Description

Technical Field

[0001] The present invention relates to a garbage collection vehicle.

Background Art

[0002] Garbage collection vehicles having a garbage storage box mounted on a vehicle deck have been conventionally known. For example, Patent Document 1 describes a garbage collection vehicle that includes a garbage storage box, a garbage input box into which garbage is input, a loading device that loads the input garbage into the garbage storage box, and a discharge plate disposed inside the garbage storage box so as to be movable in the front-rear direction. The discharge plate partitions the inside of the garbage storage box in the front-rear direction. The discharge plate is gradually moved forward when storing garbage, and is moved rearward by a hydraulic cylinder when discharging garbage. By such rearward movement of the discharge plate, the garbage stored in the garbage storage box can be discharged.

[0003] The garbage collection vehicle described in Patent Document 1 further includes position detection means for detecting the position of the discharge plate in the front-rear direction, and a display unit attached to the garbage input box and configured to display the detected position of the discharge plate facing rearward. An operator can grasp the loaded amount of garbage by checking the display on the display unit.

Summary of Invention

Problems to be Solved by the Invention

[0005] The present invention aims to make it easier to confirm the position of the discharge plate in a garbage collection vehicle.

Means for Solving the Problems

[0006] The refuse collection vehicle of the present invention comprises: a refuse container having an opening that opens toward the rear; a loading device provided behind the refuse container for loading refuse into the refuse container from the opening; a discharge plate provided to partition the inside of the refuse container front to back and moves in the front-rear direction inside the refuse container according to the amount of refuse loaded; a discharge device that moves the discharge plate rearward to discharge the loaded refuse from the refuse container; a position detection device for detecting the front-rear position of the discharge plate; a left-side display device provided on the left side of the refuse container for displaying a gauge indicating the front-rear position of the discharge plate detected by the position detection device; and a right-side display device provided on the right side of the refuse container for displaying a gauge indicating the front-rear position of the discharge plate detected by the position detection device.

[0007] According to the above-mentioned refuse collection vehicle, gauges indicating the front-to-back position of the discharge plate are displayed on a left-side display device located on the left side of the refuse collection box and a right-side display device located on the right side. Therefore, the position of the discharge plate can be intuitively determined by the gauges, regardless of whether the refuse collection vehicle is viewed from the left or the right. This makes it easier to confirm the position of the discharge plate.

[0008] According to a preferred embodiment of the present invention, the left-side display device and the right-side display device are electronic display devices configured to display in characters the status of the refuse collection vehicle, including during loading operations when the loading device is in operation and during discharge operations when the discharge device is in operation, and the gauge is displayed along with the characters only during loading operations.

[0009] In this configuration, the gauge is not displayed when loading operations are not in progress. Therefore, other information can be displayed in the space where the gauge would normally be on the left and right display devices.

[0010] According to a preferred embodiment of the present invention, the left-side display device and the right-side display device are longer in the front-to-back direction than in the vertical direction. The gauge is longer in the front-to-back direction than in the vertical direction and represents the ratio of the space in front of the discharge plate to the space behind the discharge plate within the internal space of the waste collection box by distinguishing between the front and back sides by the color of the light or whether the light is on or off.

[0011] In this embodiment, the gauges of the left and right display devices are configured such that the direction of movement of the discharge plate is in the longitudinal direction, and the display increases or decreases along the direction of movement of the discharge plate. Therefore, visibility is good, and the position of the discharge plate can be intuitively grasped.

[0012] According to a preferred embodiment of the present invention, the left-side display device is configured to show the ratio of the space in front of the discharge plate within the internal space of the waste container using a front-side gauge, and the ratio of the space behind the discharge plate using a rear-side gauge. The right-side display device is configured to display the gauges inverted from those of the left-side display device, showing the ratio of the space in front of the discharge plate within the internal space of the waste container using a front-side gauge, and the ratio of the space behind the discharge plate using a rear-side gauge.

[0013] According to this configuration, instead of simply displaying the same gauge on the left and right display devices, the display is inverted so that the orientation of the display on either gauge aligns with the front-to-back direction of the garbage collection vehicle. This makes the gauge display even easier to understand.

