Hereinafter, the loading pallet concerning one embodiment of the present invention is explained in detail based on a drawing.
FIG. 1A places the stacked sheet-like objects 2 on the mounting pallet 1 of the present embodiment with the flat surface facing in the vertical direction, and is made of metal such as iron or PET (polyethylene The state fixed by the band 3 which consists of resin etc., such as a terephthalate), is shown.
In the figure, when the band 3 is wound around the to-be-packaged goods 2, the code | symbol 14 is a corner of the lower surface of the top plate 6 and the side surface of the to-be-packaged goods 2, The paper angle is an L-folded paper angle located at the corner of the. Moreover, the to-be-packaged item 2, the band 3, and the paper angle 14 are shown by the dashed-two dotted line.

  As shown in FIGS. 1A to 3, the mounting pallet 1 has a mounting portion 4 on which the object to be packed 2 is mounted, and two legs 5 attached to the lower surface of the mounting portion 4. Both are mainly made of corrugated paper 7 and 8. Concretely, as shown in FIG. 3, the corrugated board 7 which comprises other than top plate 6 of mounting part 4 mentioned later has a pair of liners 7a and a flute 7b bent in a wavelike manner between a pair of liners 7a. It is formed by pasting together. On the other hand, the corrugated board 8 constituting the top plate 6 is formed of what is called a double flute in which two flutes 7b1 and 7b2 having different step heights are bonded between three liners 7a.

The two legs 5 are, as shown in FIGS. 1B and 2A, line symmetrical with respect to a center line CL extending along the surface direction of the mounting portion 4 through the center position O of the mounting portion 4, And, they are arranged in parallel, respectively. Further, in the present embodiment, the two leg portions 5 are attached to the positions of the substantially both end portions 4 a of the mounting portion 4. In this case, below the mounting portion 4, a space between the two legs 5 is a space into which a claw (not shown) of a forklift is inserted to lift the mounting pallet 1.
In the following description, the longitudinal direction of the leg 5 is referred to as the X direction, and the direction orthogonal to the longitudinal direction of the leg 5 is referred to as the Y direction. The direction perpendicular to the surface direction is called the Z direction.

  As shown in FIG. 3, the leg portion 5 is formed by laminating a plurality of corrugated cardboard sheets 7 extending in the longitudinal direction of the leg portion 5 in the Y direction and bonding them with an adhesive. Specifically, the leg portion 5 is configured by setting the corrugated paper 7 in such a posture that the extending direction of the flutes 7b is directed to the Z direction, and bonding the opposed liners 7a of the corrugated paper 7 to each other. The extending direction of the flute 7b refers to a direction perpendicular to the direction in which the crests of the corrugated paper 7 are aligned with the crests, that is, a direction in which the flutes 7b extend without being curved.

  The lower surface of the leg 5 and both end surfaces in the longitudinal direction are covered with an adhesive tape or the like for reinforcement. Further, between the lower surface of the leg portion 5 and both end surfaces in the longitudinal direction, an inclined surface 5a is formed in order to improve the handling at the time of conveyance by the conveyor.

It may be attached closer to both end portions 4 a of the mounting portion 4 than the line CL in parallel with the center line CL.
In addition to the two legs 5, the mounting pallet 1 may have other legs, in which case the plurality of legs are line symmetrical with respect to the center line CL, respectively. It should just be arrange | positioned in parallel and attached to the lower surface of the mounting part 4. FIG. For example, when the two legs 5 illustrated are attached at the positions of the substantially both end portions 4a of the placement unit 4, the total of stacked sheet-like objects by the configuration of the placement unit 4 described later It can withstand up to about 600 kg in weight. Moreover, when it has three leg parts including the said other leg part, the said total weight can endure to about 1200 kg by the structure of the mounting part 4 mentioned later.

  As shown in FIGS. 1B and 2A to 2C, the placement unit 4 includes a top plate 6, an upper placement plate 9, a honeycomb layer 11, and a lower placement plate 10. The honeycomb layer 11 is disposed between the upper mounting plate 9 and the lower mounting plate 10 and is fixed to the upper mounting plate 9 and the lower mounting plate 10, respectively. The upper mounting plate 9 and the lower mounting plate 10 have a rectangular shape, and the sizes thereof are equal to each other. The upper mounting plate 9 and the lower mounting plate 10 have a length in the X direction slightly shorter than the length in the X direction of the legs 5, and a length in the Y direction is outside the two legs 5. It is approximately equal to the distance between the sides.

  The top plate 6 has a size larger than that of the upper placement plate 9 in accordance with the size of the item to be packaged 2. Moreover, although the top plate 6 may be bonded to the upper mounting plate 9, it is not bonded to the upper mounting plate 9 so as to be able to be changed according to the size of the packaged object 2, and simply the upper mounting plate It may be arranged on 9 and used.

The upper placement plate 9 is formed by bonding facing liners 7a of a plurality of (two in the present embodiment) corrugated paper sheets 7 so that the extending directions of the respective flutes 7b are orthogonal to each other.
Further, the lower mounting plate 10 is also formed by bonding facing liners 7a of a plurality of (two in the present embodiment) corrugated paper sheets 7 so that the extending directions of the respective flutes 7b are orthogonal to each other. There is.

It is pasted together. However, the upper and lower mounting plates of the present invention are not limited to two stages, and any corrugated paperboard 7 may be attached as long as the extending directions of the flutes 7b intersect.

  In addition, the honeycomb layer 11 extends the elongated spacer pieces 12 extending in the Y direction (that is, the direction orthogonal to the longitudinal direction of the legs 5 in the surface direction of the mounting portion 4) A plurality of (six in this embodiment) are arranged at predetermined intervals in the longitudinal direction. The length in the Y direction of each spacer piece 12 is designed to be substantially equal to the length in the Y direction of the upper mounting plate 9 and the lower mounting plate 10. Further, the predetermined distance between the adjacent spacer pieces 12 is set so that the band 3 is inserted into the insertion space s formed by the adjacent spacer pieces 12 and the upper and lower mounting plates 9 and 10. It is designed to be larger than the width.

