Abstract:
A product transfer assembly includes separate transfer segments mounted in a vending machine such that they are disposed in spaced relationship above one another. Each transfer segment has a ramp of helical shape with an exit end and an entrance end spaced above the exit end such that the ramps of the transfer segments together define a path of travel taken by a product item down and in contact with the ramps which includes spaced apart portions helical in shape and reversing the direction of travel of the product item, relative to a generally vertical reference axis, going from one portion to the next portion of the path. Entrance and exit ends of each ramp are angularly displaced from corresponding ends of an adjacent ramp such that the object free-falls out of contact with any ramp between the exit and entrances ends of adjacent ramps.