[0014] According to one preferred embodiment of the above, the left-side display device and the right-side display device are electronic display devices configured to display in characters that the loading device is in operation, and display the gauge along with the characters indicating that the loading operation is in progress. According to this embodiment, the left-side display device and the right-side display device display the characters in the same way, but invert the display of the gauge.

[0015] According to a preferred aspect of the present invention, the left-side display device and the right-side display device are configured to be capable of lighting the gauge in a plurality of lighting colors, and light the gauge in a lighting color predetermined corresponding to the position of the discharge plate.

[0016] According to this aspect, an operator can grasp the approximate position of the discharge plate only by confirming the display color of the gauge.

[0017] According to a preferred aspect of the present invention, the garbage truck further includes a garbage input box connected to the garbage storage box from the rear, and a rear display device provided on the rear surface of the garbage input box and configured to display an indication representing the position of the discharge plate in the front-rear direction detected by the position detection device.

[0018] According to this aspect, the position of the discharge plate can be confirmed even from the rear position of the garbage input box where workers are often present during loading work. [Effects of the Invention]

[0019] According to the garbage truck described above, the position of the discharge plate can be confirmed more easily. [Brief Description of the Drawings]

[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 is a left side view of the garbage collection vehicle 10 according to one embodiment. Figure 2 is a right side view of the garbage collection vehicle 10. Figure 3 is a rear view of the garbage collection vehicle 10. Figure 4 is a side view of the loading device 20. As shown in Figure 1 and Figure 2, the garbage collection vehicle 10 according to the present embodiment includes a chassis 11, a garbage storage box 12 mounted on the chassis 11, and a garbage input box 13 connected to the garbage storage box 12 from the rear. A cab 14 is provided in front of the garbage storage box 12. As shown in Figure 4, inside the garbage input box 13, there is provided the loading device 20 that feeds the garbage 5 input into the garbage input box 13 to the garbage storage box 12.

[0022] The garbage storage box 12 is a box that stores the garbage 5. As shown in Figure 4, the garbage storage box 12 is provided with a rear opening 12a that opens toward the rear. The rear surface of the garbage storage box 12 is, here, substantially entirely open. The garbage input box 13 is a box into which the garbage 5 is input. The front surface of the garbage input box 13 is provided with a front opening 13a that opens toward the front. The rear opening 12a of the garbage storage box 12 and the front opening 13a of the garbage input box 13 are connected. The interior of the garbage storage box 12 and the interior of the garbage input box 13 communicate with each other through the rear opening 12a of the garbage storage box 12 and the front opening 13a of the garbage input box 13. An input port 13b is formed at the rear part of the garbage input box 13. The garbage 5 is input into the interior of the garbage input box 13 through the input port 13b.

[0023] The loading device 20 is located behind the refuse container 12 and loads refuse 5 into the refuse container 12 through the rear opening 12a of the refuse container 12. As shown in Figure 4, the loading device 20 includes a sliding plate 21, a sliding cylinder 22, a compression plate 23, and a swinging cylinder 24. The sliding cylinder 22 is connected to the sliding plate 21. The extension and retraction of the sliding cylinder 22 causes the sliding plate 21 to reciprocate up and down. The compression plate 23 is supported at the lower end of the sliding plate 21 so as to be able to swing in the longitudinal direction of the vehicle body. The swinging cylinder 24 is connected to the compression plate 23. The extension and retraction of the swinging cylinder 24 causes the compression plate 23 to swing back and forth.

[0024] Figure 5 is a side view of the loading device 20 while it is compressing the waste 5. As shown in Figure 5, the loading device 20 compresses the waste 5 by swinging the compression plate 23 forward when the sliding plate 21 is in the lowered position. Then, by raising the sliding plate 21, the waste 5 that has been put into the waste input box 13 is loaded into the waste storage box 12. However, the configuration of the loading device 20 is not limited to that described above.

