Japanese Patent Application Publication No. 2017-149472

By the way, due to the recent increase in the size of glass plates to be transported, the following problems have arisen that need to be solved when storing pallets in containers.

That is, when storing pallets in containers, a forklift or the like is used to transport the pallets. However, as the glass plates included in the laminates have become larger, the pallets on which the laminates are loaded have also become larger, and there are increasing cases where there is not enough space inside the container for the size of the pallet. ing. Therefore, during the storage process, precise work is required to avoid contact between the pallet (laminates loaded on the pallet) being transported by a forklift or the like and the inner surface of the container, resulting in a large storage burden. was there.

The present invention was developed in view of the above circumstances, and when storing a pallet loaded with laminates including glass plates in a container, even when there is not enough space in the container for the size of the pallet, The technical challenge is to reduce the burden of containment.

A method for manufacturing a package for solving the above problem is a method for manufacturing a package including a pallet and a container by storing a pallet loaded with a laminate including glass plates in a container. , including a transfer step of transferring the pallet within the container, and the transfer step is characterized in that the pallet is transferred by a first transfer device interposed between the bottom surface of the container and the base of the pallet.

In this manufacturing method, in the transfer step of transferring the pallet within the container, the pallet is transferred by a first transfer device interposed between the bottom surface of the container and the base of the pallet. By using a transport device like this, even if there is not enough space inside the container for the size of the pallet, it is possible to avoid the situation where a gap is formed between the pallet and the inner surface of the container during the transport process. can be stably secured. Therefore, contact between the pallet and the inner surface of the container can be avoided, and the pallet can be smoothly accommodated in the container. As a result, the burden of accommodation can be reduced.

In the above method, it is preferable to use a device provided with a rolling member as the first conveyance device in the transfer step.

In this way, the pallet can be transported using the rolling motion of the rolling member. This makes it possible to easily transport the pallet.

In the above method, in the transfer step, it is preferable to use a roller conveyor installed at the bottom of the container as the first transfer device.

In this way, it is not necessary to provide rolling members for all the pallets, and a plurality of pallets can be transported by a common roller conveyor. Therefore, the equipment cost for transporting pallets within the container can be suppressed. Furthermore, even heavy pallets loaded with large glass plates can be transported.

In the above method, when the width direction of the container is defined as the direction perpendicular to the pallet transfer direction when viewed from a plan view of the bottom surface inside the container, in the transfer process, the width direction of the container on the roller conveyor is Preferably, the movement is restricted by a restriction member.

In this way, it is possible to reliably eliminate the possibility that the pallet being transported by the roller conveyor will come into contact with the side surface inside the container due to the positional shift of the conveyor. Therefore, the pallet can be transported efficiently, and damage to the container, pallet, glass plate, etc. due to contact can be prevented.

In the above method, the transfer step includes using a plurality of roller conveyors lined up in the pallet transfer direction, and also includes a placing step for placing the pallet that has been transferred to the target position in the container by the transfer step at the target position. However, there is a lifting process in which at least a part of the base part is raised from a plurality of roller conveyors existing under the base of the pallet, and a plurality of roller conveyors with at least a part of the base part raised. It is preferable to include a removing step of removing at least one of the above, and a lowering step of lowering the elevated portion of the base after the removing step.

In this way, in the removal process, at least one of the plurality of roller conveyors below the base is removed, so the pallet after the lowering process will not move unnecessarily from the target position, or the pallet will not move unnecessarily from the target position. It becomes difficult to do. This makes it difficult for the pallet to shift its position within the container during transportation of the package.

In the above method, after the removal step and before the lowering step, a pedestal is installed in the space formed by the removal of the roller conveyor to be interposed between the bottom of the container and the base of the pallet. It is preferable to do so.

In this way, it becomes possible to reduce the burden of carrying out the pallet from the container after transporting the package. The reason for this is as follows. In order to reduce the burden of transporting the pallet, it is advantageous to interpose a roller conveyor between the bottom inside the container and the base of the pallet. If a pedestal is interposed between the bottom of the container and the base of the pallet in the installation process, a gap can be formed between the bottom of the container and the base of the pallet. In this case, when the roller conveyor is interposed in place of the pedestal again when the pallet is carried out, it becomes easy to raise the base portion of the pallet. Therefore, the burden of carrying out the pallet from the container can be reduced.

