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

  1 and 2 are perspective views showing the appearance of a pallet according to the first embodiment of the present invention. FIG. 1 is a perspective view of the pallet as seen from above, and FIG. 2 is a view as seen from below.

  The pallet 1 shown in FIGS. 1 and 2 includes an upper deck board 11, three girder members 12, and a lower deck board 13.

  The top deck board 11 is a rectangular plate on which a load is placed.

  The lower deck board 13 is a rectangular plate having substantially the same size as the upper deck board 11 and thinner than the upper deck board 11. The bottom deck board 13 ensures stability when the pallets 1 are stacked or when the pallets 1 are stacked with a load placed thereon. As shown in FIG. 2, the bottom deck board 13 has four holes 131 (131a, 131b, 131c, 131d). Here, the gravitational direction in the normal use state in which the pallet 1 places a load is referred to as a vertical direction Z. The upper deck board 11 and the lower deck board 13 extend in a direction intersecting with the vertical direction Z.

  The girder member 12 is attached to the lower surface opposite to the upper surface of the upper deck board 11 and supports the upper deck board 11 from below. The girder member 12 forms a space for inserting a forklift (not shown) or a fork (claw) of a handlift (not shown) under the upper deck board 11, that is, between the upper deck board 11 and the lower deck board 13. The pallet 1 of the present embodiment is a two-way pallet, and three girder members 12 extending long in the front-rear direction Y are arranged side by side in the left-right direction X. A fork can be inserted into the two spaces formed between the central beam member 12 and the left and right beam members 12 from the front or the rear in the front-rear direction Y.

  The four holes 131a to 131d vacated in the lower deck board 13 pass through the three girder members 12 and are arranged in two rows. Of the four holes 131a to 131d, the two holes 131a and 131b are arranged in the first row L1 extending in the front-rear direction Y into which the fork is inserted, and the remaining two holes 131c and 131d are arranged in the front-rear direction Y. They are arranged in the extended second row L2.

  The upper deck board 11, the girder member 12, and the lower deck board 13 are all made of paper, and are fixed to each other with an adhesive. The adhesive is, for example, a paste made from corn starch. The paper pallet 1 is lighter than, for example, a wooden or resin pallet. Moreover, since the paper pallet 1 can be recycled as a paper material even after its role as a pallet is finished, it is easy to reuse it as a resource.

  Here, the upper surface deck board 11 corresponds to an example of a mounting plate according to the present invention, the girder member 12 corresponds to an example of a support member according to the present invention, and the lower surface deck board 13 corresponds to an example of a laying plate according to the present invention. Equivalent to.

  FIG. 3 is a front view showing a usage state of the pallet shown in FIGS. 1 and 2.

  On the pallet 1, a luggage A is placed. The luggage A is placed on the upper surface deck board 11 of the pallet 1, and the upper surface deck board 11 is bundled together with the luggage A by a band B. When the cargo A is transported, for example, by a forklift or a hand lifter, a fork (not shown) of the forklift or hand lifter is inserted between the upper deck board 11 and the lower deck board 13 and the pallet 1 is lifted.

  Although one box is shown in FIG. 2 as the luggage A, the luggage A is not limited to a single item. For example, a plurality of small boxes may be stacked on the luggage A, and a plurality of small boxes may be integrated by winding an outer periphery of the luggage A with, for example, a stretchable resin film.

  The two bands B that bind the luggage A and the upper deck board 11 are, for example, resin-made binding bands, for example, so-called PP bands in which polypropylene fibers are knitted into flat strings. The band B has, for example, a width of about 15 mm and a thickness of about 0.6 mm. Each of the two bands B forms a ring by heat-sealing the overlapping portions in the vicinity of both ends over a length of about 20 mm with the pallet 1 and the load A tightened, and the pallet 1 and the load A Is tightened with a strong force that does not collapse during transportation. In addition to forming the ring by heat fusion, the band B is connected by a band buckle (not shown) to form a ring, and the end is drawn down, so that the pallet 1 and the luggage A May be tightened.

  FIG. 4 is a perspective view showing a pallet and a hand lift for carrying a load.

