Description

  The present invention relates to a packaging structure for a heavy washing machine such as a drum type washing machine.

  Conventionally, in this type of drum-type washing machine packaging configuration, the first cushioning material made of expanded polystyrene resin and the second cushioning material made of corrugated cardboard having a hollow structure portion are used for the upper four corners and the lower four corners of the product. There has been proposed one that supports a place and holds it in close contact with the outer cover of the cardboard material (see, for example, Patent Document 1).

  FIG. 5 shows an external view of a cushioning material for packaging of a conventional packaging device described in Patent Document 1. As shown in FIG. As shown in FIG. 5, the packaging cushioning material 1 includes a first cushioning material 3 having a load receiving portion 2 that contacts a packaging object and receives a load, and an inner surface shape along the outer surface of the first cushioning material 3. And an outer surface shape along the inner surface of an outer cover (not shown), and includes a second cushioning material 4 that holds the first cushioning material 3 and is inserted in close contact with the outer cover.

  The first buffer material 3 is made of expanded polystyrene resin, and has three wall portions 3a, 3b, and 3c perpendicular to each other, and the inner surfaces of these wall portions 3a, 3b, and 3c serve as the load receiving portion 2. .

  The second cushioning material 4 is made of a corrugated cardboard material and has a rectangular flat plate-like bottom plate portion 5 that is in close contact with the outer bottom surface of the wall portion 3a that receives a load in the vertical direction, and a wall portion 3a of the first cushioning material 3 made of the polystyrene foam resin. 3b, and the hollow structure portions 6 and 7 which are in close contact with the outer surface of 3b.

  The hollow structure portion 6 is formed by bending a rectangular portion 6 a formed integrally with the bottom plate portion 5 on the outer peripheral side from the bottom plate portion 5. Similarly, the hollow structure portion 7 is formed by bending a rectangular portion 7 a formed integrally with the bottom plate portion 5.

  With the configuration described above, the first cushioning material 3 made of foamed polystyrene resin that receives a load is configured to be held by the second cushioning material of the corrugated cardboard material having the hollow structure portion. The first buffer material 3 is reduced in size to reduce the amount of foamed polystyrene resin used.

  However, although the conventional configuration is effective in reducing the amount of the polystyrene foam used, the reduction in the amount of use mainly compensates for the buffer in the left-right direction of the packaged product with the second cushioning material, which is a cardboard material. However, the first cushioning material 3 in the vertical direction of the product, that is, on the bottom plate portion 5 side, must cushion the vertical load and impact by the wall portion 3a that is a foamed polystyrene. Therefore, the packaging size in the vertical direction in the packaging state cannot be reduced.

  The present invention solves the above-mentioned conventional problems, and by reducing the vertical dimension in the packaging state, for example, by increasing the number of stacked stages during container transportation or by increasing the number of stacked warehouses at the time of inventory The aim is to provide a packaging configuration that significantly reduces shipping and inventory costs.

  In order to solve the above-described conventional problems, a packaging machine for a washing machine according to the present invention includes an outer cover of cardboard material covering the periphery of the washing machine, a base of foamed polystyrene material on which the washing machine is placed, and the washing machine A leg rubber part configured to be movable up and down on a bottom surface of the leg part, and a leg rubber part at a lower end of the leg part is formed with a diameter larger than the leg part, and a position corresponding to the leg part of the pedestal is A reinforcing member having a recessed portion with an open upper portion for inserting the leg rubber portion is mounted.

  Thereby, the height dimension of the base of the polystyrene foam material can be reduced, the packaging height dimension can be greatly reduced, and the transportation cost and the inventory cost can be reduced.

  The packaging device of the washing machine of the present invention can reduce the transportation cost and the inventory cost by reducing the vertical dimension in the packaging state.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Further, the present invention is not limited by this embodiment.

(Embodiment 1)
FIG. 1 shows a cross-sectional view of a completed packaging configuration according to Embodiment 1 of the present invention, and FIG. 2 shows an exploded perspective view of the packaging configuration.

  FIG. 3 is a cross-sectional view of the main part of the packaging structure, and FIG. 4 is an operation diagram of the main part of the packaging structure.

  As shown in FIG. 1, a drum-type washing machine (washing machine) 11 is covered with an outer cover 13 made of corrugated cardboard material, and is placed on a base 12 made of polystyrene foam material. Packaged to reduce the impact.

  The pedestal 12 is configured to place the drum type washing machine 11 and cover the outer periphery 15a of the bottom part 15 while restricting the position of the drum type washing machine 11, and to support the leg part 16 of the drum type washing machine 11.

