FIG. 6 is a plan view of a top pad provided in the packing device 1 according to the first embodiment. FIG. 7 is a perspective view showing the packing device 1 according to the first embodiment. In principle, in the following description, the directions of each member are specified assuming that the packing device 1 is placed on a horizontal surface.

The packaging device 1 of this embodiment shown in these figures is used to pack a product 90. The product 90 may be, for example, an electrical appliance or other product. The product 90 may be, for example, a compressor used in an air conditioner. In this disclosure, it goes without saying that the product 90 to be packed is not limited to a compressor, and may be any product. Furthermore, there is no particular limit to the number of products 90 packed by one packaging device 1.

In the illustrated example, multiple products 90 are collectively packed in a state of being stacked in multiple layers on one pallet 11. An example of the procedure for packing the products 90 using the packing device 1 will be described below. As shown in FIG. 4, first, a bottom pad 14 is placed on the pallet 11. In the illustrated example, multiple products 90 forming the first layer are placed on one bottom pad 14. The bottom pad 14 may be formed with multiple recesses into which the lower parts of the multiple products 90 fit.

A first tier top pad 15 is placed on top of the first tier of multiple products 90 placed on the bottom pad 14 on the pallet 11. Each of the first tier of multiple products 90 is sandwiched between the first tier bottom pad 14 and the first tier top pad 15.

The second tier bottom pad 14 is placed on the first tier top pad 15. A number of products 90 forming the second tier are placed on the second tier bottom pad 14. The second tier top pad 15 is placed on the number of products 90 in the second tier. Each of the products 90 in the second tier is sandwiched between the second tier bottom pad 14 and the second tier top pad 15.

A plywood board 18 is placed on top of the second tier top pad 15.

As shown in FIG. 1, the side sleeves 13 are placed on the top surface of the pallet 11 so as to cover from the outside the bottom pad 14, the product 90, the top pad 15, etc., which are stacked on the pallet 11. The side sleeves 13 may be made of paper, for example.

In the illustrated example, the second tier of products 90 is the top tier. A top cap 16 is placed on top of the top pad 15 and plywood 18 of the second tier, which is the top tier. Next, as shown in FIG. 7, the pallet 11 and the top cap 16 are fastened together with a band 12. The band 12 may be, for example, a polypropylene band.

As shown in FIG. 6, the top pad 15 of the packaging device 1 includes a first cushioning material 2 and a second cushioning material 3. The first cushioning material 2 has a connecting protrusion 6. The second cushioning material 3 has a connecting recess 7. The connecting protrusion 6 of the first cushioning material 2 fits into the connecting recess 7 of the second cushioning material 3, thereby allowing the first cushioning material 2 and the second cushioning material 3 to be connected.

The connecting protrusion 6 can be rotated between a first rotation position and a second rotation position. The first rotation position of the connecting protrusion 6 is a rotation position in which the connecting protrusion 6 does not fit into the connecting recess 7. The state in which the connecting protrusion 6 is in the first rotation position is shown in FIG. 3.

The second rotational position of the connecting protrusion 6 is a position where the connecting protrusion 6 of the first cushioning material 2 fits into the connecting recess 7 of the second cushioning material 3. For example, the position of the connecting protrusion 6 of the first cushioning material 2 in FIG. 6 corresponds to the second rotational position. When the connecting protrusion 6 of the first cushioning material 2 fits into the connecting recess 7 of the second cushioning material 3, the first cushioning material 2 is connected to the second cushioning material 3 by the frictional force between the surface of the connecting protrusion 6 and the surface of the connecting recess 7.

In this embodiment, since the first cushioning material 2 and the second cushioning material 3 can be separated, the labor required for attaching the first cushioning material 2 and the second cushioning material 3 or removing the first cushioning material 2 and the second cushioning material 3 can be reduced. In addition, the first cushioning material 2 can be connected to the second cushioning material 3 or disconnected from the first cushioning material 2 by rotating the connecting protrusion 6 between the first rotation position and the second rotation position. This makes it possible to more reliably reduce the labor required for the work.

