Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container car used for transporting parts between factories.

[Prior art and its problems] As a container for transporting goods, the sides are made into a bellows shape that can be expanded and contracted, the left and right sides are divided into foldable parts, and the rear end of the bottom is folded into the rear side. It is known that containers can be attached flexibly, can be stored when the container is not in use, and have improved return efficiency.

However, when this type of container is used as a line-connected container that connects a parts manufacturer and an assembly manufacturer, that is, for transporting parts between factories,
Normally, for convenience of handling, one container only stores parts of the same type, which makes transportation inefficient.Also, because it is wide, it is difficult to move the container in relation to the aisles between lines in an assembly factory. Ta.

On the other hand, if containers are made narrower to make them easier to move, the efficiency of transporting goods between factories or in wide aisles will be reduced, and they will also become unstable and fall sideways at curved or sloping aisles. There is a risk of It was also inconvenient to load and unload containers using forklifts.

In particular, this type of container has a bellows-like or hinged structure on the left and right sides, which makes it weaker than the rear side, causing play and making it difficult to balance the left and right sides. The drawback was that it hindered transportation and movement within the factory.

The present invention was developed to solve the above-mentioned conventional drawbacks, and is strong enough to improve not only storage and return efficiency when the container is not in use, but also transportation efficiency when transporting parts between factories. The purpose is to provide container cars.

[Means for solving problems]

The container car according to the present invention has two rectangular planes.
Consisting of a container with casters, each container has two side parts connected in a planar L shape, and at least one side opposite to the wide side of the two connected sides. , a top portion, and a bottom portion are each foldably attached to one side of the two side portions, and the two containers with casters are connected to the two side portions in the L-shape in plan view. The wide side portions face each other and are separably connected. Further, the side portion opposite to the wide side portion is configured by two or more side portion structural members that are foldably connected.

[Effect]

In the container car according to the present invention, two containers with casters are separably connected, and the flat surface L
Except for the two sides that are connected to each other, each container with casters has the other side plates, top plate, and bottom plate foldable, so the container car can be separated when the container is not in use or when being returned. By folding each container with wheels, the volume can be made significantly smaller than its original volume.

In particular, of the two side parts connected in an L-shape in plan, the side opposite to the wider side is made up of two or more side component members that are foldably connected. With the components folded,
It can be folded against the adjacent narrow side without any problem. Therefore, this side is
The top and bottom parts can be folded to fit either side of the two side parts that are connected in an L-shape in a plane to form an L-shape in a plane, and a container with casters folded in this way can be They can be stacked in parallel to improve storage and transportation efficiency.

In addition, when two containers with casters are connected, the wide sides of the unfolded sides that are connected in an L-shape are faced to each other, so that each container is rectangular in plan. Even if the width of the side is narrow in the direction perpendicular to the wide side,
By connecting, the side width of two containers is increased, and the width of the container car as a whole is increased, so it is stable and there is no risk of it falling sideways. The wide side part located at the top and the side part connected to it serve as a support structure, and despite the folding structure, it has great strength and good left-right balance. Easy to move. Therefore, two containers with casters can be loaded and unloaded by a forklift in a connected state, and can also be transported and moved in a connected state when transporting parts between factories, to a factory entrance, or in a wide aisle.

In addition, the connected container cars can be separated into narrow containers with casters, so they can be moved one by one in the narrow aisles between assembly lines in a factory, and each container with casters can be moved on a flat surface as described above. The two side parts connected in an L-shape function as a support structure, and the ends are in contact with each other, so external forces are applied only in the longitudinal direction of the side parts, so the strength is high.
