Description

DETAILED DESCRIPTION OF THE INVENTION The device 1 has a garbage storage box which is open at the rear and has a garbage input box at one end, and the garbage thrown into the input box is movable by the Y1 cylinder inside the input box. Shielding 4~ and anti-qi jh,
J: 1% of garbage collected by pushing it into the storage box +lj
Regarding this, during conventional garbage collection as described in Ruu 1-1, the 11 pressure is switched during the setting pressure), and when it reaches 1, the pressure)) switch is set to 01:
Since it is a system that detects the signal that changes from I' to ON and performs cycle operation, if the shield or reversing oar gets bent during operation, it will stop and then operate. rises, reaches the switching set pressure and reaches the end of the stroke nS
There is a station where the stroke moves to the stroke with stroke 1.Also, change the setting pressure by turning the pressure switch from OFF to ON.
For example, if the viscosity of the hydraulic oil is hard and the cylinder's operating force exceeds the switching setting pressure,
When the cylinder is operating, the pressure is ON from beginning to end during one stroke, and the pressure is ON from beginning to end during one stroke.
The state changing from 01F to ON is Iτ.
At the end of the stroke (even if it is 1Jj- (the end of one row J%), it will end without moving to the next stroke, and the soaking cycle will stop 1-).

The purpose of this is to eliminate the occurrence of pressure fluctuations by setting the minimum and maximum operating times between the actual operating n and f of each stroke in the control circuit, and setting the minimum and maximum operating times within the minimum operating time. The signal that reached 7 pressure + J = (Q F FJ" et al.

Each of the H11 II valves Vl and V2 are electric (I pilot control valves);
19.20 Control valves Vl and V2 are operated by switching the pilot circuit to operate each control valve 1, 21 is a pressure reducing valve, and 22 is a reverse 11-valve, Fig. 6 is a schematic diagram I of the small air circuit, and in this diagram 23 is the control f.
In the i111 circuit, the pressure switch 1 is connected to the terminal of ε.

In addition, the control circuit 23 has a function to start operation when receiving a loading signal, a function to set the load signal to the current stroke, and a function to record the presence or absence of a sound, and the minimum and maximum operation for each stroke. A function to memorize and read the time, a function to receive and receive signals from pressure switches, and a function to not use the signal within the minimum operating time, a function to receive signals from pressure switches etc. , If the signal is between the minimum and maximum operating time, the signal is used as an iE constant signal, and if there is no signal from the pressure switch even after the maximum operating time is reached, the loading function replaces the signal from the pressure switch. Function to create a signal: Upon receiving a normal signal or a loading signal, it has the function of cutting off the excitation signal of the current electric coil and outputting the excitation signal of the ηB and l1lJ coils for the previous stroke. are doing.

1.' of this invention, the direct weight 4 is the above configuration, and the second is 1.
As shown in the figure, the movement shielding plate 5 is raised and is in the state (Koi 7 Garbage input box 3
When the garbage 30 is introduced into one side of the reversing object 8 from the input L129 of the rear i-F section of jl1
Cut to 1 and press the shield (fuse the cylinder 6 with 1 wind and like the 3rd shield, turn the shield il 5, reverse yj8 from 1 to ze, press the jump to the bottom of the input box 3 1-, When the i+J dynamic shield 1M5 reaches the lower limit as shown in 7ir'0), the pressure in the hydraulic circuit reaches the set pressure and the pressure switch 16 or O
N, a signal is sent to the control circuit 23, and when this signal continues for a certain period of time, the electromagnetic coil 517 is energized, the control valve V+ is switched to the scraping side, and the warpage is caused by the cylinder 104 being bent (49J) and reversed (). Turn 18 forward like the 4th hl. When this state is reached, the switch 16, which had been OFF, is turned ON again, and this state continues for a certain period of time, and the electromagnetic coil S2 is energized, and the electric current (I
θ valves 20 and ff (operation) When the control valve v2 is switched to raise III and the shielding plate 5 is raised, the garbage 30 is swept into the garbage storage box 2 as shown in FIG.

When the shielding plate 5 reaches the upper limit in this way, the pressure switch 16 is turned ON again, and when this continues for a certain period of time, the electromagnetic coil SI
8 is energized, the solenoid valve 18 is operated, the control valve ~'1 is switched to the reverse side, and the cylinder 10 is actuated, thereby returning the reversing valve Fj8 to the position indicated by the chain line in FIG. 4 [7 and stopping, The system waits for the next pickling signal.

Although the nL+pressure circuit is omitted, when the upper limit of the j@shielding plate 5 is reached, the extrusion plate cylinder 12 becomes free and the compressed garbage is extruded with a constant pressure tf: 11
I will retire one wheat at a time.

- By repeating the action described above, the Akebono waste introduced from the input port 29 is gradually pushed into the storage box 2, and when the storage box 2 is full, the input (] 29, not shown) is Close the input box 29 with the lid, transport it to the garbage disposal site, open the garbage input box 3 to one side using a hydraulic cylinder or the like around its fulcrum at the top end, extend the cylinder 12, and use the extrusion plate 11 to open the garbage input box 3 to one side. The garbage in the garbage storage box 2 is pushed out from the rear opening.

The malfunction prevention device for the garbage collection vehicle of this invention is as shown in 1-1.
m5 and the reversal cylinder 10 perform 3i11 reversal 4j%, and when the garbage is pushed into the storage box 2 by 8, the pressure switch 16 detects the I and rise of the program in the hydraulic circuit, and the control circuit 231 and the pressure switch 1
6 is ON (after this happens, the duration of the transmission is counted and it is judged whether or not the iUlξ slope 57 reversing plate 8 has operated correctly or not, and then -) it moves to the next step. Because of this, malfunctions such as the shift of the stroke to the end point of the stroke C when the diversion control I E5 or the reversal ILE 8 reaches the end point of the stroke are eliminated. The hydraulic oil is dry and hard. If the cylinder is working at a pressure lower than the set pressure of the pressure switch 16, the pressure switch 16 will be in the ON state throughout the stroke, but in this case, when the maximum operating time is reached, the pressure switch 16 will switch off. Since the loading rod signal added to the signal is used to shift to the next stroke, there is an effect that the loading cycle is prevented from being entrained.
