Description

[Technical Field]

[0001] The present invention relates to a refuse collection vehicle having a safety confirmation member that enables safety confirmation behind the vehicle body. [Background technology]

[0002] A refuse collection truck has a loading box for storing refuse in the loading platform, and the loading port for loading the refuse into the loading box is provided on the rear side of the vehicle body. There are many blind spots behind such refuse collection trucks from the driver's seat. Therefore, refuse collection trucks have been devised that are equipped with a surveillance camera that shows the rear of the vehicle body to eliminate blind spots, and such refuse collection trucks are disclosed, for example, in Patent Documents 1 and 2. The refuse collection trucks disclosed in Patent Documents 1 and 2 are configured so that safety behind the vehicle body can be confirmed regardless of whether the loading port door is open or closed by installing a surveillance camera outside the loading port door. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-314061 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-105168 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional garbage collection vehicles such as those disclosed in Patent Documents 1 and 2, the surveillance camera is positioned behind (outside) the drop-in door, so when the drop-in door is opened, even if an attempt is made to photograph the drop-in door, the drop-in door enters the surveillance camera's field of view, obstructing the photograph.

[0005] Therefore, an object of the present invention is to provide a garbage collection vehicle in which the drop-in door does not interfere with the safety confirmation function of the safety confirmation member. [Means for solving the problem]

[0006] A first aspect of the present invention for solving the above problem is a garbage collection vehicle having a cargo box mounted on a vehicle body, the cargo box having a storage section for storing garbage, an inlet for putting garbage into the storage section, and a door for opening and closing the inlet, the inlet being provided on the rear side of the vehicle body in the cargo box, a fixed wall facing the rear of the vehicle body being provided above the inlet in the cargo box, the fixed wall being provided with a safety confirmation member visible from the rear of the vehicle body, and the door being movable behind the safety confirmation member and above the safety confirmation member.

[0007] In this aspect, the packing box has a storage section for storing garbage, an inlet for putting garbage into the storage section, and a door for opening and closing the inlet, the inlet is provided on the rear side of the car body of the packing box, a fixed wall facing the rear of the car body is provided above the inlet of the packing box, and a safety confirmation member visible from the rear of the car body is provided on the fixed wall, and the door is movable behind the safety confirmation member and above the safety confirmation member. Therefore, when the door closes the opening, the door is located below the safety confirmation member, and when the door opens the opening to allow garbage to be dropped in, the door is located above the safety confirmation member. In other words, when the door closes the opening and when the door opens the opening to allow garbage to be dropped in, the door is not located behind the safety confirmation member. In other words, there is no obstacle that would impair the safety confirmation function of the safety confirmation member. Therefore, the safety confirmation member can perform its safety confirmation function not only when the door closes the opening, but also when garbage is being dropped into the storage section of the shipping box. Specifically, if the safety confirmation member is a surveillance camera, the door does not obstruct the surveillance camera's filming, allowing it to clearly capture the situation at the drop-off port and behind the vehicle. Also, if the safety confirmation member is an indicator light, nearby people behind the refuse collection truck can see the safety confirmation member. This allows them to know that the refuse collection truck is in operation, draws their attention, and helps them avoid dangerous behavior, such as carelessly approaching the refuse collection truck.

[0008] A second aspect of the present invention is a garbage collection vehicle having a loading box mounted on a vehicle body, the loading box having a storage section for storing garbage, an inlet for dumping garbage into the storage section, and a door for opening and closing the inlet, the inlet being provided on the rear side of the vehicle body in the loading box, a fixed wall facing the rear of the vehicle body is provided above the inlet in the loading box, and a safety confirmation member visible from the rear of the vehicle body is provided on the fixed wall, guide rails are provided on both sides of the inlet, the guide rails extend from at least the height of the lower end of the inlet and at least higher than the safety confirmation member, the guide rails are constantly engaged with the lower part of the door, and the door is movable behind the safety confirmation member.

