Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a garbage loading device for a garbage collection vehicle.

(Prior Art) As is well known, a garbage loading device for a garbage collection vehicle has a tailgate pivotably attached to the vehicle body adjacent to an opening in the vehicle body, and a deflector, a scraping panel, etc. are installed inside the tailgate. It is provided.
In order to send the garbage dumped into the tailgate into the vehicle body, the scraping panel usually rises after the scraping operation and performs a pushing operation to push the garbage into the cargo box. .

The garbage loading cycle of this type of garbage loading device consists of reversing, retracting, lowering, scraping, raising, and pushing steps. In the conventional example, this cycle is completed by pushing, and the next cycle is started by reversing (for example,
(See Publication No. 129613).

(Problem to be Solved by the Invention) However, according to this cycle, all the loading mechanisms stop at the highest position inside the tailgate, and at this position, the center of gravity of the loading mechanism is quite high, and the vehicle tends to become unstable, making high-speed driving dangerous.

In view of the above points, it is an object of the present invention to stabilize the vehicle by ending the cycle of the loading mechanism at the complete loading position where the center of gravity of the loading mechanism is the lowest, and to prevent scraping inside the tailgate. To provide a garbage loading device for a garbage collection vehicle capable of collecting garbage in a space before raising a panel and improving storage capacity.

(Means for Solving the Problems) In order to achieve the above object, the garbage loading device for a garbage collection vehicle of the present invention includes a tailgate provided adjacent to a cargo box opening, and a garbage loading device supported within the tailgate. and a garbage loading mechanism including a garbage raking panel; and a control device including an electric circuit for controlling the garbage loading mechanism to reverse, lower, scrape, and raise the raking panel, and the control device includes: electrical means for disabling the electric circuit to automatically stop the operation of the dust loading mechanism before the lifting displacement of the scraping panel in its lowest position begins; and a switch for activating the electrical circuit to perform the operation.

(Function) When the electric circuit switch of the control device of the dust loading mechanism is activated, the dust scraping panel first starts to rise from the lowest position, carries the dust to the opening of the cargo box, and when it completes the rise, it lifts the dirt into the cargo box. It reverses in the direction away from the opening, then descends to scoop up the garbage thrown into the bottom of the tailgate.
At that point, it automatically stops and waits for the lowest position.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Fig. 1 and Fig. 2 which is a partial cross-sectional side view in principle.
The figure shows the state of the constituent parts of the garbage loading device of the present invention before the garbage loading operation starts. In the figure, reference numeral 1 denotes the body of a garbage collection vehicle, and a tailgate 2 is attached adjacent to an opening at the rear of the vehicle body as is well known. The tailgate 2 includes a pair of side plates 2a facing each other in the horizontal direction, a sump 2b constituting a bottom plate connecting the side plates, and beams 2c ₁ , 2c ₂ , 2c ₃ , etc. that integrally connect the side plates. It is configured.

It is pivoted to by a transverse pivot pin 5.

This pivot pin 5 has an ear piece 7a at the upper end of the side plate part 7 that is integrally provided at both lateral ends of the deflector 6.
is supported. As is known, the deflector 6 is a generally rectangular panel extending across the entire lateral width of the tailgate 2. A pair of guide rails 8 are attached to the inner surface of each side plate portion 7 at intervals in the longitudinal direction of the vehicle, and a guide groove 8a is formed between these guide rails in a substantially vertical direction. A protrusion 9a fixed along each side of the panel-shaped slider 9 is inserted into the guide groove,
The slider 9 is slidable in the longitudinal direction of the guide rail.

The upper side of a scraping panel 11 is pivotally attached to the lower side of the slider 9 by a pivot 10 . A mounting lug 12 is fixed to the tailgate 2 side surface of this scraping panel 11, and a mounting lug 13 is also fixed to the upper part of the tailgate side surface of the slider 9. The upper end of the cylinder 15a is pivotally connected to the ear piece 13 by a pin 16. The lower end of the piston rod 15b of the cylinder device 15 is pivotally connected to the lug 12 by a pivot pin 17.

The bracket 4 includes a vertically moving cylinder device 1.
The upper end of the cylinder 19a of 9 is pivotally connected by the aforementioned pivot pin 5, and the piston rod 19a is
The lower end of b is pivotally supported by the pivot 10. The vertically moving cylinder device 19 is housed inside the slider 9, for example inside its side frame 9b (FIG. 1).

Reference numeral 21 denotes a push-in cylinder device, the cylinder 21a of which is pivotally connected to the rear part of the tailgate 2 by a pivot pin 22, and the piston rod 21b
is pivoted on the pivot 10. The pin 22 is mounted on a mounting bracket ₂₃ fixed to the beam 2c2 of the tailgate 2.

