Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage suction transportation device for sucking and transporting garbage stored in a garbage storage container to a garbage storage tank of a garbage suction vehicle, and more particularly, to a garbage suction vehicle for garbage stored by the suction transportation. The present invention relates to measures for maintaining a compressed state without breaking down in a refuse storage tank due to vibrations during traveling movement of the garbage.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Application Laid-Open No. 6-286804.
In the garbage suction transport device for sucking and transporting garbage, a garbage suction truck is connected to a garbage storage container installed in an apartment house or the like via a garbage transport pipe, and a discharge gate for the garbage storage container is disclosed. Is opened and the garbage storage container is vacuumed to a predetermined negative pressure value by a suction device of the garbage suction vehicle, and then secondary air is introduced into the vacuumed garbage storage container, whereby the garbage storage container The refuse is suction-transported through the refuse transport pipe to a refuse storage tank of a refuse suction truck.

In addition, when the refuse is transported to a certain extent into the refuse storage tank by the refuse suction transport described above, the refuse is compressed by a compression plate provided in the refuse storage tank to compress the refuse with the rear wall. By performing the operation, the refuse is efficiently stored in the refuse storage tank.

[0004]

By the way, in the above-mentioned conventional waste suction / transport device, the compression plate is normally positioned at the frontmost suction / transport position which enables the suction / transport of the waste. And the reason why the compression plate moves rearward is that
Either at the time of refuse discharge in which the rear wall is opened to discharge refuse in the refuse storage tank, or at the time of refuse compression operation. For this reason, even when the garbage suction truck travels, the compression plate is positioned at the suction transport position. In this case, even if the refuse is compressed by the compression plate before the garbage suction truck travels, the traveling vibration is reduced. Even if the garbage collapses forward and moves to the vicinity of the connection port of the garbage transport pipe, etc., in this state, even if the garbage arrives at the next garbage storage site and the garbage is suction-transported from the garbage storage container of the garbage storage site, Since the garbage sucked and transported accumulates on the garbage that has collapsed forward, there is a problem that the garbage is likely to be blocked near the connection port of the garbage transport pipe. Also, even if the garbage does not collapse due to running vibration, etc.,
While traveling, the garbage is released from the compressed state,
There is also a problem that the storage space in the refuse storage tank is reduced by the springback of the refuse itself, and the refuse storage efficiency is reduced.

[0005] The present invention has been made in view of such a point, and an object of the present invention is to make it possible to compress refuse stored in a refuse storage tank by a compression plate as much as possible except during suction transportation. In addition, it is possible to prevent the waste from being blocked near the connection port of the waste transport pipe, and to improve the storage efficiency of the waste.

[0006]

Means for Solving the Problems To achieve the above object, a solution taken by the invention according to claim 1 is to connect a waste storage tank of a waste suction truck to a waste storage container provided in a waste storage area. The garbage stored in the garbage storage container is sucked and transported to the garbage storage tank, and the garbage sucked and transported to the garbage storage tank is compressed by a compression plate provided in the garbage storage tank. Assume a waste suction transport device. Detecting means for detecting the suction transport operation when the garbage is sucked and transported by the garbage suction truck; and garbage collecting the compression plate based on a detection signal from the detection means when the suction transport operation is released. While the suction and transport operation is controlled to move from the suction and transport position capable of suction and transport to the compression position for holding the waste in the waste storage tank in a compressed state, while the suction and transport operation is being performed, based on the detection signal from the detection means, And a control device for controlling the compression plate to move from the compression position to the suction transport position.

[0007] The solution taken by the invention of claim 2 is as follows.
The same applies to the refuse suction / transport device described in claim 1. And a detecting means for detecting a movement operation of the garbage suction vehicle when moving the garbage suction vehicle from the garbage storage,
A compression position for holding the refuse in the refuse storage tank in a compressed state from a suction / transport position where the refuse can be suction-transported to the refuse based on the detection signal from the detection means when the refuse suction truck is moving. Control to move
And a control device that controls the compression plate to move from the compression position to the suction transport position based on the detection signal from the detection means when the moving operation of the refuse suction truck is released. .