[0009] In a second aspect, the packing box has a storage section for storing garbage, an inlet for putting garbage into the storage section, and a door for opening and closing the inlet, the inlet is provided on the rear side of the car body of the packing box, a fixed wall facing the rear of the car body is provided above the inlet of the packing box, and a safety confirmation member visible from the rear of the car body is provided on the fixed wall, and the door is movable behind the safety confirmation member. Therefore, when the door closes the opening, the door is located below the safety confirmation member, and when the door opens the opening to allow garbage to be dropped in, the door is located above the safety confirmation member. In other words, when the door closes the opening and when the door opens the opening to allow garbage to be dropped in, the door is not located behind the safety confirmation member. In other words, there is no obstacle that would impair the safety confirmation function of the safety confirmation member. Therefore, the safety confirmation member can perform its safety confirmation function not only when the door closes the opening, but also when garbage is being dropped into the storage section of the shipping box. Specifically, if the safety confirmation member is a surveillance camera, the door does not obstruct the surveillance camera's filming, allowing it to clearly capture the situation at the drop-off port and behind the vehicle. Also, if the safety confirmation member is an indicator light, nearby people behind the refuse collection truck can see the safety confirmation member. This allows them to know that the refuse collection truck is in operation, draws their attention, and helps them avoid dangerous behavior, such as carelessly approaching the refuse collection truck. In this aspect, guide rails are provided on both sides of the insertion port, and the guide rails extend from at least the height position of the lower end of the insertion port at least above the safety confirmation member.The guide rails are constantly engaged with the lower part of the door, so that the lower part of the door moves along the guide rails, and the door can move above the safety confirmation member or below the safety confirmation member. Here, the "lower part" of the door refers to the underside, lower edge, and near the bottom end of the side of the door. In addition, because only the lower part of the door engages with the guide rail, the door can swing around the engaged part of the lower part as a base point. Therefore, when the door moves upward, it can swing around the lower part as a base point to change its position so that it does not collide with the safety confirmation member. Therefore, even if a safety confirmation member is placed directly above the door when the insertion port is closed, the top of the door can be swung backward when the door rises, preventing the door from coming into contact with the safety confirmation member. This allows the door to move behind the safety confirmation member without coming into contact with or colliding with the safety confirmation member when the door opens the slot. Furthermore, because the door can move higher than the safety confirmation member, the door is not located behind the safety confirmation member. Therefore, there are no obstacles behind the safety confirmation member, allowing the safety confirmation member to perform its safety confirmation function.

[0010] A third aspect of the present invention is a garbage collection vehicle having a loading box mounted on a vehicle body, the loading box comprising a storage section for storing garbage, an inlet through which garbage is dumped into the storage section, and a door for opening and closing the inlet, the inlet being provided on the rear side of the vehicle body of the loading box, a fixed wall facing the rear of the vehicle body is provided above the inlet of the loading box, the fixed wall is provided with a safety confirmation member that is visible from the rear of the vehicle body, the door is provided with a protruding engagement section that protrudes downward, and guide rails are provided on both sides of the inlet, the guide rails extend from a height position that is lower than the height position of the bottom end of the inlet by at least the protruding length of the protruding engagement section from the door, to at least the height position of the bottom end of the fixed wall, the protruding engagement section is constantly engaged with the guide rails, and the door is movable behind the safety confirmation member.

