Description

Die Figuren 1 und 2 zeigen die Beschickungseinrichtung für Profilmaterial zum Rollgang 1 der Profilstrahlanlage. Die Beschickungseinrichtung ist rechtwinklig zum Rollgang 1 angeordnet und ragt in diesen hinein. Hauptbestandteile sind die beiden Ausleger 2, angeordnet auf einer gemeinsamen Welle 3. Die Ausleger 2 sind als stabile Gitterkonstruktion ausgeführt. Antriebsseitig sind Kettenräder 4 mit der Lagerung 5 vorgesehen und sind formschlüssig zum Transport der Kette 6 mit der gemeinsamen Welle 3 verbunden. Die Kette 6 ist mit Platten 7 bestückt, die so dimensioniert sind, daß sie sich während des Kettenlaufs gleitend auf dem oberen Langträger 8 abstützen. Die konstruktive Auslegung der Lagerung 5 ermöglicht eine Schwenkbewegung des Auslegers 2 und den gleichzeitigen Antrieb der Kettenräder 4. Abtriebsseitig sind die Kettenräder 9 so gelagert, daß über Stehbolzen 10 ein Nachspannen der Kette 6 möglich ist. Gleichzeitig dient die Achse 11 als Gelenkpunkt für die Stütze. 12. Beide Stützen 12 werden durch einen auf einer gemeinsamen Welle 13 sitzenden Hebelmechanismus 14, der eine Kräfteübersetzung von 1:3 realisiert, angelenkt und ermöglicht so durch das Heben und Senken der Ausleger 2. Antriebsseitig wird die Welle 3 durch einen Elektromotor 17, der an einer der beiden Lagerstützen 16 befestigt ist, angetrieben. Die elektrische Schaltung für die Beschickungseinrichtung ist so ausgelegt, daß die Belegung der Ausleger 2 mit Profilmaterial schrittweise erfolgt, d.h., eine bestimmte Anzahl von Profilen 18 wird in definiertem Abstand zueinander zum Rollgang 1 transportiert und hier durch Senken der Ausleger 2 abgelegt.Figures 1 and 2 show the feeding device for profile material for roller table 1 of the profile beam system. The loading device is arranged at right angles to the roller table 1 and projects into it. Main components are the two arms 2, arranged on a common shaft 3. The boom 2 are designed as a stable grid construction. Drive side sprockets 4 are provided with the bearing 5 and are positively connected to transport the chain 6 with the common shaft 3. The chain 6 is equipped with plates 7, which are dimensioned so that they are supported during the chain running sliding on the upper longitudinal beam 8. The structural design of the bearing 5 allows a pivoting movement of the boom 2 and the simultaneous drive of the sprockets 4. On the output side, the sprockets 9 are mounted so that over stud bolts 10, a retightening of the chain 6 is possible. At the same time the axis 11 serves as a hinge point for the support. 12. Both supports 12 are articulated by a seated on a common shaft 13 lever mechanism 14, which implements a power ratio of 1: 3, and thus allows by raising and lowering the boom 2. On the drive side, the shaft 3 by an electric motor 17, the is attached to one of the two bearing supports 16, driven. The electric circuit for the charging device is designed so that the occupancy of the boom 2 with profile material takes place stepwise, that is, a certain number of profiles 18 is transported at a defined distance from each other to the roller table 1 and stored here by lowering the boom 2.

Die Vorteile der erfindungsgemäßen Lösung bestehen darin, daß bedingt durch den konstruktiven Aufbau ein automatischer Beschickungsvorgang durchführbar ist, alle Bauteile verschleißarm sind, die Wartung keinen großen Zeitaufwand erfordert und alle Anforderungen des Arbeitsschutzes eingehalten werden.The advantages of the invention are that due to the structural design of an automatic loading process is feasible, all components are wear, maintenance does not require much time and all requirements of occupational safety are met.

Field of application of the invention

The invention relates to a loading device that conveys profile material to the roller table of a profile blasting machine, wherein the loading device is arranged at right angles to the roller table.

Characteristic of the known technical solutions

It is a feeding device for a bar-shaped material processing automatic sawing machine with a trained for receiving a supply of rod-shaped material as a magazine loader and at least one arranged between this and the sawing machine cross conveyor and an acting together with this separating device and one of these separating device, submitted individual profiles to the saw advancing roller conveyor, wherein the supply of the rods to the transverse conveyor takes place via an inclined plane. By means of a lock a profile bar is released and transported by a conveyor belt to the roller conveyor. The solution according to the invention utilizes the circular cross-section of the rods for autonomous transport of the same to the transverse transport device by means of inclined plane in the processing of the storage container. It is suitable from the principle arch for box-shaped cross-sections, but this again presupposes the presence of an already positioned layer of profile bars on the inclined plane.

Object of the invention

The object of the invention is to provide a loading device that allows a certain number of profiles stored at a defined distance from each other on the feeder and this lot is completely transported to the roller table.

Explanation of the essence of the invention

The invention has for its object to make the device constructive so that two outriggers in the form of plate belt conveyors, which protrude into the roller table, bring about the loading process. According to the invention the object is achieved in that arranged on a common shaft and designed as a stable grid construction boom are provided, the drive side sprockets with the bearing are provided, which are positively connected for transporting the chain with the common shaft and driven side sprockets are provided and with an axis and two supports which are articulated by a seated on a common shaft lever mechanism in operative connection. The function of the solution according to the invention is that the loading device is arranged at right angles to the roller table. Main components of the feeder are two outriggers, in the form of plate belt conveyors, which protrude into the roller table. Both booms are connected on the drive side by a common shaft and mounted rotatably on this. The entire unit is arranged to the roller table, that the boom in a horizontal position by a certain ftetrag above the upper edge of the roller table rollers stc-i.on. On the drive side, the height level is determined by bearing supports. On the output side, both arms are supported on a pneumatically tilted lever mechanism connected by a common shaft.

The stroke of the cylinder and the corresponding lever ratio determine the amount of upward and downward movement of the oyster. The proposed design principle allows to occupy the boom in a horizontal position step by step with profile material to transport the launched lot to the roller table and to pass the profile to the current roller table after stopping by lowering the boom. The loading of the boom in a lowered state is also possible. Here, however, must be raised again before transport to the roller table before the lowering process takes place again.

embodiment

The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawings show FIG. 1: front view of the feed - roller table profile blast machine,
