  Next, a method for manufacturing the box-connected body A having the above configuration will be described. First, the unfolded box connected body A is arranged on a horizontal plane (see FIG. 6). At that time, the box connecting body A is arranged such that the surface exposed to the outside is the lower side. For example, in the states of FIGS. 1 and 2, the surfaces exposed to the outside of the connecting plate portions 10 and 60, the outer plate portions 12 and 62, and the middle plate portions 14 and 64 are set to the lower side. In the unfolded box connected body A, a ruled line is formed in advance along a polygonal line, and each polygonal line except the polygonal line C5 is an inner surface side (an upper surface side in the arrangement state of FIG. 6). A ruled line is formed by a pressing rule pressed from above, and a broken line C5 is formed by a pressing rule pressed from the outer surface side.

  An adhesive is applied to the glue margin (second glue margin) 68 in the state where the box connector A is deployed and arranged as described above (first adhesive application step). Note that an adhesive may be applied to the connecting plate portion (first connecting plate portion) 10 (particularly, a region of the connecting plate portion 10 to which the glue margin portion 68 adheres) instead of the glue margin portion 68. That is, the adhesive is applied to the paste margin 68 or the connecting plate 10.

  Next, a region on the glue margin portion 68 side with respect to the polygonal line (first polygonal line) C3 (a region on the left side of the polygonal line C3 in FIG. 6. That is, the middle plate portion 64, the inner plate portion 66, the glue margin portion 68, and the lid portion The region consisting of 70, 72, the insertion piece portions 74, 76, and the flap portions 84, 86) is folded back to the region closer to the outer plate portion 62 than the line C3 via the line C3 (see FIG. 7). . Then, the glue margin 68 overlaps the connecting plate 10, and the glue margin 68 adheres to the connecting plate 10 (first bonding step). When the glue margin 68 is adhered to the connecting plate 10, the broken line C1 coincides with the broken line C5 (may be substantially the same).

  Next, an adhesive is applied to the glue margin portion 68, and the glue margin portion (first glue margin portion) 18 is bent with respect to the inner plate portion (first inner plate portion) 16 via the broken line C9 to form a glue. The substitute portion 18 is turned back to the upper surface side of the inner plate portion 16 (see FIG. 8). The application of the adhesive to the glue margin 68 and the folding of the glue margin 18 may not be performed at the same time, and may be performed after performing either one. When bonding the glue margin portion 68 and the glue margin portion 18, the glue margin portion 18 moves in a folded state. Therefore, it is preferable to apply an adhesive to the glue margin portion 68. Instead of applying the adhesive to 68, the adhesive may be applied to the glue margin 18 that is folded back with respect to the inner plate 16. That is, the adhesive margin portion 18 may be in a state of being folded back with respect to the inner plate portion 16 and the adhesive may be applied to either the first adhesive margin portion or the second adhesive margin portion.

The area is turned back to the area on the right side of C6 (see FIG. 12). Then, the glue margin 18 overlaps the glue margin 68, and the glue margin 18 and the glue margin 68 are adhered to each other (second bonding step).

  In the state of FIG. 12, the inner plate portion 16 overlaps the upper side of the inner plate portion 66, and thus, by opening the inner plate portion 16 with respect to the inner plate portion 66, 9, the folded state as shown in FIG. 10 (that is, the state before assembly).

  In the above description, the region on the outer plate portion 12 side from the broken line C6 is folded back along the broken line C6 from the state of FIG. 11, but the region on the connecting plate portion 10 side from the broken line C6 (see FIG. 11).

  First, the unfolded box connected body B is arranged on a horizontal plane (see FIG. 19). At this time, the box connecting body B is arranged such that the surface exposed to the outside is the lower side. For example, in the states of FIGS. 15 and 16, in the connecting plate portions 10 and 60, the outer plate portions 12 and 62, and the middle plate portions 14 and 64, the surface exposed to the outside is the lower side. In the box connection body B in the unfolded state, ruled lines are formed in advance along the broken lines, and each broken line except the broken line C5 is on the inner side (the upper side in the arrangement state of FIG. 19). A ruled line is formed by a pressing rule pressed from above, and a broken line C5 is formed by a pressing rule pressed from the outer surface side.

  An adhesive is applied to the glue margin (second glue margin) 68 in the state where the box-connected body B is deployed and arranged in this way (first adhesive application step). Note that an adhesive may be applied to the connecting plate portion (first connecting plate portion) 10 (particularly, a region of the connecting plate portion 10 to which the glue margin portion 68 adheres) instead of the glue margin portion 68. That is, the adhesive is applied to the paste margin 68 or the connecting plate 10.

  Next, the area on the glue margin portion 68 side of the polygonal line (first polygonal line) C3 (the area on the left side of the polygonal line C3 in FIG. 19) is moved to the area on the outer plate portion 62 side of the polygonal line C3 via the polygonal line C3. To a folded state (see FIG. 20). Then, the glue margin 68 overlaps the connecting plate 10, and the glue margin 68 adheres to the connecting plate 10 (first bonding step). When the glue margin 68 is adhered to the connecting plate 10, the broken line C1 coincides with the broken line C5 (may be substantially the same).

