With reference to FIG. 3, the plate pad 20 is formed with four first engaging holes 23A to 23D and four second engaging holes 21A to 21D corresponding to each of the four cushioning materials 30A to 30D. Each of the four first engaging holes 23A to 23D is paired with any of the four second engaging holes 21A to 21D. Here, the first engaging hole 23A and the second engaging hole 21A are paired, the first engaging hole 23B and the second engaging hole 21B are paired, and the first engaging hole 23C and the second engaging hole 23C are paired. The engaging hole 21C is paired, and the first engaging hole 23D and the second engaging hole 21D are paired.

Of the four first engaging holes 23A to 23D formed in the plate pad 20, the first engaging hole 23A is the reference engaging hole. The relative position of the reference engaging hole with respect to the pallet 10 is predetermined. Since the first engaging hole 23A, which is the reference engaging hole, is formed in the plate pad 20, the first engaging hole 23A, which is the reference engaging hole, is in a predetermined relative position with the pallet 10. The relative position between the plate pad 20 and the pallet 10 is determined. Therefore, the reference engaging hole is prevented so that the plate pad 20 does not protrude from the pallet 10 in a state where the first engaging hole 23A, which is the reference engaging hole, is in a predetermined relative position with the first positioning portion 15A. The position of the first engaging hole 23A in the plate pad 20 is determined.

The four second engaging protrusions 31A to 31D are shorter than the four first engaging protrusions 33A to 33D.

Further, the cushioning material 30A has a side wall 35A extending upward from the bottom surface. Since the cushioning material 30A has the side wall 35A, the lateral movement of the product 100 can be restricted. Further, in the state where the outer box 40 is covered, the lateral movement of the side walls 35A of each of the cushioning materials 30A to 30D is restricted by the side surface of the outer box 40. Therefore, when the product 100 receives a force to move laterally, the side walls 35A of each of the cushioning materials 30A to 30D receive a force laterally from the product 100, but the side wall 35A is supported by the side surface of the outer box 40. The force received from the product 100 is received not only by the side wall 25A but also by the side wall 25A and the side surface of the outer box 40.

FIG. 5 is a view of the combined state of the pallet, the plate pad, and the four cushioning materials as viewed from below the pallet. For the sake of explanation, the pallet 10 shows only two square timbers 13A and 13B and six plate members 11A to 11F.

The second positioning unit 15B includes the second side surface 16B and the third side surface 17A as restraining surfaces. The third positioning unit 15C includes a second side surface 16B and a fourth side surface 17B as restraining surfaces. The fourth positioning unit 15D includes the first side surface 16A and the fourth side surface 17B as restraining surfaces. In the first to fourth positioning units 15A to 15D, two pairs located diagonally are classified into the same set. Specifically, the first positioning unit 15A and the third positioning unit 15C form the first set, and the second positioning unit 15B and the fourth positioning unit 15D form the second set.

In the first set, the first positioning unit 15A has a first side surface 16A and a third side surface 17A as deterrent surfaces, and the third positioning unit 15C has a second side surface 16B and a fourth side surface 17B as deterrent surfaces.

It is in a positional relationship facing 17B.

In the second set, the second positioning unit 15B has a second side surface 16B and a third side surface 17A as deterrent surfaces, and the fourth positioning unit 15D has a first side surface 16A and a fourth side surface 17B as deterrent surfaces. Have. The second side surface 16B of the second positioning unit 15B and the first side surface 16A of the fourth positioning unit 15D are in a positional relationship facing each other, and the third side surface 17A of the second positioning unit 15B and the fourth side surface of the fourth positioning unit 15D. It is in a positional relationship facing 17B.

The positions of the first engaging holes 23A, which are the reference engaging holes formed in the plate pad 20, with respect to the first to fourth positioning portions 15A to 15D are predetermined. Therefore, the relative position of the first engaging hole 23A, which is the reference engaging hole, with respect to the pallet 10 is predetermined.

