DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage suction transport device for sequentially sucking and transporting refuse stored in a plurality of refuse storage containers to a refuse storage tank of a refuse suction truck. It relates to measures to smoothly suction and transport refuse from specific refuse storage containers that are difficult to handle.

[0002]

2. Description of the Related Art In general, in a garbage suction transport device for sucking and transporting garbage, a garbage suction vehicle is connected to a discharge port of a garbage storage container installed in an apartment house through a transport pipe, and a garbage storage container discharge port is provided. To release the waste storage container to a predetermined negative pressure value by the suction device of the garbage suction truck, and then introduce secondary air from the secondary air inlet into the negatively charged waste storage container. Thus, the refuse in the refuse storage container is suction-transported to the refuse storage tank of the refuse suction truck via the transport pipe.

[0003] When a plurality of refuse storage containers are installed, a garbage suction truck is connected to each refuse storage vehicle via a transport pipe branched at one end to a discharge port of each refuse storage container. By individually opening and closing the discharge ports of the storage containers by means of discharge valves, the refuse in each refuse storage container is sequentially suction-transported to the refuse storage tank of the refuse suction truck via the transport pipe. In such a garbage suction transport device, for example, as disclosed in Japanese Patent Publication No. 6-59922, a discharge valve of each garbage storage container and a secondary air introduction valve for opening and closing a secondary air inlet are controlled by a control device. Opening and closing operations are performed. The control by this control device will be specifically described.In a state where the discharge valve is opened in the order of suction and transport of each refuse storage container and both the refuse storage container and the refuse storage tank are set to a negative pressure, the secondary air The inlet valve is opened to introduce secondary air into the garbage storage container, and the suction pattern for sucking and transporting the garbage in the garbage storage container to the garbage storage tank is repeated several times, and the final suction pattern of the garbage storage container is repeated. Prior to closing the discharge valve, the discharge valve of the next-order garbage storage container is opened, and the final suction pattern in the garbage storage container and the first suction pattern in the next-order garbage storage container By partially overlapping the waste with each other, the transfer time of the suction transport between the waste storage containers in which the order of the suction transport is consecutive can be shortened, and the waste in the plurality of waste storage containers can be quickly suctioned and transported. Unishi to have.

[0004]

When a plurality of refuse storage containers are connected by a transport pipe, a difference occurs in a length of a branch portion of the transport pipe that branches toward an outlet of each of the refuse storage containers. There is. In such a case, only a small amount of refuse in the refuse storage container connected at the short branch portion enters the transport pipe due to the shortness of the divergence portion. Despite being transported by suction, a large amount of refuse in the refuse storage container connected at the long diverging section will enter the transport pipe along with the length of the diverging section, and the suction resistance at the diverging section will also be The dust may increase in proportion to end the final suction pattern of the refuse storage container, but the refuse is still in the middle of the suction transport and remains in the transport pipe. In this state,
Prior to closing the on-off valve such as the discharge valve in the final suction pattern of the refuse storage container, the on-off valve of the next-order refuse storage container opens and performs the next suction pattern on the garbage storage container. When the first suction pattern in the garbage storage container of the first order partially overlaps, as soon as the on-off valve of the garbage storage container of the next order opens, the negative pressure at the branch part of the garbage storage container decreases. However, the dirt stops at the branch portion, and the dirt is blocked.

[0005] Further, such a dust blockage also occurs when the lengths of the branch portions are substantially the same.
There are cases where garbage that exceeds the specified amount is stored in the garbage storage container, or heavy garbage such as kitchen garbage is stored.Of these multiple garbage storage containers, garbage storage that is likely to cause clogging It is also true that the identity of the container is known from experience. This is because the amount and composition of the garbage generated therefrom is determined to some extent by the lifestyle of the local residents, and the garbage storage containers used by residents who dump such garbage are naturally determined.