A pivot pin 24 is supported on the mounting bracket 23, and the tip of a piston rod 26b of a tailgate dump cylinder device 26 is pivotally attached to this pin, and a cylinder 26a of the dump cylinder device 26 is attached to the pivot pin 24.
is pivotally connected to the bracket 4 by a pivot pin 27.

The cylinder devices 19, 21, 26, etc. described above are provided on each side of the tailgate side plate, and the scraping cylinder device 15 is provided at the center of the width of the slider 9. In addition, the sump 2 of the tailgate 2
An engaging portion 29 that is supported in contact with the rear edge of the floor portion 1a of the vehicle body 1 is provided at the front end of the vehicle body 1.

Next, the functions of the above-mentioned mechanical parts will be explained.

In the state shown in FIGS. 1 and 2, in which the loading operation has been completed but the loading cycle is still in progress, the pushing cylinder device 21 is extended, and the deflector 6, slider 9, scraping panel 11, etc. are moved around the pivot pin 5. It has moved forward to a position where it is slightly inside the vehicle body 1. Therefore, the dust inside the vehicle body is pushed deeper into the vehicle body, making it difficult for it to flow back toward the tailgate 2.

In this state, the reversing operation of the scraping panel 11 continues. For this purpose, the raking cylinder device 15 is retracted. As a result, the scraping panel 11 receives a force to rotate counterclockwise around the pivot shaft 10 via the pivot pin 17 and the mounting tab 12, and swings as shown by arrow A to the position shown in FIG. Take. In this way, since the scraping panel 11 is reversed within the vehicle body, the dust inside the tailgate is not blown out when the scraping panel is reversed, compared to when the scraping panel is reversed inside the tailgate. Even if there is a splash of dust, it will only fall onto the tailgate sump 2b.

Next, the push-in cylinder device 21 is retracted, thereby displacing the inverted push-in panel 11 in the direction indicated by arrow B. This displacement is a rotation about the pivot pin 5. The position thus obtained is as shown in FIG.

In this position, the vertical cylinder device 19 is extended. As a result, as the push-in cylinder device 21 rotates around the pivot pin 22, the push-in panel 11 is lowered as shown by arrow C to assume the position shown in FIG.

In the position of FIG. 5, a raking operation is performed by extending the raking cylinder device 15. In other words, the scraping panel 11 is aligned with the pivot 10 as shown by arrow D in FIG.
The tip portion 11a rotates around the sump 2b so as to be displaced along the upper surface of the sump 2b, thereby reaching the position shown in FIG. In the present invention, this scraping completion position is the cycle completion position, as will be described later. From this position, the vertical movement cylinder device 19 starts to contract, and the scraping panel 11 rises while scraping up the dust along the top surface of the sump 2b.
The position shown in Figure 7 is reached.

When the pushing cylinder device 21 is extended in this state, the deflector 6 and the pushing panel 11 are extended.
moves forward in the direction of arrow F toward the vehicle body while pushing the dirt, and is pushed in deeply, so that the above-mentioned effect can be obtained.

Incidentally, when discharging the dust collected in the vehicle body, the tailgate dump cylinder 26 is contracted in the state shown in FIG. 7. As a result, a counterclockwise moment corresponding to the product of the contraction force of the cylinder device 26 and the distance m between the pivot pins 5 and 27 (FIG. 2) acts around the pivot pin 5, and the tailgate 2 It rotates in the direction shown by arrow G in Figure 7 and is flipped up. Therefore, in this state, the collected garbage is discharged from the vehicle body.

As explained above, in order to sequentially operate the pushing cylinder device 15, the pushing cylinder device 21, and the vertical movement cylinder device 19, according to the present invention, a hydraulic circuit and an electric circuit, which will be explained from now on, are used. The various limit switches inserted therein will first be described with reference to FIG.

In the same figure, LS-6 is a limit switch that closes when the pushing cylinder device 21 is extended and the deflector 6 is in a state where pushing is completed.
It is supported by a support member 31 fixed to the deflector 6. A bell crank lever 33 is pivotally attached to the support member 31 by a pin 32, and the lower end of this lever 33 is configured as an actuator 33a that acts on a limit switch LS-6. on the other hand,
The upper end of the lever 33 is connected to a link 35 by a pin 34.
The base end of the link 35 is pivotally connected to the side plate 2a of the tailgate 2 by a pin 36. In the state shown in FIG. 8, the actuator 33
a contacts limit switch LS-6 and closes its contact.

