Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is directed to the use of a transport box having a bottom opening type bottom plate that allows bulk contents such as scrap to be quickly and safely discharged from the transport box. The present invention relates to a transportation method and a transportation box.

<Prior Art> A transport box having an opening-type bottom plate is used to store and transport bulk contents and discharge them onto a truck bed or the like. A transport box with a bottom-opening bottom plate like this has a basic structure in which the bottom plate opens from the box body in a double or single-opening manner when it is lifted, and the bottom plate closes when it is on the ground. When storing bulk contents and transporting them by lifting them with a crane or the like, it is necessary to lock the double-opening bottom plate or the single-opening bottom plate so that they do not open.

For this reason, various proposals have been made for transportation boxes in the past. For example, Japanese Utility Model Application Publication No. 136490/1983 proposes a box body that can be hung so that the tip of the box is inside the shaft attachment part when the box is open. A scrap processing bag is disclosed which is provided with a supported double-opening type (double-opening type) bottom plate, a lever-operated chuck mechanism for the bottom plate, and a sliding roller attached to the tip of the bottom plate.

<Problems to be Solved by the Invention> However, in the bag for scraping processing disclosed in the above-mentioned publication, each time the double-opening bottom plate is opened or closed, the lower end of the hanger is removed via the chuck mechanism by operating a lever on the box body side. It is necessary to lock the locking recess by fitting it into the locking pin attached to the bottom plate, or to release the lock by removing it. In particular, when discharging scrap from a bag, it is not only time-consuming because a lever operation is required at the location where the scrap is to be discharged, but also poses a safety problem as the work may be dangerous depending on the location.

The present invention solves the above-mentioned problems of the prior art, and is particularly effective in removing the lock of the double-opening type or single-opening type bottom plate from the box body in a transport box such as a bag for storing bulk contents such as scraps. The object of the present invention is to provide a method for safely transporting bulk contents using a transport box having an open bottom plate, and a transport box.

Means for Solving the Problems> The method of the present invention for achieving the above-mentioned problems is a transporter having an opening type bottom plate in which the bottom plate closes to the box body in the landing state and opens in the lifted state. In a method for transporting bulk contents using a box, a fixed side engaging member is attached to one of the box main body and a bottom plate, and a movable side engaging member is biased in a direction away from the fixed side engaging member to the other side. loading the bulk cargo contents into the transport box with the bottom plate closed, and resisting the urging force of the movable side engaging tool which is in front of the fixed side engaging tool by more than the hooking height. and mooring the movable side engagement tool to the engagement position with the fixed side engagement tool, and lifting the transport box and lowering the bottom plate relative to the box body in an opening direction corresponding to the hooking height or more. a step of engaging the movable side engaging tool with the fixed side engaging tool; a step of releasing the mooring of the movable side engaging tool with the fixed side engaging tool; and after transporting the i1 transport box to the destination. , a step of moving the movable side engaging tool from the fixed side engaging tool to a hooking height or more and moving the movable side engaging tool from the engaging position to the disengaging position by a biasing force in a landing state, and the transport box. This is a method for transporting bulk contents using a transport box having an opening-type bottom plate, the method comprising the steps of lifting the container, opening the bottom plate relative to the box body, and discharging the bulk contents onto the floor.

Further, in the transport box having an open bottom plate of the present invention, in a transport box having an open bottom plate, the bottom plate closes to the box body in a landing state and opens in a lifted state, in which either one of the box main body and the bottom plate is closed. A fixed side engaging tool is provided on one side, and a movable side engaging tool is provided on the other side, which is biased in a direction away from the fixed side engaging tool, and the movable side engaging tool is moved from the fixed side engaging tool in the landing state. The movable side engaging tool can be held in an engaged or disengaged state with the fixed side engaging tool in a suspended state, and is forward by more than the hooking height and can be moved to an engaged position and a disengaged position. It is characterized by being configured as follows.

<Operation> With the transport box with the bottom-opening bottom plate placed on the floor, the movable side engaging tool, which is biased in the direction away from the fixed side engaging tool, is moved toward the engaged position against the biasing force. After pushing it in, it is moored.

Thereafter, when the transport box is lifted by a crane or the like, the bottom plate is slightly lowered and the movable side engaging tool is engaged with the fixed side engaging tool, so that the transport box can be lifted while the bottom plate is kept in a closed state.

In such a lifting state, both engaging tools can maintain the engaged state, so as soon as the transport box is lifted, the mooring of the movable engaging tool is released and the transport box is continued to be transported to the predetermined position. .

In this way, when the transport box lands on the floor again, the movable side engagement tool has been released from its mooring in advance, so the movable side engagement tool moves in the direction away from the fixed side engagement tool due to the biasing force and returns to the engagement position. will be separated from. After this state is reached, when the transport box is lifted with a crane, etc., the movable side engagement tool passes by the side without being engaged with the fixed side engagement tool, so the bottom plate is opened and the bulk contents are placed on the floor. be discharged.
