Abstract

PROBLEM TO BE SOLVED: To provide a speed control device of a cross type cableway, having a plurality of operation patterns with different set speeds and capable of safely control the speed of each of carriers when the set speeds are switched and used during operating the carriers.SOLUTION: The speed control device includes carriers 16 towed by the cable 13 between stops so as to reciprocate, an electric motor 19 for driving the cable 13, a driving device 20 for supplying power to the electric motor 19 and driving the electric motor 19, and a controller 22 for outputting a control signal to the driving device 20 on the basis of a plurality of selectable speed patterns. Different set speeds and a speed reduction starting position in each of the set speeds are set in the operation speed patterns respectively.

Description

  The present invention relates to a speed control of a crossing type cableway that controls the operation speed of the carrier in a crossing type cableway that suspends a carrier on a cable straddling between the stops and reciprocates between the two stops. It relates to the device.

  A crossing type cableway is a cableway facility with a system in which one or more ropes are stretched between the stops, the carrier is suspended, and the carriage is pulled between the two stops by the rope. In this crossing type cableway, the carriage is operated as follows. First, at the stop, the transporter is stopped, and passengers get on and off in this state. When boarding / exiting is completed, the transporter departs the stop at a very low speed and then accelerates to a predetermined operating speed. After reaching a certain speed, the transporter moves while maintaining this speed in the cableway. Thereafter, when the transporter reaches the vicinity of the other stop, the transporter decelerates, enters the stop at a very low speed, stops, and passengers get on and off again.

  Such speed control of the transporter is generally performed as follows. Pulleys are pivoted at the respective stops, and the ropes that pull the carrier are wound between the pulleys. An electric motor is connected to any one of these pulleys via a speed reducer, and when this pulley is driven to rotate by the electric motor, a rope wound around the pulley is driven to move through the track. The transporter moves as it moves.

  A speed detector that detects the rotational speed of the motor and transmits an electrical signal is connected to the motor. On the other hand, the pulley that drives the rope or the pulley that guides the rope at the stop is provided with a rope movement amount detector that detects the number of rotations of the pulley and transmits a signal. Signals from the speed detector and the rope movement amount detector are input to a controller that controls the speed of the rope or the carrier, and the speed of the rope and the movement amount of the rope are calculated from each signal. The controller stores an operation speed pattern that determines the speed of the carrier between the stops, and the control speed of the cable corresponding to the calculated movement amount of the cable is derived from the operation speed pattern. The control speed is compared with the actual rope speed detected from the electric motor to perform feedback control of the electric motor (see, for example, Patent Document 1).

  With such a configuration, the normal operation is performed automatically as follows. First, when the operation speed of the transporter is set by the speed selection switch, an operation speed pattern that matches the operation speed is set in the controller in response to this signal. Next, by operating the operation start button, the controller performs feedback control of the electric motor based on the operation speed pattern as described above, so that the rope is accelerated, decelerated, or constant speed at a predetermined position. Operates automatically between bus stops. When the transporter arrives at the stop and stops, the rope movement information in the controller is reset and prepared for the next operation.

  In addition to such an automatic driving method, a semi-automatic driving method may be adopted. In semi-automatic operation, for example, a driving master panel is equipped with a tiltable master controller, and the controller controls the motor at a variable speed in response to the tilt angle signal. The speed is compared with the speed pattern, and control is performed so that the rope speed does not exceed the speed of the driving speed pattern.

JP 7-277180 A

  The driving speed pattern set in the above controller is generally set with multiple driving patterns with different maximum operating speeds (set speeds) so that it can correspond to the operating conditions such as weather conditions and the number of passengers to be used. The driving operation panel is provided with a speed selection switch for selecting an operation speed, and an appropriate operation speed is selected by this operation so that the operation panel is automatically operated at an operation speed corresponding to the situation. The above speed selection switch can be switched even during operation, for example, when the lateral movement of the carrier is large, the speed selection switch is switched when the carrier passes through the column, and the operation speed is lowered to pass through the column position. Then, after that, it is possible to operate again by switching to the high speed side and operating at high speed.

