1. A conveyance device that conveys articles, the conveyance device comprising:
a circulation path; and
movable modules that are movable on the circulation path, wherein
the movable modules include a group of a first movable module provided with a main container, a second movable module positioned before the first movable module in a movement direction on the circulation path, and a third movable module positioned after the first movable module in the movement direction, the group movable together on the circulation path,
the second movable module and the third movable module are each provided with a guide container able to hold a respective side of an article placed on the main container, the guide container of the second movable module supporting the article from the front in the movement direction, and the guide container of the third movable module supporting the article from the rear in the movement direction,
the article is conveyable by the group of the movable modules as a conveyance unit,
the article is a packing box having a box portion and a lid portion extending from an open edge of the box portion,
the conveyance device further comprises a sealer that when the packing box has been filled with a product and conveyed on the circulation path, seals the packing box by closing the lid portion of the packing box, bending flaps of the lid portion, and adhering the box portion to the flaps of the lid portion, and
after the sealing, while the first movable module is moving in a straight line on the circulation path, the guide containers provided to the second movable module and the third movable module press against front and rear flaps of the lid portion of the packing box from the front and rear, respectively, and conduct pressure-fixing, fixing the flaps to the box portion.
2. A conveyance device that conveys articles, the conveyance device comprising:
a circulation path; and
movable modules that are movable on the circulation path, wherein
the movable modules include a group of a first movable module provided with a main container, a second movable module positioned before the first movable module in a movement direction on the circulation path and a third movable module positioned after the first movable module in the movement direction, the group movable together on the circulation path,
the second movable module and the third movable module are each provided with a guide container able to hold a respective side of an article placed on the main container, the guide container of the second movable module supporting the article from the front in the movement direction, and the guide container of the third movable module supporting the article from the rear in the movement direction,
the article is conveyable by the group of the movable modules as a conveyance unit,
when the second movable module moves on a first curve on the circulation path, a first distance between the second movable module and the first movable module is greater than that when moving in a first straight line on the circulation path, and
when the third movable module moves on a second curve on the circulation path, a second distance between the third movable module and the first movable module is greater than that when moving in a second straight line on the circulation path.
3. The conveyance device of claim 1 , wherein
the packing box is semi-finished, and
the conveyance device further comprises a box maker that forms the semi-finished packing box by bending portions of a packing member in the form of a sheet that are to be ridge lines, and transfers the semi-finished packing box onto the main container.
