Further, a contact piece 41 that restricts the rotation of the link member 33 is fixed to the lower surface of the dust receiving stand 23.
[0018]
In addition, as the cradle 23 rises from the horizontal posture A to the inclined posture B, the side plate 30 is raised from the housing posture D to the protruding posture C, and the trash cradle 23 moves downward from the inclined posture B to the horizontal posture A. Accordingly, interlocking means 50 for lowering the side plate 30 from the projecting posture C to the housing posture D is connected to the driving unit 24. Further, as the garbage stand 23 rises from the horizontal posture A to the inclined posture B, the step between the vehicle stopper 31 and the garbage receptacle 23 is eliminated, and the waste falling from the garbage receptacle 23 in the inclined posture B to the garbage pit 20 is removed.

Note that one or more second connection levers 53 b are provided depending on the size of the garbage receiving base 23. In addition, when a foreign substance such as dust is caught in the gap between the side plate 30 and the garbage receiving base 23 and a load is applied to the first connecting lever 53a when the side plate 30 is raised or lowered, the torque limiter of the main shaft 32 slips. Thus, the driving force of the hydraulic cylinder 34 is prevented from being transmitted to the first connecting lever 53a more than necessary, and the connecting levers 53a and 53b are protected.
[0020]
The dust catching prevention means 51 includes a pair of flaps 54 that are rotatably supported around the horizontal axis 54 a on the garbage receiver 23, a pair of connecting rods 55 having one end rotatably connected to the flap 54, and one end being It consists of a pair of arms 56 which are rotatably connected to the connecting rod 55 and whose other end is fixed to the main shaft 32.

It is possible to move up and down between a state indicated by a chain line) and a storage posture F (a state indicated by a solid line in FIG. 1) in which the upper surface is flush with the loading surface of the garbage receiver 23.
[0021]
Further, in the damping device, as shown in FIG. 6, a cylinder upper limit switch (hereinafter referred to as a cylinder upper limit LS) 60 for detecting when the rod 40 of the hydraulic cylinder 34 is most extended, and the side plate 30 are raised and disposed. Cylinder intermediate limit switch (hereinafter referred to as cylinder intermediate LS) 61 for detecting that the cradle 23 is in the horizontal posture A, and cylinder lower limit switch (hereinafter referred to as cylinder lower limit LS) for detecting when the rod 40 is shortened the most. ) 62, a cradle landing limit switch (hereinafter referred to as a cradle landing LS) 63 for detecting that the loading surface of the garbage cradle 23 and the platform 21 are at the same level, a protruding posture C of the side plate 30 and A side plate upper limit switch (hereinafter referred to as a side plate upper limit LS) 64 that detects the rising posture E of the flap 54, and a side plate 30. Side plate lower limit switch for detecting the retracted position F posture D and flap 54 (hereinafter, referred to as the side plates limit LS) 65 is provided. Then, the switching control of the cylinder solenoid valve is controlled by output signals from the plurality of LSs, the raising / lowering switch for starting the raising / lowering operation of the garbage receiving table 23, and the stopping switch for stopping the raising / lowering operation of the garbage receiving table 23. A control unit is provided for generating an alarm when an abnormality is confirmed or an abnormality is confirmed.
[0022]
In FIGS. 1 and 2, reference numeral 70 denotes an inclined surface that guides the dust that has fallen from the garbage receiving base 23 to the garbage pit 20 when the garbage is thrown in, and 71 in FIG. It is a manhole provided in the garbage receptacle 23 for entering and exiting for performing.
[0023]
In the above-described configuration, the garbage brought to the platform 21 by the vehicle is loaded on the garbage receiving base 23 of the horizontal posture A which is flush with the platform 21, and the non-combustible large-sized garbage or incinerated from the loaded garbage. Select and remove trash that generates toxic gases. At this time, since the side plate 30 is in the accommodation posture D, not only the other end side but also the side end side of the garbage receiving base 23 is open, and the other end side and the side end side of the garbage receiving base 23 are opened. Sorting garbage can be easily taken out from. Thereafter, as shown in FIGS. 6, 7, and 8, the raising switch is turned on to start the raising operation of the garbage receiving table 23 in the horizontal posture A.
