Description

Description: TECHNICAL FIELD The present invention relates to an automatic circulating cableway transporter transport method and device, and more particularly, to a transporter arriving at one stop and another transporter preceding it. The present invention relates to a carrier transport method and a device therefor, which are adjusted to a constant interval and are sent to the other stop. This is the field of the automatic circulation type cableway, in which a carrier equipped with an automatic detachable gripping machine grips a rope and moves, and at the stop, it is forwarded and turned in the released state. Used.

[Prior Art] In an automatic circulation type cableway, for example, a driving pulley that is rotated by a drive source (for example, an electric motor) provided at a foothill stop,
A rope is circulated endlessly between a driven pulley installed at a stop on the mountaintop and circulated. The rope is supported by a rope attached to a plurality of columns standing upright between the two stops, and moves at a predetermined speed. In that line,
A large number of carriers are suspended at almost constant intervals via a gripping machine.

The carrier holds the line between the two stops, moves to the other stop as the line moves, and releases the line when it arrives at the stop. A deceleration section in which rails are installed is provided at the stop, and the discharged carrier is slowed down by a plurality of deceleration rollers and sent to the chain conveyor section. In the chain conveyor section, the speed of the carrier is lower than the speed of the rope, so that the passenger can get off the carrier and board.

By the way, the free roller section is located on the upstream side of the carrier conveyor chain conveyor that turns the direction of the carrier 180 degrees inside the stop, and is installed only on one side of the stop. The drive rotation speed of many free rollers provided there is set lower than that of the chain conveyor, but when the carrier passing through the free roller section is pushed by the pawls of the carrier conveyor chain conveyor and becomes in a state of increased speed. , Some free rollers in contact with the carrier are allowed to rotate faster than their drive speed.

A plurality of pawls for receiving the carrier are attached to the carrier conveyer chain conveyor at regular intervals, and the carrier that is in a standby state while moving at low speed in the free roller section is held at a constant speed and at constant intervals. , Send to the other stop to the position where it is sent. The downstream side of the carrier conveyer chain conveyor is connected to an acceleration section where rails are installed, and the number of acceleration rollers accelerates the carrier. When the carrier reaches the moving speed of the rope, the gripping machine grips the rope and is sent to the other stop.

In this way, the carrier transporting chain conveyor transports each carrier to the accelerating section at the intervals of the claws, so that the distance between the carrier and the preceding carrier is kept constant. That is, care is taken so that the carrier and other carriers do not come very close to each other and there is no hindrance to getting off or boarding at the stop that has arrived.

The reason why the distance between the carriers is positively set at one stop is that the carriers are automatically detachable.
That is, the carrier is sent out at a constant interval by the carrier conveyer chain conveyor so that the carrier grips the cord at a predetermined position in the acceleration section, but some deviation in the gripping operation is avoided. I can't. Therefore,
The carrier will move toward the other stop with the gap.

The other stop is also provided with a carrier conveyor chain conveyor, but it is not an expensive type with a carrier interval adjustment function like the one conveyor carrier conveyor chain described above, but usually a carrier. Only a large number of claws are provided at intervals much shorter than the intervals. Therefore, if there is a gap in the distance between the carriers, when the carrier is transferred from the deceleration section at the other stop to the carrier conveyor chain conveyor, the carrier should be kept in the same position or the carrier should be supported 180 A diversion occurs. Of course, a gap may occur due to getting off or boarding. Since the carrier with the deviation thus generated returns to one of the stops, the deviation is removed by the carrier conveyor chain conveyor having a function of holding a constant interval.

[Problems to be Solved by the Invention]

By the way, in a conventional automatic circulation type cableway, a driving pulley for moving the rope is driven by an electric motor or the like, but as described in, for example, Japanese Patent Publication No. 64-10382, its power is mechanical. Not only the decelerating roller in the decelerating section, the accelerating roller in the accelerating section, the free roller in the free roller section, but also the chain conveyor for transporting the transporter are supplied through the transmission mechanism.

