Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides direction selection control of a moving object using power control for automatically branching a moving object from a main line to a side line and merging the moving object from the side line to the main line. Regarding equipment.

Patent application No. 51-100647 proposed by the same applicant
The invention according to No. 53-27973 selects the direction of magnetic flux of two electromagnets mounted on a moving body, which should generate a magnetic attraction force between them and a magnetic belt, by turning on and off the excitation power of the electromagnets. However, although the feature was that the moving body could move straight or branch, there was no mention of on-off control means for selecting the direction of travel.

On the other hand, a series of inventions typified by Japanese Patent Application No. 51-92314 (Japanese Unexamined Patent Publication No. 53-18111) filed by the same applicant have revealed that a mobile object can be operated automatically only by electric power control. A control method has been proposed.

Conventionally, as a traveling direction selection control device for a moving object traveling on a traveling path having a side track installed in parallel with the main line, the traveling direction is switched by a rolling device or a traverser, that is, the branching path or the merging path of the side line with respect to the main line is appropriately selected. Movable structures that are moved by means of This moving direction selection device with a movable structure is prone to problems with the movable mechanism through continuous use, requiring constant maintenance and inspection efforts, and in addition, manual operation is required in the event of trouble, making it difficult for ground personnel to operate the device. Due to the restriction that it must be installed within the area of activity, it is difficult to apply it to continuous transportation systems using unmanned autonomous driving, which has been developed in recent years and will be put into practical use in the near future.

The purpose of this invention is to combine the idea of selecting the traveling direction of a moving object in a continuous transportation system with an extended magnetic belt conveyor unit, which was already proposed by the same applicant, and the idea of automatic operation control of a moving object using electric power control. By combining these, the direction of travel at the branching point or merging point of the side track with respect to the main line can be fixed, and a magnetic belt conveyor unit can be extended to a desired section near the branching point or merging point, and the movement can be driven by electric power control. It selectively drives the magnetic belt conveyor unit at the branching point or merging point depending on the position of the moving body, and automatically selectively excites the electromagnet for selecting the direction of travel mounted on the moving body, and receives an external command signal. The purpose of the present invention is to provide a moving direction selection control device for a moving body using power control that selectively moves straight ahead, branching, and merging depending on the direction of travel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a moving direction selection control device for a moving body according to the present invention will be described in detail below based on the drawings.

FIG. 1 is a plan view showing an example of a running road having a side track installed parallel to a main line to which the present invention is applied. 53-27973).

As shown in FIG. 1, in the traveling route 1, a side line B is branched from the main line A, and the side line B is arranged in parallel over a desired section length, and then merges with the main line A again. This driving route 1
In the vicinity of the branch point P, a magnetic belt conveyor unit B17 for selecting going straight on the main line and a magnetic belt conveyor unit B27 for selecting branching to the side line are installed over a desired length. Further, in the vicinity of the merging point Q of the traveling route 1, a magnetic belt conveyor unit B13 on the main line side and a magnetic belt conveyor unit B23 for merging from the side line are extended over a desired length.

On the other hand, mobile objects MC1 and MC traveling on traveling path 1
2. Each of MC3 is a magnetic belt conveyor unit B17, B1 on the main line side of the branching point or confluence point.
A magnet device 2 that generates a magnetic attraction force between 3 and 3.
and magnetic belt conveyor unit B on the side track.
The tower is equipped with a magnet device 3 that generates magnetic attraction between the magnet devices 2 and 3.
The directions of the magnetic pole end faces of the magnetic poles are made different from each other and selectively excited, that is, controlled on and off.
When entering a branch point P, the moving direction of a moving body can be selected. That is, if the magnet device 2 of the movable body MC1 located on the main line is excited when it enters the branch point P, a magnetic attraction force is generated between it and the magnetic belt conveyor unit B17 of the main line, and the movable body moves along the main line A. Make a straight line. Conversely, if the magnet device 3 of the mobile body MC1 is excited when it enters the branch point P, a magnetic attraction force is generated between it and the magnetic belt conveyor unit B27 on the side track, and the mobile body is branched to the side track B. . In addition, the side line B in FIG. 1 has magnetic belt conveyor units B24, B
25 and B26 are extended, so when a moving body MC3 located on the side track branches into the side track, a magnet device is installed to generate a magnetic attraction force between it and the magnetic belt conveyor unit on the side track. 3 is always kept in an excited state.

