Description

Technical Paper Paper Pallet Technical Field

The present invention relates to a paper-making machine, which is less deformed or damaged when carrying heavy cargo or cargo having an eccentric load by forklift, and is inexpensive to manufacture. You. Background art

Conventionally, a paper pallet including a top plate and two or more leg members directly adhered to the back surface of the top plate has been known.

For example, Japanese Utility Model Publication No. 48-6994 discloses that cardboard or other thick paper is rolled between a corrugated cardboard top plate and a bottom plate to form a columnar leg member. It also discloses a paper pallet having the other end adhered to the surface of the bottom plate.

Also, No. 1 144 4 4 27, the corrugated column-shaped leg members, which are made by bending the corrugated pole so that the cross section becomes a U-shape and filling it with filler, A paper pallet directly bonded to the back of the top plate in a girder form is shown.

Japanese Utility Model No. 5-266036 also discloses a leg member that bends a corrugated cardboard so that its cross-section becomes a mouth shape, and arranges a corrugated cardboard columnar member in it. It discloses a paper pallet directly bonded in a girder shape to the back of a corrugated cardboard top plate.

When the paper pallets described above are lifted and transported by forklift, the forks of the forklift directly support the back of the top plate made of step poles. And Therefore, the full load of the cargo mounted on the top plate is supported only by the top plate, and when the load of this cargo exceeds the load capacity of the top plate, the step pole The plate is broken or the corrugated structure of the step pole is crushed around the part where the fork contacts, and the strength of the top plate is significantly impaired. For this reason, the above paper pallets can be used for relatively light cargo, but cannot be used for heavy cargo. There was a point.

To deal with the problems of the paper pallets described above, Japanese Patent Publication No. 7-49301 discloses two or more leg members obtained by bending a corrugated cardboard several times, and the leg members. A plurality of corrugated deck members made of corrugated cardboard, which are manufactured by folding and bending in multiple layers in the same manner as described above, and each leg member and deck member are fitted orthogonally to each other. Disclosure.

When the paper pallet is lifted and transported by a forklift, the fork of the forklift supports the lower surface of the deck member, as described above. Since the strength is greatly improved compared to a simple corrugated board, no problems such as breakage will occur. However, in order to form deck members that do not deform or break the pallet when carrying heavy loads, it is necessary to bend the cardboard several times, and However, in order to obtain sufficient strength, it is necessary to use a large amount of high-quality corrugated cardboard sheets, so that there is a problem that the production cost increases. Also, since the cardboard is used for the deck member in this paper pallet, the corrugated structure of the cardboard is crushed and the strength of the deck member is remarkable. The problem of lowering remains.

In view of the above, an object of the present invention is to provide a paper pallet that is not deformed or damaged when transported by forklift, and that is inexpensive to manufacture. . Disclosure of the invention

The paper pallet of the present invention is a cargo mounting member in which two or more paper tubes or cutting members in the axial direction of the paper tube are connected in a frame or lattice shape, and is disposed below the cargo mounting member. It has a leg member and a leg. This paper tube has a very excellent strength because it is manufactured by winding a number of layers while applying an adhesive to a machine-made winding base paper represented by a paper tube base paper. In addition, this paper tube is mainly used as the core material of base paper rolls such as newsprint, but it can be obtained at extremely low cost as waste after use. Or, they are arranged in a grid. That is, when the fork of the forklift is inserted below the paper pallet, the fork is always inserted in a part of the paper tube or in the axial direction of the paper tube. This is so as to be perpendicular to the axial direction of the material.

Further, the paper pallet of the present invention requires leg members as essential components. In other words, in order to make the insertion direction of the fork perpendicular to the axial direction of some paper tubes, it is necessary to secure a space for inserting the fork under the cargo mounting member. It is. Therefore, the paper pallet of the present invention can make the most of the strength of the paper tube when transported by forklift. In addition, not only the paper core but also a cut material obtained by cutting the paper core in the axial direction can be used for the above-mentioned cargo mounting member. In this case, the length of the paper tube can be used effectively. The connection method of the paper tube or the cutting material in the axial direction of the paper tube is performed by bonding with an adhesive, or by using a nail such as a stitcher or by fitting a notch in the connection part. The method can be adopted.

Further, a paper pallet of the present invention is a cargo mounting member in which two or more paper tubes or paper tube axial cutting materials are arranged in a girder, frame, or lattice shape. And a leg member disposed below the cargo mounting member and supporting the cargo mounting member. This is a structure in which two or more cargo-carrying members are connected by leg members. In other words, even if the cargo mounting members are not connected to each other as in the paper pallet described above, it is sufficient if the cargo mounting members are connected by the leg members. . For example, in the case where a cargo mounting member is bridged between a pair of leg members in a girder form, the leg members are attached after manufacturing a lattice-like cargo mounting member. Instead of two processes, it can be produced in one process, in which cargo mounting members are attached to leg members.

Further, the paper pallet of the present invention is characterized in that a top plate and two or more paper tubes or paper tube axial cutting materials on the back surface of the top plate are in a girder shape, a frame shape or a lattice shape. And a leg member disposed below the top plate reinforcing member. This is a paper pallet that supports cargo with a top plate, and a paper tube is provided as a reinforcing member for the top plate. Also in this case, when the fork of the forklift is inserted below the nozzle, the insertion direction of the fork is orthogonal to the axial direction of the paper tube or the like. Requires components. Also, the fork does not directly support the top plate but supports the top plate reinforcing member, so that deformation and damage of the top plate can be prevented.

