Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for passengers in an entry / exit zone of a cableway facility stop.

[0002]

2. Description of the Related Art Cableway equipment is one in which a carrier is gripped by a gripping machine around a rope wound between pulleys on both ends, and the carriage is operated as the rope moves and is transported. There is a lift using a chair-type carrier and a ropeway using a passenger car-type carrier, and it is generally known that it is often used for transporting skiers in snowy areas or for transporting passengers in mountain tourist areas. In addition, recently, the use of cableway equipment between general transport aircraft for medium or small volume transport is also being aimed at.

[0003] In the conventional cableway equipment, when passengers get in and out of a boarding / alighting area or a boarding / alighting zone, an attendant attends the boarding / alighting operation under safety monitoring to ensure safety. However, in recent years, labor saving and remote monitoring by TV monitoring devices have been implemented in other general transportation systems, new transportation systems, etc., but such a request will be required in the field of cableway equipment in the future. There is a tendency.

[0004]

Needless to say, in carrying out such labor saving and remote monitoring, it is of course necessary to prevent the safety level from lowering than in the past, but in such a case. In the past, almost no consideration was given to equipment for ensuring safety. In response to such a situation, the present invention provides means for ensuring the safety of passengers when the cableway equipment is automated and labor-saving and remote safety monitoring is performed using, for example, a television monitoring device. The purpose is to provide auxiliary means.

[0005]

To solve this problem, the present invention is a safety device provided in a boarding / alighting zone of a cableway stop, and detects the location of a carrier in the boarding / alighting zone and outputs a carrier signal. A carrier detection device, a failure detection sensor that outputs a failure signal when a projection beam is projected near at least the passenger's safety boundary in the boarding / alighting zone, and the projection beam is blocked, and the carrier signal and the failure signal are input. And a discrimination circuit for outputting a security signal, wherein the discrimination circuit is
When the obstacle signal is input, a safety signal is output to perform a safety measure, and the output of the safety signal is canceled at a suitable time when the transport detector detects the location of the transport near the boarding / alighting zone. It is configured as a safety device for the entry / exit zone of the cableway.

[0006]

The safety device for the entry / exit zone of the cableway according to the present invention is installed in the cableway stop. A boarding / alighting zone or a boarding / alighting zone, that is, a boarding zone or a getting-off zone, is arranged along the rail within the stop. Rolling and decelerating. In addition, the carrier that has reached the slow speed reaches in the vicinity of the above-mentioned boarding / alighting zone in this state, and the passenger is treated as a passenger for getting on or off.

In the boarding / alighting zone, a carrying device detecting sensor for detecting that the carrying device has entered the boarding / alighting zone is provided.
When a carrier moves into this boarding / alighting zone, it is detected and a carrier signal is generated and sent to the discrimination circuit of the control device.

On the other hand, at least the safety boundary of the boarding / alighting zone,
That is, a projection beam is projected near the boundary between an area where a person can enter and an area where a person can enter due to the passage of a transporter and is dangerous. A failure detection sensor for outputting is provided. A photoelectric switch, an ultrasonic sensor, or the like is used as a projection beam used for the obstacle detection sensor, and a person who detects the light beam beam or the ultrasonic beam when a person or the like blocks the beam is used.

The carrier signal and the fault signal are input to the discriminating circuit, which discriminates and outputs a security signal.
That is, when the carrier signal of the carrier detection sensor is not output, it is determined that the carrier is absent in the boarding / alighting zone, and when the failure signal of the failure detection sensor is output at this time, people etc. enter the area where the carrier passes. The output signal is sent out after it is determined that the output signal has been received. On the other hand, when the carrier signal from the carrier detection sensor is output, even if the obstacle signal is output by blocking the projection beam for people getting on and off, the safety signal is not output from the discrimination circuit, and passengers can be treated without problems. be able to.

When the safety signal is output, it means that a person or the like interferes with the passage route of the carrier, and the safety signal shuts off the power supply for cableway driving to stop the operation or give an alarm. Safeguards can be taken.

A transfer device 8 is arranged between points D, E, F and near point G.

A dismounting zone 26 is provided near the points C and D along the rail 6, and a boarding zone 21 is provided between the points E and F.

In the present embodiment, the carrier 10 is a passenger car type carrier, and is equipped with a gripping machine 11. In FIG. 1, a carrier 10 grips a rope 3 with a gripping machine 11, travels along a cableway 4 in a direction of an arrow 5a, and enters and arrives in a region 1 of a stop. Next, in the vicinity of the point A, the gripping machine 11 launches the rope 3 and thereafter rolls along the rail 6. And,
The carrier 10 or the gripping machine 11 is slowly decelerated by the deceleration transfer device 7, and the vicinity of the point B passes through the points C, D, E, and F to the point G.
While it reaches the point, it is transferred back at a slow speed by the transfer transfer device 8. In addition, during this period, passengers are treated as passengers near the getting-off zone 26 and as passengers near the passenger zone 21. Next, the carrier 10 or the gripping machine 11
Is accelerated by the accelerating transfer device 9 to a speed equal to the speed of the cord 3, and the gripping machine 11 grips the cord 6 near the point H and starts moving in the direction of the arrow 5b as the cord 6 moves.

