Description

Technical Field

[0001] The invention relates to a pallet component structure and a packaging system. Background Art

[0002] Conventionally, a frame structure 29 (29) formed of a sheet material and arranged along the four sides of the outer periphery of the pallet part 9 is formed by bending and fixing the deck portion of the pallet part 9 on which packaged goods or a packaged body 25 can be transported in a unit load manner. Fig.13 ). By forming the frame structure 29 of the side wall portion on the four sides, the packaged goods or the packaged body 25 loaded on the pallet part 9 can be fully suppressed from moving in the front, back, left and right directions due to vibration or impact during transportation. In addition, by combining the frame structure 29 with the outer shell box 21, the movement of the outer shell box 21 can be further suppressed.

[0003] Conventionally, the frame forming part 1 constituting such a frame structure 29 is composed of a sheet-like part, and after the four sides of the outer periphery thereof are erected to form the side wall part, they are joined together by additional processing such as a bonding part, a joining part or a fixing mechanism 27 of an adhesive, thereby forming the frame structure 29 ( Fig.14 , Fig.15 ).

[0004] In addition, when the frame structure portion of the pallet part assembly composed of the pallet part 9 and the frame structure forming part 1 is formed and fixed during the manufacturing process of the pallet manufacturer, the height of the pallet part assembly increases during the period when the pallet part assembly is circulated from the pallet manufacturer to the manufacturer of the packaged body 25, and the number of loading layers of the pallet part assembly during transportation is reduced, resulting in a problem of reduced number of pallet part assemblies transported during truck transportation and increased transportation costs.

[0005] As a countermeasure to this problem, Fig.16 As shown, it is also considered to change the size relationship of the overlapping pallet component components, specifically, to make the pallet component component directly below a certain pallet component component overlap relatively small. However, in this way, the outer shell box placed on the upper part cannot be completely placed on the pallet component component, because the compressive strength of the outer shell box 21 is lost, and in addition, the frame structure forming part 1 protrudes outward more than the lower pallet component component, resulting in the frame structure forming part 1 contacting with other goods and possibly being damaged.

[0006] Therefore, in the past, Fig.14 As shown, the pallet component structure is transported in an open state without erecting the side wall, and the manufacturer of the packaged body 25 as a user erects the side wall when using it, and forms the frame structure 29 by additional processing operations such as tape pasting operations to combine the side wall. Such additional processing operations are burdensome for the operator.

[0007] In addition, in this case, if Fig.17 As shown in the figure, in the conventional pallet component structure and its conveying method, due to the open side wall, a dead zone 31 indicated by oblique lines is generated directly below the side wall. As a result, although the number of stacked layers in the state where the side wall is erected is not reduced, the loading efficiency during truck conveying is still reduced. In addition, when the thin side wall is circulated in a protruding state, there is a problem that the side wall is damaged due to contact with other goods.

[0008] The purpose of Patent Document 1 is to further improve the solution to the problem of deviation and movement of packaging boxes placed on a pallet during cargo loading and unloading operations or transportation, while maximizing the amount of paper used and greatly improving the strength characteristics of a paper pallet. Therefore, the paper pallet has a top plate formed by wrapping a core plate with a surrounding plate, a spacer wrapped in a square cylinder formed by continuously forming a top plate, a bottom plate and two side panels, and a spacer formed by wrapping a longitudinal paper tube in a transverse square cylinder, and a plurality of rows of reinforcing strips are attached to the lower surface of the bottom plate.

[0009] However, the deviation prevention sheet is only provided on two opposing side surfaces, and the frame structure portion surrounding the four side surfaces of the packaging box is not formed by the deviation prevention sheet. In addition, since the deviation prevention sheet and the packaging box are fixed only by the insertion sheet provided on the deviation prevention sheet, the strength is insufficient, especially when the heavy packaging box is prevented from moving in the front, back, left, and right directions. Although the structure in which the deviation prevention sheet is provided on the four sides is also shown, since the frame structure portion is not pre-bonded, the additional processing operation for forming the frame structure portion when using the pallet is a burden for the operator. When the packaging process is automated by a robot, the additional processing operation will also increase the difficulty of the process automation and complicate the process.