[0025] As shown in Figure 4, a discharge plate 15 is provided inside the refuse container 12. The discharge plate 15 is provided to divide the inside of the refuse container 12 into front and rear sections. The discharge plate 15 has a cross-sectional shape that is approximately the same as the internal space 12I of the refuse container 12. The discharge plate 15 is configured to be movable in the front-to-back direction inside the refuse container 12. The discharge plate 15 moves in the front-to-back direction inside the refuse container 12 according to the amount of refuse 5 that has been loaded.

[0026] As shown in Figure 1, the refuse collection vehicle 10 includes a discharge device 30 for moving the discharge plate 15 and a position detection device 40 for detecting the front-rear position of the discharge plate 15. The discharge device 30 is located in the space 12F in front of the discharge plate 15 within the internal space 12I of the refuse collection box 12. The discharge device 30 includes an extendable discharge cylinder 31. The base end (rear end) of the discharge cylinder 31 is connected to the discharge plate 15. The tip (front end) of the discharge cylinder 31 is connected to the front wall of the refuse collection box 12. However, the configuration of the discharge device 30 is not limited to that described above. The discharge device 30 may, for example, include a link mechanism connecting the discharge cylinder 31 and the discharge plate 15.

[0027] When the pressure of the rubbish 5 pushed into the rubbish container 12 exceeds a predetermined pressure, the discharge cylinder 31 retracts and the discharge plate 15 moves forward. As a result, the discharge plate 15 moves back and forth inside the rubbish container 12 according to the amount of rubbish 5 loaded. When the rubbish 5 is to be discharged, the discharge device 30 moves the discharge plate 15 backward by extending the discharge cylinder 31, and discharges the loaded rubbish 5 from the rubbish container 12.

[0028] The position detection device 40 here includes an optical distance sensor 41 that measures the distance to the discharge plate 15. The distance sensor 41 is mounted on the front wall of the waste collection box 12. However, the method by which the position detection device 40 detects the position of the discharge plate 15 is not limited to the above. The position detection device 40 may be configured, for example, to detect the position of the rod of the discharge cylinder 31.

[0029] As shown in Figures 1 and 2, the refuse collection vehicle 10 according to this embodiment includes a left message board 50 provided on the left side of the refuse container 12 and a right message board 60 provided on the right side of the refuse container 12. The left message board 50 and the right message board 60 are positioned on the upper left and upper right sides of the refuse container 12, respectively. Here, the left message board 50 and the right message board 60 are positioned above the left half and right half of the refuse container 12, respectively, for better visibility. As shown in Figure 3, the left message board 50 is provided in a recess on the left side of the refuse container 12 and is positioned so as not to protrude beyond the leftmost part of the refuse input box 13 (and the leftmost part of the refuse container 12, not shown). The right message board 60 is positioned similarly.

[0030] The left message board 50 and the right message board 60 are electronic display devices configured to display text indicating the status of the refuse collection vehicle 10, including during loading operations when the loading device 20 is in operation and during discharge operations when the discharge device 30 is in operation. Figure 6 is a left side view of the left message board 50. Figure 7 is a right side view of the right message board 60. As shown in Figures 6 and 7, the left message board 50 and the right message board 60 display the text "Loading in Progress" 51 and 61 respectively when loading operations are in operation when the loading device 20 is in operation. Figure 8 is a left side view of the left message board 50 during discharge operations. As shown in Figure 8, during discharge operations when the discharge device 30 is in operation, the left message board 50 displays the text "Discharge in Progress" 51. Although not shown in the illustration, the right message board 60 also displays the text "Discharge in Progress" 61 at this time.

[0031] The left message board 50 and the right message board 60 may scroll the characters 51 and 61 in the front-to-back direction of the garbage collection vehicle 10, or they may flash. Alternatively, the left message board 50 and the right message board 60 may display the characters 51 and 61 in a fixed position. The left message board 50 and the right message board 60 may also display the characters 51 and 61 in predetermined colors depending on the content, for example, displaying the characters "Loading in Progress" in a first color and the characters "Discharging in Progress" in a second color.