[0011] According to a third aspect, the packing box has a storage section for storing garbage, an inlet for putting garbage into the storage section, and a door for opening and closing the inlet, the inlet is provided on the rear side of the car body of the packing box, a fixed wall facing the rear of the car body is provided above the inlet of the packing box, and a safety confirmation member visible from the rear of the car body is provided on the fixed wall, and the door is movable behind the safety confirmation member. Therefore, when the door closes the opening, the door is located below the safety confirmation member, and when the door opens the opening to allow garbage to be dropped in, the door is located above the safety confirmation member. In other words, when the door closes the opening and when the door opens the opening to allow garbage to be dropped in, the door is not located behind the safety confirmation member. In other words, there is no obstacle that would impair the safety confirmation function of the safety confirmation member. Therefore, the safety confirmation member can perform its safety confirmation function not only when the door closes the opening, but also when garbage is being dropped into the storage section of the shipping box. Specifically, if the safety confirmation member is a surveillance camera, the door does not obstruct the surveillance camera's filming, allowing it to clearly capture the situation at the drop-off port and behind the vehicle. Also, if the safety confirmation member is an indicator light, nearby people behind the refuse collection truck can see the safety confirmation member. This allows them to know that the refuse collection truck is in operation, draws their attention, and helps them avoid dangerous behavior, such as carelessly approaching the refuse collection truck. In this aspect, the door is provided with a protruding engagement portion that protrudes downward, and guide rails are provided on both sides of the insertion port. The guide rails extend from a height position that is lower than the height position of the lower end of the insertion port by at least the protruding length of the protruding engagement portion from the door, to at least the height position of the lower end of the fixed wall, and the protruding engagement portion is constantly engaged with the guide rails. Therefore, the protruding engagement portion moves along the guide rail, and the door can move above the safety confirmation member or below the safety confirmation member. Furthermore, because only the protruding engagement portion that protrudes downward of the door engages with the guide rail, the door can swing around the point where the protruding engagement portion engages with the guide rail. Therefore, when the door moves upward, it can swing around the point where the protruding engagement portion engages with the guide rail to change its position so that it does not collide with the safety confirmation member.

[0012] A fourth aspect of the present invention is a garbage collection vehicle having a loading box mounted on a vehicle body, the loading box having a storage section for storing garbage, an inlet for dumping garbage into the storage section, and a door for opening and closing the inlet, the inlet being provided on the rear side of the vehicle body in the loading box, a fixed wall facing the rear of the vehicle body being provided above the inlet in the loading box, and a safety confirmation member visible from the rear of the vehicle body being provided on the fixed wall, the lower part of the door having a recessed portion or through-hole that is recessed in the height direction, the door being able to open and close the inlet by raising and lowering behind the safety confirmation member, and the garbage collection vehicle characterized in that when the door opens the inlet, the recessed portion or through-hole in the door is at the height position of the safety confirmation member.

[0013] In a fourth aspect of the present invention, a shipping box includes a storage section for storing garbage, an inlet for inserting garbage into the storage section, and a door for opening and closing the inlet, the inlet is provided on the rear side of the shipping box, a fixed wall facing the rear of the shipping box is provided above the inlet in the shipping box, and a safety confirmation member visible from the rear of the shipping box is provided on the fixed wall, and a recessed section or through-hole recessed in the height direction is provided at the bottom of the door, and the door can be raised and lowered behind the safety confirmation member to open and close the inlet, and when the door opens the inlet, the recessed section or through-hole of the door is at the height position of the safety confirmation member. Therefore, when the door closes the opening, the door is located below the safety confirmation member, and when the door opens the opening to allow garbage to be dropped in, the door is located above the safety confirmation member. In other words, when the door closes the opening and when the door opens the opening to allow garbage to be dropped in, the door is not located behind the safety confirmation member. In other words, there is no obstacle that would impair the safety confirmation function of the safety confirmation member. Therefore, the safety confirmation member can perform its safety confirmation function not only when the door closes the opening, but also when garbage is being dropped into the storage section of the shipping box. Specifically, if the safety confirmation member is a surveillance camera, the door does not obstruct the surveillance camera's filming, allowing it to clearly capture the situation at the drop-off port and behind the vehicle. Also, if the safety confirmation member is an indicator light, nearby people behind the refuse collection truck can see the safety confirmation member. This allows them to know that the refuse collection truck is in operation, draws their attention, and helps them avoid dangerous behavior, such as carelessly approaching the refuse collection truck.

[0014] It is preferable that a shielding member for shielding the recessed portion of the door or the through hole is provided at the lower end of the insertion opening.

[0015] According to this configuration, when the door closes the insertion opening, the recess or through-hole of the door can be shielded by the shielding member. [Effects of the Invention]

[0016] According to the present invention, the safety confirmation member can effectively perform the safety confirmation function when the door closes the insertion opening and when the door opens the insertion opening to insert garbage. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following description will be given with reference to the drawings. As shown in Figure 1(a), the refuse collection vehicle 1 according to this embodiment has a driver's seat 12 at the front of the vehicle body 1a and a cargo box 2 at the rear. The cargo box 2 has a storage section 2a inside for storing refuse. The periphery of the cargo box 2 is closed, but an opening, an inlet 3 (Figure 2(c)), is provided at the rear. In other words, the inlet 3 is provided at the rear of the refuse collection vehicle 1. The inlet 3 functions as an entrance and exit for refuse. As shown in Figure 2(b), a fixed wall 5 is provided above the inlet 3. In other words, the fixed wall 5 is a wall that separates the upper part of the inlet 3 facing the rear of the refuse collection vehicle 1.

