A frame member, a plurality of supply product receiving arms provided on the frame member via arms, an abutting plate that comes into contact with the tip of the transported object and stops, and an arm that can be moved up and down by the arm. And a U-shaped mold forming member that surrounds the supply receiving arm, and when the supply receiving arm is raised by the strut, the mold forming member is also integrally lifted by the arm and expanded upward. Press wrapping film Lower, which is constituted of supplies cradle device in the packaging machine, characterized in that only the later-shape forming member is lowered.

As a second device including the first device, each supply item receiving arm constitutes a supply item receiving device in a packaging machine in which an upper end of the supply item receiving arm is bendable.

As a second invention including the first invention, the abutting plate constitutes a supply receiving device in a packaging machine in which a side in contact with the transported object is inclined.

[0009]

[Action]

 This invention adopts the above means. First, when the sandwich is placed on the supply transport section, the sandwich is transported by the supply transport section and further transported by the transport belt of the supply cradle unit. , Reach the top surface of the plurality of supply receiving arms. In this case, the tip of the sandwich comes into contact with the abutting plate and stops on the upper surface of the supply receiving arm.

After that, the sandwich is lifted up by the pillars, and first, the U-shaped mold forming member pushes up the central portion of the packaging film that has been previously conveyed and developed, and is located on the upper surface of the supply receiving arm. As a result of the rise of the sandwich, the sandwich will not be subjected to a large force from the packaging film. Then, after the upper surface and the side surface are covered with the packaging film, only the U-shaped mold forming member descends below the blade member that wraps the lower surface. It will wrap the underside. After that, the push-out pusher is activated to send the sandwich covered with the packaging film to the upper surface of the conveyor, and thus is discharged by this conveyor.
