Die Erfindung bezieht sich auf eine Zuführungsvorrichtung für drehrunde, hutförmige Werkstücke mit einem nach außen vorstehenden scheibenförmigen Rande, bei der die auf dem umlaufenden Boden einer feststehenden Trommel ruhenden, durch Zentrifugalkraft an den Rand der Trommelzarge geführten Werkstücke gegen ein am inneren Rande der TiOmmelzarge sitzendes festes Bogenstück bewegtThe invention relates to a feed device for rotating, hat-shaped Workpieces with an outwardly protruding disc-shaped edge, in which the on the rotating bottom of a stationary drum resting, by centrifugal force on the Edge of the drum frame guided workpieces against a on the inner edge of the TiOmmelzarge seated fixed bow piece moves

Solche Zuführvorrichtungen sind im wesentlichen bekannt. Die die neue Erfindung ausmachende besondere Ausgestaltung besteht darin, daß die Anprall- und Ablenkungsflächen des Bogenstückes in verschiedener Höhe übereinander angeordnet sind und sich in der Horizontalprojektion nach vorn überschneiden, so daß die in richtiger Lage ankommenden Werkstücke mit ihrem auf dem umlaufenden Boden ruhenden scheibenförmigen Rande oder ihrem hutförinigen Teile in bekannter Weise gegen die untere Ablenkungsfläche anlaufen und von dieser nach außen geführt werden, wogegen die umgekehrt liegenden Werkstücke an ihrem scheibenförmigen Rande von der oberen Ablenkungsfläche aufgefangen und in das Innere der Trommel zurückgeführt werden. Durch diese. Neuerung wird eine bedeutend sicherere Wirkungsweise der Zuführvorrichtung erreicht, so daß ein Versagen derselben fast ausgeschlossen ist. .Such feeding devices are essentially known. The one that defines the new invention special design is that the impact and deflection surfaces of the arc piece are arranged one above the other at different heights and are in the horizontal projection overlap forward so that the workpieces arriving in the correct position with their on the surrounding floor resting disc-shaped edge or its hat-shaped parts in a known manner against the run up to the lower deflection surface and be guided outwards by this, on the other hand the inverted workpieces are caught at their disc-shaped edge by the upper deflection surface and into the interior returned to the drum. Through this. The innovation will be a significantly safer one Effectiveness of the feeding device achieved, so that a failure of the same is almost impossible is. .

Auf der.Zeichnung ist der Erfindungsgegenstand in zwei Ausführungsbeispielen veranschaulicht. Es zeigt Fig. 1 das erste Ausführungsbeispiel in einem lotrechten, diametral durch die Trommel gelegten Schnitt, Fig. 2 die Trommel in einer Unteransicht, Fig. 3 die Austrittsstelle der Trommel, ebenfalls in Unteransicht, Fig. 3a einen Schnitt nach A-A der Fig. 2, in Richtung des Pfeiles gesehen, und Fig. 3b einen Schnitt nach Linie B-B der Fig. 3, in Richtung des Pfeiles gesehen. Fig. 4 veranschaulicht die Trommel des zweiten Ausführungsbeispieles in Unteransicht, Fig. 5 eine Teilansicht der Trommel und Fig. 5a einen Schnitt nach Linie C-C der Fig. 5, wieder in Richtung des Pfeiles gesehen. The subject of the invention is illustrated in two exemplary embodiments on the drawing. 1 shows the first exemplary embodiment in a vertical, diametrically cut section through the drum, FIG. 2 shows the drum in a view from below, FIG. 3 shows the exit point of the drum, also in a view from below, FIG. 3a shows a section along AA of FIG. 2, seen in the direction of the arrow, and FIG. 3b shows a section along line BB of FIG. 3, seen in the direction of the arrow. FIG. 4 illustrates the drum of the second exemplary embodiment in a view from below, FIG. 5 shows a partial view of the drum and FIG. 5a shows a section along line CC of FIG. 5, again seen in the direction of the arrow.

Im ersten Ausführungsbeispiele ist a die feststehende Trommel und b der umlaufende Boden derselben. An der Zarge ist ein nach innen vorstehender Rand c vorgesehen, dessen Abstand von dem Boden b etwa gleich der Höhe der Werkstücke ist, so daß diese, wenn sie auf dem Boden aufliegen, bei ihrer durch die Zentrifugalkraft verursachten Bewegung gegen die Trommelwand sich unter diesen Rand c schieben und unter diesem in der Drehrichtung des In the first exemplary embodiment, a is the stationary drum and b is the rotating base of the same. An inwardly protruding edge c is provided on the frame, the distance of which from the bottom b is approximately equal to the height of the workpieces, so that when they rest on the bottom, when they move against the drum wall caused by the centrifugal force, they are underneath them Slide edge c underneath it in the direction of rotation of the

Claims

Floor b are moved further. The workpieces lying with their disc-shaped edge on the floor, i.e. in the correct position, slide with this edge into a gap left between the drum frame and the floor. In the lower edge of the frame of the drum a groove d is incorporated, the depth of which is adapted to the height of the hat-shaped part of the workpieces. This groove d stands

ίο through an inlet opening c, which is designed according to the shape of the workpieces and which is inclined outwards, in connection with the inside of the drum, so that the correctly positioned workpieces can enter them and are then moved further by the movement of the bottom b until they are tangential connected discharge channel f arrive from the. they are forwarded to the workplace. In front of the inlet opening e , the workpieces moved along the drum wall through the circumferential base b collide against a fixed curved piece g with a plate h screwed onto it, which is seated on the inner edge of the drum frame. Two deflection surfaces i and k , which are arranged one above the other and which intersect in the horizontal projection towards the front, are provided on these parts.

If the workpieces come in the correct position, d. H.

■ with their disc-shaped edge resting on the circumferential bottom b , to the inlet opening, they run with the mentioned edge against the lowest deflection surface i on the plate h and are then guided outwards by this into the groove d in the lower frame edge

(Fig. 2). .. '..

But if the workpieces are upside down, i. H.

with their disk-shaped edge upwards, sq. they hit with this edge against the upper deflection surface k (FIGS. 3 and 3b). They are caught by the latter and returned to the inside of the drum. The incorrectly positioned workpieces are therefore safely diverted from the inlet opening, so that clogging of the same by incorrectly positioned workpieces and thus failure of the device is excluded.

The second embodiment according to FIGS. 4, 5 and 5a differs from the first described only in that both deflection surfaces I ₁ and A _{1 are} attached to the fixed arcuate piece g, so that the lower deflection surface I ₁ does not reach down to the surrounding floor b . Both surfaces are arranged one above the other at different heights and overlap in the horizontal projection towards the front. If the workpieces are in the correct position at the inlet e, the lowest deflection surface I ₁ again causes the workpiece to be guided outwards into the groove d, but now the deflection surface I ₁ acts on the hat-shaped part ■ of the workpiece (Fig. 4 ). The incorrectly positioned workpieces are again guided back into the interior of the drum through the upper deflection surface k _x by the action of the same on the disk-shaped edge of the workpiece (FIG. 5). -