Here, various steps up to assembling the packing device 1 up to the state shown in FIG. 5 will be described in order. First, the plate pad 20 is placed on the pallet 10, and the cushioning material 30A is assembled into the first engaging hole 23A and the second engaging hole 21A, which are the reference engaging holes. In this case, the first engaging convex portion 33A of the cushioning material 30A is inserted into the first engaging hole 23A, and the second engaging convex portion 31A is inserted into the second engaging hole 21A. Since the second engaging hole 21A is larger in size than the second engaging convex portion 31A and the first engaging hole 23A is larger in size than the first engaging convex portion 33A, the cushioning material 30A and the plate are at this stage. The relative position with respect to the pad 20 and the relative position between the pallet 10 and the plate pad 20 are not determined.

Next, the cushioning material 30C is assembled into the first engaging hole 23C and the second engaging hole 21C located diagonally to the first engaging hole 23A. In this case, the first engaging convex portion 33C is inserted into the first engaging hole 23C before the second engaging convex portion 31C of the cushioning material 30C is inserted into the second engaging hole 21C. Since the first engaging hole 23C is larger in size than the first engaging convex portion 33C, the first engaging convex portion 33C penetrates the first engaging hole 23C and protrudes below the plate pad, and the first engaging hole 23C of the pallet 10 is formed. 3 It comes into contact with the positioning portion 15C. In this state, when the second engaging convex portion 31C is pushed into the second engaging hole 21C, the first engaging convex portion 33C is in contact with the second side surface 16B and the fourth side surface 17B of the third positioning portion 15C. Therefore, a force is applied by the second engaging convex portion 31C to push the plate pad 20 through the second engaging hole 21C in the direction from the first engaging hole 23C toward the second engaging hole 21C. As a result, the plate pad 20 moves in the direction from the first engaging hole 23C to the second engaging hole 21C.

On the other hand, since the first engaging convex portion 33A of the cushioning material 30A penetrates the first engaging hole 23A, the plate pad 20 moves in the direction from the first engaging hole 23C toward the second engaging hole 21C. Then, the first engaging convex portion 33A comes into contact with the first side surface 16A and the third side surface 17A of the first positioning portion 15A, so that the relative positions of the cushioning material 30A and the pallet 10 are determined. Further, the movement of the plate pad 20 is restricted by the first engaging hole 23A coming into contact with the first engaging convex portion 33A.

After the movement of the plate pad 20 is restricted, the slit 25C is deformed so that the second engaging convex portion 31C is inserted into the second engaging hole 21C. Thereby, the relative position between the cushioning material 30C and the pallet 10 is determined. At this stage, due to the restoring force of the slit 25C, the second engaging convex portion 31C of the cushioning material 30C receives a force in the direction from the slit 25C toward the first engaging hole 23C, and as a reaction force thereof, the cushioning material 30A The first engaging convex portion 33A receives a force in the direction from the slit 25C toward the first engaging convex portion 33A. Therefore, the force of the first engaging convex portion 33C of the cushioning material 30C toward the third positioning portion 15C and the force of the first engaging convex portion 33A of the cushioning material 30A toward the first positioning portion 15A. , Are balanced.

The force received by the first engaging convex portion 33A of the cushioning material 30A from the slit 25C includes a component of the force of the component perpendicular to each of the first side surface 16A and the third side surface 17A of the first positioning portion 15A. Similarly, the force received by the first engaging convex portion 33C of the cushioning material 30C from the slit 25C includes a component of the force of the component perpendicular to each of the second side surface 16B and the fourth side surface 17B of the third positioning portion 15C.

Next, one of the cushioning materials 30B and 30D is assembled in order. For example, the first engaging convex portion 33B is inserted into the first engaging hole 23B before the second engaging convex portion 31B of the cushioning material 30B is inserted into the second engaging hole 21B. Since the first engaging hole 23B is larger in size than the first engaging convex portion 33B, the first engaging convex portion 33B penetrates the first engaging hole 23B and protrudes below the plate pad, and the first engaging hole 23B of the pallet 10 is formed. 2 It comes into contact with the positioning portion 15B. In this state, when the second engaging convex portion 31B is pushed into the second engaging hole 21B, the first engaging convex portion 33B is in contact with the second side surface 16B and the third side surface 17A of the second positioning portion 15B. Since the relative positions of the plate pad 20 and the pallet 10 are determined, the slit 25B is deformed and the second engaging convex portion 31B is inserted into the second engaging hole 21B. Thereby, the relative position between the cushioning material 30B and the pallet 10 is determined. In this state, the restoring force of the slit 25B causes the second engaging convex portion 31B of the cushioning material 30B to receive a force in the direction from the slit 25B toward the first engaging hole 23B.