The above method includes a carrying-in step of carrying a pallet into the container from outside the container, and the carrying-in step includes a preparation step of arranging a second carrying device outside the container in series with a first carrying device inside the container; It is preferable to include a mounting step of mounting the pallet on the transport device and a transfer step of transferring the pallet from the second transport device onto the first transport device.

In this way, by arranging the second conveyance device outside the container in series with the first conveyance device inside the container, it is possible to easily carry the pallet into the container from outside the container.

Further, according to the package described below, it is possible to obtain the same functions and effects as some of the methods for manufacturing the package described above.

The package includes a pallet loaded with a laminate including glass plates and a container housing the pallet, and a roller is installed between the bottom of the container and the base of the pallet. At least one of the conveyor and the pedestal is interposed as an intervening member, and the intervening member is arranged so as to extend in the direction in which the pallet is transported within the container.

In the above package, when the width direction of the container is defined as the direction perpendicular to the pallet transfer direction when viewed from the bottom of the container in a plan view, movement in the width direction of the container in the intervening member is restricted. Preferably, it is regulated by a member.

In this way, it is possible to obtain the same functions and effects as some of the methods for manufacturing the package described above.

According to the present invention, when storing a pallet loaded with laminates including glass plates in a container, even if there is not enough space in the container for the size of the pallet, the burden of storing the pallet is reduced. It becomes possible to make it lighter.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A package and a method of manufacturing the package according to an embodiment of the present invention will be described below with reference to the accompanying drawings. Here, the X direction, Y direction, and Z direction shown in each drawing referred to in the description of the embodiments are directions orthogonal to each other. The X direction and the Y direction are horizontal directions, and the Z direction is a vertical direction.

First, the structure of the package will be explained.

As shown in FIGS. 1 to 3, the package 1 includes a pallet 4 on which a laminate 3 including glass plates 2 is loaded, and a container 5 that accommodates the pallet 4. In this package 1, a roller conveyor 6 (colocon) and a pedestal 7 are interposed between the bottom surface 5a of the container 5 and the base portion 4a of the pallet 4 as intervening members.

The container 5 has a rectangular parallelepiped shape that is elongated in the X direction. Note that the X direction is a transfer direction when the pallet 4 is transferred within the container 5. The container 5 has a main body 5x for accommodating the pallet 4, and a door 5y for opening and closing an opening 5xa formed at one end of the main body 5x in the X direction. Both the cross section of the main body portion 5x (the cross section perpendicular to the X direction) and the opening 5xa have a substantially rectangular shape.

The length of the space S formed in the main body portion 5x along the X direction is longer than the length along the Y direction and the Z direction. Note that the Y direction and the Z direction are the width direction and height direction of the container 5, respectively. The main body portion 5x has, as its inner surface, a bottom surface 5a, a top surface 5b, one side surface 5c, the other side surface 5d, and a rear surface 5e. The door portion 5y allows the pallet 4 to be carried in and out of the container 5 along the X direction by keeping the opening 5xa open. A convex portion is formed on the top surface 5b of the opening 5xa. For example, in the cross section of the main body portion 5x, the height (distance from the bottom surface 5a to the top surface 5b) is about 2660 mm, and the width (distance from one side surface 5c to the other side surface 5d) is about 2340 mm. Further, in the opening 5xa, the height (distance from the bottom surface 5a to the convex portion) is approximately 2580 mm, and the width (distance from one side surface 5c to the other side surface 5d) is approximately 2340 mm.

The laminate 3 is made by stacking a plurality of rectangular glass plates 2 with a protective sheet (not shown) interposed between them. The laminate 3 is stacked on a pallet 4 in an inclined position with respect to a horizontal plane (XY plane). The gap between the laminate 3 and the top surface 5b is, for example, 100 mm to 160 mm.

Each of the dimensions of the vertical side 2a (side extending vertically along the slope) and the horizontal side 2b (side extending in the X direction) of the glass plate 2 is smaller than the Y direction dimension at the opening 5xa of the container 5. is also getting bigger. That is, the glass plate 2 has a size that cannot be carried into the container 5 when it is placed horizontally. The dimensions of the vertical side 2a x the horizontal side 2b of the glass plate 2 are 2200 mm x 2500 mm or more. The dimensions of the vertical side 2a x the horizontal side 2b are preferably 2400 mm x 2800 mm or more, more preferably 2800 mm x 3100 mm or more, and most preferably 2900 mm x 3300 mm or more. In this embodiment, the glass plate 2 has a G10.5 size. The thickness of the glass plate 2 is, for example, 0.2 mm to 2 mm.

