の閉塞内には１台の台車しか入れない制御を行う。A plurality of these transport vehicles are prepared on the same track, and the drive motors of the trolleys are each supplied with drive power from power sources such as multiple inverters installed on the ground via power lines, and The commands control the running status of the bogie, such as starting, running, and stopping. In order to prevent bogie collisions during the travel control described above, the power supply line is divided into a number of insulated sections (called blockages) at regular intervals, and control is carried out so that only one bogie can enter one blockage. conduct.

開閉器４１を配設している。In addition, it is necessary to stop the vehicle at a fixed position at a loading/unloading station within the blockage, which requires speed control during travel. In such a case, the simplest configuration is one in which an off-shore drive device (a direct-motion power source on the ground) is provided for each blockage, as shown in FIG. In other words, the transport vehicle■
The motor M is installed so that the blade can run on a rail (not shown).
A power supply line 1 that supplies driving power to the motor M includes a large number of closed M lines arranged along the rail and insulated from each other.
2 i (i=1.2, 3, . . . ), and a driving device (power source) 31 is provided so as to correspond to each blockage 21 at a ratio of 1:1. Further, a power supply line switch 41 is provided for each power supply line 51 that connects the corresponding blockage 21 and the power source 31.

Controls power supply to 1. In other words, the truck V is blocked 2. When the switch 41 is closed, the power supply line 5 is closed.
．． Power #31 is supplied to the blockage 2 via the trolley shoe S, and power is supplied to the motor M via the trolley shoe S, so that the trolley V runs. Then, just before the cart ■ moves to the blockage 2□, the switch 4□ closes and the switch 41 opens. This makes the power source 3.
motor M is switched to block 2. Power will be supplied to the Similarly, as the trolley V advances, the blockages 21 that are supplied with electricity are sequentially set to i=x, 2.3.・・・・・・
Power supply control is performed by moving the During this time, collisions are prevented even though more than one truck enters the same blockage 21.
しかし、上記第３図に示す方法は動力源３１が各閉寒２
１毎に設けられるから設備費が嵩むという問題がある。However, in the method shown in FIG. 3 above, the power source 31 is
There is a problem that the equipment cost increases because it is provided for each unit.
そこで、第４図に示すような母線方式の走行制御方式の
ものが提案されている。Therefore, a bus bar system running control system as shown in FIG. 4 has been proposed.

台車を接近させることができる。In this case, it is possible to freely switch and control the power source 31 for any blockage 21 by commands from the power supply switching control device 7, and therefore, the power source 31 can be freely switched and controlled with respect to any blockage 21. Even with R3i, it is possible to bring the cart close to an adjacent blockage.

4.Since the connection is made through old..., the number of required switches is the number of power sources m x the number of blockages 2, and as the number of power sources 31 and blockages 21 increases, the number of power supply line switches increases. There are problems in terms of economics and maintenance of equipment.

Since another bogie v2 is stopped at , it is necessary to prevent a collision. At that time, the trolley vI is immediately adjacent to the blockage 2.
When the position detection device detects that the user has entered the room, the switching computer 7 issues a command to close the blockage 2. Switch 4C+ in
The connection is opened and the truck V is stopped. Therefore, the trolley V

When the vehicle is traveling at high speed within the blockage 2I, only the switch 4A is closed and all other switches are open. Trolley v
1 moves in the direction of the arrow, and when it approaches blockage 2□, the truck vl
The striker contacts the limit switch and turns on. Due to this ON operation, a command is issued by the signal input to the switching computer 7, and the switch 4Bz of the blockage 2□ is closed, and the switch 4A is opened, and the bogie v1 that has entered the blockage 2□ is driven via the bus line M2. It is powered by the device 12 and moves at a medium speed.

Power is supplied from the drive device 13 via 3, and the motor moves at a low speed,
Truck striker and blockage 2. When the upper fixed position limit switch is engaged, the switch 4C3 is opened, and the truck V stops at the fixed position P point. At this time, since the bogie moves while being decelerated in three stages according to the running pattern shown in Figure 2(b), the inertia of the move becomes extremely small in the immediate vicinity of the fixed position P, and almost at the same time as the switch 4G opens. Stop.

Although there are three low speed ways, the present invention is not limited to three ways, and may be two or four ways. However, the capacity of each drive device must be sufficient to operate all the bogies at once.

も小さく安価に構成できる等、種々の効果を得られる。As explained above, according to the present invention, it is possible to control the running of any bogie in a running pattern in which a plurality of speeds are selected at any blockage. The number of circuits and the number of circuit contacts can be significantly reduced, improving economic efficiency. Also, if the capacity of the drive device is within the range, the number of trolleys can be changed,
This makes it easier to change the capacity of the trolleys, improving the flexibility of the system, and since switching control and speed control can be performed simultaneously, the switching computer capacity is small and can be configured at low cost, among other benefits. It will be done.
