Abstract
In a device that opens the mouth of each one of the bags that are suspended with the mouths facing upward and conveyed in a vertical state at a uniform speed and uniform spacing in a straight line, a pair of suction disks revolve continuously in mutually opposite directions on circular tracks on the horizontal plane so that the suction-chucking surfaces of the suction disks are always caused to face each other. The suction disks revolve at a constant speed while maintaining substantially symmetrical positions relative to each other and revolve at the same speed as the speed the bags are conveyed.
Claims7
A bag mouth opening device for continuously conveyed bags in which both sides of a mouth of each one of bags that are continuously conveyed at a uniform speed and equal intervals are suction-chucked by a pair of facing suction-chucking members, and then said suction-chucking members are separated from each other so as to open said mouth of said each one of said bags, wherein:
- said pair of suction-chucking members continuously revolve:
- in mutually opposite directions on circular tracks on a plane that is substantially parallel to a conveying direction of said bags and substantially perpendicular to surfaces of said bags, and
- in a state in which suction-chucking surfaces of said suction-chucking members are kept facing each other;
- and
- time required for said respective suction-chucking members to complete one revolution is set to be at an integral multiple of time required for said each one of said bags to be conveyed over a distance between bags.
