[Figure 2] This is a perspective view showing an overview of the cleaning device according to Embodiment 1 of this disclosure. [Figure 3] This is a side view of the cleaning unit, seen from the side. [Figure 4] This diagram illustrates the relationship between the rotational position of the cleaning unit and the spray direction of the nozzle. [Figure 5] This is a plan view of the cleaning unit from above. [Figure 6] This is a front view of the cleaning unit, seen from the front. [Figure 7] This is a side view showing an overview of the cleaning apparatus according to Embodiment 2 of this disclosure. [Modes for carrying out the invention]

[0009] [Embodiment 1] In this embodiment, the cleaning device 100 for cleaning the packer truck 1 will be described with reference to Figures 1 and 2. Figures 1 and 2 are perspective views showing an overview of the cleaning device 100. For convenience of explanation, the vertical direction, the front-rear direction, and the left-right direction are defined as indicated by the arrows in Figure 1, etc. The front direction is the direction in which the packer truck 1 to be cleaned is parked relative to the cleaning device 100. The front-rear direction is the vehicle length direction of the packer truck 1, the left-right direction is the vehicle width direction of the packer truck 1, and the vertical direction is the vehicle height direction of the packer truck 1. In this embodiment, the vertical direction is perpendicular to the front-rear direction and the left-right direction, and the front-rear direction is perpendicular to the left-right direction.

[0010] In this embodiment, the example shown is when the vehicle cleaned by the cleaning device 100 is a garbage truck 1, but the configuration is not limited to this. The vehicle cleaned by the cleaning device 100 may be a large vehicle such as a truck or bus, or a special vehicle such as a dump truck or garbage truck. For example, the garbage truck 1 cleaned by the cleaning device 100 may be a garbage truck or truck equipped with a dumpable cargo box or cargo bed.

[0011] As shown in Figures 1 and 2, the garbage 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 a storage space 2A inside for storing collected garbage. The hopper 3 opens and closes the opening 2B of the garbage storage section 2, which is located at the rear of the garbage truck 1. The closed position 3A of the hopper 3 shown in Figure 1 is the position when the garbage truck 1 has closed 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 when the garbage truck 1 has opened 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 input port 4 for loading garbage during garbage collection.

[0012] (Overview of the cleaning equipment) The cleaning device 100 of this embodiment comprises a cleaning unit 10 and a pair of guide rails 20. The cleaning device 100 may further comprise a supply device 30, a forward / backward movement drive unit 40, and a control device 50.

[0013] The cleaning unit 10 extends along the left-right direction and has multiple nozzles for spraying cleaning fluid. Details of the cleaning unit 10 will be described later. The cleaning unit 10 is mounted on a pair of guide rails 20.

[0014] A pair of guide rails 20 extend along 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 a plurality of support columns 21 and are positioned at a distance from the installation surface (ground) on which the washing device 100 is installed. In the vertical direction, the pair of guide rails 20 are positioned below the top surface 2C of the waste collection section 2. Also, in the vertical direction, the pair of guide rails 20 are positioned above the inlet 4 of the hopper 3. The pair of guide rails 20 are positioned, for example, at a distance of approximately 150 cm from the installation surface.

[0015] The pair of guide rails 20 are provided so that the packer truck 1 can enter between the guide rails 20. That is, the distance between the pair of guide rails 20 in the left-right direction is greater than the width of the packer truck 1. The pair of guide rails 20 extend to a position that overlaps with the packer truck 1 when viewed from the side, when the packer truck 1 is in the washing position. With this configuration, the washing unit 10 can be moved to a position that overlaps with the packer truck 1 when viewed from the side. The pair of guide rails 20 only needs to extend so that it overlaps with the hopper 3, which is in the closed position 3A, when the packer truck 1 is in the washing position, when viewed from the side. Alternatively, the pair of guide rails 20 may be in a position that does not overlap with the packer truck 1 when the packer truck 1 is in the washing position, when viewed from the side.

[0016] The supply device 30 is a device that supplies cleaning fluid sprayed from the nozzles of the cleaning unit 10. The supply device 30 supplies pressurized cleaning fluid 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 forward and backward movement drive unit 40 applies a driving force to the cleaning unit 10 and moves the cleaning unit 10 in the forward and backward directions. The forward and backward movement drive unit 40 includes a drive motor not shown in the figure. The drive motor of the forward and backward movement drive unit 40 applies a driving force to the cleaning unit 10. The forward and backward movement drive unit 40 may be provided inside a connecting member 22 straddling between a pair of guide rails 20.

[0018] The control device 50 controls each part included in the cleaning device 100. The control device 50 is, for example, a computer including a processor such as a CPU (Central Processing Unit) and executing a program stored in advance in a memory such as a ROM (Read Only Memory) and a RAM (Random Access Memory). The control device 50 is attached to a support column 21 that supports the central portion in the front and back directions of the right guide rail 20. The control device 50 may include an operation panel for receiving instructions from the user.