  The hand lift 5 includes a fork (claw) 51 inserted into the pallet 1, a handle 52 for operating the hand lift 5, a load wheel 53 that supports a load from the fork 51, and a direction change It has a steering wheel 54 that is a wheel. Two load wheels 53 are provided, and are attached below the tip of the fork 51.

  When the worker carries the pallet 1 with the load A shown in FIG. 3 with the hand lift 5, the worker holds the handle 52, pushes the hand lift 5, and moves the fork 51 to the upper deck board 11 and the lower surface of the pallet 1. Insert between the deck board 13. The fork 51 is inserted in the front-rear direction Y (FIGS. 1 and 2) of the pallet 1. At this time, the two load wheels 53 provided at the front end portion of the fork 51 ride on the lower deck board 13 of the pallet 1 and proceed along the first row L1 and the second row L2. When the load wheel 53 enters the hole 131 disposed on the back side of each of the rows L1 and L2, the load wheel 53 directly contacts the floor surface. When the operator tilts the handle 52 while the load wheel 53 is in contact with the floor surface, the fork 51 rises and lifts the pallet 1. At this time, the load from the top deck board 11 is supported on the floor surface via the fork 51 and the load wheel 53. When the fork 51 lifts the pallet 1 and the operator pulls the handlift 5 with the handle 52, the load A (see FIG. 3) is conveyed by the handlift 5 together with the pallet 1.

[Top deck board structure]
FIG. 5 is an enlarged perspective view showing the structure of the top deck board shown in FIGS.

  The top deck board 11 has an internal structure in which cylindrical cells extending in the up-down direction Z are arranged in the left-right direction X and the front-rear direction Y.

The upper deck board 11 includes a front liner 113 disposed on the upper surface on which the luggage A (see FIG. 3 ) is placed, a rear liner 114 disposed on the girder member 12 (see FIG. 3) side, and the front liner 113 and the rear liner 114. The honeycomb core material 112 is sandwiched between the two. FIG. 5 shows a state in which a part of the surface liner 113 is removed for easy viewing of the structure. The upper deck board 11 has a structure different from that of ordinary cardboard, that is, a paperboard having a structure in which front and back liners are bonded to a peak portion and a valley portion of one core material formed in a wave shape. The top liner 113 and the back liner 114 of the top deck board 11 are each a sheet of paper, and are bonded to the honeycomb core material 112. Here, the upper surface of the upper deck board 11 on which the front liner 113 is disposed corresponds to an example of the first surface according to the present invention, and the lower surface on which the rear liner 114 is disposed is an example of the second surface according to the present invention. It corresponds to. The honeycomb core material 112 is a honeycomb cell in which a plurality of papers formed in a wave shape are bonded together by adhering wave crests and troughs between adjacent papers. It has a structure. Each of the cylindrical cells formed in the honeycomb core material 112 extends in the up-down direction Z intersecting the surface liner 113, and the cylindrical cells extend in the front-rear direction Y and the left-right direction X in which the surface liner 113 spreads. They are arranged in two dimensions. Although the cylindrical cell of the honeycomb core material 112 is not a complete hexagon, the top deck board 11 can be said to have a honeycomb structure. The top deck board 11 having a honeycomb structure has a higher bending strength with respect to the load in the vertical direction Z than, for example, the above-described normal cardboard. Therefore, heavier loads can be placed on top. Further, the pallet 1 is not easily deformed when a fork (not shown) is inserted into a pallet (see FIG. 3) and lifted, or when a plurality of layers are stacked up and down with a load fixed on the pallet. The upper deck board 11 has a higher bending strength with respect to a load in the vertical direction Z as the thickness in the vertical direction Z is larger, that is, as the cylindrical cell is longer. The thickness of the top deck board 11 is, for example, about 20 mm to 45 mm, but the thickness can be selected according to the load of the load. Further, the top deck board 11 is made of paper and has many cavities, so that it is lighter than a wooden board having the same strength.

