Then, the suspension members 3 and 3 are respectively disposed on the beam members 8 and 8 installed between the side frames 7 and 7 so that the packaged part W can be suspended.

When packing the packaged parts W with the packing material 1, the packaged parts W are alternately suspended from the two directions in which the positioning members 4 and 4 are positioned with respect to the suspension members 3 and 3, and the second frame portion. W2 is fitted into the housing grooves 10 and 10. Moreover, the lower end part 53 of the 1st frame part W1 of the to-be-packaged part W is inserted in the accommodation recessed part 12 of a positioning member. When the parts to be packed W are placed in this way, the positioning members 4 and 4 that face each other are arranged at an interval larger than the extending length of the second frame portion W2 in plan view, and thus the overhang portion W3. Is located below the base end of the adjacent second frame W2.
When the packaged parts W, W,... Are fitted into the housing grooves 10, 10,... Of all the suspension members 3, 3, and the housing recesses 12 of the positioning member 4, the second packaged parts W suspended. A pressing member 5 is fitted from the upper side to the central portion in the extending direction of the frame portion W2, and the hat steel 9 shown in FIG. The end of the side is fixed to the vertical member of the side frame 7 with a fixture 20 made of bolts and nuts, and packing of the packaged part W is completed.
In this way, the part W to be packed is packed with the packing material 1 to complete a package A as shown in FIG. 5, for example.

  As described above, according to the packaging body 1 of the present embodiment, the parts to be packed W are held by the suspension members 3 and 3, and the lower end portion 53 of the first frame portion W <b> 1 is held in this state of the positioning member 4. It is held by the housing recess 12. Therefore, it is possible to pack a plurality of parts to be packed W simply and appropriately in a state where they are suspended in a standing posture, and it is possible to pack while suppressing the swing of the parts to be packed W. Therefore, the efficiency of packing and unpacking work is increased, and the packaged part W of the package A is reliably protected, while the packaged part W is prevented from swinging and can be easily transported. .

Supported along the upper surface shape of the second frame W 2 at a position shifted from the arrangement position of the suspension members 3 and 3. Thus, the second frame portion W2 is held from above. Therefore, by holding the member to be packed W from three different directions by the suspension members 3 and 3 and the pressing member 5, the swing of the part to be packed W in the extending direction of the receiving groove 10 or the receiving groove 16 is effective. The packaged part W can be more reliably held and the effect is achieved.

Further, the overhanging portion W3 at the tip of the second frame portion W2 is adjacent to this by suspending the packaged part W alternately from two directions orthogonal to the extending direction of the suspension member 3. Since the dimension of the placed part W to be packaged W positioned below the base end of the second frame part W2 can be absorbed, the part to be packaged W having such a projecting part W3 is used as the packaging part. There is an effect that the pitch between W, W... Can be reduced as much as possible and packing can be performed efficiently.

  In addition, in said embodiment, although it is set as the structure which fitted the to-be-packaged part W from the upper direction of the suspension member 3, it was set as the structure, it is not restricted to this, The accommodation groove part 10 of the suspension member 3 The part W to be packaged may be suspended from the lower part of the suspension member 3 by being fitted in the receiving groove part 10 with facing downward.

Further, the housing groove portion 10 is formed orthogonal to the extending direction of the hanging member 3, but is not limited thereto, and has an angle other than 90 degrees with respect to the extending direction of the hanging member 3. It may be cut out as it is made.
Further, the bottom surface 10s of the housing groove portion 10 is formed along the bottom surface shape of the base end portion of the second frame portion W2, but the bottom surface 10s along the bottom surface shape of the base end side of the second frame portion W2. And the same number of accommodating groove portions 10 having bottom surfaces 10s along the shape of the bottom surface of the distal end side of the second frame portion W2 are formed in the extending direction of the suspension member 3. Also good.
By forming the shape of the housing groove 10 in this way, the packed parts W can be brought into close contact with each other and fitted, and the holding of the packed parts W can be further stabilized.

In the present embodiment, the packaged component W is suspended from both sides of the suspension members 3 and 3 in order to efficiently pack the packaged component W having the overhanging portion W3 at the tip of the second frame W2. However, as long as it does not have a portion projecting laterally with respect to the extending direction of the packaged part W, the packaged part W is suspended from one direction with respect to the suspension members 3 and 3. It may be configured to be lowered. In this case, the positioning member 4 only needs to be arranged on one side with respect to the suspension members 3 and 3.
Even in the case of such a configuration, the same operational effects as the operational effects of the packaging material and the packaging body of the above-described embodiment except that the part to be packaged W is suspended from the two directions with respect to the suspension member 3. Play.