Thus, according to the first and second aspects of the present invention, when the suction transport operation for sucking and transporting garbage by the garbage suction truck is canceled, or when the garbage suction truck is moved from the garbage storage site, When the moving operation of the garbage suction truck is performed, each operation is detected by the detecting means, and based on the detection signal, the control device moves the compression plate from the suction transportation position to the compression position to compress the garbage in the garbage storage tank. Since it is controlled to maintain the state, the waste compressed by the compression plate before traveling of the garbage suction vehicle does not collapse forward due to traveling vibration and move to the vicinity of the connection port of the garbage transport pipe. .
Therefore, when the garbage arrives at the next garbage storage site and the garbage is sucked and transported from the garbage storage container of the garbage storage site, the sucked and transported garbage is suctioned and transported in front of the garbage compressed and held by the compression plate. Accordingly, dust clogging near the connection port of the transport pipe is reliably prevented. Further, since the refuse is kept in a compressed state during the traveling movement, the springback of the refuse itself due to traveling vibration or the like is also restricted, and a storage space in the refuse storage tank can be secured.

On the other hand, if the detection signal from the detection means indicates that the suction operation is performed or the moving operation of the garbage suction truck is released, the compression plate is moved from the compression position to the suction transportation position. Thus, since the garbage can be sucked and transported, the garbage can be smoothly sucked and transported from the garbage storage container of the garbage storage when it arrives at the next garbage storage.

[0010] The solution taken by the invention of claim 3 is as follows.
The control of the compression plate by the control means of the invention according to claim 1 or 2 is specified. In particular,
When the amount of refuse stored in the refuse storage tank is small enough not to require compression by the compression plate, the control device does not control the compression plate.

According to the third aspect of the present invention, when the amount of refuse stored in the refuse storage tank is such that compression and holding is not required, the compression plate is not moved from the compression position to the suction transport position. Are located at the suction transport position, the garbage suction truck travels and arrives at the next garbage storage site, and then it is necessary to move the compression plate from the compression position to the suction transport position in preparation for the garbage suction transport. In addition, the waiting time required for moving the compression plate is reduced, and the suction and transport of the refuse is performed quickly.

According to a fourth aspect of the present invention, there is provided a control device for controlling a compression plate by the control device according to any one of the first to third aspects of the present invention. . Specifically, at the rear end of the refuse storage tank, an openable door that opens rearward when discharging refuse from the refuse storage tank is provided. Then, when the rear wall is opened in a state where the dust is held in a compressed state by the compression plate, the control device is configured to control the compression plate to move to the suction transport position side where the compression force of the dust is reduced. Things.

According to the fourth aspect of the present invention, when the rear wall is opened, the compression plate moves to the suction / transport position side, and the compressive force of the debris due to the compression and holding with the rear wall is reduced. The load acting on the locking portion of the rear wall due to the compressive force of the dust is reduced.

I have. The number of the vessel B displayed on the monitor 62, to be precise, the number of the vessel number Bm to be described later is subtracted and updated each time the transportation is completed by repeatedly performing a predetermined suction pattern according to the size of the vessel B, The number of the vessel number Bm which is one smaller than the vessel B is displayed.

Next, the garbage suction vehicle V
The control by the control device 61 from the suction transportation of the refuse G to the refuse storage tank 24 to the compression and discharge of the refuse G will be described with reference to the flowcharts of FIGS.

First, in the flowchart of FIG. 3, when the control device 61 of the garbage suction vehicle V is turned on, in step S1, the distal end of the suction pipe 22 (second flexible pipe 45) and the docking station D are connected. ON from docking sensor DS to determine connection with coupling 21
The presence or absence of signal detection is determined.

