Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust loading device for a dust truck, which is capable of efficiently loading dust by compressing dust that is difficult to compress such as plastic.

[0002]

2. Description of the Related Art In a conventional garbage truck for collecting garbage,
Garbage is loaded by throwing it in from the tailgate, scraping it into the garbage room, and compressing the garbage in the garbage room for a certain period of time.

[0003]

Since the garbage has a high compression rate, it can be sufficiently compressed only by compression in the garbage chamber, and a large amount of garbage can be loaded in the garbage chamber.

[0004] However, plastic waste is not only bulkier than raw waste, but is put into a waste collection vehicle, and it is harder than raw waste and has a low compression rate, so it is sufficient in the waste room. It cannot be compressed. Also,
Since the compression in the garbage chamber does not continue, the repulsive action of the garbage itself causes it to return to a bulky state. Therefore, in the past, the plastic waste had to be collected and transported in a bulky state with extremely poor loading efficiency. The present invention has been made in view of such circumstances, and it is possible to sufficiently compress dust such as plastic having a low compression rate and to maintain the compressed state, thereby efficiently loading a large amount of dust. The object is to provide a device that can be collected and transported.

[0005]

In view of the above, according to the present invention, there is provided a dust receiver for receiving dust thrown in through a dust inlet of a vehicle body, and a dust receiver disposed above the dust receiver to rotate the dust receiver so that the dust is received on the dust receiver. Pushing plate for scraping up the waste toward the dust chamber, a swing plate disposed above the pushing plate for scraping the dust scraped up by the pushing plate into the dust chamber while compressing the dust, and the swing plate In a waste recovery vehicle having a compression plate that forms the waste chamber with the swing plate and compresses the waste scraped into the waste chamber by the swing plate to a predetermined pressure, the waste receiver can be raised and lowered freely. In addition, a restraint plate that opens and closes a passage between the dust receiver and the dust chamber is provided above the dust receiver, and when dust is thrown onto the dust receiver, the restraint is performed. While the plate is in the closed state, the pushing plate is rotated to a position where dust on the dust receiver is suppressed by the pushing plate, and the dust receiver is raised, whereby the holding plate, the pushing plate, and the By forming a chamber for compressing the dust on the dust receiver with the dust receiver to compress the dust in the dust compression chamber, and then with the pressing plate in the open state, by further rotating the pushing plate, A controller for driving and controlling the pressing plate, the pushing plate, and the dust receiver is provided so as to scrape up the compressed dust from above the dust receiver toward the dust chamber.

[0006]

According to this structure, as shown in FIGS.
As shown in (c) and FIG. 9 (d), when the dust 20 is put on the dust receiver 1, the pressing plate 3 is closed, and the pushing plate 2 is placed on the dust receiver 1 by the pushing plate 2. Garbage 2
It is rotated to a position where 0 is suppressed and the dust receiver 1 is raised. As a result, the pressing plate 3, the pushing plate 2, and the dust receiver 1 form a chamber 8 for compressing the dust 20 on the dust receiver 1, and the dust 20 in the dust compression chamber 8 is compressed. At this time, even if the dust such as plastic has a low compression rate,
It is compressed enough to retain the compressed state.

Then, the pressing plate 3 is opened and the pushing plate 2 is further rotated. As a result, compressed garbage 2
0 is scraped up from above the garbage receiver 1 into the garbage room 9 and loaded into the garbage room. As a result, a large amount of compressed waste can be loaded into the waste chamber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a waste loading device in a waste recovery vehicle according to the present invention will be described below with reference to the drawings.

FIG. 3 is a diagram showing the construction of the waste loading device of the embodiment, which is a cross-sectional view of the rear side surface of the waste recovery vehicle.

