Claims (1)

[Scope of utility model registration request] A rotary table that has a conveyor for moving the packaged items and that automatically stops at a predetermined position after rotating a preset number of times, and a column that is installed on a base frame independently of the rotary table. , a spiral-type stretch wrapping machine mainly consisting of a film lifting frame that moves up and down within a set stroke range along the frame,
The end of the film, which is closed and positioned above the rotary table so as to protrude from the upper surface of the rotary table, is held from below, and at a set timing after the rotation of the rotary table is started, the end portion of the film is held from below. A lower gripper is provided on the film lifting frame to open to release the film end so that it does not protrude, and after the film lifting frame stops at the upper limit of its stroke, it moves toward the center of the rotary table and closes. The unwrapped end face of the film located at is held in a pressed manner, and when the film lifting frame stops at the lower limit of its stroke, the lower gripper is made to grip the film end from below and opens to release the film end face. After that, the gripper held by the cutter arm retreats to its pre-movement position, and immediately after the film lifting frame stops at the upper limit of its stroke, it swings with a swing radius that allows it to come into contact with the side surface of the packaged object. a film presser arm holding a push bar that moves the film to a position where the film is attached to the side of the object to be packaged and the unwrapped end of the film can be gripped by the gripper held by the cutter arm; and a cutter that swings at a smaller swing radius to cut the film held by the gripper between the film holding arm and the gripper held by the cutter arm. Stretch wrapping machine.
