[0009] [Embodiment 1] An embodiment of the present invention will be described in detail below. First, a washing device 100 for washing a compactor truck 7 in this embodiment will be described with reference to FIGS. 1 and 2. FIGS. 1 and 2 are perspective views showing an overview of the washing device 100. For ease of explanation, the up-down direction, the front-rear direction, and the left-right direction are defined as shown by arrows in FIG. 1 and other figures. The front direction is the direction in which the compactor truck 7 to be washed is parked relative to the washing device 100. The front-rear direction is the length direction of the compactor truck 7, the left-right direction is the width direction of the compactor truck 7, and the up-down direction is the height direction of the compactor truck 7. In this embodiment, the up-down direction is a direction perpendicular to the front-rear direction and the left-right direction, and the front-rear direction is a direction perpendicular to the left-right direction.

[0010] The garbage truck 7 is a so-called garbage collection truck, and is equipped with a storage box 70X and a throw-in box 70Y on its chassis. The storage box 70X is an example of a storage section according to the present disclosure, and the throw-in box 70Y is an example of a throw-in section according to the present disclosure. The rear opening of the storage box 70X is connected to the front opening of the throw-in box 70Y. The top of the throw-in box 70Y is pivotally supported relative to the storage box 70X and can tilt relative to the storage box 70X. The garbage truck 7 cleaned by the cleaning device 100 may be, for example, a press-type garbage truck or a rotary garbage truck. Details of the press-type garbage truck and the rotary garbage truck will be described later.

[0011] (Overview of cleaning equipment) The cleaning device 100 includes a cleaning unit 10 that extends in the left-right direction (vehicle width direction) and has multiple nozzles that spray cleaning liquid along the extension direction. Details of the cleaning unit 10 will be described later. The cleaning unit 10 is rotatable about a rotation axis that extends along the vehicle width direction and is movable in the vehicle length direction. For example, the cleaning unit 10 may be attached to a pair of guide rails 20, as shown in Figures 1 and 2.

[0012] The pair of guide rails 20 extend in the front-rear direction and guide the movement of the washing unit 10 in the front-rear direction. The pair of guide rails 20 are supported by multiple support columns 21 and are disposed at a distance from the installation surface (ground) on which the washing device 100 is installed. The pair of guide rails 20 may be disposed so as to be located lower than the top surface of the storage box 70X in the vertical direction. The pair of guide rails 20 may be disposed, for example, at a distance of approximately 150 cm from the installation surface. When each guide rail 20 has an open surface facing the washing unit 10, a canopy-shaped cover may be provided on the open surface to reduce adhesion of debris scattered during car washing to the rail. The canopy-shaped cover improves the ease of maintenance work, such as applying grease to the chain inside the guide rail 20 or removing debris, compared to providing a cover that closes the open surface.

[0013] The pair of guide rails 20 are provided so that the compactor 7 can enter between them. That is, the distance between the pair of guide rails 20 in the left-right direction is greater than the width of the compactor 7. The pair of guide rails 20 extend to a position where they overlap with the compactor 7 when viewed from the side, when the compactor 7 is in the cleaning position. With this configuration, the cleaning unit 10 can be moved to a position where they overlap with the compactor 7 when viewed from the side. Note that the pair of guide rails 20 only need to extend so as to overlap with the drop box 70Y that is in the closed position (the position in FIG. 1) when viewed from the side, when the compactor 7 is in the cleaning position.

[0014] The configuration for moving the cleaning unit 10 in the vehicle length direction is not limited to the above example. For example, the cleaning unit 10 may be a carriage type that is located in the center of the vehicle width direction and runs on a single rail extending in the vehicle length direction.

[0015] The cleaning device 100 may further include a supply device 30, a front-rear movement drive unit 40, and a control device 50.

[0016] The supply device 30 is a device that supplies the cleaning liquid to be sprayed from the nozzles of the cleaning unit 10. The supply device 30 supplies pressurized cleaning liquid to each nozzle of the cleaning unit 10 via supply piping, which will be described later. The supply device 30 includes, for example, a compressor, a tank, a high-pressure pump unit, etc.

