It is forwarded at a slow speed by the forwarding and pushing device 6, during which passengers get on and off. Next, the transporter 4 sent to the departure side is accelerated to the same speed as the speed of the rope 1 by the acceleration pushing device 7 in the acceleration section K, grasps the rope 1 in the speed tuning section D, and enters the cableway line. And depart.

In such a system, a pulley is attached to each of the rubber tire wheels 8, 8,..., And a belt is wound between pulleys adjacent to each other to continuously and continuously transmit the driving force.

FIGS. 6 and 7 show a side view and a front view of the accelerating and pushing device 7 and the decelerating and pushing device 5, respectively. In FIG. 6, a rubber tire wheel 8, a large pulley 9, and a small pulley 1 are shown.
Numeral 0 is fitted on the same axis and is pivotally supported by the pushing frame 11 so that the large pulley 9 or the small pulley 10 is driven to rotate the rubber tire wheel 8.

In FIG. 7, a belt 13 is wound around the large pulley 9 with a small pulley 10a adjacent to one side, while the small pulley 10 is wound with a large pulley 9a adjacent to the other side. The belt 13 is wound. The belts 13, 13,...

However, in such an arrangement relationship of the rubber tire wheels 8, 8,...
Although temporarily, the two rubber tire wheels 8, 8 simultaneously contact the towing machine 12, and the rotational speeds of these two rubber tire wheels 8, 8 are different, so that either one or both rubber tire wheels 8, 8 are different. A slip has occurred between the rubber tire wheel 8 and the rope rig 12. Such a slip causes adverse effects such as promoting abrasion of the contact surfaces of the rubber tire wheels 8 and the rope rig 12 and causing a loss of driving force.

Embodiments of the present invention will be described below with reference to the drawings. In this description, the arrangement of devices and the like at the stop other than the acceleration / deceleration / push-off device is the same as that described in the related art, and the description is omitted. FIG. 1 is a front view showing the overall configuration of the acceleration / deceleration pushing / running device 22 of the present invention. The traveling rail 20 is provided in an elevated manner at the stop, and the carriage 21 rolls on the traveling rail 20. An acceleration / deceleration pushing device 22 for accelerating or decelerating the transporter 21 is provided at an upper portion along the traveling rail 20. The acceleration / deceleration pushing device 22 operates as a deceleration pushing device that reduces the speed of the carrier when the carrier 21 arrives from the cableway line 23 in the direction of arrow A, and when the carrier 21 departs to the cableway line 23 in the direction of arrow B. It operates as an acceleration pushing device for accelerating the speed of the transporter.

The acceleration / deceleration pushing device 22 has a plurality of rubber tire wheels 25, 25,... Arranged at regular intervals, and rotates the rubber tire wheels 25, 25,. By driving, the towing machine 24 or the carrying device 21 is transferred. FIG. 2 is a sectional side view of the acceleration / deceleration pushing device 22. The rubber tire wheel 25 is fitted and fixed to one end of a shaft 27, and a pulley 28 formed with two belt grooves having the same pitch diameter is fitted and fixed to the other end. The shaft 28 is pivotally supported by a pushing frame 29,
The rubber tire wheel 25, the shaft 27 and the pulley 28 rotate integrally. Belt 3 on pulley 28
0, 30 are wound around these belts 30, 3,
Numeral 0 is wound around pulleys 28, 28 adjacent to each other in front and rear. In this way, all the pulleys 28, 28,... Adjacent to each other are connected by the belt 30, and by driving any one of the pulleys 28 or the belt 30, all the pulleys 28, 28,. , 25, ... are driven at the same rotational speed.

Next, one of the combinations of the pulleys 28 and the rubber tire wheels 25 serves as an input unit of a driving force for rotationally driving the rubber tire wheels 25, 25,.... FIG. 3 shows a side view of the input unit. A drive motor 31 capable of controlling the rotation speed is fixed above the pushing frame 29, and the rotation speed is controlled by a control device (not shown) described later. A drive pulley 32 is fitted on the output shaft of the drive motor 31. On the other hand, a driven pulley 33 is formed or fixed outside the pulley 28 located below the driving pulley 32, and a driving belt 34 is wound around the driven pulley 33 and the driving pulley 32 and connected. ing.

In the driving force input section configured as described above, the driving motor 31 is driven at a variable speed, and the driving pulley 3 is driven.
2. Drive the pulley 28 or the rubber tire wheel 25 via the drive belt 34 and the driven pulley 33. As described above, the pulley 28 is connected to the adjacent pulleys 28 and 2.
8,... And therefore the drive motor 3

... or rubber tire wheels 25, 25, ... are driven at the same rotational speed. In the configuration described above, the driving force of the driving motor 31 is transmitted by the driving belt 34.
Pulley 2 by transmission method such as chain or universal joint
8 can be directly driven.

