Description

TECHNICAL FIELD The present invention relates to a dust container transporting device for transporting a dust capsule type dust container packed with a synthetic resin sheet in a vertical transport pipe.

[Conventional technology]

Conventionally, in general, in a high-rise building, the garbage discharged from households such as condominiums is packed in a garbage bag such as a plastic bag used when shopping at a supermarket, and the garbage bag ( The plastic bags were put into a vertical transportation pipe (dust chute) having a diameter of about 500 mm from this charging port and dropped along the vertical transportation pipe.

However, as the condominiums increase in height, the falling speed of dust bags such as vinyl bags filled with dust gradually increases due to gravity fall, and the dust bags collide with the wall surface of the vertical transportation pipe while falling, and It may collide with the bottom of the top surface and tear. If the dust bag is torn in this manner, the inside of the vertical transport pipe is contaminated and becomes a source of foul odors and cockroaches.

In order to solve these problems, waste is put in a certain waste container (capsule), and the gap between the outer diameter of this capsule and the inner diameter of the vertical transport pipe (dust chute) is made into a certain small area. Or measuring the pressure in the vertical transport pipe to control the balance between gravity and air resistance,
By forming an air rising area in the vertical transport pipe and controlling the rising air flow velocity between the air rising areas in accordance with the falling velocity of the dust container detected above the air rising region, the capsule (dust container ) Of which the drop speed is made constant so that it can be softly landed on the ground floor, and further, a vertical transport pipe equipped with a reduction pipe smaller than the upper diameter near the lower end has been developed ( For example, Japanese Patent Sho 60
-286, JP-A-63-252804, JP-A-63-160904).

[Problems to be Solved by the Invention]

However, in the above-mentioned conventional example, since it is necessary to use a fixed container (capsule) having a fixed shape, it takes time and effort to collect and wash a plastic container having a large capacity, and a small capacity that a housewife at home can carry. With disposable containers (capsules) such as paper bags, not only is it troublesome to refill garbage, but generally 700 to 800 garbage containers are used per household at one year, so the cost for this garbage container is also considerable. Thus, the current situation has been the hindrance to the spread of these.

Also, as the diameter of the vertical transportation pipe (dust chute) becomes larger, the weight of the waste container (capsule) also becomes heavier and it is necessary to increase the air resistance to be balanced against this. It is necessary to minimize the gap between the waste container and the outer diameter. However, the solid waste container has a shape of an inverted truncated cone so that it can be usually stacked in order to reduce the storage area, so it is difficult to reduce the area of the gap in the longitudinal direction of the container. In addition, in order to balance the air resistance and the capsule weight to lower the constant velocity, it is necessary to reduce the clearance between the upper surface of the capsule and the wall surface of the dust chute, so it is necessary to set a very strict clearance dimension. Will be needed.

Furthermore, if the gap between the waste container and the vertical transport pipe is reduced in this way, the dust container may come into contact with the peripheral wall of the vertical transport pipe and be destroyed during this drop.

Also, if a decompression pipe with a small diameter is placed only near the lower side of the vertical transport pipe to slow down the garbage container and make a soft landing, the descent speed at a large diameter becomes relatively high. , The garbage container (capsule) may be destroyed when it rushes into the decompression pipe, and the garbage is scattered.
The inside of the dust chute might be contaminated.

Furthermore, in order to slow down the garbage container and make it land softly, in the case where the blower blows air from the lower part of the vertical transport pipe to decelerate the garbage container, the equipment cost is not only considerably high. However, there was a problem that it also caused a problem in terms of maintenance.

In view of the above, the present invention can surely reduce the falling speed of the dust container that drops the vertical transport pipe in accordance with the weight of the falling dust container, and has a relatively simple configuration, which requires a high equipment cost. The purpose is to provide a product that does not end up.

[Means for Solving the Problems]

In order to achieve the above object, a waste container transportation device for a high-rise building according to the present invention is provided with a vertical transportation pipe that guides a waste container filled with dust that is thrown in from each floor of a building downward, and is connected to this vertical transportation pipe. In a waste container transportation device for a high-rise building having a waste loading inlet provided on a required floor, the waste container is made of a soft cylindrical body having an outer diameter slightly smaller than the inner diameter of the vertical transportation pipe, A clip device for closing the upper part of the waste container filled with the waste thrown in through the input port, and an auxiliary cylinder having a shape having the same diameter as the inner diameter of the vertical transport pipe and at the receiving position of the waste container after sealing. And a middle container forming a part of the vertical transportation pipe are integrally connected to each other, and a moving device for the waste container in which the positions of the auxiliary cylinder and the intermediate container can be exchanged are provided, and the lower end of the vertical transportation pipe is provided. With a bottom lid that can be opened and closed freely An openable air discharge device and a detection means for detecting the pressure in the vertical transport pipe are provided above the bottom cover, and the detection signal of this detection means controls the opening / closing amount of the air discharge device to drop the dust container. It is designed to control the speed.

