The widths of the board from both ends are approximately equal to the length of the diagonal of the rectangle that is ½ of the square, the length of one side of the square, the length of the short side of the rectangle, and the length of one side of the square. Is defined by the first to fourth cut lines, and the fourth cut line defines one fifth part whose width is substantially equal to the length of one side of the square, and is folded and bent. The opposite surfaces of the two parts are bonded.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a top plate of a paper pallet and legs of the paper pallet.

[0002]

[Prior art]

  Conventional wooden pallets are fumigated when used for export due to problems with epidemics. Is required, and resin pallets are expensive and difficult to dispose of. .

[0003]   In contrast, paper pallets are cheap, lightweight, and easy to dispose of. , Used a lot. For example, the paper pallet 30 shown in FIGS. On the paper tube 32 that is a plurality of (9 in the illustrated example) legs standing upright in the Is attached with a top plate 33 made of a two-layer corrugated paperboard.

[0004]

[Problems to be solved by the device]

  In this paper pallet 30, the corrugated plate 34 of the top plate 33 is naturally folded. The bending strength is small at the edge portion 33a in the direction orthogonal to the mountain c, and therefore, the load and There is a drawback that it is easily bent downward due to interference with obstacles.

[0005]   In addition, the paper tube 32 is bulky to be transported from the leg manufacturing factory to the pallet assembly factory. There is a drawback.

[0006]   The present invention has a paper pallet top plate with increased edge strength and is not bulky during transportation. It is intended to provide the legs of a paper pallet.

[0007]

[Means for Solving the Problems]

  The top plate of the paper pallet according to the present invention is composed of a paperboard top plate and a bottom plate. Dion pleated paper is sandwiched and the joints are bonded.

[0008]   The leg of the paper pallet according to the present invention has a rectangular shape with a width of ½ at both ends of the paperboard. Defining a pair of first portions substantially equal to the length of the diagonal line of the A pair of second parts continuous to the first part and having a width substantially equal to the length of one side of the square. It is defined by two score lines and is continuous with the second portion and has a width substantially equal to the length of the rectangular short piece. An equal pair of third portions is defined by a third score line, and the third portion is continuous with the width. A pair of fourth portions each having a length substantially equal to the length of one side of the square with a fourth score line. And a fifth width continuous with the fourth portion and having a width approximately equal to the length of one side of the square. Is defined by the fourth score line, and the same direction is defined from the first to fourth score lines. The pair of second portions of the first to fifth portions bent in the opposite direction are opposed to each other. The surface is glued.

[0009] The top plate and the top plate, for example a ^{1000g / m 2 ~1200g / m 2} , accordion pleats paper, for example, a ^{500g / m 2 ~700g / m 2} , the height of the pleats, for example by 20~30mm The number of pleats is preferably, for example, 60 to 70 per 800 mm (that is, the pitch is 11 to 13 mm).

Further, the paperboard of the legs is preferably 1200 g / m ² , for example.

[0011]   Also, it is advisable to use vinyl acetate emulsion adhesive or hot melt for adhesion. preferable.

[0012]

[Action]

  In the top plate of the paper pallet configured as above, the upper and lower plates are Since it holds onion pleated paper, the bending strength in the fold mountain direction is extremely large, Therefore, the bending of the edge portion in that direction is prevented.

[0013]   The legs of the paper pallet configured as described above were unfolded during transportation. The paperboards can be stacked to make the bulk very small.

[0014]

【Example】

  An embodiment of the present invention will be described below with reference to the drawings.

[0015]   1 to 3 include a top plate 10 according to the present invention and three legs 20. A paper pallet is shown generally at 1.

As shown in FIG. 4, the top plate 10 is formed by holding the accordion pleated paper 13 between the upper plate 11 and the lower plate 12 and bonding the joints with, for example, a vinyl acetate emulsion adhesive or hot melt. There is. Both plates 11 and 12 are formed of, for example, 1200 g / m ² of paperboard. The accordion pleated paper 13 is formed by folding a board of 600 g / m ² into a pleat height H of 20 to 30 mm and a pleat number of 60 to 70 per 800 mm (that is, a pitch P of 11 to 13 mm). Has been done.

As shown in FIGS. 5 and 6, the leg portion 20 is formed into a rectangular tube shape by folding a paperboard M having a thickness of 1200 g / m ² , for example. At both ends of the paper board M, a pair of first portions 21 1, 21 having a width W 1 substantially equal to the length of a diagonal line of a rectangle B that is ½ of the square A are cut lines L 1 from above in FIG. It is defined by L1. A pair of second portions 22 continuous with the first portions 21 and 21 and having a width W2 substantially equal to the length of one side of the square A are defined by cut lines L2 and L2. A pair of third portions 23, 23 continuous with the second portions 22, 22 and having a width W3 substantially equal to the length of the short side of the rectangle B are defined by cut lines L3, L3. A pair of fourth portions 24, 24 continuous with the third portions 23, 23 and having a width W4 approximately equal to the length of one side of the square A are defined by cut lines L4, L4. Then, one fifth portion 25 which is continuous with the fourth portions 24 and 24 and whose width W5 is substantially equal to the length of one side of the square A is defined by the cut lines L4 and L4.

[0018]   When assembling the leg part 20, all the parts 21 to 25 are mutually cut from the cut lines L1 to L4. Bend inward (downward in FIG. 6) and cover the second parts 22, 22 entirely with vinyl acetate. It is adhered with a Neil emulsion adhesive or hot melt to form a rectangular tube.   For assembling the pallet 1, the three legs 20, 20, 20 are arranged on the top plate 10 in the longitudinal direction. The third portion 23, 2 is formed so as to be orthogonal to the fold crest a of the accordion pleat 13. 3 to the lower surface of the lower plate 12 with a vinyl acetate emulsion adhesive or hot melt. Glue.

[0019]   Therefore, the bending strength of the top plate 10 is extremely large in the direction of the fold crest a, Also in the direction orthogonal to a, it is larger than the conventional one. As a result, the edge in the direction of the fold mountain a Bending of 10a is prevented.

[0020]   In addition, the paper tube 20 is made by stacking the paperboards M that have been developed at the time of transportation to make the volume very small. It is easy to carry.

[0021]

[Effect of device]

  Since the present invention is configured as described above, the strength of the top plate is increased, Bending can be prevented. Especially those who follow the ridge of the accordion pleats mountain The direction is strong and does not bend with the fork inserted.

[0022]   In addition, it is possible to reduce the bulkiness during transportation of the legs and facilitate transportation.
