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

[0002] A refuse collection vehicle has a packing box for storing refuse on the loading platform, and an inlet for putting the refuse in the packing box is provided at the rear of the vehicle body. There are many blind spots from the driver's seat behind such a refuse collection vehicle. Therefore, a refuse collection vehicle that can eliminate blind spots by installing a surveillance camera that shows the rear of the vehicle body has been proposed, and such a refuse collection vehicle is disclosed in, for example, Patent Documents 1 and 2. In the refuse collection vehicles disclosed in Patent Documents 1 and 2, a surveillance camera is provided outside the inlet door that opens and closes the refuse inlet, so that the safety of the rear of the vehicle body can be confirmed regardless of the open / closed state of the inlet door. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-314061 A [Patent Document 2] JP 2015-105168 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in conventional garbage collection trucks such as those disclosed in Patent Documents 1 and 2, the surveillance camera is positioned behind (outside) the garbage disposal door, so when the garbage disposal door is open, even if an attempt is made to photograph the garbage disposal, the garbage disposal door falls within the surveillance camera's range and becomes an obstacle to photography.

[0005] Therefore, an object of the present invention is to provide a garbage collection vehicle in which the input 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 problems is a garbage collection vehicle having a shipping box mounted on a vehicle body, the shipping box having a storage section for storing garbage, an opening for inserting garbage into the storage section, and a door for opening and closing the opening, the opening being provided on the rear side of the vehicle body in the shipping box, a fixed wall facing the rear of the vehicle body is provided above the opening in the shipping box, and a safety confirmation member visible from the rear of the vehicle body is provided on the fixed wall, and the door is capable of moving rearward of the safety confirmation member.

[0007] In this aspect, the packing box has a storage section for storing trash, an input port for inputting trash into the storage section, and a door for opening and closing the input port, the input port is provided on the rear side of the vehicle body of the packing box, a fixed wall facing the rear of the vehicle body is provided above the input port of the packing box, and a safety confirmation member visible from the rear of the vehicle body is provided on the fixed wall, and the door is movable rearward of the safety confirmation member and above the safety confirmation member. Therefore, when the door closes the input port, the door is located below the safety confirmation member, and when the door opens the input port to input garbage, the door is located above the safety confirmation member. In other words, when the door closes the input port and when the door opens the input port to input garbage, 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 input port, but also when garbage is being input into the storage section of the packing box. Specifically, if the safety confirmation member is a surveillance camera, the door does not obstruct the surveillance camera's image capture, allowing the camera to capture a good image of the input port and the situation behind the vehicle. Also, if the safety confirmation member is an indicator light, people in the vicinity behind the refuse collection vehicle can see the safety confirmation member. This allows people to know that the refuse collection vehicle is working, alerts them, and helps to avoid dangerous actions such as carelessly approaching the refuse collection vehicle.

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

[0009] According to a second aspect, the packing box is provided with a storage section for storing trash, an input port for inputting trash into the storage section, and a door for opening and closing the input port, the input port is provided on the rear side of the vehicle body of the packing box, a fixed wall facing the rear of the vehicle body is provided above the input port of the packing box, and a safety confirmation member visible from the rear of the vehicle body is provided on the fixed wall. The door is movable behind the safety confirmation member. Therefore, when the door closes the input port, the door is located below the safety confirmation member, and when the door opens the input port to input garbage, the door is located above the safety confirmation member. In other words, when the door closes the input port and when the door opens the input port to input garbage, 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 input port, but also when garbage is being input into the storage section of the packing box. Specifically, if the safety confirmation member is a surveillance camera, the door does not obstruct the surveillance camera's image capture, allowing the camera to capture a good image of the input port and the situation behind the vehicle. Also, if the safety confirmation member is an indicator light, people in the vicinity behind the refuse collection vehicle can see the safety confirmation member. This allows people to know that the refuse collection vehicle is working, alerts them, and helps to avoid dangerous actions such as carelessly approaching the refuse collection vehicle. In this aspect, guide rails are provided on both sides of the insertion opening, and the guide rails extend from at least the height position of the lower end of the insertion opening at least above the safety confirmation member, and 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 bottom surface, lower edge, and near the bottom end of the side of the door. In addition, since 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 the position of the door 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 opening is closed, the upper part of the door can be swung backward when the door rises, thereby preventing the door from coming into contact with the safety confirmation member. As a result, when the door opens the insertion port, the door can move behind the safety confirmation member without coming into contact with or colliding with the safety confirmation member. And since the door can move above the safety confirmation member, the door does not exist behind the safety confirmation member. Therefore, there is no obstacle behind the safety confirmation member, and the safety confirmation member can perform its safety confirmation function.

