BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic circulation cableway such as a ski lift constructed so that a carrier released from a rope is pushed by a pushing device at the foothill side terminal and the mountaintop side terminal. The present invention relates to a carrier pushing system installed in a terminal of

[0002]

2. Description of the Related Art Generally, an automatic circulation type cableway of this type generally comprises a rope that circulates between a terminal at the foot of the mountain and a terminal at the summit of the mountain, and a large number of ropes suspended and supported by the rope through a gripping machine. It comprises a carry device and a carry device pushing system provided at each terminal.

Thus, each carrier pushing system includes a deceleration pushing device, an in-place pushing device, and an accelerating pushing device. In the carrying device pushing system provided at one terminal, each pushing device is , Is configured as follows.

That is, the decelerating and pushing device decelerates and transports the carry device discharged from the rope from the entrance region to the entrance-side delivery region, and includes a large number of push-driving wheels that can frictionally engage with the carry device. It is configured to be arranged in parallel in the transport direction of the carrier, and to rotate and drive each of the push-and-roll wheels arranged in the entrance-side delivery area in the transport direction of the carrier at a peripheral speed lower than the boarding / alighting speed.
That is, in the entrance-side delivery area, the carrier is configured to be transferred at a speed lower than the boarding / alighting speed. Further, the in-place pushing device receives the carrier from the deceleration pushing device in the entrance-side delivery area, and transfers the boarding / alighting area connected to the entrance-side delivery area at a constant boarding / alighting speed.
A large number of pushing claws that can be engaged with the carrier, at regular intervals,
It is a chain conveyor configured to travel at a boarding / alighting speed in the transport direction of the carrier. Further, the accelerating and pushing device receives the carrier transferred from the boarding / unloading area to the exit-side passing area by the on-board pushing apparatus, transfers it from the exit-side passing area to the exit area while accelerating the boarding / alighting speed to the rope speed, and exits the exit. It is to be delivered to the rope in the area, and is generally constituted by a push-and-roll wheel group similar to the decelerating push device.

By the way, the decelerating and pushing device is constructed so as to transfer the carrier at a speed lower than the boarding / alighting speed, that is, the traveling speed of the pushing pawl in the entrance-side delivery region, as described above. The carrier to which is transferred relatively waits for the pushing claw that advances in the entrance-side delivery area. Therefore, in the entrance-side delivery area, each of the pushing claws that advance to the boarding / alighting area can reliably receive the carrying device, and the carrying device transfer in the boarding / alighting area is performed at regular intervals. If the transport speed of the transport device in the entrance-side delivery area by the deceleration pushing device is equal to or higher than the traveling speed of the pushing claw, there is a possibility that there is a pushing claw that does not receive the transport device from the deceleration pushing device or a transport device that cannot be received by the pushing claw. Therefore, there is a possibility that the carrier may not be transferred at a constant interval in the boarding / alighting area.

On the other hand, when the pushing claw of the in-field pushing device receives the carrying device which is transported at a speed lower than the traveling speed thereof, when the pushing claw is engaged with the carrying device, the carrying device is moved and pushed by the pushing claw. Since there is a speed difference between the transfer of wheels and the transfer of the transfer device, the deceleration pushing device and the in-field transfer device are overloaded due to the engagement of the pushing claw with the transfer device, and a large impact is generated on the transfer device to smoothly transfer the transfer device. Can't do.

In the prior art, therefore, in order to solve such a problem, each of the push-and-push wheels and the drive shafts arranged in the entrance-side delivery area is moved relative to the push-and-push wheels with respect to the drive shaft. By connecting via a one-way clutch that allows idling in the transport direction, it is devised so that when the pushing claws engage the transport device, the push-and-roll wheels frictionally engaged with the transport device run idle. There is. That is, when the pushing claw engages with the carry device, the pushing / rolling wheel idles following the transfer of the carry device by the pushing claw,
In other words, the push roller is rotated at a higher speed than the drive speed of the drive shaft, so that the transport of the transport device from the push roller to the transport claw is smoothly performed, and the decelerating transport device and the in-field transport device are overloaded and the transport device is transported. The occurrence of impact is prevented as much as possible.

[0008]

However, in the transporter pushing system (hereinafter, referred to as "conventional system") devised in this way, there is a fear that the transporter may escape in the entrance side delivery area, and the deceleration pushing device. However, there was a problem that the delivery of the carrier to the on-site pushing device was not smoothly performed.

In other words, since the push-and-roll wheels arranged in the inlet-side delivery area can idle in the transport direction, the wind force in the transport direction acts on the transport device being transported by the push-and-roll wheels. There is a risk that the push-wheel assembly may slip and the carrier may run away. In particular, when the carrier has a hood with a large wind-receiving area, the wind pressure acting on the carrier also becomes large, so that even in a situation where the wind is not so strong, there is a high possibility that the carrier will escape due to the wind pressure. Of course, at the mountaintop side terminal, which is easily affected by the wind, this risk is extremely significant.