[0024]
At this time, first, the on / off state of the cylinder lower limit LS62 in the adjacent damping device is confirmed. This confirms whether or not the adjacent damping device is stopped. If it is off, the adjacent damping device is driven, that is, the garbage receiving base 23 is moving up and down. If there is an operator between the cradle and the garbage receiving base 23 that rises from there, there is a risk that the worker may be caught, so that even if the lift switch is turned on, the upward movement of the garbage receiving base 23 is not performed. It has become. If it is on, the adjacent damping device is stopped, and then it is confirmed whether the cylinder upper limit LS60 is on or off. If it is ON, since the garbage receiving table 23 is fully raised and is in the inclined posture B, the raising operation of the garbage receiving table 23 is not performed. If it is off, the operation of the hydraulic unit is confirmed, the cylinder solenoid valve is in the raised position, and the pressure oil from the hydraulic pump 35 is supplied to the hydraulic cylinder 34. If the hydraulic unit is not operating, a hydraulic unit operation signal is output to prompt the hydraulic unit to operate.
[0025]
When the rod 40 of the hydraulic cylinder 34 begins to extend, as shown in FIG. 1, first, the link member 33 and the main shaft 32 rotate integrally, and when the rod 40 extends to some extent, the link member 33 contacts the contact piece. The rotation of the link member 33 and the main shaft 32 is stopped by coming into contact with 41. With the rotation of the main shaft 32 at this time, the first connecting lever 53a fixed to both ends of the main shaft 32 rises, and the side plate 30 in the housing posture D rises to the protruding posture C. As the side plate 30 moves up, the second connecting lever 53b rises, and the first connecting lever 53a and the second connecting lever 53b support the side plate 30 in the protruding posture C. In addition, as the main shaft 32 rotates, the connecting rod 55 connected to the main shaft 32 via the arm 56 is pushed out, and the flap 54 in the storage posture F rises to a rising posture E.
[0026]
Note that the on / off state of the stop switch is confirmed during this operation, and if the stop switch is on, the cylinder solenoid valve becomes the center position and the ascending operation is stopped. The cylinder intermediate LS61 and the side plate upper limit LS64 are turned on while the side plate 30 and the flap 54 are raised. If the side plate upper limit LS64 is not turned on even if the cylinder intermediate LS61 is turned on, the side plate 30 and the dust Assuming that a foreign object is caught between the cradle 23 and the torque limiter of the main shaft 32 is slipping, an alarm which will be described later is generated, the cylinder solenoid valve is set to the center position, and the ascending operation is stopped.
[0027]
After the link member 33 comes into contact with the contact piece 41, the garbage receiving base 23 rises as the rod 40 extends, and when the rod 40 extends the most, the garbage receiving base 23 is about 50 around the pin 28. The cylinder upper limit LS60 is turned on, the cylinder solenoid valve is in the center position, and the ascending operation is stopped. Then, the garbage loaded on the garbage receiving table 23 slides on the loading surface, falls from the garbage receiving table 23 onto the inclined surface 70, and is guided to the garbage pit 20. At this time, since the upper surface of the flap 54 in the rising posture E is an inclined surface extending from the loading surface of the garbage receiver 23 to the upper surface of the car stopper 31, the step between the car stopper 31 and the garbage receiver 23 is eliminated. Smoothly slides on the loading surface and is caught on the car stop 31 and remains on the garbage receiving base 23.
[0028]
Next, as shown in FIGS. 9 and 10, when the lowering switch is turned on and the lowering operation of the garbage receiving base 23 in the inclined posture B is started, the cylinder lower limit LS62 of the adjacent damping device is first set in the same manner as in the uppering operation. After confirming on / off, the on / off of its own cylinder lower limit LS62 is confirmed. If the cylinder lower limit LS62 is on, the garbage receiving table 23 is fully lowered and assumes the horizontal posture A, and therefore the lowering operation of the garbage receiving table 23 is not performed. If it is off, the operation of the hydraulic unit is confirmed, the cylinder solenoid valve is in the lowered position, and the hydraulic oil is returned from the hydraulic cylinder 34. If the hydraulic unit is not operating, a hydraulic unit operation signal is output to prompt the hydraulic unit to operate.
[0029]
When the rod 40 of the hydraulic cylinder 34 starts to shorten, the garbage receiving base 23 rotates around the pin 28 and descends, the other end of the garbage receiving base 23 comes into contact with the stopper 29, and the garbage receiving base 23 is moved. It becomes a horizontal posture B. When the stop switch is turned on and off during the lowering, and the stop switch is turned on, the cylinder solenoid valve becomes the center position and the lowering operation is stopped. The cylinder intermediate LS61 and the cradle landing LS63 are turned on when the garbage cradle 23 is lowered to the horizontal posture B. Even if the cylinder intermediate LS61 is turned on, the cradle landing is performed. If the LS 63 is not turned on, an alarm is generated assuming that a foreign object is caught between the garbage holder 23 and the stopper 29, and the lowering operation is stopped with the cylinder solenoid valve at the center position.