The vertical side 2a of the glass plate 2 extends so as to follow a rectangular diagonal line formed by a cross section (a cross section perpendicular to the X direction) of the main body portion 5x of the container 5. Here, the angle between the vertical side 2a of the glass plate 2 and the diagonal line is preferably 10° or less, more preferably 5° or less.

The protective sheet is, for example, a glass interleaving paper or a foamed resin sheet, and has a size that is one size larger than the glass plate 2. Thereby, the protective sheet protrudes from the vertical side 2a and horizontal side 2b of the glass plate 2, respectively.

Two pallets 4 are housed in a container 5. Of course, only one pallet 4 or three or more pallets 4 may be accommodated in the container 5 depending on the size of the space S formed in the main body 5x of the container 5. Each of the two pallets 4 includes a base portion 4a and a loading portion 4b for loading the laminate 3. Each pallet 4 is fixed to the main body 5x of the container 5 via a jig or the like (not shown).

The base portion 4a has a total of four side surfaces 4s, two side surfaces 4s parallel to the X direction and two side surfaces 4s parallel to the Y direction. Of the two side surfaces 4s parallel to the X direction, the side surface 4s located on the back side of the stacked body 3 has a hole H into which a fork of a forklift is inserted (not shown). In addition, a hole H into which a fork of a forklift is inserted is formed in each of the two side surfaces 4s parallel to the Y direction. Note that a hole H into which a fork of a forklift is inserted may be formed in both of the two side surfaces 4s parallel to the X direction. The gap between the side surface 4s parallel to the X direction and the side surfaces 5c and 5d inside the container 5 is, for example, 10 to 30 mm. A recess R into which the roller conveyor 6 and the pedestal 7 fit, respectively, is formed in the bottom surface 4z of the base portion 4a. The recesses R are formed at two locations spaced apart in the Y direction. Of course, the recesses R may be formed at three or more locations. Each recess R is formed in a groove shape and extends along the X direction. Note that the recess R may not be formed on the bottom surface 4z of the base portion 4a.

The stacking section 4b is provided above the base section 4a, and supports the stacked body 3 in an inclined position from the back side. The loading section 4b is combined with the base section 4a via a frame 8 that extends vertically, horizontally, and diagonally.

Between the rear surface 5e of the container 5 and the first pallet 4, between the first and second pallets 4, and between the second pallet 4 and the door 5y of the container 5. , stoppers 9 are arranged to restrict movement of the pallet 4 in the X direction. The stopper 9 has a regulating surface that regulates the movement of the pallet 4 by coming into contact with the side surface 4s of the pallet 4 parallel to the Y direction. Further, the stopper 9 has a support surface that supports the pallet 4 by coming into contact with the bottom surface of the pallet 4. In this embodiment, the stopper 9 is made of wood and can be fixed to the bottom surface 5a inside the container 5 using nails, screws, or the like. Of course, the stopper 9 may be made of other than wood.

The roller conveyor 6 and the pedestal 7 are each arranged at two locations with an interval in the Y direction. Of course, the roller conveyor 6 and the pedestal 7 may be arranged at three or more locations. Alternatively, the roller conveyor 6 and the pedestal 7 may be arranged in a row without any interval.

Here, in the following description, a distinction will be made between the roller conveyor 6 and pedestal 7 placed on one side of the two locations, and the roller conveyor 6 and pedestal 7 placed on the other side, as necessary. When distinguishing, the roller conveyor 6 and pedestal 7 placed on one side of the two locations are respectively referred to as one side conveyor 6 and one side pedestal 7, and the roller conveyor 6 and pedestal placed on the other side are referred to as one side conveyor 6 and one side pedestal 7, respectively. 7 are respectively written as the other side conveyor 6 and the other side pedestal 7.

Each of the roller conveyor 6 and the pedestal 7 is elongated and arranged so that their longitudinal directions extend in the X direction. Below the base portion 4a of one pallet 4, the pedestal 7 is arranged closer to the opening 5xa of the container 5 than the roller conveyor 6. Movement of each of the roller conveyor 6 and the pedestal 7 in the Y direction is regulated by a plate member 10 serving as a regulating member disposed on the bottom surface 5a inside the container 5. In this embodiment, the plate member 10 is made of wood and can be fixed to the bottom surface 5a inside the container 5 using nails, screws, or the like. Of course, the plate member 10 may be made of materials other than wood.