The use of such a transmission mechanism has the advantages that only one electric motor needs to be adopted and that the mechanical transmission makes it easy to interlock each device. In addition, in the above example, even though such a transmission mechanism is provided,
The above-mentioned function of adjusting the interval between the carrier units by the carrier-conveying chain conveyor can be exerted.

However, in order to configure the power transmission mechanism installed in the stop, various long and short transmission shafts are arranged in the frame of the stop, and many gears are interposed on these transmission shafts. In addition, there are various transmission mechanical elements, and their structural arrangements are various, which makes the entire transmission device extremely complicated. In addition, maintenance and inspection thereof require a great deal of labor, and there is a problem that the construction cost of the automatic circulation type cableway is significantly increased.

In particular, the power transmission mechanism that supplies power to the carrier conveyor chain conveyor becomes even more complicated. Therefore, even if power is supplied to the acceleration roller etc. from the main drive source for driving the prime mover, if a separate electric motor is installed to drive the chain conveyor for transporting the carrier, the power transmission mechanism will be greatly simplified. It will be realized. As such an example, Japanese Laid-Open Patent Publication No. 2-169365 discloses an interval control device capable of performing a shift control of an electric motor that drives a carrier transport device so that the interval between the carrier at a stop can be fixed. Has been done.

In this control device, a large number of transport wheels are adopted in the transport device transporting device, and the rotational speed of the wheels is adjusted for each transport device transported. However, it cannot be denied that the control of the wheels becomes complicated, and the above-mentioned carrier transporting chain conveyor provided with the pawls does not have wheels, and the control method cannot be immediately applied. On the other hand, as described above, if the drive system of the prime mover and the drive system of the carrier conveyer chain conveyor are kept independent, in the operation of the carrier conveyer chain conveyor, there is a gap between the conveyer moved by the rope. Occurs, and there is a problem that its adjustment is not easy.

That is, the rope is operated so as to move at a predetermined speed, but the speed may change due to the operation of the carrier. In that case, the speed of the motor for the carrier conveyor chain conveyor, which is independent of the main drive source for driving the prime mover, is also changed, but it is technically difficult to obtain reliable synchronization. There are many. Therefore, when an electric motor for the carrier transporting chain conveyor is installed separately from the main drive source, it is possible to easily take a control form that realizes an operation that does not hinder the operation of the carrier. desired.

The present invention has been made in view of the above points, and its purpose is to:
In addition to simplifying the power transmission mechanism in the automatic circulation type ropeway to suppress the rise in construction costs and reducing maintenance and inspection work, the electric motor of the chain conveyor for transporting the carrier is provided separately from the main drive source for the prime mover, It is possible to eliminate the complexity of control on the operation of the transporter due to the independent operation of both drive sources, and when the transporter makes one reciprocation, surely restore the predetermined interval with the preceding transporter to ensure high safety. It is an object of the present invention to provide an automatic circulating cableway carrier transport method and device for realizing the operation.

[Means for Solving the Problems]

According to the present invention, when a carrying device hung on a rope arrives at one of the stops, the carrying device is released and decelerated in a deceleration section, and when the free roller section provided at the end of the deceleration section is reached, Is pushed by the pawls provided at regular intervals on the carrier transporting chain conveyor and turned, and then the carrier is sent to the acceleration section at the constant intervals, after which the carrier grips and moves to the other stop. Applicable to self-circulating cableway.

The feature is that, with reference to FIG. 1, the electric motor 15 for driving the carrier conveying chain conveyor 8 is
It is provided independently of the main drive source 6 that drives the prime mover 2 for moving the rope. When one of the pawls 9 of the carrier conveyor chain conveyor 8 is at the first predetermined position N ₁ up to the free roller section L ₂ for receiving the carrier 7, the predetermined approach position N in the deceleration section L ₁ is reached. _{If the} carrier 7 does not pass through ₂ , the electric motor driving the chain conveyor 8
That is to slow down 15.

