Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is directed to a rope that circulates between stops at both ends, a carrier equipped with a gripping machine that grips and releases the rope, and each stop. Forwarding rails that are installed in the field to transport the transporter from the arrival side to the departure side, a speed reducing mechanism that is disposed on the arrival side of the transporting rails to decelerate the transporter, and a transporter that is disposed on the starting side of the transport rail. And an accelerating mechanism for accelerating the decelerating mechanism and the accelerating mechanism, and an endless carrier interval regulating conveyor that is provided between the decelerating mechanism and the accelerating mechanism and provided with a plurality of carrier engaging portions at predetermined intervals, together with the circulation of the rope. The present invention relates to a constant-interval operation device for an automatic circulation cableway, in which a carrier is moved for transportation.

<Prior Art> Conventionally, as a constant interval operation device for an automatic circulation type cableway of this type, for example, a speed reducing mechanism and an accelerating mechanism are configured with a large number of tires as disclosed in Japanese Patent Publication No. Sho 64-10382, and these tires are used as a carrier. The carrier is decelerated or accelerated by the frictional force generated by abutting against it, and the speed of the tire located at the most downstream side of the deceleration mechanism is made approximately equal to the moving speed of the carrier interval regulating conveyor, and each carrier engaging part is freely retractable. It consists of a flat eight-shaped ratchet, and the decelerated transporter is at the leading position and the ratchet catches up from the rear and engages, keeping a certain number of transporters constant during the forward rail. There is a system in which each carrier is regulated so as to depart after a lapse of a certain time by sequentially transferring to the acceleration mechanism, and in addition, a carrier following the departure carrier is arranged in a waiting state for departure.

<Problems to be solved by the invention> However, in such a conventional constant-distance operation device for an automatic circulation type cableway, since the carrier is decelerated or accelerated by frictional force with a large number of tires, for example, fluctuations in the number of passengers Due to the uneven weight of each carrier due to, the degree of wear and dryness of the acceleration / deceleration plate of each carrier that comes into contact with the tire, and the unevenness of the surface condition of each acceleration / deceleration plate due to the difference in the icing / snow condition, If the departed carrier circulates through the other stop and repeats acceleration and deceleration until it returns to the other stop, the intervals between the carriers become uneven.

Due to the density of the carrier intervals, for example, when the carrier that has arrived and passed through the last tire of the deceleration mechanism is delayed in time from the originally scheduled passage timing, the carrier engaging portion of the carrier interval regulating conveyor. Passes through the engagement position first without engaging with the delayed carrier, the delayed carrier stops on the spot after passing through the last tire of the speed reduction mechanism, and the stopped carrier is stopped. If the carrying device engaging portion catches up with and is engaged with the carrying device, a large load is applied to the carrying device, the carrying device engaging portion, and the carrying device interval regulating conveyor, and there is a problem that durability of these is deteriorated.

Furthermore, if the carrier that arrives next to the stopped carrier passes the last tire of the speed reduction mechanism earlier than the originally scheduled passage timing, in this case, the next carrier is stopped. Since it should be engaged with the next transporter engagement part of the transporter engagement part that should have been engaged with the transporter, the transporter is transferred by one transporter engagement part and the next transporter is transferred to the stopped transporter. There is a risk of collision.

Therefore, in order to prevent the collision of the carrier, the carrier is delayed in advance by considering the delay of the carrier and controlling the timing at which the carrier passes the last tire of the reduction mechanism to be earlier within the allowable range. Also, it is possible to prevent the carrier locking part of the carrier interval control conveyor from passing first, and additionally provide an engagement adjustment section for the carrier engaging part to catch up with the carrier that has passed the last tire of the reduction mechanism. To be

However, in this case, if the engagement adjustment section is lengthened so that the carrier locking portion can be reliably engaged even if the carrier is significantly delayed, the total length of the carrier interval regulating conveyor becomes longer by that amount. There is also a problem that the whole becomes large.

In view of such conventional circumstances, the present invention engages with the carrier engaging portion of the carrier restricting conveyor while continuing low-speed transfer without stopping each carrier regardless of variation in arrival timing of each carrier caused by unevenness of carrier intervals. The purpose is to transfer at high speed to the acceleration mechanism.

