1. A method for packing an article, comprising:
(1) a preparing step comprising preparing an article, a pallet, a strapping machine, and at least two right-angle pad elements, wherein the article has a top surface, a bottom surface, and four side surf aces respectively arranged thereon, the top surface having a first edge and a second edge respectively arranged thereon, the article being placed on the pallet via the bottom surface of the article, the pallet having a bottom space disposed thereon, wherein the strapping machine has a plurality of movable wheels, a strap supply unit, a strap feeding and retreating control unit, a strap cutting and bonding unit, and an L-shaped strap guide unit respectively arranged thereon, wherein the plurality of movable wheels are used to move the strapping machine, wherein the strap supply unit is used to provide a packing strap, wherein the packing strap has a supply end arranged thereon, wherein the supply end is capable of being pulled out from the strap supply unit, passing through the strap feeding and retreating control unit and the strap cutting and bonding unit in sequence, and finally being set on the L-shaped strap guide unit, wherein the L-shaped strap guide unit has a strap outlet portion, a strap return portion, and a stopper portion respectively arranged thereon, wherein the supply end is disposed on the strap outlet portion;
(2) a moving step comprising moving the strapping machine by the plurality of movable wheels, and then making the strap outlet portion of the L-shaped strap guide unit extend into the bottom space;
(3) a first strap feeding step comprising controlling the strap feeding and retreating control unit to feed the packing strap so that the supply end of the packing strap extends out of the strap outlet portion;
(4) an encircling article step comprising pulling the supply end of the packing strap to wrap the packing strap around the article, then passing the supply end into the strap return portion and fixing the supply end on the stopper portion so that the packing strap surrounds the article;
(5) a first tightening step comprising controlling the strap feeding and retreating control unit to tighten the packing strap, so that the packing strap is tightly wrapped around the article;
(6) a second strap feeding step comprising controlling the strap feeding and retreating control unit to pull out a first length of the packing strap from the strap supply unit so as to generate a first insertion space between the packing strap and the first edge, and a second insertion space between the packing strap and the second edge;
(7) a manual inserting step comprising inserting the at least two right-angle pad elements into the first insertion space and the second insertion space, respectively, wherein the at least two right-angle pad elements are respectively limited by the packing strap so as to prevent the at least two right-angle pad elements from falling down;
(8) a second tightening step comprising controlling the strap feeding and retreating control unit to automatically tighten the packing strap, so that the packing strap is tightly wrapped around the article and the at least two right-angle pad elements; and
(9) a strap cutting and bonding step comprising controlling the strap cutting and bonding unit to cut off and form an overlapping portion of the packing strap adjacent to the supply end, and to bond the overlapping portion to the supply end via thermal bonding so as to complete packing of the article.
