Method of producing packing body

Abstract

A method of producing a packing body includes the steps of: stacking a plurality of packaging bodies, placing reinforcing sheet materials so as to wrap outer peripheries of side surfaces of the packaging bodies that have been stacked, and fastening the packaging bodies that have been stacked by placing a fastening band from an outer side of the reinforcing sheet materials. The placing step includes placing the reinforcing sheet materials on the side surfaces of the packaging bodies to protrude an end portions of the reinforcing sheet material from an upper surface of a packaging body in an uppermost layer and from a lower surface of a packaging body in a lowermost layer. The fastening step includes bending the end portions, covering an edge portion of each packaging body, and placing the fastening band on the edge portions with the reinforcing sheet materials interposed therebetween.

1 . A method of producing a packing body comprising the steps of:
 stacking a plurality of packaging bodies, each having an upper surface, a lower surface, and side surfaces;   placing a reinforcing sheet material so as to wrap outer peripheries of the side surfaces of the packaging bodies that have been stacked; and   fastening the packaging bodies that have been stacked by placing a fastening band from an outer side of the reinforcing sheet material,   wherein the step of placing a reinforcing sheet material includes placing the reinforcing sheet material on the side surfaces of the packaging bodies such that an end portion of the reinforcing sheet material protrudes from an upper surface of a packaging body in an uppermost layer and such that an end portion of the reinforcing sheet material protrudes from a lower surface of a packaging body in a lowermost layer, and   wherein the step of fastening the packaging bodies that have been stacked includes bending the end portion of the reinforcing sheet material that protrudes from the upper surface of the packaging body in the uppermost layer and the end portion of the reinforcing sheet material that protrudes from the lower surface of the packaging body in the lowermost layer towards a side of an upper surface of the uppermost layer and towards a side of a lower surface of the lowermost layer, respectively, covering an edge portion of each packaging body, and placing the fastening band on the edge portions with the reinforcing sheet material interposed therebetween.   
     
     
         2 . The method of producing a packing body according to  claim 1 , wherein the reinforcing sheet material includes an upper reinforcing sheet material that covers the packaging body in the uppermost layer and a lower reinforcing sheet material that covers the packaging body in the lowermost layer. 
     
     
         3 . The method of producing a packing body according to  claim 1 , wherein the step of stacking a plurality of packaging bodies includes disposing side by side packaging bodies that form a small-width layer above the lowermost layer and forming a groove-shaped space that does not prevent insertion and removal of a fork of a forklift, and the step of fastening the packaging bodies that have been stacked includes placing the reinforcing sheet material at a position that does not cover the groove-shaped space. 
     
     
         4 . The method of producing a packing body according to  claim 2 , wherein the step of stacking a plurality of packaging bodies includes disposing side by side packaging bodies that form a small-width layer above the lowermost layer and forming a groove-shaped space that does not prevent insertion and removal of a fork of a forklift, and the step of fastening the packaging bodies that have been stacked includes placing the reinforcing sheet material at a position that does not cover the groove-shaped space.