[0019] A safety confirmation member 6 is attached to the fixed wall 5. In this embodiment, the safety confirmation member 6 is a monitoring camera. The safety confirmation member 6 (monitoring camera) can capture an image of the drop inlet 3 or the area behind the garbage collection vehicle 1.

[0020] As shown in FIG. 2(b), an auxiliary door 13 is provided below the insertion slot 3. The auxiliary door 13 rotates around a horizontal axis to open the insertion slot 3. The auxiliary door 13 is provided when the opening area of ​​the insertion slot 3 is larger than that of the door 4. The opening and closing operation of the auxiliary door 13 is the same as that of a known method, and therefore a description thereof will be omitted.

[0021] A receiver (monitor) not shown is provided in the driver's seat 12. The video signal captured by the safety confirmation member 6 is transmitted to the receiver via a signal line not shown or wirelessly, and the worker in the driver's seat 12 can view images of the drop inlet 3 and the area behind the garbage collection vehicle 1 on the receiver.

[0022] As shown in FIGS. 2(a) to 2(c), a door 4 is provided at the drop slot 3. As shown in FIG. 3(b), the door 4 is a substantially rectangular member having an upper edge 4a, a lower edge 4b, and side edges 4c and 4d. Arms 11a and 11b are connected to the upper edge 4a of the door 4. The door 4 is connected to a drive mechanism (not shown) via the arms 11a and 11b. In other words, the arms 11a and 11b are attached to the upper edge 4a of the door 4 so as to be rotatable relative to the door 4. The door 4 and the arms 11a and 11b are connected via pins (not shown).

[0023] 3(b), engagement protrusions 10a, 10b (engagement portions) are provided on the lower portions of both left and right side portions 4c, 4d of the door 4. The engagement protrusions 10a, 10b are cylindrical and protrude toward both the left and right sides of the door 4.

[0024] Meanwhile, guide rails 7a, 7b are provided on both the left and right sides of the insertion slot 3. The guide rails 7a, 7b have a generally U-shaped cross section, have engagement grooves 17a, 17b, and extend in the vertical direction. Lower ends 8a, 8b of the guide rails 7a, 7b are located at a height lower than the lower end 3a of the insertion slot 3. Upper ends 9a, 9b of the guide rails 7a, 7b are located at a height higher than the safety confirmation member 6.

[0025] The distance between the guide rails 7a, 7b is greater than the width of the door 4. Furthermore, the engaging protrusions 10a, 10b of the door 4 engage with the opposing engaging grooves 17a, 17b of the guide rails 7a, 7b. In other words, the lower part of the door 4 is restrained by the guide rails 7a, 7b (engagement grooves 17a, 17b). The engaging protrusions 10a, 10b are movable along the guide rails 7a, 7b and are also rotatable within the guide rails 7a, 7b. The engaging protrusions 10a, 10b are cylindrical in shape and can rotate smoothly within the guide rails 7a, 7b.

[0026] That is, the width of the door 4 is narrower than the distance between the guide rails 7a and 7b, and the door 4 can rotate (swing) around the engaging protrusions 10a and 10b relative to the guide rails 7a and 7b.

[0027] The door 4 is suspended by arms 11a and 11b. As shown in FIG. 2(a), when the door 4 reaches the lowered position, the lower edge 4b ​​of the door 4 abuts or engages with the raised auxiliary door 13, closing the drop opening 3. In other words, the inside and outside of the storage section 2a of the packing box 2 are isolated from each other. When the door 4 reaches the raised position, the drop opening 3 opens.