  An object of the present invention is to provide a speed control of a crossing cableway that can safely control the speed of a transporter when such a plurality of operation patterns having different set speeds are used and switched during operation of the transporter. To provide an apparatus.

  Based on a carrier that is pulled and reciprocated by a rope between stops, an electric motor that drives the rope, a driving device that supplies electric power to the electric motor, and a plurality of selectable operation speed patterns A controller that outputs a control signal to the drive device, and the operation speed pattern is set with different set speeds and deceleration start positions corresponding to the set speeds, and the set speeds are switched in the vicinity of the deceleration area. In this case, the speed control of the transporter is performed by comparing the deceleration start position in the operation speed pattern after switching with the current position of the transporter.

  According to a second aspect of the present invention, in the speed control device according to the first aspect, when the set speed is switched at a position where the position of the transporter does not reach the deceleration start position in the operation speed pattern after the switching. When the speed of the transporter reaches the deceleration start position in the operating speed pattern after the switching before reaching the set speed after the switching, the transporter decelerates from the deceleration start position in the operating speed pattern after the switching. Control the speed as follows.

  Further, the invention according to claim 3 is the speed control device according to claim 1 or 2, wherein the position of the carrier is the position after passing the deceleration start position in the operation speed pattern after switching. When the set speed is switched, speed control is performed so that the transporter is decelerated simultaneously with the switching of the set speed.

  According to the present invention, when the set speed is switched during operation, the speed control is performed based on the deceleration start position in the operation speed pattern after the switching. Since it is controlled so as to be the same position as the deceleration end position when the set speed is not switched or a position earlier than that, the transporter can be safely operated even if the set speed is switched during operation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the entire crossing cableway. A branch 12 is stretched between the summit stop 10 and the summit stop 11, and the end of the support 12 on the side of the summit stop 11 is fixed to a concrete foundation or the like. A branch weight 14 is suspended from the end portion on the 10 side to keep the tension of the branch 12 constant. A carrier 16 is suspended and supported on the support 12, and the transporter 16 moves along the support 12.

  The cable 13 is endlessly circulated and stretched between the foothill stop 10 and the summit stop 11, and is turned around by the guide pulley 24 provided at the summit stop 11 and wound around the driving pulley 17. It is rotated, and this driving pulley 17 is driven in rotation to move in the track. A transporter 16 is fixed to the cable 13, and the transporter 16 is operated along with the movement of the cable 13. In addition, the erection weight 15 is suspended from the erection 13 at the foothill stop 10, and a constant tension is applied to the erection 13 so that the operation of the transporter 16 is stably performed. And these support line 12 and the cable 13 are supported by the support | pillar 23 standingly arranged in the track.

  An electric motor 19 is mechanically connected to the driving pulley 17 via a speed reducer 18, and the electric motor 19 rotates at a variable speed by supplying electric power from a driving device 20. A controller 22 is electrically connected to the driving device 20, and the driving device 20 supplies electric power suitable for the electric motor 19 by the speed reference signal transmitted from the controller 22 to drive the driving device 20. On the other hand, the guide pulley 24 is provided with a movement amount detector such as a synchro-transmitter that operates along with the rotation of the guide pulley 24 to detect the movement amount of the cable 13, and the signal of this movement amount detector is sent to the controller 22. Entered. As shown in FIG. 2, the controller 22 stores and sets a movement speed pattern indicating a movement distance of the carrier 16, that is, a correspondence relationship between the movement distance of the cable 13 and the movement speed. A speed reference signal is output based on this driving speed pattern.

  Next, the operation of the speed control device having the above configuration will be described. In the operation speed pattern of FIG. 2, the speed of the transporter 16 is represented in the vertical axis direction, and the movement distance is represented in the horizontal axis direction. When an automatic operation start signal is input to the controller 22 by operating a driving operation panel (not shown), the controller 22 transmits a speed reference signal of the fine speed 51 to the driving device 20, thereby rotating the electric motor 19. Then, the transporter 16 departs from the stop starting position 53 at a slow speed 51. At the same time, the controller 22 continuously calculates the movement amount of the cable 13, that is, the movement amount of the transporter 16, based on the signal from the movement amount detector, and collates the calculated movement distance value with the driving speed pattern.