[0032] During loading, the left message board 50 and the right message board 60 display characters 51 and 61 indicating that loading is in progress, along with gauges 52 and 62 indicating the front-to-back position of the discharge plate 15 detected by the position detection device 40. Hereinafter, when necessary, the gauge displayed on the left message board 50 will also be called the left gauge 52, and the gauge displayed on the right message board 60 will also be called the right gauge 62. The left message board 50 and the right message board 60 display gauges 52 and 62 along with characters 51 and 61 only during loading. When not loading, the left message board 50 and the right message board 60 display other information, such as the characters "Interlocking," as shown in Figure 8, and do not display gauges 52 and 62. The left message board 50 and the right message board 60 are not dedicated display devices for indicating the amount of rubble 5 loaded, but rather general-purpose display devices that display various information.

[0033] As shown in Figures 6 and 7, the left message board 50 and the right message board 60 are configured in a flat rectangular shape, longer in the front-to-back direction than in the up-to-down direction. The left gauge 52 and the right gauge 62 are also configured to be longer in the front-to-back direction than in the up-to-down direction. As shown in Figure 6, the left gauge 52 has a plurality of illuminated areas 53 arranged in the front-to-back direction. Each illuminated area 53 is configured in a roughly rectangular shape. Preferably, the number of illuminated areas 53 is 10 or more. More preferably, the number of illuminated areas 53 is 20 or more. The more illuminated areas 53 there are, the finer the display resolution of the left gauge 52. Each illuminated area 53 can be illuminated in multiple colors and can be turned off (here, this means displaying only the outer frame, however, it is not necessary to display even the outer frame). The left message board 50 and the right message board 60 are configured to illuminate the gauges 52 and 62 in multiple colors. The right message board 60 also has a plurality of illuminated areas 63 similar to the illuminated areas 53 of the left message board 50.

[0034] The left gauge 52 and the right gauge 62 are configured to represent the ratio of the space 12F in front of the discharge plate 15 and the space 12R behind the discharge plate 15 within the internal space 12I of the refuse container 12, respectively, by distinguishing between the front and rear by the illuminated color or illumination / non-illumination of the illuminated areas 53 and 63. Here, the left gauge 52 and the right gauge 62 represent the space 12R (the space where refuse 5 is already loaded) in the internal space 12I of the refuse container 12 (the space where refuse 5 can still be loaded) by the illumination of the illuminated areas 53 and 63, respectively. The left gauge 52 and the right gauge 62 represent the space 12F (the space where refuse 5 can still be loaded) in the internal space 12I of the refuse container 12 (the space where refuse 5 can still be loaded) by the non-illumination of the illuminated areas 53 and 63, respectively. However, the states represented by illumination / non-illumination may be reversed. Furthermore, the left gauge 52 and the right gauge 62 may each represent, with a first lighting color, the space 12R (the space where the waste 5 is already loaded) behind the discharge plate 15 within the internal space 12I of the waste collection box 12 (the space in front of which more waste 5 can still be loaded) and a second lighting color different from the first color.

[0035] As shown in Figure 6, the left message board 50 is configured to represent the ratio of the space 12F in front of the discharge plate 15 within the internal space 12I of the refuse collection box 12 using the front gauge 52F (group of unlit illuminated areas 53), and the ratio of the space 12R behind the discharge plate 15 using the rear gauge 52R (group of illuminated areas 53). The right message board 60 is configured to display the gauges in reverse from the left message board 50. As shown in Figure 7, this inversion causes the right message board 60 to also represent the ratio of the space 12F in front of the discharge plate 15 within the internal space 12I of the refuse collection box 12 using the front gauge 62F (group of unlit illuminated areas 63), and the ratio of the space 12R behind the discharge plate 15 using the rear gauge 62R (group of illuminated areas 63).

[0036] The left message board 50 and the right message board 60 are configured to illuminate gauges 52 and 62 with predetermined colors corresponding to the position of the discharge plate 15. Here, the left message board 50 and the right message board 60 illuminate the rear gauges 52R and 62R, respectively, with predetermined colors corresponding to the position of the discharge plate 15. For example, when the discharge plate 15 is moved forward beyond a predetermined position close to the very front, the left message board 50 and the right message board 60 illuminate the rear gauges 52R and 62R with different colors than before.