[0017] The front-rear movement drive unit 40 applies a driving force to the cleaning unit 10, moving the cleaning unit 10 in the front-rear direction. The front-rear movement drive unit 40 includes a drive motor (not shown). The drive motor of the front-rear movement drive unit 40 applies a driving force to the cleaning unit 10. The front-rear movement drive unit 40 may be provided inside a connecting member 22 that straddles the pair of guide rails 20.

[0018] The control device 50 controls each component included in the cleaning device 100. The control device 50 is a computer that includes a processor such as a CPU (Central Processing Unit) and executes programs pre-stored in a memory such as a ROM (Read Only Memory) or a RAM (Random Access Memory). The control device 50 is attached to a support 21 that supports the center portion of the right guide rail 20 in the front-rear direction. The control device 50 may include an operation panel 510 that receives instructions from a user.

[0019] The cleaning apparatus 100 may further include a sensor 80. The sensor 80 may be a sensor that determines whether an object is present between an optical element and an optical sensor corresponding to the optical element by determining whether the optical sensor detects electromagnetic waves such as infrared rays emitted from the optical element. The sensor 80 may be attached to the support 21. The provision of the sensor 80 makes it possible to detect if an operator enters the cleaning apparatus 100 while the cleaning apparatus 100 is operating.

[0020] The operation of the sensor 80 may be temporarily suspended while the cleaning device 100 is spraying the cleaning liquid, thereby reducing false detections caused by splashes of the cleaning liquid.

[0021] The cleaning device 100 may further include a sewage tank cleaning device 60. The compactor truck 7 is provided with a sewage tank 75 on the rear side of the vehicle that collects sewage discharged from inside the compactor truck 7. The sewage tank cleaning device 60 is a device equipped with a cleaning nozzle that can spray cleaning liquid toward the side of the compactor truck 7, particularly toward the part corresponding to the sewage tank 75. The sewage tank cleaning device 60 may be attached to a support 21. By providing the sewage tank cleaning device 60, the sewage tank 75, which is easily soiled, can be cleaned.

[0022] The cleaning device 100 may include a water splash prevention panel 90 to reduce water splashing during cleaning. The water splash prevention panel 90 may be attached at any position, such as between the support posts 21 and / or above the guide rails 20, as shown in FIG.

[0023] The washing device 100 may further include a side washing device that can wash the side of the compactor vehicle 7. The side washing device is a device that includes a washing nozzle that can spray washing liquid onto the side of the compactor vehicle 7. The side washing device may be disposed adjacent to the washing device 100 shown in FIG. 1, and both the washing device 100 and the side washing device may use the supply device 30.

[0024] (Cleaning unit) Next, the detailed configuration of the cleaning unit 10 will be described with reference to Figures 3 and 4. Figure 3 is a plan view of the cleaning unit 10 as seen from above. Figure 4 is a diagram showing the cleaning unit 10 rotating.

[0025] 3, the cleaning unit 10 has high-pressure nozzles 16, 17 and a low-pressure nozzle 18 that spray cleaning liquid toward the compactor truck 7. The high-pressure nozzle 16 is an example of a second nozzle according to the present disclosure, and the high-pressure nozzle 17 is an example of a first nozzle according to the present disclosure.

[0026] The high-pressure nozzle 16 and the high-pressure nozzle 17 are nozzles that spray high-pressure cleaning liquid. The high-pressure nozzle 16 and the high-pressure nozzle 17 spray cleaning liquid supplied from the respective supply pipes 162 and 172 from their respective nozzles. The supply device 30 supplies pressurized cleaning liquid for the high-pressure nozzles 16 and 17 to the cleaning unit 10 via the respective supply pipes 161 and 171. The high-pressure nozzle 16 and the high-pressure nozzle 17 spray cleaning liquid at 2 MPa, for example. Note that the pressure of the cleaning liquid sprayed by the high-pressure nozzle 16 may be different from the pressure of the cleaning liquid sprayed by the high-pressure nozzle 17.

[0027] The spray angle W1 of the cleaning liquid from the high-pressure nozzle 16 is narrower than the spray angle W2 of the cleaning liquid from the high-pressure nozzle 17. The spray angle of the cleaning liquid may be an angle that determines the spread of the sprayed cleaning liquid in the vertical direction. The high-pressure nozzle 16 is a nozzle that is capable of narrow-angle spraying, and can spray the cleaning liquid further. The high-pressure nozzle 16 branches into two as shown in Figure 3, and the positions of the tips of each branch when spraying the cleaning liquid may be different in the vertical direction. By having the tips of the two branched nozzles at different heights, even a high-pressure nozzle 16 with a narrow spray angle can expand the spray range in the vertical direction, allowing for efficient car washing. The high-pressure nozzle 16 can be swiveled left and right.