[0028] When the door 4 rises, the lower part of the door 4 (engagement protrusions 10a, 10b) rises along the guide rails 7a, 7b, and the upper side 4a of the door 4 is pulled by the arms 11a, 11b and moves backward, as shown in FIG. 2(b). In other words, only the engagement protrusions 10a, 10b (FIG. 3(b)) provided on the lower part of the door 4 are constantly engaged with the guide rails 7a, 7b, and the upper side 4a of the door 4 moves (swings) backward. As a result, the door 4 swings around the engagement protrusions 10a, 10b while rising along the guide rails 7a, 7b, and the upper side 4a of the door 4 moves backward.

[0029] A safety confirmation member 6 is attached to the fixed wall 5 that separates the upper part of the insertion slot 3, but as the door 4 rises, the upper edge 4a of the door 4 moves backward, so the door 4 can rise without coming into contact with or colliding with the safety confirmation member 6. In other words, the lower part of the door 4 is engaged with and restrained by the guide rails 7a, 7b, and the upper part of the door 4 is suspended by the arms 11a, 11b, which pull the door 4 upward and backward so that the door 4 passes behind the safety confirmation member 6, thereby changing the position of the door 4.

[0030] Furthermore, both the upper and lower parts of the side edges 4c, 4d of the door 4 may be engaged with the guide rails 7a, 7b (engagement grooves 17a, 17b) so that the upper edge 4a of the door 4 does not swing backward, and furthermore, the part of the fixed wall 5 where the safety confirmation member 6 is attached may be recessed (retracted) forward, so that the safety confirmation member 6 is positioned forward of the movement trajectory of the door 4 that moves along the guide rails 7a, 7b. Even with this configuration, the safety confirmation member 6 can perform its safety confirmation function without being obstructed by the door 24 when the door 24 is fully closed or fully open.

[0031] In the refuse collection vehicle 1 according to this embodiment, the door 4 that opens and closes the inlet 3 through which refuse is put into the storage section 2a moves up and down while passing behind the safety confirmation member 6, so the inlet 3 of the storage section 2a can be located at the rearmost position of the vehicle body 1a. Therefore, the inlet 3 is located at the rearmost position of the vehicle body 1a, making it easy for workers to put refuse into the inlet 3.

[0032] Furthermore, because the dimension that the safety confirmation member 6 protrudes rearward can be reduced, the safety confirmation member 6 does not occupy the surrounding space. Therefore, it is less likely that the safety confirmation member 6 will come into contact with equipment or objects behind the garbage collection vehicle 1. Furthermore, because the door can move behind the safety confirmation member, there is no need to provide a location for attaching the safety confirmation member to the rear of the refuse collection vehicle, nor is there a need for the safety confirmation member to protrude further rearward than the door, which simplifies the structure of the rear of the refuse collection vehicle. Furthermore, since the safety confirmation member can be installed directly above the door when it is in the lowered position with the loading opening closed, the fixed wall on which the safety confirmation member is attached can be positioned close to the position of the door in the lowered position in the longitudinal direction of the vehicle body, thereby ensuring a large capacity for the storage area of ​​the cargo box.

[0033] A surveillance camera, for example, can be used as the safety confirmation member 6. If the images captured by the surveillance camera can be viewed on a monitor (not shown) installed in the driver's seat 12, the worker in the driver's seat 12 can monitor the situation behind the refuse collection vehicle 1 and the situation near the drop-in opening 3. Because there are no obstacles to filming behind the surveillance camera, the surveillance camera can clearly capture images of the rear of the refuse collection vehicle 1 and the drop-in opening 3. In other words, the surveillance camera, which is a safety confirmation member, can fulfill its safety confirmation function.

[0034] Furthermore, an indicator light can also be used as the safety confirmation member 6. When the door 4 is in the lowered position that closes the drop opening 3, and when the door 4 is in the raised position that opens the drop opening 3, people around behind the refuse collection vehicle 1 can see the indicator light. Therefore, the indicator light lets people know that the refuse collection vehicle 1 is in operation, ensuring safety.

[0035] Next, a garbage collection vehicle 21 according to another embodiment will be described with reference to Figures 4 and 5. The garbage collection vehicle 21 shown in Figures 4(a) to 4(c) has a structure that is generally similar to that of the garbage collection vehicle 1 shown in Figure 1, but the structure of the door 24 differs from the structure of the door 4 of the garbage collection vehicle 1. In the following, the same components of the garbage collection vehicle 21 as those of the garbage collection vehicle 1 will be assigned the same reference numerals, and duplicate explanations will be omitted.

