"Curved apron conveyor"

The invention relates to a curved apron conveyor made of hinge-like interconnected, one hinge eye on the front edge and two hinge eyes on the rear edge having metal plates with two guide surfaces running parallel to stationary guide rails.

Such a curved apron conveyor is off the German Auslegeschrift 18 13 778 and has U-shaped welded on the underside of each metal plate Metal parts. The outer surfaces of the U-shaped metal parts serve as guide surfaces, while on their bent ones Thighs are where the welds are located. These guide surfaces are located approximately in the middle between the front one Hinge eyes and the rear hinge eyes. In the practical Operation has shown with this type of apron conveyor that on the welds, especially in curve areas high bending forces act, which can lead to the breaking off of the metal parts. In addition, the manufacture of the metal plates is too precise because of the welding and straightening work Alignment of the metal parts in the longitudinal direction and with the required inclination of their guide surfaces in relation to associated with considerable effort on the underside of the metal plate.

An "improvement on the apron conveyor previously described is known from the German Auslegeschrift 19 09 712. After that, at the bottom of each metal plate is a U-shaped one Welded metal part, the two downwardly pointing legs of which rest on stationary guide rails, while the welds are on the middle connecting web. The disadvantage of this apron conveyor is that the connecting web over the underside of the Metal plate protrudes, and the sprockets thus have milled cutouts to accommodate these connecting webs have to. The arrangement of the guide surfaces in the middle area of the metal plate between the front and rear The hinge eye leads in both known apron conveyors to extremely unfavorable stress conditions and thus to a premature unilateral Wear of the guide surfaces. The reason for this is that when cornering a torque on the Metal plates act, which arise from the radial force and its distance to the plate's center of gravity and from the chain hoist is dependent.

Starting from the consideration that the one-sided wear of the guide surfaces _s can be reduced when the above torque is omitted, the invention has for its object to arrange the guide surfaces as on the underside of the metal plate, that the torque generating lever arm is as short as possible and also the The underside of the metal plates has a smooth surface. This object is achieved in that, according to the invention, in an apron conveyor of the type mentioned at the beginning, the guide surfaces are arranged on the hinge eyes of the rear edge of the metal plate. This arrangement reduces wear

of the guide surfaces, which is caused by the radial forces in the Cornering and the mentioned torque caused will. It is true that the wheel forces caused by the chain hoist cannot themselves be influenced by this, however, there is no additional torque that would cause additional stress on the guide surfaces.

Guide tabs are preferably welded to the hinge eyes and enclose them by means of an opening Hinge eyes. In this way, a simple alignment of the guide surfaces is possible and also offers that Welding with the hinge eyes no difficulties.

To raise the metal plates of the apron conveyor To prevent the stationary guide rails, the guide tabs are bent outwards at approximately right angles. The resulting tabs reach under the stationary guide surfaces.

The invention is explained in more detail below with reference to an exemplary embodiment shown in the drawing. In the drawing show:

The curved apron conveyor shown consists of metal plates 2 interlocking in a hinge-like manner. Each metal plate 2 has a 5 on its front edge Hinge eyes 4 and on the rear edge 7 two hinge eyes 6 arranged at a distance from one another. Between the hinge eyes 6 each engage a hinge eye 4 of the adjacent metal plate 2 and is through with this a hinge pin 12 is connected.

Each hinge eye 6 is welded to a guide tab 8 encompassing the hinge eye 6 = by means of the Guide tabs 8, the metal plates 2 are guided between the stationary guide rails 10. To get into the Curves a jumping out of the apron conveyor To prevent the stationary guide rails 10, each guide plate 8 has a bent at right angles, the Fixed guide rails 10 engaging under tabs 14.
