  Hereinafter, a packing and hanging tool of the present invention will be described based on an embodiment shown in the drawings.

  The packing and hanging tool 1 of the present invention illustrated in FIGS. 1 to 3 is used when a load 15 loaded on a pallet 14 (hereinafter, sometimes referred to as a load 15 on the pallet 14) is loaded by using a crane. . The luggage 15 is various, for example, a powdered body or a granular body packed in a bag. These packages 15 are stacked on the pallet 14 in a plurality of stages. In some cases, another pallet 14 loaded with the load 15 may be loaded on the load 15 loaded on the pallet 14. Using a crane, the load 15 on the pallet 14 is transferred from the quay to a predetermined place such as a ship or a transport vehicle, or from a warehouse to a predetermined place such as a transport vehicle, and is conveyed to a final destination for unloading. .

  The packing and hanging tool 1 has a sheet-like bottom portion 2, a sheet-like side portion 3, and an engaging portion 4. The sheet-like side part 3 is joined to the sheet-like bottom part 2, and the engaging part 4 is joined to the sheet-like side part 3, and these three members are integrated. The respective members are joined by, for example, suturing, but are not limited to suturing as long as they can be integrated.

  In this embodiment, the sheet-like bottom 2 is square in a plan view, and each sheet-like side 3 is joined to four sides of the sheet-like bottom 2. Most of the area of the sheet-like bottom 2 is a mounting area 5 on which the pallet 14 is mounted. Note that the form shown in FIG. 1 can also be obtained by overlapping and joining two rectangular sheets in a cross shape. In this case, since the sheet-shaped bottom portion 2 has a double sheet, the sheet-shaped bottom portion 2 is thicker than the sheet-shaped side portion 3 and the reinforcing effect is enhanced. The shape of the sheet-shaped bottom portion 2 in plan view is not limited to a square, but may be a polygonal shape such as a triangle or more, a circle, an ellipse, or the like. However, the shape may be the same as the bottom shape of the pallet 14 to be placed. desirable. For example, the sheet-like bottom portion 2 has a shape similar to the bottom surface of the pallet 14 to be placed, and has an area slightly larger than the bottom surface of the pallet 14 (about 1.05 to 1.1 times the bottom surface). You. As a result, the pallet 14 and the load 15 can be accommodated inside the mount range 5 without excessively widening the mounting range 5 with respect to the pallet 14 and the load 15.

  The sheet-like side portions 3 extend radially in at least three directions around the sheet-like bottom portion 2 in plan view. In this embodiment, four sheet-like side portions 3 which are rectangular in a plan view extend radially in four directions, and the short side of the sheet-like side portion 3 is set to the same length as one side of the sheet-like bottom portion 2. Have been. The extension length (the length of the long side in this embodiment) of each sheet-like side portion 3 is set based on the height of the load 15 on the pallet 14 and the like. It is preferable that the respective sheet-like side portions 3 have basically the same specifications and are arranged at equal intervals in the circumferential direction with respect to the sheet-like bottom portion 2.

  An appropriate material and thickness are selected so that the sheet-shaped bottom portion 2 and the sheet-shaped side portions 3 have strength enough to withstand the weight of the pallet 14 and the load 15, respectively. The sheet-shaped bottom portion 2 and the sheet-shaped side portion 3 can be different from each other in the material and the thickness, or can be the same. The sheet-shaped bottom portion 2 is a member that has a greater overload when hanging the load 15 on the pallet 14 than the individual sheet-shaped side portions 3 and that the pallet 14 contacts. Therefore, it is desirable that the sheet-like bottom portion 2 has a higher strength specification than the respective sheet-like side portions 3. As the material of the sheet-shaped bottom portion 2 and the sheet-shaped side portion 3, various synthetic resins (for example, polyethylene), natural fibers, and the like can be used, and a simple sheet or a knitted sheet can be used.

  The sheet-shaped side portion 3 may be made of different materials and characteristics on the front side and the back side (the side facing the pallet 14 and the baggage 15). For example, the back side is a specification that completely covers the suspended load and has a strength against the load's own weight, and the front side is a specification that protects the sheet and the suspended load on the back side from damage due to contact with the outside (for example, Specifications that do not substantially bear the load). The sheet-like bottom part 2 can be made in the same manner.

