In this case, the lifting force applied to the bucket according to the exhaust resistance at the actual exhaust port formed by the bucket C and the exhaust port +6 and the weight of the bucket C are in equilibrium, and the bucket C is stopped (floating) in the vertical pipe IO. The bucket C is configured to stop at a desired target floor by utilizing the principle that

A position detector such as a photoelectric sensor 70 is provided at each floor of the vertical pipe 10, and this position detector detects that the bucket C is at a position facing the input port 11a in the vertical pipe 10.

An air outlet 21 is provided below the first packet support device 15 of the vertical pipe IO. The air outlet 21 is connected to an air outlet 22a of the blower 22 by a pipe 23 having a valve 25, and one end of a pipe 26 having a valve 27 is connected to the air intake port 22b.

The other end 26a of this pipe 26 is made into an inlet for sucking air from outside the vertical pipe 1O. Furthermore, an air intake port 32 is provided above the first packet support device 15 in the lower part of the vertical pipe 10, and this air intake port 32 is branched from the blower 22 side of the pipe 26 beyond the valve 27. The valve 37 is connected to the pipe 36 which is connected to the pipe 36 via a valve 37. In addition, the valve 25 in the pipe 23 and the blower
One end of a pipe 28 having a valve 29 is connected to the blower 22, and the other end 28a of the pipe 28 is connected to the blower 22.
The vertical pipe 10 is provided with an exhaust port for discharging the air supplied from the vertical pipe 10 to the outside of the vertical pipe 10. In this way, there are 5 air outlets 21. Air intake port 32, blower 22, each piping 23.26.28
．． 36 and each valve 25, 27, 29, 37 constitute the air supply means 20, and by controlling the opening and closing of each valve, air is selectively sucked from the other end 26a of the piping 26 or the air intake port 32, The air can be selectively supplied to the other end 28a of the piping 28 or to the air outlet 21.

This air supply means 20 opens the valve 29.37 and sucks the air in the vertical pipe 10 from the air intake port 32, pipe 36, pipe 26, blower 22, pipe 23, pipe 28.
Ventilation state in which the inside of the vertical pipe 10 is ventilated by exhausting it to the outside through

This displacement control means 40 controls the displacement amount of the air compressed in the vertical pipe 10 by the bucket C when the bucket is lowered, and controls the lowering speed of the bucket C. In addition, although this exhaust amount control means 40 uses the air intake port 32 and a part of the piping 36 together as described above, it is not limited thereto and may be provided separately.

Each of the above-mentioned valves 25, 27, 29, 37, 39 is controlled to open and close by a control device such as a computer, so that the air supply path and the supply amount and exhaust amount control means 40 by the air supply means 20 described above can be used properly. . Among the valves, valve 25 and valve 39 are variable flow control valves whose flow rate can be adjusted by a control device, and in order to improve the sealing performance of these valves 25 and 39 and ensure airtightness in the vertical pipe IO. It is preferable to use a variable flow rate control valve and an on-off valve with high sealing performance in combination.

Further, a pressure measuring device P as a weight measuring means is provided at the lower end of the vertical pipe IO. This pressure measuring device P detects the pressure inside the vertical pipe 10 compressed by the bucket C in a sealed state after a predetermined time after the bucket C is dropped into the vertical pipe IO. The pressure measured by is output to the control device.

The garbage storage/unloading means provided near the discharge port 11b on the lowest floor of the building includes a reversing/feeding device 50 and a garbage storage/discharge device 60.
The 1-inversion loading device 50, which is equipped with the following, inverts the collection collector 13 conveyed from each floor and inputs the garbage contained in the collection collector 13 into the garbage storage and discharge device 60. Further, the garbage storage and discharge device 60 is
After storing the garbage input by the reversing input device 50, the garbage is discharged from the discharge port and transferred to the garbage collection vehicle 80.

Next, the operation of the bucket C transport system configured as described above will be explained.

