段ボール箱1は、外形が直方体または立方体であるものが好ましいが、それらに限定されるものではなく、外形が円柱形状のもの、角柱形状のものなどでもよい。
<Procedure 1>
In the procedure 1, as shown in FIG. 1, the cover of the cardboard box 1 serving as the outer container is opened and opened (opening 2).
The cardboard box 1 has a bottom surface 11, four side surfaces 21 to 24, and four lids 31 to 34 that are previously closed with an adhesive tape or the like. Note that the bottom surface 11 before closing is the same as the four lids 31 to 34.
In the procedure 1, the four lids 31 to 34 are expanded so as to be substantially parallel to the bottom surface 11.
A plastic inner bag 40 used in the following procedure 2 is shown above the cardboard box 1.
The size of the cardboard box 1 is not particularly limited. For example, a cardboard box having a length of 400 to 500 mm, a width of 250 to 350 mm, and a height of 350 to 450 mm can be used.
The cardboard box 1 preferably has a rectangular parallelepiped shape or a cube shape, but is not limited thereto, and may have a cylindrical shape or a prismatic shape.

<手順2、2'>
手順2では、図2(a)に示すとおり、開口部2からプラスチック製の内袋40を入れて、内袋40の袋口41を段ボール箱1の開口部2の4枚の蓋31〜34に沿って外側に拡げる。
内袋40の大きさ(容積)は、段ボール箱1の内部の底面11と4つの側面21〜24に接触した状態で配置できるものが好ましい。
<Procedure 2, 2 '>
In step 2, as shown in FIG. 2A, a plastic inner bag 40 is inserted from the opening 2, and the bag mouth 41 of the inner bag 40 is inserted into the four lids 31 to 34 of the opening 2 of the cardboard box 1. Expand outward along the line.
The size (volume) of the inner bag 40 is preferably one that can be disposed in contact with the bottom surface 11 and the four side surfaces 21 to 24 inside the cardboard box 1.

手順2'では、その前段階(図1の手順1)において、図2(b)に示すように段ボール箱1の4枚の蓋31〜34が4つの側面21〜24と同一面を形成するように保持された状態にする。
段ボール箱1が未使用の場合には、図2(b)に示す状態にすることは容易であるが、必要があれば、蓋31〜34が4つの側面21〜24の境界部分に柔軟性のある枠体、ゴムバンドなどを嵌め込んで図2(b)に示す状態にする。
手順3'では、図2(b)に示す状態の段ボール箱1の開口部2からプラスチック製の内袋40を入れて、内袋40の袋口41を段ボール箱1の開口部2の4枚の蓋31〜34に引っかけるようにして外側に折り曲げる。
In the procedure 2 ′, in the previous stage (procedure 1 in FIG. 1), the four lids 31 to 34 of the cardboard box 1 form the same surface as the four side surfaces 21 to 24 as shown in FIG. So that it is held.
When the cardboard box 1 is not used, it is easy to obtain the state shown in FIG. 2B, but if necessary, the lids 31 to 34 are flexible at the boundary portions of the four side surfaces 21 to 24. A frame, a rubber band or the like is fitted into the state shown in FIG.
In step 3 ′, a plastic inner bag 40 is inserted from the opening 2 of the cardboard box 1 in the state shown in FIG. 2B, and the bag mouth 41 of the inner bag 40 is inserted into the four openings 2 of the cardboard box 1. Folded outward so as to be hooked on the lids 31-34.

At this time, a method of applying vibration in the vertical direction to the cardboard box 1 is preferable, and a method of applying vibration in the vertical direction and the horizontal direction is more preferable. Note that the bulk density cannot be sufficiently increased by the method of applying vibration only in the left-right direction.
When the resin-attached long fiber pellets 50 are packed in this manner while applying vibration to the cardboard box 1 in a predetermined direction, the bulk of the resin-attached long fiber pellets 50 is as shown in FIGS. 3 (a) to 3 (b). Since the density can be increased quickly and the apparent amount can be reduced, the packing time can be shortened and the amount of the resin-attached long fiber pellets 50 can be increased (the bulk density after the storage is increased). become able to.
As described above, a method of packing the resin-attached long fiber pellets 50 while applying vibration may be used, or a method of applying vibration after the resin-attached long fiber pellets 50 are packed may be used.

比較例1
手順1、2は実施例1と同様に実施したあと、次のように手順3を実施した。
図3(a)に示すように袋を入れた段ボール箱1を振動機100の加振テーブル101の上に置き、段ボール箱1に振動を加えながら、実施例1と同じ樹脂含浸炭素長繊維ペレットを合計で約10gkg連続投入した。
振動機100は、振動方向が左右方向のみ、振動幅が±25mmの範囲、周波数が3Hzで運転した。
振動機100による振動運転を約60秒間実施したが、図3(a)示す状態からほとんど変化がなかった(かさ密度の変化は0.16g/cm3から0.17g/cm3)。
Comparative Example 1
Procedures 1 and 2 were carried out in the same manner as in Example 1, and then procedure 3 was carried out as follows.
As shown in FIG. 3 (a), a cardboard box 1 containing a bag is placed on a vibration table 101 of a vibrator 100, and the same resin-impregnated carbon long fiber pellet as in Example 1 is applied while vibration is applied to the cardboard box 1. About 10 gkg in total.
The vibrator 100 was operated with a vibration direction only in the left-right direction, a vibration width in a range of ± 25 mm, and a frequency of 3 Hz.
Although the vibration operation by the vibrator 100 was performed for about 60 seconds, there was almost no change from the state shown in FIG. 3A (change in bulk density from 0.16 g / cm 3 to 0.17 g / cm 3 ).

本発明の棒状成形体の収容方法は、プラスチック、紙、木などの比重の軽い材料をベースとする棒状成形体を容器内に隙間なく詰め込むことができ、しかも作業時間を短縮できるため、各種製造ラインの最終段階における容器への詰め込みおよび容器の梱包作業に利用することができる。   The method for accommodating the rod-shaped molded body of the present invention can pack the rod-shaped molded body based on a material with a light specific gravity such as plastic, paper, wood, etc. without any gaps, and can shorten the working time, so that various manufacturing methods are possible. It can be used for packing the container and packing the container at the final stage of the line.