The plate member 10 is arranged between (A) one side 5c in the container 5 and one side conveyor 6 (one side pedestal 7), (B) one side conveyor 6 (one side pedestal 7) and the other side conveyor 6 (the other side pedestal 7) and between the other side surface 5d in the container 5 (C) and the other side conveyor 6 (the other side pedestal 7), respectively, without any gaps. The top surfaces of the plate members 10 arranged in each of (A) to (C) are located below the bottom surface 4z of the pallet 4 to avoid contact with the pallet 4.

Here, in this embodiment, the plate member 10 is used as the regulating member, but the present invention is not limited to this. The regulating member may be any member that can regulate the movement of the roller conveyor 6 and the pedestal 7 in the Y direction while avoiding contact with the pallet 4, and may be a frame, for example. Alternatively, the plate member 10 as a regulating member may be omitted.

As shown in FIG. 4, the pedestal 7 includes a wooden base 7a and a rubber sheet 7b fixed on the base 7a. The roller conveyor 6 includes rollers 6a. The upper surface 7s of the pedestal 7 made of the surface of the rubber sheet 7b is located at a slightly higher position than the upper end of the roller 6a. As a result, there is a height difference G between the upper surface 7s of the pedestal 7 and the upper end of the roller 6a, making it easier for the base portion 4a (recessed portion R) of the pallet 4 to come into contact with the rubber sheet 7b than with the roller 6a. . The height difference G is, for example, 1 mm to 10 mm. Note that various types of cushioning materials may be arranged in place of the rubber sheet 7b, for example, thick rubber plates, plate-shaped sponges, etc. may be arranged.

Next, a method for manufacturing the above package 1 will be explained.

In this manufacturing method, a pallet 4 loaded with a laminate 3 including a glass plate 2 is housed in a container 5, and a package 1 including the pallet 4 and the container 5 is manufactured. This manufacturing method is particularly effective when the size of the space S in the container 5 is limited relative to the size of the pallet 4.

In this manufacturing method, when storing one pallet 4 in the container 5, the pallet 4 is transported into the container 5 from outside the container 5 (see FIGS. 5 to 9), and the pallet 4 is transported inside the container 5. A transfer process (FIG. 10) for transferring and a placing process (FIGS. 11 to 14) for placing the pallet 4, which has been transferred to the target position in the container 5 by the transfer process, at the target position are executed.

The carrying-in process includes a preparation process, a mounting process, and a transfer process.

As shown in FIG. 5, in the preparation process, a second conveyance device is placed outside the container 5 in series with the first conveyance device inside the container 5 with the door 5y of the container 5 opened and the opening 5xa open. do. In this embodiment, a roller conveyor 6 (roller conveyor) including rollers 6a as rolling members is used as the first conveyance device. Moreover, the roller conveyor 11 (roller conveyor) is similarly used as the second conveyance device. Note that both roller conveyors 6 and 11 have the same configuration. Moreover, both roller conveyors 6 and 11 do not have a driving part.

More specifically, in the preparation process, the following operations may be performed in order.

First, as shown in FIG. 6, the stopper 9 is placed along the rear surface 5e inside the container 5. When the arrangement of the stopper 9 is completed, next, a plurality of plate members 10 are arranged and installed in the X direction along each of the one side surface 5c and the other side surface 5d inside the container 5, in line with the stopper 9. Each of the plate members 10 along one side surface 5c and each plate member 10 along the other side surface 5d are installed without any gaps with respect to the one side surface 5c and the other side surface 5d, respectively. Further, each plate member 10 may be partially or entirely fixed to the bottom surface 5a inside the container 5, or may not be fixed.

Next, as shown in FIG. 7, a plurality of roller conveyors 6 are installed inside each of the plurality of plate members 10 along one side 5c and the plurality of plate members 10 along the other side 5d. Install them side by side in the X direction. Each roller conveyor 6 is installed with no gap between adjacent plate members 10. Thereby, on the bottom surface 5a inside the container 5, a plurality of roller conveyors 6 lined up in the X direction are set as one row, and two rows of roller conveyors 6 are installed at intervals in the Y direction. Note that the distance between the first row and the second row in the Y direction is equal to the distance between the two recesses R formed on the bottom surface 4z of the pallet 4. In this way, the dimension in the Y direction of each plate member 10 is adjusted so that the distance between the first and second rows and the distance between the two recesses R are equal.