Now, for example, in a certain waste storage area X, the suction and transport of the waste G from the vessel B is completed, the suction pipe 22 is removed from the coupling 21 of the docking station D, and the connection between the two 21 and 22 is released. In this case, since the ON signal from the docking sensor DS is not detected, it is determined that the garbage suction vehicle V is to be moved from the garbage storage X, and the compression holding flag PF is determined in step S2. This compression holding flag PF indicates that the hydraulic pressure of the telescopic cylinder 52 is set to a predetermined value P2 (in a state where the waste G is stored to some extent in the waste storage tank 24) in a waste compression operation routine in an automatic suction routine described later.
This flag is set to 1 when it becomes equal to or more than the hydraulic pressure limit value P1). In this case, since the compression plate 51 is immediately after the suction transportation of the refuse G from the vessel B is completed,
It is located at the front suction transport position.

If the determination in step S2 is YES, that is, PF = 1, the operation of pushing the compression plate 51 backward (compression operation) is started in step S3, and the operation proceeds to step S4.
Until the hydraulic pressure of the telescopic cylinder 52 reaches or exceeds the hydraulic pressure limit value P1 (for example, 80% of the maximum hydraulic pressure value), or the compression time of the compression plate 51 is detected in step S5.
Until 1 reaches the compression position, the compression plate 51 is compressed.

When either of the conditions of step S4 or step S5 is satisfied, the process proceeds to step S6,
The compression plate 51 is stopped. Thereby, when moving the garbage suction vehicle V from the garbage storage X, the garbage G in the garbage storage tank 24 is kept in a compressed state by moving the compression plate 51 from the suction transport position to the compression position, and the garbage is sucked. The dust G compressed by the compression plate 51 before traveling of the vehicle V is broken forward by traveling vibration or the like so as not to move to the vicinity of the inlet 40 of the suction pipe 22. Therefore, the garbage G that arrives at the next garbage storage and is sucked and transported from the garbage storage container of the garbage storage is compressed and held by the compression plate 51.
In the vicinity of the inlet 40 of the suction pipe 22 to reliably prevent dust from being blocked. Further, since the refuse G is kept in a compressed state during the traveling movement, the garbage G itself is also prevented from springback due to traveling vibration or the like, so that a storage space in the refuse storage tank 24 is secured and the refuse G is stored. Efficiency can be improved.

When the operation of holding the compression plate 51 by the compression holding flag PF in steps S2 to S6 is completed, the determination in step S2 becomes PF.
In the case of = 0, that is, as in the state where the compression plate 51 is still positioned at the suction / transport position, the processing shifts to the processing after step S7.

In steps S7 to S36, the open / close door switch OS, the storage switch XS, the retreat switch TS, the direct suction switch KS, the tilt switch LS, the telescopic switch SS, and the turning switch C of the operation panel 30 are used.
S, the confirmation process and the operation process of the compression plate switch AS are sequentially performed.

Specifically, in step S7, the open / close door switch OS is moved to the open position (the position indicated by the two-dot chain line in FIG. 9).
It is determined whether or not the operation has been performed at step S8.
Then, the compression holding flag PF is determined again. If the determination in step S8 is YES, that is, PF = 1, in step S9, it is determined that the dust G is held in a compressed state by the compression plate 51, and the compression plate 51 is moved forward (on the suction transport position side). To a predetermined time. As a result, the garbage suction vehicle V is operated from the garbage storage X and arrives at a garbage disposal site (not shown) which is the final destination, and then the door 46 is operated by operating the door switch OS to the open position. In the case of opening, the compression plate 51 moves forward for a predetermined time toward the suction / transport position side, and the compressive force of the dust G due to the compression holding between the door 46 and the opening / closing door 46 is reduced. The load applied by the compression force of the refuse G can be effectively reduced.

Then, in step S10, the opening / closing cylinder 48 is contracted and the opening / closing door 4 is closed, as in the case where the determination of the compression holding flag PF in step S8 is "0".
After releasing 6, the compression plate 51 is moved rearward to the discharge position, and the refuse G stored in the refuse storage tank 24 is discharged to the rear of the refuse suction vehicle V. At this time, step S7
In the discharge routine of step S10, the variables required for the series compression calculation of the automatic suction routine, which will be described later, are initialized to predetermined values, such as the accumulated capacity ΣQ, the required compression value Ct, and the variable M.