As shown in FIG. 3, the device of the embodiment is similar to the conventional dust loading device, and is the dust 20 thrown in from the dust inlet provided in the tailgate 13 of the vehicle body as shown by an arrow G. The garbage receiver 1 that receives the waste, and the garbage 20 that is disposed above the garbage receiver 1 and rotates in the clockwise direction as shown by an arrow D about the rotation shaft 2a as a center of rotation, so that the garbage 20 on the garbage receiver 1 is disposed in the garbage chamber Push-in plate 2 that is lifted up inward
And the dust 20 disposed above the pushing plate 2 so as to be swingable as shown by an arrow F and scraped up by the pushing plate 2.
Swing board 4 for scraping scraps into the garbage chamber 9
And a compression plate 5 that forms a dust chamber 9 together with the swing plate 4 and that compresses dust 20 scraped into the dust chamber 9 by the swing plate 4 to a predetermined pressure. here,
The compression plate 5 is moved as indicated by an arrow X by driving the hydraulic cylinder 7. The swing plate 4 is swung by driving the hydraulic cylinder 11.

The embodiment apparatus further has the following characteristic structure.

That is, the lower portion of the dust receiver 1 is connected to the rod of the hydraulic cylinder 10, and the rod can be raised and lowered as shown by an arrow C by expanding and contracting the rod.

Further, above the dust receiver 1, there is provided a restraining plate 3 which is opened and closed by moving the passage between the dust receiver 1 and the dust chamber 9 as shown by an arrow E.

A hydraulic cylinder 10 for driving the dust receiver 1,
A controller 6 drives and controls an actuator that drives the pushing plate 2, an actuator that drives the pressing plate 3, a hydraulic cylinder 11 that drives the swing plate 4, and a hydraulic cylinder 7 that drives the compression plate 5.

Here, the control of the compression of the dust 20 in the dust chamber 9 is performed as follows. That is, the hydraulic cylinder 11 is provided with the pressure sensor 12 that detects the pressure P0 of the pressure oil in the cylinder chamber of the hydraulic cylinder 11. Therefore, the controller 6 uses the pressure sensor 1
A signal indicating the detected pressure P0 of 2 is input, and a drive command signal is output to the hydraulic cylinder 7 so that the output (feedback amount) of the pressure sensor 12 matches the target pressure to move the compression plate 5. Control the quantity X. Therefore, when the dust 20 is scraped into the dust chamber 9 by the swing plate 4, the dust 20 in the dust chamber 9 is compressed to the target pressure.

Although the compression plate 5 is moved by hydraulic pressure in FIG. 3, it may be moved by pneumatic pressure as shown in FIG. 4 that are the same as those in FIG. 3 are the same components.

In the case of FIG. 4, the controller 6'inputs a signal indicating the pressure P0 detected by the pressure sensor 12, and the air supply device so that the output (feedback amount) of the pressure sensor 12 matches the target pressure. A drive command signal V is output to (not shown) to apply an air pressure P to the compression plate 5.
Control one. Therefore, the swing plate 4 causes the waste 2
When 0 is scraped into the dust chamber 9, the dust 20 in the dust chamber 9 will be compressed to the target pressure.

Now, the controllers 6 and 6 ′ are disposed of the waste 20.
Is sufficiently compressed in advance, and then the dust receiver 1 and the like are drive-controlled so as to scrape the dust into the dust chamber 9.

This control will be described with the apparatus shown in FIG. 3 as a representative with reference to the flow charts shown in FIGS. 1 and 10 and the timing chart shown in FIG.

As a premise of the description, the drive position of the pushing plate 2 and the like will be defined as shown in FIGS.

That is, as shown in FIG. 5, the pushing plate 2
The vertical upper rotation position is 0 ° (360 °), the horizontal right (rear vehicle body) rotation position is 90 °, the vertical lower rotation position is 180 °, and the horizontal left (front vehicle body) rotation position is 270.
Defined as °.

Further, as shown in FIG. 6, for the swing 4, the swing position for closing the passage between the dust receiver 1 and the dust chamber 9 is "closed", and the swing position for opening the passage is "open". It is defined as

Further, as shown in FIG. 7, with respect to the restraining plate 3, the moving position for partially covering the upper surface of the dust receiver 1 and closing the passage between the dust receiver 1 and the dust chamber 9 is set to "close". The moving position where the upper surface of the receiver 1 is opened and the passage between the waste receiver 1 and the waste chamber 9 is opened is defined as "open".

