Description

[Detailed description of the invention] The present invention relates to a garbage loading device for a garbage collection vehicle.

The garbage loading device of the garbage collection vehicle includes a tailgate 1' pivotally connected to the vehicle body adjacent to the opening of the vehicle body in a known manner.
! However, a deflector, scrape-in panel, etc. are installed inside this tailgate. In order to send the garbage dumped into the tailgate into the vehicle body, the raking / 9-nel usually rises after the raking operation, turns into the cargo box, and performs a pushing operation to push the garbage. It is.

However, during this pushing operation, as the amount of loaded garbage increases, the pushing operation becomes difficult.
The reaction force acting on the push-in panel and push-in cylinder device increases, resulting in an overload condition.

When this situation occurs, the panel will be scraped.

The deflector, etc., cannot perform a sufficient pushing displacement and stops midway.In this case, the loading device operates in the IJ-7 state because no signal indicating completion of pushing is issued. This not only causes a loss of power, but also delays the start of the next loading, which causes a decrease in work efficiency.

The present invention improves work efficiency by automatically turning off the control circuit and ending the loading cycle after a predetermined period of time (after a predetermined period of time has elapsed), without waiting for the completion of loading when a difficult situation occurs. This is what we are trying to measure.

Hereinafter, the present invention will be described in detail with reference to FIG.

FIG. 1 and FIG. 2, which is a partial cross-sectional view of the principle, show the state of the rock structure portion of the garbage loading device of the present invention before the garbage loading operation starts. Circular 1 is the body of a garbage collection vehicle,
A well-known tailgate 2 is attached to the opening at the rear of the vehicle body. The tailgate 2 is composed of a pair of side plates 2a facing each other in the horizontal direction, a sump 2b forming a bottom plate connecting the side plates, and a beam 2css2c2t2ca etc. that integrally connects the two side plates. ing. The tailgate 2 is pivotally connected to brackets 4 fixed near both ends of a profile 30 laterally fixed to the rear of the vehicle body 1 by means of a lateral pivot pin 5.

On this pivot pin 5, the upper end tabs 7m of the side plate portions 7 at both lateral ends of the deflector 6 are pivotally supported. As is known, the deflector 6 is a generally rectangular armpit extending over the entire lateral width of the tailgate 2. A pair of guide rails 8 are attached to the inner surface of the side plate portion 70 at a distance t, and a guide groove is formed between these guide rails in the vertical direction. i! In the idle groove circle, there are protrusions 9 fixed to each side of the slider 9 in the form of a buttock.
m is inserted, and slide/9 is slidable in the longitudinal direction of the guide rail.

The upper side of the scraping groove 11 is pivotally attached to the lower side of the slider 9 by means of a pivot 10 . IfrK of the tailgate 2 of this pull-in armpit 11 is the mounting ear piece 12.
On the other hand, a mounting lug 13 is also fixed to the upper part of the tailgate side surface of the slider 9, and the upper end of the cylinder 15m of the scraping cylinder/device 15 is pivotally attached to the lug 13 by a pin 16. There is. The lower end of the piston rod 15b of this cylinder/instrument 15 is pivotally connected to the lug 12 by means of a pivot pin 17.

The upper end of the cylinder/19a of the vertically movable cylinder device 19 is pivotally attached to the bracket 4 by the aforementioned pivot pin 5, and the lower end of the piston rod 19b is pivoted to the aforementioned pivot pin 5.
It is pivoted to 0. The vertically moving cylinder device 19 is housed inside the slider 90, for example inside its frame 9b (FIG. 1).

21 is a pushing cylinder device, and its cylinder/21
a is pivotally connected to the rear part of the tailgate 2 by a pivot pin n, and its piston rod 21b is pivotally supported by the pivot 10VC. The pin n is provided on a mounting bracket 23 fixed to the beam 2c2 of the tailgate 2.

A pivot pin is supported on the mounting bracket (23), and the tip of the piston rod 26b of the tailgate danzo cylinder device I is pivotally attached to this pin, and the cylinder/26m of the cylinder device 126 is supported by the pivot pin IK. Therefore, it is pivotally attached to the bracket 4.