In the invention of the apparatus, the free roller means 16 for putting the carrier 7 decelerated in the deceleration section L ₁ in the stand-by state while moving at low speed in the free roller section L ₂ and the conveyor conveyor chain conveyor 8 are provided. For driving, a main drive source 8 that drives the prime mover 2 for moving the rope is provided with an electric motor 15 that is provided independently. Further, a claw body detection first switch means 10 for detecting that one of the claw bodies 9 of the carrier conveyer chain conveyor 8 has reached a first predetermined position N ₁ up to a free roller section L ₂ for receiving the carrier 7. A transporter detection first switch means 12 for detecting that the transporter 7 has passed the predetermined approach position N ₂ in the deceleration section L ₁ is installed. When the claw body detection signal from the claw body detection first switch means 10 and the carrier body detection signal from the carrier machine detection first switch means 12 are received, the rotation speed of the electric motor 15 is maintained and the carrier machine transport chain conveyor 8 While holding the speed, when the claw body detection signal from the claw body detection first switch means 10 is received but the carrier machine detection signal is not received from the carrier machine detection first switch means 12, the electric motor 15 is decelerated. That is, the deceleration command control means 14 for issuing a command is provided.

By the way, one of the pawls 9 of the carrier transporting chain conveyor 8 detects the passage of a second predetermined position N ₃ defined between the first predetermined position N ₁ and the free roller section L _2. If the detection second switch means 11 is provided, the deceleration command control means 14 causes the claw from the claw body detection second switch means 11 when the motor 15 is decelerated to move the carrier transport chain conveyor 8 at a low speed. When the body detection signal is received, a speed recovery command unit 19 for returning the carrier conveyor chain conveyor 8 to the original speed can be provided thereafter.

In addition, if the carrier detection second switch means 13 for detecting the carrier 7 received by the claw body 9 of the carrier conveying chain conveyor 8 at the downstream position N ₄ after passing the free roller section L ₂ , is provided, The deceleration command control means 14 operates the motor 15 until the carrier detection signal from the carrier detection second switch means 13 is received after the speed recovery command portion 19 returns the carrier conveyor chain conveyor 8 to the original speed. While the deceleration waiting control that enables deceleration control is prohibited, the electric motor 15 is received after receiving the carrier detection signal from the carrier detection second switch means 13.
Deceleration wait control restart command section 20 that enables deceleration wait control of
Can be provided.

[Action]

A motor 15 independent of the main drive source 6 that drives the drive pulley 2.
In the carrier conveyer chain conveyor 8 driven by
When one of the claw bodies 9A is in the first predetermined position N ₁ up to the free roller section L ₂ for receiving the carrier 7A, the rope 5 is released to start the free roller from the deceleration section L _1. time before entering the section L _2, i.e., a predetermined approach position N ₂ set in the deceleration section L _1, if the carriage 7A plan above the pawl body 9A receives passes, carriage forwards for chain conveyor 8 Electric motor
Run with 15 at the same speed as before, and let its claw 9A receive the carrier 7A.

However, when the pawl body 9A has reached the first predetermined position N ₁ and the carrier 7A to be pushed by the pawl body 9A has not yet passed the predetermined approach position N ₂ , the carrier conveyer chain conveyor 8 is driven. The speed of the electric motor 15 is changed so that the carrier conveyor chain conveyor 8 is decelerated. By doing this, the carrier 7A
Even if the arrival of the carrier is delayed,
Since the delayed also the moving speed of the predetermined pawl member 9A in not that the pawl member 9A passes prior to carriage 7A a free roller section L _2, enters the free roller section L ₂ delayed and wait A predetermined claw body 9A can receive the carrier 7A in the state.

In the device provided with the deceleration command control means 14, the claw body detection first switch means 10 reaches the free roller section L ₂ where one of the claw bodies 9A of the carrier conveyer chain conveyor 8 receives the carrier 7A. the first predetermined position when detecting that came to N ₁ of the carriage detects the first switch means 12, carriage 7A at a predetermined approach position N ₂ in the deceleration section L ₁ detects that it has passed, carriage forwards for chain conveyor The rotation speed of the electric motor 15 of No. 8 is maintained, and the moving speed of the pawl body 9A is maintained. In this case, since the carrier 7A is moving without delay, the pawl 9A that has kept the speed receives the carrier 7A as scheduled.