  When the movement distance value calculated in the controller 22 reaches the acceleration start position 57 in the driving speed pattern, the controller 22 outputs a signal so that the rotation speed of the electric motor 19 is increased. The carrier 16 is accelerated by increasing the rotation speed. Next, when the movement distance value calculated in the controller 22 reaches the acceleration end position 54, the controller 22 outputs a signal so that the rotation speed of the electric motor 19 becomes a constant rotation, whereby the driving device 20 causes the electric motor 19 to be turned off. The carrier 16 is rotated at a constant rotational speed and proceeds through a set speed section 68 at a constant speed 52.

  Thereafter, when the movement distance value calculated in the controller 22 reaches the deceleration start position 55, the controller 22 outputs a signal so that the rotation speed of the electric motor 19 decreases, whereby the driving device 20 rotates the rotation of the electric motor 19. The carrier 16 is decelerated by lowering the number. Next, when the movement distance value calculated in the controller 22 reaches the deceleration end position 58, the controller 22 outputs a signal so that the rotation speed of the electric motor 19 becomes a slow rotation, whereby the driving device 20 causes the electric motor 19 to be turned off. After the carrier 16 is rotated at the slow speed and the carrier 16 travels at the slow speed 51, for example, a detector such as a limit switch provided in the stop detects that the carrier 16 has reached the stop position 56, and this signal causes the controller 22 to A stop signal is transmitted to stop the transporter 16 and the distance value calculated in the controller 22 is preset. Thus, the operation of one stroke is completed, and thereafter, the operation is repeated in the same stroke.

  The controller 22 is provided with a plurality of driving speed patterns having different speeds in the set speed section 68, and a driving speed pattern suitable for the driving situation is selected by a speed selection switch provided on a driving operation panel for instructing driving of the cableway. Then, the transporter 16 is operated. The plurality of operation speed patterns set in the controller 22 can be switched even during operation of the transporter 16, and the control when the operation speed pattern is switched during operation will be described below.

  FIG. 3 is a diagram showing operation speed patterns in the vicinity of the deceleration region where the transporter 16 approaches the stop position 56 and decelerates. In the figure, three types of operation speed patterns having different speeds in the set speed section 68 are shown in the same figure. Shown in. Each driving speed pattern includes a first set speed 61 in which the set speed section 68 has a high constant speed 52, a second set speed 62 in which the set speed section 68 has a slightly lower constant speed 52a, and further setting. The third set speed 63 having a constant speed 52b in which the speed of the speed section 68 is low is set, and the same deceleration curve 59 is applied in any driving speed pattern, and the deceleration end position 58 and the stop position 56 are the same. Position. Further, since the speeds of the respective set speed sections 68 are different, the deceleration start positions corresponding to the first set speed 61, the second set speed 62, and the third set speed 63 are the first deceleration in order of increasing distance from the stop position 56. A start position 55, a second deceleration start position 55a, and a third deceleration start position 55b are provided.

  FIG. 4 shows speed control when the second set speed 62 is switched during operation at the third set speed 63. In the figure, when the driving speed is switched from the third set speed 63 to the second set speed 62 at the speed switching position 64, the controller 22 performs control so as to accelerate the transporter 16 at the set acceleration, and at the same time the second set speed 62. By applying the operation speed pattern of the set speed 62, the deceleration start position is set to the second deceleration start position 55a. When the speed of the transporter 16 increases and reaches the constant speed 52a of the second set speed 62, the acceleration is stopped and the transporter 16 is advanced at the constant speed 52a. Thereafter, when the position of the transporter 16 reaches the second deceleration start position 55a of the second set speed 62, control is performed so that the speed of the transporter 16 decreases along the deceleration curve 59, and the transporter 16 reaches the deceleration end position 58. Then, the vehicle proceeds at a slow speed 51 and stops at a stop position 56.