On the other hand, when the deflector 6 rotates counterclockwise in FIG. 8, the bell crank lever 33 begins to rotate counterclockwise around the pin 32, and the actuator 33a releases the limit switch LS-6.
When the deflector 6 is completely rotated to the right, the actuator 33
a is further displaced and contacts the other limit switch LS-5 supported on the support member 31, closing its contact.

On the other hand, a support member 39 is also fixed to the slider 9, and limit switches LS-3 and LS-4 are supported and supported by this support member 39. In order to operate these limit switches, a dog-shaped link mechanism 40 is provided, one end of which is pivotally connected to the slider 9 and the other end of which is pivotally connected to the scraping panel 11. A central pivot portion of this link mechanism 40 constitutes an actuator 40a. In the state shown in FIG. 8, the actuator 40a contacts the limit switch LS-4 and closes its normally open contact.
On the other hand, the scraping panel 11 is
When the actuator 40a rotates counterclockwise around 0 and reaches the reversal completion position, the bending angle of the doglegged link mechanism 40 becomes smaller and the actuator 40a is displaced upward to act on the limit switch LS-3. This closes the normally open contact of limit switch LS-3.

At the top of deflector 6 is a limit switch LS.
-7, and at the bottom is the limit switch LS.
-8 is supported. Reference numeral 42 denotes an actuator fixed to the cylinder of the scraping cylinder device 15, which acts on limit switches LS-7 and LS-8. In the state shown in FIG. 8 in which the vertical movement cylinder device 19 is contracted, the actuator 42 is activated by the limit switch LS-
7 and closes its normally open contacts. On the other hand, when the vertically moving cylinder device 19 is extended and the slider 9 is completely lowered, the actuator 42 also lowers and acts on the limit switch LS-8. Limit switch LS-8 has its contacts closed by the action of actuator 42.

FIG. 9 shows a hydraulic circuit that is in charge of supplying pressure oil to the pushing cylinder device 15, pushing cylinder device 21, and vertical movement cylinder device 19 and discharging the pressure oil therefrom. The hydraulic power source includes a pump 45, to which a relief valve 46 is connected. 4
7 and 48 are 3-position electromagnetic switching valves with solenoid
Switching is performed by SOL1, SOL2 and SOL3, SOL4. When both the switching valves 47 and 48 are at their neutral positions, pressure oil is not sent beyond the switching valves.

Pipe lines 49 and 50 exit from the switching valve 47 and are connected to ports at both ends of the scraping cylinder device 15. On the other hand, the pipe 50 communicates with the oil reservoir via a relief valve 51, and the pipe 49 communicates with the oil reservoir via a check valve 52.

Pipe lines 53 and 54 also come out from the switching valve 48, and the pipe line 54 is connected to the upper port of the vertical movement cylinder device 19 and to the forward side port of the push cylinder device 21 via the pilot check valve 55, respectively. It's communicating. The pipe line 53 is a two-position electromagnetic switching valve 5
7 to a conduit 58, which is connected to a port on the rear side of the push cylinder device 21. A lower port of the vertically movable cylinder device 19 is connected to a switching valve 57 by a conduit 59.

FIG. 10 shows a control electric circuit including all solenoids SOL1 to SOL5 and all limit switches LS-3 to LS-8 of the aforementioned switching valve. In FIG. 10, CR1 to CR8 indicate relays, TDR1 and TDR2 indicate time delay relays, and KR1 and KR2 indicate keep relays for upward memory and push memory, respectively. Note that the normally open contact (a contact) and the normally closed contact (b contact) of each relay are shown by adding a number to the end of the code indicating the relay.

Next, the operation of the control device consisting of the hydraulic circuit and electric circuit described above will be explained.

To start operation, which begins with the rise from the raking completed state shown in Figure 6 to the rising completed state shown in Figure 7, first close the main switch MSW shown in Figure 10, and then press pushbutton switch PB1. . As a result, relays CR1 and CR2 are energized, and contacts CR1-1, CR1-2, CR1-3 of relay CR1 are energized.
closes, and contact CR2- of relay CR2 closes.
1, CR2-2 closes. By closing contacts CR1-2, the rotary solenoid RSOL is energized, which adjusts the engine throttle lever, increases the engine speed, and pumps the pump 4.
The discharge amount of No. 5 increases. Further, by closing contact CR2-1, a self-holding circuit 70 of relay CR1 is formed.