[0019] (Cleaning unit) Next, a 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 as viewed from the side. FIG. 4 is a diagram for explaining the relationship between the rotational position of the cleaning unit 10 and the injection directions of the nozzles 16, 17, and 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] As shown in FIGS. 5 and 6, the cleaning unit 10 has high-pressure nozzles 16, 17 and a low-pressure nozzle 18 that inject cleaning liquid toward the packer vehicle 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 be arranged inside the housing 11.

[0021] The high-pressure nozzles 16 and 17 are nozzles that spray cleaning fluid at high pressure. The high-pressure nozzles 16 and 17 spray cleaning fluid supplied from their respective supply pipes 162 and 172 from their respective nozzles. The supply device 30 supplies the pressurized cleaning fluid 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 fluid for the high-pressure nozzles 16 and 17 passes through the flow path inside the housing 11 and is supplied to the respective supply pipes 162 and 172. As an example, the high-pressure nozzles 16 and 17 spray cleaning fluid at 2 MPa. Note that the pressure of the cleaning fluid sprayed by high-pressure nozzle 16 and the pressure of the cleaning fluid sprayed by high-pressure nozzle 17 may be different.

[0022] The spray angle W1 of the cleaning fluid from the high-pressure nozzle 16 is narrower than the spray angle W2 of the cleaning fluid from the high-pressure nozzle 17. The spray angle of the cleaning fluid is the angle that defines the spread of the sprayed cleaning fluid in the left-right direction. The high-pressure nozzle 16 is a nozzle capable of narrow-angle spraying, and can spray the cleaning fluid to a greater distance. The high-pressure nozzle 17 is a nozzle capable of wide-angle spraying, and can spray the cleaning fluid over a wider area. The high-pressure nozzle 17 may also be able to swivel in the left-right direction. The high-pressure nozzle 16 may also be able to swivel in the left-right direction.

[0023] The low-pressure nozzle 18 is a nozzle that sprays cleaning fluid at a low pressure. The low-pressure nozzle 18 sprays cleaning fluid supplied from the supply pipe 182 through its nozzle. The supply device 30 supplies pressurized cleaning fluid for the low-pressure nozzle 18 to the cleaning unit 10 via the supply pipe 181. The supply pipe 181 is connected to the housing 11. The pressurized cleaning fluid for the low-pressure nozzle 18 passes through a flow path inside the housing 11 and is supplied to the supply pipe 182. As an example, the low-pressure nozzle 18 sprays cleaning fluid at 0.25 MPa.

[0024] As shown in Figure 5, the cleaning unit 10 has high-pressure nozzles 16, 17 and low-pressure nozzles 18 along the left-right direction. The high-pressure nozzles 16, 17 and low-pressure nozzles 18 are spaced apart 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 nozzles 18 are 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 either side of the high-pressure nozzle 16 in the left-right direction. That is, in the left-right direction, the high-pressure nozzle 16 is located between the high-pressure nozzles 17. The two low-pressure nozzles 18 are the outermost nozzles in the left-right direction. That is, in the left-right direction, the high-pressure nozzles 16 and 17 are located between the low-pressure nozzles 18. The low-pressure nozzles 18 are used to clean packing and other parts provided in the area where the opening 2B of the waste collection section 2 and the hopper 3 come into contact.

[0025] By providing high-pressure nozzles 16 and 17 suitable for cleaning the storage space 2A of the waste storage section 2, and a low-pressure nozzle 18 suitable for cleaning packing and other parts provided at the point where the opening 2B of the waste storage section 2 and the hopper 3 come into contact, 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 high-pressure nozzle 17 are located below the cleaning unit 10 in the vertical direction. The high-pressure nozzle 16 and 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 high-pressure nozzle 17 in the vertical direction.

[0027] Each of 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. Supply pipes 161 and 171 are arranged along the left-side guide rail 20. Supply pipe 181 and wiring 13 are arranged along the right-side guide rail 20. In addition, wiring 13 may be connected to the housing 11. Wiring 13 is wiring that connects the control device 50 to each device of the cleaning unit 10. Wiring 13 includes wiring for information communication, wiring for power supply, etc. Wiring 13 is arranged along the right-side guide rail 20. By arranging the wiring 13 and pipes 161, 171, and 181 connected to the cleaning unit 10 along the guide rails 20, safety is improved compared to when they are arranged on the installation surface, and cleaning of the installation surface is also made easier.