  Further, in each spacer piece 12, a plurality of (in this embodiment, ten sheets) corrugated cardboard sheets 7 are bonded, and the extending direction of each flute 7b is perpendicular to the Z direction, ie, the surface direction of the mounting portion 4. Each is formed to be The plurality of spacer pieces 12 are formed by pasting a predetermined number of corrugated cardboard sheets 7 and then cutting them at a predetermined height along the direction in which the flutes 7 b are arranged.

  In the present embodiment, the upper mounting plate 9 and the honeycomb layer 11, the honeycomb layer 11 and the lower mounting plate 10, and the lower mounting plate 10 and the leg portion 5 are bonded using an adhesive wax. Not only this but each should just be stuck.

  The top 6 is formed by the double flute as described above. The top plate 6 is disposed on the upper mounting plate 9 such that the step height of the upper flute 7b1 is larger than the step height of the lower flute 7b2 when in use.

  In the mounting pallet 1 configured as described above, as shown in FIG. 1A, after the object to be packaged 2 is mounted on the top plate 6, the band 3 passing through the insertion space s of the mounting portion 4 is The product 2 can be fixed to the mounting pallet 1 by winding the product around the item to be packed 2 while sandwiching the paper angle 14. And the mounting pallet 1 which mounted the to-be-packaged object 2 in this way is lifted by the nail | claw part of the forklift inserted between the leg parts 5, and is conveyed.

  As described above, the mounting pallet 1 of the present embodiment includes the mounting portion 4 and the two leg portions 5. The two legs 5 are disposed closer to both ends 4a of the mounting portion 4 parallel to the center line CL than the center line CL, and the extending direction of each flute 7b is perpendicular to the surface direction A plurality of corrugated paper sheets 7 are pasted together so that Further, in the mounting portion 4, the upper mounting plate 9 to which a plurality of corrugated cardboard sheets 7 are pasted together so that the extending directions of the respective flutes 7 b intersect, and the extending direction of the respective flutes 7 b is the mounting portion 4 The plurality of corrugated paperboards 7 are bonded together so as to be perpendicular to the surface direction of the plurality of spacer pieces 12 extending in the direction orthogonal to the longitudinal direction of the leg 5 in the longitudinal direction. It has the lower mounting board 10 by which the several corrugated paper 7 was bonded together so that the extension direction of each arrange | positioned honeycomb layer 11 and the flute 7b may cross | intersect. The honeycomb layer 11 is disposed between the upper placement plate 9 and the lower placement plate 10 and is fixed to the upper placement plate 9 and the lower placement plate 10, respectively. Thus, despite the fact that both the mounting portion 4 and the leg portion 5 are made of the corrugated paper 7, sufficient rigidity and strength are secured to load the stacked sheet-like objects 2 to be packed. In addition, weight reduction and cost reduction are possible.

  Further, since the honeycomb layer 11 arranges the plurality of spacer pieces 12 at intervals in the longitudinal direction of the leg 5, the number of parts can be reduced and the weight can be reduced, and the insertion space s of the band 3 can be further reduced. It can be secured.

  In addition, since the loading pallet 1 formed from the corrugated paper 7 is lighter than the wooden pallet, the amount of the loadable articles 2 can be increased in a truck or the like in which the loading weight is limited, Transport efficiency can be improved.

  Furthermore, since the placement unit 4 further includes the top plate 6 which is larger than the upper placement plate 9 and the double fluted corrugated board paper 8 whose step height of the upper flute 7b1 is larger than the step height of the lower flute 7b2, Even if it is the to-be-packaged goods 2 of a size larger than the upper mounting board 9 by using the top plate 6 according to the magnitude | size of the thing 2, to-be-packaged without the peripheral part of the to-be-packaged goods 2 curving The object 2 can be placed. Further, by using the top plate 6 so that the step height of the upper flute 7b1 is larger than the step height of the lower flute 7b2, the weight of the object 2 to be packed can be received by the highly damp upper flute 7b. The shift when the top 6 is deformed can be suppressed.

  FIG. 4A to FIG. 4C show a mounting pallet according to a first modification of the present embodiment. The mounting pallet 1 of the present modification is attached to the outer surface of the two legs 5 by a plurality (three in the present modification) each, and a plurality of substantially triangular plates (supporting the lower surface of the top plate 6) In this modification, six reinforcing members 13 are further provided.

Each reinforcing member 13 is formed by bonding a plurality of corrugated paper sheets 7 along the longitudinal direction of the leg portion 5, and the extending direction of the flutes 7b of the corrugated paper sheets 7 is perpendicular to the surface direction of the mounting portion 4. It is formed as. Then, as shown in FIG. 4B, one side of the substantially triangular plate-like reinforcing member 13 is bonded to the outer side surface of the leg portion 5, and another side of the reinforcing member 13 supports the lower surface of the top plate 6. One side of the reinforcing member 13 may also be bonded to the side surface of the lower mounting plate 10, the spacer piece 12 and the upper mounting plate 9. In addition, another side of the reinforcing member 13 may be bonded to the lower surface of the top plate 6.
In addition, a notch 13a is formed at one corner to be bonded to the leg portion 5 of the reinforcing member 13 and one corner to support the top plate 6.

  Thereby, the three reinforcing members 13 can reinforce the vicinity of both edges of the top plate 6, and when the load of the item to be packaged 2 is received, the top plate 6 and hence the item to be packaged 2 are curved. Can be further suppressed.
