ten Flansch des Deckels unter den Flansch der Büchse herumbiegt. Alsdann treten gegeneinander greifende konische Biegewellen an den geformten Doppelflansch heran, biegen denselben abwärts und entfernen .sich wieder voneinander und von der Büchse, worauf die Fertigstellung des Schließrandes durch eine Falzrolle erfolgt.bends the flange of the cover under the flange of the sleeve. Then step Bend mutually engaging conical flexible shafts towards the formed double flange down and move away again from each other and from the rifle, whereupon the closing edge is completed by means of a folding roller.

Die Bewegung der konischen Biegerollen gegen- bezw. voneinander erfolgt gemäß vorliegender Erfindung mittels verschiebbarer Gleitstücke, die durch die Bohrung des hohl ausgebildeten Drehzapfens für den Werkzeugträger hindurchgeführt sind.The movement of the conical bending rollers against or. from each other takes place in accordance with the present Invention by means of slidable sliding pieces that pass through the bore of the hollow pivot pin for the tool carrier are passed through.

Der Erfindungsgegenstand ist auf der Zeichnung veranschaulicht, und zwar zeigt Fig. ι die wesentlichen Teile in Draufsicht, während Fig. 2, ein Schnitt nach der Linie x-x von Fig. i, den Antrieb und die Lagerung der Biegerollen, sowie deren Stellung zu der Büchse zeigt. Fig. 3 stellt eine Einzelheit dar. In den am oberen Ende des Maschinengestelles ι angebrachten Lagern 8 läuft eine senkrecht gerichtete Spindel 7. Die Spindel 7 trägt an ihrem unteren Ende einen Stempel 11, der beständig im Umlauf gehalten wird.The subject of the invention is illustrated in the drawing, namely Fig. Ι shows the essential parts in plan view, while Fig. 2, a section along the line xx of Fig. I, the drive and storage of the bending rollers, and their position on the sleeve shows. 3 shows a detail. A vertically directed spindle 7 runs in the bearings 8 attached to the upper end of the machine frame 1. The spindle 7 carries at its lower end a punch 11 which is constantly kept in circulation.

Der Stempel 11 wirkt mit einer Auflagerplatte 16 zusammen, die am oberen Ende der senkrecht gerichteten, in der Führung 18 verschiebbaren Spindel 17 angebracht ist. Die Auflagerplatte 16 erfährt für gewöhnlich keine Drehung, wird aber bei ihrer Aufwärtsbewegung, sobald die auf ihr befindliche Büchse gegen den Stempel 11 festgepreßt wird, von letzterem mitgenommen und in Umlauf versetzt. Um eine leichte Drehbarkeit des Auflagers 16 zu gestatten, ist dasselbe mit der Spindel 17 durch ein Rollenlager 27 verbunden (Fig. 2).The punch 11 cooperates with a support plate 16, which is at the upper end of the vertically directed, in the guide 18 displaceable spindle 17 is attached. the Support plate 16 does not usually experience any rotation, but when it moves upwards, as soon as the bushing on it is pressed tightly against the punch 11 is taken by the latter and put into circulation. To allow easy rotatability of the support 16 is the same connected to the spindle 17 by a roller bearing 27 (Fig. 2).

Die zum Verschließen der Büchse dienende Vorrichtung wird von einem Schlitten 29 getragen, der in Führungen 30 des Maschinengestelles verschiebbar ist und gegen die Klemmvorrichtung 11, 16 einstellbar ist. Diese Einstellbewegung des Schlittens erfolgt mittels einer Schwingwelle 31, deren Ansätze 32 in eine Nut 33 des Schlittens 29 eingreifen und welche mittels des Handgriffes 34 (Fig. 1) drehbar ist.The device used to close the can is carried by a slide 29, which is displaceable in guides 30 of the machine frame and can be adjusted against the clamping device 11, 16. This adjustment movement of the slide takes place by means of an oscillating shaft 31, the approaches 32 engage in a groove 33 of the carriage 29 and which by means of the handle 34 (Fig. 1) is rotatable.

