Description

  The present invention relates to a packaging box and a packaging method that enable simple assembly and unpacking.

  It is a packing box made of wooden boxes that is necessary for packing and transporting materials such as machinery and equipment that are relatively heavy and difficult in strength with corrugated cardboard packaging and require special fixation. Since the packaging box is damaged at the time of dismantling and it is difficult to reuse it, a reusable packaging box technology is required. For example, a packing box 120 using the spring joint 101 is shown in FIG. 7, and a groove processing portion formed at a corner of the packing box 120 has a spring on the frame member 111 as shown in FIG. A groove 102 to which the central body 101a of the joint 101 is attached and a groove 103 to which the arm 101c is attached are formed. Only the groove 104 in which the arm portion 101c is mounted is formed in the skeleton member 112. Then, one spring joint 101 fastens the frame members 111 and 112, another spring joint 101 fastens the frame members 113 and 114, and another spring joint 101 fastens the frame members 115 and 116. Yes. As described above, the horizontal plates 122 and 123 are mounted on the base plate 121, and the top plate 124 is put on and fixed by the plurality of spring joints 101. Conversely, when the packaging box 120 is disassembled, as shown in FIG. 7B, the members are not damaged because the disassembly is performed while removing the spring joint 101 using a hand or a jig (Patent Document 1). .

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  A lower waist 2 disposed on the bottom side of the packaging box 1 according to the present invention is shown in FIG. The lower back 2 is formed by combining a plurality of square bars as shown in FIG. In the basic configuration, the skid 21 and the load material 22 are mainly formed. In the lower waist 2 in this example, the three skids 21 are arranged in parallel to each other at equal intervals, and the headers 23 are arranged on both ends 211 side in the longitudinal direction of the skids 21 arranged at equal intervals. It is arranged in a direction that crosses (crosses) the direction. As shown in FIG. 1A, the header 23 covers all the two end portions 211 in the longitudinal direction of the three skids 21 in a direction crossing (crossing) the longitudinal direction of the skid 21. That is, the length of the header 23 in the longitudinal direction arranged on the skid 21 is the same as the length in the direction crossing (intersecting) the longitudinal direction of the three skids 21 arranged in parallel at equal intervals. Yes. Therefore, as shown in FIG. 1, the skid 21 does not protrude from the header 23, and the skid 21 does not protrude from the header 23.

  Between the headers 23, 23 arranged on both ends 211 in the longitudinal direction of the three skids 21, the load material 22 is arranged in a direction crossing the longitudinal direction of the three skids 21. The load member 22 basically has the same shape as the header 23, and is disposed on the skid 21 in the same state as the header 23 is disposed on the skid 21. In this example, four load members 22 are used and are arranged in parallel to each other in a direction crossing the longitudinal direction of the three skids 21. The number and arrangement of the load materials are arbitrarily set according to the shape and size of the packaged product 8.

  In this example, the load member 22 including the header 23 is arranged at a position that is symmetric about the direction crossing (intersecting) the center of the longitudinal direction of the three skids 21. The above is the configuration of one skid surface 212 of the three skids 21. On the other hand, on the other skid surface 213 of the three skids 21, as shown in FIG. 1B, a rootstock 24 is arranged in a direction crossing the longitudinal direction of the three skids 21. . In this example, the rootstocks 24 are arranged at a total of three locations on the side crossing the longitudinal center of the three skids 21 and on both end portions 211 side in the longitudinal direction of the three skids 21. Of these, the rootstocks 24, 24 arranged on the two end portions 211 side in the longitudinal direction of the three skids 21 extend beyond the skid 21 by the thickness of the rootstock 24. ing. That is, the protruding portions 241 and 241 of the rootstocks 24 and 24 projecting in the direction crossing the longitudinal direction of the three skids 21 are formed on both ends 211 and 211 in the longitudinal direction of the three skids 21. . In this way, by forming the protruding portion 241, the upper load of the packaging box 1 can be directly transmitted to the grounding surface of the rootstock 24. On the other hand, the rootstock 24 arranged in the direction crossing the longitudinal center of the three skids 21 has the same length in the direction traversing the longitudinal center of the three skids 21. The rootstock 24 does not extend beyond the skid 21.