[0030]
Then, after the dust cradle 23 is in the horizontal posture A, the link member 33 and the main shaft 32 are integrally rotated as the rod 40 is shortened, the link member 33 is separated from the contact piece 41, and the rod 40 The rotation of the link member 33 and the main shaft 32 is stopped when is shortened most. With the rotation of the main shaft 32 at this time, the first connecting lever 53a and the second connecting lever 53b are tilted, and the side plate 30 in the projecting posture C is lowered to the accommodation posture D. Further, the connecting rod 55 connected to the main shaft 32 via the arm 56 is pulled, and the flap 54 in the rising posture E is lowered to the storage posture F. At this time, the cylinder lower limit LS62 and the side plate lower limit LS65 are turned on. However, if the side plate lower limit LS65 is not turned on even if the cylinder lower limit LS62 is turned on, a foreign object is placed between the side plate 30 and the garbage receiving base 23. Is caught and the torque limiter of the main shaft 32 is regarded as slipping, an alarm is generated, and the cylinder solenoid valve becomes the center position to stop the lowering operation.
[0031]
Here, the processing at the time of occurrence of an alarm will be described. As shown in FIG. 11, the alarm is stopped, and only the interlock relating to the landing of the garbage receiving base 23 and the upper and lower limits of the side plate 30 is released. Then, the cause of the alarm is visually examined, and the cause is eliminated by manual operation and manual operation of the damping device. Then, the released interlock is resumed to return to normal operation.
[0032]
In this way, the side plate 30 can be moved up and down between the protruding posture C and the housing posture D, and the side plate 30 is in the housing posture D when the garbage receiving base 23 is in the horizontal posture A. When taking out the sorted garbage from the garbage loaded on the table 23, the side plate is not obstructed as in the prior art, and the sorted garbage is easily taken out from the other end side and the side end side of the garbage receiving table 23. Workability is improved. Moreover, since the side plate 30 protrudes while the garbage receiving table 23 is raised, the garbage does not spill out.
[0033]
Moreover, since the interlocking means 50 which raises / lowers the side plate 30 with the raising / lowering of the garbage receptacle 23 is provided, even if it is a structure which can raise / lower the side plate 30, it is necessary to provide a drive source for exclusive use in order to raise / lower the side plate 30 Therefore, a simple structure with reduced manufacturing cost can be achieved, and trouble such as failure can be reduced by sharing the drive source. Further, the flap 54 can be lifted and lowered by using the same drive source, and the structure is further simplified.
[0034]
Further, since the garbage catching prevention means 51 is provided, when the garbage receiving base 23 is in the inclined posture B, there is no step between the car stopper 31 and the garbage receiving base 23, and the garbage loaded on the garbage receiving base 23 is garbage. The pit 20 can be reliably thrown in, and there is no problem that the garbage is caught on the car stop and remains on the garbage receiving base as in the prior art, and it is not necessary to remove the caught garbage, so that the work efficiency is improved. be able to.
[0035]
In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of the present invention. For example, a drive motor, an electric cylinder, or the like may be employed instead of the hydraulic pump and hydraulic cylinder in the drive unit of the present embodiment. Further, in this embodiment, the side plate and the flap are raised, and then the garbage stand is raised, and after the dust stand is lowered, the side plate and the flap are lowered. May be moved up and down at the same time. Further, instead of eliminating the step between the car stopper and the garbage receiving base by raising the flap, the car stopper may be moved up and down or rotated to eliminate the step between the car stopping and the garbage receiving base.
[0036]
【The invention's effect】
As is apparent from the above description, according to the present invention, the side plate is movable between the protruding posture and the storage posture, and the side plate is in the storage posture when the garbage stand is in the horizontal posture. When removing sorted garbage from the garbage loaded on the cradle, the side plate does not get in the way as in the past, and it is possible to easily remove the sorted garbage from the other end side and side end side of the garbage cradle. It is possible to improve workability.
[0037]
In addition, since interlocking means for moving the side plate with the movement of the garbage cradle is provided, there is no need to provide a dedicated drive source for moving the side plate even if the side plate can be moved. In addition, it is possible to reduce a trouble such as a failure by sharing the drive source.
[0038]
In addition, since a garbage catching prevention means is provided, when the garbage receiver is in an inclined posture, there is no step between the car stopper and the garbage receiver, and the garbage loaded on the garbage receiver is reliably put into the garbage pit. Thus, there is no problem that the garbage is caught on the car stop and remains on the garbage receiving base as in the conventional case, and the work for removing the caught garbage is not required, so that the work efficiency can be improved.
