<P>PROBLEM TO BE SOLVED: To provide a package processing apparatus which improves workability in maintenance in an intermittent rotation-type rotary bagging and packaging machine, and can prevent damage and the like, for example, when a bag mouth is not properly opened or when synchronization between a gripper and the package processing apparatus is lost. <P>SOLUTION: A tuning table 49 which is driven by a drive source 48 different from a main drive source of the packaging machine is provided above a plurality of sets of grippers 3 and 3 which intermittently move on a circular orbit. The hoppers are provided in such a manner as to correspond to the respective grippers 3 and 3 along a circumferential direction of the tuning table 49. The hoppers are lifted and lowered together with the rotation of the tuning table by a cylindrical cam 63. An auxiliary cam 71 is shifted to an actuated position from a standby position on the basis of a predetermined signal, a cam roller 59 positioned below a receding position is moved to ascend or the cam roller urged to move downward through the receding position is received in a midway position, and the lowermost end of the hopper is kept in the receding position not to interfere with an uppermost end of the gripper. <P>COPYRIGHT: (C)2012,JPO&INPIT |