Finally, the first engaging convex portion 33D is inserted into the first engaging hole 23D before the second engaging convex portion 31D of the cushioning material 30D is inserted into the second engaging hole 21D. Since the first engaging hole 23D is larger in size than the first engaging convex portion 33D, the first engaging convex portion 33D penetrates the first engaging hole 23D and protrudes below the plate pad, and the first engaging hole 23D of the pallet 10 is formed. 4 Abuts on the positioning unit 15D. In this state, when the second engaging convex portion 31D is pushed into the second engaging hole 21D, the first engaging convex portion 33D is in contact with the first side surface 16A and the fourth side surface 17B of the fourth positioning portion 15D. Since the relative positions of the plate pad 20 and the pallet 10 are determined, the slit 25D is deformed and the second engaging convex portion 31D is inserted into the second engaging hole 21C. Thereby, the relative position between the cushioning material 30D and the pallet 10 is determined. In this state, the restoring force of the slit 25D causes the second engaging convex portion 31D of the cushioning material 30D to receive a force in the direction from the slit 25D toward the first engaging hole 23D.

The force received by the first engaging convex portion 33B of the cushioning material 30B from the slit 25B includes the force of the component perpendicular to each of the second side surface 16B and the third side surface 17A of the second positioning portion 15B. Further, the force received by the first engaging convex portion 33D of the cushioning material 30D from the slit 25D includes the force of the component perpendicular to each of the first side surface 16A and the fourth side surface 17B of the fourth positioning portion 15A.

As described above, the packing device 1 in the present embodiment includes the pallet 10, the plate pad 20 placed on the pallet 10, and the cushioning materials 30A to 30D arranged on the plate pad 20. The pallet 10 has positioning portions 15A to 15D below the upper surface in contact with the plate pad 20, and the first engaging convex portions 33A to 33D of each of the cushioning materials 30A to 30D are formed on the plate pad 20. 1 It penetrates any of the engaging holes 23A to 23D and engages with any of the positioning portions 15A to 15D. Therefore, since each of the first engaging convex portions 33A to 33D engages with any of the positioning portions 15A to 15D, the cushioning materials 30A to 30D are parallel to the plate pad 20 at the first engaging convex portions 33A to 33D. Directional movement is restricted. Since the first engaging convex portions 33A to 33D are provided on the bottom surfaces of the cushioning materials 30A to 30D, the distance between the position where the external force is received and the first engaging convex portions 33A to 33D in the cushioning materials 30A to 30D is made as large as possible. can do. For example, the position where the cushioning material 30A receives the external force, for example, the portion between the side wall 35A and the first engaging convex portion 33A is elastically deformed to attenuate the external force and reduce the force received by the side wall 35A from the product 100. can do. Further, the first engaging convex portion 33A is elastically deformed, so that the cushioning material 30A slides on the plate pad 20 with respect to the plate pad 20. As a result, the external force can be attenuated and the force received by the side wall 35A from the product 100 can be reduced. Further, the force received by the first engaging convex portion 33A can be reduced by the frictional force between the bottom surface of the cushioning material 30A and the plate pad 20, and the force applied to the first engaging convex portion 33A can be reduced. Can be done. As a result, the cushioning materials 30A to 30D can be prevented from being damaged by the external force received from the product 100. Further, the cushioning materials 30A to 30D can be made hard to be damaged, and the ability to protect the product 100 can be maintained as much as possible. Further, when the side wall 35A receives an external force from the product 100, the side wall 35A comes into contact with the side surface of the outer box 40, so that the external force received from the product 100 can be received not only by the side wall 35A but also by the side surface of the outer box 40. Therefore, the external force received from the product 100 can be dispersed to reduce the force received by the side wall 35A. Further, even if at least one of the cushioning materials 30A to 30D, for example, the engaging convex portion 33A of the cushioning material 30A is damaged by an external force received from the product 100, the side wall 35A of the cushioning material 30A is not damaged. Can maintain the cushioning function.