[0037] Figure 9 is a left side view of the refuse collection truck 10 when the amount of refuse 5 loaded is just before full capacity. Figure 10 is a left side view of the left message board 50 when the amount of refuse 5 loaded is just before full capacity. Figure 11 is a right side view of the right message board 60 when the amount of refuse 5 loaded is just before full capacity. In the state shown in Figure 9, the discharge plate 15 is located in front of a predetermined position P1, which is the boundary for changing the illumination color. As shown in Figure 10, when the discharge plate 15 is moved in front of the predetermined position P1, the left message board 50 illuminates the rear gauge 52R with a different illumination color (represented by different hatching) than in Figure 6. The same applies to the right message board 60; when the discharge plate 15 is moved in front of the predetermined position P1, as shown in Figure 11, it illuminates the rear gauge 62R with a different illumination color than in Figure 7, but the same illumination color as the left message board 50. The right message board 60 displays the gauge display inverted compared to the left message board 50.

[0038] As shown in Figure 3, the refuse collection vehicle 10 is further equipped with a rear message board 70 located on the rear surface of the refuse input box 13. The rear message board 70 is also an electronic display device capable of displaying various information. The rear message board 70 also displays the front-rear position of the discharge plate 15 detected by the position detection device 40, specifically the left and right gauges 71L and 71R. The rear message board 70 also displays the status of the refuse collection vehicle 10, including during loading and unloading operations, in text. As shown in Figure 3, a text display area 72 is provided in the center of the rear message board 70 in the left-right direction. The left and right gauges 71L and 71R are located to the left and right of the text display area 72, respectively.

[0039] The gauge 71L on the left side here has four illuminated areas 73L arranged in the left-right direction. Each illuminated area 73L is roughly rectangular in shape. It is preferable that the number of illuminated areas 73L be four or more. This is because, as will be described later, the text display area 72 displays that the amount of rubbish 5 loaded has exceeded half the capacity of the rubbish container 12 and that it is almost full. If the number of illuminated areas 73L is three or less, it is difficult to distinguish between the amount of rubbish 5 loaded exceeding half and being almost full. In the gauge 71L on the left side, the right side (towards the center of the vehicle width) corresponds to the front of the rubbish collection vehicle 10. In the gauge 71L on the left side, the ratio of the space 12R behind the discharge plate 15 is represented by the same illuminated color as the left message board 50 and the right message board 60.

[0040] The gauge 71R on the right is configured similarly to the gauge 71L on the left. However, the gauge 71R on the right is configured in a left-right inversion compared to the gauge 71L on the left, with the left side (towards the center of the vehicle width) corresponding to the front of the garbage collection vehicle 10.

[0041] As shown in Figure 3, when the position of the discharge plate 15 exceeds the position corresponding to half of the waste collection box 12, the text display area 72 of the rear message board 70 displays text indicating that the load has exceeded half, in this case the text "Half full." Although not shown in the illustration, when the position of the discharge plate 15 exceeds a predetermined position P1, the text display area 72 of the rear message board 70 displays text indicating that the load is close to full, for example, the text "Almost full."

[0042] [Effects of the Embodiment] As described above, the refuse collection vehicle 10 according to this embodiment includes a position detection device 40 for detecting the front-rear position of the discharge plate 15, a left message board 50 provided on the left side of the refuse collection box 12 and displaying a left gauge 52 indicating the front-rear position of the discharge plate 15 detected by the position detection device 40, and a right message board 60 provided on the right side of the refuse collection box 12 and displaying a right gauge 62 indicating the front-rear position of the discharge plate 15 detected by the position detection device 40. With such a refuse collection vehicle 10, the position of the discharge plate 15 can be intuitively grasped by the gauge 52 or 62, regardless of whether the refuse collection vehicle 10 is viewed from the left or right side. This makes it easier to confirm the position of the discharge plate 15.