  As described above, the outer cover 13 is covered with the drum type washing machine 11 sandwiched from above and below by the upper cushioning material 14 and the pedestal 12, and the surroundings are wound with a band (not shown) or the like to complete the packaging. The package height dimension at the time of transportation and inventory is H.

  The exploded perspective view of FIG. 2 shows the outline of the packaging operation. First, the drum-type washing machine 11 is placed on the pedestal 12 from above, and the outer cover 13 of cardboard material formed in a substantially cube is covered, and further from above. The upper cushioning material 14 is inserted and stacked on the upper side of the drum-type washing machine 11, the upper cover 18 integrally formed so that the upper side of the outer cover 13 can be folded is folded inward to cover the upper surface, and the band 30 is wound up and down. Wrap around.

  3, the leg portion 16 is configured to project downward from the bottom portion 15 of the drum-type washing machine 11, and has a screw portion 17 that can be adjusted in height by moving the leg portion 16 up and down. The lower part constitutes a leg rubber part 18 having a diameter larger than that of the leg part.

  The pedestal 12 is provided with a reinforcing member 20 having a recessed portion 19 whose upper part is opened so that a large-diameter leg rubber portion 18 below the leg portion 16 is inserted during packaging. The reinforcing member 20 is made of a synthetic resin molded product having a low friction coefficient and relatively high strength, and an upper portion thereof forms a dish-like portion 21 whose cross-sectional shape changes upward in diameter.

  At the time of packaging, the weight of the drum type washing machine 11 is supported by the reinforcing member 20 from the leg rubber portion 18 of the leg portion 16, and the load in the left-right direction is also supported by the concave portion 19.

  4 shows an operation cross section during the packaging operation shown in FIG. 2 before the drum-type washing machine 11 is mounted on the base 12, and the reinforcing member 20 is preliminarily provided in advance. Mounted on the pedestal 12.

  During the packaging operation, a substantially vertical lowering operation is performed as indicated by an arrow A so that the leg portion 16 is attached to the reinforcing member 20 from above.

  In addition, when the drum type washing machine 11 is installed at a place where the drum type washing machine 11 is used, the leg part 16 is adjustable in height so that it can be horizontally installed when the floor surface is not a horizontal surface. 15 Threaded part 17 screwed into female threaded part 22 formed on the bottom surface, Threaded part 17 with lower leg rubber part 18 and Outer part of cap part 23 made of a rubber material having a high friction coefficient and absorbing vibration It is comprised with the disc part 24 of an integral metal material.

  About the washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated.

  Since the area of the vertical load of the drum type washing machine 11 is widely supported by the concave portion 19 of the reinforcing member 20 into which the leg rubber portion 18 of the leg portion 16 is inserted and the dish-like portion 21, the base of the polystyrene foam material is provided. The stress concentration on the base 12 is relieved, and the bottom height of the pedestal 12, that is, the thickness B) (FIG. 3) from the bottom surface of the drum type washing machine 11 to the bottom surface C of the pedestal 12 can be reduced.

  Therefore, the packaging height dimension H in the packaging state shown in FIG. 1 can be greatly reduced, and the effect is particularly great in the packaging of a heavy product such as a drum type washing machine.

  Therefore, by reducing the top and bottom dimensions of the packaging state, for example, the number of stacked stages can be increased during container transportation, and the number of stacked warehouses can be increased during inventory, which can greatly reduce transportation costs and inventory costs. It becomes.

  Further, in the packaging operation shown in the exploded perspective view shown in FIG. 2, when the drum-type washing machine 11 is lowered as shown by the arrow A in FIG. 4, the positions of the leg rubber portion 18 and the concave portion 19 are precisely matched. Even if it occurs in a state where a slight misalignment occurs, at this time, the dish-like portion 21 whose cross-sectional shape changes to a large diameter becomes an insertion guide above the reinforcing member 20, and a slight position is obtained. The leg rubber portion 18 is guided so as to smoothly slide into the concave portion 19 while correcting the shift.

  The rubber cap portion 23 of the leg rubber portion 18 is set to have a high friction coefficient to prevent skidding during product installation operation, and the workability is reduced when it comes into contact with a member having a relatively high friction coefficient such as a foamed polystyrene material. In addition, there is a problem in that the polystyrene foam material is scraped off by a frictional force or partially lost.

  However, in this embodiment, the reinforcing member 20 is made of a synthetic resin molded product having a low coefficient of friction and relatively high strength. Therefore, the above problems are eliminated, and the quality of packaging work is improved and work productivity such as automation is improved. The effect that it can do easily is acquired.

  As described above, the packaging machine of the washing machine according to the present invention can reduce the transportation cost and the inventory cost by reducing the vertical dimension in the packaging state, and thus is limited to the drum type washing machine. It is useful as a packaging structure for heavy products.
