ABSTRACT:
A wrapping machine used to wrap with a prescribed wrapper a commodity having the shape of a hexahedron having a length, a width, and a height, as well as a top surface, a bottom surface, a front surface, a rear surface, a right side surface, and a left side surface; in this wrapping machine, the commodity being wrapped in a wrapping region, this wrapping region having a central position along the length of the commodity, and a reference wrapping position along the width of the commodity; the wrapping machine further comprising: a wrapping supply device that holds at least two wrappers of different sizes, and selectively supplies either of the wrappers to the wrapping region; a sensing device, provided in the wrapper supply device, that detects the sizes of the wrappers; a control device electrically connected to the sensing device, as well as operationally connected to the wrapper supply device; this control device has a display device, and it determines whether the sizes of the wrappers are within the usable range for wrapping the commodity or not; when the sizes of two or more of the wrappers are within the usable range for wrapping the commodity, it drives the wrapper supply device to supply either of the wrappers to the wrapping region; when only one of the wrappers has the size within the usable range for wrapping the commodity, it drives the wrapper supply device to supply the usable wrapper to the wrapping region; when neither of the sizes of the wrappers is within the usable range for wrapping the commodity, it displays the size of the wrapper capable of wrapping the commodity on the display device; and a wrapper folding device provided near the vicinity of the wrapping region that wraps the commodity in the wrapping region with the wrapper supplied from the wrapper supply device.