Next, in step S11, it is determined whether or not the storage switch XS has been turned on (operation to the position indicated by the two-dot chain line shown in FIG. 9).
If YES for N operations, step S12
Then, from the suction work area where the suction work is performed by the suction pipe 22, the swivel pipe 41, the first flexible pipe 42, the tilting pipe 43, the telescopic pipe 44, and the second flexible pipe 45 are operated, respectively. After automatically storing 22 in the storage state (storage position), the process proceeds to step S13.

In step S13, the retreat switch T
It is determined whether or not S has been turned on (operation to the position indicated by the two-dot chain line in FIG. 9). If the evacuation switch TS has been turned on (YES), the suction pipe 22 is stored in step S14. From the position, the swivel tube 41, the first flexible tube 42, the tilting tube 43, the telescopic tube 44, and the second flexible tube 45 are respectively operated to automatically retract the suction tube 22 from the storage position to the suction work area. After the operation, the process proceeds to step S15.

In this step S15, the direct suction switch KS is turned on (operation to the position indicated by the two-dot chain line shown in FIG. 9).
It is determined whether or not the direct suction switch KS is
If YES for N operations, step S17
Then, the operator holds the vicinity of the tip of the suction pipe 22 with his / her own hand, directly sucks the trash G near the refuse suction truck V, and stores the refuse in the refuse storage tank 24.

Thereafter, the process proceeds to step S21 in FIG.
It is determined whether or not the tilt switch LS has been operated. If the tilt switch LS has been operated to the upper tilt position (the position indicated by the one-dot chain line in FIG. 9), the tilt cylinder 47 is extended and moved in step S22.
When the tilting cylinder 47 is contracted and moved to the lower tilting position (the position indicated by the two-dot chain line in FIG. 9) in step S24 after the tilting operation of the tilting tube 4 in step S24.
After the tilt switch 3 is moved downward, the process proceeds to step S24. If the tilt switch LS is not operated (NO), the process directly proceeds to step S24.

In step S24, the extension switch S
It is determined whether or not S has been operated, and if it has been operated to the extended position (the dashed-dotted line position shown in FIG. 9), the telescopic tube 44 is extended in step S25, then to step S27, to the contracted position (see FIG. 9). If the telescopic switch 44 is operated to the position indicated by the two-dot chain line), the telescopic tube 44 is contracted in step S26, and then the flow proceeds to step S27. If the telescopic switch SS is not operated, the flow proceeds to step S27.

In this step S27, the turning switch C
It is determined whether or not S has been operated, and if it has been operated to the right turning position (the dashed line position shown in FIG. 9), the turning pipe 41 is turned to the right in step S28, and then to step S30, the left turning position When the operation is performed to (the position indicated by the two-dot chain line shown in FIG. 9), the turning pipe 41 is turned to the left in step S29, and then to step S30, and when the turning switch CS is not operated, the processing proceeds to step S30. move on.

In this step S30, it is determined whether or not the compression plate switch AS has been operated, and if it has been operated to the pushing operation position (the position indicated by the dashed line in FIG. 9), the telescopic cylinder 52 is extended in step S31. The compression plate 51 is moved rearward (push operation) to move to the step S34. If the compression plate 51 is operated to the pulling operation position (the position indicated by the two-dot chain line in FIG. 9), the compression holding flag PF is set to "0" in the step S32. After clearing, the telescopic cylinder 52 is contracted and moved in step S33 to move the compression plate 51 forward (pulling operation).
If the result of determination in step 34 is that the compression plate switch AS has not been operated (NO), the flow directly advances to step S34. In this case, when making the determination in step S30, the determination in step S2 is NO, that is, the compression holding flag PF = 0.
If the determination in step S7 is NO, that is, if the open / close door switch OS is not operated to the open position, the amount of waste stored in the waste storage tank 24 is an amount that does not require compression by the compression plate 51. It is determined that there is a compression plate 5
1 is preliminarily positioned at the suction transport position. For example, when performing the suction transport operation after the garbage suction vehicle V travels and arrives at the next garbage storage, the above-described step S
After the compression plate switch AS is operated to the pulling operation position in 30 and the compression holding flag PF is cleared to "0" in step S32, it is not necessary to pull the compression plate 51 to the suction transport position in step S33. The waiting time required for the movement of the compression plate 51 is reduced, so that the garbage can be quickly sucked and transported.

