Weigher apparatus for measuring can type works or the like in standing posture on product line

A weigher apparatus comprising:

• rotating/conveying means for sequentially receiving can-like objects to be weighed and for conveying the can-like objects along an arcuate path, said rotating/conveying means including:
• a rotating/conveying circular plate rotated at a predetermined speed, and having a plurality of notched portions formed in an outer peripheral portion thereof, said notched portions being spaced from each other at a predetermined interval and each said notched portion having a diameter larger than a diameter of each of the can-like objects,
• an outer guiding member provided along said outer peripheral portion of said rotating/conveying circular plate, and having a diameter larger than an outer diameter of said rotating/conveying circular plate, and
• an inner guiding member provided along said outer peripheral portion of rotating/conveying circular plate, and having a diameter smaller than the outer diameter of said rotating/conveying circular plate;
• said arcuate path being defined by said inner and outer guiding members, said outer and inner guiding members respectively having stepped portions at an intermediate portion of said arcuate path;
• the can-like objects being sequentially engaged with inlet portions of said notched portions, and conveyed along said arcuate path, and when the can-like objects reach said intermediate portion having said stepped portions of said outer and inner guiding members, the can-like objects enter the respective notched portions, and are set in a free state out of contact with inner surfaces of the respective notched portions;
• straight conveying means for conveying in a substantially straight line the can-like objects which are set in a free state at said intermediate portion of said arcuate path;
• and
• weighing means for weighing the can-like objects which are being conveyed in the substantially straight line by said straight conveying means, with the can-like objects again being engaged with said inlet portions of said notched portions and conveyed along said arcuate path after passing through said intermediate portion and being weighed.