In FIG. 1, only two carrying devices 10 are shown and the others are not shown. However, in practice, a plurality of carrying devices 10, 10, ... Are used at predetermined intervals or predetermined time intervals. It will be operated one after another.

FIG. 2 shows details in the vicinity of the riding zone 21 in FIG. Rail 6 is stop area 1
The carriage 10 is installed over the inside and is moved slowly along the rail 6 in the direction of the arrow 5b by the gripping machine 11 which also functions as a traveling machine, from the carriage position 10a through 10b to 10c. ..

The boarding zone 21 shown in a rectangular shape is formed at the same level as the general floor surface in the area 1 of the bus stop or slightly raised, and passengers are guided in the direction of the arrow 25 to get on the boarding zone 21. To the carrier 10, 10 ,.
The fences 22 and 23 are provided to prevent passengers from entering the passage zone 24 of the carrier 10 from the riding zone 21.

Here, the carrier 10 near the boarding zone 21
A carrying device detection sensor 32 (S1) for detecting the approach or approach of the carrying device 10 is provided near the entrance side of the device. In addition, a transporter detection sensor 33 (S2) for detecting a distance from or exiting the transporter 10 riding zone 21 is provided near the exit side of the transport zone near the boarding zone 21. These carrier detection sensors 32 (S1), 33
For (S2), a contact type limit switch type as shown in the figure can be used, and also a non-contact type proximity switch or a photoelectric switch which is shielded by the passage of the carrier 10 to operate. You can

Next, a light projector 36 and a photoelectric switch 37 (PH) which constitute a failure detection sensor 35 are arranged near the safety boundary between the boarding zone 21 and the passage area 24 of the carrier 10, and the light projector 36 is connected to the photoelectric switch. A projection beam 38 of a light beam is projected toward 37 (PH). Although the photoelectric switch is used in this embodiment, a sensor for projecting an ultrasonic beam or the like may be used instead.

In the arrangement relationship of the respective sensors and the like as shown in FIG. 2, these are constructed such that signals are transmitted as shown in FIG.

First, the carrier detection device 31 is composed of carrier detection sensors 32 (S1) and 33 (S2) and a carrier detection circuit 34. The carrier detection sensor 32 (S1),
The detection signal from 33 (S2) is transmitted to the carrier detection circuit 34, and the carrier signal is transmitted from the carrier detection circuit 34 to the determination circuit 39. On the other hand, the failure signal of the photoelectric switch 37 (PH) of the failure detection sensor 35 is also transmitted to the determination circuit 39. The discriminating circuit 39 outputs a security signal based on the above-mentioned input signals.

FIG. 3 shows a specific example of the relationship as shown in FIG. 2 in the case of a contact circuit. The operation of this figure will be described later.

Next, the operation or action of the apparatus of this embodiment will be described with reference to FIGS.

Passing area 2 of the carrier in the passenger zone 21
In the vicinity of the edge with the projector 4, the projector 36 of the obstacle detection sensor 35
From the photoelectric switch 37 (PH) to the projection beam 38 of the luminous flux
Is being projected. It is assumed that the carrier 6 rolls along the rail 3 in the direction of the arrow 5b, is near the position 10a of the carrier, and has not yet reached the boarding zone 21. Therefore, the carrier detection sensors 32 (S1) and 33 (S2) do not detect the passage of the carrier 10.

This state will be described with reference to FIG. 4. First, in the carrier detection circuit 34, since the normally open contact of the carrier detection sensor 32 (S1) is open, the carrier detection sensor 33 (S1).
Even if the normally closed contact of 2) is closed, the relay R1 is not excited, and therefore the normally open contact of the relay R1 for self-holding is also open. The projection beam 38 of the obstacle detection sensor 35 is not blocked and therefore the photoelectric switch 37
(PH) receives light and is operating, and therefore the discrimination circuit 39
The normally open contact of the photoelectric switch 37 (PH) is closed. Therefore, the normally open contact of the relay R1 is open, but the relay R2 is excited by the normally open contact of the photoelectric switch 37 (PH) being closed. Therefore, since the normally open contact or switch 41 of the relay R2 in the security circuit 40 is closed, it is determined that no obstacle has occurred in the riding zone 21 and the operation of the cableway is continuously executed.

In this way, when a person or the like blocks the projection beam 38 of the luminous flux when the carrier 10 is not in the boarding zone 21, the photoelectric switch 37 (PH) does not receive light, and the photoelectric switch 37 in the discrimination circuit 39. The (PH) normally open contact is open. As described above, since the normally open contact of the relay R1 is open, the relay R2 is demagnetized by these, and the normally open contact or switch 41 of the safety circuit 40 is opened. When the security circuit 40 is cut off in this way, it is detected that a person or the like has entered the passage area 24 of the transporter and obstructed the course of the transporter 10, and the operation of the cableway is stopped, or necessary safety arrangements such as alarms and indications are made. It can be carried out.