Further, as shown in FIG. 8, for the dust receiver 1, the position where the dust receiver 1 is fully raised is referred to as "top dead center",
The position where the dust receiver 1 is completely lowered is defined as "bottom dead center".

Therefore, as shown in FIG. 1 (a), when the process is started, the timer is first reset to zero (step 101), and thereafter the time counting by the timer is started (step 102). At time t = 0 (= T0), as shown in FIG.
As shown in, the pushing plate 2 is stopped at 270 °, the swing plate 4 is closed, the pressing plate 3 is open, and the dust receiver 1 is stopped at the bottom dead center position. Therefore, as shown in FIG. 9 (a), the pushing plate 2 is stopped in a state in which the dust has been scraped up toward the inside of the dust chamber 9, and of the upper surface of the dust receiver 1 on the inlet side ( The rear side of the vehicle) is open. Therefore, in this state, the dust 20 can be thrown into the dust receiver 1 from the dust inlet of the tailgate 13 as shown by an arrow G.

The timer sequentially determines whether or not the preset time t1 is measured (step 103), and at time T1 when it is determined that the preset time t1 has elapsed, the pushing plate 2 starts to rotate (step 103). 104; FIG. 2 and FIG.
(See (a)).

Then, the rotational position of the pushing plate 2 is 360 °.
(Rotation position where swing plate 4 and pushing plate 2 do not interfere)
Whether or not it is determined, for example, is sequentially determined based on the output of the sensor that detects the rotational position of the pressing plate 2 (step 105), and at time T2 when the pressing plate 2 rotates to 360 ° (see FIG. 2). ), The swing plate 4 starts swinging toward the open position. At the same time, the pressing plate 3 starts moving toward the closed position (step 106; see FIG. 9B). The section until the push-in plate 2 reaches 360 ° is the process of throwing the dust 20 into the dust receiver 1, and dust can be thrown in. However, when this process ends, the dust 20 on the dust receiver 1
Is entered (see FIG. 2).

It is sequentially determined whether or not the rotational position of the pushing plate 2 has reached 90 °, that is, the rotating position where the dust 20 on the dust receiver 1 can be suppressed by the pushing plate 2 (step 107).

Further, whether or not the swing position of the swing plate 4 is in the open position is sequentially determined based on, for example, the output of the sensor that detects the swing position of the swing plate 4 (step 109).

Further, whether or not the moving position of the pressing plate 3 has become the closed position is sequentially determined based on, for example, the output of the sensor that detects the moving position of the pressing plate 3 (step 1).
11).

Therefore, when it is determined that the pushing plate 2 has been rotated up to 90 °, the rotation of the pushing plate 2 is stopped (step 108), and it is determined that the swing plate 4 has been swung to the open position. Then, the swing of the swing plate 4 is stopped (step 110), and when it is determined that the holding plate 3 has been moved to the closed position, the movement of the holding plate 3 is stopped (step 112).

Then, these steps 107 to 11
After the process of 2, the pushing plate 2 is rotated up to 90 °, the swing plate 4 is swung to the open position, and it is confirmed whether or not the restraining plate 3 is moved to the closed position (step 113). . If this confirmation is possible, the process proceeds to the next step 114. If the confirmation is not possible, the procedure proceeds to step 107 again and the same processing is executed.

Time T at which the above step 113 was confirmed
In 3 (see FIG. 2), the positional relationship is as shown in FIG. 9 (c). As a result, the pressing plate 3 and the pushing plate 2 suppress the upper surface of the dust 20, and the dust receiver 1 suppresses the side surface and the bottom surface of the dust 20. As a result, the chamber 8 for compressing the dust 20 on the dust receiver 1 is formed.

In this state, when the dust receiver 1 is raised (step 114; see FIG. 9C), the dust 20 in the dust compression chamber 8 is compressed. At this time, even the dust 20 such as plastic having a low compression rate is sufficiently compressed so that the compressed state is maintained.

Whether or not the moving position of the dust receiver 1 has reached the top dead center is sequentially determined based on, for example, the output of a sensor that detects the moving position of the dust receiver 1 (step 11).
5).