On the other hand, at this time, the scraping completion switch LS-4 is closed, so the relay CR4 is energized and its relay contact CR4-1 is closed. on the other hand,
Lowering completion switch LS-8 is also closed and relay CR
8 is energized and its relay contact CR8-3 is also closed. Therefore, contacts CR1-1, CR4-1,
The set side S of keep relay KR1 is energized via CR8-3, and keep relay contacts KR1-1,
KR1-2 close respectively. keep relay contact
When KR1-1 closes, the set side S of keep relay KR2 is energized, and keep relay contact KR2-1 is energized.
1 closes and keep relay contact KR2-2 opens.
By closing the keep relay contact KR2-1, the solenoid SOL4 is energized. On the other hand, the solenoid SOL5 is energized via the closed keep relay contact KR2-1 and the closed keep relay contact KR1-2. In this way, by energizing solenoids SOL4 and SOL5,
Since the switching valve 48 is switched to the right and the switching valve 57 is switched to the left, pressure oil is sent from the pump 45 through the switching valves 48 and 57 into the cylinder space below the vertical cylinder device 19, Device 19 begins to retract upwardly and all members begin to move toward the fully raised state of FIG.

When the ascent completion state shown in FIG. Contact CR7-2 opens. In this case, relay contact KR
Since 2-2 is open, relay contact CR7-1,
Opening and closing of CR7-2 does not particularly affect the operation, but by closing relay contact CR7-3, an input is applied to the reset side R of keep relay KR1 for rising memory, and keep relay KR1 is reset. Therefore, keep relay contact KR1-1,
KR1-2 opens, and the excitation of solenoid SOL5 is cut off by opening the contact KR1-2. but,
Even if the upward memory keep relay contact KR1-1 opens, the push memory keep relay KR2 is not reset, so the keep relay contact KR2-1 remains closed and the solenoid SOL4 continues to be energized. Therefore, only the switching valve 57 returns to the position shown in FIG. Pressure oil is sent into the right cylinder space of the device 21 through the switching valve 57, and the pushing cylinder device 21 begins to extend, and deep pushing begins from the lifted state shown in FIG. 7 to the pushed state shown in FIG. 2.

Upon completion of deep pushing, all parts reach the positions shown in Figure 2 or Figure 8, and the limit switch is turned on.
LS-6 is closed under the action of actuator 33a.
Therefore, relay CR6 is energized, relay contact CR6-3 is closed, and the push memory keep relay is activated.
An input is sent to the reset side R of KR2, and keep relay KR2 is reset. Therefore, keep relay contact KR2-1 opens and solenoid SOL
4 is cut off, and the extension of the push cylinder device 21 is stopped. On the other hand, the reset of keep relay KR2 closes its contact KR2-2. At this time, relay contacts CR8-1 and CR3-1 are
Since CR8 and CR3 are closed due to de-energization, and relay contact CR7-1 is closed due to the completion of lifting, solenoid SOL1 is connected to relay contact KR2.
-2, CR8-1, CR3-1, and CR7-1.

By energizing the solenoid SOL1, the switching valve 47 is switched to the left in FIG.
5 is supplied to the lower cylinder space, and the cylinder device 15 contracts. Therefore, the scraping panel 11 is reversed counterclockwise.

When the scraping panel 11 moves to the reversal completion position shown in Fig. 3, the limit switch LS-3 moves to the actuator 4.
Operated by 0a. That is, the reversal completion limit switch LS-3 is closed, the relay CS3 is energized, the relay contacts CR3-1 and CR3-3 are opened, and the relay contact CR3-2 is closed. Therefore,
The excitation of the reversing solenoid SOL1 is cut off, and the solenoid SOL3 is energized in its place, and in FIG. 9, the switching valve 47 returns to the neutral position, and the supply of pressure oil to the scraping cylinder device 15 is stopped, and the switching valve 48 moves to the left. Pressure oil is connected to pipe line 54 and pilot check valve 55.
It is then sent to the cylinder space on the left side of the pushing cylinder device 21, and the cylinder device 21 contracts.
Therefore, all the members are displaced backward toward the complete retreat position shown in FIG. 4. Also, the self-holding circuit of relay CR2 opens at contact CR3-3.

When the deflector 6 begins to rotate from the reversal completion position shown in FIG. 3 to the retraction completion position shown in FIG. 4, the closed limit switch LS-6 opens. In addition,
At the same time that pressure oil is supplied to the left cylinder space of the pushing cylinder device 21, the vertical cylinder device 1
The upper cylinder space 9 also communicates with the pressure oil source, but since its pressure oil return line 59 is closed by the switching valve 57, the vertically movable cylinder device 19 does not move.

