Conveying equipment

Abstract

In a conveyance system comprising a movable body supported and guided by a rail device and movable in a fixed path, a feeder line laid along the fixed path, a power receiving means opposed to the feeder line and installed in the movable body, thereby effecting the feeding of power to the movable body by a noncontact power feeding system, main path feeder lines and branching feeder lines are installed overlapping each other on both sides in a branching / joining portion or the like, with the result that the entire arrangement becomes complicated and expensive. In the main path portion of a fixed path, a feeder line is laid along the main path portion, a power receiving means opposed to the feeder line is installed in the movable body to effect the feeding of power to the movable body by a noncontact power feeding system, while in an auxiliary path portion having no feeder line, the feeding of power is effected by a power storing means mounted on the movable body. Thus, the feeding of power is effected by either one of the main and auxiliary path portions, the power receiving means is required only in a single place, the overall arrangement can be made simply and at low cost, and a requirement for an additional installation or the like can be easily coped with.

Description

【Technical field】 [0001] The present invention relates to conveying equipment for supporting and conveying various articles. 【Background technique】 [0002] As a conventional transport facility of this type, there is provided, for example, the configuration shown in JP-A-10-111719. In this conventional configuration, a conveyance trolley is supported and guided by main rails and branch rails. Each rail is composed of a bottom wall, left and right side walls, and an upper wall. The upper wall has a longitudinal slit at the center in the width direction. And, on the side wall of main track and branch track, power supply line is set, and the branch point that is arranged at branch point part is connected with branch track side power supply line with power supply line at the same time. In addition, coupling coils are respectively arranged on the left and right sides of the transport trolley. [0003] According to such a conventional structure, the coupling coil on the right si...

AI Technical Summary

Problems solved by technology

[0004] However, according to the above-mentioned conventional configuration, the main track side power supply line and the branch point power supply line are arranged in an overlapping state on both sides of the branch point, etc., so the overall structure is complicated and expensive.

In addition, since the coupling coils are arranged on the left and right sides of the transport trolley, the overall structure is complicated and the cost is high.

The above-mentioned problems can be solved by mounting a storage battery on the conveying trolley, and the conveying trolley is powered by the battery to run on the main track and the branch track. However, in this case, a large battery must be mounted, and the side of the conveying trolley Large size and heavy weight, and need long enough charging time