Next, as shown in FIG. 8, a plurality of plate members 10 are arranged and installed in the X direction between the roller conveyor 6 belonging to the first row and the roller conveyor 6 belonging to the second row. Each plate member 10 is installed with no gap between the two adjacent roller conveyors 6, 6. This restricts the movement of each roller conveyor 6 belonging to the first row and each roller conveyor 6 belonging to the second row in the Y direction.

Finally, a plurality of roller conveyors 11 are arranged in the X direction outside the container 5 in series with the plurality of roller conveyors 6 inside the container 5. Of course, the plurality of roller conveyors 11 are also installed in two rows at intervals in the Y direction. Note that the movement of each roller conveyor 11 belonging to the first row and each roller conveyor 11 belonging to the second row in the Y direction may or may not be restricted. In addition, when regulating, it is preferable to regulate at least the roller conveyor 11 near the opening 5xa of the container 5. The preparation process is thus completed.

Here, in this embodiment, between the roller conveyors 6, 6 adjacent in the X direction, between the roller conveyors 11, 11 adjacent in the X direction, and between the roller conveyors 6 and 11 adjacent in the X direction. Although no gap is provided between them, it is of course possible to provide a gap.

After the preparation process is completed, a mounting process is performed next. In the mounting process, the pallet 4 is mounted on a plurality of roller conveyors 11 outside the container 5, as shown by the two-dot chain line in FIG. At this time, the pallet 4 is placed so that the roller conveyor 11 belonging to the first row and the roller conveyor 11 belonging to the second row fit into the two recesses R formed on the bottom surface 4z of the pallet 4, respectively. Here, in carrying out the mounting process, for example, a forklift is used. Then, with the fork inserted into the hole H formed in the side surface 4s parallel to the X direction among the four side surfaces 4s of the pallet 4, the pallet 4 is lifted and the pallet 4 is placed onto the roller conveyor 11. will be placed. Note that the fork is preferably inserted from the back side of the laminate 3. With the above steps, the mounting process is completed.

When the mounting process is completed, a transfer process is performed next. In the transfer process, the pallet 4 is transported from the position shown by the two-dot chain line to the position shown by the solid line in FIG. 9 using the plurality of roller conveyors 6 and the plurality of roller conveyors 11. In this way, the pallet 4 is transferred from the plurality of roller conveyors 11 onto the plurality of roller conveyors 6. At this time, the position of the pallet 4 in the Y direction is regulated by both side surfaces of the recess R on the bottom surface 4z of the pallet 4 and both side surfaces of the plurality of roller conveyors 6 and 11. Here, in carrying out the transfer process, for example, a forklift is used. Then, with a fork inserted into a hole H formed in a side surface 4s parallel to the Y direction among the four side surfaces 4s of the pallet 4, the pallet 4 is pushed and conveyed without being lifted by a forklift. The transfer process is thus completed.

When the transfer process is completed as described above, and all the steps of the carry-in process are completed, the transfer process is executed next. In the transfer process, a plurality of roller conveyors 6 are used to transport the pallet 4 from the position shown by the two-dot chain line in FIG. 10 to the position shown by the solid line. At this time, the position of the pallet 4 in the Y direction is regulated by both side surfaces of the recess R of the bottom surface 4z of the pallet 4 and both side surfaces of the plurality of roller conveyors 6. Note that the position indicated by the solid line is the target position, and is the position where the side surface 4s of the pallet 4 comes into contact with the stopper 9. Here, in carrying out the transfer process, as an example, the pallet 4 is transferred on a plurality of roller conveyors 6 by pushing the pallet 4 with a forklift without lifting it in the same manner as the above-described transfer process. The transfer process is thus completed.

When the transfer process is completed, the installation process is performed next, and the installation process includes an ascending process, a removing process, and a descending process.

