Description

Elektrische Stoffzuschneidemaschine mit Messerschärfvorrichtung. Es ist bekannt, an elektrischen Stoffzuschneidemaschinen zum Schärfen des Kreismessers während des Betriebes kleine Schleifscheiben anzuordnen, die zeitweise mechanisch an das Messer herangeführt werden können. Gegenüber bekannten Vorrichtungen dieser Art zeichnet sich die den Gegenstand der Erfindung bildende Messerschärfvorrichtung dadurch aus, daß besondere Vorkehrungen getroffen sind, um die Schleifscheiben der Abnutzung des Messers entsprechend einstellen zu können und ihre Lage derjenigen des Messers genau anzupassen.Electric fabric cutting machine with knife sharpening device. It is known on electric fabric cutting machines for sharpening the circular knife to arrange small grinding wheels during operation, at times mechanically can be brought up to the knife. Compared to known devices this Type is characterized by the knife sharpening device forming the subject of the invention characterized in that special precautions are taken to protect the grinding wheels of the Adjust the wear of the knife accordingly to be able to and theirs Adjust the position of the knife exactly.

Die Anpassung der Schleifscheiben an das Messer ihrer Lage nach ist dadurch ermöglicht, daß die Schleifscheiben sowohl nach zwei aufeinander senkrechten Richtungen verschoben als auch um eine in der Verschiebungsebene liegende Achse geschwenkt werden können. Zu diesem Zweck werden die Schleifscheiben an den Hebel, mit dem sie an das Messer herangeführt werden können, mittels einer Gabel befestigt, die mittels eines Zapfens in Richtung der Zapfenachse verstellbar und um die Achse selbst schwenkbar ist, während die Schleifscheiben in der Gabel mit Hilfe ihrer Achse seitlich einstellbar sind.The adjustment of the grinding wheels to the knife according to their position is thereby made possible that the grinding wheels both after two mutually perpendicular Shifted directions as well as about an axis lying in the shift plane can be swiveled. For this purpose, the grinding wheels are attached to the lever, with which they can be brought to the knife, attached by means of a fork, adjustable by means of a pin in the direction of the pin axis and around the axis itself is pivotable, while the grinding wheels in the fork with the help of their Axis can be adjusted laterally.

Zum Ausgleich der Messerabnutzung ist zwischen die Gabel, die die Schleifscheiben trägt, und den Hebel zum Bewegen der Schleifscheiben ein einstellbarer Schwenkarm eingeschaltet.To compensate for the knife wear is between the fork, which the Bears grinding wheels, and the lever for moving the grinding wheels an adjustable Swivel arm switched on.

Auf der Zeichnung ist der untere Teil einer elektrischen Stoffzuschneidemaschine mit Kreismesser dargestellt, bei der die neue Messerschärfvorrichtung in einer Ausführungsform angebracht ist.On the drawing is the lower part of an electric fabric cutting machine Shown with a circular knife, in which the new knife sharpening device in one embodiment is appropriate.

Abb. i und :2 stellen das 'Maschinenunterteil in Seiten- und Vorderansicht dar, und Abb. 3 zeigt in Vorderansicht die Schleifscheiben und ihre Befestigung für sich allein. Auf der Grundplatte i der Stoffzuschneidemaschine sitzt fest der Ständer 2. Ain Ständer sind der Motor 3 und das Messer 4. in bekannter Weise senkrecht verschiebbar, um bei Abnutzung des Messers dieses bis in die Fußplatte i senken zu können.Fig. I and: 2 show the machine base in side and front view and Fig. 3 shows a front view of the grinding wheels and their attachment for yourself. The is firmly seated on the base plate i of the fabric cutting machine Stand 2. A stand, the motor 3 and the knife 4. are vertical in a known manner can be moved so that when the knife is worn it can be lowered into the footplate i to be able to.

Am Ständer 2 ist in einem Bock 5 der Hebel 6 gelagert, der die Schleifscheiben 7 trägt. Das hintere Hebelende 8 hat einen Fingergriff 9. Am vorderen Ende io des Hebels 6 ist drehbar ein Arm i i angelenkt. Dieser kann mittels einer Schraube 12 in seiner jeweiligen Lage festgeklemmt werden. Das vordere Ende des Armes i i ist gegabelt (Abb. 3). In die Gabelung ist ein Zapfen 13 an einem U-förmigen Träger 14 eingesetzt, in dessen Enden die Schleifscheiben 7 gelagert sind. Eine Schraube 15 dient zum Festklemmen des Zapfens 13 in seiner jeweiligen Lage. Die Achsender Schleifscheiben 7 sind mit Gewinde versehen und können mit Hilfe von Muttern 16 festgeklemmt werden, nachdein die Schleifscheiben in ihre richtige Seitenlage eingestellt sind.On the stand 2, the lever 6 is mounted in a bracket 5, which the grinding wheels 7 wears. The rear end of the lever 8 has a finger grip 9. At the front end io des Lever 6 is rotatably hinged to an arm i i. This can by means of a screw 12 be clamped in its respective position. The front end of the arm i i is forked (Fig. 3). In the fork is a pin 13 on a U-shaped support 14 used, in the ends of which the grinding wheels 7 are mounted. A screw 15 is used to clamp the pin 13 in its respective position. The axle transmitter Grinding wheels 7 are provided with threads and can with the help of nuts 16 must be clamped after you have set the grinding wheels in their correct lateral position are.

Vor den Schleifscheiben und dem Messer ist eine bekannte Schutzschiene 17 angebracht, die von einem Arm 18 getragen wird und in einer Führung i9 am unteren Ende des Armes 18 mittels eines Handgriffes 2o in der Höhe verstellt werden kann. Zum Festklemmen der Schiene in der gewünschten Lage dient eine Klemmschraube 21.There is a well-known guard rail in front of the grinding wheels and the knife 17 attached, which is carried by an arm 18 and in a guide i9 on the lower The end of the arm 18 can be adjusted in height by means of a handle 2o. A clamping screw 21 is used to clamp the rail in the desired position.

Will man das Messer .I schärfen, so braucht man nur mit einem Finger den Griff 9 des hinteren Hebelendes 8 zu erfassen und gegen eine Feder 22 emporzuziehen. Dann senken sich die Schleifscheiben 7, bis sie das Messer berühren. Mit Hilfe des Zapfens 13 und der verstellbaren Achsen der Schleifscheiben 7 kann man die Schleifscheiben genau der Messerkante anpassen, und zwar kann inan sie nach zueinander senkrechten Achsen verschieben und außerdem um den Zapfen 13 drehen. Ist die Messerabnutzung weiter vorgeschritten, so kann durch Schwenken des Armes i i um die Schraube 12 eine tTaclistelhing auf dieMesserachse zu erfolgen, ohne daß es nötig ist, die Einstellung der Schleifscheiben zii verändern.If you want to sharpen the knife .I, you only need one finger to grasp the handle 9 of the rear end of the lever 8 and pull it up against a spring 22. Then the grinding wheels 7 lower until they touch the knife. With the help of Pin 13 and the adjustable axes of the grinding wheels 7 can be the grinding wheels adjust exactly to the knife edge, namely inan they can be perpendicular to each other Shift axes and also rotate around pin 13. Is the knife wear If further progress is made, pivoting the arm i i around the screw 12 a tTaclistelhing to be done on the knife axis without it being necessary to change the setting change the grinding wheels zii.