  Next, of the three skids 21, two engaging portions 25 are formed on the side surface portions 214 of the two outer skids 21. As shown in FIG. 1A, the engaging portion 25 is a hole formed adjacent to the outer skids 21 and 21 and extending in the thickness direction of the skid 21. The engaging portion 25 includes a spacer 251 and a batten 252. Specifically, the spacers 251 and 251 are opposed to each other, arranged on the side surface portion 214 of the outer skid 21 with a space therebetween, and the batten 252 is arranged on the spacers 251 and 251, thereby A gap formed between the batten 252 and the batten 252 is configured as an engaging portion 25. In this example, the engaging portions 25 are arranged at two positions that are symmetric with respect to the direction crossing the longitudinal center of the three skids 21. Further, the engaging portion 26 is disposed on the side surface portion 242 of the rootstock 24 disposed on the both end portions 211 side in the longitudinal direction of the three skids 21, which is the heel surface direction of the lower waist 2. The engagement portion 26 in the heel surface direction of the lower waist 2 is the same as the engagement portion 25 of the side surface portion 214 of the two outer skids 21, the spacers 261 and 261 are opposed to each other, and the outer side is spaced apart. A gap formed between the spacers 261 and 261 and the batten 262 by arranging the batten 262 on the side surface 242 of the rootstock 24 is configured as the engaging part 25.

  The above is the configuration of the lower back 2 in this example, but is not particularly limited to this form, and the number of skids 21, load materials 22 and the like are appropriately changed according to the size and shape of what is to be packed. Will be used. Next, the side surface 3 that is inserted into (engaged with) the engaging portion 25 of the lower waist 2 will be described.

  The side surface 3 is formed by combining a plurality of square members as shown in FIG. In the basic configuration, it is mainly formed by the side rail 31 and the side plate 32. In the side surface 3 in this example, the three side bars 31 are arranged in parallel with each other at equal intervals, and the side plate 32 extends in a direction crossing (crossing) the longitudinal direction of the side bars 31 arranged at equal intervals. They are arranged parallel to each other. Two of the side plates 32 are arranged on both ends 311 side in the longitudinal direction of the three side rails 31 in a direction crossing (intersecting) the longitudinal direction of the side rails 31 as shown in FIG. Has been. In the arrangement of the side plates 32 on the two side rails 31, one end portion 321 of the side plate 32 coincides with the upper surface portion of the side rail 31 on the one end portion 321 side of the side plate 32. That is, as shown in FIG. 2A, the side plate 32 does not protrude from the side rail 31, and the side plate 32 does not protrude from the side rail 31. However, both end portions 311 and 311 in the longitudinal direction of the three side bars 31 extend beyond the side plates 32 and 32 (extruded).

  In other words, on both ends 311 and 311 in the longitudinal direction of the three side bars 31, along the longitudinal direction of the three side bars 31 protruding in a direction crossing (intersecting) the two longitudinal directions of the side plates 32. The protruding portions 312 and 312 are formed. In the gaps 313 and 313 between the protruding portions 312 and 312 on the one end 321 side of the side plate 32, a reinforcing vertical beam 33 and a rod sandwiching beam 34 are incorporated. The reinforcing vertical beam 33 is a plate-shaped member, and has the same thickness as the side beam 31, and the rod sandwiching beam 34 is a member having a shape close to a bar-shaped member having a square cross section. It is thick. In addition, the length in the longitudinal direction of the reinforcing vertical beam 33 and the length in the longitudinal direction of the rod sandwiching beam 34 are the same (same).

  When assembling into the gaps 313 and 313 between the protruding portions 312 and 312, the reinforcing vertical beam 33 is locked to the side plate 32 in the vicinity, and the protruding portions on the side ends 311, 311 side in the longitudinal direction of the side beam 31 The reinforcing vertical bars 33 are housed in 312 and 312, and as shown in FIG. 2A, the end surface 331 of the reinforcing vertical bar 33 is made to coincide with the end surface 312 a of the protruding portion 312. On the reinforcing vertical bar 33, the rod sandwiching bar 34 is arranged, and the end surface 341 of the rod sandwiching bar 34 is arranged to coincide with the end surface 331 of the reinforcing vertical beam 33. In other words, the bar clamping bar 34 is arranged in parallel with the reinforcing vertical bar 33. As a result, as shown in FIG. 2, a gap 314 is formed on the reinforcing vertical beam 33 between the side plate 32 and the eaves sandwiching beam 34. Further, as shown in FIG. 2B, there is nothing in the direction along the longitudinal direction of the rod clamping bar 34 (there are no protruding portions 312, 312), and the reinforcing vertical beam 33. In the above state, the sword sandwiching bar 34 protrudes.