The cylinder devices 19, 21, 26, etc. described above are
The scraping cylinder device 15 is provided at the center of the width of the slider 9. A retainer is provided at the end of the sump 2b I) of the tailgate 2 and is supported in contact with the rear end edge of the floor portion III of the vehicle body I.

I will now explain the functions of the above-mentioned mechanical parts.

In the state shown in FIGS. 1 and 2, which is the state before the start of the loading operation, the pushing cylinder device [21] is extended, and the deflector 6, slider 9% push-in panel 11, etc. are slightly pushed into the vehicle body 10 around the pivot bin 5. It is moving forward to the position where it can enter. 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 rake/four channel 110 reversal operation is started. For this purpose, the raking cylinder device 15 is retracted. This allows the pivot pin 17. The armpit 11 receives a counterclockwise rotational force around the pivot 10, swings as shown by arrow A, and assumes the position shown in FIG. 3. Like this K.

Since the scraping knob 11 is reversed inside the vehicle body, unlike the scraping knob 74 which is reversed inside the tailgate, it does not blow out the dust inside the tailgate when the tailgate is reversed. Even if there is a splash of dust, it will only fall onto the tailgate sp/2b.

After a while, the push-in cylinder device 21 is contracted hl, and as a result, the inverted push-in panel 11 is displaced in the direction indicated by the arrow 1. This displacement is a rotation about the pivot 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 4, the push-in armpit 11 descends as shown by arrow C and assumes the position shown in FIG.

In the position of FIG. 5, a raking operation is performed by extending the raking cylinder device 15. That is, the scraping panel 11 performs scraping by rotating around the axis lO so that the tip 11m is displaced along the upper surface of the sump 2b, as shown by the arrow in FIG. reach. From this position, the vertical movement cylinder device 19 starts to contract, and the armpit flange l! 1 cup along the top of sump 2b! It rises while stirring and reaches the position shown in Figure 7.

When the pushing cylinder device 21 is extended in this state, the deflector 6 and the scraping arm 11 move forward in the direction of the arrow F17) into the vehicle body while pushing the debris, and are pushed deeply, so that the above-mentioned effect can be obtained. It will be done.

In addition, when discharging the garbage collected inside the vehicle, please use the seventh
Contract the tailgate Danzo cylinder 26 in the state shown in the figure. 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 is moved to the seventh position. It rotates in the direction shown by arrow G in the figure and is flipped up. Therefore, in this state, the collected dust is discharged to the outside of the vehicle body.

As explained above, the pushing cylinder device 15, the pushing cylinder device 21. Vertical cylinder device 19 1@
For the next actuation, according to the invention, a hydraulic circuit and an electric circuit are used, which will now be described.
This will be explained with reference to FIG.

In the figure, L8-1 indicates M[ when the pushing cylinder device 4 is extended and the deflector 6 is in the state 11 when pushing is completed.
It is a closing limit switch and is supported by a support member 31 that is fixed to the deflector 6.

On the other hand, the upper end of the renosee north is pivotally connected to the tip of the link by means of a pin, and the base end of this link is pivotally connected to the side plate 21K of the tailgate 2 by means of a pin 36. In the state shown in Fig. 8, the actuator 33a contacts the IJt switch L8-IK and closes its connection.On the other hand, when the deflector 6 rotates counterclockwise in Fig. 1Ii8, the bell crank blades are The actuator 331 releases the limit switches L and 8-14' and the actuator 33m is further displaced to the support member 31 when the deflator 6 is completely rotated to the right. The other 13 who supported it? contact switch L8-5 and close its contacts.

On the other hand, a support member is also fixed to the slide/9, and the Mitswitches L8-4 and L8-8 are supported by this.

In order to operate these limit switches V, one end is pivotally connected to the slide/9 and the other end is pulled in).

At the position where the vertical movement cylinder device 19 is extended and the slider 9 is completely lowered, the actuator 42 also lowers and acts on the limit switch L8-6. Limit switch LS-6 has its contacts closed by the action of actuator 420.