  Here, the material of the upper deck board 11 will be described. The front liner 113 and the back liner 114 are made of a paper tube base paper having a basis weight of about 650 g / m 2, for example. The honeycomb core material 112 is paper that is thinner than the front liner 113 and the back liner 114 and has a basis weight of, for example, 160 g / m 2. More specifically, the honeycomb core material 112 is a semi-chemical pulp paper that is a pulp paper manufactured by mechanically loosening chips softened by removing a part of nigrin in wood by chemical treatment. However, for the front liner 113, the back liner 114, and the honeycomb core material 112, paper manufactured by other processes and having a basis weight different from that described above may be employed. An adhesive that bonds the papers constituting the honeycomb core material 112, an adhesive that bonds the honeycomb core material 112 and the front liner 113, and an adhesive that bonds the honeycomb core material 112 and the back liner 114 are, for example, vinyl acetate type It is an adhesive.

  The girder member 12 in the pallet 1 of the present embodiment has a honeycomb structure in which cylindrical cells extend in the up-down direction Z, similarly to the top deck board 11 described with reference to FIG. However, the girder member 12 is thicker than the top deck board 11 and has a thickness (height) of about 50 mm or more and 80 mm or less in order to secure a space for inserting a fork.

[Structure of bottom deck board]
FIG. 6 is an enlarged side view showing a part of the lower deck board 13.

  The lower deck board 13 does not have a bending strength with respect to the load of the load as compared with the upper deck board 11, and therefore does not have a honeycomb structure, and is a normal corrugated cardboard, that is, a single core material formed in a wavy shape. It is made of paperboard having a structure in which front and back liners are bonded to the crest and trough portions. More specifically, the lower deck board 13 is composed of a double-sided cardboard in which a single-sided corrugated cardboard step, that is, a wave crest and a trough are bonded to one side of a double-sided cardboard.

  Specifically, the bottom deck board 13 has two liners 1302 and 1303 attached to the front and back of one core member 1301 formed in a wave shape so as to adhere to the crest and trough portions of the wave. Furthermore, another core material 1304 formed in a wave shape is laminated and pasted on one liner 1303 of these two sheets so as to adhere to the peak and valley portions of the wave, and further another The liner 1305 has a structure in which the core material 130 is laminated and pasted so as to adhere to the wave crest and trough portions of the core material 130. The thickness of the lower deck board 13 is about 8 mm, for example. In the two core members 1301 and 1304, the flute directions in which the peak of the mountain and the bottom of the valley in the formed wave extend are aligned in the same direction. In FIG. 6, the flow direction intersecting with the flute direction, that is, the flow direction in which peaks and valleys are arranged is indicated by an arrow. Corrugated cardboard has a characteristic that strength against tensile force and compressive force in the flute direction is stronger than strength against tensile force and compressive force in the flow direction.

  In the pallet 1 shown in FIG. 1, the lower deck board 13 is arranged in a posture in which the cardboard flow direction (see FIG. 6) is matched with the front-rear direction Y in which the three girder members 12 extend. That is, the fork 51 (see FIG. 4) of the handlift 5 is inserted into the pallet 1 in the front-rear direction Y, which is the cardboard flow direction (see FIG. 6).

  In the state where the pallet 1 shown in FIG. 1 is lifted by the fork 51 (see FIG. 4), a compressive force in the left-right direction X that intersects the front-rear direction Y in which the fork 51 extends acts on the lower deck board 13. Further, when the pallet 1 is placed on a storage table that is supported from below near both ends in the left-right direction X, for example, referred to as a double-supported rack, a pulling force in the left-right direction X acts on the bottom deck board 13. To do. The bottom deck board 13 of the pallet 1 has the cardboard flow direction (see FIG. 6) aligned with the front-rear direction Y and the flute direction aligned with the left-right direction X. Compared with the case where it was done, the intensity | strength with respect to the force applied in the use condition of the pallet 1 is high, and the load bearing strength of the pallet 1 is high.

  FIG. 7 is a plan view showing the lower deck board with the upper deck board and the girder member removed. FIG. 7 shows a surface of the bottom deck board opposite to the surface appearing in FIG. FIG. 8 is a cross-sectional view showing a cross section taken along line AA of the bottom deck board shown in FIG.