As shown in FIG. 11, in the lifting step, the jack 12 is used to lift the end of the base portion 4a of the pallet 4 (the end on the opening 5xa side). The height of lifting is, for example, 10 mm to 100 mm. As a result, at least a portion of the base portion 4a of the pallet 4 is lifted from the plurality of roller conveyors 6 existing under the base portion 4a. In this embodiment, the base portion 4a is mainly supported by the stopper 9 and the jack 12. There are four roller conveyors 6 under the base portion 4a (four roller conveyors are present in each of the first and second rows). With the above steps, the ascending process is completed.

Once the raising process is completed, a removing process is performed next. In the removal step, at least one of the plurality of roller conveyors 6 existing under the floating portion of the base portion 4a is pulled out and removed. In this embodiment, as shown in FIG. 12, of the four roller conveyors 6 below the base portion 4a, three on the opening 5xa side are removed. The removal process is thus completed. In addition, if it is possible to take out the roller conveyor 6 in the removal process, the base part 4a and the roller conveyor 6 will be in contact with each other without the base part 4a floating when the raising process is completed and in the removal process. Good too.

After the removal process, as shown in FIG. 13, in the space formed by the removal of the three roller conveyors 6 on the opening side, there is a space between the bottom surface 5a inside the container 5 and the base part 4a of the pallet 4. A pedestal 7 for interposition is installed. After that, a lowering step is performed. In the lowering step, by restoring the lifting of the end of the base portion 4a by the jack 12, the lifted portion of the base portion 4a is lowered, as shown in FIG. With the above steps, the lowering process is completed.

When the lowering process is completed as described above and all the steps of the installation process are completed, the pallet 4 is fixed to the main body 5x of the container 5 using a belt or the like. In this state, the position of the pallet 4 in the Y direction is regulated by both side surfaces of the recess R on the bottom surface 4z of the pallet 4 and both side surfaces of the pedestal 7 and the plurality of roller conveyors 6. Thereafter, as shown in FIG. 14, the stopper 9 is placed adjacent to the opening 5xa side of the base portion 4a of the pallet 4. After that, the above-described series of steps for storing one pallet 4 in the container 5 is executed again, and as shown in FIG. 15, the second pallet 4 is stored in the container 5. go. When the storage of the second pallet 4 is completed, the package 1 shown in FIG. 1 is manufactured.

In addition, when carrying out the pallet 4 from the container 5 after transporting the package 1, etc., the series of steps for accommodating one pallet 4 in the container 5 described above may be performed in the reverse order. . In addition, when transporting the pallet 4 within the container 5 for carrying out, a forklift is used, for example. Then, the pallet 4 is conveyed on a plurality of roller conveyors 6 by pulling the pallet 4 with the forklift without lifting it under a state in which a band or the like is stretched between the forklift and the pallet 4 to fix both.

The main functions and effects of the above manufacturing method will be explained below.

In the above manufacturing method, in the transfer step of transferring the pallet 4 within the container 5, the pallet 4 is conveyed by the roller conveyor 6. As a result, even if there is not enough space S in the container 5 for the size of the pallet 4, the inner surfaces of the pallet 4 and container 5 (bottom surface 5a, top surface 5b, one side surface 5c, A state in which a gap is formed between the other side surface 5d) can be stably ensured. Therefore, contact between the pallet 4 and the inner surface of the container 5 can be avoided, and the pallet 4 can be smoothly accommodated in the container 5. As a result, the burden of accommodation can be reduced.

Here, the package and the method for manufacturing the package according to the present invention are not limited to the configurations and aspects described in the above embodiments. For example, in the embodiment described above, the roller conveyor 6 and the roller conveyor 11 are used as the first conveyance device and the second conveyance device, respectively, but the present invention is not limited to this. As the first conveyance device and the second conveyance device, a belt conveyor, a cart on which the pallet 4 can be loaded, or the like may be used. Alternatively, wheels may be attached to the base portion 4a of the pallet 4, and the wheels may function as the first conveyance device and the second conveyance device.

Furthermore, in the embodiment described above, both roller conveyors 6 and 11 do not have a drive part, but of course they may have a drive part. In this case, the pallet 4 can be conveyed by both roller conveyors 6 and 11 without having to push the pallet 4 with a forklift or the like.

In addition, in the above embodiment, the roller conveyor 6 and the pedestal 7 are interposed between the bottom surface 5a in the container 5 and the base portion 4a of the pallet 4 after the lowering step included in the installation step. However, this is not the case. As a modification, only the pedestal 7 may be interposed between the bottom surface 5a inside the container 5 and the base portion 4a of the pallet 4.