[0028] The high-pressure nozzle 17 is a nozzle capable of wide-angle spraying, and can spray the cleaning liquid over a wider range. In other words, the spray angle W2 of the high-pressure nozzle 17 is wider than the spray angle W1 of the high-pressure nozzle 16. The spray angle W2 of the high-pressure nozzle 17 may be relatively wider than the spray angle W1 of the high-pressure nozzle 16. For example, the high-pressure nozzle 17 may be a nozzle capable of spraying over a wider range in the vertical direction than the high-pressure nozzle 16. Furthermore, the high-pressure nozzle 17 can swing left and right.

[0029] The low-pressure nozzle 18 is a nozzle that sprays cleaning liquid at low pressure. The low-pressure nozzle 18 sprays cleaning liquid supplied from a supply pipe 182 from a spray outlet. The supply device 30 supplies the cleaning liquid pressurized for the low-pressure nozzle 18 to the cleaning unit 10 via a supply pipe 181. The low-pressure nozzle 18 sprays cleaning liquid at 0.25 MPa, for example.

[0030] As shown in FIG. 3 , the cleaning unit 10 has high-pressure nozzles 16, 17 and a low-pressure nozzle 18 arranged in the left-right direction. The high-pressure nozzles 16, 17 and the low-pressure nozzle 18 are arranged at a distance from each other in the left-right direction. In the left-right direction, the high-pressure nozzles 16, 17 are located inside the cleaning unit 10, and the low-pressure nozzle 18 is located outside the cleaning unit 10. More specifically, one high-pressure nozzle 16 is located in the center of the cleaning unit 10 in the left-right direction. The two high-pressure nozzles 17 are located on both sides of the high-pressure nozzle 16 in the left-right direction. In other words, the high-pressure nozzle 16 is located between the high-pressure nozzles 17 in the left-right direction. The two low-pressure nozzles 18 are the nozzles located outermost in the left-right direction, respectively.

[0031] As shown in FIGS. 3 and 4, the cleaning unit 10 has a rotation axis A1 extending in the left-right direction. The cleaning unit 10 is rotatable about the rotation axis A1. The nozzles 16, 17, and 18 of the cleaning unit 10 have their nozzles positioned away from the rotation axis A1. The cleaning unit 10 rotates about the rotation axis A1 by the driving force from the rotation drive unit 12. The rotation axis A1 may be positioned so as to overlap with the guide rail 20 when viewed from the side.

[0032] (Relationship between the rotation position of the cleaning unit and the nozzle spray direction) The relationship between the rotational position of the cleaning unit 10 and the spray direction of each of the nozzles 16, 17, and 18 will be described with reference to Fig. 4. Note that, for ease of viewing, the supply pipe 162 and the supply pipe 172 are omitted from Fig. 4. The spray ports of each of the nozzles 16, 17, and 18 of the cleaning unit 10 are positioned away from the rotation axis A1.

[0033] 4, the initial position 10A of the cleaning unit 10 is indicated by a solid line. The initial position 10A is a position where the multiple nozzles 16, 17, and 18 of the cleaning unit face horizontally (front-to-back). In the present disclosure, the initial position 10A is defined as a rotation angle of the cleaning unit 10 relative to the rotation axis A1 of 0°. The rotation direction of the cleaning unit 10 in which the nozzles face upward from a rotation angle of 0° is defined as a positive (+) rotation angle, and the rotation direction of the cleaning unit 10 in which the nozzles face downward from a rotation angle of 0° is defined as a negative (-) rotation angle.

[0034] The cleaning unit 10 can rotate to at least -10°. The cleaning unit 10 may also rotate beyond -10° in the negative direction. For example, the first position 10B shown by the dashed line in FIG. 4 is a position rotated -40° from the initial position 10A. By rotating the cleaning unit 10 in the negative direction from the initial position 10A to at least -10°, the nozzles 16, 17, and 18 face forward and downward (diagonally downward). This allows the lower portion of the insertion port 74 of the insertion box 70Y and the bottom surface of the storage space 70XA of the storage box 70X to be effectively cleaned.

