  • Device for the pressureless accumulation of loads on roller conveyors
    Patent number: 4562920
    Abstract: A friction driven live roller accumulation conveyor comprises successive load carrying sections each having at least two live rollers and a detector responsive to the presence of a load. At least one of the live rollers of each section has an associated ratchet type blocking device.The detector of each section and the immediately following section are coupled to the blocking device of each section and the blocking device of the immediately following section.The live roller associated with the blocking device in a section is blocked only when there is a load in that section and the immediately preceding section. An actuator releases the blocking device in a first or leading section to permit the advancement of loads along the conveyor.
