Capper

摘要

Problem to be solved: when the cap is capped by the capping head chuck, it is accurately determined that the berries cap (mounting failure) occurs.The capping head 3 is provided with a chuck 8 for holding the cap 9 and an air gap sensor 18 for measuring the distance (distance) DX between the end face 8A on the inner side of the chuck 8 and the top surface 9b of the cap 9 opposed to the chuck 8.When it is recognized that the chuck 8 is rotationally driven by the servomotor 12 and the attachment of the cap 9 to the mouth 6C of the container 6 is completed, the determination section 23a determines if the gap amount DX measured by the gap sensor 18 is greater than a predetermined threshold D1 It is determined that a berth cap having a cap 9 attached to the mouth 6C of the container 6 is inclined (see Fig. 2b).Diagram