Therefore, by performing control to delay the opening operation timing of the on-off valve of the next refuse storage container and also delay the opening operation timing of the on-off valve of the preceding refuse storage container, It is conceivable to lengthen the final suction pattern. However, although such a control avoids dust blockage, it takes time to shift suction transport between the front and rear waste storage containers, and quickly sucks and transports waste in multiple waste storage containers. Can not.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to recognize a specific refuse storage container which is liable to blockage of refuse, and a preceding refuse storage container other than the specific refuse storage container. While the final suction pattern in the garbage container overlaps the first suction pattern in the next-order garbage storage container, the next-order garbage can be extended in a particular garbage storage container so that the final suction pattern in the garbage storage container is longer. By changing and controlling the opening / closing timing of the on-off valve between the storage container and the storage container, it is possible to quickly suck and transport the waste in the plurality of waste storage containers while avoiding the waste clogging.

[0008]

Means for Solving the Problems To achieve the above object, a solution taken by the invention according to claim 1 is to sequentially connect a refuse storage tank of a refuse suction truck to a plurality of refuse storage containers, By controlling the opening and closing valve provided in the opening and closing by the control device, to make the inside of the refuse storage container a negative pressure,
In this negative pressure state, the suction pattern in which secondary air is introduced into the refuse storage container and the refuse in the refuse storage container is suction-transported to the refuse storage tank is repeatedly performed, and the final suction cycle of one refuse storage container is performed. When a predetermined time has elapsed from the start, the on-off valve of the next-order refuse storage container is opened, and the final suction pattern in the refuse storage container and the first suction pattern in the next-order refuse storage container are compared. It is assumed that the waste suction and transport device is configured so that the parts overlap. And, the control device is provided with registration means for registering a specific refuse storage container which is likely to cause refuse obstruction in the middle of the transport pipe among the refuse storage containers, and the control device sucks refuse from the specific refuse storage container. In the case of transportation, the open / close valve of the next-order refuse storage container is not opened until the negative pressure value in the specific refuse storage container becomes substantially constant after the introduction of the secondary air in the final suction pattern. The on-off valve of the specific waste storage container is configured to be kept open.

The solution taken by the invention according to claim 2 is as follows.
The garbage storage tank of the garbage suction truck is sequentially connected to a plurality of garbage storage containers, and the on-off valve provided on the garbage storage container is controlled to open and close by a control device. The suction pattern in which secondary air is introduced into the refuse storage container in a state and the refuse in the refuse storage container is suction-transported to the refuse storage tank is repeatedly performed, and the refuse storage is performed in the final suction cycle of one refuse storage container. When the negative pressure value after the introduction of the secondary air in the container becomes smaller than the predetermined value, the on-off valve of the next-order garbage storage container is opened, and the final suction pattern in the garbage storage container and the next order It is assumed that a garbage suction transport device is configured to partially overlap the first suction pattern in the garbage storage container. And, the control device is provided with registration means for registering a specific refuse storage container which is likely to cause refuse obstruction in the middle of the transport pipe among the refuse storage containers, and the control device sucks refuse from the specific refuse storage container. In the case of transportation, the open / close valve of the next-order refuse storage container is not opened until the negative pressure value in the specific refuse storage container becomes substantially constant after the introduction of the secondary air in the final suction pattern. The on-off valve of the specific waste storage container is configured to be kept open.

According to the first and second aspects of the present invention, when suctioning and transporting refuse from a plurality of refuse storage containers, the on-off valve is opened in the order of suction transport of each refuse storage container, A suction pattern of introducing secondary air into the garbage storage container to suction and transport garbage is repeatedly performed a plurality of times, and the garbage of the next order prior to the closing operation of the on-off valve in the final suction pattern of the garbage storage container. The on-off valve of the storage container is opened, and the final suction pattern in the preceding waste storage container partially overlaps the first suction pattern in the next-ordered waste storage container. Therefore, the transfer time of the suction transport between the refuse storage containers in which the order of the suction transport is consecutive is shortened, and the refuse in each refuse storage container is quickly suctioned and transported.

