Abstract

PURPOSE:To use one transfer device for two-way use by providing the footboards on respective traveling carts so that they can slide following the curvature of the traveling cart on the curve of a traveling route, and also by covering the upper part of the turning part of a loop-shaped traveling route with a fixed board, so that one side of the traveling route can be made the outward route and the other side thereof the inward route. CONSTITUTION:On the curved route of a traveling rail, a bogie cart frame 54 freely oscillates within an allowable oscillating range in accordance with the radius of curvature, and also footboards mutually slide, so that stable traveling can be achieved. On a plane loop-shaped traveling route, in the turning part of the traveling route where the outward route and inward route are partitioned, the turning part is made horizontal, and also a fixed board 7 is arranged so as to cover the upper part of the footboards situated in the turning part. In this case, the position of the footboards of the traveling route in the turning part is slightly lowered so that persons or articles transferred on the footboards on the outward side or the inward side of the traveling route can be smoothly shifted from the footboards of the traveling carts onto the fixed boards 7, and that the footboards moved to the turning part can successively slide into the underside of the fixed board 7.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a conveying device that uses one traveling path in a planar loop shape as an outgoing path and the other as a returning path. [Prior Art] A conveyor device equipped with a conveyor platform with a flat surface, such as a so-called moving walkway on which a person can ride, uses an endless chain or belt with a required travel distance. A constant-velocity treadle is provided adjacently and integrally, and a sprocket wheel or a pulley on which this chain or belt is hung is driven by a drive device in a so-called concentrated drive system. [Problem to be solved by the invention] According to the concentrated drive method, tension is directly applied to the chain or belt by the drive, so the longer the moving distance, the greater the tension.For this reason, it is permissible in view of the strength and structure of the chain or belt. There is a limit to the length of movement, conventionally up to about 200m per vehicle, and it is impossible to move anything that long.Roughly speaking, chain belts are bent toward the forward and backward directions, that is, in a straight line in the driving direction of the chain belt. It is possible to bend the chain or belt in the vertical direction.For this reason, the return side of the chain or belt is placed below the outgoing side, and the outgoing side below this is placed under the floor.Therefore, only one conveying device can be used. It can only be used for transportation in one direction, either for the outbound or return trip, and requires two conveyance devices to travel in the opposite direction.
Furthermore, it requires space under the floor to store the return side of the transport device, and the underfloor is cut to a depth twice the height of the machine, which increases construction costs. [Means for solving the problem] A plurality of linear motors are distributed along a planar loop-shaped traveling path, and traveling platforms that are distributed and driven by the linear motors are arranged endlessly along the traveling path. Adjacent running bogies are movably connected, and a treadle is provided on each running bogie so that it slides along the curve of the running track following the bending of the running bogie, and at the turn part of the loop-shaped running track. The upper part is covered with a fixed plate, and one of the loop-shaped travel paths is used as an outbound path and the other is used as a return path.

[Embodiment] The conveyance device of the present invention will be described below as an embodiment of a moving walkway.