In step S34, it is determined whether or not the open / close door switch OS has been operated. If the open / close door switch OS has been operated in the open position (the position indicated by the dashed line in FIG. 9), the open / close cylinder 48 is contracted in step S35 to open and close. If the door 46 is opened and the door 46 is operated to the closed position (the position indicated by the two-dot chain line in FIG. 9) in step S1, the opening and closing cylinder 48 is extended in step S36 to close the door 46. If NO in step S1 where the open / close door switch OS is not operated, the process directly returns to step S1. When the opening / closing door 46 is opened in step S35, the same processes as those in steps S8 and S9 are performed in advance.

On the other hand, at the time of the determination in step S1, for example, the garbage suction truck V is moved to another garbage storage X, and docking is performed in this garbage storage X in order to start the suction transportation of the garbage G from the vessel B. Station D
When the suction pipe 22 is connected to the coupling 21, the ON signal from the docking sensor DS is detected, so that it is determined that the moving operation of the garbage suction vehicle V is released, and Proceeding to S41, the compression holding flag PF is determined. This compression holding flag PF is “1”
In this case, since the dust G is kept in the compression holding state by the compression plate 51, the compression holding flag PF is cleared to "0" in step S42, and then the compression plate 51 is pulled forward to the suction transport position in step S43. .

Next, in step S44, the compression flag FLG is cleared to "0". This compression flag FL
G is for starting a compression routine when series compression is required in an automatic suction routine described later. Thereafter, in step S45, the automatic suction switch JS is turned on (operation to the position indicated by the two-dot chain line shown in FIG. 9).
Returning to step S1 is repeated until the automatic suction switch JS is turned on, and the process proceeds to step S46 to perform automatic suction.

Next, the automatic suction in step S46 is performed as follows.
Description will be made based on the automatic suction routine shown in FIG.

First, in step S51 in FIG. 5, the total number of vessels B in the refuse storage site X, for example, "10"
Is input to the counter CNT which is decremented and updated every time suction is completed, and the maximum value of the vessel number Bm which is decremented and updated every time suction of the vessel B is completed is displayed on the monitor 62 of the operation panel 30 like the counter CNT. In this case, the maximum value "No. 10" of the vessel number Bm is displayed on the monitor 62. However, when continuing the previous suction and transportation of the refuse G, the continuation number of the previous suction and transportation at the garbage storage X side. For example, when the previous suction / transport of the refuse G has ended at the vessel number B7, the monitor 62 displays the vessel number B6 (the maximum value of the current vessel number) at which the current suction / transport of the refuse G is started. Will be displayed. Therefore, 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. Therefore, the values of both variables do not always match. In this case, the connection between the suction pipe 22 and the docking station D allows the waste storage tank 24 and the vessel B to communicate with each other via the waste transport pipe 13, and the number and size of the vessels B in the waste storage area X. The information on the garbage storage site X side, such as the number of the vessel that previously suctioned and transported the refuse G and the length of the refuse transport pipe 13 to each vessel B, is transmitted to the control device 61 of the refuse suction vehicle V via the control signal cable. Is to be entered. Further, operation signals from the operation switches of the operation panel 30, the detectors of the vessel B, the pressure sensor 37, and the oil pressure sensor 5
The detection signal such as 0 is also transmitted to the control device 6 via the control signal cable.
1 can be input.

