Abstract: A transport system and method has a support frame which carries at least a first reciprocating conveyor and a second reciprocating reference mass. The reciprocating conveyor and reference mass are connected by springs. The system has at least one first force generating apparatus and at least one activation spring connected to the force generating apparatus. The activation spring is connected to at least one reciprocating conveyor or the reciprocating reference mass. The system and method for vibration transport of goods determines the mass of goods delivered by the transport system. The support frame is carried by at least one load cell. The load cell is connected to a computer system. The computer system performs a calculation of the mass of transported goods. The computer system delivers a continuous measurement of the mass of the goods which are transported.

Abstract: The present invention concerns a drive unit for generating a reciprocating driving motion for driving movable machine elements in relation to fixed surroundings. In connection with the invention, it is relevant to speak of oscillatory motion, and in connection herewith vibrators.
