Abstract: The current invention discloses methods and apparatus for quieter sorters. The quieter sorter reduces the collision noises generated by movable pins of the sorter trays and a Geneva wheel which controls the movement of the sorter trays. The movable pins generally receive a force, and the force is necessary to advance the trays in a predetermined direction. As a particular pin approaches the Geneva wheel, a collision protector isolates this approaching movable pin from the force. When the Geneva wheel engages the isolated movable pin, since the isolated pin is free from the force, the isolated pin does not collide onto the Geneva wheel. This smooth engagement of the Geneva wheel substantially reduces the noise level associated with the travel of the movable pins.
