Description

  The present invention relates to a pallet mainly made of cardboard.

Traditionally, wooden, metal, plastic, and paper pallets have been used for cargo handling, but wooden pallets have been the mainstream because they are easy to repair, low in cost, and difficult to slip. It was.
However, wooden pallets may be required to be fumigated for pest control during export, and can be handled more easily, cheaper and more reusable to avoid such problems. Corrugated pallets with sufficient strength have been attracting attention.
As such a cardboard pallet, for example,
(1) A core made of multi-layered cardboard is provided, and a circumferential surface along the longitudinal direction of the core is covered with a cardboard plate, and a cardboard base sheet is placed on the upper surface or both upper and lower surfaces of the encapsulated cores arranged in parallel at intervals. Cardboard pallet,
(2) Corrugated cardboard pallet (1) above, in which multiple base sheets are attached to the top surface of the encapsulating core, and the base sheets are stacked so that the vertical cores in each base sheet are arranged at right angles in the vertical direction. (See Patent Document 1).
This corrugated cardboard pallet is intended to make the girder member (the above-mentioned enveloping core) and the deck board (the above-mentioned base sheet) strong and to improve the durability.

Japanese Utility Model Publication No. 5-34133 (Claims 1 and 2, FIGS. 1 to 5)

  However, in general, the pallet is used repeatedly, so that the pallet is not limited to the one of the above-mentioned Patent Document 1, and when the girder member and the deck board are somewhat tightened, the cardboard gradually becomes fatigued due to repeated use, and the load of the load causes There are problems such that the deck board is bent somewhat, the load is tilted, the conveyance becomes difficult, and the risk of collapse of the load increases.

  In the present invention, a plurality of girder members are provided on the lower surface of a cardboard deck board, and a fork insertion space is provided between the girder members to form a pallet main body. The frame body is fixed, and the side wall made of corrugated cardboard is detachably erected on the inner periphery of the frame body, thereby supporting the side wall with the frame body, surrounding the load with the side wall, and preventing the inclination of the load In this way, the above problem is solved.

In short, the present invention provides a plurality of girders on the lower surface of a cardboard deck board, and provides a fork insertion space between the girders to form a pallet main body.
Since the corrugated cardboard side walls are erected around the pallet, the pallet can be transported easily by surrounding the load with the side wall to prevent the load from tilting, and the collapse of the pallet can be avoided. Generation can be prevented.
In addition, since the side wall is provided on the inner periphery of the frame fixed on the pallet body, by supporting the side wall with the frame, sufficient strength can be secured and the load can be reliably supported.
Furthermore, since the side wall is made detachable, by loading the frame body with the side wall removed, and then mounting the side wall, the side wall does not interfere with the load loading operation, and the side wall is removed. It is only necessary to unload and work can be carried out smoothly.

  A cardboard hanging part is provided around the top of the corrugated cardboard to form a lid, and the lid is fitted on the upper end of the side wall. By binding the upper end of the side wall with the lid, the side wall becomes more robust, The load can be supported more reliably.

  Since the side wall is disassembled into a plurality of modules and can be stored in the frame, the pallet can be packed compactly after unloading and returned to the loading work site, making it easy to use the pallet repeatedly.

  Since the lid can be fitted to the frame, the module can be prevented from escaping from the frame by attaching the lid to the frame containing the side wall module. It is possible to prevent this from happening, and it is easy to use because it is possible to stack a large number of pallets and return many pallets at a time.

  Since the cardboard reinforcing pad is laminated on the underside of the deck board between the girder members, the amount of deflection of the deck board during loading is small, the stability of the load can be kept well, and it is easier and safer Pallet can be conveyed.

  Since the lower surface of the girder member is bonded to the upper surface of the bottom board made of corrugated cardboard, the girder member is connected even on the lower end side, and stability can be increased and safety can be further improved.

  Because the corrugated cardboard reinforcement pad is laminated on the top of the bottom board between the girder members, the overall strength can be greatly improved, the stability can be further improved, etc. It is very big.

It is a schematic perspective view of the pallet which concerns on this invention. It is a schematic exploded view of the pallet of FIG. It is a schematic perspective view of the state which accommodated the side wall of the pallet of FIG. 1 in the frame. It is a schematic exploded view of the pallet of FIG.

Examples of the pallet of the present invention will be described in detail below.
As shown in FIGS. 1 to 4, the pallet of the present invention has a plurality of beam members 2, 2a, etc. disposed on the lower surface of a cardboard deck board 1, and a fork inserted between the beam members 2, 2a,. .. Are provided on the bottom surface of the deck board 1 and a corrugated cardboard reinforcing pad 5 is laminated between the girder members 2, 2 a.
Further, the lower surface of the girder members 2, 2 a... Is bonded to the upper surface of the bottom board 6 made of corrugated cardboard, and the reinforcing pad 7 made of corrugated cardboard is laminated between the girder members 2, 2 a. Yes.

  A cardboard frame body 8 is fixed on the pallet body 4 (the upper surface of the deck board 1), and a cardboard side wall 9 is detachably installed on the inner periphery of the frame body 8. A lid 10 is fitted on the upper end.

  The lid body 10 is provided with a corrugated board hanging portion 12 around the corrugated board top plate 11, and the lid body 10 is appropriately set with vertical and horizontal dimensions as shown in FIGS. 10 is removed from the side wall 9 and can be fitted to the frame 8.

The deck board 1 may be formed by cutting a single corrugated cardboard sheet to an appropriate size, or a plurality of cut corrugated cardboard sheets may be stacked to form the deck board 1.
In addition, when forming the deck board 1 with one cardboard sheet, from the viewpoint of ensuring strength, it is preferable to use a double-sided cardboard sheet or a double-sided cardboard sheet, and when stacking a plurality of cardboard sheets, Double-sided corrugated cardboard sheets may be used, but it is preferable that the flute orientations of the upper and lower layers are orthogonal to each other by making the flute directions of the cores of the corrugated cardboard sheets of each layer different.

The girder members 2, 2a, etc. may be formed by laminating a plurality of corrugated cardboard sheets cut to an appropriate size, or other cardboard sheets may be wound around the laminated body to form a girder member. A cardboard sheet may be wound around the expanded polystyrene to form a girder member.
When a plurality of cardboard sheets are stacked, the width direction of the corrugated cardboard sheet can be put into practical use with the vertical direction of the beam members 2, 2a... And the thickness direction of the cardboard sheet set as the left and right direction of the beam members 2, 2a. Ensure strength.

  The frame 8 is formed in a bowl shape by a corrugated cardboard sheet, and the side wall 9 is assembled from a plurality of modules 13, 13a... As shown in FIG. By making it bendable, as shown in FIG. 4, the modules 13, 13 a... Disassembled from the side wall 9 can be stored in the frame body 8.

  When the pallet of the present invention is used, a load is loaded in the frame 8 with the lid 10 and the side wall 9 removed (the state shown in the lowermost stage in FIG. 2), and then the side wall 9 and the lid 10 are placed. 1 and is transported in the state shown in FIG. 1. When unloading, the lid 10 and the side wall 9 are removed, and after unloading, the side wall 9 is placed in the frame 8 as shown in FIG. The modules 13 and 13a are disassembled, the lid body 10 is fitted on the frame body 8, and the entire pallet is compactly assembled and returned to the loading site as shown in FIG.