[0035] The cleaning unit 10 can rotate beyond the second position 10C shown by the dashed line. The second position 10C is a position rotated 90° from the initial position 10A. When the cleaning unit 10 is located at the second position 10C, the nozzles 16, 17, and 18 face vertically upward. The cleaning unit 10 can also rotate to, for example, a third position 10D shown by the dashed line. The third position 10D is a position rotated 120° from the initial position 10A. When the cleaning unit 10 rotates beyond the second position 10C, the nozzles 16, 17, and 18 face rearward and upward (diagonally upward). This allows the rear side of the input box 70Y, which is located in the open position (as shown in FIG. 2), to be cleaned from the front. This enables effective cleaning of the rear side of the input box 70Y.

[0036] The washing unit 10 can rotate within a range of, for example, -40° to +165°. The washing unit 10 may rotate further in the negative direction from -40° to wash the compactor vehicle 7. The washing unit 10 may also rotate further in the positive direction from +165° to wash the compactor vehicle 7.

[0037] <Cleaning method> An example of a method for washing a compactor vehicle 7 using the washing device 100 will be described with reference to Figs. 5 to 9. In the first embodiment, the case where the compactor vehicle 7 to be washed is a press-type compactor vehicle 7A will be described. Fig. 5 is a flowchart showing an example of the washing method according to the first embodiment. Fig. 6 is a diagram showing an example of an operation panel 510 provided in the control device 50. Figs. 7, 8, and 9 are diagrams for explaining each step of the washing method according to the first embodiment. The washing method using the washing device 100 is not limited to the example shown in Fig. 5, and may include other steps.

[0038] (Reception process) First, in the reception process of step S12, the washing device 100 receives instructions regarding the washing of the compactor vehicle 7. In the reception process, when the worker parks the compactor vehicle 7 at the washing position, the worker inputs instructions regarding the washing of the compactor vehicle 7 via the operation panel 510. For example, as shown in FIG. 6, area 501 of the operation panel has a course selection button for selecting a car wash course, and the operator can select a course such as "water wash" and a washing speed such as "speed wash" or "thorough wash." Based on the input via the selection button, the washing device 100 performs the washing operation according to the selected course. For example, "speed wash" may be a wash with a shortened washing time, while "thorough wash" may be a thorough wash with an extended washing time. If "speed wash" is selected, the washing device 100 may shorten the washing time by increasing the swing speed of the washing unit 10, for example. The selection of "speed wash" or "thorough wash" may be determined by the operator, taking into account the degree of dirt on the vehicle, etc.

[0039] Area 502 has vehicle type selection buttons for selecting the characteristics of the compactor vehicle 7, such as the type and size. The vehicle type selection buttons allow the selection of, for example, whether the compaction type is press type or rotary type, whether the discharge type is push type or dump type, and the size of the compactor vehicle 7. When washing a press type compactor vehicle 7A, the worker selects the press type as the compression type in the reception process. The vehicle type selection buttons allow the input of information regarding the external characteristics of the compactor vehicle 7, so the washing device 100 can perform a car wash according to those characteristics.

[0040] Area 503 shows, including illustrations, the operation of the compactor vehicle 7 in each cleaning step. By showing the operation procedure including illustrations, it is possible to assist the operator in the operation.

[0041] A start button for starting the cleaning operation and a stop button for stopping the cleaning operation are arranged in area 504. The cleaning device 100 can start or stop the cleaning operation by inputting via the start button or stop button.

[0042] Area 505 may contain detailed instructions on how to operate the device, precautions, and the like.

[0043] (1st step) In the first step (step S13), the cleaning device 100 cleans the outside of the loading mechanism.

[0044] The structure of the press-type packer vehicle 7A will now be described with reference to FIG. 7. A trash inlet 74, an opening for trash insertion, is located at the rear of the trash box 70Y of the press-type packer vehicle 7A. A sliding door 73 is configured to open and close the trash inlet 74. The trash box 70Y is also equipped with a loading mechanism 71A for loading trash inserted through the inlet 74 into a storage box 70X. The loading mechanism 71A includes a sliding plate 711 and a compression plate 712 supported at the lower end of the sliding plate 711 so as to be swingable back and forth. The sliding plate 711 extends across the entire width of the trash box 70Y and is tilted from the upper front to the lower rear, sliding along the inclined direction. By appropriately controlling the sliding motion of the sliding plate 711 and the swinging motion of the compression plate 712, trash inserted through the inlet 74 is stored in the storage box 70X.