When the member reaches the retraction completion position shown in FIG. 4, the retraction completion limit switch LS-5 is activated by the actuator 33a.
is pressed and closed, relay CR5 is energized, and its contact CR5-1 is closed. Contact CR5-1
By closing, solenoid SOL5 is energized, while solenoid SOL3 continues to be energized via relay contact CR3-2 since limit switch LS-3 is in the activated state and closed. The switching valve 5 is activated by energizing the solenoid SOL5.
7 is switched to the left from the position shown in FIG. 9, and therefore, the cylinder space below the vertically moving cylinder device 19 communicates with the oil reservoir via the pipe 59, the switching valve 57, and the pipe 53. The vertically movable cylinder device 19 extends downward due to the hydraulic pressure that continues to act on the cylinder space above it. In addition, since the pipe line 58 is closed by switching the switching valve 57, the pushing cylinder device 21 does not move. Thus,
All members are displaced from the retracted state shown in FIG. 4 to the lowered state shown in FIG. 5.

By reaching the lowering completion position shown in FIG.
Touch LS-8 to activate it. Limit switch LS-8 closes when actuated by actuator 42, energizing relay CR8, which opens relay contacts CR8-1 and CR8-4 and closes relay contacts CR8-2 and CR8-3. Therefore,
The excitation of solenoid SOL3 and solenoid SOL5 is cut off, the switching valve 57 moves to the right and closes the pipe line 59, thereby stopping the downward extension of the vertical cylinder device 19, and relay contact CR8
-2, the thrust solenoid SOL2 is energized. In addition, even if contact CR8-4 opens, the relay will not work.
CR1 continues to be self-held by circuit 71. By energizing the solenoid SOL2, the switching valve 47 moves to the right from the neutral position in FIG. 9, and the pressure oil from the pump 45 is sent into the cylinder space above the scraping cylinder device 15 through the pipe 50. Therefore, the raking cylinder device 15 extends downward, and raking is performed from the lowered state shown in FIG. 5 to the raked completed state shown in FIG. On the other hand, at the lowering completion position, time delay relay TDR1 is closed due to relay contact CR8-2 being closed.
begins to be excited. The setting time of this relay is a little longer than the normal scraping time.

When the scraping panel 11 reaches the scraping completion state shown in FIG. 6, the scraping completion limit switch LS-4 is closed by the action of the actuator 40a. Therefore, relay CR4 is energized and relay contact CR4-
1 closes. At this time, the lowering completion limit switch
Since relay contact CR8-3 is already closed by the closing of LS-8, the keep relay for rising memory KR
The set side S of 1 is energized and the keep relay contact
KR1-1 and KR1-2 close respectively. However, when relay CR4 is energized, relay contact CR4-
By opening 2, relay contact CR1-1, TDR
Since the circuit of relay CR1 which was energized via self-holding circuit 71 including CR1-2 and CR4-2 is opened at relay contact CR4-2, relay CR1
1 is demagnetized, relay contacts CR1-1, CR1-2
opens, the electrical circuit becomes inactive, the entire process is completed, and everything stops. When the dust reaction force acting on the scraping cylinder device 15 during scraping exceeds a set value, an unloading action is performed by the relief valve 46, so that no unreasonable force is applied to the scraping panel 11. In addition, when the scraping does not end in the normal time due to excessive dust reaction force, the relay contacts TDR1-2 open as the time delay relay TDR1 times up, and the self-holding circuit 71 of the relay TRR1 opens. The cycle is completed as well.

If dust is trapped in the sump section and is interfering with normal scraping operation, turn the reversing button switch.
Operate PB3 to perform an independent reversal operation of the scraping panel 11. When the reversing button switch PB3 is operated, the supply of electricity to the relays CR1 and CR2 is cut off, so that the relays CR1 and CR2 are demagnetized.
This stops the scraping operation. At the same time, electricity is supplied to the rotary solenoid through the circuit 72 and to the solenoid SOL1 through the circuit 73, so that only the scraping panel performs the reversing operation until the reversing button switch PB3 is released.
When the reversing button switch PB3 is released, no electricity is automatically supplied to the relays CR1 and CR2, so all operations remain stopped.

Next, to restart the loading operation, push button switch PB1 can be pressed. If the reversal is restarted from the middle of the reversal, relays CR1 and CR2 will immediately self-hold, and if the reversal is restarted from the completion of the reversal, only the relay CR1 will be self-held immediately and the scraping process will restart.

To restart the garbage loading cycle, press pushbutton switch PB1 as previously described. This re-energizes relays CR1 and CR2 and repeats the same loading cycle as described above.

[Effects of the Invention] As described above, in the present invention, the garbage loading cycle ends in the state in which the raking is completed as shown in FIG. In this state, the garbage collection vehicle can be driven stably to the garbage treatment plant even at high speeds, and the garbage storage capacity can be increased.
