Description

Carriage system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyance railcar system, and more particularly, to a conveyance railcar system that is provided on a rail for a conveyance railcar or a rail for a conveyance railcar, To a traction bogie system capable of checking the condition of a power supply cable.

Overhead shuttles (OHS) and overhead hoist transport (OHT) systems are installed in large hospitals, semiconductor and flat panel display production plants where there are many small objects to be transported.

Such a conveying and boggling system may include a conveying bogie for conveying an object and a rail for a conveying bogie which is provided on the ceiling for allowing the conveying bogie to run, and which includes a running rail and a branching rail branched from the running rail.

For example, in a case where a conveyance truck system is installed in a semiconductor or display flat panel production line, a running rail and a branch rail branched from a running rail are installed in a ceiling space in a clean room. The conveyance truck travels between the conveyance ports The object is transported while traveling along the rails and the branch rails.

Here, the running rails and the branch rails are supported in the ceiling space of the clean room by pillars or the like. The running and branch rails also include the rail body and the feed rail.

Meanwhile, such a conveyance system is a system for conveying objects along a rail which is several kilometers long, that is, a rail for a conveyance truck, so that there are problems when the system is installed or operated after the installation Possession is high.

First, in the case of a rail for a conveyance truck constituting a conveyance truck system, it is installed on the ground by connecting a straight unit member having a length of about 3 to 4 m and a curved unit member with a fastener. In this case, a manufacturing error of the unit members, Or a loosening phenomenon of the fastening portion, a step may be generated in a part of the rail for the conveyance truck, in particular, a connecting portion to which the unit members are connected. If a step is generated at the connecting portion, the conveying carriage may be severely shaken at the stepped portion during running, and may cause marks or damage to the wheels due to the stepped surfaces. Therefore, it is necessary to check in advance whether there is a step on the connecting portion.

Second, if there is foreign matter (or dust) on the rail for the transporting truck, or if the rail for the transporting truck is dirty, it may adversely affect the traveling of the transporting truck, and may also transfer foreign matter and contaminate other areas. Therefore, it is necessary to check in advance whether or not there is any foreign substance in the rail for the conveyance truck.

Thirdly, when a part of the non-contact power supply cable installed on the rail for the transportation truck is damaged or the flow of the current is not good for driving the transportation truck, heat may be generated and a fire may be generated in some cases. Therefore, it is necessary to continuously check the state of the non-contact power supply cable, that is, the temperature of the non-contact power supply cable.

Fourth, the noncontact power supply cable and the power supply and reception device must be maintained with a certain gap between the noncontact power supply cable and the power supply and reception device when the conveyance vehicle travels. If the noncontact power supply cable is deformed, Contact power supply cable may be damaged, the position of the non-contact power supply cable should not be deformed. Therefore, it is necessary to constantly check the gap between the noncontact power supply cable and the power supply.

In the case of operating the transfer lending system, problems other than the above 4 items may occur. However, in the case of the above-mentioned four items, there have been many cases in which the accident occurred before and after the accident. As a result, it is necessary to take action in the event of an increased accident, resulting in a lot of loss.

Of course, it is of course possible for the inspector to go directly to the ceiling and visually inspect the entire length of the trailer bogie, but since it is difficult to periodically or continuously inspect the trailer bogie rail for several kilometers (km) The state of the noncontact power supply cable installed on the rail for the trailer brakes or the rail for the trailer brakes has not been checked and the measures have been taken after the occurrence of the accident as described above, Development is necessary.