  In this embodiment, the sheet-like bottom part 2 and the sheet-like side part 3 are provided with belts 6 at their respective peripheral edges. The belt 6 has a higher tensile strength than portions of the sheet-shaped bottom portion 2 and the sheet-shaped side portion 3 other than the belt 6. The belt 6 is formed of, for example, the same material as a known sling belt. Since the belt 6 functions as a reinforcing material for the sheet-like bottom portion 2 and the sheet-like side portion 3, it is desirable to provide the belt 6 in order to improve the durability of the packing and hanging tool 1.

  As illustrated in FIGS. 4 and 5, the engagement portion 4 is engaged with a connection fitting (hanging tool) 10 via a hanging tool (a master ring 12 and a wire rope 20) suspended from a crane. In this embodiment, two annular engaging portions 4 are provided at the leading end portions of the respective sheet-shaped side portions 3 in the extending direction at intervals in the width direction of the sheet-shaped side portions 3. Specifically, the engaging portions 4 are joined to the belts 6 at the peripheral edges at both ends in the width direction of each sheet-shaped side portion 3. The distance H between the respective engaging portions 4 and the sheet-like bottom portion 2 is set to be equal to or greater than the total height H1 of the pallet 14 and the load 15 placed in the placing range 5. An appropriate material and thickness are selected so that the engaging portion 4 also has strength enough to withstand the weight of the pallet 14 and the load 15. The engaging portion 4 and the belt 6 can be made of the same material.

  In this embodiment, the packing and hanging tool 1 further includes two types of connecting members (8, 9) capable of connecting and disconnecting the adjacent sheet-like side portions 3 when the load 15 on the pallet 14 is packed. )have. One type of connecting member is a tightening belt 8 and the other type of connecting member is a cord 9 joined to each sheet-like side portion 3.

  The packing belt 8 is inserted through the annular through-holes 7 provided on the respective sheet-like side portions 3. The pass-through portions 7 are joined to the belts 6 at the peripheral edge at one end in the width direction of each sheet-like side portion 3. A plurality of the through portions 7 can be provided for each sheet-like side portion 3 instead of one. The load tightening belts 8 inserted through the respective through portions 7 are in an annular state, and appropriately tighten the loads 15 on the pallet 14 from the outer peripheral side. Various synthetic resins, natural fibers, and the like can be used as the material of the packing belt 8.

  The cord 9 is arranged on the distal end side in the extending direction of the sheet-like side portion 3 with respect to the through portion 7. Strings 9 are joined to the belts 6 at the peripheral edges at both ends in the width direction of each sheet-shaped side portion 3. In this embodiment, two cords 9 are provided in each sheet-like side portion 3 at intervals in the extending direction of the sheet-like side portion 3. Since it is not expected that the string 9 bears an excessive force, a general resin or natural fiber may be used.

  Hereinafter, a cargo handling method using the packing and hanging tool 1 will be described by taking as an example a case where a cargo 15 of a pallet 14 is transferred from a quay to a ship and transported to a final destination.

  First, as illustrated in FIG. 1, the packing and hanging tool 1 is placed on a quay, and the sheet-like bottom 2 and each sheet-like side 3 are spread flat. Next, as illustrated in FIG. 2, a forklift 16 holding a pallet 14 on which the load 15 is loaded is run on the deployed packing and hanging tool 1, and as illustrated in FIG. Is placed in the placement range 5.

  More specifically, the pallet 14 is placed in the placing range 5 so that the peripheral edge of the pallet 14 is attached to the peripheral edge of the sheet-like bottom 2. When the direction of the forklift 16 is changed on the packing and hanging tool 1, the packing and hanging tool 1 (mainly the sheet-like side portion 3) is rubbed and easily worn, so that any one of the sheet-like side portions 3 is worn. The forklift 16 may be run in the extending direction.

  Next, as illustrated in FIG. 4, each sheet-like side portion 3 is raised so as to be along the side surface of the load 15. In FIG. 4, the cargo 15 of the pallet 14 is described as a rectangular parallelepiped with a two-dot chain line. In this state, the cords 9 at the opposing positions of the adjacent sheet-shaped side portions 3 are connected to each other to connect the sheet-shaped side portions 3 to each other. Thereby, it is possible to prevent each of the sheet-like side portions 3 that have risen from falling down. In addition, the loading belts 8 are inserted through the respective passing portions 7 and are appropriately tightened to stabilize the loads 15 on the pallet 14 from the outer peripheral side of the respective sheet-like side portions 3.