FIG. 9 shows a hydraulic circuit that is in charge of supplying pressure oil to the pushing cylinder device f15, the pushing cylinder device 21, and the 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. 47.48 is a 3-position electromagnetic switching valve with solenoids 80L1, 80L2, 80L3, 80L4
At the neutral position of the 0-way switching valves 47 and 48, where KL switching is performed, pressure oil is not sent beyond both switching valves.

Pipe lines 49 and 50 exit from the switching valve 47 and are connected to both ends of the scraping cylinder device 150.

On the other hand, the pipe line (material) communicates with the oil reservoir via the relief valve 51t', and the pipe line 49 communicates with the oil reservoir via the check valve 52, respectively.

Pipe lines 53 and 54 also come out from the switching valve, and the pipe M is connected to the I-toe above the vertical movement cylinder 4P@@19, and to the forward side of the push-in cylinder device 4 via the noso-eat check valve 55V. /-) are also connected to each other.

Next, the operation of the control device consisting of the hydraulic circuit with a Kdi of 5 or more and the electric circuit shown in FIG. 10 will be explained.

Scraping panel 11 from the state shown in Figure 2 to the state shown in Figure 3
The start of operation begins with the reversal of the
After closing the main switch MOW shown in Figure 0, press the push button switch PBt/. This (therefore, relay CRI,
CR2 is energized, relay CR1F>contact CR1',
CRI't-CRI'' closes and relay CR
2 contacts CR2' and CR2' close. At this time, the ascent completion limit switch L8-9 is closed, and the relay C
Since R7 is energized and its relay contact CRT' is closed, the closed contacts CR1', KR2', CR

Reversing solenoid 5OLI via CR3', CR7'
is excited. On the other hand, when the contact CRI' closes, the rotary linenoid R80L is energized, which causes the engine's throttle linenoid R80L to be energized. -b-g section sre, engineering/
The engine rotation speed increases, and the discharge amount of the pump 45 increases.

By energizing the solenoid 80L1, the °C switching valve 47 is switched to the left in FIG.
9) L d is supplied to the lower cylinder space of the cylinder device 15, and the cylinder device 15 contracts. Therefore, the raking armpit 11 is reversed counterclockwise.

When the pull-in armpit 11 moves to the reversal completion position shown in FIG. 3, the limit switch L8-4 is actuated by the actuator 40aK. That is, when the reversal is completed 13, the switch L8-4 is closed, the relay CR3 is energized, the relay contact CR3' is opened, and the relay contact CR3' is closed. Therefore, the excitation of the reversing solenoid 80L1 is cut off, and the solenoid 80L3 is energized instead, and the switching valve 4 in FIG.
7 returns to the neutral position, the supply of pressure oil to the pushing cylinder device 15 is stopped, the switching valve section moves to the left, and the pressure oil is supplied to the pushing cylinder/device 2 through the pipe 8 and the Nonoirot check valve 55v.
It is sent to the cylinder space on the left side of No. 1, and the cylinder device 4 contracts. Therefore, all the members are displaced backward toward the retracted complete position shown in FIG.

When the deflector 6 begins to rotate from the reversal completion position shown in Fig. 13 to the retraction completion position shown in Fig. 4, the switch L8-1 is closed and the switch L8-1 is opened.
Even if B is disconnected, the self-holding circuit of relay CRI is established through contact CR2''k of relay CR2, which is self-holding. Note that pressure oil is supplied to the left cylinder space of push-in cylinder device 21. At the same time, the upper cylinder space of the vertically moving cylinder device 19 also communicates with the pressure oil source, but since the pressure oil return line force is closed by the cut valve 57, the vertically moving cylinder device 19 does not move. .

When the member reaches the retraction completion position shown in FIG. 4, the retraction completion limit switch L8-5 is pressed by the actuator 33aK and closed, relay CR5 is energized, and its contact CR5'
closes and contact CR5' opens <,! The solenoid 80L5 is energized by the closing of the I point CRY', while the solenoid 80L3 continues to be energized via the relay contact CR3't' since the switch LS-4 is activated and closed. Due to the excitation aK of the solenoid 80L5, the switching valve 57 is switched to the left from the position shown in FIG. 7, the vertically movable cylinder device 19 extends downward due to the hydraulic pressure that continues to act on the cylinder space above the cylinder. It should be noted that since the passage between the pipes is closed by switching the switching valve 57, the pushing cylinder device 21 does not move.