  FIG. 5 shows speed control when the first set speed 61 is switched during operation at the third set speed 63. In the figure, when the driving speed is switched from the third set speed 63 to the first set speed 61 at the speed switching position 64, the controller 22 performs control to accelerate the transporter 16 at the set acceleration, and at the same time, the first The deceleration start position is set to the first deceleration start position 55 by applying the operation speed pattern of the set speed 61. When the transporter 16 proceeds with acceleration, the transporter 16 reaches the first deceleration start position 55 before the speed of the transporter 16 reaches the constant speed 52 of the first set speed 61, and the controller 22 causes the transporter 16 to move from this position onward. Control to slow down. The deceleration at this time is set to be the same as the deceleration of the deceleration curve 59. Therefore, the position where the deceleration ends is farther from the stop position 56 than the normal deceleration end position 58. Therefore, although the operation time is slightly longer, it operates on the safety side.

  FIG. 6 shows speed control when the transporter 16 is switched from the third set speed 63 to the first set speed 61 after passing the first deceleration start position 55 of the first set speed 61. In the figure, when the driving speed is switched from the third setting speed 63 to the first setting speed 61 at the speed switching position 65, the driving speed pattern of the first setting speed 61 is applied to the controller 22 so that the deceleration start position is the first. One deceleration start position 55 is set. The controller 22 compares the position of the first deceleration start position 55 with the position of the speed switching position 65, and detects that the position of the speed switching position 65 exceeds the position of the first deceleration start position 55. Then, control is performed to immediately reduce the speed of the transporter 16. The deceleration at this time is set to be the same as the deceleration of the deceleration curve 59 in the same manner as described above. Therefore, the position where the deceleration ends is farther from the stop position 56 than the normal deceleration end position 58. It will be a position, and this will slightly increase the operation time, but it will act on the safety side in operation.

  In the above description, the control when the constant speed is switched from the low speed side to the high speed side has been described. Hereinafter, the case where the constant speed is switched from the high speed side to the low speed side will be described. FIG. 7 shows the speed control when switching to the second set speed 62 during operation at the first set speed 61. In the figure, when the operation speed is switched from the first set speed 61 to the second set speed 62 at the speed switching position 66, the controller 22 performs control to decelerate the transporter 16 at the set deceleration, and at the same time, By applying the operation speed pattern of the two set speeds 62, the deceleration start position is set to the second deceleration start position 55a. The deceleration at this time is set to be the same as the deceleration of the deceleration curve 59 as described above. When the speed of the transporter 16 decreases and reaches the constant speed 52a of the second set speed 62, the deceleration is stopped and the transporter 16 is advanced at the constant speed 52a. Thereafter, when the position of the transporter 16 reaches the second deceleration start position 55a of the second set speed 62, control is performed so that the speed of the transporter 16 decreases along the deceleration curve 59, and the transporter 16 stops at the deceleration end position. After 58, the vehicle travels at a slow speed 51 and stops at a stop position 56.

  FIG. 8 shows the speed control when the transporter 16 is switched to the second set speed 62 after passing the first deceleration start position 55 of the first set speed 61 when operating at the first set speed 61. ing. In the figure, the speed switching position 67 is a position where the transporter 16 is decelerating along the deceleration curve 59. When the operation speed is switched from the first set speed 61 to the second set speed 62 at this position, the controller 22 performs control to decelerate the transporter 16 at the set deceleration, and at the same time, the second set speed 62 By applying the operation speed pattern, the deceleration start position is set to the second deceleration start position 55a, and the deceleration control is continued until the transporter 16 reaches the second deceleration start position 55a. Since the deceleration at this time is set to be the same as the deceleration of the deceleration curve 59 as described above, the deceleration curve 59 is in a continuous state, that is, the same curve as when the set speed is not switched, In this case, deceleration is performed in the same state as when the set speed is not switched even if the set speed is switched.

  As mentioned above, although demonstrated from specific embodiment, invention of this application is not limited only to said specific embodiment. That is, in the speed control device of the present invention, when a plurality of speed patterns set in the controller 22 are switched during operation, the subsequent speed control is performed in the switched driving pattern and the driving pattern. This is performed based on the deceleration start position, and the relationship between operation patterns that are switched to each other corresponds to one of the above embodiments.