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

[0011] According to a third aspect, the packing box includes a storage section for storing trash, an input port for inputting trash into the storage section, and a door for opening and closing the input port, the input port is provided on the rear side of the vehicle body of the packing box, a fixed wall facing the rear of the vehicle body is provided above the input port of the packing box, and a safety confirmation member visible from the rear of the vehicle body is provided on the fixed wall. The door is movable behind the safety confirmation member. Therefore, when the door closes the input port, the door is located below the safety confirmation member, and when the door opens the input port to input garbage, the door is located above the safety confirmation member. In other words, when the door closes the input port and when the door opens the input port to input garbage, 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 input port, but also when garbage is being input into the storage section of the packing box. Specifically, if the safety confirmation member is a surveillance camera, the door does not obstruct the surveillance camera's image capture, allowing the camera to capture a good image of the input port and the situation behind the vehicle. Also, if the safety confirmation member is an indicator light, people in the vicinity behind the refuse collection vehicle can see the safety confirmation member. This allows people to know that the refuse collection vehicle is working, alerts them, and helps to avoid dangerous actions such as carelessly approaching the refuse collection vehicle. 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 opening, and the guide rails extend from a height position that is lower than the height position of the bottom end of the insertion opening by at least the protruding length of the protruding engagement portion from the door, to at least the height position of the bottom 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. In addition, since only the protruding engagement part protruding downward of the door engages with the guide rail, the door can swing around the part where the protruding engagement part engages with the guide rail as a base point. Therefore, when the door moves upward, it is possible to change the position of the door by swinging around the part where the protruding engagement part engages with the guide rail as a base point so as not to 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 comprising a storage section for storing garbage, an opening for inserting garbage into the storage section, and a door for opening and closing the opening, the opening being provided on the rear side of the vehicle body of the loading box, a fixed wall facing the rear of the vehicle body being provided above the opening of the loading box, and a safety confirmation member being provided on the fixed wall which is visible from the rear of the vehicle body, the lower part of the door being provided with a recessed portion or a through hole which is recessed in the height direction, the door being capable of opening and closing the opening by raising and lowering behind the safety confirmation member, and the garbage collection vehicle characterized in that when the door opens the opening, the recessed portion or the through hole of the door is at the height position of the safety confirmation member.

[0013] In a fourth aspect of the present invention, a packing box includes a storage section for storing trash, an input port for inputting trash into the storage section, and a door for opening and closing the input port, the input port is provided on the rear side of the vehicle body of the packing box, a fixed wall facing the rear of the vehicle body is provided above the input port of the packing box, and a safety confirmation member visible from the rear of the vehicle body is provided on the fixed wall, and a recessed portion recessed in the height direction or a through hole is provided on the lower part of the door, the door can be raised and lowered behind the safety confirmation member to open and close the input port, and when the door opens the input port, the recessed portion or the through hole of the door is at the height position of the safety confirmation member. Therefore, when the door closes the input port, the door is located below the safety confirmation member, and when the door opens the input port to input garbage, the door is located above the safety confirmation member. In other words, when the door closes the input port and when the door opens the input port to input garbage, 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 input port, but also when garbage is being input into the storage section of the packing box. Specifically, if the safety confirmation member is a surveillance camera, the door does not obstruct the surveillance camera's image capture, allowing the camera to capture a good image of the input port and the situation behind the vehicle. Also, if the safety confirmation member is an indicator light, people in the vicinity behind the refuse collection vehicle can see the safety confirmation member. This allows people to know that the refuse collection vehicle is working, alerts them, and helps to avoid dangerous actions such as carelessly approaching the refuse collection vehicle.

