Abstract

PURPOSE:To prevent to grasp the rope at the splice part of a ropeway by a carrier starting from an intermediate station, by measuring the moving amount after the arrival of the carrier is detected, accelerating and transferring the carrier at a set moving amount, and making the carrier grasp the rope, when an intermediate station is provided in an automatic circulating type ropeway. CONSTITUTION:When a carrier 12a arrives at an intermediate station 4 positioning between a mountain foot station and a mountain top station, and separates a rope 11, and an arrival detecting switch (as) detects that the carrier 12a passes a rope separating position a, the rotation frequency of the rope receiving wheels 19 of a rope receiving device 17, that is, the moving amount of the rope, is converted into a pulse signal by a moving amount detecting device 22, so as to start the count. When the count value reaches the pulse number corresponding to the moving amount of the rope 11 up to an acceleration starting position b, a starting instruction is output from a starting instruction device, and an acceleration transfer device is driven to start the acceleration transfer of the carrier 12b waiting at the waiting position d. And when the speed of the carrier 12b at the rope grasping position c is made equal to the speed of the moving rope 11, the carrier 12b is made grasp the rope 11 at the rope grasping position, and start from the intermediate station 4.

SUMMARY OF THE INVENTION An object of the present invention is to prevent a carrier that departs from an intermediate stop from gripping a splice portion of a rope when an intermediate stop is provided in an automatic circulation type cableway. The purpose of the present invention is to propose a method for maintaining the interval between the carriers so as to prevent the carriers from staying at a specific stop by maintaining the interval between the carriers.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, an automatic circulating cableway is provided in an intermediate stop for unloading a line in which a carrier circulates and then gripping the line. An arrival detection switch for detecting that the transporter has passed through the line-releasing position in a transport section of the transporter that travels along the rail, and a movement amount detection device for measuring the amount of movement of the rope. , A departure detection switch for detecting a carrier that has been accelerated and transferred based on a command from the departure instruction device, and the measurement of the movement amount detection device is started by a signal from the arrival detection switch to set. When the moving amount is reached, the next starting carrier is accelerated and transferred at the command of the departure instructing device, and when the speed becomes equal to the above-mentioned rope, the arriving carrier again grasps the same position of the rope released and stops. Try to start from.

[0006]

[Function] Along with the track arranged at the intermediate stop of the automatic circulation type cableway, the arrival detection switch is located at the position where the carrier releases the line, and the rotation of the receiving wheel for guiding the circulating line is supported. It has a movement amount detection device that measures the amount of movement of the rope, a departure instruction device that commands the departure of the carrier when the movement amount reaches a set value, and a departure detection switch for detecting the departure carrier. .

Now, when a carrier arrives at the intermediate stop from the cableway line and shoots the rope, the arrival detection switch is activated and the movement amount detecting device starts counting the movement amount of the rope. Next, when the movement amount of the cord set by the movement amount detection device is reached,
The acceleration transfer device is activated in response to a command from the departure instruction device to start the accelerated transfer of the carrier waiting at the standby position. Further, when the carrier is accelerated and transferred at the same speed as the rope, the arriving carrier grips the portion of the rope released and departs from the intermediate stop. Further, the carriage that is accelerated and transferred is detected by the departure detection switch, and the movement amount of the cord measured by the above-described movement amount detection device is zeroed. In this way, the intervals of the carriers that have departed from the foothill stop and the summit stop are kept the same at the intermediate stop.

FIG. 2 shows the carriage 9 on the upstream side of the rails 9 and 10 arranged in the intermediate stop 4 described above.
The arrival of the carrier and the departure of the carrier 12b are shown. First, at the intermediate stop 4, a carrier 1 with a cord 11 released
In order to prevent the cord 11 moving at high speed from contacting the cords 2a and 12b, the cord receiving devices 17 and 18 configured by pivotally attaching a plurality of cords 19, 19 ... The rope 11 is supported and guided to a distant position. Further, the rails are arranged in a straight line so that the carriers 12, 12, ... Now, the carrier 12a arriving at the intermediate stop 4 releases the line 11 gripped at the release position a and runs on the rail 9 in the direction of arrow 13. The carrier 1 that has an arrival detection switch as using a photoelectric switch, a proximity switch, or the like near the rail 9 at the above-mentioned shooting position a and passes through the shooting position a
The cord 11 which the carrier 12a grips by detecting 2a
The gripping point AP of is specified.

