Filed: 1986-02-12
Abstract: PURPOSE:To align dropped containers in a predetermined direction and then to convey them into the next working station, by providing a drive mechanism which receives a detection signal from a detector and turns the containers. CONSTITUTION:When a container A is fitted in a predetermined position for a detector 12, none of proximity switches 12a-12c detect a label L, and therefore, no rotating instruction is issued to a rotary drive mechanism 7, and therefore, the condition of the container A is unaltered and is then allowed to pass through a first gate stopper 5, a container storage member 6 and a second stopper 8 so that it is finally dropped onto a discharge mechanism. When the label L is turned to the left and approaches the detecting section, the second proximity switch 12a detects it and delivers an instruction signal to the rotary drive mechanism 7 which therefore turns the container A counterclockwise by an angle of 90 deg.. Further, the first gate stopper 5 is opened to drop the container A onto the container storage member 6. Then, a motor 15 is rotated to turn a cylindrical member by means of a gear by an angle of 90 deg.. After the container A is aligned in a regular direction, the second gate stopper 8 is opened to drop the container A into a skirt section 9 to feed it into the next working station.