Thus, all the members are displaced from the fully retracted state shown in FIG. 4 to the fully lowered state shown in FIG.

By reaching the lowering completion position shown in FIG.
&Touch the attached lowering completion switch L8-6 [activate it]. Switch L8-6 is actuator 4.
2 closes and energizes relay CR8', which opens relay contact CR8' and closes relay contacts CR8' and CR8''. Therefore, the excitation of solenoid 80L3 and solenoid 80L5 is cut off, and switching valve 57 moves to the right and closes the pipe I, thereby stopping the downward extension of the vertical cylinder device 19, and
Scraping solenoid 80L2 is energized. 9, the switching valve 47 moves to the right from the neutral position, and the pressure oil from the pump 45 is sent into the cylinder space above the scraping cylinder device 15 through the pipe 50t. Therefore, the scraping cylinder device 15 extends downward and the fifth
Scraping is performed from the lowering completed state shown in the figure to the scraping completed state shown in FIG.

When the raking channel 11 reaches the raking completion state shown in FIG. 6, the raking completion limit switch L8-8 is closed by the action of the actuator 401. Therefore, relay CR4 is energized and relay contact CR4' is closed.

At this time, since relay contact CR8'' is closed, the set side 8 of keep relay KRI for rising memory is energized, and keep relay contacts KRI' and KRI' are closed.
When the keep relay contact KRI' closes, the set @S of the push memory keep relay KR2 is energized, the keep relay contact KR2' closes, and the keep relay contact KR2' opens. Since the keep relay contact KR2' closes,
Solenoid 80L4 is energized. on the other hand.

Closed keep relay contact KR2' and closed life-
Solenoid 80L via pre-relay contact KR1't'! i
is excited. In this way, solenoid BOL4゜80
By energizing L5, the switching valve section is switched to the right and the switching valve 57 is switched to the left, so that the pressure oil flows from the I-imp 45 to the lower part of the vertical cylinder device 19 via the switching valve 48.5711. It is fed into the cylinder space, and the cylinder device 19 begins to contract upward at the same time, and all the members begin to move together to the raised state shown in Figure 7.

tJi7 When reaching the rising completion state shown in Fig. 7, actuator C acts on limit switch L8-9 and its contact closes, so relay CR7 is energized, relay contact C87' closes, relay contact CRT' opens, and Relay contact CR
T" is closed. In this case, since relay contact 02" is open, opening and closing of relay contacts CR7' and CR7' has no effect on the operation. KX1 reset 1l
KK input is applied and keep relay ■1 is reset.

Therefore, the keep relay contacts KR1' and KRI' open, and the solenoid FB0L opens by opening the contact KR1'f).
5 excitation is cut off. but.

Even if the upward memory keep relay contact KRI' opens, the push memory keep relay 02 is not reset, so the keep relay contact KR2' remains closed.

Solenoid 5OL4 continues to be energized. For this reason, only the switching valve 57 returns to the position shown in FIG. Pressure oil is sent into the right cylinder space of the device 4 through the switching valve 57', and the pushing cylinder device 4 begins to extend, and deep pushing begins from the completed rising state shown in Fig. 7 to the pushed state shown in Fig. 2. .

Upon completion of deep pushing, all the members reach the positions shown in Figure 2 or Figure II8, and the limit switch LS-1 is closed under the action of the actuator 33a. Therefore, relay CR6 is energized, relay contact CR6'' is closed, and an input is sent to reset 4I4R of push-memory keep relay KR2, resetting keep relay KR2. Therefore, keep relay contact KR2' opens and solenoid 80L
4 is deenergized, and at the same time, contact CR6' forming the self-holding circuit of relay CRI is opened wI, so relay CRI is demagnetized, the entire stroke is completed, and everything stops.

Note that when the dust reaction force acting on the scraping cylinder device 15 exceeds a set value, an unloading action is performed by the relief valve 51, so that an unreasonable force is not applied to the scraping panel LHC.