Next, in order to electrically detect the amount of movement of the rope 11 which moves at a high speed in the intermediate stop 4, the one of the rope receiving devices 17 is provided with a movement amount detecting device 22. Get FIG. 3 shows the structure of the movement amount detecting device 22. That is, the rope receiving device 17 arranges the rope receiving beams 21 and 21 in parallel with the receiving ring 19 sandwiched therebetween, and fixes the shaft 20 in a horizontal state between the ropes. A detection piece RC is attached to one side surface of the receiving ring 19, and the beam receiving beam 21 is provided with a beam switch LB so as to react with the detection piece RC. The signal from the beam switch LB is input to the pulse counter CN. Next, as shown in the block diagram of FIG. 4, the numerical value of the pulse counted by the pulse counter CN is input to the comparator CC and compared with the set value, and if the counted value reaches the set value. If the comparator C
A signal is output from C and input to the departure instruction device 23, and an operation control device (not shown) is instructed to activate the acceleration transfer device.

Next, in the intermediate stop 4, a moving section length cl is set between the discharging position a and the gripping position c of the carrier 12, and an acceleration transfer section length is set between the waiting position d and the gripping position c. cdl. Next, as shown in FIG. 1, the cord 11 has a portion where a splice 11a is formed so as to be wound between the pulley 5 and the pulley 6 and connected endlessly. Partial line 1 in this section
A thicker part than the nominal diameter of 1 is created. If the carrier 12,1
The splice machine (not shown) for No. 2, ...
Gripping a has various effects on the cord 11 and the gripping machine (not shown). Therefore, the carrier 12,1
It is necessary for the gripping machines 2, 2 to operate the carriers 12, 12 without gripping the splice 11a.

FIG. 5 shows the carrier intervals when there is no splice 11a between the carrier 12a operating in the cableway 31 of FIG. 1 and the preceding carrier 12b. . Splice detection devices 30 and 30 are provided on the moving path of the rope 11 at the departure sides of the foothill stop 2 and the summit stop 3 shown in FIG. 1, respectively. When the splicing detector 30 or the splice detector 30 does not detect the splice 11a when the transporter 12 departs from the foothill stop 2 or the summit stop 3, a predetermined transporter interval hd1 (currently a passenger car type If the carrier is used, it will be 60 m.)
2, ... Departs. However, when the splice detecting device 30 detects the splice 11a, the carrier 12a is in between.
Since the departure of the vehicle is postponed, the starting carrier 12b and the succeeding carrier 12a expand to the illustrated carrier interval hd2.

Now, the splice detecting device 3 at the foothill stop 2
When the splice 11a is detected at 0 and the carrier interval is widened, the carrier 12, 12, which leaves the foothill stop 3 by an alternate departure interlocking device (not shown) in response to this.
... are also extended to the departure interval hd2 and the vehicles are departed so that the carriers 12, 12, ... do not stay at one of the stops. Therefore, also in the cableway line 31, the carrier 12a and the carrier 12b travel in the direction of the arrow 13 at the carrier distance hd2 and arrive at the intermediate stop 4.

FIG. 6 shows a rope locus LF along which the gripping point AP of the rope 11 gripped by the carrier 12b at the intermediate stop 4 moves.
3 is a graph showing a carrying locus CF of the carrying device 12 which starts next. Further, FIG. 7 is a plan view showing a time course in which the carrier 12a arrives at the intermediate stop 4 and the carrier 12a and the carrier 12b move when the carrier 12b departs.

A specific numerical example will be described below with reference to the graph shown in FIG. The horizontal axis of the graph represents the moving distance in the direction of the summit stop 3 with reference to the launch position a of the intermediate stop 4, and the vertical axis represents the passage of time. First, due to the mechanical arrangement of the intermediate stop 4, the moving section length cl of the rope 11 from the arriving position a to the gripping position c on the arrival side is 51.54 m. Next, the acceleration transfer section length cdl from the standby position d where the starting carrier 12b is on standby to the grip line position c is set to 10 m. In addition, the moving speed of the cord 11, that is, the carrying device 12, 1
The operating speed of 2, ... Is 5 m / sec.

Now, the time for the gripping point AP of the rope 11 gripped when the transporter 12 departs from the foothill stop 2 to move from the release position a to the gripping position c of the intermediate stop 4 is a movement section. The grip line start time ct obtained by dividing the long cl (51.54 m) by the operating speed of the transporter of 5 m / sec becomes 10.31 seconds. At this time,
The cord locus LF along which the gripping point AP moves is a straight line because the cord 11 circulates at a constant speed. Next, when the distance from the standby position d of the departing transporter 12b to the grip line position c is set to 10 m as described above, the transporter 12a waiting at the standby position d has the carrier 12a arriving at the gripping position c. The gripping point AP that was gripping in the cableway line 13 is accelerated and transferred so as to grip again. At the gripping position c, the moving speeds of the carrier 12b accelerated and transferred and the cord 11 are equal. The acceleration of the accelerating transfer device (not shown) is determined so that the time for accelerating and transferring the carrier 12b to the speed of the cord 11 is 3.79 seconds shown in the graph.

