  • Patent number: 7392897
    Abstract: Vibrational linear conveyor for conveying workpieces and powdery or granular materials with a useful mass and a counter mass, which are equal in magnitude, are mounted separately at a vibrating system and, for conveying, can be brought into an opposite oscillating or vibrating movement over an electromagnetic exciter element comprising a magnet coil and a magnet armature, both of which are parts of the useful or counter mass. The workpieces or materials are transported by means of the oscillating or vibrating movement on a trough-like conveying element, which is part of the useful mass, along the conveying element, the useful and counter masses of the same magnitude lying essentially one above the other and being built up symmetrically on either side of a vertical central plane, in which the centers of mass of the useful and counter masses are resting on a common line of action.