In addition, the merging of moving bodies at the merging point Q is carried out between magnetic belt conveyor units B13 and B23, which are driven in response to the approach of moving bodies, for example, between B13 and B23 on the main line.
By forcibly maintaining B23 on the side track in a stopped state when B13 is being driven, that is, by stopping the side track side and preventing moving objects from the main line and the side track when merging.
Without creating a conflict between MC2 and MC3,
This allows for smooth merging.

Go straight on the moving body explained in this FIG. 1,
FIG. 2 shows an embodiment of the traveling direction selection control device of the present invention, which was devised for branching and merging. Each part in the embodiment shown in FIG. 2 is shown to correspond in position to the traveling path shown in FIG.

In the embodiment shown in FIG. 2, the equipment for controlling the operation of moving bodies along the main line is the same as that proposed in Japanese Patent Application No. 52-52685 (Japanese Unexamined Patent Publication No. 52-52685) by the same applicant.
138121) is adopted, and the system has a configuration unique to the present invention in the vicinity of branching points or merging points, and in side track sections.

First, to explain the power supply circuit for power supply control installed along the main line, the three-phase AC power supply line
PF1, PF2, and PF3 are provided, and three contact wires Ti ₁ , Ti ₂ , and Ti ₃ are provided for each predetermined block section and are insulated and divided by a dividing device such as an air gap.
Here, i is i=1 from the front in the moving direction of the moving object,
Integers such as 2, 3, 4, . . . represent each section of the divided contact wire. Among the contact wires Ti ₁ , Ti ₂ , and Ti ₃ , the contact wire Ti ₁ is always kept in a energized state, and the remaining contact wires Ti ₂ and Ti ₃ are energized and controlled according to the progress of the moving object. In addition, each contact wire Ti ₁ , Ti ₂ , Ti ₃
A neutral contact wire T ₄ is also provided.

However, as shown in the figure, in the vicinity of the branching point P and the confluence Q of the running road, there are contact wires T ₃₁ and T ₇₁ that are constantly energized and dummy wires T' ₃₁ and T' ₇₁ that are not energized at all. provided. A single contact wire T ₃₁ is installed near this branching point and confluence point,
The reason for providing T ₇₁ and dummy lines T′ ₃₁ and T′ ₇₁ is as follows.
This will be clarified through the operation explanation later.

In order to constantly energize the contact wire Ti ₁ and to control the energization of the contact wires Ti ₂ and Ti ₃ , a sectional control station SPi is provided in each block section. Separate control center
The basic configuration of SPi is, taking the section control station SP1 in the section of contact wires T ₁₁ , T ₁₂ , and T ₁₃ as an example, a current relay I ₁₁ is inserted in the connection line between the feeder line PF 1 and the contact wire T ₁₁ . and the normally closed contacts of the current relay I ₁₁
Contact wires T ₂₂ and T ₂₃ in the section behind S ₁₁ by one
It is inserted into each connection line between the power supply line PF2 and the power supply line PF2 and _PF3 . Now, if a moving object enters the section of contact wires T ₁₁ , T ₁₂ , and T ₁₃ , the moving object collects current from contact wire T ₁₁ , and a current flows through current relay I ₁₁ . As a result, the contact S ₁₁ is opened, and the contact wires T ₂₂ and T ₂₃ in the one rear section are made unpressurized. Therefore, if another moving object enters the section of the contact wires T ₂₁ , T ₂₂ , T ₂₃ , it will respond to the unpressurized state of the contact wires T ₂₂ , T ₂₃ because current can only be collected from the contact wire T ₂₁ . The vehicle is decelerated or stopped by means such as a power generating brake, and is prevented from entering a section where a preceding moving vehicle exists.