[0045] In the first step, the worker operates the press-type packer vehicle 7A in accordance with the display on the operation panel 510 to open the opening / closing door 73 of the drop box 70Y. The worker also lowers the tip of the loading mechanism 71A to the inner bottom 72 of the drop box 70Y. In the case of the press-type packer vehicle 7A, the tip of the loading mechanism 71A means the tip of the compression plate 712. After the worker confirms that the press-type packer vehicle 7A is in the state shown in FIG. 7, with the opening / closing door 73 in the open state and the tip of the loading mechanism 71A lowered to the inner bottom 72, he presses the start button on the operation panel 510 to begin the first step of cleaning.

[0046] The cleaning device 100 performs the first cleaning operation when an operator presses a start button to input a work start instruction.

[0047] When the cleaning device 100 is not performing cleaning, the cleaning unit 10 is positioned in a standby position. The standby position of the cleaning unit 10 is a position where the cleaning unit 10 does not come into contact with any part of the compactor vehicle 7 positioned in the cleaning position. The standby position is, for example, the rearmost position of the cleaning unit 10 in its longitudinal movement range.

[0048] When the start button is pressed, the cleaning device 100 moves the cleaning unit 10 forward so that the high-pressure nozzles 16, 17 of the cleaning unit 10 are positioned near the inlet 74. At this time, the cleaning unit 10 may be moved forward with the tips of the high-pressure nozzles 16, 17 pivoted to either the left or right (pointing diagonally relative to the vehicle length direction) rather than facing forward. Furthermore, the cleaning unit 10 may be moved forward in a state where it has rotated to the first position 10B shown in FIG. 4. This further reduces the possibility of accidental contact between the high-pressure nozzles 16, 17 and workers, etc.

[0049] When the cleaning unit 10 has finished moving forward, the cleaning device 100 sprays cleaning liquid from the rear of the vehicle to clean the exterior surface of the loading mechanism 71A, as shown in FIG. 7 . First, the high-pressure nozzle 17, capable of wide-angle spraying, may be used to spray cleaning liquid from top to bottom while swinging left and right to clean the entire exterior surface of the loading mechanism 71 (full-body cleaning process). This full-body cleaning process may also clean the lower part of the loading opening 74, along with the exterior surface of the loading mechanism 71. Then, the high-pressure nozzle 16, capable of narrow-angle spraying, may be used to locally clean the moving parts of the loading mechanism 71A while swinging left and right (local cleaning process). The moving parts of the loading mechanism 71A may be, for example, the connecting portion between the sliding plate 711 and the compression plate 712. By including the full-body cleaning process and the local cleaning process of cleaning the moving parts where dirt tends to accumulate in the first process, the exterior surface of the loading mechanism 71A can be cleaned more accurately.

[0050] When the first step of the cleaning operation is completed, the cleaning device 100 may move the cleaning unit 10 back to the standby position and temporarily stop the operation.

[0051] (2nd process) In the subsequent second step (step S14), the cleaning device 100 cleans the inside of the loading mechanism.

[0052] In the second step, the operator closes the door 73 of the drop box 70Y according to the display on the operation panel 510. The operator also flips up (rotates) the drop box 70Y until it is in a substantially horizontal position as shown in FIG. 8. When flipping up the drop box 70Y to a substantially horizontal position, it may be difficult to confirm from the driver's seat whether the drop box 70Y is in a horizontal position. To assist the operator in flipping up the drop box 70Y to a horizontal position, the cleaning device 100 may be equipped with a curved mirror with a horizontal line in a location that is easily visible from the driver's seat. After the operator confirms that the door 73 of the press-type packer vehicle 7A is in a closed position and the drop box 70Y is in a substantially horizontal position as shown in FIG. 8, the operator presses the start button on the operation panel 510 to begin the second cleaning step.