Further, the first positioning unit 15A is paired with the third positioning unit 15C, and the first side surface 16A as the deterrent surface of the first positioning unit 15A and the second side surface 16B as the deterrent surface of the third positioning unit 15C face each other. Then, the third side surface 17A as the deterrent surface of the first positioning unit 15A and the fourth side surface 17B as the deterrent surface of the third positioning unit 15C face each other. Further, the second positioning unit 15B is paired with the fourth positioning unit 15D, and the second side surface 16B as the deterrent surface of the second positioning unit 15B and the first side surface 16A as the deterrent surface of the fourth positioning unit 15D face each other. Then, the third side surface 17A as the deterrent surface of the second positioning unit 15B and the fourth side surface 17B as the deterrent surface of the fourth positioning unit 15D face each other. The first engaging convex portions 33A to 33D of the cushioning materials 30A to 30D, for example, the first engaging convex portions 33A of the cushioning material 30A correspond to the first side surface 16A and the third side surface 17A which are the restraining surfaces of the positioning portion 15A. At least one of the cushioning material 30A or the cushioning material 30C, in which the cushioning material 30C, is urged in a direction intersecting the second side surface 16B and the fourth side surface 17B of the positioning portion 15C with which the cushioning material 30A or the cushioning material 30C is engaged. do. Therefore, the cushioning material 30A can be urged to the first side surface 16A of the positioning unit 15A, and the cushioning material 30C can be urged to the second side surface 16B of the positioning unit 15C. The cushioning material 30A can be urged on the side surface 17A, and the cushioning material 30C can be urged on the fourth side surface 17B of the positioning portion 15C. Therefore, the relative positions of the plurality of cushioning materials 30A to 30D and the pallet 10 can be appropriately determined.

Further, the first engaging holes 23A to 23D are larger in size than the first engaging convex portions 33A to 33D of the cushioning materials 30A to 30D, respectively, and the second engaging convex portions 31A to 31D of the cushioning materials 30A to 30D, respectively. Is inserted into any of the second engaging holes 21A to 21D so that each of the first engaging convex portions 33A to 33D engages with any of the positioning portions 15A to 15D. The position of ~ 21D is determined. When the second engaging protrusions 31A to 31D are inserted into any of the second engaging holes 21A to 21D, the relative positions of the cushioning materials 30A to 30D and the plate pad 20 are determined. Further, since the positions of the second engaging holes 21A to 21D are determined so that each of the first engaging convex portions 33A to 33D engages with any of the positioning portions 15A to 15D, the cushioning materials 30A to 30D and the pallet 10 are used. The relative position with is determined. Therefore, the cushioning materials 30A to 30D determine the relative positions of the pallet 10 and the plate pad 20. Further, since the first engaging protrusions 33A to 33D penetrate any of the larger first engaging holes 23A to 23D, the relative position between the plate pad 20 and the cushioning materials 30A to 30D is the first engagement. It can be determined by the second engaging convex portions 31A to 31D and the positioning portions 15A to 15D without being affected by the combined convex portions 33A to 33D. Therefore, the work of positioning the cushioning materials 30A to 30D on the plate pad 20 can be facilitated.

Further, of the first engaging holes 23A to 23D, the first engaging hole 23A is a reference engaging hole whose relative position is determined with respect to the positioning portions 15A to 15D of the pallet 10, so that the reference engaging hole is, for example, a reference engaging hole. When the cushioning material 30A penetrating the first engaging hole 23A comes into contact with the restraining surface of the positioning portion 15A, the plate pad 20 and the pallet 10 are brought into a predetermined relative position. Therefore, the plate pad 20, the pallet 10, and the cushioning materials 30A to 30D can be set to predetermined relative positions.

The second engaging hole 21B and the first engaging hole 23B are arranged on a straight line parallel to the direction in which the corresponding cushioning material 30B is urged, and the second engaging hole 21C and the first engaging hole 23B are arranged. The 23C is arranged on a straight line parallel to the direction in which the corresponding cushioning material 30C is urged, and the second engaging hole 21D and the first engaging hole 23D have the corresponding cushioning material 30D. It is placed on a straight line parallel to the direction of urging. Therefore, the force urged by the cushioning materials 30B to 30D can be efficiently used.