Here, since the blower 22 takes time to start up from the start of operation until it reaches normal operation, it is normally operated all the time. The air in the vertical pipe 1O is sucked in from the air intake port 32 by opening the pipe 36. Piping 26
, the inside of the vertical pipe 10 is ventilated by discharging it to the outside through the blower 22, piping 23, and piping 28, and when the bucket C is descending inside the vertical pipe 10, the valve 37.25
When the air is opened, air in the vertical pipe IO is sucked in from the air intake port 32, passed through the pipe 36, pipe 26, blower 22, and pipe 23, and discharged from the air outlet 21 into the vertical pipe IO. The air is circulated by being sucked in from the vertical pipe 10, and an upward air current is generated between the air suita port 21 and the air intake port 32 in the vertical pipe IO.

First, a case will be described in which the bucket C is lowered from each floor to the lowest floor.

The bucket C is supported by the second bucket support device 14-L on the desired floor, and the gate 12 on this floor is opened to access the input port 1.
1a is opened and the collection collector 13 is carried into the bucket C. After that, the gate 12 is closed to make the inside of the vertical pipe 10 airtight, and the second packet support device 14 is operated to the lowering permission position to sink from inside the vertical pipe 10, so that the bucket C descends inside the vertical pipe IO. start. At this time, the air supply means 20 is operated by the valves 27 and 29 from the above-mentioned ventilation state by the control device.
The air is sucked in from the other end 26a of the piping 26 by opening only the piping 26, and passes through the blower 22, piping 23, and piping 28 to the piping 28.
It is in a so-called neutral state where it is discharged from the other end 28a.

Then, the bucket C descending inside the vertical pipe 1O gradually descends by letting the air in the vertical pipe 10 compressed by the bucket C gradually escape from the gap between the bucket C and the vertical pipe 1O.

Here, the steady-state falling velocity Vc of the bucket C can be expressed as: m: bucket mass ρ: air specific weight Cd: air resistance coefficient SP: vertical pipe stage area Sc: bucket pressure receiving area; The pressure Psl of the air inside the vertical pipe 10 can be determined by Sc. Therefore, with pressure measuring device P, vertical pipe 1
By detecting the pressure P31 within 0, mg can be obtained from equation (2), and by substituting this mg into equation (+), the steady falling velocity ■. can be found.

Therefore, when the bucket C is lowered, the pressure measuring device P measures the pressure inside the vertical pipe 10 a predetermined time after the bucket C starts to descend, and the control device measures the pressure inside the vertical pipe 10.
Based on the pressure P, 1 measured at -L, the steady-state falling velocity Vc of the bucket C is expressed by equation (1).

Calculate from (2). As a result, the control device
9 is opened to operate the displacement control means 40, the valve 39 is opened and closed to control the displacement so that the measured speed approximates the set speed, and the valve 37.25 is opened to operate the air supply means 20. from the neutral state to the landing speed control state.

That is, when the bucket C is lowered, the control bag [n controls the opening and closing of the valve 39 to operate the exhaust m control means 40, and the air in the vertical pipe 10 is transferred from the air intake port 32 to the pipe 36,
The air is discharged to the outside through the pipe 38, and by controlling the amount of air discharged, the descending speed of the bucket C is controlled to approximate the set speed. Specifically, if there is a difference between the bucket descent speed derived from the measured pressure and the set speed, the opening degree of the valve 39 is adjusted so that the bucket descent speed approaches the set speed, and the displacement is adjusted. control.

Such control of the descending speed of the bucket C is performed from the input floor until it passes through the air intake port 32 (just before landing).

Also, at this time, the air supply means 20 is in the landing speed control state, so that the air sucked in from the air intake port 32 is discharged from the other end 38a of the pipe 38 by the displacement control means 40. At the same time, the piping 36
, the air is supplied from the air outlet 21 via the piping 26, the blower 22, and the piping 23, is sucked in from the air intake 111 and the air intake 32, and circulates between the air outlet 21 and the air intake 32 in the vertical pipe 10. This creates an updraft. After the bucket C passes through the air intake port 32, that is, in the landing area from after this passing until it lands, the bucket C is moved by the updraft generated between the air outlet 21 and the air intake port 32. The descending speed is controlled to further slow down, and the packet slowly lands on the first packet support device 15.