In this case, the length of the branch portion of the transport pipe connecting the plurality of refuse storage containers is longer than others, or garbage far exceeding a specified amount is stored, or heavy garbage such as kitchen garbage. A specific refuse storage container that is likely to cause refuse blockage in the middle of a transport pipe in a normal suction pattern, such as when refuse is stored, is registered in the registration unit in advance. For this reason, when sucking and transporting garbage from a specific garbage storage container, in the final suction pattern of the specific garbage storage container, the next order of garbage until the negative pressure value becomes almost constant after secondary air introduction. The open / close valve of the storage container is not opened and the open / close valve of the specific waste storage container is held in an open state, so that the waste in the specific waste storage container is suction-transported to the waste storage tank without remaining in the transport pipe, The dust blockage in the middle of the transport pipe (branch) is reliably prevented.

The solution taken by the invention according to claim 3 is as follows.
In addition to the constituent elements of the invention according to claim 1 or claim 2, when suctioning and transporting refuse from a specific refuse storage container,
After the negative pressure value in the garbage storage container becomes substantially constant after the secondary air is introduced in the final suction pattern, the on-off valve of the garbage storage container of the next rank is opened, and after a predetermined time has elapsed, the specific garbage storage is performed. The opening and closing valve of the container is configured to be closed.

According to the third aspect of the present invention, the opening / closing valve of the garbage storage container of the next rank after the specific garbage storage container has a negative pressure value of secondary air introduction in the final suction pattern of the specific garbage storage container. Later, the opening operation is performed after it becomes substantially constant, and after a lapse of a predetermined time, the opening / closing valve of the specific garbage storage container is closed, so that the final suction pattern in the preceding garbage storage container and the next-order garbage storage container The first suction pattern overlaps with the first waste pattern for a predetermined time, and the transfer time of the suction transport to the next waste storage container connected to the specific waste storage container is shortened. Further, the overlap of the predetermined time ensures a sufficient time required for the waste in the specific waste storage container to enter the transport pipe from the branch part, and the waste in the branch part due to the waste in the specific waste storage container. Blockage is more reliably prevented.

[0014] The solution means taken by the invention according to claim 4 is as follows.
In addition to the constituent features of the invention according to any one of claims 1 to 3, each refuse storage container is provided with an input port for inputting refuse therein, and each input port is provided at each input port. Is provided with a dosing valve for opening and closing individually. The control device is configured to open the input valve prior to the introduction of the secondary air in the final suction pattern of each refuse storage container.

Thus, in the invention according to the fourth aspect, the charging valve is opened prior to the introduction of the secondary air in the final suction pattern of each refuse storage container, and the secondary air is removed from the residual refuse in the refuse storage container. The remaining waste in the waste storage container is suctioned and transported to the waste storage tank via the uptake transport pipe in the final suction pattern, and the waste in the waste storage tank is introduced. The suction transport efficiency is dramatically improved.

According to a fifth aspect of the present invention, in addition to the constituent features of the first aspect of the present invention, in addition to the constituent elements of the first aspect of the present invention, unique data of each garbage storage container is stored. The storage means to be provided is provided in the garbage storage. And
The configuration is such that the unique data of each refuse storage container from the storage means is registered in the registration means.

According to the fifth aspect of the present invention, the specific data of the specific waste storage container, that is, the length of the branch portion of the transport pipe connecting the plurality of waste storage containers is longer than other ones, or it is specified. If unique data such as garbage far exceeding the amount stored or heavy garbage such as kitchen garbage is stored in the storage means of the garbage storage in advance, identification that differs for each garbage storage It is not necessary to recognize the waste storage container in advance, and erroneous recognition of a specific waste storage container due to misunderstanding of an operator or the like is prevented. Moreover, if the unique data is stored in the storage means for each garbage storage site, the registration capacity (storage capacity) of the registration means can be reduced, and the storage means can be made compact.

The monitor 65 displays the state of suction of the refuse G by the suction device 23 and the number of the vessel B (for example, No. 15) that performs the suction and transportation of the refuse G. It is displayed. The number of the vessel B (vessel number Bm) displayed on the monitor 65 is subtracted and updated each time the transportation is completed by repeating the suction pattern in the vessel B twice, and the vessel number is smaller by one than the vessel B. The number of Bm is displayed.