Next, in step S52, the input gate 8 of only the vessel B for starting suction transport of the refuse G is closed, and the discharge gate 14 is opened.
In step 3, the waste volume stored in the vessel B is written as the virtual waste amount Q based on the size of the vessel B. Thereafter, in step S54, the blower 33 of the suction device 23 is operated. Thereafter, in step S55, it is determined by the pressure sensor 37 whether the negative pressure of the blower 33 is a predetermined maximum negative pressure value, and the pressure in the vessel B is maintained until the negative pressure of the blower 33 becomes the predetermined maximum negative pressure value. Reduce the pressure. After completion of the depressurization in the vessel B, the process proceeds to step S56.

In step S56, a compression flag FLG for starting a compression operation routine described later is checked. If the compression flag FLG is "0", the flow advances to step S57. The secondary valve 18 is opened, and secondary air is introduced into the vessel B from the secondary air inlet 16. As a result, the refuse G in the vessel B is sucked and transported from the discharge gate 14 into the refuse storage tank 24 via the refuse transport pipe 13 and the suction pipe 22 while being tumbled, and a one-cycle suction pattern is performed.

Thereafter, in step S58, it is determined whether or not re-suction is required according to the size of the vessel B. If YES is determined that re-suction is required, the process returns to step S54 to change the suction pattern. On the other hand (in this case, the ON operation of the suction start operation switch is not necessary), and if not, the process proceeds to step S59. In this step S59, the cumulative capacity ΣQ of the virtual waste quantity Q when the suction transport of the waste G is performed over the plurality of vessels B, and the full capacity that can be stored in the waste storage tank 24 (the waste compression operation must be performed). If the capacity is equal to the tank capacity, but the capacity is larger than that for performing the garbage compression operation). In this case, garbage G
Is performed across a plurality of vessels B, the cumulative capacity ΔQ of the virtual waste amount Q increases each time the waste G is sucked and transported. Then, step S59
When the accumulated capacity ΣQ exceeds the full capacity of the refuse storage tank 24, the process proceeds to step S68, and the operation panel 3
0 is displayed on the monitor 62, and the control is terminated.
In this case, the accumulated capacity ΣQ is a variable that is cleared to “0” when the waste G in the waste storage tank 24 is discharged.

On the other hand, if the determination in step S59 is NO, in which the cumulative capacity ΣQ of the virtual waste quantity Q is smaller than the full capacity of the waste storage tank 24, step S59 is performed.
At 60, when the refuse G is sequentially sucked and transported into the refuse storage tank 24 according to a suction pattern that is repeatedly performed,
Inlet 40 of refuse storage tank 24 without refuse compression operation
The virtual waste amount Q is subtracted from a margin value M, which has a margin more than a limit value of the waste volume at which the waste G can be sucked without a blockage trouble in the vicinity. In this case, the margin value M is
Garbage storage tank 2 in the same way as the cumulative capacity of virtual waste amount QΣQ
4 is a variable that is initialized to a predetermined value when the dust G is discharged from the inside, and is an empirical value obtained by an experiment.

Then, at step S61, the sign of the subtraction value (M−Q) is determined to be positive or negative at step S60. If the virtual waste amount Q is smaller than the margin value M and the subtraction value (M−Q) is positive, the determination is NO. In this case, it is determined that the suction and transport of the refuse G is possible without performing the refuse compression operation, and the process proceeds to step S63.

On the other hand, if the virtual waste amount Q exceeds the allowance value M and the subtraction value (M−Q) becomes negative, the suction port 40 of the waste storage tank 24 will continue when the suction and transportation of the waste G is continued. It is determined that a blockage may be caused in the vicinity, and step S
Proceed to 62. Then, in step S62, the compression flag FLG in step S6 is set to "1". The compression flag FLG is initialized to “0” when the suction pipe 22 is connected to the docking station D for the first time.

Thereafter, in step S63, the counter CNT is checked to determine whether or not all the garbage G in all the vessels B of the garbage storage X has been sucked and transported. That is, even if suction transport is started from any vessel B subsequent to the previous suction transport of the refuse G, if the counter CNT is "1", it means that all the vessels B of the refuse storage area X have been cycled. Therefore, if the determination in step S63 is YES that the counter CNT = 1, in step S69, "Vessel suction end" is displayed on the monitor 62 of the operation panel 30, and the operator who has watched the display displays an automatic suction switch. The JS is turned off (operation to the position indicated by the solid line in FIG. 9) to stop the blower 33 of the suction device 23. On the other hand, the determination in step S63 is that the counter C
If NO is not NT = 1, the Bessel number Bm is decremented by one in step S64, and the process proceeds to step S65.