[0028] As shown in Figures 3 to 6, the cleaning unit 10 has a rotating shaft A1 that extends along the left-right direction. Note that in Figure 3, the supply pipes 161 and 171 are omitted from the illustration for clarity. The cleaning unit 10 is rotatable around the rotating shaft A1. The nozzles 16, 17, and 18 of the cleaning unit 10 are located away from the rotating shaft A1. The cleaning unit 10 rotates around the rotating shaft A1 by a driving force from the rotary drive unit 12. The rotary drive unit 12 is located near the cleaning unit 10. The rotary drive unit 12 is equipped with a drive motor (not shown). In the vertical direction, the rotating shaft A1 is at the same height as the pair of guide rails 20. That is, when viewed from the side, the rotating shaft A1 is located in a position that overlaps with the guide rails 20.

[0029] (Relationship between the rotational position of the cleaning unit and the spray direction of the nozzle) Referring to Figure 4, the relationship between the rotational position of the cleaning unit 10 and the spray direction of each nozzle 16, 17, and 18 will be explained. Note that in Figure 4, supply pipes 162 and 172 have been omitted for clarity. Also, the spray ports of each nozzle 16, 17, and 18 of the cleaning unit 10 are located away from the rotation axis A1.

[0030] In Figure 4, the initial position 10A of the cleaning unit 10 is shown by a solid line. The initial position 10A is the position where the multiple nozzles 16, 17, and 18 of the cleaning unit are facing horizontally (front-to-back direction). In this disclosure, the initial position 10A is assumed to be when the rotation angle of the cleaning unit 10 with respect to the rotation axis A1 is 0°. Furthermore, the rotation direction of the cleaning unit 10 in which the nozzles point upward from a rotation angle of 0° is defined as positive (+) rotation angle, and the rotation direction of the cleaning unit 10 in which the nozzles point downward from a rotation angle of 0° is defined as negative (-) rotation angle.

[0031] The cleaning unit 10 can rotate to at least -20°. The cleaning unit 10 may rotate further in the negative direction beyond -20°. For example, the first position 10B shown by the dashed line in Figure 4 is a position rotated -40° from the initial position 10A. By rotating the cleaning unit 10 in the negative direction to at least -20° from the initial position 10A, each nozzle 16, 17, and 18 faces forward and downward (diagonally downward). This allows for effective cleaning of the lower part of the inlet 4 of the hopper 3 and the bottom surface of the storage space 2A of the waste storage section 2.

[0032] The cleaning unit 10 can rotate beyond the second position 10C, indicated by the dashed line. The second position 10C is rotated +90° from the initial position 10A. When the cleaning unit 10 is in the second position 10C, each nozzle 16, 17, and 18 faces vertically upward. The cleaning unit 10 can rotate, for example, to the third position 10D, indicated by the dashed line. The third position 10D is rotated +120° from the initial position 10A. When the cleaning unit 10 rotates beyond the second position 10C, each nozzle 16, 17, and 18 faces backward and upward (diagonally upward). Therefore, the back side of the hopper 3, which is in the open position 3B, can be cleaned from the front. This enables effective cleaning of the back side of the hopper 3.

[0033] The cleaning unit 10 is rotatable, for example, within a range of -40° to +165°. The cleaning unit 10 may also rotate in a negative direction beyond -40° to clean the packer truck 1. Alternatively, the cleaning unit 10 may rotate in a positive direction beyond +165° to clean the packer truck 1.

[0034] (Cleaning method) An example of a cleaning method for a garbage truck 1 using the cleaning device 100 is described below. The cleaning device 100 cleans the garbage truck 1 mainly in the following steps. In the following description, the forward and backward movement and rotational movement of the cleaning unit 10 will be described. The pressure of the cleaning liquid sprayed from each nozzle 16, 17, and 18, the oscillation of the high-pressure nozzles 16 and 17, etc., in each step will be set as appropriate. Furthermore, the cleaning method by the cleaning 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 packer truck 1 located at the cleaning position. The standby position is, for example, the position where the cleaning unit 10 has moved furthest back within its range of movement in the front-rear direction. After the user parks the packer truck 1 at the cleaning position, the cleaning device 100 performs cleaning on the packer truck 1.

[0036] First, the cleaning device 100 performs the process of cleaning the front (exterior) side of the hopper 3. At this time, the hopper 3 is positioned in the closed position 3A. The control device 50 drives the rotary 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 fluid from each nozzle 16, 17, and 18. After that, 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 rotary drive unit 12 to gradually rotate the cleaning unit 10 in the positive rotation direction as it approaches the packer truck 1. The control device 50 rotates the cleaning unit 10 to a position of +30°. In this way, the entire exterior of the hopper 3 is cleaned.

[0037] Next, the cleaning device 100 performs the process of cleaning the inlet 4 of the hopper 3. The control device 50 controls the forward and backward movement drive unit 40 to move the cleaning unit 10 forward so that the high-pressure nozzles 16 and 17 of the cleaning unit 10 are located inside or near the inlet 4. Then, 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 way, the inlet 4 is cleaned.