The present invention has been made in view of the above-mentioned points, and the delivery of the carrier from the deceleration pushing device to the in-place pushing device causes an overload to the deceleration pushing device and the in-place pushing device and an impact to the carrying device. An object of the present invention is to provide a carrier-pushing system for an automatic circulation cableway, which can be smoothly carried out without any trouble and can favorably prevent escape of the carrier due to the influence of wind.

[0011]

According to the present invention, there is provided a decelerating and pushing device for decelerating and transporting a carrier unloaded from a cord from an entrance area of a terminal to an entrance side delivery area, and a carrier in an entrance side delivery area. The deceleration-pushing device receives from the deceleration-pushing device and transports the entry / exit area connected to the entrance-side delivery area at a constant loading / unloading speed. Are arranged side by side in the transporting direction of the transporter and are configured to drive each of the push-and-roll wheels arranged in the entrance-side delivery area to rotate in the transporting direction of the transporter at a peripheral speed lower than the boarding / alighting speed. In the system, in order to achieve the above-mentioned object, in particular, each of the push-feed rolling wheels and the drive shaft thereof arranged in the inlet-side delivery area is set so that the circumferential velocity of the push-feed rolling wheels is higher than the circumferential velocity given by the drive shaft. Become At this time, it is connected with a first pad receiver which is connected to the input side rotary system from the drive shaft to the input part of the one-way clutch so as not to be relatively rotatable, while being connected through the one-way clutch that functions to idle the push-wheel. The friction pad is pinched between the output side rotary system from the output part of the directional clutch to the second pad receiver which is provided so as not to rotate relative to the output side rotation system, so that the push roller has a predetermined rotational resistance force in the idling state. It is suggested to be configured so as to give. Thus, in such a carrier-pushing system, it is preferable to provide a friction adjusting mechanism for adjusting the degree of pinching of the friction pad by both pad receivers.

[0012]

In the entrance-side delivery area, the carrier is delivered from the deceleration pushing device to the in-place pushing device. At this time, the transport speed of the carry roller by the push roller of the deceleration push device, that is, the peripheral speed of the push roller provided by the drive shaft is lower than the transport speed of the transport tool by the in-field push device, that is, the boarding / alighting speed. But,
Since the push-and-roll wheel is connected to the drive shaft via the one-way clutch, when the transport of the carrying device at the boarding / unloading speed by the on-site push-start device is started, the push-and-roll wheel will idle. Therefore, the transfer from the deceleration pushing device to the in-place pushing device is smoothly performed, and the overloading of the deceleration pushing device and the in-place pushing device at the time of delivery and the occurrence of impact on the carrier are prevented as much as possible.

Further, the push-rolling wheel arranged in the inlet-side delivery area is allowed to idle in the transporting direction as described above, but in the idling state, the friction pad provides a predetermined rotational resistance force. Is given. Therefore, during transfer of the carrier by the push roller,
Even when wind pressure acts on the carrier, idling of the push-and-roll wheel that causes the carrier to escape is suppressed as much as possible by the rotation resistance force. That is, the escape of the carrier is prevented as much as possible.

The rotation resistance force is determined by the frictional force between the first and second pad receivers and the friction pad sandwiched between the pad receivers. Therefore,
By setting the degree of pinching of the friction pad by both pad receivers to be appropriate, it is possible to effectively achieve both smooth delivery of the transporter from the push-and-roll roller to the in-site pusher and prevention of escape of the transporter.

That is, the second wheel 19 ₂ drives the carrier 4 to the drive shaft 20.
_The forward rotation is performed so that the sheet is transferred backward at a speed corresponding to the driving speed of ₂ , that is, the delivery speed V ₂ . And
The traveling speed of the carrier 4 to the rear exceeds the delivery speed V _2, and the second wheel 19 ₂ frictionally engaged with the friction plate 18 transfers the delivery speed V _2.
When the normal rotation occurs at a peripheral speed exceeding ₂ , the rotation of the outer ring 22b becomes faster, so torque is not transmitted from the inner ring 22a to the outer ring 22b via the sprag 22d (Fig. 6 (B)). 2), the second wheel 19 ₂ idles in the forward rotation direction. In other words, the presence of the second wheel 19 ₂ that frictionally engages the friction plate 18 of the gripping machine 13 does not hinder the movement of the carrier at a speed exceeding the delivery speed V ₂ .

Further, the first side of the input side rotation system from the drive shaft 20 ₂ to the inner ring 22a which is the input portion of the one-way clutch 22 is provided.

It is fitted so that it cannot rotate relative to. The main body portion 25a has an appropriate gap with the clutch inner ring 22a,
It is abutted against the step portion 20a of the drive shaft 20 ₂ and is prevented from moving to the left.