Next, the opening and closing control of the input valve IV, the secondary air introduction valve NV, and the discharge valve EV by the control device 61 when sucking and transporting the refuse G from the plurality of vessels B to the refuse storage tank 24 will be described with reference to the time chart of FIG. Charts and FIGS. 4 to 8
A description will be given based on the flowchart of FIG.

In this case, the garbage suction truck C stops at the docking station D of the garbage storage X and stops.
The tip of the suction pipe 22 (the second flexible pipe 45) is connected to the docking station D by the turning operation of the tilting pipe 43, the tilting operation of the tilting pipe 43, the expanding and contracting operation of the telescopic pipe 44, and the like.

Is input from the storage means 62 to the registration means 63 (control device 61) of the garbage suction truck C. Further, detection signals from the detectors of the vessel B, the pressure sensor 37, and the like are also input to the control device 61.

First, step S in the flowchart of FIG.
In 1, the total number of vessels B in the garbage storage X is "15"
Is input to a counter CNT that decrements and updates each time suction is completed, and the monitor 65 displays a vessel number B that decrements and updates each time suction is completed for vessel B, similarly to the counter CNT.
Display the maximum value of m. In this case, the maximum value "No. 15" of the vessel number Bm is displayed on the monitor 65, but when continuing the previous suction and transportation of the garbage G, the continuation number of the previous suction and transportation at the garbage storage site X side. For example, when the previous suction / transport of the refuse G has ended at the vessel number B6, the monitoring is performed by assuming that the vessel number B5 at which the current suction / transport of the refuse G is started is the maximum value of the current vessel number. It is displayed at 65. That is, since the counter CNT is a variable for counting the number of unsucked vessels and the vessel number Bm is a variable for specifying the vessel B to be sucked, the values of both variables are not necessarily the same.

Next, in step S2, the inlet valve IVm of the vessel B of the first vessel number Bm to be suctioned and transported is opened, and the secondary air inlet valve NVm and the outlet valve EVm are closed. Then, in step S3, the specific vessel B input from the storage unit 62 to the registration unit 63
Is registered in the registration means 63, and in step S4, the variable m of the Bessel number Bm is initialized to "15". Then, in step S5, the discharge valve EVm of the vessel B is opened and the input valve IVm is closed, and then the process proceeds to step S6.

In this step S6, the blower 33 of the suction device 23 is operated to reduce the pressure of the waste storage tank 24 and the vessel B (vessel number Bm), that is, start suction. Then, in step S7, the pressure sensor 37
The pressure in the vessel B is reduced until the negative pressure value P of the blower 33 detected by the above becomes a first negative pressure value P1, which is a predetermined maximum negative pressure. When the negative pressure value P reaches the first negative pressure value P1, the process proceeds to step S8. move on. In this step S8, the secondary air introduction valve NVm of the vessel B is opened. Next, in step S9, the process waits until the negative pressure value P of the blower 33 decreases to the fourth negative pressure value P4.

Thereafter, as shown in FIG.
At 0, the secondary air introduction valve NVm of the vessel B is closed, and the measurement of the time T1 after the secondary air introduction valve NVm is closed is started by the timer 64. At step S11, the secondary air introduction valve NVm of the vessel B is closed. Time T1 after closing
Wait until elapses. Then, after the elapse of the time T1 by the timer 64, the process proceeds to step S12, the input valve IVm of the vessel B is opened, the timer 64 is reset, and the measurement of the time T5 after the opening of the input valve IVm is started. Then
In step S13, after opening the input valve IVm, the time T
The operation waits until 5 has elapsed, and proceeds to step S14 when the time T5 has elapsed. In step S14, the discharge valve EVm is opened, the timer 64 is reset, and the discharge valve EVm is released.
m Start measuring the time T2 after opening. Thereafter, in step S15, the process stands by until the time T2 elapses after the discharge valve EVm is opened. When the time T2 elapses, the process proceeds to step S16 to close the secondary air introduction valve NVm. Thereafter, in step S17, it is determined whether or not the vessel number Bm of the vessel B is the final vessel number B1 by using the variable "m = 1".
In the case of, the process proceeds to step S18.