  In addition, in this example, it is set as the vertical beam 33 for reinforcement | strengthening and the crosspiece 34 for the cage | baskets of the length which can form the space | gap 313a where the band 5 passes previously.

  Moreover, in this example, as shown in FIG. 2A, four side plates 32 are used, and the two side plates 32 arranged on both ends 211 side in the longitudinal direction of the three side bars 31 are excluded. The remaining two side plates 32 are arranged on the three side bars 31 at intervals from the two arranged on the both ends 211 side in the longitudinal direction of the three side bars 31. In this example, as shown in FIG. 2A, the side plate 32 is disposed at a position that is symmetric with respect to a direction crossing the center in the longitudinal direction of the side rail 31. At the other end 322 of the side plate 32, the side plate 32 extends beyond the side bar 31 (extends) in the direction transverse to the longitudinal direction of the three side bars 31. That is, among the three side bars 31, the side bars 31 extend beyond the side bars 31 on the other end 322 side of the side plate 32. On the other end 322 side of the side plate 32, a squeezed portion 323 is formed which is a protruding portion of the side plate 32 protruding in the longitudinal direction of the three side bars 31. Since the ridge portion 323 is incorporated in the engaging portion 25 of the lower waist 2, the length, thickness, etc. of the ridge portion 323 are large corresponding to the engaging portion 25 of the lower waist 2. .

  The above is the configuration of the side surface 3 in this example. However, the number of side bars 31, side plates 32, and the like are appropriately changed according to the size and shape of what is packed without being limited to this form. Will be used. Next, the collar surface 4 that is inserted into (engaged with) the engaging portion 26 of the lower waist 2 will be described.

  As shown in FIG. 3A, the collar surface 4 is formed by combining a plurality of plate-like members in the same manner as the lower waist 2 and the side surface 3. Basically, it is made up of a crosspiece 41 and a side plate 42. In the ridge surface 4 in this example, three ridge bars 41 are arranged in parallel to each other at equal intervals. Further, in this example, three hook plates 42 are arranged in parallel to each other at equal intervals in a direction crossing (intersecting) the longitudinal direction of the bridge bar 41. In the arrangement of the bridge plate 42 on the bridge plate 41, the bridge plate 41 arranged on one end 421 side of the plate 42 crosses the longitudinal direction of the frame plate 41 as shown in FIG. It covers all the ends 421 in the longitudinal direction of the three ribs 42 in the direction of crossing. That is, the length of the crosspiece 41 in the longitudinal direction where the crossbar 42 is arranged is the same as the length in the direction crossing (crossing) the longitudinal direction of the three crossplates 42 arranged in parallel at equal intervals. It has become. Therefore, as shown in FIG. 3, the eaves frame 41 does not protrude from the eaves plate 42, and the eaves frame 41 does not protrude from the eaves plate 42.

  On the other end 422 side of the saddle plate 42, the saddle plate 42 extends beyond the saddle rail 41 in a direction transverse to the longitudinal direction of the three saddle rails 41. That is, among the three ridge bars 41, they extend beyond the ridge bar 41 on the other end 422 side of the ridge plate 42 (extends). That is, as shown in FIG. 3 (b), on the other end 422 side of the saddle plate 42, it is a protrusion that is a protruding portion of the saddle plate 42 protruding in the longitudinal direction of the three cross rails 41. A portion 423 is formed. Since the ridge portion 423 is incorporated in the engagement portion 26 of the lower waist 2, the length, thickness, etc. of the ridge portion 423 are large corresponding to the engagement portion 26 of the lower waist 2. .

  The above is the configuration of the ridge surface 4 in this example, but is not particularly limited to this form, and the number of the ridge frames 41, the ridge plates 42, etc. are appropriately determined according to the size and shape of what is packed. It will be changed and used. When assembling the side surface 3 and the heel plate 4 to the lower waist 2, the two side surfaces 3 are assembled to the lower waist 2, and the two heel surfaces 4 are assembled to the lower waist 4. In addition, the two side surfaces 3 and 3 facing each other with respect to the lower waist side 2 are in a state in which the side plates 32 are opposed to each other, and the two opposing collar surfaces 4 and 4 are in a state in which the collar plates 42 are opposed to each other. Then, assembly will be performed. Below, the assembly of the side surface 3 and the saddle plate 4 to the lower waist 2 will be described.