Next, when the carrying device 10 in FIG. 2 reaches the boarding zone 21 and reaches the vicinity of the carrying device position 10b, the carrying device detection sensor 32 (S1) detects it. At this time, in the carrier detection circuit 34 of FIG. 2, the normally open contact of the carrier detection sensor 32 (S1) is closed, and as described above, the carrier detection sensor 33 (S2) is not operating and is closed. Therefore, the relay R1 is excited, and the normally open contact of the relay R1 is closed and held by itself. Further, the projection beam 38 of the failure detection sensor 35 is still projected, and the normally open contact of the photoelectric switch 37 (PH) in the discrimination circuit 39 is closed by this, but the relay R1 of the relay R1 is also closed. Since the normally open contact is also closed, the relay R2 is thus excited, and thereby the normally open contact or switch 41 of the safety circuit 40 is also closed, and the operation of the cableway is continued.

The carrying device 10 shown in FIG.
During the period from b to 10d, the vehicle travels along the riding zone 21 at a slow speed, during which the doors 12 and 12 are opened and passengers are treated. At this time, the passenger naturally crosses the projection beam 38 and blocks the vehicle to board the vehicle, but during this period, the action of the obstacle detection sensor 35 is released.

That is, in FIG. 4, during this period,
Since the relay R1 of the carrier detection circuit 34 is excited, the normally open contact of the relay R1 in the determination circuit 39 is closed, and the relay R2 is not excited even if the normally open contact of the photoelectric switch 37 (PH) is opened. The safety circuit 40 continues to be energized and the cableway operation is continued.

Further, when the handling of the carrier 10 in FIG. 2 is completed and the doors 12 and 12 are closed and the position near the position 10d of the carrier is reached, the carrier detection sensor 33 (S).
2) detects this. That is, the carrier detection circuit 34 of FIG.
Since the normally closed contact of the carrier detection sensor 33 (S2) is opened, the relay R1 is demagnetized and the self-maintaining normally open contact is opened, and this state is maintained. Further, by this, the normally open contact of the relay R1 in the discrimination circuit 39 is also opened. The carrier 10 is moved from the passenger zone 21 to the arrow 5b.
However, the projector 36 of the obstacle detection sensor 35 continues to project the projection beam 38, and the safety circuit 40 is cut off only when a person or the like blocks the projection beam 38, and safety measures are taken.

That is, in this device, the passenger is guided to the boarding zone 21 in the direction of arrow 25, and the carrier 1 moving at a slow speed.
However, when the carrier 10 is not in the boarding zone 21, a person accidentally passes the carrier passing area 24.
When the vehicle enters, the projection beam 38 is blocked and, as a result, safety measures are taken to ensure the safety of passengers. But,
When the carrier 10 is in the boarding zone 21 and is timely to board, the operation of the obstacle detection sensor 35 is released, and thus the passenger can board the vehicle.

In the present embodiment, the case of the boarding zone 21 has been described, but the boarding zone 26 can be similarly configured. Further, in the present embodiment, the circuit configuration has been described for the case of a contact circuit, but it is clear that the same configuration can be applied to a contactless circuit or the like.

(Embodiment 2) In the case of the above-mentioned embodiment, the carrier detector 31 has carrier detection sensors 32 (S1) and 33 (S2).
2 is used to detect the approaching / distant distance of the carrier 10.

In the second embodiment, the carrier detection device 5
1 shows an example in which only one carrier detection sensor 53 (S3) is used. In FIG. 5, a movable slider-shaped carrying device detecting member 52 is provided near the carrying device positions 10e, 10f, and 10g, and when the carrying device 10 or the gripper 11 passes while coming into contact with the carrying device detecting member 52. The carrier detection sensor 53 is pressed and operates. That is, in this case, the carrier 10
When the vehicle is near the boarding zone 21, the carrier detection sensor 53 continuously detects. Other symbols in FIG. 5 are described with the same symbols as in the first embodiment.

In this case, the carrier detection circuit 54 is as shown in FIG. 6, in which the normally open contact is closed and the relay R1 is excited while the carrier detection sensor 53 (S11) is operating. The following operation is equivalent to that of the above-described embodiment, and even such a configuration operates equally.

[0037]

The safety device for the getting on and off zone of the present invention enables to immediately take safety measures such as operation stop when a person accidentally enters the passage area of the carrier from the getting on or off zone of the cableway. When the carrier is near the boarding zone or the unloading zone and the boarding or unloading is timely, this operation is canceled so that the boarding or unloading can be performed without trouble.

Conventionally, the entry and exit of the cableway has been generally performed under the supervision and guidance of staff members. However, in the future, in the case where the labor-saving and remote monitoring are desired,
This device can be used as an effective means or auxiliary means for ensuring safety. In addition, when getting on and off under the supervision of an attendant, it can be used as an auxiliary means for safety.