  Next, an adhesive was applied to the glue margin portion 68, and the glue margin portion 18 was bent with respect to the inner plate portion 16 via the broken line C9, and the glue margin portion 18 was folded back to the upper surface side of the inner plate portion 16. State (see FIG. 21). The application of the adhesive to the glue margin 68 and the folding of the glue margin 18 may not be performed at the same time, and may be performed after performing either one.

That is, the adhesive margin portion 18 may be in a state of being folded back with respect to the inner plate portion 16 and the adhesive may be applied to either the first adhesive margin portion or the second adhesive margin portion.

  Next, a region on the glue margin portion 18 side with respect to the polygonal line (second polygonal line) C7 (a region on the right side of the polygonal line C7 in FIG. 21. That is, the middle plate portion 14, the inner plate portion 16, the glue margin portion 18, and the lid portion). 20 and 22 and the insertion piece portions 24 and 26) are folded back to the region closer to the outer plate portion 12 than the broken line C7 through the broken line C7, so that the glue margin portion 18 and the glue margin portion are formed. 68 are bonded (second bonding step). By bonding the glue margin 18 and the glue margin 68, a box connector B in a folded state (that is, a state before assembly) is formed as shown in FIG. The above manufacturing is automatically performed by an assembling apparatus. That is, bending and bonding are performed while transporting the blanks that constitute the linked box body B in the transport direction shown in FIG.

The area on the 18 side (that is, the area composed of the middle plate portion 14, the inner plate portion 16, the glue margin portion 18, the lid portions 20, 22 and the insertion piece portions 24, 26, and the flap portions 34, 36) is connected via a broken line C7. It is in a state of being folded back with respect to a region on the side of the outer plate portion 12 from the broken line C7. Then, the glue margin 18 overlaps the connecting plate 60, and the glue margin 18 adheres to the connecting plate 60 (first bonding step). When the glue margin 18 is bonded to the connecting plate 60, the broken line C9 coincides with the broken line C5 (may be substantially the same).

  Next, an adhesive was applied to the glue margin portion 18 and the glue margin portion 68 was bent with respect to the inner plate portion 66 via the broken line C1, and the glue margin portion 68 was folded back to the upper surface side of the inner plate portion 66. State. The application of the adhesive to the glue margin 18 and the folding back of the glue margin 68 may not be performed at the same time, and may be performed after performing either one.

  Next, the area on the glue margin portion 68 side with respect to the polygonal line C3 (that is, the area composed of the middle plate portion 64, the inner plate portion 66, the glue margin portion 68, the lid portions 70 and 72, and the insertion piece portions 74 and 76) is broken. The glue margin portion 18 and the glue margin portion 68 are adhered to each other by being folded back to the region closer to the outer plate portion 62 than the broken line C3 via C3 (second bonding step). By gluing the glue margin 18 and the glue margin 68, a box connected body B 'in a folded state (that is, a state before assembly) is formed.

  In this case, the connecting plate portion 10 becomes the second connecting plate portion, the outer plate portion 12 becomes the second outer plate portion, the middle plate portion 14 becomes the second middle plate portion, and the inner plate portion 16 becomes the second inner plate portion. Portion, the glue margin portion 18 becomes a second glue margin portion, the connecting plate portion 60 becomes a first connecting plate portion, the outer plate portion 62 becomes a first outer plate portion, and the middle plate portion 64 becomes a first middle plate portion.

  As described above, by applying and folding the adhesive to the box connection bodies A and B in the unfolded state, a box connection body having two glue margins bonded can be manufactured. Since the bonding can be performed by the assembling apparatus and the manufacturing can be automatically performed by the assembling apparatus, the box connected body can be manufactured without trouble.

  In particular, in the manufacturing method of the first and second embodiments, the glue margin 18 is folded back through the broken line C7 in a folded state, or the glue margin 18 is folded back in a region closer to the glue margin 18 than the broken line C8. The glue margin 68 is already adhered to the connecting plate part 10, but the glue margin 68 is already bonded to the connecting plate part 10. Side), only the glue margin 18 needs to be provided with the function of folding back the glue margin in the assembling apparatus. Therefore, the cost of the assembling apparatus can be reduced. As a result, the box-connected body A (B) can be manufactured at low cost and without any trouble.

  On the other hand, in the case of the conventional example shown in FIG. 27, when bonding is to be performed by the assembling apparatus, the glue margin 218 is folded back from the broken line C7 with the glue margin 218 being folded, and the glue margin 218 is connected to the connecting plate part. 210, and a step of folding the glue margin 268 side from the broken line C3 with the glue margin 268 folded back to adhere the glue margin 268 to the connection plate 260, that is, On both sides of the glue margin part 218 and the glue margin part 268, a function of folding back the glue margin part is required, which increases the manufacturing cost of the assembling apparatus, and as a result, the manual bonding is not performed.