As shown in FIG. 6, in this step S18, the unique data number "15" of the specific vessel B registered in the registration means 63 is compared with the variable "m" of the vessel number Bm, and the specific vessel B If the unique data number “15” is the same as the variable “m”, ie, YES, the process proceeds to step S19 shown in FIG. 7, and the negative pressure value P of the blower 33 is substantially constant below the fourth negative pressure value P4. Wait until Accordingly, when suctioning and transporting refuse from a specific vessel B, the vessel number Bm- in the next order until the negative pressure value P of the blower 33 becomes lower than the fourth negative pressure value P4 and becomes substantially constant.
1, the discharge valve EVm-1 of the specific vessel B is kept open without opening the discharge valve EVm-1 of the specific vessel B, and the preceding waste in the specific vessel B is passed through the waste transport pipe 13 to the refuse storage tank 24. In addition, it is possible to surely prevent dust from being clogged in the middle of the dust transport pipe 13 (branch portion 13a) due to dust in the specific vessel B.

Then, in step S20, the discharge valve E of the vessel B having the next vessel number Bm-1 in the next order.
Vm-1 is opened, the input valve IVm-1 is closed, and the measurement of the time T4 after the discharge valve EVm-1 is opened (the input valve IVm-1 is closed) is started. Thereafter, in step S21, the process waits until the time T4 elapses, and after the elapse of the time T4, the preceding vessel number Bm (specific vessel B1)
5) Close the discharge valve EVm of the vessel B. As a result, the final suction pattern at the vessel number B15 that becomes the specific vessel B and the vessel number B14 that becomes the next vessel B
Is overlapped with the first suction pattern by the time T4, and the transfer time of the suction transport to the next vessel B connected to the specific vessel B can be shortened. In addition, the time required for the debris in the specific vessel B to enter the refuse transport pipe 13 from the branch portion 13a is sufficiently ensured to prevent the debris in the specific vessel B from being blocked at the branch portion 13a. Is very advantageous.

Thereafter, in step S23, the variable m of the Bessel number Bm is subtracted by 1 to obtain a variable "m = m-1", and the process returns to step S6.

On the other hand, if the determination in step S18 is NO that the unique data number "15" of the specific vessel B does not match the variable "m", the preceding vessel number Bm
Of the vessel B is not a specific vessel B,
The process proceeds to step S24 shown in FIG. This step S24
Then, the discharge valve EVm-1 of the vessel B of the next vessel number Bm-1 is opened, the input valve IVm-1 is closed, and the discharge valve EVm-1 of the vessel B of the vessel number Bm-1 is opened.
T3 after opening the valve (closing the input valve IVm-1)
Start measuring. Thereafter, in step S25, the process waits until a time T3 shorter than the time T4 in step S21 elapses, and after the elapse of the time T3, closes the discharge valve EVm of the preceding vessel B. As a result, the last suction pattern in the vessel B having the vessel number m which is not the preceding specific vessel B and the first suction pattern in the vessel B having the next vessel number Bm-1 overlap by the time T3. . Specifically, vessel B of vessel number B14
And the first suction pattern in the vessel B of the vessel number B13 overlaps by the time T3, and the normal suction vessel B (the vessel number B14 and the vessel number B14) in which the order of the suction transportation is consecutive. The transfer time of the suction transport between the vessels B (number B13) is reduced, and the dust in each vessel B can be quickly transported by suction.

Thereafter, in step S27, the variable m of the Bessel number Bm is decremented by one to obtain a variable "m = m-1", and the process returns to step S6.

On the other hand, the determination at step S17 is that the vessel number Bm of the vessel B is the last vessel number Bm.
If the variable is “m = 1”, which is 1, the process proceeds to step S28 shown in FIG. 8, and the garbage storage tank without the garbage sucked in the final suction pattern of the last vessel B remains in the garbage transport pipe 13. Time T sufficient to be transported by suction into
6 Start the measurement. Thereafter, in step S29, the process waits until the time T6 elapses, and in step S30, after the time T6 elapses, the discharge valve EVm of the last vessel B is closed. Specifically, the last vessel B after the lapse of time T6
The discharge valve EV1 of the vessel number B1 is closed.