The configuration and power control operation of this sectional control station SP1 are as follows:
The same applies to the remaining divisional control stations SP4, SP5, SP8, excluding SP3, SP6, and SP7.

On the other hand, looking at the drive control circuit for the drive sources M23 to M27 including the electric motors that drive the magnetic belt conveyor units B23 to B27 extended on the side tracks, it is found that
Corresponding to 7, a contact wire Ti ₅ is provided which is insulated and divided by a dividing device such as an air gap. Connection wires are introduced into these contact wires Ti ₅ from the feeder line PF1, and each connection wire receives a branch command signal 1 from the outside.
Self-holding command relays I ₃ to _{I 7} that operate at zero
normally open contacts S ₃ to _{S 7} are inserted. However, the connection lines to the contact wires T ₇₅ and T ₃₅ near the branching point and the merging point are introduced from the feeder line PF1 via the main line side divisional control stations SP7 and SP3. In addition, contact wire T ₇₅
Current relays I ₃₀₁ to _{I 601} are inserted into each of the connection wires to the contact wires T ₃₅ to T ₆₅ , except for the contact wires T 35 to T 65, and their normally closed contacts S ₃₀₁ to _{S 306} connect to the connection wires of the contact wires in the rear section. is inserted into. Furthermore, when each of the command relays I ₃ to _{I 17} is activated by an external command signal, it closes its contacts S ₃ to _{S 7} and at the same time turns on the drive sources M23 to M27 including the electric motors of the magnetic belt conveyor units B23 to B27. Activate it.

Next, there is a section control station SP6, which controls the drive of the magnetic belt conveyor unit B17 for straight movement on the main line, which is installed near the branch point, according to the progress of the moving body.
Let me explain SP7.

First, the divisional control station SP7 inserts the first current relay _I71 into the connection line between the feeder line PF1 and the contact wire _T71 , and connects its normally closed contact _S71 to the contact wire located behind the dummy wire _T'31 . Insert into the connection line between T ₈₂ and T ₈₃ and feeder lines PF2 and PF3. Furthermore, a second current relay I ₇₂ is inserted into the connection line between the feeder line PF1 and the contact wire T ₇₅ near the branch point of the side line, and its normally closed contact S ₇₂ is connected to the first
In series with the normally closed contact S ₇₁ of the current relay I ₇₁ , the feeder
Insert into the connection wire between PF2, PF3 and contact wires T ₈₂ and T ₈₃ . The first current relay I ₇₁ is actuated by the current flowing on the approach of the moving body to the contact wire T ₇₁ ,
The contact S ₇₁ is opened and the contact wires T ₈₂ and T ₈₃ are made non-pressurized, and at the same time, a start command 12 is sent to start the drive source M17 of the magnetic belt conveyor unit B17 for selecting the main line straight travel.

Next, looking at the divisional control station SP6, we see that the power supply line PF1
Only the current relay I ₆₁ is inserted in the connection line between the contact wire T ₆₁ and the contact wire T 61. This current relay I ₆₁ is activated when a moving object enters the contact wire T ₆₁ , and the drive source M 17 of the magnetic belt conveyor unit B 17 for selecting the main line straight forward movement is activated.
A lock command 14 is sent out which prohibits the start-up of the device with priority over the above-mentioned start-up command 12.

Separate control station SP2, SP located near the confluence point
3 has the same configuration as the divisional control stations SP6 and SP7 at the branch point. In other words, the classification control center SP3
is the third connection line between feeder line PF1 and contact wire _T31 .
Insert current relay I ₃₁ and contact wire PF
Insert the fourth current relay I ₃₂ into the connection wire between contact wire T ₃₅ near the confluence of the side wire and the third and fourth current relays.
The normally closed contacts S ₃₁ and S ₃₂ of the current relays I ₃₁ and I ₃₂ are connected to the contact wires T ₄₂ and T ₄₃ in the rear section of the dummy wire T′ ₃₁ and the feeder line.
Insert in series to the connection line with PF1. Activation of the third current relay _I31 sends out a start command 16 to the drive source M13 of the magnetic belt conveyor unit B13 on the main line side. In addition, the classification control center SP2
In this example, a current relay _I21 is inserted into the connection line between the power supply line PF1 and the contact wire _T21 , and its operation activates the drive source M of the magnetic belt conveyor unit B13 extended to the main line.
13, and a lock command 18 which prohibits the activation of the drive source M23 of the merging magnetic belt conveyor unit B23 extended to the side track, with priority over others, such as the command 14 which gives priority to the activation command 12 described above.