In this step S65, it is determined whether or not the vessel number Bm is equal to or less than "0", and the vessel number Bm is determined.
Is less than or equal to "0", the process proceeds to step S66.
Then, after returning the vessel number Bm to the maximum vessel number of the waste storage base X, the process proceeds to step S67. In step S67, the counter CNT is decremented by one, and the process returns to step S53, as in the case where the determination in step S65 is NO where the Bessel number Bm is larger than "0".

On the other hand, if the determination in step S56 is YES, that is, the compression flag FLG = 1, the process proceeds to step S56.
After performing the backwashing operation at 70, a dust compression operation is performed at step S71. After the refuse storage tank 24 is made negative pressure by this backwashing operation, the atmosphere release valve 36 is opened,
The outside air from the open pipe 35 is introduced into the refuse storage tank 24 through each of the suction ports 53 to 55 to remove the deposits and the refuse G near the first suction port 53 and to remove the refuse G in the suction pipe 22 to a docking station. Returning to the D side is performed once.

The dust compression operation in step S71 will be described later. After the dust compression operation is completed, in step S72, the compression flag FLG is cleared to "0", and the flow advances to step S73. In this step S73,
The compression request value Ct is subtracted by a fixed amount K. Thereafter, in step S74, it is determined whether or not the required compression value Ct is a lower limit value (lower limit value ≧ constant amount K). If YES in step S75, the required compression value Ct is the lower limit value. The required value Ct is set to the lower limit. Thereafter, in step S74, the required compression value Ct is not the lower limit value.
As in the case of (1), the process proceeds to step S76, and the initial value of the margin value M in step S60 is determined. Specifically, according to the size of the garbage storage tank 24, the garbage storage tank 2
The initial value of the margin value M is determined by the required compression value Ct which is reset to a predetermined value (initial required compression value) when the waste G in 4 is discharged. That is, the predetermined value of the required compression value Ct is the same as the initial value of the margin value M, and the margin value M which has become a negative value for performing the dust compression operation is returned to the value of the required compression value Ct.

Next, the compression operation of step S71 will be described with reference to the compression routine of FIG.

First, in step S81 in FIG. 6, the suction by the blower 33 is temporarily stopped. Then, step S
At 82, the telescopic cylinder 52 is extended to
1 is started to move backward (compression operation) toward the compression position (the position indicated by the two-dot chain line in FIG. 2), and time measurement is started in step S83.

Thereafter, in step S84, it is determined by the hydraulic pressure sensor 50 whether the hydraulic pressure of the telescopic cylinder 52 (the compression value of the compression plate 51) is equal to or higher than the hydraulic pressure limit value P1.
Y in which the oil pressure of the telescopic cylinder 52 is equal to or higher than the oil pressure limit value P1.
In the case of ES, it is determined that the dust compression operation by the compression plate 51 has been completed, and the process proceeds to step S85. On the other hand, if the determination in step S84 is NO in which the hydraulic pressure of the telescopic cylinder 52 is less than the hydraulic pressure limit value P1, the process proceeds to step S85.
In, it is determined whether the time measurement in step S83 has expired. In the determination of step S85, the amount of retreat movement of the compression plate 51 until the compression plate 51 reaches the maximum compression position is measured in time. By moving the compression plate 51 backward until the compression plate 51 reaches the maximum compression position, the dust compression operation is performed. To do.

