  • Machine for packaging flat, unsymmetrical objects
    Patent number: 4953343
    Abstract: Apparatus for feeding a preselected number of unsymmetrical objects into a package has a vibratory transporter for feeding a predetermined number of objects to be packaged into a collector and a photoelectric device for releasing the objects from the collector into a package when the predetermined number of objects are in the collector. The transporter includes a discharge trough which is slopped to one side and has a fixed siderail and a resiliently yieldable siderail which prevent jamming of unsymmetrical objects within the trough. Tracks which feed objects from an object storage unit to the trough are arranged one above the other so that the unsymmetrical objects cannot enter the trough on edge or in stacked relation to each other.
