Description

  The present invention relates to a system for adjusting the number of transporting portable units in an automatic circulation type cableway, which adjusts the number of portable units operating in a track on an automatic circulation type cableway according to the actual number of transport passengers.

  Among the automatic circulation type cableway, the ski lift of a typical single-line automatic circulation type cableway is configured and operated as follows. That is, as shown in FIG. 5, pulleys 103a and 103b are pivotally provided at the stops 102a and 102b at both ends, respectively, and the rope 112 is wound endlessly between the pulleys 103a and 103b, and the cableway 101 It is stretched around. Main rails 104a and 104b for guiding the carrier 105 are arranged in the respective stops 102a and 102b so as to have a substantially U-shape in a plan view from the arrival side to the departure side of the carrier 105. Has been.

  The transporter 105 is a chair-type transporter in which a chair on which a passenger (skier) sits is suspended from a known gripper having a structure that allows the rope 112 to be seized freely. Grasping and operating along with the movement of the cable 112. When the transporter 105 arrives at one stop 102a, the grappler unloads the rope 100 and starts traveling while being guided by the main rail 104a and simultaneously decelerated by a speed reduction pusher (not shown). Then, it is forwarded at a slow speed by a forwarding push device (not shown), the direction of travel is turned 180 degrees, and the passenger (skier) gets on the transporter 105 at a predetermined boarding position. Subsequently, when the transporter 105 is accelerated by an acceleration pusher (not shown) and is at the same speed as the rope 112, the gripper of the transporter 105 grips the rope 112, and along with the movement of the rope 112 Depart into cableway 101. In the figure, only one carrier 105 is illustrated, but actually, a plurality or a plurality of carriers 105, 105,... Are used and operated one after another at predetermined intervals.

 In order to guide passengers to the stop 102a of the automatic circulation cableway 100 as described above, in the past, in the direction of the cableway line 101 that is generally guided from the rear of the stop 102a to the boarding position 108 to get on. This is an arrangement of the stop 102a in which the front-rear direction guidance method of the stop 102a is most often employed.

  The case of FIG. 5 shows the case of the front-rear direction guidance method in which the passenger is directed toward the cableway 101 with respect to the stop 102a. That is, at the stop 102a, a passenger approach lane 106 is provided on the extension line on the departure side of the transporter 105 in substantially the same direction as the cableway 101, and the passenger (skier) is guided in the direction of the arrow 107 to obtain a predetermined boarding. The user sits on the chair-type transporter 105 at the position 108 and gets on. When the transporter 105 on which the passenger (skier) gets on is operated along with the movement of the rope 112 in the cableway 101 and arrives at the other stop 102b, the gripper of the transporter 105 travels on the main rail 104b almost at the same time. At the disengagement 109 provided at a predetermined position on the passenger exit lane 110 after the grinder disengages the rope 112 and is decelerated to a forwarding speed at which a passenger (skier) can get off by a deceleration pusher (not shown). A passenger (skier) gets off the transporter 105. Passengers (skiers) who get off from the transporter 105 quickly move in the passenger exit lane 111 in the direction of the arrow 110 so as not to be pushed from behind by the transporter 105 that has become unoccupied and becomes empty, and exit from the other stop 102b.

 As mentioned above, the automatic recirculating cableway ski lift that transports passengers (skiers) has higher transport capacity than conventional ski lifts, and is used at ski areas that are particularly crowded because of its high speed and long ski runs. Has been. Moreover, the thing equipped with the chair for 3 to 8 persons is employ | adopted for the transporter 105. FIG. (See FIG. 6 of Patent Document 1)

The control device operates the branch point, the merging point, and the standby forwarding push device to enter and exit the standby device from the standby rail. The transporter is adjusted by the device to the transporter interval calculated by the control device.

  Further, the boarding number counting means detects the passenger with a boarding restriction device that controls whether or not the passenger enters the boarding position of the stop, and obtains the transport amount by counting with a counter.

  Further, the boarding number counting means measures the power consumption per predetermined time of the electric motor that operates the transporter with a power accumulator to obtain the transport amount.

  According to the present invention, by calculating and operating the number of carriers required for transportation from the actual transportation results in a predetermined time on the automatic circulation cableway, the power consumption is reduced by reducing the number of carriers operated by empty vehicles as much as possible. In addition, there is an effect that the service life of the cableway equipment can be extended because the number of operations of each carrier can be reduced and the fatigue and wear of the members constituting the gripping machine can be reduced.