[Work]

According to the present invention configured as described above, the waste container is made of a flexible poly sheet or the like, and this kind of waste container is formed in a cylindrical shape unlike the conventional solid waste container having a truncated cone shape. Since it is dropped while maintaining its shape, the gap area occupied by the vertical transport pipe inner wall and the outside of the waste container can be kept constant over the longitudinal direction of the waste container,
The air resistance passing through this narrow passage becomes large, so that the clearance area between the vertical transportation pipe and the vertical transportation pipe is regulated so strictly, and a speed reducer that decelerates the dust container falling in the vertical transportation pipe by an ascending air current is used. The waste container can be surely decelerated without providing.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

1 to 12 show the first embodiment, and as shown in FIG. 2, a vertical transport pipe (dust chute) 1 is provided for dropping and transporting dust through each floor of a high-rise building. And, on each floor, there is a cylindrical body 2 with a garbage inlet 3 connected integrally.
Are installed parallel to the vertical transport pipe 1.

This vertical transport pipe 1 is a waste 4 that is thrown in through the above-mentioned inlet 3.
It is for dropping a garbage container (capsule) 5 (see FIG. 1) in which the inside is packed, and at its lower end, a bottom lid that can project so as to traverse the vertical transport pipe 1 via a cylinder 6. 7 is arranged, and by this bottom lid 7, the vertical transport pipe 1
Are configured to be sealed.

Then, the dust that has fallen and transported in the vertical transport pipe 1 is stored in the dust storage tank 8, and when the dust storage tank 8 is full, it is carried by the dust collection truck 9.

An air discharge device 10 is provided above the bottom cover 7 as shown in FIG. That is, as shown in the figure, the vertical transport pipe 1 is provided with an air exhaust port 1a, and the exhaust port 1a is provided with three different types of valves 11a, 11b, 11c, and an exhaust port opened at the atmospheric emission port 12 is provided. A pipe 13 is connected, and the valves 11a, 11b and 11c are appropriately opened and closed by a signal from a pressure detector 14 which detects the pressure in the vertical transportation pipe 1.

Thus, the drop velocity when the dust container 5 falls in the vertical transport pipe 1 is detected by detecting the pressure in the vertical transport pipe 1 with the pressure detector 14, and this drop velocity is slower than a predetermined speed. In this case, the valves 11a, 11b, 11c are appropriately opened and closed to control the discharge amount of air, and thereby the descent rate of the waste container 1 is set to a predetermined rate.

That is, the vertical transport pipe 1 is hermetically sealed, the inside is made airtight, the dust container 5 is dropped, and the air pressure Pd when the velocity of the dust container 5 becomes constant is W, the weight of the dust container 1 and the dust container 1 Let Ac be the cross-sectional area of It can be expressed as.

Here, the compressed air on the lower surface of the waste container 5 escapes upward through the space between the waste container 5 and the vertical transport pipe 1, and at this time, air resistance is generated in the waste container 5. This air resistance is
Pressure loss due to abrupt contraction caused by air suddenly entering a narrow gap, and flow resistance to allow air to pass through the narrow gap at high speed (10 to 12 times the speed of the garbage container 5) (compared to the other two). This resistance is the largest and the influence on Cd is the largest),
It is the sum of the sudden expansion pressure loss for suddenly coming out from the narrow gap to the wide upper vertical transport pipe 1.

By the way, this air resistance (drag) R can be expressed as follows.

Where γ is the specific weight of air, v is the dropping speed of the waste container, and A is
d: cross-sectional area of vertical transportation pipe, Cd: drag coefficient (this drag coefficient has a constant value depending on the shape of the waste container).

Since this air resistance R is equal to the air pressure Pd, Becomes

From this, the falling speed v of the waste container 5 is proportional to the square root of the weight W of the waste container 5. (If the dust chute diameter and capsule container diameter are fixed Therefore, V is uniquely determined by W. ) The above equation is for a state in which the inside of the vertical transport pipe 1 is sealed. On the other hand, if the exhaust amount of air from the air exhaust port 1a is V ₀ , Becomes

Thus, it can be seen that the falling speed of the dust container 5 is increased by (V ₀ / Ac) by exhausting air from the air exhaust port 1a.