[0011] [Patent Document 2] (Japan) Patent No. 5240464 Summary of the invention

[0012] Therefore, the purpose of the present invention is to improve the loading efficiency of the pallet part assembly during circulation compared with the past, and to prevent damage to parts during circulation, thereby eliminating the load of additional processing operations of the frame structure that was previously generated when the pallet part assembly was used, thereby being able to form a simple frame structure and automating the packaging process.

[0013] The technical solution of the present invention relates to a pallet part structure for loading a packaged body, which includes: a pallet part, and a frame structure forming part that can be folded into a flat shape and is fixed on the pallet part. When the adjacent frame structure parts of the frame structure forming part are pre-combined, the frame structure forming part can be folded into a flat shape.

[0014] The loading efficiency of the pallet component assembly during circulation is improved compared with the past, and the damage of the components during circulation is prevented. Furthermore, the load of additional processing operations of the frame structure part generated when the pallet component assembly is used in the past is eliminated, a simple frame structure part can be formed, and the packaging process is automated.

[0032] Hereinafter, a frame structure and a pallet component structure according to an embodiment of the present invention will be described with reference to the drawings.

[0033] Figure 1 and Figure 2 FIG. 1 is a schematic perspective view of a pallet component assembly 10 according to an embodiment of the present invention.

[0034] The pallet component structure 10 according to the embodiment of the present invention is used to load the packaged object 25 ( Fig.13 ) of a pallet component structure 10, comprising a pallet component 9 and a frame structure forming component 1 that can be folded into a flat shape and is fixed to the pallet component 9. The frame structure forming component 1 involved in the embodiment of the present invention has a bottom surface 2 and four side wall portions 3 adjacent to the outer periphery of the bottom surface 2, and is located on the pallet component 9.

[0035] exist Figure 1 In the embodiment, the side wall portion 3 of the frame structure forming part 1 is erected, and the frame structure forming part 1 forms a frame structure body erected along the four sides of the outer periphery of the pallet part 9. Figure 2In the embodiment, the side wall portion 3 of the frame structure forming part 1 is bent inwardly, and when viewed from above, the frame structure forming part 1 does not protrude from the area of ​​the pallet part 9, but is stored inside the pallet part 9. That is, in a state where the adjacent frame structure portions of the frame structure forming part 1 are pre-connected by the connecting portion 5, the frame structure forming part 1 can be folded into a flat state.

[0036] The pallet component 9 is composed of a lower plate, a block component arranged on the lower plate, an upper plate component arranged on the block component, etc. The pallet component 9 has a fork insertion port for inserting a fork of a forklift. In addition, the detailed structure of the pallet component is recorded in, for example, Patent Document 2, and will not be repeated here.

[0037] The frame structure forming part 1 is fixed to the flat deck plate constituting the pallet member 9 by screws or the like.

[0038] exist Figure 1 In the embodiment, two adjacent side walls 3 are simply joined to each other by gluing or stapling by the pallet manufacturer through the joining portion 5 which is a part of the side wall 3. The joining portion 5 is joined by the pallet manufacturer, so there is no need for the manufacturer of the packaged body 25 as the user to perform the joining operation.

[0039] Figure 3 1 is a schematic front view showing a state where the pallet component assembly 10 according to the embodiment of the present invention is loaded.

[0040] As shown in the figure, according to the present embodiment, it is possible to generate a dead zone 31 ( Fig.17 ) when loading the pallet component assembly 10.

[0041] According to the pallet component structure 10 according to the embodiment of the present invention, the conventional problems can be solved for the following reasons.

[0042] ·like Figure 2 As shown, since the frame structure forming part 1 can be folded inward when the part is circulated, Figure 3 As shown, the dead zone during transportation that was previously generated can be eliminated, and the loading efficiency during truck transportation can be improved.

[0043] ·like Figure 2 As shown, since the frame structure forming part 1 can be folded inward when the parts are circulated, the thin side wall part 3 is placed on the upper plate part of the pallet part 9 and will not contact with other goods as in the past, so damage to the side wall part 3 can be prevented.

[0044] Since the adjacent frame structure parts (specifically, the side wall parts 3) of the frame structure forming part 1 are flatly folded in a pre-joined state, there is no need for complicated additional processing of joining the four corners to form the frame structure after the side wall parts are erected as in the past. In addition, since the side wall parts 3 on the four sides are erected in a linked manner (semi-automatically) when the side wall parts 3 are erected, the frame structure part can be easily formed. Therefore, the conventional operation that is burdensome for the operator can be simplified, and the operation process of the robot can be simplified.