  The bottom deck board 13 has four holes 131a to 131d. The four holes 131a to 131d are formed in two rows L1 and L2 extending in the front-rear direction Y into which the fork 51 (see FIG. 4) is inserted. They are lined up. FIG. 8 shows a cross section passing through the two holes 131a and 131b arranged in the row L1. Each of the four holes 131a to 131d has a rectangular shape and has edges corresponding to the four sides. Of the edges of the two holes 131a and 131b arranged in one row L1, the edge 1311, which extends in the left-right direction X intersecting with the row L1 and is positioned between the holes 131a and 131b, is provided in each of the holes 131a and 131b. A first folded portion 1312 that is folded outward is provided. Of the edges of the two holes 131c and 131d arranged in the row L2 adjacent to the row L1, the edge 1311 that extends in the left-right direction X intersecting the row L2 and is positioned between the holes 131c and 131d, A first folded portion 1312 is provided that is folded toward the outside of each of the holes 131c and 131d.

  Of the lower deck board 13, the thickness of the portion where the first folded portion 1312 is provided is thicker than the other portions. Specifically, the portion where the first folded portion 1312 is provided has twice the thickness of the portion where the first folded portion 1312 is not provided.

Furthermore, two holes 131a arranged in rows L1, among 131b of the edge, extending in the lateral direction X intersecting the rows L1, and the edge 1 3 13 located at the end of the line L1, that is, the first bent portion 1312 A second folded portion 1314 that is folded outward from the holes 131a and 131b is also provided on the edge 1 3 13 on the side opposite to the provided edge 1311. Further, two holes 131c aligned in the column L2 of the adjacent column L1, among 131d edge, it is extending in the lateral direction X intersecting the row L2, and the edge 1 3 13 located at the end of the line L2, i.e. the first the other side edge 1 3 13 edge 1311 folded portion 1312 is provided, the hole 131c, is folded toward the outside of 131d respectively, the second folded portion 1314 is provided.

The second folded portion 1314 is extends from the edge 1 3 13 toward the outer edge 13a of the lower surface deck board 13, do not reach the outer edge 13a, the tip of the second folded portion 1314 is folded, the bottom surface deck The board 13 is located away from the outer edge 13a and inside the outer edge 13a.

  FIG. 9 is a developed view of the bottom deck board shown in FIGS. 7 and 8.

  The bottom deck board 13 shown in FIGS. 7 and 8 is formed by forming a cut line indicated by a solid line on the corrugated board shown in FIG. 9, folding the broken line part, and fixing the folded part with an adhesive or a stapler. . The hole 131, the first folded portion 1312, and the second folded portion 1314 can be formed at a time by folding the cardboard with a cut. In FIG. 9, reference numerals are shown in parentheses for a portion that becomes the first folding portion 1312 and a portion that becomes the second folding portion 1314. The first folded portion 1312 and the second folded portion 1314 are formed using a portion of the cardboard that is originally discarded when the hole 131 is opened, and other than the cardboard that constitutes the bottom deck board 13. The thickness is increased without using a member.

  FIG. 10 is a cross-sectional view showing a state in which the hand lift fork is inserted into the pallet.

  When the operator pushes the hand lift 5 shown in FIG. 4 and inserts the fork 51 in the front-rear direction Y between the upper deck board 11 and the lower deck board 13 of the pallet 1 placed on the floor surface, The attached road wheel 53 rides on the lower deck board 13 and advances. At this time, the road wheel 53 rides on the lower deck board 13 from the outer edge 13 a of the lower deck board 13, above the second folding part 1314, the front hole 131 a (floor surface), and above the first folding part 1312. To reach the hole 131b (floor surface) on the back side. The load wheel 53 is in contact with the floor surface on which the pallet 1 is placed at the position of the hole 131b shown in FIG. In this state, when the operator operates the handle 52 (see FIG. 4) to raise the fork 51, the fork 51 lifts the pallet 1. At this time, the load from the top deck board 11 including the luggage A (see FIG. 3) is supported on the floor surface via the fork 51 and the load wheel 53. In a state where the fork 51 lifts the pallet 1, the operator pulls the hand lift 5 to convey the luggage A and the pallet 1.