On the other hand, when the claw body detection first switch means 10 detects that the claw body 9A has reached the first predetermined position N ₁ , the carrier detection first switch means 12 must detect the carrier 7A at the predetermined approach position N _2. ,
A command to decelerate the electric motor 15 is issued and the pawl 9A moves to the carrier 7A.
It does not enter the free roller section L ₂ prior to, and the pawl 9A can receive the carrier 7A as planned.

Incidentally, one 9A of the pawl member 9 of carriage forward for chain conveyor 8 detects that it has passed the second predetermined position N ₃ defined between the first predetermined position N ₁ and the free roller section L ₂ If the claw body detection second switch means 11 is provided and the deceleration command control means 14 is provided with the speed recovery command section 19, the deceleration command control means 14 has already decelerated the electric motor 15 and the carrier conveyor chain conveyor 8 When the claw body detection signal is received from the claw body detection second switch means 11 while the is moving at a low speed, the chain conveyor 8 for transporting the carrier is returned to the original speed thereafter. Even if the pawl 9A is delayed based on the delay of the carrier 7, it does not delay the pawl 9A from entering the free roller section L ₂ too much, and the pushing start of the carrier 7A is accelerated to cause a slow forwarding state. Can be avoided.

If the deceleration command control means 14 is provided with the deceleration waiting control restart command unit 20 in addition to the speed recovery command unit 19, the speed recovery command unit 19 restores the carrier conveyor chain conveyor 8 to the original speed. After that, until the carrier detection second switch means 13 detects the carrier 7A at the downstream position N ₄ after passing the free roller section L ₂ , the deceleration waiting control that enables the deceleration control of the electric motor 15 is prohibited. be able to. by this,
In the meantime, even if there is a delay in the succeeding carrier 7 and the speed of the carrier conveying chain conveyor 8 is reduced, the preceding carrier 7A can be quickly expelled from the free roller section L ₂ , and its claw 9A It is possible to prevent the transported carrier 7A from being slowly transported due to the delay of the succeeding carrier 7. On the other hand, the carrier detection second switch means 13 is
Is detected, the electric motor 15 is placed in the deceleration waiting control state. Since the preceding carrier 7A has come out of the free roller section L ₂ , even if there is a delay with respect to the following carrier 7 like the above-mentioned carrier 7A, similar control is performed, and the carrier 7A
Can be received by the next claw body 9.

〔The invention's effect〕

According to the present invention, even if the electric motor for driving the carrier-conveying chain conveyor is provided separately from the main drive source for driving the driving pulley, the variation interval of the carriers for gripping and operating the rope is Is surely canceled after one round trip, and is repaired at a predetermined interval. Then, the power-driven mechanism in the automatic circulation type cableway can be simplified to suppress the construction cost from rising and to reduce the maintenance and inspection work.

When the free roller means, the claw body detection first switch means, the carrier detection first switch means, and the deceleration command control means are provided as the invention of the apparatus, the above-described operation is achieved.

If the deceleration command control means 14 is provided with a speed recovery command section and the claw body detection second switch means is also provided, the speed of the claw body is recovered by the signal from the claw body detection second switch means, and the carrier is carried. It is possible to speed up the receipt of the carrier by the transfer chain conveyor.

Further, if the deceleration command control means is also provided with a deceleration waiting control restart command part and the carrying device detection second switch means is installed, the carrying device whose second carrying device detection second switch means is received by the claw body,
The pawl body is kept at the original speed until it is detected at the downstream position after passing through the free roller section, and it is possible to avoid delaying the pushing of the carrier in the free roller section due to the delay of the subsequent carrier. However, after the carrier detection second switch means detects the carrier, it enters a deceleration waiting control state that enables deceleration control of the carrier conveyor chain conveyor, so even if there is a delay in the subsequent carrier, the same interval Corrective action can be taken. Therefore, the control for the preceding carrier and the control for the following carrier are not confused with each other, and the interval adjusting operation of the carrier is not confused.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings of the embodiments.