Then, in step S31, the operation of the blower 33 of the suction device 23 is stopped, and the suction transport of the dust is terminated.

Therefore, in the first embodiment, the opening valve IV of each vessel B is opened earlier by the time T5 than the opening operation of the secondary air introduction valve NV in the final suction pattern of each vessel B. As a result, the secondary air is introduced to the residual debris in the vessel B more quickly than the opening 5 on the most upstream side, so that the residual debris in the vessel B is transported uprooted in the final suction pattern. It is suction-transported to the refuse storage tank 24 via the pipe 13, and the efficiency of suction transfer of refuse into the refuse storage tank 24 can be dramatically improved.

Also, the unique data number of the specific vessel B in the refuse storage area X, that is, the length of the branch portion 13a of the refuse transport pipe 13 connecting the plurality of vessels B in the refuse storage area X may be longer than the others. Alternatively, a specific data number of a specific vessel B, such as garbage far exceeding a prescribed amount is stored, or heavy garbage such as kitchen garbage is stored in the storage means 62 of the garbage storage X in advance. If the suction pipe 22 is connected to the docking station D, it is input to the registration means 63, so that it is not necessary to recognize a specific vessel B different for each garbage storage in advance, and the operator may misunderstand. Erroneous recognition of a specific vessel B due to the above can be prevented. Moreover,
If the unique data is stored in the storage means 62 for each garbage storage X, the registration capacity (storage capacity) of the registration means 63 can be reduced, and the registration means 63 can be made more compact.

Next, a second embodiment of the present invention will be described with reference to FIGS.

In the second embodiment, the opening / closing control of the input valve IV, the discharge valve EV and the secondary air introduction valve NV in the suction pattern of each vessel B is performed based on the detection value (negative pressure value) of the pressure sensor 37. To do it.

That is, as shown in FIGS. 11 and 12, in step S9 of the flowchart of FIG. 4 of the first embodiment, the process waits until the negative pressure value P of the blower 33 decreases to the fourth negative pressure value P4. After that, step S4 in FIG.
Proceed to 1. In this step S41, the vessel number Bm
The secondary air introduction valve NVm of the vessel B is closed. Next, in step S42, the pressure in the vessel B is reduced until the negative pressure value P of the blower 33 by the pressure sensor 37 becomes a second negative pressure value P2 lower than the maximum first negative pressure value P1, and the negative pressure of the blower 33 is reduced. When the pressure value P reaches the second negative pressure value P2,
Proceed to step S43. In step S43, the input valve IVm of the vessel B is opened, and the discharge valve EVm is opened. Then, in step S44,
After waiting until the negative pressure value P of the blower 33 drops to a third negative pressure value P3 slightly higher than the fourth negative pressure value P4, the blower 3
When the negative pressure value P3 becomes the third negative pressure value P3, the process proceeds to step S45, and the secondary air introduction valve NV of the vessel B
Close m. Thereafter, in step S46, whether or not the vessel number Bm of the vessel B is the last vessel number is determined by the variable "m = 1", and the variable "m = 1"
If not, the process proceeds to step S47.

As shown in FIG. 13, this step S47
Then, the unique data number “15” of the specific vessel B is compared with the variable “m” of the vessel number Bm, and the specific vessel B
YE whose unique data number “15” is the same as the variable “m”
In the case of S, the process proceeds to step S48, and waits until the negative pressure value P of the blower 33 falls below the fourth negative pressure value P4 and becomes substantially constant. Then, if the determination in step S47 is NO, As in the case where the unique data number “15” of the vessel B of FIG.
Go to 9.

