Packing method and packing apparatus

A packing method comprising the steps of carrying a substance to be packed from a carrying-in section of a packing apparatus to a position under a packing section, said carrying-in section being horizontally spaced from a position under said packing section and located at a peripheral portion of the packing apparatus;

• horizontally supplying and stretching a film at said packing section;
• positioning a carrying base under said carrying-in section, and lowering said carrying-in section in such manner that an upper surface of said carrying-in section is positioned lower than an upper surface of said carrying base, and receiving said substance to be packed from said carrying-in section to the upper surface of said carrying base;
• horizontally moving said carrying base on which said substance to be packed is placed to a position under said packing section for carrying said substance to be packed to said position under said packing section;
• vertically moving said carrying base to said packing section, and pushing-up said substance to be packed to said film at said packing section for covering an upper surface of said substance to be packed with said film;
• and
• folding the end portions of said film under a bottom portion of said substance to be packed.

A packing apparatus for carrying a substance to be packed from a carrying-in section for said substance to be packed to a position under a packing section, means for horizontally supplying and stretching a film at said packing section;

• said substance to be packed being lifted to said film for covering an upper surface of said substance to be packed with said film;
• the end portions of said film being folded under a bottom portion of said substance;
• said packing apparatus comprising;
• a carrying-in section on which said substance to be packed is placed, said carrying-in section being horizontally spaced from a position under said packing section and located at a peripheral portion of the packing apparatus;
• a carrying base being movable in horizontal and vertical directions;
• means for vertically lifting said carrying base from a position under said carrying-in section in such a manner that an upper surface of said carrying base is positioned higher than an upper surface of said carrying-in section, said substance being supplied from said carrying-in section to said carrying base;
• means for horizontally moving said carrying base on which said substance is placed to a position under said packing section for carrying said substance to be packed to said position under said packing section;
• and
• means for vertically moving said carrying base to said packing section, and pushing-up said substance to be packed to said film at said packing section.

A packing apparatus for carrying a substance to be packed from a carrying-in section to a packing section, said substance being packed with a stretched film at said packing section;

• said packing apparatus comprising:
• a packing section having folding means;
• a roll having a wound stretched film;
• film drawing means for holding the leading edge of said film and drawing said film from said roll to said packing section by a specified length;
• right and left clamping means for holding said drawn film in a stretched state at said packing section;
• a carrying-in section on which said substance to be packed is placed said carrying-in section being horizontally spaced from a position under said packing section and located at a peripheral portion of the packing apparatus;
• a carrying base being movable in horizontal and vertical directions;
• means for vertically lifting said carrying base from a position under said carrying-in section in such a manner that an upper surface of said carrying base is positioned higher than an upper surface of said carrying-in section, said substance being supplied from said carrying-in section to said carrying base;
• means for horizontally moving said carrying base on which said substance to be packed is placed to a position under said packing section for carrying said substance to be packed to said position under said packing section;
• means for vertically moving said carrying base from said packing section, and pushing-up said substance to be packed to said film at said packing section;
• and
• said folding means folding the end portions of said film under a bottom portion of said article.

A packing apparatus including a carrying base for receiving a substance to be packed from a carrying-in section by lifting movement from a lower side of said carrying-in section;

• means for horizontally carrying said substance to be packed from the carrying in section to a position under a packing section in which a film is drawn, said carrying-in section being horizontally spaced from a position under said packing section and located at a peripheral portion of said packing apparatus;
• and means for lifting and pushing-up said substance to be packed toward said film up to an area where an upper surface of said substance to be packed is covered with said film, said carrying base comprising:
• first receiving portions, each having an approximately flat upper surface, juxtaposed in one direction at specified intervals for receiving said substance to be packed;
• second receiving portions, each having an upper surface with a recessed shape being gradually inclined toward a central portion, said second receiving portions being vertically movable between said first receiving portions for receiving said substance to be packed;
• wherein the upper surfaces of said second receiving portions project higher than the upper surfaces of said first receiving portions when receiving said substance to be packed or in horizontally moving said substance to be packed;
• and the upper surfaces of said second receiving portions project lower than the upper surfaces of said first receiving portions at least when the lifting and pushing-up operation of said substance to be packed toward said film is completed.