Since the slit 25C extending to the opposite side of the positioning portion 15C corresponding to the joint hole 23C is formed in the plate pad 20, the second engaging convex portions 33A and 33C of the cushioning materials 30A and 30C, respectively, are formed in the second engaging hole 23A. The plate pad 20 is deformed at the portion where the slit 25C is formed at the stage of being inserted into the sheets and 23C, respectively, but the restoring force of the plate pad 20 causes the second engaging convex portion 31C of the cushioning material 30C to be inserted into the positioning portion 15C. Since the cushioning materials 30A and 30C are urged toward each other, the cushioning materials 30A and 30C can be brought into contact with the opposing restraining surfaces of the pair of positioning portions 15A and 15C.

<First modification>
The pair of positioning portions, for example, the second engaging holes 21A and 21C corresponding to the first positioning portion 15A and the third positioning portion 15C and the first engaging holes 23A and 23C are arranged on the same straight line. preferable. Similarly, the second engaging holes 21B and 21D corresponding to the pair of positioning portions, the second positioning portion 15B and the fourth positioning portion 15D, and the first engaging holes 23B and 23D are arranged on the same straight line. Is preferable. As a result, it is possible to prevent the generation of couples and prevent the plate pad 20 from rotating with respect to the pallet 10.

<Second modification>
The second engaging holes 21A to 21D may have at least one second reference engaging hole whose position is defined relative to the positioning portions 15A to 15D of the pallet 10. In this case, it is not necessary to use the first engaging hole 23A as the reference engaging hole.

For example, the second engaging hole 21A may be used as the second reference engaging hole. Since the position of the second engaging hole 21A, which is the second reference engaging hole, is determined relative to the positioning portion 15A, the position relative to the plate pad 20 is determined by the second engaging hole 21A, which is the second reference engaging hole. When the cushioning material 30A, which determines the size of the pad 20A, comes into contact with the restraining surface of the positioning portion 15A, the plate pad 20 and the pallet 10 are brought into a predetermined relative position. Therefore, the plate pad 20, the pallet 10, and the cushioning materials 30A to 30D can be set to predetermined relative positions.

<Third modification example>
In the above-described embodiment, the cross-sectional shape of the first engaging convex portions 33A to 33D is rectangular, but the cross-sectional shape is not limited to a rectangle. In the third modification, the cross-sectional shape of the first engaging convex portions 33A to 33D is circular.

FIG. 6 is a plan view of the plate pad in the third modification. With reference to FIG. 6, as compared with the plan view shown in FIG. 3, the first engaging hole 23A is changed to the circular first engaging hole 26A, and the first engaging holes 23B to 23D are elliptical. The shape has been changed to the first engaging holes 26B to 26D.

<Fourth modification>
The first engaging convex portions 33A to 33D may also serve as the second engaging convex portions 31A to 31D. In this case, each of the cushioning materials 30A to 30D has only the first engaging convex portions 33A to 33D, and the second engaging convex portions 31A to 31D are unnecessary.

FIG. 7 is a plan view of the plate pad in the fourth modification. With reference to FIG. 7, the plate pad 20A in the fourth modification has four engaging holes 27A to 27D corresponding to each of the four cushioning materials 30A to 30D. Of the four engaging holes 27A to 27D, the engaging hole 27A is the reference engaging hole. The relative position of the reference engaging hole with respect to the pallet 10 is predetermined. Since the engaging hole 27A, which is the reference engaging hole, is formed in the plate pad 20A, the engaging hole 27A, which is the reference engaging hole, is in a predetermined relative position with the pallet 10, and the plate pad 20A and the engaging hole 27A are in a predetermined position. The relative position with the pallet 10 is determined. Therefore, the reference engaging hole is prevented so that the plate pad 20A does not protrude from the pallet 10 in a state where the first engaging hole 27A, which is the reference engaging hole, is in a predetermined relative position with the first positioning portion 15A. The position of the engaging hole 27A in the plate pad 20A is determined.

The plate pad 20A is formed with slits 28B to 28D extending from the peripheral edges of the engagement holes 27B to 27D other than the engagement holes 27A which are reference engagement holes. The slits 28B are formed in the plate pad 20A so as to extend from five positions on the peripheral edge of the engaging hole 27B to the side opposite to the second positioning portion 15B corresponding to the engaging hole 27B. The slits 28C are formed in the plate pad 20A so as to extend from five positions on the peripheral edge of the engaging hole 27C to the side opposite to the third positioning portion 15C corresponding to the engaging hole 27C. The slits 28D are formed in the plate pad 20A so as to extend from five positions on the peripheral edge of the engaging hole 27D to the side opposite to the fourth positioning portion 15D corresponding to the engaging hole 27D. The number of slits 28B to 28D is not limited to five, and may be one or more.

