Abstract:
A positioning system for a guide elements of a conveyor, comprising:at least one driving unit operatively coupled with the guide element and comprising a motor group and a first guide positioning element; at least one driven unit operatively coupled with the guide element and comprising a second guide positioning element; a first traction-transmitting system coupling the at least one driving unit to the at least one driven unit; the at least one driving unit, by means of the motor group, being adapted to provide a first and a second translational movement of the first guide positioning element in order to cause this first guide positioning element to move in a first direction and in a second direction, respectively, the first direction being opposite to the second direction; and the at least one driving unit, by means of the motor group, further being adapted to exert a first and a second traction force on the first traction-transmitting system in order to cause the second guide positioning element to move in said first direction and in said second direction, respectively.
