Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical chain conveyor device that vertically conveys a chain that circulates, and more particularly, to a conveyor for supporting a conveyor container that stores an object to be conveyed in the chain. The present invention relates to a vertical chain conveyor device for mounting a supporting member, carrying in a carrying container on the upward moving path of the carried object supporting member, and carrying out the carrying container on the descending moving path of the carried object supporting member.

2. Description of the Related Art A conventional vertical chain conveyor device of this type is provided with one device corresponding to all floors or a large number of floors of a building to be installed. After passing through, it goes down to the target floor and is carried out, while the chain that circulates in proportion to the number of floors of the building and the guide mechanism that guides this become long.
