Abstract
A method of packing rearms of sheets, wherein each ream is defined by sheets stacked to form a rectangular-base prism of a given height, and has two base faces defined by respective end sheets in the ream, two lateral faces perpendicular to the base faces, and two end faces. The method providing for feeding the ream along a given path in a feed direction parallel to the base faces. Placing a sheet of packing material along the path of the ream and perpendicular to the feed direction, and conveying the ream and the sheet of packing material in the feed direction through a folding spindle to fold the sheet of packing material into a U about the ream.
Claims21
A method of packing reams of sheets, wherein each ream is defined by sheets stacked to form a rectangular-base prism of a given height, and comprises two base faces defined by respective end sheets in said ream, two lateral faces perpendicular to the base faces, and two end faces;
- the method comprising feeding said ream along a given path by means of a feed unit, comprising a first conveyor pushing said ream in a feed direction parallel to said base faces, placing a sheet of packing material along the path of the ream by means of a supply unit for supplying sheets of packing material, placing said sheet of packing material crosswise to said feed direction, conveying the ream and the sheet of packing material through a folding spindle to form a U-shaped fold;
- conveying said ream and said partly folded sheet of packing material by means of adjacent second, third and fourth conveyors, wherein said third conveyor is located between said second and fourth conveyors and includes two belt conveyors to grip the ream and the sheet of packing material between said belt conveyors, and turning over said third conveyor (15), together with the ream and the partly folded sheet of packing material, about an axis perpendicular to said feed direction to fold a portion of the sheet of packing material into an L.
A machine for packing reams of sheets, wherein each ream is defined by sheets stacked to form a rectangular-base prism of a given height, and comprises two base faces defined by respective end sheets in said ream, two lateral faces perpendicular to the base faces, and two end faces;
- the machine comprising a feed unit for feeding said ream along a given path, a supply unit for supplying sheets of packing material and for placing a sheet of packing material along the path of the ream, a folding spindle located along the path to fold the sheet of packing material into a U about said ream;
- wherein said feed unit comprises a first conveyor for pushing said ream, at said folding spindle, in a feed direction parallel to said base faces;
- wherein said supply unit comprises a conveying device for keeping said sheet of packing material crosswise to the feed direction at said folding spindle, wherein said feed unit comprises adjacent second, third and fourth conveyors for feeding said ream and said partly folded sheet of packing material along said path in said feed direction;
- wherein said third conveyor has a drum supporting two belt conveyors parallel to and facing each other to grip the ream and the sheet of packing material;
- said drum rotating about an axis perpendicular to said feed direction to fold a portion of the U-folded sheet of packing material into an L about the ream by means of fixed folding members.
A method of packing products comprising feeding at least one product along a given path and in a given direction by means of a feed unit, comprising a first conveyor placing a sheet of packing material along said path by means of a supply unit for supplying sheets of packing material, placing said sheet of packing material crosswise to said feed direction, conveying the product and the sheet of packing material through a folding spindle to form a U-shaped fold;
- conveying said product and said partly folded sheet of packing material by means of adjacent second, third and fourth conveyors, wherein said conveyors comprise a third conveyor is located between said second and fourth conveyors and includes two belt conveyors to grip the product and the sheet of packing material between said belt conveyors, and turning over said third conveyor, together with the product and the partly folded sheet of packing material, about an axis perpendicular to said feed direction to fold a portion of the sheet of packing material into an L.
A machine for packing products comprising a feed unit for feeding at least one product along a given path, a supply unit for supplying sheets of packing material and for placing a sheet of packing material along the path of the product, a folding spindle located along the path to fold the sheet of packing material into a U about said product, wherein said feed unit comprises a first conveyor for pushing said product, at said folding spindle, in a feed direction parallel to said base faces;
- wherein said supply unit comprises a conveying device for keeping said sheet of packing material crosswise to the feed direction at said folding spindle, wherein said feed unit comprises adjacent second, third and fourth conveyors for feeding said product and said partly folded sheet of packing material along said path in said feed direction;
- wherein said third conveyor has a drum supporting two belt conveyors parallel to and facing each other to grip the product and the sheet of packing material;
- said drum rotating about an axis perpendicular to said feed direction to fold a portion of the U-folded sheet of packing material into an L about the product by means of fixed folding members.