[0014] It is preferable that a shielding member for shielding the recess or through hole of the door 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. Effect of the Invention

[0016] According to the present invention, the safety confirmation member can perform the safety confirmation function well when the door closes the deposit opening and when the door opens the deposit opening to deposit garbage. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The following description will be given with reference to the drawings. As shown in FIG. 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 for storing refuse inside. The periphery of the cargo box 2 is closed, but an opening, an input port 3 (FIG. 2(c)), is provided at the rear. That is, the input port 3 is provided at the rear of the refuse collection vehicle 1. The input port 3 functions as an entrance and exit for refuse. As shown in FIG. 2(b), a fixed wall 5 is provided at the top of the input port 3. That is, the fixed wall 5 is a wall that partitions the top of the input port 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 surveillance camera. The safety confirmation member 6 (surveillance camera) can capture the rear of the input port 3 or the refuse collection vehicle 1.

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

[0021] A receiver (monitor) (not shown) is provided in the driver's seat 12. The image 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 see images of the input port 3 and the rear of the refuse collection vehicle 1 on the receiver.

[0022] As shown in Fig. 2(a) to Fig. 2(c), the slot 3 is provided with a door 4. As shown in Fig. 3(b), the door 4 is a substantially rectangular member having an upper side 4a, a lower side 4b, and side sides 4c and 4d. Arms 11a and 11b are connected to the upper side 4a of the door 4. The door 4 is connected to a drive mechanism (not shown) via the arms 11a and 11b. That is, the arms 11a and 11b are attached to the upper side 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 opening 3. The guide rails 7a, 7b have a generally U-shaped cross section, have engagement grooves 17a, 17b, and extend in the vertical direction. The lower ends 8a, 8b of the guide rails 7a, 7b are disposed at a height position lower than the lower end 3a of the insertion opening 3. Moreover, the upper ends 9a, 9b of the guide rails 7a, 7b are disposed at a height position 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 mutually opposing engaging grooves 17a, 17b of the guide rails 7a, 7b. In other words, the lower portion 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 be smoothly rotated 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, 7b, and the door 4 can rotate (swing) around the engaging protrusions 10a, 10b relative to the guide rails 7a, 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 side 4b of the door 4 abuts or engages with the raised auxiliary door 13, and the insertion opening 3 is closed. In other words, the inside and outside of the storage section 2a of the packing box 2 are blocked off. Also, when the door 4 reaches the raised position, the insertion opening 3 is opened.

[0028] When the door 4 rises, the lower part (engagement protrusions 10a, 10b) of the door 4 rises along the guide rails 7a, 7b, and the upper side 4a of the door 4 moves backward by being pulled by the arms 11a, 11b as shown in FIG. 2(b). That is, 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 opening 3, but since the upper edge 4a of the door 4 moves backward as it rises, the door 4 can rise without contacting 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] Also, 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 is not swung backward, and furthermore, the part of the fixed wall 5 where the safety confirmation member 6 is attached may be recessed (retracted) forward, and the safety confirmation member 6 may be disposed 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 and fully open.

[0031] In the refuse collection vehicle 1 according to this embodiment, the door 4 for opening and closing the inlet 3 for putting refuse into the storage section 2a passes behind the safety confirmation member 6 and ascends and descends, so that the inlet 3 of the storage section 2a can be provided at the rearmost position of the vehicle body 1a. Therefore, the inlet 3 is located at the rearmost position of the vehicle body 1a, and it is easy for an operator to put refuse into the inlet 3.

[0032] In addition, since the dimension of the safety confirmation member 6 protruding rearward can be reduced, the safety confirmation member 6 does not occupy the surrounding space. Therefore, the safety confirmation member 6 is less likely to come into contact with equipment or objects behind the refuse collection vehicle 1. In addition, since the door can move behind the safety confirmation member, there is no need to provide a portion for attaching the safety confirmation member to the rear of the refuse collection vehicle, or for the safety confirmation member to protrude rearward beyond the door, which simplifies the structure of the rear of the refuse collection vehicle. In addition, since the safety confirmation member can be provided directly above the door when it is in the lowered position with the input opening closed, the fixed wall on which the safety confirmation member is attached can be positioned close to the position of the door when it is in the lowered position in the fore-aft direction of the vehicle body, thereby ensuring a large capacity for the storage section of the cargo box.

[0033] A surveillance camera, for example, can be used as the safety confirmation member 6. If the image captured by the surveillance camera can be confirmed on a monitor (not shown) installed in the driver's seat 12, the operator 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 is nothing behind the surveillance camera that would obstruct filming, the surveillance camera can capture good 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 a safety confirmation function.