As shown in FIG. 1, the automatic circulation type cableway is, for example, a driving pulley 2 provided at a stop 1 at the foot of the mountain and a stop 3 at the summit.
(See FIG. 2) and the driven pulley 4 provided therein. A plurality of columns (not shown) are erected between the two stops 1 and 3, and a rope 5 supported by a rope attached to the columns is stretched endlessly.

The prime mover 2 is driven by a main drive source 6, and the rotation thereof causes the rope 5 to circulate between the foot of the mountain and the summit of the mountain. The transporter 7 suspended on the rope 5 has a gripping machine, and when it is accelerated in the acceleration section L ₃ on the departure side of each of the stops 1 and ₃ and the speed is synchronized with the rope 5, it is gripped and sent out. It is like this. That is, the carrier 7
When arrives at the stop 1 at the foot of the mountain, the carrier 7 is released and is decelerated by the deceleration rollers while moving along the rail 1b installed in the deceleration section L ₁ . When moving from the end of the deceleration section L ₁ to the free roller section L ₂ , it is slowly moved by the free roller 16a.

The moving speed of the cord 5 is about 4 m / sec, and the next carrier 7 passes every 6 seconds. From that 4 m / s, the speed is reduced to about 0.94 m / s in the deceleration section L ₁ , and about 0.46 in the free roller section L _2.
Dropped to m / sec.

The free roller section L ₂ faces the upstream end of the carrier conveyor chain conveyor 8 that is turned 180 degrees in order to transfer the arrived carrier 7 to the departure side.

The carrier conveyor chain conveyor 8 is provided with a plurality of claw bodies 9 and 9 for pushing the carrier 7, and a claw body detecting first switch means 10 and a claw body detecting second switch means for detecting the claw bodies 9. 11, transporter detection first switch means 12, transporter detection second switch means 13 is provided, the deceleration command control means 14 formed by a microcomputer or the like is installed in the drive control means 21 described later for adjusting the operation of the entire cableway. It

By the way, the driving pulley 2 for moving the rope 5 is driven by an electric motor as the main drive source 6. The rope 5 is maintained at a predetermined speed, but sometimes the speed is changed due to the operation of the carrier 7. Since the speed needs to be kept constant even if changed, a DC speedometer generator (not shown) is attached to the main drive source 6 to monitor the speed of the rope. On the other hand, a pulse generator (speed detector) 5c for detecting the moving speed of the carrier 7 is attached to one of the ropes 5a supporting the rope 5. As a result, pulses are generated by a large number of holes (not shown) arranged on the circumference formed in the rope 5a that rotates by the movement of the cord 5, and the number of pulses from the pulse generator 5c is input to the drive control means 21. It Based on the number of pulses, the drive control means 21 outputs a drive control signal for changing the speed of the carrier transporting chain conveyor 8 in proportion to the rope speed.
An output is provided for adjusting the drive speed of the electric motor 15 described below.

The above-described electric motor 15 for driving the chain conveyor 8 for carrying the carrier is provided independently of the main drive source for driving the driving pulley 2, and for driving the chain conveyor 8 for carrying the carrier, The power of the main drive source 6 is not received via the transmission mechanism. As the electric motor 15, an inverter motor, an inverter-controlled AC electric motor, a DC motor, or the like whose speed can be changed is adopted.
Such a motor 15 is also provided with a pulse generator (speed detector) 8b, and the feedback signal from the pulse generator 8b controls the motor 15 to a desired constant speed.

An endless chain 8a is stretched around the above-mentioned carrier conveyor chain conveyor 8, and the chain 8a that goes inside and outside is
A plurality of (10 in the figure) claw bodies 9, 9 are attached at a constant interval M ₁ . The chain 8a driven by the electric motor 15 has an arrow X.
In the free roller section 16 facing the free roller means 16 provided in the free roller section L ₂ . Therefore, the carrier 7 standing by in the free roller section L ₂ is carried away by the pushing by the claws 9 attached to the chain 8a around the free roller section ₂ and is transported to the departure side.