  When assembling the side surface 3 and the heel plate 4 to the lower waist 2, the side surface 3 can be incorporated into the lower waist 2 first, or the heel surface 4 can be incorporated into the lower waist 2 first. Furthermore, it is possible to incorporate the side surface 3 and the heel surface 4 into the lower waist 2 at the same time. The side surface 3 and the heel surface 4 are incorporated into the lower waist 2 by any method. Specifically, the side surface 3 is arranged so as to be assembled with the lower waist 2 (for example, the side surface 3 is perpendicular to the lower waist 2), and the engaging portions 25, 25 of the lower waist 2 are arranged. The nipping parts (protruding parts) 323 and 323 of the side surface 3 are arranged to face each other. Similarly, it arrange | positions so that the collar surface 4 can be assembled with respect to the lower back 2 (for example, the vertical surface 4 is made perpendicular | vertical with respect to the lower waist 2), and with respect to the engaging parts 26 and 26 of the lower waist 2 The indented portions (protruding portions) 423 and 423 of the collar surface 4 are arranged to face each other.

  Next, the side surface 3 and the heel surface 4 arranged to face the lower waist 2 are respectively moved to the lower waist 2 side. That is, the insertion portions 323 and 323 of the side surface 3 are inserted into the engaging portions 25 and 25 of the lower waist 2, and the side surface 3 extends along the plate thickness direction of the lower waist 2 (in the direction of arrow A shown in FIG. 1B). Move along). Similarly, the insertion portions 423 and 423 of the collar surface 4 are inserted into the engaging portions 26 and 26 of the lower waist 2, and the collar surface 4 extends along the thickness direction of the lower waist 2 (the arrow shown in FIG. 1B). Move along direction A). The moving side surface 3 contacts the lower waist 2. The movement of the side surface 3 with respect to the lower waist 2 is completed when the side rail 31 on the other end 322 side of the side surface 3 contacts the spacers 251 and 251 of the lower waist 2. By the completion of the movement, the grip portions 323 and 323 of the side surface 3 enter the engaging portions 25 and 25 of the lower waist 2, and the incorporation of the side surface 3 into the lower waist 2 is completed. Similarly, the moving heel surface 4 contacts the lower waist 2. The movement of the heel surface 4 with respect to the lower waist 2 is completed by the heel bar 41 on the other end 422 side of the heel surface 4 coming into contact with the spacers 261 and 261 of the lower waist 2. By the completion of the movement, the inserting portions 423 and 423 of the collar surface 4 enter the engaging portions 26 and 26 of the lower waist 2, and the incorporation of the collar surface 4 into the lower waist 2 is completed. At that time, the ridge portion 323 of the side surface 3 and the ridge portion 423 of the heel surface 4 that do not oppose the engagement portions 25, 25 of the lumbar surface 2 are similarly in the plate thickness direction of the lower waist 2 (arrow A direction). Move along. When the movement of the side surface 3 with respect to the lower waist 2 is completed, the pinched portion 323 of the side surface 3 enters between the protruding portion 241 of the load member 22 and the spacer 261. Further, when the movement of the heel surface 4 relative to the lower waist 2 is completed, the insertion portion 423 of the heel surface 4 comes to a position adjacent to the spacer 261.

  As described above, the side surface 3 and the heel surface 4 are respectively assembled (assembled) with respect to the lower waist 2 by moving the two side surfaces 3 and the two opposite heel surfaces 4 facing the lower waist 2. However, it is not always necessary to move the side surface 3 and the heel surface 4 with respect to the lower waist 2. For example, the two opposite side surfaces 3 and the two opposite collar surfaces 4 are held in a state of being incorporated in the lower waist 2 in advance, and the lower waist 2 is moved to engage the engagement portions 25, 26 of the lower waist 2. It is also possible to incorporate into the insertion part 323 of the side surface 3 and the insertion part 423 of the side surface 4. Further, by moving the lower waist 2, the two opposing side surfaces 3, and the two opposing heel surfaces 4, the engaging portions 25, 26 of the lower waist 2 are moved to the insertion portions 323, It is also possible to incorporate it into the nail 423 of the surface 4.