An der Rückseite des Maschinengestelles ist in dem Schlitten 29 eine Welle 36 gelagert, die mit geringer Geschwindigkeit durch das Schneckenrad 37 angetrieben wird (Fig. ι und 3).On the back of the machine frame, a shaft 36 is mounted in the slide 29, which is driven at low speed by the worm wheel 37 (Fig. ι and 3).

Die Welle 36 kann eine fortlaufende oder absatzweise erfolgende Drehung erhalten. Bei dem dargestellten Ausführungsbeispiel erfolgtThe shaft 36 can be given continuous or intermittent rotation. at the illustrated embodiment takes place

Claims

the rotation of the shaft 36 intermittently by means of the transmission described below.

The shaft 36 carries a coupling sleeve 43 (Fig. 3), around which the worm wheel 37 loosely is rotatable, which receives a continuous rotation and has a coupling member 44, which cooperates with the coupling bolt 46, which is displaceable in a longitudinal groove 45 of the shaft 36 and by a Spring 47 is held in engagement with the coupling member 44. The coupling bolt 46 protrudes over the surface of the Shaft 36 protrudes and is provided with a transverse slot 48 in the Path of a releaser 49 attached to the slide 29 (FIGS. 1 and 3) lies and below the action of a spring 50 is available. The cooperating with the slot 48 of the coupling pin 46 The end of the releaser 49 is beveled and gradually enters the slot 48 as the shaft 36 rotates, whereby the coupling pin 46 is brought out of engagement with the coupling member 44 and the shaft 36 is stopped. The release of the releaser 49 out of engagement with the shaft 36 takes place in any way by a leverage or the like Art.

The shaft 36 carries three cam disks 71, 72 and 73, which are expediently made of one piece exist. In the middle part of the carriage 29 a hollow pin is mounted, around which the tool carrier 75 is rotatable. The tool carrier rotates by the roller 76 cooperating with the lifting disk 71. On the free one The tools are attached to the end of the tool carrier.

The tool carrier is provided with two lateral projections ] "] (FIG. 1), on the outer sides of which slide pieces are attached in guides 78, which carry the closing tools, the crimping roller 79 and the folding roller 84, respectively.

The third closing tool consists of two conical rollers 89 and 90, one of which lies above and the other below the path of the closing edge to be produced. These rollers take part in the horizontal rotary movement, but also receive a proper movement in the vertical direction, whereby they come closer to one another. be separated from each other. The lower roller 89 is mounted in the arm 91 loosely rotatably mounted on the inside of the guides ¹ J "] on the bolt 82nd In the rear fork-shaped end of the arm 91 rollers 92 are mounted in an annular groove 93 of a sleeve The upper roller 90 is loosely rotatably mounted in an arm 95 which is attached to the inner side of the arm 91, which is correspondingly cut out, on the bolt 82. In the rear fork-shaped end of the arm 95 are rollers 96 which engage in an annular groove 97 of a spindle 98 which is passed through the sleeve 94. The sleeve 94 is pushed into the hollow pivot pin in such a way that it does not join in the oscillating movement of the same.

A horizontal shaft 99, around which two levers 100 and 101 are loosely rotatable, in the ends of which rollers are mounted, which with the lifting disks 72 and 73 cooperate and held therewith by a spring 102 in engagement will. The lever 100 is provided with a protruding arm 103, the fork-shaped end carries rollers 104 which engage in an annular groove 105 of the bolt 98. The lever 101 is provided with an arm 106, whose fork-shaped end carries rollers 107 which are inserted into an annular groove 108 of the sleeve 94 intervention. The rollers 89 and 90 are given a movement by the parts mentioned in the vertical direction by the upward movement of the bolt 98 a corresponding Downward movement of the upper roller 90 and the downward movement of the sleeve 94 a corresponding Upward movement of the lower roller 89 causes. The position of the annular grooves 105 and 108 is corresponding to Adjustable position of the slide, for what purpose the neck rings 109 and 110 on the Bolts 98 are screwed on adjustable.

Godfather nt-A ν saying:

Can sealing machine with one around the pivot of a support swingable tool carrier, which one after the other a flanging roller, two conical bending rollers and a folding roller in the working position leads, characterized in that through the bore of the hollow pivot pin for the tool carrier mutually displaceable sliders are passed through the displacement of which the conical bending rollers (89, 90) are approached or removed from one another.