[0045] Figure 4 1 is a schematic plan view of a frame structure forming component 1 according to a fifth embodiment of the present invention. Figure 4 (a) shows a schematic top view of the frame structure forming part 1 before being combined. Figure 4 (b) shows a schematic top view of the frame structure forming part 1 after folding.

[0046] exist Figure 4 In (a), the frame structure forming part 1 has a quadrilateral shape as a whole, and has a bottom surface 2, four side wall parts 3 adjacent to the outer periphery of the bottom surface 2 to form a frame structure part, a joint part 5 for joining the four corners of the frame structure forming part 1, and a bending line 8 for folding the side wall part 3. As shown in the figure, four cutouts 6 extending parallel to the left and right sides of the frame structure forming part 1 are formed on the frame structure forming part 1. Therefore, the left and right side wall parts 3 have joint parts 5 located in the four corners of the frame structure forming part 1 at the top and bottom. Figure 4 (a) is an expanded view of the frame structure forming part 1, and these joints 5 are pre-joined with a part of the side wall portion 3 adjacent to the cutout 6. The area shown by the oblique lines in the figure is the overlapping area / joining area of ​​the joint 5 and the adjacent side wall portion 3. The cutout 6 before joining is formed as a slit and has no width.

[0047] The folding folding lines 8 are formed in two inclined lines on the two opposing side walls 3 in order to fold the side walls 3 to form the frame structure, and function as mountain folding lines when folded in a plan view. In addition, the dotted lines in the figure function as valley folding lines. That is, when the connecting part 5 is connected, the dotted lines are valley folded and the folding lines 8 are mountain folded to form a Figure 4 By bending the bending line 8 into a mountain fold, the side wall portion 3 of the frame structure forming part 1 can be completely folded to the inner side of the support plate part 9 ( Figure 4 (b)).

[0048] Figure 5 1 is a schematic plan view of a frame structure forming component 1 according to a second embodiment of the present invention. Figure 5 (a) shows a schematic top view of the frame structure forming part 1 before being combined. Figure 5 (b) shows a schematic top view of the frame structure forming part 1 after folding.

[0049] The folding folding lines 8 are formed in two inclined lines on the two opposing side walls 3 in order to fold the side walls 3 to form the frame structure, and function as valley folding lines when folded in a plan view. In addition, the dotted lines in the figure function as valley folding lines. That is, when the connecting part 5 is connected, the dotted lines are valley folded to valley fold the folding lines 8 to form a valley folding line. Figure 5 By bending the bending line 8 into a valley fold, the upper and lower side wall portions 3 of the frame structure forming part 1 are folded to the inner side of the pallet part 9, and the left and right side wall portions 3 are folded to the outer side of the pallet part 9 ( Figure 5 (b)). This can also eliminate Fig.17 The dead zone on the left and right is shown, that is, it can be Figure 5 The pallet component structure 10 is adjacently arranged in the vertical direction of Figure 3 As shown, the pallet component structure 10 is loaded in the height direction.

[0050] Figure 6 1 is a schematic plan view of a frame structure forming component 1 according to a third embodiment of the present invention. Figure 6 (a) shows a schematic top view of the frame structure forming part 1 before being combined. Figure 6 (b) shows a schematic top view of the frame structure forming part 1 after folding.

[0051] In this embodiment, Figure 4 Unlike the first embodiment, in order to fold the side wall portion 3 to form the frame structure portion, one bending line 8 for folding is obliquely provided in the joint 5 on the side wall portion 3 having the joint 5, one bending line is obliquely provided on the side wall portion 3, and two bending lines are obliquely provided on the side wall portion 3 opposite to the side wall portion 3, and further, one bending line is obliquely provided on the side wall portion 3 adjacent to the joint 5 having the bending line 8 via the cutout 6. These serve as mountain fold lines. In addition, the dotted lines in the figure function as valley fold lines. That is, in a state where the joint 5 is connected, by valley folding the dotted lines and mountain folding the bending lines 8, Figure 6 Thus, since the four side wall portions 3 are folded on the adjacent side wall portions 3, respectively ( Figure 6 (b)), the posture of the side wall portion 3 in the folded state during storage or transportation of parts can be stably fixed.

