Movable body system

Abstract

A first object is to provide a movable body system adapted to be guided along a guide rail, wherein power supply devices are disposed in suitable positions. A second object is to provide a movable body system adapted to move along a guide rail, wherein the movable body system has primary and secondary transformers suitable for the system. To achieve the first object, the system is characterized in that power supply elements are disposed on a guide rail, some on a member supported by the guide rail and on a rail bracket supporting the guide rail. To achieve the second object, the system is characterized it that when projected in the direction of travel of the movable body, the outer end of the primary transformer on the movably body side is positioned closer to the movably body than the outer end of the secondary transformer.

Description

technical field [0001] The invention relates to a moving body system which is guided to move by a guide rail, in particular, the invention relates to a power supply aspect of the moving body system. Background technique [0002] For example, JP-A-57-121568 and JP-A-5-294568 disclose conventional mobile body systems using guide rails. [0003] In the prior art described in JP-A-57-121568, an inverter and a charger are loaded on the primary side of a linear motor on a counterweight. In this charger, when the counterweight is stopped at the bottom position, the straddle connector is connected to the main power system, thereby realizing power supply. [0004] In addition, in the prior art described in JP-A-5-294568, when the elevator car reaches the stop floor, power can be supplied to the elevator car without contact. [0005] In addition, the field of mobile body systems using guide rails is not the same. In the prior art described in JP-A-11-285156 and JP-A-8-37121, electri...

Problems solved by technology

[0006] However, the prior art disclosed in JP-A-57-121568 and JP-A-5-294568 does not consider the specific location of the power supply device at all.

[0007] In addition, the prior art described in JP-A-11-285156 and JP-A-8-37121 has a structure with a high transformer coupling ratio.

However, it does not take into account the interleaving of the primary transformer and the secondary transformer that will inevitably occur when it is applied to a moving body that moves along a guide rail such as an elevator.