[0038] Next, the cleaning device 100 performs the step of positioning the cleaning unit 10 in a standby position. The control device 50 drives the forward / backward movement drive unit 40 to move the cleaning unit 10 backward. When the cleaning unit 10 is in the standby position, the control device 50 stops driving the forward / backward movement drive unit 40.

[0039] Next, the cleaning device 100 performs a step of cleaning the back (inside) of the hopper 3. At this time, the hopper 3 is positioned in the closed position 3A. For example, after the cleaning unit 10 is positioned in the standby position, the user positions the hopper 3 in 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 in 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 positive rotational direction. For example, the control device 50 rotates the cleaning unit 10 to the vicinity of 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 each nozzle 16, 17, 18. At this time, the control device 50 moves the cleaning unit 10 in the forward and backward directions, and while moving the cleaning unit 10 in the positive rotation direction and / or the negative rotation direction, it cleans the back side of the hopper 3. The control device 50 rotates the cleaning unit 10 in a range of, for example, +60° to +160°.

[0040] In addition, during the process of cleaning the back of the hopper 3 as described above, the control device 50 may appropriately change the range of movement of the cleaning unit 10 in the front-to-back direction 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 the process of cleaning the storage space 2A of the waste storage section 2. The control device 50 controls the forward and backward movement drive unit 40 to move the cleaning unit 10 forward to the vicinity of the opening 2B of the waste storage section 2. The control device 50 controls the forward and 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, so that the inside of the storage space 2A can be effectively cleaned. 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 each nozzle 16, 17, 18. At this time, the control device 50 cleans the inside of the storage space 2A while moving the cleaning unit 10 in the positive rotation direction and / or the negative rotation direction. The control device 50 rotates the cleaning unit 10 in a range of, for example, -40° to +55°. In addition, during the process of cleaning the storage space 2A, the control device 50 may appropriately change the rotation range of the cleaning unit 10 according to the degree of inclination of the waste storage section 2.

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

[0043] (Summary of Embodiment 1) The cleaning device 100 according to Embodiment 1 is a cleaning device 100 for cleaning a vehicle, comprising a cleaning unit 10 that extends along the vehicle width direction and has a plurality of nozzles 16, 17, 18 that spray cleaning fluid along the extension direction, and a pair of guide rails 20 that extend along the vehicle length direction and guide the movement of the cleaning unit 10. The pair of guide rails 20 are provided so that a vehicle can enter between the guide rails 20, the cleaning unit 10 is rotatable around a rotation axis A1 that extends along the vehicle width direction, and the nozzles 16, 17, 18 are located away from the rotation axis A1.

[0044] Because the nozzles 16, 17, and 18 are positioned away from the rotation axis A1 (eccentrically), the vertical spray position can be changed as the cleaning unit 10 rotates without moving the cleaning unit 10 itself in the vertical direction. Furthermore, as the cleaning unit 10 moves in the front-rear direction along the guide rail 20 that extends in the vehicle length direction, it can be cleaned at an appropriate distance to match the shape of the vehicle.

[0045] Specifically, if the vehicle is a garbage truck 1, the hopper 3 of the garbage truck 1 can be cleaned at an appropriate distance whether it is open or closed. Therefore, the garbage truck 1 can be cleaned effectively.

[0046] [Embodiment 2] Other embodiments of the present disclosure will be described below with reference to Figure 7. Figure 7 is a side view showing an overview of the cleaning device 100A according to Embodiment 2. For the sake of convenience of explanation, the same reference numerals are used for components having the same function as those described in the above embodiments, and their descriptions will not be repeated. The cleaning device 100A according to Embodiment 2 differs from the cleaning device 100 of Embodiment 1 in that the cleaning unit 10 is supported below the pair of guide rails 20. For the sake of explanation, Figure 7 shows the cleaning unit 10 in both a rear standby position and a position moved below the hopper 3.

[0047] As shown in Figure 7, the cleaning device 100A is equipped with a pair of support members 25. The upper ends of the pair of support members 25 are attached to each of the pair of guide rails 20 and are movable on the guide rails 20. The height of the pair of guide rails 20 should be such that a person walking underneath 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 collection section 2. When the forward / backward 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 forward / backward direction.

[0048] The cleaning unit 10 is attached to the lower end 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 Figure 7, for the sake of clarity, 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 a pair of support members 25. The pair of guide rails 20 are positioned higher than the rotation axis A2 in the vertical direction. The cleaning unit 10 is positioned so that the rotation axis A2 is approximately 150 cm above the installation surface on which the cleaning device 100A is installed, in order to enable cleaning of the inside of the packer truck 1. By positioning the pair of guide rails 20 at a higher position, the possibility of a person colliding with the guide rails 20 when a person passes underneath them can be reduced.