The plate pad 20A is placed on the pallet 10, and the cushioning material 30A is assembled into the engagement hole 27A which is the reference engagement hole. In this case, the first engaging convex portion 33A of the cushioning material 30A is inserted into the engaging hole 27A. At this stage, the relative positions of the cushioning material 30A and the plate pad 20A and the relative positions of the pallet 10 and the plate pad 20A are not determined.

Next, the cushioning material 30C is assembled into the engaging hole 27C located diagonally to the engaging hole 27A. When the engaging convex portion 33C is pushed into the engaging hole 27C, the engaging convex portion 33C comes into contact with the second side surface 16B and the fourth side surface 17B of the third positioning portion 15C, and the engaging convex portion 33C engages the plate pad 20A. At the joint hole 27C, a pushing force acts from the third positioning portion 15C toward the engagement hole 27C. As a result, the plate pad 20A moves in the direction from the third positioning portion 15C toward the engaging hole 27C.

On the other hand, since the first engaging convex portion 33A of the cushioning material 30A penetrates the engaging hole 27A, the plate pad 20A is positioned third until the engaging hole 27A abuts on the first engaging convex portion 33A. When moving from the portion 15C toward the engaging hole 27C, the engaging convex portion 33A comes into contact with the first side surface 16A and the third side surface 17A of the first positioning portion 15A, so that the cushioning material 30A and the pallet 10 are relative to each other. The position is fixed. Further, the movement of the plate pad 20A is restricted by the engagement hole 27A coming into contact with the first engaging convex portion 33A.

After the movement of the plate pad 20A is restricted, the slit 28C is deformed and the engaging convex portion 31C is inserted into the engaging hole 27C. Thereby, the relative position between the cushioning material 30C and the pallet 10 is determined. In this state, the restoring force of the slit 28C causes the engaging convex portion 31C of the cushioning material 30C to receive a force in the direction from the slit 28C toward the engaging hole 27C, and as a reaction force thereof, the engaging convex portion 31C of the cushioning material 30A. 33A receives a force in the direction from the slit 28C toward the engaging convex portion 33A. Therefore, the force of the engaging convex portion 33C of the cushioning material 30C toward the third positioning portion 15C and the force of the engaging convex portion 33A of the cushioning material 30A toward the first positioning portion 15A are balanced.

Next, one of the cushioning materials 30B and 30D is assembled in order. For example, when the engaging convex portion 33B of the cushioning material 30B is pushed into the engaging hole 27B, the relative position between the plate pad 20A and the pallet 10 is determined, so that the engaging convex portion 33B is the second positioning portion 15B. The slit 28B is deformed by abutting on the second side surface 16B and the third side surface 17A, and the engaging convex portion 33B is inserted into the engaging hole 27B. Thereby, the relative position between the cushioning material 30B and the pallet 10 is determined. In this state, the restoring force of the slit 28B causes the engaging convex portion 33B of the cushioning material 30B to receive a force in the direction from the slit 28B toward the second positioning portion 15B.

Finally, the engaging protrusion 33D of the cushioning material 30D is inserted into the engaging hole 27D. When the engaging convex portion 33D is pushed into the engaging hole 27D, the relative positions of the plate pad 20A and the pallet 10 are determined, so that the engaging convex portion 33D is the first side surface 16A and the fourth side surface 16A of the fourth positioning portion 15D. Upon contact with the side surface 17B, the slit 28D is deformed and the engaging convex portion 33D is inserted into the engaging hole 27D. Thereby, the relative position between the cushioning material 30D and the pallet 10 is determined. In this state, the restoring force of the slit 28D causes the engaging convex portion 33D of the cushioning material 30D to receive a force in the direction from the slit 28D toward the fourth positioning portion 15D.

In the fourth modification, the packing device in the modification is such that the cushioning materials 30A to 30D are rotatable with respect to the plate pad 20A, but the same effect as that of the packing device 1 in the above-described embodiment is obtained. Can be done.