Therefore, when the weight of the dust container 5 is light and the falling speed is slower than the predetermined speed, the exhaust amount V ₀ from the air discharge port 1a is increased, and conversely, when the weight is heavy and the falling speed is fast, this exhaust amount V By performing control to reduce ₀ , the falling speed of the dust container 5 can be made constant.

As shown in FIG. 4, the dust inlet 3 is closed by a lid body 15, and the lid body 15 has
An arc-shaped guide plate 16 is attached, and by this, the volume of dust to be thrown in is restricted to a predetermined amount or less.

Although not shown, a counter for counting the number of times the dust is thrown in is disposed near the dust throwing port.

As shown in FIG. 1, below the dust input port 3, a cylindrical dust receiver 17 is arranged inside the tubular body 2,

As a result, when it is detected that the poly sheet 18 in the dust receiver 17 is filled with the dust 4 by counting the number of times the dust is thrown, the dust receiver 17 is moved to the poly sheet 18 via the dust receiver moving cylinder. By moving the upper and lower cylinders 21 to a position below the upper and lower cylinders 21 and then operating the upper and lower cylinders 21, the poly sheet 18 with the dust 4 is passed through the automatic clip device 23 and guided into the auxiliary cylinder 22. It is configured to compress the refuse 4.

The automatic clipping device 23 is for clipping and cutting the poly sheet 18 at a predetermined position, and the garbage container 5 is configured by being clipped and cut by the automatic clipping device 23. That is, when the cassette 19 is mounted, the lower end 18a is manually clipped as described above, and thereafter, the polyclip 18 is cut and clipped by the automatic clipping device 23 to form the dust container 5. It

The outer diameter of the poly sheet 18 (waste container 5) is slightly smaller than the inner shape of the vertical transport pipe 1.

Further, an intermediate cylinder 24 having the same shape and forming a part of the vertical transport pipe 1 is integrally connected to the auxiliary cylinder 22 by a connecting rod 25, and is connected to a cylinder moving cylinder 26. The auxiliary cylinder 22 and the intermediate cylinder 24 are integrally moved by the operation of the cylinder 26.

The intermediate cylinder 24 forms a part of the vertical transport pipe 1 when dust is thrown in, that is, the vertical transport pipe 1 located above and the vertical transport pipe 1 located below communicate with each other through the intermediate pipe 24, and a cylinder moving cylinder is provided. When the 26 is activated and it is advanced, the auxiliary cylinder 22
Is a part of the vertical transport pipe 1, that is, the vertical transport pipe 1 located above and the vertical transport pipe 1 located below

As shown in FIG. 6, the poly sheet 18 is closed inward so as to be narrowed down. The order of this operation is such that the upper narrowing member 28 is closed first, and after a short delay, the lower narrowing member 28 is closed.

A clip arm 32 is provided slightly below the narrowing member 28 located above and slightly above the narrowing member 28 located below, and each lip arm 32 has a pin 33.
It is rotatably attached to the frame body 30 via.

A clip portion 34 for clipping the poly sheet 18 is connected to the tip end of the clip arm 32, and is rotated by an air cylinder (not shown). With the sheet narrowed down, place the poly sheet 18 at two points A and B.
Clip in place. This point B is a clip point for forming a lower end closure of the next waste container 5, and a point A is a clip point for upper closure of the waste container 5 clipped vertically.

Further, a cutter arm 35 having a cutter 36 at the tip thereof is arranged substantially at the center of the clip arm 32, and the cutter arm 36 is used to cut the poly sheet at a point C intermediate between points A and B.
18 is cut to separate the upper and lower closed waste containers 5 from the poly sheet 18. The cutter arm 35 is also swung around the pin 37 by the operation of the air cylinder in the same manner as described above.

In this way, the waste container 5 which is vertically closed from the poly sheet 18 and is filled with dust is formed. As described above, the poly sheet 18 is first squeezed by the squeezing member 28 located above, and thereafter, By squeezing with the squeezing member 28 located below, air can be enclosed in the inside of the dust container 5.