  Here, for example, when the operator raises the fork 51, if the load wheel 53 is not on the hole 131b and remains on the lower deck board 13, the fork 51 rises. While 51 applies a pushing force to the upper deck board 11, the load wheel 53 applies a pushing force to the lower deck board 13. As a result, the upper deck board 11 is not lifted, and the upper deck board 11 or the lower deck board 13 may be detached from the girder member 12 and the pallet 1 may be damaged. Therefore, when the operator inserts the fork 51 into the pallet 1, it is necessary to stop the load wheel 53 at the position of the hole 131b.

  When the fork 51 is inserted into the pallet 1, the load wheel 53 is hidden under the top deck board 11 and the load, and the position cannot be visually recognized by the operator. The operator recognizes that the load wheel 53 has come to the position of the hole 131b by the response that the impact caused by the load wheel 53 falling into the hole 131b is transmitted through the handle 52.

  The pallet 1 according to the present embodiment is arranged in the left-right direction X intersecting the row L1 among the edges of the two holes 131a and 131b arranged in the row L1 (see FIG. 2) extending in the front-rear direction Y which is the insertion direction of the fork 51. The edge 1311 that extends and is located between the holes 131a and 131b is provided with a first folded portion 1312 that is folded outward from the holes 131a and 131b. The provided portion is thicker than the portion where the first folded portion 1312 is not provided. That is, the level difference G where the load wheel 53 falls into the hole 131b is larger than that in the case where the first folded portion 1312 is not provided, for example. For this reason, the impact when the load wheel 53 falls into the hole 131b, that is, the response of the handle 52 is strong. The same applies to the holes 131d arranged in the other row L2. Therefore, it is reliably notified to the operator of the handlift that the fork 51 has been inserted to a position where the pallet 1 can be lifted.

  For example, if the lower deck board 13 is not provided with the first folded portion 1312 and the edge of the hole 131a is formed of a single cardboard, the cardboard is crushed and thinned, and the handle 52 is less responsive. It becomes difficult to determine the position.

  Since the pallet 1 of this embodiment is provided with the first folding part 1312, the thickness is twice that of the case where the first folding part 1312 is not provided. Further, the edge of the hole 131b is strengthened by being folded back. Therefore, compared with the case where the 1st folding | turning part 1312 is not provided, corrugated cardboard is crushed and thinned, and it is suppressed that the response becomes weak.

  The bottom deck board 13 according to the present embodiment is provided with front-side holes 131a and 131c and back-side holes 131b and 131d, respectively, in each of the two rows L1 and L2, both of which have folding portions. Although they are adjacent to each other, the positions in the front-rear direction Y are greatly different between the front side and the back side, and therefore it is easy to determine which hole the load wheel 53 is in.

  The tip of the second folded portion 1314 provided on the lower deck board 13 is folded back at a position inside the outer edge 13 a of the lower deck board 13. For this reason, when the fork 51 is inserted, the outer edge 13a of the lower deck board 13 on which the road wheel 53 rides has a height equivalent to the thickness of one cardboard, and after the road wheel 53 gets on the outer edge 13a, the cardboard 1 It rides on the 1st folding | turning part 1312 which has the height for the thickness of a sheet | seat. Therefore, the impact when the road wheel 53 rides on the first folded portion 1312 is smaller than, for example, when the tip of the second folded portion 1314 reaches the outer edge 13a of the lower deck board 13.

Further, two holes 231a arranged in rows L1, among the edges of the 231b, extending in the lateral direction X intersecting the rows L1, and the edge 2 3 13 positioned at the end of the line L1, that is, the first bent portion 2312 Also on the edge 2 3 13 opposite to the provided edge 2311, a second folded portion 2314 is provided that is folded toward the outside of the holes 231 a and 231 b.

  The structure described for the rows L1 and L2 extending in the front-rear direction Y is the same for the rows L3 and L4 extending 90 degrees and extending in the left-right direction X. That is, among the edges of the two holes 231b and 231d arranged in the row L3 extending in the left-right direction X, the edge 2311 extending in the front-rear direction Y intersecting the row L3 and positioned between the holes 231b and 231d is A first folded portion 2312 is provided that is folded toward the outside of each of the holes 231b and 231d. Of the edges of the two holes 231a and 231c arranged in the row L4 adjacent to the row L3, the edge 2311 extending in the front-rear direction Y intersecting the row L4 and positioned between the holes 231a and 231c A first folded portion 2312 is provided that is folded toward the outside of each of the holes 231a and 231c.

