結してなるダストシュート装置が知られている。``Conventional technology'' Today, garbage collection and delivery in buildings such as high-rise apartment complexes is
Various problems arise in terms of hygiene, transportation labor, aesthetics, etc. Namely, there are problems such as spoilage and odor caused by garbage storage, the complexity of transporting the garbage to the garbage collection site, and problems in terms of the time taken to discharge the garbage, which is limited by the garbage collection mortar. Therefore, various techniques have been proposed in the past that do not solve these problems, and generally, vertical pipes connected to each floor of a building are connected to garbage collection points near the ground level. Dust chute devices that are connected are known.

ゴミを輸送するといった手段か提供されている。However, although this has increased the degree of freedom in garbage removal work, there remains the problem that foul odors are generated from the garbage that adheres to the collection area or inside the vertical pipes.
In order to solve this problem, the garbage is stored in a sealed capsule-shaped garbage container, and the lower end of the vertical tube is connected to an air transport tube extending horizontally, and the garbage is transported together with this garbage container. There are ways to do this.

落下速度を減速、制御する必要がある。"Problems to be Solved by the Invention" By the way, in the conventional means, when the garbage container discharged from the building falls down the vertical pipe, there is a risk that it will collide with the air transport pipe and be damaged. In other words, under conditions where the diameters of the vertical pipe and the garbage container are relatively close, and therefore the increase in the falling speed is offset by the air resistance acting on the garbage container, the falling speed of the garbage container will be equal to the total falling speed of the garbage container. It is known that scale can be described as a linear function for weight. Therefore, when the garbage container is at its maximum weight, that is, when the garbage container is full of garbage, the falling speed of the garbage container is reduced so that the falling speed I'J is within the collision damage limit speed. need to be controlled.

点を抱えていた。One way to control the falling speed of a garbage container is to increase the air resistance acting on the garbage container, such as by narrowing the clearance (gap) between the garbage container and the vertical pipe. There are ways to slow down and control the speed. However, in this method, as mentioned above, the garbage container is designed to prevent damage when it is at its maximum weight, so when it is lightweight, the falling speed of the garbage container slows down, reducing the efficiency of garbage discharge. , had seven problems.

している。The present invention has been made in view of the above-mentioned circumstances, and it reduces the falling speed of garbage containers that keep garbage in an airtight state before reaching the lower collection site, and also allows the garbage containers to be vertically dropped regardless of the total weight of the individual garbage containers. The object of the present invention is to provide a method and device for controlling the falling speed of a garbage container, which can control the falling speed within a pipe to a desired speed.
「問題点を解決するための手段」
本発明者等は、前記問題点に鑑みて鋭意研究した結果、
次に述べるような知見を得るに至った。"Means for Solving the Problems" As a result of intensive research in view of the above problems, the present inventors have found that:
We have come to the following findings.

Ｓに変化がない範囲で維持される。That is, immediately after a garbage container is placed into a vertical pipe, it falls at a constant speed Uf that depends on its total weight W, as described above, and this falling speed Uf is determined by the clearance area between the vertical pipe and the garbage container (hereinafter referred to as This is called the relief area )Δ
S is maintained within a range where there is no change.

If it is less than 10, the pressure inside the vertical pipe due to the fall of the garbage container P
The increase in s by 1 is described as a linear function with respect to the total weight W of this garbage container.

落下速度Ｕｆは垂直管内圧力Ｐｓの関数ともなる。Ps=f(W) (2) Therefore, if the condition of equation (2) is satisfied, the falling speed Uf of the garbage container also becomes a function of the vertical pipe pressure Ps.

-(3) Furthermore, when the relief area ΔS fluctuates at a rate of change ΔS', the vertical pipe internal pressure Ps temporarily fluctuates to Ps', and this Ps' is related by the following equation.

(4) Therefore, if the pressure Ps in the vertical pipe while the garbage container is falling is measured by a pressure measuring means, it becomes possible to grasp the final current MW of this garbage container, and if the total weight W of the garbage container can be grasped, The relationship between the falling speed Uf and the relief area ΔS is uniquely determined. Usually, this relationship will be a proportional relationship. Thereby, by changing the relief area ΔS by some means, it becomes possible to control the falling speed Uf of the garbage container.

