PURPOSE:To securely grip a container at a perpendicular attitude by providing two freely rotatable rollers and one driving roller for gripping the collar of the mouth part of the container at three positions, two roller support rods which are freely opened and closed to right and left, and a mechanism which opens and closes the support rods to right and left. CONSTITUTION:The container 3 is placed on a belt conveyor 35 and a motor is driven to move the driving roller as shown by an arrow. The roller supporting rods 52 of the container support mechanism 48 are opened to right and left to receive the container 3 and the collar 60 of the mouth part is crimped by the three rollers 49, 51, and 51 and rotated by 90 deg. as shown by an arrow together with a rotary disk 47. Then a rotary gear 53 engages a driving gear 58 and an inspection device 20 is lowered along the sensor support rods 59 to a constant position of the upper end part of the mouth part of the container 3 when the motor 56 is actuated, its force is transmitted to the driving roller 49 to which the rotary gear 53 is fixed through the driving gear 58 to rotates the container 3 and two rollers 51 and 51 with its frictional force. Thus, they are rotated while the upper part of the container 3 is supported at the three points, so the container 3 is securely held at the perpendicular attitude and the rotating operation is performed stably as well. |