By the way, at the mountain top stop 3 (see FIG. 2), the same carrier transport chain conveyor 17 as the above carrier transport chain conveyor 8 is provided, but the number of claws 18 attached to it is extremely large. Its spacing M in the chain 17a
₂ is significantly shorter than the operation interval M ₁ of the carrier 7 (see the upper right part of FIG. 1). This does not have the function of adjusting the carrier interval described later like the carrier conveyor chain conveyor 8, and the carrier 7 that has arrived at the end of the deceleration section L ₁ is not caught by any of the claw bodies 18 that happen to be located near it. It simply allows them to be forwarded. Therefore, even if the interval between the carriers 7 and 7 is outside the predetermined range, they will be forwarded as they are. Further, even if a delay occurs due to the waiting state of the carrier 7 being prolonged due to getting off at the stop 3 at the summit or boarding operation, the carrier 7 is forwarded without correcting the interval with the preceding carrier 7. It should be noted that the carrier conveyor chain conveyor 17 is driven by an electric motor independent of the main electric motor 6 or by using the rotational force of the driven pulley 4 as in the case of the electric motor 15.

Returning to FIG. ₁ , in the free roller section L ₂ provided at the end of the deceleration section L ₁ , the free roller means 16 composed of a plurality of free rollers 16a, 16a is installed. As described above, the carrier 7 is transferred at a rate of about 0.94 to 0.46 m / sec, and waits until it is delivered to the predetermined claw body 9 of the carrier conveyor chain conveyor 8. However, since the carrier 7 comes into contact with the remaining free rollers 16a at the time when the carrier 7 starts to be pushed by the claw body 9, in any free roller 16a, the carrier 7 moves at the speed of the carrier conveyor chain conveyor 8. When it is forwarded, it can be individually rotated in synchronization with its speed.

The above-mentioned claw body detection first switch means 10 is for detecting that the claw body 9 of the transporter transporting chain conveyor 8 has reached the first predetermined position N ₁ up to the free roller section L ₂ for receiving the transporter 7. It is provided in. The first predetermined position N ₁ is provided in the illustrated inner circumference portion, and as will be described later, if the carrier transporting chain conveyor 8 maintains the current speed,
When the claw body 9 has passed the first predetermined position N ₁ , the claw body 9 has reached the predetermined approach position N ₂ in the deceleration section L ₁
Is selected at a position where it can be received in the free roller section L ₂ .

A photoelectric switch is used as the claw body detection first switch means 10, and when the claw body 9 passes the first predetermined position N ₁ , it is shielded from light and outputs a claw body detection signal. In addition,
A distance M between the claw body detection first switch means 10 and a claw body detection second switch means 11 provided at a second predetermined position N ₃ described later is set to be shorter than a constant interval M ₁ between the claw bodies 9, 9. ing.

The transporter detection first switch means 12 is provided to detect that the transporter 7 has passed the predetermined approach position N ₂ in the deceleration section L ₁ . This is, for example, a proximity switch, and if the pawl body 9 that has passed the first predetermined position N ₁ moves at the same speed, it can receive the carrier 7 that passes the predetermined entry position N ₂ in the free roller section L _2. The carrier detection signal shown is output.

The claw body detection second switch means 11 is a second predetermined position which is determined in the middle of the time when the claw body 9 of the carrier transporting chain conveyor 8 passes the first predetermined position N ₁ and reaches the free roller section L _2. It is provided to detect the passage of N ₃ . This is a photoelectric switch, which is shielded when the nail body 9A passes through the second predetermined position N ₃ and outputs a nail body detection signal.

The carrying device detection second switch means 13 is provided to detect the carrying device 7 received by the claw body 9 of the carrying device transporting chain conveyor 8 at the downstream position N ₄ after passing through the free roller section L ₂ . This uses a proximity switch and outputs a carrier detection signal.