In this case, the discharge amount from the air suita port 21 is adjusted by the valve 25, and this discharge amount only needs to generate an upward airflow to slow down the descending speed, and is compared to the discharge amount when raising the bucket C. There are only a few.

Note that in order to improve the responsiveness of the amount of air discharged by the valve 25, an auxiliary valve that can be finely adjusted may be provided alongside the valve 25.

After this, the air supply means 20 opens only the valve 29.37 to discharge the air in the vertical pipe 10 to the outside via the pipe 36, pipe 26, blower 22, pipe 23, and pipe 28, thereby creating a ventilation state. become. Then, open the gate 12 on the bottom floor and remove the collection collector 13 from the bucket C through the discharge port 11b.
The garbage stored in the collection collector 13 is thrown into the garbage storage and discharge device 60 using the reversing and feeding device 50.

Next, a case will be described in which the bucket C is raised from the lowest floor to a desired floor.

The garbage is transferred to the garbage storage and discharge device 60 by the reversing feeding device 50.
The empty collection collector 13 loaded into the first packet support device ? It is carried back into bucket C supported by ff115. After that, the gate 12 is closed, and the control device opens the exhaust valve 18 of the exhaust control means 19 of the desired floor to which the bucket C is to be transported, and the control device opens only the valves 25 and 27 to supply air. The means 20 is placed in the bucket-up conveying state.

As a result, air flows from the other end 26a of the pipe 26 to the pipe 26.
, blower 22, piping 23, air is sent to Suita outlet 21,
Air is supplied into the vertical pipe 10 from this air outlet 21 . By supplying air from the air outlet 21 in this way, the bucket C becomes a vertical pipe! Rise within 0. Here, a blower 22 having sufficient output to lift the bucket C is used.

When the bucket C reaches the desired floor where the exhaust valve 18 is opened, the bucket C
The product of the pressure Psm generated when the air supplied to raise the air is exhausted from the exhaust port 16 and the pressure receiving area Sc of the bucket C is balanced with the weight W of the bucket C, and the bucket C stops at this position. It turns out.

w = s c - p sx - (3)
Therefore, when the bucket C reaches the exhaust port 16 where the exhaust valve 18 is in the open state, the bucket C receives an air volume sufficient to maintain its position in its pressure receiving part, and part of the air volume that was contributing to the rise is transferred to the exhaust port 16. 16, and as a result, a lifting force that balances the bucket C is obtained. As a result, bucket C becomes stopped (floating).

Furthermore, by controlling the rotation speed of the blower 22 or the opening/closing of the valve 25, it is possible to adjust the volume of air supplied into the vertical pipe 10 via the air supply means 20 which is in the bucket upward conveyance state. This allows bucket C
Above y? It is also possible to stop the bucket C at a desired target floor while appropriately decelerating it by controlling the amount of air that contributes to .

The existence of the bucket C that has stopped at the desired floor is confirmed by the photoelectric sensor 70, and the second packet support device on the desired floor is thereby detected. ? I4 is activated to the bucket support position and supports bucket C. After this, gate +2 on this floor will be opened and collector 13 will be collected from bucket C.
is carried out from inside the vertical pipe IO to the desired floor.

When the bucket C is not transported within the vertical pipe IO, the valves 29 and 37 are opened to bring the air supply means 20 into a ventilation state.

In this way, the bucket C can be transported back and forth between each floor and the lowest floor.

Further, although a pressure measuring device is used as the weight detecting means, in addition to such indirect detection, the load acting on the bucket support device may be directly measured.

Furthermore, the discharge amount from the blower can also be controlled by controlling the valve 27 on the suction side.

(Effects of the Invention) As described above, the present invention enables the collection collector that stores the garbage collected on each floor to be transported back and forth between each floor and the collection site via the bucket, so that people and cargo can be transported by elevator. It does not obstruct the transportation of food and does not leave a putrid odor.

Furthermore, since the transport speed of the bucket can be adjusted arbitrarily, when applied to high-rise buildings, it is possible to transport the bucket up and down in a short time, reducing overall working time and improving work efficiency. Can be done.
