つて発生することになる。 Such transport equipment is installed, for example, in hospitals for transporting medical records, or in factories for transporting parts. Nowadays, some objects to be transported, such as wafers, are subject to dust and dirt. For this purpose, recently, conveyance equipment employing ducts has been provided. That is, a rail device is installed in the duct, a connecting portion protruding from the upper end of the self-propelled cart guided by the rail device is passed through a slit formed in the top plate of the duct, and a connecting portion is inserted into the protruding side of the connecting portion. In addition to providing a transport object storage section, a suction device communicating with the inside of the duct is provided to apply suction force to the slit. According to this type of duct, while the self-propelled trolley is running, the dust generated by the rolling of the wheels and propulsion wheels will be sucked up by the suction device, and the slit portion will also have dust inside the duct. Since the suction force acts on the duct, there is no risk of dust coming out from inside the duct. However, there are various problems even in such a conventional format. In other words, the suction force of the suction device must be applied to the entire length of the duct (traveling path), making the suction device large in size, and furthermore, the suction device with a dust collector must be installed, making the entire system expensive. . In addition, the suction sound becomes noise and is generated over the entire length of the duct.

That is, since the attraction force of the magnet of the self-propelled truck acts on the magnet of the follower truck through the top plate, by running the self-propelled truck, the follower truck can be made to travel integrally. At that time, the side of the self-propelled trolley where dust is likely to be generated is completely sealed by a box-shaped duct, making it possible to eliminate the need for a large suction device with a conventional dust collector, and thus reduce the overall It is possible to reduce the cost, eliminate noise generation, and ensure sufficient cleanliness. In addition, control signals to the self-propelled bogie are given via the signal rail installed on the rail device side, and at this time, signals can be sent and received between both bogies without contact using both coils. Control of the follower carriage can be easily and reliably performed by signals from the rail device.

れる。 The self-propelled cart 4 is driven by applying the rotational force of the motor 15 to the propulsion rotating wheel 1 via the reduction gear 16 and the drive shaft 13.
4, and the propulsion rotary wheel 14 is pressed against and rolled on the second traveling guide surface 24. Since the self-propelled trolley 4 travels within the sealed duct 1, the generated dust does not leak outside. Further, the driven truck 33 travels integrally with the self-propelled truck 4 since the magnets 21 and 36 are attracted to each other. At this time, since the contact portions on the trailing cart 33 side are between the rail 30 and the wheels 32 made of synthetic resin, and between the wheels 32 and wheels 31 made of the same, hardly any dust is generated. The self-propelled cart 4 is controlled by a signal from the signal rail 27 on which the brush 20 slides, and the driven cart 33 is controlled by the signal rail 27.
This is done by applying a signal from the primary coil 22 to the secondary coil 37 through the top plate 2.