The configuration of a mobile body that runs under electric power control in conjunction with the main power circuit and the divisional control center having the above configuration will be explained by taking as an example the mobile body MC1 located on the approach side of a branch point. The mobile body MC1 is equipped with a three-phase AC induction motor as a drive source, and in the illustrated embodiment, the motor is represented by a field coil f connected in a star shape. Collectors P ₁ , P ₂ , P ₃ are connected to each winding of the field coil F, and three-phase AC power is collected from contact wires P ₈₁ , P ₈₂ , P ₈₃ provided along the main line. , causes the mobile body MC1 to travel. From the common connection point of the field coil F, that is, the neutral point, there is a neutral contact wire.
A first circuit section is provided with a connection line connecting T ₄ to current collector P ₄ , and this connection line includes a magnet device 2 having magnetic pole ends facing magnetic belt conveyor units B 17 and B 13 extending to the main line. The field coil F1 (see FIG. 1) is inserted. Further, a second circuit section is provided with a connection line between the collector P ₄ and the collector P ₅ which is in sliding contact with the contact wires T ₃₅ to _{T 75} provided along the side line. is a magnet device 3 having magnetic pole ends facing magnetic belt conveyor units B23 to B27 extending on the side track (see Fig. 1).
A field coil F2 is inserted. Further, a current relay I ₀ is inserted in series with the field coil F2, and this normally closed contact S ₀ is inserted in series with the field coil F1. Therefore, when a current flows to excite the field coil F2, the current relay I ₀ is activated, opening the contact S ₀ and inhibiting the excitation of the field coil F1, thereby forming an automatic priority switching circuit. The remaining mobile MC2,
MC3 also has the same circuit configuration as MC1.

Therefore, the operation of the moving direction selection control device for a moving object according to the present invention having the above-described configuration will be explained separately for main line straight-ahead control and side line branching and merging control.

I Main Line Straight Travel Control The mobile body MC1 located behind the branch point automatically travels straight unless there is a branch command 10 to the side track command relays I ₃ to _{I 7} .

Now, the moving body MC1 located in the section of the contact wires T ₈₁ , T ₈₂ , and T ₈₃ is collecting current from collectors P ₁ , P ₂ , and P ₃ and feeding it to the field coil f of the three-phase AC induction motor. The train is moving toward the branch point at a predetermined speed determined by the power supply voltage. At this time, the current relay I ₈₁ of the divisional control SP 8 is activated by the feed current to the moving body MC 1, and its contacts S ₈₁ and S ₈₂ are opened to make the contact wires T ₉₂ and T ₉₃ one position behind unpressurized. and is blocking the rear.

Subsequently, when the movable body MC1 enters the dummy line T' ₇₁ , the power supply to the field coil f is cut off, and the movable body inertially travels in the section of the dummy line T' ₇₁ . In this embodiment, a dummy line T' ₇₁ is provided, but this is only shown as a preferable example for smooth movement of moving body current collectors P ₁ , P ₂ , and P ₃ at branching or merging points. In that sense, dummy T' ₇₂ and T' ₇₃ for guiding the current collectors P ₂ and P ₃ may be arranged in parallel. In addition, the current relay SP8 of the divisional control station SP8 was restored and the contacts _S82 ,
Close S ₈₃ and pressurize contact wires T ₉₂ and T ₉₃ .

