[0009] [Embodiment 1] In this embodiment, a washing device 100 that washes a compactor vehicle 1 will be described with reference to Figures 1 and 2. Figures 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 Figure 1 and other figures. The front direction is the direction in which the compactor vehicle 1 to be washed is parked relative to the washing device 100. The front-rear direction is the length direction of the compactor vehicle 1, the left-right direction is the width direction of the compactor vehicle 1, and the up-down direction is the height direction of the compactor vehicle 1. 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] In this embodiment, the vehicle to be washed by the washing device 100 is a compactor vehicle 1, but the present invention is not limited to this configuration. The vehicle to be washed by the washing device 100 may be a large vehicle such as a truck or bus, or a specialized vehicle such as a dump truck or compactor vehicle. For example, the compactor vehicle 1 to be washed by the washing device 100 may be a compactor vehicle or truck equipped with a dumpable cargo box or bed.

[0011] As shown in Figures 1 and 2, the compactor truck 1 is equipped with a garbage storage section 2 and a hopper 3. As shown in Figure 2, the garbage storage section 2 has an internal storage space 2A for storing collected garbage. The hopper 3 opens and closes an opening 2B of the garbage storage section 2, which is located at the rear of the compactor truck 1. The closed position 3A of the hopper 3 shown in Figure 1 is the position in which the compactor truck 1 closes the hopper 3. When the hopper 3 is in the closed position 3A, the opening 2B is closed by the hopper 3. The open position 3B of the hopper 3 shown in Figure 2 is the position in which the compactor truck 1 opens the hopper 3. When the hopper 3 is in the open position 3B, the opening 2B is open. As shown in Figure 1, the hopper 3 is provided with an inlet 4 through which garbage is introduced during garbage collection.

[0012] (Overview of cleaning equipment) The cleaning apparatus 100 of this embodiment includes a cleaning unit 10 and a pair of guide rails 20. The cleaning apparatus 100 may further include a supply device 30, a front-rear movement drive unit 40, and a control device 50.

[0013] The cleaning unit 10 extends in the left-right direction and has a plurality of nozzles that spray cleaning liquid. Details of the cleaning unit 10 will be described later. The cleaning unit 10 is attached to a pair of guide rails 20.

[0014] The pair of guide rails 20 extend in the front-rear direction and guide the movement of the cleaning unit 10 in the front-rear direction. The pair of guide rails 20 are supported by a plurality of support columns 21 and are disposed at a distance from the installation surface (ground) on which the cleaning device 100 is installed. The pair of guide rails 20 are disposed so as to be positioned lower than the top surface 2C of the waste container 2 in the vertical direction. The pair of guide rails 20 are also disposed so as to be positioned higher than the inlet 4 of the hopper 3 in the vertical direction. The pair of guide rails 20 are disposed, for example, at a distance of approximately 150 cm from the installation surface.

[0015] The pair of guide rails 20 are arranged so that the compactor 1 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 1. The pair of guide rails 20 extend to a position where they overlap with the compactor 1 when viewed from the side, when the compactor 1 is in the cleaning position. With this configuration, the cleaning unit 10 can be moved to a position where they overlap with the compactor 1 when viewed from the side. Note that it is sufficient that the pair of guide rails 20 extend so as to overlap with the hopper 3 that is positioned in the closed position 3A when viewed from the side, when the compactor 1 is in the cleaning position. Furthermore, the pair of guide rails 20 may be positioned so as not to overlap with the compactor 1 when viewed from the side, when the compactor 1 is in the cleaning position.

[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 that receives instructions from a user.

[0019] (Cleaning unit) Next, the detailed configuration of the cleaning unit 10 will be described with reference to Figs. 3 to 6. Fig. 3 is a side view of the cleaning unit 10. Fig. 4 is a diagram illustrating the relationship between the rotational position of the cleaning unit 10 and the spray direction of each nozzle 16, 17, 18. Fig. 5 is a plan view of the cleaning unit 10 as viewed from above. Fig. 6 is a front view of the cleaning unit 10 as viewed from the front.

[0020] 5 and 6, the cleaning unit 10 has high-pressure nozzles 16, 17 and a low-pressure nozzle 18 that spray cleaning liquid toward the compactor truck 1. The cleaning unit 10 may further have a housing 11. The high-pressure nozzles 16, 17 and the low-pressure nozzle 18 are arranged outside the housing 11. Note that the high-pressure nozzles 16, 17 and the low-pressure nozzle 18 may also be arranged inside the housing 11.