Further, it is preferable that the leg member is a paper tube or a paper tube axial direction cutting material arranged so that the axial direction is horizontal. In this case, the leg members can be easily produced by cutting a paper tube or the like into a certain length. In addition, since the paper tube is not arranged so that the axial direction of the paper tube is vertical, the cutting length of the paper tube and the like does not become the height of the leg member, and therefore, each leg member has the same diameter. This can prevent the paper pallets from being displaced due to uneven heights of the leg members. Also, by changing the length of the paper core, the fork insertion position can be regulated.

In addition, the leg members arranged so that the axis direction is horizontal are In the paper pallet, it is preferable that the cargo mounting member (or the top plate reinforcing member) and the leg member have a flat surface at a joint portion. By providing a flat portion on the paper tube, etc., it is possible to prevent rolling during assembly, thereby facilitating the assembling work. The strength of the whole ret can be secured. Similarly, in the case of the paper pallet provided with the top plate of the present invention, a flat surface can be provided on the top plate reinforcing member, and the joining with the top plate can be ensured.

Further, in a paper pallet having a leg member arranged such that the axial direction is horizontal, it is preferable to provide a flat surface on the lower surface of the leg member. This prevents rolling during assembly and increases the ground contact area of the leg members. For example, when a paper pallet is loaded, the paper pallet becomes unsteady due to the sway of the ship. It is difficult to shift. Also, the compressive strength can be greatly increased by cutting the paper tube to some extent rather than using it as it is.

In addition, it is preferable that the cargo mounting member (or the top plate reinforcing member) and the leg member are cut off at an overhanging portion. When paper pallets loaded with cargo are stacked, the legs of the upper paper pallet are placed near the outer wall surface of the lower cargo, so the lower cargo Dents and bends on the upper surface of the top plate can be prevented.

Further, it is preferable that the leg member is waterproofed. This is because it is possible to prevent a decrease in strength due to the water content of the leg member and also to expect a protective effect. BRIEF DESCRIPTION OF THE FIGURES

The paper pallet of this embodiment is formed by cutting off the overhang portion of the leg member 125. That is, in FIG. 32, the left side of the leg member 125 is cut off to form a cut surface 130. Therefore, the leg members 125 can be arranged on the outer side of the pallet. In FIG. 32, since the left side of the top plate reinforcing member 122 is not cut off, the flat surface 134 is slightly shifted and adhered to the flat surface 132 of the leg member 125. . However, the left side of the top plate reinforcing member 1 2 2 was cut off in the same way as the leg members 1 2 5, and the flat surface 1 3 4 and the flat surface 1 3 2 were bonded together. You may let it. The left side of the top plate reinforcement member 122 must be cut, but the joint between the top plate reinforcement member 122 and the leg member 125 will be stronger.

As described above, the overhang portion is cut off, and the leg members 125 are arranged closer to the outside of the pallet. Therefore, the flat surface 131 is located closer to the outside of the pallet. . Therefore, the loads of cargoes A and P, let P12 are applied to the top surface of cargo B near the side wall where the strength is relatively high. Therefore, the paper pallet of the present embodiment is capable of stacking pallets loaded with cargo by cutting off the overhanging portions of the leg members 125. It is possible to prevent the upper surface of the top plate of the placed lower cargo from being dented or bent.

Further, the leg members 125, 126, 127, 128 of this embodiment are waterproofed. These leg members have a flat surface and a cut section as shown in the figure, and the cross section of the paper tube is exposed, so that it is easy to absorb moisture. Paper tubes have higher water resistance than paperboard, but waterproofing is effective against dew condensation on the floor. The waterproofing is performed by using a known water-repellent, water-blocking or water-resistant impregnating agent, such as resin or wax, on the entire paper core or only on the cross-section. In addition, since the main purpose is to prevent water sprinkling and dew condensation on the floor surface, a sufficient effect can be obtained if the waterproofing is applied at a height of 5 to 1 Om m above the ground contact surface. The leg member according to the present embodiment can prevent the strength from being reduced due to the inclusion of moisture and can achieve the heat-proof effect.

In the first to fourth embodiments, the cargo is directly mounted on the upper surface of the cargo mounting member without the top plate. However, in these embodiments, a top plate may be provided on the upper surface of the cargo mounting member. In this case, the cargo carrying member is referred to as the top plate reinforcing member. On the other hand, the fifth to 12th embodiments have a top plate, and the cargo is placed on the upper surface of the top plate. However, in these embodiments, the cargo may be placed directly on the upper surface of the top plate reinforcing member without providing the top plate. In this case, the top plate reinforcing member is called a cargo mounting member. The first, third, fifth, sixth, seventh, eighth, ninth, and ninth embodiments 2 The cargo mounting member or the top plate reinforcing member of the embodiment is disposed with the paper tube axial direction cross section facing upward. Has been done. On the other hand, the cargo mounting member or the top plate reinforcing member of the second embodiment, the tenth embodiment, and the eleventh embodiment is disposed with the cross section in the paper tube axial direction downward. However, the direction in which these cargo-carrying members or top-plate reinforcing members are arranged can be selected as appropriate. If there is no advantage in using the cutting material in the axial direction of the paper tube in these examples, it is possible to use a paper tube that is not cut in the axial direction (for example, the fourth embodiment). is there.

In each of the above embodiments, the cargo mounting member or the top plate reinforcing member is disposed parallel or orthogonal to the extending direction of the leg member or the side of the top plate. However, if the fork of the forklift can support the lower surface of the cargo mounting member or the top plate reinforcing member, these cargo mounting members or the top plate reinforcing member have leg members.