That is, as shown in FIG. 11 (b), the poly sheet 18 is first squeezed by the squeezing member 28 located above, and the poly sheet 18 is squeezed by the squeezing member 28 located below with a slight delay so that both the narrowing points Poly sheet 18 sandwiched between
The air inside is trapped inside the waste container 5, and the size of the waste container 5 can be made substantially constant.

The shape of the poly sheet 18 is determined so that the area occupied by the inside of the vertical transportation pipe 1 and the waste container 5 is about 8 to 10% of the cross-sectional area of the vertical transportation pipe 1.

Next, the operation of the above embodiment will be described with reference to FIGS.

First, as shown in FIG. 9, the dust 4 charged from the charging port 3 is packed in the poly sheet 18 located in the dust receiver 17.
At this time, the lower end 18a of the poly sheet 18 is previously clipped when the cassette 19 is mounted, or is clipped thereafter by the automatic clipping device 23. And
The fact that the inside of the poly sheet 18 is filled with dust 4 is detected by counting the number of dusts thrown in.

Next, as shown in FIG. 10, the dust receiver moving cylinder is operated to move the dust receiver 17 to a position below the upper and lower cylinders 21, and then the upper and lower cylinders 21 are operated to remove the poly sheet 18. While being automatically pulled out from the cassette 19, the poly sheet 18 with the dust 4 is passed through the inside of the automatic clipping device 23 and is positioned inside the auxiliary cylinder 22.

In this state, as shown in FIG. 11, the automatic clipping device 23

Then, it is clipped by the clip portion 34 and further cut by the cutter 36 at a point C, whereby the waste container 5 which is closed up and down and has the waste 4 packed therein is separated from the poly sheet 18.

Thereafter, as shown in FIG. 12, the cylinder moving cylinder 26 is actuated to move the auxiliary cylinder 22 so as to form a part of the vertical transport pipe 1, and thereby the waste container located in the auxiliary cylinder 22. 5 is dropped in the vertical pipe transport pipe 1. At this time, the amount of air exhausted from the air exhaust port 1a is controlled as described above to control the drop speed to be constant. On the other hand, the dust receiver moving cylinder is operated in reverse to the above to show the dust receiver 5 at the position below the input port 3.

Then, the cylinder moving cylinder 26 is reversely operated to return the auxiliary cylinder 22 to the position immediately below the upper and lower cylinders 21, and the intermediate cylinder 24 forms a part of the vertical transport pipe 1. To do.

FIG. 13 and FIG. 14 show another embodiment, and the difference between the above embodiments is as follows.

That is, the upper and lower cylinders 21 are arranged directly above the dust receiver 5 which is fixed to the dust input port 3 so as to be immovably fixed, and the automatic clip device 23 and the auxiliary cylinder 22 are sequentially arranged linearly below the dust receiver 5. The upper and lower cylinders 21 are operated to move the dust packed in the poly sheet 18 into the auxiliary cylinder 22 while passing through the automatic clip device 23 without moving the. The intermediate cylinder 24 constituting the above is inclined toward the auxiliary cylinder 22 so as to become narrower in width.

By configuring the intermediate cylinder 24 in this way,
By fitting 24 into the vertical transport pipe 1 tightly, airtightness can be improved, and odor and soundproofing effects can be improved.

〔The invention's effect〕

Since the present invention is configured as described above, the waste container is made of a flexible poly sheet or the like, and this kind of waste container is formed into a cylindrical shape with air enclosed therein, and has an auxiliary cylinder and an intermediate cylinder. Since it is dropped into the vertical transport pipe while maintaining a constant cylindrical shape by the moving device of the waste container, the clearance area occupied by the inner wall of the vertical transport pipe and the outside of the waste container is constant along the longitudinal direction of the waste container. Since the area can be maintained, the air resistance passing through this narrow passage becomes large, and the deceleration effect becomes larger than that of the conventional solid waste container having a shape like an inverted truncated cone. Therefore, the clearance area between the vertical transportation pipe and the vertical transportation pipe is not so strictly regulated, and a speed reducer for decelerating the dust container falling in the vertical transportation pipe by an ascending air current is not provided, thus increasing the facility cost. The garbage container can be surely decelerated without being lost.

Moreover, it is not only necessary to collect the capsules as in the case of a specially-designed capsule with a large capacity, but also the garbage thrower puts the garbage into a normal vinyl shopping bag etc. and puts it in from the garbage throwing port. Just good. Further, there is an effect that it is possible to eliminate the need for refilling dust such as a special disposable container of a small container, and to eliminate the cost of purchasing this.