When the deceleration command control means 14 receives the claw body detection signal from the claw body detection first switch means 10 and the carrier detection signal from the carrier detection first switch means 12, the deceleration command control means 14 maintains the rotation speed of the electric motor 15 and transports the carrier. The control for maintaining the speed of the chain conveyor 8 for the vehicle is performed, and the claw body detection signal from the claw body detection first switch means 10 is received, but the carrier machine detection signal is not received from the carrier machine detection first switch means 12. Sometimes an electric motor
It issues a command to decelerate 15.

When the claw body detection signal from the claw body detection second switch means 11 is received while the electric motor 15 is decelerated to move the carry machine forward chain conveyor 8 at a low speed, the movement of the carrier vessel transport chain conveyor 8 will be performed thereafter. It also has a speed recovery command unit 19 for returning to the original speed. Further, after the speed recovery command unit 19 returns the carrier conveyor chain conveyor 8 to the original speed, the deceleration control of the electric motor 15 can be performed until the carrier detection signal from the carrier detection second switch means 13 is received. While the deceleration waiting control to be prohibited is prohibited, after the carrier detection signal from the carrier detection second switch means 13 is received,
Deceleration wait control restart command section that enables 15 deceleration wait control
It also has 20.

In the automatic circulation cableway equipment with such a configuration,
You can adjust the 7 and 7 intervals as follows.

As shown in FIG. 1, the carrier 7 that has reached the departure side of the stop 1 at the foot of the mountain is accelerated in the acceleration section L ₃ , and when it reaches a speed in synchronization with the rope 5, it grasps the rope 5 and moves to the top of the mountain. Move towards stop 3 (see Figure 2). The carrier 7 that has started is sent out from the carrier conveyor chain conveyor 8 while maintaining a constant interval M _{1 of} 24 m from the preceding carrier 7. However, if there is a slight deviation during gripping, the vehicle will continue to operate with that deviation maintained.

While arriving at the summit stop 3 and getting off and boarding,
Some deviation occurs again. The carrier conveyer chain conveyor 17 has a large number of claws 18 at a narrow interval M ₂ , and is received by the claws 18 approaching immediately after the carrier 7 and pushed.
The carrier 7 turned 180 degrees is sent out through the acceleration section L ₃ . Even during that time, if there is a slight deviation in the gripping motion as in the above, the carrier 7 is sent out in a state in which all the deviations are overlapped. With such a gap between the carriers 7, 7, the carriers 7 sequentially return to the stop 1 at the foot of the mountain. In addition, in general, a deviation occurs that delays the arrival of the carrier 7.

Chain conveyor 8 for transporting the carrier at the stop 1 at the foot of the mountain
Is driven by an electric machine 15 and is operated at a chain speed that is approximately in proportion to the moving speed of the rope 5 by the main drive source 6 that drives the driving pulley 2. Now, when the claw body 9A moving at a constant speed passes the first predetermined position N ₁ as shown in the figure, the claw body detection first switch means 10 senses it, and the claw body detection signal is a deceleration command control means. Entered in 14.

At this time, the predetermined approach position N ₂ in the deceleration section L ₁ is set to the claw body 9A.
When the carrier 7A (indicated by a chain double-dashed line) to be received by the carrier passes, the carrier detection first switch means 12 senses the approach, and the carrier detection signal is input to the deceleration command control means 14.
The deceleration command control means 14 keeps the rotation speed of the electric motor 15 for driving the carrier conveyor chain conveyor 8 by receiving the pawl detection signal and the carrier detection signal. That is, it does not issue a command to shift the electric motor 15.

In such a state, the pawl 9A maintains the speed and moves to the free roller section L ₂ . On the other hand, the carrier 7A is also in the deceleration section
Exit L ₁ and enter free roller section L ₂ . Carrying device 7A is claw body
The free roller section L ₂ is entered prior to 9A, where it is further decelerated, and while moving at a slower speed, it waits until the pawl body 9A arrives. When the nail body 9A catches up with the carrier 7A, the nail body
9A is sent by receiving the carrier 7A.

The carrier 7A begins to be transported at the moving speed of the carrier transporting chain conveyor 8, but at that time, the carrier 7A (shown by a chain line)
Is still in the free roller section L ₂ . However, the free roller 16a, which is the free roller means 16, can be increased in rotation following the speed of the carrier 7A without any trouble. Then, the pawl 9A pushes the carrier 7A to turn it, and sends it to the acceleration section L ₃ .