Furthermore, in this embodiment, when horizontal or vertical vibrations occur during handling of goods in logistics or during truck transport, the connecting portion between the first cushioning material 2 and the second cushioning material 3 can disperse and absorb the vibrations. This makes it possible to more reliably protect the product 90 from horizontal or vertical vibrations.

As shown in FIG. 3, the first cushioning material 2 has a plate-shaped base portion 8 that is aligned along a horizontal plane. The connecting protrusion 6 protrudes from the edge of the base portion 8. The connecting recess 7 has a shape that recesses inward from the edge of the base portion 8. In other words, the connecting recess 7 recesses toward the inside of the base portion 8.

When the connecting protrusion 6 is in the first rotation position, the connecting protrusion 6 protrudes upward perpendicular to the surface of the base portion 8. When the connecting protrusion 6 is in the second rotation position, the connecting protrusion 6 protrudes in a direction parallel to the surface of the base portion 8. In the illustrated example, the angle between the first rotation position of the connecting protrusion 6 and the second rotation position of the connecting protrusion 6 is 90 degrees. In this way, if the angle between the first rotation position and the second rotation position is within 90 degrees, the labor required for the work of connecting the first cushioning material 2 to the second cushioning material 3 or separating the first cushioning material 2 and the second cushioning material 3 can be more reliably reduced.

The first cushioning material 2 may be prepared so that the connecting protrusion 6 of the first cushioning material 2 protrudes upward from the base portion 8 before being connected to the second cushioning material 3. In this way, when the assembly worker fits the connecting protrusion 6 of the first cushioning material 2 into the connecting recess 7 of the second cushioning material 3, the worker does not have to bend the connecting protrusion 6 upward once. This improves workability.

As shown in FIG. 6, the top pad 15 in this embodiment includes a first cushioning material 2, a second cushioning material 3, a third cushioning material 4, and a fourth cushioning material 5. The first cushioning material 2 is connected to the second cushioning material 3, the second cushioning material 3 is connected to the third cushioning material 4, and the third cushioning material 4 is connected to the fourth cushioning material 5, thereby forming one top pad 15. The first cushioning material 2, the second cushioning material 3, the third cushioning material 4, and the fourth cushioning material 5 may have the same or similar shapes. If the first cushioning material 2, the second cushioning material 3, the third cushioning material 4, and the fourth cushioning material 5 have the same or similar shapes, the number of types of parts can be reduced, thereby reducing costs.

Each of the first cushioning material 2, the second cushioning material 3, the third cushioning material 4, and the fourth cushioning material 5 may be a paper-based molded product, generally known as a pulp mold, or may be made of cardboard.

5, the first cushioning material 2 has a side contact portion 9 that contacts the side of the product 90 and an upper contact portion 10 that contacts the upper surface of the product 90. Similarly, each of the third cushioning material 4, the third cushioning material 4, and the fourth cushioning material 5 may also have a side contact portion 9 that contacts the side of the product 90 and an upper contact portion 10 that contacts the upper surface of the product 90. In the illustrated example, by providing the side contact portion 9 and the upper contact portion 10, it becomes possible to more reliably protect the product 90 from horizontal or vertical vibrations when horizontal or vertical vibrations act during handling of goods in logistics or during truck transport.

In the example of FIG. 5, the side contact portion 9 is cylindrical or annular and protrudes upward from the base portion 8. The top contact portion 10 protrudes from the inner periphery of the upper end of the side contact portion 9 toward the inner periphery. In the example of FIG. 5, the first cushioning material 2 further includes a top portion 17 that protrudes upward from the inner periphery of the top contact portion 10. The top surface of the top portion 17 is closed. In the example of FIG. 5, a stepped portion is formed by the side contact portion 9, the top contact portion 10, and the top portion 17.

In this embodiment, the shape of each of the connecting protrusions 6 and the connecting recesses 7 is rectangular. This makes it possible to achieve the above-mentioned effects using the connecting protrusions 6 and the connecting recesses 7 that are simply shaped.