[0043] In this embodiment, the left message board 50 and the right message board 60 are electronic display devices configured to display the status of the refuse collection vehicle 10 in text, including during loading operations when the loading device 20 is in operation and during discharge operations when the discharge device 30 is in operation. The left message board 50 and the right message board 60 display gauges 52 and 62 along with text only during loading operations. With this configuration, gauges 52 and 62 are not displayed when loading operations are not in operation. Therefore, other information (for example, the text information in Figure 8) can be displayed in the place of gauges 52 and 62. There is not much need to display gauges 52 and 62 when loading operations are not in operation.

[0044] In this embodiment, the left message board 50 and the right message board 60 are configured to be longer in the front-to-back direction than in the up-to-down direction. The gauges 52 and 62 are also longer in the front-to-back direction than in the up-to-down direction, and represent the ratio of the space 12F in front of the discharge plate 15 and the space 12R behind it within the internal space 12I of the waste collection box 12, distinguishing between the front and back by the color of the lights or whether they are lit or not. With this configuration, the left gauge 52 and the right gauge 62 are configured so that the direction of movement of the discharge plate 15 is in the longitudinal direction, and the display increases or decreases along the direction of movement of the discharge plate 15. As a result, visibility is very good, and the position of the discharge plate 15 can be intuitively grasped.

[0045] In this embodiment, the left message board 50 is configured to show the ratio of the space 12F in front of the discharge plate 15 within the internal space 12I of the refuse collection box 12 using the front gauge 52F, and the ratio of the space 12R behind the discharge plate 15 using the rear gauge 52R. The right message board 60 is configured to display the gauges inverted from the left message board 50, showing the ratio of the space 12F in front of the discharge plate 15 within the internal space 12I of the refuse collection box 12 using the front gauge 62F, and the ratio of the space 12R behind the discharge plate 15 using the rear gauge 62R. With this configuration, instead of simply displaying the same image on the left and right gauges 52 and 62, the display is inverted, so that the orientation of the display on either gauge 52 or 62 matches the front-to-back direction of the refuse collection vehicle 10. This makes the displays on the gauges 52 and 62 even easier to understand. Furthermore, as shown in Figures 6 and 7, the words "Loading in Progress" 51 and 61 on the left message board 50 and the right message board 60 are not reversed or rearranged to be inverted. Therefore, the display on the left message board 50 and the display on the right message board 60 are not simply alternating front to back.

[0046] In this embodiment, the left message board 50 and the right message board 60 are configured to illuminate gauges 52 and 62 in multiple colors, and the gauges 52 and 62 are illuminated in predetermined colors corresponding to the position of the discharge plate 15. With this configuration, the worker can grasp the approximate position of the discharge plate 15 simply by checking the display color of gauge 52 or 62.

[0047] The refuse collection vehicle 10 according to this embodiment is further equipped with a rear message board 70 provided on the rear surface of the refuse input box 13, which displays an indication of the front-rear position of the discharge plate 15 detected by the position detection device 40. With this configuration, the position of the discharge plate 15, that is, the current load amount of refuse 5 and the remaining possible load amount, can be checked from the rear position of the refuse input box 13, where workers are often located during loading operations.

[0048] [Other embodiments] A preferred embodiment of the present invention has been described above. However, the above embodiment is merely one example of an embodiment of the present invention. The present invention can be implemented in various other forms.

[0049] For example, in the above embodiment, the refuse collection vehicle 10 was equipped with a rear message board 70. However, the refuse collection vehicle 10 does not need to be equipped with a rear message board 70. In the above embodiment, the left message board 50 and the right message board 60 were configured to also display text information. However, the left message board 50 and the right message board 60 may each only display gauges 52 and 62 indicating the position of the discharge plate 15.

[0050] Gauges 52 and 62 do not necessarily have to be divided into multiple illuminated areas 53 and 63 arranged in the front-to-back direction. Gauges 52 and 62 may, for example, represent the position of the discharge plate 15 as bar-shaped gauges without any particular divisions. The display configuration of gauges 52 and 62 is not particularly limited.

[0051] In the above embodiment, the left message board 50 and the right message board 60 were located on the upper left and right sides of the waste container 12, respectively.
