PATENTAMT.PATENT OFFICE.
Bei Gerbereimaschinen, bei welchen Häute öder Felle auf einer drehbaren Segmenttrommel bearbeitet werden, ist es nothwendig, dafs die Häute oder Felle durch eine Klemmleiste, " welche auf die Längskante der Trommel drückt, gegenüber der Einwirkung der Werkzeuge festgehalten werden.In tannery machines, in which hides or skins on a rotating segment drum are processed, it is necessary that the hides or skins by a terminal strip, "which presses on the longitudinal edge of the drum, against the action of the tools be held.
Um Arbeit zu sparen, ist diese Klemmvorrichtung oder Zange selbstthätig gemacht, derart, dafs sie sich selbstthätig nach Ingangsetzung der Maschine und vor Einwirkung der Werkzeuge schliefst und umgekehrt auch selbstthätig' nach Einwirkung der Werkzeuge öffnet, so dafs die Bedienung der Maschine die Häute nur aufzulegen und abzunehmen hat.In order to save work, these clamping devices or pliers are made automatically, in such a way that that it is automatic after the machine has been started and before the tools work closes and vice versa also automatically opens after the action of the tools, so that the operator of the machine only has to put on and take off the skins.
Die Segmenttrommel C ist durch Zahnräder- etc. Antrieb um die Achse F drehbar; die Achse F ist rechts und links in zwei Lagerständern H gelagert. D ist die Werkzeugwalze. Bei A erhält die Segmenttrommel C eine Leiste mit Nuth, in welche die Gegenleiste B, welche sich in der rechts- und linksseitigen radialen Führung G verschieben kann, eingreift; diese beiden Leisten A und B bilden die Klemmvorrichtung oder Zange zum Festhalten der Haut. Rechts und links an den Stirnseiten hat die Leiste B zwei Rollen, welche sich in Curvennuthen E an den Lagerständern H führen. Bei Bewegung der Segmenttrommel in der Pfeilrichtung wird die Leiste B durch die in den Curvennuthen E laufenden Rollen radial vorwärts gegen die Leiste A bewegt und preist sich schliefslich, bevor noch die Segmenttrommel unter die Werkzeugwalze D gelangt, federnd fest gegen die Leiste A, wobei die zwischengelegte Haut festgeklemmt wird. Während nun die Trommel mit der Haut unter der Werkzeugwalze D durchgeführt und die Haut hierbei bearbeitet wird, laufen die Rollen der Klemmleiste B in dem concentrischen Theil der Curvennuthen E, so dafs also die Haut während des Arbeitsprocesses gleichmäfsig festgehalten ist. Bei Retoursteuerung der Segmenttrommel tritt der Vorgang ungekehrt ein und zuletzt wird die Klemmvorrichtung bezw. Zange wieder selbstthätig gelöst, so dafs die bearbeitete Haut herausgenommen und durch eine unbearbeitete Haut ersetzt werden kann. Eventuell kann auch die Trommel eine ganze Umdrehung (nur in der Pfeilrichtung) machen und ist dann nur eine entsprechende Fortsetzung und Form der Curvennuthen E nöthig.The segment drum C can be rotated about the axis F by means of a gear drive, etc.; the axis F is mounted in two bearing stands H on the right and left. D is the tool roll. At A , the segment drum C receives a bar with a groove in which the counter bar B, which can move in the right-hand and left-hand radial guide G , engages; these two strips A and B form the clamping device or forceps for holding the skin. The bar B has two rollers on the right and left on the front sides, which are guided in curve grooves E on the bearing stands H. When the segment drum moves in the direction of the arrow, the bar B is moved radially forwards against bar A by the rollers running in the curve grooves E and finally, before the segment drum gets under the tool roller D , it is resiliently fixed against bar A, whereby the interposed skin is clamped. While the drum with the skin is now passed under the tool roll D and the skin is being worked on, the rollers of the clamping bar B run in the concentric part of the curve grooves E, so that the skin is evenly held during the work process. With return control of the segment drum, the process occurs the other way round and finally the clamping device is respectively. Forceps released again automatically, so that the treated skin can be removed and replaced by an unworked skin. Possibly the drum can also make a complete revolution (only in the direction of the arrow) and then only a corresponding continuation and shape of the curve grooves E is necessary.