  As described above, when the lower waist 2, the two opposing side surfaces 3, and the two opposing heel surfaces 4 are assembled, the side surface 3 and the heel surface 4 are combined. Specifically, as shown in FIG. 4, the side surface 3 and the flange surface 4 that are adjacent to each other are brought into contact with the side plate 32 and the flange plate 42 in a vertical state. The side plate 32 and the side plate 42 are brought into contact with each other, and the side rail 31 and the side rail 41 are brought into contact with each other, and the end portion 411 of the side plate 41 and the edge 424 of the side plate 42 are formed on the side surface 3. Abuts against the protruding portion 312. At the same time, the edge 424 of the gutter plate 42 enters the gap 314 formed by the side plate 32 and the gutter clamping bar 34 and comes into contact with the reinforcing vertical bar 33. As a result, the portion of the gutter plate 42 along the gutter clamping bar 34 is sandwiched between the side plate 32 and the gutter clamping bar 34, and the side surface 3 and the gutter surface 4 are supported with each other. After the side surface 3 and the heel surface 4 are supported with respect to the four corners of the lower back 2, the side bar 31 and the heel bar 41 are fixed with the band 5.

  When fixing with the band 5, as shown in FIG. 4, the band 5 is wound around the end portion 311 of the side bar 31, and the band 5 is attached to the reinforcing vertical bar 33, the bar clamping bar 34, the side bar 31, and the bar 41. And extends along the longitudinal direction of the eaves frame 41 (along arrow B) and extends from the end 411 of the eaves frame 41 of the eaves surface 4 shown in FIG. It passes through the end portion 411 of the crosspiece 41, passes through the same gap 313a, and is wound from the end portion 311 of the side crosspiece 31 (not shown) to the end portion 411 side of the crosspiece 41 of the side plate 4 shown in FIG. By winding the band 5 as described above, the side surface 3 and the heel surface 4 are prevented from being tilted from the direction perpendicular to the lower waist 2.

  After the band 5 is wound, as shown in FIG. 5, the top plate 7 is placed on the side surfaces 3, 3 and the collar surfaces 4, 4 so as to face the lower waist 2. Before placing the top plate 7, the hollow member 71 that holds the packaged product 8 previously placed on the lower waist 2 is placed on the upper portion 81 of the packaged product 8. The cut-out member 71 has a shape covering the upper portion 81 of the packaged product 8, and is sandwiched between the top plate 7 and the packaged product 8 to prevent the packaged product 8 from moving during transportation. In this example, the hollow member 71 sandwiches the upper portion 81 of the packaged product 8 from the side surfaces 3 and 3 facing each other. Therefore, the hollow member 81 has a substantially U-shaped shape. However, the hollow member 71 is not limited to a substantially U-shape, and the shape is appropriately changed according to the shape of the upper portion 81 of the packaged product 8. In this example, the side surface 3 and the collar surface 4 are assembled after the packaged article 8 is placed on the lower back 2. However, for example, the side of the packaged article 8 is placed on the lower side 2. 3. It can be performed after the heel surface 4 is assembled, or it can be performed before the side surface 3 is assembled to the lower waist 2 and before the heel surface 4 is assembled. 4 can be performed before the side surface 3 is assembled, and when the package 8 is placed is determined based on various circumstances such as the size and weight of the package 8. Become.

  As described above, with the package 8 inside, the side surface 3 and the collar surface 4 are assembled to the lower waist 2 and the top plate 8 is placed. As shown in FIG. It winds by winding in the direction surrounding the side surface 3 and the lower waist 2. At this time, pressure is applied to the cutout member 71 from the top plate 7, and the pressure is transmitted to the upper portion 81 of the packaged product 8, so that the packaged product 8 is difficult to move on the lower waist 2. In this example, as shown in FIG. 6, the packaging box 1 is formed by winding the band 6 at four locations. In particular, the number of places where the band 6 is wound is not limited to four, and may be less or more than four depending on the size of the completed packaging box 1. Band 6 is usually tightened by a machine.

  In order to unpack the packaging box completed as described above, the bands 5 and 6 are cut with a knife such as a knife. The mounted top plate 7 is removed from the side surface 3 and the heel surface 4, and the assembled side surface 3 and heel surface 4 are removed from the lower waist 2. By lowering the package 8 from the lower waist 2, the lower waist 2, the side surface 3, and the collar surface 4 return to the state before being assembled in the packaging box 1.