When mobile MC1 further enters, the contact wire
Power is supplied from _T71 to mobile MC1, and the control center SP
7 current relay I ₇₁ is activated. When the current relay I ₇₁ is activated, its contacts S ₇₁ are opened and the contact wire
T ₈₂ and T ₈₃ are not pressurized, and a rear block is applied to the dummy line T′ ₇₁ . At the same time, the activation command 12 is sent to the drive source M17 including the motor of the magnetic belt conveyor unit B17 by activation of the current relay _I71 , and the magnetic belt conveyor unit B17 is driven at a predetermined speed. Of course, in order to start the magnetic belt conveyor unit B17,
The condition is that there is no other moving body in the section in front of the contact wire T ₇₁ and that the lock command 14 is released with the current relay I ₆₁ of the sectional control station SP 6 being deactivated.

On the other hand, looking at the circuit operation of mobile body MC1 when mobile body MC1 enters contact wire _T71 , the field coil F of the induction motor only receives power from collector _P1 , and the interphase balance is disrupted. , cannot generate a rotating magnetic field, and an unbalanced current flows from its neutral point toward the current collector _P4 . The field coil F1 is excited by this unbalanced current, and as a result, a magnetic attraction force is generated between the magnetic belt conveyor unit B17 and the magnet device 2 (see Fig. 1) having a magnetic pole end facing the magnetic belt conveyor unit B17. The body MC1 follows the magnetic belt conveyor unit B17 and selectively moves along the main line from the branch point.

In addition, when the current relay I ₇₁ of the divisional control station SP7 is activated, its contact S ₇₁ is opened _{, which blocks the section of the contact wires T 82 and} T ₈₃ one place behind the dummy wire T' 71, and Since the power supply to the contact wire _T75 is also cut off, as long as the moving object is being followed by the magnetic belt conveyor unit B17,
Even if a branch command 10 is given to the command relay I ₇ of the side line and the contact S is closed, the contact wire T ₇₅ is maintained without pressure.

Next, when the moving body MC1 exits the following traveling section by the magnetic belt conveyor unit B17,
Current relay I ₇₁ is restored and closes its contacts S ₇₁ ,
Solve the backward block for dummy line T′ ₇₁ . At the same time, the field coil F of the induction motor of the movable body MC1 is supplied with power by current collection from the contact wires T ₆₁ , T ₆₂ , and T ₆₃ , and the movable body MC1 begins to run under its own power. In addition, with the restoration of current relay I ₇₁ at divisional control station SP7, drive source M1
The start command 12 to the magnetic belt conveyor unit B17 is cut off, and the magnetic belt conveyor unit B17 stops.
The lock command 14 is sent to the electric motor M17 by actuation of the current relay _I61 of SP6. Therefore, other following moving objects cross the dummy wire T′ ₇₁ and touch the contact wire.
Even if the current relay _I71 is activated and the start command 12 is sent out when entering the section _T71 , the magnetic belt conveyor unit B17 is not started and the electric motor M1
A moving object that enters the stopped magnetic belt conveyor unit B17 with the belt 7 locked is subjected to a magnetic braking action by the magnetic attraction force between the magnet device 2 (see Figure 1) and the magnetic belt, and is decelerated to a stop. reach.

Furthermore, mobile body MC1 connects contact wires T ₆₁ , T ₆₂ , T ₆₃
When exiting the section, the current relay _I61 of the divisional control station SP6 is restored, the lock command 14 is released,
Magnetic belt conveyor unit B17 for straight selection
is placed in a standby state for the subsequent entry of other moving objects.

Next, straight forward running of a moving object at a confluence point will be explained using the illustrated moving object MC2 as an example.

The mobile body MC2 located in the section of the contact wires T ₄₁ , T ₄₂ , and T ₄₃ must firstly be aware that there is no other mobile body preceding it in the section of the contact wire T ₃₁ ahead of it, and secondly that the side track It receives three-phase AC power and travels at a predetermined speed under the two conditions that there are no other moving objects attempting to merge into the section of trolley wire T ₃₅ that is the merging section. When the movable body MC2 enters the dummy wire T' ₃₁ , the three-phase AC power supply is cut off, and it enters the section of the contact wire T ₃₁ by inertial running.