[0052] According to the frame structure forming part 1 involved in the first to third embodiments, the coupling part 5 for coupling the four corners of the frame structure forming part 1 has a quadrilateral shape. Thus, a sufficient area can be used to couple the four corners of the frame structure forming part 1, thereby ensuring a sufficient fixing force.

[0053] Figure 7 1 is a schematic plan view of a frame structure forming component 1 according to a fourth embodiment of the present invention. Figure 7 (a) shows a schematic top view of the frame structure forming part 1 before being combined. Figure 7 (b) shows a schematic top view of the frame structure forming part 1 after folding.

[0054] In this embodiment, Figure 4 Unlike the first embodiment, the cutout 6 has a triangular shape, and similarly, the connecting portion 5 also has a triangular shape. The connecting portion 5 overlaps on the oblique line portion of a portion of the side wall portion 3 adjacent to the cutout 6, and is fixed to each other in advance by gluing or staplers.

[0055] The folding folding line 8 is formed obliquely on the left side wall 3 and obliquely on the right side wall 3 opposite to the left side wall 3 in order to fold the side wall 3 of the frame structure. These folding folding lines function as valley folding lines. In addition, the dotted lines in the figure function as valley folding lines. That is, when the connecting part 5 is connected, the dotted lines are valley folded and the folding lines 8 are mountain folded to form a valley folding line. Figure 7 By bending the bending line 8 into a mountain fold, the side wall portion 3 of the frame structure forming part 1 can be completely folded to the inner side of the support plate part 9 ( Figure 7 (b)).

[0056] According to the frame structure forming part 1 involved in the fourth embodiment, the connecting part 5 for connecting the four corners of the frame structure forming part 1 has a triangular shape. By forming the triangular cutout 6 of the triangular connecting part 5, the number of overlapping connecting parts 5 when the connecting part 5 is folded is reduced by one compared with the case of a quadrilateral, so that the instability of the posture caused by the overlap when folded can be suppressed.

[0057] In addition, if Figure 1 As shown, according to the embodiment of the present invention, the side wall portion 3 forming the frame structure portion is provided with a coupling hole 7, and the coupling hole 7 can be inserted with a coupling part 23 for coupling the side wall portion 3 with the outer shell box 21. Thus, the frame structure forming part 1 and the outer shell box 21 can be coupled by the coupling part 23, and the two can be firmly fixed ( Fig.13 ).

[0058] Figure 81 is a schematic plan view of a frame structure forming component 1 according to a fifth embodiment of the present invention. Figure 8 Shown is a schematic top view of the frame structure forming part 1 before being combined.

[0059] Fig. 9 1 is a schematic diagram of the main parts of the frame structure forming component 1 involved in this embodiment when it is folded. Fig. 9 (a) is a schematic three-dimensional view of the erected frame structure forming part 1, Fig. 9 (b) is a schematic three-dimensional view of the frame structure forming part 1 when folded.

[0060] like Figure 8 As shown in FIG. 1 , the incision 13 for inserting the joint 5 when folding is provided on the side wall 3 forming the frame structure. The incision 13 extends in an arc shape from the joint 11 between the bottom surface 2 and the side wall 3 adjacent to the bottom surface 2 toward the outside of the side wall 3. Fig. 9 As shown in (a), as long as the upright side wall portion 3 is bent into a valley fold at the bending line 8, as shown in Fig. 9 As shown in (b), the corner of the erected side wall portion 3 can be inserted into the cutout 13. Thus, the folded state of the side wall portion 3 can be maintained in the state of being inserted into the cutout 13.

[0061] Fig.10 1 is a schematic plan view of a frame structure forming component 1 according to a sixth embodiment of the present invention. Fig.10 Shown is a schematic top view of the frame structure forming part 1 before being combined.

[0062] Fig.11 ) is a schematic diagram of the main parts of the frame structure forming part 1 involved in this embodiment when it is folded.