If the determination in step S85 is NO that the time is not over, the process waits until the time is over.
Proceed to. In this step S86, the oil pressure of the telescopic cylinder 52 is increased by the oil pressure sensor 50 to a predetermined value P2 (P2 <P2).
1) It is determined whether it is the above or not. The determination in step S86 indicates that the hydraulic pressure of the telescopic cylinder 52 has reached the predetermined value P.
In the case of YES which is 2 or more, it is determined that the refuse G remains in the refuse storage tank 24 to some extent, and step S8 is performed.
7, the compression holding flag PF in step S23
Is set to “1”. Thereby, the above step S8
If the determination at 6 is that the oil pressure of the telescopic cylinder 52 is less than the predetermined value P2, it is determined that there is almost no waste G in the waste storage tank 24, and the compression holding flag PF is cleared to "0". Therefore, even if the suction pipe 22 is disconnected from the coupling 21 of the docking station D when the suction operation is completed and the suction pipe 22 is moved to another garbage storage site, the compression is not held by the moving compression plate 51. The time required for the pulling operation of the compression plate from the compression position to the suction / transport position in another waste storage site is reduced, and the suction / transport of the waste G can be performed quickly.

Thereafter, the determination in step S86 is
As in the case of NO where the oil pressure of the telescopic cylinder 52 is less than the predetermined value P2, the process proceeds to step S88,
At 88, the telescopic cylinder 52 is contracted to
Move 1 forward. Thereafter, in step S89, the compression plate 51 is moved to the suction transport position (the position indicated by the solid line in FIG. 2).
, The dust compression operation ends, and the process returns to step S1.

It should be noted that the present invention is not limited to the above embodiment, but includes various other modifications. For example, in the above-described embodiment, the suction transport operation for connecting the suction pipe 22 to the coupling 21 of the docking station D is detected by the ON signal of the docking sensor DS when the dust is sucked and transported by the garbage suction truck. By using a stop detection sensor that detects ON of the stop of the suction device and a parking release sensor that detects ON of parking release of the garbage suction vehicle, the moving operation of the garbage suction vehicle is detected, and the movement of the garbage suction vehicle is performed. When the operation is performed, the compression plate is moved from the suction transport position to the compression position based on the ON signals from both sensors to keep the waste in the waste storage tank in a compressed state, while the moving operation of the waste suction truck is performed. Is released, O from both sensors
Based on the FF signal, the compression plate may be moved from the compression position to the suction transport position so that the waste can be sucked and transported into the waste storage tank.
The same operation and effect as the embodiment can be obtained.

When an air hose extending from the suction device of the garbage suction truck is connected to the docking station, a detector for detecting connection or disconnection of the air hose is provided, and this detector detects a suction transport operation. Of course, you can do so.

Further, a sensor for detecting the retracted state or the retracted state of the suction tube may detect a suction transport operation or a garbage suction truck transport operation.

[0077]

As described above, according to the garbage suction / transport device of the first and second aspects of the present invention, when the garbage suction / carriage operation of the garbage suction vehicle is released, or when the garbage suction vehicle is moved. When the operation is performed, the compression plate is moved to the compression position to keep the refuse in the refuse storage tank in the compressed state. The waste from the waste storage container at the waste storage site is sucked and transported to the front of the compressed waste, thereby reliably preventing the waste from being blocked near the connection port of the transport pipe. In addition, the springback of the refuse itself due to running vibration or the like is regulated, and a storage space in the refuse storage tank is secured, so that the refuse storage efficiency can be improved.
On the other hand, when the suction transport operation of the refuse is performed, or when the moving operation of the refuse suction truck is released, the compression plate is moved from the compression position to the suction transport position to enable the suction transport of the refuse, and the following Suction and transportation of garbage when arriving at the garbage storage site can be performed smoothly.

According to the third aspect of the present invention, the compression plate is positioned at the suction transportation position when the amount of waste stored in the waste storage tank is such that compression and holding is unnecessary. The waiting time required to move the compression plate to the suction transportation position at the next garbage storage site can be reduced, and the garbage can be quickly transported by suction.

Furthermore, according to the fourth aspect of the present invention, when the rear wall is opened, the compression plate is moved to the suction transportation position side to reduce the compression force of the waste, thereby reducing the compression force of the waste. , The load on the lock portion of the rear wall can be reduced.
