Supply device with an eccentric vibrating cylindrical container for the supply of products to be packaged particularly by machines for blister packaging

A supply device with a vibrating cylindrical container for the supply of products to be packaged, particularly designed for blister packaging machines, to the vibrating cylindrical container communicating with a device with multiple supply channels, characterised in that the vibrating cylindrical container has a vertical axis which is eccentric with respect to the vertical axis of the vibrator unit which supports it and has an annular base developing in a helically ascending manner from a first straight line at which point the vibrating cylindrical container communicates with the said device with multiple supply channels, followed by a portion below said annular base leading to said device with multiple supply channels, and in that respective flow stop and guide means are provided along said base with an ascending development for guiding products in multiple rows and guide means are provided along said portion for said multiple row products supply and suction means respectively for supplying the product to be packaged to the peripheral zone of the container in which the said flow stop means are located and to suction the dust and/or fragments of product below the base of the container at the opposite sides of the device with multiple supply channels.