In step S49, the discharge valve EVm-1 of the vessel B having the next vessel number Bm-1 is opened, and at the same time, the input valve IVm-1 is closed.
Time T7 after opening m-1 (or input valve IVm-1
The measurement of the time T7) after closing is started. afterwards,
In step S50, the process waits until the time T7 elapses, and in step S51, after the time T7 elapses, the discharge valve EVm of the preceding vessel Bm is closed. Then, step S
At 52, the variable m of the Bessel number Bm is subtracted by 1 to obtain a variable "m = m-1", and the process returns to step S6.

As a result, the last suction pattern in the vessel B of the preceding vessel number m and the first suction pattern in the vessel B of the next vessel number Bm-1 overlap by the time T7. Specifically, the blower 33
After waiting until the negative pressure value P falls below the fourth negative pressure value P4 and becomes substantially constant, the final suction pattern at the vessel number B15 as the specific vessel B and the vessel number B14 at the next vessel B as the next vessel B Since the first suction pattern overlaps with the first suction pattern for a time T7, the time required for the debris in the specific vessel B to enter the debris transport pipe 13 from the branch portion 13a is sufficiently ensured, and the debris in the specific vessel B is reduced. The dust blockage at the branch portion 13a can be reliably prevented. Further, the final suction pattern in the vessel B having the vessel number B14, which is the normal vessel B, and the first suction pattern in the vessel B having the vessel number B13 are time T.
By overlapping by 7, the transfer time of the suction transport between the normal vessels B in which the order of the suction transport is consecutive is shortened, and the dust in each vessel B can be quickly transported by suction.

On the other hand, if the determination in step S46 is YES that the vessel number Bm is the last vessel number, the process proceeds to step S53, where the negative pressure value P
Is lower than the fourth negative pressure value P4, the discharge valve EVm of the last vessel B is closed in step S54. Specifically, the negative pressure value P of the blower 33 becomes the fourth negative pressure value P
After waiting until it becomes lower than 4, the discharge valve EV1 of the vessel number B1, which is the last vessel B, is closed.

Then, in step S55, the operation of the blower 33 of the suction device 23 is stopped, and the suction transport of the waste is ended.

Therefore, in the second embodiment, the input valve IV and the discharge valve EV in the suction pattern of each vessel B are used.
And the opening and closing operation of the secondary air introduction valve NV by the pressure sensor 37.
Based on the detected value (negative pressure value), the control can be simplified as compared with the case where the valves IV, EV, and NV are opened and closed by measuring time, and more accurate The valves IV, EV, NV can be opened and closed at the timing.

It should be noted that the present invention is not limited to the above embodiments, but includes various other modifications. For example, in the first embodiment, when starting the final suction pattern in each vessel B, the input valve IV
Is opened and the discharge valve EV is opened after a lapse of time T5. However, the opening and closing valves may be opened simultaneously. In the second embodiment, when starting the final suction pattern in each vessel B,
Although the input valve IV and the discharge valve EV are simultaneously opened, the input valve may be opened before the opening operation of the secondary air introduction valve.

Further, in each of the above embodiments, the refuse in each vessel B is suctioned and transported by the fixed initial suction pattern and the final suction pattern in the vessel B having a fixed capacity. When the dust in the vessel B is sucked and transported by the suction pattern described above, the suction pattern is appropriately changed, and the suction pattern is not limited to those in the above embodiments.

In the first embodiment, the overlap time T4 between the final suction pattern in the specific vessel B and the first suction pattern in the next vessel B is set to the final time in the normal vessel B. Suction pattern and next vessel B
Is set to be longer than the overlap time T3 with the first suction pattern in the above, but if it is sufficient to wait until the negative pressure value of the blower falls below the fourth negative pressure value and becomes almost constant, the specific vessel is used. The overlap time between the last suction pattern of the next vessel and the first suction pattern in the next vessel is set longer than the overlap time of the last suction pattern in the normal vessel and the first suction pattern in the next vessel. It is not necessary to perform these operations, and the two overlap times may be set to be the same.

In each of the above embodiments, the suction tube 2
2 is connected to the docking station D, the unique data of the vessel B from the storage means 62 is input to the registration means 63, but the unique data of the vessel of the garbage storage may be registered in the registration means in advance.