<Means for Solving the Problem> The technical means taken by the present invention to solve the above-mentioned problems are as follows: in the same direction as the moving direction of the conveyor for regulating the distance between the conveyors, below or above the conveyor for regulating the distance between the conveyors. The endless conveyor for pushing the carrier that moves at a slower speed is wound,
A plurality of engaging protrusions are provided on the conveyor for pushing the carrying device at intervals shorter than the arrangement interval of the carrying device engaging portions of the conveyor for regulating the carrying device interval, and these engaging projections are engaged with the carrying device in the anti-travel direction. It is characterized in that it is supported so as to be depressed when a force is applied in the traveling direction while being projected.

<Effect> According to the above technical means, the present invention makes it possible for the carrier decelerated by the speed reduction mechanism to immediately engage the engaging protrusion of the conveyor for pushing the carrier, which causes the carrier to be transported at a low speed. , The transporter engaging portion of the transporter interval regulating conveyor that moves at high speed catches up with and engages with the transporter that is moving at low speed, and then the transporter is transported at high speed, and the transporter that is moving at high speed precedes the low speed. Each time the catching protrusions that are moving are caught up and hit, these catching protrusions are retracted and sequentially passed.

The tires (E ₁ ) that run are controlled to be the slowest.

Next, the operation of such a fixed-distance operation device for an automatic circulation type cableway will be described.

First, the gripping machine (not shown) of the carrier (F) is the cord (B ₂ ).
When the vehicle is released into the forwarding rail (C), the tires (D ₁ ) ... constituting the speed reduction mechanism (D) are sequentially brought into contact with each other to be decelerated.

When the carrier (F) passes through the speed reduction mechanism (D),
The engaging projection (2a) of the conveyor (2) for pushing the carrying device immediately engages with the suspended portion (F ₁ ) of the carrying device (F) to push it at a low speed.

The carrying device engaging portion (1c) that moves at high speed during this pushing catches up with and engages with the preceding carrying device (F) suspension part (F ₁ ), and thereafter, the carrying device (F) is carried by the carrying device interval regulating conveyor (1). Is sent at high speed.

Along with this, each time the suspension section (F ₁ ) of the carrier (F) catches up with the preceding engaging projections (2a) ...
₃ ) Rotate in the traveling direction to pass, and then the transporter (F) is handed over to the acceleration mechanism (E) to accelerate and then the gripping machine grips the cord (B ₂ ). Depart at regular intervals.

After that, the above-described operation is repeated every time each carrier (F) enters the forwarding rail (C).

In the embodiment shown above, the conveyor for pushing the carrier (2) is installed below the conveyor (1) for regulating the interval of the carrier, but the present invention is not limited to this, and it may be installed above the conveyor. The traction belts (1a) (2c) of both conveyors (1) and (2) are each constituted by a chain, but the present invention is not limited to this, and steel ropes or belts may be used. Each of the abutting portions (2a) ... Is composed of a ratchet, but this is not a limitation and any other structure having a similar function may be used.

<Effect of Device> Since the device of the present invention has the above-described configuration, it has the following advantages.

A carrier that moves at a low speed to the carrier that has been decelerated by the speed reduction mechanism immediately engages with the engaging projection of the conveyor for pushing the carrier to move the carrier at a low speed, and moves at a high speed with respect to the carrier that is moving at a low speed. The carrier engaging portion of the interval regulating conveyor catches up with and engages, and then the carrier is transferred at high speed,
Each time the carrier moving at high speed catches up with and hits the preceding engaging protrusion at low speed, these engaging protrusions are retracted and sequentially passed, so that the arrival timing of each carrier caused by the density of carrier intervals becomes small. Irrespective of the variation, it can be transferred at high speed to the acceleration mechanism by engaging with the carrier engaging portion of the carrier restricting conveyor while transferring at low speed without stopping each carrier.

Therefore, when the arriving carrier is delayed, the carrier does not stop because the carrier engaging portion of the carrier interval regulating conveyor passes first to stop the carrier. The engaging portion can be smoothly engaged with each other, a heavy load is not applied to the carrying device, the carrying device engaging portion, and the carrying device interval regulating conveyor, and the durability of these can be improved.

Further, the conveyor for regulating the interval between the carry units can be shortened and the entire apparatus can be made compact as compared with a case where an engagement adjustment section for catching up the carry unit engaging portion is separately provided on the delayed carry unit.

Also, in consideration of the delay of the carrier beforehand, the carrier is controlled so that the timing at which it passes through the last tire of the speed reduction mechanism is accelerated within the allowable range, and even if the carrier is delayed, the carrier lock of the conveyor for regulating the carrier interval is carried out. If the parts do not pass through first, the collision of the carrier can be completely prevented and it is safe.