速度を制御することが可能となる。"Function" In the present invention, the total weight of the garbage container can be determined by measuring the pressure inside the vertical tube using a pressure measuring means installed in the vertical tube, and this allows the proportional relationship between the falling speed of the garbage container and the relief area to be determined. It becomes possible to make a unique decision. By opening and closing the air discharge section attached to the vertical pipe, this relief area can be increased or decreased, thereby making it possible to control the falling speed of the garbage container.

Furthermore, by appropriately opening and closing the air discharge section attached to the deceleration pipe, sudden changes in the relief area between the vertical pipe and the deceleration pipe can be alleviated, thereby reducing the sudden pressure change acting on the garbage container. It is possible to avoid this.

In this state, the garbage container 5 into which a predetermined amount of garbage has been thrown is thrown into the vertical pipe 1 from the slot 4 on each floor, and falls downward in the vertical pipe 1.

整するのである。By knowing the total weight of the garbage container 5, the proportional relationship between the falling speed of the garbage container 5 and the above-mentioned relief area (i.e., the clearance area between the vertical pipe I and the garbage container 5) can be uniquely determined. The relief area may be increased or decreased so that the falling speed of the garbage container 5 falls within a certain range. Specifically, when the total weight of the garbage container 5 is light, the relief area is increased to accelerate the falling speed, and when the total weight of the garbage container 5 is heavy, the relief area is decreased and the falling F speed is reduced. let The relief area is increased or decreased by opening and closing the relief valve 13. In other words, as the garbage container 5 falls, this garbage container 5
As the air below is compressed, the pressure inside the vertical pipe 1 increases, so this compressed air is transferred to the relief pipe 9.
By letting the air escape from the exhaust port 8 through the air, the relief area is adjusted.

面積が急激に減少しないようにする必要が生じる。Next, the garbage container 5 falls down the vertical pipe 1, and the step 6
When entering the deceleration pipe 7 via the deceleration pipe 7, since the deceleration pipe 7 is formed to have a smaller diameter than the vertical pipe 1, its falling speed is reduced. However, as shown in equation (4) above, as the relief area decreases due to entry into the deceleration pipe 7, the pressure inside the deceleration pipe 7 temporarily increases, and this is a factor that causes damage to the garbage container 5. There is a risk that Therefore, when the garbage container 5 enters the deceleration pipe 7, it is necessary to prevent the relief area from decreasing rapidly.

By letting the air escape to the outside or to the vertical pipe 1 through the relief pipe 9 and the exhaust port 8, the sudden decrease in the relief area is alleviated. In particular, it is preferable to gradually reduce the relief area toward the bottom of the deceleration pipe 7 to gradually decelerate the garbage container 5.
It is desirable to adjust the buffer tube 10a1 so that the lower the buffer tube 10a1 is, the smaller the amount of air flowing through it. Based on the conditions explained above, relief valve 1

うる、等の優れた効果が得られる。"Effects of the Invention" As explained in detail above, according to the present invention, by measuring the pressure inside the vertical pipe with the pressure measuring means provided in the vertical pipe, the total weight of the garbage container can be ascertained. It is possible to uniquely determine the proportional relationship between the falling speed of the container and the relief area, and by opening and closing the air exhaust section attached to the vertical pipe, this relief area can be increased or decreased, thereby reducing the amount of garbage. It becomes possible to control the falling speed of the container. In addition, the speed reducer installed at the lower end of the vertical pipe is formed to have a smaller diameter than the vertical pipe, so when a garbage container enters the speed reducer, the falling speed of the garbage container is automatically reduced, and By opening and closing the attached air exhaust section as appropriate, it is possible to alleviate sudden changes in the relief area between the vertical pipe and the deceleration pipe, thereby avoiding sudden pressure changes acting on the garbage container. becomes. Therefore, according to the present invention, the garbage container can be dropped at a desired speed regardless of the total weight of the garbage container, and the falling speed of the garbage container can be slowed down just before reaching the lower collection point, and , no unnecessary shock is given to the garbage container during deceleration. Therefore, the efficiency of garbage discharge is improved, there is no risk of damage to the garbage container, and it is possible to prevent the garbage stored inside the garbage container from being scattered outside. This not only eliminates the backflow of strange odors generated by scattered garbage into the living space, but also provides excellent effects such as providing a comfortable working environment for the workers performing the disposal work. It will be done.