When it is determined that the dust receiver 1 has reached the top dead center, the timer is reset to zero as shown in step 116 of FIG. 10, and the time counting by the timer is started thereafter (step 117). ). That is, time T4
When the garbage receiver 1 reaches the top dead center, the compression stroke ends,
Thereafter, the process of holding the dust 20 in a compressed state is started (see FIG. 2).

When the timer measures the preset time t2 (holding time) (YES at step 118), the pressing plate 2 starts rotating and the holding plate 3 starts moving toward the open position. (Step 119; FIG. 9
(See (d)). That is, when the holding time t2 elapses at time T5, the holding process ends, and thereafter, the waste 20 is removed from the waste chamber 9
Enter the process of scraping toward (see Figure 2).

It is successively judged whether or not the moving position of the pressing plate 3 is the open position (step 120).

Further, it is successively judged whether or not the rotational position of the pushing plate 2 is 270 ° (step 12).
2).

When it is determined that the holding plate 3 has been moved to the open position, the movement of the holding plate 3 is stopped (step 121), and it is determined that the pushing plate 2 has been rotated to 270 °. The rotation of the pushing plate 2 is stopped (step 123).

Then, these steps 120 to 12
After the processing of step 3, it is confirmed that the pressing plate 3 has been moved to the open position and that the pressing plate 2 has been rotated by 270 ° (step 124). If this confirmation is possible, the process proceeds to the next step 125. If the confirmation is not possible, the procedure proceeds again to step 120 and the same processing is executed.

Time T at which the above step 124 was confirmed
6 (see FIG. 2) has a positional relationship as shown in FIG. 9 (d). As a result, the scraping of the dust 20 into the dust chamber 9 by the pushing plate 2 is completed. From time T6, the scraping process is shifted to the process of scraping the dust 20 into the dust chamber 9 by the swing plate 4 (see FIG. 2).

That is, the swing plate 4 starts swinging toward the closed position. At the same time, the dust receiver 1 starts descending toward the bottom dead center (step 125; see FIG. 2 and FIG. 9E).

It is successively determined whether or not the swing position of the swing plate 4 is at the closed position (step 126).

Further, it is successively judged whether or not the moving position of the dust receiver 1 is at the bottom dead center (step 128).

Therefore, when it is determined that the swing plate 4 is swung to the closed position, the swing of the swing plate 4 is stopped (step 127), and it is determined that the dust receiver 1 is moved to the bottom dead center. Then, the movement of the dust receiver 1 is stopped (step 129).

Then, these steps 126 to 12
After the processing of 9, the swing plate 4 is swung to the closed position,
It is confirmed whether or not the dust receiver 1 has been moved to the bottom dead center (step 130). Time T when this confirmation was made
The scraping process ends at 7 (see FIG. 2), the procedure moves to step 101 in FIG. 1 again, and the same processing is repeated from the first refuse charging process. Note that the above step 13
If 0 is not confirmed, the procedure is again step 1
Then, the processing shifts to step 26 and the same processing is executed.

Time T at which the above step 130 was confirmed
7 (see FIG. 2) has a positional relationship as shown in FIG. 9 (e). At this time, the dust 20 is scraped into the dust chamber 9, and the dust in the dust chamber 9 is compressed to the target pressure as described above so that the dust 20 does not flow backward.

When the dust 20 is discharged to the outside of the vehicle, the compression plate 5 may be moved to the inlet side of the tailgate 13 to push out the dust 20 in the dust chamber 9.

In the embodiment, the hydraulic cylinder and the air supply device are used as the actuators for driving the respective parts, but any actuator other than these may be used.

When the compression of the dust 20 in the compression chamber 8 is unnecessary, the dust receiver 1 is fixed at the top dead center and the pressing plate 3 is fixed in the open state, as in the prior art. You may load garbage. in this case,
Since the compression process is omitted, the cycle time of waste collection can be shortened and the work efficiency can be improved.

[0052]

As described above, according to the present invention,
Since it is possible to sufficiently compress dust such as plastic having a low compression rate and to keep the compressed state, it is possible to efficiently collect and transport a large amount of dust.