[0034] Also, an indicator light can be adopted as the safety confirmation member 6. When the door 4 is in the lowered position closing the input port 3, and when the door 4 is in the raised position opening the input port 3, people in the vicinity behind the refuse collection vehicle 1 can see the indicator light. Therefore, the indicator light can tell that the refuse collection vehicle 1 is in operation, ensuring safety.

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

[0036] As shown in Figs. 5(a) to 5(c), the door 24 has an upper edge portion 24a, a lower edge portion 24b, and side edges 24c and 24d, and opens and closes the insertion slot 3 (Fig. 4(b)) by rising and lowering. The side edges 24c and 24d of the door 24 do not have the engagement protrusions 10a and 10b as in the door 4, but instead have protruding engagement portions 15a and 15b on the lower edge portion 24b. The protruding engagement portions 15a and 15b are bent into a substantially L-shape, and one end of each is fixed to the lower edge portion 24b of the door 24. The other ends of the protruding engagement portions 15a and 15b form free ends 16a and 16b, which extend toward the side of the door 24.

[0037] As shown in Fig. 5(b), free ends 16a, 16b of protruding engagement portions 15a, 15b protrude outward (laterally) beyond side edges 24c, 24d of door 24. As shown in Fig. 5(a) and Fig. 5(c), free ends 16a, 16b engage with engagement grooves 17a, 17b of guide rails 7a, 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 side portion 24b of door 24 is located above safety confirmation member 6. In other words, lower side portion 24b is located 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 side portion 24b.

[0039] That is, the protruding engagement parts 15a, 15b protrude downward from the bottom side part 24b of the door 24, and the length of the 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 parts 15a, 15b come close to the upper ends 9a, 9b of the guide rails 7a, 7b, the bottom side part 24b of the door 24 moves upward beyond the safety confirmation member 6. Then, 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 and fully open.

[0040] Here, the safety confirmation function means that, if the safety confirmation member 6 is a surveillance camera, it takes pictures of the drop-in opening 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] Fig. 6 shows the rear of a refuse collection vehicle 31 according to another embodiment different from those of Fig. 2 and Fig. 4. In the refuse collection vehicle 31, the structure of the door 34 and the auxiliary door 33 differs from the structure of the door 4 and the auxiliary door 13 of the refuse collection vehicle 1 of Fig. 2.

[0042] The door 34 has an upper edge portion 34a, a lower edge portion 34b, and side edges 34c and 34d, and the lower portions of the side edges 34c and 34d are provided with engagement protrusions (not shown) similar to the engagement protrusions 10a and 10b of the door 4 shown in FIG. 3(b). The engagement 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 such 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 side 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-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, and communication between the inside and outside of the storage portion 2a of the packing box 2 is blocked.

[0044] As shown in Fig. 6(b), when the door 34 rises, the notch 35 moves away from the shielding portion 36 and the insertion slot 3 starts to open. Then, when the door 34 moves to the raised position and the auxiliary door 33 tilts backward, the insertion slot 3 becomes fully open as shown in Fig. 6(c). As shown in Fig. 6(c), the notch 35 is at the height of 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 vertical movement distance (reciprocating movement distance) of the door 34 is shorter than the vertical movement distance 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 portion 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 portion 35, and when door 34 opens insertion slot 3, the shielding plate (not shown) retracts from notch portion 35, so that the shielding plate can be configured to be linked to the opening and closing of door 34.

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

[0048] 7(b) and 7(c), the door 44 is provided with a through hole 45. 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 a position similar to that of the cutout portion 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 satisfactorily perform its safety confirmation function.

[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 door 44 may be provided with a sliding, rotating, or removable shielding plate (not shown) instead of shielding portion 36. That is, a configuration can be adopted in which the shielding plate (not shown) is linked to the opening and closing of door 44 so that 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) retreats from through-hole 45.

[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 at multiple points to the packing box 2 by a link mechanism (parallel link) not shown. That is, by the link mechanism, the doors 4, 24, 34, 44 move to the 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 sensor (e.g., an infrared sensor, an ultrasonic sensor, etc.) that can confirm surrounding vehicles, objects, people, etc. from the garbage collection truck may be used.

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

[0054] The doors 4, 24, 34, 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 refuse collection vehicle in which auxiliary springs are provided on the arms 11a, 11b to assist the opening and closing operation of the doors 4, 24, 34, 44.