Assume that in the push-in row @ after the completion of the ascent during the cycle described above, the load caused by the garbage is too large and the push-in speed by the push-in cylinder device 21 becomes slow. In this case, the operator looks at the situation and pushes the individual return I button Rt in the direction of the arrow. Therefore, through circuit 6ov, solenoid 80
L3 is energized and pressure oil enters the push-in cylinder device 21 via the line 54 and the armature check valve 55, causing it to contract, so that the deflector 6 and the push-in A-flank 11 are retracted.

At the same time, the circuit of the 4-talin renoid R80L for controlling the engine of the garbage truck is connected to the power source via the circuit 61'&. This retraction is done when the operator presses his/her hand from the individual return button R (thus stopping it. By pressing the individual return button R, the force is cut off from the power supply. Since the magnetized solenoid 5QL4 is demagnetized before the excitation of the solenoid 80L3 +aVc, switching of the switching valve - is performed without any problem.

When the individual return I button R is released, the circuit ω is cut off, the excitation of the solenoid 80L3 is cut off, and the K1gl path 61 is also cut off at the same time. Next, when push button PI is pressed again, relays CRI and CR2 are energized, and solenoid 5OL4 is activated via keep relay contact KR2', which is closed because the memory of the above-mentioned push memory keep relay KR2 has not been erased. is excited, and the pushing cylinder device 21
is extended again and the pushing is resumed.

Deflector 6 and armpit 11 as described above
The retraction of is until the pushing completion state is reached.
The operator can press the single return button Rt any number of times during the pushing process. As a result, during the pushing process, even under overload, pushing is repeated many times to strongly compress the garbage, and the amount of loaded garbage can be increased.

This is possible because the push-in memory keep relay KR2 stores the push-in stroke regardless of the interruption of the push-in stroke.

When the pushing row *tt is repeated in this way and the pushing is completed, the limit switch L8-1
is closed, relay CR6 is energized, and relay contact CR6''
is closed, the push memory keep relay KR2 is reset, the excitation of the solenoid 80L4 is cut off, and at the same time, the relay C
Since the contact CRY' forming the RI self-holding circuit is opened, the relay CRI is demagnetized and the entire process is completed.

By the way, when the upward stroke is completed, the push-in cylinder device 4 is contracted, so the push-in switch L8-5 is activated by the actuator a3.
aKat,, closed state! There is IIAK. Therefore, relay CR5 is in the energized state and its relay contact CR5
' is open. However, at the moment when the push-in stroke is started after the completion of the upward stroke, the sweet switch L8-5 is released from the actuator 28 and opens, so that the excitation of the relay CR5 is cut off and the relay contact CR5' is closed. At this time, relay contact CRI'' is closed, and relay contact CR6' is also closed because it is not excited because relay CR6 is being pushed in, so when relay contact CR5' is closed, VC is closed at the same time as pushing starts. ), time delay relay TD
R2 is energized. This time delay relay TDR2 opens relay contacts TDR2' and TDR2', and as a result of time-up after energization of time delay relay TDR2, contact TDR2' opens and contact TDR2' closes. Since the contact TDR2' closes, if the pushing is not completed and the relay contact CR6' is closed, the contact C
An input is applied to the reset side of push memory keep relay KR2 via R6' and TDR2't', and the push memory is erased. Therefore.

Set the time it takes for time delay relay TDR2 to time up to be longer than the time from the start of the pushing stroke until the pushing stroke is completed at the normal position (for example, about 3 seconds to 3.5 seconds longer). For example, if the push-in stroke is not completed easily due to overload, the push-in memory of push-in memory key relay KR2 is activated by time delay relay TI.
) is turned off after an appropriate time by the action of R2, completing the cycle. Furthermore, when the time delay relay contact TDR2' opens, the self-holding of the relay CRI disappears, and the cycle returns to the state mK at the start of the cycle.

As mentioned above, in the present invention, if there is a delay in the completion of garbage pushing due to overload, a signal to automatically end the loading cycle is issued after a certain amount of time has elapsed. The overall loading efficiency can be improved.