[0036] As shown in Figures 5(a) to 5(c), door 24 has an upper edge portion 24a, a lower edge portion 24b, and side edge portions 24c and 24d, and opens and closes drop slot 3 (Figure 4(b)) by moving up and down. Side edge portions 24c and 24d of door 24 do not have engagement protrusions 10a and 10b like those of door 4, but instead have protruding engagement portions 15a and 15b on bottom edge portion 24b. Protruding engagement portions 15a and 15b are bent into a substantially L-shape, and one end thereof is fixed to bottom edge portion 24b of door 24. The other ends of protruding engagement portions 15a and 15b form free ends 16a and 16b, which extend toward the side of door 24.

[0037] As shown in Fig. 5(b), free ends 16a and 16b of protruding engagement portions 15a and 15b protrude outward (toward the side) from side edges 24c and 24d of door 24. As shown in Fig. 5(a) and Fig. 5(c), free ends 16a and 16b engage with engagement grooves 17a and 17b of guide rails 7a and 7b.

[0038] Door 24, like door 4, is suspended from arms 11a, 11b and moves up and down, and when slot 3 is open, protruding engagement portions 15a, 15b are at a height position near upper ends 9a, 9b of guide rails 7a, 7b, and lower edge portion 24b of door 24 is positioned above safety confirmation member 6. In other words, lower edge portion 24b is positioned above upper ends 9a, 9b of guide rails 7a, 7b, but door 24 engages with guide rails 7a, 7b at protruding engagement portions 15a, 15b (free ends 16a, 16b) fixed to lower edge portion 24b.

[0039] That is, the protruding engagement portions 15a, 15b protrude downward from the bottom edge 24b of the door 24, and the length of their downward protrusion is longer than the distance from the height position of the upper ends 9a, 9b of the guide rails 7a, 7b to the height position of the safety confirmation member 6. Therefore, when the free ends 16a, 16b of the protruding engagement portions 15a, 15b come close to the top ends 9a, 9b of the guide rails 7a, 7b, the bottom edge 24b of the door 24 moves higher than the safety confirmation member 6. The safety confirmation member 6 can perform its safety confirmation function without being obstructed by the door 24 when the door 24 is fully closed or fully open.

[0040] Here, the safety confirmation function means that if the safety confirmation member 6 is a surveillance camera, it will take pictures of the drop-in slot 3 and the rear of the vehicle body 1a, and if the safety confirmation member 6 is an indicator light, the indicator light can be seen by people around the garbage collection vehicle 1 and can alert them.

[0041] Figure 6 shows the rear of a refuse collection vehicle 31 according to another embodiment different from those of Figures 2 and 4. In the refuse collection vehicle 31, the structure of the door 34 and auxiliary door 33 differs from the structure of the door 4 and auxiliary door 13 of the refuse collection vehicle 1 of Figure 2.

[0042] The door 34 has an upper edge portion 34a, a lower edge portion 34b, and side edge portions 34c and 34d, and engaging protrusions (not shown) similar to the engaging protrusions 10a and 10b of the door 4 shown in FIG. 3(b) are provided at the bottom of the side edge portions 34c and 34d. The engaging protrusions (not shown) engage with the guide rails 7a and 7b. A notch 35 (recessed portion) is provided in the center of the lower edge portion 34b. The notch 35 is shaped so that the lower edge portion 34b is recessed upward (in the height direction).

[0043] On the other hand, the auxiliary door 33 is provided with a shielding portion 36 (shielding member). The shielding portion 36 is a portion provided integrally with the upper edge portion 33a of the auxiliary door 33, and has the function of overlapping with the notch portion 35 of the door 34 in the front-to-rear direction when the door 34 is lowered, thereby covering the notch portion 35 from the rear side. Fig. 6(a) shows a state in which the notch portion 35 is shielded by the shielding portion 36, and at this time the notch portion 35 is shielded, blocking communication between the inside and outside of the storage portion 2a of the packing box 2.