In the example shown in FIG. 6, the second cushioning material 3 has a connecting protrusion 6. The third cushioning material 4 has a connecting recess 7 that can fit into the connecting protrusion 6 of the second cushioning material 3. The second cushioning material 3 and the third cushioning material 4 can be connected by the connecting protrusion 6 of the second cushioning material 3 fitting into the connecting recess 7 of the third cushioning material 4. The connecting protrusion 6 of the second cushioning material 3 can be rotated between a first rotation position where it does not fit into the connecting recess 7 of the third cushioning material 4, and a second rotation position where it fits into the connecting recess 7 of the third cushioning material 4.

In the example shown in FIG. 6, the third cushioning material 4 has a connecting protrusion 6. The fourth cushioning material 5 has a connecting recess 7 that can fit with the connecting protrusion 6 of the third cushioning material 4. The third cushioning material 4 and the fourth cushioning material 5 can be connected by the connecting protrusion 6 of the third cushioning material 4 fitting into the connecting recess 7 of the fourth cushioning material 5. The connecting protrusion 6 of the third cushioning material 4 can be rotated between a first rotation position where it does not fit into the connecting recess 7 of the fourth cushioning material 5, and a second rotation position where it fits into the connecting recess 7 of the fourth cushioning material 5.

In the illustrated example, a single first cushioning material 2 is provided with multiple connecting protrusions 6, and a single second cushioning material 3 is provided with multiple connecting recesses 7. This allows the two to be connected more reliably. Not limited to the illustrated example, in the present disclosure, a single first cushioning material 2 may be provided with only one connecting protrusion 6, and a single second cushioning material 3 may be provided with only one connecting recess 7.

In the illustrated example, multiple products 90 are in contact with one first cushioning material 2. This makes it possible to make the number of first cushioning materials 2 smaller than the number of products 90. Also, multiple products 90 are in contact with one second cushioning material 3. This makes it possible to make the number of second cushioning materials 3 smaller than the number of products 90. Not limited to the illustrated example, in the present disclosure, the number of products 90 in contact with one first cushioning material 2 may be only one, and the number of products 90 in contact with one second cushioning material 3 may be only one.

In the illustrated example, one top pad 15 is divided into four cushioning materials: a first cushioning material 2, a second cushioning material 3, a third cushioning material 4, and a fourth cushioning material 5. In the present disclosure, the present disclosure is not limited to the illustrated example, and one top pad 15 may be divided into two, the first cushioning material 2 and the second cushioning material 3. Also, one top pad 15 may be divided into three cushioning materials: the first cushioning material 2, the second cushioning material 3, and the third cushioning material 4. Alternatively, one top pad 15 may be divided into five or six or more cushioning materials.

Figure 7 shows the state where packaging by the packaging device 1 is completed. When unpacking from the state shown in Figure 7, first, the top cap 16 is removed, and then the top pad 15 is removed from the product 90. In this embodiment, one top pad 15 is divided into multiple cushioning materials, so that the top pad 15 can be easily removed from the product 90. In addition, when horizontal or vertical stress is applied to the product 90 during handling of goods in logistics or transportation by truck, the adjacent cushioning materials are connected to each other due to the uneven shape of the fitting part of the connecting convex part 6 and the connecting concave part 7 of the top pad 15, so that the stress acting on the product 90 is dispersed. Therefore, the product 90 is less likely to tilt, and the holding power against stress is improved. In this way, with this embodiment, it is possible to provide a packaging device 1 that improves workability and quality during logistics.

As shown in FIG. 3, the first cushioning material 2 may be formed so that the connecting protrusion 6 of the first cushioning material 2 protrudes upward from the base portion 8 in the first cushioning material 2 before being connected to the second cushioning material 3. That is, the first cushioning material 2 may be formed so that the connecting protrusion 6 is in the first rotation position. When the first cushioning material 2 is arranged adjacent to the second cushioning material 3, the connecting protrusion 6 of the first cushioning material 2 is adjacent to the connecting recess 7 of the second cushioning material 3. Then, when the connecting protrusion 6 of the first cushioning material 2 is rotated so as to tilt the connecting protrusion 6, the connecting protrusion 6 of the first cushioning material 2 is inserted into the connecting recess 7 of the second cushioning material 3 and fitted. In this way, with this embodiment, it is possible to fit the connecting protrusion 6 of the first cushioning material 2 into the connecting recess 7 of the second cushioning material 3 with a simple operation.
