Abstract:
A speed limiter for boxes or pallets for use in an a conveyor system having a tilted plane, the limiter comprising:a rotatable drum adapted to be pressed against a load, the load driving said rotatable drum;a speed-sensitive braking mechanism adapted to hinder the rotational movement of said rotatable drum;a shaft mounted coaxial to said drum, said drum and said braking mechanism being mounted about said shaft; andat least one bracket adapted to fixedly mount said shaft to a structure of the conveyor system, said bracket adapted to elastically press said drum to said load, said bracket having a predetermined degree of rotational movement such that said bracket may pivot about an axis transverse to the movement of the load, said at least one bracket comprising an elastic device providing a first level of force and a first resistance to movement of said bracket, said elastic device further providing a second level of force and a second resistance to movement of said bracket during braking of said drum, said second level of force adapted to increase the contact force between said drum and the load, said second resistance greater than said first resistance, and said at least one bracket applying said second level of force up to a predetermined threshold.
