Description

Ausführungsbeispielembodiment

Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden. In Fig. 1 ist eine Seitenansicht des Magazins, der Wippe, der Vieleckrolle und der Vereinzelungstrommel im Schnitt dargestellt.The invention will be explained in more detail below using an exemplary embodiment. In Fig. 1 is a side view of the magazine, the rocker, the polygonal roller and the singling drum is shown in section.

An einem Magazin 1, in dem sich die Werkstücke 2 befinden, ist am Ausgang eine Wippe 3 angebracht, deren Ausleger auf einer Vieleckrolle 4 aufliegt. Neben der Vieleckrolle 4 befindet sich die Vereinzelungstrommel 5. Die Vieleckrolle 4 erstreckt sich zweckmäßigerweise nicht über die ganze Breite, sondern besteht aus mehreren auf einer gemeinsamen Achse befindlichen Segmenten, die in synchroner Ausrichtung angeordnet sind. Der Ausleger weist an seiner Unterseite eine Rolle auf, wobei der durch die Blechstärke oder durch ein zusätzlich angebrachtes Blech gebildete Anschlag am Ausiegerende in seiner Höhe mindestens dem Durchmesser des stangenförmigen Werkstückes 2 entspricht. Die Länge des Auslegers ist so bemessen, daß sich diese bis zur Senkrechten durch den Drehpunkt der Vieleckrolle 4 erstreckt. Der Auflagepunkt des Auflegers auf der Vieleckrolle 4 liegt unterhalb der Waagerechten durch den Mittelpunkt der Vereinzelungstrommel 5. Der Abstand zwischen der Senkrechten durch die Mittelpunkte der Vereinzelungstrommel 5 und der Vieleckrolle 4 ist kleiner als die Summe aus dem Radius der Vereinzelungstrommel 5 plus dem Inkreis der Vieleckrolle 4On a magazine 1, in which the workpieces are 2, a rocker 3 is mounted at the output, the boom rests on a polygonal roller 4. In addition to the polygonal roller 4 is the singling drum 5. The polygonal roller 4 expediently does not extend over the entire width, but consists of several located on a common axis segments, which are arranged in synchronous alignment. The boom has a roller on its underside, wherein the stop formed by the sheet thickness or by an additionally mounted sheet at the end of the discharge corresponds in height to at least the diameter of the rod-shaped workpiece 2. The length of the boom is dimensioned so that it extends to the vertical through the pivot point of the polygonal roller 4. The support point of the feeder on the polygonal roller 4 is below the horizontal through the center of the singling drum 5. The distance between the vertical through the centers of the singling drum 5 and the polygonal roller 4 is smaller than the sum of the radius of the singling drum 5 plus the inscribed circle of the polygonal roller 4

Die Wirkungsweise der Vorrichtung ist folgende: The operation of the device is the following:

Die im Magazin 1 befindlichen Werkstücke 2 gelangen über die Wippe 3 mit Ausleger und über die Vieleckrolle 4 in die am äußeren Umfang der Vereinzelungstrommel 5 befindlichen Längsnuten. Die Vieleckrolle 4 und die Vereinzelungstrommel 5 rotieren in entgegengesetzter Richtung. Durch die Ecken der Vieleckrolle 4 wird die Wippe 3 nach oben und unten bewegt und die Werkstücke werden vorpositioniert. Gleichzeitig werden die Werkstücke 2 gegen den Anschlag der Wippe 3 gedrückt und endgültig ausgerichtet, so daß sie ohne Verklemmen oder Verformen in die Längsnuten der Vereinzelungsrolle 4 gelangen können.The located in the magazine 1 workpieces 2 get over the rocker 3 with boom and the polygonal roller 4 in the located on the outer periphery of the singulating drum 5 longitudinal grooves. The polygonal roller 4 and the singling drum 5 rotate in the opposite direction. Through the corners of the polygonal roller 4, the rocker 3 is moved up and down and the workpieces are pre-positioned. At the same time the workpieces 2 are pressed against the stop of the rocker 3 and finally aligned so that they can get into the longitudinal grooves of the separating roller 4 without jamming or deformation.

2. Device according to item 1, characterized in that the boom is provided with a roller on its underside, which rests on the polygonal roller (4).

3. Device according to item 1 and 2, characterized in that the length of the arm is dimensioned so that it extends to the vertical through the pivot point of the polygonal roller (4).

4. The device according to item 1, characterized in that the contact point of the boom on the polygonal roller (4) below the horizontal through the center of the singling drum (5) and that the distance between the perpendicular through the centers of the singling drum (5) and the Polygonal roller (4) is smaller than the sum of the radius of the singling drum plus the inscribed circle of the polygonal roller (4).

Field of application of the invention

The invention relates to a device for aligning and feeding rod-shaped workpieces on a separating device, for example, struts for parasols. The separating device consists of a drum with longitudinal grooves and transports the workpieces continuously to subsequent processing stations.

Characteristic of the known technical solutions

According to DE-PS 1 556 693 and DE-AS 1 556 694 devices for aligning ampoules are known in which a polygonal roller with parallel to the plate plane lying polygonal cross-sections aligns the ampoules. However, the use of this arranged in the magazine polygonal roller is not suitable for aligning long heavy metal rods, as upon rotation of the polygon roller z. T. interlocked metal rods because of their large length and small diameter can bend and deform.

Object of the invention

The aim of the invention is to eliminate the deficiencies described in the prior art. It is monotonous and heavy physical work avoided and on the other hand, a high supply capacity to subsequent processing stations can be achieved.

Object of the invention

The invention has for its object to align the coming out of the magazine workpieces so that they come to rest parallel to the axis of the separating device. By preorienting the workpieces, the energy expenditure and thus the risk of deformation must be reduced.

This object is achieved in that the workpieces get out of the magazine on a rocker, which rests on a polygonal roller and is moved through it up and down, so that the workpieces are pre-positioned. As the workpieces move onto the rotating polygonal roller, they are further aligned. By rotating the polygonal roller against the feed direction of the workpieces, a single workpiece is pressed against the end face of the rocker and so finally aligned that this workpiece can slide without jamming or deformation in the longitudinal grooves of the separating roller.