When the moving body MC2 enters the contact wire T ₃₁ , the current relay I ₃₁ of the segment control station SP3 is activated and the contact S ₃₁ is activated.
is opened, and the contact wires T ₄₂ and T ₄₃ are left unpressurized to block the rear, and the contact wire T ₃₅ in the merging section of the side track is unpressurized. At the same time, the current relay _I31 is activated, and a start command 16 is sent to the drive source M13 of the magnetic belt conveyor unit B13. The drive source M13 rotates the magnetic belt conveyor unit B13 at a predetermined speed on the condition that the current relay _I21 of the divisional control station SP2 is not activated and the lock command 18 is released. On the other hand, the contact wire
Looking at mobile body MC2 when it enters T ₃₁ , since it only receives power from the contact wire T ₃₁ , the balance of the field coil F of the induction motor is lost, and an unbalanced current flows toward the contact wire T ₄ . flows. The field coil F1 is excited by this unbalanced current, and a magnetic attraction force is generated between the magnetic belt conveyor unit B13 and the magnet device 2 (see FIG. 1) having a pole end facing the magnetic belt conveyor unit B13. It is moved following the magnetic belt conveyor unit B13.

Moving body MC2 is magnetic belt conveyor unit B
13 and enters the section of contact wires T ₂₁ , T ₂₂ , and T ₂₃ , the current relay I ₃₁ of the sectional control station SP 3 is restored, its contact S ₃₁ is closed, and the rear block to the dummy wire T' ₃₁ is released. . At the same time, the entry of the mobile body MC2 activates the current relay _I21 of the divisional control station SP2 and sends out the lock command 18. Therefore, as long as the movable body MC2 exists in the section of the contact wires T ₂₁ , T ₂₂ , T ₂₃ , the lock command 18 causes the drive sources M 13 to
M23 is locked preferentially, and the main line magnetic belt conveyor unit B13 and the side line merging magnetic belt conveyor unit B23 are not rotated.

Furthermore, the mobile body MC2 connects the contact wires T ₁₁ , T ₁₂ ,
When entering the section _T13 , the current relay _I21 of the divisional control station SP2 is restored, releases the lock command, and remains in a standby state to control the movement of the moving body at the junction. In this way, a moving object traveling on the main line must either make one rear section where the moving object is present non-pressurized by electrical power control, or lock the drive of the extended magnetic belt conveyor unit. Then, the moving body is automatically controlled to run continuously at a desired interval.

Side track branching and merging control Direction selection control for branching moving objects running on the main line to the side track and for moving moving objects running on the side track to follow the main line is performed by issuing a branch command 10 from outside by an appropriate means based on desired operating conditions. This is done by giving

Now, the movable body MC1 is connected to the illustrated contact wires T ₈₁ , T ₈₂ ,
Assume that branch command 10 is given when the vehicle is located in section _T83 . Due to branch command 10, the feeder line PF
Command relays I ₃ to _{I 7} provided corresponding to the connection lines between contact wires T ₃₅ to _{T 75} of the side wires are activated to close their contacts S ₃ to _{S 7} . The branch selection condition is established by closing these contacts S ₃ to S ₇ . In addition, when the command relays _I3 to _I7 are activated, the drive sources M23 to M27 of the magnetic belt conveyor units B23 to B27 installed on the side track are activated, and each magnetic belt conveyor is operated at a predetermined speed. The unit is rotated.