[0021] The high-pressure nozzles 16 and 17 are nozzles that spray high-pressure cleaning liquid. The high-pressure nozzles 16 and 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 respective supply pipes 161 and 171 are connected to the housing 11. The pressurized cleaning liquid for the high-pressure nozzles 16 and 17 passes through a flow path within the housing 11 and is supplied to the respective supply pipes 162 and 172. The high-pressure nozzles 16 and 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 differ from the pressure of the cleaning liquid sprayed by the high-pressure nozzle 17.

[0022] 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 is an angle that determines the spread of the sprayed cleaning liquid in the left-right direction. The high-pressure nozzle 16 is a nozzle capable of narrow-angle spraying, and can spray the cleaning liquid further. The high-pressure nozzle 17 is a nozzle capable of wide-angle spraying, and can spray the cleaning liquid over a wider area. The high-pressure nozzle 17 may also be swiveled left-right. The high-pressure nozzle 16 may also be swiveled left-right.

[0023] 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 port. 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 supply pipe 181 is connected to the housing 11. The cleaning liquid pressurized for the low-pressure nozzle 18 passes through a flow path within the housing 11 and is supplied to the supply pipe 182. The low-pressure nozzle 18 sprays cleaning liquid at 0.25 MPa, for example.

[0024] As shown in FIG. 5 , 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 spaced apart 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 in the left-right direction. 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. That is, 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 outermost nozzles in the left-right direction. That is, the high-pressure nozzle 16 and the high-pressure nozzle 17 are located between the low-pressure nozzles 18 in the left-right direction. The low-pressure nozzle 18 is used to clean gaskets and the like provided at the contact point between the opening 2B of the waste container 2 and the hopper 3.

[0025] By providing high-pressure nozzles 16, 17 suitable for cleaning the inside of the storage space 2A of the garbage storage section 2 and a low-pressure nozzle 18 suitable for cleaning packing and the like provided at the part where the opening 2B of the garbage storage section 2 and the hopper 3 abut, effective cleaning is possible while reducing the possibility of the packing being damaged by the cleaning pressure.

[0026] Furthermore, the high-pressure nozzle 16 and the high-pressure nozzle 17 are located below the cleaning unit 10 in the vertical direction. The high-pressure nozzle 16 and the high-pressure nozzle 17 are located at approximately the same height in the vertical direction. The low-pressure nozzle 18 is located below the cleaning unit 10 in the vertical direction. The low-pressure nozzle 18 is located at a higher position than the high-pressure nozzle 16 and the high-pressure nozzle 17 in the vertical direction.

[0027] The supply pipes 161, 171, and 181 connected to the housing 11 of the cleaning unit 10 may be arranged along a pair of guide rails. The supply pipe 161 and the supply pipe 171 are arranged along the left guide rail 20. The supply pipe 181 and the wiring 13 are arranged along the right guide rail 20. Furthermore, the wiring 13 may be connected to the housing 11. The wiring 13 connects the control device 50 to each device of the cleaning unit 10. The wiring 13 includes wiring for information communication, wiring for supplying power, and the like. The wiring 13 is arranged along the right guide rail 20. By arranging the wiring 13 and the pipes 161, 171, and 181 connected to the cleaning unit 10 along the guide rail 20, safety is improved and the installation surface is easier to clean compared to when they are arranged on the installation surface.

[0028] As shown in FIGS. 3 to 6, the cleaning unit 10 has a rotation axis A1 extending in the left-right direction. Note that, in FIG. 3, the supply pipes 161 and 171 are omitted from illustration for clarity. The cleaning unit 10 is rotatable about the rotation axis A1. Furthermore, the jetting ports of the nozzles 16, 17, and 18 of the cleaning unit 10 are positioned away from the rotation axis A1. The cleaning unit 10 rotates about the rotation axis A1 by a driving force from a rotation drive unit 12. The rotation drive unit 12 is provided near the cleaning unit 10. The rotation drive unit 12 includes a drive motor (not shown). The rotation axis A1 is positioned at the same height as the pair of guide rails 20 in the vertical direction. That is, the rotation axis A1 is positioned so as to overlap the guide rails 20 when viewed from the side.

[0029] (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.

[0030] 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.

[0031] The cleaning unit 10 can rotate to at least -20°. The cleaning unit 10 may also rotate beyond -20° 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 -20°, the nozzles 16, 17, and 18 face forward and downward (diagonally downward). This allows the lower part of the inlet 4 of the hopper 3 and the bottom surface of the storage space 2A of the garbage storage unit 2 to be effectively cleaned.

[0032] 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 hopper 3 located at the open position 3B to be cleaned from the front. This enables effective cleaning of the rear side of the hopper 3.