  Since the separation distance H of the engaging portions 4 attached to the respective sheet-like side portions 3 from the sheet-like bottom portion 2 is set to be equal to or greater than the total height H1 of the pallet 14 and the load 15, the pallet is removed by this operation. Substantially the entire side surfaces of the package 14 and the load 15 are covered by the sheet-shaped side portions 4. The upper limit of the separation distance H is, for example, about 1.5 times the total height H1.

  Next, as illustrated in FIG. 5, the connecting fittings 10 of the crane are engaged with the respective engaging portions 4. In this embodiment, a hook 13 is connected to a lower end of a wire rope 11 of a crane. A wire rope 20 having a connection fitting 10 at the lower end is connected to the hook 13 via a master ring 12. As illustrated in FIG. 4, since the respective engaging portions 4 protrude from the upper ends of the respective sheet-like side portions 3 maintained in the upright state, the connecting fittings are provided on the respective engaging portions 4. The operation of engaging the engaging member 10 can be performed relatively easily.

  Next, as shown in FIG. 6, the load 15 of the pallet 14 is lifted by the crane using the packing and hanging tool 1, and is moved from the quay 17 toward a predetermined storage area 19 on the ship 18. Next, as illustrated in FIG. 7, the load 15 of the pallet 14 is moved downward at a position above the storage 19, and the pallet 14 is landed on the storage 19 via the sheet-like bottom 2.

  Next, the engagement between the respective engaging portions 4 and the connection fittings 10 is released, and the cargo 15 on the pallet 14 is transported to the transport destination while being covered with the packing and hanging tool 1. At the transport destination, the connecting fittings 10 of the crane are again engaged with the engaging portions 4, respectively, and the load 15 of the pallet 14 is lifted by the crane using the packing and lifting tool 1, and the load 15 of the pallet 14 is transported to the final destination. Land.

  Next, the knots of the respective cords 9 are unwound, the binding belts 8 are removed, and the connection of the respective sheet-like side portions 3 is released. By this operation, the respective sheet-like side portions 3 covering the cargo 15 of the pallet 14 are developed flat and brought into the state illustrated in FIG. Thereafter, the cargo 15 on the pallet 14 is carried out from the flat and unfolded packing and hanging tool 1 using a forklift 16. That is, a step opposite to the step of loading the load 15 on the pallet 14 illustrated in FIG. 2 is performed.

  In cargo handling using a crane, the cargo 15 on the pallet 14 may be collapsed. However, in the present invention, since almost all of the side surfaces of the pallet 14 and the cargo 15 are covered with the sheet side portions 3 during cargo handling. The load 15 can be suppressed within the range covered by the sheet-like side portions 3. That is, in the packing and hanging tool 1 suspended by the crane, an appropriate tension is applied to each of the sheet-shaped side portions 3. The movement is regulated to prevent the collapse of the load.

  The use of the packing and hanging tool 1 eliminates the need for a special operation for preventing collapse of the load such as winding a conventional stretch film. In addition, since the load 15 on the pallet 14 can be loaded and unloaded on the flattened packing and hanging tool 1, it is possible to avoid a reduction in work efficiency during loading. In addition, the packing and hanging tool 1 has a foldable structure, and can be reduced in weight by using a high-strength material having a small specific gravity for the sheet-like bottom portion 2 and the sheet-like side portion 3. Therefore, storage and transportation are easy. In order to more reliably avoid the collapse of the load 15, the conventional packing collapse tool such as a stretch film may be used in combination with the packing and hanging tool 1. The load 15 packed by the packing and hoisting tool 1 has a stable load shape that is easily suspended by a crane. For this reason, if a plurality of loads 15 to be loaded / moved by the crane are packed in advance by the packing / lifting tool 1, the efficiency of the loading / moving operation is improved. Since the packing operation is easy, a new load 15 can be separately packed even during the loading operation. Therefore, the overall efficiency of the cargo handling operation can be improved.

  In this embodiment, a packing and hanging tool 1 is used in which a sheet-like side portion 3 extends from four sides of a square-like sheet-like bottom portion 2 with respect to a pallet 14 having a square bottom surface. Therefore, it is advantageous to more stably pack the load 15 on the pallet 14 by the packing and hanging tool 1 and to prevent the collapse of the load at the time of loading by the crane.