Next, at both ends of the accelerating / decelerating and pushing device 22,
As shown in FIG. 1, there are provided carrier detection sensors 26a and 26b for detecting the carrier 21, and when the carrier 21 has passed, it is detected and a detection signal is transmitted to the control device.

The operation of the thus configured acceleration / deceleration feeding device 22 will be described separately for the case of operating as an acceleration feeding device and the case of operating as a deceleration feeding device. First, a case where the apparatus operates as an acceleration pushing device will be described.

When the transporter 21 is being transported at a slow speed by the transporting / feeding device 6 in the entry / exit section J, the acceleration / deceleration feeding device 2
2 is driven at the same speed as the driving speed of the feeding and feeding device 6. The speed signal of the cable is always input to the control device of the drive motor 31, and an appropriate acceleration curve is calculated from the difference between the transport speed and the cable speed in the section J of the carriage 21. The acceleration curve shows the correspondence between the passing position of the transporter 21 and the speed of the transporter 12 or the rotation speed of the rubber tire wheel 25 at that time. It indicates an optimum speed change until the speed is reached, and is actually stored as numerical data in the control device.

When the transporter 21 enters the acceleration / deceleration pushing device 22, the transporter detection sensor 26a detects the transporter 21 and sends a detection signal to the controller of the drive motor 31. The control device that has received the carry-out detection signal starts control so that the rotation speed of the drive motor 31 increases with time based on the acceleration curve described above. The transporter 12 that has entered the controlled acceleration / deceleration feeding device 22 is accelerated as the traveling speed of the rubber tire wheels 25, 25,. At the exit position, the speed is the same as the speed of the rope. After this,
The handgrip machine 24 grasps the cable and departs to the cableway track 23. Thereafter, the drive motor 31 is again moved to the transporting / feeding device 35.
Are driven to the same speed as the driving speed of the carriages 21, and the transporters 21, 21,.

Next, a case where the acceleration / deceleration feeding device 35 operates as a deceleration feeding device will be described. When the carriage 21 is suspended from the rope and enters the stop from the cableway 23, the carriage 21
Of the handgrip 24 moves on the traveling rail 20 to release the rope. At this time, the rubber tire wheel 2 of the acceleration / deceleration pushing device 22
The rotation speeds of 5, 25,... Are driven at a rotation speed at which the transporter 21 is transported at the same speed as the speed of the cords. In the control device of the drive motor 31, a deceleration curve is calculated in a manner opposite to that of the above-described acceleration pushing device. The deceleration curve is similar to the acceleration curve in that the passing position of the transporter 21 and the transporter 12 at that time are shown.
And the rotation speed of the rubber tire wheels 25, and shows the optimal speed change from when the transporter 21 reaches the speed of the rope at the deceleration start position to the transport speed at the deceleration end position.

When the transporter 21 enters the acceleration / deceleration pushing device 22, the transporter detection sensor 26b detects the transporter 21 and sends a detection signal to the controller of the drive motor 31. The control device that has received the carry-in detection signal controls the rotational speed of the drive motor 31 to decrease with time based on the deceleration curve. The transporter 12 that has entered the controlled acceleration / deceleration feeding device 22 is decelerated as the traveling speed of the rubber tire wheels 25, 25,. At the exit position 35, the speed is the same as the forwarding speed. After this, transporter 2
When 1 is delivered to the feeding and pushing device 35, the drive motor 31 is again driven at a rotational speed that transfers the same speed as the speed of the rope, and thus the transporters 21, 21,. Slow down.

[0022]

As described above, the accelerating / decelerating / pushing device of the present invention drives all the rotational speeds of the rubber tire wheels that frictionally drive the transporter at the same rotational speed, and adjusts the rotational speed according to the traveling distance of the transporter. It is controlled to change and accelerate and decelerate. With such a configuration, even if the adjacent rubber tire wheels simultaneously contact the gripping machine, no slippage occurs between the rubber tire wheels and the gripping machine as seen in the conventional acceleration / deceleration pushing device.

Accordingly, the wear of the rubber tire wheels and the rope rig can be suppressed, and the frequency of maintenance of the device can be reduced. In addition, since the rubber tire wheels can drive the gripping machine without fail, the driving efficiency is increased, and smooth and reliable acceleration and deceleration transfer can be performed.
