A package container tube processing apparatus by which a vertical tube (W) filled with contents is divided into lengths each corresponding to one container to form intermediate containers. The apparatus comprises an upwardly and downwardly movable frame (2),a pair of pressure arms (5,6) supported at their lowest portions by the movable frame (2) and a pair of seal bars (3,4) fixed to the upper portions of the pressure arms (5,6) respectively and opposed to each other. The two pressure arms (5,6) are pivotable between a closed position where the two seal bars (3,4) are close to each other and an open position where the two seal bars (3,4) are away from each other. A stationary engaging member (63) having an upwardly open engaging recess (62) has been provided on one of the pressure arms (6) so as to project into a space between the two pressure arms (5,6). A movable engaging member (64) having a downward engaging projection (65) engageable in the recess (62) and a hydraulic cilinder (66) having the movable engaging member (64) attached to its piston rod (67), has been mounted on the other pressure arm (5). The hydraulic cilinder is rotatable about an axis parallel to the center of pivotal movement of said other pressure arm (5),and a work lever (75) having a downward arm (78) and an upward arm (80) is supported by said other pressure arm (5) concentrically with the center of rotation of the hydraulic cilinder. A pusher member (82) is fixed to said one pressure arm (6) to push the work lever (75) in the same direction as the direction of pivotal movement of said other pressure arm (5) upon coming into contact with the free end of the downward arm (78) in the late stage of pivotal movement of the two pressure arms (5,6) from the open position toward the closed position. Further there are means for transmitting to the hydraulic cilinder (66) the rotation of the work lever (75) pushed by the pusher member (82). |