A horizontal line indicated by a chain double-dashed line is drawn on the time axis from the standby position d, and the intersection with the rope locus LF is set as the acceleration start position b. At this time, the acceleration start time bt (dt)
And Acceleration start position bl where the vertical line indicated by the chain double-dashed line and the horizontal axis indicating the distance intersect from the acceleration start position b
Will be 32.6 m. That is, when the gripping point AP, which the carrier 12a arriving at the intermediate stop 4 is gripping, moves 32.6 m from the release position a of the intermediate stop 4, the accelerated transfer of the next carrier 12b is started. This means that the carrier 12b can grip the gripping point AP of the cord 11 at the gripping position c. The carriages 12, 12, ... Standing at the gripping point AP of the carriages 12, 12, ... Arriving subsequently to the intermediate stop 4 at the waiting position d are accelerated and gripped at the gripping position c. The method will be described with reference to the flowchart shown in FIG.

First, as shown in FIG. 2, the arrival detection switch as detects that the carrier 12a that has arrived at the intermediate stop 4 and has released the rope 11 has passed through the emission position a. With this signal, the number of rotations of the receiving wheel 19 of the rope receiving device 17, that is, the moving amount of the cord 11 is replaced with a pulse signal by the moving amount detecting device 22, and counting is started. Further, a comparator CC is connected to the movement amount detection device 22, and here, the number of pulses corresponding to the movement amount of the cord 11 having the acceleration start length bl (32.6 m) at the acceleration start position b described above. Is set in advance, a signal is output to the departure instruction device 23 when the same value is reached, and an acceleration transfer device (not shown) is activated by a command from the departure instruction device 23 to move to the standby position d. Standby carrier 12
Start accelerated transfer of b. Further, at the same time as the speed of the cord 11 that moves to the grip line position c and moves to the grip line position c at the same time as the speed of the rope 11 that moves to the grip line position c, the grip line AP of the arrived carrier 12a reaches the grip line position c. The carrier 12b grips the gripping point AP and departs from the intermediate stop 4. When the departure detection switch ds provided in the acceleration movement section cdl described above detects the passage of the carrying device 12b that starts, the pulse counter CN of the moving amount detecting device 22 starts the next carrying device 1.
Reset the count number for 2.

As described above, according to the present invention, the intermediate stop 4
The carrier 12 that has been waiting is gripped and departed from the gripping point AP of the carrier 12 that has arrived at, so that the carrier interval of the cableway line 31 can be maintained even after passing through the intermediate stop 4. As shown in FIG. 5, even if the splice 11a is widened to the carrier interval hd2 so as not to grip the splice 11a,
Since the same portion of the cord 11 that has been released based on the carrier 12 is gripped, the starting carrier 12 does not grip the splice 11a. Therefore, it is not necessary to equip the intermediate stop 4 with the splice detection device 30. Further, since the arrived transporter 12 is detected and another standby transporter 12 is departed, the transporters 12, 12 are transferred to the intermediate stop 4. ,, ... will not be accumulated or, on the contrary, will not be insufficient.

INDUSTRIAL APPLICABILITY The present invention is applied to an automatic circulation cableway facility in which an intermediate stop is provided between a foothill stop and a summit stop to allow passengers to get on and off.

At this intermediate stop as well for passengers getting on and off,
The carrier grips and releases the lines that circulate, and accelerates, decelerates, and forwards the lines on the tracks provided in the intermediate stop. Therefore, it is necessary to properly maintain the carrier interval of the carriers that start at the intermediate stop as well.

According to the method, an arrival detection switch is provided at the arriving position on the arrival side of the intermediate stop, and the gripping point of the cord that the carrier is gripping is specified by the carrier. With the detection signal of this arrival detection switch, the movement amount detection device starts counting the amount of movement through the receiving ring, and when the gripping point reaches a predetermined position in the intermediate stop, it waits at the command of the departure instruction device. Start the acceleration of another transporter waiting at the position so that the gripping point of the above-mentioned cord will also come to the gripping position when it reaches the gripping position where it becomes the same speed as the moving cord. . That is, another starting transporter grips again the position of the line where the transporter arriving at the intermediate stop was gripping. In this way, the distance between adjacent carriers that have departed from the foothill and the summit stops is maintained even when passing through the intermediate stops.

Therefore, even if the splicing portion is detected by the splice detecting device provided at the foothill stop or the summit stop and the interval between the carriers is wider than the predetermined interval, the interval also passes through the intermediate stop. Being maintained, it is not necessary to have splice detection equipment at the intermediate stops. Further, since the arrived carrier is detected and the next carrier waiting is started, there is an effect that the carrier does not stay or run short at the intermediate stop.