Furthermore, the other side edge 2 3 13 of the first folded portion 2312 is provided with edge 2311, the hole 231b, folded towards the outside of 231d respectively, the second folded portion 2314 is provided.

  As described above, the lower deck board 23 in the second embodiment is provided with the folded portions that are folded outward with respect to all the edges of the four holes 231a to 231d.

  FIG. 14 is a development view of the bottom deck board shown in FIG.

  The bottom deck board 23 shown in FIG. 13 is formed by forming a cut line indicated by a solid line on the corrugated board shown in FIG. 14, folding the broken line part, and fixing the folded part with an adhesive or a stapler.

  The pallet 2 of the second embodiment is a four-way pallet, and there are more directions in which the forks 51 (see FIG. 4) can be inserted than the pallet 1 of the first embodiment. Therefore, the degree of freedom in handling is high. In addition, in all directions in which the fork 51 can be inserted, that is, in both the left-right direction X and the front-rear direction Y, the first turn-back portion 2312 is provided for the edge 2311 located between the two holes 231 arranged side by side. The edge 2311 portion is thicker than the portion where the first folded portion 2312 is not provided. Therefore, the level | step difference which the load wheel 53 falls to the hole 131b is large compared with the case where the 1st folding | turning part 2312 is not provided, for example. That is, in all directions in which the fork 51 can be inserted, the hand lift operator reliably determines that the fork 51 has been inserted to a position where the pallet 2 can be lifted.

  Here, the first embodiment will be described again. Since the pallet 1 of the first embodiment shown in FIGS. 1 and 2 is a two-way pallet, it has a structure in which three girder members 12 extend long in the front-rear direction Y along the rows L1 and L2. Yes. Therefore, it is more robust than the four-way pallet 2 shown in FIG. 11 in which the girder members 22 are intermittently arranged along the rows.

  Moreover, as shown in FIG. 7, the pallet 1 of 1st Embodiment does not bend the edge extended in the direction of row | line | column L1, L2 among the four edges of each hole 131, but cross | intersects row | line | column L1, L2. The first folded portion 1312 of the edge 1311 extending in the direction is rectangular. For this reason, the edge of the first folded portion 1312 that is folded and extended is formed only by a straight line that extends in the left-right direction X that intersects the insertion direction of the fork 51. For this reason, for example, as shown in FIG. 13, the traveling direction of the load wheel 53 that rides on the first folded portion 1312 is careless compared to the case where the bent edge extends obliquely with respect to the insertion direction. The situation of bending is suppressed.

  In addition, in embodiment mentioned above, it has the 1st folding | turning part 1312 folded back outward about the edge located between the two holes located in a line as an example of the laying board said to this invention, Although the lower deck board 13 having the second folded portion 1314 that is folded outward also on the opposite edge is shown, the present invention is not limited to this. For example, the laying boards are arranged in a row. Only the edge located between the two holes may be folded outward.

  In the above-described embodiment, the example of the bottom deck board made of double-sided corrugated cardboard is shown as an example of the laying board according to the present invention, but the present invention is not limited to this. It may be made of double-sided corrugated cardboard, single-sided cardboard, corrugated cardboard in which three or more double-sided cardboards are stacked, and may have a honeycomb structure or cardboard.

  In the above-described embodiment, as an example of the pallet according to the present invention, the pallet 1 including the upper surface deck board 11 and the girder member 12 having a honeycomb structure is shown, but the present invention is not limited to this. The mounting plate and the support member may be formed of ordinary cardboard instead of the honeycomb structure.

  In the above-described embodiment, the bottom deck board 13 having a total of four holes is shown as an example of the floor board according to the present invention. However, the present invention is not limited to this, and for example, the floor board In addition to the above four holes, holes may be formed.

  In the above-described embodiment, the upper deck board 11 made of a single plate is shown as an example of the mounting plate according to the present invention. However, the present invention is not limited to this, and there are, for example, a plurality of mounting plates. The plates may be arranged side by side.