When the mobile body MC1 enters the dummy line T ₇₁ ′, the three-phase AC power supply is cut off and the mobile body MC1 runs inertially. What should be noted here is that in the preferred embodiment in this figure, the entry side end of the contact wire _T75 on the branch side is connected to a dummy wire.
It has been extended to section T' ₇₁ . Therefore, while the mobile body MC1 is inertial traveling on the dummy wire, that is, at an appropriate time before proceeding to the side track side conveyor unit B27 section, its current collector _P5 comes into sliding contact with the contact wire _T75 , and the feeder line PF1→contact S ₇₁ → Current relay I ₇₂ → Contact S ₇ → Contact S601 → Contact wire T ₇₅ → Current collector P ₅ →
A circuit of current relay I ₀ → field coil F2 - current collector P ₄ - neutral contact wire T ₄ is formed, and feeder line PF1
A current flows through the field coil F of the moving body MC1.
2 is excited. Therefore, by extending the length appropriately, the excitation delay time due to the inductance of the field coil can be compensated for. This includes the other conveyor units B17 and B13 near the branching and merging points, the corresponding trolley wires T ₇₁ and T ₃₁ , and even the conveyor units B26, B25, and B2 on the side track.
4. The same can be said of the contact wires T ₆₅ , T ₅₅ , and T ₄₅ corresponding to these, and their positions may be relatively shifted to the rear. Further, when the current relay I ₀ of the moving body MC1 is activated, its contact S ₀ is opened, and the excitation of the field coil F1 is prohibited. When the field coil F2 of the moving body MC1 is excited, the magnet device 3 (see FIG. 1), which has a magnetic pole end facing the side line branching magnetic belt conveyor unit B27, becomes excited. When the mobile object MC1 exits the dummy line T ₇₁ ′,
A magnetic attraction force is generated between the magnet device 3 of the movable body MC1 and the magnetic belt conveyor unit B27, and the movable body MC1 is guided by the magnetic belt conveyor unit B27 and branched from the main line to the side line. Furthermore, when the current collector P ₅ of the moving body MC1 comes into sliding contact with the contact wire T ₇₅ , the current relay I ₇₂ of the sectional control station SP7 is activated, so its contact S ₇₂ is opened and the contact wires T ₈₂ and T ₈₃
By applying no pressure to the dummy line T _{71 ′, a rear block is applied to the dummy line T 71} ′.

When the movable body MC1, which has moved following the magnetic belt conveyor unit B75 and branched to the side track, leaves the magnetic belt conveyor unit B27 and enters the section of the next magnetic belt conveyor unit B26, it collects current from the contact wire _T65 . Then, the excitation of the field coil F2 is maintained. Collecting current from this contact wire T ₆₅ , the current relay I 6 inserted into the connecting wire
01 is activated, opening the permanent contact S601 inserted into the connection line of the trolley wire _T75 one position behind. That is, a rear block is applied to the contact wire T ₆₅ . Therefore, the contact wire T ₇₅ is made unpressurized, and at the same time, the current relay I ₇₂ of the sectional control station SP7 is also restored, its contact S ₇₁ is closed, and the rear block to the dummy wire T' ₇₁ ' is released. In this case, the self-hold of the command relay _I7 may be released in response to the operation of the current relay I601, and the magnetic belt conveyor unit B27 may be stopped. Similarly, the movable body that has entered the side track is followed by the magnetic attraction force between the movable body and the extended magnetic belt conveyor unit.

Next, to explain the merging control, as shown in the figure, the movable body MC3 is now being moved following the section of the trolley wire _T45 by the magnetic belt conveyor unit B24. When the movable body MC3 leaves the magnetic belt conveyor unit B24, the moving body MC3 enters a follow-up movement by the merging magnetic belt conveyor unit B23. This follow-up movement by the magnetic belt conveyor unit B23 is possible if there is no other moving body moving straight in the section of the main line's trolley wire _T31 , if the contact _S31 is closed due to the non-operation of the current relay _I31 , and if the main line contact wire
There are no other moving objects in the sections T ₂₁ , T ₂₂ , and T ₂₃ ,
This is done on the condition that the lock command 18 from the current relay _I21 is released. At the same time, if the moving body is being transferred by the magnetic belt conveyor unit B23, the current in the section control station SP3 is generated through the excitation of the moving body field coil F2 due to the sliding contact between the current collector _P5 of the moving body MC3 and the contact wire _T35 . Relay I ₃₂ is activated, leaving contact wires T ₄₂ and T ₄₃ of the main line unpressurized, and applying a rear block to the section of dummy wire T ₃₁ ′. Therefore, magnetic belt conveyor unit B23
The mobile body MC3, which is being moved following the main line, smoothly merges onto the main line without colliding with or being obstructed by other moving bodies that are proceeding straight on the main line toward the merging point.