The collar portion 26b is fixed to the wheel 19a of the second wheel 19 ₂ with the collar portion 26b facing the collar portion 25b of the first pad receiver 25 in the right direction.

As shown in FIG. 5, the friction pad 27 is an annular body made of a resin mold or the like used for a brake pad, and is a collar portion 25 of both pad receivers 25 and 26.
It is inserted between b and 26b.

As shown in FIG. 5, the friction adjusting mechanism 28 has an appropriate number of disc springs 29 inserted into and held by the left end portion of the drive shaft 20 ₂ protruding from the clutch inner ring 22a, and the left end portion of the drive shaft 20 _2. A pair of adjusting nuts 30, 30 screwed into the protruding screw portion 20b, and a spring receiver 31 arranged between the disc spring 29 and the adjusting nut 30 to be inserted and held in the screw portion 20b are provided.

The disc springs 29 directly press the clutch inner ring 22a to the left as shown in FIG. The biasing force of the disc springs 29, that is, the degree of pinching of the friction pad 27 between the pad receivers 25 and 26 can be arbitrarily adjusted by the adjusting nuts 30 and 30. Therefore, by appropriately adjusting the clamping degree of the friction pad 27 with the adjusting nuts 30, 30, when the second rolling wheel 19 ₂ idles as described above, a desired rotation resistance force is exerted on the second rolling wheel 19 _2. Can be given. In the configuration of this embodiment, as shown in FIG. 5, the second roller wheel 19 ₂ is displaced in the axial direction in accordance with the adjustment of the pinching degree, but the displacement is caused by the second roller wheel 19 ₂ gripping. The friction plate 18 of the machine 13 can be sufficiently and satisfactorily frictionally engaged, and since it is extremely small, there is no problem in terms of the function of the decelerating and pushing device 6. The friction pad 27 is used for the second wheel 19

_In the idling state of the clutch disengagement in which the torque is not transmitted to ₂ , the friction resistance between the pad receivers 25 and 26 and the friction pad 27 sandwiched between the pad receivers 25 and 26 causes a rotational resistance force to the second wheel 19 _2. To work. Therefore, this rotation resistance force prevents the second wheel 19 ₂ from slipping and prevents the carry device 4 from running away. This rotational resistance is
It is set so as to prevent escape of the carrier 4 as much as possible within a range in which the delivery to the pushing claw 55a is smoothly performed. This setting can be arbitrarily performed by adjusting the degree of clamping of the friction pad 27 by the pad receivers 25, 26 by the adjusting nuts 30, 30, that is, the biasing force of the disc springs 29.

Therefore, by appropriately setting the rotational resistance force by the friction pad 27 in accordance with the shape of the transporter 4 (whether or not it is provided with a hood having a large wind receiving area, etc.) and the operating conditions of the cableway. , While smoothly carrying the carrier from the second wheel 19 ₂ to the pushing claw 55a,
The escape of the carrier 4 can be effectively prevented.

The present invention is not limited to the above-mentioned embodiments, but can be appropriately improved and changed without departing from the basic principle of the present invention.

That is, the pad receivers 25 and 26 are connected to the inner ring 22 which is the input portion of the one-way clutch 22 from the drive shaft 20 _2.
The input side rotation system up to a and the output side rotation system from the outer ring 22b, which is the output part of the one-way clutch 22, to the second rolling wheel 19 ₂ may be provided so as not to be rotatable relative to each other, and their arrangement and configuration are arbitrary. . For example, if the first pad receiver 25 is
It is also possible to configure the second pad receiver 26 on the inner peripheral portion of the outer ring 22b in addition to the outer peripheral portion of a so that the friction pad 27 is interposed between the inner and outer rings 22a and 22b in a pinching manner.

It is also possible to directly press the outer ring 22a by the adjusting nuts 30, 30. Of course, the configuration of the one-way clutch 22 is also arbitrary, and in addition to the sprag type clutch, an inner ring cam roller type clutch or the like can be used.

Further, the constitution of each pushing device such as the deceleration pushing device 6 is also arbitrary. For example, in the above embodiment, the second transfer wheels 19 ₂ ...
_Although it is driven at ₂ , the second rollers 19 ₂ ... Arranged in the front half of the entrance-side transfer area B may be configured to be driven while gradually decelerating rather than at a constant speed. .

[0042]

As can be easily understood from the above description, according to the transporter pushing system of the present invention, the transfer of the transporter from the decelerating pushing device to the in-place pushing device is performed by the decelerating pushing device and the in-place pushing device as in the conventional system. It can be carried out smoothly without overloading the device or impacting the carrier, and can prevent the carrier from traveling due to wind pressure as much as possible, thus realizing extremely safe and good cableway operation. .
