きる。At this time, the normally open power supply circuit switch 4. Since the normally closed control range change switch 10+ paired with is opened, the closed area 2□
Eventually, the striker attached to the transport vehicle ■ comes into contact with a limit switch (not shown), which serves as a vehicle position detection device, installed at the forward end of the blockade area 2.0, turning it on. . Then, a command is issued from the power supply switching control device 7 that has received the ON signal, and the power supply line switch 4□ is closed, while the control range changing switch 10g paired therewith is opened. At the same time, the feeder switch 4. opens, and the control range change switch 101 paired with this opens.
closes. As a result, when the trolley ■ enters the next blocked area, the supply source 31 is used in advance to enter the blocked area 2. The power supply will be cut off and the power supply will be switched from the power supply source 3 to the next blockade area 2□, and the transport vehicle ■ will proceed smoothly while being supplied with power from the power supply line 1 of the blockade area 2□. I can continue.

．． The power supply range in which 0 shares are shared ends. So the next power supply 3t
will be taken over. That is, from the occlusion area 24 to the occlusion area 2.
When the trolley ■ approaches the 8! By switching to 3°, the power source 31 is switched to 3°. During this switching, if the power supplies 31 are short-circuited, the power supplies will be destroyed. To avoid this, the power supply switching control device 7 uses a power supply switching switch 8. It has an interlock function that instructs the next power source switching switch 8□ to be closed after confirming that the switch 8 is completely opened.

If the waveform of the AC power supplied to the trolley drive motor M differs before and after the above-mentioned power supply switching, the motor M will not be driven smoothly, and in the worst case, the phase will be reversed and the motor may stop. . Then, in response to a command from the power supply switching control device 7, the power supply synchronization control device 9 operates to synchronize the output waveform of the power supply R3t with that of the power supply 31, and then the trolley is allowed to enter.

た閉塞域内で停止して衝突は完全に防止できる。The above description has been made of the case where one conveyance vehicle V continues to travel continuously. If you want to bring two carts closer together, you need to prevent the carts from colliding. At that time, when the position detection device detects that the trolley ■1 has entered the immediately adjacent (or adjacent to it across one or two sections of the closed area 21) blockage area, the power supply switching control device 7 The power supply line switch 41 and the corresponding control range change switch 1 in the closed area are

十Ｎ）個であるのに対して、第５図に示す従来のものは
ＮＬ個となる。つまりその差は、Ｎ （Ｌ−１） −２
Ｌであり、給電源の台数と閉塞域の区間数との積ＮＬに
比例してコスト低減の効果が増大することとなる。According to the above embodiment, when the number of power supply sources 31 is N and the number of sections of the closed area 21 is L, the required number of switches is (2L
10N), whereas the conventional one shown in FIG. 5 has NL. In other words, the difference is N (L-1) -2
L, and the effect of cost reduction increases in proportion to the product NL of the number of power supplies and the number of sections in the closed area.

する。In addition, in the above embodiment, each switch was explained as using a normally open and normally closed electromagnetic relay contact type, but it is not limited to this, and it is also possible to use a non-contact switching element type such as Cyrisk. Since the number of switching elements greatly affects the price, the effect of cost reduction is further increased.