In addition, in the main electric circuit along the main line in the embodiment shown in Fig. 2, the contact wires Ti ₂ and Ti ₃ in the section behind the moving object are not pressurized to decelerate the following moving object or to slow down the following moving object as necessary. In that case, block control was adopted to bring the vehicle to a stop, but if the preceding moving object suddenly stops due to a malfunction or the like, the following moving object may not be sufficiently decelerated and a rear-end collision may occur. As a solution to this problem, the length of each section should be made sufficiently long to increase the distance between the following moving object and the following moving object to ensure deceleration and stop, or the method proposed by the same applicant, 52−
As in No. 70025 (Japanese Patent Publication No. 60-30167), it is necessary to make one rear section where the moving object is present non-pressurized, and also to depressurize and energize the one rear section.

Furthermore, by using the magnetic attraction force generated by the magnetic belt conveyor unit and the magnet device mounted on the moving body, for example, the magnetic belt conveyor unit B17 extended near the branch point can be moved to the rear of the dummy line _T'71 . If the contact wires T ₈₁ , T ₈₂ , and T ₈₃ are extended over the sections, and the preceding moving object stops in the section of the contact wire T ₇₁ , the following moving object has the contact wire T ₈₁ .
An unbalanced current is generated due to current collection, and the field coil F1
is excited, and the magnetic belt conveyor unit extending along the main line can be reliably stopped by the magnetic braking effect due to the magnetic attraction force.

In addition, in response to the electric current applied to the moving object that has entered the contact wire T ₇₁ , the magnetic belt conveyor unit that extends to the sections of the contact wires T ₈₁ , T ₈₂ , and T ₈₃ is moved in the opposite direction to the moving object traveling direction. When the magnetic belt is rotated in the direction, in addition to the magnetic braking effect due to interlinkage and adsorption between the magnetic belt and the magnetic flux of the moving body field, an eddy current braking effect is generated due to the eddy current generated on the motor side.
The moving body can be automatically stopped more reliably.

In order to stop the moving body, the magnetic belt conveyor unit is rotated in the opposite direction to the direction of movement of the moving body. In the embodiment shown in FIG. It can be applied to drive control of B17 and B13. That is, the lock commands 14 and 18 sent to the drive sources M17 and M13 by the operation of the current relays I ₆₁ and I ₃₁ are used as reverse commands, and the reverse commands cause the magnetic belt conveyor units B17 and B13 to move in the opposite direction in the moving body traveling direction. By rotating the magnetic belt, the relative speed difference between the magnetic belt and the magnetic flux of the moving body field can be increased, and a sufficient eddy current braking effect can be obtained, so that the moving body can be stopped in a short period of time. The fact that this eddy current brake can decelerate and stop a moving object in a short period of time shortens the traveling distance of the moving object and increases the speed of the moving object, making it necessary for transportation. It brings about an increase in capacity.

In addition, although the embodiment shown in Fig. 2 has a desired number of magnetic belt conveyor units extending over the entire length of the siding section, in order to branch or merge between the main line and the siding line, it is necessary to It is sufficient that the belt conveyor unit B27 and the magnetic belt conveyor unit B13 at the junction point are extended, and the remaining side track sections may have the same power circuit configuration as the main line.

The embodiment shown in FIG. 2, in which the magnetic belt conveyor unit is installed over the entire length of the side track, is suitable when acceleration/deceleration control is required for moving objects traveling on the side track. For example, there is a case where boarding and alighting facilities are installed in a desired section of a siding, deceleration control is required when entering the boarding and alighting facility, and acceleration control is required after passing the boarding and alighting facility.

As explained above, the traveling direction selection control device for a moving object according to the present invention automatically controls the traveling of a moving object by electric power control without using a movable branching and merging device that switches the traveling route at a branch point or a merging point. By the combination of the main electric circuit and the magnetic belt conveyor unit, the moving direction of the moving object is automatically selected as the moving object moves toward the main line or the side line at the branch point, depending on the presence or absence of an external branch command signal. In addition, even at a merging point, smooth merging control is automatically performed in which mobile objects that have entered the merging section of the main line or side line in advance are given priority to merge.