[0044] As shown in FIG. 6(b), when the door 34 rises, the notch 35 moves away from the shielding portion 36, and the slot 3 begins to open. Then, when the door 34 moves to the raised position and the auxiliary door 33 tilts backward, the slot 3 becomes fully open, as shown in FIG. 6(c). As shown in FIG. 6(c), the notch 35 is at the same height as the safety confirmation member 6, and the safety confirmation member 6 is exposed to the rear. That is, the safety confirmation member 6 can perform its safety confirmation function via the notch 35.

[0045] In the embodiment shown in FIG. 6, the distance of vertical movement (reciprocating movement distance) of the door 34 is shorter than the distance of vertical movement of the door 4 shown in FIG.

[0046] 6(a) to 6(c) show an example in which auxiliary door 33 is provided with shielding portion 36 that shields notch 35 of door 34, but door 34 may be provided with a sliding, rotating, or removable shielding plate (not shown) instead of shielding portion 36. That is, when door 34 closes insertion slot 3, the shielding plate (not shown) shields notch 35, and when door 34 opens insertion slot 3, the shielding plate (not shown) can be configured to move away from notch 35 in conjunction with the opening and closing of door 34.

[0047] Figure 7 shows the rear of a refuse collection vehicle 41 according to another embodiment different from those of Figures 2, 4, and 6. In the refuse collection vehicle 41, the structure of the door 44 differs from the structure of the door 34 of the refuse collection vehicle 31 in Figure 6. The rest of the structure is the same as the door 34 in Figure 6.

[0048] 7(b) and 7(c), a through-hole 45 is provided in the door 44. The through-hole 45 is provided in the center of the door 44, near the bottom side 44b. That is, the through-hole 45 is provided in the door 44 at the same position as the notch 35 of the door 34 in FIG.

[0049] As shown in Fig. 7(a), when the door 44 is in the lowered position, the through-hole 45 is shielded by the shielding portion 36 of the auxiliary door 33. Also, as shown in Fig. 7(c), when the door 44 is in the raised position, the through-hole 45 is at the same height as the safety confirmation member 6. Therefore, the door 44 does not obstruct the safety confirmation member 6, and the safety confirmation member 6 can perform its safety confirmation function well.

[0050] 7(a) to 7(c) show an example in which auxiliary door 33 is provided with shielding portion 36 that shields through-hole 45 of door 44, but instead of shielding portion 36, door 44 may be provided with a sliding, rotating, or removable shielding plate (not shown). That is, when door 44 closes insertion slot 3, the shielding plate (not shown) shields through-hole 45, and when door 44 opens insertion slot 3, the shielding plate (not shown) can be configured to move away from through-hole 45 in conjunction with the opening and closing of door 44.

[0051] 1 to 7 show an example in which guide rails 7a, 7b are provided on both sides of the insertion opening 3 and the doors 4, 24, 34, 44 move along the guide rails 7a, 7b, but the guide rails 7a, 7b may be omitted and the doors 4, 24, 34, 44 may be connected to the shipping box 2 at multiple locations by a link mechanism (parallel link) not shown. In other words, the link mechanism causes the doors 4, 24, 34, 44 to move to an upper position while avoiding the safety confirmation member 6 backward when in the raised position, and close the insertion opening 3 when in the lowered position.

[0052] In the above embodiment, a surveillance camera was used as an example of the safety confirmation member 6, but instead of a surveillance camera, a device that can confirm surrounding vehicles, objects, people, etc. from the garbage collection truck (e.g., an infrared sensor, an ultrasonic sensor, etc.) may be used.

[0053] Furthermore, the safety confirmation member 6 may be an indicator light or the like that allows surrounding vehicles and people to recognize that the refuse collection vehicle is stopped or in operation (for example, an electric bulletin board, display, etc.).

[0054] The doors 4, 24, 34, and 44 in the above embodiments may be of a manual opening and closing type without a drive device. The present invention can also be effectively implemented in a garbage collection vehicle in which auxiliary springs are provided on the arms 11a and 11b to assist the opening and closing operation of the doors 4, 24, 34, and 44.
