Was dropped and stored in 350 kg. When stored up to the predetermined amount,
The upper tray 8 is automatically covered, and the elastic member 12 made of rubber is hooked on the hook 13 provided on the body 4. In this way, four boxes were created. The four boxes thus prepared were stacked in two stages on a truck bed by a forklift, traveled about 300 km, and transported. As a result, no deformation or collapse was observed in any of the four boxes. Next, a discharge test of the contents was performed using one of the four boxes subjected to the transport test. First, carry it to the position just above the raw material receiving port with a forklift with a full rotation fork,
The forklift was stopped. Next, the box was raised to a height of 1 m, the door closing part 7 of the opening / closing section 5 was removed, and the fork was slowly rotated so that the contents were discharged from the opening / closing opening of the body, and the box was tilted. Discharging of the contents started when the tilt angle was 23 °, and the discharge was completed when the tilt angle was 45 °. Furthermore, using three of the four boxes tested for transportation,
A durability test was performed. When three boxes were stacked in three stages and allowed to stand for three months, the boxes had good durability without deformation or crushing. A discharge test of the contents of these three boxes was performed in the same manner as described above. As a result, all of the three boxes were discharged at the same angle as above. When the disassembled box is disassembled after the discharge of the contents is completed, it takes an average of one minute to disassemble and make a small box. It took 1.5 minutes on average to remove each part and assemble the box.