  Next, in a section curved in a “U” shape in plan view of the forwarding rail 7, the passenger gets on the operation carrier 5 a in a section in which the operation carrier 5 a turns in a direction perpendicular to the cableway 2 and passes. The boarding position 32 to be set is set, and in the upper part in the plan view, the boarding position 32 is routed to the boarding position 32 in a straight line toward the direction of the arrow 69, and is forwarded to the traveling carriage 5 a and the standby rail 8. The boarding | limiting control apparatus 30 which provided the distance which does not contact with the standby carrier 5b is installed. The boarding restriction device 30 has the same number of gates 31 as the boarding capacity of the transporter 5, and includes a bar or an arm that can be turned in the horizontal direction by a motor or the like for each gate 31, so that the passenger moves the moving rail 6. Appropriateness of entry to the boarding position 32 is restricted so as not to contact the transporter 5a. The boarding restriction device 30 has a structure well known to those skilled in the art.

  Subsequently, the boarding restriction device 30 is provided with a counter 41 that counts the number of opening / closing operations of the gate 31 based on the number of passengers passing toward the boarding position 32 in the direction of the arrow 69, and inputs the count value to the control device 40. In addition, the electric motor 23 that rotationally drives the driving pulley 21 is connected to a power integrator 42 that detects the power consumption of the electric motor 23, and inputs the count value to the control device 40. Further, an operation command is output from the control device 40 to each branch point 16 and junction point 17.

  Next, an operation method of the transporters 5, 5,... By the automatic transport cableway operation transporter number adjusting system of the present invention whose configuration has been described above will be described with reference to FIGS. FIG. 2 shows the arrangement or situation of the carriers 5, 5,... Passing through the foothill stop 4 when all the carriers 5, 5,. In this state, the standby rail 8 does not have the standby carriers 5b and 5b, the branch point 16 and the junction point 17 are connected to the forward rail 7 side, and move at a low speed or a slow speed by the forward transfer device 11 from the direction of the arrow 63. Passing through the boarding restricting device 30 and proceeding in the direction of the arrow 69 to the boarding position 32, passengers waiting at the boarding position 32 get on the incoming transport vehicles 5a, 5a,.

  After that, it passes through the junction point 17 to the departure side main line rail 9, the distance between the forward traveling carrier 5a is adjusted by the carrier interval adjusting device 12, and the traveling carrier 5a on which the passenger gets on is a well-known acceleration pushing device 13.

From the total number of carriers from the transport amount for a predetermined time set in the control device 40 by the forwarding push device 11 and the standby push device 14. 5b,... Is detected by the warehousing / detecting device detector 43 and is made to wait on the standby rail 8. Note that when the vehicle is discharged from the standby rail 8, the standby carrier 5 b that is waiting on the standby rail 8 due to the difference in the number of times of detection between the storage device detector 43 and the storage device detector 44 is detected by the storage device detector 44. The number of will be revealed.

  FIG. 4 shows a situation in which the operation is resumed by reducing the number of operation vehicles 5a, 5a,... After waiting the standby vehicles 5b, 5b,. In the standby rail 8, standby carriers 5 b, 5 b,... That exceed the number of operation carriers 5 a, 5 a,... Set according to the transport amount by the control device 40 are forwarded and stored. Thereafter, the standby operation of the automatic circulation cableway 1 is stopped. Subsequently, the branch point 16 is switched to the forward rail 7 to connect the arrival side main rail 6 and the forward rail 7, and the junction point 17 is also switched to the forward rail 7 to connect the forward rail 7 and the departure side main rail 9. . In addition, the boarding restriction device 30 is also restarted to restrict passengers from entering the boarding position 32 and to start counting passengers. Subsequently, the prime mover 20, the deceleration pusher 10, the forward pusher 11, the transporter interval adjustment device 12, and the acceleration pusher 13 are restarted. Thereafter, the controller 40 instructs the carrier interval adjusting device 12 so that the intervals between the operation carriers 5a, 5a,... , 5a,..., 5a,..., When the acceleration pusher 13 accelerates to the speed equal to the speed of the rope 3 in the direction of arrow 66, the transporters 5a, 5a,. Search and go to the summit stop in the direction of arrow 67.

  In the above, the transport amount of the automatic recirculating cableway 1 was calculated by detecting passengers passing through the gate 31 of the boarding restriction device 30 and counting them with the counter 41. However, per predetermined time of the motor 23 that drives the driving pulley 21 It is also possible to calculate the transport amount by measuring the power consumption of the power by the power integrator 42.

  When increasing the number of operation vehicles 5a, 5a,..., The standby vehicles 5b, 5b,... Accommodated in the standby rail 8 shown in FIG. After transporting and adjusting the carrier interval of all the operation vehicles 5a, 5a,...