[0053] The cleaning device 100 performs the second cleaning step when an operator presses a start button to input a work start command. Alternatively, the cleaning device 100 may further include a sensor that can detect the position of the input box 70Y. In this case, the cleaning device 100 may start the second cleaning step when the sensor detects that the input box 70Y has reached a horizontal position.

[0054] When the second cleaning step begins, the cleaning device 100 moves the cleaning unit 10 forward until the cleaning unit 10 is positioned below the drop box 70Y, which is located forward of the rear end of the press-type packer vehicle 7A and in a horizontal position.

[0055] When the cleaning unit 10 has finished moving forward, the cleaning device 100 sprays cleaning liquid from below the drop box 70Y to clean the inner surface of the loading mechanism 71A, as shown in Fig. 8. At this time, the high-pressure nozzle 17 may be used to clean the entire inner surface of the loading mechanism 71A by combining the rotation of the cleaning unit 10 with the swinging motion of the high-pressure nozzle 17. By using the high-pressure nozzle 17 capable of spraying at a wide angle, the entire inner surface of the loading mechanism 71A can be efficiently cleaned.

[0056] When the second step of the cleaning operation is completed, the cleaning device 100 may temporarily stop operation.

[0057] (Additional process) In the subsequent additional step (step S15), the cleaning device 100 cleans the inner bottom of the throw-in box 70Y.

[0058] In the additional process, the operator follows the display on the operation panel 510 to position the tip of the compression plate 712 at the lower end 74B of the inlet. This allows the entire inner bottom 72 to be cleaned by spraying cleaning liquid from below. The operator also raises the inlet box 70Y to a position higher than the horizontal position shown in Figure 9. After confirming that the press-type packer vehicle 7A is in the position shown in Figure 9, the operator presses the start button on the operation panel 510 to begin the cleaning in the additional process.

[0059] The cleaning apparatus 100 starts the cleaning operation of the additional process when the operator presses the start button to input a work start instruction.

[0060] When the additional cleaning step begins, the cleaning device 100 sprays cleaning liquid onto the inner bottom 72 of the input box 70Y from below to clean the inner bottom 72. At this time, the high-pressure nozzle 16 is used to clean the entire inner bottom 72 by combining the rotation of the cleaning unit 10 and the swinging motion of the high-pressure nozzle 16. By flipping the input box 70Y above the horizontal position, the inner bottom 72 is at an angle that makes it easier to clean, but it also increases the distance from the nozzle. Because the high-pressure nozzle 16 is capable of spraying long distances, using the high-pressure nozzle 16 in the additional step allows for good cleaning of the inner bottom 72.

[0061] When the cleaning operation of the additional step is completed, the cleaning apparatus 100 may start the cleaning of the third step consecutively.

[0062] (3rd step) In the third step, the cleaning device 100 cleans the inside of the container box 70X.

[0063] In the third step, the cleaning device 100 sprays cleaning liquid from the rear of the storage box 70X to clean the inside of the storage box 70X. At this time, the high-pressure nozzle 17 may be used to clean the inside of the storage box 70X by combining the rotational movement of the cleaning unit 10 and the oscillating movement of the high-pressure nozzle 17. Furthermore, the cleaning device 100 may spray cleaning liquid from the low-pressure nozzle 18 to clean a gasket or the like provided at the portion where the opening of the storage box 70X and the throwing box 70Y come into contact.

[0064] By using a high-pressure nozzle 17 suitable for cleaning the inside of the storage box 70X and a low-pressure nozzle 18 suitable for cleaning packings and the like, effective cleaning is possible while reducing the possibility of the packings being damaged by the cleaning pressure.

[0065] (Water removal process) After the series of cleaning operations is completed, the cleaning device 100 may perform a water draining process to drain water remaining in the high-pressure nozzles 16, 17 and the low-pressure nozzle 18. The water draining process may be performed by supplying air to each nozzle. At this time, the nozzles may be oriented forward to prevent water from splashing, or may be oriented in any direction depending on the installation location of the cleaning device 100. Alternatively, the water draining process may be performed while swinging each nozzle.

[0066] When the cleaning device 100 performs the next cleaning after the water removal step, it takes a certain amount of time until the cleaning liquid is sprayed because air remains in the nozzle. Therefore, even if cleaning is performed by the high-pressure nozzle 16 after cleaning by the high-pressure nozzle 17 in the first step of the next cleaning, the spraying of the cleaning liquid from the high-pressure nozzle 16 may start simultaneously with the spraying of the high-pressure nozzle 17. This eliminates the wait time for the spraying of the cleaning liquid from the high-pressure nozzle 16, thereby shortening the cleaning time.