On the other hand, if there is a delay in reaching the deceleration section L ₁ of the carrier 7A, the claw body 9A moving at a constant speed passes the first predetermined position N ₁ and the claw body detected by the claw body detection first switch means 10 is reached. Even when the detection signal is input to the deceleration command control means 14, the carrier detection signal that the carrier 7A has passed the predetermined approach position N ₂ in the deceleration section L ₁ is input from the carrier detection first switch means 12 to the deceleration command control means 14. Not done. At this time, the deceleration command control means 14
Issues a deceleration command to reduce the rotation speed of the electric motor 15. If the electric motor 15 is an inverter motor, frequency modulation control is performed, and if it is a DC motor, the supply current is reduced.

In such a state, the pawl 9A is decelerated to a predetermined speed and moves toward the free roller section L ₂ .
On the other hand, the carrier 7A does not have a large delay even if it is delayed, so the deceleration section L ₁ enters the free roller section L ₂ . Since the arrival of the claw body 9A is delayed, the carrier 7A enters the free roller section L ₂ before the claw body 9A, and thereafter, the carrier 7A is forwarded, turned, and delivered by the above-described operation.

When the speed reduction command control unit 14 is provided with the speed recovery command unit 19, the movement of the carrier transporting chain conveyor 8 is
The original speed can be restored automatically. That is, when passing through the second predetermined position N ₃ defined in the middle up to the free roller section L ₂ after pawl member 9A of carriage forward for chain conveyor 8 has passed the first predetermined position N _1, claw When the second detection switch means 11 detects it and receives the claw body detection signal, the speed recovery command section 19 thereafter issues a command to restore the carrier conveyor chain conveyor 8 to the original speed.

This is not a serious delay as described above even if there is a delay in the carrier 7A, so if the claw body 9A is temporarily moved slowly, the claw body 9A will be ahead of the carrier 7A even if the speed is returned thereafter. This is because the free roller section L ₂ is never entered. Conversely speaking, the distance for keeping the claw body 9 in the slow speed state can be predicted to the extent that it usually matches the delay of the carrier 7, and the second predetermined position N ₃ corresponding to it can be selected. In addition, when there is a great delay from the carrier 7 to the carrier 7A, it is detected by a zone detection device (not shown) provided in the deceleration section L ₁ , and it is judged to be an abnormal situation and the cableway equipment is stopped.

The above control is performed, but the deceleration command control means
When the deceleration waiting control restart command unit 20 is provided in 14, not only is the drive of the carrier conveyor chain conveyor 8 returned to the original speed, but also for the delay of the carrier 7A that arrives next. , The delay elimination operation can be reproduced quickly.

That is, the downstream position after passing through the free roller section L _2.
In N ₄ , when the carrier detection second switch means 13 detects the passage of the carrier 7A (shown by the three-dot chain line), the deceleration command control means 14 that has received the carrier detection signal, in the deceleration wait control restart command part 20, The electric motor 15 can be placed in a deceleration waiting state that enables subsequent deceleration control. On the other hand, unless the carrier detection signal is input from the carrier detection second switch means 13, the electric motor
The deceleration waiting control of 15 is prohibited so that the carrier 7A can be swiftly forwarded.

In addition, the control described above, at the site where the carrier moving facility is installed, if it is determined that it is not necessary after considering various conditions, operate the switch etc. for this control at that time, The control operation may be eliminated.

As can be seen from the above description, even if the electric motor for driving the carrier conveyor chain conveyor is provided separately from the main drive source for driving the prime mover, variations occur in the distance between the carriers that are operated by gripping the ropes. At this time, in the carrier conveyer chain conveyor at one of the stops, the distance between the carriers can be corrected to the original predetermined length. In addition, in this example, the example in which the carrier transporting chain conveyor that corrects the interval of the carrier is provided at the stop at the foot of the mountain has been described, but such a device may be provided at the stop at the top of the mountain. Needless to say.
