avoid this disadvantage. The essence of these consists in the arrangement of one under the influence of its own weight or spring pressure on the table resting on the protective rail, which prevents the insertion of the sheet, the space between the table and the hold-down device and thus the The working area of the knife closes off unauthorized people.
In der Zeichnung ist der Erfindungsgegenstand beispielsweise in Abb. i im senkrechten Schnitt und in zwei verschiedenen Arbeitslagen (gehobener und gesenkter Stellung des Niederhalters) in Abb. 2 veranschaulicht.In the drawing, the subject matter of the invention is shown, for example, in Fig. i in vertical cut and in two different working positions (raised and lowered Position of the hold-down device) in Fig. 2.
Gemäß der Zeichnung bezeichnet T den Tisch der Maschine, U das Untermesser, 0 das Obermesser, N den Niederhalter. Der Tisch steht mit dem Untermesser fest, während sowohl der Messerbalken mit dem Obermesser, als auch der Niederhalter vertikal beweglich sind. Zum Abschließen des Lichtraumes zwischen Tisch und Niederhalter ist nunmehr eine Schutzschiene A angeordnet, die am Niederhalter am Bolzen B pendelt und, wie aus Abb. 2 zu ersehen ist, das Einschieben des Bleches zuläßt. Diese Schiene hebt sich beim Einschieben der Bleche nur so weit, als es die Blechdicke und die Unebenheiten des Bleches mit sieh bringen. Sie gestattet aber nicht, mit den Händen in den Bereich der Messer zu gelangen.According to the drawing, T denotes the table of the machine, U the lower knife, 0 the upper knife, N the hold-down. The table is fixed with the lower knife, while both the cutter bar with the upper cutter and the hold-down clamp are vertical are movable. To close off the clearance between the table and the hold-down device A protective rail A is now arranged, which oscillates on the bolt B on the hold-down device and, as can be seen from Fig. 2, allows the sheet metal to be pushed in. This rail when the sheet is pushed in, it only rises as far as the sheet thickness and the Bring unevenness of the sheet with you. But she does not allow using her hands to get into the area of the knives.
In Anbetracht der Einfachheit der Anordnung und der unbedingten Zuverlässigkeit gegen Unfälle stellt die Konstruktion einen wesentlichen Fortschritt in technischer und wirtschaftlicher Beziehung dar, der um so größer demjenigen erscheint, der die Unfallstatistiken der Berufsgenossenschaften bezüglich der Unfälle an Scheren aller Art verfolgt.Considering the simplicity of the arrangement and the absolute reliability against accidents, the construction represents a significant advance in technical and economic relationship, which appears all the greater to one who has the Accident statistics from the employers' liability insurance association with regard to all scissors accidents Kind of haunted.