[0033] The cleaning unit 10 can rotate within a range of, for example, -40° to +165°. The cleaning unit 10 may rotate further in the negative direction from -40° to clean the compactor vehicle 1. The cleaning unit 10 may also rotate further in the positive direction from +165° to clean the compactor vehicle 1.

[0034] (Cleaning method) An example of a method for washing a compactor vehicle 1 using the washing device 100 will be described. The washing device 100 washes the compactor vehicle 1 mainly by dividing the process into the following steps. In the following explanation, the movement of the washing unit 10 in the forward and backward directions and the movement in the rotational direction will be described. In each step, the pressure of the washing liquid sprayed from each nozzle 16, 17, 18, the oscillation of the high-pressure nozzles 16, 17, etc. are set appropriately. Furthermore, the washing method using the washing device 100 is not limited to being performed in the following order.

[0035] When not performing cleaning, the cleaning device 100 positions the cleaning unit 10 in a standby position. The standby position of the cleaning unit 10 is a position where it does not come into contact with any part of the compactor vehicle 1 positioned at the cleaning position. The standby position is, for example, the rearmost position of the cleaning unit 10 in its forward / rearward movement range. After parking the compactor vehicle 1 at the cleaning position, the user cleans the compactor vehicle 1 with the cleaning device 100.

[0036] First, the cleaning device 100 performs a process of cleaning the front side (exterior) of the hopper 3. At this time, the hopper 3 is positioned at the closed position 3A. The control device 50 drives the rotation drive unit 12 to rotate the cleaning unit 10 from the initial position 10A to the first position 10B. The control device 50 drives the supply device 30 to spray cleaning liquid from each of the nozzles 16, 17, and 18. Then, the control device 50 drives the forward / backward movement drive unit 40 to move the cleaning unit 10 forward from the standby position. The control device 50 controls the rotation drive unit 12 to gradually rotate the cleaning unit 10 in the positive rotation direction as it approaches the compactor truck 1. The control device 50 rotates the cleaning unit 10 to the +30° position. In this manner, the entire exterior of the hopper 3 is cleaned.

[0037] Next, the cleaning device 100 performs a process of cleaning the inlet 4 of the hopper 3. The control device 50 controls the forward / backward movement drive unit 40 to move the cleaning unit 10 forward so that the high-pressure nozzles 16, 17 of the cleaning unit 10 are positioned inside or near the inlet 4. Thereafter, the control device 50 controls the rotation drive unit 12 to rotate the cleaning unit 10 in the positive rotation direction and / or the negative rotation direction. In this manner, the inlet 4 is cleaned.

[0038] Next, the cleaning apparatus 100 performs a step of positioning the cleaning unit 10 at the standby position. The control device 50 drives the front-rear movement drive unit 40 to move the cleaning unit 10 backward. When the cleaning unit 10 is positioned at the standby position, the control device 50 stops driving the front-rear movement drive unit 40.

[0039] Next, the cleaning device 100 performs a process of cleaning the back side (inside) of the hopper 3. At this time, the hopper 3 is positioned at the closed position 3A. For example, after the process of positioning the cleaning unit 10 at the standby position, the user positions the hopper 3 at the open position 3B. The control device 50 controls the forward / backward movement drive unit 40 to move the cleaning unit 10 forward from the standby position. The control device 50 moves the cleaning unit 10 to below the hopper 3 at the open position 3B. While moving the cleaning unit 10 forward, the control device 50 drives the rotation drive unit 12 to rotate the cleaning unit 10 in the forward rotation direction. For example, the control device 50 rotates the cleaning unit 10 to near the third position 10D. When the cleaning unit 10 is in the cleaning position below the hopper 3, the control device 50 controls the supply device 30 to spray cleaning liquid from the nozzles 16, 17, and 18. At this time, the control device 50 moves the cleaning unit 10 in the forward and backward directions while moving the cleaning unit 10 in the positive rotation direction and / or the negative rotation direction to clean the back side of the hopper 3. The control device 50 rotates the cleaning unit 10 within a range of +60° to +160°, for example.

[0040] In addition, in the above-mentioned process of cleaning the back side of the hopper 3, the control device 50 may appropriately change the movement range of the cleaning unit 10 in the forward and backward directions and / or the rotation range of the cleaning unit 10 depending on the open state of the hopper 3.