[0063] like Fig.10 As shown in FIG. 1 , the side wall portion 3 forming the frame structure is provided with a fixing portion 15 for fixing the side wall portions 3 to each other and two through holes 17 and 19 for inserting the fixing portion 15. The through holes 17 and 19 are provided at positions overlapping with the fixing portion 15 when the side wall portion 3 is folded. The fixing portion 15 has a T-shape. Thus, as shown in FIG. Fig.11 As shown in FIG. 1 , when the frame structure forming part 1 is folded, the fixing portion 15 can be erected and inserted into the two through holes 17 and 19, and the folded state of the side wall portion 3 can be hooked to the T-shaped portion of the fixing portion 15 and maintained.

[0064] In addition, refer to Figure 1In the frame structure forming part 1 involved in the embodiment of the present invention, the connecting parts 5 for connecting the four corners of the frame structure forming part 1 are overlapped and connected on the outside of the side wall part 3. Since the connecting parts 5 for connecting the four corners of the frame structure forming part 1 do not enter the inside of the frame structure part, it is possible to ensure sufficient storage space inside the frame structure part.

[0065] on the other hand, Fig.12 1 is a schematic perspective view of a frame structure forming component 1 according to another embodiment of the present invention.

[0066] As shown in the figure, the four corners of the coupling part 5 for coupling the frame structure forming part 1 are overlapped and coupled on the inner side of the side wall part 3. Since the four corners of the coupling part 5 for coupling the frame structure forming part 1 do not protrude to the outside of the frame structure part, it is possible to suppress interference (damage caused by friction, etc.) of the coupling part 5 when the pallet part is transported adjacent to other pallet parts.

[0067] The frame structure forming component 1 according to the embodiment of the present invention is formed of corrugated cardboard. By forming the frame structure forming component 1 of corrugated cardboard, which is a material with excellent recyclability, the recycling of the pallet component component 10 can be promoted.

[0068] In the frame structure forming component 1 according to the embodiment of the present invention, the coupling parts 5 for coupling the four corners of the frame structure forming component 1 are coupled by staple coupling. Thus, sufficient fixing force of the side wall portion 3 of the frame structure forming component 1 can be ensured.

[0069] In addition, in the frame structure forming part 1 according to the embodiment of the present invention, the connecting parts 5 for connecting the four corners of the frame structure forming part 1 are connected by an adhesive. Therefore, since a connecting member made of a material different from that of the frame structure forming part 1 is not required, it is not necessary to disassemble and separate the frame structure forming part 1 when it is discarded.

[0070] In the pallet component structure 10 according to the embodiment of the present invention, the pallet component 9 as the pallet base structure is a pallet made of corrugated cardboard.

[0071] In the pallet component structure 10 according to the embodiment of the present invention, the pallet component 9 is a pallet made of plywood. Since the pallet made of plywood has high rigidity, the pallet component structure 10 with high rigidity can be realized.

[0072] In addition, in the pallet component structure 10 according to the embodiment of the present invention, the frame structure forming component 1 and the pallet component 9 are bonded together by an adhesive. Therefore, since a bonding component made of a material different from that of the frame structure forming component 1 is not required, the frame structure forming component 1 does not need to be disassembled or separated when it is discarded.

[0073] In addition, in the pallet component structure 10 according to the embodiment of the present invention, the frame structure forming component 1 and the pallet component 9 are joined by stitches. Thus, a strong fixing force can be ensured.

[0074] In addition, in the pallet component structure 10 according to the embodiment of the present invention, the frame structure forming component 1 and the pallet component 9 are fastened and joined by screws. Thus, a strong fixing force can be ensured.

[0075] According to the embodiment of the present invention, in the packaging system including the pallet component assembly 10 and the object to be packaged 25 placed on the pallet component assembly 10, the object to be packaged 25 is an image forming apparatus.

[0076] As described above, according to the present invention, the following effects can be obtained.

[0077] Eliminate the dead zone 31 ( Fig.17 ), which can improve the loading efficiency of truck transportation ( Figure 3 ).

[0078] Since the thin side wall 3 is placed on the top plate of the pallet part 9, it is different from the past in that it does not contact other goods, so it can prevent the side wall 3 from being damaged ( Figure 2 ).

[0079] There is no need for additional processing work at the four corners to form the frame structure of the erected side wall 3 as in the past, and when the side wall 3 is erected, the side wall 3 at the four sides is semi-automatically erected. As a result, since the frame structure can be easily formed, there is no need for heavy-duty operations for the operator, and the operation process can be easily automated by a robot.