[0067] [Embodiment 2] Another embodiment of the present invention will be described below with reference to Figures 10 and 11. Figures 10 and 11 are diagrams for explaining each step of a cleaning method according to embodiment 2. For ease of explanation, members having the same functions as those described in the above embodiment are denoted by the same reference numerals, and their description will not be repeated.

[0068] In the second embodiment, a case will be described in which the packer vehicle 7 to be cleaned is a rotary packer vehicle 7B. The method for cleaning the rotary packer vehicle 7B using the cleaning device 100 can omit the additional process of the press-type packer vehicle 7A described in the first embodiment. The following description will particularly focus on the differences from the first embodiment.

[0069] The structure of the rotary packer vehicle 7B will now be described with reference to FIG. 10. An inlet 74, which is an opening for inserting garbage, is located at the rear of the dump box 70Y of the rotary packer vehicle 7B. A sliding door 73 is configured to open and close the inlet 74. The dump box 70Y is also equipped with a loading mechanism 71B for loading garbage inserted through the inlet 74 into the storage box 70X. The loading mechanism 71B includes a pusher plate 713 and a lifter plate 714 positioned below the pusher plate 713. The lifter plate 714 rotates around an axis extending in the width direction of the vehicle, thereby lifting garbage inserted through the inlet 74 along the inner bottom 72 of the dump box 70Y to the position of the pusher plate 713. The pusher plate 713 then pushes the garbage lifted by the rotation of the pusher plate 713 into the storage box 70X.

[0070] (Reception process) The reception process is generally the same as in embodiment 1. When cleaning the rotary packer vehicle 7B, the worker selects the rotary type as the compression type in the reception process.

[0071] (1st step) When cleaning the rotary packer vehicle 7B, in the first step, the operator opens the opening / closing door 73 of the drop box 70Y according to the display on the operation panel 510. The operator also lowers the tip of the loading mechanism 71B to the inner bottom 72 of the drop box 70Y. In the case of the rotary packer vehicle 7B, the tip of the loading mechanism 71A means the tip of the lifting plate 714. The operator positions the loading mechanism 71B so that the inclination angles of the pushing plate 713 and the lifting plate 714 are approximately the same, or so that the tip of the lifting plate 714 is positioned near the lowest point of the inner bottom 72. After confirming that the opening / closing door 73 of the rotary packer vehicle 7B is open and the tip of the loading mechanism 71A is lowered to the inner bottom 72 as shown in FIG. 10, the operator presses the start button on the operation panel 510 to begin the first step of cleaning.

[0072] When the start button is pressed, the cleaning device 100 performs the cleaning operation of the first step in the same manner as the procedure described in the first step of the first embodiment.

[0073] (2nd process) When washing the rotary packer vehicle 7B, in the second step, the worker closes the opening and closing door 73 of the drop box 70Y in accordance with the display on the operation panel 510. The worker also positions the tip of the lifting plate 714 at the lower end 74B of the drop opening. Furthermore, the worker flips up (rotates) the drop box 70Y so that the drop box 70Y is in a substantially horizontal position as shown in FIG.

[0074] After the operator confirms that the rotary packer vehicle 7B is in the state shown in FIG. 11, he presses the start button on the operation panel 510 to start the second cleaning step.

[0075] When the start button is pressed, the cleaning device 100 performs the cleaning operation of the second step in the same manner as described in the second step of the first embodiment.

[0076] If the rotation type is selected in the receiving step, the cleaning device 100 may further perform an inner bottom cleaning step. In the inner bottom cleaning step, the cleaning device 100 may use the high-pressure nozzle 16 to clean the inner bottom 72 of the drop box 70Y while combining the rotational movement of the cleaning unit 10 and the swinging movement of the high-pressure nozzle 16. By also cleaning the inner bottom 72 in the second step, the inner surface and inner bottom 72 of the drop box 70Y can be efficiently cleaned.

[0077] (Third process: draining process) The third step and the water-removing step can be carried out in the same manner as in the first embodiment.