[0041] Next, the cleaning device 100 performs a process of cleaning the storage space 2A of the waste storage unit 2. The control device 50 controls the forward / backward movement drive unit 40 to move the cleaning unit 10 forward to near the opening 2B of the waste storage unit 2. The control device 50 controls the forward / backward movement drive unit 40 so that the cleaning unit 10 is positioned below the hopper 3 in the open position 3B. In this way, the cleaning unit 10 can be moved below the hopper 3 when the hopper 3 is open, thereby effectively cleaning the interior of the storage space 2A. When the cleaning unit 10 is in the cleaning position near the opening 2B, the control device 50 controls the supply device 30 to spray cleaning liquid from the nozzles 16, 17, and 18. At this time, the control device 50 cleans the storage space 2A while moving the cleaning unit 10 in a positive rotation direction and / or a negative rotation direction. The control device 50 rotates the cleaning unit 10, for example, within a range of -40° to +55°. In the process of cleaning the inside of the storage space 2A, the control device 50 may change the rotation range of the cleaning unit 10 as appropriate depending on the degree of inclination of the dust storage section 2.

[0042] Finally, the cleaning apparatus 100 performs a step of positioning the cleaning unit 10 at the standby position. The control device 50 controls the forward / backward movement drive unit 40 to move the cleaning unit 10 backward, and position the cleaning unit 10 at the standby position.

[0043] (Summary of embodiment 1) The washing device 100 according to the first embodiment is a washing device 100 for washing a vehicle, and includes a washing unit 10 that extends along the vehicle width direction and has multiple nozzles 16, 17, and 18 that spray washing liquid along the extension direction, and a pair of guide rails 20 that extend along the vehicle length direction and guide the movement of the washing unit 10. The pair of guide rails 20 are provided so that a vehicle can enter between the guide rails 20, and the washing unit 10 is rotatable around a rotation axis A1 that extends along the vehicle width direction, with the spray ports of the multiple nozzles 16, 17, and 18 positioned away from the rotation axis A1.

[0044] Because the spray nozzles of the nozzles 16, 17, and 18 are positioned away from the rotation axis A1 (off-center), the spray position in the vertical direction can be changed as the cleaning unit 10 rotates without moving the cleaning unit 10 itself in the vertical direction. In addition, the cleaning unit 10 moves in the front-to-rear direction along the guide rails 20 that extend in the vehicle length direction, allowing cleaning at an appropriate distance to suit the shape of the vehicle.

[0045] Specifically, when the vehicle is a compactor truck 1, the compactor truck 1 can be washed at an appropriate distance whether the hopper 3 is open or closed. Therefore, the compactor truck 1 can be washed effectively.

[0046] [Embodiment 2] Another embodiment of the present disclosure will be described below with reference to FIG. 7. FIG. 7 is a side view showing an overview of a cleaning device 100A according to a second embodiment. For ease of explanation, members having the same functions as those described in the above embodiments are denoted by the same reference numerals, and their description will not be repeated. The cleaning device 100A according to the second embodiment differs from the cleaning device 100 according to the first embodiment in that the cleaning unit 10 is supported below the pair of guide rails 20. For ease of explanation, FIG. 7 shows the cleaning unit 10 both in a standby position at the rear and in a position below the hopper 3.

[0047] As shown in FIG. 7, the cleaning device 100A includes a pair of support members 25. The upper ends of the pair of support members 25 are attached to the pair of guide rails 20, respectively, and are movable on the guide rails 20. The height of the pair of guide rails 20 may be such that a person passing under the pair of guide rails 20 is unlikely to collide with the guide rails 20. The pair of guide rails 20 may be higher than the top surface 2C of the waste storage unit 2. When the front-rear movement drive unit 40 is driven, the pair of support members move on the pair of guide rails. As the pair of support members 25 move, the cleaning unit 10 moves in the front-rear direction.

[0048] The cleaning unit 10 is attached to the lower end side of a pair of support members 25. The pair of support members 25 are attached to both the left and right sides of the cleaning unit 10. The cleaning unit 10 is supported by the pair of support members 25 below the pair of guide rails 20. Note that in FIG. 7, for ease of viewing, only the support member 25 attached to the right side of the cleaning unit 10 is shown.

[0049] The cleaning unit 10 of this embodiment is rotatable around a rotation axis A2. The rotation axis A2 of the cleaning unit 10 is provided on the lower end side of the pair of support members 25. The pair of guide rails 20 are provided at a position higher than the rotation axis A2 in the vertical direction. The cleaning unit 10 is disposed so that the rotation axis A2 is approximately 150 cm above the installation surface on which the cleaning device 100A is installed, so that the interior of the compactor truck 1 can be cleaned. By disposing the pair of guide rails 20 at a high position, the possibility of a collision between a person passing under the pair of guide rails 20 can be reduced.
